Electronic residential tissue dispenser
First Claim
1. An automatic electronic dispenser for dispensing paper, comprising:
- a paper roll holder for supporting a roll of paper, the roll of paper being rotatable on or with the paper roll holder for feeding the paper therefrom and along a discharge path;
a driving roller engaging the paper and causing a length of paper to feed from the paper roll; and
a plurality of independently rotatable pressing rollers, each biased toward engagement with the driving roller sufficient to engage the paper therebetween for drawing the length of paper along its discharge path between the pressing and driving rollers and to a discharge chute, wherein the pressing rollers are mounted in a spaced arrangement adjacent the driving roller and are pivotable about a common pivot axis such 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 engaging the driving roller as paper is being dispensed along a path between the pressing and driving rollers to a discharge chute.

7. An electronic dispenser for tissue paper, comprising:
-
a housing having a discharge chute defined along a bottom portion thereof; a paper roll holder attached to the housing for supporting a roll of tissue paper; a driving roller for unrolling the tissue paper from the roll of tissue paper; and a plurality of pressing rollers, including an upper pressing roller and a lower pressing roller mounted in a substantially parallel configuration and pivotable about a common axis, wherein each of the pressing rollers is independently rotatable and frictionally contacts the driving roller so as to rotate therewith for feeding the tissue paper along a path between the pressing and driving rollers toward the discharge chute, and wherein as the upper or the lower roll is pivoted away from the driving roller, and the lower or upper pressing roll correspondingly is pivoted toward closer frictional contact with the driving roller so as to substantially maintain engagement of the tissue paper between the driving roller and at least one pressing roller sufficient to continue feeding the paper if the paper breaks between the pressing rollers. - View Dependent Claims (8, 9, 10)

11. An intelligent dispensing system for automatically dispensing and monitoring usage of a paper product, comprising:
-
a plurality of dispensers, each feeding paper from a roll of the paper product through a discharge chute, each dispenser comprising; 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 (12, 13)

14. A dispenser module for an automatic electronic dispenser for dispensing a roll of perforated paper, comprising:
-
a driving roller for driving feeding of the perforated paper 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 biased toward engaging contact with the driving roller, wherein the perforated paper is engaged 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 (15, 16, 17, 18, 19, 20, 21)
