Description

TECHNICAL AREA

The present invention relates to a treadmill ergometer for therapeutic applications and / or an intensive running training, with several force extraction units, which are connectable in their free end to limbs and / or the body of a training person, such that upon movement of the limbs and / or the body a force is exerted on the limb (s) or the body.

STATE OF THE ART

Training concepts are known in which treadmill training expander trains or elastic bands are used, which are held by the therapist, so that the trainee is opposed to resistance, or a relief of the lower extremities is given, and patented train units, namely the EP 1 221331 used on fitness equipment, profiled bars for use on fitness equipment DE 597 08 289 or walls are attached and elastics with train scales and slip clamps integrated on the towing hook for displaying and adjusting the training strength as they were presented at the FIBO fitness fair in Essen end of April 2000 for the first time on the body-spider fitness device to the public.

There are further training concepts known in which the treadmill training one from the EP 1 137 378 known device and a method for the automation of treadmill therapy is used.

In the US 2004/0043873 A1 is a treadmill ergometer of the type described above shown. On the treadmill ergometer cable pull units are present, which are introduced from behind to the training person and the training person grasps with his hands. This serves the purpose of making the training on the treadmill even more strenuous by the use of the arms and the corresponding upper-body musculature on actuation of the cable-pull units and to use even more energy. This is a pure Zugwiderstandsgerät given. Train support is not possible with this device. It is not possible to use this device in the therapy of patients with limited mobility.

In the US 2006/281606 A1 a treadmill ergometer is described in which forces are measured by means of an elastically connected lap belt / hip belt when the athlete accelerates or brakes. For movement support of neurological patients, such a device is not useful.

The US 2004/0087418 A1 discloses a treadmill with draw resistance units in different directions of action. The legs of the training person are connected to pull ropes from the front and from behind. This device is designed to strengthen the strengthening of the leg muscles during training by resisting forces. Lateral tractive forces or tensile supports - as in the case of therapy in neurological patients unavoidable - can not be exercised with this device.

In the EP 1 772 134 A1 A method of controlling the speed of a person walking on a treadmill is disclosed. It is about the speed control of the treadmill.

The WO 2004/050191 discloses a treadmill in which resistance ropes are connected from behind to the legs of the exerciser to achieve increased strengthening of the leg muscles. Such a treadmill is for treadmill therapy neurological patients are not suitable because the legs of the patient can not be moved forward under the supportive effect of elastic elements and also no lateral forces can be exercised.

The US 2007/0287601 A1 discloses a treadmill on which cable tracks are deployed that are alternately pulled by the exerciser during training alternately from the left and right hand against a resistance to additionally load the muscles of the arms and upper body. A train support of legs of neurologically damaged patients is not possible with such a device. Incidentally, such cable extraction units that simulate resistance have been known in other commercial products for decades, such as ski simulators.

WAYS FOR CARRYING OUT THE INVENTION

According to the Figures 5 . 6 . 9 . 10 For example, a treadmill ergometer 300 has a front training unit 400, which by means of an adapter unit 450 on the right front side of the treadmill and an adapter unit 460 on the left front side of the treadmill ergometer, which are fixed in the respective frame profiles 304, a rear training unit 500 by means of an adapter unit 510 is attached to a weight-relieving and securing system 301, or by means of a treadmill handrail adapter unit 520, such that there is the possibility of realizing this without additional attachment of bores or fasteners welded to the treadmill ergometer 300.

According to the FIGS. 7 and 8f For example, the adapter units 450 and 460 are mounted in the frame profiles 304 such that the treadmill base with fastening nut 458 is removed first, the adapter units 450 and 460 attached to the frame profile 304, and the treadmill foot with fastening nut 458 replaced by the mounting hole 453 of the flange plate 452 below screwed, and screwed as additional fastening thread screws 457, screwed into the threads 455 of the flange 454, frontally screw into the corners of the frame profile 304, with the stop 456 serves as an additional fixing aid in the attachment.

According to the Figures 5 . 6 and 8a and b For example, the rear training unit 500 is attached to a weight relief system 301 by means of an adapter unit 510 consisting of a pipe clamp part 1511 and a pipe clamp part 2 512, such that the connection screws 513 are connected through the horizontal detent tube of the rear training unit 504 and passed through the pipe clamp Part 2 512, and then the connection screws 513 in the pipe clamp part 1511 and be tightened.

