Patent ID: 7699378

Claim:
A vehicle comprising: a body having an opening; a closure member for closing the opening, the closure member being pivotally mounted to the body at the opening for movement about a generally horizontal pivot axis between a raised position and a lowered position; a pair of hinge mechanisms on opposing sides of the closure member, the hinge mechanisms pivotally mounting the closure member for the movement about the pivot axis and permitting removal of the closure member from the body; wherein at least one of the pair of hinge mechanisms comprises: a housing fixedly connected to one of the body and the closure member and a connection part fixedly connected to the other of the body and the closure member; a first cam and a second cam, the first and second cams each having a sloped engagement surface; the first and second cams being provided within the housing along the pivot axis, with the first cam being mounted for enabling relative pivotal movement between the first cam and the housing and the second cam being fixed against pivotal movement relative to the housing; the first cam and the connection part being removably connectable together to permit the removal of the closure member from the vehicle; a resilient member provided within the housing and associated with the second cam, the second cam being movable axially along the pivot axis within the housing and the resilient member biasing the second cam towards the first cam; the sloped engagement surfaces of the first and second cams being engaged with one another under the biasing of the resilient member and configured such that relative pivotal movement between the first cam and the housing as the closure member is moved in an opening direction towards the lowered position axially displaces the second cam along the pivot axis within the housing to stress the resilient member, so that the biasing of the resilient member is translated into a force applied to the closure member in a closing direction towards the raised position.
