Description

FLASQUE POUR FAUTEUIL ROULANT ET FAUTEUIL ROULANT ASSOCIE FLASK FOR WHEELCHAIR AND WHEELCHAIR
La présente invention concerne le domaine des fauteuils roulants, et porte en particulier sur un flasque pour fauteuil roulant et sur un fauteuil roulant associé. The present invention relates to the field of wheelchairs, and relates in particular to a wheelchair flange and a wheelchair associated.
Les flasques de protection pour fauteuil roulant, également appelés enjoliveurs, permettent de protéger les grandes roues de fauteuil roulant, et en particulier les rayons des grandes roues, contre les chocs. Ces flasques de protection permettent également aux personnes handicapées installées dans les fauteuils roulants de ne pas se coincer les doigts dans les rayons des grandes roues de fauteuil roulant. De plus, ces flasques de fauteuil roulant peuvent avoir des motifs décoratifs sur ceux-ci afin de permettre à la personne handicapée de personnaliser son fauteuil roulant .  The wheelchair shields, also known as hubcaps, help to protect large wheelchair wheels, especially the spokes of large wheels, against shocks. These protective flanges also allow people with disabilities in wheelchairs not to get their fingers caught in the shelves of large wheelchair wheels. In addition, these wheelchair flanges may have decorative motifs on them to allow the disabled person to customize his wheelchair.
Les flasques existants possèdent une forme circulaire bombée correspondant à la forme globale de l'ensemble de rayons de grande roue d'un fauteuil roulant, les flasques étant fixés aux rayons des roues par des systèmes de fixation, tels que des attaches de type Velcro®, des attaches de type Colson® et/ou des attaches de type rivet. Cependant, en raison de l'étape d'installation de ces systèmes de fixation, les personnes handicapées ne peuvent pas installer ou retirer facilement les flasques sur/de leur fauteuil roulant. De plus, cette étape d'installation des systèmes de fixation ne permet également pas à des personnes aidant les personnes handicapées d'installer facilement et rapidement les flasques sur les fauteuils roulants. The existing flanges have a convex circular shape corresponding to the overall shape of the set of wheel-chair spokes of a wheelchair, the flanges being fixed to the spokes of the wheels by fastening systems, such as fasteners Velcro type ® , Colson ® type fasteners and / or rivet type fasteners. However, due to the installation stage of these fasteners, people with disabilities can not easily install or remove the flanges on / from their wheelchair. In addition, this step of installation of fastening systems also does not allow people helping people with disabilities to install easily and quickly the flanges on wheelchairs.
La demande de modèle d'utilité japonais JP3108409U divulgue un enjoliveur de rayons pour fauteuil roulant, l'enjoliveur étant formé d'au moins deux éléments d'arc circulaire en matériau flexible qui ont une forme conique lorsqu'ils sont mutuellement assemblés, le diamètre de l'enjoliveur étant supérieur au diamètre de la main courante de roue de fauteuil roulant mais inférieur au diamètre de la roue, l'enjoliveur étant bombé et fixé aux rayons de la roue à l'aide de fixations passant à travers des trous de fixation réalisés dans l'enjoliveur, l'enjoliveur possédant en outre des encoches au niveau de sa circonférence en correspondance avec les pattes de fixation de la main courante afin d'ajuster la position de l'enjoliveur sur la roue. Cependant, cet enjoliveur ne peut pas être installé ou retiré facilement et rapidement par une personne handicapée, ou une personne aidant la personne handicapée, en raison de l'étape de fixation de l'enjoliveur sur les rayons de la roue, étape qui ne peut pas être réalisée par une personne handicapée installée dans le fauteuil roulant. De plus, l'étape d'assemblage des deux éléments de l'enjoliveur complique également l'installation de l'enjoliveur pour une personne handicapée. Japanese utility model application JP3108409U discloses a wheelchair wheel cover, the hubcap being formed of at least two elements circular arc of flexible material which have a conical shape when mutually assembled, the diameter of the hubcap being greater than the diameter of the wheelchair wheel handrail but less than the diameter of the wheel, the hubcap being curved and fixed to the spokes of the wheel with fasteners passing through the fixing holes made in the hubcap, the hubcap further having notches at its circumference in correspondence with the fastening tabs of the hand current to adjust the position of the hubcap on the wheel. However, this hubcap can not be installed or removed easily and quickly by a disabled person, or a person helping the disabled person, because of the stage of fixing the hubcap on the spokes of the wheel, a step that can not not be performed by a disabled person in the wheelchair. In addition, the assembly step of the two elements of the hubcap also complicates the installation of the hubcap for a disabled person.
La présente invention vise à résoudre les inconvénients de l'état de la technique, en proposant un flasque pour fauteuil roulant dont le bord externe est ondulé en une succession de creux et de bosses, le flasque étant flexible et portant une encoche radiale de saisie du flasque sur son bord externe au niveau de l'un des creux. Le flasque flexible peut ainsi être déformé par l'utilisateur pour insérer celui-ci derrière la main courante de roue, entre la main courante et la jante de la roue, les pattes de la main courante étant positionnées dans certains des creux du flasque, de telle sorte que, lorsque le flasque retourne dans sa forme plate non déformée après insertion, le flasque est maintenu en position contre la main courante, sans avoir besoin de fixer le flasque aux rayons de la roue, ce qui permet à une personne handicapée de facilement et rapidement installer/retirer le flaque sur/de son fauteuil roulant. The present invention aims to solve the drawbacks of the state of the art, by proposing a wheelchair flange whose outer edge is corrugated in a succession of hollows and bumps, the flange being flexible and bearing a radial notch for gripping the flange on its outer edge at one of the hollows. The flexible flange can thus be deformed by the user to insert it behind the wheel handrail, between the handrail and the rim of the wheel, the tabs of the handrail being positioned in some of the hollows of the flange, such that, when the flange returns to its undeformed flat shape after insertion, the flange is maintained in position against the handrail, without the need to attach the flange to the spokes of the wheel, which allows a disabled person to easily and quickly install / remove the puddle on / from his wheelchair.
