Definitions

  • the present invention relates to a double keyhole lock, particularly for the security of residential uses.
  • a reinforced door used typically as an entrance door of apartments and offices, is provided with suitable laminar reinforcement elements intended to provide overall stiffening and to make it difficult to produce damage for break-in purposes.
  • the hinges must be oversized in order to bear the great weight of the door and withstand any break-in blows and the lock must have bolts that protrude appropriately and are adapted to engage within respective selvages of the jamb that are particularly deep and firmly anchored to the wall.
  • Locks of this type normally provide for the actuation of the spring latch by means of a handle (in some cases provided only on the inner side of the door and in other cases on both sides) and of the bolts by means of the rotation of the key within the cylinder.
  • the aim of the present invention is to provide a double keyhole lock, particularly for the security of residential uses, whose behavior and operating modes are variable depending on the type of use set by users.
  • an object of the present invention is to provide a double keyhole lock, particularly for the security of residential uses, that is suitable for controlled enabling/disabling of the key reserved for service personnel and the like.
  • Another object of the present invention is to provide a double keyhole lock, particularly for the security of residential uses, that is adapted to increase the level of security with respect to traditional locks.
  • Another object of the present invention is to provide a selector for locks of reinforced doors and the like that has a low cost, is relatively simple to provide in practice, and is safe in application.
  • a double keyhole lock particularly for the security of residential uses, of the type that comprises a box-like containment body provided with suitable lateral openings, for the passage of at least one spring latch and of at least one bolt, with a plurality of substantially laminar members that are functionally associated with a first cylinder, operated by a respective key and accommodated in a first keyhole, with a rotatable element, for the engagement of a handle, which is associated with said at least one spring latch by means of lever systems and is designed for the movement of said spring latch, and with a latch that is functionally associated with a second cylinder, which is operated by a respective key and is accommodated in a second keyhole, and comprising a plate that performs a translational motion and is functionally associated in an upper region with said rotatable element and in a lower region with a laminar member that is jointly connected to the bolts by means of a carousel that is pivoted,
  • Figure 1 is a partially sectional perspective view of a first embodiment of a double keyhole lock, particularly for the security of residential uses, without some of its components;
  • Figure 2 is a partially sectional perspective view, taken along a different orientation with respect to Figure 1 , of the first embodiment of a double keyhole lock, particularly for the security of residential uses, without some of its components;
  • Figure 3 is a partially sectional perspective view of a second embodiment of a double keyhole lock, particularly for the security of residential uses, provided with some additional elements with respect to what is shown in Figures 1 and 2, and without other components;
  • Figure 4 is a partially sectional perspective view, with a different orientation with respect to Figure 3, of the second embodiment of a double keyhole lock, particularly for the security of residential uses, provided with some additional elements with respect to what is shown in Figures 1 and 2 and without other components;
  • Figure 5 is a partially sectional perspective view of a third embodiment of a double keyhole lock, particularly for the security of residential uses, provided with some additional elements with respect to what is shown in Figures 3 and 4 and without other components
  • Figure 6 is a partially sectional perspective view, with a different orientation with respect to Figure 5, of the third embodiment of a double keyhole lock, particularly for the security of residential uses, provided with some additional elements with respect to what is shown in Figures 3 and 4 and without other components
  • Figure 7 is a partially sectional perspective view of a fourth embodiment of a double keyhole lock, particularly for the security of residential uses, provided with some additional elements with respect to what is shown in Figures 5 and 6 and without other components;
  • Figure 8 is a partially sectional perspective view, with a different orientation with respect to Figure 7, of a fifth embodiment of a double keyhole lock, particularly for the security of residential uses, provided with some additional elements with respect to what is shown in Figures 5 and 6 and without other components.
  • the reference numeral 1 generally designates a lock with double keyhole 2, 3, particularly for the security of residential uses.
  • the lock 1 comprises a box-like containment body 4, which is provided with suitable lateral openings 5 for the passage of at least one spring latch 6 and at least one bolt 7, with a plurality of substantially laminar members 8 that are functionally associated with a first cylinder, which is operated by a respective key and is accommodated in the first keyhole 2, with a rotatable element 9, for the engagement of a handle, which is associated with the spring latch 6 by means of lever systems and is designed to move the spring latch 6.
  • the box-like body 4 comprises a latch 10, which faces outside through a corresponding seat 11 of the box-like body 4, that is functionally associated with a second cylinder, which is actuated by a respective key and is accommodated in the second keyhole 3.
  • the lock 1 further comprises a translating plate 12, which is functionally associated in an upper region with the rotatable element 9 and, in a lower region, with one of the laminar members 8 that is jointly connected to the bolts 7 by means of a carousel 13, which is pivoted in another point to the box-like body 4.
  • the box-like body 4 is substantially shaped like a parallelepiped, with two mutually opposite faces, a bottom 4a and the top, which have a large surface and four lateral edges: the upper one, the lower one, the front one, comprising the openings 5 and the seat 11 , and the rear one (not shown in the figure).
  • the box-like body 4 can be provided by adopting the standard dimensional specifications for this type of lock 1, with the advantage that it can be installed in any reinforced door without requiring any modification thereof.
  • the bolts 7 are four cylindrical elements, which are arranged in a parallel configuration and can slide transversely with respect to the lock 1.
  • the latch 10 When the latch 10 is in a preset positioning configuration set by the second cylinder, it produces a misalignment between an abutment member 14 of the rotatable element 9 on the translating plate 12 and the plate 12, with consequent mutual disengagement thereof.
  • a movable lamina 15 is interposed between the plate 12 and the abutment member 14 of the rotatable element 9; the lamina 15 is coupled to the plate 12 by means of a pivot 16 engaged in an appropriately provided slot 17 of the plate 12.
  • the lamina 15 can move from a first configuration, in which a protruding tooth 18 thereof is aligned and proximate to the abutment element 14, to a second configuration, in which the tooth 18 is separated and does not interfere with the stroke of the rotatable element 9: in this second configuration, the rotation of the element 9, by way of the action of the handle, does not impart a translational motion of the plate 12, with consequent rotation of the carousel 13 and retraction of the bolts 7. This means that in this second configuration a rotation of the handle is matched only by the retraction of the spring latch 6.
  • the movable lamina 15 is arranged so as to rest substantially on the bottom 4a of the box-like body 4 and has a longitudinal slot 19 which accommodates a pin 20 which is fixed to the bottom 4a. to guide the lamina 15 during its sliding.
  • the lock 1 comprises a substantially flat mask 21 , which is associated with the latch 10 by means of a protruding stem 22, which is engaged in a corresponding contoured slot 23.
  • the mask 21 can perform a translational motion from a raised arrangement, which corresponds to preset arrangements of the latch 10, to a lowered arrangement, which corresponds to the already mentioned preset positioning configuration of the latch 10, the one that corresponds to the disengagement of the rotatable element 9 from the bolts 7.
  • the mask 21 comprises an end flap 24, which is provided with a notch 25 that accommodates the fixed pin 20, and a protrusion 26, which rests against a contoured edge 15a of the movable lamina 15.
  • the preset positioning configuration of the latch 10, i.e., the one in which the rotation of the element 9 determines exclusively the retraction of the spring latch 6, corresponds to a complete extraction of the latch 10 with respect to the box-like body 4.
  • the abutment member 14 is constituted by an arm 27, which is coupled to the rotatable element 9 and is arranged substantially radially with respect to it.
  • the protruding tooth 18 is constituted by a flap of the lamina 15, which is folded substantially at right angles with respect to the lamina 15.
  • the operation of the lock 1 according to the invention is as follows.
  • the protruding stem 22 is arranged in a linear region of the contoured slot 23.
  • the stem 22 instead acts on a suitably contoured portion of the slot 23, causing a lowering of the mask 21.
  • the lowering of the mask 21 produces a lowering of the protrusion
  • the protrusion 26 which by sliding on the contoured edge 15a is forced with the edge 15a (in order to be able to descend, the protrusion 26 must move the contoured portion of the edge 15a).
  • the cylinders used may be substantially of any type; the adoption of specific locks for keys with a double blade instead of the cylinders is not excluded.

