Definitions

  • This invention relates to a short backset mortice lock assembly for use with a door, and a lockset including a short backset mortice lock assembly.
  • the short backset mortice lock assembly is of the kind including an actuator for retracting a latchbolt, and a lock means for controlling operation of the actuator.
  • a short backset mortice lock assembly is one type of lock assembly that is located in a mortice cavity formed in a side edge of a door panel. Openings are made from the inner side and outer side of the door to the mortice cavity, so that inner door furniture and outer door furniture can connect to the lock assembly.
  • the door furniture may include hand operable lever handle or turn knob for operating the actuator.
  • a cylinder lock(s) may also be included for controlling operation of the lock means.
  • a latchbolt is one type of bolt that is spring actuated to adopt a latching condition when, for example, the door is in a closed position.
  • the actuator may include an inner hub and outer hub, either of which can be rotated to retract the latchbolt from the latched condition. The rotation of either the inner hub or outer hub can be prevented when the lock means is in an active condition.
  • the latchbolt may have a bevelled or bull nosed head which slides over a strike located in the door jamb, as the door moves towards the closed position.
  • the latchbolt may move to the retracted position in this way irrespective of the condition of the lock means.
  • the lock means may be in an active condition and yet the door may be moved to a closed position. This can result in users being inadvertently locked in or out, which is not critical if the user has a key to operate the cylinder lock.
  • the lock can be installed in an environment where not all the users may carry keys, or at least not carry keys all of the time.
  • One such environment is a store room where it is desirable that the lock means is active when the store facility is unattended, and not necessarily active when attended. A user may access the store room, have to door inadvertently close behind them, and be locked in if the lock means is in the active condition. This is considered generally as undesirable.
  • a short backset mortice lock assembly for use with a door including a housing having a front wall and a rear wall with the front wall spaced from the rear wall by less than 50mm, a latchbolt including a head that is movable relative to the housing between an extended position whereby the head extends out a from the front wall and a retracted position where the head is substantially retracted within the housing, an actuator that is operable to move the latchbolt from the extended position to the retracted position, a lock means for controlling operation of the actuator which is adjustable between an active condition whereby the actuator is rendered inoperable to an inactive condition whereby the actuator is rendered operable, the lock means including a slide detent that slides relative to the housing between a first position and a second position when the lock means adjusts between the inactive condition and the active condition, a selector means that is adjustable between an operable condition and an inoperable condition at the front wall, when the selector means is operable movement of the latchbolt
  • the selector means may take any form and in one form it includes a selector member that engages the slide detent when the selector means is operable and the latchbolt is moved to the retracted position.
  • the selector member may interact with the slide detent in any suitable manner and the slide detent may include a lug which the selector member engages to move the slide detent between the second position and the first position.
  • the selector means includes a selector axis about which the selector member pivots when the latchbolt moves from the extended position to the retracted position.
  • the selector axis is preferably substantially perpendicular to the direction of movement of the latchbolt. It is further preferred that the selector member moves in substantially the same direction as the latchbolt moves when the selector means adjusts between the operable condition and the inoperable condition
  • the selector means includes a switch that is adjustable relative to the housing when adjusting the selector means between the operable condition and the inoperable condition. It is further preferred that the selector means includes a switch biasing means so as to render the switch bi-stable, whereby the selector means is urged to adopt either the operable condition or inoperable condition.
  • the housing includes a side wall with the switch being substantially aligned with said side wall.
  • the housing preferably includes a base and a cover attached to the base, said side wall forming part of the base.
  • the housing preferably includes a base plate and the side wall of the base includes an aperture to accommodate the switch, the base plate being attached to the base so as to occlude the aperture in the side wall of the base.
  • the base is preferably formed with a rebate to accommodate the base plate.
  • the housing preferably includes a cover plate which is attached to the cover, the cover being formed with a rebate to accommodate the cover plate. It is preferred that the rebate of the cover and base occupy no less than 30% of an outer surface of the cover and base respectively.
  • the base and cover are formed from a cast zinc alloy, and the base plate and cover plate are formed from stainless steel.
  • the use of stainless steel provides greater resistance to attack on the hosing from drilling than with the cast zinc alloy.
  • the front wall forms part of the base and includes at least one aperture through which the switch can be adjusted. It is preferred that said at least one aperture includes a first aperture and a second aperture whereby depressing the switch through the first aperture renders the selector means operable, and depressing the switch through the second aperture renders the selector means inoperable.
  • the short backset mortice lock assembly include a face plate that attaches to the front wall of the housing hindering access to the switch. This use of the face plate hinders unauthorised access to the switch.
  • the latchbolt includes a body to which the head is attached, the body engaging with the selector means when adjusting between the operative condition and the inoperative condition.
  • the body preferably includes a surface over which the selector means slides when the latchbolt moves from the extended position to the retracted position.
  • the rear wall includes a pair of recesses, the slide detent having a sprung detent which locates in either one of said recess when the slide detent adopts the first position or second position.
  • a lock set for use with a door including a short backset mortice lock assembly as herein before defined, outer door furniture and inner door furniture for installation on an inner side of the door and an outer side of the door which interacts with the actuator when installed, and at least one cylinder lock assembly which interacts with the lock means.

