Abstract

A sliding door assembly of the type at least partially formed from extruded material components wherein the assembly includes at least one movable panel and one stationary or fixed panel. The door assembly includes a lock assembly structured and positioned to be interconnected between portions of the two panels to prevent relative movement therebetween. Both of the panels are supported on a track assembly incorporating various components including a removable, snap-in threshold and a similarly removable track runner for support of the movable panels thereon.

Claims

1. A sliding door assembly of the type including at least a stationary panel and a movable panel, said door assembly comprising:

(a) a track assembly extending across a doorway and formed at least in part from extruded material and disposed in supporting relation to said panels,

(b) both said stationary and movable panels comprising an interlocking rail defining a lateral peripheral portion of each panel,

(c) said interlocking rails correspondingly configured and including a mating portion each of which is disposed in substantially mating engagement with one another when said panels are disposed in a closed position along the length of said track assembly,

(d) each mating portion comprising two flange elements spaced outwardly from a remainder of said respective interlocking rail and in offset, non-coplanar, spaced apart relation to one another, said two flange element of each interlocking rail extending outwardly in a common direction,

(e) said flange element of each interlocking rail being reversely oriented and disposed in parallel, substantially overlapping relation to correspondingly disposed flange elements of the other of said interlocking rails when said panels are disposed in said closed position,

(f) a lock assembly mounted on one of said interlocking rails and including a rod element rotatable about its own longitudinal axis and including a distal end portion transversly oriented relative to a length of said rod element and rotatable therewith,

(g) said rod element extending into said one interlocking rail in substantially underlying relation to one flange element thereof, said distal end dimensioned and disposed for selective positioning into and out of blocking engagement with a correspondingly positioned and overlapping flange of the other of said interlocking rails, when said panels are in said closed position, upon rotation of said rod element, and whereby relative movement between said panels out of said closed position is prevented when said distal end is in said blocking position.

2. A sliding door assembly as in claim 1 wherein said track assembly comprises a threshold portion having an elongated configuration and being disposed to extend from an edge of said stationary panel along a length of said track assembly to substantially the opposite end thereof, said threshold portion mounted substantially in a middle portion of said track assembly between opposite longitudinal peripheral edges thereof and extending parallel to said movable panel, said threshold portion including depending fingers being integrally formed along the length of opposite peripheral edges of said threshold portion and being flexible relative to the remainder of said threshold portion, said finger structured for snap-lock and removable attachment to said track assembly.

3. A sliding door assembly as in claim 2 wherein said track assembly comprises an elongated channel extending from an edge of said stationary panel to the opposite end of said track assembly, said channel including a flange mounted on each of two inner wall surfaces and extending inwardly therefrom towards a center of said channel, said threshold portion removably mounted within said channel and said depending fingers disposed in removable and substantially fitted engagement with respective ones of said inwardly directed flanges.

4. A sliding door assembly as in claim 1 wherein said track assembly comprises a threshold portion disposed to extend from an edge of said stationary panel along a length of the track assembly to substantially the opposite end thereof, said threshold portion including oppositely disposed depending fingers flexibly attached in spaced apart relation to the remainder of said threshold portion, said fingers structured for a snap-lock and removable attachment to said track assembly.

5. A sliding door assembly as in claim 1 wherein said track assembly includes a track runner mounted thereon and disposed to extend along a length of said track assembly in supporting relation to said movable panel, a roller assembly attached to the undersurface of said movable panel and movably engaging the upper peripheral edge of said track runner, whereby said movable panel is slidable along said track assembly supported on said track runner.

6. A sliding door assembly as in claim 5 wherein said track runner protrudes upwardly from said track assembly and comprises flexibly structured and secured sidewall portions configured for snap-lock and removable attachment along a length of said track assembly.

7. A sliding door assembly as in claim 1 further comprising jamb means formed from an extruded material and disposed to define a peripheral supporting component for remaining portions of said door assembly and including a mounting channel integrally formed on said jamb means and disposed and configured for mounting dry wall material therein, said mounting channel extending along a predetermined length of said jamb means, whereby wall structure of a dwelling in which said door assembly is mounted may be secured directly to integral portions of said door assembly.
