Flexible chair

In a chair construction having a pair of chair sides,, a seat positioned between said chair sides, a back positioned between said sides, the improvement comprising;

• each of said chair sides being formed of a single elongated flexible member;
• each of said chair sides including;
• a flexible back upright, an elongated horizontal floor rail having one end formed integral with the lower end of the back upright, a flexible front upright having its lower end formed integral with the other end of the horizontal floor rail, an arm portion formed integral with the upper end of the front upright, said arm portion being fixed to the back upright, each of said arm portions includes;
• a seat bar having one end formed integral with the upper end of the respective front upright, a back bar having one end formed integral with the other end of the seat bar, said back bar being secured to the respective back upright, an arm rest having one end formed integral with the other end of the back bar, and a lock bar having one end integrally connected to the other end of the arm rest, said lock bar being secured to the respective seat bar.

In a chair construction having a pair of chair sides, a seat positioned between said chair sides, a back positioned between said sides, the improvement comprising;

• each of said chair sides being formed of a single elongated flexible member;
• each of said chair sides including;
• a flexible back upright, an elongated horizontal floor rail having one end formed integral with the lower end of the back upright, a flexible front upright having its lower end formed integral with the other end of the horizontal floor rail, an arm portion formed integral with the upper end of the front upright, said arm portion being fixed to the back upright, each of said flexible members is tubular and has flat opposed substantially parallel faces, said faces defining planes extending across the width of the chair to allow the front and back uprights to flex and thereby allow the seat to move in a direction substantially parallel to the horizontal floor rail;
• and each arm portion including;
• a seat bar having one end formed integral with the upper end of the respective front upright, a back bar having one end formed integral with the other end of the seat bar, said back bar being secured to the respective back upright, an arm rest having one end formed integral with the other end of the back bar, and a lock bar having one end integrally connected to the other end of the arm rest, said lock bar being secured to the respective seat bar.

In a chair construction having a pair of chair sides, a seat positioned between said chair sides, a back positioned between said sides, the improvement comprising;

• each of said chair sides being formed of a single elongated flexible member;
• each of said chair sides including;
• a flexible back upright, an elongated horizontal floor rail having one end formed integral with the lower end of the back upright, a flexible front upright having its lower end formed integral with the other end of the horizontal floor rail, an arm portion formed integral with the upper end of the front upright, said arm portion being fixed to the back upright, each of said flexible members is extruded hollow polyvinyl chloride tubing having spaced flat opposed parallel faces, said opposed parallel faces of one of the chair sides being in the same plane as the respective face in the other of the chair sides, said tubing allowing the front and back uprights to flex to allow the seat to move in a substantially horizontal plane in a direction substantially parallel to the horizontal floor rails;
• and each of said arm portions including;
• a seat bar having a flat face on its uppermost surface, said seat bar having one end formed integral with the upper end of the front upright, a back bar having a cross section identical to the cross section of the respective seat bar, said back bar having one end formed integral with the other end of the respective seat bar, said back bar being secured to the respective back upright with a flat face of the back bar being in contact with a flat face of the back upright, an arm rest having a cross section identical to the cross section of the respective back bar, said arm rest having a flat face on its uppermost surface, said arm rest having one end formed integral with the other end of the respective back bar, and a lock bar having one end integrally connected to the other end of the arm rest, and said back bar having a cross section identical to the cross section of the respective arm rest, said back bar having a flat face adjacent to the flat face of the respective seat bar and being secured to the seat bar.

A chair construction comprising, in combination, a pair of chair sides, said chair sides being mirror images of each other;

• a seat positioned between said chair sides, a back positioned between said chair sides;
• each of said chair sides being formed of a single elongated flexible weather-resistant polyvinyl chloride extruded tubing;
• each of the chair sides including;
• a back upright, each back upright including;
• an upper back portion, a main back portion having its upper end formed integral with the upper back portion, and a back leg portion having its upper end formed integral with the main back portion;
• said tubing having a cross section formed by a pair of opposed parallel flat faces over a substantial portion thereof;
• an elongated horizontal floor rail having one end formed integral with the lower end of the back leg portion;
• said floor rail having one of its faces forming the lowermost portion of the chair, a front upright having its lower end formed integral with the other end of the horizontal floor rail, said front upright having one of its faces facing the respective back upright, a seat bar having one end formed integral with the upper end of the front upright, said seat bar having one of its faces facing the horizontal floor rail, a back bar having one end formed integral with the other end of the seat bar, said back bar having one of its faces adjacent to the respective back upright, a fastener securing each back bar to the respective main back portion of the back upright, an arm rest having one of its faces facing upward from the arm rest, a lock bar having one end integrally connected to the other end of the arm rest, said lock bar having one of its faces facing the respective horizontal rail, and a second fastener securing each lock bar to the respective seat bar;
• and a front cross member having opposite ends secured to the leg portions of the sides, whereby application of a force in a direction substantially parallel to the floor rails causes the front and back uprights to flex and thereby allow movement of the seat in a direction which is substantially parallel to the floor rails.
