According to the invention, the foot rest is locked against rotation, in its service position, by means of a rotary cam which cooperates with the adjacent upright of the frame, this cam being locked by means of a locking finger. The cam and the locking finger are mounted on one of the lateral faces of the foot rest.

Description

L'invention est relative, notamment pour handicapés, equipé d'un dispositif pour verrouiller rapidement des repose-pied. Elle concerne plus précisément un fauteuil roulant dont le ou les repose-pied sont motés pivotants par rapport au châssis du fauteuil de façon à pouvoir être escamotés, et à faciliter ainsi l'accès au fauteuil ou le transport de celui-ci.The invention relates, in particular for the disabled, equipped with a device for quickly locking footrests. It relates more precisely to a wheelchair whose footrest (s) are pivoted relative to the frame of the chair so as to be able to be retracted, and thus to facilitate access to the chair or the transport thereof.

De préférence un repose-pied pivotant doit être verrouillé, au moins dans sa position de service, afin qu'il soit maintenu dans cette position et qu'il ne puisse pas pivoter inopinément. En outre, un tel verrouillage doit s'effectuer de manière simple et rapide.Preferably a pivoting footrest must be locked, at least in its service position, so that it is held in this position and that it cannot pivot unexpectedly. In addition, such locking must be carried out in a simple and rapid manner.

Un des buts de l'invention est donc de proposer un fauteuil équipé d'un dispositif pour verrouiller rapidement des repose-pied, dans leur position de service.One of the aims of the invention is therefore to propose an armchair equipped with a device for rapidly locking footrests, in their service position.

Un autre but de l'invention est de proposer un tel fauteuil dont les repose-pied sont fixés de façon démontable sur le châssis du fauteuil, le dispositif de verrouillage assurant aussi le maintien en position montée, des repose-pied sur le fauteuil.Another object of the invention is to provide such an armchair, the footrests of which are detachably fixed to the frame of the armchair, the locking device also ensuring that the footrest on the armchair is held in the mounted position.

L'invention concerne à cet effet un fauteuil comprenant un châssis monté sur roues, sur lequel est fixé de façon escamotable, au moins un repose-pied, qui peut pivoter par rapport au châssis selon un axe de pivotement sensiblement -perpendiculaire au plan d'appui du fauteuil roulant sur le sol.The invention relates to this effect a chair comprising a chassis mounted on wheels, on which is retractably fixed, at least one footrest, which can pivot relative to the chassis along a pivot axis substantially -perpendicular to the plane of wheelchair support on the floor.

Selon l'invention, le repose-pied comporte, sur une de ses faces latérales, un dispositif de verrouillage coopérant, en position de service du repose-pied, avec l'un des montants du châssis disposé sur le trajet du repose-pied, afin de verrouiller en rotation le repose-pied, le dispositif de verrouillage comprenant une came qui est montée à rotation par rapport à un axe parallèle à l'axe du montant et qui présente une surface latérale de coopération avec la surface latérale du montant, la came étant bloquée en position de coopération avec la surface latérale du montant au moyen d'un doigt de blocage monté sur le repose-pied, à proximité de la came.According to the invention, the footrest comprises, on one of its lateral faces, a cooperating locking device, in the operating position of the footrest, with one of the uprights of the frame disposed on the path of the footrest, in order to lock the footrest in rotation, the locking device comprising a cam which is rotatably mounted with respect to an axis parallel to the axis of the upright and which has a lateral surface for cooperation with the lateral surface of the upright, the cam being locked in position of cooperation with the lateral surface of the upright by means of a locking finger mounted on the footrest, near the cam.

De préférence, le doigt de blocage est monté à rotation par rapport à un axe parallèle à l'axe du montant, et est soumis élastiquement à un couple de rotation dans un sens donné, la came étant soumise élastiquement à un couple de rotation en sens inverse.Preferably, the locking finger is rotatably mounted relative to an axis parallel to the axis of the upright, and is subjected elastically to a torque in a given direction, the cam being elastically subjected to a torque to rotate reverse.

