Definitions

  • This invention relates to a locking mechanism designed for use on horizontal sliding doors and windows but which could be used in other applications to lock a movable member in a closed position.
  • Many sliding doors e.g. patio doors, have a frame for the glass which includes a lock stile, the width of which is small in relation to the overall width of the door.
  • the minimum width of lock stile is dictated by the width of locking cylinder which is a proprietary item and in the case of hollow metal box section lock stiles, the minimum internal width of the box section for most proprietary locking cylinders is about 31ram.
  • the locking mechanism of this invention has been designed to fit into such minimum width lock stiles.
  • multi-point locking e.g. for there to be locking members provided at spaced locations around the periphery of the leading edge of the door.
  • head and sill bolts are provided but this still leaves the central leading edge portion of the door susceptible to forcing with a jemmy or other suitable object and it is preferred, therefore, that at least one further locking device is provided along the leading edge of the door at a central location.
  • head and sill bolts and two locking devices can be provided, all activated by the same mechanism.
  • a locking mechanism for use with sliding doors and the like, comprising a drive pinion mounted for rotational movement between front and rear support plates, at least one slide plate in meshing engagement with the drive pinion so that when the drive pinion is rotated in one sense, said at least one slide plate will slide in one direction and vice-versa, a bolt movable with the slide plate between a withdrawn inoperative position and and extended locking position, means associated with said at least one slide plate and bolt for removably supporting a bolt stud so that in a position of use the bolt stud extends from the mechanism in a direction extending at right angles to the bolt and a lock plate mounted for sliding movement under the control of a locking cylinder between an inoperative position and a locking position in which it prevents rotation of the drive pinion.
  • two slide plates are provided, one located on each side of the drive pinion and in meshing engagement therewith so that rotation of the pinion in one sense will cause the slide plates to move in opposite directions, there being a second bolt associated with the second slide plate.
  • a bolt rod carrier is supported on an-end of each slide plate remote from its point of meshing engagement with the drive pinion to which a respective bolt is adjustably connected, one bolt comprising a head bolt and the other comprising a sill bolt.
  • each bolt rod carrier has a threaded passage therein extending at right angles to the longitudinal axis of the bolt to receive a threaded end of a bolt stud, there preferably being a friction pad interrupting the thread in said passage to lock a bolt stud screw-threadedly engaged in the passage at any suitable adjusted position.
  • the bolt studs preferably have an enlarged head on their free end for engagement with a keep plate having keyhole shaped apertures designed for co-operation with the studs and for mounting on the frame for the door or window to which the mechanism is fitted.
  • the lock plate has an aperture therein for accommodating a boss of the drive pinion and projecting into this aperture from its periphery is a locking lug which engages in a suitable recess in the drive pinion or between its sprocket teeth, preferably only when the or each bolt is in an extending locking position.
  • the locking plate has a tail for engagement with a cam on the locking cylinder at one of its ends and at its opposite end a pair of detents engageable by a leaf spring to hold the plate in either its locking or unlocked position.
  • an aperture is also provided in this end of the plate for engagement by one end of a pivotally mounted locking snib which can be used manually to deadlock the mechanism if the locking cylinder can only be key-operated from one side, e.g. the outside.
  • the locking mechanism includes an anti-slam device to prevent the mechanism moving to a locking position when the sliding door or the like to which it is fitted is in an open position.
  • the anti-slam device may include a plunger for mounting in the same leading edge of the door' or the like in which the bolt stud is mounted, the plunger being biassed to a projecting position and having a cross pin for supporting the plunger for sliding movement in transverse slots in the front and rear support plates.
  • the cross pin is a rectangular bar which is provided adjacent each end with a reduced circular pin, the bar being slidable in a generally L-shaped slot in the or each slide plate, the shorter limb of the L-shaped slot extending transverse to the direction of movement of the or each slide plate and being so situated that when the slide plate is moved to its withdrawn inoperative position, the shorter limb is so located as to allow the plunger to move under its spring bias to its projecting position such that the rectangular bar can move from its normal position within the longer limb of its L-shaped slot into the shorter limb, the plunger thus preventing the or each slide plate from being moved to its locking position until the door is moved to a closed position, whereupon the plunger will engage a jamb for the door, and be moved back to a withdrawn position as the door moves towards the jamb, thus moving the rectangular bar out of the shorter arm of the slot so that the or each slide plate can be moved so that the bolt can be moved to a locking position.
  • the mechanism includes a drive pinion 1 rotatably supported between a front plate 2 and a rear plate 3 by means of stepped hubs 31 and 32.
  • the drive pinion has a plurality of castellated drive teeth 33 spaced apart around its circumference, the spacing corresponding approximately to the width of each tooth.
  • the front and rear plates 2 and 3 are held in spaced relationship by suitable stepped fixing rivets 34 which themselves are hollow and have transverse bores 35 therein to assist with fixing the mechanism in a door stile.
  • a pair of slide plates 4 and 5 Slidably supported between the front and rear plates 2 and 3 are a pair of slide plates 4 and 5, the plate 4 sliding against the inside surface ofthe front plate 2 and having apertures therein to accommodate the stepped boss 32 and the rivets 34, and the plate 5 being similarly mounted for sliding movement against the rear face of the rear plate 3.
