Ball-bearing slide carriage device

Abstract

A ball-bearing slide carriage device comprising (a) a ball-bearing slide carriage which has an inner space and is provided with a plurality of filling slots, buffering open channels located at ends and outside the filling slots and adjoining buffer terminals at outermost ends of the ball-bearing slide carriage and (b) a plurality of balls positioned in the filling slots and used in providing relative sliding effect. As such, the ball-bearing slide carriage depending on the buffering open channels for sliding and stopped at terminal points generates neither noises nor vibrations and features superior buffer quality, quiet effect, durability and fewest troubles.

What is claimed is: 
     
         1 . A ball-bearing slide carriage device, comprising:
 A ball-bearing slide carriage which has an inner space and is provided with (a) a plurality of filling slots, (b) buffering open channel located at two ends and outside said filling slots and adjoining buffer terminals at outermost ends of said ball-bearing slide carriage;   A plurality of balls positioned in said filling slots and used in providing relative sliding effect.   
     
     
         2 . The ball-bearing slide carriage device according to  claim 1  wherein said ball-bearing slide carriage comprises a top face part and two side face parts for development of an end-to-side face part between said top face part and said side face part and two bottom hook parts extending inward from said side face parts to develop an open channel between said two bottom hook parts for connecting said inner space. 
     
     
         3 . The ball-bearing slide carriage device according to  claim 2  wherein said filling slots are located at both sides of said top face part. 
     
     
         4 . The ball-bearing slide carriage device according to  claim 2  wherein said filling slots are located at said end-to-side face part. 
     
     
         5 . The ball-bearing slide carriage device according to  claim 1  wherein said filling slots link said inner space. 
     
     
         6 . The ball-bearing slide carriage device according to  claim 1  wherein said buffering open channel link said inner space. 
     
     
         7 . The ball-bearing slide carriage device according to  claim 1  further comprises a bottom track and a central track: said bottom track comprises a track part and a mounted plate wherein said track part has a slide track space inside, said bottom track is equipped with a limiting member in the front of said slide track space, said central track slides and is held in said slide track space, and said ball-bearing slide carriage is installed between said bottom track and said central track. 
     
     
         8 . The ball-bearing slide carriage device according to  claim 7  wherein said central track further comprises a central track bottom as well as a central track top and said central track bottom slides and is held in said slide track space. 
     
     
         9 . The ball-bearing slide carriage device according to  claim 7  wherein said central track bottom is equipped with a limiting member at the front (or rear) end and said central track top is also equipped with a limiting member at the front (or rear) end. 
     
     
         10 . The ball-bearing slide carriage device according to  claim 9  further comprises an outer track which completes a slide action relative to said central track and coordinates said central track for installation of said ball-bearing slide carriage device in between. 
     
     
         11 . The ball-bearing slide carriage device according to  claim 10  wherein said outer track has a slide track space in which said central track top slides and is held and is provided with a limiting member at the rear end.
