Abstract

Training equipment equipped with a progress indicator and a uniform base, the base being suitable for various types of equipment, such as a dynamometer, a spin bike, a recumbent bike, a home gym, a rowing machine, an elliptical machine, a cross-trainer or a treadmill. Each type of said fitness equipment is based on a uniform body structure based on a construction technique, the frame or the support having rollers arranged on the frame or the support in such a way that the frame is positioned against tipping over relative to the ground, while the frame or the frame together with the support can be displaced longitudinally relative to the ground by means of an actuator depending on the degree of completion of the training by the user.

Description

Technical Field

[0001] This invention relates to training equipment, also known as fitness equipment, such as force gauges, exercise bikes, recumbent bicycles or recumbent force gauges, home exercise bikes or force gauges without wattage, rowing machines, elliptical trainers, cross trainers, and even treadmills. Different types of this training or fitness equipment are particularly suitable for use at home as exercise bikes or in a gym. Background Technology

[0002] As people's interest in maintaining health through physical exercise grows and urbanization deepens, more and more people are using fitness equipment indoors, such as in gyms or at home. At the same time, the range and variety of gym and home training equipment are constantly increasing. This includes various types of equipment such as dynamometers, stationary bikes, recumbent bikes or recumbent dynamometers, home exercise bikes, rowing machines, elliptical trainers, cross-trainers, or treadmills. Despite the abundance of equipment, users may find exercising at home, or even in a basement or a more elaborate gym, quite monotonous after a while. People may try to alleviate boredom by installing entertainment devices such as television screens. However, this is not always successful, as it is essentially a distraction. Such actions can even be risky, reducing focus on the sport itself. Depending on the type of exercise, reduced focus can also pose safety risks (EP 3 327 597 A1). Another known method is to display virtual competitors on the screens of training equipment to provide users with a benchmark for comparison, thereby creating an artificial competitive atmosphere. In this case, virtual competitors can be computer-generated or can display the actual performance of other users, for example, they exercise in an indoor cycling group in the same room and thus compete against each other, or they exercise remotely in other places and connect via an internet data connection (US 8,409,057B2).

[0003] Another type of training equipment has a support bracket on the rear axle for supporting a standard bicycle. Such equipment is known to be mounted on a platform-like substructure (US10,434,394B2). The platform can be tilted or mounted longitudinally on the substructure via curved raceways. The curved shape of the raceways stabilizes the center position, allowing the platform to perform passive, oscillating longitudinal movements around this center; similarly, it can also tilt laterally during forward and backward movements. This creates a certain illusion of movement for the user and can improve their balance.

[0004] Overall, however, the problem remains that pure training on training equipment is relatively monotonous and provides users with almost no feedback on their training performance. Summary of the Invention

[0005] The purpose of this invention is to create an improved training or fitness equipment that can reduce the aforementioned disadvantages.

[0006] The key advantage of this invention is that it provides a structural technology solution that can easily realize various training or fitness equipment while being safer for users, such as reducing the risk of crush injuries and minimizing maintenance costs.

[0007] The technical solution of the present invention is characterized in the independent claim. Advantageous further developments are the subject of the dependent claims.

[0008] The training or fitness equipment of the present invention includes a drive device for receiving training performance provided by a user and a force transmission device for transmitting the user's performance during training to the drive device.

[0009] This invention relates to various types of fitness equipment, such as force gauges, exercise bikes, recumbent bicycles or recumbent force gauges, home exercise bikes, rowing machines, elliptical trainers, cross trainers, or treadmills; that is, fitness equipment designed as one of the aforementioned types of equipment. The structural technology of this invention is applicable to any of the aforementioned types of fitness equipment. In other words, the body structure or platform of all equipment types has a unified structural technology; that is, a structural base is created on which various types of equipment with different shapes can be mounted. The technical solution is, in turn, realized by the structural features of such body structure or base as described below.

[0010] The fitness equipment also includes a frame with a drive mechanism and a force transmission mechanism, the frame being designed to support the user of the fitness equipment during exercise, and a support bracket that supports the frame and provides ground support.

[0011] In addition, the fitness equipment is equipped with at least one sensor for detecting the user's training performance and a control device designed to receive data from the at least one sensor. This control device works in conjunction with a computing unit designed to determine a so-called completion rate based on the user's training performance. As explained in detail below, completion rate can be understood as a quantifiable metric that reflects the user's training performance.

[0012] The fitness equipment also includes a signal unit designed to generate a signal for a so-called progress indicator based on a determined level of completion. As explained in detail below, the progress indicator is a metric calculated based on optional reference data according to the aforementioned level of completion.

[0013] The aforementioned advantages, namely the ability to build various fitness equipment on a unified structural body or base applicable to a wide range of fitness equipment, stem from the unique nature of this structure. Furthermore, the fitness equipment's frame or support has rollers arranged to prevent tipping and to position the frame relative to the ground, while also allowing for longitudinal displacement of the frame or the frame together with the support relative to the ground.

[0014] In addition, the fitness equipment has at least one actuator designed to move the frame relative to the support in the longitudinal direction via rollers, or to move the frame together with the support relative to the ground in a motorized manner, based on a signal generated by a signal unit based on the degree of completion.

[0015] As described above, the fitness equipment of the present invention can be designed as a force gauge, exercise bike, recumbent bicycle, home exercise bike, rowing machine, elliptical trainer, cross trainer, or treadmill. These different types of fitness equipment typically have different dimensions. For example, a treadmill usually has a wider frame than a force gauge, exercise bike, or home exercise bike, while a rowing machine or recumbent bicycle (recumbent force gauge) usually has a longer frame than a force gauge, exercise bike, or treadmill. Therefore, the support dimensions of each type of fitness equipment need to be adjusted accordingly. The support frame for a rowing machine can be correspondingly longer, and the support frame for a treadmill can be correspondingly wider, but the construction technology, body structure, and construction method of all types of training equipment or fitness equipment remain the same. The dimensions of the corresponding equipment support can be compensated for by the telescopic structure of the support. For example, the rowing machine support can be easily extended, and the treadmill support can be easily widened.

