In particular, it is preferable that the link frame is integrally formed of resin.

Below, the cable protection guide apparatus of this invention is demonstrated based on drawing.
As shown in FIG. 1, a cable protection and guide device 100 according to an embodiment of the present invention includes a pair of left and right link plates 110 that are spaced apart from each other and a horizontal bridge that is horizontally placed between the pair of link plates 110. A large number of rectangular link frames 101 made of a plate 120 are connected to each other by a connecting pin 111 and a connecting pin hole 112 provided on the link plate 110 so as to be rotatable with respect to each other. And the cable frame 101 is inserted into a cable housing space formed by connecting the link frame bodies 101 to be protected and guided.

  As shown in FIGS. 2 to 7, the pair of left and right link plates 110 of the link frame 101 includes an inner plate portion 115 having a connecting pin 111, an outer plate portion 116 having a connecting pin hole 112, and the like. The inner plate portion 115 and the outer plate portion 116 are connected on the bent outer peripheral side, and have a bent outer peripheral elastic portion 117 that can be deformed and bent in the rotating direction.

  Further, the inner plate portion 115 is provided with a rotation angle restricting convex portion 114, and the outer plate portion 116 is provided with a turning angle restricting concave portion 113. It is comprised so that the rotation angle when mutually connected rotatably can be controlled.

The pair of left and right link plates 110 includes a horizontal plate 120 that connects the bent outer peripheral sides of the inner plate portions 115 and a reinforcing horizontal girder 122 that connects the bent outer peripheral sides of the outer plate portions 116. , Each of the inner plate portions 115 has a horizontal plate 121 extending from the bent inner peripheral side and having an intermediate portion divided into left and right by a slit 123.
Thus, the link frame body 101 having a rectangular cable housing space is constituted by the pair of left and right link plates 110, the horizontal plate 120, the reinforcing cross beam 122, and the horizontal plate 121.

As shown in FIG. 8, the link plate 110 is configured such that a bent outer peripheral side elastic portion 117 connecting the inner plate portion 115 and the outer plate portion 116 can be deformed and bent in the rotation direction by the connecting pin 111 and the connecting pin hole 112. ing.
Then, the bent outer peripheral side elastic portion 117 of the pair of left and right link plates 110 is deformed and bent, so that the link frame body 101 is deformed and bent while maintaining the cable housing space, and the cable protection guide device 100 as a whole is linked to the link plate 110. It is possible to obtain a bending radius smaller than the bending radius defined by the rotation angle restricting convex portion 114 and the rotation angle restricting concave portion 113 without shortening the front and rear length of the lens and without increasing the link plate 110.

Can be bent in both directions.
For this reason, even when the frames 102 and 103 are configured on an arc by a turning device or the like, it is possible to use a frame designed for a linear frame without any special design change.

  Furthermore, since the middle of the horizontal plate 121 extending from the inner side of each inner plate portion 115 is divided by the slit 123, the cables can be easily attached to and detached from the accommodation space.

  The reinforcing cross beam 122 may be omitted depending on the rigidity required for the link frame body 101. The horizontal plate 120 and the horizontal plate 121 may be either the inner plate portion 115 or the outer plate portion 116, respectively. May be provided on either one or both.

  As described above, according to the cable protection guide device of the present invention, the rotation angle defined for the entire cable protection guide device is reduced without shortening the longitudinal length of the link plate and without increasing the link plate. The effect is enormous, for example, it can be bent beyond the range and the bending radius can be reduced, and the assembly and maintenance can be facilitated with a simple structure.
