Description
Background of the Invention
1. Field of the Invention
This invention relates to portable chairs of the picnic or beach variety which may be provided with a locking thermally insulated seat compartment for both carrying and insulating perishable foodstuffs, canned or bottled beverages, ice or the like.
2. Prior Art
Known folding chairs constructed of tubular aluminum with nylon or canvas covering material or the like are well known. These portable chairs have the virtue of being very light to carry and provide an inexpensive means for comfortable reclining. Many conventional chairs open merely to one position and are provided with legs. Some of these chairs include a seat portion and a back portion which is positioned directly on the sand or ground.
To spend the day at the beach, conventional practice involves using and carrying a comfortable chair, a portable cooler for beverages and lunches, and a container to hold towels and other small articles. This conventional practice is relatively expensive and cumbersome to carry. Known folding chairs have the disadvantage of not possessing any storage facilities which can hold small articles and thermally insulate perishable foodstuffs or bottled beverages.
A number of alternative means for constructing folding chairs have been proposed to overcome these recognized inadequacies of the conventional chairs. For example, several chairs have been devised with storage capability for beach or camping. Grebow et al U.S. Pat. No. 3,955,849 discloses such a beach chair formed of canvas with storage pockets provided on the sides of the seat for accessories.
Similarly, Menke U.S. Pat. No. 3,947,903 discloses a folding couch for beach or camping with a fabric sling arrangement for carrying and securing books and other objects.
Several arrangements have been proposed to provide a beverage or lunch container directly in a folding chair. Bramming U.S. Pat. No. 3,120,404 discloses a pair of folding seats with a container for holding vacuum bottles and sandwiches. Similarly, Davis U.S. Pat. No. 3,560,047 discloses a portable chair with a seat having therein a hollow thermally insulated container with means to introduce and dispense liquids.
Each of these alternatives has certain deficiencies. The chairs with pouches or compartments for carrying objects still require insulating means for perishable foodstuffs, fishing bait, ice or the like and are susceptible to tearing and wear as they are constructed of fabric or canvas. The portable chair in the Bramming patent still requires insulating means for foodstuffs and the glass vacuum bottles are susceptible to breakage in transport.
The alternative means proposed by Davis still require insulating and carrying means for perishable foodstuffs and the like. Additionally, this disclosure by Davis requires a wire hook securing device to a supporting plank or the like and may suffer from tipping when utilized on the beach or ground.
Summary of the Invention
It is an object of this present invention to provide an adjustable foldable chair of the type as mentioned which overcomes at least some of the aforementioned disadvantages and concurrently therewith provides a thermally insulated storage facility for securing and storing canned or bottled beverages, ice, perishable foodstuffs, fishing bait, or other small objects.
It will be seen that the present invention overcomes some of these inadequacies by providing a hingedly secured locking access panel, lid, or similar means, to a thermally insulated compartment secured to or incorporated within a lightweight seat and easily accessible to the occupant of the seat.
One object of the present invention is to provide a new and improved device of the foregoing character which opens to provide a durable comfortable seat elevating the occupant from the ground or sand at the beach, picnics, fishing, or other similar activities.
A further object is to provide such a new and improved device in which the seat is provided with a collapsible back member. Still another object is to provide a device of the foregoing character having an adjustable folding back rest prop which supports the backrest and adjusts for individual comfort and reclining when the device is opened, prevents tipping of the device when occupied, and provides a convenient handle for carrying the device when it is folded.
Another object is to provide such a new and improved device which folds compactly for storage or transport and provides a handle for carrying the device. Still another object is to provide such a new and improved device having an insulated container which may be lined and which may be securely attached to or incorporated within the seat portion of the chair so that perishable foodstuffs, ice, canned beverages, fishing bait, or other articles in the container will be conveniently accessible to the occupant of the seat.
It is a further object to provide a new and improved device in which the seat and backrest members are provided with collapsible armrest members which open to provide arm support and comfort when the device is opened. Still another object to provide such a new and improved device of the foregoing character which is durable and lightweight. An additional object is to provide such a new and improved device which is easy to manufacture and low in cost.
These together with other objects and advantages which will become apparent reside in the details of construction and operation as will be more fully described and claimed, reference being made to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout and in which:
Brief Description of the Drawings
The invention will hereafter be elucidated with reference to the drawings:

Detailed Description of the Invention
Turning now to the drawings, with particular emphasis to FIGS. 4 and 1, it will be seen that the chair of this invention may include a hollow rectangular integrated one piece seat portion 1 of injection moulded plastic, nylon, or other suitable material, which may be equipped with a front access panel or door 4 of plastic or other suitable material, which can be hingedly connected to the front portion of the seat at 11.
The access panel or door 4 may be secured with a manually turning lock 5 of metal, plastic, or similar material which may additionally serve as a knob which may be grasped for opening said access panel. The purpose of the lock being to prevent release of carried items, to prevent theft of said items, and to tightly secure and seal insulated compartment. The inner or compartment portion off the access panel 4 may be provided with insulating material 8 of plastic, polyurethane foam, or the like and may be provided with a lining material 10 of plastic, thermoplastic, or other suitable material.
The top portion of the seat 14 may be anatomically moulded as shown in FIG. 3 to the contour of the buttocks to provide added comfort to the occupant of the chair. Additionally, thermal insulating material 8 of polyurethane foam or similar insulating material, may be placed directly beneath and inside the top portion of the seat 14 and may also be placed on the inside bottom and sides of the hollow seat compartment. A protective and stiffening liner 9 of plastic, thermoplastic, or similar material, may be placed adjacent to the thermal insulating material 8 to protect the items contained in storage and to define the hollow inner compartment 12. The entire hollow seat portion may be inexpensively moulded in one piece so as to be lightweight, inexpensively made, and easily reinforced to prevent collapse when sat upon.
A back member 2 of wood, metal, plastic, or other suitable material may be hingedly secured at 6 by means of rivets, screws, or the like, to seat base member 1 whereby the back rest 2 may extend upward and back from the top of the seat portion 14 for use, as in FIG. 4, or may be folded upon the top of the seat portion 14 for storage, as in FIG. 2.
A U-shaped block member, back member support prop 3 of tubular aluminum construction, plastic, or other suitable material, may be hingedly secured by rivets, screws, or the like as shown at 7 to back member 2 whereby the support prop 3 may extend back from the seat portion 1 for greater reclining and comfort and additionally to prevent tipping of the device when occupied, or may be folded upon the lower rear portion of the back support member to become a convenient handle for carrying as in FIG. 2.
