Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improvement in a fixing structure of a cover that covers heatons that support a lighting fixture main body by a wire.

(Prior Art) Conventionally, in a cover that covers a heat sealing for supporting a lighting fixture main body with a wire or a hooking ceiling that serves as a power supply unit, a locking claw is arranged around the periphery of a hole formed in the bottom of the cover, The power cord is passed through the hole, and the locking claw is locked and fixed to the power cord, or, as shown in FIG. 4, a heatn (B) for supporting the illuminator concrete (A) by the wire (C). ), An annular mounting screw part (D) is provided around the mounting base part, and a hole part (F) is provided in the bottom part of the cover (E).
After locking the wire (C) passed through to the heaton (B), screw the cover (E) to the annular mounting screw portion (D),
Some are fixed, or the wire (C) as shown in FIG. 5 is locked to the heaton (B) through the metal fitting (G), and the screw pipe is arranged at the tip of the metal fitting (G). (H) is projected from the hole (F) formed in the cover (E), and the cover (E) is fixed by screwing the screw cap (I) screwed onto the screw pipe (H) from the outside. There is something to do.

(Problems to be solved by the invention) However, in the above-mentioned conventional device, the locking claws are arranged around the periphery of the hole formed in the bottom of the cover, and the locking claw is provided by passing the power cord through the hole. For a power cord with a certain diameter, fixing with a locking claw is effective for locking the power cord with a power cord, but for a small diameter such as a wire, It cannot be fixed by the locking claws arranged on the periphery of the hole, and the lighting fixture main body cannot be held stably.
Furthermore, an annular mounting screw portion is provided around the mounting base of the heaton that supports the luminaire main body with a wire, and the wire passed through the hole of the cover is locked to the heaton. In the case of the one that is screwed and fixed, if the fixture main body is lifted by an external force and the wire sags, the wire locked in the heaton is easily disengaged, and the lighting fixture main body is likely to drop off. Also, lock the wire to the heaton via the metal fittings,
The screw pipe arranged at the tip of the metal fitting is projected from the hole formed in the cover, and the screw cap screwed onto the screw pipe is screwed from the outside. However, there are drawbacks that the number of parts is significantly increased, the cost is increased, and the work efficiency is reduced. Therefore, this invention is intended to improve the drawbacks of the above-mentioned conventional ones, and to secure the fixing of the cover with a simple structure.

(Means for solving the problem) For that purpose, the cover of the lighting fixture and its fixture,
The cover has a cylindrical fitting hole at the bottom, the fixing member is made of an elastic material, has a side wall having a polygonal horizontal cross section whose outer circumference is pressed against the fitting hole of the cover, and has a flange portion at the lower end periphery. A slit for penetrating and sandwiching a wire locked to a heaton is inserted from the side wall toward the center, and is fitted and fixed in a fitting hole at the bottom of the cover for covering the heaton.

(Operation) Since the fixing device of the present invention has the above-mentioned structure, when the wire is inserted into the slit and clamped in the cylindrical fitting hole opened at the bottom of the cover covering the heaton, it is fitted. , The side wall of the fixture is compressed by the tubular fitting hole to narrow the slit gap to securely clamp the wire, and the cover itself is also locked to the heaton by fitting into the fitting hole of the fixture. The upper edge of the cover is fixed so as to be in close contact with the ceiling and is stably supported, and the fixture itself is an elastic body and its cross section has a polygonal shape. Even if the diameter and shape of the cylindrical fitting hole at the bottom are different, the top part of the fitting side wall easily presses the outer periphery of the side wall of the fitting to the inner peripheral edge of the fitting hole, so that the fixing device of the present invention can be applied to many covers. It has versatility that can be applied to It Further, since the wire for fixing the cover is sandwiched between the slits of the cover fixing tool, when fixing the cover, the cover fixing tool should be removed from the middle of the wire without passing through the tip of the wire. Since the cover can be attached, the cover can be fixed easily and quickly.

(Embodiment) The invention will be further described with reference to an embodiment shown in the drawings. (1)
Is a support part of a lighting fixture body (2) equipped with the present invention, and the support part (1) is attached to the ceiling (3) with heatons (4).
And fixed via wires (5). The heaton (4) is fixed to the ceiling (3) by hooking a locking part (6) provided on the upper end of the wire (5) supporting the lighting fixture body (2), and covering the heaton (4). The cover (7) is inserted with a wire (5) for locking the cylindrical fitting hole (8) provided at the bottom of the cover (7) to the heaton (4), and the above-mentioned fitting of the cover (7) from below. The cover fixture (9) is fitted and fixed in the dowel hole (8). The cover fixture (9) is made of an elastic material such as rubber or resin, has a diameter larger than that of the fitting hole (8) and has a polygonal horizontal cross section, and the side wall (10). A slit (12) having a flange (11) provided on the bottom surface and holding a wire (5) whose upper end is locked to the heaton (4) extends from the side wall (10) to the flange (11), and the side wall (10). )
After the wire (5) which is provided so as to be oriented toward the center and supports the lighting fixture body (2) is clamped in the slit (12) of the cover fixture (9), the locking portion (6) of the wire (5) is held. ) Is attached to the heaton (4), and the cover fixture (9) is fitted into the tubular fitting hole (8) of the cover (7), so that the wire (5) is first attached to the side wall (10). Is larger in diameter than the fitting hole (8), it is tightened by the fitting hole (8), and the collar portion (11) abuts on the outside of the lower end of the fitting hole (8), and the upper end of the cover (7) is fixed. The cover (7) is easily fixed to the ceiling (3) by fixing the heaton (4) and the wire (5) since the cover (7) is closely fixed to the ceiling surface. At this time, even if the shape of the fitting hole (8) at the bottom of the cover (7) is different from the cross-sectional shape of the cover fixing tool (9) or the inner diameter of the fitting hole (9), the cover fixing tool (9). If the top of the side wall (10) having a polygonal cross section of (1) is pressed against the inner peripheral edge of the tubular fitting hole (8) of the cover (9), the cover fixing tool (9) will cover the cover (7).
