 8 Claims, 9 Drawing Figures iivvirvv 111 PMENTED SHEET 2 1F 2 COOLER HAVING APPARATUS FOR SELECTIVELY STORING OR DEPLOYING TRAYS BACKGROUND OF THE INVENTION The present invention relates generally to coolers for picnicking and the like, and more particularly to an ice chest having trays which are selectively stored or used.  
  The main problem in picnicking or the like is the one of striking a satisfactory balance between having all of the conveniences that are desired on such an outing without the problem of having so much equipment that it would be impractical or unpleasant to transport this equipment to the outing site.  
  For most people who go on outings of this type having cold drinks along is a luxury to which they have become accustomed. Because of the development of ice filled coolers, the cooler has practically replaced the old fashion picnic basket because of this facility to keep drinks cold and to preserve food. With a container such as a picnic basket it was, however, possible to place a table or ground cloth such as a blanket therein, and to store the needed utensils such as knives, forks, spoons, paper plates, and paper cups in a picnic basket without subjecting them to the moisture present in an ice chest. This moisture can, of course, be damaging to these items. Consequently, in order to have the best of both worlds it has been necessary for modern picnic goers to take both a cooler and some other container such as a picnic basket to carry the other needed items.  
  Another problem is encountered if the outing scene does not include picnic tables or a surface from which to eat. Typically, in the absence ofa picnic table or the like, ground cloths or blankets are spread and the picnic proceeds by having the participants hold their own plates while eating, or being forced to set the plates, cups, etc. on the ground or ground cloth. Additionally, this normal picnic arrangement requires an extensive amount of space, and, irrespective of the placement of the cooler with respect to the picnic participants, normally renders the cooler inaccesible or inconveniently located to at least some of these people. If the picnic is on a small boat or the like, this inconvenience is amplified.  
  While using trays on a picnic would be more convenient than not, they are rarely used because it means an additional bulky item to transport; and the problem of how to hold the tray or where to set it when eating therefrom still remains. For this reason, trays are usually not seen at a picnic.  
 SUMMARY OF THE INVENTION The present invention relates to an ice chest or cooler which has trays thereon which are selectively stored for transportation by a novel stacking and fastening arrangement on the lid thereof, or used, by being attached to the sides of the ice chest or cooled by a novel connection structure.  
  An object of the present invention is to provide a satisfactory substitute for a portable picnic table in combination with a cooler.  
  Another object of the invention is to provide a picnic tray system which allows simultaneous access to a cooler or ice chest.  
  A further object of the invention is to provide an ice chest with trays thereon which are selectively stored or used.  
  Still another object of the invention is to provide a lightweight and compact storage compartment in asso ciation with an ice chest or cooler.  
  Other objects, advantages, and novel features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawmgs.

  FIG. 6 shows the connection structure of the tiedown strap to the lid of the cooler;  
  FIG. 7 is a top plan view of the ice chest invention with the trays in a storage position as shown in FIG. 5, but without the strap device being fastened;  
  FIG. 8 is a cross-sectiona| view of tray ll taken along line 8--8 of FIG. 1; and  
  FIG. 9 is a perspective view of the cup holder of the present invention.  
 DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, and more particularly to FIG. 1 which shows the general combination of a cooler 10 and trays II in the deployed position. FIG. 2 shows the connection arrangement 12 of the trays 11 to the container or body 13 of the ice chest. The top or lid 14 can be in the open or closed position while the trays are so disposed, or when the trays are in the storage position. Braces l6 serve to stabilize the trays II.  
  The trays 11 have indentations therein which can best be seen in FIGS. 1 and 8. A central depression 17 is larger than the other depressions and is for a paper plate or the like. Similarly, indentations I8 and I9 can be used for cups or the like. lndentations 2I and 22 are designed for side dishes, such as potato chips or jello, but it will be understood that the depressions canbe interchangeably used for different types of food or drink as desired.  
  FIG. 4 shows a strip 23, one of which is attached to each side and the ends of the ice chest body 13 by a plurality of sheet metal screws 24. A groove 26 is disposed in the strip 23 for receiving an elongated protuberance 27 on each tray 11. Additionally, the brace member 16 is received in an opening 28 formed by a bracket 29 (FIGS. 2 and 3) on the bottom of tray ll. Another opening 31 is formed by an inverted scoop shaped member 32 on the bottom of tray 1] and is located at a position remote from bradket 29 to thereby stabilize the tray II.  
  To utilize the trays II, the brace 16 may be placed upon the bottom of tray 11 either before or after the protuberance 27 is placed into the groove 26. Preferably, the protuberance 27 is slid into the groove 26 from the side thereof first, and the brace 16 is then put in place thereafter. Alternatively. the strips 23 and/or the trays can be made of a resilient material such as polyethylene plastic such that the protuberance 27 can be squeezed into the groove 26 by deforming either the protuberance 27 or the edges of the groove 26, or both, so as to form a snap fit. In placing the brace 16 on the tray 11. an extension 33 of brace 16 (FIG. 3) extends into the opening 28, and an extension 34 of the brace 16 extends into the inverted scoop shaped member. The bottom of brace 16 abuts the sides or ends of the cooler body I3.  
  In order to store the trays ll. they are stacked with the top side down as shown in FIG. 5. Then they are placed in a compartment 36. which may be made of any suitable material such as cloth or canvas. with a flap 37 having snaps 38 thereon. Compartment 37 serves to keep the trays clean and free from dust and other particles in the air which might render them unsanitary. A second compartment 39 is attached to the first compartment 36, and is to be utilized for storing eating utensils. As in the first compartment 36, second compartment 39 has a flap member 41 with snaps 38 thereon. A third compartment 42 is also attached to the first compartment 36, and is for storing the braces 16, when these braces are not in use. Compartment 42 has a similar flap 43 which is selectively closed by snaps 38.  
  The trays II and the first. second and third compartments 36. 39 and 42 are placed upon the lid 14 for storage and transportation as seen in FIG. 5. Brackets 44 are fastened to the lid 14 by screws 46, which pass through openings 47 in the bracket 44. The strap 48 (FIGS. and 6) is preferably made ofa nylon cloth and has a buckle 49 (FIG. 5) which is utilized to securely fasten the trays and compartments to the lid of the cooler It). Because ofthis arrangement. the lid may still be opened either with or without the trays stacked thereon. and whether or not the trays are deployed for use around the cooler as shown in FIGS. 1 and 2.  
  Also. on the inside of one of the back corners of the cooler is disposed a cup holder bracket 51, for holding stacks of cups 52. This cup holder bracket 51 may be attached to the inside walls of the ice chest in any suitable fashion. such as by screws 53.  
  It can therefore be seen that the instant invention provides an extremely versatile and compact recreational device. Besides the fact that it can be used as any ordinary cooler can be used. it can also be seen that people can conveniently carry everything needed for a modern picnic outing in one light and compact device. Four people can have individual trays 11 from which to dine (FIGS. 1 and 2) or a larger number of people can use the trays as a table like surface. Cooler top 14 may also be used as a table-like surface. and additionally. it  
 can be closed and yet be available to allow immediate access to the inside of the cooler body or container 13. In this way. food and drink may remain in the cooler longer and thereby kept cold until the actual time that it is needed. Also. the people dining under this arrangement do not need to have any special balancing skills, because of the fact that the trays are readily fastened to the cooler. In this way, the instant invention serves to replace a table, so that people sitting therearound have an elevated surface from which to dine. In a limited recreational setting such as on a small boat. it can be readily seen that space is conserved and convenience is enhanced.  
  Obviously many modifications and variations of the present ivention are possible in light of the above teachings. It is therefore to be understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
