Embodiment Construction

[0023] now refer to figure 1 and image 3 , shows a mortise lock 10 constructed and operative in accordance with a non-limiting embodiment of the present invention.

[0024] Mortise lock 10 includes a housing 12 that houses the internal components of the lock. A faceplate 14 is attached to the housing 12 and has features for, for example, a deadbolt 16 and one or more deadbolts 18 (in the embodiment shown, there are two deadbolts 18 , the two deadbolts 18 A hole through which various pins protrude on a common board that move together. Housing 12 has cylinder hole 20, so that cylinder lock 22 ( image 3 shown in ) is installed in the cylindrical hole 20. Disposed within the housing 12 is a hub 24 in which a handle (not shown) for retracting the deadbolt 16 is mounted. This can be accomplished by a latch follower 26 (e.g., a tongue extending outwardly from the hub 24) that abuts a tail stop 28 on the stem of the deadbolt 16 ( image 3 ). As the hub 24 is rotated clockwise...

Abstract

A mortise lock (10) including a case (12), a latch bolt (16), at least one locking bolt (18), and a spindle hub (24) mechanically linked to the latch bolt (16) by a latch follower (26) for retracting the latch bolt (16) by rotation of the spindle hub (24), characterised by an activation receiver (54) for slam-lock operation and an activation receiver (56) for emergency operation.

Description

technical field [0001] The present invention generally relates to mortise locks having multiple functions, wherein the functions can be selected or changed when the mortise lock is installed. Background technique [0002] Mortise locks are known to provide various functions such as, but not limited to, deadbolt operation, slam latch operation, panic operation, and 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 previously required partial or total disassembly of the mortise lock and resetting or reconfiguring the mortise lock components to achieve the desired mode of operation. [0003] While these changes can be reliably made at the factory by specially trained personnel, the task of dismantling the mortise lock is a rather time consuming process. Also, dismantling the mortise lock provides an opportunity to destroy components. Additionally, p...
