Abstract
The present invention provides at least one anti-sway trolley assembly used in conjunction with either a single sided partition set or sandwiched between first and second partition side in a double sided partition set. The anti-sway trolley assembly comprises a floating rod affixed at a first end to a trolley. Affixed at a rod second end is a floor contact member which provides frictional resistance to lateral displacement of the door. Each anti-sway trolley assembly rides in a chain guide and is affixed to a partition hinge rod. In this manner, a floor channel is not required to achieve resistance to lateral displacement forces.
Claims20
An anti-sway trolley assembly comprising:
- a trolley for translationally engaging a chain guide mounted to a door opening, the trolley affixed to a floating rod at a first end;
- and
- a bottom assembly affixed to the floating rod at a second end;
- wherein the bottom assembly comprises a floor contact member urged against a floor and the floating rod is further affixed to a hinged sliding partition at a hinge, the urged contact member inhibiting movement of the sliding partition from normal relative to a floor.
A sliding partition apparatus comprising:
- a track and a chain guide mounted to a door opening;
- a chain pulley mounted to receive a loop of chain;
- a powered sprocket mounted remotely from the pulley;
- a hinging sliding partition slidably engaged to the track;
- a lead trolley assembly adapted for translational movement and attachment to a lead partition;
- a chain operatively connecting the powered sprocket, chain pulley and lead trolley assembly;
- and
- an anti-sway trolley assembly adapted for translational movement within the chain guide,
- wherein the anti-sway trolley assembly comprises an anti-sway trolley for translationally engaging the chain guide, the trolley being affixed to a floating rod at a floating rod first end;
- and a bottom assembly affixed to the floating rod at a floating rod second end;
- wherein the bottom assembly comprises a floor contact member urged against a floor and the floating rod is further affixed to the hinging sliding partition at a hinge;
- the urged contact member inhibiting movement of the sliding partition from normal relative to a floor.
A method for limiting translational movement of a hinging sliding partition slidably mounted to a track comprising the steps of:
- a. installing a track and a chain guide to a door opening;
- b. installing a chain pulley mounted to receive a loop of chain;
- c. installing a powered sprocket mounted remotely from the pulley;
- d. installing a lead trolley assembly adapted for translational movement and attachment to a lead partition;
- e. installing a chain operatively connecting the powered sprocket, chain pulley and lead trolley assembly;
- f. installing an anti-sway trolley assembly within the chain guide;
- and
- g. attaching the hinging sliding partition to the lead trolley assembly and anti-sway trolley assembly;
- wherein the anti-sway trolley assembly comprises an anti-sway trolley for translationally engaging the chain guide, the trolley being affixed to a floating rod at a floating rod first end;
- and a bottom assembly affixed to the floating rod at a floating rod second end;
- wherein the bottom assembly comprises a floor contact member urged against a floor and the floating rod is further affixed to the hinging sliding partition at a hinge;
- the urged contact member inhibiting movement of the sliding partition from normal relative to a floor.
