Abstract
Description
- This application is a continuation-in-part of U.S. application Ser. No. 09/833,872, filed Apr. 12, 2001, which claims priority from U.S. Provisional Application Serial No. 60/196,380 filed Apr. 12, 2000, and U.S. Provisional Application Serial Nos. 60/274,184 and 60/274,183 both filed Mar. 9, 2001.
- The present invention generally relates to kitchen and culinary devices. More particularly, the present invention relates to a manually operated multi-function food processing, preparation and juicing unit, and a system for securely and removably attaching a food processor adapter to such a unit.
- There exist many hand operated devices for juicing, cutting fruit into segments, and cutting vegetables into a desired size and shape. However, these devices often require a substantial amount of exertion and force to perform their intended function. The use of these devices can be quite taxing to the ordinary users of such devices. Another disadvantage of such devices is the need for a device for each operation. For example, there must be stored a juicer, a wedger or segmenter, and perhaps several cutting implements for vegetables.
- There also exist various automated devices. Although these devices also include interchangeable components, allowing the user to perform more than one function with the device, they are rather large in size as well as expensive, and don't always perform all the intended tasks adequately, or do not perform certain functions at all.
- Another problem encountered with food processing, preparation and juicing units has been that the removable food processing adapters are not securely locked into position. This can cause one of the food processing adapters to rotate out of the mating position with the other adapter. Also, the adapters might move during the processing of the food, creating non-uniform preparation of the food, such as non-uniform vegetable slices or sticks. Another problem associated with the non-secure attachment of such adapters is that as the upper adapter is brought away from the lower adapter, it is not uncommon for the lower adapter to be removed from its position partially or even entirely. This requires the user to manually grasp the adapters and dislodge them from any remaining food that has been unprocessed and subsequently reposition the adapter.
- Accordingly, there is a need for a multi-functional unit which is capable of food processing, preparation and juicing. Such a unit should be relatively easy to operate so as not to require undue exertion on behalf of the user. Such a unit should also be capable of being re-configurable so as to perform a variety of tasks. What is also needed is a system for securely and removably attaching food processor adapters to such units. The present invention fulfills these needs and provides other related advantages.
- The present invention resides in a system for securely and removably attaching a food processing adapter to a food processing and juicing unit. Such food processing units typically have a holder at a base thereof, and a pressure assembly capable of being brought towards and away from the holder, oftentimes manually using a handle associated with the pressure assembly.
- The system includes an upper processing adapter removably attached to the pressure assembly. In a particularly preferred embodiment, the pressure assembly includes a semi-peripheral groove on the lower edge thereof into which an upper peripheral edge of the upper processing adapter is configured to be inserted. Typically, a manually actuated lock is associated with the pressure assembly and configured to releaseably hold the upper processing adapter in place. The lock includes a vertically slidable stop having a platform extending into the pressure assembly, and a spring interposed between the platform and the pressure assembly to bias the stop in a closed position.
- A lower processing adapter having a surface configuration which cooperates with the upper processing adapter to form a predetermined food processing function is removably attached to the holder. A first slot is formed in an upper portion of the holder, and a second slot is formed in the upper portion of the holder spaced from the first slot so that the first and second slots are generally opposite one another. The first slot extends into the top portion of the holder at a generally horizontal orientation. The second slot extends into the top portion of the holder at a generally vertical orientation. The lower processing adapter has a first tab that extends generally horizontally from a lower edge thereof and configured to be inserted into the first slot. A second tab includes a leg extending generally vertical from the lower edge of the lower processing adapter, and a foot extending transverse to the leg at an end thereof so as to be inserted into the second slot.
- A locking mechanism is associated with the second slot and configured to releaseably lock the second tab in place within the second slot. The locking mechanism in a particularly preferred embodiment is pivotally connected to the holder and includes a button having a prong extending downwardly therefrom and biased over the foot of the second tab when the lower processing adapter is attached to the holder. The prong prevents the second tab from being lifted from the holder until the button is actuated causing the prong to be removed from its bias position and permitting the second tab, and lower processing adapter, to be lifted from the holder. The lower processing adapter may include a handle for facilitating the insertion and removal thereof from the holder. A tab may also extend from the holder and be configured to be inserted into a notch formed in the lower processing adapter to further secure the lower processing adapter to the holder, and also to serve as a guide in the proper placement of the lower processing adapter.
