Description

The The present invention relates to a training machine, in particular for strength training, coordination training and / or endurance training, preferably for training or strengthening the skeletal musculature, according to the preamble of claim 1.

apparative Muscle training has both in terms of exercise therapy the prevention and rehabilitation of injuries, such as also in top and mass sports to increase performance and well-being. It is known that with increased Muscle strength and improved neuromuscular control improves the stabilization of increasingly stressed joints can be. To optimize a muscle workout is the use of exercise machines whose function is the mechanical properties the relevant joint and the musculature to be trained, meaningful. Today's training machines have motion axes, which correspond to the so-called cardinal axes of anatomy books, ie starting from upright people only in one of the following three Directions are: vertical, in the running direction (horizontal) or across the direction of travel (horizontal).

The US 4,650,183 A describes a training machine that is designed to measure and / or train the pronation and supination movements of the ankle around a movement axis that at least substantially corresponds to the anatomical / functional joint axis of the ankle.

Of the present invention is based on the object, a training machine to indicate the training of the ankle, which is a more optimal workout allows.

The The above invention is achieved by a training machine according to claim 1 solved. Advantageous developments are the subject the dependent claims.

According to the proposal provided that the foot or foot receptacle towards at least substantially the projection of the movement axis in the foot sole plane of the foot or a support plane the foot intake during the pivoting of the foot is displaceable about the movement axis. this makes possible a better workout. In particular, such a superimposed translational movement of the ankle or translational Displacement of the joint axis of the electric joint in pronation and Considered supination movements of the foot be or take place.

A basic idea of the present invention is, at least a movement axis of the exercise machine not on one of the Kardinalachsen but at least one anatomical-functional Adjust the joint axis.

The The present invention relates to the training of the foot ankle, namely the complex of the Ankle, hereafter referred to as ankle joint. For mechanical loads the upper and lower ankle act as a coupled system, like a sloping hinge joint around the pronation and Supine movements of the foot to follow. In the proposal Training machine is preferably at least one movement axis provided according to claim 7.

One Another aspect is that the exercise machine is formed such that the movement axis individually is adaptable to the anatomy of the exerciser. For this the movement axis is adjustable accordingly.

Out sports medicine perspective possesses a training machine, the based on anatomically functional and biomechanical knowledge, large Advantages over conventional training machines. Any muscle that connects two bones together can be a joint or stabilize it together with its antagonist. The muscle controls the joint movement around the anatomical-functional Joint axis. The consequence of this is that a workout this muscle with the goal of performance increase as possible in its functional level, which dictates the axis of articulation, take place should. Only then can the mechanical properties of the Muscle and the biomechanics of the corresponding joint at its Training be considered. With regard to prophylaxis of sports injuries represents the proposed Exercise machine thus represents a significant progress.

Of Further, the efficiency of training is essential by the invention improved.

From Not only patients of the present invention can Rehabilitation of injuries, but also athletes in general for prophylactic training of the muscles and joints, benefit.

The Invention is basically for all types of Training machines used, especially for strength training machines.

The term "exercise machine" is to be understood in a broad sense as meaning each Type of exerciser includes.

Further Advantages, aspects, characteristics and features of the present invention result from the claims and the following description preferred embodiments with reference to the drawing. It shows:

1 shows a schematic representation of a proposed training machine 1 in the sense of the present invention. The training machine 1 is for training the ankle 2 a foot 3 educated.

The training machine 1 according to the proposal, at least one movement axis 4 on, the anatomical or functional joint axis of a human joint - here the ankle 2 - At least substantially corresponds and / or deviates from the coordinate axes mentioned above.

The movement axis 4 is in 1 indicated by dash-dotted lines. The plan view and the substantially horizontal section according to 2 shows the movement axis 4 also.

The movement axis 4 in the training machine 1 runs in the illustrated embodiment preferably at least substantially by the angle α of about 42 ° +/- 9 ° to the sole of the foot 5 inclined, more preferably in the direction of upward, as in 1 indicated.

The movement axis 4 is alternative or in addition to the main plane H of the foot 3 in the direction of rotation at least substantially inclined by the angle β of about 23 ° +/- 10 ° inwards, wherein the main plane H of the foot 3 vertical or perpendicular to the sole of the foot 5 and running in the direction ( 2 ).

The training machine 1 has a foot image 6 for receiving the foot 3 , especially the sole of the foot 5 , on. The foot picture 6 is in particular plate-like, rigid, sole-like and / or formed like a shoe.

