The present application relates generally to cooking utensils, and more particularly, to cooking utensils for cooking food items over an exposed flame.
Cooking utensils are often used to assist in preparing food using a heat source, allowing a user to distance him or herself safely away from the heat source. For instance, cooking utensils may be used in situations where the heat source includes an exposed flame, such as a campfire, while allowing the user to be distanced from the flame. However, cooking over an open flame may present challenges, as the flame presents a direct heat source that is relatively difficult to regulate, and may inconsistently cook food.
The present application discloses a cooking utensil for cooking a food item over an exposed or open flame, such as a campfire. The utensil includes a movable or slidable shield element that can be selectively moved between a retracted position, where the food item is fully exposed at the end of the utensil, and an extended or shielding position, where the shield element or shroud at least partially circumscribes or surrounds the food item to limit or control heating of the food item when the shield element and food item are placed at the open flame. The shield element comprises a metal sheet (formed to the desired shape that circumscribes or at least partially circumscribes or surrounds the food item when the shield element is in the extended position) that optionally includes a plurality of apertures therethrough and optionally a plurality of different sized apertures therethrough to allow heat to pass through the shield element while limiting the flames from directly heating or burning the food item and providing enhanced and more uniform heating of the food item.
These and other objects, advantages, purposes and features of the present invention will become apparent upon review of the following specification in conjunction with the drawings.
The drawings described herein are for illustrative purposes only of selected configurations and are not intended to limit the scope of the present disclosure.
Corresponding reference numerals indicate corresponding parts throughout the drawings.
Referring now to the drawings and the illustrative embodiments depicted therein, examples are shown of a utensil 10-10c for cooking including a manipulator or extendable support 12-12c and a shield or shroud 14-14c that is movable between a first position and a second position relative to the manipulator 12-12c. Generally, the shield 14-14c is configured to be moved between a first position and a second position to selectively expose and surround a food-holding portion of the manipulator 12-12c, as discussed in greater detail below.
With reference to
In the illustrated example, the shaft 16 is cylindrical (
The manipulator 12 may include a handle 22 attached at the first end 18 of the shaft 16. In the illustrated example, the handle 22 is elongate and extends coaxially with the shaft 16 along the direction of the longitudinal axis A16. Accordingly, rotation of the handle 22 about the longitudinal axis A16 results in a corresponding rotation of the shaft 16 about the longitudinal axis A16. In the illustrated example, the handle 22 is substantially cylindrical in shape. However, in other examples, the handle 22 may be ergonomically formed to conform to a palm of a hand when the handle 22 is grasped. The handle 22 may be formed of an insulating material having a relatively low thermal conductivity, such as wood or a polymeric material or may comprise a metallic material (such as aluminum or the like) with a thermally insulating layer surrounding the metallic portion of the handle.

With continued reference to the example of the utensil 10 shown in
The shield 14 includes a shroud 28 and a sleeve 30 connected to the shroud 28. The shroud 28 is configured to at least partially surround the holder 24 when the shield 14 is in the extended second position, while the sleeve 30 is configured to provide a sliding interface between the shield 14 and the manipulator 12. The cross-sectional shape of the inner surface of the sleeve thus corresponds to the cross-sectional shape of the shaft (e.g., circular or polygonal).
In the illustrated example, the shroud 28 has a polygonal cross section relative to the longitudinal axis A16 of the shaft 16, and includes a plurality (such as four in the illustrated example) of sides 32a, 32b, 32c that are each configured to be spaced outwardly from the holder 24 by a predetermined distance when the shield 14 is in the second position. Particularly, the shroud 28 is rectangular-shaped and includes a first side 32a parallel to and spaced apart from a central plane P24 defined by the holder 24 (i.e., the plane extending through the two prongs 26). The shroud 28 further includes a second side 32b parallel to and spaced apart from the plane P24 of the holder 24 in an opposite direction from the first side 32a. The shroud 28 further includes an opposing pair of third sides 32c formed on opposite sides and each connecting the first side 32a to the second side 32b.
