Short dumbbell
Disclosed is a dumbbell comprising a dumbbell bar ( 1 ) that is used as a handle ( 3 ), and weight plates ( 2 ) at the ends that can be plugged or clipped onto the dumbbell bar ( 1 ) and can be replaced with different weights; the weight plate ( 2 ) has an outer surface ( 5 ) that faces outward in the mounted state. The disclosed dumbbell is characterized in that the outer surface ( 5 ) is formed by an asymmetrically weight-loaded flywheel ( 6 ) which is mounted on the weight plate ( 2 ) so as to be parallel thereto and be able to rotate about a central axis in such a way that the flywheel ( 6 ) always has the same orientation or angular position.
1. A dumbbell with a dumbbell bar functioning as a handle, and weight plates on ends, which can be placed or slid onto the dumbbell bar, and can be exchanged with different weights, wherein the weight plates have an outer surface that faces outward when placed on the bar, characterized in that the outer surface is formed by an asymmetrically weighted flywheel, which is mounted on the weight plates, parallel thereto, such that the flywheel can rotate about a central axis, such that the flywheel always assumes the same orientation or angular position.
2. The dumbbell according to claim 1 , characterized in that the weight plates have a circumferential rim extending orthogonally away from the weight plate, which at least partially extends slightly above or around the weight plate.
3. The dumbbell according to claim 2 , characterized in that the rim is an integral component of the weight plate.
4. The dumbbell according to claim 2 , characterized in that the rim is made of plastic or rubber.
5. The dumbbell according to claim 1 , characterized in that the flywheel is flush with the rim of the weight plate.
6. The dumbbell according claim 1 , characterized in that the surface of the flywheel, and thus the outer surface of the weight plate, functions as an information medium, or is suitable for attaching a flat label.
7. The dumbbell according to claim 1 , characterized in that an information medium can be glued to the surface of the flywheel.
8. The dumbbell according to claim 1 , characterized in that the information medium contains the weight of the weight plate and/or further information.
9. The dumbbell according to claim 1 , characterized in that the grip formed by the dumbbell bar or encompassing the dumbbell bar can rotate.
10. A weight plate for a dumbbell that has a self-adjusting flywheel, which has the features according to claim 1 .
