Description

The invention relates to a turn-tilt fitting for windows, doors and the like according to the preamble of claim 1.

It is possible to turn the sashes by means of turn-tilt fittings Windows, doors and the like around a vertical axis swivel to tilt a horizontal axis and in the to lock the closed position on the respective frame. It is known in connection with such turn-tilt fittings Additional fittings to use it enable the respective wing in a so-called To keep the night ventilation position, i.e. in a position with the wing tilted around a horizontal axis is, but not that resulting from the turn-tilt fitting occupies maximum tilt-open position, but at a smaller tilt angle is held so that the Wing, especially for ventilation purposes, only in the form of a Gap is open. A disadvantage of the known solutions is not just the need for additional components and therefore also an additional assembly work, but also that the corresponding elements of a normal wing actuation require separate additional operation.

The object of the invention is therefore a turn-tilt fitting of the type specified in such a way that a safe determination in a simple and user-friendly way of the respective wing in a night ventilation position becomes.

This object is achieved according to the invention by the characteristics of the Claim 1.

Through these measures, the function of determining the Wing in a night ventilation position in the function of Turn-tilt fitting integrated and thus it is possible that the turn-tilt fitting not only between locking, turning and Tilt position is adjustable or switchable, but that as another possible position is the night ventilation position, the fitting between these positions in the usual way by means of the connecting rod gearbox Handle is actuated.

The locking device preferably comprises at least one on the Forend rail pivoted locking lever that over a control cam provided on the drive rod can be actuated and with the teeth or corrugations in locking engagement is feasible. Instead of a pinion connected to the support arm axle can also the support link axle itself by suitable design of the end part take over the function of the pinion.

By blocking or releasing the rotary motion of the support arm axle and thus the pivoting movement of the support arm it becomes possible in a particularly simple way to set a variable To achieve night ventilation position for the respective wing, being due to the blocking and release of the rotary motion the support arm axle an extremely compact arrangement is achievable.

The pivoted locking levers can be art a clamping scissor encompassing the pinion, whereby between the blocking lever legs facing away from the pinion a free stroke path which ensures the free rotation of the pinion for the control cam provided on the drive rod and a clamping stroke path is formed, in which the Control cam with the blocking lever legs spread Clamp pliers leg closes and thus locks the pinion.

Accordingly, the operating handle of the turn-tilt fitting in the position corresponding to the tilt position, for example brought vertically upward position, then the Wing in the usual way around its horizontal pivot axis be pivoted, but it is by the invention Integration of the night ventilation devices in the turn-tilt fitting is possible, the wing in the desired position between the closed position and the maximum tilt opening position determine by pulling the handle out of the Tilt switch position corresponding vertical position somewhat is moved in the direction of the swivel switch position. On slight pivoting of the handle in this direction and so that a corresponding displacement of the drive rod leads to block the support arm and thus to determine of the wing in a partial tilt position. A release this determination is made again simply by the fact that the operating handle is in the rocker switch position the wing is either in the full tilt position or can be transferred to the closed position.

Figure 1 shows a turn-tilt fitting in the area of a stay scissors for one wing, one in a wing groove to be fastened faceplate 1 on which a drive rod 2 is guided longitudinally. On the faceplate 1 is an extension arm 3 via a swivel-slide joint 5 stored, and this Ausstellenker 3 is on a pivot axis 6 connected to a support arm 4, which with the Ausstellenker 3 based on the faceplate 1 in the issued Condition of the exhibitor core 3 includes an obtuse angle and with its end facing away from the exhibitor handle 3 is mounted on the faceplate 1 via an axis 7. The Support arm axle 7 is non-rotatable with support arm 4 or rigidly connected and extending through a crank the faceplate 1 created space between Face plate 1 and drive rod 2. At the protruding end is the support arm axis 7 preferably as a toothed or corrugated pinion 9 formed or with such Pinion 9 rotatably connected.

Between the faceplate 1 and the support arm 4 is one Locking device 8 effective between the faceplate 1 and the drive rod 2 is arranged and depending on the position of the drive rod 2 releases the pinion 9 or blocked.

This locking device 8 includes - as this in particular Top view of Figure 2 shows - a first blocking lever 10, which has a bearing pin 12 on the faceplate 1 is mounted, and a second blocking lever 11, the via a bearing journal 13 also on the faceplate 1 is mounted so that a pair of two-armed levers 10, 11th is present, which on one side of the bearing pin 12, 13th the pinion 9 connected in a rotationally fixed manner to the support link axle 7 reach around with their clamp pliers legs 17, 18 and their a leg away from the pinion 9 between them a free stroke 14 and set a clamping stroke distance 15 in which a control cam 16 is movable, which on the drive rod 2nd is provided and for example from a corresponding Expression can exist, as shown in Figure 1.

