Regarding a bicycle stand equipped with a mechanism capable of doing so and a bicycle equipped with this.

Generally, a bicycle is provided with a stand for keeping the vehicle body upright when the bicycle is parked. The stand is often attached to the axle of the rear wheel. For example, a one-legged stand or a two-legged stand surrounding the rear wheel is widely known. In addition, in bicycles equipped with child seats and electrically power assisted bicycles, a center stand is also known, which is attached between the crank shaft and the rear wheel when the bicycle is viewed from the side, and the left and right legs are integrally molded.

Conventionally, such a stand has been urged against the legs of the stand in the flip-up direction only by the elastic force of the spring. However, if an attempt is made to hold the legs of the stand in the flip-up position only by the elastic force of the spring, the legs of the stand will rattle when a large external force is applied such as when overcoming a step. As a result, when the legs of the stand return to the flip-up position, an unnecessary impact is generated, which causes a problem of uncomfortable riding. Further, if the aged deterioration of the spring exceeds the assumption, there may be a problem that the legs of the stand cannot be sufficiently held in the flip-up position. Under these circumstances, Patent Document 1 proposes a mechanism for holding the legs of the stand other than the elastic force of the spring.

FIG. 1 is a schematic perspective view of a state in which the legs of the stand according to the preferred embodiment of the present invention are flipped up, and FIG. 2 is an exploded perspective view of the stand according to the preferred embodiment of the present invention. It is a figure. The stand 10 of the present invention shown in the figure has a mounting portion 1 to be attached to a bicycle, a leg portion 2 rotatably attached to the mounting portion 1, and a mounting portion 1 rotatably attached to a position different from the leg portion 2. It has a locked portion 3 and a lock portion 3. The leg portion 2 is rotatable about the rotation shaft 2a, and the lock portion 3 has a structure that is rotatable around the rotation shaft 3a.

Further, in the stand 10 of the present invention illustrated, the locking portion 3b covers the leg portion 2 so that the locking portion 3 locks the leg portion 2 when the leg portion 2 is flipped up. A locking portion 2b is provided. Further, in the illustrated example, the spring 4 which is a tension spring is hooked between the spring mounting portion 3c provided on the upper side of the lock portion 3 and the spring mounting portion 2c provided at the substantially central portion of the leg portion 2. It has been handed over and both are connected. In the illustrated example, the lock portion 3 has a lever-shaped operation portion 3d, and the lock portion 3 is rotated by using the operation portion 3d.

In the stand 10 of the present invention, when the leg portion 2 is flipped up, the leg portion 2 is locked by the lock portion 3, and the leg portion 2 can be held (locked) in the flipped-up state. FIG. 3 is a schematic rear perspective view of the stand according to the preferred embodiment of the present invention when the stand is unlocked in the flipped-up state, and FIG. 4 is a view of the stand according to the preferred embodiment of the present invention. It is a schematic rear perspective view at the time of locking in a raised state. In FIGS. 3 and 4, the mounting portion 1 and the spring 4 and the like are omitted for simplification.

In the example shown in FIG. 3, the locked portion 2b provided on the upper end side of the leg portion 2 is a concave portion that opens upward and becomes concave downward when the leg portion 2 is flipped up. 2b. Further, a cam follower 3b is arranged in the lock portion 3 as a locking portion 3b, and the cam follower 3b can advance and retreat in the recess 2b. That is, when the operation unit 3d is rotated clockwise, the cam follower 3b moves downward, and as shown in FIG. 4, the cam follower 3b enters the recess 2b provided at the upper end of the leg portion 2. As a result, the rotation of the leg portion 2 is restricted, and the leg portion 2 can be prevented from rotating in the upright direction. Further, when the leg portion 2 is in the state of being locked to the lock portion 3, the cam follower 3b provided on the lock portion 3 moves upward by rotating the operation portion 3d counterclockwise, and the leg The locked state with the unit 2 is released. As a result, the leg portion 2 can rotate.

In the illustrated example, a cam follower 3b is arranged as a locking portion 3b in the lock portion 3, a recess 2b corresponding to the cam follower 3b is provided in the leg portion 2, and the cam follower 3b is allowed to enter the recess 2b to allow the leg portion 2 to enter. Although the structure is such that 2 is locked by the lock portion 3, in the stand 10 of the present invention, the means for locking the leg portion 2 by the lock portion 3 is not limited to this. For example, the lock portion 3 may be a convex portion corresponding to the concave portion 2b of the leg portion 2 instead of the cam follower 3b, or a pin-shaped member, a roller, or the like may be used as the locking portion 3b.

In the stand 10 of the present invention, the locking portion 3b provided on the locking portion 3 is preferably a cam follower 3b as shown in the figure. By using the cam follower 3b as the locking portion 3b, the operation becomes smooth when the locking portion 3b enters the recess 2b or when these locked states are released. Therefore, the work of holding and releasing the flipped-up state of the leg 2 of the stand 10 becomes smooth.

