Definitions
- the present invention mainly uses an ankle force, which has not been used so far, to rotate a crank in a propulsion device such as a bicycle having a rotating crank mechanism powered by a human foot or a training machine. Even in areas where it is difficult to transmit the force of stepping from the top dead center and bottom dead center to raising the crank, the ankle force is used as the rotational force.
- Semi-fixed shoe fixing that can be used as a new bicycle power source by transmitting to the crank, filling the gap of the driving force generated between alternating left and right stepping, and realizing efficient bicycle promotion It relates to the shaft.
- Bicycles are popular as recreation, transportation, and competitive sports, and are popular all over the world. Therefore, in the bicycle industry, various bicycle parts are highly common and constantly improved.
- One of the bicycle parts that has been greatly redesigned is a bicycle pedal device.
- the propulsion device represented by a bicycle by crank rotation shows the highest level of efficiency, and the further improvement of efficiency by the present invention widens the possibility of using the bicycle, improves health by promoting exercise, and improves cars and motorcycles. This helps to improve environmental problems by suppressing energy consumption by transportation means.
- the crank mechanism has a region where the stepping force is not transmitted to the crank at the position where the crank mechanism is lifted from the top dead center and the bottom dead center, which is a big problem in crank rotation.
- the calf muscle has a relatively strong muscular strength due to the structure of the human body, so active use is required for the purpose of increasing running power and jumping power, etc.
- this muscular strength can be used for pedaling It is possible to increase the efficiency of pedaling.
- the object is to prevent the pedal from being removed and to improve the difficulty of pedaling with the toe, but it is similar to the present invention.
- Japanese Patent Laid-Open No. 2004-231136 which is an invention for keeping the pedal body horizontal at all times, is an invention having a solution.
- the movement of extending the ankle from the bent state is important.
- JP-A-2004-231136 In this case, the ankle angle cannot be changed intentionally because the pedal body is always kept horizontal, and the effect is limited.
- the invention has a purpose different from providing an ankle force as a new power source for the rotation of the crank, which is an object of the present invention.
- Japanese Patent Application Laid-Open No. 2-68288, Japanese Patent Application Laid-Open No. 64-28089 which aims to extend the length of the crank by changing the position of depression by preparing a pedal having a plate and utilizing the lever principle,
- JP-A-63-173782 and JP-A-1-182186 are JP-A-63-173782 and JP-A-1-182186.
- the present invention is a very strong calf, but no one has ever thought of a muscle that has not been used on a bicycle so far, but it can be used as a new power source in a very simple way, and so far
- the rotation of the crank due to the depression of the pedal is not hindered, and thus has a remarkable effect of greatly improving the propulsive force of the bicycle.
- the effect of the present invention is simply calculated based on the premise of general muscle strength, the general stepping work is a 150 degree crank with a stepping pressure of 40 kgf, whereas the present invention stretches the ankle.
- the propulsion speed decreases as the effect increases because the actual driving force does not change.
- the speed is extremely reduced, stable operation is hindered, and therefore only has an effect limited under certain conditions.
- the present invention has not been used at all so far, and very strong muscles can be additionally used as a new power source, and the driving force of the bicycle is greatly improved, so that it can be easily climbed even on a slope.
- the effect of improving the driving force such as, the effect of improving the driving speed in the case of speeding up on flat ground is also quite distinctive.
- the conventional crank mechanism has a problem that the muscle strength of the calf, which has a relatively strong force in the human body, cannot be utilized.
- crank rotation position In the conventional crank mechanism, much of the rotational force is obtained by the vertical movement by stepping on the foot, but the crank position is above or below the rotation cycle, and the foot stepping force is not converted to the force to rotate the crank.
- the existence of a crank rotation position called a top dead center / bottom dead center in a possible rotary crank mechanism is a problem in an efficient rotational movement of the crank mechanism.
- Bicycle athletes are required to learn pedaling techniques using knees at the top dead center in order to increase efficiency, but in the normal bicycle standards, the athlete's knees are bent at 90 degrees or more at the top dead center. In this case, an excessive load is applied to the knee joint, which causes a problem of causing muscle and joint fatigue and injury.
- An object of the present invention is to provide a semi-fixed shoe fixing shaft that can be used for crank rotation.
- the semi-fixed shoe fixing shaft has a function of fixing the sole of the foot and the shaft by a bicycle shoe having a clasp generally called cleat and a shaft having a hook for fixing the clasp.
- the shaft is installed so as to be rotatable with respect to the crank. However, by having a ratchet function, the shaft stops rotating in the forward rotation direction of the crank, but can rotate freely in the reverse direction.
- the force to extend the ankle becomes the force to rotate the bicycle shoe and the shaft, and this force is received by the ratchet function and converted to the force to rotate the crank.
- the ratchet is free in the reverse direction and does not hinder the rotation of the crank.
- the ratchet pawl or the ratchet spring is installed so as to be fixed at a position where the ratchet function is invalidated, and the effect of the present invention can be arbitrarily controlled.
- the ratchet control lever By connecting the ratchet control lever to the ratchet spring and slidably installing on the shaft, the ratchet control lever can be operated to arbitrarily control the activation and invalidation of the ratchet.
- the existing crank-fixed shaft can be used as it is by installing a free-rotating base on the shaft and installing a hook for fixing bicycle shoes.
- Multiple ratchet teeth and ratchet claws can be installed, and the position where the effect is exerted can be changed or restricted.
- the force of stepping is not used at all, and only the force of the ankle is used, but it has never been used so far, but mainly on the calf for moving the ankle having a very strong muscular strength in the structure of the human body.
- the muscle can be used as the rotational force of the crank.
- the stepping force is not used at all. Therefore, even a passenger who cannot apply power due to obstacles in the knees and hips can control a bicycle that could not be used by the present invention as long as it can apply power to the ankle. Become.
- the effect of the present invention is a pure improvement of driving force, and using the lever principle to reduce the speed does not lighten the stepping pressure during traveling, so the use of a steep slope without reducing the propulsion speed It also enables traveling with heavier loads.
- the present invention is a pure improvement of driving force, it improves the average speed on flat ground and the maximum speed in competitions. This makes it stand out in all crank-equipped devices, such as conducting competitions on mountain courses that have been difficult for ordinary bicycle riders to challenge, updating the maximum speed of bicycles, and greatly improving the flight distance of human-powered airplanes. It is possible to create effective effects.
- the general stepping work is a 150 degree crank with a stepping pressure of 40 kgf, whereas the present invention stretches the ankle. Assuming that it is possible to add a force to turn a 64 degree crank with a force of 30 kgf, it creates a remarkable effect of improving the propulsive force by 40%.
- FIG. 6 and FIG. 7 show a movement in which the crank position reaches the bottom dead center and the crank cannot be rotated by a normal stepping force, and is lifted from the bottom dead center to the rear rotational position by the effect of the present invention.
- This explanation shows the effect of the present invention near the bottom dead center, but this effect can be exerted at any position of 360 degrees, and it should be carried out at any timing according to the ease of rowing and the situation of the passenger. Is possible. In addition, it can be performed any number of times by bending and stretching the ankle each time.
- Bicycles are stepped on the left and right alternately, and when one foot is at bottom dead center, it is possible to provide driving force even when the other foot is at top dead center. It is possible to realize efficient crank rotation without the moment of disappearance.
- crank part Since the crank part is close to the ground due to the structure of the bicycle, it is easily affected by mud and dust, and dirt such as mud may hinder normal operation of the present invention, so a mudguard cover is attached. It is necessary to devise such as. If mud or the like still enters, it is necessary to clean the inside. In this case, disassembling and cleaning the parts requires complicated procedures such as specialized knowledge and tools. On the other hand, by installing some of the components on the shoe side, it is possible to expose the ratchet claws and ratchet teeth by simply removing the bicycle shoes without disassembling, so that easy cleaning is possible. .
- crank and the shaft are fixed, but the present invention is achieved by installing a rotating base on the shaft and installing a device for connecting with bicycle shoes and a ratchet mechanism there. Can be implemented.
