Towel dispenser
An improved towel dispenser includes a rotatable driveshaft mounted in a one-way clutch bearing fitted with a pinion which engages a vertically oriented press bar assembly including at its lower portion a rack which engages the pinion to advance paper towel through a dispensing nip upon pivotable motion of the press bar assembly. A dispensing chute located below the dispensing nip includes a lower shelf configured to direct web forwardly toward the front portion of a dispenser. The gear rack is preferably an internal gear rack integrally formed with a unitary press bar assembly member. The dispensing chute is configured such that an angle between a cutting-blade and the outer lip of the shelf makes an angle with a vertical of at least about 25°.
1. A dispenser for dispensing sheet material from a roll, comprising:
a feed roller rotatably mounted to a housing to thereby dispense sheet material from the roll;
a press bar assembly having a first orientation that is generally vertical, the press bar assembly being pivotably mounted to the housing so as to be pivotable about a pivot axis extending through the press bar assembly, the press bar assembly comprising a rack operatively connected to the feed roller to cause the feed roller to be rotated when the press bar assembly pivots about the pivot axis; and
a handle extending from the housing and oriented in the first orientation, the handle being in engagement with the press bar assembly and configured to be pushed by a user generally into the housing of the dispenser, such that the press bar assembly pivots about the pivot axis,
wherein the handle comprises an upper end portion in vertical proximity to the pivot axis and an opposed lower end portion in vertical proximity to the rack,
wherein the press bar assembly has a top and a bottom separated by a distance and the rack is disposed more than about 65% of that distance from the top of the press bar assembly toward the bottom of the press bar assembly, and
wherein the top of the press bar assembly is aligned with an upper end of the upper end portion of the handle.
2. The dispenser of claim 1 , wherein the first orientation is perpendicular to an axis of the feed roller.
3. The dispenser of claim 1 , further comprising a pinion in engagement with the rack, the pinion being coupled to a driveshaft in engagement with the feed roller, such that rotation of the pinion causes rotation of the feed roller.
4. The dispenser of claim 3 , wherein the driveshaft is mounted in a one-way clutch bearing, such that the driveshaft advances only when the press bar assembly is pushed inwardly.
5. The dispenser of claim 1 , further comprising a spring engaging the push arm assembly to normally bias the push arm assembly to a rest position.
6. The dispenser of claim 1 , further comprising a pivot pin that supports the press bar assembly.
7. The dispenser of claim 1 , wherein the handle comprises a concave contact surface.
8. The dispenser of claim 1 , wherein the handle comprises a contact surface having a width that is less than a width of a front portion of the housing, such that the handle is configured to be pushed into the front portion of the housing.
