Abstract

The reinforcement and security bar consists of a hollow, polygonal section bar (1) with its upper section (2) folded over to form a slot which receives inverted L-shaped brackets (5) designed to engage with existing slots, e.g. aeration holes, in the shutter (P). The brackets have elongated slots to receive fixings in the form of bolts (6) with washers (8) nuts (7) and locking rings (9). The two ends of the bar are equipped with sliding bolts (10) to engage with holes in the side walls, e.g. of a window opening, and it can also have a bracket (14,15) in the middle to lock a long bolt. The bar and its accessories are pref. made of stainless steel, Al, epoxy, or polyester. USE/ADVANTAGE - Fixes on inside of shutter to give added security. Reduces risk of break-in by preventing shutter from being lifted off hinges or force open.

Description

 The present invention relates to a removable safety reinforcement and locking device for blinds and shutters.

 The invention relates to the technical field of fixed or mobile closing elements of the louver type, shutters, hatches and the like, more particularly to the sector of screens and security closing devices making it possible to avoid break-ins.

 The use of shutters and shutters to close doors and windows is widespread, the main problem being to effectively fight against the rapid intervention of burglars; in fact, they only need a few seconds to break a common closure. from the outside, using suitable tools, whether they be shutters or shutters. The majority of current safety devices do not prevent the opening of a leaf or the unlocking of the cremone bolt after hooking the spanish on louvers or shutters which have gills or ventilation slots.

 The invention makes it possible to remedy these major drawbacks and to propose a simple, light and removable device.

Its implementation is facilitated by the use of gills or external ventilation slots on the blades or leaves of the shutters and shutters and eliminates all the always delicate modification work on old models.

 The present invention also aims to solve the technical problem of adaptability to different types of shutters and shutters and adjustment to openings with standard dimensions or not, with the possibility of adjustment according to the tolerances of masonry work.

 It consists of a device comprising a receiving bar which is placed horizontally across the louvers or shutters by hanging in the louvers or interior walls, to provide both reinforcement and locking of the closing elements.

 The accompanying drawings illustrate the invention in a non-limiting manner, and should allow a better understanding of it.

 Figure 1 shows a schematic perspective view of a shutter leaf seen from the inside and equipped with a reinforcement and locking device according to the present invention.

 Figure 2 shows an enlarged sectional view of the device installed in the support position, on the one hand in the hearing of the leaf, on the other hand, resting on the wall support.

 Figure 3 shows a schematic perspective view showing the components of the device.

 Figures 4,5 and 6 show in detail the different forms of accessories that can be installed on the receiving bar depending on the variants selected.

 Figure 7 shows a sectional view of a variant of the device-device in the horizontal support position.

 The receiving bar consists of a polygonal tubular profile with an open edge (1), on which is welded a reinforcement slide with uneven wings (2). This gives a reconstituted profile which has a longitudinal opening (3) over all the length of the receiving bar. This opening (3) makes it possible to receive the anchoring brackets (5) locked in position in the louvers or shutters on the one hand, and fixed on the other hand on the bar. receiving (1.2.3) by screw (6), shaped nut (7), washer (8) and rod (9).

The reception bar (1.2.3.) Is adjustable in length thanks to two tubes (4) with adjustment lights which slide inside the reception bar (1.2.3) and are locked in position by the assembly (5.6.7.8.9)
The device is locked by locking pins (10) which slide in the guide rails (11) with locking screws in position (12) and stop screws (13). The target -tes (10) are positioned under the wall supports (16) and ensure the vertical locking of the device.

A cremone stopper bracket (14) is arranged in an axial position on the receiving bar (1,2,3) and fixed by the clamping device
(6,7,8,9j identical to the tightening of the anchor brackets (5).
cremone bolt stop is adjustable from right to left on the bar, and from before
behind by the light which allows the sliding of the clamping device (6,7,8,9).

Immobilization of the cremone bolt is ensured by a locking button
(15) which keeps the cremone bolt in the closed position against its stops.

A wall support (16) is used at each end to lift the support bar (1,2,3) in a horizontal position. This wall support (16) can be made of metal and have different non-limiting shapes
(in folded flat iron, angle iron, C profile, UPN profile or similar.

 This wall support (16) will be fixed to the wall with two or four screws (17) depending on the size of the opening to be protected. This support (16) has a double function, since the receiving bar (1,2,3 ) rests on its upper part: if an action is taken on the bar to lift it, it is locked in position under the wall supports (16) by the locking bolts (10).

 The reception bar (1,2,3) was invented to receive accessories-very different in their function, but standardized: they can be adjusted on the bar and immobilize them in any position quickly and easily by simple blocking or screw release (6).

 This bar (1,2,3) makes it possible to protect old louvers equipped with leaves with ventilation louvers without the need to make modifications, using only the original louvers.

-. The reception bar is an innovation compared to all the devices designed from the bar to date,
- in the sense that it is adaptable to several different types of blinds or shutters by the possibility of adjusting the spacing on the bar and on the brackets.

 -in the sense that it is adjustable to several opening dimensions by 4 sliding tubes which make it possible to adjust the length of the bar.

 - in the sense that it is light and resistant because it is made of thin sheet metal and in the form of a very resistant reconstituted profile and of a weight much lower than the bar profile of standard commerce.

 This set of bars and accessories will come in the form of a kit to install yourself, in which the only real work will be the installation of two wall supports (16) with the screws (17).

The ergonomics of this bar has been specially studied to allow
easy handling and the rounded shape of the slide (2) prevents any possibility of abrasions.

 Its thin sheet construction has considerably reduced its weight and facilitates handling by the elderly.

Its resistance has been tested with a weighing system: it is more resistant
-as much as standard bar profiles over 40%.

The reception bar (1,2,3) is presented as a support of the type
universal in the sense that it was invented to receive accessories
different in their own function, but having in common a possibility
to slide and be adjusted quickly and easily on it.

This reception bar (1,2,3) may have different uses
-referential or complementary depending on the equipment that is there
will install: -with the anchoring brackets (5): reinforcement and anti-unhooking.

-with stop brackets: blocking and locking of the creat
-mone.

-with brackets fitted with bars: anti-ef provision
-fraction.

-with brackets supporting vibration detectors or
shock or presence: intrusion detection.

The inventor having vocation to promote articles of locksmithing and more particularly accessories of protection of the typical habitat:
- courtyard doors
- bodyguard
- protection of basement windows
- security bar
- installation of shutters and shutters,
he was led to design a safety device for shutters and
shutters.

He hopes to be able to develop it at the regional level at first and if the product meets a need well, he will study the possibility
distribution in the national network.
