SUMMARY OF THE INVENTION

It is an object of the present invention to obviate or mitigate at least one disadvantage of previous amusement devices.

In a first aspect, the present invention provides a construction set including: a plurality of magnetized rotary construction pieces and a journal board adapted for receiving the magnetized rotary construction pieces within a playing area of numerous closely-spaced receptacle pivot locations; the magnetized rotary construction pieces each including a body portion and a centralized axle projection; the axle projection adapted to removably-fit on the journal board and rotate within the receptacle pivot locations of the journal board; the body portion further including magnetized elements arranged in a circular pattern with numerous locations of outward magnetic polarity around the periphery of the rotary construction pieces; and magnetized elements adapted for providing for rotational magnetic coupling when the magnetized rotary construction pieces are placed in proximity to each other on the journal board.

In further aspect, the present invention provides a construction set including; a magnetized drive ring, a plurality of magnetized rotary construction pieces and a journal board including a journal array adapted for receiving the magnetized rotary construction pieces within a playing area of numerous receptacle pivot locations; the journal board further including a substantially annular ring supporting means adapted for providing the pivoting of the magnetized drive ring around the periphery of the journal hole array; the magnetized rotary construction pieces each including a body portion and a centralized axle; the axle adapted to removably-fit on the journal board and rotate within the receptacle pivot locations of the journal board; the body portion further including a circular pattern of magnetized elements adapted for rotational magnetic coupling when the magnetized rotary construction pieces are closely spaced apart on the journal board; the magnetized drive ring including a ring-shaped body characterized by a major and minor diameter and a rotation drive means; the magnetized drive ring adapted to be rotationally supported by the annular ring supporting means of the journal board; and the ring-shaped body including a circular pattern of magnetized elements positioned near the minor diameter and adapted to provide rotational magnetic coupling when the magnetized rotary construction pieces are placed on the journal board within the magnetized drive ring in proximity to the minor diameter of the magnetized drive ring.

Generally speaking, the present invention is an amusement device concerned with a construction toy system of high educational value. The construction type apparatus disclosed provides unique capability for amusement via board design and playing piece structure allowing relative motion between playing pieces. The apparatus is of the type having rotary path-forming playing pieces that can be located in numerous positions on a journal board. Moreover, the playing pieces are removably interfitting and allow the construction of variable paths and design patterns.

The amusement device incorporates magnetism to perform relative rotary motion. A circular pattern of permanent magnets are included in playing pieces to allow numerous magnetically coupled rotary pieces to undergo relative rotation analogous to a gear train.

The invention has multiple formats and applications. A preferred format is a construction system in which a person can employ the playing pieces in numerous patterns and configurations for achieving complete magnetic coupling and simultaneous motion.

An individual may explore numbers patterns and configurations of magnetically coupled rotary playing pieces as curiosity directs in “solitare” play. As playing pieces are removably interfitting with the game board, the rotating disks can be arranged and re-arranged with substantial freedom to form theories and investigate results of pattern formation. For example the device allows the construction of circular patterns, linear patterns, spiral patterns, and patterns which are symmetrical about one or more planes. Depending on placement and configuration the invention allows an individual to also form closed loops where as more than one playing piece of the same “gear train” is linked to the lead gear.

As the invention allows simultaneous motion of a multitude of disks, dynamic visual results can be achieved with greater expression through the deployment of graphical cover plates. These covers can be added and exchanged based on the user's opinion. The plastic cover plates add an extra layer of creative construction and play since the interchanging graphics can give a single pattern a different look and feel and thus a higher level of versatility and personalization is enjoyed in the contest of the construction system.

According to a secondary format, the construction system can be adapted for competitive playing by a number of individuals. In competitive play, players take turns adding rotary playing piece until free space on the board is diminished to the point where adding additional pieces disrupts the magnetic coupling of previously placed rotary pieces. According to this competitive format, the path forming game of this type relies on mental processes and strategy to construct a pattern in maximizing the number of magnetically coupled rotary playing pieces as part of the “gear train”.

In all conceived playing formats, successful execution will depend on mental process such as knowledge of combinations relative to interchangeable gears and being able to visually estimate transverse and diagonal distances between placement locations. Successful placement also depends on an awareness on how distance between playing pieces relates to the magnitude of constructive coupling or interference depending on the properties of the playing pieces such as size and pattern of permanent magnets displaced on rotary playing pieces.

Competitive game play according to the present invention does also enable the use of strategy for proactive placement or rotary playing pieces in the attempt to limit the selection of pivot locations of an opposing opponent and force the outcome of an opponent causing the “gear train” to “lock up” on account of poor placement or limited placement options. Thus it will be come apparent to one skilled in the art that the novel construction system provides an interactive apparatus for exploring the principles of magnetic coupling and relative motion. Such an interactive apparatus is so adapted to be both enjoyable and intellectually stimulating.

In addition providing amusement and various formats for play, the present invention also embodies an education and demonstration device whereby the assembly of magnetically coupled rotary pieces provides the interactive demonstration of a gear train machine mechanism

The invention enables a high degree of interchangeable, variable, or plural distinct playing patterns via the substantially dense array of pivot locations provided for within the journal board array. The closely spaced array of receiving holes enables relatively precise positioning of playing pieces to build an assembly that exhibits relative movement of all magnetically coupled playing pieces via rotation of single driving disk or ring.

Several embodiments are disclosed including a first preferred embodiment in a system designed around a journal board in which a driving disk shaped crank is centrally located. According to this embodiment, playing pieces are placed to extend the “gear train” of magnetically coupled rotary playing pieces such as to provide an “inside-out” playing format.

