Description

[Technical field]

[0001] The present invention relates to a cable tie tool that remotely ties open-type cable ties, and more particularly to a cable tie tool and installation method that can be remotely operated from the floor when, for example, tying a wiring cable or the like placed on a support bracket at a high altitude to the support bracket. [Background technology]

[0002] Patent documents 1 and 2 describe tools and methods for remotely tying cable ties when tying and securing wiring cables, etc., placed on a support bracket at a high altitude to the support bracket.

[0003] The tool described in Patent Document 1 fixes the locking portion of a cable tie to the tool body and grips the band portion of the cable tie with an existing gripping tool, and operates the existing gripping tool to insert the band portion through the locking portion to tighten it.

[0004] The method described in Patent Document 2 uses two pliers-shaped tools, in which a locking portion is held at the tip of one of the tools, and a band portion held at the tip of the other tool is manipulated to insert the band portion into the locking portion and tighten it.

[0005] Meanwhile, Patent Document 3 describes an open-type cable tie. The basic configuration of this cable tie is the same as that of a general cable tie, with a roughly square tubular locking part at the base end of the band part that ties together the members, and an engagement recess of the band part inserted into this locking part engages with an engagement protrusion of the locking part to tighten the cable tie.

[0006] In particular, this open-type cable tie has a gripping portion at the tip of the band portion, and an introduction portion that is thinner than the band portion is connected to the gripping portion. Furthermore, the locking portion has a slit-shaped opening through which the thin introduction portion can be introduced into the inside from the side of the locking portion. When the introduction portion is introduced into the locking portion from the opening and the gripping portion at the tip of the band portion is pulled, the band portion is drawn into the locking portion and engages with the inside of the locking portion.

[0007] [Patent Document 1] Patent No. 5295323 [Patent Document 2] Patent No. 6481444 [Patent Document 3] JP 2013-104552 A Summary of the Invention [Problem to be solved by the invention]

[0008] Conventional tools and methods for fastening cable ties remotely all require the use of two tools: one to secure the locking part and one to operate the banding part. Therefore, the task of passing the banding part of a cable tie located at a high place through the locking part by remote control from the floor side to fasten it is an extremely difficult task, like threading a needle.

[0009] On the other hand, an open-type cable tie is known to be extremely easy to use because the cable tie is tied by pulling the grip after the lead-in part is introduced into the lock part through an opening on the side of the lock part. Therefore, the inventor focused on this open-type cable tie in order to simplify the task of remotely tying cable ties at high altitudes.

[0010] The present invention was created to solve the problems of the past, and aims to provide a cable tie tool and installation method that uses an open-type cable tie to make it extremely easy to use a single tool to tie cable ties at high altitudes. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The mounting tool of the present invention is a tool for binding, for example, a distribution cable P hung on a support bracket Q at a high place to the support bracket Q by remote control.

[0024] The cable tie S used in the present invention is particularly an open type cable tie S. This type of cable tie S has a structure similar to that of a general cable tie, in which a locking portion S2 that engages and fixes the band portion S1 is provided at the base end side of the band portion S1 that tightens the members. Furthermore, as a unique configuration, a gripping portion S5 and an introduction portion S4 are provided at the tip side of the band portion S1, and an opening S3 for introducing the introduction portion S4 into the locking portion S2 is formed on the side of the locking portion S2 (see FIG. 18). Then, when the introduction portion S4 is introduced into the opening S3 and the gripping portion S5 is pulled, the band portion S1 is drawn into the locking portion S2, and the band portion S1 engages into the locking portion S2.

[0025] In order to tie such an open-type cable tie S by remote control, the tool body 10 of the present invention is attached, for example, to the tip side of an operation pole 30, and the tool body 10 is remotely controlled by operating an operation rope 20 connected to the tool body 10 (see FIG. 1). In the illustrated example, the operation rope 20 is wound around an operation ring body 40, and an engaging slide body 41 provided on the operation ring body 40 is slidably attached to the side of the operation pole 30 (see FIG. 2). The tool body 10 is remotely controlled by operating this operation ring body 40 (see FIG. 1).

[0026] The tool body 10 of the present invention includes a lock holder 11, a band holder 12, and a band tip holder 13.

