Sheet Product Dispenser

A dispenser for dispensing sheet product from a roll to a user, the dispenser comprising:

• a feed roll for dispensing a length of the sheet product from the roll to the user;
• a spring in operable communication with the feed roll to rotate the feed roll;
• and
• a push arm pivotally mounted about an axis disposed proximate one end of the push arm, the push arm in operable communication with the spring and biased in a first direction to a rest position by the spring, the push arm responsive to energy from the user to move in a second direction opposite the first direction and to transfer the energy to the spring;
• wherein the spring is in operable connection with the feed roll to apply the transferred energy to generate motion of the push arm in the first direction toward the rest position and rotate the feed roll, thereby dispensing the sheet product.

A method of dispensing sheet product from a supply to a user, the method comprising:

• applying mechanical energy to an energy storage device via a user interface, the user interface being biased in a first direction toward a rest position by the energy storage device, the applied mechanical energy moving the user interface in a second direction opposite the first direction for storing energy in the energy storage device;
• ceasing further application of mechanical energy to the user interface, thereby permitting the user interface to be biased in the first direction under the influence of the stored energy in the energy storage device;
• and
• in response to the user interface moving in the first direction toward the rest position, transferring the stored energy from the energy storage device to a sheet product feed device via the user interface, resulting in dispensing of the sheet product from the supply to the user.
