Description

field of technology

[0001] The invention relates to a lock with a housing comprising a faceplate, a lock base, and a lock top, and with an energy converter arranged on the faceplate between the lock base and the lock top, which converts mechanical work expended to operate the lock into electrical energy. Furthermore, the invention relates to the use of an assembly comprising an energy converter housing with an energy converter arranged therein, for upgrading a purely mechanical lock to a wireless lock. State of the art

[0002] A lock of this design is described in DE 10 2020 103 323 A1. The energy converter is spatially arranged between a latch and a bolt and can be activated by either actuating the latch or the bolt. This action, through the displacement of a movable element, such as a magnet, relative to the base of the energy converter, generates an energy pulse. This energy pulse can then be used to operate a radio module, which transmits the lock's closed state to a central unit. In the prior art, the energy converter is permanently installed within the lock housing and cannot be replaced without opening the housing. Summary of the invention

[0003] The invention is based on the objective of simplifying the replacement or retrofitting of the energy converter.

[0004] The problem is solved by the invention specified in the claims, wherein the dependent claims are not only advantageous further developments of the invention specified in the dependent claims, but also represent independent solutions to the problem.

[0005] The invention primarily relates to the spatial arrangement of the energy converter within the lock housing. The energy converter is preferably arranged between the latch and the bolt, as is generally known from DE 10 2020 103 323 A1. The energy converter is located between the lock top and the lock bottom and adjoins a faceplate. To retrofit a lock with an energy converter or a radio module, it is proposed that the energy converter be arranged in an energy converter housing. The latter can be an assembly that can be inserted into the lock housing through a recess in the lock top. According to the invention, this is done without disassembling the lock top. Preferably, the assembly is inserted into the lock housing through the recess in the lock top by means of a rotary motion. The assembly can be made of plastic and include the radio module. It can have an antenna.The antenna is preferably arranged in a projection that, when the energy converter housing is installed, sits in a window of the strike plate. The energy converter housing can form a cover that closes the recess when the assembly is mounted. The base of the lock housing can form a window into which a rear projection of the energy converter housing can engage. The energy converter housing is preferably mounted by a pivoting or rotating movement, in which the projection containing the antenna is first inserted into the window of the strike plate, and then the rear projection engages in the window of the base. When mounted, the recess in the lock top is closed by a cover of the energy converter housing.

[0006] The assembly can comprise a first element in the form of an energy converter housing, which can be attached to the base of the lock housing by means of fastening screws engaging in threaded holes. An extension, featuring an antenna, is located on an end face of the energy converter housing facing the strike plate and can engage in a window of the strike plate. To facilitate the assembly described above, it is proposed that the extension be slidably attached to the energy converter housing. Specifically, it is provided that the extension is slidably attached to the energy converter housing in a direction transverse to the direction of extension of the strike plate. This allows for multi-stage assembly of the unit.

[0007] The assembly is initially inserted through the recess in the lock top in a tilted position. The extension is then inserted into the window of the strike plate. The assembly is then pivoted into its final pivoted position. In this position, the extension containing the antenna only partially engages the window. The cover is not yet fully inserted into the recess. The lower extension is also not yet inserted into the window of the base. Starting from this intermediate position, the assembly is moved parallel to the direction of the base until the extension containing the antenna is fully positioned in the window. Now the energy converter housing can be moved relative to the extension until the lower extension engages in the window of the lock base and the cover closes the recess in the lock top.

[0008] Hooks can be provided for the sliding arrangement of the extension on the energy converter housing, projecting into a guide opening. The guide opening is preferably formed by the energy converter housing. The hook is formed by the extension. The energy converter housing can have a guide opening extending in the sliding direction of the extension, which has the form of a slot. Adjacent to this is a guide flank engaged by a retaining element of the extension. This can be a dovetail-like hook engagement.

[0009] It may be provided that the extension is a hollow plastic cap, in the cavity of which the antenna is arranged.

[0010] Preferably, the assembly can be inserted into the lock housing through the recess in the lock ceiling by means of a rotary or swiveling movement.

[0011] In particular, it is provided that the energy converter housing has only a mechanical interface in the form of a release tongue of the energy converter, by actuating which a radio signal can be sent.

