The present invention relates to fitness, exercise and massage rollers. More precisely the present invention relates to a fitness, exercise and massage roller according to the preamble part of claim 1.
It is known from prior art to use fitness, exercise and massage rollers for relieving the tightness muscles and treatment of fasciae. The fitness, exercise and massage rollers are also used in different types of muscles and fasciae treatments of active, passive and other persons having need for the corresponding treatment. These rollers are generally made of plastic, foam, or rubber and the rollers currently on the market can have a smooth or a textured surface. One type of massage devices is the fitness, exercise and massage roller, often called as foam roller, which is often used by placing the roller below the body part needing massage and rolling the body part against the roller and the body weight creating thus the massage force. The foam rollers are used in different types of exercises and are typically solid foam structures with a smooth surface or with a surface with different types of protrusions. The surface structure of different types of foam rollers may be produced of different hardness values depending on desired results and/or on types of use. Foam rollers are most typically used on a floor such that desired body part of a user is placed on the foam roller located on the floor. The user shifts his/her weight on the foam roller and performs longitudinal or transversal movements creating a massage effect. In some applications the foam roller may be raised up from the floor in case selected exercise can be performed better when the foam roller is in raised position.

During the course of the following description like numbers and signs will be used to identify like elements according to the different views which illustrate the invention and its advantageous examples. In the figures some repetitive reference signs may have been omitted for clarity reasons.
In the description of the figures the terms upper and lower, as well as terms horizontal and vertical are used in view of normal use position of the fitness, exercise and massage roller. The terms front and back are used in view of the normal position of the user in the fitness, exercise and massage roller.
In the figures is shown examples of a fitness, exercise and massage roller 10 (in the following “roller”), which has an outer cylindrical form and a hollow opening 13 around its imaginary center axis. The roller 10 comprises two frame parts 11, 12, which are semicircular in their outer form and comprise recesses that form the hollow opening 13. The frame parts 11, 12 are advantageously substantially identical and symmetrical, as well as formed in a way that they fit to each other when aligned to form a full cylindrical form. Thus, the frame parts 11, 12 can be produced by one mold.
The frame parts 11, 12 are attached turnably to each other on one longitudinal side by at least one hinge 17 such, that the frame parts 11, 12 are turnable towards or away from each other providing the opening and closing of the roller 10. The hinge 17 is formed of hinge structures 17B formed on the frame parts 11,12 and are hinged with a hinge axis 17A through holes of the hinge structures 17B formed on the frame parts 11, 12.
The roller 10 further comprises locking means 21, 22 for securing the closed position of the frame parts 11, 12 of the roller 10. The locking mechanism 21, 22 are advantageously located at least at one end or side or opposing inside faces of frame parts 11,12 of the roller 10. In case the hinge 17 has a high spring-back factor the locking mechanism 21, 22 can be omitted.
The roller 10 also comprises on each frame part 11, 12 recesses 28, 29 on opposite longitudinal side in relation to the hinge 17 providing an opening point of the frame parts 11, 12 for easy turning of the frame parts 11, 12 away from each other around the hinge 17 by gripping with fingers after the locking mechanism 21, 22 have been opened.
The roller also comprises adjusting rotation elements 15, which will be located around the bar 51 or like, when setting the roller 10 for use. The adjusting rotation element 15 is located in and supported by a wall element 14, which wall element 14 in turn is supported to the corresponding frame part 11, 12. The adjusting rotation elements 15 are movable in radial direction i.e. in perpendicular direction in relation to the surface of the wall elements 14 and to the surface of the hollow opening 13 to adjust the roller 10 for bars 51 or like with different diameters. When the roller 10 is set around a bar 51, the roller 10 with the frame parts 11, 12 in opened position is set at the selected location at the bar 51. Then, the frame parts 11, 12 are turned to closed position around the hinge 17 such, that the bar 51 inside the hollow opening 13 is centered as the adjusting rotation elements 15 will set to the corresponding radial position around the bar 51. In case the adjusting rotation elements 15 are manually adjustable for setting the roller 10 around the bar 51, while the frame parts 11, 12 of the roller 10 are in opened position, the adjusting rotation elements 15 are set to desired radial position such, that the bar 51 inside the hollow opening 13 will be centered as the radial position of the adjusting rotation elements 15 will set the roller 10 to the corresponding radial position around the bar 51 and the roller 10 is set at the selected location at the bar 51. Then, the frame parts 11, 12 are turned to closed position around the hinge 17. The locking mechanism 21, 22 are locked and thus the roller 10 is rotatably around the bar positioned at its place. When the roller 10 is to be removed the locking mechanism 21, 22 are opened and the frame parts 11, 12 are turned around the hinge 17 away from each other by gripping to the recesses 28, 29 and then, the roller 10 can be taken to a new position. The meeting surfaces of the frame parts 11, 12 also comprise a groove-protrusion fitting 18, 19 for preventing sliding of the frame parts in respect of each other.
The roller 10 comprises advantageously around its outer circumferential surface a padding of elastic material. The hardness of the padding can be selected for example in view of the desired usage. The outer circumferential surface of the roller 10 can be smooth or shaped. The padding and/or directly the outer circumferential surface of the roller 10 can be shaped. It can be for example be shaped with different shapes of different heights and have a ball-like, a serrated etc. profile.
The wall elements 14 of the roller 10 are advantageously of hard, supporting material, for example plastic material. The frame parts 11, 12 of the roller 10 are advantageously of slightly elastic or foamy plastic material.
The adjusting rotation elements 15 can be constructed of different types of bearings, ball bearings, annular ball bearing, circumferential bearing, sliding bearing, wheels etc. and comprises moving mechanism configured to provide the radial, adaptive movement of the adjusting rotation elements 15 for adapting the fastening of the roller 10 around bars of different sizes and cross-sectional shapes. The moving mechanism i.e. height adjustment mechanism can be for example based on staggered shapes, fitting pieces, springs or turnable threads. The adjusting rotation elements 15 are mounted inside the roller 10 at selected longitudinal locations, spaced apart such, that centering and adaptation of the roller 10 around the bar is provided. Advantageously, in longitudinal direction there is at least two adjusting elements in each frame part 11, 12. The adjusting rotation elements 15 may also comprise for example a brake mechanism for adjusting the rotational resistance for providing different exercise effect.
