In order to hold opened windows in an open position, use is made of a retaining device (16) which consists of a fixing plate (18) and a retaining arm (19). This retaining arm (19) can be pivoted and rotated about a vertical axis (23) and a horizontal axis (24) such that it can be brought into an operative position in which it surrounds the frame (20) of a window casement (2, 3), or it can be rotated and pivoted into a latching position in which it is arranged between the upper profile (22) of the window frame (10) and the underside (37) of window casements (2, 3) and is thus not visible at all. The fixing plate (18) is designed such that it can be clamped and secured in the upper profile (22) of the window frame (10), with the result that, in particular, a wobble-resistant held-open position of window casements (2, 3) can be achieved by the design of the retaining arm (19).

Description

DESCRIPTION

Device for keeping open windows open

The invention relates to a device for keeping opened windows, which consists of the defined in the building opening window frame and one or more sashes, which are pivotally connected to the vertical part or the horizontal part of the window frame, wherein the window sash of the window frame, a fixing plate forming the device associated with a holding arm, on which the holding arm is pivotally mounted and connected to the frame.

In this known device, the holding arm is provided with a plurality of notches, which can be inserted into corresponding projections on the window sash. In this way, it is possible to vary the opening degree of the sash corresponding to the recesses or notches. The disadvantage is that in the closed state of the sash of the support arm hangs on the fixer plate, usually protrudes quite far beyond the frame of the sash or the window frame and thus represents a hazard in several respects. Corresponding devices are the prior art

For example, if you are looking for Fensterarretierungen and similar keywords.

The invention is therefore based on the object to provide an open holder for windows, which is practically invisible and virtually locked in the active state, the window sash and is easy to handle in the active state.

The object is achieved according to the invention in that the fixing plate is formed clamped in the upper profile of the window frame and that of Holding arm about a vertical axis and a horizontal, in the direction of

Holding arms extending axis is pivotally mounted and rotatably mounted on the fixing plate.

This makes it possible for the first time to let the open holder disappear visually advantageous in the closed window or window sash. The holding arm, which is required to lock the window sash, can be rotated and pivoted and then rests on the upper profile of the window frame, wherein even in the closed state of the sash enough space for the fixing plate and the support arm is available. In modern windows are needed for tilting the window sash or

Hinges anyway housed on the upper profile or between the upper profile and the casement, so that these components in the

closed windows are not visible. This is no longer a risk of injury and at the same time the sash can be fixed in a predetermined position or in several others, which then again separate solutions are necessary, such as a sliding fixing plate or other solutions that will be discussed later.

The pivoting and rotation of the support arm in the fixing plate is thereby made possible in a particularly favorable manner and always remains smooth when the end of the support arm connected to the fixing plate is formed as a ball. This ball is mounted in corresponding holes, which will be explained in more detail later.

An always good rest of the support arm on the lower window frame, both in the working and in the rest position is possible because according to the invention, the support arm as a flat iron rod, the outer edge of the

Following window frame bent and the lower frame of the window sash unterfassend is formed. Again, this has the advantage that a secure fixation of the sash is secured, but at the same time this additional Component is virtually impossible to see and thus does not disturb the appearance. It is also advantageous that the window sash or the window sash not additional components must be attached, but it is sufficient that the corresponding bent executed flat iron bar under the lower frame of the sash or covers, so that it is always fixed and not in air blasts from the provided opening position can be pushed out.

An even more optimal fixation of the window sash is given by the fact that the holding arm, the width of the window sash and taking into account the window sash is partially carried out again bent up. Thus, the frame of the sash is literally clamped by the arm and can not be brought out of the open position even with air movements.

Sliding the lower frame of the sash onto the

Holding arm is made possible by the fact that the free end of the support arm after the upward bending has an oblique, the sliding over the window sash in the direction of the window frame deflection. So the lower frame slips up on this slope and the lower frame of the window sash then slips into the U-shaped bend of the support arm and is then held absolutely safe as already mentioned several times.

To the degree of opening or rather the opening angle of

Window sash, the invention provides that the holding arm,

is preferably formed telescopically in the ball-bearing horizontal portion. Of course it is also possible for example the

Enlarge the enclosure so that the window frame in this U-shaped opening of the flat iron bar can swing into the predetermined or desired position and set.

Another way to vary the opening angle of the window sash is the one in which the holding arm in the window wing unterfassenden Section has spaced apart, in recesses on the underside of the sash insertable, rod-shaped attachments. In such an embodiment, it is unnecessary to provide sliding over the window sash in the direction of window frame facilitating bends, because here the top of the flat iron rod seated essays in corresponding

Recesses or grooves are inserted or inserted on the underside of the window sash, in order then to fix the sash in the desired position.