La présente invention a donc pour objet un flasque configuré pour être adapté sur un fauteuil roulant ayant une paire de grandes roues et une paire de petites roues, une main courante étant fixée sur chaque grande roue, chaque main courante étant fixée sur la face externe de la jante de la grande roue correspondante par plusieurs pattes, caractérisé par le fait que le flasque possède une forme circulaire, le bord externe du flasque étant ondulé en une succession de creux et de bosses, le rayon du flasque au niveau des bosses étant configuré pour être compris entre le rayon du bord interne de la main courante et le rayon du bord externe de la main courante, le rayon du flasque au niveau des creux étant configuré pour correspondre à la distance entre le centre de la main courante et chaque patte, le flasque étant en outre flexible et portant une encoche radiale de saisie du flasque sur son bord externe au niveau de l'un des creux.  The present invention therefore relates to a flange configured to be adapted to a wheelchair having a pair of large wheels and a pair of small wheels, a handrail being fixed on each big wheel, each handrail being fixed on the outer face of the rim of the corresponding large wheel by several legs, characterized in that the flange has a circular shape, the outer edge of the flange being corrugated in a succession of hollows and bumps, the radius of the flange at the bumps being configured to be between the radius of the inner edge of the handrail and the radius of the outer edge of the handrail, the radius of the flange at the hollows being configured to correspond to the distance between the center of the handrail and each leg, the flange being further flexible and bearing a radial notch catching the flange on its outer edge at one of the recesses.
Ainsi, la forme spéciale du flasque permet à celui-ci d'être maintenu entre la jante et la main courante d'une grande roue de fauteuil roulant, sans avoir besoin de fixer le flasque aux rayons de la roue, ce qui permet à une personne handicapée de facilement et rapidement installer/retirer le flaque sur/de son fauteuil roulant. Le flasque flexible peut ainsi être saisi par l'utilisateur au niveau de son encoche radiale de saisie, puis être déformé par l'utilisateur pour insérer celui-ci derrière la main courante de la roue, les pattes de la main courante étant positionnées dans certains des creux du flasque, de telle sorte que, lorsque le flasque retourne dans sa forme plate non déformée, le flasque est maintenu en position contre la main courante . Thus, the special shape of the flange allows it to be maintained between the rim and the handrail of a large wheelchair wheel, without the need to fix the flange to the spokes of the wheel, which allows a disabled person to easily and quickly install / remove the puddle on / from his wheelchair. The flexible flange can thus be grasped by the user at its radial gripping notch, and then be deformed by the user to insert it behind the handrail of the wheel, the legs of the handrail being positioned in certain hollows of the flange, so that when the flange returns to its flat shape undeformed, the flange is held in position against the handrail.
Le flasque est ainsi facile à poser et à retirer pour ses potentiels utilisateurs, à savoir les personnes à mobilité réduite, toute personne handicapée dotée au minimum d'un bras valide étant en mesure de poser ou enlever seule le flasque de sa grande roue de fauteuil roulant .  The flange is thus easy to install and remove for its potential users, namely people with reduced mobility, any disabled person with at least one valid arm being able to install or remove the flange of his wheel chair rolling.
Le flasque est réalisé par découpage à 1 'emporte- pièce, le flasque étant destiné à être installé sur des roues munies d'une main courante fixée par un nombre quelconque de pattes.  The flange is made by punching one punch, the flange being intended to be installed on wheels provided with a handrail fixed by any number of legs.
En faisant coïncider certains des creux avec les pattes de la main courante, et en s 'aidant de l'encoche radiale de saisie pour passer un doigt à travers celle-ci afin de faire pression sur le flasque en vue de le déformer, le flasque s'emboîte au fur et à mesure des pressions exercées pour finir par passer derrière la main courante afin d'être retenu par celle-ci.  By making some of the recesses coincide with the tabs of the handrail, and by using the radial notch grip to pass a finger through it in order to pressure the flange to deform, the flange fits as pressure exerts to end up behind the handrail to be retained by it.
Les ondulations sur le bord externe du flasque permettent la souplesse du flasque et donc la torsion progressive du flasque de patte en patte afin de faire passer le flasque derrière la main courante, le flasque flexible retournant dans sa forme plate d'origine à la fin de l'installation.  The corrugations on the outer edge of the flange allow the flexibility of the flange and thus the progressive twisting of the leg flange flange to pass the flange behind the handrail, the flexible flange returning to its original flat shape at the end of installation.
Les formes et dimensions des pattes de main courante étant variées, par exemple de forme cylindrique ou plate, les creux du flasque sont dimensionnés de manière à pouvoir s'adapter à la plupart des pattes de main courante.  The shapes and dimensions of the handrail tabs being varied, for example of cylindrical or flat shape, the hollows of the flange are dimensioned so as to fit most of the tabs handrail.
Le flasque est, de préférence, conçu pour une roue de 24 pouces de fauteuil roulant d'adulte, mais pourrait également être conçu pour une roue de 20 ou 22 pouces de fauteuil roulant d'enfant ou de tout autre diamètre, sans s'écarter du cadre de la présente invention, l'homme du métier sachant sans problème adapter la taille du flasque en fonction des dimensions de la roue, pour obtenir l'effet de l'invention, à savoir un placement de certaines des pattes de la main courante dans des creux du flasque . The flange is, preferably, designed for a 24 inch adult wheelchair wheel, but could also be designed for a 20 or 22 inch wheel of a child wheelchair or other diameter, without departing from the scope of the present invention, the skilled person knowing without problem adapt the size of the flange depending on the size of the wheel, to obtain the effect of the invention, namely a placement of certain the legs of the handrail in the hollows of the flange.
Le flasque est retenu exclusivement par la main courante, le diamètre externe du flasque étant supérieur au diamètre interne de la main courante. Le diamètre du flasque doit donc être réduit, lors de l'installation, par déformation du flasque afin de faire passer le flasque derrière la main courante.  The flange is retained exclusively by the handrail, the outer diameter of the flange being greater than the internal diameter of the handrail. The diameter of the flange must be reduced, during installation, by deformation of the flange to pass the flange behind the handrail.
La première étape d'insertion du flasque consiste à placer un doigt dans l'encoche radiale de saisie, à savoir l'index pour une personne valide et le pouce pour une personne non valide depuis son fauteuil roulant, puis à réaliser à la fois une traction sur le flasque à l'aide du doigt inséré dans l'encoche et une pression sur le flasque à l'aide des autres doigts à gauche et à droite de l'encoche afin de déformer le flasque flexible pour réduire son diamètre, ce qui permet ainsi d'insérer le flasque derrière la main courante.  The first step of insertion of the flange is to place a finger in the radial notch of seizure, namely the index for a valid person and the thumb for an invalid person from his wheelchair, then to realize both a traction on the flange with the finger inserted in the notch and pressure on the flange with the other fingers to the left and right of the notch to deform the flexible flange to reduce its diameter, which allows to insert the flange behind the handrail.
