    [0001]
    [0002]
    [0003]
    [0004] The invention relates to a locking device for apparatuses, in particular electrics, in particular washing machines. Furthermore, the invention relates to an electrical apparatus, in particular a washing machine, as well as a use of an interlocking device.
    [0005]
    [0006] In the state of the art, interlocking devices are known, the interlocking devices being used where parts of a machine or parts of an installation are locked, eg doors or covers in a certain position.
    [0007]
    [0008] Interlocking devices are also used, for example, in washing machines.
    [0009]
    [0010] DE 10 2012 204 490 B4 discloses a pre-locking mechanism for a motor-driven interlock system and an interlock system.
    [0011]
    [0012] Furthermore, DE 603 16 237 T2 discloses a device for locking the door of a washing machine.
    [0013]
    [0014] Likewise, in document EP 1826309 B1 a door closure of a device with a rotating drum is described. In addition, document EP 0439 849 B1 shows a door interlock device with a rapid interlock and a delayed unlocking, in particular for a washing machine.
    [0015]
    [0016] The object of the invention is to provide a locking device, for example for washing machines, the locking device having to be small and having to allow a reliable locking, for example of a door or a lid.
    [0017]
    [0018] This objective is achieved by means of a locking device for devices, in particular electrics, in particular washing machines, with a linearly movable locking pin and a linearly movable pusher for the locking pin, the pusher being connected by means of a tensioning device with the interlocking pin.
    [0019]
    [0020] The invention is based on the idea that, for a locking pin, which in the locked state engages in a locking body, the pusher for the locking body is coupled exclusively with the use of a tensioning device with the locking pin. Here, both the locking pin and the pusher are linearly movable. In particular, the direction of movement of the pusher is collinear with respect to the direction of movement of the locking pin, so that the locking pin is actuated or can be actuated by the pusher.
    [0021]
    [0022] By means of the tensioning device, during the movement of the pusher by means of the tensioning device, the locking body is urged with a force, so that the locking pin moves, thus preventing a unilateral application of force or a tilt of the locking pin. . In particular, in one configuration in the locking device, only one linearly movable locking pin is provided and also preferably only one linearly movable ram for the locking pin, the ram being coupled exclusively mechanically by means of the tensioning device with the interlocking pin. Here, the tensioning device is prestressed between the pusher and the locking pin.
    [0023]
    [0024] In another embodiment of the locking device, it is advantageously provided that the tensioning device has two springs arranged in a row one after the other, whereby a spring arrangement is made in series. Thanks to the arrangement of springs in series, for example, a tilting of the locking pin is avoided.
    [0025]
    [0026] In particular, a first spring of the tensioning device and a second spring of the tensioning device are mechanically decoupled from one another. In this way it is possible that, by locking the locking pin in a standby position, in which the locking pin is not moved or does not move, the pusher moves linearly with respect to the locking pin, so a spring of the tensioning device remains under mechanical pre-tension, while the second spring loosens or is relaxed.
    [0027]
    [0028] In addition, thanks to the provision of a first spring and a second spring, also in the case of an emergency unlocking, in which the locking pin is located and maintained in a locking position, the pusher first moves, therefore, a spring remains under tension, while the second spring is relaxed. When the locking pin is subsequently released, by the mechanical pre-tensioning of the prestressed spring, the locking pin moves linearly.
    [0029]
    [0030] In particular, a stop on the pusher is provided respectively for the first spring and a stop on the pusher and on the locking pin respectively is provided on the locking pin and / or for the second spring. Here, the first spring and the second spring are arranged with respect to the longitudinal extension of the pusher one after the other or in a row in the pusher.
    [0031]
    [0032] According to another aspect, in the locking device it is provided that at least one stop body provided in the pusher, in particular a safety ring, is provided between the first spring of the tensioning device and the second spring of the tensioning device. In this way, the first spring and the second spring are arranged or can be disposed respectively on one side of the pin-shaped pusher in the stop body. In one configuration, several abutment bodies spaced apart from each other, in particular safety rings, are arranged as stops for the first spring and the second spring on the pusher, so that the first spring and the second spring are respectively arranged or prestressed between the stop body and a corresponding stop of the locking pin for the first and the second spring.
