Definitions

  • This invention relates to improvements in locks and is particularly concerned with means for increasing the throw or movement of the deadbolt of a lock.
  • the maximum longitudinal movement or "throw" of the bolt of a mortice lock is limited by the width of the lock casing.
  • the width of the casing is relatively unimportant because there is no restriction on the depth of the recess in the door which is to accommodate the lock casing.
  • the maximum width of the lock casing must be less than the width of the door style.
  • the styles of such doors have a width in the region of 100mm and the maximum overall width of lock casings which can be installed in such door styles is of the order of 75mm.
  • the maximum distance from the outside front of the casing to the axis of a cylinder for the lock is of the order of 57.0mm and the distance from the outside front of the lock forend to the said cylinder or lever key axis is commonly referred to as the backset.
  • the bolt is conventionally arranged to be driven by a cylinder cam or bolt thrower and, with a backset of only 57.0mm, the maximum bolt projection, i.e. the distance by which the bolt projects from the front of the forend when the bolt is thrown, that can normally be obtained by direct drive from a cylinder cam or bolt thrower is of the order of only 14mm. This distance is insufficient to provide a secure locking engagement in the framework surrounding the door.
  • a similar problem is encountered with deadbolts for multi-detainer mortice locks.
  • a lock has been proposed in WO95/01491 having a dead lock assembly which comprises a bolt and a drive mechanism adapted to be operated by a key, wherein the drive mechanism comprises a driving link arranged to be driven by a lever actuated by the key and arranged in turn to drive the bolt, and a quadrant for transferring the drive from the driving link to the bolt in such a manner that the movement or throw of the bolt is increased relative to the displacement of the driving link.
  • the present invention aims to provide a mortice lock which is simpler to manufacture and yet still has an increased bolt projection or throw for a given width of lock casing in order to achieve a more secure engagement with the striking plate which is fitted to the door frame.
  • a lock has also been proposed in DE2525771 which has a deadbolt assembly comprising a bolt and a driving mechanism in the form of a rotatable cam which is operated by a key.
  • a lever is pivotally mounted in the casing and is arranged to be engaged by the cam, when the bolt is driven by the cam from the unbolted to the bolted position, and to move the bolt so that additional movement is imparted to the bolt to increase its throw.
  • the lever is mounted on a pin projecting from the bolt and thus some part of the lever projects from the casing when the bolt is in the unbolted position. This is a serious disadvantage and makes this arrangement quite unsuitable for a high security lock.
  • the present invention aims to provide a lock which overcomes this disadvantage.
  • a lock for a door or the like having a casing and a deadbolt assembly which comprises a bolt and a drive mechanism comprising a rotatable cam which is adapted to be operated by a key, wherein a lever is arranged between the drive mechanism and the bolt and is so arranged that, when the lever is acted on by the drive mechanism to move the bolt from an unbolted to a bolted position, the configuration of the lever is such that additional movement is imparted to the bolt to increase its throw, the lever being pivotally mounted on a pin which is mounted in the casing and the lever being arranged to be engaged by the cam during rotation of the latter in order to move the bolt to the bolted position, the lever pivoting about the pin and increasing the lateral movement or throw of the bolt, the lever being so arranged that it plays no part in moving the bolt from the bolted to the unbolted position, characterised in that the lever engages a surface of the bolt when moving the bolt to the bolted position and in that the lever
  • a lock according to the invention comprises a casing 1 to one side of which is mounted an inner forend 3 and an outer forend 4 (not shown in Fig. 1).
  • the casing is arranged to be closed by a cover plate 2.
  • a latch bolt assembly is reciprocally mounted in the casing and comprises a latch bolt head 5 secured to a latch bolt lath 6 by screws 7 which engage in screw-threaded bores 6a in the bolt lath 6.
  • the latch bolt head 5 is urged by a spring 8 to project through an aperture 4a in the forends 3, 4 under normal conditions, the spring bearing at one end on a wall 6a of the lath 6 and at the other end against a side wall 1a of the casing 1.
  • the spring 8 is held in position by engaging pegs 9a and 9b fixed, respectively, to the wall 6a of the lath 6 and the side wall 1a of the casing 1 and engaging in the respective ends of the spring 8.
  • the lath 6 is guided for sliding movement in the casing 1 by a pin 10 which is fixed to the casing and extends through an elongated aperture 6b in the lath 6.
  • the arm 11a of a follower 11 is located between the pin 10 and the wall 6a of the lath 6, the follower being mounted on a square-sectioned spindle (not shown) extending through the casing and having a handle (not shown) fixed to at least one of its ends.
  • the follower arm 11a is provided with a peg 11b for locating one end of a spring 12 the other end of which bears against the casing wall 1a and is located there by a peg 13 which is fixed to said casing wall.
