Definitions

  • the invention relates to a safety slalom rod with a rod lower part which can be plugged into the ground and which is connected to a rod upper part in an elastically resilient manner via at least one bending joint.
  • a known security slalom rod of this type shows a long ringing after a deflection, which is undesirable.
  • the rod must be inserted into the underground to the exact depth. If it is inserted too deeply, the bending joint can be blocked by solidifying snow and the safety effect can thus be nullified. If the insertion is too small, the protruding part of the lower part of the pole may endanger the athlete.
  • the object of the present invention is to improve a safety slalom stick of the type mentioned in such a way that it swings out only briefly after a deflection and at the same time allows greater deviations in the insertion depth into the ground without endangering the athletes.
  • the invention provides that at least two spaced-apart bending joints are provided between the lower rod part and the upper rod part.
  • the series connection of at least two bending joints results in a strong bending damping, so that only a short ringing occurs.
  • the arrangement of a plurality of bending joints at a distance from one another makes it not so easy for these bending joints to be blocked by the solidifying subsurface, and at the same time the insertion depth in the subsurface can vary at least about the joint distance without impairment.
  • two articulated bodies can be provided as bending joints, which rest in their rest position on contact surfaces oriented perpendicular to the rod axis, whereby they are resiliently clamped together by at least one spring.
  • the joint bodies can advantageously be centered in their mutual position relative to one another and be rotationally symmetrical, so that the same deflection forces are required on all sides.
  • a cylindrical one can be particularly easily centered on the joint bodies Recess and assigned a corresponding projection projecting into this recess.
  • joint bodies can be clamped together one behind the other via a common tensioning device, at least one flexible tension member being guided through the joint body and at least one spring being tensioned.
  • the joint bodies can be arranged between end pieces, the end pieces being connected to the lower rod part or the upper rod part. The end pieces can then be penetrated by the flexible tendon and the spring can be supported on at least one of the end pieces.
  • a compression spring through which the flexible tensioning element is guided and held by means of a spring plate, can serve particularly advantageously as a spring.
  • a rope or wire can be used as a flexible tendon, at least one end of which is adjustably held in a threaded bolt to adjust the preload relative to the spring plate.
  • the relative movement of the tendon in the joint bodies can be kept small in that Two springs are arranged symmetrically, advantageously between each of the end pieces and a spring plate.
  • the ends of the rod parts near the bending joint can be hollow and can be positively received on or in the end pieces. At least one of the rod parts can be removably held on the end piece by means of an adapter sleeve, in order to enable the prestressing to be adjusted and adjusted with little assembly effort.
  • the slalom rod can be made particularly light in that at least one of the rod parts is a tube, the free end of which is closed by a tip or a closure cap.
  • the rod parts can be made of thermoplastic material, preferably polycarbonate, in a particularly maintenance-free and corrosion-proof manner. Glass fiber material can be used for particularly resistant slalom sticks.
  • the lower part of the rod can have an external thread, which is preferably a steep thread, to secure it against being pulled out and as an insertion aid.
  • anchoring projections can be spread over the thread approximately transversely to the rod axis, expediently barb-like, so that insertion into the snow is possible with little resistance, but pulling out is opposed to considerable resistance.
  • the anchoring projections can be spread out over the thread or can be brought into contact with the rod.
  • a spreading cone is expediently provided for this purpose, concentrically with the thread, by means of which spreading arms carrying the anchoring projections can be moved from an assembly and disassembly position into their use position.
  • the spreading arms can be designed in a tongue-like manner in a particularly simple manner and yet be very effective, the ends of the spreading arms then emitting the anchoring projections.
  • the spreading arms can be arranged in the extension of a threaded bush which can be screwed onto the thread. Due to their own elasticity, the spreading arms always rest on the expanding cone, it being possible for three to six spreading arms to be expediently provided, which are integral with the thread
  • the extension of this can be made of plastic.
