Device for raising and lowering sliding windows

Description

[0001] Device for raising and lowering sliding windows. The invention relates to a device for raising and lowering sliding windows, in particular of vehicles such as closed automobiles and the like. This device is to be designed in such a way that it is as easy to handle as possible and has a simple design and few parts.

[0002] The essence of the invention consists in particular in that a swing arm, which is known per se and rotatable by means of a handle, for raising and lowering the window is arranged in such a way that, in addition to a rotational movement, it can also perform a movement perpendicular to the axis of the pivot pin on its pivot pin.

[0003] The arrangement can be such that the lateral movement of the swing arm in one direction is necessarily initiated by a rotational movement of this arm, such that with further rotation of the arm, the window is raised or lowered depending on the direction of rotation. The lateral movement of the swing arm in the other direction can be effected by a spring, which simultaneously counterbalances the weight of the window.

[0004] During the lateral movement under the influence of the spring, the swing arm can be locked against rotation by, for example, engaging with a toothed section in a stationary toothed ring. This locking can be further secured by a corresponding design of the handle hub and is released when the swing arm performs the lateral movement in the opposite direction due to rotation of the handle.

[0005] The drawing shows an embodiment of the invention, namely in Fig. i in front view of a car window, in Fig. 2 in section along line 2-2 of Fig. i, in Fig. 3 in section along line 3-3 of Fig. i; Figs. q and 5 show a detail in two different positions.

[0006] The side frames i of the car window are provided with guide rails 2 for the window pane 3. The support rail q of the pane 3 has a horizontal slot 5. A support plate 6 is attached to one of the window frames i by screws 7. This support plate has a semicircular recess 8, one edge of which has a row of teeth g. A pin io is attached to the plate 6 by a screw (Fig. 3). which lies at the center of the partial circle of teeth 9.

[0007] The arm ii for raising and lowering the window has a lateral pin 12 at its outer end, which moves in the slot 5 of the strip d. The inner end of arm ii has one or more teeth 13 that can engage with the teeth 9.

[0008] A handle 15 has a hub i4, which is rotatably mounted on the pin io and is shaped like a lifting thumb at its inner end 15'. This end 15' passes through an opening 16 of the arm ii, which is fitted with a flat wall (Figs. q and 5), against which a correspondingly flat side of the end 15' acts. The opening 16 is also of such a size that the arm ii at this end can perform not only a rotational movement, but also a linear movement parallel to the plane of the support plate 6. In other words, the arm can perform a rotational or oscillating movement and a bending movement perpendicular to the axis of the pin io.

[0009] A tension spring 17 is attached at one end to the outer end of the arm ii and at the other end to the support plate 6 (Figs. i and 2). This spring is intended, on the one hand, to hold the arm ii in the desired position or to compensate for the weight of the window, and on the other hand, to pull the arm ii inwards or to the right on the lifting thumb 15', whereby the teeth 13 engage with the teeth 9, and the flat side of the lifting thumb 15' rests against the corresponding flat wall of the opening 16, so that the arm ii is secured against rotation on the lifting thumb 15'.

[0010] To raise or lower the window, the handle 15 is pressed upwards or downwards, whereby the handle 15 with its hub 1q rotates on the pivot 10. When the handle is moved upwards, the arm 11 is first moved outwards, so that the teeth 13 disengage from the teeth 9 due to the action of the lifting thumb 15' in the opening 16. When the teeth are disengaged, the lifting thumb 15' assumes the position shown in Fig. 5. With further rotation, the handle 15 moves the arm 11 with it, and the window is moved by the pin 12 moving in the slot 5. When the pressure on the handle 15 ceases, the spring 17 returns the arm 11 to the locked position (Fig. q), so that the teeth 13 and 9 re-engage. which prevents the arm ii from rotating further until the handle 1.5 is rotated again.

[0011] PATrN T-ANsf rücüE: i. Device for raising and lowering sliding windows, characterized in that an arm (ii), rotatable by means of a handle and known per se, is arranged for raising and lowering the pane (3) such that, in addition to rotational movement, it can also perform movement in a plane perpendicular to the axis of the pivot on its pivot pin (io). Device according to claim 1, characterized in that a spring (i7) is arranged between the free end of the pivot arm (ii) and its support plate (6), which serves, on the one hand, to compensate for the weight of the window (3) and, on the other hand, to displace the arm (i) for raising and lowering the window in a direction perpendicular to the pivot pin (io). 3.Device according to claims 1 and 2, characterized in that the handle (i5) used for rotating the window adjusting lever (ii) as well as the swing arm (ii) itself are arranged on the pivot pin (io) by means of a hub (i4) and the hub is designed such that the swing arm can rotate and move transversely to the axis of the hub. Device according to claims 1 to 3, characterized in that the arm (ii) which is pivotably mounted on the support plate (6) is provided at its end facing the support plate with teeth (i3) which can engage with teeth (9) on the support plate (6) so that the arm (ii) can be secured against rotation and thus the window against displacement. 5. Device according to claims 3 and 1, characterized in that the hub (1.1) of the handle (i5) is equipped with. a lifting thumb (1j) and the arm (ii) is provided with a corresponding opening (i6), so that in a certain position of the lifting thumb (i5') in the opening (i6) the arm (i) is secured against rotation, while by rotating the handle (i5) the teeth (i3 and 9) are disengaged by means of the lifting thumb (i5').
