Abstract
A collapsible chair includes a pair of intercrossing frames pivotally interconnected at front and rear pivot points. A pair of curved back support rods extend upwardly from the frames. A back rest is secured on and between the curved back support rods and a seat extends perpendicularly from the bottom of the back rest when the chair is in the upright condition. Each of the back support rods is rotatably secured to the intercrossing frames so that the back support rods can be positioned side-by-side when the chair is in the folded condition.
Claims11
A collapsible chair for supporting a person in a sitting position comprising:
- a pair of transversely intercrossing rectangular frames pivotally interconnected at front and rear pivot points, each of said frames including upper and lower elongated horizontal members and front and rear tubular members, said frames being capable of pivotal movement about said front and rear pivot points along a common axis to move from an upright position in which said upper members are laterally spaced apart, to a folded position in which said upper members are substantially side-by-side;
- a flexible seat secured on and between said upper elongated members of said frames, said seat being substantially extended when said chair is in said upright position;
- a pair of curved back support rods extending upwardly from said rear tubular members and being rotatable relative thereto about a point located below said upper elongated horizontal members so that said back support rods can be placed substantially side-by-side when said chair is in said folded position, and
- a back rest secured on and between said back support rods above said upper elongated horizontal members.
A collapsible chair for supporting a person in a sitting position comprising:
- a pair of transversely intercrossing rectangular frames pivotally interconnected at front and rear pivot points, each of said frames including upper and lower elongated horizontal members and front and rear diagonally extending straight tubular members, said frames being capable of pivotal movement about said front and rear pivot points along a common axis to move from an upright position in which said upper members are laterally spaced apart, to a folded position in which said upper members are substantially side-by-side;
- a flexible seat secured on and between said upper elongated members of said frames, said seat being substantially extended when said chair is in said upright position;
- a pair of back support rods, each of said back support rods having a straight first section and a curved second section, the straight first section of each of said support rods being connected to and extending in axial alignment with a corresponding one of said rear tubular members and being rotatable relative thereto about a point substantially at the interconnection between said first section and said rear tubular member so that said back support rods can be placed substantially side-by-side when said chair is in said folded position, each of said curved second sections of said support rods extending upwardly from a corresponding one of said first sections of said back support rods, and
- a back rest secured on and between said back support rods.
