Description

[Detailed Description of the Invention] The present invention relates to a structure for connecting two members.

For example, in lighting equipment in which a reflective shade with a U-shaped cross section or a triangular cross section is directly attached to the ceiling of a house, etc., side plates are attached to both ends of the reflective shade and the opening ends are closed. . by the way,
Conventionally, locking metal fittings with square holes formed in the upwardly sloped portions facing inward are fixed at both ends of the reflective shade, and locking metal fittings are formed on the other side plate in correspondence with the square holes of the locking metal fittings. A projection is formed, and the locking projection is inserted under the locking metal fitting and pushed in, and the locking projection is fitted into the square hole and locked, thereby attaching the side plates to both ends of the reflective shade. However, with this, the locking protrusion on the side plate must be inserted under the locking metal fitting on the reflector side and pushed in, making it impossible to clearly recognize the position of the locking protrusion, which makes it difficult to lock. It took time and effort to match the protrusion with the square hole of the locking fitting, and it was difficult to simply and quickly attach the side plate to the reflective shade. Particularly, when connecting two members using a plurality of locking protrusions and locking metal fittings, it takes more time to connect both members, resulting in poor workability.

In view of the above points, the present invention is an improvement on the above, in which a locking hole is formed in the upwardly sloping tongue portion of the locking metal fitting fixed to the end of the first member. , and a guide groove opened from the locking hole to the outer end surface of the locking fitting is cut out, and a locking protrusion is integrally formed at a predetermined portion of the second member, and the locking protrusion is connected to the guide. By fitting and locking into the locking hole through the groove, the two members can be connected simply, quickly, and reliably.

The present invention will be described below with reference to embodiments shown in the drawings.

In FIGS. 1 to 4, reference numeral 1 denotes a reflective shade (a first reflector) constituting a lighting fixture of a predetermined length with an approximately U-shaped cross section and side plates 3, 3 that are inclined outward on both sides of a top plate 2. (member), 4 is a locking metal fitting with its mounting portion 5 fixedly attached to both ends of the top plate portion 2 of the reflective shade 1; The bent portion 7 is formed into a curved shape to form a sloped portion 8 that slopes upwardly toward the inner side, an outer edge portion 9 that slopes upwardly toward the outer side, and a guide piece. is brought into pressure contact with the top plate portion 2 of the reflective shade 1. The tongue portion 6 of the locking fitting 4 is notched in a T-shape, and a rectangular locking hole 10 is formed in the center of the inclined portion 8. An open guide groove 12 having a predetermined width is formed in the outer end surface 11 of the guide groove 12 . Reference numeral 13 denotes a side plate (second member) having a predetermined shape for closing the openings 1a at both ends of the reflective shade 1, and a predetermined portion on the outer surface of the top plate portion 14 of the side plate 13 is provided as shown in FIG. For example, a hemispherical locking protrusion 15, which has a width slightly larger than the width of the guide groove 12 of the locking fitting 4 and which fits into and locks into the locking hole 10, is integrally provided.

When attaching the side plates 13 to both ends of the reflective shade 1, first coat the ends of the side plates 3 onto the ends of the reflective shade 1 from the outer surface, and then slide the side plates 13 toward the reflective shade 1. Push it in while holding it. Then,
Since the width of the locking protrusion 14 of the side plate 13 is slightly larger than the width of the guide groove 12 of the locking fitting 4, the locking protrusion 15 is partially guided by the guide groove 12 and bent. The portion 7 enters while pushing upwardly open the tongue portion 6 that is in contact with the top plate portion 2 of the reflective shade 1, and fits and locks into the locking hole 10 as shown in FIG.
Thereby, the side plate 13 is removably attached and fixed to the end of the reflective shade 1. Incidentally, the locking protrusion 15 can also be formed into a pillow shape having an inclined portion on one side.

FIG. 5 shows another embodiment of the present invention. That is, the locking fitting 16 of this embodiment is attached to the mounting portion 1.
The tongue portion 18, which is an inclined portion projecting from 7 and sloping upward toward the inside, is cut out in a T-shape, and a rectangular locking hole 19 is formed in the center of the tongue portion 18. From the stop hole 19, the tongue piece 18
An open guide groove 21 is formed in the outer end surface 20 of the guide groove 20, and the tongue pieces on both sides of the guide groove 21 are slightly bent upward and inclined to form guide pieces 22, 2.
Set it to 2. Note that the locking metal fitting 16 is attached to the reflective shade 1.
(first member) via the attachment portion 17, the outer edge corner portion 23 of the tongue portion 18 comes into pressure contact with the top plate portion 2 of the reflective shade 1. Reference numeral 24 denotes a locking protrusion that is integrally provided on the top plate portion 14 of the side plate 13 in place of the locking protrusion 15 of the above embodiment, and this locking protrusion 24 is designed to move smoothly under the guide piece 22. Its front surface is formed into an arc shape. The procedure for joining the two members in this embodiment is the same as in the previous embodiment, and will therefore be omitted.

It goes without saying that the present invention can be applied not only to the connection between a reflective shade and a side plate of a lighting equipment, but also to the connection of any other two members.

As explained above, the present invention provides a method for fastening a locking fitting having a tongue portion formed by bending a guide piece having one end sloping upward toward the inside and the other end sloping upward toward the edge of a first member having a predetermined shape, the bent portion being pressed against the edge of the first member, a locking hole of a predetermined shape being formed in the tongue portion of the locking fitting, and a guide groove of a predetermined width being cut out from the locking hole and opening to the outer end of the locking fitting,
On the other hand, a locking projection is integrally formed at a predetermined position of the second member of a predetermined shape, which is fitted and locked into the locking hole via the guide groove of the locking metal fitting, so that the locking projection, whose sliding surface is arcuate, can be fitted and locked into the locking hole simply by inserting it into the guide groove of the locking metal fitting, thereby making it possible to join the two members easily, quickly and reliably. Also, the structure is simple and low cost.
