Abstract
Abstract A holder for the convenient dispensing of rolled paperr towels and the like. A standard of size to closely engage the interior of the tube core for the roll of paper extends outwardly from a base support that is adapted for engagement with various support surfaces disposed near points of use for the towels. The hollow base has widely spaced apart sidewalls that enclose a centrally disposed suction cup with edges of said sidewall being selectively held in contact with the support surface by vacuum influences induced by said suction cup to provide stability for said holder, its standard and any roll of paper towels disposed thereon. A mechanism on said standard that is interconnected to said suction cup induces or relieves the vacuum influences when the holder is being placed or removed. The holder is intended primarily for use with the base disposed on horizontal surfaces and the standard and roll of paper towels in upright position with adequate support being provided by said base and suction cup so the tearing of individual towels from the roll is a single-handed operation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
239 words
A holder for tube core types of roll paper towels adapted for selective positioning and mounting on a flat support surface adjacent user work stations comprising a base element having planar contact surfaces for engaging said support surface at widely spaced apart positions, a standard disposed in normal position with respect to said base and of exterior size for close engagement with the interior of said tube core whereby relative rotation as between said tube core and said standard is frictionally resisted, said base providing a recess therein intermediate opposed contact surfaces of said base, a suction cup within said recess having its outer edges disposed in planar positions with respect to the contact surfaces of said base and, accordingly, in position for contact with said support surface, said suction cup further being isolated and free of major torsion forces that may be exerted by and on said base and standard, actuator means on said standard inclusive of an output element providing translational relative motion with respect to said base and suction cup and, accordingly, directed toward and away from said support surface, and connector means for the transmission of tension loadings joining the said output element for said actuator means and said suction cup whereby vacuum influences are relieved and induced beneath said suction cup for selectively holding the suction cup and, accordingly, said holder and the contact surfaces thereof securely on said support surface at adjusted positions.
Claim 2
Dependent Claim
239 words
A holder for tube core types of roll paper towels adapted for selective positioning and mounting on a flat support surface adjacent user work stations comprising a base element having planar contact surfaces for engaging said support surface at widely spaced apart positions, a standard disposed in normal position with respect to said base and of exterior size for close engagement with the interior of said tube core whereby relative rotation as between said tube core and said standard is frictionally resisted, said base providing a recess therein intermediate opposed contact surfaces of said base, a suction cup within said recess having its outer edges disposed in planar positions with respect to the contact surfaces of said base and, accordingly, in position for contact with said support surface, said suction cup further being isolated and free of major torsion forces that may be exerted by and on said base and standard, actuator means on said standard inclusive of an output element providing translational relative motion with respect to said base and suction cup and, accordingly, directed toward and away from said support surface, and connector means for the transmission of tension loadings joining the said output element for said actuator means and said suction cup whereby vacuum influences are relieved and induced beneath said suction cup for selectively holding the suction cup and, accordingly, said holder and the contact surfaces thereof securely on said support surface at adjusted positions.
Claim 3
Dependent Claim
57 words
The paper towel holder as set forth in claim 1 wherein said base and standard are formed unitarily with said base recess being disposed centrally thereof and further comprising a central ring structure within said recess and extending toward the outer edges of said suction cup for holding the cup edges in contact with said support surface.
Claim 4
Dependent Claim
45 words
The paper towel holder as set forth in calim 2 and further comprising a structurally separate suction cup support piece intermediate said cup and said central ring structure for holding the outer edges of the suction cup in contact with said towel holder support surface.
Claim 5
Dependent Claim
45 words
The paper towel holder as set forth in calim 2 and further comprising a structurally separate suction cup support piece intermediate said cup and said central ring structure for holding the outer edges of the suction cup in contact with said towel holder support surface.
Claim 6
Dependent Claim
49 words
The paper towel holder as set forth in claim 1 wherein said base and standard are hollow with the output element of said actuator means and said connector means being disposed interiorly of said standard and with said connector means further transmitting only tension loadings to said suction cup.
Claim 7
Dependent Claim
42 words
The paper towel holder as set forth in claim 4 wherein said actuator means is disposed at the top of said standard and further comprising an inclined plane element providing the translational relative motion for the output element of said actuator means.
Claim 8
Dependent Claim
53 words
The paper towel holder as set forth in claim 5 wherein said actuator means is an operator cap rotatably mounted on said standard with said inclined plane element being disposed operatively between said cap and said standard whereby the cap and the output element are moved reciprocally toward and away from said base.
Claim 9
Dependent Claim
39 words
The paper towel holder as set forth in claim 6 wherein said inclined plane element includes mating cam surfaces disposed circumferentially on said cap and standard and further comprising stop members for limiting rotary movement operations of said cap.
Claim 10
Dependent Claim
61 words
The paper towel holder as set forth in claim 7 wherein the output element of said actuator means is a tab depending centrally from said cap and wherein said connector means comprises an operator rod extending from said tab, and hook ends on said rod for loose engagement to provide limited rotary freedom of motion for said operator rod and cap.
Claim 11
Dependent Claim
18 words
The paper towel holder as set forth in claim 7 wherein said connector means is of multi-link construction.
