Description

Technical Field

[0001] The utility model relates to a door lock system, in particular to an improved door lock component. Background Art

[0002] Common door lock assemblies generally include a deadbolt and a latch, both of which are enclosed within the assembly. The latch and deadbolt mechanism typically occupy the majority of the space within the lock assembly. The latch is necessary to lock the door, while the deadbolt facilitates securing the door in the closed position. However, there are some situations where the design and construction of the lock assembly are subject to constraints, which may affect the space available for fitting the deadbolt and latch mechanism.

[0003] This constraint is often caused by the need to accommodate a variety of door styles. In some cases, a smaller lock assembly is required to maintain the structural integrity and aesthetics of an older building. This is because older buildings are generally not suitable for large lock assemblies because they may have structural elements that are prone to damage or weakened in strength. In other cases, modern architectural styles may require smaller lock assemblies to achieve a minimalist look; for example, frameless glass doors in modern buildings require compact locks to maintain their streamlined appearance.

[0004] Another factor that contributes to space constraints is the incorporation of additional technology into a standard lock assembly size, leaving less space for the latch and deadbolt mechanism. For example, technologies such as biometric scanners, wireless connectivity modules, tamper detection mechanisms, and alarms may be incorporated into the lock assembly, requiring the size of mechanical components such as the latch and deadbolt to be reduced.

[0005] In situations where the lock assembly is space constrained, fitting the latch and deadbolt into the assembly becomes challenging. One way to address this challenge is to use a latch-only door lock assembly. However, this approach often leads to usability issues because the lack of a deadbolt means the door must be latched every time to keep it closed.

[0006] Another common solution involves using a lock assembly equipped with only a deadbolt, where the lock assembly of the separate deadbolt is mounted externally. However, this approach may detract from the aesthetics of the door. It may also cause security issues as an externally attached lock assembly is generally easier to tamper with than a lock assembly that is incorporated into the door. Utility Model Content

[0007] Technical issues:

[0008] To address the challenges of combining a latch and lock within a dimensionally constrained space within a door lock assembly - including challenges that compromise security, hinder usability, and compromise the structural integrity or aesthetics of the door - the present invention introduces a door lock assembly that utilizes a deadbolt equipped with a locking mechanism that effectively enables the deadbolt to function as a latch.

[0009] Technical Solutions

[0010] The utility model provides a door lock component with a telescopic lock tongue. The telescopic lock tongue plays the role of a standard door latch and also plays the role of a locking latch.

[0011] In its standby state, the bolt extends from the door and can be mechanically retracted by turning a handle, a lever or a similar drive unit, thereby functioning as a normal door latch. The bolt can be locked when extended from the door, thereby preventing it from being retracted into the door, so that it can function as a latch to secure the door in a closed state. Alternatively, the bolt can be locked when retracted, thereby securing the door in an open state.

[0012] The mechanism that controls the locking of the deadbolt is enclosed in the lock assembly. Engaging the mechanism locks the deadbolt and immobilizes it, thereby preventing the deadbolt from moving. Conversely, disengaging the mechanism unlocks the deadbolt, allowing it to move freely.

[0013] The deadbolt is connected to a deadbolt actuating mechanism that is operated by a knob, handle, lever, or similar drive unit. When the deadbolt is locked, the drive unit also locks, resisting any applied force and preventing it from moving. This deviates from the standard user interaction pattern, where the drive unit remains movable even when the lock is engaged; because in standard assemblies, the deadbolt and latch are separate components. In addition, this resistance may cause increased wear on the deadbolt locking mechanism.

[0014] To address possible wear, a more robust mechanism or incorporating a force dampener may be considered. However, usability and wear issues may be addressed by decoupling the deadbolt actuation mechanism from the deadbolt when the deadbolt is locked. This allows the handle, knob, or other drive unit to operate freely, ensures consistent user interaction, and eliminates any pressure or stress on the deadbolt locking mechanism.

[0015] According to the utility model, a door lock assembly is provided, comprising a door lock body, and:

[0016] a lock tongue movable between an extended position and a retracted position relative to the door lock body;

[0017] a bolt actuating mechanism for driving the bolt to move between an extended position and a retracted position; and

[0018] The bolt locking mechanism can move between a locking position and an unlocking position. In the locking position, the bolt is locked in an extended position or a retracted position. In the unlocking position, the movement of the bolt is not restricted.

[0019] Preferably, the lock tongue and the lock tongue locking mechanism are respectively arranged on axes parallel to each other, and the lock tongue or the lock tongue axis and the lock tongue locking mechanism axis also include lock tongue locking fittings, respectively. In the locked position, the lock tongue locking fittings engage to lock the lock tongue in place, and in the unlocked position, the lock tongue locking fittings separate to unlock the lock of the lock tongue.

