Definitions

  • the invention relates to a sports device for sliding on the respective surface according to the preamble of claim 1, in particular a winter sports device.
  • the typical case of a winter sports device with two skids that can be moved independently of one another is the pair of skis, in which each ski is firmly connected to a foot via a binding. From this, for example, the mono-ski equipped with only one skid was derived, in which both legs are attached to only one skid, usually by means of an intermediate plate.
  • Another representative of a winter sports device with only one skid is the so-called snowboard, in which, however - in contrast to skis - the user does not stand in the direction of travel, but with one leg across and with the other at an angle to the direction of travel.
  • Austrian patent 372 052 shows a winter sports device of the same type with only one base plate, in which the skids with the connecting element on the one hand and the connecting element with the standing plate on the other side are operatively connected at the front and rear by only one swivel axis. The edging movement is passed on via a gear transmission.
  • a sports device according to the invention can therefore be used in addition to winter sports with corresponding modifications with regard to weight, load and fastening devices for the driver for these water sports.
  • the user can stand on the winter sports equipment in any desired direction and freely choose the type of connection to the base plate or base plates.
  • the base plate can also be used as a seat.
  • the edging movement is passed on from the skids to the base plate or vice versa, in that the swivel axes between the individual parts connected to one another either do not run parallel to the longitudinal direction of the winter sports equipment, but rather are inclined to this, or - in parallel arrangement - supporting parallelogram levers available.
  • This oblique position can lie obliquely to the direction of travel in the horizontal plane, that is to say parallel to the plane of the sliding surfaces in the rest position, as a result of which a different longitudinal offset of the skids from one another takes place when edging in the two different directions.
  • an inclined position of the swivel axes in a plane perpendicular to the plane of the sliding surfaces and running in the longitudinal direction is expedient, since the longitudinal offset of the skids is identical to one another in both directions.
  • the number of sliding runners articulated parallel to one another on the connecting link is arbitrary.
  • connecting links are also variable: As a rule, two connecting links, that is to say crossbars, are used in the longitudinal direction one behind the other, on or between which one or two base plates are fastened. If the dimensions of the bearing axles of the components which are movable relative to one another are of sufficient dimension, that is to say, a single transverse bracket, which is then relatively large in the longitudinal direction, may also be sufficient. A disadvantage of using only such a crossbar, however, is the difficult implementation of the lowest possible position of the base plate, which is necessary for the winter sports device to behave well.
  • Another variant consists in using two connecting units, each of which comprises at least one crossbar and, at a short axial distance from it, a further articulated connection of the pivoting lever to the skid.
  • Crossbar and articulated connection are arranged off-center and opposite each other to the longitudinal center of the skids, which facilitates the transmission of power from the base plate to the skids.
  • the articulated connection which roughly corresponds to the tines of one of the crossbars, can also be completed to form a second crossbar per connection unit.
  • Another variant are two cross brackets that only have a single, common longitudinal center plate.
  • the pivot lever can be functionally combined with the base plate, so that the base plate can thus be arranged directly on the connecting members, for example the crossbars.
  • the length of the tines of the crossbar depends above all on the dimensioning of the skids in the transverse direction, since the length of the tines must ensure that the skids are edged up to approximately the vertical position one above the other and thus have a free length of half the width of the skids must if the attachment to the skids is in the middle, or a little more if the attachment to the skids is off-center.
  • the skids - against the load caused by vertically occurring forces - in the middle area i.e. the area under the base plate and between the attachment points of the connecting links (i.e. the crossbar) on the skids, more elastic and softer are trained as in the field of Fastening the crossbar.
  • skid and crossbar can be guided in a longitudinally displaceable manner, with a predetermined rest position being resumed by means of spring preload when the device is not loaded.
  • the base plates are generally fastened between the front and rear crossbars via swivel levers.
  • the swivel levers if available as individual parts, have at least one leg that projects horizontally in the neutral position and projects outwards from the swivel axis to the crossbar, which is used as a hinge part for the front or rear end of a Stand plate serves. This transverse leg should be arranged as low as possible to enable the lowest possible position of the base plate.
  • the transverse leg will therefore be arranged by a vertically projecting leg only so far above the skid that when fully edging, i.e. arrangement of e.g. three skids one above the other, the horizontal leg of the upper intermediate piece just runs over the upper surface of the upper skid, and a collision between the skid and the base plate is avoided.
  • This height distance between the transverse leg and the upper surface of the skid can be the smaller, the farther outside the pivot axis between the pivot lever on the one hand and the crossbar on the other hand on the crossbar 1 1.
  • the user can stand with one shoe each on one of the base plates in the direction of travel.
  • a vertical offset of the base plates to each other and thus - transferred to the sliding runners - an upward movement of the sliding runners is achieved, the sliding surfaces of which are still parallel to one another, but offset in the longitudinal direction and additionally no longer lie in one plane but in spaced parallel planes to each other.
  • Another solution according to the invention requires only one base plate, regardless of the number of skids.
  • the use then resembles a conventional snowboard in terms of attachment and position of the driver, but the force required for edging the winter sports equipment is considerably less and the edging can also be initiated much more gently. Overall, this results in a significantly better driving behavior.
  • the driving behavior is particularly positively influenced if the base plate of the winter sports device is further away from the mountain than the mountain ski when the winter sports device is edged, so that the load is more heavily on the valley ski.
  • the base plate is placed lower than the upper edge of the crossbar, for example, with two crossbars, a fastening between the crossbars at a lower level, or with only one crossbar a stepped base plate, so that to the left and right of the crossbar, seen in the direction of travel in front of it and behind it, there is space for one foot of the user.
  • the base plate In order to enable the base plate to move towards the valley-side skid during this upward edging, the base plate is fastened to the connecting members, i.e. the crossbars, in such a way that a swiveling movement takes place between the baseplate and the crossbar when it is upright, looking in the direction of the vehicle, but not around a fixed one , centered with respect to the crossbar, takes place, but by at least two different or by the edging movement
  • crossbars consist of a closed hollow profile, at least in the area of their tines, and the swivel axes of the crossbar with respect to the skids on the one hand and the swivel levers on the other hand are realized with the aid of disks which are relatively large compared to their axial length, that fit into the hollow profile of the crossbar or can be stored in it.

  • two different embodiments of the connection of the base plate (7) or the pivot lever (8) with the crossbars (4) are shown on the left and right side.
  • the sliding skid 2 should be able to bend up and down, especially in its central length region 201, that is to say in the region between the bearing blocks 40 for the cross brackets 4, in accordance with the vertical loads occurring and the shape of the subsurface.
  • the aim is always to deflect the base plate (7) or the swivel lever (8) from the horizontal central position to effect the so-called upward edging, which also results in a corresponding upward edging of the skids (2) in order to ensure good edge grip of the skids (2) to achieve an inclined plane, as shown in Figure 3.

  • FIG. 5 also shows a detailed solution in which, instead of the intermediate lever (13), the length compensation is solved directly by the design of the upper swivel axis (5): While the crossbar (4) in the manner described above via inclined swivel axes (6) its lower free ends in the bearing blocks (40) of the skids (2) is mounted, the upper pivot axes (5) are realized by bolts (145) which go parallel to the lower pivot axis (6) through the crossbar (4).
