Description

Fixing system comprising blinds metal and a metal plate.

Object of the invention

The object of the present invention is a system for fixing metal blinds (see for example the patent US-A-6,092,581) between the systems of fixation used in commercial establishments, offices and similar, which uses metal plates together with additional parts As main parts.

The present invention is characterized by special configuration of the parts in the fixing system and by the interaction between them so that you get a effective fixing system that prevents the blind from being lifted Even when handled.

The fixing system has a plate metal that contains a series of holes inside the which are fixed tacos and in which some metal bars prominent are housed in holes in the metal blind.

Background of the invention

Until today, the fixing systems of metal shutters have the disadvantage that if the system of fixing, which uses a horizontal cut on the lock, is manipulated, the blind can be raised from the cut towards above, allowing the entry of light and providing this way a view of the inside and outside of the establishment.

Because of all this, the purpose of this invention is the development of a blind fixing system metal that forms a protection system and that in the case of to break, prevent the blind is raised and in this way avoid the entrance of light into the establishment.

Description of the invention

The fixing system that constitutes the object of the invention is a metal plate that works in conjunction with A series of tacos.

The metal plates have holes to through which passes the end of a cue. Plates too feature a series of prominent metal bars, arranged evenly, that they fit into corresponding holes in the blind.

In a first configuration, the holes in the metal plates align with those of the metal blind of way a taco goes through both.

The shape of the holes and the end of the block going through them works so that once the taco is fixed by a padlock, it cannot be removed.

The high security lock is fixed to one of the ends of the block using a hole in the block.

The holes in the metal plate are the frontal projection of the end of the block that passes through the same. Once the cue has passed through the holes of the plate and the blind is turned 90º and locked using the padlock.

Given the proximity of the lock to the wall, it turns out impossible to turn the padlock and the heel at the same time, so that The cue cannot be removed. To reinforce the impossibility of swivel of the block and padlock, the metal plate has wedges prominent who avoid this action.

As a reinforcing element, the metal plate It also features a series of prominent metal bars regularly arranged that are positioned so that they fit with the holes in the metal shutter so that during the Installation procedure are housed in the holes.

As an additional improvement, in order to avoid the need to fit the metal plate on the blind every time which is closed, the metal plate is provided with hinges, such as element to fix it to the wall with hinges.

Preferably, this fixing system of Metal blinds are used in blinds in which the guide protrudes from the facade since they are systems that are installed passing through the guide and the blind at the same time. If there is not one guide through which to pass, the fixing system works from The same way, but it is less safe.

To continue with the development of the systems for fixing metal blinds, there is another procedure that uses the special distribution of several pieces that make up the fixing system: an angular piece of a length that matches with the length of the metal strip blind to which it is welded a hexahedron with a hole made in the center of its length and inside its strips and half pieces of hinges arranged along this angular piece, as shown, in sufficient number to avoid unwanted rotation of the two bars housed in the interior angle of the angular piece and aligned consecutively as well as the spacers between it and the hexahedron to allow them to spin.

For this, in turn these two bars present the remaining half pieces of the hinge welded to them, this bar being previously fitted to avoid contact with the half-hinge welded inside the angular piece.

There are also a series of spikes inserted in holes to align the strips near their ends along of the length of the blind so that the angular piece is attached by one of its wings to a fixed part of the building, such Like the wall

In this case, the wing near it is fixed to the wall with conical head bolts that allow rotation full of the bar inside the angular piece while the other wing of the angular piece fits inside the guide of the blind on its outer wing.

This special construction of the set allows that the rod of a conventional prismatic lock passes through the hole in the hexahedron, fixing the bars at this end and by the hinges, up to the limit of protection provided by the further hexahedron, thus making the fixation tested of manipulations.

