    The invention relates to an axle which is attached to two of the front sides of the rollator, on which locking levers sit, which are folded onto the swivel wheels of the rollator with a switching lever in order to hold them in place. Strong additional wheels are attached to the gear lever, which help to overcome descents with large descents.

    专利说明:

    There are many old or handicapped people today who use a walking aid, a so-called rollator (Fig. 1). The mostly 2 rigid rear wheels (Fig, 1a) and 1 or 2 swiveling front wheels (Fig.1b) has. It has now been shown that when getting off and off the bus, train, tram or sidewalk (these differences in height are referred to in the application as descents), i.e. when descending, the swiveling front wheels tend to move sideways at a high step. And thus cause a not inconsiderable uncertainty, especially in older people, and the holding times of e.g. Extending buses unnecessarily.
    Therefore (Fig.3) was invented, where we move via (Fig.3e) shift lever, the (Fig.3g) washers, the (Fig.3d) washers with the welded over the (Fig.3a) shift rod Turn the axis on which the (Fig.3c) locking levers sit, which when folded down onto the (Fig.3f) wheels prevent them from pivoting.
    (Fig. 5) Descent
    Likewise, (Fig.5) was invented.Where we move the (Fig.5g) washers with the (Fig.5e) shift lever over the (Fig.5a) shift rod the (Fig.5d) washers with the welded axis on which the (Fig. 5a additional wheel holder with the (Fig. 5) rigid additional wheels are mounted. If we fold them to the floor, the (Figlb) swiveling wheels are inoperative, which means that we can climb even larger descents or even further distances Be able to overcome the ramp.
    (Fig. 6)
    With (Fig.6) we have an additional effect that helps us when getting on the bus and when overcoming higher ramps ectr. Here we switch with the (Fig. 6e) shift lever (Fig. 6d) the rondelle, the movement with the (Fig. 6a) shift rod, to (Fig. 6b) the rondelle with the welded axle which in turn transfers the (Fig. 6b) starts turning and so (Fig.6a) the additional wheel holder and the attached (Fig.6) additional wheels can be lowered onto the bus floor (or onto another obstacle). With the (Fig. 6e) switch lever we lift the rollator up and only have to rewrite it.
    Title1)
    At the front of the rollator (Fig.1) an axis (Fig.3b) is built on the right 2 and left 2 locking levers (Fig.3c), which we from behind (handle side) with the switch rod (Fig. 3a) can fold onto the swivel wheels, making them rigid.
    See (Fig. 3)
    Title 2)
    On the locking lever (Fig.3c) we can each mount a rigid additional wheel (Fig.5) through (Fig.5a) Zusatzradhalterungjeein, which, when folded down by the shift lever (Fig.5e), extends the distance to the rigid rear wheels, which causes that we can overcome even larger descents - or even further distances to the ramp.
    Title3)
    The rigid wheels (Fig.6) mounted on the additional wheel holder (Fig.6a) also help us when getting on the bus, train or over high ramps and sidewalks as (Fig.6) shows, e.g. when we have shopped heavily.

