Definitions

  • the present invention relates to a cylinder and barrel lock for office writing desk and file cabinet drawer assemblies, which is so designed that the lock cylinder turning in the lock barrel can be easily replaced.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a lock for office writing desk and file cabinet drawer assemblies which can be replaced in a very quick and simple way.
  • a main object of the present invention is to provide such a lock which can be replaced directly by the user.
  • Yet another object of the present invention is to provide such a lock which, in addition to being easily replaceable, can also be fitted to new drawer assemblies.
  • a cylinder and barrel lock for office writing desk and file cabinet drawer assemblies comprising a lock cylinder which can turn inside a lock barrel as driven by a turning key tool, characterized in that said cylinder is removably restrained in said barrel by means of a restraining resilient element engaging said barrel and disengageable from the latter by engaging in the lock keyhole a further key tool having a set length.
  • the cylinder and barrel lock for office writing desk and file cabinet drawer assemblies comprises, likewise to a conventional type of cylinder lock, a lock cylinder 1 and a lock barrel 2, bearing a number of blade elements 3, which are biassed by respective springs.
  • the lock cylinder arranged in the lock barrel, at the end of which there is provided a suitable mechanical member for locking all of the drawers of a drawer assembly, can be turned by engaging in the lock keyhole 4 a specifically designed key.
  • the lock barrel is provided, at the rear end portion thereof, with an inner circumferential ridge 5 thereon can rotatably engage a resilient shaped element 6.
  • this resilient element is provided with a reversed-U central portion, from the bottom of which extend two symmetrical upwardly bent portions 6′.
  • the lock cylinder 1 is provided with a corresponding slot which can slidably receive the above mentioned resilient element, side ridges 8 being moreover provided for restraining said resilient element by engaging the inwardly bent end portions thereof.
  • the resilient element in operation, will normally caused to be downwardly displaced by the urging action provided by the above mentioned side ridges 8 so as to allow the lock to be conventionally actuated by means if a suitably contoured lock key.
  • the subject lock also provides for the use of a further lock key 9, having any suitable contour which, as engaged in the keyhole 4 will engage, with one end 10 thereof, an intermediate portion of the resilient element 6 so as to push the latter upwardly.
