Abstract

The invention relates to a fitness device consisting of a cylindrical body in which the handles are mounted horizontally against each other. The body consists of two coaxial rings, inner ring and outer ring, which are positioned in a reciprocally sliding or rolling relation, the inner ring on its inner surface is equipped with a housing for holding the handles; the axis of the handle being at a height, which is less than ½ of the outer diameter of the body at the place of the housing of the location of handles from the outer surface of the outer ring; and the handles are bent upwards. The connection between the handles and the handle-holding case is dismountable and the outer surface of the outer ring is provided with a rubber surface.

Claims (20)

1. A fitness device, comprising:

a cylindrical body including handles that are mounted horizontally against each other, characterized in that the body includes,

inner and outer coaxial rings which are positioned in a reciprocally sliding or rolling relation, wherein the body has a minimum width of 100 mm and an outer diameter;

the inner ring has an inner surface equipped with a housing for holding the handles, wherein the housing extends longitudinally beyond edges of the inner ring and outer ring, the handles are of a circular cross-section and are placed in the housing horizontally against each other, an axis of the handles being at a height which is less than ½ of the outer diameter of the body, the axis of the handles being located where the handles extend from the outer ring, and each of the handles has a horizontal grip part and a bent grip part, each bent grip part is bent upwards, at respective ends of the handles, relative to the axis of the handles at an external angle of less than 90°, a connection between the handles and the housing is dismountable and the outer surface of the outer ring is provided with a rubber surface.

2. The fitness device according to claim 1 , characterized in that an outer surface of the outer ring is a rubber surface that is textured.

3. The fitness device according to claim 1 , characterized in that the axis of the handles is located at a height of 63 mm from an outer surface of the outer ring.

4. The fitness device according to claim 1 , characterized in that the handles are bent upwards at respective ends thereof relative to the axis of the handles at an external angle of 55°.

5. The fitness device according to claim 1 , characterized in that a length of a horizontal part of the handles is at least 96 mm.

6. The fitness device according to claim 1 , characterized in that a surface of the handles is made of rubber.

7. The fitness device according to claim 6 , characterized in that the rubber surface of the handles is textured.

8. The fitness device according to claim 1 , characterized in that the housing extends longitudinally beyond edges of the body.

9. A fitness device, comprising:

a cylindrical body defining a central rolling axis and an outer rolling surface, the body including inner and outer coaxial rings which are positioned in a reciprocally sliding or rolling relation;

a housing mounted to an inner surface of the inner ring of the body, wherein the housing extends longitudinally beyond edges of the inner ring and outer ring and

handles mounted horizontally in the housing and extending outwardly therefrom, each handle having a horizontal grip part and a bent grip part, the horizontal grip parts defining an axis of the handles that is offset from the rolling axis of the body, each bent grip part being bent toward the rolling axis of the body with respect to the axis of the handles at an external angle of less than 90°.

10. The fitness device according to claim 9 , characterized in that the axis of the handles is at a height which is less than ½ of an outer diameter of the body.

11. The fitness device according to claim 9 , characterized in that the handles are removably mounted to the housing.

12. The fitness device according to claim 9 , characterized in that the housing extends longitudinally beyond edges of the body.

13. The fitness device according to claim 9 , characterized in that each handle has a circular cross-sectional shape.

14. The fitness device according to claim 9 , characterized in that the outer surface of the body is a rubber surface.
