The field of the invention is mixing bowls for use in a kitchen. Specifically, the field of the invention is a mixing bowl assembly that has a base suction device that can be securely mounted to a counter or work surface and a bowl suction device that holds the bowl at any angle desired by the person using the bowl.
Mixing bowls are commonly used to mix food ingredients as part of the cooking process. Ingredients may be mixed before they are placed in a cooking pan for baking or before they are placed in a serving dish and served for consumption.
Some ingredients, such as liquids, are relatively easy to mix, while others, such as cold or chunky foods, are more difficult to mix. Other ingredients must be added gradually while mixing is in progress. An example is flour, which must frequently be added gradually to a relatively smaller amount of liquid, such as milk, and other ingredients such as sugar or butter.
When different types of food are mixed, it is often necessary to position the bowl to better accommodate the ingredient being added. For example, sifting flour usually requires an upright bowl, whereas, beating an egg is more easily done in an angled bowl. If the bowl must be angled, either to accommodate the type of ingredient being added or for the comfort of the person who is doing the mixing, the cook must hold the bowl in one hand at the desired angle and mix with the other hand.
Further, if an ingredient must be added as mixing is taking place, it is often necessary to angle the bowl with one hand to properly or comfortably add the ingredient to the mix with the other hand. Then, while either keeping a grip on the bowl or changing the bowl angle with the hand gripping the bowl, the cook must, with the other hand, place the container on the work surface and pick up the mixing spoon or electric mixer to continue the mixing process.
If the person who is doing the mixing does not keep a grip on the bowl during the mixing process, the bowl may be at an inappropriate angle for effective mixing, or the bowl may tip or move during mixing. Similarly, if the mixing process is done with the bowl at an inappropriate angle, the contents of the bowl may spill, splash, or otherwise be ejected from the bowl during the mixing process. Such spills are common when liquids or ingredients of different sizes or different liquid/solid consistency are being mixed. Similarly, if one must mix ingredients vigorously—e.g., an egg or cream until stiff—it is especially important to keep the bowl steady and at the proper angle, lest the contents are spilled or the mixing does not allow the ingredient to reach the desired constancy as a result of the mixing.
Prior art bowls have used various devices or structures to attempt to solve, or at least ease, these problems for the cook. For example, Tardiff U.S. Pat. No. 5,423,452 shows gripping treads or lugs on the bottom of the bowl. Morris U.S. Pat. Nos. 5,634,617 and 5,813,638, show the use of a stand for the bowl. Lauer et al U.S. Pat. No. 6,688,485 shows a bowl tilted in a base. Tieffel et al. U.S. Pat. No. D364,546 shows a bowl stand with attachers at the top of the stand. And, Heiberg et al, U.S. Pat. No. 5,169,023 shows spaced ribs on the side of the bowl.
Devices or structures such as those shown in the prior art tend to resist movement of the bowl on the work surface or make it easier to keep the bowl at certain angle. However, even these devices and structures require hand control by the person doing the mixing and are frequently unstable both on the stand or base on which they are set and at the angle at which the bowl is to be kept. None of them show a secure attachment of the base or bowl to the work surface. Only Tieffel shows a means for secure attachment of the bowl to the base. None of these prior art devices or structures discloses a secure, firm attachment of both the bowl to the base and the base to the work surface. Thus, these prior art devices merely mitigate the difficulties associated with mixing and mixing bowls. They do not substantially resolve solve those difficulties.
The mixing bowl assembly of the invention has comprises a base and a bowl. The bottom of the bowl is rounded and generally hemispherical.
The base comprises a lower portion, an upper portion, at least one side, a bottom, a top, an interior chamber, a top opening, and a bottom opening. The side or sides of the base also form elongated horizontal slots, one below the top opening of the base and the other above the bottom opening of the base. The bottom of the base is substantially flat. The top of the base is concave and is shaped to receive the rounded or hemispherical bottom of the bowl.
The interior chamber houses two suction devices—i.e., a counter suction device and a bowl suction device. The counter suction device is associated with and operated through the opening in the bottom of the base. The bowl suction device is associated with and operates through the opening in the top of the base.
