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said at least one slide plate will slide in one direction and vice-versa, a bolt movable with the slide plate between a withdrawn inoperative position and and extended locking position, means associated with said at least one slide plate and bolt for removably supporting a bolt stud so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.

Abstract
Description
- 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.
- With sliding doors and windows, security has always been a problem and there is now a requirement for 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. Ideally, to achieve this multi-point locking, 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. With the mechanism of the present invention, head and sill bolts and two locking devices can be provided, all activated by the same mechanism.
- According to the present invention, we provide 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.
- Preferably, 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.
- Preferably, 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.
- Preferably, 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.
- Preferably, 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.
- Preferably, 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.
- Preferably, 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.
- Preferably, 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.
- Preferably, 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.
- A preferred embodiment of locking mechanism according to the invention is now described by way of example with reference to the accompanying drawings, in which:-
- FIGURE 1 is a side elevation of the mechanism showing a head and sill bolt in a locking position;
- FIGURE 2 is a front elevation corresponding to Figure 1 but with a front plate removed and showing a pair of lock studs mounted on the mechanism;
- FIGURE 3 is a view similar to Figure 2 but showing the mechanism in an unlocked position;
- FIGURE 4 is a view corresponding to Figure 2 but with a front drive plate removed and showing a locking cylinder and lock plate in a locking position, and
- FIGURE 5 is a front elevation of the assembled mechanism corresponding to Figure 3.
- Referring to the drawings, the mechanism includes a
drive pinion 1 rotatably supported between afront plate 2 and a rear plate 3 by means ofstepped hubs drive teeth 33 spaced apart around its circumference, the spacing corresponding approximately to the width of each tooth. The front andrear plates 2 and 3 are held in spaced relationship by suitable stepped fixingrivets 34 which themselves are hollow and havetransverse bores 35 therein to assist with fixing the mechanism in a door stile. - 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 ofthefront plate 2 and having apertures therein to accommodate thestepped boss 32 and therivets 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 ofapertures 36 therein for meshing engagement with theteeth 33 on thepinion 1 so as to provide what is in effect a rack and pinion. Obviously, 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 ahandle 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 thepinion 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. - At its end remote from its meshing engagement with the
pinion 1, the plate 5 has a bolt rod carrier orblock 7 connected thereto with which asill bolt 15 is screw-threadedly engaged so as to be adjustable relative thereto. A transverse internally threadedbore 37 is also provided in thecarrier 7 optionally to receive abolt stud 9 having an enlargedhead 38. Thebolt stud 9 has an external screw-thread for engagement in thebore 37 and theamount by which it projects from thecarrier 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 afriction pad 39 which interrupts the screw thread in thebore 37 in known manner. A similarbolt rod carrier 6 is supported on the slide plate 4 at its end remote from its meshing engagement with thepinion 1 and this adjustably supports ahead bolt 16 and abolt stud 8 in a similar manner to thebolt 15 andstud 9. Of course, both the head andsill bolts carriers - Each of the
bolt studs - 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. As is customary, the locking cylinder has acam 40 associated therewith and this is arranged to co-operate with a turned overend portion 41 of alock plate 10 which itself is slidably supported on thehub 32 of thepinion 1, there being anelongated aperture 42 in theplate 10 for this purpose. Projecting into this aperture from the peripnery thereof is alug 43 which can engage in arecess 44 in thepinion 1 when the pinion has been rotated to a bolt locking position. Alternatively, thelug 43 may be replaced by a different shaped lug which can be engaged between theteeth 33 on thepinion 1. At its end opposite the turned overportion 41, thelock plate 10 has a pair of spaceddetents 45 therein, one of which can be engaged by a nose on aleaf spring 21 when the lock plate is in its released position and the other of which is engaged by the nose on thespring 21 when the lock plate is in its locking position. Also in this end of theplate 10 is anaperture 46 which may be engaged by the free end of an interior locking snib 11 which is provided if thelocking cylinder 17 is only provided with an external key aperture. In this case, the locking snib 11 would be pivotally mounted in known manner by means of anaxle 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. As can be seen from Figure 1, the locking snib is moved from its broken line position to its full line position to move the lock plate into a deadlocked position. - It will thus be appreciated that 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 bolt studs bolt studs heads 9. - It will be appreciated that if a door or window to which the locking mechanism of the present invention has been fitted has been opened and, inadvertently, the person opening the window has operated the lock so that it is in a locking position, the head and sill bolts and two bolt studs will be in a position in which they project from their respective edges of the door. If the door is then inadvertently slammed shut, damage could be caused either to the locking mechanism or to the keeper plates fitted to the door frame. This problem can be overcome with the locking mechanism of the present invention merely by providing ramps on the keeper plates for the head and/or sill bolts. This then means that if the door is slammed, as the head and/or sill bolt(s) strikes the ramp of its keeper plate, the head and/or sill bolt will be moved axially inwards towards the lock mechanism at the same time withdrawing the bolt studs into the mechanism. As a result, no damage occurs. This is a further advantage of the mechanism of the present invention which is not present in many multi-point locking mechanisms.
- In some instances, 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.
- Referring to Figures 2 to 4, it will be noted that 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 arectangular crossbar 61, the reducedcircular ends 53 of which are slidable inslots 55 in the front andrear support plates 2 and 3. Theplunger 51 is biassed to its projecting position (Figure 3) by acoil spring 59. Each end ofcrossbar 61 is arranged to be accommodated in an L-shaped slot 63 in each slide plate 4 and 5. Theslots 63 have theirlonger limb 65 extending parallel to the direction of movement of the slide plates 4, 5, and theirshorter limbs 67 extending normal to this direction. - It will thus be appreciated that when the door or the like is closed, the tip of
plunger 51 will bear against the door jamb (shown at 69 in Figure 4). Thelimb 65 is wider thancrossbar 61 to allow for tolerances between the door andjamb 69. If the door is locked, the mechanism will be as shown in Figure 4. - To open the door it must first be unlocked so as to move studs 9.to their unlocked position (Figure 3). This will cause the slide plates 4, 5 to be moved to their Figure 3 position, with the
crossbar 61 at the junction of thelimbs slot 63. When the door is opened, away fromjamb 69,spring 59 will cause theplunger 51 to move to its extended position, this being possible becausecrossbar 61 can move into thelimbs 67 of theslots 63. Once in these limbs 67 (see Figure 3), they will lock the slide plates 4 and 5 against inadvertent (or.intentional) movement to their locking position, and hence thestuds 9 cannot be moved to a position in which, if the door was slammed shut, they would damage their keeper plates. - Once the door is slammed or shut, however, the tip of the
plunger 51 will engage thejamb 69, thus causing thecrossbar 61 to move out of thelimb 67, to its junction withlimb 65 and this will then allow the slide plates 4 and 5 and hencestuds 9 to be moved to their locking position (Figure 4).
