Definitions

  • the present invention relates to electrically-operable locks such as may be used e.g. for the remote control of passage through doorways into offices or other premises.
  • the invention is concerned with an electrically-operable lock for controlling access through a doorway of the kind (hereinafter referred to as "of the kind stated") which comprises: a lock assembly for mounting to a door and a keep assembly operatively associated therewith for mounting at a location adjacent to the door; the lock assembly including bolt means adapted to extend from the door into said keep assembly; the keep assembly including a keep member displaceable transversely of the path along which the bolt means move when the door opens between a first position in which the keep member blocks said path to restrain the bolt means from such movement and a second position in which the keep member frees the bolt means from such restraint; and an electrically- energizable device coupled to said keep member for displacing the same from its first to its second position.
  • a lock of the kind stated is known from GB-A-2096687 in which the lock assembly has a single bolt extending into a keep assembly with a channel-shaped keep member which can be raised to free the bolt by energization of an associated solenoid. It is desirable in a lock of such form to have a bolt with an appreciable depth, in order to resist more. securely the loads which may be applied in an attempt to force the door to which the lock is fitted. This does, however, cause certain problems in the design of the lock because the deeper the bolt the greater is the distance through which the keep member must move in order to free the bolt and the greater, therefore, is the stroke of the solenoid required to lift the keep member.
  • the present invention seeks to overcome the aforesaid drawbacks or potential drawacks of the prior art and accordingly provides a lock of the kind stated which is characterised in that the bolt means comprises a plurality of discrete bolt members spaced apart in a direction transverse to the paths along which those members move when the door opens and that the keep member has a wall which serves to block the paths along which the bolt members move when the door opens when the keep member is in its said first position, said wall having apertures corresponding to the bolt members to enable the bolt members to pass out from the keep member when the latter is in its said second position.
  • the first example of lock comprises a key-operated locking mechanism 1 which is mounted in a hinged door 2 and which has a bolt assembly 3, and a striker unit 4 which is mounted in the frame 5 of the door 2 to engage with the extended or shot bolt assembly 3 and thereby retain the door 2 locked closed.
  • the lock mechanism 1 in this embodiment of the invention is that of a conventional mortice lock 6 having a dead bolt 7 which, as part of the bolt assembly 3, is fitted with an extension piece 8 that provides three spaced pin-bolts 9 for engagement with the striker unit 4.
  • the striker unit 4 incorporates a fixed channel-member 10, illustrated in Figures 5 and 6, that is set perpendicularly to the general plane of movement of the bolt assembly 3 in the opening- closing swing of the hinged door 2.
  • Three slots 11 in the front upstanding wall 12 of the channel-member 10 are aligned with the three pin-bolts 9, respectively, of the bolt assembly 3, so as to allow the pin-bolts 9 to pass freely through the wall 12 upon closing or opening of the door 2 with the bolt 7 shot.
  • the keep channel-member 13 is coupled via a rod 16 to a solenoid 17 to be lifted into the upper, release position against the action of a spring 18, when the solenoid 17 is energised electrically.
  • the three pin-bolts 9 project into the keep channel-member 13. If the keep channel-member 13 is then in its lower, locking position (illustrated in Figure 5) the slots 11 are blocked by the wall 15 of the channel-member 13 so that opening of the door 2 is precluded. Opening of the door 2 remains precluded in this way until either the lock mechanism 1 is operated by means of its key to withdraw the pin-bolts 9 from engagement within the channel-member 13, or the solenoid 17 is energised to lift the channel-member 13 to its upper, release position. When the solenoid 17 is energised and the channel-member 13 is thereby lifted into the release position (illustrated in Figure 6) the slots 14 are brought into register with the slots 11. This unblocks the paths of the pin-bolts 9 through the slots 11 and consequently allows the door 2 to be opened.
  • a spring-biased catch 19 projects through a slot 20 in the rear upstanding wall 21 of the channel-member 10 and a corresponding slot 22 in the rear upstanding wall 23 of the channel-member 13. While the channel-member 13 is in its lower, locking position ( Figure 5) there is overlap between the slots 20 and 22 but only to an extent to allow a finger-element 24 of the catch 19 to project through the wall 23 into alignment with one, in this embodiment the uppermost, slot 11.
  • the striker unit 4 includes provision for opening the door 2 from the inside in the event of an emergency or other condition.
  • a pivoted lever 27 ( Figure 2) is provided at the rear of the striker unit 4 to engage, when depressed, with the rod 16.
  • Such engagement lifts the rod 16 so as to move the channel-member 13 to be latched in its upper, release position in the same manner as upon energisation of the solenoid 17, until reset by re-closing of the door 2.
  • the lever 27 pivots upon each operational movement of the channel-member 13 during normal electrical actuation of the lock, thereby providing a continual checking indication of the functionality of the lever 27 for emergency use.
  • FIG. 7 A modified form of the lock described above with reference to Figures 1 to 6 is shown in Figures 7 and 8.
  • a slotted bar 29 provides the strike abutment for the correspondingly-slotted keep channel-member 30.
  • the latching of the keep channel-member 30 is effected by a catch 31 that is located to be engaged by the middle of the three pin-bolts.
  • the middle pin-bolt 32 as shown in Figure 8, is slightly out of alignment with the upper and lower pin-bolts 33 such that it enters the keep channel-member 30 slightly in advance of them. This ensures positive release of the latch, and thereby of the channel-member 30 into its locking position. It also ensures spring-biased retention of the pin-bolts 32 and 33 fast within the channel-member 30, so as to provide a positive release action when the channel-member 30 is returned to its upper, release position.
  • the channel-member 30 is urged towards its locked position by a spring 34 that acts on an emergency-release lever 35.
  • the lever 35 as acted upon by the spring 34, bears down at its inner end 36 on a pin 37 that projects from a rod 38 which intercouples the channel-member 30 with the operating solenoid 39.
  • Depression of the lever 35 against the action of the spring 34 for emergency release of the lock brings the inner end 36 of the lever 35 into engagement with the solenoid core 40 to effect the lifting required of the channel-member 30 for latching it in its release position.
  • the cylindrical keep member 41 is coupled with the solenoid (not shown) by a rod 42 that provides for axial displacement of the member 41 from an upper, release position, in which three arcuate guide slots 43 cut in the cylindrical surface of the member 41 are aligned (through slots in a fixed casing not shown) with the three pin-bolts 44 of the locking mechanism 45, to a lower, locking position.
  • the member 41 is mounted for rotation about its longitudinal axis, and the extended pin-bolts 44 enter the slots 43 laterally upon closing movement of the door so that they urge the member 41 to rotate through ninety degrees during completion of the closing movement.
  • the pin-bolts 44 are by this rotation entered into axially-directed slots 46 in the cylindrical surface of the member 41, thereby allowing the member 41 to be displaced downwardly into its locking position in which the pin-bolts 44 are trapped within the member 41 to lock the door.
  • This downward displacement takes place under the action of resilient bias that is provided by a mechanism (not shown) that responds to the ninety-degree rotation of the member 41.
  • Energisation of the solenoid lifts the member 41 to its release position against the action of this bias, returning the pin-bolts 44 to the arcuate slots 43.
  • Movement to open the door (which may be urged by the member 41 under the action of a spring that is wound up during rotation of the member 41 upon closing of the door) rotates the member 41 back to free the pin-bolts 44 from the slots 43.
