Description
IMPROVEMENT8 TO FOOD CHOPPERS
This invention relates to improvements to hand held food choppers of the kind having a cup-shaped housing to be placed over the food to be chopped.
There are currently a large number of different food choppers on the market. However, the majority of these choppers are of a substantially similar construction. Known food choppers, as these traditional food choppers will be referred to hereafter, typically comprise a cup-shaped housing to be disposed in an inverted position over the foodstuffs to be chopped, an actuating stem disposed in an upper region of the housing and projecting upwardly out of the housing, an impact button fixed to an upper portion of the actuating stem, a cutting member fixed to a lower end of the actuating stem, a stripper plate disposed in a lower portion of the cup-shaped housing for removing chopped food from the cutting member, a transparent cylinder which engages a lower portion of the cup shaped housing and means for rotating the blade member upon actuation of the device by the application of a downward force on the impact button.
These food choppers, whilst adequately fulfilling the purpose for which they were designed, suffer from a number of disadvantages that impair their use.
Firstly, the cutting member typically comprises a convoluted zigzag blade mounted in an injection moulded plastic dish.
This convoluted blade causes food to become trapped at the apex of the convolutions thereby causing the device to seize up and become jammed. In addition, the convoluted blade requires that the stripper plate has a similar convoluted aperture formed therein. Thus, a significant disadvantage subsists in that the user often finds difficulty in aligning the blade and corresponding stripper plate aperture.
Secondly, these food choppers suffer from a disadvantage that the rotating means, whilst enabling the blade member to rotate, also causes the actuating stem to rotate thereby causing significant discomfort to the user who grasps the actuating stem during use. Attempts have been made in the past to rectify this problem, but these attempts have been largely ineffectual.
Finally, known food choppers require that the chopper be operated on a flat planar surface which gives rise to problems regarding food leakage and possible bacterial contamination.
It is an object of the present invention therefore to provide a food chopper that has an improved rotation member whereby the member grasped by the user is not subjected to any rotational force.
It is a further object of the present invention to provide a cutting member that has a blade of a shape that is without convolutions thereby enabling the easy removal of chopped food from the blade.
It is a still further object of the present invention to provide means for allowing the easy assembly of the blade member and stripper plate.
It is a still further object of the present invention to provide means for attachment to the base of the device which prevents food leakage and is impervious to moderate temperature fluctuations.
Thus, in accordance with the present invention, there is provided a device for chopping foodstuffs comprising: a cup shaped housing to be disposed in an inverted position over the foodstuff to be chopped; an actuating stem disposed in the housing and extending therefrom, said actuating stem having an impact button provided thereon; a cutting member provided within the housing to make impact with the foodstuff when pressed in a downward direction through a stripper plate in opposition to energy storage means; an actuating axle for joining said cutting member to said actuating stem; a cylinder mountable on said housing thereby defining an area into which the foodstuffs to be chopped may be placed; and rotation means acting with said actuating stem to rotate said cutting member on actuation of the device.
In one embodiment, the cutting member comprises a cutting plate having at least one cutting blade fixed therein.
Preferably, the cutting plate has three blades mounted therein and each of said blades is approximately v-shaped, has an apex angle of 60 degrees and is mounted at 60 degrees to its neighbour.
Preferably, the cutting blades have apertures formed in an upper portion thereof, said apertures being filled with material at the time of manufacture of said cutting plate.
In another embodiment, the chopper further comprises a dish mounted on said cylinder. The dish may have sealing means provided on its periphery. The sealing means may comprise an inner curb and an outer curb spaced therefrom, the spacing being slightly larger than the cylinder thickness.
Preferably, the stripper has a number of apertures formed therein, the number of apertures corresponding to the number of cutting blades, and has blade alignment means mounted on a top surface thereof. The blade alignment means may comprise a number of members each of which has a substantially triangular cross-section. These members may be disposed between apertures.
The energy storage means may comprise a spring circumscribing said actuation axle and acting on said actuation stem and an interior wall of said housing.
In another embodiment, the rotation means comprises a set of cams mounted on said actuation stem, a set of upper projections and a set of lower projections formed in between said upper projections, said projections being sized so as to retain said cams snugly therewithin.
