Description

CAMP STOVE WITH CONVERTIBLE BAFFLE AND SHELF

TECHNICAL FIELD OF THE INVENTION

(0001) The present invention relates to stoves, and more particularly relates to camp stoves.

BACKGROUND OF THE INVENTION

(0002) Portable camp stoves are often used by campers for preparing foods at a camp site. Typically, such camp stoves include a pair of burners, a fuel supply, a collapsible lid, and baffles to screen sides of the stove from wind. The baffles typically attach to the lid and are folded against the lid for storage. To store a camp stove, the baffles are folded to the lid, and the lid is folded over the stove burners. The burners are usually mounted within a firebox, and closing the lid over the firebox forms a box-like enclosure around the burners. The enclosure may then be stored in a cardboard box, or may be stored as is.

(0003) The fuel supply for conventional camp stoves is typically either kerosene or propane. If kerosene is utilized, the kerosene tank is typically mounted to the stove, for example along the front of the stove. The tank is typically disconnected during storage. For camp stoves that utilize propane, a propane bottle is typically attached to the camp stove, for example, at the front, back, or one of the sides of the camp stove. Again, like the kerosene tank, the propane bottle is typically removed during storage .

(0004) Although camp stoves work well for their intended purpose, often there is little-to-no storage space for items used in connection with the camp stove during operation of the camp stove. For example, in general, there is no place on a conventional camp stove to place cooking utensils, food, and food preparation items, absent placing the items directly on a cooking surface.

SUMMlUlY OF THE INVENTION

(0005) The following presents a simplified summary of some embodiments of the invention in order to provide a basic understanding of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some embodiments of the invention in a simplified form as a prelude to the more detailed description that is presented later.

(0006) In accordance with an embodiment, a camp stove is provided having at least one convertible baffle and shelf that may be positioned in one configuration to be used as a baffle and in another configuration to be used as a shelf. In an embodiment, a convertible baffle and shelf is hinged to one side of a firebox of the camp stove. The convertible baffle and shelf is folded upward and attached to a lid for the camp stove to serve as a baffle. The convertible baffle and shelf is folded downward, to a position horizontal with the ground, so that it may be used as a shelf. In an embodiment, the baffle extends outward away from the camping stove when it serves the shelf function. However, in an alternate embodiment, the baffle may fold inward relative to the stove surface to serve the shelf function. (0007) Other features of the invention will become apparent from the following detailed description when taken in conjunction with the drawings, in which:

BRIEF DESCRIPTION OF THE DRAWINGS

(0008) FIGURE 1 is a side perspective view of a camp stove incorporating an embodiment of the invention, the camp stove shown in a closed configuration; and

(0009) FIG. 2 is a side perspective view of the camp stove of FIG. 1, with the camp stove opened.

DETAILED DESCRIPTION

(0010) In the following description, various embodiments of the present invention will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the present invention may be practiced without the specific details. Furthermore, well- known features may be omitted or simplified in order not to obscure the embodiment being described.

(0011) Referring now to the drawings, in which like reference numerals represent like parts throughout the several views, FIG. 1 shows a camp stove 20 incorporating an embodiment of the present invention. As can be seen in FIG. 2, the camp stove 20 includes a firebox 22, having situated along its upper surface a grill 24 and a griddle 26. In the embodiment shown, the stove 20 includes two burners 28, only one of which is shown in FIG. 2. However, aspects of the present invention may be utilized in a camp stove having one burner, or more than two burners. Moreover, aspects of the present invention may be utilized in a camp stove having just one or more grill surfaces, just one or more griddle surfaces, any combination of grill and griddle surfaces, and/or a camp stove having cooking surfaces other than grills or griddles. (0012) The camp stove 20 includes a pair of control knobs 30, 32 mounted on the front of the firebox 22. In the embodiment shown, a propane bottle 34 is attached to a right rear section of the firebox 22. However, aspects of the present invention may be utilized with a camp stove using other fuel sources, including but not limited to kerosene, other liquid or gas sources, and/or charcoal grills.