Idéalement, et dans un soucis de confort d'installation du flasque, il est recommandé de placer l'axe radial de l'encoche radiale le plus perpendiculairement possible au sol, le creux situé à l'opposé de l'encoche radiale étant ainsi le premier creux à placer sur le bas de la roue contre la patte la plus proche du sol .  Ideally, and in the interests of comfort flange installation, it is recommended to place the radial axis of the radial notch as perpendicularly as possible to the ground, the hollow located opposite the radial notch being thus the first hollow to place on the bottom of the wheel against the paw closest to the ground.
Ensuite, grâce aux ondulations formées par les creux et les bosses sur le bord externe du flasque, le flasque s'insère facilement et progressivement au fur et à mesure de pressions de doigts sur le flasque au niveau des bosses en remontant à droite puis à gauche ou inversement vers le haut du flasque. Then, thanks to the undulations formed by the hollows and bumps on the outer edge of the flange, the flange easily and gradually inserts as finger pressures on the flange at the level of the flanges. bumps up to the right and then to the left or inversely to the top of the flange.
Il est à noter qu'une fois que l'utilisateur est habitué à manipuler le flasque, l'utilisateur sera apte à déformer de manière optimale le flasque afin de réduire au maximum son diamètre pour installer le flasque en un seul coup, le flasque se plaçant alors automatiquement derrière la main courante qui le retiendra.  It should be noted that once the user is used to handling the flange, the user will be able to deform optimally the flange to minimize its diameter to install the flange in one go, the flange is then automatically placing behind the handrail that will hold it.
Ainsi, une fois installé, le flasque permet de protéger la grande roue correspondante du fauteuil roulant, et en particulier les rayons de cette grande roue, contre les chocs. Le flasque permet également à la personne handicapée installée dans le fauteuil roulant de ne pas se coincer les doigts dans les rayons de grande roue du fauteuil roulant.  Thus, once installed, the flange can protect the wheel of the wheelchair, and especially the spokes of the big wheel, against shocks. The flange also allows the disabled person in the wheelchair not to get caught in the wheelchair spokes.
Le rayon du flasque au niveau des creux est de préférence compris entre 20 et 27 cm.  The radius of the flange at the hollows is preferably between 20 and 27 cm.
Le rayon du flasque au niveau des bosses est de préférence compris entre 21 et 28 cm.  The radius of the flange at the bumps is preferably between 21 and 28 cm.
Par forme circulaire, on entend que le bords à successions de creux et bosses du flasque est compris entre deux cercles centrés sur le centre du flasque (correspondant en utilisation au moyeu de la roue) , un cercle inscrit dans le flasque qui est tangent aux creux les plus prononcés du flasque, et un cercle circonscrit au flasque qui est tangent aux bosses les plus prononcées du flasque .  Circular shape means that the edges with successions of recesses and bumps of the flange is between two circles centered on the center of the flange (corresponding in use to the hub of the wheel), a circle inscribed in the flange which is tangent to the hollow the most pronounced of the flask, and a circle circumscribed to the flange which is tangent to the most prominent bumps of the flask.
Le rayon interne de la main courante correspond au plus faible rayon de la main courante.  The inner radius of the handrail is the smallest radius of the handrail.
Le rayon externe de la main courante correspond au plus grand rayon de la main courante.  The outer radius of the handrail is the largest radius of the handrail.
Selon une caractéristique particulière de l'invention, le flasque comprend en outre un trou central de moyeu configuré pour s'adapter sur un moyeu de grande roue . According to a particular characteristic of the invention, the flange further comprises a central hole hub configured to fit on a ferris wheel hub.
Ainsi, le trou central de moyeu est destiné à recevoir le moyeu de la grande roue de fauteuil roulant dans le cas où ledit moyeu est dans le plan de la main courante .  Thus, the central hub hole is intended to receive the hub of the wheelchair large wheel in the case where said hub is in the plane of the handrail.
Selon une caractéristique particulière de l'invention, la succession de creux et de bosses est uniformément répartie sur le bord externe du flasque.  According to a particular feature of the invention, the succession of hollows and bumps is uniformly distributed over the outer edge of the flange.
Ainsi, les positions de certains des creux sont en correspondance avec les positions des pattes de main courante lorsque le flasque est installé sur une grande roue de fauteuil roulant.  Thus, the positions of some of the recesses are in correspondence with the positions of the handrail tabs when the flange is installed on a large wheelchair wheel.
Selon une caractéristique particulière de l'invention, la succession de creux et de bosses est symétrique par rapport à un axe radial comprenant l'encoche radiale de saisie.  According to a particular characteristic of the invention, the succession of hollows and bumps is symmetrical with respect to a radial axis comprising the radial notch of gripping.
Selon une caractéristique particulière de l'invention, le rayon du flasque au niveau des deux bosses entourant l'encoche radiale de saisie est inférieur au rayon du flasque au niveau des autres bosses.  According to a particular characteristic of the invention, the radius of the flange at the two bumps surrounding the radial notch of entry is less than the radius of the flange at the other bumps.
Ainsi, les deux bosses entourant l'encoche radiale de saisie étant la dernière partie du flasque à passer sous la main courante, cela permet de faciliter le passage de cette dernière partie du flasque sous la main courante à la fin de l'installation.  Thus, the two bumps surrounding the radial notch input being the last part of the flange to pass under the handrail, it facilitates the passage of the latter part of the flange under the handrail at the end of the installation.
Le rayon du flasque au niveau des deux bosses entourant l'encoche radiale est de préférence de 25,30 cm.  The radius of the flange at the two bumps surrounding the radial notch is preferably 25.30 cm.
Selon une première variante de l'invention, le flasque comprend douze creux, dont le creux au niveau duquel est située l'encoche radiale de saisie, et douze bosses . Ainsi, cette première variante de flasque est spécialement conçue pour être installée sur une grande roue munie d'une main courante fixée par 4 ou 6 pattes. According to a first variant of the invention, the flange comprises twelve recesses, of which the hollow at which is located the radial notch of seizure, and twelve bumps. Thus, this first flange variant is specially designed to be installed on a large wheel provided with a handrail fixed by 4 or 6 legs.
