Correction 1984. 8.16 The claims for utility model registration and the brief description of the drawings are amended as follows. O Scope of Claim for Utility Model Registration The main axle center of an ordinary bicycle is provided with pedal pressure points with gears and cranks fixed in the middle of the front and rear wheel axles at three locations, and the length of the cranks is limited to approximately 18 cm. Power is transmitted through an 18 cm stack rod, but the force applied to the betaru is blocked by a gear with a radius of 9 cm, and the diameter of the rear fill gear connected by a chain is reduced to double the rotation. At the same time, the transmission of force has been reduced, and the transmission within this framework has a considerable effect by effectively using the applied force, and especially on flat ground, inertia is generated. It's advantageous. However, increasing the number of rotations puts a heavier burden on the legs, and in order to save labor, it is necessary to increase the number of rotations at which the force is applied. As described above, within the reduced framework, inversely proportional existence is present and the efficiency of the applied force decreases. The above is the current state of bicycles, and this proposal aims to expand the scope of the force given above and make the transmission more effective. The main shaft centers of the first offender are shown in Figure 1 A, H, and W, and there are four locations including the front wheel shaft center, which is omitted in the drawing, and the layout is as shown in Figures 1 and 2. The labor-saving gears arranged in parallel in front and back on the right side are connected by a chain, and the deformed crank on the left side is arranged. The force is generated at the center of the axis of the mouth, and this is transmitted to the mouth by the mouth to promote labor saving. The labor-saving gear shown in Figures 1 and 2 has its axis located near the periphery of the circle, leaving only the necessary number of tooth profiles around the same position, and cutting out the rest and storing them in the attached metal plate. The shape shown in Figure 2 is used to prevent the chain from coming off during rotation. The linked torsion has a complete tooth profile, and rotates simultaneously with the nut to draw a swinging trajectory without causing any slack in the chain, increasing the number of chain arches. As soon as it enters the operating range of the left front long lever crank, the right labor-saving gear rotates backwards, exposing its non-labor-saving surface to the front, and at the same time, the gear shifts its decimal tooth profile in the space between the upper and lower chains at the rear, causing the chain to shift. The chain becomes unable to be tractioned and starts to spin, and the small number of teeth on the upper part of the chain becomes a lever, and the pedal becomes as shown in Fig. 1, and when it reaches the position where it starts to be depressed, the first half of the pedal becomes effective.
This operation occurs in the long position, but the connection touches the inside of the pedal at the front and rotates freely, synchronizing with the rotation of the crankshaft. The rear tail part is dovetailed as shown in Figure 3 A and B, and the female dove A small groove part is inserted into the male dove part B from the front on the left side of the tail part to make it slidable, and the part is slidable to the outside of the long lever crank. In addition, a mechanism similar to a radit wrench is built into the part that hits the hinge, making it possible to correct the difference in the rotation direction applied to both ends of the long lever crank when it is raised toward the shaft center. In this way, the labor-saving rate of the labor-saving gear is at most about one times that of a practical vehicle.
The main aim is to increase labor savings by about twice as much as the upper and lower parts of the long lever crank, and to strengthen the source of pedal force by working in harmony with both. Bicycle labor-saving aids for which registration is requested, including all devices equipped with the above-mentioned different labor-saving mechanisms on the left and right sides. Brief explanation of the drawings Figure 1 is a 174 side view, with the front and rear wheels, transmission, steering wheel, saddle, and other attached parts omitted.

Claims (1)

[Scope of Claim for Utility Model Registration] The main axle center of an ordinary bicycle is provided with pedal pressure points with gears and cranks fixed between the front and rear wheel axles at three locations, and the length of the cranks is limited to approximately 18 cm. Power transmission is 18cm
The force applied to the pedal has a radius of 9c.
The diameter of the rear fill gear, which is blocked by the M gear and further connected by a chain, was made smaller in diameter to double the rotation, and the transmission of power was also reduced, and the transmission in this frame gave When the force is used effectively, it has a considerable effect, and it is especially advantageous on flat ground because it generates inertia. However, increasing the number of rotations increases the burden placed on the legs, and in order to save labor, the number of rotations of the applied force must be increased. As described above, within the reduced framework, inversely proportional existence is present and the efficiency of the applied force decreases. The above is the current state of bicycles, and this proposal aims to expand the scope of the force given above and make the transmission more effective. The main axle centers of the first offender are shown in Figure 1 A, H, and W, and there are four locations including the front wheel axle center, which is omitted in the drawing, and the layout is as shown in Figure 1.2. Ho on the right side. The labor-saving gears that are parallel to each other in front and rear are linked by a chain, and the deformation/crank is placed on the left side, and only the labor-saving aspects of both are utilized during the first half of effective rotation, helping to promote labor-saving operation sources.
It was created at the center of the axis of the wa and transmitted to the river by the t to promote labor saving. , The labor-saving gear shown in Fig. 1.2 has its axis located near the periphery of the circle, and only the necessary number of teeth are left around the same position, and the rest are cut out and stored in the attached metal plate. , as shown in Figure 2, to help prevent the chain from coming off during rotation. The linked torsion has a complete tooth profile, and rotates simultaneously with the nut to draw a swinging trajectory without causing any slack in the chain, increasing the number of chain arches. As soon as it enters the operating range of the left half long lever crank, the right labor-saving gear rotates backwards to reveal the non-saving surface in front, and at the same time, the gear shifts its decimal tooth profile in the space between the upper and lower chains at the rear, and the index of the chain. The pedal becomes disabled, spins idly, and only a limited number of teeth are applied to the upper part of the chain, and the pedal becomes as shown in Fig. However, the connection touches the inside of the pedal at the front and rotates freely, synchronizing with the rotation of the crankshaft. The rear tail part is dovetailed as shown in Figure 3 A and B, and the female dove A small groove part is inserted into the male dove part B from the front on the left side of the tail part to make it slidable, and the part is slidable to the outside of the long lever crank. In addition, the same mechanism as a radit wrench is built into the part that hits the hinge, and it is possible to correct the difference in the direction of rotation applied to both ends of the long lever crank when it is raised toward the axis. The labor saving rate of the labor saving gear is up to approximately one times that of a practical vehicle,
The main aim is to increase labor savings by about twice as much as the upper and lower parts of the long lever crank, and to strengthen the source of pedal force by working in harmony with both. Bicycle labor-saving aids for which registration is requested, including all devices equipped with the above-mentioned different labor-saving mechanisms on the left and right sides.
