Description

Summary of the invention

[0001] The invention relates to a gait training assembly comprising a treadmill frame and an endless belt running on rollers in the treadmill frame, or a slat running on a guide from the treadmill frame, the surface of the endless belt or the slat being used as a walking surface or running surface, the treadmill frame being mounted in a base frame or placed on the floor. The invention also relates to an alternative gait training assembly formed by a walking board or a training board.

[0002] The purpose of this application is to make gait training and running training, as well as balance and coordination training on a treadmill, walking board or training board more varied and interesting, but also to enable effective training to treat various diseases. It is particularly suitable for diseases such as stroke and Parkinson's, where it is very important to restore postural control and balance in order to be able to stand and walk with a minimum risk of falling. For the elderly, the special purpose is to maintain the elderly's walking ability and slow down muscle decline.

[0003] It is therefore an object of the present invention to provide a gait training assembly of the above-mentioned type which is improved with respect to therapeutic applications.

[0004] The object of the invention is achieved by a gait training assembly having the features of claim 1 or claim 2. Advantageous further developments of the inventive concept are subject matter of the dependent claims.

[0005] The gait training assembly according to the invention provides users, especially elderly users, with a new quality of pressure on the musculoskeletal system without the risk of accidents. Even when walking slowly, the activation rate of the stabilizing muscles, especially those in the pelvic area, trunk and joints, is significantly increased. Using the proposed assembly, cardiovascular and sensorimotor abilities can be significantly improved in a very short time.

[0006] Furthermore, the gait training assembly according to the invention is very advantageous for gait and posture analysis.

[0007] Furthermore, the gait training assembly according to the present invention can be used for gait and posture analysis, as well as for gait training of dogs and other mammals.

[0008] The present invention includes the use of elements to install a treadmill frame, or a substructure of a walking board or a training board, which provide a simple and cost-effective possibility of selectively adjusting the height (and for example the target inclination) of the treadmill frame or substructure at a specific point. Therefore, the achievable front-back tilt and / or lateral tilt of the running surface can achieve a special training effect in the above-mentioned situation. In addition, the above-mentioned elements also provide the possibility of installing a treadmill frame or substructure with adjustable elasticity. This in turn makes it possible to convert the reaction force applied to the endless belt or the walking board by the impact foot during walking or running into the swing of the endless belt or the walking board in a predetermined manner. The amplitude of these swings depends on the way the user's foot touches the ground and the force therefore controlled by the user, and on the other hand is also affected by the elastic adjustment of the above-mentioned elements.

[0009] Furthermore, the invention includes the lifting cushion alone to realize the combined functions of the above-mentioned elements. The lifting cushion is connected on the one hand to the base frame and on the other hand to a substructure of the treadmill frame or the walking board. In principle, the lifting cushion can also be arranged directly on the floor instead of on the base frame and can be fixed to the floor if necessary.

[0010] According to the invention, a lifting air cushion is provided at or near or on the side of each corner point in the direction of travel of the treadmill frame or walking board. This allows the front edge, the rear edge and / or one of the side edges of the treadmill frame or substructure to be raised in a flexible manner and also in a predetermined time sequence, so that the inclination or decline of the running surface can be adjusted as required. Although the formation of the inclination by filling (more) with lifting air cushions at the front edge is necessary for sports training. However, the formation of the slope by filling (more) with rear lifting air cushions is particularly useful for therapeutic or elderly applications.

[0011] The height and springiness of lifting air mattresses can be controlled by the amount of air they contain and / or the internal pressure, and have for this purpose air inlets / outlets through which air can be supplied or removed.

[0012] According to the invention, these air inlets are provided with electrically controlled valves and these valves are connected to an electric compressor and / or a compressed air tank. Typically, a manual air pump can also be used to fill the lifting air cushion in a controlled manner, but this is secondary in the actual implementation of the invention.

