Exercise Device with Length Adjustable Leg

Abstract

An exercise device is provided with a frame assembly including an inclined first leg including a stop member proximate a bottom end, and a mounting member at a top end; and an inclined second leg and including a support tube, a sliding tube slidably put on the support tube and having a top end pivotably secured to the mounting member, and a resilient detent in the support tube for locking the sliding and support tubes before and after length adjustment of the second leg; two opposite handlebars; and a sliding assembly including a sliding member slidably mounted on the first leg and being capable of sliding in a range from a position proximate the mounting member to the stop member, a left knee rest secured to left side of the sliding member, and a right knee rest secured to right side of the sliding member.

What is claimed is: 
     
         1 . An exercise device comprising:
 a frame assembly comprising a first leg including a stop member proximate a bottom end, and a mounting member at a top end; and a second leg inclined at an angle with respect to the first leg and comprising a support tube including a first end hole facing the first leg and a second end hole opposite to the first end hole, a sliding tube slidably put on the support tube and having a top end pivotably secured to the mounting member, the sliding tube including a plurality of first holes facing the first leg and a plurality of second holes opposite to the first holes, and a resilient detent disposed in the support tube and including two end projections wherein one projection passes through the first end hole into the aligned first hole to be locked and the other projection passes through the second end hole into the aligned second hole to be locked, and wherein the projections can be pressed toward each other to clear the first hole and the second hole respectively so as to be capable of sliding the sliding tube to lock the projections in another pair of the first and second holes respectively;   two opposite handlebars each including a padding member at one end proximate the mounting member; and   a sliding assembly comprising a sliding member slidably mounted on the first leg and being capable of sliding in a range from a position proximate the mounting member to the stop member, a front axis passing through one side of the sliding member and through the other side thereof, a rear axis passing through one side of the sliding member and through the other side thereof, a padded left knee rest secured to both the front and rear axes and including a surface recess, and a padded right knee rest secured to both the front and rear axes and including a surface recess.   
     
     
         2 . The exercise device of  claim 1 , wherein the sliding member comprises a front grooved wheel rotatably mounted on a front end of bottom of the sliding member and being capable of rolling on the first leg, a rear grooved wheel rotatably mounted on a rear end of the bottom of the sliding member and being capable of rolling on the first leg, and an intermediate grooved wheel rotatably mounted on an intermediate portion of the bottom of the sliding member and capable of rolling on the bottom of the first leg.
