Detailed description of the invention

Illustrating the embodiment of lockset 1 referring now to Fig. 1, Fig. 1, put it briefly, lockset 1 includes mortice lock assembly 2, interior door furniture 2 and outer door furniture 4. Mortice lock assembly 4 includes housing 5, and housing 5 is arranged in formation in use in the mortise cavity 6 of the lateral edges of door 7. The inner side of interior door furniture 3 and door 7 is positioned adjacent to, and the outside of outer door furniture 4 and door 7 is positioned adjacent to.

Interior door furniture 3 shown in Fig. 1 includes escutcheon 8 in rectangle, interior lever handle 99 and inner cylinder lock set 9, and inner cylinder lock set 9 is directed at the opening 10 in interior escutcheon 8 in use. Outer door furniture includes outer rectangle escutcheon 11, outer lever handle 12, outer cylinder lock set 13. Equally, when lockset in use, outer cylinder lock set 13 is arranged in the opening 14 of outer escutcheon 11. Interior lever handle 99 and outer lever handle 12 all can rotate around actuator axis XX, thus rotating inner axis of heart 16 and outer axle 16 respectively.

The actuator 17 of inner axis of heart 15 and outer axle 16 and mortice lock assembly 2 interacts, and only a part for actuator 17 is visible in FIG. Actuator 17 will be more fully described with reference to diagram after a while. Should be realized that, it is illustrated that inner handle 99 and outdoor handle 12 be only the preferred form being suitable for rotating the component closed that can catch of inner axis of heart 15 and outer axle 16. Inner handle 99 and outdoor handle 12 could alternatively be turning knob etc.

Inner cylinder lock set 9 and outer cylinder lock set 13 all include sleeve 19 and lock core 20 (only internal cylinder 20 is visible in FIG), and by inserting suitable key (not shown), lock core 20 can rotate in sleeve 19. Cam 21 (only the cam on outer cylinder lock 19 is visible in FIG) is attached to the rear portion of lock core 20, thus rotating together with lock core 20. Cam 21 by by with reference to illustrate after a while be more fully described in the way of interact with the features of mortice lock assembly 2. It should be appreciated, however, that according to which features in mortice lock assembly interacting, the shape of cam 21 can be different from the shape shown in Fig. 1. Although additionally, Fig. 1 suggested pellet cylinder lock assembly, but the present invention can include any type of cylinder lock assembly.

Housing shown in Fig. 1 is included pedestal 22 and is attached to the cover 23 of pedestal 22 by screw fastener 24. Antetheca 25 is attached to pedestal 22 by screw fastener 18 (referring to Figure 15). Panel 26 is attached to pedestal 22 also by screw fastener 27 through antetheca 25. Panel 26 is intended to pull down from housing 5 by being removed by screw fastener 27 when door 7 is in open mode, in order to adjust operator scheme, will be more fully described this operator scheme with reference to diagram after a while.

Illustrating mortice lock assembly referring now to Fig. 2, Fig. 2, wherein cover 23 is pulled down to expose the inner member of mortice lock 2 from pedestal 22. While figure 2 show that be referred to as the mortice lock assembly of standard gate back gauge, it will be appreciated that present invention can also apply to hatch back gauge and long door back gauge.

The present invention includes taking any type of latch bolt assembly 28. Fig. 2 illustrates the latch bolt assembly 28 with the beveled head 29 being attached to body 30. The shape of head 29 can be different from the inclined plane shape shown in figure, for instance, head 29 can alternatively have fillet (bullnose) shape. Latch bolt assembly 28 is shown at extended position, and at this extended position, head 29 stretches out through the opening in antetheca 25. Act between latch bolt assembly 28 and butting section 32 compressing the latch bolt biasing device 31 shown in this preferred form of spring. The butting section 32 of diagram is in position relative to housing 7, but, it can alternatively form with housing 7. Latch bolt biasing device 31 acts on latch bolt assembly 28 to be biased towards extended position as shown in Figure 2.

Fig. 2 also show auxiliary bolt 34, and auxiliary bolt 34 has the wedge-shaped head 33 extended through another opening in antetheca 25. Auxiliary bolt also includes body 35, and body 35 is positioned at after antetheca 25 in housing 7, thus interacting with the locking mechanism 36 on the body 30 being positioned at latch bolt assembly 28. Again act between auxiliary bolt 34 and butting section 88 compressing the auxiliary bolt biasing device 37 shown in this preferred form of spring. Butting section 88 is shown as forming with pedestal. Attaching latch is biased towards extended position as shown in Figure 2 by auxiliary pin biasing device 37.

