Description

The invention relates to exercise or exercise equipment Learning the movements of the parallel ski turn, where a roller carriage on rails against the force of Move rubber bands or springs through the person practicing becomes.

With sports equipment for practicing the movements in skiing should do parallel swing exercises as precisely as possible actual movements like skiing be adapted to the ski slope.

Sports equipment according to the preamble of claim 1 known from the utility model document Federal Republic Germany Roll number G 84 11 358.8 main class A6 3B 69/18 and the patent specification Federal Republic of German country DE 23 18 455 C2 file number P 23 18 455.6-15. Fer He has the Freizeit Möbel GmbH Erhardt, PO Box 1369, D- 7450 Hechingen, produces such sports equipment, the However, production resumed a few years ago poses.

None of the three sports equipment comes with original skis Driver's footwear, that is, with standard ski boots trained. None of the known devices safeguards practitioners largely against falls.

On the patent or utility model protected Sports equipment must be used for parallel swing exercises with the feet a partial arc can be described. However, this is with the actual parallel turn on the ski slope hardly ever the case.

The heel push effect can be seen on the patented Sports equipment not at all and on the utility model Only achieve sports equipment with a complicated detour  the feet up and over a partial arc another partial arc from the back to the front ahead, as it hardly ever happens in practice.

The three sports equipment are operated without noise reduction ben.

None of the sports equipment can be adjusted to fit the height, weight and / or level of the exerciser:
adjustable device inclination - which corresponds more or less slope slope; adjustable resistance against which the roller carriage is moved; adjustable rail track route; adjustable heel push effect; adjustable heel and toe holders; adjustable ski stick handles; adjustable harness and waist belt.

The invention seeks to remedy this. The invention the task is based on generic ski training devices technically simple, stable, ge need to improve so that a still further approximation to the actual movements is made possible when skiing. This is as high as possible Ease of accident prevention and as low as possible Noise pollution.

This task is carried out in a generic facility by the characterized features of claim 1 ge solves.

Claims 2-7 are advantageous according to the invention liable new or further developments.

Achievable advantages of the invention.

The sports equipment is of stable, simple construction and therefore easy and inexpensive to manufacture.

The heel pushing effect and the edging is without compli adorned technology and without complicated foot or leg movements  due to the asymmetrical swing element suspension achieved in a simple manner. The hip rotation and Inclination naturally arises in the Versensubsch and when edging close to nature as with Parallel turn on the ski slope. The prerequisite is Ruhi ge, slightly bent upper body posture, like the Pi parallel swing.

The asymmetry of the swing element suspension is adjustable bar for more or less heel thrust and more or less sporty people. The larger the selected asymes trie is the greater the heel thrust effect and vice versa returns. It also causes more edging due to the Asymmetry also stronger heel push effect with strength kerer hip rotation and inclination and vice versa.

The rail inclination is adjustable for more or less advanced people according to more or less Slope on the ski slope.

The rail route that the roller carriage travels is adjustable for different parallel swing width for longer or shorter legs or for more or less advanced people.

Two securing brackets ( 5 ) secure in connection with the double wheel flanges of the four double wheel flange rollers ( 6 ) the roller carriage ( 1 ) against derailment during operation and transport even if the rubber band ( 14 ) would fail. The double-track rim rollers ( 6 ) distribute the lateral pressure on the rails, which arises alongside the vertical pressure when the pair of rails is inclined, evenly on both rails. The use of plastic material for the double track roller ( 6 ) favors low noise, which is improved a little if ball or angular roller bearings are used instead of cheaper plain bearings.

The tensile resistance of the rubber band ( 14 ) - when moving the roller carriage on the rails - is adjustable according to the pressure the smaller, larger, lighter, heavier, inexperienced or advanced people exert laterally on the ski slope during the parallel swing weight shift.

It is trained in standard ski boots. That guarantees when practicing the remaining knees and lower legs in the template keeping enforced by norm ski boots becomes and an important prerequisite for technically rich tig executed parallel turns; closes un desired tilting in the ankle area Bend forward and backward only as far as the ski boots allow. Analogous to real skiing.

The toe holder ( 22 ) and heel holder ( 23 ) prevent unintentional sliding off the footbed ( 16 ) and allow entry into the footbed ( 16 ) only from above and the exit only upwards. They are adjustable for ski boots with standard ski boot soles according to DIN 7880, Ö-Norm S 4035, ISO, UNI 007. For children's ski boots, interchangeable heel and toe holders are fitted, which are appropriate for the narrower and shorter ski boot soles.

The ski poles are made of weak-walled metal tube ( 28 ) for safety reasons, so that it can withstand the vertical pressure on it, but only offers little resistance to lateral pressure, possibly deforming and thus largely preventing injuries. A rubber or plastic hose ( 31 ) protruding slightly beyond the tip of the ski stick prevents slipping or damage to the surface on which the tip of the ski stick is placed. The rubber or plastic handles ( 30 ) are infinitely adjustable at any height for smaller or larger people by simply loosening or tightening a hose screw ( 34 ).

