[0001] Tilt lever for a sliding-tilt fitting

[0002] Description

[0003] The invention relates to a tilt stay for a sliding-tilt fitting of a sliding-tilt window or door with a frame-side fitting part and a sash-side fitting part, with a base plate of one fitting part and with a stay arm pivotably mounted in an elongated hole in the base plate arranged in the sliding direction and with a control arm pivotably mounted in the base plate and the stay arm, wherein the control arm has an open recess for a control slide movable by a displaceable drive rod.

[0004] DE 40 16 341 C1 discloses a fitting for a sliding or tilt-and-slide sash of windows, doors, or similar structures. It features a projection arm that can be forced open by means of an operating rod via a control arm. The projection arm extends from a rebate space between the frame and sash via a vertical leg. The mounting of the projection arm on the frame is thus visible when the window is closed.

[0005] DE 41 38 331 A1 discloses a fitting for a sash with forced tilt and parallel opening. It features a projection arm that interacts with an operating rod mounted on the sash. The projection arm extends out from the sash rebate, resulting in a very protruding fitting.

[0006] The invention is based on the problem of developing a tilting display of the type mentioned at the beginning in such a way that it is particularly compact and particularly easy to assemble.

[0007] This problem is solved according to the invention in that a holding cam of the control slide engages behind a rear engagement web of the extension arm in the position of the extension arm pivoted over the base plate, wherein a rear engagement recess on the side opposite the rear engagement web has a widening, so that the rear engagement recess is wider than the holding cam.

[0008] This design allows the components of the tilting stay to be connected one after the other in a mounting bracket. The control slide is preferably attached to the drive rod in the final step, for example, by riveting. The widened section in the extension arm makes the control slide particularly easy to access with riveting tools. Thanks to the invention, additional space for mounting assembly tools is no longer required. This makes the tilting stay particularly compact.

[0009] According to another advantageous development of the invention, the dimensions of the tilting stay are further reduced if the base plate has a section raised by the material thickness of the control arm, and the slotted hole for the extension arm is located in the raised section, and the control arm mounting is located in front of the raised section. This design allows the components of the tilting stay to be sandwiched one above the other. Therefore, all components can be concealed in the rebate between the frame and sash. By selecting the appropriate lengths for the control arm and the extension arm, the intended extension widths of the sash can be easily adjusted. This makes the tilting stay particularly compact.

[0010] According to another advantageous development of the invention, it contributes to further simplifying the assembly if a support body for the longitudinal guidance of the drive rod is arranged below a recess for the opposite fitting part in the position of the extension arm pivoted over the base plate.

[0011] According to another advantageous development of the invention, the creation of the raised section of the base plate is particularly simple in terms of construction if the base plate has two offsets for creating the raised section. Preferably, the raised section only has the total height of the control arm, so that the overall installation height is particularly small. The two offsets ensure the stability of the base plate and the raised section.

[0012] According to another advantageous development of the invention, the connection of the tilt stay to the parallel opening, sliding, or tilt fitting is simplified if the base plate is attached to a faceplate of the sash-side fitting and if the drive rod-operated control slide is slidably guided on the faceplate. The control slide is attached to a drive rod of the sash-side fitting.

[0013] According to another advantageous development of the invention, the tilting lever has a high degree of stability if the base plate is wider than the faceplate.

[0014] According to another advantageous development of the invention, a large leverage effect when driving the control arm can be easily ensured if the control slide protrudes laterally beyond the faceplate.

[0015] An uneven faceplate can cause the control slide to tip over. According to another advantageous embodiment of the invention, the control slide can withstand high supporting forces if the faceplate has a flat slideway to support a base of the control slide. This provides the control slide with the largest possible contact surface on the faceplate.

[0016] According to another advantageous embodiment of the invention, a particularly low-friction drive of the control arm can be achieved if the control slide has a control cam that penetrates the open recess of the control arm, wherein the recess and the control cam are complementarily rounded. The recess of the control arm thus forms a joint socket with the control cam, so that the control arm is driven by the control cam when the drive rod is driven. According to another advantageous embodiment of the invention, the control slide is structurally particularly simple if the control cam is arranged on a base fastened to the drive rod. The length of the base is the measure of the amount by which the control slide protrudes laterally beyond the faceplate.

[0017] According to another advantageous development of the invention, the construction of the tilting lever is further simplified if the base, control cam and holding cam of the control slide are manufactured in one piece.

[0018] According to another advantageous development of the invention, the manufacture of the control slide is particularly simple in terms of design if the retaining cam protrudes from the control cam. Preferably, the retaining cam has the same outer contour on one side as the control cam and can thus be arranged on its outer edge.

[0019] According to another advantageous development of the invention, the tilting lever is designed to be particularly compact if the control cam has a shoulder surface for supporting the engagement web.

[0020] According to another advantageous development of the invention, the control arm can be reliably prevented from projecting beyond the extension arm by arranging the control arm bearings in the extension arm offset from the control arm. This design also allows the control arm to be very short, which contributes to further material savings.

