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.

1. 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; andwherein 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, wherein each of the walls of the frame includes a flange extending outwardly from an external side, wherein each of the cams of the lever includes a second hole for receiving the flange. 2. The ratchet tie-down as claimed in claim 1 wherein each wall of the frame includes an arched edge and a first hole, with the arched edge defining first and second arched edge sections being adjacent to one another, and with the second arched edge section has a longer radius with respect to a center of the first hole than the first arched edge section, wherein the second pawl is movable from the first arched edge section to the second arched edge section, and wherein one end of the reeling device inserts through the hole. 3. The ratchet tie-down as claimed in claim 1 wherein the second hole delimits a perimeter corresponding to a perimeter of the flange and has a size marginally larger than a size of the flange in order for the flange to insert through the second hole. 4. The ratchet tie-down as claimed in claim 1 wherein each reinforcement member is in the shape of a tube with two openings. 5. The ratchet tie-down as claimed in claim 4 wherein each reinforcement member includes a cap section closing one of its openings. 6. The ratchet tie-down as claimed in claim 1 wherein each cam of the lever includes a cam section selectively urging the first pawl, and with the cam section delimits an eccentric perimeter with respect to a center of the second hole. 7. The ratchet tie-down as claimed in claim 1 including an elastic element formed with a loop and two legs extending from the loop, wherein each cam of the lever includes a slot and a boss, wherein the second pawl includes an aperture defined therein, and wherein the elastic element is provided between the cam and second pawl is provided around the boss, and leg one of the lees is rested on the cam while the other leg is rested on the second pawl. 8. The ratchet tie-down as claimed in claim 1 wherein each reinforcement member includes a ridge extending radially and annually around a peripheral edge thereof, and with the ridge defines an annular surface in contact with one lateral side of one lateral side of one ratchet wheel.