[0016] In contrast, exercise equipment such as force gauges, stationary bikes, and home exercise bikes (i.e., force gauges without wattage) are roughly the same size. Therefore, the same frame can be used for these types of equipment. Because of the standardized body structure or base, users can easily replace equipment themselves; for example, a force gauge can be replaced with a stationary bike. It can also be replaced with an elliptical trainer and cross-trainer.

[0017] In a preferred embodiment, the fitness equipment has at least one roller driven by a servo motor of the actuator, causing the frame or the frame together with the support to undergo longitudinal displacement relative to the ground.

[0018] In another preferred embodiment, the fitness equipment has at least one sensor for detecting the user's training performance. This sensor may be mounted on the drive mechanism and / or force transmission mechanism.

[0019] In this case, one or more of the rollers described above may preferably be designed as friction rollers, ratchet rollers, toothed rollers, sliding rollers and / or running rollers.

[0020] Particularly preferred is that the fitness equipment according to the present invention is designed as a force gauge, a stationary bike, a recumbent bicycle, or a home exercise bike.

[0021] In this case, the frame of such fitness equipment, namely a force gauge, exercise bike, recumbent bicycle or home exercise bike, can consist of two crossbeams, each with a roller at one end, the rollers being placed on the ground, and at least two rollers being driven by a servo motor.

[0022] Optionally, the support can be composed of two crossbeams, with sliders and / or rollers arranged at the ends of each crossbeam. The sliders and / or rollers are placed on the ground, with at least one roller driven by a servo motor serving as a maneuverable central roller, or arranged as a set of drive rollers on a cantilever between the two crossbeams.

[0023] In another embodiment, the wheels of the fitness equipment, i.e., a force gauge, exercise bike, recumbent bicycle, or home exercise bike, may be arranged on a frame and run on or within a guide rail of the support. In this case, at least one drive roller is designed to move the frame relative to the fixed support and therefore also relative to the ground.

[0024] Preferably, the computing unit of the fitness equipment is designed to control the actuator in a reversible manner.

[0025] Furthermore, preferably, the signal unit of the fitness equipment works in conjunction with an amplifier module designed to allow the progress indicator to take into account the acceleration generated by training performance.

[0026] Another preferred embodiment is to design an end-effector detector on the actuator of the fitness equipment, which is designed to shut down and / or reverse the actuator when the end position is reached. The actuator can be designed in a form-fit manner.

[0027] In another preferred embodiment, the actuator of the fitness equipment is designed as a slow-motion actuator that drives at least one roller at a speed lower than walking speed and not exceeding 1 m / s.

[0028] Furthermore, preferably, the actuator of the fitness equipment may have a traction controller for at least one drive roller, which detects slippage of at least one drive roller and feeds it back to the computing unit.

[0029] In another preferred embodiment, the actuator of the fitness equipment has a position detection device designed to output a signal to the computing unit.

[0030] Preferably, the position detection device has a sensor designed to detect ground track markers. In this case, the ground track markers can be designed as track markers with distance markings.

[0031] In this case, the ground track markings can be designed as marking strips. These marking strips can be placed on the ground. Furthermore, the fitness equipment can have an alignment module designed to detect and display directional deviations based on the ground track markings.

[0032] In a preferred embodiment, the alignment module is designed to indicate the correction direction.

[0033] The preferred features of the training or fitness equipment according to the present invention help the user of the fitness equipment experience a stronger sense of training success, thereby promoting the user to improve training performance and thus enabling the user to obtain a better real fitness experience.

[0034] Furthermore, the rollers of the fitness equipment can be mounted on a frame or support, enabling the frame, or the frame together with the support, to perform actions such as longitudinal displacement relative to the ground with low risk of crush injuries. With the frame of the fitness equipment mounted on the support via the rollers, the user's limbs, such as their feet, are generally not (unlike devices known from published document KR20190029151 A) trapped or crushed within the frame and support. This safety consideration is particularly important when the user uses the fitness equipment unsupervised, such as in a hospital or clinic without the supervision of a medical professional, as is often the case in gyms or homes.

[0035] Other advantages of the fitness equipment of the present invention can be seen from the force gauge example described below.

[0036] A dynamometer, particularly a bicycle dynamometer, is equipped with an anti-tipping frame. On this frame are a user seat, a user-operated pedal unit, and a support bracket with ground-supporting feet. The pedal unit acts on a braking device, and a control device controls the braking device and is connected to at least one sensor that records the user's training performance. According to the invention, this control device works in conjunction with a computing unit designed to determine completion based on user-provided training performance according to training reference data, and with a signal unit that generates a signal to a progress indicator based on the completion level. An actuator motorically moves the frame with the seat and pedal unit longitudinally (thus changing its relative position to the ground), the actuator being automatically controlled by the computing unit based on the signal from the progress indicator.

[0037] The following will first explain some of the terms used:

[0038] A force gauge can generally be understood as a training device designed for indoor use (fitness studios, users' residential rooms). Of course, a force gauge can also be placed outdoors.

[0039] A pedal unit can be understood as a device that primarily utilizes the user's training abilities. This training is typically aimed at the lower limbs, such as the legs or feet, as seen on stationary bikes or cycling trainers, (especially flywheel-less) indoor bikes, treadmills, or cross-trainers. However, the term can also be understood more broadly and encompass upper limb training, as these are also used, particularly on rowing machines or similar equipment, to utilize training abilities.

[0040] A support frame can be understood as a structural component that supports a force gauge, allowing the force gauge to stand upright on a base surface, especially the floor of a room or gym.

[0041] Longitudinal refers to the direction that is primarily parallel to the bottom surface (horizontal), roughly along the longitudinal axis of the force gauge. Depending on the type of force gauge, the training effort applied by the user will form a specific training activity, and the quotient of this activity with time will yield training performance.

[0042] The training effort exerted by the user and the resulting training performance on an indoor dynamometer are not lost due to other factors. For example, unlike moving a bicycle outdoors in a natural environment, where the trainee needs to expend training performance to increase riding speed and overcome air resistance, the dynamometer does not have such natural resistance. Instead, it has a braking mechanism. It can be designed in various known ways, such as as a friction brake, a magnetic brake, a generator that produces electrical energy, or a fluid brake (e.g., a rotating element in a fan or water container).

