  • wheelchairs to be propelled by a seated user come in two basic types.
  • the first and most established type of wheelchair provides a seat with a seat back and armrests.
  • the seat sits on a frame, to which a pair of large diameter rear wheels are attached so as to support the scat.
  • a pair of front swivel or castor wheels is mounted to a front of the frame to support a front of the seat and it is noted that sometimes the seat armrests are integrally formed with ihe wheelchair frame.
  • the front swi el wheels provide significant mobility for the wheelchair in tight
  • a three-wheeled wheelchair has been developed.
  • the three- wheeled wheelchairs are similar to the wheelchair of the first type above but instead of providing a pair of front swivel or castor wheels a single castor wheel extends from the front: of the chair a predetermined distance to provide a substantially increased wheelbase.
  • the three-wheeled wheelchair has been designed to provide sturdiriess and practicality over fine chair control and are used almost exclusively for sporting activities, particularly racing.
  • the three-wheeled wheelchairs are designed to maximise the "pushing" efficiency of the user and have seating surfaces and frames configured to achieve this.
  • the front castor wheel includes a steering mechanism akin to bicycle handle bars so that the user can steer the wheelchair with differential force applied to the rear wheels or by leaning forward and applying force to the steering wheel.

  • the diameter of the front wheel is larger than that of a conventional castor or swivel wheel.
  • the increase in wheelbase length allows significantly better tracking and stability for use of the wheelchairs on uneven terrain and the large front wheel allows greater undulations to be climbed such as curbing and guttering.
  • the increased wheelbase length and use of a laTger diameter wheel also allows a user to expend less energy to cover greater distances than is the case with the first type of conventional wheelchair above. .
  • Use of the three-wheeled types of wheelchairs allows users to have access and freedom to outdoor and other areas not previously or practically accessible in four- wheeled wheelchairs.
  • use of the three-wheeled wheelchairs requires the user to swap from the first type of conventional wheelchair to the three-wheeled type of wheelchair when going from inside to outside and vice- versa when going from outside to inside.
  • the most significant disadvantage associated with this is that many wheelchair users cannot easily transfer bet ween wheelchairs withoul the aid of lifting equipment, assistance from a carer or the application of significant effort from the . user of the chair. This limits the usefulness of providing the two types of wheelchairs.

Abstract

Cette invention concerne un mécanisme pour fauteuil roulant (15) s'étendant entre une extrémité du support d'assise (16) et une extrémité du support de roue de chariot (17). Le mécanisme pour fauteuil roulant (15) est conçu pour supporter une partie avant (9) d'assise (2) de fauteuil roulant à l'extrémité du support d'assise (16) et une roue de chariot (18) à l'extrémité du support de roue (17). Le mécanisme pour fauteuil roulant (15) est conçu pour se déplacer d'une première position où la roue de chariot (18) s'étend sur une distance prédéterminée à partir de l'assise du fauteuil (16) et supporte la partie avant d'assise du fauteuil roulant et une seconde position où la roue de chariot (18)se trouve plus haut qu'une paire de roulettes (10) qui supportent la partie avant de l'assise. Cette invention concerne également un mécanisme de restriction de roue pivotante pour commander le pivotement d'une roue pivotante avant d'un fauteuil roulant à trois roues et un mécanisme d'alignement (40) de roue pivotante de fauteuil roulant. Le mécanisme d'alignement (40) comporte une plaque d'alignement (20) montée entre un support de roue pivotante et une roue pivotante, ledit plateau d'alignement étant conçu pour tourner entre une position gauche où la roue pivotante tourne d'un angle prédéterminé dans une direction gauche et une position droite où la roue pivotante tourne d'un angle prédéterminé dans une direction droite.
