Body comprising parts which are pivotable between two positions, driven by an electric motor

Abstract

The present invention relates to a body, in particular a cabinet, with a part that can be pivoted between two positions by an electric motor, for example a door or panel. During its closing movement, the body, in particular the cabinet, actuates a control device that activates the motor. A separate sensor, which reacts to the movements of the control device and by means of which the motor output can be changed, is arranged between the control device and the motor.

Claims

1. A body with a part that can be pivoted between two positions via an electric motor, the part is configured to actuate a control device in the course of its closing movement activating the motor, wherein a separate sensor is arranged between the control device and the motor, wherein the separate sensor is responsive to movements of the control device, wherein the separate sensor is configured to activate the motor in response to movements of the control device, wherein the control device carries two separate permanent magnets arranged at a distance from one another, wherein the sensor is arranged between the two magnets, wherein the control device exerts linear reciprocating movements in the course of its actuation.

2. The body according to claim 1, wherein the two permanent magnets are spaced apart from each other in the direction of movement of the control device.

3. The body according to claim 1, wherein the two permanent magnets lie on a line that is parallel to a longitudinal axis of the control device.

4. The body according to claim 1, wherein the sensor is located along the direction of movement of the control device within a recess formed within the control device.

5. The body according to claim 1, wherein the sensor is located laterally next to the control device.

6. The body according to claim 1, wherein the two magnets include magnetic poles, wherein the two magnets are aligned with the same magnetic poles towards each other in direction of the sensor.

7. The body according to claim 1, wherein during the movement of the control device, the relative position of the sensor can be changed in relation to the two magnets.

8. The body according to claim 1, wherein the sensor is a Hall sensor whose output signal controls the motor.

Description

(1) An embodiment of the invention is apparent from the drawings. They show:

(2) FIG. 1 a cabinet with a pivoted flap,

(3) FIG. 2 the cabinet according to FIG. 1 with the flap pivoted in,

(4) FIG. 3 the cabinet of FIG. 1 with pivoted flap and a control unit with a plunger with sensor,

(5) FIG. 4 the cabinet of FIG. 1 with the flap pressed and an actuated control unit with a plunger with sensor,

(6) FIG. 5 a control unit with a tappet and a Hall sensor arranged between 2 magnets,

(7) FIG. 6 a control unit with a plunger and a Hall sensor arranged on the side next to 2 magnets,

(8) FIG. 7 a cupboard with a pivoted-out flap without a protruding one plunger,

(9) FIG. 8 the cabinet according to FIG. 7 with a magnet on the folded-in flap and a control unit with a sensor.

(10) In the figures, a cabinet 1 with a flap 2 is shown. The flap 2 can be pivoted about an axis 4. A control unit 5 connected to a drive unit 3 and having a plunger 9 is arranged approximately in the middle of the cabinet. The control unit 5 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.

(11) The plunger 9 (FIG. 4) carries two magnets 17 between which a Hall sensor is arranged. A return spring 13 is arranged in the bottom area. The return spring 13 strives to move the plunger outwards. Hall sensor 10 is stationary. On the other hand, 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 plunger, and thus also of the magnets, generate a sufficient signal to activate the motor.
