Description of the Invention [Technical Field] The present invention relates to a mounting device for a bicycle footrest. [Prior Art] A conventional bicycle pedal is provided with a thread on a pedal shaft and a pedal crank, and is fixed by tightening both. With this configuration, a technician who does not have bicycle repair technology cannot install the foot pedal. However, in recent years, bicycle sales channels have been moved to mass shops other than bicycle stores, but for mass merchandisers, it is expected that such technicians are not required. It is expected that even a mail order (or online shopping) method can be shipped in a state in which the foot pedal is removed (decomposed), and a general consumer who does not have the technology can also install the foot pedal. Moreover, the player of the bicycle may exchange the pedals in accordance with the use conditions. However, the loading and unloading of the conventional footrest requires a foot pedal that can be easily attached and detached because tools and time are required. In order to solve such a problem, the applicant has previously proposed a mounting device for a foot pedal that does not require a tool (Japanese Patent Laid-Open No. 2000-289680). This invention has the following structure. Combination: a receiving device mounted on a pedal shaft mounting hole of a pedal crank, and a pedal shaft having an annular locking recess for locking the locking body on the outer circumference, wherein the receiving device is: a bolt collar having an inner diameter equal to the outer shape of the pedal shaft, a locking body attached to the through hole formed in the bolt collar, and a stopper slidably mounted on the outer side of the bolt collar The collar constitutes -4- 1378882. The stopper collar is an annular stopper convex having a state in which the locking body is pressed toward the central axis direction of the bolt collar and the locking body is locked to the pedal shaft. a spring is disposed between the bolt collar and the stopper collar, and the spring pushes the stopper collar toward the crank 'axis direction, and releases the stopper collar in the direction of the pedal The locking body and the locking recess are locked. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2000-289680 (Explanation of the Invention) (Problems to be Solved by the Invention) In the above prior art, the stopper collar is urged toward the crank side by the spring 'in this state. Although the body is maintained in the state of being locked to the pedal shaft, the regulation of the movement of the stopper collar toward the pedal side is because only the spring is used, so when there is an unrecognized force, the stopper collar may It will move toward the side of the pedal, and as a result, the pedal may fall off. φ The present invention has the same basic structure as the above-described prior art, but it is possible to eliminate the problem that the foot pedal is detached due to unrecognized force. (Means for Solving the Problem) The footrest mounting device of the present invention is a combination of a receiving device attached to a footrest shaft mounting hole of a pedal pedal, and a card holder for locking on the outer circumference. The structure of the pedal shaft that locks the recess. The socket is composed of a bolt collar having an inner diameter equal to the outer shape of the pedal shaft, and a locking-5-1378882 body attached to the through hole formed in the bolt collar, and slidably It is composed of a stopper collar installed on the outer side of the bolt collar. An annular stopper projection is provided in the stopper collar, and the locking body is pressed toward the central axis direction of the bolt collar and holds the locking recess of the pedal shaft in the pedal shaft. In the state, a spring is disposed between the bolt collar and the stopper collar. The spring is disposed to urge the bolt collar and the stopper collar in a direction away from the direction or in the pulling direction, and to impart a rotational direction therebetween. A protrusion is provided on an outer side of the bolt collar, and a groove for moving the protrusion in the axial direction is provided in a peripheral wall of the stopper collar, and the stopper collar is rotated to make the positions of the groove and the protrusion coincide with each other (alignment). The locking of the locking body and the locking recess is released by sliding the stopper collar. It is preferable that the aforementioned locking body is a sphere (the second item of the patent application). The above-mentioned locking body is preferably a spherical body, but can be used in a form that can be inserted into a through hole formed in a bolt collar and can be locked to a locking recess of the footrest shaft. Further, the number of the through holes or the locking bodies is plural, and in particular, when the locking body is a sphere, four or more are preferable, but the number is not limited. Further, the groove formed in the axial direction of the stopper collar may not be formed in a slit shape, but a groove through which the projection of the bolt collar can pass may be formed inside the peripheral wall of the stopper collar. The rotation angle of the bolt collar and the stopper collar generated by the spring is preferably 90 degrees, but is not limited thereto. Further, the direction in which the spring is urged in the axial direction is such that the bolt collar and the stopper collar are urged in a direction away from the direction of the -6-series 8882 shown in the embodiment, and both directions are drawn. The way of pushing. In the latter case, the stopper collar is locked to the locking groove of the footrest shaft while the stopper collar is pulled toward the bolt collar side, and the stopper collar is attached to the pedal when the pedal is attached or detached When the pedal side is pulled, the locking of the locking body can be released. (Effect of the Invention) The footrest mounting device of the present invention is used in a state in which the socket is attached to the bolt hole of the crankshaft. In other words, when the vehicle is shipped from a bicycle factory or the like, the adapter is attached to the crankshaft, and the shoe is attached to the crankshaft in a state where the adapter is