[0012] The assembly can be inserted in a tilted position through the recess, whereby first the extension can be inserted into a window of the mullion and then the assembly can be pivoted into a final position.

[0013] The energy converter housing can be made of plastic.

[0014] An energy storage device, in particular a capacitor, can be arranged in the energy converter housing, in which an energy pulse generated by the energy converter is temporarily stored.

[0015] The lock can be operated as a purely mechanical lock without the module. By inserting the module, the lock can be upgraded to a wireless lock.

[0016] In a preferred embodiment, the motion transmission element performs the forward and return movements during the bolt's extension and / or retraction. While in the prior art the movable element of the energy converter is only retracted during the bolt's retraction, according to the invention this retraction occurs during the bolt's extension. When the bolt is retracted from the extended position, the motion transmission element can also perform a forward and a return movement. According to a first embodiment of the invention, the movement of the motion transmission element is derived from the bolt's movement. The bolt is coupled to the motion transmission element such that, in a first phase of the bolt's extension or retraction, it performs the forward movement, and in the immediately following second phase, it performs the return movement.This is preferably achieved via a cam mechanism. The cam mechanism can be a slotted pin mechanism. However, the cam mechanism can also simply consist of a cam. The cam is shaped or curved such that the motion transmission element performs the forward movement during the first rotation of a two-rotation locking bolt and the return movement during the second rotation. It is advantageous if the motion transmission element is a lever mounted on the housing. This lever can incorporate the cam. The cam can interact with a cam pin attached to the housing. The cam can have a first section along which the cam pin slides during the first locking bolt movement, causing the motion transmission element to pivot, thus displacing the movable element.The cam track can have a second section, which the cam pin reaches after the first bolt extension is complete. The cam track can have a third section, along which the cam pin slides during the second bolt extension, causing the motion transfer element to pivot in the opposite direction, allowing the movable element to retract. This movement occurs in reverse during bolt retraction. The motion transfer element can be a flat metal piece with one broad side against the inner wall of the lock base or top. The motion transfer element can be located between the bolt and the lock base or top. The cam pin, which interacts with the cam track or engages in a cam slot, can project from one broad side of the bolt.The bolt can be rotated by turning a key or a lock cylinder. The key's locking blade or the locking element of the lock cylinder engages in turning recesses in the bolt tail to fully extend or retract the bolt with two complete turns of the lock cylinder or key, respectively. A detent may be provided that is disengaged when the key or lock cylinder is turned and otherwise blocks the bolt's movement. The motion transmission element can act directly on the energy converter, for example, on a release tongue of the energy converter. Preferably, however, the motion transmission element acts on a trigger, which may be designed as a pivot lever. Preferably, the trigger is a two-armed lever. The trigger is preferably rotatable about a housing-fixed pivot axis and may be actuated by a spring element.The spring element is preferably arranged such that it holds an actuating projection, with which the trigger interacts with the energy converter, in a position away from the energy converter. The motion transmission element can have an actuating section, for example, a lug, that engages a free end of the trigger to move the trigger towards the energy converter during the forward movement. During the return movement of the motion transmission element, the spring element can move the trigger away from the energy converter, so that the two movements of the movable element of the energy converter described above can occur during bolt extension or bolt retraction. The trigger can have a second end that interacts with a shoulder of a latch, so that the trigger is also moved during latch retraction to initially move the movable element of the energy converter into the device.When the latch is advanced by a spring, the trigger moves back, allowing a pre-tensioned spring in the energy converter to retract the movable element. In a second embodiment of the invention, particularly relevant for locksmiths where the bolt can only be advanced once, the motion transmission element can be a tumbler. The tumbler's function is to prevent bolt movement, so that bolt advance or retraction can only occur after the tumbler has been disengaged. The tumbler is disengaged using the bit of the key or the locking element of the cylinder. This engages the tumbler and lifts it in a direction transverse to the bolt's movement, thus releasing the bolt's movement.Once the bolt has been advanced by the rotation of the key or the lock cylinder, the tumbler is returned to its blocking position, for example by a tumbler spring, in which movement of the bolt is blocked. According to the invention, the tumbler has an actuating section, which can be formed by a shoulder, a control cam, or a lug, that engages the trigger to relocate the trigger when the tumbler is lifted. The trigger engages, for example with an actuating projection, a release tongue of the energy converter in the manner described above to relocate the movable element of the energy converter. If the tumbler is retracted, for example by the tumbler spring, the trigger can pivot back, for example by the force of a previously tensioned spring. The movable element of the energy converter can then retract.Here too, the energy converter is activated during both the forward and reverse locking of the bolt, specifically whenever the locking pin performs an up-and-down movement. The second variant can also be used with a two-turn locking mechanism. In this case, the movable element of the energy converter is moved back and forth during each turn, both when the bolt is forwarded and when it is reversed.

