Definitions

  • the present invention relates to locks for use on sliding wings and to certain components used on these and other kinds of locks.
  • the present invention may find particular use on sliding wings such as sliding doors and the like.
  • the invention will therefore be described primarily with reference to its application in sliding doors.
  • the invention may also be applicable to other forms of sliding wings, for example sliding windows, sliding panels etc, and other keyed locks.
  • Locks and latches for sliding wings such as sliding doors are quite common. Some are relatively simple. For example, latches which incorporate little more than a hand operated lever on the inside of the door are in widespread use. With these latches, operating the lever typically causes a hook shaped latch tongue (often called a "parrot beak") to rotate out from the front edge of the door. Consequently, when the door is closed and the lever is operated, the parrot beak rotates out of the edge of the door and engages with a strike or keeper in the doorframe thereby securing the door to the doorframe (i.e. latching the door closed). The lever can also be used to disengage the parrot beak allowing the door to be opened. However, these kinds of simple sliding door latches are quite insecure.
  • the parrot beak(s) can be rotated to lock the door using either the lever or the key cylinder. If the door is simply
  • the lever and the key cylinder can also both be used to unlock the door by retracting the parrot beak(s), thereby allowing the door to be opened.
  • the lock is "deadlocked”, it generally is not possible to retract the parrot beak(s) using the lever. Consequently, the key cylinder must be operated to undeadlock the lock if the door is to be opened.
  • sliding door locks being "handed".
  • a sliding door or other sliding wing will be described as left-handed if it slides open from right to left as viewed by the person opening it.
  • the wing will be described as right-handed if it slides open from left to right. Consequently, in sliding wings such as sliding doors which can be opened from either side, one side will be left-handed and the other side will be right-handed.
  • a lock that is designed to be installed on the left-handed side of the door or wing will be described as a left-handed lock
  • a lock designed to be installed on the right-handed side will be described as right-handed.
  • a lock could be provided for sliding wings which could be configured for use as both a left handed and a right handed lock. It would be particularly advantageous if such a lock could be converted between the two "handednesses" without requiring substitution of any parts for alternative parts in performing the conversion. This would enable a single lock to be sold and then configured for the appropriate handedness, without requiring alternative parts for each different handedness, or any adapters etc. It would also be advantageous for the lock to be of the more secure variety having a key cylinder, particularly if the key cylinder of the lock could be turned in the conventional directions (i.e. a conventional direction to lock the lock and a conventional opposite direction to unlock the lock) irrespective of which handedness the lock is in.
  • Maintaining conventional key turning directions for the left and right handednesses of the lock would be preferable because users often become accustomed to turning the key one way to lock the lock and the other way to unlock the lock. For instance, in many locks it is conventional for the top edge of the key (i.e. the edge of the key that faces upwards when the key is inserted into the key cylinder) to be rotated from its insertion position towards the front edge of the door to lock the lock, and in the opposite direction to unlock the lock. If the key turning directions were conventional for one handedness of the lock but opposite to the convention for the other handedness, this could cause inconvenience to the user when the lock is in the handedness with the unconventional key directions. It could also create danger, for example in the case of an emergency where the lock must be operated quickly but the user is unsure which direction to rotate the key to unlock the lock.
  • the end of the key cylinder inside the lock i.e. the opposite end of the key cylinder's barrel to where the key is inserted
  • the posts are generally located at diametrically opposed locations on the circumference of the round inside end of the key cylinder barrel.
  • the component inside the lock which engages with the end of the barrel generally has a bar or some other entraining member which becomes positioned between the posts when the lock is assembled. Therefore, when the key is turned in the cylinder in one direction (which causes the key cylinder barrel to rotate that way), one of the posts collides with one end of the bar and the other post collides with the other end of the bar.
  • lost motion of approximately 90° of the key cylinder barrel is quite common.
  • it is quite common to be able to rotate the barrel approximately 90° without operating the internal components of the lock hi order to increase the amount of lost motion, it has previously been proposed to reduce the size of the posts on the barrel, and hence increase the amount of possible rotation before the posts contact with the bar.
  • the increase in the amount of available lost motion achieved in this way is quite small (generally far from reaching 180°), and reducing the size of the posts can reduce the strength and durability of the posts.

In this way, if the lock is flipped over to be used as a left-handed lock rather than a right-handed lock (or vice-versa), the shape of the furniture and the handle in the inverted configuration will be a mirror image of its shape in the un-flipped configuration. So, the shape of the furniture and handle may be mirrored, but otherwise consistent in either configuration.

