Description
(a) TECHNICAL FIELD OF THE INVENTION
[0001] The present invention generally relates to grill ovens, and
more particularly to a grill oven that, after its foot stand is
collapsed, could be hand-carried or pulled along on the grill
oven's wheels.
(b) DESCRIPTION OF THE PRIOR ART
[0002] Barbecue is a widely popular outdoor activity, making
people's leisure life more interesting. However, for moving the
grill oven outside the house, transporting the grill oven to the
wilderness, and changing the place of barbecue, all require the
laborious movement of the grill oven.
[0003] The conventional grill ovens, even for those cart-type grill
ovens, are too heavy and bulky for outing and traveling. Even
though there are lightweight and portable grill ovens, their
functions are limited and their assembly/disassembly is rather
troublesome.
SUMMARY OF THE INVENTION
[0004] A novel grill oven is provided herein, which mainly contains
an oven body, an oven cover, a pair of seat pieces, a pair of
H-shaped stands, a pair of boards, two pairs of sliding rails, and
at least a pair of wheels. The seat pieces are provided along a
front bottom edge and a back bottom edge of the oven body,
respectively. The stands are provided along a left bottom edge and
a right bottom edge of the oven body, and hinged between the front
and back seat pieces, respectively, so that they could be folded
beneath the oven body. The pairs of sliding rails are provided so
that the boards could be slid laterally in and out of the left and
right sides of the grill oven, respectively, under the oven body.
On either a left or right end of the seat pieces, the wheels are
provided, respectively. After the H-shaped stands are folded under
the oven body and the boards are retracted, the grill oven could be
hand carried. Alternatively, the grill oven could be pulled on its
wheels by the handle on an un-retracted board opposite to the
wheels. Various fastening means and locking means are provided
between the oven cover and body, between the seat pieces and the
boards, and between the folded stands.
[0005] According to the present invention, the oven cover, the
H-shaped stands, the boards are joined to the oven body by various
pin-joining and sliding means so that the grill oven could be
easily and conveniently collapsed and expanded. Together with the
effortless pulling means, the for a large-scale grill oven, its
transportation convenience is still preserved.
[0006] According to the present invention, the boards could be
pulled out from under the oven body for placing various objects
such as food and utensils. Most significantly, handles are provided
on the boards and, by leaving one of the boards opposite to the
wheels un-retracted, the handle of the board could be used to pull
the grill oven.
[0007] The foregoing objectives and summary provide only a brief
introduction to the present invention. To fully appreciate these
and other objects of the present invention as well as the invention
itself, all of which will become apparent to those skilled in the
art, the following detailed description of the invention and the

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0026] The following descriptions are exemplary embodiments only,
and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
[0027] As shown in FIGS. 1 to 3, a grill oven according to an
embodiment of the present invention mainly contains an oven body
10, an oven cover 20, a front seat piece 30, a back seat piece 31,
a H-shaped left stand 40, a H-shaped right stand 41, a left board
50, a right board 51, a left pair of sliding rails 60, a right pair
of sliding rails 61, and at least a pair of wheels 70 and 71. The
oven body 10 has a side control panel 11 with a handle 12. Inside
the oven body 10, the common oven components such as a grill 13, a
plate 14, and a burner 15 could be provided. The front and back
seat pieces 30 and 31 are provided along a front bottom edge and a
back bottom edge of the oven body 10, respectively. The left and
right stands 40 and 41 are provided along a left bottom edge and a
right bottom edge of the oven body 10, and hinged between the front
and back seat pieces 30 and 31, respectively, so that they could be
folded beneath the oven body 10 or unfolded to support the oven
body 10. Along the inner surfaces of the front and back seat pieces
30 and 31, the left and right pairs of sliding rails 60 and 61 are
provided so that the left and right boards 50 and 51 could be slid
laterally in and out of the left and right sides of the grill oven,
respectively, under the oven body 10. Please note that there are
handles 50A and 51A along the outer edges of the left and right
boards 50 and 51, respectively, to facilitate the sliding of the
left and right boards 50 and 51. On the inner surface of either a
left or right end of the seat pieces 30 and 31, the wheels 70 and
71 are provided, respectively.
