Description

"Training device with a frame and at least one arranged continuously rotatably movable crank"

The invention relates to a training device with a frame and at least one arranged on it continuously

Rotationally movable crank according to the generic term of the

Claim 1.

State of the art

Training devices of the type described in the introduction have already become known in various forms.

Such training devices are regularly in the

Rehabilitation of patients after accident or

illness-related operations or after a stroke.

Often also combined devices are used, in which a crank for an arm as well as a pair of legs

training person is provided.

On the arm crank there are usually handles for the hands and on the leg crank feet for the feet of a person exercising. Purpose and advantages of the invention

The ^' invention is based on the object to provide a training device of the type described in the introduction, the

advanced therapies possible.

This object is solved by the features of claims 1 and 4.

In the dependent claims advantageous and expedient developments of the invention are given.

The invention relates to a training device with a frame and at least one arranged on the frame continuously rotatably movable crank with a and rotatably mounted relative to the crank actuator for the hand of a person exercising, which is adapted to a moment in relation to a crank to exercise a rotation axis.

The essence of the invention lies in the fact that between the actuating element and the frame, a first

Coupling mechanism is arranged, which forces a reciprocating pivotal movement of the actuating element in a crankcase.

This measure has the following background:

Currently there are about 75,000 per year in Germany

Breast cancer new cases in women with an upward trend. Worldwide, this number is far exceeded.

In breast cancers are regularly at a

Operation few to all lymph nodes in the armpit area

In this area, the lymphatic vessels are damaged by radiation or chemotherapy in such a way that the lymph flow is inhibited or interrupted. An outflow and transport of lymphatic fluid from 2 to 5 Liters a day is vital for a functioning immune system.

The consequence of non-functioning outflow is a

Swelling of the arms, edema and inflammation in limbs.

It is possible to stimulate or restore this lymphatic flow by means of lymph drainage using massage or compression bandages.

For lymphatic drainage, there are no adjustment,

Preselection, programming, reproducing and / or measurable

Movements that could be caused by devices.

Here, the present invention provides a remedy. By an active or passive, for example, motor-assisted

Rotational movement of the crank arms and actuators, which include, for example, handles, cuffs, armrests or the like, the hands by the positive control of

Actuators on the first coupling mechanism in addition to the rotational movement recurrently moved into an angling. This targeted bending in a rotational movement of the wrist almost all skeletal muscles of the upper limbs are activated.

Through the targeted movement of many muscles and thus the

Muscle contractions, the lymphatic vessels are compressed and the lymphatic fluid in one direction. This direction is in turn through a variety of

Lymph vessel valves in the human body, which function as valves, given. The lymphatic fluid then follows the least resistance in the direction of the proximal widening lymphatic vessels. Overall, this activates the lymphatic system.

The invention has the following further advantages:

Affected persons can, if necessary, also several times if necessary Perform the lymphatic drainage daily, because they can use the therapy device with the appropriate technology, if necessary, at home and are therefore not dependent on appointments in practices.

The lymphatic drainage is reproducibly controlled by preselected movements over the first coupling mechanism.

The amount of movement can, for example, via a

adjustable coupling mechanism of mobility and the

Feel, for example, the pain threshold of the patient be adjusted continuously.

In an advantageous embodiment of the invention, the actuating element comprises a handle for a hand of a

exercising person. Also conceivable is a cuff

and / or arm cup optionally in addition, with which it is possible for a person exercising, with a

Actuator to connect.

To extended movement possibilities, in particular one

To obtain wrists, it is also proposed that the handle on the actuating element relative to

remaining actuator is pivotally mounted to perform a pivotal movement during a crank. This is in addition to the forced control of the

Actuator created a further movement option, which additionally positively affects the lymphatic system.

In particular, in the case when a handle rotatable or

pivotally mounted with respect to the rest of the actuating element, another important aspect of the invention is that between the pivotally mounted on the actuating element handle and the crank a second

Coupling mechanism is provided which a reciprocating pivotal movement of the handle during a crank movement

pretends relative to the moving element. In combination with the positively controlled reciprocating motion of the actuator with respect to the crank arm can thus two independent Movements are transmitted to a wrist and thus to the muscle groups of an arm during a crank movement, depending on the position of the handle

overlap differently.

