Definitions
- the invention relates to an auxiliary drive for a training device, which comprises at least a first force measuring device, a control device and a drive unit, and a system which comprises the training device and the auxiliary drive for the training device.
- both an existing training device in particular a strength training device
- a new training device can be equipped accordingly during assembly.
- the auxiliary drive according to the invention can also be dismantled without being destroyed, so that it can subsequently be used in another training device, for example.
- the quasi-modular structure of a system comprising the auxiliary drive and the strength training device also offers a manufacturer increased flexibility in production.
- the auxiliary drive can, of course, be manufactured and offered completely separately.
- Strength training devices are described by way of example, in which the overall movable mass can essentially be formed from a plurality of mass plates which lie vertically one above the other. By way of example, these mass plates are connected via a take-away sword and a pin, which are then moved accordingly and which define the total movable mass accordingly.
- the maximum training resistance is defined by determining the total movable mass, for which purpose the pin is attached accordingly. As a rule When the exerciser applies a force, this acceleration of the total movable mass is directed against the acceleration of gravity.
- the object of the invention is therefore to provide an auxiliary drive for a training device and a system which comprises the training device and the auxiliary drive for the training device in order to enable a safe and optimized load.
- the maximum training resistance is well defined by determining the total movable mass. If the exerciser now intentionally applies a force, the resulting acceleration of the total movable mass is directed against the acceleration of gravity.
- a secure mechanical connection between the mass plates and the other movable mechanics of the training device can be established in a relatively simple manner.
- the total movable mass is well defined, namely essentially by the mass plates connected to each other by means of the pin.
- the maximum training resistance defined by defining the total movable mass - which requires a certain / known acceleration - cannot be exceeded unintentionally or unexpectedly, because on Due to the total moveable mass, even the exerciser must always exert a maximum force corresponding to the product of the total moveable mass and the desired acceleration against the acceleration due to gravity.
- the auxiliary drive according to the invention for the training device can therefore, from the point of view of and with effect for the trainee, only ever seemingly reduce the total movable mass and the resulting load, but never actually increase it.
- the auxiliary drive for training devices according to the invention maintains these two essential safety features, in particular the maximum possible (desired) training resistance, which is well defined by the overall movable mass.
- the design of the auxiliary drive for training devices according to the invention offers the particular advantage that the maximum possible training resistance, which is well defined by the overall movable mass, is achieved but can never be exceeded unintentionally.
- the auxiliary drive according to the invention always acts on the overall movable mass in such a way that at least one component of the resulting force caused by the action acts against gravitational acceleration, that is, against gravitational acceleration or gravitational acceleration.
- auxiliary drive Another very important advantage of the auxiliary drive according to the invention lies in being able to generate a so-called "eccentric overload".
- eccentric overload In a movement phase when the muscle is stretched (eccentric contraction) and experiences a higher load than it does in the the muscle-shortening concentric movement phase (active muscle shortening; concentric contraction) was previously exposed or when it was exposed to a length that is resistant to resistance (isometric contraction)
- the force in the concentric phase is always slightly higher than in the eccentric phase, but since the muscles could be stressed up to about 30% higher in the eccentric contraction, a corresponding training review is given here e Muscles are lost, which in turn triggers only reduced muscle growth.
- the fluid load control during a movement which is made possible by means of the auxiliary drive according to the invention, also allows the force profiles to be optimally matched to the lever ratios of an exercise and a trainee. It can also be seen when a trainee should adjust his load. As a result, automated training allowance adjustments are also possible.
- the auxiliary drive according to the invention as a retrofit kit can be designed such that only additional elements are mounted, but no mechanical changes need to be made to the existing mechanics or to a cover or to a force-transmitting part of the existing strength training device. There is also no need to dismantle traction cables and weight plates, and no specialist personnel trained in the use of electrics or electronics are required to put the device into operation and to monitor it during normal operation.
- the mechanics of the auxiliary drive according to the invention can be formed from a number of common machine elements, as a result of which the costs for procurement, operation, maintenance, maintenance and replacement can be reduced.
- a auxiliary drive for a training device which has the features mentioned in claim 1.
- Such a auxiliary drive for the training device can comprise at least a first force measuring device, at least one control device and at least one drive unit.
- the control device can determine a target force, Fs.m ax , which should correspond to the maximum load on the exerciser.
- This target force, Fs. Max can be changeable both in terms of time and with regard to additionally determined variables; such a change can be continuous, almost discrete and / or cyclical.
- the target force, Fs.ma can, for example, depending on a direction of movement, a speed of movement, one Change in the speed of movement, a value of the cardiovascular system of the exercising person or a combination formed therefrom; A large number of physiological values are conceivable that can be included in the calculation of the target force, Fs, max.
- the first force measuring device can determine an actual force, Fs, which can be applied to a main traction means of the training device, on which the trainee acts, and which can essentially be caused by an acceleration of a movable mass connected to the main traction means.
- a main train center! can be a rope or a belt, for example, a machine element that is suitable for transmitting a tensile force.
