Abstract

The componible window cross-bar (Fig. 1) has a function of protection against breaking into the apartments through windows or some other apertures. To assemble the cross-bar's elements, and mounting to the aperture, no welding, riveting or screws are necessary to be applied. The cross-bar is composed of prefabricated elements (1 to 5) (Fig. 2) specially perforated and shaped in order to insure, once crossed, the inseparable joint. It is due to a particular indent (7) on the perforations (6) (Fig. 3), which once closing the bar's angle, are going to be overlapped by making a strong clinch. The mounting to the wall aperture can be done by using the particular fastening joint group (Fig. 9 and 12) composed of the metal spike (9) spike guide (10) and clasp prolongation tube (8) or using the "pull tight screw group" (Fig. 11). The cross-bar can be also mounted by attaching to the window frame as shown in the Figure.

Description

MODULARLY ASSEMBLY WINDOW GRILL

Technical area

The invention relates to protective grilles for windows and other openings.

The state of the art

The well-known method of making windows and other openings is in accordance with the client's wishes, because each product is made individually. Welding ensures strength and rigidity of the structure. Fastening to the window is made with the help of different screws and bolts.

Disclosure of the Invention

This problem has been known for a long time and has been tried in many ways. The task is always the same, to provide adequate protection for windows and other openings with the help of protective bars. The most important things are: security, decoration and low production costs. The modular assembly system is used to secure openings of different dimensions.

The purpose of the present invention is to provide a simple, safe, inexpensive and aesthetically pleasing grille system designed to protect against burglary through windows and other openings. The job is to create a simple grid system that can be assembled and installed by non-professionals and non-professionals using a non-professional tool.

In order to accomplish this task and meet these requirements, assembly is performed using mounting elements and without welding.

The invention will now be described by way of example with reference to the drawings, where:

Figure 1 shows the finished and mounted grille.

Figure 2 shows the different types of crossbars used.

Figure 9 shows an individual fastening system consisting of a wall wedge, a wedge guide, and a clamp extension tube.

Figure 10 shows the attachment system when the grille is mounted on the window frame.

Figure 11 shows the attachment of the grille when it is attached to the encircling wall using a self-locking screw.

12 shows a fastening joint system using a special rectangular curved crossbar 5, FIG. 2.

The grille, Fig. 1, consists of specially designed and perforated cross sections 1-5, Fig. 2, and the special fastening joints shown in Figs. 9, 10, 11 and 12. It can be mounted on the window opening by attaching to the surrounding wall, but to the window frame.

The lattice consists of intersecting cross sections. For this purpose, special sections 6, with special triangular teeth 7, Figure 7, are located on the cross sections 2, 3 and 4, Figure 2.

The number and dimensions of each bar used depend on the dimensions of the opening. Figures 3, 4 and 5 show the way and method of crossing and closing the cross bars. First, the crosses intersect at the points of the sections in i.e. open position (open angle position), Figures 4, 5 and 7.

After the bars are crossed and the entire structure is pressed in the direction of the arrows, the bars rotate in the direction of the arrows in Figures 5 and 7. This operation ensures that the completed structure is closed. The teeth 7 coincide and in this position the bars are in an inseparable joint. The grille is now in i.e. closed or closed position,

-3246-Ρ047 / 99 Figure 8.

At the ends of the crossbars, which are now parallel, Figures 1 and 8, fit a clamp extension tube 8, Figures 1 and 9. The grille structure is now ready to be mounted on the window opening.

This can be accomplished by attaching to the encircling wall by using a special fastening group consisting of a clamped extension tube 8, a metal wedge 9, and a wedge guide 10, Figure 9. The clamping extension tube 8 is inserted at the parallel ends of the crossbars, then followed by a wedge 9, Fig. 9, which is inserted into a hole in the wall, and a guide for a wedge 10 which is inserted between the two said parallel portions 2 and 3.

To secure the grille to the encircling wall with a self-locking screw, the special system in Figure 11 is used. The self-locking screw is inserted into the hole in the wall. The tubular insert 14 is screwed onto the driven bolt, followed by the perforated conical insert 15, and all fixed with a nut.

The grille can also be fitted by attaching to the window frame, Figure 10. It is made by using a clamp extension tube 8, with an opening for the passage of a screw with a split head 11, spacer 12 and guide 10, figure 9.

Crossbar 5, Figure 2, is an angular crossbar (non-intersecting crossbar), particularly perpendicularly curved, so that it cannot be pulled out. The fixing group described above is used for its attachment, as shown in Figure 12.
