  However, the conventional cable protection guide device exemplified in Patent Document 1 is a so-called horizontal cable in which cables are moved back and forth along the cable longitudinal direction and the horizontal floor surface between the cable fixed end and the cable moving end. When used in bending, the upper link plate and the lower link plate constituting the link frame are separated from each other in the vertical direction, and the lower link plate excessively slides along the horizontal floor surface. There has been a problem that the bottom surface portion of the link plate, the connecting pin portion, and the like are damaged, making it difficult to move the cables by bending back along the horizontal floor surface and significantly deteriorating the durability of the device itself.

  In addition, if the bottom link plate of the lower link plate, the connecting pin portion, etc. are damaged, the movement load between the cable fixing end and the cable moving end increases, or the bending back movement along the horizontal floor surface increases. In this case, there is a problem that not only the sliding noise is greatly increased, but also the cables need to be removed when replacing the apparatus itself, and the work load of maintenance is significantly increased.

  Therefore, the present invention solves the conventional problem, that is, the object of the present invention is to connect the cables inserted through the link frame to the lower link plate between the cable fixing end and the cable moving end. Provided is a horizontal bent cable protection guide device that simplifies the locking mechanism of the shoe and simplifies maintenance and maintenance, while smoothly bending back and moving along the horizontal floor surface without causing direct sliding contact with the horizontal floor surface.

In addition, the following unique effects can be achieved.

  First, according to the present invention, the lower link plate is provided with a shoe that exhibits higher wear resistance than the lower link plate and moves in sliding contact with the horizontal floor surface. Since the shoe, which has higher wear resistance than the lower link plate, does not slid directly on the surface, it slidably contacts the horizontal floor surface. The cable can be bent and moved smoothly along the longitudinal direction of the cable and along the horizontal floor surface, and even if the shoe is worn, maintenance can be easily achieved by replacing only the shoe.

  According to the first aspect of the present invention, in addition to the effects described above, the shoes are assembled in a holding state from both sides of the lower link plate. The shoe that protrudes from the outer side of the link frame when it is bent back and moved along the horizontal floor between the cable fixed end and the cable moving end precedes the link frame and the periphery in the horizontal floor. Since the member is in sliding contact with the member, the link frame body can be prevented from being damaged by avoiding contact between the link frame body and the peripheral members in the horizontal floor surface.

  According to the invention of claim 2, in addition to the above-described effect, the shoe is locked to the engaging portion between the lower link plate and the connecting plate, so that the shoe is connected to the lower link plate. Since the engaging portion with the connecting plate is covered and protected, it is possible to prevent the lower link plate and the connecting plate from being inadvertently dropped and to simplify the shoe locking mechanism.
