Tray device for attachment to a vertical pole
First Claim
1. A tray assembly for attaching to a vertical pole, comprising:
- a platform having a center point and a peripheral edge, said platform defining a slot that extends from an open end at said peripheral edge to a curved closed end at said center point;
a removable plate attached to said platform across said open end of said slot, wherein a threaded aperture extends through said removable plate;
a clamp element selectively positionable in said slot between said curved closed end and said removable plate, wherein said clamp element is movable back and forth within said slot;
a threaded shaft having a first end and a second end, said threaded shaft extending through said threaded aperture in said removable plate, wherein said first end of said threaded shaft engages said clamp element and moves said clamp element back and forth in said slot as said threaded shaft is selectively rotated in opposite directions; and
a handle disposed at the second end of said threaded shaft to facilitate the manual turning of the threaded shaft.

Abstract
A support device that attaches to a vertical pole so that objects can be supported along the length of a vertical pole. The support device includes a platform that has a midpoint and a peripheral edge. The platform defines a slot that extends from the peripheral edge to the midpoint, wherein the slot has a width at least as wide as the vertical pole onto which the platform attaches. A clamp element is selectively positionable within the slot. A bias mechanism is provided for biasing the clamp element into the slot toward the midpoint of the platform. A napkin holding mechanism is also provided. The napkin holding mechanism extends below the platform and holds napkins in a manner that enables single napkins to be readily removed as needed.

13. A napkin holding device, comprising:
-
a planar element having a peripheral edge; an attachment mechanism for attaching said planar element to a vertical pole; two lateral arms supported a predetermined distance below said planar element, wherein a space exists between said lateral arms and said planar element that is large enough to retain a stack of napkins; a lever element pivotably coupled to each of said lateral arms, wherein each said lever element has a first end and a second end and each said lever element is attached via a pivot to one of the lateral arms at a point between said first end and said second end; wherein each said lever element is heavier on one side of said pivot than on the other side and causes said first end of said lever element to be biased into the space between said planar element and said lateral arms. - View Dependent Claims (14, 15, 16, 17, 18)
