Abstract

Implementations of the present invention relate generally to systems and components for sealing and locking doors, including sliding doors for use with modular walls. A locking system can be configured to secure and release a sliding door. In particular, the locking system can include a sliding door with one or more receiving channels configured to receive a pin extending from a floor's surface. A locking mechanism can be included and configured to selectively drive a shaft to capture and release a pin that has been received by the receiving channel. The sealing system is configured to seal a gap between a modular wall and an adjacent sliding door. In particular, the sealing system can include a connector configured to connect trim to a wall panel wherein the connector includes an integrated gasket seal configured to seal the gap.

Claims (26)

1. In an architectural design environment that includes one or more modular wall systems with at least one sliding door, a locking system configured to secure and release a sliding door, the locking system comprising:

a vertical pin vertically extending from a support surface;

a sliding door comprising an edge having an elongated vertical receiving channel configured so that said vertical pin slides into and is enclosed within said elongated vertical receiving channel when said edge of the sliding door is moved into position over said vertical pin;

a shaft configured for vertical movement within said elongated vertical receiving channel; and

a locking mechanism configured to selectively lock and unlock said vertical pin within said elongated vertical receiving channel by vertically moving said shaft into engagement over said vertical pin when locking the sliding door, and by vertically moving said shaft so that said vertical pin is withdrawn from the shaft when unlocking the sliding door.

2. The system as recited in claim 1 , wherein said edge of the sliding door is a leading edge and wherein said vertical pin and elongated vertical receiving channel are configured to secure the sliding door in a closed position.

3. The system as recited in claim 1 , wherein said elongated vertical receiving channel comprises a vertical slot that forms an opening that includes chamfered edges, wherein the chamfered edges facilitate receiving said vertical pin within said elongated vertical receiving channel when the elongated vertical receiving channel slides over the vertical pin.

4. The system as recited in claim 1 , wherein the sliding door further comprises an end cap positioned at said edge of the sliding door, wherein the elongated vertical receiving channel is formed in said end cap.

5. The system as recited in claim 1 , wherein said elongated vertical receiving channel is located in a bottom portion of said edge of the sliding door and said vertical pin extends vertically upward from a said support surface, which is comprised of a floor.

6. In an architectural design environment that includes one or more modular wall systems with at least one sliding door, a sealing system configured to seal a gap between a sliding door and a modular wall panel or door frame, the sealing system comprising:

a modular wall including a doorway;

a vertical trim member;

one or more connectors attaching said trim member to said modular wall at either side of said doorway;

a sliding door coupled to the modular wall and configured to open and close the doorway, wherein the sliding door defines at least one gap between the sliding door and the modular wall that is perpendicular to the direction of travel for the sliding door; and

at least one of said one or more connectors comprising an integral gasket seal configured to seal the gaps between the modular wall and the at least one sliding door.

7. The system as recited in claim 6 , wherein the integral gasket seal of said at least one or more connectors is located on a side of said doorway which corresponds to a closed position of the sliding door.

8. The system as recited in claim 7 , wherein said at least one or more connectors and the integral gasket seal are formed using different materials.

9. In an architectural design environment that includes one or more modular wall systems with at least one sliding door, a locking system configured to secure and release a sliding door, the locking system comprising:

a vertical pin vertically extending from a support surface, the vertical pin corresponding to either a closed door or an open door position;

a sliding door comprising an elongated vertical receiving channel located in either a leading edge or a trailing edge of the sliding door, the elongated vertical receiving channel being configured so that said receiving channel slides into position over said vertical pin when the sliding door is in at least one of the open or closed door positions;

a shaft configured for vertical movement within said receiving channel; and

a locking mechanism configured to selectively lock and unlock said vertical pin within said receiving channel by vertically moving said shaft into engagement over said vertical pin when locking the sliding door, and by vertically moving said shaft so that said vertical pin is withdrawn from the shaft when unlocking the sliding door.

10. The system as recited in claim 9 , wherein said edge of the sliding door is a leading edge and wherein the vertical pin and receiving channel are configured to secure the sliding door in a closed position.

11. The system as recited in claim 9 , wherein the receiving channel comprises a vertical slot that forms an opening that includes chamfered or radiused edges, wherein the chamfered or radiused edges facilitate receiving said vertical pin within the receiving channel when the receiving channel slides over the vertical pin.

12. The system as recited in claim 11 , wherein the sliding door further comprises an end cap positioned at said leading edge of the sliding door, wherein the receiving channel is formed in said end cap.

13. The system as recited in claim 12 , wherein said receiving channel is located in a bottom portion of said leading edge of the sliding door and said vertical pin extends vertically upward from a floor, which serves as said support surface.
