ABSTRACT:
FIELD OF THE INVENTION
The present invention is generally directed to a folding chair and, more specifically, to a folding indoor/outdoor chair adapted to fold in multiple directions for easier transport and compact storage.
BACKGROUND OF THE INVENTION
The portability and ease of storage of folding chairs makes their use popular in a wide variety of applications, including use as supplemental seating for indoor and outdoor events or as portable outdoor seating in a suburban backyard, park or beach.
Folding chairs are known in the prior art that include a chair support assembly that folds in more than one direction to form a compact design. However, such known chairs include a separate flexible, unframed seat member that is removably mounted to the foldable chair support assembly. While the unframed seat member folds compactly together with the support assembly, the seat member does not provide the chair user the necessary support or comfort. Moreover, a separate backrest member is not provided only exacerbating the discomfort of the chair user.
Thus there exists a need in the art for a chair adapted to fold in at least two directions into a compact space that also provides enhanced comfort and seat and back support. There exists a further need for a folding chair adapted to fold in at least two directions into a compact space while supporting a seat member and a backrest member. There exists still a further need for a folding chair adapted to fold in at least two directions into a compact space while supporting a foldable seat member and a foldable backrest member.
SUMMARY OF THE INVENTION
In accordance with an exemplary embodiment of the present invention, a folding chair is provided comprising a seat member and backrest member mounted on a foldable chair support assembly that comprises a plurality of legs, a mounting collar having a plurality of guide openings wherein each leg of the plurality of legs extends through one of each guide hole of the plurality of guide holes and is pivotally mounted to the mounting collar to move between an open or unfolded position for supporting the chair and a folded position. The plurality of legs defining in the open position a first base for supporting the chair on a bearing surface and a second base for supporting the seat and backrest members.
In another aspect of the present invention, the seat and backrest members each include a pair of lateral support assemblies for reinforcing the seat and backrest members and stabilizing the folding chair.
In still another aspect of the present invention, the seat support assemblies each include a pivot point that together define an axis across which the seat member is folded in a first direction.
In yet another aspect of the present invention, the folding chair includes an additional pair of rear legs extending from the backrest lateral support assemblies for additional stability and support.
The above and other objects, features and advantages of the present invention will become readily apparent from the following detailed description thereof which is to be read in connection with the accompanying drawings.
