Description

The The invention relates to a training device, in particular for the rehabilitation after surgery, with a one in essence horizontally mounted shaft having holding device for stationary Determining the exercise device, with an actuator and with a load adjustment device having at least one load side Having arranged on the shaft lever arm, which in an unactuated Basic position of the training device with a room perpendicular includes an angle α and that by actuation the in operative connection with the Lasteinstellvorrichtung Actuation device of the training device in Circumferential direction of the shaft can be pivoted.

One Such training device is for example as so-called Pendulum leg press known. During an operation the pendulum leg press is by the pivoting of the load side Lever arm of the load adjustment device in the circumferential direction of the shaft the distance of the center of gravity of the load adjustment device with respect to the shaft changes, thereby increasing the torque the wave changed. This conditionally affects one Trainees on the actuator to be overcome Restoring force, which is a substantially sinusoidal changed. The power increases from a minimum to overcoming Force at α = 0 ° continuously to a maximum force to be overcome at α = 90 ° then from α = 90 ° to 180 ° again continuously to sink.

Out US-A-5106080 a training device is known in which the angle α in the unactuated basic position is substantially less than 10 °. It has two load-side lever arms, each lever arm has a designed as a footrest actuator. In such a training device, it is considered disadvantageous that the qualitative change in the force when operating the actuator can not be adjusted.

Another training device is off EP-A-0732128 known, in which the angle α is set before starting the training device and does not change when operating the actuator, because a weight is moved when operating the actuator along a fixed in the predetermined orientation lever arm.

Out In practice, mobile training devices are still rotatable stored pedals known that against a predetermined frictional force can be operated. Such a training device can also arranged in the bed of a bedridden patient and used by this patient for training purposes. Indeed are known from practice training equipment heavy and unwieldy, so they are hardly used.

task Accordingly, it is the object of the invention to propose a training device. which can also be used by bedridden patients and its training force, which opposes an operation acts, can be individually adjustable.

The Task is by an inventive training device the genus mentioned above, in which the training device a Lageeinstelleinrichtung, by means of which the angle α between the load-side lever arm of the load adjustment device and the space vertical in the unactivated basic position of the training device is determinable. This can be during an actuation process the actuator resulting change the restoring force can be specified. The angle α is freely adjustable between 0 ° and 180 °. The each resulting during an operation Change in the restoring force depends essentially from the respective current angular position α or Alignment of the lever arm relative to the vertical space from. A preferred starting position for the angle α between 0 ° and 90 °. For example, α = 0 °, resulting in a steady increase in the force to be applied to α = 90 ° leads. Furthermore, it is also possible to set α = 90 °, resulting in one at the beginning of one by the actuator forced panning action maximum restoring force and a steady decrease in the force to be expended in the course of actuation leads. Conceivable, however, are also settings with first increasing and then decreasing expended force, for example at α = 45 °. This way can be very easy For each user an individually adapted training force be set and specified.

From particular advantage here is that, especially in rehabilitation of weakened or damaged muscles Musculature is not only strengthened, but also by constantly changing the force to be expended, in their coordinative skills.

A Development of the invention provides that the Lageeinstelleinrichtung a concentrically arranged perpendicular to the shaft shim comprises and that the load-side lever arm in a predetermined angle α relative to the space vertical with the shim engageable is. The shim allows a very simple and reliable manual fixing of the lever arm in the desired angle α relative to the vertical space.

In a further development of the latter inventive concept, it proves to be advantageous if the shim of Lageeinstelleinrichtung on the load side comprises a first perforated ring segment on which the load-side lever arm can be fixed and released again. As a result, the angle α can be set in the unactuated basic position of the training device in a simple manner.

in principle can be the holes of the first ring gear segment be distributed arbitrarily on the shim. Under a hole rim segment This is an arrangement of holes along a Circumferential direction of the shaft understood, not necessarily all must be the same distance to the shaft. It proves to be beneficial if the holes of the first Perforated segment in the circumferential direction with respect to the shaft at an angle of 5 ° to 30 °, preferably between 5 ° to 20 °, particularly preferably between 5 ° to 15 ° are distributed to each other.

Around the load-side lever arm and the shim in a simple way to combine with each other, it proves to be advantageous if the Load-side lever arm at the height of the first hole circle of Shim a through opening, in particular a bore, by means of which the shim and the load-side lever arm by a plug connection, in particular by means of a pin, by means of a bolt or by means of a screw connection Manually fixed to each other and are detachable again.

at a development of the invention, it is provided that the angle α between the load-side lever arm and the verticals of the room can be adjusted from 0 ° to 180 ° is. This can change the expended Force when operating the actuator be set particularly variable.

in principle It is conceivable that, especially at an incipient rehabilitation of muscle the weight of the lever arm a weight load of Load adjustment device forms. However, it will be in most Use cases appropriate and for the therapy may be necessary that the load adjustment device in addition includes a fixable on the load-side lever arm weight part.

