Definitions

  • the invention relates to a safety slalom rod with a rod bottom part which can be plugged into the ground and which is elastically and elastically bendably connected via a joint to a rod upper part, the joint having at least two rotationally symmetrical joint bodies which, in the rest position, are centered in their mutual position on contact surfaces oriented perpendicular to the rod axis abut each other, wherein at least one flexible tendon is also guided through the joint body, through which they are axially clamped together via at least one spring.
  • a safety slalom rod known from DE-OS 2 428 659 has a single flexure.
  • this slalom pole When used, this slalom pole must be inserted into the snow at an exact depth, whereby the joint should be attached as far as possible below the snow surface to avoid possible injuries. If it is inserted too deeply or the snow is very hard, this will prevent the snow from swinging out over the joint.
  • a slalom rod is known from DE-A 29 02 082, in which the only joint provided is formed by a rubber tube.
  • this joint training is very simple. It is disadvantageous that the elastic properties of the rubber are strongly temperature-dependent and the rubber hose is easily damaged by the sharp ski edges, so that the service life of such slalom poles is severely limited.
  • the object of the present invention is to improve a safety slalom stick of the type mentioned at the outset such that it swings out only briefly after a deflection and at the same time permits greater deviations in the insertion depth into the ground, without endangering the athletes.
  • the invention provides that the joint is formed by at least two bending joints arranged at a distance from one another, each bending joint being formed by two joint bodies, and that all bending joints are braced one behind the other via a common tensioning device and for this purpose by all joint bodies or the flexible tendons are guided.
  • the arrangement of several bending joints results in strong vibration damping, so that the rod straightens up relatively quickly and stands still. Furthermore, by extending the bending joints over a greater length, the safety slalom rod can be used with a relatively large tolerance without there being any risk of injury to the athlete through the firmly anchored lower part of the rod. A further driving in when driving down even a thicker layer of snow is also unnecessary.
  • the relative movement of the tendon in the joint bodies can be kept small in that two springs are provided symmetrically and that the springs are each provided between one of the end pieces and a spring plate.
  • At least the ends of the rod parts near the bend joint can be hollow and the end pieces can be pushed on for sheltered accommodation and easy assembly, at least one of the rod parts being held acceptably on the end piece via a clamping sleeve, in order to facilitate tension adjustment.
  • 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 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 their 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 very effectively, 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 spreading cone, whereby three to six spreading arms can expediently be provided, which are made in one piece with the threaded bushing in an extension of the latter from 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 closure 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 ', the lower part 2 of the rod being held removably on the end piece 5' by a clamping sleeve 6 in the exemplary embodiment.
  • 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 i to 9 s .
  • 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 recess 10 are somewhat deeper than the height of the projections 11, so that the joint bodies 9 can abut one another 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 tendon, only partially shown in FIG. 1, in the form of a rope, preferably a wire rope or a wire, is passed
  • both ends of the flexible bracing element 15 are held in threaded bolts 16, 16 '.
  • the threaded bolts 16, 16' are guided through spring plates 17, 17 ', at least the lower threaded bolt 16' being adjustable relative to the spring plate 17 'via an adjusting nut 18 and thus releases a tensioning device 19, by means of which the pretensioning of the flexible tensioning member 15 can be set, a spring 20 or 20 'in the form of a helical compression spring being arranged between the end piece 5 or 5' and the spring plate 17 or 17 '
  • the inside diameter of the springs 20, 20 ' is somewhat smaller than the inside diameter of the rod parts 1 and 2.
  • 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 is reached again in a very short time after a deflection without reverberation.
  • a threaded bushing 21 is placed on the thread 7 and has four spreading arms 22 extended downward, at the end of which a hook-like anchoring projection 23 is provided in each case.
  • 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. 4.
  • the thread 7 is screwed into the threaded bushing 21 by rotating the lower rod part 2, as a result of which the spreading arms 22 are pressed outward by the expansion cone 24, so that the anchoring projections 23 become caught in the snow base.
  • 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 on the expanding cone 24.
  • the expansion cone 24 is arranged above the thread 7 on the lower rod part 2.
  • the spreader arms 22 rest against the spreader cone 24, while in the anchored state, the spreader arms 22 protrude beyond the circumference of the rod by screwing the threaded bushing 21.
  • 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 designed to be wide in accordance with the circumference of the rod 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 an inserted, somewhat larger tip 4 made of plastic or metal.
