Description
DISPOSITIF A MORS ELASTIQUE MUNI D'UNE MASSELOTTE MOBILE ET
CONSTITUANT UNE BUTEE AXIALE AMOVIBLE.ELASTIC JAW DEVICE PROVIDED WITH A MOBILE GUN AND
CONSTITUTING A REMOVABLE AXIAL STOP.
On a déjà proposé de constituer une butée axiale au moyen de deux ressorts à lames inclinées formant mors qui autorise l'insertion d'un axe dans le sens qui écarte les lames et interdit par coincement son déplacement en sens inverse.It has already been proposed to constitute an axial stop by means of two inclined leaf springs forming jaws which allows the insertion of an axis in the direction which separates the blades and prevents by jamming its movement in the opposite direction.
L'invention propose de faire prendre appui aux portions terminales des lames sur une masselotte mobile percée d'un orifice de passage de l'axe.The invention proposes making the terminal portions of the blades bear on a movable counterweight pierced with an orifice for the passage of the axis.
Cette masselotte réduit l'élasticité du ressort, donc renforce le blocage axial et sert au déblocage si on la déplace à l'aide d'un outil ou d'un aimant dans le sens qui écarte les lames.This counterweight reduces the elasticity of the spring, therefore reinforces the axial locking and is used for unlocking if it is moved using a tool or a magnet in the direction which spreads the blades.
L'invention sera mieux comprise à l'aide de la description ci-après.The invention will be better understood with the aid of the description below.
Au dessin annexé :
La figure 1 illustre l'insertion d'un axe dans une
butée axiale conforme à un mode d'exécution de l'invention
La figure 2 illustre le blocage de l'axe à l'extrac
tion
La figure 3 illustre le déverrouillage de l'axe par
déplacement de la masselotte
La figure 4 est une vue en plan de la butée selon la
figure 1 ; et
La figure 5 montre une variante d'exécution de la
masselotte.In the attached drawing:
Figure 1 illustrates the insertion of an axis in a
axial stop according to an embodiment of the invention
Figure 2 illustrates the locking of the axis at the extrac
tion
FIG. 3 illustrates the unlocking of the axis by
moving the flyweight
Figure 4 is a plan view of the stop along the
figure 1 ; and
Figure 5 shows an alternative embodiment of the
flyweight.
On voit aux figures 1 et 4 que la butée illustrée comprend une plaque de base 1 percée d'un orifice médian 2 pour le passage de l'axe A. Les petits côtés de la plaque 1 sont prolonges dans leur partie médiane par des lames de ressort 3-4 symétriquement inclinées par rapport au plan de la plaque et dont les bords libres en regard ménagent, en position de repos des lames, un passage pour l'axe A.It can be seen in FIGS. 1 and 4 that the illustrated stop comprises a base plate 1 pierced with a median orifice 2 for the passage of the axis A. The short sides of the plate 1 are extended in their median part by blades of spring 3-4 symmetrically inclined with respect to the plane of the plate and the free edges opposite provide, in the blade rest position, a passage for the axis A.
Avantageusement, des découpes 30-40 (figure 4) facilitent le centrage de l'axe et réduisent l'intervalle entre les bords libres des lames.Advantageously, cutouts 30-40 (Figure 4) facilitate the centering of the axis and reduce the interval between the free edges of the blades.
Une masselotte 5, représentée aux figures 1 et 4, avec une forme parallélépipédique, et munie d'un orifice 50 de diamètre supérieur à celui de l'orifice 30, est mise en place sur la plaque 1 de façon que les orifices 30 et 50 soient coaxiaux.A counterweight 5, shown in Figures 1 and 4, with a parallelepiped shape, and provided with an orifice 50 of diameter greater than that of the orifice 30, is placed on the plate 1 so that the orifices 30 and 50 are coaxial.
Lorsqu'on insère l'axe dans la butée axiale ainsi constituée, dans le sens de la flèche de la figure 1, les lames s'écartent et autorisent ainsi le passage de l'axe. Au cours de cette opération, les lames ne sont pas en contact avec la masselotte. Mais, dès que l'on cesse de déplacer l'axe, elles viennent en appui sur les bords de la masselotte, comme le montre la figure 2. I1 est évident que si l'on tente de déplacer l'axe dans le sens de la flèche de la figure 2 pour l'extraire, non seulement les bords des lames vont venir coincer l'axe, mais seules leurs portions terminales situées au-delà des lignes de contact avec la masselotte, vont pouvoir s'infléchir : l'élasticité du ressort est ainsi notablement réduite et l'effort d'extraction accru.Dans la variante de la figure 5, où la masselotte comporte de chaque côté un pan coupé 51-52, la surface d'appui des lames sera beaucoup plus grande qu'à la figure 2 et les forces de blocage seront donc considérablement accrues.When the axis is inserted into the axial stop thus formed, in the direction of the arrow in FIG. 1, the blades move apart and thus allow the axis to pass. During this operation, the blades are not in contact with the counterweight. But, as soon as we stop moving the axis, they come to bear on the edges of the counterweight, as shown in FIG. 2. It is obvious that if we try to move the axis in the direction of the arrow of FIG. 2 to extract it, not only will the edges of the blades come to jam the axis, but only their end portions located beyond the lines of contact with the counterweight, will be able to bend: the elasticity spring is thus significantly reduced and the extraction force increased. In the variant of FIG. 5, where the counterweight has on each side a cutaway 51-52, the bearing surface of the blades will be much greater than in FIG. 2 and the blocking forces will therefore be considerably increased.
Pour déverrouiller l'axe, il suffit de déplacer la masselotte axialement dans un sens propre à écarter les lames (figure 3) : l'axe peut alors être déplacé librement dans un sens ou dans l'autre.To unlock the axle, simply move the counterweight axially in a direction suitable for spreading the blades (Figure 3): the axle can then be moved freely in one direction or the other.
Ce déplacement de la masselotte peut s'effectuer au moyen d'un aimant de forte puissance ou d'un électro-aimant, ou à l'aide d'un outil approprié.This movement of the counterweight can be carried out by means of a strong power magnet or an electromagnet, or by means of an appropriate tool.
Les applications d'un tel dispositif sont nombreuses et l'on citera seulement, à titre d'exemple - la fixation axiale d'une poignée de porte ; - la fixation d'un badge" sur un vêtement pour le protéger
contre le vol dans un magasin ; l'axe sera alors celui
d'un dispositif du genre punaise et aura un diamètre de
1 mm par exemple : il pourra donc traverser le tissu, qui
sera interposé entre la plaque 1 et une tête formant "badge". The applications of such a device are numerous and we will only cite, by way of example - the axial fixing of a door handle; - the fixing of a badge "on a garment to protect it
against theft in a store; the axis will then be that
of a device of the pushpin type and will have a diameter of
1 mm for example: it can therefore cross the fabric, which
will be interposed between the plate 1 and a head forming a "badge".
I1 va de soi que la forme et les dimensions du dispositif pourront varier sans s'écarter de l'esprit de l'invention. It goes without saying that the shape and dimensions of the device may vary without departing from the spirit of the invention.