Other preferred embodiments include those wherein the journal board is circular and a rotational-magnetic ring crank is located to revolve around the outside of the array of journal positions. According to this preferred embodiment, playing pieces are added to extend the “gear train” from the inside of the ring toward the center of the journal hole array such as to provide an “outside-in” playing format. The exterior ring crank comprises a revolving handle which allows easy revolution according to the manipulation of the user.

An added benefit of this preferred configuration, in comparison to other configurations utilizing a central driving gear is that the players can drive the rotary playing pieces to spin at higher speeds enabling them to explore a wider range of visual and magnetic interactive effects with greater ability to alter the dynamics. For example, relative motion between rotary playing pieces caused by magnetic coupling can be overcome by suddenly switching the direction of rotation and rotating at high speed. One or more playing pieces that would normally spin when rotating the driving member at low speed can be caused not to spin at high speed by dynamic manipulation. Furthermore, a player can strategize about the placement of rotary playing pieces such that intended dynamic effects can be deliberately achieved.

To summarize, the construction system according to the present invention is characterized with the following advantages.

The construction system is fun and enjoyable to play and use.

The construction system is intriguing in that it allows a large number of non-touching rotary playing pieces to be magnetically coupled so as rotation of one rotary playing piece causes a great many of other playing pieces to also rotate.

The construction system is highly interactive and allows many variable paths and patterns.

The construction system is visually pleasing and allows one to see the effects of applying customizable graphics to simultaneously spinning playing pieces.

The construction system instructs players of the principles of magnetic coupling and interaction and how variables act to encourage and discourage the rotational coupling.

The construction system instructs players of relative rotary motion analogous to gear trains.

The construction system encourages spatial intelligence in the strategic placement of rotary playing pieces.

The amusement device provides a novel format of play whereas magnetic properties of rotary playing pieces work both productively and counter-productively in the progress of play.

The construction system allows an individual to explore and investigate numerous patterns and configurations as curiosity leads.

The construction system is novel and intriguing in how it allows one to visualize magnetic interaction in a dynamic format.

The construction system is “hands on” in that one can touch and feel the results of configuring and reconfiguring the magnetically coupled apparatus.

Other advantages and benefits may be possible, and it is not necessary to achieve all or any of these benefits or advantages in order to practice the invention as claimed. Therefore, nothing in the forgoing description of the possible or exemplary advantages and benefits can or should be taken as limiting.

DETAILED DESCRIPTION

As utilized herein, terms such as “about”, “approximately”, “substantially” and “near” are intended to allow some leeway in mathematical exactness to account for tolerances that are acceptable in the trade.

Before explaining the present invention in detail, it should be noted that the invention is not limited in its application or use to the details of construction and arrangement of parts illustrated in the accompanying drawings and description. The illustrative embodiments of the invention may be implemented or incorporated in other embodiment, variations and modifications, and may be practices or carried out in various ways. Furthermore, unless otherwise indicated, the terms and expressions employed herein have been chosen for the purpose of describing the illustrative embodiments of the present invention for the convenience of the reader and are not for the purpose of limiting the invention. Further it is understood that any one or more of the following-described embodiments, expressions of embodiments, examples, methods, etc. Can be combined with any one or more of the other following-described embodiments, expressions or embodiments, examples, methods, etc.

Referring to FIGS. 1-6E, a first preferred embodiment of the present invention is shown.

FIG. 1 is a front perspective view of a construction set according to the first preferred embodiment. The construction set includes journal base board 110, rotational-magnetic disk crank 74, and a group of rotary playing pieces 61 comprising several large rotational-magnetic playing pieces 62A, medium rotational-magnetic playing pieces 62B, and small rotational-magnetic playing pieces 62C. Playing pieces 62A, B and C are each provided with graphical face plates 80E, 81E, and 82E respectively.

The base of the apparatus is journal board 110 adapted to receive rotational-magnetic playing pieces 61. Each large, medium and small rotational-magnetic playing pieces 62A, 62B, and 62C comprises a substantially circular disk body 64A, B and C. Handle portion 65A, B and C is a slender projection extend above respective disk bodies for facilitating hand placement on journal base board. Each of the rotational-magnetic playing pieces further comprise shafts portion 66A, B and C respectively centrally projecting below disk bodies 64A, B, and C and are adapted to closely fit within variable journal positions of journal hole array 112 of journal board 110.

Playing pieces are further provided with graphical cover plates 80E, 81E, and 82E adapted to fit on magnetic-rotational playing pieces over handle portions 65A, 65B and 65C respectively.

Journal board 110 comprises journal grid 112 which is an array of holes of sufficient depth to receive shaft portions 66A, B and C of rotational-magnetic playing pieces 62A, B and C. Accordingly, playing pieces 62A, B, and C slip into journal board 110 and are permitted to pivot in numerous pivot locations as provided by journal hole array 112 having a grid comprising a hole pattern. Journal hole array 112 is of sufficient size and hole density to allow numerous pivot locations for rotational-magnetic playing piece 62A, B, and C to be placed in close proximity on journal board 110 such that disk portions 64A, B, and C reside on top surface 114 of journal board 110 without touching each other while also freely pivoting on axis of each respective shaft portion 66A, B, and C. Preferably journal board 110 is made of a low friction plastic material such as Acetal copolymer or PVDF. Another preferred low friction yet dimensionally stable material would be Delrin impregnated with Teflon.

Holes of journal hole array is preferably of maximum area and density for allowing the maximum number of pivot locations within area of journal hole array 112. Accordingly, the preferred spacing between holes is less than 1.5 times the hole diameters. Journal base board 110 is of sufficient thickness to support rotational-magnetic playing piece in magnetically coupled configurations without yielding under the action of magnetically attractive and repulsive forces.

