Description

CHAISE ROULANTE
La présente invention concerne une chaise roulante, du type de celles pliables en ciseaux, qui est utilisée par des handicapés physiques et pour le transfert des malades dans les hôpitaux, par exemple.WHEELCHAIR
The present invention relates to a wheelchair, of the type which can be folded into scissors, which is used by the physically handicapped and for the transfer of patients to hospitals, for example.

D'une manière générale, les chaises roulantes à usage hospitalier et pour les handicapés physiques, ainsi que les chaises roulantes articulées qui, sans l'usager ou à vide, peuvent être pliées en ciseaux pour permettre une plus grande capacité de stockage et de transport, sont largement connues et sont fabriquées à partir de profilés tubulaires métalliques assemblés par soudage. In general, wheelchairs for hospital use and for the physically handicapped, as well as articulated wheelchairs which, without the user or empty, can be folded in scissors to allow a greater capacity of storage and transport , are widely known and are made from metallic tubular profiles assembled by welding.

De telles chaises roulantes présentent cependant des inconvénients concernant notamment leur fabrication qui nécessite des opérations de soudage, et leur poids qui ne facilite pas leur manipulation tant par les usagers eux-mêmes que par le personnel chargé de les transporter et de les stocker. However, such wheelchairs have drawbacks concerning in particular their manufacture which requires welding operations, and their weight which does not facilitate their handling both by the users themselves and by the personnel responsible for transporting and storing them.

Le but de l'invention est de pallier ces inconvénients tout en procurant d'autres avantages. The object of the invention is to overcome these drawbacks while providing other advantages.

A cet effet, l'invention propose une chaise roulante, du type de celles pliables en ciseaux, comprenant un ensemble de profilés tubulaires, qui est caractérisée en ce que les profilés tubulaires sont assemblés de façon modulaire au moyen d'au moins trois éléments d'assemblage fabriqués en un matériau léger mais résistant tel que du plastique, de l'aluminium ou analogue, à savoir
- deux supports avant et arrière du siège pour assembler sans soudage les profilés tubulaires qui forment la structure de la chaise, et
- une double pièce centrale articulée pour assembler la structure de la chaise sous une forme pliable en ciseaux.To this end, the invention provides a wheelchair, of the type of those foldable in scissors, comprising a set of tubular profiles, which is characterized in that the tubular profiles are assembled in a modular fashion by means of at least three elements d assembly made of a light but resistant material such as plastic, aluminum or the like, namely
- two front and rear seat supports for seamless assembly of the tubular profiles which form the structure of the chair, and
- a double articulated central piece to assemble the structure of the chair in a foldable scissor shape.

Selon un exemple de réalisation de l'invention, le support avant est équipé d'au moins quatre connexions
- une connexion verticale inférieure d'insertion du support de l'axe d'une roue avant, giratoire et complètement libre dans un plan horizontal,
- une connexion horizontale inférieure de fixation du profilé tubulaire formant le longeron inférieur de la chaise,
- une connexion intermédiaire de fixation du profilé tubulaire formant le longeron supérieur de la chaise, et
- une connexion verticale supérieure d'enchâssement et de fixation d'un repose-pieds.According to an exemplary embodiment of the invention, the front support is equipped with at least four connections
- a lower vertical connection for inserting the support of the axle of a front wheel, turning and completely free in a horizontal plane,
- a lower horizontal connection for fixing the tubular profile forming the lower spar of the chair,
an intermediate connection for fixing the tubular profile forming the upper side member of the chair, and
- an upper vertical connection for fitting and fixing a footrest.

Selon encore un exemple de réalisation de l'invention, le support arrière est équipé
- d'un croisillon de passage respectif des longerons inférieur et supérieur, et
- d'un croisillon de support de l'extrémité du longeron de support du siège.According to yet another embodiment of the invention, the rear support is equipped
- a respective passage cross member of the lower and upper beams, and
- a support brace at the end of the seat support beam.

Enfin, selon encore un exemple de réalisation de l'invention, chaque pièce centrale articulée est munie de deux pièces en T de passage des longerons et d'assemblage des tubes de croisillon qui permettent de plier la chaise. Finally, according to yet another exemplary embodiment of the invention, each articulated central part is provided with two T-shaped parts for the passage of the side members and for assembling the cross tubes which make it possible to fold the chair.

Selon le Déposant, il n'existe pas de chaises pliables qui, parmi leurs éléments tubulaires, ont des connexions standards et spéciales ou profilés en matière plastique qui facilitent leur remplacement et qui réduisent le poids général de l'ensemble sans que ceci se fasse aux dépens de sa résistance, tout en augmentant sa facilité de manipulation de la part de l'usager direct, ce qui représente une grande amélioration dans sa fabrication en éliminant les soudures et en permettant un montage modulaire. According to the Applicant, there are no foldable chairs which, among their tubular elements, have standard and special connections or plastic profiles which facilitate their replacement and which reduce the overall weight of the assembly without this being done at expense of its resistance, while increasing its ease of handling on the part of the direct user, which represents a great improvement in its manufacture by eliminating the welds and allowing a modular assembly.

Ces profilés ou pièces d'assemblage en plastique évitent donc la réalisation de soudures sur les profils tubulaires métalliques habituels, ce qui détermine une facilité de construction de la chaise lors du montage et également du remplacement des composants, ainsi qu'une diminution du poids de la chaise, ce qui facilite également son transport et son empilement ou alignement consécutif, ou simplement la manipulation de la chaise de la part de l'usager depuis son lit ou le siège d'un véhicule, etc. These plastic profiles or assembly parts therefore avoid the need for welds on the usual metal tubular profiles, which determines an ease of construction of the chair during assembly and also of the replacement of the components, as well as a reduction in the weight of the chair, which also facilitates its transport and its subsequent stacking or alignment, or simply the manipulation of the chair by the user from his bed or the seat of a vehicle, etc.

Ces pièces d'assemblage avantageusement au nombre de trois sont respectivement, les deux supports du siège, avant et arrière, et les pièces centrales d'articulation en ciseaux de la chaise. These assembly parts, advantageously three in number, are respectively the two seat supports, front and rear, and the central scissor-joint parts of the chair.

Le support avant sert aussi de support et de fixation pour les repose-pieds, et est muni d'au moins deux connexions des tubes supérieur et inférieur, avec un appui supérieur de support de l'extrémité du longeron supportant la tapisserie formant le siège de la chaise. The front support also serves as support and fixing for the footrests, and is provided with at least two connections of the upper and lower tubes, with an upper support for supporting the end of the spar supporting the tapestry forming the seat of the chair.

Le support arrière est muni d'au moins deux connexions pour le passage des longerons inférieur et supérieur précités, et d'un appui supérieur de support de l'extrémité du longeron qui supporte la tapisserie, et sert également de fixation d'une roue arrière et de la pièce de rotation des appui-bras. The rear support is provided with at least two connections for the passage of the aforementioned lower and upper beams, and an upper support for supporting the end of the beam which supports the upholstery, and also serves for fixing a rear wheel. and the armrest rotation part.

Finalement, la troisième pièce est une union tubulaire en T et en plastique qui unit les tubes du croisillon avec le latéral pour permettre le pliage de la chaise. Finally, the third part is a tubular T and plastic union which unites the cross tubes with the lateral one to allow the folding of the chair.
