20110056469ROULETTE WHEEL-TYPE FUNNEL DEVICE FOR USE WITH HOPPER OF PAINTBALL MARKER - A roulette wheel-type funnel device for use with a hopper of a paintball marker is configured according to the hopper and essentially includes a funnel body and a roulette wheel. The funnel body is formed therein with a receiving chamber connected with a ball channel. The ball channel is in tangential communication with the receiving chamber so as to form a smooth guide path. A covering plate formed adjacent to an inlet of the ball channel and has an inclined surface and extends into the receiving chamber. The roulette wheel has a sloped surface formed with at least one fin. The roulette wheel is driven to rotate by a motor and facilitates rolling of paintballs. With the ball channel being in tangential communication with the receiving chamber and forming the smooth guide path, the paintballs are fed easily and smoothly into the ball channel and prevented from being stuck.03-10-2011
20110073092HOPPER STRUCTURE OF PAINTBALL MARKER - A hopper structure of a paintball marker includes a hopper body, a paintball holder, an upper cover, and first and second connecting elements. The hopper body has opposite first and second pivot portions. The first pivot portion has opposite and mutually communicating first pivot holes. The second pivot portion has opposite and mutually communicating second pivot holes. After a third pivot portion of the paintball holder is received in the first pivot portion, a fourth pivot portion of the upper cover is received in the second pivot portion. Thus, the paintball holder and the upper cover are stacked vertically on the hopper body. The upper cover, the paintball holder, and the hopper body are pivotally connected by the first and second connecting elements such that the assembled hopper structure is conveniently opened and closed and will not fall apart when accidentally dropped to the ground or hit during use.03-31-2011

20090064980Paintball gun with a window design to monitor the interior of the paintball gun - A paintball gun with a window design to monitor the interior of the paintball gun includes a barrel, a sleeve, a thimble and a rear lid. The sleeve and the thimble are disposed in the barrel. The rear lid is located at a rear end of the barrel. The barrel is provided with at least one window at an outer side thereof. The sleeve is hollow and transparent. When some parts in the barrel are malfunctioned, the windows and the transparent sleeve will facilitate the maintenance person to locate the problems.03-12-2009
20090133679Electronic device to control shooting of a BB gun - An electronic device to control shooting of a BB gun includes a barrel, a trigger, a switch, a control unit, a solenoid valve and a sensor. The barrel is hollow and interconnected with a loading hole. The sensor is located in the loading hole. The trigger corresponds to the switch. The switch is electrically connected to the control unit. The control unit is electrically connected to the solenoid valve. The solenoid valve is to control pressurized gas entering said barrel. When the trigger triggers the switch and the sensor detects a BB ball dropping through the loading hole into the barrel, the sensor will transmit a signal to the control unit and the control unit will activate the solenoid valve to control pressurized gas entering said barrel.05-28-2009
20090133681Multi-purposes mechanism for shooting apparatus - A multi-purposes mechanism for shooting apparatus includes a gun body, a barrel, a shooting member, and a rear cap. The gun body comprises a hollow tube perpendicularly interconnecting with a first loading hole at a center portion of the hollow tube. A first stage is formed on an inner wall of the tube in front of the first loading hole. A second stage is formed on the inner wall of the tube in back of the first loading hole. The barrel is disposed in the tube before the first loading hole, and has a first engaging ring corresponding to the first stage of the tube. The shooting member is disposed in the tube after the first loading hole, and has a second engaging ring on an outer wall thereof corresponding to the second stage of the tube. The rear cap is connected to a rear end of the tube.05-28-2009
20090223501PAINTBALL GUN WITH A PRESSURE GAUGE DEVICE - A paintball gun with a pressure gauge device includes a rear cap, a pressure gauge, and a canopy. The rear cap has a first end and a second end. The rear cap has a compartment at the first end adapted to accommodate the pressure gauge. The second end of the rear cap has a piston block. The piston block has an air passage interconnecting with an air passage of the pressure gauge. The canopy is fixed to the rear cap which is then secured to a rear end of a barrel in the paintball gun. A triggering block is provided in the barrel. The triggering block engages with the rear cap. This design can obtain the air pressure within the paintball gun so that the user may apply air pressure to the paintball gun when necessary.09-10-2009
20090266348Adjustable Paint Ball Gun Triggers - A paint ball gun trigger for easy of replacement and orientation change is disclosed, which includes a lower trigger body, an upper trigger body, and an orientation-setting unit. The lower trigger body includes at the top a lower-and-upper body connecting piece, which further includes a screw hole and a positioning hole communicating with said screw hole. The upper trigger body includes at the bottom a lower-and-upper body connecting chamber, and at the lateral side a stabilizing hole communicating with said lower-and-upper body connecting chamber. The orientation-setting unit includes a setting piece, a blocking piece, an elastic element, and an adjusting screw, each of which is assembled in order by screwing into said screw hole of said lower trigger body for orientation change of said lower trigger body.10-29-2009
20100000505BB gun loading device - A BB gun loading device includes a feeder, a loading unit, a power breaker, and an ejection unit. The loading unit includes a worm, a driven pulley, and a motor. The worm is inserted into the feeder and coupled to the driven pulley which is driven by the motor to rotate. The rotation of the driven pulley links the worm to load BB balls in the feeder for shooting. The power breaker is adapted to cut off power supply. The ejection unit includes a press rod and a touch switch. By pressing the press rod, the touch switch is activated to link the worm to move backward so as to clear the jammed chamber.01-07-2010
