The lock (1) comprises a detent pawl (14), which can lock a locking element (9), which is permanently connected to a compartment door (2), in the lock such that the compartment door (2) can be held in closed position. The lock further has a first electric drive element (17) which transitions the detent pawl (14) from the locking position to a release position upon the applying of electrical power, such that the compartment door (2) can be opened. The lock (1) further comprises a security device (32), which prevents an automatic reset of the detent pawl (14) from the release position to the locking position when the lock (1) is in an unpowered state or the automatic storage machine is in an unpowered state, and an unintentional, accidental or improper locking of a compartment door can thus be avoided. In order to properly lock a compartment door, the security device (32) of the lock (1) comprises a second electric drive element, by means of which the detent pawl (14) can be transitioned back to the locking position thereof upon the applying of electrical power to said second electric drive element during closing of the compartment door (2).

Description
(1) For a better understanding of the invention the latter is explained in more detail with reference to the following Figures.

(7) First of all, it should be noted that in the variously described exemplary embodiments the same parts have been given the same reference numerals and the same component names, whereby the disclosures contained throughout the entire description can be applied to the same parts with the same reference numerals and same component names. Also details relating to position used in the description, such as e.g. top, bottom, side etc. relate to the currently described and represented figure and in case of a change in position should be adjusted to the new position.
(8)
(9) The lock 1 has a housing 3 that is as stable as possible. An extension of the housing 3 can run parallel to the depth direction of a compartment according to arrow 4 in
(10) For example, the base part 5 has an angular deflection 6 which forms an end wall plate 7 of the housing 3. In said end wall plate 7 an opening 8 is formed which allows the insertion of a locking element 9 or a corresponding locking bolt into the housing 3 of the lock 1. Said locking element 9, which can be shaped for example to be hook-like, bracket-like or eyelet-like, or can be formed by a locking bolt with undercuts or with cross-sectional widenings, is preferably connected via a mounting plate 10 as rigidly as possible and in a tear-proof manner to a corresponding compartment door 2, in particular is screwed. In
(11) According to an advantageous embodiment the mounting plate 10 for the locking element 9′ can be supported in the closed and locked state of the compartment door 2 with the interconnection of at least one spacing and screw fastening means 11 for the mounting plate 10 on the compartment door 2 in a load-transmitting manner on the housing 3 of the lock 1, in particular on its end wall plate 7. Said spacing and screw fastening means 11 is preferably made in one piece, in the manner of a block, however it can also be formed for example by one or more cylinder bodies, which ensure mutual support between the compartment door 2 or between the mounting plate 10 for the locking element 9 or 9′ and the housing 3 of the lock 1. This prevents the locking element 9 or 9′ in case of impact or pressure on the compartment door 2 from penetrating into the housing 3 further than permitted, whereby damage to the lock mechanism or the lock electronics can be prevented in a simple manner.
(12) The described lock mechanism is designed to be particularly simple and at the same time to be relatively secure from manipulation. Inside the housing 3 of the lock 1 according to the embodiment of
(13) The coupling member 12 designed preferably as a rotary latch 13 is mounted rotatably about an axle 15 which runs perpendicular to the insertion direction of the locking element 9 into the lock housing 3. The rotary movement of the rotary latch 13 about the axle 15 is thus controlled via the detent pawl 14, in particular is released or locked. In the locking position of the lock 1 shown in
(14) Preferably, the rotary latch 13—as already known—is pretensioned by means of a spring means 16 in opening direction so that the rotary latch 13 is pushed with an inactive position or release position of the detent pawl 14 into the opening position, whereby the compartment door 2 via the locking element 9′ engaging therein ring element 9′ springs open forming at least a gap width.
(15) In any case an embodiment variant of the lock construction is possible without a rotary latch 13 or without a coupling member 12, in which alternative embodiment variant the detent pawl 14 in the locked state of the compartment door 2 is in direct engagement with the locking element 9. The preferred embodiment variant of the lock 1 comprises a coupling member 12 or a rotary latch 13.
(16) The detent pawl 14 is movably coupled to a first drive element 17, preferably with a first electromagnet 18 in the manner of a tie bar magnet. In particular, the position of the detent pawl 14 can be controlled automatically by means of the first drive element 17 into a release position in which there is a rotary movement of the rotary latch 13 in the direction of its opening position.
