Description

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.

Also, as shown in FIG. 2, the prior application patent (application number: No. 10-2008-0073314) is a bottom-mounted slide, the technical configuration of the movable member 6 having the raceway portion 5, 5 'in the vertical direction The ball retainers 8 and 8 are provided with balls 7 and 7 'mounted on the upper and lower sides, and the fixing members 9 and 9' are installed on the outside thereof. It is installed on the side of the fixing member (9) was installed in the lower part of the drawer was configured to be able to draw in and draw out.

In the conventional slide rails, the fixing members 9 and 9 'are provided with four-point hinged ball retainers, respectively, so that the support and sliding can be smoothly performed at a certain high load, but the goods stored in the drawer may cause an eccentric load. 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 has been made for the purpose of improving the above-mentioned conventional problems to the outer shape of the upper rail and the lower rail to be installed on the guide rail to the eight-shape and install the ball bearings in a four-point hinge method, respectively, the upper and lower rails It is easy to assemble and minimize the weight of the assembly and the heavy load of the drawer that is mounted on the slide rail by bending the one end of the assembly and sliding the ball bearing of one of the ball bearings installed on the upper and lower rails to cross each other on the opposite surface. In addition to supporting and eliminating the inclination or lifting of the slide rail due to the eccentric load, it is possible to provide a structure of the slide rail which allows the drawer to be slidably drawn in and out while reducing the maintenance cost.

       The present invention bends the outer end to the upper rail having a bent end and the inner end is bent to install the lower rail facing each other with the fixing bracket is extended to the outside with the bent end, but the upper and lower guides of the symmetric type in the interior between the upper and lower rails The ball bearing is inserted between the upper guide and the upper rail and between the lower guide and the lower rail by inserting and installing the guide rail, and the bent end of the upper rail is installed on the upper outer side among the ball bearings installed between the lower guide and the lower rail. Supporting the ball bearing of the bent end of the lower rail is characterized in that for supporting the one ball bearing installed in the lower inner side of the ball bearing installed between the upper guide and the upper rail.

Therefore, the present invention is to combine the ball bearings in the four-point hinge method of the upper and lower rails and the guide rails symmetrical in the shape of an eight-shape and bend one end of the upper and lower rails to be bent at one end of the ball bearings installed on the upper and lower rails on the opposite side. By making the cross rails compact, the slide rail structure becomes compact, improving aesthetics, efficiently supporting high loads accumulated in the drawers, preventing tilting in the left and right directions of the drawers by eccentric loads, and reducing the binding force between the drawers and the slide rails. It can reduce the maintenance cost and provide a solid drawer system. The structure of the guide rail is changed to the forming method to improve the formability, minimize the weight of the slide rail, and facilitate the assembly work.
