Description

Closure for closing a door,

in particular a device door

The invention relates to a closure for closing a door, in particular a device door, with a lockable on a latching structure of a first closure element second closure element which is relatiwerdrehbar for unlocking relative to the first closure element, and with at least one relative to the second closure element movably arranged lever bearing, from a release position, in which it leverages the lock on the latching structure as a result of a Relatiwerdrehung, in a Locking position can be transferred, in which the locking is maintained at the locking structure in a Relatiwerdrehung.

Such door locks are used for closing a variety of devices such as cooking appliances, hot equipment, refrigerators, refrigerators, etc. and usually consist of two closure elements, of which a closure element with the door leaf of the door and a second closure element is connected to the frame of the appliance door or the device housing ,

A closure is known from EP 1 111 175 A1, in which the closure element connected to the door leaf is designed as a resilient strap which can be locked to a latching structure of a closure element fixed to the housing, designed as a locking pin. When the door is closed, the two closure elements are acted upon via a provided between the door leaf and the door frame, the interior of the device sealing rubber-elastic seal with a closing force. To release the lock and thus to open the door, the two closure elements are rotated by an operating handle relative to each other. Although such closures have proven successful in the past, as a rule they do not permit access control via which the closure can be locked against unlocking in certain situations, for example while automated cleaning processes take place inside the devices, so that the door can be locked in such a manner Situa ^¬ tions can not be opened.

From DE 10 2009 016 812 A1 a similar door lock with access control is known. In order to prevent opening of the door in certain situations, a sleeve-shaped link is rotatably mounted on the peg-shaped closure element. The scenery has in the area of the locking structure after radially outwardly facing, eccentric flank, so that can be increased by turning the backdrop of the detent structure formed by the locking structure for the purpose of access control, if necessary. After the rotation of the slide, a loosening of the bow-shaped closure element is then no longer possible even when the handle is actuated due to the rear grip extending over a larger angular range. A disadvantage of this type of access control has been found that this has a structurally comparatively complex construction. In addition, the flank of the gate is arranged in the region of the latching structure between the two closure elements, which are braced against each other when the door is closed via a rubber-elastic door seal. For each rotational movement of the gate, it is therefore necessary to overcome the corresponding closing force, which is why comparatively strong drives must be used to rotate the scenery.

Another closure with access control is known from DE 10 2009 014 233 A1. This is provided for the purpose of access control between a release position and a blocking position back and forth movably arranged lever bearing. In normal operation, the lever bearing is in the release position, in which the lever bearing, as a result of a relative rotation of the two closure elements, leveres the closure element formed as a spring clip against the force of a spring out of the latching structure of the other closure element. In this way, the lock is released by operating the arranged on the door leaf operating handle and the door can be opened. For the purpose of access control, the lever bearing from the release position is movable into a blocking position, in which this does not lever the spring clip out of the detent structure even when the actuating handle is actuated. The lever bearing is integrally formed on the housing-fixed closure pin in the manner of a radial extension. To the Moving the lever bearing, the closure pin is rotatably mounted on the housing of the device via a drive provided for this purpose. If, for example, access to the interior of the device is blocked on the basis of a cleaning process in progress, the closure pin is moved via the drive and with this the lever bearing relative to the spring clip into a position in which the spring clip no longer actuates the actuating handle is levered out of the locking structure.

In the case of this closure, too, it has proven to be disadvantageous that the lifting bearing is arranged integrally on the housing-mounted closure element for levering the resilient closure element and, to that extent, for movement of the lever bearing, the first closure element must be moved against the closing force applied between the two closure elements. With this closure, therefore, a comparatively strong drive is required for rotating the peg-shaped closure element.

It is an object of the present invention to provide a lock with access control that is simple in design and in which drives of lower power can also be used.

