Climbing exerciser

Abstract

A climbing exerciser includes a base mount, and left and right racks respectively located at left and right sides of the base mount and reciprocatingly moveable up and down. The left rack has a lower left member and an upper left member swivelable relative to the lower left member between a first outer position and a first inner position. The right rack has a lower right member and an upper right member swivelable relative to the lower right member between a second outer position and a second inner position. By adjusting the postures of the upper left and right members relative to the lower left and right members respectively, the climbing exerciser can shift exercise mode from one to another. Further, the climbing exerciser can provide smooth and more natural movements to the user with low noise.

What is claimed is: 
     
         1 . A climbing exerciser comprising:
 a base mount;   a left rack having a lower left member disposed at a left side of the base mount and configured in a way that the lower left member is reciprocatingly moveable up and down relative to the base mount, and an upper left member provided with a left grip and pivotally connected with the lower left member in a way that the upper left member is swivelable relative to the lower left member between a first outer position and a first inner position; and   a right rack having a lower right member disposed at a right side of the base mount and configured in a way that the lower right member is reciprocatingly moveable up and down relative to the base mount, and an upper right member provided with a right grip and pivotally connected with the lower right member in a way that the upper right member is swivelable relative to the lower right member between a second outer position and a second inner position;   wherein the climbing exerciser is configured in a way that the left grip is spacedly located at a left side of the right grip when the upper left member stays at the first outer position and the upper right member stays at the second outer position, or in a way that the left grip is spacedly located at a right side of the right grip when the upper left member stays at the first inner position and the upper right member stays at the second inner position.   
     
     
         2 . The climbing exerciser as claimed in  claim 1 , wherein the upper left member is swivelable about a first imaginary axis relative to the lower left member, and the upper right member is swivelable about a second imaginary axis relative to the lower right member; the first imaginary axis is substantially parallel to the second imaginary axis. 
     
     
         3 . The climbing exerciser as claimed in  claim 2 , wherein the first imaginary axis is substantially parallel to the left rack, and the second imaginary axis is substantially parallel to the right rack. 
     
     
         4 . The climbing exerciser as claimed in  claim 1 , further comprising a motion linking device disposed to the base mount and linked with the left rack and the right rack in a way that the right rack lowers when the left rack raises. 
     
     
         5 . The climbing exerciser as claimed in  claim 1 , wherein the upper left member is provided with a transversally extending hole, into which a left handlebar is inserted to form the left grip. 
     
     
         6 . The climbing exerciser as claimed in  claim 5 , wherein the transversally extending hole of the upper left member is a through hole. 
     
     
         7 . The climbing exerciser as claimed in  claim 1 , wherein the lower left member is provided with a left pedal, and the lower right member is provided with a right pedal. 
     
     
         8 . The climbing exerciser as claimed in  claim 1 , further comprising:
 two left links each having a first end pivotally connected with the base mount, and a second end pivotally connected with the left rack, such that the left rack is reciprocatingly moveable up and down relative to the base mount; and   two right links each having a first end pivotally connected with the base mount, and a second end pivotally connected with the right rack, such that the right rack is reciprocatingly moveable up and down relative to the base mount.   
     
     
         9 . The climbing exerciser as claimed in  claim 8 , wherein the two left links are parallel to each other, and the two right links are parallel to each other. 
     
     
         10 . The climbing exerciser as claimed in  claim 4 , wherein the motion linking device comprises a plurality of pulleys disposed to the base mount, and a flexible member wound around the pulleys in a way that the flexible member has a first end connected with the left rack, and a second end connected with the right rack. 
     
     
         11 . The climbing exerciser as claimed in  claim 1 , further comprising a resistance device disposed to the base mount to provide a resistance force against movements of the left rack and the right rack. 
     
     
         12 . The climbing exerciser as claimed in  claim 1 , wherein the base mount has a height substantially equal to heights of the left lower member and the right lower member.
