Apparatus for automatically opening and closing window and doors

CHOI ONE BOK

The present invention relates to a device for automatically opening and closing a window which enables a window to be opened and closed by operating a switch in an easy manner without much effort and thus enables not only common people but also the infirm or people with reduced mobility to open and close the window by operating the switch without the help of others. The device for automatically opening and closing a window comprises: windows (17) (18) which are opened and closed by door rollers (21) (22) rolling on guide rails (23) (24) installed on a window frame (13) on lower portions of the windows (17) (18); control units (3) (4) which have an opening switch (3a) and a closing switch (4a); deceleration motors (5), (6) which are fixated to a front side protrusion (14) of the window frame (13), connected to the control units (3) (4), and rotated forward and backward; electric brakes (7) (8) which are embedded in the deceleration motors (5) (6), respectively; the windows (17) (18) which are opened and closed by an opening and closing means installed on rotation axes (9) (10) of the deceleration motors (5) (6) and on the window frame (13); first and second driving rollers (11) (12) which are installed on the rotation axis (9) (11) of the deceleration motors (5) (6), respectively, and are made of a material which is soft and has a high coefficient of friction for the surface; and one-side lower surface units (19) (20) of the windows (17) (18) which come in close contact with the first and second driving rollers (11) (12), respectively, and operate in cooperation with the first and the second driving rollers (11) (12). The first and second driving rollers (11) (12) are prevented from slipping by one among a crossing groove (34) with a predetermined gap and a predetermined depth which is formed to be integrated to the one-side lower surface units (19) (20) of the window (17) (18) to increase the coefficient of friction, an embossed part (35) which protrudes with a certain distance and a certain height, and a fine protrusion (36).
