Description

The invention relates to a training device for active movement training of the upper and / or lower extremities with at least two training arms, which are preferably pivotable in opposite directions of rotation, and with a rod-shaped drive element which, depending on the direction of rotation exerted on at least one of the training arms rotational driving force against the Resetting or resistance force of a force or resistance transmitter in one or the other rod longitudinal direction is movable.

From the DE 10 2005 021 014 B3 One already knows a training device of the type mentioned, which is intended for active movement training in particular the upper extremities. The previously known training device has for this purpose two training arms, which are preferably in opposite directions against the Rückstell- the resistance force of a force or resistance encoder swivel. The previously known exercise device has a rod-shaped drive element which is movable in at least one rod longitudinal direction, depending on the direction of rotation of a rotational drive force exerted on at least one of the training arms against the restoring or resisting force of the force or resistance transmitter. In order to counteract the drive element a restoring or resisting force, the previously known training device on an electro-rheological or magneto-rheological resistance encoder, which serves as a double-acting force or resistance transmitter and its restoring or resistive force by current or voltage changes of him applied current can be changed.

It has also been created various exercise equipment that have a weight tower as a force or resistance transmitter in which exert a determinable compilation of exercise weights the restoring or resisting force. In this case, the selected number of training weights against gravity by opposing rotational movements on the training arms repeatedly raised from a rest position to a training position. Since the training weights can only be raised and because the training weights can thus only act as unilaterally effective force or resistance transmitters, the training arms are only rotatable in one direction from a rest position to a training position, which is why these prior training devices, for example, only as a breast stabilizer (Butterfly) or may be formed as a posture stabilizer (press back) or in the case of a combination device require a respective rotated seat position of the user.

There is therefore in particular the task of creating a training device of the type mentioned, which allow a rotational movement of the training arms either in the one or the other direction without a changed seating position of the user, without therefore a complex and expensive force or Resistivity would be required.

The achievement of this object is in the training device of the type mentioned in particular that the rod-shaped drive element via a gearbox with the force or resistance encoder is in drive connection, that the drive element arranged between at least two drive wheels of the gearbox and relative to these transverse to its longitudinal bar between a first and a second drive position is veschiebbar in which drive positions the drive element is either in drive connection with one or with the other drive wheel, that the drive wheels via a chain, a cable or the like first flexible connection means are connected, and in that a longitudinal movement of the drive element can be converted from a rest position into a training position into a rotational movement of the drive wheel which is in drive connection with it in such a way that the first V held on the drive wheels is displaced binding agent against the force acting on the first connecting means restoring or resisting force of the force or resistance encoder on the drive wheel is wound.

In the training device according to the invention, the rod-shaped drive element, which is movable in both the one and in the other rod longitudinal direction, via a change gear with the force or resistance encoder in drive connection. The rod-shaped drive element is arranged between two drive wheels of the change gear and relative to these transversely to its rod longitudinal direction between a first and a second drive position displaceable, in which drive positions the drive element is either in drive connection with one or with the other drive wheel. In order to move the drive element or the drive wheels transversely to the rod longitudinal direction, either the drive element or the drive wheels or both types of drive means in the exercise device according to the invention can be guided displaceably. The drive wheels are connected via a chain, a rope or the like first flexible connecting means. In this case, a longitudinal movement of the drive element can be converted from a rest position to a training position in such a rotational movement of the drive wheel drivingly connected to it that the first connecting means connected to the drive wheels against the on the the first connection means acting restoring force of the force or resistance sensor is wound up. If this drive wheel is rotated by a longitudinal movement of the drive element in a rod longitudinal direction, for example in a clockwise direction from its rest position to the training position that the first connecting means is thereby wound in the drive wheel, the drive element for longitudinal movement in the other rod longitudinal direction be moved into the other drive position, in which the drive element is now brought into engagement with the other drive wheel, which other drive wheel wound by a rotational movement taking place in the counterclockwise direction, the first connecting means. The change gear of the exercise device according to the invention thus sets the choice or alternately occurring in opposite rod longitudinal directions longitudinal movements of the drive element in longitudinal movements at the force or resistance encoder, which in contrast have only one effective direction. Since in the exercise device according to the invention thus an effective in opposite directions and thus double-acting force or resistance encoder is not required and thus thus in only one effective direction effective and thus single-acting force or resistance encoder is sufficient, can also be simple, inexpensive and störunanfällige force or resistance transmitter, such as weight storms, resorted to, without thereby the versatility of the training device according to the invention, for example, as a chest and posture stabilizer without awkward seat changes of the user is impaired. The training device according to the invention can also be configured as an abduction or adduction trainer.

In the training device according to the invention can be used on single-acting force or resistance transmitter, such as hydraulic or pneumatic cylinders. A particularly störunanfällige and low maintenance embodiment according to the invention, however, provides that the force or resistance transmitter has at least one training weight that can be raised from a rest position against gravity in a training position.

In order to accomplish the drive connection between the change gear on the one hand and the force or resistance transmitter on the other hand, it is expedient if the connecting means is guided in its guided between the drive wheels area at least a first deflection, at which first deflection the at least one training weight of force or resistance transmitter is held.