This object is achieved in a closure of the type mentioned above gel ö, that the lever bearing is also arranged movable relative to the first closure element. Due to the relatively movable arrangement of the lever bearing relative to both closure elements, this can be easily moved back and forth between the release and the blocking position and it can be used for the purpose of access control and drives lower power. It is not necessary, one of the closure elements or the lever bearing against the to move between the closing elements applied closing force. The result is a structurally simple structure with a little power requiring drive mechanism. A structurally advantageous development of the invention provides that the lever bearing is movable via an actuating element between the release position and the blocking position, wherein it is particularly advantageous in this context in a further embodiment of the invention, when the actuating element is driven by a motor, in particular by an electric motor. The actuation element can be guided into the region of the closure that is visible when the door is open and the drive of the actuation element inside the device housing can be arranged protected against contamination, splash water, etc. The lever bearing may be provided directly to the actuating element according to a structurally simple design, for example, the actuating element may be an axially movable rod whose lateral surface forms the lever bearing for Aushebeln the lock.

In a development of the invention, it is further proposed that the lever bearing is arranged on a pivoting element which can be pivoted over the actuating element. Through the interposition of at least one pivoting element, the actuating element can be arranged at a greater distance from the two closure elements and the lever bearing can be moved via the pivoting element into its release or blocking position. In this context, a structurally advantageous development provides that the pivoting element via the actuating element in the release position can be pressed and locked in this. The actuator comes in such a configuration to a dual function. On the one hand, the actuating element is designed as a kind of pushing element in such a way that arranged on the pivot member lever bearing is movable by applying a compressive force in its release position. On the other hand, the actuating element acts as a kind of holding element of the lever bearing in its release position. The actuating element can be designed such that it receives the forces acting on the lever bearing during a relative rotation of the closure elements without the lever bearing being moved out of its release position. In that regard, the actuating element forms a pivotal blockage of the pivoting element in the release position of the lever bearing. A further embodiment provides that the pivoting element is freely pivotable after moving back the actuating element. After retraction of the actuating element, the pivoting element can swing back in a simple manner due to the freely pivotable training and spend the lever bearing in its locked position. In this context, it is furthermore of advantage if the pivoting element is designed in such a way that, after removal of the actuating element, it moves in a self-weight-actuated manner into the locking position.

According to a structurally advantageous development of the pivoting element, it is proposed that the pivoting element is designed as a pivoting pawl, by means of which a change in direction of the direction of movement predetermined via the actuating element can be achieved. Advantageously, it may be an angularly formed pivoting pawl, whose legs are angled relative to each other and enclose the pivot axis of the pivoting element in an intermediate region. In this context, it is also advantageous if the pivoting element is designed and arranged in such a way that the leg cooperating with the actuating element extends substantially vertically in the release position and the other leg in the opposite direction runs angled. Due to the vertical alignment the cooperating with the actuator leg can achieve a favorable support of the lever bearing in the release position. Due to the contrast, angled course of the other leg, the pivot member assumes an unstable position when removing the actuating element. This results in a tilting moment due to the weight of the angled limb, which leads to a self-weight-initiated pivoting back of the lever bearing in its locked position.

To create a double Entriegelungsmöglichkeit, it may be advantageous in this context, when the pivoting element as a double

Pivot with trained on both sides of the lever bearing lever bearings is formed. The two-sided arrangement of two lever bearings elatiwerdrehungen the two closure elements in both directions, so both left and right turns, for levering the second locking element via the respective lever bearings can be used.

With regard to a compact construction, requiring little parts construction is proposed in a further embodiment that the pivot member is pivotally mounted on the first closure element. The first closure element can be used as a pivot bearing of the pivoting element.

A further embodiment provides that the pivot axis of

Swivel element parallel to the direction of the latching structure in particular horizontally extends. In a constructive embodiment, it is further proposed that the pivoting element is arranged on a side surface of the first closure element. An alternative embodiment provides that extends the pivot axis of the pivot member transversely to the direction of the latching structure in particular vertically. In such an embodiment, the pivoting element may be arranged on a lower or upper side of the closure element.

In an alternative embodiment, it is proposed that the lever bearing is arranged on a sliding element which can be displaced over the actuating element. Also by the interposition of a push element, the actuating element can be arranged at a greater distance to the two closure elements and the lever bearing can be moved via the push element in its release or blocking position.

