ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field Of The Invention
This invention relates to foldable chairs, in general, and to a collapsible chair especially useful at a beach or seashore location, in particular.
2. Description Of The Related Art
Folding or collapsible chairs in the nature of furniture have been described in such U.S. Pat. Nos. 3,635,520 (Roher et al) and 5,984,406 (Lee). In a multiple seat arrangement, they are also described in U.S. Pat. No. 5,570,928 (Staunton et al). For outdoor use, in camping and watching sports games, chairs of this type have been illustrated in U.S. Pat. No. 5,893,605 (Chang). When a reclining chair is desired for camping, hiking, fishing, and concert events, a construction of the type shown in U.S. Pat. No. 5,882,068 (Levine) is said to be useful.
While chairs of these types may prove adequate to suit their intended purposes, they have proven deficient when employed at beaches or seashore locations where users prefer low seat heights, typically no more than 6″ to 10″ above ground. While adjustments for multiple reclining positions in these chairs are highly desirable, the need for adjusting the position safely and easily is equally as important. As the reclining chair is oftentimes left unoccupied when open, it is almost as important, if not more so, for the beach chair to have a degree of stability about it, so as to limit its propensity to be blown about by wind gusts, as well as when being sat upon by a user. These various features, however, are not readily available with the type of folding chair arrangements that typify the prior art.
SUMMARY OF THE INVENTION
As will become clear from the following description, the reclining beach chair of the invention replaces the straight leg “X” tubing which characterizes standard designs by an “X” shape tubing incorporating pairs of bends to allow for bringing the seat level of the chair closer to the ground. By replacing the oftentimes used “brake lock” (for free-hand adjustment in sliding the chair back to the desired incline position) with a “positive” slide lock in which a “snap” is secured within a capturing aperture, a true, predetermined locking position results once the recline is set. As will be further described, to increase stability, the beach chair of the invention is constructed to effectively push forward its center of gravity, as by making the rear legs of the chair longer than the front legs. Where desired, a bar can also be fixed between opposing left and right sides of the chair frame back to further stabilize the chair when extended to an open position. In accordance with the invention, both the chair and the stabilizer bar are easily collapsible into a compact package to facilitate the carrying about and storage of this recliner.
