DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in the construction of a wiring tool, particularly a wiring tool used for passing various wires such as electric cords under the floor or under the ceiling.

[0002]

2. Description of the Related Art Conventionally, when a plurality of electric wires and the like are passed under the floor, behind a ceiling, or in a predetermined pipe, it is difficult to pass such electric wires or the like directly through a narrow space because the wires are clogged or bent on the way. Since the operation is extremely difficult, the wire is passed through these wires using a tool.

[0003] As such a conventional wire tool, there is a piano wire having a certain degree of hardness. In particular, when passing through a long distance, a piano wire having a large thickness is used, and in the wire-passing work, first, a piano wire as a wire-through tool is inserted into a space to be routed. Then, a wire to be passed is attached to any one end of the piano wire, and the wire is pulled out to the other end side, that is, the tip side or the tail end side where the piano wire is inserted, so that the wire is passed through the space. I have. Alternatively, a wire is attached to a piano wire, a wire to be passed is attached to the wire once passed, and the wire is pulled back to the other end.

[0004] As other wiring tools, tools made of relatively hard plastics or metal wires coated with vinyl are used. Is the same as

[0005] In recent years, with the rapid progress of office automation, various types of OA equipment have been installed indoors, and in such buildings called intelligent buildings, many traffic lines are expected. It is designed in such a way that a large wiring space is secured, and the wiring work is relatively easy. However, it is very difficult to pass wires through the floor of a building having a conventional structure or under the ceiling for wiring.

For example, in the narrowest range, it is necessary to provide a plurality of wires under the floor with a gap of 2 cm above and below. Therefore, a tool such as the above-mentioned conventional plastic-adhered tool or a coated metal wire is easily bent during the wire passing operation, and when there is an existing wire, it is located above or below the wire. It is very difficult to pass through the gap. In the case of piano wire, depending on its thickness, it has a considerably high strength, and it is possible to perform wiring work even in a narrow range, but it is easy to damage existing wires, and when using thick objects, It is very difficult to perform the winding operation after the completion, and a troublesome operation is required. That is, there is a problem that the winding operation cannot be performed unless a plurality of operators are used.

In order to solve such problems, the applicant of the present application has proposed a wiring tool mainly composed of a tape-shaped member having a predetermined rigidity (referred to as a tape-shaped lead wire in the specification of the present application). (JP-A-7-274334).

[0008]

However, this tape-shaped wire tool achieves easy wire movement by making it possible to move smoothly in a narrow space.
It has a certain rigidity to ensure stability when moving in the space, so if it is a long wire tool corresponding to a relatively long distance, it will be necessary to handle it. Requires skill. In other words, it is necessary to hold the tape-shaped lead wire in a wound state because it is long, and when the holding state is released, the tape-shaped lead wire expands vigorously due to the rigidity, so that it is compactly wound. There is a situation that a casing for maintaining the rolled state is necessary, and it must be usable in the wound state.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wiring tool capable of facilitating a wiring operation using a tape-shaped wiring member.

That is, it is possible to keep the state fixed by the last turn. In addition, the operation of pulling out or rewinding the tape-like lead wire from the storage case can be performed smoothly because the tape-like lead wire in the laminated and wound state is rotatable and slidable in the storage case. it can.

According to a second aspect of the present invention, in the wiring tool, a width restriction for preventing collapse of a laminated state of a tape-like lead wire laminated and wound around a portion of a predetermined length from at least two opening ends of the storage case. Forming part. That is, if the laminated state of the tape-shaped lead wires in the storage case is broken by an impact or the like, the tape-shaped lead wires cannot be unwound by the pulling-out operation or the push-back operation from the opening. In order to achieve this, at least an opening end region has a width (narrow width) for preventing collapse of the laminated state.

It is not necessary to limit the pre-formed portion to only the region near the opening end, and the entire storage case may have an internal structure having such a width.

In the third aspect of the present invention, in order to make it easier to rewind the tape-like lead wire into the storage case, a rotary shaft core is provided in the storage case. Is provided with a handle portion for rotating the rotary shaft core from outside. And, by winding the tape-shaped lead wire around the rotation shaft core from the tail end side, when pulling out, it is possible to easily pull out from the entrance by holding the tip end side of the tape-shaped lead wire, When rewinding, it is possible to easily rewind and store by turning the handle.

