Abstract
Description
[0001] The invention relates to a training device for training individual, specific muscle groups in the upper body, wherein during training a seat is moved relative to an upper body support element against a counterforce acting in at least one direction of movement.
[0002] A large number of training devices for different muscle groups in the human body are already known. However, training multiple muscle groups simultaneously has the disadvantage that only some of these muscle groups generate the majority of the force required to perform the movement, and thus other muscle groups are not stimulated and trained with sufficient intensity.
[0003] However, a lack of sufficiently trained, deeper muscles repeatedly leads to serious health problems, as the joints are not adequately supported by the muscles. This is particularly relevant for the muscles in the upper body, such as the back muscles, which support the spine. The lateral and anterior muscles of the upper body are also important, as these muscles work together to provide overall support for the upper body. For good spinal support, it is particularly important that the deep muscles close to the vertebrae are sufficiently developed. In addition to the back muscles, the deeper, smaller, lateral, and anterior muscles should also be adequately trained.
[0004] To ensure training of smaller muscles in particular, targeted training for a single, specific muscle group has proven effective. Since targeted training prevents compensation from other muscles, targeted muscle building near the joints can be ensured. Targeted training also has advantages for injured individuals who cannot train all muscles to the same extent.
[0005] Essentially, the joints in the body act as pivot points around which other body parts, such as bones, are moved by the muscles in a pendulum-like manner. An example of this is the elbow joint, around which the forearm can move like a pendulum. The pelvis can also move in this manner around the individual vertebrae of the spine. The pelvis can thus move along a curved path, pendulum-like, around one of the vertebrae.
[0006] In order to adequately stimulate the muscles at various joints that are particularly important for health, such as the hip joint or individual vertebrae of the spine, the goal of training is to create the resistance against which the muscles must work as close to the joint as possible, i.e., to generate resistance close to the pivot point. This trains the muscles that surround and protect the joint.
[0007] For the specific training of muscles surrounding the joints, state-of-the-art training devices for the leg muscles, the hip muscles or the muscles in the lumbar region are known.
[0008] A training device for the core muscles is described in DE 9405749 U1. The legs are fixed so that the upper body, which rests on an air-filled ball, can be lifted against its own weight. Depending on the position of the person exercising, different muscle groups are engaged. Unfortunately, the deep muscles of the hip joint are not specifically targeted.
[0009] A training device for strengthening the muscles in the lumbar region is known from WO 2013 / 064589 A1 and DE 10 2011 085 571 A1. This muscle group requires special attention because many people have underdeveloped muscles in this area due to frequent, prolonged sitting, which can lead to severe pain. This training device comprises a frame, a seat with a seat for free sitting without contact with the floor, at least one backrest, a fixation device for the pelvis, and a fixation device for the hands or arms. The seat with the fixation device for the pelvis is movable relative to the backrest with the fixation device for the hands and arms.
[0010] The disadvantage is that the exercise to strengthen the muscles in the lumbar region is repeatedly performed incorrectly by those using this device, which jeopardizes the success of the training. A particular problem is that muscle groups other than those in the lumbar region are used to move the seat against a certain force. Well-trained, outer muscles then compensate for the force that should actually be generated by the deeper muscles. This is achieved by the trainees, particularly by engaging other muscles through lever movements of the legs, and sometimes also the arms.
[0011] This problem has so far been solved by having experienced, trained trainers and physiotherapists supervise the exercises and repeatedly point out errors in execution. Since, despite such instruction and support, trainees repeatedly resort to incorrectly performing the exercises, regular and close supervision of trainees is essential to ensure effective training with such a training device. This results in significant time and expense.
[0012] The object of the invention is to provide a training device which makes incorrect exercise execution significantly more difficult and thus forces correct execution of the exercise for training the muscles in the lumbar region, so that the trainees perform the exercise intuitively correctly and the deeper muscles are effectively stimulated.