[0028] Fastening elements 80 are provided at the left and right
sides of the grill oven between the oven cover 20 and the oven body
10. Each fastening element 80 contains a hook piece 80A on the oven
cover 20 and a ring piece 80B on the oven body 10. The fastening
elements 80 could tightly join the oven cover 20 and oven body 10
together so that the grill oven could be securely transported. On
the other hand, when the H-shaped stands 40 and 41 are unfolded to
an upright position, pins 81 are provided to run through the front
and back seat pieces 30 and 31, and the H-shaped stands 40 and 41,
to securely lock them together. To move the grill oven, the pins 81
are removed so as to collapse the H-shaped stands 40 and 41.
[0029] As shown in FIGS. 4 and 4A, locking means 82 are provided to
the left and right sides of grill oven to secure the left and right
boards 50 and 51, respectively. Each locking means 80 contains a
latch 82D on the seat piece 30 or 31, and latch hole 82E on a front
or back side of the board 50 or 51. Each latch 82D contains a latch
seat 82A having an L-shaped latch bar 82C laterally slidable in a
sliding track 82B. Each latch 82D and its corresponding latch hole
82E are provided such that, when either the board 50 or 51 is fully
pulled out, the latch bar 82C could be slid into the latch hole 82E
along the sliding track 82B. The boards 50 and 51 are thereby
reliably locked in their extended position for placing various
objects on their top surfaces, without being accidentally pushed
and retracted under the oven body 10. To really retract the boards
50 and 51, using the board 50 as example, as shown in FIG. 4B, the
L-shaped latch bar 82C is turned so that it could be slid along the
sliding track 82B. The latch bar 82C is then moved away so that it
is not locked to the latch hole 82E, as shown in FIG. 5. Then, the
board 50 could be pushed, as shown in FIG. 6, until it is fully
under the oven body 10. As shown in FIG. 7, after the board 50 is
completely retracted, the L-shaped latch bar 82C is turned so that
it could be slid along the sliding track 82B and the latch bar 82C
is then moved so that it sticks out in front of the board 50 to
prevent the board 50 from accidentally sliding out.
[0030] After both the boards 50 and 51 are securely retracted as
described above, as shown in FIG. 8, the pins 81 are removed to
release the H-shaped stands 40 and 41's locking to the seat pieces
30 and 31. The H-shaped stands 40 and 41 are then folded towards
each other until they are flatly stacked under the oven body 10, as
shown in FIG. 9. Locking means 83 are provided between the H-shaped
stands 40 and 41 to reliably hold them together. Each locking means
83 contains a plug 83B on the stand 40 and a matching socket 43A on
the stand 41 at corresponding locations, respectively. Therefore,
when the stands 40 and 41 are folded and stacked together, the plug
43B is snapped into the socket 43A, as shown in FIG. 10, so that
the stands 40 and 41 are reliably joined to each other.
[0031] After the grill oven is collapsed as described above, the
grill oven could be hand-carried by the handle 12 as shown in FIG.
11. Alternatively, the grill oven could have only one of the boards
50 and 51 adjacent to the wheels 70 and 71 retracted and latched.
The grill oven then could be conveniently and effortlessly pulled
on the wheels 70 and 71 by the handle 50A or 51A of the
un-retracted board 50 or 51.
[0032] An alternative embodiment of the present invention is shown
in FIG. 13. For the H-shaped stand 40 that is adjacent to the
wheels 70 and 71, an additional pairs of wheels 72 and 73 are
provided to the front and back edges at a bottom end of the stand
40. As such, instead of using the wheels 70 and 71, the grill oven
could be conveniently and effortlessly pulled on the wheels 72 and
73 by the handle 50A or 51A of the un-retracted board 50 or 51 that
is adjacent to the wheels 70 and 71. As shown in FIG. 14, to
facilitate the stands 40 and 41's folding beneath the oven body 10,
the wheels 72 and 73 are configured so that they avoid the seat
pieces 30 and 31 when the stands 40 and 41 are folded.
[0033] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the spirit of the present invention.
