An inward-opening type casement window having outward-opening pane and screen is provided. A primary screen is installed, via a first hinge, in a primary casement window frame so as to open inwardly. The primary screen is formed with a secondary frame. A secondary pane is installed, via a second hinge, in the secondary frame so as to open outwardly. A handle lock is installed between the primary screen and the primary casement window frame and between the secondary pane and the secondary frame. The handle lock is used to control opening and closing of the primary screen and the secondary pane. The pane can be swung out to facilitate ventilation, and the screen can prevent entry of insects and burglars. Moreover, the pane can be swung in together with the screen, thereby facilitating access, ventilation and cleansing.

The present invention is a preventive maintenance system and kit that can prolong the life of the regulators and motors. In performing repairs to automobile power window regulators and motors, it is often the case that the repair is required due to a breakdown of the lubricant. This breakdown can be due to several factors, such as age, temperature, dirt, and salts. The window regulators and motors, without appropriate lubrication, will fail and lead to more costly repairs. A kit has been developed to service the electric windows of an automobile without disassembling the door is presented. The kit provides for access to the door interior and for lubricating the interior parts. The kit and method is designed to lubricate the many window parts in order to extend their life and maintain functionality.

The invention concerns a mechanism (1) for a window (2), which is displaceably guided along grooves (4) and mounted pivotably 180 and 360 around a horizontal bearing spindle (5) and which comprises means (6 and 7, respectively) for the guiding and locking, respectively, of the window (2). According to the invention, a single handle (10) or another lever is situated or coupleable in the frame (8) or casement (9) of the window is connected with said locking means (7) for the window (2) and/or is connectable with said guiding means (6) for the window (2), whereby the locking and guiding, respectively, of the window is arranged to be provided by said single handle (10) or lever.
