Description

[Detailed Description of the Invention] The present invention relates to a grid made of metal profiles.

Conventionally, in a lattice made of metal profiles, a horizontal lattice is fitted into a notch formed in the vertical lattice, and a back plate extending from the back side of the vertical lattice to the entire length of the vertical lattice is snapped onto the vertical lattice using its elasticity. A structure adapted to engage is disclosed. However, elastically engaging long back plates in this way requires a large amount of force and is not only difficult to assemble, but also requires the use of an elastic plate for the back plate. There was a problem in that the pressing force was weak, and the connecting parts of the grid were likely to rattle, especially in items that were frequently subjected to shocks, such as sliding doors and doors.

Furthermore, since the back plate needs to be long enough to span the entire length of the vertical lattice, there is a drawback that the material cost is high.

The object of the present invention is to provide a lattice that is inexpensive, easy to assemble, and does not cause rattling by connecting a vertical lattice and a horizontal lattice with small pieces of connectors.

The present invention will be explained below based on embodiments shown in the drawings. FIG. 1 shows an example of an entrance sliding door 1 equipped with a lattice according to the present invention, where 2 is a vertical stile, 3 is an upper stile, 4 is a lower stile, and 5 is a lattice consisting of a vertical lattice 6 and a horizontal lattice 7.

As shown in FIG. 5, the vertical lattice 6 has side walls 8, 8 with tapered portions 8', 8' toward the front, and a narrow front portion 9. The rear portion is an opening 10, and the opposing inner surfaces of the side walls 8, 8 are provided with a pair of guide grooves 11, 11. A notch 12 corresponding to the shape of the horizontal lattice 7 is formed in the side walls 8, 8 from the rear side to the front side of the vertical lattice 6. The horizontal grid 7 is the side wall 1
3, 13, tapers 14, 14, and a narrow front surface 15, and a partition wall 16 between the side walls 13, 13,
The rear end portion is provided with opposing protruding edges 17, 17. In the side walls 13, 13 of this horizontal lattice 7, a notch 18 extending to the surface of the partition wall 16 is cut out in the vertical direction of the vertical lattice 6. The thickness T (FIG. 3) of this horizontal lattice 7 is the same as the depth of the notch 12 of the vertical lattice 6. Therefore, when the horizontal lattice 7 is fitted into the notch 12 of the vertical lattice 6, both the lattices 6, The rear surface of 7 is the same surface.

Reference numeral 19 denotes a connector made of synthetic resin or the like, which has a rectangular main body 20 with a pressing protrusion 21 on its inner surface, and a handle 22 on its upper part if necessary.

Next, the assembly procedure will be explained. As shown in FIG. 4, the connector 19 is inserted into the guide grooves 11, 11 from the vertical lattice 6, the notch 12, or the upper end thereof, and is placed above the notch 12. In this state, when the horizontal grid 19 is fitted into the notch 12 and the handle 22 of the connector 19 is pushed with a finger or the like to move it in the direction of the horizontal grid, the protrusion 21 passes through the notch 18 of the horizontal grid, as shown in FIG. The front surface of the partition wall 16 is pressed and deformed as shown in FIG.

The pressing protrusion 19 is not limited to the tongue-like shape shown in the figure, but may be a simple bulge-like shape, or may be a ridge-like shape extending in the longitudinal direction.

As described above, according to the present invention, it is only necessary to use small pieces of connectors in the connecting parts of the vertical and horizontal lattices.
Not only does it require less material and can be manufactured at low cost, but it is also easy to assemble because the connection between the vertical lattice and the horizontal lattice is completed by lightly pressing the handle with a finger or the like and sliding the connector. Furthermore, since the horizontal lattice is strongly pressed against the vertical lattice by the pressing protrusions of the connector, it is easier to insert the connector into the guide groove of the vertical lattice, and the locking state of the connector to the vertical lattice is more firmly established. It has the practical effect of not causing rattling in the connecting parts of the grid even when used for sliding doors and doors that are subject to frequent shocks.
