20120055720 | AUXILIARY POWER DEVICE OF BICYCLE - An auxiliary power device of a bicycle includes a driving member and a base member provided at a first section and a second section of the bicycle respectively. The first section and the second section are two parts of the bicycle, which has a relative motion therebetween in cycling. An input member is provided to the base member to be driven by the driving member when the first section moves relative to the second section. The input member turns a power storage member to store a power. A control member is provided for manipulation to release the power stored in the power storage member for moving the bicycle forward. | 03-08-2012 |
20110214531 | TRANSMISSION APPARATUS WITH MULTIPLE CHANNELS - A transmission apparatus of the present invention can transmit power via different inputs, and release power via specific outputs. The transmission apparatus of the present invention is connected to a first input and a second input, both of which produce a forward rotation and a rearward rotation, and a first output. The present invention includes a first transmission device connected to the first input and the first output and is driven to turn by the first input, wherein the first transmission device further has a one way transmission member to transmit the forward rotation of the first input to the first output, and a second transmission device connected to the second input and the first output and is driven to turn by the second input, wherein the second transmission device has a one way transmission member to transmit the forward rotation of the second input to the first output. | 09-08-2011 |
20110186372 | BICYCLE WITH AUXILIARY POWER SYSTEM - A bicycle is equipped with an auxiliary power system to provide extra power for driving the bicycle moving forward. The auxiliary power system includes a base fixed to a frame of the bicycle, a power storage device connected to the base, and a ratchet device connecting the power storage device and a main transmission system of the bicycle. When paddles of the bicycle are turned in a forward direction, it may drive the bicycle moving forward but not the power storage device through the ratchet device. When the paddles are turned in a rearward direction, it may drive the power storage device through the ratchet device to store extra power in the power storage device. Rider may release the power stored in the power storage device to drive the bicycle moving forward through the ratchet device and the main transmission system. | 08-04-2011 |
20100223953 | DEVICE FOR HOLDING FRAGRANCE - A device for holding fragrance having a container with a porous sidewall and an absorber received in the container. The absorber absorbs perfume to produce fragrance. The device of the present invention may be a ring, earring, necklace, brooch, hair adornment, pin, bracelet etc. Moreover, the device of the present invention may be a perfume spray used in the car or bathroom also. | 09-09-2010 |
20100219006 | AUXILIARY POWER DEVICE OF BICYCLE - An auxiliary power device of a bicycle includes a driving member and a base member provided at a first section and a second section of the bicycle respectively. The first section and the second section are two parts of the bicycle, which has a relative motion therebetween in cycling. An input member is provided to the base member to be driven by the driving member when the first section moves relative to the second section. The input member turns a power storage member to store a power. A control member is provided for manipulation to release the power stored in the power storage member for moving the bicycle forward. | 09-02-2010 |
20100212649 | PAINTBALL FEEDING DEVICE OF PAINTBALL GUN - A paintball feeding device of a paintball gun includes a container, in which paintballs are received, mounted on the paintball gun. A transporting member is received in the container. The transporting member has ball carrying portions to hold the paintballs. The paintball gun has a frame with a chamber therein, and the frame is provided with an inlet and an outlet on opposite sides thereof to be communicated with the chamber respectively. A driving member is connected to the transporting member for driving the transporting member to have the ball carrying portions entering the chamber via the inlet in sequence and leaving the chamber via the outlet. | 08-26-2010 |
20100206283 | SINGLE-CHAMBER TYPE FIRING MECHANISM OF PAINTBALL GUN - A firing assembly of a paintball gun includes a piston, a spring, and a valve installed in a chamber in a frame of the paintball gun. The piston is a bar-like member having front member, a connection member, and a rear member. The connection member is smaller than the front member and the rear member to form a space thereunder. The valve is in the space to divide the space into a front room and a rear room. The spring urges the piston forward to have the rear member pressing an actuator of the valve that a high pressure gas will escape out of the valve to spurt out of the apertures via the rear room, the channels, and the front room. The high pressure also pressurizes the rear member to move the piston backward and compress the spring. | 08-19-2010 |
