A strap tensioner includes a frame, a bridge bar, a stopper, a winding shaft, a gear assembly, a crank and an observation hole. The frame has two sidewalls. The bridge bar is fixed between the two sidewalls. The stopper is of an L-shape and extends from one of the sidewalls. The gear assembly is mounted on the other sidewall and has a worm and a worm gear. The worm gear is axially connected to the winding shaft. The worm is provided with a drive shaft. The crank includes a stem connected to the drive shaft, an arm pivotedly connected to the stem and being capable of being either expanded along the stem or folded over the stem, and a handle on the arm. The observation hole is formed in the sidewall. The handle is blocked by the stopper when the arm is folded over the stem.

A tie-down apparatus includes a frame, a reel, a coils spring and a strap-replacing tool. The reel is supported on the frame. The coil spring includes an end connected to the frame and another end connected to the reel. The strap-replacing tool for gear includes a gear and a pawl. The gear is connected to the reel at an end and formed with teeth on a periphery. The is pawl engaged with the teeth of the gear so that the pawl prevents the gear from rotation in a first sense of direction and that the pawl allows the gear to spin in a second sense of direction opposite to the first sense of direction. The pawl keeps the gear in position against torque provided from the coil spring via the reel that tends to rotate the gear in the first sense of direction.

A tie-down winch is provided including a frame having a first arm and a second arm. The winch includes a shaft supported by the first arm and the second arm of the frame such that the shaft is able to rotate. The winch includes a drive socket at a first end of the shaft sized to receive a drive head of a tool to rotate the shaft.

The present invention discloses a strap system for securing a payload. The strap system includes a first fastener having a connecting crosspiece, a reversing crosspiece, and a hanger capable of attaching to the payload, and all connected together on each side by lateral members. The strap system also includes a strap attached to the connecting crosspiece of the first fastener and capable of passing around the reversing crosspiece and tightening the strap around the payload.

A tie down strap retrieval device that is configured to retrieve and roll a tie down strap after use on a flatbed style trailer. The present invention is configured to be releasably secured to a portion of the trailer. The tie down strap retrieval device includes a main support beam wherein the main support beam includes a rail engagement member that is configured to be releasably secured to a section of a trailer. The rail engagement member includes a hook member having a curved section configured to engage a rail or similar element. A roller assembly is rotatably mounted to a first side of the main support beam and includes a support plate and four mounting rods extending outward from the support plate and main support beam. A guide member is proximate the roller assembly and is configured to direct a strap onto the roller assembly.

A device for neatly winding up cargo ties includes a moveable clamp arm a first end of which projects out of an opening of the housing such that the clamp arm and the housing together form a pair of jaws that can selectively be placed about a variety of surfaces and tightened. The jaws are loosened and tightened through the rotation of a threaded rod that engages with a second end of the clamp arm at the interior of the housing causing movement of the clamp arm along a clamping axis. In some embodiments, a nut which is prevented from rotating, is disposed at the second end of the clamp arm and comprises threading that engages with the threading on the threaded rod moving the clamp arm along the clamping axis.

A device for holding a cord includes a first cord holding area shaped to receive a cord. The device further includes a hook portion interconnected with the first cord holding area, the hook portion curving from a first end of the first cord holding area, around a side of the first cord holding area to a second end of the first cord holding area, opposite the first end.

A universal device adapted to fit or be inserted within the cavity of a one directional ratchet gear to tighten tie-down straps utilized to secure cargo transported on car haulers, flatbed trailers or the like. The device includes but not limited to an elongated cylinder shape adaptor insert or hub with the ability to lock in place and having a standard, customized or dog ratchet mechanism fixed at one end thereof. A cylindrical bar socket and ratchet gear pulley extends from one side of the ratchet mechanism. The cylindrical bar socket is designed to encompass a standard, customized or dog ratchet drive shaft or opposite the elongated cylinder shape insert may encompass the aforementioned. The device herein permits the marrying of old or existing one-way ratchet gear assembly and shaft to new two-way directional or freewheel and drive without dismantling the old ratchet gear assembly; allowing old and new to rotate as one single unit.

According to an example aspect of the present invention, there is provided a spring loaded retractable device comprising a frame, a movable part hinged to a first pin and comprising an opening radially aligned to the first pin, wherein a strap is movable through the opening, and wherein the movable part is configured to move from a first position into a second position by rotating around an axis of rotation due to friction between the movable part and the moving strap.

The utility invention provides a one-way locking method using an anti-loosing strapping device for securing cargo and goods for storage and transport. It rotates a clutch cam with an operating handle and the clutch cam. The utility invention utilizes an anti-loosing strapping device, when used, the operating handle allows the free rotation of the ratchet allows the buckle to be pulled away from the ratchet to clutch cam, and the strap can be pulled out under the effect of an external force. Once the force is loosened the strap will tighten up automatically and rotate into the position where the buckle is locked by the ratchet to clutch cam. The locking method of this kind of ratchet is one-way locking, the strap can only tighten up and cannot be pulled out. Through the improvement to the structure, the combination of the strap and the ratchet mechanisms with ability to separate simultaneously, improves reliability and stability of the anti-loosing strapping device. Therefore, the invention provides better control, convenience, reliability and stability as an anti-loosing strapping device.
