DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. 1 is a long tool body, and a flat wall 1A,
A side wall 2 is formed by folding both side edges thereof, and socket bases 3 are installed at both ends as shown in FIG. Reference numeral 4 denotes a socket attached to the socket base 3. A lighting device 5 necessary for lighting the discharge lamp L is housed inside the appliance body 1. These configurations are not particularly different from conventional lighting fixtures.

According to the present invention, a vertical hole 6 extending in the depth direction of the side wall 2, a first horizontal hole 7 communicating with an upper end of the vertical hole 6 and extending in the length direction of the side wall 2 are formed on both side walls 2. A second horizontal hole 8 communicating with the lower end of the vertical hole 6 and being parallel to the horizontal hole 7;
And an arc-shaped hole 9 along a circle centered on the tip of the lateral hole 7.

The vertical holes 6 are formed in both side walls 10 of the socket base 3.
Is formed into a bridge-shaped cut-and-raised piece 11 which can be inserted through the bridge. Further, with the cut and raised piece 11 inserted into the vertical hole 6 being moved in parallel to the ends of both the horizontal holes 7 and 8, the lower end of the cut and raised piece 11 is placed along the arc-shaped hole 9 around the tip of the horizontal hole 7. When the cutting piece 11 reaches the tip of the arc hole 9, the side wall 2 of the instrument main body 1 is connected to the socket base 3 by guiding the rotation along the peripheral surface of the arc hole 9. Protrusions 12 for pushing in a direction away from the side wall 10 are provided on both side walls 10 of the socket base.

Before the lighting equipment is shipped from the factory, the socket base 3 is incorporated in the equipment main body 1. In this installation, as shown in FIG. 3, the socket 4 is turned down inside the instrument body 1, and the inside of the side wall 2 of the instrument body 1 faces the outside of the side wall 10 of the socket base 3. Then, the cut and raised piece 11 is inserted from the inside of the instrument body 1.

Next, when the socket base 3 is moved in parallel toward the inner end of the instrument main body 1, as shown in FIG.
Each end of 1 passes through the horizontal holes 7 and 8 and reaches the tips of the horizontal holes 7 and 8 as shown in FIG. A bulging portion 13 is provided on a part of the peripheral surface of the horizontal hole 7 to partially reduce the width of the horizontal hole 7. This makes it difficult for the cut and raised piece 11 reaching the position shown in FIG. 5 to return to the position shown in FIG. That is, the movement of the socket base 3 along the longitudinal direction of the instrument body 1 is restricted.

Since the cut-and-raised piece 11 is engaged with the distal ends of the two lateral holes 7 and 8, the movement of the socket base 3 along the depth direction of the instrument body 1 is restricted. As described above, the socket base 3 is incorporated into the appliance main body 1 and, in the assembled state, the movement of the socket main body 1 in the front-back, left-right, and up-down directions is restricted.

In this state, the instrument body is packaged together with another instrument, for example, a reflector, and shipped from the factory.
In order to assemble the socket base 3 on site, it is sufficient to rotate the socket 4 approximately 90 degrees so that the socket 4 stands up as shown in FIG. As a result, the cut-and-raised piece 11 rotates so that one end thereof is centered on the tip of the horizontal hole 7 and the other end passes through the inside of the arc-shaped hole 9, passes through the state shown in FIG. To reach.

In this process, since the projection 12 moves along the peripheral surface of the arc-shaped hole 9, the rotation is guided. And FIG.
In the state reached at the position shown in (1), the other end of the cut-and-raised piece 11 hits the tip of the arc-shaped hole 9 and further rotation is restrained.

The projection 12 passes through the arc-shaped hole 9 and passes through the side wall 2.
Facing the inside of the body, the body
Is pushed outward. As a result, the position of the cut-and-raised piece 11 is restrained while straddling between the tip of the horizontal hole 7 and the tip of the arc-shaped hole 9. As described above, the socket base 3 is fixed to the appliance main body 1 in a normal state during use.

[0016]

As described above, according to the present invention, when shipped from a factory, the socket base is stably connected to the appliance body, and is integrated with the appliance body without being separated from the appliance body. It is not necessary to package only the socket base because it is wrapped in a package, and the socket base is not forgotten and packed. It is only necessary to rotate the device, and it is possible to stably fix the device to the device main body only by the rotation.
