Description

[Technical Field]

[0001] The present invention relates to a cable hanger for attaching a cable. [Background technology]

[0002] A cable hanger may be used to wire or route cables in work spaces such as above the ceiling or under the floor. Here, cables include distribution cables such as electric wires and telephone lines, as well as flexible wire protection tubes that cover these cables. A known example of such a cable hanger is the cable hanger disclosed in Patent Document 1. This cable hanger includes a rod-shaped operating handle and a hook at the end of the operating handle.

[0003] One type of work involving wiring cables using a cable hanger is staggered wiring work. This staggered wiring work will be explained using FIG. 3. Here, FIG. 3 is an explanatory diagram for explaining the staggered wiring work. FIG. 3A is an explanatory diagram of the points for hooking cable 50, FIG. 3B is an explanatory diagram of cable 50 after wiring, and FIG. 3C is an explanatory diagram of a state in the middle of another staggered wiring work procedure.

[0004] As shown in Fig. 3A, points are provided in a facility or the like where cable 50 is to be laid. These points are, for example, locations where lighting fixtures are installed. Points A to E in Fig. 3A are points for hooking cable 50, and cable 50 is laid between each of these points.

[0005] In a typical procedure for wiring cable 50, the worker first provides a looped cable end at the tip of cable 50 to be wired. The worker hooks the cable end onto the hook of a cable hanger. The worker pulls cable 50 from point A to point B using the hook of the cable hanger, and temporarily secures the cable end at point B. Here, temporarily securing refers to securing the cable so that it can move freely, for example, by passing the cable through a circular wiring member (the same applies hereinafter). Next, the worker similarly repeats the process from point B to point C, from point C to point D, and from point D to point E, and finally secures the terminal point E, thereby wiring cable 50 from point A to point E (see FIG. 3B ).

[0006] This work procedure has the advantage that it is possible to accurately lay the V-shaped cable and to lay the cable 50 without wasting any length. However, this general zigzag wiring work requires the worker to move to each point, which takes time. To shorten this work time, the following other work procedure is known:

[0007] In this alternative work procedure, first, a worker hooks the cable end into a hook, temporarily fastens the cable end at point C, and then fixes it to point E, which is the termination point (see FIG. 3C). Next, the worker hooks cable 50 between points C and E into a hook, pulls the hooked cable 50 in the direction of the arrow, and temporarily fastens cable 50 to point D. Next, the worker hooks the cable between points A and C into a hook, and temporarily fastens the hooked cable 50 to point B, thereby completing the wiring of cable 50 between points A and E (see FIG. 3B). This work procedure also reduces the distance the worker has to travel, thereby shortening the work time. [Prior art documents] [Patent documents]

[0009] However, in the above-described procedure, as shown in FIG. 3C , tension is applied to cable 50 between points C and E. When temporarily securing cable 50 between points C and E to point D, it is difficult to control the amount of force used to pull cable 50 toward point D. This can result in more cable 50 being pulled toward point D than necessary, resulting in wasted cable 50. For ease of explanation, FIG. 3 shows points A through E. However, in actual work, there are many points. While this procedure effectively reduces work time, the total amount of cable wasted by pulling extra cable between each point, resulting in significant costs. Furthermore, because cable 50 is under tension, there is a risk of damaging the cable itself when pulling cable 50 toward point D.

[0010] In order to solve the above problems, the present invention aims to provide a cable hanger that is efficient in cable wiring work, prevents damage to the cable, improves the efficiency of staggered wiring work, and further allows the hook portion to be easily replaced. [Means for solving the problem]

[0011] The cable hanger according to the present invention is a cable hanger for attaching a cable, and includes a rod-shaped operating handle and a handle provided at an end of the operating handle. Ta and a linear hook portion, the hook portion having an arc-shaped portion that opens toward the operating handle portion, teeth Rotatable cylindrical rotating part The arc-shaped portion has the rotating portion is journalled, and the rotating part is When the cable is expanded from the center in the longitudinal direction toward each end of the rotating part and pulled by the hook part, To the cable It comes into contact with the cable and moves while rotating on it. It is characterized by:

[0013] In the cable hanger, the hook portion is detachable from the operating handle portion. [Effects of the Invention]

[0014] The cable hanger of the present invention prevents cable damage during cable wiring work and improves the efficiency of staggered wiring work. Furthermore, the rotating part expands from the longitudinal center toward each end of the rotating part, so the cable can be securely gripped. Furthermore, the hooking part is detachable from the operating handle, so that hooking parts used in other cable hangers can be used. [Brief explanation of the drawings]

