Definitions

  • the present invention relates to a safety lock with a high security of use, to be mounted in general for doors, gates, safes, etc., more specifically a safety lock which comprises a tumbler plate lock and an additional lock having a blockage pin which ensure the safety of the safety lock against any action which falls within the field of lock picking.
  • the present invention relates to a safety lock of the type referred to as "plate lock”, “lever lock”, “double-sided lock” and “tumbler locks” which are widely practiced in the art and each safety lock of the above mentioned type can be opened/closed by a specific key preferably provided with double ore one sided tailpieces.
  • Said safety locks have at least one deadbolt inside a case associated to a plurality of plates, also called gorges or tumblers, and a spring-latch with a key used to move said tumblers from a forward closed position to a retracted open position.
  • the safety lock mechanism that opens and closes locks feature differentiated passage notches which, when aligned, create the profile of the operating key.
  • the interaction of one of the bits of the key with the edge of the recesses causes, the movement of the plurality of tumblers.
  • An unauthorized person may use picklocks for tensioning' the bolt member in the opening direction, slowly and selectively lift each individual safety plate in an attempt to detect the corresponding enabling position.
  • An unauthorized person may try to lift each individual safety tumbler to detect the corresponding enabling position. So it is considered that the key hole of the abovementioned type of the locks can be manipulated by an unauthorized person by a lock pick or similar tools to retract the bolt also by imposing excessive amount of power.
  • the bolt member may be tensioned in the opening direction by a pusher and the manipulation instrument is subsequently inserted, tumblers being pushed upwards by rotation of the instrument itself.
  • the picklock simulates the presence of the key in the lock
  • a prior art publication in the technical field of the present invention may be referred to as DE19906271 among others, the document disclosing a lock having lock bolt/deadbolt which moves the security mechanism.
  • Said lock comprises an integrated inbuilt safety mechanism or a second cylinder lock which has a nose to prevent key hole closing at least partially when it is in in a locked state.
  • EP903455 and WO2009/057170 describe locks provided with security devices which are designed to prevent attempted break-ins performed using the "sensing" technique.
  • the present invention provides an arrangement in a relation to the tumbler plate lock with a conventional cylinder which is defined by the characterizing features as defined in Claim 1.
  • Primary object of the present invention is to overcome the problem described, providing the lock with an additional lock having blockage pin for blocking the tumblers and also sliding bars, which prevent the retraction thereof by violent and/or tampering means.
  • Another object of the present invention is to provide a safety lock with an additional security improvement and enabling two side usage when is needed, without any significant changes.
  • the present invention relates to a safety lock which comprises a case; a bolt member mounted movable in the case and displaceable, when in use, by means of rotation of a key in the lock between a first position and a second position corresponding, respectively, to the open condition and to the closed condition of the lock.
  • Said safety lock further comprises an upper sliding bar, lower sliding bar, an additional deadbolt within the case having an additional lock member and additional deadbolt movably mounted in the case and, when in use, translatable by rotation of a second key in the additional lock between a first position and a second position corresponding, respectively, to the open condition and to the closed condition of the additional lock.
  • Said additional lock member comprises at least one blockage pin which is shaped and dimensioned to engage with corresponding protrusion provided at least one of sliding bars, when the additional lock is in the closed condition, which block the movement of the deadbolt and sliding bars.

  • the operation of the additional lock (21) shown in figures correspond to generally one turn and the operation of the tumblers-plate lock correspond to generally more than one turn must be repeated for the number of turns necessary to cause complete opening/closing of the lock, which depend on the length of the toothed window (15) of the tumblers (11).
  • the tumbler-plate lock mechanism of the safety lock (17), shown in fig. 4 is in a opened/first position, turning of the key (27) triggers the plurality of tumblers (11) to project outside of the case (2).
  • a safety lock pin (34) is guided in slots which are provided at upper sliding bar (18a), lower sliding bar (18b) and bolt member (19) passes through them.
  • the main objective of the invention is aimed at effectively block the tumblers in the locked condition with an arrangement of the blockage pin (22). It constitutes an effective and reliable solution that eliminates the displacement of the tumblers (11) and the sliding bars (18a, 18b) for using blockage pin (22) with an additional lock (21).
  • the invention ensures that security of the safety lock (17) is enhanced not only with an additional lock (21) but also a blockage pin (22) of the additional lock (21) which maintains the blockage of the system.
  • the unauthorized person may keep the bolt member (19) forced so as to force its retraction and by means of a second tool lift one by one the superimposed tumblers 11 until the bolt member (19) is released completely.
  • This kind of attacks may cause the retraction of the deadbolts (12).
  • Blocking of the sliding bars (18a, 18b) as well as the bolt member (19) produced by the stable engagement of the blockage pin (22) of the actuator (23) with the protrusion (28) makes it impossible for the deadbolt retracted motion by way of the action of the break-in tool.
  • the actuator (23) of the additional lock (21), as shown in figure3 carries the bolt and has the member slot (32).
  • the lower edge of the actuator (23) has at least one teeth (36) on which acts the pawl of the cylinder lock in order to displace it, by means of one or two turns, in the throwing or withdrawal (-X, +X) direction.
  • Number of the teeth (36) of the lower edge of the actuator (23) can be greater than that shown in the drawings, in which case their total displacement would require more than one turns of the cylinder lock.
