Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring tool for passing lead wires prior to a cable wiring route when wiring various cables under a floor or in a ceiling space.

As a construction work to wire various cables under the floor or in the ceiling, first pass the long lead wire of the wiring tool through the wiring route, connect the cable to the tip of this lead wire, and pull the lead wire back to connect the cable. I have some wiring to do.

Various wire-shaped materials such as strip steel wires, piano wires, and wire cables are used as lead wire materials. Such lead wires have elasticity so that they can avoid obstacles when they are passed under the floor or in the ceiling. However, this elastic force makes it difficult to wind the lead wire.

That is, when a straight lead wire is wound in the case, the repulsive force directed to the outside of the case increases due to the elastic force of the lead wire itself. As a result, a phenomenon occurs in which the lead wire wound in the case is disturbed by this repulsive force.

For example, the "lead wire storage drawer" described in Patent Document 1 prevents the proximal end of the lead wire from protruding from the case due to repulsion during the winding operation. The base end of the lead wire is the end that is first wound around the annular guide member that is rotatably housed in the case. The end that remains in the gap becomes the tip of the lead wire.

After the leading end of the lead wire is pulled out from the opening of the case, the lead wire is wound up. During this winding operation, if the reel-shaped lead wire exposed from a part of the case is grasped by hand and rotated, the base end of the first wound lead wire will rebound and the opening of the case will open. The protruding phenomenon hindered the rotation operation. In the "lead wire storage drawer" of Patent Literature 1, by connecting the base ends of the lead wires to an annular guide member, such disturbance of the lead wires is eliminated.

In addition, in the "method for manufacturing a winding reel for wire passing wire" described in Patent Document 2, a case of an annular body using a pipe is divided into an outer and an inner case, and a lead wire is wound around the inner annular body. A case configured to

The case of this annular body has a structure in which a connector is provided on the outer annular body and the inner annular body is rotatably held by this connector. The proximal end portion of the lead wire is connected to the inside of the inner annular body held by the connector, and the lead wire is wound around the inner annular body when the inner annular body is rotated.

Utility Model Registration No. 2574018 JP-A-57-199409

In the case described in Patent Document 1, when the lead wire is wound, the reel-shaped lead wire exposed from a part of the case is grasped by hand and rotated, so the lead wire may be damaged by the skin of the hand or fingers. It was easy to get caught in the wire, and the winding operation was extremely dangerous.

Moreover, if there is a gap between the inside of the pipe-shaped case and the wound lead wire, the lead wire that repels inside the case is likely to become disordered, causing a phenomenon in which the lead wire spreads outward to fill the gap. . Therefore, when the lead wires housed in the case are put in and taken out many times, the lead wires spreading along the gap in the case gradually come into close contact with the inner wall, and this close contact causes a large resistance during operation.

On the other hand, the case described in Patent Literature 2 has a configuration in which the pipe is divided into an outer portion and an inner portion. Therefore, there is a wide gap between the lead wire wound on the inner annular body and the outer annular body, and the inner annular body on which the lead wire is wound has a semicircular shape that bisects the pipe. Therefore, there are also gaps on the left and right sides of the lead wire. Therefore, in this case, the lead wires are in a state of being extremely prone to repulsion so as to fill the gaps spreading around the lead wires. Therefore, if the wound lead wire is disturbed along the gap, the greatly swollen lead wire may come into contact with the outer ring-shaped body, making it extremely difficult to rotate the inner ring-shaped body.

Furthermore, both cases of Patent Document 1 and Patent Document 2 have a structure in which a lead wire that is wound up is drawn out to the outside with a wide opening, and a part of the lead wire that is wound up is exposed. That is, in Patent Document 1, a part of the outer side of the lead wire is exposed from a notch formed by cutting out a part of the case. Further, in Patent Document 2, not only is the outside of the lead wire wound around the inner ring-shaped body exposed at the pass-permitting portion obtained by notching a part of the outer ring-shaped body, but also the outer ring-shaped body and the inner ring-shaped body are separated from each other. The entire outside of the lead wire is exposed even between .

In this manner, at the exposed portion of the lead wire on the outer side of the reel, the lead wire is more likely to swell due to the elastic force that always rebounds outward. In addition, if the outlet is wide, the position of the leading end of the lead wire locked in the outlet is likely to move, which may induce disorder in the wound lead wire. And, if the lead wire of the exposed part spreads out to the outside of the case, it is no longer possible to operate it.

