Description

The invention relates to a door hinge for a concealed arrangement between the door frame and door with two receiving bodies, which are insertable into recesses in the door and in the frame and a first hinge and a second hinge, which are pivotally connected about a vertical connecting axis.

A door hinge with the features described above is made DE 202 13 155 U1 known. In each of the receiving body one of the hinge bracket is rotatable and the other slidably mounted and rotatably mounted in a straight guide recess. Each of the hinge bracket is rotatably mounted at one end and slidably guided at the other end. During a pivoting movement, the door leaf rotates about a fixed axis of rotation. For doors with door leaves and door frames, which have overlapping folds or projections on the inside of the door and on the outside of the door, the door hinge described can not be used, since the projections would block the opening movement about the vertical axis of rotation. Such folds or projections typically have door wings and door frames, which are composed of frame profiles made of plastic or metal.

From the GB 445 406 A a hinge for a vehicle door is known, which is mounted with a first receiving body on a vehicle door and a second receiving body on a frame of the vehicle door. The hinge comprises a first and a second hinge bracket, which are pivotally connected about a vertical connecting axis. The first hinge bracket is rotatably mounted at one end about a first vertical axis of rotation in one of the receiving body and at the other end about a second vertical axis of rotation in the other receiving body. Of the second hinge bracket is slidably and rotatably supported at both ends in each guide in recesses of the receiving body, wherein the kinematics of the hinge is determined by the interaction of the second hinge bracket with the guide recesses.

The invention has for its object to provide a door hinge between the door frame and door for the concealed arrangement in which the pivot point changes depending on the tilt angle in a predetermined manner. The door hinge should be used in particular for doors with door closing position overlapping door leaf and door frame profiles.

The object is achieved by a door hinge according to claim 1. Due to the design of the shape of the hinge bracket, the positioning of the first and second vertical axis of rotation and in particular by the shape of the guide recesses, the course of a pivoting movement of the door hinge according to the invention can be varied in many ways. According to the invention, the S-shaped course of the guide recesses predetermines the movement of the door leaf during the pivoting movement in such a way that the entire pivoting movement successively passes through pivoting ranges in which different movements are carried out. In this case, the movement sequence is determined by the shape of the guide recesses, that the connection axis pivots in one of the pivoting ranges, which is at least 60 degrees, about a vertical axis of rotation of the first hinge bracket and in another pivoting range, which is at least 60 degrees, their spatial Retains location relative to the door frame. Such a movement of the connection axis can be achieved in that the first hinge bracket turns from the door closed position in a first pivoting range of at least 60 degrees about the first and not about the second vertical axis of rotation and that a second Pivoting range of at least 60 degrees is provided, in which the first hinge bracket rotates about the second and not about the first vertical axis of rotation. This movement sequence can be realized in a simple manner by virtue of the fact that, in the first pivoting area, one end of the second hinge bracket is guided in a circular arc around the first vertical axis of rotation in the guide recesses of the receiving body associated with the first vertical axis of rotation and that in the second pivoting area the other end of the second second Schamierbügels is also guided in the guide recesses of the other receiving body in a circular arc about the second vertical axis of rotation. The door hinge is thus also applicable to doors with overlapping in the door closing position door leaf and door frame profiles, since the pivoting movement is to be designed by the shape of the guide recesses so that the door first lifts in the thickness direction of the Übehappungsbereich before it is rotated.

The first and the second hinge bracket fulfill different functions. The connection of the two receiving bodies through the first hinge bracket forms a double joint which could freely move about the first and second vertical axes of rotation in a space of movement with two degrees of freedom, if the second hinge bracket were not provided. By the second hinge bracket and the shape of the guide recesses of the receiving body of the motion sequence is determined kinematically within the movement space. It is understood that the shape of the guide recesses of a receiving body is to be adapted to the shape of the guide recesses of the other receiving body.

With the door hinge according to the invention can be achieved without further opening angle up to 180 degrees, the pivoting movement is divided into a sequence of different movements.

