This invention relates generally to kitchenware and, in particular, to a mandoline slicer for use is slicing fruits, vegetables, and other foods.
The mandoline slicer is well known in the prior art. The device is set on a work surface. It has a flat upper surface, which may be angled with respect to the work surface. A blade is positioned near the center of the device. A food article is pushed, in sliding fashion, over the upper surface of the slicer, and, as the food article is moved over the blade, it is sliced in uniform slices. The uniform slices of food may then be eaten, served, or mixed or combined with other foods. The slicer, of course, is a very useful kitchen implement, because it yields uniform slices and it is easy to use and relatively stable when used.
Nevertheless, mandoline slicers are relatively large and take up considerable space when stored. The slicer may have multiple blades or attachments for different types of cuts or slices; these, too, must be specially handled for storage. Mandoline slicers also have a tendency to move about on the counter when bulky, sticky, or relatively hard foods are being sliced, in which case the user must keep a solid grip on the slicer so that it does not move about during slicing. If the slicer were to move about during slicing, it could affect the uniformity of the slices, or cause the slicer to tip or fall off the work surface or kitchen counter and, potentially, cause injury.
Many such slicers also are equipped with means to adjust the relative angle or height of the blade and upper surface so that the thickness of slices may be varied. Such adjustments may be made with a knob, ledges, or other types of structures that are suitable to adjust the angle of either the blade, the upper surface of the slicer, or both. Such structures can be difficult to operate or require the user to engage in considerable manipulation of the knob or the parts of the slicer.
It is therefore be desirable to have a mandoline slicer that could be made smaller or more compact for storage, include a convenient structure to store the blades and other cutting attachments, be securable to a counter or work surface during the slicing operation, and have an easy means for adjusting the relative heights of the blade and upper surface of the slicer in a known incremental manner so that the thickness of food slices can be easily and dependably regulated.
It is also desirable to have a low profile, compact device for securing the slicer to the work surface so that the slicer assembly itself does not become bulky or unnecessarily or uncomfortably high for the user when it is secured to the work surface. Further, it is desirable to have such a device which could be moved to a storage position under the slicer, thus reducing the space necessary to store the slicer.
The mandoline slicer of the invention has a compact, low profile suction device in a housing that is hinged to the front of the slicer. The suction device is engaged and disengaged by moving a lever horizontally in a slot in the housing to very firmly secure the front of the slicer to the work surface for use. The housing may be rotated on its hinges to be positioned outside the front of the slicer during use or to be positioned under the slicer for storage.
Food is sliced on the slicer by moving the food from the rear to the front of the slicer. The food is placed on the surface of a rear platform of the slicer and then moved slidingly forward onto a front platform of the slicer. A blade is located in a central portion of the slicer between the rear and front platforms such that, when the food slides from the rear platform to the front platform, the food intersects the blade and is sliced.
The relative heights of the blade and the front of the rear platform determine the thickness of slices that are cut on the slicer. The greater the difference in the heights of the blade and the front of the rear platform, the thicker a slice of food is cut. Thinner slices of food are cut when the difference in the heights of the blade and the front of the rear platform are smaller.
The relative heights of the front of the rear platform and the blade are changed by moving a lever horizontally in a slot in the side of the slicer. The lever easily slides along a sloped flange on the rear platform of the slicer, thus raising and lowering the front of the rear platform. The lever is geared so that the changes in the relative heights of the blade and the front of the rear platform are incremental. As a result, the thickness of food slices may be varied by known incremental amounts.
Rear legs or a rear support of the slicer contain compartments or slots for convenient, compact storage of the blades or attachments, such as a Julienne-style cutter. The rear legs fold under the slicer to provide a compact assembly for storage.

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.
