Description

description

The present utility model relates to a spacer joint for rolling grilles, especially to connect the various Types of differently profiled horizontal bars, which the rolling grilles with so-called "see through" form.

As is known, there are joints on the market today which enable this solution by having two or three horizontal joints Connect rods to each other as necessary.

In order to establish this function, the simplest one will be used and the most economical solution used appropriately profiled sheet metal parts, which are used to make the corrugated and the rolling grilles connecting rods to one another. The sheet metal parts mentioned are then made in one operation bent over to the assembly of the rolling grille and closed, said rods lying close to one another being held. It becomes clear that this easy closing process also facilitates opening or "breaking open" and thus makes the safety of said joints questionable, especially in relation to those that make the connection Provide with a third straight rod in which the rear shutter does not simply consist of a bent over Part can exist.

To avoid this disadvantage, other joints were made, those made up of two parallel and

already closed sockets are made by a bracket are connected to each other, which develops at right angles to these, whereby the horizontal, straight and parallel rods are pushed through the sockets.

This type of joint is practical and popular, because it facilitates assembly and is also relatively inexpensive. Nevertheless it shows in its current structure has a disadvantage that can also make safety questionable. The mentioned joint offers with the generally flat one Execution of a quick and easy starting point for cutting pliers or other tools, so the possibility for easy opening or "breaking open" of the rolling grille itself and thus calls into question its function.

In an attempt to avoid this significant disadvantage, other joints of this second type have been made, its The bracket, which connects the two sockets to one another, is of a greater width than the one mentioned above. Indeed, this technical solution achieves a result that gives the rolling grilles greater security, however, it in turn has the disadvantage of the higher manufacturing cost of the joint. Given this Facts is the purpose of this utility model to produce a joint that avoids the above-mentioned disadvantages and at the same time the abandonment of the labor force

facilitated during production, but at the same time a considerable security of the rolling grille overall

$ ensures that it is made with it.

1 Another purpose of this utility model is to

to produce a joint which, thanks to its special structure, can replace a considerable number of the aforementioned joints ! or to connect zvi / ei or three horizontal

I »In this area it is an important purpose of the present-

I the utility model, a joint with a simple structure

These and other purposes, which are made clearer from the description below, are achieved

develop called wall, and have the correspondingly arranged through holes, said wall is also provided on both sides at their free ends with a pair of rearwardly bendable wings, which serve to form a generally cylindrical seat with an axis parallel to the axis of the aforesaid through holes.

Other features and advantages of the present invention emerge more clearly from the following detailed description of a preferred implementation form, which is shown purely by way of example and not of limitation in the accompanying drawings, of which

Figure 1 shows a perspective view of the joint in question;

- Fig. 2 shows a front view of a rolling grille, for which the joint from Figure 1 was used, also in connection with the last rod with the support cheek ;

- Fig. 3 shows the side view of the representation from figure 2.

With reference to the figures mentioned, the joint generally designated by 1 according to the present invention.

This has a front wall 2 of basically elongated rectangular shape, on which the middle part 5 protrudes slightly in relation to the ground plane, so that three different zones 5, 6, 7 are described. Consequently becomes an excellent effect and greater resistance achieved the entire wall, which has two rearwardly bendable wings 6 and 7 on both sides, so that two cylindrical seats 6 'and 7' are formed, which are parallel to each other and for pushing through and receiving serve the rods 8, which form the rolling grille.

In the case of a connection of straight rods, said wings 6 and 7 are provided on the rear side with a bore 6a to accommodate a locking means not visible in the figure, so that an axial displacement between the rods and the joint is avoided. Said joint 1 is provided at its central part 5 with two bent parts 3 and 4 which are parallel to one another and which develop at right angles to the rear in relation to said central part 5 and which partially accommodate the bent wings 6 and 7. The aforementioned bent parts 3 and 4 are provided with bores 3 'and 4 ¹ in order to be able to push through a further middle and straight rod 10 if the joint is to be used for the production of rolling grilles with three elements (see Figure 2).

The assembly of said joints 1 on the elements of the Rolling grilles are easy and quick. When two rods 8 are arranged parallel to each other and in the open ends of the wings 6 and 7 of a joint are inserted, the bending of the wings is then carried out made himself so that they surround the said rods.

After completion of this operation, further horizontal rods 10 can be inserted into the corresponding bores V and 4 'of the bent parts 3 and 4 in a second phase, an operation of decidedly easy going

speed and speed to complete completion of the entire rolling grille.

Referring to Figures 2 and 3, these show the possibility of using the same joint 1 as a fastening 20 between the last rod and the lower support cheek 21 of the rolling grille, with a simple rotation of the joint 1 itself by 180 °. Another possibility exists in the event that rods of smaller dimensions are to be used. In this case it is possible to use the same joint 1 by inserting reducing bushings in the seats 6 ' and 7 *, and a further reducing bushing between said bent parts 3 and 4. The joint in question achieves the desired purposes in this way , especially with regard to the possibility of assembling rolling grilles with any two or three bars, while also maintaining the extensive properties and the guarantee of safety due to the presence of leaves 3 and 4 on the one hand and the extreme robustness on the other hand, so that the insertion of Various types of burglary tools, including those on the lower support cheeks, are rigorously prevented.

The materials used, the shapes and the dimensions can be of practically any kind, depending on the requirements.