[0043] Completion rate can be understood as a quantifiable metric that reflects the training performance provided by the user. For example, for a bicycle dynamometer, completion rate could be speed and / or distance traveled; for a treadmill, it could be speed and / or incline reached; for a rowing machine, it could be rowing distance traveled or speed achieved. It can be an absolute or relative metric relative to selectable and / or preset training reference data. Training reference data can be created manually, for example, calculated by the computer on the dynamometer. It can come from stored processes (e.g., previous training performance achieved by the user), and / or from the training performance of other users using the same equipment or another similar piece of equipment connected to the dynamometer via a (remote) data connection, especially the internet.

[0044] A progress indicator is a metric calculated based on optional reference data to indicate completion. For example, when using a bicycle dynamometer or treadmill, it can use the ratio of distance run to a preset target distance as reference data, such as how much of a 10,000-meter run has been completed, or how much of a 50km bike workout has been completed. However, it can also be a relative metric, such as progress relative to another training session, like one's previous training (running against oneself), or comparison with other users' performance on different training equipment.

[0045] The longitudinal movement of the frame with seat and pedal unit can be understood as the change in the relative position of the frame with seat and pedal unit relative to the ground on which the force gauge training equipment is arranged, viewed from the longitudinal direction of the training unit.

[0046] The actuator can be understood as a servo drive with a control unit that changes the position of the dynamometer training equipment assembly (or possibly the entire equipment) in a controlled or regulated manner by a predetermined amount in a given direction (via the dynamometer structure). Typically, a position feedback device is present in this case, which detects the position change caused by the servo drive and feeds it back to the servo drive's control unit. The energy required by the servo drive is preferably derived from the dynamometer training equipment's own energy storage or can be generated by a generator (e.g., an auxiliary generator on the braking device or using a generator as the braking device); the possibility of external power supply via a power line or similar device is also not excluded.

[0047] This invention allows the user on the force gauge to move slowly but noticeably according to their training performance. In this way, the user can clearly perceive the results of their effort, thus encouraging them. This creates a motivating effect that promotes training performance because the user can intuitively perceive what kind of movement they have completed and the amount of exercise achieved based on the movement induced by the actuator. This is suitable for individual users, who can clearly perceive which parts of the predetermined training range they have completed. It is also particularly suitable for enhancing comparisons between multiple users; for example, in a gym, the user with the best training performance can gradually overtake other users with poorer performance. However, if that user regresses and loses their lead, the actuator will stop moving or even move backward to indicate this (while faster users move forward). In this way, whether in a gym studio or a home gym, a competitive spirit can be generated, effectively counteracting the danger of monotony during prolonged use or training.

[0048] Users can immediately and personally perceive their performance in a training task and / or their ranking relative to other participants through this invention, and any improvement (or deterioration) in their training performance will be clearly presented through the adjustment of the actuator.

[0049] This improves the user experience and establishes a tangible comparison with other users (or one's own training performance, such as based on the same user's earlier workouts). This will motivate users and keep exercise enjoyable.

[0050] Preferably, the actuator is controlled in a reversible manner, particularly by a computing unit. This allows the user to not only move forward based on their training performance, but also to move backward. The latter allows the user to clearly understand that their training performance has declined. The user's previous performance, given reference data, or the training performance of other users can be used as a reference.

[0051] Suitablely, the signal unit works in conjunction with an amplifier module designed to consider other parameters of the progress indicator, particularly acceleration and / or speed resulting from training performance. For example, in addition to the position reached, the amplifier module also evaluates acceleration, i.e., the degree of improvement in training performance provided by the user; that is, amplifying the user's recent performance improvement by enhancing the movement of the actuator. This creates a magnifying glass effect, clearly emphasizing the competition for ranking between two users. Even small progress becomes clear through the amplification caused by the amplifier module, thus producing a special motivational effect. For example, if one user lags behind another by 1 meter over a distance of 10 km, the effect on the actuator is almost imperceptible (the positional difference is only 0.1b). However, if the user significantly improves their speed and now manages to lead the others by 1 meter, the amplifier module can emphasize this performance by making a stronger adjustment to the actuator (e.g., by amplifying it 10x or even 50x); if the other user catches up, the same adjustment occurs, or the first user is moved back. This makes the competition for ranking or other small changes clearly visible even over long distances.

[0052] Preferably, the amplifier module is also designed to compress within a time frame. In this case, adjustments can be made not only continuously but also intermittently when necessary. In the case of discontinuous adjustments, for example, if the user has adequate training performance, adjustments are made forward in a pulse-like manner. The resulting acceleration will enhance the user's experience. If the user's training performance stabilizes, a slow reset can be made (unnoticed) so that adjustments can be made forward again in a pulse-like manner later if necessary. In the case of declining performance, a rapid reversal can also be made if necessary.

[0053] Preferably, the actuator is equipped with an end-position detector designed to shut down and / or reverse the actuator when the end position is reached. This avoids exceeding the maximum deflection of the actuator, thereby contributing to the operational safety and / or stability of the force gauge.

[0054] Preferably, the actuator employs a form-fit design. While it is not excluded that the actuator could also operate by force-fit, the form-fit design facilitates precise positioning. In this way, mispositioning due to slippage is virtually avoided, a situation that may occur with friction-locking actuators.

[0055] Preferably, the actuator is arranged between the frame and the support, allowing the frame to move relative to the support. This arrangement integrates the actuator into the support in a space-saving manner. Furthermore, it results in a lower center of gravity. However, on the other hand, it is not excluded to arrange the actuator on a movable frame. This design may be practical if the actuator has a relatively large adjustment path and / or if the actuator includes long guides, particularly telescopic guides.

[0056] Alternatively, the support frame may also be equipped with casters and the actuator may be mounted on the support frame, wherein the actuator drives at least one caster. This caster can be understood as a support foot that allows the support frame to stand on the floor; the support foot referred to here is not a rigid body but a roller. Thus, by driving at least one caster, the force gauge can be moved as a whole with the entire frame by the actuator. Suitably, the actuator may be designed as a slow-moving actuator that drives at least one caster at a low speed below walking speed, preferably not exceeding 1 m / s or at most a safe speed defined by the relevant machine guidelines. This mitigates the danger of the force gauge moving too quickly in a confined environment within a room or building.

[0057] Suitably, all the support legs of the bracket are designed as casters, at least one of which, preferably two, is driven by the actuator. In the case of two driven casters, preferably, one is arranged on the left side of the bracket and one on the right side of the bracket in a longitudinal view.

