Description

Technical Field

[0001] The utility model relates to a door lock system, in particular to the combination of a battery pack in a mortise lock assembly. Background Art

[0002] Door lock systems, which typically include a mortise lock assembly and a pair of door handle assemblies, often require a power source for operating functions. Power may be required for one or both handle assemblies, the mortise lock assembly, or a combination thereof. Commonly, the power source is a battery or battery pack positioned within the door handle assembly, within the handle, or in the base plate. Under such an arrangement, power is distributed to other components of the door lock system through a connection to the handle assembly. However, such a placement of the battery pack in the handle assembly introduces several challenges including security vulnerabilities, technical limitations, usability issues, and aesthetic drawbacks.

[0003] Placing the battery pack in the floor or handle increases the risk of intentional or accidental tampering by someone with malicious intent. This vulnerability could render the door lock system inoperable, potentially leading to a state where the user is locked out. In severe cases, the entire door handle assembly may need to be replaced due to damage, implying significant usability issues. On the other hand, tampering could also compromise the security of the system, allowing unauthorized entry.

[0004] Additionally, due to the size of the battery, the allocated space for the battery within the handle assembly may result in a bulky design. Further, the configuration may require an unconventional layout in which the battery and other components of the door lock system may not be arranged in a typical or standard manner. Moreover, due to the incorporation of various functions into a limited space along with the battery, the design may be crowded and cluttered. Therefore, housing the battery within the handle assembly may negatively impact the aesthetic appeal of the product.

[0005] Further, the space constraints imposed by placing the battery in the handle assembly restrict the possibility of incorporating additional technical features into its assembly while maintaining an aesthetically pleasing design. Utility Model Content

[0006] Technical issues

[0007] In order to address the challenges caused by placing the battery of a door lock system into the base plate or handle of a door handle assembly, including safety risks due to possible battery tampering, technical limitations due to battery placement limiting the space for additional structural features, usability issues due to possible locking caused by tampering, and aesthetic issues due to a bulkier and crowded design, the utility model proposes the location of the battery within the mortise lock assembly of the door lock system.

[0008] Technical Solution

[0009] In addressing security vulnerabilities, usability issues, technical limitations, and aesthetic deficiencies, the present invention proposes the location of one or more batteries within the mortise lock assembly of a door lock system.

[0010] In such a position, components within the mortise lock assembly can be powered by the battery. In addition, the mortise lock assembly can distribute power to external components (e.g., a door handle assembly). This power distribution can be facilitated by electrical wires extending through a hole in the door to the exterior of the mortise lock assembly or by alternative means of power transmission.

[0011] The battery may be fixed within the mortise lock assembly or may be removable therefrom. In both cases, the battery may be non-rechargeable or rechargeable. When rechargeable, the battery may be recharged by an external component connected to the mortise lock assembly.

[0012] Considering that the front of the mortise lock assembly is accessible when the door is open, it is possible to have a method whereby the battery can be inserted and removed from the mortise lock assembly through the front of the mortise lock assembly to allow it to be replaced or recharged from the outside.

[0013] The battery may be inserted into a built-in battery housing within the mortise lock assembly, which is covered by a removable panel on the front face of the mortise lock assembly. Alternatively, the battery may be housed in a removable battery unit equipped with a connection port. The battery unit is designed to be inserted into the mortise lock assembly and connected to an associated connection port embedded within its mortise lock assembly.

[0014] One method of battery unit removal is to use a push-to-open mechanism, where pushing the battery unit inwardly results in a reverse action that pushes the battery unit out of the mortise lock assembly. Another method involves a slide-and-slide mechanism, where the battery unit slides in and out of the mortise lock assembly until the battery unit reaches its designated position. Alternatively, a mechanism similar to a SIM card ejector in a mobile phone can be used. This involves inserting a tool (called a battery ejection tool) into a hole on the front of the mortise lock assembly, which facilitates the ejection of the battery unit from the mortise lock assembly.

