Description

[Detailed explanation of the invention] [Industrial field of application] For example, in parking lots, etc., cables such as chains or ropes are hung over the entrances at night to prevent outsiders from entering. It is designed to be prevented.

This invention relates to a locking fitting for locking the end of such a cable body.

[Conventional technology]

An example of a locking fitting for a cable body that has been commonly used in the past is one in which a hook-shaped fitting is welded to a column.

In this case, a locking ring connected to the end of the cable body is engaged with the metal fitting.

Another conventional example of a locking metal fitting is one in which an annular metal fitting is welded to a column. In this case, the end of the chain is inserted through the metal fitting, wound, and the wound end is connected with a lock.

[Problem that the invention attempts to solve]

However, in the former case, the locking ring can be easily removed from the metal fitting, so the crime prevention function cannot be fully demonstrated.

In the latter case, it is necessary to lock and unlock the lock when locking the chain to the metal fitting and when removing the chain from the metal fitting, which requires troublesome work. Furthermore, there was a risk that the lock key would be lost and it would be impossible to remove the chain.

The present invention was made in order to eliminate the drawbacks of the conventional example, and an object of the present invention is to provide a locking fitting for a cable member that can be quickly and reliably connected to a cable member.

[Means for solving problems]

As shown in FIG.
extend oppositely to the front surface of the substrate 1 such that the tip of the spring member 9 is located on the outer side of the circumferential edge 7 near the open end 6 of the locking part 5, and the tip of the spring member 9 and the circumferential edge 7 is provided with a gap g that allows the locking ring 12 connected to the end of the cable body 11 to enter in a wedge shape.

Here, the gap g only needs to be a value that allows the locking ring 12 to substantially penetrate in a wedge shape, that is, a value smaller than the thickness dimension D of the locking ring 12. For example, if the gap g is set to zero, the spring member 9 An embodiment may be adopted in which the tip portion is brought into contact with the peripheral edge portion 7.

[Effect]

In the above configuration, when the locking ring 12 is inserted into the gap g in a wedge shape as shown in FIG. Since it is firmly engaged with the portion 8, there is no risk of it coming off unexpectedly.

[Embodiment 1] FIGS. 1 and 2 show a first embodiment of a locking fitting according to the present invention.

The locking fitting is a spring member 9 on the front of the square board 1.
The locking fitting body 4 and the locking fitting main body 4 are configured to extend vertically to face each other. Board 1 has bolts 2 fastened at the four corners
It is fixed to the pillar 3 in an almost vertical position. The extending base end of the locking fitting main body 4 is welded to the center of the lower part of the substrate 1. The locking fitting main body 4 has a C-shaped locking portion 5 at the extending end thereof. The open end 6 of the locking portion 5 is located on the proximal end side.

The spring member 9 is, for example, a metal wire bent into a U-shape.
10 terminals are welded to the substrate 1. Spring member 9
The length is set slightly shorter than that of the locking fitting main body 4, and the length between the tip of the spring member 9 and the locking part 5, more specifically, the upper peripheral edge 7 close to the release end 6. A gap g is provided between them. This gap g is smaller than the thickness D of the locking ring 12 connected to one end of the cable body, that is, the chain 11.

Therefore, with the locking ring 12 in a horizontal position, the gap g
When inserted into the wedge shape, the locking ring 12 is inserted as described above.
is engaged with the inner deep part 8 of the locking part 5. On the other hand, if the locking ring 12 in the engaged state is pushed out horizontally toward the substrate 1 side, and in this state, the locking ring 12 is lifted up and brought into contact with the lower surface of the spring member 9, and the chain 11 is pulled forward. The locking ring 12 is designed to be detachable from the locking portion 5.

The tip of the spring member 9 is rounded to prevent the spring member 9 and the locking ring 12 from being damaged during engagement and disengagement operations.

[Embodiment 2] FIG. 3 shows a second embodiment of the present invention. In this case, the tip of the spring member 9 is tilted downward to substantially reduce the gap g. Therefore, there is an advantage that the locking ring 12 can be more reliably prevented from coming off from the locking portion 5.

In the illustrated example, the tip of the spring member 9 is located at the peripheral edge 7.
Although it is approximately at the same height as this, it may also be positioned below this.

[Embodiment 3] FIG. 4 shows a third embodiment of the present invention. In this case, the manner in which the spring member 9 is attached to the substrate 1 is different from that of the second and third embodiments. That is, the base end side of the spring member 9 is inserted into the board 1, and the insertion end 9a is bent downward to be attached to the board 1.

[Embodiment 4] FIG. 5 shows a fourth embodiment of the present invention. In this case, the cross-sectional shape of the spring member 9 is V-shaped. According to this embodiment, the locking ring 12 is
When the locking ring 12 and the spring member 9 are inserted into the housing, the locking ring 12 and the spring member 9 come into line contact, which has the advantage that the frictional force is small and the engagement operation is easy to perform.

[Embodiment 5] FIG. 6 shows a fifth embodiment of the present invention. In this case, a hook 14 that engages with the pipe 13 is attached to, for example, the back side of the base plate 1, and the locking metal fitting is movable in the front and back direction, and the cable members 1 of different lengths are attached.
It has the advantage that it can also be applied to 1.

[Modified example]

The entire details of the illustrated embodiment are as described above,
The present invention can be modified in various ways. That is,
In each of the above embodiments, the gap g may not be provided, and the tip of the spring member 9 and the peripheral edge 7 of the locking part 5 may be in contact with each other, or the spring member 9 and the locking fitting body 4 may be placed vertically. They may also extend in opposite directions, for example in the horizontal direction.

[Effect of idea]

In the case of the present invention as described above, the locking fitting main body 4 having the C-shaped locking part 5 at the tip and the spring member 9 are extended on the substrate in a facing manner, and the peripheral part near the open end of the locking part 5 is The locking ring 12 connected to the end of the cable body 11 is inserted in a wedge shape between the portion 7 and the extending end of the spring member 9, so that the locking ring 12 can be simply pushed in. This can be reliably engaged with the locking portion 5. Therefore, unlike the first conventional example described above, the crime prevention function can be effectively exhibited. Further, unlike the second conventional example, there is an advantage that a lock or the like is not required and engagement and disengagement operations can be performed quickly.

Furthermore, when adopting a configuration in which the locking fitting is made movable as in the fifth embodiment, there is an advantage that it can be applied to cables 11 having different lengths.
