Definitions

  • the invention relates to a ski bob, consisting essentially of a frame with a seat on which a steering column having a handlebar at the end is rotatably attached, via which a front ski attached to it can be actuated, and with a rear ski attached to the frame, the respective connection being slight Allows swiveling movements of the front and rear skis around an axis vertical to the longitudinal axis of the ski.
  • Skibobs are steerable single-track slope descent devices that are operated while sitting, whereby respective steering corrections - similar to a bicycle - are brought about by turning the handlebars. Foot skis that the ski bobber has buckled on serve as support and further steering corrections.
  • the skibobs known according to the prior art have a steering column with a handlebar to which the skibob frame with the seat is attached via a swivel joint.
  • the underside of the frame is formed by the rear ski, the tip of which is extended to the point of articulation on the steering column.
  • the front ski can be mounted in a height-adjustable manner in the steering column via a resilient connection, whereas the rear ski is articulated more rigidly and at most has a coarser spring damping.
  • the front ski attached to the steering column as well as the rear ski attached to the frame can perform smaller swiveling movements via a tilting bearing in which rubber bumpers or other spring elements serve as reset elements on both sides of the rocker arm.
  • Embodiments are also known in which the frame strut connected to the rear ski is connected to the rest of the frame below the seat by means of a joint, so that the rear ski can be folded "up” after loosening the rear ski attached to the steering column.
  • This folding down reduces the length of the ski bob, but at the expense of height, so that the ski bob is still bulky and difficult to handle when folded.
  • the space requirement of the ski bob, even when folded, is still so large that an additional seat is usually required for storage.
  • handling such a ski bob when folding is cumbersome and time-consuming.
  • the folding mechanism should be structurally simple.
  • the ski bob according to claim 1 which is characterized according to the invention in that the frame consists of several articulated struts which can be guided against one another by shear movements.
  • the frame consists of several articulated struts which can be guided against one another by shear movements.
  • Folding down frame parts minimizes both the length and the height of the ski bob by shearing movements, whereby the folding movement to an even more compact object can be completed, if necessary, by increased swiveling movements of the front and rear skis about an axis vertical to the longitudinal axis of the ski.
  • the collapsed ski bob then has a significantly reduced length and an even more reduced folding height, which makes it possible, for example, to use the ski insertion shafts on the outside of small gondolas, since the low folding height remains below the permissible "overhang”. Elaborate screwing or dismantling work of the ski bob can be avoided before transportation.
  • the folded ski bob is a one-piece piece that is easy to transport due to the low folding volume that has been achieved.
  • the steering column is preferably rotatably arranged in a sleeve forming part of the frame (similar to a fork in a bicycle), two frame struts being articulated on this sleeve, one of which is connected at the end via a joint connection to a thrust unit along or parallel to the longitudinal axis the other frame strut is displaceable and a further frame strut connected to the rear ski is articulated on this thrust unit.
  • a sleeve encompassing the other frame strut is preferably selected as the thrust unit, on the outer jacket of which the remaining frame struts are articulated.
  • the relevant slidable sleeve is connected to all frame struts, the two frame struts articulated to the handlebar sleeve creating a triangle with the handlebar sleeve, which height can be changed by moving the sleeve.
  • the frame strut connected to the rear ski is pivoted forward by moving the sleeve.
  • the sleeve can preferably be locked against longitudinal displacements with a tension lock, in particular a quick-action lock on the frame strut.
  • the said displaceable sleeve is attached via a hinge at the end to the upper frame strut, which is connected to the sleeve receiving the steering column in its upper region.
  • the lower frame strut which is connected to the sleeve receiving the steering column in its lower region and along which the pushing unit or sliding sleeve can be moved, is equipped at its other free end with a seat, preferably a bench, which can be adjusted via a quick-release fastener.
  • Concerning quick-release fasteners are known in the prior art, in particular for bicycles.
  • the frame strut connected to the rear ski and the aforementioned lower frame strut are connected to a spring element via a cross strut, the end-side connection points of the cross strut being each designed as a joint.