[0058] Preferably, the actuator has a traction controller for one caster, which preferably feeds back slippage detected on at least one drive caster to the computing unit. Especially on the slippery floors often found in gyms, the operation of the actuator can cause the casters to slip, preventing or only partially achieving the desired longitudinal displacement. The risk of slippage is exacerbated by the fact that when users exert themselves vigorously, sweat or puddles often accumulate in the force gauge area of ​​the floor, making the floor slippery and increasing the risk of slippage. To achieve the desired movement even in slippery conditions, and to facilitate the detection and feedback of slippage to the computing unit, the computing unit is suitably designed to compensate for slippage. Practically, slippage is detected by comparing the movement path generated by the actuator when it is not slipping with the actual movement path traversed. Preferably, multiple casters are driven to compensate for detected slippage. This involves additionally driving the casters that have already slipped to achieve the required slippage compensation.

[0059] Preferably, the casters are spring-loaded. This ensures that even on uneven surfaces (a common occurrence in homes), the casters remain firmly planted on the floor, allowing the actuator to operate with little or no slippage.

[0060] Suitablely, the actuator has a position detection device that feeds back signals to the computing unit. This feedback allows the actuator to reliably set and achieve a precisely defined movement path. For this purpose, the position detection device can be equipped with a sensor designed to detect ground markings. This allows for suitable position detection on the floor of a room or gym.

[0061] Preferably, the floor markings are designed as marking strips, and can also be preferably adhered to the floor surface. Therefore, the desired floor markings can be easily made in any space or room by simply laying the marking strip on the floor and securing it with adhesive if necessary.

[0062] Of particular advantage is that the ground markings are designed as trajectory markers with distance markings. In this way, the distance markings can be used to detect the reached movement path, while the trajectory markers ensure the straightness of the movement path. Ensuring the straightness of the movement path is especially important when multiple force gauges are arranged relatively close together, a situation common in gyms. Aligning the force gauges in parallel can prevent overlapping movement paths, provided that the movement paths of the respective force gauges are straight and without deviation. This can be achieved by using the ground markings as trajectory markers for the respective force gauges.

[0063] Preferably, there can be an alignment module designed to identify and display directional deviations based on floor markings, and preferably also to display the correction direction. Such an alignment module can be used to detect when the actual displacement does not accurately follow the trajectory specified according to the floor markings and to display this deviation to the user. If necessary, the position and / or orientation of the force gauge can then be manually corrected, or the correction can be performed automatically, particularly by driving one of the casters. This correction can be accomplished by monitoring the movement caused by the actuator along a straight line and automatically correcting it if necessary. For this purpose, the correction device preferably acts on at least two casters and controls the casters with a differential speed according to the desired correction effect. This automatically achieves the desired straight-line movement path.

[0064] Preferably, the actuator is provided with a separate power source on the force gauge, particularly an energy storage device and / or (auxiliary) generator. In this way, the force gauge can operate without relying on an external power source. This is a significant advantage, especially for modifications with casters, where there is a risk of the power cable being too short, depending on the distance traveled, or potentially posing a tripping hazard to the user. Wireless power is also an advantage if several force gauges are placed adjacent to each other to avoid mutual interference.

[0065] Practically, the support can be equipped with preferably undriven transport rollers. These rollers allow the user to easily move the force gauge after training to remove it. The transport rollers are preferably arranged in such a way that they only touch the floor when the support is raised to one side, allowing the support to roll, while when the support is fully on the floor, the rollers leave the floor, preventing the support from rolling and keeping it stably in place.

[0066] Specifically, the force gauge can be a bicycle, rowing machine, or treadmill. On the aforementioned two types of equipment, the place of use is a seat. Treadmills, of course, do not have a seat; instead, the place of use is defined as a position on the treadmill where the user is positioned when using it, depending on the structural design. On rowing machines or treadmills, the pedal unit refers to the corresponding operating actuator (rowing handles or a rotating running belt).

[0067] The invention also extends to a corresponding method of operating a dynamometer, particularly controlling the actuator. The invention also relates to a method of operating a dynamometer, particularly a bicycle dynamometer, equipped with an anti-tipping frame, on which a user seat and pedal unit are arranged, and a support bracket carrying the frame and having ground support feet, wherein the pedal unit acts on a braking device. The method includes user operation of the pedal unit, detection of user training performance via sensors, and checking the braking device via a control device connected to the sensors. The invention further analyzes the user's training performance based on training reference data to determine completion, generates a signal for a progress indicator based on the completion, and automatically controls the actuator according to the progress indicator signal, thereby moving the frame with the seat and pedal unit longitudinally in a motorized manner.

[0068] The method also includes exchanging data with other force gauges via a networking unit, particularly training data and / or data for measuring completion. Additionally, training reference data can preferably be generated based on users on other force gauges. These other force gauges can be located locally, for example, in the same networked gym, particularly via LAN, WLAN, or Bluetooth, or remotely networked, particularly via WAN (Wide Area Network) or the Internet. More preferably, the actuators of the respective force gauges can be appropriately adjusted so that the force gauges are positioned according to the user's relative position. Relative placement can be determined by comparing the completion and / or progress indicators of the participating users, optionally including the amplifier module described above. In this way, virtual competition can be conducted with other users on other force gauges. Depending on performance, if a user performs better than other users (achieving a higher completion rate), the actuator can move the user forward, or if the performance is worse, the actuator can move backward, i.e., lagging behind other users. This method allows users to vividly experience this movement, thereby increasing motivation and thus improving training performance.

[0069] In addition, to avoid repeating detailed descriptions of the working method, please refer to the above description of the device, which also applies to the working method.

[0070] Preferably, additional force gauge substations can be added to the device and operating method, exchanging communication signals via a networking unit, such as receiving training instructions and sending corresponding feedback. This networked communication is particularly advantageous when one of the force gauges acts as the master station, for example, a coaching station or exercise management station controls one or more substations where users are exercising.

[0071] The term "exchange" is understood in this article as both one-way and two-way data transmission. Attached Figure Description

[0095] Figure 1a and 1b Taking various types of fitness equipment 1a, 1b, 1c, 1d, and 1e as examples, this illustrates a base or body structure with a unified construction technology, namely, a concealed ( Figure 1a ) and exposed ( Figure 1b The structure of rollers 48, 49, 48', and 49'.

