Description

The The invention relates to a sports and fitness equipment for training and general Strengthening the Musculature, in particular the muscles of the arms, the shoulder girdle, the back, of the trunk and the abdominal muscles, according to claim 1.

Sports- and fitness equipment of the type mentioned are used in various training facilities, such as fitness centers, sports halls, at school sports or even in company sports facilities or the like used. You can also find them in the medical Area, z. B. in practices of physiotherapists and in aftercare facilities like health resorts or rehabilitation centers. They are increasingly being found but also in the private sector, to compensate for one-sided burdens by sitting activity or determined, constantly repetitive activities to create machines or simply certain muscle groups for the Exercise area of recreational sports. By predominantly sedentary activities it comes to a weakening and Degeneration in particular of the muscles in the lower area of the lumbar spine, to premature signs of wear on the intervertebral discs and vertebral bodies in this area of the spine. A targeted and gentle balance and endurance training this Muscle areas therefore appear advantageous. Especially advantageous appears that the sports and fitness device according to the invention not only for the application in fitness centers, sports halls and for the medical field, z. B. for rehabilitation in health resorts and in practices of physiotherapists but especially advantageous for the private and domestic sector suitable. As is known, There is a desire for physical activity in many people of leisure, due to age or - possibly imaginary - physical Shortcomings, But there are inhibitions to visit fitness centers and sports halls and to train in the presence of others.

STATE OF THE ART

fitness center and sports halls are mostly spatial very generously dimensioned and are often visited by many sports people. Therefore, one often finds here a multitude of different sporting and fitness equipment, then to very specific exercises and training sessions can be used. The practitioner then has the opportunity certain exercise weights or burdens on his needs to adjust. Since usually a larger number of sports driving visited such a fitness facility, there is a constant change of people at the mentioned exercise facilities instead of. This can cause that in front of some devices Queuing and therefore also on impatient contemporaries meets. This can lead to negative experiences that dampen the desire for self-activity.

Generally well-known are the so-called "sit-ups", to which one is with the back laying flat on the floor, bringing the bent arms over his shoulders and hands crossed behind the head. From this position, you can now focus on sitting position and then go back to the starting position. A second person can Alternatively, keep the outstretched legs on the ground. A disadvantage of this exercise is that you have the back muscles jerkily must strongly tighten to the resting mass of the upper body in To bring movement. Although this exercise is certainly the abdominal and back muscles trains and strengthens, Can it cause unwanted overloads and strains and up to a painful herniated disc to lead. Especially for untrained people is this exercise therefore as an introduction to a physical activity rather a hindrance.

Out Television and advertising is a simple "belly roller" consisting of one on one axis rotationsbeweglich fastened wheel and with one each Handle on each side of the axle. By moving back and forth This scooter, kneeling on the ground, can be stretched and bent of the back and the arms exercises make the hull and back work out. The disadvantage of this certainly very easy to manufacture device is that it is not stable and therefore there is a risk, the fingers on To pinch the ground and injure yourself. There is no one else Stop to which a maximum extension would be braked. Exercises with this device have to at the beginning of a movement jerky, creating the danger of strains. Ultimately, the roles on the claimed floor or carpet this underlay over Fee.

Out US 5,921,901 is a sports and fitness equipment is known, which has a base member with a horizontally movable carriage located thereon. This allows a modest amount of training of the abdominal and trunk muscles. On the base element, a vertically erectable lying surface is fixed, which can be adjusted with chocks in different steeply erected positions. By erecting the upper body, so-called "sit-ups" can be performed.On the unfixed side of the lying surface is a handle element, where you can hold on with your hands to train by lifting the stretched legs, the muscles in the lower back and The support for the back is here in the form of a straight hard surface and as an "inclined plane", which on the anatomical conditions of the back no return view takes. Again, there is the disadvantage that you have to initiate a planned exercise jerky to overcome the inertia of the mass and bring the upper body in motion.

