Abstract

Mechanism for the automatic opening of a flap, door or drawer even without electric current characterized in that thus a flap (2) mounted without a distance to the body, by operating a mechanism (13) via a trigger (15), for example with the foot / the hand, via a spring / gas spring (4), even without power, automatically open.

Description

Flaps, doors or drawers of furniture of conventional design can only be opened and closed by hand.

In the priority application AktZ .: 20 2017 003 531.6 from 05.07.2017 a mechanism is described, which can be mounted, which opens a flap, by means of a gas spring via an electric magnet, controlled by a sensor.

Since the magnet used and the sensor must be supplied with electric current, it is not possible to operate the mechanism without the connection of a battery / battery or directly to the mains.

The protection specified in claim 1 invention is based on the problem to create a mechanism that automatically opens the fitting on the body flap, door or drawer after pressing a shutter without electrical power and you can close 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, if no electrical current is to be used.

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 opens automatically by hand and / or foot via a trigger even without electrical current, and also without touching it by hand, fatigue-free and power-saving, for example. with the knee, close again.

It is achieved that the flap, door or drawer, because it is mounted without clearance, fits in a uniform plane.

An advantageous embodiment of the invention is shown in the protection claim 2.

Thus, the mechanical release (15) can be replaced by a suitable electrically operated release.

A further advantageous embodiment of the invention is shown in the protection claim 3.

Thus, the mechanism can be mounted at a lateral enlargement of the flap (2), outside the body or an intermediate wall (10) for the spatial separation from the body inside to the mechanism can be used.

• 1.1, die Seitenansicht, bei geschlossenem Zustand;
• 1.2, die Seitenansicht, bei geöffnetem Zustand;
• 1.3, die Vorderansicht, bei geschlossenem Zustand;

An embodiment of the invention will be described with reference to 1 .1 to 1.3 are shown. Show it

• 1 .1, the side view, when closed;
• 1 .2, the side view, when open;
• 1 .3, the front view, when closed;

In the Fig. As a way of mounting can be seen, which is in the body above, mounted on the right side housing (13) , with the magnet in the carriage (11) , the feather (12) , the metal disc (3a) , the gas spring (4) , as well as the cable (14) , the required (foot) trigger (15) and the hinge (1) ,

In 1 .3 additionally recognizable, is the possibility of mounting an intermediate wall (10) , as a spatial separation from the body to the mechanism, which can be mounted on both sides.

When pressing the shutter button (15) eg with the foot, the magnet in the carriage (11) by means of the cable (14) moved down.

As soon as the magnet (11) no longer in the area of the metal plate (3a) and the magnetic force is not on the metal plate (3a) acts, sets the force of the gas spring (4) a, shut up (2) is pressed forward and opens until the desired stop.

To move the magnet (11) can be the trigger (15) depending on the construction of the same (electrical or mechanical) and the position, by foot, knee, by hand or otherwise triggered.

It is using the appropriate gas spring (s) (4) and their position and the / the magnet (s) (11) and their position possible, from the empty basket (9) up to several kg contents the flap (2) automatically open.

When opening and closing the flap (2) No unpleasant noises are generated.

Claims (8)

Mechanism for the automatic opening of a flap, door or drawer even without electric current characterized in that thus a flap (2) mounted without a distance to the body, by operating a mechanism (13) via a trigger (15), for example with the foot / the hand, via a spring / gas spring (4), even without power, automatically open. Mechanism after Claim 1 , characterized in that the mechanical trigger (15) can be replaced by an electrically operated mechanism. Mechanism according to one of the existing claims, characterized in that the housing (13) for opening, the hinge (1) as well as the gas pressure spring (4) at a lateral enlargement of the flap (2), outside the body can be mounted or an intermediate wall (10), left or and right, for the spatial separation of the body inside to the housing (13), hinge (1) and the gas spring (4) can be used. Mechanism according to one of the existing claims, characterized in that, depending on the length, force and position of the gas spring (4), and the strength and position of the magnet used (11), eg due to a technical defect without triggering the mechanism (13) , which leaves the flap (2) / door / drawer open by hand. Mechanism according to one of the existing claims characterized in that, depending on the length, force and position of the gas spring (4), and the strength and position of the magnet (11) used, the flap (2) / door can be opened at a different angle , For drawers this affects the extension length. Mechanism according to one of the existing claims, characterized in that the housing (13) for moving the magnet (11) can be mounted so that the magnet (11) can be moved sideways, upwards or downwards as in the example. Also, the magnet (11) - in the housing (13), for example, mounted below - in the direction of the body inwardly -also horizontal- be moved away from the metal plate (3a). Mechanism according to one of the existing claims, characterized in that no matter at which of the possible positions the housing (13) is mounted, the magnet (11) in the door / flap and the metal disc (3a) can instead be mounted in the housing (13) , Mechanism according to one of the existing claims characterized in that, the housing (13) both left and right, above, and for example, a larger and synchronous power transmission, by means of a second cable (14), can be mounted on both sides.