  • Each of the plates 4 and 5 has a plurality of apertures 36 therein for meshing engagement with the teeth 33 on the pinion 1 so as to provide what is in effect a rack and pinion.
  • the exact construction of the rack and pinion arrangement could be different from that illustrated. It will thus be appreciated that when the pinion'1 is rotated in one sense, by operation of a handle 22, secured thereto in known manner, the plates 4 and 5 will move apart and vice-versa. As is apparent from Figures 2 and 3, rotation of the pinion 1 in a clockwise direction will cause the plates 4 and 5 to move from an extended locking position towards each other to a withdrawn unlocked position.
  • the plate 5 At its end remote from its meshing engagement with the pinion 1, the plate 5 has a bolt rod carrier or block 7 connected thereto with which a sill bolt 15 is screw-threadedly engaged so as to be adjustable relative thereto.
  • a transverse internally threaded bore 37 is also provided in the carrier 7 optionally to receive a bolt stud 9 having an enlarged head 38.
  • the bolt stud 9 has an external screw-thread for engagement in the bore 37 and theamount by which it projects from the carrier 7 can be adjusted merely by screwing the stud into or out of the carrier so as to accommodate manufacturing tolerances in the door or window and its frame in which the mechanism is fitted, and the stud is held in any adjusted position by means of a friction pad 39 which interrupts the screw thread in the bore 37 in known manner.
  • a similar bolt rod carrier 6 is supported on the slide plate 4 at its end remote from its meshing engagement with the pinion 1 and this adjustably supports a head bolt 16 and a bolt stud 8 in a similar manner to the bolt 15 and stud 9.
  • both the head and sill bolts 15 and 16 may in fact be bolt rods having actual bolt members secured to..thèir ends (not shown) remote from the carriers 6 and 7.
  • Each of the bolt studs 8 and 9 is optional and if fitted each is arranged to co-operate with a keep plate (not shown) which would be fitted to a stationary frame member.
  • This keep plate would incorporate a pair of generally keyhole shaped apertures facing in opposite directions, the large portion of each aperture having a size"sufficient to allow the heads of the studs to pass therethrough when the door or window to which the mechanism is fitted is moved to a closed position, and the narrow portion of each aperture being sufficiently wide just to accommodate the shaft of each bolt stud with the enlarged head of the bolt stud riding in a hollow space behind the keep plate when the mechanism is moved to a locking position.
  • the mechanism is designed with a deadlock facility operated by a traditional key-operated locking cylinder 17 which is held in positioh in the mechanism by a cylinder screw 18.
  • the locking cylinder has a cam 40 associated therewith and this is arranged to co-operate with a turned over end portion 41 of a lock plate 10 which itself is slidably supported on the hub 32 of the pinion 1, there being an elongated aperture 42 in the plate 10 for this purpose. Projecting into this aperture from the peripnery thereof is a lug 43 which can engage in a recess 44 in the pinion 1 when the pinion has been rotated to a bolt locking position.
  • the lug 43 may be replaced by a different shaped lug which can be engaged between the teeth 33 on the pinion 1.
  • the lock plate 10 has a pair of spaced detents 45 therein, one of which can be engaged by a nose on a leaf spring 21 when the lock plate is in its released position and the other of which is engaged by the nose on the spring 21 when the lock plate is in its locking position.
  • an aperture 46 which may be engaged by the free end of an interior locking snib 11 which is provided if the locking cylinder 17 is only provided with an external key aperture.
  • the locking snib 11 would be pivotally mounted in known manner by means of an axle 47 supported on the lock stile of the door indicated at 14 in Figure 1.
  • a handle spacer is schematically shown_at 13 and the base plate for the handle 22.is shown at 12, there being suitable apertures therein to accommodate the snib 11.
  • the locking snib is moved from its broken line position to its full line position to move the lock plate into a deadlocked position.
  • a locking mechanism is provided which is extremely compact and capable of fitting in the smallest possible door stile which will also accept a standard key-operated locking cylinder.
  • the mechanism is shown as fitted with head and sill bolts 15 and 16 and a pair of bolt studs 8 and 9, but it will be appreciated that any one or more of these may be omitted.
  • the bolt studs 8 and 9 could have different constructions, for example, they could have a hook shape rather than be provided with the enlarged heads 9.
  • the head and/or sill bolts may not be provided, in which case a further anti-slam device is provided to prevent the bolt studs which have been inadvertently moved to their locking position damaging the keeper plates if the door is slammed.
  • a plunger 51 is slidably supported, so as to project through a leading face of the door (the same face from which studs 9 project), by means of a rectangular crossbar 61, the reduced circular ends 53 of which are slidable in slots 55 in the front and rear support plates 2 and 3.
  • the plunger 51 is biassed to its projecting position ( Figure 3) by a coil spring 59.
  • Each end of crossbar 61 is arranged to be accommodated in an L-shaped slot 63 in each slide plate 4 and 5.
  • the slots 63 have their longer limb 65 extending parallel to the direction of movement of the slide plates 4, 5, and their shorter limbs 67 extending normal to this direction.