[0096] The fitness equipment 1 includes a drive unit 27 for receiving training performance provided by the user and a force transmission device 21 for transmitting the user's performance during training to the drive unit 27.

[0097] Meanwhile, this invention relates to different types of fitness equipment 1, such as a force gauge 1a, a stationary bike 1a', a recumbent bicycle or recumbent force gauge, a home exercise bike, a rowing machine 1b, an elliptical trainer 1c, a cross trainer 1d, or a treadmill 1e. The fitness equipment 1 is designed as one of the aforementioned different types of equipment 1a, 1a', 1b, 1c, 1d, and 1e. However, the construction technology of the body structure or base of all equipment types 1a, 1a', 1b, 1c, 1d, and 1e is consistent in its structural design, i.e., uniform.

[0098] Figures 1c to 1h Detailed views of the structures of fitness equipment 1 of different types 1a, 1a', 1b, 1c, 1d and 1e are shown.

[0099] The fitness equipment 1 also includes a frame 2, 2a, 2b, on which a drive device 27 and a force transmission device 21 are arranged. The frame 2, 2a, 2b is also designed to support the user of the fitness equipment 1 during exercise. The fitness equipment also includes a support 3, 3' for supporting the frame 2 on the ground.

[0100] The drive unit 27 typically has a controllable braking device through which the user of the fitness equipment 1 can adjust their training load during exercise, or the fitness equipment 1 can specify a training load optimized for training results for the user.

[0101] The force transmission device 21 can be designed differently for different types of equipment 1, such as as pedal units 21, 21a on force gauge 1a or exercise bike 1a', as traction cable 21b on rowing machine 1b, as moving arm on elliptical machine 1c and cross trainer 1d, including moving arms 21c, 21d and pedal arms 21c', 21d', or running belt 21e on treadmill 1e.

[0102] The frame 2 of the fitness equipment 1 or the support 3' formed by two crossbeams 32 and 33 has rollers 48, 49, 48', and 49'. The arrangement of the rollers on the frame 2, 2b or the support 3, 3' prevents the frame 2 from tipping over and keeps it in a fixed position relative to the ground. At the same time, the frame 2 or the frame 2 together with the support 3, 3' can achieve longitudinal displacement X and X' relative to the ground.

[0103] Such longitudinal displacements X, X' of frame 2 relative to support 3 or frame 2 together with support 3' relative to the ground are ensured by at least one actuator 9, and the degree of movement depends on the user's training completion.

[0104] In addition, the fitness equipment 1 is equipped with at least one sensor 26 for detecting the user's training performance and a control device 6 designed to receive data from the at least one sensor 26. The control device 6 works in conjunction with a computing unit 7 designed to determine a so-called completion level based on the training performance provided by the user. The fitness equipment 1 also includes a signal unit 8 designed to generate a so-called progress indicator signal 80 based on the determined completion level, thereby controlling the aforementioned longitudinal displacement X, X' of the frame 2 relative to the support 3 or the frame 2 together with the support 3' relative to the ground.

[0105] Figures 11 to 13 The illustrated embodiment of the force gauge according to the present invention is a bicycle force gauge. However, the present invention is not limited thereto, and can also be applied to other types of fitness equipment or other types of force gauges, particularly recumbent bicycle force gauges, treadmill force gauges, cross trainers and / or rowing machine force gauges.

[0106] like Figure 1i As shown, the bicycle dynamometer according to a first embodiment of the present invention includes a frame 2 as a main component, on which a seat 20 for user use and a handlebar 22 designed in the form of a handlebar are arranged, and a support 3 that supports the frame 2 and on which the frame 2 is arranged in a way that prevents tipping. The support 3 has support feet 4, by which the support can be stably placed on the floor or other suitable surface. In addition, a pedal unit 21 is provided to the seat 20 and arranged so that the user sitting on the seat 20 can operate the pedal unit 21 with his / her legs and support himself / herself on the handlebar 22 in the process. The user applies training performance to the pedal unit 21, which is then received by the pedal unit 21 and fed to the bicycle dynamometer and generally by the braking device 27. In the exemplary embodiment shown, the braking device 27 is designed as a magnetic brake wheel, but other alternative types of braking devices known to those skilled in the art are also available; brake bands or braking devices used as generators are mentioned here as examples.

[0107] The frame 2 can be longitudinally displaced relative to the support 3 by means of the actuator 9, which in the illustrated embodiment (not shown in Figure 1) is mostly concealed. Starting from the center position, as shown in Figure 1, the position of the user on the frame 2 and seat saddle 20 on the support 3 can be changed longitudinally forward (right side of Figure 1) by the actuator 9, and preferably can also be changed in the opposite direction (left side of Figure 1), that is, longitudinally backward.

[0108] exist Figure 2 a and Figure 2 Figure b shows details of the guide for actuator 9. The guide includes a pair of U-shaped guide rails 90 arranged opposite each other on the longitudinal side of bracket 3. "Opposite" here is understood to mean that the open sides of the "U" are both arranged inwards for the guide rails 90 (see Figure b). Figure 2 a) or both are arranged facing outwards (see Figure 2 b). Two rollers run on each side of guide rail 90, one of which is roller 48 ( Figure 2 (Not shown) is not driven, while another roller 49 is driven by the servo motor 94 of the actuator 9. When the actuator 9 drives the roller 49 via the servo motor 94, the roller 49 and the non-driven roller 48 move along the guide rail 90, and the frame 2 thus moves accordingly relative to the fixed support 3.

[0109] Figure 2 a and Figure 2The difference in embodiment b lies only in the orientation of the guide rail 90 and whether the servo motor 94 operates internally or externally. Rollers 48 and 49 may be designed with smooth treads, and the force engagement between the drive roller 49 and the inner side of the guide rail 90 is based on friction; alternatively, at least the drive roller 49 may be optionally designed as a toothed roller, with a corresponding complementary design on the inner side of the guide rail 90, thereby making the driving effect based on form fit.