According to a fourth aspect of the present invention, there is provided a wiring tool according to the third aspect, wherein the width in the thickness direction of the internal space of the storage case for the wiring tool according to the third aspect is such that the same lamination state of the tape-like lead wires is broken. There is no width. Therefore, it is possible to effectively prevent the stacked state of the tape-shaped lead wires from being collapsed in the casing due to an impact during transportation of the wire-feeding tool and the drawing-out or rewinding of the wire-shaped lead wires becomes impossible.

According to a fifth aspect of the present invention, since the luminous body locking portion for attaching and detaching a predetermined luminous body is provided at the locking portion provided at the tip end of the tape-shaped lead wire, it is commercially available. The predetermined light-emitting body can be locked and mounted by a simple operation, and it is possible to more easily perform a wiring operation in an under-floor part without lighting.

According to a sixth aspect of the present invention, the ring-shaped member is swingably attached to the locking portion at the tip of the tape-shaped lead wire.
First, a nominal wire that is not an electrical cable for the purpose of passing is once sent to the opposite side by a pushing operation using a tape-like lead wire, and an electrical cable or the like is attached to this lead wire, and the lead wire is pulled back, so that the electrical cable is passed through. Although the wire is used, the nominal wire can be easily and securely attached to the ring-shaped member, thereby facilitating the wiring operation.

According to a seventh aspect of the present invention, the tape-shaped lead wire has a curved cross section in a direction perpendicular to a longitudinal direction of the tape-shaped lead wire. For example, it has a curved shape or a bent shape. Therefore, deformation due to a force from a direction perpendicular to the longitudinal direction can be further suppressed. That is,
The maintenance of the stretched state is improved, and it is possible to effectively prevent the tape-shaped lead wire from being bent (wavy) at the time of the wiring operation.

As shown in FIG. 2, the lead wire 20 has a locking portion 22 at its tip. The lead wire 20 is formed of a steel material having a predetermined rigidity, and the surface thereof may be covered with a resin material in some cases. For example, it is also possible to coat the surface of a steel material with vinyl chloride. Note that the width of the lead wire 20 is 8 to 14 mm,
The thickness is about 0.5 to 3 mm. The flat surface is provided with scales for length display at predetermined intervals.

The locking portion 22 has a side surface shape as shown in FIG. 3, and is pushed forward over obstacles such as other wiring cords at the curved surface portion 22a at the bottom. .

The lead wire 20 is fixed to the locking member 22 at the fastening members 24a and 24b of the locking member 22 shown in FIG. In addition, a ring member 26 is attached to the distal end of the locking member 22 so as to penetrate the through hole 28. The ring member 26 can be fitted and locked into a ring locking recess 30 formed on the upper surface of the locking member 22.

Further, on the upper surface of the locking member 22, there is formed a luminous body mounting groove 32 into which a luminous body (a commercially available luminous body utilizing chemical change) can be pushed and locked. FIG. 4 shows a state in which the ring member 26 is actually locked in the ring locking recess 30.

Next, an actual use of the wire passing tool according to the present embodiment will be described with reference to FIG. In this drawing, for example, a description is given of a case in which a wiring operation is performed in a wiring space on a floor having a double structure. First, the above-mentioned luminous body 31 is set in a luminous state and mounted in the luminous body mounting groove 32. Next, as shown in this figure, the lead wire 20 is inserted into the wiring space on the floor from the locking member 22 side, which is the distal end side, through the removed opening of the floor panel. At this time, the ring member 26 is locked in the ring locking recess 30 so as not to swing and hinder the progress.

Then, the pushing operation is continued until the leading end of the lead wire advances to the destination. At this time, since the light emitting body 31 emits light, the position can be confirmed by looking into the wiring space from the target location side, and the movement of the lead wire 20 to the target location can be performed more smoothly. . As shown in FIG. 5, the feed operation of the lead wire 20 is performed while the worker holds the storage case 10 in an upright state and gradually pulls out the lead wire 20 from the storage case 10. . The lead wires stacked and wound during the pull-out operation of the lead wire 20 are easily pulled out while sliding and rotating in the storage case 10.

