Description

Die Erfindung betrifft ein Kühl- und/oder Gefriergerät mit einem Korpus, der einen Innenraum definiert, und mit einer Tür, die eine großflächige Glasscheibe umfasst, durch die der Innenraum von der Außenseite des Geräts sichtbar ist. Die Erfindung betrifft weiterhin die Verwendung eines solchen Geräts.The invention relates to a refrigerator and / or freezer with a body that defines an interior space, and with a door that comprises a large-area glass pane through which the interior space is visible from the outside of the device. The invention also relates to the use of such a device.

Vom Lebensmitteleinzelhandel wird vor dem Hintergrund der Verkaufsförderung unter anderem gewünscht, dass Verkaufsmöbel wie beispielsweise Kühlregale optisch in den Hintergrund treten und die präsentierten Waren im Vordergrund stehen. Als Kennzahl in diesem Zusammenhang dient die sogenannte "Total Display Area", welche im Prinzip das Ausmaß beschreibt, in dem ein Kunde Einsicht in den Innenraum des Verkaufsmöbels nehmen kann. Dabei kommt im Falle von Kühlregalen mit Glastüren der vom Glas eingenommenen Fläche eine maßgebliche Bedeutung zu, da die Total Display Area in derartigen Regalen mit dem Anteil der Glasscheiben an der Gesamtfläche der Türen steigt.In the context of sales promotion, food retailers want, among other things, that sales furniture such as refrigerated shelves take a back seat and that the goods presented are in the foreground. The so-called “Total Display Area”, which in principle describes the extent to which a customer can view the interior of the sales unit, is used as a key figure in this context. In the case of refrigerated shelves with glass doors, the area occupied by the glass is of decisive importance, since the total display area in such shelves increases with the proportion of glass panes in the total area of the doors.

Im Stand der Technik ist es bekannt, Griffe am Rand oder, durch Nieten, Kleben oder Schrauben, innerhalb der Glasfläche der Glastüren derartiger Kühlregale zu montieren. Daraus ergeben sich mehrere Nachteile. Zum einen stellt der Griff ein exponiertes Bauteil dar, das bei Transport, Montage und Gebrauch beschädigt werden kann. Um dies zu vermeiden, werden Griffe für die Auslieferung nur beigelegt und müssen vor Ort montiert werden, oder es gibt eine aufwändige Verpackung, um die Griffe zu schützen. Ferner vermindern die Griffe die Total Display Area und stören optisch das Bild einer großen homogenen Glasfront.It is known in the prior art to mount handles on the edge or, by riveting, gluing or screwing, within the glass surface of the glass doors of such refrigerated shelves. This has several disadvantages. For one, the handle adjusts exposed component that can be damaged during transport, assembly and use. In order to avoid this, handles for delivery are only enclosed and must be installed on site, or there is complex packaging to protect the handles. Furthermore, the handles reduce the total display area and optically disrupt the image of a large, homogeneous glass front.

Aufgabe der Erfindung ist es, ein Kühl- und/oder Gefriergerät bereitzustellen, welches diese Nachteile des Standes der Technik überwindet.The object of the invention is to provide a refrigerator and / or freezer which overcomes these disadvantages of the prior art.

Vor diesem Hintergrund betrifft die Erfindung ein Kühl- und/oder Gefriergerät mit den Merkmalen des Anspruchs 1.Against this background, the invention relates to a refrigerator and / or freezer with the features of claim 1.

Die Tür wird erfindungsgemäß also automatisch bewegt, wenn eine davor stehende Person wie beispielsweise ein Kunde eines Lebensmittelhandels eine bestimmte Geste mit seiner Hand ausführt. Zu diesem Zweck umfasst das Gerät eine Steuereinheit, die mit dem Sensor und dem Motor verbunden ist und auf der ein entsprechender Algorithmus hinterlegt ist. Die Tür muss nicht mehr berührt oder selbständig mit Muskelkraft bewegt werden. Die Tür wird erfindungsgemäß nicht bei Erkennung irgendeiner im Bereich der Tür stattfindenden Bewegung bedient, sondern nur bei Erkennung einer bestimmten Handbewegung. So kann eine ungewollte Öffnung aufgrund, beispielsweise, eines Vorbeigehens einer Person vermieden werden.According to the invention, the door is therefore automatically moved when a person standing in front of it, such as a customer of a grocery store, performs a certain gesture with his hand. For this purpose, the device includes a control unit that is connected to the sensor and the motor and on which a corresponding algorithm is stored. The door no longer has to be touched or moved independently with muscle power. According to the invention, the door is not operated when any movement occurring in the area of the door is detected, but only when a specific hand movement is detected. In this way, an unwanted opening due to, for example, a person passing by can be avoided.

