ABSTRACT:
BACKGROUND OF THE INVENTION
Sports and fitness devices, such as they are used, for example, as home equipment or in fitness studios, are generally designed in such a way that specific muscle groups are stressed in a targeted manner. For training at home or in the fitness studio, a large number of special apparatus is necessary, if one wishes to work the entire body uniformly. This is particularly a disadvantage if one would like to train at home because purchasing various training devices often is limited by the high price of such equipment and lack of space.
The object of the present invention is to present a sports device, with which several different muscle groups can be stressed or worked simultaneously.
SUMMARY OF THE INVENTION
The invention comprises a sports or exercise device with a mounting frame and a parallelogram structure with left and right longitudinal bars and upper and lower crossbars, whereby the longitudinal bars can be moved vertically and parallely relative to one another against at least one resistance and/or at least one weight. A left hand grip and a left treading surface are assigned to the left longitudinal bar and a right hand grip and a right treading surface are assigned to the right longitudinal bar, in such a way that the movement of the parallelogram structure results in a forward motion of the left hand grip and the left treading surface and a reverse motion of the right hand grip and the right treading surface, and vice versa.
The construction of the device according to the invention thus leads to a course of movement in which simultaneously the left leg and the left arm are moved upward and the right leg and the right arm are moved downward, and in fact, against a weight. Either only the arms or only the legs, or both the arms and legs can be simultaneously worked against the weight. The course of movement is comparable with climbing stairs or mountain climbing. Thus, the musculature of the arms, the legs, the back, the chest and the shoulder girdle as well as the buttocks region can be worked simultaneously.
The sports device according to the invention can be produced in different sizes and constructed such that it can be easily disassembled and reassembled. The present device is particularly suitable for home use. However, it may also be used in a larger setting, e.g., as a professional training device, for example, in fitness studios. The present device also may be used for medical purposes, such as for checking fitness or EKG measurement. According to the invention, almost all important muscle groups are stressed simultaneously, thus more precise results can be obtained with such measurements than with previously used home trainers such as stationary bicycle devices or stair climbing devices.
The arrangement of the hand grips and treading surfaces can be made in different ways. For example, the hand grips and treading surfaces may be attached directly to the parallelogram structure, for example to the longitudinal bars or to the cross bars. They also may be joined indirectly to the parallelogram by attaching them to one or more mounting elements, which in turn are attached to or joined with the parallelogram. In a currently preferred embodiment, these mounting elements, for aesthetic reasons, are shaped as equilateral triangles. However, any shape may be used, including, without limitation, squares, rectangles, circles or other triangular shapes.
The weight is preferably in the form of one or more pneumatic or hydraulic cylinders, whereby one of the ends of each cylinder is attached to the mounting frame and the other end of each cylinder is attached to the parallelogram or to one or more mounting elements. In this way, the parallelogram can be moved against the restoring force exerted by the cylinders.
Examples of embodiments of the present invention are explained in more detail below with reference to the attached drawings.
