Abstract

A sliding door assembly includes a door frame with a top trim member, a bottom sill, and side jambs connected between the top trim member and the bottom sill, and a primary sliding panel secured in the door frame. The top trim member includes a track configured to support a weight of the primary sliding panel and prevent the primary sliding panel from coming off the track. Other features include an interlock mechanism to limit relative movement using multiple sliding doors and a brake mechanism to secure the doors in position when the door handle is released. A drop window includes features to accommodate for manufacturing tolerances and box frame assemblies that are out of square.

First claim

The invention claimed is:

1 . A sliding door assembly comprising:
a door frame including a top header, a bottom sill, and side jambs connected between the top header and the bottom sill; a primary sliding panel secured in the door frame and including a top panel trim member, the top panel trim member defining a cavity; a primary rail extrusion fixed to the top header, the primary rail extrusion including a top rail and a bottom rail; a primary truck connected between the primary rail extrusion and the primary sliding panel, the primary truck being substantially U-shaped and disposed at least partly in the cavity of the top panel trim member; a primary roller fixed to the primary truck and secured in rolling engagement with the bottom rail; and at least one seal positioned between the primary truck and the primary rail extrusion, wherein the primary roller is fixed to one leg of the substantially U-shaped truck, and wherein at least a portion of the seal is connected to an opposite leg of the U-shaped truck, wherein the bottom rail of the primary rail extrusion is configured to support a weight of the primary sliding panel, and wherein the top rail of the primary rail extrusion is cooperable with the primary roller and configured to prevent the primary sliding panel from assuming an off-track position.

2 . The sliding door assembly according to claim 1 , wherein the primary roller comprises a concave rolling surface.

3 . The sliding door assembly according to claim 2 , wherein the bottom rail is convex shaped in complement to the concave rolling surface, the top rail being disposed at least partially within an area defined by the concave rolling surface.

4 . The sliding door assembly according to claim 1 , wherein the primary truck is connected to the primary panel via a rivet nut and a hanger bolt.

5 . The sliding door assembly according to claim 1 , further comprising a secondary sliding panel secured in the door frame.

6 . The sliding door assembly according to claim 5 , further comprising:
a secondary rail extrusion fixed to the top header, the secondary rail extrusion including a top rail and a bottom rail; a secondary truck connected between the secondary rail extrusion and the secondary sliding panel; and a secondary roller fixed to the secondary truck and secured in rolling engagement with the bottom rail.

7 . The sliding door assembly according to claim 6 , wherein the primary rail extrusion and the secondary rail extrusion are fixed to the top header side by side.

8 . The sliding door assembly according to claim 1 , wherein a height of the primary sliding panel in the door frame is adjustable.

9 . The sliding door assembly according to claim 1 , wherein the top panel trim member is secured to the primary truck via a bolt, wherein rotation of the bolt adjusts a position of the primary sliding panel relative to the top header.

10 . A sliding door assembly comprising:
a door frame including a top header, a bottom sill, and side jambs connected between the top header and the bottom sill; a sliding panel secured in the door frame and including a top panel trim member; a rail extrusion fixed to the top header, the rail extrusion including a top rail and a bottom rail; a truck connected to the top panel trim member and positioned between the rail extrusion and the top panel trim member; and a roller fixed to the truck and secured in rolling engagement with the bottom rail, wherein the top panel trim member is substantially U-shaped such that the truck extends at least partially into the U-shape and such that legs of the U-shape are at least partially disposed on opposite sides of the truck, wherein the truck is substantially U-shaped with the bottom of the U-shape disposed in the U-shape of the top panel trim member, one leg of the U-shape securing the roller, and an opposite leg of the U-shape securing a seal between the truck and the rail extrusion, wherein the primary roller comprises a concave rolling surface, and wherein the bottom rail is convex shaped in complement to the concave rolling surface, the top rail being disposed at least partially within an area defined by the concave rolling surface.

11 . The sliding door assembly according to claim 10 , wherein a rivet nut extends through a bottom of the truck and is connected to the top panel trim member via a hanger bolt.

12 . The sliding door assembly according to claim 11 , wherein the sliding panel is height adjustable via the hanger bolt and a jam screw.

13 . The sliding door assembly according to claim 12 , wherein the jam screw is threaded into the truck and is accessible via a hole in the top panel trim member.

14 . The sliding door assembly according to claim 11 , wherein the top panel trim member comprises upper flanges at ends of the U-shape that each include a T-slot configured to receive a glide and/or seal.

15 . The sliding door assembly according to claim 10 , wherein glass for the sliding panel is secured to the top panel trim member via an adhesive.

16 . The sliding door assembly according to claim 10 , further comprising a bottom trim member secured at a bottom of the sliding panel, wherein the bottom sill comprises a rail over which the bottom trim member is positioned, and wherein a height of the rail spans a height adjustment range for the sliding panel.

17 . The sliding door assembly according to claim 16 , wherein the bottom trim member comprises T-slots facing the rail in which glides and/or seals are disposed and engage opposite sides of the rail.

18 . The sliding door assembly according to claim 10 , further comprising a drop window, the drop window comprising:
a window panel movably secured in the door frame, the window panel being displaceable between a closed position and an open position; a motor; a track; a carriage coupled with the track; and a coupling connecting the motor and the window panel, the coupling including top and bottom plates connected to the motor and the carriage, and the coupling including a center plate connected to the window panel.

19 . A sliding door assembly comprising:
a door frame including a top header, a bottom sill, and side jambs connected between the top header and the bottom sill; a sliding panel secured in the door frame and including a top panel trim member; a rail extrusion fixed to the top header, the rail extrusion including a top rail and a bottom rail; a truck connected to the top panel trim member and positioned between the rail extrusion and the top panel trim member; and a roller fixed to the truck and secured in rolling engagement with the bottom rail, wherein the top panel trim member is substantially U-shaped such that the truck extends at least partially into the U-shape and such that legs of the U-shape are at least partially disposed on opposite sides of the truck, wherein a rivet nut extends through a bottom of the truck and is connected to the top panel trim member via a hanger bolt, wherein the sliding panel is height adjustable via the hanger bolt and a jam screw, and wherein the jam screw is positionable to engage and stabilize the truck and the top panel trim member regardless of a height setting of the sliding panel by the hanger bolt, the jam screw serving to secure the truck and the top panel trim member in place.
