BACKGROUND
The present invention relates to an adjustable bundling device for holding together one or more items and to the method of making and using the adjustable bundling device.
Bundling devices, also known as cinching devices or trussing devices, facilitate cinching, bundling, rolling, stuffing, securing, holding and the like, of edible items, e.g. meats, fish, fruits and vegetables, as well as other items.
Since ancient times, cooking certain items has presented challenges. Items that tend to break apart during the cooking process present one of those challenges, such as poultry that is baked in the oven. One solution for poultry pertains to using a truss.
To truss means to secure poultry or meat into a compact shape. To truss poultry with string, you take a piece of butcher's string about three times the length of the bird, places the bird on its back, with the tail end nearest to you. You then slide the string underneath so that it is cradling the bird in the center of its back. You then gently pull the string up the sides, then around the wings of the bird. Pull the strings toward you, close to the breast of the bird, so that the wings are held against the body of the bird. Cross the strings at the base of the breast of the bird; then wrap each string around the end of a drumstick. Tie the ends of the string together, cinching it tightly so that the legs cross. Then lift the bird so that the tail end is up and wrap the string around the tail. Tie the string, pulling tightly so that the cavity is covered by the tail. Place the bird on its back again and bring the string back to the front, then tie it off. The bird is now ready for the oven. This is a complicated and time-consuming process.
Previous attempts to simplify this process and to provide for trussing poultry, for example, include the following. U.S. Pat. No. 5,380,241, issued to Volk, teaches using a one piece and substantially coplanar thin plastic member. U.S. Pat. No. 3,877,109, issued to Moncrief, teaches a fowl spit roasting holder of bent bar with neck loop and leg and wing restraining sections.
Prior solutions to holding food, such as shown by the Sydlosky patent, U.S. Pat. No. 6,394,305, have been used to provide a way to hold food while transporting it from the baking pan to the carving area. Such provision for holding food is achieved by having the holding device placed underneath and on a plurality of sides of the food, e.g. a baking turkey, prior to the baking process, so that the food could be removed intact.
Another cooking challenge is the cooking of small items, especially on a grill. The problem with cooking small bits of food is that the food is hard to handle and the fire can easily burn a person's arms and hands if the person gets too close to the fire. Holding items together, such as food for cooking, has traditionally been accomplished by using string, toothpicks, skewers, large needles with thread, aluminum foil, and the like.
U.S. Pat. No. 2,935,013 to Onori discloses a skewer. Skewers of various designs are attempts to solve this challenge by mounting the food thereon so that it could all be handled at one time. The skewer also provides a handle which can be kept away from the fire so that the hand is not subject to getting burnt.
There are problems with these attempts to hold food for cooking. Using aluminum foil can contaminate the food and may scratch a Teflon coated pan. String and toothpicks may burn at the high cooking temperatures. Aluminum foil, string and toothpicks are generally not reusable. Using string, toothpicks or aluminum foil generally requires more than one hand. Sharp skewers or needles can be dangerous
While these patents and other previous methods have attempted to solve the problem of holding food during the preparation and cooking process, none have employed a device that cinches and is reusable.
Therefore, a need exists for an improved holding device that can cinch instead of tying, be reusable, engage and disengage faster than conventional methods, utilize fewer hands in its operation, will not scratch Teflon coated pan, and will not burn below intermittent temperature of 850° F. and 750° F. sustained.
The foregoing patent and other information reflect the state of the art of which the inventor is aware and are tendered with a view toward discharging the inventor's acknowledged duty of candor in disclosing information that may be pertinent to the patentability of the present invention. It is respectfully stipulated, however, that the foregoing patent and other information do not teach or render obvious, singly or when considered in combination, the inventor's claimed invention.
SUMMARY
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new device and method for effectively and efficiently holding items, such as, but not limited to, food. The present invention is intended to be used over and over again for cinching, bundling, rolling, stuffing, securing, holding and the like.
The main area of application for the present invention is for food items, e.g. meats, fish, fruits and vegetables. However, the present invention can also be used for the holding of most anything. In the kitchen or on the grill, the present invention replaces the need for the tying of kitchen twine, piercing with toothpicks or use of aluminum foil to hold stuffed foods.
One objective of the present invention is to provide an adjustable bundling device that will cinch one or more items together.
Another objective of the present invention is to provide an adjustable bundling device that is inexpensive.
Another objective of the present invention is to provide an adjustable bundling device that is easy to use.
Another objective of the present invention is to provide an adjustable bundling device that can be reused many times.
Another objective of the present invention is to provide an adjustable bundling device that is dishwasher safe.
