Abstract

The mechanism is used for a surgical microscope and controlled by an electromagnet to block rotation of the microscope about a vertical axis when it is in use. The movable arm (2) which is mounted on the vertical axis is gripped by a stack of curved washers (1). The curved spring washers normally provide enough friction to prevent rotation. An electromagnet (7) to one side of the axle is arranged to release the pressure which normally maintains the coupling in the locked state. The armature (7a) of the electromagnet is arranged to move vertically and is attached to a horizontal lever (8) pivoted (9) on top of a bracket (6) which is attached to the axle. When the electromagnet is energised, the lever acts on a peg (4) and stop (3) above the stack of spring washers in order to release them, and allow movement of the coupling.

Description

Le présent certificat d'addition se rapporte à un dispositif de blocage d'axes verticaux dans les installations de support de microscope chirurgical, comportant plusieurs bras horizontaux. This addition certificate relates to a device for blocking vertical axes in surgical microscope support installations, comprising several horizontal arms.

Le brevet principal décrit une disposition de blocage d'éléments tubulaires télescopiques, destinée plus particulièrement à une suspension de microscope chirurgical, ayant recours à un courant électrique pour engendrer un champ d'annulation des effets de plusieurs dispositifs, à aimant permanent, de retenue axiale verticale, l'absence de courant provoquant immédiatement cette retenue axiale verticale. The main patent describes an arrangement for blocking telescopic tubular elements, intended more particularly for a suspension of a surgical microscope, using an electric current to generate a field for canceling the effects of several devices, with permanent magnet, of axial retention. vertical, the absence of current immediately causing this vertical axial restraint.

Un premier certificat d'addition rattaché au brevet principal donne des éléments techniques complémentaires dans le cas particulier ou la suspension du microscope est composée d'éléments horizontaux articulés autour d'axes verticaux. Le procédé du brevet principal est appliqué dans ce premier certificat d'addition en relation avec d'autres dispositifs de retenue, mais en déplacement rotatif. A first certificate of addition attached to the main patent gives additional technical elements in the particular case where the suspension of the microscope is composed of horizontal elements articulated around vertical axes. The process of the main patent is applied in this first certificate of addition in relation to other retaining devices, but in rotary displacement.

Le présent certificat d'addition décrit encore d'autres moyens plus simples et plus opérationnels pour le blocage des axes verticaux des éléments horizontaux déployables d'un support de microscope chirurgical, ce support pouvant être, soit une suspension plafonnière, soit un support du genre trépied reposant sur le sol. This addition certificate describes other simpler and more operational means for blocking the vertical axes of the deployable horizontal elements of a surgical microscope support, this support being either a ceiling suspension or a support of the kind tripod resting on the ground.

Conformément à la présente invention, le blocage des différents axes verticaux est simultané selon une seule manoeuvre, ledit blocage étant, comme dans le brevet principal, effectif en l'absence de tension électrique et annulé en présence d'une tension électrique. In accordance with the present invention, the blocking of the different vertical axes is simultaneous in a single operation, said blocking being, as in the main patent, effective in the absence of electrical voltage and canceled in the presence of electrical voltage.

Suivant une forme de réalisation avantageuse de l'invention, le dispositif de blocage comprend une série de rondelles-ressorts métalliques ayant pour objet de bloquer par friction un ou plusieurs disques solidaires de l'axe à bloquer, un électro-aimant à levier intermédiaire étant prévu, par ailleurs, pour agir sur lesdites rondelles afin d'annuler la friction des rondelles sur les disques, le blocage étant donc effectif en l'absence de tension électrique appliquée à l'électro-aimant et annulé lors de l'application d'une tension électrique audit électro-aimant.  According to an advantageous embodiment of the invention, the locking device comprises a series of metal spring washers intended to frictionally block one or more discs integral with the axis to be blocked, an electromagnet with an intermediate lever being provided, moreover, to act on said washers in order to cancel the friction of the washers on the discs, the blocking being therefore effective in the absence of electric voltage applied to the electromagnet and canceled during the application of an electrical voltage to said electromagnet.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description qui va suivre, faite en regard du dessin annexé sur lequel
- la figure 1 est une vue en élévation d'un support de microscope chirurgical à éléments horizontaux articulés, ledit support étant une suspension plafonnière ;
- la figure 2 est une vue en élévation d'un autre support à bras horizontaux articulés verticalement pour microscope chirurgical, ce suppo#rt étant du type trépied reposant sur le sol ;
- la figure 3 représente un dispositif de blocage selon l'invention agissant sur un axe vertical d'articulation de bras horizontaux d'une installation de support de microscope chirurgical.Other characteristics and advantages of the present invention will emerge from the description which follows, given with reference to the appended drawing in which
- Figure 1 is an elevational view of a surgical microscope support with articulated horizontal elements, said support being a ceiling suspension;
- Figure 2 is an elevational view of another support with horizontal arms articulated vertically for surgical microscope, this suppo # rt being of the tripod type resting on the ground;
- Figure 3 shows a locking device according to the invention acting on a vertical axis of articulation of horizontal arms of a surgical microscope support installation.

