Problems solved by technology

Traditionally, bi-fold or half doors have been made of wood, but the expense of wood has caused the industry to search for other suitable materials.
However, the injection molding process is limited in its application.
Such a door is unsuited for general applications in the home or office.
One of the main problems with full length doors made from injection molded plastic is their lack of rigidity.
Additionally, the finished product manufactured from plastic does not require painting and is a solid color throughout so scratches from ordinary use are not readily visible.

Embodiment Construction

[0014] The invention is directed to a full length bi-fold and half door constructed from synthetic resinous, rigid plastic that is extruded to form the various pieces used to make the door. Rigid plastic has the advantage of being lighter in weight than wood because the interior of the rails, stiles, and vanes are basically hollow except for the reinforcing cross-members that are formed during the extruding process. This type of construction offers several advantages over wood. A rigid plastic door is much more fire resistant than wood, and it does not warp from humidity. Additionally, the finished product manufactured from plastic does not require painting and is a solid color throughout so scratches from ordinary use are not readily visible. Finally, plastic is easier to clean, can be produced with a glossy finish, and is generally more durable than wood.

[0015] FIG. 1 and FIG. 2 show the preferred embodiment of the invention wherein extruded rigid plastic bi-fold and half doors ha...

Abstract

Extruded plastic doors having two side stiles and a top and bottom rail forming a generally rectangular configuration and having horizontal vanes covering the interior of the door. The stiles have mating indentations along their interior edge for receiving the vanes and holding the vanes in a permanently fixed position relative to the stiles and rails when the stiles and rails are assembled into a rectangular configuration. The stiles, rails and vanes are formed by an extrusion process so as to have a substantially hollow interior with reinforcing cross-members.

Description

[0001] Not applicable.[0002] Not applicable.[0003] 1. Field of the Invention[0004] This invention relates to doors made from extruded plastic. More specifically, it relates to bi-fold or half doors made from rigid plastic, such as polyvinyl chloride (PVC). The side stiles, horizontal rails, and slatted vanes that make up the door are individual pieces that are generally hollow, except for reinforcing interior cross-members. The individual pieces are formed by extruding plastic through a die. The invention contemplates that the door be assembled in a manner similar to that used for a conventional wooden bi-fold door.[0005] 2. Description of the Related Art[0006] Traditionally, bi-fold or half doors have been made of wood, but the expense of wood has caused the industry to search for other suitable materials. Recently, manufacturers have turned to fabricating such doors from synthetic resins by injection molding, as described in U.S. Pat. No. 3,985,175. However, the injection molding ...