In a preferred embodiment of the invention

proposed that an axis of the handle with respect to the remaining actuator is adjustable. This means to be able to set a fixed predetermined basic position of the handle with respect to the rest of the actuator, regardless of the fact that the handle is optionally additionally rotatable or pivotally mounted on the actuating element with respect to the rest of the actuator.

It is conceivable, for example, an arrangement of a handle in a basic position approximately parallel to the pivot axis of the actuating element. Another possibility is to arrange the axis of the handle in a region of a perpendicular to the axis of rotation of the actuating element. In this position in positively controlled rotational movement of the handle in the actuator, a large amount of movement in the wrist can be realized.

In a particularly preferred embodiment of the invention, the first coupling mechanism comprises, for example, a coupling linkage connected via joints. However, the coupling mechanism can also have a Bowden cable and / or a

Rack and pinion gear and / or a belt drive (eg

Timing belt) may be additionally realized.

Accordingly, the second coupling mechanism can be constructed.

In order for the handle to pivot in the

Actuating element is proposed in a further preferred embodiment of the invention that between the crank and actuator an eccentric element is present, wherein the eccentric element is part of the second coupling mechanism. The type of wrist or arm movement can of course be performed not only on a single wrist, but in a two-sided crank on both wrists of the hands of a person exercising. For this purpose, it is provided with a suitably constructed crank pair

Use actuators for the hands of a person exercising.

In a particularly preferred embodiment of the invention, an electric motor is provided for the drive for the crank. In this way, a passive training can be

realize in which a person exercising

just hold on to the handles and otherwise the motor will transfer the motion to the muscular system. With a view to improving the outflow of

Lymphatic fluid can be a passive training advantageous because then the muscles are not under tension, but is relatively loose, which is beneficial to the

Lymphatic vessels can affect because no tense musculature presses together lymphatic channels and thus blocks or at least narrows.

Description of the embodiments

An embodiment of the invention will be described below with reference to several drawings, indicating further advantages and

Details explained in more detail. Show it

Figure la a training device for leg and

Pairs of arms in a perspective view,

FIG. 1b shows a top section of the training device according to FIG. 1a in a side view,

Figure 2 shows a crank arm of the training device in a perspective view and

Figure 3 shows the crank arm of Figure 1 in a partial cut top view.

In Figure la a rainingsgerät 1 with a pair of crank 2 with foot shells 3 for a pair of legs and a pair of crank 4 with actuators 5 for a pair of arms of a person exercising shown.

The crank pair 2 for the legs and the crank pair 4 for the arms can each be braked or driven via a separate drive 6, 7. In the braked case, a desired actuation torque can be made available to a person exercising, whereas in the driven case a exercising person can be "passively" move.

The training device 1 comprises a control unit 8 and a base frame 9, on which the drives 6, 7 with the pair of cranks 2, 4 and the control unit 8 is arranged. The

Actuators 5 are each rotatably mounted on a crank arm 10 of the crank pair 4, so that the

Actuator can move with the crank arm and at the same time can pivot relative thereto. The

Actuators 5 are each connected via a coupling linkage 11 with the base frame 9, whereby during a rotation of the crank arm 10 each actuator 5 through the

Koppelgestänge 11 enforced in one revolution performs a reciprocating motion that leads to a kinking of the wrist according to the reciprocating motion when a person exercising on a handle 12 of the

Actuator 5 stops. This reciprocation causes contraction and stretching of the muscles in the arm, which stimulates the lymphatic system and activates it to a desired level

Lymphatic system leads, with an improved outflow of

Lymphatic fluid.

The first coupling mechanism, which is present in FIG. 1 in the form of a coupling linkage 11, is preferably adjustable, so that the extent of the reciprocating movement can be adapted to the needs of a person exercising. in the

present case are hinged together Rod elements 13, 14 between frame and

Actuators 5 adjustable in length, so that thereby a reduction or increase in the reciprocating motion of the actuators 5 can be achieved. For this purpose, see in each case locking screws 13b on sleeves 13a, in which the rod elements 13, 14 are inserted and fixed.

The rod elements 13 and 14 are articulated on a stand-like structure 14a with an angle element 14b for setting a lateral position. The angle element 14b

in turn, this is slidably received in a receiving piece 14c, which is connected to a transverse column 14d of the frame. 9

is mounted.

