Definitions

  • the invention relates to a ski with toe bars.
  • a ski is e.g. known from DE-GM 74 12 359.
  • the well-known track is designed as a vertically standing flat metal piece fixed on one side of the ski, the lower edge of which forms a tracking edge running in the direction of travel, which projects downward beyond the ski sole.
  • Such an arrangement has the purpose of still safely guiding the ski even on hard slopes or on ice and slipping when driving across the slope on a hard surface. To prevent slopes or on ice.
  • the well-known fixed track is pressed under the weight of the skier into the snow surface, so that it digs deeper in soft snow than in hard snow or ice.
  • the guidance aid is particularly desirable on hard and icy slopes.
  • the object is achieved by the invention of creating a ski with track tracks, which becomes increasingly effective with increasingly difficult slopes.
  • the toe is designed as a spring-loaded track lever which can be pivoted about a bearing pin running perpendicular to the longitudinal direction of the ski and extends vertically from the bearing pin towards the ski tip and in its upper swivel position with its track edge projecting beyond the ski sole Front end is offset from the bearing pin to the front and down.
  • the touring according to the invention works differently in different snow conditions. Since, according to the invention, a pivoting lever that can be pivoted about its bearing pin is used as a track iron and the toggle lever with its protruding downward beyond the ski sole, the track edge of its front end is arranged at a distance below the bearing pin, a force moment acts on the toggle lever when driving, all the more is greater, the greater the driving resistance between the front end of the toe lever and the snow pad, and the harder the snow pad is.
  • the track edge of the front end of the track lever which extends beyond the ski sole and extends forward from the bearing pin in the direction of the ski tip parallel to the longitudinal direction of the ski, is also arranged at a distance from the bearing pin in the longitudinal direction of the ski, the track lever with its track edge under the moment of force acting on him with increasingly harder base increasingly pulled down into this, so that the effectiveness of the toggle is intended to be stronger with a harder slope.
  • a toe tip is formed with an angle of less than 180 °, preferably less than 90 °, from the track edge of the front end of the track lever which projects downward beyond the ski sole. If necessary, however, it is also possible to form one or more sharpened teeth in the manner of saw teeth on this track edge, preferably pointing forward in the upper swivel position of the track lever.
  • the spring which acts on the track lever, can optionally act on the track lever in such a way that it is pivoted into its lower pivot position under the spring force.
  • the part of the front end of the toggle lever projecting under the ski sole is preferably provided with a forward-pointing toe, edge part which is inclined at a flat angle to the longitudinal direction of the ski.
  • the spring counteracts the pivoting of the track lever from its upper swivel position downward against the track lever.
  • the upper pivot position of the track lever is its rest position, into which the track lever is pulled or pressed by the spring and in which it hardly protrudes beyond the ski sole with its guide edge.
  • an ever-increasing moment of force acts on the track edge, under which the track lever is pivoted against the force of the spring around the bearing bolt so that the track edge dips deeper and deeper into the snow and protrudes more and more over the ski sole.
  • this deflecting moment of force becomes so great that the track lever, the track edge of which is preferably sharpened, cuts into the ice plate.
  • the spring in which the "spring pulls or pushes the track lever in its upper rest position, depending on snow conditions, there may also be a need to relax the spring, so that the track lever is then only loaded by its own weight and otherwise is able to freely give in to the forces acting on it during travel.
  • the spring is therefore in the form of Tension spring formed, which is hooked with its rear end facing away from the toggle lever into a tensioning slide which can be moved forward in the longitudinal direction of the ski, but can be locked against its forward displacement on a manually actuated release mechanism. Therefore, if the cocking slide is in its locking position, the spring is cocked.
  • the cocking slide can move forward under the tension of the spring, so that the spring is relaxed. If necessary, releasably lockable intermediate positions of the cocking slide for adjusting the respective spring force of the tension spring can also be realized.
  • the ski according to the invention with a toe lever, this can be arranged in the transverse center of the ski and protrude downward through a recess in the ski and beyond the ski sole.
  • a toggle of the type described is arranged on each side of the ski.
  • the toggle levers are preferably articulated to an expansion linkage by means of their bearing bolts, so that they are fastened to the ski so that they can be spread out to the side.
