DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable-wiring tool used when wiring cables such as electric wires and telephone wires by passing through the space above a ceiling, inside a wall, inside a pillar, etc. of an existing building. is there.

[0002]

2. Description of the Related Art Among conventional cable wiring tools of this kind,
The tool mainly used for wiring behind the ceiling is, as illustrated in FIG. 13, a telescopic rod 31 in which a hook fitting 32 for hooking and locking a cable is fixed to a distal end of a telescopic rod 31 via a fixing fitting 33. It has been known. The same concept is disclosed in, for example, Japanese Utility Model Publication No. 4-45376.

[0003] Wiring work using this type of telescopic rod 31
The extensible rod 31 is sequentially extended from the distal rod 31a so that the distal end of the rod faces the cable insertion port, and the distal end of the cable to be wired to the distal end hook 32 is connected. In this case, the rod 31 is sequentially shortened from the base rod side by a retracting operation to shorten the rod, and the cable is drawn closer to the hand. Therefore, the work can be performed as long as the wiring work is performed in a space above the ceiling and in a horizontal plane. However, usually wiring work on the invisible part inside the building is done between the outer wall and the inner wall of the building, for example, between the outlet in the room installed near the floor and the ceiling, or between the wire entrance and the ceiling. There are many works performed in a narrow vertical space such as in a pillar or the like. In this case, the above-mentioned telescopic rod 31 cannot be applied directly. He was forced to reach the entrance and tie a cable to this rope to raise it, which was an inefficient task.

[0004]

Therefore, as described above, in the conventional wiring tool using the telescopic rod 31, the cable pulling rope cannot be extended to a narrow vertical space in the wall or pillar of the building. In the end, he could not avoid the difficulty of groping the rope down at the top of the vertical space. In addition, the rope dropped by groping must be captured at the cable entrance, and the rope is not necessarily caught by the reinforcing member or coupling member in the wall and reaches the cable entrance reliably. It is time-consuming and has a fundamental problem of extremely low work efficiency.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the fundamental problem that there is no wiring tool that is sufficiently satisfactory for performing wiring work efficiently as described above. Even in a narrow space, or in a small and small space inside a wall or a pillar, it is possible to perform cable wiring work easily and quickly without a great deal of labor. An object of the present invention is to provide a wiring tool that can be improved.

[0006]

The structure of the wiring tool according to the present invention for achieving the object will be described with reference to the reference numerals used in the embodiments. Guide 1 that can move smoothly in a narrow space such as
And a flexible member 2 that can be wound in a belt-like or linear shape whose one end b is directly or indirectly connected to the guide 1, and the guide is attached to one end 2 b of the flexible member 2. 1 and a support fitting 3 that contains and holds the flexible member 2 therein and has a distal end 3a that is smoothly bent, and one end of the flexible member 2. It is configured such that the extending direction on the 2b side is regulated by the support fitting 3, and the distal end of the support fitting 3 is disposed at the upper end in a narrow and small vertical space in a wall or a pillar and is long. Of the flexible member 2 and the cable stopper 4
Is moved to a cable insertion port such as an outlet mounting portion. At this time, even if the guide 1 encounters a reinforcing member or a coupling member between the wall surfaces existing in the vertical space, the guide 1 moves smoothly without being caught by these members and guides the distal end of the flexible member 2. be able to.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In implementing the wiring tool, the flexible member 2 is stored in a housing 5a of a flexible member housing 5 by storing a base end 2a and an intermediate portion 2c following the base 2a. A spline is wound around the rotatable center shaft 5b provided, and in use, the spline-wound intermediate side portion 2c is caused to retreat from the opening 5c of the housing 5a into the support fitting 3 so that the wiring tool is used. At the upper end of the vertical space inside the wall or column,
arranged as facing lower openings of a, the flexible member 2 of the intermediate exiting to the outside by changing its course downward along the support fitting 3
The side portion 2c is made to hang down using the weight of the guide 1,
This can be performed by causing the cable locking body 4 attached to the one end 2b of the flexible member 2 to reach a cable insertion port such as an outlet mounting portion.