previously attached to the crankshaft. Rotate the retainer collar of the adapter to align its groove with the protrusion of the bolt collar and then slide the stopper collar. At this time, since the locking body is released from the concave pressure of the stopper projection, the pedal shaft can be inserted into the socket without hindering the locking body. Then, when the hand is released from the stopper collar, the stopper collar is moved toward the pedal side by the force of the spring, and the locking body is pressed by the stopper convex portion toward the locking recess of the pedal shaft. The foot pedal is fixed. Therefore, the foot pedal can be fixed by the same conditions without using a tool and regardless of whether or not there is a technique. Further, the pedal can be removed by releasing the lock of the stopper by sliding the stopper collar. Therefore, it becomes a mounting device that can be attached and detached without installing technology and can be easily attached and detached. Moreover, the stopper collar is held in the locked state by the spring, and since the stopper collar does not move without opposing the spring and rotating the stopper collar, the bicycle walking can be eliminated even with a relatively simple structure. When the pedals fall off. 1378882 [Embodiment] As shown in Figs. 1 to 6, the pedal recess 1 of the footrest A is formed in a ring shape by the locking recess 2, and the locking recess 2 is detachably locked to the pedal. The socket 4 is fixed to the pedal crank 3, and the footrest A is fixed to the pedal crank 3. The specific structure of the aforementioned locking body is as follows. A mounting hole for mounting the footrest shaft is disposed at a front end portion of the pedal pedal 3, and an inner wall of the mounting hole is provided with a thread groove, and the thread groove is a cylindrical body, that is, a bolt collar 5 The thread groove 5a of the outer wall of the base is screwed, and the footrest A is attached to the pedal crank 3. In the peripheral wall of the bolt collar 5, four through holes 7 for attaching the locking body 6 are formed at equal intervals on the same circumference, and the locking bodies 6 of the spherical bodies are separately provided in the through holes 7 of these. . A stopper collar 8 is attached to the outer side of the bolt collar 5 described above. In the pedal side of the stopper collar 8, in order to press the locking body 6 toward the locking recess 2 side of the footrest shaft 1, an annular and small-diameter stopper projection 9 is formed, and the stopper is stopped. The footrest side of the convex portion 9 is a large-diameter portion 10 having a play for releasing the locking body 6 from the locking recess 2. The size of the large diameter portion 1 is such a size that the locking body 6 does not fall off the through hole 7 of the bolt collar 5 when the stopper collar is slid toward the crank side. The bolt collar 5, the locking body 6, and the stopper collar 8 constitute the socket 4 ^. The projection U is provided on the thread groove side of the bolt collar 5, in order to stop the 1378882 of the crank collar of the collar 8 The peripheral wall allows the stopper collar 8 to move in the crank direction, and the groove 12 in which the projection 11 can move in the axial direction is disposed with a coil spring 13 between the bolt collar 5 and the stopper collar 8. The bolt collar 5 and the stopper collar 8 are urged in the distal direction by the spring 13, and a rotational force (90 degrees) is applied therebetween. Further, by the force of the spring, in the normal state, the stopper collar 8 is such that the stopper convex portion 9 is pressed against the locking body 6 at a position corresponding to the locking body 6, so that the locking body 6 becomes The locking recess 2 of the pedal shaft is locked, and the projection 11 of the bolt collar 5 is locked to the crank side end edge of the stopper collar 8. The stopper collar 8 is rotated by 90 degrees and the groove 12 formed on the peripheral wall of the stopper collar 8 is aligned with the position of the stopper pin 11, and is stopped by pressing the stopper collar 8 toward the crank direction. The collar 8 is moved in the axial direction, and by moving the stopper projection 9 from the corresponding position of the locking body, the concave pressure of the locking body 5 is released. Hereinafter, a method of using the mounting device of the present embodiment will be described. When the footrest A is attached, the stopper 13 is rotated against the spring 13, and when the position of the projection 11 and the groove 12 is fitted (aligned) and pressed toward the crank side, the stopper stage portion 9 of the stopper collar 8 will be Moving toward the crank side releases the pressing of the stopper body 5 of the stopper stage portion 9. In this state, the footrest shaft 1 is inserted into the bolt collar 5, and then the hand is released from the stopper collar 8 to return to the original position by the force of the spring 13, the locking body 5 is stopped by the stopper 9 The pressing recess is locked to the locking recess 2 of the pedal shaft. When the footrest A is removed, in the same manner as described above, after the presser stopper collar 8 releases the pressing body-9-1378882 5, the pedal shaft 1 can be pulled out. If the pedal is not rotated and pressed into the two-stage operation of the stopper collar 8, the locked state cannot be released. That is, the force in the axial direction and the force in the rotational direction are simultaneously required. Moreover, since the force of the two directions is unrecognized by the preset force, the foot pedal mounted by the device is not easily peeled off due to an unrecognized force during use. [Industrial Applicability] According to the present invention, the spring that is disposed between the bolt collar and the stopper collar has both the axial force and the rotational direction force therebetween. When the foot pedal is installed, it is necessary to apply the above two directions of force at the same time. Therefore, it is possible to provide a mounting device for the footrest which is capable of dissolving the foot pedal due to the unrecognized force and which is easy to handle and safe, and which is industrially usable.
