Description

SECLJRITE DOOR PANEL
AND METHOD FOR BRIDGING SUCH A PANEL
The invention relates to a security door panel and a method of mounting such a panel.

There were already many embodiments of security doors for habitation (armored or burglar-proof doors) comprising either one or more metal boxes, or one or more shielding sheets associated with one or more exterior coatings based on wood (patents French 2557190, 2450933, 2448617, 2444783, 2411294, 2385877, 2452572, 2463253, 2474091, 2564131, 2567565, 2578284, 2532681). Metal doors have the disadvantages of being unattractive in appearance, of being unsuitable for a wood-based decoration and, finally, of having zero or very low thermal resistance (fire effect). comprising one or more metal sheets and, on each side of them, external wood-based coatings have the disadvantages that they deform when these coatings are subjected to different atmospheres (hygrometry and / or temperature). Various solutions have been proposed to remedy this drawback (French patents 2,571,422 and 2,404,729). In particular French patent 2404729 provides for the presence of metal profiles surrounding the door panel rigidly attached to an interior panel of the door and associated in a floating manner with an exterior panel spaced from the interior panel by an insulating layer. However, such a door does not have the required safety qualities.

The object of the invention is to produce a security door panel, based on wooden panels, allowing numerous possibilities of decoration (such as molding), aesthetic, having excellent stability when subjected on one side and the other at different environments, also having good thermal resistance and, finally, being able to be easily mounted.

The invention also relates to a method of mounting such a panel.

According to the invention, a security door panel I of the type comprising a security plate, in particular of metal sheet, rigidly associated with a first external panel, in particular of wood, or based on wood, by means of rigid association. , in particular by screwing, characterized in that it also comprises a second external panel, in particular of wood, or based on wood, associated with the security plate, on the side opposite to the first panel, by means of floating connections of so that simultaneously the panel has excellent qualities of security and stability in a differential environment.

Also, according to the invention, a method of mounting such a panel is characterized in that first the safety plate is placed on the internal face of the first panel by making the first longitudinal wings cooperate, the first longitudinal returns , the upper transverse wing and the upper transverse return with respectively the first longitudinal rebates, the first longitudinal grooves, the upper transverse rabbet and the upper transverse groove then the second panel is placed on the security plate by making the second longitudinal wings cooperate , the second longitudinal returns, the lower transverse wing and the lower transverse return respectively with the second longitudinal rebates, the second longitudinal grooves, the lower transverse rebate and the lower transverse groove.

The other characteristics and advantages of the invention will emerge from the description which follows with reference to the accompanying drawings in which
Figures 1 and 2 are two schematic views of a security door according to the invention in section along planes respectively horizontal and vertical.

the invention firstly relates to a panel 1 for a security door comprising, in addition to the panel 1 forming a leaf, a frame 2 comprising a rebate 3, hinges 4 and, finally, handles, locks and other accessories (not shown).

The frame 2, the hinges 4, the handles, locks and other accessories are not in themselves directly the subject of the invention and are generally known to those skilled in the art. For these reasons, they are not described further.

The panel 1 is intended to be placed vertically with its large vertical side and its small horizontal side to form the door. This vertical position is used in the following description of "reference position". It is in relation to this reference position "that qualifiers such as" vertical "," transverse "," upper "" lower "are based.

However, it is understood that the panel 1 before mounting on the frame 2 can be placed in a position other than the reference position ", in particular horizontally or vertically lying down.

The panel 1 is of the type comprising a security plate 5, in particular made of metal sheet, rigidly associated with a first exterior panel 6, in particular made of wood, or based on wood, by rigid association means 7, in particular by screwing.

According to the invention, the panel 1 also comprises a second outer panel 8, in particular made of wood, or based on wood, associated with the security plate 5, on the side opposite to the first panel 6, by floating connection means 9 of so that simultaneously the panel has excellent qualities of security and stability in a differential environment.

The safety plate 5 comprises on at least one of its longitudinal edges, in particular vertical and preferably on its two vertical longitudinal edges on one side, a first longitudinal wing II and on the opposite side a second longitudinal wing 12 terminated by a second longitudinal return 13 directed towards the center of the safety plate 5.

In addition, preferably, the first longitudinal wing 11 is terminated by a first longitudinal return 14 directed towards the center of the security plate 5.

In particular, the first and second longitudinal wings 11,12 are at least substantially coplanar and at least substantially perpendicular to the security plate. Thus, as follows from FIG. 1, the wings and returns 11, 12, 13 14 have a flattened U-shaped configuration, the wide core of which is formed by the wings 11, 12 and the short branches are formed by the returns 13 , 14, the safety plate 5 extending in the direction of the branches in the plane of symmetry of this U.

The first longitudinal wing 11 is pierced with holes 15 with which the screws 16 driven in the longitudinal edge 17 of the first panel 6 cooperate.

Naturally, it is possible to replace the screws 16 with other association members, in particular glue, in which case the holes are eliminated.

The first panel 6 has on its longitudinal edge 17 a first longitudinal rebate 18 and, optionally, a first longitudinal groove 19 with which the first longitudinal wing 11 and the first longitudinal return 14 cooperate respectively, these rebate and groove 18.19 being adjacent to the internal face 20 of the first panel 6 situated on the side of the safety plate 5 and spaced from its external face 21, so that on the one hand the external face of the first longitudinal wing 11 is at least substantially coplanar with the external face of the longitudinal edge 17 of the first panel 6 and that, on the other hand, the first longitudinal wing II and the first longitudinal return 14 are normally inaccessible from the external face 21 of the first panel 6.