Durch die gestengesteuerte Türbewegung wird eine Maximierung der Glasfläche der Türen und mithin der Total Display Area ermöglicht. Die Glasflächen der Türen können weit an den Rand gezogen und störende Griffe vermieden werden.The gesture-controlled door movement enables the glass surface of the doors and thus the total display area to be maximized. The glass surfaces of the doors can be pulled far to the edge and annoying handles can be avoided.

Bei der Glasscheibe kann es sich um eine durchsichtige Scheibe aus Keramikglas oder Kunststoffglas handeln. Bei dem Gerät kann es sich um ein Stand- bzw. Einbaugerät mit einem nach vorne offenen Innenraum oder auch um eine Truhe mit einem nach oben offenen Innenraum handeln. Entsprechend kann es sich bei der Tür um eine frontseitige Schiebe- oder Schwenktür oder um einen deckenseitigen Schiebe- oder Klappdeckel handeln.The glass pane can be a transparent pane made of ceramic glass or plastic glass. The device can be a floor-standing or built-in device with an interior that is open to the front, or a chest with an interior that is open at the top. Accordingly, the door can be a sliding or pivoting door on the front or a sliding or hinged cover on the ceiling.

Der Motor steht mit der Steuereinheit in Verbindung und wird von dieser in Reaktion auf die Gestenerkennung der Sensorik angesteuert. Besonders geeignet sind Elektromotoren. Die Kraftübertragung kann im Falle einer Schwenktür oder Schwencklappe direkt am Türscharnier oder anhand einer einem Türschließer nachempfundenen Türbewegungsmechanik mit beispielsweise einen Kniegelenk oder einer Gleitschiene erfolgen. Im Falle einer Schiebetür oder Schiebeklappe kann die Kraftübertragung anhand eines oder mehrerer Räder oder Zugelemente erfolgen.The motor is connected to the control unit and is activated by it in response to the gesture recognition of the sensor system. Electric motors are particularly suitable. In the case of a pivoting door or pivoting flap, the force can be transmitted directly on the door hinge or using a door movement mechanism based on a door closer with, for example, a knee joint or a slide rail. In the case of a sliding door or sliding flap, the force can be transmitted using one or more wheels or tension elements.

In einer Ausführungsform ist vorgesehen, dass es sich bei der bestimmten Handbewegung um eine senkrecht oder schräg zur Ebene der Tür verlaufende Bewegung handelt. In dieser Ausführungsvariante handelt sich bei der zum Auslösen bzw. Steuern der Bewegungsautomatik der Tür notwendigen Handbewegung also um eine solche Handbewegung, die der Öffnungs- bzw. Schließbewegung für eine tatsächliche Schwenktür oder -klappe nachempfunden ist. Entsprechend kann diese Ausführungsform insbesondere bei solchen Geräten sinnvoll sein, die einen nach vorne offenen Innenraum und eine frontseitige Schwenktür umfassen. Ferner kann diese Ausführungsform bei Truhen Anwendung finden, die einen nach oben offenen Innenraum und einen Klappdeckel umfassen.In one embodiment it is provided that the specific hand movement is a movement running perpendicular or obliquely to the plane of the door. In this embodiment variant, the hand movement necessary for triggering or controlling the automatic movement of the door is a hand movement that is modeled on the opening and closing movement for an actual pivoting door or flap. Accordingly, this embodiment can be useful, in particular, for devices that have an interior space that is open to the front and a front pivoting door. Furthermore, this embodiment can be used in chests which comprise an interior space that is open at the top and a hinged lid.