Rotational-magnetic disk crank 74 is provided with revolving handle 75 projecting from the top of disk portion 64 and located near the edge of disk portion 64 for enabling crank operation in initiating rotation of magnetically coupled rotational-magnetic playing pieces 64A, B and C. Preferably, rotational-magnetic disk crank comprises disk portion 64 of larger size than rotational-magnetic playing pieces 61, whereas the larger size helps facilitate the cranking action and enables a larger number of rotational-magnetic playing pieces to be magnetically coupled directly to disk crank 74.

Shown in FIG. 1, one of each large, medium, and small rotational-magnetic playing pieces 62A, B, and C are configured in a spaced apart row along side rotational-magnetic drive crank 74. According to this configuration, rotation drive crank 74 will cause magnetically coupled rotational-magnetic playing pieces 62A, B, and C to rotate with direction of spin alternating from playing piece to playing piece.

Now referring to FIGS. 2A-2E, the preferred construction of small rotational-magnetic playing piece 62C is shown in greater detail along with complementary graphical cover plate 82E. As shown, the small rotational-magnetic playing piece 62C of this preferred embodiment comprises circular disk body 64C having central handle portion 65C projecting above and central shaft portion 66C projecting below.

Shaft portion 66C and handle portion 65C are integral to disk body 64C where as they are all part of a single injection molded component to which rectangular magnets are subsequently installed. Although shaft portion is of a small diameter the required length is sufficiently small to prevent it from being easily damaged a result of applied bending loads. This provides a cost advantage with the ability to mass produce the rotational-magnetic playing pieces with minimum additional material costs other than the costs of the embedded rectangular magnets 69. Alternatively the shaft portion 66C may consist of a metal pin pressed into disk portion 64C. Such a shaft could provide reduced friction and increased stiffness to shaft portion 66C. Above shaft portion 66C disk portion 64C further comprises contoured bottom 71C for reducing the contacting surface area with the journal base board 110 when placed thereon whereas the surface area of bearing surface 72C is much less than the surface area corresponding to contoured bottom 71C.

Disk body 64C further comprises axial slots 68C in which rectangular magnets 69 are housed. Axial slots 68C are arranged in a circular pattern within disk body 64C for accommodating rectangular magnets 69 in a circular pattern near disk parameter 74C. When pressed into axial slots 68C, rectangular magnets 69 are substantially embedded in disk body. Slot recesses 70C remain when the rectangular magnets are fully inserted during manufacturing and can be subsequently filled with adhesive or an interlocking cap so that magnets 69 are completely encapsulated within disk body 64C. However a light interference fit is all that is needed for preventing rectangular magnets 69 from being able to be dislodged from disk body 64C when under magnetic attractive and repulsive loading. Alternatively, rectangular magnets 69 are over molded during manufacturing to provide full encapsulation.

As shown in the sectional view of FIG. 2E, disk body 64C comprises an even number of axial slots 68C for accommodating an even number of rectangular magnets 69 which are arranged as to exhibit a radial outward polarity of which north and south poles alternate. Small rotational-magnetic playing piece 62C comprises 10 rectangular magnets 69 closely spaced around the inside of the disk parameter 73C.

According to this preferred embodiment, centralized handle portion 65C is substantially slender, is sufficiently long to be gripped by hand for easy placement, and is of an oblong cross section. The slenderness of handle portion 65C enables graphical cover plate 82E to be of maximum surface area and the oblong shape facilitates interlocking with central oblong hole 83C of cover piece 82E so that when cover plate 82E is placed on rotational-magnetic playing piece 62C it spins in conjunction with small rotational-magnetic playing piece 62C.

Small graphical cover plate 82E is preferably a removable substrate that can be placed upon rotational-magnetic playing piece 62C or can be exchanged for graphical cover plates of the same size having alternate graphics. For example Small graphical cover plate 85E could be a stamped from a plastic sheet and provided with an adhesive graphics. Alternatively graphical cover plate 82E may comprise a substrate suitable for painted or printed graphics applied directly thereto. Another alternative is for graphical cover plate to a cardboard cutout supplied with the construction set whereas differing supplied cardboard graphical cover plates can be selected from punch-out cardboard sheets of profiles and graphical indication means similar to the various graphical cover plates shown in FIGS. 11A-11E.

Graphical cover plate 82E is characterized as a thin disk with outside diameter 84C and a central oblong hole 83C. Outside diameter 84C is substantially equivalent to diameter associated with disk parameter 73C. Graphics 89E are displaced on top face 85C and optionally also on bottom face 86C. For example, a clockwise spiral graphic similar to that shown may be on the top face while the bottom face may contain a counter-clockwise spiral so that playing pieces may be configured so that you get the same dynamic visual effect for playing pieces rotating both clockwise and counterclockwise.

Now referring to FIGS. 3A-3E, the preferred construction of large rotational-magnetic playing piece 62A is shown in greater detail along with complementary graphical cover plate 80E. As shown, the large rotational-magnetic playing piece 62A of this preferred embodiment comprises circular disk body 64A with central handle portion 65A projecting above and central shaft portion 66A projecting below. In like manner to small rotational-magnetic playing piece 62C of FIGS. 2A-2E disk body 64A comprises contoured bottom 71A, bearing surface 72A, and axial slots 68A for accommodating rectangular magnets 69. However disk body 64A of large rotational-magnetic playing piece 62A is characterized with a disk parameter 73A significantly larger than that of small playing piece 62C of FIGS. 2A-2E and is configured with a larger number of axial slots 68A to receive a larger number of rectangular magnets 69 arranged in a circular pattern of alternating radial north and south poles. In this case, disk body 64A houses sixteen rectangular magnets as compared to ten rectangular magnets embedded in disk body 64C of small rotational-magnetic playing piece 62C.

