Definitions

• the invention relates to a rolling device for toddlers.
• Such a rolling device is described in US Pat. No. 1,572,273.
• This rolling device has a wheel-supported shell on which the toddler lies on its stomach.
• lateral beads are provided.
• the toddler can be secured with a belt in the area of the beads.
• the shell tapers at its rear end, so that a rearward-looking extension is formed, on the side of which the child's feet reach past and reach the floor.
• a similar extension is provided on the front of the shell, which tapers towards the front. The toddler can reach past the sides of the front extension with his hands and reaches the floor with his hands. The toddler can move the wheelchair forward by kicking with his legs and grasping with his arms.
• This rolling device can be used for small children from the age of six months.
• this rolling device can only be used to a limited extent for the intended purpose.
• the shell is inclined overall so that a toddler can slide backwards despite the belt. If, on the other hand, the belt is tightened so that slipping is avoided as far as possible, the toddler feels constricted.
• the leg freedom is noticeably hindered by the sharp incisions between the shell and the rear extension. There is also the danger that the toddler can injure himself against objects in the area of the hands when starting off. It is envisaged, for example, to arrange a horse's head on the front part of the front extension, which has the function a bumper takes over; however, this hinders the child's vision and, in addition, the child can at least hurt himself on the horse's head.
• the rolling device consists of a shell shaped according to the body shape of the toddler lying on the stomach and which has a large support surface for the hands following the contours of an oval in the front region, which narrows almost continuously towards the rear into the rear extension.
• the transition area is slightly sloping towards the back and serves as Support surface for the abdominal and chest part of the skin _-..-- i.-ä33 _
• the inclination of the support surface makes it easier to support the hands and control the head movements.
• the legs grasp the rear extension and reach down to the floor, so that the toddler moves forward independently through pedaling movements. Due to the smooth transition between the support surface for the hands and the rear extension, the leg movements of the toddler are not impeded.
• the large contact surface for the hands prevents the child from being injured when bumping into objects.
• the front and side area ⁇ of the large support shell serve as a bumper.
• the wide contact surface for the hands also prevents the child from reaching beyond the side edge and being injured, for example, by rolling the hands over the wheels.
• lateral beads are provided in the transition area between the front support surface for the hands and the rear extension, which prevent the toddler from rolling sideways off the rolling device. These beads can still be guided into the area of the support surface for the hands, so that a lateral reaching out of the toddler over the edge of the shell is reliably prevented in any case.
• the rear end of the rear extension can also be provided with an elevation, which on the one hand slips it reliably prevents toddlers to the rear rc a ⁇ on the other hand also provides good power transmission between the leg movement and the walking device.
• FIG. 1 shows a perspective view of a rolling device according to the invention with the indication of an infant lying on it on its stomach;
• Figure 2 shows a longitudinal section through the rolling device.
• FIG. 3 shows a top view of the rolling device with the indicated position of the wheels
• Fig. 4 is a schematic representation of an embodiment for the front wheels
• Fig. 5 shows a detail from Fig. 4 and
• FIG. 6 shows the schematic representation of a steerable front wheel.
• a rolling device 1 shown in FIG. 1 has a shell 2 which is supported in the front area by two front wheels 3 and in the rear area by a rear wheel 4.
• the shell 2 which is preferably made of plastic, has approximately the shape of a longitudinal section through a pear in the top view according to FIG. 2 and has an approximately horizontal support surface 5 for the hands of the toddler in the front region, which has the contour of a Oval follows, in which case the large axis of the oval runs perpendicular to the central longitudinal axis A of the rolling device.
• the rear end of the shell 2 is formed by a rearward narrow extension 6, the surface of which also extends approximately horizontally. However, the surface of this extension lies deeper than the support surface 5.
• the support surface 5 and the rear extension 6 are connected to one another by a slightly increasing and gradually widening support surface 7, the outer contour of which continuously merges into the oval contour of the support surface 1 .
• an elevation 8 is also provided at the rear end of the rear extension 6, an elevation 8 is also provided.
• the support surface 7 is delimited by upward-facing lateral beads 9, which at least partially extend into the area of the front support surface 5 and the rear extension 6.