In einer Ausführungsform ist vorgesehen, dass es sich bei der bestimmten Handbewegung um eine parallel oder schräg zur Ebene der Tür verlaufende horizontale Bewegung handelt. In dieser Ausführungsvariante handelt sich bei der zum Auslösen bzw. Steuern der Bewegungsautomatik der Tür notwendigen Handbewegung also um eine solche Handbewegung, die der Öffnungs- bzw. Schließbewegung für eine tatsächliche Schiebetür oder -klappe nachempfunden ist. Entsprechend kann diese Ausführungsform insbesondere bei solchen Geräten sinnvoll sein, die einen nach vorne offenen Innenraum und eine frontseitige Schiebetür umfassen. Ferner kann diese Ausführungsform bei Truhen Anwendung finden, die einen nach oben offenen Innenraum und einen Schiebedeckel umfassen.In one embodiment it is provided that the specific hand movement is a horizontal movement running parallel or obliquely to the plane of the door. In this embodiment variant, the hand movement required to trigger or control the automatic movement of the door is a hand movement that is modeled on the opening or closing movement for an actual sliding door or flap. Accordingly, this embodiment can be useful, in particular, for devices that have an interior space that is open to the front and a sliding door on the front. Furthermore, this embodiment can be used in chests which comprise an interior space open at the top and a sliding cover.

In einer Ausführungsform ist vorgesehen, dass die bestimmte Handbewegung eine bestimmte Mindestamplitude besitzen muss und/oder in einem Winkel zur Senkrechten bzw. Waagrechten verlaufen muss, der einen bestimmten Maximalwinkel nicht übersteigt, und/oder eine Geschwindigkeit innerhalb eines bestimmten Intervalls aufweisen muss und/oder in einem Abstand von der Tür vollzogen werden muss, der unterhalb eines bestimmten Maximalabstands liegt, und/oder in einem bestimmten Bereich vor der Tür vollzogen werden muss und/oder ein Mindestmaß an Homogenität besitzen muss. Die Mindestamplitude kann beispielsweise 5 cm oder 10 cm betragen. Der Maximalwinkel zur Senkrechten, im Falle einer Schwenktür oder -klappe, bzw. Waagrechten, im Falle einer Schiebetür oder -klappe, kann beispielsweise 45° oder 30° betragen, wobei als Senkrechte die senkrecht auf die Türfläche stehende Linie und als Waagrechte die parallel zur Türfläche verlaufende horizontale Linie zu verstehen ist. Ein geeignetes Geschwindigkeitsintervall kann beispielsweise mit 0,1-1 m/s und vorzugsweise mit 0,2-0,5 m/s definiert werden, was der Geschwindigkeit einer typischen Ziehbewegung entsprechen würde. Der Maximalabstand von der Tür kann beispielsweise 1 m betragen. Somit würden nur Bewegungen nahe der Tür erfasst. Als bestimmter Bereich vor der Tür kann beispielsweise ein Bereich definiert werden, der senkrecht vor der Türfläche liegt, seitlich nicht oder maximal 30 cm über die Flucht der Türfläche hinaussteht und innerhalb des Mindestabstandes liegt. Das Homogenitätskriterium kann beispielsweise erfordern, dass die Geschwindigkeit der Bewegung über die Strecke der Mindestamplitude nicht mehr als 70% oder nicht mehr als 50% um einen Mittelwert streut. Einzelne, mehrere oder alle dieser Kriterien erlauben es, ein Bewegungsmuster zu definieren, welches Öffnungsbewegung für eine tatsächliche Tür möglichst umfassend erfasst und andere Bewegungsmuster möglichst zielsicher ausschließt.In one embodiment it is provided that the certain hand movement must have a certain minimum amplitude and / or must run at an angle to the vertical or horizontal that does not exceed a certain maximum angle and / or must have a speed within a certain interval and / or must be carried out at a distance from the door that is below a certain maximum distance, and / or must be carried out in a certain area in front of the door and / or must have a minimum degree of homogeneity. The minimum amplitude can be, for example, 5 cm or 10 cm. The maximum angle to the vertical, in the case of a pivoting door or flap, or horizontal, in the case of a sliding door or flap, can for example be 45 ° or 30 °, the vertical line being perpendicular to the door surface and the horizontal line being parallel to the Horizontal line running through the door surface is to be understood. A suitable speed interval can for example be defined as 0.1-1 m / s and preferably 0.2-0.5 m / s, which would correspond to the speed of a typical pulling movement. The maximum distance from the door can be 1 m, for example. This means that only movements close to the door are recorded. As a certain area in front of the door, for example, an area can be defined that is perpendicular in front of the door surface, not to the side or a maximum of 30 cm above the line of the door surface protrudes and is within the minimum distance. The homogeneity criterion can require, for example, that the speed of the movement does not spread more than 70% or not more than 50% around a mean value over the distance of the minimum amplitude. Individual, several or all of these criteria allow a movement pattern to be defined, which records the opening movement for an actual door as comprehensively as possible and excludes other movement patterns as accurately as possible.