Avantageusement, le montant du châssis présente, dans sa région de coopération avec la came, une surface de forme cylindrique convexe, la came présentant en correspondance une surface de forme cylindrique concave.Advantageously, the amount of the chassis has, in its region of cooperation with the cam, a surface of convex cylindrical shape, the cam having in correspondence a surface of concave cylindrical shape.

En complément, la face latérale du repose-pied comportant le dispositif de verrouillage porte des moyens de butée qui, lorsque le repose-pied est verrouillé en rotation, sont plaqués contre des moyens de butée correspondants portés par le montant, pour immobiliser en translation le repose-pied selon la direction de l'axe de pivotement.In addition, the lateral face of the footrest comprising the locking device carries abutment means which, when the footrest is locked in rotation, are pressed against corresponding abutment means carried by the upright, to immobilize in translation the footrest in the direction of the pivot axis.

Ainsi, le repose-pied peut simplement être emmanché de façon coulissante et donc démontable sur un axe de pivotement solidaire du châssis, les moyens de butée précités assurant l'immobilisation du repose-pied le long de cet axe.Thus, the footrest can simply be slidably fitted and therefore removable on a pivot axis secured to the chassis, the abovementioned abutment means ensuring the immobilization of the footrest along this axis.

Selon un mode de réalisation préféré, le repose-pied comporte deux bras par l'extrémité desquels il est relié au châssis, ces deux bras étant sensiblement perpendiculaires à l'axe de pivotement et l'un d'eux portant le dispositif de verrouillage et les moyens de butée du repose-pied.According to a preferred embodiment, the footrest comprises two arms by the end of which it is connected to the chassis, these two arms being substantially perpendicular to the pivot axis and one of them carrying the locking device and the stop means of the footrest.

D'autres détails et avantages de l'invention apparaîtront au cours de la description qui suit, d'un mode de réalisation donné à titre d'exemple non limitatif, en regard des figures annexées, parmi lesquelles:

  • -la figure 1 est une vue en coupe longitudinale et en élévation d'un fauteuil roulant selon l'invention;
  • -la figure 2 est une vue en coupe selon la ligne II-II de la figure 1;
  • -la figure 3 est une vue en coupe selon la ligne III-III de la figure 2 ;
  • -la figure 4 est une vue en coupe selon la ligne IV-IV de la figure 2.
Other details and advantages of the invention will appear during the following description, of an embodiment given by way of nonlimiting example, with reference to the appended figures, among which:
  • FIG. 1 is a view in longitudinal section and in elevation of a wheelchair according to the invention;
  • FIG 2 is a sectional view along line II-II of Figure 1;
  • FIG 3 is a sectional view along line III-III of Figure 2;
  • FIG. 4 is a sectional view along the line IV-IV of FIG. 2.

Sur la figure 1 est représenté un fauteuil roulant 1 comprenant de façon connue en soi un châssis parallélépipédique 2 réalisé à l'aide de profilés assemblés par collage, vissage ou soudage. Le châssis 2 est monté sur quatre roues, à savoir deux grandes roues et deux roulettes 4. La figure 1 représente seulement le côté droit du fauteuil roulant coupé en deux dans sa longueur. La description relative à cette figure vaudra donc pour le côté gauche du fauteuil roulant.In Figure 1 is shown a wheelchair 1 comprising in a manner known per se a parallelepiped frame 2 produced using profiles assembled by gluing, screwing or welding. The chassis 2 is mounted on four wheels, namely two large wheels and two casters 4. Figure 1 shows only the right side of the wheelchair cut in half lengthwise. The description relating to this figure will therefore apply to the left side of the wheelchair.

Sur le montant avant droit 5 du châssis 2 est fixé un repose-pied 6 qui comprend principalement, et de façon connue en soi, une barre ou potence 7. A l'une des extrémités de la potence 7 est montée perpendiculairement une tablette 8 qui peut être rabattue contre la potence 7.On the right front upright 5 of the chassis 2 is fixed a footrest 6 which mainly comprises, and in a manner known per se, a bar or bracket 7. At one end of the bracket 7 is mounted perpendicularly a shelf 8 which can be folded against the stem 7.