- This acceleration of the movable mass can be both the always acting gravitational acceleration or gravitational acceleration - that is, the essentially constant acceleration due to gravity - and an additional dynamic acceleration brought about by the exerciser.
- the actual force, Fs, determined on the main traction means can be transmitted from the first force measuring device to the control device.
- the control device can then compare the transmitted actual force, Fs, with the target force, Fs, max, and - if the actual force, Fs, exceeds the target force, Fs.ma - the control device can control the drive unit control in such a way that by connecting the drive unit to the movable mass, an auxiliary force, Fz, can act on the movable mass, which has a component that counteracts the acceleration due to gravity.
- the control device Since the control device only controls the drive unit when the actual force measured on the main traction device, Fs, exceeds the target force, Fs.max, the load for the trainee can never be greater than the load resulting from the movable mass and the total acceleration acting on them. If the exerciser does not apply any load that leads to an actual acceleration of the movable mass against the acceleration of gravity, the acceleration of the movable mass acts as the acceleration due to gravity. Therefore, if at least one component of the assistant, Fz, acts against the acceleration of gravity, it is guaranteed that the trainee can never unexpectedly experience a possibly dangerously high load. This protection can also be further increased by deliberately giving the assistant absolute or is restricted relative to the movable mass; for example to a maximum of 150N or 20% of the movable mass.
- auxiliary worker, Fz can be limited in the case of a fully functioning auxiliary drive for the training device, even if a complete system failure is assumed, the additional load cannot go beyond the lost limited auxiliary worker, Fz, and thus, for example, only amount to a maximum of 20% of the movable mass. In addition to increased security, increased power consumption can also be avoided.
- auxiliary drive for the training device can provide an emergency braking function of the drive unit.
- a safety emergency stop function implemented in hardware can be integrated, which can then short-circuit windings of an electric motor of the drive unit.
- the movable mass can be braked with a maximum torque of the electric motor in the event of an error or even in the case of disproportionately different measured values, which for example exceed a limit value.
- the controller can compare the transmitted actual force, Fs, with the target force, Fs.max, and, if the actual force, Fs, exceeds the target force, Fs.max, the controller can Activate the drive unit in such a way that the connection of the drive unit with the movable mass reduces the auxiliary force, Fz, the actual force, Fs, which is present and determined on the main traction means.
- the controller can Activate the drive unit in such a way that the connection of the drive unit with the movable mass reduces the auxiliary force, Fz, the actual force, Fs, which is present and determined on the main traction means.
- the control device can compare the transmitted actual force, Fs, with the desired force, Fs.max, and, if the actual force, Fs, exceeds the desired force, Fs.mex, the control device can control the drive unit in such a way that, by connecting the drive unit to the movable mass, the auxiliary force, Fz, the actual force, Fs, which is present and determined at the main traction means, is reduced essentially to the target force, Fs.max. In this way, it can be verifiably ensured that the force to be applied by the trainee now essentially corresponds to the target force, Fs.max, for example except for existing friction losses.
- the actual force, Fs also changes due to the control, since the auxiliary force, Fz, is permanently adjusted. While maintaining all of the positive safety features described above, an almost arbitrarily adaptable and opti izable load for the exerciser can be generated.
- the auxiliary drive can additionally comprise a movement sensor, which can be configured to determine a direction of movement of the movable mass and to transmit it to the control device, and the control device can also be configured to additionally determine the target force, Fs.max, depending on the direction of movement of the to determine movable mass.
- a movement sensor which can be configured to determine a direction of movement of the movable mass and to transmit it to the control device
- the control device can also be configured to additionally determine the target force, Fs.max, depending on the direction of movement of the to determine movable mass.
- the "eccentric overload" described above can thus be generated, as a result of which an improved muscle build-up can be achieved since the load to be exerted by the exerciser can be adapted in a positive manner to the current direction of movement.
- the motion sensor of the auxiliary drive can also be configured to determine an absolute or relative position of the movable mass and / or its first and / or second time derivative, or a correspondingly proportional quantity, and to transmit this to the control device, and the control device can the target force, Fs.max, can also be configured as a function of the position of the movable mass and / or its first and / or its second to determine the time derivative. This enables an even finer adjustment of the target force, Fs.max, to relevant parameters, so that the training effect can be increased due to the improved and, in particular, refined courses.
- the motion sensor can be integrated in the drive unit, whereby both a particularly space-saving design can be guaranteed and special protection against possible external damage. Furthermore, the integrity of the measurement can be increased if the motion sensor carries out the measurement directly in the drive unit, and consequently no further machine elements are involved which could falsify the measurement.
- the first force measuring device of the auxiliary drive can be configured to determine a tension of the main traction means in order to determine the actual force, Fs.
- the voltage is known, it is possible to infer very precisely the applied actual force, Fs, which also increases the precision of the control resulting from the comparison with the target force, Fs.max.
