Abstract
A garage door carrier system carries an overhead garage door between a closed position blocking entry of a vehicle into a garage, and an open position allowing entry of the vehicle into the garage. The garage door is in rolling engagement with a track that guides the garage door. A lever, rotating about a pivot, has a counterweight at a first end and is rotatably connected to the garage door at a second opposite load end. The counterweight provides in-force at the first end that translates as out-force at the load end as the lever rotates about the pivot to carry the garage door between the closed position and the open position.

A carrier system for carrying a garage door between a defined closed position in which the garage door is generally vertical and blocks entry of a vehicle into a garage through an opening, and a defined open position in which the garage door is generally horizontal and allows entry of the vehicle into the garage through the opening, the carrier system comprising:
- a track for guiding the garage door by rolling engagement with the track;
- a lever rotatable about a pivot, the lever having an in-lever arm at a first side of the pivot and an out-lever arm at a second, opposing, side of the pivot, the out-lever arm extending from the pivot to a load end, the load end rotatably connected to the garage door;
- and
- a counterweight connected to the in-lever arm to provide in-force at the in-lever arm, translated as out-force at the load end of the out-lever arm, as the lever rotates about the pivot, to carry the garage door between the defined closed position and the defined open position.
A method of carrying a garage door between a defined closed position in which the garage door is generally vertical and blocks entry of a vehicle into a garage, and a defined open position in which the garage door is generally horizontal and allows entry of the vehicle into the garage, comprising:
- rotating a lever about a pivot, the lever having an in-lever arm at a first side of the pivot, an out-lever arm at a second, opposing, side of the pivot and rotatably connected to the garage door at a load end, and a counterweight connected to the in-lever arm,
- wherein the counterweight provides in-force at the in-lever arm, translated as out-force at the load end of the out-lever arm, as the lever rotates about the pivot, to carry the garage door between the defined closed position to the defined open position.
