Methods and apparatus to detect and respond to drive belt failures in vertically translating doors

Abstract

Systems, apparatus, articles of manufacture, and methods to detect and respond to drive belt failures in vertically translating doors are disclosed. An example apparatus comprising: a bracket mountable adjacent to a drive belt of a vertically translating door, and a roller to be coupled to the bracket in a position to be in contact with the drive belt. The roller pivots about a first axis relative to the bracket. The roller rotates about a second axis relative to the bracket as the drive belt moves against the roller. The example apparatus further includes a sensor to sense movement of the roller about the first axis in response to a loss of tension in the drive belt.

Dependencies are inferred from the claim text.