  • the lock tongue will also preferably be in the form of a rotating parrot beak. Therefore, the lock operating component may engage with the parrot beak in such a way that the linear movement of the operating component between the first and second positions causes rotation of the parrot beak between the unlocking and locking positions respectively.
  • One way that this may be achieved is for the operating component to engage with the parrot beak at a point on the parrot beak that is offset from the parrot beak's axis of rotation.

  • providing a pair of opposing parrot beaks may help to prevent the door from simply being lifted to disengage the lock from the strike as described in the background section above.

So that the movement of the operating component in one direction causes one beak to rotate one way and the other beak to rotate the other way, the lug on one of the beaks should be offset to one side of the axis of rotation, and the lug on the other beak should be offset to the other side.

  • the snib and the drive component can both be used to unlock and lock the lock tongue by moving the operating component between the first and second positions.
  • the exception to this is when the lock is deadlocked, and this occurs when the drive component is moved into the deadlocking position. Moving the drive component into the deadlocking position causes the operating component to be held in the second position so that the operating component cannot be moved from the second position to the first position by the snib.

This is so that, when the drive component is rotated in one direction, the cam moves upwards even though it is constrained to rotate about the drive component's axis of rotation. In other words, the positioning of the cam on the side of the drive component may allow the cam to move in an upwardly arcing path when the drive component is rotated one way. Similarly, when the drive component is rotated the other way, the cam may move downward (in a downwardly arcing path).

  • Rotation of the rotating drive component in the other direction may cause the cam to push up on the other edge of the operating component, forcing the operating component to slide upwards in the lock.
  • the operating component may be slid downwards to adopt the first position (to unlock the lock tongue(s)), and upwards to adopt the second position (to lock the lock tongue(s)), or vice versa.
  • the direction that the rotating drive component will need to be rotated to drive the operating component up and down will depend on whether the cam is on the left-hand side or the right-hand side of the drive component. For the purposes of explanation, consider a configuration where the operating component is slid downwards to adopt the first position (to unlock the lock tongue(s)), and upwards to adopt the second position (to lock the lock tongue(s)). Hence, rotating the drive component from the lock opening position to the lock closing position will drive the operating component upwards from the first position to the second position.

Consequently, the force would have no directional component which would tend to rotate the cam back towards the lock closing or lock opening positions. Therefore, in order to be able to unlock the lock using the snib, the drive component itself must first be rotated back to the lock closing position (or at least back out of the deadlocking position) whereupon downward forces imparted on the lock operating component by the snib would tend to urge the cam to move in its arcing path around the drive component's axis of rotation.

  • the other end of the elongate entraining member may have an entraining lug which protrudes out from the end of the barrel even further than the other parts of the entraining member.

