[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cross-type lattice used for buildings such as gates and fences.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Publication No. 3-21426, a grid used in a building such as a gate is constructed by a grid frame material of up, down, left and right to form a quadrilateral grid frame. , A first lattice unit and a second lattice unit each having a plurality of lattice bars arranged in parallel in the lattice frame,
There is an arrangement in which both grid rails are placed one on top of the other such that they cross each other.

In each lattice unit, cutout portions are formed in the crosspiece supporting frame members arranged vertically and horizontally, and the end portions of the grid crosspieces are engaged with the cutout portions, and the grid crosspieces and the crosspiece support frame. The material is fixed with a fixture such as a screw. Then, the beam supporting frame members of the lattice unit are fitted into the lattice frame members of the lattice frame, and the fixtures at the end portions of the lattice beams are covered with the lattice frame members.

[0004]

In the conventional grid body, since the end portions of the lattice bars are engaged with the cutout portions of the beam supporting frame members, the cutting members having the same shape as the lattice bars are attached to each beam supporting frame member. There is a drawback in that the notch must be formed, and its processing is troublesome. Further, since the end portions of each lattice rail are fixed to the rail support frame members with fasteners such as screws while the end portions of each lattice rail are engaged with the notches of the rail support frame portion, many The fixing tool is required, and the fixing work is very troublesome, and there is a problem that the work efficiency decreases.

Moreover, since each crosspiece supporting frame member has a large number of notches having the same shape as the grid crosspiece, it is difficult to secure the strength by itself, and each crosspiece supporting frame member includes each grid crosspiece. Since there is a fixture that fixes the ends, it is necessary to fit the crosspiece support frame material of each lattice unit to the lattice frame material of the lattice frame to secure strength with this lattice frame material and at the same time hide the fixture. is there. Therefore, in order to maintain sufficient strength and improve the appearance, there is a drawback that the shape and structure of the lattice frame material are restricted, and the cost of the lattice frame material and other materials increases and the manufacturing cost increases. .

In view of the above conventional problems, the present invention has a simple support structure on the end side of the lattice bars of each lattice unit,
Each lattice unit can be easily assembled and can be manufactured at low cost. Moreover, the appearance of the lattice unit and the lattice body as a whole can be ensured sufficiently, and the appearance of the lattice unit can be improved. It is an object to provide a grid body that can be incorporated.
