Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for connecting a tubular member to a rope body.

[0002]

[Prior Art and Problems to be Solved]

 In order to easily divide a space mainly indoors, a guide rope is suspended between a plurality of movable support pillars.

At the end of this guide rope, by attaching a metal part having a bottomed cylindrical shape in which a hook is provided to the outside of the bottom, it is possible to attach / detach to / from a latching ring provided on the upper part of the movable column. Makes it easy. However, the process of connecting a metal bottomed cylindrical part and a rope, which is a textile product, has heretofore been a method of using a filling adhesive, which is not so easy and is easier and more reliable. A connecting structure that can be connected has been required.

The present invention has been made in view of the above problems existing in the prior art, and an object of the present invention is to easily and surely connect a tubular member to an end portion of a rope body. It is an object of the present invention to provide a structure for connecting a tubular member to a rope body that can be pulled.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the connecting structure of the tubular member to the rope body of the present invention comprises a rope body, a leaf spring member having a substantially U-shaped cross section, and a piercing member. With the axis of the spring-like member and the axis of the rope body substantially aligned, the end of the rope body is inserted into the leaf spring-like member, and the leaf spring-like member and the rope body are pierced by the piercing member. They are inserted into the tubular member in the closed state, and at the back side of the inward protrusion provided in the tubular member, at least both ends of the leaf spring member are at least pushed by the elastic force from the inward protrusion. Also, the tubular member is connected to the end of the rope body by expanding to the outside.

[0006]

[Action]

 The state in which the axis of the leaf spring-shaped member and the axis of the rope body are substantially aligned, the end of the rope body is inserted into the leaf spring-shaped member, and the leaf spring-shaped member and the rope body are pierced by the piercing member. Then, the leaf spring member, the rope body, and the piercing member are integrally inserted into the tubular member.

Then, at the inner side of the inward protrusion provided in the tubular member, both ends of the leaf spring member expand at least outward from the inward protrusion due to the elastic force. When the leaf spring-shaped member is inserted into the tubular member, the end portion of the leaf spring-shaped member elastically bends inward, and the end portion of the leaf spring-shaped member is located at the inner side of the inward projection. In the state where the end of the leaf spring is expanded to the outside of the inward projection, the end is urged outward, so the leaf spring member and the end of the rope body that is integral with it are pulled back from the tubular member. This is prevented, and the connection between the end of the rope body and the tubular member is maintained.

【Example】

 Embodiments of the present invention will be described with reference to the drawings. The drawings relate to a guide rope as one embodiment of the present invention, in which FIG. 1 is a sectional view of a main part and FIG. 2 is an assembly view of the main part.

The end portion 10 a of the synthetic fiber rope 10 is once heated and then cooled to be solidified into a mass, and then the vinyl tape 12 is wound.

A hook 16 is provided outward on a bottom portion 14a of a cylindrical member 14 having a bottomed cylindrical shape made of metal. An annular cutout 14c is formed on the inner peripheral portion of the opening of the peripheral wall 14b of the tubular member 14 so as to gradually increase in diameter toward the opening. The annular cutout 14c has a circular inner end at the lower end thereof. The protruding portion 14d is formed. In this embodiment, the inner diameter of the inward projection 14d is almost the same as the inner diameter of the tubular member 14 above the annular notch 14c, but any inner diameter may be larger or smaller. May be.

In the metal plate spring-like member 18, both side plates 18a and the bottom plate 18b are orthogonally connected to each other, and both end portions 18a1, that is, the lower end portions of the both side plates 18a in FIG. 1 are expanded slightly outward. It has an open U-shaped cross section. The leaf spring-shaped member 18 is formed so that both ends 18a1 generate an outward expanding elastic force in a state of being inserted into the tubular member 14 with its axis aligned with that of the tubular member 14.

With the axis of the leaf spring-like member 18 and the axis of the rope 10 substantially aligned with each other, the end portion 10 a of the rope 10 is fitted into the leaf spring-like member 18, and both sides of the leaf spring-like member 18 are inserted. The leaf spring member 18 and the end portion 10a of the rope 10 are pierced by the metal pin 20 (piercing member) through the piercing hole 18a2 provided in the plate 18a.

In that state, when the leaf spring member 18, the rope 10 and the pin 20 are integrally inserted into the tubular member 14, both end portions 18a1 of the leaf spring member 18 are inserted into the tubular member 14. An outwardly expanding elastic force is generated, and the annular notch 14c on the inner side of the inward protrusion 14d provided in the tubular member 14 has at least the inner ends 18a1 of the leaf spring-like member 18 at least. It spreads outward from the side projection 14d.

When the leaf spring-shaped member 18 is inserted into the tubular member 14, both end portions 18 a 1 of the leaf spring-shaped member 18 are elastically bent inward, and both ends of the leaf spring-shaped member 18 are bent. In a state where the portion 18a1 reaches the inner side of the inward projection 14d and spreads outward from the inward projection 14d, both end portions 18a1 thereof are urged outward, so that the leaf spring-like member 18 and The end portion 10a of the rope 10 that is integral with the end portion 10a is prevented from being pulled back from the tubular member 14, and the connection between the end portion 10a of the rope 10 and the tubular member 14 is maintained.

Unless stated otherwise, the dimensions, the number, the material, the shape, and the relative arrangement of the constituent parts in the description of the above embodiments are limited to only those parts. It is not intended to be limited to the above and is merely an example of description.

[0016]

[Effect of device]

 In the connecting structure of the tubular member to the rope body of the present invention, the axis of the leaf spring-like member and the axis of the rope body are substantially aligned with each other, and the end of the rope body is fitted into the leaf spring-like member to form a plate. With the spring-shaped member and the rope body pierced by the piercing member, the leaf spring-shaped member, the rope body, and the piercing member are integrally inserted into the tubular member, so that the inside of the tubular member At the inner side of the protrusion, both ends of the leaf spring member expand at least outward from the inward protrusion, and the leaf spring member and the end of the rope body integrated with the leaf spring member are pulled back from the tubular member. This prevents the tubular member from being easily and surely connected to the end portion of the rope body.
