Description

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

The upper and lower rungs of the grid body are generally connected to each grid by screwing screws into the abutting portions of the upper and lower rungs and each grid. Therefore, even if a strong connection is possible,
The disadvantage was that it required a great deal of effort to connect a large number of screws. On the other hand, a connection structure in which insertion holes corresponding to the cross-sectional shape of the lattice are provided at the lattice mounting positions of the upper and lower beams and the ends of the lattice are inserted without using screws has been considered. With this connection structure, it is difficult to securely fix the grid, and there is a risk that the grid connection portions may become loose and rattle, which may impede the use of the grid.

The present invention has been developed in view of the above points, and the notches provided on one or both of the protrusions of the upper and lower beams and the lattice fit together, and the outer protrusions and inner protrusions provided on both sides of the lattice fit together. By using a structure in which the protrusions of the upper and lower beams are clamped together, it is possible to easily connect the upper and lower beams to each grid, and the connecting parts are firmly fixed to ensure that loosening and wobbling do not occur. The purpose is to provide a lattice body that prevents

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

Figure 1 is a partially omitted front view, Figure 2 a, b
are an enlarged cross-sectional view and a front view of the connection between the lower deck and the lattice,
Figures 3a and b are an enlarged plan view and a front view of the connection part of the lower deck, Figures 4a and b are sectional views taken along the line A-A and B-B in Figure 3a, and Figure 5 is FIG. 7 shows an enlarged cross-sectional view of a connection according to another embodiment of the lattice; In these drawings, the reference numeral 10 indicates upper and lower horizontal bars, 20 indicates vertical bars, and 30 indicates a grid, which are mainly extruded from metal such as aluminum.

The upper and lower legs 10 are composed of a main body 11 having a rectangular hollow cross section, and a protrusion 12 provided in the longitudinal direction of one side of the main body 11. And Uesa 10
The protrusions 12 are arranged so as to face each other, with the protrusions 12 facing downward, and the lower sill 10 with the protrusions 12 facing upward. In addition, the protrusions 12 of the upper and lower legs 10 have slit-like notches 1 at corresponding appropriate intervals.
3 is provided. Two notches 13 are provided at the same interval as the width of the main body 31 of the lattice 30, and the small protrusions between the notches 13 serve as insertion protrusions 14. The insertion protrusion 14 is inserted into the third position by slightly twisting the tip.
An inclined guide portion 15 as shown in FIGS. a and 4 a is formed to facilitate fitting of the grid 30 as described later. Furthermore, locking protrusions 16 are provided at portions of the protrusion 12 adjacent to the notch 13, which are formed by caulking the protrusion 12 in different directions.

On the other hand, the lattice 30 fits into the notch 13 of the upper and lower legs 10, and the main body 31 has a hollow rectangular cross section so that the insertion protrusion 14 fits into the lattice 30. On both sides of the main body 31, there are outer protrusions 32 that protrude outward from the main body 31 and come into contact with the side surfaces on which the locking protrusions 15 of the projecting pieces 12 of the upper and lower rungs 10 are provided; As shown in FIG. 2a, a pair of inner protrusions 33 are provided on each insert protrusion 14 to abut on the side opposite to the outer protrusion 32. In this case, the gap between the pair of outer protrusions 32 and inner protrusions 33 is approximately equal to or slightly wider than the thickness of the protrusions 12 and 14.

The upper and lower beams 10 and the lattice 30 have such a structure.
The fitting connection is performed as follows. That is,
First, the lattice 30 is positioned opposite the insert protrusion 14 in a state where it is inclined in the same direction as the inclined guide portion 15 formed at the tip of the insert protrusion 14 . Next, the lattice 30 is brought into contact with the side surface of the protruding piece 12 having the locking protrusion 16 with its outer protrusion 32,
The inner protrusion 33 gradually fits into the notch 13 so as to come into contact with the side surface of the insertion protrusion 14 opposite to the outer protrusion 32. As a result, the lattice 30 is guided by the inclined guide portion 15 of the insertion protrusion 14, and the lattice 30 is
0, and the protruding piece 12 and the insertion protruding piece 14 are firmly clamped. At this time, the locking protrusion 16 bites into the outer protrusion 32, so the upper and lower legs 10
The connection between the grid 30 and the grid 30 becomes even more solid.

As mentioned above, the connection between the upper and lower beams 10 and the lattice 30 is as follows:
This can be done by simply inserting and fitting the lattice 30 into the upper and lower legs 10, but if the inclined guide portion 15 is formed at the tip of the insertion protrusion 14, fitting the lattice 30 becomes easier. This makes the connection work even easier. In addition, even if the outer protrusion 32 and the inner protrusion 33 come into contact with the protrusion 12 and the insertion protrusion 14 from different directions, the upper and lower rungs 10 and the lattice 30 can be firmly connected without wobbling. However, if the locking protrusion 16 is provided, the connection becomes even more solid. Note that the locking protrusion 16 can also be provided on the insertion protrusion 14.

Furthermore, in addition to the above embodiments, the present invention can also be modified as shown below, for example. That is, the notches 13 can be provided not only on the protrusions 12 of the upper and lower beams 10, but also on the main body 31 of the lattice 30, or can be provided on both the protrusions 12 and the lattice main body 31 at half depths. Further, the inclined guide portion 16 formed at the tip of the insertion protrusion 14 to facilitate fitting of the lattice 30 can also be formed at the end of the inner protrusion 33 or the like. When the inclined guide part 16 is formed on the insertion protrusion 14 or the inner protrusion 33, the inclined guide part 16 is hidden inside the main body 31 of the lattice 30, so that the appearance of the lattice body is not spoiled. Furthermore, regarding the positional relationship between the outer protrusion 32 and the inner protrusion 33, the outer protrusion 32 and the inner protrusion 33 can be positioned on the same side, respectively, as shown in FIG. In this case, the inclined guide portion 15 of the insertion protrusion 14 can be formed by twisting the tip into a dish shape or bending it to one side.

As described above, according to the present invention, the upper and lower beams and the lattice,
Connection can be made extremely easily by just fitting without using screws, and the connection is made reliably and firmly by the outer and inner protrusions provided on the lattice, preventing loosening of the lattice connecting parts. There will be no sagging or the like that will interfere with the use of the grid.