A simple embodiment according to the invention may consist in that the drive wheels are designed as friction wheels, and that in each case the stationary with the drive element in drive connection drive wheel during a longitudinal movement of the drive element frictionally rolls on it.

However, in order to prevent slippage between the drive element on the one hand and the driving drive connected therewith in drive connection even after a long period of operation and wear, it is advantageous if the drive wheels are designed as gears, of which either one or the other drive wheel with the on opposite longitudinal sides formed as a rack drive element meshes.

In order to secure each in the rest position with the drive element disengaged drive wheel in its rest position, it is advantageous if each of the drive wheels with the drive element not in drive connection drive wheel is blocked in the rest position and / or secured.

In order to accomplish a relative movement of the drive element with respect to the drive wheels from one to the other drive position, the drive element, with him selectively or alternately engageable drive wheels or both drive means (drive element and drive wheels) may be guided displaceably in the exercise device according to the invention , However, a structurally simple to design and therefore preferred embodiment according to the invention provides that the drive wheels are held on a transverse to the bar longitudinal direction of the drive element slidably guided slide.

In order to bring the change gear to a zero position, it may be advantageous if the drive element is in a rest or intermediate position of the transmission with the drive wheels out of engagement.

So that the user can operate the change gear and change the pivoting direction of his training movements without having to take his hands off the training arms of the training device according to the invention, it is advantageous if the training device for relative displacement of the drive element on the one hand and drive wheels on the other hand, at least one, preferably designed as a pedal levers Has.

A preferred embodiment according to the invention, which the present invention advantageously with the DE 10 2005 021 014 B3 the patent application previously known to the Applicant combined, provides that the training arms are connected by two cables, chains or the like flexible second and third connecting means, that these second and third connecting means are guided on opposite sides of a second deflection held on the drive element, that the end regions of each of the second and third Connecting means in the training arms in opposite directions of rotation are wound up and unwound and that while held in the region of a pivot axis end portions of the second and third connecting means are such or aufwickelbar that by pivotal movement of the associated training arm of the end portion of a connecting means up and the end portion of the other connection means is unwound.

Further developments according to the invention will become apparent from the following description taken in conjunction with the drawings and the claims. The invention will be described in more detail below with reference to a preferred embodiment.

The single FIGURE shows a training device which can be used as a thorax and posture stabilizer in a schematic representation, which exercise device has two training arms which are preferably pivotable in opposing directions of rotation, which selectively or alternately in the one or the other direction of rotation against the restoring or resisting force of a weight tower are movable.

The training device shown here only schematically 1 is intended for exercise training of the arms of a user. The training device 1 has two training arms 2 . 3 , which are manually grasped by the user and can preferably be pivoted in opposite directions of rotation Pf1, Pf1 'or Pf2, Pf2'. For example, if the user moves his arms toward one another in front of the chest, he has to exercise one 2 to be pivoted clockwise while the other training arm 3 to turn counterclockwise. By contrast, when the user moves his arms apart from his chest, he is now a training arm 2 to pivot counterclockwise while the other training arm 3 must be pivoted clockwise.

These opposing pivotal movements on the training arms 2 . 3 be on a rod-shaped drive element 4 transmitted, depending on the direction of rotation of at least one of the training arms 2 . 3 applied rotational drive force in one or the other rod longitudinal direction Pf3 or Pf4 is movable. In this case, the rod-shaped drive element via a gear change with a force or resistance encoder in drive connection. The rod-shaped drive element 4 is to between two drive wheels 5 . 6 the change-speed gear arranged and displaceable relative to these transversely to its rod longitudinal direction between a first and a second drive position, in which drive positions the drive element 4 either with one or the other drive wheel 5 respectively. 6 is in drive connection. To the drive element 4 or the drive wheels 5 . 6 can be moved transversely to the rod longitudinal direction, either the drive element 4 or the drive wheels 5 . 6 or both types of drive means 4 respectively. 5 . 6 in the training device 1 be guided slidably.

The drive wheels 5 . 6 are via a chain, a rope or the like first flexible connection means 7 connected. In this case, a longitudinal movement of the drive element 4 in a rotational movement of the drive wheel in drive connection with it 5 or 6 be converted from a rest position to a training position that on the drive wheels 5 . 6 held first connecting means 7 against the on the first connecting means 7 acting restoring force of the force or resistance transmitter on the drive wheel 5 or 6 is windable. Will this drive wheel 5 or 6 by a longitudinal movement of the drive element 4 in the one rod longitudinal direction Pf3 or Pf4, for example, in a clockwise direction from its rest position to the training position rotated such that the first connecting means 7 thereby on this drive wheel 5 or 6 is wound, the drive element 4 be moved for longitudinal movement in the other rod longitudinal direction Pf4 or Pf3 in the other drive position, in which the drive element 4 now with the other drive wheel 6 respectively. 5 is engaged, which other drive wheel 5 or 6 by a counterclockwise rotational movement, the first connecting means 7 wrapped up in itself.

