Description

Einzugsvorrichtung für eine Schublade Feeding device for a drawer
Die vorliegende Erfindung betrifft eine Einzugsvorrichtung für eine Schublade mit einem mit der Schublade verbindbaren Zugmittel, einer einen Elektromotor aufweisenden Antriebseinheit und einer durch die Antriebseinheit antreibbaren Rolle zum Aufwickeln des Zugmittels.The present invention relates to a collection device for a drawer with a connectable to the drawer traction means, an electric motor having a drive unit and a driven by the drive unit roller for winding the traction means.
Eine derartige Einzugsvorrichtung geht beispielsweise aus der EP 465 800 A1 hervor, wobei der oberste Schuss einer als Zugmittel dienenden Stellstange lösbar mit einer als Waschmittelschale ausgebildeten Schublade verbunden ist. Durch einen Elektromotor kann die Stellstange und damit die Schublade sowohl aus- als auch eingefahren werden. Die Auslösung der Antriebseinheit erfolgt über eine vom Benutzer zu bedienende Taste.Such a collection device can be seen for example from EP 465 800 A1, wherein the uppermost shot of an actuating rod serving as a traction device is detachably connected to a drawer designed as a detergent shell. By an electric motor, the control rod and thus the drawer both off and retracted. The drive unit is triggered by a button to be operated by the user.
Aufgabe der Erfindung ist es eine gattungsgemäße Einzugsvorrichtung derart weiterzubilden, dass sich ihr Bedienkomfort erhöht.The object of the invention is to develop a generic collection device such that increases their ease of use.
Diese Aufgabe wird durch eine Einzugsvorrichtung mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a collection device with the features of claim 1.
Dadurch dass die Antriebseinheit (konkret: der Elektromotor der Antriebseinheit) durch ein Drehen der Rolle aktivierbar ist, kann das Auslösen eines am Möbelkorpus bzw. der Schublade angeordneten Schalters entfallen. Die Antriebseinheit kann stattdessen durch die Ausübung einer geringen manuellen Kraft durch den Benutzer auf die Schublade in Öffnungsrichtung erfolgen, da sich die hierdurch verursachte Bewegung der Schublade über das Zugmittel auf die Rolle überträgt und durch die resultierende Drehung der Rolle die Antriebseinheit aktivierbar ist.The fact that the drive unit (concretely: the electric motor of the drive unit) can be activated by turning the roller, the release of a arranged on the furniture body or the drawer switch can be omitted. The drive unit can instead be done by the exercise of a slight manual force by the user on the drawer in the opening direction, as this causes the movement of the drawer caused by the traction means on the roller and the drive unit can be activated by the resulting rotation of the roller.
Soll vorgesehen sein, dass das Zugmittel sowohl Zug- als auch Schubkräfte auf die Schublade übertragen kann, bietet sich die Ausbildung in Form eines eine gewisse Steifigkeit aufweisenden Zugmittels (beispielsweise in Form eines Stahlbandes) an.If it should be provided that the traction means can transmit both tensile and shear forces to the drawer, the training in the form of a certain stiffness traction means (for example in the form of a steel strip) offers.
Alternativ kann allerdings auch vorgesehen sein, dass das Zugmittel nur zur Ausübung von Zugkräften auf die Schublade ausgebildet ist. In diesem Fall kann es sich beim Zugmittel beispielsweise um einen Seilzug handeln. Im zweitgenannten Fall kann die Einzugsvorrichtung natürlich nur Kräfte auf die Schublade in Schließrichtung ausüben. In diesem Fall kann für das Ausstoßen der Schublade aus der Schließlage eine gesonderte Vorrichtung, beispielsweise ein Touch-Latch-Mechanismus, vorgesehen sein.Alternatively, however, can also be provided that the traction means is designed only for the exercise of tensile forces on the drawer. In this case, the traction means may be, for example, a cable pull. In the latter case, of course, the feeder can only exert forces on the drawer in the closing direction. In this case, for the ejection of the drawer from the closed position, a separate device, such as a touch-latch mechanism may be provided.