[0020] Preferably, the mutually cooperating parts of the deadbolt and the deadbolt locking mechanism are protrusions and slots, locking rods and plates respectively arranged on the deadbolt and the shaft of the deadbolt locking mechanism, or racks and holes, disengagement arms and holes respectively arranged on the shaft of the deadbolt locking mechanism and on the deadbolt.

[0021] Preferably, when the bolt locking mechanism is in the locked position, the bolt actuating mechanism is also locked so that it cannot move.

[0022] Preferably, the lock tongue further comprises a lock tongue actuating mechanism locking piece fixed thereon, wherein the lock tongue actuating mechanism locking piece engages with the lock tongue actuating mechanism when the lock tongue is locked in place to prevent the lock tongue actuating mechanism from operating.

[0023] Preferably, the lock bolt comprises a lock bolt shaft, and the lock bolt actuating mechanism locking element is a solid plate fixed on the lock bolt shaft, and when the lock bolt is locked in place, the solid plate is also locked in place, thereby preventing the lock bolt actuating mechanism from actuating the lock bolt.

[0024] Preferably, when the bolt locking mechanism is in the locking position, the bolt actuating mechanism is simultaneously disengaged from the bolt through the bolt disengaging mechanism, so that the movement of the bolt actuating mechanism cannot drive the bolt to move.

[0025] Preferably, the lock tongue comprises a lock tongue shaft, and the lock tongue disengaging mechanism is a solid plate with a cutout portion fixed to the lock tongue shaft, when the lock tongue is locked in place, the cutout portion of the solid plate with the cutout portion is aligned with the lock tongue actuating mechanism, and when the lock tongue is unlocked, the solid portion of the solid plate with the cutout portion is aligned with the lock tongue actuating mechanism.

[0026] Preferably, the door lock further comprises a lock bolt which is installed in the door lock body and is different from the lock tongue. The lock bolt can move between a locking position and an unlocking position relative to the door lock body.

[0027] Preferably, the bolt actuating mechanism can be driven electrically or by a handle or a knob, and the bolt locking mechanism can be driven electrically or by a unlocking tool.

[0028] benefit

[0029] Combining the functions of the latch and the deadbolt into the deadbolt optimizes space within the door assembly, resulting in a more compact door lock assembly. This allows for a range of door designs and architectural styles, from traditional to contemporary, to be accommodated without compromising its structural integrity or aesthetic appeal.

[0030] Additionally, the compact assembly provides increased tamper resistance compared to external latch systems, which are often required for mortise locks with space constrained spaces in doors. The compact design enables the assembly to fit into space constrained mortise locks, making the door lock less susceptible to unauthorized interference.

[0031] Additionally, using a compact assembly with a lockable deadbolt, rather than a lock that only uses a deadbolt, retains the functionality of locking the door in a closed position. By being able to lock the deadbolt, the door can still be opened by using an actuation unit such as a handle, knob, or lever, thereby maintaining a consistent user interaction.

[0032] Furthermore, the space saved by combining the door latch and deadbolt functions into the deadbolt allows additional features to be incorporated into the assembly. These additional features include, but are not limited to: door switch sensors, tamper detectors, alarms, authentication modules, and electronic circuits.

[0033] Finally, the deadbolt's dual functionality as both a latch and a bolt reduces the number of parts required to operate the door lock assembly, resulting in a more efficient manufacturing process. The reduction in parts not only benefits production and assembly, but also contributes to the overall reliability and maintainability of the door lock system. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] DETAILED DESCRIPTION

[0046] Figure 1 ：

[0047] Figure 1 Four groups of door lock assemblies A, B, C, D are shown, each group including two door lock assemblies, namely MORT-100, MORT-200, MORT-300, MORT-400, MORT-500, MORT-600, MORT700, MORT-800, for the purpose of describing: door lock assemblies of different sizes, different structures of latches 5 and tongues 2 on these assemblies, different ports 6, 8 for unlocking the latches 5, optional methods for retracting the tongues, and wiring structures 7. The latches 5 can be unlocked by a key mechanism (e.g., a key-operated lock cylinder) inserted into a key port 6 in the assembly MORT-300, MORT-500, MORT-700. Alternatively, the latches can be locked by a drive shaft inserted into a port 8 in the assembly MORT-400, MORT-600, MORT-800. The bolt 2 can be retracted by rotating the spindle inserted into the spindle hole 3, or by pulling the pull rod 4 in the retracting direction of the bolt 2. The hole 7 on the bottom plate 1 of the door lock assembly MORT-300, MORT-600, MORT-800 is used to route wires from the inside of its mortise lock assembly to the outside, thereby enabling connection between itself and externally connected components.

[0048] Figure 1 -A shows two short mortise lock door lock assemblies MORT-100, MORT-200, each of which is equipped with a deadbolt 2. The door lock assembly MORT-100 includes a spindle hole 3, into which a spindle connected to a drive unit such as a handle or a knob can be inserted. Engaging the drive unit rotates the spindle hole 3, thereby retracting the deadbolt 2. The other assembly MORT-200 has a pull rod 4, which retracts the deadbolt 2 when the pull rod 4 is pulled.

