The present application relies on the disclosure of and claims priority to and the benefit of the filing dates of U.S. Provisional Application No. 61/750,059 and U.S. Provisional Application No. 61/750,089, both filed on Jan. 8, 2013, the disclosures of which are hereby incorporated by reference herein in their entireties.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the field of ball field equipment. More specifically, embodiments of the present invention relate to methods, systems and tools for landscaping. Embodiments of the invention provide manual dirt tamps for compacting soil, clay, or other particular matter, which tamps are useful for baseball or softball field maintenance. Embodiments of the invention also include a scuffle hoe, rake, and interchangeable tool system comprising them. The tools and systems are especially helpful for maintaining a baseball or softball field.

2. Description of Related Art

Since the invention of the game of the baseball and softball there has been a need to create and maintain fields in these sports. The areas of home plate and the pitcher's mound are two parts of the field that are in constant need of repair and maintenance, and also most important to the players of the game. It is essential for the safety and performance of the ball players that the dirt or clay surrounding the pitching rubber and home plate be smooth and firm. This type of smooth playing surface can be achieved by compacting clay with a tamping device. Generally, a tamp is used by repeatedly applying the flat surface of the tamp to loose and uneven dirt or clay to ultimately create a generally hard, smooth and flat surface. Although tamps can be used for a variety of materials and surfaces, the most common use is for packing dirt and clay.

As field maintenance for baseball and softball fields has modernized, tamps too have evolved. Originally, tamps were comprised completely of wood with a flat base and long handle, such as that of a broom stick. Over time, aspects of the tamp, also known as a tamper, have changed to provide a better tool, however, the overall design has largely remained to same.

To overcome the deficiency of using wood, steel was used to replace wood at the base of the tamp but still comprised a wooden handle. The use of a heavier material at the base allowed for the clay to be easily packed down with less force required by the user.

Tamps were later produced comprising steel, or other metals, throughout the entire tool so that both the shaft or handle and the base were comprised of the same material. This, like the advantage above, allowed the user to utilize the weight of the tamp to compact the clay versus using a lot of physical strength. An all steel, or all metal, tamp also provided a much sturdier tamp as the base and handle are typically welded together. One disadvantage however, is that the tool is extremely heavy and requires a certain amount of strength to use properly.

To assist the user in lifting and forcing down the tamp, tamps were created with perpendicular handles. Handles added allow users to easily lift the tamp and provide an additional means for applying a downward force to pack the clay.

Tamps have also been created with adjustable handles, allowing the user to pack dirt or clay from different angles. For example, US Application Publication No. 2005/0025580 entitled “Tamper with Pivoting Handle,” which is incorporated herein by reference in its entirety, describes a tamp, or tamper, in which the handle pivots where the handle meets the base of the tamp. Another example of a tamp with an adjustable handle is U.S. Pat. No. 7,603,780 entitled “Multi-Purpose Tool,” which is incorporated herein by reference in its entirety, which also describes a tamp in which the handle pivots where the handle meets the base of the tamp. Although such tamps provide an added feature, since the handle is held in place so low on the handle, and with little support, such tamps have a tendency to break as the tamp is applied to uneven surfaces due to the strain on the tamp where the base and handle meet.

Additional tamps provide for a tamp with a removable base. For example, US Application Publication No. 2007/0209532 entitled “Yard Waste Tamper,” which is incorporated herein by reference in its entirety, describes a tamp that can be added to the end of a rake to use when tamping leaves or light yard waste. The tamp is held in place by a pressure fit. This type of fit however does not secure the tamp well enough to be applied to harder surfaces such as clay or dirt. Even further, the tamp has a convex face with protrusions to facilitate packing leaves in a bag, which structure is not preferred for providing a smooth, flat surface to a playing field. Another example of a tamp with a removable base is US Application Publication No. 2003/0235470 entitled “Soil Tamper,” which is incorporated herein by reference in its entirety. This reference describes a tamp with a plate and short hollow sleeve capable of receiving a handle. The handle is inserted into the hollow sleeve and secured by a pin. Due to the low height of the hollow sleeve, only a small portion of the handle is secured. This type of attachment is not very sturdy and over time is susceptible to breaking where the handle meets the hollow sleeve.

Earlier efforts to improve tamps are described in U.S. Pat. Nos. 2,234,831 and 3,739,562. Despite attempts to make a stronger, more efficient and easier to use tamp, the prior art has failed to provide a tamp with such characteristics. There is still a need for a tamp that is easy to use, well supported where the handle and base meet, that provides an optionally removable handle, and is strong enough to last the wear and tear of constantly pounding the tool on uneven clay and dirt.

Other tools used for maintaining baseball and softball fields are known, such as hoes and rakes. Common hoes include push & pull hoes, scuffle hoes, loop-hoe edgers, and stirrup hoes. The loop-hoe edger and stirrup hoes, for example, are tools with an elongated handle and tool head in the shape of a loop, usually a trapezoidal loop. The edges of the loop are relatively sharp, making the tool ideal for edging. In the application of baseball and softball field maintenance, loop-hoe edges are used to define the boundary between a granular surface and a grassy area. During use, the tool is positioned such that the loop is perpendicular to the ground surface. The user then performs the edging process by dragging or pushing the loop through the granular surface and along the edge of the grassy area. This action moves, spreads, or otherwise redistributes the granular material and cuts into the edge of the grassy area to shape the grassy area into a desired shape. Similarly, rakes are used to re-distribute the dirt or clay on a playing field and to remove unwanted debris from the field. Since these are common tools for baseball and softball field maintenance, it would be desirable to have a tool system comprising interchangeable tool heads, which tool can be converted from a rake to a hoe, then back again.

One known structure of a hoe head is disclosed in U.S. Pat. No. 8,079,423 entitled “Cultivating Tool,” which disclosure is hereby incorporated by reference herein in its entirety. The patent discloses a tool with a concave shape and narrow scraping blade. Another hoe is described in U.S. Pat. No. 6,152,241 entitled “Dual Blade Hoe,” which disclosure is hereby incorporated by reference herein in its entirety. This patent discloses a tool with two independent blades joined by a curved support.

