Abstract

The lock assemblies as described herein engage with keepers on movable sashes and include features designed to provide additional sealing functions to the lock assembly by incorporating a ribbon seal within a catch housing of the lock assembly.

First claim

The invention claimed is:

1. A lock assembly for releasably locking a sash component in a closed position with respect to a frame component, the assembly comprising:
a keeper on the sash component;
a catch housing attached to the frame component, wherein the catch housing defines a ribbon seal path through the catch housing;
a catch located in the catch housing, the catch movable within the catch housing between locked and unlocked positions, the catch configured to engage the keeper when the catch is in the locked position and the sash component is in a closed position; and
a ribbon seal located in the catch housing, wherein the ribbon seal is positioned in the ribbon seal path, and wherein the ribbon seal is operably connected to the catch, such that movement of the catch between the locked and unlocked positions moves ribbon seal through the ribbon seal path.

2. An assembly according to claim 1 , wherein the ribbon seal slides along the ribbon seal path as the catch moves between the locked and unlocked positions.

3. An assembly according to claim 1 , wherein the ribbon seal path comprises a serpentine curved path.

4. An assembly according to claim 1 , wherein the ribbon seal path comprises a serpentine curved path comprising three curves.

5. An assembly according to claim 1 , wherein at least a portion of the ribbon seal path is defined by one or more walls within the catch housing.

6. An assembly according to claim 1 , wherein at least a portion of the ribbon seal path is defined by one or more posts within the catch housing.

7. An assembly according to claim 1 , wherein the catch housing comprises a base and a cover, and wherein the ribbon seal path is defined in the base and/or the cover.

8. An assembly according to claim 7 , wherein at least a portion of the ribbon seal path comprises a slot formed between two opposing walls attached to the base.

9. An assembly according to claim 1 , wherein the ribbon seal comprises an opening formed through the ribbon seal, and wherein the catch extends through the opening.

10. An assembly according to claim 1 , wherein the catch rotates about a catch axis when the catch moves between the locked and unlocked positions, and wherein the catch comprises a catch lever comprising a free end located distal from the catch axis, and further wherein the ribbon seal is located between the free end of the catch lever and the catch axis.

11. An assembly according to claim 1 , wherein the ribbon seal comprises visible indicia configured to indicate whether the catch is in the locked or unlocked position.

12. An assembly according to claim 11 , wherein the visible indicia comprises two or more different colors on the ribbon seal.

13. An assembly according to claim 11 , wherein the visible indicia comprises two or more areas of different reflectivity on the ribbon seal.

14. An assembly according to claim 1 , the assembly further comprising a switch configured to provide an indication that the catch is in the locked or unlocked position.

15. An assembly according to claim 14 , wherein the switch comprises a sensor configured to detect the position of the ribbon seal in the ribbon seal path.

16. An assembly according to claim 14 , wherein the switch comprises a light that is configured to emit light to indicate that the catch is in one of the locked and unlocked positions.

17. An assembly according to claim 14 , wherein the switch is configured to provide a signal to an external control device, wherein the signal is indicative of whether the catch is in the locked or unlocked position.

18. An assembly according to claim 1 , wherein the assembly further comprises a motor operably connected to the ribbon seal and configured to move the ribbon seal within the ribbon seal path, wherein the motor and the ribbon seal are configured to move the catch between the locked and unlocked positions.

19. A lock assembly for releasably locking a sash component in a closed position with respect to a frame component, the assembly comprising:
a keeper on the sash component;
a catch housing attached to the frame component, wherein the catch housing defines a ribbon seal path through the catch housing, wherein the ribbon seal path comprises a serpentine curved path;
a catch located in the catch housing, the catch movable within the catch housing between locked and unlocked positions, the catch configured to engage the keeper when the catch is in the locked position and the sash component is in a closed position, wherein the catch rotates about a catch axis when the catch moves between the locked and unlocked positions; and
a ribbon seal located in the catch housing, wherein the ribbon seal is positioned in the ribbon seal path, and wherein the ribbon seal is operably connected to the catch, such that movement of the catch between the locked and unlocked positions slides the ribbon seal along the ribbon seal path;
wherein the catch comprises a catch lever comprising a free end located distal from the catch axis, and further wherein the ribbon seal is located between the free end of the catch lever and the catch axis.

20. An assembly according to claim 19 , wherein the ribbon seal comprises an opening formed through the ribbon seal, and wherein the catch extends through the opening.

21. A method of closing an opening in a lock assembly for releasably locking a sash component, the method comprising:
moving a catch within a catch housing between locked and unlocked positions, wherein the catch engages a keeper on a sash component when the catch is in the locked position and the sash component is in a closed position; and
moving a ribbon seal through a ribbon seal path in the catch housing when moving the catch between the locked and unlocked positions, wherein the catch is operably engaged with the ribbon seal.

22. A method according to claim 21 , wherein moving the ribbon seal comprises sliding the ribbon seal along the ribbon seal path.

23. A method according to claim 21 , wherein moving the ribbon seal comprises sliding the ribbon seal along a serpentine curved ribbon seal path.

24. A method according to claim 21 , wherein moving the catch between the locked and unlocked positions comprises rotating the catch about a catch axis, and wherein the catch comprises a catch lever comprising a free end located distal from the catch axis, and further wherein the ribbon seal is located between the free end of the catch lever and the catch axis.

25. A method according to claim 24 , the method further comprising providing a visual indication that the catch is in the locked or unlocked position by providing visible indicia on the ribbon seal.
