So that the respective openings 20 are operatively connected to each other; .

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 characterized in that a plurality of slide doors 30 are connected to each other to slide on each slide passage, and a buffer function is added to the speed of the door when the slide door 30 is opened and closed, To increase the number of sliding doors.

First, as shown in Figs. 2A and 2B, a passageway 11 is formed in the upper chassis 10 of the door frame, through which the slide door 30 reciprocates.

A slide door 20 corresponding to each door is fixedly mounted on the upper surface of the door 30 and the upper side of the door 20 is coupled to each of the passages 11 to move horizontally.

That is, the door 30 located at the inner side of the plurality of doors 30 is fixed to the upper chassis 10, and when the door 30 located at the outer side is opened and closed, It is opened and closed.

3 shows a slide door 20 which is attached to the upper surface of the slide door 30 of the present invention and is horizontally moved in the passage 11 of the upper chassis 10, The opening and closing port 20 attached to the upper surface of the fixed door 30 is fixed in position and when the opening and closing port 20 attached to the door 30 opened and closed from the outside is moved, 20 are overlapped with each other on the same horizontal plane so that the distance between them is narrowed.

To be more specific, a rotary roller is attached to both ends of the opening / closing port 20 located at the intermediate portion, which is rotated by one closed-loop belt.

When the outer door 20 is pushed horizontally, the belt fixed to the fixing table 21 is moved, whereby the rotary roller rotates. As a result, the outer door 20 and the intermediate opening / (20) are connected to each other and horizontally moved, and the distance between them changes.

Since the door 20 is fixed to the upper surface of the corresponding door 30, when the door 30 is opened and closed, the door 30 of the intermediate portion connected to the door 30 is also opened and closed will be.

4 is a plan view of one side of the opening / closing port 20, which shows a contact surface of the slide opening / closing door 20 which is mutually attached to the upper surface of the slide door 30.

5 shows slide openings 20 each of which is smoothly reciprocated horizontally in the passage 11 of the upper chassis 10. The openings 20 are connected to the corresponding slide doors 30 And is fixedly attached to the base plate.

A locking protrusion 12 protrudes from one side surface of the inner passage 11 and a locking part 52 of the speed adjusting damper 50 is engaged with the locking protrusion 12, So that the hooking portion 52 is moved horizontally.

As shown in FIG. 6, the slide door 20, which is smoothly reciprocatingly engaged with each of the passages 11 of the upper chassis 10, is fully opened. A speed adjusting damper 50 is fixedly attached to a plane of the opening and closing port 20 located outside of the opening and closing port 20 to move together with the sliding movement of the opening and closing port 20, The function of buffering the speed control damper 50 is added to buffer the opening speed at the starting point where the fully closed door is opened and to control the closing speed at the time when the fully closing door is fully closed.

Further, since the two fixing tables 21 are fixed to the respective rotating belts, they move together with the opening / closing port 20 of the intermediate portion when the outside opening / closing port 20 moves horizontally.

7 shows a locking jaw 12 attached to the plane of the passage 11 of the upper chassis 10 and includes a speed adjusting damper 50 fixedly attached to the opening and closing port 20, The opening and closing port 20 is fixed to the upper surface of the slide door 30 so that the opening and closing port 20 is also horizontally reciprocated integrally with the door when the door 30 is opened and closed.

Figs. 8A and 9 show a progressing state in which the door 30 is opened, and Fig. 8B shows a state in which the door 30 is closed after the opening is finished.

 This is because when the door 30 is completely closed, the latching portion 52 of the speed adjusting damper 50 is caught by the latching jaw 12. When the door 30 is opened, the spring 55 is stretched, So that the door 30 is strongly opened and the door 30 is pulled so that the door 30 is opened slowly. As a result, even if the door is strongly opened, a slow opening effect is generated, thereby increasing the stability of the user.

When the door 30 is continuously opened, the engaging portion 58 is inserted into the engaging groove 53 formed at the downward direction, and the spring 55 is inserted into the engaging groove 53, And the damper rod 54 connected to the same horizontal portion as the engaging portion 52 is in a state of being extended to the maximum length.

When the door 30 is continuously opened in this state, the speed adjusting damper 50 is completely out of the position of the latching jaw 12 and the spring 55 and the damper rod 54 of the speed adjusting damper 50 And is fixed to the upper portion of the door 30 and horizontally moved together.

8C, the door 30 is in the closed state. When the door 30 is closed at a certain point, the latching jaw 12 presses the latching touch portion (not shown) of the speed adjusting damper 50 The engagement protrusion 58 is pulled out from the engagement groove 53 and the engagement protrusion 58 is released from the engagement protrusion 52. When the engagement protrusion 52 is inserted into the engagement groove 53, The damper rod 54 gradually enters the inside of the cylinder due to the elastic force of the spring 55.

When the damper rod 54 enters the inside of the cylinder, it functions as a buffer for reducing the closing speed of the door 30 by the damping liquid pressure contained in the cylinder. Therefore, even if the door 30 is strongly closed, the door frame is gradually closed at a certain point to completely close the door frame, so that an uncomfortable feeling such as shock or noise is not generated.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various changes and modifications may be made without departing from the scope of the appended claims.