The illustration shows the foot image 6 a heel pick 7 and a holder 8th for the forefoot, in particular in the area of the ankle, for example a preferably adjustable band.

The training machine 1 preferably has a joint 9 on, that's the foot pickup 6 around the movement axis 4 rotatable or pivotable, in particular on a frame G stores. The movement axis 4 is preferably through the joint 9 established.

The movement axis 4 preferably runs through the ankle joint 2 , To be able to adapt this and / or the movement axis 4 in their tendency to change, the training machine instructs 1 preferably suitable adjusting devices. For example, the heel pickup 7 and / or mount 8th be adjustable so that the foot 3 is displaceable or adjustable in the longitudinal direction (running direction). Next, the already mentioned inclination of the movement axis 4 for example, by appropriate transverse joints between the joint 9 and foot recording 6 or be adjustable in any other suitable way.

The training machine 1 preferably has a receptacle or holder 10 for the foot 3 associated lower leg 11 on. The recording 10 For example, a cushion 12 and an associated band 13 , For example, a Velcro, or the like, to secure fixation of the lower leg 11 to enable. Particularly preferred is the recording 10 formed such that the lower leg 11 in the area of the knee 14 or directly below it is fixable. For optimal adaptability is the recording 10 then especially in height or relative to the foot 6 or on the frame G adjustable.

Preferably, the respective movement about the movement axis 4 take place against a particular static, dynamic and / or adjustable force. Particularly preferably, the force acts in the return direction. However, in principle, a force only when moving - for example, in the manner of a frictional force - occur. Furthermore, the force can also vary away or angle-dependent and / or vary depending on the direction of movement.

In the illustration example, the training machine instructs 1 An institution 15 for generating a corresponding force, in particular a restoring force on. In particular, the device causes 15 a provision of foot recording 6 in a neutral, for example, at least substantially horizontal position.

The device 15 has in the representation example one at the joint 9 or at the foot 6 attacking pivot lever 16 with an associated spring 17 on. However, other constructive solutions are possible here.

In the illustration example, the training machine instructs 1 in particular only one axis of movement 4 on. However, it is also possible to superimpose several axes of motion and / or to allow more complex movements.

Suggested is the foot 3 or the taking 6 - At least with a movement component - in a direction according to the double arrow 19 in 2 , in the foot plane (level of the sole of the foot 5 or plate or main level of foot recording 6 ) displaceable. The direction of displacement 19 runs in the foot plane and substantially perpendicular (+/- 10 degrees) to the projection of the movement axis 4 in the foot plane. This allows a more optimal training, as the joint axis of the ankle 2 during the pivoting movement translationally in the direction of displacement 19 can shift and the proposed displacement or displaceability allows this.

The proposed displaceability is possible, for example, by a corresponding carriage-like guide, guide in slots, not shown, guide means of roller rails, a telescopic guide or the like. In particular, the foot is 6 accordingly in the direction of displacement 19 movable from one in 1 indicated carrier 21 or the like, for example, with the joint 9 connected or about the axis of movement 4 is pivotable, stored or held.

In addition to the aforementioned displaceability are preferably the heel pickup 7 and / or mount 8th for adaptation to the respective foot 3 , in particular its size, adjustable or adjustable.

Particularly preferably, the displacement takes place in the direction of displacement 19 free. In this case, the lower leg 11 preferably by an additional recording 20 additionally fixed, especially in the area of the lower end or adjacent to the ankle joint 2 , as in 1 indicated.

The two shots 10 . 20 are preferably spaced from each other and / or in the longitudinal extent of the lower leg 11 added. So is a secure fixation of the lower leg 11 possible.

However, it is also possible in principle, the holder 10 and / or the holder 20 form such that the lower leg 11 and / or the knee 14 only from the front or from the back against a corresponding pad 12 or the like is pressed. In particular, then the upholstery 12 in the field of recording 10 and a not shown further pad in the recording 20 on opposite sides of the lower leg 11 arranged.

Alternatively or additionally, other investments or fixations of the lower leg 11 impossible.

Instead of free displacement, the foot can 3 or foot recording 6 also be positively guided displaced or in its displacement with the pivoting about the axis of movement 4 be coupled. In particular, this can be done via a not shown gear, a Bowden cable or the like.

Alternatively or additionally, the pivoting of the footrest 6 around the movement axis 4 and / or moving in the direction of displacement 19 also via an optionally common drive or via separate drives.

The proposed training machine 1 allows a particularly effective and anatomically correct training of the ankle 2 ,