- the first force measuring device can advantageously be configured such that the tension of the main traction means is determined with the aid of a deflection. This represents a particularly reliable method of determining the voltage and consequently determining the applied actual force, Fs, which in turn increases the reliability of the control resulting from the comparison with the setpoint force, Fs.max.
- the first force measuring device can be configured to determine an elongation of the main traction means in order to determine the actual force, Fs. Even from a stretch, the actual force, Fs, can be traced very precisely.
- the first force measuring device can be a strain gauge and / or comprise a magnetostrictive sensor that works on the principle of magnetostriction.
- strain gauges and magnetostrictive sensors are available in a wide variety of designs from current suppliers and are therefore well adapted to the respective needs, which also allows costs to be reduced.
- strain gauges in particular are very space-saving and can also be easily accommodated in places that are difficult to access.
- the first force measuring device can be configured to determine the actual force, Fs, by comprising a weighing device that can be configured to determine the mass of the movable mass and by further comprising an acceleration sensor that can be configured to determine a second temporal change in a position of the movable mass.
- the actual force, Fs can be determined directly from Newton's second law by simple multiplication.
- the weighing device must, for example, measure a difference between a weight force at a point at which the moveable mass rests in the case that the moveable mass only rests under the influence of gravitational acceleration and in the event that the moveable mass does not rest .
- the acceleration sensor can be a motion sensor that can be configured to determine the absolute or relative position of the movable mass and its first and second time derivatives, or a variable that is correspondingly proportional to it. It is conceivable that the motion sensor described above is used in the configuration described here, as well as that an additional motion sensor is used, the data of which can then be used in addition to that of the existing motion sensor and from which further measured values, in particular after sensor data fusion has taken place.
- connection of the drive unit to the movable mass can also act at a first point of the main traction means, which is closer to the movable mass than a second point of the main traction means, at which the first force measuring device determines the actual force, Fs.

- the drive unit can comprise a generator, which, in particular in the case of eccentric movement, may not only consume no energy, but may even be able to recover energy, since the generator provides, for example, the braking torque required to achieve the appropriate assistant, Fz, to bring up. Since the energy consumption can be reduced in this way, possibly existing batteries / accumulators can fail smaller and cheaper.
- the auxiliary drive can additionally comprise a second force measuring device that is configured to determine the auxiliary force, Fz, which acts on the movable mass and / or to determine the work effectively performed by the drive unit.

- the operating unit can be configured to specify the target force, Fs.max, and in particular also its course or its change. For example, you can choose from a number of different training programs, from which the applicable target force, Fs.max, is then determined.
- a comparatively simple control device can also be used here, in addition to that of the Operating unit obtained courses of the target force, Fs.max, no or only to a small extent carries out further calculations to determine the target force, Fs.max.
- control device can also be configured to transmit data to the operating unit and / or to an IT infrastructure and to receive data from the IT infrastructure.
- the operating unit can also be configured to receive data from an external measuring unit and / or data from the IT infrastructure and / or to transmit them to the IT infrastructure. This makes it possible, for example, to show the trainee how best to follow target courses. Results can also be transmitted to the operating unit in order to ensure that a selected target is checked.
- the data can also be transferred to the IT infrastructure, such as a computer or a cloud, for analysis and evaluation. In particular, the temporal development of a trainee can be displayed and checked well, and useful adjustments can be made.
- statically or dynamically determined quantities of the trainee can also be carried out via the control unit, either by input or by forwarding data to the control device, or the corresponding calculations can be carried out in the control unit itself.
- cardiovascular values are also conceivable, which are suitable for determining a corresponding training plan.
- the specification for the ultimately generated target force curves, Fs. Max can also come from a (possibly second) IT infrastructure, such as a computer or a cloud. However, they can also be generated in the operating unit itself or in the control device.
- the adjustment of the target force, Fs.m a can also proceed continuously: for example, the IT infrastructure can receive the determined cardiovascular values from the control unit, together with the data that the control device transmits to the control unit. The IT infrastructure can then in turn make a corresponding adjustment of the target force, Fs.max, and transmit it to the control device via the operating unit. Restrictions to a single specific structure are therefore not necessary.
- the basic redundancy for determining the target force, Fs.max can be regarded as particularly advantageous since, depending on the (current) data availability and computing power, different units may be particularly suitable.
- the auxiliary drive can further comprise an auxiliary traction rope, which is indirectly or directly connected to both the drive unit and the movable mass and thus establishes the connection of the drive unit to the movable mass.
- the direct connection can be considered to be particularly less complex and therefore prone to failure.
- the auxiliary train may appear to be particularly suitable for establishing a space-saving and secure connection between the drive unit and the movable mass.
- a large number of ropes are designed and available for a wide variety of requirements, which means that costs are also kept within limits.
- a hydraulic connection would also be conceivable, further mechanical connections - for example by means of a gear.
- the drive unit can be designed as a rope drum, so that the auxiliary pull rope can be wound up in a particularly space-saving and safe manner. On the one hand, this protects against possible damage, on the other hand, unwanted contacts to other elements, such as the main traction device, can be avoided - especially if a relatively long area of the auxiliary traction cable has been wound up.
