Description

FIELD OF THE INVENTION

The present invention relates generally to a form connector for use in connecting forms to develop a form structure into which concrete can be poured to construct a sidewalk, driveway or the like. More particularly, the present application involves a form connector that allows the connected forms to ascend or descend a hill or other sloped surface.

BACKGROUND

Concrete is commonly used in the construction of structures such as sidewalks, driveways and buildings. After cement, aggregate and water are appropriately mixed, the resulting wet mix is generally poured into a form structure that is used to hold the mix into a desired shape while drying. The upper surface of the concrete can be compacted and leveled while in the form structure in order to be both strengthened and shaped. Surfaces of the concrete can then be treated to achieve a desired aesthetic appearance and the form structure can be removed once the concrete has set.

The form structure can be made by a series of interconnected forms. In the construction industry it is common to use forms made of lumber. For instance, 2×4s or 1×4s may be used although it is known to use forms made of other types of material such as metal. The forms are generally elongated members and are arranged in series with one another so as to form a desired frame into which the concrete may be poured. As construction jobs typically vary from site to site, the use of lumber forms is advantageous in that the forms can be quickly and easily cut to various lengths as needed. As the forms are generally elongated members, the forms can be bent or curved over their length to result in a desired shape.

Once the forms have been laid out into a form structure, they are commonly attached to one another through use of an additional, smaller piece of lumber. Here, the ends of adjoining forms are abutted against one another and the additional, smaller piece of lumber is placed against both forms on the side opposite that which will engage the poured concrete. This connecting piece of lumber is then nailed to the sides of the abutting forms in order to result in the abutting forms being connected to one another. Stakes can likewise be driven into the sides of the forms opposite that which contact the concrete in order to reinforce the resulting form structure as the interior of the form structure is subsequently filled with concrete.

The form structure is removed after drying of the poured concrete. In order to reduce waste and save on cost of subsequent construction projects, the forms are saved for future use. In order to remove the forms from the dried concrete, the connecting piece is disengaged from abutting forms. This disengagement is typically done in the fastest manner possible which involves tearing the connecting piece off of the forms. As can be imagined, the forms are susceptible to being damaged when the connecting piece is forcibly removed. The forms thus become damaged over time which leads to the forms being discarded and hence results in an increase in the cost of construction.

Connectors for use in attaching sequential forms that do not involve driving nails into the forms are known. These types of connectors are generally made of metal and have resilient members that give when the ends of sequential forms are forced into the connector. The resilient members apply a holding force to the forms in order to retain the forms in a desired position. Although these types of connectors work well for their intended purpose, they are not capable of holding forms together that slope upwards over the crown of a hill or slope downwards across a valley. These types of connectors hold forms in such a way that offers no versatility in angling the forms upwards or downwards when sloped form structures are needed. As such, there remains room for variation and improvement within the art.

DETAILED DESCRIPTION OF REPRESENTATIVE EMBODIMENTS

Reference will now be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, and not meant as a limitation of the invention. For example, features illustrated or described as part of one embodiment can be used with another embodiment to yield still a third embodiment. It is intended that the present invention include these and other modifications and variations.

It is to be understood that the ranges mentioned herein include all ranges located within the prescribed range. As such, all ranges mentioned herein include all sub-ranges included in the mentioned ranges. For instance, a range from 100-200 also includes ranges from 110-150, 170-190, and 153-162. Further, all limits mentioned herein include all other limits included in the mentioned limits. For instance, a limit of up to 7 also includes a limit of up to 5, up to 3, and up to 4.5.

The present invention provides for a form connector 10 used to connect adjacent forms 12 and 14 when building a form structure 66 in constructing walkways, driveways and other concrete structures. The form connector 10 allows adjacent forms 12 and 14 to be arranged next to one another so that their top surfaces 54 and 56 are not parallel to one another. This feature may be advantageous when the forms 12 and 14 are located on a surface that is inclined that has one or more peaks and valleys.

