Description

REMOVABLE AND SELF-LOCKING SECURITY DEVICE AVOIDING ANY INTRUSION THROUGH AN OPENING PROVIDED FOR IN A WALL

The present invention relates to a removable and self-locking security device preventing any intrusion through an opening provided in a wall.

A device of this type is described in French patent application No. 2,618,180 of the Applicant.

This known device comprises at least one male element and one female element intended to be mounted transversely with respect to said opening while being coupled so as to form a bar going from one side of the opening to the opposite side, and at least a module carrying at least one protective bar, said module being adapted to cooperate with said bar and to achieve mutual locking with it, said bar being of rectangular polygonal section and the module being a suitable L-shaped angle to come to fit on said bar.

However, it is mentioned in the aforementioned patent application that, instead of using an L-shaped angle iron, a U-shaped profile could be used without the

Applicant drew at the time the advantages of such a structure.

The device according to the invention uses such a U-shaped profile.

In the known device, the angles are juxtapo¬ ed end to end and a flat head axis system 92 and wool 25 provides a safety lock. To prevent any lateral movement of the angles, a lock is provided which cooperates both with the male element 6 and with a stud 22 depending on the angle 14 and penetrating into the male element 6, which implies that the lock 60 must be located in the extreme lateral position.

These layout necessities no longer exist according to the invention thanks to the use of a U-shaped module serving as a blocking module.

According to the invention, the wing of the U-shaped section of the blocking module intended to be located on the inside of the opening, when it is equipped with the device, has a cut out opposite a solid bar. to the wing opposite, and said cutout is adapted to come in concordan¬ with a similar cutout made in the adjacent wall of the bar on which the blocking module is fitted, the two cutouts in concordance being adapted to receive an extractable lock, protected on the outside by said bar.

Generally, the device according to the invention further comprises at least one complementary module formed by a U-shaped profile carrying at least one bar, said complementary module being adapted to fit onto said bar.

Advantageously, the blocking module comprises at least at one of its ends an area of the same geometry, but of larger section, adapted to cover the adjacent end part of the U-shaped section of the complementary module.

In the device which is the subject of the aforementioned patent application, the female element was provided with a series of buttonholes 18 and 30 of complicated shape requiring laser machining. It was also necessary to make a rigorous parallelism between the pins on each face of the angle as well as between the receiving buttonholes provided in the female element, which implied precision manufacturing, hardly compatible with the rusticity of the product that the 'we were looking for.

According to the invention, the multiple buttonholes of complex geometry are eliminated and replaced by a considerably reduced number of holes whose edge does not define any re-entrant angle, which can be machined using simple means. These holes, for example oblong, round or rectangular, are adapted to cooperate with a tongue formed in the complementary module to block in one direction the axial sliding of the complementary module relative to the bar. The invention will be better understood on reading the description below made with reference to the accompanying drawings in which: FIG. 1 shows an opening equipped with the device according to the invention, seen from the outside of the wall in which this opening is made,

As appears from the drawings, and in particular from FIG. 13 _} the modular device according to the invention, in the illustrated version, comprises two bars designated as a whole by 1 and 1 '. The bar 1 is constituted by a male element 2 and a female element 3- The male element 2 is capable of sliding in the female element 3- The male element 2 (figure 7) has a light 4 and the female element 3 (FIG. 5) a bore 5 in the axis of the light 4. A screw 6 (FIG. 8) with a hollow head which can be maneuvered using a hexagonal key, called a CHC screw, mounted from the outside of the hole 5 penetrates into the lumen 4 and cooperates with a non-visible nut placed inside the male element 2. The bar 1 therefore constitutes a telescopic assembly the length of which can be varied by making the male element more or less penetrate in the female element and immobilizing the two elements relative to each other by screwing the CHC screw. It is understood that this adjustment in length and this immobilization are done after placing the free ends of the elements 2 and 3 in recesses provided for this purpose in the frame 9 of the opening to be protected. These recesses are advantageously each provided with a sleeve 7a, 7b adapted to receive respectively the free end of the emelle element 3 and that of the male element 2.

The bar 1 'is made in the same way as the bar 1, namely a male element 2' and a female element 3 '•

The modular device, in the illustrated version, further comprises two complementary modules 10a, 10b, adapted to fit each on the bars 1 and the. The module 10a consists of two U-shaped sections, 11a and 12a, secured to two bars 13- At their end opposite to the frame 9 *. the profiles 11a and 12a have a tongue 14a (FIG. 9) and 15a, respectively. The module 10b has the same characteristics as the module 10a and its components are designated by the same references, but accompanied by the index b instead of a.

The female element 3 of the bar 1 has on its upper face two oblong cutouts 16a and lόb (Figure 6). The same applies to the bar 1 'which has two oblong cuts 17a and 17b. The cutout lόa of the bar 1 is intended to accommodate the tongue 14a provided on the profile lia. Similarly, the cutout 17a of the bar 1a, is intended to receive a tongue 15a provided in the same way for the section 12a. Similarly, the cut lόb is adapted to accommodate the tongue 14b of the profile 11b and the cut 17b, the tongue 15b of the profile 12b.

