Description

Sliding door assembly {DOOR ASSEMBLY}

There have been various techniques for efficiently using a space by opening or closing a door including a window or the like and selecting a sliding movement method to facilitate opening and closing.

Such prior art is disclosed in Korean Patent Registration No. 10-1093545 entitled " Interlocking Device of Sliding Door "

The prior art includes a gear pulley having a first pinion and a second pinion both vertically and rotatably installed at both ends of the upper portion of the second door, An upper rail installed across the upper portion of the both gear pulleys and having an induction groove on which the induction rails can be guided, a first rails provided on the upper and lower rails, A rack which is installed at one side of the upper portion of the first door and is engaged with the first pinion to open and close the first door and the second door by interlocking with the third door, And an upper rail provided with an induction groove on the upper portion of which guide rails can be guided.

Also, according to the prior art, there is a registered utility model No. 20-0441738 entitled "

The above-mentioned prior art has a first roller member formed with an operating portion provided on one side of an indoor side window and two first guide grooves formed vertically in the rear of the operating portion, and two second guide grooves formed A second roller member horizontally extended in front of the operating portion and connected to one end of the outdoor side window and passing through one of the first guide grooves and one of the corresponding second guide grooves, A first wire connected to the other end of the outdoor side window and connected to the other of the first and second guide grooves and the second guide groove corresponding to the other of the first and second guide grooves, An opening / closing apparatus for an expensive sliding window formed of a second wire to be installed.

The related art relates to a sliding window or door, and relates to a technique of sliding all the doors in one direction in order to completely open or close a door that is paired.

However, there are many cases in which the sliding door system is used in which the sliding door system is opened or closed not in the sliding door system in which the sliding door is slid in the left and right direction according to the installation environment and circumstances of the door.

Such a conventional technique is disclosed in Japanese Patent Application Laid-Open No. 10-2015-0013410 entitled "

The above-mentioned prior art is an elevating and lowering apparatus included in a screen door opening / closing apparatus for vertically moving a first screen door and a second screen door. The elevating and lowering apparatus includes a column and a column, and is vertically movable along the column A first block and a second block in which the first screen door and the second screen door are coupled, respectively, and a second block and a second block, respectively, for moving the first block and the second block in the vertical direction, Wherein the first rotating pulley and the second rotating pulley are connected to the block so that the first rotating speed on the circumference of the first rotating pulley and the second rotating speed on the circumference of the second rotating pulley are different from each other, And a vertically opening and closing type screen door which is adapted to rotate the first rotary pulley and the second rotary pulley.

Also, in the prior art, there is a " elevator door opening / closing device of elevator opening and closing elevator of Registration No. 10-1533557 "

In the above-mentioned prior art, each of the guide rollers for guiding the pair of ascending / descending wires and the driving roller for receiving the power of the normal and reverse decelerating motors to move the ascending and descending wire are installed in the landing seal, A pair of reinforcing frames are fixed on the inner surface of the upper frame and a driving frame is fixed on the lower side of the reinforcing frame so that the guide rollers and the driving rollers are rotatable on one side of the driving frame And the gears of the driven roller provided on the driving roller and the gears of the driving shaft provided on the motor shaft are connected by a chain to transmit the power.
