Description

[Detailed Description of the Invention] The present invention relates to the structure of a lattice body, and mainly relates to the structure of gates, fences, etc. made of metal members such as aluminum.

Conventionally, in this type of lattice body, when arranging a large number of lattice beams on a frame material, the ends of the lattice beams were generally fixed to the frame material by methods such as welding or screwing. This method not only requires skill or requires a large number of parts, resulting in poor workability, but also has an unsightly appearance as welded parts, screws, etc. are visible.

In view of the above-mentioned problems, the present invention simplifies the structure of the lattice body, and also allows easy assembly work.
Moreover, its rigidity is aimed at proposing a large lattice body.

The present invention will be described below with reference to embodiments shown in the drawings.

The embodiments shown in the drawings show examples in which the lattice body of the present invention is applied to aluminum gates, and FIGS. 1 to 3 show the first embodiment, and FIGS. 4 to 6 show the second embodiment to fourth embodiment are shown.

The gate X has a rectangular frame 1 with a pair of horizontal frames 3, 3 placed above and below the top and bottom of a pair of vertical frames 2, 2 spaced apart from each other by a predetermined distance on the left and right. It has a structure in which a large number of hollow vertical lattice bars 4, 4, . . . are arranged between 3, 3.

A bulge 5 is integrally formed in the longitudinal direction of each of the pair of horizontal frame members 3, 3 constituting the frame 1 on the inner opposing surfaces thereof, and the ends of the hollow vertical lattice beams 4 are integrally formed. By making a pair of cut grooves 6, 6 at intervals that allow the parts to fit together, to a depth that reaches the base of the bulging part 5,
A large number of mounting protrusions 7, 7... are formed. 8 indicates a bishole.

The vertical lattice beam 4 is a square pipe, and the ends of the pair of constituent walls 4a, 4a are cut into the pair of cut grooves 6,
6, the remaining pair of constituent walls 4b, 4b of the vertical lattice 4 are each provided with two inner protrusions 9, for a total of four. The distance between the inner protrusions 9 in the front-rear direction is the same as or slightly larger than the width of the mounting protrusion 7 described above, and when fitted, the mounting protrusion 7 is held between the inner protrusions 9 as shown in FIG. That is, the tip of the inner protrusion 9 at the end of the vertical lattice 4 and the inner protrusion 9
The mounting protrusion 7 is surrounded by the pair of constituent walls 4a, 4a which do not have any.

In this way, the upper and lower horizontal frame members 3, 3 fitted with a large number of vertical lattice members 4, 4... are connected to the left and right vertical frame members 2,
2, and screws 10 are screwed into the screw holes 8 from the outside to form the gate X.

FIG. 4 shows a second embodiment in which the vertical lattice bars 4 are elliptical in cross section. Vertical lattice 4
Two inner protrusions 9 are provided on each of the front and rear sides that protrude inwardly along the longer diameter direction. Further, the cut grooves 6 formed in the bulging portions 5 of the horizontal frame beams 3 are curved to correspond to the elliptical vertical lattice beams 4.

Figure 5 shows a third model using relatively thin vertical lattice bars 4.
An example is shown in which the internal protrusions 9 of the vertical lattice beams are formed into a tapered chevron shape. Such a shape makes it easy to fit the mounting protrusion 7 and the vertical lattice 4, which is convenient.

FIG. 6 shows a fourth embodiment in which all constituent walls 4a, 4a, 4 of the square pipe-shaped vertical lattice 4
The chevron-shaped inner protrusion 9 protruding inward from b, 4b is 2
It is formed one by one. For this reason, the cut groove 6 is widened to enable fitting.

In this embodiment, the vertical frame members 2, horizontal frame members 3, and vertical lattice bars 4 are all extruded.

In this example, the mounting protrusion was formed on the horizontal frame material, but
This is because the frame has vertical lattice bars, and if the frame has horizontal lattice bars, then of course the mounting projections will be formed on the vertical frame members. Further, it goes without saying that the specific shapes and configurations of each member can be variously changed within the scope of the utility model registration claims.

Since the present invention is as described above, when assembling the frame material and the lattice lattice, it is only necessary to cut grooves at appropriate positions on the bulging part of the frame material and fit the ends of the lattice lattice. It becomes easy. In addition, the appearance is improved because welded parts, screws, etc. are not exposed as in the conventional case.

Furthermore, since the internal protrusions that protrude inward from the lattice beams are formed, the lattice beams themselves are reinforced, and since the internal protrusions of the lattice beams are fitted to sandwich the mounting protrusions of the frame material, twisting, etc. This is a practically useful idea, as it is strong against external forces and greatly increases the rigidity of the grid.
