The present disclosure provides a barbecue having at least one storable shelf rotatable about a generally vertical pivot axis between a storage position inside the housing of the barbecue and a use position at the outside of the barbecue housing. The housing of the barbecue has an open upper end and inner and outer surfaces. A 20 mounting assembly is mounted on the inner surface of the housing adjacent the open upper end and has a generally vertical aperture therein. The at least one shelf includes an elongated shelf bracket having a shaft extending downwardly from an end thereof, with the shaft being rotatably received within the generally vertical aperture in the mounting assembly. A flat, generally disk-shaped shelf is mounted on the elongated 25 shelf bracket. The rotatable receipt of the shaft within the generally vertical aperture enables pivoting movement of the elongated shelf bracket relative to the mounting assembly to swing the shelf between a storage position inside the housing and a use position outside the housing. The housing has a rim at the open upper end thereof between the inner and outer 30 surfaces. The elongated shelf bracket has a recess therein at the end thereof adjacent the shaft which receives the rim of the housing to seat the shelf bracket on the rim when the shelf is swung into the use position outside the housing. The elongated shaft bracket also has a portion thereof adjacent the recess which rests on and is supported by a handle mounted on the outer surface of the housing when the shelf is in the use position 35 outside the housing. A second recess in the elongated shelf bracket receives the lower edge of a lid which may be placed over the open upper end of the housing, when the shelf is in the use position outside the housing. Preferably, the barbecue has a pair of the shelves mounted on opposite portions of the housing. The pair of shelves are positioned, one over the other, 5 for storage inside the housing when each of the shelves is swung into the storage position. When in the use positions, each of the shelves extends outwardly from the opposite sides of the barbecue housing. The barbecue has an opposite pair of the handles which provide support for the elongated support brackets of the shelves in addition to the positioning of the rim within the 10 recesses in the elongated support brackets when the shelves are in the use position outside of the barbecue housing. Description of the Figures FIG. 1 is a front sectional view of a barbecue with storable shelves in accordance with the invention. 15 FIG. 2 is an exploded perspective view of one of the shelf assemblies of the barbecue of FIG. 1. FIG. 3 is an enlarged sectional view of a portion of FIG. 1 showing the details of the manner in which one of the shelf assemblies is positioned and supported when in the use position outside of the barbecue. 20 FIG. 4 is a front sectional view similar to the view of FIG. 1 but with the two shelf assemblies positioned in overlapping relation for storage within the barbecue. Detailed Description of the Invention FIG. 1 shows a barbecue having storable shelves in accordance with the 25 invention. The barbecue 10 includes a housing 12 mounted at the top of an upright stand 14. The housing has an upper open end 16 having a circular rim 18 between an inside surface 20 and an outside surface 22 of the housing 12. The open upper end 16 may be enclosed by a mating lid 24 which can be placed over the rim 18 of the housing 12. 30 The barbecue 10 includes a grate 26 positioned at the inside of the housing 12 just below the rim 18. Food to be cooked is placed on the grate 26 3 and is heated by charcoal containing apparatus 28 positioned below the grate 26. Such details are unimportant to the storable shelves in accordance with the present invention. However, reference is made to co-pending application Serial No. 10/359,804 filed on February 7, 2003 by Alan D. Crawford et al. and 5 entitled "QUICK START BARBECUE", for a detailed example of a barbecue which may be used with the storable shelves in accordance with the present invention. In accordance with the invention, the barbecue 10 has a pair of opposite shelf assemblies 30 and 32 mounted on the housing 12 at opposite sides thereof. 10 The shelf assemblies 30 and 32 are pivotable about vertical axes, and can be swung between use positions outside of the housing 12 and storage positions within the housing 12. The shelf assemblies 30 and 32 are shown in the use positions outside of the housing 12 in the view of Fig. 1. When in the use positions, the shelf assemblies 30 and 32 extend outwardly from the opposite 15 sides of the housing 12 with a function to receive and support food containers, cooking utensils and other such objects. When the shelf assemblies 30 and 32 are swung to the opposite storage positions, they reside in overlapping relation for storage within the housing 12, as shown in Fig. 4. Fig. 2 is an exploded perspective view of one of the shelf assemblies 30. 