Definitions

  • the present invention relates to a break-in resistant lock particularly of the type which can be operated by means of twin-blade keys.
  • Locks associated with twin-blade keys are constituted by a main box- like body provided with a seat (which is arranged substantially transversely) suitable for the insertion of the key.
  • the key once inserted, is arranged so that its coded portion is aligned with a plurality of coding plates (normally termed tumblers) which can perform a partial translational motion along preset directions.
  • a plurality of coding plates normally termed tumblers
  • the rotation of the key in the seat entails a movement of the plates (tumblers), which is matched by the disengagement of a rod (which is normally engaged by interference on the plates); such rod can thus be made to perform a translational motion by the rotary motion of the key in the seat.
  • the bolts are stably coupled on the front portion of the rod: the translational motion of the rod entails the protrusion of the bolts from the front edge of the lock, with consequent stable engagement of the bolts in the receptacles of the jamb, ensuring the correct closure of the door in which the lock is installed.
  • This type of lock ensures a good level of protection against break-in actions of the destructive type, since the generous dimensions allow embodiments of the armored type.
  • an object of the present invention is to provide a break-in resistant lock for double-blade keys of the type which can be recoded, provided with means adapted to contrast any break-in action which falls within the field of lock picking.
  • Another object of the present invention is to provide a break-in resistant lock which has a low cost, is relatively easy to provide in practice, and is safe in application.
  • This aim and these objects, as well as others which will become better apparent hereinafter, are achieved by the present break-in resistant lock, of the type which comprises a box-like body for accommodating a plurality of contoured plates provided with a respective portion which is suitable for detachable engagement on a corresponding area of a rod which can perform a translational motion and supports, at its free end, at least one bolt which can retract monolithically with said rod, said plates being able to perform a vertical translational motion by way of the action of said key and releasing, when they are raised, the translational motion of said rod and said bolts for their retraction and protrusion, characterized in that at least one of said plates comprises at least one area provided with at least one seat which is aligned and proximate to at least one protrusion which is shaped substantially complementarily with respect to the shape of said seat, said at