The lower projections may be formed on an interior wall of an upper portion of said housing and the upper projections may be formed on an interior wall of a second rotation member joined thereto.
Alternatively, the upper and lower projections may be formed integrally with said housing and on an interior wall thereof.
Preferably, each of said upper projections comprise a first v-shaped member, an upper notch and a second v-shaped member and each of said lower projections comprise an inverted vshaped member and a notch.
In operation, each of said cams is moved from each upper notch to an adjacent upper notch upon actuation of the device.
Preferably, the impact member is free to rotate about said actuating stem in isolation of any rotational movement of said actuating stem.
A preferred embodiment of the present invention will now be described, by way of non-limitative example, in conjunction with the following drawings, in which:

Figure 4a,
Figure 5 is a sectional view of the transparent cylinder,
Figure 6 is a cross sectional view along a diameter of the base sealing member (the dish),
Figure 7a is a plan view of the top surface of the stripper plate, and Figure 7b is a cross sectional view along the line I---I of figure 7a.
Figure 1 illustrates a food chopper 1 according to the present invention. The chopper 1 comprises a cup shaped housing 3, a transparent cylinder 5, upper rotation means 7, a stripper plate 8, a dish 9, an impact member 10 provided with a top cap 11 and plunger means 12. The cup-shaped housing 3 is provided with lower rotation means 13 formed integrally on an interior wall of an upper portion of the cup-shaped housing 3.
The stripper plate 8 is sized so as to be fittable within a lower portion of the cup shaped housing 3 and the transparent cylinder 5 is sized so as to be able to fit over the cup shaped housing and stripper plate and to hold them securely therewithin. The transparent cylinder creates an aperture into which the foodstuffs to be chopped may be inserted when the device is fully assembled.
The plunger means 12 comprises an actuating stem 15, an actuating axle 17, spring means 19 circumscribing said axle 17, a cutting plate 21 and cutting blades 23. The plunger means 12 is disposed within the cup shaped housing 3 and extends either side of an internal wall 4 in the cup shaped housing 3.
The actuating stem is provided with cam means 25 which are engageable with the upper 7 and lower 13 rotating means and together serve to rotate the cutting blades 23 upon actuation of the device. The actuating stem 15 is additionally provided with a knob 27 which is sized so as to be engageable with a corresponding aperture in the impact member 10. The knob 27 is of hollow construction and is capable of secure engagement with the axle 17. The impact member 10 is capable of rotational movement independent of any rotational movement undertaken by the plunger means 12.
The cutting blades 23 are securely fixed to the cutting plate 21. The cutting plate 21 is securely fitted to the axle 17 and is capable of rotational movement therewith. The axle 17 passes through an aperture in the internal wall 4 so that the cutting plate 21 is brought into close proximity with a lower surface of the interior wall 4. The axle 17 is fitted, at its upper end, to the actuating stem knob 27. The spring means 19 is provided between and in abutment with the actuating stem 15 and the interior wall 4. The actuating stem 15, axle 17, cutting plate 21 and cutting blades 23 are securely fitted together and capable of sympathetic rotation upon actuation of the device.
The impact member 10 is rotatably mounted on the knob 27 and is free to rotate in isolation of any rotational movement undertaken by the knob 27. The impact member 10 is fixed to the actuating stem 15 by way of washers 29. The top cap 11 provides access to the washers 29 during assembly of the device and is securely fitted to the impact member 10 during use.
The stripper plate 8 is provided, on its upper surface, with blade alignment means 31 which serve to facilitate the insertion of the blades 23 into the stripper 8. The stripper plate 8 rotates in synchronisation with the blades 23 when the device is actuated.
The dish 9 is provided with sealing means 33 which enables the dish 9 to be fitted to the transparent cylinder 5 regardless of any ambient temperature fluctuation that may cause thermal expansion or contraction of the dish 9.
In order to operate the device, foodstuffs are placed within a bowl formed by the transparent cylinder 5 and dish 9. The stripper plate 8 is then inserted into the transparent cylinder 5 in such a manner that it lies substantially parallel with the dish 9. The cup shaped housing 3 is then inserted into the transparent housing in an inverted position as shown in Figure 1.
Pressure on the impact member 10 causes the plunger means 12 to move vertically down towards the foodstuff to be chopped.