    [0033]
    [0034] In addition, a variant of the locking device is characterized in that for the first spring of the tensioning device a stop is provided on the outside or inside of the locking pin and for the second spring of the tensioning device a stop is provided on the outside or on the outside. the interior of the locking pin, the first stop for the first spring and the second stop for the second spring being disposed opposite one another.
    [0035] Likewise, the locking device is characterized in that the first spring of the tensioning device and / or the second spring of the tensioning device are respectively made as a compression spring, in particular as a helical compression spring or as a tension spring.
    [0036]
    [0037] For this purpose, it is advantageously provided that the first spring of the tensioning device, preferably made as a compression spring and / or the second spring of the tensioning device, preferably realized as a second compression spring, is so arranged in the pusher that the pusher passes through. by spring or springs. As a result, the compression springs or coil springs are arranged around the pusher.
    [0038]
    [0039] Furthermore, the interlocking device is characterized in another aspect that the pusher for the locking pin is housed at least partly in a hollow space of the locking pin. The pusher and the locking pin are housed one independently of the other and are preferably positioned one inside the other, the pusher being housed at least partly on the locking pin. By the coupling of the plunger with the locking pin, the plunger and the locking pin are mobile with respect to one another using the tensioning device.
    [0040]
    [0041] In addition, the tensioning device is preferably housed at least in part or completely in a hollow space of the locking pin.
    [0042]
    [0043] Furthermore, in the locking device it is advantageously provided that a drive, in particular a lifting drive, is provided for the linear movement of the pusher, in particular the drive, in particular the lifting drive, being carried out as a bistable lifting electroimage.
    [0044]
    [0045] In particular, the pusher for the locking pin is linearly guided on the outside or on the inside of the locking pin, the pusher and the locking pin being (linearly) movable with respect to each other.
    [0046] Furthermore, in a preferable configuration of the locking device, provision is made for a locking element, in particular a rotating one, by engaging the locking pin in a locking position of the locking pin in the locking body. For this purpose, the locking body has, for example, a recess in which the locking pin engages in the locking position of the locking body. In this way the locking body is locked or fixed in its movement. In the open state, the locking pin does not fit in the locking body or does not fit into the recess of the locking body, whereby the locking body is released.
    [0047]
    [0048] In addition, the objective is achieved by an electrical appliance, in particular a washing machine, with a lockable door and with a locking device described above for the door. To avoid repetitions, expressly refer to these explanations.
    [0049]
    [0050] Also, the objective is achieved by using an interlocking device such as that described above in an electrical appliance, in particular in a washing machine.
    [0051]
    [0052] Other characteristics of the invention will be indicated in the description of forms of realization according to the invention together with the claims and the attached drawing. The forms of realization according to the invention can fulfill individual characteristics or a combination of several characteristics.
    [0053]
    [0054] In the following, the invention will be described without limiting the general inventive idea with the help of an example of realization making reference to the drawing, referring expressly to the drawing with respect to all the details according to the invention not explained in detail in the text. Sample:
    [0055]
    [0056] Figure 1 is a cross-sectional view in schematic representation of an interlocking device in the open state.
    [0057]
    [0058] Figure 1 shows a cross-sectional view of an interlocking device 10 according to the invention, which is used for example for washing machines, in particular for industrial washing machines. Here, the locking device 10 is used, for example, for closing doors or covers for washing machines.
    [0059]
    [0060] The locking device 10 has a housing 12, in which a bistable lifting electroimage 14 is arranged as a drive for a linearly movable pusher 16. The bistable lifting electroimage 14 moves the pusher 16 in the arrangement shown in Figure 1 in a linear reciprocating movement. The pusher 16 is disposed therein inside a locking pin 18, the pusher 16 provided for actuating the locking pin 18 being housed partly in the locking pin 18.
    [0061]
    [0062] Furthermore, a first compression spring 20 and a second compression spring 22 between the pusher 16 and the locking pin 18 are disposed inside the locking pin 18. Between the first spring 20 and the second spring 22, in the pusher 16, safety rings 24, 26 are provided as stops for the springs 20, 22, which are arranged at a distance from each other in the longitudinal extension of the pusher 16. In this way, the first spring 20 between the safety ring 24 and a spring is tensioned. stop 28 on the locking pin 18, which is made on the side facing the lifting electroim 14.
