US Patent:

58575103, Jan 12, 1999

Filed:

Jan 29, 1997

Appl. No.:

8/789785

Inventors:

LeRoy G. Krupke - Carrollton TX
Foad Vafaie - Plano TX
James L. Grisham - Denison TX
David Scott Boucher - Rowlett TX

Assignee:

Overhead Door Corporation - Dallas TX

International Classification:

E05D 1506

US Classification:

160201

Abstract:

A sectional garage door is formed of rectangular door sections which include hollow extruded plastic rail members interconnected by hollow extruded plastic end and intermediate stile members to form a door section. The rail members and stile members may be fitted with internal tubular or channel shaped metal reinforcing members to minimize deflection of the door sections during use. The door sections may each include an externally fitted strut which is secured to a longitudinal side edge of a section and is connected directly to a reinforcing member disposed within one of the rail members without being forcibly connected to the rail member itself to allow for differential thermal expansion between the rail member and the reinforcing members. Rectangular panel inserts may be removably supported on each door section by removable retainer members and may include insulated panel inserts which may be added to the door sections before or after installation.

Assignee:

Overhead Door Corporation - Dallas TX

International Classification:

E06B 312

US Classification:

160235

Abstract:

An upward acting sectional door is formed of rectangular door sections which are interconnected to each other by a continuous hinge comprising opposed partial arcuate hinge members formed on a lower rail of an upper section and an upper rail of an adjacent lower section and engaged with a third hinge member comprising an elongated tubular pin having a D-shaped cross section. The hinge pin is secured against rotation by retainer members at opposite ends of one of the door sections. The hinge permits lateral assembly and disassembly of one door section relative to the other. Additional load bearing hinge members are provided connected to the lateral side edges of adjacent door sections and are interconnected by support members disposed in the tubular hinge pin for transferring part or all of the forces between adjacent door sections thereby allowing the arcuate hinge members to function substantially as cooperating light and weatherseal members and to provide a substantially pinch proof door.

International Classification:

B65G 6702

US Classification:

414401

Abstract:

A vehicle restraining apparatus is disclosed which is adapted to be disposed adjacent a fixed structure, such as a loading dock, for securing a vehicle adjacent the fixed structure. In a typical application, the apparatus is disposed adjacent a loading dock for restraining trucks which are backed into a position adjacent the dock during loading and unloading operations. The apparatus includes an articulated structure adapted to be deployed in a vehicle-engaging position adjacent an upright surface of the dock for engaging an adjacent vehicle. The articulated structure includes upper and lower vertically aligned pivot arms, and an actuator is provided for pivoting the upper arm upwardly in a first pivotal direction about a pivot axis substantially perpendicular to the upright surface, and pivoting the lower arm, about a second pivot axis spaced from the first axis, in a second, opposite pivotal direction, the distal end portion of the upper arm being thereby brought into engagement with a structural portion of the vehicle. In a preferred embodiment, a keeper member is mounted on the distal end portion of the upper pivot arm, the keeper member being positioned to seat in front of a horizontally-extending structural member of a vehicle, for securing the vehicle. In a preferred embodiment, the pivot arms of the articulated structure are pivotable about respectively different pivot axes extending substantially horizontally, for maintaining the keeper member in a vertical orientation.
