According to this jig, the jig can be brought into an office attic or the like from a small construction opening by reducing the entire size. The cable can be pulled or the cable at hand can be guided to an outlet formed in a place where it cannot be reached.

[0004]

However, in the above-mentioned conventional jig, since the length of the jig in the extended state is fixed, the distance over which the cable can be pulled or the like is naturally limited. For this reason, even when the distance slightly exceeds the distance, it may not be possible to draw the cable or the like, which often causes inconvenience.

Therefore, it is conceivable to provide a large number of cylindrical bodies so that the extended dimension becomes sufficiently long. However, in this case, the size and weight of the jig are increased. In addition, there is a problem that it is inconvenient to carry and handle the jig.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is a portable jig and a wiring jig and a wiring jig which are convenient to carry and handle and which can suitably improve the workability of installing a cable in an attic or the like. It is intended to provide an auxiliary tool for a jig.

In order to solve the above-mentioned problems, the present invention has a jig body and an auxiliary tool connected to the jig body, and the jig body is configured to be extendable and contractible in one axial direction. And
The distal end is provided with a locking means for locking the cable, and the rear end is provided with a connected portion of the auxiliary tool, while the auxiliary tool is formed of a plurality of cylindrical bodies arranged concentrically and expands and contracts in the axial direction. It is configured so as to be freely provided, and a connecting portion to the jig main body is provided on the cylindrical body constituting the distal end when extended, so that the connecting portion and the connected portion removably connect the jig main body and the auxiliary tool in the axial direction. (Claim 1).

According to this jig, usually only the jig body is used, and the cable installation work is performed within the range of expansion and contraction of the jig body. When an operation exceeding the extension range of the jig main body is required, the operation is performed by connecting an auxiliary tool to the jig main body. Thereby, the working range can be expanded by the extension of the auxiliary tool.

[0009] In particular, in the assisting device, if a connected portion capable of connecting another assisting device is provided on the tubular body constituting the rear end when extended (claim 2), the assisting device further includes an auxiliary tool. Can be connected, and it is possible to cope with work in a wider range.

An axial projection is provided on one side of the connecting portion and the connected portion, and a receiving portion is provided on the other side so that the projecting portion can be fitted (claim 3). If a female screw is provided on one side of the connected portion and a male screw which can be screwed on the other side is provided (claim 4), the jig body and the auxiliary tool are firmly connected with a relatively simple configuration. It is possible to do.

On the other hand, the present invention is configured so that it can be extended and contracted in one axis direction and is detachably mounted on a wiring jig having a locking means for locking a cable at a distal end thereof. It has a receiving portion that is constituted by a plurality of cylindrical bodies arranged and is extendable and contractible in the axial direction, and that allows the rear end of the wiring jig to be axially fitted into the cylindrical body that constitutes the front end when extended. (Claim 5).

According to this auxiliary tool, the working range can be expanded by an amount equivalent to the extension of the auxiliary tool, simply by attaching the auxiliary tool to the rear end of a commercially available wiring jig.

In particular, when the connecting member is detachably attached to the cylindrical body constituting the distal end at the time of extension, and the receiving member is provided on the connecting member (claim 6), the configuration of the auxiliary tool is common. It is possible to attach to wiring jigs having different sizes.

[0014]

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view showing an example of a wiring jig according to the present invention. As shown in FIG.
Is composed of a jig main body 12 and an auxiliary tool 14 connected thereto. FIG. 1 shows the jig main body 12 and the auxiliary tool 14 before connection.

The jig body 12 has a plurality of cylindrical bodies formed of a resin material and having different diameters, which are provided concentrically and are configured to be able to expand and contract in the axial direction (left and right directions in FIG. 1).
In the illustrated example, it is composed of eight cylindrical bodies 16a to 16h.

Each of the cylindrical bodies 16a to 16h has a tapered shape whose diameter becomes slightly smaller from the rear end side to the front end side (from right to left in FIG. 1). As for the body, the outer cylindrical body (for example, the cylindrical body 16
a) a cylindrical body (for example, cylindrical body 1) having an inside diameter
6b) It is formed to be slightly smaller than the outer diameter of the rear end. That is, the jig body 12 can be extended as shown in FIG. 2 by sequentially pulling out the inner cylindrical body from the outer cylindrical body toward the distal end. The rear end of the cylindrical body is fitted inside the front end of the outer cylindrical body, thereby preventing the inner cylindrical body from dropping off from the outer cylindrical body and the jig body 1.
2 is held in an extended state.

