  • Patent number: 4549591
    Abstract: The invention relates to a device for fitting and fixing gripping shoes on vehicle wheels. Four gripping shoes are fitted at the one end of respective arms which, after being fitted on the wheel, form a cross. The other ends of the arms of the gripping shoes are toothed and the arms are slidingly suspended in their longitudinal directions relative to a housing centrally situated with respect to the wheel and are movable by means of a gear wheel, rotatably mounted in the housing. The gear wheel engages with the teeth on the arms and is rotatable by means of an operating mechanism. The centrally situated housing is shaped from one piece in which there are arranged four channels for slidingly suspending and guiding the arms of the gripping shoes. The channels are running from the lower part and in the same plane on each of the short sides of the centrally situated housing and are running out at the upper part and in the same plane on opposite short sides of the centrally situated housing.
