Definitions
- the present invention relates to locks of the kind in which a bolt member is engaged with a keep member of the lock to restrain the bolt member from movement in a predetermined path with respect to the keep member, and the keep member is displaceable to free the bolt member for said movement.
- Locks of the above-specified kind are known for use where passage through a doorway into offices or other premises is to be controlled remotely, and in this respect it is common to utilize a conventional key-operated or latching lock-mechanism on the door that engages its bolt within an electrically-releasable keep member in the form of a striker box on the door frame.
- a striker box on the door frame.
- Such box either pivots as a whole, or has as one of its sides a flap that pivots, under control of a solenoid mounted in the door frame.
- the bolt of the lock mechanism is retained by the striker box to preclude opening of the door until such time as the solenoid is energised electrically, whereupon the box or the flap pivots to release the bolt and thereby free the door for opening.
- any attempt to force the door open loads the pivot-mounting of the box or flap- side, together with the solenoid-operated mechanism associated with it, making the lock very vulnerable in this respect.
- a lock of said above-specified kind is characterised in that the keep member is displaceable transversely of said path between a first position in which it blocks said path to restrain the bolt member as aforesaid, and a second position in which it is clear of said path to free said bolt member for movement in said path.
- the keep member may be a member, for example a channel member, having an upstanding wall that serves to block said path when the keep member is in its first position, and in these circumstances the wall may be apertured such as to enable the bolt member to pass out from behind the wall when the keep member is in its second position. More especially the keep member in these latter circumstances may be located behind a fixed upstanding wall (provided as such or, for example, as the front wall of a channel member in which the keep member is arranged to slide) that extends across said path and is apertured to enable the bolt member to move freely in that path; the one or more apertures in the keep member will be in register with the one or more apertures in the fixed wall when the keep member is in its second position but not when it is in its first position.
- the fixed wall will provide a structural abutment for the keep member against which to resist loads applied to the keep member when it is in its first position capturing the bolt member.
- the keep member may be arranged for both angular and axial displacement such that the first and second positions are separated from one another both longitudinally and angularly with regard to such axis.
- Displacement of the keep member between its first and second positions may be effected by an electrically-energisible solenoid or by mechanical or other means.
- the bolt member of the lock may comprise a plurality of mutually-spaced pin-bolts or other discrete elements for engaging with the keep member, and may be the bolt of a key-operable lock mechanism such that it can be withdrawn by key- operation of that mechanism.
- the involvement of a key-operable mechanism is not essential and the bolt member may simply be a fixed, non-withdrawable member that engages with the keep member.
- 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.
- 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.
- 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 locking 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-directeo slots 46 in the cylindrical surface of the member 41, thereby allowing the member 41 to be displaced downwardly into its locking postion 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.
