EXAMPLES
Example 1
[0203] In FIG. 1 an example of a composite rotating toy body according to the invention is shown. This consists of a cylindrical swing body (S) and cylindrical disc-shaped side caps (K1) with an outer edge (R1) and (K2) with an outer edge (R2). The cylindrical swing body(S) is made of polyoxymethylene (POM). The swing ring (S) or the outer shell (M) of the swing ring (S) shows an outer diameter of 3.5 cm and width of 1.0 cm. The outer shell (M) is printed with 10 motifs in two dimensions. Into the cylindrical outer shell (M) of the swing body (S) a centred ball bearing (L) is inserted, which is made of polyoxymethylene (POM) and the balls of the ball bearing (L) are made of stainless steel. The first central recess (A1) has a diameter of 1.6 cm. The cylindrical centred ball bearing (L) has an outer diameter of 1.6 cm, a width of 0.8 cm and a cylindrical second central recess (A2) with a diameter of 1.0 cm. The assembled rotatable play body has on the one hand the disc-shaped side cap (K1) as a round disc with a plane printable circular outer face (F1) and on the other hand the plane printable circular disc-shaped side cap (K2). The cylindrical disc-shaped side caps are also made of polyoxymethylene (POM) and each have an outer diameter of 3.5 cm and a width of 1 mm. The assembled disc-shaped side caps (K1) and (K2) are arranged parallel to each other with a distance of 1.2 cm between the two inner faces (I1) and (I2). The disc-shaped side caps (K1) and (K2) each have a two-stage extension (P1) and (P2), each with a length of 0.5 cm, centrally arranged on the inner faces (I1) and (I2) of the disc-shaped side caps (K1) and (K2). The first stage of the two-stage process (P1) and (P2) has a length of 2.0 mm and a diameter of 1.2 cm. The second stage of the two-stage process (P1) and (P2) is 3.0 mm long and 1.0 cm in diameter. Thus, the first centred extension (P1) engages the second central recess (A2) of the centred ball bearing (L) to a depth of 3.0 mm and the second centred extension (P2) engages the second central recess (A2) of the centred ball bearing to a depth of 3.0 mm without the centred extensions (P1) and (P2) interlocking.
[0204] The assembly of the rotatable play body is carried out in such a way that first the first disc-shaped side cap (K1) is assembled with the swing body (S) by engaging the first centred extension (P1) of the disc-shaped side cap (K1) in the second centred recess (A2) of the centred ball bearing (L). The second disc-shaped side cap (K2) is then assembled with the previously assembled swing body (S) and the first disc-shaped side cap (K1) by form-closed engaging the second centred extension (P2) in the second central recess (A2) of the centred ball bearing (L) on the opposite side. This provides a rotatable play body according to the invention, in which the distance of the swing body (S) to the inner faces (I1) and (I2) of the disc-shaped side caps (K1) and (K2) is 0.1 mm respectively, so that the swing body (S) between the two disc-shaped side caps (K1) and (K2) is freely rotatable, so that it can be taken in the left hand and with the right hand the swing body (S) is rotated, which after 10 seconds still rotates freely at a speed of 2 rotations per second.
[0205] By pressing with a pressure of approx. 22N on the outer edge (R1) of the side cap (K1) and at opposite position on the outer edge (R2) of the side cap (K2), the side caps (K1) and (K2) can be pressed against the swing body (S) in such a way that the swing body (S) can no longer rotate and its position and thus that of the motifs on the outer shell (M) is fixed.
