Description

SLIDING DOOR OPENING AND CLOSING DEVICE}

The present invention relates to an opening and closing device of a sliding door, and more particularly, by forming a rail inside the front door that opens and closes the front of a furniture or bathroom having a storage space so that the rear door is slid, the width of the door is reduced to visual The door can be easily installed by maximizing the finishing effect and assembling the front door and the rear door, and the quality of the door can be improved by stabilizing the sliding of the door by preventing the door from falling off by limiting the sliding of the door. It relates to an opening and closing device of a sliding door.

In general, various doors are installed in order to prevent objects from being seen from the outside by installing doors on furniture such as storage cabinets, bookcases, or cabinets that can store objects.

These doors can be divided into a sliding type and a sliding type according to the opening and closing method, and the opening and closing type is a method of opening and closing while the door rotates about the rotation axis by a hinge or hinge, and the sliding type is a method of opening and closing the width of the door along the rail.

The opening and closing type doors need the space corresponding to the width of the door as the door rotates, and the sliding type forms the rail as many as the number of doors, and the width of the door is formed by maintaining the distance between the doors to prevent each door interference. The household had to accept.

Patents 1087289 and 1151895 have been proposed to open and close the drawbacks of the sliding doors.

The opening and closing device of the sliding door is to open and close the sliding door to secure the storage space to the maximum and to open and close the door of the furniture with only one rail.

However, patent registration No. 1087289 of the opening and closing device of the sliding door as described above is a leveler that can adjust the position of the door because it is difficult to adjust the position of the door because the two doors are located in a straight line ( 70) to be formed more difficult to install, as well as the door is formed in a structure that is sliding to the front spaced apart when opening and closing the door there is a problem that the productivity is lowered and the assemblyability is lowered.

In addition, the opening and closing device of the sliding door of No. 1151895 can secure the storage space by opening and closing each door on one rail, but the rollers fixed to the doors are assembled in a state where they cross each other, making it difficult to install the door. Due to the complicated structure of the slider when opening and closing the productivity was lowered and there was a problem that the installation of the door is not easy.

The present invention has been made in view of the above-mentioned problems of the prior art, by forming a rail on the inside of the front door so that the rear door is slid from the inside of the front door to reduce the distance between the doors to slim the width of the door visual The purpose is to provide an opening and closing device of the sliding door that can maximize the aesthetic effect.

Another purpose is to assemble the front door and the rear door to limit the movement of the door so that the rail is prevented from falling and the sliding of the door is stable, so that the quality can be improved and it can be installed in the body in one process to improve the assembly. There is.

Still another object of the present invention is to reduce the width of the front door and the rear door, while forming a rail in the frame of the front door can simplify the structure to improve productivity.

In order to achieve the above object, the present invention provides a front door fixed to the front frame on all sides of the front panel to be installed on the front of the body having a storage space and a door portion formed of the rear door fixed to the rear frame on all sides of the rear panel, A first rail part extending horizontally to the rear of the upper and lower front frames of the door part and protruding a first rail into the horizontal piece, and a body on the rear surface of the first rail part on a first rail and a horizontal line; A second rail protruding from an upper side of the second rail and a bottom side of the body having a receiving rail having a length-shaped groove, and a second side of the second rail of the second rail, The first vertical roller is formed to slide at both ends of the end, and the first horizontal roller is formed at both ends of the rear end of the horizontal piece of the lower front frame so as to slide on the receiving rail. An inner end of the formed first roller part and the upper and lower rear frames in which the second vertical roller which is slid on the first rail of the first rail part so as to slide the rear door toward the front of the first roller part is embedded inside the front frame. And a second vertical roller formed at the outer end of the upper rear frame so as to slide on the second rail, and a second horizontal roller formed at the outer end of the lower rear frame so as to slide on the receiving rail. It provides an opening and closing device of the sliding door, characterized in that.

The body side plates of the door part are formed to protrude from the upper side and the lower side to provide an opening and closing device for a sliding door, characterized in that formed to perform the stopper function of the first roller part and the second roller part.

A bent stand is formed at the horizontal end of the first rail part, and both ends of the bent stand are fixed to each other, and a bearing is formed horizontally or vertically to the rear to rotatably form a first vertical roller or a first horizontal roller. Provided is an opening and closing device of a sliding door, characterized in that the first roller bracket is formed.

Provides an opening and closing device of the sliding door, characterized in that formed in the first rail end of the first rail portion to form a rail groove and the second vertical roller is inserted into the rail groove.

The second vertical roller, the third vertical roller, and the second horizontal roller of the second roller part are rotatably formed on the second roller bracket, and the second roller bracket is formed with a fastening hole to fasten the corner of the rear frame. It provides an opening and closing device of a sliding door characterized in that.

As described above, the present invention forms a rail inside the front door so that the rear door slides inside the front door, thereby slimming the width of the door, widening the storage space, and assembling the front door and the rear door in one step in the furniture. Since it can be installed, there is an effect of improving the assemblability to facilitate the installation.

In addition, while reducing the width of the front door and the rear door has the effect of improving the productivity by forming a rail in the frame of the front door to simplify the structure.
