Description

The Invention relates to a training device for performing gymnastic exercises, especially for ski training, with a movable foot contact surface for both Feet of a practicing person.

Out rehabilitation and physiotherapy are so-called wobbly boards known to be a footboard for both Feet as well a lower side approximately centrally arranged, in cross-section, for example, semicircular trained Have tilting bearing, which rests on the ground. This can be simple gymnastic exercises, Among other things, to balance coordination, be performed. Besides, they are aslant running foot pads for bending and posture exercises known.

These individual devices enable not the realization and implementation of complex, in particular sport-specific Movements, as they occur in alpine skiing.

From the US 4,946,160 A is an apparatus for preparatory ski training known. The apparatus has a base on which an upper, about a vertical axis rotatable and tiltable about a horizontal axis platform is mounted. The platform has two half-wheels on the underside, which each act on a ring of the base. The strength of the exerted by the exerciser by changing load on the platform by the feet of the exerciser, from a rotation (about the vertical axis) and a tilting (about the horizontal axis) composite rocking motion of the platform can be adjusted by adjusting the one half wheel against the wreaths and Size of the inclination angle of the platform can be determined by adjusting knobs.

at a one-sided stronger Load with one foot opposite the other foot of the practitioner becomes causes a tilting movement of the platform, at the same time a Side movement is done by rolling the half wheels. For stabilization can the practitioner though sticks use, however, complicates the free mobility of the platform at the same time the safe ascending and descending by two axes considerably.

In the DE 44 08 179 A1 is a skiing simulator for dry training and for testing ski boots when buying described. The device consists of a base, a tiltable on the base in the forward-backward direction and about a vertical axis Erratically supported Erten support plate and a pair of parallel side by side sprung on the support plate and in the transverse direction on both sides tiltable mounted board-like strips, each one Simulate skis.

With Help the inclinability of the support plate on the tilting movement and the horizontal rotation of the support plate about its vertical axis and the mutual limited tiltability of the ledges in relation to each other on the support plate can Skiing occurring movements are simulated. The free, limited rotation of the support plate and the lateral tiltability the board-like last makes it difficult to get on and also to dismount whereby unintentional movements of the stands a not insignificant accident risk for the User recover.

task The present invention is a training device in particular to create ski training, with which improved training and if necessary, rehabilitation of different basic motor characteristics possible is. The device should be versatile and versatile and easier to implement up to highly complex movements allow. This should be easy to use of the device be given and for The user wants this exercise machine to stand out for its high practicability and ease of use distinguished. Furthermore should be a high level of security when using the device, in particular when getting on and off, be achieved.

to solution This object is proposed that the training device a Basic frame with a bracket for a opposite the Basic frame has pivotable and lockable inclination device, in that the inclining device has a foot contact surface Terrain plate bears that across from the tilting device about a transverse to the axis of inclination Tilting tiltable is that on the terrain plate elastic return elements attack and that it can be locked in a predeterminable position and that a locking device for the terrain plate a coupling point to operate having a (ski) floor at least to release the tilt function.

through opposite the base frame swiveling and lockable tilt device can the terrain plate with their foot contact area accordingly aslant be set to simulate different slopes. An increased Slope requires more leg and foot strength during the exercises and elevated the coordinative requirements.

simultaneously is with the side in both directions against a restoring force tiltable terrain plate a representation of different terrain situations and slope conditions allows.

The proposed lockability of the terrain plate simplifies handling and allows in particular a safe ascend of the exerciser on the foot contact surface. In addition, with fixed, only adjustable in inclination terrain plate also selected, simple exercises can be performed, as they are possible directly on a tilt plate.

Especially advantageous here is the operability the locking device with a (ski) floor at least for release the tilt function, because thereby a safe ascend on the exerciser is reached. This is especially for the elderly or anxious and coordinatively weak people of great importance.

There it for Skitraining is recommended, as usual ski poles (with according to the amount of Foot contact surface of the exercise machine plugged extensions) to use these can then also easy to release the locking mechanism used when the practitioner his / her Start position on the exerciser has taken. The locking mechanism is expediently designed so that not only a release, but also a locking possible with the ski pole is, so the terrain plate so that it is determined and also a safe descent of the training device is possible.

advantageously, are those at the site plate engaging, elastic return elements in their number and / or intensity variable.

By reinforcement the elastic return elements in both tilt directions, the tendency to tilt is reduced on both sides. One-sided restoring elements enable a load shift to the side where no reset element or less reset elements or those with lower restoring force are arranged. This is a one-sided load control and Dosage possible, For example, if an accentuation of the load of a leg is necessary, but still in two-legged standing position can be trained.

The tiltable terrain plate can be connected to an adjustable swivel brake. In order to Can adjustably reduce the tilt or tilt sensitivity of the terrain plate which can also be used in combination with the elastic restoring elements possible is.

The above-described training device has a base frame with the tilting device and the terrain plate and forms a basic module. This can according to the invention at least a supplementary module be extended, as a supplementary module at least one against a restoring force rotatable swinging plate provided with a foot contact surface is that over a pivot bearing with an approximately perpendicular to the foot contact surface running Axle with the terrain plate is connectable.

In This expansion stage of the training device can also be performed vibration exercises. there it is possible, by varying the rotational resistance different types of snow but also different terrain forms, e.g. a slope sloping to the side that vibrates when swinging different effort requires to empathize.

Conveniently, the swing plate has a locking mechanism for locking the rotational movement.

Of the Oscillating plate can thereby be completely fixed, in particular for a safe upgrade to the training device, especially then, when the terrain board not in its neutral position. First a release of the Locking mechanism after the upgrade releases the turntable for the exercises.

To the locking of the swing plate consist of the same exercise options with a slightly reduced level of difficulty as with the use only of the basic module, where the practitioner on the site plate stands.

Also the locking mechanism for The swinging plate can be a coupling point to operate with a (ski) floor to lock and release the swing function, so that also the use of a swinging plate this for getting on and off can be set and released by the user.

To An embodiment of the invention can as additional He supplementary module one provided with a two-part foot contact surface be, their separate, independently movable single foot rests plates optionally with the swinging plate or the ground plate via elastic intermediate elements are connectable.

With this supplementary module can the feet individually and independent be tilted from each other and it is thus a simulated edge use possible.

By Locking the swing plate is achieved the same as through Implementation of the additional supplementary module on the terrain plate.

According to a development of the invention, a control device for monitoring the position of a practicing person on the training device be provided, in particular for monitoring the squat position.

there the control device may be an indicator and / or an audible and / or have an optical signal transmitter.

In a practical embodiment the control device has a pull switch and is by means of a length adjustable Zugelementes between a stationary, bottom-side point and a preferably in the hip area of a practitioner Place arranged.

With This control device can the squat position, so the degree of flexion the knee joints monitored become. Due to the adjustable length Tension element is first a default in adaptation to the size of the practitioner and in particular the for the exercise provided squatting position.

exceeds the practitioner the intended squat position by change of position in the direction of extended position, the pull switch is over triggered the tension element and the control device preferably makes it audible attentively. Is the practitioner going? subsequently again at least in the set squat position, the signal is interrupted.
