Abstract
Abstract A readily removable closure panel for an opening in a roof or wall of a vehicle and including a quick release hinge means for permitting partial opening of the panel and for rapid disengagement and removal of the panel from the roof. An adjustable hinge construction for a panel wherein the hinge construction includes a resilient yieldable hinge member which provides a hinge edge for releasable pivotal engagement with a cooperable frame portion of a frame member defining an opening in the roof. The hinge edge engagement provides a hinge axis beneath or interiorly of the panel margin and the hinge edge is adjustably spaced therefrom for causing the panel edge margin to press against a resilient gasket on the frame member in both closed and partially opened position of the panel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
142 words
A hinge construction for a panel serving as a removable closure for an opening defined by a frame having support surfaces for edge margins of said panel and resilient compressible gasket means between said edge margins and said support surfaces, comprising in combination: means providing a recess on said frame defined by a downwardly directed lip beneath said support surfaces; a securement means extending through the panel edge margins in lateral spaced relation to said recess means; leaf spring means carried by said securement means and having a spring edge portion receivable in said recess for hinging relation therewith in one position; and means adjustable on said securement means and adapted to contact said spring means for moving said spring means into said hinged relation with said recess means in said one position and for releasing said spring means in another position.
Claim 2
Dependent Claim
142 words
A hinge construction for a panel serving as a removable closure for an opening defined by a frame having support surfaces for edge margins of said panel and resilient compressible gasket means between said edge margins and said support surfaces, comprising in combination: means providing a recess on said frame defined by a downwardly directed lip beneath said support surfaces; a securement means extending through the panel edge margins in lateral spaced relation to said recess means; leaf spring means carried by said securement means and having a spring edge portion receivable in said recess for hinging relation therewith in one position; and means adjustable on said securement means and adapted to contact said spring means for moving said spring means into said hinged relation with said recess means in said one position and for releasing said spring means in another position.
Claim 3
Dependent Claim
33 words
A hinge construction as stated in claim 1 wherein said securement means includes a bolt having a threaded portion, and said adjustable means includes a nut means threaded on said bolt threaded portion.
Claim 4
Dependent Claim
34 words
A hinge construction as stated in claim 2 wherein said nut means is provided with a cam member pivotally mounted thereon for camming said leaf spring means into hinging relation with said recess means.
Claim 5
Dependent Claim
19 words
A hinge construction as stated in claim 1 wherein said spring edge portion includes a hook shaped hinge section.
Claim 6
Dependent Claim
45 words
A hinge construction as stated in claim 1 wherein said spring means is a folded leaf spring member having leaf spring elements extending alongside each other; one of said leaf spring elements having a configuration cooperable with said securement means for orienting said spring means.
Claim 7
Dependent Claim
50 words
A hinge construction as stated in claim 5 wherein the other of said leaf spring elements is provided with said spring edge portion; said leaf spring means being maintained under compression by said adjustable means for retaining said hinging relation and for compressing said gasket means by panel edge margins.
Claim 8
Dependent Claim
35 words
A hinge construction as stated in claim 5 wherein said other leaf spring element is provided with longitudinally extending ribs for restricting flexure of said leaf spring element along a major portion of its length.
Claim 9
Dependent Claim
43 words
A hinge construction as stated in claim 1 wherein said adjustable means includes a cam member pivotally mounted thereon for engagement with said other of said leaf spring elements for stressing said leaf spring means to maintain hinge relationship with said recess means.
Claim 10
Dependent Claim
39 words
A hinge construction as stated in claim 8 wherein said pivotally mounted cam member on said adjustable means is movable into a position to release said leaf spring element from its stressed condition and to release said hinged relation.
