Description

Technical area

The present invention relates to a pendulum hinge according to the preamble of claim 1.

State of the art

A wide variety of hinges for use on swing doors and similar articulated components are known from the prior art. A hinge, which is included in the patent DE 100 66 484 B3 is described and relates to a swing door closer with torsion springs. The spring force is transmitted to the door leaf by various holding and stop devices in such a way that it can swing open on both sides and is returned to the central position.

The disadvantage here is that the torsion springs can tire and break over time when twisted by more than 90 °, and that the torque can be disproportionate to the opening angle, which results in a high restoring force when the door is fully opened and the door sashes swinging back too quickly can cause. Since three hinges are usually required in addition to the closer, the technical effort is relatively high and the hanging and unhooking of the door leaf is relatively laborious.

There are also systems with sliding blocks, where the force of a compression spring acts on an axially displaceable part and is converted into a rotary movement via a curve. Such an embodiment is described in DE 20 2018 103 378 U1 . The disadvantage of such systems can be seen in the deflection of large spring forces, which cause friction and wear. Even with a small amount of play in the mechanics, an exact return of the door leaf to the central position is no longer achieved, which must be compensated for by correspondingly strong and expensive magnets on the closing side. Here, too, hanging and unhooking the door leaf is relatively cumbersome.

From the US patent U.S. 6,635,71 A a pendulum hinge is known, which found widespread use in the well-known Western saloon doors and whose principle is still used today in swing door fittings, mainly in the furniture sector. A coil spring or several coil springs were combined with the hinge in such a way that the door closes automatically or is held open by the spring or springs when it is opened at a right angle. This pendulum hinge invention in its original form cannot be used practically everywhere, since the required flat design does not allow sufficient leverage and so an enormous spring force would be required. This would lead to correspondingly high forces, which in the case of small components exceeds the limits of what is feasible. The friction on the sliding surfaces is too high.

Presentation of the invention

The present invention is based on the object of creating a pendulum hinge which eliminates the aforementioned disadvantages and in which the functions of the hinge, return spring and central positioning are combined in one unit.

According to the invention, the above object is achieved according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous refinements and developments of the invention are specified in the dependent subclaims. The pendulum hinge according to the invention initially comprises two hinge parts for the pivotable connection of several components.

According to the invention, the pendulum hinge is characterized in that these hinge parts are pivotably connected via two axes of rotation with sliding surfaces lying against one another, with at least two spaced apart (preferably curved) receptacles for forming the sliding surfaces on the first hinge part and on to form the two axes of rotation on the first hinge part the second hinge part is provided with at least two sliding bodies corresponding to the receptacles on the first hinge part and designed to form the sliding surfaces on the second hinge part.

The two hinge parts are operatively connected to one another via at least one spring and / or damping element (preferably aligned in the longitudinal direction of the hinge parts resting against one another via the sliding surfaces), the preferred longitudinal alignment explicitly referring to the central position of the pendulum hinge, i.e. the alignment of the spring - and / or the damping element is correspondingly displaced at least in areas during a pivoting movement.

The present invention thus circumvents the problems listed in that the maximum possible levers are used directly and, in addition to the low unavoidable friction in the usual pivot bearings, almost no further friction occurs through force deflection or on sliding surfaces. Thus, the spring force acts practically directly on the Point of application of the lever. In addition, the effective torque of a door leaf, for example, can be influenced as a function of the opening angle through the arrangement of the axes of rotation, so that an almost linear torque can be achieved over a wide range, which prevents too rapid closing. Nevertheless, the torque is still relatively high shortly before reaching the middle position, so that there is no dead center that brings the door leaf to a standstill before it comes into the area of attraction of the closing magnets, which are preferably provided. The provision of at least relatively small magnets on the closing side is advantageous in order to overcome the inevitable friction of sealing brushes near the central position. In addition, the uniform torque distribution achieved by the inventive design of the pendulum hinge means that torsional vibrations of a door leaf are effectively avoided.
