Patent ID: 6889946

Claim:
A leveling shoe comprising: a base plate having a base surface; a support plate for supporting an object, said support plate being adjustable in a height direction perpendicular to the base surface; an adjusting wedge device for adjusting the height of said support plate, said adjusting wedge device including an adjusting wedge and a counterwedge, said adjusting wedge resting on said base plate and defining a supporting surface for supporting the support plate, said counterwedge resting on said base plate and defining a supporting surface for supporting the support plate; and a screw spindle for displacing said adjusting wedge and said counterwedge reciprocally towards and away from each other in a direction that is transverse to the elevation, said screw spindle comprising first and second threaded portions displaying the same thread pitch, but opposite thread direction, such that the supporting surfaces of said adjusting wedge and said counterwedge, in every position, are arranged symmetrically with respect to a first plane (E,) that is perpendicular to the base surface, and in which the axis of the connecting bolt runs, and to which the screw spindle axis is positioned at a right angle, wherein said support plate includes an opening through which a connecting bolt can project essentially at a right angle relative to the base surface so that the object can be screwed with the base plate or with a fundament by means of the connecting bolt, and wherein the first threaded portion of said screw spindle engages with in a threaded bore hole in said adjusting wedge and the second threaded portion of said screw spindle engages in a threaded bore hole of a plate, which is arranged on the other side of said adjusting wedge relative to said counterwedge, wherein said plate is permanently fixed to the counterwedge.