The cams 25 interact with the upper 7 and lower 13 rotating means and serve to rotate the plunger means 12 in a clockwise direction. Continued application of pressure causes the blades 23 to chop the foodstuff provided within the bowl until the blades 23 come into abutment with the dish 9. At this point, the spring means 19 is at its fully compressed position so that, upon release of the downwards pressure, the spring means 19 enables the plunger means 12 to move upwardly into the housing 3. On the upward stroke, the cams 25 interact with the upper 7 and lower 13 rotating means once more to rotate the plunger 12 means in a clockwise direction. Obviously, the direction of rotation is immaterial; however it is important that the plunger means 12 rotates in the same direction on both the upward and downward strokes.It should also be noted that the impact member 10 does not rotate in sympathy with the plunger means 12 and indeed this is a significant advantage of the instant invention.
Repeated actuation and release of the device causes the blades 23 to be rotated and the foodstuffs to be finely chopped.
Figures 2a and 2b are enlarged views of an upper portion of the plunger means 12 of Figure 1. The axle 17, knob 27, actuating stem 15 and cams 25 may be clearly seen. The axle 17 may be push fitted with the knob 27, or other means may be employed. The actuating stem 15 is provided with a cam 25 at 90 degree intervals around its periphery. Obviously, a different number of cams may be employed without departing from the scope of the appended claims. However, testing has shown that best results are obtained with four cams provided at 90 degree intervals.
Figure 3 is a development of interior walls of the upper 7 and lower 13 rotating means of Figure 1.
The upper 7 rotating means is provided with four sets of upper protrusions 35 on an interior wall of the upper rotating means 7. The lower rotating means 13 is provided with four corresponding lower protrusions 37 on an interior wall of the housing 3 and disposed so as to fall into spaces left by the upper protrusions 35.
Each of the upper protrusions 35 comprise a first v-shaped member 39, an upper notch 41 and a second v-shaped member 43. Each of the lower protrusions 37 comprise an inverted vshaped protrusion 45 and a lower notch 47.
The upper 7 and lower 13 protrusions are sized so as to hold the cams 25 in secure engagement thereabout without touching any other part of the actuating stem 15. The broken line 49 indicates the path of one of the cams 25 through the upper 7 and lower 13 rotation means.
As shown in Figure 1, the upper 7 and lower 13 rotation means may be formed from two separate bodies, or they may be integrally moulded on an interior wall of an upper portion of the cup-shaped housing 3.
The upper 7 rotation means is preferably engaged with the lower 13 rotation means and joined thereto by glue or other known permanent retaining means.
The actuating stem 15 is inserted into the upper 7 and lower 13 rotating means by way of apertures 51 provided between the upper protrusions 35. The plunger means 12 is then depressed until the cams 25 are clear of the second vshaped members 43. The plunger means 12 is then operated until the cams 25 fall into the upper notches 41. The plunger means 12 is then held within the upper 7 and lower 13 rotating means until such a time as the above operation is repeated in reverse.
In operation, the plunger means 12 is depressed against the action of the spring means 19 until the cams 25 abut the inverted v-shaped member 37. The inverted v-shaped member 37 causes the cams 25 and attached actuating stem 15, axle 17, cutting plate 21 and blades 23 to rotate about the axle 17 until the cams 25 fall into the lower notches 47. At this point the blades 23 are fully extended from the housing 3 and are in abutment with the dish 9. This point will be referred to hereafter as the down point.
To return the blades 23 within the housing 3, pressure is released from the plunger means 12 and the cams 25 rise up a wall of the adjacent inverted v-shaped member 37 due to the action of the spring means 19 on the interior wall 4.
The cams 25 then contact again the first v-shaped member 35 on the upper rotating means 7 and the actuating stem 15 is rotated once more until the cams 25 return to the upper notches 41. At this point, the blades 23 are fully withdrawn into the housing 3 and the chopper 1 is in its up position.
The second v-shaped member 43 prevents the cams 25 from travelling into the aperture 51 thereby releasing the actuating stem 15 from the rotating means.
