Description
La présente invention a pour objet un dispositif permettant d'assemblerThe present invention relates to a device for assembling
et/ou 10 de bloquer des éléments mécaniques. Elle s'applique notamment mais non exclusivement à l'assemblage des éléments de construction. and / or blocking mechanical elements. It applies in particular but not exclusively to the assembly of construction elements.
On sait que le moyen le plus couramment utilisé pour assembler deux pièces consiste en une vis filetée comprenant une tête présentant au moins une empreinte afin de permettre de la faire tourner pour exercer sa fonction de vissage par exemple dans une pièce taraudée ou dans une cheville. It is known that the most commonly used means for assembling two parts consists of a threaded screw comprising a head having at least one impression to allow it to rotate to perform its function of screwing for example in a threaded part or in an ankle.
Cependant, l'utilisation d'une telle vis nécessite l'utilisation d'un tournevis afin de la faire tourner dans la susdite pièce taraudée ou dans la susdite cheville, cette opération de vissage pouvant être rendue difficile dans des endroits exigus et difficiles d'accès. However, the use of such a screw requires the use of a screwdriver to rotate it in the said threaded part or in the aforementioned plug, this screwing operation can be made difficult in tight and difficult places of access.
De plus, l'utilisateur devra exercer un couple important afin d'assurer un blocage optimal de la vis dans ladite pièce taraudée ou dans ladite cheville 25 sans pour autant garantir l'absence de jeu entre les parties assemblées. In addition, the user must exert a significant torque to ensure optimal locking of the screw in said threaded part or in said pin 25 without guaranteeing the absence of play between the assembled parts.
Enfin, le dévissage d'une telle vis peut être rendue difficile si elle est rouillée ou si elle avait été serrée très fortement. Finally, the unscrewing of such a screw can be made difficult if it is rusted or if it had been tightened very strongly.
L'invention a donc plus particulièrement pour but de supprimer ces inconvénients en proposant un dispositif permettant de procéder à un vissage et à un dévissage facilement, rapidement et efficacement À cet effet, elle propose un dispositif permettant de visser et de dévisser des pièces mécaniques caractérisé en ce qu'il comprend une vis comprenant: É une tige au moins en partie filetée; É une rondelle au travers de laquelle s'engage ladite vis, ladite rondelle étant destinée à s'interposer entre une pièce d'appui et les pièces mécaniques à visser; É une pièce d'appui à profil de came montée pivotante à l'extrémité supérieure de la tige autour d'un axe perpendiculaire à l'axe longitudinal de ladite vis, cette pièce d'appui étant prolongée par un levier disposé de manière à prendre deux positions, à savoir une première position dans laquelle le levier s'étend sensiblement parallèlement à l'axe de la vis, et la distance de l'axe de pivotement à la zone d'appui de la surface de came rapportée dans l'axe de la vis présente une valeur minimale, et une deuxième position dans laquelle ledit levier s'étend sensiblement perpendiculairement à l'axe de la vis et ladite distance présente une valeur maximum; É une goupille peimettant de maintenir assemblées ladite pièce d'appui et ladite tige. The object of the invention is therefore more particularly to eliminate these drawbacks by proposing a device making it possible to screw and unscrew easily, quickly and efficiently. For this purpose, it proposes a device for screwing and unscrewing mechanical parts characterized in that it comprises a screw comprising: a rod at least partly threaded; A washer through which said screw engages, said washer being intended to be interposed between a support piece and the mechanical parts to be screwed; A cam-shaped support piece pivotably mounted at the upper end of the rod about an axis perpendicular to the longitudinal axis of said screw, this support piece being extended by a lever arranged so as to take two positions, namely a first position in which the lever extends substantially parallel to the axis of the screw, and the distance from the pivot axis to the bearing area of the cam surface reported in the axis the screw has a minimum value, and a second position in which said lever extends substantially perpendicular to the axis of the screw and said distance has a maximum value; É a peimettant pin to maintain assembled said support piece and said rod.
De manière avantageuse, la pièce d'appui est fixée sur la tige partiellement filetée en étant désaxée par rapport à celle - ci, cette disposition permettant d'augmenter le couple exercé sur la pièce d'appui, à la fois pour assurer le vissage de la vis et pour exercer un effort axial de serrage sur les pièces mécaniques à visser lors de la rotation du profil de came de la première à la seconde position. Advantageously, the support piece is fixed on the partially threaded rod being off-axis with respect thereto, this arrangement making it possible to increase the torque exerted on the support piece, both to ensure the screwing of the screw and to exert an axial clamping force on the mechanical parts to be screwed during the rotation of the cam profile from the first to the second position.
