Device and Method for Stabilizing a Chair on Unstable Surfaces

Abstract

The present invention is a device and method for stabilizing a chair on unstable ground. The device is particularly suited for chairs having horizontal or longitudinal leg support sections that contact the ground. The device comprises an elongated platform body having a longitudinal axis along its length and a horizontal axis along its width. The platform body has an upper surface, a ground contacting surface and a perimeter edge. The upper surface comprises at least one adapter positioned along the longitudinal axis for affixing the device to the horizontal or longitudinal leg support section of a chair. The increased surface area provided by the device reduces or eliminates instability when the chair is used on unstable surfaces such as sand, snow, gravel or grass.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to a device that can be affixed to the horizontal or longitudinal leg supports of a chair to reduce or prevent the chair from shifting or sinking on unstable ground. More specifically, the device distributes the weight of the user over a larger surface area reducing or preventing the chair legs from sink in sand, gravel, snow or grass.[0003]2. Prior Art[0004]Folding chairs are easily transported because of their compact size and are a popular device for use with outside activities such as camping, sun bathing and picnics. There are several different types of folding chairs that are frequently used including the beach folding chair, which is generally lower to the ground than a regular sized folding chair, the standard height folding chair and the lounge chair or chaise lounge. Their popularity is derived from a compact and lightweight construction and relatively low cost.[0005]The material and str...

AI Technical Summary

Benefits of technology

The present invention is an adapter that can be attached to the legs of a chair to make it more stable on unstable ground such as sand, snow, gravel, or grass. It increases the surface area of the chair, reducing or eliminating instability. This also allows for a more stable and comfortable use of the chair. The method involves attaching the stabilizer to the chair's legs and using it to make the chair more stable.

Problems solved by technology

However, when placed on an unstable surface such as sand or snow they have a tendency to sink.

To a lesser degree the stability of the chair is also affected when placed on surfaces such as gravel and grass.

Increasing weight generally increases the instability of these chairs on unstable surfaces.

The effect of sinking in sand or snow and the side to side instability that can occur on grass or gravel applies forces at angles the structure was not intended or designed to support.

Depending on the amount of weight applied under these conditions there can be a catastrophic failure of the structural integrity resulting in the chair collapsing and potential injury to the user.

While these adapters help to stabilize the folding chair from side to side motion they do not provide sufficient surface area to reduce or prevent sinking of the legs on unstable surfaces such as sand.
