The whole of is completed. As described above, a required number of divided frame bodies having the same shape are prepared and screwed through the connecting member, and then the cover can be attached by one-touch mounting, which is an easy assembly operation.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Next, the board frame according to the present invention will be described with reference to the drawings. The board frame 1 is, for example, a wooden, synthetic resin, or metal frame that is attached as a cover at the periphery of a flat and rectangular panel board used for a ceiling or a partition. is there.
[0008]
As shown in FIGS. 1 and 2, the structure of the frame 1 has a length corresponding to each peripheral edge of the panel board, and connects the divided frame 2 of the hollow rectangular column and the adjacent divided frames 2. And a cover 4 that covers a connecting portion of the connecting member 3.
[0009]
The divided frame body 2 is, for example, a square having a hollow cross-sectional shape, and an opening 2b corresponding to the thickness of the panel board is uniformly provided along the longitudinal direction on one side surface 2a of the longitudinal direction. .
[0010]
A partition portion 2c is provided along the longitudinal direction at the central portion of the hollow inside of the divided frame 2. The partition 2c is a reinforcing member for the divided frame 2 and also serves to position the end face of the panel board 5 inserted into the hollow interior from the opening 2b as shown in FIG.
[0011]
Further, in the corner portion inside the hollow, a reinforcing member 2d having a desired length is provided at an inner position, and a mounting screw hole portion 2e is provided at an outer position.
[0012]
As shown in FIG. 1, the connecting member 3 is configured by integrally connecting two flat plates 3 a that close each end opening in the longitudinal direction of the adjacent divided frame bodies 2, 2 at their base portions 3 b. ing.
[0013]
The flat plate 3a is provided with a screw insertion hole 3c at a position corresponding to the mounting screw hole 2e of the divided frame 2, and a corner portion of the panel board 5 at the center. A notch 3d, which is an escape portion that avoids the contact, and a locking portion 3e that locks the cover are provided. The triangular plate 3f is a reinforcing member and is formed integrally with the flat plate 3a.
[0014]
Further, positioning members 3g to be inserted into the inner sides of the divided frame bodies 2 from the end openings are respectively provided on the back surfaces of the flat plates 3a and 3a.
[0015]
As shown in FIGS. 2 to 5, the cover 4 includes a cover body 4a that covers a gap formed between the end openings of the adjacent divided frame bodies 2, and an inner side of the cover body 4a. It is comprised by the latching claws 4b and 4c latched to the latching | locking part 3e of the member 3. As shown in FIG. The locking claw 4b is elastically deformed inward. The latching claw 4c is a projection part in which the protruding side surface part is hooked on the end surface of the latching part 3e.
[0016]
The arcuate notch 4d at the corner of the cover body 4a is a relief. Moreover, the panel board 5 is a charcoal board etc. as finishing materials, such as a ceiling, a floor, or a wall, for example.
[0017]
In order to apply the board frame body 1 configured as described above to the panel board 5, a description will be given with reference to FIG. 3. For example, each of the peripheral edges of the rectangular panel board 5 is divided from the opening 2 b to the divided frame. Insert body 2. Then, the positioning member 3 g is fitted into the lower end opening of the divided frame body 2 to place the connecting member 3. The corner portion of the panel board 5 does not enter and contact the notch 3d of the connecting member 3.
[0018]
Then, as shown in FIG. 1, the tapping screws 6 are respectively inserted into the holes 3c and screwed into the screw holes 2e by self-tapping, whereby the adjacent divided frame bodies 2 and 2 are respectively connected at the four corners. Is done.
[0019]
Next, the locking claws 4b and 4c are locked to the locking portions 3e of the connecting member 3 fixed to the corner portions, and the covers 4 are mounted with one touch.
[0020]
In addition to the above, the divided frame bodies 2 and 2 and the connecting member 3 or the cover 4 and the cover 4 are connected in advance to form an assembly, and the assembled divided frame body is mounted on the panel board 5. You may make it do. This assembling method includes a combination as appropriate.
[0021]
In this way, the panel board 5 having the frame body 1 attached to the peripheral edge portion of the board is disposed as a finishing material on the ceiling, wall or the like by hooks or the like.
[0022]