[0015] Therefore, the present invention features a mortise lock assembly wherein one or more batteries are disposed in the mortise lock assembly of the present invention.

[0016] The mortise lock assembly can be powered by one or more batteries, or can power other externally connected components from its batteries. In addition, the mortise lock assembly can both receive power from the battery and provide power to other components.

[0017] The mortise lock assembly may have one or more batteries secured within the mortise lock assembly.

[0018] In another aspect, the mortise lock assembly may have one or more batteries that are removable from the mortise lock assembly.

[0019] To enable removal of the batteries, the mortise lock assembly may include a built-in battery housing with a removable cover, wherein one or more batteries can be inserted and removed from the battery housing.

[0020] Alternatively, the mortise lock assembly may include a removable battery unit having a connection port that connects to a connection port built into the mortise lock assembly.

[0021] The battery unit can be removed from the front of the mortise lock assembly in various ways, including but not limited to: a SIM card ejection mechanism, a push ejection mechanism, and a slider slot mechanism.

[0022] Further, the battery unit may incorporate a battery that is detachable from the battery unit or a battery that is fixed in the battery unit.

[0023] In all cases, the battery unit or mortise lock assembly may have a rechargeable or non-rechargeable battery.

[0024] Beneficial Effects

[0025] The proposed location of the battery within the mortise lock assembly frees up space within the handle assembly, allowing room for additional technology components such as a keypad, camera, fingerprint sensor, additional power supply, and other modules.

[0026] Furthermore, the location of the one or more batteries within the mortise lock assembly enhances its tamper resistance. When the door is closed, the batteries are inaccessible, making it difficult for unauthorized personnel to tamper with it. Further, the configuration of the batteries within the mortise lock assembly ensures a continuous power supply, even if the door handle assemblies on both sides are forcibly removed. Such a continuous power supply is a crucial aspect, as it allows the mortise lock assembly to remain operational or trigger an alarm in the event of tampering.

[0027] Furthermore, placement of the power unit within the mortise lock assembly frees up space within the door lock handle assembly, thereby contributing to a more concise and aesthetically pleasing design without being crowded, cluttered or bulky.

[0028] An important aspect of such a configuration is the possibility of extended battery life, wherein a larger mortise lock assembly can accommodate a larger battery, thus allowing for increased battery capacity and reduced frequency of battery charging and replacement. Thus, the user benefits from increased usability as well as a sustained level of security. Furthermore, the placement of the battery within the mortise lock assembly also ensures that the external aesthetics are not compromised due to the size or shape of the battery.

[0042] DETAILED DESCRIPTION

[0043] Figures 1 to 6

[0044] For descriptive purposes, Figures 1 to 6Two groups of mortise lock assemblies are shown, each group comprising three mortise lock assemblies MORT-100, MORT-200, MORT-300, MORT-400, MORT-500, MORT-600: mortise lock assemblies of different sizes, configurations of bolts 3 and bolts 2 on these mortise lock assemblies, different key mechanism ports 5 for unlocking the bolts, drive shaft ports 6, and wiring holes 7. The bolts can be unlocked by a key mechanism (e.g. a key-operated cylinder) inserted into the key mechanism port 5, or by a drive shaft inserted into the drive shaft port 6 and driven by an actuator. The wiring holes 7 on the bottom plate 1 of the mortise lock assembly are intended to guide wires from the interior of the mortise lock assembly to the exterior thereof, so as to achieve connection between the mortise lock assembly and external connection components.

[0045] Figures 1 to 3 Three tall mortise lock assemblies MORT-100, MORT-200 and MORT-300 are shown, each having a bolt spindle hole 4 in a base plate 1 and a bolt 2 and a bolt 3 extending from the side of the base plate. These mortise lock assemblies differ in the following aspects: a key mechanism port 5 or a drive shaft port 6 for unlocking the bolt, and whether they have connecting wires extending to the outside of the mortise lock assembly through a wiring hole 7 in the base plate 1. One mortise lock assembly MORT-100 uses a key mechanism port 5 for inserting a key mechanism (e.g., a key-operated cylinder), while the other mortise lock assembly MORT-200, MORT-300 uses a drive shaft port 6 for inserting a drive shaft operated by an actuator. Both mortise lock assemblies MORT-100, MORT-200 have no wires extending to the outside thereof, while the other mortise lock assembly MORT-300 has wires extending to the outside thereof.