What is still desired for scuffle hoes for maintaining baseball and softball fields is a more durable tool with multiple scraping blades. Additionally lacking is a system of interchangeable tool heads, especially a tool system comprising a rake and hoe tool head. Thus, there is a need for improved landscaping tools for maintaining baseball and softball fields.

SUMMARY OF THE INVENTION

Embodiments of the present invention relate to systems, tools, and methods used for cultivation and landscaping, particularly on baseball and softball fields.

Embodiments of the invention provide for an improved tamp, and more particularly for a tamp with a plate and shaft, where the height of the shaft is greater than or equal to the length of a side of the plate. In embodiments, support fins are secured between the plate and shaft. All of which provides a durable tool with improved characteristics.

One mode of operation responsible for success of the inventive tamp is that the reinforced tamp plate and shaft, with a shaft height to plate length ratio of 1:1 or greater, provides the capability of withstanding repeated striking of the tamp on a hard surface without breaking the tool at for example the tool pole. Some tamps provide a tamp plate connected directly to and perpendicular to the tamp pole with little or no added support, and do not provide an added shaft between where the plate and pole meet. Since this connection is not well supported this area becomes vulnerable. Over time these tamps have a tendency to break where the plate joins the pole as the tamp is constantly applied to uneven clay and dirt surfaces. Other designs employ a shaft to receive the pole, however, the height of the shaft relative to the length of the plate sides is too short to address this problem of breakage. In such designs, it is the handle (otherwise referred to as the tool pole or tamp pole) that is susceptible to breaking where the handle meets the shaft. In contrast, the invention's connection between the plate and pole is reinforced with a shaft height greater than the plate width. This configuration provides for a stronger connection between the handle and plate, thereby strengthening the area most likely to break and providing for a more durable tool. Further, optionally securing the shaft further up the pole and/or optionally reinforcing the plate and shaft with support fins provides a tamp that is extremely durable.

An embodiment of the invention is a tamp comprising: a steel plate with an upper surface and a lower flat planar tamp face; a hollow shaft, for receiving a handle, disposed on and fixed perpendicular to the upper surface of the steel plate; and multiple support fins disposed on and extending from the upper surface of the steel plate to the hollow shaft, wherein an edge of each fin is disposed relative to the shaft at an angle of 45 degrees or less. In embodiments, the steel plate and shaft can be of unitary, single-piece construction (e.g., molded).

Such tamps can comprise a lower flat planar tamp face having sides of equal length forming a square outline and a shaft height greater than the length of the tamp face sides. In embodiments, the ratio of the height of the hollow shaft to the length of the tamp face side(s) may be in the range of 0.5:1 to 4:1, such as for example 1.2:1 to 2.3:1. In specific embodiments, the ratio of the height of the hollow shaft to the length of the tamp face sides is about 1.1:1, or 1.2:1, or 1.3:1, or 1.4:1, or 1.5:1, or 1.6:1, or 1.7:1, or 1.8:1, or 1.9: 1, or 2:1. For example, in one specific embodiment, the tamp may have a shaft with a height of 11 inches and tamp face sides with a length of 8 inches, which provides a height-to-side ratio of about 1.4:1.

In embodiments, the tamp can have a handle of wood disposed in the shaft, which handle is removable. A portion of the handle and the hollow shaft can be configured with a square cross section and sized appropriately such that the handle is received in the hollow shaft in a slip fit or pressure fit manner. When the handle is disposed in the shaft, it can fit in a manner where there is some or no movement between the shaft and handle. Other materials, such as adhesives and/or screws may or may not alternatively or in addition be used to secure the pole within the hollow shaft.

Support fins can be added for additional support between the handle and the tamp plate. Embodiments with no support fins are also possible. The shape and size of the support fins is not critical and any structure that provides added support between the handle and tamp plate can be used, including for example crescent-shaped fins, rectangular bars or plates, triangular plates, and/or cylindrical bars. In embodiments, each fin can be substantially triangular and have two sides disposed respectively along the upper surface of the plate and the outer surface of the shaft. In this manner the fins can further prevent bending between the shaft and plate and/or between the pole and plate. The fins can also have a semi-circular cut out in a side of the fin to provide some flexibility and allow for a small amount of bending between the plate and shaft during use.

Another embodiment of the invention is a tamp comprising: a metallic plate with a first surface and a second surface disposed parallel to the first surface, wherein the second surface is configured such that the second surface can be used to compact particulate material into a more compressed state when the second surface is pounded against the particulate material; and an open columnar member, for receiving a handle, disposed on and fixed to the first surface of the metallic plate; wherein the metallic plate has sides of equal length forming a square outline and the open columnar member has a height that is greater than the length of the metallic plate sides.

Such tamps may have a planar second surface and may further comprise multiple support members disposed on and extending from the first surface of the metallic plate to the open columnar member. All or a portion of the second surface may comprise indentations and/or projections of any shape or size, such as semi-spherical, pyramidal, and/or box-like. In embodiments, the multiple support members are fins. The fins may be disposed on and extend from the first surface of the metallic plate to the open columnar member, wherein an edge of each fin is disposed relative to the shaft at an angle. In embodiments, each fin is substantially triangular, and an edge of each fin forming the hypotenuse of a right triangle may be disposed relative to the shaft at an angle of 45 degrees or less, such as 40 degrees, or 35 degrees, or 30 degrees, or 25 degrees, or 20 degrees, or 15 degrees, or 10 degrees, or 5 degrees, or any range in between any of these endpoints. Each fin may have a semi-circular cut out in a side of the fin.

Methods of using tamps are also included within the scope of the invention. Such methods can include using any of the tamp configurations described in this specification. For example, one such method can comprise using a tamp comprising: a steel plate with an upper surface and a lower flat planar tamp face; a hollow shaft, for receiving a handle, disposed on and fixed perpendicular to the upper surface of the steel plate; and multiple support fins disposed on and extending from the upper surface of the steel plate to the hollow shaft, wherein an edge of each fin is disposed relative to the shaft at an angle of 45 degrees or less, wherein the use comprises repeatedly pressing the lower flat planar tamp face against a ground surface to compact the soil with a downward force.

Embodiments of the invention solve the problem of strength and longevity of use of tamps. Embodiments of tamps according to the invention can be made with a shaft, a base plate, and fins secured together and connected to a pole, also referred to as the handle. The tamps can be made with wood, metal, plastic, or any combination thereof.