[0110] exist Figure 3 Figures a and b show another modification of the actuator 9 and its guide. In this case, instead of the guide rail 90, a guide shaft 90' is provided, which is rotated by a servo motor 94. A frame-fixed slider 95 with an internally threaded through-hole 95' is arranged on the shaft 90'. The shaft passes through the slider, and the internal thread 95' engages in the shaft 90'. Therefore, by rotating the shaft 90' by the servo motor 94, the slider 95 and the frame 2 can be precisely adjusted and positioned longitudinally. Rotation in one direction moves the frame forward, and correspondingly, rotation of the main shaft 90' in the other direction moves the frame 2 backward relative to the bracket 3. The shaft 90' can also be concealed, for example, installed inside a U-shaped profile with an inwardly facing opening, such as... Figure 2 As shown in a.

[0111] exist Figure 4 Figures a through c show examples of positions accessible to frame 2 relative to support 3 via actuator 9. The figures show views of frame 2, with the actuator 9 of the force gauge located at the rear (…). Figure 4 a) Middle ( Figure 4 b) and the front ( Figure 4 c) Position. It can be clearly seen how the relative position of the frame 2 and the user seat 20 moves forward or backward relative to the support 3 standing on the base (floor). Typically, the middle position ( Figure 4 b) represents the initial point. Based on Figure 4 b. If the user actively achieves or even exceeds the training objectives, the actuator 9 can directly and forcefully prompt the user by moving frame 2 and the user riding on it forward. Figure 5 As indicated by the right arrow in b. When achieving peak performance or gaining a lead in the race, frame 2 can move completely forward, as shown... Figure 4 As shown in c. Users can receive positive confirmation and motivation regarding their training performance in this way. - On the other hand, if the user's training performance does not meet the expected performance or training goals, the user can be directly and forcefully prompted by moving frame 2 and the user sitting on it backward, such as... Figure 5 The left arrow in b indicates that if no training performance is provided, or if the user remains in last place in the competition, the frame 2 supporting the user will move completely backward, as shown. Figure 4As shown in a. This allows users to be encouraged to improve their training performance in a silent but intuitive way.

[0112] If the user's performance is within the average or expected range, then frame 2 will revert to the middle position, such as... Figure 5 As shown in a. The above process creates a foundation for users to perceive the quality of their training performance by adjusting the appropriate position of frame 2 (and the user on it).

[0113] The following text is based on Figure 6 The block diagram illustrates the schematic structure and functional relationships of the main components. Control device 6 is the central unit for the basic functions of the force gauge.

[0114] Input device 23 and display device 24, which serves as an operation display, are connected to the control device via user interface 25. Furthermore, sensor 26 is arranged on pedal unit 21 and connected to control device 6, which determines the user's training performance through sensor 26. Control device 6 is preferably also designed to use the data determined by sensor 26 to determine signals in order to generate the distance s traveled by the user, the speed v reached, and even, if necessary, acceleration / deceleration a, based on the user's training performance.

[0115] The control device 6 also works in conjunction with the computing unit 7. This computing unit receives signals from the control device 6, particularly signals regarding the user's training performance, distance traveled, speed, and acceleration. The computing unit also receives training reference data signals, such as those set by the user via input device 23. The computing unit 7 determines the degree of completion based on the user's training performance according to the training reference data; the degree of completion can be absolute and / or relative. For this purpose, the computing unit 7 works in conjunction with a signal unit 8, which is designed to generate a signal 80 for the progress indicator 81 based on the degree of completion. The signal 80 is output and relayed as an input signal to the actuator 9, which, based on the signal 80 and the different training performances provided below, moves the frame 2, seat 20, and pedal unit 21 longitudinally in a motorized manner. The computing unit 7 and the actuator 9 constitute the practical core of the invention.

[0116] Actuator 9 is equipped with a servo motor 94, which acts on frame 3 via drive roller 49 to perform displacement. Additionally, a non-drive roller 48 is shown, equipped with a rotation detection device (encoder or resolver) 96. The signal generated by this rotation detection device is a measure of the path traversed by roller 48, and thus a signal of movement of frame 2, which is fed back to actuator 9. Preferably, the rotational speed of servo motor 94 is also monitored, thereby generating a rotational speed signal for drive roller 49. This signal is also fed back to position actuator 9. Position actuator includes a traction controller 93, to which both rotational speed signals of drive roller 49 and non-drive roller 48 are transmitted. This allows determination of whether slippage occurs on drive roller 49 and the degree of slippage. Furthermore, if slippage is detected, appropriate compensation can be made, particularly by actuator 9 additionally controlling the slipped roller 49, and / or, in the case of two or more drive rollers, by the actuators providing complementary control on opposite sides of frame 2 to establish symmetry.

[0117] In addition, the actuator 9 includes limit switches 92 and 92', which are arranged on the guide rail 90. Figure 6 (Not shown in the diagram) In the end region. The limit switch is connected to the actuator 9 via a stop switch device 91. The stop switch device 91 is designed to detect when the rollers 48, 49 approach the corresponding limit switches 92, 92', and then close or reverse the actuator 9. This prevents the frame 2 from shifting excessively, thereby minimizing the risk of the frame 2 dislodging from the guide rail 90.

[0118] The signal unit 8 also works in conjunction with the amplifier module 82. Specifically, signals of speed and / or acceleration determined by the control device 6 based on the user's training performance are additionally transmitted to this amplifier module. These signals can be considered additional parameters for the progress indicator. For example, the user's catching-up range can be amplified based on training reference data and exceeding that data, so that even small improvements are magnified by the amplification module 82 and clearly perceived by the user. This amplification function is applicable if the training reference data is generated by other users on other force gauges 1', especially when two users are competing for ranking. If one user is catching up with another, the amplifier module 82 also makes small improvements during the catch-up more noticeable, i.e., the overtaking force gauge frame 2 is pushed forward by the actuator 9, placing it in a middle position in a tie and then clearly pushing it forward again when the other user is overtaken. Correspondingly, the acceleration provided by the user through their training performance is also amplified by the amplifier module 82. In general, faster users gain a "real overtaking experience" in this way. Conversely, if a user is overtaken by another user, the overtaken user will move backward by the actuator 9.

[0119] Throughout the process, the actuator 9 constantly monitors the adjustment speed of the frame 3 generated by the servo motor 94 through the limiter 98, and limits the adjustment speed to a safe speed that complies with the mechanical instructions in order to avoid the user from being injured.

