AI Technical Summary
Existing sash windows with pressure frames require manual adjustment that is cumbersome and inefficient, particularly when opening and closing, due to the need for separate hand crank and double lever operations.
An adjusting device with a rotatable bearing plate connected to an angle lever, which integrates the hand crank and double lever functions, allowing simultaneous rotation and adjustment of the window frame, enhancing ease of operation.
Facilitates smooth and efficient opening and closing of sash windows by integrating the hand crank and double lever operations, reducing manual effort and improving operational efficiency.
Description
[0001] Actuating device for drop windows with pressure frame. Layman's invention relates to an actuating device for drop windows with pressure frame and characterizes by simply turning the hand crank of the adjusting device, the window frame is removed and the window is opened. or is closed by mounting the hand crank and a double lever used to adjust the window on a rotating plate, which is connected to an angle lever influencing the window frame in such a way that when the hand crank is moved, a rotation occurs first the bearing plate, and therefore the window is pulled off, and only then is the double lever turned and the window adjusted.
[0002] The drawing shows an embodiment.
[0003] Fig. i is a view with the window closed, Fig. 2 shows, on an enlarged scale, a vertical section next to the Actuating device. The drop window i hangs from a closed wire strand, the center of which engages the lever 2 at the top. The weight compensation takes place by cam disc 3 and tension spring q.
[0004] The window, when closed, is projected outwards and has a hook 13 on the lower frame. The pressure frame 14 The spring 12 pushes the window outwards. A hook ii is attached to the lower side of the pressure frame rail, which engages in the hook. 13 engages. Therefore, when the printing frame is pulled back inwards, it pulls the window off the outer track via hooks ii and 13. which frees it for downward movement. The pressure frame is removed by an angled lever 5, which is secured by bolts. 6 is connected to the bearing plate 7 in such a way that when this bearing plate is rotated about the fixed point 15, the angle lever 5 engages the pressure frame withdraws. A double lever 8 is mounted on the rotatable bearing plate 7, on whose A hand lever 9 is attached to the shaft. Two pull rods 10 extend from the double lever 8 to the lower end of the lever z, so that when the The hand lever 9, the double lever 8 and the lever a move. This moves the window up and down.
[0005] When the window is closed and the hand lever is moved, the double lever 8 will resist rotation, since the The window is moved and: cannot yet move downwards. The bearing plate 7 will now rotate around the fixed point 15, whereby The angle lever 5 is turned and the window is pulled off. Now the greater resistance of lever 2 ceases, and further rotation of the The hand lever 9 rotates the double lever 2, thus adjusting the window.
Claims
[0006] PATENT CLAIM: Actuating device for drop windows with pressure frame, characterized in that the adjustment is made exclusively by turning the The hand crank (9) of the adjusting device of the window pressure frame is removed and the window is opened or closed by pulling the hand crank (9) and a double lever (8) used to adjust the window is mounted on a rotatable plate (7), which is connected to the window pressure frame influencing angle lever (5) is connected in such a way that when the hand crank (9) is moved, first a rotation of the bearing plate (7) and therefore a The window is pulled off and only then is the double lever (8) turned and the window adjusted.
