Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 158 words
A copyholder comprising: a support unit including a support surface and a bottom ledge connected generally orthogonally thereto; a clamp assembly including an immovable jaw, and a movable jaw coacting therewith; a flexible riser connecting the clamp assembly to the support unit; and means for interconnecting the flexible riser to the clamp assembly comprising a base pivot connected to the flexible riser, and a base pivot holder connected to the clamp assembly; said base pivot receivable within a bore in the base pivot holder and vertically captured thereby for pivotal motion relative thereto, so as to permit pivotal motion of the clamp assembly relative to the flexible riser; wherein the base pivot comprises a first portion and a second portion axially connected to the first portion and having a diameter less than that of the first portion, and the base pivot holder's bore is a stepped through-bore sized and configured so as to receive therein said base pivot.
Claim 2
Dependent Claim 158 words
A copyholder comprising: a support unit including a support surface and a bottom ledge connected generally orthogonally thereto; a clamp assembly including an immovable jaw, and a movable jaw coacting therewith; a flexible riser connecting the clamp assembly to the support unit; and means for interconnecting the flexible riser to the clamp assembly comprising a base pivot connected to the flexible riser, and a base pivot holder connected to the clamp assembly; said base pivot receivable within a bore in the base pivot holder and vertically captured thereby for pivotal motion relative thereto, so as to permit pivotal motion of the clamp assembly relative to the flexible riser; wherein the base pivot comprises a first portion and a second portion axially connected to the first portion and having a diameter less than that of the first portion, and the base pivot holder's bore is a stepped through-bore sized and configured so as to receive therein said base pivot.
Claim 3
Dependent Claim 41 words
The copyholder of claim 1 further including means for interconnecting the support unit to the flexible riser, including a pivot block attachable to the support unit, a knuckleholder attachable to the flexible riser, said knuckleholder pivotally connected to the pivot block.
Claim 4
Dependent Claim 24 words
The copyholder of claim 2 wherein the interconnection means further includes a shoulder screw threadily engaging the knuckleholder and disposed within the pivot block.
Claim 5
Dependent Claim 50 words
The copyholder of claim 1 wherein said base pivot holder is releasably, fixedly secured to said clamp assembly and said base pivot is threadedly secured to the flexible riser and disposed such that its first portion is positioned between the clamp assembly and a portion of the base pivot holder.
Claim 6
Dependent Claim 24 words
The copyholder of claim 1 wherein the bottom ledge has a channel sized and configured to receive an edge of the support unit therein.
Claim 7
Dependent Claim 19 words
The copyholder of claim 5 wherein the support unit is maintained within the channel by a plurality of screws.
Claim 8
Dependent Claim 14 words
The copyholder of claim 5 wherein the bottom ledge has a textured top surface.
Claim 9
Dependent Claim 14 words
The copyholder of claim 5 wherein the bottom ledge has top surface with serrations.
Claim 10
Dependent Claim 13 words
The copyholder of claim 1 wherein the support unit is made of plexi-glass.
Claim 11
Dependent Claim 22 words
The copyholder of claim 1 wherein the flexible riser includes a flexible tube and a bellows tube extending over the flexible tube.
Claim 12
Dependent Claim 21 words
The copyholder of claim 10 wherein the bellows tube is made of plastic and the flexible tube is made of metal.
Claim 13
Dependent Claim 20 words
The copyholder of claim 2 wherein the pivot block includes an inclined surface to which the support unit is attached.
Claim 14
Dependent Claim 309 words
A copyholder comprising: (a) a support unit including a support surface, a bottom ledge connected generally orthogonally thereto, said bottom ledge having a channel sized and configured to receive an edge of the support surface therein, and a connecting portion connected to the bottom ledge; (b) a clamp assembly including an immovable jaw and a movable jaw coating therewith; (c) a flexible riser pivotally connected to the clamp assembly and the support unit, said flexible riser being bendable so as to permit manual placement of the support unit; (d) means for interconnecting the support unit and the flexible riser, including a knuckleholder threadedly engaging a first end of the flexible riser, a pivot block fixedly secured to the connecting portion of the support unit, and means for pivotally connecting the pivot block to the knuckleholder including a shoulder screw received through a through-bore in the pivot block into threaded engagement with a threaded hole in the knuckleholder, wherein said pivot block can rotate about a shoulder portion of the shoulder screw thereby permitting pivotal motion of the support unit relative to the flexible riser; and (e) means for interconnecting the flexible riser and the clamp assembly, including a base pivot comprising a first portion and a second portion axially connected to the first portion and having a diameter less than that of the first portion, a base pivot holder comprising a through-bore sized and configured so as to receive therein said base pivot, said base pivot holder fixedly secured to said clamp assembly, said base pivot threadedly secured to a second end of the flexible riser and captured vertically while rotatably disposed within the base pivot holder such that its first portion is positioned between the immovaable jaw and a portion of the base pivot holder, thereby permitting pivotal motion of the clamp assembly relative to the flexible riser.
Claim 15
Dependent Claim 309 words
A copyholder comprising: (a) a support unit including a support surface, a bottom ledge connected generally orthogonally thereto, said bottom ledge having a channel sized and configured to receive an edge of the support surface therein, and a connecting portion connected to the bottom ledge; (b) a clamp assembly including an immovable jaw and a movable jaw coating therewith; (c) a flexible riser pivotally connected to the clamp assembly and the support unit, said flexible riser being bendable so as to permit manual placement of the support unit; (d) means for interconnecting the support unit and the flexible riser, including a knuckleholder threadedly engaging a first end of the flexible riser, a pivot block fixedly secured to the connecting portion of the support unit, and means for pivotally connecting the pivot block to the knuckleholder including a shoulder screw received through a through-bore in the pivot block into threaded engagement with a threaded hole in the knuckleholder, wherein said pivot block can rotate about a shoulder portion of the shoulder screw thereby permitting pivotal motion of the support unit relative to the flexible riser; and (e) means for interconnecting the flexible riser and the clamp assembly, including a base pivot comprising a first portion and a second portion axially connected to the first portion and having a diameter less than that of the first portion, a base pivot holder comprising a through-bore sized and configured so as to receive therein said base pivot, said base pivot holder fixedly secured to said clamp assembly, said base pivot threadedly secured to a second end of the flexible riser and captured vertically while rotatably disposed within the base pivot holder such that its first portion is positioned between the immovaable jaw and a portion of the base pivot holder, thereby permitting pivotal motion of the clamp assembly relative to the flexible riser.
