APPARATUS FOR LOCKING A CLOSURE
The invention relates -to apparatus for locking a elosure, for example a door such as a french window or patio door whieh may be a sliding closure.
Aceording to the invention there is an apparatus for locking a closure, comprising conneetors adapted for eonneetion with respective espagnolette rods an operable means slidable in a body of the apparatus for reeiprocating the eonneetors, and a key operable deadlock device whieh is arranged to block slidable movement of the operable means to loek the apparatus.
The invention extends to a closure incorporating apparatus as hereinbefore defined.
Apparatus embodying the invention is hereinafter described, by way of example, with referenee to the aeeompanying drawings.
Fig. 1 shows schematieally a plan view of a loek with parts of the top plate removed to show the interior~
Fig.lA shows an enlarged view of part A of Fig.l;
Figs. 2 and 3 show plan and end elevational views of a gear of the lock of Fig.l;
Fig.4 shows an exploded perspeetive view of loeking apparatus of a sliding door and a striker plate arrangement for the locking apparatus, aeeording to the invention; and FigO4A shows an enlarged view of a raek deviee.
Apparatus 20 has separate eonneetors 22 and 23 in the form of raeks which are adapted as at 24 for conneetion with espagnolette rods 25 and a slidable locking means in the form of studs 26 in a housing 27 whieh studs 26 project from and are seeured t-o the raek 22, so 27 which studs 26 project from and are secured to the rack 22, so that when the racks move in the direction of the arrow X, the studs move too. me racks 22 and 23 are flat, stiff, metal strips with holes through them and are engaged with teeth of a means in the form of two parallel spaced, of which one is shown in Fig.l, gears 28, which are turned in unison on insertion of a key in a key hole 29 of a lock 30, there being the usual differ pins (not shown) for operation by the key to permit turning of the lock, a projecting shaft 31 of which engages in a bush 32 to drive the gears 2~ in unison, the gears being solid with the bush and each gear engaging in holes of both racks to drive same.
The gear 28 and racks 22 and 23 are mounted in a generally solid body 33 which is shown is supported by housing 27. me housing 27 have grooves in which the racks seat and which act as guides therefor.
The housing includes a face plate 34 with spaced key-hole slots 35 through which'heads of the studs 26 project, the enlarged parts of the slots 35 enabling the studs 26 to be passed through the face plate 34 as the studs are smaller in diameter than the diameter of the enlarged parts (which are essentially circular). The narrower part of each key-hole slot provides a guide for a limb 36 of each stud 26 which is connected to a respective rack 22 or 23. The locking arrangement 20 is set in a slot or recess in the leading edge of t'he patio door with the face of the housing 27 and face plate 3~ with the key-hole slots 35 flush with that edge, so th~t there is a gap between the rear faces (to the left in Fig.ll) of the heads of the studs 26 and the Ieading edge. A handle 37 with the key operated lock 30 is mounted on an inner face of the door ad~acent the leading edge so that the shaft 31 engages the bush 32 for turning t'he gears 28, and 'hence for raising and lowering the studs 26, and espagnolette rods 25, in unison. There is also on the inside face of the door a dead lo~k 23 which is essentially a slidable bolt which can be reciprocated under key operation to engage a 'hole of the upper rack to prevent operation of the whole locking mechanism. The door frame (not shown) includes a striker plate arrangement 39 set into a slot or recess so that key-hole slots 40 of a strike plate 41 of the arrangement are at the same vertical height as the key hole slots 35 in the face plate 34.
The strike plate 41 lies over an inter~ediate plate 42 having elongate slots 43 which have a lateral extent at least as great as the diameter of the enlarged p æ ts of the key hole slots 35, 40 and both plates 41 and 42 are secured to a base plate 44. The three striking plates 41, 42, 44 are adjusta~ly secured together as by adjustment screws 45, and the whole assembly or arrangement 39 is secured to the door frame by screws 46 passing through aligned holes 47.
The arrangement is such that when the door is slid up to the frame in the fully closed position with the studs 26 in the lower, unlocked position, the studs pass through the enlarged parts of the key-hole shaped slots 40, and into the slots 43. When the key is turned (anticlockwise in ~ig.4~ to lock the door S~lut the shafts of the studs 26 ride up the narrower parts of the key-hole slots 35 and 40 so that the heads of the studs 20 ride in the slots 43 and are 'held captive 'by the striker plate arrangement 39, the rear surfaces of the heads being caught behind the parts of the striker plate 41 flanking the narrower parts of the two key-hole slots 40.
