Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a lattice structure in which a pair of lattice members each having sloped sides formed at their tips are abutted against each other.

Conventionally, as this kind of lattice structure, the one shown in FIG. 1 has been generally used.

If this thing is weak in strength simply by attaching a pair of lattice members 3゜4 formed with sloped sides 1 and 2 at the tips and abutting them, the sloped sides 1 and 2 are weak. 1. Form a slit 5 that spans the 1. It is something that

However, in order to manufacture this conventional structure, first, as shown in FIG. 2, slits 5 are formed in both lattice members 3 and 4, and isosceles triangular pieces 6 are prepared.

Next, as shown in FIG. 3, adhesive is applied to the inclined sides 1 and 2 so that they abut each other, adhesive is applied to both sides of the tear piece 6, and the tear piece 6 is press-fitted into the slit 5.

After the adhesive has dried, the excess portions protruding outward from the lattice members 2 and 3 are cut off to complete the lattice as shown in FIG.

Therefore, the above-mentioned conventional lattice structure requires time and effort to cut off the excess parts of the torn pieces after bonding, and this work must be done manually rather than by machine, and manual work requires skill and is expensive. There is a drawback.

Furthermore, although the strength of the abutting portions of the slanted sides is improved by the use of tearing, it does not contribute to the warpage of the grid material.

Also known as this type of lattice structure are the mitered miters and the mitered ones described on the second page of the Dictionary of Architectural Terms (published by Rikogakusha, 21st edition, April 10, 1939).

However, in the mitered joint, grooves are formed diagonally in the lattice members that are orthogonal to each other at the corners of the pair of lattice members, and the bars are fitted into these grooves, so the lattice members are prevented from warping. It does not contribute in any way.

Also, in flat miter saws, grooves are formed diagonally in the lattice members that are orthogonal to each other at the corners of a pair of lattice members, and the piece is fitted into this groove, so the lattice material It does not contribute in any way to the warpage.

SUMMARY OF THE INVENTION The object of the present invention is to eliminate the above-mentioned conventional drawbacks, and to provide a lattice structure that is simple in structure, easy to manufacture, and effective in preventing warpage of the lattice member.

The invention will now be described in detail with reference to the illustrated embodiments.

FIG. 5 is an exploded perspective view of the main parts of one embodiment, and FIG. 6 is a front view of the main parts in a completed state.

11.12 is a pair of lattice members, the tip of which is connected to the inclined side 13.
, 14 are in full form.

When lattice members 11 and 12 are assembled into a right-angled lattice, slope side 1
3.14 each form an angle of 45°, but it can be set to any inclination angle depending on the desired angle of the grating.

A long groove 15 is formed on the side surface of one of the lattice members 11 and extends linearly over almost the entire length along the longitudinal direction of the lattice member 11.

One end of the long groove 15 is open to the inclined side 13.

The other lattice member 12 has an end groove 16 that linearly communicates with the long groove 15 near the inclined side 14 thereof.

When the lattice members 11.12 are in a state in which their inclined sides 13.14 are abutted, the long grooves 15 and the end grooves 16 constitute one elongated groove that is in a straight line.

Reference numeral 17 denotes a bar that fits into the elongated groove, and both lattice members 1
1. Contributes to 12 connections.

Next, the assembly procedure will be explained.

Adhesive is applied to the sloped sides 13.14 of both lattice members 11.12, and then they are brought together, and then the rods are applied with adhesive in the linear elongated grooves, that is, the aligned long grooves 15 and end grooves 16. The material 17 is fitted.

When the adhesive is cured, the grid members 11 and 12 are attached to the bars 17.
A strongly connected grid is completed.

FIG. 7 shows a case where the present invention is applied to a long and narrow shade for a lighting fixture, in which the grid member 11 is located on the long side of the shade, and the grid member 12 is
constitutes the short side.

Linear long grooves are formed in the lattice member 11 over substantially most of its longitudinal direction, and when a bar is fitted into the long groove, the bar is used to prevent the lattice member 11 from warping. It is possible to make an effective contribution.

In the figure, 18 is a translucent member stretched over the grid, and 19 is an end plate.

FIG. 8 is a front view of main parts showing another embodiment of the present invention.

In this embodiment, both the lattice members 11 and 12 have linear long grooves 15, 15, and linearly communicating ends R16,
16, and bars 17, 17 are fitted into each grid member 11, 12, respectively.

Therefore, since warping can be prevented for both the lattice members 11 and 12, the lattice members 11 and 12 can be
This is effective when both 1.12 and 1.12 are long, and the bonding strength is also improved compared to the embodiment shown in FIG.

Although wood is usually used as the grid member in the present invention, it is not limited to this, and materials made of synthetic resin or other materials are also acceptable.

Further, both the bar material and the lattice member are not limited to the flat ones shown in the drawings, and may have any cross-sectional shape.

As described in detail above, the present invention has a pair of lattice members each having an inclined side at the tip; one side of the lattice member has a long groove extending linearly over almost the entire length, and the other side has an end groove linearly communicating with the long groove. Since straight bars are fitted and glued into these grooves, it is possible to provide an inexpensive lattice structure with a simple structure and good workability.

Further, by extending the rods and the long grooves linearly along the longitudinal direction of the lattice member, it effectively contributes to preventing warping of the lattice member.