Earlier it has been mentioned that the ball of the Flaltearms is fixed to the fixing plate, which is achieved according to an embodiment of the invention in that the end-side ball of the Flaltearms is clamped between an upper and a lower wing of the fixing plate. This can be particularly well realized when the fixing plate is made of plastic, which allows a limited mobility, so that the lower and the upper wing is pushed apart by the ball to be inserted slightly, and then effectively clamp the ball and thus set the Flaltearm to the fixing plate.

A displacement of the ball between the two wings is prevented by the fact that in the upper and lower wings of the fixing plate on the

Fixing point for the ball is provided a bore whose diameter is smaller, preferably 50% smaller than that of the ball. The ball and thus the entire Flaltearm are thus held and without their

Restrictability. By appropriate design of the hole slipping of the ball between the two wings can be prevented. The improved seat can be made larger by a diameter

Approach hole can be achieved at the fixing point.

Advantageously, the invention further provides that the Flaltearm can be arranged on one or the other side of the fixing plate or just Also, at the same time two such support arms are attached, so as to make the fixation of the opened casement particularly safe.

This is achieved in that the fixing plate is made a T forming, wherein the cross bar is formed as the ball holding, superimposed wings of the fixing plate. In this case, it is also possible to equip the stamp of the T and / or the transom with motion detectors, so that there is the possibility to make the unauthorized opening of the sash in a safe and simple manner in time.

The said ball of the support arm can be defined at both ends of the crossbar, ie at the end of the holding plate, since according to the invention, the wings at both outer ends have holes for the ball. These

Drill holes are therefore available in any case so that the user can choose which side he wants to attach the support arm or whether he can and wants to use two such support arms.

A secure resting of the fixing plate on the lower window frame is ensured because the underside of the fixing plate with the upper profile of the

Window frame is formed corresponding. In modern window frames here a groove is provided on the outside, which is also utilized to accommodate folding hinges or the like there, for example, to be able to open such a window can.

To facilitate the fixing of the fixing plate, the invention provides that the underside of the fixing plate can be pressed into the groove or

having an insertable angular approach. Even by the insertion of the approach in the groove, the fixing plate is fixed on or in the profile of the window frame, the fixing plate is favorably dimensioned so that it is supported with its rear part also at the rear part of the upper profile of the window frame. If the fixation of the fixing plate on the upper profile of the window frame to be further secured, this invention provides that in the middle of the foot of the T is provided in the groove insertable fixing plate fixing the window frame Flalteschraube. In addition to the angular approach, therefore, such a Flalteschraube can be introduced, which is similar to that of the hinged hinge and which can settle in the bottom of the groove.

To fully integrate this Flalteschraube in the fixing plate, the invention provides that the hole for the Flalteschraube a head of the

Flalteschraube receiving extension bore has, so this

Flalteschraube completely disappears in the profile of the fixing plate.

It is known that unfolded casements pose a threat to cats and similar animals. These animals try to get outside through the given slit of the open sash, strangulating and dying frequently. In order to avoid this, it has been found that it is expedient to make the window sash fixable in several positions or to design the holding device provided for this purpose accordingly. This is unnecessary if, as provided according to the invention, the fixing plate with holding arm and end-side ball is designed to be fixed to the upper horizontal part of the window frame. You can with the help of this

Holding device to bring the window sash in such a folding position, which is completely safe for animals, especially cats. Of course, too

Possibility, from the outset, the holding device in such a way that only this position of the sash can be realized during the opening process, so that the user does not have to check at all, in which position he has folded the window sash.

A particularly advantageous embodiment of the device provides that the connected to the fixing plate tail of the support arm has the vertical axis and an insertable into the fixing plate, rod-shaped end which is rotatably mounted in the fixing plate and represents the horizontal axis. It will be at omitted this embodiment of the joint to selectively specify two positions in which the support arm can be arranged. While a horizontal axis is formed in the fixing plate itself, the simple joint and thus the vertical axis is close to the housing, but arranged just outside, which is advantageous because this outside arranged joint or the vertical axis must be put into operation more frequently ,

In order to arrange the rod-shaped end and thus the horizontal axis securely within the fixing plate, it is provided that the rod-shaped end has a notch into which a movable of the fixing plate associated

Holding tongue is arranged inserted. Thus, the rod-shaped end is virtually fixed within the fixing plate and can only rotate about this horizontal axis. If you want to pull out the axis to arrange the holding arm from the other side and set there, the retaining tab must be released to pull the rod-shaped end of the fixing plate. If it is then inserted from the other end into the fixing plate, the holding arm can be fixed in the same way again via the retaining tongue.

