Definitions

  • the invention relates to a training device and a wheelchair for the disabled according to the preamble of claim 1 and 13 respectively.
  • a training device should in particular serve to enable intensive training measures for people with paraplegia, paralysis in the leg area and coordination disorders in order to carry out an effective strength training for the paralyzed or disabled muscle groups.
  • a device for independent locomotion of the paralyzed by the muscle strength of their own paralyzed legs which has a frame on which wheels are attached via a front and a rear axle and on which a seat and at least one Footrest are arranged to be movable relative to one another, and which has a force transmission device which converts a relative movement between the seat and the footrest into a driving force and applies this driving force to at least one of the axles by means of a freewheel device.
  • the footrest is attached so that it can be moved back and forth relative to the fixed seat, with e.g.
  • the footrest is moved forward via a muscle stimulation of the legs, and this movement of the footrest is transmitted to the drive device.
  • the footrest is moved back by a return spring arranged on it.
  • a wheelchair is also known according to the preamble of claim 13, in which the seat is pivotally arranged about an axis on the frame, such that a person in the seat can perform a rocking chair-like movement, which in both parts , ie is converted into a driving force during the forward and backward swiveling movement, which lies on the driven axis.
  • this movement is brought about by a shift in the weight of the upper body of the person in the seat without the legs being involved.
  • the object underlying the invention is therefore to create a training device and a wheelchair according to the preamble of claim 1 and claim 13, with which an intensive training of the whole body with mobilization of almost all parts of the body is possible.
  • the disabled person can support his feet on the footrest and by a stretching movement of the legs and by moving the weight of the upper body over the slidably mounted backrest on the other hand move the seat back and forth, during which it moves the entire body during this back and forth movement.
  • a stretching movement of the body is possible in spite of any symptoms of paralysis and leads to therapeutic effects in the physical and psychological area through the active use of the handicapped.
  • the training device according to the invention and the wheelchair according to the invention are thus suitable as rehabilitation training and mobilization devices with a high motivation value, which allow a physically disabled person to perform a harmoniously running full mobilization across all parts of the body with every movement boost.
  • the first exemplary embodiment of the training device according to the invention shown in FIGS. 1 and 2 comprises a frame 3 on which a seat 2 and at least one footrest 1 are arranged so as to be movable relative to one another.
  • the footrest 1 In the foot region of the seat 2, the footrest 1 is fixedly attached to the frame 3, while the seat 2 is held in the longitudinal direction of the frame 3 towards the footrest 1 towards and away from the footrest 1.
  • the seat 2 consists of a backrest 4 and a seat part 5, which can consist of a seat plate with a bucket seat lying thereon and is pivotally connected to the backrest 4 via a pivot axis 10.
  • the seat part 5 is connected at its front section via struts 6 arranged on both sides to a backrest part 7 of the frame 3, the struts 6 being rotatably attached to the seat part 5 and to the backrest part 7 of the frame 3.
  • the back 4 of the seat 2 is slidably held on its back by a roller 9 on the back part 7 of the frame 3, which is attached to the back part 7 so as to be adjustable in the vertical direction.
  • the axis of rotation 10 which connects the seat part 5 and the backrest 4, is guided at its two lateral ends in guide rails 11 which are articulated on the backrest part 7 of the frame and whose angular position, ie whose angle of inclination with respect to the horizontal, is adjustable in order to be adapted to enable the respective person in the seat.
  • a lever 18 is attached to the central part of the axis of rotation 10 and connects to the piston rod of a piston-cylinder arrangement 8 is connected, the cylinder part is rotatably mounted on the frame 3.
  • the piston-cylinder arrangement 8 represents a force absorption device in the form of a two-way piston-cylinder arrangement which is constructed in such a way that both sides in front of and behind the piston in the cylinder are connected to one another via throttles which are adjustable and are connected to a measuring and display device are connected in order to be able to set and read the resistance which the piston-cylinder arrangement opposes to a movement of the piston in the cylinder. In this way, the resistance that the piston-cylinder arrangement 8 opposes to a movement of the seat 2, ie a displacement of the pivot axis 10 in the guide rails 11, can be set.
