Abstract

This device for locking together a male endpiece 1 and a female endpiece 2 is of the type comprising a finger 3 carried by the male endpiece, received in an orifice 8 made in the female endpiece. According to the invention, a ball 9 forming a pushbutton is retained in this orifice and when the two endpieces are assembled, this ball is pushed into a position in which it projects with respect to the surface 2<a> of the female component. It is then sufficient for the user to press on the ball in order to press the locking finger into its housing and then to be able to disengage the endpieces axially. The device can be applied in particular in the field of hand tools.

Description

La présente invention concerne un dispositif de verrouillage entre deux pièces ou embouts complémentaires,respectivement male et femelle,utilisables notamment dans le domaine de l'outillage. The present invention relates to a locking device between two complementary parts or end pieces, male and female respectively, usable in particular in the field of tooling.
Pour réaliser le verrouillage positif d'embouts complémentaires male et femelle,il est connu de prévoir sur l'embout male un doigt de verrouillage reçu dans un logement et sollicité vers l'extérieur par un ressort de compression prenant appui contre le fond du logement.Ce doigt eoopère,en position d'assemblage des deux embouts, avec un orifice ménagé dans la paroi latérale adjacente de l'embout femelle.Pour engager l'embout mâle dans l'embout femelle,l'utilisateur doit repousser le doigt de verrouillage dans son logement, a l'encontre du ressort, et maintenir cette pression le temps que la paroi de l'embout femelle vienne assurer le maintien du doigt de verrouillage à l'intérieur de son logement.En position asssemblée des deux embouts,le doigt de verrouillage s'enclenche dans l'orifice de l'embout femelle pour assurer le blocage posi tif de l'ensemble. To achieve positive locking of complementary male and female end pieces, it is known to provide on the male end piece a locking finger received in a housing and urged outwardly by a compression spring bearing against the bottom of the housing. This finger engages, in the assembly position of the two end pieces, with an orifice made in the adjacent side wall of the female end. To engage the male end in the female end, the user must push the locking finger back into the socket. its housing, against the spring, and maintain this pressure while the wall of the female end comes to maintain the locking finger inside its housing. locking engages in the orifice of the female end to ensure the posi tive locking of the assembly.
Pour déverrouiller les pièces,il faut enfoncer l'extrémité d'un outil dans l'orifice de l'embout femelle pour repousser le doigt de verrouillage dans son logement.On peut alors libérer et dégager les embouts l'un de l'autre. To unlock the parts, you have to push the end of a tool into the hole in the female connector to push the locking finger back into its housing. You can then release and disengage the bits from each other.
L'inconvénient essentiel d'un tel agencement provient de l'uti~lisation d'un troisième élément ou outil extérieur pour repousser le doigt de verrouillage à l'intérieur de son logement préalablement au dégagement des deux embouts. The essential drawback of such an arrangement comes from the uti ~ lization of a third element or external tool to push the locking finger inside its housing prior to the release of the two end pieces.
Un autre inconvénient résulte du fait qu'il est nécessaire d'exercer une pression sur ledit doigt préalablement à l'assemblage. Another drawback results from the fact that it is necessary to exert pressure on said finger prior to assembly.
L'invention vise à pallier ces deux inconvénients, essentiellement le premier d'entre eux, et à fournir un dispositif simple évitant l'emploi d'un outil pour déverrouiller les deux embouts. The invention aims to overcome these two drawbacks, essentially the first of them, and to provide a simple device avoiding the use of a tool to unlock the two end pieces.
A cet effetvl'invention a pour objet un dispositif de verrouillage positif entre deux embouts complémentaires, respectivement male et femelle,comprenant un doigt porté par
l'embout mâlebsollicité par un ressort vers une posi
tion de verrouillage dans laquelle ce doigt fait saillie
par rapport à une paroi latérale de l'embout male et un ori
fice ménagé dans une paroi adjacente,de l'embout femelle, dans lequel le doigt s'engage en position de verrouillage, caractérisé en ce qu'un organe formant poussoir est monté libre dans ledit orifice1 tout en y étant retenu, la dimension de cet organe étant telle qu'en position de verrouillage il fait saillie par rapport à la paroi externe de l'embout femelle.
To this end, the invention relates to a positive locking device between two complementary end pieces, respectively male and female, comprising a finger carried by
the male end requested by a spring towards a posi
locking tion in which this finger protrudes
relative to a side wall of the male end and an ori
fice formed in an adjacent wall, of the female end, in which the finger engages in the locking position, characterized in that a member forming a pusher is mounted free in said orifice1 while being retained there, the dimension of this member being such that in the locked position it protrudes relative to the outer wall of the female end.
Suivant un mode de réalisation préférél'orga- ne formant poussoir est une bille reçue librement dans ledit orifice,entre deux parties d'extrémité,de diamètre réduit, de ce dernier. According to a preferred embodiment, the pusher-forming member is a ball received freely in said orifice, between two end portions, of reduced diameter, of the latter.
Suivant une autre caractéristique,l'embout femelle: comporte un chanfrein réalisé sur au moins une partie du pourtour intérieur de son extrémité dirigée vers l'embout mâle. According to another characteristic, the female end: comprises a chamfer made on at least part of the inner periphery of its end directed towards the male end.
L'invention a également pour objet l'ensemble constitué par les deux pièces à embouts respectifs male et femelle munis du dispositif de verrouillage défini précédemment
