Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

The chest expander convenient for exercising leg muscles as shown in figures 1-2 comprises a cross rod 1, wherein two ends of the cross rod 1 are both vertically connected with supporting rods 12, and the edges of the supporting rods 12 and the cross rod 1 are both arc transition edges. The arrangement of the struts 12 at the ends of the crossbar 1 increases the stability of the crossbar 1 when positioned.

The bottom both sides of horizontal pole 1 all are equipped with spring tension mechanism, and spring tension mechanism is including connecting plate 11 and hanger plate 10 that are parallel to each other, are connected with pull rod 2 between connecting plate 11 and the horizontal pole 1 perpendicularly, and the both sides of hanger plate 10 all are connected with screw rod 3 perpendicularly, and screw rod 3 runs through connecting plate 11 and tip threaded connection have movable nut 4, and connecting plate 11 is connected with rings 6 through a plurality of elastic connection mechanisms. The bottom inner wall of rings 6 is fixedly connected with footboard 7, and the equipartition has hemispherical arch 13 on the footboard 7. The pedal 7 is provided with the bulges 13 which can play the roles of preventing skidding and massaging the feet.

The lifting ring 6 is used for treading on feet to achieve the purpose of exercising leg muscles, the cross rod 1 is used for positioning one end of the chest developer, can be placed on a frame and also can be held by hands to achieve the purpose of exercising arm muscles simultaneously; through changing the position of movable nut 4 on screw rod 3, can change the position between hanger plate 10 and horizontal pole 1 to the convenience is adjusted according to user's height size, reaches better exercise effect.