- the drive unit can also be configured to always provide sufficient torque to wind the auxiliary traction rope, which can further increase safety, since the voltage prevailing in the auxiliary traction rope can minimize the probability of contact with other elements and also the response behavior , especially due to the lack of play, can be further improved.
- the invention is also a system that can include a training device and a auxiliary drive for the training device with the features described above, wherein the movable mass can comprise one or more weight plates that can be connected by means of a carrying sword and a pin and in two essentially parallel Guide rods can be movable, wherein the connection of the movable mass to the main traction means can take place via the entraining sword.
- the overall movable mass can be defined in a particularly simple and reliable manner and its safe guidance can also be ensured.
- the auxiliary drive of the system can additionally comprise two outer deflection rollers and two rear deflection rollers, which can be connected to the movable mass by a first and a second connecting device, furthermore a first upper clamping device, which can be non-positively attached to one of the two parallel guide rods and a second upper clamping device which can be non-positively attached to the other of the two parallel guide rods, the first upper clamping device being able to receive a first end of the auxiliary pulling cable, the auxiliary pulling cable can be guided through the two outer deflecting rollers and through the two rear deflecting rollers, and the drive unit can receive a second end of the auxiliary cable.
- the drive unit can act on the movable mass in such a way that it can be guided parallel to the two parallel guide rods without a resulting and therefore braking torque being generated. This reduces the friction, thus the resistance and also the wear, and therefore enables an increased precision of the controlled loading of the exerciser.
- the drive unit then only has to apply half of the total auxiliary force, Fz, acting on the movable mass, which is why it can also be more compact.
- the auxiliary drive can also have a second drive unit (not shown) comprise, which can receive the first end of the auxiliary cable instead of the first upper clamping device. It may then be possible, for example due to the design, to control one of the two drive units very quickly by means of the control device 2 and to control the other very precisely, as a result of which both can advantageously be combined.
- the drive unit can be connected to the movable mass in such a way that the movable mass is directly or directly connected to a first end of the auxiliary traction cable and the drive unit receives a second end of the auxiliary traction cable.

- FIG. 5 a third view of the auxiliary drive
- FIG. 6 a second detailed view of the auxiliary drive
- FIG. 7 a fourth view of the auxiliary drive
- FIG. 8 a fifth view of the auxiliary drive
- Figure 9 a third detailed view of the auxiliary drive and
- FIG. 1 shows a first view of the auxiliary drive for the training device and a corresponding training device.
- the auxiliary drive for the training device comprises at least a first force measuring device 1, at least one control device 2 (not shown) and at least one drive unit 3.
- the control device 2 determines a target force, Fs.max, which should correspond to the maximum load on the exerciser.
- This target force, Fs.max can be changeable both in terms of time and with regard to additionally determined variables; such a change can be continuous, essentially discrete, and particularly cyclical.
- the target force, Fs.max can be determined, for example, as a function of a direction of movement, a speed of movement, a change in the speed of movement, a biometric value of the exerciser or a value of the cardiovascular system of the exerciser or a combination formed therefrom; There is a variety of physiological or biometric values conceivable that in the calculation of the target force, Fs. m a x, can be incorporated with.
- the first force measuring device 1 determines an actual force, Fs, which is applied to a main traction means 11 of the train ing device, on which the trainee acts, and which is essentially caused by an acceleration of a movable mass 5 connected to the main traction means. Such a main train center!
- This acceleration of the movable mass 5 includes both the always acting gravitational acceleration or gravitational acceleration - that is, the essentially constant acceleration due to gravity - and an additional dynamic acceleration brought about by the person exercising.
- the actual force, Fs, determined on the main traction means 11 is transmitted from the first force measuring device 1 to the control device 2.
- the control device 2 compares the transmitted actual force, Fs, with the target force, Fs.max, and, if the actual force, Fs, exceeds the target force, Fs.max, the control device 2 controls the drive unit 3 so that by connecting the drive unit 3 to the movable mass 5, an auxiliary force, Fz, acts on the movable mass 5, which has a component against the acceleration due to gravity.
- FIG. 2 a first detailed view of the auxiliary drive, the connection of the drive unit 3 to the movable mass 5 is shown as an example of a simple pulley, which is why the assistant, F, is divided into two halves of equal size.
- the control device 2 Since the control device 2 only drives the drive unit 3 when the actual force, Fs, measured on the main traction means 11, exceeds the target force, Fs.max, the load for the exerciser can never be greater than the load resulting from the movable mass 5 and the total acceleration acting on them. If the exerciser does not apply any load which leads to an actual acceleration of the movable mass 5 counter to the acceleration due to gravity, the acceleration of the movable mass 5 acts as the maximum acceleration. Therefore, if at least one component of the assistant, Fz, acts against the acceleration of gravity, this ensures that the exerciser can never unexpectedly experience a dangerously high load.
