DE102008045248A1 - Hinge for e.g. opening of door of cabinet, has set of side pieces provided with common edges that are jointly connected with each other, and pressure area controlled and subjected with pneumatic or hydraulic pressure - Google Patents

Abstract

The hinge (1) has a set of side pieces (9, 10) provided with common edges that are jointly connected with each other, where one of the side pieces is connected with a common shaft (2). The shaft runs coaxially to a connecting axle of the side pieces, and exhibits a pressure area radially emanating from the shaft. The pressure area is controlled and subjected with pneumatic or hydraulic pressure, to shift the shaft into a rotating movement, which leads to a relative movement of the side pieces of the hinge or guided away from each other.

Description

When Hinge is the name of a part that has two levels on one side common edge are connected. The two levels can also be referred to as legs.

One Such hinge can serve to move a room through a movable Part to close. For example, consider one Furniture, so the doors are usually on it held by hinges. These are made possible by a Pivoting movement of the door, the opening in the piece of furniture to access or close.

The For this required pivoting movement is done manually, d. H. the Person opening the furniture or the door would like to pull on a handle, knob or the like. The door on.

It Now there are situations where the person is unable to complete this opening process be it because of a disability or for example, the person at the moment no hand free Has.

Consequently There is quite a desire to open the door automatically or to cause it to close.

From the DE 203 08 256 U1 It is known to provide for linearly movable furniture elements, such as a drawer, a drive, as a piston-cylinder unit, in which - depending on the version - the piston with the associated piston rod or the cylinder is moved relative to the other part of the unit , This relative displacement corresponds to the extension of the drawer.

From the DE 91 132 23 U1 an electric motor drive for a drawer of a cabinet is known.

The DE 10 2004 045 568 A1 discloses in this context possibilities of controlling the opening and closing operation, for example by means of a light barrier or a voice control device.

Of the Invention has for its object to provide a hinge, with also a fully automatic opening, for example reach a cabinet door of a piece of furniture leaves.

Solved this object is achieved by a hinge, in which the common edges of the legs hinged together are connected, wherein one of the legs connected to a shaft is, which is coaxial with the connecting axis of the legs and in turn a radially outgoing from the shaft pressure surface having controlled with pneumatic or hydraulic pressure acted upon to set the shaft in a rotational movement, the one to a relative movement of the legs of the hinge to each other leads to or away from each other.

Preferably is the pressure surface connected to the shaft as one in a circular cylinder circumferential piston surface formed.

The from the piston surface and the round cylinder existing piston-cylinder unit is to a pressure source, such as a compressor or a hydraulic pump, connected.

The Actuation of the hinge, d. H. in the special case, the opening or closing a door of a piece of furniture, requires the pressurization of the piston surface, and This is done by a pressure source with an on and off element connected, which can be triggered manually or without contact is.

Preferably Embodiments for this purpose are a pressure source over a radio transmitter and receiver triggerable and controllable or via a capacitive sensor.

According to the invention while the radio transmitter or the capacitive sensor via a single ladder with a metallic handle on the door or knob be connected in such a way that when touching the Handle with your hand through the body's own tension Impulse is transferable.

For an automatic monitoring or actuation It is advantageous if in or on the piston-cylinder unit a device for determining the position of the piston surface is provided.

The Invention is intended below to an embodiment shown in the drawing be explained.

there the figure shows schematically the arrangement of an inventive Hinge on a door or wall of a piece of furniture.

In the drawing, the stationary wall of a piece of furniture with 8th while the door to be opened or closed with 4 is designated.

The thigh 9 and 10 of the hinge 1 are integrated into this or connected to this, wherein the connection to a common shaft 2 is provided. This wave is in turn with a col benfläche connected, the pressure can be applied.

This piston surface is located in a round cylinder, which is part of the piston-cylinder unit 3 is.

If the piston surface in the round cylinder is pressurized by the pressure source, not shown here, either hydraulically or pneumatically, the shaft is rotated 2 and thus movement of the legs of the hinge towards or away from each other, so that so that the door can be closed or opened.

implied is in the drawing still a way of triggering the pressure source, ie the operation of the hinge.

With 5 is a standard, metallic handle on the outside of the door. This is about a single conductor 11 with a capacitive sensor 6 in conjunction, leaving a light touch of the handle 5 an impulse is transmitted to the sensor, which then turns on the pressure source.

Also indicated in the drawing is the arrangement of a proximity switch 7 with which a shutdown of the pressure source can be done at the end position reached.
