Description of the invention;) [Technical Field] The present invention relates to a crank shaft and a part of a bicycle driving device. The length between the pedals λ is freely changed by the orbital movement of the eccentric driven element. * It becomes longer in the part where the pedaling force is applied. * It becomes shorter in the part where the pedaling force is not necessary. However, there is no telescopic member, which forms a smooth crank and pedal. As the orbit is almost a circular track, it is suitable for increasing the driving force without a sense of misalignment; it is mainly an eccentric crank made of gold. [Background Art] It is known from the past that a pedal is mounted on a rod-shaped tip made of a metal material called a crank through a pedal shaft, and is a driving device that forms a rotary motion around the crank shaft. Such a crank is, for example, a device that can be changed to a rotary motion by applying the pedaling force of a foot, and the large gear that is linked is used as a component that drives the chain, the pinion, and the rear wheel in order. In addition, in addition to being used as a component of such a driving device, the crank can be used as a component for changing the linear motion of a work machine or an engine into a rotary motion. It is used in many ways = for example, in the case of stamping machinery, it is used as a The rotary motion of the crank is changed to a linear motion. In addition, engines are used for the purpose of changing the linear motion of the piston to a rotary motion by applying pressure to the crankshaft side. These cranks are formed by a crank shaft and a crank pin. The orbit of the crank pin centered on the crank shaft, the length from the crank shaft to the crank pin is increased by linear motion. Formation under energy is an important decision-making means. --- · ------- install ------ order ------ · " '(Please read the note on the back before writing this page) SK home in this paper standard榡 中. ≪ rNS > Λ4 present < 210X297 mm > 414777 A7 __ _B7_ V. Description of the invention) In bicycle cranks, the pedal shaft is used to form a crank pin, the longer the length from the crank shaft to the pedal shaft The longer the pedaling force of a foot, the greater the propulsive force. "However, | the length of this crank is too long, which will cause the foot to press the pedal harder, increasing the amount of foot movement, and excessively exhausting physical strength. In addition, if the length of the crank is too short, the foot will be too heavy, which may cause foot fatigue. For these reasons, the length of bicycle cranks that are widely used is generally set to an appropriate length according to the rule of thumb for long pieces. In addition, in addition, the arm of the crank is extended and retracted, and it is extended too long when pedaling. However, in this case, because the arm of the crank is extended and contracted, the turning track of the pedal shaft is not a completely circular track. It is a deformed track, and it has the disadvantage of the foot's turning motion causing a sense of imbalance. Furthermore, the telescopic mechanism does not operate smoothly: the number of components constituting the telescopic mechanism increases, and there is also a problem of non-economical aspects. In addition, the track of the most widely used crank and pedal shaft is formed at a certain distance from the center of the crank shaft, so the length between the pedal shaft and the crank shaft also holds the same length at any position. The reason for this structure is that when the foot is exerted with a pedaling force, or when the foot is pulled up, the length is always the same. It is not possible to increase only the part where the pedaling force is required, and shorten the part where the pedaling force is not required. That is, when pulling up a foot that does not require pedaling force, the length between the crank shaft and the pedal shaft will be shortened, and the radius of motion of the foot will be reduced, thereby reducing physical exertion, or increasing and changing the crank shaft to the part that requires pedaling force to The shortcomings of the pedal shaft, which makes it very large to increase the pedaling force, ca n’t be performed β. That is, half of the track of the rotary pedal shaft is the part that applies the pedaling force, and the other half is formed as a foot pull. -Install ------ ΐτ ------ {Please read the precautions on the back ^; write this page) SR3 homes in this paper size ((, NS) Λ4 specifications (2 丨0 × 297 mm) -5- A7 414777 ___B7_ V. Description of the invention 6) Part "This structural reason has the disadvantage of consuming the amount of movement of the foot when it passes half of the circular orbit. (Please read the precautions on the back before filling this page) Therefore, the purpose of the present invention is to provide the disadvantages of the crank shaft in the past. In the part where the pedaling force is necessary, the growth and change between the crank shaft and the pedal shaft can be increased to obtain a larger The eccentric crank can reduce the amount of movement of the foot when the propulsion force is pulled up and the foot is pulled up, which can shorten the change between the crank shaft and the pedal. In addition, the object of the present invention is to provide a sense of misalignment because the turning track of the pedal shaft is a completely circular track. The size of this track is within the range of the previous track size, and since the telescopic mechanism is not used, the smooth movement is formed. The length change caused by the revolution of the driven element makes it increase the stability of the propulsive force and complete the higher eccentric crank. [Indication of the invention]

However, this pedal track is positioned from the crank shaft to the front, so that the center position of the track has a crank shaft on the X-ray rear. And the establishment of innovative technologies that can form almost completely circular orbits. Furthermore, when the pedal shaft reaches the 12 o'clock position in the clock direction * because the straight angle connecting the crank shaft and the pedal shaft has been tilted to the front, even if the angle of the pedal is changed, it can be added in an almost horizontal state. Characteristics of pressure. That is, more than half of the almost circular track drawn when the pedal shaft rotates around the crank shaft is formed as the area of the pedal, and the remaining half is formed as the area of the foot pull. Furthermore, the ratio of the pedal portion to the pull-up portion is formed so that the ratio is determined by the set point of the pedal shaft at an eccentric portion that is deviated from the center of the driven element, by the amount of eccentricity. That is, the track of the same size as in the past can be freely changed from the crank shaft to the pedal shaft according to the eccentricity from the driven element to the point where the pedal shaft is installed; if necessary, set this The amount of eccentricity is sufficient. The necessity of these is, for example, that when the position of the pedal shaft is set at the eccentric position of the track of a radius of 170 mm from the center of the driven element to 8.5 mm, the propulsive force of the bicycle is increased by about 4 at most. 8%; the calculated result is the largest increase of 5%. Furthermore, by increasing / decreasing the eccentricity 'in a suitable range, the necessary pushing force can be adjusted. The appropriate range is from the center of the driven element to the radius.

It characteristics, it is indeed different from the previous crank, for example, when the pedal shaft is set from the center of the driven element to 8.5 mm, the pedal shaft of the right crank is based on the actual measurement at the time point of 12 o'clock The position gets a propulsive force increase rate of 1.25%; at a time point of 1 point, a propulsive force increase rate of 2.5%; at the 2 o'clock point, a propulsion force increase rate of 3.75%; at 3 At the time point, the propulsive force increase rate of 5% is obtained. In this measurement example, the distance from the crank shaft to the center of the driven element is 17 Omm. The center of the pedal shaft is set to 8.5mm. As a result, the orbital diameter of the orbital pedal shaft is 3 40mm: the longest fulcrum from the crank shaft to the pedal shaft is 178.5mm, and the shortest fulcrum is 161.5mm " The mechanical resistance of the bicycle is less than 1%, so it is easy to display the maximum increase in propulsion force, and it has characteristics suitable for the purpose of reducing the burden on the foot.

Description of the invention b) The first picture is shown in the crank 1 The unit 2 of the front end receiving end effector 3 is directly made at the front end of the crank 1. The figure of the eccentric crank according to the present invention is installed, but to make it easy to understand this embodiment, the upper part of FIG. 2 is used. And the figure below. The overall shape of this eccentric crank is the same shape as the swollen right crank that has a cylindrical shape at the tip of the crank. However, these materials are made of steel, stainless steel, aluminum, and other strength materials. At the front end of the crank, a cavity capable of accommodating the driven element 3 of a preset size is set; the bearings 5 and 6 are inserted and inserted from both sides to form a structure of the driven element 3 with an inner diameter closely contacting the inside. . According to the lower diagram of this second figure, the shape of the track changed during the revolution of the pedal shaft 4 a indicates the position at which the upper dead point and the lower bottom dead point of the pedal shaft 4 a are reached. There is no change from the previous crank characteristics, but the distance between the crank shaft 1 and 4 is different from the crank shaft 1 to 4 at the 3 o'clock position and the 9 o'clock position of the pedal shaft 4 a. The reason for such different-length tracks is that the driven element 3 and the pedal shaft 4 a are fixed and integrated, and the center pedal shaft 4 a of the driven element is caused by the revolution of the driven element around the revolution crank shaft 1 4. The result of movement in and out of the inside. In addition, regarding the third figure, it is made of a rod-shaped metal material, and crank shaft holes 1 4 a and driven element storage single redundant pieces 2 are provided on both sides. Among them, the driven element storage unit is also manufactured differently from the crank arm. A means for mounting the produced single element, but here will be described using a case of integration in order to make the drawing easier to understand.

