Abstract

An exercise device (10) for muscular strengthening of the human shoulder girdle region has a bow-shaped, multi-curved base body (12) having an inner shoulder abutment portion in relation to a plane of symmetry (S) of mirror symmetry from an arcuate medial connecting portion (14) on both sides of the plane of symmetry (16) and an outer Armauflageabschnitt (18) has. The medial connecting portion is dorsally open and there are provided dorsal lateral connecting portions (20) which transition at transition portions (22, 24) into the shoulder supporting portions and the arm supporting portions and connecting them together. As seen from the side, the shoulder support portions and the arm support portions are oppositely curved so that the shoulder support portions support peaks (26) and the arm support portions form support bottoms (28) which together define a support plane (A) perpendicular to the plane of symmetry. At this time, the shoulder rest portions are weaker curved than the arm rest portions so that the transition areas between the shoulder rest portions and the lateral joint portions are farther from the support plane than the transition areas between the lateral joint portions and the arm rest portions.

Description

TECHNICAL AREA

The invention relates to a training device for muscular strengthening of the human shoulder girdle region according to the preamble of claim 1. Such training devices are not only for the prevention, but also for the rehabilitation of muscle damage. It is about the strengthening of the external rotators in the shoulder girdle area, the problem solving of muscular shoulder pain and preventive measures to prevent such problems, for which such exercise equipment in the context of physiotherapy treatments are used to a large extent.

STATE OF THE ART

The prerequisite for a healthy and powerful shoulder girdle area is balanced muscle development, muscle balance. Muscular dysbalances that affect the shoulder girdle area are understood to be increased muscle shortening in the chest area and / or muscle weakening in the back area. Affected here are the external rotators (infraspinatus and teres minor) on the rotator cuff leading to the humeral head in the socket. The result is a so-called arthromuscular imbalance, which entails an unfavorable stress distribution on the joint structures. The consequences are improper loading, premature wear on the articular cartilage, overloading of the tendons, painful muscle tension with increased risk of injury from strains and muscle fiber tears and muscular dysfunction and coordination disorders. On the one hand, muscular imbalances can reduce the load bearing capacity of the shoulder joint structure and on the other hand impair performance.

As causes for the occurrence of muscular dysbalances u. a. a lack or lack of physical stress, one-sided stress in everyday life or sports, incorrect and overstressing as well as insufficient regeneration, unfunctional movements and injuries or disorders of the musculoskeletal system. A typical example of what can result in a dysbalance in the shoulder girdle area, is the so-called round back: This is a shortened chest muscles (here must be stretched) and a weakened upper back muscles (here must be strengthened) before.

To counteract an arthromuscular imbalance, the external rotators should be specifically strengthened by means of suitable exercises for isolated muscle stimulation. The most efficient exercises for strengthening the external rotators require that the upper arm is raised laterally / cranially, so that an arm rotation about the upper arm axis can be carried out in an isolated manner. Then it is particularly important to the correct execution of the movement in order to avoid a counterproductive Mittrainieren other muscle groups, especially the Innenrotatoren. In case of advanced muscular dysfunction of the rotator cuff of the shoulder, which can lead to a narrowing in the shoulder joint, more precisely in the subacromial space of the shoulder joint (so-called impingement syndrome), however, the lateral / cranial lifting of the upper arm already causes problems, because the humerus as a result of weakening resp Underdevelopment of the external rotators is pulled from the shouldered, relatively strong deltoid muscle (deltoid) against the bony shoulder roof, which is regularly associated with stinging pain. Against this background, generic training devices are used which both support and guide the upper arm in the execution of the exercise so that the outer rotators can be trained without great pain and in isolation.

