Description

CANNE SPECIALE POUR HANDICAPE PHYSIQUE SPECIAL ROD FOR PHYSICAL DISABLED
L'invention se rapporte au domaine des acces¬ soires de prothèse médicale. Elle concerne en particulier une canne pour handicapé physique dotée de moyens de jumelage.The invention relates to the field of medical prosthesis accessories. It relates in particular to a cane for the physically handicapped provided with twinning means.
Dans les accessoires de prothèse médicale il existe un article de grande diffusion appelé "Cannes Anglaises" réservées aux handicapés physiques. Ces "Cannes Anglaises" traditionnelles sont très mal équilibrées du fait de leur conformation et risquent souvent de glisser et de tomber par terre lorsqu'elles sont posées contre un point d'appui. Cela crée un problème pour l'utilisateur, handicapé physique, inévitablement limité dans ses mouve- ments et déplacements quand il est l'obligation de les poser. Le problème se pose dans une plus grande mesure lorsqu'il n'y a pas de point d'appui à proximité.In medical prosthesis accessories there is an article of wide distribution called "Cannes Anglaises" reserved for the physically handicapped. These traditional "English Rods" are very badly balanced because of their conformation and often risk slipping and falling to the ground when they are placed against a fulcrum. This creates a problem for the user, physically handicapped, inevitably limited in his movements and displacements when he is obliged to ask them. The problem arises to a greater extent when there is no fulcrum nearby.
En outre, le rangement des cannes après utilisa¬ tion devient un souci quotidien supplémentaire pour l'invalide alors qu'elles devraient au contraire être un produit d'assistance.In addition, the storage of canes after use becomes an additional daily concern for the disabled when they should instead be an assistance product.
L'inventeur à déjà proposé un type de canne répondant au problème exposé ci-dessus tel que décrit dans le certificat d'utilité FR 2.290886 publié le 11 juin 1976. La canne pour handicapé décrite, comprend un manche creux de section polygonale destiné à recevoir le manche de l'autre canne de forme correspondante mais légèrement infé¬ rieure de manière à assurer un jumelage de deux cannes. Ces cannes, au lieu de présenter un seul point d'appui au sol, sont réunies de telle façon qu'elles se présentent en un seul article avec 2 points d'appui au sol ayant ainsi une meilleure stabilité. En retournant les cannes jumelées, les deux accoudoirs présentent 4 points d'appui au sol suffi- sants pour assurer la stabilité de l'ensemble à même le sol, sans appui supplémentaire. Cette solution n'est que partiellement satisfai¬ sante sur le plan de la fabrication car elle nécessite la mise en oeuvre d'un moule pour chaque modèle; en outre, en cas de remplacement d'une canne dans un jeu de deux cannes, il faut tenir compte de l'appairage.The inventor has already proposed a type of cane responding to the problem described above as described in the utility certificate FR 2.290886 published on June 11, 1976. The cane for the disabled described, includes a hollow handle of polygonal section intended to receive the handle of the other rod of corresponding shape but slightly infé¬ higher so as to ensure a twinning of two rods. These rods, instead of having a single point of support on the ground, are combined in such a way that they are presented in a single article with 2 points of support on the ground, thus having better stability. By turning the twin rods upside down, the two armrests have 4 sufficient ground support points to ensure the stability of the assembly on the ground, without additional support. This solution is only partially satisfactory in terms of manufacturing since it requires the use of a mold for each model; in addition, if a rod is replaced in a set of two rods, pairing must be taken into account.
L'invention vise à fournir une canne spéciale d'un modèle unique permettent d'éviter les inconvénients ci-dessus énumérés.The invention aims to provide a special rod of a single model to avoid the drawbacks listed above.
A cet effet, l'invention a pour objet une canne pour handicapé comportant un manche de préhension sensible¬ ment horizontal; il se distingue en ce que le manche comporte en son extrémité des premiers moyens de raccorde- ment pouvant coopérer avec des moyens de raccordement seconds identiques aux premiers et situés sur l'extrémité du manche d'une deuxième canne en vue d'une solidarisation.To this end, the subject of the invention is a cane for the disabled comprising a handle that is substantially horizontal; it is distinguished in that the handle comprises at its end first connection means capable of cooperating with second connection means identical to the first and located on the end of the handle of a second rod for securing.
Ainsi, du fait de l'utilisation de moyens de raccordement identiques d'une canne à l'autre, on résout le problème de l'appairage des cannes et on facilite la fabrication puisqu'il existe un seul modèle.Thus, due to the use of identical connection means from one rod to the other, the problem of pairing the rods is solved and manufacturing is facilitated since there is only one model.
