Definitions

  • the invention relates to a support stick with a handle and a shaft; it relates in particular, but not exclusively, to a ski pole which also has a snow plate at the lower end.
  • Ski poles have long been known for both downhill and cross-country skis.
  • the shaft is formed in one piece and consists, for example, of a one-piece tube which is provided with a tip on its underside.
  • a handle is placed on the one-piece tube, for example in the form of a sword handle or in traditionally with a loop.
  • the ski pole has a certain elasticity against bending loads, but is completely stiff in the axial direction. When a skier falls, it often happens that he falls in the axial direction against the handle of the ski pole.
  • the invention is therefore based on the object of providing a support stick which largely helps to avoid overloads of the type mentioned.
  • the above-mentioned object is achieved in a support stick in that the shaft is designed telescopically with elastically telescoping outer and inner tubes.
  • the inventive design of a support stick can be elastically shortened or pushed in over a certain stroke, for example in the order of magnitude of 50 to 150 mm, under considerable stress that occurs.
  • the load required for shortening can be there be chosen from the outset in such a way that they are adapted to the weight and forces of the pole user, for example also to the driving behavior of a skier. Suitable, against the force acting elastic forces are in the order of 100 to 400 N.
  • a holding tube is provided which is fixedly connected to a connector and the upper tube part and on which the handle is placed, one end of a spring arrangement being fixed on the connector part and the connector being inserted firmly in a tube piece.
  • the holding tube of one of the two has an axial extension; which protrudes into a corresponding axial recess of the connecting part and is also secured in this by means of the screws in that they penetrate the shoulder, while on the other floor the connecting part has an axial shoulder which is inserted into a corresponding axial recess of the holding tube and fixed with it connected is.
  • the two poles can be connected to one another, so that a long rod is formed which can be used for poking at avalanche victims, where the length of a ski pole alone is generally too short.
  • the pipe parts are made of aluminum and / or polyester. As far as they are made of aluminum, at least one is the pipe parts on the side facing the other tube part are provided with a coating, so that the two tubes slide well on one another and no additional frictional forces are opposed to the pressure due to the stacking.
  • polyester coatings or Teflon coatings or other galvanized layers can be used as the coating.
  • the handle can have a mushroom-like widening of the surface, so that there is a large impact surface when the body hits, which supports the injury-preventing properties of the ski pole according to the invention.
  • a preferred embodiment is characterized in that the holding tube part is screwed to the connecting part and / or the tube, it being provided in particular that the spring arrangement has a gas pressure spring with a gas-filled cylinder and a piston guided therein .
  • the force to be used to push the gas pressure spring together is determined by the predetermined gas pressure within the spring.
  • the predetermined relatively high operational force for pushing together in ski poles ensures that there are no disadvantages with normal driving, with support and pushing with both arms.
  • the force to be pushed together is adapted to the respective driver, e.g. B. becomes a A force of 200 N is specified for heavy, sporty skiers, while a force of 120 to 150 N can be sufficient for lighter skiers.
  • Another preferred embodiment provides a gas pressure-filled metal bellows or metal hose as the spring part.
  • the ski pole 1 has a shaft 2, which consists of two telescopically telescopic pipe parts 3 and 4.
  • the tube part 3 facing or connected to a handle 6 is the tube part with the larger diameter which surrounds the other tube part 4.
  • the pipe part 4 is the one of the two pipe parts facing the tip of the ski pole 1.
  • the handle 6 is a so-called epee handle. In principle, a conventional handle with a loop could also be used.
  • a spring 7 in the form of a gas pressure spring, which has a cylinder 8 and a piston 9 which is displaceable therein in relation to the gas pressure located there.
  • the ends of cylinders 8 and pistons 9 are each fixed in a different tube part 3 or 4. While the cylinder 8 is fixed in a further pipe part 3 facing the handle 6, the piston 9 is fixed in the narrower pipe part 4 reaching towards the tip of the ski pole 1.
  • the end 11 of the piston rod 9 facing away from the cylinder 8 is provided with a rough peripheral bevel 12 for better anchoring.
  • a connector 14 is provided, which consists of plastic, preferably of polyurethane.
  • the fitting 14 fitted into the tubular part 4 has a cylindrical outer circumference and is provided on the front end 16 facing the piston rod 9 with an axial blind bore, corresponding to the dimensions of the piston rod 9.