The width of the free stroke section 14 corresponds approximately to the diameter of the control cam 16 so that this in the free stroke 14 movable without operating the blocking lever 10, 11 is.

The width of the clamping stroke section 15 is less than the diameter of the control cam 16 so that when the control cam 16 in the clamping stroke section 15 with appropriate adjustment the drive rod 2 penetrates, spreading the Leg of the two locking levers 10, 11 and thus one Closing the clamp leg 17 and 18 is what synonymous with blocking the pinion 9 and thus a determination of support arm 4 and exhibiting link 3 is.

Figure 3 shows the turn-tilt fitting according to Figure 1 in one Ventilation position.

The Ausstellenker 3 is over at a small tilt angle the support arm 4 determined because its axis 7 through the Locking device 8 is blocked and thus with the exhibiting link 3 coupled wings over the triangular combination of Exhibitor handlebar 3, support arm 4 and faceplate 1 stable and is held immovable.

The blocking of the support arm 4 via the pinion 9 is a consequence of the fact that the control cam 6 via the drive rod 2 was brought into the region of the clamping stroke section 15 and thus the clamp leg 17, 18 were closed.

FIG. 4 shows the turn-tilt fitting in the full tilt opening position, the control cam 16 via the drive rod 1 Move to the left out of the area of the clamping stroke section 15 was so that the clamp leg 17, 18th could open again and thus the wing from the night ventilation position has been released.

FIG. 5 shows the representation of the detail X on the one hand Figure 3 and on the other hand the representation of the detail Y from Figure 4.

The representation of the detail X corresponds to the blocking of the Pinion 9 through the clamp leg 17, 18, that is the detection of the turn-tilt fitting in a night ventilation position. Here, gears or corrugations engage on the clamp jaw legs 17, 18 in corresponding toothings or corrugations of the non-rotatable with the support arm axis 7 connected pinion 9 and thereby prevent each further rotation of this pinion 9 and thus the support arm axis 7, which is rigidly connected to the support arm 4.

The detail display Y shows the case of the freely rotatable Pinion 9, with the pliers legs 17, 18 either is not engaged or at least through these clamp pliers legs 17, 18 is not prevented from rotating. This is always the case if the one with the connecting rod 2 connected control cams 16 not in the region of the clamping stroke 15 is located and accordingly the wing tilted freely can be.

The locking device 8 described can be just like the Very space-saving design variants to be described realize and without affecting the others Functions of the turn-tilt fitting in the normal structure of a integrate such fittings.

The embodiment variant shown in FIG a type of clamp assembly for the locking device 8 used, but are in this embodiment instead of the pincer legs encompassing the pinion 9 on the corresponding lever arms of the blocking levers 10, 11 toothed or corrugated end faces 21, 22 formed, which are brought into contact with the pinion 9 in a blocking manner can. The pinion 9 in this case has one in view larger advantageously on the achievable holding forces Diameter that corresponds approximately to the faceplate width can.

The two blocking levers 10, 11 lie in their longitudinal extent are on both sides of the faceplate middle but with a corresponding approach to each other Half of the faceplate bearing journals 12, 13, these journals 12, 13 mutually at the same time a swivel movement limitation for the two in Blocking lever located in different levels of the storage area 10, 11 form. The drive rod side are on the Locking levers 10, 11 in the area of the toothed end faces 21, 22 approaches 19, 20 are provided, between which a the drive rod 2 provided expansion lug 25 in the full Enter the tilt position and the blocking lever 10, 11 defined can keep out of engagement with the pinion 9.

Figure 7 shows the turn-tilt fitting according to Figure 6 in one Ventilation position. The control cam is located here 16 in the region of the clamping stroke section 15, whereby the toothed end faces 21, 22 of the blocking levers 10, 11 be pressed against the pinion 9, which in the already explained Way a determination or blocking of the extension arm 3 results.

FIG. 8 shows the turn-tilt fitting in the tilt opening position, wherein the locking device 8 is ineffective because the control cam 16 is located outside the clamping stroke section 15 and the two locking levers 10, 11 via one on the Driving rod 2 provided expansion lug 25 out of engagement be held with the pinion 9. The spreading approach 25 in this case presses against the two approaches 19, 20 the locking levers 10, 11.

FIG. 9 shows a further embodiment variant of the invention, in the to operate the blocking lever 10, 11 on the Driving rod 2 in a downward cranked area special control link 24 is provided.