Selon l'invention, les moyens de raccordement comprennent au moins un couple d'éléments d'accrochage de formes complémentaires, premier et second, répartis sur la surface d'extrémité de la poignée de telle manière qu'il existe une correspondance entre chaque couple par rotation de 180° de celui-ci par rapport à un axe vertical médian de ladite surface.According to the invention, the connection means comprise at least a pair of hooking elements of complementary shapes, first and second, distributed over the end surface of the handle so that there is a correspondence between each pair. by 180 ° rotation thereof relative to a vertical median axis of said surface.
Selon un mode de réalisation de l'invention préféré, ledit couple est réparti sur la périphérie de ladite surface et l'accrochage s'effectue par rotation relative desdits premiers et seconds moyens de raccorde- ment, autour d'un axe orthogonal central à la surface de la poignée. Conformément au mode de réalisation préféré de l'invention, le premier élément d'accrochage comprend une gorge et un épaulement internes et le second élément d'accrochage comprend une gorge et un épaulement externes, l'épaulement du premier élément d'accrochage étant destiné à s'engager dans la gorge du second élément d'accrochage de moyens de raccordement seconds et vice versa.According to a preferred embodiment of the invention, said torque is distributed over the periphery of said surface and the attachment is effected by relative rotation of said first and second connection means, around an axis orthogonal central to the handle surface. According to the preferred embodiment of the invention, the first hooking element comprises an internal groove and a shoulder and the second hooking element comprises an external groove and a shoulder, the shoulder of the first hooking element being intended to engage in the groove of the second attachment element of second connection means and vice versa.
Selon une caractéristique de l'invention conforme au mode préféré de réalisation, les épaulements présentent une variation d'épaisseur, dans un même sens de rotation, afin d'assurer un blocage du raccordement par coincement dans les gorges correspondantes des éléments d'accrochage de moyens de raccordement seconds. Ainsi, un simple geste de rotation d'une canne par rapport à l'autre suffit à raccorder solidairement les deux cannes.According to a characteristic of the invention in accordance with the preferred embodiment, the shoulders have a variation in thickness, in the same direction of rotation, in order to ensure that the connection is blocked by wedging in the corresponding grooves of the hooking elements of second connection means. Thus, a simple gesture of rotation of a rod relative to the other is sufficient to connect the two rods together.
Avantageusement, les moyens de raccordement com- prennent un élément de centrage constitué par le bord d'un plateau central situé sur la surface SI, pour centrer les moyens de raccordement avant accrochage.Advantageously, the connection means comprise a centering element constituted by the edge of a central plate situated on the surface SI, for centering the connection means before hooking.
Cet élément de centrage facilite l'approche des deux cannes avant raccordement.This centering element facilitates the approach of the two rods before connection.
Selon un mode de réalisation préféré de 1'invention, les moyens de raccordement comprennent deux couples d'éléments d'accrochage, les éléments étant délimités par un angle au sommet O au plus égal à τt/4.According to a preferred embodiment of the invention, the connection means comprise two pairs of fastening elements, the elements being delimited by an apex angle O at most equal to τt / 4.
D'autres caractéristiques et avantages deOther features and benefits of
1'invention apparaîtront de la description qui va suivre d'un mode de réalisation, donné uniquement à titre d'exemple et de manière non limitative, en référence aux figures suivantes selon lesquelles: - la figure 1 représente une paire de cannes jumelées avec les moyens de raccordement selon 1'invention;The invention will appear from the following description of an embodiment, given solely by way of example and without limitation, with reference to the following figures according to which: - Figure 1 shows a pair of rods paired with the connection means according to the invention;
- la figure 2 représente une vue extérieure des moyens de raccordement;- Figure 2 shows an external view of the connection means;
- la figure 3 représente une coupe longitudinale de la figure 2 selon C-C.- Figure 3 shows a longitudinal section of Figure 2 along C-C.
On voit à la figure 1, que la canne (1) selon l'invention comportant un manche (2) de préhension est jumelée avec une autre canne (1') du même type par leur manche à l'aide de moyens de raccordement (3, 3') fixés à l'extrémité de leur manche.It can be seen in FIG. 1 that the cane (1) according to the invention comprising a handle (2) for gripping is paired with another cane (1 ') of the same type by their handle using connection means ( 3, 3 ') attached to the end of their handles.
Les moyens de raccordement sont identiques de manière à faciliter la fabrication et permettre un jumelage sans se préocuper de l'appairage d'origine.The connection means are identical so as to facilitate manufacture and allow pairing without worrying about the original pairing.
