  The details of the cable support according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a perspective view of the cable support 1 in use. The support 1 is fixed to the peripheral surface 3 (see FIG. 3) of the utility pole indicated by the phantom line by the belt 2 indicated by the phantom line. The support 1 includes a holder portion 6 that is in close contact with the peripheral surface 3, a cap portion 7 that can be opened and closed with respect to the holder portion 6 and is closed in the figure, and the holder portion 6 and the cap portion 7. And two strip-shaped connector portions 8 connecting the two. For example, a plurality of optical communication cables 9 including a core 11 and a sheath 12 shown in the figure can be attached to the holder portion 6, and one cable 9 is shown by a solid line in the figure, and another cable 9 is shown. The cable 9 is indicated by a virtual line. The attached cable 9 is covered with a cap portion 7.

  FIG. 2 is a perspective view of the support 1 in a state in which the cap portion 7 is opened with respect to the holder portion 6. The holder portion 6 of the support 1 is opposed to the strip-shaped portion 21 extending in the direction Q around the peripheral surface 3 of the utility pole and curved so as to form an arc along the peripheral surface 3 in the length direction P of the utility pole. In this way, the cable support portion 22 standing in a pair and standing from the edge of the belt-like portion 21 and the stopper portion 23 connecting the pair of support portions 22 and extending in the length direction P of the utility pole are provided. A plurality of the support portions 22 are formed in the direction Q around the peripheral surface 3. The belt-like portion 21 is flexible so that it can be bent along the peripheral surface 3 of a plurality of utility poles having different diameters, and a portion that faces the stopper portion 23 penetrates the belt-like portion 21 in the thickness direction. A hole 24 is formed (see FIG. 3). The through hole 24 extends from one of the paired support portions 22 to the other. Each of the support portions 22 is formed with a substantially C-shaped recess 26, and an opening 27 in the C-shape is formed at the top portion 28 of the support portion 22. The concave portion 26 allows the cable 9 to be inserted and removed through the opening 27 in the radial direction of the utility pole. When the cable 9 is inserted, the support portion 22 is elastically deformed so that the opening 27 opens greatly in the direction Q. The sheath 12 of the cable 9 is elastically deformed so that the diameter becomes small. Similarly, when the cable 9 is pulled out from the support portion 22, it is also elastically deformed. Since a plurality of pairs of support portions 22 are formed in the belt-like portion 21, when the cables 9 are inserted into the respective support portions 22, the plurality of cables 9 extending in the length direction P of the utility pole are parallel to each other and orderly (See FIG. 1).

  The cap portion 7 is provided on the outer side of the support portion 22 so as to cover the cable 9 supported by the support portion 22 and the support portion 22 from above in the state of FIG. It has a pair of side wall part 32 which is located, and a pair of end wall part 33 which connects the side wall part 32. The covering portion 31 has a hook 37 that extends so as to hang down toward the strip portion 21 on the inner surface 36 that faces the strip portion 21 of the holder portion 6 in the state of FIG. 1. The hook 37 is drawn so as to stand up from the inner surface 36 of the covering portion 31 in FIG. 2, and the covering portion 31 is formed with a through hole 38 extending along the proximal end portion of the hook 37. The side wall portion 32 is formed so as to hang from the covering portion 31 between the adjacent concave portions 26 and 26 in the holder portion 6 of FIG. 1, and a portion facing the concave portion 26 is notched in a U shape. . The side wall portions 32 facing each other with the covering portion 31 interposed therebetween may be connected via the reinforcing rib 39. Such a cap portion 7 covers the support portion 22 and the cable 9 to protect them from wind and rain and ultraviolet rays.

  The pair of connector portions 8 extend in parallel to each other from the end portion of the band-like portion 21 in the holder portion 6 to one of the pair of end wall portions 33 in the cap portion 7. The separation dimension B between the connector parts 8 is the same as or larger than the separation dimension A between the pair of support parts 22 in the holder part 6. Therefore, as long as the belt 2 for fixing the support 1 to the peripheral surface 3 of the utility pole fits between the support portions 22 facing each other in the holder portion 6 and abuts against the belt-like portion 21, the connector portion 8. And 8 can pass through. The support 1 in which the belt 2 and the connector portion 8 are in such a state is not easily detached from the belt 2.

