Description

[Detailed explanation of the invention] In this invention, when the stop lever is moved from the flipped up position to the upright position, the locking pawl of the lock plate simultaneously engages with the engagement recess of the board to prevent the stop stick from moving. In addition, when the stop lever is to be flipped up in a locked state, the lock plate is activated and the lock claw is released from the notch in the base plate, and the stop lever is also raised at the same time. Regarding the stand of the device.

In conventional stands, the operation of the stop lever and lock plate is performed in two stages, which is inconvenient as it takes a lot of effort to flip up, park, and lock the stop lever. This proposal was made with the aim of resolving this inconvenience.

The present invention will be explained below with reference to the embodiment shown in the drawings. 1 is a board to be attached to the vehicle body, and the upper end 4 of the stop lever 3 is pivoted 5 between the support piece 2 bent to the rear side and the board. The stop lever is connected to a board, and a bearing 6 whose axis is offset by a required distance from the central axis of the stop lever is attached to a predetermined position at the rear near the upper end 4 of the stop lever, and a lock plate 7 is attached to this bearing. The upper end of the lock plate is formed into a required curved edge, and curved edges 9 and 10 bent toward the back side are provided at both ends. A cutout recess 12 for engaging and disengaging the lock pawl 11 is provided on one lower side of the board 1, and a stopper 13 of the stopper rod is formed at the lower end of the board below where the cutout recess is provided by bending the edge toward the back side. However, the lower rear end of the substrate connected to this stopper part is formed into a guide edge having a cam-shaped protrusion 14 at a predetermined position in the middle, and a locking step part 15 of the stop lever 3 is provided at the rear end to lock the lock plate. The cut-out claw 16 provided on the front of the lower end of 7 and the substrate 1
Both ends of a coil spring 18 are hooked to a fixed protrusion 17 provided at a predetermined position on the front side of the bicycle stand, in the same way as a normal bicycle stand.

Since the present invention is configured as described above, when the stop lever 3 is erected, the lock plate 7 is
When the lock plate 7 moves to the state shown in the figure, the lock pawl 11 engages with the cutout recess 12 and the axis of the coil spring 18 is located forward of the axis of the stopper rod, so the engagement between the lock plate 7 and the base plate 1 is stable. Therefore, the stand-up lever is stable and there is no fear of it jumping backwards on its own. If the stop lever is to be flipped up, the lock plate 7 can be pivoted rearward about the support shaft 8, and the lock pawl 11 will be released from the notch recess 12, and at the same time, due to the action of the coil spring 18, it will be lifted up as shown in FIG. The lock plate rotates as shown by the dotted chain line, and at this time, the upper ends of the curved edges 9 and 10 provided on both sides of the upper end of the lock plate are
It rotates along the arc-shaped guide edge with a cam-like protrusion on the lower end of the board, and the stop rod 3 hits the locking step 10 and stops, and the coil spring stabilizes in the state shown in Fig. 3 and stops. Hold the rod 3 in its raised position.

When you place your foot on the stop lever 3 and rotate it downward around the support shaft 5, the lock plate 7 also rotates at the same time.
First, when the lock plate is rotated to the state shown by the two-dot chain line in FIG.
collide with Therefore, the upper end of the lock plate 7 cannot rotate any further, but the stop lever 3 rotates further around the support shaft 5, so the lock plate 7 rotates around the curved edge 10 and the support shaft 8. and is rotated to the state shown by the one-dot chain line in FIG.

Here, the stop lever 3 hits the stopper 13 and stops. At this time, the lock plate 7 is further rotated by the action of the coil spring 18 to the state shown by the solid line in FIG. lock.

As described above, in this case, by one operation of the lock plate, the stop lever can be flipped up, and when the stop lever is lowered, the lock plate can automatically rotate and be stopped in the locked state. For flipping up, you can first unlock the lock plate and then raise the stop lever without having to perform the two-step operation, because it is a one-touch operation. This has the effect of conveniently allowing the stop lever to be stopped and raised.