The meeting of the additional modules 10a, 10b on the bars 1 and 1 'is carried out as follows: first of all, the tongues 14a and 15a of the module 10a are placed in correspondence with the cutouts lόa and 17a of the bars 1 and the, so as to make them come into engagement, and the entire complementary module 10a is made to slide in the direction of the sleeves 7a, 8a with penetration of the ends of the profiles 11a, 12a of said complementary module into said sleeves 7a, 8a . The module 10b is mounted in the same way but by making the end of the profiles 11b and 12b opposite the tongues 14bj 15t penetrate into the sleeves 7b, 8b. The blocking module which will now be described ensures locking of the assembly. This module, designated as a whole by l8, consists of two U-shaped sections, 19 (FIG. 11) and 20, secured to two bars 13. Each section 19j 20, has, at the end, a part of the same geometry but of larger section. , called "flare", respectively 19a, 19b, 20a, 20b. On the wing of the profiles 19, 20, facing the inside of the opening equipped with the device according to the invention, an oblong cutout 21 (FIG. 11), 22 is provided, facing a ba-rreau 13 secured to the other wing of the profile (Figure 12). Corresponding cutouts 23 (Figure 5), 24 are provided in the female element 3 of the bars 1, l ', so that when the sections 19 are fitted together _. 20 of the blocking module on the bars 1, l ', the cutouts 21, 22 come respectively opposite the cutouts 23, 24- The flares 19a, 19b, 20a, 20b on their side cover the ends profiles 11a, 11b, 12a, 12b of the additional modules. In the facing cuts 21, 23 on the one hand, 22, 24 on the other hand, it is possible to introduce an extractable lock 25 (FIG. 12), which is locked in place at the using a key, as described below in more detail.

The disassembly of the device is done in the reverse order of the operations set out above, that is to say opening and extracting the locks 25 _. removal by vertical traction directed upwards of the blocking module 18, extraction of one of the complementary modules 10a by axial traction away from the sleeves 7a, 8a with which the sections 11a, 12a of this complementary module are engaged , then vertical traction directed towards the top of the module 10a, extraction of the second complementary module 10b by proceeding in the same way, unlocking of the male element 2 and 2 'relative to the female element 3 and 3', sliding of the 'male element 2, 2' in the female element 3, 3 'to reduce the length of the bars, and extraction of the bars 1 and 1' from the sleeves 7a, 7b and 8a, 8b of the frame. If we now examine Figure 12, we see that a sheath 26 is secured to the edge of the cutout 23 at one of its ends 27 flared in a tulip, the other end 28 of the sheath 26 is free. The cutout 21 of the profile 19 of the complementary module 18 being opposite the cutout 23 of the female element 3 of the bar 1, it is possible to introduce the body of the lock 25 into the sheath 26. A key 29 makes it possible to operate the bolt 30 of the lock which, when it projects, prevents the extraction of the lock 25 by coming into abutment at the center of the edge 28 of the sheath 26.

As appears from the preceding description, the constituent elements of the device according to the invention are a simple structure requiring no sophisticated machining and the assembly and disassembly of the device does not require any particular technicality and can be executed in a few minutes. In the embodiment of FIG. 1, two complementary modules 10a and 10b are used forming complementary end modules, and a blocking module 18. When it comes to equipping large openings, it can be necessary to have recourse to intermediate complementary modules which have a structure inspired both by that of the end complementary modules and that of the blocking module.

Like the U-shaped profiles of the end complementary modules, those of the intermediate complementary modules do not have a cutout for the passage of a lock, but they include a tongue system adapted to cooperate with cutouts provided for this purpose in the elements. females 3, 3 '•

Like the U-shaped profiles of the blocking module, the intermediate complementary modules have a flare at the end but at only one of their ends.

These characteristics emerge from Figure 14 where we see a U-shaped section 31a belonging to an intermediate module complementary 33 (Figure 15) and having a flare 35a at one of its ends. On the upper face of the profile 31 are cut two tongues 36 and 37 adapted to cooperate with cutouts provided in the female element 3 and similar to the cutouts lόa, lόb.

The cutout creating the tongue 37 is covered with a welded pad 38 preventing access to said tongue from the outside of the section 31a. The cutout creating the tongue 36 does not need to be protected in this way because it is covered by a flaring of the blocking module. The use of intermediai¬ res complementary modules is shown in Figure 15 which shows very schematically the relative position of the different modules. As in the case of the embodiment described with reference to FIGS. 1 to 13, one of the ends of the sections 11a and 11b of the complementary end modules penetrate into the sleeves 7a, 7b. The opposite end of the sections 11a and 11b is covered by the flaring 35a, 35b of the sections 31a, 31b of the intermediate complementary modules 33 _. 34 _*

The end of the sections 31a, 31b devoid of ¹ flare is itself covered by the flares 19a, 19b of the section 19 of the blocking module. The complementary end profiles 11a, 11b and the intermediate complementary profiles 31a, 31b are engaged with the female element 3 of the bar 1 by penetration of their tongues in the corresponding cutouts of said female element. The whole is locked by the section 19 of the blocking element and its lock 25.

The same applies to the sections 12a and 12b of the end complementary modules, of the sections 32a and 32b of the intermediate complementary modules and of the section 20 of the blocking module. It is understood that the invention is not limited to the embodiments described and shown. In particular, the device could comprise only an additional module in which case the blocking module would not occupy a central position but a lateral position and it would only be provided with a flare on the side of the complementary module.

Furthermore, the device could use more than two bars 1 and 1 ′, for very high openings and the modules include a corresponding number of U-shaped profiles.

In addition, instead of penetrating into sleeves 7a, 7b, 8a, 8b included in the thickness of the wall whose opening is protected according to the invention, the bars 1 and l 'could be mounted as shown in the figures 7 and 12 of the aforementioned French patent application No. 2 618 180, both on the inside and outside of the wall.