[0049] Figure 1-B shows two short mortise lock door lock assemblies MORT-300, MORT-400, each equipped with a latch 5. The door lock assembly MORT-400 allows the latch 5 to be actuated by inserting a drive shaft into a port 8, wherein rotating the shaft extends or retracts the latch 5. Similarly, the other assembly MORT-300 allows the latch 5 to be actuated by inserting a key mechanism into a key port 6, wherein rotating the key extends or retracts the latch 5. In addition, the assembly MORT-300 has a hole 7 for routing connecting wires through or into the assembly.

[0050] Figure 1 -C shows two high mortise lock door lock assemblies MORT-500, MORT-600, each equipped with a deadbolt 2 and a latch 5. In both assemblies, the deadbolt 2 is retracted by a spindle inserted into a spindle hole 3. However, the latch 5 is retracted or extended by rotating a key in a key port 6 or a drive shaft in a port 8. Assembly MORT-600 includes a hole 7 for passing wires through or into the assembly.

[0051] Figure 1 -D shows two mortise lock door lock assemblies MORT-700, MORT-800, each equipped with a deadbolt 2 and a latch 5. The deadbolt 2 in both assemblies is actuated by a pull rod 4. However, the latch 5 is retracted or extended by rotating a key in a key port 6 or a drive shaft in a port 8. Assembly MORT-800 includes a hole 7 for passing wires through or into the assembly.

[0052] Figure 2 ：

[0053] Figure 2 The short mortise lock door lock assembly MORT-900 with a lockable lock tongue 2 is shown in three states, wherein part E shows the lock tongue in its unlocked state, part F shows the lock tongue in its extended locked state, and part G shows the lock tongue in its retracted locked state.

[0054] The bolt 2 comprises a locking mechanism MECH-101, MECH-201, MECH-301, wherein a portion of the bolt 2 is enclosed inside the assembly MORT-900, provided with a slot 12 oriented perpendicular to the direction of movement of the bolt 2. A lug 11 is arranged above the slot 12, the lug 11 being attached to a shaft 10 extending from an actuator 9. The actuator 9 is capable of rotating the shaft 10 so that the lug 11 on the shaft 10 is inserted into the slot 12 of the bolt 2, thereby locking the bolt 2 in place.

[0055] Furthermore, the bolt 2 is attached to a shaft 13, which is guided by a fixing plate 15 in which a circular hole is arranged, so that the shaft 13 can move linearly, facilitating the extension and retraction of the bolt 2. The retraction of the bolt 2 compresses the spring 16 surrounding the shaft 13, exerting a force opposite to the retraction direction on the bolt 2. This ensures that the drive unit such as a handle or a knob of the bolt actuating mechanism MECH-102, MECH-202 is released, so that the bolt 2 returns to its position extended outside the assembly.

[0056] The bolt actuation mechanism MECH-102, MECH-202 comprises a circular plate 14 vertically attached to the bolt shaft 13. The circular plate 14 can be pushed by a lever 17 to move the bolt shaft 13 linearly in the direction of movement of the lever 17, thereby retracting the bolt 2. The lever 17 is attached to the spindle hole 3 into which the spindle can be inserted. A drive unit such as a handle or a knob coupled to the spindle can be engaged to actuate the lever.

[0057] When the bolt 2 is in the locked state, the bolt shaft 13 is also locked due to its connection with the bolt 2. At the same time, this locks the circular plate 14 attached to the bolt shaft 13, so that the plate 14 resists the push of the lever against it. This resistance effectively locks the bolt actuating mechanism MECH-102, MECH-202 and the combined handle, knob or other drive unit.

[0058] This structure allows the bolt 2 to be locked in two positions: its extended position, to secure the door in the closed state, and its retracted position, to lock the door in the open state.

[0059] Figure 2 -E shows a low profile mortise lock MORT-900 with the bolt 2 in its extended position. The bolt is locked by the tab and slot mechanism MECH-101, in an unlocked state in which the tab 11 is not inserted into the slot 12 in the bolt 2. In this state, the bolt 2 functions normally, as it can be retracted by operating the bolt actuating mechanism MECH-102. This mechanism can be operated by inserting a spindle into the spindle hole 3 and rotating a drive unit such as a knob or handle coupled to the spindle.

[0060] Figure 2 -F shows a low profile mortise lock MORT-900 with the bolt 2 in its extended position. The bolt is locked by means of a tab and slot mechanism MECH-201, wherein the tab 11 is inserted into a slot 12 in the bolt 2. In this locked state, the bolt 2 acts as a latch, preventing it from retracting into the door, thereby securing the door in the closed state. At the same time, the bolt actuating mechanism MECH-102 is also locked, wherein the circular plate 14 attached to the bolt shaft 13 is fixed in place. Therefore, any force applied by the lever 17 against the circular plate 14 will be resisted as long as the movement of the bolt 2 is restricted by the tab and slot mechanism MECH-201.

