Abstract
Abstract A beach chair including an integral tubular frame having a top run joined on its opposite extremities with downwardly projecting side legs which terminate at their lower extremities in stakes for being driven into the beach. A tubular headrest is telescoped onto the top run and the upper extremity of a strut projects laterally through such headrest and is rotatably connected with such top run for pivoting from a collapsed position disposed in the general plane of the side legs to a supporting position angled outwardly and rearwardly from such side legs. A web is stretched between the side legs and, if desirable, an apron or flap may project from the lower extremity thereof to serve as a cover over an underlying seating area.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
197 words
A chair for use on a beach comprising: a generally rectangular open bottom frame formed with a horizontal top run joined at its opposite extremities with oppositely disposed side legs projecting downwardly and defining at each of their lower extremities respective side stakes, said side stakes particularly characterized by an inclination of said side stakes with respect to said corresponding side legs so that when said beach chair is set up on said beach with said side legs inclined, said side stakes are generally vertical, thereby maximizing the holding power of said side stakes; a strut rotatably connected on one extremity with said top run for rotating thereabout from a collapsed position in the plane of said side legs to support position angled outwardly therefrom and defining on its bottom extremity a strut stake; web means connected on its opposite ends with said side legs to form a back rest; and, a generally tubular headrest cushion telescoped over said top run whereby said strut may be rotated to said support position and said strut stake driven into the beach so a user may rest his back against said web means and his head against said headrest cushion.
Claim 2
Dependent Claim
197 words
A chair for use on a beach comprising: a generally rectangular open bottom frame formed with a horizontal top run joined at its opposite extremities with oppositely disposed side legs projecting downwardly and defining at each of their lower extremities respective side stakes, said side stakes particularly characterized by an inclination of said side stakes with respect to said corresponding side legs so that when said beach chair is set up on said beach with said side legs inclined, said side stakes are generally vertical, thereby maximizing the holding power of said side stakes; a strut rotatably connected on one extremity with said top run for rotating thereabout from a collapsed position in the plane of said side legs to support position angled outwardly therefrom and defining on its bottom extremity a strut stake; web means connected on its opposite ends with said side legs to form a back rest; and, a generally tubular headrest cushion telescoped over said top run whereby said strut may be rotated to said support position and said strut stake driven into the beach so a user may rest his back against said web means and his head against said headrest cushion.
Claim 3
Dependent Claim
164 words
A beach chair comprising: a generally rectangular open bottom frame formed with a horizontal top run joined at its opposite extremities with oppositely disposed side legs projecting downwardly and defining at their lower extremities respective side stakes, said side legs are formed with substantially straight intermediate lengths and then bent to project said side stakes at an angle thereto; a strut rotatably connected on one extremity with said top run for rotating thereabout from a collapsed position in the plane of said side legs to support position angled outwardly therefrom and defining on its bottom extremity a strut stake; web means connected on its opposite ends with said side legs to form a backrest; and, a generally tubular headrest cushion telescoped over said top run whereby said strut may be rotated to said support position and said opposite extremities of said webbing are wrapped around said intermediate lengths to cause said side stakes to resist free telescoping of said webbing from said intermediate lengths.

Claim 5
Dependent Claim
165 words
A beach chair comprising: a generally rectangular open bottom frame formed with horizontal top run joined at its opposite extremities with oppositely disposed side legs projecting downwardly and defining at their lower extremities respective side stakes; a strut rotatably connected on one extremity with said top run for rotating thereabout from a collapsed position in the plane of said side legs to support position angled outwardly therefrom and defining on its bottom extremity, a strut stake; web means connected on its opposite ends with said side legs to form a backrest; a generally tubular headrest cushion telescoped over said top run whereby said strut may be rotated to said support position and said strut stake driven into the beach so a user may rest his back against said web means and his head against said headrest cushion; and a pair of shoulder straps connected on their respective one ends with said top run and on their respective opposite ends with the bottom of said webbing.
Claim 6
Dependent Claim
165 words
A beach chair comprising: a generally rectangular open bottom frame formed with horizontal top run joined at its opposite extremities with oppositely disposed side legs projecting downwardly and defining at their lower extremities respective side stakes; a strut rotatably connected on one extremity with said top run for rotating thereabout from a collapsed position in the plane of said side legs to support position angled outwardly therefrom and defining on its bottom extremity, a strut stake; web means connected on its opposite ends with said side legs to form a backrest; a generally tubular headrest cushion telescoped over said top run whereby said strut may be rotated to said support position and said strut stake driven into the beach so a user may rest his back against said web means and his head against said headrest cushion; and a pair of shoulder straps connected on their respective one ends with said top run and on their respective opposite ends with the bottom of said webbing.
