DETAILED DESCRIPTION OF THE INVENTION:
[0024] As required, detailed embodiments of the present invention
are disclosed herein; however, it is to be understood that the
disclosed embodiments are merely exemplary of the invention that
may be embodied in various forms. The figures are not necessary to
scale, some features may be exaggerated to show details of
particular components. Therefore, specific structural and
functional details disclosed herein are not to be interpreted as
limiting, but merely as a basis for the claims and as a
representative basis for teaching one skilled in the art to
variously employ the present invention.
[0025] FIG. 1 shows a barbecue having storable shelves in
accordance with the 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 ann 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.
[0026] The barbecue 10 includes a grate 28 positioned at the inside
of the housing 12 just below the rim 18. Food to be cooked is
placed on the grate 26 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
Ser. No. 10/359,804 filed on Feb. 7, 2003 by Alan D. Crawford et
al. and entitled "QUICK START BARBECUE", for detailed example of a
barbecue which may be used with the storable shelves in accordance
with the present invention.
[0027] 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. The shalf 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 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 relations
for storage within the housing 12, as shown in FIG. 4.
[0028] FIG. 2 is an exploded perspective view of one of the shelf
assemblies 30. 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 a flat, disc-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 into the shelf 36.
[0029] 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.
[0030] 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 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 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 shaft 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 well as for storage in overlapping
relationship within the housing 12 as described below.
[0031] 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, enabling the shelf assembly
32 to rest on the rim 18. At the same time, a portion 54 of the
shelf bracket 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 outside surface 22 of the barbecue
housing 12 opposite the handle 56.
[0032] 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
housing 12.
[0033] 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 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.
[0034] 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 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 inside 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 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 movement of the shafts 46 within the vertical
aperture 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 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
assembly 30.
[0035] Numerous modifications and variations of the present
invention are possible in light of the above teachings. It is
therefore to be understood that within the scope of the attendant
claims attached hereto, this invention may be practiced otherwise
than as specifically disclosed herein.
