Windows, especially vertical sliding windows

The invention relates to a window, in particular with a vertically movable wing, the latter by means of at least two pairs of support arms is attached to a frame of a window, a door or the like

1.75

and each support arm is longitudinally displaceable and rotatable on the frame and pivotably mounted on the sash and is provided with at least one approximately Y- or T-shaped control cam, in which a control pin or the like attached to a longitudinally displaceable control member engages.
A window of this type has already been proposed
and it works in itself also in the
desired way. However, it has been shown that
It would be useful if this window or its support arms could be locked both in the closed position and in the parallel position. This is also the object of the present invention.

To solve this problem, a window of the type mentioned is proposed which, according to the invention, thereby it is characterized in that at least one upper and one lower support arm are additionally provided with a locking slot or the like are provided in which a locking pin or the like engages when the sash is closed » Appropriately, however, you will have a locking slot for a corresponding one on all support arms Provide a locking bolt. With the help of the aforementioned locking pins and locking slots, it is possible to open the wing

to lock as desired, both in the closed position and in the parallel position. If you have parallel opening leaves Initially only the upper support arms are pivoted, and the so-called ventilation position is reached with an inclined wing. This is also the case with the invention Training possible. It is easily conceivable when moving the sash from the closed position in the above-mentioned tilted position, first unlock the top and then e. "st on the lower support arms. This is according to the invention by a suitable choice of the Kippwinkelε Window burglar-proof even in this ventilation position. In a particularly preferred embodiment the invention is proposed in this context that with simultaneous displacement of the upper and lower locking pins, the upper ones are unlocked before the lower ones. The simultaneous shift the locking pin has the advantage over the separate one that the movements are positively coupled and so the desired sequence of unlocking occurs with certainty. The same applies, of course for the return of the wing from the ö / · exhibited in the closed position.

An advantageous variant of the invention in this context is characterized in that the bolt and the bull journal of each support arm are attached to a common control member. So if you move the control pin with, for example With the help of an adjusting mechanism, such as the crank handle of a window gear or the like, this has to be done also always a movement of the associated locking pin result. It is of particular advantage that the control and locking pin. one and the same wing spar are attached to a common control member and therefore all moved together or longitudinally displaced can be. In a further development of the invention, all control elements siad by means of a common one Drive, especially a three-position window gear manageable. The latter must be designed so that the common control elements of the left and right wing spar move in the same direction when actuated, i.e. at the same time hike below or above, assuming that the upper support arms as well as the lower each perform movements in the same direction.

According to another invention feature are in one

Fernster with for rotating and sliding storage in one Läagsschlitz the wing engaging support arm guide pin in the closed position of the wing, the control cam of each support army above and the bolt slot as well the guide pin or the like, below the support arm axis of rotation located. This means that, for example, when the sash is switched from closing to the Entlüftungs- uad finally the parallel parking position all support arms from bottom to top, so in Counterclockwise, be pivoted. Also achieved this results in a particularly low position of the guide pins, which is especially true for the lower support arms important is. This avoids that the profile edge when tilting the sash for cleaning runs out to the rear and leads to damage to the profiles.

Another feature of the invention is characterized in that that the control slot of the upper support arm © an approximately Y-shaped and that of the lower support arms have an approximately T-shaped shape, wherein in the In the closed position, one Y-arm in the direction of displacement of the control pin, the other perpendicular to this and the Y-center bar obliquely downwards, e.g. against the swivel

p.chse of the support arm, and that also in the closed position the T stands on the head, being Longitudinal web ia Verschiebererichtungg of the control pin runs, and that in the closed position all Pins are generally in their upper end position * When switching over, the latter move downwards. This design also contributes to the fact that the wing is locked in the Barallelabsteliage because the control curve runs in both cases in such a way that

a sucking force applied to the support arms, For example, wind pressure, none on the control pegs or at most exerts a very small restoring force, which rather clamps it.

The control slot of the lower Stützarrae is more appropriate Way as in the closed position upwardly open slot, that is formed with an open edge. Of Furthermore, the locking slot of the upper support arm is shorter than that in a very advantageous manner of the lower one, and moreover, in the closed position, both locking pins are located approximately at the upper end of the slot. When switching over leaves the upper locking pin its bolt slot in front of the lower one provided that both are locked simultaneously and equally

earlier unlocking than below. This gives you in the desired way a locking of the lower support arms in the tilt or ventilation position.

Another embodiment of the invention is characterized in that the lower support arms to each a corner drive for the assigned control element or an element connected to it are mounted, In particular, the support arm - guide pin is located approximately at the level of the horizontal control member. The advantage lies on both the production side and the assembly side. The deep position of the lower Support arm guide pin guaranteed in the interwoven Protection against damage to the profiles when moving the sash from the closing mechanism the opening position, especially if this pin is still below the guide of the lower horizontal control member part.