Dans la forme de réalisation représentée, un axe
A vertical d'articulation entre deux bras horizontaux, comme cela se présente sur les figures 1 et 2, dans les cas particuliers d'une suspension plafonnière et d'un support reposant sur le sol, est susceptible d'être-bloqué par des rondellesressorts métalliques 1 agissant sur au moins un disque 2 calé sur ledit axe A. D'une manière plus précise, lesdites rondelles agissent sur une butée 3 solidaire d'une tige 4 laquelle traverse les rondelles et comporte un élément de serrage 5 destiné à venir serrer le disque 2 contre une console fixe 6 traversée elle-même par la tige 4. La console 6 porte, par ailleurs, un électro-aimant 7 dont la tige 7A agit sur un levier 8 articulé en 9 sur la console 6. Le levier articulé 8 est prévu pour agir, à son tour, sur la tige 4.In the embodiment shown, an axis
A vertical articulation between two horizontal arms, as shown in Figures 1 and 2, in the particular cases of a ceiling suspension and a support resting on the ground, is likely to be-blocked by spring washers metallic 1 acting on at least one disc 2 wedged on said axis A. More precisely, said washers act on a stop 3 secured to a rod 4 which passes through the washers and comprises a clamping element 5 intended to come and clamp the disc 2 against a fixed console 6 itself traversed by the rod 4. The console 6 carries, moreover, an electromagnet 7 whose rod 7A acts on a lever 8 articulated at 9 on the console 6. The articulated lever 8 is designed to act, in turn, on the rod 4.

En fonctionnement, en l'absence de toute tension électrique appliquée à l'électro-aimant 7 la série de rondelles-ressorts métalliques provoque le blocage par l'élément de serrage 5 du disque 2 solidaire de l'axe à bloquer. In operation, in the absence of any electrical voltage applied to the electromagnet 7, the series of metal spring washers causes blocking by the clamping element 5 of the disc 2 secured to the axis to be blocked.

La mise sous tension de l'électro-aimant 7 provoque, par l'intermédiaire du levier 8, l'écrasement des rondelles entre la butée 3 de la tige 4 et la console 6 traversée par cette tige. L'écrasement des rondellesressorts autorise le dégagement du disque porté par ladite tige 4.  The energizing of the electromagnet 7 causes, via the lever 8, the crushing of the washers between the stop 3 of the rod 4 and the console 6 through which this rod passes. The crushing of the spring washers authorizes the disengagement of the disc carried by said rod 4.

Pour un meilleur serrage du disque par les rondelles-ressorts, l'élément de serrage 5 peut être équilibré dans son action par une cale 10 portée par la console en vis à vis du disque 2 et d'une épaisseur correspondant à l'épaisseur dudit disque 2. For better tightening of the disc by the spring washers, the clamping element 5 can be balanced in its action by a shim 10 carried by the console opposite the disc 2 and of a thickness corresponding to the thickness of said disc. disc 2.

Conformément à l'invention, lorsque les rondelles-ressorts sont mises en action, aucune rotation, même très faible, de l'axe A à bloquer n'est autorisée. Ceci est très important lorsque le positionnement du microscope a été effectué, tous les axes étant à l'état débloqué. According to the invention, when the spring washers are put into action, no rotation, even very slight, of the axis A to be blocked is authorized. This is very important when the positioning of the microscope has been carried out, all the axes being in the unlocked state.

Dans le cas, notamment du support du type trépied, il est indispensable que les bras horizontaux soient bloqués quand ledit trépied est roulé ou transféré sur chariot d'une salle à une autre par exemple. In the case, in particular of the tripod type support, it is essential that the horizontal arms are locked when said tripod is rolled or transferred on a carriage from one room to another for example.

Il est bien entendu, enfin, que la présente invention n'a été décrite et représentée qu'à titre d'exemple préférentiel et qu'on pourra apporter des équivalences dans ses éléments constitutifs sans, pour autant, sortir du cadre de l'invention qui est défini dans les revendications qui suivent.  It is understood, finally, that the present invention has only been described and shown as a preferred example and that it will be possible to provide equivalences in its constituent elements without, however, departing from the scope of the invention which is defined in the claims which follow.