With reference to
Each of the perforations 34 is sized to suitably regulate thermal transfer through the first side 32a of the shroud 28. Here, a cross dimension of the perforations 34 ranges from 0.125 inches to 0.500 inches, but could be less than 0.125 inches. However, in other examples, different sizes of perforations 34 may be used to provide more or less exposure through the first side 32a of the shroud 28.
Referring now to
As best shown in
Alternatively, the sleeve 30 and the shaft 16 may be configured to limit rotation of the shield 14 relative to the manipulator 12. For example, where the shaft 16 is provided with a polygonal or irregular cross-sectional shape (
Thus, the utensil 10 comprises a shroud that is non-cylindrical or rectangular in shape so as to circumscribe a food item or items held at the holder end of the shaft. Parts of the shroud may have holes or perforations and/or parts of the shroud may not have holes or perforations. Optionally, the shroud may have different sized holes at different sides of the shroud to provide further options to the user for selectively heating the food item. For example, one side may have very small perforations, and another side may have larger perforations. For such applications where parts of the shroud has perforations of different sizes (and optionally with part of the shroud having no perforations), a user can rotate the shroud to provide the desired heating of the food item.

Optionally, the shroud 28a of the utensil 10a may include an end wall 32e facing the first end 18 of the shaft 16a (and optionally, the shroud 28, discussed above, may include such an end wall). The end wall 32e is transverse to the longitudinal axis A16 and connects the sleeve 30 to the sidewall 32d. Thus, instead of providing the shroud 28a with an open end having spokes 26 connecting the sleeve 30 to the shroud 28, the end of the shroud 28a may be substantially covered by the end wall 32e. As shown, the end wall 32e includes a plurality of the perforations 34 formed therethrough (but it could be a solid or non-perforated wall).
Thus, the shroud 28a comprises a cylindrical sheet of metal having perforations established therethrough in a desired pattern. Optionally, the shroud may have different sized or different spaced perforations at respective regions or portions of the cylindrical shroud. For example, one portion or region (e.g., a third or quarter of the shroud) may be non-perforated, another portion or region may have small perforations (e.g., having a cross dimension of around 0.125 inches or less), and another portion or region may have larger perforations (e.g., having a cross dimension of around 0.25 inches or more). Thus, the user of the utensil 10a may rotate the utensil and shroud so that the desired degree of perforations (e.g., no perforations, smaller perforations, larger perforations) is at the lower part of the shroud and directly over the flames, in order to provide the desired heating and cooking of the food item.

In this example, the sleeve 30 may include a grasp element 42 disposed at an opposite end of the sleeve 30 from the shield 14c. In other examples, the grasp element 42 may be disposed at an intermediate portion of the sleeve 30, or may be disposed adjacent to the shield 14. The grasp element 42 is formed of a thermally-insulating material, and allows a user to grab the sleeve 30 to easily move the shield 14c between the first position and the second position.
In use, the utensil 10-10c is configured to provide a thermal buffer between a heat source and a food item to allow the food item to be cooked in a regulated manner over an open and unregulated heat source adjusting the position and/or orientation of the shield 14-14c. As used herein, the term “thermal buffer” refers to the effect of the shroud 28-28c to dampen or regulate the transfer of heat between the heat source and the food item by absorbing and deflecting heat from the heat source. For example, the shroud 28-28c may absorb the thermal energy from the flame or heat source and provide a relatively consistent emission of thermal energy to the food. However, when flare-ups occur at the heat source, the shroud 28-28c may deflect a portion of the thermal energy of the heat source and maintain a relatively consistent temperature within the shroud 28-28c. Accordingly, cooking of the food within the shroud 28-28c can be more easily controlled.
