Abstract
A loading dock door system is disclosed. The system includes a first jamb, a second jamb positioned opposite the first jamb, a first top rail partially surrounding the first jamb, a second top rail partially surrounding the second jamb, a first door stop removably connected to the first top rail, and a second door stop removably connected to the second top rail. At least one of the first and second jambs comprises a polymer and is configured to receive a loading dock door.
Claims23
1-20. (canceled)
A loading dock door system, comprising:
- a door jamb constructed from a polymer, wherein the door jamb is configured to receive a loading dock door, and wherein the door jamb comprises a U-shaped cross-section;
- a top rail partially surrounding the door jamb;
- and
- a door stop removably connected to the top rail, wherein the door stop can be removed and repositioned on the top rail to limit how far the loading dock door can be opened or closed during operation.
The loading dock door system of claim 21, wherein the door guide is oriented at an angle relative to a longitudinal length of the top rail.
The loading dock door system of claim 21, wherein the top rail extends above the door jamb.
A loading dock door system, comprising:
- a door jamb constructed from a polymer, wherein the door jamb comprises a cross-section geometry configured to receive a loading dock door and protect the loading dock door from an impact event;
- a top rail partially surrounding the door jamb;
- and
- a door stop removably connected to the top rail, wherein the door stop can be removed and repositioned on the top rail to limit how far the loading dock door can be opened or closed during operation.
The loading dock door system of claim 31, wherein the polymer comprises a density greater than or equal to 0.90 g/cm3 and less than or equal to 2.00 g/cm3, a the tensile failure stress of 17 MPa, an elongation after fracture is greater than or equal to 300%, or a hardness greater than or equal to 40 and less than or equal to 90 Shore A, or combinations thereof.
A method of protecting a loading dock door during operation, the method comprising:
- constructing a door jamb from a polymer;
- defining a U-shaped cross-section of the door jamb, wherein the U-shaped cross-section of the door jamb is configured to receive the loading dock door;
- positioning the loading dock door within the U-shaped cross-section of the door jamb;
- partially surrounding the door jamb with a a top rail;
- and
- removably connecting a door stop to the top rail, wherein the door stop can be removed and repositioned on the top rail to limit how far the loading dock door can be opened or closed during operation.
A loading dock door system, comprising:
- a door jamb constructed from a polymer, wherein the door jamb is configured to receive a loading dock door, and wherein the door jamb comprises a U-shaped cross-section;
- a top rail partially surrounding the door jamb;
- and
- a door guide configured to guide the loading dock door into a proper position relative to the top rail as the door moves between an open position and a closed position.
