View page
US Patent:
6408925, Jun 25, 2002
Filed:
Jul 27, 1999
Appl. No.:
09/361770
Inventors:
Edward Dorma - Sarasota FL
Assignee:
Industrial Door Company, Inc. - Coon Rapids MN
International Classification:
E05F 1500
US Classification:
160191, 160201, 49200
Abstract:
A method and apparatus for counterbalancing a roll-up door uses a conventional coil spring having adjacent coils engaging each other. The spring is elongated to provide for spring growth during the winding of the spring. A worm gear box operates to wind the elongated spring and retain the spring in the wound position to continuously apply torsion force to a shaft operatively connected to the door the counterbalance the door.

US Patent:
6615897, Sep 9, 2003
Filed:
Jun 10, 2002
Appl. No.:
10/166526
Inventors:
Edward Dorma - Sarasota FL
Assignee:
Industrial Door Company, Inc. - Coon Rapids MN
International Classification:
E05F 1100
US Classification:
160191, 160318, 2423751, 185 37, 267155, 16197
Abstract:
An apparatus for winding a spring on a shaft, such as for counterbalancing a roll-up door, includes a housing that carries a transmission which is positionable over the shaft. The transmission is configured to be coupled via a connector to one end of the spring, while the other end of the spring is fixed to the shaft. Rotation of the transmission results in a turning of the connector and a winding and/or elongation of the spring.

Roll-Up Door Counterbalancing Apparatus And Method

View page
US Patent:
63277441, Dec 11, 2001
Filed:
Jul 30, 1999
Appl. No.:
9/364721
Inventors:
Edward Dorma - Sarasota FL
Assignee:
Industrial Door Co., Inc. - Minneapolis MN
International Classification:
E05F 100
US Classification:
16197
Abstract:
The disclosure sets forth an apparatus and method for counterbalancing a roll-up door. A first threaded shaft is concentrically disposed around a torsion shaft and a spring is also disposed around the torsion shaft. The spring has a first end and a second end. The first end of the spring is secured to a first anchor plate that is threadably mounted to thread onto the threaded shaft. The second end of the spring is fixed relative to the torsion shaft. When the threaded shaft is rotated, the first anchor plate moves along the threaded shaft, thereby longitudinally stretching the spring a predetermined distance. A first stop prevents the movement of the first anchor plate along the threaded shaft beyond a predetermined position so that further rotation of the threaded shaft winds the spring thereby applying a predetermined counterbalancing torque on the torsion shaft.