  • the cross strut serves as a swivel support. If you move the thrust unit, which is designed as a sleeve, along the lower frame strut in the direction of the seat attachment, the cross strut supports the pivoting movement of the frame strut connected to the rear ski to the front.
  • the thrust width of the thrust unit is preferably limited in the clamping direction by a stop, in the simplest case by a bead provided on the lower frame strut or a ring fastened there. This bead or ring makes it easier to find the skiing position of the ski bob again.
  • the actuation of the quick release then serves only for the purpose that the sleeve in question is locked, so that displacements of this sleeve on the frame strut in question are excluded in hilly terrain.
  • the front and / or the rear ski are preferably secured or unlocked by means of releasable catches relative to the steering column or the rear frame strut against pivoting movements about an axis vertical to the longitudinal axis of the ski.
  • the safety lock is used to be able to fold down the front or rear skis in order to maintain the most compact shape of the ski bob when folded. During the journey, these swiveling movements are excluded by appropriate locks, the permissible minimal swiveling movements relative to the frame column and / or the rear frame struts still being retained.
  • This suspension system is generally known from the prior art.
  • Fig. 4 the Skibob in the folded state.
  • An essential part of the ski bob is the metal frame, which consists of the sleeve 10 for receiving the steering column 11, an upper frame strut 12, a lower frame strut 13 and a rear frame strut 14.
  • the frame struts 12 and 13 are each fastened to the sleeve 10 via joints 15 and 16, which allow pivoting movements relative to the sleeve in the sheet plane shown in FIG. 1.
  • the upper frame strut 12 is also movably connected via a further joint 17 to a sleeve 18 which is arranged displaceably in the direction of arrow 19 on the lower frame strut. This sleeve can be locked on the lower frame strut 13 via a quick-release fastener 20.
  • a seat 26 is adjustable in height, expediently fastened by means of a corresponding quick-release fastener.
  • a relevant seat attachment is generally known for bicycles.
  • the steering column 11 has a handlebar 27 at its upper end and is connected to the front ski 28 at its lower end.
  • the rear ski 29 is attached to the lower end of the rear frame strut 14.
  • detents 30 and 31 are provided on the connection between the front ski 28 and the rear ski 29, which enable unlocking to a possible swiveling movement of the mentioned skis. In the driving state shown in Fig. 1, these detents 30 and 31 are blocked, so that the front and rear skis 28 and 29 only slight pivoting movements, which are possible via a two-armed rocker arm by spring elements, are permitted. In this respect, too, reference can be made to embodiments known from the prior art.
  • Fig. 4 shows the Skibob in a folded state, in which the same parts are provided with the same reference numerals. The following activities must be carried out to fold the ski bob:
  • the quick-release fastener 20 is released, after which the sleeve 18 can be moved in the direction of the arrow 19 along the lower frame strut 13.
  • the locks 30 and 31 are released so that the front and rear skis over the intermediate positions shown in FIGS. 2 and 3 can be pivoted into the folding position shown in FIG. 4.
  • the rear frame strut 14 moves along the arrow 32, whereas the sleeve 10 with the steering column 11 is moved in the direction of the arrow 33.
  • the resulting shear movement of the frame parts 10, 12, 13 and 14 and the cross strut 22 leads to a corresponding movement of these parts towards one another in an almost parallel position, the rear ski 29 being folded over in the direction of the arrow 34 and the steering column on the tip of the front ski 28 is foldable.
  • the quick fastener 20 can be locked after folding, so that unintentional opening can be avoided.
  • FIGS. 1 to 4 Alternatives of the embodiment shown in FIGS. 1 to 4 are possible in a corresponding manner by means of parallelogram links, which are then parts of the frame, it being possible for the parallelogram links to be locked in the respective end positions via corresponding additional struts with end-side sleeve guides.
  • the advantage of the ski bob according to the invention is in particular that simply by loosening the quick-release fasteners or detents 31 and 30, without any further dismantling of ski bob parts, it is possible to clamp and fold them into lockable final states.
  • the ski bob requires only a small space, in particular the front ski 28 can be inserted into slide-in compartments provided on the outer wall of ski gondolas, so that the ski bob can be carried outside the gondola like a ski.
