Abstract

PROBLEM TO BE SOLVED: To improve a user's convenience at a conventional cost by reducing work by half to solve inconvenience when the user is in a hurry because of requiring a total of four-process work of stand setting-up and locking when parking, and unlocking and stand putting-back work when starting to run in conventional bicycle structure. SOLUTION: Four-process work of locking, unlocking, lock execution and release is reduced by half to two processes by improving and interlocking the structure and function of a lock and a lock lever. If the structure and installation place of the lock are altered to constitute the lock lever to be fixable by the lock, the stand remains standing to impede travel unless unlocked with a key, and an effect of theft prevention can be expected without projecting a protrusion between spokes or using a wire to impede the rotation of a wheel like a conventional lock. This device therefore provides a system of locking simultaneously using a part of leg power in stand locking work and releasing the lock automatically by a spring only by unlocking with the key when starting to run again.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a bicycle lock structure.

[0002]

2. Description of the Related Art A conventional general bicycle parking stand is connected to a frame via a bracket at a position near a rear wheel axle. On the other hand, the anti-theft lock is installed on the frame at another place, and the rear wheel or the front wheel has a protruding portion to prevent rotation of the wheel. There is also a wire type. Therefore, stand stand and lock, and unlocking and stand raising work need to be performed as separate works. Recently, there is also a method in which the mounting angle of the saddle is changed when parking a bicycle, and a small double-sided stand provided at the lower center of the bicycle is locked in conjunction with a wire.

[0003]

In the case of a bicycle having a generally employed structure, a total of four operations including a stand operation and a locking operation when the bicycle is parked, and an unlocking operation and a stand return operation at the start of traveling. I need it. If this operation can be halved to two operations, the convenience will increase when the user is in a hurry such as commuting to work or school. In addition, the structure, mounting position and function of the conventional stand are kept as they are, and it is in the user's interest if the price is reduced to the same level as before or below. Therefore, a mechanism that can solve both of these problems is provided.

[0004]

Means for Solving the Problems Normally, when parking a bicycle, the stand is set up and locked for safety, so if the work is used and the lock is not released at the same time, it will not be possible to run, only the unlocking work The necessary operation can be reduced by half if the lock is automatically released. Therefore, the position where the lock is attached is moved closer to the stand to combine the functions of both, and the work of locking and locking the stand when parking the bicycle and unlocking and unlocking at the start of traveling is performed once each at the same time. Make it possible by operation. The manufacturing cost is a small modification of the conventional parts and there is also the benefit of integration, and the price is lower than that of the conventional product, and all the problems are solved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will be given based on an embodiment. There are two types of bicycle stands, one for both sides and one for bicycles. FIG. 1 shows a first embodiment of the present invention applied to a double-standing stand. Bicycle is frame 1
Then, the double support stand 2 rotatably connected to the stand shaft 5 mounted on the bracket 8 fixed via the rear wheel axle 17 is rotated clockwise in FIG. To fix the stand, the lock lever 3 rotatable around the lever rotation shaft 4 installed on the stand 2 is kicked in with a foot, and a holding claw 7 having a tip projection 9 projecting from the bracket 8.
What is necessary is just to hold | maintain in the position which contacted. But lock lever 3
The bracket 8 is required to have a structure that is always stretched by the spring 6 for convenience at the time of unlocking, which is one of the features of the present invention, and automatically returns to the release position when it is not held at the lock position. The lock box 12 is provided in the
To stop the rotation of the lock lever. . The lock projection 10 is loosely fitted by the guide plate 11 and is slidable back and forth, and is constantly pressed to the lock lever 3 side by a holding spring 13 in the lock box 12. When the bicycle is parked with the stand 2 fixed, the lock lever 3 is rotated clockwise in FIG.
The tip 16 of the lock projection 10 pressed by 3 is
Automatically projecting in the direction of the rotating shaft 4 when the
After the fitting, the lock lever 3 cannot be rotated counterclockwise and is fixed. When the bicycle is run again, the unlocking lever 14 installed inside the lock box 12 is rotated counterclockwise around the shaft 15 in the notch 19 in the notch 19 so that the lock protrusion 10 is moved into the lock box 12. When the lock lever 3 is retracted, the lock lever 3 stretched by the force of the spring 6 is disengaged from the distal end portion 16 of the lock projection 10 and automatically returns to the lock release position, and then the stand 2 can also return to the running position. The distal end portion 16 of the lock projection 10 has an appropriate curvature in the shape of the contact portion so that the outer surface 20 of the distal projection 9 can slide through easily. Similarly, the shape of the outer surface 20 of the distal end protruding portion 9 of the lock lever 3 is made concentric with the lever rotation shaft 4 or has a shape close to it in order to facilitate the rotational movement.

FIG. 2 is an exploded perspective view showing a part of the parts related to the lock projection 10. Unlocking lever 1 connected to lock body 25
Numeral 4 fits into the notch 19 and rotates around the shaft 15 to move the lock projection 10 back and forth. The lock itself is key 2
At 6 a rotation is given.

FIG. 3 shows a second embodiment in which the hole 21 of the lock lever 3 in FIG.

FIG. 4 shows a third embodiment. The stepped lock lever 22 has a structure in which a concave portion 24 is provided on the outer surface 20 of the distal end projection 9 of the lock lever. When the lock lever 22 is kicked in, the lock projection 10 retreats and then comes to the lock position. When the lock projection 22 comes to the lock position, the tip 16 projects into the recess 24 by the repulsive force of the spring 13 and the lock lever 22 is fixed. Release lever 14 to shaft 15
When the lever is rotated counterclockwise in the figure, the lock lever 22 is released and the vehicle can run. The shape of the outer side surface 20 has an appropriate curvature as in the example of FIG.

FIG. 5 is a perspective view of the stepped lock lever 22. As shown in FIG.

FIG. 6 shows a fourth embodiment. A rotary lock projection 23 having a structure different from that of the lock projection 10 used in the first and third embodiments is used. In this embodiment, when the stepped lock lever 22 used in the third embodiment is used and kicked in with a foot, the hook portion 28 of the rotary lock projection 23 is inserted into the recess 24 at the lock position.
5, and is pressed and fixed by a spring 13.
Rotary lock projection 2 interlocked with lock body 25 when running
When the lever 3 is rotated back about the shaft 15 in the counterclockwise direction in the figure, the stepped lock lever 22 is automatically disengaged by the action of the spring 6 and returns to the running position, so that the stand 2 can be raised and run.

FIG. 7 is an exploded perspective view of components around the rotary lock projection 23. FIG.

[0012]

According to the present invention, the bicycle user stands up with his foot when parking the bicycle, then simply kicks in the lock lever to automatically end the trip lock and immediately leave the bicycle. The work process is reduced by half, and bicycle parking work becomes very efficient. When you start running, you only need to unlock the lock lever and the lever return spring automatically returns it to the released position. Even a minute's worth of bicycle parking in the morning is important, and shortening the time is a huge benefit to users. In terms of price, there is little change since only a small modification of the conventional parts and a change in the position where the lock is attached, and the improvement of the function is added. Therefore, the value is substantially improved, and it is very economical.