In this context, it is further proposed that the thrust element via the actuating element in the release position can be pressed and locked in this. About the actuating element thrust element and arranged on this lever bearing is movable by applying a compressive force in its release position. In addition, the actuating element holds the lever bearing in its release position. A structurally advantageous embodiment of the thrust element provides that the thrust element is biased by a spring in the direction of the locking position of the lever bearing. The spring may be arranged so that it spins when moving the thrust element in the release position and moves the thrust element after retraction of the actuating element automatically in its blocking position.

An alternative embodiment provides that the actuating element is connected to the thrust element pressure and zuggekoppelt. About the pressure coupling, the thrust element can be pushed into the release position. About the traction coupling, the thrust element can be taken during retraction of the thrust element and spent in this way, the lever bearing in the locked position. In constructive development, it is further proposed that the thrust element is arranged to be axially movable on the first closure element. The first closure element thus also serves as a receptacle of the push element, so that no separate receptacle is required and results in a small number of parts.

In this context, it is for a defined movement advantageous if the movements of the thrust element are guided over an axial guide. As a guide, for example, serve a bolt / slot guide. It can be provided in particular that the bolt on the first closure element and the slot is arranged on the other hand movable on the thrust element.

In order to provide a double unlocking possibility, it can be provided according to a further embodiment that the thrust element in each case has a lever bearing on both sides of the first locking element.

Due to the two-sided arrangement of lever bearings relative movements of the closure elements in both directions, so both left and right turns, for levering the second closure element via the respective lever bearings can be used.

With regard to a user-friendly construction, it is proposed in a further embodiment that the second closure element is rotatable via an actuating handle and the first closure element is designed to be stationary. The operating handle may be on a pivoting actuating lever be arranged, which is deflected in a predetermined angular range of for example 45 ° from a preferably vertical index position to both sides. In this context, it is further proposed that the actuating handle is acted upon by a spring force such that it tends to zurückzuschwenken always in its index position.

Furthermore, it is proposed that the second closing element is designed as a locking pin and the actuating element extends parallel to the axis of the locking pin.

Finally, with regard to a design which permits automatic unlocking of the lock, it is proposed that the lever bearing can be moved from the release position into an open position in which the lock on the latching structure is levered out independently of the rotational position of the locking elements. By moving the lever bearing in its open position, the door is automatically opened. About the lever bearing, the second closure element is raised so far that the lock on the latching structure is released and the door under the influence of applied over the door seal closing force jumps open at least a gap. A transfer of the lever bearing in its open position can be done in particular in the context of cooking or baking operations when reaching a preset time, so that the door opens, for example, after a preset time of fifteen minutes without the operator monitor these times themselves and the device by hand must open.

Further details and advantages of a closure according to the invention will be explained below with reference to the accompanying drawings of exemplary embodiments. Show: FIGS. 1 to 3 an embodiment of a closure in a first position, wherein the lever bearing is arranged in its release position,

FIG. 26 shows a further view of the closure according to FIG. 25. FIG.

1 shows the closure 1 of a door, for example the door of a hot appliance used in the kitchen area, in the locked state. The closure 1 has as essential components at least one first closure element 2 and at least one second closure element 3, which can be locked together by means of at least one latching structure 4 arranged on the first locking element 2.

Details of the device or arranged on this door are not shown in the figures for reasons of clarity.

