Definitions
- the invention is in the field of cutlery, and it relates to a relief of a sharp tool blade, especially a knife.
- microdentures which are composed of a plurality of curved surfaces with parallel generators, called microbevels, defining with one from the lateral faces of the blade a plurality of respective micro-cutting edges 0.
- microdentures formed by a plurality of short microbevels formed along the blade
- short microtrenchers obtained form a toothing which induces shredding of the material to be cut, the tool thereby relatively sharp, and ultimately being of delicate use when the material, meat in particular, is flexible.
- the designers' efforts have focused on the development of a microdenture made up of short microbevels and long microbevels which alternate in succession, the first shredding the material while the second slices it .
- the blade has along its other 5 face a bevel to reinforce its sharpness.
- Tools which include a micro-denture made up of a plurality of successive short microsharves formed by short microbevels respectively arranged opposite each other on the faces. side of the blade, to give the tool natural stability when in use.
- the object of the invention is to propose a relief, of the microdenture type, for a sharp tool blade, knife in particular, which remedies the abovementioned problems by giving the tool optimal cutting performance and a rigorous natural balance during its use.
- each of said cutting spaces comprises short microbevels and at least one long microbevel formed respectively on either side of the blade wire.
- a relief of a cutting tool blade, knife in particular, of the type of relief, called microdenture, composed of a plurality of curved surfaces with parallel generatrices, said surfaces, called microbevels, defining with one of the lateral faces of the blade a fraction of its wire, called microtrench, more or less long depending on the shape of the directing surface, the relief comprising at least two distinct types of microbevels, depending on the length of the microtrancers that they define, succeeding each other alternately, is mainly characterized in that it is composed of a plurality of micro-cutting edges formed by a plurality of short microbevels making up a so-called short microbevel range, alternating with at least one long microbevel, forming a so-called long microbevel range, and in that said short and long microbevel ranges are provided on each of the lateral faces of the blade, so te that the microdenture formed along the blade is composed of a plurality of successive spaces, called cutting,
- At least a portion of a microbevel along one side face of the blade corresponds to a plurality of short microbevels of the other side face of the blade, the alternation of the plurality of short microbevels with at least one long microbevel formed on one of the faces of the blade being offset with respect to an alternation of a plurality of short microbevels with at least a portion of a long microbevel arranged on the other face of the blade, said alternations being able to be either the same or different, so that the same cutting space comprises respectively on either side of the blade wire a plurality of short microbevels and at least one portion of a long microbevel.
- a plurality of short microbevels formed on one of the faces of the blade can correspond on the other face of the blade, either the same plurality of short microbevels, or at least one long microbevel, or a portion of '' a long microbevel, that is to say a plurality of short microbevels and at least a portion of a long microbevel, and that the successive alternations of long microbevels and short microbevels formed on one of the faces may be, relative to those arranged on the other face of the blade, either identical or different, and either facing or offset.
- Fig.l is a view of a blade provided with a microdenture according to the prior art
- Fig.2 to 8 are details of the edge of a blade provided with a relief according to different respective and preferred embodiments of the invention.
- a knife blade is provided on one of its faces 2 with a microdenture extending along its wire, the said microdenture being composed of distinct and alternating microbevels 4 and 6 of different length, which define with the face 2 of the blade a plurality of micro-cutting edges 8 and 10 of respective length.
- FIGS. 2 to 8 there are various possibilities for executing a relief of the invention.
- the median longitudinal axis A represents an axis of turning of the blade, the two views on either side of this axis illustrating a respective face of the latter.
- the blade comprises, arranged on each of its lateral faces 2 and 12, a succession of microbevels 4,6 and 5,7 alternated of different length, that is to say short and long.
- the areas P of short microbevels and long microbevel are preferably offset from one face to the other, as illustrated in FIGS. 2 to 7.
- the microbevel areas P protrude from the general orientation of the blade wire, while in figs. 3 and 6, the tracks P are set back with respect to the latter, and that in FIGS. 4,5,7 and 8, the ranges P are aligned. In fig. 5, 7 and 8 the areas P are of identical width, unlike those shown in the other figures.
- a range P of long microbevels 5,4 on one side face of the blade corresponds to a portion P_ of beach with short microbevels 6,7 on the other side face of the blade, unlike the other embodiments of the relief of the invention illustrated, in which a range of long microbevels 4.5 on one side face of the blade corresponds to an equivalent range of short microbevels 6.7 on the other side side of the blade.
- the types of ranges can be of a number greater than two; for example, a long microbevel formed on one of the faces of the blade may correspond to two ranges of short microbevels of different length, or alternatively of short microbevels of different length; in other words, a range of short microbevels can be composed of at least two types of short microbevels of respective and different lengths.
- a range of short microbevels which can itself be composed of short microbevels of different lengths, can correspond to a range of several long microbevels, which can itself be composed of long microbevels of different length.
- the length of the areas P of short microbevels and long microbevels formed on one of the lateral faces of the blade and the length of the areas P of short microbevels and long microbevels formed on the other face of the blade can be either identical or different; in other words, a first alternation of short microbevels and long microbevels formed on one side of the blade corresponds to a second alternation of short microbevels and long microbevels formed on the other face of the blade, the so-called first and second alternation can be either different, or identical, and in the latter case be either facing one another (fig.
