Definitions

  • the present invention relates generally to mortise locks with multiple functions in which the functions can be selected or changed at installation thereof.
  • Mortise locks are known that provide a variety of functions, such as but not limited to, deadbolt operation, slam-lock operation, emergency operation and many others. Mortise locks are known that can be changed to operate with or without some of these functions. However, making these changes to the normal operation of the mortise lock has previously required partially or totally disassembling the mortise lock and rearranging or configuring the mortise lock components to achieve the desired mode of operation.
  • the present invention seeks to provide an improved and novel mortise lock in which the functions can easily be selected or changed at installation thereof, without disassembling the mortise lock, as is described more in detail hereinbelow.
  • the installer has four installation options: installing both the slam-lock operation and the emergency operation, just the slam-lock operation, just the emergency operation, or none of them.
  • a mortise lock including a case, a latch bolt, at least one locking bolt, a spindle hub mechanically linked to the latch bolt by a latch follower for retracting the latch bolt by rotation of the spindle hub, an activation receiver for slam-lock operation, wherein when a slam-lock activating member is installed in the activation receiver, the latch bolt is mechanically linked to the at least one locking bolt, such that retraction of the latch bolt into the case releases a catch to permit the at least one locking bolt to extend out of the case into a locking position, and wherein when the slam-lock activating member is not installed in the activation receiver, the latch bolt is not mechanically linked to the at least one locking bolt, such that retraction of the latch bolt into the case does not affect movement of the at least one locking bolt, and an activation receiver for emergency operation, wherein when an emergency activating member is installed in the activation receiver, the spindle hub is mechanically linked to the at
  • the catch extends from a pivoted bolt follower, and when the slam-lock activating member is installed in the activation receiver, inward movement of the latch bolt causes the slam-lock activating member to push against an end face of the pivoted bolt follower, so as to release the catch to permit the at least one locking bolt to extend out of the case into the locking position.
  • the at least one locking bolt is spring-loaded by a spring, and the catch, when in engagement with the at least one locking bolt, prevents the spring from pushing out the at least one locking bolt.
  • a spring-loaded lever that pivots about a pivot is connected to a locking bolt mover, and when the emergency activating member is installed in the activation receiver, turning the spindle hub causes the emergency activating member to push against the spring-loaded lever which moves the locking bolt mover to retract the at least one locking bolt into the case.
  • a spring-loaded deadbolt latch is arranged to protrude through the case, wherein an end of the deadbolt latch is arranged to push against a deadbolt follower inside the case and wherein the deadbolt follower engages a deadbolt stopper assembly inside the case, wherein when the deadbolt latch is pushed inwards into the case, the deadbolt latch pushes against the deadbolt follower, thereby geometrically locking the deadbolt stopper assembly into a position that blocks the at least one locking bolt and prevents forcing the at least one locking bolt from being moved inwards into the case, making the at least one locking bolt a deadbolt.
  • a slam-lock activating member and an emergency activating member are installed in the activation receivers for slam-lock operation and emergency operation, respectively (or just slam-lock operation, or just emergency operation or neither one of slam-lock and emergency operation).
  • the slam-lock activating member is constrained to travel in a straight slot formed in a cover plate.
  • the emergency activating member is constrained to travel in a curved slot formed in a cover plate.

  • Figs. 2A and 2B are simplified cutaway illustrations of the mortise lock of Fig. 1, respectively before and after activating deadbolt operation;
  • FIG. 3 is simplified pictorial cutaway illustration of the mortise lock of Fig. 1, showing activating members installed in activation receivers for both slam-lock operation and emergency operation of the mortise lock, in accordance with an embodiment of the present invention
  • FIG. 3 A is simplified pictorial cutaway illustration of the mortise lock of Fig. 1 , showing the slam-lock mode in operation;
  • Fig. 4 is simplified pictorial cutaway illustration of the mortise lock of Fig. 1, wherein no activating members have been installed in the activation receivers for emergency operation and slam-lock operation of the mortise lock, in accordance with an embodiment of the present invention
  • Fig. 5 is simplified pictorial cutaway illustration of the mortise lock of Fig. 1, wherein the activating member has been installed in the activation receiver for emergency operation and no activating member has been installed in the activation receiver for slam- lock operation of the mortise lock, in accordance with an embodiment of the present invention
  • Fig. 6 is simplified pictorial cutaway illustration of the mortise lock of Fig. 1, wherein the activating member has been installed in the activation receiver for slam-lock operation and no activating member has been installed in the activation receiver for emergency operation of the mortise lock, in accordance with an embodiment of the present invention.
  • Figs. 1 and 3 illustrate a mortise lock 10, constructed and operative in accordance with a non-limiting embodiment of the present invention.
  • Mortise lock 10 includes a case 12 that houses the internal parts of the lock.
  • a faceplate 14 is attached to case 12 and has apertures for various bolts to protrude therethrough, such as a latch bolt 16 and one or more locking bolts 18 (in the illustrated embodiment, there are two locking bolts 18 that move together on a common plate).
  • Case 12 has a cylinder aperture 20 for installing therein a cylinder lock 22 (shown in Fig. 3).
  • a spindle hub 24 is provided in case 12 for inserting therein a handle (not shown) for retracting latch bolt 16. This may be accomplished by means of a latch follower 26 (e.g., a tongue that extends outwards from spindle hub 24) which abuts against a tail stop 28 (Fig.
  • latch follower 26 pushes against tail stop 28 causing the latch bolt 16 to be retracted into case 12 (i.e., moved to the right in the sense of the drawing).