Slicer Assembly
Frame
As shown in
Front Platform
As best shown in
Blade
The blade 5 is inserted into and removed from the blade slot 12 via use of a blade handle 21. A frontward portion 22 of the blade 5 fits under the front platform 4; a rearward portion or edge 23 of the blade 5 is exposed to slice food that is moved over the rear platform 6 of the slicer 1. (See
Rear Legs
As shown in
As shown in
Pivot Base
A pivot base 27 is formed on or attached to the pivot support strip 15 of the frame 3 of the slicer. The pivot base 27 has triangular section, radial teeth 28. (See
Pivot
The pivot 8 has triangular section, radial teeth 29 that cooperate with the triangular section, radial teeth 28 of the pivot base 27 so that they movably fit together as shown in
As shown in
Handle and Bar
The handle 9 is inserted into and through hole 31 a as shown in
So constructed, the handle 9 may be moved sideways (approximately horizontally) via grip 35 in handle slot 13. As the handle 9 is moved sideways in the handle slot 13, the pivot 8 rotates or pivots with the handle 9 and moves incrementally over the pivot base 27. The handle 9 may be so moved, in specific increments, from one side of the handle slot 13 to the other and back again. As the handle 9 moves, the inward portion 33 of handle 9 slides along the surface of the handle support 16a, and the end 36 of bar 32 slides along the surface of handle support 16b, as shown in
Rear Movable Platform
As shown in
The rear movable platform 6 also has downward extending flanges 38 and 39 that extend downward at right angles from the platform 6. (See
Incremental Adjustment of Angle or Slope of Rear Movable Platform
Thus, when the handle 9 is at the frontward part 42 of the handle slot 13, the flange 38 rests on handle 9, the longer, rear part 41 of flange 39 rests on bar 32, and a front edge 45 of the rear platform 6 is nearly even with the rearward portion or edge 23 of the blade 5. If food is then moved on the surface of platform 6 from the rear toward the front of the slicer 1, the food cut is very thin, because the platform 6 is nearly even with the rear edge 23 of the blade 5. (See
When the handle 9 is at the rearward part 43 of the handle slot 13, the flange 38 rests on handle 9, the shorter, front part 40 of the sloped flange 39 rests on bar 32, and the front edge 45 of the rear platform is lower than the rearward portion or edge 23 of the blade 5. (The platform 6 is also lower at its front edge 45 that at its rear curled portion 37 and, thus, slopes from the rear of the slicer down toward the front of the slicer.) If, with the platform 6 in this position, food is moved on the surface of the platform 6 from the rear toward the front of the slicer 1, a relatively thick cut is made in the food, and a thick slice of food is produced, because the front edge 45 of the platform is lower than the rearward portion or edge 23 of the blade 5.
When the handle 9 is midway between the frontward part 42 and the rearward part 43 of the handle slot 13, the flange 38 rests on the handle 9, and the sloped portion 44 of flange 39 rests on the bar 32. With the handle 9 in this position, the front edge 45 of the rear platform 6 is somewhat lower than the rearward portion or edge 23 of blade 5, but not as much lower as when the handle 9 is at the rearward part 43 of the handle slot 13. (In other words, the platform 6 is lower at its front edge 45 that at its curled portion 37 and slopes from the rear of the slicer 1 down toward the front of the slicer 1, but does not slope as much as when the handle 9 is at the rearward part 43 of the handle slot 13.) If, with the platform 6 in this position, food is moved on the surface of the platform 6 from the rear toward the front of the slicer 1, the food slice is cut, but the slice that is cut is not a thick as when the handle 9 is at the rearward part 43 of the handle slot 13.
More specifically, as the handle 9 is moved from the frontward part 42 and the rearward part 43 of the handle slot 13, the front edge 45 of the rear platform 6 is lowered—i.e., the angle or degree of slope of the rear platform 6 is increased. As the angle or degree of slope of the rear platform 6 is increased, the front edge 45 of the rear platform 6 becomes increasingly lower than the rearward portion or edge 23 of the blade 5, thus producing thicker slices of food when food is moved from the rear to the front of the slicer over the rear and front platforms 6 and 4, respectively. Thus, by moving the handle 9 different distances in the handle slot 13, the thickness of the slice of food cut on the slicer can be determined and regulated. When the handle 9 is moved toward the frontward part 42 of the handle slot 13, the slices produced are thin; when the handle 9 is moved toward the rearward part 43 of the handle slot 13, the slices produced are thicker.
Moreover, since the handle 9 and the bar 32 are connected to the pivot 8, and pivot 8 has the teeth 29 that cooperate with and slide over the teeth 28 of the pivot base 27 as the handle 9 is moved in the handle slot 13, the movement of the handle 9 in the handle slot 13 is incremental—i.e., it moves in discrete steps from one end of the handle slot 13 to the other. And, since the movement of the handle 9 in the slot 13 is in discrete, incremental steps, the angle or slope of the rear platform 6 is also changed in discrete, incremental steps, because the movement of the handle 9 changes the slope or angle of the rear platform 6. Thus, the thickness of the slices of food moved over the slicer 1 can be determined, changed, and regulated in discrete, incremental steps by moving the handle 9 to different positions in the handle slot 13.
Suction Device Housing
So constructed, the housing 2 may be rotated underneath the frame 3, as shown in
Although the hinge slot 10 and bar arrangement are described herein, it is understood that any hinge arrangement for the suction housing 2 could be used for the stated purpose of rotating the suction housing 2 from a position out in front of the slicer frame 3 to a position underneath the slicer frame 3 or from a position underneath the frame 3 to a position out in front of the frame 3. For example, an axle could be used for this purpose, or pins could extend from the frame 3 and be rotatingly inserted to the suction housing 2 to accommodate such rotation. Indeed, any structure that would permit the suction housing 2 to rotate under and out from under the frame 3 would be satisfactory for this purpose.
