The present invention concerns a foldable head rest which provides elevated support for a person's head while lying in the prone position at the beach or other leisure place, for example. The head rest may be easily carried in a folded flat configuration in one's luggage or hand and quickly unfolded for use at the beach. The head rest broadly comprises a pair of rectangular frames including an interior and exterior frame each having two seats of two offset but parallel leg portions. Cross members join the opposite leg portions of each frame at their otherwise free ends. Fabric panels are secured to the respective cross members of the opposite frames including a top panel which provides direct support for the head and a bottom panel which supportively contacts the sand or ground to prevent the head rest from sinking into the sand or ground. Each set of leg portions of each frame are formed at their midsections with a central hub. The adjoining hubs have a protruding hinge shaft and receiving hole on the exterior and interior frames respectively, for interlocking the frames and providing pivotal movement therebetween.

1. A foldable headrest having a first opened and second folded position comprising: (a) a first molded integral one piece rectangular frame having upper and lower parallel ends and connecting parallel side legs, (b) a second molded integral one piece rectangular frame having upper and lower parallel ends and connecting parallel side legs, (c) said first and said second frames having substantially equal length, (d) said parallel side legs of said first frame having upper, lower and central portions, (e) said parallel side legs of said second frame having upper, lower and central portions, (f) said upper and lower portions of said parallel side legs of said first frame being spaced apart from each other substantially the same distance as said upper and lower portions of said parallel side legs of said second frame are spaced from each other, (g) said central portions of said parallel legs of said first frame being spaced apart a distance greater than said upper and lower portions of said parallel legs of said first frame, (h) said central portions of said parallel legs of said second frame having at least a portion thereof being spaced apart a shorter distance than at least a portion of said upper and lower portions of said parallel legs of said second frame, (i) said central portion of each of said parallel legs of said first frame having an inwardly projecting key integrally molded therewith, (j) said central portion of each of said parallel legs of said second frame having a cooperating opening therethrough for receiving a respective cooperating key of said first frame, (k) each of said frames being resiliently flexible a distance sufficient for said respective inwardly projecting keys of said first frame to be engaged with and disengaged from said respective openings of said second frame by bowing of said first and second frames outwardly with respect to each other, (l) said upper portions of said parallel legs of said first and second frames being offset laterally from said lower portions of said parallel legs of said first and second frames, (m) each of said central portions of said legs of said first and second frames having short laterally spaced extensions and a central hub portion, (n) said laterally spaced extensions being tangentially arranged on their respective hub portions, (o) stop connecting means on each of said laterally spaced extensions of said central portion connected to their respective upper and lower leg portions for limiting the travel of said frames when in opened and closed positions, (p) a first fabric panel having ends, one end being connected to said first frame upper end and the other end connected to said second frame upper end, (q) a second fabric panel having ends, one end being connected to said first frame lower end and the other end connected to said second frame lower end, and (r) said panels being of a length so that when said frames are in said opened position, said panels will be substantially taut. 2. A foldable headrest as in claim 1, wherein: (a) said keys of said first frame include means allowing disengagement of said keys from said respective openings of said second frame only when said headrest is in said folded position and preventing disengagement at all other times. 3. A foldable headrest as in claim 2, wherein: (a) said means allowing disengagement includes key projections extending parallel to said side legs of said first frame, and (b) said openings being keyhole shaped so as to be aligned with and to receive said projections only when said headrest is in said folded position.