[0061] Figure 2 -G shows the short mortise lock assembly MORT-900 with the bolt 2 in its retracted position. The bolt is locked by means of the tab and slot mechanism MECH-301, wherein the tab 11 is inserted into the slot 12 in the bolt 2. In this locked and retracted state, the bolt 2 is fixed in the assembly MORT-900 and cannot be extended, forcing the door to remain open. In addition, the lever 17 of the bolt actuating mechanism MECH-202 is actuated so that it reaches the circular plate 14 of the bolt shaft 13. The bolt actuating mechanism MECH-202 is not locked, wherein the lever 17 is free to return to its non-actuated position.

[0062] Figure 3 ：

[0063] Figure 3 A short mortise lock door lock assembly MORT-1000 is shown, which encloses a bolt locking mechanism MECH-103, MECH-203, MECH-303, which causes the bolt actuator to disengage when locked. In the figure, part H shows that the bolt 2 is unlocked in its extended state, part I shows that the bolt 2 is locked in its extended state, and part J shows that the bolt 2 is locked in its retracted state.

[0064] The bolt 2 comprises a locking mechanism MECH-103, MECH-203, MECH-303, wherein the portion of the bolt 2 enclosed in the assembly MORT-1000 is provided with a slot 12 oriented perpendicularly to the direction of movement of the bolt 2. A lug 11 is arranged above the slot 12, the lug 11 being attached to a shaft 1010 which protrudes from the actuator 9. The actuator 9 is capable of rotating the shaft 1010 so that the lug 11 on the shaft 1010 can be inserted into the slot 12 in the bolt 2, thereby locking the bolt 2 in place.

[0065] In addition, the bolt 2 is attached to a separate shaft 1013, which is guided by a fixed plate 15 in which a circular hole is placed, so that the shaft 1013 can move linearly, facilitating the retraction and extension of the bolt 2. The retraction of the bolt 2 compresses the spring 16 surrounding the shaft 1013, exerting a force opposite to the retraction direction on the bolt 2. This ensures that when the drive unit of the bolt actuating mechanism MECH-104, MECH-204, MECH-304 is released, it pushes the bolt 2 outward, returning it to the extended position.

[0066] The bolt actuation mechanism MECH-104, MECH-204, MECH-304 comprises a plate 20 vertically attached to the bolt shaft 13. The plate 20 can be pushed by the lever 17, thereby causing the bolt shaft 13 to move linearly in the direction of movement of the lever 17, thereby retracting the bolt 2. The lever 17 is attached to the spindle hole 3, and a drive unit such as a spindle attached to the handle can be inserted into the spindle hole 3 to drive the mechanism.

[0067] When the plate 20 is arranged behind the lever 17, the plate 20 exerts pressure on the lever 17 backwards, and the upper section of the lever 17 rotates, causing the lever 17 to move back to its initial position. This causes the plate 20 to reset itself back to the front of the lever 17.

[0068] Attached to the bolt shaft 1013 is a gear 19 which meshes with a corresponding gear 18 on a different shaft 1010 extending from the actuator 9. When the actuator 9 turns the shaft 1010, it engages the tab 11 into the slot 12, rotating the gears 18, 19 at the same time. This gear interaction causes the bolt shaft 1013 to rotate. As a result, the plate 20 connected to the bolt shaft 1013 rotates so that it is no longer aligned with the lever 17. This misalignment prevents the lever 17 from interacting with the plate 20 of the bolt shaft 1013, thereby preventing the lever from actuating the bolt 2. This effectively separates the bolt actuating mechanism MECH-204, MECH-304 from the bolt 2.

[0069] This arrangement allows locking of the bolt 2 in its extended and retracted positions while disengaging the bolt actuating mechanism from the bolt.

[0070] Figure 3 -H shows a short mortise lock door lock assembly MORT-1000 with the bolt 2 in its extended position. The bolt is locked by a lug and slot mechanism MECH-103, which can facilitate the disengagement of the bolt actuator when locked. The bolt is in an unlocked state, wherein the lug 11 is not fitted into the slot 12 of the bolt 2. In addition, a plate 20 is attached to the bolt shaft 1013 and is placed in front of the lever 17 of the bolt actuating mechanism MECH-104. This enables the bolt actuating lever 17 to push against the plate 20, thereby allowing the bolt 2 to retract. In addition, the bolt actuating mechanism MECH-104 can be driven by inserting the spindle into the spindle hole 3 and actuating a drive unit such as a knob or handle connected to the spindle.