Also similar to small rotational-magnetic playing piece 62C, centralized handle portion 65A is substantially slender and of an oblong cross-section. This enables graphical cover plate 80E to be of maximum surface area and the oblong shape facilitates interlocking with central oblong hole 83A of cover piece 80E so that, when cover plate 80E is placed on rotational-magnetic playing piece 62A, it spins in conjunction with large rotational-magnetic playing piece 62A.

Now referring to FIGS. 4A-4E, the preferred construction of rotational-magnetic disk crank 74 is shown in greater detail. Unlike rotational-magnetic playing pieces 62A, B and C, rotational-magnetic disk crank 74 does not comprise a central slender handle portion and is not provided with a complementary removable cover plate. Rather disk portion 64 of rotational-magnetic disk crank comprises an affixed revolving handle 75 projecting up along the side of disk portion 64 near disk parameter 73. Preferably rotational-magnetic disk crank 74 is of larger size than rotational-magnetic playing piece 62A, B and C and revolving handle 75 is of maximum offset with respect to centralized shaft portion 66 for facilitating convenient hand operation in driving rotational-magnetic disk crank 74.

Revolving handle 75 comprises handle base 76 affixed to disk body 64. Handle sleeve 78 is retained on outside of handle base 76 and is adapted to freely rotate thereon so that a person may freely apply a cranking action to rotational-magnetic disk crank 74 whereas magnetic interaction between rotary playing pieces and inertia of playing pieces are the significant counteracting forces when initiating rotation of playing pieces.

Rotational-magnetic disk crank 74 further comprises contoured bottom 71 for providing a bearing surface 72 of minimal yet adequate surface area for contacting journal board when shaft portion 66 is inserted into a pivot location within journal array 112.

Graphical indication means is located on top surface 67 of disk body 64 and preferably includes visual indication means to indicate polarity of internal rectangular magnets embedded within. Preferably graphical indication is provided by an adhesive decal or is printed directly on the substrate that comprises disk portion 64.

Similar to the preferred embodiment of playing pieces 62A, B, and C, disk portion 64 of rotational-magnetic disk crank 74 comprises axial slots 68 for embedding rectangular magnets 69. Preferably, subsequent to insertion of rectangular magnets 69, the slot recesses 70 would be filled with adhesive or sealed in some other manner known to those skilled in the art.

As shown in FIG. 4E, rotational-magnetic disk crank 74 comprises an even number of rectangular magnets 69 housed in a circular pattern of axial slots 68 which is larger in number than large medium and small rotational-magnetic playing piece 62A, B, and C. According to this preferred embodiment rotational-magnetic disk crank 74 comprises twenty rectangular magnets 69 of alternating radial polarity arranged near disk parameter 73.

It should be understood that the rotary playing pieces may be injection molded parts adapted to receive rectangular magnets 69. Preferably, strong rare earth NdFeB permanent magnets are utilized which are composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B). Although parameters 73A, B, and C are shown as round the actual shape of disk body 64A, B and C may be a polygon or another non-circular shape within the scope of the invention. Moreover, the magnets may be other than the rectangular magnets 69 as shown.

Although according the preferred embodiment shown magnetized elements are discrete magnets (i.e., rectangular magnets 69) displaced in axial slots in circular configuration arranged to provide alternating outward polarity, it should be readily understood as within the scope of the invention that magnetization can alternatively be provided by magnetic strip wrapped around the parameter of disk bodies adapted for providing substantially equivalent functionality. It is know to those practiced in the art that multi-pole magnetic strip can be manufactured with a specified width, thickness and length whereas the magnetic strip exhibits a fixed number evenly distributed number of magnetic poles per unit length. For example, according to the invention, magnetic strip that is 0.100 inch thick, 0.250 inch wide and has four poles per inch can be utilized for providing substantially equivalent performance.

Although magnetized elements according to an embodiment utilizing magnetic strip might require a greater volume of magnetic material to provide an equivalent magnetic field whereas a greater width or thickness as compared as to discrete magnets would be required, magnetic strip would provide a cost savings to the extent that cost attributed to magnetic strip as the magnetized elements would be ⅕ to 1/10 the associated costs of using discrete magnets.

In addition to cost savings pertaining to the magnetic material, magnetic strip would also provide improved manufacturability of the device components as compared to utilizing costly discrete magnets which much be precisely accommodated within slots in disk bodies. According to an alternative embodiment utilizing magnetic strip as the magnetization means, the strip can be wrapped around and secured to disk bodies with the use of adhesive and preferably with additional means of securing the strip such as providing for a two-part disk body having a plug and socket type interface for fully encasing the magnetic strip. Such a configuration would likely be characterized with increased product safety.

Referring to FIGS. 5A-5B, rotational-magnetic disk crank 74 is show in proximity to small rotational-magnetic playing piece 62C as if they were placed on a journal base board according to the present invention. As is typical with placement on a journal base board these figures show rotational-magnetic disk crank 74 and small rotational-magnetic playing piece 62C are aligned in a manner whereas shaft portion 72 and 72C are parallel and bearing surfaces 72 and 72C coincident to the same plane.

Referring to FIG. 5C, a section view is shown along a line through disk bodies 64 and 64C of rotational-magnetic disk crank 74 and small rotational-magnetic playing piece 62C respectively. When placed in proximity on a journal board, rotational-magnetic disk crank 74 and small rotational-magnetic playing piece 62C are magnetically coupled so that alternating north and south poles provided by radial magnets 69 cause rotation of small rotational-magnetic playing piece 62C when rotational-magnetic disk crank 74 is rotated. This is facilitated by both the attraction of unlike poles and the repulsion of like poles between proximally located disk bodies.