Erfindungsgemäß ist vorgesehen, dass das Gerät ausgebildet ist, die Tür so zu bewegen, dass die Türbewegung der Handbewegung in ihrer Richtung und in ihrer Geschwindigkeit und in ihrer Amplitude folgt. Die Türbewegung wird also so an die Handbewegung gekoppelt, wie dies auch bei einer manuellen Türöffnung der Fall wäre. Beispielsweise kann also vorgesehen sein, dass die Tür geöffnet wird, wenn die Hand senkrecht oder schräg zur Ebene der Tür von dieser weg bewegt wird, dass die Türbewegung gestoppt wird, wenn diese Bewegung beendet wird, und dass die Tür geschlossen wird, wenn die Hand senkrecht oder schräg zur Ebene der Tür zu dieser hin bewegt wird.According to the invention it is provided that the device is designed to move the door in such a way that the door movement follows the movement of the hand in its direction and in its speed and in its amplitude. The door movement is linked to the hand movement in the same way as it would be if the door were opened manually. For example, it can be provided that the door is opened when the hand is moved perpendicularly or obliquely to the plane of the door away from the latter, that the door movement is stopped when this movement is ended, and that the door is closed when the hand is moved perpendicular or obliquely to the plane of the door towards this.

In einer Ausführungsform ist vorgesehen, dass das Gerät ausgebildet ist, die Tür automatisch zu schließen, wenn anhand des Sensors ein Entfernen der Person erkannt wird und/oder wenn die Tür eine bestimmte Zeit offen gestanden ist und der Sensor keine Bewegung vor der Tür erkennt. Die Tür wird in dieser Ausführungsform also unabhängig von einer Schließbewegung des Benutzers geschlossen. Dies erhöht den Komfort und vermeidet ein unter den Gesichtspunkten der Energieeffizienz und Konstanz der Lagertemperatur ungünstiges Offenstehen der Tür nach Benutzung.In one embodiment it is provided that the device is designed to automatically close the door when the sensor detects removal of the person and / or when the door has been open for a certain time and the sensor does not detect any movement in front of the door. In this embodiment, the door is closed independently of a closing movement by the user. This increases comfort and avoids leaving the door open after use, which is unfavorable from the point of view of energy efficiency and constancy of the storage temperature.

In einer Ausführungsform ist vorgesehen, dass es sich bei dem Sensor um eine Kamera handelt, die mit einer Elektronik zur Bildauswertung gekoppelt ist. Anhand einer derartigen Lösung können Körperteile von Benutzern und deren Bewegungsabläufe gut erkannt werden. Ferner kann eine bestimmte Position des Benutzers erkannt werden. Alternativ oder ergänzend kann beispielsweise ein kapazitiver Sensor zur Anwendung kommen.In one embodiment it is provided that the sensor is a camera that is coupled to electronics for image evaluation. With the aid of such a solution, parts of the body of users and their movements can be easily recognized. Furthermore, a specific position of the user can be recognized. Alternatively or in addition, a capacitive sensor can be used, for example.

