Abstract

Mechanism for the automatic opening of a flap, door or drawer, characterized in that a flap (2), mounted without a distance to the body, by also touchless operation with the foot / hand, a switch / sensor / motion detector (5), by means of a Elektropermanentmagnet / solenoid (3) via a spring / gas pressure spring (4), can be opened automatically.

Description

Flaps, doors or drawers of furniture of conventional design can only be opened and closed by hand. There is a mechanism that can be mounted that opens and closes a flap with the human knee. To trigger the mechanism, a distance of the flap to the body is required. The ballpoint pen principle. It is not possible to achieve a uniform level when installing with adjacent fronts. This cumbersome to install mechanism is susceptible to repair, makes by the mounted springs and the locking mechanism unpleasant noise and a subdued overall impression.

The protection specified in claim 1 invention is based on the problem to provide a mechanism that automatically opens the door fitting on the body, door or drawer after pressing a shutter -also contactless and can be closed again without contact with the hand. This is necessary, inter alia, in the medical field, for example for opening a flap of a trash can.

This problem is solved with the features listed in the protection claim 1.

With the invention it is achieved that the flap, door or drawer, because mounted without clearance, inserts in a uniform plane. It is achieved that the flap, door or drawer by hand and / or foot on a trigger / switch -also without direct contact- automatically opens, and also without having to touch them by hand, fatigue-free and power-saving z. B. with the knee, close again.

An advantageous embodiment of the invention is shown in the protection claim 2. The use of an LED spotlight / laser or similar, which marks the contact point for opening.

A further advantageous embodiment of the invention is shown in the protection claim 3. The use of a reed contact which switches off the LED spot / laser or similar when it is open.

An embodiment of the invention will be described with reference to 1 to 3 shown. Show it

1 , the side view, when closed;

2 , the side view, when open;

3 , the front view, in the closed state;

In the figures, it can be seen that the mechanism mounted in the body on the right-hand side, gas spring ( 4 ), above the magnet ( 3 ) and the adjustable spring ( 6 ), as well as the reed contact ( 7 ) to interrupt the circuit for the LED lamp ( 8th ).

In the bottom plate is the sensor ( 5 ) and the LED Spot ( 8th ). The means of hinge ( 1 ) fitted on the body flap ( 2 ). Suggested on 3 , the waste bin installed and the partition wall;

When operating the sensor ( 5 ) z. With the foot, depending on the type of magnet used, either the force of the electro-permanent magnet ( 3 ) or the electromagnet ( 3 ) and then, the flap ( 2 ) first by an adjustable spring ( 6 ) is pushed forward until the force of the gas spring ( 4 ) and the flap -Here as an example with mounted waste bin ( 9 ) - opens to the desired stop.

To trigger the mechanism could also z. As a switch with (radio) remote control or a noise switch, etc. are used.

This process is also possible without the adjustable spring ( 6 ) possible, because then but the gas spring ( 4 ) must be mounted more in the horizontal direction, this requires an increased effort to close the flap.

It is using the appropriate gas spring (s) ( 4 ) and their position and the magnet and their position possible, from the empty basket ( 9 ) up to several kg of contents the flap ( 2 ) to open automatically.

The system illustrated in the example is powered either by 12 V / 24 V power supply or by battery or rechargeable battery. The installation therefore does not have to be carried out by a qualified electrician.

The LED spot located on the bottom of the cabinet ( 8th ) generated on the floor below the sensor ( 5 ) a light point and thereby serves as a marker for the next to the LED spot ( 8th ) also mounted on the ground sensor ( 5 ). The LED Spot ( 8th ) is replaced by the reed contact ( 7 ) and the flap ( 2 ) attached magnet ( 7a ). Once the flap ( 2 ) the lamp goes out. For triggering the mechanics, the LED spot ( 8th ) including reed contact ( 7 ) not mandatory.

The marking can also be done by a label at a suitable location. The use of a sensor with integrated spot is conceivable.

When opening and closing the flap ( 2 ) do not cause unpleasant noises.
