Abstract

PURPOSE:To facilitate the position adjustment and simplify the work by providing a case in the lower surface of which a slit for passing a wire is formed and which supports a slider in such a manner that the slider is slidable along the edge portion of the slit. CONSTITUTION:A case 2 is embedded in a ceiling frame 9 and takes the form of a box of trapezoid cross section capable of accomodating a wire 1 and a slit 3 for passing the wire 1 is formed in the lower surface of the case 2. A slider 5 is supported slidably along the edge portion of the slit 3 and both side plates are tilted as if reversely tapered so that they do not drop from the concrete of the frame 9 and mounting plates are projected from both end portions and a mounting hole is formed through the mounting plate. Therefore the slider 5 can be freely moved within the case 2 and position adjustment of the slider 5 is simplified and the necessity of driving a hole-in anchor in, as is done in conventional methods, is eliminated so that work is simplified. Because the wire 1 is pulled down when necessary, the wire 1 is not hung from the frame 9 when unnecessary.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire suspension device for suspending a fixture such as a lighting fixture on a ceiling body.

[0002]

2. Description of the Related Art Conventionally, there has been an example in which a lighting fixture is attached to a hanging bolt provided on a ceiling body. This suspension bolt is one in which a nut is embedded at the time of pouring concrete on the ceiling structure, the suspension bolt is screwed into this nut, the suspension bolt is cut in accordance with the length with the ceiling surface, and the lighting fixture is attached.

[0003]

However, if the position of the nut is displaced when the nut is buried, a hole-in anchor or the like is driven into the ceiling skeleton separately, and the suspension bolt is cut according to the ceiling height. The hanging bolt was screwed in and the lighting fixture was attached, so the work was troublesome.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a wire suspension device which can be easily adjusted in position and can be easily operated.

[0005]

A wire suspension device according to the present invention is a wire for suspending a device having a slider at an upper end thereof, and a box shape embedded in a ceiling body and capable of accommodating the wire. And a case for supporting the slider slidably along an edge of the slit.

[0006]

According to the structure of the present invention, the wire is pulled down through the slit of the case embedded in the ceiling body and is supported by the case by the slider. In this case, since the slider can freely move in the case, the position of the slider can be easily adjusted, and the work is simplified without the need to hit the hole-in anchor as in the conventional case. Further, since the wire may be housed in the case embedded in the ceiling body and pulled down from the slit when necessary, the wire does not hang down from the ceiling body when unnecessary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. That is, this wire suspension device has the wire 1 and the case 2. The wire 1 is for hanging a device having a slider 5 at the upper end. In the embodiment, the lighting fixture 4 is suspended. The slider 5 is inclined so that both opposite sides thereof are reverse tapered surfaces, and a through hole 6 having a large diameter portion and a small diameter portion is formed in the central portion. The slider 5 has a height of about 12 mm, a length and width of about 27 mm, and a minimum width of the lower end of about 20 mm. Diameter about 1.5mm, length about 1.5m
A rigid body 7 is provided on the upper end portion of the stainless steel wire 1, the wire 1 is passed through the through hole 6, the rigid body 7 is fitted into the large diameter portion, and is locked to the step portion 8 with the small diameter portion.

The case 2 is a box-shaped trapezoidal section which is embedded in the ceiling skeleton 9 and can accommodate the wire 1, and has a slit 3 for passing the wire 1 formed on the lower surface and a slider 5 for the edge of the slit 3. Support slidably along the part. Case 2 of the embodiment is made of metal and has a length of about 300 mm, a height of about 30 mm, a maximum width of about 35 to 40 mm, and a minimum width of about 20.
The both side plates are inclined in a reverse taper so as not to fall off from the concrete of the ceiling skeleton 9, and the mounting plates 10 are projected at both ends to form the mounting holes 11 in the mounting plate 10. 12 is a ceiling plate.

When the case 2 is embedded, the wire 1 is housed in the case 2 as shown in FIGS. 10 and 11, and
Slit 3 as shown in Fig. 6 to prevent concrete from entering
The adhesive tape 13 is adhered to the case 2, the case 2 is placed on the frame 14 such as a veneer plate as shown in FIG. 12, and the case 2 is temporarily fixed to the frame 14 by the nail 15 which is inserted through the mounting hole 11. At this time, the case 2 should be oriented in a direction that requires adjustment of the device position. And after that, concrete is poured. When the concrete formwork 14 is a metal deck plate, the adhesive tape 13 is double-sided tape as shown in FIG.

Further, when the adhesive tape 13 is peeled off during use, the wire 1 adhered to the adhesive tape 13 is also pulled down at the same time. In this case, when the attachment position of the instrument is deviated, the slider 5 is moved within the case 2 for adjustment. FIG. 14 shows a state in which the luminaire 4 is attached. For example, the wire 1 is passed through a wire rope adjusting detention metal fitting (made by Negros Co.) 16 and a rotation washer 19 of the detention metal fitting 16 is attached.
The edge of the mounting hole of the lighting fixture 4 is locked to the temporary fixing ring 2
0 and the nut 18 to attach the lighting fixture 4,
Is hung on wire 1. This retractor 16 is a wire 1
The luminaire 4 can be freely moved upwards along but is locked downwards, and the pin 17
By pulling, the lock (not shown) is released, the wire 1 becomes free, and the luminaire 4 can be moved downward.

According to this embodiment, the wire 1 is pulled down through the slit 3 of the case 2 embedded in the ceiling body 9 and supported by the slider 2 by the slider 5. In this case, since the slider 5 can freely move in the case 2, the position of the slider 5 can be easily adjusted, and the work is simplified without the need to hit the hole-in anchor as in the conventional case.
Further, since the wire 1 may be housed in the case 2 embedded in the ceiling skeleton 9 and pulled down from the slit 3 when necessary, the wire 1 does not hang down from the ceiling skeleton 9 when unnecessary.

The shape and the like of the case 2 of the present invention are not limited to the above embodiment.

[0013]

According to the wire suspension device of the present invention, a wire for suspending an appliance having a slider at its upper end and a box-shaped slit which is embedded in a ceiling skeleton and is capable of accommodating the wire are provided. And a case that slidably supports the slider along the edge of the slit, the slider can move freely in the case, so that the position of the slider can be easily adjusted. There is no need to hit the hole-in anchor so that the work becomes easier. Further, since the wire may be housed in a case embedded in the ceiling body and pulled down from the slit when necessary, the wire does not hang down from the ceiling body when unnecessary.
