Description

Device for performing physiologically correct physical exercises

[0001] The present invention relates to a device for performing physiologically correct physical exercises. Object of the invention

[0002] The present invention aims to support users in the physiologically correct execution of physical exercises and to minimize the risk of injury associated with such exercises.

[0003] Furthermore, a compact and cost-effective training device should be provided, which should be modular and expandable with additional functions.

[0004] Further tasks of the invention will become apparent from the following description. Description of the invention

[0005] One object of the invention is solved by a device for performing movement sequences or bodyweight exercises, comprising a base body with a support side for mounting the base body on a surface and with a footboard facing away from the support side for supporting a user's foot, wherein the footboard comprises at least a first section for receiving a ball of the foot and a second section for receiving a heel of the foot, wherein the first section and the second section are inclined relative to each other and are spaced apart from each other at least section by a convexly shaped third section.

[0006] When used as intended, the user positions the device with its support surface on a surface, particularly the floor, and then places their feet on the footplate of the device in such a way that the balls of their feet, or the toe pads forming the respective balls of the feet, are supported on the first section of the footplate, while the heels of the feet are positioned in the second section. The two feet are thus essentially The two sections are arranged parallel to each other on the footing side. Because the first and second sections are inclined towards each other, the user assumes a position similar to standing on tiptoe.

[0007] By moving their feet towards each other, the user assumes a position in which the outer edges of the feet are in contact with the first and / or second section of the footplate, while the longitudinal arches of the feet are supported by the convex third section of the footplate. This position is particularly advantageous for the physiologically correct execution of movements or bodyweight exercises. Specifically, this position allows for smooth and joint-mechanically correct movement without requiring the user to balance on their toes.

[0008] In this position, a squat can be performed, for example, by externally rotating both hips without risking hip impingement (also known as femoroacetabular impingement syndrome or FAIS). The body weight is transferred to the device via the balls of the feet through the incline between the first and second sections, and the convex third section facilitates external rotation and prevents unwanted internal rotation of the hips. This reliably avoids a valgus position, in which the knee is bent medially (inward).

[0009] The device according to the invention thus supports the user in the correct execution of physical exercises.

[0010] According to a preferred embodiment of the device according to the invention, the first section and the second section are inclined to each other at an angle α between 0° and 90°, preferably between 10° and 50°, particularly preferably between 20° and 40°, and especially at an angle of 30°.

[0011] This angle has proven particularly advantageous for the safe and physiologically correct execution of bodyweight exercises. An angle of approximately 30°, chosen as the average of the range of motion (ROM) of the ankle joint, is especially beneficial. An inclination according to this design allows the user to assume a position that facilitates control of leg axis rotation, thus compensating for valgus and varus misalignments of the knee joint.

[0012] According to a further preferred embodiment of the device of the invention, it is provided that the first section is divided by a first circular ring, in particular by a partial section of a first circular ring, and / or the second section by a second circular ring, in particular by a partial section of a second circular ring.

[0013] This design makes the footplate particularly compact and ergonomically optimized. Furthermore, the design of the first and / or second section as segments of a circular ring encourages the user to position their feet close together, ensuring that the balls of both toes are supported on the first section. This automatically results in a particularly stable and advantageous position for the user on the device, as the close spacing of the feet automatically positions their longitudinal arches against the convex third section.

[0014] According to a further preferred embodiment of the device according to the invention, the first circular ring and the second circular ring are inclined at an angle α to each other.

[0015] In this embodiment, the first and second sections, in addition to the annular subsection, can have further subsections, for example, flat or uneven, even or odd. Because the annular subsections are inclined relative to each other at an angle α, the advantages described above can also be achieved in such embodiments. In particular, the angle α can be 30°. By combining this specific inclination with the ergonomically advantageous design (of the subsections intended for supporting the ball of the foot and heel) of the first and / or the second section, a particularly user-friendly and ergonomic design of the device according to the invention can be achieved.

[0016] According to a further preferred embodiment of the device according to the invention, it is provided that the first section and the second section enclose the third section.

[0017] This embodiment has proven particularly advantageous, especially because it accommodates various foot deformities. For example, the user can position their feet slightly angled relative to each other, or at an angle to a symmetry or longitudinal axis of the device on the walking surface. This makes the device more versatile and also results in a particularly compact design.

[0018] According to a further preferred embodiment of the device according to the invention, the third section is formed by a spherical surface, in particular by a partial section of a spherical surface.

[0019] This allows for particularly stable and reliable support of the user's feet in the area of ​​the longitudinal arches. In particular, the design of the third section as an approximately hemispherical surface enables especially comfortable and user-friendly handling. Furthermore, injuries that could be caused by any sharp edges or points on the third section are reliably prevented.

