Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bicycle wire lock that can be attached to a seat post portion of a bicycle, and more particularly, a sports-type bicycle that has no room for attaching a lock such as a horseshoe-shaped ring lock to a fork. This bicycle is characterized in that it can be easily locked before being locked and can be easily carried when not in use.
[0002]
[Prior art]
An example of a bicycle wire lock in which the wire lock is held by a holder attached to a bicycle seat post is disclosed in Japanese Utility Model Application Laid-Open No. 7-19077.
[0003]
[Problems to be solved by the invention]
The wire lock of the above-mentioned prior application is that the holder attached to the seat post and the wire lock are separate, and it takes time to attach the belt-like fixture connected to the holder around the seat post and screw it, Since the wire part of the lock is a long spiral, it is difficult to attach and detach to the tire during locking and unlocking, and the free end of the unlocked wire part is inserted into the insertion hole provided in the holder. Since the lock was locked on the lock body, there were inconveniences in use, such as a troublesome holding operation to the holder when not in use.
[0004]
On the other hand, for example, a bicycle lock such as a horseshoe-shaped ring lock is easy to unlock and lock if attached, but it is not attached to a sports type bicycle that has no room for attachment to a fork that sandwiches a tire. There is a drawback that it is difficult.
For this reason, there is no inconvenience in mounting like a conventional holder, and it is easy to unlock and lock like a horseshoe-shaped ring lock, and it is convenient for carrying when not in use. Developing has become a problem to be solved.
[0005]
[Means for Solving the Problems]
Accordingly, the present invention provides a cylinder lock mechanism as a lock mechanism that fixes a short flexible wire portion having a length to be inserted horizontally through a tire portion of a bicycle, and one end of the wire portion and locks the other end of the wire portion. A lock body provided, and the other end of the wire part so that the other end can be opened, and the lock body is fixed to one end, and the other end is attached with a clamp lever shaft for fixing a bicycle seatpost; Provided is a bicycle wire lock in which a keyhole is provided on an end surface, and a bifurcated bracket integrally extended with an inner cylinder portion of the cylinder lock mechanism in which the other end of the wire portion is hinged .
[0006]
The wire lock of the present invention can be easily attached to the desired bicycle by inserting the shaft hole of the mounting tool into the shaft lever of the seat post provided on a normal bicycle and tightening it together with the clamp of the seat post. And does not require a special mounting position.
In addition, since the fixture and the lock body are joined together, it is easier to handle compared to separate ones, and the operation of locking and unlocking can be done as easily as a normal wire lock. Since the wire part is short, it can be easily inserted into and removed from the tire.
[0007]
When the wire lock of the present invention is not in use, it can be carried around without difficulty in traveling the bicycle by locking the wire part unlocked from the lock body in the standing pipe, and its operation can be simplified and convenient. is there.
The present invention solves the above problems as described above.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
As shown in FIG. 1, a wire lock illustrated as an example of the most preferred embodiment of the present invention includes a fixture 1 supported by a shaft c of a clamp lever C of a seat post P of a bicycle S, and an integral with the fixture 1. The lock body 2 and one end of the lock body 2 are fixed to the lock body 2, and the other end of the lock body 2 is locked to the body 2.
[0009]
The lock body 2 is integrally fixed to the tip of the fixture 1, and a known cylinder lock mechanism that is not shown in detail is used as a lock mechanism that locks the other end of the wire portion 3. The other end of the wire portion 3 that is attached to and detached from the lock body 2 by being locked and unlocked is hinged to a bifurcated bracket 6 that is integrally extended from the inner cylinder portion 5 of the cylinder lock mechanism having a key hole 4 on the end surface. ing.
[0010]
【Example】
Examples of the present invention will be described below.
As shown in the figure, the fixture 1 has a box-shaped main body portion 9 extending from a pair of left and right mounting portions 8 each provided with a shaft hole 7 through which the shaft c of the clamp lever C is inserted. A cylindrical lock body 2 from the outer periphery between the other half-circular cross-sectional sandwiching portion (not shown) that is provided along the back surface of the sandwiching portion 10. The lock body 2 is rotatably held by clamping and holding both clamping parts together with a hook 11.
[0011]
The lock body 2 has a bifurcated bracket 13 having a fixed end of the wire portion 3 hinged between the folded portion 12 formed on the end surfaces of the both sandwiched portions and the both sandwiched portions secured by the hooks 11. By doing so, the other end of the wire portion 3 is left open so as to be prevented from coming off in the axial direction.
[0012]
As shown in the drawing, the wire portion 3 connected to the lock body 2 via the bifurcated brackets 6 and 13 as described above is relatively large enough to be inserted through the tire T and bend in a U shape. Therefore, insertion and escape of the tire T can be easily and smoothly performed during locking and unlocking.
[0013]
The wire lock having the above-described configuration is constructed by inserting the key 14 into the key hole 4 from the state where the wire portion 3 is locked through the tire T as shown in FIG. 1 and the inner cylinder portion 5 of the cylinder lock mechanism. 2, and unlocked as shown in FIG. 3, and then the wire portion 3 is hidden and locked in the standing pipe 15 so as to be held on the vehicle body below the seat post P of the bicycle S. , You can carry it without any obstacles.
[0014]
Moreover, since this wire lock uses the axis | shaft c of the clamp lever C of the seat post P of the bicycle S provided normally, it attaches the fixture 1 integrally provided with the lock main body 2, A band-shaped special attachment member is not required, and it can be easily attached to a bicycle having no attachment place where a ring lock can be attached.
[0015]
The structure of the locking mechanism employed in the wire lock of the present invention and the end portion of the wire portion to be locked is not limited to the embodiment, but has an appropriate structure according to the gist of the present invention. Needless to say, it is sufficient that the other end of the wire portion is locked and unlocked while leaving the fixed end on the main body side.
[0016]
【The invention's effect】
As described above, the wire lock of the present invention can be easily attached to the shaft of the clamp lever of the seat post provided in a normal bicycle, and does not require any special attachment position.
In addition, since the fixture and the lock body are integrally joined, it is easier to handle than the separate ones, and the operation of locking and unlocking can be done as easily as a normal wire lock, Since the wire part is short, it can be easily inserted into and removed from the tire.
[0017]
Furthermore, when the wire lock of the present invention is not in use, it is possible to carry the bicycle without hindrance to the bicycle by locking the wire portion in the standing pipe, and the operation can be simplified and convenient.
The present invention has extremely excellent effects as described above.