  • a locking device which can be actuated by the ski boot inserted into the ski binding, engages the spreading linkage, by means of which the spreading linkage is locked for the journey in a position in which the toggle levers lie laterally on the ski and with their toe edges running parallel to the longitudinal direction of the ski, but through which by the When the ski boot is released from the ski binding, the expansion linkage is released for the lateral spreading of the toggle levers so that they then run obliquely to the longitudinal direction of the ski and take over their braking function.
  • the automatic usspreizen A of the track lever can be carried out under the train of them acting on the spring. If necessary, however, an additional spring or lever mechanism can also be used, as is known per se for conventional ski brakes.
  • the ski 10 according to FIG. 1 has a track iron 11, which essentially consists of a track lever 12 designed as a flat metal piece, a bearing pin 13 and a tension spring 14.
  • the track lever 12 is designed as an L-shaped angle lever, the shorter L-leg of which is plate-shaped. With this plate-shaped part, the track lever 12 engages through a recess 15 which is recessed in the cross center of the ski 10.
  • the longer leg of the L-shaped track lever 12 runs above the ski and is pivotally mounted in the bearing pin 13.
  • the plate-shaped part of the toggle lever lies behind the bearing pin 13 in the direction of travel 16.
  • the bearing pin 13 is mounted in bearing blocks 17 above the ski.
  • the part of the toggle lever 12 lying in front of the bearing pin in the direction of travel is pressed downward in the direction of the surface 18 of the ski by the tension spring 14 designed as a leaf spring.
  • the lowest limit of the toe lever 12 extends slightly obliquely to the ski sole 19, in such a way that it protrudes slightly further beyond the ski sole 19 at its front end than at the rear end.
  • This lower edge is somewhat sharpened and serves as a tracking edge 20.
  • At the foremost end of the tracking lever 12 there is also a sharpened cutting edge 21 at approximately a right angle to the tracking edge 20.
  • the tracking tip 22 is in the upper rest position of Track lever 12, in which the tension spring 14 presses the rear end of the track lever 12 all the way onto the ski surface 18, about 2 mm downward beyond the ski sole 19.
  • the ski runs on solid snow or ice while driving, a large force acts on the tip 22 of the track, which causes the track lever 12 with its track edge 20 against the force of the tension spring 14 around the bearing pin 13 downward is pivoted, whereby the tip of the track 22 penetrates deeper into the snow or ice surface and cuts through it.
  • the toe lever 12 can be pivoted until it rests on the ski surface 18 with a stop bolt 23 attached to it above the ski 10.
  • the lever ratios and the spring force are selected in this embodiment so that the toe lever 12 is in the rest position when driving over powder snow or over only lightly crested snow, but that it is more deflected in heavily crunched or firmer snow and that it is driven over ice is pivoted into the lower tracking position. Thanks to this self-adjustment, optimum tracking is achieved in every snow condition.
  • FIG. 2 A further embodiment of a ski 10 with track iron 11 can be seen from FIG. 2.
  • the track iron 11 in this case has two track levers 12 which are pivotably attached to the side faces 24 of the ski 10. So that when the two skis run parallel to one another with their adjacent toggle levers 12, a semicircular spacer 25 is attached to the inner side surface of the ski 10 in the direction of travel 16 in front of and behind the toggle lever 12 attached there, somewhat from the side surface 24 projects further outwards than the track lever 12.
  • Each track lever 12 is in turn pivotally mounted on a bearing pin 13 which is mounted in a bearing block 17 in a position so that it is perpendicular to the longitudinal direction 16 of the ski and parallel to the ski plane.
  • the geometric arrangement and the force relationships are corresponding to those as described in the embodiment according to FIG. 1.
  • the tension spring 14 is now designed as a tension spring and the upper rest position of the track lever 12 is determined by a second stop pin 26 thereon.
  • the S p urzhoukante 20 and the cutting edge 21 form in the embodiment of Fig. 2 an obtuse angle to form an obtuse track tip 22.
  • the toggle levers 12 are arranged on both sides of the ski binding (not shown) and are articulated by means of their bearing bolts 13 to a spreader linkage comprising two spreading levers 27 which are at an angle, the apex of which is in the center of the ski behind the bearing bolts 13 the toggle lever lies on the ski surface 18.
  • the spreading levers 27 are each pivotably pivoted about a pivot pin 28 which is fixed to the ski and is perpendicular to the ski surface 18 and which is arranged in the central region of the spreading lever 27.
  • the track levers 12 are arranged close to the side faces 24 and extend parallel to the longitudinal direction 16 of the ski, so that in this position they act as guides.
