Definitions

  • the present invention relates to a rollator or a wheelchair for handicapped persons.
  • Rollators and wheelchairs are well known in the art. Such rollators or wheelchairs are considered small cars formed having four wheels, wherein the front wheels, so aligned in the direction of travel wheels are rotatably mounted about a vertical axis. These wheels are used to steer the rollator or wheelchair. Furthermore, the problem is described using the example of the rollator; this applies equally to a wheelchair. At the rear end are two handles on which the person can support one hand and on the other pushes the rollator. The rollator itself can also have a seat and a small take-up for carry-on luggage. In addition, such rollators are often provided with a brake. For transport and storage, such walkers can also be collapsible.
  • rollators are already known from the prior art, which should help in overcoming heels and small steps. So is out of the WO 2005/107678 A2 a walker known which has a climbing aid in the front wheels between the front wheels.
  • the climbing aid comprises a ledge which has been bent forwards and which is connected to the frame of the rollator by a closed four-bar linkage.
  • T2 From the DE 602 11 439 T2 is another climbing aid for rollators known in which between the two front wheels, a device is provided, which pivots when creating an obstacle between the wheels and thereby practically up the rollator. When jacked up, the handbrake should then be tightened in order to lower the front wheels of the rollator on the obstacle. The problem is that in this case the rollator tilts itself backwards, which affects the balance of the handicapped person. It should also be noted that this only obstacles can be overcome, which are actually over the entire width of the rollator before the rollator. Stones and bumps, which are only in the way of the one wheel, can not be overcome hereby. Another embodiment of a climbing aid from this reference is not suitable to facilitate a handicapped person using such a rollator overcoming obstacles. In the embodiment according to FIG. 3 must be overcome to overcome the obstacle not inconsiderable frictional forces, which is not easy for these people. In addition, here too the rollator at the moment of Pivoted upward, which adversely affects the equilibrium of the handicapped person.
  • the invention is therefore based on the object to provide a walker or a wheelchair for people with mobility problems, with essentially no additional effort and, in particular for a walker, without the balance of the disabled person on the rollator is significantly impaired, at least low obstacles in the area from 1.5 to 6 cm can be overcome.
  • the two wheels are connected to each other by a belt or chain drive, preferably a belt drive is used.
  • a belt drive is used.
  • the belt or chain drive is at least moved by the rear, so the larger wheel of the two wheels.
  • the chain or belt drive thus serves as an active climbing aid on the obstacle; any frictional forces do not need to be overcome. Otherwise, the pair of wheels will rise through the belt or chain drive; this ensures the climbing up. That is, by the belt or chain drive, the movement of the front wheel is transmitted to the rear wheel and vice versa, so that the belt or chain drive overcomes the distance between the front and rear wheels without the occurrence of friction forces on ascent. It is essential that no frictional forces arise, which require a greater effort in the rise of both the front smaller wheel and the rear larger wheel.
  • the holder has a stop, wherein on the rocker means, for. B. a screw is provided, which cooperates with the stop.
  • the distance between the front wheel and the ground is adjustable. This is done with the help of the screw and the stop. Because As a result, the angular position of the rocker and thus the distance to the front wheel can be changed to the ground.
  • the wheels have a circumferential groove for the belt or chain drive, wherein the belt advantageously rests in the groove of the wheels so that the belt protrudes beyond the lateral surface of the wheel, which ultimately means that the wheel runs on the belt.
  • the wear of the belt is still limited, since belts, for example in the form of V-belts, are extremely stable.
  • the rocker is designed as a double rocker with two rocker blades, wherein the wheels are rotatably mounted between the two rocker blades. This results in an increased stability of the device as a whole.
  • the generally designated 1 rollator comprises the frame 2, wherein the frame 2 has a rear pair of wheels 3 and two front wheel devices 4, which are connected by a cross member 5.
  • the frame 1 also has a braking device 7, which acts on the rear pair of wheels 3.
  • the invention relates to the wheel device 4, as in FIG. 3 is shown.
  • the frame 2 receives the holder 10, wherein the holder 10 is rotatably mounted about a vertical axis 11 on the frame of the rollator.
  • the holder 10 includes a double rocker 12, wherein the double rocker 12 composed of two mutually parallel rocker blades 12a, between which the two wheels 15 and 16 are rotatably mounted on the double rocker.
  • the double rocker 12 is connected to the U-shaped holder 10 about the swing axis 12b.
  • the two wheels 15, 16 have on their outer circumferential periphery a groove 19, 20, in which the belt 25 is guided.
  • the belt drive is advantageous about the peripheral surface of the wheel, so that the belt drive has always ground contact both in the front and in the rear wheel 15, 16.
  • the front wheel 16 is able to pivot upward in the direction of the arrow 35 due to the pivotable arrangement of the rocker 12 on the holder. That is, overcoming obstacles is possible even if the distance is not set exactly to the height of the expected obstacle. In this case as well, if such a slightly higher obstacle is to be overcome, the occurrence of frictional forces is avoided in any case, since the belt drive 25 always participates in the forward movement.
