Patent ID: 7913977

Claim:
A tightener, that is a device used with a variety of securing members for fastening a selected securing member around an object comprising: A tightening device tightening a securing member and temporarily connected with a jamming clamp which is in modified form of an ordinary clamp, one end of the securing member is permanently connected with said ordinary clamp and said securing member fastened around an object and its free end previously threaded through a passage between knurled elements of the ordinary clamp is pulled by hand, and said securing member exiting said ordinary clamp is automatically jammed in said ordinary clamp when pulling is stopped and said ordinary clamp after modification is further named the jamming clamp to distinguish one clamp from the other and said modification is done to enable a connection of said jamming clamp with the tightening device which comprises: a handle and built-in a ratchet mechanism in a handle's arm and said handle operating as a lever actuating the ratchet mechanism connected with a shaft turning it causing winding of the securing member onto said shaft which means a continuation pulling the securing member previously pulling by hand said securing member exiting the jamming clamp to reach a needed tension in said securing member and said securing member is automatically jammed in the jamming clamp when pulling is stopped and the handle can be used for carrying fastened object or said handle can be disconnected which means disconnecting the tightening device from the jamming clamp when the object is destined for transportation only and not for carrying; means for the tightening device for pulling the securing member exiting the jamming clamp; means for connecting the tightening-device with the jamming clamp and disconnecting from said jamming clamp; means for the jamming clamp for maintaining the securing member in tensioned state, and also for loosening it; means for the jamming clamp which allow for fast exchanging one kind of the securing member for another one means for elongating the handle for increasing the torque applied to the ratchet mechanism.
