Abstract
The present invention relates to a collapsible chair. The chair includes a backrest for engaging with a sitter's back. A seat extends from the backrest and is where the sitter can sit. A retractable leg support may extend from the seat and can be extended to support the sitter's legs with feet off the ground. Advantageously, the sitter's feet may be safely off the ground away from ants and sand.
Claims18
A collapsible chair including:
- a backrest for engaging with a sitter's back;
- a seat extending from the backrest and upon which the sitter can sit;
- a front spur frame pivotally mounted to the seat opposite to the backrest, the front spur frame extending outwardly from the seat to a distal end region;
- and
- a retractable leg support extending from the seat and which is movable to be extended to support the sitter's legs with feet off the ground, the leg support including a U-shaped pivoting frame pivotally mounted to the distal end region of the front spur frame, the U-shaped pivoting frame configured to extend upwardly and outwardly from a base thereof to a distal end when the leg support is extended to support the sitter's legs;
- wherein a proximal end region of the front spur frame is pivotally connected to the seat;
- wherein the distal end region of the front spur frame contacts the ground when the sitter is supported by the seat wherein the backrest is provided by a backrest frame extending from a first end to a second end, wherein the second end contacts the ground when the sitter is supported by the seat;
- and wherein the chair further comprises a rear spur frame pivotally mounted to the backrest at an intermediate position between the first and second ends, wherein a distal end region of the rear spur frame contacts the ground when the sitter is supported by the seat.

A collapsible chair including:
- a backrest frame defining a backrest for engaging with a sitter's back;
- a seat frame pivotally mounting to the backrest frame and extending therefrom, the seat frame defining a seat upon which the sitter can sit;
- a rear spur frame pivotally mounted to the backrest frame;
- a front spur frame having a proximal end pivotally mounted to the seat frame opposite to the backrest frame, the front spur frame extending outwardly from the seat frame to a distal end;
- and
- a U-shaped leg support frame having first and second free ends connected by a cross member to form a rigid structure, each of the first and second free ends of the leg support frame pivotally mounted to the distal end of the front spur frame such that the leg support frame is rotatable between a first extended position and a second retracted position;
- a sheet extending between the seat frame and the cross member of the leg support frame;
- wherein, in the first extended position, the distal end of the front spur frame contacts the ground when the sitter is supported by the seat, and the leg support frame extends upwardly from the ground and outwardly away from the seat frame such that the cross member is spaced apart from the ground, the front spur frame, and the seat frame, with the cross member holding the sheet in tension to support the sitter's legs with feet off the ground;
- and
- wherein, in the second retracted position, the distal end of the front spur frame contacts the ground when the sitter is supported by the seat, and the leg support frame extends upwardly from the ground and inwardly towards the seat frame such that the cross member is spaced apart from the ground and is adjacent to the proximal end of the front spur frame and the seat frame, with the sheet member folded so that the sitter's feet engage the ground wherein the backrest frame extends from a first end to a second end, and wherein the second end contacts the ground when the sitter is supported by the seat;
- and wherein the rear spur frame is pivotally mounted to the backrest at an intermediate position between the first and second ends, wherein a distal end region of the rear spur frame contacts the ground when the sitter is supported by the seat.
