Abstract

The cover of a machine is supported by this hinge. It has a resilient stop which in cases of high mechanical stress, e. g., shock, serves to avoid high torsional forces, especially where covers are of an elongated shape, within the cover.

Cover Hinge

The cover of a machine is supported by this hinge. It has a resilient stop which in cases of high mechanical stress, e. g., shock, serves to avoid high torsional forces, especially where covers are of an elongated shape, within the cover.

On machine frame 1, bearing block 2 is fastened by screws 3 on both sides of the cover. Rockable cover frame 4 is supported by pins 5 of the bearing blocks, which are respectively received in guide slot 6 of the cover frame. Each of pins 5 is held by a locking lever which is rockably mounted in cover frame 4 and loaded by a spring.

When the cover is in its opened position (right-hand drawing), it abuts the machine frame at point A. If a shock is exerted on the cover in the direction of the arrow, the bearing of the cover is not rigid but pin 5 slides in guide slot 6. It thus raises locking lever 7 against the force of spring 8.

By rocking the cover frame further in the direction of the arrow, it is possible to remove the cover entirely from the hinge. This is when pin 5 slides all the way below lug 10 of the locking lever (left-hand drawing). For replacing the cover, the locking lever is raised by means of its extensions 11.
