The present invention relates to a reversible rocker window of the kind set forth in the preamble of claim 1.

A window of this kind is known from Norwegian Patent No. 107,278. Immediately upon opening such a window 5, this will act almost like a top hinged window, simply swinging out from below the upper pivots. These are freely downwardly movable in the vertical guide grooves of the sill sides, but the window is supported on both sides by said arm systems supporting the window at opposite 10 pivot or turning points located substantially in the horizontal center axis of the window. The geometry of the arm systems is such that the outward displacement of the window's central center axis of the window will cause it to steer it outwards approximately perpendicular to the frame plane, ie horizontally outwards, so that the supported axis of the window is forcibly controlled in the horizontal plane. Therefore, during the oscillation, the upper guide pins move downward along the grooves in the frame, and seen at a constant angular rate of the oscillation, this downward control of the upper oscillators will proceed at a steadily increasing speed until the window is oscillated to a horizontal outward-facing position .

The window can be swung further through this horizontally protruding position, simply pushing the previous upper edge of the window further down, whereby the turning points at the now 25 extended ends of the arm systems will move horizontally inward. again until the window is closed again or almost closed, now in a reverse position in which the normal outside of the window can be polished from the inside. For reversing the window, it is sufficient to push the now lower upper edge of the window upwards, as this will be controlled by the vertical guide grooves in the frame, while the arm systems will automatically swing outwards and then inwards as the window returns through the horizontal position. .

Precisely to facilitate the turning of the window, it is desirable that the arm systems support this approximately in the horizontal center axis, since the window is then in balance throughout the course of the turning, and it is further desirable that the arm systems be arranged to control the axis of rotation substantially 5. horizontally out and in, because the turning can then be carried out only by overcoming the friction occurring, but without additional forces resulting from a general substantial raising / lowering of the center of gravity of the window during the turning process.

10 It would be ideal to control the turning points along fixed, horizontal guide rails from the center of the frame sides, but for obvious reasons such a fixed projecting rail arrangement would be quite unsuitable in practice. In practice, it is precisely desirable that the guiding means used for the turning points are virtually invisible in the closed state of the window, and this is achieved by using the said arm systems, cf. the known construction is found to be designed in such a way that the swing arms included in the system can be unfolded in a supporting grid 20 and folded into a closed position, in which the swing arms all extend substantially vertically in the gap-shaped space between the window frames. exterior and interior of the frame, whereby the system may just be hidden in the closed position of the window.

25 Cf. In the known construction it has been found possible to design the geometry of the arm systems in such a way that arms can be used, which are pivotally connected, that they can be formed as one another, namely by using three movable pivot arms which can be folded into it. generally required vertical position in the closed position and may also fulfill the desire to effect a fairly straight, horizontal guide of the associated turning point of the window frame.

This is achieved in the known windows by using as a main element of the arm system a pivoting arm which, for approximation to the horizontal direction, gives a maximum flat curved oscillation of its free end, ie. a pivot arm hinged to the frame at the bottom of its base and extending upward as far as possible or necessary according to the geometry of the arm system in general. The system is therefore arranged to compensate for the flat-curved swing-out and down-swinging of the outer end of the long swing-arm, with the swing-arm at the top engaging with a knuckle or folding joint consisting of the two other swing-arms, the innermost being hinged to the frame immediately above over the upper end of the long pivot arm in its swung state, while the outer pivot arm extends downward from the upper end of the innermost pivot arm with a length of approx. twice as large as this, the outer pivot arm being extremely connected to the relevant turning point on the window and approximately at its center being pivotally connected to the outer end of the long pivot arm.

Said flat-curved oscillation of the long swing arm will thereby cause the outer swing arm of the folding joint to have its outer swing upwardly around the swing joint ice with the long swing arm, while the folding joint straightens out and the conditions are thus adjusted. , that the outer end of the outer swingarm, i.e. the horizontal center or turn axis of the window, which will move almost exactly rectilinear and horizontally outward.