Another object of this invention is to provide an adjustable bundling device which uses simple materials and components.
Another objective of the present invention is to provide an adjustable bundling device that adjusts for engaging a wide range of items.
Another objective of the present invention is to provide an adjustable bundling device with releasable locking in the desired position after engaging the desired item.
Another object of the present invention to create an adjustable bundling device operable for quick and easy clenching.
It a further object of the present invention to provide an adjustable bundling device that is easily reusable and washable.
It is yet another object of the present invention to provide an adjustable bundling device operable to allow for the easy tightening and loosening of items within the adjustable bundling device.
The present invention is comprised of a flexible cord portion, a sliding, tensioning portion operable for slideable, releasable locking, and an end portion. These portions are made of plastic, metal or other suitable material that retain their functionality and form at high temperatures, e.g. cooking.
The present in invention can be described as a tool or device that performs the function of holding, bundling, cinching, tying, rolling, securing, stuffing and the like in such environments as in the kitchen, the office, around the home, in the car, at work, at play, camping and the like. The unique method by which this tool performs is by way of a specially designed cavity that corresponds to a length of material described as a cord which, with applied finger pressure on said cord while holding the part known as the cavity, the two parts can then be forced together. The cord is attached to the cavity on one end and will fit into the cavity along its length. Depending on the direction in which the cord is inserted into the cavity will determine if the tool makes a noose shape or a loop shape. This shape can be pulled from the opposite of the cavity end to close the shape down tighter or be pushed through the cavity to open up the shape larger.
The size of the cavity in relation to the size of the cording is important due to the coefficient of friction that exists between the two sections. This can be expressed in percentages. The percentage the cavity section can be larger than the cord section is 10%. 0% would mean the cavity section and the cord section are the same diameter. The percentage smaller that the cavity section can be from the cord section is 40%. The durometer of the flexible compound is also a factor in the performance of the present invention. The more flexible the compound the smaller the cavity can be. The more rigid the material is the closer in size the cavity and the cord must be. This can also be described in terms of a percentage on the shore hardness A scale.
Another contributing factor that is necessary for the present invention's performance can be described as the amount of slippage or tacticity that is compounded into the flexible material. This is directly proportionate to the durometer of material formulation. The compound that makes the present invention work for food is a specially formulated and cross linked using FDA approved silicone blends that give the properties of High Temperature resistancy up to 750 degrees Fahrenheit sustained, and 850 degrees Fahrenheit intermittent. The formula for the compound will be retained as a trade secret.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto. In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings.

In the preferred embodiment the adjustable bundling device is comprised of textured cord 30, cavity end 20 and stop 40.
In the preferred embodiment the adjustable bundling device is typically manufactured from a specific type of heat-resistant silicon. A two-part mold cavity of the geometry is created using industry standard methods and silicon is poured into a mold cavity. The mold is then opened and the adjustable bundling device removed. In the preferred embodiment, textured cord 30, cavity end 20 and stop 40 are all made from the same heat-resistant silicon. However other materials, e.g., stainless aircraft cable, cast stainless steel, other types of silicon, rubber or other material combinations, can be used.
FIG. 2 through FIG. 6 and FIG. 9 show how a portion of textured cord 30 can be inserted into cavity end 20. Textured cord 30 is operable to enter and exit cavity end 20 in a direction normal to the axial length of textured cord 30 as shown in FIG. 4.
Cavity end 20 is preferably permanently attached at one end of textured cord 30 in such a way that another section of textured cord 30 can be ‘looped’ and routed into cavity end 20 as shown in FIG. 5 and FIG. 6. Textured cord 30 is of a length relative to the size of cavity end 20 that looping or noosing of textured cord 30 is possible. In the preferred embodiment, textured cord 30 length is approximately 14 inches. After textured cord 30 physically enters into interior cavity 26, textured cord 30 is held in place relative until the user removes it with moderate force. Additionally, textured cord 30 device can be axially pulled through interior cavity 26 of cavity end 20 to increase and decrease the size of the ‘loop’ formed as shown in FIG. 5 and FIG. 6. Additionally, stop 40 prevents the cord from passing out of the interior cavity 26 axially.