[0071] Figure 3-I shows a short mortise lock door lock assembly MORT-1000 with the deadbolt 2 in its extended position. The deadbolt 2 is locked by means of a tab and slot mechanism MECH-203, which is capable of facilitating the disengagement of the deadbolt actuation when locked. The deadbolt 2 is in a locked state when the tab 11 is inserted into a slot 12 in the deadbolt 2, wherein the tab 11 is attached to a shaft 1010 extending from the actuator 9, wherein the shaft 1010 is rotated, thereby rotating the tab 11. At the same time, the plate 20 connected to the deadbolt shaft 1013 is rotated so that it deviates from the lever 17 of the deadbolt actuation mechanism MECH-204, thereby forming a gap in front of the lever 17. As a result, the movement of the lever 17 no longer reaches the plate 20 and interacts with the plate 20, thereby disengaging the deadbolt actuation mechanism MECH-204 from the deadbolt itself.

[0072] Figure 3 -J shows a short mortise lock door lock assembly MORT-1000 with the deadbolt 2 in its retracted position. The deadbolt 2 is locked by means of a tab and slot mechanism MECH-303, which is capable of facilitating the disengagement of the deadbolt actuation when locked. The deadbolt 2 is in a locked state when the tab 11 is inserted into a slot 12 in the deadbolt 2, wherein the tab 11 is attached to a shaft 1010 extending from the actuator 9, wherein the shaft 1010 rotates, thereby rotating the tab. At the same time, the plate 20 attached to the deadbolt shaft 1013 is rotated so that it deviates from the lever 17 of the deadbolt actuation mechanism MECH-304, thereby forming a gap in front of the lever 17. Therefore, the movement of the lever 17 no longer reaches the plate 20 and interacts with the plate 20, thereby effectively disengaging the deadbolt actuation mechanism MECH-304 from the deadbolt itself.

[0073] Figure 4 ：

[0074] Figure 4 A short mortise lock door lock assembly MORT-1100 is shown with the bolt 2 in its extended position. The assembly encloses the bolt locking mechanism MECH-105, MECH-205, which promotes the disengagement of the bolt actuator when locked. In the figure, part K shows the bolt 2 in its unlocked state, while part L shows the bolt 2 in its locked state.

[0075] The bolt 2 comprises a locking mechanism MECH-105, MECH-205, wherein a portion of the bolt 2 enclosed in the interior of the assembly MORT-1100 is provided with a hole 21. The hole 21 is oriented perpendicular to the direction of movement of the bolt 2. A vertically oriented rack 22 is located below the hole 21, the rack 22 meshing with a pinion 23. The pinion is connected to a gear 24, which in turn meshes with a drive key 25. The drive key 25 can be rotated to trigger the movement of the gear 24, causing the pinion 23 to rotate, thereby causing a vertical movement of the rack. The upward movement of the rack 22 inserts it into the bolt 2, thereby locking the bolt 2 in place; on the other hand, the downward movement of the rack 22 retracts the rack 22 from the bolt 2, thereby effectively unlocking the bolt.

[0076] In addition, the bolt 2 is attached to a separate shaft 1113, which is guided by the fixing plate 15 in which the circular hole is placed, so that the shaft 1113 moves linearly, facilitating the retraction and extension of the bolt 2. The retraction of the bolt 2 compresses the spring 16 surrounding the shaft 1113, thereby exerting a force opposite to the retraction direction on the bolt 2. This ensures that when the drive unit of the bolt actuating mechanism MECH-107, MECH-207 is released, the force pushes the bolt 2 outward, returning the bolt 2 to the extended position.

[0077] The bolt actuation mechanism MECH-107, MECH-207 comprises a circular plate 26 attached vertically to the bolt shaft 1113. The plate 26 can be actuated by a lever 27, which in turn causes the bolt shaft 1113 to move linearly in the direction of the action of the lever 27, thereby retracting the bolt 2. The lever 27 is attached to the spindle hole 3, wherein a drive unit can be inserted into the spindle hole 3 to drive a mechanism such as a spindle connected to a handle.

[0078] The circular plate 26 has a cutout portion 40 which can be aligned with the lever 27 by rotation of the bolt shaft 1113. When aligned, the cutout portion 40 forms a gap in front of the lever, whereby the movement of the lever is unrestricted, preventing it from actuating the bolt 2. This effectively disengages the bolt actuating mechanism MECH-204, MECH-304 from the bolt 2.

[0079] The rod 30 protrudes through a hole on the periphery of the circular plate 26 so that the rod 30 is not affected by the linear movement of the circular plate 1026 in the direction of retraction of the bolt 2. The rod 30 is connected to the disengagement arm 28 by a pivot mechanism 31. The arm is coupled to the drive key 25 by a rack 29 located on its bottom edge, wherein the rotation of the drive key 25 causes the rack 29 to move vertically. This causes the vertical movement of the disengagement arm 28, thereby actuating the pivot mechanism 31. The mechanism 31 causes the rod 30 to rotate, which then applies a force that rotates the circular plate 26 attached to the bolt shaft 1113.

