Abstract

The unit consists of an exterior sleeve (1) threaded (2) and pierced axially with a longitudinal hole (10) along its whole length. This allows a fixing screw (11) or (13) to be introduced into this hole whereby the whole unit is fixed to one element (5). A second element (9) pierced with a hole is fitted over the exterior sleeve, and positionally-adjusted by a nut (8) threaded onto the external thread of the exterior sleeve. USE/ADVANTAGE - As a double-function screw for adjusting and fixing together two elements, instead of using two separate items to carry out this function.

Description

VIS DOUBLE FONCTION
La présente invention concerne le réglage et la fixation selon un même axe de deux éléments superposés.DUAL FUNCTION SCREW
The present invention relates to the adjustment and fixing along the same axis of two superimposed elements.

Le réglage et la fixation de deux éléments superposés sont habituellement réalisés par des montages dissociés en séparant les deux fonctions. The adjustment and the fixing of two superimposed elements are usually carried out by dissociated assemblies by separating the two functions.

La technologie existante contraint d adopter une vis de réglage , puis dans un environnement proche une vis de fixation . Ceci entraine une réaction d'une vis sur l'autre amenant des difficultés de réglage Z ainsi qu'une mauvaise fixation.  Existing technology requires adopting an adjusting screw, then in a close environment a fixing screw. This causes a reaction from one screw to the other, causing difficulties in adjusting Z as well as poor fixing.

Le dispositif selon l'invention permet de palier a ces inconvénients. Il comporte selon une premiere caractéristique une enveloppe extérieure creuse permettant concentriquement l'introduction de son système de fixation. Cette enveloppe possede sur son diamètre extérieur un filetage permettant le réglage. Elle est vissée sur l'élément de base. Une de ses extrémités est décolletée d un diamètre inférieur au diamètre de fond de filet du filetage du diamètre extérieur puis rayonné d'une valeur sensiblement égale d la moitié de la longueur totale de l'enveloppe. Cette extrémité en appui sur l'élément a régler ) constitue la touche de contact pour le réglage. Cet élément a régler possède 9 cet effet un chambrage conique.Selon une variante ce chambrage conique peut être rapporté par une rondelle portant ce chambrage conique et intercalée entre l'élément ^e régler et l'extrémité rayonnée de l'enveloppe. The device according to the invention overcomes these drawbacks. According to a first characteristic, it has a hollow outer envelope which concentrically allows the introduction of its fixing system. This envelope has on its outside diameter a thread allowing adjustment. It is screwed onto the base element. One of its ends is turned with a diameter less than the thread diameter of the thread of the outside diameter and then radiated by a value substantially equal to half the total length of the envelope. This end resting on the element to be adjusted) constitutes the contact key for the adjustment. This element to be adjusted has 9 this effect a conical recess. According to a variant this conical recess can be added by a washer carrying this conical recess and interposed between the element ^ e adjust and the radiated end of the envelope.

L'autre extrémité est usinée en carré puis décolletée d un diamètre inférieur au diamètre de fond de filet du filetage du diamètre extérieur. Cette extrémité permet la préhension pour la rotation de l'enveloppe afin de réglage
Un écrou monté sur le filetage extérieur de l'enveloppe assure après son serrage contre l'élément de base du montage l'immobilisetion de l'enveloppe sur celui-ci. Cette enveloppe est perlée longitudinalement en son centre sur toute sa longueur.The other end is machined in a square and then turned with a diameter smaller than the thread diameter of the thread of the outside diameter. This end allows gripping for rotation of the envelope in order to adjust
A nut mounted on the external thread of the casing ensures, after being tightened against the base element of the assembly, that the casing remains immobilized thereon. This envelope is beaded longitudinally in its center over its entire length.

Ce perçage permet deux montages possibles:
a/ Une vis de fixation munie d'une rondelle élastique , introduite dans ce perçage, puis vissée dans l'élément réglé, constitue un assemblage rigide des deux éléments réglés et assemblés.This drilling allows two possible assemblies:
a / A fixing screw fitted with an elastic washer, introduced into this hole, then screwed into the adjusted element, constitutes a rigid assembly of the two adjusted and assembled elements.

b/ Une vis de fixation plus longue permettant d'intercaler une rondelle plate et un ressort a boudins entre l'extrémité carrée de l'enveloppe et la tête de cette vis , introduite dans ce perçage , puis vissée dans l'élément réglé, constitue un assemblage flottant des deux éléments réglés et assemblés. b / A longer fixing screw making it possible to insert a flat washer and a coil spring between the square end of the casing and the head of this screw, introduced into this bore, then screwed into the adjusted element, constitutes a floating assembly of the two adjusted and assembled elements.