Locking mechanism 36 includes deadlocking member 38, deadlocking member 38 must be oriented to avoid with and the retainer 39 of pedestal 22 association contact, in order to latch bolt assembly 28 can be moved from extended position. While attaching latch 34 keeps being in extended position (when being such as positioned at open position when door 7), deadlocking member 38 will be avoided engaging with retainer 39. But, when when auxiliary bolt 34 is retracted and situation Xiamen 7 that latch bolt 28 stretches out is closed, deadlocking member 38 will be directed at retainer 39. When latch bolt assembly 28 is retracted by actuator 17, shuttle 40 and deadlocking member 38 interact, so that deadlocking member 38 moves and is not directed at retainer 39. Think: when deadlocking member 38 is aligned and engages with retainer 39, locking mechanism 36 is in active state; When deadlocking member 38 is moved and avoids engaging with retainer 39, locking mechanism 36 is in non-applied state.

Form the actuator 17 according to a part for the mortice lock assembly 2 of the present invention to be operable to from extended position, latch bolt assembly 28 is moved to retracted position (referring to Fig. 4). This actuator can take to realize any form of this function, and Fig. 2 illustrate only a preferred form of actuator 17. The actuator 17 of diagram includes interior hub 41 and the outer hub 42 (being blocked) that can rotate independently around actuator axis XX (referring to Fig. 1). Each including in interior hub 41 and outer hub 42 is respectively used to receive the axle recess 43 (in only, the axle recess of hub 41 is visible in fig. 2) of inner axis of heart 15 and outer axle 16. Each include arm 44, the free end of arm 44 and latch bolt assembly 28 in interior hub 41 and outer hub 42 interact. More specifically, the free end of arm 44 interacts with the shuttle 40 of detent mechanism 36. Interior hub 41 or outer hub 42 rotate shuttle 46 is shifted to the inwall 45 of housing 5, and locking mechanism is adjusted to non-applied state by this rotation, thus allowing latch bolt assembly 28 to move towards retracted position. Actuator 17 also includes actuator biasing device 46, and actuator biasing device 46 acts on the protuberance 47 of interior hub 41 and outer hub 42. This promotes interior hub 41 and outer hub 42 to resist described rotation.

Mortice lock assembly 2 according to the present invention includes causing the inoperable locking device 48 of actuator 17 when being in active state. Locking device 48 can take any form to realize this function, and the invention is not restricted to locking device as depicted. The locking device 48 of diagram includes slip locking key 49, interior pawl 50 and outer pawl (this outer pawl is invisible in the drawings). Fig. 2 illustrates the locking device 48 being in non-applied state, and in this non-applied state, actuator 17 can operate and make latch bolt 28 move from extended position. When locking device 48 is in non-applied state, interior pawl 50 and/or outer pawl separate with actuator. To be more fully described from non-applied state adjusting and locking mechanism 48 by referring to diagram after a while.

Mortice lock assembly 2 according to the present invention also includes selector installation 51, and selector installation 51 can be adjusted selecting operator scheme. Selector installation 51 can take any form, will be more fully described selector installation 51 with reference to diagram after a while. But, Fig. 2 illustrates the far-end 52 of the selector component 53 of the part defining selector installation 51. Additionally, Fig. 2 illustrates the selector installation 51 being under normal manipulation mode, at this normal manipulation mode, when latch bolt moves to retracted position, selector installation 51 is avoided interacting with locking device 48.

By with reference to Fig. 3, Fig. 4 and Fig. 5 describe mode that mortice lock 2 operates or more specifically latch bolt assembly 28 how to retract. Illustrate the latch bolt assembly 28 being positioned at extended position with reference first to Fig. 3, Fig. 3, wherein auxiliary bolt 34 also is located at extended position. Locking mechanism 36 is maintained at non-applied state by this, thus allowing latch bolt assembly 28 to retract from extended position. It is further noted that locking device 48 is in non-applied state from Fig. 3, wherein slip locking key 49 is positioned at cocked position relative to pawl 50. Pawl 50 is shown under the impact of pawl biasing device 54 and takes non-locking state, pawl biasing device 54 to include compression spring 55 and the follower 56 acted also on pawl 50. When such as door 7 (referring to Fig. 1) is positioned at open position, the mortice lock assembly 2 shown in Fig. 3 can take this structure.

