Definitions

  • the present invention relates to an in-line skate with wheels arranged in three rows, and more particularly, to an in-line skate with wheels arrange in three rows, which can allow a beginner or skilled person to conveniently and safely use it, allow rapid turning at a rapid speed, and reduce load to a user' s ankle by mounting auxiliary wheels at right and left sides of main wheels of a conventional skate having several problems in that the user may be damaged at the ankle or frequently fall and cannot be on one foot as a distance between the bottom surface of a skating boot of the conventional in-line skate and the ground is too long and the wheels are arranged in a single row, and in that the conventional roller skate is too slow as a contact area between the wheels and the ground is wide and is disadvantageous in rapid turning as the user who must use it in a state where four wheels are in contact with the ground cannot inclined the user's feet much.
  • a conventional in-line skate has a number of wheels arranged in a single row, and so is fast and allows a dynamic exercise and rapid turning.
  • the conventional in-line skate has several problems in that the user may be damaged at the ankle or frequently fall and cannot be on one foot as a distance between the bottom surface of a skating boot and the ground is too long and the wheels are arranged in a single row.
  • the conventional in-line skate has another problem in that it cannot prevent the user from falling on the user's front and a beginner cannot learn in-line skating easily as a stopper for reducing speed is mounted only to the back of the skate.
  • a conventional roller skate has four wheels arranged in two rows like car wheels, and has advantages in that the beginner can learn roller skating easily and the roller skate is safer than the in-line skate as the user can be on one foot.
  • the conventional roller skate has several problems in that it is slow due to strong frictional force as a contact area between the wheels and the ground is wide, and in that the user cannot inclined the user's feet much and is disadvantageous in rapid turning as the user who must use it in a state where the four wheels are in contact with the ground.
  • the present invention has been made in view of the above problems, and it is an object of the present invention to provide an in-line skate, which has auxiliary wheels mounted at right and left sides of main wheels of a conventional skate, thereby allowing a beginner or skilled person to conveniently and safely use it, allowing rapid turning at a rapid speed, and reducing load to the user's ankle.
  • Another object of the present invention is to provide an in-line skate, which has auxiliary wheels having the outer diameter smaller than that of main wheels, arranged in a central row and being in contact with the ground when the in-line skate is moved, thereby reducing a rolling resistance due to unnecessary rolling of the auxiliary wheels .
  • a further other object of the present invention is to provide an in-line skate, which has stoppers mounted on at least one more portions of the front and rear parts of a frame, thereby preventing sliding.
  • the present invention provides an in-line skate according to a preferred embodiment of the present invention comprising: a frame fixed on the bottom surface of a general shoe by means of bolts; a number of main wheels arranged on the center of the lower end portion of the frame in the longitudinal direction in a row; wheel shafts for fixing the plural main wheels onto the frame; and a number of auxiliary wheels fit on the wheel shafts and mounted at right and left sides of the main wheels, which are arranged in a row, the auxiliary wheels having the outer diameter smaller than that of the main wheels.
  • stoppers are mounted on at least one or more portions of the front and rear parts of the frame .
  • the number of the auxiliary wheels is different from that of the main wheels.
  • auxiliary wheels have the same outer diameters as the main wheels, and wheel shafts of the auxiliary wheels are located above the wheel shafts of the main wheels.
  • FIG. 1 is a top view of an in-line skate having wheels arranged in three rows according to a preferred embodiment of the present invention
  • FIG. 2 is a bottom view of the in-line skate
  • FIG. 3 is a front view of the in-line skate
  • FIG. 4 is a rear view of the in-line skate

  • the auxiliary wheels 31 are arranged in the left row and in the right row, and so, the present invention has a structure where the wheels are arranged in the longitudinal direction in three rows.
  • the main wheels 30 and the auxiliary wheels 31 are mounted on the frame 20 by means of wheel shafts 32 and nuts 33, and at this time, one main wheel 30 and two auxiliary wheels 31 are mounted on the frame 20 through one wheel shaft 32.
  • stoppers 40 are mounted on the front or rear part of the frame 20, but may be mounted at both of the front and rear parts of the frame 20. The stoppers 40 are to reduce speed and prevent- a user from suddenly sliding and falling.
  • FIG. 3 is a front view of the in-line skate according to the present invention
  • FIG. 4 is a rear view of the in-line skate.
  • the present invention can reduce unnecessary rolling resistance of the auxiliary wheel 31.
  • the present invention provides the user with a stable posture as the user can stand in a state where the main wheels 30 and the auxiliary wheels 31 are all in contact with the ground.
  • general sports shoes can be used as the skating boots 10.
  • the auxiliary wheels 31 are used not only when the user stands on the ground but also when the user skates on the ground or rounds a curve during running.

  • FIG. 10 is a bottom perspective view showing the frame of the in-line skate according to the present invention.
  • the frame 20 used in the present invention has a structure similar to the frame of the conventional in-line skate where wheels arranged in a single row are mounted.
  • the frame 20 has female screws formed on portions of the front and rear parts thereof for mounting the stoppers 40.
  • the present invention is characterized in that the plural auxiliary wheels 31 are mounted at the right and left sides of the plural main wheels 30 arranged at the central portion of the frame 20, the auxiliary wheels 31 have the outer diameter smaller than that of the main wheels 30, and it is not necessary that the auxiliary wheels 31 have the same number as the main wheels 30. Moreover, it is not necessary that the auxiliary wheels 31 use the same shafts as the main wheels 30. In addition, the reason that the auxiliary wheels 31 have the outer diameter smaller than that of the main wheels 30 is to make mainly the main wheels 30 touch the ground.
  • the present invention can provide the same effect as the above structure.
  • the in-line skate according to the prevent invention has auxiliary wheels mounted at right and left sides of main wheels of the typical conventional inline skate, thereby allowing a beginner or skilled person to conveniently and safely use it, allowing rapid turning at a rapid speed, and reducing load to the user's ankle.
  • the in-line skate has the auxiliary wheels having the outer diameter smaller than that of the main wheels, which are arranged in the central row and are mainly in contact with the ground when the in-line skate is moved, thereby reducing a rolling resistance due to unnecessary rolling of the auxiliary wheels.
  • the in-line skate has the stoppers mounted on at least one more portions of the front and rear parts of the frame, thereby preventing sliding.

Abstract

L'invention concerne un patin en ligne comportant trois rangées de roues, qui permet à un débutant ou à une personne expérimentée d'apprendre à patiner de manière pratique et sûre ; de faire des virages à vitesse rapide ; et de réduire la charge appliquée sur la cheville de l'utilisateur. De plus, le patin en ligne comporte des roues auxiliaires dont le diamètre extérieur est inférieur à celui des roues principales, ce qui permet de réduire la résistance au roulement due au roulement superflu des roues auxiliaires. Ce patin comprend :un cadre fixé à la surface inférieure d'une chaussure ordinaire au moyen de boulons ; des roues principales placées sur une rangée au centre de la partie d'extrémité inférieure du cadre, dans le sens de la longueur ; des axes de roues pour fixer les roues principales sur le cadre ; et des roues auxiliaires, montées sur les axes de roues de part et d'autre des roues principales, sur une rangée. Le diamètre extérieur des roues auxiliaires est inférieur à celui des roues principales.
