"Roller skate roll"

The innovation concerns a roller skate roller with an outer one Rubber or plastic running ring. In this plastic running gear Both the inner and the outer bearing shell are pressed in from the inside. For outer cover of the bearing is a rod end cap put on.

The task of the innovation is to propose a dust protection cap, which completely covers both the bearing and the axle from the outside .

Fastenings of the dustproof cap are known in which this cap is clamped onto the roller axle by means of a nut. With this type of fastening, however, the nut and the Aohsenende remain visible from the outside. The dust-proof cap does not rotate with the roller and therefore does not provide the internal ball bearing with effective protection against dirt and dust.

However, there are also known attachments of the dustproof cap,

in which this cap has a complete closure to the outside and circulates with it. In these versions, the connection is the

Dust bowl with the balls as a result of the elasticity of the Roller material is not sufficiently reliable, so that the; Cap often falls out during normal heavy-duty use.

The innovation according to the feature of a roller skate role with a outer rubber or plastic running ring, pressed into it Bearing shells and an outer end cap for the bearing is that the Staubabsehlußkappe is rigidly connected to the outer bearing shell, such that the bearing and the Axis are completely covered from the outside. The dust cap is attached to the outer bearing shell with rivets, preferably three rivets are used.

With the new dust cap fastening, a '. · secure connection from metal to metal created without the material of the tread is stressed. The storage of the Holle is invisible from the outside and protected against the ingress of foreign bodies.

In addition, the innovation relates to all described, drawn and claimed features.

The accompanying drawing shows a section according to the innovation Roller skate. -

With 1 of the target running ring is referred to, the predominantly of rubber or a suitable plastic ". In this ball bearing rim are inside the "two bearing shells, namely the inner bearing shell 2 and the outer bearing shell 3, pressed in. These "two bearing shells" interlock for axial securing. The bearing shells are already used for the Ball barrel. A completely closed Staübabsehlußkappe 4 "is attached to the outer bearing shell 3, preferably with Meten 5. So-called hollow rivets can be used as metes will. The outer bearing shell 3 is expediently provided with holes which are arranged on a pitch circle. The Mete 5 are before inserting the outer bearing shell

3 with the plague head set inside. The Staübabsehlußkappe

4 has holes corresponding to those of the outer bearing shell 3 provided. The final attachment of the dust cap takes place after the roller shoelace has been assembled with its storage is. She is doing this with her Metlöehern on the above Meth halves attached and riveted.