TASK

Consequently So the task is to create a sports and fitness equipment, that is for training and general strengthening of the muscles, in particular Musculature of the arms, the shoulder girdle, the trunk and the Abdominal muscles are used. It should therefore be such that it is versatile, even for the untrained and inexperienced a gentle entry into endurance training allowed to in the free time a balance to one - sided physical stress in the Create a job. The wished Device should for use in fitness centers and sports halls as well as for use in rehabilitation, ie in health resorts and practices of physiotherapists. So it has to be sufficient be stable to intensive use at continuous load to resist. In particular, it should be for individual use in the private sector as well as for the domestic training program from professional athletes. It should also be lightweight and compact be enough for the activity personal trainer to be used at changing locations. For this If necessary, it must be dismantled into easily transportable units which, however, by no means limits the usability and stability may. The latter also applies to one compact storage option in the domestic Space to accommodate it to save space, if it once for a long time not to be used. Ultimately, it must come from the material selection be such that it is stable in everyday use and inexpensive to produce is not only to address a wide range of interested parties but they also, responsive to their interests, serve can, so, quite simply, a sporty balance to one-sided to create a professional burden. Last but not least, the material selection For the production done so that a problem-free disposal on End of life and usability is possible.

WAYS TO SOLVE THE TASK

The Invention will now be explained in more detail with reference to drawings. These drawings are exemplary; they should set out the idea of the invention, but do not restrict it or even finish it. Especially The drawings should not specify any dimensioning. The individual components of the sports and fitness device according to the invention were provided with reference numerals. In the following text will be on the according to the invention sports and fitness equipment exercising Person referred to as "the practitioner"; Distinction in male and / or female persons are not. It is noted as a precaution, that this name is absolutely gender neutral and can be seen in no way represents a rating.

In 1 the sports and fitness device according to the invention ( 1 ) shown in side view. It consists of a base element ( 2 ) which at its respective ends in each case a transverse to its longitudinal axis fixed stabilizing element ( 3 ), which causes the device is secured against lateral tilting. The ends of the two stabilizing elements are as anti-slip and to protect the substrate, each with a foot ( 4 ), which advantageously consists of a permanently elastic material. The basic element ( 2 ) consists essentially of a tubular body made of metal and is preferably at least partially arcuate and formed in side view as a circle segment. In order to achieve the greatest possible flexural rigidity, it is square, rectangular, oval or circular in cross section. The cross section may also have the shape of a rectangle whose short sides are each convexly curved outward. Such molded structural means are commercially available. In the front lower area of the base element ( 2 ), away from the position of the seat mount, is a footrest ( 5 ), whose inclination is radially adjustable. This footrest ( 5 ) can be bent, for example, from a piece of pipe and, as in 2 represented, approximately in the form of a rectangle. In the upper and / or lower area, the footrest ( 5 ) at least partially enveloped with a flexible but abrasion resistant padding material. Preferably, when using the sports and fitness device according to the invention, the feet are placed in the lower area of the footrest and held firmly with the toes or the forefoot on the upper area of the footrest. The wrapping then protects against possible pressure points when using the device without shoes. In the rear area of the base element ( 2 ) is a seat holder ( 12 ), with a vertically adjustable seat ( 13 ). Below the seat, approximately in the middle, this seat mount carries a pivot bearing ( 9 ) in which the bracket element ( 8th ) is fixed in rotation. In this pivot bearing, the bracket element ( 8th ) from both sides, so both (in the direction of the footrest) from the left or right are used. The bracket element ( 8th ) is in the transversely oriented to the main axis of the sports and fitness equipment according to the invention, horizontal portion, at least partially with a flexible but abrasion-resistant padding material ( 11 ) wrapped. As shown in detail CC, the approximately perpendicular part of the bracket element ( 8th ) at the level of the line CC and län from two sections be made adjustable in order to allow optimal adaptation to the size of a practitioner. The upper section of the bracket element ( 8th'' ) is then carried out, for example, from a tube material, the outer diameter of the inner diameter of the lower portion ( 8th' ) corresponds. The fixation of the two sections can then via a lockable by a screw clamping element ( 10 ) happen, whose function is basically known. In the rear area of the seat mount ( 12 ) is on its front, the practicing side convexly formed, backrest ( 14 ) appropriate. Preferably, this backrest ( 14 ) via an adjusting element ( 15 ) are pivoted radially in their inclination angle and fixed in a desired position. In about the front, the footrest facing third of the base element ( 2 ), at least one retaining element ( 7 ) to which the lower bracket ( 7a ) of the spring element ( 6 ) can be releasably attached. Preferably, in this area, on the two opposite sides of the base element ( 2 ), one holding element each ( 7 ) is attached to the spring element ( 6 ) to mount accordingly, when the bracket element ( 8th ) was mounted in the appropriate positioning. On the bracket element ( 8th ) is the counter-holding element ( 7 ' ), with which the upper bracket ( 7b ) of the spring element ( 6 ) is releasably connected. Since the spring element ( 6 ) with the main axis of the base element ( 2 ) forms an acute angle in plan view, the two holding elements ( 7 ) on the base element ( 2 ) fixed at a right angle to the longitudinal axis of the spring element ( 6 ) stand. The fixation of the spring element ( 6 ) on the two brackets ( 7a ) and ( 7b ) must be sure but radially movable. The spring element ( 6 ) may consist of at least one helical spring or of a combination of several replaceable helical springs, which are preferably coated with a plastic sheath in order to exclude a potential risk of injury. The coil springs are hung in perforated discs, each with the lower bracket ( 7a ) and the upper bracket ( 7b ) are connected. Particularly advantageous, however, is the use of a commercially available shock absorber with an adjustable over a wide suspension range hardness. To the sports and fitness device according to the invention ( 1 ) to make it easier to transport, can be provided, the base element ( 2 ), for example, in the amount of the line (AA) in two sections separable perform. For this purpose, one of the two subsections ( 2 ' ) and ( 2 '' ) of the base element ( 2 ), as shown in detail AA, with a connecting element ( 2 '' ), which is then firmly connected to one of the two sections advantageous. After the mating of the two sections, the connection is then determined in a suitable manner by at least one screw or by inserting at least one secured bolt. The footrest ( 5 ) must be adjustable not only in their inclination but also in their distance from the seat ( 13 ) can be optimally adjusted to the size of a practitioner. The inclination of the footrest ( 5 ) can be done in a known manner, for example. By a fixable by means of a screw clamp. For a possible length adjustment you can use the base element ( 2 ), for example, approximately at the level of the line (BB) and here a section ( 2 '''' ), the outer dimensions of which are exactly the same as the inner dimensions of the base element ( 2 ) corresponds. Over a certain distances, both parts can now, for example, be provided with at least two holes which correspond exactly to one another and which are located on the upper side of the base element (FIG. 2 ) follow one another along the longitudinal axis at a defined distance, by which the two parts can then be fixed in a desired position, for. B. by screwing or by inserting a suitable bolt. The position of the footrest ( 5 ) is then fixed with respect to the position of the stabilizing element ( 3 ), the length adjustment then takes place solely via the positioning of the two sections of the base element ( 8th ). In another embodiment, as in 2 has been illustrated, the footrest ( 5 ) is longitudinally displaceable and can be disposed on the base member, which is then made non-variable in length in this embodiment, in different positions thereon. This can be done via a catch or made steplessly adjustable. Corresponding embodiments for such length adjustability are familiar to the person skilled in the relevant art.

