Definitions
- the present invention relates to a knife, the handle of which is coated with an elastomer.
- a knife is known in particular from FR-A-2,541,919, which served for the preparation of the preamble of claim 1.
- This knife is in particular intended for professional uses, in particular uses having a character of continuity or semi-continuity over time.
- the invention relates to a knife as claimed in claim 1.
- the elastomer to be used for coating the handle of the knife must be of a type which is capable of adequately absorbing the shocks to which the knife may be subjected, which offers good resistance to sliding even in contact with fatty substances, which is unassailable by conventional detergents, and which is capable of withstanding at temperatures of at least 120 degrees.
- elastomer a synthetic rubber based on styrene-butadiene (Buna), or based on ethylene-propylene, or based on polyacrylic esters, or even thermoplastic elastomers based on polyesters. -poly- ethers.
- the above-mentioned elastomers are, inter alia, capable of being perfectly welded to the plastic material, preferably of an impact-absorbing type (belonging to the class of polyamides, for example), in which the tail of the knife blade is embedded .
- the knife forming the object of the present invention and which is shown according to the preferred embodiment in the accompanying drawings, comprises a sharp blade 1 (of hardened steel or stainless steel, for example) and a shank 2, connected to the said blade, the tail of which is embedded and supported by a coating 3 of artificial plastic material which, in turn, is covered with a layer of elastomer 4.
- a sharp blade 1 of hardened steel or stainless steel, for example
- a shank 2 connected to the said blade, the tail of which is embedded and supported by a coating 3 of artificial plastic material which, in turn, is covered with a layer of elastomer 4.
- the said elastomer layer is interrupted in an anterior region 5, and in an intermediate region 6 of the handle, this to allow the coating of artificial plastic material to be inserted (in the production phase) in the said regions, until reaching the level of the outer face of the elastomer layer.
- This constructive feature makes it possible, among other things, to anchor said elastic layer securely to the coating of rigid plastic which serves to support the tail 2 of the blade 1.

Description
La présent invention concerne un couteau dont le manche est revêtu d'un élastomère. Un tel couteau est connu notamment de FR-A-2 541 919, qui a servi pour l'élaboration du préambule de la revendication 1.The present invention relates to a knife, the handle of which is coated with an elastomer. Such a knife is known in particular from FR-A-2,541,919, which served for the preparation of the preamble of claim 1.
Ce couteau est en particulier destiné à des usages professionnels, notamment usages ayant un caractère de continuité ou de semi-continuité dans le temps.This knife is in particular intended for professional uses, in particular uses having a character of continuity or semi-continuity over time.
L'invention concerne un couteau comme revendiqué dans la revendication 1. Compte tenu du genre d'activité que doit déployer une personne ayant l'intention de se servir du couteau selon l'invention, l'élastomère à utiliser pour revêtir le manche du couteau devra être d'un type qui est capable d'amortir convenablement les chocs auxquels le couteau peut être assujetti, qui oppose une bonne résistance au glissement même au contact de substances grasses, qui est inattaquable par les détergents usuels, et qui est susceptible de résister à des températures au moins de 120 degrés. Ainsi, à titre d'exemple, on pourra avantageusement utiliser comme élastomère un caoutchouc synthétique à base styrène-butadiène (Buna), ou à base ethylène-propylène, ou à base d'esters polyacryliques, ou même des élastomères thermoplastiques à base de polyesters-poly- éthers.The invention relates to a knife as claimed in claim 1. Taking into account the kind of activity which a person intending to use the knife according to the invention must deploy, the elastomer to be used for coating the handle of the knife must be of a type which is capable of adequately absorbing the shocks to which the knife may be subjected, which offers good resistance to sliding even in contact with fatty substances, which is unassailable by conventional detergents, and which is capable of withstanding at temperatures of at least 120 degrees. Thus, by way of example, it is advantageously possible to use as elastomer a synthetic rubber based on styrene-butadiene (Buna), or based on ethylene-propylene, or based on polyacrylic esters, or even thermoplastic elastomers based on polyesters. -poly- ethers.
Les élastomères susmentionnés sont, entre autres, capables de se souder parfaitement à la matière plastique, de préférence d'un type amortissant les chocs (appartenant à la classe des polyamides, par exemple), dans laquelle la queue de la lame de couteau est noyée.The above-mentioned elastomers are, inter alia, capable of being perfectly welded to the plastic material, preferably of an impact-absorbing type (belonging to the class of polyamides, for example), in which the tail of the knife blade is embedded .
Le couteau à manche revêtu d'un élastomère qui fait l'objet de la présente invention est décrit plus en détail ci après en relation à l'un de ses modes d'exécution préféré pour la compréhension duquel on se référera au dessin dont:
- - La figure 1 est une vue de côté du couteau selon l'invention;
- - La figure 2 en est une vue en coupe suivant la ligne A-A de figure 1; et
- - La figure 3 est une vue en coupe suivant la ligne B-B de figure 2.
- - Figure 1 is a side view of the knife according to the invention;
- - Figure 2 is a sectional view along the line AA of Figure 1; and
- - Figure 3 is a sectional view along line BB of Figure 2.
Le couteau formant l'objet de la présente invention et qui est représenté selon le mode préféré d'éxecution sur les dessins annexés, comprend une lame tranchante 1 (en acier trempé ou en acier inoxydable, par exemple) et une queue 2, reliée à la dite lame, la quelle queue est noyée et supportée par un revêtement 3 en matière plastique artificielle qui, à son tour, est recouvert d'une couche d'élastomère 4.The knife forming the object of the present invention and which is shown according to the preferred embodiment in the accompanying drawings, comprises a sharp blade 1 (of hardened steel or stainless steel, for example) and a
Comme on le constate facilement de l'examen des figures du dessin, la dite couche d'élastomère est interrompue dans une région antérieure 5, et dans une région intermédiaire 6 du manche, ceci pour permettre au revêtement de matière plastique artificielle de s'insérer (en phase de production) dans les dites régions, jusqu'à gagner le niveau de la face extérieure de la couche d'élastomère.As can easily be seen from the examination of the drawing figures, the said elastomer layer is interrupted in an
Cette particularité constructive permet, entre autres choses, d'ancrer solidement la dite couche élastique au revêtement de matière plastique rigide qui sert de support à la queue 2 de la lame 1.This constructive feature makes it possible, among other things, to anchor said elastic layer securely to the coating of rigid plastic which serves to support the
Il est évident que la forme et les dimensions de la lame tranchante et du manche précités sont des caractéristiques ne rentrant pas dans le domaine de l'invention.It is obvious that the shape and the dimensions of the aforementioned sharp blade and of the handle are characteristics which do not come within the scope of the invention.
Claims (1)
- Knife appointed to professional use, including a cutting blade (1) as well as a blade tang (2) which is connected with the same blade, wherein this tang is dipped in a supporting embedding (3) made of plastic artificial material, which is likewise covered by an elastomeric layer (4), characterized by the fact that the aforesaid layer in at least an anterior zone (5) and in an intermediate zone (6) of the handle is interrupted, in order to allow that the embedding made of plastic artificial material can be inserted (during the manufacturing process) into the aforesaid zones until to reach the level of the external surface of the said covering layer; whereas this practical realization allows that the elastomeric layer (4) can be steadily anchored to the embedding made of plastic material (3) which performs a function of support for the tang (2) connected with the cutting blade (1 ).
