This invention pertains to mechanisms for opening and closing sliding windows especially in homes and buildings. A sliding window comprises a pane which is installed in a sliding frame. The frame is sliding vertically or horizontally within a static outer frame which has two parallel guides that guide the sliding frame. There are three similar approaches for such a mechanism: a two cables mechanism, a single roller chain mechanism and a two roller chains mechanism. The two cable approach uses four pulleys and two flexible cables. The single roller chain approach employs two sprockets. The two roller chains approach uses four sprockets. The window can be operated manually or by using an electric motor. The window assembly includes two safety systems which protect persons from being caught by a closing window. The window assembly also includes a burglar alarm and does not require a latch for window locking. 1. A two cables mechanism for opening and closing a sliding window comprising: an outer frame , a sliding window , a lower two track pulley , an upper two track pulley , a lower single track pulley , an upper single track pulley , a left cable made of elastic and flexible material , a right cable made of elastic and flexible material , a turning handle , a gearbox , an electrical motor , a control unit , an upper limit switch , a lower limit switch , a safety system , a burglar alarm , a left spring , a lower spring and an upper spring;said sliding window comprising: a sliding frame, a pane, a lower left roller, an upper left roller, a lower right roller and an upper right roller; wherein said pane is made of transparent material; wherein said pane is framed in said sliding frame;wherein said sliding frame comprising: a lower left corner, an upper left corner, a lower right corner and an upper right corner; wherein said lower left roller is installed at said lower left corner, said upper left roller is installed at said upper left corner, said lower right roller is ...
