(16) FIG. 1 illustrates the training device in assembled condition, comprising four cross-members 10, wherein a support column 20 is allocated at the end of each cross-member. The cross-member 10 is connected with the support column 20 by means of the pin 30. The pin 30 is connected with the support column 20 by means of the snap-fit.

(17) FIGS. 2 to 4 illustrate the cylinder-shaped support column 20. The support column at its upper part comprises a cross-wall 21 with a cross-wall opening 22 in the centre thereof, that has a cylindrical protrusion towards the centre and along the longitudinal axis X of the support column 20. In addition, the end circumference 14 of the cylindrical protrusion 12 of the cross-member 10 can be based on the annular step 24 formed on the cylindrical protrusion 23.

(18) FIGS. 5 and 6 illustrate the pin 30 for the attachment of the cross-member 10 to the support column 20. The pin 30 comprises a core 32 with a head of the pin at the one end and a free end at the other end. At the free end of the core are sequentially arranged two annular snap-fitting beads shaped as cut cones with ends narrowed towards the free end of the pin. When the training device is in assembled condition, the snap-fitting beads are inserted in the cylindrical protrusion 23 of the opening of the support column 20. In order to facilitate the assembly and disassembly, the longitudinal cut 35, that extends from the free end 33 of the pin 30 through the annular snap-fitting beads 34 and slightly forward towards the head 31 of the pin 30, is formed in the core 32 of the pin 30.

The end opening 11, similarly to the end opening 22 of the support column 20, comprises a cylindrical protrusion 12 with an annular step 13. The above-mentioned cylindrical protrusion is formed so to mate with the cylindrical protrusion 23 of the support column, in particular, so that the end circumference 14 of the cross-member 10 cylindrical protrusion can be based on the annular step 24 of the cylindrical protrusion 23 of the support column 20. The cylindrical protrusion 12 of the cross-member 10 comprises an annular step 13 that is formed so the head 31 of the pin 30 or the end circumference 14 of the cylindrical protrusion 12 of the cross-member 10, in case, when two ends of the cross-elements 10 are allocated on the same support column 20 for mating, can be based thereon. Moreover, on the one side of the cross-member at its both ends at the area of the end opening 11 an annular groove, coaxial with the opening 11 and the cylindrical protrusion 12 thereof, if formed. The groove is formed in order to receive the upper part of the support column 20. FIG. 11 illustrates the groove 14 of the cross-member 10 that additionally comprises three ribs 16 allocated along the circumference. The ribs provide the support for the upper part of the support column 20 or the part thereof that is inserted into the cross-member 10, thus restricting the radial movement of the support column 20 while in mate with the cross-member 10.
