  • Plug for operatively connecting torsion springs to overhead shafts of counterbalancing systems used for garage doors and the like
    Patent number: 6502281
    Abstract: A plug for use in a counterbalancing mechanism of a cable-operated door. The plug is mounted about an overhead shaft and used for operatively connecting the overhead shaft to a torsion spring coaxially mounted thereon. The plug includes a cylindrical collar and a cylindrical flange. The cylindrical collar has opposite first and second portions. The collar is provided with a hooking slot for hooking a free end of the torsion spring therein and the torsion spring has a segment coaxially mounted about the first portion of the collar. The cylindrical flange is rigidly affixed to the second portion of the collar. The flange is used for transferring a torque between the torsion spring and the overhead shaft when the flange is securely fixed about the overhead shaft. The plug further includes a shouldering floor of a given length faced against the hooking slot and extending inside the collar, from the second portion towards the first portion thereof, between the collar and the overhead shaft.
