Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wire lock for locking an object to be locked, such as a bicycle wheel, by passing a wire therethrough.

[Prior Art] Wire locks, which are generally used to lock objects such as bicycles, incorporate a lock such as a code lock into the body and pass a wire through the object.
It has been widely used in place of the conventional bolt lock that is attached to the seat post of a bicycle and inserted into the rib of the wheel.

With conventional bolt locks, if the mounting position is changed, for example, when the bolt is rotated along the outer circumference of the seat post, the bolt comes out of the rib and is no longer useful for locking, losing its anti-theft effect. On the other hand, wire locks suitably secure the seat post and wheel of a bicycle, for example, with a wire, and therefore do not impair the effectiveness of preventing theft of the object to be locked, such as a bicycle. However, even with such a wire lock, the following problems remain.

When unlocking a wire lock used for a locked object, the user must store the wire lock separately from the locked object or store it in a storage box for the locked object, and the wire lock itself may be lost or stolen. I'm awake. For this reason, if you wrap a wire around the object to be locked, such as the frame of a bicycle, and store this wire lock when unlocking, you can prevent loss or theft of the wire lock, but it is said that the object to be locked is locked. You have to do unnecessary wire winding and locking work that is unrelated to the original work. Furthermore, if the wire is not wrapped and handled carefully, the wire may become wrapped around the wheel while riding the bicycle, which is extremely dangerous.

From this point of view, the microfilm photographing the contents of the specification and drawings attached to the application of Utility Model Application No. 54-66746 discloses a wire lock that is fixed to a bicycle frame pipe or the like using a mounting member. . According to this method, the wire lock can be fixed to the locked object even when the lock is unlocked, thereby preventing loss or theft.

[Problems to be solved by the invention] However, with the above-mentioned wire lock mounting member,
Since the attachment member itself simply connected the object to be locked and the lock body without any ingenuity, there was a constriction in the space between them, which could easily break due to the impact that often occurs on bicycles, etc. It was easily twisted. This has caused problems in terms of durability. Moreover, with this wire lock, the wire was gradually taken out from one end and wound around the lock body due to the rigidity of the wire itself and the use of rollers, so the work was slow. For this reason, installation and storage took time and were inconvenient. Therefore, it is necessary for any wire lock to be easy to store without fear of loss or theft, have sufficient strength or durability, and be able to be installed and stored quickly. There was nothing that had the same performance.

Therefore, the present invention solves the above problems and provides a wire lock that is easy to store without fear of loss or theft, has sufficient strength or durability, and can be quickly installed and stored. The purpose is to

Structure of the invention [Means for solving the problems] In order to solve the above problems, the means used in the invention are as follows: A lock body provided with a lock into which a lock rod is inserted and locked; A wire lock consisting of a wire having one end fixed and the lock lever attached to the other end, the wire being passed through an object to be locked to lock the lock, comprising: a cylindrical lock body; and one end of the lock body. a recess that is formed in a recess that fits into a predetermined position of the object to be locked; a body attachment member that fixes the lock body to a predetermined position of the object to be locked; a wire attached to the outer periphery of the lock body so that the wire can be pulled out; The gist of the present invention is a wire lock characterized by comprising: a wire storage means that stores the wire by automatically winding it using its own contraction force.

[Function] According to the wire lock of the present invention, the main body attachment member fixes the lock main body to a predetermined position of the object to be locked, for example, to the seat post of a bicycle. At this time, the wire lock of the present invention has a concave portion that fits into a predetermined position of the object to be locked, so it is fixed firmly and compactly, and therefore, it cannot be twisted by impact or the like.
Prevents threading. Therefore, it has good durability.

In addition, the wire storage means of the wire lock of the present invention is
It has a simple structure in which the wire is automatically wound around the outer circumference of the lock body using the contraction force of the wire itself.The entire wire can be taken out and wound at once, so it is gradually removed from the inside of the lock body. Compared to the case where the wire is taken out and wound from one end, it can be installed and stored more quickly. Therefore, it is very convenient for users. Moreover, according to the wire lock of the present invention, since the wire is wound around the outer periphery of the lock body, its diameter increases as a whole, and the moment applied to the lock body due to removal and winding increases. By providing the recessed portion in the lock body, the strength is increased so as to be able to cope with the above-mentioned large moment, so the lock is hard to break and has good durability.

