Description

The invention relates to a window or door frame consisting of a metal-reinforced plastic hollow profile according to the preamble of claim 1.

In a special embodiment, such a window or door frame is known, which has a rebate air profile side consisting of two differently wide side rebate legs and a flat bottom lying between them, the striking plate comprising a striking plate plate which is to be screwed to the flat bottom of the fixed frame and is longer in the longitudinal direction of the frame, and one made of it angled, the narrower side rebate leg of the frame overlapping U-shaped striking plate leg with the striking plate recess located therein, and the locking bolt to be inserted therein is fastened to a push rod which is adjustably arranged in the associated casement frame.

It should be expressly pointed out that such special embodiments are known that for the implementation of the invention, however, only window or door frames according to the preamble of claim 1 should be assumed.

The special embodiments of such plastic hollow profile frames differ from other known striking plate fastenings purely externally by their angled from the fastening plate, the narrower side rebate leg of the profile frame U-shaped striking plate legs, which with its one-sided closing trough a more or less deep retraction of the for Wing bolt drive rod gear belonging locking bolt enables without special recesses must be provided in the narrower side rebate leg of the plastic fixed frame.

Such window or door frames also offer considerable stability if the striking plate has sufficient wall thickness. Meanwhile, the screw fastening seat on the plastic profile frame still leaves something to be desired, especially since the striking plate is kept comparatively narrow and is only connected to the metal-reinforced plastic frame via its fastening screws. Therefore, these striking plates are relatively easy to pry out when attempting to break open the window.

The invention is therefore based on the object of creating a plastic frame with a striking plate to be fastened thereon, in which the latter receives an even better fastening seat on the air gap profile side of the frame and in particular is even better protected against prying out.

This object is solved by the features of claim 1.

The invention results in the advantage that sufficient security against prying out of the striking plate can be achieved simply by engaging the striking plate in the parallel profile grooves.

For this purpose it is proposed that the parallel side edges of the striking plate engage with an overlap of at least 3 mm in the profile grooves.

A further advantage is that additional fastening of the striking plate by means of screw connections is possible without hindrance to the already sufficient stability by engaging the longitudinal edges of the striking plate in the profile grooves.

For the special embodiment of the known plastic hollow profile frame, the object is achieved in that the striking plate covers the flat bottom of the frame in its entire width and engages with its two longitudinal edges on the wider and narrower side fold legs of the frame existing profile projections on the inside.

In this embodiment, too, in addition to the conventional screw fastening seat of the striking plate on the frame, the form-fitting fastening seat of the striking plate on its longitudinal edges can also be realized with the corresponding profile projections, which are mutually present on the side fold legs of the frame, which leads overall to a substantial improvement in the fastening seat of the striking plate and the latter also protects much better against attempts at levering.

In principle, however, the striking plate with its striking plate could simply be inserted in the longitudinal direction of the profile frame over its flat bottom until it is screw-fastened in the correct place on the frame.

Although it is not important for the implementation of the invention to have existing side rebate legs, since it is only sufficient to provide profile grooves parallel to one another above the flat floor, it is advantageous for the fastening if the profile grooves sit on the inner walls of the side rebate legs in the case of window or door frames with side rebate legs.

This gives the advantage of a wide support for the striking plate. In particular, the striking plate is with one of its longitudinal edges in the area of the outside of the frame stored and in this way offers appropriate resistance at the attachment point of a lever tool for opening the closed window.

If the striking plate is provided with a plate thickness that is uniform over the entire plate surface, both profile grooves can be provided with the same groove widths.

Particular attention is paid to a further development in which the striking plate is a flat structure, the profile grooves being introduced directly above the flat bottom into the side rebate webs. In this development, the groove walls, which face the flat bottom, are flush with the flat bottom.

The same applies to the embodiment without side rebates.

A particular advantage is that the striking plate can also be screwed to the frame spar.

This creates a double-acting lever resistance. The combination of a screw connection, in particular a screw connection, into the metal reinforcement of the hollow profile, together with a striking plate plate lying on opposite longitudinal sides in the profile grooves, offers the greatest possible lever protection.

For the mounting of the striking plate, however, it is even more advantageous if the striking plate with the longitudinal edge of its striking plate plate facing away from its striking leg can be inserted transversely into the inner profile projection between the flat bottom and the so-called outer profiling groove located on the wider side rebating leg of the frame and with it other longitudinal edge of the plate between the inner profile projection sitting on the narrower side rebate leg is to be clipped into the so-called inner profile groove between the latter and the flat bottom of the frame. This allows the striking plate from clipped in place at the right place on the plastic hollow profile frame and, if necessary, screwed in afterwards. The clipping in of the striking plate has the advantage that it can no longer be held by hand due to its slight clipping on the frame, which is caused by the clipping in, and can therefore be more easily screw-fastened.

