Abstract
A garage door motion assembly moves a garage door horizontally towards the wall surrounding the garage door opening as the garage door travels through its last few inches of closing travel. The garage door is moved horizontally into the garage door seal, creating a better seal between the door and the door seal. The horizontal movement of the garage door towards the seal may be precisely adjusted to create the desired closure motion and sealing performance of the garage door. Damage to the garage door and door seal while closing is avoided.

A garage door motion system for closing a garage door comprising:
- a garage door track that facilitates movement of the garage door between an open position and a closed position;
- a garage door comprising garage door panels, hinges between the garage door panels, and roller wheels carried by the garage door track that move the garage door along the garage door track;
- a high throw cam assembly comprising:
- a bracket which is attached adjacent a side edge of an upper garage door panel, the bracket comprising a first pivot location and a second pivot location;
- a door closing arm which is pivotably attached to the bracket at the first bracket pivot location, the door closing arm comprising a distal end with an axle that holds a garage door roller wheel that engages the garage door track, and a proximal end comprising a second door closing arm pivot location;
- an intermediate lever having a first pivot location pivotably attached to the bracket at the second bracket pivot location, the intermediate lever further comprising a second pivot location and a third pivot location;
- an input linkage having a first end pivotably attached to the intermediate lever third pivot location and a second end comprising a laterally extending axle and a roller carried on the axle, the roller contacting and moving along an edge of the garage door track;
- an intermediate linkage having a first end pivotably attached to the intermediate lever second pivot location and a second end pivotably attached to the door closing arm second pivot location;
- and
- a stationary stop bracket;
- wherein, as the garage door is moved towards a closed position, the roller contacts the stop bracket and the stop bracket stops downward movement of the roller and causes the input linkage to pivot the intermediate lever upwards, thereby moving the intermediate linkage upwards and pivoting the door closing arm away from the top garage door panel to separate the door closing arm roller wheel from the top garage door panel and to move the top garage door panel away from the garage door track.

- an intermediate lever pivotably attached to the bracket at the second bracket pivot location;
- an input linkage having a first end pivotably attached to the intermediate lever and a second end comprising an input arm, wherein the input arm is positioned adjacent an inside edge of the garage door track;
- an intermediate linkage having a first end pivotably attached to the intermediate lever and a second end pivotably attached to the door closing arm;
- and
- a stationary stop bracket;
- wherein, as the garage door is moved towards a closed position, the input arm contacts the stop bracket and the stop bracket stops further downward movement of the input arm and causes the input linkage to pivot the intermediate lever upwards, thereby moving the intermediate linkage upwards and pivoting the door closing arm away from the garage door panel to separate the door closing arm roller wheel from the garage door panel and to move the garage door panel away from the garage door track.

- an input linkage which is connected to the door closing arm and which is independently pivotable relative to the door closing arm, the input linkage comprising an input arm which is positioned adjacent an inside edge of the garage door track such that the input arm moves along the inside edge of the garage door track as the garage door closes;
- a stationary stop bracket;
- wherein, as the garage door is moved towards a closed position, the input arm contacts the stop bracket and the stop bracket stops further downward movement of the input arm and causes the door closing arm to pivot away from the garage door panel to separate the door closing arm roller wheel from the garage door panel and to move the garage door panel away from the garage door track and towards the wall.
