Description

The invention relates to a locking fitting for windows or doors with a plurality of arranged on the fixed window or door frame locking plates, which are engaged by sash-side locking elements, wherein the locking plates are placed at predetermined intervals on a along the frame cornice side, and on the overlapping surface of the sash overlay and attached each locking plate is designed as a separate fitting.

Such a locking fitting for windows or doors is known from FR-A-22 68 933. Such a locking fitting has the advantage that the assembly of the locking plates attached to the overlapping surface of the wing flap means a certain simplification. A disadvantage of this known locking fitting, on the other hand, is that when the overlap of the wing spars is profiled in accordance with the standards, in particular when wooden wings of the window or door sashes shrink, an insufficient overlap of the wing overlap can occur. This disadvantage is partially eliminated by the rail covering a possible gap. However, especially when the fitting is to be recessed into the rebate, there are still spaces that prevent a guaranteed tight seal between the sash and frame.

The invention is therefore based on the object to provide a fitting with a plurality of locking plates of the type mentioned, in which a tight closing and sufficient overlap of the normal wing overlay is ensured and which is nevertheless simple and economical to produce and easy to assemble.

This object is achieved in that the locking plates are arranged in recesses or interruptions in the rail and are fixed by these at intervals.

The fact that the locking plates are accommodated in the recesses of the rail, firstly the rail is closed again despite the previously provided recess and secondly the positioning of the locking plates is considerably simplified, so that despite the simplest assembly a guaranteed tight closure between the sash and frame is guaranteed.

The rail can take various forms. You can e.g. B. form an angle in cross section or be U-shaped. It can also consist of a tube. It is only important that the side of the rail running along the narrow side of the frame is at the same angle to one another to the side lying on the overlap surface as the narrow side of the frame to the overlap surface of the wing flap. The use of a tubular rail is recommended if the rebate chamber space remaining even with a cross-sectionally angular or U-shaped rail is to be reduced or covered. Furthermore, the rail can be profiled in such a way that it also allows the sealing profile, which is generally arranged next to the locking plates, to be taken up at the same time. This eliminates the previous weak point between the sealing profile and the rebate chamber.

The recesses can only be provided in the side lying against the wing flap, or in the case of a U-shaped rail in the two lateral legs of the rail which is otherwise continuous. However, the rail can also consist of individual rail sections adjoining the locking plates, each locking plate having recesses for the form-fitting, flush reception of the ends of the adjacent rail sections.

With such a fitting, a sufficient overlap of the sash overlay is achieved at every point between the frame and sash with a tight closure. A particular advantage of the fitting according to the invention is that the interruption of the rail in the area of the strikers makes it possible to adapt to different frame sizes and to the right and left hinges in the simplest way without the need for expensive storage. The production of the rails from common profiles and the installation of the rails and strikers on the frame is simple and economical. The locking plates and the sections of the rail spanning them can be fastened to the frame by common fastening means. Likewise, the sections of the rails can be clamped on the narrow side of the frame by means of locking plates which act as clamping tabs. The locking plates can also be non-detachably connected to the rail, which results in an overall element that makes it easier to attach the fitting.

