Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to lighting equipment such as desk lamps or arm lights, and more particularly to a fixing structure for a lamp socket and a connection structure for connecting a support column made of a flexible pipe or the like for supporting a shade to the shade.

As shown in Fig. 1, a typical desk lamp consists of a base 2 equipped with a switch 1, and a shade 3.
and a support column 4 made of a flexible pipe or the like that connects the base part 2 and the shade 3 so as to support the shade 3. By the way, in the conventional desk lamp, as shown in FIG. 2, which is a sectional view taken along line A-A' in FIG. Even the inserted screw 7 was stuck to the shade 3. On the other hand, as shown in FIG. 3, which is an enlarged view of part B in FIG. 2, the connection structure between the pillar 4 and the shade 3 is such that a flange 8 is formed at the tip of the pillar 4, and this flange 8 is It was inserted through the inner surface of a mounting hole C drilled in the shade 3 and fixed to the shade 3 with screws 9, 9. In addition, this pillar 4
The lead wire a connected to the lamp socket 6 was inserted into the support 4 in order to supply power to the lamp socket 6.

Therefore, in the conventional desk lamp, the work of fixing the lamp socket 6 to the shade 3 at the rear end of the shade 3, which requires a small working space, and the work of fixing the lamp socket 6 to the shade 3 are difficult.
The work of connecting the desk lamp and the support post 4 is very difficult and has poor workability, and together with the large number of parts, this leads to an increase in the cost of the desk lamp.

The present invention is intended to solve the above-mentioned drawbacks, and provides a lighting fixture that is easy to work with and has a small number of parts.

Embodiments of the present invention will be described below with reference to the drawings.
In addition, FIG. 4 is an exploded explanatory view of the embodiment of the present invention, and FIG. 5 is a diagram of the completed assembly of the embodiment of the present invention, showing a cross section of the rear end of the shade.

In FIGS. 4 and 5, reference numeral 10 denotes a lamp socket having a substantially elliptical cross section, and a pair of support pieces 11, 11 projecting outward are provided at the upper part of the outer peripheral surface of the lamp socket 10 in the long axis direction. It is formed. In this lamp socket 10, a lead wire 1 for supplying power to this lamp socket 10 is provided.
2 and 12 are connected to connection terminals 13 and 13 provided on the rear end surface of the lamp socket 10. 14
The support column 14 is made of a flexible pipe or the like, and a flange 15 having a substantially rectangular flange shape is formed at the tip of the support column 14 . 16
is a shade, and an opening 17 is formed at the rear end of the shade 16. Reference numeral 18 denotes a support portion formed horizontally facing the opening 17, and includes a substantially elliptical hole 19 through which the lamp socket 10 is inserted.
a pair of support protrusions 21, 21 formed on both sides of the insertion part 20 in the longitudinal direction to support the support pieces 11, 11 of the lamp socket 10; Projection piece 21
and a connecting portion 22 that connects the shield 16 and the shade 16. Reference numeral 23 denotes a connection part for leading the lead wire 12 out of the shade 16 and connecting the support column 14 to the shade 16. This connection part 23 connects a part of the shade 16 near the opening 17 from the upper end. A notch 24 is cut out in a substantially U-shape downward, and a space of an appropriate thickness with an open top surface is provided on the outer periphery of the notch 24 in order to fit the flange 15 therein. The top plate 25 and the pillar 14
A cutout portion 26 is cut out downward from the upper end of the top plate 25 in a substantially U-shape for insertion thereof. Note that the shade 16, support portion 18, and connection portion 23 are integrally molded of resin or the like. A shade cap 27 is disposed to seal the opening 17 at the rear end of the shade 16, and has a lid shape with an open bottom. A pair of fixing bosses 28, 28 for fixing are vertically provided on the left and right sides. The fixing boss 28 has a cylindrical shape with an open top and a bottom, as shown in FIG.
It is disposed so as to face the support protrusion 21 of the lead-out portion 18 . A lid piece 29 is formed on one side in the longitudinal direction of the shade cap 27 and projects horizontally into a brim shape.
By fixing the connecting portion 1 in a sealing manner,
8 is for sealing the upper surface opening.

Furthermore, on the bottom of the fixing boss 28 of this shade cap 27 there are fixing screws 29, 2 for fixing it to the shade 16.
A screw hole 30 is formed into which the screw hole 9 is inserted and screwed, and the supporting piece 11 of the lamp socket 10 and the supporting protruding piece 21 of the supporting part 18 of the shade 16 are also provided at positions corresponding to the fixing boss 28. Screw holes 31 and 32 are formed at positions corresponding to the screw holes 30 formed in the fixing boss 28, respectively.

Assembly of the lighting fixture with the above configuration will be explained. First, the lead wire 12 is connected to the connection terminal 13 of the lamp socket 10 by soldering or the like, and the lead wire 12 is connected to the support 14 via the flange 15.
Insert it inside. Next, by inserting this lamp socket 10 into the insertion part 20 of the shade 16, the support piece 11 of the lamp socket 10 and the shade 1
The lamp socket 10 is assembled by joining the supporting protrusions 21 of 6.
is supported by the shade 16. On the other hand, the flange 15 at the tip of the support column 14 is inserted into the space of the connecting portion 23 of the shade 16, and the lead wire 12 is inserted into the notch 24, and the support column 14 is inserted into the notch 26, respectively. Next, attach the shade cap 27 to the shade 16 so that the lid piece 29 seals the top opening of the connection part 23.
The opening 17 at the rear end of the shade 16 is joined to the rear end surface.
Seal. Finally, insert the screw 29 into the fixing boss 28 of the shade cap 27, and then
By screwing these screws 29 into the screw holes 30, 31, and 32 formed in the fixing boss 28 of 7, the support piece 11 of the lamp socket 10, and the support protrusion 21 of the shade 16, the shade cap 2 can be attached to the shade 16.
Fix 7. Therefore, the lamp socket 10 is clamped between the shade cap 27 and the supporting part 18 of the shade 16, and the flange 15 of the support column 14 is connected to the connecting part 23 of the lid 2 of the shade cap 27.
9 is firmly fixed to the shade 16 by pressing and fixing it.

In addition, although the case where the shade cap 27 is fixed to the shade 16 with the screw 29 has been described,
The shade cap may be attached to the rear end surface of the shade with adhesive, or the shade can be attached by attaching the engaging claw formed on the outer surface of the shade cap to the engaging hole formed near the opening of the shade. The shade cap and the shade cap may be fixed together.

Since the present invention has the above-mentioned configuration, in conventional lighting equipment, the work of fixing the lamp socket to the shade at the rear end of the shade, which requires a small work space, and the work of connecting the shade and the support are very difficult. However, according to the present invention, the lamp socket is inserted from the rear of the rear end of the shade and supported by the support part, while a column with a flange fixed to the tip is connected to the connection part of the shade. By fixing the shade cap to the rear end of the shade, the lamp socket can be fixed and the support can be connected. In other words, the lamp socket can be fixed and the support column can be connected only by attaching from the outside of the shade, which provides a large work space, without having to do the installation on the inside of the shade as in the conventional case. Therefore, the workability of fixing the lamp socket and connecting the support column is significantly improved, and by making it possible to reduce the work cost, it is possible to reduce the cost of the lighting equipment.