- This protection can also be increased further by deliberately limiting the auxiliary force absolutely or relative to the movable mass 5; for example to a maximum of 150N or 20% of the movable mass 5. Since the auxiliary worker, F z , can be limited in the case of a fully functioning auxiliary drive for the training device, even if a complete system failure is assumed, the additional load cannot be exceeded by the limited auxiliary worker, Fz, go out and thus for example amount to at most 20% of the movable mass 5. In addition to increased security, increased power consumption can also be avoided. Since the trainee can usually only apply a force, which has a component against the acceleration of gravity, to the movable mass 5 via the main traction means 11, the trainee can only be relieved by the assistant, Fz, but never additionally loaded. Only the unexpected absence of the assistant, Fz, would mean a correspondingly unexpected load, which, however, would then only be caused by the well-defined movable mass 5 under the influence of the acceleration due to gravity.
- the auxiliary drive according to the invention for training devices thus has as an essential security feature that in particular the maximum possible Training resistance is well defined by the total movable mass 5.
- the design of the auxiliary drive for training devices according to the invention offers the particular advantage that the maximum possible training resistance well defined by the total movable mass 5 is achieved, but can never be exceeded.
- the auxiliary drive according to the invention always acts on the overall movable mass 5 in such a way that the auxiliary force, Fz, which acts on the movable mass 5, has at least one component against gravitational acceleration, i.e. against gravitational acceleration or gravitational acceleration.
- auxiliary force, Fz compared to the force acting alone due to the gravitational acceleration due to the movable mass 5, can only reduce, but never increase, the force to be applied by the trainee.
- the assistant, Fz itself can be finely controlled, so no discrete differences in mass, for example between individual weight plates, have to be accepted by the trainee.
- Maintaining the maximum possible training resistance safely is also one of the main advantages of the present invention compared to active training devices (all-electric strength training devices) which can generate a dynamic resistance purely electrically. Such devices also require a very high level of security in order to avoid excessive loads or possibly even injuries in the event of a fault. Basically, the costs of both purchase and maintenance are very high for active training equipment (fully electric strength training equipment).
- the force actually to be applied, and thus the load on the trainee can be continuously adjusted during the exercise, while the set maximum training resistance is guaranteed to be maintained according to the total movable mass 5.
- an arbitrarily finely graded maximum load which can at most correspond to the mechanically predetermined maximum training resistance, can be set.
- Such a maximum load can also be during be adjusted to perform an exercise.
- a purely temporal adaptation or an adaptation with regard to a predetermined cycle is also conceivable here, which can also take into account cardiovascular values or biometric values of the exerciser.
- the auxiliary drive according to the invention can be designed as a retrofit kit so that only additional elements are installed on an existing strength training device, but no changes need to be made to the existing mechanics or a cover or force-transmitting parts of the existing strength training device. There is also no need to dismantle traction cables and weight plates, and no specialist personnel trained in the use of electrics or electronics are required to be able to put the device into operation and to monitor it during normal operation.
- auxiliary drive for the training device can advantageously provide an emergency braking function of the drive unit 3.
- a safety emergency stop function implemented in hardware can be integrated, which then short-circuits the windings of an electric motor of the drive unit 3.
- the movable mass 5 can be braked with a maximum torque of the electric motor in the event of a fault or even in the event of disproportionately different measured values which, for example, exceed a limit value.
- the control device 2 compares the actual force, Fs, transmitted to it with the target force, Fs.max, and determines that the actual force, Fs, exceeds the target force, Fs.max.
- the control device 2 advantageously controls the drive unit 3 such that, by connecting the drive unit 3 to the movable mass 5, the auxiliary force, Fz, the actual force, Fs, which is present and determined on the main traction means 11, is reduced. In this way it can be checked, namely by means of the first force measuring device 1, that the actual force, Fs, applied to the main traction means 11 has actually been reduced by the auxiliary force, Fz, so that safety can be increased.
- the auxiliary drive can therefore check whether the auxiliary force, Fz, the actual force, Fs, applied to the main traction means 11 actually reduces or whether the applied auxiliary force, Fz, the actual force, Fs, applied to the main traction means 11, recognizably reduces.
- the control device 2 compares the actual force, Fs, transmitted to it with the target force, Fs.max, and determines that the actual force, Fs, exceeds the target force, Fs.max.
- the control device 2 advantageously controls the drive unit 3 such that, by connecting the drive unit 3 to the movable mass 5, the auxiliary force, F z , the actual force, Fs, which is present and determined on the main traction means 11, essentially depends on the target force , Fs.max, reduced. In this way, it can be verifiably ensured that the force to be exerted by the exerciser essentially now corresponds to the target force, Fs.max, for example except for existing friction losses or measurement inaccuracies.
- the auxiliary drive can advantageously additionally comprise a movement sensor 8 (not shown), which is configured to determine a direction of movement of the movable mass 5 and to transmit it to the control device 2.
- the control device 2 may also be configured, the target force, in addition to determine Fs. M a function of the direction of movement of the movable ground 5.
