Definitions

  • the present invention relates to an improvement in the design of locks. More specifically, the present invention is concerned with improvements in the assembly and security of lock components.
  • the lock cylinder of a conventional pin-tumbler lock is cylindrical with a radially extending lobe along the length of the cylinder. Opposite side plates on the lock are provided with matching orifices such that the lock cylinder may be mounted in a passage therebetween.
  • the cylinder is usually secured to the body of the lock by a bolt which passes through the face plate of the lock and the lobe of the cylinder, transversely to the cylinder.
  • a lock comprising a body having first and second opposite side plates each having an orifice therein so as to form a passage therebetween, a cylindrical lock cylinder passing through said passage and driveably connected with a rotatable cam, a bolt member mounted for movement relative to the body and moveable by said cam, characterised by said lock cylinder received by first and second close-fitting sleeves which are secured thereto, said second sleeve being removably secured, such that an inner end of each of said first and second sleeves abuts the first and second side plates respectively so as to prevent axial movement of the lock cylinder, the first sleeve has at least one projection on its inner end which is received in the orifice of the first side plate and is a close fit therein so as to substantially prevent rotation of the first sleeve, and wherein the first side plate has an upstanding ridge on an inner face, said ridge located such that when the lock is in the locked position it is adjacent the cam and sufficiently limits axial movement of the lock
  • such a lock is easily assembled.
  • a free end of the lock cylinder having the first sleeve and cam attached thereto is passed through the first side plate until the cam is inside the body and the at least one projection on the first sleeve is located in the orifice in the first side plate.
  • the second sleeve is then mounted on the free end of the lock cylinder. Disassembly is merely the reverse process. However, when the lock is in its locked position, axial and rotational movement of the lock cylinder is prevented.
  • the cam abuts the ridge on the first side plate such that no axial movement of the lock cylinder is possible.
  • a corresponding ridge is provided on an inner face of the second side plate, in alignment with the ridge on the inner face of the first side plate.
  • the second sleeve is in screw-threaded engagement with the lock cylinder.
  • the first sleeve is provided with at least two projections on its inner end.
  • the lock is provided with deadlocking means. More preferably, said deadlocking means is effective when the lock is in a locked and unlocked position.
  • the lock may be provided with means to increase the throw of the bolt.
  • a lock cylinder 2 is of the pin tumbler type more fully described in copending British Application No. 9715114.6.
  • the lock cylinder 2 comprises a stator 4 and a rotor 6, the latter being mechanically coupled to a cam 8 and having an axially extending keyway 10 therein.
  • a first end 2a of the locking cylinder 2 is received by and is a close sliding fit with a first tubular sleeve 12.
  • the first sleeve 12 is provided with a pair of diametrically opposed projections 12b (only one shown).
  • a first side plate 14 (shown in part) forming part of a lock body has an elongate orifice 16 therein, which is capable of receiving a second end 2b of the locking cylinder 2 which is part screw-threaded, the cam 8 and the projections 12b on the first sleeve 12.
  • a region 16a of the orifice 16 has a part circular boundary which corresponds to the circumference of the locking cylinder 2, such that when in place, lateral movement of the locking cylinder 2 is prevented.
  • Regions 16b of the orifice 16 corresponding in shape to the projections 12b on the first sleeve 12 prevent rotation of the locking cylinder 2 when in place.
  • the second end 2b of the lock cylinder 2 is inserted through the orifice 16 in the first side plate 14 until the cam 8 has passed through the orifice 16 and the second end 2b protrudes through a corresponding orifice 20 (Fig 2) in a second side plate 22 (Fig 2).
  • the lock cylinder 2 is then rotated until the cam 8 is correctly positioned (the cam 8 is directly or indirectly engageable with a bolt member, not shown) and the projections 12b on the first sleeve 12 are located in the orifice 16 in the first side plate 14.
  • a second sleeve 24 (Fig 2) is mounted on the second end 2b of the lock cylinder 2 and engaged with the screw thread until it abuts the second side plate 22.
  • the lock is in a locked position and the cam 8 abuts the upstanding ridge 18 on the inner face 14a of the first side plate 14 (shown in part) and a corresponding upstanding ridge 18b on an inner face 22a of the second side plate 22(shown in part). It will be apparent that even if the second sleeve 24 is accessible and removed, the lock cylinder 2 is firmly anchored in place.
  • a lock which is highly resistant to unauthorised removal of the lock cylinder 2 when the lock is in its locked position, yet which allows easy assembly and disassembly when required, for example for maintenance or replacement of the lock cylinder 2.

Claims (8)

  1. Serrure comprenant un corps comportant une première (14) et une deuxième (22) plaques latérales opposées comportant chacune en son sein un orifice (16, 20) de façon à former un passage entre elles, un barillet de serrure cylindrique (2) traversant ledit passage et raccordé par entraínement à une came mobile en rotation (8), un élément formant pêne monté de façon à se déplacer par rapport au corps et mobile par ladite came (8), caractérisée en ce que ledit barillet de serrure (2) est reçu par des première (12) et deuxième (24) douilles à ajustement serré qui sont fixées à celui-ci, ladite deuxième douille (24) étant fixée de façon amovible, de sorte qu'une extrémité intérieure de chacune desdites première (12) et deuxième (24) douilles bute respectivement contre les première (14) et deuxième (22) plaques latérales de façon à empêcher tout déplacement axial du barillet de serrure (2), la première douille (12) comporte au moins une saillie (12b) sur son extrémité intérieure (12a) qui est reçue dans l'orifice (16) de la première plaque latérale (14) et qui y est ajustée de façon serrée de façon à empêcher pratiquement toute rotation de la première douille (12), et dans laquelle la première plaque latérale (14) comporte une bosse verticale (18a) sur une face intérieure (14a), ladite bosse (18a) étant positionnée de sorte que lorsque la serrure est dans la position verrouillée, elle se trouve adjacente à la came (8) et limite suffisamment le déplacement axial du barillet de serrure (2) de sorte que l'au moins une saillie (12b) sur la première douille (12) ne peut pas être complètement retirée de l'orifice (16) dans la première plaque latérale (14), même lorsque la deuxième douille (24) est retirée, tandis que lorsque la serrure est dans une position ouverte, ce déplacement axial n'est pas limité par ladite bosse (18a).