Dans le cas où la main courante est fixée par 4 pattes, on utilise, pour recevoir les 4 pattes, deux axes radiaux du flasque comprenant chacun deux creux diamétralement opposés, dont de préférence l'axe radial de l'encoche radiale.  In the case where the handrail is fixed by 4 tabs, is used to receive the four tabs, two radial axes of the flange each comprising two diametrically opposed recesses, preferably the radial axis of the radial notch.
Dans le cas où la main courante est fixée par 6 pattes, on utilise, pour recevoir les 6 pattes, trois axes radiaux comprenant chacun deux creux diamétralement opposés, dont de préférence l'axe radial de l'encoche radiale .  In the case where the handrail is fixed by 6 legs, is used to receive the 6 legs, three radial axes each comprising two diametrically opposed recesses, preferably the radial axis of the radial notch.
Selon une seconde variante de l'invention, le flasque comprend dix creux, dont le creux au niveau duquel est située l'encoche radiale de saisie, et dix bosses.  According to a second variant of the invention, the flange comprises ten recesses, including the hollow at the level of which is located the radial notch of seizure, and ten bumps.
Ainsi, cette seconde variante de flasque est spécialement conçue pour être installée sur une grande roue munie d'une main courante fixée par 5 pattes.  Thus, this second variant flange is specially designed to be installed on a large wheel provided with a handrail fixed by 5 legs.
Dans le cas où la main courante est fixée par 5 pattes, on utilise, pour recevoir les 5 pattes, cinq creux du flasque, dont de préférence le creux situé à l'opposé de l'encoche radiale.  In the case where the handrail is fixed by 5 legs, five recesses of the flange are used to receive the legs, preferably the recess situated opposite the radial notch.
Selon une caractéristique particulière de l'invention, le flasque est en matière plastique.  According to a particular characteristic of the invention, the flange is made of plastic.
Ainsi, le flasque est à la fois souple pour permettre sa déformation par l'utilisateur et rigide pour lui permettre de revenir à sa forme plate initiale après la déformation .  Thus, the flange is both flexible to allow its deformation by the user and rigid to allow it to return to its original flat shape after the deformation.
Le flasque peut être de préférence en PVC The flange may be preferably PVC
(polychlorure de vinyle) 9/10. (polyvinyl chloride) 9/10.
Il est à noter que le flasque pourrait également être dans une autre matière plastique, par exemple du polycarbonate, tel que celui commercialisé sous la marque LEXAN® sans s'écarter du cadre de la présente invention. It should be noted that the flange could also be in another plastic material, for example polycarbonate, such as that sold under the trademark LEXAN ® without departing from the scope of the present invention.
Selon une caractéristique particulière de l'invention, le flasque comprend en outre un trou supplémentaire à proximité du trou central de moyeu, ledit trou supplémentaire étant configuré pour faciliter le démontage d'une grande roue démontable de fauteuil roulant par un utilisateur lorsque le flasque est installé sur ladite grande roue démontable.  According to a particular characteristic of the invention, the flange further comprises an additional hole near the central hub hole, said additional hole being configured to facilitate the dismounting of a large wheelchair wheel by a user when the flange is installed on said large removable wheel.
Les handicapés en fauteuil roulant étant actifs Disabled people in wheelchairs being active
(voyages, conduite, déplacements, sport, notamment handisport...) , ceux-ci sont de plus en plus amenés à utiliser des fauteuils dont les grandes roues sont très facilement démontables par simple pression sur le moyeu de la roue. Le trou central de moyeu et le trou supplémentaire à proximité du trou central de moyeu permettent cette manipulation de démontage. Le trou supplémentaire est dimensionné afin de permettre le passage de deux doigts de l'utilisateur (de préférence l'index et le majeur) qui permettront de faire pression avec le pouce sur le moyeu afin d'extraire facilement la roue du fauteuil. L'utilisateur peut ainsi saisir la roue à l'aide de ses deux doigts insérés dans le trou supplémentaire et appuyer sur le moyeu avec son pouce afin de démonter la roue. (travel, driving, travel, sport, especially handisport ...), they are increasingly brought to use chairs whose large wheels are easily removable by simply pressing on the hub of the wheel. The central hub hole and the additional hole near the central hub hole allow this disassembly manipulation. The additional hole is dimensioned to allow the passage of two fingers of the user (preferably the index and the major) which will make it possible to put pressure with the thumb on the hub in order to extract easily the wheel of the armchair. The user can seize the wheel with his two fingers inserted in the additional hole and press the hub with his thumb to disassemble the wheel.
Selon une caractéristique particulière de l'invention, au moins l'une des faces du flasque porte un motif décoratif.  According to a particular characteristic of the invention, at least one of the faces of the flange carries a decorative pattern.
Ainsi, l'utilisateur peut personnaliser son fauteuil roulant en choisissant le motif décoratif porté par les flasques.  Thus, the user can customize his wheelchair by choosing the decorative pattern carried by the flanges.
La présente invention a également pour objet un fauteuil roulant ayant une paire de grandes roues et une paire de petites roues, une main courante étant fixée sur chaque grande roue, chaque main courante étant fixée sur la face externe de la jante de la grande roue correspondante par plusieurs pattes, deux flasques tels que définis ci- dessous étant respectivement installés sur les deux grandes roues du fauteuil roulant, chaque patte de main courante étant reçue dans l'un des creux du flasque correspondant, chaque bord externe de flasque étant en appui contre le côté de la main courante correspondante en regard de la jante de la grande roue correspondante. The present invention also relates to a wheelchair having a pair of large wheels and a pair of small wheels, a handrail being fixed on each large wheel, each handrail being fixed on the outer face of the rim of the corresponding large wheel by several legs, two flanges as defined below being respectively installed on the two large wheels of the wheelchair, each leg of the handrail being received in one of the recesses of the corresponding flange, each outer flange edge being in abutment against the side of the corresponding handrail opposite the rim of the corresponding large wheel.
Pour mieux illustrer l'objet de la présente invention, on va en décrire ci-après, à titre illustratif et non limitatif, deux variantes d'un mode de réalisation préféré, avec référence aux dessins annexés.  To better illustrate the object of the present invention will be described below, by way of illustration and not limited to two variants of a preferred embodiment, with reference to the accompanying drawings.

