Abstract
A manual release structure and roll-up door assembly is provided such that the edges of the roll-up door can be intentionally disengaged from the guideway. This is accomplished by using modified roll-up door elements at the edges of the door. One modification is made to the rail within which the door edges reside when the door is in its down or “closed” position. Another modification is made to a face frame slide within which the rail resides. Still another modification is made to the edges of the roll-up door. Together, these modifications result in an improved manual release structure to be used when release of the door edge becomes necessary.
Claims18
A manual release structure for use with a roll-up door comprising:
- a longitudinally and vertically extending wall clip disposed to one side of a doorway;
- a longitudinally and vertically extending face frame slide captured within the wall clip, the face frame slide comprising a U-shaped structure having an opening facing inwardly of the doorway and protrusions at each side of the opening;
- a rearward facing notch disposed in the face frame slide at a point, the notch extending a length at each side of the face frame slide;
- and
- a longitudinally and vertically extending rail captured within the face frame slide opening and retained in place by the protrusions of the opening, the rail comprising a vertical axis, an opening and at least one vertical slit parallel to the axis;
- wherein the at least one vertical slit is disposed in the rail at the point of the face frame slide slot;
- and
- wherein the at least one slit allows the rail to flex and the opening to expand at the point of the face frame slide notch.
A manual release structure for use with a roll-up door, the roll-up door comprising a central door panel disposed within a doorway and flanked by two lateral vertical edges, the edges having an irregular shape, and the manual release structure comprising:
- a longitudinally and vertically extending wall clip disposed to each side of the doorway;
- a longitudinally and vertically extending face frame slide captured within the wall clip, the face frame slide comprising a U-shaped structure having an opening facing inwardly of the doorway and protrusions disposed at each side of the opening;
- a rearward facing notch disposed in the face frame slide at a point, the notch extending a length at each side of the face frame slide;
- and
- a longitudinally and vertically extending flexible rail captured within the face frame slide opening and retained in place by the protrusions of the opening, the rail comprising a vertical axis, an opening and at least one vertical slit parallel to the axis;
- wherein a lateral edge of the roll-up door can be retained within and pass through the rail;
- wherein the at least one vertical slit is disposed in the rail at the point of the face frame slide slot;
- and
- wherein the at least one slit allows the rail to flex and the opening to expand at the point of the face frame slide notch.
