Abstract

The present invention relates to an interlocking device for a triple sliding door. The interlocking device includes: an upper rail fixedly installed on an upper portion of a door frame; a slide fitted into a first guide part of the upper rail, disposed movably along the first guide part, and having a through hole for fixedly coupling an intermediate door in one side thereof; a belt rotatably disposed between a pair of pulleys disposed on an upper portion of the slide; a first interlocking ball for moving the intermediate door and a front door relative to each other when the belt is moved; and a second interlocking ball for moving the intermediate door and a rear door relative to each other when the belt is moved. When each of the intermediate door, the front door, and the rear door are moved in a length direction of the upper rail, a looseness tolerance while each of the doors is moved along the upper rail may be minimized to stably maintain the movement of each of the doors and maximally prevent noise from occurring.

Description

Interlocking device of triple interlocking door

The present invention relates to a linkage of a triple interlocking door, and more particularly, to a linkage of a triple linkage door that can prevent the generation of noise by allowing the three doors to move stably and smoothly on the upper rail.

In general, when a plurality of doors are installed in a sliding manner, an interlocking triple sliding door that opens and closes one door to open and close another door in a desired direction has an advantage that a door can be used more widely than a conventional two door system. It is widely used in recent years.

As a technology of the triple interlocking door related to this, Korean Patent Registration No. 10-0724592, "opening and closing body interlocking device" has been proposed.

According to the prior art, the guide rail installed in the door interlock device is slid through the sliding groove formed by the first coupling part of the upper rail, which guides each time the door is opened and closed. There is a problem that noise occurs due to friction movement of the rail in the sliding groove.

In addition, the prior art is installed so that the engaging groove of each of the carrier body through the engaging piece formed in the longitudinal direction "L" shape on both sides of the substrate portion of the door interlock device and the door interlock device is installed in the second door body The transfer body is connected to the pivot shafts of the intermediate door body and the rear door body through the sliding hole to open and close the door body so that the engaging grooves of the respective carrier bodies slide through the engaging pieces in the door interlock device. When the sliding door is opened and closed repeatedly, frictional wear occurs, and the door linkage is slightly twisted in the middle door, the front door, and the rear door. When the furnace assembly is made, the coupling groove of the carrier is not slipped smoothly at the coupling piece. There is a problem that can generate noise together.

In addition, in the above prior art, since empty spaces are formed in the upper portion of the door body, outside wind flows through the upper end portion of the door body through these empty spaces, and thus, a problem in that windproof and soundproofing are not properly performed.

On the other hand, the interlock device of the sliding door of Patent No. 10-0880272 discloses a structure in which the guide rollers installed on the upper portions of the first, second and third doors are slidably opened and closed while being guided by the recesses of the upper rail.

However, the above prior art has a disadvantage in that it is difficult to attach or detach the sliding door to the door frame during the construction process or to be removed by the consumer, and the upper part is formed with an empty space to prevent wind and sound insulation.

In addition, the sliding sliding interlock of the Patent Publication No. 10-2003-64003 is mounted to slide on the lower surface of the door frame can be overlapping or unfolding the first interlocking door, the middle door and the second interlocking door; A pair of rotors fixed to the upper surface of the intermediate door to be rotatable; A rotating belt mounted to the rotating body; A pair of sleeves respectively formed upward from one side of the first interlocking door and the other side of the second interlocking door; And a pair of fasteners fixed to both sides of the rotating belt which rotate in opposite directions and fixed to the sleeve, respectively.

However, in the above prior art, it is necessary to fix the slab to the first interlocking door and the second interlocking door and to connect the fixture to the slab in order to interlock the first interlocking door, the middle door, and the second interlocking door. There is a problem in that the first interlocking door and the second interlocking door can not be used as it is, and the guide rollers fixed to the upper surface of the first interlocking door, the middle door and the second interlocking door on the three guide rails installed on the lower surface of the door frame, respectively. Since there is a structure that is moved there is a problem that excessive noise is generated in the process of moving each guide roller in the guide rail.

The present invention has been made to solve the above problems of the prior art, the purpose of which is to move each door on the upper rail when the middle door, the front door and the rear door is to move in the longitudinal direction of the upper rail, respectively. By minimizing the clearance gap, the interlock device of the triple interlocking door for preventing the generation of noise to the maximum while maintaining the movement of each door stably.

Another object of the present invention is to provide an interlocking device of a triple interlocking door to remove the empty space formed at the top of each door to prevent the wind from entering the top of each door to improve the effect of wind and sound insulation.

The interlocking device of the triple interlocking door according to the present invention includes an installation plate part fixedly installed on an upper part of the door frame, a first guide part formed in the longitudinal direction of the installation plate part at a lower center of the installation plate part, and the installation plate part. A second guide portion formed in the longitudinal direction of the mounting plate portion in parallel with the first guide portion on a lower front surface, and formed in the longitudinal direction of the installation plate portion in parallel with the first guide portion on the lower rear surface of the installation plate portion; An upper rail having a third guide part; A slider which is inserted into the first guide part of the upper rail and is formed to be movable along the first guide part, and on one side a slider having a through hole for fixing and coupling the middle door; A belt rotatably installed between a pair of pulleys installed on an upper portion of the slider; A front door fixing part for fixedly coupling a first belt fixing part fixedly coupled to one point of the belt, a front door formed adjacent to the first belt fixing part and movably installed in the front of the middle door; The intermediate door is provided when the belt is moved with a first guider installed above the front door fixing part and movably inserted into the second guide part of the upper rail to move along the second guide part. A first interlocking tool for allowing the front door to move relative to each other; And a rear door fixing part configured to securely couple a second belt fixing part fixedly coupled to one point of the belt, and a rear door formed adjacent to the second belt fixing part and movably installed at a rear side of the middle door. And a second guider installed on an upper side of the rear door fixing part and movably fitted to a third guide part of the upper rail to move along the third guide part. And a second interlocking port for allowing the door and the rear door to move relative to each other.

The interlock device of the triple interlocking door according to the present invention, when the middle door, the front door and the rear door are to move in the longitudinal direction of the upper rail, respectively, to minimize the clearance tolerance that each door moves on the upper rail Therefore, the noise can be prevented to the maximum while maintaining the movement of each door stably.

In addition, the interlock device of the triple interlocking door of the present invention, by removing the empty space formed on the upper end of each door can prevent the wind flows into the upper end of each door to improve the effect of wind and sound insulation. .