The common use of the preferred embodiment of an adjustable bundling device is as follows. Take the adjustable bundling device and lay it on a flat surface with interior cavity 26 facing down and place object 10 to be wrapped or cinched in the center of the adjustable bundling device as shown in FIG. 2. Lift cavity end 20 and stop 40 in the direction of the arrows and curve around object 10 with textured cord 30 as shown in FIG. 3. Continue to bring cavity end 20 and stop 40 together until they meet as shown in FIG. 4. Press with thumb and forefingers in the direction of the arrows to insert texture cord 30 into the cavity 26. Pressing textured cord 30 against cavity end 20 opens flexible edge-a 22a and flexible edge-b 22b of interior cavity 26 in such a way that it releases back cord lock-a 23a, back cord lock-b 23b, front cord lock-a 24a, and front cord lock-b 24b due to the mechanical linking of the material as shown in FIG. 7. Once textured cord 30 is within interior cavity 26, back cord lock-a 23a and front cord lock-a 24a keep textured cord 30 from slipping out the top of interior cavity 26 as shown in FIG. 9. Textured cord 30 is guided out of the front and end of the interior cavity 26 with front cord guide 27 and back cord guide 29.
To tighten the loop, grip cavity end 20 and stop 40 and pull in the direction of the arrows as shown in FIG. 5. As the cord is moved through the cavity, cord indentions 31 in textured cord 30, and mating protrusion-a 21a and mating protrusion-b 21b in cavity end 20 intersect and mesh, creating a tactile click and locking the cord into place laterally, allowing the adjustable bundling device to tighten as shown in FIG. 6 and stay in position. Additionally, finger grip 25, and raised branding area 41 facilitate a positive grip for the user.
The physical principles used to lock the cord into cinching position include friction of cord against the cavity walls, partial encasement of the cord, indentions in the flexible cord combined with protrusions in the interior of the cavity end, particular flexing of the cavity end for sliding, and particular flexing of the cavity end for insertion
Along the entire length of interior cavity 26 textured cord 30 is interference fit. Because cavity end 20 is typically more flexible than textured cord 30, cavity end 20 deflects to allow textured cord 30 to enter. Inserting textured cord 30 deforms cavity end 20. Spring-back of the material of cavity end 20 forces the sidewalls of interior cavity 26 against textured cord 30 as shown in FIG. 9. Friction acts along the entire inside surface of the interior cavity 26 where it interfaces with textured cord 30. This friction acts to prevent axial sliding of textured cord 30 along interior cavity 26.
The cord is also retained within in the cavity by a function of partial encasement and particular flexing of the cavity as shown in FIG. 9. When the cord is forced through the opening of the cavity as in FIG. 4 with force in the direction of the arrows, the cavity flexes at flexible edge-a 22a and flexible edge-b 22b to allow the cord to enter. When flexible edge-a 22a and flexible edge-b 22b are pushed open by the cord, locking features at the beginning of cavity end 20, i.e., front cord lock-a 24a and front cord lock-b 24b, and at the end of cavity end 20, i.e., back cord lock-a 23a, back cord lock-b 23b, open, allowing textured cord 30 to slide in place in the cavity. After entering, flexible edge-a 22a and flexible edge-b 22b reform around the cord as shown in FIG. 9, keeping textured cord 30 locked into interior cavity 26 until textured cord 30 is forcibly removed. Thickened sections at the beginning of interior cavity 26, i.e. front cord lock-a 24a and front cord lock-b 24b and end of interior cavity 26, i.e., back cord lock-a 23a and back cord lock-b 23b serve as locking features to retain textured cord 30 in interior cavity 26.
To keep textured cord 30 from siding within interior cavity 26, indentions in textured cord 31 and mating protrusion-in interior cavity 26 interact and mesh. The mating protrusion-a 21a and mating protrusion-b 21b are shown in FIG. 8. When textured cord 30 is slid down interior cavity 26 axially, mating protrusions and indentions act as a series of stops, allowing the loop or noose to be changed in size, tightened around one or more objects, or loosened to release one or more objects.
The second preferred embodiment of an adjustable bundling device is shown in FIG. 10 through FIG. 21. This embodiment operates similarly to the adjustable bundling device shown in FIG. 1 through FIG. 9 but is preferably created out of stainless steel instead of a silicon blend. The actions in FIG. 2 through FIG. 6 are identical using this embodiment to cinch around an object.
To create this embodiment of an adjustable bundling device, a slide form tool is used to form cavity end 130 separately as shown in FIG. 17 through FIG. 19. A stamping tool is created and used to form stop end 110 out of stainless steel which is formed and permanently attached to textured cord 120. Cavity end 130 and stop end 110 are preferably approximately 1″ in length, 0.5″ wide and 0.5″ deep. Textured cord 120 is preferably 0.0625″ diameter of spirally wound stainless steel aircraft cable. The free end of textured cord 120 is placed through bottom cord area 141 of inner cavity 142 in the manner shown in FIG. 11 through FIG. 13. Textured cord 120 is then welded in bottom weld area 133 and front weld area 140 as shown in FIG. 16 to secure textured cord 120 to cavity end 130.
