Structure of top and bottom symmetrical style slide rail}

The present invention relates to a structure of the upper and lower symmetrical slide rails installed on both sides of the lower side of the drawer to support the heavy load of the drawer and to be slidably by preventing rolling from side to side by an eccentric load. The upper and lower rails are symmetrically configured, and guide rails are installed therein, and ball bearings are installed between the upper and lower rails and the guide rails in a four-point hinge manner, respectively, and the upper and lower rails have an outer shape formed in eight shapes to form one side of both rails. It is to be able to slide by installing a ball bearing cross-supported by the bent end by bending the tip.

In general, the slide rail is installed on the lower or side of the drawer installed in general furniture, office furniture and home appliances to be configured to be able to slide in and out the drawer.

The drawer may be loaded with a variety of items, such as a relatively light weight, heavy goods, etc. If the drawer is not evenly stacked on the drawer, an eccentric load may occur, and may be tilted or lifted to one side. The slide rail installed in the drawer should be a smooth sliding for inlet and withdrawal even when a heavy load item is loaded and the drawer is tilted to one side even when an eccentric load occurs and the drawer's function is not lost. It requires a structure that does not.

The conventional slide rail is a sliding mechanism for a prior registered patent (Registration No .: 10-03181126) drawer as shown in FIG. 1, and its technical configuration is a tow rail 1 and an induction rail (upper and lower) respectively in the upper and lower portions of the inner rail 3; 2) install a three-point hinged ball bearings 4 between the inner rails 3 so that the induction rails 2 are installed at the side of the main body and the towing rails 1 are installed at the bottom of the drawer. It is configured to draw in and draw out drawers.

In the conventional slide rail, the towing rail 1 and the guide rail 2 are each provided with a set of three-point hinged ball bearings 4 on the inner rail 3 to smoothly support and slide under a constant high load. However, when the goods stored in the drawer generate an eccentric load, the slide rail is inclined or lifted to one side, so that stable pulling in and drawing out is impossible, and as a result of the above phenomenon, the clamping force between the drawer and the slide rail is loosened for a long time. Or detachment may occur, thereby increasing maintenance costs and reducing user convenience, and the inner rail 3 installed between the towing rail 1 and the guide rail 2 may be a mold-molded product. And there was a problem to increase the weight of the entire slide rail structure due to the high weight.
