AI Technical Summary
Existing sliding window mechanisms with scissor parallelograms face challenges in achieving complete closure without requiring additional space or intermediate pieces, as they either need the gear screw to be below the lowest window position or the window to be longer, which complicates installation and space utilization.
A rigid connection of the parallelogram to angle levers and rollers supports the window, allowing the angle levers to spread and provide additional lifting, enabling the window to clear the window opening edge without additional space, using a counter-rotating screw mechanism.
The solution allows for complete window closure within the available space by providing additional lifting motion, eliminating the need for extra space or intermediate pieces, thus optimizing installation and space utilization.
Description
Movement gear for sliding windows. The invention relates to a movement mechanism for sliding windows, in which the latter is lifted by means of a scissor parallelogram, the scissor arms of which are spread and stretched by means of a counter-rotating screw. The scissor parallelogram has the disadvantage in the known adjusting devices of the type mentioned that either the gear screw below the lowest position of the sunken window must be arranged, which is practically not feasible, or the actual window must be longer be as the window opening, so that it can also be completely closed when the scissor parallelogram is completely spread, or it must be between the lower edge of the window and the point of application of the scissors parallelogram, an intermediate piece is switched on, which the difference bridged between the altitude of this point of application when the scissors parallelogram is completely spread and the lower edge of the window opening. In this case, however, the scissors parallelogram would have to be longer by this intermediate piece, for which the space of the window chamber often cannot enough. According to the invention, the parallelogram is rigidly connected to the last parallelogram struts by means of angle levers and rollers or similar. Like. Connected to the window to be supported. This angle lever approach each other to an extended position when the parallelogram by means of opposite Screw is expanded and give the window an additional movement, through which it is lifted up to the parapet of the window opening. An embodiment is explained in the drawing in Fig. r in view and in Fig.2 in a longitudinal section. The sliding windowa is used in the embodiment in a frame; it can also be used without a frame and is supported by a rail b, which is connected to a scissors parallelogram d=, e, ei. This connection is made by means of rigid struts with the last parallelogram ch, d'= connected angle lever dl, d=, which carry the disc a on rollers e, c. The parallelogram d'=, e. d2, e is over the hinge point f also developed into a scissor parallelogram by the ancestor ei, ei. The ends of these scissor arms ei, e1 are attached to gear nuts g articulated, which are moved towards or away from one another by an opposing screw lt. This counter-rotating screw / t is in Angles i of the window sill bar k stored and gets its drive by means of a pair of helical gears Z and m from a crank n. Becomes the scissors parallelogram d=, e, e1 by turning the screw k appropriately to the extreme end position shown in dashed lines in Fig. 1 spread, the angle arms dl, dl are stretched due to their rigid connection with the arms d= of the scissors parallelogram. Through this stretching, pane a receives an additional lifting movement, through which it reaches over the upper edge of parapet k. The stare Angle arms dl, dl can be added to form a second parallelogram that carries the window in the middle.