25 In the horizontal intermediate position of the window during the turning, the folding joint is almost completely unfolded, and thus an arm system of a given size cannot be used for a window which is larger (higher) than the one for which the system is intended, while it could probably be used for the folding joint. 30 to a smaller window. However, the long swing arm of the arm system limits how much smaller the window can be, since the lower end of this swing arm is located near the lower end of the frame side. In practice, arm systems of a given size can therefore only be used for windows within a very limited height range, and it is therefore necessary to manufacture and stock a fairly large number of different sizes of the arm systems.

The invention has for its object to provide a window of the kind in question, the arm system of which is designed so that it can be used in one and the same size for windows within a large height variation area, which requires an automated window.

The invention is based on the recognition that it is possible to achieve the desired horizontal movement of the turning points of the window without the use of any pronounced flat curved swing of the long swing arm, ie. without this being particularly long, since this can also be achieved only by changing the dimensions of the arm system, ie. while maintaining an otherwise simply three-armed arm system.

In the light of the foregoing, the invention is characterized by the features of the characterizing part of claim 1. By comparing, in relation to the known construction, the point of attack of the second or lower pivot arm with the outer pivot arm closer to the breaking point of the folding link and by the fact that the lower pivot arm in the closed position extends beyond the frame hinge point of the inner pivot arm, it is achieved that the lower pivot arm can be significantly shortened and yet produce a horizontal equipping of the pivot points of the window. - the lower swing-25-arm outer will describe a distinctly curved path.

Precisely the use of a short lower swing arm means that it can be hinged to the frame side at a considerable distance from its lower end, and a high window arm system will therefore also be applicable to windows of considerably smaller sizes. However, for much smaller windows, it would be appropriate to produce a diminutive arm system, already because a large-size system would be unnecessarily expensive when, during the reversal of the window, one only needs to utilize a small portion of the horizontal equipment length for window turning points that the large system has capacity for. In practice, it is thus sufficient to produce and store quite a few different sizes of the arm systems, e.g. four times smaller sizes than before.

The invention also relates to a control arm system of the kind specified in the preamble of claim 3 and peculiar to the characterizing part of the claim, so that it can be used as a complete fitting in the manufacture of tilt windows according to the invention. The frame-mounted pivot arms have their pivot points so close to each other that they may advantageously be pivotally mounted on a common mounting plate which can be easily mounted on the frame side, whereby the arm system can be factory-prepared in such a way that it is only the mounting plate, which, as a single unit, must be mounted in an exact position on the casing side, and not the two swivel connections as independent units. Of course, a similar mounting plate could have been used in connection with the known construction, but partly this was not the case and, partly because of its required length, the mounting plate would mean a noticeable deterioration of the overall system. the use of such factory-made mounting.

25 plate of further importance in the invention in that the rectilinear horizontal guide movement of the turning axis of the window is conditioned by a fairly accurate location of the hinge points of the two frame mounted swing arms not only in relation to the window but also in relation to each other.

30 Precisely when using a fixed mounting plate as the basis for the frame-mounted swing arms, it is an advantageous additional possibility that cf. claim 4 can simply design the arm system with a safety lock which allows only slight oscillation of the arm system, unless the lock is manually released; a so-called child lock with this principle function is well known from other window types, but it will be seen that in the invention it can be established in particularly simple way by windows also of the kind considered, namely by designing suitable engagement parts directly between the mounting plate and one swing arm.

5 The invention will now be explained in more detail with reference to the drawing, in which: FIG. 1 is a plan view of a window according to the invention, viewed from the outside; FIG. 2 is a sectional view of the one shown in FIG. 1 is a sectional view, with the window shown in a ventilation position, fig. 3 is a section of the upper left corner of the window of FIG. 1, FIG. 4 is a perspective view of the upper left corner of the window frame of FIG. 1 and 3, and FIG. 5 is a sectional view similar to FIG. 2, with the window frame shown in a further, oscillated position.