[0017] Furthermore, the invention relates to the use of an assembly comprising an energy converter housing with an energy converter arranged therein, for upgrading a purely mechanical lock to a wireless lock. It is proposed in this regard that the assembly be inserted into the lock housing through a recess in the lock cover without opening the lock housing. Brief description of the drawings

Description of the embodiments

[0019] The Figures 1 to 10 Figure 1 shows a first embodiment of an interior door lock comprising a faceplate 21, a lock base 22, and a lock cover 23. The faceplate 21 has a window for the passage of the head of a latch 32 and another window for the passage of the head of a bolt 3. A window 26 is located between these two windows.

[0020] In the exemplary embodiment, the lock can be operated by a locking cylinder which has a locking element 16 which engages a bolt tail 3' of the bolt 3 in order to fully extend the bolt 3 in two successive phases, during which the bolt 3 is advanced by one turn in each phase.

[0021] A cam pin 7 projects from a broad side face of the bolt 3 and engages in a cam slot 6 of a motion transmission element 5 formed by a flat metal piece. The motion transmission element 5 lies between the lock base 22 and the broad side face of the bolt 3. The cam slot 6 has several sections, each with different directions of extension. The motion transmission element 5 is pivotally mounted on the lock base 22 about a pivot axis 8. It is essentially completely covered by the bolt 3, with only a lug 9 projecting beyond the upper edge of the bolt 3. This lug 9 forms an actuating section.

[0022] In the Figure 3 In the illustrated closed position, in which the bolt 3 is fully retracted, the nose 9 protrudes only slightly beyond the upper edge of the bolt 3. If the bolt 3 is moved into the position shown by rotating the locking element 16 by one turn, the nose 9 protrudes only slightly beyond the upper edge of the bolt 3. Figure 5 If the operating position shown is shifted forward, the cam pin 7 projecting from the broad side surface of the bolt 3 slides in a first slot section 6' of the cam slot 6, the first section 6' having such a direction that the motion transmission element 5 is pivoted upwards, so that the nose 9 lifts up.

[0023] After the first bolt advance, the cam pin 7 reaches the second slot section 6", which has a neutral direction. If the cam pin 7 is moved in this second slot section 6", the pivot position of the motion transmission element 5 does not change.

[0024] Is bar 3 from the one in the Figure 5 The intermediate position shown is achieved by a further rotation of the closing element 16 by a second turn until it reaches the position shown in the Figure 6If the illustrated operating position is pivoted, the cam pin 7 slides through the third slot section 6‴ of the cam slot 6, which has such an inclination that the motion transmission element 5 returns to the initial position ( Figure 3 ) is moved back.

[0025] When the bolt 3 is moved from a fully retracted position to a fully forward-closed position, the motion transmission element 5 thus performs a forward movement and a return movement. This also occurs when the bolt 3 is moved from the position in the Figure 6 depicted fully closed position back into the in the Figure 3 The depicted position is shifted to a completely withdrawn position.

[0026] Inside the lock housing is another lever, designated as the release 4. The release 4 has a first free end 4', which is actuated by the actuating section, i.e., the lug 9 of the motion transmission element 5. The edge of the motion transmission element 5 engages an edge 4" of the release 4. The release 4 is actuated by a torsion spring 14 such that the edge 4" can bear against the lug 9. When the motion transmission element 5 moves as described above, the release 4 thus performs a reciprocating motion, the forward movement being derived from the pivoting motion of the motion transmission element 5, during which the spring element 14 is tensioned, and the return movement being caused by the tensioning of the spring element 14.

