Drawer slide assembly

Abstract

A drawer slide assembly includes an upper slide; an inner slide having a buffer unit located therein; at least two upper sliding guides being provided on top and bottom with first sliding bearings to bear against upper inner and lower inner surfaces of the upper slide and upper inner and upper outer surface of the inner slide, and on a lateral wall with second sliding bearings to bear against a lateral inner surface of the upper slide and a lateral upper outer surface of the inner slide, so that the upper slide and the inner slide are mutually slidably assembled to each other; and a mounting plate for holding the assembled upper slide and inner slide to a fixed place. With the sliding bearings so arranged, the drawer slide assembly provides a buffering effect to enable smooth and stable opening and closing of a drawer box.

       2 . The drawer slide assembly as claimed in  claim 1 , wherein the upper slide is formed on the upper inner and lower inner surfaces with a plurality of axially extended first slide ways, and the inner slide is formed on the upper outer and upper inner surfaces with a plurality of axially extended second slide ways to correspond to the first sliding bearings. 
   
   
       3 . A drawer slide assembly, comprising:
 an upper slide;   an inner slide;   at least two upper sliding guides being provided on a top and a bottom with a plurality of first sliding bearings, and on a lateral wall with a plurality of second sliding bearings, such that the first sliding bearings on the top of the upper sliding guides bear against an upper inner surface of the upper slide and an upper outer surface of the inner slide, the first sliding bearings on the bottom of the upper sliding guides bear against a lower inner surface of the upper slide and an upper inner surface of the inner slide, and the second sliding bearings bear against a lateral inner surface of the upper slide and a lateral upper outer surface of the inner slide, causing the upper slide and the inner slide to mutually slidably assemble to each other;   a lower slide having a buffer unit fixedly located thereabove;   at least two lower sliding guides being provided on a top and a bottom with a plurality of third sliding bearings, such that the third sliding bearings on the top of the lower sliding guides bear against an upper inner surface of the lower slide and a lower inner surface of the inner slide, and the third sliding bearings on the bottom of the lower sliding guides bear against a lower inner surface of the lower slide and an lower outer surface of the inner slide, causing the lower slide and the inner slide to mutually slidably assemble to each other; and   a mounting plate for holding the mutually assembled upper, lower, and inner slides to a predetermined position.   
   
   
       4 . The drawer slide assembly as claimed in  claim 3 , wherein the upper slide is formed on the upper inner and lower inner surfaces with a plurality of axially extended first slide ways, and the inner slide is formed on the upper outer and upper inner surfaces with a plurality of axially extended second slide ways to correspond to the first sliding bearings. 
   
   
       5 . The drawer slide assembly as claimed in  claim 3 , wherein the inner slide is formed on the lower outer and lower inner surfaces with a plurality of axially extended third slide ways, and the lower slide is formed on the upper inner and lower inner surfaces with a plurality of axially extended fourth slide ways to correspond to the third sliding bearings. 
   
   
       6 . The drawer slide assembly as claimed in  claim 3 , wherein the lower sliding guides are provided on a lateral wall with a plurality of fourth sliding bearings, such that the fourth sliding bearings bear against a lateral inner surface of the lower slide and a lateral lower outer surface of the inner slide, causing the lower slide and the inner slide to mutually slidably assemble to each other. 
   
   
       7 . A drawer slide assembly, comprising:
 an upper slide being provided at one longitudinal side with an actuator;   an inner slide;   at least two upper sliding guides for causing the upper slide and the inner slide to mutually slidably assemble to each other;   a buffer unit being located in the inner slide and including a base and a buffer element; the buffer element having a piston rod provided at an outer end thereof, and the base being formed with a slide slot, at a terminal of which a retaining slot is provided; a linking member being mounted in the slide slot to connect to the piston rod via a link rod, and being controlled by the actuator on the upper slide to move into and out of the retaining slot on the base; and an elastic element being provided in the base with an end fixed to a point in the base and the other end connected to the linking member; and   a mounting plate for holding the mutually assembled upper and inner slides to a predetermined position.   
   
   
       8 . The drawer slide assembly as claimed in  claim 7 , further comprising a lower slide, and the lower slide and the inner slide being mutually slidably assembled to each other via at least two lower sliding guides. 
   
   
       9 . The drawer slide assembly as claimed in  claim 7 , wherein the upper sliding guides are provided on a top and a bottom with a plurality of first sliding bearings, and on a lateral wall with a plurality of second sliding bearings, such that the first sliding bearings on the top of the upper sliding guides bear against an upper inner surface of the upper slide and an upper outer surface of the inner slide, the first sliding bearings on the bottom of the upper sliding guides bear against a lower inner surface of the upper slide and an upper inner surface of the inner slide, and the second sliding bearings bear against a lateral inner surface of the upper slide and a lateral upper outer surface of the inner slide. 
   
   
       10 . The drawer slide assembly as claimed in  claim 8 , wherein the lower sliding guides are provided on a top and a bottom with a plurality of third sliding bearings, and on a lateral wall with a plurality of fourth sliding bearings, such that the third sliding bearings on the top of the lower sliding guides bear against an upper inner surface of the lower slide and a lower inner surface of the inner slide, the third sliding bearings on the bottom of the lower sliding guides bear against a lower inner surface of the lower slide and a lower outer surface of the inner slide, and the fourth sliding bearings bear against a lateral inner surface of the lower slide and a lateral lower outer surface of the inner slide.