L'invention va etre décrite plus en détail ci-dessous en se référant aux dessins annexés,donnés uniquement à titre d'exemple et sur lesquels
- La Fig.l est une vue en coupe des embouts mâle et femelle prêts à être assemblés
- La Fig.2 est une vue en coupe des memes embouts mâle et femelle assemblés et verrouillés.
The subject of the invention is also the assembly formed by the two pieces with respective male and female ends provided with the locking device defined above.
The invention will be described in more detail below with reference to the accompanying drawings, given solely by way of example and in which
- Fig.l is a sectional view of the male and female end pieces ready to be assembled
- Fig.2 is a sectional view of the same male and female end pieces assembled and locked.
Les deux embouts respectivement mâle 1 et femelle 2 reprosentés sur le dessin peuvent etreSpar exemple, l'extrémité d'un manche d'outil et l'extrémité d'un outil interchangeable.Ces deux embouts ont de préférence une section transversale carrée ou rectangulaire,mais unè telle forme n'est pas indispensable. The two ends respectively male 1 and female 2 shown in the drawing can be, for example, the end of a tool handle and the end of an interchangeable tool. These two ends preferably have a square or rectangular cross section, but such a form is not essential.
L'embout male 1 comporte un doigt de verrouillage 3 reçu dans un logement 4 au fond duquel s'appuie un ressort 5 tendant à repousser le doigt 3 vers l > extérîeur, en saillie par rapport à la paroi latérale adjacente la de l'embout 1. Le doigt 3 comporte un épaulement radial '~.qui, venant en butée contre un rebord 4a du logement 4 assure la retenue du doigt dans son logement. The male end piece 1 comprises a locking finger 3 received in a housing 4 at the bottom of which rests a spring 5 tending to push the finger 3 towards the outside, projecting from the adjacent side wall of the end piece. 1. The finger 3 has a radial shoulder '~ .qui, abutting against a flange 4a of the housing 4 ensures the retention of the finger in its housing.
A son extrémité 6 dirigée vers l'embout mâle 1,l'embout femelle 2 comporte un chanfrein 7 dirigé vers l'intérieur et qui s'étend sur une partie seulement de son pourtour. At its end 6 directed towards the male end piece 1, the female end piece 2 comprises a chamfer 7 directed inwards and which extends over only a part of its periphery.
L'embout femelle 2veomporte,dans sa paroi terminée par le chanfrein un orifice 8,s'étendant radialement par rapport à l'axe longitudinal des deux embouts. -. The female end piece 2veomporte, in its wall terminated by the chamfer, an orifice 8 extending radially with respect to the longitudinal axis of the two end pieces. -.
Cet orifice 8 contient une bille 9 qui peut se déplacer librement dans celui-ci et qui est retenue aux bords extre- mes dudit trou 8 par des rétrécissements inférieur 10 et supérieur 11,spi l'on se réfère à la Fig.l.Le diamètre de la bille 9 est tel qu'en position verrouillee des deux embouts elle fait saillie par rapport à la surface externe 2 a de la paroi de l'embout femelle 2,d'une hauteur h qui est de pré férence légèrement supérieure à la distance d dont le doigt 3 fait saillie dans l'orifice 8 (Fig.2). This orifice 8 contains a ball 9 which can move freely therein and which is retained at the end edges of said hole 8 by lower 10 and upper 11 constrictions, with reference to FIG. diameter of the ball 9 is such that in the locked position of the two end pieces it protrudes relative to the outer surface 2a of the wall of the female end piece 2, by a height h which is preferably slightly greater than the distance d from which the finger 3 protrudes into the orifice 8 (Fig. 2).
Le fonctionnement du dispositif décrit cidessus est le suivant: lorsqu'on rapproche les embouts complémentaires mâle 1 et femelle 2 pour les assembler,le chanfrein 7 repousse le doigt 3 à l'intérieur de son logement 4. The operation of the device described above is as follows: when the complementary male 1 and female 2 ends are brought together to assemble them, the chamfer 7 pushes the finger 3 back inside its housing 4.
En fin d'assemblage,le doigt 3 s'engage dans l'orifice 8 en position de verrouillage et repousse la bille 9 contre le rétrécissement supérieur 11 (Fig.2).At the end of assembly, the finger 3 engages in the orifice 8 in the locking position and pushes the ball 9 against the upper constriction 11 (Fig.2).
Pour déverrouiller l'ensemble,il suffit d'appuyer sur la bille 9 en saillie,afin de repousser à nouveau le doigt 3 dans son logement 4.Le dégagement des embouts s opère alors par simple traction longitudinale. To unlock the assembly, it suffices to press on the projecting ball 9, in order to push the finger 3 back into its housing 4. The end pieces are then released by simple longitudinal traction.
Ainsi,grâce à la bille 9 formant pous soirìl n'est pas nécessaire d'utiliser un organe supplémen taire pour repousser le doigt 3 dans son logement 4 lors de l'opération de déverrouillage des embouts. Thus, thanks to the ball 9 forming a push-button, it is not necessary to use an additional member to push the finger 3 back into its housing 4 during the operation of unlocking the end pieces.
De plus,la présence du chanfrein 7 facilite l'engagement des deux embouts puisque l'utilisateur n'a pas à exercer de pression sur le doigt 3 pour réaliser l'effacement de ce dernier.In addition, the presence of the chamfer 7 facilitates the engagement of the two end pieces since the user does not have to exert pressure on the finger 3 to effect the erasure of the latter.
Les moyens mis en jeu pour obtenir ces résultats sont par ailleurs très simples et peu coûteux, ce qui est essentiel dans les applications envisagées,notamment :assemblage d'une. douille sur une clé à cliquet,d'un embout dynamométrique ou d'autres accessoires sur un manche ou support analogue. The means used to obtain these results are moreover very simple and inexpensive, which is essential in the applications envisaged, in particular: assembly of a. socket on a ratchet, a torque bit or other accessories on a handle or the like.
