Abstract:
1. A winding tool comprising: a first half hub assembly comprising a first half cylinder having a first end and a second end, a first half translational sprocket is disposed generally perpendicularly on the first half cylinder in between the first end and the second end; a second half hub assembly comprising a second half cylinder having a first end and a second end, a second half translational sprocket is disposed generally perpendicularly on the second half cylinder in between the first end and the second end, the first half hub assembly removably interlocks with the second half hub assembly via a locking means to form a generally cylindrical structure with the first half translational sprocket and second half translational sprocket being aligned, the hub assemblies together function to wrap around a garage door shaft; a first finger for removably engaging in a first finger cavity disposed on an inner surface of the first end of the first half cylinder, the first finger functions to engage a torsion spring winding cone; a second finger removably engaging in a second finger cavity disposed on an inner surface of the first end of the first half cylinder, the second finger functions to engage the torsion spring winding cone; a winding box removably attachable to the hub assemblies when the hub assemblies are interlocked, the winding box has an open top end, a middle portion, a bottom end, and an inner cavity, wherein an indentation is disposed in each a first side and a second side of the open top end of the winding box, the indentations are adapted to hold the first half cylinder and second half cylinder of the hub assemblies with the translational sprocket positioned in between the first side and second side of the winding box; a clamp assembly for securing the winding box to the hub assemblies, the clamp assembly comprises a clamp lever pivotally attached to the winding box at the top end, the clamp lever wraps over the hub assemblies and engages a locking system to temporarily secure the winding box to the hub assemblies; a worm gear disposed in the inner cavity of the winding box near the top end below the indentations, the worm gear has a first end and a second end, the worm gear is positioned such that teeth of the worm gear engage teeth of the translational sprocket when the huh assemblies are engaged in the winding box, wherein a first gear is disposed on the first end of the worm gear; a winding shaft having a first end and a second end, a second gear is disposed on the first end of the winding shaft, the second gear engages the first gear disposed on the worm gear, and a third gear is disposed on the second end of the winding shaft; and a handle bar having a first end and a second end, a fourth gear is disposed on the first end, the fourth gear engages the third gear disposed on the second end of the winding shaft and the second end of the handle bar extends out of the winding box; wherein when the handle bar is rotated the rotation of the handle bar causes the winding shaft to rotate, which causes the worm gear to rotate, which causes the translational sprocket to rotate, which causes the first half cylinder, first finger, second half cylinder, and second finger to rotate, and wherein rotation occurs in a first direction or a second direction.