For attachment of the rear training unit 500, directly on the front sides of the handrails of the treadmill ergometer 302 is according to the FIGS. 8c, d and e a plug-in adapter 521, which is respectively flanged on the left and right to the horizontal locking tube of the rear training unit 504, and in each of which by means of a fastening screw 523 a sliding part 522 is loosely screwed, introduced into the end faces of the handrails of the treadmill ergometer 302. A frictional connection of the adapter units for treadmill handrails 520 with the handrails of the treadmill ergometer 302 results from the subsequent tightening and tightening of the fastening screw 523 in the sliding part 522, as shown by the respective oblique design of the plug adapter 521 and the sliding part 522 both parts with the insides clamp the handrails of the treadmill ergometer 302.

The FIGS. 6 . 7a and 7b show the structure of the front left 401 and right training unit 402 whose pintle 420, to which a thrust washer 407 is welded, inserted into the receiving studs 451 of the adapter units 450 and 460, and screwed by means of screwing the pivot pin 421 frictionally after the left 401 and right training unit 402 were previously symmetrically aligned with each other.

Above the thrust washer 407 is a sliding washer 410, which is connected to the sliding bush adapter 419 and thus allows the rotation of the training units 401 and 402 about the axis of rotation of the pivot pin 420 approximately frictionless. The slide bushing adapter 419 into which the sliding bush 418 is inserted is welded to the rotary tube 412. This rotary tube 412 has at the top a welded flange 417 for the adaptation of the locking element socket 415, which screwed with the screws 416 with the flange 417, and in which also a sliding bushing 418 is used. The adjustment of the angular position of the training units 401 and 402 realize the detent elements 404 and 405, each having a scaling rotated with respect to each other, so that the left 401 and right training unit 402 can be set in position symmetry with respect to each other. The fixation of the position of the training units 401 and 402 is ensured by the fact that the locking element base has a rigid and a rotatable ring gear, positively secured by means of feather key on the pivot pin 420. For adjusting the angle, the locking head 413 is raised against the pressure force of the locking spring 414 so that the training units 401 and 402 can be rotated. After the desired angular position has been taken, the locking head 413 is released again. The locking spring 414 pushes the locking head 413 back over the rigid and the rotatable ring gear of the locking element socket 415 and thus fixes the entire unit form fit.

To the rotary tube 412 of the front left training unit 401 and the right front training unit 402 respectively cross tubes 409 and at the end of fixing bolts 408 for fixing the pivot bolt with screw 411, welded. This pintle 411, to which a thrust washer 407 is welded, is inserted into the fixing bolts 408 of the front left training unit 401 and the right front training unit 402 and frictionally bolted by means of screwing the pivot pin 411 after the pulling units 200 mounted over the pawls 403 , which at the top in each case have a flange 406 for fastening the latching elements 404 and 405, have previously been aligned symmetrically relative to one another. The fixation of the position of the locking tubes 403 is ensured by the fact that the locking element base 415, fixed to the flange 406 a rigid and a rotatable sprocket, positively secured by means of key on the pivot pin 411 has. For adjusting the angle of the locking head 413 is raised against the pressure force of the tumbler spring 414 so that the locking tubes 403 can be rotated. After the desired angular position has been taken, the locking head 413 let go again. The locking spring 414 presses the locking head 413 back over the rigid and the rotatable ring gear of the locking element socket 415 and thus fixes the position of the locking tubes 403 form fit. The welded to the locking tubes 403 flanges 406, and the lower end of the locking tubes 403 each have pressed sliding bushes 418, which ensure a frictionless rotation of the traction units 200. In addition, a sliding disk 410 is used for a frictionless rotation between the pressure plate 407 and the locking tubes 403.

As Fig. 6 The rear left training unit 501 and the right rear training unit 502 are shown by means of horizontal sliding tubes 507, in which square sliding bushes 202 are inserted on both sides and each having a locking pin 508, moved and fixed on the horizontal locking tube 504 for positional adjustment. On the horizontal sliding tubes 507 vertical sliding tubes 505 are welded in the two-sided square sliding bushings 202 are introduced and each having a locking pin 506 so that the vertical locking tubes 503 can be moved in height and fixed.

