Definitions
- the present invention relates to a rollator securing unit of a means of transport, in particular a public transport means such as a bus, train or tram.
- Walkers also called rollators, are walkers for elderly or handicapped people. They enable mobility without outside help and, in particular, they are easy to take along in public transport. Public transport now has satisfactorily functioning fixation and securing means for bicycles and wheelchairs.
- suitable fuses in which the rollator does not have to be folded, but are hardly available.
- WO 2014/177344 Al discloses a device in which the wheels of the rollator are blocked.
- the adjustment of the braking device from a release position to a braking position is preferably carried out by means of an electric motor, which is actuated via a switch.
- This device is relatively complex and expensive and susceptible to interference.
- a securing device for rollators in which a linkage in the form of a parallelogram kinematics is attached to a vehicle wall and can be unfolded as a partition. This allows the walker to park in a newly formed space.
- the folding seat can be pivoted more than 90 °, so that it is on the seat of the rollator to come to rest.
- This device is relatively complicated to use for older people, since on the one hand the partition and on the other hand the folding seat must be operated.
- the folding seat does not provide sufficient security, since it rests obliquely on the seat in most cases.
- sitting on an inclined surface is relatively uncomfortable and for an older passenger mostly not possible because of the movements of the vehicle.
- many rollator models have a back support that makes it impossible to use a folding seat.
- the rollator securing unit according to the invention has a support element, which secures the rollator in its position by resting on a seat surface of a rollator in the case of an external load of the support element from above.
- the support element forms a horizontally extending support surface whose height is variable.
- the support element is height adjustable when used as intended and it forms in different height settings a horizontally extending support surface.
- the Rollatorben Reifener can thus safely seated on this support surface. By sitting on he brings the necessary to secure the rollator external load on the support surface. Since the support surface in a height suitable for the user in the horizontal position can be brought, the user himself can also sit securely and must not laboriously hold his position by force with his legs. J
- the support element is formed only by one or more strips, which are placed on the seat surface of the rollator. The user then sits on the one hand on this at least one strip and on the other hand on the seat of his rollator.

- a first end of a coil spring 68 is attached on the second arm of the pivot lever 670.
- a second end of the coil spring 68 is connected to a rod 69, which preferably extends approximately parallel but spaced from the longitudinal axis of the wound seat mat 64.
- the rod 69 is held at the opposite end in the longitudinal direction in a recess of a receptacle of the housing 60.
- a lock nut 690 is provided. The recess and the receptacle are not shown in the figures.
- One end of the seat mat 64 is fixed to the roller 7. If the seat mat 64 unwound, so that is connected to the roller 7 first gear 654 is rotated. This drives the second gear 654, which rotates about the first bearing 656. This is clearly visible in FIG.
- the second head part 66 also rotates on the opposite side of the Roll 7 with.
- the scroll spring 663 is tensioned. This can be seen in FIG.
- FIGS. 26 to 35 show how the manual withdrawal and the automatic resetting of the seat mat 64 take place.
- the automatic reset preferably takes place only after a time delay.
- the winding movement is braked and slowed down accordingly. This will be explained below.
- the direction of movement of the seat mat 64 is shown in the figures on the left side of the figures, each with thick gray arrows.
- the second gear 655 also rotates and the main body 650 moves along a path A, here referred to as the standard path, relative to the driver 672.
- a path A here referred to as the standard path
- the main body 650 now moves so that the driver 672 comes to lie on the inside of the resilient switch 651.
- the swing arm 670 is pivoted about the pivot axis 671, the fifth gear 676 winds along the sixth gear 676 and the coil spring 68 is tensioned.
- the mechanical timer is thereby charged.
- a secondary track B which is separated from the standard track A by the dividing wall 672, is now used on the main body 650. This is clearly visible in FIG. In FIG. 29, a further rotation of the basic body 650 of almost 360 ° was carried out.
- the driver 672 is now at the first stop 653.
- the coil spring 68 is still stretched maximum.
- the second stop 659 is located at the second end of the slot 657 and thus prevents further rotation of the second gear 655. As a result, the roller 7 can not continue to rotate. The maximum extension position of the seat mat 64 is reached and further extension is prevented thanks to the second stop 659.
- the seat mat 64 is released, i. the externally applied force is removed, so prevents the first stop 653 together with the end face 652 'of the partition 652 a turning back of the main body 650 and thus the roller 7.
- the seat mat 64 remains even without external force in the extended position. This is shown in FIG.
- This embodiment has the advantage that it can be made very compact.
- the inventive Rollator security unit provides easy operation and a secure seat for the passenger and can also train cost and robust.