The guide 1 for leading the flexible member 2
Is a pivot 1 attached to one end 2b of the flexible member 2.
The roller structure may be a roller structure in which a ring 1b is pivotally attached to both ends of a, or an object such as a spindle-shaped weight made of metal or the like.

The flexible member 2 may be a wire made of a fibrous material, such as a rope or a metal chain, or a band made of a hard metal such as a steel plate or a stainless steel plate. It is good. In the case of the former wire rod, since the material is flexible, even in a work space in which a large number of reinforcing members and coupling members are distributed between the walls as described above, the work can be guided by the guide 1 that hangs smoothly. The insertion of the flexible member 2 is extremely easy. On the other hand, in the case of the latter band material, the cross-sectional shape is arc-shaped in a state where no external force is applied, a wave-shaped or mountain-shaped, curled or annular shaped in advance,
It may be flat or unshaped and may have any shape. Such a strip has excellent self-repulsive force and is spline-wound inside the housing 5a. When it passes through the bent part of the support fitting 3 or the like, it becomes flat and deforms into a shape with a small volume according to the external force. However, once it is separated from the support fitting 3 and the external force disappears, it returns to the original sectional shape As a result, a rod having a certain degree of rigidity is obtained. Therefore, when the flexible member 2 is extended,
By using the pushing force of the flexible member 2 by operating the driving device provided on the housing 5a together with the gravity of the guide 1, the cable stopper 4 is inserted into the cable insertion port at the target position by operating the support fitting 3. May be relatively easy to reach. In the case of a belt-like shape, the surface of the flexible member 2 may be provided with a reading symbol or the like indicating the feeding length or the separation distance of the guide 1.

Since the present invention has such a configuration, the flexible member housing 5 attached to the support fitting 3 is kept at hand, and the intermediate portion 2c of the flexible member 2 is sequentially placed. By being extended, the guide 1 is moved toward the lower cable insertion port together with the weight of the guide 1 or the pushing force of the flexible member 2, and the distal end of the cable to be wired to the cable locking member 4 is engaged at the cable insertion port. After stopping or tying, the intermediate portion 2c of the flexible member 2 is sequentially wound up to draw the one end 2b of the flexible member 2 and draw the cable. Also, using a flexible member 2 as a band material and a roller 1 having a ring 1b as the guide 1, a cable to be wired to the cable locking member 4 at the hand position is connected. In this case, the cable can be conveyed and wired to a predetermined position, contrary to the above-mentioned operation, by positively extending the flexible member 2 from the housing 5a.

As described above, the cable wiring tool according to the present invention is made of a flexible member 2 such as a rope, a chain, or a thin metal band of about 0.1 to 0.5 mm which is relatively thin and has a high elasticity. By using the gravity of the guide 1 or by using the pushing force of the flexible member 2 together, the cable locking body 4 is moved up and down to draw or convey a required cable. Therefore, even in the case of wiring work in a narrow vertical gap such as between peripheral members such as walls or in a pillar, it is possible to extremely easily operate the wiring work, and to speed up and simplify the wiring work. In addition, since the flexible member 2 itself is lightweight and small in volume, the long flexible member 2 can be wrapped around. Therefore, there is an advantage that wiring in a range where the wiring distance is relatively long can be easily performed. is there.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 are views showing a first embodiment of the present invention, wherein FIG. 1 shows an external shape of a wiring tool of the present invention, FIG. 2 shows a cross-sectional structure of the wiring tool, FIG. 3 shows another sectional structure of the wiring tool, and FIG. 4 shows a usage example.

