摘要

Apparatus for exercising the muscles of the legs, characterized in that it is configured from a structure (2) comprising a support frame where the user stands by supporting the body in it, and in the lower part of which there are two platforms (3) mobiles on which said user puts his feet, a support element (4) for the legs of the user being provided attached to each platform (3). Apparatus for exercising the leg muscles according to claim 1, characterized in that the support elements (4) are rigid parts fixed integrally to each platform (3), rising vertically up to a certain height. Apparatus for exercising the muscles of the legs, according to claim 1 or 2, characterized in that the support elements (4) are provided with concave pads (4a) designed to receive the anterior part of the leg. 4. Apparatus for exercising the muscles of the legs, according to claim 1, characterized in that the structure (2), is composed of metal profiles that form a prismatic body open, at least, superiorly. 5. Apparatus for exercising the muscles of the legs, according to claims 1 and 4, characterized in that the structure (2) incorporates a cross-bar grip (5) that facilitates the user's incorporation into the apparatus. Apparatus for exercising the muscles of the legs, according to any of claims 1, 4 or 5, characterized in that, in the upper and rear part of the structure (2) has a foldable back bar (6) with a backrest (7). ), which, in the open position, allows the user access to the interior of the structure (2) and, once closed, provides the point of support for the user's back. 7. Apparatus for exercising the muscles of the legs, according to claims 1 and 2, characterized in that the platforms (3) have a passive tilting movement, that is, caused by the user pressing on them. 8. Apparatus for exercising the muscles of the legs, according to claims 1, 2 and 7, characterized in that the platforms (3) are fixed to the base (2a) of the structure (2) by its rear end, in an articulated point (8) where they swing around a horizontal axis, and at the opposite and anterior end are joined, at a higher point of the structure (2), to elastic means that allow the independent movement of the same when the user presses on they, and that tend to return them to their initial inclined position, when it stops doing it. 9. Apparatus for exercising the muscles of the legs, according to claim 8, characterized in that the elastic means are two springs (9). 10. Apparatus for exercising the leg muscles according to any of claims 1, 2, 7 and 8, characterized in that, in addition, the platforms (3) have a passive sliding movement, caused by the user. 11. Rare apparatus exercise the leg muscles, according to claims 1, 2, 7, 8 and 10, characterized in that, at its rear, the platforms (3) are fixed, with the articulated point (8) where they swing in an axle, sliding skids (10) inserted in horizontal guides (11) fixed together at the base of the structure (2). 12. Apparatus for exercising the muscles of the legs, according to claims 1, 2, 7, 8, 10 and 11, characterized in that the platforms (3) have an autonomous movement assisted by a motorized mechanism (13). 13. Apparatus for exercising the muscles of the legs, according to claim 12, characterized in that the motorized mechanism (13) is an electric connecting rod mechanism, type bottom bracket, to which the ends of the platforms (3) are attached by their front end, end that extends beyond the front of the structure (2) where said mechanism is coupled. 14. Apparatus for exercising the muscles of the legs, according to claims 1, 2, 7, 8, 10 to 13, characterized in that the platforms (3) are fixed at their rear end, with an articulated point (8) where they swing around of a horizontal axis, sliding skids (10) inserted in horizontal guides (11) fixed together at the base of the structure (2), and at the front end are joined, respectively, on both sides of the connecting rod housing the motorized mechanism (13) in a circular housing (14). 15. Apparatus for exercising the leg muscles according to any of claims 12 to 14, characterized in that the motorized mechanism (13) has an upper console (15) with the control controls for starting, stopping and speed selection. By the user. 16. Apparatus for exercising the muscles of the legs, according to any of claims 12 to 15, characterized in that the motorized mechanism (13) is incorporated in a frame (16) independent of the structure (2), allowing its disengagement from the same. 17. Apparatus for exercising the muscles of the legs, according to claim 16, characterized in that, when the motorized mechanism (13) is uncoupled, the platforms (3) then allow them to incorporate elastic means, for example springs (9), fixed to their previous part to be able to move them the own user.
