The subject invention relates to a device for reducing or preventing unwanted movement of a pot or other cooking vessel on a stove. In particular, the present invention relates to a cooking vessel retaining device for use on stoves that are portable or built in to a vehicle.
Portable cooking appliances, such as stoves, are used all over the world in many environments. For example, people who enjoy camping, boating, sailing, or traveling by RV desire a small, portable stove for preparing meals while in transit or in a location that is remote from any working kitchen. Portable stoves take the form of electric, induction, gas-burning, etc. depending on, for example, whether the stove is mounted in a vehicle such as an RV or boat.
When meals are being prepared in a moving vehicle, such as a boat or RV, there is a significant danger that a cooking vessel being used on the stove may slide off of the stove and create a spill or other dangerous condition. (In the present application, a “cooking vessel” means any pot, pan, or other device used to hold or contain food to be heated or cooked). Such a dangerous condition may also occur if the stove is used on an uneven or excessively soft surface, such as one that may be encountered while camping. For this reason, portable stoves are often equipped with a device or system intended to prevent or reduce unwanted movement of the cooking vessels. Many such devices are known in the prior art, but these devices are excessively complicated to manufacture, assemble, and use.
For example, U.S. Pat. No. 2,379,206 to Westlake discloses a means for holding cooking vessels on galley stoves that includes arms mounted on bars that are mounted on a rail. The arms are intended to partially wrap around a cooking vessel, and are designed with varying shapes and lengths. The position of the arms is set by means of wing nuts. The complexity and difficulty of use of the Westlake system is apparent, however, from
U.S. Pat. No. 5,575,445 to Kozdas discloses a system for use with a conventional stove in which a clamping device for grasping the handle of a cooking vessel is provided. The system utilizes claws mounted on a collar that is in turn slidably mounted on a vertical support member. The claws are curved and spring biased for clamping onto the handle of a cooking vessel. The mounting collar may be locked into position on the support member by a pressure fit system, a cam system, or a screw-type system. The support member is attached to a rail mounted along the side of the stove. Again, however, the system is complicated and relatively difficult to use. In order to secure a single cooking vessel, the position of the support member on the rail must be adjusted, the position of the mounting collar on the support member must be adjusted, and the positions of the claws must be adjusted.
Clearly, the devices known from the prior art for reducing the amount of unwanted movement of cooking vessels on a portable stove are excessively complicated and difficult to use. This excessive complication and difficulty of use serves to discourage use of the devices, even on stoves that are equipped with them, thereby perpetuating the unsafe condition the devices were intended to alleviate.
Thus, what is needed is a simple but effective device for reducing the amount of unwanted movement of a cooking vessel on a stove. The device should be simple to manufacture, simple to install, and simple to use. The device should be inexpensive, but should not detract significantly from the aesthetic value of the stove with which it is associated.
Accordingly, it is an object of the present invention to provide a device for increasing the safety of stoves used on moving vehicles or in other unstable conditions.
It is yet a further object of the present invention to provide a cooking vessel retaining device that is simple to manufacture, install, and use.
It is still another object of the present invention to provide a cooking vessel retaining device that does not detract from the aesthetic value of the stove with which it is associated.
These and other objects are achieved by a first embodiment of the invention, by provision of a device for securing at least one cooking vessel placed in at least one cooking zone of a stove, where the device comprises: at least one support member proximate to the at least one cooking zone; at least one retaining member for contacting the at least one cooking vessel when the at least one retaining member is in an active position.

The invention and its particular features and advantages will become more apparent from the following detailed description considered with reference to the accompanying drawings.
a is an end view of the support member shown in
The stove 10 includes an electric heating element 12 for creating a cooking zone into which a cooking vessel can be placed to be heated. Of course, the present invention is advantageously applied to any type of stove, including induction, gas-burning, wood-burning, alcohol-burning, combination electric and alcohol-burning, and the like. In some embodiments, a substantially flat stovetop surface is provided above the heating element, such as when an induction or electric heating element is used.
The stove 10 includes a lid 13 for covering the heating element and stove 10 when the stove is not in use. The lid 13, in the embodiment shown in
In the embodiment shown in
Also mounted on the housing 11 are controls 40, 41 for operating the heating element 12, and an operation light 42. These features are also covered and protected by the lid 13 when it is in the closed position.
The support member 14, which is in the form of a rail, has a channel 18 running along its length. In other embodiments, the support member 14 is in the form of a ledge and can take a variety of different configurations. In the embodiment shown in
In the embodiment shown in
In some embodiments, only a single retaining member 19 is used. In such embodiments, a stationary rod or ledge along one side of the stove 10 serves to bear against one side of the cooking vessel while a single retaining member 19 may be slid into place against the other side of the cooking vessel.

The details of the anchoring mechanisms 20 are shown in
When it is desired to move the retaining members into the stowed position, to allow for closing of the lid 13, for example, first the anchoring mechanisms 20 are loosened on the front surface of the support. Then, the retaining members are slid to a position directly beneath the notches 22. Next, the retaining members are lifted and rotated upwards so that the elongated portions of the retaining members enter the notches. This position is shown in phantom in
The support member 14 shown in
a shows an end view of the support member 14. The clamp portion 23 is used to hold an edge of the lid 13, and is provided with a seat 23a for holding a flange on the edge of the lid 13. In some embodiments, the lid is bolted or adhered to the support member 14. At the top of the support member 14, the cross-section of the channel 18 is shown to be circular 25. In other embodiments, the channel has a differently shaped cross-section, such as square or ovoid. In such circumstances, the design of the retaining members is also different to allow movement between the active and stowed positions. Of course, the circular cross-section is particularly advantageous for allowing rotation of the retaining members 19 from the active to the stowed positions.
In embodiments in which the channel 18 in the support member 14 is square or ovoid, such that rotation of the protrusion 29 relative to the channel is not possible, the protrusion 29 itself includes features to allow rotation of the elongated portion 21 relative to the protrusion 29. For example, in one embodiment, a ring is attached to the end of the elongated portion 21 which is permitted to rotate freely relative to a protrusion having a square cross-section.
