A collapsible net for a game play is disclosed. The collapsible net includes a plurality of net-modules, each of the plurality of net-modules including a first-type coupler adjoining a left-side edge and a second-type coupler adjoining a right-side edge of each of the plurality of net-modules. The first-type coupler is configured to engage with the second-type coupler to couple the net-modules with one another, to thereby define an expanded length of the collapsible net.

An inflatable apparatus for striking and propelling an object when affixed to a limb of a body preferably includes first and second oppositely facing walls, the first wall defining a striking surface for striking and propelling the object therefrom; and one or more sidewalls extending between and connecting the first and second oppositely facing walls, wherein the one or more sidewalls define an opening configured to permit passage of the limb from an exterior of the apparatus into an interstitial space of the apparatus for affixing the apparatus on the limb. The inflatable apparatus further includes one or more fluid-impermeable, expandable chambers in fluid communication with one or more ports whereby fluid introduced through the one or more ports enters into the one or more chambers for expanding the one or more chambers and tensioning the first wall defining the striking surface. A paddle-type game preferably uses such inflatable apparatus.

A paddle is for corporal discipline. The paddle includes a handle, and a paddle portion having a base, and an elongate flat member extending from the base. The elongate flat member is to be used for striking a subject to be disciplined in the corporal discipline. The paddle also includes a hinge device comprising a first arm coupled to the handle, a second arm coupled to the base, a pivoting hinge coupled between the first arm and the second arm and configured to switch the paddle portion between a locked state where the paddle portion and the handle are substantially parallel and a folded state where the paddle portion and the handle freely move, and a settable feature. The settable feature selectively changes a threshold pivoting force of the pivoting hinge for causing the paddle portion to switch from the locked state to the folded state.

A composite panel structure has opposing outer walls or surfaces and a core comprising a plurality of ribs extending between and connected to the outer walls and defining chambers which are filled with expanding foams, non-expanding foams, gases, or a combination thereof. The outer panel surfaces and internal chamber walls or ribs are made of woven or non-woven fibrous material impregnated with one or more resins. The panel structure may be used for making a variety of products including sports equipment such as sports paddles, surfboards, kite boards, skateboards, wakeboards, as well as construction panels for walls, ceilings or floors, display panels, panels for the vehicle industry, furniture, and other structures requiring high strength to weight properties.
