Abstract:
A body exerciser comprising:a base frame including a pair of support rods, each having a first proximate end, a first distal end and a first intermediate portion interposed therebetween, each of said first proximate and distal ends and said first intermediate portion being disposed to be spaced apart from a respective one of said first proximate and distal ends and said first intermediate portion of the other one of said support rods in a first transverse direction;a handle frame including a pair of bendable handle rods, each having a second proximate end, a second distal end and a second intermediate portion which is bendable and interposed therebetween, each of said second proximate and distal ends and said second intermediate portion being disposed to be spaced apart from a respective one of said second proximate and distal ends and said second intermediate portion of the other one of said bendable handle rods in the first transverse direction;a pair of first coupling members, each disposed on said first proximate end of a respective one of said support rods, and having first outer abutment and inner engaging walls opposite to each other in the first transverse direction, and a first through hole extending to communicate said first outer abutment wall with said first inner engaging wall to define a first axis;a pair of second coupling members, each disposed on said second proximate end of a respective one of said handle rods, and having second outer abutment and inner engaging walls opposite to each other in the first transverse direction, and a second through hole extending to communicate said second outer abutment wall with said second inner engaging wall to define a second axis, said second inner engaging wall being disposed to face and to be rotatable relative to said first inner engaging wall of a respective one of said first coupling members about both said first and second axes;a pair of retaining sets, each of said retaining sets including a plurality of retaining members which are disposed between said first and second inner engaging walls to lock said second inner engaging wall from rotation relative to said first inner engaging wall in a tightened state, said retaining member being further disposed to be angularly spaced from one another and around said first and second axes such that relative rotation about said first and second axes between said first and second inner engaging walls is permitted only in a loosened state when said second inner engaging wall has been brought in the first transverse direction, away from and to steer clear of said first inner engaging wall;a pair of biasing members, each disposed to bias said second inner engaging wall of one of said second coupling members to move away from said first inner engaging wall of one of said first coupling member;a pair of tightening rods, each including an abutment end and a pivot end, and disposed to be inserted into respective ones of said first and second through holes such that when said abutment end is brought to abut against one of said first and second outer abutment walls, said pivot end extends outwardly of the other one of said first and second outer abutment walls in the first transverse direction; anda pair of locking members, each disposed to be pivotally mounted on said pivot end of a respective one of said tightening rods about a pivot axis, and including first and second cam surfaces disposed proximate to said pivot axis, and an anchoring end disposed distal to said pivot axis such that when said first cam surface is brought to face said other one of said first and second outer abutment walls, said second inner engaging wall is in the loosened state, and when said anchoring end is turned about said pivot axis to anchor on said other one of said first and second outer abutment walls, said second cam surface will be brought to move against biasing action of a respective one of said biasing members to abut against said other one of said first and second outer abutment walls so as to place said second inner engaging wall in the tightened state.
