Electronic residential tissue dispenser
First Claim
1. An automatic electronic dispenser for dispensing a roll of paper product, comprising:
- a dispenser module for driving paper from the roll through a discharge chute at the bottom of the module, the dispenser module including;
a paper roll holder attached to the sides of the dispenser module;
a driving roller for unrolling the paper from the paper roll holder in response to a signal from an electronic sensor; and
a frame at least partially supporting a plurality of independent rotatable pressing rollers, the frame connected to one or more biasing members that urge each of the plurality of pressing rollers toward engagement with the driving roller to engage the paper therebetween for dispensing the paper along a path between the pressing and driving rollers to a discharge chute, wherein the pressing rollers are mounted to the frame along a common pivot axis so that one of the pressing rollers is moved toward closer engagement with the driving roller as another one of the pressing rollers is moved away from the driving roller.

Abstract
An automatic electronic dispenser for dispensing a roll of paper product. A dispenser module drives paper from the roll through a discharge chute at the bottom of the module. A front cover hinged on each side rotates to an open position for loading a paper roll. A back cover enables mounting the electronic dispenser to a vertical surface such as a wall. A paper roll holder is attached to the sides of the dispenser module. A driving roller unrolls the paper from the paper holder in response to a signal from an electronic sensor. A plurality of pressing rollers engages the driving roller as paper is being dispensed along a path between the pressing and driving rollers to a discharge chute.

13. An automatic electronic dispenser for dispensing a roll of tissue paper from the roll through a discharge chute, comprising:
-
a paper roll holder attached to the sides of the dispenser; a driving roller for unrolling the paper from the paper holder in response to a signal from an electronic sensor; and a pair of pressing rollers pivotally mounted in a parallel stacked arrangement defining a substantially unitary structure that is pivotable about a common axis, each of the pressing rollers arranged adjacent the driving roller and engaging the driving roller in biased engagement so as to feed the paper along a path between the pressing and driving rollers and therewith through the discharge chute; wherein the pair of pressing rollers are pivotable together about the common axis such that as one of the pressing rollers is pivoted away from the driving roller, another one of the pressing rollers is pivoted toward the driving roller. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. An automatic electronic dispenser for dispensing a roll of tissue paper, comprising:
-
a dispenser module for driving tissue from the roll through a discharge chute at the bottom of the module, the dispenser module having a front portion that is pivotable about a hinge, the dispenser module including; a paper roll holder attached to the sides of the dispenser module; a driving roller for unrolling the tissue from the paper holder in response to a signal from an electronic sensor; and a plurality of pressing rollers including an upper pressing roller and a lower pressing roller mounted in a vertically stacked, parallel configuration and pivotable as a substantially unitary structure about a common axis, the pressing rollers each frictionally contacting the driving roller so as to rotate therewith to dispense the tissue along a path between the pressing and driving rollers to the discharge chute, and wherein as the substantially unitary structure rotates about the common axis, the lower roll is pivoted away from the driving roller, and the upper pressing roll is pivoted into closer frictional contact with the driving roller. - View Dependent Claims (22, 23, 24, 25, 26, 27)

28. An intelligent dispensing system for automatically dispensing and monitoring usage of a paper product, comprising:
-
a plurality of dispensers, each dispenser having a dispenser module for driving paper from a roll of the paper product through a discharge chute, the dispenser module including; a driving roller for unrolling the paper from a paper roll holder in response to a signal from an electronic sensor; and a plurality of pressing rollers, the pressing rollers engaging the driving roller so as to engage the paper therebetween for dispensing the paper along a path between the pressing and driving rollers to a discharge chute, wherein the pressing rollers are independently rotatable and are mounted for common rotation about a pivot axis such that one of the pressing rollers to moves toward tighter engagement with the driving roller as another one of the pressing rollers is moved away from the driving roller. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. A dispenser module for an automatic electronic dispenser for dispensing a roll of perforated paper mounted on a paper holder, comprising:
-
a driving roller for unrolling the perforated paper from the paper holder in response to a signal from a proximity sensor; and dual pressing rollers, including a top roller arranged above and parallel to a lower roller, the pressing rollers being substantially independently rotatable and each substantially simultaneously engaging the driving roller with the perforated paper in driven contact therebetween for dispensing the perforated paper along a path between the pressing and driving rollers to a discharge chute; wherein the dual pressing rollers are pivotally mounted for rotation about a common pivot axis, wherein the top roller is pivoted toward the driving roller as the lower roller is pivoted away from the driving roller to substantially maintain contact of the perforated paper between the driving roll and at least one of the pressing rollers. - View Dependent Claims (44, 45, 46)

47. An automatic dispenser for dispensing a roll of paper, comprising:
-
a paper holder connected to at least a portion of the automatic dispenser, the paper holder at least partially supporting the roll of paper; a driving roller that dispenses paper from the roll of paper in response to a signal from an electronic sensor; a frame arranged substantially adjacent to the driving roller; and a plurality of pressing rollers connected to the frame by one or more mounts defining a substantially unitary structure that is pivotable about an axis, and wherein the plurality of pressing rollers are disposed along the driving roller so as to at least partially define a path between the pressing rollers and the driving roller for guiding the paper toward a discharge chute, wherein the plurality of pressing rollers comprises a first pressing roller and a second pressing roller each connected to and biased by a respective biasing member, and wherein the first and second pressing rollers pivot about the axis to maintain substantially continuous contact with the paper to prevent at least partial tearing of one or more perforated portions defined in the paper.
