Description

The invention relates to a training or therapy device for performing sports or therapeutic exercises. In particular, the invention relates to a training or therapy device of the type described, which has at least one of the exercising person as a user with their extremities engageable actuator that is movable by the user against a force applied by the exerciser counter force.

There is a variety of exercise equipment is known in which a counterforce is provided by weights, or where an opposing force is generated by an electric motor against the applied by the exerciser power. Such a training device is for example from the EP 1 803 489 A1 known.

In the usual exercise equipment, such as one of the DE 199 56 945 C2 described training device, it is not possible to perform opposing movements such as adduction and abduction on the same device, which is why it is customary to provide different devices for the different exercises or to rebuild them as needed.

From the DE 20 2008 015 084 U1 In this respect, an improved training or therapy device is known, which is versatile and allows in a simple manner to carry out counter-rotating or counter-directed movements (adduction / abduction) on the same device. By the movement of an actuating element, which can be moved by the user against a counterforce applied by the exerciser, a drive wheel is rotated about an axis fixedly arranged in the exerciser. The drive wheel can be brought into engagement with a coupling element, which can then be reciprocated against the counterforce in a reciprocating motion of the actuating element. According to a preferred embodiment, the drive wheel is associated with a pair of coupling elements in the form of racks, wherein the coupling elements can be selectively brought into engagement with radially opposite running surfaces of the drive wheel. The racks are arranged on a loaded with the counter-force slide, which can be moved by the movement of an actuating element of the training device. Although such a training device thus allows the execution of opposing or counter-directed exercises, the structure of the required mechanics is complex and thus prone to failure.

The object of the invention is therefore to provide an alternative training or therapy device with which the above-mentioned disadvantages of a complex mechanism are overcome.

The object is achieved by the provision of a training or therapy device according to claim 1. Further advantageous embodiments are given in the dependent claims, the description and the figures.

The training or therapy device according to the invention serves to carry out athletic or therapeutic exercises and comprises at least one of the exercising person with their extremities (legs, arms and parts of the same) engageable actuating element, which is opposed by the exercising person against a counterforce applied by the exerciser - and is movable. The training or therapy device is constructed such that, by means of the movement of the actuating element, an articulation element as a rotational body can be rotationally symmetrically rotated in both directions around a rotation or rotation axis fixedly arranged in the training device. This means that the at least one actuating element, starting from a neutral, initial or zero position, can be moved back and forth counter to the opposing force. The mounted on the rotary or rotational axis of the articulation element is designed as a rotational body substantially rotationally symmetric and therefore comprises with respect to the rotational axis or two symmetry halves, each with a running or contact surface, which by a symmetry axis, which in the case of the starting position of the actuating element perpendicular runs, are separated. The articulation element is connected or functionally coupled via a tension element to the counterforce, wherein the tension element can be brought into engagement with the running or contact surfaces of both symmetry halves of the articulation element in such a way that the articulation element counteracts the reciprocation of the at least one actuation element Drag is reciprocable.

According to a preferred embodiment, the tension element, which is further preferably selected from the group consisting of a belt, a rope, a chain, or hybrid forms thereof, at least one of the opposing force facing away from the hinge element and facing portion of its elongated extent, the simultaneous ( opposite) contact with the two symmetry halves of the coupling element is provided, designed in two parts (Y-shaped), so that the two parts of the tension element can be brought into engagement with the running or contact surfaces of the two symmetry halves of the coupling element simultaneously and in opposite directions. The two the Anlenkelement facing ends of such a two-piece designed tension element can be fixed in opposite directions at the different running or contact surfaces of the two Symmetriehälften of the coupling element, preferably spaced from each other. Alternatively, the two ends of the tension member may contact each other at the axis of symmetry, or even overlap beyond the axis of symmetry if desired.

According to an alternative embodiment, the tension member is provided over its entire length only in one piece, such as in the form of a rope, both ends are directly or indirectly connected to the counterforce, and wherein the tension member thus forms a loop in the central region of its elongated extent, the same time is brought into frictional engagement with the running or contact surfaces of both symmetry halves of the coupling element.

The devices according to the invention are thus distinguished by the fact that the actuating element or the actuating elements can be moved back and forth in two opposite directions, starting from a zero, neutral or initial position, wherein a counterforce is provided to both directions of movement. Therefore, these devices include a mechanism with which the force introduced by the training person on the actuator or the actuators in the system power is transmitted to the opposing force provided by the device, which is carried out according to the invention via a hinge element for articulating the training weights as a counterforce. The coupling element can be designed as a disk, roller, roller or cylinder, wherein the embodiment in the form of a coupling plate is preferred.

