  • the front section 4a of the stiffening device 4 moves to the left, the front section 4a shifts the latter via the nuts 1061a, 1061b of the driving bolts 1059a, 1059b to the left.
  • the driver pins 1059a, 1059b in turn take the driver 1060 with their reinforced end sections 1059c, 1059d to the left with.
  • the dimensions of the gaps 1055a, 1055b remain unchanged, whereas the coil spring is compressed between the disc 1044 and the moving driver 1060, which results in a change in the curvature height of the ski 1 according to FIG. 3.
  • the fourth embodiment of a spring system 1105 according to FIG. 31 results from a combination of the embodiments according to FIGS. 28 and 30, but this results in an action which differs from the embodiment according to FIGS. 28 and 30.
  • an elongated recess 1168 is formed in the nose 1151 of the rear section 4b, into which a spring 1166 is inserted.
  • the front section 4a of the stiffening device 4 also has a separate recess 1169, on whose end facing the rear section 4b of the stiffening device 4 a driver block 1167 is mounted.
  • the elongated recess 1168 of the rear section 4b of the stiffening device 4 has a separate section 1170, in which the driver block 1167 is freely movable.
  • a spring 1165a and a spring 1165b bear directly against both the front section 4a and the rear section 4b of the stiffening device 4.
  • the two springs 1165a, 1165b are guided through the shafts of the driving pins 1159a, 1159b and rest on the rear end sections 1159c, 1159d, which are made stronger than the shaft diameter of the driving pins 1159a / 1159b.
  • the design of the head bores 1146a, 1146b with the nuts 1161a, 1161b guided in them, the driving bolts 1159a, 1159b and the blind bores 1158a, 1158b corresponds to what has already been described.
  • the two springs 1165a, 1165b are first compressed between the front section 4a and the rear section 4b of the stiffening device 4.
  • the driver block 1167 moves in the Recess 1170 to the right.
  • the coil spring 1166 has no effect. If the gap 1155 is bridged between the elastic block 1152 and the end face 1151a of the nose 1151, the elastic block 1152 also becomes effective according to its characteristic curve, thus together with the characteristic curves of the coil springs 1165a, 1165b the required favorable characteristic of the spring system 1105 for this direction of movement achieved. This results in a change in the curvature of the ski 1 according to FIG. 2.
  • the invention is not limited to the illustrated and described embodiments. Further variants are possible without leaving the scope of the invention.
  • combinations of the control mechanisms according to FIGS. 5 to 27 with the spring systems according to FIGS. 28 to 31 would be conceivable.
  • a reverse assignment of the spring system parts to the two sections 4a, 4b and an arrangement of the control mechanism in the area of the heel holder would be possible.
  • a bolt with a securing device e.g. by means of a cross pin.
  • the bolts could also be fastened in the stiffener itself, e.g. injected, pressed or snapped.
  • the head can be formed in one piece with bolts.
  • a further embodiment according to the invention is characterized in that the control mechanism is equipped with a device for displaying the degree of stiffening or the bulge height of the gliding device, with either a mark on the base body and markings on the rotatable component or on the handle, preferably with dimensions, being provided .
  • the arrangement of the mark can also be interchanged with that of the markings.
  • control mechanism 6 and stiffening device 4 it is also within the scope of the invention to mount a combination of control mechanism 6 and stiffening device 4 in an expedient configuration and arrangement on the top of a snowboard.