Si l'on se réfère à la Figure 1, on peut voir qu'il y est représenté un flasque 1 pour fauteuil roulant selon une première variante de l'invention. Le flasque 1 possède une forme sensiblement circulaire, le flasque 1 étant plat lorsqu'il n'est pas déformé par un utilisateur pour son installation. With reference to FIG. 1, it can be seen that there is shown a flange 1 for a wheelchair according to a first variant of the invention. The flange 1 has a substantially circular shape, the flange 1 being flat when not deformed by a user for its installation.
Le bord externe du flasque 1 est ondulé en une succession de creux Al à A12 et de bosses Bl à B12.  The outer edge of the flange 1 is corrugated in a succession of recesses A1 to A12 and bumps B1 to B12.
Le flasque 1 est en outre flexible et porte une encoche radiale de saisie 2 du flasque 1 sur son bord externe au niveau de l'un A12 des creux Al à A12.  The flange 1 is furthermore flexible and has a radial gripping notch 2 of the flange 1 on its outer edge at the level of one A12 of the recesses A1 to A12.
Le flasque 1 comprend en outre un trou central de moyeu 3 destiné à recevoir un moyeu de grande roue de fauteuil roulant lorsque le flasque 1 est installé sur une grande roue de fauteuil roulant, le trou central de moyeu 3 ayant de préférence une forme circulaire.  The flange 1 further comprises a central hub hole 3 for receiving a wheelchair wheel hub hub when the flange 1 is installed on a large wheelchair wheel, the central hub hole 3 preferably having a circular shape.
Il est à noter que le flasque 1 pourrait ne pas comprendre de trou central de moyeu 3, sans s'écarter du cadre de la présente invention.  It should be noted that the flange 1 may not include a central hub hole 3, without departing from the scope of the present invention.
Selon la première variante de l'invention, le flasque 1 comprend douze creux Al à A12, dont le creux A12 au niveau duquel est située l'encoche radiale de saisie 2, et douze bosses Bl à B12.  According to the first variant of the invention, the flange 1 comprises twelve recesses Al to A12, the recess A12 at which is located the radial notch of entry 2, and twelve bumps Bl to B12.
La succession de creux Al à A12 et de bosses Bl à B12 est uniformément répartie sur le bord externe du flasque 1, et est symétrique par rapport à l'axe radial comprenant l'encoche radiale de saisie 2.  The succession of troughs A1 to A12 and bumps B1 to B12 are uniformly distributed over the outer edge of the flange 1, and is symmetrical with respect to the radial axis comprising the radial gripping notch 2.
Ainsi, cette première variante du flasque 1 est spécialement conçue pour être installée sur une grande roue de fauteuil roulant munie d'une main courante fixée par quatre ou six pattes à la jante de la grande roue.  Thus, this first variant of the flange 1 is specially designed to be installed on a large wheelchair wheel provided with a handrail fixed by four or six legs to the rim of the ferris wheel.
Dans le cas où la main courante est fixée par quatre pattes, on utilise, pour recevoir les quatre pattes, deux axes radiaux du flasque 1 comprenant chacun deux creux diamétralement opposés, dont de préférence l'axe radial de l'encoche radiale 2. Ainsi, les creux A3, A6 , A9 et A12 sont de préférence utilisés pour recevoir les quatre pattes de la main courante. In the case where the handrail is fixed by four legs, is used, to receive the four legs, two radial axes of the flange 1 each comprising two diametrically opposed recesses, preferably the radial axis of the radial notch 2. Thus , troughs A3, A6, A9 and A12 are preferably used to receive the four legs of the handrail.
Dans le cas où la main courante est fixée par six pattes, on utilise, pour recevoir les six pattes, trois axes radiaux comprenant chacun deux creux diamétralement opposés, dont de préférence l'axe radial de l'encoche radiale 2. Ainsi, les creux A2 , A4, A6 , A8 , A10 et A12 sont de préférence utilisés pour recevoir les six pattes de la main courante .  In the case where the handrail is fixed by six legs, is used, to receive the six legs, three radial axes each comprising two diametrically opposed recesses, preferably the radial axis of the radial notch 2. Thus, the hollow A2, A4, A6, A8, A10 and A12 are preferably used to receive the six legs of the handrail.
Le rayon du flasque 1 au niveau des deux bosses The radius of the flange 1 at the two bumps
Bl et B12 entourant l'encoche radiale de saisie 2 est inférieur au rayon du flasque 1 au niveau des autres bosses B2 à Bll. B1 and B12 surrounding the radial entry notch 2 is less than the radius of the flange 1 at the other bumps B2 to B11.
Ainsi, l'ensemble constitué par les deux bosses Bl et B12 entourant l'encoche radiale de saisie 2 étant la dernière partie du flasque 1 à passer derrière la main courante lors de l'installation du flasque 1, cela permet de faciliter le passage de cette dernière partie du flasque 1 derrière la main courante à la fin de l'installation.  Thus, the assembly constituted by the two bumps Bl and B12 surrounding the radial gripping notch 2 being the last part of the flange 1 to pass behind the handrail during the installation of the flange 1, this facilitates the passage of this last part of the flange 1 behind the handrail at the end of the installation.
Le rayon du flasque 1 au niveau des creux Al à The radius of the flange 1 at the level of the troughs Al to
Ail est de préférence de 24,85cm. Garlic is preferably 24.85cm.
Le rayon du flasque 1 au niveau de l'encoche radiale de saisie 2 est de préférence de 21,45 cm.  The radius of the flange 1 at the radial gripping slot 2 is preferably 21.45 cm.
Le rayon du flasque 1 au niveau des bosses B2 à Bll est de préférence de 25,85 cm.  The radius of the flange 1 at the bosses B2 to B11 is preferably 25.85 cm.
Le rayon du flasque 1 au niveau des deux bosses Bl et B12 entourant l'encoche radiale 2 est de préférence de 25,52 cm.  The radius of the flange 1 at the two bumps Bl and B12 surrounding the radial notch 2 is preferably 25.52 cm.
Il est à noter que l'une des faces du flasque 1 pourrait également porter un motif décoratif afin que l'utilisateur puisse personnaliser son fauteuil roulant, sans s'écarter du cadre de la présente invention, le motif décoratif étant destiné à être tourné à l'opposé des rayons de la roue. It should be noted that one of the faces of the flange 1 could also carry a decorative pattern so that the user can customize his wheelchair, without departing from the scope of the present invention, the pattern decorative being intended to be turned away from the spokes of the wheel.
Si l'on se réfère à la Figure 2, on peut voir qu'il y est représenté un flasque 4 pour fauteuil roulant selon une seconde variante de l'invention.  With reference to FIG. 2, it can be seen that there is shown a flange 4 for a wheelchair according to a second variant of the invention.