In the initial, neutral or zero position of the system (actuating element, actuating elements, articulation element), it is preferred that the rotational or rotational axis of the articulation element, such as the articulation plate and at least a first, the counter-force facing portion of the tension element along a straight line such as in particular a vertical are arranged, which can also be referred to in the present case as the axis of symmetry against the background of the above embodiments.

The counterforce is preferably provided in the form of multiple training weights, most of which are provided stacked on two guide rods within a weight tower. It is further preferred that the coupling of the coupling element takes place with the counterforce on the tension element and a support rod for the training weights, wherein the elongate extent of the retaining rod is preferably also on the above symmetry axis.

According to a preferred embodiment, the at least one actuating element can be released with respect to its application of the counterforce by means of a switching handle, so that the actuating element or the synchronized actuators in a simple manner without coupled counterforce in a desired position such as in an initial, neutral or neutral position can be brought and adjusted, and the positioning of the control handle should be easily accessible to the user, such. B. in a middle position of the weight tower, in which the counterforce in the form of several training weights and the hinge element and the tension element are provided. In this way, the exerciser can thus move the actuator or the actuators without effort to enter or leave the training device and to choose the starting position for the elements. It is preferred that the switching handle is coupled to a detent pin, which optionally engages in one of a plurality of detent holes, which are preferably provided by a perforated disc, which is fixedly connected to the coupling element. The switching handle thus serves the release or decoupling of the actuating element of the opposing force and is preferably carried out in the region of the coupling element, as will be explained in more detail below.

In a device according to the invention with only one actuating element, the transfer of force introduced by moving the actuating element into or out of the system by the exerciser via the coupling element preferably takes place directly and directly, d. H. without any intermediate mechanism, since the actuator or its Tragarmverlängerung and the coupling element are mounted on the same axis.

In contrast, the devices according to the invention with two actuators in addition to both elements synchronizing conversion gear and a drive wheel such as a pinion, which serves to transmit power to the coupling element and is also mounted on the same axis of rotation or rotation.

Hereinafter, embodiments of the invention will be explained with reference to the drawings.

The 1 shows a training or therapy device 1 with its functional components according to a first embodiment with two actuators 5 from different views, both in the starting position (A), as well as in a Turning to the right (B). Also shown is a handle 13 that with a locking bolt 29 interacts and an exemption of the actuators 5 from the drag 6 allows (C).

The 2 shows a training or therapy device 1 according to a second embodiment with only one actuating element 5 on the example of a lateral trainer from different views both in the initial position (A), as well as a rotational movement to the left (B) and to the right (C). Also shown is a handle 13 that with a locking bolt 29 interacts and an exemption of the actuators 5 from the drag 6 allows (D).

The 3 and 4 each show the weight tower 2 as well as the exposed bottom plate 4 of the training or therapy device 1 according to 1 , While in 3 the starting position for an adduction exercise is shown, shows the 4 the starting position for an abduction exercise. A respective direction of movement is indicated by corresponding arrows.

The 5 shows a preferred embodiment of the exposed bottom plate 4 a training or therapy device 1 with two actuators according to 1 , which are not shown for reasons of clarity.

In the 1 and 2 is in each case a training or therapy device 1 represented with its essential components from different views. The respective training or therapy device 1 has a weight tower 2 and a floor frame 3 in the 3 . 4 and 5 with removed bottom plate 4 is illustrated. In the floor frame 3 of the training or therapy device 1 according to 2 with only one actuator 5 is no conversion mechanism arranged as a rotation of the actuator 5 directly in the direction of the drag 6 is implemented. On the floor frame 3 is a pillar 7 fixed on which a seat 8th is arranged. The seat 8th serves as a training person for sitting. While the right side of the training person according to 1 to the weight tower 2 points, the person sits according to 2 head-on in front of the weight tower 2 ,

In 1 one recognizes further the design of the two actuators 5 as leg supports 9 , The training person can both the seat 8th in its height as well as its inclination as well as the distance between the leg rests 9 and the seat 8th with suitable adjusting devices 10 . 11 set individually. The actuators 5 are each about a support arm 12 in the ground frame 3 rotatably mounted in opposite directions and mechanically synchronized with respect to their rotational movement, so that they can be moved toward each other by the user or away from each other (according to the implementation of an adduction or Abduktionsübung).

In 2 is the embodiment of a lateral trainer 1 with only one actuator 5 illustrated, wherein on this actuating element 5 two arm levers 14 are attached. The seat 8th are two leg pads 9 assigned, whose height with an adjustment 10 can be adjusted.