When the jig body 12 is in the extended state, the cylindrical body constituting the tip, that is, the innermost cylindrical body 16h,
A hook member 20 for locking a cable such as a power supply line is attached to a tip end of the hook member 20 via a fitting 18.

Further, when the jig body 12 is in the extended state, the cylindrical body constituting the rear end, that is, the outermost cylindrical body 16a
, The rear end opening is closed and the inner cylindrical bodies 16b to 16
A plug 22 for preventing the falling of h is inserted.
As shown in FIG. 1, a screw shaft 24 extending in the axial direction protrudes from the plug 22, and a cover 26 formed of, for example, a rubber material is detachably mounted on the screw shaft 24.

The auxiliary tool 14 is basically configured similarly to the jig body 12.

That is, the assisting tool 14 is also configured such that a plurality of cylindrical bodies formed of a resin material and having different diameters are provided concentrically and can expand and contract in the axial direction.
It is composed of a plurality of cylindrical bodies 30a to 30d. The shapes of the cylindrical bodies 30a to 30d and the relationship between the inner and outer cylindrical bodies are configured in the same manner as the respective cylindrical bodies 16a to 16h of the jig body 12, and the inner cylindrical bodies are sequentially shifted from the outer cylindrical body to the distal end. By pulling out to the side, the auxiliary tool 14 can be extended. Then, when the inner tubular body is pulled out to some extent, the rear end of the inner tubular body is fitted inside the front end of the outer tubular body, whereby the inner tubular body is separated from the outer tubular body. Is prevented, and the auxiliary tool 14 is held in the extended state.

A reinforcing member 32 is fitted into the cylindrical body constituting the distal end in the extended state of the auxiliary tool 14, that is, the innermost cylindrical body 30d, as shown in FIG. An axial screw hole 34 corresponding to the screw shaft 24 of the jig body 12 is formed. In the auxiliary tool 14, the innermost cylindrical body 30d has a diameter substantially equal to the diameter of the outermost cylindrical body 16a of the jig body 12,
Alternatively, it is formed so as to be appropriately larger than that.

In the extended state of the assisting tool 14, a plug 36 is fitted into the cylindrical body constituting the rear end, that is, the outermost cylindrical body 30a, thereby closing the rear end opening of the cylindrical body 30a. The tubular members 30b to 30d are prevented from falling off.

In order to use the wiring jig 10 configured as described above to install a cable such as a power supply line, for example, a small construction opening leading to the ceiling of an office or the like is opened, and this construction opening is opened. The jig main body 12 is brought into the space above the ceiling via. Then, the inner cylindrical body is sequentially pulled out, and the jig body 1
2 is extended as shown in FIG. 2, and a cable introduced into the back of the ceiling at a distant place is hooked by the hook member 20 at the tip of the jig main body 12 so as to be pulled closer to the hand, or the cable at hand is After being entangled with the hook portion 20, the jig main body 12 is extended, and the cable is guided to an outlet formed at a remote location. This allows the cable installation work to be quickly performed in a narrow place such as behind the ceiling.

If the position of the cable to be drawn or the outlet of the cable is too far to be handled by the jig body 12, the work is performed by connecting the jig body 12 to the auxiliary tool 14. Specifically, as shown in FIG. 3, the cover 26 is removed from the jig body 12 and the screw shaft 24 is removed.
Is screwed into and inserted into the screw hole 34 of the auxiliary tool 14 to connect the auxiliary tool 14 to the rear end of the jig body 12.
Is in the extended state. In this way, the cable installation work can be performed while expanding the work range by the length of the auxiliary tool 14.

According to the wiring jig 10 as described above,
Normally, by using only the jig body 12, it is possible to carry out work without complicating carrying and handling, and when the jig body 12 alone cannot cope,
The work can be performed while the work range is enlarged by attaching the auxiliary tool 14. In addition, since the auxiliary tool 14 is configured to be expandable and contractable similarly to the jig main body 12 as described above, the auxiliary tool 14 can be easily carried in a reduced state when not in use, and can be easily used through a small opening when used. It can be easily brought into the ceiling or the like. Therefore, according to the wiring jig 10, since the installation work can be performed in a wider range, it is easy to carry and handle, and the workability of this kind of cable installation work is effectively improved. be able to.

By the way, in order to be able to work in a wider range, for example, it is conceivable to construct a wiring jig in which an extremely large number of cylindrical bodies are integrally provided so as to be able to expand and contract. However, in this case, the jig becomes large and the weight increases, which is disadvantageous in terms of carrying and handling, and on the contrary, the workability may be reduced. On the other hand, in the wiring jig 10, as described above, the jig main body 1 is usually used.
If only the jig body 12 is used and only the jig main body 12 cannot cope with it and the work is carried out with the auxiliary jig 14 attached, the workability may be reduced like the above-mentioned wiring jig. Absent.

