Hanging slider

Abstract

A hanging slider includes a main body ( 100 ), an axle shaft ( 210 ), two wheel members ( 220/230 ) and a plurality of roller bearings ( 300 ). The main body ( 100 ) includes a hollow member ( 110 ) and a hooking member ( 130 ). The axle shaft ( 210 ) penetrates through the hollow member ( 110 ). The two wheel members ( 220/230 ) are arranged on two ends of the axle shaft ( 210 ) and are positioned outside of the hollow member ( 110 ) respectively. The roller bearings ( 300 ) are received inside the hollow member ( 110 ); each roller bearing ( 300 ) is parallel to the axle shaft ( 210 ) and supports between the hollow member ( 110 ) and the axle shaft ( 210 ); the roller bearings ( 300 ) are arranged to circumference the axle shaft ( 210 ). With the linear contacts formed among the roller bearings ( 300 ) and the hollow member ( 110 ) as well as the axle shaft ( 210 ), the useful lifetime of the hanging slider is prolonged.

         2 . The hanging slider according to  claim 1 , wherein two ends of the hollow member ( 110 ) include an opening ( 101 / 102 ) formed thereon respectively; each one of the wheel members ( 220 / 230 ) covers onto the corresponding openings ( 101 / 102 ) respectively. 
     
     
         3 . The hanging slider according to  claim 1 , wherein each one of the roller bearings ( 300 ) extends between the two wheel members ( 220 / 230 ) respectively. 
     
     
         4 . The hanging slider according to  claim 1 , wherein one of the wheel members ( 220 / 230 ) is formed at one of the two ends of the axle shaft ( 210 ). 
     
     
         5 . The hanging slider according to  claim 4 , wherein another one of the wheel members ( 220 / 230 ) is locked onto another end of the two ends of the axle shaft ( 210 ). 
     
     
         6 . The hanging slider according to  claim 1 , wherein the hollow member ( 110 ) includes an inner wall surface ( 111 ) formed therein; the axle shaft ( 210 ) includes an outer surface ( 211 ); a lateral side of each one of the roller bearings ( 300 ) abuts against the inner wall surface ( 111 ) of the hollow member ( 110 ) and the outer surface ( 211 ) of the axle shaft ( 210 ). 
     
     
         7 . The hanging slider according to  claim 6 , wherein the inner wall surface ( 111 ) of the hollow member ( 110 ) includes a plurality of rounded slot ( 112 ) formed axially and spaced apart from each other; each one of the roller bearings ( 300 ) is received inside each one of the rounded slots ( 112 ) respectively. 
     
     
         8 . The hanging slider according to  claim 1 , wherein the main body ( 100 ) includes a pivotal attachment portion ( 120 ); the hooking member ( 130 ) is pivotally attached to the pivotal attachment portion ( 120 ). 
     
     
         9 .
