Abstract
A sliding door is secured to one side of a wall or partition panel having a door opening, and includes a trolley that is held in a track located above the door opening. The wheels or rollers of the trolley move along the track when the door is moved to a closed position until the roller contacts a wedge or ramp associated with the track. The wedge urges the roller inwardly toward the wall or partition panel, such that when the door is in the fully closed position, the trolley is positioned inwardly on the track to move the upper area of the door into engagement with the wall or partition panel. The lower end of the door includes a channel within which is positioned a follower attached to a swing arm, which simultaneously draws the lower end of the door into engagement with the wall or panel.
Claims19
A sliding door assembly for selectively closing a door opening in a vertical surface, comprising:
- a door;
- a door track that extends transverse to the vertical surface, wherein the door track defines a path of travel for the door for movement between an open position and a closed position, and wherein the door track includes a first track portion and a second track portion laterally offset from the first track portion along the path of travel;
- and
- a doorstop associated with the door track and configured to direct the door laterally from the first track portion to the second track portion in engagement with the vertical surface when the door is moved from the open position toward the closed position.
A sliding door system, comprising:
- a door sized to close an opening formed in a structure and having a trolley device connected thereto;
- a door retention track connected to the structure, the door retention track configured to hold the trolley device and provide a surface along which the trolley device may travel so as to move the door between open and closed positions;
- and
- a laterally facing ramp positioned in the door retention track and configured to force the door laterally against the structure when the door is moved to the closed position.
A wall and door system comprising:
- a wall having a pair of vertical surfaces and a transverse surface collectively defining an opening;
- a door track associated with an opening side of the transverse surface;
- a door slidably retained by the door track, the door having at least one trolley device mounted to an upper area thereof and held by the door track;
- and
- means associated with the door track and the trolley device for moving the door laterally into engagement with the pair of vertical surfaces when the door closes the opening.
