Nestable starting block

Abstract

The present invention is a starter block for use in athletic events. The bottom-surface cleats which anchor the starting block to the ground are associated with blind bores extending through the lower surface. Each cleat has an associated blind bore. The positioning of the blind bores relative to the cleats allow the cleats of one starting block to be received by the blind bores of another starting block, and vice versa. This configuration allows the blocks to be stored easily and safely.

DETAILED DESCRIPTION

(7) FIG. 1 shows the visible surfaces of the block 10 when placed on the running surface. The block 10 comprises a wedge-shaped body, and includes an inclined surface 11 at the top onto which a runner places one of his or her feet. A second block, not shown, is used for the other foot. The body of the block 10 may be made from any suitable rigid material, such as plastic, wood, metal, or composite materials, or any combination thereof. As shown in FIG. 1, the inclined surface 11 preferably comprises a stippled, mottled, knurled, grooved, or otherwise roughened surface to give a high-friction, minimal-slip interface between the inclined surface 11 of the block 10 and the runner's shoe. To reduce weight, material, and cost, at least one block hollow 17 may extend into at least part of a lower surface 13 of the block 10. To strengthen the block 10, at least reinforcing rib 18 may extend across the block hollow 17.

(8) FIG. 2 shows the underside of the block 10. The block 10 includes at least one, and preferably two, three, four, or more cleats 12 extending from the lower surface 13 of the block 10. The cleats 12 may be integrally formed with the block 10 or may be removable, using the threaded, friction-fit, or snap-in type cleat connections conventionally used in cleated shoes (such as the removable cleats found on racing flats, golf shoes, and the like). Removable cleats 12 allow substitution of longer or shorter cleats 12 or cleats 12 having a different anchoring configuration to be installed based on the type and/or conditions of the running surface. By way of non-limiting example, when used on natural surfaces such as turf or clay, longer cleats 12 will anchor the block 10 to the surface more firmly. On closely groomed surfaces or artificial surfaces, shorter cleats 12 might suffice, and would have less potential to mar the running surface.

(9) Each cleat 12 is paired with a corresponding blind bore 14 extending through the lower surface 13. The exemplary embodiment of the block 10 shown in FIG. 2 includes four sets of cleats 12 and corresponding blind bores 14. As described more fully below with respect to FIGS. 3, 4, and 5, the cleats 12 and blind bores 14 are dimensioned, configured, and positioned in such a way that two blocks 10 and 10′, rotated at a 180° offset to one another, can be nested together via contacting their lower surfaces 13 and 13′ together. In other words, when the block 10 is rotated 180° about the horizontal axis A-A′ (as seen extending across and through the center point of the lower surface 13 in FIG. 2) from a first position to a second position, the cleats 12 in the first position are in the same location as the blind bores 14 in the second position. The reverse is also true, that is, in the first position the blind bores 14 are in the same location as the cleats 12 in the second position.

(10) Typically, at least one reversible fastener 16 is located in the center of the lower surface 13 of the block 10. As shown in FIG. 2, the exemplary fastener 16 is a magnetic washer or button held in place by a separate anchor, in this embodiment a threaded screw 15. In other embodiments, the fastener 16 does not require a separate anchor, being held in place via threaded, friction-fit, adhesive, or snap-in connections with the block 10. The fastener 16 may be any reversible fastener now known or developed in the future, such as a male/female friction fastener, a hook-and-loop fastener, a slot-and-tab fastener, any other mechanically interlocking fastener, and the like. The fastener 16 is dimensioned and configured to reversibly connect two blocks 10 together in face-to-face orientation via their lower surfaces 13 and hold them in such a configuration.

(11) The nested and fastened configurations are depicted in FIGS. 3, 4 and 5, which shall be described together. As shown in FIG. 3, two blocks according to the present disclosure, a first block 10 and a second block 10′, are rotated 180° relative to each other and stacked in face-to-face orientation via their respective lower surfaces 13 such that their upper, inclined surfaces 11 are parallel to each other. As shown in the partial cutaway view of FIG. 4, the cleats 12 and blind bores 14 are configured in such a fashion that cleats 12 of the first block 10 extend into the blind bores 14′ of the second block 10′. Likewise, the cleats 12′ of the second block 10′ extend into the blind bores 14 of the first block 10. In this fashion, the two blocks, 10 and 10′ can be nested together in a very compact configuration, without any of the cleats 12 being exposed, preventing damage to the cleats 12 and preventing the cleats 12 from causing damage. The exemplary two blocks 10 and 10′ are then reversibly held together in the nested configuration via fasteners 16 and 16′ as shown in the center, partial cutaway view depicted in FIG. 5.