Le flasque 4 selon la seconde variante est identique au flasque 1 selon la première variante à l'exception du fait que le flasque 4 selon la seconde variante comprend dix creux Cl à C10, dont le creux C10 au niveau duquel est située l'encoche radiale de saisie 2, et dix bosses Dl à D10.  The flange 4 according to the second variant is identical to the flange 1 according to the first variant except that the flange 4 according to the second variant comprises ten recesses C1 to C10, the hollow C10 at which is located the radial notch input 2, and ten bumps D1 to D10.
Ainsi, cette seconde variante du flasque 4 est spécialement conçue pour être installée sur une grande roue de fauteuil roulant munie d'une main courante fixée par cinq pattes à la jante de la grande roue.  Thus, this second variant of the flange 4 is specially designed to be installed on a large wheelchair wheel provided with a handrail fixed by five legs to the rim of the ferris wheel.
Dans le cas où la main courante est fixée par cinq pattes, on utilise, pour recevoir les cinq pattes, cinq creux du flasque 4, dont de préférence le creux C5 situé à l'opposé de l'encoche radiale 2. Ainsi, les creux Cl, C3 , C5, C7 et C9 sont de préférence utilisés pour recevoir les cinq pattes de la main courante.  In the case where the handrail is fixed by five legs, five recesses of the flange 4 are used to receive the five legs, preferably the recess C5 situated opposite the radial notch 2. Thus, the recesses C1, C3, C5, C7 and C9 are preferably used to receive the five legs of the handrail.
Le rayon du flasque 4 au niveau des deux bosses Dl et D10 entourant l'encoche radiale de saisie 2 est inférieur au rayon du flasque 4 au niveau des autres bosses D2 à D9.  The radius of the flange 4 at the two bumps D1 and D10 surrounding the radial groove 2 is less than the radius of the flange 4 at the other bumps D2 to D9.
Le rayon du flasque 4 au niveau des creux Cl à C9 est de préférence de 24,85 cm.  The radius of the flange 4 at the recesses C1 to C9 is preferably 24.85 cm.
Le rayon du flasque 4 au niveau de l'encoche radiale de saisie 2 est de préférence de 21,45 cm.  The radius of the flange 4 at the radial gripping slot 2 is preferably 21.45 cm.
Le rayon du flasque 4 au niveau des bosses D2 à The radius of the flange 4 at the level of the bosses D2 to
D9 est de préférence de 25,85 cm. Le rayon du flasque 4 au niveau des deux bosses Dl et D10 entourant l'encoche radiale 2 est de préférence de 25,52 cm. D9 is preferably 25.85 cm. The radius of the flange 4 at the two bumps D1 and D10 surrounding the radial notch 2 is preferably 25.52 cm.
Le flasque 4 comprend en outre un trou supplémentaire 5 à proximité du trou central de moyeu 3, ledit trou supplémentaire 5 étant configuré pour faciliter le démontage d'une grande roue démontable de fauteuil roulant par un utilisateur lorsque le flasque 4 est installé sur ladite grande roue démontable, le trou supplémentaire 5 ayant de préférence une forme de haricot.  The flange 4 further comprises an additional hole 5 near the central hub hole 3, said additional hole 5 being configured to facilitate the dismounting of a large wheelchair wheel by a user when the flange 4 is installed on said large removable wheel, the additional hole 5 preferably having a bean form.
Le trou supplémentaire 5 est dimensionné afin de permettre le passage de deux doigts de l'utilisateur (de préférence l'index et le majeur) qui permettront de faire pression avec le pouce sur le moyeu afin d'extraire facilement la roue du fauteuil, de manière classique pour une roue démontable. L'utilisateur peut ainsi saisir la roue à l'aide de ses deux doigts insérés dans le trou supplémentaire 5 et appuyer sur le moyeu avec son pouce afin de démonter la roue, sans avoir à ôter le flasque installé.  The additional hole 5 is dimensioned to allow the passage of two fingers of the user (preferably the index finger and the middle finger) which will make it possible to press with the thumb on the hub in order to easily extract the wheel from the chair, from classic way for a demountable wheel. The user can thus grasp the wheel with his two fingers inserted in the additional hole 5 and press the hub with his thumb to disassemble the wheel, without having to remove the flange installed.
Il est à noter que le flasque 4 pourrait ne pas comprendre de trou supplémentaire 5, sans s'écarter du cadre de la présente invention. De même, la première variante du flasque 1 représentée en Figure 1 pourrait comprendre ce trou 5 si le flasque 1 est destiné à être utilisé sur une grande roue démontable.  It should be noted that the flange 4 may not include an additional hole 5, without departing from the scope of the present invention. Similarly, the first variant of the flange 1 shown in Figure 1 could include this hole 5 if the flange 1 is intended to be used on a large removable wheel.
Si l'on se réfère à la Figure 3, on peut voir qu'il y est représenté le flasque 1 flexible, selon la première variante de l'invention, déformé par un utilisateur.  Referring to Figure 3, it can be seen that there is shown the flange 1 flexible, according to the first embodiment of the invention, deformed by a user.
Le flasque 1 est en matière plastique.  The flange 1 is made of plastic.
Le flasque 1 est ainsi à la fois souple pour permettre sa déformation par l'utilisateur et rigide pour lui permettre de revenir à sa forme plate initiale après la déformation . The flange 1 is thus both flexible to allow its deformation by the user and rigid for allow it to return to its original flat shape after deformation.
Le flasque 1 est de préférence en PVC (polychlorure de vinyle) 9/10.  The flange 1 is preferably PVC (polyvinyl chloride) 9/10.
II est à noter que le flasque 1 pourrait également être dans une autre matière plastique, par exemple du polycarbonate commercialisé sous la marque LEXAN®, sans s'écarter du cadre de la présente invention. It should be noted that the flange 1 could also be in another plastic material, for example polycarbonate sold under the trademark LEXAN ® , without departing from the scope of the present invention.
Le flasque 1 est réalisé par découpage à l'emporte-pièce, sans que cette technique soit limitative. Il pourrait ainsi par exemple être découpé par laser.  The flange 1 is made by die cutting, without this technique being limiting. It could for example be cut by laser.