[0013] According to the invention, this object is achieved by a training device according to the independent claim. Advantageous embodiments of the invention are specified in the dependent claims.
[0014] The object is achieved in particular by a training device for training individual muscle groups in the upper body, which training device has a support frame and a training unit. The training unit has an upper body support element and a seat. The seat is movable on an arc-shaped path relative to the upper body support element in such a way that the pelvis, when the upper body is at rest and resting on the upper body support element, can move in a pendulum-like manner against an adjustable counterforce acting in at least one direction of movement. The seat is designed such that only the buttocks area is supported and that no elements for supporting the legs or feet are arranged on the training device. There are also no elements on the training device that rest on the legs or feet for fixing the pelvis to the seat.This means that there are no elements on the training device on which the user could support his legs during training.
[0015] During training with the training device, the pelvis performs a pendulum-like movement with the seat. According to the invention, the pelvis moves back and forth along a curved path. To ensure this, the seat is movable along a curved path. During training, the pelvis thus performs a swinging movement around a joint, specifically around one of the vertebrae in the upper body. This pendulum-like movement corresponds to the natural movement pattern in the body, in which the muscles move other body parts around a joint that acts as a pivot point. This trains the muscles surrounding the corresponding joint or vertebra.
[0016] The upper body is secured to the upper body support element. This can be achieved by the user pressing the upper body against the upper body support element. This can be supported by other elements on the training device, such as straps. The seat is preferably movable while the backrest is fixed.
[0017] The counterforce acts predominantly in one direction of movement. This means that in order to move the seat in one direction, the person exercising must exert increased force to move the seat and thus overcome this counterforce. The return movement of the seat also occurs under the influence of the counterforce. The counterforce pushes the seat back, thus supporting the return movement. During the return movement, no effort is required to overcome the counterforce, but effort is required to move the seat back slowly and in a controlled manner. The return movement corresponds to an eccentric movement of the muscles. The return movement is preferably performed as a controlled return movement using the corresponding muscles to be trained. Depending on the direction of the counterforce, different muscles are required to move the seat with the help of the upper body muscles.The direction of the counterforce can therefore determine whether the muscles being trained are those in the back, abdominal area, or lateral muscles. The counterforce to be overcome stimulates the corresponding muscles, and the intensity of the training can be adjusted depending on the set level of the counterforce.
[0018] The training device according to the invention primarily achieves a reduction in the compensation options provided by other muscles by eliminating the undesirable support options provided by the feet and, in particular, the legs. Advantageously, the trainee cannot facilitate the exercise by levering on fixing elements or support options. Therefore, the training device does not contain any elements that could serve as support elements for the legs or feet, nor any elements that are primarily intended to fix the pelvis to the seat. The training device is designed in such a way that the trainee cannot support their legs or feet on the floor or the training device.This advantageously deprives the exerciser of the opportunity to support themselves on the support elements, thus forcing correct exercise execution without compensating lever movements. The seat itself does not constitute such a support element for the legs or feet, even if the upper part of the thighs rests on it. According to the invention, the seat is designed in such a way that only the buttocks area is supported and there is no support option for the legs or feet. The buttocks area can also include the upper area of the thighs, i.e. the upper 50% of the thighs or preferably the upper 20% of the thighs or particularly preferably the upper 10% of the thighs. However, the training device does not provide any option for supporting the rest of the thighs.For the purposes of the invention, support for the legs or feet also includes any fixation or placement of the legs or feet, in particular the lower region of the legs from the middle of the thighs downwards, as well as the feet. The training device therefore has no elements that rest on the middle and lower region of the thighs, the lower legs, the knees or feet or fix them in any way. The leg and feet hang freely and the pelvis is held on the seat primarily by a certain amount of friction between the seat and the buttocks. Increased muscle engagement may be necessary for a correct seat. It is particularly preferred if the pelvis is only in contact with the seat via the ischial tuberosities (tuber ischiadicum), so that the seat can be moved by a pendulum movement of the pelvis around a vertebra in the upper body, moving the seat in an arcuate path.
