Self Adjusting Track Chain Adjustment Trolley
First Claim
1. A self adjusting chain adjustment trolley comprising:
- a translational assembly affixed to a chain tensioner assembly for translationally engaging a track, the assembly having a chain second end attachment point for engaging a chain second end; and
a door attachment point affixed to the chain tensioner assembly for engaging a sliding door;
wherein the chain tensioner assembly comprises a movable chain first end attachment point for engaging a chain first end and a force applicator attached thereto, such that the force applicator applies a predetermined amount of force to the movable chain first end attachment point to create a predetermined tension on the chain.