Die in den Fig. 1a und 1b gezeigten Beschlagteile bestehen aus einer Schiene 1 mit U-förmigem Querschnitt, deren beide Schenkel 2 in durch die Riegelelemente 15, 25 festgelegten und dem Abstand der Schließplatten 4 entsprechenden Abständen mit Aussparungen 3 versehen sind. Die Schließplatte 4 besteht aus einer rechteckigen Platte 5, deren Breite maximal dem Abstand zwischen den beiden Schenkeln 2 der U-förmigen Schiene 1 entspricht, und zwei beispielsweise angegossenen oder angeschweißten Formstücken 6. Die Formstücke 6 sind im wesentlichen Quaderförmig und sind an den einander zugewandten Seiten 7 mit Abschrägungen 8 zum Einlauf eines Riegelelementes versehen, die, zusammen mit den Seiten 7, vom Riegelelement hintergreifbare Wangen bilden. Die Formstücke 6 sind dabei so an der rechteckigen Platte 5 befestigt, daß ihre äußeren Seiten 9 so weit an den Längskanten der Platte 5 vorstehen, daß sie, wenn die Schließplatte 4, wie aus der Fig. 1 b ersichtlich, in die U-förmige Schiene 1 eingesetzt ist, bündig mit den Aussenseiten der Schenkel 2 abschließen. Die Schließplatte 4 wird so in die Schiene 1 eingesetzt, daß ihre Formstücke beispielsweise an den unteren Kanten 10 der Ausparungen 3 anliegen. Die Aussparungen 3 sind dabei so dimensioniert, daß ihre Länge wesentlich größer als die der Formstücke 6 ist, so daß oberhalb der Formstücke genügend Raum für das Eingreifen des Riegelelementes in den Bereich der Schließebene verbleibt. Die Schließplatte 4 ist an ihrem oberen und unteren Ende mit Bohrungen 11 versehen und ist mit der U-förmigen Schiene 1 beispielsweise durch Nieten oder Schrauben verbunden. Die U-förmige Schiene 1 ist ebenfalls mit Bohrungen 12 versehen, die zum Anschrauben der Schiene an der Schmalseite eines feststehenden Rahmens 13, wie in der Fig. 2 dargestellt, dienen. Die Bohrungen in der Schließplatte und der U-förmigen Schiene können auch zueinander fluchtend angeordnet sein, so daß die Schiene und die Schließplatte mit gemeinsamen Befestigungsmitteln, beispielsweise Schrauben, am Rahmen befestigt werden können. Die vorbeschriebene beiderseitig spiegelsymmetrische Ausbildung der rahmenseitigen Teile des Beschlages erlaubt deren Verwendung für Rechts- oder Linksanschlag.Embodiments of the present invention are described in detail with reference to the following figures. It shows :

• Figures 1a and 1b, the frame-side parts of a fitting according to the invention in an exploded and in an assembled perspective view;
• Figure 2 shows the fitting of Figure 1 in section along the section line 11-11 in the installed state in the closed position.
• Figure 3 shows the frame-side parts of another fitting according to the invention in a perspective view;
• 4 shows the fitting according to FIG. 3 in section along the section line IV-IV in the installed state in the closed position;
• Figure 5 shows a variant of the fitting according to Figures 1 and 2 in a perspective view. and
• Figure 6 shows a variant of the fitting according to 3 and 4 in a perspective view.

The fittings shown in FIGS. 1a and 1b consist of a rail 1 with a U-shaped cross section, the two legs 2 of which are provided with recesses 3 at intervals defined by the locking elements 15, 25 and corresponding to the distance between the locking plates 4. The locking plate 4 consists of a rectangular plate 5, the width of which corresponds at most to the distance between the two legs 2 of the U-shaped rail 1, and two, for example, cast-on or welded-on shaped pieces 6. The shaped pieces 6 are essentially cuboid in shape and face one another Pages 7 are provided with bevels 8 for the entry of a locking element, which, together with the sides 7, form cheeks which can be gripped behind by the locking element. The fittings 6 are attached to the rectangular plate 5 so that their outer sides 9 protrude so far on the longitudinal edges of the plate 5 that when the closing plate 4, as can be seen from Fig. 1 b, they are in the U-shaped Rail 1 is inserted, flush with the outside of the legs 2. The locking plate 4 is inserted into the rail 1 in such a way that its shaped pieces rest, for example, on the lower edges 10 of the recesses 3. The recesses 3 are dimensioned such that their length is substantially greater than that of the shaped pieces 6, so that above the shaped pieces there is sufficient space for the locking element to engage in the region of the closing plane. The closing plate 4 is provided with holes 11 at its upper and lower ends and is connected to the U-shaped rail 1, for example by rivets or screws. The U-shaped rail 1 is also provided with bores 12, which are used to screw the rail onto the narrow side of a fixed frame 13, as shown in FIG. 2. The bores in the locking plate and the U-shaped rail can also be arranged in alignment with one another, so that the rail and the locking plate can be fastened to the frame using common fastening means, for example screws. The above-described, mutually mirror-symmetrical design of the frame-side parts of the fitting permits their use for right or left hinging.

