ABSTRACT:
FIELD OF THE INVENTION
This invention relates generally to a portable cooking stove for use in motion filled, non-stable, environments such as boats, ships, and recreational vehicles. More particularly, the present invention relates to a small stove that is especially suitable for marine use in that the vessel or container, (usually a pot or pan) holding the food or liquid to be cooked or warmed is gimbaled to swing about perpendicular axes to remain upright despite substantial rolling or pitching of the boat and the movement of the recreational vehicle to prevent the spilling of the food being cooked or warmed.
BACKGROUND OF THE INVENTION
The prior art includes numerous small stoves which are gimbal mounted to enable the vessel or container (pot or pan) holding food or liquid to remain upright during rolling or pitching of a boat or movement of a recreational vehicle. A principal consideration for such a stove is safety to minimize potential fire hazards and the possibility of persons near the stove burning themselves by contact with hot parts or from spillage of material from the container, pot or pan. Several such patents are disclosed in United States patents as exemplified by U.S. Pat. No. 2,520,412 to Jensen; U.S. Pat. No. 4,445,495 to Frost; U.S. Pat. No. 4,653,462 to DeFoe; and U.S. Pat. No. 4,776,318 to Serra.
The Jensen patent discloses a cooking apparatus for a ship that will maintain the cooking container horizontal while the ship pitches or rolls. The cooking apparatus of Jensen is supported from a vertical wall of a galley and is provided with rotary supports vertically and horizontally disposed and adapted for holding a cooking container (pot or pan) horizontally when the ship pitches or rolls. The Frost patent discloses a cooking stove that is supported from a bulkhead (vertical wall) and is suitable for marine use in that its cooking container is gimbaled to swing about perpendicular horizontal axes to maintain the cooking container upright and horizontal notwithstanding the tilting of the bulkhead. The DeFoe patent discloses a galley stove having a gimbal mounting to accommodate the roll and pitch of a ship or boat on which the stove is used. The Serra patent discloses a portable cooking device having retainer means for partially surrounding a pot or pan above a burner to prevent the pot or pan from sliding from the cooking device.
While there are numerous cooking stoves for use in a motion filled, non-stable, environment such as boats, ships and recreational vehicles, most are complex, and all suffer from numerous deficiencies and disadvantages. The present invention overcomes these deficiencies and disadvantages in that it fills the needs for a simple, inexpensive, stove that can be used for cooking and warming purposes and can be easily mounted to existing or modified structures within boats, ships, and recreational vehicles.
SUMMARY OF THE INVENTION
In accordance with the present invention there is provided a portable cooking stove that is especially suitable for marine and recreational vehicle use in that the vessel or container, (pot or pan) holding food or liquid to be cooked or warmed is gimbaled to swing about perpendicular axes to remain upright despite substantial rolling or pitching of a marine vehicle and the movement of a recreational vehicle to prevent the spilling of the food being cooked or warmed.
The portable stove of the present invention generally comprises a gimbal ring having two sets of gimbals or bearings therearound, a frame associated with one set of gimbals or bearings for pivotally supporting the gimbal ring, a hanger assembly associated with the other set of the gimbals or bearings and being pivotally supported by the gimbal ring, a fuel supply tank mounted within a basket formed in a lower section of the hanger assembly, a burner assembly connected with the fuel supply tank, a cooking pot or pan within the hanger assembly, and means, such as a pedestal or opening within the marine or recreational vehicle, associated with the support frame for normally for maintaining the support frame in a vertical position. The structure of the cooking stove of the present invention is such that the axis of the pedestal or opening within the marine or recreational vehicle and the axis of the gimbal ring are in vertical alignment.
Accordingly, it is an object of the present invention to provide a portable cooking stove made of readily available, inexpensive, materials for preventing the spillage of the food or liquid being cooked or warmed by the stove.
It is a further object of the present invention to provide a portable cooking stove which incorporates gimbal mechanisms which allow the pot or pan holding the food or liquid to remain in a substantial level position if there is any movement, pitching or rolling of the vehicle supporting the portable cooking stove.
It is yet a further object of the present inventor to provide a portable cooking stove which incorporates retainer means which prohibit a pot or pan from sliding if the pot or pan had a tendency to slide.
It is still a further object of the present invention to provide a portable cooking stove of simple construction and made of readily available materials, which further incorporate a shield for making its burner less susceptible of being extinguished by wind gusts.