- the "eccentric overload" can thus be generated, whereby an improved muscle build-up can be achieved, since the load to be exerted by the exerciser can be adapted in a positive way to the current direction of movement % are loaded more than in the concentric contraction, whereby the desired training stimulus on the muscles is triggered by means of a correspondingly adjusted target force, Fs.max, and a correspondingly modified auxiliary force, and a correspondingly increased muscle growth is triggered.
- the motion sensor 8 can be integrated directly into the drive unit, thereby ensuring both a particularly space-saving design and special protection against possible external damage. Furthermore, the integrity of the measurement can be increased if the motion sensor 8 carries out the measurement directly in the drive unit 3, and consequently no further machine elements are involved which could falsify the measurement because, for example, they can oscillate or have play.
- the first force measuring device 1 of the auxiliary drive can be configured to determine a tension of the main traction means 11 in order to determine the actual force, Fs.
- the control of the drive unit 3 by the control device 2 is basically based on the comparison of that of the first Transmitted force measuring device 1 actual force, Fs, with the target force Fs. Max. Consequently, the increased precision of the determination of the actual force, Fs, also gives rise to the possibility of controlling the drive unit 3 more precisely.
- the first force measuring device 1 can be configured such that the tension of the main tension means 11 is determined by means of a deflection; see also FIG. 1.
- the first force measuring device 1 can have a spring mechanism, the deflection of which is greater the greater the tension present in the main traction means 11. Consequently, the actual force, Fs, can be determined from the deflection of the spring mechanism.
- the first force measuring device 1 can also be configured to determine an elongation of the main traction means 11 in order to determine the actual force, Fs. Even from a stretch, the actual force, Fs, can be traced very precisely.
- the first force measuring device 1 can be a strain gauge, DIVIS, and / or comprise a magnetostrictive sensor that works on the principle of magnetostriction.
- strain gauges and magnetostrictive sensors are available in a wide variety of designs from current suppliers, which are therefore well adapted to the respective needs, which can also reduce costs.
- the quantities determined can be compared with one another directly or taking their respective changes into account.
- strain gauges in particular are very space-saving and can also be easily accommodated in places that are difficult to access.
- the first force measuring device 1 can be configured to determine the actual force, Fs, by comprising a weighing device (not shown), which can be configured to determine the mass of the movable mass 5, and by further comprising an acceleration sensor (not shown), which is configured to determine a second temporal change in a position of the movable mass 5.
- a weighing device not shown
- an acceleration sensor not shown
- the actual force, Fs can be determined directly from Newton's second law by simply multiplying the two values determined.
- the weighing device must measure a difference between a weight force at a point at which the movable mass 5 can be detected in the event that the movable mass only rests under the influence of gravitational acceleration and in the case that the movable mass does not rest . It is advantageous here that the weighing device only has to determine the difference described above, and it is therefore immaterial whether additional masses are weighed in each case. For example, it is also possible to mount the weighing device under a mass plate stack comprising a number of mass plates, of which only the uppermost ones, for example both massep! atten are lifted. As already described above, several types of determination of the actual force, Fs, can be carried out both as an alternative to one another and in parallel with one another.
- the present invention considers it to be extremely advantageous if - quite generally - determined quantities are determined in different ways and / or several times; sensor data fusion can also serve this purpose.
- the dynamics of the underlying movement in sensor data fusion can be important, as can the dynamics of the change in the determined values.
- the acceleration sensor can be a motion sensor that is configured to determine the absolute or relative position of the movable mass 5 and its first and second time derivatives, or a variable that is correspondingly proportional thereto. It is conceivable that the motion sensor 8 described above is used in the configuration described here, as well as that an additional motion sensor is used, the data of which can then be used in addition to that of the existing motion sensor 8 and from which further data can also be used Measured values, in particular after sensor data fusion has taken place, can be determined.
- the motion sensor 8 described above can determine the acceleration of the moving mass 5, it is therefore sufficient for the first force measuring device 1 to include the weighing device described above, in order to then use the determined values of the motion sensor 8 and the weighing device to determine the actual value applied to the main traction means 11 -Force, Fs.
- the acceleration determined by the additional motion sensor can again be compared with the acceleration determined by motion sensor 8, thus improving the integrity of the measurement, for example.
- the connection of the drive unit 3 to the movable mass 5 can also act at a first point of the main traction means 11, which is closer to the movable mass 5 than a second point of the main traction means 11, at which the first force measuring device 1 is the actual Force, Fs, determined.
- the drive unit 3 acts according to the invention at the first point of the main traction means 11, a particularly compact design of the auxiliary drive can also be achieved.
- the drive unit 3 can comprise a generator (not shown), which makes it possible, in particular in the case of the eccentric movement, that not only is no energy consumed, but even energy can be recovered, for example because the generator has the required braking torque to bring up the appropriate assistant, Fz. Since the energy consumption of the drive unit 3 is thus reduced and additional energy is generated by the generator, any batteries / accumulators that may be present can also be smaller and cheaper, or can be used correspondingly longer. If there are no batteries / accumulators, the generator will reduce the power consumption and thus the costs; environmental protection is also promoted.