[0046] Figures 4 to 6 Three short mortise lock assemblies MORT-400, MORT-500 and MORT-600 are shown, each having a bolt 3 extending from the side of a base plate 1. These mortise lock assemblies differ in the key mechanism port 5 or drive shaft port 6 for unlocking the bolt, and whether they have connecting wires extending to the outside of the mortise lock assembly through a wiring hole 7 in the base plate 1. One mortise lock assembly MORT-400 uses a key mechanism port 5 for inserting a key mechanism (e.g., a key-operated cylinder), while the other mortise lock assemblies MORT-500, MORT-600 use a drive shaft port 6 for inserting a drive shaft operated by an actuator. Both mortise lock assemblies MORT-400, MORT-500 have no wires extending to the outside thereof, while the other mortise lock assembly MORT-600 has wires extending to the outside thereof.

[0047] Figure 7

[0048] Figure 7 An exploded view of an electromechanical door lock system is shown, including a mortise lock assembly MORT-700 disposed in a door, and two door handle assemblies HAS-1 and HAS-2 disposed on two sides S1 and S2 of the door.

[0049] The battery cover 14 is located on the front of the base plate 1 of the door handle assembly HAS-1, indicating that the battery is located in the assembly. The wire 9 extends out of the mortise lock assembly MORT-700 on both sides S1 and S2 of the door through the wiring hole 7 in the mortise lock assembly. The wire connects the mortise lock assembly MORT-700 to the two door handle assemblies HAS-1 and HAS-2 through the connector 13 on the base plate 1 of each door handle assembly. Such a configuration establishes an electrical connection between the door handle assemblies HAS-1 and HAS-2 on both sides S1 and S2 of the door and the mortise lock assembly MORT-700 inside the door, wherein considering that the door handle assembly HAS-2 accommodates the battery, the door handle assembly HAS-2 is used as a power source.

[0050] The drive shaft 15 extends from the door handle assembly HAS-1 to be inserted into the drive shaft port 6 on the base plate 1 of the mortise lock assembly MORT-700, providing mechanical control of the bolt 3 for the door handle assembly.

[0051] The spindle 8 extends from the base plate 1 of the door handle assembly HAS-1 on one side S1 of the door and is intended to be inserted through the bolt spindle hole 4 in the mortise lock assembly MORT-700. It is then intended to be inserted into the door handle base plate spindle hole 12 on the base plate 1 of the door handle assembly HAS-2 on the opposite side S2 of the door. The connection of the spindle 8 with the bolt spindle hole 4 and the door handle base plate spindle hole 12 establishes a mechanical connection between the door handle assemblies HAS-1, HAS-2 and the mortise lock assembly MORT-700. Therefore, the rotation of the door handle 10 causes the linear movement of the bolt 2.

[0052] Figures 8 to 12

[0053] Figures 8 to 12 The battery position in the mortise lock assembly MORT-800, MORT-900, MORT-1000, MORT-1100, MORT-1200 proposed by the utility model is shown, which is used to permanently fix the battery 16, the removable cylindrical battery 33 and the removable battery units BAT-100, BAT-200, BAT-300. Figures 8 to 12 Depicts the various ways in which batteries and battery cells may be disassembled.

[0054] Figure 8A mortise lock assembly MORT-800 is shown, the upper portion of which includes a bolt 2, a bolt 3, a bolt spindle hole 4, and a drive shaft port 6 for inserting a drive shaft for unlocking the bolt 3. A cross-sectional view of the lower half of the mortise lock assembly is shown, wherein a permanently fixed battery 16 is housed inside the mortise lock assembly MORT-800. This forms an electrical connection with the mortise lock assembly, wherein the electrical connection is subsequently transferred to the outside of the mortise lock assembly MORT-800 by wires 17 passing through wiring holes 7. These wires 17 extending to the outside of the mortise lock assembly enable external components such as a door handle assembly to receive power from the battery and provide power to recharge the battery (if the battery is rechargeable).