To use the sports and fitness device according to the invention ( 1 ), in particular, in order to be able to sit on the device more easily, it is advantageous in 1 illustrated locking element ( 16 ) to use. It has the shape of a circle segment and is equipped with corresponding retaining elements on the seat support ( 12 ) fixed at a predetermined distance such that the distance is slightly greater than the lateral projection of the seat ( 13 ). The locking element ( 16 ) has at least two radially arranged bores ( 17 ), each having a defined distance from each other. Fits to the holes of the locking element ( 16 ) is on the bracket element ( 8th ) a locking means ( 18 ), which, for example, as a perpendicular to the surface of the locking element ( 16 ) longitudinally mounted pin ( 18 ), which by spring force in one of the holes ( 17 ) can be indented. To the bending stiffness of the bracket element ( 8th ), can in the lower vertical area of the bracket element ( 8th ) a stabilizing element ( 19 ), which essentially parallel to the main axis of the base element ( 2 ver running. Since the bracket element interchangeable and from the opposite sides in the pivot bearing ( 9 ), must of course be on each side of the seat bracket ( 12 ) such a locking element ( 16 ), if this embodiment is favored. Basically, the locking element ( 16 ) in an appropriate form also on the spring element ( 6 ) opposite side of the bracket element ( 8th ) and via a correspondingly long pin in a matching hole in the wall of the seat element ( 12 ) are locked. In this embodiment, only a corresponding bore is to be attached to the opposite side of the seat support.

2 shows the sports and fitness device according to the invention ( 1 ) in a perspective view, 3 in a top view. On the reproduction of the embodiment with the locking element ( 16 ) was waived.

