Description

[Detailed description of the invention] This invention relates to a lattice body useful as gates, fences, handrails, etc., and its purpose is to connect horizontal and vertical bars made of aluminum with fastening fittings such as screws and rivets. The object of the present invention is to provide a lattice body that is firmly fixed without using any lattice, is inexpensive, and is rich in aesthetic appearance.

To specifically explain this proposal using drawings, horizontal bars 1, 1 arranged at the upper and lower portions, vertical bars 2, 2...
In fixing the horizontal bars 1, 1..., the horizontal bars 1, 1, . are provided with protrusions 4, 4 which are taller than the wall thickness of the protruding part 3, and cut grooves 5, 5... are provided in the protruding part 3 of the horizontal bar 1 at the positions where the protrusions 4, 4 of the vertical bar 2 come into contact. The protrusions 4, 4 of the vertical bar 2 are fitted into the notch grooves 5, 5 of the horizontal bar 1, and the protrusions 4, 4 that fit into the notch grooves 5, 5 are bent to form the protruding portion of the horizontal bar 1. The blindfold member 6 is fitted and fixed in the opening of the horizontal beam.

In the figure, 7 represents a vertical girdle, 8 represents an embedded screw, and 9 represents a screw hole.

The present invention has the above-mentioned configuration, in which a protruding part 3 is formed on the horizontal bar 1 with an open outer surface, notch grooves 5, 5... are bored in the protruding part, and a protruding part is formed on one side of the vertical bar 2, 2... Protrusions 4, 4 are provided, and the protrusions 4, 4 of the vertical bar 2 are fitted into the notch grooves 5, 5 of the horizontal bar 1, and the protrusions 4 are fitted into the notch grooves 5.
It is possible to firmly fix the horizontal beam and the vertical beam without using fastening fittings such as screws or rivets, and after fixing both the beams, a blinding member 6 is applied to the opening of the horizontal beam 1. , the curved parts of the protrusions 4, 4... can be shaded to create an aesthetically pleasing finish.The manufacturing process is to make the horizontal and vertical bars using extruded aluminum, press cut them at predetermined positions, It is suitable for mass production because it is sufficient to fit the horizontal and vertical bars together, press the protrusions, and insert a blinding member made of synthetic resin or aluminum molded material into the opening of the horizontal bar. The effect is remarkable.
