Abstract
An adjustable levelling pad includes a first component provided with first screw threads, a second component provided with second screw threads cooperating with the first screw threads of the first component and a bearing element having a bearing surface cooperating with the first component. The second component has an upper surface having an inclined surface portion, the inclined surface portion being inclined in the radial outward direction at an angle relative to an axis perpendicular to the axis of elevation of the adjustable pad.
Claims18
An adjustable levelling pad comprising:
- a first component comprising a first portion and a second portion, the first portion having a first outer diameter and first screw threads and the second portion having a second outer diameter greater than the first outer diameter and a bottom surface;
- a second component having a through-opening having second screw threads cooperating with the first screw threads of the first component;
- and
- a bearing element having a bearing surface cooperating with the first component,
- wherein the second component comprises an upper surface including a first part surrounding the through-opening and a second part surrounding the first part,
- wherein the first component is shiftable between a first position in which the bottom surface of the second portion of the first component directly contacts the first part of the upper surface of the second component and a second position in which the bottom surface of the second portion of the first component is spaced from the first part of the upper surface of the second component in a direction of an axis of elevation of the adjustable levelling pad,
- wherein the second part is inclined in a radial outward direction away from the first component at an angle relative to the first part, and
- wherein the second part has an outer diameter greater than the second outer diameter of the first component.