[0027] The lock retaining portion 11 is a portion that retains the lock portion S2 of the cable tie S, and in the illustrated example, includes a retaining portion 11A and an opening introduction portion 11B (see FIG. 3). The retaining portion 11A is substantially in the shape of a square tube that retains the outside of the lock portion S2, and the opening introduction portion 11B is in the shape of a slit that overlaps with the opening S3 of the lock portion S2 retained by the retaining portion 11A.

[0028] The band holder 12 is a portion that is provided continuously from the lock holder 11 and can freely swing, and is configured to hold the tip end side of the band portion S1 and introduce the introduction portion S4 into the lock portion S2 from the opening S3.

[0029] The illustrated band holder 12 includes a fixed arm 12A and a swinging arm 12B (see FIG. 3). The fixed arm 12A is adjacent to the lock holder 11 and holds the side of the band S1 close to the lock S2 of the cable tie S with the clamping portion 12C. Meanwhile, the swinging arm 12B is connected to the tip of the fixed arm 12A so as to be freely swingable, and holds the tip side of the band S1 with the two clamping portions 12C. The swinging arm 12B is configured to hold the band S1 with the introduction portion S4 and the gripping portion S5 of the cable tie S protruding from the tip of the swinging arm 12B. Alternatively, the lock S2 may be held by the band holder 12 or the like.

[0030] The swinging arm 12B, which is swingably connected to the tip of the fixed arm 12A, can be opened and closed with the fingers (see FIG. 4). In the figure, (A) shows the swinging arm 12B in its maximum open state, and (B) shows the swinging arm 12B in its closed state.

[0031] In order to swing the swing arm 12B by remote control, a pressing part 14 is used in the illustrated example (see FIG. 5). The pressing part 14 is a member slidably provided on the fixed arm 12A, and an operation pole 30 is fixed to the pressing part 14 (see FIG. 5(A)). The swing arm 12B is then opened, and the abutment end 14A of the pressing part 14 is brought into contact with the abutment end 12Ba provided on the swing end side of the swing arm 12B (see FIG. 5(B)). Furthermore, by sliding the pressing part 14 upward, the swing arm 12B is swung until it closes (see FIG. 6).

[0032] At this time, with the swinging arm 12B open, the upper side of the fixed arm 12A is pressed against the lower side of the support bracket Q (see FIG. 5(a)). In this state, when the operating pole 30 is pushed up, the fixed arm 12A remains fixed to the support bracket Q, and only the swinging arm 12B is pushed up by the pressing portion 14 (see FIG. 5(b)).

[0033] When the operating pole 30 is further raised, the abutting end 12Ba swings (see FIG. 6(a)). Then, when the pressing portion 14 is pushed all the way up, the swinging arm portion 12B closes and the introduction portion S4 of the cable tie S is introduced into the lock portion S2 of the cable tie S held by the lock holding portion 11 (see FIG. 6(b)).

[0034] Therefore, to bind the wiring cable P to the support bracket Q, the cable tie S side of the fixed arm 12A is pressed against the underside of the support bracket Q on which the wiring cable P is placed (see FIG. 7). When the operating pole 30 is further pushed up from that state, the swinging arm 12B closes (see FIGS. 8 and 9), and the introduction portion S4 is introduced into the lock portion S2 of the cable tie S (see FIG. 10). Note that the pressing portion 14 is one example of a means for swinging the swinging arm 12B, and it can be changed to any other means, such as connecting a string or the like to the swinging arm 12B to swing it (not shown).

[0035] The band tip holder 13 is provided so as to be movable from a position adjacent to the lock holder 11 (see FIG. 3). When the band portion S1 of the cable tie S is introduced into the lock portion S2, the gripping portion S5 of the cable tie S is engaged with the band tip holder 13 (see FIG. 10). When the gripping portion S5 engaged with the band tip holder 13 is moved together with the band tip holder 13, the introduction portion S4 in the lock portion S2 moves and the band portion S1 engages with the lock portion S2 (see FIG. 11). As a result, the wiring cable P on the support bracket Q is tightened by the cable tie S (see FIG. 17).

