Abstract

This invention relates to a novel bicycle transmission mechanism by which the rider, replacing present circular pedaling with vertical reciprocating motion, uses gravity potential energy of human body to alternatively press down a seat and pedals alternatively to transmit the power to the front chainwheel through a pair of linear sliding rod members with the working directions opposite to each other, to make two independent and parallel BB axle gears driving the rear flywheel alternatively by roller chains wound around in a special manner, so as to rotate the rear chainwheel and make the rear wheel of the bicycle to generate power. This invention completely utilizes 70% of gravity potential of the human originally vanished on the saddle, and make the energy to transmit with linear sliding member without the occurrence of 1-(2/π) energy loss due to angle effect when driven by cranks, capable of increase 3-4.5 times of power ultimately, so as to realize the following objectives of: 1. using greater gear ratio to increase the speed and increase the practical distance of bicycle; 2.being a power saving, high speed, and convenient manpower transportation tool, capable of becoming the first choice of normal means of transportation for short and medium distance and increasing the exercising opportunity; 3. using both feet to pedal at the same time with the leg within a better joint angle range, capable of enhancing the riding stability and reducing exercise injury.

Description

201107186 VI. Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to the technical field of bicycles, and provides a new bicycle transmission device, in particular, a sliding rod rotating gear with a tooth attached, through a chain Pass gravity to the rear wheel to make it rotate. [Prior Art] [0002] A general bicycle (a bicycle without a motor assist unit) includes an artificial power drive system for transmitting a force applied to the pedal by artificial power, for example, an operator interacts with the pedal to drive the crank, and the rotation is fixed. The drive sprocket on the pedal Han forward forwards forward, and the driven sprocket of the rear wheel is driven by the key bar mounted on the drive sprocket to drive the P condensing ^^:. [0003] Nowadays, due to the shortage of energy, the price of oil is high. Bicycles are a kind of light, pollution-free and fitness-oriented vehicles, so they are widely loved by the public. However, the current way of exercising bicycles makes the transmission of power inefficient, so the speed is difficult to improve' and the rider's body is easily fatigued. In the long-term, sports injuries may occur, and it is easy for the father to step on each other. The start of the initial period:: and the body is shaken during the break. V. ;'";" ' . That is to solve the above problem. SUMMARY OF THE INVENTION The present invention is a novel bicycle transmission mechanism. The rider replaces the current circular pedaling with the up and down reciprocating motion, and presses the bicycle seat cushion and the pedal in turn by the gravity of the human body. The opposite direction of the linear sliding rod, the power is transmitted to the front sprocket, through the chain wound in a special way, so that two independent and side-by-side slewing gears, which rotate the rear flywheel to rotate the rear sprocket to make the rear wheel of the bicycle power. The present invention completely utilizes 70% of the human body's gravitational potential energy that originally disappeared on the seat cushion, and also makes 098127855

Form No. A010I Page 3 of 1 page 0982047812-0 201107186 Energy is transmitted as a linear slider, without the loss of 1 – (2/?1) energy caused by the angle caused by the crank, which can be increased by 3- With 4.5 times the power, the following objectives can be achieved: 1. Increase the speed with a larger gear ratio and increase the practical distance of the bicycle. 2. Labor-saving, high-speed and light-duty manpower means can be the first choice for short-term and medium-sized sports, and increase sports opportunities. 3. The lower limbs are stepped on both feet at a better joint angle range to improve ride stability and reduce sports injuries. [Embodiment] [0005] [0006] Next, a preferred embodiment will be further described with reference to the drawings and the drawings, which are further described with respect to the present invention. As shown in FIG. 1, the present invention replaces the current bicycle seat post connection cushion 3 with a linear slide bar 1 having a row of tooth marks. The linear slide bar 2 replaces the current pedal crank and is connected to the side-by-side pedal 4. 2. As shown in Fig. 1, the sliding rod members 1 and 2 are respectively engaged with the front spurs 5 and 6 jins of the upper and lower ones with their scallops, and the chain 7 passes the upper front sprocket 5 and the rear flywheel 8 After the BB shaft gear 9 and 1 〇, the farthing is built, and the Q is below the spur gear 6. This setting causes the seat slide 捍1 to interlock with the pedal slide lever 2. 4 · As shown in Fig. 1, the two gears 卜β axis 9 and 1〇 in Bu and Hushan fans do not affect each other independently but rotate in the same direction. 5. As shown in Figure 2, the upper and lower slide bars 1 and 2 can be set in two ways because of the high demands of the straight s.士土 /, — π卉 has one side of the tooth mark in the same direction or opposite direction. As shown in the figure, when the scallops of the sliding parts are in the same direction, the chain may be connected to 098127855. Form number Α 0] 01 Page / Total 10 pages 0982047812-0 201107186 The path is: starting from the upper front sprocket 5 under the fox, through the inner gear After the rib is corrected on the arc, it is wound to the lower arc, and then it is wound to the upper arc before the lower arc of the front sprocket 6 to the upper arc. After the lower shaft of the outer gear, the lower arc is wound to the upper fox, and the arc on the front sprocket 5 returns to the origin. 7. As shown in Figure 2, when the tooth marks are reversed, the chain may be connected by the following path: starting from the lower arc of the upper front sprocket 5, passing the arc on the inner gear shaft 9 to the lower arc, and then going down the front sprocket 6 The upper arc is wound to the lower arc, and the lower arc of the ββ axis of the right gear is wound to the upper arc, and the arc of the front toothed disc 5 returns to the origin.

8. As shown in the figure - the rear chainring 11 is connected to the rear axle and engages the rear flywheel 8. [0007] Second, the action mode: _ 1. The rider uses the weight to make the sliding bar under the seat cushion 3 slid down, the front sprocket wheel 5 is rotated by force, and the chain 7 is pulled to rotate the inner gear Β_ via the rear flywheel 8 The rear wheel is rotated with the gear 11. The outer tooth Na series has no effect due to the opposite direction of the turn. 2. When the above action occurs, the lower front sprocket 6 rotates at the same time, causing the pedal slide lever 2 to rise. 3. When the slide lever 丨 slides down to the end of its stroke, the pedal slide lever 2 also stops rising. The plate 4 causes the pedal sliding lever 2 to rotate the lower front toothed disc 6, and the outer gear shaft 10 is rotated by the chain, so that the rear flywheel 8 and the rear wheel are as described in the operation mode 1. The inner gear grab shaft 9 has no effect due to the opposite steering. 4. At the same time, the upper front sprocket 5 is rotated in the reverse direction to raise the seat cushion sliding lever 1 and the seat cushion 3. 5. The above four items are a cycle and are repeated. 098127855 The above disclosure is merely a preferred embodiment of the present invention, and the form number Α0101 ^ c - Κ - / Λ - c - page 5 / total ι page 0982047812-0 201107186 is not intended to be the present invention It is intended that the present invention be construed as being limited by the scope of the present invention.
