Description

Structure of slide rails

The present invention relates to a structure of a slide rail installed on both sides of the lower side of the drawer to support the high load of the drawer and to be slidably prevented from being rolled from side to side by an eccentric load. The guide rail is installed inside the rail, but a ball bearing is installed between the upper rail and the guide rail by a four-point hinge method, and a ball bearing is installed between the lower rail and the guide rail by a three-point hinge method. Each guide bracket is installed so that the surface contact with the ball bearing in the center to slide.

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 various items, such as heavy items from relatively light weights depending on the use, and when not drawn evenly 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 smooth sliding for the inlet and withdrawal even when the heavy load item is loaded and the drawer is tilted to one side even if the eccentric load occurs and the drawer does not lose its function. The situation is demanding a rescue.

The conventional slide rail is a sliding mechanism for a prior registered patent (Registration No .: 10-03181126) drawer as shown in FIG. 1, and the technical configuration thereof is a tow rail 1 and an induction rail (upper and lower rail) respectively. 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 drawing and withdrawal is impossible. 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.

In this case, the fixing members 9 and 9 'are mounted at upper and lower portions of the moving member 6 at a predetermined distance so that the slide rail is inclined or lifted to one side so that stable pulling in and drawing out is impossible. The loosening force between the drawer and the slide rail is loosened or the detachment may occur, thereby increasing the maintenance cost and reducing the user's convenience, and the movable member (6) and the fixing member (9) (9 '). Balls (7) (7 ') installed between the two) is installed by the ball retainer, not only the assembly work is difficult, but also the processing process is complicated to reduce the convenience of work Ha had a problem.

Therefore, the present invention was created for the purpose of improving the above-mentioned conventional problems, and the ball bearings are installed on the upper rail and the lower rail by a four-point and three-point hinge method respectively installed on the guide rails, Each guide bracket is installed and slides by contacting the surface with a ball bearing in the center to facilitate assembly, minimize the weight of the assembly, as well as support the heavy load of the drawer mounted on the slide rail, as well as tilting or lifting the slide rail due to eccentric load. It is possible to provide a structure of a slide rail that allows the drawer to be slidably drawn in and out while stably sliding the drawer while reducing maintenance costs.

The present invention is installed between the upper rail of the square cap-type upper rail and the lower guide bracket is bonded to the inner side and the lower rail of the "L" type installed with the fixing bracket to the outside to face each other, but between the upper and lower rails The guide rail is installed in the upper and lower guides of the symmetrical type in the ball bearing is inserted between the upper guide and the upper rail and between the lower guide and the lower rail, respectively, and the ball bearing is installed between the guide brackets bonded to the inside of the upper and lower rails. It is done.

Therefore, in the present invention, the upper and lower rails and the guide rails are combined with ball bearings in a four- and three-point hinge manner, and ball bearings are installed with guide brackets in the center of the inner side of the upper and lower rails to efficiently support the high loads stored in the drawer and to provide eccentric loads. This prevents the drawer from tilting in the left and right directions, reduces maintenance costs caused by lower binding force between drawers and slide rails, and provides a solid drawer system. The weight of the rail is minimized and the assembly work is easy.