20 The other shelf assembly 32 is of identical configuration. As shown in Fig. 2, the shelf assembly 30 includes an elongated shelf bracket 34 on which is mounted a shelf 36. In the present example, the shelf 36 is of thin, disk-shaped configuration, and is secured to the shelf bracket 34 by a plurality of screws 38 which extend upwardly through holes 40 in the elongated shelf bracket 34 and 25 into the shelf 36. The elongated shelf bracket 34 has an end 42 which extends by a small amount beyond an adjacent edge 44 of the shelf 36. The end 42 has a generally cylindrical shaft 46 extending downwardly therefrom. The end 42 of the shelf bracket 34 also has a recess 48 therein adjacent the shaft 46. 30 As shown in Figs. 1 and 4, the barbecue 10 is provided with an opposite pair of mounting assemblies 50. The mounting assemblies 50 which are mounted on the inside surface 20 of the housing 12 just below the rim 18 of the 4 open upper end 16 are each provided with a vertical aperture 52 extending downwardly therethrough. Each of the vertical apertures 52 is of generally cylindrical configuration and receives a shaft 46 of the shelf bracket 34 of one of the shelf assemblies 30 and 32. The shafts 46 are free to rotate within the 5 apertures 52, thereby permitting the shelf assemblies 30 and 32 to undergo swinging motion between use positions outside the barbecue housing 12 and the storage positions inside of the housing 12. The shafts 46 can also undergo vertical movement relative to the apertures 52, permitting the shelf assemblies 30 and 32 to be raised for movement between the storage and use positions as 10 well as for storage in overlapping relationship within the housing 12 as described below. Fig. 3 is a detailed view of the right hand shelf assembly 32 when in the use position outside of the barbecue housing 12. In this position, the rim 18 of the housing 12 extends into the recess 48 of the elongated shelf bracket 34, 15 enabling the shelf assembly 32 to nest on the rim 18. At the same time, a portion 54 of the shelf bracket 34 rests on a handle 56 attached to the outside surface 22 of the barbecue housing 12, to provide further support for the shelf assembly 32. The left hand shelf assembly 30 functions in similar fashion, and nests on the rim 18 and is supported in part by a handle 58 mounted on the 20 outside surface 22 of the barbecue housing 12 opposite the handle 56. As shown in FIG. 3 each of the elongated shelf brackets 34 has a recess 60 extending therein from an upper surface thereof adjacent the first recess 48. The recess 60 receives a lip at a lower edge of the lid 24 therein when the shelf is in the use position and the lid 24 is placed over the open upper end 16 of the 25 housing 12. The opposite shelf assemblies 30 and 32 are placed in the use positions outside of the barbecue housing 12 by lifting and then lowering each shelf assembly 30 and 32 as necessary so that the recess 48 in each shelf bracket 34 is positioned over the rim 18 of the housing 12, and the portion 54 of each is 30 disposed on a respective one of the handles 56 and 58. This position is shown in Fig. 1 as well as in the detailed view of Fig. 3. 5 Movement of the shelf assemblies 30 and 32 into the housing 12 for storage therein is accomplished by again lifting each of the shelf assemblies 30 and 32 as necessary so that the rim 18 is free of the recess 48 in each of the shelf brackets 34. Each of the shelf assemblies 30 and 32 is then swung 5 inwardly, allowing the shafts 46 to rotate within the vertical apertures 52 in the mounting assemblies 50, until the shelf assemblies 30 and 32 are disposed at the inside of the housing 12. The shelf assemblies 30 and 32 are moved into the storage position at the inside of the housing 12 in succession, with one being moved into the storage position followed by the other being moved into the 10 storage position. In the example of Fig. 4, the right hand shelf assembly 32 is the first to have been moved into the storage position. Where it reaches the interior of the housing 12, the shelf assembly 32 is lowered onto the grate 26. Again, upward and downward movement of the shelf assemblies 30 and 32 as they are swung back and forth in this fashion is permitted by vertical 15 movement of the shafts 46 within the vertical apertures 52. Following disposition of the right hand shelf assembly 32 onto the grate 26, the left hand shelf assembly 30 is raised and swung to the inside of the housing 12 where it is placed on top of the first shelf assembly 32. The order of placement of the shelf assemblies 30 and 32 at the interior of the housing 12 is unimportant, and the 20 left hand shelf assembly 34 can be positioned there first with the right hand shelf assembly 32 being next swung into the interior of the housing 12 for placement on top of the shelf assembly 30. 6