The Weight part can be connected as desired with the load-side lever arm For example, it may be perpendicular to a radial direction be attached to the shaft extending nose. In training However, the latter inventive idea proves to be advantageous if the weight part at the cross-sectional area Having the load-side lever arm adapted through-hole, by means of it on the load-side lever arm in the longitudinal direction the load-side lever arm is displaceable. If the opening the weight part complementary to the cross-sectional area the load-side lever arm is formed, forms the load-side lever arm a guide for the weight part.

About that In addition, it proves to be advantageous if the weight part of an opening transverse to the Aufschieberichtung and that the lever arm on a the shaft facing away from the direction transverse to the Aufschieberichtung a Having a plurality of openings, by means of which the weight part and the load-side lever arm by a plug connection, in particular by a pin, a bolt or a screw connection, can be fixed to each other. This allows the weight part without tools be moved on the load-side lever arm. This makes possible, that when operating the actuator expended force is variable. The further the weight part away from the shaft, the higher the maximum expended during an actuation process Power of the exerciser.

It It is also conceivable that the weight part in addition or alternatively to a manual adjustment motor can be displaced along the lever arm. Of the Lever can have a rotatably mounted spindle for this purpose, which is engaged with a threaded portion on the weight part and in a rotational movement of the spindle, a translational displacement caused by the weight part along the lever arm. The relocation of the Part of the weight can also counteract via a cable pull mechanism a spring force or against a likewise motor manipulatable Retaining rope can be effected.

at a motorized movable part of weight can during a training session automatically relocates the part by weight done, for example, depending on the already expired Exercise time or depending on one by means of sensors detected operating force the distance of the weight part from the shaft and, consequently, the for an actuation process to change the force to be applied.

The Actuator may be a handle, pedals or the like include. However, preference is given to a development of the invention, in which the actuating device is at least one user-side Lever and at least one arranged on the user-side lever arm Tread plate includes. The tread plate can either rigid or swivel be set or stored on the user-side lever arm.

In such a case, it proves to be advantageous if the position adjustment device can be brought into operative connection with the user-side lever arm. The user-side lever arm is preferably pivotable in the circumferential direction of the shaft on the shaft arranged. The shim may user side include a second hole segment on which the user-side lever arm is releasably fixed.

If the shim rotatably connected to the shaft leads an actuation of the actuator, for example counterclockwise to pivoting the load-side lever arm also counterclockwise.

At Place a rigid, or rotationally fixed operative connection between the User-side lever arm and the load-side lever arm can the two lever arms also via a gear, or a translation interact with each other. In this way it is possible that, for example, a greater deflection of the user-side lever arm a smaller deflection of the load-side lever arm causes, so for a larger actuation path a smaller force is required. By specifying appropriate Properties of the gearbox can be the one for use the training device required space required become.

in principle can the holes of the second perforated ring segment be distributed arbitrarily on the shim. It turns out However, as advantageous if the holes of the second perforated ring segment in the circumferential direction at an angle of 5 ° to 30 °, preferably 5 ° to 20 °, particularly preferably 5 ° to 15 ° are distributed to each other.

Around the user-side lever arm and the flange in a simple manner to combine with each other, it proves to be advantageous if the user-side lever arm at the level of the second perforated rim segment the shim has a through opening, by means of the dial and the user-side lever arm by a plug connection, in particular by means of a plug pin, one Bolzens or a screw connection can be fixed to each other.

Of the close the user-side lever arm and the verticals of the room an angle β with each other. In development of the invention it proves to be advantageous if the angle β between the user-side lever arm and the room vertical from 0 ° to 90 ° is adjustable.

About that In addition, it proves to be advantageous if the shim a stop for an unconfirmed basic position and / or a stop for a position of maximum deflection includes.

Further is provided in a development of the invention that the holding device has a U-shaped cross-section with which they are connected to a flat section of a piece of furniture, for example on the backrest a chair or a bed frame, and the training device is held against movement transverse to the space vertical.

After all it proves to be advantageous if the holding device in addition at least one fixing unit such as a screw clamp, a hook-and-loop fastener or the like.

Further Features, details and advantages of the invention will become apparent the appended claims and the drawings Presentation and subsequent description of a preferred embodiment the invention. In the drawing show:

The figures show a total with the reference numeral 2 characterized portable training device. The training device 2 has a through two U-shaped brackets 4 formed holding device 6 with which it is stationary fixed, for example, at a foot of a bed frame. The two U-shaped brackets 4 are at the open leg ends each one perpendicular to the brackets 4 horizontally extending cross strut 5 rigidly connected with each other. Between the two brackets 4 the holding device 6 is a wave 8th arranged horizontally and rotatable at both ends in the two brackets 4 stored. At the wave 8th is a dial 10 rotatably mounted.