The train units 200 (shown in the front training unit 400 and in the rear training unit 500 (FIG. Fig. 2 ) are a modification of the train units 100 (FIG. Fig. 1 ), as these are not sufficient in terms of their adjustment for use with treadmill gauges 300. The traction unit 100 has been modified such that the traction unit 200 now has a deflection roller unit 102, which is fastened on a sliding tube 203 into which square sliding bushes 202 are pressed in on both sides. The sliding tube is provided with a locking pin 204, which allows the Umlenkrolleneinheiten 102 can be moved to the respective locking tubes 403 and 503 and thus the force extraction can be variably adjusted, or the possibility exists, by mutual displacement of the Umlenkrolleneinheiten 102, the training force to reduce. By moving the deflection roller units 102, the slip clamps 104 had to be moved into this Unit are integrated, carried out such that in the Umlenkrolleneinheiten 102 a slip clamp holder 201 is introduced, to both sides of the slip clamps 104 are screwed. The function of the Umlenkrollenmechanik remains the same in this new embodiment, carried out such that an elastic Zugseil 103 inserted between the guide rollers 115 of Umlenkrolleneinheit 102, laid from the outside via a guide roller 110 of the opposite Umlenkrolleneinheit 102, then from the inside over the guide roller 110 of the opposite guide pulley unit 102 laid back and returned to the opposite pulley unit 102 such that the elastic traction cable 103 is led out again between the pulleys 115. Both ends are then fitted with the Kraftzugeinheit 101, carried out such that successively the rubber buffer 109, the clamping screw 108, the stop sleeve 107 and the clamping sleeve with scale 106 placed over the elastic traction cable 103, the end of the elastic traction cable 103 then in the tow hook 105th inserted and the clamping sleeve with scale 106 for fixing the elastic tension cable 103 in the towing hook 105 is pressed over the tow hook 105. After the traction unit 101 has been attached on both sides, it is adjusted such that the stop sleeve 107 is pulled out of the deflecting roller unit 102 by a certain fixed amount and the stop sleeve 107 is screwed to the prestressed elastic traction cable 103 with the clamping screw 108. When pulling the tractor unit 101 from the Umlenkrolleneinheit 102 which is trapped within the traction unit 101 elastic traction cable 103 is stretched so that the clamping sleeve with scale 106 so far protrudes from the stop sleeve 107 that the indicated tensile force of the actual approximately corresponds. If this is not the case, the unit must be readjusted and the specified amount when removing the elastic traction cable 103, during the adjustment, to be redefined. This measure must be set again for each different elastic tension cables 103.

As in Fig. 6 shown, has proved to be mandatory for the creation of a training concept that the respective force extraction units 101 numbered on the Umlenkrolleneinheiten 102 and in the train units 200 different strength elastic tension cables 103 are mounted. This claim has been implemented such that the train units 200 mounted in the rear training unit 500 are numbered 1-8 and the train units 200 of the front training unit 400 have been numbered 9-16 and the force extensions 1-2, 7-8, 9-10, 15-16 weak and the force extensions 3-4, 5-6, 11-12, 13-14 have strong elastic pull cords 103 to cater to any exerciser or any form of training.

FIG. 3 shows, step by step, in various illustrations, the mode of operation of the force extension increase on the modified tractor unit 200 such that in a first step (FIG. Fig. 3a ) The example extract for increasing the tensile force 111 to the desired Zugkrafterhöhung, in an enlargement Fig. 3b shows, pulled out and the elastic Zugseil 103, as Fig. 3c shows, then inserted into the document clamp 104. When training on the sample extract 112 is in 3d figure and in an enlargement ( Fig. 3e ) it can be seen that when moving out immediately with the set increased traction is trained and at the same final position as when training without Zugkrafterhöhung how Fig. 3f and in an enlargement Fig. 3g shows, this tensile force is higher by the amount of Kraftauszugsvergrößerung.

Fig. 4 shows step-by-step, in various representations, the mode of operation of the power take-off reduction on the modified tractor unit 200 such that in a first step (FIG. Fig. 4c ) the Umlenkrolleneinheit 102 is moved to the opposite Umlenkrolleneinheit 102 and engaged. Fig. 4d shows in an enlargement of the tensile force at a certain final position, the same exit position, as Fig. 4a and in an enlargement Fig. 4b shows, which is lower by the displacement of the Umlenkrolleneinheit 102.

