CUTTING SYSTEM HAVING MEANS FOR LOCKING A KNIFE BLADE IN A HOUSING FORMED IN A CUTTING BOARD

1. Field of the invention

The invention relates to the field of kitchen utensils.

More specifically, the invention relates to a cutting system comprising a cutting board and a knife.

2. State of the art

When you want to cut bread, it is common to waste time looking for both a cutting board and a knife.

Document CA1025333 discloses a cutting board having a housing for clipping the handle of a knife. Thanks to this housing, the board and the knife can be easily moved together and no longer waste time searching for the knife.

However, this known technique has the disadvantage of being dangerous for the user when he manipulates the board on which the knife is clipped, because the blade of the knife is not protected.

In order to remedy this drawback, it has been thought to form a slit in a cutting board to accommodate the blade of the knife. The document GB410933 and the document GB598944 describe for example a cutting board which has a slot on a longitudinal edge or an oblique slot making it possible to protect the blade of a knife.

A disadvantage of this known technique is that it is necessary to hold both the board and the handle of the knife when one wants to move them together, for example to take them out of a drawer or to store them. Otherwise, the knife may fall and cause damage or injury.

3. Objectives of the invention

The invention therefore particularly aims to overcome the drawbacks of the prior art mentioned above.

More specifically, the invention aims to provide a cutting system that is easy to handle.

An object of the invention is also to provide a cutting system for protecting the blade of a knife.

Another objective of the invention is to provide a cutting system which is simple to manufacture, and of reduced cost price.

An objective of the invention is also to propose a cutting system which is easy to store.

Another objective of the invention is to provide a cutting system which is reliable and secure for the user.

4. Statement of the invention

These objectives, as well as others, which will appear subsequently, are achieved using a cutting system comprising a knife having a handle and at least one blade and a cutting board suitable for food contact, said board having a housing opening onto an edge of said board configured to receive said blade of said knife through its opening.

It should be noted that in the context of the invention, the cutting board can be made of any material suitable for suitable food contact, such as beech, PVC, HDPE, Corian (registered trademark), or bamboo.

According to the invention, such a cutting system comprises means for magnetic locking of said blade in said housing, and in that the end of said handle turned towards said blade has a width or a thickness greater than the length and / or the width of said opening, so that said handle protrudes from said edge of said board to form a handle for manipulating said cutting system

Thus, in a new way, the invention proposes to use the handle of the knife as a handle of the cutting system, when the blade of the knife is stored in the body of the cutting board.

Furthermore, one can easily manipulate this cutting system using the handle to store it for example, because the board is not likely to separate from the knife, due to the locking. In addition, the knife with the blade stored in the body of the board. Thus, on the one hand, the blade is protected from shocks, on the other hand, the user is protected from the risk of cutting. In addition, the assembly thus formed is lighter, because the handle of the knife serves as a handle for manipulating the cutting system. Finally, such a cutting system requires less material to manufacture. It is therefore less expensive.

According to particular embodiments, the cutting system, object of the invention, has one or more of the following characteristics, according to any operating technical combination.

According to one embodiment of the invention, said blade is at least partially metallic and said magnetic locking means are arranged so as to act on said blade.

According to one embodiment of the invention, said magnetic locking means are arranged so as to act with a part made of ferromagnetic material from the end of said handle turned towards said blade.

It is thus easy to insert the knife blade over its entire length in the housing, the locking only taking place when the blade is almost completely inserted in the housing.

According to one embodiment, said magnetic locking means are mounted in said housing, substantially at an end distal from said opening.

Thus, the locking of the knife operates only when the blade of the knife is partly inserted in the housing. The introduction of the knife blade through the opening of the housing is then facilitated.

According to one embodiment of the invention, said housing comprises at least one cavity opening into said housing in which are embedded said magnetic locking means.

Thus, a particularly simple cutting system is obtained.

According to one embodiment of the invention, said magnetic locking means comprise at least one magnet, preferably at least two magnets.

It should be noted that the number and strength of the magnets should be chosen according to the weight of the cutting board.

According to one embodiment of the invention, said magnet is mounted on said board in the vicinity of said opening

According to one embodiment of the invention, the housing is formed by two reservations in two parts of the board, the two parts being assembled along a joint plane along the axial plane of the board.

The manufacturing of the cutting board is thus simplified

According to one embodiment of the invention, said housing is formed in the thickness of said board.

According to one embodiment of the invention, a cutting system as described above comprises means for hooking said cutting system comprising a ring and / or an eyelet.

This cutting system can thus be stored, suspended from a credenza in the kitchen

According to a particular aspect of the invention, said attachment means are secured to the end of said handle opposite to said blade.

Thus, the cutting system can be suspended by the handle, allowing the optimization of space and therefore the organization of the credenza.

According to a particular aspect of the invention, said opening of said housing is formed on an edge of said board.

According to one embodiment of the invention, the edge of which opens the housing is a longitudinal edge of said cutting board.

According to one embodiment of the invention, said edge on which the opening of the housing is formed is a transverse edge of said cutting board.

According to one embodiment of the invention, the cutting board is a bread cutting board.

