Description

[Detailed description of the invention] (Industrial application field) The present invention grasps a wire string body (hereinafter collectively referred to as wire) such as a wire, wire rope, cable, etc. and fixes it at a predetermined location in the longitudinal direction. The present invention relates to a hanging tool used for hanging articles, and specifically relates to a hanging tool having a roller chuck structure.

(Prior art) This type of hanging device is used, for example, when displaying various products and their display shelves by hanging them at appropriate points on wires suspended from the ceiling or other fixtures. It has the advantage of being able to be used for exhibitions, displays, etc., with a good appearance and an excellent interior design.

By the way, various types of conventional hanging devices of this kind have been proposed that adopt a ball chuck structure or a roller chuck structure, but the former has the disadvantage of having a weak chuck force. Regarding the roller chuck structure, Japanese Utility Model Publication No. 58-51470 and Utility Model Publication No. 56-
One having the structure shown in Publication No. 125550 and the like is known.

(Problems that the invention attempts to solve) However, the one in Utility Model Publication No. 58-51470,
The roller retainer inside the casing not only complicates the structure, but also increases the size of the casing itself. Furthermore, since a roller guide is provided in addition to the roller retainer, there is a drawback that the molding process of the casing becomes troublesome.

The device disclosed in Japanese Utility Model Application No. 56-125550 has the disadvantage that assembly is more complicated because the roller guide is composed of a freely moving cam. In any case, there was a problem that the number of parts was large and assembly was complicated.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to obtain a hanging tool that has a simple structure, a reduced number of parts, and can be made smaller and lighter overall.

(Means for Solving the Problems) In order to meet such demands, the hanging tool according to the present invention is a casing in which a pair of tapered surfaces facing each other are formed on both sides of the casing so as to converge at one end. A pair of rollers that are rotatably interposed in the space and hold the wire are urged toward the one end side, and a wedge-shaped roller whose upper end is substantially parallel to the tapered surface is inserted into the space from the other end opening of the casing. This is characterized in that a support member having a pair of roller support pieces is inserted and integrated.

(Operation of the invention) According to the invention, by simply inserting the roller and the support member from the other end opening of the casing and integrating them,
Assembled and manufactured.

In use, the rollers are appropriately and smoothly rolled between the inner surface of the casing and the roller support piece of the support member, without the use of a special cage or the like, and the required roller chuck function can be obtained.

(Embodiments of the invention) Hereinafter, the invention will be described in detail using embodiments shown in the drawings.

Figures 1 to 3 show an embodiment of the hanging device according to the present invention, and 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. The casing has a hanging hook 2 formed therein, and a pair of tapered surfaces 3, 3 are formed on both sides of the inner surface of the upper end side of the casing so as to face each other so as to converge toward the one end side. 4 is this casing 1
This support member has a flange portion 4a that is integrally assembled to the lower other end side and constitutes the suspension casing as a whole.As is clear from FIG. A pair of left and right roller support pieces 6, 6 formed in a wedge shape with tapered surfaces 5, 5 parallel to the pair of tapered surfaces 3, 3 are integrally formed, and these support pieces 6, 6 are formed integrally with each other. It 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. Reference numeral 10b is an operating portion of this locking member 10.

Reference numeral 11 denotes an unlocking member whose inner end 11a faces into the casing 1 through an opening 1a provided on the upper end side of the casing 1, facing the locking member 10, and is capable of pressing the rollers 7, 7 in the opening direction. 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 lock 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 of the wire 8 is unlocked. It is something that will be done.

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,
The number of parts was significantly reduced.

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.

The lock member 10 can prevent a fall accident due to accidental release of the lock.

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 the wire cord body is 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 the invention) As explained above, according to the hanging tool of the invention, the roller chuck function is achieved by rolling the roller between the inner surface of the casing and the tapered surface of the roller support piece without using a special retainer or the like. The overall structure was simple and the number of parts could be reduced.

Moreover, it is excellent in terms of moldability and assemblability,
It has great practical effects, such as cost reduction and overall miniaturization and weight reduction.