Finally, there is the possibility, especially for old window frames to safely accommodate a fixing plate according to the invention and that in that the fixing plate is rectangular and formed on the profile or the groove supporting, the bottom of the fixing plate connectable with fixing screws with the horizontal base of the groove is. Thus, the fixing plate is adapted to the existing profile of the window frame and can be set there so that they can then fulfill their function fully, as will be explained with reference to the following drawings.

The invention is characterized in particular by the fact that a very elegant and easy to handle designed holding device for window sash is created. The holding device, consisting of fixing plate and arm, can be brought into an active position and a rest position where it completely disappears in the window frame, so no longer visible. This is possible because the fixing plate is placed on the upper profile of the window frame and fixed there in a longitudinal groove, preferably still supplemented by a retaining screw. The arm has, at the end, where it is releasably connected to the fixing plate, a ball so that it can be rotated and pivoted in two axes and then just rotated to a position and can be pivoted, where he between the upper profile of the window frame and the lower profile of the window sash is set, without this being visible from the outside. Further details and advantages of the subject invention will become apparent from the following description of the accompanying drawings, in which a preferred embodiment is shown with the necessary details and individual parts.

The two window sashes 2 and 3 can be rotated around the fittings 6, 7, so the window can be opened, the user normally uses the handle 9 thereby. With 8 the fall is designated, here the upper fall, d. H. So the transition between solid masonry and the frame parts of the window. 1

16 with a flattening device is referred to, which is easily visible here, slightly over the horizontal part 11 of the window frame 10 protruding.

Figure 2 shows a simple window 1, which is either swung open or unfolded. When unfolded part, here denoted by 14, a flattening device 16 is used, here the vertical part 12 of the

Window frame 10 is assigned. Not shown are the folding hinges 60, which are associated with the horizontal part 11 of the window frame 10.

The often used today profiles for both the

Window frames 10, as well as the sashes 2, 3, are shown in Figure 3 to illustrate how elegantly the flanging apparatus 16 can be accommodated between the two profiles of the window frame 10 and the sash 2 and the retaining arm 19 attached to the fixing plate 18 pivotally and rotatably mounted and the corresponding part of the frame 20, 21 of the

Window sash 2 may include. In this case, the 60th in FIG

referred to hinged hinge, which is already attached to the window sash 2 facing surface 15 today, here as a hinged hinge 60, which is effectively fixed via retaining screws 61, 62, wherein the

Retaining screw 61 engages in the groove 51, which also serves to fix the fixing plate 18. As already mentioned, FIG. 4 shows the upper part 59 of the vertical part 12 of the window frame 10, with the component according to the invention, ie the flanging device 16, being shown here as well as the folding hinge 60. These

Flattening device 16 can be used in the double glazing 17 shown in Figure 3, but also in a triple glazing or multiple glazing. The Flaltearm 19 is the end about a vertical axis 23 pivotally and at the same time still around a second axis as will be explained later, rotatable. It can be seen that the Flaltearm 19 is formed as a flat iron rod 27, so here rests with its edge on the upper part 59 of the horizontal member 11 in its rest position, while with the flat side, as shown later, in the active position is supported on the upper part 59.

In order to be able to attach flattening arms 19 to one or the other side of the fixing plate 18, bores 42, 43 are provided here at the fixing point 41, wherein it is also conceivable that such an arrangement of the flat arm 19 can take place simultaneously on both sides.

With regard to fixing point 41, FIG. 5 shows that here

Pivoting and rotation for the Flaltearm 19 is achieved because a vertical axis 23 and at the same time a horizontal axis 24 are given so as to pivot the Flaltearm 19 from one position to the other and rotate. It is also clear here that the flat side of the flat iron bar 27 is used when the flat arm 19 is pivoted out. The bore for fixing the fixing plate 18 on the upper part 59 of the

horizontal part 11 of the window frame 10 is designated 55. These

Bore 55 is provided with an extension bore 57, so that the head 56 of the Flalteschraube 54 can be embedded in the profile of the fixing plate 18.

Figure 6 shows a side view of the Flaltearms 19, wherein the narrow side of the flat iron rod 27 can be seen and wherein at the joined end 25 of the Holding arms 19 a ball 26 is arranged, via which a vertical axis 23 and a horizontal axis 24 are optimally represent.

The designated with 22 upper profile of the window frame 10 is again illustrated as shown in Figure 5, bordered by the flat iron bar 27 at the outer edge 28. The horizontal portion 32 of the support arm 19 may

be formed telescopically, so as to change the opening angle of the sash 2, 3.

