an adjustable pedestal adapted to support panel members of an elevated floor structure and a slope adjustable head for the same

摘要

The present invention relates to a tilt adjustable stand and adjustable head rest for supporting the panel member of the elevated floor. The pedestal 10 is provided with an annular element (20, 30) of the base block 12 and a series of interconnected screw thread is formed, the interconnect threaded annular element formed are a screw jack type to be rotatable relative to each other adjust the height of the top of the pedestal. Tilt compensation device is located in the upper portion of the stand, the tilt adjusting plate 100 and provided with a head member (50). The head member 50 is provided with a concave surface having a predetermined curvature radius. Inclination adjustment plate 100 is provided with a convex surface that has the same radius of curvature, it is placed on top of said head member. The pedestal 10 is configured to be adjusted typically from zero to five percent adjusted to increase by one percent. The upper member is provided with a series of holes 72 configured in a spiral around one central hole (56) and said center hole. The adjusting member is provided with a dependent pegs (132, 134) in mutually opposite positions with two radially and dependent central cylindrical member 110, the cylindrical member is located within the central hole 56, and the subordinate pegs are spaced apart in each space on the side of a central cylindrical member located in the hole of the upper member. It is the angle of the inclination adjustment plate about the vertical axis changes as its center the tilt around the curvature adjustment plate 100 is rotated thereby to compensate for the surface tilt of the stand is positioned. ; Tilt adjusting head panel height, recesses, projections, adjusting member
