Abstract
Door hinge with a locking device based on a field force, including a cylinder divided by a piston into working spaces that are filled with an operating medium whose viscosity can be changed by means of a field force. The working spaces are connected to one another by at least one flow connection that is subject to the influence of a field force generating element. The door hinge is designed as a pivot bearing, wherein the cylinder takes the form of a bearing eye and the piston takes the form of a rotary piston with at least one blade.
Claims7
A pivot bearing door hinge with a locking device based on a field force, comprising:
- a cylinder in the form of a pivot eye of said hinge;
- a rotary piston with at least one blade which divides the cylinder interior into at least two working spaces;
- a field force generating element arranged concentrically to the cylinder, said field force generating element comprising a ring segment located radially outside the cylinder and having a circumferential extent to cover only a first rotation angle range of the rotary piston;
- said working spaces being filled with an operating medium whose viscosity can be changed by means of a field force and being connected to one another by at least one flow connection that is subject to the influence of said field force generating element;
- and
- said at least one flow connection takes the form of a gap between said at least one blade and the inner wall of the cylinder.