FIGS. 1 through 4 show a form connector 10 in accordance with one exemplary embodiment of the present invention. The form connector 10 includes a frame 16 that has a top wall 18 from which a pair of side walls 20 and 22 extend. The frame 16 has ends 24 and 26 located on opposite sides that are open. As can be seen, the interior 50 and bottom 32 of frame 16 are open from end 24 to end 26. In this regard, frame 16 is channel shaped. However, it is to be understood that frame 16 can be variously configured in other embodiments and need not have walls 18, 20 or 22 and need not be channel shaped with open interior 50 and/or bottom 32. For example, the frame 16 may have an I-beam shape, elliptical shape, or an L-bracket shape in accordance with various exemplary embodiments of the present invention.

The top wall 18 has a surface 58 that faces the interior 50 of frame 16. In addition, side walls 20 and 22 also have surfaces 60 and 62 that face the interior 50 of frame 16. The side walls 20 and 22 can be arranged so that surfaces 60 and 62 are parallel to one another and are each oriented at a 90° angle to surface 58 of top wall 18. Although the surfaces 60 and 62 can be set at any distance to one another, they are spaced at ⅞^th of an inch in the embodiment shown. Other arrangements are possible in which the side walls 20 and 22 are angled with respect to top wall 18 so that surfaces 60 and 62 are oriented at an angle up to 110° to surface 58. In further exemplary embodiments, the side walls 20 and 22 are oriented at different angles to the top wall 18 so that surfaces 60 and 62 are likewise oriented at different angles to surface 58. Top wall 18 may be integrally formed with side walls 20 and 22 or may be a separate component that is attached thereto through means such as welding or mechanical fasteners. In accordance with one method of production, a flat metal sheet of 16 gauge steel is twice bent in order to form the top wall 18 and side walls 20 and 22.

A first leg 34 extends from the bottom of side wall 20. The first leg 34 is an L-shaped member as shown in FIGS. 1-4. A second leg 40 also extends from side wall 20 and is spaced from the first leg 34. Although shown as an L-shaped member, the second leg 40 can be variously shaped in accordance with other exemplary embodiments of the present invention. It is also to be understood that the legs 34 and 40 can have the same shape as one another or may have a different shape from one another in other exemplary embodiments. Further, although described as extending from side wall 20, the legs 34 and 40 may each extend from side wall 22 or may extend from both side wall 20 and side wall 22 in various embodiments. Further, the form connector 10 can be configured so that the legs 34 and 40 do not extend from the side walls 20 and 22 in accordance with other exemplary embodiments of the present invention. As shown in FIGS. 1-4, the legs 34 and 40 are integrally formed with frame 16. Other embodiments exist in which the legs 34 and 40 are separate components that are attached to side wall 20 through various means such as adhesion, welding, mechanical fasteners, sonic welding or brazing.

Top wall 18 of frame 16 has a length 28. Additionally, side walls 20 and 22 have lengths 30 and 31 that are the same as length 28 in the exemplary embodiment shown. However, it is to be understood that other embodiments exist in which length 28 is greater or less than the lengths 30 and 31 of side walls 20 and 22. Further embodiments are also possible in which the length 30 of side wall 20 is different than the length 31 of side wall 22. In accordance with one exemplary embodiment, the lengths 28, 30 and 31 are all 8 inches. However, in other embodiments the lengths 28, 30 and 31 may be up to 24 inches. The first leg 34 is located along the length 30 of side wall 20 so as to be a distance 46 from the end 24. In a similar manner, second leg 40 is located along the length 30 of side wall 20 a distance 48 from end 26. Distances 46 and 48 may be the same as one another or may be different in various exemplary embodiments. In accordance with one exemplary embodiment of the present invention, distance 46 is ½ inch and distance 48 is ½ inch. However, it is to be understood that other embodiments are possible in which distances 46 and 48 are up to 3 inches. Side walls 20 and 22 each have a height that is generally oriented at 90° to their lengths 30 and 31. The heights of side walls 20 and 22 are 2.75 inches in the embodiment shown but may be up to 12 inches in other embodiments.