[0120] Limiter 98 is suitably designed to work in conjunction with servo motor 94 to form a peristaltic drive with an adjustable speed limit of up to 1 m / s.

[0121] In order to provide sufficient power to the actuator 9 and control device 6 or computing unit 7 without relying on the power grid, a separate energy storage device 99 is provided on the frame 2 or bracket 3, which is connected to the actuator 9, control device 6 or computing unit 7 via a power supply line (not shown).

[0122] The energy storage device 99 is designed as a battery and stores the electrical energy required by the mobile frame 2 according to the present invention.

[0123] According to Figure 7 In the modified implementation, the support 3' is not designed as a rectangular frame as in the first embodiment shown in Figure 1, but rather forms a support via two crossbeams 32 and 33. Support feet 4 are arranged at their ends, and the crossbeams 32 and 33 stand on a base, particularly a gym floor, with the aid of these support feet. In this case, the two support feet 4 are designed as casters 42 and 43, each with rollers 49 and 49' arranged at the end of the front crossbeam 33. The rollers 49 and 49' are driven by the actuator 9, as described above, thereby allowing the support 3 to roll. This enables the entire force gauge to move according to the progress indicator signal 80 calculated by the calculation unit 7. The resulting adjustment path is longer, allowing the user to have a more impressive experience based on training reference data when providing training performance. Obviously, as described above, the training reference data can be either absolute values ​​for a set of prescribed training or relative values ​​compared to other users on other force gauges 1'.

[0124] To facilitate communication with other users on other force gauges 1', a networking unit 5 is provided. This networking unit is designed to establish a connection to a data network (specifically the Internet) 50, enabling communication with other users and their force gauges 1'. Other users can be anywhere, whether in the same or another room in a gym, at home, or anywhere else in the world. Virtual competitions can be conducted by exchanging training data with these other users.

[0125] The non-driven roller 48 can be used as a position detection device, and is suitably arranged on another crossbeam 32. In this way, as described in the relevant section of the encoder 96 above, a signal of the actual movement distance can be obtained and fed back to the actuator 9.

[0126] However, alternatively, actuator 9 can also have a trajectory tracking device 97. For example... Figure 7 As shown, the tracking device is designed to track a floor track marker 100 on the floor, which is preferably designed as a linear element and passes through the room where the force gauge is located. If there are multiple force gauges in a room, such as in a gym, multiple floor track markers 100 can be arranged adjacent to each other without intersecting, especially in parallel. The track tracking device 97 has an image sensor 97' for detecting the floor track marker 100. If the image sensor 97' detects a deviation to the left (or right), a corresponding signal is transmitted to the track tracking device 97. This detection function is designed to identify a directional error based on the deviation and determine the correction direction, and display it on the display device 24 if necessary. Furthermore, the display device suitably works in conjunction with the traction controller 93 as a correction device. In this case, the drive roller 49' opposite to the side where the deviation occurred (i.e., the right roller when deviating to the left) is driven by the servo motor 5 at a lower speed to recalibrate the deviation of the force gauge 1 according to the floor track marker 100.

[0127] The ground track marker 100 is preferably designed to be adhesive, for example, designed as single-sided tape. Suitably, distance markers 102 are printed on its top surface, and intermediate markers 103 may also be present. Furthermore, suitably, start-point markers 105 and target markers 106 are also located on the top surface of the ground track marker 100. The ground track marker 100 may be suitably shorter so that a shortened version can be used in smaller rooms commonly found in homes. The edge 101 of the ground track marker 100 serves as a longitudinal guide for the track tracking device 97.

[0128] In addition, the drive rollers 49 and 49' are driven by the actuator 9 in a manner corresponding to the movement of the frame 3 relative to the support 2 in the first embodiment described above.

[0129] If the user exceeds the training reference data (either absolutely or relatively better than other possible virtual competitors on force gauge 1'), frame 3 is moved forward by actuator 9 via drive rollers 49, 49' along ground track marker 100 (see...). Figure 8 a) If the user continues to exceed the training target or exceeds the target target at an extremely high speed or acceleration, and / or surpasses the ranking of another user (competitor) on another force gauge 1', then the force gauge 1 and its frame 3 will continue to be pushed forward via amplifier module 82 so that the user can directly experience the improvement in ranking (see [link]). Figure 8b). Conversely, if the user's performance declines compared to the reference data, or if a virtual competitor surpasses the user, the position actuator 9 reverses accordingly, pushing the force gauge 1 and its frame 2 backward via the drive rollers 49, 49', thus alerting the force gauge to its declining performance and potential drop in ranking (see [link]). Figure 8 c).

[0130] A feature of the second embodiment with drive rollers 49, 49' is that when the user applies a swinging pedal force to the pedals on both sides of the force gauge 1, the left support foot may have a different support force than the right support foot. A related example is... Figure 9 As shown, due to the pushing force exerted by the user on the pedal, the support force on the right side increases compared to the static normal condition (black arrow) (see lightly shaded additional arrow). Correspondingly, on the left side, the dynamic support force generated by the pedal force decreases compared to the static normal condition (black arrow) (see shaded arrow). The different support forces on the left and right sides result in different contact pressures on rollers 49, 49'. Therefore, even if the driving force of the servo motor 94 is the same, different slippage will occur on the left and right sides, causing the force gauge to bias towards the side with the smaller support force. Figure 9 (Left side in the middle). The traction module 82 is therefore suitably designed to recognize the effects of the user's driving force on the pedal push and the resulting slippage differences that cause imbalances, and to control the traction controller to compensate for them.

[0131] Figure 10 and Figure 11 a and b show a modified second embodiment with drive casters. According to... Figure 10 In one embodiment, a drive center roller 47 is provided, which is located on a cantilever between crossbeams 32 and 33. Crossbeams 32 and 33 themselves have sliders 45 on their undersides, the size of which ensures that the center drive roller 47 absorbs at least a majority of the supporting force of the rear crossbeam 32. If necessary, the center drive roller 47 can be designed to be operable to compensate for, for example, directional deviations from the track marker 100 by deflecting the center drive roller 47.

[0132] Optionally, transport rollers 41 can be provided on both sides of the rear crossbeam 32. This arrangement allows the force gauge 1 to be in a position where... Figure 10 In the position shown, the conveyor roller does not touch the floor but is positioned slightly higher. If the force gauge 1 is tilted backward onto the rear crossbeam 32, for example for cleaning, the conveyor roller 41 will contact the ground, allowing the force gauge 1 to be easily rolled.