Circular magnetic pitch P74 of rotational-magnetic disk crank 74 and circular pitch P62C of rotational-magnetic playing piece 62C are substantially equivalent according to the invention as needed for effective coupling between various sized playing pieces. Thus all rotational-magnetic construction pieces including disk crank 74 and large, medium and small rotational-magnetic construction pieces 62A, B, and C have a substantially equivalent circular pitch for providing interchangeability whereas all rotational-magnetic construction pieces can be effectively coupled together.

In this preferred embodiment, variables associated with magnetic coupling are pitch diameters D74D and D62D working depth Dw and pitch point P. Magnetic coupling allows these variables to change depending on proximity of one playing piece to another. This a principal advantage of the invention as compared to other rotational construction type systems relying on mechanical interlocking such as those involving toothed mechanical gears.

According to the invention, Dw can be very small or very large and still provide magnetic coupling between rotational-magnetic disk crank 74 and rotational-magnetic playing piece 62C. However as working depth Dw increases as a result of further apart spacing, the strength of magnetic coupling decreases. The maximum working depth Dw is also influenced by the proximity of other nearby rotational-magnetic playing pieces. This variable is important in constructing various configurations and patterns because proximity can encourage magnetic coupling or cause counter-productive interaction. Thus strategy and intuition is required for achieving relative motion of all rotary construction pieces together such that when rotational-magnetic disk crank is cranked all other rotational-magnetic playing piece 62A, B and C also spin.

Referring to FIGS. 6A-6D, the first preferred embodiment of the present invention is illustrated whereas a row of rotational-magnetic playing piece 62A, B and C along with rotational-magnetic disk crank 74 are placed on rectangular journal board 110 along a central row of journal hole array 112. Bearing surfaces of respective rotational-magnetic playing piece rest on top surface 114 of journal board 110 so that all internal magnets are approximately held at the same elevation. Preferably, shaft portions 72, 72A, B, and C of rotational-magnetic playing pieces do not extend beyond bottom surface 115 when placed within journal board 110. Rubber feet 116 are provide under journal board 110 to apply grip to journal board when a player is actuating rotational-magnetic disk crank 74.

Although rotational-magnetic playing pieces do not physically touch each other when placed in proximity on journal board array 112 the invention utilizes magnetic coupling such that manual rotation of one rotational-magnetic disk crank 74 will cause all magnetically coupled playing pieces 62A, B and C to rotate. Several parameters influence magnetic coupling and the ability to build a path of closely placed rotational-magnetic playing piece 62A, B and C wherein all rotate in response to the manual rotation of a rotational-magnetic disk crank 74. These parameters include but are not limited to differences in radial pitch and size and distance between placed playing pieces.

As indicated by shading of graphical cover plates shown in FIG. 6A and the magnetic polarities indicated in the section views of FIG. 6C and 6D, rotational-magnetic playing piece 62A, B, and C are magnetically coupled to rotational-magnetic disk crank 74 in radial orientations wherein opposite poles are aligned at regions of adjacency. Rotational-magnetic playing pieces can be said to be meshed whereas both attractive and repulsive forces work in regions of proximity to ensure relative motion between magnetically coupled rotational playing pieces. Again magnetic coupling can be explained by attraction of proximal magnetic north and south poles and by repulsion of proximal magnetic north and north or magnetic south and south poles.

Although shown in a straight line, numerous configurations of magnetically coupled rotary construction pieces are possible by strategic placement of playing pieces 62A, B and C within journal hole array 112. Although rotational-magnetic playing piece 62A, B and C vary in size and number of radial magnets 69 each rotational-magnetic playing piece 62A, B and C comprises a circular pattern of an even number of spaced apart rectangular magnets 69 that are characterized with a substantially equivalent radial spacing. Thus large rotational-magnetic playing piece 62A, medium rotational-magnetic playing piece 62B and small rotational-magnetic playing piece 62C are each characterized with a radial pitch within an acceptable range to facilitate effective magnetic coupling.

The size of each disk portion corresponding to the various sized rotational-magnetic playing pieces 62A, B and C is preferably determined according to a numerical relationship corresponding to the spacing between pivot point locations along journal hole array 112. For example, according to the preferred embodiment of FIGS. 1-6D, diameters of small, medium, and large rotational-magnetic playing piece 62C, B and A and rotational-magnetic disk crank 74 are approximately ⅞″, 1⅛″, 1⅜″, and 1⅝″ respectively whereas spacing between pivot locations of journal hole array 112 is ⅛″. This sizing and space relationship allows substantially precise placement of rotational-magnetic playing pieces in close proximity along a line.

According to the invention, when journal hole array 112 is populated with rotational-magnetic playing piece 62A, B and C, it becomes increasingly difficult to construct a fully rotating train of rotational-magnetic playing pieces 62A, B and C, due to the unintended interference (counter-productive interaction) of previously placed rotational-magnetic playing pieces 62A, B and C which acts to lock up portions of the path formed. As space becomes less available along journal hole array 112, a player becomes more limited in availability of successful positions for productive placement of rotational-magnetic playing piece 62A, B and C and it becomes more challenging to successfully extend the number of magnetically coupled playing pieces that rotate upon the manual rotation of rotational-magnetic disk crank 74.

