Abstract

The telescopic walking stick has two metal tubes (1,3) that can slide together automatically after a catch (13) is manually freed. The upper tube (1) has a coil spring (5) inside it that presses on plugs (6,16) whose inner parts have a dia. slightly greater than the inner dia. of the spring. A central rod (8), threaded at its extremities, is joined to the upper plug by lock nuts (9) and can slide freely in an opening through the lower plug (16). The catch has a stud (14) that engages in a hole (20) in the lower tube to lock the stick.

Description

La présente invention concerne une canne télescopique à rappel automatique,La plupart des handicapés des jambes ou de la colonie vertébrale éprouvent de grandes difficultés,étant assis,pour se relever. The present invention relates to a telescopic cane with automatic return. Most of the disabled legs or the spinal colony experience great difficulties, being seated, to get up.

Ils prennent l'habitudeten général,de se relever à l'aide de l'u de leurs mains en stappuyant sur le rebord arriere du siège,puis tentent de s'appuyer sur leur canne.Hélas,la poignée de celle-ci n'est pas à la hauteur convenable,d'où la difficulté qu'ils ont pour se lever. They usually get into the habit of getting up using the u of their hands while resting on the rear edge of the seat, then try to lean on their cane. Alas, the handle of it is not at the proper height, hence the difficulty they have in getting up.

La canne,dont la description va suivre,essaie de réduite cette difficulté.Certes,il existe une canne de ce genre,ou plutôt une béquille anglaise sur laquelle le constructeur a prévu la partie inférieure rétractable,donc raccourcissable,en appuyant sur un bouton sis dans la poignée.Mais ce dispositif ne semble pas donner satisfaction du fait du gros effort qu'il faut développer pour réduire la hauteur de la partie téle@copique.De plus sa conception semble trop complexe et donc d'un prix de revient élevé,dû au fai que le dispositif élastique est prévu avec un système hydraulique ou pneumatique. The cane, the description of which will follow, tries to reduce this difficulty. Certainly, there is a cane of this kind, or rather an English crutch on which the manufacturer has provided the retractable lower part, therefore shortenable, by pressing a sis button in the handle. But this device does not seem to be satisfactory because of the great effort that must be developed to reduce the height of the téle@copique part. Furthermore, its design seems too complex and therefore of a high cost price, due to the fact that the elastic device is provided with a hydraulic or pneumatic system.

Dans le système faisant ltobjet de la nouvelle conception,le dessin,ci-annexé,fera comprendre à titre d'exemple,comment cette canne peut être réalisée. In the system forming the object of the new design, the drawing, attached hereto, will show by way of example, how this rod can be produced.

La figure 1 est une vue de la canne à l'échelle 1/5e,montrant celle-ci avec l'indication CT représentant la course télescopique, ainsi que le dispositif de déverrouillage situé sensiblement à mihauteur. Figure 1 is a view of the rod at a 1 / 5th scale, showing it with the indication CT representing the telescopic stroke, as well as the unlocking device located substantially at mid-height.

La figure 2 est une coupe longitudinale de la canne,à échelle agrandie,montr nt le dispositif élastique à ressort à boudin,permettant facilement le télescopage de la partie inférieure,dès le déverrouillage d'un téton de blocage,monté sur basculeur élastique
Quant à la figure 3,de même échelle que la précédente,elle représente une variante possible du dispositif de verrouillage au m@ yen d'une lame élastique, en acier à ressort,dont le bouton formant tirette,est terminé par un téton similaire au précédent,dispositii dont le prix de revient serait inférieur. Figure 2 is a longitudinal section of the rod, on an enlarged scale, showing the elastic device with coil spring, allowing the telescoping of the lower part easily, as soon as a blocking pin is unlocked, mounted on an elastic rocker
As for FIG. 3, on the same scale as the previous one, it represents a possible variant of the locking device using a spring steel elastic blade, the pull button of which is terminated by a stud similar to the previous, dispositii whose cost price would be lower.

@@alis'e au moyen de deux tubes de métal léger,genre dur@lumin, (ont la partie runrieure 1 est terminée par une boucle à 180 formant poi@née,avec un embout 2 pouvant être en matière plastique. @@ alis'e by means of two tubes of light metal, kind hard @ lumin, (have the runrieure part 1 is terminated by a loop at 180 forming poi @ born, with an end piece 2 which can be made of plastic.