[0021] The invention permits numerous embodiments. To further clarify its basic principle, one of them is shown in the drawing and is described below. This shows in

[0022] Fig. 1 schematically shows a section of a sliding-tilt window with a sliding-tilt fitting and a tilting lever, Fig. 2 shows an enlarged perspective view of the tilting lever from Figure 1 in the tilting position,

[0023] Fig. 3 the tilting display from Figure 1 in a further perspective view,

[0024] Fig.4 greatly enlarged a control slide of the tilting lever from Figure 2,

[0025] Fig.5 the tilting lever from Figure 2 in a parallel storage position,

[0026] Fig.6 the tilting lever from figure 2 in a locked position.

[0027] Figure 1 shows a section of a slide-tilt window with a slide-tilt fitting 1, a tilt stay 2 and a stay scissor 3. The tilt stay 2 has a frame-side fitting part 4 and a sash-side fitting part 5, which are connected to each other via a stay arm 6. The stay scissor 3 also has a stay arm 7 for holding the sash. To simplify the drawing, only the connected fitting parts 4, 5 of the frame and sash are shown. The slide-tilt fitting 1 is connected to the tilt stay 2 via a drive rod 9 that is slidably guided on a faceplate 8. The drive rod 9 drives several locks 10 arranged around the circumference of the sash and the tilt stay 2.

[0028] Figure 2 shows the tilting stay 2 from Figure 1 in a tilted position of the sash. The stay arm 6 of the tilting stay 2 connects the sash-side fitting part 5 and the frame-side fitting part 4. A retaining pin 11 of the frame-side fitting part 4 is shown, which penetrates a recess 12, open on one side, at the free end of the stay arm 6. The retaining pin 11 and the recess 12 form a bearing for the free end of the stay arm 6 on the frame. If the extension arm 6 is pivoted over the faceplate 5, the recess 12 passes over a support body 37 connected to the faceplate 5. The tilting extension arm 2 has a base plate 13 fastened to the faceplate 8 with a raised section 14 with a bearing 15 of the extension arm 6 in a slot 16. The raised section 14 is separated by two offsets 17, 18 from a low section 19 lying flat on the faceplate 8.On the low section 19, a control arm 20 has a central bearing 21. The control arm 20 is connected at one end to the extension arm 6 via a bearing 23 and has an open recess 24 at the other end for a control cam 25 connected to the drive rod 9. When the drive rod 9 is moved longitudinally, the control cam 25 is moved along a flat slide track 38 of the faceplate 8 and the control arm 20 is thus pivoted, as explained in relation to Figures 5 and 6. The bearing 23 of the control arm 20 in the extension arm 6 is arranged offset from the center of the control arm 20, so that even in the tilted position shown, the control arm 20 does not project beyond the extension arm 6.

[0029] A retaining cam 26 projecting beyond the control arm 20 is arranged on the control cam 25. The extension arm 6 also has a rear engagement web 27 with an inlet ramp 28 for the retaining cam 26. The rear engagement web 27 defines a rear engagement recess 29 of the extension arm 6. The rear engagement recess 29 is wider than the retaining cam 26 due to a widening 36.

[0030] Figure 3 shows the tilting stay 2 from Figure 2 in another perspective view. The control cam 25 is part of a control slide 30. The control slide 30 projects laterally beyond the faceplate 8. The base plate 13 also projects laterally beyond the faceplate 8.

[0031] Figure 4 shows a greatly enlarged perspective view of the control slide 30. The control slide 30 has a base 31 with retaining pins 32 for riveting to the drive rod 9. The control cam 25 protrudes from the base 31 and has a rounded portion on its outside which is complementary to the rounded portion of the recess 24 of the control arm 20, which is open on one side. The retaining cam 26 protrudes from the control cam 25 and continues the rounded portion of the control cam 25 on one side. On the side facing away from the rounded portion, the retaining cam 26 has a straight contact surface 33 for sliding along the engagement web 27 of the extension arm 6. The engagement web 27 of the extension arm 6 is supported by a shoulder surface 34 in the positions shown in Figures 5 and 6. The control arm 20 rests in each position on a support surface 35 of the base 31.

[0032] Figure 5 shows the tilt stay 2 from Figure 2 after the drive rod 9 and thus the control slide 30 have been driven. The drive of the control slide 30 pivots the control arm 20 toward the faceplate 8 via the connection of the control cam 25 to the recess 24 open on one side. The extension arm 6 is located partially above the faceplate 8. The control cam 25 is still located in the recess 24 of the control arm 20, which is open on one side. This indicates a parallel storage position of the tilt stay 2. In this position, the sash is stored parallel to the frame and can be moved. The holding cam 26 is located in front of the inlet ramp 28 of the engagement web 27 of the extension arm 6.

[0033] Figure 6 shows the tilt stay 2 from Figure 2 in a locked position. Compared to the position in Figure 5, it can be seen that the control slide 20 has been moved further by the drive rod 9, so that the holding cam 26 is guided behind the engagement web 27 of the extension arm 6. The holding cam 26 has passed the inlet ramp 28 of the engagement web 27 and pulled the extension arm 6 further over the faceplate 8 compared to the position shown in Figure 5. The control slide 30 supports the engagement web 27 with the contact surface 33, so that the extension arm 6 is held in the position above the faceplate 9. In this position, the sash is locked in the frame. Furthermore, it can be seen in Figure 6 that the rear engagement recess 29 is wider than the holding cam 26 due to the spread 36, so that the control slide 30 is accessible with an assembly tool.The recess 12 of the extension arm 6 is located above the support body 37.
