Abstract
The present invention discloses a flexible leveling device for the leveling of various vehicles, particularly recreational vehicles. In the preferred embodiment, the flexible leveling device of the invention generally comprises an elongate member of flexible material, with first and second ends, having a series of separated elements, preferably blocks, of steadily increasing height interconnected thereto. Each of the separated elements is interconnected to the flexible member, starting at the first end thereof with the shortest element, progressing with successively longer elements to form a steady incline, and extending through the length of such member to the second end thereof. Each separated element is disposed on the flexible member so as to provide a uniform space between adjacent elements, allowing the device to be formed into a curved configuration for use, or to be folded over or rolled to facilitate storage. In use, a device of the invention is placed adjacent to each tire on the side of the vehicle to be leveled, and the vehicle is moved onto the device(s) until the desired level is achieved.