[0020] According to a further preferred embodiment of the device according to the invention, it is provided that the second section overhangs the first section and the third section at least partially.

[0021] Since the second section in this embodiment extends vertically beyond both the first section, which supports the balls of the feet, and the third section, which supports the feet in the area of ​​the longitudinal arch, a particularly comfortable and ergonomic positioning and orientation of the feet on the walking side of the device is possible. Furthermore, the feet can be positioned particularly stably and securely on the walking side without pressure points or the like arising.

[0022] According to a further preferred embodiment of the device according to the invention, it is provided that the third section overhangs the first section at least partially.

[0023] Because the third section, which supports the feet in the area of ​​the longitudinal arch, extends vertically beyond the first section on the footbed, which supports the ball of the foot, the device achieves particularly efficient stabilization of the knee joint when used as intended. This further reduces the risk of injury during standing exercises and provides even more effective support for the user in performing such exercises in a physiologically correct manner.

[0024] According to a further preferred embodiment of the device according to the invention, it is provided that the base body has a connecting section on its support side for creating a detachable connection between the base body and a base body of the device.

[0025] This allows the device to be modularly expanded by adding a base body, which can fulfill different tasks or have different functionalities. Because the connection to the base body is provided on its contact surface, the device's design and structure can be kept simple, and in particular, the design of the footplate can be fully optimized for providing the best possible support to the user in the correct and injury-free execution of exercises, without having to consider the possibility of creating a detachable connection between the base body and the footplate. Overall, this creates the possibility of versatile use for the device according to the invention.

[0026] According to a further preferred embodiment of the device according to the invention, the connecting section is designed in such a way that a positive locking connection with the base body is enabled.

[0027] In particular, the positive-locking connection should be designed, or the connecting section shaped, in such a way that rotation of the base body and the main body is impossible as long as they are connected. This offers the advantage that the relative position of the base body and the main body cannot change, especially during the intended use of the device by the user when performing physical exercises. Furthermore, this also creates the possibility of connecting the base body to the main body in a specific rotational position. Since this makes the device more versatile, user-friendliness is increased in such embodiments.

[0028] According to a further preferred embodiment of the device according to the invention, the connecting section is formed by a polygonal recess in the base body.

[0029] In this way, the connecting section can be designed to be particularly simple and cost-effective in order to fulfill the functions outlined above.

[0030] According to a further preferred embodiment of the device according to the invention, the device comprises a base body, wherein the base body has a connecting element for creating a detachable connection of the base body with the main body and means for fastening the base body to a substrate or to a wall.

[0031] The connecting element can be designed to engage with the connecting section of the base body. The connecting section and / or connecting element can also include additional connecting means, such as magnetic connectors, to improve the detachable connection between the base body and the base element. The means for attaching the base body to a surface, such as the floor or a wall, allow the base body to be mounted to the surface or wall for secure storage or safekeeping of the device, preferably permanently, for example by means of screws, and allow the base element to be detachably connected to the mounted base element when the device is not in use for its intended purpose of performing physical exercises.For this purpose, the base body may have holes through which screws can be inserted to fasten the base body to the substrate or wall.

[0032] According to a further preferred embodiment of the device according to the invention, the base body is formed by a polygonal mounting plate corresponding to the polygonal recess of the base body.

[0033] This mounting plate can be designed to be fully or substantially fully accommodated within the polygonal recess of the base body. This results in a particularly compact design of the device, while the mounting plate provides a simple and efficient way to store the device when it is not being used as intended for performing physical exercises.

[0034] According to a further preferred embodiment of the device according to the invention, the device comprises a base body, wherein the base body has a connecting element for producing a detachable connection of the base body with the base body as well as means for receiving resistance bands.

[0035] This type of base unit allows the device to be combined with resistance bands, thus expanding the range of training options. Because the means for attaching the resistance bands are located on the base unit rather than on the base unit itself, the base unit's design can be kept as simple as possible.

[0036] According to a further preferred embodiment of the device according to the invention, it is provided that the means for receiving resistance bands are provided by a profiled underside of the base body is formed, which underside is preferably facing away from a top side of the base body, on which top side the connecting element is arranged.

[0037] The profiled underside of the base provides a particularly simple and cost-effective, yet highly effective and versatile way to use resistance bands in bodyweight exercises. Because the resistance bands can be attached to the underside of the base, there is no need to secure them separately against accidental release – this securing mechanism is automatic, as the base is subjected to the user's weight during normal use. This simplifies handling and significantly improves the device's user-friendliness. Furthermore, this design allows the use of resistance bands without any additional equipment.

[0038] According to a further preferred embodiment of the device according to the invention, the device comprises a base body, wherein the base body has a connecting element for producing a detachable connection of the base body with the base body and at least one force sensor, preferably several spaced-apart force sensors, for measuring forces transmitted to the base body via the base body.

[0039] By means of a force sensor, preferably several, for example four, force sensors, which can be arranged in pairs on opposite radials of the, preferably disc-shaped, base body and equidistantly in or on the base body in the circumferential direction, it becomes possible to analyze the performed exercises. Forces acting on the base body during the intended use of the device can thus be detected, recorded, displayed with spatial and temporal resolution, and compared, for example, with an ideal or predefined force profile. This provides the user with data that allows them to identify and correct faulty or problematic movement patterns.To ensure the most accurate data recording possible, the base body may be made of hard plastic reinforced by a metal frame.

[0040] According to a further preferred embodiment of the device according to the invention, the base body has a communication device, which is used to transmit measurement data. at least one force sensor, preferably all force sensors, is connected to a user's terminal device.

[0041] This embodiment makes it possible to integrate the device into the "Internet of Things" (IoT). IoT refers to a network of interconnected objects and devices (also called "things") equipped with sensors, software, and other technologies to transmit and receive data to and from other things and systems. In particular, data acquired by the device, preferably sensor data from the force sensors, can be received, evaluated, stored, and further processed by external devices. This allows for even greater improvement in the training success and progress achievable with the device.

[0042] According to a further preferred embodiment of the device according to the invention, the base body has a further connecting section for producing a detachable connection of the base body with a further base body, wherein the further connecting section is preferably formed on a bottom side of the base body, which bottom side is preferably facing away from a top side of the base body, on which top side the connecting element is arranged.

[0043] This allows the base body to be detachably connected to the main body via its upper surface or the connecting element provided there, while the base body can be detachably connected to the second base body via its underside or the additional connecting section provided there. In this way, the base body can be connected, for example, to another base body that has a profiled underside, enabling the device to be used with resistance bands. Alternatively or additionally, the base body can be detachably connected to another base body, which is formed by a polygonal mounting plate corresponding to the polygonal recess of the main body.

[0044] The described base bodies can also be used together with base bodies that are not designed according to the invention. In particular, the combination of a (any type of) base body with one of the base bodies described above can enable the safe, reliable and easy-to-handle storage of the base body, the connection and use of other aids, such as resistance bands, the analysis of the movement sequences performed on the base body and / or the integration into the IoT.

[0045] Thus, the invention also includes a device which comprises at least a base body according to one of the described embodiments and a base body which comprises at least a support side for mounting the base body on a substrate and a footboard side facing away from the support side for supporting at least one foot of a user.

[0046] This allows all of the advantages explained above in connection with the base body to be realized. Brief description of the characters

Ways to implement the invention

[0048] Figures 1 to 6 show a base body 1 of a device according to the invention in a first embodiment. The base body 1 has a support side 2, with which the base body 1 can be placed on a surface, and a footplate 3, which, when the device is used as intended by a user, serves to position the user's feet in a manner advantageous for the physiologically correct execution of physical exercises.

[0049] The tread side 3 has a first section 4, which has the shape of a circular segment, and a second section 5, which also has the shape of a circular segment. However, the second section 5 is not coplanar with the first section 4, but lies in a plane that is inclined at an angle α to a plane of the first section 4. In the illustrated embodiment, the plane of the first section 4 is essentially horizontal, while the plane of the second section 5 is inclined at an angle α of approximately 30° to the horizontal (see Fig. 4).

[0050] In the illustrated embodiment, the first section 4 and the second section 5 are separated section by section by a convexly shaped third section 6. spaced apart, with the third section 6 essentially having the form of a subsection of a spherical surface.

[0051] A connecting section 7 is provided on the support side 2, which has a substantially flat contact surface and on which the base body 1 rests on the ground when the device is used as intended. In the illustrated embodiment, the connecting section 7 is formed by a polygonal recess (in the form of a dodecagon) in the base body 1. In the area of ​​this recess, the base body 1 also has a magnet 16, which serves to facilitate the detachable connection of the base body 1 to a base body 8.

[0052] A first base body 8a, 8 is shown in Figures 7 to 11. In this embodiment, as a polygonal mounting plate corresponding to the polygonal recess of the base body 1, the first base body 8a primarily serves to securely store the device when it is not being used as intended for performing physical exercises. The mounting plate can be attached to a surface, particularly a wall, preferably by screwing it in place. To securely store the base body 1, it can be connected to the first base body 8a, 8 by sliding the base body 1 onto the first base body 8a, 8, which is designed as a mounting plate, using its connecting section 7. A magnet provided in or on the first base body 8a, 8 can facilitate the detachable connection between the base body 1 and the first base body 8a, 8.

[0053] Figures 12 to 16 show a second base body 8b, 8 with a top surface 11, on which a connecting element 9 is provided, and with a profiled underside 10, which underside 10 is designed to receive resistance bands. The connecting element 9 can essentially correspond to the mounting plate shown in Figures 7 to 11. The profiled underside 10 has a plurality of channels 17 into which a resistance band can be inserted. The channels 17 can, as in the illustrated embodiment, form a mirror-symmetrical profile of the underside 10, so that the user can work with resistance bands attached to opposite sides of the second base body 8b, 8.

[0054] Figures 17 to 21 show a third basic body 8c, 8 with a top surface 15 and a bottom surface 14, which is similar to the second basic body shown in Figures 12 to 16. 8b, 8 - on its upper side 15 again includes a connecting element 9 for connecting the third base body 8 with the base body 1.

[0055] Furthermore, the third base body 8c, 8 includes on its underside 15 a further connecting section 13 for making a detachable connection with another base body 8, in particular with the first base body 8a or the second base body 8b.

[0056] Thus, for example, it becomes possible to arrange the third base body 8c, 8 between base body 1 and second base body 8b, 8, whereby a detachable connection can be made with both the base body 1 and the second base body 8b, 8 (see Fig. 22).

[0057] The third base body 8c, 8 further comprises force sensors 12, which enable the force sensors 12 to measure forces transmitted via the base body 1 to the third base body 8c, 8. Preferably, the third base body 8c, 8 comprises – as in the illustrated embodiment – ​​several spaced-apart force sensors 12 in order to allow the most accurate and informative analysis possible of the movements performed by the user on the device.

[0058] Possible ways of using the device according to the invention are shown in Figs. 23, 24 and 25.

[0059] Fig. 23 shows the use of the device for performing squats with a resistance band (left) and upright rows (right). The device comprises the base body 1 and the second base body 8b, 8, which is detachably connected to the base body 1. Two resistance bands 18 are attached laterally to the second base body 8b, 8, and the user holds these resistance bands 18 with their left and right hands. The device rests on the floor (not shown) via the underside 10 of the second base body 8b, 8.

[0060] Fig. 24 shows the user using the device for deadlifts, with the user using a resistance band 18 attached to the front of the second base body 8b, 8, which the user holds with both hands. The device corresponds to the device shown in Fig. 23 and is also supported on the floor (not shown) via the underside 10 of the second base body 8b, 8.

[0061] Fig. 25 shows the user performing squats, using only the basic body 1 without any additional base bodies 8. Base body 1 is supported on the floor (not shown) with its support side 2. To reach the starting position, the user places both feet on the footplate 3 of base body 1 (Fig. 25, left). Throughout the entire movement sequence (Fig. 25, center), the position of the user's feet on the footplate 3 does not change (Fig. 25, right).

[0062] When used as intended, the user positions their feet on the platform 3 of the device such that the balls of their feet, or the toe pads forming the respective balls of the feet, are supported by the first section 4 of the platform 3, while the heels of the feet are positioned in the second section 5. The two feet are arranged essentially parallel to each other on the platform 3. Because the first section 4 and the second section 5 are inclined relative to each other, the user assumes a position similar to standing on tiptoe.

[0063] By moving his feet towards each other (or by positioning his feet accordingly when entering the step surface 3), a position is assumed in which the feet are in contact with the first section 4 and / or the second section 5 of the step surface 3 in the area of ​​the outer edge of the foot, but the feet are supported in the area of ​​the longitudinal arch on the convex third section 6 of the step surface.

[0064] This position is particularly advantageous for the physiologically correct execution of movement sequences or bodyweight exercises. In particular, this position allows for smooth and joint-mechanically correct movement without the user having to balance on their toes. For example, a squat can be performed in this position by externally rotating both hips without risking hip impingement (also known as femoroacetabular impingement syndrome or FAIS). The body weight is transferred to the device via the toes through the incline between the first section (4) and the second section (5), and the convex shape of the third section (6) enables external rotation and prevents unwanted internal rotation of the hips. This reliably prevents a valgus position, in which the knee is bent medially (inward).

[0065] The device according to the invention thus supports the user in the correct execution of physical exercises.