[0080] Turning the drive key 25 inserts the rack 22 into the hole in the bolt 2, thereby locking the bolt 2 in place. At the same time, this action actuates the disengagement arm 28, causing the bolt shaft 1113 and the circular plate 26 to rotate. This movement aligns the cutout portion 40 in the circular plate 26 with the lever 27 of the bolt actuator mechanism MECH-207, thereby disengaging the bolt actuator mechanism from the bolt 2. Conversely, turning the drive key 25 in the reverse direction retracts the rack, thereby unlocking the bolt 2. At the same time, the circular plate 1026 rotates so that the cutout portion 40 is no longer aligned with the lever 27, thereby effectively reengaging the bolt actuator mechanism.

[0081] This structure allows locking the bolt 2 in its extended position in position while disengaging the bolt actuating mechanism from the bolt 2 .

[0082] Figure 4 -K shows a short mortise lock door lock assembly MORT-1100 with the deadbolt 2 in its extended position. The deadbolt 2 is locked by a rack and pinion mechanism MECH-105, and when the deadbolt is locked, it is possible to facilitate the actuation disengagement of the deadbolt by a deadbolt disengagement mechanism MECH-106. The deadbolt 2 is in an unlocked state, wherein the drive key port 25 is not turned, and the rack 22 is in a retracted position so that it does not interact with the deadbolt. In addition, the cutout portion 40 of the circular plate 26 to which the deadbolt shaft 1113 is attached is not aligned with the lever of the deadbolt actuation mechanism MECH-107, and the deadbolt actuation mechanism MECH-107 is driven by inserting the spindle into the spindle hole 3 and rotating a drive unit such as a knob or handle, thereby causing the deadbolt to retract.

[0083] Figure 4 -L shows a short mortise lock door lock assembly MORT-1100 with the deadbolt 2 in its extended position. The deadbolt 2 is locked by a rack and pinion mechanism MECH-205, and when the deadbolt 2 is locked, it is possible to facilitate the actuation of the deadbolt by the deadbolt disengagement mechanism MECH-206. The deadbolt is in a locked state, wherein the drive key port 25 is turned to the left, thereby rotating the gear 24 and rotating the pinion 23. The rotation of the pinion causes the rack 22 to extend into the hole of the deadbolt, preventing it from moving backward, thereby effectively locking it in place. In addition, the circular plate 26 attached to the deadbolt shaft 1113 is rotated so that its cutout portion 40 is aligned with the lever 27 of the deadbolt actuation mechanism MECH-207, thereby forming a gap in front of the lever 27. Therefore, the movement of the lever 27 does not interact with the circular plate 26, thereby setting the deadbolt actuation mechanism MECH-207 to a state of disengagement from the deadbolt.

[0085] Figure 5The high mortise lock door lock assembly MORT-1200 is shown with the bolt 2 in its extended position. The assembly encloses the bolt locking mechanism MECH-108, MECH-208, facilitating the disengagement of the bolt actuator when locked. In the figure, part M shows the bolt 2 in its unlocked state, while part N shows the bolt 2 in its locked state.

[0086] The deadbolt locking mechanism MECH-108, MECH-208 comprises a locking rod 32 that can rotate about a fixed pivot point 33. One end of the locking rod 32 has an L-shaped design that is located below the deadbolt 2, allowing the locking rod 32 to lock and unlock the deadbolt 2. The other end of the locking rod 32 is connected to a rectangular plate 34. The rectangular plate 34 is mechanically coupled to a lock cylinder 35, wherein the rotation of a key 36 in the lock cylinder 35 causes a linear movement of the plate 34. The plate 34 in turn moves the locking rod 32, causing the locking rod 32 to rotate about the pivot point 33, such that the rotation of the locking rod 32 is opposite to the rotation of the key 36.

[0087] Turning the key 36 to the left moves the short side of the L-shaped end upward, placing the short side behind the bolt 2. This action limits the rearward movement of the bolt 2, effectively locking the bolt in place. Conversely, turning the key 36 to the right lowers the L-shaped end, thereby retracting the locking bar 32 from behind the bolt 2, allowing the bolt 2 to move backward, thereby unlocking it.

[0088] In addition, the bolt 2 is attached to the shaft 1213, the linear movement of which is guided by the fixed circular plate 1015 in which the circular hole is placed, thereby enabling the bolt 2 to be retracted and extended. The retraction of the bolt 2 compresses the spring 16 surrounding the shaft 1213, thereby exerting a force opposite to the retraction direction on the bolt 2. Therefore, this releases the drive unit of the bolt actuating mechanism MECH-1010, MECH-2010, causing the bolt 2 to return to the extension assembly MO RT-1200.

[0089] The bolt actuation mechanism MECH-1010, MECH-2010 comprises a circular plate 1026 attached vertically to the bolt shaft 1213. The plate 1026 can be actuated by a lever 1027, which in turn causes the bolt shaft 1213 to move linearly in the direction of the action of the lever 1027, thereby retracting the bolt 2. The lever 27 is attached to the spindle hole 3, wherein the drive unit can be inserted into the spindle hole 3 to drive a mechanism such as a spindle connected to the handle.