Ainsi, pour obtenir la solidarisation de deux pièces au moyen de la vis précédemment décrite, l'opérateur effectue une action de vissage en engendrant une rotation de la vis. Thus, to obtain the joining of two parts by means of the previously described screw, the operator performs a screwing action by generating a rotation of the screw.
Cette action de vissage peut être exécutée sans outillage en utilisant la pièce d'appui dans sa première position. This screwing action can be performed without tools using the support piece in its first position.
En fin de vissage, l'utilisateur doit basculer la pièce d'appui dans sa deuxième position. Au cours de ce basculement la pièce d'appui exerce, en raison de son profil de came, un effort de traction sur la vis et parallèlement un effort de serrage des deux pièces l'une contre l'autre. At the end of screwing, the user must switch the support piece in its second position. During this tilting the support member exerts, due to its cam profile, a tensile force on the screw and parallel a clamping force of the two parts against each other.
Dans le cas où l'on utilise une rondelle déformable élastiquement, cette 10 solution présente l'avantage de régler l'effort de serrage exercé sur les pièces à assembler. In the case where an elastically deformable washer is used, this solution has the advantage of adjusting the clamping force exerted on the parts to be assembled.
Avantageusement, un simple relèvement de la pièce dans sa première position permet de desserrer l'ensemble et facilite le désengagement de la vis. Advantageously, a simple raising of the piece in its first position loosens the assembly and facilitates the disengagement of the screw.
Un mode d'exécution de l'invention sera décrit ci-après, à titre d'exemples non limitatifs, avec référence aux dessins annexés, dans lesquels: La figure 1 est une vue latérale et en perspective d'une vis selon 20 l'invention. An embodiment of the invention will be described below, by way of nonlimiting examples, with reference to the accompanying drawings, in which: FIG. 1 is a side and perspective view of a screw according to FIG. invention.
La figure 2 est une vue postérieure et en perspective d'une vis selon l'invention. Figure 2 is a rear view and in perspective of a screw according to the invention.
La figure 3 est une vue latérale et en perspective d'une vis selon l'invention engagée dans une cheville. Figure 3 is a side view in perspective of a screw according to the invention engaged in an ankle.
La figure 4 est une vue en perspective de la pièce d'appui de la vis selon l'invention en position abaissée. Figure 4 is a perspective view of the support piece of the screw according to the invention in the lowered position.
La figure 5 est une vue en perspective de la pièce d'appui de la vis selon l'invention en position relevée. Figure 5 is a perspective view of the support piece of the screw according to the invention in the raised position.
Dans les exemples représentés sur les figures 1 et 2, la vis selon l'invention 5 comprend une tige comportant trois parties: É une partie inférieure 3a d'une hauteur égale à environ le tiers de celle de la tige 3, d'un diamètre inférieur à celui de la partie médiane 3b et comportant un filetage; É une partie médiane 3b d'une hauteur sensiblement supérieure au tiers de 10 celle de la tige 3; É une partie supérieure 3c d'une hauteur sensiblement inférieure au tiers de celle de la tige 3, présentant des flancs aplatis, un orifice, et ayant un diamètre inférieur à celui de la partie inférieure 3a. In the examples shown in Figures 1 and 2, the screw according to the invention 5 comprises a rod comprising three parts: E a lower part 3a of a height equal to about one third of that of the rod 3, a diameter less than that of the middle portion 3b and having a thread; E a median portion 3b of a height substantially greater than one third of that of the rod 3; An upper part 3c of a height substantially less than one third of that of the rod 3, having flattened sides, an orifice, and having a smaller diameter than that of the lower part 3a.
La tige 3 peut être composée de divers métaux dont l'acier ou le laiton. The rod 3 may be composed of various metals including steel or brass.
La vis 1 s'engage dans une rondelle 2 qui peut être en matière plastique. Cette rondelle qui peut coulisser sur la partie médiane 3b de la tige 3 est destinée à servir de butée entre une.pièce d'appui 4 et les pièces mécaniques à visser. The screw 1 engages in a washer 2 which may be plastic. This washer which can slide on the middle part 3b of the rod 3 is intended to serve as a stop between a piece of support 4 and the mechanical parts to be screwed.