An embodiment of the present invention provides for an improved tamp comprising a shaft perpendicularly connected to a base plate, where the shaft and base are further secured together by one or more support fins and where the shaft is connected to a pole/handle. In embodiments, the shaft, base plate, and/or support fins can be molded as a single unitary piece or joined together from one or more independent pieces to form a tamp.

Embodiments of the invention also provide a scuffle hoe Aspect 1 comprising: an elongated tool head having a hollow semi-cylindrical shape; wherein the tool head has an outer surface and an inner surface and each surface is curved between any two points on the outer surface or any two points on the inner surface; wherein the outer and inner surfaces intersect to provide a blade tip for each blade.

Such scuffle hoes can comprise scuffle hoe Aspect 2, which is the scuffle hoe of Aspect 1 with a distance between blade tips of between 2 to 5 times greater than a perpendicular distance measured from a blade tip to the outer surface of the tool head at its center.

Scuffle hoes of the present invention can include scuffle hoe Aspect 3, which is the scuffle hoe of either Aspect 1 or 2 comprising outer and inner surfaces having a curvature in a first direction forming the hollow semi-cylindrical shape and outer and inner surfaces having a curvature in a second direction to form the blade.

Tool embodiments of the invention also include a rake Aspect 1 comprising: an elongated tool head having a plurality of tines; a support bracket with a C-shaped track fixed to one side of the tool head; and two support bars disposed in the C-shaped track in a manner such that the support bars are supported by three surfaces of the C-shaped track.

Rakes of the invention can further comprise a rake of Aspect 2, which is the rake of Aspect 1 comprising an elongated handle attached to the support bars in a releasable or non-releasable manner.

Such rakes can include rakes of Aspect 3, which is a rake of either Aspect 1 or 2 having at least a portion of the handle with planar sides and support bars each having a planar surface, such that the handle is attached to the support bars in a manner to provide for contact between the planar surfaces of the support bars and at least two planar sides of the handle.

Embodiments further provide a tool system Aspect 1 with interchangeable tool heads comprising: a handle with a polygonal base and a cylindrical body; two support bars each comprising an elongated planar bar shaped to provide a first leg disposed perpendicular to a second leg, wherein the first legs of the support bars are attached to the polygonal base of the handle in a releasable manner; a plurality of tool heads operably configured for releasable attachment with the second legs of the support bars.

Such tool systems can comprise tool systems of Aspect 2, which comprise a plurality of tool heads including a rake head from any one or more of rake Aspects 1 or 2 and a scuffle hoe head from any one or more of scuffle hoe Aspects 1, 2, or 3. Even further, the support bars can be connected to the tool heads in a manner that provides for articulation between the handle and the tool head to provide the handle at any desired angle between the user and the surface being maintained.

Specific tool systems of the invention can comprise tool systems of Aspect 3, which comprise a rake head from any one or more of rake Aspects 1 or 2 and which rake or tool head comprises an elongated tool head having a plurality of tines and a support bracket with a C-shaped track fixed to one side of the tool head, wherein the second legs of the support bars are operably configured such that when disposed in the C-shaped track the second legs of the support bars are supported by three surfaces of the C-shaped track.

Tool systems of Aspect 4 of the invention can alternatively or additionally comprise a scuffle hoe tool head of any one or more of scuffle hoe Aspects 1, 2, or 3, which scuffle hoe tool head comprises an elongated tool head having a hollow semi-cylindrical shape, and wherein the tool head has an outer surface and an inner surface and each surface is curved between any two points on the outer surface or any two points on the inner surface, and wherein the outer and inner surfaces intersect to provide a blade tip for each blade.

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS OF THE INVENTION

Reference will now be made in detail to various exemplary embodiments of the invention. It is to be understood that the following discussion of exemplary embodiments is not intended as a limitation on the invention. Rather, the following discussion is provided to give the reader a more detailed understanding of certain aspects and features of the invention.

In accordance with embodiments of the present invention, provided is a tamp comprising a shaft perpendicularly connected to a base plate, where the shaft and plate are further secured together by fins disposed along substantially the entire length of the plate and/or the height of the shaft. The height of the shaft can be greater than or equal to the length of one side of the plate. Further, the tamp can be connected to a pole or handle to provide leverage to a user when using the tamp. Such tamps provide a durable construction with improved performance characteristics over that of existing designs.

FIGS. 1-5 illustrate an embodiment of the inventive tamps, while FIGS. 6 and 7 illustrate embodiments of individual tamp components. As shown, a tamp 20 is provided which comprises: a steel plate 26 with an upper surface 26A and a lower flat planar tamp face 26B (shown in FIG. 7); an open columnar member 24, for receiving a handle 28, disposed on and fixed perpendicular to the upper surface of the steel plate; and multiple support members 22 disposed on and extending from the upper surface of the steel plate to the hollow shaft, wherein an edge 25 of each fin 22 is disposed relative to the shaft 24 at an angle of 45 degrees or less.

More specifically, the illustrated tamp 20 comprises a square metal base plate 26, a metal shaft 24, 4 metal fins 22 (3 are shown) welded to the plate 26 and shaft 24, and a wooden handle 28 inserted into the hollow shaft 24. In preferred embodiments, the metal is steel. The tamp 20 can be cast or one or more of the individual components welded together. One side of the base plate 26, otherwise referred to as the lower flat planar tamp face (shown as 26B in FIG. 7), is configured such that the plate can be repeatedly pounded against a surface such as the ground to compact the particulate material into a more compressed state. This tamp plate 26, also referred to as a plate, base plate or base of the tamp, is the part of the tool which comes in contact with the dirt or clay. This flat substantially planar surface of the plate, when forcefully applied to the ground by a user, creates a flat, smooth clay or dirt surface by compacting particulate material into a compressed state. It is preferred that this lower surface of the tamp plate is smooth and does not comprise protrusions. If used for another purpose, such protrusions may prove useful and can be included.