In the 1 and 2 is also the operation of the handle 13 shown. The articulation element 23 or the baffle 23 is designed such that it has a perforated disc 34 can absorb. In the cover there is a hole through which a locking bolt 29 inserted and into a hole of the perforated disc 34 can be locked. The perforated disc 34 is with the articulation plate 23 firmly connected, such as bolted. The actuator 5 can with pulled locking pin 29 without coupled drag 6 set free and then in this position by pressing the locking pin 29 and snapping into the perforated disc 34 be fixed. As soon as the locking pin 29 again in the direction of the articulation element 23 been pressed and in a hole of the perforated disk 34 is engaged, the actuator is 5 or become the actuators 5 with the drag 6 applied. For better usability of this locking bolt 29 at the device as shown in 2 over a Bowden cable 35 and one on the actuator 5 positioned handle 13 operable.

In the 3 and 4 is based on a top view on the floor frame 3 and a rear view of the weight tower 2 Fig. 2 illustrates how the trainee makes a simultaneous, reverse rotation of the actuators 5 force applied to the system in the weight tower 2 provided drag 6 is transmitted. The two support arms 12 are each non-rotatable with a sprocket pair 15 connected, the storage of a support arm 12 and its associated sprocket 15 on the same axis 16 he follows. The synchronization of the counter-rotating movement of the actuators 5 or its support arms 12 via a cable arrangement 17 , which are in the range of the sprocket pair 15 is preferably designed as a chain or toothed belt to the transmission of high tensile forces on the cable arrangement 17 on the training weights 18 to allow.

As seen in the figures, the cable arrangement 17 over two pulleys 19 90 degrees in the longitudinal direction of the weight tower 2 diverted. Further shown are in the floor frame 3 arranged deflection sprockets 20 and a chain tensioner 21 , as well as in the weight tower 2 positioned further deflection sprockets 20 indicating the course of the cable arrangement 17 and favorably influence its slip-free operation. The cable arrangement 17 is designed such that movements of the sprocket pair 15 on another sprocket 22 in the weight tower 2 be transmitted. Because the movements of the actuators 5 over the synchronized sprockets 15 and the cable arrangement 17 as well as the sprocket 22 on the with the drag 6 coupled coupling element 23 is transmitted, takes place when pressing together or apart of the actuators 5 raising or lowering the training weights 18 ,

That in the weight tower 2 above the training weights 18 arranged sprocket 22 is with a vertically mounted coupling element 23 in the form of a coupling disc 23 coupled, the sprocket 22 and the steering disc 23 one in the weight tower 2 attached, substantially horizontally extending rotation or rotation axis 24 are rotatable and the rotation depending on the direction of movement of the cable arrangement 17 clockwise (s. 3 ) or counterclockwise (s. 4 ) runs. The cable arrangement 17 is along the area that is with the sprocket 22 cooperates, preferably formed as a chain.

The cable arrangement 17 may also consist entirely or partially of a toothed belt or have a continuous rope when the sprockets 15 are suitably replaced by rollers to which the cable arrangement 17 is wrapped several times to produce a good frictional engagement.

The articulation element 23 is as a disc, V-belt pulley or cylinder such. B. configured as a roller or roller and has a substantially round or rotationally symmetrical shape. In the embodiment of a coupling disc 23 has the hinge element 23 a front and a rear disc surface 25 as well as a circumferential edge 26 and can be rotated from a neutral or middle position as a starting position (symmetry axis perpendicular) to the right or left. The pivoting disc 23 is about a tensile element tensile 27 with a holding bar 28 coupled, through a series of training weights 18 extends. Depending on which, through which the side holes of the training weights 18 a mounting pin (not shown) is inserted, are the training weights located above the mounting pin 18 according to the movement of the holding rod 28 moved up and down. This movement of training weights 18 takes place under the leadership of two guide rods 30 ,

The tension element 27 stands with the articulation plate 23 engages and is at least in the region of the elongated extent of its intended contact or its intended guide with or through the coupling disc 23 two-piece (with two ends 27a . 27b ) designed. For this, the two stand the holding bar 28 opposite ends 27a and 27b of the tension element 27 so radially opposite to the circumferential arc or circular line of a disc or with the circumferential surface of a roller or roller in engagement that one end 27a . 27b upon rotation of the articulation disc 23 experiences a train while the other end 27b . 27a is relieved. The rotation of the coupling disc 23 clockwise or counterclockwise, therefore, leads to a raising or lowering of the support rod 28 with the training weights 18 , Because the tension element 27 thus against the opposing force 6 is always under tension or is tense, may be a delay in the transfer of the training person introduced into the system power on the training weights 18 be excluded.

