Description

  The present invention relates to a drawer sliding mechanism that can be attached to furniture having a drawer to facilitate sliding of the drawer and can cushion a collision with a back plate when the drawer is closed.

  In recent furniture, a rail for furniture is attached to the sliding portion so that the drawer can be smoothly put in and out. In the furniture rail, a metal slide rail is accommodated in a metal guide rail, and a retainer in which a large number of ball bearings are arranged is installed between the guide rail and the slide rail. Therefore, the drawer slides very well, and when the drawer is pushed in vigorously, the drawer strikes the back plate of the furniture vigorously, and the reaction force causes the drawer to open slightly, damage the back plate, Something that had been put in order in the drawer collapsed.

  In view of such a problem, a retracting device has been proposed that prevents the pulling force of the drawer from being strongly hit against the back plate when the drawer is closed. This retracting device is a device in which a damper is installed inside a main body, and the momentum of drawing is buffered by the damper. (Patent Literatures 1 to 3) When the retracting device is attached to the side plate of the drawer, the operating piece for operating the retracting device is attached to the side wall of the furniture. Conversely, when the operating piece is attached to the drawer side plate, the retracting device is attached to the side wall of the furniture.

  By the way, the furniture is generally assembled by a knockdown method in which components of the furniture are manufactured at a factory and assembled by a dealer or a user. In other words, if the furniture is assembled in a knock-down manner, each component can be assembled, so a large amount of furniture can be transported at one time, so the transportation cost is cheaper, and even when stocking, it does not take up a large inventory space. Tesumu.

  Generally, in furniture, a guide rail is attached to a side wall of a furniture body, and a slide rail is attached to a drawer side plate. Conversely, a slide rail is attached to the furniture body, and a guide rail is sometimes attached to the drawer. When assembling furniture by the knockdown method, in any case, one of the drawer rails is first attached to the side wall of the furniture body, and then the other drawer rail is attached to the side plate of the drawer.

  When attaching the drawer rail to the furniture body using the knockdown method, before inserting the drawer into the furniture, first attach one of the drawer rails, for example, a slide rail to the side wall of the furniture, and then the other guide rail. Is attached to the drawer side plate. If one of the drawer rails is attached to the furniture main body in this way, the drawer does not get in the way, making it easy to install. Become. In the conventional drawer sliding mechanism, that is, the drawing device and the drawing rail are provided together, the drawing device is attached after the drawing rail is mounted and the installation position of the drawing device is measured. .

In general, when a retracting device is attached to furniture assembled by a knockdown method, it is attached above the guide rail apart from the guide rail. The reason is that the furniture after assembly cannot be attached in the vicinity of the guide rail because the guide rail is located below the drawer and the side plate of the drawer becomes in the way.