For ball fields, such as baseball and softball fields, it is preferred for the clay or dirt to be packed tightly so that the clay or dirt will remain flat and in place for an extended period of time. In order to efficiently pack down clay or dirt it is desirable to have a tamp 20 with a plate 26 large enough to cover a great amount of area, yet small enough that the tamp 20 is easy to operate. The greater the size of the tamp 20, the greater the weight of the tool. According to embodiments of the invention, the face plate 26 can be a planar sheet of metal with dimensions ranging in size from about 1 inch to 18 inches for the length of one or more side. For example, a plate 26 of the tamp 20 can be square and measure 2×2, 3×3, 4×4, 5×5, 6×6, 7×7, 8×8, 9×9, 10×10, 11×11, or 12×12 inches square, with preferred embodiments being an 8 inch by 8 inch square metal plate. Rectangular plates 26 are also possible, with measurements for example ranging from 1-18 inches for one or more of the sides, such as a 2×8, or a 3×9, or a 4×10 inch rectangular plate. Additionally the thickness, or height, of the plate 26 can range from about 0.1 inches to 5 inches, including 0.5 inches, ¼ inch, ¾ inch, 1 inch, 1.5 inches, 2 inches, 2.5 inches, 3 inches, 3.5 inches, 4 inches, or 4.5 inches, or any thickness in between, with preferred embodiments comprising a plate thickness of 0.5 inches or 0.25 inches. While preferred embodiments of the invention comprise a plate 26 made of metal, particularly ferrous alloys such as steel, plate 26 can also be made from plastic, wood, aluminum alloys (e.g. Alnico, Duralumin), copper or copper alloys (e.g. brass, bronze), nickel alloys (e.g. Alumel, Chromel), platinum, titanium or any other metal or alloy. Further, though in preferred embodiments the plate shape is square, the tamp plate 26 may also be rectangular, circular, triangular, pentagonal, hexagonal, heptagonal, octagonal, star shaped, or have any irregular polygon shape, whether convex or concave.

FIG. 2 also illustrates that, in embodiments, the height 24L of the shaft 24 can be greater than the length 26L of a side 26S of the plate 26, providing a height to length ratio greater than 1:1. For example, for a tamp 20 with an 8×8 plate and an 11 inch shaft, the height to width ratio would be about 1.4:1. The ratio of the shaft height to plate side length can for example be 1.2:1, 1.3:1, 1.4:1, 1.5:1, 1.6:1, 1.7:1, 1.8:1, 1.9:1, 2:1, 2.1:1, 2.2:1, 2.3:1, and so on.

Also shown in the figures is that the angle between the shaft 24 and the outside edge 25 of the fin 22 can measure between 0-90 degrees, such as less than 45 degrees. Additionally, the angle of the fin 22 between the edge of the shaft 24 and the outside edge 25 of the fin 22 can be any angle between 0 and 90 degrees, with preferred embodiments having an angle less 45 degrees. Embodiments can include fins 22 with an edge 25 disposed at any angle to the shaft, including for example from 0-90 degrees, such as from 5-85 degrees, 10-75 degrees, 15-65 degrees, 20-55 degrees, 25-50 degrees, 30-40 degrees, 35-60 degrees, 45-70 degrees, or 35-45 degrees, or any range or value in between any of these stated values. In embodiments, the number of fins 22 may correspond to the number of corners or sides on the base plate 26, and the size of the fins 22 may correspond to the size of the base plate 26 and shaft 24. The number of fins 22 can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 and so on. Fin placement may be along the diagonal between the shaft 24 and a corner of the plate 26 and/or perpendicular between the shaft 24 and a side of the plate 26 and/or somewhere between. Fin placement may also be random, so long as the fin 22 provides support and is connected to both the plate 26 and the shaft 24. The fins are preferably provided on the tamp in a manner that increases the distance of the handle from the moment of impact to decrease the amount of stress experienced by the tool during use, especially at the transition point between the handle and tamp plate. In embodiments each fin 22 may also comprise a semi-circular cut out 23 on one side of the fin 22 in order to aid in absorbing the impact felt by the user and the tool 20 as the tool 20 hits the ground. The cut out 23 provides for flexibility between the plate 26 and the shaft 24 by allowing the fin 22 to bend when the tool impacts the ground with an amount of force. The cut out 23 can also be any shape, including but not limited to, a triangle, a square, a pentagon, a circle, a star shape or any irregular shape. The cut out need not be “cut” out of the material, rather the fin can be molded or formed in any such desired configuration providing for a passageway between the fin and shaft when joined thereto. In preferred embodiments cut out 23 is located in the range of about 0.5-2 inches, such as 0.7665 inches, from the base of the tamp 20, however the cut out 23 may be placed anywhere on the fin 22. Additionally, in preferred embodiments the fins 22 are made of the same material as the shaft 24 and plate 26, however all or some of the parts of the tamp 20 may optionally be comprised of the same or different materials. For example, fins 22 can be made of metal, wood, plastic, or any combination thereof.

According to embodiments of the invention, the fins 22 may be secured to the plate 26 and shaft 24 by means suitable for the material the parts are comprised of. In some embodiments, the tamp shaft 24 and tamp plate 26 can be joined together through a means for fastening. The means for fastening can include welding, glue, adhesive, one or more screws, one or more nails, or pins, or any combination thereof to hold the pieces together. Additionally or alternatively, the fins 22 may fasten to the plate 26 and shaft 24, particularly by a hinge, or latch fastener or by interference fit. The fins 22 may also be removable by inserting the fins 22 into a track disposed on the shaft and/or plate into which the fins 22 can be inserted by sliding engagement. Moreover, embodiments of the invention can include a plate 26, shaft 24, and fins 22 formed as a single part construction of one material. The fins 22 of the invention provide added strength to the inventive tamp 20 creating a tamp that is extremely durable and built to withstand the wear over time.

In embodiments, the tamp plate 26 is connected perpendicularly to one end of the tamp shaft 24 in order that the pole or handle 26 may be joined with the plate 26 through the opposite end of the shaft 24. In preferred embodiments, the base of the hollow square tamp shaft 24 is centrally secured to the plate 26, leaving the other end of the shaft 24 for receiving the tamp pole or handle 28. The plate 26 may be, in embodiments, 6 inches×6 inches, 7 inches×7 inches, 8 inches×8 inches, 9 inches×9 inches, 10 inches×10 inches, 11 inches×11 inches, 12 inches×12 inches, or more.