[0019] The lack of leg or foot support prevents the user from using, for example, fixation elements on the lower legs to support themselves in such a way that the thigh muscles or the outer hip muscles take over the force required to move the seat, thus relieving the strain on the deeper, vertebral muscles that are actually being trained. When training with the training device according to the invention, the thigh or hip muscles cannot be used to move the pelvis and thus the seat while the upper body remains stationary. Compensation by the hip and thigh muscles is thus avoided.
[0020] Due to the lack of fixation elements on the legs for securing the pelvis, the pelvis is secured only by the seat itself. To enable the pelvis to be secured to the seat, a special design of the seat itself is required. The pelvis's fixation to the seat is primarily achieved through friction between the seat and the user.
[0021] In one possible embodiment, the seat is designed in the form of a saddle, for example, a bicycle saddle. Another variant provides for the pelvis to be secured by the user sinking into the soft surface of the seat, creating sufficient friction to fix the buttocks and thus the pelvis to the seat. Slipping is thus prevented by the weight exerted by the user. The seat is designed with a flat top surface and has no seat bolsters or other securing elements.
[0022] The seat preferably comprises a foam covered with a covering. The friction between the seat and the user is determined by the hardness of the foam and the choice of material, such as leather, synthetic leather, or fabric, for the covering. The seat surface preferably has a sufficient degree of roughness.
[0023] In a particularly preferred variant, the seat has a rectangular shape with a length in the direction of sitting. In a suitable variant, the length is less than 30 cm, 25 cm, or 20 cm. The seat is then designed only as a contact surface. It does not provide any support for the legs, nor for the upper thigh area, which creates a pressure to perform the exercises correctly. The short seat therefore reduces the opportunity to use the legs to support oneself in a lever-like manner and then to use the hip muscles to relieve the strain on the muscles in the upper body that are actually being trained. According to the invention, the length of the seat is arranged in the direction of sitting, so during training the length is parallel to the ventral and dorsal main direction of the exerciser.
[0024] Adjusting the counterforce as needed advantageously allows for training that is tailored to the individual's fitness level. The counterforce to be overcome during training is preferably adjusted by varying the incline of the entire training unit, and thus the direction of movement of the seat relative to the floor. The incline of the training unit also adjusts the incline of the seat element's direction of movement. Since the seat moves along an arc-shaped path, the incline of the track is also changed, i.e., the track is tilted. By fixing the training unit in a specific position, i.e., at a specific angle of inclination, the direction of movement of the seat element is also adjusted, which determines the angle to the horizontal.A change in the direction of movement always influences the proportion of the weight force on the seat element, which allows the training intensity of the exercise to be adjusted effectively and easily.
[0025] If the seat has to be moved further up due to the incline, the weight force, which is also caused by the exerciser themselves, has a greater influence, and the counterforce increases with a more tilted exercise unit. With a greater influence of weight force, the exerciser must exert more force to move the seat element, thus ensuring an effective workout. The exercise unit is preferably mounted so that it can be tilted around an incline axis relative to the support frame in such a way that the incline of the exercise unit relative to the floor can be varied and fixed in various positions.
[0026] In an advantageous embodiment, the training device has a manually operated or driven gear mechanism located between the training unit and the support frame. The gear mechanism serves to adjust the incline of the training unit. The gear mechanism can be designed as a worm gear mechanism, particularly as a self-locking or self-locking worm gear mechanism. In one possible variant, an additional component is arranged on the worm gear mechanism, which provides the self-locking effect.
[0027] In an advantageous variant, an inclination or tilting of the training unit around an inclination axis is realized in such a way that the direction of movement of the seat runs in a plane which is arranged perpendicular to the inclination axis of the training device.
[0028] The training unit is preferably positioned so that it can be adjusted relative to the support frame. However, in possible design variations, the counterforce can also be achieved by adding additional weights, using a rubber band, or using a cable pulley system.
[0029] In order to optimise training and to adapt to different needs, the training device is preferably designed in such a way that the distance between the seat arranged in the resting position and the upper body support element can be adjusted and fixed at different distances.
[0030] In a particularly suitable embodiment, the seat is connected to the upper body support element via a joint, which is preferably designed as a swivel joint, and the distance between the seat and the joint is variably adjustable and fixable. By adjusting the height of the joint in relation to the user's body, the exercise can be initiated in different muscle groups. The area located at the level of the joint, around which the seat moves in an arc-shaped path, is always particularly stimulated and stressed. If the joint is located at the level of a lumbar vertebra, for example, the muscles around this lumbar vertebra are particularly strengthened through training. The pelvis then performs a pendulum-like movement around the corresponding lumbar vertebra.Thus, by adjusting the height of the joint around which the seat moves in an arc-shaped path, the muscle segment to be trained can be varied and specifically stressed.
[0031] For this purpose, the seat is preferably coupled to the joint via telescopic elements. For the purposes of the invention, telescopic elements are understood to be extendable, interlocking tubular elements or elements similar to a hollow profile. Other coupling elements that can be adjusted in length are also possible. The relevant factor here is the change in the distance between the pivot joint and the seat element.
[0032] Preferably, the distance between the upper body support element and the joint can also be adjusted and fixed in different positions.
[0033] According to an advantageous embodiment, the training device has a rest or securing elements for the arms or hands. The securing elements are particularly preferably designed as handles. Alternatively, the exerciser can also hold on to the backrest. However, handles arranged in front of the backrest, i.e., those that are easily accessible for the arms and hands when the upper body is restrained, enable comfortable securing of the upper body. An alternative option for securing the upper body is straps that connect the upper body to the upper body support element.
[0034] The training device is designed such that the seat's movement follows an arcuate path. The arcuate path can be described as an nth-order polygon, i.e., any curved path. One possible embodiment is an elliptical path. Preferably, the seat's movement follows a circular path.
[0035] In a particularly suitable variant, the seat is connected to the upper body support element via a pivot joint. The curved path of the seat then results from a pendulum movement of the seat around the pivot joint. In one possible embodiment, the seat is connected to the pivot joint by means of elongated elements, allowing the seat to move around the pivot joint like a rigid pendulum. In an alternative embodiment, the training device has a curved guide on which the seat can be guided.
[0036] According to one possible embodiment, the upper body support element can be adjusted and fixed in different positions and at different distances from the seat.
[0037] The upper body support element is preferably designed as a backrest, a side rest, or a rest for the front area of the upper body. In a special variant, the upper body support element is designed as a support element for the upper torso, i.e., in particular, the shoulder and chest area. Alternatively, the upper body support element can also be designed as a rest to support the lower torso, in particular the lumbar region. The choice of the upper body area the exerciser uses for support, in conjunction with the direction of the counterforce, determines the muscle to be trained.
[0038] In a version with a backrest, the lower abdominal muscles, i.e., the external oblique abdominal muscles (musculus obliquus externus), the internal oblique abdominal muscles (musculus obliquus internus), and the rectus abdominis muscles, are stimulated and trained. The hip flexors, also known as hip benders, are advantageously not able to engage in compensatory activity.
[0039] In another embodiment, in which the upper body support element is designed as a rest for the front of the upper body, the deep back muscles, particularly the multifidus muscle, are trained. The hip extensors, also known as hip extensors, cannot compensate for this. This prevents the exerciser from simplifying the exercise by having the hip extensors relieve the strain on the deep back muscles that are actually meant to be trained. The exerciser is forced to stimulate the deep back muscles, making training of the deep back muscles significantly more effective.
[0040] In another embodiment, the upper body support element is designed as a side rest. This specifically trains the transverse abdominal muscles (musculus transversus abdominis). The hip abductors, also known as hip abductors, can advantageously not function compensatorily.
[0041] For the realization of the invention, it is also expedient to combine the above-described inventive embodiments, embodiments and features of the claims in a suitable arrangement.
[0042] The invention will be explained in more detail below using exemplary embodiments. The exemplary embodiments refer to various embodiments of a training device according to the invention and are intended to describe the invention without limiting it.
[0043] The invention is explained in more detail with the aid of drawings. Fig. 1a a training device from the front in a perspective view, Fig. 1b a rear view of the training device Fig. 1a in a perspective view, Fig. 1c a perspective view of the training device of the Figuren 1a and 1b in a perspective view from above, Fig. 2a a side view of a training device, Fig. 2b a rear view of the training device Fig. 2a , Fig. 3a a side view of a training device with a swiveled seat, Fig. 3b a side view of a training device with a height-adjustable seat, Fig. 3c a training device with a training unit inclined relative to the support frame, Fig. 3d a training device with a training unit inclined by 180 ° relative to the support frame, Fig. 4 a schematic representation of a training device with a backrest for the front area of the upper body, Fig. 5 a schematic representation of a training device with a side rest and Fig. 6 a schematic representation of a training device with a backrest.
[0044] Figur 1a shows a training device 1 with a support frame 2 and a training unit 3. The training unit 3 has an upper body support element 4 and a seat 5. The upper body support element 4 in this embodiment is designed as a backrest 4 with a curvature 4A in the lower area. Above the upper body support element 4, two fixing elements 6 for the arms or hands in the form of handles 6 are arranged. The seat 5 is designed here as a contact surface with a short length 5L in the direction of the seat. Such a narrow seat 5 only offers a support surface for the buttocks of the trainee, while the thighs are not supported. The seat 5 therefore serves here as a contact surface for the ischial tuberosities. There is no fixation option for the legs or feet, so that the power to move the seat 5 must necessarily be provided by the upper body muscles.The exerciser cannot simplify the exercise by supporting themselves with their legs and using their thigh or hip muscles for support. Seat 5 is connected to the training unit 3 via a joint 7. During training, the exerciser can move the seat 5 while the backrest 4 is stationary, causing the seat 5 to perform an arcuate movement around the joint 7. In one possible variation, the seat 5 is moved around the joint 7 in a circular path, like a pendulum.
[0045] Figur 1b shows the training device 1 with the support frame 2 and the training unit 3 in a rear view. The handles 6 are detachably attached to the backrest 4, and the seat 5 is designed as a narrow contact surface. It is crucial that only the buttocks can rest on the seat 5. There are no resting or securing elements for the thighs, lower legs, knees, or feet, as these would encourage the user to make the exercise easier by using other muscle groups, such as the thigh muscles, to move the seat 5 against a certain force.
[0046] To adjust the inclination of the training unit 3, a crank 8 is arranged on the training device 1. By means of this crank 8, the inclination of the training unit 3 relative to the support frame 2 can be set in various positions, whereby the training intensity can be adjusted. This training device 1 is shown in a perspective view obliquely from above in Fig. 1c shown.
[0047] In Fig. 2a a side view of the training device 1 is shown. The upper body support element 4 is also designed as a backrest 4 with a curve in the lower area. This curve prevents the upper body from being at a distance from the upper body support element 4 in this area during training. This type of fixation of the upper body to the upper body support element 4 ensures that the relevant deeper muscles in the upper body are trained in this area and the trainee does not simplify the exercise by incorporating other, stronger muscles into the training using lever movements, here in particular of the upper body. The seat 5 is arranged so that it can be moved on rigid connecting elements 9 and can be moved along the rigid connecting elements 9 and thus adjusted in height. This makes it possible to choose between different deep-lying muscles along the spine.The muscles primarily trained are those located at the level of joint 7, around which the seat and thus also the pelvis perform a pendulum-like movement during training. Fig. 2b A rear view of this training device 1 is shown.
[0048] In Figur 3a 1 shows a side view of the training device 1. The seat 5 is shown here in a pivoted position, with the seat 5 being connected to the joint 7 via rigid connecting elements 9. The seat 5 and the connecting elements 9 can be pivoted like a pendulum about the joint 7. The pelvis of a person sitting on the seat 5 moves like a pendulum with the seat 5 during training, so that the pelvis executes a pendulum-like movement around the corresponding vertebra of the upper body. The seat 5 and the elongated connecting elements 9 can be pivoted by up to 60° during training, while the upper body support element 4 and the handles 6 remain firmly in place.
[0049] A side view of such a training device 1 with a height-adjustable seat 5 is shown in Fig. 3b The seat 5 is arranged in a lower position than in the Figuren 3a and 1a bis 1c The distance between seat 5 and joint 7, and thus the height of seat 5, is adjustable via a spindle drive using a crank 10 for seat height adjustment. Due to the greater distance between seat 5 and joint 7, the pelvis moves pendulum-like around those vertebrae of the upper body that are located higher up. The pivot point in the upper body is thus shifted upward, so that muscles located higher up are stimulated and trained.
[0050] In Fig. 3c The training device 1 is shown with a training unit 3 inclined at 45° relative to the support frame 2. The inclination of the training unit 3 can be adjusted and fixed in various positions. This allows the intensity of the training to be varied at different levels. The trainee rests his back against the upper body support element 4, designed here as a backrest, and moves the seat 5 along a curved path, with gravity having an increased influence. The more inclined the training unit is, the greater the effort required to move the seat 5. To adjust the inclination of the training unit 3 and thus also of the upper body support element 4 and the seat 5, the training unit 3 is connected via a coupling rod 11 to a spindle gear, which can be operated via a crank for inclination adjustment 8. In Fig. 3d The training device 1 is shown with the training unit 3 at an incline of 180°. The backrest 4 is horizontal and the seat 5 is vertical.
[0051] A schematic representation of the training unit 1 is shown in a variant in which the upper body support element 4 arranged on the support frame 2 is designed as a backrest for the front area of the upper body 4. Fig. 4 shown. The trainee, shown here from the side, fixes their upper body by resting it on the upper body support element 4 and holding their hands on handles 6. The seat 5 is connected via connecting elements 9 to a joint 7, around which the rigid connecting elements 9 move the seat 5 along a curved path, here pendulum-like along the direction of the pendulum movement 12. As a result, the trainee's pelvis, positioned on the seat 5, also moves pendulum-like around a vertebra in the upper body.
[0052] A further variant with an upper body support element 4 arranged on the support frame 2 and designed as a side rest 4 is shown in Fig. 5 shown schematically. The trainee, shown here from the front, moves the pelvis arranged on the seat 5 in a lateral movement along the direction of the pendulum movement 12. The upper body is fixed by resting on the side rest 4 and by holding on to the handles 6 connected to the side rest 4. This trains the transverse and oblique abdominal muscles in particular. In this embodiment, the seat 5 is also connected to a joint 7 via rigid connecting elements 9, whereby the seat 5 can be moved on a curved path. The legs or feet of the trainee can advantageously not support themselves in such a way that the trainee incorrectly uses the usually better trained hip abductors to perform the exercise through lever movements.
[0053] In Fig. 6is a schematic representation of a training device 1 with an upper body support element 4 designed as a backrest 4, which is arranged on the support frame 2. The user moves the seat 5 with the help of his abdominal muscles on an arcuate path along the schematically indicated direction of the pendulum movement 12. The distance between the joint 7, around which the seat 5 performs the pendulum movement, and the seat 5 can preferably be adjusted by the length of the connecting elements 9. The upper body is fixed by placing the back against the upper body support element 4 and by holding the hands on the handles 6. The pelvis can thus perform a pendulum-like movement on the seat 5.