Weist das Zugmittel keine Steifigkeit auf (handelt es sich beispielsweise um einen Seilzug), muss dafür Sorge getragen werden, dass sich das Zugmittel ständig unter einer gewissen Spannung befindet, da andernfalls ein Einschieben der Schublade durch den Benutzer in Richtung der Schließlage nicht zwingend mit einer Drehung der Rolle verbunden wäre. Beispielsweise kommt es ohne zusätzliche Maßnahmen einfach zu einem Durchhängen des Seilzuges. In diesem Fall käme es nicht zu der an sich gewünschten Aktivierung der Antriebseinheit zur weiteren Unterstützung des Einzugsvorganges.If the traction means has no rigidity (if it is, for example, a cable pull), care must be taken to ensure that the traction means is constantly under a certain tension, since otherwise the drawer can not be inserted by the user in the direction of the closed position with a Rotation of the role would be connected. For example, it simply comes without additional measures to sag the cable. In this case, it would not come to the desired activation of the drive unit to further support the retraction process.
In diesem Zusammenhang kann vorgesehen sein, dass die Rolle von einer Feder (vorzugsweise einer Spiralfeder) in einer der beiden möglichen Drehrichtungen beaufschlagt ist. Vorzugsweise ist dabei vorgesehen, dass die Feder derart ausgebildet und zur Rolle angeordnet ist, dass sie sich durch eine mit dem Abwickeln des Zugmittels verbundene Drehung der Rolle auflädt. In diesem Fall wird bewirkt, dass sich das Zugmittel, welches ja mit der Schublade und der Rolle verbunden ist, im geöffneten Zustand der Schublade ständig unter Spannung befindet. Wird nun die Schublade aus der Öffnungslage durch den Benutzer leicht in die Schließlage bewegt, überträgt sich diese Bewegung über das gespannte Zugmittel auf die Rolle und die Antriebseinheit wird zur Unterstützung des weiteren Bewegungsvorganges aktiviert.In this context, it can be provided that the roller is acted upon by a spring (preferably a spiral spring) in one of the two possible directions of rotation. Preferably, it is provided that the spring is designed and arranged to the role that it charges by a connected to the unwinding of the traction means rotation of the roller. In this case, it is caused that the traction means, which is indeed connected to the drawer and the role, in the open state of the drawer is constantly under tension. If the drawer is now moved slightly out of the open position by the user into the closed position, this movement is transmitted to the roller via the tensioned traction means and the drive unit is activated to support the further movement process.
Falls die Einzugsvorrichtung nur zur Bewegung der Schublade in Richtung der Schließlage dient, sollte vorgesehen sein, dass die Antriebseinheit derart ausgebildet und/oder mit der Rolle gekoppelt ist, dass die Rolle in einer der beiden möglichen Drehrichtungen manuell im Wesentlichen frei drehbar ist. Hierdurch wird sichergestellt, dass der Bewegung der Schublade aus der Schließlage in die Öffnungslage (manuell oder durch eine gesonderte Vorrichtung) kein Widerstand durch die Antriebseinheit entgegengesetzt wird. In diesem Fall kann es allenfalls notwendig sein, die für die Aufladung der gegebenenfalls vorgesehenen Feder notwendige Kraft aufzubringen. Da die Feder nicht zum Einzug der Schublade, sondern nur zur Bereitstellung einer gewissen Spannung des Zugmittels dient, muss sie nicht besonders stark ausgebildet sein, weshalb auch keine großen Kräfte bei der Aufladung überwunden werden müssen. Weiters kann vorgesehen sein, dass die Rolle nur in einer der beiden möglichen Drehrichtungen durch die Antriebseinheit antreibbar ist.If the collection device only serves to move the drawer in the direction of the closed position, it should be provided that the drive unit is designed and / or coupled to the roller such that the roller is manually freely rotatable in one of the two possible directions of rotation. This ensures that the movement of the drawer from the closed position to the open position (manually or by a separate device) no resistance is opposed by the drive unit. In this case, it may at most be necessary to apply the force necessary for charging the optionally provided spring. Since the spring is not used to pull the drawer, but only to provide a certain tension of the traction device, it does not have to be particularly strong, which is why no major forces in the charge must be overcome. Furthermore, it can be provided that the roller can be driven by the drive unit only in one of the two possible directions of rotation.
