Abstract

Door and hinge construction for overhead doors is disclosed for use with sliding door panels, which includes combination hinge and roller housings engaged with and located at each side of the door panels, serving to retain the panels together, and which carry rollers which ride in tracks outside the door panel, with hinge and seal members engaged with the panels between the combination housings providing for hinged door movement and sealing against the entry of dirt and water.

Claims

1. A door hinge construction for a sliding overhead door, said door being intended to be carried in tracks at the sides thereof which comprises:

a plurality of stacked door panels in transverse meeting relationship and carried between said tracks;

said door panels having top and bottom edges, and side edges;

said door panel top edges having an upwardly extending rail including a first transverse groove therein;

said door panel bottom edges having a downwardly extending rail including a second transverse groove therein;

said upwardly extending and said downwardly extending rails of adjacent door panels being of complementary configuration;

seal means between adjacent panels engaged in said first and second transverse grooves, said seal means including first and second ribs carried in said first and second transverse grooves and a centerplate connecting said ribs, to provide thereby a hinge, and also retaining said panels in close relationship;

readily removable combination hinge and roller housing means between and in engagement with adjacent door panels, said hinge and roller housing means including first and second ribs carried in said first and second transverse grooves, said hinge and roller housing means being separated and independent from said seal means by being independently disengageable from said adjacent door panels by removing the first and second ribs of the hinge and roller housing means from the first and second transverse grooves;

said roller housing means including roller means for insertion in tracks at the sides of said door, said roller means being at said side edges of said door panels, wherein said readily removable combination hinge and roller housing means comprises;

a plate connecting said ribs of said roller housing means;

an offset sleeve extending rearwardly and outwardly from said door panels, said sleeve having a bore therein, said bore extending outwardly from said door panels;

a pin in said bore; and

said roller means carried by and being rotatable about said pin, whereby said roller means are disposed rearwardly and outwardly from said door panels.

2. A door and hinge construction as defined in claim 1 in which

said seal means are of molded plastic.

3. A door and hinge construction for a sliding overhead door, said door being intended to be carried in tracks at the sides thereof which comprises:

a plurality of stacked door panels in having top, bottom and side edges;

said door panel top edges having an upwardly extending rail including a first transverse groove therein;

said door panel bottom edges having a downwardly extending rail including a second transverse groove therein;

seal means between adjacent panels engaged in said first and second transverse grooves, said seal means including first and second ribs carried in said first and second transverse grooves and a center plate connecting said ribs, to provide thereby a hinge, and also retaining said panels in close relationship;

readily removable combination hinge and roller housing means between and in engagement with adjacent door panels, said hinge and roller housing means including first and second ribs carried in said first and second transverse grooves, said hinge and roller housing means being separate and independent from said seal means by being independently disengageable from said adjacent door panels by removing the first and second ribs of the hinge and roller housing means from the first and second transverse grooves;

said roller housing means having an offset portion extending rearwardly and outwardly from said door panels;

and roller means rotatably supported in said roller housing means for insertion in tracks at the sides of said door.

4. A door and hinge construction as defined in claim 3 in which

said top edge rail configuration includes a notch;

and

said bottom edge rail configuration includes a notch complementary to said top edge rail notch whereby engagement therebetween provides a tight joint.

5. The door and hinge construction for a sliding door as defined in claim 3 in which said uppermost door panel is provided with a seal means in said uppermost transverse edge groove, said uppermost door panel having adjusting brackets fastened thereto;

and said brackets each having roller means engaged in said tracks.
