Abstract
Abstract A replacement door which accommodates a wide variety of existing hinge spacings on a door jamb. The door includes a frame with at least one continuous hinge channel member. The channel member includes a plurality of offset sections spaced along its length. The offset sections are substantially longer than the length of commonly used hinges to thereby span the range of normally encountered hinge locations. Front and rear skins are connected to the frame with the edges of the skins being supported by the major surface of the hinge channel. Segments of the skins in an alignment with existing hinge locations may be removed to expose selected portions of the offset sections for flush mounting of the hinges. The elongated offset sections permit the use of the door structure as a common replacement for doors having a wide variety of hinge spacings.

Claim 1
Independent Claim
134 words
A door structure which accomodates hinges of a given length spaced at a wide variety of spacings on a door jamb, said door comprising: a frame including at least one continuous hinge channel member having a major outer surface, a plurality of offset sections inboard of said major surface spaced along the length of said member, said offset sections being substantially longer than the length of said hinges and spanning the range of normally encountered locations of the hinges on the door jamb, front and rear skins connected to the frame, with edges of said skins being supported by the major surface of said member whereby segments of said skins in alignment with existing hinge locations may be removed to expose selected portions of said offset sections for substantially flush mounting of the hinges.
Claim 2
Dependent Claim
134 words
A door structure which accomodates hinges of a given length spaced at a wide variety of spacings on a door jamb, said door comprising: a frame including at least one continuous hinge channel member having a major outer surface, a plurality of offset sections inboard of said major surface spaced along the length of said member, said offset sections being substantially longer than the length of said hinges and spanning the range of normally encountered locations of the hinges on the door jamb, front and rear skins connected to the frame, with edges of said skins being supported by the major surface of said member whereby segments of said skins in alignment with existing hinge locations may be removed to expose selected portions of said offset sections for substantially flush mounting of the hinges.
Claim 3
Dependent Claim
23 words
The door of claim 1 wherein said offset sections are at least 50% longer in length than the given lengths of said hinges.
Claim 4
Dependent Claim