- the auxiliary drive can additionally comprise a second force measuring device (not shown), which is configured to determine the auxiliary force, Fz, which acts on the movable mass 5, and / or to determine the work effectively performed by the drive unit 3.
- Fz auxiliary force
- the control of the drive unit 3 can be checked, the precision of the control can be increased and the error detection can be improved. In areas in which the control could unintentionally cause a vibration, this can be better avoided.
- the second one Kraftmessi direction be integrated in the drive unit 3, which enables a compact, protected design, increases the integrity of the measurement and also enables a comparatively simple force-displacement determination in order to determine the effectively performed work.
- the second force measuring device can also comprise a magnetostrictive sensor.
- the power actually actually produced by the drive unit 3 can also be determined. Basically, in addition or as an alternative, the corresponding variables can also be determined using a determined torque.
- the auxiliary drive can additionally comprise an operating unit 4 (not shown), which is configured to transmit data to the control device 2, from which the control device 2 can additionally determine the target force, Fs.max.
- the operating unit 4 can be configured to specify the target force, Fs.max, and in particular also its course or its change, as a rule, over time. For example, you can choose from a number of different training programs, from which the applicable target force, Fs.max, is then determined.
- a comparatively simple control device 2 can also be used here which, in addition to the curves of the target force, Fs.max obtained from the operating unit 4, does no or only to a small extent further calculations in order to determine the target force, Fs.max to determine. It is therefore also conceivable to have a fundamentally modular structure that can very explicitly also provide redundancies, that is to say different units can carry out the same or similar calculations. This further increases the flexibility and range of applications of the auxiliary drive.
- control device 2 can additionally be configured to transmit data to the operating unit 4 and / or to an IT infrastructure (not shown) and to receive data from the IT infrastructure.
- the control unit 4 can also be configured, data from an external measuring unit (not shown) and / or data received by the IT infrastructure and / or transmitted to the! T infrastructure! This makes it possible, for example, to show the trainee how he can best follow or have followed the desired course.
- results for example the number of cycles or the work performed by the trainee or current variables such as the current performance, can be transmitted to the operating unit 4, in order to provide information and to ensure that a selected target is checked.
- the data can also be transferred to the IT infrastructure, such as a computer or a cloud, for analysis and evaluation.
- statically or dynamically determined quantities of the trainee can also be carried out via the control unit, either by input or by data transfer, to the control device 2 or the corresponding calculations can be carried out in the control unit 4 itself.
- other biometric values or (current) cardiovascular values are also conceivable that are suitable for determining a corresponding training plan.
- the specification for the ultimately generated target force curves, Fs.max can also come from a (possibly second) IT infrastructure, such as a second computer or a second cloud. However, they can also be generated in the control unit 4 itself or also in the control device 2.
- the adjustment of the target force, Fs.max can also proceed continuously: for example, the IT infrastructure can determine the cardiovascular values determined by the control unit 4 and that together with the data that the control device 2 transmits to the control unit 4. The IT infrastructure can then in turn make a corresponding adjustment of the target force, F $, ma x, and transmit it to the control device 2 via the operating unit 4. Restrictions to a single specific structure are therefore not necessary.
- the basic redundancy for determining and presetting of the target force, Fs. M a x may be regarded as especially advantageous, since, depending on the (instantaneous) Data availability and computing power different units may be particularly suitable.
- the auxiliary drive can further comprise an auxiliary traction cable 12, which is connected to both the drive unit 3 and the movable mass 5 indirectly, as shown in FIG. 1, or directly, as shown in FIG. 10, and thus the connection of the drive unit 3 to the Movable mass 5 manufactures.
- the direct connection shown in FIG. 10 can be considered to be particularly less complex and therefore prone to failure.
- the auxiliary traction cable 12, in addition to a belt, may appear to be particularly suitable for establishing a space-saving and secure connection between the drive unit 3 and the movable mass 5.
- a large number of specifiable ropes are designed and available for a wide variety of requirements, which means that their costs are also kept within limits.
- a hydraulic connection of the drive unit 3 to the movable mass 5 would also be conceivable, as well as further mechanical connections - for example by means of a transmission, which can also include a slip clutch, for example.
- the drive unit 3 can be designed as a cable drum, see FIG. 1, as a result of which the auxiliary traction cable 12 can be wound up in a particularly space-saving and safe manner. On the one hand, this protects against possible damage, and on the other hand, undesired contacts to other elements, for example the main traction means 11, can be avoided - especially when a relatively long area of the auxiliary traction cable 12 has been wound up. This also minimizes the risk of injury to the exerciser or other people will.
- the cable drum can have a pinch protection (not shown).
- the drive unit 3 can also be configured to always provide sufficient torque to wind the auxiliary pull cable 12, which can further increase safety, since the probability of contact with other elements can be minimized due to the voltage prevailing in the auxiliary pull cable 12 furthermore, the response behavior, in particular due to the lack of play, can be further improved.
