Abstract

In example implementations, a vertical stacking door includes an end cap that is coupled to a panel. The end cap includes a body portion, a cam lever to rotate around an axis to generate a lift force to lift and separate an adjacent panel of a plurality of panels of the vertical stacking door, a first track wheel, a second track wheel, and a third track wheel.

First claim

The invention claimed is:

1 . A cam lever coupled to a top end of a body portion of an end cap for a first panel of a vertically stacking door, comprising:
a cam body portion comprising a first side and a second side, wherein the first side is opposite the second side, wherein a center of the cam body portion is pivotally mounted on an inner side of one of a right side and a left side of the end cap such that a portion of the cam body portion is positioned inside of the end cap between the right side and the left side of the end cap; a first cam wheel coupled to the first side of the cam body portion on a first end of the cam body portion, wherein the first cam wheel extends beyond a back side of the end cap; and a second cam wheel coupled to the second side of the cam body portion on a second end of the cam body portion, wherein the second cam wheel extends beyond an outer side of the one of the right side and the left side, where the outer side is opposite the inner side; wherein the first cam wheel and the second cam wheel are arranged such that movement of the second cam wheel in a downward direction causes the first cam wheel to move in an upward direction with a lift force to separate a second panel of the vertically stacking door from the first panel that is adjacent to the second panel.

2 . The cam lever of claim 1 , wherein the center of the cam body portion is coupled to the end cap via a rotatable coupling.

3 . The cam lever of claim 1 , wherein the second cam wheel interacts with a ramp on a vertical door guide that guides movement of the vertically stacking door to cause the first cam wheel to interact with the second panel.

4 . The cam lever of claim 3 , wherein an interaction of the second cam wheel with the ramp causes the cam body portion to rotate and move the second cam wheel in the downward direction and move the first cam wheel in the upward direction.

5 . The cam lever of claim 1 , wherein the first cam wheel and the second cam wheel are fabricated from at least one of: a nylon or a plastic.

6 . The cam lever of claim 1 , wherein an amount the cam body portion can rotate relative to the end cap is limited by the end cap.

7 . A cam lever coupled to a top end of a body portion of an end cap for a first panel of a vertically stacking door, comprising:
a cam body portion comprising a first side and a second side, wherein the first side is opposite the second side, wherein the cam body portion comprises an opening adjacent a center of the cam body portion which receives a rotatable mechanical coupling that rotatably mounts the cam body portion on an inner side of one of a right side and a left side of the end cap such that a portion of the cam body portion is positioned inside of the end cap between the right side and the left side of the end cap, the rotatable mechanical coupling configured to allow the cam body portion to rotate around an axis of the rotatable mechanical coupling; a first cam wheel coupled to the first side of the cam body portion on a first end of the cam body portion, wherein the first cam wheel extends beyond a back side of the end cap; and a second cam wheel coupled to the second side of the cam body portion on a second end of the cam body portion, wherein the second cam wheel extends beyond an outer side of the one of the right side and the left side, wherein the outer side is opposite the inner side, wherein the first cam wheel and the second cam wheel are arranged such that movement of the second cam wheel in a downward direction causes the first cam wheel to move in an upward direction with a lift force to separate a second panel of the vertically stacking door from the first panel that is adjacent to the second panel.

8 . The cam lever of claim 7 , wherein the second cam wheel interacts with a ramp on a vertical door guide that guides movement of the vertically stacking door to cause the first cam wheel to interact with the second panel.

9 . The cam lever of claim 8 , wherein an interaction of the second cam wheel with the ramp causes the cam body portion to rotate and move the second cam wheel in the downward direction and move the first cam wheel in the upward direction.

10 . The cam lever of claim 7 , wherein the first cam wheel and the second cam wheel are fabricated from at least one of: a nylon or a plastic.

11 . The cam lever of claim 7 , wherein an amount the cam body portion can rotate relative to the end cap is limited by the end cap.
