  • Patent number: 6889946
    Abstract: A leveling shoe with a base plate (1) that has a base surface (2) and with a support plate (4) for an object that can be adjusted by means of an adjusting wedge device (3) in rectangular height direction relative to the base surface (2). The leveling shoe has an improved stability and is yet simple and inexpensive in its production. The adjusting wedge device (3) includes two wedges (7,10) that can be moved towards or away from each other by actuating a screw spindle (6). The wedges are provided with support surfaces (11,12) for the support of the plate (4). The support surfaces (11,12), in every position of the wedges (7,10), are disposed symmetrically with respect to a first plane (E1) that is perpendicular to the base surface. The screw spindle axis (6) is provided with two screw parts (6a, 6b) that have identical thread pitches but opposite thread directions.

    Abstract: The invention relates to a leveling shoe with a base plate (1) that has a base surface (2) and with a support plate (4) for an object that can be adjusted by means of an adjusting wedge device (3) in a rectangular height direction to the base surface (2aim of the invention is to provide a leveling shoe that has an improved stability and is yet simple and inexpensive in its production. To this end, the adjusting wedge device (3) comprises two wedges (7, 10) that can be moved towards or away from each other by actuating a screw spindle (6), said wedges being provided with support surfaces (11, 12) for the support plate (4). Said support surfaces (11, 12), in every position of wedges (7, 10), are disposed symmetrically to a first plane (E1) that is perpendicular to the base surface and in which the axis of a fastening screw extends that links the object with the base plate (1) or with the foundation and that projects through the support plate (4). The Screw spindle axis (6) is provided with two screw parts (6a.
