Portable adjustable chair with insulated seat cooler
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 an accessed, 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 require the occupant to sit near the ground and are sometimes provided with short legs. 
     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 both hold small articles and thermally insulate perishable foodstuffs and bottled beverages. 
     A number of alternative means have been proposed to overcome some of the difficulties with conventional chairs. For example, several chairs have been devised with storage capability for beach or camping. Siday U.S. Pat. No. 1,900,847 discloses a chair with a receptacle in the seat. Taipalus, U.S. Pat. No. 4,210,363 discloses a seat with insulation in a receptacle area. Similarly, McDole, U.S. Pat. No. 2,357,214 discloses a fishing tackle box and receptacle with seat platform. 
     A variety of tackle box chairs and beach chairs exist and while each serves a specific purpose, the alternative means provided require insulating and carrying means, and are sometimes difficult to access without standing. Many of the alternatives available suffer from tipping or require the occupant to sit very low to the ground, and some are quite cumbersome to carry. Still others are provided with a back prop of such a design as to cause the occupant serious injury if suddenly collapsed. 
     SUMMARY OF THE INVENTION 
     It is an object of this present invention to provide an adjustable foldable chair of the type 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, perishible foodstuffs, fishing bait, or other small articles. 
     It will be seen that the present invention overcomes some of these inadequacies by providing an easily grasped closure panel or lid to a seat platform with a thermally insulated compartment supported a comfortable distance from the ground by leg members, or bosses. 
     A further object is to provide a comfortable chair having easy access to the above mentioned compartment, cushioning and contoured seat portion, armrest support, and a padded shoulder strap for comfortable carrying. This comfort is further enhanced with an object being to provide varied reclining positions. 
     Another object is to provide a new and improved device which folds compactly and securely for storage and transport. 
     A further object is to provide a new and improved device which is lightweight, durable, easily maintained, 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, references being made to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout and in which:

     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 includes a hollow box like housing having an upper generally rectangular wall defining a seat platform 1 of injection moulded plastic, nylon, or other suitable material, which is defined by front, back, and side walls and an open front compartment, and lower generally rectangular wall. 
     An insulated closure panel of similar materials can be securely engaged to the seat platform to seal and insulate the seat compartment. The insulated closure panel or lid 4 may be engaged with liner 9 of plastic or similar materials at liner protrusion 20 and a lid recess contour 11. The lid 4 is preferably contour molded 27, so as to be easily grasped when engaging and disengaging. The inner portion of the lid 4 is preferably provided with insulating material 8 of polyurethane foam or similar insulating material and is protected with a lining material 10 of plastic, thermoplastic, or other suitable material. 
     The top portion of the seat platform 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, this top portion 14 is preferable covered with a cushioning material of soft polyethylene foam or other suitable material 28 as shown in FIG. 4. Thermal insulating material 8 of polyurethane foam or similar insulating material, is preferably placed on the inside bottom, rear, and sides of the hollow seat compartment 12 and directly beneath and inside the top portion of the seat 14. A protective and stiffening liner 9 of plastic, thermoplastic, or similar materials, is preferably placed adjacent to the insulation 8 areas to protect the items contained in storage and to define the hollow inner compartment. This liner 9 is ideally provided with contour 21 to prevent debris from collecting and to allow easy cleaning. The entire hollow seat portion may be inexpensively moulded in one piece and foamed in place so as to be lightweight, inexpensively made, and easily reinforced to prevent collapse when occupied. 
     A hardware plate or link connection 22 of metal or other suitable material is securely fastened to seat portion 1 at 29 by rivets, screws, or the like as shown in FIG. 2. A support strut or link connection 3 of wood, metal, plastic, or the like is pivotally secured at 6 by means of similar materials to hardware link plate 22 and to stabilizer prop 18. Said stabilizer prop 18 may be constructed of tubular aluminum, plastic, or other suitable material and is pivotally secured by similar means to U-shaped link plate 19 at 30. Said U-shaped plate 19 is constructed of metal or similar material and secures front link strut 17 at 15. Front link strut 17 is pivotally secured to seat platform side wall at 13. Slotted detent rack 5 may be constructed of metal, plastic, or other suitable material and may be integrated with armrests 16 of similar materials and said armrests 16 are pivotally secured at 7 by rivets, screws, or other similar materials.