  • Figure 2 is an enlarged-scale view of a detail of the perspective view of Figure 1;
  • Figure 3 is a partially sectional perspective view of a lock according to the invention in the break-in resistant locking configuration
  • Figure 4 is an enlarged-scale view of a detail of the perspective view of Figure 3. Ways of carrying out the invention
  • the reference numeral 1 generally designates a break-in resistant lock.
  • the lock 1 comprises a box-like body 2 for accommodating a plurality of contoured plates 3 provided with a respective portion (not shown in the figure) which is suitable for detachable engagement on a corresponding area of a rod 4, which can perform a translational motion and supports, at its free end 5, at least one bolt 6 which can retract monolithically with the rod 4.
  • the rod 4 supports (with its end 5) four mutually parallel bolts 6.
  • the plates 3 can perform a vertical translational motion by way of the action of the key (not visible in the figure) and are designed, when they are raised, to release the translational motion of the rod 4 and accordingly of the bolts 6 for their retraction and protrusion.
  • At least one of the plates 3 comprises at least one area 7 provided with at least one seat 8 which is aligned and proximate to at least one protrusion 9 which is shaped substantially complementarily with respect to the shape of the seat 8.
  • the at least one plate 3 provided with the at least one seat 8 can oscillate about a guiding pivot 10 rigidly coupled to the box-like body 2.
  • the oscillating motion is possible between two extreme positions defined by the geometry of the structure of the lock 1.
  • This movement is in fact possible from a first configuration for the mutual engagement of the at least one seat 8 with the respective at least one protrusion 9, as a consequence of external break-in actions intended to produce the forced retraction of the rod 4 and the retraction of the bolts 6 (a situation shown in Figure 4), to a second inactive configuration, in which the seat 8 and the protrusion 9 are spaced and the translational motion of the plates 3 is free and therefore the rod 4 can be extracted and retracted (situation shown in Figure 2).
  • the burglar in fact keeps the rod 4 forced so as to force its retraction and by means of a second tool lifts one by one the superimposed plates 3 until the rod 4 is released completely and is thus free to perform a backward translational motion, causing the retraction of the bolts 6.
  • the locking of the at least one plate 3 produced by the stable engagement of the seat 8 of the portion 7 with the fixed protrusion 9 (which occurs indeed in case of forcing actions from the outside which correspond to tractions of the rod 4 in the direction for its retraction) makes it impossible for the plates 3 to perform a translational motion by way of the action of the second break-in tool.
  • the plates 3 comprise at least one respective guiding slot H 5 which accommodates a pivot 10 which is rigidly coupled to the box-like body 2: in practice, the pivot 10 constitutes the center of rotation of each plate 3 upon every break-in action matched by an attempt at forced retraction of the rod 4 and of the bolts 6.
  • the slot 12 is wider than the pivot 13 that it accommodates.
  • the slot 11 instead has shapes and dimensions which are complementary to those of the respective pivot 10.
  • a retraction of the rod 4 (caused for example by a break-in attempt by lock. picking) is matched by a rotation of the plate 3 (or plates 3) about the pivot 10 snugly accommodated in the slot 11 and a consequent movement of the wider slot 12 until interference with the respective pivot 13 occurs.
  • the lock 1 comprises elastic means 14 which are interposed between a fixed abutment and a region 15 which is proximate to the seat 8 for the elastic forcing of the at least one plate 3 in the second configuration for mutual separation and lack of interference between the seat 8 and the protrusion 9 and for stably maintaining said configuration unless external mechanical interference occurs.
  • the elastic means 14 are constituted by an axially acting spring, which is accommodated within an element 16 which is rigidly coupled to the box-like body 2.
  • the free end of the spring rests on the region 15 which lies proximate to the seat 8 of the at least one plate 3.
  • the seats 8 are a plurality and are mutually successive so as to constitute a sort of set of teeth.
  • the element 16 rigidly coupled to the box-like body 2 and designed to accommodate the axially acting spring (the elastic means 14) also comprises the protrusion 9: this is merely a wedge-shaped protrusion which extends from its lower end toward the portion 7 of the plate 3 which faces it.
  • each plate 3 is constituted by a main lamina, which is provided with the at least one seat 8 for accommodating the protrusion 9, and by a strip.
  • the main lamina and the strip face each other and are provided with teeth for mutual meshing according to a plurality of configurations in order to allow recoding of the lock 1.
  • This constructive choice allows to obtain even locks for twin-blade keys of the type which can be recoded and provided with means for hindering lock picking actions.

Abstract

Cette invention concerne une serrure anti-effraction (1), du type qui comprend un corps en forme de boîte (2) conçu pour loger une pluralité de plaques profilées (3) munies d'une partie respective adaptée pour venir en prise de manière libérable avec une surface correspondante d'une tige (4). Ladite tige peut effectuer un mouvement de translation et elle supporte, à son extrémité libre (5), au moins un pêne (6) apte à se rétracter d'un seul tenant avec la tige (4). Les plaques (3) peuvent effectuer un mouvement de translation vertical par l'intermédiaire de l'action de la clé et, quand elles sont relevées, elles libèrent le mouvement de translation de la tige (4) et des pênes (6) en vue de leur rétraction et de leur déploiement. Au moins une des plaques (3) comprend au moins une zone (7) munie d'au moins un siège (8) qui est aligné à la ou aux saillies (9) dont la forme est sensiblement complémentaire à celle du siège (8). La ou les plaques (3) munies du ou des sièges (8) sont aptes à osciller autour d'un pivot de guidage (10) rigidement couplé au corps en forme de boîte (2), entre une première configuration d'engagement mutuel du ou des sièges (8) et de la ou des saillies respectives (9), dans laquelle le mouvement de translation des plaques (3) n'est pas permis et donc la tige (4) est bloquée, suite à des actions externes d'effraction visant à retirer la tige (4) et les pênes (6), à une seconde configuration inactive, dans laquelle le siège (8) et la saillie (9) sont espacés et le mouvement de translation des plaques (3) est permis et donc la tige (4) peut être extraite et rétractée.