Les dessins annexés illustrent l'invention:
La figure 1 représente en coupe un montage rigide de l'invention.The accompanying drawings illustrate the invention:
Figure 1 shows in section a rigid assembly of the invention.

Le figure 2 représente en coupe un montage flottant de l'invention. Figure 2 shows in section a floating assembly of the invention.

En référence a' ces dessins, le dispositif comporte une enveloppe extérieure (1) creuse possédant un diamètre extérieur fileté (2) destiné au réglage. L'une de ses extrémités (3) est décolletée , puis rayonnée (4) afin de constituer la touche d'appui sur l'élément si régler (5). Cet élément a régler (5) possede a cet effet un chambrage conique (6). L'autre extrémité (7) est usinée en carré pour permettre a' l'aide d'un outil la rotation de l'enveloppe (1). Un écrou (8) est monté sur le filetage extérieur (2) qui après son serrage contre l'élément de base (9), immobilisera l'enveloppe (1) .Cette enveloppe ( 1 ) est percée longitudinalement d'un trou cylindrique (10). Ce perçage (10) permet au choix le montage d'une vis de fixation (11) munie d'une rondelle élastique (12) vissée dans l'élément réglé (5) afin de constituer un assemblage rigide des deux éléments (5) et (9) réglés et assembles , ou le montage d'une vis (13) plus longue permettant d'intercaler une rondelle plate (14) et un ressort à boudins (15) entre l'extrémité carrée (7) de l'enveloppe (1) et la tête de cette vis (13) vissée dans l'élément réglé (5) afin de constituer un assemblage flottant des deux éléments (5) et (9) régles et assemblés. Le diamètre de ce perçage (10) sera supérieur au diamètre des vis ( ou (13) d'une valeur permettant une inclinaison de l'élément a régler (5) par rapport à l'élément de base (9).Referring to these drawings, the device comprises a hollow outer casing (1) having a threaded outer diameter (2) intended for adjustment. One of its ends (3) is turned, then radiated (4) in order to constitute the touch button on the element if set (5). This adjusting element (5) has for this purpose a conical recess (6). The other end (7) is machined in a square to allow the rotation of the envelope (1) using a tool. A nut (8) is mounted on the external thread (2) which, after being tightened against the base element (9), will immobilize the envelope (1). This envelope (1) is drilled longitudinally with a cylindrical hole ( 10). This drilling (10) allows the choice of mounting a fixing screw (11) provided with an elastic washer (12) screwed into the adjusted element (5) in order to constitute a rigid assembly of the two elements (5) and (9) adjusted and assembled, or the mounting of a longer screw (13) allowing a flat washer (14) and a coil spring (15) to be inserted between the square end (7) of the casing ( 1) and the head of this screw (13) screwed into the adjusted element (5) in order to constitute a floating assembly of the two elements (5) and (9) adjusted and assembled. The diameter of this bore (10) will be greater than the diameter of the screws (or (13) by a value allowing an inclination of the element to be adjusted (5) relative to the base element (9).

Selon une variante non illustrée, le cambrage conique (6) peut être rapporté par une rondelle portant ce chambrage et intercalée entre l'élément a regler (5) et l'extrémité rayonnée (4) de l'enveloppe (1).  According to a variant not illustrated, the conical camber (6) can be added by a washer carrying this recess and interposed between the element to be adjusted (5) and the radiated end (4) of the envelope (1).

A titre d'exemple non limitatif , l'enveloppe aura un diamètre extérieur de 30 mm et une longueur de 70 mm. By way of nonlimiting example, the envelope will have an outside diameter of 30 mm and a length of 70 mm.

Le dispositif selon l'invention est destiné au réglage et à la fixation de deux éléments superposés.  The device according to the invention is intended for adjusting and fixing two superimposed elements.