[0055] Fig. 9 A mortise lock assembly MORT-900 is shown, the upper portion of which includes a bolt 3 and a drive shaft port 6 for inserting a drive shaft that controls the bolt 3. A cross-sectional view of the lower portion of the mortise lock assembly is shown, wherein a battery unit BAT-100 is inserted within the mortise lock assembly MORT-900. The battery connection port 19 of the battery unit BAT-100 is connected to the embedded mortise lock assembly connection port 18. The wires 17 are shown connected to the mortise lock assembly connection port 18, form an electrical connection with the mortise lock assembly, and are subsequently transferred to the outside of the mortise lock assembly through the wiring hole 7. These wires 17 extending to the outside of the mortise lock assembly MORT-900 enable external components such as the door handle assembly to receive power from the battery unit BAT-100 and provide power to recharge the battery unit (if the battery unit is rechargeable).

[0056] The mortise lock assembly MORT-900 has a battery ejection mechanism MECH-1, wherein inserting a battery ejection tool 25 into an ejection tool hole 26 in the mortise lock assembly MORT-900 moves the linear shaft 24 toward the rotary lever 22. This movement applies pressure to the rotary lever 22, triggering it to rotate about the pivot 23. This rotation causes the rotary lever 22 to apply force to the battery BAT-100, pushing it outward from the interior of the mortise lock assembly MORT-900, thereby effectively ejecting the battery.

[0057] Fig.10A mortise lock assembly MORT-1000 is shown, the upper portion of which includes a bolt 2, a bolt spindle hole 4, a bolt 3, and a drive shaft port 6 for inserting a drive shaft that controls the bolt 3. A cross-sectional view of the lower portion of the mortise lock assembly is shown, wherein a battery unit BAT-200 is inserted into the mortise lock assembly MORT-1000. The battery connection port 19 on the battery unit BAT-200 is connected to a mortise lock assembly connection port 18 embedded in the mortise lock assembly. Wires 17 are shown connected to the mortise lock assembly connection port 18, forming an electrical connection with the mortise lock assembly, and then transferred to the outside of the mortise lock assembly through the wiring hole 7. These wires 17 extending to the outside of the mortise lock assembly MORT-1000 enable external components such as a door handle assembly to receive power from the battery unit BAT-200 and provide power to recharge the battery unit (if the battery unit is rechargeable).

[0058] The mortise lock assembly MORT-1000 has a push-to-pop mechanism MECH-2, wherein the insertion of the battery unit BAT-200 into the mortise lock assembly MORT-1000 presses the spring loaded push-to-open loading spring 27. This compresses the loading spring until it reaches the critical point where the latch of the actuator engages, thereby securing the battery unit BAT-200 in place. When secured in the mortise lock assembly, further pressing the battery unit BAT-200 inwardly further compresses the loading spring 27, which disengages the latch. When the latch disengages, the loading spring 27 pushes the battery unit BAT-200 out of the mortise lock assembly MORT-1000, thereby ejecting it.

[0059] Fig.11 The mortise lock assembly MORT-1100 is shown, the upper portion of which includes a bolt 2, a bolt shaft hole 4, a bolt 3, and a drive shaft port 6 for inserting a drive shaft that controls the bolt 3. A cross-sectional view of the lower portion of the mortise lock assembly is shown, wherein a battery unit BAT-300 is inserted into the mortise lock assembly MORT-1100. The battery connection port 19 on the battery unit BAT-300 is connected to the mortise lock assembly connection port 18 embedded in the mortise lock assembly. The wires 17 are shown connected to the mortise lock assembly connection port 18, form an electrical connection with the mortise lock assembly, and are subsequently transferred to the outside of the mortise lock assembly through the wiring hole 7. These wires 17 extending to the outside of the mortise lock assembly MORT-1100 enable external components such as the door handle assembly to receive power from the battery unit BAT-300 and provide power to recharge the battery unit (if the battery unit is rechargeable).

