Abstract

The present invention relates to a body, in particular a cabinet, comprising a part, e.g. a door or a panel, which is pivotable between two positions, driven by an electric motor, wherein said part actuates during its closing movement a control device that activates the motor. A separate sensor, which reacts to the movements of the control device and is arranged between the control device and the motor, is capable of modifying the motor power.

Description

Körper mit elektromotorisch zwischen zwei Positionen verschwenkbaren Teilen Body with parts that can be pivoted between two positions by an electric motor
Bei herkömmlichen Körpern, insbesondere Schränken, werden die Klappen oder Schubladen motorisch angetrieben, wobei der Schaltvorgang in der Regel über einen Stößel ausgelöst wird, der an der Stoßstelle zwischen der Klappe und dem Korpus des Schrankes angeordnet ist. In conventional bodies, in particular cabinets, the flaps or drawers are motor-driven, with the switching process usually being triggered by a plunger which is arranged at the joint between the flap and the body of the cabinet.
Die Hubbewegung des Stößels ist dabei relativ groß, so dass der Schaltvorgang erst in der fast eingefahrenen Position des Stößels ausgelöst wird. The lifting movement of the ram is relatively large, so that the switching process is only triggered when the ram is almost in the retracted position.
Da die Schubladen und Klappen mit großen Maßen auch größere Toleranzen aufweisen, setzt der Schaltvorgang voraus, dass die Klappe oder die Schublade im Bereich des Stößels betätigt wird oder der Stößel fast eingefahren werden muss, um den Schaltvorgang auszulösen. Handelt es sich um relativ große oder breite Klappen/Schubladen, dann erfolgt eine wirksame Betätigung des Stößels entweder erst in annähernd geschlossenem Zustand der Klappe oder der Benutzer muss die Klappe im Bereich des Stößels bzw. den Stößel individuell betätigen. Since the drawers and flaps with large dimensions also have larger tolerances, the switching process requires that the flap or drawer is actuated in the area of the ram or the ram has to be almost retracted in order to trigger the switching process. If the flaps/drawers are relatively large or wide, then the push rod is only actuated effectively either when the flap is almost in the closed state, or the user has to actuate the flap in the area of the push rod or the push rod individually.
Dies wird bei Schränken als Nachteil empfunden. This is perceived as a disadvantage for cabinets.
Ausgehend von dem obigen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, hier Abhilfe zu schaffen. Proceeding from the above prior art, the object of the invention is to remedy this situation.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Stößel mit einem Sensor zusammenarbeitet, der bereits auf minimale Bewegungen des Stößels ein Signal generiert, durch das der Motor aktiviert wird. The stated object is achieved according to the invention in that the ram works together with a sensor which generates a signal as soon as the ram moves minimally, by means of which the motor is activated.
Man erkennt, dass die Erfindung jedenfalls dann verwirklicht ist, wenn zwischen einem herkömmlichen Stößel (Taster) und der Motorsteuerung ein Sensor angeordnet ist, der empfindlich auf Bewegungen des Stößels reagiert und somit die Aktivierung des Motors, also sein Ein- und Ausschalten, bereits bei minimalem Hub des Stößels auslöst. It can be seen that the invention is implemented in any case when a sensor is arranged between a conventional tappet (button) and the motor controller, which reacts sensitively to movements of the tappet and thus activates the motor, i.e. switches it on and off minimum stroke of the ram triggers.
Weitere zweckmäßige und vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor. Further expedient and advantageous configurations of the invention emerge from the dependent claims.
