Embodiment Construction

[0020] Referring to FIGS. 4 to 9, there is shown a slide assembly in accordance with the invention for use with an extension table. At either front or rear side of the table, the slide assembly comprises a main slide member 30, an inner slide member 40, and an outer slide member 50 in which the main slide member 30 is overlaid with either one of the inner slide member 40 and outer slide member 50, each component is an independent element formed by molding, and they will be described in detailed below.

[0021] As shown in FIG. 4, the main slide member 30 comprises, at either upper or lower portion, a longitudinal wider groove 31 and a longitudinal narrower flange 32 adjacent thereto. The main slide member 30 further comprises an intermediate, elongated plate 33 integrally formed with the flanges 32. A roller assembly is provided at either end of the plate 33 and comprises a pulley wheel 34 and two opposite stop members 35 for securing the pulley wheel 34 to the plate 33 from both side...

Abstract

A pair of slide assemblies for use with an extension table are provided. The slide assembly comprises an inner slide member secured to a left leaf and including a first roller sub-assembly provided at an inner end, an outer slide member secured to a right leaf and including a second roller sub-assembly provided at an inner end, and a main slide member secured to a body of the table and including a roller assembly provided at either end and a belt run through the roller assemblies and the first and the second sub-assemblies. Pulling the outer slide member rightward will move the inner slide member to the left as the belt conveys around the roller assembly. The invention has the benefits of reducing sound produced during operation and enhanced structural strength.

Description

FIELD OF THE INVENTION [0001] The present invention relates to slides and more particularly to a slide assembly mounted in an extension table with improved characteristics such as increased structural strength and greatly reduced sound generated during pulling or retracting operation. BACKGROUND OF THE INVENTION [0002] A conventional extension table for increasing useable table area comprises left and right leaves and a slide assembly in the sides of either leaf. A user may pull either left or right leaf to pull both left and right leaves outwardly. For the slide assembly, it can be classified as one including two slide members or one including three slide members as described in detail below. Taiwanese Patent Publication No. 85,218,199 disclosed a slide assembly including two slide members mounted in either side of an extension table as shown in FIG. 1. As shown, at either side of the extension table a main slide member 1 comprises a central gear 2, left and right slide members 3 a...