[0060] The mortise lock assembly MORT-1100 allows a slider slide action for insertion and removal of the battery unit BAT-300, wherein the front panel 29 of the battery unit BAT-300 has a finger groove 28 for grasping the battery unit and sliding it in and out of place.

[0061] Fig.12 A mortise lock assembly MORT-1200 is shown, the upper portion of which includes a bolt 2, a bolt shaft hole 4, a bolt 3, and a drive shaft port 6 for inserting a drive shaft for unlocking the bolt 3. A cross-sectional view of the lower portion of the mortise lock assembly is shown, wherein the mortise lock assembly houses a built-in embedded battery housing 34. This forms an electrical connection to the mortise lock assembly, which is then transferred to the outside of the mortise lock assembly MORT-1200 by wires 17 passing through the wiring holes 7. These wires 17 extending to the outside of the mortise lock assembly MORT-1200 enable external components such as the handle assembly to receive power from the battery and provide power to recharge the battery (if the battery is rechargeable).

[0062] The embedded battery case 34 houses five removable cylindrical batteries 33. In addition, the embedded battery case 34 has a removable front panel 29 that can be attached to or removed from the body of the battery case with screws 31. These screws fit into corresponding screw holes 32 located on the battery case 34. Removal of the front panel 29 allows access, removal, and replacement of the batteries 33. The front panel 29 has battery connection pads 30 that complete the circuit between the cylindrical batteries 33 and the embedded battery case 34 when the front panel is attached.

[0063] Figure 13 to Figure 16

[0064] Figure 13 to Figure 16 Different configurations of detachable battery units BAT-400, BAT-500, BAT-600, BAT-700 are shown. These configurations include batteries housed in a battery housing 35, wherein the batteries are rectangular rechargeable batteries 37, cylindrical rechargeable batteries 38, or cylindrical non-rechargeable batteries 39, rectangular non-rechargeable batteries 40. In addition, these batteries can be connected to the battery connection port 19 directly or indirectly through the power management unit 36.

[0065] Fig.13 and Fig.14 Two removable battery cells BAT-400, BAT-500 are shown, whose battery housing 35 accommodates either a rectangular rechargeable battery cell 37 or a cylindrical rechargeable battery cell 38, demonstrating that different configurations of different rechargeable battery types are possible.

[0066] The rectangular battery 37 in the battery unit BAT-400 is connected to a power management unit 36. The power management unit 36 ​​manages the power usage, recharges the battery and ensures the battery protection. In addition, the power management unit 36 ​​is connected to the battery connection port 19 to allow: connecting the battery unit to the mortise lock assembly or adapter, recharging the battery unit, protecting the battery unit and communicating with the battery unit.

[0067] The cylindrical rechargeable battery cells 38 within the battery unit BAT-500 are directly connected to the battery connection port 19 without the need for an intermediate power management unit. Therefore, the responsibility for charging and protecting the battery unit BAT-500 falls entirely on the external charging adapter or mortise lock assembly. Further, these cylindrical batteries are designed to be removable from the battery unit BAT-500. Therefore, this allows the battery 38 to be charged using an external charger and enables battery replacement.

[0068] Fig.15 and Fig.16 Two types of removable battery units BAT-600, BAT-700 are shown, each having a battery housing 35 that can accommodate either a rectangular non-rechargeable battery unit 40 or a cylindrical non-rechargeable battery unit 39. This demonstrates the ability to use different non-rechargeable batteries in different configurations. In these units BAT-600, BAT-700, the cylindrical non-rechargeable battery unit 39, the rectangular non-rechargeable battery unit 40 are directly connected to the battery connection port 19 to enable the battery unit to be connected to the mortise lock assembly.