Since in many cases, especially in medical applications or the determination of training data in competitive sports, the display and the adjustment and readjustment of only approximately accurate tensile forces and tensile directions on the power take-off units 101 is not sufficient, in a further embodiment of the invention, the use of transducers for tensile force determination in the train units ( Fig. 11a ) and in an enlargement ( Fig. 11b ) the electromotive positioning of the deflection roller units ( Fig. 12 ), as well as the combination of both further developments on the basis of a block diagram ( Fig. 13 ).

As in Fig. 11a and in an enlargement Fig. 11b in a traction unit with integrated transducers 600, the modified deflecting roller units 602 are modified such that the deflecting rollers 110 are separated from the original deflecting roller unit 102 and displaced into a transducer unit 601, such that the deflecting rollers 110 are adapted in a deflecting roller holder 605, this pulley holder 605 is fixed to a guide shaft 610, the guide shaft 610 is guided by a shaft guide 607 and the other end of the guide shaft 610 is fixed to a clevis 608 in which one side of the transmitter 609 is adapted and between the pulley holders 605 and the shaft guide 607 a compression spring 606 is inserted over the guide shaft 610.

As in Fig. 11a and in an enlargement Fig. 11b the assembly of the elastic traction cable 103 is designed such that it is introduced between the guide rollers 115 of the Umlenkrolleneinheit 602, placed from the outside over the guide roller 110a, then placed from the inside over the guide roller 110b and returned to the opposite pulley unit 602 such that the elastic tension cable 103 is led out again between the pulleys 115. Both ends are then fitted with the Kraftzugeinheit 101, carried out such that successively the rubber buffer 109, the clamping screw 108, the stop sleeve 107 and the clamping sleeve with scale 106 placed over the elastic pull cable 103, the end of the elastic Traction cable 103 is then inserted into the tow hook 105 and the clamping sleeve with scale 106 for fixing the elastic traction cable 103 in the tow hook 105 is pressed over the tow hook 105, wherein the use of the traction units 600 and the installation of the clamping screw 108 and the stop sleeve 107 can be omitted because the transmitter unit 601 substantially improves the exact display of the tensile forces, in contrast to the conventional power take-off units 101 anyway.

As in Fig. 11a and in an enlargement Fig. 11b illustrated by an example is caused by increasing the tensile force with the example extract 604 and / or training with the example extract 603 a force F2 and / or F1, each compressing the compression springs used 606 and a reduction S2 plus S1 of the push rod 611 of the transmitter 609 and thus its ohmic resistance change entails. This change in length is proportional to the forces of the example extracts 603 and 604 and only dependent on the strength of the built-in compression springs 606 in the transmitter unit 601. Which force corresponds to which change in length is determined, for example, with a commercial calibrated electronic measuring scale by using the teach-in method Transducers 609 are adjusted. This method is shown in the further description of the invention.

As in Fig. 12 are shown in an exclusive training 700 pulley units with an integrated spindle nut 704 by means of actuators 701 and 710 by turning the upper threaded spindles 703 via vertically arranged spindle guides 706, wherein the respective position of the Umlenkrolleneinheiten 704 integrated by the in the servomotors 701 and 710 Incremental encoders 702 and 711 is monitored and guide roller units 704 by means of actuators 708 and 712 by turning the lower screws 705 via vertically arranged spindle guides 706 out, wherein the respective position of the Umlenkrolleneinheiten 704 by the in the servomotors 708 and 712 integrated incremental encoders 709 and 713 is monitored. The left and right side of the training unit 700 is guided by means of actuators 714 and 716 by rotating the horizontal mounted left threaded spindle 721 and the horizontally mounted right threaded spindle 719 via a horizontally arranged spindle guides 720, wherein the respective position of the left and right side of motorized traction unit 700 is monitored by the integrated in the servomotors 714 and 716 incremental encoders 715 and 717. The entrainment of the left side by a left-hand driver with integrated spindle nut 722 takes place on the right side with a right-hand driver with integrated spindle nut 718.

