Provided is a wheelchair fastening device, including a housing, a mounting base, a winder and an actuating mechanism. The winder and the actuating mechanism are pivotally mounted on the mounting base. The housing covers the mounting base. The actuating mechanism has a stop piece to limit the rotation of the winder, and has an actuating lever and a gear set. By operating the actuating lever, the stop piece is detached from the winder, and the gear set actuates the winder to perform the action of winding up or pulling out.

A winch for securing a load to a vehicle a is disclosed. The winch includes a mounting bracket with opposed flanges. The winch further includes a drum extending along an axis between a first end and a second end. The drum is mounted relative to the opposed flanges so that the drum is rotatable about its axis. The winch includes a gear received on the drum and a worm configured to mesh with the gear so that a rotation of the worm causes a rotation of the gear. The winch further includes a clutch assembly between the drum and the gear. The clutch assembly is biasable between a first configuration in which the gear is fixed relative to the drum about the axis of the drum and a second configuration in which the gear is rotatable relative to the drum about the axis of the drum.

A strap winding a storage device that is configured to store both a strap and a securing device, such as a ratchet, in a convenient and transportable manner.

A safety tensioning device includes a base, a handle, a winding mechanism and a first bundling strap. The first bundling strap is disposed on the main rotating shaft and the winding mechanism. The winding mechanism includes a box, a coil spring component and a winding shaft passing through the box with two ends exposed out of the box. One end of the winding shaft is attached to the coil spring component, a centrifugal self-locking mechanism to stop the winding shaft winding when a rotation speed is too fast, is attached to another end of the winding shaft.

A tie-down device configured to secure a position of an object is described that includes an extendable anchor that is extendable from a body of the tie-down device and configured to secure to a location, a spool comprising a circular plate including a first plurality of ratchet teeth along a circumference of the circular plate, a handle pivotably coupled to the body and including a second plurality of ratchet teeth, and a tab configured to be pivoted between a first position and a second position. The first position of the tab configured to allow the cog to engage with the spool such that the spool does not spin freely, and the second position of the tab configured to allow the cog to disengage from the spool such that the spool spins freely. Various embodiments of the tie-down device are described, as well as related systems, methods, and articles of manufacture.

A strap end manager holds a loose cargo strap end against a tight portion of the strap. The manage fits over an end of a loose strap, and the loose strap is wound around the manager. Top and bottom, right and left wings, fold around the strap and around the tight portion, and secure the wound loose end. The wings may include hook and loop material to retain the wings around the wound loose end. The strap end manager may further be used to facilitate storing cargo straps in the same manner as for holding loose cargo strap ends.

An apparatus for securing cargo to a flatbed of a carrier vehicle. The apparatus includes two pulley blocks, the first pulley block and the second pulley block. The first pulley block having a proximal end and a distal end, the distal end having two pulleys arranged side-by-side. The second pulley block having a proximal end and a distal end, the distal end of the second pulley having two pulleys arranged side-by-side. A first strap having a first end coupled to a first hook and the second end is coupled to a proximal end of the first pulley block. A second strap having a second hook at one end and the other end can be inserted into the second block pulley through its proximal end. The free end loops around the pulleys of the two pulley blocks and exits from the first pulley block. The free end of the second strap is having a handle.

A cargo strap rolling assembly for wrapping a cargo strap into a roll for storage includes a grip that includes a handle, a guide and a shaft. A first disk is slidable onto the shaft and a peg is coupled to the first disk. An end of the cargo strap can be wrapped around the peg when the cargo strap is passed through the guide. A second disk engages the peg such that the first disk is rotatably coupled to the second disk. A barrel is slidable onto the shaft and the barrel releasably engages the second disk such that the barrel is rotatably coupled to the second disk. A crank is removably attachable to the barrel for rotating the barrel around the shaft. In this way the cargo strap is wrapped around the barrel to form a roll for storage.

This disclosure describes a high speed winch rewind adapter for quickly rewinding a loading strap. In one implementation, the adapter includes a body having a volume sized to at least partially surround an annular end of the winch. The annular end is coupled with a ratchet mechanism of the winch and having at least one hole for receiving a winch bar. A drive connector is positioned both within the volume of the body and external to the volume of the body, the drive connector external to the volume of the body having an external profile to receive a torque, and the drive connector within the volume of the body insertable into the annular end of the winch for alignment to the axis of rotation. A coupling mechanism synchronizes the drive connector to the annular end such that both the drive connector and the annular end rotate simultaneously.

The frame of a heavy duty ratchet supports a spool about an axis of rotation. A handle, pivotable about the axis of rotation, includes protrusions engageable with toothed wheels on opposed sides of the spool to urge incremental rotation of the spool upon repetitive pivotal movement of the handle. A pair of spring-loaded pawls engage the toothed wheels to limit the direction of rotation of the toothed wheels. A cam, formed as part of the handle, disengages the pair of pawls from the toothed wheels upon pivotal movement of the handle to a certain extent to permit rotation of the spool in either direction.
