Abstract
A dynamic exercise device having a hand grip mounted in an inner ring, the inner ring mounted in an outer ring, and the outer ring mounted in a base. The inner ring, outer ring and base are each movable in at least one degree of freedom relative to each of the others. The base further includes a first support strut, a second support strut, and a bridge member interconnecting the first and second support struts and having a planar surface-engaging face configured to engage a surface on or against which the exercise device is used.
Claims18
An exercise device comprising:
- a base including a first support strut, a second support strut, and a bridge member interconnecting the first and second support struts and having a planar surface-engaging face configured to engage a surface on or against which the exercise device is used;
- and
- a handle having a first end and a second end opposite to said first end, a grip, an inner ring in which the grip is rotatably mounted, and an outer ring in which the inner ring is rotatably mounted, the handle being rotatably coupled to the base via a first bearing at the first end of the handle and a second bearing at the second end of the handle;
- wherein the first bearing and the second bearing of the handle define a first axis about which the handle is configured to rotate relative to the base, the first axis being parallel with the surface;
- wherein at least one of the first bearing and the second bearing comprises an adjustment element configured to selectively limit a degree of rotation of the handle about the first axis;
- and
- wherein one of the inner ring and the outer ring comprises an annular rail which is captive within a slot formed in the other of the inner ring and the outer ring, the annular rail being sized to slide freely around the slot about a second axis.

- a base including a first support strut, a second support strut, and a bridge member interconnecting the first and second support struts and having a planar surface-engaging face configured to engage a surface on or against which the exercise device is used;
- and
- a handle having a first end and a second end opposite to said first end, a grip, an inner ring in which the grip is rotatably mounted, and an outer ring in which the inner ring is rotatably mounted, the handle being rotatably coupled to the base via a first bearing at the first end of the handle and a second bearing at the second end of the handle;
- wherein the first bearing and the second bearing of the handle define a first axis about which the handle is configured to rotate relative to the base, the first axis being parallel with the surface;
- wherein at least one of the first bearing and the second bearing comprises a first adjustment element configured to selectively limit a degree of rotation of the handle about the first axis;
- wherein the inner ring rotates in the outer ring about a second axis which is perpendicular to the first axis;
- wherein one of the inner ring and the outer ring comprises an annular rail which is captive within a slot formed in the other of the inner ring and the outer ring, the annular rail being sized to slide freely around the slot about the second axis;
- and
- wherein the inner ring comprises a second adjustment element which limits a degree of rotation of the grip about the second axis.
