Description

[Detailed description of the invention] [Industrial field of application] The present invention is a method for grasping a wire body (hereinafter collectively referred to as wire) such as a wire, wire rope, cable, etc. and fixing it at a predetermined location in the longitudinal direction. The present invention relates to a hanging tool used for hanging articles, and more particularly to a locking mechanism for maintaining the hanging position of the hanging tool.

[Conventional technology]

This type of hanging device is used, for example, when displaying various products and their display shelves by hanging them on appropriate points on wires suspended from the ceiling or other fixtures, etc., and is aesthetically pleasing. This exhibits the advantage of being able to perform exhibits and displays that are excellent in terms of interior design and the like.

By the way, in this type of conventional hanging device, the chuck may be released by contacting the chuck from the opposite direction, and an accident may occur in which the hanging device falls. Therefore, although it has a ball chuck structure, a lock member shown in Japanese Utility Model Application Publication No. 58-73162 has been proposed.

[Problem that the invention attempts to solve]

However, the above-mentioned locking member has a structure exclusively for ball chucks, and is attached to the upper part of the hanging portion. Therefore, if the hanging equipment is located higher than your height, you will have to raise your hand to lock the equipment after horizontally adjusting each hanging equipment, which is not very efficient. It was hot. Further, in the above case, the locking member cannot actually be released because it is obstructed by the hanging panel, etc., and there is a drawback that the hanging panel must be removed to perform the work.

The present invention has been developed in view of the above-mentioned circumstances, and its object is to provide a hanging device that allows the chuck position to be easily locked and unlocked.

[Means for solving problems]

In order to meet such demands, the hanging device according to the present invention is rotatably installed in a casing space in which a pair of opposing tapered surfaces are formed on both inner surfaces so as to converge at one upper end. A pair of rolling elements gripping the wire are urged toward the one end side, and the rolling elements are rolled in a convergent direction along the tapered surface to narrow the gap and change the gripping state of the wire. A locking member for locking the rolling element is screwed in from the outside and provided below the casing, and an unlocking member for pressing the rolling element in the opening direction when the rolling element is unlocked by the locking member is provided above the casing. It is characterized by being equipped with.

[Effect of invention]

According to the present invention, by rotating the locking member from below the casing located below the hanging panel, the rolling elements are rolled along the tapered surface of the casing, thereby narrowing the interval. As a result, the wire is gripped by the rolling elements and the position of the chuck relative to the wire is determined.

When the lock member is reversely rotated from below the casing in the chuck state, the locking of the rolling elements is released. When the unlocking member is pushed in from above the casing with the rolling element in the unlocked state, the rolling element is rolled downward and the gripped state is released.

[Example of idea]

Hereinafter, the present invention will be explained in detail using embodiments shown in the drawings.

Figures 1 to 3 show an embodiment of the hanging device according to the present invention. In these figures, the reference numeral 1 has a substantially rectangular tube shape as a whole, and a part of the outer wall of the hanging device has an object. A casing in which a hanging hook 2 is formed, and on both sides of the inner wall surface of the upper end,
A pair of tapered surfaces 3, 3 are formed facing each other so as to converge toward one end. Reference numeral 4 denotes a support member having a flange portion 4a that is integrally assembled on the other lower end side of the casing 1 and constitutes the suspender casing as a whole. , a pair of left and right roller support pieces 6, 6 are integrally formed, the tips of which are wedge-shaped with tapered surfaces 5, 5 parallel to the pair of tapered surfaces 3, 3, and these support pieces 6,6
is configured to be inserted into the casing 1 along both side wall surfaces thereof. Here, the casing 1 and the flange portion 4a of the support member 4 are integrated by caulking, adhesion, or the like.

7, 7 are a pair of rollers that grip the wire 8;
As is clear from FIG. 2, these rollers 7, 7 are arranged in a space formed between the tapered surfaces 3, 3 of the casing 1 and the tapered surfaces 5, 5 on the side of the supporting pieces 6, 6 facing thereto. It is interposed in such a way that it can freely roll with both ends supported. Each of these rollers 7, 7 is biased by a spring 9 disposed between the support pieces 6, 6 in the direction in which the tapered surfaces converge (upward in the figure). This spring 9 is activated by the rollers 7 and 7 when the roller chuck state is released by an unlocking member to be described later.
It plays the role of restoring.

10 is screwed into the screw hole 4b of the support member 4 from the outside to cause the rollers 7, 7 to roll along the tapered surfaces 3, 3, 5, 5 in the direction of convergence between the rollers 7, 7. This is a locking member that narrows the gap, and the inner end of its threaded shaft portion 10a is screwed into the casing 1 to a position where the rollers 7, 7 are locked. 10b is an operating section of this locking member 10.

Reference numeral 11 denotes an unlocking member whose inner end 11a can press the rollers 7, 7 in the opening direction when viewed from inside the casing 1 through an opening 1a provided on the upper end side of the casing 1 facing the locking member 10. The unlocking member 11 can unlock the wire 8 from being held by the rollers 7 by being pressed inward from the outside when the locked state by the locking member 10 is released. It is.

In the figure, reference numeral 12 denotes a cap made of an elastic material such as rubber and covering the support member 4 integrally provided at the lower end of the casing 1.

According to the hanging tool having the above-described configuration, the wire 8 is inserted through the shaft hole 13 bored in the upper unlocking member 11, and is inserted downward through the shaft hole 14 on the lower locking member 10 side. By pulling out
It is attached to the wire 8, and in this state, the rollers 7, 7 sequentially roll upward in the space between the tapered surfaces 3, 3, 5, 5 according to the diameter of the wire 8. It is possible to obtain a roller chuck state in which the object is gripped from both sides. Therefore, if the locking member 10 is screwed in in this state and the rolling state of each roller 7 is locked at its inner end, the hanging tool will be locked in the middle of the wire 8. This will result in a locked state.

On the other hand, in order to unlock this, the lock member 1
0 and then press the upper unlocking member 11, the rollers 7, 7 are rolled downward in the space formed by the tapered surfaces 3, 3, 5, 5, and the grip state with the wire 8 is released. It is something that

According to the above embodiment, the following effects are achieved.

The hanging tool can be configured from a minimum of a casing 1, a pair of rollers 7, 7, a support member 4 having roller support pieces 6, 6, and a spring 9,
We were able to significantly reduce the number of parts.

By forming the roller support pieces 6, 6 of the support member 4 into a wedge shape, the rollers 7, 7 can be rolled with the casing tapered surfaces 5, 5 without using a conventional cage or the like. I was able to hold it.

Note that the present invention is not limited to the structure of the embodiment described above, and the shape and structure of each part may be modified and changed as necessary. For example, wire 8
As long as it is a wire-shaped body made of a single material or multiple materials, it is sufficient that the cross-sectional shape is not limited to a circle but may also be an ellipse or various polygonal shapes. be understood.

[Effect of idea]

As explained above, according to the hanging tool of the present invention, the locking member 10 can prevent falling accidents due to erroneous unlocking, and also facilitates locking and unlocking operations from below the casing. be able to.
