Description

[Detailed explanation of the invention] This invention is a collection of a large number of flexible cables, hoses, etc. that supply electricity, gas, water, oil, etc. between moving parts and fixed parts of devices in mechanical equipment, etc., or between moving parts. This invention relates to flexible support devices for supporting, protecting, and guiding cables.

As shown in FIG. 1, the flexible support device disclosed in Japanese Utility Model Application Publication No. 57-40784 has two adjacent annular inner frames made of synthetic resin or aluminum alloy.
The outer frames 2a and 2b, which are divided into upper and lower parts, are sheathed one after another, and the ends of the upper and lower outer frames are connected to each other with pins 5, and the outer frame 2 is assembled.
Insert the edges 3 with both sides of a and 2b (Fig. 2) bent into the connecting groove 4 on the outside of the inner frame 1, make the width of the groove 4 larger, and insert the edges 3 at the bent portions of C, such as cables, etc. 3 is groove 4
It has a structure that allows it to move laterally inside and bend.

However, since the edge 3 is not in close contact with the bottom of the groove 4, water or oil may enter through the gap and stain the cable, or if the cable has poor insulation, it may cause a grounding or phase-to-phase short circuit. or water may enter the machine body through the cable,
There were problems such as machine breakdowns.

The object of the present invention is to provide a flexible support device for cables, etc., which solves the above-mentioned conventional problems.

In this proposal, the gap between adjacent inner frames is covered with an annular flexible seal, and the outside of the seal is covered with an outer frame divided into upper and lower halves, and both ends of the outer frame are joined together to protect the seal. It is characterized by being made to serve as both.

To explain the illustrated embodiment of the present invention below, Figures 3 to 5 show the main guide frame 6, which is generally made of synthetic resin, aluminum alloy, etc., but when supporting an electric cable, it is made of synthetic resin. shall be. The inner frame 6 has a rectangular window frame shape, and the outer periphery of the long side 6a has two wide connecting parallel grooves 7 near the center.
A narrow engagement groove 8 is formed on the outside thereof, and on the short side 6b of the inner frame 6, a groove 7 that continues to the groove 7 on one long side 6a is formed.
The outer edge 9a of the groove 7b is inclined inward toward the center of the length of the short side 6b to form a triangular groove 7a, and the inner edge 9b of the groove 7b that continues to the groove 7 on the other long side 6a is the short side. A similarly triangular groove 7b is formed toward the center of the groove 5b and inclined outward. The outer peripheral surface of the short side 6b has a groove 7
The engagement groove 8 on the short side 6b and the long side 6a form a rectangular shape.

6 to 8 show a flexible rubber or synthetic resin seal 10 covering the space between the inner frames 5,5. The seal 10 has a rectangular window frame shape, one long side 10a is wider than the other long side 10b,
A band-shaped protrusion 11 is formed on both sides of the entire circumference of the seal, and the protrusion 11 can be tightly fitted into the engagement groove 8 of the inner frame 6. Also, the outer peripheral surface 12 of the seal 10
is slightly recessed inward, and in the assembled state described later in which the protrusion 11 is fitted into the engagement groove 8 as described above,
When the mutual distance between the inner frames 6 is narrowed, the outer peripheral surface 1
2 is recessed inwardly. An insertion recess 14 for an outer frame coupling pin 13 is provided on the short side 10c of the seal 10.

The outer frames 2a, 2b have grooves 7, 7a,
7b, etc., are formed on both sides,
The upper outer frame has a U-shape that covers the long side 6a and half of both short sides 6b of the inner frame 6 as a whole, and becomes the outer side when the flexible support device is bent in the assembled state (FIG. 9), which will be described later. 2a is wider than the inner lower outer frame 2b, and when the adjacent inner frames 6, 6 are parallel as shown on the right side of FIG. ,7a
The engaging portion 3 of the lower outer frame 2b is in contact with each inner edge of the groove 7,
It is in contact with each outer edge of 7b. However, the adjacent inner frame 5
When the upper outer frame 2 is tilted, the upper outer frame 2
a tilts relative to the inner frame 6 around the terminal end of the groove 7a, and the engaging portion 3 engages with the outer edge of the grooves 7, 7a. On the other hand, the lower outer frame 2b, contrary to the upper outer frame 2a, tilts relative to the inner frame 6 around the terminal end of the groove 7b, and the engaging portion 3 is engaged with the inner edge of the grooves 7, 7b.

To assemble the flexible support device of the present invention, the protrusions 11 of the seals 10 are fitted into the engagement grooves 8 of the inner frame 6, and the inner frame 6 and the seals 10 are alternately connected.
engage and connect so that the long side 10a of 0 is on one side,
Lay the upper outer frame 2a on the seal long side 10a and the lower outer frame 2b on the long side 10b on the seal 10, insert the edges 3 into the grooves 7, 7a, 7b, etc., and then Thereafter, pins 15 are press-fitted into the holes 14 at the ends of the upper and lower outer frames 2a, 2b to connect both outer frames 2a, 2b and the inner frame 6.

In the flexible support device assembled as described above, as shown in FIG. 9, when the adjacent inner frames 6 are parallel, the long side 10a of the seal is concavely curved inward, and the long side 10b is flat. form. However, when the adjacent inner frames 6 are inclined, the long sides 10a of the seals become flat, and the long sides 10b are concavely curved inward.

Therefore, the space between the inner frames 6, 6 is closed by the flexible seal 10, and even when the flexible support device is bent, the outer frames 2a, 2b maintain the closed state and prevent damage from the outside. Protected against water and oil to reliably prevent intrusion.

This case has the above configuration, and the cables and hoses stored in the flexible support device may deteriorate or be damaged due to the intrusion of water, oil, etc., the electrical cables may have insulation breakdown, or the intruding water may damage the machinery. This has the effect of reliably preventing the risk of water flowing into the water and causing an accident.