It is a further advantage if the outer profile groove has a greater depth than the inner profile groove and the distance between the two groove bottoms from one another is greater than the width of the striking plate, so that the latter are pushed a little deeper into the inner profile groove by being moved laterally can. This can ensure that the striking plate on the two longitudinal edges of its mounting plate is sufficiently far overlapped by the profile projections on the inside of the side rabbet legs, and in particular is also sufficiently positively overlapped on its clip edge facing the shorter side rabbet leg of the frame.

If the metal-reinforced plastic hollow profile, as is common, but without restricting the invention thereon, has double-walled side rebate legs, the outer profile groove is formed in the inner wall projection forming the inner wall of the wider side rebate leg, while the inner profile groove of that on the inner wall of the narrower one Side fold leg molded, top tapered inner profile projection is covered.

In its U-shaped angled striking plate arm, the striking plate advantageously has two symmetrical mutually lying, respectively open recesses. This means that the striking plate can be used for right or left hinging on the frame, in which it only needs to be turned around 1800. It advantageously consists of a T-shaped profiled sheet steel blank, in which the transverse web of the T-profile forms the striking plate and the central longitudinal web of the T-profile forms the striking plate leg, which is provided with the two locking recesses Striker plate leading connecting web is punched out of the striker plate blank in the center and angled at 90 ° to it.

According to a further feature of the invention, a guide plate can also be fastened to the push rod, which is guided in a longitudinally adjustable manner in a guide groove of the sash frame, in the region of its locking bolt, which covers the flat bottom of the sash frame containing the guide groove in its entire width and with its two longitudinal edges in both the wider and the undercuts on the inside of the narrower side rebate leg of the sash frame engage. In this case, the guide plate can lie flat on the push rod and be fastened by the locking bolt penetrating a bore contained in it, or be connected for entrainment. Preferably, the guide groove provided in the casement frame, as well as the push rod which is adjustably mounted in it, has a double-T profile, while the locking bolt is provided with an internally threaded bore into which a fastening screw penetrating the push rod engages. As a result, the push rod and the locking bolt seated on it are additionally supported on the sash frame and thereby effectively secured against tearing out in the event of an attempted break-in.

The window or door frame 1 shown in section in FIGS. 1 to 4 consists of a plastic hollow profile 3 reinforced by the inserted metal frame 2 on its rebate air section side facing the rebate air section B, two differently wide, each double-walled side fold legs 4 and 5 and a flat bottom 6 lying between them. In the inner wall of the wider side fold leg 4 forming an inner profile projection 4 'there is a profile groove 7 in the extension of the flat bottom 6 molded, which is referred to below as the outer profile groove. Likewise, there is a so-called inner profile groove 8, which is surrounded by the inner wall 5 ″ of the narrower side fold leg 5 and is covered by the inner profile projection 5 ′ that is tapered on the top side and is seated on the inner wall 5 ″ of the narrower side fold leg 5. The outer profile groove 7 has a greater depth than the inner profile groove 8. The greater depth of the outer profile groove 7 offers the striking plate greater coverage on the window opening side and thus a better hold against prying open.

The distance "c" between the two bottoms of the profile grooves 7, 8 is greater or at most equal to the width "b" of the striking plate 12, which will be discussed in more detail below.

The striking plate 10 to be fastened on the plastic hollow profile frame 1 described above is of the nature shown in FIGS. 5 and 6.

It has a striking plate plate 12, which is provided with screw fastening holes 11 and 11 'and which is longer in the longitudinal direction of the profile frame, and a striking plate leg 13 which is angled therefrom and which in the e.g. in Figure 4 mounting position on the frame 1 whose narrower side fold leg 5 engages in a U-shape. The free leg of the "U" lies flush on the top of the side fold leg 5 and is held against it by means of the fastening screw 18.

In this striking plate leg 13, which is angled in a U-shape, two locking recesses 15, 15 ', which are symmetrical to one another and are respectively open to the outside, are provided for the locking bolt 22, which is arranged on the associated sash frame, with respect to the center line 14 of the striking plate 10 (see Fig. 7). Another screw fastening hole 11 'is provided in the locking leg 13, namely on the center line 14 slightly above the two locking recesses 15, 15'.

