Multi-zonal roller and method of use thereof
The present invention generally relates a multi-zonal and non-circular roller with several different zones along the periphery of the roller's outer surface and more specifically a roller having a non-circular internal area, a non-regular external surface covered by a series of multiple shape and angles designed to include to offer a user different types of resistance and muscle relief, including a point for the management of a myofascial trigger point.
1. A multi-zonal roller for therapeutic, fitness, and sports enhancement device, comprising:
a thin-walled tube with a thickness, a width, and an outside surface; and
an external shell of soft polymer with an internal surface in contact with the outside surface of the thin-walled tube, wherein the external shell has a variable thickness defining an outer surface of use for therapeutic, fitness, and sports enhancement by contact with a user body, wherein the variable thickness circumferentially defines a plurality of zones each opposite along the circumference of a tip point;
wherein the external shell includes three tip points and the plurality of zones includes three zones each covering approximately 120 degree circumferentially of the roller and wherein each zone is delimited by two of the three tip points; and
wherein a first zone is defined by a series of small semi-circular central longitudinal bumps along the width of the roller and flanked by two more longitudinal bumps of identical geometry at a distance along the first zone to create a first flat portion between the small semi-circular central bumps and the flanking bumps.
2. The multi-zonal roller of claim 1 , wherein the thin-walled tube is generally oblong.
3. The multi-zonal roller of claim 2 , wherein one of the two oblong axis is longer than the other by a ratio of 1.05 to 1.40.
4. The multi-zonal roller of claim 1 , wherein a second zone is defined by a series of larger semi-circular central longitudinal bumps along the width of the roller and flanked by two more longitudinal larger bumps of identical geometry as the larger semi-circular central longitudinal bumps at a distance along the second zone to create a second flat portion between the larger semi-circular central longitudinal bumps and the flanking bumps.
5. The multi-zonal roller of claim 4 , wherein a third zone is defined by a third flat area with a semi-straight area.
6. The multi-zonal roller of claim 1 , wherein at least one of the three tip points includes a semi-rounded point with a flat side on one side leading to one of the three zones and a flat side on the other side leading to another of the three zones.
7. The multi-zonal roller of claim 1 , wherein the soft polymer forming the external shell of each of the three zones has a different density.
8. A method of use of a multi-zonal roller for therapeutic, fitness, and sports enhancement device, the method comprising the steps of:
selecting a multi-zonal roller comprising of a thin-walled tube with a thickness, a width, and an outside surface, and an external shell of soft polymer with an internal surface in contact with the outside surface of the thin-walled tube, wherein the external shell has a variable thickness defining an outer surface of use for therapeutic, fitness, and sports enhancement by contact with a user body, wherein the variable thickness circumferentially defines a plurality of zones each opposite along the circumference of a tip point, wherein the external shell includes three tip points and the plurality of zones includes three zones each covering approximately 120 degree circumferentially of the roller and wherein the each zone is delimited by two of the three tip points, wherein a first zone is defined by a series of small semi-circular central longitudinal bumps along the width of the roller and flanked by two more longitudinal bumps of identical geometry at a distance along the first zone to create a first flat portion between the small semi-circular central bumps and the flanking bumps;
placing on the ground at least one of the tip points;
contacting a portion of a user's body against one of the plurality of zones at the opposite side of the roller; and
pivoting around the tip point the roller by moving the user's body as to allow the zone to contact the user's body.
9. The method of claim 8 , wherein the thin-walled tube is generally oblong.
10. The method of claim 9 , wherein the device includes structure where one of the two oblong axis is longer than the other by a ratio of 1.05 to 1.40.
11. The multi-zonal roller of claim 8 , wherein a second zone is defined by a series of larger semi-circular central longitudinal bumps along the width of the roller and flanked by two more longitudinal larger bumps of identical geometry as the larger semi-circular central longitudinal bumps at a distance along the second zone to create a second flat portion between the larger semi-circular central longitudinal bumps and the flanking bumps.
12. The method of claim 11 , wherein a third zone is defined by a third flat area with a semi-straight area.
13. The method of claim 12 , wherein at least one of the three tip points includes a semi-rounded point with a flat side on one side leading to one of the three zones and a flat side on the other side leading to another of the three zones.
14. The method of claim 8 , wherein the soft polymer forming the external shell of each of the three zones has a different density.
