  • a threaded sleeve 123 ' a corresponding threaded portion for the adjusting spindle 42' may also be formed directly in the wall parts of the housing 14.
  • the axially adjustable adjusting spindle 42 ' determines the respective spreading or wedge effect of the wedge element 116'.
  • this adjustment device 2 can be structurally relatively solid and yet inexpensive to run. Another advantage is that this adjustment device 2 can be made relatively compact and yet the respective required Stellweiten or tensile force changes against the tension elements 5, 6 can be generated.
  • adjusting spindles 42-42 in conjunction with threaded sleeves 123-123
  • at least one toggle lever arrangement as actuating or adjusting means for the slide elements 117, 118.
  • the slider members 117, 118 may be hingedly connected to the distal ends of the toggle lever, whereas the middle hinge or knee joint cooperates with an actuator, such as an adjusting spindle or eccentric lever assembly, to vary the spreading angle between the lever members of the toggle lever and thus to influence the pulling action of the tension elements 5, 6.
  • an actuator such as an adjusting spindle or eccentric lever assembly
  • Fig. 26 is the operation of the adjustment device 2 comprising at least one presetting device 10, 10 'and further illustrates a celebrityatinstellvoroplasty 11 schematically.
  • a presetting device 10 ' is formed, with which production-related tolerances can be compensated or reduced.
  • the bending stiffness or the so-called “Flex behavior" of the respective sliding device are calibrated or adjusted to a specific output value.
  • An adjustment range of this presetting device 10 ' can be, for example, approximately +/- 30 N depending on the respective production tolerances.
  • this presetting device 10 'produced sliding devices can be calibrated or adjusted relatively accurately to a basic setting value of, for example, 50 kg. This calibration or adaptation preferably takes place at the factory or on the part of the dealer of corresponding sliding devices.
  • a presetting device 10 is in any case formed with which the respective bending behavior can be adapted to the respective desired setting values.
  • the respective weight of the corresponding user is stated as the setting parameter.
  • a setting can be made within a value range of 20 kg, in particular from 50 kg to 70 kg. Of course, other adjustment ranges or bandwidths are selectable.
  • the travel required for the presetting device 10 is approximately 10 mm with respect to the tension elements 5, 6 (see Fig. 25 ).
  • the adjusting device 2 comprises the additional setting device 11, with which the values preset via the presetting device 10, in particular the bending stiffness values of the board-like gliding device abruptly and preferably without tools can be raised to a higher value and subsequently lowered again in a simple manner.
  • This additional setting device 11, which can also be referred to as “overdrive means”, allows, for example, a value change of +/- 10 kg. That is, with a set value of 55 kg, it is possible to increment to approximately 65 kg by means of the adjuster 11 in a quick and easy manner.
  • a provision for the preset value of the preset device 10 of, for example, 55 kg is made possible in a simple and rapid manner.
  • a required for the additional adjustment device 11 travel for the tension elements 5, 6 is only about 5 mm.
  • a travel distance to be applied by the presetting device 10 is only about 10 mm, in order thereby to have a setting range of 20 kg relative to the body weight to reach a user. These ranges can be achieved properly with the specified adjustment 2.
  • the values set by means of the presetting device 10 can be quickly and effortlessly raised by a specific value and lowered again in a similarly rapid and abrupt manner by actuation of the auxiliary setting device 11.
  • a board-type sliding device equipped with such an adjusting device 2 can thus better cope with a plurality of users and also a plurality of different environmental conditions, types of use, individual desired ideas and the like.
  • a relatively high and relatively exactly reproducible quality level can be ensured with the board-type sliding devices equipped therewith.