A preferred format of play within the scope of the present invention is the ability to form patterns and form numerous variable paths of magnetically coupled rotating elements. Thus the objective of one or more players is to incrementally add rotary construction pieces to journal hole array that form a magnetically coupled path from rotational-magnetic disk crank 74 whereas rotation of rotational-magnetic ring crank will cause all placed rotary construction pieces to also rotate and experience relative motion. Such patterns can take on numbers shapes and depict things such as robots or other objects. Patterns may have various degrees of symmetry and may have triangular, rectangular or circular paths.

An alternative format of play of the present invention is a construction type path-forming challenge to maximize the number of magnetically coupled rotary construction pieces that can be attached to the “gear train” before a lock up occurs that prevents one or more rotary construction pieces from rotating. According to this format, a multi-player game would instruct players to take turns adding rotary construction pieces. The player that causes magnetic lockup of one or more rotary playing through counter-productive placement of rotary construction pieces looses the game. Thus loss would be incurred either through poor placement strategy or a lack of placement options due to congestion of rotary construction pieces covering most of the journal board. Thus an enjoyable and intellectually demanding method of play is to maximize the number of rotary construction pieces added to the “gear train” before “lock-up” is encountered.

Thus it will be come apparent to one skilled in the art that the present invention provides an interactive apparatus for exploring the principles of magnetic coupling and relative motion. Numerous other formats are also envisioned including the goal to produce specific patterns or to link a rotational-magnetic playing piece on one position on the journal board to one or more rotational-magnetic pieces at a distant spaced apart location. Such an interactive apparatus is so adapted to be both enjoyable and intellectually stimulating.

Referring to FIGS. 7-8B, a second preferred embodiment of a construction set according to present invention is shown wherein an octagon-shaped journal base board 120 is provided. Journal base board 120 comprises a larger surface area and increased number of pivot locations for enabling the formation of numerous patterns from extended paths of magnetically coupled playing pieces. Examples of such pattern of numerous large, medium and small rotational-magnetic playing pieces 62A, B and C are shown in FIG. 7 and in FIGS. 8A-8B.

Although not necessary to the embodiment, both configurations rely on centrally located rotational-magnetic disk crank 74 to initiate rotation of all magnetically coupled playing pieces. In addition to having differing patterns FIG. 7 and FIGS. 8A-8B also show the application of differing graphical cover plates as facilitated by the invention whereas cover plates 80, 81, and 82 are removable and differing graphical indication means can be exchanged.

An interchangeable construction apparatus of this size is provided to facilitate play whereas a large number of rotational-magnetic playing pieces can be magnetically coupled for producing relative motion resultant from the hand rotation of a single drive crank. Numerous path formations and patterns can be constructed as journal hole array 122 is of sufficient size and density for adding a substantial number of rotational-magnetic playing piece providing extended play for making the construction device more enjoyable and captivating for the players.

Referring to FIGS. 9A-10E, a third preferred embodiment of the amusement construction apparatus according to present invention is shown whereas a circular journal board 30 is adapted to receive rotational-magnetic ring crank 89 for facilitating rotation of rotational-magnetic playing pieces 62A, B, and C located within the interior along journal hole array 31. Rotational-magnetic playing pieces 62A, B and C are identical to the previous disclosed embodiments. As opposed to the previous embodiments of centralized rotational-magnetic disk crank 74 from which other rotational-magnetic playing piece are generally placed near the center of the journal hole array toward the outside, this third preferred embodiment enables path formation from the outer boundary of journal hole array 31 generally toward the center. Thus rotational-magnetic ring crank 89, in conjunction with journal board 30, provides the means for the unique outside-in format of play.

Referring to FIGS. 9A-9C rotational-magnetic playing pieces 62A, B, and C are placed in several clusters which form small paths linked to the inner parameter 93 of rotational-magnetic ring crank 89. Accordingly, the rotational-magnetic playing pieces 62A, B, and C will spin with rotation of rotational-magnetic ring crank 89 by actuating rotational-magnetic ring crank 89.

Circular journal board 30 is characterized with a top surface 35 and bottom surface 36. Annular slot 32 extends below top surface 35 and is of sufficient width to accommodate ring body 90 of rotational-magnetic ring crank 89. Annular slot 32 thus provides a means of concentrically locating ring body 89 around journal hole array 31 and maintaining a substantially fixed axis of rotation for rotational-magnetic ring crank 89. Journal board 30 further comprises feet 34 which extend from bottom surface 36 and provide support to journal board 30. Feet 34 preferably are rubber or a gripping material to counteract torque applied by rotational-magnetic ring crank 89 during play. While feet 34 are shown as three, a larger number of feet are likely preferred to prevent tilting of journal board 30 during manipulation of rotational-magnetic ring crank 89.

Ring crank 89 comprises ring body 90 having top face 92, bottom face (not shown), inside face 93 and outside face 94. Internal magnets 96 are displaced in a circular pattern near inside face 93. Circular pattern of internal magnets 96 are characterized with an alternating radial polarity whereas alternating north and south poles are oriented inward toward journal hole array 31 to facilitate magnetic coupling with rotational-magnetic playing pieces 62A, B and C. Internal magnets 96 are also characterized with a substantially equivalent circular pitch as radial magnets 23 or rotational-magnetic playing pieces 62A, B and C. Thus rotational-magnetic ring crank provides inward magnetic coupling with rotational-magnetic playing pieces 62A, B and C when placed in journal hole array 31 in a pivot position proximal to inside face 93 such that when rotational-magnetic ring crank 89 is rotated, one or more rotational-magnetic playing pieces 62A, B and C will also rotate and experience relative motion. In the embodiment shown ring body 89 comprises 108 rectangular magnets 96 around inside face 93.

