Le document FR-A-2 462 125 décrit un dispositif de blocage et d'équilibrage d'un plan de travail d'une table à dessiner, supporté par une colonne centrale coulissant dans un support comportant des moyens de guidage et reposant sur une plaque de base constitué par au moins deux patins de frein diamétralement opposés par rapport à l'axe géométrique de la colonne coulissante, constamment appuyés par des moyens mécaniques contre la surface intérieure de ladite colonne et par un vérin à gaz prenant appui par une de ses extrémités sur la plaque de base, par l'autre extrémité, munie d'une poulie, sur un câble, caractérisé par le fait qu'un dispositif de sécurité est constitué par une bascule dont le pivot est fixé environ à mi-hauteur du support de la colonne, un des leviers de la bascule étant traversé par une tige de commande des patins de frein et portant un des points d'accrochage du câble, l'autre point d'accrochage du câble étant situé sur le bas de la colonne, l'autre levier de la bascule étant relié à un ressort compensateur ayant son point de tension fixé sur ledit support.Document FR-A-2 462 125 describes a device for blocking and balancing a work surface of a drawing table, supported by a central column sliding in a support comprising guide means and resting on a plate basic consisting of at least two brake pads diametrically opposite with respect to the geometric axis of the sliding column, constantly pressed by mechanical means against the inner surface of said column and by a gas spring supported by one of its ends on the base plate, by the other end, provided with a pulley, on a cable, characterized in that a safety device is constituted by a rocker whose pivot is fixed approximately halfway up the support of the column, one of the lever levers being crossed by a control rod for the brake shoes and carrying one of the cable hooking points, the other cable hooking point being located on the bottom of the column, l other lever of the basc ule being connected to a compensating spring having its tension point fixed on said support.

Le but de l'invention consiste à réaliser un dispositif de sécurité plus simple, par conséquent moins onéreux qui réponde aux normes d'efficacité les plus strictes pour éviter une chute accidentelle de la planche en cas de défaillance des moyens d'équilibrage.The object of the invention is to provide a simpler safety device, therefore less expensive which meets the most stringent efficiency standards to avoid accidental fall of the board in the event of failure of the balancing means.

Le dispositif de sécurité selon l'invention est défini par la revendication 1.The safety device according to the invention is defined by claim 1.

Le verrou est une plaque d'une seule pièce formée de deux parties d'inégale largeur à partir d'une base linéaire commune, le décrochement comportant un des points d'attache d'un ressort l'autre étant sur le bâti, la partie la plus étroite, arrondie à son extrémité constituant un palpeur, la partie la plus large comportant, à l'opposé du palpeur, deux évidements superposés, l'un, le plus éloigné de la base linéaire, en forme de crochet, recevant la tringle de commande des moyens de blocage permanent de la colonne, l'autre, en forme d'encoche alignée sur l'axe de symétrie du palpeur, recevant une goupille de liaison du verrou avec la pédale de commande du desserrage desdits moyens de blocage.The lock is a single-piece plate formed from two parts of unequal width from a common linear base, the recess comprising one of the spring attachment points the other being on the frame, the part the narrowest, rounded at its end constituting a feeler, the widest part comprising, opposite the feeler, two superimposed recesses, one, the furthest from the linear base, in the form of a hook, receiving the rod for controlling the permanent blocking means of the column, the other, in the form of a notch aligned on the axis of symmetry of the probe, receiving a pin for connecting the lock with the pedal for controlling the loosening of said blocking means.

L'étrier supportant l'essieu de la première poulie de renvoi comporte, sur son axe de symétrie, un guide situé à une distance du fond de l'étrier inférieure à la largeur du palpeur du verrou.The stirrup supporting the axle of the first return pulley comprises, on its axis of symmetry, a guide located at a distance from the bottom of the stirrup less than the width of the feeler of the latch.

Un ressort, accroché d'une part au bâti d'autre part au verrou, exerce sur le verrou une force de traction nécessaire et suffisante pour maintenir l'extrémité arrondie du palpeur entre l'essieu de la première poulie de renvoi et le guide fixé sur l'étrier de façon qu'en cas de relâchement ou de rupture du câble, le verrou soit tiré par ledit ressort jusqu'à faire sortir de son encoche la goupille de liaison du verrou avec la pédale de commande.A spring, hooked on the one hand to the frame on the other hand to the bolt, exerts on the bolt a necessary and sufficient tensile force to maintain the rounded end of the probe between the axle of the first deflection pulley and the fixed guide on the caliper so that in the event of loosening or breaking of the cable, the lock is pulled by said spring until the lock connecting pin comes out of its notch with the control pedal.