At the same time, the racks 21 and 23 move away from one another so that the espagnolette rods 25 move upwardly and downwardly respectively to engage in upper and lower keepers. The door is thus locked shut. Turning the lock 30 clockwise (Fig.4) provides a reverse motion so the studs are aligned with the key 'hole slot enlargements, and the espagnolette rods 25 are lowered and raised respectively out o~ engagement with their keepers. The door is thus unlocked, cmd can 'be slid away from the striker plate arrangement to open the door. When it is desired to lock the door open, it is merely necessary to align the nose or leading edge of the door with the keepers 1 and 10 so that the espagnolette rods 25 can engage in a desired facing pair of three pairs of holes 2 and slots 11 so that on insertion of the Xey and turning it anti-clockwise as viewed raises the rack 22 and lowers the rack 23 to "throw" the connected espagnolette rods to engage in the respective head and cill keepers 1 and 10. On withdrawal of the key, the door is locked in the "open" position.
me apparatus thus has a Eour-point locking action.
Referring now to the dead lock 38, this comprises a slot 49 in the body 33, the slot 49 being generally rectangular and extending frcm a face so to the face plate 34, and intersecting a key hole 51 the rotational axis of which is substantially at 90 to the length of the slot 49. In the body 33 and opening into the slot 49 adjacent the face plate 34 is a blind hole 52 in which is received biassing means in the form of a coil spring 53. At the end of the spring 53 adjacent the slot 49 is a latch in the form of a ball bearing 54.
~ounted in the slot 49 is a rack device 55, which has on one face a rack 56 which is exposed in the key hole 51 and on a face opposite the rack 56 is a pair of spaced depressions or seatings 57, 58 of a size sufficient to receive the ball bearing 54O me depressions or seatings comprise with the ball hearing 54 means adapted to retain the device in a plurality of positionsO mere is also at a corner of the rack device a groove 59 which receives a projection in the slot 49, so that when the projection and groove interact, the rack device 55 is guided for movement.
mere is a key (not shown) which is adapted for meshing with the rack 56. In use, the rack device 55 is seated in the slot 49 and usually is at the base thereof, where it provides a clearance for the rack 23 as it reciprocates. me rack device 55 is retained in this lower position by the ball bearing being retained in the upper (left as viewed in Fig.4) seating 57. If however it is desired to dead lock the apparatus 20, the key is inserted in the key hole 51 and engaged with the rack 56, and turned. miS causes the rack device 55 to slide up in the slot 49 away from the face plate 24 so that the free end blocks a slot in which the rack 23 reciprocates.
The rack device 55 is retained in this position by the ball bearing 54 being now engaged in the seating 58. If an attempt is then made to operate the apparatus, the rack 23, and hence the rack 22 cannot move, so dead locking the apparatus in the closed position as shown in Fig.4.
It will be understood that the apparatus may be deadlocked in the open position too if the heads 26 are aligned with enlarged parts 35, if the rack device 55 is of such an area that it can pass through an a~erture of the rack 23.

The invention extends to a closure incorporating apparatus as hereinbefore defined.
Apparatus embodying the invention is hereinafter described, by way of example, with referenee to the aeeompanying drawings.
Fig. 1 shows schematieally a plan view of a loek with parts of the top plate removed to show the interior~
Fig.lA shows an enlarged view of part A of Fig.l;
Figs. 2 and 3 show plan and end elevational views of a gear of the lock of Fig.l;
Fig.4 shows an exploded perspeetive view of loeking apparatus of a sliding door and a striker plate arrangement for the locking apparatus, aeeording to the invention; and FigO4A shows an enlarged view of a raek deviee.
Apparatus 20 has separate eonneetors 22 and 23 in the form of raeks which are adapted as at 24 for conneetion with espagnolette rods 25 and a slidable locking means in the form of studs 26 in a housing 27 whieh studs 26 project from and are seeured t-o the raek 22, so 27 which studs 26 project from and are secured to the rack 22, so that when the racks move in the direction of the arrow X, the studs move too. me racks 22 and 23 are flat, stiff, metal strips with holes through them and are engaged with teeth of a means in the form of two parallel spaced, of which one is shown in Fig.l, gears 28, which are turned in unison on insertion of a key in a key hole 29 of a lock 30, there being the usual differ pins (not shown) for operation by the key to permit turning of the lock, a projecting shaft 31 of which engages in a bush 32 to drive the gears 2~ in unison, the gears being solid with the bush and each gear engaging in holes of both racks to drive same.
The gear 28 and racks 22 and 23 are mounted in a generally solid body 33 which is shown is supported by housing 27. me housing 27 have grooves in which the racks seat and which act as guides therefor.