According to the preamble of claim 1 forming document DE 199 54 650 C2 a training device for muscular strengthening of the human shoulder girdle area on a bow-like, multi-cranked body, in respect to a plane of symmetry mirror symmetrical training starting from an arcuate, medial and dorsal closed connecting portion ("arc section" in the linguistic use of this document) on both sides of the plane of symmetry an inner Shoulder rest section and an outer armrest has. More specifically, in this prior art, the main body is bent such that a vertex (S) of the arc portion in the plane of symmetry (EE) and its curved axis in a first plane (E1-E1) is located, bent from the arc portion two approximately at right angles , the inner shoulder rest sections forming legs emanating from their axes in a second plane (E2-E2). The lower ends of the legs go into the approximately right-angled bent outward armrests whose outermost ends are curved upwards. The armrests themselves have three sections (A, B, C), namely inner sections (A) which adjoin the legs and, with respect to the plane of symmetry (EE), include a first angle smaller than 180 °, middle sections (B), which are angled in the direction of the first plane (E1-E1) and additionally have a second angle which is smaller than the first angle, and outer sections (C), which at an angle facing the middle sections (B) in the direction of the first plane (E1-E1) and directed away from the legs.

This training device, compared to other known exercise equipment, as z. B. in the document US 5,580,342 are characterized, inter alia, distinguished by the fact that the dorsally closed bow portion can be brought with his rear or lower arch portion approximately in the shoulder blades on / on the back of the exercising person to the plant, so that in the context of a physiotherapeutic treatment for stimulating the back muscles desired touch stimulus on the area of the skin over the shoulder blades can be generated, has been used for many years by people with different body dimensions successfully for the production of a muscular balance in the shoulder girdle area. However, the use of this training device has certain limitations in individuals with acute pain in movement and / or severely limited mobility of the shoulder (s). Because to create this training device to perform a rotational movement of the shoulder joints, in which the upper arms of dorsal / cranial, ie from behind / top are placed on the training device, which can sometimes be painful or even as a result of the greatly restricted mobility of the shoulder (s) not (anymore) possible.

TASK

The invention is based on the prior art according to the document DE 199 54 650 C2 The object of the invention to provide a training device for muscular strengthening of the human shoulder girdle area, which can be used in a targeted manner to strengthen the external rotators to counteract a muscular dysbalance on the shoulder joint, even if in the exercising person, the mobility in the region of the shoulder joint is more limited ,

PRESENTATION OF THE INVENTION

This object is achieved by the features specified in claim 1. Advantageous or expedient developments of the invention are the subject of claims 2 to 15.

In an exercise apparatus for muscular strengthening of the human shoulder girdle region having a bow-shaped, multi-curved body having an inner shoulder rest portion and an outer arm rest portion in a mirror-symmetrical plane forming symmetry plane from an arcuate medial joint portion on both sides of the symmetry plane, according to the present invention medial connecting portion dorsal open and there are dorsal lying, lateral connecting portions provided at transition areas in the shoulder support portions and Armauflageabschnitte and connect them together, wherein seen in a side view of the base seen the Schulterauflageabschnitte and the Armauflageabschnitte are oppositely curved, so that the Schulterauflageabschnitte respectively an edition high point and the Armauflageabschnitte each form a support low point, which together a defining the support plane perpendicular to the plane of symmetry, and wherein the shoulder support portions are less curved than the arm support portions such that the transition regions between the shoulder support portions and the lateral connection portions are farther from the support plane than the transition regions between the lateral connection portions and the arm support portions.

Due to the fact that according to the invention the medial connecting portion of the training device is dorsally open, the training device can initially be comfortably applied from the front, without it - as in the generic state of the art - to be passed over the head, including at least one arm if necessary To raise the pain would be high. In addition, since the lateral connecting portions are formed dorsally lying, can - be placed on the Armauflageabschnitte - v. Cranial, ventral / cranial, ie from the front / top of the Armauflageabschnitte - contrary to the generic state of the art - without problems. H. the upper arms do not need to be rotated "behind" the shoulder joint.

Furthermore, the dorsal position of the lateral connecting sections causes them - again unlike in the generic state of the art - can no longer be supported on the chest. The training device according to the invention can therefore be used by people with a pacemaker easily.

