[0014] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. [First embodiment] 1 to 6 are diagrams for explaining a first embodiment of the present invention. As shown in Figure 1, the wiring pull-out device according to this embodiment is used in combination with a wiring device mounting frame 1 (hereinafter sometimes abbreviated as mounting frame 1) that is installed on a wall surface 100 inside a room, and a decorative plate 2 that covers the periphery of this mounting frame 1. The mounting frame 1 is preferably a mounting frame for a large rectangular interconnect wiring device specified by the Japanese Industrial Standards (JIS). By configuring it so that it can be used in combination with such a standardized mounting frame 1, excellent versatility can be ensured.

[0015] The decorative plate 2 is provided to cover the periphery of the mounting frame 1, and has the function of enhancing the decorativeness of the installation location of the wiring device. An opening 2a for arranging a boss surface is formed in the decorative plate 2, and a boss portion 24 of the wiring device attached to the mounting frame 1 is fitted into the opening 2a, so that the boss surface 24a of the wiring device is arranged in the opening 2a. The boss surface 24a of this wiring device blends in with the decorative plate 2, thereby enhancing the decorativeness.

[0016] The cable pull-out device according to this embodiment is a wiring device for pulling out a wiring cable 3 laid on the back side of a wall surface 100 into a room. A connection plug 3a is provided at the end of the wiring cable 3 for connecting the wiring cable 3 to an electrical appliance, information device, communication device, etc. Typically, the connection plug 3a has an outer shape larger than the cross-sectional area of ​​the wiring cable 3.

[0017] The cable pull-out device includes a device body 10, a cable guide 20, and an airtight member 30. The device body 10 is formed in the shape of a hollow rectangular tube, and has a rear body opening 11 on the rear side for introducing the wiring cable 3, and a front body opening 12 on the front side for inserting the cable guide 20. The fixture body 10 is preferably formed with external dimensions equivalent to one module of a large rectangular interconnection fixture. Mounting brackets 13 are provided at appropriate locations on the outer periphery of the fixture body 10, and the fixture body 10 is attached to the mounting frame 1 by engaging these mounting brackets 13 with the mounting portions of the mounting frame 1. The mounting structure to this mounting frame 1 is also standardized by the Japanese Industrial Standards. As shown in FIG. 2, the mounting frame 1 to which the fixture body 10 is attached is attached to a wall surface 100 using fasteners 1a.

[0018] The cable guide 20 is divided into first and second cable guide parts 21 and 22, and as shown in FIG. 3, these cable guide parts 21 and 22 are assembled together and then assembled into the device main body 10. 4(a) shows the state in which the cable guide 20 is incorporated into the fixture body 10. Specifically, the cable guide 20 is inserted into the front opening 12 of the fixture body 10 from the rear side, and the front surface of the cable guide 20 (a boss portion 24 described below) is exposed from the front opening 12 of the fixture body 10.

[0019] The cable guide 20 formed by combining the cable guide parts 21 and 22 is hollow inside, and has a holder rear opening 23 on the rear side for introducing the distribution cable 3. Furthermore, the front side of the cable guide 20 forms a boss portion 24, the front of which is a boss surface 24a. The operating portion of a wiring fixture is generally called a boss portion, and this boss portion is fitted into an opening 2a for placing the boss surface of the decorative plate 2, with the boss surface, which is the front of the boss portion, being placed in the opening. As with general wiring fixtures, the boss portion 24 of the cable guide 20 is also fitted into an opening 2a for placing the boss surface of the decorative plate 2, with the boss surface 24a, which is the front of the boss portion 24, being placed in the opening 2a. A cable insertion hole 25 for inserting the distribution cable 3 is formed in the center of the boss surface 24a of the cable guide 20.

[0020] The distribution cable 3 is arranged between the first and second cable guide components 21, 22, and when these cable guide components 21, 22 are combined, the distribution cable 3 is sandwiched between these cable guide components 21, 22.

[0021] Furthermore, an airtight member 30 is disposed in the recessed space (which becomes the hollow inside the cable guide 20) inside each of the cable guide components 21 and 22. The airtight member 30 is made of synthetic rubber or synthetic resin that is airtight and flexible. The opposing surfaces of the airtight members 30 arranged on each of the cable guide components 21, 22 are formed flat, and when the cable guide components 21, 22 are combined, the opposing surfaces come into surface contact. As a result, when no distribution cable 3 is placed between the first and second cable guide components 21, 22, the airtight members 30 close the space between the holder rear opening 23 of the cable guide 20 and the cable insertion hole 25.

[0022] The distribution cable 3 is arranged between the cable guide components 21, 22. When the distribution cable 3 is arranged between the cable guide components 21, 22 and the cable guide components 21, 22 are combined, the distribution cable 3 is held in a sandwiched state between the cable guide components 21, 22, as shown in FIG. 4(b). This prevents the distribution cable 3 from rattling within the cable guide 20. Even in this state, the gap between the holder rear opening 23 and the cable insertion hole 25 of the cable guide 20 is blocked by the distribution cable 3 and the airtight member 30, maintaining airtightness.

[0023] Next, a method for installing the cable pull-out device according to this embodiment on an indoor wall surface will be described. 1, the wiring cable 3 wired on the back side of the wall surface 100 is pulled out through the construction hole 101 in the mounting frame 1, and the connection plug 3a is inserted through the opening 23 on the back side of the fixture body 10 and inserted into the cavity. In the same way, the wiring cable 3 is also inserted through the opening in the mounting frame 1 and the opening in the decorative plate 2, and pulled out into the room.

[0024] Next, an appropriate position of the drawn-out distribution cable 3 is sandwiched between the first and second cable guide components 21, 22. An airtight member 30 is disposed inside each of the cable guide components 21, 22 in advance. By dividing the cable guide 20 into the first and second cable guide components 21, 22, the state in which the distribution cable 3 is inserted can be achieved without being affected by the size of the connection plug 3a provided at the tip of the distribution cable 3. In addition, the airtight member 30 provided inside the cable guide 20 can hold the distribution cable 3 without rattle, and also ensure airtightness inside the cable guide 20.

[0025] Next, the cable guide 20 holding the distribution cable 3 is inserted into the front opening 12 of the device body 10 and assembled. Thereafter, the fixture body 10 is attached to the mounting frame 1, and then the mounting frame 1 is fixed to the wall surface 100 using fasteners, and the decorative plate 2 is attached to the mounting frame 1.

[0026] 5(a), the boss portion 24 of the cable guide 20 is fitted into the boss surface arrangement opening 2a of the decorative plate 2, and the boss surface 24a, which is the front surface of the boss portion 24, is arranged in the opening 2a. This allows the boss surface 24a of the cable guide 20 to blend in with the decorative plate 2, resulting in a highly decorative appearance.

[0027] 5(b), the cable pull-out device according to this embodiment can be attached to the mounting frame 1 in advance in preparation for future pulling out of the wiring cable 3. Even in this state, the boss surface 24a of the cable guide 20 is integrated with the decorative plate 2, so a highly decorative appearance can be obtained. Furthermore, even in this state, the airtightness inside the cable guide 20 is ensured since the airtight member 30 is disposed inside the cable guide 20.
