Abstract: An anti-theft device for use particularly on large vehicles such as trailers, Recreational Vehicles (RV's), and movable tiny houses that require extended storage when not in use. The main body of the device is comprised of a substantially right angled triangle-shaped structure constructed of a heavy metal plate having a broad middle portion and a pair of identical L-shaped pivotally mounted metal plates forming the feet on either side of the broad middle portion of the device. A pair of reinforcement metal bars are welded to the top and bottom of the main body of the device to provide lateral re-enforcement of the main body to hold the weight of a heavy vehicle in storage. The vehicle is lifted up with a jack, the wheels removed and the device is secured to the axle of the vehicle and effectively holds up the vehicle after the jack is removed.
Abstract: A hubstand comprised of a body (1), feet (2) (3) and reinforcement bars (4) (5) with rubber pads under the feet for increased grip on paved surfaces, such that the user lifts up the vehicle or trailer using a jack, removes the wheel/tire assembly and bolts on the hubstand in its place.