Le dispositif arrête instantanément le mouvement de l'ensemble mobile dès qu'intervient une rupture du câble ou d'une autre pièce formant la chaîne cinématique de l'équilibrage.The device instantly stops the movement of the mobile assembly as soon as a break in the cable or another part forming the kinematic chain of balancing occurs.

En combinaison avec des moyens de mise à hauteur du plan de travail par un desserrage temporaire des mâchoires de frein enserrant la colonne, si le câble se rompt au cours de cette manoeuvre, le verrou entraîné par un ressort met la pédale de commande, hors d'action et le frein est immédiatement resserré.In combination with means for heightening the work surface by temporarily releasing the brake shoes surrounding the column, if the cable breaks during this maneuver, the lock driven by a spring puts the control pedal out of action. action and the brake is immediately applied.

La figure 1 représente une vue d'ensemble d'une table à dessin composée principalement d'un bâti 1, muni d'une embase 2, dans laquelle coulisse une colonne 3 supportant un plan de travail 4 par l'intermédiaire d'une ferrure d'orientation 5. Des moyens d'équilibrage du poids de l'ensemble mobile sont représentés en pointillés, pour mémoire. Les flèches a, b, c indiquent les trois orientations qui peuvent être données au plan de travail 4. Une pédale 6 située à l'extérieur du bâti juste au-dessus de l'embase 2 permet de desserrer les freins de blocage de la colonne mobile afin de mettre la table dans la position choisie. Ce dispositif de blocage est décrit dans le document No. 8216328.FIG. 1 represents an overall view of a drawing table mainly composed of a frame 1, provided with a base 2, in which slides a column 3 supporting a work surface 4 by means of a fitting orientation 5. Means for balancing the weight of the mobile assembly are shown in dotted lines, for the record. The arrows a, b, c indicate the three orientations which can be given to the work plan 4. A pedal 6 located outside the frame just above the base 2 makes it possible to release the blocking brakes of the column mobile in order to put the table in the chosen position. This locking device is described in document No. 8216328.

La figure 2 représente le dispositif de sécurité en place dans le bâti 1. Les moyens de blocage permanent de la colonne 3 sont constitués par un frein 7 constamment serré, dont le déblocage est commandé, au moyen d'une plaque 8 suspendue par deux ressorts 9 accrochés au bâti, par une pression sur la pédale 6 reliée à la plaque 8 par deux tringles 10, engagées du côté de la pédale dans un crochet 110 d'un verrou 11.Figure 2 shows the safety device in place in the frame 1. The permanent locking means of the column 3 are constituted by a brake 7 constantly applied, the release of which is controlled, by means of a plate 8 suspended by two springs 9 attached to the frame, by pressing the pedal 6 connected to the plate 8 by two rods 10, engaged on the side of the pedal in a hook 110 of a lock 11.

Les moyens d'équilibrage du poids de l'ensemble mobile - colonne 3 et plan de travail 4 - sont constitués par un ressort 12 accroché au bâti par un tendeur 120 réglable fixé sur une équerre 121, à l'opposé, le ressort 12 est accroché au bout 130 d'un câble 13.The means for balancing the weight of the mobile assembly - column 3 and work surface 4 - consist of a spring 12 hooked to the frame by an adjustable tensioner 120 fixed on a bracket 121, on the opposite, the spring 12 is attached to the end 130 of a cable 13.

Ce câble 13 passe dans la gorge 140 d'une première poulie de renvoi 14 puis dans la gorge hélicoïdale 150 d'une deuxième poulie de renvoi 15 pour venir s'accrocher par son autre bout 131 sur un crochet 300 fixé sur l'extrémité de la colonne 3 opposée à celle qui supporte le plan de travail 4.This cable 13 passes through the groove 140 of a first deflection pulley 14 then into the helical groove 150 of a second deflection pulley 15 to come and hang by its other end 131 on a hook 300 fixed on the end of the column 3 opposite to that which supports the work surface 4.

L'essieu 141 de la poulie 14 tourne librement dans un étrier 16 fixé sur le bâti 1 près de son embase 2 ; il n'est maintenu dans le fond 161 de l'étrier 16 que par la tension du câble 13. En cas de rupture dudit câble, l'essieu 141 sort de l'étrier par l'effet du poids de la poulie 14 puisque l'axe de symétrie AA de l'étrier 16 est vertical et que son ouverture 160 est orientée vers l'embase 2. Le support 151 de la poulie 15 est fixé sur le bâti 1 au point le plus éloigné de l'étrier 16 compatible avec la variation de hauteur prévue pour le positionnement du plan de travail par le coulissement de la colonne 3.The axle 141 of the pulley 14 rotates freely in a stirrup 16 fixed on the frame 1 near its base 2; it is only held in the bottom 161 of the stirrup 16 only by the tension of the cable 13. In the event of said cable breaking, the axle 141 leaves the stirrup by the effect of the weight of the pulley 14 since the the axis of symmetry AA of the stirrup 16 is vertical and that its opening 160 is oriented towards the base 2. The support 151 of the pulley 15 is fixed on the frame 1 at the point furthest from the stirrup 16 compatible with the variation in height provided for positioning the work surface by sliding column 3.