[0090] The circular plate 1026 has a cutout portion 1040 that can be aligned with the lever 27 by rotation of the bolt shaft 1213. When aligned, the cutout portion 1040 forms a gap in front of the lever 27, preventing the lever from actuating the bolt 2. This effectively disengages the bolt actuation mechanism MECH-1010, MECH-2010 from the bolt.

[0091] The rod 37 protrudes through a hole near the edge of the circular plate 1026, wherein the rod 37 is not affected by the linear movement of the circular plate 1026 in the retraction direction of the bolt 2. The rod 37 is attached to a disengagement arm 38, which is able to rotate about a pivot point 39. The arm 38 is associated with the rectangular plate 34 so that the horizontal movement of the plate 34 caused by the rotation of the key 36 in the lock cylinder 35 causes the disengagement arm 38 to rotate about the pivot point 39. The rotation of the disengagement arm 38 causes the rod 37 to exert a force on the circular plate 1026, thereby causing the shaft 1213 and the circular plate 1026 to rotate together.

[0092] Turning the key 36 in the lock cylinder 35 to the left actuates the locking bar 32 upward, thereby locking the deadbolt 2 in place. At the same time, this action actuates the disengagement arm 38, resulting in the rotation of the tongue shaft 1213 and the circular plate 1026. This movement aligns the cutout portion 1040 in the circular plate 1026 with the lever 1027 of the deadbolt actuating mechanism MECH-2010, thereby disengaging the mechanism from the deadbolt 2. Conversely, turning the key 36 to the right back to its initial state retracts the locking bar, thereby unlocking the deadbolt 2. At the same time, the circular plate 1026 rotates so that the cutout portion 1040 is no longer aligned with the lever 1027, thereby effectively reengaging the deadbolt actuating mechanism MECH-1010.

[0093] This structure allows locking the bolt 2 in its extended state while disengaging the bolt actuating mechanism from the bolt 2 .

[0094] Figure 5 -M shows a high mortise lock door lock assembly MORT-1200 with the bolt 2 in its extended position. The bolt 2 is locked by a locking rod mechanism MECH-108, and when locked, it is possible to facilitate the bolt actuator to disengage by a bolt disengagement mechanism MECH-109. The bolt 2 is in an unlocked state, wherein the key 26 in the lock cylinder 25 is not turned, and the locking rod 32 is in a retracted position, so that the locking rod 32 does not interact with the bolt 2. In addition, the circular plate 1026 attached to the bolt shaft 1213 is rotated so that its cutout portion 1040 deviates from the lever 1027 of the bolt actuation mechanism MECH-1010. This enables the bolt actuation rod 1027 to push against the circular plate 1026, thereby allowing the bolt 2 to retract. In addition, the bolt actuation mechanism MECH-1010 can be driven by inserting the spindle into the spindle hole 3 and actuating a drive unit such as a knob or handle connected to the spindle.

[0095] Figure 5-N shows a high mortise lock door lock assembly MORT-1200 with the deadbolt 2 in its extended position. The deadbolt 2 is locked by the locking rod mechanism MECH-208, and when locked, it can be realized by the deadbolt disengagement mechanism MECH-209 to promote the actuation of the deadbolt. The deadbolt 2 is in a locked state, wherein the key 26 in the lock cylinder 25 is turned to the left, so that the locking rod 32 extends behind the deadbolt 2. This prevents the deadbolt from moving backward, thereby locking the deadbolt in place. In addition, the circular plate 1026 attached to the deadbolt shaft 1213 is rotated so that its cutout portion 1040 is aligned with the lever 1027 of the deadbolt actuation mechanism MECH-1010, thereby forming a gap in front of the lever 1027. Therefore, the movement of the lever 1027 does not interact with the circular plate 1026, so that the deadbolt actuation mechanism MECH-2010 is disengaged from the deadbolt.

[0096] Detailed method (specific implementation method)

[0097] The utility model is characterized in that the door lock assembly MORT-900, MORT-1000, MORT-1100, MORT-1200 comprises a lock tongue 2 which can be retracted by a lock tongue actuating mechanism MECH-102, MECH-202, MECH-104, MECH-204, MECH-304, MECH-107, MECH-207, MECH-1010, MECH-2010. The lock tongue 2 can be locked in its extended position or retracted position by a lock tongue locking mechanism MECH-101, MECH-201, MECH-301, MECH-103, MECH-203, MECH-303, MECH-105, MECH-205, MECH-108, MECH-208 enclosed in the assembly.

[0098] The deadbolt can be locked by a tab and slot locking mechanism MECH-101, MECH-201, MECH-301, MECH-103, MECH-203, MECH-303, wherein the tab 11 moves or rotates to insert into the slot 12 in the deadbolt 2. The orientation of the tab 11 and the slot 12 should be such that inserting the tab 11 into the slot 12 in the deadbolt 2 limits the movement of the deadbolt 2. For example, Figure 2 and Figure 3 Door lock assemblies MORT-900, MORT-1000 are shown, which enclose a tab 11 mounted to a shaft 10, 100 extending from an actuator 9, so that rotation of the actuator causes the tab 11 to engage with a slot 12 in the bolt 2. The tab 11 and the slot 12 are perpendicular to the direction of movement of the bolt 2, thereby locking the bolt 2 in place. Rotating the shaft 10, 100 in the opposite direction disengages the tab 11 from the slot 12, thereby unlocking the bolt 2.