(17) The detent pawl 14 is preferably designed as a two-armed lever, the first lever arm 19 of which represents the detent pawl 14 and works together with the coupling member 12. The second lever arm 20 is thus connected movably to the preferably electrically activatable first drive element 17. In particular, the second lever arm 20 of the detent pawl 14 is coupled movably to the linearly movable armature 21 of the first drive element 17 via a joint connection 22 such that by means of the linear downwards or upwards lift of the armature 21 the detent pawl 14 is moved from its locking position—according to
(18) Furthermore, it is possible that a balance element 24 is movably coupled to the first drive element 17 or its armature 21 via the joint connection 22. Said balance element 24 is also designed as a lever, wherein the first lever arm 25 of the balance element 24 is movably connected to the first electric drive element 17 via the joint connection 22. By means of the linear downwards and upwards lift of the armature 21 the balance element 24 performs a pivot movement about its pivot axis 26. The joint connection 22 is configured such that the detent pawl 14 and the balance element 24 are movably coupled to one another by means of the joint connection 22. To improve the manipulation security of the lock 1 advantageously the balance element 24 and the detent pawl 14 and the armature 21 of the first electric drive element 17 are balanced out at least approximately in terms of mass and/or force. The three movably coupled elements detent pawl 14, balance element 24 and armature 21 are balanced out such that on the introduction of translational or rotational pulses into the lock housing 3, such as during violent impact on the automatic storage machine or a compartment door 2, it is possible that there are no resulting movements of said three coupled elements and thus also the detent pawl 14 and thus the compartment door 2 remains reliably locked.
(19) Preferably, a first spring means 27 is designed, the spring force of pushes the detent pawl 14 continually and continuously into its locked position or locking position. Said spring means 27 can be assigned directly to the detent pawl 14, however it can also be assigned to the first drive element 17 or the armature 21. For example, the spring means 27 for the automatic transfer of the detent pawl 14 into the locked position is assigned to the balance element 24 and in the unpowered or currentless state of the first electric drive element 17 an extended position of the armature 21 relative to the drive element 17 is possible, whereby the detent pawl 14 is pushed into its locking position shown in
(20) The end face 28 of the detent pawl 14 facing the coupling member 12, in particular the rotary latch 13, bears bluntly on the coupling member 12, when the lock 1 is in the locked state shown in
(21) In addition, in
(22) As shown in
(23) The blocking element 33 can be mounted adjustably translationally and rotationally by means of a linear and pivot bearing 35a relative to the housing 3 or base part 5. A guide of the linear or pivot movement of the blocking element 33 is formed in the embodiment variant shown in
(24)
(25) As shown in
(26) Alternatively and/or in addition to restricting the pivotability of the detent pawl 14 in the direction of the locking position 36 by means of the blocking element 33, a limiting stop, which is not shown in
(27) In the locking position 36 of the detent pawl 14 shown in
(28) The detent pawl 14 is mainly pivoted actively out of the locking position 36 on the input of an unlocking signal into the lock 1 by means of the first electric drive member 17 or is moved into its release position 41 shown in
(29) The blocking element 33 shown in
(30) The means 41a for holding the blocking element 33 in the blocking position 40 can be designed in two parts and formed by a holding means 42 formed on the blocking element 33 and a holding element 43 assigned to the blocking element 33. In this case the holding means 42 and the holding element 43 with a blocking element 33 located in the blocking position 40 bear on one another in a load or force-transmitting manner and prevent a spring-force determined transfer of the blocking element 33 into the release position 38. In this way it is possible to prevent a control technology inactive or mechanically automatic locking of the compartment door in the unpowered state of the lock 1 or the higher control device. Also during the manual closing or shutting of the compartment door and the associated transfer of the coupling member 12 forced by the locking element from the opening position shown in
(31) In the embodiment shown in
(32) Alternatively, the holding pin 46 or holding bolt can also be designed as an axle, which supports a bearing sleeve or a small roller bearing not shown in the Figures, whereby the bearing surface 44 then rolls off the bearing. In this way the frictional force between the holding pin 46 and the bearing surface 44 can be reduced significantly or largely removed, whereby the required force of the electromagnet 48 for moving the blocking element 33 into the release position 38 is reduced and overall the reliability and long-term stability is improved. Likewise, in this way the wear of the holding pin 46 and the bearing surface 44 is reduced.
(33) It should be noted at this point that the embodiment of the lock 1 and security device 32 shown in
(34) For the purpose of locking the storage compartment or the lock 1 the blocking element 33 is rather movably coupled to a second electric drive element 47, preferably to a second electromagnet 48 in the manner of a tie bar magnet. In the example embodiment shown in
(35) Lastly, by means of the measures explained above, the lock 1 on shutting the compartment door can only lock the compartment door if in this time period the second electric drive element 47 is powered and the first electric drive element 17 is not powered, i.e. if the superordinate control device sends a high power, active locking signal to the lock 1.