Between the first and the second pivoting region, an intermediate region of at most 60 degrees is preferably provided, in which both ends of the second hinge strap slide simultaneously in the associated guide recesses. Such an intermediate area can be realized in that in the sections of the guide recesses in which the ends of the second hinge bracket slide simultaneously in the intermediate region, the directions of curvature change along the tracks of the sliding ends, whereby the course of the guide recesses consequently has a point of inflection. In such an S-shaped course, the end of the second hinge bracket, which is associated with the receiving body with the first vertical axis of rotation slides to the end of the guide recess in which it is guided and strikes there, the other end of the second hinge bracket leaves a stop position and slides in the associated guide recesses of the other receiving body.

Preferably, in the embodiments described above, the first vertical axis of rotation is assigned to the door frame side receiving body. So pivots the first hinge bracket in a first pivoting area about the first vertical axis of rotation, the door is lifted during the first pivoting range of the door frame, without turning relative to the first hinge bracket.

According to a preferred embodiment of the invention, the turzargenseitigen receiving body associated vertical axis of rotation with respect to the center of the door frame is moved in the thickness direction, in the direction in which the door swings open. Additionally or alternatively, the vertical axis of rotation associated with the door leaf-side receiving body may be displaced in the thickness direction with respect to the center of the door leaf, in the direction in which the door leaf swings open. By positioning the first and the second vertical axis of rotation of the spatial course of the pivot point is determined based on the door frame and the door leaf. A displacement of the axes of rotation in the direction in which the door swings open, on the one hand ensures that in a door with an opening angle of 180 degrees open a gap between the door frame and Door leaf forms and on the other hand, that the fulcrum in the entire pivoting movement is far enough away from the door frame to prevent jamming of the door leaf and door frame.

In a preferred embodiment of the invention, the receiving body each consist of a receiving part and adjustable inserts, wherein the inserts each have a guide recess and a receptacle for a vertical axis of rotation of the first hinge bracket. The inserts can be designed such that the position of the door leaf in the vertical direction (Z), in the horizontal thickness direction (Y) and / or parallel to the horizontal orientation of the closed door leaf (X) with respect to the door frame is adjustable by the adjustment of the inserts.

In order to ensure the lasting functioning of the door hinge, measures can be taken to reduce wear due to friction. As part of these measures, the second hinge bracket can be slidably and rotatably mounted on sliding pins in the guide recesses, wherein the material A, which surrounds the sliding pins in the region of the guide recesses, differs from the surface material B of the sliding pins. By a suitable combination of materials A-B wear by friction can be reduced.

In the context of the invention, different designs of the hinge bracket, which are preferably designed as castings made of plastic or metal, can be realized. In a preferred embodiment of the invention, one of the hinge bracket H-shaped and the other hinge bracket is fork-shaped, wherein the H-shaped hinge bracket is disposed with its central portion between the two fork arms of the other fork-shaped hinge bracket and wherein the fork arms of the other hinge bracket at a their ends through a vertical section are connected. The H-shaped hinge bracket is pivotally connected at its central portion about a vertical connecting axis with the fork arms of the other, forked hinge bracket.

According to another, likewise advantageous embodiment of the invention, the first hinge bracket and the second hinge bracket are designed as identical connecting elements and have a U-shape, each with a horizontally extending connecting web and vertically aligned legs. Both hinge brackets are assembled in the manner of a plug connection and rotatably connected to the connecting webs.

Preferably, the hinge straps extend in the vertical direction in the areas in which they are mounted in the receiving bodies, zoom up to the receiving body. Such an embodiment of the hinge bracket, which is also possible in particular in the previously described embodiments of the hinge bracket, allows the hinge bracket to be mounted on short pins, without a larger clearance having to be bridged between the hinge straps and receiving bodies. By such an embodiment, a high dimensional stability and a very low clearance of the door hinge can be achieved.
