Training apparatus
The invention relates to a training apparatus, in particular for the muscle system of the hand, arm and upper body, wherein the apparatus has an elongate casing with at least an essentially circular internal cross section, in the interior of which at least one ball ( 5 ) is situated in a freely movable manner between shock absorbers ( 6 ). There are various forms of such training apparatuses. Their disadvantages include relatively monotonous training and the difficulty or impossibility of using them to train during another activity, for example during running. In order to avoid this, the invention is characterized in that the casing is of flexible design over at least part of its longitudinal extent, in that the ends of the casing are fastened to a handle part, and in that handle part and casing lie at least essentially on one plane.
1. An exercise apparatus, especially for exercising the muscles of the hands, arms, and upper body, with an elongated casing with an inner cross section that is at least essentially circular, where the interior of the casing contains at least one ball ( 5 ) that can move freely between shock absorbers ( 6 ), wherein the casing has a flexible construction over at least a portion of its longitudinal extent, where the ends of the casing are attached to a gripping part, and where the casing and the gripping part lie at least essentially in a plane, wherein the gripping part is pushed over a piece of flexible tubing ( 3 ), which in turn is pulled over a rigid tube ( 4 ), where the ends of the casing are pushed over the flexible tubing ( 3 ) until they reach the grip ( 2 ).
2. An exercise apparatus in accordance with claim 1 , wherein the casing consists of a plastic spiral tube ( 1 ).
3. An exercise apparatus in accordance with claim 1 , wherein the gripping part consists of a grip ( 2 ) that is at least essentially linear.
4. An exercise apparatus in accordance with claim 3 , wherein the shock absorbers ( 6 ) are arranged near the ends of the flexible tubing ( 3 ).
5. An exercise apparatus in accordance with claim 1 , wherein the balls ( 5 ) are made of steel.
6. An exercise apparatus in accordance with claim 1 , wherein the rigid tube ( 4 ) is made of steel, aluminum, copper, or their alloys.
7. An exercise apparatus in accordance with claim 2 , wherein the balls ( 5 ) have a diameter (L) which, when divided by the distance (M) from spiral ridge to spiral ridge of the spiral tube ( 4 ), does not yield a quotient that is a whole number.
8. An exercise apparatus in accordance with claim 1 , wherein the spiral tube ( 1 ) has a length of 40-100 cm, preferably 60-80 cm, and a diameter of about 22 mm, where the rigid tube ( 4 ) is a copper tube with a diameter of about 18 mm and a length of 20-30 cm, where the flexible tubing ( 3 ) has a diameter of about 20 mm and a length of 20-33 cm but with the condition that it extends beyond both ends of the rigid tube ( 4 ), where a shock absorber ( 6 ) is inserted in both ends of the piece of flexible tubing ( 3 ), and where four to seven steel balls ( 5 ) with a diameter of about 22 mm are provided in the spiral tube ( 1 ).
