DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to an exercise apparatus, comprising a two-piece plane provided with a linkage for folding the pieces of the plane to an angle relative to each other. Such exercise apparatus further includes means for locking the plane in an upright position, for supporting the plane as a horizontal plane and for supporting the plane as an inclined plane.
BACKGROUND ART
The above type of exercise apparatus is known from U.S. Pat. No. 4,759,539 in the name of the present inventor. In this prior solution, the lower section of an exercise apparatus is provided with a linkage, which is fixed relative to the exercise apparatus and elevated from the floor and around which a two-piece plane is revolved in a vertical plane for bringing the exercise apparatus into a variety of functional positions. This prior solution set forth in the patent cited above is advantageous provided that there are no restrictions set, for example, by room height. In low-ceilinged premises like basements, due to the installation of a fixed linkage above the floor, the length of a two-piece plane cannot be made functionally sufficient.
SUMMARY OF THE INVENTION
An object of this invention is to provide an exercise apparatus, which is particularly suitable for low-ceilinged premises, for example, basement rooms, and whose exercise planes are sufficiently long even though room height may induce restrictions. In addition, an exercise apparatus of the invention has certain extra features compared to the prior art, and is an advantageous exercise apparatus.
In order to achieve this object, an exercise apparatus of the invention includes a fixed linkage in the lower section of an exercise apparatus which is adapted for mounting on a fixed base, such as a floor. The linkage of the two-piece plane is provided with locking means and the upper section of the exercise apparatus carries an extending member adapted to serve as a support pedestal.
This solution provides an exercise apparatus, the functional length of whose two-piece plane begins immediately at floor surface. By means of the linkage locking means of a two-piece plane the exercise apparatus can be set in positions suitable for various workout exercises, such as in a horizontal plane and in an inclined plane, whereby the latter, due to a possibility of locking the linkage, can even be set in at least two angular positions. The extending member in the upper section of the exercise apparatus serves as a support pedestal in all lowered positions of the exercise apparatus in a manner that the outermost portion of such extending member supports itself against the floor.
The invention will now be described in more detail with reference made to an embodiment shown in the accompanying drawings. In the drawings;
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of an exercise apparatus in an upright position,
FIG. 2 is a perspective view of an exercise apparatus in a second position, the apparatus being fitted in a horizontal plane and to be used, for example, as a table top or for dorsal muscle workouts,
FIG. 3 is another perspective view of an exercise apparatus in its third position, which is at the same time a first position for using the exercise apparatus as an inclined plane, and
FIG. 4 is also a perspective view of an exercise apparatus in a fourth position, which is a second position for using the exercise apparatus as an inclined plane which, similarly to the position of FIG. 3, is intended for abdominal muscle workouts.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
As shown in the drawings, the exercise apparatus of the present invention can be used to perform a great variety of workout exercises as the exercise apparatus can be handily set in various positions. For example, when fastened to a wall S in an upright position shown in FIG. 1, the exercise apparatus provides so-called ladder rungs P and the additional feature for use this position is a horizontal bar R. From the position shown in FIG. 1 the upper piece 2 of
