Description

[Detailed explanation of the idea] This invention relates to an elevating type lighting fixture.

Conventional examples are shown in FIGS. 1 to 3.

That is, this elevating type lighting fixture has an elevating device 2 on the ceiling 1.
, connect the wire fastener 4 to the lower end of the wire 3 pulled down from the lifting device 2 with screws 5 and nuts 6, and attach the wire fastener 4 to the top surface of the instrument body 7 with screws 8, and attach the cap 9 integrally. It is installed.

Furthermore, the curl cord 11 is wound down onto the wire 3 from the ceiling 1 via the hanging ceiling 10 and guided to the appliance main body 7.

The device body 7 has an upper cover 12. A lamp support spring 13 and a support cylinder 14 are attached, and a lower cover 15 is attached to the support cylinder 14.
is attached by the handle 16, and the lamp 17 is attached to the lamp support spring 13.

16a is the switch pull string. In this elevating lighting device, the main body 7 of the device is raised and lowered using the handle 16, and is supported at a desired height by the elevating device 2.

However, this elevating type lighting fixture has the following problems.

That is, (1) when the device main body 7 is pulled down, the curl cord 11 stretches as shown in FIG. 4, and the inner side of the curl cord 11 at its lower end stretches the wire 3 in the lateral direction; This may cause the instrument to tilt.

(2) The relationship between the guide hole diameter of the cap 9, the outer diameter d1 of the curl cord 11, and its inner diameter d2 is D>dx>d2, but since it is greatly different from the outer diameter d3 of the wire 3, the curl cord 11 is It tends to become eccentric, and when the instrument main body 7 is moved up and down, it is not properly accommodated in the guide hole 9a of the cap 9 and ends up resting on the edge as shown by the imaginary line in FIG. 4, which is undesirable in terms of design.

(3) As the device moves up and down, the lower end of the curl cord also moves up and down, so this portion hits the wire fastener 4 and the screw 5 and easily scratches the insulation coating of the curl cord 11.

(4) When the main body 7 of the device is suspended from the wire 3, the vertical part of the wire stopper 4 is only fastened at two points at both ends 2, so the vertical part of the stopper 4 is deformed upward, and as a result, the stopper 4 The connection becomes unstable, and the stopper 4 cannot be formed from a thin plate, making the structure complicated.

Therefore, an object of this invention is to provide an elevating type lighting fixture that supports a curled cord without any problem and prevents deformation of a wire fastener.

An embodiment of this invention is shown in FIGS. 5 to 7.

That is, in this elevating lighting device, a cord guide 18 as shown in FIG. 6 is attached to the lower end of the wire 3.

The cord guide 18 has a protrusion 4 of the wire fastener 4 on the lower end surface.
A recess 19 is formed into which the coil cord 11 fits, a collar 20 is formed in the middle part, and the upper part of the collar 20 is formed into a truncated conical cylinder part 21 having an outer diameter smaller than the coil inner diameter of the curl cord 11. to stabilize the curl cord 11, and
A wire insertion slit 22 communicating with the cutout 20a of the collar 20 is formed, and the edge surface of the cutout 20a is provided obliquely in the curling direction of the curl cord 11 to improve slippage.

On the other hand, a presser stepped portion 23 is formed on the inner surface of the cap 9.

The other configurations are the same as those in FIGS. 1 and 2.

This cord guide 18 passes the wire 3 through the slit 22.
, wrap the lower end of the curl cord 11 around the cylindrical part 21, and connect the straight part extending from the lower end to the cutout part 20 of the collar 20.
a, and connect the recess 19 of the cord guide 18 to the protrusion 4a at the upper end of the wire fastener 4, and when attaching the cap 9 to the main body 7 with the screw 8, 4 are fixed together, the collar 20 of the cord guide 18 is pressed by the holding step 23 of the cap 9.

This configuration provides the following effects.

That is, (1) since the curl cord 11 is guided by the cap 9 on the outside and the cord guide 18 on the inside,
It has good centering, does not get caught eccentrically when going up and down, and is easily stored in the cap.

Therefore, the design effect is not impaired as in the conventional case. (2) Since the cord 11 is supported by the cord guide 18 even when it is stretched, the wire 3 is not stretched, and the instrument is not tilted due to this.

(3) The upper end of the wire fastener 4 is protected by the cord guide 18, and the lower end of the cord 11 can be directly connected to the
It does not hit the edge of the metal fitting and does not damage the cord 11.

(4) Cover the upper end of the wire fastener 4 with the cord guide 18, and then attach the top 20 of the cord guide 18 to the cap 9.
Because it is held down by the holding step 23, the protrusion 4 of the stopper 4
a is restricted from moving upward by the wire 3, and deformation of the stopper 4 is prevented.

Therefore, the fastener 4 and its attachment can be simplified, and as shown in the figure, two thin plates bent into an L-shape can be combined to form an inverted letter shape.

(5) Since the cylindrical portion 21 is tapered, the curl cord 11 is easily rolled into the cylindrical portion 21 when contracted.

(6) Even when the curl cord 11 is fully extended, the inside of the cap 9 cannot be seen due to the cord guide 18.

As described above, in the lifting type lighting device of this invention, the cord guide is provided at the lower end of the wire to support the lower end of the curl cord, and the cord guide is held down by the cap, so there is no eccentricity of the curl cord. The device does not need to be tilted, the curl cord is not damaged, and the wire fastener is not deformed.
