Concealed slide module

Abstract

A concealed slide module is formed by installing an inner plate, at least one first ball plate, a middle plate, at least one second ball plate and an outer plate sequentially and installed between a bottom side of a drawer and a cupboard. The middle plate covers the exterior of the first ball plate and has an inner sidewall facing the inner plate and having a roof portion protruded horizontally outward from the top side of the middle plate, and a sliding section bent inwardly from a lower edge of the sidewall, and the sliding section is parallel to the platform, and a guide wheel is protruded from an outer sidewall at an end of the middle plate, and the middle plate slides with respect to the inner plate through the first ball plate.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No(s). 103204394 filed in Taiwan, R.O.C. on Mar. 14, 2014, the entire contents of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to the technical area of downwardly mounted slides for drawers, and more particularly to a concealed slide module with the design of a middle plate and having a roof portion and a guide wheel on two sidewalls to improve the stability and reliability.[0004]2. Description of the Related Art[0005]In general, a piece of furniture having a drawer such as a file cabinet, a cupboard and a desk usually comes with a pair of slides connected between the drawer and the furniture to facilitate users to push / pull the drawer to shut or open the drawer, and the slides are provided for carrying the load of the drawer and sliding the drawer. The c...

AI Technical Summary

Benefits of technology

The present invention provides a concealed slide module for improving the stability, reducing noises, and preventing drawer slides from falling out. The module has a roof portion disposed on a sidewall of a middle plate and a guide wheel installed on the other sidewall. The guide wheel guides an outer plate to move accordingly. In a preferred embodiment, the guide wheel has a protruding length equal to the distance between the middle plate and the outer plate and has a diameter equal to the distance between the axis of the guide wheel and the anti-loose portion. The bottom side of the roof portion is in a cambered shape for clamping a second ball therebetween. The outer sidewall of the bottom of the guide wheel has a section deviated to the outside, so that the first rollers are coupled to surfaces of the middle plate and the connecting section respectively. This design helps to minimize the gap produced after the assembling process to prevent producing vibrations or noises easily when the module performs an extending or contracting movement.

Problems solved by technology

However, the drawers may produce vibrations and noises in practical applications.

It is noteworthy that dimensions and symmetrical positions must be taken into consideration for manufacture the drawer slide with of the design of the dual roof portions 11, and thus having a very high level of difficulty of the manufacture and incurring a high manufacturing cost.

On the other hand, the dual wheel design comes with a too-large gap, and thus causing vibrations and noises easily.
