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 reliably supporting and guiding cables/bosses, etc. that supply energy to moving parts of mechanical equipment.
It concerns the Bose guide chain.

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 large number of short rings each having a through hole for inserting and supporting the cable/hose in the axial direction to guide and support the cable/hose so that it follows the movement of the target machine so that the hose, etc. does not bend or get tangled, is attached to each adjacent ring. A guide chain (hereinafter referred to as a guide chain) of cables and hoses arranged in a line with the central axes of the through holes of the unit members aligned and rotatably connected between the ends of each adjacent unit member within a predetermined plane. be.

However, in conventional guide chains, the peripheral portion of the through hole through which cables, hoses, etc. of adjacent unit members are inserted and locked is completely surrounded by a steel frame, etc., and each unit member of the guide chain To insert cables, hoses, etc. into the guide chain through the through-holes, normally the guide hose is stretched out in a straight line, placed on a flat surface, etc., and the cable or hose is inserted from one end of the guide hose to the other end. etc. must be sequentially passed through through holes provided in the axial direction of each unit member of the guide chain and inserted along the inside of the guide chain, which is complicated and takes a lot of time. Also,
If the cable or hose in the guide chain is damaged and needs to be repaired or replaced, remove both ends of the guide chain from the fixed and movable parts of the mechanical device, and remove the cable or hose in the guide chain. The guide chain must be pulled out from the end of the guide chain for repair or replacement, and it requires a great deal of time and effort to insert cables, hoses, etc. into the guide chain.

The present invention has been made in view of the above-mentioned problems, and its purpose is to appropriately press open the ring portion covering the through hole through which the hoses and cables of each unit member constituting the guide chain are inserted, and to open the ring portion from the top of the through hole. A plurality of appropriate unit members consisting of a ring part and a connecting part, through which cables, hoses, etc. can be easily and freely inserted along the inside of the guide chain, are arranged in a chain shape at the connecting part so that the unit members can be deformed as a whole within the same plane. A cable/hose guide chain that supports and connects each unit member and is characterized in that the ring part of each unit member is formed of a flexible member and that the ring part is provided with a cutting part so that the cable, hose, etc. can be pushed into the ring part. Our goal is to provide the following.

Hereinafter, embodiments of the present invention will be described in detail according to the drawings.
3 to 3 show unit members constituting the guide chain of the present invention. The unit member 10 is formed using, for example, a flexible synthetic resin material, and its overall shape is similar to that of the connecting portion 16 and the ring. It has a substantially rectangular frame shape consisting of a section 14, and a through hole 12 is formed in the frame in the axial direction to allow a cable, hose, etc. to pass therethrough. The upper end surface of the upper part of the through hole of the unit member 10 curves outward from the upper part of the connecting part 1G formed in the parallel wall of the unit member 10, and
Ring portion 14 extending horizontally toward the center of the upper surface of 0
is formed. Wide parallel walls 16a and 16b are formed at one end of the connecting portion 16, and the wide parallel walls 16
Bottle holes 18 are bored at the tips of a and 16b. Furthermore, narrow parallel walls 16c and 16d are formed at the other end of the unit member 10, and these narrow parallel walls 16c and 16d are formed at the other end of the unit member 10.
．． 6 d, a pair of engaging pins 20 are loosely inserted into and locked in each of the bottle holes 18 in the wide parallel walls 16 a and 16 b of the unit member 10 adjacent to and pivotally connected to the unit member 10 . It is drilled according to the position of

Therefore, the guide chain of the present invention is constructed by connecting a large number of unit members 10 having the above-mentioned configuration in a line as shown in FIG. , the narrow parallel walls 16c and 16d of the adjacent unit parts @10 are inserted into each pin hole 18 of the wide parallel walls 16a and 16b of the unit member 10,
Narrow parallel walls j6C and 16 of adjacent unit members 10
The engagement pin 20 of d is loosely inserted and locked, and the ends of the adjacent unit members 10 are pivotally connected to each other so as to be rotatable within a predetermined plane. Also, if the wide parallel walls 16a and 16b are pushed outward, they can be joined together.

Separation is possible.

The ring portion 14 of each unit member 10 constituting the guide chain consists of two flexible thin plate-shaped parallel extending frames 14a and 1-4b. A cutting portion 22 formed of an extremely thin plate-like member that can be separated is provided approximately in the center. This cutting section 2
2 facilitates molding of the ring portion 14 using a synthetic resin material, and also prevents deformation of the ring portion 14 during assembly of the guide chain.

Therefore, when using it, one end of a guide chain of an appropriate length is fixed to a movable part of a mechanical device, the other end is fixed to a predetermined fixed part of a mechanical device, and the guide chain is A guide chain connects a movable part and a fixed part of a mechanical device by bending them appropriately within a predetermined plane, and each ring part 1 of the connected guide chain
Using a knife or the like, cut the cutting portion 22 that connects the approximately central portions of the extension frames 14a and 14b of No. 4 to the extension frame 14a.
and 14b are bent and pushed open, and cables, hoses, etc. are inserted into the through holes 12 of each unit member 10 that are penetrated along the guide chain between the pushed open extension frames 14a and 14b. Then, cables, ports, etc. connected to the flexible parts of the mechanical device are supported and guided along the guide chain. Alternatively, a cable, hose, etc. may be inserted from the end of the guide chain along the through hole 12 in the guide chain.

In the above-mentioned embodiment, in order to provide flexibility to the extension frames 142 and 14b that cover the upper part of the through hole 12 of the unit member 10 constituting the guide chain, the entire unit member is made of flexible synthetic resin. However, in some cases, only the vicinity of the extension frames 14a and 14b of the unit member 10 may be made of a visible member.

Further, the number of extending frames of the ring portion 14 of the unit member 10 may not be two, but may be only one.

Furthermore, if the ring portion 14 is formed to be thick and difficult to deform, the cutting portion 22 at the center of the extension frames 14a and 14b is not provided from the beginning, and the unit member 1o that constitutes the guide chain is separated. May be manufactured.

Furthermore, the unit members 10 constituting the guide chain may also be rotatably joined using other structural members such as stop pins.

As described above, the guide chain of the present invention is configured such that the approximately central portion of the ring portion that covers the upper part of the through hole through which the hose or cable of each unit member is inserted can be separated and pushed open left and right. Cables, hoses, etc. can be inserted into the through hole through which the upper end surface of the pushed-open ring passes along the inside of the guide chain, and the cables, hoses, etc. that are inserted and supported along the inside of the guide chain can be inserted in the middle of the guide chain. By pushing open the upper end surface of the through hole of the unit member at an appropriate position, the guide chain can be easily inserted from the middle part along the guide chain. Also, when repairing or replacing a damaged cable, hose, etc. in the guide chain, push open the two ends of the through hole of the unit member in the damaged part and take out the cable, hose, etc. of the unit member and repair it. It is possible to repair or replace the cable, bow, etc. inserted in the guide chain, and it has great effects such as easy repair and replacement.

Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. I'm talking about.