- The system of the present invention securely attaches the food processing adapters to the food processing and juicing unit, preventing the adapters from rotating or becoming dislodged from their proper placement during operation of the unit. The system is designed such that an untrained user of the food processing and juicing unit can safely and quickly remove and exchange food processing adapters as meets the need of the user.
- Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the invention.

Awing nut 30 or the like holds thecrank arm 24 in place so that it is operably engaged with thegear 28. Thecrank arm 24 can be disengaged from thegear 28 and removed from themulti-functional unit 10 by looseningwing nut 30 and sliding the second end of thecrank arm 24 from its engagement with thegear 28. Such disengagement may be desirable when themulti-functional unit 10 is to be stored in a compact space. - With reference to FIGS. 5 and 6, the
gear 28 hascogs 32 which engageteeth 34 of arack 36 residing within thehollow post 14. Therack 36 is connected to apressure assembly 38 through the one ormore slots 18. Although the drawings illustrate asingle slot 18 formed in a front face of thepost 14, it should be understood that there may be other configurations, such as opposing slots formed in the sides of thepost 14 which could serve the same purpose. As thegear 28 of thecrank arm assembly 20 is rotated by rotatinghandle 22 and crankarm 24, therack 36 is moved upwardly or downwardly within thepost 14, causing thepressure assembly 38 to similarly move along the length of thepost 14.Crank assembly 20 is preferably fixed in place on thepost 14. Typically, thepressure assembly 38 is connected to therack 38 directly or by means of abracket 40 or ears attached to or extending from thepressure assembly 38 at one end thereof for connection to therack 36, particularly when theslots 18 are formed in opposing sides of thepost 14. Thus, thepressure assembly 38 is capable of moving along thepost 14 throughout the length of theslot 18. - Referring to FIGS. 1 and 2, a
holder 42 is immovably attached or otherwise fixed to an upper surface of thebase 12. Theholder 42 defines anaperture 44 through which processed food, juice, etc. can pass through. Theholder 42 is configured such that alower processing adapter 46 can be placed overaperture 44. Typically, thelower processing adapter 46 is releaseably attached to a top of the holder over theaperture 44 and held in place with alock 48, as will be described more fully herein. - Similarly, the
pressure assembly 38 is configured such that anupper processing adapter 50 is attached to a bottom surface thereof. Typically, theupper processing adapter 50 is inserted into an adapter-accepting groove and cavity formed at the bottom surface of thepressure assembly 38. Theupper processing adapter 50 is held in place withlock 52, as will be described more fully herein. In this manner, theupper processing adapter 50 is held securely in place untillock 52 is manually actuated to release theupper processing adapter 50. - With reference to FIGS. 2 and 3, the
upper processing adapter 50 has a predeterminedsurface configuration 54 which is intended to facilitate the food processing or juicing function desired. As illustrated in FIG. 3, theupper processing adapter 50 includes multiple square projections 56 rising from theupper processing adapter 50. Thelower processing adapter 46 includes a surface configuration 58 which cooperates and mates with the upper processingadapter surface configuration 54 to bring about the desired function. As illustrated in FIG. 2, the lower processing adapter surface processing configuration 58 comprises a grid of wires or cuttingblades 60 forming apertures which substantially mate with the square projections 56 of theupper processing adapter 50. Thus, when a potato, vegetable or the like is placed on thelower processing adapter 46, and thepressure assembly 38 brought towards theholder 42 by rotatinghandle 22, the potato, vegetable, or the like is cut into french fry or shoe string-like pieces. Theholder 42 is configured such thatpressure assembly 38 can be brought towards theholder 42 untilupper processing adapter 50 actually contacts or even passes through thelower processing adapter 46. - It will be appreciated by the reader that the
