The present invention is directed to a device to lift, move and flip over foods.
Many devices are available today to lift, move and flip over foods. Among the most common are spatulas. Cooking tongs are also commonly found in kitchens and are used for lifting and flipping foods, particularly thicker foods such as steaks and hamburgers.
A device which offers significant improvements over both these earlier categories of food lifting and flipping devices is illustrated in U.S. Pat. Nos. 5,896,668, 5,813,120, 3,162,475, 4,734,984, 2,604,350, 1,202,120. The device is simply a transverse pointed hook on one end of a shaft. The opposite end of the shaft has a handle. By rotating this hook about the shaft axis, the user can pierce the food, and thereafter lift, move and/or flip the food over in a similar manner to that shown in
All kinds of foods may be lifted and flipped using this device including: meats, vegetables, fowl, hamburgers, fruits, breads, baked goods and much more. The device, however, has several shortcomings. First, the hook curves in only one direction. This favors right handed users to the disadvantage of left handed users or vise versa. This also means that it is easier to lift foods that are close to one side of a fry pan or other walled cooking vessel, verses foods that are close to the pan's or vessel's opposite side wall. The same is true when lifting foods from jars or other confined locations.
U.S. Design Pat. Des. 268,561 shows an artistic design improvement over earlier art with two hooks at the end of a shaft, each hook the mirror image of the other, and each hook being transverse to the shaft.
It would be helpful to have a device incorporating the ease of use and versatility of this hooked device with the versatility of a device which could be used easily by both right and left handed users as well as a device which could maneuver to pick up foods in all corners of pots and pans. Also, it might be helpful to have a device which would resist tearing of foods. Ease of construction to lower production costs would also benefit this category of device. As an example, it might reduce manufacturing costs if the device could be stamped from sheet stainless steel instead or requiring expensive welding and forming. Also, because these devices may be used near splattering hot grease and oil, as well as near burners and flame, means of protecting users from burns and getting dirty would be advantageous.
Shield 74 is illustrated with hinges 80, 82, 84 and 86, and bends 88 and 89 in its face. Shown in solid lines, the open position of shield 74 utilizes molded-in bends 88 and 89 to stiffen and open shield 74 when shielding is desired. When a more compact geometry is desired, such as when the fourth embodiment is being stored, the top and bottom of shield 74 may be folded back as shown in the dotted lines in
Shield 74 may be opaque, or as an alternate, may be, as illustrated in
Shaft extension pointed hook 98 is also illustrated in
All of the embodiments illustrated herein may also likely be used for other purposes. As examples, they may be used to push foods around in a fry pan, or stir foods in water or boiling water, or move foods in a wok, or flatten bacon in a fry pan, or pierce plastic packaging to ease opening, or scrape soilage off grills, or pierce foods to help spices and/or marinades penetrate the foods; or lift non-food objects such as cloth or paper or other things, or grab objects such as a fisherman grabbing a fish hooked on his line or a rope on a dock, or to help lift debris, or help grab trash from the ground or elsewhere, etc.
Also, features of each embodiment may be adapted to fit other embodiments. As examples, hooks 42, 44, 68, 70, 72, 90 and 92 shown in the figures may be done by stamping the design from sheet material as suggested in the second and third embodiments. This might result in the hooks being generally rectangular in cross-section. Likewise, shield 74 and shield 100 might each be interchanged with the other, or might be each individually adapted to fit onto any of the other embodiments. Or bent hooks 90 and 92 might replace any of the arcuate hooks; or any of the handles shown on the embodiments might be interchanged, etc.
The sixth embodiment shows elliptical handle 136 which may provide, when compared to a cylindrical handle, tactile orientation for the embodiment as well as a comfortable grip with good leverage for lifting and flipping articles.
Referring to
On the opposite end of handle 200 from cap 216 is shield mount 220 which removeably mounts polygonal shield 204. Extending from the forward 226 end of shield mount 220 is shaft support 224 which securely holds shaft 222 and rigidly attaches it to handle 200. On the opposite end of shaft 222 from shaft support 224 is tapered portion 225 of shaft 222. Generally, shaft 222 is consistently cylindrical except for tapered portion 225.
Tapered portion 225 on the forward 226 end of shaft 222 firmly attaches hooks 206 and 208 to shaft 222.
