Abstract
A sliding door having an improved handle and lock assembly associated therewith. The assembly enables a closed and locked sliding door to be unlocked and opened by manual application of a single-motion to the door handle, such as a substantially horizontally-directed force applied to the door handle in the opening direction to effect unlocking of the door followed by movement of the sliding door into an open position.
Claims19
An openable and closable sliding door arrangement for a doorway, comprising:
- an upright door positioned for generally horizontal and rectilinear sliding movement between opened and closed positions relative to an upright doorway defined by a stationary structure, said door defining inside and outside surfaces on opposite sides thereof;
- a locking mechanism supported on the door for movement between locking and unlocking positions, said locking mechanism including a locking member supported on the door for pivoting movement about a generally horizontal axis which extends transverse to the door, and a locking bolt arrangement which cooperates with and is movably displaced in response to pivoting of the locking member between said unlocking and locking positions, said locking bolt arrangement having an end portion which projects outwardly beyond the door when in said locking position for engagement with an adjacent retainer structure which is fixed to the stationary structure when the door is in the closed position;
- a manually accessible lock actuator mounted on said door adjacent said inside surface thereof and interconnected to said locking member for permitting manual pivoting thereof into the locking position;
- and
- an activating handle adjacent said inside surface in the vicinity of said lock actuator for controlling opening and closing sliding movement of said door, said activating handle being movably supported on said door for movement through a small generally horizontal distance in a direction generally parallel with the opening and closing directional movement of the door, and a motion transfer mechanism connected between the activating handle and the locking member so that manual movement of the activating handle relative to the door in the door-opening direction causes pivoting movement of the locking member to effect release of the locking bolt arrangement with continued application of a generally horizontally oriented opening force to the handle in the door opening direction thereafter causing opening movement of the door.

An openable and closable door arrangement for a doorway, comprising:
- an upright sliding door positioned for generally solely horizontal movement between opened and closed positions relative to a doorway, said door being supported on a generally horizontally elongated track which extends substantially parallel to one of the horizontally-extending upper and lower edges of the door;
- an activating handle mounted on one side of the door for controlling opening and closing movement thereof, said activating handle comprising a vertically elongate activating lever which adjacent one end thereof is pivotally supported on said door for vertical swinging movement about a first substantially horizontal pivot axis which extends transverse to the door, said activating lever being angularly swingably moveable solely through a small angular extent as defined between first and second end positions, said activating lever having a significant vertical orientation when in either of said end positions or at any position therebetween;
- a locking mechanism supported on said door in the vicinity of said activating handle and including a rotary locking member rotatably supported on the door for pivoting movement about a horizontal axis which extends transverse to the door, said locking mechanism including a vertically elongate locking member supported on the door for vertical sliding movement and which is interconnected to and is vertically displaced in response to rotation of the rotary locking member, said locking bolt having an end portion which projects outwardly beyond the door for engagement with an adjacent stationary structure when the door is closed and the locking bolt is in a locking position;
- and
- a motion transfer mechanism connected between a rotary hub of said activating lever and said rotary locking member for effecting rotation of the locking member in a release direction to effect unlocking of the locking bolt in response to application of a manually-applied generally sidewardly-directed horizontally oriented opening force against said activating lever so as to effect swinging of the activating lever from one end position into the other end position to cause retraction of the locking bolt with the continued application of said opening force to said actuating lever thereafter effecting opening of the sliding door;
- whereby application of a single direction opening force and motion against the activating lever is effective for initially unlocking and thereafter effecting opening of the sliding door.

An openable and closable door arrangement for a doorway, comprising:
- an upright sliding door positioned for generally solely horizontal movement between opened and closed positions relative to a doorway;
- an activating handle mounted on one side of the door for controlling opening and closing movement thereof, said activating handle comprising an elongate activating lever which is pivotally supported on said door for vertical swinging movement about a first substantially horizontal pivot axis which extends transverse to the door, said activating lever being angularly swingably moveable through a small angular extent as defined between first and second end positions, said activating lever having a significant vertical orientation when in either of said end positions or at any position therebetween;
- a locking mechanism supported on said door in the vicinity of said activating handle and including a vertically elongate locking bolt supported on the door for vertical sliding movement, said locking bolt having an end portion which projects outwardly beyond the door for engagement with an adjacent stationary structure when the door is closed and the locking bolt is in a locking position;
- and
- a motion transfer mechanism connected between said activating lever and said locking mechanism to effect unlocking of the locking bolt in response to application of a manually-applied generally sidewardly-directed horizontally oriented opening force against said activating handle so as to effect swinging of the activating handle from one end position into the other end position to cause retraction of the locking bolt with the continued application of said opening force to said actuating handle thereafter effecting opening of the sliding door;
- whereby application of a single direction opening force and motion against the activating handle is effective for initially unlocking and thereafter effecting opening of the sliding door.

An openable and closable door arrangement for a doorway, comprising:
- an upright sliding door positioned for generally solely horizontal and rectilinear movement between opened and closed positions relative to a doorway, the door defining inside and outside surfaces on opposite sides thereof;
- an activating handle mounted on the door adjacent the inside surface thereof for controlling the horizontal opening and closing movement of the door, said activating handle being movably supported on said door for movement through a small horizontal extent as defined between first and second end positions;
- a locking mechanism supported on said door in the vicinity of said activating handle and including a locking member supported on the door for movement between a retracted position and a locking position wherein an end portion of the locking member projects outwardly beyond the door for engagement with an adjacent stationary structure when the door is closed;
- and
- a motion transfer mechanism connected between the activating handle and said locking member for effecting movement of the locking member in a release direction to effect unlocking of the locking member in response to application of a manually-applied generally sidewardly-directed horizontally oriented opening force against said activating handle so as to effect movement of the activating handle from one end position into the other end position to cause retraction of the locking member with the continued application of said opening force to said actuating handle thereafter effecting horizontal opening of the sliding door;
- whereby application of a single direction opening force and motion against the activating handle is effective for initially unlocking and thereafter effecting opening of the sliding door.