  • the spreading levers 27 are held in this position by a locking device 29.
  • This has a shoe plate 30, a lever actuation tab 31 and a connecting plate 32 connecting these two parts on.
  • the shoe plate 30 is pivotally mounted on its front edge 33 in a ski-like manner and is pivotally connected at its rear edge to the connecting plate 32, which in turn is pivotally connected to the actuating tab 31, so that the locking device 29 is designed as a hinge-like link plate chain.
  • the contact force 35 no longer acts on the shoe plate 30, it lifts off the ski surface 18 due to the force of the springs 34, which leads to a displacement of the holding pin 36 in the direction of travel 16.
  • the spreading levers 27 are no longer held in their position, but are pivoted about the pivot bolts 28 under the force of the tension springs 14 acting on them via the locking levers 12 together with the track levers 12 articulated on them, as a result of which the 'track levers 12 spread apart laterally from the ski sides 24 are and get into a position transverse to the direction of travel 16, in which position they act as a ski brake.
  • the .track levers with the tip of the springs 14 protrude only a few millimeters beyond the lower ski surface 19 under the tension of the springs 14. From this position, they can swivel downwards until their stop tabs 23 on the ski top 18 stop. However, if the spreading levers 27 are released by the locking device 29 and therefore the track levers 12 are spread apart under the tension of the springs 14, their stop tabs 23 are released from the ski body 10, so that the track levers 12 after the tension springs 14 are released by the spreading apart Can pivot pivot lever 27 further down.
  • the embodiment from FIG. 4 corresponds to that from FIG. 3.
  • the spreading levers 27 are not articulated on the ski body 10 itself via separate pivot bolts 28, but rather in the apex of the angle which they jointly form by means of the holding pin 36 the locking device 29 pivotally connected to each other.
  • the spreading levers 27 are spread apart not only by means of the tension springs 14 of the track levers 12, but also by means of the springs 34 of the locking device 29.
  • tension springs 14 of the track levers 12 in the embodiment from FIG. 4 are suspended with their rear ends in a tension slide 38.
  • the cocking slide 38 is mounted in a guide 39 in which it can be pushed back and forth in the longitudinal direction 16 of the ski. If the slide 38 is pushed completely to the rear against the direction of travel 16, the tension spring 14 is maximally tensioned and performs its function, as is explained in more detail in particular with reference to the embodiment according to FIG. 1. In this
  • the tensioned position of the slide 38 is held by a release mechanism 37, which has a pawl 40 connected to the slide 38, which is held by a pawl lock 41. Perr- by a blow to the S latch 40, it will be unlocked, whereby the spool 38 is released and thus the tension spring is relaxed 14, whereby the knuckle arm 12 due to its own weight about the bearing pin 13 rotate it downwards and deep with their track guide edges 20 in the Can cut into the surface.
  • FIGS. 5 and 6 corresponds in basic construction to that of Figure 2.
  • the knuckle arm 12 is formed relatively short as an angle lever, the NEN egg between their trail edge 20 and its cutting edge 21, forming the track tip 22 'acute Form an angle.
  • the normal driving position is shown in Fig. 5. If the track levers 12 hit a fixed obstacle, such as a stone, in this position of their track tip 22, they can pivot due to the resistance acting on them into the position shown in FIG. 6, in which they are at a distance behind theirs with their track tip 22 Bearing bolts 13 are arranged so that they can pivot further against the force of the spring 14 on the obstacle and can therefore slide over the obstacle.
  • a fixed obstacle such as a stone
  • the track levers 12 are not pressed into the upper pivot position by the spring 14 acting on them, as in the embodiments from FIGS. 1 to 6, but rather into the lower pivot position. Its track edge and its cut edge 21 form an obtuse angle, forming the track tip 22, so that its cut edge 21 is inclined points forward. If, therefore, the toggle levers 12 hit a solid obstacle, for example a stone, with their cut edges 21, they will be pivoted against this force against the force of the spring 14, preferably shortly before the safety device of the ski binding opens that they can slide over the obstacle.
  • a solid obstacle for example a stone
  • a measure (not shown) can be provided in all embodiments, by means of which the toggle levers 12 can be detachably locked in an upper swivel position, in which their track edge does not protrude beyond the ski sole, if additional guidance of the ski is provided in appropriate snow and terrain conditions is not necessary or appropriate.
  • the toggle levers according to the invention can be designed as a structural unit that is independent of the ski binding.
