Abstract: Disclosed is an insertion assembly for door and window frames which comprises a side frame and a transverse frame which is perpendicular to the side frame. An L-shape fixed member is provided at the outside of a connection portion of the side frame and the transverse frame, a side fastening bolt is provided to pass through a through hole at an upright portion of the fixed member and a through hole at the side frame to connect a side fastening panel, and a transverse fastening bolt is provided passing through a through hole at a transverse portion of the fixed member and a through hole at the transverse frame to connect a transverse panel.

Abstract: A trip device for a releasable connection between a sliding door/window and an invisible window screen comprises a screen side bar and a window sash frame at which a locking device is arranged for locking the side bar. In use, the window sash frame is pushed or pulled to translate to a window frame, and a controlling device is driven so that the locking device can be connected to the side bar. At this time, with moving the window sash, the window screen coiled in the hollow window frame can be drawn out so as to spread. When the window screen is not needed, the controlling device is driven, and the connection between the locking device and the side bar is released, then the window screen strip will automatically retract to the original state under the action of a screw torsion spring equipped at the reel.

Abstract: The present invention relates to an automatically sliding window without sash, comprising a frame body (1) having an upper slide groove and a lower slide groove formed therein, and an intelligent drive mechanism (3) being disposed at an upper portion of the frame body (1) and driving a window body to move horizontally. The window body includes a pane (2) and roller members (9) fixed to a lower edge portion of the pane (2), and the drive mechanism (3) is engaged to an upper edge portion of the pane (2). The area of the window according to the present invention allowing the sunlight to pass through is increased significantly compared to those windows in the art since each window body almost completely consists of glass. The closing and opening of the window body can be controlled more conveniently by utilizing an intelligently controlled transmission mechanism. The sealing of the window is improved since a bidirectional multiple sealing is applied between the groove and the pane or the panes.
