Description

The present invention relates to a corner block mainly used for forming the four corners of a lattice. Specifically, it relates to a corner block for improving the rigidity of the lattice by devising the shape of the corner block for joining the frame members at the four corners of the lattice, and facilitating the separation of each material when the lattice is discarded. .

Conventionally, the material of the lattice is mainly made of resin or wood, and FIG. 13 shows a method of joining the four corners of the lattice. In many cases, the lattice is not a single material, but a plurality of materials such as screws, bolts, and corner blocks are made of metal, and the frame member and the lattice member are made of resin or wood. The case where the material of the frame member is resin is shown in FIGS. At the corner, the cut ends 28 and 28 of the frame member 2 are opposed to each other, and the L-shaped corner block 4 is laid across the portion. Then, the corners of the lattice are joined by screwing the staple 8 or the screw 9 in the direction of the arrow from the outside of the frame member 2. In this case, when the lattice is discarded, it is necessary to separate the metal staples or screws, the resin frame members or the lattice members for each material, which is troublesome.

Moreover, FIG.13 (c), (d) shows the case where a frame member is wooden. As in the case where the frame member is made of resin, the corners of the lattice are joined by screwing the staple 8 into the opposite frame member 2 from the outside of the frame member 2. In the case of such a wooden product, it is easy to rot, and the binding strength of the staple for joining the frame members is weak, and finally the whole is broken. Moreover, the metal steple is rusted and easily detached, and if the steple is rusted, the appearance is poor.

In the four corners of the lattice, gaps are likely to occur at the portions where the frame members are joined due to distortion or the like, and the exposed corners are not visually appealing. In addition, when carrying the lattice, it is easy to hit the corners, causing destruction.

In addition, when fixing the four corners of the lattice via a fixture such as a corner block, the frame member and the fixture are joined from the outside of the frame member using staples, screws, nails, etc. It is exposed and looks bad in appearance. In addition, a gap is likely to be generated at a joint portion between the frame member and the lattice member, and the exposed corner portion is unsatisfactory in appearance.

As described above, the conventional lattice corner block has various problems.

That is, the first problem of the conventional lattice corner block is that it is mainly made of metal, and is easily rusted and looks bad.

Further, in the conventional lattice, a plurality of materials, for example, staples, bolts, corner blocks, etc. are made of metal, and the lattice members are often made of resin or wood. When disposing of these, it is necessary to separate them into metal, resin and wood, which is troublesome. In addition, since the bolts and corner blocks are made of metal, the lattice becomes heavy, which is inconvenient when purchased and taken home at a home center, and difficult to handle when assembled at home.

And since a frame member and a corner block are couple | bonded using a staple, a screw, a nail, etc. from the outer side of a frame member, the head of a screw is exposed and its appearance does not look good. In addition, a gap is likely to be generated at a joint portion between the frame member and the lattice member, and the exposed corner portion is unsatisfactory in appearance.

Accordingly, the present invention has been made to solve such problems of the prior art, and provides a corner block that improves the bonding strength of the frame members at the four corners of the lattice and has a good appearance. For the purpose.

Furthermore, an object of the present invention is to provide a corner block that does not require time and labor for sorting by constructing a corner block mainly made of a resin material.

In order to achieve the above object, the invention of claim 1 is that the wings 42 and 42 open downward from the left and right sides of the left and right sides of the column 41, and the inner angle Q sandwiched between the wings 42 and 42 is approximately 90 degrees. And the cross-sectional shape comprised by the said support | pillar 41 and the said wings 42 and 42 is formed in Y shape, It is characterized by the above-mentioned.

The invention of claim 2 is characterized in that, in addition to the feature of the invention of claim 1, an umbrella 47 is provided at the upper end portion of the column 41.

It is possible to provide a corner block that improves the bonding strength of the frame members at the four corners of the lattice and has a good appearance. In addition, by constructing a corner block mainly made of a resin material, there is an effect that it does not take time for sorting during disposal.
