Description

The invention relates to a device for foot muscle training, with at least one base plate for receiving a foot to be trained.

A training device of the aforementioned type is from the document DE 201 03 657 U1 known. This known training device is used in particular for training the feet and / or the feet near the limbs. It has a base plate with at least one receiving area arranged thereon for a foot to be trained. At the rear end of the foot receiving area a heel support point is provided on the upper side of the base plate. At the front end portion of the foot receiving portion, a support against the base plate supported abutment for the front foot area is provided, which comes in the use position on the upper side of the front foot area to the plant. The abutment is designed as an elastic tensile member which is arranged transversely to the extension direction of the foot receiving portion and connected on both sides of the Fußaufnahmebereiches at least one attachment point with the base plate. During training, the toes and / or the forefoot are alternately raised against the restoring force of the elastic tension element from the rest position and then lowered back into it. The well-known training device thus allows a dynamic training of the muscles, whereby this is strengthened. There is a need for a training device that can mitigate sagging, spreading and kinking foot complaints. For the known training device is apparently neither intended nor suitable.

The object of the invention is to improve a device of the type mentioned so that it allows a simple structure to mitigate sinking, spreading and Knickfußbeschwerden.

To solve this problem, a device of the type mentioned is inventively characterized in that the base plate is divided into a fixed part which can be placed on the ground and in a movable part relative to the fixed part, with a elastic restoring force can be acted upon or acted upon in the direction away from the ground and can be pivoted by foot pressure in the direction of the ground about a pivot axis. If a foot to be trained on the base plate is arranged so that the big toe bale comprehensive part of the sole of the foot on the movable part and the remaining part of the sole of the foot is arranged on the fixed part, can be with the big toe ball of the movable part in the manner of a spring rocker against pivot the restoring force towards the floor. As a result, the foot muscles are trained so that lowering, spreading and kink foot complaints can be alleviated.

In this way the training result can be further optimized.

In a further embodiment of the device according to the invention, the movable part of the base plate is not loaded by a foot state on a first pivot stop and forms an angle with the fixed part of the base plate, which is in a range of 10 ° to 45 °. It is possible to further optimize the training course and the training result by selecting a corresponding start position for the moving part.

In a further embodiment of the device according to the invention, the movable part of the base plate in a loaded by a foot state on a second pivot stop in abutment to form below the horizontal with the fixed part of the base plate an angle which is in a range of 10 ° to 25 °. In this way, the end position for the pivoting movement of the movable part can be determined for an optimal training course and an optimal training result.

In further embodiments of the invention, the first and / or the second pivot stop is adjustable. In this way, the training course and the training result can be adapted even more closely to the conditions of a foot to be trained.

In a further embodiment of the device according to the invention at least one spring between the movable and the fixed part of the base plate is arranged to produce the elastic restoring force, the spring force is selectable or adjustable. This provides another way to optimize training history and training result.

In a further embodiment of the device according to the invention, this has an electrical indication of the pivoting state of the movable part of the base plate and / or for the force exerted by the foot on the moving part of the base. In this way, the training process can be easily monitored optically.

In a further embodiment of the device according to the invention, a right standing plate and a mirror-image formed left standing plate are arranged in mirror image side by side and fixed or adjustable by a connecting part connected to each other.

a second embodiment of the exercise device according to the invention in a perspective view obliquely from above.

In Fig. 1 a preferred embodiment of a training device according to the invention is shown in a perspective view obliquely from above and indicated generally at 10. The exercise device 10 is in the Fig. 1 - 4th shown unloaded. The device 10 has two pedestal plates 12 and 14, which are connected together by a connecting part 16 integral with a pedestal. The connecting part 16 could also be a profiled rail 16 ', which extends over the length of a generally designated 10' and in Fig. 9 shown device and with the two base plates 12 'and 14' are releasably and adjustably connected. The device 10 'after Fig. 9 has compared to the device 10 after the Fig. 1-8 the advantage that the mutual distance of the left and the right base plate 12 'and 14' is adjustable. But this is not necessary to achieve optimal training success. The following embodiments therefore mainly relate to the preferred embodiment of the device 10 according to the Fig. 1-8 ,

The left base plate 12 and the right base plate 14, which are rigidly connected to each other by the connecting part 16, form in a plan view, as in Fig. 3 is shown, a substantially U-shaped part. Each stand plate 12, 14 is subdivided into a bottom-mounted fixed part 12a, 14a, respectively, and a part 12b, 14b movable relative to the fixed part, which is acted upon by an elastic restoring force in the direction away from the ground and by foot pressure in the direction of Floor is pivotable about a pivot axis 12c and 14c.

On each fixed part 12a, 14a of the pedestal plates 12 and 14, a lateral abutment 18 or 20 is arranged for the foot such that the abutment 18 and 20 with the pivot axis 12c and 14c of the movable member 12b and 14b at an angle α, which is in a range of substantially -15 ° to substantially + 90 °. Each lateral abutment 18, 20 is adjustable with respect to the pivot axis 12c, 14c so that a left or right foot to be trained with the heel is applied to the fixed part 12a of the left standing plate 12 and the fixed part 14a of the right standing plate, respectively 14 and at least with the big toe ball on the movable part 12b, 14b of the base plate 12 and 14 can be placed, and vice versa. Such a foot position is indicated by the two in Fig. 7 Dashed lines indicated footprints illustrated. In the implied reverse case, the moving parts 12b, 14b would be depressed by the heel rather than the big toe bale, which would make achieving optimum exercise results more difficult when it comes to lowering, spreading and kinking foot complaints on the other hand, would improve the training result when it comes to relieving other foot complaints. The adjustment of the lateral abutments 18, 20 with respect to the pivot axis 12 c and 14 c is effected by means of an eccentric 22 and 24 in the second embodiment Fig. 9 each lateral abutment 18 ', 20' in a protruding leg 18a ', 18b' has a slot through which a fastening screw extends, as shown at 19 'and 21', respectively.

