Abstract
An improved adjustable display support is disclosed wherein a pair of coaxially telescopic tubes are provided with an O-ring and cap clutch assembly. The resilient O-ring clutch rests on one terminal end of the tube having the larger diameter and surrounds and grips the tube with the smaller diameter that fits there inside. Surrounding the outer, larger tube, the O-ring, and the smaller, inner tube is a cap which remains in a generally fixed relationship in regard to the outer tube. The smaller, inner tube is thus adjustable within the larger tube and the resilient O-ring keeps it in place. In this fashion, the coaxial tube may be extended to a position and remain in that position through the action of the clutch. The assembly is provided with a base support and a display carrying support.
Claims4
An improved adjustable display apparatus comprising:
- a base support, where said base support includes a base support tube section having a diameter and further including a terminal end having a generally circular cross section;
- a display support, where said display support includes a display support tube section having a diameter dimensioned and configured such that said display support tube section fits within said base support tube section to allow telescopic interengagement therebetween;
- a resilient O-ring, said O-ring dimensioned and configured such that it rests on said terminal end and when said display support tube section is fitted within said base support tube section thus allowing telescopic interengagement therebetween, said resilient O-ring firmly grips said display support tube section;
- and
- an O-ring seating means for maintaining said resilient O-ring in a substantially fixed relationship with said terminal end of said base support tube section, said seating means covering said O-ring and enclosing said terminal end, including an aperture to permit said display support to pass therethrough said O-ring seating means including a flange, wherein said resilient O-ring is located directly between said flange and said terminal end;
- whereby
- a predetermined position can be maintained through frictional interference between said resilient O-ring held by said O-ring seating means and said display support tube section when telescopic interengagement exists between said base support tube section and said display support tube section.
