Abstract
The foldable lap tray 12! of the invention includes a flat web 11! to cover the wearer's lap, a foldable bib 13! attached to the lap tray, and a loop of spring material 10! that holds the web taut when the spring is fully extended. The bib is reversibly connected to the user's neck by a circular strap 16! or other well known means of attachment, preferably with a slidable closure element 17!. The lap tray is foldable by collapsing the spring into an odd-numbered series of smaller connected loops. In one embodiment, the lap tray has one side that is relatively concave 18! so that the tray accommodates the contour of the user's body when placed on the lap.
Claims21
A foldable lap tray, comprising:
- a flexible web of sufficient size to cover the lap of a wearer, said web defining a plane when in an opened configuration;
- elongated spring material in the form of a loop attached to a periphery of the flexible web and adapted to fold into a smaller multi-looped folded configuration upon twisting the spring material out of the plane of the web;
- and
- a foldable bib connected to the flexible web and including a means to attach the bib around the neck of a wearer.
A foldable lap tray, comprising:
- a flexible web of sufficient size to cover the lap of a wearer, said web defining a plane when in an opened configuration, said web having at its periphery first, second, third, and fourth sides and four corners;
- elongated spring material in the form of a closed loop attached to the periphery of the flexible web and adapted to fold into a smaller multi-looped folded configuration upon twisting the spring material out of the plane of the web;
- wherein in the opened configuration the first and third sides are generally parallel or are curved in a convex manner outwardly with respect to each other, the second side extends between the first and third sides, and the fourth side extends between the first and third sides and curves in a concave manner inwardly toward the second side;
- and the corners are rounded.
