Definitions

  • the invention relates to a wheelchair, in particular for paraplegic people, which has a frame with a seat, backrest and several wheels, with a lifting device with two bars arranged approximately vertically in use, connected to the wheelchair with deflecting means for deflecting a lifting of the user by hand effecting force into a lifting force which acts on the body of the user via holding means and at least one lifting cable connected thereto, the device being fixable in the raised position of the user.
  • Wheelchair users can often not get up on their own. However, since a temporary getting up both from a medical point of view e.g. is necessary to stimulate the circulation, as well as for practical reasons, e.g. To reach tall shelves or cupboards, various standing wheelchairs have been proposed. A special mechanism is provided in these standing wheelchairs, with which the seat and the backrest can be folded up to a vertical surface and the user is then supported in this position (EP 0 159 562 B1, brochure of LEVO AG, Bleicheweg 5, CH -5605 Dottikon, "The standing aid in a wheelchair”). However, these wheelchairs are relatively heavy and unsightly. With modern light and "active wheelchairs" these wheelchairs are particularly easy to handle, e.g. not comparable when loading into a motor vehicle. A comparable mechanism is proposed on an immovable chair in GB-PS 531,184.
  • the invention is based on the object of providing any wheelchair of the type mentioned at the outset with a stand-up device which allows the imitation of a stand-up movement that is as natural as possible with simple means.
  • the lifting device is designed as a stand-up device which enables the user to stand upright, that at least two deflection rollers are provided as deflection means on each spar, one of which acts on a lifting force acting on the body of the user via a seat belt designed as a holding means force directed upwards, which supports the uprighting movement.
  • the user can, as long as he has sufficient strength and function of the arms, stand up independently and without outside help whenever and wherever he wants. Getting up is facilitated by the fact that the natural uprighting movement is naturally simulated by the force acting on the seat belt, so that the user does not have to internalize any new movements. Complete erection can thus be safely accomplished.
  • the seat belt supports the buttocks and the spars support the upper body.
  • the spars detachable from the wheelchair are pivotally mounted about a pivot point on the wheelchair and can be fixed in a vertical position and the pivot point is preferably arranged between a plane determined by the position of the spars in the use position and the rear wheel below a plane determined by the seat surface
  • the spars can be fixed in the position of use by a quick lock or latching and in the rest position by a quick lock in the area of the pivot point and in a holder and automatically thread into the lower guide sleeve when transferred to the position of use
  • the basically removable spars can also be pivoted out of use on the wheelchair be stored so that it is not necessary to replace the spars from point to point of view every time.
  • the fulcrum for such a pivoting movement is arranged so that the spars can thread themselves automatically, it being irrelevant whether the guide sleeve is now arranged on the spar or stationary on the wheelchair is.
  • the device can be attached and removed in a few simple steps and is easy to operate.
  • the stand-up device is supported forwards via floor supports in use, whereby they are articulated to the spars and can be automatically moved into their supporting position when the spars move into the use position or are formed by the spars themselves.
  • the removable spars are telescopically pushed together when not in use and locked at least in end or intermediate positions. This makes it possible to use the stand-up device for transport and when not in use e.g. in a pocket on the wheelchair. This means that the user has the option at any time to convert his wheelchair into a stand-up device. If the spars are also arranged so that they can be swiveled, all the other components that are not currently required can be stored in a pocket.
  • the knees of the user are held forward by a knee holder against evasion or kinking away, the knee holder preferably being designed as at least one textile band or at least one padded surface, having cutouts for relieving the kneecaps, is padded between the knees and placed around the spars and fixed there. Without this further securing, there is a risk that the knees will dodge to the front when standing up due to the movement of the body or buckle away when standing, which can be safely avoided by arranging the knee holder accordingly.
  • the cutouts also reliably avoid the risk of pressure points (pressure ulcers) on the skin above the kneecaps.
  • the feet of the user are secured on a footplate with at least one securing strap, the adjustable footplate being fastened to the foot part of the wheelchair at the front with hooks or suitable supports and at the rear being attached to the wheelchair with at least one retaining strap that is in the area the heels are widened and hold them sideways.
  • this further optimizes the safety of the entire stand-up device.
  • the seat band is anatomically shaped according to the buttocks and that strips of metal, plastic fibers or similar material are inserted vertically into the seat band and an anatomically shaped plastic part or part of or the entire seat and / or backrest cushion is used as the seat band finds an optimal fit and application security, while the inserted strips allow a safe transfer of forces to the hoist rope.
  • Fig. 2 shows a wheelchair according to Fig. 1, but with the user at the moment of getting up or pulling up.
  • Fig. 3 shows the wheelchair in a further embodiment with pivoted bars.
  • FIG. 1 On wheelchair 13 (Fig. 1), which consists of a frame 13a with a seat 15 and backrest 16 and which is movable via two large wheels 17 and two small wheels 18, which are arranged on the frame 13a, are means for fastening two lateral, in the use position approximately vertically arranged spars 1 attached.
  • a clamping device or something similar can also be used instead for fixing the bars.
  • the spars 1 can be inserted or fastened at any time by the user with a few hand movements, so that he is given the opportunity, wherever and whenever he wants, to transform his wheelchair into a stand-up device which enables the user to stand up.
