Rolling device steered using the tilting angle and comprising offset rollers

Abstract

The aim of the invention is to improve inline skates so as to provide stability during skating, good acceleration, and added skating fun by having the skates turn more or less in accordance with the tilting angle. Said aim is achieved by a rolling device in which the rollers that are arranged largely one behind another are rotatably mounted in individual roller supports, the roller supports are pivotally attached to the chassis by means of inclined shafts, and the rollers are disposed in a laterally offset manner relative to the center line. In a simple embodiment depicted in FIGS. 4 a and b, the steering unit is composed of two respective rollers ( 2 ) which are mounted in a rocker-type roller support ( 3 ″) in an offset manner relative to one another by a distance ( 9 ). The roller support ( 3 ″) is pivotally attached to the chassis (not depicted) by means of a shaft ( 8 ) which extends at an angle α relative to the horizontal line. The rolling device generally comprises two steering units encompassing a total of four rollers.

1 . A tilt-steered rolling device comprising an optional application part, e.g. shoe, rolling ski binding or board, a chassis and at least one steering group, wherein the steering group consists of two steering units, which may also be combined in one piece, wherein the steering unit consists of one roller support and at least one roller which is rotatably mounted to the roller support, and wherein the roller support has a pivot shaft attached to the chassis, characterized in that the frontal projection of the pivot axis  4  extends at an acute angle α relative to the horizontal line  5  and the trace  6  of the at least one roller  2  is disposed in a laterally offset manner parallel to the longitudinal midline  7  of the rolling device. 
     
     
         2 . A rolling device as claimed in  claim 1 , wherein the steering group comprises two roller supports  3 ,  3 ′ including two rollers, where each roller  2  is rotatably mounted to one roller support. 
     
     
         3 . A rolling device as claimed in  claims 1  and  2 , which incorporates two steering groups. 
     
     
         4 . A rolling device as claimed in  claim 1  wherein the steering group consists of one roller support  3 ″ and two rollers  2 . 
     
     
         5 . A rolling device as claimed in  claims 1 ,  2  and  3 , wherein the two front rollers  2  of the respective steering groups have traces  6  at the one side of the axis of tilt  7  and the two rear rollers  2  of the respective steering groups have their traces at the other side of the axis of tilt  7 , and wherein the angles α, α′ which extend between the pivot axes  4 ,  4 ′ of the two front roller supports  3 ,  3 ′ and the horizontal line  5  are opposite to the angles α, α′ which extend between the pivot axes  4 ,  4 ′ of the two rear roller supports  3 ,  3 ′ and the horizontal line  5 . 
     
     
         6 . A rolling device as claimed in  claims 1  and  4 , wherein the two front rollers  2  of the respective twin-roller support  3 ″ have their traces  6  at the one side of the axis of tilt  7  and the two rear rollers  2  of the respective twin-roller support  3 ″ have their traces at the other side of the axis of tilt  7 , and wherein the angle a which extends between the pivot axis  4  of the twin-roller support  3 ″ and the horizontal line  5  is opposite to the angle α which extends between the pivot axis  4  of the rear twin-roller support  3 ″ and the horizontal line  5 . 
     
     
         7 . A rolling device as claimed in  claim 1 , wherein the respective two rollers of the two steering groups have traces which are disposed in a laterally offset manner relative to one another by different distances  9  and/or where the angles α, α′ of the pivot axes  4  of the roller supports  3 ″ which extend relative to the horizontal line  5  are not equal. 
     
     
         8 . A rolling device as claimed by  claim 1 , wherein the roller supports  3 ,  3 ′,  3 ″ return to their straight steering neutral position by means of elastic elements  14 .
