Abstract

Dispensing towels includes: the step of extending the toweling exterior of the housing for grasping by a user; and subsequent thereto, the step of retracting the toweling into the housing. The housing includes a main body, and a loading door that is configured to rotate relative to the main body between a closed position, in which the housing is configured to extend toweling there from, and an open position, in which the housing is configured to receive toweling therein. The loading door serves as a towel carrier and has a curved surface defining a cavity within which a roll of paper towels is received and retained in floating engagement therewith. The roll of paper towels rolls and slides on the curved surface when unwinding during said step of extending the toweling exterior of the housing for grasping by a user.

(b) wherein at least one end of the first roller moves such that an axis of rotation of the first roller moves relative to the main body of the housing; and

(c) wherein the method further comprises the step of moving the loading door into the closed position after loading toweling within the dispenser, with the first roller being urged into engagement with the second roller when the loading door enters the closed position and the second roller acting on the first roller so as to displace at least one end of the first roller when the loading door enters the closed position.

5. The method of claim 4, wherein the guide system comprises a first roller attached to the main body and a second roller attached to the loading door.

6. The method of claim 5, wherein the second roller is the only roller of the guide system affixed to the loading door.

7. The method of claim 5, wherein the second roller comprises a lower drive roller of the guide system, and the first roller comprises an upper drive roller of the guide system, the lower drive roller engaging the upper drive roller with toweling extending there between when the loading door is moved into the closed position with toweling draped over the loading door.

8. The method of claim 5, wherein the loading door has a second curved surface that defines a second cavity within which the second roller is retained.

9. The method of claim 4, wherein the dispenser further comprises a motor assembly configured to cause a leading edge of the toweling to be extended from a housing of the dispenser and to cause the toweling to be subsequently retracted back into the housing, both of the steps of extending the toweling exterior of the housing for grasping by a user and the step of retracting the toweling into the housing being accomplished using the motor assembly;

and the method further comprising the steps of sensing a leading edge of the toweling while retracting the toweling into the housing, and ceasing retracting of the toweling into the housing as a function of sensing the leading edge of the toweling.

10. The method of claim 4, wherein the housing comprises extension walls located proximate opposite exterior sides of the housing that extend above a top side of the housing, and wherein the method further comprises a preliminary step of mounting the dispenser to the underside of a fixture, including removing a portion of each extension wall along a score line so as to adjust the distance from the underside of the fixture below which the top side of the housing is mounted.

11. The method of claim 10, wherein the dispenser further comprises a motor assembly configured to cause a leading edge of the toweling to be extended from a housing of the dispenser and to cause the toweling to be subsequently retracted back into the housing, both of the steps of extending the toweling exterior of the housing for grasping by a user and the step of retracting the toweling into the housing being accomplished using the motor assembly;

and the method further comprising the steps of sensing a leading edge of the toweling while retracting the toweling into the housing, and ceasing retracting of the toweling into the housing as a function of sensing the leading edge of the toweling.

12. The method of claim 1,

(a) wherein the toweling comprises a roll of paper towels and the dispenser is configured to unwind roll of paper towels during extension of toweling from the housing but not rewind the roll of paper towels during subsequent retraction of toweling into the housing, and

(b) wherein a back side of the housing includes an opening that is configured such that excess toweling gathering within the housing may fall as a result of retraction of toweling back into the housing.

13. The method of claim 12, wherein the dispenser further comprises a motor assembly configured to cause a leading edge of the toweling to be extended from a housing of the dispenser and to cause the toweling to be subsequently retracted back into the housing, both of the steps of extending the toweling exterior of the housing for grasping by a user and the step of retracting the toweling into the housing being accomplished using the motor assembly;

and the method further comprising the steps of sensing a leading edge of the toweling while retracting the toweling into the housing, and ceasing retracting of the toweling into the housing as a function of sensing the leading edge of the toweling.