Further, because according to the invention the shoulder support sections on the one hand and the arm support sections on the other hand have an opposite curvature, so that the shoulder support sections each form a support high point and the arm support sections each form a support low point, which together define a support plane perpendicular to the plane of symmetry, the training device can hang up the upper arms on the Armauflageabschnitte under the action of gravity readily, ie automatically align the body of the exercising person. This may lead to a slippage of the training device over the shoulders in a (use) position in which the upper arms are (substantially) in the predetermined or device immanent support plane. In other words, come it leads to forced guidance of the training device into a correct training position; the exerciser can not occupy any arbitrary position on the exercising person's body, which precludes application errors. In this respect, the training device is virtually self-explanatory and also allows independent training, without the need for an external guide to the correct positioning of the training device on the body, which simplifies the use.

Further, since the shoulder rest portions are weaker curved than the arm rest portions, so that the transition areas between the shoulder rest portions and the lateral joint portions are further away from the support plane than the transition areas between the lateral joint portions and the arm rest portions, the above-described self-alignment of the exercise equipment on the body becomes troublesome prevents even preventive support of the training device on the back. The lateral connecting sections are therefore behind the shoulder blades and come during training at any time on the shoulder blades to the plant. The training device as a whole touches the body of the exercising person so only on the shoulders and under the upper arms, otherwise it runs freely from the body or spaced.

In sum, the training device can be used in a proven manner targeted to strengthen the external rotators to compensate for a muscular dysbalance on the shoulder joint, but compared to the above-described prior art, but easier to create and use correctly, especially of people in the field of the shoulder joint are very immovable.

In order to favor the self-alignment of the exerciser even before placing the upper arms, the exerciser may be configured to have a center of mass that is substantially on a line of intersection between the plane of symmetry and the support plane. An advance direction of the training device thus takes place already when placing the training device with his shoulder rest sections on the shoulders of the exercising person.

In principle, it is conceivable that the training device is formed according to the prior art with a multi-cranked body. In particular, with regard to a comfortable fit of the base body, however, is preferably formed continuously curved. As a result, excessively stiff (bent) and resilient (straight) areas of the body are avoided, so that there is a homogeneous spring behavior of the body. In this case, the curvatures of the arm and shoulder rest sections can be designed so that the training device in use in a person with average stature "cling" to the body, thus the respective arm or shoulder rest area is increased and the pressure is distributed more evenly. The wearing comfort is additionally increased if in a preferred embodiment of the training device, a substantially rigid core of the body is surrounded by an elastic sheath.

In principle it is possible, the core of the body of a hollow body, for. B. to form a tube. However, in view of a simple production, it is preferred if the core is formed from a solid material whose cross-section does not deform excessively when bending the base body and which may be present as a rod material, for example. In this case, the core can have a circular cross-section with a substantially constant diameter in a particularly cost-effective embodiment. It is also conceivable, however, that the cross section of the core varies as seen locally in accordance with locally required strength / stiffness or to increase the contact surface seen on the body over the length of the body, for example, locally oval designed.

Finally, end caps can be plugged onto the free ends of Armauflageabschnitte, which protects the case of an embodiment of the training device with elastic wrapping the latter from damage and at the same time serves to cover any cut edges of the rigid core, which would have to be elaborately deburred without cover to avoid injury.

Further features, properties and advantages of the training device according to the invention will become apparent to those skilled in the art from the remaining claims and the following description of a preferred embodiment.

DETAILED DESCRIPTION OF THE EMBODIMENT

In the figures, a training device for muscular strengthening of the human shoulder girdle area with 10 quantified. The training device 10 has a bow-shaped, multiply curved body 12 , which in relation to a plane of symmetry S (see the 7 . 8th and 10 ) mirror-symmetrical training starting from an arcuate, medial connecting portion 14 on both sides of the plane of symmetry S, an inner shoulder support section 16 and an outer armrest portion 18 has.