FIG. 6 shows that between the bend 31 'and the upward bend 30 lies the horizontal part of the engaging subregion 33 of the holding arm 19, by means of which the profile of the window sash 2, 3, not shown here, can be securely enclosed, so that the window sash 2 rattles, 3 can not occur. In this U-shaped part of the support arm 19 is located in the active position of

Window sash 2, 3 safe in it.

At the free end 29 of the support arm 19, a turn is realized again, but so that a slope is formed so as to allow sliding over the sash 2, 3 in the support arm 19. When opened

Window sash 2, 3 can also be seen only this piece of oblique figure, because it protrudes over the window frame 10, which of course can be dispensed with, if with adverse effects or even dangers must be expected. This situation can be counteracted by including the end of this free end 29 with a rubber stopper or the like.

FIG. 7 shows a side view of a fixing plate 18 with a holding arm 19, wherein the ball 26 can be seen at the end of the holding arm 19. This ball 26 is between an upper wing 39 and a lower wing 30 of

Fixed fixing plate 18, in which case additionally, as already mentioned, holes 42, 43 are provided at the fixing point 41. In these holes 42, 43, the ball 26 engages when it reaches its correct position. On the other end, also formed here again as flat iron bar 27 holding arm 19 are rod-shaped projections 34, 35, 36 are provided, not shown in the here

Recesses 38 on the bottom 37 of the window sash 2, 3 can be engaged.

The underside 50 of a fixing plate 18 is shown in FIG. These

Bottom 50 is formed corresponding to the upper profile 22 of the window frame 10 or with this. The angular projection 52 is pressed into the groove 51 of the horizontal part 11 of the window frame 10 and then fixed on the retaining screw 54. The positioning and design of the required hole 55 has been explained earlier.

This component, d. H. the fixing plate 18 shows the shape of a T 45. The crossbar 46 of this T's 45 has the upper wings 39 and lower wings 40 shown in Figure 7, which are arranged at the outer end 48, 49 of the crossbar 46. The foot 47 of this T's 45 is relatively thick or wide and shows at the bottom of the retaining screw 54th

With reference to Figure 9 illustrates how a fixing plate 18 can be placed on the upper profile 22 of the window frame 10. For this purpose, the angular projection 52 is pressed into the groove 51, to then tighten the retaining screw 54, which is not shown here. At the opposite end of the T-shaped fixing plate 18, the wings 39, 40 are provided, with the outer edge of the large T 45, an application to a projection 63 of the upper profile 22 of the window frame 10 is possible. This is even without the

Retaining screw 54 sufficient fixing with the fixing plate 18 on the upper profile 22 of the window frame 10 is possible.

10 shows a rectangular shape of the fixing plate 18, due to this elongated design and the narrow

Long sides fully inserted into a groove 51 of the window frame and then via the fixing screws 66, 67 can be connected to the bottom 65. The Fixing screws 66, 67 are for this purpose introduced into the horizontal base 68 of the groove 51 and thus the entire fixing plate 18 is effectively determined.

Figures 11 and 12 show a further embodiment, wherein the two axes 23 and 24 are separated from each other. While further forward the ball has taken over the function of the two axes 23, 24, so far the two axes 23, 24 are separated, as the horizontal axis 24 is a rod-shaped end 25 "of the Flaltearms 19, in a corresponding bore or more Holes in the fixing plate 18 can be inserted. This horizontal axis 24 can be easily rotated with the help of the Flaltearms 19, so that the Flaltearm 19 is brought into the desired position.

The vertical axis 23, however, is a head outside the

housed actual fixing plate, which Figure 11 is easily removed. The Flaltearm 19 with its particular shape can be placed on this vertical axis 23 in the position in which it detects the profile of the sash and holds so effectively to maintain the predetermined opening degree of the sash.

It can be seen further in FIG. 11 and also in FIG. 12 that for fixing the rod-shaped end 25 "in the fixing plate 18, a notch is provided in which a retaining tongue 71 engages, which is assigned to the actual fixing plate 18. If the horizontal axis 24 and the rod-shaped end 25 'from the

Fixing plate 18 are pulled out to insert from the other side and set, the retaining tab 71 must be slightly raised, and it snaps easily when reinserting. That the vertical axis 23 performing tail 25 'can, as already explained, only a pivoting of the support arm 19 in a plane, so that intermediate positions can be safely excluded.

While FIG. 11 shows a top view of the fixing plate 18, FIG. 12 shows the bottom view, wherein retaining cams 73 can be seen here Inserting into existing profiles facilitates while the bore 74 the

There is possibility also about not screwing, but only

screwed screws to secure the position of the fixing plate 18. Here are the "ramparts" 75, 76 provided at the end of the fixing plate.

All the above features, including the drawings alone

taken, are considered alone and in combination as essential to the invention.
