Exercise device with parallelogram structure having movable longitudinal bars

A device comprising a stationary mounting frame adapted to be seated on a surface, a parallelogram movably mounted on said stationary mounting frame, said parallelogram having a left and a right longitudinal bar and an upper and a lower cross bar, wherein the longitudinal bars are movable vertically and parallelly to one another against at least one resistance or weight, wherein a left hand grip and a left treading surface are mechanically coupled to the left longitudinal bar, and a right hand grip and a right treading, surface are mechanically coupled to the right longitudinal bar, in such a way that the movement of the parallelogram results in a forward movement of the left hand grip and the left treading surface, and backward movement ofthe right hand grip and the right treading surface, an upper mounting element attached in a rotatable manner to the upper cross bar of the parallelogram and a lower mounting, element attached in a rotatable manner to the lower cross bar of the parallelogram, wherein the hand grips are attached in a rotatable manner to the upper mounting, element and the treading surfaces are attached in a rotatable manner to the lower mounting element and wherein the upper mounting element comprises two upper mounting rods which form the legs of an upper triangle, and the lower mounting element comprises two lower mounting, rods which form the legs of a lower triangle.

A device comprising a stationary mounting frame adapted to be seated on a surface, a parallelogram movably mounted on said stationary mounting frame said parallelogram having a left and a right longitudinal bar and an upper and a lower cross bar, wherein the longitudinal bars are movable vertically and parallelly to one another against at least one resistance or weight, wherein a left hand grip and a left treading surface are mechanically coupled to the left longitudinal bar, and a right hand grip and a right treading surface are mechanically coupled to the right longitudinal bar, in such a way that the movement of the parallelogram results in a forward movement ofthe left hand grip and the left treading surface, and backward movement of the right hand grip and the right treading surface, an upper mounting element attached in a rotatable manner to the upper cross bar of the parallelogram and a lower mounting element attached in a rotatable manner to the lower cross bar of the parallelogram, wherein the hand grips are attached in a rotatable manner to the upper mounting element and the treading surfaces are attached in a rotatable manner to the lower mounting element, wherein the upper mounting element comprises an upper mounting rod running parallel to the upper cross bar of the parallelogram and the lower mounting element comprises a lower mounting rod running parallel to the lower cross bar of the parallelogram, and wherein the lower mounting element further comprises a buttress having at least one roller which can be moved against a rolling surface attached to the stationary mounting frame wherein said buttress is disposed on the lower mounting rod.

A device comprising a stationary mounting frame adapted to be seated on a surface, a parallelogram movably mounted on said stationary mounting frame, said parallelogram having a left and a right longitudinal bar and an upper and a lower cross bar, wherein the longitudinal bars are movable vertically and parallely to one another against at least one resistance or weight, wherein a left hand grip and a left treading surface are mechanically coupled to the left longitudinal bar, and a right hand grip and a right treading surface are mechanically coupled to the right longitudinal bar, in such a way that the movement of the parallelogram results in a forward movement of the left hand grip and the left treading surface, and backward movement of the right hand grip and the right treading surface, an upper mounting element attached in a rotatable manner to the upper cross bar of the parallelogram and a lower mounting element attached in a rotatable manner to the lower cross bar of the parallelogram, wherein the hand grips are attached in a rotatable manner to the upper mounting element and the treading surfaces are attached in a rotatable manner to the lower mounting element, and wherein each of the upper and lower mounting elements is trapezoidal and has a wide lower edge, side wide lower edge of the upper mounting element forming the upper cross bar of the parallelogram and side wide lower edge of the lower mounting element forming the lower cross bar of the parallelogram.
