Abstract
In one aspect, the present disclosure is directed to a sheet material dispenser that includes a feed roller that is rotatable to facilitate dispensing of the sheet material from a discharge in a housing of the dispenser. The dispenser can have a cutting assembly that includes a cutting blade and at least one movable support coupled to cutting blade and that is actuated with rotation of the feed roller to cause movement of the cutting blade to at least partially cut, score, or perforate the sheet material during dispensing thereof. The dispenser also can have a biasing assembly coupled to the feed roller body to assist rotation of the feed roller body and/or movement of the cutting blade. Other aspects also are described.
Claims18
A sheet material dispenser, comprising:
- a dispenser housing with a supply of sheet material received therein;
- a feed roller adjacent the supply of sheet material, the feed roller including a feed roller body having a chamber defined therein, wherein upon rotation of the feed roller, the feed roller at least partially engages and feeds the sheet material from the supply of sheet material along a path of travel from the supply of sheet material through the dispenser housing;
- a cutting assembly at least partially disposed within the chamber defined in the feed roller body, the cutting assembly including a cutting blade and at least one movable support coupled to the cutting blade and the feed roller body, wherein the cutting blade is moved with rotation of the feed roller so as to move through one or more openings defined in the feed roller body to at least partially cut, score, or perforate the sheet material during dispensing of a selected portion thereof;
- and
- a biasing assembly including at least one biasing member coupled to the feed roller body to assist rotation of the feed roller and/or movement of the cutting blade through the one or more openings defined along the feed roller body during rotation of the feed roller.
A sheet material dispenser, comprising:
- a dispenser housing having a supply of sheet material supported therein and a discharge through which the sheet material is dispensed;
- a feed roller rotatably mounted within the dispenser housing, and including a feed roller body having a chamber defined therein, and an exterior surface that at least partially engages the sheet material;
- wherein the sheet material is fed from the supply of sheet material along a path of travel toward the discharge by rotation of the feed roller;
- a cutting assembly comprising:
- a cutting blade received within the chamber of the feed roller body and movable into and out of the feed roller body through at least one opening defined therein,
- a movable support coupled to the cutting blade and having a first end connected to the feed roller body and a second end, and
- a cam track defined within the chamber of the feed roller body,
- wherein the second end of the movable support is connected to a cam follower that engages the cam track such that as the feed roller rotates, the cam follower moves about the cam track, causing the movable support to be pivoted about the first end thereof and move the cutting blade through the at least one opening defined in the feed roller body and toward engagement with the sheet material;
- and
- a biasing assembly including one or more biasing members extending at partially along the feed roller body and coupled to the feed roller body to assist rotation thereof, to facilitate movement of the cutting blade, or a combination thereof.
A dispenser for dispensing a sheet material, comprising:
- a feed roller having a feed roller body with an interior chamber defined therein, the feed roller at least partially engaging the sheet material for feeding or the sheet material along a path of travel as the feed roller is rotated;
- a cutting assembly disposed within the chamber of the feed roller body, the cutting assembly including a cutting blade and a movable support, the movable support being connected to an interior surface of the feed roller body at a first end and to a cam follower at a second end;
- wherein as the feed roller is rotated, the cam follower moves about a cam track defined along the chamber of the feed roller body, such that the movable support is pivoted about the first end thereof to move the cutting blade toward engagement with the sheet material;
- and
- a biasing assembly including at least one biasing member extending along a rotational axis of the feed roller body and configured to assist rotation of the feed roller, to facilitate movement of the cutting blade, or a combination thereof.