To the shim 10 with a load-side lever arm 12 a load adjustment device 14 To connect, the shim has a first ring gear segment 16 on. The load-side lever arm 12 is rotatable on the shaft 8th stored. By means of an opening in the load-side lever arm 12 (not shown in the figures), the shim 10 and lever arm 12 through a plug connection 18 engaged with each other and fixed to each other, so that a pivoting movement of the shim 10 around the shaft 8th or with the wave 8th an equal directed and equal pivoting movement of the load-side lever arm 12 causes.

To the shim 10 with a user-side lever arm 20 an actuator 22 connect, the shim has a second perforated ring segment 2 on. By means of an opening in the user-side lever arm 20 (not shown in the figures) are the shim 10 and the user-side lever arm 20 engageable with each other and thereby fixed relative to each other. Starting from an unactuated basic position is by means of the actuator 22 via the user-side lever arm 20 a pivoting movement of the shim 10 causes counterclockwise, which also causes the Lasteinstellvorrichtung 14 over the load-side lever arm 12 is pivoted counterclockwise.

The load-side lever arm 12 closes with a vertical line an angle α and the user-side lever arm 20 includes an angle β with the space perpendicular. The user-side lever arm 20 , the load-side lever arm 12 and the dial 10 Together form a Lageeinstelleinrichtung 26 , By means of which the angles α and β can be set or specified.

1 shows the training device 2 in an unconfirmed basic position in the by the Lageeinstelleinrichtung 26 is set for α and β 0 °. In such case, the load-side lever arm run 12 and the user-side lever arm 20 each parallel to the space vertical.

In this arrangement, the training device 2 particularly compact, so that the training device, for example, if it is mounted on a bed frame, can remain there without disturbing it even if it is not used for training purposes.

The actuator 22 of the training device 2 according to 1 includes two user-side lever arms 20 , which pivot in the circumferential direction on the shaft 8th are stored, as well as a footboard 28 , by their actuation or

Deflection of the exerciser can train the muscles of the extremities. By providing two user-side lever arms 20 will increase the stability of the training device 2 elevated.

Via a plug connection 18 is one of the user-side lever arms 20 with the shim 10 connected by a fixing pin through an opening in the user-side lever arm 20 and a hole of the second ring gear segment 24 the shim 10 is plugged.

The embodiment according to 1 shows an embodiment of the training device 2 in which the load adjustment device 14 one part by weight 30 comprising that through an opening along the longitudinal direction of the load-side lever arm 12 is slidably fixed. For this purpose, the load-side lever arm 12 and the weight part 30 transverse to the longitudinal direction of the load-side lever arm 12 spaced from each other to a plurality of through openings into which a connector 18 Introducing is the weight part 30 on the lever arm 12 sets.

2 shows the training device 2 according to 1 in a rotated perspective view. It can be seen that the user-side lever arm 20 also via a plug connection 18 detachable with the shim 10 connected is.

Based on 3 and 4 becomes the functioning of the training device 2 explained in more detail.

3 shows the exercise machine 2 in an unconfirmed basic position. The training device 2 lies in such with a stop 32 for example, on a chair back or on a footboard of a bedstead. By means of Lageeinstelleinrichtung 26 became an angle α between the space vertical and the load-side lever arm 12 and an angle β between the space perpendicular and the user side lever arm 20 set. For this purpose, in each case the connector 18 solved and the user-side lever arm 20 or the load-side lever arm 12 around the shaft 8th pivoted until β or α have the desired size. Subsequently, the connectors were 18 back into the respective opening in the lever arms and in the first perforated rim segment 16 or in the second perforated ring segment 24 brought in.

About the angle α between the vertical space and the load-side lever arm 12 the force to be expended by a trainee is adjustable when the actuating device is actuated. With an angle α increasing from 0 ° to 90 °, the force that the exerciser exerts on the actuating device increases due to the increasing torque 22 must transfer to the load-side lever arm 12 continue to swivel. The force to be expended by the exerciser has a sinusoidal course, whereby it increases from α = 0 to 90 ° in order to decrease again from α = 90 ° to 180 °. In addition, the force the trainee has to expend is by the weight part 30 can be reduced and increased. A shifting of the weight part 30 towards the wave 8th Adds to reducing the force required. A moving away from the shaft 8th leads to an increase in the force required.

4 shows the training device 2 in an actuated position, wherein the unconfirmed Grundstel according to 3 is shown for illustrative purposes in dashed lines. In the illustrated setting of the angle α and β α reaches at maximum deflection just as an angle of 90 ° when the footboard 30 is actuated to its maximum possible end position, in which β = 0 °. As a result, with this adjustment, with reduction of β, an increase in the force to be applied is always effected by the exerciser.

5 shows the portable training device that is releasably fixed to a bed frame. The fact that the training device is detachably fixable, it is particularly suitable to be attached to a hospital bed for rehabilitation purposes.
