BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a lattice used for lighting louvers, window lattices, partition fences, and other decorative building materials, and more particularly to a lattice structure in which a plurality of frames are crossed with each other. It is about structure.

[0002]

2. Description of the Related Art Generally, paper shoji caskets are assembled in a lattice shape by crossing each other. As shown in FIG. 8, the lattice structure of such a paper shoji has a structure in which a plurality of first frames 1 arranged in parallel and a plurality of second frames 2 respectively intersecting with the first frames 1 are incorporated into each other. Has been The first frame 1 and the second frame 2 are
They are formed in substantially the same shape, and are made of a wooden board, a metal plate such as aluminum or iron, or a synthetic resin plate such as plastic.

As shown in FIG. 9 (A), the first frame 1 is cut along the width direction of the first frame 1,
A plurality of notched portions 3 formed to have a length that is approximately half the width of the first frame 1 are arranged in parallel along the longitudinal direction of the first frame 1 at predetermined intervals. In the second frame 2,
As shown in FIG. 9B, a cut portion 4 having substantially the same shape as the first frame 1 is formed.

A method of assembling such a lattice structure will be described.

[0005]

By the way, in the conventional lattice structure, when the width of the notches 3 and 4 is formed to be the same as or slightly smaller than the thickness of each frame 2 and 1 to be pressed. However, there is little risk that the frames 1 and 2 will fall out, but it becomes difficult to push in the frames 1 and 2.

On the other hand, if the widths of the notches 3 and 4 are formed to be larger than the thickness of the frames 2 and 1 to be pushed in, the frames 1 and 2 may fall out,
In order to increase the bonding strength between the cut portions 3 and 4 and the frames 2 and 1, an adhesive may be interposed between the cut portions 3 and 4 and the frames 2 and 1 to be pushed. Therefore, it is necessary to apply an adhesive or the like to the cut portions 3 and 4 of the frames 1 and 2, and the grid assembling work becomes complicated.

Further, the frames 1 and 2 assembled with each other
In order to increase the bonding strength of the above, a lattice structure in which the frames 1 and 2 are integrally molded is provided by integrally molding synthetic resin. With such a lattice structure, the cost required for a mold such as injection molding is high, and it is difficult to mold a large lattice by injection molding or the like.

Since the end portions of the reinforcing frames 11b and 12b of the other frame 10 that intersect with the side surfaces are in contact with the side surfaces, the trapezoidal side surfaces of the main frames 11a and 12a intersect the main frames 11a and 12a. Another frame 10
Are locked to the ends of the reinforcing frames 11b and 12b. Therefore, the main frames 11a and 12a can be prevented from coming off, and the reinforcing frames 12b and 11b are joined to the main frames 11a and 12a, so that the reinforcing frames 12b and 11b can be prevented from coming off. Therefore, since the intersecting frames 10 are locked to each other, the respective frames 10 can be prevented from falling out, the respective frames 10 can be firmly coupled, the safety of each frame 10 can be improved, and the intersecting frames can be pushed in. The work can be eliminated, and the workability of assembling the frame 10 can be improved.

Claims (3)

[Claims] 1. A structure of a lattice in which a plurality of frames are crossed with each other and incorporated, wherein the frames are joined to a first columnar body extending in one direction and the first columnar body in a laminated state. A second columnar body, and at least one of the first columnar body and the second columnar body is provided with a locking unit that is locked by another frame that intersects. The structure of the lattice to do. 2. The lattice structure according to claim 1, wherein the first columnar body and the second columnar body are each formed in a substantially trapezoidal shape in cross section, and the trapezoidal bottom surfaces are arranged to face each other. The structure of the lattice is characterized in that the ends of the second columnar body of another frame intersecting the first columnar body are in contact with each side surface of the first columnar body. 3. The lattice structure according to claim 1, wherein at least one of the first columnar body and the second columnar body is provided with a protrusion that is locked by another frame that intersects with it. The structure of the lattice characterized by that.
