Abstract

A chassis for a skating device comprising at least one retention element comprising at least one of a sliding surface, a barrel-shaped roller, an hourglass shaped roller, a cylinder shaped roller, a bearing ball, at least one ball and at least one turning element.

1 - 12 . (canceled) 
     
     
         13 . A chassis for a skating device comprising:
 (a) a retention element comprising one or more of:
 a sliding surface; 
 a barrel-shaped roller; 
 an hourglass shaped roller; 
 a cylinder-shaped roller; and 
 a bearing ball; 
   (b) a ball; and   (c) a turning element.   
     
     
         14 . The chassis for a skating device according to  claim 13 , further comprising:
 (d) a support for fixing to a boot;   (e) two or more axles, wherein ends of the axles are arranged to be attached to sidewalls of the chassis; and   (f) two or more turning elements, arranged on the axles and adapted to rotate around that axle.   
     
     
         15 . The chassis for a skating device according to  claim 13 , wherein the turning element comprises one or a combination of:
 (g) a roller;   (h) a ball;   (i) a wheel; and   (j) a sliding surface.   
     
     
         16 . The chassis for a skating device according to  claim 13 , wherein the turning element comprises a bearing, arranged between the turning element and an axle and adapted to reduce kinetic friction between the turning element and the axle. 
     
     
         17 . The chassis for a skating device according to  claim 13 , wherein the turning element is configured as a semicircular shell with spherical cutouts to act as a retention element. 
     
     
         18 . A skating device comprising the chassis according to  claim 13 . 
     
     
         19 . A method for manufacturing a chassis for a skating device particularly according to  claim 13 , the chassis configured to comprise:
 (a) a retention element comprising a combination of:
 a sliding surface; 
 a barrel-shaped roller; 
 an hourglass shaped roller; 
 a cylinder-shaped roller; and 
 a bearing ball; 
   (b) at least one ball; and   (c) at least one turning element.   
     
     
         20 . The method for manufacturing a chassis for a skating device according to  claim 19 , allowing the chassis for a skating device to further comprise:
 (d) a support for fixing a boot;   (e) two or more axles, wherein ends of the axles are arranged to be attached to sidewalls of the chassis; and   (f) two or more turning elements, arranged on the axles and adapted to rotate around that axle.   
     
     
         21 . The method for manufacturing a chassis for a skating device according to the  claim 19 , wherein the two or more turning elements comprise a combination of one or more of:
 (g) a roller;   (h) a ball;   (i) a wheel; and   (j) a sliding surface.   
     
     
         22 . The method for manufacturing a chassis for a skating device according to  claim 19 , allowing the turning element to comprise a bearing arranged between the turning element and an axle and adapted to reduce kinetic friction between the turning element and the axle. 
     
     
         23 . The method for manufacturing a chassis for a skating device according to  claim 19 , wherein the turning element is configured as a semicircular shell with spherical cutouts to act at the same time as retention element. 
     
     
         24 . The method for manufacturing a skating device according to  claim 19 , allowing a skating device to comprise the chassis.
