  As shown in FIGS. 4 and 7, the two link portions 12 (links 13) adjacent to each other in the series direction X connected to each other have a linear posture (the posture shown in FIG. 4) in which the longitudinal directions coincide with each other. Is rotated between a bending posture (the posture shown in FIG. 7) intersecting at a predetermined angle (45 degrees in this embodiment). Further, the through-hole 21 is formed so that the convex portion 20 of one link portion 12 is connected to the other link portion 12 with the rotation between the linear posture and the bent posture of the two link portions 12 adjacent in the series direction X. It has the same shape as the trajectory when moving relative to the through hole 21. Therefore, the through-hole 21 is set to the minimum necessary size.

  As shown in FIG. 4, when the two link portions 12 adjacent to each other in the series direction X connected to each other are in a linear posture, the rolling portion 27 of the convex portion 20 of one link portion 12 and the penetration of the other link portion 12 The to-be-rolled part 42 of the hole 21 is in contact.

Each is in contact.

  Thereby, since the rotation range of the two link parts 12 adjacent in the serial direction X is controlled, the linear attitude | position of these two link parts 12 is maintained. In other words, the two link portions 12 adjacent in the series direction X are restricted from rotating from the linear posture to the side opposite to the bent posture.

  On the other hand, as shown in FIG. 7, even when the two link parts 12 adjacent to each other in the series direction X connected to each other are in the bending posture, the rolling part 27 of the convex part 20 of the one link part 12 and the other link The to-be-rolled part 42 of the through-hole 21 of the part 12 is in contact.

Each is in contact.

  Thereby, since the rotation range of the two link parts 12 adjacent in the serial direction X is controlled, the bending posture of these two link parts 12 is maintained. In other words, the two link portions 12 adjacent in the series direction X are restricted from rotating from the bent posture to the side opposite to the linear posture.

Next, the operation at the time of using the cable protection guide device 11 will be described.
When the moving body (not shown) reciprocates in the series direction X, the cables protection guide device 11 reciprocates in the series direction X so that the curved portion W displaces following the moving body (not shown). To do. Then, the cables TK accommodated in the accommodation space SK are guided by the cables protection guide device 11 while being protected in accordance with the movement of the moving body (not shown). At this time, each link 13 of the cable protection guide device 11 has two link portions 12 (links 13) adjacent in the serial direction X between the linear posture and the bent posture as the curved portion W reciprocates. Is repeatedly rotated.

Then, next, the effect | action at the time of the two link parts 12 (link 13) adjacent in the serial direction X rotating between a linear attitude | position and a bending attitude | position is demonstrated according to FIGS.
When the two link portions 12 adjacent in the series direction X are rotated from the straight posture (posture shown in FIG. 4) to the bent posture (posture shown in FIG. 7), these are first bent. On the side, the other link portion 12 (the right link portion 12 in FIGS. 4 to 7) is rotated with respect to one link portion 12 (the left link portion 12 in FIGS. 4 to 7).

  Then, the to-be-rolled part 42 of the through-hole 21 of the other link part 12 rolls along the rolling part 27 of the convex part 20 of the one link part 12, and as shown in FIG. The second restriction surface 39 and the third restriction surface 40 of the through hole 21 of the other link portion 12 are separated from the second contact surface 29 and the third contact surface 30 of the twelve convex portions 20, respectively. At this time, both end surfaces in the thickness direction Z of the convex portion 20 of the one link portion 12 are guided by the first guide surface 43 and the second guide surface 44.

  Subsequently, when the other link portion 12 is rotated to the side that assumes the bending posture with respect to the one link portion 12, the rolled portion 42 of the through hole 21 of the other link portion 12 protrudes from the projection of the one link portion 12. Roll further along the rolling part 27 of the part 20. Then, as shown in FIG. 6, the first restriction surface 38 of the through hole 21 of the other link portion 12 and the first contact surface 28 and the fourth contact surface 31 of the convex portion 20 of the one link portion 12 and The fourth restriction surfaces 41 approach each other. At this time, both end surfaces in the thickness direction Z of the convex portion 20 of the one link portion 12 are guided by the first guide surface 43 and the second guide surface 44.

  Subsequently, when the other link portion 12 is rotated to the side that assumes the bending posture with respect to the one link portion 12, the rolled portion 42 of the through hole 21 of the other link portion 12 protrudes from the projection of the one link portion 12. Roll further along the rolling part 27 of the part 20. Then, as shown in FIG. 7, the first restriction surface 38 of the through hole 21 of the other link portion 12 and the first contact surface 28 and the fourth contact surface 31 of the convex portion 20 of one link portion 12 and The fourth restriction surfaces 41 are in contact with each other. Then, the rotation of the two link portions 12 adjacent in the series direction X is restricted, and the bending posture (the posture shown in FIG. 7) of the two link portions 12 is maintained.