[0069] The cylindrical non-rechargeable battery cell 39 in the battery cell BAT-600 is designed to be detachable from the battery cell BAT-600. Therefore, this allows the cylindrical non-rechargeable battery cell 39 to be replaced when exhausted. On the other hand, the rectangular non-rechargeable battery cell 40 is fixed and cannot be detached from the battery cell BAT-700, so when the rectangular non-rechargeable battery cell 40 is exhausted, the entire battery cell BAT-700 needs to be replaced.

[0085] Detailed method (specific implementation method)

[0086] The utility model is characterized in that a mortise lock assembly MORT-800, MORT-900, MORT-1000, MORT-1100, MORT-1200, MORT-1300, MORT-1400, MORT-1500 of a door lock is provided, and a battery 16, 33, BAT-100, BAT-200, BAT-300, BAT-400, BAT-500, BAT-600, BAT-700, BAT-10300, BAT-11300, BAT-12300 is accommodated in the mortise lock assembly. The mortise lock assembly receives power from the battery and can transfer the power to the outside of the mortise lock assembly, which is achieved by a wire 17 guided through a designated wiring hole 7 on a bottom plate 1 of the mortise lock assembly.

[0087] The one or more batteries 16, 33, BAT-100, BAT-200, BAT-300, BAT-400, BAT-500, BAT-600, BAT-700, BAT-10300, BAT-11300, BAT-12300 within the mortise lock assembly MORT-800, MORT-900, MORT-1000, MORT-1100, MORT-1200, MORT-1300, MORT-1400, MORT-1500 may be rechargeable batteries or non-rechargeable batteries. When rechargeable, the battery may be recharged from outside the mortise lock assembly via a wire 17 leading to the outside of the mortise lock assembly. For example, the handle assembly may be connected to a power source and manage the charging of the battery inside the mortise lock assembly.

[0088] One or more permanently fixed batteries 16 may be permanently disposed within the mortise lock assembly MORT-800. In such a case, there are two modes: the battery is rechargeable and is charged by an external power source connected to the mortise lock assembly by a wire 17; or the battery is non-rechargeable. These configurations are suitable for use in situations where battery replacement is not feasible, such as high security or inaccessible environments.

[0089] Alternatively, one or more cylindrical batteries 33, removable battery cells BAT-100, BAT-200, BAT-300, BAT-400, BAT-500, BAT-600, BAT-700, BAT-10300, BAT-11300, BAT-12300 may be removable from the mortise lock assembly MORT-900, MORT-1000, MORT-1100, MORT-1200, MORT-1300, MORT-1400, MORT-1500. One method of incorporating a removable battery is through a battery housing 34 embedded within the mortise lock assembly MORT-1200 having a removable front panel 29. Removal of the front panel 29 of the battery housing allows the cylindrical battery 33 or other shapes and forms of batteries to be inserted into and removed from the mortise lock assembly.

[0090] Another method of having a removable battery is through a removable battery unit BAT-100, BAT-200, BAT-300, BAT-400, BAT-500, BAT-600, BAT-700, BAT-10300, BAT-11300, BAT-12300 that can be inserted into a mortise lock assembly MORT-900, MORT-1000, MORT-1100, MORT-1200, MORT-1300, MORT-1400, MORT-1500 and removed therefrom. The removable battery unit mainly includes a battery rectangular rechargeable battery unit 37, a cylindrical rechargeable battery unit 38, a cylindrical non-rechargeable battery unit 39, a rectangular non-rechargeable battery unit 40, and a battery connection port 19. When the battery unit is inserted into the mortise lock assembly, the battery connection port on the battery unit is connected to the mortise lock assembly connection port 18 embedded in the mortise lock assembly. Therefore, when the battery unit is removed from the mortise lock assembly, it is disconnected from the mortise lock assembly connection port 18 .