[0013] In order to control the filling of the lifting air cushion to reach the desired height and thus achieve a certain degree of elasticity, an electronic air cushion filling control unit is provided, which is designed to activate the compressor and the valve to set a defined filling level and thus set a defined height and elasticity of the lifting air cushion. In principle, the above-mentioned manual pump can also be equipped with a pressure gauge (manometer) in order to control the filling of the lifting air cushion. However, this is a low-cost solution and has little practical significance.

[0014] In both designs, the adjustability of the elasticity of the lifting air cushion can specifically influence or almost eliminate the swing response of the treadmill or walking board to the user's foot contact. In this way, the above training effect can be set and optimized in precise coordination with the user's physical condition and movement pattern. This also applies in particular to the combination of a targeted lift of the treadmill belt or walking board at one of its edges and a predetermined swing response generated only by the filling level of the lifting air cushion.

[0015] The design possibilities can be further developed by choosing a rather stiff or flexible treadmill or a rather stiff or soft walking board, if necessary by providing statically or dynamically generated unevenness on the treadmill or walking board, as explained by the applicant in an earlier patent application. The aforementioned design of the invention can also be combined with the generation of a coordinated visual presentation of a virtual running environment and / or the output of corresponding auditory and / or optical training instructions, which is also known.

[0016] In another structural embodiment, the treadmill frame or substructure or walking board or training board has a lateral cantilever connected to the upper side of the lifting air cushion, each cantilever being located at a corresponding position in the subframe. These cantilevers are connected next to the running surface opposite to the lower edge of the treadmill frame or base frame, or to the running surface opposite to the lower side of the walking board. In this way, to a certain extent, "building space" is created for the lifting air cushion placed below, and the running surface is not correspondingly higher. Thus, the possibility of realizing a low running surface and a low entrance thereon is of great value again, especially for the treatment and rehabilitation applications of elderly patients.

[0017] In another construction embodiment, at least a portion of the lifting air cushions is formed in several parts, each part comprising at least one partial air cushion having an air inlet with an electrically controlled valve. This allows a large range of height adjustment and optional elasticity adjustment to be achieved with stacked commercially available air cushions, such as are provided for assembly work in the trade sector or at home. Furthermore, conversion or repair of the gait training assembly can be carried out in a particularly flexible and cost-effective manner.

[0018] In a further embodiment, at least some of the lifting air cushions are provided with a stop and / or locking device for fixing the maximum height of the respective lifting air cushion. By means of these additional devices, a swinging (which is essentially desired) of the treadmill belt or the walking board can be suppressed. This is particularly advantageous for adjusting only the inclination of the running surface or the walking surface. In a particularly advantageous manner, the stop or locking device is arranged to be adjustable, in particular adjustable by an electric device.

[0019] In an advantageous embodiment, the arresting and / or locking device is provided with an additional damping device and is preferably arranged to be adjustable, in particular by electric means.

[0020] By means of such a damping device, continuous mechanical impacts of the locking device can be prevented and oscillations of the running or walking surface can be additionally damped, so that an optimum training effect can be achieved under almost all conditions and risks for the user can be minimized.

[0021] In a special structural embodiment, the base frame or walking deck or training deck of the treadmill comprises two independent cross-beam modules, each cross-beam module being designed as an elongated beam with a lifting air cushion fixed at each end. These cross-beam modules are connected to the treadmill frame, substructure or walking deck in the use position of the gait training component, either parallel to the front edge and the rear edge or at a certain distance parallel to the front edge and the rear edge.

[0022] In particular, the above structure can be used to retrofit existing treadmills or walking boards with lifting air cushions having the functions of the present invention and achieve the advantages achieved by the present invention. In particular, by arranging the lifting air cushions outside the walking, training or running surface, the step height can be kept low, which significantly increases the operability and safety of the training assembly.

[0023] In a further embodiment of the invention, height measuring means are provided for determining the height of a predetermined point of the treadmill frame or the walking or training board, which height measuring means are connected to a height sensor input of the air cushion filling control unit. Furthermore, pressure sensors associated with the lifting air cushions can be provided to determine the internal pressure of the respective lifting air cushions, which pressure sensors are connected to a pressure sensor input of the air cushion filling control unit.

