Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to an athletic apparatus, and more particularly to an athletic apparatus including a pair of non-linear sliding tracks movable relative to the supporting base and having a pair of foot pedals slidably attached or mounted on the tracks for supporting the user's legs or feet and for allowing the user to conduct an elliptical moving or stepping or walking exercise or operation.
2. Description of the Prior Art
Typical athletic apparatuses or exercise devices comprise a pair of rotatably positionable tracks each having a stirrup movable back and forth thereon for supporting the user's legs or feet and for allowing the user to conduct sliding or skiing or skating or other types of exercise operations.
For example, U.S. Pat. No. 4,781,372 to McCormack, U.S. Pat. No. 5,741,205 to Doll et al., and U.S. Pat. No. 7,014,595 to Bruno disclose several of the typical ice-skating exercise devices each comprising a pair of rotatably positionable and angularly adjustable tracks, and a pair of foot pedals slidably attached or mounted on the tracks for supporting the user's legs or feet and for allowing the user to conduct sliding or skiing or skating or other types of exercise operations.
However, the tracks are supported horizontally relative to the supporting base and the foot pedals may not be moved along an elliptical moving stroke, or the foot pedals and the pedal members may only be moved or stepped up and down relative to the supporting base, but may not be moved along an elliptical moving stroke.
U.S. Pat. No. 7,806,808 to Kuo, and U.S. Pat. No. 8,033,961 to Kuo discloses the other typical exercise apparatus each comprising a pair of pedal members slidably attached or mounted to a supporting base with sliding tracks, and a pair of foot pedals rotatably attached or mounted to the pedal members and coupled to the supporting base with pulleys and cables for keeping the vertical motion of the foot pedals.
However, the sliding tracks and the foot pedals may not be moved or adjusted relative to each other and/or the handle may not be moved or adjusted relative to the supporting base such that the typical exercise apparatus may not be suitably actuated or operated by the users of different shape or size or dimension or height or the like.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional athletic devices or apparatuses.

As best shown in FIGS. 5 and 6, a foot support 5 is attached onto each of the carriers 35 and thus slidably attached onto the respective track 3, 4 for supporting the user, for example, the foot supports 5 each include a plate 50 having a front portion 51 pivotally attached to the ears 36 of the carrier 35 with a pivot axle 52 for allowing the plate 50 to be pivoted relative to the carrier 35 and the track 3, 4, the plates 50 each include an extension or block 53 extended downwardly from the rear portion 54 thereof and having an oblong hole 55 formed in the block 53 for slidably engaging with a stop 56 which is attached to the protrusion 37, for guiding and limiting the plate 50 to rotate relative to the carrier 35 and the track 3, 4.
A spring biased projection 57 is attached to the block 53 and engageable with either of the orifices 38, 39 of the protrusion 37 for anchoring the plate 50 to the carrier 35 at selected angular positions. The spring biased projections 57 each include a knob 58 coupled to the spring biased projections 57 for pulling and actuating or operating the spring biased projection 57 to engage with either of the orifices 38, 39 of the protrusion 37.
