Description

Interlocking device of sliding door {INTERLOCKING APPARATUS FOR SLIDING DOOR}

The present invention relates to an interlocking device for a sliding door provided with a rail-integrated frame, and more particularly, a roller and an auxiliary stopper are provided on the upper part of the door to move the door smoothly without shaking, and to move the first and third sliders to the second slider. It relates to an interlocking device for a sliding door that can be shortened and material costs can be reduced.

In general, when installing multiple doors in a sliding manner, the interlocking triple sliding door, which opens and closes one door so that the other door can also be opened and closed in the desired direction, has the advantage of being able to use the entrance wider than the existing two-door system For this reason, it has been widely used recently.

Details of the interlocking device of sliding doors installed in a plurality of doors in such a sliding manner are described in the following patent document, Korean Patent No. 10-1222841 (hereinafter referred to as 'Patent Document 1').

The patent document 1 is configured to open and close a plurality of dongs in a sliding manner while roller parts are respectively installed at the upper ends of a plurality of doors, and the roller parts are transported along a guide rail installed on the upper part of the door frame.

However, the roller part described in Patent Document 1 is provided in the form of a normal roller in which the outer surface in contact with the inner surface of the guide rail is made vertical and has a different diameter and a step is formed.

In this way, when the roller and the outer surface and the inner surface of the guide roller are in contact with the vertical surface, the manufacturing cost increases because it is difficult to process the groove for the roller to be inserted. There is a problem that acts as a factor that increases the labor cost due to the need.

To this end, Korean Patent Publication No. 10-1629501 (hereinafter referred to as 'Patent Document 2') discloses a guide rail; a first pivot roller provided in a conical shape and installed on the top of the first door; a support plate movably installed along the guide rail and constraining the first pivot roller; a pair of pulleys installed at both ends of the support plate; an interlocking wire connected to the pair of pulleys; a first interlocking member that is bound to the interlocking wire and protrudes toward the front of the first door to be transferred together with the interlocking wire; a second pivot roller provided in a conical shape and installed at an upper end of a second door disposed in front of the first door, being constrained by the first interlocking member and transported together with the first interlocking member; a second interlocking member which is bound to the interlocking wire and protrudes toward the rear surface of the first door to be transferred together with the interlocking wire; and a third pivot roller provided in a conical shape and installed on the upper end of the third door disposed on the rear surface of the first door, constrained by the second interlocking member and transported together with the second interlocking member. The second pivot roller and the third pivot roller have upper ends respectively penetrated through the first interlocking member and the second interlocking member and are recessed into the guide rail, and the guide rail is formed between the second pivot roller and the third pivot roller. There is described an interlocking device for multiple sliding doors, characterized in that inclined rail grooves in which contact surfaces contacting the inclined surfaces are formed are formed.

Such a conventional interlocking device can be easily assembled and installed even by a non-skilled person because it is easy to process the pivot roller and the hole into which the pivot roller is inserted, and the pivot roller and the hole are easy to assemble.

However, in the conventional interlocking device, since only one hole into which the pivot roller is inserted is formed, there is a problem that the position of the pivot cannot be selectively freely installed structurally.

In particular, in recent years, the width of the vertical frame of the door is made small in order to achieve slimness and light weight of the door. There is a problem in that it cannot be installed, and there is a problem in that it is not possible to pursue slimming and lightening of the door due to this.

In addition, in the prior art, since the groove of the closing member connected to the end of the interlocking member is assembled with the protrusion formed in the interlocking member, the protrusion easily falls out of the groove according to the continuous operation of the door, and the binding force is lowered.