  Further, when the two link portions 12 adjacent in the series direction X are rotated from the bending posture (the posture shown in FIG. 7) to the linear posture (the posture shown in FIG. 4), first, these become the linear posture. On the side, the other link portion 12 is rotated with respect to the one link portion 12. Then, the to-be-rolled part 42 of the through-hole 21 of the other link part 12 rolls along the rolling part 27 of the convex part 20 of the one link part 12, and as shown in FIG. The first restriction surface 38 and the fourth restriction surface 41 of the through hole 21 of the other link portion 12 are separated from the first contact surface 28 and the fourth contact surface 31 of the twelve convex portions 20, respectively. At this time, both end surfaces in the thickness direction Z of the convex portion 20 of the one link portion 12 are guided by the first guide surface 43 and the second guide surface 44.

  Subsequently, when the other link portion 12 is rotated with respect to the one link portion 12 to the side that assumes a linear posture, the rolled portion 42 of the through-hole 21 of the other link portion 12 is protruded from the one link portion 12. Roll further along the rolling part 27 of the part 20. Then, as shown in FIG. 5, the second restriction surface 39 of the through hole 21 of the other link portion 12 and the second contact surface 29 and the third contact surface 30 of the convex portion 20 of the one link portion 12 and The third restriction surfaces 40 approach each other. At this time, both end surfaces in the thickness direction Z of the convex portion 20 of the one link portion 12 are guided by the first guide surface 43 and the second guide surface 44.

  Subsequently, when the other link portion 12 is rotated with respect to the one link portion 12 to the side that assumes a linear posture, the rolled portion 42 of the through-hole 21 of the other link portion 12 is protruded from the one link portion 12. Roll further along the rolling part 27 of the part 20. Then, as shown in FIG. 4, the second restriction surface 39 of the through hole 21 of the other link portion 12 and the second contact surface 29 and the third contact surface 30 of the convex portion 20 of one link portion 12 and The third restriction surfaces 40 are in contact with each other. Then, the rotation of the two link portions 12 adjacent in the series direction X is restricted, and the linear posture (the posture shown in FIG. 4) between the two link portions 12 is maintained.

  As described above, in the cables protection guide device 11, as the two link portions 12 adjacent in the series direction X rotate, the rolled portion 42 of the through hole 21 of the other link portion 12 is one link portion. It rolls along the rolling part 27 of the 12 convex parts 20. For this reason, the wear of the through-hole 21 and the convex part 20 is suppressed, and by extension, the wear of the link part 12 is suppressed.

According to the embodiment detailed above, the following effects are exhibited.
(1) In the cables protection guide device 11, the rolling part 42 of the through-hole 21 of the other link part 12 is connected to one link part as the two link parts 12 adjacent in the series direction X rotate. It rolls with respect to the rolling part 27 of the 12 convex parts 20. For this reason, it is possible to suppress wear of the through holes 21 and the protrusions 20 of each link portion 12 as compared with the conventional configuration in which the link portions 12 are rotated by sliding between the connecting pin and the connecting pin hole. As a result, wear of each link portion 12 can be suppressed. As a result, it is possible to extend the life against the bending of the cable protection guide device 11. In addition, since the sliding amount associated with the rotation of the two link portions 12 adjacent in the series direction X can be significantly reduced, the generation of sliding noise between the link portions 12 and the link portions 12 Generation of dust (scraping waste) due to sliding can be greatly reduced. As a result, the cables protection guide device 11 can be operated at high speed.

  (2) In the cable protection guide device 11, when the two link portions 12 adjacent in the series direction X are in a linear posture, the second contact surface 29 of the convex portion 20 of the one link portion 12 and the third contact portion The contact surface 30 is in contact with the second restriction surface 39 and the third restriction surface 40 of the through hole 21 of the other link portion 12. Furthermore, when the two link portions 12 adjacent in the series direction X are in the bending posture, the first contact surface 28 and the fourth contact surface 31 of the convex portion 20 of the one link portion 12 are the other link portions 12. The first restriction surface 38 and the fourth restriction surface 41 of the through hole 21 are in contact with each other. For this reason, the rotation range of the two link portions 12 adjacent in the series direction X can be restricted from a straight posture to a bent posture. That is, the rotatable range of the two link portions 12 adjacent in the series direction X can be set only between the linear posture and the bent posture.

  (3) In the cable protection guide device 11, the two link portions 12 adjacent in the series direction X have the convex portion 20 of the one link portion 12 and the other link portion 12 in both the linear posture and the bent posture. The two through holes 21 come into contact with each other at two locations. For this reason, while being able to perform regulation of the rotation range of two link parts 12 adjacent in the serial direction X stably, the rigidity of cable protection guide device 11 can be raised.

  (4) In the cable protection and guide device 11, the rolling part 27 and the rolled part 42 of each link part 12 are both configured by convex curved surfaces. For this reason, the to-be-rolled part 42 can be efficiently rolled with respect to the rolling part 27 with rotation of the two link parts 12 adjacent in the serial direction X. That is, the driven part 42 can be smoothly rolled with respect to the rolling part 27.

You may comprise so that it may roll with respect to the to-be-rolled part 42 of 21.

  When the two link portions 12 adjacent to each other in the series direction X connected to each other are in a straight posture, the second contact surface 29 and the third contact surface 30 of the convex portion 20 of one link portion 12 are the other link. You may make it contact | abut to the 2nd control surface 39 and the 3rd control surface 40 of the through-hole 21 of the part 12, respectively.