  • These bars 1 are thus part of a lifting device designed as a stand-up device, which transfers the user's center of gravity to the center of gravity of the wheelchair 13 or at least leads to a relative movement of the two centers of gravity to one another.
  • deflection means for deflecting a lifting force of the user by hand or motor force into a lifting force which acts on the body of the user via a seat belt 7 designed as a holding means and at least one lifting cable 2 connected to it at least two spars 1 can be removed from the wheelchair Deflection rollers 3.4 are provided.
  • a deflecting roller is arranged in such a way that it deflects the lifting force acting on the body of the user into a forward force which is directed upwards and supports the erecting movement. This redirection is essential because this is the only way to effectively support straightening.
  • the seat belt 7 is under the buttocks of the user.
  • the hoist rope either has handles 5 or is driven by an electric motor.
  • the Handles 5 at one end of the rope, while the seat belt 7 is fastened to the opposite end of the lifting rope 2 or to the end of the two rope halves of the lifting rope 2.
  • two hoisting ropes can also be used.
  • the hoisting rope 2 or an equivalent band is secured in at least one fastening device on the spars.
  • This fastening device is designed in the form of clamps 6.
  • rope, sheet or slip clamps can be considered as clamps and, of course, hooks or eyes can also be provided instead of such clamps. After locking the rope, the user can move his hands freely in his upright position.
  • the detachable spars are pivotally mounted on the wheelchair about a pivot point 19, so that the spars do not have to be removed from each point of view.
  • the fulcrum 19 is preferably arranged on an angle plate 25 which is attached below the seat.
  • the fulcrum is preferably arranged in a region which is bounded at the front by the plane of the vertically standing bars and at the top by a plane through the seat surface.
  • the pivot point and spars are connected to one another via a connecting piece 26. Due to the distance gained from the pivot point, it is possible that the spars automatically move during the transfer movement from the rest position into the use position, e.g. thread into the lower guide sleeve 12.
  • the spars 1 are fixed in the area of the backrest on a holder, preferably on a holding fork, and can be secured against unintentional loosening by a quick-release fastener.
  • This quick release can either in Area of the holding fork 23 or, for example, by a rocker arm or a ball lock pin in the area of the fulcrum 19.
  • a quick-release fastener arranged on the connecting piece 26 comes into connection with a detent arranged on the angle plate 25 in such a way that the spars 1 are also secured in this position. This securing can then be released again in the simplest way, for example by a push button.
  • floor supports can be used in both embodiments, which are designated with '20' in the second embodiment. These floor supports have the task of ensuring greater stability to the front when using the stand-up device. If the floor supports are connected to the spars, there is the possibility, in particular in the case of pivotable mounting of the spars 1, that the floor supports can be automatically transferred into their supporting position during the transfer movement of the spars. For this purpose, the floor support 20 and the spars are connected to one another at the front end of the pushed-together spars 1 and the floor supports 20 are also guided in the region of the guide sleeve. However, it is also possible to design the spars 1 so that they also serve as floor supports.
  • the spars can be telescopically pushed together. Furthermore, it is also possible to lock them in full or partial lengths in end or intermediate divisions.
  • a knee holder 8 can be provided which protects the user's knees against evasion or kinking forward.
  • the knee holder 8 is preferably designed as at least one textile band or at least one padded surface, the cutouts in the area of the Has kneecaps and is padded between the knees to avoid the risk of skin injury over the kneecaps.
  • the knee holder 8 is placed around the spars 1 and closed or fixed there in any position, for example by means of a Velcro strip, a clamping plate or a plastic clamp. But it can also be attached directly to the wheelchair.
  • a special foot part or a foot plate is provided, which, however, can also be permanently attached to the wheelchair and in which the user's feet are secured.
  • This foot section is attached to the front of the wheelchair using hooks or a suitable pad or Velcro and is adjustable. At the back, it is hung in the wheelchair with at least one tether 10.
  • the tether 10 is widened in the area of the user's heels and provides support from behind and from the side.
  • the with the handles 5 and the rope 2 • associated seat belt 7 has a buttocks of the user anatomically adapted shape, preferably a buckle that allows a secure hold the buttocks in the seat belt.
  • This curvature can be achieved, for example, by vertically inserted strips of metal, plastic fibers or similar material, which are also suitable for transmitting the forces that occur to the lifting cable 2.
  • the seat belt can be designed as an anatomically shaped plastic part or as part or all of the seat and / or backrest cushions to which the lifting cable is attached indirectly or directly.

Abstract

Un fauteuil roulant peut-être équipé si nécessaire d'un dispositif d'aide au redressement qui comprend deux longerons (1) disposés verticalement pendant leur utilisation, reliés au fauteuil roulant (13) et pourvus de moyens de conversion d'une force manuelle ou mécanique de redressement de l'utilisateur en une force de levage qui s'exerce sur le corps de l'utilisateur par des éléments de retenue et par au moins un câble (2) de levage qui est relié aux éléments de retenue, le dispositif pouvant être fixé dans la position debout de l'utilisateur. Lorsque le dispositif permet à l'utilisateur de se redresser, au moins deux poulies de déviation (3, 4) servent de moyens de conversion sur chaque longeron (1) amovible du fauteuil roulant. Une des poulies de déviation (3, 4) convertit la force de levage qui s'exerce sur le corps de l'utilisateur par l'intermédiaire d'une bande (7) formant siège en une force dirigée en avant et vers le haut qui permet à la personne de se lever plus facilement. On peut ainsi équiper n'importe quel fauteuil roulant d'un dispositif d'aide au redressement qui permet d'imiter par des moyens simples le redressement naturel d'une personne jusqu'à la position debout.
