Abstract

A dispenser for dispensing and advancing sheet material is provided. The dispenser includes a frame and a drive roller rotationally mounted to the frame. The drive roller is configured for engagement with sheet material so that rotation of the drive roller causes movement of the sheet material. A segmented gear with first and second drive segments is mounted to the frame and is in communication with the drive roller. A spring is included and is in communication with the segmented gear. The spring is configured so that rotation of the segmented gear causes the spring to store potential energy. Release of potential energy in the spring causes the segmented gear to rotate. A cutting blade is provided and is configured for cutting the sheet material in order to release potential energy. The dispenser allows for a piece of sheet material to be dispensed therefrom and subsequently presents the user with a new piece of sheet material for future removal.

Description

Background technique [0001] Dispensers are used to store and dispense sheet-like materials such as paper towels, sanitary napkins, toilet paper, paper products and similar items. Dispensers are typically placed in restaurants, kitchens, restrooms or wherever these sheet materials are needed. Dispensers are generally configured to function in the most hygienic manner possible when used in areas requiring cleanliness. [0002] Certain types of dispensers are configured to accommodate a roll of sheet material such that the free end of the sheet material is presented to the user. The sheet material sometimes engages the drive roller inside the housing such that pulling on the free end by the user causes the drive roller to rotate due to the frictional engagement with the sheet material. The drive roller may include a drive mechanism that allows the drive roller to rotate a predetermined degree amount to dispense a predetermined length of sheet material to the user. The cutting ...
