Abstract
The present application is directed to a manual or automatic flush threshold door seal system used on folding exterior doors along with an alternate embodiment for conventional exterior entryway doors that will not impede the passage of a wheelchair. A flexible weather seal can be put in a retracted or down position within an aluminum extrusion imbedded within the threshold providing a flush access surface and may be raised up into the upright position providing an adequate weather seal.
Claims20
A zero step sill flush threshold door seal system comprising:
- (a) an extruded sill configured for folding doors incorporating one or more roller guide tracks having rollers that translate when the folding doors are opened and closed;
- (b) an offset folding door hinge used where the folding doors are offset;
- (c) a transverse door-locking cavity adjacent to said roller guide tracks, providing a locking means when the folding doors are in the closed position;
- and
- (d) a single integral flexible weather seal capable of being manually positioned in an up position when the folding doors are closed for weather sealing, or in a retracted down position, flush with said extruded sill, when the folding doors are open.
A zero step sill flush threshold door seal system comprising:
- (a) an extruded sill configured for folding doors incorporating one or more roller guide tracks having rollers that translate when the folding doors are opened and closed;
- (b) an offset folding door hinge used where the folding doors are offset;
- (c) a transverse door-locking cavity adjacent to said roller guide tracks, providing a locking means when the folding doors are in the closed position;
- and
- (d) a multiple sectioned flexible weather seal capable of being automatically positioned in an up position when the folding doors are closed for weather sealing, or in a retracted down position, flush with said extruded sill, when the folding doors are open;
- and
- (e) a seal lifting guide having a seal lifting guide sloped section located on said offset folding door hinge that moves transversely within said door locking cavity and automatically raises said flexible weather seal into the upright position for weather sealing when the folding doors are closed.
A method for making a zero step sill flush threshold door seal system comprising the steps of:
- (a) providing an extruded sill configured for folding doors incorporating one or more roller guide tracks having rollers that translate when the folding doors are opened and closed;
- (b) providing an offset folding door hinge used where the folding doors are offset;
- (c) providing a transverse door-locking cavity adjacent to said roller guide tracks, providing a locking means when the folding doors are in the closed position;
- and
- (d) providing a single integral flexible weather seal capable of being manually positioned in an up position when the folding doors are closed for weather sealing, or in a retracted down position, flush with said extruded sill, when the folding doors are open.