In FIG. 1 is a view from the outside. The window consists of a frame 1 in which a window frame 2 is mounted by means of a control arm system according to the invention. To make room for the .20 control arm system, recesses 3 and 4. are formed in the two opposing vertical frame sides. On the inside of the vertical frame sides, guide grooves 5 (Fig. 2) are formed for pivot pins 6a connected to the frame 2.

The frame 2 is mounted on both sides in the frame 1 by means of a control arm system, which is described in the following only with reference to the left side of FIG. 1, with a quite similar control arm system arranged on the right side.

A recess 9 (Figs. 2 and 3) is attached to the recess 4 in the frame 1. An arm 14 is pivotally mounted on the plate 30 9 by means of a pivot pin 11 and is at its outer end at a pivot pin 16 connected to an arm 17 whose outer end is pivotally connected to the frame 2 by means of a pivot pin. 18. On the plate 9 a further arm 12 is pivotally mounted by a pivot pin 10, the outermost 5 end of which is pivotally connected to the arm 17 by means of an indicated pivot pin 15.

At the top of each corner a special pivot pin or guide shoe 6 is mounted on the frame. In the exemplary embodiment, this guide shoe is formed as a pivot arm 6, which is located in the frame 2, 10 which is most clearly shown in FIG. 4 is rotatable about a fixed shaft pin 6b and is extremely formed with a prominent pin portion 6a. By means of the shaft pin 6b, the pivot arm 6 is rotatably mounted in a recess 8 in the frame 2, in this case by means of a bracket 7, which is screwed into the frame 2.

In FIG. 2 is in: the window: showing a ventilation or vent position, that is, an almost closed position. In fully closed position, the swivel arm 6 is lower in the recess 8, but as shown in FIG. 2 and 5, it will pivot upwardly about the shaft pin 6b when the window is opened and optionally turned, the pin portion 6a being firmly embedded in the vertical guide groove 5 on the inside of the frame.

The arm 12 is provided with a rearwardly extending hook 13 intended to cooperate with a stop nose or drop bolt 20.

The drop bolt 20 is mounted on the plate 9 by means of two pins 25 which control the drop bolt provided with a corresponding elongated hole. Further, the drop bolt 20 is provided with a short arm 21 projecting from the plate 9 which serves as an actuating lever for releasing the hook 14 from the drop bolt 20.

30 When the window is opened by oscillation about the upper shaft pins 6b, cf. FIG. 2, the hook 13 will engage the catch and thus prevent further unintentional oscillation. However, further oscillation can take place after lifting the latch 149096 δ by the actuating arm 21. During the oscillation controlled by the pivot arm system 12,14,17, the outer pivot pin 18 will be moved approximately horizontally outward and the upper edge of the window frame will slide downwardly with the pin 6a sliding the vertical track 5 5. As the window is pivoted outwardly against the horizontal position, the pivot arm 6 will rotate with respect to the window, as it will remain horizontal as the pivot pin or, rather, the guide shoe 6a is formed as an elongate element in the track 5 .

10 When the window is pivoted to a horizontal position, the control arm system 12,14,17 will be maximally straightened and a further reversal can be effected by depressing the now inward-facing upper edge of the window. Hereby, the guide shoe 6a will travel down into the lower half of the groove 5, 15 and the guide arm system will begin to collapse. When the window is almost completely flipped, the hook 13 will engage snap-lock engagement with the latch 20, and in this position, the normally exterior of the window can be conveniently brushed from the inside. The window can then be pivoted back after triggering said snap-20 locking engagement.

The guide groove 5 is located near the inner end of the window picking rim of the frame 1, the groove having to pass behind the relatively wide mounting plate 9 of the control arm system. Thus, if the guide shoe 6a was a simple, fixed pivot pin 25 on the window, there would be no space in the fold for the window to be flipped, but this is precisely made possible by the shown design because the "pivot pin" has been replaced by a fixed pivot pin 6b. and a guide shoe 6a disposed on a swing arm 6 projecting from this pin.

30 The relatively large width of said mounting plate 9 is derived from the desire for the pivot pins 10 and 11 to be offset from one another in the horizontal direction, which is discussed further in the parallel patent application No. 2535/81. .