In einer Ausführungsform ist ein Sicherheitssystem vorgesehen, das eine Kollision der Tür mit einem Benutzer oder eine zu schnelle Bewegung oder zu hohe Kräfte vermeidet. Das Sicherheitssystem kann beispielsweise einzelne oder mehrere der folgenden Aspekte umfassen. Einerseits kann vorgesehen sein, dass die Tür unabhängig von einer etwaigen höheren Geschwindigkeit der Handbewegung immer nur mit einer maximalen Geschwindigkeit bewegt wird. Ferner können der Motor oder die den Motor mit der Tür verbindende Mechanik einen Gegenkraftsensor umfassen, der eine durch Kollision der Tür hervorgerufene Gegenkraft erkennt und die Bewegung temporär stoppt. Des Weiteren kann der Sensor zur Bewegungserkennung auch dazu genützt werden, ein in der Bewegungsbahn stehendes Objekt zu erkennen, sodass eine Bewegung der Tür in Richtung dieses Objekts entsprechend temporär unterbunden werden kann.In one embodiment, a safety system is provided which prevents the door from colliding with a user or from moving too quickly or from excessive forces. The security system can for example comprise one or more of the following aspects. On the one hand, it can be provided that the door is only moved at a maximum speed regardless of any higher speed of the hand movement. Furthermore, the motor or the mechanism connecting the motor to the door can comprise a counterforce sensor which detects a counterforce caused by a collision of the door and temporarily stops the movement. Furthermore, the sensor for motion detection can also be used to detect an object standing in the movement path, so that a movement of the door in the direction of this object can be temporarily prevented.

In einer Ausführungsform ist vorgesehen, dass die Front der Tür vollständig durch eine vorzugsweise rahmenlose Glasscheibe gebildet wird und/oder dass die Tür keine Griffe aufweist. In dieser Ausführungsform sind keine Elemente mehr vorhanden, welche die Sicht auf die im Innenraum befindlichen Waren behindern würden. Bei der Tür kann es sich um eine Glasplatte handeln, die im geschlossenen Zustand oben und unten an einer Dichtung des Gerätekorpus aufliegt. Die im Falle einer Schwenktür oder Schwenklappe notwendigen Türangeln können durch beispielsweise Aufstecken, Nieten, Kleben oder Schrauben an zwei gegenüberliegenden Ecken der Tür befestigt sein. Die Schiebetür oder Schiebeklappe kann an gegenüberliegenden Seiten in Führungen des Korpus aufgenommen sein.In one embodiment it is provided that the front of the door is formed completely by a preferably frameless glass pane and / or that the door has no handles. In this embodiment, there are no longer any elements that would obstruct the view of the goods located in the interior. The door can be a glass plate that, when closed, rests on a seal on the device body at the top and bottom. The hinges required in the case of a pivoting door or hinged flap can be attached to two opposite corners of the door by, for example, attaching, riveting, gluing or screwing. The sliding door or sliding flap can be accommodated on opposite sides in guides of the body.

In einer Ausführungsform ist vorgesehen, dass der Innenraum mehrere vorzugsweise nebeneinander liegende Abschnitte aufweist, denen jeweils eine eigene Tür zugeordnet ist. Bei dem erfindungsgemäßen Gerät kann es sich also um ein großes Selbstbedienungs-Kühlregal oder eine große Selbstbedienungs-Kühltruhe für den Verkaufsraum eines Lebensmittelhandels handeln, das gegebenenfalls auch mehrere Verdichter und Kältemittelkreisläufe aufweist und mehrere Temperaturzonen in sich vereint.

The device according to the invention can be used advantageously in such an application. For customer orientation, for example, a sticker or an imprint can indicate the automatic function of the door.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus dem nachfolgend anhand der Figur dargestellten Ausführungsbeispiel.Further details and advantages of the invention emerge from the exemplary embodiment shown below with reference to the figure.

Die einzige Figur zeigt ein großes Kühl- und/oder Gefriergerät 100 mit mehreren Türen 10, das zur Verwendung als Selbstbedienungs-Kühlregal in einem Verkaufsraum eines Lebensmittelhandels bestimmt ist.The single figure shows a large refrigerator and / or freezer 100 with several doors 10, which is intended for use as a self-service refrigerated shelf in a sales room of a grocery store.

