Description

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

Apparative muscle training has established itself both in movement therapy with regard to the prevention and rehabilitation of injuries, as well as in top and popular sports to increase performance and well-being. It is known that with increased muscle power and improved neuromuscular control, the stabilization of increasingly stressed joints can be improved. In order to optimize muscle training, the use of exercise machines, the function of which takes into account the mechanical properties of the respective joint and the musculature to be trained, makes sense. Today's training machines have axes of movement that correspond to the so-called cardinal axes of the anatomy books, so starting from the upright person only in one of the following three directions: vertically, in the direction (horizontal) or transverse to the direction (horizontal).

The US 4,650,183 A describes a training machine according to the preamble of claim 1, which is designed for measuring and / or training the pronation and supination movements of the ankle about a movement axis, which at least substantially corresponds to the anatomical / functional joint axis of the ankle.

The present invention has for its object to provide a training machine for training the ankle, which allows a more optimal training.

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

According to the proposal, it is provided that the foot or foot receptacle in the direction at least substantially perpendicular to the projection of the movement axis in the Fußdes Foot or a support plane of the foot receptacle during pivoting of the foot receptacle is displaceable about the movement axis. This allows a better workout. In particular, such a superimposed translational movement of the ankle or translational displacement of the joint axis of the current joint can be taken into account during pronation and supination movements of the foot.

A basic idea of the present invention is not to align at least one movement axis of the exercise machine on one of the cardinal axes, but to adapt to at least one anatomically-functional joint axis.

The present invention relates to the training of the foot or ankle, namely the complex of the ankle, hereafter called ankle for short. In mechanical loading, the upper and lower ankle act as a coupled system, such as a slanted hinge joint, to follow the pronation and supination movements of the foot. In the proposed training machine preferably at least one movement axis is provided according to claim 7.

Another aspect is that the exercise machine is designed such that the movement axis is individually adaptable to the anatomy of the exerciser. For this purpose, the movement axis is adjusted accordingly.

From a sports medicine perspective, a training machine based on anatomically functional and biomechanical knowledge has great advantages over conventional exercise machines. Any muscle that connects two bones can move or stabilize a joint together with its antagonist. The muscle controls the joint movement around the anatomical-functional joint axis. The consequence of this is that a training of this muscle with the aim of increasing performance as possible should take place in its functional level, which dictates the axis of the joint. Only in this way can the mechanical properties of the muscle and the biomechanics of the corresponding joint be taken into account during its training. With regard to the prophylaxis of sports injuries, the proposed training machine represents a significant step forward.

Furthermore, the efficiency of the training is significantly improved by the invention.

The present invention not only benefits patients for the rehabilitation of injuries, but also athletes in general for prophylactic training of the muscles and joints.

The invention can basically be used for all types of exercise machines, in particular for strength training machines.

The term "exercise machine" is to be understood in a broad sense as embracing any type of exerciser.

Fig. 1 shows a schematic representation of a proposed training machine 1 in the context of the present invention. The exercise machine 1 is designed to train the ankle 2 of a foot 3.

According to the proposal, the training machine 1 has at least one movement axis 4, which at least substantially corresponds to the anatomical or functional joint axis of a human joint-in this case the ankle 2 -and / or deviates from the coordinate axes mentioned at the outset.

The movement axis 4 is in Fig. 1 indicated by dash-dotted lines. The plan view or, in accordance with the substantially horizontal section Fig. 2 shows the movement axis 4 also.

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

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

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

In the illustrated example, the foot receptacle 6 has a heel receiver 7 and a holder 8 for the forefoot region, in particular in the region of the toe ankle, for example a preferably adjustable band.

The exercise machine 1 preferably has a hinge 9, which the Fußauf acquisition 6 about the movement axis 4 rotatable or pivotable, in particular on a frame G, superimposed. The movement axis 4 is preferably defined by the hinge 9.

