Official abstract text for this publication.
A web material dispenser includes a housing and a pivotable roll support assembly provided therein. A first mandrel is provided at a first attachment location of the roll support assembly to support a first roll of web material. A second mandrel is provided at a second location of the roll support assembly to support a second roll of web material. The web material dispenser permits one-handed operation to replace the rolls of web material and to change positions of the mandrels within the dispenser. The roll support assembly may have a linkage arm and/or a roll support arm. Positions of the first and second mandrels relative to the dispenser's opening can be switched by pivoting the linkage arm relative to the housing and by pivoting the roll support arm relative to the linkage arm. A method for switching positions of rolls in the web material dispenser is also provided.

What is claimed is: 1. A web material dispenser comprising: a housing for housing first and a second rolls of web material, the housing comprising an opening for dispensing the web material; a roll support assembly provided in the housing, the roll support assembly comprising: a linkage arm provided with first and second attachment locations, the linkage arm being pivotally attached to the housing at the first attachment location; a roll support arm having first and second ends, the roll support arm being pivotally attached to the linkage arm at the second attachment location of the linkage arm; a first mandrel provided at the first end of the roll support arm for supporting the first roll of web material; and a second mandrel provided at the second end of the roll support arm for supporting the second roll of web material; wherein the roll support arm is selectively configurable in a first roll support dispensing position wherein the first mandrel is located below the second mandrel and a second roll support dispensing position wherein the second mandrel is located below the first mandrel, and the configuration of the roll support arm between the first and the second roll support dispensing positions is modified by pivoting the linkage arm relative to the housing and by pivoting the roll support arm relative to the linkage arm. 2. The web material dispenser of claim 1 , wherein the linkage arm is pivotally attached to the housing at a fixed location of the housing; and wherein the first and second attachment locations of the linkage arm are spaced apart and remote from one another. 3. The web material dispenser of claim 2 , wherein the linkage arm comprises a first end and a second end, opposed to the first end, the first attachment location being on the first end and the second attachment location being on the second end. 4. The web material dispenser of claim 1 , wherein the housing comprises a back-wall member defining a backing plane; wherein the linkage arm extends forwardly from the backing plane; wherein in a linkage arm dispensing position, the linkage arm forms a first angle with the backing plane; and wherein in a linkage arm roll changing position, the linkage arm forms a second angle with the backing plane, the second angle being greater than the first angle. 5. The web material dispenser of claim 4 , wherein the second attachment location of the linkage arm is a fixed location on the linkage arm; wherein the first attachment location of the linkage arm defines a pivot axis of the linkage arm, representing a first pivot axis, parallel to the backing plane, the linkage arm being rotatable about the first pivot axis relative to the housing; and wherein the second attachment location of the linkage arm defines a pivot axis of the roll support arm, representing a second pivot axis, the second pivot axis being parallel to the first pivot axis, the roll support arm being rotatable about the second pivot axis relative to the linkage arm. 6. The web material dispenser of claim 5 , wherein when the dispenser is in use, the pivot axis of the linkage arm is located above the pivot axis of the roll support arm. 7. The web material dispenser of claim 5 , wherein the pivot axis of the roll support arm is located between the first and second ends of the roll support arm. 8. The web material dispenser of claim 1 , wherein the roll support arm is operable to pivot about the second attachment location of the linkage arm between at least one support arm roll changing position and at least one support arm dispensing position; wherein in the at least one support arm dispensing position of the roll support arm, one of the mandrels is located above the other of the mandrels. 9. The web material dispenser of claim 8 , wherein: in the at least one support arm dispensing position, the roll support arm extends substantially vertically relative to the ground; and in the at least one support arm roll-changing position, the roll support arm extends substantially horizontally relative to the ground. 10. The web material dispenser of claim 8 , wherein the first and second mandrels are maintained at a fixed position relative to one another and relative to the housing when the roll support arm is in the at least one support arm dispensing position for dispensing material. 11. The web material dispenser of claim 8 , wherein the roll support assembly further comprises a retaining mechanism operable to selectively retain the roll support arm in the at least one support arm dispensing position thereof or in the at least one support arm roll changing position thereof. 12. The web material dispenser of claim 1 , wherein: the first and second mandrels extend from the first end and from the second end of the roll support arm, respectively; and the first and second mandrels comprising first and second extending ends, respectively, said first and second extending ends being open. 13. The web material dispenser of claim 4 , wherein: the housing comprises the back-wall member and a cover member having an opening, the cover member further being movable between a closed position and an open position; in the closed position of the cover member, the first and second mandrels are partially enclosed within the housing; and in the open position of the cover member, the linkage arm and the roll support arm can both be pivoted to replace the first or second rolls of web material when depleted and/or to switch positions of the first and second rolls of web material relative to the opening. 14. The web material dispenser of claim 13 , wherein: in the closed position and upon the first roll of web material being supported on the first mandrel and the second roll of web material being supported on the second mandrel, at least a portion of each of the first roll of web material and the second roll of web material is accessible through the opening of the cover member. 15. The web material dispenser of claim 4 , further comprising: an interfacing member extending forwardly from the back-wall member, the linkage arm being pivotally attached to the interfacing member; wherein the interfacing member is coupled to one of a left side and a right side of the housing. 16. The web material dispenser of claim 15 , wherein the interfacing member comprises an arcuate guiding mechanism operable to guide pivotal movement of the linkage arm relative to the housing, the arcuate guiding mechanism of the interfacing member providing an arc-shaped path; and wherein the linkage arm comprises a follower element operatively engaging the arcuate guiding mechanism along the arc-shaped path. 17. A web material dispenser comprising: a housing comprising a back-wall member and a cover member having an opening, the cover member further being movable between a closed position and an open position; a roll support assembly coupled to the housing and having a roll support arm, the roll support arm having a first end and a second end, opposite the first end, the roll support arm being pivotable within the housing between at least one support arm roll changing position and at least one support arm dispensing position; a first mandrel extending from the first end of the roll support arm, to support a roll of web material, an extending end of the first mandrel being open; and a second mandrel extending from the second end of the roll support arm, to support a second roll of web material, an extending end of the second mandrel being open; and wherein in the open position of the cover member, pivoting of the roll supp