    State of the art!
    In order to help people with walking disabilities to participate in daily life, the so-called rollator was created. (Fig. 1)
    Most models have 3 to 4 wheels. Whereby 2 (Fig.1a) are rigid. The rest are so-called swivel wheels so that the device can be controlled. It has now been shown that on larger descents the swivel wheels are positioned transversely See what unnecessarily hinders the processes.
    Another problem is that the bus drivers usually do not drive too close to the ramp or, above all, there are no ramps in the country.
    Another problem is getting into the bus because the rollator, which has a lot of weight, especially after shopping, has to be raised to get into the bus / sidewalks / ramps.
    Presentation of the invention!
    Title 1.)
    In (Fig.1) a standard rollator with 2 rigid (Fig1a) and 2 swivel wheels (Fig.1b) is shown for better understanding as it is used today by the disabled, especially older people. They usually also use public transport. Now there is a difficulty. Because the swiveling wheels of the rollator tend to stand sideways when the descent exceeds a certain height, which above all unsettles anxious people and unnecessarily increases the stopping times of the buses, or discourages unsettled people from using the bus at all.
    The invention solves the problem in which an axis on the front frame of the rollatorA pair of locking levers (Fig.3c /) sit on the handle side of the rollator by means of a switch lever (Fig.3e) and thus prevent the swiveling wheels from pivoting. As soon as the rollator has reached the floor, we can open the locking lever again with the same switch rod and the wheels can be swiveled again. See (Fig. 3)
    Presentation of the invention
    Title! 2)
    On the locking lever (Fig.3c) we mount with (Fig.5a) additional wheel holder rigid (Fig.5) additional wheels which we fold down with (Fig.5e) shift lever, and so the distance to the rigid (Fig.1b ) Increase the size of the rear wheels and thus be able to negotiate higher descents and longer distances to the ramp.
    Presentation of the invention!
    Title 3.
    (Fig.6) Further possibilities of the additional wheel shows as here with the help of the (Fig.6) additional wheel, which we press with the (Fig.6c) shift lever on the (for example on the bus floor, and so also lift the rollator with the loaded rollator can effortlessly climb higher steps on buses, trams, trains, sidewalks or ramps.

    Execution of the invention!
    The length of the axis (Fig.3b) is determined by the distance between the swivel wheels (Fig.1b), it must be so long that the locking lever (Fig3c) sit firmly on it and when folded down exactly towards the swivel wheels come sit. Therefore the lower 40mm are slightly spread outwards so that you can still straighten the wheels. They should be about 160 mm long (depending on the diameter of the swivel wheel) screws without head M10x160mm which we insert into the pre-drilled holes in the axis
    Before attaching the locking lever, we push the bearing bushes (Fig3h) with the welded tabs (Fig3i) with which they are attached to the front tube of the rollator on the axis.Rondelle (Fig.3d) is to the right or left of the axis ( Fig.3b) Welded on (left or right-handed) Rondelle (Fig.3g) is attached to the rollator with clamps on the same side. The two rondelles with a diameter of about 150 mm are connected with the shift rod (Fig.3a) so that the movement of the shift lever (Fig.3e), which is welded to the rondelle (Fig.3g), is on the axis (Fig3b) transfers and we can lower the locking lever (Fig3c) on the wheels.

    Title 2 and 3!
    Descent from the bus and boarding (Fig. 5/6/7)!
    In the additional wheel holder (Fig.5a / 6a / 7a) the length depends on the diameter of the additional wheel and the swivel wheel, there are two flat iron dimensions 30x5mm and are welded or screwed on one side between the locking lever. Then we mount the additional wheels on the other side between these two flat iron (Fig. 7) the length of the flat iron should be such that the two wheels (swivel + rigid additional wheel do not touch each other

    Claims (3)
    [1]
    1. An axle (Fig.3b) which is attached to the rollator on the front side on which a pair of locking levers (Fig.3c) sit on the left and right,A gearshift lever (Fig.3e) characterized in that we fold the locking lever (Fig.3c) onto the wheels via the gearshift rod (Fig.3a) (and can thus make them rigid) and with the same gearshift lever (Fig.3e) be folded up again after the descent is complete
    [2]
    2. Additional wheels (Fig. 5) which are attached to the additional wheel holders (Fig. 5a)This is characterized by the fact that we can fold the additional wheels with the gear lever (Fig. 5e) on the floor and thereby extend the distance to the rigid rear wheels (Fig. 1a), with which we can overcome even higher descents or distances to the ramp. Afterwards, the additional wheels are folded up again with the gear lever.
    [3]
    3. Additional wheels (Fig. 6) which are attached to the additional wheel holders (Fig. 6a)Characterized by this (if we have bought something difficult) and when getting on the bus or overcoming a higher ramp - the lifting of the rollator exceeds our strength. We push the rigid wheels (Fig. 6) onto the obstacle (e.g. bus floor, ramp) with the gear lever (Fig. 6e) until we have raised the rollator so much that the swivel wheels (Fig. 1b) effortlessly onto the bus floor or ramp on and we practically only have to push the rollator in.