As shown, a space 52 is defined between the first leg 34 and the second leg 40. Space 52 may extend a distance of 3 inches in a direction parallel to the length 30 of side wall 20. In other configurations, the length of space 52 in the direction parallel to length 30 is up to 6 inches. Space 52 can be completely open so that nothing is present across the width of space 52 which extends from opposite ends of legs 34 and 40 in a direction perpendicular to the length 30 of side wall 20.

First leg 34 has a first surface 36 that is oriented so as to face the bottom 32 of frame 16. As shown, first surface 36 is planar in shape but can be variously shaped in other embodiments. The first surface 36 has a length 38 that extends in a direction generally parallel to the direction of length 30 of side wall 20. In accordance with one embodiment of the invention, length 38 is 2 inches. Other embodiments are possible in which length 38 is up to 6 inches. The second leg 40 has a second surface 42 that is likewise oriented in facing relationship with bottom 32 of frame 16. Although shown as being planar in shape, the second surface 42 can alternatively be contoured. The second surface 42 has a length 44 that extends generally parallel to the length 30 of side wall 20. As with length 38, length 44 is 2 inches in the exemplary embodiment shown but may be up to 6 inches in other embodiments. Although shown as being the same, the lengths 38 and 44 of surfaces 36 and 42 may be different in accordance with various exemplary embodiments. For example, length 38 may be 1 inch and length 44 may be 4 inches in one configuration of the form connector 10. The legs 34 and 40 are L-shaped in the embodiment shown so that the surfaces 36 and 42 are oriented at a right angle to the vertically extending portions of the legs 34 and 40 contiguous with the side wall 20. Other embodiments are possible in which the surfaces 36 and 42 are not oriented at 90° but are instead oriented at various angles to the upwardly extending portions of legs 34 and 40. The width or depth of surfaces 36 and 42, which extend at a generally 90° angle to the direction of length 30 of side wall 20, may be 1 inch in certain exemplary embodiments. The width or depth of surfaces 36 and 42 may be from ¼ inch to 6 inches in accordance with other exemplary embodiments. It is to be understood that although shown in relation to planar surfaces 36 and 42, lengths 38 and 44 can be associated with variously shaped surfaces 36 and 42. In this regard, surfaces 36 and 42 can be convex, concave, sinusoidal, or shaped otherwise. Here, the lengths 38 and 44 are still present and represent the lengths of the surfaces 36 and 42 in the direction generally parallel to the length 30 of side wall 20.

The form connector 10 defines an empty space 64. Empty space 64 has a height that extends from the bottom 32 of frame 16 to the surfaces 36 and 42 of the legs 34 and 40. In accordance with one exemplary embodiment, the height of empty space 64 is 1 inch. However, other embodiments are possible in which the height of empty space 64 is from ¼ inch to 6 inches. The empty space 64 has a length that extends the same distance as the length 30 of side wall 22. The length of empty space 64 is 8 inches in the displayed embodiment but may be from 3 inches to 18 inches in accordance with other exemplary embodiments. Empty space 64 is aligned with both the space 52 between legs 34 and 40 and also with the open bottom 32 of frame 16 so that a surface 58 of top wall 18 is visible as shown in FIG. 4. As such, empty space 64 has a generally rectangular shape but can be variously shaped in accordance with other exemplary embodiments.

