BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawer suspension rail provided on furniture such as a desk and a cabinet, and more particularly, a drawer rail and an intermediate rail which constitute the suspension rail when the drawer is pulled out from furniture. The present invention relates to a drawer suspension rail in which the connecting portions are not exposed to the outside and the drawer can be pulled out without looseness.

[0002]

2. Description of the Related Art Conventionally, a drawer suspension rail of this type can be mounted in the main body rail and fixed to the inner surface of a side plate of a furniture body such as a cabinet. An intermediate rail provided with upper and lower surfaces on the upper and lower surfaces of a trochanter in contact with the upper and lower inner surfaces of the main body rail in a protruding state is slidably inserted, and a drawer rail projecting sideways on a drawer side surface is provided with an opening of the intermediate rail. And the upper and lower trochanters are slidably connected to each other, so that the body rail and the drawer rail are slidably connected via an intermediate rail.

However, in the case of the conventional suspension rail as described above, when the drawer is pulled out from the furniture main body, the intermediate rail slidably connected to the drawer rail is also pulled out from the main body rail at the same time. The drawer rails, the intermediate rails, and the connecting portions between the rails were exposed to the outside, which was not only unsightly, but also dangerous if the drawer rails and the intermediate rails were exposed.
In addition, since the draw-out rail is connected only to the intermediate rail drawn out from the main body rail, there is a problem that rattling in the left-right direction is likely to occur at the time of draw-out.

[0004]

SUMMARY OF THE INVENTION In view of the above points, the present invention draws out a drawer from a furniture body as a suspension rail which supports a drawer provided in a furniture body such as a cabinet or a desk so as to be freely drawn out from the furniture body. The drawer suspension, in which each of the rails and the connecting portions thereof constituting the suspension rail do not expose to the outside when exposed to the outside, is preferable in appearance and is safe, and the drawer can be drawn out from the furniture body without looseness. Rails will not be provided.

[0005]

In order to achieve the above object, a drawer suspension rail according to the present invention is slidably connected to a main body rail mounted on an inner surface of a furniture main body such as a cabinet. An intermediate rail, a drawer rail attached to the drawer side surface and slidably connected to the intermediate rail, and a drawer side surface provided to cover the drawer rail and the intermediate rail when the drawer is pulled out from the furniture body. And a rail cover provided at the rear end with a slider that protrudes rearward and that is formed to be able to bend laterally at an intermediate position between the protruding portions.

[0006]

With the drawer suspension rail according to the present invention as described above, as the drawer is pulled out from the furniture main body, the intermediate rail is also drawn forward from inside the main body rail, but is connected to the drawer rail and the drawer rail. The intermediate rail that is pulled out in this state is covered with a rail cover, so that the drawn-out rail and the intermediate rail do not appear to the outside. Further, since the slider is provided at the rear end of the rail cover, the rail cover does not come into direct contact with the furniture main body, and the slider comes into contact with the inner surface of the furniture main body, so that the drawer can be pulled out without rattling.

Further, since the slider is provided so as to protrude rearward from the rear end of the rail cover, the slider is maximally pulled out from the furniture main body until the rear end of the rail cover is located at the front end of the main body rail. When the drawer is pulled out, the rear part of the slider protruding rearward from the rear end of the rail cover is in the main body rail, and when the drawer is pushed into the furniture, the slider is guided so that the rear end of the rail cover becomes the front end of the main body rail. Collision with the rim is prevented, facilitating storage of the drawer in the furniture main body, and the slider covers the connection between the intermediate rail and the main body rail.

When the drawer is housed in the furniture main body as described above, the main body rail and the intermediate rail, and the rail cover and the drawer rail on the side surface of the drawer overlap between the inner surface of the furniture main body and the side surface of the drawer. The slider at the rear end of the rail cover is drawn out and protrudes rearward from the rear surface.However, since the slider is formed so that the middle part can be bent to the side, When the end abuts on the inner surface of the back plate of the furniture body, the slider is bent laterally at the intermediate position, and the protrusion width of the slider is reduced,
The dead space between the inner surface of the back plate and the back surface of the drawer in the furniture body can be reduced.