The human spine is not in the middle of the body along the longitudinal axis but offset laterally to the back. It has the shape of an "S" and is concave in the area of the lumbar spine, so it was particularly advantageous to use the back support ( 14 ), to which the back is leaned during the exercises, to give an appropriate shape. The back support ( 14 Although in its inclination is tilted and fixable radially, it should therefore not follow in the preferred embodiment of the body movement in the exercises. However, it is also possible to choose an embodiment in which the back support follows resiliently over a smaller range of body movement.

USE OF THE INVENTIVE OBJECT

The sports and fitness device according to the invention is used for training and general strengthening of the muscles, in particular the muscles of the arms, the shoulder girdle, the trunk and the abdominal muscles. It advantageously allows for several exercise sections, which will be described below by way of example. The footrest is adjusted so that you can take his sitting position with slightly bent knees, with the heels in the lower part of the footrest ( 5 ) and the toes, respectively. brings the front foot area under the transverse upper area of the footrest. You raise your arms, fold your hands behind your head and slowly lean your upper body back against the bend of the backrest ( 14 ), which corresponds essentially to the concave curvature of the back in the area of the lumbar spine and thoracic spine, and in which then a relaxation, vortex for vertebrae takes place. From this stretch you slowly return to the previous sitting position and repeat this exercise several times. With increasing practice success you can the backrest ( 14 ) to the horizontal. It is also possible, the spring element ( 6 ) from the bracket element ( 8th ), the latter horizontally on the base element ( 2 ), feet with bent legs in the area of the padded grip zone ( 11 ) and repeat the exercise described above from this sitting position. These exercises train and strengthen the muscles of the lower back, trunk and abdomen.

For another exercise you bring the bracket element ( 8th ) in position such that the horizontal and padded region of the stirrup element running transversely to the main axis runs approximately in the middle of the shoulder blades of a practicing person when seated on the seat and leaning back. From a bent sitting position you stretch now the body slowly with raised arms and behind the head clasped hands as far as it is possible in the direction of the backrest ( 14 ) and thus tries the return force of the spring element ( 6 ) to overcome. The upper body is now slowly bent back into the starting position, while maintaining the body tension against the return force of the spring element. This exercise is repeated several times. It trains and strengthens in particular the muscles in the area of the lumbar spine. The feet are also positioned here as described above. If the embodiment described in section [0010] with a locking possibility of the bracket element ( 8th ) is used, this bracket element can be locked in a defined position in which the spring element ( 6 ) and the stirrup element ( 8th ) to the backrest ( 14 ) is inclined. This makes it easier to take place on the sports and fitness equipment according to the invention. One then leans against the padded area of the stirrup element and then releases the detent. How a locking means must be designed to remain in an unlocked position is generally known to those skilled in the art.

In order to train and strengthen the arm muscles, especially in the area of the biceps and triceps, one sits down on the sports and fitness device according to the invention, as described in the previous exercises. You now access the bracket element ( 8th ) with both hands and outstretched arms in the padded area and leans with his back against the backrest ( 14 ) at. Now you pull the bracket element ( 8th ) against the return force of the spring element with maximum bending of the arms as far as possible approach to the chest and leads them against the return force of Fe derelements slowly back to the starting position. According to the achieved training progress, you can thereby the backrest ( 14 ) to the horizontal.

The restoring force the spring element, which, as described above, from a with conventional shock absorber adjustable spring action can be set to one Range between 10 N and 400 N, preferably between 25 N and 200 N, which is a dumbbell weight between about 1 kg and 41 kg, preferred between about 2.5 kg and 20 kg in a conventional dumbbell workout would. The information is commercially rounded. Is the spring element of at least one coil spring or a bunch several coil springs, as known from an expander, is a stepless adjustment naturally not possible. You then work with a spring element, which then consists of several individual elements, with gradual return force in several steps. As already stated is in the illustrated exercises advantageous that one with slow movements against the return force a spring element works and no jerky use of force to overcome a resistance needed. Especially The advantage here is the use of a shock absorber with infinitely adjustable restoring force because such a shock absorber the Pull-out and return force slows down at the same time and does not jerk back when unloading. With appropriate setting can also be achieved that force must be expended to the spring element to its original position due. Especially is therefore advantageous in the sports and fitness device according to the invention, that An accelerating (concentric) muscle power is also trained like the braking (eccentric) muscle power. Thus one reaches in shorter Time a much better workout of the muscles or over a defined, same period of time a more effective strengthening.