Tel que représenté à la Figure 3, le flasque 1 flexible peut ainsi être saisi par une main de l'utilisateur au niveau de l'encoche radiale de saisie 2 du flasque 1, puis être déformé par l'utilisateur.  As represented in FIG. 3, the flexible flange 1 can thus be gripped by a user's hand at the level of the radial gripping notch 2 of the flange 1, and then be deformed by the user.
Le diamètre du flasque 1 est ainsi réduit par déformation du flasque 1, formant une sorte de dôme, afin de faire passer le flasque 1 derrière la main courante lors de l'installation.  The diameter of the flange 1 is thus reduced by deformation of the flange 1, forming a kind of dome, to pass the flange 1 behind the handrail during installation.
La première étape d'installation du flasque 1 consiste donc à placer un doigt 6a dans l'encoche radiale de saisie 2, à savoir l'index pour une personne valide et le pouce pour une personne non valide depuis son fauteuil roulant, puis à réaliser à la fois une traction sur le flasque 1 à l'aide du doigt 6a inséré dans l'encoche 2 et une pression sur le flasque 1 à l'aide des autres doigts 6b à gauche et à droite de l'encoche 2 afin de déformer le flasque 1 flexible pour réduire son diamètre, ce qui permet ainsi d'insérer le flasque 1 derrière la main courante.  The first step of installation of the flange 1 is therefore to place a finger 6a in the radial notch of entry 2, namely the index for a valid person and the thumb for an invalid person from his wheelchair, then to achieve both a traction on the flange 1 with the finger 6a inserted in the notch 2 and a pressure on the flange 1 with the other fingers 6b left and right of the notch 2 to deform the flange 1 flexible to reduce its diameter, which allows to insert the flange 1 behind the handrail.
Si l'on se réfère aux Figures 4 et 5, on peut voir qu'il y est représenté le flasque 1 installé sur une grande roue 7 de fauteuil roulant. La grande roue 7 de fauteuil roulant comprend une jante 8 sur laquelle est monté un pneu 9, des rayons (non représentés aux Figures 4 et 5) étant disposés radialement vers le centre de la jante 8 jusqu'à un moyeu 10. Referring to Figures 4 and 5, it can be seen that there is shown the flange 1 installed on a wheel wheel 7 wheel. The large wheel 7 wheelchair includes a rim 8 on which is mounted a tire 9, spokes (not shown in Figures 4 and 5) being arranged radially towards the center of the rim 8 to a hub 10.
Une main courante 11 est fixée sur la roue 7, la main courante 11 étant fixée sur la face externe de la jante 8 de la roue 7 par six pattes 12.  A handrail 11 is fixed on the wheel 7, the handrail 11 being fixed on the outer face of the rim 8 of the wheel 7 by six lugs 12.
Il est à noter que la main courante 11 pourrait également être fixée par au moins deux pattes 12, sans s'écarter du cadre de la présente invention.  It should be noted that the handrail 11 could also be fixed by at least two lugs 12, without departing from the scope of the present invention.
Le rayon du flasque 1 au niveau des bosses Bl à B12 est compris entre le rayon du bord interne lia de la main courante 11 et le rayon du bord externe 11b de la main courante 11.  The radius of the flange 1 at the bumps Bl to B12 is between the radius of the inner edge 11a of the handrail 11 and the radius of the outer edge 11b of the handrail 11.
Le rayon du flasque 1 au niveau des creux Al à The radius of the flange 1 at the level of the troughs Al to
Ail correspond sensiblement à la distance entre le centre de la main courante 11 et chaque patte 12. Garlic substantially corresponds to the distance between the center of the handrail 11 and each leg 12.
Ainsi, la forme spéciale du flasque 1 permet à celui-ci d'être maintenu entre la jante 8 et la main courante 11 de la roue 7 de fauteuil roulant, sans avoir besoin de fixer le flasque 1 aux rayons de la roue 7, ce qui permet à une personne handicapée de facilement et rapidement installer/retirer le flaque 1 sur/de son fauteuil roulant. Le flasque 1 flexible peut ainsi être saisi par l'utilisateur au niveau de son encoche radiale de saisie 2, puis être déformé par l'utilisateur pour insérer celui-ci derrière la main courante 11 de la roue 7, les pattes 12 de la main courante 11 étant positionnées dans certains des creux A2 , A4, A6 , A8 , A10 et A12 du flasque 1, de telle sorte que, lorsque le flasque 1 retourne dans sa forme plate non déformée, le flasque 1 est maintenu en position contre la main courante 11. Le flasque 1 est ainsi facile à poser et à retirer pour ses potentiels utilisateurs à savoir les personnes à mobilité réduite, toute personne handicapée dotée au minimum d'un bras valide étant en mesure de poser ou enlever seule le flasque 1 de la roue 7 de fauteuil roulant . Thus, the special shape of the flange 1 allows it to be maintained between the rim 8 and the handrail 11 of the wheel 7 wheelchair, without the need to fix the flange 1 to the spokes of the wheel 7, this which allows a disabled person to easily and quickly install / remove the spill 1 on / from his wheelchair. The flexible flange 1 can thus be grasped by the user at its radial gripping slot 2, and then deformed by the user to insert it behind the handrail 11 of the wheel 7, the legs 12 of the hand current 11 being positioned in some of the recesses A2, A4, A6, A8, A10 and A12 of the flange 1, so that when the flange 1 returns to its undeformed flat shape, the flange 1 is held in position against the hand current 11. The flange 1 is thus easy to install and remove for its potential users namely people with reduced mobility, any disabled person with at least one valid arm being able to install or remove the flange 1 of the wheel 7 of Wheelchair .
En faisant coïncider certains des creux A2 , A4, A6 , A8 , A10 et A12 avec les pattes 12 de la main courante 11, et en s 'aidant de l'encoche radiale de saisie 2 pour passer un doigt à travers celle-ci afin de faire traction ou pression sur le flasque 1, le flasque 1 s'emboîte au fur et à mesure des pressions exercées pour finir par passer derrière la main courante 11 afin d'être retenu par celle- ci .  By making some of the recesses A2, A4, A6, A8, A10 and A12 coincide with the tabs 12 of the handrail 11, and using the radial grip notch 2 to pass a finger therethrough to to make traction or pressure on the flange 1, the flange 1 fits as and when pressure exerted to finally pass behind the handrail 11 to be retained by it.