Le repose-pied 6 comprend aussi de façon connue en soi deux bras 9,10 essentiellement non parallèles à la potence 7, qui sont distants l'un de l'autre et parallèles entre eux. Les deux bras 9,10 sont fixés par une extrémité sur la potence 7 et sont montés de façon pivotante par l'autre extrémité sur deux tétons respectifs 11,12 alignés sur un même axe géométrique de pivotement 13. L'axe de pivotement 13 est parallèle au montant avant 5 du châssis 2, c'est-à-dire perpendiculaire au plan d'appui du fauteuil roulant 1 sur le sol ; il est disposé en retrait par rapport à la face avant et au montant avant 5 du châssis 2, mais à l'extérieur du châssis 2 par rapport au côté droit de celui-ci.The footrest 6 also comprises, in a manner known per se, two arms 9, 10 essentially non-parallel to the stem 7, which are distant from each other and parallel to each other. The two arms 9, 10 are fixed by one end to the bracket 7 and are pivotally mounted by the other end on two respective studs 11, 12 aligned on the same geometric pivot axis 13. The pivot axis 13 is parallel to the front upright 5 of the chassis 2, that is to say perpendicular to the bearing plane of the wheelchair 1 on the ground; it is set back relative to the front face and to the front upright 5 of the chassis 2, but outside of the chassis 2 relative to the right side thereof.

Ainsi, le repose-pied 6 dans son ensemble peut tourner autour de l'axe de pivotement 13 pour être rabattu sur le côté droit du châssis 2. Lorsque le repose-pied 6 est en position de service, comme représenté sur les figures, son bras inférieur 9 vient buter contre le montant avant 5 qui est disposé sur le trajet de pivotement de ce bras.Thus, the footrest 6 as a whole can rotate around the pivot axis 13 to be folded down on the right side of the chassis 2. When the footrest 6 is in the service position, as shown in the figures, its lower arm 9 abuts against the front upright 5 which is disposed on the pivot path of this arm.

Selon l'invention, le-bras inférieur 9 du repose-pied 6 présente, dans sa partie centrale, une section en forme-du U (figure 3). Ses ailes 14,-t5 sont perpendiculaires à-l'axe de pivotement 13 et il est tourné, dans la position de service du repose-pied 6, vers le montant avant 5. Le bras inférieur 9 présente dans ses deux ailes 14, 15, du côté du téton 11, une échancrure 26 destinée à recevoir le montant avant 5.According to the invention, the lower arm 9 of the footrest 6 has, in its central part, a U-shaped section (Figure 3). Its wings 14, -t5 are perpendicular to the pivot axis 13 and it is turned, in the operating position of the footrest 6, towards the front upright 5. The lower arm 9 has in its two wings 14, 15 , on the side of the stud 11, a notch 26 intended to receive the upright before 5.

Entre les deux ailes 14, 15 du bras inférieur 9 et du côté du téton 11, est montée à rotation, autour d'un axe 16 qui la traverse dans sa partie centrale, une came 17. Son axe 16 est perpendiculaire aux ailes 14, 15 du bras inférieur 9, donc parallèle à l'axe du montant avant 5 et à l'axe de pivotement 13 du repose-pied 6. Cette came 17 présente une portion de surface latérale 18 qui est de forme cylindrique concave et qui est tournée vers le téton 11. Elle présente également un épaulement 19 de direction axiale qui est sensiblement diamétralement opposé à la portion cylindrique concave 18. La came 17 est soumise à un couple de rotation (dans le sens anti-horaire, tel que représenté en figure 2) au moyen d'un ressort de torsion 20 disposé sur un axe 21 parallèle à l'axe 16 de la came 17, entre cette came et la base 22 du bras inférieur 9. L'une des extrémités du ressort de torsion 20 s'appuie contre la came 17, et l'autre extrémité contre la base 22 du bras inférieur 9.Between the two wings 14, 15 of the lower arm 9 and on the side of the stud 11, a cam 17 is mounted for rotation about an axis 16 which passes through it in its central part. Its axis 16 is perpendicular to the wings 14, 15 of the lower arm 9, therefore parallel to the axis of the front upright 5 and to the pivot axis 13 of the footrest 6. This cam 17 has a portion of lateral surface 18 which is of concave cylindrical shape and which is turned towards the nipple 11. It also has a shoulder 19 of axial direction which is substantially diametrically opposite to the concave cylindrical portion 18. The cam 17 is subjected to a torque (in the counterclockwise direction, as shown in FIG. 2) ) by means of a torsion spring 20 disposed on an axis 21 parallel to the axis 16 of the cam 17, between this cam and the base 22 of the lower arm 9. One of the ends of the torsion spring 20 s' presses against the cam 17, and the other end against the base 22 of the lower arm 9.

