ABSTRACT:
TECHNICAL FIELD
The present invention relates generally to a hinge, and more particularly, to a hinge for mounting a closure panel for swinging upwardly and downwardly from a normally closed configuration to an open configuration with respect to a base.
BACKGROUND ART
Hinges for opening and closing closure panels of a base are well known in the prior art. For example, in the automotive environment closure panels such as trunk lids have utilized gooseneck hoop-type hinges. Conventional gooseneck hoop-type hinges have protruding hoops that extend down into the cargo area when the trunk lid is closed and limit useable cargo space. The gooseneck hoop of these hinges are required to enable the closure panel, or trunk lid, of the automobile to move or rotate clear of the vehicle body while allowing for maximum access to the trunk compartment. The intrusion of the gooseneck hoop arms takes up considerable cargo area space thus reducing the capacity of the trunk area.
SUMMARY OF THE INVENTION
Accordingly, it is an objective of the present invention to provide a hinge which is self contained, having no movable parts extending below the hinge's base member bracket.
It is a further object of the present invention to provide a hinge for moving the closure panel of a base sufficiently clear of the base (in excess of 90 degrees) so as to allow for the greatest amount of access to the area below the closure panel.
It is still a further object of the present invention to provide a hinge which may be modified to fit a specific closure panel and base.
In carrying out the above objects and other objects and features of the present invention, a hinge for upwardly moving and rotating the closure panel of a base is provided to improve access and utilization of the area covered by the closure panel. The hinge includes two brackets, a closure panel bracket mountable to the closure panel and a base member bracket mountable to the base. A cooperative tripartite set of links are disposed between the brackets and are operatively connected to a biasing member. The biasing member urges the links to upwardly translate and rotate the closure panel bracket from the base member bracket.
The set of links include a biasing link, an intermediate link, and an anchoring link. The biasing link has a driving end pivotally connected to the biasing member and a driven end pivotally connected to the driving end of the intermediate link and to a major axis of the closure panel bracket. The intermediate link has a fixed driven end pivotally mounted to the base member bracket and a driving end rotatably mounted to the closure panel bracket and the driven end of the biasing link. The anchoring link has a driving end pivotally connected to the closure panel bracket and a fixed driven end being rotatably mounted to the base member bracket. The link set is adapted for cooperative movement so as to facilitate an upward rotational and translational progression of the closure panel in relation to the base.
The advantages accruing to the present invention are many. The present invention being self contained does not intrude upon the area below the closure panel. The hinge contains no movable parts which extend below the hinge's base member bracket. Thus, the area below the closure panel is maximized. Additionally, the present invention allows the closure panel of a base to be moved clear (in excess of 90 degrees) of the base, allowing for greater access to the area covered by the closure panel.
The above objects and other objects, features, and advantages of the present invention will be readily appreciated by one of ordinary skill in the art from the following detailed description of the best mode for carrying out the invention when taken in connection with the accompanying drawings.
