Wiggle stepper

Abstract

A wiggle stepper includes a base member, an adjust seat mounted on the base member, two platforms respectively pivotally mounted to the base member, a connector for connecting the platform and a cylinder that is mounted between the platform and the base member. Each platform is moved upwardly and downward, and wiggled obliquely to prevent the moving route of the platform from forming a dead space for user to smoothly operate the two platforms. The user can adjust the position of the adjust seat for adjusting the tension from the adjust seat according to the physical strength of the user.

1 . A wiggle stepper comprising: 
 a base member having a seat mounted on a front portion of the base member, the seat including a plate perpendicularly upwardly secured on a front end of the base member and two cubic posts mounted on a top of the plate, the two cubic posts adjacent and parallel to each other, and extending toward a rear end of the base member, each cubic post including a front end having a pivot upwardly and outwardly mounted thereon, a bolt screwed through the plate from the front end of the base member and a pin laterally secured on a middle portion of the base member;    an adjust seat slidably mounted on the base member under the two cubic post, the adjust seat including a U-shaped frame with one end pivotally connected to the bolt, a shaft longitudinally secured on a bottom of the frame for pivotally mounted a damping wheel within the adjust seat;    two platforms respectively pivotally mounted to the base member, each platform having a first end sleeved on a corresponding one of the two pivots, a crank formed on a front section of each of the two platforms, a cable having two opposite ends respectively secured on the two cranks and coiled on the damping wheel to make the two platforms moved contrary relative to each other, each crank having a connecting seat mounted thereon for connecting to the connector;    a connector for connecting the platform and a cylinder that is mounted between the platform and the base member, the connector including a first end having a first pivot hole defined therein and a second end having a second pivot hole defined therein, the first pivot hole and the second pivot hole perpendicularly correspond to each other, the first end of the connector pivotally received in the connecting seat by a pin extending through the connecting seat and the first pivot hole in the first end of the connector, an linkage having a first end pivotally mounted to the second end of the connector due to the second pivot hole; and    a cylinder having a first end pivotally connected to a second end of the linkage and a second end pivotally mounted to a corresponding end of the pin.    
     
     
         2 . The wiggle stepper as claimed in  claim 1 , wherein the base member has a V-shaped groove defined under the two cubic posts due to the shape of the two cubic posts.  
     
     
         3 . The wiggle stepper as claimed in  claim 1 , wherein the linkage is H-shaped.  
     
     
         4 . The wiggle stepper as claimed in  claim 2 , wherein the adjust seat includes a guiding portion formed on the top of the frame and having a shape corresponding to that of the V-shaped groove under the two cubic posts.
