Wheel-locking device to secure vehicles on the cargo platform of transport vehicles

An improved wheel-locking device for securing vehicles on the movable cargo platform of transport vehicles, comprising a stop member arranged to be raised from said movable platform for engagement with one of the wheels of said vehicle, a bow intended to be applied over said vehicle wheel, a shoulder supporting said stop member in the raised position of the latter and preventing further pivoting of said stop member, a telescopically extensible arm at the outer end of which said bow is pivotally mounted, said telescopically extensible arm comprising a controllable blocking mechanism arranged to prevent extension of said telescopic arm beyond a pre-determined, set vertical position but at the same time to allow retraction of said arm, said bow, in its applied position over the tyre of said vehicle wheel, resting on said wheel and supporting said arm in its set vertical position, as a consequence of the weight of the movable part of said arm and its own weight, the improvement comprising

• said telescopic arm being pivotally mounted at its lower point of attachment and being so directed that said arm, in its raised position for the puprose of application of said bow over said vehicle wheel, forms an acute angle to a vertical plane extending at right angles to the arm pivot axis through said point of attachment of said arm and is positioned on the opposite side of said vertical plane relative to the plane formed by said raised stop member, whereby said vehicle wheel will be secured between said bow and said stop member.
