Definitions

  • the present invention relates to a break-in resistant double-bit lock and a related key.
  • Bulgarian lockpick is a decoder for double-bit locks.
  • the aim of the present invention is to solve the above mentioned drawbacks, by providing a break-in resistant double-bit lock and a related key which prevent break-ins using specific decoders for double-bit locks, of the type normally known as Bulgarian lockpicks and the like.
  • an object of the invention is to provide a break-in resistant double-bit lock and a related key, which are complex to pick with any type of utensil.
  • Another object of the present invention is to provide a break-in resistant double-bit lock and related key which is low cost, easily and practically implemented and safely applied.
  • a break-in resistant double-bit and a related key characterized in that the access opening to the accommodation cavity of said key is contoured so as to define a central portion from which branch two mutually opposite slots, at least one of said slots comprising a portion, with a curved progression, with the lower edge arranged at a height that is substantially not lower than the midpoint plane of the respective slot, the head of said key comprising a central body from which branch two mutually opposite tongues, of which at least one is provided with at least one respective codifiable edge, at least one of said tongues comprising a region, with a curved progression, with the lower edge arranged at a height that is substantially not lower than the midpoint plane of the respective tongue of said head of said key.

  • Figure 9 is a sectional front elevation view, taken along a transverse line, of a further embodiment of a key according to the invention.
  • the reference numeral 1 generally designates a break-in resistant double-bit lock and the reference numeral 2 a related key.
  • the access opening 3 to the accommodation cavity of the key 2, in the lock according to the invention, is contoured so as to define a central portion 4 from which branch two mutually opposite slots 5 and 6.
  • At least one of the slots 5 and 6 comprises a portion, respectively 7 and 8, with a curved progression.
  • the portion 7, 8 will have a partial protrusion with respect to the plane containing the remaining part of the access opening 3 (as well as the remaining part of the slots 5 and 6). More specifically the portion 7, 8 will have the lower edge arranged at a height that is substantially not lower than the midpoint plane of the respective slot 5, 6, thus presenting an obstacle to the insertion in the access opening 3 of any flat component.
  • Each curved portion 7 and 8 will thus define a deviation from the plane containing the central portion 4 and the ends of the slots 5 and 6: it is thus evident that the access opening 3 will not lie on a single plane but will comprise deviations with respect to it (which are constituted by the portions 7 and 8). It can thus be seen that it is not possible to accommodate a double- bit key of the conventional type in the opening 3 according to the invention if the coded head has elements that are mutually coplanar: there would in fact be interference between the head of the key and the portions 7 and 8 of the opening 3 if one attempted to insert a traditional key.
  • the head 9 of the key 2 comprises a central body 10 from which branch two mutually opposite tongues 11 and 12.
  • At least one of the tongues 11 and 12 is provided with at least one respective codifiable edge, respectively 13 and 14.
  • Each tongue 11 and 12 can moreover be provided with a region, respectively 15 and 16, with a curved progression.
  • the region 15, 16 has a partial protrusion with respect to the plane containing the remaining part of the head 9 of the key 2. More specifically, each region 15, 16 will have the lower edge arranged at a height that is substantially not lower than the midpoint plane of the respective tongue 11 , 12 of the head 9 of the key 2, in order to present a shape complementary to that of the access opening 3 described previously.
  • the portion 7 with curved progression has a shape structure that is substantially of the type of an arc of circumference (or in any case a curve that is comparable thereto, even if it is at least partially irregular) which constitutes the connection between a first part 7a associated with the central portion 4 and a second part 7b associated with the respective slot 5.
  • the region 15 with curved progression of the head 9 of the key 2 has a shape structure that is substantially of the type of an arc of circumference which constitutes the connection between a first portion 15a associated with the central body 10 and a second portion 15b associated with the respective tongue 11.
  • the portion 8 with curved progression will have a shape structure that is substantially of the type of a corner angle formed by a first slit 8a associated with the central portion 4 and a second slit 8b associated with the respective slot 6.
  • the region 16 with curved progression of the head 9 of the key 2 has a shape structure that is substantially of the type of a corner angle which constitutes the connection between a first strip 16a associated with the central body 10 and a second strip 16b associated with the respective tongue 12.
  • protrusions with respect to the plane containing the central portion 4 and the ends of the slots 5 and 6, as well as the central body 10 and the ends of the tongues 1 1 and 12, can also be facing in mutually opposite directions.
  • central portion 4 can have a cross-section that is preferably selected from among circular, polygonal and combinations thereof.
  • the central body 10 can also have a cross-section that is preferably selected from among circular, polygonal and combinations thereof.
  • both of the slots 5 and 6 can comprise a portion 7 and 8, with a curved pattern, with the lower edge arranged at a height that is substantially not lower than the midpoint plane of the respective slot 5, 6: this will make it possible to increase security, by preventing the (forced) insertion of a key of the conventional type and/or of a utensil having such shape.
  • both of the tongues 1 1 and 12 comprise a respective region 15 and 16, with curved progression, with the lower edge arranged at a height that is substantially not lower than the midpoint plane of the respective tongue 11 , 12 of the head 9 of the key 2: this is in order to be able to be correctly inserted into the access opening 3 described previously.
  • the access opening 3 and the head 4 of the key 2 have a shape that is at least partially contoured substantially like a letter "M".
  • portion 7, 8 with curved progression profitably will have at least one protruding tooth 17 or 18 which constitutes an obstacle upon the insertion of components of the type of keys 2 with substantially flat tongues 11 , 12 and tools with substantially flat lateral appendages.
  • the break-in resistant double-bit lock 1 and the related key 2 prevent break-ins perpetrated using specific decoders for double-bit locks, of the type normally called Bulgarian lockpicks and the like.
  • the break-in resistant double-bit lock 1 is also particularly effective against other types of break-in with any type of utensil, which is due to the fact that the contoured opening 3 does not permit the insertion of utensils having flat portions (which are very efficient for actuating the internal lever mechanisms adapted to the movement of sliding latches).
  • the break-in resistant double-bit lock 1 and the related key 2 are low cost and are easily and practically implemented, and are safely applied.
  • the regions 15 and 16 of the key 2 can be obtained by subjecting a traditional key to the action of a press provided with correctly shaped molds and/or by way of mechanical processing to remove material from a block of greater dimensions than those of a traditional key.
  • the contoured opening 3 can be provided by punching or die cutting with a specific automatic machine.
  • the materials employed, as well as the dimensions, may be any according to requirements and to the state of the art.
