摘要:
A customizable hockey skate includes a removable runner-blade assembly such that a runner-blade assembly having a first stiffness may be readily replaced with a runner-blade assembly having a second stiffness. The runner-blade assembly may be removably attached to first and second cups that are optionally removably attached to the sole of a skate boot. The first and second cups optionally are removably attachable at multiple lateral locations on the sole. Mounting plates to which the first and second cups are mounted may be included to provide damping interfaces between the first and second cups and the boot sole. The first and second cups may be separately removable from the sole such that the first cup may be replaced with a third cup (for example, a cup having a different stiffness than the first cup) without removal of the second cup.

A safety game ball (21) with a cloth cover (23) having a flat stitched seam (31) and method of manufacturing the same. The safety game ball (21) includes a spherical core (22) formed of an elastically-deformable material, a flexible cloth cover (23) mounted over and enclosing the core (22) and having cover edges (28, 29) juxtaposed along a circumferentially-extending butt seam (31). An edge binding assembly (32) including a cloth-edge reinforcing strip (33) and a plurality of binding stitches (34) closely proximate to each of the edges (28, 29) is provided, and a plurality of seam stitches (36, 36a) extend from a position (37) inwardly of the edge binding assembly (32) on one side of the seam (31) to a position (38) inwardly of the edge binding assembly (32) on the other side of the seam (31).

Composite structures are disclosed that include co-molded logosystems. A representative composite hockey stick having a tubular hollow shaft, a blade, and a weight-adjustable end-plug is disclosed. The blade includes one or more logo systems co-molded to an external surface of the blade. Methods and suitable materials for constructions of the various components and composite constructs are also disclosed.

A composite hockey stick having a tubular hollow shaft and a blade is disclosed. The shaft includes a region of focused weight in the form of an overlay coating that is applied on top if the internal surfaces of the cured shaft using a coating plug. The blade includes a focused weight region that is inserted into a cavity within the cured composite blade. Methods and suitable materials for constructions of the various components of the blade and shaft are also disclosed.

A bicycle wheel includes a central hub and a rim including multiple openings positioned about the circumference of a radially inner surface of the rim. A rivet nut or similar attachment element is positioned in each opening and coupled to the rim. A first end of a nipple or similar coupling element is threaded into or otherwise attached to each rivet nut. A first end of a spoke is threaded into or otherwise attached to a second end of each nipple. A second end of the spoke is coupled to or engaged with the central hub. Each nipple optionally includes left-hand external threads and right-hand internal threads, or right-hand external threads and left-hand internal threads, such that rotation of the nipple simultaneously tightens or loosens the nipple with respect to both the rivet nut and the spoke.

A protective sports helmet includes features that promote efficient fit adjustment and efficient donning and removal of the helmet. The helmet optionally includes a front shell portion pivotably connected to a rear shell portion to promote easy donning and removal of the helmet. Further, the upper region of the front shell optionally is longitudinally adjustable relative to the upper region of the rear shell. Cam mechanisms optionally are provided on the helmet shell for securing straps of a chin cup at desired lengths. The cam mechanisms optionally each include a self-energizing grip member that increasingly engages the strap when the strap is pulled taut while the cam mechanism is in the locked position. A face guard optionally is attached within the helmet shell structure, or within padding inside the shell, which provides a smooth helmet exterior and promotes distributed energy transfer from the face guard to the helmet shell.

A skate assembly includes a shell structure and a removable tendon guard. The shell structure includes a heel portion, a lateral ankle portion, and a medial ankle portion. The heel portion is formed to cover a human heel. The lateral ankle portion is formed to extend beyond the heel portion. The medial ankle portion is formed to extend beyond the heel portion. The lateral ankle portion and the medial ankle portion are spaced apart to form a notch extending toward the heel portion. The removable tendon guard is removably attached between the lateral ankle portion and medial ankle portion to cover the notch.

A hockey skate (5) includes a composite boot form (10) having a rigid lower portion (12) and a less rigid upper portion (14), a skate quarter (22) attached to the upper portion (14) of the boot form (10) to overlie an upper region of a wearer's foot, and a tendon guard (20) attached to the upper portion (14) of the boot form (10) and positioned at a rear region of the boot form (10). The upper portion (14) may be made of a thermoformable material that conforms to the shape of a wearer's foot and ankle. The construction of the boot form (10) - particularly the lower portion (12) of the boot form (10) - may be varied across different size ranges by, for example, varying the fiber angles in the composite material. Varying the stiffness of the lower portion (12) of the boot form (10) in this manner allows the flexibility of different sized boots (5) to be substantially equalized. The skate quarter (22) and other skate-boot features may readily be attached to the upper portion (14) of the boot form (10) via stitching, rivets, or other connectors. The boot form (10) also may include an integral toe cap (26) having a flange (25) or other element to which the skate tongue (30) and other elements may be connected.

A ball bat includes a barrel having one or more integral features for selectively stiffening regions of the barrel. The barrel may include an indented region forming a rib projecting inwardly into the barrel. Alternatively, one or more inwardly projecting lips may be formed on adjoining barrel sections that are bonded, welded, or otherwise attached to each other, such that an integral, internal rib is formed in the barrel. The internal rib stiffens the barrel, thus reducing the barrel's BBCOR. One or more integral ribs may be provided at any desired barrel locations for selectively limiting the barrel's performance without appreciably increasing the moment of inertia of the ball bat. In another embodiment, a joint, to which two barrel sections are bonded, welded, or otherwise attached, includes an inwardly projecting member that stiffens the barrel, thus reducing the barrel's BBCOR.
