Folding chairs are typically used in leisure and recreational settings, for example, on a beach, on a deck, near a pool, at a game, or in a backyard. These types of chairs can be unfolded into a deployed configuration for use and folded into a folded configuration for compact storage and transportation. Despite the ability to fold a folding chair to a smaller profile, it is difficult for a user to carry multiple folded chairs together at the same time. Often, the folded chairs are difficult to grip and may unfold while being carried, potentially causing the user to drop the chairs. A user may therefore consider transporting multiple chairs in a wagon or a similar vehicle that can be pulled. However, such vehicles are bulky, difficult to maneuver in sand, and potentially expensive.
Some folding chairs can include straps that allow the folding chairs to be supported against the user's back when carried in a folded configuration. However, such straps only apply to a single folded chair, and do not facilitate connection or securement of additional chairs. It would be difficult or impossible for the user secure the straps of each individual chair to themselves in an effective manner for carrying multiple folded chairs together at the same time. Some folding chairs can include components that facilitate transport or storage of a folding chair and other items. However, these components are typically separate accessory attachment devices, for example, brackets, adapters, or the like, that are not integrated within the folding chair itself. It is difficult and expensive to acquire and assemble such attachment devices, which typically only facilitate attachment of various accessories and do not facilitate attachment of additional folding chairs. These attachment devices are not permanently attached to the folding chair and may be easily lost. These attachment devices further lack a means remaining connected to the folding chair for convenience without obstructing or otherwise interfering with a regular use of the folding chair.
Hence, there is a long-felt need for a stackable, connectable folding chair that provides a means for conveniently maintaining the chair in the folded configuration, and allowing multiple chairs to be secured to each other in the folded configuration for transport.
This summary is provided to introduce a selection of concepts in a simplified form that are further disclosed in the detailed description of the invention. This summary is not intended to determine the scope of the claimed subject matter.
In accordance with embodiments of the present disclosure, an exemplary folding chair is provided that includes holders that facilitate connection and stacking of multiple folding chairs to one another when the folding chairs are in a folded configuration. The holders allow multiple chairs to be easily carried by a user in the folded configuration, when supported using one or more straps attached to the folding chair. The apparatus/folding chair disclosed herein therefore addresses the above-recited need. The holders are integrated with the stackable, connectable folding chair to prevent loss of the holders and to allow for convenient access/use of the holders during folding and stacking of multiple chairs relative to each other. The position of the holders along the frame of the chair ensure that the holders do not obstruct or otherwise interfere with a regular use of the folding chair.