The change gear of the training device 1 thus sets the choice or alternately required in opposite rod longitudinal directions Pf3 or Pf4 longitudinal movements of the drive element 4 in longitudinal movements at the force or resistance transmitter, which in contrast has only one effective direction. As with the training device shown here 1 Thus, an effective in opposite directions and thus double-acting force or resistance encoder is not required, and thus a sufficient in only one effective direction and thus single-acting force or resistance transmitter is sufficient, can also be simple, inexpensive and störunanfällige force or Resistor can be resorted to, without thereby the versatility of the training device 1 , for example, as a breast and as a stabilizer without cumbersome seat changes of the user, is impaired.

The force or resistance transmitter of the training device shown here 1 has at least one training weight 8th on, which can be raised from a rest position against gravity in a training position. In this case, the first connection means 7 in his between the drive wheels 5 . 6 guided area around a first diversion 9 guided, at which deflection 9 that at least a training weight 8th held the force or resistance transmitter.

The training weight 8th designed here as a weight storm force or resistance transmitter is a rod-shaped sword with the deflection 9 connected. The at least one training weight has a preferably central through-opening, which passes through the sword. The sword of the force or resistance transmitter can also enforce the passage openings of several training weights, so that only one of the training weights must preferably be connected to the sword via a plug connection to simultaneously secure the overlying training weights on the sword. That at least a training weight 8th is liftable against gravity from a rest position to a training position.

In the training device shown here 1 are the drive wheels 5 . 6 designed as gears, of which either one or the other drive wheel 5 . 6 with the formed on opposite longitudinal sides as a rack drive element 4 combs. When lifting the training weights each with the drive element 4 drive wheel not in drive connection 5 or 6 to block in the rest position, this drive wheel engages 5 or 6 in its rest position in a relative to the training device 1 fixed ratchet teeth 10 one.

In the training device shown here 1 are the drive wheels 5 . 6 on a transverse to the rod longitudinal direction of the drive element 4 slidably guided sled 11 held. This sled 11 can transverse to the rod longitudinal direction of the drive element 4 be moved back and forth so that either the one drive wheel 5 or the other drive wheel 6 with the drive element designed as a rack 4 combs. For relative displacement of drive element 4 on the one hand and drive wheels 5 . 6 on the other hand and to the displacement of the carriage 11 is on the training device 1 a lever not shown here provided, which is preferably designed as a pedal.

With the help of the change gear, the restoring or resisting force of the force or resistance transmitter designed here as a weight tower is such on the training arms 2 . 3 transferable that these training arms 2 . 3 can be pivoted against the restoring or resisting force of the force or resistance sensor preferably in opposite directions of rotation Pf1, Pf1 'or Pf2, Pf2'. The training arms 2 . 3 are flexible via two bands, straps, chains or the like second and third connecting means 12 . 13 connected with each other. These connecting means 12 . 13 , which are designed here as wire ropes, are on opposite sides of a second deflection 14 guided on the rod-shaped drive element 4 is held.

The end portions of each connecting means 12 . 13 are in the range of swivel axes 15 . 16 the training arms 2 . 3 can be wound up and unwound in opposite directions. These are in the range of a pivot axis 15 . 16 held end portions of the connecting means 12 . 13 such on or unwound that by a pivoting movement of the associated training arm 2 . 3 the end region of the one connecting means 12 . 13 up and the end of the other connection means 13 . 12 is handled. In this way it is ensured that the pivoting movement of the training arms 2 . 3 regardless of their direction of rotation always over one of the connecting means 12 . 13 takes place against the restoring or resisting force of the force or resistance transmitter, wherein the training arms 2 . 3 can be moved independently of each other according to the individual power relations of the user, although the training arms 2 . 3 of the training device 1 only a common force or resistance transmitter 4 assigned.

The between the training arms 2 . 3 on the one hand and the second diversion 14 on the other hand arranged subregions 12a . 12b respectively. 13a . 13b the connecting means 12 . 13 , each have a third diversion 17 . 18 . 19 and 20 guided on the, the contact area between the connecting means 12 . 13 and the second diversion 14 arranged away from each other. The connecting means 12 . 13 are so around the second and third deflections 14 respectively. 17 . 18 . 19 and 20 that led the connecting means 12 . 13 have an approximately W-shaped and mutually mirrored leadership course.

For winding and unwinding of the connecting means 12 . 13 are the training arms 2 . 3 with winding wheels 21 . 22 rotatably connected. Such winding wheels are also on the gears 5 . 6 rotatably held, there too, the first means of connection 7 to be able to wind up. The winding wheels, which may be formed in chain-like connecting means as sprockets, here are disc-shaped and coaxial with the pivot axes of the training arms 2 . 3 or the drive wheels 5 . 6 arranged.

The diversions 9 . 14 and 17 to 20 can be designed as deflection rollers, which are rotatably mounted. It has the drive element 4 provided diversion 14 two, each one of the connecting means 12 . 13 associated and independently rotatably mounted pulleys.

The training device shown here 1 can be used both as a breast stabilizer (butterfly) or as a stabilizer (press back), without the user would have to change the occupied sitting or training position.
