Abstract
Abstract A quick-release-hinge device comprising an elongated, latching, tongue member being releasably mounted to a stationary mounting bolt secured along one edge of a removable cover member, the cover member being formed to close an opening in a structure wherein the opening is defined by a peripheral frame member which includes a jaw member arranged to releasably receive the hinged, latching, tongue member, and a peripherally mounted sealing member disposed to be positioned between the frame member and the cover member in order to sealingly engage the peripheral edge of the cover in a closed mode. The elongated tongue is releasably held in a substantially fixed relationship to the cover member by a hold-down handle when the cover is closed or pivoted about the jaw member. When the cover member is to be removed from the frame structure, the hold-down handle is disengaged from the tongue member, allowing the tongue to float freely and to separate from the cover -- thus permitting the tongue member to have space for disconnecting from the jaw member, and thereby releasing the cover from the frame structure.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
113 words
A quick-release-hinge device arranged to be connected between a fixed-frame structure and a movable-closure member, wherein the frame structure includes a peripheral sealing mold and wherein the hinge device comprises: a fixed-hinge member carried by said frame structure; a releasable-hinge member releasably mounted to said closure member and releasably attached to said fixed-hinge member; fastener means mounted to said closure member to support said releasable-hinge member in both a stationary and a movable position; means for releasably clamping said releasable-hinge member in a locked stationary position relative to said closure member; and stop means mounted on said releasable-hinge member whereby said hinge member is restricted in its movement when in a movable position.
Claim 2
Dependent Claim
113 words
A quick-release-hinge device arranged to be connected between a fixed-frame structure and a movable-closure member, wherein the frame structure includes a peripheral sealing mold and wherein the hinge device comprises: a fixed-hinge member carried by said frame structure; a releasable-hinge member releasably mounted to said closure member and releasably attached to said fixed-hinge member; fastener means mounted to said closure member to support said releasable-hinge member in both a stationary and a movable position; means for releasably clamping said releasable-hinge member in a locked stationary position relative to said closure member; and stop means mounted on said releasable-hinge member whereby said hinge member is restricted in its movement when in a movable position.
Claim 3
Dependent Claim
49 words
A quick-release-hinge device as recited in claim 1, wherein said releasable-clamping means comprises: a movable-handle member operably connected to said fastener means; a cam means formed on said handle member, causing said handle to engage said releasable-hinge member; and connecting means connecting said movable-handle member to said fastener means.
Claim 4
Dependent Claim
83 words
A quick-release-hinge device as recited in claim 2, wherein said movable handle comprises an elongated-arm member having one end thereof rotatably attached to said connecting means; and wherein said cam means comprises at least one cam head positioned adjacent said releasable-hinge member, whereby said releasable-hinge member can be released from a fixed position to a floating position so as to be disconnected from said fixed-hinge member carried by said frame structure, thereby permitting said closure member to be removed from said frame structure.
Claim 5
Dependent Claim
76 words
A quick-release-hinge device as recited in claim 1, wherein said releasable hinge member comprises an elongated tongue member having disposed at one end thereof an elongated aperture arranged to be supported in a nonrotatable manner on said fastener means, and including a transversely arranged slot disposed in the end opposite said elongated aperture; and wherein said fixed hinge member comprises a jaw member adapted to be removably received in said transverse slot of said tongue member.
Claim 6
Dependent Claim
83 words
A quick-release-hinge device as recited in claim 4, wherein said releasable clamping means comprises: a movable elongated arm member having a free end, the opposite end thereof being rotatably attached to said fastener means; and a cam head formed on the attached end of said elongated arm member for engagement with said tongue member, whereby said tongue member is releasably locked into a stationary position relative to said closure member, in order to permit said closure member to pivot about said hinge members.
Claim 7
Dependent Claim
40 words
A quick-release-hinge device as recited in claim 5, wherein said fastener means comprises: a nut-head member supported in said closure means; a connecting means carried by said nut-head member; and means for securing said nut head to said closure means.
Claim 8
Dependent Claim
43 words
A quick-release-hinge device as recited in claim 6, wherein said connecting means comprises: a depending eyelet lug having a bore disposed therein; and a pin member received in said bore of said eyelet to operably connect said arm member to said eyelet lug.
Claim 9
Dependent Claim
26 words
A quick-release-hinge device as recited in claim 7, wherein said fastener means includes a ring member disposed between said closure member and said releasable arm member.
Claim 10
Dependent Claim
33 words
A quick-release hing device as recited in claim 8, wherein said ring member comprises an annular nut having a depending boss adapted to be received in said elongated opening of said tongue member.
Claim 11
Dependent Claim
69 words
A quick-release-hinge device as recited in claim 2, wherein said cam means comprises: a pair of depending cam members having centrally located detents formed therein; and a keeper head secured to said fastener means; said keeper head including a pair of cam ear members arranged to engage said depending cam members and be removably received in said detents, whereby said handle is releasably engaged with said releasable hinge member.
Claim 12
Dependent Claim
51 words
A quick-release-hinge device as recited in claim 2, wherein said cam means comprises a bellville washer interposed between said handle and said releasable-hinge member; and wherein said connecting means comprises a threaded lug member having a stop member affixed thereto for preventing said handle from being separated from said lug member.
Claim 13
Dependent Claim
36 words
A quick-release-hinge device as recited in claim 2, wherein said stop means comprises a resilient-bumper member affixed to said releasable-hinge member so as to engage said movable-closure member, limiting the upward movement of said releasable-hinge memeber.
Claim 14
Dependent Claim
43 words
A quick-release-hinge device as recited in claim 2, wherein said stop means comprises a flexible, leaf-spring member mounted on said releasable hinge member to provide a downward tension on said hinge member so as to control the upward movement of said hinge member.
