Vertical stability roller for vertically stacking panels
In example implementations, an end cap for a panel of a vertically stacking panel door is provided. The end cap includes a body to be coupled to an end of a panel of a vertically stacking panel door, a first track wheel coupled to the body, a second track wheel coupled to the body, and a vertical stability roller coupled to the body, wherein the first track wheel, the second track wheel, and the vertical stability roller are arranged along a vertical line, wherein the first track wheel is located vertically above the second track wheel and the vertical stability roller is located between the first track wheel and the second track wheel.
1. A vertically stacking panel door system, comprising
a vertically stacking panel door comprising a plurality of disconnected panels, wherein a top most panel of the plurality of disconnected panels comprises:
a first end cap coupled to a first end of the top most panel; and
a second end cap coupled to a second end of the top most panel, wherein the first end is opposite the second end, wherein each of the first end cap and the second end cap comprises:
a first track wheel coupled to a body;
a second track wheel coupled to the body; and
a vertical stability roller coupled to the body;
a vertical track guide;
a panel interface zone comprising an upper track portion and a lower track portion, wherein the lower track portion comprises an additional outer track portion, wherein the vertical stability roller is to interact with the additional outer track portion; and
a horizontal track guide comprising an upper horizontal track that is coupled to the upper track portion of the panel interface zone and a lower horizontal track that is coupled to the lower track portion of the panel interface zone.
2. The vertically stacking panel door system of claim 1 , wherein a distance between the vertical stability roller and the first track wheel is equal to a distance between the upper track portion and the additional outer track portion of the panel interface zone.
3. The vertically stacking panel door system of claim 1 , wherein the first track wheel moves within the upper track portion of the panel interface zone, the vertical stability roller moves along the additional outer track portion of the panel interface zone, and the second track wheel moves within the lower track portion of the panel interface zone as the vertically stacking panel door is opening.
4. The vertically stacking panel door system of claim 1 , wherein the vertical stability roller of the first end cap and the second end cap is coupled to a separate body that is mechanically coupled to the body of the first end cap and the second end cap.
5. The vertically stacking panel door system of claim 1 , wherein the first track wheel, the vertical stability roller, and the second track wheel are aligned on a common vertical line and the vertical stability roller is located between the first track wheel and the second track wheel.
