Preferably, shuttle 47 is biased towards primary importance by shuttle biasing device 48, shown in the ghost line in Fig. 3.This shuttle biasing device acts between shuttle 47 and framework 23, thus promoting shuttle 47 to move towards the head 22 of latch bolt assembly 21.Shuttle 47 can move to the second position by the rotation of any one in cam 19 or hub 33,34, and which will be described below.Preferably, the power that shuttle biasing device applies to shuttle 47 is less than the power applied to latch bolt 21 by latch bolt biasing device 24.This allows shuttle 47 to move relative to latch bolt 21, thus adjusting the position of locking key 46 before latch bolt 21 itself is mobile.

Latch bolt assembly 21, locking mechanism 29 and release device 45 is illustrated with exploded view referring now to Figure 11, Figure 11.This figure exposes the framework 23 of latch bolt assembly 21 and is formed by two parts, and both parts is nested in each other to prevent the relative motion on the moving direction of latch bolt assembly when assembling.Locking mechanism 29 is also nested on framework 23, thus the arm 91 of locking key 46 is arranged in the groove 92 of framework 23.The lower limb 93 of locking key 46 is against the sidewall 94 of framework 23, thus lower limb 93 and sidewall 94 are in slip over each other when locking key 46 is moved between blocking position and non-blocking orientation.Locking mechanism 29 includes the locking key biasing device 90 compressed shown in form of springs, and locking key biasing device 90 acts between framework 23 and locking key 46 to promote locking key 46 to take blocking position.The motion of the locking key 46 under the effect of biasing device 90 is subject to the restriction of the protuberance 95 of the framework 23 of the shoulder 96 against locking key 46 when it arrives blocking position.When the motion of the shuttle 47 under the effect at biasing device 48 is subject to the restriction against the projection 97 in the back wall 98 of the framework 23 of the sidewall 99 of shuttle 47, shuttle 47 arrives primary importance.

Referring still to Figure 11, it should be noted that the head 22 of latch bolt assembly 21 can and rotate from the position shown in Fig. 2 relative to framework 23.Head 22 relative to the ability that framework rotates, mortice lock can be opened for right side or left side is opened and assembled.

The mode of mortice lock operation be will now be described or more specifically how latch bolt assembly 21 is retracted.With reference first to Fig. 4, Fig. 5 and Fig. 6, the figures illustrate and make latch bolt assembly 21 retract by the operation of cylinder lock 5.Such as what be contemplated to when door 9 (referring to Fig. 1) is positioned at closed position, Fig. 4 illustrates the latch bolt assembly 21 being positioned at extended position and the auxiliary bolt 26 being positioned at retracted position.Cam 19 causes shuttle 47 to overcome the thrust of shuttle biasing device 48 to move to the second position shown in Fig. 5 from the primary importance shown in Fig. 4 from the position shown in Fig. 4 to the rotation of the position shown in Fig. 5.Shuttle 47 includes ramped surfaces 50 (see also Figure 11), and ramped surfaces 50 engages the complementary ramps surface 51 (see also Figure 11) formed on the lower limb 93 of locking key 46.The shuttle 47 motion from primary importance to the second position causes ramped surfaces 50,51 in slip over each other, thus locking key 46 is returned to the non-blocking orientation shown in Fig. 5 from the blocking position shown in Fig. 4.This motion of locking key 46 also overcomes the thrust of locking key biasing device 90, and locking key 46 is positioned at below retainer 49, thus allowing latch bolt assembly 21 to move from extended position.

It should be noted that latch bolt assembly 21 still not yet moves from its extended position from Fig. 5.Fig. 5 illustrates that shuttle 47 is against framework 23 so that further rotating of cam 19 causes latch bolt assembly 21 to be directly retracted into retracted position from extended position, as shown in Figure 6.This makes the head 22 of latch bolt assembly be fully located in housing 7, to allow to open door 9.

Referring now to Fig. 7, Fig. 8 and Fig. 9, the figures illustrate the operation by actuator 23 and latch bolt assembly 21 is retracted.Shuttle 47 can move to the second position by the rotation of any one in interior hub 33 or outer hub 34 (being blocked in the figure 7) from primary importance.Fig. 7 again illustrates the locking key 46 being positioned at blocking position and the shuttle 47 being positioned at primary importance.Interior hub 33 rotates to the position shown in Fig. 8 from the position shown in Fig. 7, to cause shuttle 47 to overcome the effect of shuttle biasing device 48 (referring to Fig. 9) to move to the second position from primary importance.Ramped surfaces 50 on shuttle 47 engages from the blocking position shown in Fig. 7, locking key 46 is pulled to the non-blocking orientation shown in Fig. 8 with the ramped surfaces 51 in locking key 46.This makes locking key 46 be positioned at below retainer 49, so that latch bolt assembly 21 freely moves from extended position.Will be consequently realised that from Fig. 9, the free end 61 of interior hub 33 has engaged the inner surface 52 of shuttle 47, to be pressed against on the rear wall 53 of framework 23 by shuttle 47.Further rotating of interior hub 33 causes latch bolt assembly 21 to move to the retracted position shown in Figure 10.This makes the head 22 of latch bolt assembly be fully located in housing 7 to allow to open door 9.

It should be appreciated that when cam 19 or hub 33 rotate in the opposite direction thus when being returned to the position shown in Fig. 2, latch bolt biasing device 24 promotes latch bolt 21 to return to the extended position shown in Fig. 2.Additionally, shuttle biasing device 48 also will promote shuttle 47 to take the primary importance shown in Fig. 2.But, when auxiliary bolt 26 is positioned at extended position, the arm 91 of locking key 46 will engage body 28, thus preventing locking key from taking blocking position.

When door 9 is positioned at closed position, it is usually desirable to be only just latch bolt assembly 21 can be retracted by cylinder lock 65 in or beyond user operation or inner or outer handle 12,15.More specifically, generally it would not be desirable that operate mortice lock assembly 4 so that latch bolt assembly 21 is moved to retracted position by being applied to the head 22 of latch bolt assembly 21 by pressure against the ends.Locking mechanism 29 according to the present invention utilizes locking key 46 to prevent this unauthorized movement of latch bolt assembly 21.The preferred form of the locking key 46 of diagram is placed on framework 23, and can move between blocking position and non-blocking orientation on the direction orthogonal with the latch bolt assembly 21 motion between extended position and retracted position.This motion of locking key 46 occurred before latch bolt assembly 21 starts to retract.
