Abstract
Abstract A sheet clamp means clamps the vertical edge of a bathtub shower curtain adjacent a wall to provide an effective seal. The clamp means includes a camming means which applies forces to rotate pins carrying a swinging clamp plate. Both gravity-actuated and force-actuated sheet clamps are shown.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
129 words
A sheet-clamping assembly for clamping the edge of a sheet which extends in a first direction, comprising, in combination: a first elongated member having a first clamping surface extending in said first direction; a second elongated member having a second clamping surface extending in said first direction; a plurality of pivot connections between said first and second members to allow relative pivotal movement between said members and thereby to allow relative movement between said first and second clamping members to grip said edge of said sheet between said first and second clamping surfaces, at least one of said pivot connections comprising means responsive to translation of one of said members relative to the other of said members in said first direction for pivoting said members relative to each other.
Claim 2
Dependent Claim
129 words
A sheet-clamping assembly for clamping the edge of a sheet which extends in a first direction, comprising, in combination: a first elongated member having a first clamping surface extending in said first direction; a second elongated member having a second clamping surface extending in said first direction; a plurality of pivot connections between said first and second members to allow relative pivotal movement between said members and thereby to allow relative movement between said first and second clamping members to grip said edge of said sheet between said first and second clamping surfaces, at least one of said pivot connections comprising means responsive to translation of one of said members relative to the other of said members in said first direction for pivoting said members relative to each other.
Claim 3
Dependent Claim
61 words
An assembly according to claim 1 in which said one of said pivot connections comprises a pin means having one end rigidly affixed to said first elongated member and slot means provided in said second elongated member, said slot means extending at an acute angle to said first direction and being adapted to retain the other end of said pin means.
Claim 4
Dependent Claim
73 words
An assembly according to claim 2 in which said slot means includes a pair of edges adapted to engage said pin means at different distances from said other end of said pin means, said pair of edges extending at mutually differently varying acute angles to said first direction, whereby translation of said pin means along said slot means causes rotation of said means about a succession of axes parallEl to said first direction.
Claim 5
Dependent Claim
39 words
An assembly according to claim 1 wherein said first direction is substantially vertical and one of said members is fixed stationary, whereby gravity causes vertical translation of said one of said members relative to said other of said members.
Claim 6
Dependent Claim
41 words
An assembly according to claim 1 wherein said first direction is substantially horizontal and said assembly includes means acting between said first and second members for causing translation of said one of said members relative to said other of said members.