[0024] The above-mentioned sensors are used to display basic operating parameters of the gait training assembly, and in particular also provide basic information that can be used to further adjust the gait training assembly. The basic information can be provided to the corresponding display unit via the corresponding sensor input of the air cushion filling control unit, and then the operator of the gait training assembly can control the internal pressure in the desired way, thereby controlling the height of the lifting air cushion.

[0025] However, in a preferred embodiment, the air cushion filling control unit has a program control device for program-controlled filling and thus adjustment of the height and elasticity of at least a portion of the lifting air cushion. This can be achieved in particular by processing signals from an electrical height measuring device and / or a pressure sensor to determine the internal pressure of the lifting air cushion. In an advantageous further development, the program control device is designed to store and implement a predetermined time course of the height and elasticity of at least a portion of the lifting air cushion as part of a predetermined running training program.

[0026] In a specific embodiment, a force sensor and / or a strain gauge or a plurality of pressure sensors arranged in a matrix are provided on the lower or upper side of the walking surface or the running surface or the walking board or the training board of the treadmill, and the measurement results thereof can be used for gait analysis and also for controlling the electronic air cushion filling control unit.

[0036] Fig. 9 An exemplary regulating device or control device of a gait training assembly according to the present invention is schematically shown in the form of a block diagram. DETAILED DESCRIPTION

[0037] Figure 1a and Figure 1b A gait training assembly 1 is shown in a sketch-like manner, wherein two rollers 3 are mounted in a treadmill frame 2, on which a treadmill belt 4 runs and is driven. Each roller 3 has a drive shaft or axis of rotation 3a, which can rotate with little friction in a bearing of the treadmill frame 2. The treadmill frame 2 is mounted on a base frame 6 via a plurality of lifting air cushions 5, so that it is height-adjustable on the one hand and can vibrate on the other hand. The function and structure of the lifting air cushions will be explained below by way of example.

[0038] Figure 2a to Figure 2c The adjustment and use possibilities of the gait training component 1' are schematically shown when a user N is training thereon. As a structural element of the gait training component 1', only a walking board 7 is schematically shown here, each corner point of which is fixed to a lifting air cushion 5, which is simply placed on the floor here.

[0039] Figure 2a An arrangement with a filled air cushion on the front edge and two empty air cushions on the rear edge is shown so that the upward inclination of the walking board in the walking or running direction of the user N is set to a predetermined inclination angle, which is determined by the filling degree of the air cushions. Figure 2b In a corresponding manner, the arrangement of the assembly is shown, in which the slope is set by filling the rear air cushion and emptying the two front air cushions.

[0040] Figure 2c An incomplete filling of all the air cushions at the longitudinal edges of the assembly is shown. The double-headed arrow shown is intended to indicate the fact that in this way an oscillation of the walking or running surface is produced both in the vertical and in the horizontal direction.

[0041] Figure 3a and Figure 3b A detailed view of the installation of the treadmill frame 2 is shown, with Figure 1a and Figure 1bCompared to the version shown, the treadmill frame 2 has been structurally modified and has a lateral cantilever 2a near each of its corners via a lifting air cushion 5 on a base plate 8. The lifting air cushion 5 has an air inlet 5a to which an electrically controlled valve (not shown) is assigned and through which the lifting air cushion 5 can be charged with a predetermined amount of compressed air L. Figure 3a A state is shown in which the lifting air cushion 5 is empty or only minimally inflated with air so that it has a minimum height, and the treadmill frame 2' is located on the floor. It should be noted that due to the design of the air cushion, in the completely unfilled state, the air cushion also has a certain minimum height. However, in accordance with Figure 1a and Figure 1b The design with lateral cantilever and the placement of lifting air cushions laterally outside the walking surface allows the step height to be significantly reduced compared to the version.

