DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention concerns a training device, especially for strengthening the muscles of the back, with a stepboard-like reclining and sitting device and a weight-guiding tension device.
DESCRIPTION OF THE PRIOR ART
Stepboards for strength training are familiar. As compared to the previously used horizontal layout boards, which resulted in great hyperlordosis when training with heavy loads or high numbers of repetitions in the power endurance range, this can be avoided with the use of stepboards. Studies have shown that the stepboard is well suited as a training device to strengthen the muscles of the arm and shoulder region while mostly avoiding strain on the spinal cord. At the same time, in addition to the dynamic loading of the upper limbs, a strong isometric tensioning of the back musculature can also be demonstrated. Consequently, the back musculature can be exercised on the familiar stepboards while largely sparing the lumbar and thoracic spinal column.
Weight-guiding tension devices are known and are used for all types of strength training. However, a disadvantage with the state of the art is that the stepboard-like reclining and sitting device and the weight-guiding tension device are each known only as individual devices. But in medical training therapy it is often necessary to combine the actions and benefits of different training devices for optimal treatment. According to the state of the art, this is only possible by placing the training devices next to each other. Because of their weight, especially that of the weight-guiding tension device, this involves a large expenditure of time and effort.
SUMMARY OF THE INVENTION
The purpose of the invention is to provide a training device, especially one for strengthening the back musculature, which has the most compact possible structure and can be operated without additional expenditure of effort.
The features of the main claim serve to accomplish this purpose.
Advantageous embodiments are described in the subsidiary claims.
The training device according to the invention, thanks to the combination of a reclining and sitting device and a pulling device to form a unified device, ensures that continual transporting of the reclining and sitting device up to the pulling device and back need not be done. Advantageously, the reclining and sitting device and the pulling device are arranged in a support frame, so that the training device has a compact structure on the whole.
In an advantageous embodiment of the invention, the reclining and sitting device is angled at the end away from the pulling device and its height can be adjusted. This ensures that the reclining and sitting device can be adapted in optimal manner to the body structure of the particular user.
In another advantageous embodiment, first diverting rollers are arranged in guided and adjustable manner on the support frame of the invented training device, underneath the reclining and sitting device. This ensures a variable guidance of a tension cable in the diverting rollers, so that the most diverse tensile stresses can be adjusted.
BRIEF DESCRIPTION OF THE DRAWINGS
A preferred embodiment of the invented training device shall be explained more closely hereafter by means of the enclosed drawings, as an example.
These show:
FIG. 1: a schematic, partially cut perspective view of the invented training device and
FIGS. 2-4: a schematic representation of the possible applications of the invented training device.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
A training device shown in FIG. 1 in a schematic perspective view, especially one for strengthening the back muscles 10, comprises a reclining and sitting device 12 and a pulling device 14, the reclining and sitting device 12 and the pulling device 14 being arranged in a support frame 16. The reclining and sitting device 12 is fashioned like a stepboard, being angled at the end 18 away from the pulling device 14 and adjustable in height. The reclining and supporting device 12 is firmly joined to the support fram