According to the third preferred embodiment, rotational-magnetic ring crank 40 also comprises revolving handle 97 extending from top face 92 of ring body 91. Revolving handle 97, being able to freely spin and being mechanically coupled to ring body 91, enables a player to operate the rotational-magnetic ring crank 89 like a crank to provide continuous rotation. Rotational-magnetic ring crank 89 is preferably made of a low friction polymer material or alternatively comprises a low friction film affixed to contacting faces 95 and 93 or 94.

Optionally ring body 90 may further comprises a catch means (not shown) which interfaces with an undercut (not shown) of journal board 30 to prevent rotational-magnetic ring crank 89 from dislodging out of annular slot 32 during manual revolution of rotational-magnetic ring crank 89. Such catch means could be a snap-fit interface or utilize spring plungers which lock into a recess to maintain attachment of rotational-magnetic ring crank 89 to journal board 30. Although a retention means can optionally be added, this is not instrumental for practicing the inventions whereas, in most embodiments, rotational-magnetic ring crank 89 is of sufficient mass not to be easily dislodged from annular slot 32 of journal board 30.

FIGS. 10A-10E show a particular configuration pertaining to a circular journal board embodiment whereas rotational-magnetic playing piece 62A, B, and C are arranged in a symmetrical pattern in which a cross is formed within journal hole array 32. Centrally located large rotational-magnetic playing piece 62A, is magnetically coupled to all four arms of the cross formation and accordingly a larger gap is permitted between adjacent rotational-magnetic playing piece 62C than would be necessary of centrally located rotational-magnetic playing piece 62A was magnetically coupled to only a single rotational-magnetic playing piece. Optionally, the centrally located large rotational-magnetic playing piece 62A could be replaced with a rotational-magnetic disk crank 74 as shown in previous embodiments allowing rotary motion to be initiated by actuating central disk crank 74 or by actuating the ring crank 89. In this scenario, since the disk crank 74 (not shown) would be coupled to ring crank 89 via four magnetically coupled arms or rotational-magnetic playing pieces, sufficient torque would be provided to rotate ring crank 89 via hand rotation of the optionally placed disk crank 74 (not shown).

A particular advantage of the third preferred embodiment of FIGS. 9-10E is the ability to magnetically couple rotational-magnetic playing pieces 62A, B and C directly to the rotational-magnetic ring crank 89 so as to have stronger magnetic coupling through all linked paths and to generate higher torques in overcoming the inclination for magnetically coupled rotational-magnetic playing pieces 62A, B or C to lock up. Another advantage to this embodiment as that as additional rotational-magnetic playing pieces 62A, B and C are added in producing translated motion, a player can feel by touch a gradually increased force required to spin rotational-magnetic ring crank 89. This tactile aspect of play offers an added dimension to the game as the player can actually “feel” the consequences of particular rotary playing piece placement and predict the increasing likelihood of the “gear train” locking up.

Referring to FIGS. 11A-11E, various configurations of large medium and small cover plates 80A-H, 81A-H, 82A-H are shown adapted for attachment of large, medium, and small rotational-magnetic playing pieces 62A, B, and C respectively. Each of large cover plates 80A-H comprise oblong hole 83A for fitting on slender oblong handle portion 65A of large playing piece 62A. Each of medium cover plates 81A-H comprise oblong hole 83B for fitting on slender oblong handle portion 65B of medium playing piece 62B. Each of small cover plates 82A-H comprise oblong hole 83C for fitting on slender oblong handle portion 65C of small playing piece 62C.

In reference to FIG. 11A, graphical cover pieces 80A, 81A, and 82A are provided with graphical elements to indicate radial polarity and assist in visualizing magnet coupling (i.e., meshing) between rotational-magnetic playing piece 62A, B, and C. Preferably a high contrast is provided between visual indications means. For example large medium and small visual indication means 87A, 88A, and 89A respectively is designed with a dark color or pattern to represent outward north while a light color or patter is adapted to represent outward south polarity.

With regard to FIG. 11B, light and dark pie shaped sections are not intended to represent magnetic polarity but allow a user better visualize motion at higher rotational speeds than the cover pieces of FIG. 11A since higher rotational speeds would be required for larger graphical elements to appeared blurred during dynamic motion.

With regard to FIG. 11C, pie shaped graphical elements are provided in large, medium and small graphical indication means 87C, 88C, and 89C respectively whereas each pie shaped element is provided with incrementally increasing darkness or shift in color. When rotational-magnetic playing piece 62A, B, and C are configured with large, medium and small cover plates 80C, 81C, or 82C a strobe effect is visualized during dynamic rotation. Color signature of each pie shaped elements can be adapted to simulate a blinking light when undergoing rotary motion.

With regard to FIG. 11D visual indication means 87D, 88D, and 89D are provided in a toothed configuration which may or may not indicate alternating polarity of associated magnets.

With regard to FIG. 11E visual indication means 87E, 88E, and 89E are provided with a spiral for visualizing rotary motion. Perhaps spirals are one of best modes for visualizing rotary motion as they give the appearance of constant expansion when rotated in the proper direction. This is true if a counter-clockwise spiral is rotated clockwise or a clockwise spiral is moving counter-clockwise. As rotational-magnetic playing piece 62A, B and C may be moving clockwise or counter-clockwise it is preferred to provide large, medium and small graphical cover plates 80E, 81E and 82E respectively with a spiral on each side whereas the spiral is counter-clockwise on the top and clockwise on the bottom. This enables a person to configure all magnetically coupled rotational-magnetic playing piece 62A, B and C to produce the visual effect of a spiral that is constantly expanding when the rotational-magnetic disk crank 74 or rotational-magnetic ring crank 89 is rotated.

