ABSTRACT:
FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION
Folding aluminum beach chairs are favored by attendees at sporting events and by beach goers due to their light weight. Nevertheless, such beach chairs are bulky and in instances where it is either desirable or necessary to carry a number of items to the beach, such as beach chairs, beach umbrellas, beach towels, picnic items and the like, these items can be awkward, clumsy and heavy to carry and manipulate.
BRIEF DESCRIPTION OF THE INVENTION
The present invention is characterized by comprising a kit provided with wheeled assemblies for simply and easily converting a folding aluminum beach chair into a wheeled tote capable of carrying bulky and clumsy beach items to the beach or to other events using bungee cords to hold down the items being toted.
The beach chair is a conventional beach chair formed of aluminum tubing sections pivotally connected to one another to define a seat portion, back portion and a pair of substantially U-shaped leg portions and preferably, arm portions. Fabric or plastic webs are arranged across the seat and back portions to form surfaces for supporting the body and back of a user.
The wheeled assemblies are clampingly mounted to the rear leg portion of the beach chair so as to be retained on the arms of the U-shaped portion while being slidable therealong.
An extension is also clamped to each bracket assembly, the extensions of each having an opening for receiving an axle. A pair of wheels are provided on each axle on opposite sides of the extension and locking end caps are snap-fitted thereto.
The wheels are positioned along the rear side of the beach chair so that they do not touch the supporting surface upon which the chair is positioned while assuring that only the wheels engage the ground when the beach chair is folded to the collapsed position and tilted rearwardly, enabling the beach chair to be wheeled from place to place or, in addition thereto, enabling the collapsed beach chair to serve as a wheeled tote to carry items to the beach or elsewhere by laying these items upon the supporting webs and holding the items down with bungee cords.
In order to be assured that the wheels are arranged in the proper position, the brackets which are slidably mounted to the rear leg portion of the beach chair are, after being properly positioned, secured in the desired position by self-tapping screws extending through openings in the brackets and being secured to the tubular leg. Similar self-tapping screws are provided to maintain the aforesaid extension at the proper position after the extensions are moved to the desired location projecting from the bracket assemblies.
The bracket assemblies are light in weight and do not interfere with the normal use of the beach chair in either the upright or collapsed positions.
OBJECTS OF THE INVENTION
It is therefore one object of the present invention to provide a novel assembly for converting a foldable beach chair into a wheeled tote.
Still another object of the present invention is to provide a novel wheel assembly for mounting to a foldable beach chair and which is capable of placing the wheels upon the beach chair so that they do not interfere with the normal use of the beach chair and are active when the beach chair is folded and tilted rearwardly enabling the beach chair to be used as a wheeled tote or for purposes of wheeling the beach chair from one location to another.
