Definitions

  • the present invention relates to an improved lock mechanism having a cylinder specially designed to break along a pre-determined line whereby the remaining cylinder can still prevent unauthorized access.
  • the present invention is aimed at preventing unauthorized access to lock holders' premises in the manner to break lock cylinders.
  • Lock breaking is generally accomplished by use of a hand tool suitable for engaging with the outer face of the cylinder and in the form to grasp said outer contour of the cylinder in order for applying pressure on the cylinder by twisting the same.
  • These instruments specially adapted for the specific purpose of breaking the cylinder effect breaking along the most vulnerable part of the cylinder; that is around the bridge part in between two cylinder halves wherein the cylinder is mounted to the door by a mounting screw.
  • the present invention overcomes the above-mentioned shortcomings by way of providing a special breaking line along the cylinder, said line being mechanically weakened to be ruptured in response to a breaking force applied by a suitable hand tool.
  • the lock cylinder according to the present invention is therefore not fully detached from the door with the exception of the outer cylinder part which can be removed upon rupture along the pre-determined mechanically weakened line, the remaining cylinder still being operational.
  • the remaining cylinder part can hence still be operated by an authorized user having the correct key.
  • the present invention therefore provides a lock cylinder which is still operational in terms of preventing unauthorized access after a part of the cylinder is detached.
  • One of the prominent objects of the present invention is to provide a lock cylinder having a special breaking line along which breaking occurs in response to twisting forces applied on the outer contour of the cylinder by a special tool.
  • Another object of the present invention is to provide a lock cylinder which is still operational in terms of preventing unauthorized access after a pre-determined part of the cylinder is detached.
  • the present invention proposes a lock cylinder conventionally having two cylinder halves with respective cylinder cores and housings accommodating core pins and housing pins for sensing a key inserted into the key slot within said cylinder core.
  • the lock cylinder core's pins being conventionally aligned to allow rotation of the plug to effect locking and unlocking by a correct key, said core pins are spring tensioned by respective housing pins.
  • the outer half-cylinder according to the present invention is arranged in the form of an outer part and a longitudinally longer inner part the connection between those parts being mechanically weakened and therefore firstly breakable in response to twisting forces applied on the periphery of the outermost surface of said outer part.
  • pin tumbler key lock cylinders generally comprise a cylinder core provided with a plurality of longitudinally spaced pinholes extending radially of the key slot being in communication with the cylinder housing.
  • the pinholes line up with a similar set of pinholes in the cylinder housing.
  • a shear line exists between the rotating cylinder and the cylinder housing.
  • Cylinder core pinhole and housing pinhole receive pins referred to lower and upper pins.
  • the cylinder assembly (11) of the invention conventionally comprises two cylinder halves (11a, 11b) connected to each other by a bridge region where a mounting screw is mounted through a screw hole (12).
  • a key slot (13) extends along the cylinder core (15) and when a proper key is introduced thereto, pins in the core (15) and in the cylinder housing (14) respectively in each consecutive pinhole (18) are so aligned along the shear line (17) that rotation of the key is possible.
  • the outer cylinder half (11b) that is the cylinder half (11b) facing outside the door in which the cylinder is installed, is arranged in the form of two parts divided by a mechanically weakened line positioned on a transversal cross-section of said outer cylinder half (11b).
  • Mechanical weakening is carried out in the manner to form partly emptied vertical planes in between two consecutive pinholes (18 and 19) and core (15) portions as shown in Fig. 2 .
  • Fig. 3 demonstrates the cross-section of the mechanically weakened region in Fig. 2 .
  • mechanical weakening is effected in the manner to provide emptied spaces around two central connection parts 20 and 21, which are respectively located along the cylinder housing (14) and core (15). Emptying can be carried out by a suitable cutting tool to obtain a semi-cut region. All regions outside the hatched regions 20 and 21 in Fig. 3 are emptied to provide a pre-determined line that is breakable at first in response to twisting forces applied on the periphery of the outermost surface of said outer cylinder half (11b).
  • a key introduced to the key slot (13), on the other hand, can be advanced in its entirety as the key slot (13) is not interrupted by the upper connection part (21).
  • the upper connection part (21) is actually located within the rotatable plug and is therefore rotatable as the key is rotated.
  • said upper connection part (21) and the lower connection part (20) are broken in sequence and the outer part of the outer cylinder half (11b) becomes freely removable. Said outer part being taken out, the cipher pins within the remaining inner part of said outer cylinder half (11b) are still intact and operational so that the proper key holder can open the door even the cylinder (11) is now broken and partly taken out.
  • the present invention proposes a lock cylinder (11) comprising a housing (14) and a core (15) in the form of two cylinder halves (11a, 11b) divided by a bridge region having a screw hole (12) for mounting said lock cylinder (11) to a door.
  • One of said cylinder halves (11b) is arranged in the form of two parts divided by a mechanically weakened line positioned on a vertical cross-section of said outer cylinder half (11b) and said mechanically weakened line being provided in the form of emptied spaces around two central connection parts 20 and 21, respectively located along the cylinder housing (14) and core (15).
