Abstract
A panel of a sectional door includes a panel frame and a sheet of material that is coupled to the panel frame. The panel frame includes a top frame member, a bottom frame member, a first side frame member and a second side frame member. The frame members include a rear surface and a front surface, and the front surface includes a ledge. The sheet of material is coupled to the front surface such that a bottom edge of the sheet rests on the ledge and a front surface of the sheet is unobstructed by the panel frame.
Claims19
An upward acting, multi-panel door, the door comprising:
- a first panel frame of a plurality of panel frames rotatably coupled together and movable, the first panel frame comprising a ledge and defining an opening, the ledge extending continuously along a majority of a longitudinal length of the first panel frame, wherein the ledge is cantilevered outward from a proximal end of the ledge and free of a vertical extension at a distal end of the ledge, the opening extending across a majority of an area defined by an outer perimeter of the first panel frame, wherein a bottom surface of the ledge extends perpendicularly outward from the first panel frame, wherein the bottom surface of the ledge is spaced apart from a bottom edge of the first panel frame in a direction opposite a direction in which the bottom surface faces, and wherein a top surface of the ledge is disposed on an opposing side of the ledge from the bottom surface, wherein the first panel frame comprises a bottom frame member, wherein the bottom frame member is formed as an aluminum extrusion;
- a sheet of material having a rear surface and an opposed front surface, the rear surface coupled to a front surface of the first panel frame such that a bottom edge of the sheet rests on the ledge, wherein no portion of the first panel frame contacts the front surface of the sheet such that the front surface of the sheet is unobstructed;
- a second panel frame of the plurality of panel frames, the second panel frame comprising a top frame member having a front surface, wherein the sheet of material coupled to the first panel frame is substantially entirely disposed outward of the top frame member of the second panel frame in a direction the front surface of the top frame member of the second panel frame faces;
- and
- a hinge rotatably coupling the first panel frame of the plurality of panel frames to the second panel frame.

An upward acting, multi-panel door, the door comprising:
- a first panel frame, including an inward facing surface, an outward facing surface, and a ledge cantilevered outward from the outward facing surface at a proximal end of the ledge and being free of a vertical extension at a distal end thereof, the ledge having a top surface and a bottom surface, the bottom surface being spaced apart from a bottom edge of the first panel frame defined by a bottom frame member comprising aluminum, the ledge extending continuously along a majority of a longitudinal length of the first panel frame;
- a panel having a front surface and a rear surface, wherein the rear surface of the panel is coupled to the outward facing surface of the first panel frame and covers an opening defined by the first panel frame, the opening extending across a majority of an area defined by an outer perimeter of the outward facing surface of the first panel frame, wherein a lower edge of the panel rests on the top surface of the ledge;
- a second panel frame including a top frame member defining a top edge, the top edge configured to contact the bottom edge of the bottom frame member of the first panel frame along a reference plane substantially parallel to the top surface of the ledge when the door is in a closed configuration, wherein a contact interface between the top edge of the top frame member of the second panel frame and the bottom edge of the bottom frame member of the first panel frame is formed of at least two discontiguous regions on the reference plane separated by a portion of the top frame member of the second panel frame extending above the reference plane, wherein at least a portion of the bottom edge of the first panel frame is disposed below and parallel to the bottom surface of the ledge;
- and
- a hinged connection configured to hingedly couple the first panel frame to the second panel frame,
- wherein the ledge is configured to be spaced apart from and not contact the second panel frame.
