View Patent ↗A sports dumbbell comprises a grip section ( 2 ), which runs along a grip shaft (L 1 ), and a support shaft (L 2 ) of a support section ( 3 ) spaced apart from the grip section ( 2 ) perpendicular to and running parallel to the grip shaft (L 1 ). The support section is connected at at least one end to the grip section ( 2 ). The sports dumbbell has a center of gravity (S) which is arranged within the support section ( 3 ). A distance (d 2 ) between the grip shaft (L 1 ) and the support shaft (L 2 ) is at least 11 cm, and an external shape of the sports dumbbell forms a closed annular body or open annular body.
1. A sports dumbbell comprising:
a grip portion ( 2 ) running along a grip axis (L 1 );
a support portion ( 3 ) including a support axis (L 2 ), wherein the support axis (L 2 ) is spaced from the grip portion ( 2 ) and runs parallel to the grip axis (L 1 );
wherein along the support axis (L 2 ) the support portion ( 3 ) has mutually opposing first and second ends and at least one of the first and second ends of the support portion ( 3 ) is connected to the grip portion ( 2 ), wherein a distance (d 2 ) between the grip axis (L 1 ) and the support axis (L 2 ) is at least 11 cm, wherein an outer shape of the sports dumbbell is fixed and substantially U-shaped, and wherein the sports dumbbell has a center of gravity (S) located inside the support portion ( 3 ) such that the sports dumbbell can be used in a manner that no torque is provoked in a user's wrist or arm; and
an end of a length-adjustable strap ( 8 ) provided on each of a first and a second end of the grip portion, the length-adjustable strap configured to be held behind a heel of the user when a foot tip of the user is extended through a passage opening ( 7 ) formed between the grip portion ( 2 ) and the support portion ( 3 ) wherein the first and second ends of the grip portion ( 2 ) are mutually opposing along the grip axis (L 1 ), the first end of the grip portion ( 2 ) is connected to the first end of the support portion ( 3 ) by a first connecting portion ( 4 ), and the second end of the grip portion ( 2 ) has no direct connection to the second end of the support portion ( 3 ).
