Abstract
A slidable door structure adapted to move on tracks wherein one or more glide assemblies are used to resiliently mount the door. The glide assembly includes a glide body and a retention member with a spring means disposed between the two bodies. A snap fastener serves to hold the glide assembly in position so that the retention member is maintained in a fixed position while the glide body moves vertically relative to the door structure. The invention also includes an improved mullion structure and a locking device for locking and maintaining the door in an open position. Further, a substantially leak-free connection is provided between the door and wall jamb.
Claims21
A structure for use with a frame which includes top and bottom tracks, said structure being disposed within said tracks and comprising:
- at least one mullion having a channel member;
- a glide assembly disposed in the top and bottom of said mullion, each of said glide assemblies comprising:
- a glide body having a shank and a track engaging means engageable with one of said tracks for moving said mullion along said track, said shank and track engaging means extending outwardly from opposite faces of said glide body;
- a retention member which co-acts with said glide body, said retention member including an extension located at one end of said retention member and a glide body stop means located at the remaining end of said retention member;
- biasing means disposed between and contacting said glide body and said retention member for biasing said glide body relative to said retention member to permit vertical movement of said glide body relative to said member;
- said biasing means being free of contact with said mullion;
- said glide body and retention member being disposed within said channel member;
- and,
- means for fastening said retention member to said mullion to permit movement of said glide body relative to said mullion and to permit said mullion and glide assembly to travel along said tracks.
A glide assembly for use with a channel shaped mullion in a slidable door structure, said assembly comprising:
- a glide body having a shank and a track engaging means extending from opposite faces of said glide body;
- a retention member which co-acts with said glide body;
- said retention member including an extension located at one end of said retention member and a glide body stop means for restricing vertical movement of said glide body located at the remaining retention member end;
- and,
- biasing means seated between said glide body and said retention member for biasing said glide body relative to said retention member to permit vertical movement of said glide body relative to said retention member;
- said biasing means having two ends, one of said biasing means ends contacting said glide body and the remaining biasing means and contacting said retention member;
- and,
- fastening means for fastening the retention member to a mullion to permit movement of the glide body.
A glide assembly for use with a mullion in which said assembly includes:
- a glide body having a shank and a roller extending outwardly from opposite faces of said body;
- a retention member which co-acts with said glide body, said retention member including an extension located at one end of said retention member and a glide body stop means located at the remaining end of said retention member;
- a compression spring having one end thereof contacting said glide body and the remaining spring end contacting said extension;
- and means for fixing said retention member to said mullion to permit movement of said glide body.
A track locking device for use with a mullion in a slidable door structure to lock said door in an opened position on a track having a track lock engaging means thereon, said locking device including;
- a plunger housing having an opening therein;
- a plunger positioned within said plunger housing and shaped to conform to said plunger housing opening to permit substantial movement of said plunger in said opening and in one direction only;
- an end cap housing having a shape complementary to the shape of said plunger housing;
- said end cap housing being disposed on and fastened to said plunger housing;
- a biasing means disposed in said end cap housing for biasing said plunger relative to said end cap housing;
- and,
- said plunger, plunger housing, end cap housing and biasing means comprising a unitary, integral locking device adapted to be inserted in a mullion in a slidable door structure.
A mullion for use with a slidable door structure, said mullion comprising at least one extruded, one-piece integral rigid channel shaped member, said extruded one-piece member including a basewall and a pair of spaced sidewalls;
- flanges extending outward from said basewall;
- each of said sidewalls being free of grooves and having an inner sidewall glide body retaining flange and an outer sidewall flange, said outer sidewall flange and said basewall flange forming a groove adapted to receive an edge of a flexible panel member;
- said inner sidewall flanges serving as a retaining means for a glide body assembly;
- said basewall having a retention member fastening means opening;
- and,
- said basewall and sidewalls forming a channel-shaped member for receipt of a glide body and retention member.
A mullion for use with a slidable door structure, said mullion comprising at least an integral, extruded, first channel member and a second channel member inverted to said first channel member;
- each of said channel members including a base wall and a pair of sidewalls with a sidewall of said second channel member comprising a sidewall of said first channel members;
- said basewall of one of said channel members having an elongated opening extending along the basewall commencing at one end of said basewall therein for receipt of a locking device;
- said sidewalls of said channel having said basewall with an elongated opening therein, each having a pair of flanges projecting outward from said sidewall, said flanges and basewall serving as a locking device positioning means;
- and,
- said remaining channel basewall having an opening spaced from an end of said basewall for receipt of a glide assembly fastener means.
