Abstract

An insertable roll-up door for a vehicle is formed from a header, left and right guide members and, optionally, a bottom sill. These components are assembled at a first geographic location to form a dimensionally stable subassembly. A flexible door panel is connected with a roller and installed in the subassembly where ends of the roller are received at top portions of the guide members and supported to rotate about a roller axis to wind the door panel onto and off from the roller. Edges of the door panel are guided by the guide members to move vertically to open and close the door. The assembled door is shipped to a second location to be installed on a vehicle. At the second location, an opening is created in the vehicle sized to receive the door. The door is inserted in the opening and fixed to the vehicle with fasteners.

Dependent claims

A method of installing a roller door on a vehicle, the method comprising:

forming a roller door subassembly at a first geographical location prior to connecting the subassembly with the vehicle, the step of forming comprising:
providing a header;
providing left and right guide members, wherein each of the guide members comprise respective left and right top portions, wherein the left guide member comprises a left flange extending leftward from the subassembly and wherein the right guide member comprises a right flange extending rightward from the subassembly, and wherein the left and right top portions comprise respective left and right roller receivers;
connecting the guide members with the header to form the roller door subassembly as a unitary structure, wherein the guide members are substantially parallel with one another and wherein both guide members are substantially perpendicular with the header;
packaging the roller door subassembly at the first location
installing the door at a second geographic location, the step of installing comprising:
creating an opening in a wall of the vehicle;
receiving the packaged roller door subassembly at the second geographic location;
unpackaging the subassembly at the second geographic location;
forming the roller door on the roller door subassembly at the second location, the step of forming comprising:
providing left and right receiving slots along vertical portions of the respective left guide member and right guide member;
providing a roller and a flexible door panel, the roller having left and right ends and being rotatable about a roller axis, wherein the door panel is connected with the roller at a top end of the door panel and wherein rotation of the roller about the axis winds and unwinds the door panel onto and off from the roller;
engaging the left and right ends of the roller with respective left and right roller receivers;
and
inserting left and right edges of the door panel into respective left and right receiving slots, wherein a downward force applied to the door panel causes the door panel to unwind from the roller and extend downward along the guides,
inserting the roller door into the opening, wherein the left flange and the right flange contact an outer surface of the wall;
and
fixing the header, the left guide member, and the right guide member with the wall.

connecting the guide members with the header to form the roller door subassembly as a unitary structure, wherein the guide members are substantially parallel with one another and wherein both guide members are substantially perpendicular with the header;
forming the roller door on the roller door subassembly at the first location, comprising the steps of:
providing left and right receiving slots along vertical portions of the respective left guide member and right guide member;
providing a roller and flexible door panel, the roller having left and right ends and being rotatable about a roller axis, wherein the door panel is connected with the roller at a top end of the door panel and wherein rotation of the roller about the axis winds and unwinds the panel onto and off from the roller;
engaging the left and right ends of the roller with respective left and right roller receivers;
and
inserting left and right edges of the door panel into receiving slots of the left and right guides, wherein a downward force applied to the door panel causes the door panel to unwind from the roller and extend downward along the guides;
packaging the roller door at the first location;
and
installing the door at a second geographic location, the step of installing comprising:
creating an opening in a wall of the vehicle;
receiving the packaged roller door at the second geographic location;
unpackaging the roller door at the second geographic location;
inserting the roller door into the opening, wherein the left flange and the right flange contact an outer surface of the wall;
and
fixing the header, the left guide member, and the right guide member with the wall.