  • a spacer 14 serves to locate the follower 11 in the casing 1. Turning a handle is effective to rotate the spindle and hence the follower 11 against the action of the spring 12. Turning of the follower 11 causes the follower arm 11a to move the lath 6, against the action of the spring 8, and the lath moves along the pin 10 to retract the bolt head 5 into the casing 1. If the handle is now released, the springs 8 and 12 re-exert themselves, and force the bolt head 5 once more to project from the forends 3 and 4.
  • the lock shown in Figs. 1-12 of the drawings further comprises a deadbolt assembly including a deadbolt 15.
  • the deadbolt 15 is provided with a stump 16 which is located in an elongated slot 2a in the cover plate 2 for guiding movement of the deadbolt 15.
  • a pin 17 projects from the other side of the deadbolt 15 and is located in an elongated slot 1b in the casing 1, again for guiding movement of the deadbolt.
  • a plurality of detainers 24 and spacers 27 are pivotally mounted on a pin 26 which is fixed in the casing, each detainer and spacer having an openended slot 24a through which the stump 16 extends.
  • Leaf springs 25 fixed to each of the detainers 24 are engaged with a pin 19 in the casing 1, said springs serving to force the respective detainers into a position in which the stump 16 is engaged in respective notches 24b in each of the slots 24a in the unlocked position of the deadbolt assembly as shown in Fig. 2 of the drawings.
  • a bolt throw extension lever 18 is pivotally mounted on the pin 19 for a purpose to be hereinafter described.
  • Aligned keyhole slots 1c and 2c are provided in the casing 1 and cover plate 2 respectively and a bolt thrower 20 is rotatably mounted in the circular parts of the slots 1c and 2c.
  • a cam controller 21 is pivotally mounted on a pin 23 in the casing 1 and is arranged to be acted on by a spring 22 which is mounted on a pin 28 in the casing.
  • the spring 22 urges the cam controller 21 into engagement with the bolt thrower 20 so that the bolt thrower engages in a notch 21a in the cam controller whereby the bolt thrower is held in position in the unlocked condition of the lock as shown in Fig. 2 of the drawings. Also as shown in this figure, the deadbolt 15 is fully withdrawn in the unlocked condition of the lock.
  • a key (not shown) must first be inserted into the bolt thrower 20 through one of the keyhole slots 1c or 2c.
  • Rotation of the bolt thrower 20 in the counter-clockwise direction as indicated by the curved arrow in Fig. 2 initially causes the cam controller 21 to pivot about the pin 23, against the action of the spring 22, so that the bolt thrower 20 moves out of its engagement in the notch 21a. Further rotation of the bolt thrower will bring the key into engagement with radiussed edges 24c of the detainers 24 whereby the detainers are compelled to pivot clockwise about the pin 26, as indicated by the curved arrow in Fig.
  • the extension lever 18 is so located that as it is driven at its edge 18a by the face 20a of the bolt thrower 20, as the latter rotates, an effective straight line "throw" of 17mm is generated by the arcuate path of the edge 18a as it is propelled across the sweep of the rotating bolt thrower 20.
  • the effective straight line dimension between the edges 18a and 18b at the commencement of the action in the unlocked position is 11mm but since the angular relationship between the points of contact at 18a and 18b changes as the extension lever pivots on the pin 19, in the fully thrown i.e. locked condition, the effective dimension between the edges 18a and 18b becomes 14mm. This increase of 3mm when added to the 17mm already provided by the extension lever 18 results in 20mm of motion being imparted to the deadbolt.
  • the stump or detent block 16 being fixed to the deadbolt 15 has also moved through 20mm so that it is now clear of the radiussed edges 24c of the detainers 24 so the detainers are free to pivot, counter-clockwise urged by their springs 25, to the level where their edges 24d come to rest on the detent block or "stump" 1b and thus the deadbolt is fully arrested in the locked position.
  • the extension lever 18 is held in its correct alignment by the engagement of a notch 18c with the detent block 16.
  • the guide pin 17 being fixed to the deadbolt has reached the limit of its travel in the slot 1b in the casing, thus preventing any further leftward movement of the deadbolt.
  • Fig. 8 shows the unit in the locked condition with the bolt thrower 20 now having rotated to its full counter-clockwise extent, limited by its shoulder 20c engaging the edge 15b of the deadbolt 15 with the key exit/entry slot being in alignment with the corresponding slots 1c and 2c in the casing 1 and cover plate 2.
  • This alignment is maintained against inadvertent clockwise rotation by the cam controller 21. Urged by the spring 22 the recess 21 in the cam controller engages the face 20b of the bolt thrower 20, thus completing the sequence.
