A food preparation board

Technical Field of the Invention

The present invention relates to food preparation boards, such as chopping or cutting boards. More particularly, the present invention relates to non-slip chopping or 5 cutting boards for commercial use.

Background to the Invention

Food preparation boards, on which a variety of foodstuffs are prepared, are well known. In particular, chopping or cutting boards, on which food is chopped, cut or otherwise made into smaller pieces, are routinely used in both domestic and commercial environments. Chopping or cutting boards usually comprise front and back surfaces, both surfaces being suitable for the preparation of food stuffs, and are often rectangular in shape.

The worktop surfaces upon which food preparation boards are usually placed for domestic use are often wooden, laminate or stone. This can create a problems 15 relating to the board slipping during use, which both makes the preparation of foodstuffs more difficult and is a health and safety risk, as a potentially moving board may be used in conjunction with very sharp utensils. To counteract this problem, boards for domestic use are sometimes fitted with non-slip rubber or silicone edges, corners, or feet.

In commercial use, food preparation surfaces are often metal, and so the same problem of chopping boards slipping during use is prevalent. The non-slip rubber or silicone edges, comers or feet solution for domestic use chopping boards cannot be used effectively in commercial food preparation as such materials and components may not reach strict hygiene standards and may not be durable enough for commercial use.

Current non-slip solutions for commercial use food preparation boards include very basic techniques such as placing non-slip mats, tea towels or other materials 5 between the worktop surface and the boards, but this can be unhygienic, time-wasting and not cost effective.

Commercial food preparation areas, including hotel and restaurant kitchens, have extremely high hygiene, health and safety requirements, and it would be advantageous to provide food preparation boards which can be securely placed on surfaces in such food preparation areas, whilst complying with all relevant hygiene, health and safety requirements.

It is therefore an aim of embodiments of the present invention to provide an improved food preparation board, which at least partially overcomes and/or alleviates the above problems.

Detailed Description of the Invention

In order that the invention may be more clearly understood, embodiments thereof 15 will now be described, by way of example only, with reference to the accompanying drawings, of which:

Figure 1 is a perspective view from above of a first embodiment of a food preparation board of the invention;

Figure 2 is a perspective view from above of a second embodiment of a food 20 preparation board of the invention;

Figure 3 is a perspective view from above of a third embodiment of a food preparation board of the invention;

Figure 4 is a perspective view from above of a fourth embodiment of a food preparation board of the invention;

Figure 5 is a top down view of the food preparation board of the invention of

Figure 1;

Figure 6 is a side cross sectional view into a corner of the food preparation board of the embodiment shown in Figure 1 and Figure 5;

Figure 7 is a perspective view from above of a fifth embodiment of a food preparation board of the invention; and

Figure 8 is a side perspective view of the food preparation board of the embodiment shown in Figure 1.

Referring firstly to Figures 1, 5 and 6, a first embodiment of a food preparation board of the first, second and third aspects of the invention comprises a solid quadrilateral board 2 having a front surface 4 and rear surface 6. Embedded within the board 2 are four groups of magnets 8, 10, 12, 14. The groups of magnets 8, 10, 12, 14 are located at the four corners, 5, 5’, 5”, 5”’ of the quadrilateral board 2. Each of the groups of magnets 8, 10, 12, 14 consists of two layers of magnets, a lower magnet layer 16 and an upper magnet layer 18, as shown in Figure 6. The lower magnet layer 16 and upper magnet layer 18 are separated by a steel spacing element in the form of a steel spacing sheet 20. The lower magnet layer consists of four lower magnets 22, 22’, 22”,

22’”, in series, with opposing poles of adjacent magnets adjacent to each other. The four lower magnets, 22, 22’, 22” and 22’” are separated by high density polyethylene (HDPE) spacing elements 26, 26’ and 26”. The upper magnet layer 18 similarly consists of four upper magnets, 24, 24’, 24”, 24’” separated by spacing elements in the form of HDPE spacing elements 28, 28’, 28”. The steel spacing element 20 is Lshaped, extending along the edges of each comer 5, 5’, 5” and 5’” of the board 2. Each of the lower magnet layer 16 and upper magnet layer 18 is similarly formed in an Lshape below and above the steel spacing element 20. In particular, the lower magnets 5 22, 22’ and the upper magnets 24, 24’ form one arm of the L-shape, and the lower magnets 22”, 22’” and the upper magnets 24”, 24’” form the other arm of the Lshape. Thus, in this way the lower magnet layer 16 and upper magnet layer 18 form arms consisting of groups of magnets extending along the edges of the corners 5, 5’,

5” and 5’” of the board 2, as shown in figures 1 and 5.

The board 2 is formed by moulding high density polyethylene in a quadrilateral sheet about the magnet groups 8, 10, 12, 14. Magnet groups 8, 10, 12, 14 are fully enclosed within the board and do not extend into the faces of, or protrude through either the front surface 4 or rear surface 6 of the board 2. In this way, the magnet groups 8, 10, 12, 14 are not accessible to micro-organisms which may otherwise render the board

2 unhygienic and/or unsafe for food preparation use.