Referring to
When resting on a countertop or other surface, flats 232 (seen on
In use, the embodiment may be stored in a drawer or cabinet or other suitable location, or it may be hung perhaps using hole 218 in handle cap 216 either directly such as on a post or nail or the like; or using a string or other filament secured through hole 213. Shield 204 may be removed for compactness or other purposes during storage, or it may be left on.
Referring to
As shown in
Each of these eight positions corresponds to one of the eight flats 232 on the periphery of shield 204 resulting in flats 232 of shield 204 always having a specific predictable radial relationship between flats 232 and hooks 206 and 208 no matter how the user mounts shield 204. This predictability may make it easier to use the refined embodiment. As shown in
Mounting shield 204 is accomplished by the user sliding shield 204 between rear flange 234 and forward flange 232 as shown in
Shield 204 may protect user from heat, hot oil, hot water, hazardous chemicals, or other materials and/or conditions. The embodiment may be used with or without shield 204 mounted. Shield 204 may be constructed in any of many different materials and using any of many different manufacturing processes. As examples; shield 204 may be constructed of clear, natural or pigmented: polypropylene, polyethylene, ABS, acrylic, nylon, SAN, PBT other plastic; or stainless steel, steel, aluminum, or other metal, or ceramic, or other material. It may be manufactured by: injection molding, stamping, laser cutting or other manufacturing process.
For example, injection molding shield 204 from clear polypropylene may have several advantages which may include one or more of the following: low cost (due to inexpensive production methods, low material costs and fast molding cycle times), high production rates, relatively inexpensive tooling, resistance to grease, oil, other chemicals and detergents, high and low temperature resistance, long material life, dishwasher safe, translucence, simple and low cost to mold in other features such as graphics, text, clips brackets etc.
Hooks 206 and 208 are essentially circular arcs as demonstrated by dotted line circle 264 in
Angle 266 is measured in side view
When angle 266 is less than 54 degrees food or other artless tend to unscrew off the hook particularly when used in jars and deep pans. When angle 266 is greater than 76 degrees the point where hooks 206 and 208 meet shaft 222 tends to protrude and interfere with foods and other articles being hooked. Similarly, when angle 214 is less than 123 degrees, it tends to let food and other articles slip off of hooks 206 and 208 particularly when shaft 222 is in a more vertical position. And when angle 214 is greater than 147 degrees it becomes more difficult to hook foods and other articles because the joint between hooks 206 and 208 and shaft 222, bumps against the foods or articles before they are fully engaged with hooks 206 or 208.
Angle 254 in top view
The dimension from tip of hook 206 to the tip of hook 208 has been found to be particularly important in achieving generally comfortable and easy use of the embodiment. On embodiments that will be used in a home kitchen, a distance between 1⅜ and 1¾ inches between the tip of hook 206 and the tip of hook 208 has been found to be particularly convenient for use with fry pans of 7 to 14 inches in diameter, and in common jars, and with Tupperware® type containers, and with 6 to 10 inch diameter pots, as well as with other common kitchen items. Smaller hooks tend to provide insufficient grip on common articles, and larger hooks tend to be too clumsy within or around the above items.
In commercial kitchens and for outdoor barbeques, a distance between 2¼ inches and 2¾ inches from the tip of hook 206 to the tip of hook 208 has been found best for general use. This is because pots and pans and storage containers and other items used in these environments tend to be larger than those used in home kitchens, and also because food items handled may also be larger. Space in general in these environments tends to be less cramped than in home kitchens.
Engaging food and other articles by rotating the refined embodiment clockwise 260 or counterclockwise 262 using the same hand without repositioning the hand, may be one of the advantages of using the embodiment. Likewise, using the embodiment in either a user's left or right hand can be yet another advantage. Also, being able to use the embodiment in confined situations such as near or against the left or right side of a pan or near or against the left or right side of a jar is yet another advantage.
As shown in
Although the handle may be constructed at any size, a length of 3½ inches to 4¾ inches has been found to be particularly advantageous for both users with relatively small and large hands. Likewise, a handle elliptical cross section having a minor axis dimension between ½ inch and ¾ inch and having a major axis dimension between ⅝ inch and one inch has also been found to be particularly useful in providing users with both relatively small and large hands with an effective and comfortable grip.