FIG. 4 is a side view showing an operation of pulling out a lead wire from the storage case of the present invention; FIG. 4 is a side view showing an operation of winding a lead wire around the storage case of the present invention;

The tool of the present invention is a wiring tool provided with a lead wire 1 to be passed through a wiring route of a cable and a ring-shaped storage case 2 for storing the lead wire 1 by winding it (see FIG. 1).

As the lead wire 1, various wire-shaped materials having elasticity, such as a strip steel wire, a piano wire, and a wire cable, are used. In particular, since the steel strip wire has excellent straightness and can be wound in layers, it becomes the lead wire 1 that is most difficult to be disturbed in the wound state (see FIG. 3).

The storage case 2 has a double structure consisting of an inner case 10 and an outer case 20 each formed of a ring-shaped cylindrical body (see FIG. 1). When the lead wire 1 stored in the storage case 2 is to be pulled out, the lead wire 1 protruding from the outer case 20 is pulled out and passed through the wiring route of the cable (see FIGS. 2 and 8).

The inner case 10 is a part that rotates inside the outer case 20, and the lead wire 1 is wound and stored in the inner case 10. - 特許庁Therefore, the base end of the lead wire 1 is fixed inside the inner case 10 (see FIG. 2). In the illustrated example, the lead wire 1 is fixed using a fixing bolt 30 passing through the inner case 10 from the base end portion. Therefore, since the lead wire is not exposed during the winding operation, the lead wire is always pulled from the inside, and the operation can be performed smoothly.

The inner case 10 is formed with an opening 11 that opens along the ring-shaped cylindrical outer ring (see FIG. 3). The lead wire 1 is wound around the inner case 10 through the opening 11 and pulled out.

Further, the inner case 10 is provided with a regulating portion 12 for regulating the position of the lead wire 1 (see FIG. 3). The regulating portion 12 regulates both sides of the lead wire 1 so that the lead wire 1 wound around the inner case 10 is collected at the center of the thickness of the inner case 10 . By providing the restricting portion 12 in the inner case 10 in this manner, the left and right sides of the wound lead wire 1 are restricted and the lead wire 1 can be prevented from being disturbed in the left and right directions. As a result, even if the lead wire 1 is put in and taken out many times, the wound lead wire 1 can be prevented from being disturbed.

The restricting portion 12 shown in the figure is formed to form a groove having an inverted U-shaped cross section surrounding both sides from the bottom side of the lead wire 1 wound around the inner case 10 . Further, in the illustrated example, a plurality of protrusions forming the restricting portion 12 are protruded at intervals inside the inner surface body 13 of the inner case 10 (see FIG. 6). When the pair of inner side members 13 are combined in a cylindrical shape, a plurality of grooves having an inverted U-shaped cross section are continuously formed at intervals by a plurality of restricting portions 12 (see FIG. 3).

The lead wire 1 shown in the figure is provided by a strip-shaped steel wire that can be accommodated in a groove that is formed to have an inverted U-shaped cross section by the restricting portion 12 (see FIG. 3). Since the lead wires 1 are sequentially stacked in the groove, it is possible to reliably prevent the stacked lead wires 1 from being displaced from side to side.

That is, by providing the lead wire 1 with a steel strip that is sequentially stacked within the restricting portion 12 , the lead wire 1 can be best accommodated within the restricting portion 12 . Therefore, the effect of preventing disturbance of the lead wires 1 in the restricting portion 12 is maximized, and stable operability remains unchanged even after long-term use.

On the other hand, the outer case 20 is an outer part that rotatably accommodates the inner case 10, and has an extraction hole 21 for drawing out the lead wire 1 in the inner case 10, which is opened in a part of the outer ring portion of the cylindrical body (Fig. 1). The lead wire 1 is drawn in and out from the inner case 10 through the drawing hole 21 of the outer case 20 (see FIG. 2).

The lead wire 1 can be retained in the lead hole 21 by forming the opening of the lead wire 21 as small as possible according to the thickness of the lead wire 1 . That is, if the lead-out hole 21 is wide and large, the position of the lead wire 1 locked in the lead-out hole 21 is likely to shift, and the wound lead wire 1 may bulge outward. However, by making the opening of the drawing hole 21 as small as possible, it becomes difficult for the lead wire 1 to wobble, and it is possible to prevent deformation of the wound lead wire 1 .

