The present disclosure relates to accessories used in transportation, and in particular, relates to a strap winding apparatus for winding straps.
It is known that articles placed on a flatbed truck are secured using cargo straps, tie-down straps or other flexible members. The cargo straps are extended over the articles and the cargo straps are fastened to a deck of the flatbed truck. After use, it is preferred to organize the cargo straps for safe storage and prevent them from tangling with other objects. Typically, the cargo straps are rolled for easy storage and transportation. Rolling of the cargo straps by hand is a time-consuming task and takes considerable effort by a user or truck driver.
In order to aid the user, strap winding tools are used by the truck driver. Several strap winding tools have been proposed in the past. One such example is disclosed in a U.S. Pat. No. 7,766,271, entitled “Strap collection device for tensioning a ratchet” (“the ′271 Patent”). The ′271 Patent discloses a hand activated retainment, storage and deployment device for binding straps used to secure loads on cargo transportation vehicles such as tractor trailers. The device has a winding mechanism with a spooling reel for winding excess binding strap during use and for removable storage of the strap when not deployed.
Another example is disclosed in a PCT Publication No. 2014138777, entitled “Strap winding tool” (“the ′777 Publication”). The ′777 Publication discloses a strap winding device comprising a pair of tines extending in length from a body, and an interface extending from the body for connection to a rotating driver for rotating the tines about an axis between the tines when the strap is placed there between. In use the rotation of the tines winds the strap around the tines.
Another example is disclosed in a U.S. Pat. No. 6,824,339, entitled “Belt winch speed handle” (“the ′339 Patent”). The ′339 Patent discloses a handle for speed winding a strap back onto a belt winch having a ratchet mechanism, a winch drum and an annular cylinder is described. The speed handle generally includes an elongated arm having a grip on the upper surface adjacent the first end and a handle drum on the lower surface adjacent the second end. The handle drum includes a tapered end and is adapted to fit into the annular cylinder of a belt winch. The handler drum includes a protrusion with a tapered end, adapted to fit into an aperture on the annular cylinder. Once placed on the belt winch, the speed handle allows the user to rapidly rewind a strap back onto the winch drum.
Although the existing strap winding tools are useful, they have few problems. For example, the existing strap winding tools have a complex connection mechanism to connect to the deck of the flatbed truck. Further, they require additional tools to install and uninstall the strap winding tool from the flatbed truck.
Therefore, there is a need in the art to provide a strap winding apparatus for winding straps, the strap winding apparatus that is easy to install and uninstall from the flatbed truck.
It is an object of the present invention to provide a strap winding apparatus that avoids the drawback of known strap winding tools.
It is another object of the present invention to provide a strap winding apparatus that is easy to install and uninstall from the flatbed truck.
In order to achieve one or more objects, the present invention provides a strap winding apparatus for winding a strap. The strap winding apparatus includes a bracket and a rotating shaft assembly. The bracket includes a frame having frame holes. The bracket includes a handle member extending from the frame. The handle includes a hook member. The hook member connects to a flatbed truck and positions the frame parallel to the side of the flatbed truck. The rotating shaft assembly includes a shaft having shaft openings. The shaft openings indicate elongated slots extending along the length of the shaft and have open ends. The shaft connects to a crank having a grip. The shaft inserts through the frame holes while positioning the crank outside of the frame. The shaft openings receive the strap. The rotating shaft assembly rotates causing the strap to wind around the shaft. The shaft is removed from the frame while retaining the strap in a wounded configuration. In one example, the rotating shaft assembly is configured to position within the frame when not in use.
In one aspect of the present invention, the frame has a U-shaped member extending from the frame. Further, the frame has a support member that connects at the bottom of the handle member and the U-shaped member. The support member contacts the side of the flatbed truck. The support member, the U-shaped member and the handle member provide required strength for the frame for holding the rotating shaft assembly and to wind the strap. Further, the support member, the U-shaped member and the handle member help to position the frame at a distance from the flatbed truck and use the space between the frame and the support member for winding the strap.
In one advantageous feature of the present invention, the strap winding apparatus has a frame that is configured to receive the rotating shaft assembly when not in use. This prevents separate storage space for the rotating shaft assembly and makes it easy for storing and transporting the strap winding apparatus.
In another advantageous feature of the present invention, the handle member has a hook member that is easy to install or uninstall from the flatbed truck. In one example, the hook member has a fastener to connect the strap winding apparatus to the flatbed truck.
