Description

Description

The present invention relates to a device for training muscle groups, preferably in the back area.

Training devices for the muscles or for the back area are described in the literature in a wide variety of forms. For example, a training device for improving the function of the spinal muscles is known, with which the test subject can train muscle strength by performing more or less defined movements against adjustable resistance. To increase the training effect, an unstable base is used, which causes the test subject to train his sense of balance and his balance functions in parallel with muscle training. This quite complicated combination of training the back muscles with the simultaneous improvement of coordination and the metabolic situation of the affected tissues, the muscles, the intervertebral discs, the tendons and ligament structures is realized in the context of so-called horse riding therapy forms. This solution is implemented by the training device having drive means with which the seat can be set in multi-dimensional, impulse-like movements. These movements trigger a lateral flexion of the spine through different loads on the sitting bones of the person supported by the seat and also cause a change in the tilt position of the pelvis, so that the stability and function of the spinal muscles improve. The lateral flexion of the spine through alternating right-left loads on the sitting bones of the person supported by the seat is triggered when the seat support is held so that it can tilt sideways around its longitudinal axis.

The extremely complex training system described above is primarily effective in training coordination and the sense of balance, but has hardly any measurable effects in relieving chronic back pain.

Another well-known back muscle training device consists of 2 handles and 2 equal-length, tear-resistant ropes with eyelets (one for each hand). The two ropes are always placed around a bar on the wall bars about 10 cm to 20 cm above body height and then connected to form a loop using a safety knot. The test subject takes the handles, climbs onto the lowest bar on the wall bars and leans back with arms and legs stretched out. The body now slowly slides into the lower position, with arms and legs remaining stretched out. From this hanging position, the body is then stretched into the upper position. In a flowing movement, the arms are bent shortly after the body is stretched out. By breathing deeply in the lowest position and breathing out forcefully while pulling up, the respiratory system is built up and strengthened.

The solution described above does have a certain training effect on all muscles involved due to the necessary strong physical movement. However, as the inventor himself describes, the primary aim is to train the respiratory muscles.

Solutions for targeted back training to reduce or eliminate chronic back pain are not apparent here either.

The object of the invention is to create a back training device which, for example, in the case of chronic back pain caused by a reduction in muscle mass in the lumbar region (protective posture), leads to pain relief through targeted back training through muscle growth.

According to the invention, the object is achieved in that the training device has a chair or bench-like structure with a movable backrest, whereby the patient to be trained is placed with his buttocks and thighs on the seat cushion, supports his back (cat's back) against the back cushion, while his pelvis is fixed to the seat cushion by means of a conventionally applied pelvic belt attached to the base frame.

In an advantageous variant of the solution according to the invention, the movable backrest with the back cushion fixed to it is moved against the resistance of the rubber elements by a backward movement of the torso under tension of the so-called back extensors and a subsequent, passive, relaxing forward movement during the training process in order to achieve the desired effect.

Further variants according to the invention can be found in the subclaims.

In the case of chronic back pain in the lumbar region, a protective posture leads to a reduction in muscle mass, especially in the long back extensors. This weakening of the statically important muscles worsens the problem; the painful muscle tension increases further. The back trainer according to the invention provides a remedy here, with which the muscles of the lumbar spine are gently strengthened. A belt for securing the pelvis facilitates the training, which consists of a backward movement of the torso while tensing the back extensors, followed by a passive, relaxing forward movement.

After shipping, the back trainer is assembled and ready for use in just a few steps. Training for 5 minutes 3 times a week is enough to permanently eliminate back pain. The back trainer is preferably made of light gray powder-coated steel tube with dark red upholstery.

Elastic rubber elements of different strengths serve as resistance that increases with the range of motion, which is particularly important for this type of training. The rubber elements can be selected individually depending on the patient, muscle strength and training status.

Some embodiments of the present invention are shown in the drawings.

Fig. 1 shows the system in side view with the patient, who is secured to the seat cushion (4) and back cushion (1) using a lap belt (10), whereby the back cushion (1) is firmly connected to the backrest (2). The backrest (2) is connected to the base frame (3) using the round rod (5), whereby the long round rod (5) serves as the axis of rotation. The rubber elements (8) required for the working tension are held using the short round rods (6, 7) and enable the working movement. The base frame (3) ends in the floor skids (9).

Fig. 2 shows the system in the front view with back cushion (1), backrest (2), the seat cushion (4) fixed to the base frame (3) and the rubber elements (8) which are attached to the short round rods (6,7).