The functional attributes differ slightly from the preferred embodiment shown in FIG. 1 through FIG. 10. In order to secure textured cord 120 into cavity end 130, textured cord 120 is placed against and between lock lip-a 136a and lock lip-b 136b of cavity end 130 as shown in FIG. 20 and FIG. 21. Textured cord 120 is then pressed into cavity 130 using thumb and forefinger.
Pressing textured cord 120 drives cavity end 130 open, flexing back upper hinge-a 143a and back upper hinge-b 143b as shown in FIG. 21, allowing textured cord 120 to penetrate the inner cavity and flex lower curve hinge-a 138a and lower curve hinge-b 138b. Back upper hinge-a 143a and back upper hinge-b 143b have a wider initial gap than front upper hinge-a 144a and front-upper hinge-b 144b. The difference is that the initial gap allows the cord to be inserted easier in the back section than in the front section. As textured cord 120 enters from the back of the cavity and proceeds to enter the front of the cavity, it spreads the front upper hinges allowing the cord to fit within the entirety of inner cavity 142. These front and back upper hinges are an integral part of the same hinge structure; it helps to explain the function to separate them into front and back elements.
At this point, textured cord 120 presses towards locking protrusions 135a, 135b, 135c, 135d, 135e, 135f, curve hinge-a 138a and curve hinge-b 138b flex, locking protrusions 135a, 135b, 135c, 135d, 135e, 135f move away from textured cord 120, and textured cord 120 drops past the locking protrusions 135a, 135b, 135c, 135d, 135e 135f and into inner cavity 142. Spring-back of cavity end 130, preferably made from stainless steel, attempts to return cavity end 130 to its original shape and causes friction along the entire length of bottom cord area 141 which acts to hold textured cord 120 in place.
To slide textured cord 120 within bottom cord area 141 to tighten objects with this embodiment of the adjustable bundling device, hold cavity end 130 by fingergrips 131a, 131b, 131c, 131d, 131f with thumb and forefinger against outer wall 139 or front wall-a 137a and front wall-b 137b and pull textured cord 120 and stop end 110 until the cord loop is sufficiently decreased in diameter to clench/cinch the object desired.
The cord is held in place along inner cavity 142 by spiral stop 134. Spiral stop 134 acts on the spiral wrapping of textured cord 120, which is preferably made of aircraft cable. Additionally, spiral stop 134 provides both auditory and tactile feedback as spiral stop 134 moves in and out of the texture of the cord causing curve hinge-a 138a and curve hinge-b 138b to flex.
The third preferred embodiment of this invention is shown in FIG. 22 through FIG. 31. This embodiment operates similarly to the previous two with respect to clenching objects and therefore utilizes the same actions to clench items, e.g. food, as in FIG. 2 through FIG. 6. The locking mechanism in this embodiment has a few different functional elements.
To create the third embodiment of an adjustable bundling device, an injection molding cavity is used to create the device that is shown in FIG. 22. Cord 210 and cavity end 220 are attached as shown. The preferred material is a proprietary high-temperature thermoplastic. This embodiment uses a much stiffer plastic than the previous embodiments. Cord 210 has a plurality of spherical protrusions 211a, 211b, 211c along the length of cord 210. Connecting these spherical protrusions are short cylinders 212a, 212b, and 212c dimensioned to be of a smaller diameter than the spheres.
Referring FIGS. 23 and 24, a close up view of cavity end 220 is shown. Inner cavity 222 helps guide cord 210. Outside protrusions 221a, 221b, 221c, 221d, 221f act as finger grips as this embodiment of the adjustable bundling device is often used with greasy or wet objects. Cavity lip-a 225a and cavity lip-b 225b act on short cylinders 212a, 212b, 212c of cord 210, and the slot that is formed is slightly narrower than the cylinders. Spherical cut 223 acts on spherical protrusions 212a, 212b, 212c on cord 210 since spherical cut 223 is of a slightly smaller diameter than spherical protrusions 212a, 212b, 212c. Sloped lip sections-a 226a and sloped lip section-b 226b act to guide cord 210 into inner cavity 222 and help align cord 210 so it may be pressed into inner cavity 222. Inner protrusions 224a, 224b, 224c, 224d, 224e, 224f, 224h help lock spherical protrusions 212a, 212b, 212c and cord 210 in place axially after cord 210 is placed into the cavity.