surface processing configurations 54 and 58 can be varied such that the vegetable is cut into different shapes, a piece of fruit is cored and cut into wedge-shaped segments, or citrus or the like is pressed to remove the juice therefrom. Themulti-functional unit 10 can accomplish all of these various food processing and juicing functions by replacing the upper andlower processing adapters - With the intended upper and
lower processing adapters holder 42 andpressure assembly 38, respectively, the intended food processing function is performed by rotatinghandle 22, causinggear 28 to rotate and moverack 36, and thus theupper processing adapter 50 positioned in thepressure assembly 38, downwardly towards thelower processing adapter 46 positioned onholder 42, as illustrated in FIG. 4. The desired cutting, juicing, etc. is thus performed. - With reference to FIGS. 1 and 2, the
holder 42 is configured such with relation to the base 12 so as to form acavity 62 therebetween. Thiscavity 62 is intended for capture and transfer of the processed food or juice which has been forced throughaperture 44. Preferably, thecavity 62 is dimensioned such that acontainer 64 can be placed thereunder to capture the processed food or juice. Thecontainer 64 can be placed within thecavity 62, or even be locked therein so as to prevent thecontainer 64 from inadvertently moving out of position during operation of themulti-functional unit 10. - As described above,
food processing adapters multi-function units 10 have had the tendency to disadvantageously move during the operation of theunit 10. Accordingly, themulti-functional unit 10 includes a system for securely and removably attaching thefood processing adapters respective holder 42 andpressure assembly 38. - With reference to FIGS.7-11, an upper portion of the
holder 42 includes afirst slot 66 extending generally horizontally into theholder 42. Asecond slot 68 is positioned generally opposite thefirst slot 66 and is directed into theholder 42 in a vertical orientation. Theholder 42 also includes atab 70 extending upwardly therefrom, typically adjacent to thefirst slot 66, whose purpose will be more fully described herein. - The
lower processing adapter 46 includes afirst tab 72 extending generally horizontally from a lower edge thereof, and configured to be inserted into thefirst slot 66. Asecond tab 74 extends downwardly from a lower edge of thelower processing adapter 46 in a generally vertical orientation. Thesecond tab 74 is configured such so as to be introduced into thesecond slot 68. Thesecond tab 74 includes a leg portion 76 extending vertically, and afoot 78 extending from the leg 76 at an orientation generally transverse to the leg 76. - A
notch 80 is formed in the outer periphery of thelower processing adapter 46 which is sized and configured such so as to receive thetab 70 extending upwardly from theholder 42. Thetab 70 and notch 80 aid the user in aligning thelower processing adapter 46 to its proper orientation, and also serves to more securely hold thelower processing adapter 46 in place. - With reference now to FIGS.9-11, the
locking mechanism 48 includes a finger-actuatedbutton 82 having at least oneprong 84 extending downwardly therefrom and into theholder 42 adjacent to thesecond slot 68. The button and prongs 82 and 84 are pivotally positioned within theholder 42 via side bars 86. A resiliently flexibleinternal lip 88 of theholder 42 biases theprongs 84 into the vertical, and closed, position. Upon pressing thebutton 82, theprongs 84 are pivoted into contact with thelip 88 which deforms slightly. Upon release of the pressure, thelip 88 pushes theprongs 84 back into their closed position. - To secure the
lower processing adapter 46 to theholder 42, the user aligns thetab 70 andnotch 80, insertsfirst tab 72 into thefirst slot 66, and pushes thesecond tab 74 intovertical slot 68. Thelower processing adapter 46 may include ahandle 90 extending from a front edge thereof to assist in this process. Thehandle 90 also serves as a safety feature as oftentimes the workingsurface 60 of thelower processing unit 46 is comprised of sharp edges. Thehandle 90 allows the user to obtain thelower processing unit 46 from storage, properly insert it into theholder 42, and remove it without fear of coming into contact with the workingsurface 60. However,such handle 90 is not critical to the invention. As can be seen in FIG. 11, once thesecond tab 74 is inserted intoslot 68, theleg 78 of thetab 74 is positioned under theprongs 84 of thelocking mechanism 48. Thus, thelower processing adapter 46 cannot be removed from theholder 42 without actuating thelocking mechanism 48, as described above, in order to move theprongs 84 away from thefoot 78 so that thesecond tab 74 can be removed from theslot 68. Due to the two points of attachment, as well as both the horizontal and vertical orientations of thetabs slots lower processing adapter 46 cannot be lifted from theholder 42 unintentionally, nor will it rotate out of position. - With reference now to FIGS. 7 and 12-13, an outer
peripheral edge 92 of theupper processing adapter 50 is configured to be received within asemi-peripheral groove 94 formed at the bottom surface of thepressure assembly 38. As illustrated in FIG. 7, an upper surface of theupper processing adapter 50 may includetracks 96 which mate with corresponding tracks or grooves on the lower surface of thepressure assembly 38 to further assist the user in guiding theupper processing adapter 50 in place, as well as holding theupper processing adapter 50 in its proper orientation and position. - A
locking mechanism 52 further holds theupper processing adapter 50 in place within thepressure assembly 38. The lockingassembly 52 includes a manually actuated verticallyslidable stop 98 having aplatform 100 extending into thepressure assembly 38, and aspring 102 interposed between theplatform 100 and thepressure assembly 38 to bias thestop 98 in a closed position. Thus, to insert theupper processing adapter 50 in place, thestop 98 is pressed upwardly, compressing thespring 102, as the upper processing adapterperipheral edges 92 are slid into theassemblies grooves 94. Upon releasing thestop 98, thespring 102 biases theplatform 100 downwardly, moving thestop 98 in front of a leading edge of theupper processing adapter 50 to hold it in place. With such an arrangement, theupper processing adapter 50 cannot rotate, nor move from its position within thegrooves 94 within thepressure assembly 38 until it is intentionally removed therefrom. - With reference now to FIG. 14, the
multi-functional unit 10 may include a locking mechanism 104 for selectively locking theunit 10 onto a flat surface. As illustrated in FIG. 14, this locking mechanism 104 preferably comprises a vacuum lock mechanism 104 associated with thebase 12. The vacuum lock mechanism 104 includes a lever 106 attached to a generally circular membrane 108 attached at its periphery to a bottom surface of thebase 12. The lever 106 extends out an aperture 110 of thebase 12 and is pivotable between a released state wherein the membrane 108 is in a relaxed and generally flat configuration, and a locked state wherein the lever 106 upon pivoting moves the membrane 108 upward into a generally convex configuration, creating a vacuum seal between the base 12 and flat surface underlying the base 12 so that thebase 12 is suctioned securely onto the flat surface. Such a locking mechanism 104 is advantageous in that themulti-functional unit 10 can be placed upon a table, countertop, etc. having a flat and smooth surface and locked in place thereon by pivoting lever 106. - With the
multi-functional unit 10 immobile, food is more easily processed, juice extracted, etc. without fear that themulti-functional unit 10 will topple or otherwise become unstable during the manual rotation of thehandle 22. This also frees the hands of the user so that one hand can hold onto the fruit or vegetable positioned between thepressure assembly 38 andholder 42 until thehandle 22 is rotated such that thepressure assembly 38 applies sufficient pressure to the vegetable or fruit that it no longer needs to be held in place. The user can then grasphand grip 16 while continuing to rotatehandle 22 to complete the desired food processing function. Such a vacuum lock mechanism 104 is preferred over other locking mechanisms, although such can be incorporated into the invention, as it does not require the proper positioning on a ledge, adjustment of parts, etc. that such locking mechanisms require. However, the unit can be designed such that the locking mechanism 104 can be removed, so that processed food can fall directly through theholder 42 and onto the counter or cutting board or other working surface. - Although several embodiments have been described in detail for purposes of illustration, various modifications may be made to each without departing from the scope and spirit of the invention. Accordingly, the invention is not to be limited, except as by the appended claims.
