And slide openings (21, 22, 23) are formed on both ends of the doors (61, 62, 63) so as to be smoothly slidable, corresponding to the slide passages (35) formed in the upper frame (30)

The front side of the first door 61 and the front side of the door 63 mounted on the outermost side of the door 63 are fixed to the interlocking belt 51 located at the upper end of the intermediate door 62, Respectively, so that the doors 61, 62 and 63 are connected to each other and opened and closed by the rotation of the belt;

The pivot holder 40 whose length is adjusted by the inner spring is fixed to both ends of the doors 61,62 and 63 so that the cap 42 of the pivot holder is inserted into the openings 21, 23 to the detachable groove 26 formed at the lower end of the door frame so as to easily attach and detach the doors 61, 62, 63 to the door frame;

A rotation bearing 43 is mounted on the vertical axis 41 of the pivot holder 40 inserted into both ends of the intermediate door 62 and coupled to the interlocking belt 51 to be rotated, 62, 63 are slidably opened and closed in association with each other; The present invention relates to a multi-slide door interlocking device, which facilitates door detachment and door sliding by using a pivot holder formed of a pivot holder.

The doors 61, 62 and 63 and the opening and closing ports 21, 22 and 23 are attached to each other by the pivot holder 40, the guide portion 31 is formed in the slide passage 35, The guide grooves 25 are formed in the openings 21, 22, and 23 to smoothly open and close the doors 62 and 63; .

Further, a rotation bearing 43 is mounted on the vertical axis 41 of the cloth holder, and a belt cover 44 of the interlocking belt 51 is formed on the outer surface thereof. .

The opening / closing ports 21, 22, and 23 may be formed separately so as to be positioned at both ends of the respective doors 61, 62, 63 corresponding to the doors or corresponding to the widths of the doors 61, 62, 63 So as to be long and integral; .

Further, the pivot holder (40) is provided with a door vibration preventing structure for preventing up-and-down vibration of the vertical axis (41) so as to prevent vertical vertical vibration of the door when the door is opened or closed. .

Hereinafter, a plurality of slide doors 100 according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 9. FIG.

As shown in Fig. 1, the present invention is intended to provide a slide door using a pivot holder when a plurality of slide doors 61, 62, 63 are mutually connected to slide and move in respective slide passages .

First, as shown in Figs. 2A and 2B, a passageway 35 is formed in the upper frame 30 of the door frame, through which the slide doors 61, 62 and 63 reciprocate.

The slide doors 21, 22 and 23 are fixedly mounted on the upper surfaces of the doors 1, 62 and 630, respectively, and one side of the openings 21, 22 and 23 is inserted into the respective passages 35 Combined and slide horizontally.

That is, the door 61 located on the inner side among the plurality of doors 61, 62 and 63 is fixed to the upper frame 30. When the outermost door 63 is opened and closed, (62) are also opened and closed together.

And slide openings (21, 22, 23) are mounted to slide smoothly in the slide passage 35 formed in the upper frame 30 so as to be slidably reciprocated in the passage 35 will be.

The doors 61, 62 and 63 are respectively coupled to the open / close ports 22, 22 and 23 in a detachable manner. The door and the door are required to be pivoted in the middle of the door, Is inserted and fixed to the upper surface of the doors 61, 62 and 63, and is detachably attached to the door frame integrally with the door.

To this end, a pivot holder 40 is fixedly mounted on both upper ends of the doors 61, 62 and 63 and the vertical axis 41 is fixed by an inner spring (not shown). When the pivot holder 40 is separated from the door frame, The inner spring is released and the length of the vertical axis 41 is increased. When the door is mounted on the door frame, the inner spring is pressed and the length of the vertical axis 41 is reduced, 62, 63 are mounted on the frame 30.

The passages 35 of the door frame are slidably fitted into the passageways 21 and 22 and the passageways 26 formed at the lower ends of the passageways 21 and 22, The door 61 is inserted into and detached from the door frame by inserting the door 42 into the door frame.

The principle of the sliding movement of the open / close ports 21, 22, and 23 is as follows.

In the door system 100 in which a plurality of doors 61, 62 and 63 are mounted on the door frame 30 to be opened and closed, the distance between the innermost first door 61 and the outermost door 63 And a rotary bearing 43 is mounted on a vertical axis 41 of the pivot holder 40 inserted into both ends of the middle door 62 The interlocking belt 51 is engaged and the interlocking belt 51 is rotated,

It is necessary to interconnect the interlocking belt 51 with the other doors 61 and 63 so that the intermediate door 62 and the other doors 61 and 62 are mutually connected to be slidably opened and closed, A belt fastener 50 is formed on one side of the door opening and closing ports 21 and 23 which are mounted on the upper end of the door 61 and the upper end of the door 63 located on the outermost side to fix one point of the interlocking belt 51 I will.

Accordingly, the doors 61, 62 and 63 are connected to each other by the rotation of the belt, thereby opening and closing the doors.

In detail, a rotary bearing 43 of the pivot holder 22 is attached to both ends of the opening / closing port 22 located in the middle door 62, which is rotated by one closed loop interlocking belt 51 .

When the door 23 of the outermost door 63 is pushed horizontally, the interlocking belt 51 fixed to the belt fixing port 50 is rotated, thereby causing the rotation bearing 43 to rotate, The opening / closing port 23 on the side of the bar and the opening / closing port 22 of the middle door 62 connected thereto are connected to each other to move horizontally, and the distance between them changes.

The opening and closing ports 21, 22 and 23 are mounted in the passageway 35 of the door frame so that the opening and closing ports 22 and 23 are slidably moved in the passageway 35. Specifically,

 The doors 61, 62 and 63 and the opening and closing ports 21, 22 and 23 are attached to each other by the pivot holder 40 fixedly mounted on the upper surface of the door and the guide portion 31 is formed in the slide passage 35 Guide grooves 25 are also formed in the open / close ports 21, 22, and 23 that slide in correspondence with each other to smoothly open / close the doors 62 and 63; .

A rotary bearing 43 is mounted on the vertical axis 41 of the cloth holder fixed to the upper ends of the upper surface of the middle door 62 to generate a rotary motion of the interlocking belt 51 by winding the interlocking belt 51, A belt cover 44 for protecting the interlocking belt 51 is formed on the outer surface of the belt 40 so as to prevent foreign substances such as dust from entering the belt or to be seen in the eyes.

As shown in FIGS. 3 to 6, the open / close ports 21, 22, and 23 may be formed separately at two ends of the corresponding doors 61, 62, and 63, (Not shown) for connecting the two openings 21, 22, and 23 spaced apart from each other by a predetermined width are fixed to fix the mutual distances.

5 and 10 show a structure for preventing vertical vibration of the door when the door is opened and closed. First, as shown in FIG. 5, a conventional fixing bolt 47 is used on the side surface of the pivot holder 40, The vertical axis 41 of the pivot holder is fixed to the pivot holder 40 and the pivot holder 40 when the door is opened and closed, (Not shown) of the door to prevent the door from being vertically vibrated by the elastic force of the inner spring (not shown).

10 shows a state in which the length of the vertical axis 41 is fixed by inserting a fastener 47 made of a plastic material cut in the vertical axis of the cloth holder 40 so that the length of the vertical axis is changed vertically by the inner spring when the door is opened and closed, Thereby preventing vertical vibration of the motor.

Therefore, the pivot holder 40 is provided with a door anti-vibration structure to prevent vertical vertical vibration of the door when the door is opened or closed; .