5 and 6 also show that the striking plate 10 is made from a T-shaped profiled sheet steel blank, in which the transverse web of the T-profile, the striking plate 12 and the central longitudinal web of the T-profile with the two closing recesses 15, 15 'Provides striking plate leg 13, the connecting web 13' leading to the striking plate plate 12 'is punched out of the striking plate plate blank through the punch cuts 16 shown in FIG. 6 and angled by 900 to the plate 12.

The striking plate 12 has a width b which is greater than the distance a (for example 3 mm) between the inner profile projections 4 ', 5' of the frame 1, but is somewhat smaller than that between the bottoms of the outer profile groove 7 and the inner profile groove 8 existing distance c is. This ensures that the striking plate 10 in its final mounting position shown in Figure 4 on the frame 1 with the two longitudinal edges 12 ', 12' 'of a mounting plate 12 engages enough behind the inner profile projections 4' and 5 'on the profile frame, so that already insofar as there is a good fastening fit between the striking plate 12 and the rebate air profile side of the frame 1. By means of the fastening screws 17, 18 to be inserted into the fastening holes 11 and 11 'of the striking plate, a particularly good fastening seat of the striking plate 10 on the frame 1, which also withstands the greatest stresses, is finally achieved.

The assembly of the striking plate 10 is shown in FIGS. 1 to 4. It begins with the striking plate 10 first being inserted with the longitudinal edge 12 '' of its plate plate 12 facing away from its striking plate leg 13 into the outer profile groove 7 of the frame according to FIG. 2 in a direction transverse to the latter and then with the other longitudinal edge 12 ' the resilient profile inner projection 5 'is clipped in accordance with FIG. Then, by slightly shifting the striking plate 10, the striking plate 10 can be moved into its final fastening position shown in FIG. 4, in which the striking plate plate 12 with its longitudinal edges 12 ', 12''engages behind both inner profile projections 5' and 4 'in approximately the same width. Since the striking plate or its striking plate 12 is held in a slightly clamping manner by the aforementioned profile projections, the fastening screws 17, 18 can then be screwed in, as shown in FIG. The striking plate 10, which is thus finally fixed to the fixed frame 1 both with a screw and a form fit, is of high stability and security against break-in, in particular also largely secured against being levered out.

In the embodiment shown in Figure 7, the fixed frame 1 with the striker plate 10 attached to it is of the above-described design. Similar to the striking plate 10, the additional support of the push rod 21, which is mounted in the casement 20 in a longitudinally adjustable manner, is also formed here with the locking bolt 22 fastened thereon and engaging in the striking plate 10. For this purpose, on the guide rod 23 guided in the double-T-shaped profiled guide groove 23 of the sash frame 20, a guide plate 24 lying flat on it is fastened, which corresponding to the striking plate 12 covers the flat bottom 25 of the sash frame 20 containing the guide groove 23 in its entire width and which with its two longitudinal edges 24 ', 24' 'engages in the undercuts 20' '' present on the inside of both the wider side fold leg 20 'and the shorter side fold leg 20' 'of the sash frame 20.

Both the guide groove 23 present in the sash 20 and the push rod 21 which is adjustably mounted in it have a double-T profile, the locking bolt 22 being provided with an internally threaded bore 22 'into which a fastening screw 26 penetrating the push rod 21 engages. The guide plate 24 has a bore 24 ''', via which it is fixed immovably on the locking bolt 22. In this way, it is connected to the push rod 21 for entrainment. It goes without saying that on the push rod 21 there may also be several, for example about 50 mm long Guide plates 24 can be attached, which also move in the undercuts 20 ″ ″ of the sash frame 20 when the push rod is actuated by its corresponding movement thrust. Alternatively, the guide plate can have an elongated hole in the area of the locking bolt, in which the locking bolt can be moved back and forth.

With the above-described additional support of the push rod 21 via the guide plate 24 in the sash frame 20, effective protection against tearing out of these fitting parts in the event of a window break attempt is also achieved at this point in the sash frame, in combination with the striking plate plate fastened according to this invention. This advantage is achieved in that the guide plate lies directly in the longitudinal region of the engagement between the locking bolt 22 and the locking recesses 15 and 15 '.

In the context of the present application, a "flat bottom" is understood to mean an essentially flat region of the profile spar, which forms a mainly flat profile wall, which lies between the underside of the striking plate and the reinforcement profile. It is also essential that the fastening point of the striking plate in the hollow area of the spar is additionally provided with a metallic reinforcement insert.

In the special embodiment of such profile spars with side fold legs, the flat bottom is flanked on both sides of its long sides by the side fold legs.