The counter suction device comprises a suction pad, a suction pad plate, a handle, and a pivot. Two spaced-apart bridge-like structures extend away from a side of the plate. Each bridge-like structure has an underside that is ramped or sloped. The pivot is situated between the bridge-like structures. The handle extends from the underside of one of the bridge-like structures, through the pivot, along the underside of the other bridge-like structure, and outward thorough the elongated slot above the bottom opening of the base. The handle, so situated, is in sliding contact with the sloped undersides of the bridge-like structures. The suction pad is attached to the side of the plate from which the bridge-like structures extend; however, the suction pad is larger than the plate and extends outward from and beyond the perimeter or circumference of the plate. The counter suction device is oriented so that the part of the suction pad that extends outward from the plate makes contact with the counter or work surface through the bottom opening of the base.
The bowl suction device is constructed substantially the same as the counter suction device. However, the bowl suction device and its suction pad are oriented in the chamber of the base such that the part of the suction pad that extends outward from the plate makes contact with the hemispherical or rounded bottom of the bowl through the top opening of the base. The handle of the bowl suction device extends outward thorough the elongated slot below the top opening of the base.
The suction devices are described in additional detail in the co-pending application of inventors Charles S. Paradise and Louis F. Henry.
Each suction device is operated by moving its handle from one side of its elongated slot to the other. Movement of the handle in one direction causes the handle to slide along the sloped undersides of the bridge-like structures. As the handle slides along the slope underside, it pulls the plate from which the bridge-like structures extend, in turn causing the plate to pull the central portion of the suction pad away from the surface with which it was in contact, while the outer portion of the suction pad remains in contact with that surface. As the central portion of the suction pad is pulled away from the surface, the air pressure between the suction pad and that surface decreases, creating a partial vacuum under the central portion of the suction pad, which, in turn causes the outer portion of the suction pad, which is still in contact with the surface, to adhere to the surface.
If the handle of the bowl suction device is so moved, the suction pad is adhered to the bowl, preventing the bowl from moving. Movement of the handle in the opposite direction in the slot relaxes the central portion of the suction pad and allows the suction pad to be easily removed from the surface to which it was formerly mated.
As will be appreciated from the above description, the counter suction device permits the base of the mixing bowl assembly to be firmly secured to the work surface or counter on which bowl assembly is placed. Similarly, the bowl suction device permits the bottom of the bowl to be firmly secured to the bowl suction pad. And, since the bottom of the bowl is rounded or hemispherical, the bowl may be firmly secured to the bowl suction pad at various orientations and angles.
The inventive mixing bowl assembly may be operated in different ways. The base may be secured or adhered to the counter by the suction pad while the bowl, when not adhered to its suction pad, may be moved and oriented at different angles or positions with respect to the base and work surface. The bowl may be secured or adhered to its suction pad while the based is not adhered to the counter by its suction pad. And, both the bowl and base may be secured to their respective suction pads, fixing both in their respective positions on the base and the counter. Of course, the bowl may also be secured at various angles and orientations with respect to the base and the counter by placing the bowl in its desired position and moving the bowl handle to cause the suction pad to adhere to and fix the bowl in that position.
Thus, one may fix the bowl at a desired position and still move the base and bowl to different positions; one may secure the base to the counter and move the bowl to a desired position; one may secure the bowl to the base and the base to the counter at the same time; or one may leave both base and bowl unsecured and moveable. Ingredients may be added to the bowl, mixed in the bowl, or added and mixed simultaneously in any of the described configurations of the bowl and base, allowing the cook or operator maximum flexibility in positioning and orienting the base and bowl, respectively.
The various permitted orientations of the bowl also allow ingredients to be added to a bowl fixed at a desired angle, allow ingredients to be mixed in the bowl while the bowl is fixed at an optimum angle for such mixing, allow the base and attached bowl to be moved without changing or disturbing the angle or orientation of the bowl, and allow the operator or cook to add and mix ingredients with both hands at the same time without having to hold on to or tend the bowl or base at all.