 The second panel 8 has on its longitudinal edge 22 a second longitudinal rebate 23 and a second longitudinal groove 24 with which the second longitudinal wing 12 and the second longitudinal return 13 respectively cooperate, these return and groove 13, 24 being adjusted to prevent any displacement reciprocal transverse relative of the second panel 8 and the safety plate 5 perpendicular to their common plane and allow reciprocal relative movement in their common plane.

Preferably, the second rebate 23 is adjusted without play or practically without play to the second wing 12. A certain play in the plane of the panel can be produced between the second groove 24 and the second return 13 which does not penetrate to the bottom of groove 24.

The security plate 5 has on one of its transverse edges, in particular the upper 25, an upper transverse wing 26 possibly terminated by an upper transverse return 27 directed towards the center of the security plate 5.

The first panel 6 has on its upper transverse edge 28 an upper rebate 29 and, optionally an upper transverse groove 30, with which the upper transverse wing 26 and the upper transverse return 27 cooperate respectively, these rebate and groove being contiguous to the face internal 20 of the first panel 6 and spaced from its external face 21 so that, on the one hand, the external face of the upper transverse wing 25 is at least substantially coplanar with the external face of the upper transverse edge 2P of the first panel 6 and that, on the other hand, the upper transverse wing 26 and the upper transverse return 27 are normally inaccessible from the external face 20 of the first panel 6.

The upper transverse wing 26 is of limited width, the upper transverse groove 30 being located near the internal face 20 of the first panel 6 so as, on the one hand, to facilitate the mounting of the security plate 5 and, d on the other hand, to avoid excessive deformation of the upper transverse wing 26.

As this results from the above, the upper transverse wing and return 26, 27 form a hook cooperating with the rebate and the groove 29, 30, this cooperation ensuring the relative locking in vertical direction of the safety plate 5 by compared to the first panel 6. However, the invention also includes the case where the safety plate 5 and the first panel 6 are provided with different means making it possible to achieve the same result.

The security plate 5 has on one of its transverse edges, in particular the lower edge 31, a lower transverse wing 32 terminated by a lower transverse return 33 directed towards the center of the security plate 5.

The lower transverse wing 32 is of limited width, the lower transverse groove 36 being located near the internal face 37 of the second panel 8 so as to facilitate the mounting of the second panel 8 on the one hand, and on the other hand, avoid excessive deformation of the lower wing 32.

The security plate 5 is placed. sandwiched between the first and second panels 6, 8 on which they are applied, the first and second panels 6, 8 having at least substantially the same external dimensions, the respectively lower and upper transverse edges 38, 39 of the first and second panels 6, 8 being free.

The second panel 8 is associated with the safety plate 5 on the one hand by resting by gravity on the wing and the lower transverse return 32, 33 of the safety plate 5 preventing their relative relative sliding vertically and downwards and d on the other hand by being held against the safety plate 5 by the cooperation of the second wing 12 and the second return 13 with the second rebate and longitudinal groove 23; 24.

As follows from FIG. 2, the safety plate Sa, in vertical cross section, a general shape of S having a large core formed by the plate proper 5 and two opposite hooks constituted respectively by the wing and the return 26 , 27 on the one hand and the wing and return 32, 33 on the other hand.

Preferably, the first panel 6 is the panel located inward and with which the hinges 4 are associated.

The first panel 6 is also preferably of greater thickness than the second panel 8.

As follows from the above description, the safety plate 5 is invisible since it is sandwiched between the two panels 6,8. The first panel 6 is load-bearing in the sense that it is associated with the frame 2 by the hinges 4 and supports the safety plate 5 which, itself, supports the second panel 8.

Externally and internally the panel 1 has wooden faces. On its longitudinal and vertical edges are the wings II and 12. but these are flush with the edges of the panels 6, 8 and therefore are barely visible.

As follows from the above, the floating connection means 9 are of the type comprising a projection 13, 33, in particular adjoining the security plate 5 cooperating with a groove 24, 36, in particular of the second panel 8, the projection 13 , 33 and the groove 24, 26 being adjusted to each other to prevent any reciprocal transverse relative movement and to allow reciprocal relative movement in the common plane of the security plate 5 and the second panel 8 ;;
In addition, on the one hand, the rigid association means 7 consist partly of wings or peripheral equivalents 11, 26, 27 of the safety plate 5 and partly of rigid association members, such as screws 16 (or glue) cooperating with these wings 11 and, on the other hand, the floating association means 9 consist partly of wings and return or peripheral equivalents 12, 13, 32, 33 of the plate security 5 and part of grooves 24, 36 complementary to the second panel 8.

Finally, it is understood that the floating association means 9 are unidirectional in the plane of the panel 1 but prevent the second panel 8 from being moved away from the security plate 5.

The invention then relates to the method for mounting the panel 1 which has just been described. In this method, first, the safety plate 5 is placed on the internal face 20 of the first panel 6 by making the first wings 11, the first longitudinal returns 141, the upper transverse wing 26 and the upper transverse return 27 cooperate with respectively the first longitudinal rabbets 18, the first longitudinal grooves 19 the upper transverse rabbet 29 and the upper transverse groove 30 then the second panel 8 is placed on the safety plate 5 by making the second longitudinal wings 12 cooperate, the second longitudinal returns, the lower transverse wing 32 and the lower transverse return 33 with respectively the second longitudinal rebates 23, the second longitudinal grooves 24, the lower transverse rebate 32 and the lower transverse groove 33.
