Abstract
The invention relates to a jack with supporting parts, which are provided as profiles that have U-shaped cross-sections and lateral profile limbs ( ) or which are provided as elements with laterally elevated sheet metal lobes ( ). Said supporting parts are pivotally interconnected by joints ( ) in such a manner that the lateral profile limbs ( ) and/or the elevated sheet metal lobes ( ) overlap in the vicinity of the joints ( ), and arbors pass through borings in the lateral profile limbs ( ) or elevated sheet metal lobes ( ). The aim of the invention is to reduce the weight of a jack of the aforementioned type as well as the risk of the profile limb ( ) kinking. To this end, the bottom of the U-shaped profile or element which, with the profile limbs ( ) or sheet metal lobes ( ) thereof, tightly surrounds the other profile or element, is provided with beads ( ) or lobes ( ), which inwardly project and which are arranged inside, however, near the profile limbs ( ) or sheet metal lobes of the other profile or element.