The individual components of the closure 1 are arranged in the exemplary embodiments shown in the figures such that the first closure element 2 is fixed to the housing on a door frame or the device housing. The second closure element 3 is arranged on the door leaf and can be moved following the movements of the door leaf when opening or closing the door with respect to the stationary first closure element 2. Alternatively, however, it would also be conceivable to arrange the first locking element 2 on the door leaf and the second locking element 3 on the housing. As can be seen in the illustration in particular in Fig. 3, the door-side closure element 3 is provided in the manner of a spring-loaded bracket with two legs 3.1, 3.2 and a transversely to the legs 3.1, 3.2 extending locking portion 3.3, which is designed in the manner of a transverse pin. In order to reduce the friction when locking the first closure element 2 with the second closure element 3, the locking region 3.3 has a roller rotatably mounted thereon, whereby friction-related signs of wear on the two closure elements 2, 3 can be reduced. The closure element 3 is connected by a total of frame-shaped geometry and rotationally coupled to a pivotable actuating handle 20, which is accessible from the outside of the door to be locked. When the handle 20 is deflected, the closure element 3 therefore follows its rotational movements and is rotated relative to the first closure element 2. The second closure element 3 is pivotally coupled to the handle 20 within the handle 20 in the direction indicated in FIG. 2 by the directional arrow there against the force of a return spring 11. The force of the return spring 11 is directed such that the closure element 3 tends to always assume a substantially horizontal position. The first closure element 2 is designed in the manner of an elongate locking pin and extends in the direction of the door-side closure element 3. The closure element 2 is fixed by pin-shaped geometry and a threaded portion 2.1 in an opening of the device housing 21, see. in particular Fig. 7. In the direction of the door or the second closure element 3, the closure element 2 has a chamfer 2.2 and two formed in the manner of undercuts locking structures 4, 6, to which the locking portion 3.3 of the second closure element 3 can be locked. Hereinafter, first, the operations of locking the second locking member 3 on the first locking member 2 will be explained, before the unlocking operation and details of the lever bearing 5 will be explained.

When locking, the door leaf and with this the second closure element 3 approaches the fixed closure element 2. The closure element 3 is initially in a substantially horizontal position until it hits the free end of the first closure element 2, which is arranged approximately at the same height and designed as a locking pin. The closure element 3 arrives with its locking region 3.3 with the bevel 2.2 of the first closure element 2 in abutment, which acts as a kind of lifting slope on further closing of the door leaf. As a result, the roll provided in the locking area 3.3 of the second closure element 2 begins to roll on the chamfer 2.2 of the first closure element 3 and the second closure element 3 begins to swing upwards out of its horizontal position, counter to the force of the spring 11 provided on the actuating grip 20. In a next step, the locking region 3.3 of the second closure element 3 enters the front latching structure 6 of the first closure element 2. The closure element 3 springs under the influence of the spring 11 down into the latching structure 6 before it then hits on further closing of the door leaf on a second chamfer 2.3, in turn raised over this and finally locked under spring force in the latching structure 4. Arrived in this position, the door is closed and the device can be used for example for cooking food. In order to be able to release the lock produced in this way between the closure elements 2, 3 by hand, it is necessary that the closure elements 2, 3 are rotated relative to each other. In the exemplary embodiments, the second closure element 2 is pivoted by actuation of the handle 20 relative to the stationary first closure element 3, whereby the locking region 3.3 is pivoted relative to the first closure element 2 on the circumference thereof also relative to the detent structures 4, 6. The handle 20 is designed for this purpose in an angular range of 45 °, starting from a substantially vertical index position to the right or left pivot.

When the handle 20 pivots to the left, the locking region 3.3 of the second closure element 3 pivoted to the right strikes the lever bearing 5 arranged laterally on the first closure element 3. The lever bearing 5 is in its release position, so that the locking region 3.3 of the second closure element 3 originates from the in the Fign. 1 to 3 illustrated position is levered over the lever bearing 5 in a kind of laterally offset tilting movement in the position shown in Figures 4 to 6, in which the closure element 3 guided by retraction of the door leaf on the latching structure 4 away and in this way the lock on the latching structure 4 can be solved.

