Description

The present invention relates to a cable tie tool that can remotely tie open-type cable ties, and to an installation method that can remotely tie cables from the floor side, for example when tying wiring cables placed on a support bracket at a high altitude to the support bracket.

Patent documents 1 and 2 describe tools and methods for using cable ties remotely to fasten wiring cables and other items placed on support brackets at high altitudes to the support brackets.

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 tightens it by inserting the band portion through the locking portion by operating the existing gripping tool.

The method described in Patent Document 2 uses two pliers-shaped tools, with the locking part held at the tip of one tool and the band part held at the tip of the other tool being manipulated to insert the band part into the locking part and tighten it.

On the other hand, Patent Document 3 describes an open-type cable tie. The basic structure of this cable tie is the same as that of a general cable tie, with a roughly square cylindrical locking section at the base end of the band section that ties together the members, and the engagement recess of the band section inserted into this locking section engages with the engagement protrusion of the locking section to tighten the cable tie.

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 this gripping portion. Furthermore, the locking portion has a slit-shaped opening that allows this thin introduction portion to 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.

Conventional tools and methods for fastening cable ties remotely all require the use of two tools: one to secure the locking section and one to operate the band section. As a result, the task of passing the band section of a cable tie located at a high place through the locking section by remote control from the floor and fastening it is an extremely difficult task, much like threading a needle.

On the other hand, open-type cable ties are known to be extremely easy to use because the cable tie is fastened when the gripping part is pulled after the introduction part is introduced into the locking part through an opening on the side of the locking part. Therefore, the inventors focused on this open-type cable tie in order to simplify the task of fastening cable ties at high altitudes using remote control.

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, making it extremely easy to use a single tool to tie cable ties at high altitudes.

The mounting tool of the present invention is a tool that remotely ties a wiring cable P, etc., that is hung on a support bracket Q, etc. at a high altitude, to the support bracket Q, etc.

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, with a locking portion S2 that engages and fixes the band portion S1 at the base end side of the band portion S1 that tightens the members. Furthermore, as a unique configuration, the tip side of the band portion S1 has a gripping portion S5 and an introduction portion S4, 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 Figure 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 this band portion S1 engages into the locking portion S2.

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

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

The lock retaining portion 11 is a portion that retains the locking portion S2 of the cable tie S, and in the illustrated example, comprises a retaining portion 11A and an opening introduction portion 11B (see FIG. 3). The retaining portion 11A is a generally rectangular tube that retains the outside of the locking portion S2, and the opening introduction portion 11B is a slit that overlaps with the opening S3 of the locking portion S2 retained by the retaining portion 11A.

The band holder 12 is a part that is continuous with the lock holder 11 and is freely swingable. It is configured to hold the tip side of the band part S1 and introduce the introduction part S4 from the opening S3 into the lock part S2.

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 a clamping portion 12C. The swinging arm 12B is connected to the tip of the fixed arm 12A so that it can swing freely, and holds the tip of the band S1 with two clamping portions 12C. The swinging arm 12B is configured to hold the band S1 with the introduction portion S4 and gripping portion S5 of the cable tie S protruding from the tip of the swinging arm 12B. The lock S2 may also be held by the band holder 12 or the like.

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 fully open state, and (B) shows the swinging arm 12B in its closed state.

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 that is slidably attached to the fixed arm 12A, and an operating 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 attached to the swing end side of the swing arm 12B (see FIG. 5 (b)). Furthermore, the pressing part 14 is slid upward to swing the swing arm 12B until it closes (see FIG. 6).

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 part 14 (see FIG. 5 (b)).

When the operating pole 30 is further raised, the abutment 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)).

Therefore, to tie 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 Figure 7). When the operating pole 30 is further pushed up from that state, the swinging arm 12B closes (see Figures 8 and 9), and the introduction portion S4 is introduced into the lock portion S2 of the cable tie S (see Figure 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).

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).

The illustrated band tip holder 13 is adjacent to the lower side of the lock holder 11 and has 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 engages, and is provided so that when the introduction portion S4 is introduced into the introduction groove 13A, the gripping portion S5 finally engages with 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).

Next, the movement of the gripping portion S5 of the cable tie S until it engages with the locking portion 13B of the band tip holder 13 and moves will be described. Figure 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 Figure 10).

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 Figure 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 locking holding part 11 (see Figure 11).

The process of tightening the cable tie S will be further explained 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 closed all the way, 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 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)).

The process of removing the tool body 10 after tightening the cable tie S is shown in Figures 14 to 16. First, after tightening the cable tie S 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 Figure 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, causing the swing arm 12B to open (see Figure 15). In other words, this swing arm 12B is designed to be opened and closed by the fingers (see Figure 4).

Therefore, when the swinging arm 12B is hooked onto the support bracket Q and the operating pole 30 is pulled down, the swinging arm 12B easily opens. When the operating pole 30 is lowered at this time, the pressing part 14 fixed to the operating pole 30 goes down first, followed by the fixed arm 12A, which opens the swinging 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 operating pole 30 is removed from the support bracket Q, and the work is completed (see FIG. 16).

The installation method of the present invention is an installation method that uses the above-mentioned tool body 10 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 that holds the tip end 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 gripping 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.

The embodiments of the present invention are not limited to the illustrated examples, and design changes are free to the extent that they do not change the gist of the present invention. For example, it does not have to be an open type.
