DUMBBELL
First Claim
1. A dumbbell with weight disks, where the number of weight disks on the dumbbell is selectable, and the weight disks may be accommodated standing upright in two sets in a base assembly, the weight disks having through-going openings which are located along a straight line with the weight disks standing in the base assembly, and the weight disks have mutually cooperating connecting means which are disposed, in an axial direction of the dumbbell, to interconnect neighbouring weight disks, but in a radial direction to permit separation of a weight disk from a neighbouring weight disk, wherein the weight disks are in the form of substantially planar disks with a substantially circular unbroken peripheral edge and with the openings located centrally, that all connecting means have a longitudinal centre line which coincides with a diameter line for the weight disk, and with the permitted, radial displacement between two neighbouring weight disks.

Abstract
A dumbbell with a selectable number of weight disks includes a handle with pins projectable in opposing directions, a base assembly for accommodating two sets of weight disks standing on edge and provided with openings. The projection lengths of the pins are stepwise selectable in order to permit selection of the number of weight disks supported on the handle. Neighbouring weight disks have mutually engaging connecting arrangements which axially interconnect the weight disks but which permit radial separation. The weight disks are planar with a circular, unbroken peripheral edge and with the openings located centrally. All connecting arrangements have a longitudinal centre line which coincides with a diameter line for the weight disks and with the permitted radial displacement direction between two neighbouring weight disks.

4. The dumbbell as claimed in, wherein the connecting means extend along substantially the whole of the diameter of the weight disk.
-
5. The dumbbell as claimed in, wherein the weight disk is manufactured from at least one first material constituting a core in the weight disk and one second material, constituting a surface layer for the weight disk;
- and that the core also extends over that region of the weight disk where the weight disk displays its connecting means.

7. The dumbbell as claimed in, wherein the undercut depression has a substantially dovetail-shaped cross section.
-
8. The dumbbell as claimed in, wherein the weight disk has means for its positioning about its centre axis in relation to the base assembly;
- and that a plurality of weight disks in their thus established positions have their connecting means in engagement with one another; and
that the centre lines of the connecting means are substantially vertical when the base assembly stands on a horizontal substrate.
- and that a plurality of weight disks in their thus established positions have their connecting means in engagement with one another; and
-
9. The dumbbell as claimed in, wherein all weight disks in a base assembly have the same configuration and that they are randomly interchangeable in position in the base assembly as well as being separate and discrete from one another.