  • a transverse bore 18 extends below the blind bore, perpendicular to the cylindrical outer circumference, that is to say in the radial direction.
  • the transverse bore 18 serves to fix the connecting piece 14 by means of a clamping sleeve or a grooved pin 19.
  • the connecting piece 14 is press-fit with the addition of adhesive (preferably cyanoacrylate Adhesive) for anchoring with the piston rod 9 at the rough bevel 12.
  • connection part 27 is also attached to the end 26 of the cylinder 8.
  • the pressure pipe connection part 28 is provided in an analogous manner with a rough peripheral bevel 29 for better anchoring.
  • a connection part 27 is provided, which consists of plastic, preferably also of polyurethane.
  • the connection part 27 has a cylindrical outer circumference and is provided at one end 30 with an axial blind bore, corresponding to the dimensions of the pressure pipe connection part 28.
  • a bore 31 extends perpendicular to the cylindrical outer circumference, that is to say in the radial direction.
  • the connecting part 27 is fixed in the tubular part 3 by a clamping sleeve or a notch pin 32 passing through the bore 31.
  • the connecting part 27 is press-fitted with the addition of adhesive (preferably cyanoacrylate adhesive) for anchoring the pressure pipe connecting part 28 onto its rough ground section 29.
  • the handle 6 is plugged directly onto the end of the tubular part 3.
  • the cylinder 8 is under gas pressure, which can be adjusted as desired when filled and can thus be adapted to the forces and the weight of the user of the support stick.
  • the pressure of the gas can be set so that forces of 120, 150, 180 or 200 N corresponding to an overlying mass of about 12, 15, 18 or 20 kg are required to compress the piston-cylinder unit.
  • an oil filling 34 or a damping ring 35 is additionally provided which, as end position damping S1 with oil, opposes a greater counterforce to the compressive force acting on the piston, so that the piston which is pressed in progressively extends into this region is braked before it reaches its end position enough. A dampened stretching of the support pole or ski pole is thus achieved.
  • a seal 40 can be provided as a further embodiment, for example in the region of the lower end of the gas pressure spring 8, which ensures a seal against the wall of the tube part 3.
  • the head end of the handle 6 of the ski pole is penetrated by a pressure regulating screw 41.
  • the action of the seal 40 pushes the air between the wall of the tubular part 3 and the outer jacket of the gas pressure spring 7 through a bore 42 or 43 in the pressure regulating screw 41.
  • the support or ski pole can then be subjected to pressure forces of, for. B. 120 N, 150 N or 180 N are compressed.
  • the gas spring element ie the gas pressure spring 8 is then, for example, only with a pressure below the usual setting values, for. B. with 100 N, set and then only has the task of damping the stick after pushing it back to its original position.
  • the following components, which are assigned to the gas pressure spring 8, are also present in a function that is known in principle: a speed and damping-regulating labyrinth piston system 52, a seal 53, a guide piece 55 and an O-ring 54 at the upper end.
  • the ski pole according to the invention can now be used in a completely conventional manner when skiing, especially when descending.
  • the gas spring is not compressed due to the given indentation force, so that no differences are noticed compared to conventional ski poles.
  • the gas spring gives way and avoids serious injuries such as broken ribs.
  • the ski pole according to the invention can not only be used for downhill skiing, but also with a suitable design of the gas pressure for cross-country skiing, and not only to avoid injuries, but also to make skiing easier, more uniform and to achieve better acceleration.
  • the gas pressure is set in such a way that the ski pole is retracted telescopically over a certain area during normal running by pushing with both poles. When the repulsive force of the skier diminishes, the gas pressure has an effect, pushes the ski pole apart and thus gives the skier additional post-acceleration, which in particular makes the push-off process more even and thus more comfortable when skiing.
  • ski pole according to the invention While a preferred exemplary embodiment of the ski pole according to the invention is shown in the above description, the features of the invention disclosed in the description, in the drawing and in the claims can be used individually as well as in suitable combinations for realizing the invention in their ver different embodiments may be essential.
  • the unit consisting of spring and connecting parts and surrounding protective tube can also be used for retrofitting conventional ski poles.
  • An important field of application of the invention is medical sticks and crutches. As is known, people with walking difficulties who rely on stick-like walking aids often suffer from pain in the arm and wrists, caused by long-term overuse. Experiments have shown that the invention can provide effective remedy or at least relief.
