FR2816541A1 - Food slicer with multiple blades held between two plates by struts has blade guide comb constituted by spaced partitions receiving blades which pass through food and platform - Google Patents

Abstract

The food slicer is composed of blades (10) held between two plates (13) by struts (15) and fixed by spindles (14). A blade guide comb (17) is constituted by an assembly of spaced partitions (16) which receive the blades which must pass through the food and the platform (22) releasing the cut slices. The blades are fixed in parallel over several levels (11).

Description

<Desc / Clms Page number 1>

The present invention relates to a knife with multiple blades placed in parallel on several levels for slicing vegetables or other foods: knife operating with a blade-guide comb forming a filtering platform for food support.

The prior art means that:
1) The food is pushed on a single row of several dozen blades which intervene simultaneously, sometimes representing a cumulative thickness of steel of several centimeters difficult to integrate into a hard product (example: carrot, turnip, potato ...)
2) It does not completely eliminate the risk of injury.

 3) The quantity debited at each operation is low and the use of an accessory such as a pusher is binding.

 The present invention is based on a simple logic: the penetration of a single blade at a time into a carrot (or other product) or section of carrot, with the possibility of recoil of the cut parts, requires much less effort than simultaneous penetration many blades.

 According to the invention, the arrangement of the blades in parallel on several levels allows easy penetration of the two blades of the first level which can push the cut pieces outwards. The three blades of the second level will benefit from the same advantage in addition to the empty space created by the passage of the two blades of the first level. The progressive number of blades of the following levels will increase to 6/12/24 respectively; this number cannot be greater than the number of empty recoil spaces previously created by the passage of the blades of the previous levels.

 This arrangement allows cutting in one go and instantly into slices of 3.5 mm thick up to 500 g (+ or-) of hard products safely.

 By way of example (non-limiting) (FIG. 4) device with 47 blades on five levels for slices of 3.5 mm thickness: - the 2 blades of the first level (attack) will be fixed at 56 mm l 'from each other, that is 28 mm on either side of the center line of this level.

- the 3 blades of the 2nd level will also be fixed at 56 mm from each other so that their trajectories pass 28 mm from those of the blades of the 1st level.

- the 6/12/24 blades of the 3/4/5 levels will be fixed respectively at 28/14/7 mm from each other so that their trajectories pass to 14/7/3, 5 mm from those of blades from previous levels.

The blades are fixed between two (inflexible) plates through slots and held outside of the plates by pins (or other methods). The tension of the blades is obtained by spacers which separate the plates from one another.

The movement of the knife brings the blades into contact with food.

The number of blades, their dimensions, the importance of the spaces which separate them (on the same level or between levels), the number of levels, determine the size of the knife and that of the blade guide comb which completes it, as well as the thickness of the slices.

By way of example (nonlimiting): a 47-blade device intended more specifically for restaurateurs will have approximately the following dimensions: height 30 cms, width 16 cms, depth 20 cms, while for individuals the device may possibly only have 30 blades and much smaller dimensions.

The shape of the edge of the blade may be straight or sawtooth, more or less deep and wide. Sharpening and smoothing will be optimum.

The multi-blade knife block is coupled to a blade-guide comb block forming a food support filtering platform.

This blade guide comb is made up of as many hollow intermediate partitions as there are blades. The partitions will be fixed together only at their ends.

They will be separated from each other by mini-dividers, thus creating a space per blade which will ensure the free movement of this blade over the entire height of the comb through the food and the food support filtering platform, freeing all the slices cut.

The space between partitions will be, at least, the thickness of the blade used.

The thickness of the partition will be equal to the thickness of the desired slices minus the space reserved for the blade.

For example, to obtain slices 3.5 mm thick, the space between

 the partitions will be approximately 15110 th of a millimeter for a 10 or 12/10 th blade, with possible room for maneuver of a few tenths. The thickness of the partition will be 20/10 th or 2 millimeters.

The knife blade support plates move by sliding along and outside the comb block using handles.

The knife block can possibly be made of several independent and integral parts, such as interchangeable drawers for various interventions and cutting slices of different numbers and thicknesses. As the spacers and the lower edge of the plates are lower than the blades, safety is ensured.

All the parts of this device being made easily accessible, its maintenance will be easy.

The invention is described below using an example and references to the accompanying drawings in which, Figure 1 shows the multi-blade knife according to the invention.

Figure 2 shows a front of the partitions of a comb.

Figure 3 shows a side assembly of several partitions spaced from each other.

Figure 4 is a general view of the complete device, knife plus comb, according to the invention.

FIG. 1 represents the knife composed of blades (10) fixed in parallel on several levels (11) in an order in accordance with the invention, through slots (12) drilled in support plates (13) and retained by axes (14).

Spacers (15) ensure the tension of the blades (10).

FIG. 2 represents, from the front, a partition (16) and its filtering platform part (22) for food support as well as the location of the housing (21) reserved for food.

Figure 3 shows, from the side, partitions (16) assembled by threaded pins (18)

<Desc / Clms Page number 4>

 to form the blade guide comb (17); mini-spacers (19), provide empty spaces (20) reserved for the circulation of the blades. The total thickness of the partitions (16) combined form a filtering platform (22) supporting the food.

Figure 4 shows the mounting of the blade guide comb coupled with the knife block in the high position.

The partitions can be made either of hard food plastic in a single injection molding operation, or of food aluminum by stamping.

Claims (5)

CLAIMS 1) Knife with multiple blades for slicing vegetables and various foods comprising blades (10) stretched in parallel by spacers (15) between two plates (13) pierced with slots (12) to receive the blades (10) which will be retained at the outside of the plates by pins (14), and a blade guide comb (17) made up of intermediate partitions (16) forming a filtering platform (22) for food support, housing (21) and spaces (20) for movement of the blades (10) characterized in that the blades (10) are arranged on several levels (11) in a specific order of intervention according to the invention. 2) Device according to claim 1 characterized in that the spaces (20) between the partitions allow the blades (10) to pass through the food and the platform (22) filtering food support. 3) Device according to claim 1 characterized in that the penetration of a single blade per section of food must be facilitated by the prior existence of its empty space created by the passage of a blade from a previous level, the empty space favoring the recoil of the cut parts. 4) Device according to any one of the preceding claims, characterized in that the number of blades (10), their dimensions, the importance of the spaces which separate them (on the same level or between levels) (11) the number of levels , determine the size of the knife and comb as well as the thickness of the slices. 5) The knife block can be made of several independent and integral parts, such as interchangeable drawers, for diversified or partial interventions to obtain slices of different numbers and thicknesses.