[Example] Next, an example using the present invention will be described based on the drawings.

FIG. 1 is a front view including a partial cross section of a wire lock 1 according to this embodiment, and FIG. 2 is a sectional view taken along line II in FIG. 1.

The cylindrical lock main body 2 has a recess 2a on the bottom surface that conforms to the shape of an object to be locked, such as a seat post P of a bicycle, and a well-known lock insertion lock 3, which will be described later, on the top surface. On the bottom surface of the lock body 2, via the seat post P, there is a mounting bracket 4 equipped with a U-shaped curved part 4a that matches the shape of the seat post P, and mounting pieces 4b provided on both sides of the opening. It is attached by screwing two screws 4c into screw holes provided on the bottom surface of the lock body 2. In this way, the wire lock 1 is fixed to the seat post P of the bicycle. The lock insertion lock 3 includes a lock insertion hole 3a made in the lock body 2, a lock stopper 3b, and a lock returner 3.
c. When the lock rod 5, which is composed of an unlocking key 3d and a spring and has a locking disk 5a at the tip, is inserted, the lock rod stopper 3b is inserted into the disk 5a of the lock rod 5, as shown in FIG. The locking rod 5 is prevented from coming out from the locking rod insertion hole 3a for locking. After locking, the unlocking key 3d can be removed from the lock body 2. When the unlocking key 3d is moved in the direction of the arrow in the figure around the fulcrum 3e, the lock rod stopper 3b is released and the lock rod 5 is moved by the lock returner 3c under the action of a spring. The lever insertion lock 3 is unlocked by being pushed back toward the entrance of the lock insertion hole 3a.

One end of a coil wire 6 having a stretchable coil shape and whose outer periphery is coated with synthetic resin is fitted and fixed on the outer periphery of the bottom side of the lock body 2.
The above-mentioned lock lever 5 is fixed to the other end. When the lock is unlocked, the coil wire 6 is housed around the outer periphery of the lock body 2 in a contracted state as shown in FIG. 1 (the coil wire 6 wound around the lock body 2 is shown by a dashed line in the figure).

When locking the wire lock 1, the coil wire 6 is pulled out from the outer periphery of the lock body 2 and hung between the seat post and the wheel of the bicycle.
After that, the lock 5 fixed to one end of the coil wire 6 is inserted into the lock insertion lock 3a of the lock insertion lock 3,
As mentioned above, the lock rod 5 is fixed, and the lock rod inserts the lock 3.
The lock is completed. On the other hand, when the lock rod 5 is released by the unlocking key 3d, the lock rod insertion lock 3 of the wire lock 1
is unlocked as mentioned above. When the user releases the above-mentioned hanging of the coil wire 6, the coil wire 6 automatically moves to the lock main body by its own contraction force.
It fits around the outer circumference in a contracted state.

As explained above, the wire lock 1 of this embodiment
Since the wire lock is fixed to the object to be locked, there is no need to worry about the wire lock itself being lost or stolen, and the coil wire automatically fits around the outer periphery of the lock body by its own contraction force, making it easy to store. Moreover, at this time, the wire lock 1 of the present invention is fixed firmly and compactly because the recess 2a that matches the shape of the bicycle seat post P is formed.
It prevents it from being broken due to impact, etc., and from being twisted or threaded. Therefore, it has good durability. In addition, since the entire coil wire 6 can be taken out and wound at once,
Compared to the case where the lock body 2 is gradually taken out and wound from one end from inside the lock body 2, it can be installed and stored extremely quickly. Therefore, it is very convenient for users. Furthermore, according to the wire lock 1 of the present invention, since the coil wire 6 is wound around the outer periphery of the lock body 2, its diameter increases as a whole, and the moment applied to the lock body 2 due to removal and winding increases. By providing the concave portion 2a in the lock body 2 as described above, the strength is increased so as to be able to cope with the above-mentioned large moment, so that the lock is hard to break and has good durability. Since the coil wire is coated with synthetic resin, it is safe to handle. In addition, since the number of component parts is small and the shape is simple, the manufacturing cost of this wire lock 1 is extremely low.

The present invention is not limited to the above embodiments, and may be implemented in any manner without departing from the gist thereof.

Effects of the invention The wire lock according to the invention described in detail including the examples above is easy to store without fear of loss or theft.
This wire lock has sufficient strength, that is, durability, and can be quickly installed and stored.
