Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a lighting fixture, particularly to a shade mounting device for a stand lighting fixture.

[Background technology]

2. Description of the Related Art Conventionally, as a shade mounting device for a stand lighting fixture, the one shown in FIG. 4 is known.
In this case, the shade 1 is constructed by fitting an annular seat 5 attached to the lower end of an arm 4 projecting downward inside the shade 1 into a socket 3 attached to the main body 2, and screwing a holder nut 6 into the male thread on the outer surface of the socket. are installed together. Similarly, a device as shown in FIG. 5 is also known, in which a support 8 is provided upwardly projecting from the base 7, and a shade support 9 is installed above the socket 3 from near the socket 3 attached to the upper end of the support 8. protruding,
An annular seat 5 attached to the lower end of the arm 4 protruding downward inside the shade 1 is fitted onto the fixing screw 10 provided at the tip of the shade support 9, and the nut 11 is screwed onto the fixing screw 1.
0, and shade 1 is attached. Sho 12
is a lamp.

However, in such a shade mounting device, when an external force is applied to the shade 1, the shade 1 rotates, and as a result, the holder nut 6 and the nut 1
1 rotated, causing problems such as the screws loosening and the shade 1 possibly coming off.

[Purpose of invention]

The present invention was devised in view of the above-mentioned drawbacks, and an object of the present invention is to provide a shade mounting device for a lighting fixture in which the shade is less likely to come off.

[Disclosure of invention]

This invention connects the lower ends of a plurality of arms protruding downward inside the shade with an elastically deformable arm support, provides a deep dish-shaped shade receiver at the lower end of the socket, and elastically deforms the arm support to connect the arms inside the shade receiver. Insert a shade fixture with arm holding parts near both ends into the shade holder, hold the arm with the arm holder, and insert the thumbscrew that passes through the shade holder into the shade fixture. Attach the shade by screwing it into the
Having achieved the object, the present invention will be explained below based on the embodiments shown in the figures.

1 to 3 show an embodiment of the present invention. Reference numeral 13 denotes an arm support that connects the lower ends of three arms 4 that protrude downward inside the shade 1, and has a substantially C-shaped cross section. The two ends of the arm 4 are located near the two arms 4. 14 is a deep dish-shaped shade receiver, and insert the lower end of the socket 3 inside.
It is fixed to the main body 2 together with the socket 3. The shade fixture 17, which is provided with arm holding parts 15 at both ends and has a screw hole 16 in the center, has a substantially cylindrical shape together with the arm support 13, as shown in FIG.

When installing the shade 1, in the free state, the arm support 1 has a larger diameter than the inner diameter of the shade receiver 14.
3 is inserted into the shade receiver 14 while being elastically deformed, and brought into contact with the inner surface of the shade receiver 14. Then, the shade fixing tool 17 is inserted into the shade receiver 14, and the arm holding part 15 is connected to the two arms. 4, and a thumbscrew 19 is screwed into the threaded hole 16 of the shade fixture 17 from the screw insertion hole 18 provided in the shade receiver 14, and the shade 1 is mounted while being prevented from rotating.

According to this embodiment, after the shade is attached, the shade will not be rotated and unattached due to external force, and the shade can be attached reliably.

[Effect of idea]

As described above, according to the present invention, it is possible to reliably prevent the shade from rotating without complicating the installation of the shade, and there is no risk of the shade coming off.

[Brief explanation of the drawing]

1 to 3 show an embodiment of the present invention, in which FIG. 1 is a perspective view, FIG. 2 is an exploded perspective view of the main part, and FIG. 3 is a plan view of the main part.

Claims (1)

[Scope of utility model registration request] The lower ends of a plurality of arms protruding downward inside the shade are connected by an arm support made of an elastic material in a substantially C shape that opens between two adjacent arms, and the outer diameter of the arm support in a free state is attached to the lower end of the socket. A deep dish-shaped shade receiver with a smaller inner diameter is provided, the arm support is elastically deformed and fitted into the shade receiver, and a shade fixture with arm holding parts near both ends is inserted into the shade receiver. The shade is attached by fitting the shade into the arm support, positioning the shade in the opening of the arm support, holding the arm with the arm holding part, and screwing a thumb screw passed through the shade receiver into the shade fixture. Shade mounting device for lighting equipment.
