Abstract
A torsion spring torque assembly for applying torque to a torsion spring of a garage door system. The assembly comprises a separable housing, an adjustable support member, a gear assembly and a cooperating and movable coupling shaft assembly having a driven gear and a hub to engage the winding cone of a garage door torsion spring. The gear assembly has a driver gear which engages the driven gear of the coupling shaft to wind a garage door torsion spring. The driver gear of the gearbox assembly may be operated by means of a screw gun and is constructed to provide bi-directional rotation for winding and unwinding a garage door torsion spring.
Claims20
A torsion spring torque assembly comprising:
- a) a gearbox assembly having a separable housing structure having an adjustable plate connected thereto for positioning against the inside of a garage door structure to apply torque to a torsion spring hub;
- b) a gear assembly supported by said housing structure, said gear assembly having a ratchet gear with a pawl for one directional rotation, a driver gear, means to drive said driver gear and at least one reducing gear;
- and
- e) a driven gear assembly communicating with said gear assembly, said driven gear assembly having a separable hub structure for coupling to the winding cone of a torsion spring.
A torsion spring torque assembly comprising:
- a) a separable housing enclosure having a generally flat rear portion;
- b) an elongated support member adjustably mounted to said generally flat rear portion of said separable housing enclosure;
- c) a gear assembly arrangement having a pawl for one directional rotation, a driver gear and at least one reducing gear, said gear assembly positioned in said separable housing;
- and
- d) a driven gear assembly communicating with said gear assembly arrangement, said driven gear assembly having a separable hub structure for coupling to the winding cone of a shaft having a torsion spring.