The function of the motorized front traction unit 750 will be described with reference to a block diagram shown in FIG Fig. 13 , realized in such a way that on the left side the servomotors 723 and 725 with the respectively integrated incremental encoders 724 and 726 and on the right side the servomotors 727 and 729 with the respective integrated incremental encoders 728 and 730 adjust the deflection roller units with integrated spindle nut 704 in the vertical , or monitor their position. The angular position of the left and right sides of the tractor unit 750 is realized by means of the rotary motors 731 and 733 and the respective angular position is monitored by the incremental encoders 732 and 734 integrated in the rotary motors 731 and 733.

Fig. 13 shows a block diagram of the necessary in particular for medical applications or in the determination of training data in competitive sports exclusive complete equipment such that on the respective Meßwertgebereinheiten 601 the display displays 801 for the force extractors 1,2,3 and 4, 802 for the force extractors 5,6,7 and 8, 803 for the force extensions 9, 10, 11 and 12, 804 for the force extensions 13, 14, 15 and 16 are arranged. On the display 801, a transmitter 609 is connected, and the servo motors 701, 708 and 714 with the respective integrated incremental encoders 702, 709 and 715, on the display 802 a Measuring sensor 609, and the servomotors 710, 712 and 716 with the respective integrated incremental encoders 711, 713 and 717, the display 803, a transmitter 609, and the servomotors 723, 725 and the rotary motor 731 with the integrated incremental encoders 724, 726 and 732 and on the display 804, a transmitter 609, and the servo motors 727, 729 and the rotary motor 733 with the respective integrated incremental encoders 728, 730 and 734. The displays are connected with interface cables 805 with a central 807, which realizes the power supply of the displays and a Having interface converter, which ensures the secure bidirectional data transmission from the control center to the displays or vice versa. The data cable 806 implements bidirectional data traffic from the center 807 to a central computer unit 808 and vice versa. For synchronization, in particular the speed regulation of the treadmill, caused by the Meßwertgebereinheiten 601 2 interface cables 809 and 810 are present, which ensure the connection center 807 and / or the connection central computer unit 808 respectively with the control 811 of the treadmill.

As already mentioned and in Fig. 11 and Fig. 13 are shown in the Meßwertgebereinheiten 601 sensors 609 installed, which are ideally designed as a linear potentiometer due to economical production. A certain extension length of the push rods 611 of the transmitter 609 always corresponds to a certain ohmic value. Before the use of the transmitter 609 to determine all training-relevant data and to control a training process to treadmill synchronization, the sensors installed in the Meßwertgebereinheiten 601 must be adjusted so that in a setting menu of the central computer unit 808 to be adjusted transmitter 609 is determined and this Determination on the corresponding display 801, 802, 803 or 804 by displaying a specific Justiervorgabe, eg 1 Kp, is transmitted, then a digital load scale is inserted into the tow hook, the Kraftauszugeinheit 101 to the display of 1 Kp on the Force scale is withdrawn, and this setting is then confirmed by the central computer unit 808 from. In this case, the analog signal of the measuring transducer 609, in this case a specific ohmic value, is stored in an electrically programmable and changeable storage medium of the respective displays 801, 802, 803 or 804. This process is carried out several times over a certain range of forces, the transmitter 609 being adjusted more precisely the more measuring points have been adjusted over the possible force extraction range. This adjustment of a transmitter 609 can, for economic reasons, transmitted via the central computer unit 808 to all other displays, and then also checked. Finally, in the technical embodiment of the invention, only the constant structure of the sensor units 601 is relevant for whether this transmission of the training data can be realized or each individual sensor 609 has to be adjusted. A further possibility of the adjustment results from the fact that an adjusting device 812 is connected between the displays 801, 802, 803 or 804 and the control center 807 such that the corresponding interface cables 805 are subtracted from the corresponding display 801, 802, 803 or 804, and the adjusting device 812 can be interposed. The use of a Justiergerätes 812, or the adjustment option from the central computer unit 808, allows the cost-effective production of the displays, as can be dispensed with an integration of a keyboard in the displays, due to this external adjustment.

In an expanded variant of the invention, the transducers and electronic controls can already be integrated in the alternative traction devices (for example a commercially available servomotor with flanged cable drum, magnet lifting motor, pneumatic traction device, etc.) and connected and networked with the aforementioned displays and computer units as well as interfaces.
