Description
- The present invention relates to a slide assembly and, more particularly, to a slide assembly for a drawer, a sliding platform, or the like.
-
FIG. 7 shows a conventional slide assembly for a drawer including a first slide 1', a second slide 2', and a ball bearing device 3' mounted between the first and second slides 1' and 2', so that the first slide 1' can slide in the second slide 2'. The first slide 1' includes a vertical wall 11' and upper and lower, first rails 12' extending horizontally from upper and lower ends of the vertical wall 11' in the same direction. The vertical wall 11' of the first slide 1' is fixed to a side board of a drawer 4'. Each of the upper and lower, first rails 12' includes a protrusion 121' for preventing disengagement of the ball bearing device 3' via rear end 13' of the first slide 1'. The second slide 2' includes a vertical wall 21' and upper and lower, second rails 22' extending horizontally from upper and lower ends of the vertical wall 21' in the same direction. A stop 211' is formed on each of two sides of a front end of the vertical wall 21' of the second slide 2' and extends toward the first slide 1' to prevent disengagement of the ball bearing device 3' via a front end 14' of the first slide 1'. A stop 212' is formed on a rear end of the vertical wall 21' of the second slide 2' and extends toward the first slide 1'. The vertical wall 21' of the second slide 2' is fixed to a side board of a cabinet 5'. When the drawer 4' is pushed back into the cabinet 5', the first slide 1' that moves together with the drawer 4' slides into the second slide 2'. At the same time, the ball bearing device 3' moves toward the rear end of the second slide 2'. The rear end 13' of the first slide 1' is stopped by the stops 212' to prevent disengagement of the ball bearing device 3' via a rear end 23' of the second slide 2'. When the drawer 4' is pulled outward from the cabinet 5', the front end 14' of the first slide 1' extends beyond a front end 24' of the second slide 2', and the front end of the ball bearing device 3' is stopped by the stop 211' and, thus, will not disengage from the front end 24' of the second slide 2'. Due to provision of the stop 212', the rear end 13' of the first slide 1' can not extend beyond the rear end 23' of the second slide 2'. However, the manufacturing costs are increased due to waste in material. Specifically, given that an overlapped length of the first and second slides 1' and 2' is 3 inches, in a case that the drawer 4' is to be pulled out of the cabinet 5' for 15 inches, each of the first and second slides 1' and 2' must be 18 inches (15 inches plus 3 inches). - Thus, a need exists for a slide assembly including first and second slides each of which is shorter than a pull-out distance of the slide assembly to save material and to reduce the manufacturing costs.
- The present invention solves this need and other problems in the field of costs reduction of slide assemblies by providing, in a preferred form, a slide assembly including a first slide, a second slide receiving the second slide, and a ball bearing device mounted between the first and second slides. The first slide includes a vertical wall and upper and lower, first rails extending horizontally from upper and lower ends of the vertical wall of the first slide in the same direction. Each of two ends of the vertical wall of the first slide includes an actuation piece extending toward the second slide. The second slide includes a vertical wall and upper and lower, second rails extending horizontally from upper and lower ends of the vertical wall of the second slide toward the first slide. A protrusion is formed on each of two ends of each of the upper and lower, second rails and extends toward the upper and lower, first rails of the first slide. The ball bearing device includes a body and a plurality of balls. The body includes a plurality of upper and lower holes rotatably receiving the plurality of balls. The body and the plurality of balls are mounted between the first and second slides to allow smooth sliding movement of the first slide in the second slide.