Abstract

Le verrou (1) doté d’un double trou de serrure (2, 3) selon la présente invention, est destiné en particulier à la sécurité des installations résidentielles et comprend un corps de confinement de type boîtier (4) pourvu d’ouvertures latérales appropriées (5), pour le passage d’au moins un loquet à ressort (6) et d’au moins un pêne (7), avec une pluralité d’éléments sensiblement laminaires (8) qui sont associés de façon fonctionnelle à un premier cylindre, actionné au moyen d’une clé respective et logé dans un premier trou de serrure (2), avec un élément rotatif (9), pour la mise en prise d’une poignée, qui est associée au ou aux loquets à ressort (6) au moyen de systèmes de levier et qui est conçue pour le mouvement du loquet à ressort (6), et avec un verrou (10) qui est associé de façon fonctionnelle à un second cylindre, actionné au moyen d’une clé respective et logé dans un second trou de serrure (3), et comprenant une plaque (12) qui effectue un mouvement de translation et qui est associée de façon fonctionnelle dans une région supérieure à l’élément rotatif (9) et dans une région inférieure à un élément laminaire (8), qui sont conjointement connectés aux pênes (7) au moyen d’un carrousel (13) qui pivote, à un autre point, vers le corps de type boîtier (4). L’agencement du verrou (10) suivant une configuration de positionnement prédéfinie, établie par le second cylindre, produit un décalage entre un élément de butée (14) de l’élément rotatif (9) sur la plaque de translation (12) et la plaque (12) elle-même, ce qui engendre un découplage mutuel de ces derniers ; la rotation de l’élément rotatif (9), faisant suite à la rotation de la poignée, entraîne la rétraction du ou des loquets à ressort (6) et du ou des pênes (7), à moins que le verrou (10) ne se trouve dans la configuration de positionnement prédéfinie, dans laquelle la rotation détermine uniquement la rétraction du ou des loquets à ressort (6).