6. Detailed description of embodiments of the invention

6.1. Example of embodiment of the invention

Illustrated in FIGS. 1a to 1d, an embodiment of a cutting system 100 according to the invention, formed by a cutting board 110 having two substantially parallel working faces and a knife 160.

The board 110 comprises a housing 120 opening onto an edge also called edge 140 of the board 100 by a rectangular opening 130. This housing 120 forms a sheath capable of accommodating a blade 170 of the knife 160.

The knife 160 has a handle 180 whose thickness 181 at the junction with the blade 170 is greater than the width 131 of the opening 130. Thus, the handle 180 of the knife 160 cannot penetrate into the housing 120.

In a variant of this particular embodiment of the invention, provision may be made for the width 182 of the handle at the junction with the blade 170 to be greater than the length 132 of the opening.

When the blade of the knife 160 is retracted into the housing 120 and entirely protected by the latter, the handle 180 projects at the periphery of the board 110 and can advantageously serve as a handle for manipulating the cutting system.

In order to avoid any risk of injury, the blade 170 of the knife 160 is held in the housing 120 in the stowed position by means of the knife locking means (not shown in this figure 1), sized according to the weight of the board 110 .

In FIG. 2, a detail section view of FIG. 1 shows the means for locking the handle 180 of the knife 260 with the board 210.

This locking is ensured by at least one magnet 235 intended to attract a guard 275 of the knife 260 arranged at the end of the handle 280 facing the blade 270.

To allow attraction by the magnet 235, the guard 275 is made of ferromagnetic material. In addition, the magnet 235 is arranged on the edge 240 of the board 210 opposite the guard 275 in the vicinity of the opening 230.

Thus, when the blade 270 of the knife is fully engaged in the sheath 220, the guard 275 of the knife 260 is attracted by the magnets 235 which provide magnetic locking in the stowed position of the knife 260.

In a variant of this particular embodiment of the invention, it can also be envisaged to lock the blade of the knife in the housing.

6.2. Example of a spring support

FIG. 3 illustrates an alternative embodiment of the locking of the knife 360 with the board 310 by pressing on the blade 370.

For this, the board 310 comprises at the opening 330 elastic means, such as spring blades 339. The blade 370 of the knife 360 also has an area 371 whose section is greater than the section of the rest of the blade 370. Thus, when the blade 370 is fully engaged by the opening 330 in the sheath 320, the spring blades 339 pinch the area 371 of the blade 370, which allows the knife to be held firmly in the stowed position.

In addition, the spring blades 339 are arranged along the longitudinal axis of the sheath 320. This orientation facilitates the introduction of the blade 370 of the knife 360 between the spring blades 339. In addition, the insertion of the blade 370 is facilitated by the fact that its section gradually increases. Thus, the pressure effort is progressive. This avoids dangerous jolts for the user when storing or extracting the knife.

According to an alternative embodiment, provision may be made for the spring leaves to be mounted in the sheath in a transverse orientation.

6.3. Example of a friction hold

FIG. 4 illustrates another alternative embodiment of the locking of the knife 460 with the board, by friction between the blade 470 and the opening 430 of the sheath (not shown in FIG. 4). As in the embodiment of FIG. 3, the knife 460 comprises on the blade 470 a zone 471 whose cross section is greater than that of the rest of the blade 470. To ensure the maintenance by friction of the knife 460 in the sheath of the board 410, the thickness 472 of the blade 470 in the area 471 is substantially equal to the width 432 of the opening 430.

Furthermore, in this embodiment, the board 410 comprises a first part 411 incorporating a groove closed by a second part 412 to form a sheath opening out through the opening 430.

6.4. Other examples of embodiment of the invention

FIG. 5a shows another example of an embodiment of a cutting system 500 according to the invention, which is formed by a board 510 and a knife 560, the blade 570 of which is partially represented. engaged by the opening 530 in the sheath 520.

In this view we can also see the position of the locking means 535 disposed substantially at a distance from the opening 530 of the housing 520 and preferably at the bottom of the housing or at a distance from the opening substantially equivalent to the length of the blade 570 knife 560.

As can be seen in the detailed view according to section AA of FIG. 5a illustrated by FIG. 5b, this locking is ensured by two magnets 535 each embedded in a cavity 536 opening into the housing 520. When part of the the end of the blade 570 opposite the handle enters the magnetic field of the magnet 535, in particular to the right of the magnet, it is attracted by that. Thus, the knife 560 is kept locked by the force of attraction of the magnet 535 in the housing 520 of the board 510. It is then possible to take and handle the board 510 by the handle 580.

In FIG. 5b, it can also be seen that the board 510 is formed of two parts 511, 512 assembled along the axial plane of the board, at the interface of which the housing 520 is located. Furthermore, the housing 520 is formed of two reservations 512 present opposite the surface of the joint plane of each of the parts 511, 512. This constructive arrangement facilitates the positioning of each magnet 535 in each cavity 536 before the assembly of the two parts 511, 512.

In addition, the two parts 511, 512 of the board 510 are of substantially equivalent thicknesses so that the knife handle is centered relative to the thickness of the board 510, which facilitates the handling of the cutting system 500 .

In a variant, the accommodation is formed by a single reservation in one of the two assembled parts. The thickness of the two parts forming the board can then be different so as to keep the position of the handle 15 centered with respect to the thickness of the board.