[0015] [Figure 1] 1 is a perspective view showing a cable hanger according to an embodiment of the present invention. [Figure 2] 10A and 10B are diagrams showing a state in which a cable is hooked by the cable hanger according to the embodiment of the present invention. [Figure 3] FIG. 10 is an explanatory diagram for explaining a staggered wiring operation. DETAILED DESCRIPTION OF THE INVENTION

[0016] <Description of the Configuration of Cable Hanger 10> A cable hanger 10 according to an embodiment of the present invention will now be described with reference to Figures 1 and 2. Figure 1 is a perspective view showing the cable hanger 10 according to an embodiment of the present invention, and Figure 2 is a diagram showing the state in which a cable 50 is hung by the cable hanger 10 according to an embodiment of the present invention.

[0017] The cable hanger 10 includes an operating handle 12, a hook 14, and a rotating part 16. The operating handle 12 is rod-shaped and made of, for example, stainless steel. The operating handle 12 is extendable to a length of approximately 2 m to approximately 15 m.

[0018] The hook portion 14 is a linear member for hooking the cable 50. The hook portion 14 is detachably attached to the end of the operating handle portion 12 and has an arc-shaped portion 18. The arc-shaped portion 18 is an arc-shaped member that is open on the operating handle portion 12 side. The rotating portion 16 is journaled on the arc-shaped portion 18. The rotating portion 16 is a cylindrical member that is rotatable relative to the arc-shaped portion 18.

[0019] <Description of How to Use the Cable Hanger 10> Next, a description will be given of how to use the cable hanger 10. First, the worker fixes the cable 50 to point E via a temporary fixation at point C, as shown in FIG.

[0020] The worker hooks the hooking portion 14 of the cable hanger 10 onto the cable 50 between points C and E. As shown in Fig. 2, when the hooking portion 14 hooks onto the cable 50, the cable 50 comes into contact with the rotating portion 16. The cable 50 hooked by the hooking portion 14 is pulled in the direction of the arrow, that is, towards point D, and temporarily fixed at point D (see Fig. 3C).

[0021] Next, the worker hooks the hooking portion 14 of the cable hanger 10 onto the cable 50 between points A and C, and pulls the cable 50 hooked by the hooking portion 14 in the direction of point B, and secures it at point B. The worker temporarily secures the cable 50 at point B, thereby wiring the cable 50 between points A and E (see FIG. 3B).

[0022] In this procedure, when the cable 50 hooked by the hooking portion 14 is pulled in the direction of point D or point B, the cable 50 is pulled as the rotating portion 16 rotates because the cable 50 is in contact with the rotating portion 16. This allows the worker to easily pull the cable 50 under tension toward points D and C. Furthermore, since the rotating portion 16 moves on the cable 50 while rotating, it is easy to adjust the position of the hooking portion 14, and the cable 50 is less likely to be pulled in more than necessary.

[0023] The cable hanger 10 is a cable hanger 10 for attaching a cable 50, and comprises a rod-shaped operating handle portion 12 and a linear hook portion 14 provided at the end of the operating handle portion 12, the hook portion 14 having an arc-shaped portion 18 that opens toward the operating handle portion 12 side, and a rotatable cylindrical rotating portion 16 is journaled on the arc-shaped portion 18, and the rotating portion 16 is rotated by the cable 50.

[0024] The cable hanger 10 can prevent damage to the cable 50 during wiring work and can also improve the efficiency of zigzag wiring work.

[0025] In the cable hanger 10, the rotating portion 16 expands in diameter from the center in the longitudinal direction toward each end of the rotating portion 16.

[0026] The rotating portion 16 expands from the longitudinal center toward each end of the rotating portion 16, thereby enabling a secure grip on the cable 50.

[0027] In the cable hanger 10, the hook portion 14 is detachable from the operating handle portion 12.

[0028] The hook portion 14 is detachable from the operating handle portion 12, so that a hook portion used in another cable hanger can be used.

[0029] It should be noted that the present invention is not limited to the above-described embodiment, and various configurations can be adopted without departing from the gist of the present invention.

[0030] In the above-described embodiment, the operating handle 12 is made of stainless steel, but the material of the operating handle 12 is not particularly limited as long as the operator can grip it and perform the work. For example, the operating handle 12 can be made of carbon, glass fiber, etc.

[0031] The operating handle 12 is extendable, and the means for extension is not particularly limited. For example, it may be a telescopic type, a foldable type, an add-on type, or the like. [Explanation of symbols]