The movement axis 4 preferably runs through the ankle joint 2. In order to be able to adapt this and / or to change the inclination of the movement axis 4, the exercise machine 1 preferably has suitable adjustment devices. For example, the heel holder 7 and / or holder 8 may be adjustable so that the foot 3 in the longitudinal direction (running direction) is displaceable or adjustable. Furthermore, the already mentioned inclination of the movement axis 4 can be adjustable, for example, by means of corresponding transverse joints between the joint 9 and the foot receptacle 6 or in another suitable manner.

The exercise machine 1 preferably has a receptacle or holder 10 for the foot 3 associated lower leg 11. The receptacle 10 may, for example, a pad 12 and an associated band 13, such as a Velcro, or the like, to allow a secure fixation of the lower leg 11. Particularly preferably, the receptacle 10 is formed such that the lower leg 11 in the region of the knee 14 or immediately below it is fixable. For optimal adaptability, the receptacle 10 is then adjustable, in particular in height or relative to the foot receptacle 6 or on the frame G.

Preferably, the respective movement about the movement axis 4 can take place against a particularly 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 illustrated example, the exercise machine 1 has a device 15 for generating a corresponding force, in particular a restoring force. In particular, the device 15 causes a provision of the foot 6 in a neutral, for example, at least substantially horizontal position.

The device 15, in the illustration example, has a pivoting lever 16, which acts on the joint 9 or on the foot receptacle 6, with an associated spring 17. However, other constructive solutions are possible here.

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

According to the proposal, the foot 3 or the foot receptacle 6 - at least with a movement component - in a direction according to the double arrow 19 in Fig. 2 in the foot plane (plane of the sole of the foot 5 or plate or main plane of the foot 6) displaceable. The displacement direction 19 extends 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, since the joint axis of the ankle 2 during translation can translationally shift in the displacement direction 19 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 receptacle 6 is correspondingly displaceable in the displacement direction 19 of a in Fig. 1 indicated carrier 21 or the like, for example, connected to the hinge 9 and is pivotable about the movement axis 4, stored or held.

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

Particularly preferably, the displacement in the displacement direction 19 is free. In this case, the lower leg 11 is preferably additionally fixed by an additional receptacle 20, in particular in the region of the lower end or adjacent to the ankle 2, as in FIG Fig. 1 indicated.

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

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

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

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

Alternatively or additionally, the pivoting of the foot receptacle 6 about the movement axis 4 and / or the displacement in the displacement direction 19 can also take place 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.

The FIGS. 3 to 5 show a second embodiment of the proposed training machine 1. The second Ausrührungsform corresponds in function to at least substantially the first embodiment. The same or similar parts are provided with the same reference numerals, the previous versions and explanations apply correspondingly or in addition.

FIG. 3 shows the exercise machine 1 according to the second embodiment without foot or leg. The heel holder or cap 7 is here preferably both forward and backward and right and left adjustable.

The device 15 is designed differently in the second embodiment. In particular, an elastic element 18 is provided, which preferably engages in the region of the front foot on the foot receptacle 6 and in particular is mounted against the frame G.

FIG. 4 shows the exercise machine 1 with recorded foot 3 and fixed lower leg eleventh

In the second embodiment, the lower leg receptacle 10 and / or the foot receptacle 6 is height-adjustable,

FIG. 5 shows the exercise machine with recorded foot 3 from behind.

FIG. 6 shows in a fragmentary schematic representation of the foot 3 in a neutral position of the ankle 2. FIG. 7 shows in one too FIG. 6 Corresponding representation of the pronierten, externally raised foot 3. The foot 3 is thus raised about the axis of movement 4 in the ankle 2 upwards.

In general, the foot 3 or the foot receptacle 6, in particular the heel seat 7 also in Fußlängsrichtung - ie in the direction of the axis H in Fig. 2 be adjustable.

Individual features and aspects of the embodiment can also be arbitrarily combined with each other and / or used in other exercise machines.
