{Damper for Out Door of Furniture}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor damper for a furniture which provides a buffering effect when opening and closing an outdoor door installed between two side doors, So that the stopper and the locking member can be locked when the outdoor is closed even if a clearance is formed between the outdoor and the rail, and the outdoor door can be easily checked without detaching the outdoor door from the rail when checking the damper The present invention relates to an outdoor damper for a furniture.

BACKGROUND ART [0002] In general, a door of a furniture such as a wardrobe which is used at home is provided with a hinged door hinge provided inside the furniture body, a hinged opening / closing system for opening the door forward, A slide-type opening / closing method of opening and closing by a slide type using the installed roller is mainly used.

In recent years, a slide door of a sliding door type which is convenient to use, such as easy opening and closing, has been used more than a door of a sliding door type, which has a lot of space restriction at opening and closing.

The furniture in which such a slide door is used is structured such that a roller is installed on the door and a rail for guiding the left and right movement of the roller is installed on the furniture body.

Particularly, in the case of a built-in cabinet where an outdoor unit is installed between the two indoor units, the indoor unit and the outdoor unit are slidably installed on the rail. When the outdoor unit is caught by the stopper installed on the rail, There is a problem that the open / close range of the outdoor is narrow.

To this end, the Japanese Patent Application No. 10-1452688 discloses that when the temporary stopper is inserted into the fitting groove of the main switch, not only the outdoor is temporarily stopped but also buffered by the first driving unit or the second driving unit, The main switch is engaged with the first auxiliary switch or the second auxiliary switch without stopping at the position when the outdoor is slightly stuck on the stopper and the direction in which the main switch is moved beyond the pause stopper So that the outdoor open / close range of the outdoor can be extended.

However, conventionally, the first cylinder is connected to the first auxiliary switch, so that only the first cylinder is operated during the operation of the first auxiliary switch, the second cylinder is connected to the second auxiliary switch, Since only one of the first cylinder or the second cylinder of the outdoor unit is operated to open and close the outdoor when the two cylinders are operated, .

In addition, in the prior art, since the inserting portion of the temporary stopper is vertically installed and the inserting portion is inserted perpendicularly into the fitting groove in a state where the fitting groove of the main switch is horizontally installed, When the outdoor door is moved away from the groove in the opposite direction, the width of the contact groove of the tilted main switch and the contact portion of the stopper stop is very small, about 5 mm, There is a problem that the fitting groove of the main switch is not caught by the insertion portion of the stopper when the outdoor is closed so that the function of the damper is lost. That is, when the rail is deformed by long use, or when the furniture body is twisted due to temperature, humidity, self-load or the weight of the stored object, the stopper stopper is not caught by the main switch There is a problem that the damper function of the outdoor is lost.

Conventionally, since the damper is integrally fixed to the rear surface of the outdoor unit and the outdoor unit and the damper are integrally slidingly moved, when the damper is in trouble, the outdoor unit is completely separated from the rail There is a problem that it is not easy to separate the outdoor from the rail.
