Description

The invention relates to a hinge for a folding flap with a first folding element and a second folding element which in a closed position on a common vertical plane are arranged, for connecting the first folding element with the second folding element comprising a fastening element, a first Arm and a second arm.

The fastener has a first mounting surface with which it to the first folding element fitting can be fastened. The first arm is around a first Swivel axis between a first position and a second position pivotally connected to the fastener. The second arm has attachment means on, with which the second arm can be fastened to the second folding element. furthermore it is about a second pivot axis, which is arranged parallel to the first pivot axis is pivotable between a first position and a second position connected to the first arm. In a closed position, the folding elements in each case one abutting edge, which are arranged parallel to one another.

Such a hinge is shown in FR 1 508 270 with a fastener that has a has first mounting surface and is attachable to a first door. Further the hinge has a first arm pivotable about a pivot axis is connected to the fastening element. Furthermore, a second arm is provided, which can be fastened via fastening means with a second door leaf. About that In addition, the second arm is pivotable about a second pivot axis with the first Arm connected.

Other known hinges include a first fastener fixedly attached to a surface of the first pleat member and a second fastener fixedly attached to a surface of the second pleat member. The two fastening elements are pivotally connected to each other about a pivot axis, which extends along the abutting edges of the folding elements. Problems occur when fold flaps and folding doors which are asymmetrical foldably to each other, that is, in which the pivot axis does not extend close to the joint edges, but in which the pivot axis relative to the surface of one of Fa _l tele elements displaced parallel to the joint edges is arranged. In this case, in known hinges, an arm of the first fastening element projects in the plane of the folding element beyond the respective abutment edge. At a free end of the arm, the first fastener is pivotally connected to the second fastener. In this case, the pivot axis has approximately the same distance to the abutting edge of the first folding element as to the second folding element. When opening the folding flap or the folding door thus creates a gap between the two folding elements. This gap is a source of danger when closing, as a person can reach into the gap and pinch his hand when closing.

The object of the present invention is to provide a hinge which is asymmetrical Split flaps or folding doors can be used without for A person is in danger of getting hurt if the folding door or the folding door is closed.

According to the invention the object is achieved by an aforementioned hinge, wherein the first arm in the first position, which occupies this in the closed position and an open position of the folding lid, a smallest angle to the mounting surface,
the first arm in the second position, which assumes this in an intermediate position of the folding lid, enclosing a largest angle to the mounting surface,
in the first position of the second arm, which occupies this in the closed position of the Faltdeckels, the first arm and the second arm the smallest angle to each other and include
in the second position of the second arm, which occupies this in the open position of the Faltdeckels, the first arm and the second arm enclose the largest angle to each other.

When using this hinge in a folding flap or a folding door can thus, starting from a closed position in which the two folding elements on a common Lie flat and the first arm in its first position and the second arm in its first position, the abutting edge of the first folding element is from the second Folding be moved away, the first arm transferred to its second position is and is slightly pivoted relative to the second arm. Thus arises between the abutting edge of the first folding element and the abutting edge of the second Folding a gap. When closing the folding door or the folding door this can Gap in the closed position, so that a person in the closed position Gap has seized, not hurt.

In order to ensure that the two folding elements in the normal state of the closed position, that means if there is no manual intervention and thus no gap between the folding elements is given, are arranged on a common plane, is the first Arm acted upon by spring means to its first position.

For this purpose, the first arm, starting from the first pivot axis, a lever be formed, by means of a spring element is supported against the fastener.

To the pivoting of the first arm to its second position To limit, the lever serves as a stop against the fastener.

A simple structure of the hinge, especially in a Manufacture of the hinge made of plastic, can be ensured be that the first arm by means of a film hinge is connected to the fastening element. A separate spring element can be avoided by the fact that the film hinge is resilient and thus as spring means serves.

So that a defined movement sequence when opening and closing the folding flap or the folding door is guaranteed points the fastener on a control contour, wherein the first Arm is associated with a lock slider, on the one hand resilient against the first arm and on the other hand with a footprint is slidably supported against the control contour and wherein the Locking slide in the first position of the first arm in one Locking recess of the adjusting contour engages. For swivel movements of the first arm slides against the fastener the lock slider thus with its footprint on the control contour from. Since the lock slider in the first position of the first Arms engages in the detent recess, is the first arm held in its first position. For normal movements during opening or closing of the folding flap or the folding door is the first arm thus safe in its first Position held. Only when closing the folding flap or the folding door a person between the first folding element and the second folding element engages, becomes the first arm moved from its first position, with the lock slider off the detent recess is moved against a spring force.

It can be provided that the setting contour starting from the Detent recess up to that contact point, the lock slider achieved with the control contour when the first arm in his second position is convicted, a constant distance to the first pivot axis. This will ensure that the lock slider only when moving out of the Locking recess must be moved against a spring force. in the further course of the pivoting path of the first arm to the second Position, the lock slider is no longer against the spring force moved, so that no torque exerted on the first arm becomes.

To ensure a defined end stop of the second arm can be provided that the lock slider in the second position of the first arm in abutment with an end stop the adjusting contour is.

Preferably, the second attachment means are by a second attachment surface shown, with which the second Arm can be fastened to the second folding element.

Here are usually the first mounting surface and the second attachment surface is arranged on a common plane, when the first arm in the first position and the second arm is in the first position.
