Description

[Detailed description of the invention] The present invention relates to a new lamp, and in particular, when attaching a sheet seal to the rear surface of a flange provided at the opening edge of a lamp body, it can be fixed simply and reliably without using adhesives or the like. The aim is to provide the best possible lighting equipment.

Several examples of structures for attaching the sheet gasket or end rubber to the flange of the lamp body in conventional lamps are shown in FIGS. 1 to 5.

In the one shown in FIG. 1, a sheet packing d□ is adhered to the rear surface of a flange provided at the opening edge of a lamp body a□ using adhesive C or the like.

In the case shown in Fig. 2, bolts e are installed at appropriate positions on the flange provided at the opening edge of the lamp body a2, and the bolts e are made to protrude rearward from the front and rear surfaces of the flange. A sheet packing having a hole f is brought into contact with the rear surface of the flange so that the bolt e is inserted through the hole f.

The one shown in Fig. 3 has a protrusion g slightly longer than the thickness of the sheet packing d3 on the rear surface of the flange provided at the opening edge of the lamp body a3, and a hole is formed in the seat packing at a position corresponding to the protrusion g. The seat packing d3 is brought into contact with the front and rear surface of the flange so that the projection g is inserted into the hole, and the top surface of the projection g protruding from the seat packing d3 is caulked with a crimping jig.

The one shown in FIG. 4 has an end rubber 11 having a U-shaped cross section fitted around the periphery of a flange b provided at the opening edge of a lamp body a4.

The lamp shown in FIG. 5 has an edge j projecting slightly forward from the periphery of the opening edge of the lamp body, and an end rubber i2 corresponding to the edge is fitted.

As described above, there are various structures for attaching the sheet packing or end rubber to the flange b of the lamp body a in conventional lamps. There were problems in that it was difficult to attach the flange b, and the seat packing d or the end rubber i easily fell off from the flange b.

Therefore, the devices shown in FIGS. 6 to 9 were devised.

First, in the lamp body shown in Fig. 6, an appropriate number of rectangular holes k are bored in the flange h provided at the brown opening edge of the lamp body, and the holes protrude forward from the front surface of the flange at positions spaced apart from each other. A plate-shaped fixing piece m is provided at a position corresponding to the hole k on the contact surface to the flange of the sheet packing, and a plate-shaped fixing piece m is provided at a position slightly closer to the base than the tip of the fixing piece m. A fitting hole n is formed so that when the fixing piece m is inserted into the hole k and bent toward the protrusion 1, it can be fitted onto the protrusion 1. The fixing piece m is brought into contact with the rear surface of the flange, and the fixing piece m is inserted into the hole k, the fixing piece m is made to protrude from the front side to the flange, and the fixing piece m is bent in the direction of the protrusion 1, and the fitting hole n of the fixing piece m is inserted into the protrusion 1. By fitting the sheet to the flange b6 of the lamp body a6, the sheet packing is fixed to the flange b6 of the lamp body a6.

In addition, in the one shown in FIG. 7, a plurality of conical pins O are formed on the rear surface of the lamp body a7, and a plate-shaped sheet packing d is brought into contact with the rear surface of the lamp body from the rear side of the lamp body. At the contact part with O, the pin O is forced to penetrate the sheet packing d5 by forcibly pressing the sheet packing, and the apex of the pin 0 protrudes from the sheet packing d5. The protruding pin 0 is caulked using a caulking jig.

Also, the lamp body shown in Fig. 8 is a8
A plurality of protrusions p are formed on the rear surface of the flank, a fitting hole q is formed at a position relative to the protrusions p in the sheet packing, and a substantially donut-shaped hole having a cylindrical portion at the center is formed behind the fitting hole q. A stopper part r is formed integrally with the seat packing d6.

Then, the projection p is fitted into the fitting hole q, and further into the cylindrical portion of the stopper r located behind it, and the sheet packing is fixed to the flange b8 of the lamp body a3.

Furthermore, the lamp body a9 shown in FIG.
Notches S are provided at appropriate intervals on the edge of the flange b6 of the lamp body, and the notches S are formed by a notch S□ that goes toward the center of the lamp body and a notch S2 that goes left and right from approximately the center of the lamp body. In other words, it has a cross-like shape.

The end rubber i3 has a U-shaped cross section, and a fitting portion t having a shape to be fitted into the notch is formed inside the position corresponding to the notch S.

Thus, the end rubber i3 is fixed to the periphery of the flange b9 of the lamp body a9 by fitting the fitting portion t of the end rubber i3 into the notch S provided on the periphery of the flange of the lamp body a9.

However, in the case of the one shown in Fig. 6, it is difficult to mold the sheet packing and the shape of the flange is complicated, the bent part of the fixing part m and the fitting hole n are easy to tear, or the flange is difficult to form. It took a lot of effort to attach the sheet to the h.

In addition, as for the one shown in Fig. 7, the sheet packing and the shape of the flange b7 are simple, but the apex of pin 0 must be caulked after the sheet packing is forcibly pressed and brought into contact with the flange. However, there are drawbacks such as the sheet packing near the crimped portion may be deformed, and crimping equipment is required.

Furthermore, the shape of the sheet packing shown in FIG. 8 is very complicated, so it is difficult to mold it, and it is also very difficult to manufacture a mold.

Furthermore, although the end rubber i3 and the flange h can be attached easily with respect to the one shown in FIG.
, and a large number of notches S and insertion parts t are required, which tends to cause misalignment of the positions of the notches S and insertion parts t, which poses problems in terms of accuracy. However, there was a problem in that it was costly.

This invention was developed in consideration of the above points,
The object of this invention is to enable a sheet gasket to be easily attached to a flange of a lamp body, to prevent it from coming off easily after attachment, and to have a simple structure and to be able to manufacture it at low cost. , an appropriate number of holes are provided in the flange provided at the opening edge of the lamp body, and a sheet packing is integrally formed with a protrusion that is inserted into the hole at a position corresponding to the hole, and the protrusion is inserted into the hole. The lamp body is characterized in that a protruding piece of the sheet packing is brought into contact with the rear surface of the flange so as to be inserted therethrough, and protrudes from the front surface of the flange of the lamp body, and is fixed by a rim arranged on the front surface of the flange.