- the movable mass 5 comprises one or more weight plates, which are connected by means of a carrying sword 6a and a pin 6b, and essentially two parallel guide rods 7a and 7b are movable, the connection of the movable mass 5 to the main traction means 12 via the entrainment bar 6a.
- the overall movable mass 5 can be defined in a particularly simple and reliable manner and its safe guidance can also be ensured.
- the driving sword 6a Since the driving sword 6a generally rests on the uppermost mass plate with a wider area than a cross-section of the driving sword 6a in the mass plate, the driving sword 6a together with the pin 6b ensures that the movable mass 5, even if it has several Includes weight plates or mass plates is held together.
- Figure 3 shows a second view of the auxiliary drive.
- the auxiliary drive of the system can additionally comprise two outer deflection rollers 19a and 19b and two rear deflection rollers 20a and 20b, which are connected to the movable mass 5 by a first and a second connecting device 13a and 13b a first upper clamp 10a that is on one of the two parallel guide rods 7a is non-positively attached and a second upper clamping device 10b which is non-positively attached to the other of the two parallel guide rods 7b, the first upper clamping device 10a being able to receive a first end of the auxiliary pull cable 12, the auxiliary pull cable 12 by the two outer pulleys 19a and 19b and can be guided by the two rear pulleys 20a and 20b, and the drive unit 3 can accommodate a second end of the auxiliary cable 12.
- the system can be designed in such a way that the drive unit 3 acts on the movable mass 5 by means of the auxiliary force, Fz, in such a way that it is guided parallel to the two parallel guide rods 7a and 7b without generating a resulting and therefore braking moment would.
- 4 shows a first sectional view of the auxiliary drive along the line KK of FIG. 3. As shown in FIG. 4, in order to prevent the undesired moment, there are essentially vertical sections of the main traction means 11, the auxiliary traction cable 12 and both central axes of the two parallel guide rods 7a and 7b essentially in one plane.
- the drive unit 3 only has to apply half of the auxiliary force, Fz, acting on the movable mass 5, which is why it can also be more compact.
- Fz auxiliary force
- the auxiliary drive can further comprise a second drive unit (not shown) which receives the first end of the auxiliary pull cable 12 instead of the first upper clamping device 10a. It may then be possible, for example due to the design, to control one of the two drive units very quickly by means of the control device 2 and to control the other very precisely, as a result of which both can advantageously be combined.
- the second connecting device 13b can have a second sliding bush 14b, which in turn is fixed to the movable mass 5 connected as a second lower clamp; in the area of the first guide rod 7a, the auxiliary drive accordingly comprises a first connecting device 13a, which is connected to a first sliding bush 14a, which in turn is firmly connected to the movable mass 5, as a first lower clamping device.
- One or more screw connections can be provided in each case for fastening the two lower clamping devices and the two upper clamping devices 10a and 10b.
- the clamping devices can be made in one or more parts. A two-part embodiment, each with two screw connections, permits particularly simple assembly both on the sliding bushes 14a and 14b ⁇ see FIG.
- the two outer deflection rollers 19a and 19b and the two rear deflection rollers 20a and 20b each deflect the auxiliary traction cable 12 essentially by 90 °.
- first and the second connecting device 13a and 13b can also be connected to each other via a third connecting device 13c.
- the connection of all the mentioned connecting devices to the movable mass 5 is in turn carried out by means of a securing bolt 6c in each of the two third connecting devices 13c. Because the two lower clamping devices can be dispensed with here, no negative influence whatsoever can be exerted on the sliding bushes 14a and 14b, which could possibly result in increased friction between the sliding bushings 14a and 14b and the two parallel guide rods 7a and 7b.
- first and the second connecting devices 13a and 13b can also be connected directly to the uppermost mass plate and thus by means of a first and a second fastening belt 9a and 9b the movable mass 5 can be connected.
- a center line of the respective fastening belt 9a or 9b and the corresponding vertical section of the auxiliary traction cable 12 are each essentially in one plane. In this way it can be avoided that a torque acting on the first or the second connecting device 13a and 13b is generated via the two outer deflection rollers 19a and 19b.
- first and second fastening belts 9a and 9b can each be tensioned via a first and a second tensioning device 15a and 15b. This enables the tool-free assembly of the first and second connecting devices 13a and 13b with the uppermost mass plate.
- the drive unit 3 can also be connected to the movable mass 5 in such a way that the movable mass 5 is connected directly to a first end of the auxiliary traction cable 12 and the drive unit 3 receives a second end of the auxiliary traction cable 12.
- This particularly compact design minimizes susceptibility to errors and maintenance.
- the rope length of the auxiliary hoist egg 12 can be roughly halved if one assumes the same lifting height of the movable mass 5, since the simple pulley is eliminated. If a lower torque of the drive unit 3 is desired or required, a multiple pulley block (not shown) can of course also be used to establish the connection between the drive unit 3 and the movable mass 5.