Door 7 (referring to Fig. 1) move to closed position will cause mortice lock assembly at least temporarily to take structure as shown in Figure 4. Fig. 4 illustrates latch bolt assembly 28 and auxiliary bolt 34, and both of which moves to retracted position. It is further noted that the far-end 52 of selector installation 53 has been moved into closer to slip locking key 49 from Fig. 4, without the position from the cocked position adjustment slip locking key 49 shown in Fig. 3.

Fig. 5 illustrates mortice lock assembly, and wherein locking device 48 is adjusted to active position. Cam 21 has been rotated into engaging slide locking key 49 and has made slip locking key 49 move down towards pawl 50, and this causes pawl 50 to rotate around pawl axle 57, when pawl 50 takes this position, it is prevented that hub 41 rotates. It should be understood that slip locking key 49 can cause outer pawl (not shown) to rotate in the way of being similar to interior pawl 50, thus preventing outer hub 42 from rotating. Will refer only to the interaction between slip locking key 49 and interior pawl 50 below to describe mortice lock, however, it is to be appreciated that this interaction is readily adaptable for use in outer pawl. It is further noted that locking device 48 can be retained in active state from Fig. 5, latch bolt 28 is positioned at retracted position simultaneously. This realizes when selector installation 51 operates in a normal operating mode, and at this normal manipulation mode, the far-end 52 of selector component 53 does not interact with the slip locking key 48 of locking device.

Describe the mortice lock assembly 2 mode of operation under delay pattern (holdbackmode) now with reference to Fig. 6, Fig. 7 and Fig. 8 or more specifically how latch bolt assembly 28 be maintained at retracted position. Fig. 6 illustrates the latch bolt assembly 48 being positioned at extended position, and wherein selector installation is taked to be detained operator scheme. When selector installation 51 is in this operator scheme, the far-end 52 of selector component 53 is oriented such that and forms recess 58 in far-end 52 towards upward direction. User is then generally by using thumb to apply pressure against the ends to the head 29 of latch bolt assembly 28, so that latch bolt assembly moves to retracted position, as shown in Figure 7. This makes the recess 58 at far-end 52 place of selector component 53 be directed at the lug 50 of slip locking key 49. Fig. 8 illustrates that the rotation of cam 21 makes slip locking key 49 move down, so that lug 59 is positioned at recess 58. Latch bolt assembly 28 is maintained in retracted position by this. Also should note from FIG. 8 that, pawl 50 is rotated to latched position, in this latched position, it is prevented that actuator 17 operates. This will make interior lever handle 99 and outer lever handle 12 (referring to Fig. 1) be in rigid state, and allows door 7 to move to open position, without rotating any one lever handle 9,12.

Preferably, when selector installation 51 is in delay operator scheme and locking device 48 already at active state, it is prevented that lug 59 is unexpected to be positioned in recess 59. Such as, when locking device 48 be in active state and door 7 from open position move to closed position thus latch bolt 28 is retracted time, it may occur that this situation. Below with reference to Fig. 9 and Figure 10, this is described.

Fig. 9 illustrates the latch bolt 28 being positioned at extended position and the locking device 48 being in active state, and wherein selector installation 51 is still within being detained operator scheme. This makes the far-end 52 of selector component 53 be directed at the lug 59 in slip locking key 49. Illustrate the latch bolt 28 moving to retracted position referring now to Figure 10, Figure 10, at this retracted position, the far-end 52 of selector installation 53 engagement lug 59 also makes lug 59 deflect. This prevent lug 59 to be positioned in the recess 58 in the far-end 52 of selector component 53, this prevent latch bolt 28 and be maintained at retracted position. Preferably, lug 59 is biased to the orientation shown in Fig. 8. This is realized by counter-jib 60, and counter-jib 60 promotes lug to rotate in the clockwise direction, until lug engages with the wall 87 formed in slip locking key 49. But, this counter-jib 60 could alternatively be torque spring etc.

Now with reference to accompanying drawing 11, Figure 12 and Figure 13, the mode of operation of mortice lock 2 when selector installation 51 is under anti-lock pattern is described. Figure 11 illustrates slip locking key 49 faced by the ramped surfaces 51 that the far-end 52 of selector component 53 is positioned such that on this far-end. Figure 11 also show cam 21 and is rotated into driving slip locking key 49 downwards so that locking device 48 is in active state. This causes pawl 50 to rotate around pawl axle 57 thus preventing actuator 17 from operating. Latch bolt 28 is shown at extended position.