Any combination of these dimensions may be used for a rectangular or square plate. In preferred embodiments, the outside diameter of the tamp shaft 24 is 2 inches by 2 inches and 11 inches in height, with each side of the shaft comprising a thickness of about 0.25 inches. The thickness can be any width ranging from 0.1 inch to 2 inches, including but not limited to 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, 1.8, or 2.0 inches. In other embodiments the tamp shaft 24 can be located eccentrically on the plate 26 and can range in height from 3 inches to 15 inches, including a height of 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, or 14 inches. The width and length of the shaft 24 can also range in size from 0.5 inches to 5 inches, including 1 inch, 1.5 inches, 2 inches, 2.5 inches, 3 inches, 3.5 inches, 4 inches, or 4.5 inches. The height of the tamp shaft 24 can vary as long as the shaft 24 is a sufficient length to connect with the plate 26 and support fins 22, and be able to connect with the pole 28. In embodiments the height of the shaft 24 is greater than or equal to the length of the plate handle, with a height:length ratio of 1:1 or greater. Although in preferred embodiments hollow shaft 24 is a square tubular shape, the shaft 24 may also be rectangular, circular, triangular, pentagonal, hexagonal, heptagonal, octagonal, or any substantially tubular shape. Additionally, the shaft 24 may be solid in which the shaft can be the pole itself. Also, the corners or edges of the shaft may be sharp corners or substantially rounded. Additional elements of the shaft 24 in preferred embodiments may include two holes 24H or voids in two opposite sides of the shaft, for a total of 4 holes. Other embodiments may include any number of voids, such as 1, 2, 3, 4, 5 or 6 holes or voids. The purpose of which provide a means of securing the pole or handle in the shaft, such as using a pin extended from one side of the shaft, through the pole, to the other side of the shaft, or using screws. Additionally, in embodiments the shaft can be made from any material such as any metal such as steel, aluminum, or titanium or the shaft can be made from plastic, wood, or any other material suitable for field tools. In preferred embodiments, the shaft and plate are comprised of the same material.

The tamp shaft 24 and tamp plate 26 may be joined or fastened in any manner suitable for joining two pieces of the same material together. In some embodiments, the tamp shaft 24 and tamp plate 26 can be joined together through a means for fastening. The means for fastening can include welding, glue, adhesive, one or more screws, one or more nails, or pins to hold the pieces together.

Moreover, embodiments of the invention include a plate 26 and shaft 24 formed as a single part construction, such as by casting the part as one piece or forming the tool by 3D printing. The means in which the shaft 24 and plate 26 are held together can vary in embodiments as long as the connection between the two parts is strong and durable, capable of withstanding the strain applied when the user hits the tool on the ground. An embodiment can include a hinge (not shown) that intervenes between the shaft 24 and the plate 26 to provide angular rotation of the shaft 24 or plate 26. Other embodiments include no intervening hinge between the shaft 24 and plate 26 such that the plate 26 and shaft 24 are held together at a fixed angle. Preferably, the shaft 24 is held fixed at a perpendicular angle to the plate 26, although other angles are possible within a range of 45 degrees from perpendicular.

To ensure the connection between the tamp plate 26 and tamp shaft 24 is highly durable, embodiments of the invention provide for fins 22 between the plate 26 and shaft 24 to add additional support. In preferred embodiments the tamp 20 is supported by four fins 22 located at the four corners of the square plate 26, extending diagonally to the center of the plate 26 where the plate 26 and shaft 24 meet, and up the entire length of the shaft 24. Each fin 22 can be shaped like a right triangle with sides that are 4.32 inches by 11 inches and are 0.125 inches thick and where the angle of the fin 22 at the top of the shaft 24, between the edge of the shaft 24 and the outside edge of the fin 22 measures less than 45 degrees. The part of the fin 22 (side 22A) measuring approximately 4 inches is the side that connects with base plate 26, where the side measuring 11 inches (side 22B), connects to the full length of the shaft 24. In embodiments, the length of sides 22A and 22B can range from 1 to 18 inches, including sides measuring 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, or 17 inches.

Important to any user of a tamp 20 is the pole or handle 28 that is connected to overall base 26 of the tamp 20. The pole 28 may be any rod shaped material extending from the plate 26 of the tamp 20 to a reasonable height for the user. In preferred embodiments the tamp pole 28 is circular wooden rod, resembling a broom stick, with a square shaped end, or an end that complements the cross sectional shape of the interior of the shaft, such as a round or triangular end. The squared end of the rod 28 is inserted into the shaft 24 of the tamp 20 and provides a fit to minimize movement between the pole 28 and shaft 24. The circular part of the pole 28 provides for a comfort grip. Embodiments may include attachment of other tools at the end of the tamp pole 28 opposite the base 26 of the tamp 20, or embodiments where the pole 28 terminates at an end that has no additional attachment attached to the pole 28.

In embodiments, the base of the pole 28 comprises two holes drilled partially or completely through the pole 28 to align with the holes 24H or voids of the tamp shaft 24. In preferred embodiments the holes are located 2.75 inches from the bottom of the pole 28 but can be placed at any location so long as the holes in the handle align with the holes in shaft. In embodiments, the pole 28 may also comprise more or less than two holes and can range for example from 0-5 holes, such as 1, 2, 3, 4, or 5 holes or voids. The holes or voids in the pole 28 provide a means of securing the pole within the shaft 24 of the tamp 20. It is important that the two pieces are held together well as they will have to withstand the forces of lifting the base 26 of the tamp 20 and striking it on the ground. Embodiments of the inventive tamp handle 28 may be secured together by a variety of means such as welding, gluing, screwing, nailing, or bolting, or any combination thereof with preferred embodiments using pins to secure the handle 28 in place within the shaft 24. In preferred embodiments the handle 28 is easily removable and not permanently fixed to the rest of the tamp 20, so as to provide for easy replacement if required.

FIGS. 6 and 7 provide detailed measurements for various components of a representative tamp 20 according to embodiments of the invention. In preferred embodiments the shaft 24 of the tamp 20 is 2 inches by inches and measures 11 inches in height. Going through the shaft 24 are two sets of circular holes 24H on opposite sides of the shaft located about 2.75 inches and 7.5 inches from the base of the shaft. The base plate 26 of the tamp is 8 inches by 8 inches and measures 0.5 inches in height. The fins 22 of the shaft correspond to the height of shaft, and length of the plate to form a right triangle measuring 11 inches by 4.3192 inches; where the angle of the fin 22 at the top of the shaft 24, between the edge of the shaft 24 and the outside edge of the fin 22 measures 21.534 degrees. A semi-circle 23 is disposed on side 22B of the fin. The bottom edge of the semi-circle 23 is disposed 0.7665 inches from the bottom of the fin and the top of semi-circle 23 is disposed 8.0165 inches from the top of the fin.

Embodiments of the invention also provide a tool system comprising a handle, a first and second support bar or bracket, a rake attachment, and/or a hoe attachment. Preferably, the system comprises means for attaching the tool heads to the handle in a releaseable manner.

Each component can be made of any material, such as wood, plastic, or metal. The interchangeable handle 38, shown as the embodiment in FIGS. 1-5, is preferably made of wood or composites. The shape of the handle is not critical, however, in embodiments the handle 38 comprises a portion having planar surfaces to allow for secure attachment of the support bars 32 to the surface of the tool handle 38. In embodiments, provided is a handle 38 comprising a polygonal shaped base, a polygonal or cylindrical shaped main body, and a cube or hemispherical shaped tip. The handle 38 can be cylindrical or a combination of cylindrical and polygonal.

The handle 38 can be molded, carved, or shaped from individual components and attached together to form the handle, or the handle can comprise a single, seamless piece of material which is molded, carved, or shaped to reflect one or more distinct sections. In one embodiment, a base with a square cross section (e.g., polygonal base) provides additional reinforcement when the interchangeable handle is in operable communication with an attachment by preventing rotational motion of the handle when placed between a first and second support bracket or support bar.

The base of the handle 38 can comprise one or more void, such as two voids, traversing the enclosed volume of the square base and causing two holes in the surface in each of two parallel sides of the square base section. These voids and corresponding holes can be any diameter to accommodate a desired sized screw, bolt, peg or other securing means for securing the support bars to the handle. In embodiments, the holes are about 0.3750 inches in diameter, such as 0.1 to 0.5 inches, and are capable of receiving a fastening device such as a screw, a peg, bolt, or pin. The fastening device serves to operably connect the interchangeable handle to a tool attachment. The cylindrical main body and hemispherical tip sections of the handle provide a comfortable area for the user to grasp and operate the handle.

The first and second support brackets 32, shown together as the embodiments depicted in FIGS. 1-5 and individually in FIGS. 8-13, are preferably made of metal and each provide a main section 32A, an angled section 32B, and an interface section 32C. In embodiments, the support bars 32 (as shown in the figures) can comprise a planar bar that is shaped (e.g., bent) to provide a first leg 32A disposed perpendicular to a second leg 32C. The support bar 32 can be a single piece or can be formed from multiple components for example welded or attached together to form the support bracket. Depending on the material, the support bar 32 can be molded, forged, carved, or shaped to reflect the distinct sections.

Each support bar 32 has a length between 5 and 24 inches, such as between 14 and 18 inches along the long axis of the bracket. The support bar 32 can have a width of between half an inch to 3 inches, such as between 1-2 inches. The support bar 32 can have a thickness ranging from about 0.1 to 1 inch, with thicker and/or wider brackets being stronger.

In one embodiment, the main section 32A (e.g., first leg of the support bar) has a length of 10 inches, such as from 4-18 inches, and comprises a rectangular planar surface with two holes 32H for receiving a fastener. Each hole 32H is approximately 0.375 inches in diameter, such as from 0.1-0.5 inches, and is centrally disposed between the parallel 10 inch sides of the surface, approximately 0.75 inches away from each of these parallel sides, such as 0.2-1.5 inches, or a corresponding distance depending on the overall length of the tool head. The first leg 32A of the support bar 32 is attached to a side of the handle 38 and the planar surface of the support bar 32 contacts or interfaces with a side of the handle 38. The interface section 32C of each support bracket (e.g., second leg) is disposed perpendicular to the main section 32A, and can be attached to the main section 32A through the angled section 32B. The first leg 32A, second leg 32C, and transitional portion 32B between the first 32A and second leg 32C can be disposed such that when two support bars are used, the two combine to provide a generally Y-shaped support for attaching the handle to the tool heads. The interface section 32C, or second leg, has a minimum length of 1 inch, such as from about 1-4 inches, and comprises a rectangular planar surface with one hole for receiving a fastener. In embodiments, depending on the overall size of the tool, the length of this leg 32C can be shorter than one inch, such as about 0.1-1 inch. In one embodiment, the hole is approximately 0.375 inches in diameter, and is centrally disposed between the parallel 1 inch sides of the surface, approximately 0.75 inches away from each of these parallel sides. The angled section 32B of each support bracket 32 connects or provides the transition between the two previously described sections forming a first angle between 15 and 30 degrees with the main section, such as from about 5-45 degrees, and a second angle between 105 and 120 degrees with the interface section, such as about 90 to 145 degrees. In one embodiment, the first angle is approximately 21 degrees while the second angle is approximately 111 degrees. The angled section 32B has a length between 3 and 7 inches, and comprises a rectangular planar surface with no holes or voids. The second leg 32C of the support bars is attached to the tool head.

The rake attachment 45, an embodiment of which is shown in FIGS. 1-5, 10, and 11 is preferably made of metal or polycarbonate and provides a rake head 46 and a rake head brace 44 (e.g., support bracket). The rake head 46 has a width between 30 and 40 inches, such as 10 to 45 inches, a uniform thickness between 0.5 and 1.5 inches, and comprises an array of teeth 47 or tines, and one or more holes 46H for receiving a fastener. In one embodiment, the rake head 46 has 4 holes 46H for receiving a fastener, and a width of 36 inches, but any width and number of holes and fasteners can be used. The fasteners can be used for attaching the support bracket 32 to the backside of the rake 40 and/or for attaching the second leg 32C of the support bars 32 to the rake head 46. The array of teeth 47 is formed by an alternating distribution of voids and teeth. Each tooth 47 comprises a contact section and a distributed section. The contact section is directly in contact with a ground surface during operation, and can comprise a rectangular column height between 1.5 and 2 inches and a width between 0.1 and 0.5 inches. In one embodiment column height is 1.6415 inches, and column width is 0.375 inches. The distributed section is approximately 0.8585 inches tall and links each contact section to the main rake head 46 to form the array of teeth 47. In embodiments, the teeth 47 can be formed according to conventional rakes. The sections of each tooth 47 are formed as a result of alternating voids in the array of teeth. Each void comprises a rectangular column volumetrically equivalent to that of the tooth, and a top section. The top section forms preferably a parabolic or triangular shape with the main rake head, causing a corresponding distributed section disposed between two voids, for each tooth. Two of the four holes 46H for receiving a fastener are each disposed 2.75 inches from the width midpoint of the rake head structure, on either side of the midpoint. Each of these two holes is approximately 0.375 inches in diameter. The other two holes for receiving a fastener, each with a diameter of 0.25 inches, are each disposed 8 inches, or a proportionate distance depending on the tool, from the width midpoint of the rake head, on either side of the midpoint.

The rake head brace 44, or support bracket for the back of the rake 40, an embodiment of which is shown in FIGS. 1, 2, 4, 10 and 11, serves to facilitate a more secure connection between the first and second support brackets 32 and the rake head 46. The rake head brace 44 has a width between 15 and 20 inches, a height between 1 and 3 inches and a uniform thickness between 0.3 and 2 inches, and comprises a rectangular planar surface 44A, a depressed channel 44C on one side of the surface, and four holes 44H for receiving a fastener. It is not necessary that the depressed surface be present, however, this will provide for greater support for the support bracket 32 placed within the channel. The planar surface comprises two parallel raised edges 44B, along the long axis of the brace, on one side of the surface. These edges are perpendicular to the planar surface, and form a depressed channel 44C between the edges on that side of the planar surface. In one embodiment, the rake head brace 44 has a width of 18 inches. The channel 44C has dimensions of 18 inches by approximately 1.5 inches. Two of the four holes 44H for receiving a fastener are each disposed 2.75 inches from the width midpoint of the rake head brace 44, on either side of the midpoint. Each these two holes 44H is approximately 0.375 inches in diameter. The other two holes 44H for receiving a fastener, each with a diameter of 0.25 inches, are each disposed 8 inches from the width midpoint of the rake head brace 44, on either side of the midpoint.

The support bracket 44 for the backside of the rake head 46 preferably comprises a C-shaped channel 44C for receiving a leg of the support bars 32 that are attached to handle 38. Such a configuration provides three surfaces for interacting or engaging with a leg 32C of the support bars 32, since the support bars are planar. For example, three of the four surfaces of the legs 32C of the support bars 32 are disposed within the C-shaped channel 44C. When attached to the rake head 46 within the channel 44C, the three surfaces of the support bars 32 will interface with three sides of the channel 44C to provide for a secure handle during use.

The rake tool 40, an embodiment of which is shown in FIGS. 1-5, may be configured by following a sequence including but not limited to the following steps. When operably configured, the entire non-channel side of the rake head brace 44 is firmly adjacent to the rake head 46. The two components are arranged such that the midpoint of each component are the same, and the 0.25 inch diameter holes 46H, 44H on each side of the rake head 46 and rake head brace 44 midpoints are aligned. Fasteners are then used in each pair of aligned holes to secure the rake head brace 44 to the rake head 46. The 0.375 inch diameter holes on each component should also form two aligned pairs, and each of these pairs is then aligned with the corresponding hole on a support bracket interface section. Fasteners are then used in each pair of the aligned holes to secure the channel side of the rake head brace 44 to the first and second support brackets 32. The support brackets 32 are then attached to the appropriate opposing sides of the interchangeable handle 38 by aligning the 0.375 inch holes 32H on each support bracket 32 with the corresponding holes on the handle 28. A fastener is used to in each of the two trios of two opposed support bracket holes and one traversal void.

The C-shaped channel 44C offers additional strength to the component junctions by restricting the rotational motion of the first and second support brackets 32 when received by the channel. The channel depth is approximately the same thickness as the support bracket 32, and the channel height is roughly the same as the support bracket width. When fastening each support bracket to the rake head 46 and rake head brace 44 through the 0.375 inch holes, the external rotational force applied to the fastener (in the case of a bolt or screw) would then yield a greater torque on the components because the applied force would not be lost to the rotational motion of the other components. An increase in torque would then lead to a more rigid connection and a faster assembly or disassembly time and less required applied force. A more rigid connection allows the tool to operate more effectively for a longer period of time because the junction will not loosen, and will consistently transfer all force applied by the operator to the contact section of the rake.

The rake head can comprise an elongated tool head 46 with a plurality of tines 47 and a support bracket 44 with a C-shaped track 44C fixed to one side of the tool head, wherein the second legs 32C of the support bars 32 are operably configured such that when disposed in the C-shaped track 44C the second legs 32C of the support bars 32 are supported by three surfaces of the C-shaped track 44C.

The hoe attachment 34, embodiments of which are shown in FIGS. 1-5, and 8 and 9 is initially in an unmolded form and comprises two holes 34H for receiving a fastener, two parallel diverging edges, and a flat, preferably metal, planar surface as shown in FIGS. 8 and 9. In one embodiment, the attachment has a width of 6.5 inches, a height of 4.5 inches, and an approximate thickness between 0.5 and 1.5 inches, in its unmolded form. The two holes 34H for receiving a fastener are disposed on the lower half of the surface, each 0.5625 inches from the left and right sides respectively, and both 1.25 inches above the lower boundary of the surface. Each hole is 0.25 inches in diameter. In its molded form, the attachment 34 has the same width as in the unmolded form, but now has a height of 2.7434 inches, and a curvature depth of 1.1937 inches as shown in FIGS. 8 and 9. The molded form does not change the relative position of the two holes 34H for receiving a fastener. The parallel diverging edges represent the upper and lower boundaries and are specifically shown in FIGS. 8 and 9.

In embodiments, the scuffle hoe 30 comprises an elongated tool head 34 having a hollow semi-cylindrical shape, and wherein the tool head 34 has an outer surface and an inner surface and each surface is curved between any two points on the outer surface or any two points on the inner surface, and wherein the outer and inner surfaces intersect to provide a blade tip for each blade. Scuffle hoes according to the invention can comprise multiple scraping blades as shown, where one blade is used for cutting and the other blade is used for smoothing.

The hoe tool 30, an embodiment of which is shown in FIGS. 1-5, may be configured by a sequence including but not limited to the following steps. When operably configured, the hoe attachment 34 is attached to the interchangeable handle 38 using a first and second support bracket 32. The hole 32H of the interface 32C section of each support bracket 32 is aligned with the corresponding hole 34H on the hoe attachment 34. Fasteners are then used in a first and second pair of the aligned holes 32H, 34H to secure the support bracket 32 to the hoe attachment 34. The support brackets 32 are then attached to the appropriate opposing sides of the interchangeable handle 38 by aligning the 0.375 inch holes 32H on each support bracket 32 with the corresponding holes on the handle 38. A fastener is used in each of the two trios of two opposed support bracket holes and one traversal void.

Further embodiments of the invention provide an interchangeable tool system for maintaining a baseball and softball field. The system comprises an interchangeable handle 38, a hoe attachment 34, a rake attachment 45, a first and second support bracket 32, and several fastening devices. The interchangeable handle 38 is operably configured to connect with the hoe attachment 34 or the rake attachment 45, and optionally the shaft 24 of the tamp 20. The interchangeable handle 38 is preferably made of wood or composites and provides a polygonal shaped base, a polygonal shaped main body, and a hemispherical shaped tip. The handle 38 can be molded, forged, carved, or shaped from individual components and attached together to form the handle or can comprise a single, seamless piece of material which is molded, forged, carved, or shaped to reflect these distinct sections.

The support brackets 32 are preferably made of metal and each provide a main section 32A, an angled section 32B, and an interface section 32C. Each of these sections can be molded separately and welded or otherwise attached together to form the support bracket 32, or the support bracket 32 can comprise a single, seamless piece of material which is molded, forged, carved, or shaped to reflect the distinct sections. Interface section 32C of the support bracket 32 is disposed perpendicular to main section 32A, and is attached to main section 32A through the angled section 32B. In the illustrated embodiment, the main section 32A is the longest section of the three, but this is not a limitation of the claimed invention.

The rake attachment 45 is preferably made of metal and provides a rake head 46 and a rake head brace 44. The rake head 46 comprises an array of teeth 47, and four holes 46H for receiving a fastener. The array of teeth 47 is formed by an alternating distribution of voids and teeth. Each tooth 47 comprises a contact section and a distributed section. The contact section is directly in contact with a ground surface during operation, and comprises a rectangular column. The distributed section links each contact section to the main rake head to form the array of teeth. The sections of each tooth 46 are formed as a result of alternating voids in the array of teeth. The rake head brace 46 comprises a rectangular planar surface, a depressed channel 44C on one side of the surface, and four holes 44H for receiving a fastener. The planar surface comprises two parallel raised edges, along the long axis of the brace, on one side of the surface. These edges are perpendicular to the planar surface, and form a depressed channel 44C between the edges on that side of the planar surface.

The hoe attachment 34 in its molded, carved, or otherwise shaped form comprises two holes 34H for receiving a fastener, and a concave, preferably metal, surface. The attachment has a depth of curvature of approximately one-half of the height of the attachment. Fastening devices serve to operably connect the individual components of the system, and can be any combination of appropriately sized bolts, screws, pins, or pegs. The sizes of these fastening devices should be sized appropriately to the size of the corresponding receptable, void, or hole.

an open columnar member, for receiving a handle, disposed on and fixed to the first surface of the metallic plate;
wherein the metallic plate has sides of equal length forming a square outline and the open columnar member has a height that is greater than the length of the metallic plate sides.

2. The tamp of claim 1, wherein the ratio of the height of the hollow shaft to the length of the tamp face sides is about 1.4:1.

3. The tamp of claim 1, wherein the second surface is planar.

4. The tamp of claim 1, further comprising multiple support members disposed on and extending from the first surface of the metallic plate to the open columnar member.

5. The tamp of claim 4, wherein the multiple support members are fins.

6. The tamp of claim 5, wherein the fins are disposed on and extend from the first surface of the metallic plate to the open columnar member, wherein an edge of each fin is disposed relative to the shaft at an angle.

7. The tamp of claim 6, wherein each fin is triangular, and an edge of each fin is disposed relative to the shaft at an angle of 45 degrees or less.

8. The tamp of claim 5, wherein each fin has a semi-circular cut out in the fin.

9. The tamp of claim 5, wherein the metallic plate, hollow shaft, and multiple support fins are made of the same material.

10. The tamp of claim 9, wherein the material is steel and the metallic plate has a thickness ranging from 0.1 inch to 0.5 inches.

11. The tamp of claim 1 further comprising a handle of wood disposed in the shaft, which handle is removable.

12. A tamp comprising:

a steel plate with an upper surface and a lower flat planar tamp face;
a hollow shaft, for receiving a handle, extending upwardly and perpendicularly from the upper surface of the steel plate and away from the lower flat planar tamp face; and
multiple support fins in communication with both the upper surface of the steel plate and the hollow shaft, wherein an edge of each fin is disposed relative to the shaft at an angle of 45 degrees or less.

13. The tamp of claim 12, wherein the lower flat planar tamp face has sides of equal length forming a square outline and the hollow shaft has a height that is greater than the length of one of the tamp face sides.

14. The tamp of claim 13, wherein the ratio of the height of the hollow shaft to the length of one of the tamp face sides is in the range of 1.2:1 to 2.3:1.

15. The tamp of claim 14, wherein the ratio of the height of the hollow shaft to the length of one of the tamp face sides is about 1.4:1.

16. The tamp of claim 15, wherein the shaft has a height of 11 inches and the sides of the lower flat planar tamp face each have a length of 8 inches.

17. The tamp of claim 12, further comprising a handle of wood disposed in the shaft, which handle is removable.

18. The tamp of claim 17, wherein a portion of the handle and the hollow shaft have a square cross section.

19. The tamp of claim 12, wherein each fin is triangular and has a semi-circular cut out in a side of the fin.

20. A method of using the tamp of claim 1 comprising repeatedly pressing the lower flat planar tamp face against a ground surface to compact the soil with a downward force.
