Description

  

  Dispositif     d'actionnement    à     la    main d'une pièce filetée    La présente invention a pour objet un dis  positif     d'actionnement    à la main d'une pièce  filetée présentant des pans pour son     actionne-          ment,    caractérisé en ce qu'il comprend un or  gane de     manoeuvre    capable de glisser     axiale-          ment    sur les pans et un organe de retenue  sollicité     élastiquement    à s'engager dans des  moyens de prise que présentent les pans,

   de  manière à retenir engagé l'organe de     manoeu-          vre    en position active sur ladite pièce filetée  contre un détachement fortuit et à permettre le  retrait de cet organe par une traction dans le  sens de l'axe du filet.  



  La figure unique du dessin représente en  coupe, à titre d'exemple, une forme d'exécution  du dispositif selon l'invention.  



  Le dispositif représenté est destiné à ac  tionner un écrou six-pans 1 dont chaque pan  présente une creusure 2. Il comprend un or  gane de     manoeuvre    creux 3 capable de glisser       axialement    sur les pans de l'écrou 1, et un  manche 4, vissé dans l'organe 3 et destiné à  lit commande de la rotation de cet organe. Le  manche 4 présente un trou borgne 5 dans le  quel sont disposés un ressort 6 et un organe de  retenue constitué par une bille 7. Le ressort 6  est monté à compression entre le fond du trou  et la bille 7.

   Un léger sertissage de l'extrémité  du trou empêche la bille d'être chassée du  trou par le ressort 6, la bille faisant cependant    saillie à     l'extrémité    du manche 5 et à l'intérieur  de l'organe de     manoeuvre    3. Il est évident que  la forme intérieure de l'organe 3 est complé  mentaire de celle de l'écrou 1 à actionner.  



  Quand on veut actionner l'écrou,     c'est-à-          dire    le visser ou le dévisser, on vient le     coiffer     avec l'organe 3 et on fait glisser ce dernier       axialement    sur les pans de l'écrou. Pendant  ce mouvement, la bille 7 est repoussée contre  l'action du ressort 6, jusqu'à ce qu'elle arrive  au niveau d'une creusure 2. A ce moment, le  ressort pousse la bille dans la creusure, de  manière à retenir engagé l'organe de     manoeu-          vre    en position active sur ledit écrou, contre  tout détachement fortuit.

   L'organe de     manoeu-          vre    3 pourra ainsi transmettre un couple à  l'écrou 1 sans risquer d'être détaché de sa posi  tion active. Cependant, par une traction sur  l'organe 3 dans le sens de l'axe du filet il est  possible, à volonté, de retirer l'organe 3 de  l'écrou 1.



  Device for manual actuation of a threaded part The present invention relates to a device for manual actuation of a threaded part having flaps for its actuation, characterized in that it comprises a operating handle capable of sliding axially on the panels and a retaining member elastically urged to engage in the gripping means presented by the panels,

   so as to retain engaged the operating member in the active position on said threaded part against accidental detachment and to allow the withdrawal of this member by traction in the direction of the axis of the thread.



  The single figure of the drawing shows in section, by way of example, an embodiment of the device according to the invention.



  The device shown is intended to actuate a hexagon nut 1, each side of which has a recess 2. It comprises a hollow operating member 3 capable of sliding axially on the sides of the nut 1, and a handle 4, screwed on. in member 3 and intended for controlling the rotation of this member. The handle 4 has a blind hole 5 in which are arranged a spring 6 and a retaining member constituted by a ball 7. The spring 6 is mounted in compression between the bottom of the hole and the ball 7.

   A slight crimping of the end of the hole prevents the ball from being forced out of the hole by the spring 6, the ball however projecting at the end of the handle 5 and inside the actuator 3. It is obvious that the internal shape of the member 3 is complementary to that of the nut 1 to be actuated.



  When we want to actuate the nut, that is to say screw it or unscrew it, we cap it with the member 3 and we slide the latter axially on the sides of the nut. During this movement, the ball 7 is pushed against the action of the spring 6, until it reaches the level of a recess 2. At this moment, the spring pushes the ball into the recess, so as to retain engaged the actuator in the active position on said nut, against any accidental detachment.

   The actuator 3 will thus be able to transmit a torque to the nut 1 without running the risk of being detached from its active position. However, by pulling the member 3 in the direction of the axis of the thread it is possible, at will, to remove the member 3 from the nut 1.

REVENDICATION Dispositif d'actionnement à la main d'une pièce filetée présentant des pans pour son ac- tionnement, caractérisé en ce qu'il comprend un organe de manoeuvre capable de glisser axialement sur les pans et un organe de rete nue sollicité élastiquement à s'engager dans des moyens de prise que présentent les pans, CLAIM Device for manual actuation of a threaded part having flats for its actuation, characterized in that it comprises an operating member capable of sliding axially on the flaps and a retaining member elastically biased to s. '' engage in the gripping means presented by the panels, de manière à retenir engagé l'organe de ma- noeuvre en position active sur ladite pièce filetée contre un détachement fortuit et à per mettre le retrait de cet organe par une traction dans le sens de l'axe du filet. SOUS-REVENDICATION Dispositif selon la revendication, caracté risé en ce qu'il comprend un manche solidaire de l'organe de manoeuvre pour la commande de ce dernier, ledit organe de retenue compre nant une bille logée dans ce manche, so as to retain engaged the actuating member in the active position on said threaded part against accidental detachment and to allow the withdrawal of this member by traction in the direction of the axis of the thread. SUB-CLAIM Device according to claim, characterized in that it comprises a handle integral with the operating member for controlling the latter, said retaining member comprising a ball housed in this handle, poussée par un ressort vers l'intérieur de l'organe de manoeuvre et maintenue par sertissage à l'ex trémité du manche de manière à faire saillie à l'intérieur dudit organe de manoeuvre, afin de s'engager dans des creusures pratiquées dans lesdits pans quand l'organe de manoeuvre est en position active. pushed by a spring towards the inside of the operating member and held by crimping at the end of the handle so as to protrude inside said operating member, in order to engage in recesses made in said panes when the actuator is in the active position.
