Exercise device

1. An exercise device, comprising:

a multi-layer platform, and

a plurality of anchoring elements,

wherein the platform includes a soft upper layer, a rigid lower layer and a plurality of cavities passing through each of the upper layer and lower layer,

wherein the anchoring elements include ends removably connectable to the cavities of the platform,

wherein the rigid lower layer and the ends comprise matching surfaces allowing mutual connection of the platform and the anchoring elements,

wherein the rigid lower layer comprises at least multi-layer wood,

wherein the platform comprises a soft third layer, associated with the rigid lower layer, to prevent the platform from slipping relative to a floor surface,

wherein the third layer includes a plurality of recesses positioned beneath the plurality of cavities, the recesses being larger than the cavities such that an upper surface of each recess is partly formed by a lower surface of the lower layer;

wherein the ends include protuberances shaped to pass through the cavities in the upper layer and lower layer and, when aligned with the third layer, to be rotatable in the recesses with respect to the cavities to be positioned under the lower surface of the lower layer to prevent withdrawal of the anchoring elements without further rotation of the protuberances to again align with the cavities.

2. The device according to claim 1 , wherein the cavities are not through cavities.

3. The device according to claim 1 , wherein the third layer and the ends of the anchoring elements comprise matching surfaces, being designed to allow mutual connection of the platform and the anchoring elements.

4. The device according to claim 1 , wherein the end of each anchoring element comprises a stop, located above the protuberance, being designed to interact with the soft upper layer when the anchoring element is connected to the platform, in such a way as to stabilise a position of the anchoring element with respect to the platform.

5. The device according to claim 1 , wherein at least one of the anchoring elements comprises a rigid core, and at least one covering element, which can be removably associated with the core, in such a way as to create various device geometries.

6. The device according to claim 5 , wherein the rigid core comprises a transversal hole, designed to allow connection of two or more anchoring elements, in such a way as to create complex structures.

7. The device according to claim 1 , wherein the soft upper layer and the soft third layer comprise at least EVA material.

8. The device according to claim 1 , wherein the multi-layer platform comprises a plurality of through slots, designed to allow manual gripping of the device for moving and positioning the device.

9. The device according to claim 1 , and further comprising an elastic coupling system, designed to determine and stabilise the mutual connection position of the platform and the anchoring elements.

10. The device according to claim 1 , wherein the recesses are shaped to include generally arcuate portions that receive the shaped protuberances and, when the shared protuberances are aligned with the third layer, allow partial rotations of the anchoring elements with respect to the platform while preventing full rotations of the anchoring elements with respect to the platform.

11. An exercise device, comprising:

a multi-layer platform, and

an anchoring element,

wherein the platform includes a soft upper layer, a rigid lower layer and a plurality of cavities passing through each of the upper layer and lower layer,

wherein the anchoring element includes an end removably connectable to the cavities of the platform,

wherein the rigid lower layer and the end comprise matching surfaces allowing mutual connection of the platform and the anchoring element,

wherein the rigid lower layer comprises at least multi-layer wood,

wherein the platform comprises a soft third layer, associated with the rigid lower layer, to prevent the platform from slipping relative to a floor surface;

wherein the third layer includes a plurality of recesses positioned beneath the plurality of cavities, the recesses being larger than the cavities such that an upper surface of each recess is partly formed by a lower surface of the lower layer;

wherein the end includes a protuberance shaped to pass through the cavities in the upper layer and lower layer and, when aligned with the third layer, to be rotatable in the recesses with respect to the cavities to be positioned under the lower surface of the lower layer to prevent withdrawal of the anchoring element without further rotation of the protuberance to again align with the cavities.

12. The device according to claim 1 , wherein the cavities are not through cavities.

13. The device according to claim 11 , wherein the end of the anchoring element comprises a stop, located above the protuberance, being designed to interact with the soft upper layer when the anchoring element is connected to the platform, in such a way as to stabilise a position of the anchoring element with respect to the platform.

14. The device according to claim 11 , and further comprising an elastic coupling system, designed to determine and stabilise the mutual connection position of the platform and the anchoring element.

15. The device according to claim 11 , wherein the recesses are shaped to include generally arcuate portions that receive the shaped protuberance and, when the shaped protuberance is aligned with the third layer, allow partial rotation of the anchoring element with respect to the platform while preventing full rotation of the anchoring element with respect to the platform.
