Abstract
A door having a plurality of channel-shaped frame members encircling a core and being coupled to one another by interfitting dimples and projections at the confronting ends of adjacent frame members. On opposite sides of the core are panels having lips which are accommodated in grooves formed in the frame members. The components of the door may be assembled without the need for any tools and such components may be maintained in assembled condition without the use of separate fastening devices such as bolts, nails, screws, and the like, or any fixtures or measuring devices.
Claims17
A door construction comprising
- a plurality of individual frame members having mitered ends abutting one another and assembled to form a frame,
- each of said frame members having parallel flanges joined to and spaced by a web,
- each of said flanges having at its ends an extension,
- the extension of one of said flanges overlying the extension of the corresponding flange of the confronting frame member,
- the flanges being configured to form a groove at the junction of said web with each of said flanges;
- a pair of panel members positioned on opposite sides of said frame,
- each of said panel members having a body portion spanning said frame members and terminating at a plurality of its edges in lips accommodated in said grooves;
- and
- coupling means at the abutting ends of each of said frame members coupling said frame members to one another and maintaining said frame members assembled,
- said coupling means being carried by said extensions.
A door construction comprising
- a first pair of individual uniform length frame members;
- a second pair of individual uniform length frame members,
- the length of the frame members of said first pair being less than the length of the frame members of said second pair,
- opposite ends of each of said first pair of frame members confronting and being assembled with opposite ends of each of said second pair of frame members, thereby forming a rectangular frame;
- cooperable coupling means at opposite ends of each of said frame members and engaging one another for maintaining all of said frame members assembled,
- each of said frame members having a pair of spaced, parallel flanges joined by a web,
- each of the flanges of each of said frame members having an extension extending beyond said flange,
- said coupling means being carried by said extensions,
- the juncture of said web with each of said flanges forming a groove;
- and
- a pair of spaced apart, parallel panels each of which spans all of said frame members on opposite sides of said frame,
- each of said panels terminating at selected ones of its edges in lips accommodated in said grooves.
A door construction comprising
- a plurality of individual frame members joined to one another and forming a quadrangular frame,
- each of said frame members having a pair of parallel flanges joined to and spaced apart by a web,
- the flanges of adjacent ones of said frame members having mitered ends abutting one another,
- each of said flanges having an extension projecting beyond its mitered end,
- the extensions at the abutting ends of adjacent ones of said flanges overlapping one another;
- cooperable coupling means carried by said extensions and securing said frame members to one another;
- a quadrangular core member having an area corresponding substantially to that of said frame with its marginal edges accommodated between the flanges of said frame members;
- a pair of panel members,
- each of said panel members having a body portion overlying said core member and spanning all of said frame members;
- and
- means securing said panel members to said frame members on opposite sides of said frame.
