Waist training machine

Abstract

A waist training machine comprises a base; a swing seat, an upper side thereof being installed with a transfer wheel retainer, and another end thereof being installed with a crank retaining seat; a swing unit installed below the swing seat for driving the swing seat to move leftwards and rightwards; a transfer wheel set having a driving wheel and two cranks at two sides; a crank having a first linkage and a second linkage pivotally connected to the first linkage; a driving unit having at least one servo motor for driving the transfer wheel set to rotate; and a saddle combined to the first linkage of the crank. By aforementioned elements, the saddle can move forwards and forwards, upwards and backwards, and leftwards and rightwards.

1 . A waist training machine comprising:
 a base;   a swing seat swingable leftwards and rightwards, an upper side thereof being installed with a transfer wheel retaining seat, and another end thereof being installed with a crank retainer;   a swing unit installed below the swing seat for driving the swing seat to move leftwards and rightwards;   a transfer wheel set having a driving wheel and two crank wheels at two sides; a rotary shaft combined to the driving wheel and the crank wheels; by combination of the rotary shaft and the swing seat, the waist training machine is rotatable;   a crank having a first linkage and a second linkage pivotally connected to the first linkage; a free end of the first linkage being combined to an eccentric position of a crank wheel of the transfer wheel set; and a free end of the second linkage being combined to the crank retaining seat;   a driving unit having at least one servo motor for driving the transfer wheel set to rotate; and   a saddle combined to the first linkage of the crank;   wherein by above mentioned elements, the saddle can move forwards and forwards, upwards and backwards, and leftwards and rightwards.   
   
   
       2 . The waist training machine as claimed in  claim 1 , further comprising an adjusting device for adjusting the eccentricity of the free end of the first linkage with respect to the crank wheel so that the swing amplitude of the crank is adjustable; the adjusting device being formed by a servo motor and a guide rod; the guide rod is screwed with a sliding block so that the servo motor is combined to an outer middle portion of the crank wheel and the guide rod is at a radial extension position of the crank wheel; the sliding block  63  is embedded to a radial track; if the free end of the first linkage is rotatably combined to the sliding block; the servo motor will be used to drive the guide rod so that the sliding block and the second linkage can be used to adjust the eccentricity. 
   
   
       3 . The waist training machine as claimed in  claim 1 , wherein the driving unit has a servo motor which is combined to a predetermined position at a lower side of the swing seat; a power output shaft of the driving unit is combined with a first driving wheel; the first driving wheel and a belt passing through the slot will drive the driving wheel of the transfer wheel set. 
   
   
       4 . The waist training machine as claimed in  claim 1 , wherein the driving unit has a servo motor which is combined to a predetermined position at a lower side of the swing seat; a power output shaft of the driving unit is combined with a first driving wheel; the first driving wheel and a belt passing through the slot will drive the driving wheel of the transfer wheel set; a transfer shaft passes through the transfer axial seat so that the two ends of the transfer shaft extend to the rotary wheels of the swing unit; the second driving wheel at two ends will transfer the power from the servo motor and the transfer shaft to the rotary wheels. 
   
   
       5 . The waist training machine as claimed in  claim 1 , wherein front and rear ends of the upper sides of the base are installed with respective first pivotal portions; two ends thereof are installed with respective second pivotal portions which are combined to the first pivotal portions. 
   
   
       6 . The waist training machine as claimed in  claim 1 , wherein an upper end of the swing seat is formed with a penetrating slot; upper ends of the two sides of the slot are installed with respective retaining seats for the transfer wheel set; another end thereof is installed with at least one crank retaining seat; a bottom of the swing seat is installed with a plurality of aligned transfer axial seats. 
   
   
       7 . The waist training machine as claimed in  claim 1 , wherein the swing unit has two limiting plates which are fixed to the two upper ends of the base; each limiting plate has a limiting trench; two rotary wheels are combined to the predetermined positions of the transfer axial seat below the swing seat; each rotary wheel is at a lateral side of the limiting plate; an eccentric position at a lateral surface of each rotary wheel has a pin; the pin passes through the limiting trench; a bearing is installed to the pin so that a periphery of the bearing is matched to the limiting trench; thereby when the rotary wheel is driven by a power source, the swing seat swings leftwards and rightwards. 
   
   
       8 . The waist training machine as claimed in  claim 1 , wherein the saddle is a seat for supporting a user; the saddle has an Ω shape cylinder; two lateral walls of an open end of the cylinder are combined to the saddle retainer of the first linkage; the cylinder is further installed with a cushion.