Ein Ausführungsbeispiel der Erfindung geht aus den Zeichnungen hervor. Es zeigen: An embodiment of the invention is apparent from the drawings. Show it:
Fig. 1 einen Schrank mit einer ausgeschwenkten Klappe Fig. 1 shows a cabinet with a pivoted flap
Fig. 2 den Schrank nach Fig. 1 mit eingeschwenkter Klappe Fig. 2 shows the cabinet according to FIG. 1 with the flap pivoted in
Fig. 3 den Schrank nach Fig. 1 mit eingeschwenkter Klappe und einer Steuerungseinheit mit einem Stößel mit Sensor Fig. 4 den Schrank nach Fig. 1 mit gedrückter Klappe und einer betätigten Steuerungseinheit mit einem Stößel mit Sensor 3 shows the cabinet according to FIG. 1 with the flap pivoted in and a control unit with a plunger with a sensor 4 shows the cabinet according to FIG. 1 with the flap pressed and an actuated control unit with a plunger with a sensor
Fig. 5 eine Steuerungseinheit mit einem Stößel und einem Hall-Sensor zwischen 2 Magneten angeordnet 5 shows a control unit with a plunger and a Hall sensor arranged between 2 magnets
Fig. 6 eine Steuerungseinheit mit einem Stößel und einem Hall-Sensor seitlich neben 2 Magneten angeordnet 6 shows a control unit with a plunger and a Hall sensor arranged on the side next to 2 magnets
Fig. 7 einen Schrank mit einer ausgeschwenkten Klappe ohne hervorstehenden Stößel 7 shows a cupboard with a pivoted-out flap without a protruding plunger
Fig. 8 den Schrank nach Fig. 7 mit Magnet an eingeschwenkter Klappe und einer Steuerungseinheit mit Sensor FIG. 8 shows the cabinet according to FIG. 7 with a magnet on the folded-in flap and a control unit with a sensor
In den Figuren ist ein Schrank 1 mit einer Klappe 2 dargestellt, die um eine Achse 4 verschwenkbar ist. Etwa in der Mitte des Schrankes ist eine an eine Antriebseinheit 3 angeschlossene Steuerungseinheit 5 mit einem Stößel 9 angeordnet, die in Richtung des Doppelpfeiles 11 hin und her bewegbar und federbelastet ist. Nimmt die Klappe 2 ihre Schließstellung ein (Fig. 2, 3), dann betätigt sie den Stößel 9, der in den Schrank 1 eingefahren wird. In the figures, a cabinet 1 is shown with a flap 2 which can be pivoted about an axis 4 . Arranged approximately in the middle of the cabinet is a control unit 5 which is connected to a drive unit 3 and has a plunger 9 which can be moved back and forth in the direction of the double arrow 11 and is spring-loaded. If the flap 2 is in its closed position (FIGS. 2, 3), then it actuates the plunger 9, which is moved into the cabinet 1.
Der Stößel 3 (Fig. 4) trägt zwei Magnete 17, zwischen dem ein Hall-Sensor angeordnet ist. Im Bodenbereich ist eine Rückholfeder 13 angeordnet, die bestrebt ist, den Stößel nach außen zu fahren. Der Hall-Sensor 10 ist ortsfest angeordnet, während die Magneten 17 der Bewegung des Stößels 9 folgen, so dass die Position des Sensors zwischen den Magneten 17 veränderbar ist. Aufgrund dieser Änderung der Lage des Sensors generiert dieser ein Signal, das eine Steuerungseinheit des Motors aktiviert. Die Besonderheit des Sensors besteht insbesondere darin, dass schon geringe Bewegungen des Stößels, und somit auch der Magnete, ein hinreichendes Signal erzeugen, um den Motor zu aktivieren. The plunger 3 (Fig. 4) carries two magnets 17 between which a Hall sensor is arranged. A return spring 13 is arranged in the bottom area and strives to drive the ram outwards. The Hall sensor 10 is stationary, while the magnets 17 follow the movement of the plunger 9, so that the position of the sensor between the magnets 17 can be changed. Due to this change in the position of the sensor, it generates a signal that activates a control unit of the engine. The special feature of the sensor is that even small movements of the tappet, and thus also of the magnets, generate a sufficient signal to activate the motor.