The housing includes a face plate 34 with spaced key-hole slots 35 through which'heads of the studs 26 project, the enlarged parts of the slots 35 enabling the studs 26 to be passed through the face plate 34 as the studs are smaller in diameter than the diameter of the enlarged parts (which are essentially circular). The narrower part of each key-hole slot provides a guide for a limb 36 of each stud 26 which is connected to a respective rack 22 or 23. The locking arrangement 20 is set in a slot or recess in the leading edge of t'he patio door with the face of the housing 27 and face plate 3~ with the key-hole slots 35 flush with that edge, so th~t there is a gap between the rear faces (to the left in Fig.ll) of the heads of the studs 26 and the Ieading edge. A handle 37 with the key operated lock 30 is mounted on an inner face of the door ad~acent the leading edge so that the shaft 31 engages the bush 32 for turning t'he gears 28, and 'hence for raising and lowering the studs 26, and espagnolette rods 25, in unison. There is also on the inside face of the door a dead lo~k 23 which is essentially a slidable bolt which can be reciprocated under key operation to engage a 'hole of the upper rack to prevent operation of the whole locking mechanism. The door frame (not shown) includes a striker plate arrangement 39 set into a slot or recess so that key-hole slots 40 of a strike plate 41 of the arrangement are at the same vertical height as the key hole slots 35 in the face plate 34.
The strike plate 41 lies over an inter~ediate plate 42 having elongate slots 43 which have a lateral extent at least as great as the diameter of the enlarged p æ ts of the key hole slots 35, 40 and both plates 41 and 42 are secured to a base plate 44. The three striking plates 41, 42, 44 are adjusta~ly secured together as by adjustment screws 45, and the whole assembly or arrangement 39 is secured to the door frame by screws 46 passing through aligned holes 47.
The arrangement is such that when the door is slid up to the frame in the fully closed position with the studs 26 in the lower, unlocked position, the studs pass through the enlarged parts of the key-hole shaped slots 40, and into the slots 43. When the key is turned (anticlockwise in ~ig.4~ to lock the door S~lut the shafts of the studs 26 ride up the narrower parts of the key-hole slots 35 and 40 so that the heads of the studs 20 ride in the slots 43 and are 'held captive 'by the striker plate arrangement 39, the rear surfaces of the heads being caught behind the parts of the striker plate 41 flanking the narrower parts of the two key-hole slots 40.
At the same time, the racks 21 and 23 move away from one another so that the espagnolette rods 25 move upwardly and downwardly respectively to engage in upper and lower keepers. The door is thus locked shut. Turning the lock 30 clockwise (Fig.4) provides a reverse motion so the studs are aligned with the key 'hole slot enlargements, and the espagnolette rods 25 are lowered and raised respectively out o~ engagement with their keepers. The door is thus unlocked, cmd can 'be slid away from the striker plate arrangement to open the door. When it is desired to lock the door open, it is merely necessary to align the nose or leading edge of the door with the keepers 1 and 10 so that the espagnolette rods 25 can engage in a desired facing pair of three pairs of holes 2 and slots 11 so that on insertion of the Xey and turning it anti-clockwise as viewed raises the rack 22 and lowers the rack 23 to "throw" the connected espagnolette rods to engage in the respective head and cill keepers 1 and 10. On withdrawal of the key, the door is locked in the "open" position.
me apparatus thus has a Eour-point locking action.
Referring now to the dead lock 38, this comprises a slot 49 in the body 33, the slot 49 being generally rectangular and extending frcm a face so to the face plate 34, and intersecting a key hole 51 the rotational axis of which is substantially at 90 to the length of the slot 49. In the body 33 and opening into the slot 49 adjacent the face plate 34 is a blind hole 52 in which is received biassing means in the form of a coil spring 53. At the end of the spring 53 adjacent the slot 49 is a latch in the form of a ball bearing 54.
~ounted in the slot 49 is a rack device 55, which has on one face a rack 56 which is exposed in the key hole 51 and on a face opposite the rack 56 is a pair of spaced depressions or seatings 57, 58 of a size sufficient to receive the ball bearing 54O me depressions or seatings comprise with the ball hearing 54 means adapted to retain the device in a plurality of positionsO mere is also at a corner of the rack device a groove 59 which receives a projection in the slot 49, so that when the projection and groove interact, the rack device 55 is guided for movement.
mere is a key (not shown) which is adapted for meshing with the rack 56. In use, the rack device 55 is seated in the slot 49 and usually is at the base thereof, where it provides a clearance for the rack 23 as it reciprocates. me rack device 55 is retained in this lower position by the ball bearing being retained in the upper (left as viewed in Fig.4) seating 57. If however it is desired to dead lock the apparatus 20, the key is inserted in the key hole 51 and engaged with the rack 56, and turned. miS causes the rack device 55 to slide up in the slot 49 away from the face plate 24 so that the free end blocks a slot in which the rack 23 reciprocates.
The rack device 55 is retained in this position by the ball bearing 54 being now engaged in the seating 58. If an attempt is then made to operate the apparatus, the rack 23, and hence the rack 22 cannot move, so dead locking the apparatus in the closed position as shown in Fig.4.
It will be understood that the apparatus may be deadlocked in the open position too if the heads 26 are aligned with enlarged parts 35, if the rack device 55 is of such an area that it can pass through an a~erture of the rack 23.
