Definitions

  • the invention relates to a foldabie wheeled chair principally but not exhaustively developed- for transporting an infirm person or patient.
  • This wheeled chair is intended for propulsion either by the occupant himself or by another person.
  • ' Foldabie wheeled chairs are well-known on the market.
  • German specification 2,150,525 describes a chair with several joints which allow many postures but the chair as described is not foldabie and the different adjustments cannot be achieved by the occupant him ⁇ self.
  • the chair-bed combination described in the US patent 3,053,568 has the short-comings of being heavy, not foldabie and in fact is not a foldabie wheeled chair as usually used by injured or other infirm persons.
  • the wheeled chair described in US patent 3,198,575 is a conventional type of foldabie wheeled chair and is provided with a Joint and a locking device on each side of the chair which permits the chair to be tilted by the occupant himself. But it has the disadvantage that on the one hand the tilting action is very limited and concerns the chair as a unit and on the other hand, necessitates the use of both hands, so that amputees or hemiplegics cannot use such a wheeled chair.
  • Another object of the invention is to provide a foldabie wheeled chair whereby all parts may be separately adjusted.
  • a further object of the invention is to provide a foldabie wheeled chair which may be co ⁇ structed at low cost by providing optional modular and adjustable components.
  • a still further object of the invention is to provide a foldabie wheeled chair which may be used by the greatest possible number of disabied persons and whereby all the adjustments may be effected by the occupant him- - seif.
  • the foldabie wheeled chair of the invention is of the type eomprising a chair mounted on a wheeled frame, said chair having at least a seat, back-rest and foot-supports.
  • the foldabie wheeled chair of the invention is characterized by: 5 - a plurality of modular elements adapted to allow the mounting of the chair on the frame so as to make several modeis of different sizes and uses, said modular elements being located to each other in an adjustable way,
  • control means, the transmission means and the. Joint means are adapted and located, on the one hand, to retain the foldability 0 of the chair without any troubies as is the case in conventional foldabie wheeled chairs, and on the other hand to allow the occupant tp effect all the adjustments to obtain the required position of the chair among an infinity of positions.
  • the foldabie wheeled chair according to the invention is further characterized by foldabie or flexible transmission devices to achieve the 5 transmission of movement from one side to the other of the chair.
  • This particuiar construction allows a symmetrical movement of parts on both sides of the chair, the control means which may be-remote control means being activated by the occupant himself.
  • the control means can be operated by one hand only and may be fixed in the most practical location for him.
  • FIG. 1 is a side elevation of a foldabie wheeled chair embodying the invention
  • FIG. 2 is a front elevation of the same
  • FIG. 3 is a schematic side elevation to illustrate possible relative positions of the chair embodying the invention
  • FIG. 1 is a schematic view of the adjustability of the handle- bar, and of the possible extensions of the chair and wheeled frame.
  • FIGS 5 to 8 are schematic side elevations illustrating different kinds of wheels or castors that may be used with the chair embodying the invention,
  • Figure 9 is a side elevation of a joint means
  • - Figure 10 is a plan of the same joint
  • - Figure 11 is a schematic side elevation to explain the necessity of a compensating device
  • FIG. 12 is a cross section of the foot-support according to the invention and eomprising the automatically compensating device.
  • the foldabie wheeled chair of the invention comprises a wheeled frame 1 and a chair 2.
  • the chair comprises at least a seat 3, back.rest and foot-supports 5.
  • additional components may be added such as arm-rests 6 head-rests (not shown ⁇ leg-rests 7 and a handle-bar 8.
  • the chair 2 comprises a plurality of Joint means as 9 between back-rest 4 and seat 3, 10 between seat 3 and leg-rest 7, 11 between leg-rest 7 and foot-support 5, and 12 between back-rest 4 and handle-bar 8. All these Joint means allow the chair to give an infinity of positions, as each part of the chair can pivot relative to the other part with which it is articulated. These positions will be further explained iater.
  • modular elements 13 On each side of the frame 1 are located modular elements 13 on which wheels 14 or castors 15 of different sizes and types may be mounted. For instance, as shown on figure 5, the front wheel 15 is a castor with a diameter
  • the backwheel 14 has a diameter of about 600 mm and is provided with a well-known hand-rim 16.
  • front wheels 15 are castors of about 200 mm and back wheels 14 are about 300 mm diameter.
  • front wheels 15 have a diameter of about 600 mm and back wheels 14 are 200 mm diameter castors.
  • Figure 8 shows the case where both front 15 and back wheels 14 are about 300 mm diameter.
  • the modular element 13 is adapted to support two adjustable members 17 and 18. These members can for instance slide into the element 13 so as to allow different length of the frame 1.