Der Innenraum des Geräts 100 umfasst mehrere verbundene Abschnitte, wobei jedem Abschnitt eine eigene Tür 10 zugeordnet ist. Bei den Türen 10 handelt es sich um Schwenktüren, die an ihren jeweils rechten Seiten oben und unten Lagerzapfen 11 umfassen und damit an einer Leiste 21 des Korpus 20 befestigt sind. Die Türen umfassen jeweils eine große Glasscheibe 12, die im Wesentlichen die gesamte Türfläche einnimmt und lediglich allseitig in einen dünnen Raumen 13 eingefasst ist. Durch die Glasscheibe 12 ist der Geräteinnenraum von außen gut sichtbar. Die Türen 10 weisen keinen Türgriff auf.The interior of the device 100 comprises a plurality of connected sections, each section being assigned its own door 10. The doors 10 are pivoting doors which comprise bearing pins 11 on their respective right sides at the top and bottom and are thus fastened to a strip 21 of the body 20. The doors each include a large glass pane 12 which essentially takes up the entire door surface and is only enclosed on all sides in a thin space 13. The interior of the device is clearly visible from the outside through the glass pane 12. The doors 10 do not have a door handle.

Stattdessen weist das Gerät 100 mehrere im Korpus 20 verbaute Elektromotoren auf, wobei je ein Motor mit je einer Tür 10 über eine nicht näher dargestellte Mechanik in Verbindung steht. Die Mechanik ist so ausgebildet, dass die Öffnungs- und Schließbewegung der Tür 10 anhand des Motors gesteuert werden kann. Ferner weist das Gerät mehrere im Korpus 20 verbaute Kameras auf, wobei je eine Kamera je einer Tür 10 zugeordnet ist und der Erfassungsbereich jeder Kamera den Bereich vor der dazugehörigen Tür 10 umfasst. Das Gerät 100 weist eine Steuereinheit auf, die mit den Kameras und den Motoren verbunden ist. Auf der Steuereinheit ist eine Bilderkennungssoftware hinterlegt, anhand welcher die Kamerabilder auf Bewegungen von vor den Türen 10 stehenden Personen hin ausgewertet werden können.Instead, the device 100 has a plurality of electric motors built into the body 20, one motor each being connected to a door 10 via a mechanism not shown in detail. The mechanism is designed so that the opening and closing movement of the door 10 can be controlled using the motor. Furthermore, the device has several cameras built into the body 20, one camera being assigned to each door 10 and the detection area of each camera including the area in front of the associated door 10. The device 100 has a control unit which is connected to the cameras and the motors. Image recognition software is stored on the control unit, with the aid of which the camera images can be evaluated for movements of people standing in front of the doors 10.

Ferner ist auf der Steuereinheit ein Algorithmus hinterlegt, um anhand des zugehörigen Motors eine bestimmte Tür 10 zu bewegen, wenn anhand der Kamera und Bilderkennungssoftware eine senkrecht oder schräg zur Ebene der Tür 10 verlaufende Handbewegung einer vor der jeweiligen Tür 10 befindlichen Person erkannt wird, die einer Öffnungs- bzw. Schließbewegung bei Vorhandensein eines Türgriffs entsprechen würde. Um Fehlauslösungen zu vermeiden, wird eine Türbewegung nur dann initiiert, wenn die Bewegung eine bestimmte Mindestamplitude überschreitet, eine bestimmte Richtung und Geschwindigkeit aufweist und in einem bestimmten Bereich vor der Tür 10 vollzogen wird.Furthermore, an algorithm is stored on the control unit in order to move a specific door 10 using the associated motor, if a door 10 running perpendicular or at an angle to the plane of the door 10 using the camera and image recognition software Hand movement of a person in front of the respective door 10 is detected, which would correspond to an opening or closing movement in the presence of a door handle. In order to avoid false triggering, a door movement is only initiated when the movement exceeds a certain minimum amplitude, has a certain direction and speed and is carried out in a certain area in front of the door 10.

Die automatisch initiierte Türbewegung folgt der Handbewegung in ihrer Richtung, Geschwindigkeit und Amplitude. Die Türbewegung ist also so an die Handbewegung gekoppelt, wie dies auch bei einer manuellen Türöffnung der Fall wäre. Die Tür 10 wird geöffnet, wenn die Hand von der Tür 10 weg bewegt wird, die Türbewegung wird gestoppt, wenn diese Bewegung stoppt, und die Tür 10 wird geschlossen, wenn die Hand zur Tür 10 hin bewegt wird.The automatically initiated door movement follows the hand movement in terms of direction, speed and amplitude. The door movement is linked to the hand movement in the same way as it would be if the door were opened manually. The door 10 is opened when the hand is moved away from the door 10, the door movement is stopped when this movement stops, and the door 10 is closed when the hand is moved towards the door 10.