At the stage when the locking member 22 at the tip of the lead wire 20 reaches the target position, the operation of attaching the nominal wire is performed.
FIG. 6 shows this operation state, in which the ring member 26 attached to the leading end of the locking member 22 is attached to the ring member 26 by connecting a nominal line 34 or the like. And lead wire 2
0 is slowly pulled back to the lead wire feed position shown in FIG. In this operation, the lead wire 20 is rewound while being pushed back into the storage case 10 simultaneously with the retraction. Therefore, when the retraction operation is completed, the lead wire 20 is pushed back into the storage case 10 and stored.

Then, an electric cord or the like to be wired is attached to the call line 34 attached to the lead wire and pulled back, and the call line is pulled back from the target portion side, and the desired wire operation is completed. In the present embodiment, in order to prevent a defective state of the pull-out and push-back operation of the lead wire 20 from occurring in the wiring operation according to the present embodiment, in the present embodiment, the storage case 0 is provided with a width regulating structure. .

That is, FIGS. 7A, 7B and 7C
As shown in FIG. 5, a width regulating portion 11 for regulating the width of the inside of the case slightly smaller is formed in a predetermined length range in the vicinity of the opening ends 10a and 10b formed in a part of the circular arc of the storage case 10. doing.

This operation will be described with reference to FIG. 8. In the case where the lead wires 20 housed in a stacked and wound state are displaced laterally due to vibration or the like during operation, the inner space of the housing case 10 is If the width is large, the lamination state may be broken, which may cause a state in which the lead wire 20 cannot be put in and out. Therefore, the width W1 is set to be larger than the width of the lead wire 20 but not to break the laminated state, and the narrow width portions are formed at both ends. For example, by setting the width W1 to a limit of 1.5 times the width of the lead wire 20, it is possible to prevent the lamination state from being broken while allowing a smooth rotational sliding operation.

It should be noted that such a width restricting portion 11 has its function by being formed only at both ends as in the present embodiment. Further, a plurality of portions or the entire storage case 10 is shown in FIG. It is also possible to adopt a shape in which the width is regulated as described above.

Next, FIG. 10 shows a second embodiment of the present invention. The feature of the present embodiment is that a configuration for making the winding of the lead wire 20 easier is provided.

That is, the storage case 40 is

That is, the width of the lead wire 20 in the direction orthogonal to the laminating direction and the width in the thickness direction of the case are regulated. A rotating core 42 rotatably mounted on the shaft is provided at a substantially central position, and the lead wire 20 is wound around the rotating core 42 from the tail end side. In this stacked and wound state, the width of the inner space side of the storage case 40 is formed to a restricted width that is slightly wider than the width of the lead wire 20. Therefore, it is effective that the stacked state is broken during the operation. Is prevented.

A lead wire insertion / reception port 44 is formed at a corner at the lower position in the installed state of the storage case 40. Further, in the present embodiment, the storage case 4
A self-standing stand 46 is attached to the housing 0, and the function of the self-standing stand 46 enables the storage case 40 to be erected vertically during operation. In the present embodiment, the self-standing stand 46 is formed of a pipe-shaped member, one end of which is fixed to one side surface of the storage case (not shown), and the storage case 40 falls down on both front and rear sides in the figure. It has a bent shape that protrudes so as not to have.

According to the wiring tool having the above structure, the lead wire 2
0 is pulled out from the inlet / outlet 44 and inserted into the wiring space under the floor.
Is located near the floor, so that the lead wire 2
It is very easy to insert zero. Further, since the insertion operation of the lead wire 20 does not need to be performed while the operator holds the storage case 40 and is always erected on the floor, the insertion operation of the lead wire 20 is very easy. It is.

When the operation of inserting the lead wire 20, that is, the operation of withdrawing the lead wire 20 from the storage case 40 is completed, and the next operation of pulling back the lead wire 20 is performed, the rotary core 4
