Description

- 1 DESCRIPTION

The present invention relates to the building sector, more particularly closings of building bays and their resistance to burglary, and relates to a bay closing element having improved burglary resistance.

Currently, doors and windows, glazed or not, bay windows or the like always constitute one of the notable weak points of a building in terms of burglary and forced intrusion, in particular in the presence of doors or frame windows in wood, aluminum, polyvinyl chloride or any other suitable material.

One of the common burglary methods consists in inserting a pointed tool into the frame carrying the glazing, then pushing it, passing it between the lateral edge of the glazing and the rebate or groove bottom of the frame, until that it meets the anchoring site of the internal glazing bead, generally the groove receiving the hook for hanging the internal glazing bead holding the glazing and, finally, to disengage or disengage said hook from said groove to release the glazing bead.

By repeating these operations successively for at least three glazing beads of the same glazing (located on three of the four sides of a square or rectangular glazing), it is possible at the end to remove and extract said glazing from said frame.

To prevent this type of break-in, the only solution proposed to date, and which results in a significant improvement in terms of resistance to these break-ins, consists in securing the internal glazing beads in addition to the frame, by screwing at regular intervals.

However, this results in additional repetitive operations, a significant additional cost in labor and a tinkered and unfinished aesthetic appearance.

Document FR-A-2 800 789 discloses constructive solutions which make it possible to provide improved resistance to burglary.

More specifically, this document proposes in particular to provide, on the one hand, a first internal section with U or L section receiving the edge of the filling panel and, on the other hand, a second external section with L section fixed in the frame rebate. The internal profile bears on the external profile under the weight or the push of the filling panel

-2and a notching connection of mutually overlapping areas mechanically assembles the two sections.

However, this catch snap connection is dependent, in the lower part of the frame, on a uniform support of the filling panel over the entire length of the overlapping zones and, on the lateral sides and in the upper part, of an adjusted mounting. precise filling panel in the frame.

However, such constructive imperatives are very difficult to fulfill in series production or else require takeovers or tedious and very costly corrections in terms of manpower.

Thus, the solutions proposed in this prior document, although improving the resistance to burglary, can be greatly improved both in terms of performance (in particular resistance to a push towards the inside of the filling panel), of complexity of implementation and cost price.

The aim of the invention is therefore in particular to improve these aforementioned known solutions.

To this end, the invention relates to a bay closing element, of the opening or fixed type, comprising a peripheral profiled frame and a filling panel, mounted in said frame at the level of a peripheral rebate of the latter, said rabbet being delimited on the outside of the closure element by a first abutment wing formed integrally with the body of the frame profile, said frame further comprising at least one device for locking the filling panel with blocking in position against said first abutment wing, this or each locking device comprising a first profiled part integral with the frame profile and a second profiled part in the form of an angle iron and providing a second abutment wing for the filler panel, opposite the first stop wing, the two profiled parts engaging each other by means of respective notched zones, mutue llement cooperating and formed on corresponding sides of said parts, closing element characterized in that the notched side of the first profiled part defines in cooperation with a part facing the bottom wall of the rebate, a slot-shaped housing for receiving the notched side of the second profiled part, the notched area of the first profiled part facing the bottom wall of the rebate and the

-3 assembly by progressive introduction of the notched side of the second profiled part in the slot-shaped housing effected by successive snaps, with elastic deformation of the notched side of the first profiled part.

Figures 1 to 3 show an opening element 1 of the opening or fixed type, comprising a peripheral profiled frame 2 and a filling panel 3, which is mounted in said frame 2 at a peripheral rebate 4 of this latest. Said rebate 4 is delimited on the outside of the closure element 1 by a first abutment wing 5 formed integrally with the body of the profile 2 'of the frame 2. Said frame 2 further comprises at least one device 6 , 7 for locking the filling panel 3 with locking in position against said first abutment wing 5. This or each locking device 6, 7 comprises a first profiled part 6 secured to the profile 2 'of the frame 2 and a second profiled part 7 in the form of an angle iron and providing a second abutment wing 8 for the filling panel 3, opposite to the first abutment wing 5, the two profiled parts 6 and 7 engaging each other by means of respective notched zones 9, 10 , mutually cooperating and formed on flanks 9 ', 10' corresponding to said parts 6,7.

According to the invention, the notched sidewall 9 'of the first profiled part 6 defines in cooperation with a facing part 11' of the bottom wall 11 of the rebate 4, a housing 12 in the form of a slot for receiving the sidewall notched 10 'of the second profiled part 7, the notched zone 9 of the first profiled part 6 facing the bottom wall 11 of the rebate 4. The mounting by progressive introduction of the notched flank 10' of the second profiled part 7 in the slot-shaped housing 12 is effected by successive snaps, with elastic deformation of the notched side 9 'of the first profiled part 6.

Thanks to the particular provisions of the invention set out above, it is possible to guarantee the establishment of a rigid mechanical connection between the two parts 6 and 7, and therefore a locking in position of the second abutment wing 8 and therefore of the panel. filling 3 against an inward thrust, even when said panel 3 is not in
