Description
Dispositif de Protection du cylindre de sûreté d'une serrure à larder.Protection device for the safety cylinder of a larder lock.
L'invention concerne un dispositif de protection du cylindre de sûreté d'une serrure à larder, ladite serrure à larder étant montée dans une creusure du chant d'une porte et comportant un passage pour un cylindre de sûreté.The invention relates to a device for protecting the safety cylinder of a larder lock, said larder lock being mounted in a recess in the edge of a door and comprising a passage for a safety cylinder.
Pour améliorer la résistance aux tentatives de forçage, en particulier par chocs frontaux sur le cylindre de sûreté, on a proposé (FR-A-2.623.231) d'entourer le cylindre par une pièce métallique massive en forme d'étrier disposée dans un passage de la porte avant le montage de la serrure puis du cylindre de sûreté.To improve the resistance to forcing attempts, in particular by frontal impact on the safety cylinder, it has been proposed (FR-A-2.623.231) to surround the cylinder with a massive metallic piece in the shape of a stirrup arranged in a passage of the door before mounting the lock and then the safety cylinder.
Cette pièce métallique massive présente cependant divers inconvénients. En premier lieu, elle doit être logée préalablement dans le passage de la porte, dans une position déterminée, avant de monter et fixer la serrure sur la porte, puis de monter le cylindre et le fixer par une vis de chant.This massive metal part however has various drawbacks. Firstly, it must be housed beforehand in the passage of the door, in a determined position, before mounting and fixing the lock on the door, then mounting the cylinder and fixing it with a song screw.
Ce montage est malaisé mais, surtout, la pièce métallique n'est maintenue que par la vis de fixation du cylindre de sécurité fixée sur la têtière. En outre, l'écartement entre les branches de l'étrier peut permettre le passage d'outils. This assembly is difficult but, above all, the metal part is only held in place by the security cylinder fixing screw fixed to the headrest. In addition, the spacing between the legs of the stirrup can allow the passage of tools.
La présente invention vise en conséquence à fournir un nouveau dispositif de protection du type cité en référence qui ne présente pas les inconvénients des dispositifs connus.The present invention therefore aims to provide a new protection device of the type cited in reference which does not have the drawbacks of known devices.
A cet effet, le dispositif de protection selon l'invention est caractérisé en ce qu'il comprend une pièce frontale externe massive munie d'un alésage de passage du cylindre de sécurité et une plaque de fixation arrière reliée à ladite pièce frontale par au moins deux vis dont au moins une traverse le palâtre de la serrure.To this end, the protection device according to the invention is characterized in that it comprises a massive external front piece provided with a bore for the passage of the safety cylinder and a rear fixing plate connected to said front piece by at least two screws, at least one of which passes through the lock panel.
Le dispositif selon l'invention peut être monté après fixation successive de la serrure et du cylindre de sécurité, ce qui est plus commode que le montage préalable prévu dans FR-A2.623.231. En outre, le dispositif de protection selon l'invention est solidaire de la serrure, ce qui renforce la résistance d'ensemble. Les deux parties du dispositif de protection, en particulier la partie frontale, sont serrées contre le palâtre de la serrure, ce qui interdit le passage d'outils de forçage.The device according to the invention can be mounted after successive fixing of the lock and of the security cylinder, which is more convenient than the prior mounting provided in FR-A2.623.231. In addition, the protection device according to the invention is integral with the lock, which strengthens the overall resistance. The two parts of the protection device, in particular the front part, are tightened against the plaster of the lock, which prevents the passage of forcing tools.
De préférence, la pièce frontale est prolongée vers l'intérieur par un retour agencé pour passer sous le palâtre de la serrure et sur lequel est fixée une des vis de montage de la plaque arrière.Preferably, the front piece is extended inward by a return arranged to pass under the plaster of the lock and on which is fixed one of the mounting screws of the back plate.
L'invention sera bien comprise à la lecture de la description suivante faite en référence au dessin annexé dans lequel
la figure 1 est une vue schématique en perspective
éclatée d'une serrure selon un exemple de réalisation
de l'invention, sans le cylindre de sécurité; et
la figure 2 est une vue en coupe d'une partie du
dispositif de protection. The invention will be clearly understood on reading the following description made with reference to the accompanying drawing in which
Figure 1 is a schematic perspective view
exploded view of a lock according to an exemplary embodiment
of the invention, without the safety cylinder; and
Figure 2 is a sectional view of part of the
protection device.
boîtier 2 contenant le mécanisme de serrure commandant un pêne dormant 3 et un pêne demi-tour 4 qui traversent des fenêtres respectives de la têtière 5 de la serrure. Le pêne demi-tour 4 peut également être actionné par une poignée (non représentée) solidaire d'une tige carrée logée dans un alésage carré 6 d'une pièce pivotante. Le palâtre 2 comporte en outre une boutonnière traversante 7 pour le passage du cylindre de sécurité (non représenté).box 2 containing the lock mechanism controlling a deadbolt 3 and a half-turn bolt 4 which pass through respective windows of the headrest 5 of the lock. The latch bolt 4 can also be actuated by a handle (not shown) secured to a square rod housed in a square bore 6 of a pivoting part. The plaster 2 further comprises a through buttonhole 7 for the passage of the safety cylinder (not shown).