  • the entraining lug on one end of the barrel's entraining member may insert into the through- bore in the drive component.
  • the drive component's cylindrical portion may become positioned beside the barrel's protruding entraining member. Consequently, rotating the barrel in one direction will cause the wider wedge shaped end of the entraining member to contact with the wedge- like tab on the drive component (the sloping sides of the wedge shaped end of the entraining member may have a similar slope to the sloping sides of the wedge-like tab so as to allow close mating contact between the two), and at the same time the entraining lug may contact with the ridge inside the drive component's through bore. This may then cause the drive component to rotate in the same direction as the barrel.
  • the lock may incorporate means for providing an indication to the user when the drive component reaches one or more (or each) of the respective lock opening, lock closing and deadlocking positions.
  • a number of ways of providing such an indication are possible. For example, some embodiments may provide an audible "click" or other sound when the drive component reaches a particular position (for example, to indicate that the lock has adopted one of the opened, locked or deadlocked modes).
  • Other embodiments may utilise visual indicators (such as a window in the lock body that shows green, yellow and red for the lock opening, lock closing and deadlocking positions of the drive component respectively).
  • embodiments of the invention may more commonly utilise a mechanism that allows the user to physically feel when the drive component reaches one 21
  • a spring and roller arrangement may be used.
  • the spring may be a linear spring (such as a coil spring or a compressible rubber member etc).
  • One end of the spring may be mounted to the lock body (or the cassette), and the roller may be positioned for rotation on the other end of the spring.
  • the roller may comprise a ball bearing.
  • the ball bearing may engage with the outer surface of the drive component. Hence, rotation of the drive component may cause the ball bearing to roll along the drive component's outer surface.
  • the outer surface of the drive component may be provided with one or more indents.
  • an indent may be provided for each of the lock opening, lock closing and deadlocking positions of the drive component.
  • the ball bearing may be forced into the indents under the force of the spring.
  • the insertion of the ball bearing into the indent may provide a slight resistance to the further rotation of the drive component which will be felt by the user as they operate the key or the snib.
  • the resistance to further rotation provided in this way may be easily overcome by the user. So the user can continue to turn the drive component which results in the ball bearing being forced back out of the indent and continue rolling along the outer surface of the drive component. Nevertheless, the insertion of the ball bearing may provide a physically felt indication when the drive component is in one of the said positions.
  • the lock may also be provided with an "anti-slam” mechanism.
  • An anti-slam mechanism is a mechanism that retains the lock tongue(s) in the unlocking position until the door is fully closed with the lock in engagement (or at least very close proximity) with the strike or keeper. This prevents the lock tongue(s) from being moved into the locking position before the door is closed, and therefore helps alleviate the risk of the door being slammed into the keeper with the lock tongue(s) already in the locking position causing damage to the lock and/or keeper. Therefore, the anti-slam mechanism operates to prevent the snib or the key cylinder from being used to move the lock tongue(s) into the locking position until the door is fully closed. After the door is properly closed, the snib and/or the key can be used to operate the lock as described above.
  • the lock may be provided with a deadlock indicator. This could be in addition to the above-mentioned means for providing a positive indication to the user when the drive component reaches one or more (or each) of the respective positions.
  • the deadlocked indicator may provide a visual indication to the user when the lock is deadlocked. This is so that the user can identify at a glance that the lock is deadlocked. This may be particularly useful in the case of fire or some other emergency when it is necessary to operate the lock very quickly. By providing a visual indication as to whether or not the lock is deadlocked, the user can determine at a glance the action required to unlock the lock without needing to fiddle with the lock to first determine which mode the lock is in.
  • the deadlocked indicator could take a wide variety of forms.
  • the window in the lock body mentioned above that shows green, yellow and red for each of the respective drive component positions would function as a deadlocked indicator.
  • the deadlock indicator may operate to provide a positive indication to the user when the lock is deadlocked, whichever handedness the lock is in.
  • the deadlocked indicator may comprise a tab which extends visibly out from the lock body when the lock is deadlocked, but which is retracted into the lock body out of sight when the lock is not deadlocked (i.e. the tab is retracted at all times when the lock is operable by the snib).
  • the deadlock indicator mechanism may incorporate an elongate component inside the lock. The elongate component may be biased towards the retracted position so that the tab (which may connect with the elongate component) only extends out of the lock furniture when it is driven out by deadlocking the lock, and so that the tab immediately retreats back inside the lock body when the lock is un-deadlocked.
  • the elongate component may be configured to slide up and down within the lock.
  • the elongate component may be mounted in the cassette and it may slide up and down within the cassette. Providing the elongate component in the cassette may provide the benefit that the orientation of the elongate component relative to the door when installed on the door remains the same for either handedness of the lock, 23
  • the elongate component may engage with the cam on the drive component when drive component rotates into the deadlocking position. Hence, rotating the drive component into the deadlocking position may drive the elongate component up (or down) in the lock forcing the tab to project out from the lock furniture.
  • the lock furniture may be provided with an aperture through which the tab can extend when the lock is deadlocked.
  • the furniture may have a pair of apertures (typically one in either end) to allow the tab to extend out, whichever handedness the lock is in.
  • the invention resides in a lock for a sliding wing comprising a parrot beak rotatable between a locking position and an unlocking position to lock and unlock the wing respectively, a rigid operating component which is slidable in a linear fashion between a first position and a second position and which can engage with the parrot beak at a point on the parrot beak offset from the parrot beak's axis of rotation such that sliding the operating component into the first position causes the parrot beak to rotate into the unlocking position and sliding the operating component into the second position causes the parrot beak to rotate into the locking position, and a key operated drive component that can engage with the operating component and which is moveable between an opening position and a deadlocking position, wherein moving the drive component into the opening position causes the operating component to adopt the first position and moving the drive component into the deadlocking position causes the operating component to adopt the second position.
  • the invention resides in a lock that can be converted from one handedness to the other handedness, the lock comprising lock furniture that can be inverted when converting the lock from one handedness into the other, a casing within which internal components of the lock can be mounted, the casing being mountable to the furniture but also removable and re-mountable to the furniture in an inverted orientation whereby when the lock is installed the orientation of the casing can be the same whichever handedness the lock is installed in, and a key cylinder mountable to the 24
  • the invention resides in a lock having a lock tongue movable between a locking position and an unlocking position, a drive component in the lock that can be rotated to cause the lock tongue to move between the locking position and the unlocking position, and a key cylinder for rotating the drive component, the key cylinder being configurable to engage with the drive component from either side of the drive component, wherein the engagement between the key cylinder and the drive component allows over 180° of lost motion of the key cylinder whichever side of the drive component the key cylinder engages from.

