Abstract

A towel dispenser includes a housing for receiving toweling. The housing includes a main body; a loading door that is configured to rotate relative to the main body between a closed position and an open position; and a guide system that includes a first roller attached to the main body and a second roller attached to the loading door. The towel dispenser may include a motor for driving dispensing of the toweling from the housing and an associated sensor. The towel dispenser can be mounted to an underside of a cabinet. In an aspect, the front wall of the main body and a lip of the loading door collectively define a gap to which the guiding system guides the toweling and through which towels are dispensed when the loading door is in the closed position.

3. The towel dispenser of claim 2, wherein the second roller comprises an axis of rotation that is fixed relative to the loading door regardless of whether the loading door is in the closed position or the open position, or transitioning therebetween;

wherein the axis of rotation of the first roller is substantially parallel to the axis of rotation of the second roller regardless of whether the loading door is in the closed position or the open position, or transitioning therebetween; and

wherein the second roller attached to the loading door and the first roller attached to the housing are configured to trap toweling therebetween when the loading door is rotated from the open position to the closed position with a length of the toweling extending over the loading door.

4. The towel dispenser of claim 2, wherein a portion of the main body extends over the lip of the loading door when the loading door is in the closed position, but not when the loading door is in the open position;

and wherein a motor for feeding the toweling outside of the housing during dispensing of a towel is located within the portion of the main body extending over the lip of the loading door.

5. The towel dispenser of claim 2, wherein the loading door forms a majority of the underside of the dispenser when the loading door is in the closed position.

6. An automatic paper towel dispenser, comprising:

(a) toweling comprising a roll of perforated paper towels; and

(b) a housing in which the roll of perforated paper towels is received for dispensing, the housing comprising,

(i) a main body,

(ii) a loading door that is configured to rotate relative to the main body between,

(A) a closed position, in which the housing is configured to dispense towels therefrom, and

(B) an open position, in which the housing is configured to receive toweling therein, and

(iii) a guide system configured to guide the toweling while towels are dispensed from the housing, the guide system comprising a first roller attached to the main body and a second roller attached to the loading door, and

(iv) a motor located within the housing for feeding the toweling outside of the housing during dispensing of a towel;

(c) wherein the loading door comprises a loading door body defining an area within which the toweling is positioned when the toweling is received in the housing and a lip that extends away from the loading door body; and

(d) wherein the front wall of the main body and the lip of the loading door collectively define a gap to which the guiding system guides the toweling and through which towels are dispensed when the loading door is in the closed position.

7. The automatic paper towel dispenser of claim 6, further comprising a transmission attached to the main body of the housing, wherein the second roller attached to the loading door is connectable to the transmission and is driven by the motor via the transmission when the loading door is in the closed position.

8. The automatic paper towel dispenser of claim 7, wherein the second roller comprises an axis of rotation that is fixed relative to the loading door regardless of whether the loading door is in the closed position or the open position, or transitioning therebetween;

wherein the axis of rotation of the first roller is substantially parallel to the axis of rotation of the second roller regardless of whether the loading door is in the closed position or the open position, or transitioning therebetween; and

wherein the second roller attached to the loading door and the first roller attached to the housing are configured to trap toweling therebetween when the loading door is rotated from the open position to the closed position with a length of the toweling extending over the loading door.

9. The automatic paper towel dispenser of claim 7, wherein a portion of the main body extends over the lip of the loading door when the loading door is in the closed position, but not when the loading door is in the open position;

and wherein the motor for feeding the toweling outside of the housing during dispensing of a towel is located within the portion of the main body extending over the lip of the loading door.

10. The automatic paper towel dispenser of claim 7, wherein the loading door forms a majority of the underside of the dispenser when the loading door is in the closed position.

11. A towel-dispensing apparatus, comprising:

(a) a cabinet; and

(b) a paper towel dispenser mounted to an underside of the cabinet, the paper towel dispenser comprising a housing in which toweling comprising a roll of perforated paper towels is contained for dispensing, the housing comprising,

(i) a main body,

(ii) a loading door that is configured to rotate relative to the main body between,

(A) a closed position, in which the housing is configured to dispense towels therefrom, and

(B) an open position, in which the housing is configured to receive toweling therein, and