Description of the invention) In addition, regarding the fourth figure, the plan view of the driven element 3 and the broken chart are shown. Figure: There are two sets of driven Element and 1 set of driven elements: Here, 2 sets of driven elements # are used for description. This driven element 3 is formed by processing the metal material, and the bearings 5 and 6 are embedded into the driven element unit 2 from both sides. The driven element fixing bolt 9 a is screwed and freely inside the unit. The ground is constructed. Furthermore, an octagonal pedal shaft 4a is provided at an eccentric position deviated from the center of the driven element 3, and the pedal shaft 10a is inserted so as not to cause idling. In addition, the entire system of FIG. 5 is a view in which the components constituting the eccentric crankshaft are disassembled and expanded. Among them, the pedal shaft 10 a and the pedal 13 are inserted through the pedal shaft hole 1 0 b, and the lock pin 1 2 is inserted through. a is fixed and has a structure in which the driven element 3 and the pedal 13 are integrated. Further, Fig. 6 is a sectional view of the assembled state of the crank. As shown in this figure, the structure that does not return to the position between the pedal 13 and the pedal shaft 10 a and the member that is rotated inside the driven element unit 2 is shown. In addition, FIG. 7 is a diagram showing a comparison between the track of the pedal shaft 10 a of the eccentric crankshaft and the turning track of the pedal shaft in the past. As shown in this figure, the pedal shafts representing the circumference of the orbiting crank shaft 14 are different from each other. This orbit is an orbit indicated by a dotted line of 20 a, and the orbit of the past type is a line of 2 1 a. Looking at these two tracks precisely at each position of the pedal shaft, it means that the 12 o'clock position and the 6 o'clock position in the clock direction are on the same line: this result indicates that the up and down movement range of the foot is unchanged from the past In addition, for the track center of the past type, which has a crank shaft 1 4, the track has no crank shaft 1 4 at the center position and --'-- ^ ----- installation ------ order ----- -Brigade (read the note on the back ^^ Item #, also write this page) The paper size gfS family standard in Zhouzhou (<, NS) Λ4 size < 210χ 297 mm) -11-414777 A7 A 7 _B7_ V. Description of the invention) It is easy to distinguish if it deviates in the direction of 3 o'clock. That is to say, this picture is an example of the right crank of a bicycle, so from the crank shaft 1 4 the longest part in the front and the shortest part in the rear. Based on the comparison of the integrity of the two tracks, the obtained system is the part added from the time point of 12 o'clock to the time of 6 o'clock. The difference from the length of the crank shaft 14 is as shown in the proof. The principle is a face of length, so this longer component increases the order force than the previous type. In addition, when comparing these two tracks, it is possible to easily check that the track on the crank shaft 14 is shorter than the track of the conventional type by precisely inspecting the upper and rear parts of the crank shaft 14. It can be understood from this comparison that certification can be shown that reducing the radius of motion of the foot pull can be achieved, so the physical exertion can be reduced. Furthermore, Figure 8 is a graph showing the distance from the crank shaft to the pedal shaft at each time point. It is shown that the position of each time point increases or decreases at the same interval. This situation is only formed for the past track. A line on line C. The track has the width of the interval B that is reduced to a length of the increase interval A: changing the length between the crank shaft and the pedal shaft between this amplitude, indicating the part that is conducive to its action. And the part that does not require pedaling force, resulting in an increase in torque and increased propulsion. Fig. 9 is a diagram showing a past type. As described above, the results of the test performed to demonstrate the effects of these torque increases are specifically shown and suggested below.

Description of the invention C | 2) The number of teeth, (<) is the length from the crank shaft to the pedal shaft '(τ 1 ) Is the number of large gear teeth, (R) is the radius of the rear wheel; substitute the respective numbers in this symbol, and the result is #. In addition, the actual measurement is for a bicycle with a conventional crank and a bicycle with a right crank. On the test bench, the right pedal is set at 3 o'clock in the clock direction, and the load is applied to this pedal in an overlapping manner. The pressure of the back wheel torque is measured to determine the result of the test. [Industrial Applicability] As described above, the eccentric crankshaft of the present invention can be used in fields other than a component of a bicycle driving device for the purpose of increasing the torque of a mechanism that changes linear motion to rotation, and is particularly applicable. This is a mechanism for competitive bicycles. Except for bicycles, this mechanism is the part that changes the reciprocating action of linear motion of the engine to a rotary motion. It can deviate from the crank shaft to the track of the turning track formed by the crank pin. : This track produces the longest field and the shortest field from the crankshaft, so distinguishing and using this different field can achieve the purpose of saving energy or increasing power. Such a mechanism does not have the structure of a telescopic member, and has the effect of changing the length: it has a structural feature that resists heavy pressure and is therefore suitable for mechanical structures. Furthermore, most of the past mechanical structures use a reduction gear to increase the power at a ratio of the relative amount of motion, and increase the amount of motion on the prime mover side during deceleration. Therefore, fuel consumption and physical energy cannot be avoided. However, because this mechanism can increase the movement without increasing the amount of exercise, it can also be applied to the KS family standard rate (('NS) Λ4 specification (210X297 mm) in the use of working papers) -15- 414777 A7 __B7_ V. Invention Note b) Machinery or engine or pump machine. Therefore, this eccentric crank provides an innovative device that can fundamentally change the control mechanism using a reduction gear: b, an increase in the mechanism of the past general mechanical theory, so it can save energy or significantly reduce the fatigue of cyclists. New technologies can be used in many areas of the industry. Please read the notes and notes on the back of this book.