    [0063]
    [0064] The second spring 22 is prestressed between the safety ring 26 in the pusher 16 and a stop 30 provided on the side facing the free end of the pusher 16 of the locking pin 18. The safety rings 24, 26 are made here as stops for the first spring 20 and the second spring 22 on the pusher 16.
    [0065]
    [0066] The first spring 20 and the second spring 22 are arranged in a row and one after the other with respect to the longitudinal extension of the pusher 16, the first spring 20 and the second spring 22 being separated mechanically from one another by the safety rings 24, 26 The first spring 20 and the second spring 22 form a tensioning device between the pusher 16 and the locking pin 18, so that by pre-tensioning the springs 20, 22 between the corresponding safety rings 24 and 26 and the stops 28 and 30 corresponding to the pin of interlock 18 the pusher 16 is attached or coupled with the locking pin 18.
    [0067]
    [0068] In addition, the locking device 10 has a rotary locking body 32 below the locking pin 18, the locking body 32 having a recess 34 for receiving the locking pin 18 in the contour, so that at the moment of the positioning of the locking body 32 for the locking of the locking body 32 the recess 34 is positioned below the free end of the locking pin 18 and the locking pin 18 is received in the recess 34. In the locking body 32 is arranged furthermore a spring 36 which engages in the locking body 32, so that, in the non-locked state, the rotary locking body 32 is rotated or rotated out of the locking position.
    [0069]
    [0070] When the locking body 32 is rotated counterclockwise, the recess 34 is positioned below the locking pin 18 for the interlock. For the interlock, current is applied to the lifting electroimage 14, so that the pusher 16 moves in a linear downward direction, the pusher 16 moving along with the locking pin 18 in the direction of the locking body 32 and its recess 34 for the locking pin 18, until the locking pin 18 engages in the recess 34, due to the engagement of the pusher 16 by the first tensioned spring 20 and the second spring 22 tensioned.
    [0071]
    [0072] In order to rotate the locking body 32 to the locking position, the locking body 32 is rotated, for example, by means of a hook or the like.
    [0073]
    [0074] When the locking body 32 is not positioned in the locking position for the locking process, as shown in Figure 1, the locking pin 18 can be passed to a standby position for the interlock, applying current to the lifting electrohandle. 14, so that the pusher 16 moves linearly (downwardly), so that the first spring 22 is kept under pre-tension, the latching pin 18 not moving. At the same time, the other spring 20 is relaxed or relaxed ( the First). To lock the locking body 32, it is rotated counterclockwise so that the locking pin 18 is passed through the prestressed spring 22 into the recess 34.
    [0075]
    [0076] In normal operation, when the locking device 10 is opened in the event of a current application to the lifting electroimage 14, the pusher 16 and the locking pin 18 move in the direction of the lifting electroimage 14, so that the pin moves as well of interlock 18 by the springs 20, 22 which strike at the same time in the locking body 32 and in the pusher 16.
    [0077]
    [0078] If, in a locking position in which the locking pin 18 engages in the recess 34 of the locking body 32, for example, the locking body 32 is rotated with an external manual force towards the locking pin 18, of In such a way that a free linear movement of this locking pin 18 is prevented, it is possible for the pusher 16 to move in the direction of the lifting electromagnet 14 by the application of current to the lifting electroimage 14, whereby a pre-tension to the spring 20 is applied. , the locking pin 18 being held or held in the locking position. At the same time, the second spring 22 is relaxed. When the clamping force 32 in the locking body 32 is reduced, the locking pin 18 is released by the pretensioned spring 20 in continuation of the locking position and moves linearly. that the locking body 32 is released. By the linear arrangement of the springs 20, 22, one after the other along the longitudinal extension of the pusher 16, it is possible to make available a small locking device 10.
    [0079]
    [0080] All the characteristics indicated, also the characteristics that are only shown in the drawings, so! as the individual characteristics that have been disclosed in combination with other characteristics, they are considered essential for the invention, both individually and in combination. The embodiments according to the invention can be fulfilled with individual characteristics or a combination of various characteristics. In the context of the invention, the characteristics that are characterized with "in particular" or "preferably" are to be understood as optional features.
