ABSTRACT:
TECHNICAL FIELD
This invention relates to slow-opening hinged doors, and particularly to compartment doors, such as used for glove compartments in automobiles which have hinged doors that may tilt with the compartment to expose or open its interior.
DISCUSSION OF THE PRIOR ART
It is desirable to enhance the quality of a glove box door operation to have a slow or controlled rate of door opening. Controlled rate hinges have heretofore proven to be too expensive or heavy to be suitable for the light touch and feel that is required by modern automotive customers.
SUMMARY OF THE INVENTION
This invention provides a less expensive and simpler way to control movement of automotive glove box doors. To this end, the invention is an assembly having a variable friction regulated hinged door that comprises: first and second hinged leafs movable about a common axis, the first hinge leaf having an integral plastic camming surface positioned eccentrically about the common axis, the second hinged leaf having an integral plastic cam follower surface positioned about the common axis to engage the camming surface with increasing friction as the camming surface is cammed against the follower; and means for increasing the frictional engagement between the camming surface and the cam follower surface in response to weight added to either of said hinged leafs to control the rate at which the leafs rotate relative to each other.