[0042] Figure 3b The (partially) filled state of the lifting air cushion 5 is shown, wherein its height has increased significantly compared to the initial state. Thus, the treadmill frame 2' is lifted off the ground and is elastically mounted on the lifting air cushion located below the corresponding cantilever 2a. Depending on the degree of inflation and the degree of elasticity of the lifting air cushion, this mounting is more or less elastic and can therefore be swung to an adjustable degree in the horizontal and vertical directions.

[0043] Figure 4a Shows relative to the Figure 3a and Figure 3b A modified version of the design of , in which an additional stop or locking device 9 is provided to limit the height of the lifting air cushion 5 and lock the treadmill frame 2 '.

[0044] The stop or locking device 9 comprises, for example, a stud or an externally threaded cylinder 9a, whose foot 9b is seated in a correspondingly designed hole 8a in the base plate 8. A height-adjustable stop and centering element 9c runs on the thread of the stud or cylinder 9a and engages with the hole 2b in the cantilever 2a. When the stop and centering element 9c is partially engaged in the hole 2b, the conical design of the stop and centering element 9c enables the treadmill frame 2' to be accurately guided laterally and prevents the component from swinging due to the contact force of the user when the lifting air cushion is filled. However, if the lifting air cushion is partially deflated, the treadmill frame can move freely in the vertical and horizontal directions.

[0045] Figure 4bThe additional damping of the locking device 9 is shown as an embodiment. The stop and centering element 9c can move freely upwards on the cylinder 9a until it encounters the adjustable limiting element 9f and is pressed against the hole 2b in the cantilever 2a by means of the spring 9e and the adjusting element 9d. The adjusting element 9d can be height-adjusted by means of a threaded element, thereby changing the spring force and the damping characteristics. This also prevents the centering element 9c from undesired and continuous impacts on the cantilever 2a during walking. As an alternative to the spring 9e, an elastomer can also be used and / or combined with the centering element 9c and completely or partially composed of an elastomer.

[0046] Figure 5 Schematically shows the Figure 2a to Figure 2c How can the gait training component 1' be implemented in a structurally simple and at the same time flexible manner. The support plate (substructure) 10 of the walking board or treadmill frame 7 has a recessed receiving area 10a formed by corresponding folding, and the walking board or treadmill frame can be removably inserted into the receiving area and fixed on all sides by folding. Therefore, the component can be easily transported and is very simple to be equipped with various walking devices, which differ, for example, in the hardness of the walking surface, or there are obvious unevenness, or also include sensors and / or actuators, with which additional functions can be realized, such as foot force detection or active generation of time-variable unevenness. It should be understood that the transverse cantilever can be incorporated in a transverse frame surrounding the walking device, or in a fully or partially enclosed shell, or can be designed as a part of such a shell.

[0047] Similar to Figure 1a and Figure 1b Components, mounted on a base frame or base plate 6. However, if the lifting air cushion 5 is firmly attached to the underside of the support plate 10, the support plate with the air cushion can also be simply placed on the floor.

[0048] Figure 6 Shows Figure 5 Detailed view of a further improved assembly 1 ″ later. Here, a base frame 6 ′ has raised side edges or lateral cantilevers 6 a ′ and a two-part lifting air cushion 5 ′ is placed thereon. This comprises a lower closed air cushion 5 . 1 with a fixed air volume and therefore a constant height and an upper air cushion 5 . 2 which can be filled with a desired amount of air via an air inlet and an outlet 5 a and can therefore be adjusted in height. In the region of the two-part air cushion 5 ′, the space between the side edges 6 a ′ of the base frame 6 ′ and the side edges of the support plate 10 is exemplarily closed by a flexible protective wall 11 in the shape of an accordion.

[0049] With the two-part design of the lifting cushion 5', on the one hand, a higher height can generally be achieved than with a one-part cushion, and on the other hand, the combination of a closed cushion with a fixed predetermined elasticity and a variable filling cushion with adjustable elasticity makes it possible to adjust the swinging behavior of a substructure or treadmill frame placed on the lifting cushion in a particularly flexible manner.

[0050] Figure 7 An improved design compared to the above-described version is shown, which has no continuous substructure and a continuous base frame. Instead, separate crossbeam modules are provided here, which are connected transversely to the front and rear edges of the walking board.

