For example, the joint member 4 receiving portions 28, 35
In the fitted state, the joint member 4 and the receiving portions 28, 33 are symmetrical and in symmetrical positions with respect to the bisector S inside the member 4 passing through the corner of the curved or L-shaped cross section of the joint member 4. Form it so that

This makes it easy to manufacture the joint member 4, and when the joint member 4 is fitted, the receiving part 28,
Since either of the locking portions 41, 41 can be accommodated in the locking portion 33, the construction can be carried out efficiently. Therefore, as a basic design, it is preferable that the shape of the joint member 4 and the positions of the receiving parts 28 and 33 be symmetrical rather than asymmetrical.

The receiving portion 28 of the main body 2 may be formed into a groove having an arcuate cross section using the circumference of the screw hole 29 as shown in FIG. 1, or may be formed into a U-shaped cross section as shown in FIG. As shown in FIG. 1, the receiving part 27 of the indexing part 26 has a shape in which the upper surface of the hook-shaped tip is cut obliquely toward the L-shaped bent part.
As shown in the figure, the shape of the receiving portions 27 and 28 may be a simple hook shape without being cut, and the shapes of the receiving portions 27 and 28 are not limited to the above. The locking portion 32 of the bottom joint member 3 has a first
As shown in the figure, in addition to forming the part into which the tip of the receiving part 27 of the spotting part 26 enters into an arc shape, there are also third and fourth parts.
As shown in the figure, the shape may match the hook shape of the receiving part 27 of the indexing part 26, and the receiving part 33 may be formed with an arcuate groove as shown in FIG.
As shown in the figure, the grooves may have a U-shaped cross section, and the shapes of the locking portion 32 and the receiving portion 33 are not limited to the above. In addition to forming a locking part 41 by folding back the end of the leaf spring material, the joint member 4 has a fifth part.
As shown in the figure, the locking portion 41 may be formed straight without being folded back, and can be modified as appropriate.

(Effect of the invention) The boxes such as curtain boxes of this invention are the first
In addition, since the slide member can slide in the width direction within the range where the joint surface and bottom joint member can be fixed with screws, etc., it can be jointed to building parts where dimensions are difficult to adjust, such as walls and window frames, and to the box body. It is possible to close the gap between the bottom joint member and the bottom joint member, and
It can be easily installed without any additional processing, making construction more efficient.

Second, the structure can be similarly applied to the case where a lighting box or the like is housed in a wall surface or window frame other than a ceiling material.

Thirdly, since the left and right side frames of the main body can be formed from extruded materials of the same shape, the number of types of molds can be reduced, and manufacturing costs can be reduced. Furthermore, when installing the main body, it can be installed with either the left or right side frame relative to the ceiling material, wall surface, etc., so it can be installed efficiently.