[0027] The trigger 4 forms an actuating projection 19, which has a metal sheath 19'. This actuating projection 19 can be used to actuate an energy converter 2 to generate electrical power in the form of a current / voltage pulse. The energy converter 2 has a base body 13, which is fixedly connected to the housing 1. One or more coils can be arranged in the base body 13. The energy converter 2 has a movable element 12 relative to the base body 13, which can be a magnet. When the movable element 12 is displaced relative to the base body 13, the energy converter 2 generates a power pulse, the magnitude of which depends in particular on the displacement speed.

[0028] The energy converter 2 has an actuating spring 20, which can be tensioned by pressing on a release tongue 11. If the tension exceeds a limit value, the previously held movable element 12 is displaced relative to the base body 13 by the relaxing actuating spring 20. If the pressure on the release tongue 11 is released again, the movable element 12 can move back into its original position once the tension built up by the spring element falls below a limit value.

[0029] In the exemplary embodiment, the release tongue 11 interacts with the actuating projection 19. During the first bolt extension, the actuating projection 19 moves towards the release tongue 11 and acts upon it in such a way that the actuating spring 20 is tensioned and the tension limit is exceeded, causing the movable element 12 to spring forward relative to the base body 13. Figure 5The movable element 12 is shown after this forward movement.

[0030] When moving the bar from the one in the Figure 5 the first preliminary position shown in the Figure 6 In the second preliminary position shown, the actuating projection 19 moves away from the release tongue 11, which results in the actuating spring 20 relaxing until the movable element 12 springs back.

[0031] The motion transmission element 5 is thus able to transmit a continuous rotary movement of the locking element 16 or a key either in the opening direction or in the closing direction to a back-and-forth movement of the movable element or the trigger 4.

[0032] The energy converter 2 is located in an energy converter housing 25, which may also contain a radio module with an antenna. The antenna may be located in an extension 27 that engages the window 26. The antenna can generate a radio signal that transmits the lock status data to a central receiving unit. For further details of the lock's operation, reference is made to the disclosure in DE 10 2020 103 323 A1, which is incorporated in its entirety into the disclosure of this application.

[0033] The Figures 11 to 16 Figure 2 shows a second embodiment of the invention in which the bolt 3 can only be pre-locked in one turn. This could, for example, be a toilet lock.

[0034] The lock has a tumbler 15 which can be moved vertically upwards by rotating the locking element 16. This tensions a tumbler spring 17, which may be a torsion spring. The locking element 16 engages in a rebate recess of the bolt to move the bolt from the Figure 13 presented retrospective position on the in the Figure 14 depicted intermediate position up to the point in the Figure 15 to conclude the position shown.

[0035] The locking device 15 has an actuating section 18, which in the exemplary embodiment is formed by a lug. This actuating section 18 functions analogously to the actuating section 9 of the first exemplary embodiment. If the locking device 15 is lifted in a first phase of the rotary movement of the locking element 16, the actuating section 18 acts on the edge 4" of the free end 4' of the release 4. The release 4 is thereby actuated by the Figure 13depicted position in the Figure 14 The position shown is shifted. On the way there, the release tongue 11 is actuated and the actuating spring 20 is tensioned in such a way that the movable element 12 can shift relative to the base body 13.

[0036] Is the locking element 16 removed from the one in the Figure 14 the intermediate position shown continues into the Figure 15 If the depicted end position is moved further, the locking pin 15 is moved back by the locking pin spring 17. Simultaneously, the release 4 is moved back to its initial position by the spring element 14, allowing the actuating spring 20 of the energy converter 2 to relax. Simultaneously, the movable element 12 is moved back.

[0037] The locking pin 15 forms a motion transmission element with which a continuous rotary movement of the locking element 16 or a key is transferred into a back-and-forth movement of the movable element 12 or the trigger 4.