As can be seen from FIG. 2, the rail 1 fastened to the frame 13 acts with its locking plate 4 with a locking element 15 arranged on the wing 14, through a recess of a faceplate 30 connected to a drive rod 31, so that this via the recess 3 Cheek 7 of the shaped piece 6 facing the wing flap can reach behind and is held without rattling. Through the leg 2, the U-shaped rail 1 fastened to the narrow side of the frame 13 over its entire length, sufficient overlap of the wing overlap is ensured between the frame 13 and the wing 14 even with normal wing overlap.

In the embodiment of the fitting according to the invention shown in FIGS. 3 and 4, an angular rail 16 is used, which connects to a locking plate 17 in individual sections. The closing plate 17 is essentially cuboid and has a T-shaped recess 18 which is advantageous for right and left stop for forming cheeks 19 which can be gripped behind. At the two upper and lower ends, the closing plate 17 is provided with angular recesses 20 for flush reception of the legs 21, 26 of the angular rail 16. This rail can be unequal legs and correspond to the width and thickness of the closing plate 17, or have economically advantageous, same legs. The closing plate 17 can be screwed or riveted to the rail 16 via the bores 22, or can be fastened to the fixed frame 23 together with the rail. The bores 22 can also be arranged outside the region of the cutout 20, and the depth of the cutouts 20 can be dimensioned such that the sections of the rail 16 are fixed by clamping action. This eliminates the bores 27 aligned with the bores 22 and the preparation of the individual sections of the rail 16 is thus facilitated.

As can be seen from FIG. 4, the closing plate 17 interacts in a similar manner as described above with reference to FIGS. 1 and 2 with a locking element 25 which is arranged on the wing 24. Here too, the recess 18 in the closing plate is dimensioned such that rattle-free closing takes place.

In the embodiment shown in FIG. 5, the closing plate 4 is arranged in a U-shaped rail 1, similar to that described with reference to FIG. 1. The rail 1 is provided with a rail part 29, which forms a groove 28, along the leg 2 remote from the wing flap. This groove 28, which is shown in dashed lines in FIG. 2, serves to accommodate the sealing profile 32 generally provided for windows and doors today. At least the bores 11 must be coordinated so that the locking plates 4 can also be mounted pivoted through 180 ° to guarantee the right and left stop. As can be seen from FIG. 5, in such a widened rail 1, 29, recesses 3 are provided only in the stop-side leg 2 of the rail 1, while the other leg 2 is continuous. In order to be able to accommodate the locking plate 4 with the shaped pieces 6 projecting on both sides, the U-shaped rail 1 has a corresponding distance between the two legs 2.

FIG. 6 shows a variant of the embodiment described in FIGS. 3 and 4. Instead of the angle rail 16, a square tube rail 33 is provided here, which is flush with the closing plate 17, which is used to receive the square tube 33 on its Each end is formed by recesses 20 with a shoulder 34 with a reduced cross section. As soon as the bores 22 are not arranged outside the lugs 34 in order to facilitate the lashing of the individual sections of the square tube 33, the end of the square tube 33 is provided with a bore 35 which, when plugged in, is aligned with the bore 22 of the closing plate 17, so that square tube 33 and locking plate 17 can be connected by screwing together and on the fixed frame.

The fittings described above can be used for right and left hinges without additional effort despite the composite design and can be adapted to any window and door size by simply selecting the rail length.