  • a return spring 30 (Fig. 3) causes latch bolt 16 to return to its position (leftwards) out of case 12.
  • cylinder lock 22 can also be used to retract latch bolt 16, by suitable linkage with tail stop 28 or with latch follower 26 or other mechanism.
  • Figs. 2A and 2B which illustrate activating the deadbolt operation.
  • a spring-loaded deadbolt latch 32 is arranged to protrude through faceplate 14.
  • the (rightmost) end 34 of deadbolt latch 32 is arranged to push against a slanted shoe 36 of a deadbolt follower 38.
  • the deadbolt follower 38 is constrained to move linearly up and down in the sense of the drawing by means of pins or screws 40 that move in slots 42.
  • An extension 44 of deadbolt follower 38 engages a deadbolt stopper assembly 46, which includes one or more plates 48 and a pin 50.
  • Fig. 2A shows the position when the door (not shown), in which mortise lock 10 is installed, is open, wherein deadbolt latch 32 protrudes through faceplate 14.
  • deadbolt latch 32 is pushed inwards into case 12 to the position shown in Fig. 2B. This causes the (rightmost) end 34 of deadbolt latch 32 to push against slanted shoe 36, thereby moving deadbolt follower 38 downwards. This in turn causes extension 44 to move plates 48 downwards as well. This causes pin 50 to geometrically lock into a recess 52 of deadbolt stopper assembly 46.
  • the deadbolt stopper assembly 46 is now geometrically locked in place and locking bolts 18 are now "dead”, that is, they cannot be forced into case 12 because their movement is blocked by deadbolt stopper assembly 46 (locking bolts 18 have become deadbolts).
  • mortise lock 10 can be adapted for operation in a slam-lock mode.
  • a slam- lock mode is a mode in which a locking bolt or the like is normally positioned in an extended position and is constrained, such as by a double-acting spring, so that when the door is closed or slammed shut, the locking bolt will initially retract upon closing engagement of the door and then immediately extend in order to lock and retain the door in closed engagement.
  • latch bolt 16 in the slam-lock mode latch bolt 16 is mechanically linked to locking bolts 18, such that when the door is closed or slammed shut, retraction of latch bolt 16 releases the retracted locking bolts 18 so that they immediately extend out of case 12 and lock and retain the door in closed engagement.
  • mortise lock 10 is provided with activation receivers 54 and 56 for slam-lock operation and emergency operation, respectively.
  • Fig. 3 illustrates mortise lock 10 with activating members 58 and 60, respectively installed in activation receivers 54 and 56 for both slam-lock operation and emergency operation of the mortise lock.
  • the activation receivers 54 and 56 may be sockets or holes or other suitable mounting provisions, and activating members 58 and 60 may be pins or screws (in which case the holes are tapped) that fit into the sockets or holes or other mounting provisions.
  • the activating members 58 and 60 may be easily installed when installing mortise lock 10 in the door and covered over with a cover plate 61 (Fig. 1), secured to case 12 with one or more fasteners 59.
  • the activating members 58 and 60 may be constrained to travel in a straight slot 57 and a curved slot 55, respectively, formed in cover plate 61.
  • activating member 58 e.g., a pin
  • activation receiver 54 e.g., a receiving hole
  • inward movement of latch bolt 16 causes activating member 58 to push against an end face 62 of a pivoted bolt follower 64 (i.e., latch bolt 16 is now mechanically linked to bolt follower 64 which is linked to the locking bolts 18).
  • latch bolt 16 is disconnected from bolt follower 64, and inward movement of latch bolt 16 does not cause any movement of pivoted bolt follower 64.
  • mortise lock 10 can be adapted for operation in an emergency mode.
  • an emergency mode is a mode in which a locking bolt or the like can be retracted from one side of the door (usually the inside of the door) even if the door is nominally locked with the cylinder lock (i.e., overriding the cylinder lock).
  • spindle hub 24 is mechanically linked to locking bolts 18, such that turning spindle hub 24 with the handle retracts the locking bolts 18 and overrides cylinder lock 22.
  • activating member 60 (e.g., a pin) is installed in activation receiver 56 (e.g., a receiving hole).
  • activation receiver 56 e.g., a receiving hole.
  • activating member 60 is installed in activation receiver 56
  • turning spindle hub 24 with the handle causes activating member 60 to push against a spring-loaded lever 68 that pivots about a pivot 70 (Fig. 3 shows lever 68 pushed to the right).
  • An end 72 (leftmost end) of lever 68 is connected (e.g., pinned) to a locking bolt mover 74 (72 and 74 are seen in Figs. 1 and 2B).
  • Locking bolt mover 74 when moved to the right, can override the cylinder lock 22 and retract the locking bolts 18.
  • spindle hub 24 is mechanically linked to locking bolts 18 via lever 68.
  • activating member 60 is not installed in activation receiver 56, spindle hub 24 is disconnected from lever 68, and turning spindle hub 24 does not cause any movement of pivoted lever 68.
  • the installer has the option of installing both the slam-lock operation and the emergency operation by installing both activating members 58 and 60, as in Figs. 1-3.
  • Fig. 4 illustrates another option in which no activating members have been installed in the activation receivers, so there is no emergency operation and no slam-lock operation.
  • FIG. 5 illustrates another option in which the activating member 60 has been installed in the activation receiver 56 for emergency operation and no activating member has been installed in the activation receiver 54 and there is no slam-lock operation.
  • FIG. 6 illustrates another option in which the activating member 58 has been installed in the activation receiver 54 for slam-lock operation and no activating member has been installed in the activation receiver 56 and there is no emergency operation.