  3 and 4 are a sectional view taken along line III-III in FIG. 1 and a sectional view taken along line IV-IV in FIG. In the support 1 in which the cap portion 7 shown in FIG. 3 is closed with respect to the holder portion 6, the hook 37 of the cap portion 7 is snap-engaged with the stopper 23 of the holder portion 6 so that the cap portion 7 opens. Suppressing movement. However, the cap portion 7 is detached from each of the stoppers 23 by elastically deforming each of the hooks 37 when a finger is applied to the end wall portion 33 located on the left side of the figure and lifted strongly in the direction of arrow C. Subsequently, the bent connector portion 8 can be extended and opened as shown in FIGS. When the open cap portion 7 is turned in the direction of arrow D so as to be directed to the holder portion 6 in FIG. 4, the hook 37 abuts against an appropriate one of the stoppers 23 and elastically deforms, and as shown in FIG. It will be in the engaged state. The holder portion 6 has a clearance 40 through which the belt 2 can be passed between the belt-like portion 21 and the stopper 23. If the belt 2 is passed through the clearance 40, the support 1 is not easily detached from the belt 2.

  As is apparent from FIGS. 2 and 4, a groove 43 extending in the length direction P of the utility pole is formed on each of the inner surface 41 and the outer surface 42 of the belt-like portion 21 of the holder portion 6 that is in close contact with the peripheral surface 3 of the utility pole. 44 is formed. These grooves 43 and 44 are provided so that the belt-like portion 21 can be easily bent in the direction Q around the peripheral surface 3. In the figure, the length direction of the utility pole across the through hole 24 in the belt-like portion 21. Examples are grooves 43a and 44a formed so as to extend to P, and grooves 43b and 44b formed so as to extend longitudinally through the belt-like portion 21 at portions where the through holes 24 are not formed. In the case where the depths of the grooves 43 and 44 are constant, the belt-like portion 21 has grooves 43a and 44a extending across the through holes 24, so that the bending thereof becomes particularly easy. This is because the belt-like portion 21 in the portion where the grooves 43a and 44a are formed has less material to be curved than the portion where the grooves 43b and 44b are formed. However, in the present invention, only one of the grooves 43a, 44a and 43b, 44b is provided in the belt-like portion 21, only the grooves 43a, 43b are provided, or only the grooves 44a, 44b are provided. It is possible to provide only one groove. Further, when the belt-like portion 21 is formed of a material that can be easily bent, the present invention can be carried out by omitting the grooves 43 and 44.

  In the support 1 having such a structure, the holder portion 6, the cap portion 7, and the connector portion 8 are integrally formed by injection molding a flexible thermoplastic synthetic resin such as polyethylene, polypropylene, nylon, and ABS. Can be made. Such a support 1 is not only easy to manufacture, but also the belt 2 is passed between the pair of connector portions 8 in advance, or the belt 2 is passed through the clearance 40 in advance, such as a utility pole. If it is attached at a high place, the support tool 1 is not accidentally dropped during the attaching operation. Each of the through hole 24 in the belt-like part 21 and the through hole 38 in the cap part 7 not only facilitates the bending of the support tool 1 but also a stopper in the holder part 6 when the support tool 1 is manufactured by injection molding. 23 and the formation of the hook 37 in the cap portion 7 can be facilitated. In the present invention, the connector portion 8 for connecting the holder portion 6 and the cap portion 7 can be changed from the two strip-shaped portions in the illustrated example to the one strip-shaped portion. Since there is no special rule about the length of these strip | belt-shaped parts, the length can be set freely. Furthermore, the present invention can also be implemented by omitting the connector portion 8 and separating the holder portion 6 and the cap portion 7 from each other.

  According to the present invention, it is possible to manufacture a cable support capable of fixing a plurality of cables extending in the length direction of a columnar object such as a power pole in parallel to each other on the peripheral surface of the columnar object.