FIG. 25, FIG. 26 and FIG.-27 show cord 210 in inner cavity 222. Spherical protrusion 211g is of slightly larger diameter than the spherical cut 223, requiring the user to insert cord 210 into inner cavity 222 with force to overcome friction and mechanical resistance. Additionally, cavity lip-a 225a and cavity lip-b 225b form an opening slightly smaller than short cylinder-g 212g and short cylinder-h 212h, requiring finger force from the user to insert the cord into the cavity.
To insert cord 210 into cavity end 220, place cord 210 over the cavity lips as shown in FIG. 28 and FIG. 29. Align spherical protrusion 211g over spherical cut 221 using the mating shapes as tactile guidance. When these are aligned, press cord 210 into inner cavity 222 using thumb and forefingers. The mechanical friction will make insertion difficult, but will keep the two parts from coming undone until removal is desired.
In order to increase or decrease the degree of clenching of this embodiment of an adjustable bundling device, slide cord 210 axially along inner cavity 222. An additional mechanism is used in this embodiment to keep the adjustable bundling device axially locked as shown in FIG. 30 and FIG.-31. Internal protrusions 224a, 224b, 224c, 224d, 224e, 224f, 224h mate and engage with spherical protrusions 211a, 211b, 211c, 211d, 211e, 211f, 211g as cord 210 is slid up and down inner cavity 222 locking cord 210 in place axially.
The fourth preferred embodiment of the present invention is shown in FIG. 32 through FIG. 42. This embodiment operates similarly to the previous three with respect to clenching objects and therefore utilizes similar actions to clench food as shown in FIG. 2 through FIG. 6. The locking mechanism in this embodiment has a few different functional elements.
To create this embodiment, an injection molding cavity is used to create the adjustable bundling device as shown in FIG. 40 through FIG. 42. The material used is a stiff plastic, e.g., Nylon. The thickness of the plastic wall is preferably approximately 0.020 inches. The same process is used to create this embodiment as is shown in FIG. 1.
First, small hole-a 311a and small hole-b 311b (not shown) are formed in cavity end 310 as shown in FIG. 33. These small hole-a 311a and small hole-b 311b mate with pivot protrusion-a 334a and pivot protrusion-b 334b in cap 330. Textured cord 320 is used as described in the first embodiment. Other than cap 330, this embodiment has identical functionality of the first embodiment.
Linkage-a 335a and linkage-b 335b link the locking elements of cap 330 with the pivot protrusion-a 334a and pivot protrusion-b 334b. The length of these linkages is such that stop end 350 can pass through with minimal difficulty as shown in FIG. 34.
FIG. 34 through FIG. 37 show how cap 330 is secured around cavity end 310. In FIG. 37 and FIG. 38, fang-a 340a and fang-b 340b are shown mating with cord cutout-a 321a. Fang-a 340a and fang-b 340b wrap around the cord cutouts as shown in FIG. 38, both locking cap 330 down around cavity end 310 and preventing textured cord 320 from sliding axially within cavity end 310. Fang bar 338 holds fang-a 340a and fang-b 340b in place and also holds the left and right side of cap 330 together.
In FIG. 37 and FIG. 39, mating protrusion 336 is shown mating with cord cutout 321b. The intersection of these two elements helps prevent textured cord 320 from sliding axially within cavity end 310. Mating protrusion 336 is held in place by mating bar 337, which also holds the left and right sides of cap 330 together.
An additional method of keeping cap 330 locked is shown in FIG. 38 through FIG. 42. Side bar-a 333a and side bar-b 333b press into the flexible material of cavity end 310. Using the friction and the spring back properties of both cap 330 and flexibility of cavity end 310, assists in the locking of cap 330 into place.
An additional method of keeping cap 330 locked is shown in FIG. 37 through FIG. 42. First finger grip-a 312a and first finger grip-b 312b and second finger grip a 313a and second finger grip-b 313b are used as a locking device when finger grip cutout full-a 331a and finger grip cutout full-b 331b and finger grip cutout partial-a 332a and finger grip cutout partial-b 332b are placed around them. This is shown in FIG. 38 in the cross-section view as 312b and side bar-b 333b, as well as 312a and side bar-a 333a fit tightly around each other. Using friction and spring back properties of both cap 330 and the flexibility of cavity end 310, helps to lock cap 330 into place.
In order to unlock cap 330 from cavity end 310, finger bar-a 339a and finger bar-b 339b are used. These elements allow the user a way to pull the cap off of the adjustable bundling device so whatever it is holding can be un-cinched.