[0038] The Figures 17 and 18Figure 1 shows a lock case with a lock base 22 and a lock top 23, the lock top 23 having a recess 24 through which an assembly 25 can be inserted into the lock case. In the exemplary embodiment, the assembly 25 is the energy converter housing 25, in which the energy converter 2, a radio module (not shown), and an antenna (also not shown) are arranged. The radio module can be operated with the electrical power generated by the energy converter 2, for example, if the energy pulse generated by the energy converter 2 is temporarily stored in a capacitor or similar energy storage device. A radio signal containing locking status data can be transmitted via the antenna, which is preferably arranged in the extension 27.

[0039] The energy converter housing 25 is preferably made of plastic and forms a cover 28 which, when assembled, closes the recess 24. On the side opposite the cover 28, the energy converter housing 25 has a projection 31 which, when assembled, fits into a window 29 in the base 22. Next to this window 29, one or more mounting openings 30 can be arranged through which mounting screws can be inserted to fasten the energy converter housing 25 to the housing 1. Figure 18 indicates how the energy converter housing 25 can be inserted into the housing opening by means of a rotational movement along the arrow.

[0040] It is considered advantageous if the energy converter housing has all the elements required for the radio transmission of a locking signal. The energy converter housing 25 has a mechanical interface in the form of the release tongue 11 of the energy converter 2, which, when actuated, results in the transmission of a radio signal. A [missing information] in the Figure 17 The lock shown, which is not equipped with the energy converter housing 25, can be used as a purely mechanical lock and can be upgraded to a radio lock by simply inserting a plastic part in the form of the assembly 25. For this purpose, it is advantageous if the retrofittable assembly 25 has only a mechanical interface, in particular in the form of a trigger tongue 11 of an energy converter 2, in order to send a radio signal by actuating it.

[0041] The Figures 19 to 21show the assembly 25, which consists of an energy converter housing 35, which contains the actual energy converter 2, and an antenna housing formed by the extension 27, which has the antenna.

[0042] The extension 27 is a hollow plastic cap which may contain the antenna (not shown) within its cavity. Arms 39 project from the edge of the cap. The arms are arranged on the two narrow sides of the extension 27 and have retaining elements 38 at their free ends. The retaining elements 38 form hooks pointing away from each other.

[0043] One side of the energy converter housing 35 facing the strike plate 21 has two slots connecting the two broad sides of the energy converter housing 35. These slots run transversely to the direction of extension of the strike plate 21 and form guide openings 36. The guide openings 36 open into a recess 40, which forms a rear guide flank 37 extending along the edge of the guide opening 36.

[0044] The arms 39 each extend through one of the two guide openings 36. The retaining elements 38 each engage behind one of the two guide flanks 37, so that the antenna housing formed by the extension 27 is displaceable in a direction transverse to the extension direction of the sleeve 21. When the extension 27 is displaced relative to the energy converter housing 35, the arms 39 move within the guide openings 36.

[0045] The Figures 22 to 26The figures show the different phases of removing a component 25 from the lock housing. Inserting the component 25 into the lock housing is carried out in reverse order.

[0046] Starting from the in Figure 26 In the fully shown removal position of assembly 25 from the lock housing, assembly 25 is removed in the opposite direction of the arrow. Figure 26 through window 24 into the one in the Figure 25 The assembly 25 is brought into the position shown, in which the extension 27 partially engages in the window 26. Contrary to the position shown in the Figure 25 The arrow shown is swivelled until it is in the Figure 24 The position shown is reached, in which the plate-shaped cover 28 extends parallel to the recess 24. In the next step, the assembly 25 is moved in the opposite direction to that shown in the Figure 24 The arrow shown is moved in the direction of the sleeve 21 until the one in the Figure 23The position shown is reached, in which the extension 27 forming the antenna housing is completely inserted into the window 26. Subsequently, the energy converter housing 35 is positioned opposite the extension 27, contrary to the position shown in the Figure 23 The arrow shown is moved until the lower extension 31 has entered the recess 29 of the lock base 2. Then the assembly 25 is in the Figure 22 The assembly 25 can then be permanently fastened to the lock base 22 using fastening screws that engage in threaded bores 41 of the energy converter housing 35 and pass through the fastening openings 30.
