Abstract
A ratchet tie-down includes a frame, a lever including two cams pivotally connected to the frame, a reeling device rotatably mounted on the frame and lever, and a ratcheting device including two ratchet wheels mounted on the reeling device. The ratchet tie-down further includes a reinforcement assembly including two reinforcement members mounted on the reeling device. Each ratchet wheel includes two lateral sides disposed between one cam and one reinforcement member. Each reinforcement member defines an annular surface in contact with one lateral side of one ratchet wheel, and with the reinforcement member imposing an urging force in a direction perpendicular to a rotation direction of the ratchet wheel.
Claims9
A ratchet tie-down comprising:
- a frame including two walls;
- a lever including two cams pivotally connected to the two walls of the frame respectively;
- a reeling device rotatably mounted on the frame and lever;
- a ratcheting device including two ratchet wheels mounted on proximal and distal ends of the reeling device respectively and being rotatable therewith;
- a reinforcement assembly including two reinforcement members mounted on the proximal and distal ends of the reeling device respectively and being rotatable therewith;
- a first pawl movably installed on the frame and being moveable between an operative position in engagement with the ratchet wheels and an idle position away from the ratchet wheels;
- a second pawl movably installed on the lever and being moveable between an operative position in engagement with the ratchet wheels in order to rotate the reeling device and an idle position away from the ratchet wheels;
- and
- wherein each ratchet wheel includes two lateral sides disposed between one cam and one reinforcement member;
- and
- wherein each reinforcement member defines an annular surface in contact with one lateral side of one ratchet wheel, and with the reinforcement member imposing an urging force in a direction perpendicular to a rotation direction of the ratchet wheel.
