Abstract

PURPOSE:To prevent a shackle from being cut off by bringing wall sections covering both sides of the shackle near to the shackle, and integrally forming the wall sections from the upper ends of both sides of a main body section. CONSTITUTION:In a cylinder lock 1, an inverted U-shaped shackle 3 is projected upwards from a main body section 2, and wall sections 5 and 6 covering both ends of the shackle 3 are formed integrally from the upper ends of both sides of the main body section 2 so as to be brought near to the shackle 3. The height of these wall sections 5 and 6 is formed in approximately the same height as the upper end of the shackle 3 under a locked state. The shackle 3 of such a cylinder lock 1 is engaged with annular fittings 9 under the state, in which a door 8 is closed and the annular fittings 9 are inserted into the hole 7a of fittings 7 with the hole. The wall sections 5 and 6 are formed so as to be brought near to the shackle 3 and the annular fittings 9 cannot be moved at the places of the wall sections 5 and 6 at that time, and the shackle 3 is difficult to be gripped by the front end of a wire clipper, etc., thus the shackle 3 is hard to cut.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock having an inverted U-shaped vine such as a cylinder lock or a code lock.

[0002]

2. Description of the Related Art Conventionally, various locks having inverted U-shaped vines such as cylinder locks and code locks have been known, but the vines are projected upward from the main body of the lock and exposed to the outside. However, there is a problem that the vine is cut and broken by a wire clipper or the like in a use state.

[0003]

SUMMARY OF THE INVENTION The present invention is intended to solve such a problem, and an object thereof is to provide a lock which is difficult to cut and is not broken even if the temple is to be cut with a wire clipper or the like. is there.

[0004]

In order to solve this problem, the present invention is a lock comprising an inverted U-shaped vine so as to project upward from the lock main body, and both sides of the main body are provided. The gist of the invention is that a wall portion covering both sides of the temple from the upper end is integrally provided so as to be close to the temple.

[0005]

[Effect] With this configuration, even if the vine is to be cut with a wire clipper or the like, the walls covering both sides of the vine from the upper ends of both sides of the main body are integrally provided so as to be close to the vine, which makes it difficult to cut and breaks. It is possible to provide a lock that is difficult to be controlled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 3, reference numeral 1 is a cylinder lock as an example of a padlock, and an inverted U-shaped temple 3 projects upward from a main body 2. Reference numeral 4 is a keyhole at the lower end of the main body 2.

In such a cylinder lock 1, in the embodiment of the present invention, wall portions 5 and 6 covering both sides of the temple 3 from the upper ends of both sides of the body portion 2 are integrally provided so as to be close to the temple 3. . Specifically, the wall portion 5 that covers one side portion of the temple 3 that is the rotation support shaft side when the lock is released has a substantially U-shaped planar shape, and the wall portion 5 that covers the other side portion of the temple 3 is formed. The plane shape of the portion 6 is substantially L-shaped. Further, the heights of the wall portions 5 and 6 are configured to be substantially the same as the upper end of the temple 3 in the locked state.

FIG. 3 shows a usage state of the cylinder lock 1 having the above structure. In FIG. 3, 7 is a metal fitting with a hole attached to the door 8 side, 9 is a hole 7 of a metal fitting 7 with a hole on the door 8 side when the door 8 is closed and attached to the vertical frame 10 at the doorway.
It is an annular metal fitting that fits in a.
Closes the door 8 and attaches the annular metal fitting 9 to the hole 7a of the metal fitting 7 with a hole.
It is locked to the annular metal fitting 9 in a state of being fitted into.

As is apparent from FIG. 3, the annular metal fitting 9 is locked to the temple 3 at a position between the walls 5 and 6 which cover both sides of the temple 3, and as described above, the walls 5 and 6 are formed. Since the ring-shaped metal fitting 9 is provided so as to be close to the temple 3,
At position 6, it cannot move.

As described above, since the annular metal fitting 9 is locked to the temple 3 at the position between the walls 5 and 6, it is difficult to grip the temple 3 with the tip of the wire clipper, and the temple 3 is cut. Hard to do.

In the embodiment shown in the drawings, the cylinder lock 1 is taken as an example, but any lock other than the cylinder lock, such as a code lock, having an inverted U-shaped vine can be used.

[0012]

As described above, according to the present invention, even if the vine is to be cut with a wire clipper or the like, the wall portions covering both sides of the vine from the upper ends of both sides of the main body are integrally provided so as to be close to the vine. Therefore, it is possible to provide a lock that is difficult to cut and is not easily broken.