FIG. 5 shows the form connector 10 as previously described in relation to FIGS. 1-4 being used to connect a pair of forms 12 and 14. Forms 12 and 14 can be made of lumber 2×4s or 1×4s. However, it is to be understood that form 12 and/or form 14 can be made of metal, plastic or a composite material in accordance with various exemplary embodiments. An end of the forms 12 and 14 are inserted into the interior 50 of frame 16 and also into the previously empty space 64 defined by the frame 16 and legs 34 and 40. The frame 16 and legs 34 and 40 can be sized to accept forms 12 and 14 of a certain size so that the ends of forms 12 and 14 are frictionally retained by the form connector 10. However, it is to be understood that the form connector 10 can still function to retain forms 12 and 14 even if the forms 12 and 14 are loosely retained in the form connector 10. As shown in FIG. 5, the ends of forms 12 and 14 abut one another so that they make contact at some point within the form connector 10. The point of contact of forms 12 and 14 may be at the midpoint of the length 30 of side wall 20 or may be at any other location along length 30. The bottom of form 12 contacts the second surface 42 of second leg 40, and the bottom of form 14 contacts the first surface 36 of the first leg 34. Both form 12 and form 14 contact the surfaces 58, 60 and 62 of the top wall 18 and side walls 20 and 22 of frame 16. However, other arrangements are possible in which one or both of the forms 12 and 14 do or do not contact the various surfaces 36, 42, 58, 60 and 62.

The ground 68 shown in FIG. 5 is substantially level. The forms 12 and 14 rest on the ground 68 and are thus generally linearly arranged with respect to one another. The form connector 10 retains both of the forms 12 and 14 and is oriented so that the top wall 18 is located above the forms 12 and 14 and so that the bottoms of legs 34 and 40 are located under forms 12 and 14. The forms 12 and 14 are arranged next to one another so that the top surface 54 of form 12 is parallel with the top surface 56 of form 14. Connection of form 12 and form 14 causes a form structure 66 to be produced that can be used to build driveways, side walks and the like. Stakes and other supporting members can be installed in order to finish or reinforce the form structure 66. The form connector 10 can be arranged with respect to the forms 12 and 14 so that concrete can be poured on either side of the form connector 10. Once the concrete has been poured and has hardened to a sufficient degree, the stakes and then the form structure 66 can be removed from the edge of the concrete. The form structure 66 can be struck or the forms 12 and 14 can otherwise be pulled or forced from the form connector 10. Once disassembled, the forms 12 and 14 along with the form connector 10 can be reused at a future job site.

The configuration of the form connector 10 may be helpful in allowing forms 12 and 14 to be connected to one another when the ground 68 is not level. FIG. 6 shows an exemplary embodiment of the present invention in which a form connector 10 is used to connect forms 12 and 14 at the crown of a hill. The forms 12 and 14 are again retained by the form connector 10 but are oriented at an angle to one another so that the top surface 54 of form 12 is not parallel with the top surface 56 of form 14. The ends of forms 12 and 14 are arranged so that they do not completely contact one another but are instead simply touching at a point or line near their bottom ends thus forming a V-shaped gap in the interior 50 of frame 16. The distance 46 of first leg 34 to end 24 and the distance 48 of second leg 40 to end 26 provide clearance to allow the forms 12 and 14 to be angled in the form connector 10 for utility on uneven ground 68. The resulting form structure 66 can thus be used to construct a driveway, side walk or other surface much in the same manner as previously discussed with respect to the arrangement in FIG. 5. Although shown as being oriented at approximately the same angle with respect to the form connector 10, the forms 12 and 14 can each be at different angles to the form connector 10 if the ground 68 slopes at different angles on opposite sides of the elevated mound or crown. Forms 12 and 14 can have a height less than the distances from surfaces 36 and 42 to surface 58 to allow for the forms 12 and 14 to be angled in the form connector 10. Alternatively, one or both of the forms 12 and 14 can have a height the same as that from surfaces 36 and 42 to surface 58 but can have force from a user applied thereto in order to be oriented into an angular configuration in form connector 10.