Repeated application and release of pressure on the plunger means 12 causes the cams 25 and attached stem 15, axle 17, cutting plate 21 and blades 23 to rotate about the axle 17 and chop the foodstuff disposed within the bowl formed by the transparent cylinder 5 and the attached dish 9. Each cycle of cam movement from the up position through the down position and back to the up position causes the blades 23 to rotate by 90 degrees.
Obviously, the scope of the appended claims is not limited to the number of cams and corresponding v-shaped members provided within the device. It will be obvious to one skilled in the art that the number of cams and corresponding v-shaped members may be varied at will. However, it is essential that there are at least as many upper and lower protrusions as cams.
It will also be obvious that one could provide two cams for engagement with four sets of protrusions. Each cam would be provided at 180 degree intervals on the periphery of the actuating stem and the corresponding projections would be formed at 90 degree intervals on the interior of the housing and upper rotating means. Similar multiples are also conceived.
Figure 4a is a plan view of the base of the cutting plate 21 and shows the angular placement of the three blades 23. Each blade 23 is of a substantially v-shape and has an angle of approximately 60 degrees at its apex. Each v-shaped blade 23 is disposed at 60 degrees from its neighbour.
Thins arrangement allows the blades 23 to have a maximum apex angle whilst also affording maximum chopping efficiency.
Obviously, a larger or smaller number of blades 23 may be provided. However, the wide apex angle of each v-shaped blade 23 is a feature of the present invention that allows for easy cleaning of the chopper blades 23. Thus, increasing the number of blades 23 and consequently decreasing the apex angle would not offer any improvement to the operation of the device.
Figure 4b shows a side elevation of one of the blades 23 depicted in figure 4a before it has been permanently attached to the cutting plate 21. Each blade 23 has a number of apertures 53 formed in an upper arm portion thereof. The cutting plate 21 may then be formed from injection moulded plastic in such a way that, at the time of forming the cutting plate 21, the plastic is injected through the blade apertures 53 thereby permanently securing the blades 23 to the cutting plate 21. Other attachment methods may be employed if preferred.
Figure 5 is a sectional elevation of the transparent cylinder 5 showing retention ledges 55 and 57. The lower retention ledge 57 is sized so as to receive and support the stripper plate 8. The upper retention ledge 55 is sized so as to receive and support the cup shaped housing 3. The stripper plate 8 is free to rotate in sympathy with the rotation of the blades 23 and attached cutting plate 21, axle 17, actuating stem 15 and cams 25.
Obviously, it is not essential that the cylinder 5 be manufactured from a transparent material; however, the transparency of the cylinder 5 does allow the user to ascertain when the foodstuffs have been chopped to a satisfactory degree.
Figure 6 is a cross sectional view along a diameter of the dish 9. The sealing means 33 may be seen in cross section.
The sealing means 33 comprises an inner curb 59 and an outer curb 61 spaced therefrom. The outer curb 61 is taller than the inner curb 51 in order to facilitate the location of the transparent cylinder 5 with the sealing means 33.
The inner 59 and outer 61 curbs are spaced by a distance that is slightly greater than the transparent cylinder wall thickness. In this way, the transparent cylinder 5 abuts either one of the inner 59 and outer 61 curbs depending on the ambient temperature and any consequential expansion or contraction of the dish 9.
Figure 7a is a plan view of a top surface of the stripper plate 8. The stripper plate 8 is provided with three apertures 63 which allow the blades 23 to be loosely located therewith in.
Towards the centre of the plate 8, there is provided the blade alignment means 31. The blade alignment means 31 comprises a number of members 65 arranged in a circle about the centre of the plate 8. Each member 65 is of a substantially triangular section and abuts an aperture 63 on either side.
In this way, the blades 23 will be encouraged to enter the apertures 63 if the device is assembled and actuated when the blades 23 are slightly out of alignment with the stripper apertures 63.
Figure 7b is a cross sectional view along the line I---I of figure 7a and gives an indication of the shape of each member 65 of the blade alignment means 31.
For optimum performance, there are twice as many blade alignment means members 65 as blades 23 and apertures 63.
However, a fewer number of alignment members 65 may be provided if desired.
It will be understood, of course, that various modifications may be made to the device disclosed herein without departing from the scope of the appended claims.
For example, preferably the various pieces of the device are "snap-f itted" together, but the pieces may be joined together by a ridge and groove system or other known means.
