Description

[Detailed explanation of the idea] The present invention relates to the shape of a ceiling edge.

Traditionally, ceiling edges were rectangular and rod-shaped,
T-shaped cross sections having a vertical section and a horizontal section are well known. However, with the recent development of system ceilings, it is also known that the horizontal part of the ceiling edge, which has a convex cross-section, is inserted into a ceiling board having a female part to form a transparent part on the ceiling surface. If you want to make the board thinner and insert it into this horizontal part to make it look deeper by providing a cut-through part, it is not possible to form a fitting groove on the end surface of the ceiling board itself because it will weaken the strength. Nakatsuta.

This idea was created in view of the above circumstances.
The purpose of this is to make it possible to make the cut-out part look deeper without weakening the bending strength of the female part of the ceiling board even if the ceiling board is thin, and to make the ceiling area easier to install. It's about providing connections.

Hereinafter, an embodiment of the present invention will be explained based on FIG. 1.

A rectangular groove 4 is provided along the longitudinal direction near the center of the lower surface 3 of the horizontal portion 1 of the ceiling edge main body B, which has a convex cross section and has a horizontal portion 1 and a vertical portion 2. is forming. Further, hanging fitting locking grooves 5a and 5b for locking hanging fittings are provided at both ends of the ceiling edge A along the longitudinal direction of the vertical portion 2. Referring to FIG. 2, which shows the state in which this ceiling edge A is used, a rectangular plate 7 is bent into a U-shaped cross section in the hanging fitting locking grooves 5a and 5b provided in the vertical part 2 of the ceiling edge A. A locking part of a hanging fixture C, in which a locking part 6 is provided by slightly bending both ends inward, and a hanging fixture 8 is rotatably provided with a nail hole 11 in the vertical direction on the upper surface of the locking part 6. 6 is locked and fixed to a beam or crosspiece with a nail through a nail hole 11. Then, the female part 9 provided on the end surface of the ceiling board D is inserted so as to match the both ends of the grooves 4 provided on both horizontal parts 1 of the ceiling edge A, and the opening part 10 is inserted. We are trying to form a Incidentally, the circumferential surface of the groove 4 of the ceiling edge A may be decorated with decorative wood grain tape, paint, or the like. Furthermore, the shape of the grooves 4 may be triangular or the like and is not limited in any way. Therefore, since the grooves 4 are provided along the longitudinal direction near the center of the lower surface 3 of the ceiling edge A, even if the thickness of the ceiling board D is thin, if the depth of the grooves 4 is made deep, the opening effect can be achieved. can easily obtain a large ceiling. Moreover, the bending strength of the female part 7 of the ceiling plate D itself is not weakened.
Also, in this ceiling field A, there is a horizontal part 1 of the ceiling field edge main body B.
There are hanging fitting locking grooves 5a and 5b facing each other in the upper vertical part 2 and locking the locking part 6 of the hanging fitting C, so that the positioning of the hanging fitting C can be done using the hanging fitting locking groove 5a. , 5b. Since the nail head is not exposed from the horizontal part 1 of the ceiling edge A, the finish is beautiful and it is particularly useful as a Japanese-style open ceiling.

As described above, the present invention provides grooves along the longitudinal direction near the center of the lower surface of the horizontal part of the ceiling edge, so even if the ceiling board is thin, the bending strength of the female part of the ceiling board is strong. It is possible to form a deep opening without weakening the opening. or,
Installation of the hanging fitting is also easy due to the hanging fitting locking groove.