(36) Preferably, a signal triggered by manually closing the compartment door 2, which signal is used for activating the second electric drive element 47, is supplied by a first detecting means 51. Said first detecting means 51 is used for determining whether the locking element 9′—
(37) With the existing power supply for the lock 1 or for the higher control device and with authorisation for closing the storage compartment, if the first detecting means 51 is triggered the blocking element 33 can be transferred indirectly or directly by the charging with power the second electric drive element 47 from the blocking position 40 into the release position 38, which enables the correct locking of the compartment door 2 by the lock 1.
(38) During the unlocking of the compartment door triggered by means of control technology a spring means 55 assigned to the ram element 53 can cause a linear displacement of the ram element 53 in the direction of the end wall plate 7 of the housing 3 of the lock 1. In this case the ram element 53 exits through an opening 56 in the end wall plate 7 partly out of the housing, as shown
(39) During the manual closing or shutting of the compartment door 2 the ram element 53 is moved either by the compartment door itself or—as shown in
(40) In addition, a second detecting means 57 can be designed for detecting the respective position of the detent pawl 14, in particular for detecting at least one end position of the armature 21 of the first electromagnet 18. Said second detecting means 57 can be activated by the second lever arm 58 of the balance element 24, as shown in
(41) Furthermore, the position of the blocking element 33 or the position of the second electric drive element 47, in particular the position of the armature 50 of the second electromagnet 48 can be detected by a third detecting means 59. In this case the third detecting means 59 can be actuvated by the blocking element 33, as shown in
(42) The detecting means 51, 57, 59 are preferably formed by electric switching elements, in particular by closing and/or opening contacts. The respective detecting signals or switching states of the detecting means 51, 57, 59 can be transmitted via an electric plug connection 60 to a not shown control or evaluation device.
(43)
(44) It is advantageous, if the at least one compartment door 2, 2′, 2″ can be locked by means of at least one lock 1, 1′, 1″ according to the invention only if there is a power supply to the control device 64 and the control device 64 functions correctly and according to plan.
(45) Furthermore, the control device 64 can be designed such that the at least one compartment door 2, 2′, 2″ can only be locked by means of the at least one lock 1, l′, 1″ if a person has the right or authorisation to use it or only when an authorised person makes a request to the control device 64.
(46) In principle, an automatic storage machine 61 can comprise storage compartments 62, 62′, 62″ of variable size and dimensions with respect to their height, width and depth. Likewise, the arrangement of such structurally differently designed storage compartments 62, 62′, 62″ inside the compartment arrangement 63 of the automatic storage machines 61 can be selected freely.
(47) Often for ergonomic reasons larger storage compartments 62′, 62″ are arranged in the lower section of an automatic storage machine 61. In particular, with such storage compartments 61′, 62″, because of their position in the compartment arrangement (63) or because of their compartment size, it is not possible to exclude the fact that a child may become locked inside. Therefore, the installation of locks 1, 1′, 1″ according to the invention in such storage compartments 61′, 61″ is particularly advantageous. For storage compartments 62, which because of their position or compartment size would prevent a child getting locked inside, a lock can also be used in principle which does not comprise a security device according to the invention.
(48) Lastly, in storage compartments 62′ with a particularly large height 65, the installation of more than one lock 1, 1′ may be expedient, in order to secure the corresponding compartment door 2′ sufficiently over the whole compartment height 65 from being opened by force. For this purpose the locks 1, 1′ can be arranged spaced apart from one another in the direction of the compartment height 65 of the storage compartment 62′. A measure of this kind can be used in practice for example from a compartment height 65 that is equal to or more than 50 cm.
(49) The example embodiments show possible embodiment variants of the lock 1 or the automatic storage machine 61, whereby it should be noted at this point that the invention is not restricted to the embodiment variants shown in particular, but rather various different combinations of the individual embodiment variants are also possible and this variability, due to the teaching on technical procedure, lies within the ability of a person skilled in the art in this technical field. Thus all conceivable embodiment variants, which are made possible by combining individual details of the embodiment variants shown and described, are also covered by the scope of protection.
(50) Finally, as a point of formality, it should be noted that for a better understanding of the structure of the lock 1 and the automatic storage machine 61 the latter and its components have not been represented true to scale in part and/or have been enlarged and/or reduced in size.
(51) The underlying problem addressed by the independent solutions according to the invention can be taken from the description.
(52) Mainly the individual embodiments shown in
(53) Furthermore, individual features or combinations of features of the shown and described different example embodiments can form in themselves independent solutions according to the invention.