  • a key In order to unlock the deadbolt, a key must be inserted in the bolt thrower 20 and the bolt thrower turned, by means of the key, in a clockwise direction as viewed in the drawings. Turning of the bolt thrower will disengage the shoulder 20c from the edge 15b of the deadbolt as well as the face 20b of the bolt thrower from the notch 21a in the cam controller 21. Further rotation of the bolt thrower in a clockwise direction as indicated by the curved arrow in Fig. 9 will cause the flank of the key to press against the detainers 24.
  • the detainers are forced to pivot in a clockwise direction about the pin 26 until the steps on the key engage the respective detainers 24 at their specifically radiussed edges 24c and cause further pivoting of the detainers about the pivot pin 26 until the gate slots 24a are aligned with the detent block or stump 16 as shown in Fig. 10 of the drawings.
  • the deadbolt is thus no longer detained and at the same time the face 20d of the bolt thrower 20 is moved into engagement with an angled face 15c of the deadbolt 15.
  • Fig. 12 shows the deadbolt 15 in the fully withdrawn position with the angled face 15c on the deadbolt engaging the radiussed face 20b of the bolt thrower 20 and, since the guide pin 17 on the deadbolt has reached the limit of the slot 16 in the casing, the deadbolt is held in this position while the bolt thrower continues to rotate in a clockwise direction.
  • the detainers 24 are released from the lifting steps of the key and, under the action of the springs 25, they pivot in a counter-clockwise direction until the notches 24b in the slots 24a engage with the detent block or stump 16 thus holding the deadbolt in its fully withdrawn or unlocked position.
  • the cylinder operated lock shown in these figures differs from the lock shown in Figs. 1 to 12 in that the deadbolt 15 is replaced by a deadbolt assembly comprising a deadbolt head 35a and a deadbolt lath 35b.
  • a pin 37 is secured to the deadbolt lath 35b and is located in a slot 1d in the casing 1.
  • An extension lever 38 is pivotally mounted on a pivot pin 39 which is fixed in the casing 1. At its opposite extremity the arcuate path of an edge 38a of the extension lever overlaps the sweep of the operating arm or "cam" 40a of a conventional pin-tumbler cylinder unit 40.
  • the cam 40a has the same effect as the bolt thrower 20 in the detainer version, in that when throwing the deadbolt from the unlocked to the locked position the cam 40a acts against the edge 38a of the extension lever 38 and an edge 38b of the extension lever acts against a shoulder 36a on the deadbolt head 35a.
  • the cam 40a of the cylinder is rotated further counter-clockwise, as viewed in Fig. 14, the extension lever is obliged to pivot further clockwise and the changing geometry between all the points of contact delivers the required increased amount of leftward travel to the deadbolt, just as in the detainer version.
  • the deadbolt is only driven by the extension lever 38 in the action from the unlocked to the locked position, being then returned to the unlocked position by the clockwise rotation of the cylinder cam, as with the bolt thrower in the multi detainer version.
  • the cylinder 40 is retained in the casing by a screw 40h which passes through a bore 40c in a side wall 1e of the casing 1 and through an apertured guide 40e and is engaged in a screw-threaded bore 40g in the cylinder 40.
  • the guide 40e is provided with side extensions 40f which engage, respectively, in slots 1f and 2f in the casing 1 and cover plate 2.
  • the deadbolt assembly again incorporates a detent block or "stump" 36 but since the "differing" of the system is now a function of the pin-tumbler mechanism, only a single detainer 44 is needed in order to arrest the deadbolt at each end of its travel.
  • the detainer 44 is pivotally mounted on a pivot pin 46 which is fixed in the casing, a spacer 47 being located between the deadbolt lath 35b and the detainer 44 and the spacer being similarly pivotally mounted on the pivot pin 46.
  • a spring 45 acts on the detainer 44 urging it in a counter-clockwise direction so that the detent block or stump 36 engages in a notch 44b in the detainer 44 in the unlocked position of the deadbolt as shown in Fig. 14.
  • One end of the spring 45 is secured in the detainer 44 and the other end bears against a pin 45a which is mounted in the casing 1.
  • the spacer 47 is provided with a slot 47a to accommodate the detent block or stump 36 but in this case no notch is provided in the spacer.
  • the cam 40a As the cam 40a is rotated counter-clockwise in order to move the deadbolt assembly as indicated by the curved arrow in Fig. 15, it is moved into a notch 35d in the deadbolt lath 35b and bears against the detainer 44 which is thus caused to pivot in a clockwise direction to the level at which a slot 44a is aligned with the stump or detent block 36 on the deadbolt lath 35b. Once this alignment is reached, the cam 40a passes on to a specifically radiussed edge 44c of the detainer 44 so that the alignment is maintained while the deadbolt is travelling as indicated in Figs. 15 to 17 of the drawings.
