It has long been known to provide wristbands with a locking direction, which holds the wristbands in a particular open or closed position, so that they can be pivoted out of this position only with increased effort. For example, the
FR 2 408 711 A1 Such a hinge, in which a displaceable in the direction of the hinge axis locking body acts on a guide body with upwardly directed control surface. The guide body is fixedly arranged on the wall-side hinge part, so that the locking positions of the hinge can not vary. The guide body has two latching recesses at the two ends of its guide surface and a central latching recess, which is formed by the lower vertex of the guide surface. The oblique surfaces laterally of the lower vertex form the control surfaces along which the locking body is pressed due to the spring force in the middle recess. But also the lateral recesses have short control surfaces, which cause the latching body after exceeding one of the upper vertexes of the guide surface rolls into the latching recess. A second catch body can roll on a complementary, downwardly facing guide surface of the guide body, so that the guiding and locking force is increased.
-
Wristbands in which the guide body is rotatably mounted about the hinge axis, are in the
CH 535 887 A , of the
US 5 079 798 A and the
EP 0 599 255 A1 disclosed. In these hinge bands, however, no pronounced control surfaces are provided, which cause the retraction of the locking body in the recesses over a longer angle of rotation of the hinge. Only the sides of the lowest points of the recesses recesses serve as a short control surface and cause a sliding in of the locking body in the recess and thus pivoting the door in its rest position.

CH 376 389 A a door hinge is known, which has a first band part in the form of a sleeve body and which has a second band part in the form of a lower carrier. The first band part and the second band part are hinged together about a hinge pin formed as a hinge axis. Within the door hinge is a locking device, which consists of a in the first band part against the action of a spring movably guided detent body and a second band part associated latching recess which is formed on the hinge axis. The locking body engages in the locking position resiliently in the recess, which is arranged on the hinge axis.