The handle 12 of the actuators 5 can be adjusted in its axis 12a with respect to the actuator 5 in a basic position, preferably about a pivot axis 15 perpendicular to a rotation axis 16 of the actuating element 5. The adjustment can be made via a locking pin 36.

In addition to the imposed back and forth movement of the

Actuators 5 are also the handles 12 back and forth about a pivot axis 15a pivoted on the respective

Actuator 5 recorded (see in particular Figures lb, 2 and 3).

The axes 15 and 15a fall in the present

Embodiment together.

This additional superimposed reciprocating motion is provided by another second coupling mechanism

Coupling linkage 17 causes. The coupling linkage 17 is mounted between the actuating element 5 and an eccentric 18, which is penetrated by a pin 19, through which the

Actuator 5 is pivotally connected to the crank 10. For this purpose, the pin 19 is inserted with its crank-side end in a pivot bearing 20 in the crank arm 10, whereas the other side fixed to the actuating element 5 at a Recording disc 21 is connected to the clamping ring 21a. Of the

Eccentric 18 is divided into two parts. An inner ring or inner ring 22 with receiving opening 22a for the pin 19 is fixedly connected to the crank arm 10 and is penetrated at the receiving opening 22a from the pin 19. The receiving opening 22a is

eccentrically arranged on the inner ring 22. On the inner ring 22, an outer ring 24 is rotatably supported via a ball bearing 23. On the outer ring 24, a mounting arm 25 is fixedly mounted with ball joint 26. About the ball joint 26 is the

Coupling linkage 17 coupled to the mounting arm 25 on a first side of the coupling linkage 17, whereas the other side of the linkage 17 is connected via a ball joint 26a with an arm 27 which is fixedly mounted on a pivot member 28. With the pivot member 28 of the pivots

Handle 12.

The pivot member 28, and thus the coupling mechanism for the handle, may preferably be disengaged by a detent pin 27a for which there is a decoupled or coupled position for the pivot member 28 on a dial 27b.

The coupling leads to a reciprocation of the

Handle 12 about the pivot axis 15a, caused by the eccentric 18 and acts as follows:

Upon rotation of the crank arm 10 is a

Actuator 5 via the coupling linkage 11 at a

Anlenkstelle 29 (see Figure 3) held so that the actuator 5 can not easily rotate with the crank arm 10, as forced by the coupling linkage 11 is a reciprocating movement with the result of tipping and re-erecting the handle 12 in the example shown Handle position causes.

At the same time moves the outer ring 24 of the eccentric 18 on the eccentrically mounted inner ring 22, with the result that the mounting arm 25 a pointer movement in one

executes predetermined angular extent. This leads to that Coupling rod 17 performs a rocking motion about a bearing 30 on the actuating element 5, which has a swinging back and forth of the pivot member 28 and thus the handle 12 with respect to the remaining actuator 5 result. The amount of swinging back and forth can be done by adjusting the articulation points of rod members 31, 32, 33.

For example, the arm 27 has different bearing openings 34 (see FIG. 2) for mounting the arm 31. In addition, on the other side of the arm 31 it can be mounted on the rod element 32 in different bearing openings 35. In addition, if necessary, the length of the rod elements 31, 32, 33 or the position of the bearing 30 can be adjusted in order to adapt the "cybernetics" of the coupling rod 17 as desired to a person exercising.

As a result, in one revolution, tilting of the handle 12 is obtained to the left and to the right while the handle 12 is tilted back and forth. Thereby, a tilting movement with torsion is transmitted to the wrist of a exercising person, thereby creating a variety of muscles in the arm of a exercising person be addressed, which in turn mobilize the lymphatic system.

If the forced movement of the eccentric bearing on the locking pin 27 a is turned off, is in horizontally positioned

Handle 12, which is adjustable over the locking pin 36, the wrist up (Dorsalextension) and down

(Palmar flexion) moves. When the handle is positioned vertically, the movement of the ulnar abduction and the radial abduction of the wrist are achieved. There are also various hybrid forms and intermediate positions ZSi, ZS2 (not in the figures

shown), ZS3 (not shown in the figures), ZS _X from horizontal to vertical position of the handle 12 via the locking pin 36 possible. As a result, different wrist movements can be realized simultaneously. Reference number:
