Description

[0001] The invention relates to a combination of a lever training device with an optional force analysis option for strength training and analyzing one's own muscle strength. The resistance is provided by the resistance of one's second arm or leg via a rope-mounted training lever. This resistance thus determines the training weight. [State of the art]

[0002] Unlike conventional training equipment that uses resistances such as weights, elastic bands, tension springs, motors, or your own body weight, the training stimulus and training control with the lever training and strength analysis board are provided by the inherent strength of your opposing arm or leg. With minimal technical effort, the user has access to continuously variable training resistances up to their maximum strength, depending on their performance level, without having to manually adjust weights, elastic bands, or springs, or electrically adjust the motor settings for the exercise. During training, forces can also be measured and analyzed using software for all exercises.

[0003] The inventor's utility models DE 20 2016 001, DE 20 2016 001 965, DE 20 2018 005 655, and DE 20 2019 004 983 describe the basic principles of this new application. In contrast to the other utility models, the lever training and strength analysis board according to the invention builds strength via a rope-fixed training lever rather than cable pulleys. This further simplifies the design. The board can be used multifunctionally for strength training, but in addition to performing conventional strengthening exercises, the lever bar also offers many new rotation variations that are only possible with the special rope fixation and the lever bar. In addition, pulling exercises from “above” (above head / body level), which can otherwise only be trained on significantly larger, non-mobile devices, can be effectively implemented on the compact design of the lever training and force analysis board using an optional pulley bar. [Task of the invention]

[0004] For strength training, the user always uses their opposite legs or arms, utilizing the decreasing (eccentric) counterforce of the other arm or leg, thus controlling their load. At the same time, the lever training and strength analysis board is designed to allow physiological rotational movements as a modification of conventional strength exercises that are difficult or impossible to train on conventional strength training systems. A simple and flexible design ensures mobility, allowing for quick setup, adjustment, and disassembly for different exercises, depending on the user's physical condition. An optional force sensor monitors the applied load values during the movement sequence.

[0005] The lever training and force analysis board preferably consists of a training plate (1), usually lying on the floor, which the user can use to stand or sit on, or as a step or pressure-distributing plate on the body during exercise. The training plate preferably has three through-holes (10, 11, 12) through which an adjusting cable (2) is threaded, and preferably three larger through-holes (13, 14, 15) for inserting / storing the lever rod (7) and the cable deflection rod (21). The through-holes (13, 14, 15) can also be used to secure the balance hemispheres (6) under the training plate (1). On the adjusting rope (2) there is preferably a brake loop (4) at one end, which is inserted from above through the training plate (1) via the through hole (11) in such a way that this brake loop (4) makes it possible to insert the second end of the adjusting rope (2) underneath the training plate (1).The second end of the adjusting rope (2) preferably runs from above via the through-hole (10) through the training plate (1), under the training plate (1), through the brake loop (4), from below through the through-hole (12) and upwards onto the training plate (1). The lever rod (7) can preferably be hooked into the length-adjustable training loop (3) thus created in the adjusting rope course above the training plate (1), preferably via an openable and closable rope fastener (16) with a reduction and safety ring (20). The rope fastener (16) preferably runs in a loop with a knot (19), which then passes through a reduction and safety ring (20). While the knot (19) forms one end of the rope fastener (16), it is inserted through the other end in such a way that the rope fastener (16) can be easily closed or opened.The rope lock (16) is preferably firmly fixed to the adjusting rope (2) by passing the adjusting rope (2) through a fixed loop (17) on the rope lock (16) that is separated by the reduction safety ring (20). The second locking loop (18) on the rope lock (16), which is easily opened and closed via the knot (19), enables quick connection or release to the lever rod (7), while the fixed loop (17) created via the reduction safety ring (20) holds the rope lock (16) to the adjusting rope (2) or, alternatively, can accommodate a force measuring sensor (23) on one side, while the other side of the force measuring sensor (23) is held directly by the adjusting rope (2) by means of a hook.When connecting the rope lock (16) to a lever bar (7), the part of the locking loop (18) of the rope lock (16) without the knot (19) is passed through the screw eyelet (8) firmly attached to the center of the lever bar (7), while preferably the other part of the locking loop (18) with the knot (19) is placed once around the lever bar (7). The screw eyelet (18) therefore preferably only serves as a fixator and not for direct force absorption when the lever bar (7) is pulled. The further course of the adjusting rope allows an automatically pre-set length to be firmly fixed, preferably by pulling on the lever bar (7), since the adjusting rope (2) is then automatically clamped under the training plate (1) via the brake loop (4). A force measuring sensor (23, . Fig. 1b). The adjustment rope path allows the training loop (3) to be either lengthened or shortened with the lever rod (7) by pulling on the adjustment rope end (5) above the training platform or on one side of the relieved training loop (3) without pulling on the lever rod (7). The lever rod (7) is preferably adjusted to the appropriate training height and to the body size of the user (24). The rope fastener (16) also allows various other action elements besides the lever rod (7), such as handles, foot straps or the like, to be connected to the training plate (1) via the adjustment rope (2). The lever rod (7) can preferably have grip balls (9) attached to it via through-holes at its ends and to these via short ropes (25). The grip balls (9), preferably attached to the lever rod (7) in this way, enable further grip and exercise variations.At the end of the adjusting rope (2), at least one balance ball segment (6) is preferably threaded onto it. This fits from below into one of the three through-holes (13, 14, 15) in the training plate (1), thus creating a movable, rocking surface for training while standing on the training plate (1). The through-holes (13, 14, 15) in the training plate can be used to store the lever rod (7) vertically and within easy reach by inserting it from above. A further function of the through-holes (13, 14, 15) is to accommodate the rope deflection rod (21). Fig. 1d) by plugging it in. When using the rope deflection rod (21), the training loop (3) of the adjusting rope (2) runs over the upper deflection pins (22) to the right and left of the rope deflection rod (22). The lower deflection pins (22) fix the rope deflection rod (21) to the training plate (1). Fixing the lever rod (7) via the adjusting rope (2) and rope lock (16) to the rope deflection rod (21) allows for special pulling exercises, especially from above, on the lever training and strength analysis board.

[0006] The problem is primarily solved by a device according to the features of the first claim. Advantageous embodiments and further developments are the subject of the dependent claims.

[0007] According to the invention, the lever training and strength analysis board consists of a training plate on which the user can stand or sit for their exercises, use it as a step, or use it as a pressure-distributing plate on the body. The body parts or muscle groups to be trained are trained using action elements, such as a lever bar, foot loop, or other force-transmitting handles or pulling elements, which are connected to the training plate via an adjusting cable. Optionally, the lever training and strength analysis board can be supplemented with an additional deflection bar, which can be flexibly attached to the training plate. This allows the adjusting cable to be redirected so that the user can alternatively perform exercises with pulling from above. Another optional addition is balance ball segments, which can be attached underneath the training plate and thus create a rocking, moving surface for standing exercises on the training plate.

[0008] The basic training principle of using the lever training and strength analysis board is characterized by the fact that while one arm or leg works concentrically, meaning the targeted (innervated) muscles actively shorten, the opposing arm / leg counteracts the movement by decreasing (eccentric) force. The decreasing (eccentric) force is considerably greater than the shortening (concentric) force, which in turn is primarily responsible for hypertrophy, i.e., an increase in muscle cross-sectional area, and thus for improved performance. The side with the decreasing (eccentric) force controls the training stimulus for the opposite side. This enables training up to the user's maximum strength. Since at least one action element is firmly attached to the training plate, static, holding (isometric) strength exercises can be performed in addition to dynamic strength exercises, preferably using the lever bar.The trainee tenses the muscles at a specific joint angle and maintains the applied force for a certain period of time. A particularly characteristic feature of the lever training and strength analysis board is the use of the lever bar as an action element. This allows for not only the classic, well-known, dynamic strength exercises, but also new rotation variations. The classic, vertical up and down movements can also be rotated in all directions using the lever bar, which is only fixed vertically to the adjusting rope. This makes all dimensions of movement possible with self-controlled, optimal resistance. The lever bar acts on the centrally fixed adjusting rope like a seesaw or scale, transferring the force without loss in the vertical movement via the pivot point from the left side (e.g. left arm) to the right side (e.g. right arm) and vice versa.The key here is the flexible vertical fixation of the lever bar via the adjusting cable, as this allows the lever bar to remain freely movable in all other directions. The free rotating movements thus enabled strengthen the muscles in a new way along all their physiological axes. The variations, from classic vertical execution to rotations within an exercise sequence, flow seamlessly into one another without interruption, adjustment, or weight adjustment.

[0009] Another variation for a greater training stimulus is eccentric training with decreasing negative force that exceeds the muscle's own holding strength. Here, different muscle groups with different strengths are combined. For example, stretching the legs can train the counter-holding biceps beyond their maximum holding strength into negative decreasing force (arms cannot hold the force generated by the legs and decrease) and so increase maximum strength. The training plate is used, for example, as a step. For special applications, the lever bar can be used to increase or decrease loads on the same muscle groups, for example on the right or left arm flexor, by using different grip positions. The bar acts as a lever via the tipping point on the adjusting rope according to the law of the lever. The grip position closer to the tipping point requires more force during training.By using an optional rope deflection rod, which can be additionally fixed in a hole on the training platform, the lever training and force analysis board becomes a small, portable cable pull tower that allows pulling exercises from above.

[0010] Small balance ball segments, preferably hemispheres, are threaded through a hole onto the end of the adjustment rope and can optionally be fitted with a floor protector on the flattened section. They can be secured under the training platform in designated holes above the rounded section. This creates a flexible tilting function for the training plate, which additionally stimulates the user's deep muscles and trains balance skills during standing exercises.

[0011] To improve grip strength and for even more variable exercise sequences, various action elements such as handles, grip balls or foot straps can be attached, preferably to the two outer ends of the lever bar.

[0012] A force measuring sensor, optionally suspended between the fixing adjustment rope and the action element, such as a lever bar, can record and display the current force value for all exercise variations and optionally analyze it via an additional APP provided with corresponding reference values.

[0013] On the lever training and strength analysis board, the same muscle groups and different muscle groups that have approximately the same range of motion can work against each other (e.g. right arm to left arm, arms pulling against the left or right extending leg, both legs stretching against the holding arm force).

[0014] A particularly characteristic feature of the invention is the easy adjustment of the automatically fixing adjustment rope. In order to be able to change the length of the fixing adjustment rope for different exercises and body sizes, it is flexibly and force-lockingly connected to the training plate of the lever training and strength analysis board. The adjustment rope is able to continuously adjust the action element, preferably the lever bar, to any training height. This is preferably achieved by relieving the load on the action element, e.g. the lever bar. This automatically releases the fixing adjustment rope so that it can be continuously pulled back or retracted to any length. When the lever training and strength analysis board is loaded, i.e. by pulling on the action element, such as the lever bar, the fixing adjustment rope is firmly fixed in a selected position / height due to its specific course, preferably under the training plate.The adjustment rope is designed so that it passes through three holes in the training plate and automatically tightens itself via a loop of the adjustment rope below the training plate as soon as upward force is applied to the preferably suspended lever bar. However, its length can then be easily adjusted again when the load is removed. This allows training in any desired body position. The training plate contains at least one opening or hole for the routing and height adjustment of the fixing adjustment rope.

[0015] To achieve a simple setup, the following items are part of the lever training and strength analysis board: Each board preferably has one action element, preferably a lever bar, which can be hooked into the fixing adjustment cable. The action element is held by at least one fixing adjustment cable, which is preferably inserted from below through the training board through at least one opening or hole. If necessary, a force sensor can be hooked into the force flow between the action element, preferably the lever bar, and the fixing adjustment cable. The lever bar can also be equipped with additional action elements at its ends, such as handles, grip balls, or foot loops, which are preferably attached to the lever bar by short cables and through holes.The adjustable rope preferably runs beneath the training plate and is either automatically secured to the ground when the user steps onto the plate, can be knotted, mechanically clamped in some other way, or preferably automatically tightens itself as soon as a tensile load is applied to the adjustable rope. If the adjustable rope is not secured, it can be continuously adjusted to any length required for the exercise. This brings the attached action elements to the appropriate height, allowing the user to easily perform the desired exercise.

[0016] The training plate is suitable for standing or sitting on, as a step, or as a pressure-distributing plate on the body during exercises. It is ideally large enough to be easily transported due to its compact size and weight. Holes or holes on the training plate are preferably used to guide and secure the adjustment rope, insert / store the lever bar, secure the rope deflection bar, or hold the balance ball segments during training.

[0017] The physiologically designed lever training and strength analysis board offers users all the essential exercises for strengthening and analyzing the muscles of the entire body. More than 25 common training exercises for all major muscle groups are available in classic versions, and for most, at least two additional rotation variations are possible.

[0018] A selection of training exercises are available in different body positions: Shoulder front raises, scoops, shoulder press, pull-ups from above, pullovers, tricep curls, bicep curls, rowing, standing / seated bench press, side abdominal exercises, standing butterfly, leg curls, hip extensions, deadlifts, and much more

[0019] Using evaluation software, e.g., an app, a force sensor that can be inserted between the action element and the adjustment rope can record values to assess muscle performance and identify imbalances, and process the data according to the implemented software. This means that, with the optional addition of a force sensor, the system not only performs various training functions but also offers extensive analysis functions. This allows the strength values to be visualized, analyzed, and later statistically evaluated. This allows trainees to more precisely adjust their current performance through the measurement and visualization of their strengths, thus making it easier to set comparable training stimuli during the current training session and / or at subsequent training sessions, or to increase training in a controlled manner, provided previous data has been recorded and saved in a database.

[0020] In addition to the analysis values and the current strength, additional training-relevant content such as rest times, repetitions, force progressions, exercise content, training position data, etc. can be conveyed, preferably via an app. The maximum strength analysis with the optionally used force measuring sensor on the lever training and force analysis board can be carried out statically, while holding, or dynamically in motion before each exercise, or as a force analysis by comparison with reference values. The action element, preferably a lever bar, is fixed in place via the fixing adjustment rope at the appropriate length for the exercise using the force-locking adjustment rope clamp. For each exercise, there are prescribed body positions that are achieved by appropriately adjusting the adjustment rope. These values are then used for training control and can be transferred to a computer system.While in static maximum strength measurement, force is built up against a fixed, insurmountable resistance, in dynamic / isokinetic maximum strength measurement, the movement is slowed to the slowest possible speed by eccentric counter-force. The corresponding opposing arm or leg takes over the force control, with a slow, opposing concentric movement of the other leg or arm just barely possible in the maximum range. [Examples]
