Abstract
A hinged chair having a seat, a fold-don back and a base that is detachable from the bottom of the seat to enable the chair to be shipped disassembled, in a compact container. The fold-down back is hingedly coupled to the seat by pivots that extend through frame posts at opposite sides of the back. To reduce the profile of the chair, the fold-down back is rotatable at the pivots between a vertical position standing upwardly from the seat and a horizontal position lying over and in opposite facing alignment with the seat. With the chair removed from its shipping container and the chair back rotated to its vertical upstanding position, locking pins are pushed through the frame posts of the back above the pivots to lock the back in the vertical position ready for use.
Claims19
A chair to sit on the ground and comprising:
- a seat having first and second upturned frame posts extending therefrom;
- a base connected to the seat to hold the seat above the ground;
- a back having first and second back posts extending therefrom;
- first and second pivots;
- and
- first and second hinge enclosures, one of said hinge enclosures being fixedly connected to and standing upwardly from one of the first and second upturned frame posts of said seat to surround one of the first and second back posts of said back, the one of said first and second hinge enclosures having a pivot receiving slot formed therein;
- and
- one of said first and second pivots extending through the pivot receiving slot formed in the one of said first and second hinge enclosures and the one of the first and second back posts surrounded by said one hinge enclosure such that said back is hingedly coupled to and rotatable relative to said seat between an upstanding position extending upwardly from said seat and a folded position lying over and in opposite facing alignment with said seat,
- wherein the one of the first and second back posts of said back is slidable upwardly and downwardly through the one of said first and second hinge enclosures and the one of said first and second pivots is correspondingly slidable upwardly and downwardly through the pivot receiving slot formed in said one hinge enclosure, said back rotating from said upstanding position to said folded position when the one of the first and second back posts slides upwardly through the one of said first and second hinge enclosures and the one of said first and second pivots slides upwardly through said pivot receiving slot.

A chair comprising:
- a seat having at least one back supporting post extending upwardly therefrom;
- a back having at least one back coupling post extending downwardly therefrom;
- at least one pivot;
- and
- a hinge enclosure fixedly connected to and standing upwardly from the back supporting post of said seat to surround the back coupling post of said back, said hinge enclosure having a pivot receiving slot formed therein, and said pivot extending through said pivot receiving slot and said back coupling post surrounded by said hinge enclosure such that said back is hingedly coupled to and rotatable relative to said seat between an upstanding position extending upwardly from said seat and a folded position lying over and in opposite facing alignment with said seat,
- wherein the back coupling post of said back is slidable upwardly and downwardly through said hinge enclosure and said pivot is correspondingly slidable upwardly and downwardly through the pivot receiving slot formed in said hinge enclosure, said back rotating from said upstanding position to said folded position when said back coupling post slides upwardly through said hinge enclosure and said pivot slides upwardly through said pivot receiving slot.
