Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
250 words
A hinge comprising: first and second hinge parts; a quadrangular link mechanism connecting said first and second hinge parts so that said first hinge part is movable with respect to said second hinge part between a closed hinge position and an open hinge position, said link mechanism including a first hinge link having a first end pivoted to said first hinge part by a first axle and a second end pivoted to said second hinge part by a second axle, and a second hinge link having a first end pivoted to said first hinge part by a third axle and a second end, said second hinge link being pivoted at a position between said first and second ends thereof to said second hinge part by a fourth axle, said second end of said second hinge link having a stop; a tipping lever pivotally mounted about said second axle, said tipping lever having thereon first and second pressure faces; and spring means, having a first end abutting said fourth axle and a second end abutting said tipping lever, for urging said tipping lever into contact with said stop, such that when said first hinge part is in said closed hinge position said first pressure face is urged against said stop and creates a torque on said second hinge link, and such that when said first hinge part is in said open hinge position, said second pressure face is urged against said stop without creating a torque on said second hinge link.
Claim 2
Dependent Claim
250 words
A hinge comprising: first and second hinge parts; a quadrangular link mechanism connecting said first and second hinge parts so that said first hinge part is movable with respect to said second hinge part between a closed hinge position and an open hinge position, said link mechanism including a first hinge link having a first end pivoted to said first hinge part by a first axle and a second end pivoted to said second hinge part by a second axle, and a second hinge link having a first end pivoted to said first hinge part by a third axle and a second end, said second hinge link being pivoted at a position between said first and second ends thereof to said second hinge part by a fourth axle, said second end of said second hinge link having a stop; a tipping lever pivotally mounted about said second axle, said tipping lever having thereon first and second pressure faces; and spring means, having a first end abutting said fourth axle and a second end abutting said tipping lever, for urging said tipping lever into contact with said stop, such that when said first hinge part is in said closed hinge position said first pressure face is urged against said stop and creates a torque on said second hinge link, and such that when said first hinge part is in said open hinge position, said second pressure face is urged against said stop without creating a torque on said second hinge link.
Claim 3
Dependent Claim

Claim 7
Dependent Claim
43 words
A hinge as claimed in claim 5, wherein said first pressure face of said stop and said first pressure face of said tipping lever are planar and are in mutual planar contact when said first hinge part is in said closed hinge position.
Claim 8
Dependent Claim
