Description

[Detailed Description of the Invention] The present invention relates to a lattice body which is used as a fence for a balcony, a bay window, etc., by connecting a plurality of lattices at regular intervals to upper and lower beams.

The connection between the upper and lower bars and each lattice in a lattice body is generally done by screwing screws into the abutting parts of the upper and lower bars and each lattice, and therefore, although a strong engagement can be achieved, it is difficult to connect a large number of screws. The disadvantage was that it required a great deal of effort to connect. On the other hand, a connection structure in which the abutment parts are inserted into each other without using screws has been considered, but this connection structure is difficult to secure firmly and also causes loosening, rattling, etc. in the lattice connection part. There was a fear that this would interfere with the use of the grid.

The present invention was developed in view of the above points, and by making the protrusions provided on the upper and lower bars and the clamping parts provided on each grid into a fitting structure, it is possible to easily connect the upper and lower bars and each grid. It is an object of the present invention to provide a lattice body in which the above-mentioned fitting parts are compressively deformed to firmly fix the connecting parts and reliably prevent the occurrence of loosening, rattling, etc. It is.

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a front view of the lattice body, FIG. 2 is a sectional view taken along the line AA in FIG. 1, FIG. 3 is an enlarged view of the main part of FIG. 2, and FIG. 4 is an exploded perspective view of the lattice body.

In each of the above figures, the lattice body of this embodiment has a plurality of lattices 2,
2, and is constructed by fitting and fixing the uneven strips 4 provided on the projecting pieces 3 of the upper and lower crosspieces 1 into the clamping portions 5 provided on the lattice 2.

Each of the above-mentioned upper and lower crosspieces 1, 1 is constructed by providing a projecting piece 3 made of a thin plate-like piece in the longitudinal direction on each opposing surface of a main body having a hollow rectangular cross section. On both side surfaces of this protruding piece 3, uneven strips 4 are formed by providing a plurality of protruding stripes in the lateral direction at predetermined intervals. An arbitrary horizontal groove is provided between each of the above-mentioned protrusions. The uneven strips 4 may also be provided only on one side of the projecting piece 3.

The lattice 2 is constructed by providing clamping parts 5, 5 in the longitudinal direction of both sides of a main body having an arbitrary hollow cross section. This holding part 5 consists of two plate pieces 5a, 5a.
It has a substantially H-shaped cross section connected by a rib piece 5b, and the interval between the plate pieces 5a, 5a is made to approximately match the outer width of the protruding piece 3 provided with the above-mentioned uneven strips 4. The holding portion 5 may also be provided only on one side of the grid 2.

As shown in FIG. 4, the holding parts 5, 5 of the lattice 2 have notches 6, 6 formed by cutting out the rib pieces 5b at a portion corresponding to the length of the protruding piece 3 from the upper end. The protrusions 3 are fitted into the notches 6, 6 of the clamping parts 5, 5 to clamp them.

The clamping parts 5, 5 provided with the notch 6 are connected to the projecting piece 3.
After fitting, as shown in FIG. 3, pressure is applied from both sides to compress and deform the protruding piece 3, thereby fixing it to the uneven strip 4 of the protruding piece 3. That is, by pressing the clamping part 5 from both sides, the inner wall of the clamping part 5 is press-fitted into each recess of the uneven strip 4, and the two are firmly fixed. Note that the clamping portion 5 and the uneven strips 4 are fixed also between the lower crosspiece 1 and the lower end of the lattice 2.

The above-mentioned upper and lower crosspieces 1 and each lattice 2 are mainly formed from extruded aluminum. Therefore, the cutout portion 6 of the holding portion 5 can be easily formed by cutting out the rib piece 5b after molding with a mold material. Note that 8 in FIG. 1 is a vertical bar.

Moreover, the cross-sectional shapes of the above-mentioned upper and lower crosspieces 1 and the lattice 2 can be arbitrarily selected.

As described above, in the lattice body of the present invention, the protrusions provided on the upper and lower bars fit into the gripping parts of the lattice through the notches provided in each lattice, so the connection between the upper and lower bars and each lattice is achieved by screws. This eliminates the need for the use of the top and bottom bars, making it extremely easy to carry out.Moreover, since the notches are formed in a grid, the fixing positions in the longitudinal direction to the top and bottom bars are not limited and can be set arbitrarily. By providing a large number of uneven stripes, which are compressed and deformed after being fitted into the gripping portions of the lattice and then fixed, the connection between the projecting pieces and the holding portions can be made strong, and the large number of uneven stripes and By doing this, you can fix it by just deforming the whole part little by little, and the deformed part is not noticeable.
Furthermore, it is possible to reliably prevent loosening, rattling, etc. from occurring in the connecting portion.