  • the outer door furniture 4 includes an outer rectangular shaped escutcheon 16, an outer lever handle 17 and an outer cylinder lock assembly 18. Again, when the outer door furniture 4 is installed the outer cylinder lock assembly 18 is located in an opening 19 formed in the outer escutcheon 16.
  • the inner lever handle 13 and outer lever handle 17 are each rotatable about an actuator axis XX so as to rotate an inner spindle 20 and outer spindle 21 respectively.
  • the inner spindle 20 and outer spindle 21 interact with an actuator 22 of the short backset mortice lock assembly 2, only a portion of which is visible in Figure 1.
  • the actuator 22 will be described in greater detail with reference to later illustrations. It should be appreciated that the inner handle 13 and outer handle 17 illustrated are merely one preferred form of hand operable member suitable for rotating the inner spindle 20 and outer spindle 21 respectively.
  • the inner handle 13 and outer handle 17 may be replaced by a turn knob or the like.
  • the inner cylinder lock assembly 18 and outer cylinder lock assembly 14 each include a casing 23, and a barrel 24 (only the barrel 24 associated with the inner cylinder lock assembly 14 is visible in Figure 1 ) which is rotatable within the casing 23 by inserting the appropriate key (not shown).
  • a cam 25 (only a cam 25 on the outer cylinder lock 18 is visible in Figure 1 ) is attachable to the rear of the barrel 24 so as to rotate with the barrel 24.
  • the cam 25 interacts with features of the short backset mortice lock assembly 2 in a manner which will be described in greater detail by reference to later illustrations. It should be appreciated however that the shape of the cam 25 may vary from that illustrated in Figure 1 depending on features within the short backset mortice lock assembly 2 that are to be interacted with.
  • Figure 1 suggests pin tumbler cylinder lock assemblies 14, 18, the invention may also be suitable with other forms of cylinder lock assembly.
  • the housing illustrated in Figure 1 has the cover 7 and cover plate 9 to be attached to the base 6 by four screw fasteners 26.

This enables the base plate 8 and cover plate 9 to be attached to the base 6 and cover 7 respectively without increasing the overall thickness of the short backset mortice lock housing 5. Whilst the size of the rebates 29, 30 illustrated in Figure 1 occupies well over 95% of the outer surface area of the cover 7 and base 6, it is preferred that the rebate occupy at least 30% of the outer surface area of the cover 7 and base 6.
  • the housing 5 may be formed from any suitable material, it is preferred that the base 6 and cover 7 be formed as a casting, most preferably from a zinc alloy.
  • a zinc casting is preferred as it allows for various structural features to be relatively easily formed to accurately locate and accommodate internal elements of the short backset mortice lock assembly 2.
  • the base plate 8 and cover plate 9 be formed from a relatively hard metal, most preferably stainless steel, as this is more difficult to penetrate if the lock comes under attack by a drill. This enhances the security rating of the short backset mortice lock assembly.

