The present invention relates to a screen device including: a window frame comprising an upper frame, a lower frame, and right and left frames; a screen; and a frame enclosing the outer surface of the screen. The slide type engaged screen device comprises: multiple roller rails formed on the bottom of the upper frame of the window frame; a roller member moving by being inserted into the roller rail; a screen window combined to the lower end of the roller member; a separation preventing protrusion member formed on the lower end of the screen window; a guide member in which the separation preventing protrusion member is inserted to slide; and an engaged hanging member drawing the adjacent screen window by being connected to both sides of the screen window and the lower frame of the window frame in which the guide member is formed. The multiple screen windows can be opened and closed in an engaged type to efficiently block a wide area. The screen window is not easily open due to the separation prevention member and a locking device, so the screen device provides efficient crime prevention and insect resistance. Also, a metal net of high strength can be used for a material of the screen, and the screen device can prevent trespassing from the outside. |
