Title:
UNALIGNED MULTIPLE-COLUMN HEIGHT ADJUSTABLE PEDESTALS FOR TABLES AND CHAIRS THAT TILT AND SLIDE
Document Type and Number:
WIPO Patent Application WO2002043526
Kind Code:
A3
Abstract:
A height adjustable pedestal having two or more height adjustable telescoping columns (18) can be raised or lowered freely without binding. The telescoping columns engage a furniture component through at least two pivots and at least one slider. Pivotal and sliding engagement of the furniture component with the telescoping columns allows the furniture component to slide and pivot freely over the column precluding axial misalignment of the telescoping members of the columns due to non-parallellity between columns, or misalignment caused by columns moving at disparate speeds. Engagement of the furniture component in this manner also allows the telescoping columns to be adjusted independently of one another providing, for example, a tiltable table top or chair seat. Further, the table top or chair seat can slide in relationship to the height adjustable telescoping columns.
