Description

[Detailed Description of the Invention] This invention relates to a two-member attachment structure, and particularly relates to an improvement in the attachment structure of a socket attachment fitting to an instrument body.

Generally, this type of lighting equipment has a socket mounting bracket attached to the end of the fixture body with a U-shaped cross section, a socket is attached to this socket mounting bracket, and a reflector and a fluorescent lamp are installed between the sockets facing each other in the longitudinal direction. It is composed of

Among the lighting equipment described above, a socket mounting bracket with a V-shaped or reverse Fuji-shaped side surface and sloped surfaces on the left and right is attached to the fixture body, and the socket is mounted on the left and right slopes of the socket mounting bracket, respectively. In dual-lamp lighting fixtures that are mounted perpendicular to a surface, the width of the socket mounting bracket is large relative to the fixture body, and two sockets are installed on the left and right, which tends to cause looseness and installation errors. Conventionally, the overlapping portions of both side plates of the device body and both side plates of the socket mounting bracket were attached by spot welding or the like.

However, spot welding was time-consuming and laborious.

In view of these points, this invention provides a two-member mounting structure that can significantly improve the attachability of the second member to the first member with a simple configuration. Explain with reference to.

In FIGS. 1 and 2, 10 is an instrument body (first member) having a U-shaped cross section, and its side plates 10a, 10b
A locking square hole 11 is formed in the bottom plate 10C, and a cutout hole 12 is formed in the vicinity of the locking square hole 11 with a part protruding inwardly in the bottom plate 10C.

4 overlaps, the tongue pieces 17, 17 open the cut holes 12 and 12.
The socket fitting 13 is fitted into the socket to prevent vertical wobbling between the instrument body 10 and the socket fitting 13.

To explain the attachment operation between the device main body 10 and the socket fitting 13 having the above configuration, first, as shown in FIG. In this state, a part of the mounting base 14 and the locking protrusion 16a 16b are attached to the instrument main body 10.
Insert into the locking protrusion 16a.

16b to the corresponding side plates 10 of the instrument main body 10.
It is arranged along the diagonal line of the locking square holes 11, 11 of a and 10b, and the external force on the mounting base 14 is released, and both side plates 14a, 14
b is restored, the locking protrusions 16a and 16b are inserted into the corresponding locking square holes 11.11, and one of the locking protrusions 16
The locking part 16a' of a is made to protrude outward, and the socket mounting bracket 13 in the inclined state is rotated relative to the instrument body 10, and the socket mounting bracket 13 is attached to the instrument body 10.
The mounting bases 14 of the locking protrusions 16a, 16
b stands up in the locking square hole 11, and one of the locking protrusions 16
The locking part 16a' of a is locked to the circumferential surface of the same square hole 11, and the tongue pieces 17, 17 of the base plate 14C of the mounting base 14 are inserted into the cutout hole 12°12 of the bottom plate 10C of the instrument main body 10. to complete the installation.

After that, the socket 18 is attached to the attachment holes 19 and 19 of the slope plates 15a and 15b of the socket attachment fitting 13, and a reflector plate (not shown) is attached.

In the above-mentioned installed state, the locking square hole 11 formed in the instrument body 10 and the locking protrusion 16 formed in the socket mounting bracket 13 are shown.
a, 16b prevents relative displacement in the longitudinal and width directions, and furthermore, the cut holes 12, 1
2 and the tongue pieces 17, 17 prevent relative displacement in the vertical direction.
3 will not come off, wobble, or create a gap.

In addition, the installation work is easy; the mounting base 14 of the socket mounting bracket 13 is compressed inward using its elasticity, and then inserted into the device main body 10 at an angle to release the external force on the mounting base 14. The locking protrusions 16 a and 16 b of the stand 14 are naturally inserted into the locking square holes 11 and 11 of the instrument body 10 , and then the socket mounting bracket 13 is rotated relative to the instrument body 10 and slid at right angles. For example, the locking protrusions 16a, 16b lock in the locking square holes 11, 11, and the tongue pieces 17,
17 are cut holes 12, 12 in the bottom plate 10C of the instrument body 10.
The device body 10 and the socket fitting 13 are connected to each other by fitting into the socket, and there is no need for other special fittings such as spot welding, and the installation work is simple.

In the above description, the locking square hole 11. is provided on the instrument main body 10 side.
11 and a locking protrusion 16 on the socket mounting bracket 13 side.
a and 16b are formed, but the same effect can be obtained even if a locking protrusion is formed on the instrument body 10 side and a square hole for locking is formed on the socket mounting bracket 13 side.

Further, although the locking protrusions 16 a and 16 b have different shapes, they may be aligned to one locking protrusion 16 a.
On the other hand, if vertical play is sufficiently prevented by fitting the cut hole 12 and the tongue piece 17, the locking protrusions 16a, 1
6b may be aligned with the shape of the other locking protrusion 16b.

Furthermore, during use, a heavy load acts on the socket mounting bracket 13, causing it to rotate relative to the device body 10, causing the locking protrusion 16a to rotate.
, 16b may come off from the locking square hole 11, as shown in FIG.
Fixing protrusions 21 a and 21 b are disposed at positions shifted in the longitudinal direction from the locking protrusions 16 a and 16 b on a and 14 b.
are provided protruding in the width direction, and both side plates 10a of the instrument main body 10,
Locking square holes 22, 22 corresponding to the fixing protrusions 21a, 21b are formed in 10b.

In this case, the fixing protrusions 21a and 21b are formed into arcuate surfaces so that the side to be inserted first becomes narrower so that they can be easily inserted into the instrument main body 10, and the dimensions of the locking protrusion 16a and the fixing protrusion 21a are The locking protrusions 12a and 12 are set to be slightly shorter than the dimension between opposing sides of the locking square holes 11 and 22, and when installed, the locking protrusions 12a and 12
b and fixing protrusions 21 a, 21 b are respectively locking square holes 1
In this case, the fixing protrusions 21 a and 21 b will be fixed to the fixing protrusions 21 a and 21 b so as to be engaged with the opposite sides of the square fixing holes 11 and 22 to prevent displacement in the longitudinal direction. Relative rotation between the instrument body 10 and the socket fitting 13 is prevented, and the attached state is more firmly maintained.

Furthermore, the number of tongue pieces and incision holes can be reduced to one each.

As explained above, according to this invention, when attaching the first member and the second member, it is possible to easily attach the first member and the second member without performing spot welding, etc. The first member and the second member are reliably connected by the fit between the part and the locking square hole and the fit between the tongue piece and the cut hole, and there is no possibility of wobbling, gaps, or It doesn't seem like it will come off.