Selon l'invention, les moyens de raccordement sont conçus de manière à être biocables par rotation d'une canne par rapport à l'autre. Le blocage coïncide avec une configuration des deux cannes dans un même plan de manière à permettre une meilleure stabilité et une utilisation pra¬ tique des cannes ainsi jumelées. Ainsi, l'ensemble formée des deux cannes est équilibré et présente deux points d'appui (4, 4) sur le sol (5) .According to the invention, the connection means are designed so as to be biocable by rotation of one rod relative to the other. The blocking coincides with a configuration of the two rods in the same plane so as to allow better stability and practical use of the rods thus paired. Thus, the assembly formed by the two rods is balanced and has two support points (4, 4) on the ground (5).
Sur la figure 2 et 3, on voit un exemple de réalisation des moyens de raccordement (6) selon l'invention. L'extrémité de la poignée comprend une surface circulaire SI sur laquelle sont répartis uniformément des éléments d'accrochage et de blocage des cannes entre elles. Les éléments d'accrochage (7) sont saillants par rapport à la surface SI et s'étendent jusqu'au plan S2 parallèle à SI. Ces éléments sont de deux types et chaque type comprend des éléments d'accrochage de formes complé- mentaires aux formes des éléments d'accrochage de l'autre type. Ainsi les éléments d'accrochage d'une canne peuvent s'accrocher aux éléments d'accrochage complémentaires d'une autre canne. Les éléments d'accrochage sont constituées préfé- rentiellement par des gorges et des épaulements.In FIGS. 2 and 3, an exemplary embodiment of the connection means (6) according to the invention is seen. The end of the handle includes a circular surface SI on which are distributed hooking and blocking elements of the rods between them. The hooking elements (7) project from the surface SI and extend to the plane S2 parallel to SI. These elements are of two types and each type comprises hooking elements of shapes complementary to the shapes of the hooking elements of the other type. Thus the hooking elements of a rod can be hooked to the complementary hooking elements of another rod. The hooking elements preferably consist of grooves and shoulders.
Les éléments d'un premier type disposent d'une gorge interne (8) à fond cylindrique de rayon RI, les parois de la gorge étant constituées par la surface SI et la paroi d'un épaulement interne (9) dont l'épaisseur s'étend jusqu'à la surface S2. Sur l'exemple, la longueur respective de la gorge et de l'épaulement en arc de cercle est délimitée par un angle de centre 0 légèrement inférieur à τι/4 radians.The elements of a first type have an internal groove (8) with a cylindrical bottom of radius RI, the walls of the groove being constituted by the surface SI and the wall of an internal shoulder (9) whose thickness s 'extends to surface S2. In the example, the respective length of the groove and the shoulder in an arc is defined by an angle of center 0 slightly less than τι / 4 radians.
Les éléments d'un second type disposent d'une gorge externe (10) à fond cylindrique de rayon R3, les parois de la gorge étant constituées par la surface SI et la paroi d'un épaulement externe (11) dont l'épaisseur s'étend jusqu'à la surface S2.The elements of a second type have an external groove (10) with a cylindrical bottom of radius R3, the walls of the groove being constituted by the surface SI and the wall of an external shoulder (11) whose thickness s 'extends to surface S2.
De manière identique aux premiers éléments, les longueurs de la gorge et de l'épaulement sont délimités par un angle au sommet O légèrement inférieur à π/4 radians. Les épaulements présentent également à leur sommet une portion de surface cylindrique de rayon R2, R4. Les rayons RI et R2 sont respectivement légèrement supérieurs aux rayons R3, R4.Identically to the first elements, the lengths of the groove and the shoulder are delimited by an angle at the apex O slightly less than π / 4 radians. The shoulders also have a cylindrical surface portion of radius R2, R4 at their top. The rays RI and R2 are respectively slightly greater than the rays R3, R4.
Les moyens d'accrochage sont répartis sur une surface annulaire périphérique de la surface SI en laissant des zones libres délimitées par un angle au moins égal à π/4 radians entre deux éléments consécutifs.The attachment means are distributed over an annular peripheral surface of the surface SI, leaving free zones delimited by an angle at least equal to π / 4 radians between two consecutive elements.
La répartition est telle que les premiers éléments se trouvent en correspondance avec les seconds éléments par une rotation de 180° autour d'un axe vertical Y passant par le centre O.The distribution is such that the first elements are found in correspondence with the second elements by a rotation of 180 ° around a vertical axis Y passing through the center O.
