Abstract
A self-retracting tie down winch for tying cargo on a vehicle is provided. The self-retracting tie down winch comprise a frame that can be attached temporarily or permanently to the transport vehicle, a binding system to secure the cargo, the binding system comprising a gear and a unidirectional pawl and driver to insert a binding media. The self-retracting tie down winch further comprises a space to spool the tie down media around the winch shaft, a self-retracting mechanism for the tie down media to self-retract, and a self-retracting mechanism. The self-retracting mechanism can be stopped in a locking state at given length to ensure a tension free tie down media to facilitate its placement. It can be re-engaged from the locking state to rewind the tie down media.
Claims16
A self-retracting tie down winch for securing a cargo on a vehicle, comprising:
- a frame for mounting to the vehicle;
- a shaft rotatably mounted to the frame adapted to receive a tie down media to be used to secure the cargo, the tie down media being adapted to be wound around the shaft, and urging rotation along with the shaft when the tie down media is wound or unwound;
- a biasing means fixedly mounted to the shaft, the biasing means being anchored to the frame;
- and
- a control mechanism to operate in at least two states, comprising one state preventing the tie down media to wind, and another state allowing the tie down media to rewind freely under the load accumulated in the biasing means, comprising:
- a toothed gear comprising a first tooth-free part separating two teethed parts;
- and
- a biased pawl cooperating with the toothed gear, wherein upon unwinding the tie down media, rotation of the shaft loads the biasing means, and wherein load accumulated in the biasing means helps rewind the tie down media around the shaft, wherein the toothed gear comprising a second first tooth-free part separating the two teethed parts.
A vehicle comprising a cargo bed and a self-retracting tie down winch for securing a cargo on the cargo bed, comprising:
- a frame for mounting to the vehicle;
- a shaft rotatably mounted to the frame adapted to receive a tie down media to be used to secure the cargo, the tie down media being adapted to be wound around the shaft, and urging rotation along with the shaft when the tie down media is wound or unwound;
- a biasing means fixedly mounted to the shaft, the biasing means being anchored to the frame;
- and
- a control mechanism able to operate in at least two states, comprising one state preventing the tie down media to wind, and another state allowing the tie down media to rewind freely under the load accumulated in the biasing means, comprising:
- a toothed gear comprising a first tooth-free part separating two teethed parts;
- and
- a biased pawl cooperating with the first toothed gear;
- wherein upon unwinding the tie down media, rotation of the shaft loads the biasing means, and wherein load accumulated in the biasing means helps rewind the tie down media around the shaft, wherein the toothed gear comprising a second first tooth-free part separating the two teethed parts.