Certain terminology will be used in the following description. Words such as “top”, “bottom”, “upper”, “lower”, “upward”, “downward”, “rightward”, “leftward”, “above”, “below”, and the like, refer to those same directions in the properly oriented drawings. Words such as “inward”, “outward”, “inner”, “outer”, “central”, refer to the same directions or locations at, toward, or away from the geometric center of the object shown or referenced in the properly oriented drawings. This use of such terminology is for convenient reference, is not intended to be limiting (as, for example, if an embodiment of the invention is inverted or reversed), and includes the words specifically mentioned, derivatives thereof, and words of a similar nature or import.

Counter Suction Device
As shown in
The suction pad 60 is larger in diameter than the suction pad plate 61. The suction pad 60 has a central portion 68 and an outer portion 69. When the suction pad 60 is placed on the top side 64 of the suction pad plate 61, the outer portion 69 of the suction pad 60 extends beyond and outward from the suction pad plate 61. The central portion 68 of the suction pad 60 is situated on and connected to the top side 64 of the plate 61.
The handle 62 extends from the sloped underside 66 of one of the bridge-like structures 65, through a hole 70 in the pivot 63, along the sloped underside 66 of the other bridge-like structure 65, and outward thorough the elongated slot 13 in the side 6 of the base 2 above the bottom opening 11 of the base 2. The handle 62, so situated, is in sliding contact with the sloped undersides 66 of the bridge-like structures 65.
The counter suction assembly 14 is oriented so that the outer portion 69 of the suction pad 60, which extends outward from the plate 61, makes contact with the counter or work surface through the bottom opening 11 of the base 2.
Operation of Counter Suction Device
The counter suction device 14 is operated by moving its handle 62 from one side of its elongated slot 13 to the other. Movement of the handle 62 in one direction causes the handle 62 to slide along the slopes of the undersides 66 of the bridge-like structures 65. The slopes of the undersides 66 are oriented so that, as the handle 62 is moved in one direction, the handle 62 forces or pulls the plate 61 away from the counter or work surface.
Thus, as the handle 62 slides along the sloped underside 66, it pulls the plate 61 from which the bridge-like structures 65 extend away from the counter, in turn causing the plate 61 to pull the central portion 68 of the suction pad 60 away from the surface of the counter, while the outer portion 69 of the suction pad 60 remains in contact with the surface of the counter. As the central portion 68 of the suction pad 60 is pulled away from the surface, the air pressure between the suction pad 60 (and the plate 61, which is beneath a part of the pad 60) and the counter surface decreases, creating a partial vacuum under the central portion 68 of the suction pad 60, which, in turn causes the outer portion 69 of the suction pad 60, which is still in contact with the counter, to adhere to the counter. If the handle 62 of the counter suction device 14 is so moved in slot 13, the suction pad 60 is adhered to the counter, preventing the base 2 from moving.
When the counter suction device 14 is engaged, as described above, there is a force on the suction pad 60 caused by the partial vacuum that tends to pull the suction pad 60 toward the surface to which it is adhered. There is also a force generated by the stretching of the rubber (or other flexible) suction pad as it is pulled upward, urging the plate and suction pad toward the surface to which it is adhered. These forces are resisted by the handle 62, which holds the suction pad 60 (and the suction pad plate 61) in position via its contact with the bridge-like structures 65. (The resistance of the handle may be assisted by the inclusion of lock indentations described below.)
When the handle 62 is moved in the opposite direction (i.e., in a direction in the elongated slot 13 opposite from the direction described above to engage the suction device 14), the handle slides in the opposite direction along the sloped undersides 66 of the bridge-like structures 65, the suction pad 60 relaxes, and the suction plate 61 is allowed to move toward the surface to which it is adhered, which reduces the partial vacuum (increases the pressure between the suction plate 61 and the surface to which the suction device 14 is adhered). When the partial vacuum has been so reduced, the suction pad 60 is no longer adhered to the surface, and the counter suction device 14 can be easily removed from the surface to which it formerly secured.
Bowl Suction Device

Specifically, as shown in
The suction pad plate 91 is curved to fit the configuration (rounded in
The suction pad 90 is larger in diameter than the suction pad plate 91. The suction pad has a central portion 98 and an outer portion 99. When the suction pad 90 is placed on the top side 94 of the suction pad plate 91, the outer portion 99 of the suction pad 90 extends beyond and outward from the suction pad plate 91. The central portion 98 of the suction pad 90 is situated on and connected to the top side 94 of the plate 91.