  • Figure 11 is a close-up perspective illustration of the internal end of the key barrel and the drive member.
  • Figure 1 shows a cassette 10 having a cover 11.
  • the cassette 10 provides a hollow casing inside which the other components shown in Figure 1 can be mounted.
  • the cover 11 can be secured over the open side of the cassette using screws, rivets etc to close the cassette.
  • Figure 2 shows the external furniture of the lock in a right-handed configuration.
  • the furniture incorporates an elongate box-like main body portion (the "body") 30, and a handle 32 extending in an arc shape from the top to the bottom of the body 30. Because 26
  • the handle 32 extends out to the right of the body so that when the lock is installed on a right-handed door, the front edge of the furniture 30' (hidden on the left in Figure 2) will line up approximately flush with the front edge of the door.
  • the body 30 and the handle 32 are symmetrical about the horizontal centre line A-A in Figure 2. Consequently, if the lock furniture were to be flipped over to be used as a left-handed lock (i.e. with the handle 32 extending out to the left) rather than as a right-handed lock as shown, the shape of the furniture and the handle in the inverted configuration would be a mirror image of the shape shown in Figure 2.
  • Figure 3 demonstrates the way the casing 10, with the internal components of the lock mounted therein, can be inserted into the main portion 30 of the body. This is indicated by the dashed lines. It will also be appreciated that the cassette 10 can be readily removed from the main portion 30 of the body. When converting the lock from one handedness to the other, the casing may be removed and inverted (i.e. rotated 180° as indicated by the arrows "B") and then reinserted. In this way, the orientation of the cassette relative to the door when the lock is installed remains the same, even though the orientation of the furniture is flipped to swap the handedness of the lock.
  • the opening in the main portion of the body of 30 where the casing 10 is inserted should therefore be shaped to receive the cassette 10 in either of these configurations. The opening for receiving the cassette is not shown in the drawings.
  • Figure 3 also illustrates a snib link member 17 and an external snib button 17a, as well as illustrating key cylinder 36 more clearly.
  • the key cylinder 36 can be removed, inverted and reinserted so that the key cylinder is oriented "key slot down" in both the left-handed and the right-handed configuration of the lock.
  • the circular aperture 302 in the body 30 which receives the key cylinder 36 has two box- shaped gaps, one extending above aperture 302 and one extending below it.
  • gap 303 can just be made out in Figure 3.
  • the purpose of the gaps is to receive the box shaped portion 362 of the key cylinder which contains the key cylinder's split pins. Hence, when the lock is installed in one configuration the key cylinder split pin box 362 will be received in one of the gaps, and when the lock is installed on the other configuration the split pin box 362 will be received in the other gap.
  • Retaining screw 361 is used for securing the key cylinder 36 in the body 30.
  • the snib link member 17 has a pair of small tabs 171 which extend through the aperture 301 in the body 30 when the lock is assembled.
  • the snib button 17a attaches to the link member 17 using the tabs 171 to become mounted as shown in Figure 2.
  • the snib button 17a can then be manipulated by hand from externally of the lock to operate the snib as described further below.
  • the snib link member 17 also has a pair of link arms 172. The operation of the link arms 172 will also be described further below.
  • the illustrated internal components of the lock include an operating plate 12, an upper parrot beak 14, a lower parrot beak 16, a drive member 18, a locking ring 19, a deadlock indicator arm 20, an anti-slam tongue 22, an anti-slam spring 23, a ball bearing 24 and a feedback spring 25.
  • Figures 4, 5 and 6 show these components assembled together.
  • Figure 4 shows the lock in the unlocked configuration.
  • the parrot beaks are rotated into their unlocking position, hi other words, the parrot beaks are rotated back into the cassette 10 (and therefore into the body 30, although the body is not shown in Figures 4-6).
  • the operating plate 12 is slid downwards into the first position as shown in Figure 4. Sliding the operating plate down into the first position rotates the beaks into the unlocking position because the operating plate 12 is provided with a pair of ridges 121 and 122 (also shown in Figure 1) that push down on the small knobs 141 and 161 on the upper and lower beaks respectively.
  • the knob 141 on upper beak 14 is located on the left-hand side of that beak's axis of rotation.