Suction Device
The suction device housing 2 of the slicer 1 houses a suction assembly 50, as shown in
The suction assembly 50 comprises a suction pad 60, a suction pad plate 61, a handle 62, and a pivot 63. The suction plate 61 has a top side 64. Two spaced-apart bridge-like structures 65 extend away and upward from the top side 64 of the plate 61. Each bridge-like structure 65 has an underside 66 that is ramped or sloped. The pivot 63 is situated between the bridge-like structures 65.
The suction pad 60 is larger in diameter than the suction pad plate 61. The suction pad 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 59 in the side 56 of the suction device housing 2 above the bottom opening 58 of the suction device housing 2. The handle 62, so situated, is in sliding contact with the sloped undersides 66 of the bridge-like structures 65.
The suction assembly 50 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 58 of the suction device housing 2.
Suction device 50 is operated by moving its handle 62 from one side of its elongated slot 59 to the other.
Movement of the handle 62 in one direction causes the handle 62 to slide along the upward slopes of the underside 65 of the bridge-like structures 65. As the handle 62 slides along the slope underside 65, it pulls the plate 61from which the bridge-like structures 65 extend, in turn causing the plate 61 to pull the central portion 68 of the suction pad 60 away from the counter, while the outer portion 69 of the suction pad 60 remains in contact with the counter. As the central portion 68 of the suction pad 60 is pulled away from the surface, the air pressure between the central portion 68 of the suction pad 60 and the counter 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.
Movement of the handle 62 in the opposite direction in the slot 59 relaxes the central portion 68 of the suction pad 60, causes the central portion of the suction pad 60 to move toward the counter, increases the pressure under the central portion 68 of the suction pad 60, dispels the partial vacuum, and allows the suction pad 60 to be easily removed from the surface to which it is was formerly mated.
Operation of the Suction Device
In order to operate the suction device 50 and engage it with a work surface, the suction device housing 2 is rotated from its storage position under the frame 3 to an engagement position out in front of the slicer 1. (The legs 7 are also unfolded from under the frame 3 of the slicer 1 so that the rear portion of the slicer 1 may stand on the work surface.)
The slicer 1 is then placed in a desirable location on a work surface or counter. In this position, the outer portion 69 of the suction pad 60 is in contact with the countertop. The handle 62 of the suction device 50 is moved in the elongated slot 59. As the handle 62 moves in the slot 59 the central portion 68 of the suction pad 60 is raised upward, creating a partial vacuum under the central portion 68 of the suction pad 60 while the outer portion of the 69 of the suction pad 60 remains on the countertop. The vacuum or suction so created under the central portion 68 of the suction pad causes the slicer 1 to stick or adhere to the counter in the desired location.
So adhered, the slicer1 will not be moved or tipped on the counter or work surface when the slicer 1 is in operation.
If it is desired to move the slicer 1 to a different location, the handle 62 of the suction device 50 is moved in the opposite direction in the slot 59 in the side 56 of the suction device housing 2 to relieve the partial vacuum under the central portion 68 of the suction pad 60. The slicer 1 may then be moved to a different location on the countertop, where it may again be adhered by suction in the manner stated above.
Operation of Slicer
The slicer 1 is removed from any location in which it might be stored. The rear legs 7 are folded out from beneath the frame 3, and the suction device housing 2 is rotated on its hinge connections to move it from under the frame 3 of the slicer 1 until it extends outward from the front of the slicer 1. The slicer 1 is then placed in a convenient location on a work surface. When the slicer 1 is so positioned, the lever or handle 62 of the suction assembly 50 is moved in slot 59 until the suction device 50, and thus the slicer 1, is secured to the work surface.
A Juilenne cutting attachment 26 may removed from one of the slots 25 between the rear legs 7 of the slicer 1 and inserted into the slot 12 in the frame 3 so that Julienne style cutting is enabled. However, if a Julienne style cut is not desired, the Julienne attachment may be left in one of the storage slots 25 between the rear legs 7 of the slicer 1.
The Lever or handle 9 is then moved incrementally in slot 13 until the front 45 of the rear platform 6 is a distance below the rearward edge 23 of the blade 5 sufficient to make slices of a thickness desired by the user. An article of food is then placed on the rear platform 6 and moved from the rear of the slicer 1 toward the front of the slicer. As the food is so moved, it is intersected by the blade 5, which slices a portion of food from the article. (A block or handle, which is not shown, may be placed on top of the food before it is moved from the rear toward the front of the slicer 1 to protect the user from being cut by the blade.)
Upon completion of the slicing, the lever 62 is moved in the opposite direction in slot 59 to release the suction device 50 from the work surface. The slicer 1 may then be cleaned. Thereafter, the suction housing 2 is rotated back under the frame 3, the blade 5 may be removed from slot 12 and stored in one of the slots 25 in the legs 7, and the legs may be rotated back under the frame 3. The slicer 1 is then compacted for storage and may be stored.
It is understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