The wiring jig 10 is an example of the wiring jig of the present invention, and its specific configuration can be appropriately changed without departing from the gist of the present invention.

For example, as shown in FIG.
Instead of the plug 36 of FIG. 4, the auxiliary tool 14 provided with a plug 38 having a screw shaft 40 projecting from the screw hole 34 may be provided. In the figure, reference numeral 42 denotes a cover made of a rubber material or the like, which is detachably attached to the screw shaft 40. According to the auxiliary tool 14 shown in this figure, the cover 42 is removed, and the auxiliary tool 1 is further attached to the rear end of the auxiliary tool 14 via the screw shaft 40.
4 can be connected, so that the range of cable installation work can be further expanded.

The structure of the connecting portion between the jig body 12 and the auxiliary tool 14 is not limited to the connecting structure of the wiring jig 10, but the following connecting structure can be adopted.

For example, as shown in FIG. 5 (a), a plug 22 having a columnar projection 44 projecting therefrom and having an axial screw hole 46 formed thereon is mounted on the jig main body 12, while a cross section is formed. A reinforcing member 32 having a circular recess 48 formed therein and having an axial screw shaft 50 protruding therein is attached to the assisting tool 14, and FIG.
As shown in (b), the screw shaft 50 is screwed into the screw hole 46,
The connecting portion structure may be configured such that the projection 44 is inserted into the recess 48 while being inserted. According to such a connecting portion structure, the bending rigidity at the connecting portion between the jig body 12 and the auxiliary tool 14 can be effectively increased.

As shown in FIG. 6 (a), a plug 22 having a columnar shape 52 is mounted on the jig body 12, and a reinforcing member 32 having a concave section 56 having a circular cross section is used as an auxiliary tool. 14, and the projection 52 is fitted into the recess 56 as shown in FIG. 6B, and then orthogonal to the axial direction formed on the projection 52 through the through hole 58 formed in the reinforcing member 32. The jig body 12 and the auxiliary tool 14 may be connected by screwing a thumbscrew 60 into the screw hole 54 in the direction in which the jig body 12 is to be connected. In the case of this example, besides fastening the jig body 12 and the auxiliary tool 14 using the thumb screw 60, as the simplest means, a tape is wound around the contact portion between the plug 22 and the reinforcing member 32. Alternatively, the jig body 12 and the auxiliary tool 14 may be connected.

In the examples shown in FIGS. 1 to 6, the connecting portion structure is provided on both the jig body 12 and the auxiliary tool 14 to connect the jig main body 12 and the auxiliary tool 14. The jig body 12 and the auxiliary tool 14 can also be connected using the following connection tools.

For example, as shown in FIG. 7A, concave portions 66 and 68 are formed on both sides in the axial direction of a cylindrical body made of a hard rubber material.
As shown in FIG. 7B, the tip of the auxiliary tool 14, that is, the tip of the cylindrical body 30 d is pressed into the recess 66 on one side, and the recess on the other side is formed as shown in FIG. The rear end of the jig main body 12, that is, the rear end of the cylindrical body 16 a may be press-fitted into 68, thereby connecting the jig main body 12 and the auxiliary tool 14 via the connecting tool 64. In the figure, reference numeral 23 denotes a plug attached to the rear end of the cylindrical body 16a.

In this way, although the connecting tool 64 is required, the structure of the jig body 12 and the auxiliary tool 14 is simplified because the connecting structure such as screws is not required for the jig body 12 and the auxiliary tool 14. There is an advantage that can be made. In addition, since the connecting structure is not required on the jig body 12, there is an advantage that the auxiliary tool 14 can be attached to a commercially available wiring jig having the same configuration as the jig body 12, for example. . In this case, in particular, by forming the concave portion 68 according to the size of the wiring jig, the common auxiliary tool 14 can be mounted on the wiring jig of a plurality of sizes.

As the connecting member 64, in addition to those shown in FIG. 7, for example, as shown in FIG.
The jig body 12 and the auxiliary tool 14 may be firmly connected by increasing the insertion force of the jig body 12 and the auxiliary tool 14 into the connecting tool 64 by appropriately forming irregularities therein. Further, as shown in FIG. 9, a screw hole 70 is provided in the connecting tool 64, a screw is screwed on the surface of the cylindrical body 30d of the auxiliary tool 14, and the cylindrical body 30d is screwed into the screw hole 70 and inserted. The connecting tool 64 may be integrated with the auxiliary tool 14 in advance.