The fall arrest device ( 24 ) with its safety belt ( 26 ) and waist belt ( 27 ) can be adjusted by a clasp so that a person falling during training long before it falls to the ground is caught after a small fall. The fall arrester is quick and easy to disassemble and assemble and takes up little space when folded. Their triangular pyramid shape offers high stability, especially since a falling person with their focus is caught in the center of the pyramid. At the same time, the triangular pyramid shape gives exercisers plenty of leeway.

Due to the fall arrest device ( 24 ), the device is un accident prevention-friendly, especially for beginners or inexperienced skiers, making a decisive contribution to breaking the inhibition threshold that arises from fear of injuries in the event of a fall and prevents the persons mentioned from doing the parallel turn technically correct to try or to execute.

Advanced skiers can practice endurance and body control - without a high risk of falling - for example by making parallel turns without ski poles or on one leg.

Due to the noise reduction, the sports equipment is residential easy to use and prevents excessive nuisance neighbors.

All settings - for people of different sizes, weights and levels of advanced ability - can be carried out quickly, easily and without any problems.

With the sports equipment, exercisers can joint and mus Exercise movements with very realistic ski technique as with the parallel turn on the ski slope under high Un case prevention friendliness.  

In the following the invention will be described with reference to an execution path drawings he closer purifies.

Sports equipment for parallel ski swing movements Show it:

Fig. 1 rear view of the sports equipment;

Fig. 2 top view of Fig. 1, but without fall arrest device and without ski sticks and with the roller carriage ( 1 ) in the rest position. According to the preamble of claim 1, the invention relates to:

• a) A roller carriage ( 1 ), which is held in its rest position by a rubber band ( 14 ) in the middle of the rail with its four double track rollers ( 6 ) on a pair of rails ( 8 + 9 ) made of metal. The roller carriage ( 1 ) can be moved in the direction of the rail ends against adjustable tension resistance of the rubber band ( 14 ).

It has a parallel to the pair of rails Rol lenwagenboden ( 4 ) with a front wall ( 2 ) and a rear wall ( 3 ), which are arranged vertically upwards and pa rallel to the pair of rails ( 8 + 9 ). They are as wide as the bottom of the roller carriage ( 4 ) and can be narrower at the top.

At each outer lower end of the front wall ( 2 ) and the rear wall ( 3 ) is a hole that receives one of the four roller axes ( 7 ). On the roller axles ( 7 ) a double track roller ( 6 ) is rotatably supported ge.

On the outside of the front wall ( 2 ) and on the rear wall ( 3 ) in each case at the bottom center there is a safety bracket ( 5 ). These slide with the angled part close to the pair of rails ( 8 + 9 ) along with the rail len roller ( 1 ) without touching the rails.

In the middle of the roller carriage floor ( 4 ) there are holes or screws for receiving rubber band fastening parts.

• b) The straight pair of rails ( 8 + 9 ) is firmly connected at its ends to two cross-struts ( 10 ). They give the pair of rails support and limit the path of the roller carriage ( 1 ) at the ends of the rails.

Two further end limit cross braces ( 11 ) can be removed or installed in different positions between the rails ( 8 + 9 ). They can be used to shorten the distance covered by the roller carriage.

The two permanently connected cross struts ( 10 ) rest at their front (toe-side) ends on a fixed foot ( 12 ). They rest at their rear (heel-side) ends on one of interchangeable feet ( 13 ).

A third foot ( 12 or 13 ) is fixed in the middle of the rail at the front and replaceable in the middle of the rail at the rear. They prevent the rails from bending under load.

Interchangeable feet ( 13 ) are available as a set of three pieces in several sizes. Mounting larger or smaller feet from behind results in a larger or smaller angle of inclination towards the bottom when installing the device.

Corresponding to the inclination of the rail pair res ( 8 + 9 ), the front fixed feet ( 12 ) are bent upwards at their outer ends.

The interchangeable feet ( 13 ) are received by receptacles ( 35 ) or threaded sockets ( 35 ) at the rear on the two permanently connected cross struts ( 10 ) or the middle foot in the middle of the rear rail ( 9 ).

The rails ( 8 + 9 ) and the end limit cross braces ( 10 + 11 ) are made of rectangular or round metal tube. Rubber or plastic pads are attached between the points with the ground or roller carriage floor ( 4 ).

• c) There are two rocking elements ( 15 ) in the roller carriage ( 1 ). Each swing element ( 15 ) has a footbed ( 16 ) that is slightly wider and longer than a standard ski boot sole. On each narrow side of the footbed there is a side part that is bent upwards ( 17 + 18 ). The front side part ( 17 ) is lower than the rear side part ( 18 ). Both sides can be narrower at the top than at the footbed.

In the middle at the top, each side part ( 17 + 18 ) has a slide bearing bore ( 19 ) and vertically below it further slide bearing bores ( 19 ) at equal distances from each other.