Three particular lengths have been found particularly useful in fabricating the embodiment. For an embodiment used in home kitchens with pots, pans, jars, stove top grills, fry pans, countertop grills, plastic storage ware, sinks, storage bins, etc., a length of between 9 and 11 inches measured from where shaft 222 exits shaft support 224 to the tip of hook 206 has been found exceptionally convenient. For an embodiment used in commercial kitchens with larger pots, pans, jars, grills, fry pans, plastic storage containers, sinks, storage bins, etc., a length of between 15 and 17 inches measured from where shaft 222 exits shaft support 224 to the tip of hook 206 has likewise been found exceptionally convenient. And finally, for an embodiment used with outdoor barbeques, a length of between 20 and 22 inches measured from where shaft 222 exits shaft support 224 to the tip of hook 206 has similarly been found exceptionally convenient.
The ends of hooks 206 and 208 are sharp to facilitate penetrating meats, vegetables and other materials. To prevent possible accidental injuries, a protective cover to shield the ends of hooks 206 and 208 may be used. Many designs may provide effective protection including pockets or envelopes to cover the hook ends or tubes which might cover the entire hook end of the refined embodiment.
One design which may provide both relatively easy use and good protection is shown in
Guard 268 may be left at all times on shaft 222 including during use and storage, or it may be removed for any reason. Using guard 268 when it is attached to shaft 222 simply entails sliding guard 268 between retracted position 270 when not in use, to protective position 272 to cover the tips of hooks 206 and 208.
Finger grip 277 helps provide a grip for retracting guard 268 from protective position 272 to retracted position 270.
One skilled in the art would readily recognize that many variations from, and alternatives to, the above could be made and still utilize the present inventions. As just a few illustrative examples: shield 204 may have fewer or more than 8 flats on its periphery and they may be regular as in a pentagon, hexagon or square etc. or they may be irregular or even have curves or voids or concave or convex sections between flats on the shield periphery; the engagement between shield 204 may rely on something other than a snap fit with fixed radial resting points such as a friction fit between shield 204 and front flange 232 and rear flange 234 (a fit relying primarily on friction) or a friction fit between shield 204 and core 236, or a snap fit between shield 204 and front flange 232 and rear flange 234, or shield 204 might slide over core 236 with core 236 being hexagonal, octagonal or other shape rather than gear shaped; There may be more than hooks 206 and 208 at the end of shaft 222 such as was suggested in the antecedent to this application; dimensions other than those suggested herein may be advantageously used, particularly where a more focused and less general use is intended such as shaft 222 having a length of less than 9 inches and a distance of less than 1⅜ inches between the tips of hooks 206 and 208 in a device intended exclusively or primarily for removing items from jars; there may be a hook or hole 218 combined with a hook or detent or other device on the end of handle 200 to hang or store the embodiment; handle 200 might be round or square or triangular or other shape in cross section, or might be tear shaped, spherical, or other shape in general; shaft 222 might be elliptical, square, triangular, polygonal or irregular in cross section; the embodiment might be used for other purposes such as picking up trash or harvesting fruits from tree limbs or material handling in factories etc.; materials and fabrication methods other than those suggested might be used such as laying up shaft 222 out of carbon fiber composites or compression molding handle 200 from a thermo set resin; etc.
Embodiments incorporating the present inventions may be constructed at any scale and from a variety of materials. As examples, embodiments from six to twenty-four inches in length may be constructed with shorted lengths useful in home kitchens with typical home range tops. Longer lengths might be used for outdoor barbecuing where there is more heat and more possibility of getting burnt or injured and where food items may be larger. Even larger versions still, such as twenty-four to thirty-six inches in length, might be used for picking up debris or use while fishing.
Materials used in construction may likewise vary widely. As examples, stainless steel or ceramics or composites or plastic or wood might be used to form some or all of the embodiments.
What is described and illustrated herein are preferred embodiments of the present inventions. Many variations of, alternatives to, and/or modifications of these embodiments, which incorporate some or all of the present inventions, will be obvious to those knowledgeable of the art. Thus the scope of patent protection afforded the present inventions shall thus solely be determined by the issued claims this specification is allowed as well as their legal equivalents, and not restricted by the limited descriptions of preferred embodiments contained herein.