La serrure 1 est logée dans une fente 10 du chant 11 de la porte 12 et la têtière 5 est fixée par deux vis traversant des orifices 13 et vissées dans deux trous 14 de la porte 12. Le cylindre est ensuite monté dans la boutonnière 7 à travers une fenêtre oblongue 15 de la porte 12 et fixé, de manière traditionnelle, par une vis traversant un orifice 16 du chant 5 de la serrure 1.The lock 1 is housed in a slot 10 in the edge 11 of the door 12 and the headrest 5 is fixed by two screws passing through holes 13 and screwed into two holes 14 in the door 12. The cylinder is then mounted in the buttonhole 7 at through an oblong window 15 of the door 12 and fixed, in the traditional way, by a screw passing through an orifice 16 of the edge 5 of the lock 1.
La fenêtre 15 de la porte 12 a des dimensions adaptées au contour externe d'une pièce massive 20 faisant partie d'un dispositif de protection du cylindre. La pièce 20, qui est montée sur la face externe de la porte 12, est constituée d'un corps creux 21 muni sur sa face frontale d'un alésage 22 pour le passage de l'extrémité cylindrique du cylindre de sécurité.The window 15 of the door 12 has dimensions adapted to the external contour of a solid part 20 forming part of a cylinder protection device. The part 20, which is mounted on the external face of the door 12, consists of a hollow body 21 provided on its front face with a bore 22 for the passage of the cylindrical end of the security cylinder.
L'intérieur 23 (figure 2) du corps creux 21 est conformé en concordance avec le cylindre de sécurité. Le corps 21 est prolongé à son extrémité supérieure par une patte 24 traversée par un alésage taraudé 25 et comporte à son extrémité inférieure un retour 26 agencé pour passer sous le palâtre 2 de la serrure 1 et également percé d'un alésage taraudé 27.The interior 23 (FIG. 2) of the hollow body 21 is shaped in accordance with the safety cylinder. The body 21 is extended at its upper end by a lug 24 traversed by a tapped bore 25 and has at its lower end a return 26 arranged to pass under the plaster 2 of the lock 1 and also pierced with a tapped bore 27.
L'ensemble de la pièce 20 est enfoncé dans la fenêtre 15 jusqu'à ce que la face interne plane du corps 21 vienne en appui sur la face latérale adjacente du palâtre 2.The entire part 20 is pressed into the window 15 until the planar internal face of the body 21 comes to bear on the adjacent lateral face of the plaster 2.
Une plaque de fixation 30, munie d'une boutonnière 31 pour le passage du cylindre est ensuite appliquée, à travers la fenêtre 15 de la porte 12 sur la face interne de celle-ci, contre la face latérale opposée du palâtre 2 et en appui sur le retour 26 de la pièce 20. La plaque de fixation 30 est munie de deux alésages 32 et 33 pour le passage de deux vis 34 et 35. La vis 34 traverse un alésage 36 du palâtre 2 de la serrure 1 et se visse dans l'alésage taraudé 25 de la pièce 20. La seconde vis 35 vient se fixer dans l'alésage taraudé 27 du retour 26, de sorte que la serrure 1 est serrée entre la pièce 20 et la plaque de fixation 30, assurant une grande stabilité de l'ensemble et interdisant l'accès latéral au cylindre de sécurité. Toute action axiale sur le cylindre de sécurité tend à déformer le palâtre 2 ainsi que le foncet (non représenté) de la serrure 1, interdisant ainsi le retour du pêne dormant 3.A fixing plate 30, provided with a buttonhole 31 for the passage of the cylinder is then applied, through the window 15 of the door 12 on the internal face of the latter, against the opposite lateral face of the plaster 2 and in abutment on the return 26 of the part 20. The fixing plate 30 is provided with two bores 32 and 33 for the passage of two screws 34 and 35. The screw 34 passes through a bore 36 of the plaster 2 of the lock 1 and is screwed in the threaded bore 25 of the part 20. The second screw 35 is fixed in the threaded bore 27 of the return 26, so that the lock 1 is tightened between the part 20 and the fixing plate 30, ensuring great stability of the assembly and preventing lateral access to the safety cylinder. Any axial action on the safety cylinder tends to deform the plaster 2 as well as the lock (not shown) of the lock 1, thus preventing the return of the deadbolt 3.
Dans certains cas, en particulier pour des portes métalliques ou blindées, on peut prévoir que la plaque de fixation 30 est plus grande que la fenêtre 15 de manière à s'appuyer sur la périphérie métallique de cette fenêtre. On pourra dans ce cas boucher la fenêtre sur sa face intérieure par une pièce (non représentée), solidaire ou non de la plaque 30, percée d'alésages pour le passage des vis 34 et 35. La serrure 1 est ainsi serrée entre la pièce 20 et la pièce intermédiaire, cette dernière étant en appui sur la porte métallique de la porte par l'intermédiaire de la plaque de fixation 30. In certain cases, in particular for metal or armored doors, provision may be made for the fixing plate 30 to be larger than the window 15 so as to bear on the metal periphery of this window. In this case, the window can be plugged on its inner face by a part (not shown), whether or not integral with the plate 30, pierced with bores for the passage of the screws 34 and 35. The lock 1 is thus tightened between the part 20 and the intermediate piece, the latter being in abutment on the metal door of the door by means of the fixing plate 30.