In the front wall ( 2 ) and in the rear wall ( 3 ) of the roller lenwagens ( 1 ) there are two rows of holes ( 20 ) perpendicular to each other. Their lateral row spacing corresponds approximately to the width of the ski guide for parallel slope turns. Your distance from the upper edge and also the vertical distance of the bores ( 20 ) in the front wall ( 2 ) matches the plain bearing bore distances ( 19 ) of the front side parts ( 17 ). The rear wall ( 3 ) and rear side parts ( 18 ) match in the same way.

Each rocking element ( 15 ) with a bearing axle screw ( 21 ) in the front wall ( 2 ) and a further bearing axle screw ( 21 ) in the rear wall ( 3 ) can be pivoted around a plain bearing bore ( 19 ). The front wall ( 2 ) and front side part ( 17 ) as well as rear wall ( 3 ) and rear side part ( 18 ) face each other. In the rest position, the footbeds ( 16 ) hang parallel to one another and to the roller carriage floor ( 4 ).

The bearing axle screws ( 21 ) are always mounted closer to the roller carriage floor ( 4 ) on the front wall ( 2 ) than the bearing axle screws ( 21 ) on the rear wall ( 3 ). This results in the asymmetry of the swing element suspension.

The mutually vertically arranged slide bearing bores ( 19 ) in the side parts ( 17 + 18 ) and the equally perpendicular bores ( 20 ) in the front and rear wall ( 2 + 3 ) equip the mounting of the bearing axis screws ( 21 ) different heights to the roller carriage floor ( 4 ). The greater the selected height difference of the bores ( 20 ) between the front and rear walls ( 2 + 3 ), the greater the asymmetry of the swing element suspension and vice versa.

Each footbed ( 16 ) has several bores in its center at the front and rear, in which a toe holder ( 22 ) is attached at the front and a heel holder ( 23 ) at the rear, each with a screw. The toe holders ( 22 ) encompass the standard ski toe soles of an exercising person from the front and from the sides and the heel holder ( 23 ) the ski boot heels from the rear and from the sides.

Because of the different lengths of the standard ski boot soles, the heel and toe holders ( 23 + 22 ) are fastened in bores of the footbeds ( 16 ) that are closer together or further apart.

• d) A highly elastic rubber band ( 14 ) is fastened to the middle of the two permanently connected cross struts ( 10 ) and the middle of the roller carriage floor ( 4 ) by means of brackets and screws. The tension resistance of the rubber band is adjustable. On the one hand by more or less pretension, that is, the rubber band is mounted more or less stretched, on the other hand by changing the rubber band against one with more or less tensile resistance.
• e) The fall arrest device ( 24 ) has the shape of a blunt triangular pyramid. Three pipes inclined in a pyramid shape are connected to each other at the top and bottom by three horizontally attached cross-connection pipes. The lower ends of the pyramid-shaped tubes form the pyramid feet ( 25 ), which are covered with soft, non-slip material (rubber or plastic).

The pipes can be detached using threaded sockets screwed or put together by means of sleeves or collapsible.

At the upper blunt end of the triangular pyramid - in the middle of one of the horizontally guided cross-connecting pipes - an adjustable safety belt ( 26 ) is attached and at the free end of an adjustable waist belt ( 27 ).

The two pyramid feet ( 25 ) - below the Querver connection pipe to which the safety harness ( 26 ) is attached - can be detachably screwed to the two outer interchangeable feet ( 13 ) of the pair of rails ( 8 + 9) using threaded sockets or plugged together using plug sleeves.

• f) The ski poles are made of metal tubing. On each ski pole ( 28 ) is a ring-shaped stop ( 29 ) near the lower end. Up to this stop, the lower end of the tube (the tip of the ski pole) is covered by a rubber or plastic tube. The hose protrudes a little above the metal pipe end. The hose and the stop ( 29 ) can also be replaced by a rubber or plastic cap.

At the upper part of the ski pole ( 28 ) is a tubular rubber or plastic ski pole grip ( 30 ), which can slide along its hole on the ski pole ( 28 ). The upper part of the handle has a plate-like reinforced edge. The lower part of the handle is reinforced to form a flange ( 32 ). The flange has two vertical slots and a horizontal groove. In the groove is a hose tie ( 33 ) with a lock and hose tie screw ( 34 ) for attaching the ski stick handle ( 30 ) on the ski pole ( 28 ) at any height. The upper ski pole ( 28 ) end is closed with a plastic or rubber cap.
To a) -f)

The roller carriage ( 1 ) and the rocking elements ( 15 ) are made of sheet metal, which for reasons of stability are either provided with beads or the edges of which are bent.

Instead of metal, plastic material can also be used. The ski pole tubes ( 28 ) can also be made of plastic.

To reduce operating noise, the roller carriage ( 1 ) and the rocking elements ( 15 ) are lined with noise-damping material and the pair of rails ( 8 + 9 ), the feet ( 12 + 13 ) and the end limit cross-members ( 10 + 11 ) are filled with noise-damping material.