Je nach Art der Entkoppelungsvorrichtung kann beispielsweise ein Mitnehmer an einem Ende des Zugmittels angebracht sein, über welche die Schublade nach erfolgter Einsetzung in den Möbelkorpus und Bewegung in die Schließlage wieder an das Zugmittel koppelbar ist.Depending on the type of decoupling, for example, a driver may be attached to one end of the traction device, via which the drawer can be coupled to the traction means again after the insertion into the furniture body and movement into the closed position.
Falls vorgesehen ist, dass das Zugmittel bei entkoppelter Schublade durch die Beaufschlagung der Rolle durch die Feder aufwickelbar ist, kann auch vorgesehen sein, dass die Antriebseinheit der Einzugsvorrichtung statt durch ein Drehen der Rolle durch die Betätigung eines von der Rolle unabhängigen Schalters auslösbar ist.If it is provided that the traction means in decoupled drawer by the application of the roller by the spring can be wound, can also be provided that the drive unit of the retraction device can be triggered instead of turning the roller by the operation of a switch independent of the roller.
Weiters kann vorgesehen sein, dass diese Schalteinrichtung als zweiteilige Kupplung ausgebildet ist, wobei der ein Teil drehfest mit dem Gehäuse der Antriebseinheit verbunden ist und der zweite Teil bei einer Drehung der Welle der Antriebseinheit mitdreht.Furthermore, it can be provided that this switching device is designed as a two-part coupling, wherein the one part is rotatably connected to the housing of the drive unit and the second part rotates with a rotation of the shaft of the drive unit.
Es wird auch Schutz beansprucht für eine Anordnung, welche eine Einzugsvorrichtung nach einem der vorgenannten Ausführungsbeispiele, eine in einem Möbelkorpus zwischen einer Öffnungslage und einer Schließlage bewegbar gelagerte Schublade und eine Koppelungsvorrichtung zum Koppeln bzw. Entkoppeln des Zugmittels der Einzugsvorrichtung an die bzw. von der Schublade umfasst.It is also claimed protection for an arrangement which a retraction device according to one of the aforementioned embodiments, a movably mounted in a furniture body between an open position and a closed position drawer and a coupling device for coupling or decoupling the traction means of the collection device to or from the drawer includes.
Bei einer derartigen Anordnung kann bevorzugt vorgesehen sein, dass die Einzugsvorrichtung derart ausgebildet ist, dass das Zugmittel bei entkoppelter Schublade durch die Beaufschlagung der Rolle durch die Feder aufwickelbar ist. In diesem Fall ist dieIn such an arrangement may preferably be provided that the retraction device is designed such that the traction means in decoupled drawer by the application of the roller by the spring can be wound up. In this case, the

Durch das Aufwickeln des Zugmittels wird sichergestellt, dass es bei entkoppelter und gegebenenfalls aus dem Möbelkorpus entnommener Schublade zu keinem Verheddern des Zugmittels kommt.Can cause pulling means. By winding the traction means ensures that it comes with decoupled and possibly removed from the furniture body drawer to no entanglement of the traction device.

Weiters kann eine Anordnung vorgesehen sein, bei der die Ausstoßvorrichtung zwar baulich getrennt von der Einzugsvorrichtung vorliegt, jedoch gemeinsam mit dieser an einem Montageelement angebracht ist.Furthermore, an arrangement may be provided in which the ejection device, although structurally separate from the retraction device, but is mounted together with this on a mounting element.