• the breast and abdomen area of the toddler is supported by the support surface 7, so that the toddler is relaxed when the hands are supported on the support surface 5.
• the toddler rests with his buttocks on the rear elevation 8, the legs embracing the rear extension 6 so that the toddler is supported on the floor with his feet and can move the rolling device 1 forward by pedaling.
• the shell 2 is concave from below, which results in lateral edges 10, which serve as bumpers 10 ′ in the front and side area of the receiving surface 5 at the same time.
• an inwardly displaced grip bead 11 can be provided essentially parallel to the bumper 10 ', the position of which is designed in this way.
• Det is that even when the toddler grabs this Jr Fulst, his hands are still behind the bumper 10 'so that an injury when starting objects is avoided.
• the support surface 5 is so large that the small child can practically not reach over the edge of the support surface with his hands.
• the front wheels as shown schematically in FIG. 3, are also slightly offset inwards on the underside of the shell, so that any risk of injury is eliminated.
• the overlap is at least partially avoided by the bead 9 extending into the support surface 5.
• the toddler lies on the rolling device in a physiologically favorable position and is secured against slipping and rolling down.
• straps 12 in the area of the beads, which are guided over the back of the child.
• This belt 12 can then e.g. another strap that a parent is holding, e.g. when the rolling device is not used in the home.
• a handle 13 which is only indicated in FIG. 1 and can be inserted, for example, with two prongs into corresponding slots 14 at the rear edge of the elevation 8.
• centrifugal brake 15 can then also be provided for the front wheels, as shown schematically in FIGS. 4 and 5.
• Such centrifugal brakes consist of a plurality of elongated resilient strips 17 mounted on the wheel axle 16, which engage in a recess 18 in the wheel which is coaxial about the wheel axle 16. The recess and the ends of the strips 17 are covered with a friction material. If the rolling device reaches a speed that is too high, the strips are deflected by their centrifugal force with their front ends and pressed against the friction material in the recess. This results in a certain braking.
• Fig. 4 it can also be seen that the front wheels e.g. can be connected to each other with a rigid axle.
• a height adjustment 21 is provided for the rear wheel 4. With this height adjustment, the distance of the bowl from the ground can be changed to accommodate the growth of the toddler.
• the wheel holder has an upwardly pointing screw pin 22 which engages in a screw sleeve 23 fastened in the region of the elevation 8 on the underside of the shell.
• An anti-rotation device can be e.g. with the aid of a splint, not shown here.
• other height adjustments are possible, e.g. with the help of a swiveling single-arm swing arm.
• Such a height adjustment can also be provided for the front wheels 3. However, it has been found that such a height adjustment in the front area of the shell is not absolutely necessary.
• the rolling device is steered by shifting weight, such as this e.g. is known for so-called roller boards for young people.
• a schematic representation of the steerable front wheels is shown in FIG. 6.
• Each front wheel preferably a pair of wheels 3 'in each case, is mounted with its axle 31 in an L-profile 32.
• One leg of the L-profile 32 is rotatably mounted about a bolt 34 which is connected to the underside of the shell of the rolling device in the area of the bearing surface 5.
• rubber pads 35 are attached to the bolt.
• the other leg of the L-profile is designed as a pin and engages in a sleeve 36 on the underside of the bearing surface 5.
• a rubber sleeve 37 is also provided between the sleeve 36 and the leg. In the sleeve 36, the leg can pivot damped by the rubber sleeve 37.
• the rolling device described supports the natural urge of every toddler to get around.
• the toddler understands very quickly how to move forward in a frog-like or alternating manner as soon as it is placed on the rolling device, and observes the objects in its surroundings which are new to it.
• the front widening of the shell allows the hands to be supported and the hands to be handled on the support surface. This strengthens the upper body and the resulting trunk and head control, which is essential for the later straightening of the toddler.
• the motor development of the toddler is physiologically promoted by the operation of the rolling device, the skills gained thereby favor the entire physical, motor and mental development.
• the rolling device can also be used and is beneficial for the therapy of disabled children and for scoliosis prophylaxis.