[0099] Similar mechanisms MECH-105, MECH-205 include a hole 21 in the bolt 2, wherein a rack 22, an arm or a rod can be inserted into the hole 21, preventing the bolt 2 from moving. For example, Figure 4 The door lock assembly MORT-1100 is shown, which encloses a rack 22 driven by a pinion 23, so that the rack 22 is inserted into and out of a hole 21 in the bolt 2. The pinion 23 meshes with a gear 24 connected to a drive key 25, wherein turning the drive key 25 moves the rack 2, thereby locking or unlocking the bolt 2.

[0100] Another mechanism MECH-108, MECH-208 involves a locking rod 32 that extends behind the bolt 2 to prevent the bolt from retracting. Figure 5 A door lock assembly MORT-1200 is shown, enclosing a locking bar 32 that can rotate about a pivot 33. In the locked state, the locking bar 32 extends behind the bolt 2, fixing it in the extended position. Rotating the locking bar 32 retracts it from behind the bolt 2, allowing the bolt 2 to move, thereby unlocking it. In this embodiment, the movement of the locking bar 32 is coupled to a rectangular plate 34. This rectangular plate 34 is mechanically associated with a lock cylinder 35, wherein turning a key 36 in the lock cylinder 35 moves the plate 34, thereby rotating the locking bar 32.

[0101] The door lock assembly MORT-1000, MORT-1100, MORT-1200 may have a bolt actuator disengagement mechanism MECH-103, MECH-203, MECH-303, MECH-106, MECH-206, MECH-109, MECH-209, wherein locking the bolt 2 causes the bolt 2 to be disengaged from its actuation mechanism MECH-204, MECH-304, MECH-207, MECH-2010. Thus, a drive unit of the bolt actuation mechanism, such as a knob or handle, can move freely independently of the bolt 2. This maintains a consistent user interaction as long as the bolt 2 can still be retracted when the bolt 5 is locked in the normal bolt operating assembly MECH-500, MECH-600, MECH-700, MECH-800.

[0102] exist Figure 3 , 4One method of disengaging a deadbolt 2 from a deadbolt actuating mechanism is outlined in and 5, wherein the deadbolt disengaging mechanism MECH-103, MECH-203, MECH-303, MECH-106, MECH-206, MECH-109, MECH-209 has a plate 20, 26, 1026 connected to a deadbolt shaft 1013, 1113, 1213. A portion of the plate 20, 26, 1026 is cut away or removed, resulting in a vacant space within the plate. Rotation of the shaft 1013, 1113, 1213 causes the plate 20, 26, 1026 to rotate, creating a gap in front of the deadbolt actuating lever 17, 27, 1027, effectively disengaging the deadbolt 2 from its actuating mechanism MECH-204, MECH-304, MECH-207, MECH-2010

[0103] exist Figure 3 In the disengagement mechanism MECH-103, MECH-203, MECH-303, a small plate 20 juxtaposed with a gear 19 is attached to the bolt shaft 1013. This gear meshes with another gear 18 provided on the actuator shaft 1010. Therefore, when the actuator shaft 1010 is rotated to lock the door by inserting the tab 11 into the slot 12 in the bolt 2, it simultaneously causes the rotation of the plate 20. This causes the disengagement of the bolt actuator mechanism MECH-204, MECH-304.

[0104] Alternatively, Figure 4 The disengagement mechanism MECH-106, MECH-206 includes a circular plate 26 having a cutout portion 40 attached to the bolt shaft 1113. The plate 26 is rotated by a rod 30, which is connected to an actuation disengagement arm 28 by a pivot mechanism 31. The disengagement arm 28 is associated with a drive key port 25. When the key is rotated in the drive key port 25, the rack 22 engages with the pinion 23 to lock the bolt. At the same time, the drive key port 25 moves the disengagement arm 28, resulting in the rotation of the circular plate 26, thereby disengaging the bolt actuation mechanism MECH-207.

[0105] Similarly, Figure 5 The disengagement mechanism MECH-109, MECH-209 comprises a circular plate 1026 having a cutout portion 1040 attached to the bolt shaft 1213. The plate 1026 is rotated by a rod 37 connected to a disengagement arm 38. The arm 38 is coupled to the rotation of the lock cylinder 35 inside the assembly MORT-1200. The rotation of the key 36 in the lock cylinder 35 will raise the locking rod 32 behind the bolt 2. At the same time, the movement moves the arm 38, causing the rotation of the circular plate 1026, thereby disengaging the bolt actuation mechanism MECH-2010.
