"Children's fairground bike ¹¹

The innovation concerns a child's vehicle wheel, in particular ~ Special roller wheel, which is designed as a spoked wheel and on which tires can be pulled.

As far as it is known so far to use spoked wheels as roller wheels, which are made of rims, wire spokes and ball bearing hubs are assembled to form a wheel, require such cages due to their many individual parts tedious manual labor. The spokes can easily loosen and thus damage the soap or the The shape of the rim base can be changed disadvantageously.

The task of the innovation is to create a children's vehicle wheel that is largely machine-made can and the disadvantages of previously known children's bicycles avoids.

According to the innovation, a children's vehicle bike, in particular scooter wheel, whose rim base with outer flanged edges for pulling an air or Solid rubber tire is equipped, this rim base is constructed in several parts, with its parts each merge into the openwork discs of Hades, which accommodate the bearings. In an expedient embodiment such a rim well has a central profile ring around which the edge strips the wheel disks.

Such a child's vehicle wheel can be manufactured using an assembly line process without substantial manual labor will.

In the drawing is an embodiment of the firing shown.

Show it:

Mg. 2 a section through the same Sad according to section line I-I in Jig. 1.

For example, by embossing from a metal strip Manufactured rim base is rounded in a circle and welded seamlessly at its ends. It shows an im Cross-section symmetrical design and an axially aligned rim base 10a. Stand on either side of this curved rim walls 10b, 10c to the outside, which at a certain distance to the outside in opposite Arched direction and bent in the opposite direction to approximately radially extending ends.

On the outside of the rim walls 10b, 10c, disks Ha, Ha 'with corresponding gradations are applied. These are with their outer marginal strips Hb, 11b * around the free Ends of the rim walls 10b, 10c flanged into it. The beaded end of the panes nestles against it

11a, 11a 'closely to the protruding ends of the rim walls 10b, 10c and, like these, extends radially Direction, so that there is a risk of damage to a rubber tire or the like. and a risk of injury during assembly by protruding G-rate avoided will. The rim base 10a, the rim walls 10b, 10c, which form a profile ring, and the flanged hand strips 11b, 11b 'of the disks form a stepped or bent multi-part rim base that holds the mounted tire.

Such disks 11a, 11a ^! of a roller wheel, in which the edge strips 11b, 11b ¹ the spokes lic, 1lc ^f and the flange plates Hd, 1ld ^! are punched in, receive their final shape in a subsequent embossing process.

These disks 11a, 11a ^! on the other hand, terminate with the curvature adjoining the rim base 10a without protruding beyond the rim base 10a '. The disks 11a, 11a ^! a bend running parallel to the curvature so that its inner ends close in the form of narrow webs 12. These webs 12 are at regular intervals

stands of spokes 11c, 11c * interrupted, which are arranged radially and each merge into the so-called flange plate 11d, 11d ^T.

In cross-section, the spokes lic, 11c ^! U-shaped extension heads 1le which start in the region of the rim walls 10b, 10c and merge into profiles with a funnel-shaped cross section. The openings of these profiles point inwards, ie they face the openings of the profiles of the opposing spokes 11c or 11c '. At the transition of the spokes lic, 11c ¹ into the flange plates 11d, 11d ^r , these are designed as beads 1lf on the edge, the openings of which face one another. The corrugations 11f rise outwardly in an arched manner from the flange plates 11d, 11d ^f in the axial direction and show rounded bulges between the transitions into the spokes 11c, 11c ^f.

In order to distribute the pressure transmitted from an axle 13 to the spokes 11 1 c, 11 c ^f as evenly as possible, the spokes 1 le connected to the disk 11 a are adjacent spokes H c by half a distance from the spokes 11 c ′ connected ^{to the disk 11 a f}

or 11c ^T offset from one another.

The flange plates 11d, 11d ^f have central collar holes 15a, 15b, the inside edge of which is flanged in the manner of a collar 15a ', 15b ¹ in the axial direction. Around these collar-like edges 15a ^f , 15b ^{1 is} a spacer tube 16 (spacer tube) representing an axle jacket. From the outside of the flange 11d, 11d ^! engage ball bearing shells 17a, 17b in the collar holes 15a and 15b, respectively. The ball bearing shells 17a, 17b show outer annular disks 17a ¹ , 17b ¹ acting as dust covers, which merge into pipe sockets within the collar holes 15a, 15b and are bent slightly inwards at the ends, whereby an inner axial limitation is given for annular ball bearings, which are arranged around an axis 13 with a continuous thread. Clamping sleeves 14, which are rotated with an internal thread on the axis 13, represent an outer axial limit. The clamping sleeves 14 protrude beyond the ball bearing shells 17a, 17b, and the ends of the axle 13 protrude beyond them.

In order to achieve a tight fit of the ball bearing shells 17a, 17b, they have a larger outer diameter

equipped as the collar holes 15a, 15b and thus secured against axial displacement in a press fit. ^{A safeguard against rotation is achieved by the fact that their ring disks 17a 1} , 17b ^l with an internal toothing 17c or the like are attached to the outer sides of the flange plates lld, lld '. are provided.

These ring disks 17a ^! , 17b ¹ form stop wheels which prevent the bearing shells 17a, 17b from being pushed too deeply into the spacer tube 16. They also secure the interior of the spacer tube 16 against the ingress of dust,

A multi-part rim base according to the inflation rate is special Suitable for bikes in which the individual parts are pre-finished and only need to be put together. This type of assembly is carried out; without welding, Riveting or the like.

In the case of such children's bicycles with a multi-part rim base, their individual parts refined after assembling z. B. be painted, it is appropriate, if necessary Special paint drainage grooves should be provided in the rim bed between the discs in the rim base «If the web between If the punched-out spokes are kept wider, it can be advantageous to use special ones that are guided through the webs

- 8 waste water drainage channels to be provided.

It is within the scope of the innovation to equip the paddling plates with slots, recesses or the like in order to these decorative caps or the like. to attach. The adapter sleeves can also be drawn into the ball bearing shells instead of sticking out of them. In a modified one Embodiment instead of the dust cover or ball bearing shells made of metal are made of Made of plastic like UyIon, which is more elastic Ensure storage of the axis.

A children's vehicle wheel according to the! Inflation stands out through simple industrial production (assembly line production) and great stability.