The wiring tool shown as the first embodiment has a guide 1 having a diameter of 40, as shown in FIGS.
輪 1 mm are connected to each other by two pivots 1a.
In addition, a flexible member 2 made of a long steel strip is attached to the pivot 1a at one end 2b. Further, a cable hook 4 in the form of a closed hook is suspended and connected to a U-shaped bracket 4a protruding from the outer peripheral surface of the pivot 1a. As means for attaching the flexible member 2 to the pivot 1a, one end 2 of the flexible member 2 in FIGS.
b is attached so as to be wound around the pivot 1a. The U-shaped bracket 4a may be fixed to the turning point of the flexible member 2 or may be fixed to the pivot 1a through the flexible member 2. Further, the one end b of the flexible member 2 and the U-shaped bracket 4a or the cable stopper 4 may be fixed to the pivot 1a with a screw. In short, the flexible member 2 and the ring members 1a, 1a may be fixed.
It is sufficient that the guide 1 is relatively rotated to smoothly move the guide 1 in a narrow space with many obstacles by gravity. Therefore, any means can be adopted. Flexible member 2 used in this embodiment
Is a steel strip having a width of 10 to 15 mm, a thickness of 0.2 to 0.3 mm, and a length of 20 m, and is shaped in advance so that its cross-sectional shape becomes an arc shape when external force is removed. Is the feeding length or the ring bodies 1b, 1b as shown in FIG.
A reading symbol 2d indicating the separation distance up to is provided.

As shown in FIGS. 1 and 2, most of the flexible member 2 is accommodated in a flexible member housing 5. That is, the flexible member housing 5 comprises a substantially sealed housing 5a and a center shaft 5b pivoted by a handle (not shown) at the center thereof, and has an opening 5c at one end. The base end 2a of the flexible member 2 is attached to the central shaft 5b.
And a large part following the base end 2a, that is, an intermediate part
2c is wound around the central axis 5b in a spline shape, and is protruded and retracted from one end through the opening 5c. In this case, the handle for driving the central shaft 5b has a free structure with respect to the central shaft 5b.
If the structure is such that the handle does not rotate even if the center shaft 5b rotates when the reels are pulled out, it is extremely convenient to carry out the work.
Alternatively, when the wiring tool is not used, if the handle is folded and the flexible member 2 is configured to be clamped to the housing 5a, the tool can be easily handled. The portion of the extended flexible member 2 that protrudes outward from the opening 5c protrudes in the form of a rod to remove external force when housed in the housing 5a. Reference numeral 5d in FIGS. 1 and 2 denotes a hanging rod of the flexible member housing 5.

A support fitting 3 for holding the flexible member 2 is attached directly to the outside of the opening 5c of the housing 5a. As shown in FIG. 1, the support fitting 3 is a rectangle with a part cut out, and is smoothly bent so that the tip 3a faces downward. The belt-shaped flexible member 2 is continuously fed out of the housing 5a, moves while being supported by the inside of the support fitting 3, is bent downward near the tip of the support fitting 3, and hangs downward in the space. go. In order to use the wiring tool having such a configuration, as shown in FIG. 4, for example, the wiring tool is placed on the ceiling plate 42 at the back of the ceiling D, and the distal end 3a of the support 3 is directed downward to the outer wall 40. The intermediate portion 2c of the flexible member 2 is sequentially extended toward the front while holding the portion of the housing 5a so as to project upwardly of the vertical space E where the wiring work is to be performed. The guide 1 hangs down in the vertical space E by its own weight,
Even if it encounters the reinforcing bar 43 or the connecting member 44 connecting the inner wall 41 and the outer wall 40 on the way, it passes through the ring 1a smoothly while avoiding it while rotating, and guides the flexible member 2 to the cable insertion port. After the distal end of the cable to be wired to the cable locking body 4 is locked or tied and connected at the cable insertion opening, the flexible member 2 is sequentially pulled to perform the cable drawing wiring.

FIG. 5 is a view showing a main part of a second embodiment. In this embodiment, the flexible member 2 is made of a flexible rope 2 made of a strong fibrous material such as polyimide. ´
The guide 1 uses a weight 1 'having a simple structure. A cable locking body 4 is attached to the tip of the rope 2 ′, and a ring-shaped hook 1 c is formed on the weight 1 ′. When the wiring tool is used, the hook 1 c is connected to the cable The guide 1 is hooked on the stopper 4.
After connecting and connecting the cable to the cable locking body 4,
When pulling the flexible member 2, the weight 1 ′ may be removed from the cable locking body 4 or may be left attached. The support fitting 3 in the present embodiment has a pipe-shaped cross section. Manufacturing using a pipe has a feature that the manufacturing cost of the support fitting 3 is reduced.