The lateral abutments 18, 20 are each provided with a substantially rectangular stop 26 or 28 as a support for the heel of the left or right foot.

Further, the lateral abutments 18, 20 are adjustable so that a foot to be trained on the base plate 12 and 14 can be aligned so that the course of the pivot axis 12 c and 14 c (or between the fixed part 12 a and the movable part 12 b or between the fixed part 14a and the movable part 14b existing gap 12d and 14d, in Fig. 3 indicated) extends substantially from the inside of the heel out from under the foot to an area under the second to fourth toe, as is the two footprints in Fig. 7 also illustrate.

On each of the two abutments 18, 20, a block 60 or 62 is slidably disposed. For displacement of each block with respect to its abutment is an adjusting screw 64 and 66. In each block 60, 62, a switch (not visible) is arranged, which is actuated by an actuating plate 68 and 70, respectively. The actuation of the actuator plates 68, 70 takes place in each case with the ankle. The switches are associated with lamps 72 and 74, respectively. These lamps indicate whether the foot concerned has the correct basic position to the exercise device 10. The aforementioned switches serve as a control switch for the correct foot position. The lighting up of the lamps 72 and 74 indicates that effective training can be commenced. By changing the position of the blocks 60, 62 by means of the adjusting screws 64 and 66, it is possible to facilitate different people individually tailored Fußmuskel- and Fußdynamik training.

The moving parts 12b, 14b of the pedestal plates 12 and 14 are in not loaded by a foot state each on a first pivot stop 30 and 32 and form above the horizontal with the fixed part 12a and 14a of the pedestal plates 12 and 14 a Angle β, which is in a range of 10 ° to 45 °, as in Fig. 4 is shown. To generate the elastic restoring force which holds the movable part 12b, 14b on the stopper 30 or 32, a spring 34 or 36 between the movable part 12b and 14b and the fixed part 12a and 14a of the base plate 12 and 14 are arranged, the spring force is selectable or adjustable. In the exemplary embodiment shown, the springs 34, 36 are arranged between a leg 38 or 42 projecting downwardly on the movable part 12b or 14b of the base plate 11 and 14 on the one hand and a retaining bolt 42 or 44 respectively attached to the connecting part 16.

In the device 10 'after Fig. 9 the elastic restoring force of the movable parts 12b 'and 14b' is not generated by tension springs as in the device 10, but each by a torsion spring (in Fig. 9 not visible).

The movable part 12b, 14b of the base plate 12 and 14, respectively, can be brought into abutment by a foot on a second pivot stop 46 and 48, respectively, below the horizontal with the fixed part 12a and 14a of the base plate 12 and 14, respectively to form an angle γ ranging from 10 ° to 250 ° as shown in FIG Fig. 8 is indicated. The first and the second pivot stop 30, 32 and 46, 48 may each be adjustable, which is not shown in detail in the drawings.

In the apparatus 10, the left standing plate 12 and the mirror-image formed right standing plate 14 are arranged in mirror image side by side and firmly connected to each other by the connecting part 16, as shown in the Fig. 1 - 8 is shown, or adjustably connected to each other as it is in Fig. 9 is shown.

The apparatus 10 has an electric display 50a and 50b for the pivotal state of the movable part 14a and 14b of the base plate 12 and 14, respectively, and an electric display 52a and 52b for the foot with the movable part 12b and 14b of the base plate, respectively 12 and 14 applied force, as in Fig. 7 is shown. In the simpler embodiment, the in Fig. 9 is shown, these electrical indicators are not present.

In the following, the operation of the device 10 using the example of the left base plate 12 and with reference to the illustration in Fig. 3 described. The use of the right base plate 14 is analogous and need not be described in detail in addition.

A person wishing to exercise their foot muscles stands with his left foot on the left standing board 12 without pressing down the movable part 12b of the standing board 12. The movable part 12b of the base plate 12 thus initially remains in the in Fig. 4 shown position. The foot becomes laterally tight against the lateral abutment 18 and whole pushed back to the support on the stop 26. The foot outside should be in full contact with the lateral stop 18. It is now checked whether the gap 12d or the pivot axis 12c between the fixed part 12a and the movable part 12b is below the gap between the third and fourth toe and whether the foot at the heel lies completely on the base plate 12. The exercising person now tries to slowly and as far as possible push down the movable part 12 b with the big toe ball, without loosening the foot from the lateral stop 18. Then slowly raise the big toe ball again until the moving part 12b moves to the starting position Fig. 4 has returned. If now the foot is still fully flush with its outer side against the lateral stop 18, the movable part 12b is slowly pressed down again with the big toe ball. This exercise is repeated several times.

Similarly, the right foot is trained on the right footboard 14, simultaneously or alternately with the left foot.
