Abstract: A sports guard includes a hollow body having a pad attached to a side thereof. The pad includes a substrate and an outer layer. The substrate includes a first shock absorbing member. A second shock absorbing member is embedded into at least one section of an inner face of the first shock absorbing member. The second shock absorbing member has a shock absorbing capacity greater than that of the first shock absorbing member and is located in a position corresponding to a joint of a user wearing the sports guard. By such an arrangement, transmission of an external impact to the joint is almost impossible.

Abstract: A paint ball gun comprises a receiver including an upper compartment and a lower compartment. A bolt is slidably mounted in the upper compartment and includes a chamber in a front end thereof for receiving a bolt pin. A gas control device is mounted in the lower compartment and includes a valve assembly, a striker, and a striker spring, the bolt and the striker being connected together to move jointly. The valve assembly comprises a positioning sleeve secured in the lower compartment, a valve pin, a valve spring mounted in the positioning sleeve, a seal member mounted to a front end of the positioning sleeve, and a cap secured to an end of the valve pin. The valve pin extends through the valve spring and located in the positioning sleeve. The valve pin includes a rear end extending beyond a hole in a rear end of the positioning sleeve.

Abstract: A guard device is provided an outer surface of a sports guard. The guard device includes a substrate, a first resilient arcuate plate projecting from the substrate and having a first distal end with an inner end edge which faces the substrate, arid a second resilient arcuate plate projecting from the substrate toward the first arcuate plate and having a second distal end which contacts the inner end edge of the first distal end of the first arcuate plate. The curvature of the second arcuate plate has a vertex which has a distance to the substrate longer than a distance between the first distal end of the first arcuate plate of the substrate.

Abstract: A shock-absorbing wrist guard includes a soft piece including two ear portions, a loop pile area connected on a portion of the soft piece, an envelope connected to another portion of the soft piece and defining a plurality of slots therein, a mediate portion between the loop pile area and the envelope, an opening defined in the space portion allowing a thumb of a user to pass therethrough, and a soft strip extended from one side of the loop pile area, and a shock absorbing device received in the envelope for protecting the user's wrist.