  • Each member comprises several holes 19, located at the plurality of positions to receive the axles of the different wheels.
  • a telescopic element 20 Located almost on the vertical of the gravity center of the occupant a telescopic element 20 comprises a part 21, fixed to said element 13, and relative to which can slide a second part 22 in a vertically adjustable way.
  • a slide which allows the chair to be folded as it is well-known in the art.
  • the " height of the. Seat may be adjusted by raising. Or lowering part 22 relative to part 21.
  • Locking means such as bolts or other well-known means maintain part 22 in the required position.
  • Part 22 is adapted to support the chair 2 through a joint means 23.
  • the plurality of Joint means allow the chair to give an infinity of positions between a sitting position B-B and a lying or sleeping position F-F.
  • Joint means 23 give the seat 3 an infinity of position between two almost vertical positions G-G and G'-G '.
  • Almost vertical positions means positions as near as possible to vertical positions. In fact these positions depend upon the height where Joint means 23 is raised. The higher it is raised, the more vertical will be these positions. The limitation do not come from Joint means 23 but by the foot-support touching the ground.
  • Position AA is a transferring or stepping in or out position; which " retains the ' chair position BB geatly tilted' f orward to help front transf er, - Position BB is an active sitting-up position. - position CC is a semi-active position,
  • Position E.E. is a resting position.
  • Joint means 9 enables back rest 4 to assume an infinity of positions relative to seat 3 at angles between about 80 ° and 180 °, that is to say between a position a little more closed than sitting position and lying position. When the angle becomes less than 80 the Joint means 9 allows the back-rest 4 to be quickly folded on to seat 3 so as to reduce the volume of the chair when folded.
  • a handle-bar 8 On the rear side of the back-rest 4 is located a handle-bar 8 which may be adjusted in a pivoting way so as to give a plurality of heights as shown by H, I and J on figure 4.
  • the chair is that all the parts are modular, that is they comprise a central part, as for instance 24 in figure 2, relative to which the Joint means (10,11) in this example may be extended or contracted.
  • Each part of the chair may thus be adjusted to the particuiar sizes of the occupant making the chair, in effect, made to measure as shown by positions K, L, tV;, N, 0, P on figure 4.
  • knee joints 25 of the occupant and the Joint means 10 between seat 3 and leg-rests 7 are not coincidental. Knee joints 25 are higher than Joint means 10 and the distance between them depends upon the thickness of the seat 3 and whether or not the occupant uses a cushion. So when the leg is in a horizontal position, the leg rest needs to be longer than when the leg is in a vertical position.
  • the leg tube 24 is provided with an outer tube 26 in which can slide an inner tube 27.
  • This inner tube 27 has the form of a position with a head part 29 which fit the outer tube 26 and a narrower part.30 around which is located a compressio ⁇ spring 31.
  • Spring 31 abuts on one end against the head part 29 of the inner tube 27 and on the other end against the closed extremity 32 of outer tube 26.
  • a locking device such as a screw knqb 33 perrhits the fixlng of inner tube 27 relative to outer ' ; tube 26 in the required position.
  • leg tube 24 is thus in its shortest position, appropriate to the lower leg of the occupant when seated in the normeil seating position.
  • OM-PI occupants legs push the foot-rests thus compressing spring 31.
  • the occupant screws in knob 33, thus fixing the foot-rests in the most suitable position.
  • Joint means are activated by transmission means so as to obtain infinities of positions.
  • said Joint means 10 comprises a driven means 34 fixed to the pivoting part that is the leg tube 24.
  • the driven means 34 cooperates with a driving means 35 fixed to the part relative to which pivots the pivoting part, in this case seat rail 3.
  • Driven means 34 and driving means 35 each eomprising a toothed wheel 36, 37 connected together by a cam-shaft 38 so as to form a well-known pianetary transmission.
  • Transmission means generally are activated by a control means, in this case, a knob 39 fixed to the cam-shaft 38.
  • All transmission means are activated by control means which may be remote control mea s so that they can be located in the most suitable location to enable the occupant himself to obtain the most desirabie position.
  • the control means may be located on either side of the chair. But, due to the fact that the chair is built up from modular elements without any transverse rigidity transmission of desired movement to the other side of the " chair must be achieved by a foldabie or a flexible transmission.
  • Such transmission may comprise cable, universal joint , belt, ... or other well-known flexible or foldabie transmission device.
  • ⁇ r • The description .. s.e_ ... forth illustrates the preferred embodiment of the foldabie wheel chair of the invention. It is to be understood, however, that many variations to the drawings and description may be adopted within the scope of the invention and may never constitute any limitation of said invention.
