Abstract

The invention relates to a new design for a dumbbell with a dumbbell handle element and at least one holder for removable fastening of one or more weight disks on one end of the dumbbell handle element.

Claims

1. A dumbbell with a dumbbell handle element and with at least one holder for removable fastening of one or more weight disks on one end of the dumbbell handle element, wherein the at least one holder comprises a casing, the interior of which is open on a front side facing away from the dumbbell handle element for insertion and removal of the weight disks, and that locking means are provided on the casing that act in combination with the weight disks on their outer circumference.

6. The dumbbell as claimed in claim 1, further comprising locking means provided on the casing that act radially upon the weight disks on their outer circumference.

7. The dumbbell as claimed in claim 6, wherein the locking means consist of at least one swiveling locking element which locks the weight disks accommodated in the interior of the casing by interlocking on their outer circumference.

8. The dumbbell as claimed in claim 6, wherein the locking means consist of at least one swiveling locking element, which locks the weight disks accommodated in the interior in recesses with an edge area.

9. The dumbbell as claimed in claim 8, wherein the edge area of the weight disks is an outer circumference of these disks.

10. The dumbbell as claimed in claim 8, wherein the edge area consists of an opening of the respective weight disk.

11. The dumbbell as claimed in claim 8, further comprising recesses interlocking with the edge area of the weight disks formed on the inner surface of the casing.

12. The dumbbell as claimed in claim 11, wherein the recesses holding the edge area of the openings of the weight disks are formed on a journal located in the interior of the casing.

13. The dumbbell as claimed in claim 1, wherein in the interior of the casing on an inner surface of an outer wall of the casing and/or on a journal located in the interior, there is a rubber-elastic bearing surface for the weight disks.

14. The dumbbell as claimed in claim 1, wherein the weight disks are rubber-elastic at least on an area bearing against the casing when the locking element is locked and/or against a journal located in the casing

15. The dumbbell as claimed in claim 1, wherein the locking means consist of at least one swiveling cam located on the casing.

16. The dumbbell as claimed in claim 1, wherein the locking means consist of at least one swiveling locking element, which locks the weight disks accommodated in the interior in recesses with an edge area.

17. The dumbbell as claimed in claim 1, wherein locking means are provided on the casing that act radially upon the weight disks on their outer circumference.

18. The dumbbell as claimed in claim 1, wherein the at least one holder consists of a casing, the interior of which is open on a front side facing away from the dumbbell handle element for insertion and removal of the weight disks, and that locking means are provided on the casing that act in combination with the weight disks on their outer circumference.

2. A dumbbell with a dumbbell handle element and with at least one holder for removable fastening of one or more weight disks on one end of the dumbbell handle element, wherein electronic circuitry is provided for on the dumbbell handle element and/or on the at least one holder.

3. A dumbbell with a dumbbell handle element and with at least one holder for removable fastening of one or more weight disks on one end of the dumbbell handle element, wherein the at least one holder consists of a casing, the interior of which is open on a front side facing away from the dumbbell handle element for insertion and removal of the weight disks, and whereby locking means are provided on the casing that act in combination with the weight disks on their outer circumference, the locking means consist of at least one swiveling locking element which locks the weight disks accommodated in the interior in recesses with an edge area.

4. A dumbbell with a dumbbell handle element and with at least one holder for removable fastening of one or more weight disks on one end of the dumbbell handle element, wherein the at least one holder consists of a casing, the interior of which is open on a front side facing away from the dumbbell handle element for insertion and removal of the weight disks, whereby locking means are provided on the casing that act in combination with the weight disks on their outer circumference, locking means are provided on the casing that act radially upon the weight disks on their outer circumference, the locking means consist of at least one swiveling locking element, which locks the weight disks accommodated in the interior in recesses with an edge area.

5. A dumbbell with a dumbbell handle element and with at least one holder for removable fastening of one or more weight disks on at least one end of the dumbbell handle element, comprising at least one active or passive electric or electronic component in the dumbbell handle element and/or in the at least one holder, the electronic component acts in combination with an external anti-theft device.