[0091] The removable battery cell BAT-100, BAT-200, BAT-300, BAT-400, BAT-500, BAT-600, BAT-700, BAT-10300, BAT-11300, BAT-12300 may have a rectangular rechargeable battery cell 37, a cylindrical rechargeable battery cell 38, or a non-rechargeable cylindrical non-rechargeable battery cell 39, a rectangular non-rechargeable battery cell 40. When non-rechargeable, the removable battery cell BAT-600 may allow the battery to be removable. This provides an option to replace the cylindrical non-rechargeable battery cell 39 in the battery cell BAT-600 when the battery is exhausted. Alternatively, the rectangular non-rechargeable battery cell 40 in the battery cell BAT-700 may be fixed and not allow battery replacement, in which case the user must obtain a new battery cell when the rectangular non-rechargeable battery cell 40 is exhausted.

[0092] Similarly, when rechargeable, the battery unit BAT-500, BAT-600 can allow the battery cylindrical rechargeable battery unit 38, cylindrical non-rechargeable battery unit 39 to be removed from the mortise lock assembly. This provides the option of replacing a depleted battery and recharging the depleted battery independently of the battery unit, where the battery connection port 19 of the unit is not used. In the case where the rectangular rechargeable battery unit 37 is not removable, the battery unit BAT-400 allows the rectangular rechargeable battery unit 37 to be charged by connecting a power source to the battery connection port 19 of the battery unit.

[0093] These battery configurations allow for removal of a depleted battery, replacement of the depleted battery with a rechargeable or non-rechargeable charged battery, wherein the depleted battery can be recharged. Removal of the battery unit from the mortise lock assembly can be performed by a variety of different mechanisms.

[0094] One method of ejecting the battery unit from the mortise lock assembly is a battery ejection mechanism MECH-1 similar to a SIM card ejection mechanism, whereby a battery ejection tool 25 is inserted into an ejection tool hole 26 in the mortise lock assembly MORT-900, causing the battery BAT-100 to be ejected. Figure 3E is shown, where the insertion of the battery ejection tool 25 causes the linear shaft 24 to move, which then pushes on the rotary lever 22. This action applies a force to the rotary lever, causing it to rotate about the pivot 23. The rotation of the rotary lever pushes on the battery unit BAT-100, causing the battery unit to slide to the outside of the mortise lock assembly MORT-900, thereby ejecting it. In turn, the insertion of the battery unit BAT-100 into the mortise lock assembly is opposite to this movement, whereby the battery presses on the rotary lever 22, causing the rotary lever to rotate in the opposite direction, thereby returning the ejection mechanism MECH-1 to its initial resting state, as shown in FIG. Fig. 9 shown.

[0095] Alternatively, the push-to-pop mechanism MECH-2 facilitates the insertion and removal of the battery unit BAT-200 from the mortise lock assembly MORT-1000 by a pressing and releasing action. In one embodiment, when the user presses the battery unit BAT-200 into the mortise lock assembly MORT-1000, the battery unit presses on the spring-loaded push-to-pop actuator 27 until it reaches a critical point, whereby the latch mechanism on the actuator 27 is actuated. When actuated, the latch secures the battery unit in place. Conversely, when the battery unit BAT-200 is inside the mortise lock assembly MORT-1000, pressing the battery unit inwardly will disable the latch mechanism of the spring-loaded push-to-pop actuator 27. This failure triggers the spring mechanism, which then applies an outward force on the battery unit BAT-200, thereby effectively ejecting the battery unit from the mortise lock assembly MORT-1000.

[0096] For a simpler solution, the slider-slot action allows the battery unit BAT-300 to be inserted into the mortise lock assembly MORT-1100 by sliding the battery unit BAT-300 into the mortise lock assembly MORT-1100 and allows it to be removed by grasping and pulling it out. This mode of operation is as follows Fig.11 As shown, the front side 21 of the battery unit is provided with gripping finger grooves 28. These finger grooves enable the user to firmly grasp the battery with his fingers, thereby allowing the battery to be removed from the mortise lock assembly.

[0097] In summary, the present invention provides a range of options for incorporating a battery into a mortise lock assembly and managing its power.