Furthermore, since the lead wire 1 is inserted through the hole 21 in a part of the cylindrical outer ring portion of the outer case 20, the tip of the wound lead wire 1 is pulled through the hole by its own elastic force. 21 is always in a locked state to prevent the leading end of the lead wire 1 from being disturbed. As a result, it is possible to prevent disturbance due to elastic force from the tip of the lead wire 1 to the lead wire 1 of the operation opening 22, so that extremely smooth operation can be maintained even after repeated use.

Further, the outer case 20 is formed with an opening 22 for operation through which a part of the inner case 10 is exposed (see FIG. 4) at a position different from the opening of the drawer hole 21 . A guard body 23 covering the opening 11 in the inner case 10 exposed from the operation opening 22 is provided along the outer ring portion of the outer case 20 (see FIG. 5). As a result, even if part of the inner case 10 is exposed from the operation opening 22, the lead wire 1 inside the inner case 10 is covered with the guard body 23 and is not exposed to the outside at all (Fig. 4).

The guard body 23 can reliably prevent the lead wire 1 inside the inner case 10 from repulsing and jumping out from the operation opening 22 .

In order to return the drawn lead wire 1 to the inner case 10, it is necessary to grab the side surface of the inner case 10 exposed from the operation opening 22 and pull back the lead wire 1 (see FIG. 9). At this time, since the lead wire 1 is not exposed at all, the conventional inconvenience of hurting the fingers with the lead wire 1 during this pulling-back operation is completely eliminated.

In this manner, the lead wire 1 can be operated without touching the lead wire 1 by grasping the side surface of the inner case 10 exposed from the operation opening 22 and pulling back the lead wire 1.例文帳に追加Therefore, the operation of inserting and removing the lead wire has become an extremely safe operation.

In the illustrated example, a rotating rail 14 is projected from the outer surface of the inner case 10, and the rotating rail 14 is brought into contact with the inner surface of the outer case 20 (see FIGS. 3 and 4). This rotating track 14 can reduce the friction surface between the inner case 10 and the outer case 20 . As a result, the load during the rotating operation of the inner case 10 is reduced, and the rotating operation of the inner case 10 can be lightened.

Both the inner case 10 and the outer case 20 that constitute the storage case 2 are formed by connecting left and right divided members along the outer ring portion of the ring (see FIG. 6). That is, the inner case 10 is formed by joining the inner side members 13 divided into left and right around the outer ring portion of the ring-shaped tubular body. The outer case 20 is also constructed by joining laterally divided outer side members 24 . Such a configuration facilitates not only the manufacturing process of the storage case 2 but also the assembly of the ring-shaped storage case 2 and is suitable for maintenance. In addition, as the means for connecting the divided members, for example, bolts and nuts may be used, and conventionally known connecting means may be selected.

The head 3 is a member provided at the tip of the lead wire 1 (see FIG. 7). The head 3 is mounted so as to easily avoid obstacles when the lead wire 1 is passed under the floor or in the ceiling. The illustrated head 3 is configured so that the shape of the tip portion changes in three stages. That is, the first shape in which the extension piece 3B and the re-extension piece 3C are superimposed on the head substrate 3A (see FIG. 7(a)). Next, the head substrate 3A has a second shape in which the extension piece 3B is developed to extend the entire length (see FIG. 1(b)). Further, a re-extended piece 3C is developed from the extended extension piece 3B to form the third shape with the longest overall length (see FIG. 1(C)). Visibility can also be improved by attaching a reflective sticker (not shown) or the like to an arbitrary portion of the head 3 . The shape, material, accessories, etc. of the head 3 can be arbitrarily changed.

When the lead wire 1 in the storage case 2 is pulled out, the lead wire 1 protruding from the outer case 20 is pulled out and passed through the wiring route of the cable (see FIG. 8). In order to pull back the lead wire 1 that has been pulled out, a stable winding operation can be performed by grasping and rotating the inner case 10 that is protruding outside (see FIG. 9).

In addition, the shape and the like of the present invention are not limited to the illustrated examples, and the design can be freely changed without changing the gist of the present invention.