  • the spring 45 is effective to urge the detainer in a counter-clockwise direction so that an edge 44d of the detainer engages behind the stump 36 as shown in Fig. 18 of the drawings.
  • a projection 44e on the detainer 44 lies inside the circular path or "sweep" of the cylinder cam 40a in order to limit the counter-clockwise rotation of the cam 40 as indicated by the dotted lines in Fig. 19, and thus prevents the detainer from being lifted inappropriately.
  • the cylinder cam 40a In order to withdraw the deadbolt to the unlocked position, the cylinder cam 40a must be rotated by a key in the cylinder 40 in the clockwise direction. In this case, the radiussed edge 40b of the cylinder cam 40a will engage the radiussed edge 44c of the detainer 44 to lift the detainer so that its edge 44d is raised clear of the stump 36. Further rotation of the cam 40a will cause it to engage an angled face 36b of the deadbolt lath 35b and cause the deadbolt assembly to be withdrawn since the stump 36 is now aligned with the slot 44a in the detainer 44. The cam 40a continues to move the deadbolt assembly to the right until the cam comes into engagement with the side of the detainer projection 44e.
  • the cam must be returned to the position shown in Fig. 14 before the key can be removed from the cylinder lock 40. However, if the key is not removed, the cylinder cam 40a may be rotated further in a clockwise direction in order to operate a cylinder-to-latchbolt linking mechanism.
  • the spacer 14 of the detainer version is replaced by an outer follower 34 having an upper projecting arm 34a and a link 34b which is provided at its end with a bore adapted to receive a pivot pin 54.
  • the follower 34 is mounted on the follower 11 but in this case the follower 34 has an arcuate cut-out 34c which engages over a projection 11c on the follower 11 which limits pivotal movement of the follower 34 with respect to the follower 11.
  • the projection 11c engages the upper end of the arcuate cut-out 34c.
  • a cylinder-to-latch link 55 is pivotally mounted on the pivot pin 54 and is provided at its lower end with a cranked portion 55a which is located in the path of the cylinder cam 40a in the unbolted position of the deadbolt. If the cylinder cam 40a is rotated further in a clockwise direction from the position in which the deadbolt assembly is fully withdrawn as shown in Fig. 14 to the position shown in Fig. 20, the cam comes into engagement with the portion 55a of the link 55. The link is located in a recessed area 35c of the deadbolt head 35a and is forced in an upwards direction by the engagement of its portion 55a by the cam 40a.
  • the cam 40a can be returned to the vertical position shown in Fig. 14 and the key withdrawn.
  • the spring 8 will act on the follower arm 34a to return it to the position shown in Fig. 20 of the drawings and the link 55 will also be returned by virtue of its connection to the outer follower 34 by the pivot pin 54.
  • the arrangement is such that, if the deadbolt has been thrown to the locked position, the cylinder-to-latch linkage does not operate.
  • the link 55 is provided with a projection 55b which lies across the path of the stump or detent block 36 so that as the deadbolt is thrown to the locked position, the stump or detent block 36 engages the projection 55b to move the link 55 out of the path of the cylinder cam 40a as shown in Fig. 22 of the drawings, the link pivoting about the pivot pin 54.
  • rotation of the cam 40a has no effect on the link 55 or on the latch bolt.
  • the deadbolt engages the link 55 to return it to the position shown in Fig. 20 in which the projection 55a is located in the path of the cylinder cam 40a.
  • the compression spring 12 acts only against the arm 11a of the latchbolt follower 11 to return the motion from the external handles via the square spindle. Since the function of the two springs 8 and 12 are partly independent the result is that the latchbolt head and the cylinder-to-latch action can be lightly sprung while the external handles/latch action may be sprung more heavily.
  • the compression spring 8 acts against the latchbolt lath 6 at its face 6a so as to return the assembly to the latched position when the manual force from the key/cylinder is released. Similarly, if a door fitted with a lock according to the invention is pushed shut, only the force of the spring 8 needs to be overcome by the movement of the latch bolt head 5 as the door is shut.
  • the pin 10 which is fixed in the casing, serves not only to guide the linear motion of the latchbolt assembly and to limit its travel but also functions as a limiting position for the arms 11a and 34a of the followers 11 and 34 respectively in the latched situation where they bear against the pin 10 under the action of the springs 8 and 12.
  • the latch bolt head 5 may be reversed in either or both of the above-described embodiments.
  • the bolt head is provided with bores 5a on both sides to accommodate the screws 7 for this purpose.
  • Apertures 2b in the cover plate 2 allow access to the screws 7 from outside the lock so that the casing does not have to be opened in order to reverse the bolt head.
  • the extension lever which enables the increased throw of the deadbolt can be used both for multi-lever detainer locks as well as with cylinder operated locks with only minor dimensional changes. Further only one additional part, namely the extension lever, is required than with most conventional locks.
