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 trim member, a bottom sill, and side jambs connected between the top trim member and the bottom sill;
a primary sliding panel secured in the door frame and slidably displaceable linearly from a closed position to a first open position and linearly from the first open position to a second open position;
a secondary sliding panel secured in the door frame and slidably displaceable linearly between the first open position and the second open position; and
an interlock mechanism that locks the secondary sliding panel to the bottom sill until the primary sliding panel is displaced from the closed position to the first open position, the interlock mechanism locking the secondary sliding panel to the primary sliding panel when the primary sliding panel is displaced to and beyond the first open position to the second open position.

2. The sliding door assembly according to claim 1 , wherein the interlock mechanism is configured to detach the secondary sliding panel from the primary sliding panel and re-lock the secondary sliding panel to the bottom sill when the primary sliding panel is displaced from the second open position to the first open position and beyond the first open position to the closed position.

3. The sliding door assembly according to claim 1 , wherein the interlock mechanism comprises:
a first interlock cam block fixed to the primary sliding panel;
a second interlock cam block fixed to the bottom sill; and
an interlock assembly fixed to the secondary sliding panel,
wherein when the primary sliding panel is between the closed position and the first open position, the interlock assembly is secured to the second interlock cam block and the secondary sliding panel is fixed in place, and in the first open position, the first interlock cam block engages the interlock assembly, detaches the secondary sliding panel from the second interlock cam block, and secures the interlock assembly to the first interlock cam block.

4. The sliding door assembly according to claim 3 , wherein the interlock assembly comprises an interlock cam and a pair of interlock triggers, and wherein the interlock cam comprises a first cam tab and a second cam tab,
wherein one of the interlock triggers engages the interlock cam when the primary sliding panel is between the closed position and the first open position to secure the first cam tab to the second interlock cam block, and
wherein the one of the interlock triggers is disposed in a path of the first interlock cam block such that in the first open position, the first interlock cam block engages the one of the interlock triggers and displaces the one of the interlock triggers from engagement with the interlock cam.

5. The sliding door assembly according to claim 4 , wherein in the first open position, the second cam tab engages the first interlock cam block.

6. The sliding door assembly according to claim 4 , wherein the interlock triggers comprise an upper part and a lower part secured on a common pivot axis.

7. The sliding door assembly according to claim 6 , wherein the upper part comprises a top trigger tab in the path of the first interlock cam block and a lock tab that selectively engages the interlock cam.

8. The sliding door assembly according to claim 7 , wherein the lower part comprises a bottom trigger tab engageable with the second interlock cam block and a bottom lock tab that selectively engages the interlock cam.

9. The sliding door assembly according to claim 8 , further comprising a spring that biases the interlock triggers toward engagement with the interlock cam.

10. The sliding door assembly according to claim 1 , further comprising a door handle cooperable with the primary sliding panel and a brake mechanism cooperable with the door handle, wherein the brake mechanism is configured to hold the primary sliding panel in place until the door handle is actuated to disengage the brake mechanism.

11. The sliding door assembly according to claim 10 , wherein the brake mechanism is configured to re-engage when the door handle is released.

12. The sliding door assembly according to claim 10 , wherein the brake mechanism comprises:
a rod coupled with the handle and displaceable with the handle;
a collar fixed to the rod and displaceable with the rod;
a moving block disposed over the rod and engaging the collar;
a brake slide fixed to the moving block and displaceable with the moving block; and
a brake pad cooperable with the brake slide and displaceable by the brake slide between an engaged position and a disengaged position.

13. The sliding door assembly according to claim 12 , wherein the brake mechanism further comprises:
a fixed block secured to the door frame, wherein the rod extends through the fixed block, and wherein the fixed block is positioned above the moving block; and
a spring positioned between the fixed block and the moving block, the spring biasing the moving block toward a position in which the brake pad is in the engaged position.

14. The sliding door assembly according to claim 13 , wherein the brake mechanism further comprises an H-bar pivotably coupled at one end to the brake slide and at an opposite end to a brake pivot arm, wherein the brake pad is fixed to the brake pivot arm.

15. The sliding door assembly comprising:
a door frame including a top trim member, a bottom sill, and side jambs connected between the top trim member and the bottom sill;
a primary sliding panel secured in the door frame;
a door handle cooperable with the primary sliding panel; and
a brake mechanism cooperable with the door handle, wherein the brake mechanism is biased toward a brake engaged position by a spring to hold the primary sliding panel in place until the door handle is actuated against a bias force of the spring to disengage the brake mechanism.

16. The sliding door assembly according to claim 15 , further comprising a secondary sliding panel secured in the door frame and an interlock mechanism that locks the secondary sliding panel to the bottom sill until the primary sliding panel is displaced from a closed position to a first open position.

17. The sliding door assembly according to claim 15 , wherein the brake mechanism comprises:
a rod coupled with the door handle and displaceable with the door handle;
a collar fixed to the rod and displaceable with the rod;
a moving block disposed over the rod and engaging the collar;
a brake slide fixed to the moving block and displaceable with the moving block; and
a brake pad cooperable with the brake slide and displaceable by the brake slide between an engaged position and a disengaged position.

18. The sliding door assembly according to claim 17 , wherein the brake mechanism further comprises:
a fixed block secured to the door frame, wherein the rod extends through the fixed block, and wherein the fixed block is positioned above the moving block,
wherein the spring is positioned between the fixed block and the moving block.