The lever bearing 5 forms in its release position a kind of tilting edge, which ensures that the closure element 3 does not rotate about the axis of rotation of the handle 20, but is levered in a kind of tilting movement over the laterally opposite the axis of rotation of the handle 20 arranged lever bearing 5. When levering out the closure element 3 deviates against the force of the spring 11 upwards, whereby the Drehabstand between the two closure elements 2, 3 increases and the undercut of the latching structure 4 über-. can be sore. By pulling on the door handle 20, the locking area 3.3 of the first closing element 2 slides over the undercut 4. In the next step, the locking area 3.3 hits the latching structure 6 forming an intermediate locking stage and locks again. The interlocking serves to initially not completely open the door, but only to create a defined opening gap, for example, hot fumes controlled to escape from the device can. In order to release the interlocking, the handle 20 can be pivoted in the opposite direction of rotation, that is to the right, after which it is then guided over a lateral recess 6.1 provided on the second latching structure 6 and the latch as a whole can be released and the door can be completely opened, see. in particular FIG. 4.

In order to prevent access to the interior of the device in certain situations, for example for security reasons, the lever bearing 5 for access control from the rotational range of the two closure elements 21, 3 removably formed. For this purpose, the lever bearing 5 is arranged so as to be freely movable relative to both closing elements 2, 3 clamped against one another when the door is closed.

After removal of the lever bearing 5, a rotational movement of the second closure element 3 does not lead to a change in distance of the two closure elements 2, 3, so that the second closure element 3 does not pass over the undercut of the latching structure 4 of the second closure element 3 and thus the lock can be solved between the two closure elements, cf. in particular Fign. 9 to 14. For in contrast to the latching structure 6, the latching structure 4 is formed such that the rotational movements of the closure element 3 is not sufficient to release the locking area 3.3 laterally from the latching structure 4. To release the locking formed in the latching structure 4, it is necessary that the locking area 3.3 is lifted from the latching structure 4.

In order to move the lever bearing 5 between the release position and the blocking position, a motor-driven actuating element 7 is provided. The motor drive is not shown in the figures, however, can be dimensioned relatively small due to the easy-going, little force-requiring mobility of the lever 5, whereby a structurally favorable, economically advantageous construction can be realized.

The lever bearing 5 can be formed in a structurally simple manner directly from the actuating element 7 or by an additional element which is moved by actuation of the actuating element 7. In the embodiments according to FIGS. 1 to 16, 23 and 24, the additional element is formed by a pivotable about the actuating element 7 pivoting element 8. In the embodiment according to FIGS. 17 to 22, the additional element is formed by a sliding over the actuating element 7 thrust element 9, which will be discussed in detail below.

As particularly the illustrations in Figs. 7 and 8 can be seen, the pivoting element 8 is formed in the manner of a freely rotatable pivoting pawl. The pivoting element 8 has two limbs 8.1, 8.2 which run at an angle to one another and a pivot axis S arranged between the limbs 8.1, 8.2. In the release position of the lever bearing 5 shown in FIG. 7, the leg 8.1 interacting with the actuating element 7 assumes a substantially vertical position, in which it extends over the rear side on the leg 8.1 or on a pressure element provided on the latter. piece 12 adjacent actuator 7 is locked. The leg 8.2 extends at an angle to the leg 8.1 obliquely upwards and forms with its top the leverage required for levering out the lever bearing. 5

The pivoting element 8 is articulated with its substantially horizontally oriented pivot axis S pivotally mounted on one side of the peg-shaped closure element 2, so that the lever bearing 5 from the release position shown in Fig. 7, in which the lever bearing 5 in the region of the latching structure 4 is arranged , In a blocking position is movable, in which the lever bearing 5 is spaced from the latching structure 4 down.

