On the other end of the unit member 10, narrower parallel walls 16c, 16d are formed and a pair of engaging pins 20 are provided on them. Thereby, by inserting the narrower parallel walls 16c, 16d of one unit member 10 adjoiningly between the wide parallel walls 16a, 16b of another unit member 10 and inserting the engaging pins 20 into the pin holes 18, each of the unit members can be rotatably connected, forming a guide chain.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cable/hose guide chain, and more particularly to a cable/hose guide chain for orderly and reliable support and guidance of cables, bows, etc. that supply energy to moving parts of mechanical equipment. It's about chains.

Traditionally, cables and hoses that supply energy such as large amounts of electricity or compressed air to moving parts of machinery have been used as cables and hoses.
A guide chain is known that guides and supports hoses and the like so that they follow the movement of a target machine to prevent them from being bent or tangled. This guide chain consists of a large number of short unit members each having a through hole through which a cable/hose is inserted and supported in the axial direction. A guide chain for cables and hoses that connects the ends of members so that they can rotate freely within a predetermined plane (hereinafter referred to as guide chain)
There is. However, in conventional guide chains, the ends of adjacent unit members are irreparably joined with steel pins, etc., so the length of the guide chain can be adjusted by fitting various mechanical devices. It was difficult to adapt it by lengthening or shortening it at will.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to connect the ends of a large number of adjacent unit members constituting the above-mentioned guide chain so that they can be separated and joined together, The length of the guide chain can be lengthened or shortened as desired by separating the unit members of a predetermined part of the guide chain or adding other unit members to the predetermined part of the guide chain to suit various mechanical devices. One end of each connecting part of the unit member is formed into a narrow width and the other end is formed into a wide parallel wall, and an engaging pin and a pin hole are formed on the circular outer surface of the narrow parallel wall and the circular inner surface of the wide parallel wall. To provide a guide chain for a cable/hose, characterized in that a coupling rotation part is provided, and an outer wall of a narrow parallel wall of an adjacent unit member is rotatably engaged with a pin inside a wide parallel wall. There is a particular thing.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Figures 1 to 3 show unit members constituting the guide chain of the present invention, and the unit member 10 is made of, for example, a flexible synthetic material. It is formed using a resin material, and its overall shape forms a substantially rectangular frame shape consisting of a connecting rotation part 16 and a ring part 14, and a through hole 12 wide in the axial direction of the frame body through which a cable, hose, etc. is inserted. is formed.

The upper end surface of the unit member 10 is curved outward from the upper part of the connecting rotation part 16 formed on the parallel wall of the unit member 10, for example.
Furthermore, a ring portion 14 is formed that extends horizontally toward the center of the upper surface of the unit member 10. The ring portion 14 is made up of two flexible thin plate-like parallel extending frames 14a and 14b, which are separated approximately at the center. Wide parallel walls 16a and 16b are formed at one end of the connecting and rotating portion 16, and a bottle hole 18 is bored at the tip of the wide parallel walls 16a and 16b. Further, narrow parallel walls 16C and 16d are formed at the other end of the unit member 10, and the narrow parallel walls 16C and 16d are provided with wide parallel walls 16C and 16d of the unit member 10 connected adjacent to the unit member 10. walls 16a and 16b
A pair of engagement pins 20 that are loosely inserted and locked in each bottle hole 18 of
It is bored to match the position of the bottle hole 18.

Accordingly, the guide chain of the present invention is constructed by connecting a large number of unit members 10 having the above configuration in a line as shown in FIG. 4, and between wide parallel walls 16a and 16b at one end of each unit member The narrow parallel walls 16C and 16d of the unit member 10 adjacent to the unit member 10 are inserted into the pin holes 18 of the wide parallel walls 16a and 16b at the end of each unit member 10 of the other unit member. The engagement pins 20 of the narrow parallel walls 16c and 16d at the ends of 10 are loosely inserted and locked,
Ends of adjacent unit members 10 are pin-engaged to be rotatable within a predetermined plane. To separate the pin-engaged long guide chain at an appropriate position,
The pin hole 18 is expanded by pushing outward the flexible wide parallel walls 16a and 16b of each unit member 10.
The engagement pins 20 of the narrow parallel walls 16c and 16d at the other end of the adjacent unit member 10 need only be removed from the inside, and conversely, in order to join them, the above-mentioned wide parallel walls 16 on the left and right sides should be removed.
Adjacent unit members 1 in each pin hole 18 of a and 16b
The engagement pins 20 of the narrow parallel walls 16C and 16d at the other end of the connector 0 may be loosely inserted and locked.

In this way, adjacent unit members 10 in any part of the guide chain can be freely joined and separated.

Therefore, when using it, one end of a guide chain of an appropriate length is fixed to the movable part of the mechanical device, and
The other end is fixed to a predetermined fixed part of the mechanical device, and the guide chain is connected between the movable part and the fixed part of the mechanical device by appropriately bending the middle part of the guide chain within a predetermined plane, and Extension frames 14a and 14b covering the upper part of the through hole 12 of the ring portion at an appropriate position in the guide chain
The extension frame 14a is bent and pushed open by bending the central part of the extension frame 14a.
Insert a cable, hose, etc. along the through hole 12 of each unit member 10 of the guide chain from the central part of the guide chain 14b, or insert a cable, hose, etc. from the end of the guide chain along the through hole in the guide chain. Cables, hoses, etc. that are inserted through the guide chain and connected to the movable parts of mechanical equipment are guided and supported along the inside of the guide chain.

In the above embodiment, in order to provide flexibility to the wide parallel walls 16a and 16b of the unit member 10 constituting the guide chain, the entire unit member 10 is made of a flexible synthetic resin material. However, in some cases, only the portions of the unit member 10 near the wide parallel walls 16a and 16b may be made of flexible members. Furthermore, the engaging pins 20 may be provided in the wide parallel walls 16a and 16b of the unit member 10, and the pin holes 18 may be provided in the narrow parallel walls 16C and 16d.

Furthermore, the through holes 12 for guiding and supporting cables, hoses, etc. provided in the axial direction of the unit member 10 are not formed in a cylindrical shape, but are provided on the surface of a flat plate, etc., in the unit member 1.

Alternatively, the upper part of the through hole 12 may be configured with a fixed frame so that it cannot be opened, and a cable, hose, etc. may be inserted into the guide chain only through the end of the guide chain.

As described above, in the guide chain of the present invention, the ends of each unit member constituting the guide chain are connected so that they can be joined and separated, so various mechanical devices can be attached according to the parts. Its total length can be easily adjusted to lengthen or shorten.

In addition, damaged unit members can be replaced,
Even when transporting, it is possible to separate the long guide chain in the middle, transport it, and rejoin it at the site, etc., making transport work easier than with conventional chains. It has great effects such as becoming.

Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.