The handle 92 extends from the sloped underside 96 of one of the bridge-like structures 95, through a hole 89 in the pivot 93, along the sloped underside 96 of the other bridge-like structure 95, and outward thorough the elongated slot 12 in the side 6 of the base 2 below the top opening 10 of the base 2. The handle 92, so situated, is in sliding contact with the sloped undersides 96 of the bridge-like structures 95.
Operation of Bowl Suction Device
The operation of the bowl suction device 15 is substantially similar to the operation of the counter suction device 14 described above.
The bowl suction device 15 is operated by moving its handle 92 from one side of its elongated slot 12 to the other. Movement of the handle 92 in one direction causes the handle 92 to slide along the upward slopes of the underside 96 of the bridge-like structures 95. The slopes of the undersides 96 are oriented so that, as the handle 92 is moved in one direction, the handle 92 forces or pulls the plate 91 away from the bottom 5 of the bowl 3.
As the handle 92 slides along the sloped undersides 96, it pulls the plate 91 from which the bridge-like structures 95 extend, in turn causing the plate 91 to pull the central portion 98 of the suction pad 90 away from the bottom 5 of the bowl 3, while the outer portion 99 of the suction pad 90 remains in contact with the bottom 5 of the bowl 3. As the central portion 98 of the suction pad 90 is pulled away from the bottom 5 of the bowl 3, the air pressure between the suction pad 90 (and the plate 91, which is beneath a part of the pad 90) and the bottom 5 of the bowl 3 decreases, creating a partial vacuum under the central portion 98 of the suction pad 90, which, in turn causes the outer portion 99 of the suction pad 90, which is still in contact with the bottom 5 of the bowl 3, to adhere to the bottom 5 of the bowl 3. If the handle 92 of the bowl suction device 15 is so moved in the slot 12, the suction pad 90 is adhered to the bottom 5 of the bowl 3, preventing the bowl 3 from moving.
The slopes of the undersides 96 of the bridge-like structures 95 are oriented so that, as the handle 92 is moved in the opposite direction (i.e., a direction opposite of that described immediately above) along the sloped undersides 96, the suction pad 90 relaxes and the plate 91 is allowed to move back toward the bottom 5 of the bowl 3, reducing the partial vacuum. Thus, movement of the handle 92 in the opposite direction in the slot 12 allows the suction pad 90 to be easily removed from the bottom 5 of the bowl 3 to which it is was formerly mated.
Operation of the Mixing Bowl Assembly
As will be appreciated from the above description, the counter suction device 14 of the mixing bowl assembly 1 permits the base 2 of the mixing bowl assembly 1 to be firmly secured to the work surface or counter on which bowl assembly 1 is placed. Similarly, the bowl suction device 15 permits the bowl suction device 15 to be firmly secured to the bottom 5 of the bowl 3. And, since the bottom 5 of the bowl 3 is rounded or hemispherical, the bowl 3 may be firmly secured to the bowl suction device 15 at various orientations and angles.
The mixing bowl assembly may be operated in many different ways.
The base 2 may be secured or adhered to the work surface by the counter suction device 14 while the bowl 3, when not adhered the bowl suction device 15, may be moved and oriented at different angles or positions with respect to the both the base 2 and the work surface. The bowl 3 may be secured or adhered to the bowl suction device 15, while the base 2 is not adhered to the counter by the counter suction device 14. Further, both the bowl 3 and the base 2 may be secured to their respective suction devices 15 and 14, thus fixing both in the respective positions in which they are secured.
As shown in
Thus, one may fix the bowl 3 at a desired position and still move the base 2 to a different location; one may secure the base 2 to the counter and move the bowl 3 to a desired position or angle on the base 2; one may secure the bowl 3 to the base 2 and the base 2 to the counter at the same time; or one may leave both base 2 and bowl 3 unsecured and moveable.
Ingredients may be added to the bowl 3, mixed in the bowl 3, or added and mixed simultaneously in any of the above described configurations of the bowl 3 and base 2, allowing the cook or operator maximum flexibility in positioning and orienting the base 2 and bowl 3 for various mixing, adding, and stirring tasks.
