Description

[Detailed Description of the Invention] This invention relates to a mounting structure for attaching an inverted Fuji-shaped socket base to the main body of a lighting fixture.

Conventionally, this type of mounting structure has been shown in FIG. In the figure, 1 is the main body of the device, and 2 is a socket base having a substantially inverted Fuji shape.A mounting piece 3 cut and raised from this socket base 2 is fixed to the flange portion 1a of the device main body 1 with screws 4. . 5 is a lamp socket attached to the socket base 2, and 6 is a reflector.

In the device configured as described above, the mounting piece 3 of the socket base 2 is screwed to the flange portion 1a of the device body 1, so that the flange portion 1a prevents hands and fingers during sheet metal work, assembly work, and device installation work. Improvements are required from the standpoint of safety, as they are easily damaged. Furthermore, it is desired that the mounting structure of the socket base be stabilized in quality, labor-saving, or automated by machinery.

This idea was made in order to eliminate the above-mentioned drawbacks of the conventional device. A pair of notches are provided at the edge of the side plate of the main body of the device, which has a U-shaped cross section, and a locking hole is placed behind the notches. , insert the receiving metal piece on the side hanging from the socket base into the notch, insert the tongue piece provided on the mounting foot of the socket base into the locking hole, and bend the tip. The socket base is supported on the main body of the fixture, which improves the safety of sheet metal work and assembly work, stabilizes the quality of press work, and saves labor.Installation of a socket base for two lights. The purpose is to provide equipment.

An embodiment of this invention will be described below with reference to the drawings. In FIG. 5, reference numeral 11 denotes a device body having a U-shaped cross section, and both open end edges 12 of this body 11 are curled. Reference numeral 13 denotes a pair of left and right notches cut out in the edge of the side plate of the instrument body 11 in a substantially U-shape, 14 a locking hole opened behind the notch 13, and 15 a locking hole formed at the bottom of the locking hole 14. This is the guide section. 16
is a socket base to be fixed to the device main body 11, and has a base surface 16a formed by two slopes that serve as socket mounting surfaces wider than the width of the opening of the device main body 11;
The base surface 16a has a side edge 17 bent at right angles over the entire length of the slope, and a rectangular window hole 18 is opened in this side edge 17, and the outer end of the window hole 18 is a receiving hole. It is labeled gold piece 19. Reference numeral 20 denotes a mounting foot formed by cutting and raising the base surface 16a of the socket base 16 inwardly, and 21 a tongue piece further cutting and raising from this mounting foot 20.

Next, the operation for fixing the socket base 16 to the instrument body 11 will be explained. First, the notch 1 of the instrument body 11
3, 13, insert the receiving metal piece 19 at the outer end of the side 17 of the socket base 16 with the socket base 16 obliquely as shown in FIG. When rotated in the direction of the arrow, the tongue piece 21 of the mounting foot 20 of the socket base 16 pushes open the instrument body 11, passes through the guide portion 15, and eventually engages with the locking hole 14. Thereafter, by bending the tip of the tongue piece 21 that protrudes outward from the locking hole 14 as shown in FIG. 4, the socket base 16 can be stably supported on the device main body 11 (see FIG. 2). . In FIG. 2, 22 is a lamp socket attached to the socket base 16, and 23 is a lamp socket attached to the socket base 16.
is a reflector. In addition, in the above explanation, the instrument body 1
1, the socket base 16 is attached to the other end of the instrument body 11 in the same manner as above.
It is omitted in the figure.

As described above, according to this invention, the device body and the socket base are fixed by engaging the receiving piece and the tongue piece of the socket base into the approximately U-shaped notch and locking hole provided in the device body, respectively. At the same time, since the tongue piece is bent to the outside of the locking hole, the socket base can be easily attached to the device body without using screws, etc., without requiring high precision in sheet metal processing. Moreover, the fixing can be performed reliably, and it is also suitable from the viewpoint of safety, since hands and fingers will not be damaged during sheet metal work, assembly work, and equipment installation work. Furthermore, since the sides of the socket base are formed by bending the slope of the base over the entire length, they are so-called stiff and difficult to deform even if subjected to external force after being formed.
Therefore, the position of the window hole remains unchanged and assembly can be performed smoothly.
Moreover, it strengthens the sloped portion and prevents deformation when the lamp is attached to and removed from the socket. Furthermore, since the window hole is square, even if the notch is slightly misaligned due to deformation of the side plate of the device main body, this can be absorbed and the ease of assembly is not impaired. Furthermore, the mounting feet are formed by cutting and raising the base of the socket base, making it highly flexible.
The tongue piece can be smoothly inserted into the locking hole. It also has the effect of stabilizing quality and saving labor through pressing operations.
