Title
(EN) WHEELCHAIR WITH TWO INDEPENDENT DRIVING ARMS
(FR) FAUTEUIL ROULANT COMPRENANT DEUX BRAS D'ENTRAÎNEMENT INDÉPENDANTS
Abstract
(EN)
Wheelchair (10) with two independent driving arms (21, 21'), comprising a seat (16), two rear large wheels (12, 13) and two front small wheels (14), wherein the small wheels (14) can be freely turned around a vertical axis, and a common frame (11) for holding the listed parts, and the two driving arms (21, 21') are fixed to the frame (11) by means of respective pivot bearings (25) which are fixed at a low position close to the place where the small wheels (14) are attached to the frame (11), and the driving arms (21, 21') extend till a height which is sufficiently high for the person sitting in the wheelchair (10) to hold their upper end portions easily with hands and to move them in forward-backward directions around the respective pivotal bearings, and both of the large wheels (12, 13) are equipped with respective brakes that can be operated by the driving arms (21, 21') or by respective brake handles (42) positioned on the driving arms (21, 21'), and to respective lower sections of the driving arms (21, 21') respective ropes (32, 32') are connected, and the two large wheels (12, 13) comprise respective wheel hubs (30, 30') each equipped with freewheel, and to one side of each wheel hub (30, 30') a respective one of rope drums (31, 31') is attached, the rope drums (31, 31') are each provided with a spring bias, and a winding made of said rope (32, 32') comprising a predetermined number of turns is provided on the mantle of each rope drum (31, 31'), wherein a predetermined displacement length of the pulling of the rope (32, 32') in forward direction results in a given turning of the associated wheel hub (30, 30') in forward direction, and when the rope drum (31, 31') is turned in the other direction the freewheel releases the connection towards the large wheel (12 or 13), and the wheel hub (30, 30') comprises a release mechanism that releases the locking of the freewheel when the large wheel (12 or 13) is moved in backward direction and backward movement gets allowed.
(FR)
La présente invention concerne un fauteuil roulant (10) comprenant deux bras d'entraînement indépendants (21, 21'), comprenant une assise (16), deux grandes roues arrière (12, 13) et deux petites roues avant (14), les petites roues (14) pouvant être tournées librement autour d'un axe vertical, et un cadre commun (11) pour supporter les pièces indiquées, et les deux bras d'entraînement (21, 21') étant fixés au cadre (11) au moyen de paliers pivotants respectifs (25) qui sont fixés à un emplacement bas proche de l'endroit où les petites roues (14) sont fixées au cadre (11), et les bras d'entraînement (21, 21') s'étendant jusqu'à une hauteur qui est suffisamment élevée pour que la personne assise dans le fauteuil roulant (10) tienne facilement ses parties d'extrémité supérieures avec ses mains et les déplace dans les directions avant-arrière autour des paliers pivotants respectifs. Les deux grandes roues (12, 13) sont équipées de freins respectifs pouvant être actionnés par les bras d'entraînement (21, 21') ou par des poignées de frein respectives (42) positionnées sur les bras d'entraînement (21, 21') et des câbles respectifs (32, 32') sont reliés aux sections plus basses respectives des bras d'entraînement (21, 21'), et les deux grandes roues (12, 13) comprennent des moyeux de roue respectifs (30, 30'), chacun équipé de roue libre, et chaque tambour de câble (31, 31') est fixé à un côté de chaque moyeu de roue (30, 30'), les tambours de câble (31, 31') sont munis chacun d'une sollicitation à ressort, et un enroulement constitué dudit câble (32, 32') comprenant un nombre prédéfini de tours est placé sur la gaine de chaque tambour de câble (31, 31'). Une longueur de déplacement prédéfinie du tirage du câble (32, 32') dans la direction avant provoque une révolution donnée du moyeu de roue associé (30, 30') dans la direction avant, et quand le tambour de câble (31, 31') est tourné dans l'autre direction, la roue libre libère la liaison en direction de la grande roue (12 ou 13), et le moyeu de roue (30, 30') comprend un mécanisme de libération qui libère le verrouillage de la roue libre quand la grande roue (12 ou 13) est déplacée dans la direction arrière et le mouvement vers l'arrière devient permis.
