AI Technical Summary

Benefits of technology

The present invention provides a folding lawn chair with extendable arms that can hold a tray, table, or desk. The arm extensions are slidably mounted on the arms and have a lock to hold the extensions in place. The arm extensions have protrusions to limit movement of the tray off the front, and there are easy ways to pull out the arm extensions. The chair allows the occupant to easily access the tray without assistance from anyone else.

Problems solved by technology

When the occupant wishes to carry out an activity such as eating from a plate, drinking from a glass, writing, or working on a portable computer or electronic tablet, however, the chair is of little or no help.

first embodiment

[0020]A first embodiment is shown in FIGS. 1-6, attached to a lawn chair 30. The lawn chair 30 is illustratively of a common design having a frame constructed to allow a generally planar seat part and a generally planar back part to fold from a working position in which they are generally at right angles to each other to a stored position in which the seat part and the back part are generally parallel. In the illustrative embodiment, the frame is made of aluminum tubing, although frames of steel tubing and wood, for example, are also well-known. Numerous constructions of such chairs are known.

[0021]In this embodiment, the folding chair 30 has a frame formed of a U-shaped forward leg tube 33, a U-shaped rear leg tube 39, a U-shaped seat tube 45, and a U-shaped back tube 47. The free ends of the leg tubes 33 and 39 are hinged to elongate plastic brackets 37, and intermediate portions of the back tube 47 are hinged to the back ends of the brackets 37. The seat tube 45 and back tube 47 ...

second embodiment

[0029]A second embodiment is shown in FIGS. 7-8. In this embodiment, a folding chair 130, which may be the same general type shown in FIGS. 1-6, has arm extensions 113 which are hinged at the fronts of the chair's arms 129. The arm extension 113 may be part of an extension assembly 111 including a supplemental arm 112 and the arm extension 113.

[0030]The supplemental arm 112 is illustratively a block of wood having a length and width similar to those of the chair's arm 129. The supplemental arm 112 may be held to the structural arm 129 of the chair 130 by Velcro straps, or by bolts run through holes bored through the arms 129 and supplemental arms 112 and secured by nuts, or by screws extending through the arms 129 and into the wooden arms 112. A cross-bore is provided at the forward end of the supplemental arm 112. Preferably, the supplemental arm 112 extends a short distance ahead of the structural arm 129, for reasons which will become apparent.

[0031]The arm extension 113 is chann...

Abstract

A folding chair having a frame constructed to allow a generally planar seat part and a generally planar back part to fold from a working position in which they are generally at right angles to each other to a stored position in which the seat part and the back part are generally parallel, the folding chair having arms, and arm extensions attached to the chair arms, the chair extensions being constructed to support a tray between them at a tray position at least substantially forward of the chair arms, the arm extensions being moveable to a position at which they do not extend substantially beyond the chair arms.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is related to and claims the benefit of U.S. Provisional Application 62 / 409,488, filed Oct. 18, 2016 and U.S. Provisional Application 62 / 275473, filed Jan. 6, 2016. The disclosures of both these applications are hereby incorporated herein by reference.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH[0002]Not applicable.BACKGROUND OF THE INVENTION[0003]This invention relates to folding chairs, and in particular to folding chairs that include a folding, light-weight tubular frame defining legs, a back rest area, a seat area, and arms. A seat, a back, and arm rests are attached to the tubular frame. The seat and back are frequently webs made of woven strips of material such as flexible plastic or woven fabric. Seats and backs may also be formed as slats or mesh rectangles. Such chairs are known commonly as lawn chairs or picnic chairs. It will be understood that in addition to traditional lawn chairs, similar chairs having e...