L'exemple préféré comporte deux éléments d'accrochage d'un premier type diamétralement opposés et deux éléments d'accrochage du second type également opposés diamétralement. Toutefois, une solution également satisfai¬ sante consisterait à avoir des moyens de type complémen¬ taire diamétralement opposés. Il n'est pas exclu dans un mode de réalisation simplifié d'avoir uniquement une paire d'éléments d'accrochage plutôt que deux paires; dans ce cas, les éléments d'accrochage seraient délimités par les généra- trices d'un angle au plus égal à TE/2.The preferred example comprises two hooking elements of a first diametrically opposed type and two hooking elements of the second type also diametrically opposite. However, an equally satisfactory solution would consist in having means of the diametrically opposite complementary type. It is not excluded in a simplified embodiment to have only one pair of hooking elements rather than two pairs; in this case, the hooking elements would be delimited by the generators with an angle at most equal to TE / 2.
A contrario, il n'est pas exclu non plus d'avoir plus de deux paires d'élément d'accrochage.Conversely, it is not excluded either to have more than two pairs of hooking element.
Des moyens de blocage ou d'arrêt en position parallèle des cannes jumelées sont également prévues. Ils peuvent consister en plusieurs solutions à la portée de l'homme de l'art, tel qu'une butée, came, etc.Blocking or stopping means in parallel position of the twin rods are also provided. They can consist of several solutions within the reach of those skilled in the art, such as a stop, cam, etc.
La solution retenue et décrite ci-après consiste à réaliser une fonction telle qu'obtenue par un système du type vis/écrou. A cette fin, les épaulements des éléments d'accrochage présentent une épaisseur légèrement croissante dans un même sens de rotation afin d'assurer le blocage par coincement de ces derniers dans les gorges correspondantes décroissantes de moyens de raccordement seconds d'une autre canne. La variation de l'épaisseur s'effectue du côté de la gorge (visible sur la coupe C-C).The solution adopted and described below consists in performing a function as obtained by a system of the screw / nut type. To this end, the shoulders of the fastening elements have a slightly increasing thickness in the same direction of rotation in order to ensure the blocking by jamming of the latter in the corresponding decreasing grooves of second connection means of another rod. The thickness is varied on the side of the groove (visible on section C-C).
Les moyens de raccordement peuvent comprendre également des moyens de centrage pour faciliter le rappro¬ chement avec des moyens de raccordement seconds d'une autre canne. Ils sont constitués par une surface annulaire externe (13) d'un plateau central (14) présenté en sailli sur la surface SI. Le diamètre de l'anneau (13) est légère¬ ment inférieur ou au plus égal au diamètre inférieur déli¬ mitant des seconds éléments d'accrochage. Selon un mode de réalisation, la surface annu¬ laire du plateau comporte un excentrique se rapprochant des premiers éléments d'accrochage et formant une came (15). La position angulaire du rayon maximal de la came étant située juste avant la position angulaire de l'extrémité des premiers éléments. Ainsi, le plateau sert à la fois de moyen de centrage des moyens de raccordement et de moyen de blocage par coincement avec des portions de surface cylindrique inférieures des éléments.The connection means may also include centering means to facilitate approximation with second connection means of another rod. They consist of an external annular surface (13) of a central plate (14) presented projecting from the surface SI. The diameter of the ring (13) is slightly less than or at most equal to the smaller diameter delimiting second attachment elements. According to one embodiment, the annular surface of the plate has an eccentric approaching the first attachment elements and forming a cam (15). The angular position of the maximum radius of the cam being located just before the angular position of the end of the first elements. Thus, the plate serves both as a means of centering the connection means and as a means of locking by wedging with portions of lower cylindrical surface of the elements.
Avantageusement sur le plan technique, les moyens de raccordement sont constitués par 2 pièces strictement identiques d'où leur réalisation par un seul et même moule. Ainsi, un seul moule suffit pour réaliser en thermo-plas- tique moulé le manche muni à son extrémité des moyens de raccordement. Toutes les cannes (même les cannes uniques) seront munies de ce dispositif. On peut ainsi prévoir que dans certaines circonstances les cannes isolées pourront être raccordées à d'autres cannes isolées sans intervention particulière d'ajustage. Ce dispositif qui possède la très grande particularité de réunir ces 2 pièces ni droite, ni gauche, permet cette éventualité. La disposition jumelée des cannes constitue également un déambulateur simplifié à la portée immédiate de la main du handicapé. Advantageously from a technical point of view, the connection means consist of 2 strictly identical parts, hence their production by a single mold. Thus, a single mold is sufficient to produce in molded thermo-plastic the handle provided at its end with connection means. All rods (even single rods) will be fitted with this device. It can thus be provided that in certain circumstances the insulated rods may be connected to other insulated rods without any particular adjustment intervention. This device, which has the very special feature of bringing these 2 pieces together, neither right nor left, allows this possibility. The twin arrangement of canes is also a simplified walker within easy reach of the disabled.