Daneben ist die Steuereinheit so ausgebildet, dass die jeweilige Tür 10 automatisch geschlossen wird, wenn anhand des Kamera und Bildauswertungssoftware ein Entfernen der Person erkannt wird, sowie wenn die Tür 10 eine bestimmte Zeit offen gestanden ist und zudem anhand des Kamera und Bildauswertungssoftware keine Person oder Aktivität vor der Tür 10 erkannt wird.In addition, the control unit is designed so that the respective door 10 is automatically closed if removal of the person is detected using the camera and image evaluation software, as well as if the door 10 has been open for a certain time and, in addition, no person or person using the camera and image evaluation software Activity is detected in front of door 10.

Des Weiteren ist ein Sicherheitssystem vorgesehen, das eine Kollision der Tür 10 mit einem Benutzer oder eine zu schnelle Bewegung oder zu hohe Kräfte vermeidet. Das Sicherheitssystem umfasst mehrere Aspekte. Zum einen ist vorgesehen, dass die Tür 10 unabhängig von einer etwaigen höheren Geschwindigkeit der Handbewegung immer nur mit einer maximalen Geschwindigkeit bewegt wird. Ferner umfasst der Motor einen Gegenkraftsensor, der eine durch Kollision der Tür 10 hervorgerufene Gegenkraft erkennt und die Türbewegung im Falle der Erkennung einer solchen Gegenkraft temporär stoppt. Des Weiteren wird die Türbewegung temporär gestoppt, wenn anhand der Kamera und Bildauswertungssoftware ein in der Bewegungsbahn stehendes Objekt erkennt.Furthermore, a safety system is provided that prevents the door 10 from colliding with a user or from moving too quickly or from excessive forces. The security system comprises several aspects. On the one hand, it is provided that the door 10 is only moved at a maximum speed regardless of any higher hand movement speed. Furthermore, the motor comprises a counterforce sensor which detects a counterforce caused by a collision of the door 10 and temporarily stops the door movement if such a counterforce is detected. In addition, the door movement is temporarily stopped when the camera and image evaluation software detects an object in the path of movement.

Anhand des gezeigten Zusammenschlusses lassen sich die Vorteile realisieren, dass kein Griff im Display-Bereich vorhanden ist und damit die Total Display Area im Vergleich zu bekannten Geräten gesteigert werden kann. Etwaige Transportbeschädigungen durch Griffelemente werden ebenfalls vermieden. Die verhältnismäßig schweren Glastüren werden durch den Motor geöffnet und nicht durch die Muskelkraft des Benutzers. Die Bedienung ist somit für jede Person ohne Einschränkungen möglich. Da der Erfassungsbereich für die erforderliche Handbewegung größer als der Eingriffsbereich eines klassischen Griffs sein kann, sodass auch Leute mit körperlichen Einschränkungen wie beispielsweise Rollstuhlfahrer, welche einen klassischen Griff nicht optimal fassen und zum Teil schwere Glastüren nur umständlich öffnen können, von einer derartigen gestengesteuerten Türbewegung profitieren. Zudem können Türen nach einer definierten Zeit automatisch geschlossen werden, um ein Offenbleiben der Türen zu vermeiden. On the basis of the connection shown, the advantages can be realized that there is no handle in the display area and thus the total display area can be increased compared to known devices. Any transport damage caused by handle elements is also avoided. The relatively heavy glass doors are opened by the motor and not by the muscle power of the user. Operation is therefore possible for every person without restrictions. Since the detection area for the required hand movement can be larger than the engagement area of a classic handle, so that people with physical limitations such as wheelchair users who cannot grasp a classic handle optimally and can sometimes only open heavy glass doors with difficulty, benefit from such a gesture-controlled door movement . In addition, doors can be closed automatically after a defined period of time to prevent the doors from staying open.
