DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to the general technical field of devices and appliances designed for developing and rebuilding the musculation of a person and making it possible, in particular, to perform specific sports training or reeducation of certain muscles of a person in a correct posture.
More particularly, the invention provides an appliance that is adapted to straightening lumbar lordosis by retroversion of the pelvis, while simultaneously working the abdominal, the pelvis-trochanter, and the gluteal muscles and also the muscles of the lumbar region while reclining on the front.
DESCRIPTION OF THE RELATED ART
The state of the art provides various appliances for strengthening or reeducating the muscles of the abdominal wall, of the pelvis-trochanter, gluteal muscles, and muscles of the lumbar region. Thus, it is well known to use stall bars or other accessories for holding the feet in place while performing movements that exercise the abdominal, gluteal, and lumbar muscles. It is also well known to use a conventional abdominal plank, a lumbar chair, a foam roller, a cushion, or a floor mat, for the purpose of performing various exercises often undertaken on the advice of a specialist. Another solution consists in using a special-purpose variable-load muscle-building machine.
In use, the above-described appliances have led to the observation that they suffer from undeniable practical difficulties. To be effective some of those appliances need a qualified person to be present in order to ensure that proper retroversion of the pelvis is executed or in order to ensure that muscle-building movements are performed properly and without danger with respect to abdominal, pelvis-trochanter, gluteal, or lumbar muscles. Those appliances do not make it possible to perform special work for the purpose of obtaining synergy and proper balance of the muscles concerned while also correcting the movements performed.
In addition, known appliances often take up a lot of space, are expensive to buy, or cater for a limited range of exercises only.
SUMMARY OF THE INVENTION
The present invention seeks to remedy the above-specified drawbacks by proposing, in particular, an appliance that provides hypercorrective work for abdominal wall, pelvis-trochanter, and gluteal muscles by retroversion of the pelvis while straightening the lumbar spine in the general sense and also suitable for use in a small amount of space.
The invention also seeks to provide an appliance enabling a person to work specifically on the abdominal, pelvis-trochanter, gluteal, and lumbar muscles specifically without risk of trauma, even in the absence of advice from a qualified person and without prior knowledge of biomechanical and muscle-strengthening techniques.
The invention also seeks to alleviate compression on the disks between the vertebrae by straightening the lumbar region.
To achieve these objects, the muscle-building appliance of the invention is implemented in the form of a shaped, rigid, and inextensible structure having in succession in a given direction on a longitudinal axis of symmetry: extent, that is situated on the axis of symmetry, and that has a forwardly-open recess; angle with the preceding zone; raised relative to the pubic support zone, located on either side of the abdominal recess, and symmetrical about the axis of symmetry; and and movement trajectory, and comprising: a tilting angle for the pelvis.
Various other characteristics appear from the following description given with reference to the accompanying drawings which show embodiments of the invention as non-limiting examples.
