Definitions

  • the present invention provides a chair for handicapped or elderly persons walking with difficulty, as set out in claim 1.
  • a rollable supporting device to be pushed by the handicapped person must be very stable and this is also true for a transporting chair for indoor use.
  • the downwardly directed forces should most likely intersect the ground or floor surface inside the polygon defined by the position of the wheels or rollers.
  • the vertical projection of the hand grips falls inside the polygon defined by the wheels and is spaced substantially from the sides of the polygon in said first position of the releasably mounted wheel or wheels, while the vertical projection of the hand grips falls outside said polygon or closely adjacent to a side thereof in the second position.
  • the chair seat may then be pivotally mounted to one of the frame parts so as to be rotatable between a substantially horizontal position of use and an upright storing position, and if desired the chair seat or a pivotally mounted frame part supporting the seat may be shaped so as to form part of the releasable locking means.
  • the chair seat In its unstressed condition the chair seat may define a substantially plane upper surface and may then serve as a tray on which a handicapped person using the chair as a leaning or supporting device may place various objects or items.
  • the chair shown in Figs. 1-3 comprises a chair frame 10 which may be made from metal tubes, a chair seat 11 and a chair back 12 mounted on the frame 10.
  • the frame 10 comprises a front frame part 13 forming a pair of front legs 14 and a rear frame part 15 forming a pair of rear legs 16.
  • a pair of rear wheels or rear rollers 17 are rotatably mounted at the lower ends of the rear legs 16, and a pair of caster wheels 18 are mounted at the lower ends of the front legs 14.
  • a pair of rearwardly directed hand grips 19 positioned behind the chair seat 11 are formed at the upper ends of the rear frame part 15.
  • Braking devices (not shown) for selectively braking the rear wheels 17 may be selectively operated by means of brake actuating members 20 which are positioned immediately below the hand grips 19 and which are connected to the braking devices via cables 21.
  • the frame parts 13 and 15 are interconnected by link members 22 so that the frame parts 13 and 15 may be moved between a collapsed position shown in Fig. 3 and a position of use shown in Figs. 1 and 2. In the position of use the front legs 14 and the rear legs 16 are spaced apart and may be locked in this position by a link member.
  • the chair seat 11 may be pivotally mounted to the rear frame part 15 at its rear edge so that the seat may be tilted between a substantially vertical position and a substantially horizontal position of use, and the link members may also comprise a frame part for supporting the chair seat 11 in its substantially horizontal position of use.
  • An upwardly open container or basket 23 which may, for example, be made from wire, is mounted under the chair seat 11, vide Figs. 2 and 3, so that the chair seat 11 may form a lid closing the upper open end of the container or basket 23.
  • the container or basket 23 may be mounted so that it may be displaced transversely in relation to the seat 11 whereby a person sitting on the chair seat 11 may gain access to the inner space of the basket or container.
  • Fig. 4 illustrates how the chair shown in Figs. 1-3 may be used as a supporting or leaning device (a so-called rollator) by a handicapped person who needs a walking aid. The person then grips around the hand grips 19 and pushes the chair in front of him. When necessary, the user may operate the brakes by means of the brake actuating members 20.
  • the chair bag 12 may be mounted pivotally about a horizontal axis so that the chair back may be moved between a substantially vertical position as shown in Fig. 1 and a substantially horizontal or an inclined position. As shown in Fig. 5 the user of the chair may then lean against and partly sit on the substantially horizontal or inclined chair back 12 so as to get a small rest in an upright, almost standing position.
  • the chair may also be used for transporting a handicapped person sitting on the chair seat 11 and leaning against the substantially vertical chair back 12. An assisting person may then grip the hand grips 19 and push the chair.
  • the chair shown in Figs. 1-3 is preferably provided with a foot rest 24 (shown only in Fig. 6) for supporting the feet of the sitting person so that the feet do not come into contact with the floor or ground surface during transportation.
  • the chair may also be used as a chair for a person sitting at a table or at a similar working place. In that case the braking devices should be operated so that the chair does not move.
  • Figs. 8 and 9 illustrate an embodiment similar to that shown in Figs. 1-3, and similar parts are provided with the same reference numerals.
  • the rearwardly inclining rear legs 16 are provided with three different wheel mounting bores or openings 25, 26 and 27 positioned in different levels and in different transverse positions in relation to the hand grips 19.
  • the small diameter rear wheels 17 may then be replaced by large diameter rear wheels 28 which may be gripped and moved by a user sitting in the chair. Thereby the chair may be converted into a wheel chair which is also suited for outdoor use.
  • a person gripping the hand grips 19 and pushing the chair forwards usually applies a downwardly and forwardly directed force F to each of the hand grips 19.
  • the small diameter rear wheels 17 are mounted on the chair such force intersects the floor or ground surface between the contact points 29 and 30 between the floor or ground surface and the front and rear wheels 18 and 17, respectively.
  • the large diameter rear wheels 28 are mounted the downwardly directed forces F may intersect the ground surface adjacent to the contact point 31 between the rear wheels and the ground surface. This means that a person gripping the hand grips 19 and pushing the wheel chair may rather easily tilt the chair about and axis defined by the contact points 31 whereby the front wheels 18 may be lifted for passing small elevations in the ground surface, such as kerbs, doorsteps and other hindrances.
  • the front frame part 13 and the rear frame part 15 are mounted so as to be mutually pivotable about a pivot 37.
  • a pin or cam follower 38 formed on each of the rear legs 16 is cooperating with a corresponding slot or track 39.
  • the pins 38 may be releasably locked in alternative positions in which they are engaging with the opposite ends of the slots 39 whereby the chair may be converted from the position shown in Fig. 13 in which it is adapted to be pushed by the handicapped person, into the position shown in Fig. 14, in which the handicapped person may sit in the chair and be pushed by an assisting person.
  • Figs. 15 and 16 show an embodiment in which the chair back 12 may be swung from a position shown in Fig. 15 in which it is in abutting engagement with the seat 11, into a position of use shown in Fig. 16. Furthermore, each rear leg 16 comprises telescopically moveable parts which may be mutually locked in predetermined positions so that the height of the mounting bore 25 for receiving the shaft or pivot of the corresponding rear wheel 17 may be adapted to the diameter of the rear wheel chosen.
  • Figs. 17 and 18 corresponds to the embodiment shown in Figs. 15 and 16.
  • the chair seat 11 and the chair back 12 are formed as an integral unit which is tiltably mounted on the chair frame 10 about a pivot axis 40.
  • the chair is used for transporting a handicapped person in a sitting position, the seat and back is tilted to the position shown in Fig. 17.
  • the chair is to be pushed by the handicapped person the seat and back may be tilted to the position shown in Fig. 18.