As shown in the visual indication means 87E, 88E, and 89E of FIG. 11E, graphical segments are superimposed within the spiral design to also indicate magnetic polarity of associated magnets.

With regard to FIG. 11F, circles are used as part of visual indication means 87F, 88F, and 89F.

With regard to FIGS. 11G and 11H, a pinwheel type configuration is used for visual indication means of large, medium and small graphics 87G, 88G and 89G. This produces a unique visual effect when undergoing rotary motion such that when spinning rotational-magnetic playing pieces 62A, B, and C in one direction it appears to be spinning the opposite direction. FIG. 12H shows a dual pin-wheel design whereas it can be made to appear that the inward and outward portions of corresponding rotary playing pieces are spinning in opposite directions when undergoing rotary motion.

Numerous other design and configurations of graphical indications means for rotational-magnetic playing pieces are envisioned under the scope of the present inventions. Graphical cover plates provided are removable and interchangeable as to allow a user to explore the visual effects of not only construction piece pattern arrangement but the selection of graphical cover plates to attach thereon. Thus the present invention of a rotational-magnetic construction set allows for a high degree of customization.

Referring to FIGS. 12A-12B an alternative embodiment of a rotational-magnetic disk crank 174 and small rotational-magnetic playing piece 162C is shown as if they were placed on a journal base board in a fixed spatial relationship. Although playing piece 162C looks identical to playing piece 62C of previous embodiments having the same parameter 173C and disk crank 174 looks identical to disk crank 74 of previous embodiments having the same parameter 162, the section view of FIG. 12B shows an alternative arrangement of magnetic elements according to the present invention.

Referring to FIG. 12B, a section view is shown along a line through disk bodies 164 and 164C of rotational-magnetic disk crank 174 and small rotational-magnetic playing piece 162C respectively. When placed in proximity on a journal board, rotational-magnetic disk crank 174 and small rotational-magnetic playing piece 162C are magnetically coupled so that spaced apart north and north poles provided by radial magnets 169 cause rotation of small rotational-magnetic playing piece 162C when rotational-magnetic disk crank 174 is rotated. This is facilitated primarily by the repulsion of like poles between proximally located disk bodies 164 and 164C. Correspondingly, it is not necessary according to the present invention that playing pieces comprise magnetized elements of alternating outward polarity. Alternatively magnetized elements can work primarily under repulsion whereas the magnetized elements of all rotational-magnetic playing pieces are all arranged with the same outward polarity, such as shown in FIG. 12B with all facing outwardly north, or alternatively with all facing outwardly south.

A significant advantage a construction set according to the alternative embodiment of FIG. 12B is that all rotational magnetic playing pieces would require half as many magnets as other embodiments utilizing magnets arranged in a circular pattern of alternating outward magnetic polarity, such as shown in FIG. 5C. The magnetic elements account for a substantial portion of manufacturing costs and therefore cutting the number of required magnets in half will provide dramatic cost savings for manufacturing the device.

Additionally, the alternative embodiment of FIGS. 12A-12B allows for a smaller radial pitch P162, and P174 than as can practically be achieved with twice the number of magnets having the same widths. This allows circumferential spacing between magnets can be optimized for improved magnetic coupling performance. Additionally, the block magnet used could be of an increased radial thickness that what could otherwise not be used when having to pack twice the number of magnets within the same parameter.

Like previous embodiments, the circular magnetic pitch P174 of rotational-magnetic disk crank 174 and circular pitch P162C of rotational-magnetic playing piece 162C are substantially equivalent according to the invention as needed for effective coupling between various sized playing pieces. Thus all rotational-magnetic construction pieces including disk crank 174 and large, medium and small rotational-magnetic construction pieces according to the present invention will have a substantially equivalent circular pitch for providing interchangeability whereas all rotational-magnetic construction pieces can be effectively coupled together.

The maximum working depth Dw of FIG. 12B and of FIG. 5C may or may not be equivalent based on the particular design of rotational magnetic playing pieces of the same type as disk crank 173 and playing piece 162C. Although a fewer number of magnetized elements are involved, the mass, shape and positioning of the magnetized elements 169 can be optimized to provide nearly equivalent magnetic coupling performance as pertaining to previous embodiments having twice the number of magnets 69 with alternating outward polarity.

Other embodiments within the scope of the invention include rotational-magnetic playing pieces configured for magnetic coupling whereas embedded magnets of some rotary playing piece are all arranged in an outward north polarity while playing pieces within the construction have magnets all arranged with an outwardly south polarity. Correspondingly, the principal magnetic interaction between proximally placed rotational playing pieces could be either repulsion or attraction depending on the combination. For example, if a playing piece of outwardly north magnetization was placed near a playing piece of outwardly south magnetization the magnetic coupling would be primarily facilitated by the attraction of opposite poles of interacting magnets. On the other hand, if a playing piece of outwardly north magnetization was placed near a playing piece also of outwardly north magnetization, magnetic coupling between this pair would be facilitated by the repulsion of like poles of interacting magnetic.

In addition, it is envisioned within the scope of the invention to include magnetically susceptible ferromagnetic or “soft magnetic” material between or around permanent magnets to help direct magnetic flux and to optimize magnetic coupling between rotational-magnetic playing pieces.

Although magnetic elements are shown as block magnets, alternative embodiments could utilize magnets that are cylindrical, pie-shaped or of other variable geometry.

Although the present invention has been described herein with reference to a particular embodiment, it will be understood that this description is exemplary in nature and is not considered as a limitation on the scope of the invention. The scope and spirit of the present invention is therefore only limited by the appended claims and the reasonable interpretation thereof.