Another development of the invention is the special distribution of several pieces that form the system of fixing: a double metal plate of the same length as the metal strip blind, so that the outer side of both presents a perforated hexahedron welded to it in its center and the hinge half pieces superimposed and welded to this bar higher, in sufficient numbers to prevent unwanted rotation of the two bars, which are longitudinally symmetrical and with gaps centrals that separate them from the hexahedron, allowing them to rotate. By therefore, these two smaller bars present the other half pieces of the hinge welded to them successively.

These smaller bars are also provided with a series of pins inserted in holes for double align the strips near their opposite ends and in a coplanar distribution and that can reach the total length of the blind so that the outer metal plate on which they fold is fastened with screws to another similar metal plate inside the central guide in the pillar between the two Blinds.

This special construction of the set allows that the rod of a conventional prismatic lock passes through the hole in the hexahedron, fixing the metal plates by this end and hinges to the limit of protection provided by the farthest hexahedron, doing this way tamperproof fixing.

Preferred embodiment of the invention

Given the figures indicated above, to a preferred embodiment of the invention and an explanation of the figures.

Figure 1 shows the metal plate (1). The Metal plate (1) has a rectangular shape and a series of holes (2) through which a plug (4) can pass (see Figure 2).

The metal plate (1) presents a series of bars (3) welded to the metal plate. These bars are located  on the face closest to the metal shutter and avoid any movement of the whole, providing greater rigidity to the same.

To achieve this, the metal blind presents a series of holes that match the bars prominent metal (3) on the metal plate so that the Bars (3) fit into the holes.

Once set, the rotation of the block / padlock system it is prevented by the proximity of the wall and the wedges (8) that protrude outward from the metal plate, which prevent the mount turn.

Figure 2 shows the block (4) used with a prominent bar (4.2) at whose free end there are spikes (4.3) arranged transversely. It also has a hole (4.1) a through which the padlock passes.

The shape of the holes (2) coincides with the projection of the end of the block (4) passing through it.

Once the cue is inserted into the holes (2) in the metal plate (1) and in the holes matching metal blinds, rotates and locks a lock on the hole (4.1). Given the proximity of the lock to the wall, it turns out impossible to turn the block and release the set. This situation is reinforced by the distribution of prominent wedges (8) indicated above that prevent the rotation of the set padlock / cue.

In order to have to fix and remove continuously the metal plate every time the blind is open and closed, the plate has been modified, providing a plate articulated (5), as shown in Figure 3.

This articulated plate (3) presents a series of hinges (6) arranged regularly to match the housings (5.1) to facilitate the folding of the plate (5).

In the same way, the plate presents a series of prominent metal bars (7) that fit inside the holes in the metal blind. It also features wedges prominent (8) that prevent the rotation of the padlock / heel assembly, a fixed time

To continue with the development of the systems for fixing metal blinds, there is another procedure that uses the special distribution of several pieces that make up the fixing system characterized by an angular piece (9) a which is welded a hexahedron (10) with a hole (10.1) for the insertion of a prismatic lock (not shown) and the consecutive alignment of the semi-hinges and the two plates metallic (11) which in turn have other semi-hinges complementary welded to them, with these metal plates previously fixed (11) free of contact with the angular piece (9) during its 90º turn.

The metal plates (11) have a series of pins (11.1) that are inserted into the strips (12) so that the angular piece (9) is attached to a fixed part (13) of the building with conical head bolts (14) and fixed to the blind guide (fifteen).

Another development of the invention (Figure 6) presents a double metal plate (16 and 17) so that the plate metallic (16) has a hexahedron (18), with a hole (18.1), soldier to it and the half pieces of the hinges in a number enough to avoid unwanted twist of two bars longitudinally symmetrical (19) to which the others are welded semi-pieces of the hinges and having central holes (19.1) that separate them from the hexahedron (18) and a series of spikes (19.2) that they pass through a series of holes (16.1, 17.1) opposite to the metal plates (16, 17) so that these metal plates (16, 17) are held together, leaving the central guide (20) on the pillar of both blinds in half.