According to the particular 1 and 4 is the medial connection section 14 dorsally open. Furthermore, there are dorsal lateral connection sections 20 provided at transition areas 22 . 24 in the shoulder rest sections 16 and the armrest sections 18 go over and connect them together. Here are in a side view (see 3 and 9 ) of the main body 12 seen the shoulder rest sections 16 and the armrest sections 18 curved opposite, namely the shoulder rest sections 16 cranially curved while the Armauflageabschnitte 18 curved caudal. Thus, as best in the 3 . 9 and 10 you can see the shoulder pad sections 16 each a circulation high point 26 and the armrest sections 18 in each case a circulation low point 28 , which together define a bearing plane A extending perpendicular to the plane of symmetry S. Here are the shoulder rest sections 16 less curved than the Armauflageabschnitte 18 so the transition areas 22 between the shoulder rest sections 16 and the lateral connecting portions 20 dorsally further away from the support plane A than the transition areas 24 between the lateral connecting sections 20 and the armrest sections 18 (see again the 3 and 9 ).

As the figures show in general is the main body 12 of the training device 10 essentially continuously curved, has - unlike the above-described prior art - so neither longer straight sections nor offsets, ie mutually angled bent areas. According to the particular 1 . 2 . 7 . 9 and 10 ends the armrest sections 18 of the basic body 12 lateral with free ends 30 that over the circulation lows 28 protrude ventrally and cranially and are thereby possibly tilted medial with respect to the plane of symmetry S, as in 7 shown. at 32 are on the free ends 30 the armrest sections 18 essentially cup-shaped end caps made of, for example polyvinyl chloride (PVC) attached and fastened there suitably, z. B. by means of a hot or hot melt adhesive.

How to continue from the 10 and 11 shows, the body indicates 12 in the illustrated embodiment, a substantially rigid core 34 on, that of an elastic or yielding envelope 36 is surrounded. More specifically, here is the core 34 molded from a solid material, which may be, for example, a thermoplastic such as PVC. The the core 34 in the embodiment shown on the entire length padding enclosing enclosure 36 here consists of a foamed tube material such. B. one Elastomer based on acrylonitrile-butadiene-styrene rubber (NBR).

In the embodiment illustrated in the figures, furthermore, the mass distribution with respect to the support and symmetry planes A, S is made such that the training device 10 has a center of mass that is essentially on a section line L (see 10 ) lies between the plane of symmetry S and the support plane A.

With regard to the examinations made by the inventor preferred dimensions of the training device 10 is with reference to the 7 to 11 To state the following: The core 34 of the basic body 12 As shown, it may have a circular cross section with one over the length of the main body 12 essentially constant diameter D (see 11 ), which are in a range of 25 to 40 mm, e.g. B. should be about 30 mm. The the core 34 surrounding cladding 36 of the basic body 12 should a wall thickness W (cf. 11 ) of 8 to 15 mm, for example about 12 mm. The total width B (see 8th ) of the main body 12 can be measured perpendicular to the plane of symmetry S measured in a range of 700 to 800 mm, z. B. 760 mm ("projected" measure).

Out 7 also shows that the free ends 30 the armrest sections 18 in the front view of the exerciser 10 seen with an imaginary, parallel to the plane of symmetry S plane E include an acute angle α, which should be in a range of + 30 ° to -30 °, preferably in a range of 0 ° to -15 ° and in the illustrated embodiment approx. 11 °. This value has been found in experiments to be particularly advantageous because the free ends 30 the upper arm well in the arm rest sections 18 lead and at the same time allow unhindered Vorbeischwenken the forearms.

As continues in 9 is indicated in the side view of the training device 10 seen a clear distance H between the support high points 26 the shoulder rest sections 16 and the circulation lows 28 the armrest sections 18 between 135 and 215 mm, for example 175 mm ("projected" dimension). Furthermore, in the side view of the training device 10 from 9 to see that the shoulder rest sections 16 in or near the pad high point 26 a radius of curvature RS and the armrest portions 18 in or near the pad low point 28 have a radius of curvature RA ("projected" dimensions). A ratio RS / RA of the radius of curvature RS of the shoulder rest sections 16 to the radius of curvature RA of the armrest portions 18 should be between 2 and 6. In the illustrated embodiment, this ratio is RS / RA, for example, about 4.1. In absolute terms, the radius of curvature RS of the shoulder rest sections 16 in a range of 130 to 170 mm, z. B. about 150 mm, while the radius of curvature RA Armauflageabschnitte 18 in a range of 30 to 50 mm, for example, may be about 37 mm ("projected" dimensions).