[0051] These cross-beam modules each comprise an elongated base frame module 6' and a matching formed substructure module 10', of which the end region is shown in each case. The cross-beam modules therefore have the reference numerals 6' / 10'.

[0052] As can be seen in the figure, the respective ends of the base module 6' and the substructure module 10' are slightly raised relative to the middle part and surround the two-part lifting air cushion 5', with a lower air cushion 5.1 and an upper air cushion 5.2 (such as Figure 6 Centering elements 12a and 12b are arranged on the one hand on the base frame module 6' and on the other hand on the underside of the substructure module 10' of the walking board (not shown here) in order to center the substructure when it is moved up and down during use by a user. In addition, the upper end of the centering rod or bolt 13 can be seen, which protrudes from the upper side of the module 6' / 10'. In principle, a stop and centering device of the type shown in FIG. 4 and described above can be provided here.

[0053] Figure 8 A top view of a gait training assembly is shown, wherein a conventional treadmill assembly (not specifically designated) having a treadmill frame 6 is placed on Figure 7 The crossbeam modules 6' / 10' of the type shown and described above are shown. It can be seen that the crossbeam modules 6' / 10' are located at the front edge and the rear edge of the treadmill frame, respectively. The treadmill frame is connected to the corresponding crossbeam modules by suitable (not shown) threaded connections or the like. As shown by the arrows, the crossbeam modules can also be very advantageously positioned at a certain distance parallel to the front edge and the rear edge. On the one hand, this can increase the possible adjustment angles for the upward and downward inclination, in particular the mechanical stability, so that bending of the walking surface in long walking devices can be prevented.

[0054] Such an assembly makes it possible to "retrofit" an existing conventional treadmill or walking deck with the elements of the assembly according to the invention described above, thereby implementing the invention in a particularly cost-effective manner.

[0055] Fig. 9The components of a gait training assembly of the type described above are shown by way of example, for filling the air cushion 5 in a controlled manner through the air inlet 5a. The components shown in dashed lines can be used as an alternative or in combination with the components shown in solid lines. The filling of the lifting air cushion 5 is carried out by a compressor 14 and / or from a compressed air tank 15 via a solenoid valve 16.

[0056] The air cushion filling control unit 17 determines the control signals for the compressor 14 and / or the solenoid valve 16 by processing the input signals supplied to the corresponding control signal inputs 17a, 17b of the control unit 17 by the internal pressure sensor 18 in the lifting air cushion 5 and / or the height sensor 19 on or in the air cushion 5. The input signal evaluation unit 17c evaluates the measurement signals in a suitable manner and supplies them to the comparator unit 17d. The device receives a set point signal from a program control device 17e, in which program data for filling the lifting air cushion (e.g. set point value or set point pressure or set point height time curve) are stored. The storage content in the program control device 17e can be changed by the operating unit 17f of the cushion control unit 17, and the compressor 14 and the optional solenoid valve 16 can be directly controlled by the operator.

[0057] With regard to the above exemplary explanation of the basic aspects of the present invention, it is expressly noted that gait training assemblies have been familiar to those skilled in the art for a long time and have been described in numerous patents and technical publications, including those of the applicant.

[0058] This also applies to special features, such as providing a treadmill frame with elastic suspension, an actuator for adjusting the inclination of the treadmill or user-independent movement of the treadmill frame. Providing means for controlling the speed of the treadmill (including according to the user's movement behavior or training program), or providing display means for presenting a virtual running environment and / or training instructions, is also known per se to the person skilled in the art. This also applies to pressure sensing sensor systems for detecting the contact and optionally the contact point and contact force on the walking surface or running surface, as well as other useful features for special purposes of the gait training component.

[0059] The above-described examples and aspects of the assembly according to the invention offer particular advantages with regard to the design of a simple structure of the gait training assembly and many possibilities for designing the movement of the treadmill frame and thus the movement of the walking surface in various horizontal directions in a very individual manner.