To transfer the pivot bearing 5 into the locking position, the rod-shaped actuating element 7 is retracted in the direction of the housing. Hereupon, the pivoting element 8 assumes an unstable position and starts, in a self-weight-actuated manner, into the position shown in FIGS. To pivot 15 and 16 illustrated blocking position. When Relatiwerdrehhen the closure member 3 relative to the peg-shaped second closure element 2 of the locking portion 3.3 of the second closure element 3 does not come into contact with the lever bearing 5, so that it does not tilt over the lever bearing 5 and can be lifted out of the latching structure 4. In this position, the closure 1 is secured against unlocking, for example in the context of ongoing cleaning operations inside the device. FIGS. 23 and 24 show an embodiment of the swiveling element 8, in which the swiveling element 8 is arranged pivotably on the first closure element 2 via an axis S which extends essentially vertically. In the embodiment according to FIGS. 23 and 24, the pivoting element 8 is arranged on the underside of the closure element 2 and consists of a Leg 8.3 and a provided on this, extending into the region of the top of the closure element 2 increase 8.4. The increase 8.4 forms at the top of the actual lever bearing 5, which is shown in Fig. 23 in its release position and in Fig. 24 in its locked position. Alternatively, it would also be conceivable to arrange a pivoting element 8 on the upper side of the closure element 2. It would also be conceivable to design the pivoting element 8 such that two horizontal legs are provided, of which a leg provided below the closure element 2 cooperates with the actuating element 7 and a leg provided above closure element 2 forms the actual lever bearing 5.

An alternative embodiment of the actuated via the actuator 7, additional element is shown in Figs. 17 to 22 shown. In this embodiment, the additional element is not formed by a pivoting element but by a pusher element 9 which, via the actuating element 7, moves from its blocking position into the position shown in FIGS. 17 to 19 shown release position is movable. The displacement of the thrust element 9 in the direction of its release position takes place against the force of an exciting spring, which relaxes upon retraction of the actuating element 7 and in this way the thrust element 9 moves automatically back into its blocking position.

The pusher 9 is slidably mounted on the first locking element 2, wherein the movements of the pusher 9 are guided via an axial guide 10, which is formed by a bolt / slot guide, in which a fixed bolt 10.1 in a provided on the pusher 9 slot 10.2 engages, cf. Fig. 22.

In contrast to the first embodiment, in which the lever bearing 5 is arranged on a pivoting element 8, the pushing element 9 forms a double tes lever bearing with two arranged on both sides of the first closure element 2 lever bearings 5, see. In that regard, both left and right turns lead to a levering out of the locking portion 3.3 of the second locking element 3 from the latching structure 4. However, such a training as a double lever bearing is also conceivable in the first embodiment by a in the manner of Double pawl formed pivoting element 8 is used with arranged on both sides of the closure element 2 lever bearings. As the illustration in FIGS. 25 and 26 shows, the lever bearing 5 can not only be moved back and forth between a locking position and a release position. The illustration based on the embodiment according to FIGS. 1 to 16 shows that the lever bearing 5 is also in an open position

can be converted, in which the latching structure 4 and the second Verschlussele- element 3 are unlocked even without actuation of the actuating handle 20. The closure element 3 is raised via the lever bearing 5 in a position above the latching structure 4, so that the door jumps over the applied from the door seal on the two closure elements 2, 3 in the open position closing force with reaching the open position automatically. The open position can be used, for example, in timer-controlled baking operations as automatic opening for timely termination of the baking process. Also in the embodiment with a thrust element 9, the lever bearing 5 can be transferred into such an open position. For this purpose, it is conceivable, for example, to provide a ramp-shaped edge on the upper side of the thrust element 9.

The closure 1 described above is characterized by a comparatively simple structure allowing access control. Due to the double mobility of the lever bearing 5 both with respect to the first closure element 2 as well as the second closure element 3, the lever bearing with little effort between its release position and its blocking position are moved back and forth, so that can be used for the purpose of access control comparatively small-sized drives. The lever bearing 5 can be arranged in such a way that it can be moved away from a load path generated via the closing force of the door seal and over the first and second closure element 2, 3, resulting in a smooth movability.

In addition, since the actuating element 7 has a comparatively large distance in relation to the region of the latching structure 4 which is often difficult to access from outside, the latch can also be released manually in emergency situations, for example in situations in which the drive of the actuating element 7 has failed or the latter Power supply is interrupted. For this purpose, a pointed object can be introduced laterally into the region of the actuating element 7 and the pressure applied to the pivoting element 8 or the thrust element 9, the lever bearing 5 spent in the release position and the door can be opened.