However it can be appreciated from Figure 1 that the front wall 31 of the base 6 includes a pair of apertures 32 adjacent a side wall 34 of the base 6. Access to these apertures 32 will be prevented once the face plate 27 is attached to the housing 5, thereby hindering access to the selector means 33.
  • the invention includes a latchbolt 35 including a head 36 that is moveable relative to the housing 5 between an extended position whereby the head extends out from the front wall 27 of the housing and a retracted position whereby the head 36 is substantially retracted within the housing 5.
  • the latchbolt 35 may take any form and Figure 2 illustrates a preferred form of latchbolt assembly 35 having bevelled head 36 and body 37.
  • the shape of the head 36 may vary from that illustrated, as for example, the head 36 may instead have a bullnose shape.

Rotation of either the inner hub 40 or outer hub 41 will result in rotation of an actuator arm 43 positioned between the inner hub 40 and outer hub 41 , again rotatable about the actuator axis XX.
  • the actuator arm 43 engages the body 37 of the latchbolt 35, and further rotation of either the inner hub 40 or outer hub 41 results in movement of the body 47 towards the rear wall 39.
  • the actuator 22 also includes an actuator biasing means 44, which is illustrated in Figure 2 in the preferred form of a spring, for urging the inner hub 40, outer hub 41 and actuator arm 43 to return the position illustrated in Figure 2.

  • Figure 3 illustrates the dead latch mechanism in an inactive condition whereby the foot 53 can slide horizontally within the slot 54. Movement of the dead latch member 50 up from the position illustrated in Figure 3 locates the foot 53 against abutment 55 in the side wall 34 of the base 6, preventing retraction of the latchbolt 35.
  • the dead latching mechanism 49 can be adjusted to an inactive condition by either the auxiliary bolt 45 being in the extended position, the actuator 22 operating to retract the latchbolt 35, or the cam 25 rotating relative to the cylinder lock assembly 18 to retract the latchbolt 35.
  • the form of dead latching mechanism 49 illustrated is merely preferred, and the invention is not limited to the form of dead latching mechanism 49 as illustrated.
  • the short backset mortice lock assembly 2 includes a lock means 56 for controlling operation of the actuator 22 which is adjustable between an active condition whereby the actuator 22 is rendered inoperable, and an inactive condition whereby the actuator 22 is rendered operable.
  • the lock means 56 includes a slide detent 57 that slides relative to the housing 5 between a first position and a second position when the lock means adjusts between the inactive condition and the active condition.

  • the slide detent 57 may be moved from the first position by rotation of the cam 25 of the outer cylinder lock assembly 18 (or the cam 25 of the inner cylinder lock assembly 14, see Figure 3) to lower the slide detent 57 to the second position as illustrated in Figure 6. Whilst the slide detent 57 could interact directly with the actuator 22, it is preferred that the slide detent 57 interact indirectly with the actuator 22 by way of an inner pawl 58 and an outer pawl 59. Each of the inner pawl 58 and outer pawl 59 are independently rotatable about a pawl shaft 60 to adopt a latch condition (see Figure 5) and a release position (see Figure 8).
  • the short backset mortice lock assembly 2 includes the selector means 33 that is adjustable between an operable condition and inoperable condition at the front wall 31.
  • the selector means 33 When the selector means 33 is operable, movement of the latchbolt 35 to the retracted position prevents the lock means 56 remaining in the active condition, and the selector means 33 is associated with the slide detent 57.

If the inner pawl 58 or outer pawl 59 is in the deactivated position this leaves the respective inner hub 40 or outer hub 41 free to rotate to retract the latchbolt 35.
  • the slide detent 57 includes a ball detent 69 which interacts with a pair of recesses 70 formed in the rear wall 39.
  • Figure 8 illustrates the ball detent 69 in the upper of the two recesses 70 so as to retain the slide detent 57 in the first position.
  • a short backset mortice lock assembly will include a housing that is less than 50mm from the front wall 31 to the rear wall 39, and more generally within the range of 20mm to 50mm.
  • a short backset housing is more suited for location within a door 11 having limited capacity for developing a mortice cavity 10.
  • the portion of door 1 1 for forming the cavity may be an extruded metal sections often used in security screen doors, or sliding doors. These metal sections forming the frame of the door 11 often have a smaller depth than for example timber doors, which makes the short backset mortice lock assembly 2 more suited to this type of door 1 1.
  • the short backset mortice lock assembly 2 provides a relatively simple anti-lockout function within the confines of a short backset mortice lock assembly.
  • the utilisation of an opening in the side wall of the base for the selector means provides a unique space saving advantage.