A l'intérieur du bras inférieur 9 du repose-pied 6 et du côté de la potence 7, est aussi monté à rotation, selon un axe 24 perpendiculaire à ses ailes 14, 15, un doigt de blocage 23. Ce doigt de blocage 23 s'étend en longueur le long du bras inférieur 9, essentiellement du côté ouvert du bras inférieur 9. L'axe de rotation 24 du doigt de blocage 23, est disposé dans sa partie centrale, de sorte que le doigt de blocage 23 peut basculer autour de l'axe de rotation 24. Sur l'axe de rotation 24 est monté un ressort de torsion 25, de façon analogue à celui de la came 17, mais de telle sorte que le doigt de blocage 23 soit soumis à un couple de rotation dans le sens horaire (fig2).Inside the lower arm 9 of the footrest 6 and on the side of the bracket 7, is also mounted for rotation, along an axis 24 perpendicular to its wings 14, 15, a locking finger 23. This locking finger 23 extends lengthwise along the lower arm 9, essentially on the open side of the lower arm 9. The axis of rotation 24 of the locking finger 23, is arranged in its central part, so that the locking finger 23 can tilt around the axis of rotation 24. A torsion spring 25 is mounted on the axis of rotation 24, similar to that of the cam 17, but in such a way that the locking pin 23 is subjected to a torque clockwise rotation (fig2).

De cette façon, la came 17 et le doigt de blocage 23 sont amenés à pivoter l'un vers l'autre, l'extrémité du doigt de blocage 23 venant alors buter contre l'épaulement 19 de la came 17 ; ainsi, le doigt de blocage 23 et la came 17 se trouvent immobilisés.In this way, the cam 17 and the locking finger 23 are made to pivot towards one another, the end of the locking finger 23 then abutting against the shoulder 19 of the cam 17; thus, the locking finger 23 and the cam 17 are immobilized.

Le montant avant 5 du châssis présente, au moins dans sa région destinée à coopérer avec le bras inférieur 9, une section en forme générale de U. La base de ce U est arrondie de façon à former une portion de surface 27 de forme cylindrique convexe correspondant à la forme cylindrique concave de la portion cylindrique 18 de la came 17 précitée.The front upright 5 of the chassis has, at least in its region intended to cooperate with the lower arm 9, a section in the general shape of a U. The base of this U is rounded so as to form a surface portion 27 of cylindrical convex shape corresponding to the concave cylindrical shape of the cylindrical portion 18 of the aforementioned cam 17.

Par ailleurs, une goupille cylindrique 28 est montée en travers des deux ailes 29, 30 du montant avant 5. Elle dépasse du côté du montant destiné à coopérer avec le bras inférieur 9 du repose-pied 6. Le diamètre de la goupille 28 est légèrement inférieur à la distance séparant les deux ailes 14, 15 du bras inférieur 9.Furthermore, a cylindrical pin 28 is mounted across the two wings 29, 30 of the front upright 5. It protrudes from the side of the upright intended to cooperate with the lower arm 9 of the footrest 6. The diameter of the pin 28 is slightly less than the distance separating the two wings 14, 15 from the lower arm 9.