In the stand 10 of the present invention, the leg portion 2 and the lock portion 3 are further urged by the spring 4. FIG. 5 is a schematic side view of the stand according to the preferred embodiment of the present invention when the stand is locked, and FIG. 6 is a flip-up state of the stand according to the preferred embodiment of the present invention.

As described above, in the stand according to the preferred embodiment of the present invention shown, the spring mounting portion 3c provided on the upper side of the lock portion 3 and the spring mounting portion provided at the substantially central portion of the leg portion 2 are provided. The portion 2c is connected by a spring 4 such as a tension spring.

The spring 4 is attached so that the axis L of the spring 4 exceeds the rotation axis 2a of the leg 2 when the leg 2 rotates from the upright position to the flip-up position in the side view of the stand. With such a configuration, when the leg 2 is flipped up, the leg 2 is rotated counterclockwise, and when the axis of the spring 4 exceeds the rotation axis 2a of the leg 2 in the side view of the stand. , The leg 2 automatically pops up. That is, the urging force of the spring 4 causes the leg portion 2 to rotate counterclockwise, and the lock portion 3 to rotate clockwise. As a result, the locking portion 3b in the illustrated example locks the locked portion 2b, and the leg portion 2 is locked. On the contrary, when the leg 2 is erected, the leg 2 is rotated clockwise, and when the axis of the spring 4 exceeds the rotation axis 2a of the leg 2 in the side view of the stand, the urging force of the spring 4 is obtained. As a result, the leg 2 rotates clockwise, and the leg 2 automatically stands upright. The spring is not limited to the tension spring as long as it has the same action as the above action.

FIG. 7 is a schematic side view of the stand according to a preferred embodiment of the present invention when the stand is locked. In the stand 10 of the present invention, when the leg portion 2 is flipped up, the leg portion 2 may be locked by the lock portion 3 so that the leg portion 2 may be held in the flipped-up state.

(Clockwise in FIG. 7) is preferably the opposite. Similarly, when the leg portion 2 is locked by the lock portion 3, the rotation direction of the lock portion 3 (clockwise in the example shown in FIG. 6) and the rotation direction of the leg portion 2 (in the example shown in FIG. 6). , Counterclockwise) is preferably the opposite. When the locked state of the leg portion 2 and the locked portion 3 is released, if the rotation direction of the leg portion 2 and the rotating direction of the locked portion 3 are the same, the lock portion 3 and the locked portion 3 are released when the locked state is released. This is because the leg portion 2 may rotate.

In this regard, in the stand 10 according to one preferred embodiment of the present invention, when the leg 2 is locked in a flipped-up state, the leg 2 is rotated clockwise in the upright direction. If this is to be done, the left side of the side wall (see FIGS. 2 to 4) forming the opening of the recess 2b will press the cam follower 3b. At this time, if the rotation direction of the leg portion 2 and the rotation direction of the lock portion 3 are the same, the leg portion 2 and the lock portion 3 may rotate at the same time. However, in the stand 10 according to one preferred embodiment of the present invention, the direction in which the left side wall of the recess 2b tends to rotate the cam follower 3b is different from the direction in which the cam follower 3b is rotated. No problem occurs.

In the stand 10 of the present invention, when the locked state of the leg portion 2 is released by the lock portion 3, the axis L of the spring 4 exceeds the rotation shaft 3a of the lock portion 3 in the side view of the stand, but the leg portion It is preferable that the rotation shaft 2a of 2 is not exceeded. As shown in FIGS. 6 and 7, when the locked state of the leg portion 2 is released by the lock portion 3, the axis L of the spring 4 exceeds the rotation axis 3a of the lock portion 3 in the side view of the stand. , It is possible to prevent the lock portion 3 from returning to the state of locking the leg portion 2 due to the urging force of the spring 4, and the axis L of the spring 4 is the leg portion 2 in the side view of the stand. By not exceeding the rotation shaft 2a, it is possible to prevent the leg portion 2 from automatically rotating to the upright position due to the urging force of the spring 4. Although not shown, the same applies when the lock portion 3 releases the locked state of the leg portion 2 while the leg portion 2 is in the upright position.

In the stand 10 of the preferred embodiment shown in the present invention, the legs 2 are locked by the lock 3 even when the legs 2 are in the upright position. In the example shown in FIG. 2, the leg portion 2 has a recess 2b into which the cam follower 3b of the lock portion 3 enters when the leg portion 2 is flipped up, and the lock portion 3 when the leg portion 2 is in the upright state. It has a second locked portion 2e that is locked by the second locking portion 3e. In the illustrated example, the second cam follower 3e of the lock portion 3 has a structure that allows the second cam follower 3e of the lock portion 3 to enter the second recess 2e of the leg portion 2. The concave portion 2b and the concave portion 2e, which are locked portions, are connected by a convex curved portion 2f.

When the leg portion 2 is brought into the upright state, the lock portion 3 is rotated counterclockwise, and when the axis L of the spring 4 exceeds the rotation axis 3a of the lock portion 3, the lock portion 3 is counterclockwise by the spring 4.
