Definitions

  • This invention relates to a combination lock, for example for use as a front door lock, or for any other purpose wherein a rotary unlocking and locking motion is desired.
  • the invention provides a combination lock comprising a rotatable and axially movable plunger, a plurality of axially displaceable pins around the plunger, a rotary ward disc carried by the plunger and cooperating wit.- said pins to allow rotary movement of the plunger only when selected ones of the pins are axially displaced relative to tne remainder, and a member carried by the plunger and capable of moving the pins to an aligned position upon axial movement of the plunger.
  • the lock comprises a cylindrical barrel closed at one end by a front plate, centrally of which a spigot surrounds the outer end of a plunger terminating in a handle and around the spigot a number of equally spaced bore holes allow the heads of the same number of pins to project therefrom.
  • a ward disc may be carried by the plunger inside the housing and selected ones of the pins may have slots which are aligned with the ward disc when they are displaced.
  • Eah pin may also have a slot in its outer side in the corresponding position.
  • each pin has a central enlarged portion in which both said slots are formed.
  • An outer setting plate carried by the plunger may engage the outer shoulders and an inner resetting plate may engage the inner shoulders.
  • each pin remote from its head can be prevented from rotation by engagement with a resetting member, this member preferably being movable to allow each pin to be rotated through 180° so as to enable it to be chosen to be one of said selected ones or not as desired,
  • a resetting member this member preferably being movable to allow each pin to be rotated through 180° so as to enable it to be chosen to be one of said selected ones or not as desired,
  • a first preferred embodiment of lock 10 of the invention comprises a cylindrical barrel 11 closed at one end by a front late 12. Centrally of the front plate 12 a spigot 13 surrounds the outer end of a plunger 14 terminating in a handle 15 and around the spigot 13 ten or any other number of equally spaced bores 16 allow the heads of the same number of pins 17 to project therefrom.
  • the pins 17 are axially slidable.
  • a ward disc 18 is carried by the plunger 14 iinside the housing and selected ones of the pins 17, for example the upper pin 17a in Fig. 1, have slots 19 which are aligned with the ward disc 18 when they are displaced inwardly towards the inner end of the barrel 11. The . remainder have slots 20 which are aligned with the ward disc 18 when they are not so displaced.
  • Each of the pins 17 also has a slot 21 in its outer side in the corresponding position.
  • Each pin 17 has a central enlarged portion 22 in which both said slots 19/20 and 21 are formed and inner and outer shoulders 29, 30 are at each end of the central enlarged portion 22.
  • An outer scrambling plate 23 carried by the plunger 14 can engage the outer shoulders 30 and an inner scrambling plate 24 can engage the inner shoulders 29.
  • the pins 17 will normally all lie in their inner positions with their outer ends close to the surface of the front plate 12. To open the lock 10 under these circumstances the user pulls the plunger 14 outwardly to cause the inner setting plate 24 to push all the pins 17 to protrude from the front plate 12. He then pushes said selected pins 17a (known only to himself) inwards, enabling the ward disc 18 to rotate and thus the plunder 14.
  • a non-circular protrusion 25 on the inner end of the plunger can operate a sliding bolt or the like.
  • Each pin 17 is rotatably mounted by the barrel assembly 11 and its inner end has a non-circular portion 26 slidable relative to a slot 27 in a slotted circular resetting member in the form of a plate 28.
  • a plate 28 By pressing this plate 28, to the left in Fig. 1 against the action of a spring 30, the user is enabled to rotate the pins 17 to bring one or other of said slots 27 into its radially inner operative position.
  • the plate 28 can now be returned to the normal locking position,
  • the lock can be made to act as a deadlock or a conventional spring lock by selecting the rotational position of the plunger 14 at which the pins 17 are reset.
  • Indicia 31 may be provided on the inner end of the pins 17 to identify the position of the slots 27 when setting the combination. Detent means are provided for retaining the pins in their various axial positions. Indicia 32 may also be provided on the front of the casing in order to identify individual pins.
  • a front plate 12 can have threaded apertures (not shown) which can receive the ends of set-screws passing through the door from the inside.
  • studs can extend from the plate 12 and be engaged by nuts on the inside of the door.
  • Fig. 3 illustrates a variation of the lock 10.
  • Plate 24 is a simple annulus and the rear of the lock comprises a closing plate 33 to which a plug 34 is securable by screws 35.
  • An annular groove 41 in plug 34 accommodates a resilient ring 36 against which bears one of two concave surfaces 37 forced in a rear part of each of pins 17.
  • a second resilient ring 38 surrounds the rear parts of pins 17.
  • the screws 35 are removed and plug 34 detached.
  • the desired pins 17 can now be rotated to be part of or out of the group of selected pins 17a.
  • the plug 34 is now replaced.
  • a bolt operating tongue 39 is pivotally attached to the inner-end of plunger 14 by a split peg 40.