[0133] According to Figure 11In the modified embodiment of a, the second set of drive rollers 49, 49' replaces the center roller 47 and is arranged on the axle bracket also fixed to the cantilever. This function largely corresponds to... Figure 9 The function compensates for directional deviations (as described above) by selectively driving drive rollers 49, 49' on one side. This function also applies to [other functions]. Figure 11 In embodiment b, the drive rollers 49 and 49' are mounted on a front crossbeam, and the non-drive rollers 48 and 48' are mounted on a rear crossbeam.

[0134] Figure 12 The middle shows Figure 7 A modification. This modification is related to... Figure 7 The difference in the second embodiment shown is the provision of a shape-fitting track marker 100'. This track marker has a rack-shaped toothed portion on its top surface. The tooth profile is preferably rectangular to create a surface that is also easy to navigate in the toothed area. The rollers 48, 48' on the crossbeam are not driven in this case. Instead, the servo motor 94 of the actuator 9 acts on a ratchet 46. A toothed portion complementary to the toothed portion of the track marker 100' is designed on its outer circumference. The ratchet 46 is mounted in the lower region of the frame 2, and the toothed portion on its outer circumference engages with the toothed portion of the track marker 100' in a shape-fitting manner. In this way, a shape-fitting actuator is formed that reliably and precisely moves the frame 2 even when contaminated with liquid (sweat). This modification is particularly suitable for gyms or other sports centers where users can achieve extremely high levels of physical performance.

[0135] This type of use in gyms is Figure 13 The images are shown in different views. Figure 13 Figure a illustrates a plurality of bicycle dynamometers 1, 1' according to the invention arranged adjacent to each other in a gym, with their ground track markings 100 parallel to each other. Initially, the bicycle dynamometers stand side by side, and during training, they are moved by actuators 9 according to the training performance of each user.

[0136] The relative positional relationships are also shown in the diagram. If two users are competing for a ranking (e.g., leading), the amplifier module 82 can emphasize which user is currently leading, even if the lead is only a few centimeters. Therefore, even if the simulated race route is shortened from 10 or 100 km to a typical short distance of 5 to 15 m along a ground track marker 100, the competition for ranking can be clearly experienced. Simultaneously, the invention also employs the following function: when one user falls behind another, it also causes the actuator 9 to reverse, meaning the user lagging in the ranking then moves backward not only relative to others but also in an absolute sense. For example, in... Figure 13As shown in diagram b, the user of force gauge 1 falls behind and is overtaken by the user of another force gauge 1'. This change in relative position is translated by the corresponding actuator 9 into force gauge 1' moving forward and force gauge 1 moving backward. This function is possible whether force gauges 1 and 1' are located in the same place (the indoor cycling room of the gym) or are a certain distance apart (connected only via the Internet 50). This creates a more intense competitive atmosphere and enhances the user's experience, thereby motivating further training performance.

[0137] Figure 13 Figure c shows an example of bicycle dynamometers 1 and 1' aligned on ground track marker 100.

[0138] When multiple bicycle dynamometers 1 and 1' need to be run side by side, alignment is especially important to ensure parallel riding and avoid collisions with adjacent equipment.

[0139] To this end, the trajectory tracking module appropriately works in conjunction with an alignment module to display the deviation detected by the trajectory tracking device 97 on the display device 24, thereby supporting rapid and accurate alignment.

[0140] Figure 14a -e shows a perspective view of different actuators 9. This includes actuators 9 such as those equipped with a rack 61 and a toothed roller 62. Figure 14a ), and an actuator 9 equipped with one or more friction rollers 63 Figure 14b and 14c ), and actuator 9 equipped with rope 64 Figure 14d ) and an actuator 9 equipped with chain 65 Figure 14e Such actuators 9 can be easily housed under the casing of the frame (2, 2a, 2b) of the training equipment 1, thus rarely getting dirty and requiring almost no maintenance. Furthermore, such actuators 9 are inexpensive and reliable.

[0141] Figure 15a -c illustrates other available actuators 9, such as the alternative chain drive ( Figure 15a ), shaft drive 48, 48' equipped with two rollers Figure 15b ) and drives 49, 49' for individual rollers Figure 15c Such actuators are also inexpensive, reliable, and require almost no maintenance.

[0142] The possible positional relationships between the rollers 48, 49, 48', 49' of frame 2 and the support 3 composed of round tube 71 are as follows: Figures 16a to 16c As shown in the image. Figures 17a to 17c This is a schematic diagram showing the possible positional relationship between the rollers 48, 49, 48', and 49' of frame 2 and the bracket 3 composed of C-profile 72 or guide rail 90. Finally, Figure 18a and18b The diagram illustrates the possible positional relationship between the rollers 48, 49, 48', 49' of frame 2 and the support 3 composed of rectangular profiles 73. The rollers 48, 49, 48', 49' of frame 2 can be positioned vertically, horizontally, or diagonally on or within the tubes 71 or profiles 72, 73. A common feature of all the described embodiments is that the user can easily change different types of fitness equipment, for example, by pushing fitness equipment 1 into or placing fitness equipment 1 on the support 3.

[0143] Figures 19a to 19e Showing different types of rollers 48, 49, 48', 49', such as right-angle type ( Figure 19a ), convex type ( Figure 19b ), concave type ( Figure 19c ) rollers or so-called H-type rollers ( Figure 19d ) and so-called L-shaped rollers (19). Various types of rollers 48, 49, 48', 49' are very suitable for specific structures of bracket 3, such as concave rollers for bracket 3 made of round tube 71 or H-shaped and L-shaped rollers for bracket 3 made of rectangular profile 73.

[0144] Figure 20a -d indicates different embodiments of the support frame 3 of the fitness equipment 1, such as a large support frame 74, a telescopic support frame 75 (which can be telescopic in terms of support length and support width), a foldable support frame 76, and a plug-in support frame 77 consisting of assemblies.

[0145] Therefore, the support 3 can be matched by the user with the characteristics of the corresponding equipment type 1a, 1a', 1b, 1c, 1d, 1e. For example, for rowing machine 1b, the support can be extended; for treadmill 1e, the support can be widened.