  • the operating plate 12 is slid upwards into the second position as shown in Figure 5. Sliding the operating plate up into the second position rotates the beaks into the locking position because the operating plate 12 is provided with a pair of ridges 123 and 124 that push up on the small knobs 161 and 141 respectively.
  • knob 141 is located on the left-hand side of the upper beak's axis of rotation and knob 161 is located on the right-hand side of the lower beak's axis of rotation, sliding the operating plate 12 upwards causes upper beak 14 to rotate clockwise and lower beak 16 to rotate counterclockwise into the locking position shown in Figure 5.
  • Figures 1, 4-6 also show that the lock incorporates a drive member 18 mounted in the centre of the lock mechanism, and secured in position by locking ring 19.
  • the drive member 18 is a circular rotating component with a protruding cam 181 extending from a portion of its perimeter and edge.
  • the operating plate 12 has a pair of ridges 126 and 127 which engage on either side of the cam 181 when the lock is assembled. Lower ridge 126 engages the cam 181 from below and upper ridge 127 engages the cam 181 from above. 29
  • the drive member 18 is coaxial with and connects to the barrel of key cylinder 36 (as described further below with reference to Figure 11), and so the drive member 18 can be rotated directly by rotating the key cylinder barrel.
  • the drive member 18 has been rotated clockwise. This causes the cam 181 to push downwardly on ridge 126, thereby forcing operating plate 12 down into the first position.
  • the position of the drive member 18 in Figure 4 is the lock opening position.
  • drive member 18 has been rotated counterclockwise causing cam 181 to push upwardly on ridge 127 forcing the operating plate 12 upwards into the second position.
  • the position of the drive member 18 in Figure 5 is the lock closing position.
  • FIG. 6 shows the lock in the deadlocked configuration.
  • the drive member 18 has been rotated counterclockwise past the lock closing position into the deadlocking position. It can be seen that, this further rotation of the drive member does not push the operating plate 12 any further up in the lock. However, it causes the cam 181 of the drive member 18 to be positioned directly above the drive member's axis of rotation. When the cam 181 reaches this position, the drive member 18 resists any attempt to unlock the lock otherwise than by the key cylinder. This is because any attempt to unlock the lock (except by the key cylinder) would need to slide the operating plate 12 downwards towards the first position to thereby unlock the parrot beaks.
  • any attempt to unlock the lock would cause the operating plate 12 to impart a downward vertical force on the cam 181.
  • the cam 181 is positioned directly above the drive member's axis of rotation, the line of action of the vertical force passes directly through the drive component's axis of rotation. Consequently, the force has no directional component that would cause the cam to rotate back towards the lock closing or lock opening positions.
  • the knob 161 on the lower beak 16 engages with ridge 129.
  • knob 141 on upper beak 14 engages with ridge 130 (only visible in Figure 1). Hence, any attempt to force the parrot beaks when the beaks are in the locking position is also resisted by the engagement of the knobs 141 and 161 with the ridges 130 and 129 respectively. Therefore, in order to be able to 30
  • the drive member 18 must first be rotated back to the lock closing position using the key cylinder 36. Once the cam 181 is rotated back into the lock closing position, any downward forces imparted on the operating plate 12 by the snib links 172 would in turn urge the cam 181 to move down in its arcing path around the drive component's axis of rotation, allowing the operating plate 12 to slide down into the first position to unlock the lock. This would then move the parrot beaks as normal.
  • the lock also incorporates a deadlock indicator arm 20.
  • the indicator arm 20 has a slightly flexible "wavy" portion 21 which engages with one of the mounting columns 101 in the cassette. This tends to push the indicator arm 20 downwards within the lock, biasing the deadlock indicator 20 to the retracted position shown in Figures 4 and 5.
  • the cam 181 of the drive member engages against the bottom of the indicator 20 pushing it upwards in the lock. This in turn causes the top of the indicator (or the tab mounted thereon-see Figures 7-10) to project out of the top of the lock providing a visual indication that the lock is deadlocked.
  • the opening in the lock furniture 33 through which the indicator projects is visible in Figure 2.

  • the anti-slam tongue 22 extends out from the lock as shown in Figure 4.
  • the small projection 221 on the side of the anti-slam tongue engages with the ridge 128 on the top portion of the operating plate 12.

  • the act of unlocking the lock will initially force the operating plate 12 down into the first position.
