Abstract

The device is provided with a reinforced area (4) and a valve (1) for being inflated and for the release of the air after use. It can be attached to the small wheels of a shopping trolley, a push chair, or other item when it has to moved across a soft surface as on the beach or on muddy grounds. A string (2), accommodated in a hem (3) around the inner area can be used for fastening.

Description

Bei der im Schutzanspruch 1 angegebenen Erfindung handelt es sich um ein einteiliges Hilfsrad – mit einer dazugehörende Sicherungsvorrichtung – das das Schieben bzw. Ziehen von ein- oder mehrachsigen Lauf-, Boller- und Kinderwagen (oder ähnlichen Gefährten) auf lockerem Untergrund wie z.B. Sand oder Schnee erleichtert, da es die Lauffläche der serienmäßig montierten Räder verbreitert.In the invention specified in protection claim 1 it is a one-piece auxiliary wheel - with an associated safety device - that Pushing or pulling of single or multi-axle carriages, bollards and prams (or similar companions) on a loose surface such as Sand or snow relieved there it the tread of the fitted as standard Widened wheels.

Das Hilfsrad ist dadurch gekennzeichnet, daß es durch Aufblasen mittels des Ventils (1) formschlüssig über das bereits vorhandene Rad gestülpt wird. Um ein unbeabsichtigtes Abrutschen des Hilfsrades zu verhindern wird es mittels eines Spannseils (2), das durch Schlaufen (3) die ein Teil des Grundkörpers sind geführt wird, in seiner Position gehalten. Das Spannseil verhindert auch eine unbeabsichtigte, unvorteilhafte Formveränderung des Hilfsrades bei übermäßiger Befüllung. Der Grundkörper verfügt außerdem über eine Stützkonstruktion (4), die ihm im Falle eines Teilverlusts der Füllung hilft, die Funktion des Hilfsrades aufrecht zu erhalten.The auxiliary wheel is characterized by being inflated by means of the valve ( 1 ) is slipped over the existing wheel in a form-fitting manner. To prevent the auxiliary wheel from accidentally slipping off, use a tensioning cable ( 2 ) by loops ( 3 ) which are part of the base body is held in position. The tensioning rope also prevents an unintentional, unfavorable change in shape of the auxiliary wheel in the event of excessive filling. The base body also has a support structure ( 4 ), which helps him to maintain the function of the auxiliary wheel in the event of a partial loss of the filling.
