DETAILED DESCRIPTION

(8) With collective reference to FIGS. 1 and 2, a magnetic toy construction block 10 includes a housing 12 and a pair of end caps 14, 16. The housing 12 and the end caps 14, 16 are made from a non-magnetic material, such as a suitable plastic, which can be opaque, as shown, or, in the alternative, transparent (see FIGS. 3-6) or translucent.

(9) Turning first to the housing 12, but with continued reference to FIGS. 1 and 2, the housing 12 is formed by three identical and substantially planar side panels 18, 20, 22, each of which has a rectangular shape. The side panel 18 has an interior face 24 provided with an arcuate groove or trough 26 for a purpose to be described hereinafter. Like the side panel 18, the side panel 20 has an interior face 28 provided with an arcuate groove or trough 30 for a purpose to be described hereinafter. Like the side panels 18, 20, the side panel 22 has an interior face 32 provided with an arcuate groove or trough 34 for a purpose to be described hereinafter.

(10) Referring still to FIGS. 1 and 2, the side panels 18, 20, 22 are permanently joined together (e.g., by any suitable mechanism, such as ultrasonic welding, gluing, etc.) to form the housing 12, which is essentially an open-ended prism having a triangular cross-sectional shape. More particularly, the housing 12 has an interior 36 delimited by the side panels 18, 20, 22, one of which (i.e., the side panel 22) is broken out in FIG. 1 to facilitate consideration and discussion. The junctures of the side panels 18, 20, 22 provide the housing 12 with three longitudinal edges 38. The interior of each edge 38 includes an integrally formed, open-ended and elongated half-pipe 40 adapted to perform a socket-like function in that its open end receives a corresponding one of three mounting posts 42 (only two of which are visible in FIGS. 1 and 2, but all three being visible in FIG. 3), each of which extends inwardly (i.e., towards the end cap 16) from a respective corner 44 of the end cap 14. Before turning to a further discussion of the end caps 14, 16, it is noted that the troughs 30 and half-pipes 40 extend in a direction which is parallel to an imaginary central longitudinal axis A passing through the interior 36 of the housing 12.

(11) Turning now to the end caps 14, 16, but with continuing reference to FIGS. 1 and 2, the end cap 14 has a tubular pedestal 46 that extends along the central longitudinal axis A and that functions as part of a support structure for a neodymium ring magnet 48. In a similar fashion, the end cap 16 has a tubular pedestal 50 that extends along the central longitudinal axis A and that cooperates with the pedestal 46 to form the support structure for the ring magnet 48, whose structure and function will be described in greater detail hereinafter.

(12) Returning to the prior discussion of the end cap 14, each of its three mounting posts 42 is sized and shaped to be received within a corresponding one of the half-pipes 40 that extend along the longitudinal edges 38 of the housing 12. While the end cap 16 is shown as an integrated part of the housing 12, it should be understood that the end cap 16 could be formed separately from the housing 12, in which alternative form the end cap 16 could have mounting posts (not shown) similar in structure and function to the mounting posts 42 of the end cap 14.

(13) With particular reference to FIG. 1, the tubular pedestal 50 of the end cap 16 has a circular rim 52 adapted to perform a function that will be described hereinafter. A concentric post 54 extends from the end cap 16 through the tubular pedestal 50. As can be seen in FIG. 1, the post 54 has an outer diameter that is less than the inner diameter of the pedestal 50 and a length that is greater than the length of the pedestal 50. The end of the post 54 extending beyond the rim 52 of the pedestal 50 is provided with a recess 56 for a purpose to be described hereinafter.

(14) With particular reference now to FIG. 2, the tubular pedestal 46 of the end cap 14 has a circular rim 58 adapted to perform a function that will be described hereinafter. A concentric post 60 extends from the end cap 14 through the tubular pedestal 46. As can be seen in FIG. 2, the post 60 has an outer diameter that is less than the inner diameter of the pedestal 46 and a length that is not greater than the length of the pedestal 46. The post 60 is countersunk to form a blind bore 62, which is sized and shaped to receive the end of the post 54 containing the recess 56. The blind end of the bore 62 has a centering lug 64 adapted to be received within the recess 56 at the end of the post 54. Each edge of the end cap 14 is provided with an arcuate protuberance 66 having a shape that complements the shape of a corresponding one of the troughs 30 in the side panels 18, 20, 22 of the housing 12.

(15) Prior to attaching the end cap 14 to the housing 12 in the manner described above, the ring magnet 48, which has a central aperture 68 extending therethrough, is slid over the post 54 until it comes into contact with the rim 52 of the pedestal 50. The end of the post 54 containing the recess 56 extends through and beyond the ring magnet 48, which is rotatably supported within the housing 12 by the pedestal 50 and the troughs 30 in the side panels 18, 20, 22.

(16) The next step in the assembly process involves the application of the end cap 14 to the housing 12 in the manner described hereinabove (i.e., with the mounting posts 42 of the end cap 14 received in the socket-like ends of the half-pipes 40 of the housing 12). Once applied to the housing 12 in this manner, the end cap 14 would be permanently bonded to the housing 12 by any suitable mechanism, such as ultrasonic welding, gluing, etc., thereby sandwiching the ring magnet 48 between the pedestal 46 and the pedestal 50 in a longitudinally fixed but circumferentially rotatable manner. The result of such a construction is that the ring magnet 48 cannot be inadvertently or accidentally removed from the magnetic toy construction block 10 by a user or another person. In other words, the ring magnet 48 is effectively entombed within the magnetic toy construction block 10 for safety purposes and otherwise.

(17) The ring magnet 48 is radially magnetized, whereby its poles lie in close proximity to one or more of the side panels 18, 20, 22 of the housing 12. Because the ring magnet 48 is rotatably supported within the housing 12, the positions of its poles relative to the side panels 18, 20, 22 are variable. Thus, when the magnetic toy construction block 10 is placed adjacent other similar magnetic toy construction blocks 10 (see FIGS. 4 and 5) and/or dissimilar magnetic toy construction blocks 10′ (see FIG. 6), opposite poles of the magnets contained in the adjacent blocks will automatically align to magnetically attach the blocks together. When several such blocks are attached in this manner, a user can arrange the blocks into various different and interesting shapes and structures, examples of which are shown in FIGS. 4-6.

(18) It will be understood that the embodiments described hereinabove are merely exemplary and that a person skilled in the art may make many variations and modifications without departing from the spirit and scope of the present invention. For instance, the ring-type magnet and other novel features of the above-described magnetic toy construction block 10 may lead to applications and/or uses outside the toy field.