[0036] The illustrated band tip holder 13 is adjacent to the lower side of the lock holder 11 and includes an introduction groove 13A, a locking portion 13B, and a connecting portion 13C (see FIG. 3). The introduction groove 13A is adjacent to the opening introduction portion 11B of the lock holder 11, and is a groove-shaped opening for introducing the introduction portion S4 of the cable tie S. On the other hand, the locking portion 13B is a portion where the gripping portion S5 at the tip of the introduced introduction portion S4 is locked, and is provided so that when the introduction portion S4 is introduced into the introduction groove 13A, the gripping portion S5 is finally locked to the locking portion 13B. Furthermore, the connecting portion 13C is a portion where the operating rope 20 for remote operation is connected, and when the operating rope 20 is pulled, the band tip holder 13 moves along the slide rod 13D (see FIG. 12 and FIG. 13).

[0037] Next, a description will be given of the movement of the gripping portion S5 of the cable tie S until it is locked with the locking portion 13B of the band tip holder 13 and moves. Fig. 9 shows the state in which the swinging arm portion 12B is closed to introduce the introduction portion S4 of the cable tie S into the holding portion 11A of the lock holding portion 11. When the swinging arm portion 12B is further closed, the introduction portion S4 is introduced into the lock portion S2 held by the holding portion 11A, and at the same time, the introduction portion S4 of the cable tie S is introduced into the introduction groove portion 13A of the band tip holder 13 (see Fig. 10).

[0038] The introduction groove 13A of this band tip holder 13 is formed with a wide entrance and a narrow depth, and after the gripping part S5 is introduced, only the introduction part S4 is introduced into the gradually narrowing introduction groove 13A, and finally the gripping part S5 is locked by the locking part 13B (see FIG. 10). When the band tip holder 13 is moved in this state, the band part S1 is introduced into the locking part S2 held by the lock holding part 11 (see FIG. 11).

[0039] The process of tightening the cable tie S will be further described with reference to Figures 12 and 13. When the swing arm 12B is closed, the gripping portion S5 is introduced into the introduction groove portion 13A of the band tip holder 13 (see Figures 12(a) and 13(a)). When the swing arm 12B is further closed, the gripping portion S5 is engaged with the engagement portion 13B of the band tip holder 13, and the introduction portion S4 is introduced into the lock portion S2 in the lock holder 11 (see Figures 12(b) and 13(b)). When the band tip holder 13 is lowered, the band portion S1 and the gripping portion S5 of the cable tie S are also lowered, so that the band portion S1 is introduced into the lock portion S2 in the lock holder 11 and engages with the lock portion S2 (see Figures 12(c) and 13(c)).

[0040] 14 to 16 show the process of removing the tool body 10 after tightening the cable tie S. First, after the cable tie S is tightened by moving the band tip holder 13, the tool body 10 is swung back and forth or left and right while maintaining the tension at the time of tightening to further tighten the cable tie S (see FIG. 14). Next, the operating rope 20 is loosened and the inside of the swing arm 12B is placed against the side of the support bracket Q on which the wiring cable P is placed, and the operating pole 30 is lowered, whereby the swing arm 12B opens (see FIG. 15). In other words, the swing arm 12B is structured so that it can be opened and closed with a finger (see FIG. 4).

[0041] Therefore, when the swing arm 12B is hung on the support bracket Q and the operation pole 30 is pulled down, the swing arm 12B easily opens. At this time, when the operation pole 30 is lowered, the pressing part 14 fixed to the operation pole 30 goes down first, and then the fixed arm 12A goes down, opening the swing arm 12B (see FIG. 15). Meanwhile, the cable tie S comes off the tool body 10 and the wiring cable P is tightened to the support bracket Q. Finally, the tool body 10 on the operation pole 30 is removed from the support bracket Q to finish the work (see FIG. 16).

[0042] The installation method of the present invention is an installation method in which the above-mentioned tool body 10 is used to remotely tie an open-type cable tie S. That is, the lock portion S2 of the cable tie S is held by the lock holding portion 11. Next, the band holding body 12 holding the tip side of the cable tie S is swung to introduce the introduction portion S4 into the opening S3 of the cable tie S held by the lock holding portion 11, and the grip portion S5 of the cable tie S is locked to the locking portion 13B adjacent to the lock holding portion 11. In this state, when the band tip holding body 13 is pulled down by remote control, the band portion S1 of the cable tie S engages with the locking portion S2.

[0043] The embodiments of the present invention are not limited to the illustrated examples, and the design may be freely changed within the scope of the present invention. For example, the present invention does not have to be of an open type. [Explanation of symbols]