  • the footrest has a footrest part 13 which is pivotably mounted in the direction of the seat 2 and is provided with an adjustable stop 12 which limits the pivoting movement of the footrest part 13 relative to the seat 2. This adjustment of the amount of pivoting movement of the footrest part enables further adaptation to the respective individual person in the seat.
  • a lever 14 is articulated, which for example consists of two telescopically arranged and mutually adjustable parts, and is connected at its front end via a component 16 to the seat part 5, which can be flexible or rigid.
  • a handle 15 which is connected to means for stimulating the knee joint, which are connected via cables to electrodes which can be attached to the thighs of a person in the seat in order to achieve an extension of the knee joint .
  • the lever 14 is extended beyond the articulation point on the footrest 1, a counterweight 17 or a tension spring being arranged around this extended end To pivot lever handle 15 upwards if it is not pulled down by hand by a person in the seat.
  • the footrest 1 is preferably arranged to be adjustable in the longitudinal direction of the frame, so that an adaptation to the size of the person in the seat together with a corresponding adjustment of the length of the lever 14 is possible.
  • FIGS. 1 and 2 works in the following manner: If a disabled person has taken a seat in the seat 2, and the training device is individually adjusted by the setting options on the lever 14, on the foot part 1 and on the guide rails 11 and the roller 9, then a relative movement between the seat 2 and the footrest 1 can thereby take place that the person possibly stimulated by the stimulation device on the lever 14 extends the legs, whereby the seat 2 is pushed all the way back. This movement takes place against the resistance of the force absorption device 8, which can be adjusted separately for this part of the relative movement between the seat 2 and the footrest 1.
  • the second part of the relative movement i.e. a movement of the seat 2 in the direction of the footrest 1 takes place by a weight shift of the upper body, i.e. by leaning back the person in the seat 2, whereby the backrest 4 slides over the roller 9 and the pivot axis 10 runs forward in the guide rail 11.
  • This part of the movement can be supported by pushing the lever 14.
  • a resistance of the force absorbing device 8 which can be adjusted separately for this movement part, also acts in this movement part.
  • an individual training program can be carried out, in which almost all parts of the body are used, while at the same time stimulating the disabled or paralyzed Muscle areas of the legs can be activated.
  • Such a training device can thus be used in clinics, medical practices and for the home care of patients as a training unit by means of electrostimulation and isometrics, ie training against a metered load resistance.
  • FIGs 3 and 4 a side view of a second embodiment of the training device according to the invention is shown, which differs from the embodiment shown in Figures 1 and 2 essentially in that it is not designed as a purely stationary but also as a movable device, which besides the training option also allows the disabled person to move around and thus represents a kind of wheelchair.
  • the embodiment of the wheelchair according to the invention shown in the drawing consists essentially of a frame R2 to R5 with a front axle and a rear axle, on which wheels A7 and A8 are attached, a seat S1 to S9, which is slidable in the longitudinal direction on the frame R2 to R5 is held, a footrest F1 to F4 in front of the seat S1 to S9, a power transmission device A2 to A6, a steering system L1 to L9, and braking devices, which are not shown in detail.
  • the frame R2 to R5 is formed in two parts and consists of a central tubular frame, the tubes of the two frame parts are pushed into one another and can be locked at the connection point by means of a locking screw R3, so that both a continuous longitudinal adjustment of the Frame as well as a disassembly of the wheelchair in two parts are possible.
  • the seat of the wheelchair essentially consists of a seat part S8 and a backrest S4, which are pivotally connected to one another, the backrest S4 being slidably arranged on its rear side via at least one roller A1, which is attached to a mounting frame R1, which is at the rear end of the frame R2 to R5 is attached.
