Description

[Detailed explanation of the invention] This invention relates to a stand-type lighting fixture using incandescent lamps, etc. A decorative louver is attached to the bottom of the globe that contains a socket, a lamp, a reflective shade, etc., and an opening at the bottom of the globe is used. In addition to improving the appearance shape by covering the
To provide a lighting fixture in which the louver can be easily attached to a glove in a one-touch manner, and furthermore, a reflective shade can be used to prevent the louver from falling.

Hereinafter, the configuration of this invention will be explained according to the embodiments shown in the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a flexible pipe for accommodating and guiding a connecting cord and for arbitrarily adjusting the lamp installation position, and its base is appropriately attached.

Reference numeral 2 denotes a glove attached to the tip of the flexible vibrator 1, which has a small diameter at the top and a large diameter at the bottom, which houses and protects each component and adjusts the direction of irradiation.

3 is a socket attached to the lower part of the glove via a mounting bracket 5, and 4 is an incandescent lamp inserted into the socket 3.

The mounting bracket 5 is bent into a substantially U-shape, and is inserted into the small diameter portion 2a of the glove 2 with the opening side facing downward, and the upper flat surface 5a is brought into contact with the top surface of the glove 2, and the decorative Screw 6.
6, the socket 3 is inserted into the recess of the mounting bracket 5, and is brought into contact with a cut-and-raised piece 7 formed by cutting out a part of one side surface 5b of the mounting bracket 5, and then screwed 8 and mounted.

Reference numeral 9 denotes a reflective shade attached to the lower flange portion 5c of the mounting bracket 5, which surrounds the lamp 4 and diagonally rearward thereof to reflect light.

Reference numeral 11 is a translucent looper attached to the lower part of the globe 2, which forms a small lower opening, covers the lower opening of the globe 2, and surrounds the lamp 4 and the reflective shade 9 to improve the appearance. It is attached to the glove 2 in a one-touch manner, and is prevented from falling by a reflective shade 9.

Both the glove 2 and the looper 3 are made of synthetic resin, and as shown in FIG. 3, the glove 2 has three locks arranged at appropriate positions on the inner peripheral edge of the circular lower opening, for example, around the circumference. A protrusion 12 is formed to face inward, and a taper 13 with an upward slope is formed inward on the lower surface side of the locking protrusion 12.
The looper 11 is formed to facilitate fitting with the looper 11.

On the other hand, the looper 11 has a lower opening smaller than the upper opening, and the circumferential edge of the circular upper opening is thickened as shown in FIG. This annular step 15 forms an annular step 15 that fits on the circumferential surface.
The lower surface of the globe 2 is supported on the plane 15a of the vertical wall portion 1.
A locking window 16 is formed in the groove 5b at a position corresponding to the locking protrusion 12 of the groove 2, and a locking window 16 is formed at an appropriate position on the inner circumferential surface, for example, at a circumferential position, so that the locking window 16 is formed in a position corresponding to the locking protrusion 12 of the groove 2. 17 is formed.

Further, as shown in FIG. 5, the lower end of the reflective shade 9 is bent outward to have the same diameter as the upper inner circumferential surface of the looper 11, and a portion of the looper 11 corresponding to the engaging piece 17 is cut out. 19, forming a flange portion 18 that can be inserted;
The engaging piece 17 and the flange portion 18 can be inserted relative to each other at a specific location, and when rotated, the two engage to prevent them from coming off.

However, the relative positional relationship between the engaging piece 17 of the looper 11 and the flange portion 18 of the reflector 9 is such that when the looper 11 is attached to the glove 2 and the reflector 9 is attached to the bracket 5, the two overlap. and engages with each other, and the flange portion 18
The engagement piece 17 is pushed up to form the glove 2 and the looper 11 in tight contact with each other.

In the above configuration, in order to assemble the lighting equipment, attach the globe 2 to the tip of the flexible pipe 1, then insert the mounting bracket 5 into the globe 2 with the opening side facing downward, and screw it into the decorative screw 6.6. After that, attach and fix socket 3.
is inserted into the mounting bracket 5, and screwed 8 with the rear end brought into contact with the cut and raised piece 7.

Then, the lower part of the reflective shade 9 and the upper part of the looper 11 are made to correspond to each other at another position, the notch of the flange part 18 and the engagement piece 17 are aligned, and the flange part 18 of the reflective shade 9 is inserted into the louver 11. Thereafter, the two are rotated relative to each other by a predetermined angle, the flange portion 18 and the engagement piece 17 are overlapped, engaged and temporarily fixed, and in this state, the reflective shade 9 is inserted into the glove 2, and the annular step of the looper 11 is The part 15 and the lower part of the glove 2 are made to correspond, the locking protrusion 12 and the locking window 16 are matched, and the two are fitted together.

Then, since the glove 2 and the looper 11 are made of synthetic resin, the taper 13 of the locking protrusion 12 deforms outward along the vertical wall portion 15b of the annular step portion 15 and passes over it.
When it matches the locking window 16, it is elastically restored, and the locking protrusion 12 fits and locks into the locking window 16 to prevent it from falling, and at the same time, the vertical wall portion 15b and the lower inner circumferential surface of the glove 2 fit together. and the lower part of the glove is brought into contact with the flat surface 15a of the annular stepped portion 15.

After this, the upper part of the reflective shade 9 is attached to the flange portion 5c of the mounting bracket 5 with the screws 10, and the lamp 4 is inserted into the socket 3 to complete the assembly.

When disassembling it, just do the opposite operation to the above.

In the above assembly, the locking protrusion 12 and the locking window 16 are fitted and fixed, and at the same time, relative rotation between the glove 2 and the looper 11 is prevented, and the flange portion 18 of the reflector 9 is connected to the looper. The looper 11 is engaged with the engagement piece 17 of the glove 2 to prevent the looper 11 from falling.
Since it is pressed to the side and tightly adhered, the assembly part becomes solid, the looper 11 does not come off, and a one-piece appearance is obtained.

Also, since the reflective shade 9 and the looper 11 can be temporarily fixed,
Work becomes easier.

In the above description, a case has been described in which the looper 11 is used in which the lower opening is smaller than the upper opening, but the shape of the looper 11 is not limited to this. A larger looper may be installed.

In this case, since the reflective shade 9 can be inserted through the lower opening of the looper 11, the flange portion 1 formed on the reflective shade 9
8 and the engaging piece 17 formed on the looper 11 may be formed in series on each curved surface and engaged, and there is no need to set a relative positional relationship, which facilitates manufacturing.

As explained above, according to this invention, the three parts of the glove, looper, and reflective shade are engaged to form a strong assembly structure, and the louver does not come off and has an integrated external shape. At the same time, since the lower opening of the glove is covered with a louver, the inside cannot be seen from the side or diagonally, and the appearance is greatly improved.

In addition, since the glove and louver are connected by fitting, they can be assembled in one touch, and the louver can be temporarily secured with a reflective shade, greatly improving work efficiency.
