Definitions
- the invention relates to the technical sector of sharp instruments of the knife type, comprising a fixed blade secured to a handle.
- the invention relates to knives for professional use for cutting various products. This is the case in particular for knives used in the food industry, for example for slaughtering, cutting meat ... Obviously, household knives for cutting meat or others, come in in the context of the invention.
- the knife has, in a perfectly known manner, a sharp blade made integral with a grip handle of suitable ergonomic shape.
- the blade is most often made of treated stainless steel while the handle can be made of different materials such as wood, plastics ...
- the blade has different profiles, on the one hand, and different arrangements for making the cut as such, on the other hand.
- these knives do not offer sufficient safety for the user, if we consider certain working conditions. Often the user is obliged not only to exert a support force directed from top to bottom to make the cut, but also a push force at the level of the handle, in order to make penetrate the blade into the product to be worked. This results in significant risks of slipping of the hand, which under the pushing force considered, can escape the handle and slide at the edge of the blade. More or less serious cuts therefore exist with sometimes the cutting of the ligaments.
- Some knife handles have in their connection part with the blade, a heel which in some cases can act as a stopper in the hand of the user but which cannot, in any case, prevent him from sliding at the cutting edge of the blade. In other words, protection is not guaranteed.
- This state of the art can be illustrated by the teaching of patents GB 2171628 and EP 0283445.
- the problem which the invention proposes to solve is to be able to ensure in a simple, safe, effective and rational manner the protection of the fingers of the hand of the user holding the handle of the knife by eliminating any risk of slipping of the hand at the level the edge of the blade. It also appeared important to take into account the problem of positioning the cutting edge of the blade which must be as low as possible relative to a work plan considered. It is understood that the dimensions of the blade in particular in terms of its length and its thickness and its height are dictated by standards which depend directly on the nature of the work to be performed.
- a cutting instrument of the type of those comprising in a known manner a fixed blade secured to a handle, which has, on the side of its part of connection with the blade, arrangements capable of ensuring the protection of the user's fingers, with respect to the cutting edge of said blade.
- the problem posed of the safe and effective protection of the user's fingers is solved in that the arrangements of the handle are constituted by a curved profile formed very substantially in the thickness and the extension of the connecting part of the handle with the blade. by forming a curved part in a direction opposite to the blade in the form of a substantially C to protect about two fingers.
- the profile delimits an internal loop open in very substantially of a C, said profile having, on the outside, a straight segment extending substantially parallel to the upper straight edge of the handle, being connected to the part of the handle, by a rectilinear segment arranged angularly, in order to allow the 'user always tilt the blade relative to a work plan considered, in order to have a sufficient length of contact, at the cutting edge.
- either the curved profile is located on the edge of the blade or on the back of the blade.
- the blade is lowered and inclined relative to the upper edge of the handle so as to position the cutting edge of said blade as close as possible to a plane. of work.
- the connection angle of the blade relative to the handle is between 5 ° and 25 ° approximately.
- the connection angle of the blade is preferably 10 °.
- the whole handle and the curved protective profile are obtained by injection of a plastic material.
- FIG. 1 is a front view of an exemplary embodiment of a cutting knife according to the prior art.
- FIG. 2 is a view corresponding to Figure 1, showing the same type of knife as that illustrated in Figure 1 and executed according to the features of the invention.
- FIG. 3 is a view corresponding to line 3.3 of Figure 2.
- FIG. 4 is a front view showing another type of knife according to the features of the invention.
- the knife comprises a blade (1) made integral with a handle (2).
- the blade (1) is made integral with the handle (2) by any known and appropriate means with a fixed angular position, so as to constitute a non-foldable knife.
- the handle (2) has, on the side of its connection part (2a) with the blade (1), a curved profile (2b) acting as an open guard capable of protect the user's fingers.
- the profile (2b) is formed very substantially in the thickness and the extension of the connection part (2a) of the handle with the blade.
- the profile (2b) delimits an internal loop (2bl) open in the form very substantially of a C.
- the curved profile (2b) has a rectilinear segment (2b2) extending substantially parallel to the upper rectilinear field (2c ) of the handle.
- This rectilinear segment (2b2) is connected to the part (2a) of the handle, by a rectilinear segment (2b3) arranged angularly, in order to allow the user to always tilt the blade relative to a considered work plane, in order to 'have a sufficient length of contact, at the cutting part (lb) of said blade.
- the whole of the blade (1) is lowered relative to the upper edge (2c) of the handle (2).
- the connection angle of the blade (1) relative to the handle (2) is between 5 and 25 °.
- this angle is preferably 10 °.
- the invention applies to all types of knife blades (straight or curved) ( Figures 2 and 4) depending on the desired applications.
- the blade can have any cutting and cutting profiles (lb).
- the blade as such therefore remains produced in the known manner in terms of shapes, dimensions and characteristics. Only its positioning relative to the handle is modified, on the one hand in height and, on the other hand, in inclination.
- the assembly of the handle (2) and of the curved protective profile is advantageously obtained by injection of a plastic material.
- the invention finds an application to all types of knives, in particular those used in the food industry, for slaughtering, cutting meat, as well as for cutting certain vegetables such as salad, cauliflower , without excluding other applications of the household type.
- the protective profile can be located depending on the intended applications, on the side of the back of the blade or both on the side of the cutting edge and the back of the blade.
