Abstract: This disclosure presents a safe high speed roll-up door with spiral brackets. To enable a high speed operation, robust spiral brackets having efficient spacing are provided to guide the plurality of sectional slats. Durable and low noise signature rollers are used. A unique assembly configuration of the slats and the tracks guiding the rollers enable quick replacement of each individual roller without disassembling the door. A double-belt counter weight mechanism balances the door and incorporates safety sensors that prevent loosening the belts when the door is jammed. The belts are further adjustable using ratchets such that adjustment for the horizontal balance as well as weight position is made effortless. In all, the high speed roll-up door using sectional slats performs faster and quieter, withstands greater loads, and lasts longer than other existing roll-up doors with spiral brackets.

Abstract: An overhead wire tension balancer can prevent rotation of an inner cylinder connected with an overhead wire, without deteriorating rotation preventing function, even if stroke is increased, and does not complicate production steps. A rotation preventing plate is formed at the inside of an inner cylinder, and an opening which cannot rotate relative to the rotation preventing plate and which can relatively move in a condition which passes a long plate, is formed on the rotation preventing plate. The long plate is formed by two long plate pieces in an L shape in which a tip is bent, a hanging portion is formed by this bent portion and prevents the rotation preventing plate from disengaging from the long plate.