Of course, the tension element 27 over its entire length, ie to the connection with the support rod 28 , be designed in two parts. Important for the functionality of the illustrated embodiment is only that of the training weights 18 or the stick 28 remote end portion of the tension element 27 over at least a length resulting from the desired guide length of the tension element 27 along the circular, arc or surface line of the coupling element 23 as a disc or as a roller or roller plus that for a complete raising or lowering of the support rod 28 or the training weights 18 by rotation of the articulation element 23 provided route, two-part (with two ends 27a . 27b ) is configured, so that the coupling element 23 or the baffle 23 , Whose or its axis of symmetry in the illustrated initial or neutral position perpendicular by the rotation or rotation axis 24 runs, with the vertical course of the tension element 27 and the holding bar 28 is on a straight line, and the total area (front, disc surface) of the coupling element 23 divided into two symmetry halves (left / right of the symmetry axis), capable of both ends 27a and 27b of the tension element 27 Both simultaneously and separately from each other and in opposite directions along the circular, arc or surface line of its two symmetry halves or along a parallel running path with a smaller radius (see below) to be able to. Towards the training weights 18 can the tension element 27 beyond this required minimum length be designed in one piece.

Although it is preferable that the two parts 27a . 27b of the tension element 27 along the Circumference, such as along the circular, arc or surface line of the coupling element 23 can be performed as a disc or as a roller or roller, the guide can also be provided by elements that on the hinge element 23 attached as a disc, roller or roller with a smaller radius. The functionality of the device according to the invention would be unchanged, since the two-part tension element 27 also according to this embodiment along a circular path on the coupling element 23 is performed as a disc, roller or roller, even if this circular path has a smaller radius compared to that of the embodiment set out above.

According to an alternative, not shown, embodiment, the tension element can also be configured completely in one piece, provided that the above-mentioned criteria of simultaneous and non-positive guidance along the circular, arc or surface line of both Symmetriehälften the hinge element 23 Fulfills. The two-part version of the tension element 27 is thus not essential to the present invention, although it is presently preferred.

To the optionally two-piece tension element 27 in a meaningful way over the entire duration of a training movement on both sides along the peripheral edge 26 of the articulation element 23 or the articulation plate 23 to be able to lead, are the hinge element 23 , preferably immediately adjacent, two at the weight tower 2 fixed guide aids 31 assigned, in the present case as roles 31 with mutually facing grooves for guiding the two-part section of the tension element 27 are designed. An imaginary connecting line of the axes of the two rollers 31 stands perpendicular to the axis of symmetry of the articulation element 23 (see above) and to the section of the tension element 27 who was the holding staff 28 or the training weights 18 facing horizontally in relation to the areal extent of the floor frame 3 , The guide aids 31 are configured such that the two initially mutually parallel ends 27a . 27b of the tension element 27 between them and then in opposite directions along the peripheral edge 26 of the articulation element 23 or the articulation plate 23 are feasible.

According to an embodiment, not shown, the guide aids 31 also further from the articulation element 23 be spaced apart.

At the in 2 illustrated embodiment, the transfer of the training person on the actuating element takes place 5 introduced power output directly, ie without intermediate gear or the like, on the coupling element 23 or the baffle 23 because both the actuator 5 as well as the articulation element 23 rotatable on one of the weight tower 2 fixed rotation or rotation axis 24 are stored. As another alternative to the in 1 illustrated embodiment, the training weights 18 in the weight tower 2 above the articulation element 23 or the articulation plate 23 arranged, which is why the tension element 27 as a transmitter in a rotation of the coupling element 23 converted power output of the training person on the counterforce 6 in the form of the training weights 18 with the help of suitable pulleys 19 a total of four times by 90 degrees is deflected. With regard to the functional interaction of the here at least partially two-piece trained tension element 27 with the hinge element 23 or the articulation plate 23 involving the management assistance 31 However, there are no differences to the in 1 illustrated embodiment, so that reference can be made in this regard to the above statements.

In 5 is an alternative embodiment of the in the floor frame 3 of the training or therapy device 1 shown with two actuators (not shown) arranged conversion gear. In addition to those related to 3 and 4 explained components is the sprocket pair 15 with a cable 32 connected in the form of a chain or a belt for the purpose of synchronization while on the axle 16 of the left sprocket 15 a coupled with it another sprocket 33 is mounted with a larger diameter, over which the cable arrangement 17 as described above to weight tower 2 is guided.