FIG. 7 shows another exemplary embodiment of the form connector 10. Here, the ground 68 forms a valley instead of a crown as previously described in relation to FIG. 6. The form connector 10 is configured to allow the forms 12 and 14 to be connected and arranged with respect to one another so that the resulting form structure 66 can ascend or descent uneven ground 68 to help build a driveway, side walk or other structure that has a valley. As shown, the top surface 54 of form 12 is not parallel with the top surface 56 of form 14. The tops of the ends of forms 12 and 14 meet at a point or line thus forming an inverted V-shaped gap between the forms 12 and 14. The forms 12 and 14 contact and are at least partially retained by the surfaces 60 and 62 of the side walls 20 and 22. Due to the angled orientation of forms 12 and 14, the surfaces 36 and 42 of legs 34 and 40 may or may not be contacted. The space 52 between the legs 34 and 40 provides clearance for the forms 12 and 14 thus allowing the angular orientation shown. As the forms 12 and 14 are oriented, they do not completely fill the interior 50 of frame 16 and the empty space 64 in contrast to the orientation of forms 12 and 14 as discussed in relation to FIG. 5. The point of contact between forms 12 and 14 occurs at approximately the midpoint of the length 30 of the side wall 20. Other arrangements exist in which the point of contact of forms 12 and 14 takes place at locations besides the midpoint of length 30. Further, although shown as having generally the same angular orientation with respect to the form connector 10, the forms 12 and 14 can each be oriented at a different angle with respect to the form connector 10. This may be the case in which the ground 68 on either side of the valley rises at a different angle.

The form connector 10 can also be used to connect forms 12 and 14 that themselves do not contact one another. FIG. 8 shows one such arrangement in which the forms 12 and 14 are retained by form connector 10 to create a form structure 66 located at the crown of a hill. The ends of forms 12 and 14 are located in the form connector 10 and contact surfaces 36, 42, 58, 60 and 62 but do not completely fill the interior 50 and the empty space 64. Again, the offsetting of legs 34 and 40 from ends 24 and 26 such that distances 46 and 48 are created provides clearance for the forms 12 and 14 to be angled in the displayed manner. The sloping of ground 68 is more extreme in FIG. 8 than in FIG. 6 and the ends of forms 12 and 14 are located further away from one another in form connector 10 in view of this topography.

As mentioned, the forms 12 and 14 can be made of pieces of 1×4 lumber. Extended pieces of such lumber are capable of curving over their lengths. FIG. 9 is a perspective view of a form structure 66 made by forms 12 and 14 composed of 1×4 lumber. Forms 12 and 14 are connected to one another through use of form connector 10. Forms 12 and 14 are curved about their length so that they each have a vertically oriented axis of curvature. The ability of forms 12 and 14 to curve allows for the resulting form structure 66 to be curved to assist in building driveways and side walks with this resulting shape. In addition to curving about a vertical axis of curvature, the form connector 66 may allow for the forms 12 and 14 to have top surfaces 54 and 56 angled with respect to one another. As such, the resulting form structure 66 enjoys increased versatility during use.

A series of forms may be connected to one another with several form connectors 10 to construct a form structure 66 to be used over ground 68 with a varying topography. FIG. 10 shows one such form structure 66 used on ground 68 that has various crowns, valleys and inclines. Although described as being used in conjunction with crowns and valleys, the form connector 10 can be used to connect forms 12 and 14 to one another that are not located on distinct crowns or valleys but are instead located on portions of the ground 68 that slope at different angles to one another. In this regard, the forms 12 and 14 will be oriented at different angles with respect to the form connector 10. Certain ones of adjacent forms 12 and 14 may be located on ground 68 that does not change angularly. Here, the forms 12 and 14 can be connected in a linear fashion as previously described with reference to FIG. 5. The configuration of form connector 10 may allow adjacent forms 12 and 14 to be connected to one another so that their top surfaces 54 and 56 are not parallel to one another but are instead oriented at an angle to one another.

Although various components of the form connector 10 were described herein as having certain dimensions, it is to be understood that the aforementioned dimensions were only for sake of example and are not limiting to the present invention. The present invention includes various form connectors 10 that may or may not have components with the previously discussed dimensions.

While the present invention has been described in connection with certain preferred embodiments, it is to be understood that the subject matter encompassed by way of the present invention is not to be limited to those specific embodiments. On the contrary, it is intended for the subject matter of the invention to include all alternatives, modifications and equivalents as can be included within the spirit and scope of the following claims.