As can be seen in figure 8, the lower magnet layer 16 extends to within a short distance from the back surface 6, while the upper magnet layer 18 extends to within a short distance from the front surface 4. The steel spacing element extends approximately equidistant between the front surface 4 and back surface 6. In this way, the magnets extend almost to the front surface 4 and rear surface 6, enabling the magnet field produced by the magnet groups 8, 10, 12, 14 to extend to a maximum extent outside of the board 2. In addition, as illustrated in figure 6, the lower magnets 22, 22’, 22”, 22’” and the upper magnets 24, 24’, 24”, 24’” are in series, but spaced apart by spacer elements 26, 26’, 26”, 28, 28’, 28”. The series of magnets separated by spacing elements is believed to enhance the magnetic field so that, in use, when the board 2 is placed on a magnetic surface such as a steel table or food preparation surface, the attraction between the board 2 and the magnetic preparation surface is maximised, and slippage of the board 2 is avoided or significantly mitigated. The magnet groups 8 and

14 are in diagonally opposite comers 5, 5” of the board 2, whilst the magnet groups 10, are located at the other diagonally opposite corners 5’, 5”’. The location of the magnet groups 8, 10, 12, 14 in all four comers 5, 5’, 5”, 5”’ ensures maximum magnetic adhesion of the board to any suitable magnetic surface. On the other hand, as the magnets are located entirely within the board at the comers only, steel chopping or cutting implements being used in or around the centre of the board should not be affected significantly by the magnetic attraction of any of the magnet groups 8, 10, 12,

14.

Similarly, the arrangement of each of magnet groups 8, 10, 12, 14 having two arms 30, 32, with each arm extending along a side of the board 2 ensures that there are magnets located at all sides of the board 2, again enhancing the magnetic strength of the board and its ability to clamp to a magnetic surface without slipping.

Figure 8 illustrates a side perspective view of the food preparation board 2 of Figure 1. As illustrated by Figure 8, the magnets of the upper magnet layer 18 do not extend up to, or protrude above, the front surface of the board 4. Similarly, the magnets of the lower magnet layer 16 do extend up to, or protrude from, the rear surface 6. Figure 8 further illustrates that magnets from neither magnet layer, nor the steel spacing sheet 20, protrude from any surface of the board 2.

Figure 2 illustrates a second embodiment of a food preparation board 102 of the first and second aspects of the invention. The board 102 includes a front surface 104 and a back surface 106. The board 102 is quadrilateral in shape and includes four corners 5, 5’, 5”, 5”’. In the board 102 of Figure 2, two groups of magnets 112 and

114 are located extending along opposite sides of the board 102. The two groups of magnets 112 and 114 consist of two layers of four magnets in series, each magnet in each layer being separated by a HDPE spacing element identical to that between each magnet of the board 2 of Figure 1. Similarly, each layer of the groups of magnets 112 and 114 is separated from the other layer by a steel spacing element similar to the steel spacing element 20 of the board 2 of Figure 1. In this embodiment the groups of magnets 112, 114 extend from the centre point of opposite sides of the board 102 towards the corners of the board. In this configuration, the groups of magnets 112, 114 enable strong clamping of the board 102 to any suitable magnetic surface with minimal slippage. As with the board 2 of Figure 1, as each magnet in the groups of magnets 15 112, 114 are in series, it is believed that this enhances the magnetic field increasing the magnetic strength of the groups of magnets 112, 114.

Figure 3 illustrates a third embodiment of a food preparation board 202 of the first and third aspects of the invention. The board 202 includes a front surface 204 and a rear surface 206 in a quadrilateral shape, having four corners 5, 5’, 5” and 5”’.

Focated in each of the comers 5, 5’, 5”, 5”’ is a single magnet 208, 210, 212 and 214 respectively. Each of these magnets 208, 210, 212 and 214 are entirely enclosed within the board 202, and do not protrude into or out of the front surface 204 or back surface

206.

Figure 4 illustrates a fourth embodiment of a food preparation board 304 of the first aspect of the invention. The board 304 is identical to the board 206 of Figure 3, save that it includes four cuboid comer magnets 308, 310, 312, 314, rather than cylindrical corner magnets of Figure 3.

Each of the boards 2, 102, 202, 302 are shown as transparent in the embodiments shown in Figures 1 to 6, but may also be opaque, or translucent.

Figure 7 illustrates a fifth embodiment of a food preparation board 404 of the first, second and third aspects of the invention. The board 404 includes a front surface 404 and a rear surface 406 in a quadrilateral shape, having four corners 5, 5’, 5” and

5”’. Focated in each of the corners 5, 5’, 5”, 5”’ is a group of magnets 408, 410, 412 and 414 respectively. The four magnet groups 408, 410, 412 and 414 comprise two layers of four magnets in series. Each of the four groups of magnets 408, 410, 412 and 414 is arranged to have two arms extending along edges of the board 402.

The above embodiments are described by way of example only. Many variations are possible without departing from the scope of the invention as defined in the appended claims.
