Abstract
To provide inline skates that prevent skidding when curving and turning, and enable stable curving turns to be performed while maintaining straight running speed. An inline skate has a plurality of running wheels arranged in a row in series in the running direction. Wheel shafts of curving wheels have axial directions that are orthogonal to the axial directions and running directions of the wheel shafts of the running wheels, respectively. When the inline skate is upright, ground surfaces of the plurality of curving turn wheels are located at a position higher than the sliding surface and on both sides of the inline skate.
Claims5
An inline skate, comprising:
- a wheel frame;
- a plurality of running wheels arranged in a row in series in a running direction;
- and
- a plurality of curving wheels arranged to the wheel frame, each curving wheel having a wheel shaft in an axial direction orthogonal to an axial direction of a wheel shaft of each running wheel and the running direction, respectively;
- said wheel frame further comprising:
- an upper plate and a lower plate each being longer in the running direction than in a width direction and facing each other in a vertical direction;
- connecting portions connecting front and rear sections of the upper plate and the lower plate in the running direction;
- parallel flange portions respectively protruding forward from the connecting portion connecting the front section of each of the upper plate and lower plate;
- and
- parallel flange portions respectively protruding rearward from the connecting portion connecting the rear section of each of the upper plate and lower plate;
- through holes in which the wheel shafts of the running wheels are mounted between the flange portions protruding forward and between the flange portions protruding rearward, respectively;
- through holes in which the wheel shafts of the curving wheels are mounted between the upper plate and the lower plate in a row in series;
- and
- a shoe mounted on an upper surface of the upper plate.
A wheel frame for inline skate in which a plurality of running wheels are arranged in a row in series in a running direction, comprising;
- a plurality of curving wheels having wheel shafts whose axial directions are orthogonal to axial directions of wheel shafts of the running wheels and the running direction;
- an upper plate and a lower plate being longer in the running direction than in a width direction and facing each other in a vertical direction;
- connecting portions connecting front and rear sections of the upper plate and the lower plate in the running direction;
- parallel flange portions respectively protruding forward from the connecting portion connecting the front section of each of the upper plate and lower plate;
- and
- parallel flange portions respectively protruding rearward from the connecting portion connecting the rear section of each of the upper plate and lower plate;
- through holes in which the wheel shafts of the running wheels are mounted between the flange portions protruding forward and between the flange portions protruding rearward, respectively;
- through holes in which the wheel shafts of the curving wheels are mounted between the upper plate and the lower plate in a row in series;
- and
- wherein a shoe is mounted on an upper surface of the upper plate.
An inline skate in which a plurality of running wheels are arranged in a row in series in a running direction, comprising:
- a plurality of curving wheels having wheel shafts whose axial directions are orthogonal to axial directions of wheel shafts of the running wheels and the running direction;
- wherein ground surfaces of the plurality of curving wheels are located at positions higher than sliding surfaces on which the running wheels are grounded, and at positions on both sides of the inline skate;
- and
- wherein the wheel shafts of the plurality of curving wheels rotate at a position higher than diameter of the plurality of running wheels.