  • the exemplary embodiments of a safety slalom rod shown in the figures have a tubular rod upper part 1 and rod lower part 2.
  • the upper rod part 1 is closed by a cap 3, while the lower end of the lower rod part 2 is closed by an inserted tip 4.
  • the rod parts 1 and 2 are each attached to an end piece 5, 5 ', in the exemplary embodiment the Lower rod part 2 is held detachably on the end piece 5 'by an adapter sleeve 6.
  • the lower rod part 2 can be provided with an external thread 7 over its entire length or part of its length.
  • the rod parts 1 and 2 can be made of thermoplastic, preferably polycarbonate tubes, to save weight. Glass fiber material or aluminum tube can also be used for particularly resistant and elastic safety slalom rods.
  • each bending joint 8 is formed by two joint bodies 9 1 to 9 6 .
  • the joint bodies 9 2 to 9 5 are designed as identical cylindrical disks which have a recess 10 on the one hand and a corresponding projection 11 on the other hand.
  • the recesses 10 and the projections 11 are rotationally symmetrical, the edges 12 of the projections 11 projecting into the recesses 10 being rounded.
  • the recesses 10 are somewhat deeper than the height of the projections 11, so that the joint bodies 9 can abut each other on their abutment surfaces 13.
  • the end pieces 5 and 5 ' are connected in one piece to the outer joint bodies 9 1 and 9 6 and are likewise of circular cylindrical design.
  • Both the end pieces 5, 5 'and all of the joint bodies 9 have a central bore 14, 14', 14 "through which a flexible tensioning element 15 in the form of a rope, preferably a wire rope or a wire, shown only partially in FIG. 1, passes
  • a flexible tensioning element 15 in the form of a rope, preferably a wire rope or a wire, shown only partially in FIG. 1, passes
  • both ends of the flexible tensioning member 15 are held in threaded bolts 16, 16 '.
  • the threaded bolts 16, 16' are guided through spring plates 17, 17 ', with at least the lower threaded bolt 16' being opposite the spring plate 17 'via an adjusting nut 18.
  • the safety slalom rod can bend at one or more of the bending joints 8 and it is brought back into its extended starting position by the biasing force of the springs 20, 20 'via the tensioned flexible tendon 15.
  • the arrangement of many bending joints 8 results in strong vibration damping, so that the extended rest position can be reached again in a very short time without reverberation after a deflection.
  • a threaded bushing 21 is placed on the thread 7 and has four spreading arms 22 extended downwards, at the ends of which there is in each case a hook-like anchoring projection 23.
  • the spreading arms 22 rest on an expansion cone 24 arranged in an extension of the thread 7 and thus form an anchoring device 25, which is shown in the assembly position in FIG.
  • the thread 7 is screwed into the threaded bushing 21 by rotating the lower rod part 2 screwed in, whereby the spreader arms 22 are pressed outward by the spreader cone 24, so that the anchoring projections 23 become caught in the snow.
  • the rod lower part 2 projects beyond the thread 7 approximately by the screw length.
  • the threaded bushing 21, the spreading arms 22 and the anchoring projections 23 are made in one piece from plastic, this plastic having sufficient inherent elasticity that when the thread 7 is unscrewed the arms 22 always bear resiliently against the expanding cone 24.
  • the expansion cone 24 is arranged above the thread 7 on the lower rod part 2.
  • the expanding arms 22 bear against the spreading cone 24, while in the anchoring state by screwing the threaded bushing 21, the expanding arms 22 g over the Stan enlie protrude.
  • the ends of the spreading arms 22 then release the anchoring projections 23.
  • about three to six spreader arms are connected in one piece to the threaded bushing 21.
  • the ends of the spreading arms 22 are ent speaking of the pole circumference broadly formed, in order to achieve the best possible anchoring in the snow.
  • the thread 7 is not guided all the way to the end of the rod.
  • the thread end can be formed by an inserted, somewhat larger tip 4 made of plastic or metal.
