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.

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.

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.
Abstract translation: 本公开提出了一种用于平衡卷起门的装置和方法。 第一螺纹轴同心地设置在扭转轴周围，弹簧也围绕扭转轴设置。 弹簧具有第一端和第二端。 弹簧的第一端固定到螺纹安装到螺纹轴上的第一锚板上。 弹簧的第二端相对于扭转轴固定。 当螺纹轴旋转时，第一锚板沿着螺纹轴移动，从而将弹簧纵向拉伸预定距离。 第一止动件防止第一锚板沿着螺纹轴移动超过预定位置，使得螺纹轴的进一步旋转使弹簧起伏，从而在扭转轴上施加预定的平衡转矩。

Abstract: A power tool for applying a rotational force to a spring of a door counterbalancing mechanism. The power tool has a rotatable drive member mounted on a casing carrying a power transmitting structure. The drive member has a slot with an open end for accommodating the shaft of the counterbalancing mechanism. A releasable coupling structure drivably connects the drive member with the collar attached to the spring so that rotation of the drive member will apply rotational force to the spring. A motor connected to the power transmitting structure is operable to rotate the drive member. A socket adapter or pipe adapter can be connected to the drive member so that the power tool is usable to rotate nuts, bolts and pipes.
