Low reserve indicator for a paper towel dispenser
View Patent ↗A paper towel dispenser includes a housing with an inner chamber configured to support a paper supply and a dispensing aperture for dispensing paper from the paper supply. The paper supply includes a side that is formed by superimposed edge portions of paper from the paper supply. An indicator mechanism is affixed to the housing within the inner chamber and is disposed adjacent the paper supply. The indicator mechanism includes an indicator operably connected to a release mechanism. The indicator is movable between a retracted position and an indicating position. The release mechanism is pivotally biased away from the housing and is releasable in response to the paper supply being reduced below a predetermined amount. Upon release of the release mechanism, the release mechanism causes the indicator to move to the indicating position.
1. A paper dispenser comprising:
a housing having an inner chamber configured to support a paper supply and a dispensing aperture for dispensing paper from the paper supply, the paper supply having a side portion formed by superimposed edge portions of the paper supply; and
an indicator mechanism affixed to the housing within the inner chamber adjacent the paper supply, the indicator mechanism comprising:
an indicator movable between a retracted position and an indicating position, and
a release mechanism operably connected to the indicator and pivotally biased relative to the housing, the release mechanism positionally movable relative to the indicator so as to engage an outer periphery of the paper supply and enable the outer periphery of the paper supply to vary in position relative to the housing with the indicator in the retracted position, the release mechanism engaging the side portion formed by superimposed edge portions of the paper supply to maintain the release mechanism in the retracted position, the release mechanism being releasable in response to a quantity of the paper supply at an inner periphery of the paper supply being reduced to a predetermined non-zero reserve quantity, wherein the side portion formed by superimposed edge portions of the paper supply no longer engages the release mechanism, and wherein upon being released the release mechanism causes the indicator to move to the indicating position.
2. The paper dispenser of claim 1 , wherein the indicator is pivotable about a first axis.
3. A paper dispenser comprising:
a housing having an inner chamber configured to support a paper supply and a dispensing aperture for dispensing paper from the paper supply, the paper supply having a side portion formed by superimposed edge portions of the paper supply; and
an indicator mechanism affixed to the housing within the inner chamber adjacent the paper supply, the indicator mechanism comprising:
an indicator movable between a retracted position and an indicating position, and
a release mechanism operably connected to the indicator and pivotally biased relative to the housing, the release mechanism positionally movable relative to the indicator so as to engage an outer periphery of the paper supply and enable the outer periphery of the paper supply to vary in position relative to the housing with the indicator in the retracted position, the release mechanism being releasable in response to a quantity of the paper supply at an inner periphery of the paper supply being reduced to a predetermined non-zero reserve quantity, wherein the side portion formed by superimposed edge portions of the paper supply no longer engages the release mechanism, and wherein upon being released the release mechanism causes the indicator to move to the indicating position;
wherein the indicator is pivotable about a first axis, and
wherein the release mechanism is pivotable about a second axis and is connected to the indicator by a pin-and-slot connection.
4. The paper dispenser of claim 1 , the indicator mechanism further comprising a base member which is affixed to the housing, wherein the indicator and the release mechanism are coupled to the base member.
5. The paper dispenser of claim 1 , wherein the housing includes a pivotable door and the release mechanism is adapted to pivot counter to the direction of bias upon the door being pivoted to a closed position and engagement of the release mechanism with the paper supply.
6. A paper dispenser comprising:
a housing having an inner chamber configured to support a rolled paper supply having a side portions and a dispensing aperture for dispensing paper from the paper supply; and
an indicator mechanism affixed to the housing within the inner chamber adjacent the rolled paper supply, the indicator mechanism comprising:
an indicator movable between a retracted position and an indicating position, and
a release mechanism operably connected to the indicator and pivotally biased relative to the housing, the release mechanism positionally movable relative to the indicator so as to engage an outer periphery of the paper supply and enable the outer periphery of the paper supply to vary in position relative to the housing with the indicator in the retracted position, the release mechanism engaging the side portion formed by superimposed edge portions of the paper supply to maintain the release mechanism in the retracted position, the release mechanism being releasable in response to a quantity of the paper supply at an inner periphery of the rolled paper supply being reduced to a predetermined reserve amount corresponding to a low remaining quantity of the paper supply wherein side portion formed by superimposed edge portions of the paper supply no longer engages the release mechanism, and wherein upon being released the release mechanism causes the indicator to move to the indicating position.
7. A paper dispenser comprising:
a housing having an inner chamber adapted to support a paper supply having a side portion formed by superimposed edge portions of the paper supply and a dispensing aperture for dispensing paper from the paper supply, the housing including a first section hingedly affixed to a second section; and
an indicator mechanism affixed to the first section, wherein hinged movement of the first section toward the second section and contact between the indicator mechanism and the side portion formed by superimposed edge portions of the paper supply shifts the indicator mechanism to a retracted position, and wherein the indicator mechanism shifts to an indicating position upon an inner periphery of the paper supply being reduced below a predetermined reserve amount corresponding to a low remaining quantity of the paper supply wherein the side portion formed by superimposed edge portions of the paper supply no longer contacts the indicator mechanism.