L'étrier 16 comporte sur l'axe AA un guide 162 situé à une distance de l'essieu (141) de la poulie 14, en place dans le fond 161 de l'étrier 16, déterminée par la largeur du palpeur 111 du verrou 11 et inférieure à celle-ci.The stirrup 16 has on the axis AA a guide 162 located at a distance from the axle (141) of the pulley 14, in place in the bottom 161 of the stirrup 16, determined by the width of the feeler 111 of the latch 11 and lower than this.

La figure 3 représente le verrou 11 qui assure la liaison entre l'essieu 141 de la première poulie de renvoi 14 et la pédale 6 de desserrage du frein 7.FIG. 3 represents the bolt 11 which provides the connection between the axle 141 of the first return pulley 14 and the pedal 6 for releasing the brake 7.

Ce verrou 11 est constitué par une plaque d'une seule pièce formée de deux parties 111, 112, d'inégale largeur à partir d'une base linéaire 113 commune, le décrochement 114 comportant un des points d'attache 115 d'un ressort 17, l'autre étant sur le bâti 1. La partie la plus étroite 111, arrondie à son extrémité libre 116, constitue un palpeur appuyé par la tension du ressort 17 entre le guide 162 et l'essieu 141 de la poulie 14.This lock 11 is constituted by a single-piece plate formed by two parts 111, 112, of unequal width from a common linear base 113, the recess 114 comprising one of the attachment points 115 of a spring 17, the other being on the frame 1. The narrowest part 111, rounded at its free end 116, constitutes a feeler supported by the tension of the spring 17 between the guide 162 and the axle 141 of the pulley 14.

La partie la plus large 112 comporte à l'opposé du palpeur 111, deux évidements 110, 117 superposés, l'un 110, le plus éloigné de la base linéaire 113, en forme de crochet, reçoit une des extrémités 100 de la tringle 10 de commande des moyens de blocage permanent de la colonne, le frein 7, l'autre extrémité 101 de la tringle 10 étant reliée à la plaque 8 de desserrage dudit frein. L'autre évidement, en forme d'encoche 110 alignée sur l'axe de symétrie BB du palpeur, reçoit une goupille 600 fixée sur la pédale 6, en deçà des points de pivotement 601 de celle-ci.The widest part 112 comprises, opposite the probe 111, two recesses 110, 117 superimposed, one 110, the most distant from the linear base 113, in the form of a hook, receives one of the ends 100 of the rod 10 for controlling the permanent blocking means of the column, the brake 7, the other end 101 of the rod 10 being connected to the plate 8 for releasing said brake. The other recess, in the form of a notch 110 aligned on the axis of symmetry BB of the probe, receives a pin 600 fixed on the pedal 6, below the pivot points 601 thereof.

La figure 4 représente l'action du verrou 11 en cas de rupture du câble 13.FIG. 4 represents the action of the latch 11 in the event of the cable 13 breaking.

La poulie 14 n'étant plus retenue par le câble 13 dans l'étrier 16, son essieu 141 est poussé vers l'ouverture 160 par l'action du palpeur 111 tiré par le ressort 17 sous le guide 162. Le verrou 11 effectue son recul dans le sens de la force F de traction du ressort 17 jusqu'au point de rencontre du décrochement 114 avec l'étrier 16. Ce déplacement du verrou 11 fait sortir la goupille 600 de son encoche 116 rompant la liaison avec la pédale 6. De ce fait, le desserrage du frein 7 ne peut avoir lieu et la colonne 3 reste bloquée dans sa position initiale sans rupture de pièce.The pulley 14 is no longer retained by the cable 13 in the stirrup 16, its axle 141 is pushed towards the opening 160 by the action of the feeler 111 pulled by the spring 17 under the guide 162. The latch 11 performs its recoil in the direction of the tensile force F of the spring 17 to the point where the recess 114 meets the stirrup 16. This movement of the lock 11 causes the pin 600 to come out of its notch 116 breaking the connection with the pedal 6. As a result, the release of the brake 7 cannot take place and the column 3 remains blocked in its initial position without breaking of the part.