Another preferred embodiment of the invention is characterized in that the wing as Tiltable and hinged lower sash of a two-sash sliding window and designed

A wing (not shown) of a two-wing vertical sliding window has two upper opening devices 1 and two lower opening devices 2. The latter form with a corner drive 3 each one unity. With the help of this corner deflection, the movement of the horizontal control member 22 is on the vertical 20 transferred. The two upper opening devices are arranged at the same height as the left and right wing spar, as are the lower opening devices, which are assigned to the lower ends of these two vertical wing spars. The issuing devices exist essentially from a base plate 6 or 7? one support arm, each heavy around an axis 8 9 or 10 and one seal each - and one Control pin. The control pin of the lower opening device has the reference number 11, the one the upper one the reference number 1 °. In an analogous way, the locking pins with 13 for the lower or 14 designated for the upper opening device.

The upper support arms 10 are each equipped with a Y-shaped control slot 15. In the closed position (Fig. 5) of the wing points one Y-arm upwards and the other at right angles to it to the left.

The Y-middle bar is directed obliquely downwards to the right and in its extension is the pivot axis 8 of the protection arm 10,

The control slot 16 of the lower support arm 9 has the shape of a in the closed position of the wing on the Upside down T's. It is open at the top. The T-center bar runs when the sash is closed vertically upwards, that is, in the direction of displacement 17 of the control and locking bolts. The T-bar is in place perpendicular to this.

The two Riegei & chiitze have a straight line Course and are open at the edges when the wing is closed. The top latch slot 18 is shorter than the lower bolt slot 19 · This has the consequence that at the same time and at the same speed Downward movement of the locking bolts 13 and 14 of the upper is unlocked before the lower one, provided that both are at the beginning of the unlocking movement at the upper end of the slot lie. The two control pins 11 and 1 °, as well as the two locking pins 13 and 14 on each side attached to a push or control member 20, which via the ümlenkkette 21 of the corner drive 3 with the

Control member 20 in the downward direction of arrow 26, of course, this has a downward movement Latch and Stouer pin result in «This downward movement can be achieved, for example, by turning a crank handle of a window gear. In this Trap could, for example, also turn the Hand crank which can be seen from Fig. 3 and Fig. 6 assignment of the Stouer and bolt plucking can be achieved. The upper control pin 1? is from the vertical Y-arm 27 left and entered the Y center & slitz 28. Since the latter runs obliquely to the direction of movement of the control pin 12, a relative pivoting takes place the upper support tub 10 in the position shown in FIG. Strictly speaking, the Wing in the direction of arrow 29 tilts to the side, since the lower end of the arm over the guide pin 25 in a Vertical groove of the window frame, not shown, is held. This pivoting of the wing is However, only possible because at the same time the locking pin 14 also emerges from its locking slot 13 stepped out. The control pin 11 has meanwhile moved from the upper to the lower end position (Fig. 3). The same applies to the lower locking pin 13, but it should be noted that this

has not yet left its latch slot 19. As a result, there is a relative pivoting of the support arm 9 to the wing level still not possible.

With further downward movement of the control and locking pin does the upper control pin 1 leave? the Y-middle slot 28 to be inserted in the other in η Pig. 1 horizontally extending Y-arm 50 to enter. This has a further pivoting of the upper one Support arms 10 and the wing result. The upper locking pin 14 now has its lower end position reached in the guide slot 31 of the base plate 7. The same applies to the locking pin 13 » which has now reached its end position at the lower end of the guide slot 32 of the base plate 6. So is he of course also emerged from his locking slot 19 and this is now also possible the relative rotation of the lower support arms 9 with respect to the wing. Accordingly, the FIGS.

2 and 5 the closed position of the lower sash, FIGS.

3 and 6 show a tilted position of the lower wing and FIGS. 4 and 6 the parallel storage of the lower one Wing. In the tilt position, the lower one

Sash of the double-sash vertical sliding window, however tilted only so far that its upper edge in the event of forceful or unintentional pushing upwards of the lower wing runs against the upper wing. This provides an effective burglar protection, also in the ventilation position, FIGS. 3 and 6. Locked are, as already mentioned, also difc closed position according to FIGS. 2 and 5 as well as the Parallflabstellage according to FIGS. 4- and 7 · In the latter case, that is, when the one parked in parallel is forcibly pushed in Wing in the direction of arrow 34-, learns the upper control pin 12 no upward force and on the lower control pin 11 is after upward component of such a force (3 * 0 not sufficient to move the wing) the lower control slot 16 could easily be designed and arranged so that there also none upward component is produced when the wing is pressed inward in the direction of arrow 34 tries. If necessary, one can also change one more, especially by increasing the gear stroke take full advantage of longer control slot 16 in this regard.

In the embodiment example, the hand crank takes a 90 ° in the tilted position - and in the parallel

In the embodiment variant shown in FIG. 1, the lower support arms 9 are each arranged behind a cover plate 35. In addition, the aforementioned, not shown changeover gear for actuating the control members 20 in the three changeover positions (Cr, 90 ° and 180 °) is still locked by itself. This also contributes to the fact that no shifting of the gear rods or push members 20 can be achieved by shaking the window in the gap ventilation position, for example. In addition, the changeover handle can also be used as a sliding handle for the sliding window without having to fear an adjustment of the gear rods or control elements. If the lower sash can not only be parked in parallel, but can also be moved upwards, the fittings are attached so that the sash is moved inwards in the gap ventilation position as well as for parallel parking.