FIG. 6 is a view showing a first modification of the first and second embodiments. In this modification, the support fitting 3 is composed of telescopic members 3b, 3c,. It has a structure and is configured to be stretchable. By successively extending the support members 3b,..., It is very convenient when the work hole in the ceiling and the work space for arranging the cables are separated.

FIG. 7 is a view showing a modified example 2 of the first embodiment and the second embodiment, wherein a battery 6a and a light bulb 6b are provided above the guide 1 or the cable stopper 4 of each embodiment. Are provided with a lighting device 6 housed in a case 6c having a transparent portion 6d and having a required strength. The second modification has a feature that is extremely useful for catching the portion of the cable locking body 4 of the suspended flexible member 2 at the cable insertion port.

FIG. 8 is a view showing another embodiment of the flexible member housing 5 in the first embodiment. The driving roller 5e and the idle roller 5 are located inside the opening 5c of the housing 5a. And a small motor (both not shown) in which a drive roller 5e is provided outside the housing 5a or a rotary motor provided continuously outside the housing 5a. The flexible member 2 is extended by being rotated by rotation. When the central shaft 5b is rotated and the flexible member 2 is wound and accommodated, the idle roller 5f may be moved to release the pressure contact with the drive roller 5e as shown by the imaginary line. As a structure for pressing and releasing the idle roller 5f, the idle roller 5f may be supported by a lever, and the lever may be operated with a finger. Further, a structure for interlocking with the operation of either the handle for driving the central shaft 5b or the handle for driving the drive roller 5e (all of which are not shown) may be employed. The structure of the other parts is the same as that of the first embodiment, and the description is omitted. In this alternative embodiment, a cable to be laid at a hand position or a rope serving as a pilot is
When the flexible member 2 is extended and suspended as described above, and the cable is conveyed and wired to a predetermined position and used, the flexibility of the cable or the pilot rope is burdened only by the gravity of the guide 1. This is very effective when the feeding force of the flexible member 2 is insufficient.

FIGS. 9 to 12 show cross-sectional shapes of the strip used as the flexible member 2 of the first embodiment in the state where no external force is applied. FIG. 10 and below have been subjected to shaping beforehand, and those in FIG. 10 become corrugated when no external force is applied, and those in FIG. 11 Indicates a mountain shape, and FIG. 12 indicates a C-shaped curl. In this manner, the flexible member 2 can be used in any of preformed and unshaped ones. However, it is preferable that the flexible member 2 be given a deformable self-restoring force in advance, because the pressing force when the guide 1 is advanced when extended, that is, when the guide 1 is advanced.

The embodiments which are considered to be representative of the present invention have been described above. However, the present invention is not necessarily limited to the structures of the embodiments, but has the above-mentioned constitutional requirements according to the present invention, and The present invention achieves the object of the present invention and can be appropriately modified and implemented within the range having the following effects.

[0022]

As is apparent from the above description, the cable wiring tool according to the present invention comprises a guide 1 which can move smoothly in a gap between peripheral members such as walls, and a direct or indirect guide to the guide 1. And a long flexible member 2 that can be wound in a band shape or a linear shape and connected to the one end 2b side thereof, and a cable locking body provided together with the guide 1 on one end 2b side of the flexible member 2 4 and one end of the flexible member 2 including and holding the flexible member 2 therein and having a smoothly bent distal end portion 3a. Since the feeding direction on the b side and the feeding position downward are guided by the support fittings 3, the middle of the flexible member 2 is flexible.
The cable locking body 4 can be made to reach a target place such as a cable insertion port by simply operating the side portion 2c forward by the weight of the guide 1. The remarkable effect that the wiring work can be performed extremely easily even in a narrow place by being connected to the locking body and pulled or conveyed can be expected.

Further, since the flexible member used for moving the cable locking member according to the present invention is lightweight and small in volume, it can be easily moved and transported as a whole, and can be long. Since the flexible member can be involved, it is possible to expect an effect that wiring in a long range that cannot be reached with a rod can be easily performed.
