  • Patent number: 10384591
    Abstract: A load binder with an enclosed ratchet mechanism and a removable handle consists of an elongated tubular portion, a handle, a ratcheting mechanism, a first threaded shaft, and a second threaded shaft. The first threaded shaft and the second threaded shaft are rotatably engaged to a tubular body of the elongated tubular portion. However, the first threaded shaft and the second threaded shaft do not detach from the tubular body. The tension on a chain that is attached at the first threaded shaft and the second threaded shaft can be adjusted by rotating the tubular body. The ratcheting mechanism is used to control the tubular body about the first threaded shaft and the second threaded shaft. To be protected from dirt and the like, the ratcheting mechanism is enclosed. The handle, which is removable, is used to control the ratcheting mechanism.

  • Publication number: 20140326935
    Abstract: A ratcheting load binder with enclosed ratchet mechanism has an elongated tubular body, a handle, a ratcheting mechanism, and two threaded shafts. The handle is engaged with the tubular body by the ratcheting mechanism, and is perpendicular to the tubular body. A ratchet gear and ratchet pawl of the ratcheting mechanism are enclosed within a housing of the handle. The ratchet pawl is engaged and disengaged from the ratchet gear by turning a ratchet lever outside the housing. The tubular body has internal threads at its extremities that are of opposing handedness. The threaded shafts are engaged with the internal threads within the elongated tubular body. Turning the tubular body by using the handle causes the threaded shafts to move in opposing directions, allowing a chain to be tightened or loosened between two locations by ratcheting the tubular body with the handle. The handle may also be folded for storage.