La came 17 et le doigt de blocage 23 décrits précédemment constituent un dispositif pour verrouiller le repose-pied 6 dans sa position de service représentée sur les figures. Afin d'effectuer ce verrouillage, on exerce tout d'abord une pression sur le doigt de blocage 23 de façon à dégager la came 17, laquelle tourne alors sur un certain angle, en vue de recevoir le montant avant 5. On rabat ensuite le repose-pied 6, depuis sa position d'escamotage dans laquelle il est disposé sur le côté du châssis 2, pour le placer en position de service. Dans ce mouvement, le montant avant 5 vient s'appliquer contre la portion cylindrique 18 de la came 17, et il entraîne celle-ci en rotation jusqu'à ce que les ailes 14, 15 du bras inférieur 9 butent contre le montant avant 5. Le relâchement du doigt de blocage 23 permet alors d'immobiliser la came 17 dans sa position finale.The cam 17 and the locking finger 23 described above constitute a device for locking the footrest 6 in its service position shown in the figures. In order to effect this locking, pressure is first exerted on the locking finger 23 so as to release the cam 17, which then rotates by a certain angle, in order to receive the front upright 5. The flap is then folded down. footrest 6, from its retracting position in which it is arranged on the side of the chassis 2, to place it in the service position. In this movement, the front upright 5 is applied against the cylindrical portion 18 of the cam 17, and it drives the latter in rotation up to that the wings 14, 15 of the lower arm 9 abut against the front upright 5. The release of the locking finger 23 then makes it possible to immobilize the cam 17 in its final position.

Le bras inférieur 9 est donc immobilisé en rotation, puisque la came 17 est appliquée à force contre le montant avant 5, par sa portion cylindrique 18.The lower arm 9 is therefore immobilized in rotation, since the cam 17 is forcibly applied against the front upright 5, by its cylindrical portion 18.

Pour déverrouiller le repose-pied 6, on exerce une pression sur le doigt de blocage 23 pour libérer la came 17, puis on pousse latéralement le repose-pied 6 de façon à l'éloigner du montant avant 5.To unlock the footrest 6, pressure is exerted on the locking finger 23 to release the cam 17, then the footrest 6 is pushed laterally so as to move it away from the front upright 5.

Selon l'invention, lorsque le bras inférieur 9 est rabattu contre le montant avant 5, il coiffe l'extrémité dépassante de la goupille 28 fixée en travers du montant avant 5. De cette façon, le bras inférieur 9, et donc l'ensemble du repose-pied 6, sont immobilisés en translation selon la direction de l'axe de pivotement 13 du repose-pied 6 : en effet, l'extrémité de la goupille 28 est disposée entre les deux ailes 14, 15 du bras inférieur 9 et ne peut se déplacer par rapport à ce bras. Les moyens de butée précités sont donc constitués, d'une part par la goupille 28, et d'autre part par les ailes 14, 15 du bras inférieur 9.According to the invention, when the lower arm 9 is folded against the front upright 5, it covers the protruding end of the pin 28 fixed across the front upright 5. In this way, the lower arm 9, and therefore the assembly of the footrest 6, are immobilized in translation along the direction of the pivot axis 13 of the footrest 6: in fact, the end of the pin 28 is disposed between the two wings 14, 15 of the lower arm 9 and cannot move relative to this arm. The abovementioned abutment means therefore consist, on the one hand, of the pin 28, and on the other hand, of the wings 14, 15 of the lower arm 9.

Naturellement, l'invention s'applique également à un repose-pied dont les" moyens dé liaison au châssis 2 ne sont pas des bras 9, 10 mais sont constitués par exemple par une paroi continue-qui s'étend le long de la 'puterrce. Dans ce cas, le dispositif de verrouillage est fixé sur cette paroi.Naturally, the invention also applies to a footrest whose "connecting means to the chassis 2 are not arms 9, 10 but are constituted for example by a continuous wall which extends along the ' In this case, the locking device is fixed to this wall.