La partie inférieure 3 peut coulisser,avec un léger jeu,dans la partie supérieure.Un embout de caoutchouc 4 de modèle classiqueZest emboité à force dans la partie basse, l'instar de toutes les autre canne s. The lower part 3 can slide, with a slight play, in the upper part. A rubber end cap 4 of the classic model Z is force-fitted into the lower part, like all other rods.

Un ressort a boudin 5 dont les caractéristiques de pression peuvent être prévues différentes, suivant les désirs des usagers,es* adapté dans la partie supérieure et butte sur le centrage d'un embout 6 en nylon,rendu solidaire du tube par les vis 7.Une tige 8 est fixée dans cet embout,au moyen des écrous 9 et de la rondelle éventail 10. A coil spring 5 whose pressure characteristics can be provided different, according to the wishes of the users, es * adapted in the upper part and abuts on the centering of a nylon nozzle 6, made integral with the tube by the screws 7. A rod 8 is fixed in this end piece, by means of the nuts 9 and the fan washer 10.

Cette tige 8 peut coulisser librement dans la contre-pièce du ressort.La partie inférieure du tube 1 est dotée d'une bague formant collier 11 qui est fixée au moyen de la vis 12 formant axe d'articulation - du taquet-basculeur 13,dont la partie inférieure est dotée d'un téton cylindrique 14 et la partie supérieure d'un ressort de rappel 15 fixé par encastrement.Le taquet-basculeur,par son ressort, sollicite le téton 14 vers le tube inférieur 3 doté d'une contre-pièce 16,en nylon,formant butée inférieure du ressort 5,dont la fixation est assurée par les prisonniers 17,tandis que les écrous 18 bloqués par la rondelle-éventail 19 ,assurent sur la tige 8 la limitation de- course,vers le bRs,du tube 3.Ce dernier est muni,dans le haut,de l'orifice 20 assurant le verrouillage du tube par rapport à la partie supérieure,au moyen du tto 14.Ce dernier peut également s'encastrer dans l'orifice inférieur 21 légèrement calé par rapport @ l'orifice supérieur.Ce dispositif permet ainsi de maintenir le raccourcissement de la canne,pour être le cas écheant,logée dans une valise. This rod 8 can slide freely in the counter-piece of the spring. The lower part of the tube 1 is provided with a ring forming a collar 11 which is fixed by means of the screw 12 forming a hinge pin - of the rocker cleat 13, the lower part of which has a cylindrical stud 14 and the upper part of a return spring 15 fixed by embedding. The rocker cleat, by its spring, biases the stud 14 towards the lower tube 3 provided with a counter -piece 16, made of nylon, forming the lower stop of the spring 5, the fixing of which is ensured by the prisoners 17, while the nuts 18 blocked by the fan washer 19, ensure on the rod 8 the limitation of travel, towards the bRs, of the tube 3. The latter is provided, at the top, with the orifice 20 ensuring the locking of the tube relative to the upper part, by means of the tto 14. The latter can also be embedded in the lower orifice 21 slightly wedged in relation to the upper orifice. This device thus makes it possible to maintain the shortening of the cane, if necessary, housed in a suitcase.

Ainsi prévue,il suffit à l'utilisateur,assis sur un siège, d'appuyerspar exemple de la main gauche,sur le taquet-basculeur afin de rendre coulissable le tube inférieur et d'appuyer sur la poignée de la canne. Celle-ci va se raccourcir assez facilement sous la pression du bras droit,ce qui permettra à l'handicapé de se lever beaucoup plus facilement. Thus provided, it suffices for the user, seated on a seat, to press, for example with the left hand, on the rocker cleat in order to make the lower tube slide and to press on the handle of the cane. This will shorten quite easily under the pressure of the right arm, which will allow the disabled to get up much more easily.

Il va de soi que la canne,faisant l'objet de ce brevetspeut comporter une poignée rapportée en forme de té,préférée par certains handicapés.De meame que les dispositifs prévus peuvent,bien entendu,être appliqués à une béquille ou à une canne dite anglaise. It goes without saying that the cane, which is the subject of this patent, may include an attached handle in the shape of a tee, preferred by certain handicapped people. As well as the devices provided can, of course, be applied to a crutch or to a so-called cane English.
