Description
Vis à filetage coupant. Cutting thread screw.
La présente invention concerne une vis à filetage coupant et elle a trait, plus particulièrement, à une vis perfectionnée à filetage coupant qui comporte une tige et une te te formée à une première des extrémités de cette tige et une partie bout formée à la seconde extrémité de cette dernière, une partie filetée étant définie dans la périphérie extérieure de la tige et la partie filetée comprenant une pluralité de dents coupantes qui y sont formées. The present invention relates to a screw with a cutting thread and it relates, more particularly, to an improved screw with a cutting thread which comprises a rod and a te formed at a first end of this rod and a tip part formed at the second end. of the latter, a threaded portion being defined in the outer periphery of the rod and the threaded portion comprising a plurality of cutting teeth formed therein.
Une vis classique à filetage coupant est composée d'une tige et d'une tête qui est formée à une des extrémités de la tige, l'autre extrémité de la tige étant une extrémité à pointe acérée pour pénétrer dans un objet destiné à recevoir la vis. La tige comporte dans la périphérie extérieure une partie qui est filetée de manière telle que, lorsque l'on visse la vis dans l'objet, la partie filetée se visse sans jeu dans la matière de l'objet et ceci crée une résistance à l'avancement de la vis dans l'objet. ll faut donc que la personne qui effectue le vissage déploie une force plus grande pour visser la vis complètement dans l'objet. A conventional screw with a cutting thread is composed of a rod and a head which is formed at one end of the rod, the other end of the rod being a sharp-pointed end for penetrating an object intended to receive the screw. The rod has in the outer periphery a part which is threaded in such a way that, when the screw is screwed into the object, the threaded part is screwed without play in the material of the object and this creates resistance to the advancement of the screw in the object. It is therefore necessary that the person performing the screwing exert a greater force to screw the screw completely into the object.
La présente invention vise à fournir une vis perfectionnée dont la partie filetée comporte des dents coupantes qui y sont formées pour faciliter le vissage de la vis afin d'atténuer et/ou d'éliminer les inconvénients précités. The present invention aims to provide an improved screw whose threaded part comprises cutting teeth which are formed therein to facilitate the screwing of the screw in order to reduce and / or eliminate the abovementioned drawbacks.
La présente invention fournit une vis qui comprend une tige et une tête formée dans une première extrémité de cette tige et la seconde extrémité de cette dernière est une extrémité à pointe acérée. The present invention provides a screw which comprises a rod and a head formed in a first end of this rod and the second end of the latter is a sharp point end.
La tige comporte une partie filetée définie dans la périphérie extérieu re de cette dernière, la partie filetée comportant au moins une portion sur laquelle une multiplicité de dents sont formées radialement.The rod has a threaded part defined in the outer periphery of the latter, the threaded part comprising at least one portion on which a multiplicity of teeth are formed radially.
Un objectif de la présente invention est de fournir une vis comportant une multiplicité de dents coupantes qui y sont formées de manière que la vis se visse efficacement dans un objet. It is an object of the present invention to provide a screw having a multiplicity of cutting teeth formed therein so that the screw is effectively screwed into an object.
D'autres objectifs, avantages et nouvelles caractéristiques de l'invention apparaîtront à la lecture de la description détaillée donnée ci-après et pour laquelle on se reportera aux dessins annexés;, sur lesquels:
la figure 1 est une vue en perspective d'une vis selon la présente invention;
la figure 2 est une vue illustrative de la vis sur le point d'être vissée dans du bois;
la figure 3 est une vue en coupe partielle d'une partie filetée de la vis comportant des dents coupantes; et
la figure 4 est une vue en élévation latérale, partiellement en coupe, d'une vis vissée dans du bois.Other objectives, advantages and new features of the invention will appear on reading the detailed description given below and for which reference will be made to the appended drawings ;, on which:
Figure 1 is a perspective view of a screw according to the present invention;
Figure 2 is an illustrative view of the screw about to be screwed into wood;
Figure 3 is a partial sectional view of a threaded portion of the screw having cutting teeth; and
Figure 4 is a side elevational view, partially in section, of a screw screwed into wood.
En se référant aux dessins et tout d'abord aux figures 1 à 3, on voit qu'une vis selon la présente invention comprend, d'une façon générale, une tige 10 et une tête 12 formée dans une première extrémité té de cette tige, la seconde extrémité de la tige 10 étant une extrémité 11 à pointe acérée. La tige 10 comporte une partie filetée 20 définie dans sa partie périphérique, la partie filetée 20 comportant une portion inférieure sur laquelle sont définies radialement une multiplicité de dents coupantes 22. Referring to the drawings and first of all to Figures 1 to 3, it can be seen that a screw according to the present invention generally comprises a rod 10 and a head 12 formed in a first tee end of this rod , the second end of the rod 10 being an end 11 with a sharp point. The rod 10 comprises a threaded part 20 defined in its peripheral part, the threaded part 20 comprising a lower portion on which a multiplicity of cutting teeth 22 are defined radially.
En se référant maintenant à la figure 4, on voit que les dents coupantes 22 mordent dans une pièce de bois 30 dans laquelle on visse la vis. Par conséquent, quand une personne (non représentée) visse la vis, les dents coupantes 22 mordent efficacement dans le bois en facilitant un vissage efficace de la vis dans le bois 30 tandis que la partie filetée ne comportant pas de dents coupantes 22 s'engage sans jeu dans le bois 30, ce qui fait que la vis peut facilement être vissée dans le bois 30 et y être solidement implantée. Referring now to FIG. 4, it can be seen that the cutting teeth 22 bite into a piece of wood 30 in which the screw is screwed. Consequently, when a person (not shown) screws the screw, the cutting teeth 22 effectively bite into the wood by facilitating efficient screwing of the screw into the wood 30 while the threaded portion not comprising cutting teeth 22 engages without play in the wood 30, which means that the screw can easily be screwed into the wood 30 and be firmly implanted there.
Cette vis procure donc un avantage effectif quand on la visse dans le bois 30. La configuration, c'est-à-dire l'arrangement, des dents coupantes peut être conçue de manière à satisfaire les exigences propres à des situations différentes. This screw therefore provides an effective advantage when it is screwed into the wood 30. The configuration, that is to say the arrangement, of the cutting teeth can be designed so as to meet the requirements specific to different situations.
I1 est bien entendu que la description qui précède n'a été donnée qu'à titre purement illustratif et non limitatif et que des variantes et des modifications peuvent y être apportées sans sortir du cadre de la présente invention. It is understood that the foregoing description has been given purely by way of non-limiting illustration and that variants and modifications may be made thereto without departing from the scope of the present invention.
