Abstract

Mechanism for the automatic opening of a flap, door or drawer, 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 / 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 application Act Z .: 20 2017 003 531.6 dated 05.07.2017 a mechanism is described, which can be mounted, which opens a flap, by means of a gas spring on 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 by hand and / or foot on a trigger without electricity, automatically opens, and also without having to touch them by hand, fatigue-free and power-saving, for example, with the knee, close again.
It is achieved that the flap, door or drawer, because mounted without distance to the body, inserts in a uniform level.

An advantageous embodiment of the invention is shown in the protection claim 2.
For example, an accidental opening of the flap ( 2 ), and a larger contact pressure of the magnet ( 11 ), instead of the metal disc as a counterpart a second magnet ( 3b ).

A further advantageous embodiment of the invention is in the protection claim 3 shown.
Thus, the mechanism in a lateral enlargement of the flap ( 2 ), are mounted outside the body or an intermediate wall ( 10 ) are used for the spatial separation of the body inside to the mechanism.

Also an advantageous embodiment of the invention is in the protection claim 4 shown.
So the flap ( 2 ) / Door / drawer, for example, in case of a technical defect, be opened by hand.

• 1.1, die Seitenansicht, bei geschlossenem Zustand;
• 1.2, die Seitenansicht, bei geöffnetem Zustand;
• 1.3, die Vorderansicht, bei geschlossenem Zustand;
• 1.4, die Seitenansicht, geschlossenen, mit zweitem Magneten;

An embodiment of the invention will be described with reference to 1 .1 to 1.5. Show it

• 1 .1, the side view, when closed;
• 1 .2, the side view, when open;
• 1 .3, the front view, when closed;
• 1 .4, the side view, closed, with second magnet;
• 1 .5, side view, open, with second magnet;

In the figures, as a possibility of assembly is apparent, the body in the top, mounted on the right side housing ( 13 ), with the magnet in the carriage ( 11 ), the feather ( 12 ), the metal disc ( 3a ), the second magnet ( 3b ), the gas spring ( 4 ), as well as the cable ( 14 ), the required (foot) trigger ( 15 ) and the hinge ( 1 ).

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

In 1 .4 and 1.5 additionally recognizable, is the possibility of mounting a second magnet ( 3b ), which instead of the metal disc ( 3a ) can be mounted.

When the shutter button is pressed ( 15 ) eg with the foot, the magnet in the slide ( 11 ) by means of the cable ( 14 ) moves down.

As soon as the magnet ( 11 ) no longer in the area of the metal plate ( 3a ) or the second magnet ( 3b ) and the magnetic force is not on the metal plate ( 3a ) or the second magnet ( 3b ), the force of the gas spring ( 4 ), the flap ( 2 ) is pushed forward and opens until the desired stop.

To move the magnet ( 11 ) the trigger ( 15 ) depending on the construction of the same (electric 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 magnet (s) ( 11 ) or second magnet ( 3b ) and their position possible, from the empty basket ( 9 ) up to several kg of contents, the flap ( 2 ) to open automatically.

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

Claims (9)

Mechanism for automatically opening a flap, door or drawer, 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 / hand , via a spring / gas pressure spring (4), even without power, automatically open. Mechanism after Claim 1 , characterized in that, also in order to increase the contact pressure, instead of the metal plate (3a), a second magnet (3b) can be attached. 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 of the body can be mounted or ., an intermediate wall (10), left or and right, for the spatial separation of the body interior 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), as well as the strength and position of the magnet (11) used, eg due to a technical defect, without the mechanism (13) trigger the door (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 horizontally-away from the metal disc (3a) and the second magnet (3b). 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 flap (2) / door / drawer and the metal disc (3a) instead in the housing ( 13) can be mounted. Mechanism according to one of the existing claims, characterized in that, both the housing (13) and the metal plate (3a), and the second magnet (3b) left and right, above, as well as for example, a larger and more synchronous power transmission, with the help a second cable (14), both sides or at several points can be mounted simultaneously. Mechanism according to one of the existing claims, characterized in that the mechanical trigger (15) can be replaced by an electrically operated mechanism.