As discussed above, the amount of the thermal buffer provided by the shroud 28-28c can be adjusted by changing the configuration, position, and/or orientation of the shroud 28-28c relative to the flame. For example, as discussed above with respect to the various utensils 10-10c, the shroud 28-28c may be provided with perforations 34 that are sized and arranged to provide a desired thermal buffer between the food and the heat source. Larger perforations 34 and or a greater concentration of perforations 34 will allow a greater percentage of the food to be exposed directly to the heat source through the shroud 28-28c. Conversely, forming the shroud 28-28c with smaller perforations 34, a lower concentration of perforations 34, or no perforations 34 will provide a greater thermal buffer between the heat source and the food (whereby the utensil may, when the shroud and food item are positioned over an open flame, provide heating of the food item in a manner similar to a convection oven, with no direct exposure of the food item to the flame). Optionally, the size of the perforations may be different at different sections or regions or walls of the shroud, such that different sized perforations may be selectively positioned at the flame by a user of the utensil to achieve the desired degree of cooking of the food item. Optionally, for non-perforated shrouds having no perforations, the shroud may function to heat the food item over an open flame with no exposure of the food item to the open flame, thus providing convection heating of the food item.
Additionally or alternatively, the shield 14-14c may be moved to the retracted first position (
Therefore, the utensil comprises a shield or shroud that comprises a cylindrical or non-cylindrical metal sheet (e.g., aluminum), optionally with part of the shroud having holes or perforations. The perforations may be different sizes at different portions of the shroud, and optionally at least one portion of the shroud is not perforated. The metal sheet or shroud provides a barrier between the food item and the open flame to limit or preclude direct exposure of the food item to the open flame when the shroud and food item are disposed at the open flame. For perforated shrouds (or parts of shrouds), the holes or perforations provide for ventilation of the chamber or space circumscribed by the shroud (where the food item is disposed) and may allow for some flames to enter the space, but substantially limit direct exposure of the food item to the open flames. The holes or perforations are a small portion of the overall surface area of the metal sheet or shroud, such that the perforations may be less than 20 percent, such as less than 10 percent or less than 5 percent of the overall cylindrical surface area (i.e., the metal sheet encompasses greater than 80 percent or greater than 90 percent or greater than 95 percent of an overall cylindrical surface that would be provided by the sheet if there were no perforations).
During use of the utensil, the user can rotate the shroud to provide the desired heating of the food item. Optionally, the shroud may have different sized holes at different sides or regions of the shroud to provide further options to the user for selectively heating the food item. For example, one side or region may have very small perforations, and another side or region may have larger perforations.
Optionally, the shield or shroud may be removably disposed at the shaft, such that different shaped shrouds or different perforated shrouds may be movably disposed at the shaft to adapt the utensil for cooking a particular type of food item. For example, a rectangular shroud may be replaced by a cylindrical shroud when cooking smaller food items, or a shroud having larger perforations may be replaced with a shroud having smaller perforations or no perforations, depending on the type of heating/cooking desired. For example, the rectangular shroud may be used for cooking the likes of hot dogs while the cylindrical shroud may be used for cooking the likes of marshmallows or other smaller food items or food items that are held longitudinally along the tines of the holder. The holder may detach from the end of the shaft to allow the shield to be removed or replaced, or the sleeve may be adaptable to allow for detachably attaching the sleeve along the shaft.
The utensil may be commercialized and sold as a kit having a shaft (having a handle and food holder or forked end) and two or more shields or shrouds, such that the user can select the desired shroud depending on the type or size of the food item to be cooked. The kit may include two or more shield assemblies, whereby the shield assembly (including the sleeve and shroud attached to the sleeve via brackets) is detachably disposed at the shaft and removable from the shaft to swap out the shield assembly for different shroud shapes and/or shroud perforations or the like. Optionally, the kit may include two or more shrouds, which are detachably attached at the sleeve via common or respective brackets, such that the sleeve remains on the shaft, but the user can replace the shroud to use different shroud shapes and/or shroud perforations or the like.

Individual elements or features of a particular configuration are generally not limited to that particular configuration, but, where applicable, are interchangeable and can be used in a selected configuration, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