La vis selon l'invention comprend également une pièce d'appui 4 à profil de came montée pivotante à l'extrémité de la tige 3 autour d'un axe perpendiculaire à l'axe longitudinal de ladite vis 1. The screw according to the invention also comprises a support piece 4 with a cam profile pivotally mounted at the end of the rod 3 around an axis perpendicular to the longitudinal axis of said screw 1.
Cette pièce d'appui 4 est prolongée par un levier 6 disposé de manière à prendre deux positions, à savoir une première position dans laquelle le levier 6 s'étend sensiblement parallèlement à l'axe de la vis 1, et la distance de l'axe de pivotement à la zone d'appui de la surface de came rapportée dans l'axe de la vis 1 présente une valeur minimale dI, et une deuxième position dans laquelle ledit levier s'étend sensiblement perpendiculairement à l'axe de la vis et ladite distance présente une valeur maximum dm, 2868488 5 Cette pièce d'appui 4 comporte un évidement du côté opposé audit levier 6 et un orifice qui la traverse de part en part. This support piece 4 is extended by a lever 6 arranged to take two positions, namely a first position in which the lever 6 extends substantially parallel to the axis of the screw 1, and the distance of the pivot axis to the bearing area of the cam surface reported in the axis of the screw 1 has a minimum value dI, and a second position in which said lever extends substantially perpendicular to the axis of the screw and said distance has a maximum value dm, 2868488 5 This support piece 4 has a recess on the opposite side to said lever 6 and an orifice which passes through it from side to side.
La pièce d'appui 4 recouvre la partie supérieure 3c de la tige 3, l'assemblage des deux pièces 3, 4 étant réalisé au moyen d'une goupille 5 qui peut être en métal et qui traverse les orifices de la partie supérieure 3c de la tige 3 et de la pièce d'appui 4. The support piece 4 covers the upper part 3c of the rod 3, the assembly of the two parts 3, 4 being made by means of a pin 5 which can be made of metal and which passes through the orifices of the upper part 3c of the rod 3 and the support piece 4.
Ainsi, de manière avantageuse, grâce à cette goupille 5, il est possible d'imprimer un mouvement de basculement de la pièce d'appui 4 dans un plan vertical de telle sorte que le levier 6 puisse prendre les deux susdites positions. Thus, advantageously, thanks to this pin 5, it is possible to print a tilting movement of the support piece 4 in a vertical plane so that the lever 6 can take the two aforesaid positions.
De plus, la pièce d'appui 4 est fixée à la tige 3 de façon à être désaxée par rapport à celle ci, ce désaxage permettant d'augmenter le couple exercé sur la pièce d'appui 4, à la fois pour assurer le vissage de la vis 1 et pour exercer un effort axial de serrage sur les pièces mécaniques à visser lors de la rotation du profil de came de la première à la seconde position. In addition, the support piece 4 is fixed to the rod 3 so as to be off-axis with respect thereto, this offset making it possible to increase the torque exerted on the support piece 4, both to ensure the screwing of the screw 1 and to exert an axial clamping force on the mechanical parts to be screwed during the rotation of the cam profile from the first to the second position.
La pièce d'appui 4 peut être composée de laiton ou de plastique rigide. The support piece 4 may be made of brass or rigid plastic.
Tel que cela est représenté sur la figure 3, la vis selon l'invention peut s'engager dans une cheville 7, cette cheville 7 pouvant être en nylon. As shown in Figure 3, the screw according to the invention can engage in an ankle 7, the pin 7 may be nylon.
Le fonctionnement de ce dispositif est alors le suivant: L'opérateur effectue une action de vissage en engendrant une rotation de la vis 1 dont la pièce d'appui 4 est placée dans la première position. The operation of this device is as follows: The operator performs a screwing action by generating a rotation of the screw 1, the support part 4 is placed in the first position.
En fin de vissage, l'utilisateur bascule la pièce d'appui dans sa seconde position. Au cours de ce basculement la pièce d'appui 4 exerce, en raison de son profil de came, un effort de traction sur la vis et parallèlement un effort de serrage des deux pièces l'une contre l'autre, la rondelle 2 venant s'interposer entre la pièce d'appui 4 et la pièce mécanique à visser. At the end of screwing, the user tilts the support piece in its second position. During this tilting, the support piece 4 exerts, due to its cam profile, a tensile force on the screw and in parallel a clamping force of the two parts against each other, the washer 2 coming interpose between the support piece 4 and the mechanical part to be screwed.
