Abstract: An illuminating membrane switch includes an upper membrane sheet and a lower membrane sheet. The lower membrane sheet includes an electroluminescent device and a plurality of lower lead wires disposed on the illuminating surface of the electroluminescent device. An insulating spacer layer is further disposed on the illuminating surface of the electroluminescent device, and separates the upper lead wires of the upper membrane sheet from the lower lead wire. When a pressing force acting on the illuminating membrane is sufficient, the upper lead wire and the lower lead wire at the pressing position can contact each other through the opening of the insulating spacer layer so as to form a closed circuit. The keyboard can light up the symbols on the surfaces of key caps by light emitted from the illuminating membrane for a user to identify the function or alphabetic input of each key cap, and detect any input from a keystroke.

Abstract: A valve structure of a paint bullet gun including a barrel and a handle. A gunlock and a strike-controlling unit are disposed in the barrel. A valve body and an arrestor are disposed in the handle. The arrestor serves to drive the valve body. An air source serves to supply air into the valve body to control the strike-controlling unit and the gunlock to reciprocally move. The valve body has a linking section and an arresting section. A linking member and a spring are mounted in the linking section. The arresting section communicates with the linking section via a ventiduct. The arresting section is formed with a passage. An inner wall face of the passage is formed with an annular groove with slopes. The annular groove communicates with the air source via an intake. A shaft and a resilient member are accommodated in the passage. The shaft is reciprocally drivable by the arrestor and the resilient member.

Abstract: A shooting structure of a paint bullet gun, including a body section and a handle. A gunlock and a shot control unit are disposed in the body section. An air source serves to fill air into the body section. A trigger unit is disposed in the handle for controlling the shot control unit which controls the gunlock to reciprocally move. An activating chamber is formed in the body section. The gunlock is slidably disposed in the activating chamber. The activating chamber has an intake passage communicating with the air source. A space is defined between the bar body and inner wall of the activating chamber. The space is movable along with the gunlock to be aligned with the intake passage. The gunlock is formed with an internal shooting air reserving room and more than one exhaust passage communicating therewith. The shooting air reserving room has several intakes communicating with the space. A controlling valve is disposed between the exhaust passage and the shooting air reserving room.

Abstract: A shooting structure of a paint bullet gun, including a gun body and a handle. A gunlock and a shot control unit are disposed in the gun body. A trigger unit is disposed in the handle for controlling the shot control unit. An activating chamber is formed in the gun body, in which the gunlock is slidably disposed. An annular shooting air reserving room is formed on outer circumference of the activating chamber. A first intake and a second intake are formed between the shooting air reserving room and the activating chamber. A vent is formed between the air source and the activating chamber. A first space and a second space are defined between the gun body and inner wall of the activating chamber. The first and second spaces are movable along with the reciprocally moved gunlock to be aligned with the first intake or the second intake and the vent. A front section of the gunlock is formed with an internal air duct.

Abstract: A shooting structure of a paint bullet gun. The paint bullet gun includes a main body and a handle. A gunlock and a controlling unit are disposed in the main body. An air source serves to fill air into the main body. A trigger is disposed in the handle for controlling the controlling unit to control the gunlock to reciprocally move within the main body. An activating chamber is formed in the main body. The activating chamber communicates with the air source via a vent. One end of the activating chamber communicates with a barrel. A bullet-dropping port is disposed on the activating chamber near the barrel to communicate with the activating chamber. The gunlock is disposed in the activating chamber. A space is defined between outer circumference of middle section of the gunlock and inner wall of the activating chamber. The space is movable along with the reciprocally movable gunlock to be aligned with the vent. One end of the gunlock is connected with the controlling unit.

Abstract: A paint ball gun has a first chamber, a second chamber, a percussion member in the first chamber, an aperture communicating the chambers, a valve in the second chamber, a rear plunger at an end of the second chamber, a firing member in the second chamber and connected to the percussion member, a handle with a trigger assembly therein, and a percussion device having a base with a chamber therein, an inlet and an outlet communicating the second chamber and the rear plunger with the chamber respectively. A guiding block and a rotator are received in the chamber. The guiding block has a first and a second tunnel communicated with the inlet and the outlet respectively. The rotator has a storage chamber therein and two bores. The rotator is rotated to selectively align the bores of the rotator to the first and second tunnels of the guiding block respectively.

Abstract: A paint ball gun has a gun body and a trigger assembly therein. The gun body has a first chamber, a second chamber and a tunnel between the first and the second chambers. A rod, a percussion member and a shaft are provided in the first chamber, the second chamber and the tunnel respectively. A rear block connects the rod and the percussion member. A valve is provided in the first chamber and activated by the rod. A controller is provided in the gun body, has a guiding channel to be manipulative for communication the first chamber and the tunnel and an exhausting channel to be manipulative for communication with the tunnel. The trigger assembly is manipulative to issue the gas in the first chamber to the second chamber for movement the shaft and to exhaust the gas in the tunnel after moving the shaft out.

Abstract: A percussion device of a paintball gun includes a piston and an action reciprocally movably received in a body of the paintball gun. A snapper is movably mounted in between the piston and the action for selectively connecting the piston and the action. An actuated rod is movably received in the action and has a stick longitudinally extending form the actuated rod. A neck is formed on the stick for defining a receiving space. The piston and the action are connected to each other when the snapper abuts the stick, and the action is in a free condition and can be detached from the paintball gun when the snapper is received in the receiving space.
