Structural unit, specifically a door including an injected molded frame
First Claim
1. A structural unit comprising a frame formed of molded synthetic polymeric/copolymeric plastic material, said frame being defined by a peripheral wall and relatively spaced inwardly projecting inner and outer walls terminating in respective terminal edges, said inner and outer wall terminal edges defining respective inner and outer openings, said inner opening being larger than said outer opening, an insert, said insert having a peripheral edge of a size to pass through said inner opening along a path substantially parallel to an axis of said inner opening but of a size too large to pass through said outer opening, said insert being located in a plane between said inner and outer walls, means for holding said insert in said frame, an access area through which said holding means is slid along a path of travel substantially normal to said inner opening axis into sandwiched relationship between said insert and said inwardly projecting inner wall, and means for retaining said holding means in the sandwich relationship thereof.

Abstract
A door includes a U-shaped frame having opposing side channels. The channels include peripheral, inner and outer walls with the inner wall being of a larger size and configuration than the outer wall. A glass insert slightly smaller than the size of the inner wall is inserted therethrough and is guided to a centered position seated upon the outer wall. An open frame insert is slid into the two side channels, and a plurality of opposing pairs of walls deflect the open frame insert into bearing engagement with the glass insert. A peripheral edge of the open frame insert defines a peripheral channel with a terminal edge of the door frame inner wall for receipt therein of a peripheral securing boss of an elastomeric peripheral seal.

- 1. A structural unit comprising a frame formed of molded synthetic polymeric/copolymeric plastic material, said frame being defined by a peripheral wall and relatively spaced inwardly projecting inner and outer walls terminating in respective terminal edges, said inner and outer wall terminal edges defining respective inner and outer openings, said inner opening being larger than said outer opening, an insert, said insert having a peripheral edge of a size to pass through said inner opening along a path substantially parallel to an axis of said inner opening but of a size too large to pass through said outer opening, said insert being located in a plane between said inner and outer walls, means for holding said insert in said frame, an access area through which said holding means is slid along a path of travel substantially normal to said inner opening axis into sandwiched relationship between said insert and said inwardly projecting inner wall, and means for retaining said holding means in the sandwich relationship thereof.
- 40. A structural unit comprising a frame formed of molded synthetic polymeric/copolymeric plastic material, said frame being defined by a peripheral wall and relatively spaced inwardly projecting inner and outer walls terminating in respective terminal edges, said inner and outer wall terminal edges defining respective inner and outer openings, said inner opening being larger than said outer opening, an insert, said insert having a peripheral edge of a size to pass through said inner opening along a path substantially parallel to an axis of said inner opening but of a size too large to pass through said outer opening, said insert being located in a plane between said inner and outer walls, means for holding said insert in said frame, an access area through which said holding means is slid along a path of travel substantially normal to said inner opening axis into sandwiched relationship between said insert and said inwardly projecting inner wall, and means for closing said access area.
- 50. A structural unit comprising a frame formed of molded synthetic polymeric/copolymeric plastic material, said frame being defined by a peripheral wall and relatively spaced inwardly projecting inner and outer walls terminating in respective terminal edges, said inner and outer wall terminal edges defining respective inner and outer openings, said inner opening being larger than said outer opening, an insert, said insert having a peripheral edge of a size to pass through said inner opening along a path substantially parallel to an axis of said inner opening but of a size too large to pass through said outer opening, said insert being located in a plane between said inner and outer walls, means for holding said insert in said frame, an access area through which said holding means is slid along a path of travel substantially normal to said inner opening axis into sandwiched relationship between said insert and said inwardly projecting inner wall, a peripheral seal, and means for retaining said peripheral seal in peripheral bounding relationship to said frame.
- 56. A structural unit comprising a frame formed of molded synthetic polymeric/copolymeric plastic material, said frame including a pair of spaced corners each having a wall portion, at least one opening in each wall portion for receiving a fastener therethrough and at least an additional opening in each wall portion for receiving a pivot pin, said one and additional openings being substantially identically located at their respective corners, a cooperative fastener having an opening for receiving the first-mentioned fastener incident to securing a pivot plate selectively to one of said corners for selective right-hand/left-hand opening movement of the structural unit relative to an access opening of an associated structure, and means for locating the cooperative fastener relative to either of the at least one openings.
- 64. A structural unit comprising a frame formed of molded synthetic polymeric/copolymeric plastic material, said frame being defined by a peripheral wall and relatively spaced inwardly projecting inner and outer walls terminating in respective terminal edges, said inner and outer wall terminal edges defining respective inner and outer openings, said inner opening being larger than said outer opening, an insert, said insert having a peripheral edge of a size to pass through said inner opening along a path substantially parallel to an axis of said inner opening but of a size too large to pass through said outer opening, said insert being located in a plane between said inner and outer walls, means for holding said insert in said frame, an access area through which said holding means is slid along a path of travel substantially normal to said inner opening axis into sandwiched relationship between said insert and said inwardly projecting inner wall, means for closing said access area, and means for pivotally mounting said frame relative to an opening of an associated structure.
-
65. The structural unit as defined in claim 65 wherein said frame is of a substantially polygonal configuration, and said frame pivotally mounting means are disposed in two pairs for effecting selective pivoting movement of said frame about either one of two substantially parallel pivot axes.
