Description

[Detailed description of the invention] The present invention relates to a cross lattice body.

Conventionally, in a cross lattice body in which a frame material is attached to the four circumferences of a lattice made of a plurality of lattice bars assembled in a cross shape, the frame material and each lattice bar are formed so that the frame material has a U-shaped cross section, for example, and each lattice bar is The ends were fixed by fitting into the grooves of the frame material. However, simply fitting and fixing the end portions of the lattice beams to the frame material has the drawback that both cannot be securely fixed, and the rigidity of the cross lattice body as a whole is reduced.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and it is an object of the present invention to provide a cross lattice body in which the frame material and each lattice crosspiece are securely fixed, and which has good overall rigidity.

That is, the present invention provides a lattice 3 formed by connecting a plurality of lattice bars 2 each having an inner cavity 7 in a cross shape, and the lattice 3.
In a cross lattice body consisting of a frame material 5 joined to each end 4 of the lattice 3, the joining of each end 4 of the lattice 3 and the frame material 5 is an insertion portion inserted into the inner cavity 7 of the lattice crosspiece 2. 8 and a leg portion 9 which is inserted into a mounting hole 13 drilled in the frame member 5 and has an insertion hole 11 and a slit 12 for inserting the insertion portion 10, and the insertion hole 11 is The cross lattice body is characterized in that each end 4 of the lattice 3 and the frame member 5 are fixed by inserting an insertion member 10 into the cross lattice body.

Hereinafter, embodiments of the cross lattice body of the present invention will be described in detail based on the drawings.

FIG. 1 shows an embodiment of the cross lattice body of the present invention, and numeral 1 in the figure is the cross lattice body.

The cross lattice body 1 is composed of a lattice 3 in which a plurality of lattice bars 2 are connected in a cross shape, and a frame material 5 such as a frame material or a stile that is joined to each end 4 of the lattice 3. Each end 4 of the lattice 3 and the frame material 5 are connected by a joining member 6
are connected via.

As shown in FIGS. 2 and 3, the joining member 6 includes an insertion portion 8 and a foot portion 9 that are inserted into the inner cavity 7 of the lattice crosspiece 2.
The leg portion 9 is provided with an insertion hole 11 and a slit 12 into which an insertion member 10 such as a screw or rivet is inserted. Insert the insertion part 8 of the joining member 6 into the inner space 7 of the lattice crosspiece 2, insert the foot part 9 into the mounting hole 13 bored in the frame material 5, and insert the insertion part 8 into the insertion hole 11.
Each end 4 of the lattice 3 is fixed to the frame member 5 by inserting an insertion member 10 into the lattice 3. At this time, since the foot portion 9 is provided with a slit 12, as the insertion member 10 is inserted into the insertion hole 11, the foot portion 9 expands and the lattice 3
The end portion 4 and the frame member 5 are firmly fixed.

Moreover, since the insertion member 10 is inserted into the insertion hole 11 of the leg part 9, it is firmly fixed even if the angle between each end 4 of the lattice 3 and the frame member 5 changes.

The cross-shaped connection between the lattice bars 2 is as shown in FIG.
4, 14 are formed and the notches 14, 14 are incorporated in a cross shape, and each lattice crosspiece 2,
2 is connected by a locking member 16 having locking protrusions 15 in the shape of a truncated cone at both ends. One of the locking protrusions 15 of the locking member 16 is inserted into the inner space 7 of the lattice crosspiece 2.
Similarly, the locking protrusion 15 at the other end is inserted into the locking groove 17 provided on the other lattice bar 2, and the lattice bar 2 and the lattice bar 2 are connected. Connect in a cross shape. The locking member 16 not only allows the lattice bars 2, 2 to be easily connected to each other, but also allows the lattice bars 2, 2 to be connected to each other by simply pressing the locking protrusion 15 into contact with the entrance of the locking groove 17. No matter what the cross shape is, that is, no matter what angle the lattice bars 2, 2 intersect, they can be connected.

Further, the locking protrusion 15 may be provided with a slit so that it can be easily inserted into the locking groove 17.

Although the embodiments of the present invention are configured as described above, unless it goes against the gist of the present invention, the lattice crosspiece, the lattice, the lattice end, the frame material, the joining member, the inner space, the insertion part, the foot part, the insertion hole, Specific shapes and structures of slits, mounting holes, etc.
The materials and their connection relationships can be changed in various ways.

As explained above, the cross lattice body of the present invention is
It consists of a lattice formed by connecting a plurality of lattice bars each having an inner cavity in a cross shape, and a frame material that is joined to each end of the lattice, and the joining of each end of the lattice and the frame material is as follows: It is formed through a joining member consisting of an insertion part inserted into the inner end of the lattice crosspiece and a foot part inserted into a mounting hole drilled in the frame material and having an insertion hole and a slit for inserting the insertion member, and the above-mentioned By inserting the insertion member into the insertion hole, each end of the lattice and the frame material are fixed, so each end of the lattice and the frame material are firmly connected, and the ends of the lattice and the frame material are firmly connected. This cross lattice body is strong and rigid regardless of the angle formed by the frame material.