Illustrate that latch bolt assembly 28 is partially retracted referring now to Figure 12, Figure 12, thus the ramped surfaces 61 engaging slide locking key 49 on the far-end 52 of selector component 53. The retraction of the latch bolt 28 shown in Figure 12 causes owing to door 7 moves to closed position, rather than because the rotation of hub 41 causes. Figure 13 illustrates that latch bolt assembly 28 is retracted further, thus locking key 49 of sliding is slided in the ramped surfaces 61 of the far-end 52 of selector component 53. This causes slip locking key 49 to be risen, thus non-applied state taked by locking device 48. This allows pawl 50 to rotate to non-locked position under the impact of pawl biasing device 54, thus allowing actuator 17 to operate.

Alternatively, the retraction of latch bolt assembly 28 can also cause due to the rotation of interior hub 41 or outer hub 42. Interior pawl 50 can rotate in the clockwise direction from the position shown in Figure 13, to take rest position (outer pawl can also take rest position). When interior (or outer) pawl 50 is positioned at rest position, this interior (or outer) pawl can not interact with slip locking key 49. Thus, when interior pawl 50 is in dead status, outer pawl can take latched position, thus preventing outer hub 42 from rotating, and interior hub 41 still rotates freely. If selector installation is under anti-lock pattern, then in, the rotation of hub 41 will cause latch bolt assembly 28 seat meeting, and adjust the state of locking device 48 to non-applied state.

It is further noted that the spheroid locking key 62 associated with locking key 49 of sliding is arranged in formation above the spine 63 of rear wall 45 from Figure 13, thus slip locking key 49 is maintained at cocked position. Even if after latch bolt assembly 28 returns to extended position under the impact of latch bolt biasing device 31, this will also ensure that slip locking key 49 is maintained at cocked position. On the contrary, by making spheroid locking key 62 be positioned at below spine 63, spheroid locking key 62 promotes slip locking key 49 to be positioned at the down position described in Figure 12. It should be appreciated that by making selector installation be under anti-lock pattern, if door 7 is moved to closed position from open position, then this is prevented from locking device 48 and is retained in active state.

Selector installation 51 according to the present invention can take on any appropriate form, as long as this selector installation can at least be detained between pattern and anti-lock pattern and adjust operator scheme. The preferred form of selector installation is shown in Figure 14 relevant to latch bolt assembly 28. The body 30 of latch bolt 30 is shown at its dismounting form, to illustrate that body 30 is formed by frame section 64 and insertion section 65. Body 30 is formed by two parts, consequently facilitating the assembling of latch bolt 28 and feature associated there. This framework includes antetheca 66 and rear wall 67, has two openings 68,69 in antetheca 66. Larger open 68 in the two opening receives the short axle 70 (being blocked by head 29) being associated with head 29, and short axle 70 allows head 29 to rotate relative to framework 64 in that larger open 68. Smaller opening 69 in antetheca 66 is directed at the similar little opening 70 in rear wall 67, and both receives the axle portion 71 of selector component 53. When mortice lock assembly 2 is assembled, the near-end 72 of selector component 53 is positioned adjacent to the antetheca 66 of framework 64, and the rear wall 67 of the far-end 52 of selector component 53 and framework 64 is positioned adjacent to. Marginal texture 73 and the cervical region 74 of axle 71 on insertion section 65 are positioned adjacent to, thus when insertion section 65 is placed on framework 64, selector component 53 is caught by the body of latch bolt assembly.

Preferably, selector installation 51 forbids that selector component 53 rotates around selector axis 22 except being configured in time adjusting operator scheme at near-end 72 place. Selector installation 51 can construct to realize this function in any appropriate form, Figure 14 illustrate the axle 71 of selector component 53 include spheroid recess 75 with and the spheroid locking key 76 that is associated of insertion section 65 interact. The spheroid 77 of spheroid locking key 76 is biased by compression spring 78, thus once selector component 53 has been rotated to tram, (positively) is placed in the spheroid recess 75 on the axle of selector component 53 just in form-fit manner. Spheroid locking key 76 device prevents the unexpected possibility rotated of selector component 53, and adds selector component 53 relative to the pinpoint possibility of latch bolt 28. The axle 71 of selector component 53 includes three spheroid recesses 75, and these three spheroid recess 75 is corresponding with the selector component 53 being positioned at delay pattern, anti-lock pattern and normal mode respectively. Additionally, cervical region 74 covers the 3/4 of the circumference of axle 71, and interact with marginal texture 73, to limit the rotation of axle 71, to take a pattern in these three pattern.

Figure 14 also show the shuttle 40 on the framework 64 being respectively positioned on latch bolt assembly 28 and locking key component 38. Act on the shuttle biasing device 78 between the rear wall 67 of framework 64 and shuttle 40 and shuttle 40 is pushed to the antetheca 66 of framework 64.