How finally the top view of the training device 10 according to 10 should be taken, should be a clear distance G between the shoulder rest sections 16 in the support plane A measured in a range of 100 to 200 mm, z. B. about 140 mm, so that the shoulder rest sections 16 in a muscular area of the shoulder to rest without squeezing vessels in the neck area.

To create the training device 10 this is done in front of the chest of the exercising person with both hands on the medial connecting section 14 or the shoulder rest sections 16 held, horizontally aligned and then around the medial connecting portion 14 twisted that the free ends 30 show caudal / ventral. The training device 10 is now moved in dorsal direction until the medial connecting section 14 located just in front of the neck of the exercising person. Starting from this position becomes the training device 10 again around the medial connecting section 14 pivots until the shoulder rest sections 16 on the shoulders of the exercising person come to rest, with the training device 10 after removing the hands according to the in 3 shown position automatically (before) aligns. In the last step, the upper arms are first lifted ventral / cranial in a rotational movement from a medial / caudal position and then swung out laterally, and finally from ventral / cranial on the armrest sections 18 as shown in 1 to be placed. Now this is the training device 10 created correctly.

In this position of the training device 10 in which the upper arms of the exercising person in the armrest sections 18 rest, the in 3 with the movement arrow indicated twisting movement of the arms with respect to the axis of rotation R (see 1 . 2 and 4 ) alternating up and down to strengthen the external rotators of the shoulder girdle area. Basically, this rotational movement of the arms can be performed without additional resistance alone against / with gravity. To increase the resistance in the execution of the exercises can - in addition to those in the 2 to 4 shown dumbbells K - also elastic bands (eg Terrabänder), cables or barbells are used, which was only very limited, if at all possible in this diversity with the previously known exercise equipment for ergonomic reasons.

The removal of the training device 10 takes place at the end of the training in order to create the reverse order and prepares due to the ergonomic design of the training device 10 even with "tired" muscles no difficulties.

The training device 10 is used by people with different body dimensions and allows in a short time and with a high success rate a therapy for the production of a muscular balance in the shoulder girdle area. By "decommissioning" or relieving the deltoid muscle and the internal rotators, the two external rotators can be effectively isolated and thus specifically loaded for direct growth stimulation. In addition, the humeral head in the joint socket is centered precisely and centrally guided by the straight joint guide during movement. In addition, the chest muscles are constantly stretched during the exercises, while the trunk is erected as a result of the supported posture. The training device 10 thus allows a targeted correction of joint malpositions, which is promoted by the gentle movement and the dissolution and metabolism of deposits on the joint.

A regular training has positive effects on the performance in everyday life and in all kinds of sports such as all kinds of weight training, all throwing, tennis, squash, golf, swimming, etc. The exercises are self-sufficient and injuries due to the isolated muscle stimulation with very low Loads practically excluded.

An exercise apparatus for muscular strengthening of the human shoulder girdle region has a bow-shaped, multi-curved body having an inner shoulder rest portion and an outer arm rest portion in a mirror-symmetrical plane of symmetry from an arc-shaped medial connecting portion on both sides of the symmetry plane. The medial connecting portion is dorsally open and there are provided dorsal lying, lateral connecting portions which merge at transition areas in the shoulder rest portions and the Armauflageabschnitte and connect them together. As seen from the side, the shoulder rest portions and the arm rest portions are oppositely curved so that the shoulder rest portions support high points and the arm rest portions form overlay bottoms which together define a support plane perpendicular to the plane of symmetry. At this time, the shoulder rest portions are weaker curved than the arm rest portions so that the transition areas between the shoulder rest portions and the lateral joint portions are farther from the support plane than the transition areas between the lateral joint portions and the arm rest portions.