(0013) In the embodiment shown, the camp stove 20 includes a lid 40 connected to the firebox 22 by a latch 42 and hinges (not shown, but known in the art) . The lid 40 may be closed when the burners 28 are off, and provides protection for the burners. Closing the lid 40 over the firebox 22 forms a box-like enclosure around the burners 28. The box-like enclosed camp stove 20 may then be stored in a cardboard box, or may be stored as is.

(0014) The camp stove 20 also includes left and right convertible baffles and shelves 44, 46. In the embodiment shown, the convertible baffles and shelves 44, 46 are substantially planar, and each includes a rounded bottom 48. Angled brackets 50 extend from the bottom edge of the rounded bottom 48 into slots 52, 54 at outer, upper edges of the firebox 42. The angled brackets 50 are received in the slots 52, 54 in such a manner so that the convertible baffles and shelves 44, 46 may be rotated about an axis extended parallel with the rounded bottom 48 of the convertible baffles and shelves 44, 46.

(0015) A rear upper edge of each of the baffles 44, 48 includes a slotted opening 56. The slotted opening 56 is arranged and configured to fit onto protrusions 58 on the underside of the lid 40.

(0016) In use, the convertible baffles and shelves 44, 46 are stored in a flat position against the top of the grill 24 and the griddle 26. This position is shown in phantom in FIG. 1 for both of the convertible baffles and shelves 44, 46 and again is shown in phantom in FIG. 2 for the right convertible baffle and shelf 46.

(0017) To utilize the convertible baffles and shelves 44, 46 as wind blocks (i.e., baffles), the lid 40 is raised, and each of the convertible baffles and shelves is raised so that it extends vertically. The left convertible baffle and shelf 44 is shown in this position in FIG. 2. To lock the convertible baffles and shelves 44, 46 in this position, the slotted openings 56 are fitted onto the protrusions 58. In this manner, the convertible baffles and shelves 44, 46 may both be raised and attached to the lid 40 so that the three elements serve as a three-sided wind block for the cooking surface of the camp stove 20, i.e., in the embodiment shown, the grill 24 and the griddle 26.

(0018) To utilize one of the convertible baffles and shelves, such as the convertible baffle and shelf 46, as a shelf, the convertible baffle and shelf may be folded inward to the position shown in phantom in FIG. 2. In this position, the shelf extends over the griddle 26. It is not recommended that the stove 20 be operated with the griddle 26 hot and the convertible baffle and shelf 46 in the folded inward position, but the convertible baffle and shelf 46 may be used in its folded inward position when, for example, only the grill 24 of the stove 20 is in operation. In this configuration, items may be placed on the back side of the convertible baffle and shelf 46, such as food, food preparation items, cooking utensils, or other items.

(0019) In another shelf configuration, the convertible baffle and shelf 46 is folded outward to the position shown in FIG. 2. In this position, the angled brackets 50 and the rounded bottom 48 engage the top and outer surfaces of the firebox 22, and prevent further rotation of the convertible baffle and shelf 46 downward. Thus, the convertible baffle and shelf 46 extends outward, in a horizontal direction. The convertible baffle and shelf 46 may thus be used as a shelf, and may receive many items, such as the items listed above. The convertible baffle and shelf 44 may similarly be utilized as a shelf in this manner.

(0020) Although one type of convertible baffle and shelf is shown in the drawings, other configurations are contemplated. For example, convertible baffle and shelf may include a lock for locking the baffle into the shelf position, and may include a chain or some other member that suspends the baffle in the open position. In addition, although a single type of hinge is shown, alternate hinge systems may be used. Further, a convertible baffle and shelf may be used in which the convertible baffle and shelf does not hinge to the firebox 22, but instead connects or is otherwise rearranged to provide baffle and shelf functions. As one example, a baffle may be removable, and may be connected in a first vertical position to act as a baffle, and in a second horizontal position to act as a shelf.

(0021) Other variations are within the spirit of the present invention. Thus, while the invention is susceptible to various modifications and alternative constructions, a certain illustrated embodiment thereof is shown in the drawings and has been described above in detail. It should be understood, however, that there is no intention to limit the invention to the specific form or forms disclosed, but on the contrary, the intention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention, as defined in the appended claims.
