Benefits of technology

[0008] The sleeve sections of the column move relative to one another by guide rails and cam followers located on opposing sides of the column sleeve sections. The guide rails are longitudinally extending with a pair of oppositely disposed parallel guide surfaces. The guide rails are located between the first and second sleeve sections, and the second and third sleeve sections, with accompanying cam followers for each rail. The rails are mounted on the outside and inside of the second sleeve section, and the cam followers have an eccentric diameter for adjustment against the rails. The cam followers

Example

[0021] Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structure. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.

[0022]FIG. 1 is a perspective view of an examination table 10. The table generally comprises a support bracket 12, a support column 14, and a base 16. The focus of the present invention is on the support column 14 and the adjustable nature of the column 14. The column 14 generally comprises three sleeve sections or members: a first or lower sleeve section 18, a second or middle sleeve section 20, and a third or upper sleeve section 22. The first sleeve section 18 is attached to the base 16, the second sleeve section 20 is attached to the first sleeve section 18 and the third sleeve section 22, an...

Abstract

An adjustable height support column for an examination table/chair is disclosed. The column includes nesting sleeve sections that are relatively slidable with respect to one another. The column uses camming guide rails in combination with cam followers located on the sleeve sections to provide for a column that is sturdy, compact, and may support a sufficiently heavy patient. One or more linear actuators provide for extension and retraction of the column.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to medical examination tables and, more specifically, to adjustable columns for examination tables. [0002] Adjustable tables have been previously used in the medical fields. Generally, the focus of prior table adjustment has been for angular or rotational displacement of the table bed. That is, the table base remains stationary while mechanical or hydraulic means tilt or angle the bed in other directions. Though these designs assist an examiner in repositioning a patient for different procedures, they do not allow for vertical mobility of the table. For instance, if a patient were to be moved from a wheelchair or a low resting gurney, such table would still need the patient to be lifted onto the table. [0003] Previous inventions have contemplated adjustable bases. For instance, Schnelle et al. (U.S. Pat. No. 4,589,642), discloses an adjustable base that uses hydraulic cylinders moving in opposite directions to adjust t...