Les ondulations sur le bord externe du flasque 1 permettent la souplesse du flasque 1 et donc la torsion progressive du flasque 1 de patte en patte afin de faire passer le flasque 1 derrière la main courante 11, le flasque 1 flexible retournant dans sa forme plate d'origine à la fin de l'installation.  The corrugations on the outer edge of the flange 1 allow the flexibility of the flange 1 and thus the progressive twist of the flange 1 leg tab to pass the flange 1 behind the handrail 11, the flange 1 flexible returning to its flat form of origin at the end of the installation.
Les ondulations sur le bord externe du flasque 1 lui permettent également de glisser sur les pattes 12 pour, le cas échéant, s ' auto-positionner facilement.  The corrugations on the outer edge of the flange 1 also allow it to slide on the tabs 12 to, if necessary, self-position easily.
Les formes et dimensions des pattes 12 de main courante 11 étant variées, par exemple de forme cylindrique, ovale ou plate, les creux Al à Ail du flasque 1 sont dimensionnés de manière à pouvoir s'adapter à la plupart des pattes 12 de main courante 1.  The shapes and dimensions of the tabs 12 of handrail 11 being varied, for example of cylindrical, oval or flat shape, the troughs Al to Ail of the flange 1 are dimensioned so as to fit most of the tabs 12 of the handrail 1.
Le flasque 1 est retenu exclusivement par la main courante 11 : son bord externe vient en butée contre la face de la main courante 11 en regard de la jante 8. Le diamètre externe du flasque 1 étant supérieur au diamètre interne de la main courante 11, le diamètre du flasque 1 est donc réduit, lors de l'installation, par déformation du flasque 1 par la main 6 de l'utilisateur afin de faire passer le flasque 1 derrière la main courante 11. The flange 1 is retained exclusively by the handrail 11: its outer edge abuts against the face of the handrail 11 opposite the rim 8. The outer diameter of the flange 1 being greater than the internal diameter of the handrail 11, the diameter of the flange 1 is therefore reduced, during installation, by deformation of the flange 1 by the hand 6 of the user to pass the flange 1 behind the handrail 11.
Il est recommandé, lors de l'installation du flasque 1, de placer l'axe radial de l'encoche radiale 2 le plus perpendiculairement possible au sol, le creux A6 situé à l'opposé de l'encoche radiale 2 étant ainsi le premier creux à placer sur le bas de la roue 7 contre la patte 12 la plus proche du sol .  It is recommended, during the installation of the flange 1, to place the radial axis of the radial notch 2 as perpendicularly as possible to the ground, the recess A6 situated opposite the radial notch 2 thus being the first hollow to be placed on the bottom of the wheel 7 against the leg 12 closest to the ground.
Ensuite, grâce aux ondulations formées par les creux Al à A12 et les bosses Bl à B12 sur le bord externe du flasque 1, le flasque 1 s'insère facilement et progressivement au fur et à mesure de pressions de doigts sur le flasque 1 au niveau des bosses Bl à B12 en remontant à droite puis à gauche ou inversement vers le haut du flasque 1.  Then, thanks to the undulations formed by the recesses A1 to A12 and the bumps B1 to B12 on the outer edge of the flange 1, the flange 1 is easily and progressively inserted as finger pressures on the flange 1 at the bumps Bl to B12 going up right then left or vice versa up flange 1.
Le trou central de moyeu 3 est destiné à recevoir le moyeu 10 de la roue 7 de fauteuil roulant, dans le cas où ledit moyeu 10 est dans le plan de la main courante 11.  The central hub hole 3 is intended to receive the hub 10 of the wheelchair wheel 7, in the case where said hub 10 is in the plane of the handrail 11.
Si l'on se réfère à la Figure 6, on peut voir qu'il y est représenté un fauteuil roulant 13 sur lequel est installé le flasque 1.  Referring to Figure 6, it can be seen that there is shown a wheelchair 13 on which is installed the flange 1.
Le fauteuil roulant 13 comprend un cadre 14 sur lequel sont fixés une assise 15, un dossier 16, des accoudoirs 17 et des poignées 18.  The wheelchair 13 comprises a frame 14 on which are fixed a seat 15, a backrest 16, armrests 17 and handles 18.
Le fauteuil roulant 13 possède en outre, fixées au cadre 14, une paire de grandes roues 7 et une paire de petites roues 19, les grandes roues 7 étant identiques à celle représentée à la Figure 4.  The wheelchair 13 further has, fixed to the frame 14, a pair of large wheels 7 and a pair of small wheels 19, the large wheels 7 being identical to that shown in Figure 4.
Le flasque 1 est installé sur l'une des grandes roues 7 du fauteuil roulant 13, chaque patte 12 de main courante 11 étant reçue dans l'un des creux Al à A12 du flasque 1, le bord externe du flasque 1 étant en appui contre le côté de la main courante 11 en regard de la jante 8 de la grande roue 7. The flange 1 is installed on one of the large wheels 7 of the wheelchair 13, each leg 12 of handrail 11 being received in one of the recesses A1 to A12 of the flange 1, the outer edge of the flange 1 being supported against the side of the handrail 11 next to the rim 8 of the ferris wheel 7.
Il est à noter qu'un flasque 1 est de préférence installé sur chaque grande roue 7 du fauteuil roulant 13.  It should be noted that a flange 1 is preferably installed on each large wheel 7 of the wheelchair 13.
Ainsi, une fois installé, le flasque 1 permet de protéger la grande roue 7 du fauteuil roulant 13, et en particulier les rayons 20 de cette grande roue 7, contre les chocs. Le flasque 1 permet également à la personne handicapée installée dans le fauteuil roulant 13 de ne pas se coincer les doigts dans les rayons 20 de grande roue 7 du fauteuil roulant 13 lors de l'utilisation de la main courante 11.  Thus, once installed, the flange 1 protects the large wheel 7 of the wheelchair 13, and in particular the spokes 20 of the large wheel 7, against shocks. The flange 1 also allows the disabled person installed in the wheelchair 13 not to get stuck fingers in the spokes of Ferris wheel 7 wheelchair 13 when using the handrail 11.
Le flasque 1 est de préférence conçu pour une grande roue 7 de vingt-quatre pouces pour fauteuil roulant d'adulte, mais pourrait également être conçu pour une grande roue de vingt-deux pouces pour fauteuil roulant d'enfant ou de tout autre diamètre, sans s'écarter du cadre de la présente invention.  The flange 1 is preferably designed for a 24-inch adult wheelchair large wheel 7, but could also be designed for a twenty-two inch wheel for a child wheelchair or other diameter, without departing from the scope of the present invention.
