Definitions

  • the invention relates to a mobility aid with a first frame member, a second frame member and a footrest, which is arranged between the first frame member and the second frame member, wherein a distance between the first frame member and the second frame member is adjustable to a use distance, wherein the footrest in a use position is brought, and is adjustable to a transport distance, wherein the footrest is brought into a transport position, wherein the mobility aid comprises at least one locking device by which the body contact surface is locked in the use position.
  • Such mobility aids are for example in the form of a wheelchair from US 5,186,480 and in the form of walking aids from DE 296 14 857 U1, the
  • a body contact surface is understood as meaning an area of the mobility aid which, when the mobility aid is used as intended, comes into direct or indirect contact with the body of the user, for example through a cushion or cushion. It is burdened in particular by the user of the mobility assistance.
  • This may for example be a seat, a backrest, for example a backrest or a lower leg rest, or a footrest.
  • These body contact surfaces can be formed as full-surface rigid elements, for example plates, or can merely be a frame element which is covered, for example, with a fabric or cushion.
  • the body contact surface may also be provided with cushioning elements, in particular cushions, in order to increase the comfort of the mobility aid for the user.
  • Mobility aids in the context of the present invention are orthopedic devices for persons with reduced mobility. Mobility aids may be, for example, wheelchairs, walking aids or roilators, or strollers or other mobility-enhancing devices and devices. Such devices and in particular foldable wheelchairs have long been known from the prior art. For example, US 8,419,047 B2 shows a foldable wheelchair. The aim of the corresponding folding mechanism is to be able to reduce the distance between the two frame elements for transporting the wheelchair. In this way, the wheelchair can be stowed to save space for transport.
  • the known from this prior art wheelchair has two footpegs, which are each connected to only one of the frame members. On each of these pegs, the user of the wheelchair can turn off one foot during use.
  • a fabric web is stretched between the two frame elements. Now, if the wheelchair folded, so that the distance between the two frame elements is set to the transport distance and reduced, folds the available to support the lower leg fabric automatically.
  • the two footrests can be folded upwards so that a space-saving position is achieved.
  • Another foldable wheelchair is known for example from US 2015/0245963 A1. Also, this wheelchair can be folded and brought to transport to a smaller pack size and has two separate footpegs, which are arranged on each one of the two frame elements. Again, it is provided that the user of the wheelchair each one of his feet on one of the footrests.
  • a wheelchair which has a footrest, which is arranged between the two compassionelennenten. The footrest is thus connected to both the first frame member and the second frame member. Accordingly, if the wheelchair is to be folded, the footrest must of course also be transferred from a use position in which it is suitable for parking the feet into a transport position. For this purpose, it is similar to the folding mechanism, which is located below the seat of such a wheelchair, folded.
  • the disadvantage is that such a footrest must be loaded from above to contribute to the stability of the wheelchair. This is not possible in particular for persons in whom one or both lower legs have been amputated, so that additional stabilization of the wheelchair can not be achieved, especially for these persons.
  • the folding mechanism in the footrest could also be designed so that it is in the use position in the dead center of the folding mechanism. This means that the position of use is set exactly so that an externally applied to the two frame elements and thus also on the footrest pressure that would otherwise lead to folding the wheelchair, does not lead to movement within the footrest. However, this requires accurate compliance with the lowest possible manufacturing tolerances.
  • the footrest must be moved beyond the dead center in order to fold the wheelchair and bring the footrest from the use position in the transport position. For this reason, the two frame elements would first have to be moved away from each other minimally before folding can take place.
  • the present invention is therefore an object of the invention to develop a mobility aid according to the preamble of claim 1 so that a stability of the foldable mobility aid is increased without the disadvantages known from the prior art occur.
  • the invention solves this problem by a mobility aid according to the preamble of claim 1, which is characterized in that the body contact surface is biased towards the transport position when the body contact surface is in the use position.
  • a locking device can be realized for example by a pin or bolt, which snaps into a recess provided for this purpose or behind a corresponding undercut when reaching the use position.
  • the pin or bolt for example, elastically biased, for example, spring loaded, be.
  • other possibilities of locking which are known in principle from the prior art, can be used.
  • the locking takes place automatically when the body contact surface reaches the use position.
  • a locking device may be present, which must be manually operated, for example, when the body contact surface reaches the use position.
  • the body contact surface is biased towards the transport position when the body contact surface is in the use position.
  • This can for example be done by a mechanical spring element which is compressed when the body contact surface is in the use position. If the lock is released in this case, the bias ensures that the body contact surface is moved from the use position in the direction of the transport position. It is not necessary that it reaches this transport position by the bias, even if this is quite possible and possibly advantageous. It is important, however, that the bias contact the body contact surface can be removed from the use position as soon as the lock that holds the body contact surface in the use position, is released. This is achieved in particular with automatically locking locking devices that the mobility aid is also one-handed operated and collapsible.
  • the body-contacting surface Upon release of the lock caused by the locking device, the body-contacting surface is consequently removed from the use position and moved in the direction of the transport position, so that re-locking in this case is reliably precluded because the body-contacting surface is no longer in the use position ,
  • the body contact surface is lockable in the use position by being loaded in one direction to the use position.
  • a corresponding load for example by feet placed on the body contact surface, is necessary in order to lock the body contact surface in the use position.
  • the locking device is actuated by the load, even if this is possible and possibly advantageous.
  • the body contact surface must be loaded in this direction to ensure that the body contact surface actually reaches the use position.
  • the body contact surface does not reach this use position if necessary, which is changed by a corresponding load in the direction of the position of use. As a result, the body contact surface reaches the use position and an automatic latching or locking locking device is actuated.
  • the mobility aid has a Lös adopted, by which a locking of the body contact surface in the position of use is solvable.
  • This can be achieved, for example, by an actuating element, by means of which a locking element snapped into a recess or behind an undercut is removed from this latched position.
  • an actuating element by means of which a locking element snapped into a recess or behind an undercut is removed from this latched position.

Thus, the position of the steering wheel and thus the height of the body contact surface above the ground can be individually adjusted very fine without a constructively large effort would have to be operated.