In particular, Figure 10 illustrates that on the faceplate 1 locking lever 10, 11 enclosing the pinion 9 Form of jaws with themselves in the direction of the drive rod 2 extending, in the area of the free ends of the jaws located actuation approaches 19, 20 movably mounted are, and that on a facing away from the pinion 9 End intended locking lever end part 23. The in the area the pinion 9 equipped with a toothing or corrugation Blocking levers 10, 11 are caused by the interaction their actuating approaches 19, 20 with a control link 24 reversed between a release and a blocking position. The control link 24 is this Design variant around a separate part, which is also available in the drawing is shown separately and with the drive rod 2 is preferably riveted. Reach into this control link 24 the actuating approaches 19, 20, and in the control link 24 is a free stroke path for these actuating approaches 19, 20 14 and a narrower clamping stroke distance in comparison 15 provided. In addition, the control link 24 an end, between the actuating lugs 19, 20th retractable expansion lug 25.

Figure 11 shows the embodiment of Figure 9 in one Night ventilation position, in which case the actuation approaches 19, 20 of the blocking lever 10, 11 in the area of narrow clamping stroke distance 15 of the control link 24 and so that the locking lever 10, 11 tensioned against the pinion 9 are and as a result thereof pinion 9 and support arm 4 against any movement will be blocked.

Figure 12 shows the turn-tilt fitting according to Figure 9 in the full tilt opening position, in which position a Free rotation of the pinion 9 is given because of the spreading approach 25 of the control link between the actuation approaches 19 and 20 of the blocking lever 10, 11 is retracted and this blocking lever 10, 11 apart so that no Engagement with the pinion 9 is given.

In the embodiment according to FIGS. 9 to 12, the Control link 24 as a separate, connectable to the drive rod 2 Part executed, but it is in the same way possible, the control link directly by appropriate Provide impressions in the drive rod 2 so that the use of a separate part is unnecessary and also none Crank of the drive rod in the area of the locking device 8 is required.

Figure 13 shows an embodiment in which the locking and the release of a diameter corresponding approximately the faceplate width pinion 9 over a lever wedge arrangement takes place. For this purpose, the pinion 9 a displaceably mounted clamping member 27 is provided adjacent, that can be operated via a two-armed adjusting lever 29 is. This lever 29 is on the faceplate 1 over a pivot pin 12 is pivotally mounted and in the area of its long lever arm 31 with a control link recess 32 provided in the provided on the drive rod 2 Control cam 16 engages. The lever 29 is due the curved course of the control link recess relative to the longitudinal axis of the drive rod 2 depending on the drive rod position is pivoted. This pivoting causes a wedge engagement between the short lever arm 30 of the actuating lever 29 and the clamping member 27 which between Guides 28 is slidable, an axial movement of the Clamping member 27, so that this clamping member 27 is either blocking engages with the pinion 9 or the pinion 9 releases for rotation.

By designing the control link recess, which in Figure 14 can be seen in plan view, can therefore be due to the resulting lever ratios a high pressing force for the clamping member 27 and thus a high holding force in the Night ventilation position can be achieved.

Figure 15 shows the turn-tilt fitting according to Figure 13 in one Ventilation position. The control cam 16 pivots the two-armed lever 29 in a counterclockwise direction and thus presses the clamping member via its short lever arm 30 27 against the pinion 9 and thus blocks support arms 4 and exhibiting handle 3 in the position selected here, it should be noted that in all embodiments the size of the night ventilation angle is freely selectable, because the blocking of the pinion 9 via the locking device 8 can be done at any tilt opening angle.

Figure 16 shows the turn-tilt fitting according to Figure 13 in the maximum tilt opening position, that is, in the ineffective Locking device 8. The short lever arm 30 is in this Position over the control link recess 32 and the control cam 16 compared to the night ventilation position Figure 15 has been pivoted clockwise, which is synonymous with the unblocking of the pinion 9 through the clamping member 27.

Figure 17 shows an embodiment variant, which differs from the Turn-tilt fitting according to Figures 13 to 16 differs in that that between the control lever 29 and the clamping member 27 a toothing 33 is provided instead of a wedge engagement is. This toothing 33, which preferably corresponding an arc around the bearing pin 12 is designed so that depending on the pivoting of the control lever 29 the clamping member 27 against the pinion 9 in the blocking position is pressed or take the release position can. The teeth of the are in the blocking position Teeth 33 in positive engagement while in the release position there is a game between these teeth that it enables the clamping member 27 to extend as far from the pinion 9 remove that this pinion 9 can turn freely. The The main advantage of this embodiment is that the directions of force application are defined and so that any deadlock tendencies are eliminated can.

All of the design variants described are characterized by simple and space-saving structure and characterized in that the required night ventilation position via the actuator stem actuation, that is, by means of the normal operating handle can be done for the turn-tilt fitting.
