Abstract

Rails (9) are movably mounted on the edges of the frame or casement/leaf or in cavities or grooves, and are displaced by transverse pins (7) fitting into slits (8) which slope in relation to the lengthwise axis and run along the plane of the casement or leaf, or fit into a counter-groove (21) on the casement (1) or frame (2). The rails are connected by a corner-deflection at the corner of the abutting frame or casement/leaf sides. The rails are movable at right angles to the peripheral groove. The corner deflection has a housing fixed into the frame or casement/leaf and which is filled with filler material. The length of the rails with filler in the two corner deflections corresponds to the length of the rabbet.

Description

The invention relates to a fitting for windows or doors according to the Preamble of claim 1.

Such fittings are already known, for example from DE-AS 11 87 779. This is in a circumferential groove of the wing or the frame a longitudinally displaceable, drivable by an operating handle Drive member provided in the form of a drive rod, which by means of stationary, U-shaped guide pieces is mounted. In the drive member and each Guide piece are transverse, each to the longitudinal axis at an angle provided by inclined 45 ° slits, which are penetrated by a transverse pin become. During a movement of the drive member in the longitudinal direction, the Cross pins shifted within the slanted slots, causing a movement of the also traversed by the cross pin in a bore rail after draws. The movement of the rail takes place at an angle of 45 °, wherein the rail enters the counter-groove arranged on the wing.

On the rail, an additional U-shaped sealing rail is provided, consisting of Stainless steel or the like is executed. This lays down when Closing of the wing - due to their spring properties - to the Leg of the U-shaped grooves, namely the circumferential and the counter-groove on and closes the gap or the passage between the wing and Frame.

The drive links are at the window corners by chains, which over Idlers run, connected together to form a closed tension member. To achieve a reliable corner seal is on every corner except the Sealing rail provided an additional auxiliary sealing rail, which with a perpendicular to the longitudinal axis of the sealing rail extending leg on the respectively perpendicular to the rail accesses and with this is connected. When moving the rails, the move Corner seals perpendicular to each other, but stay together sealed.

This type of seal is very expensive, since the additional Auxiliary rails must be made and assembled. And that too is Moving the seals od each other in the penetration of dirt. Like. no longer given, so that sets a binding.

It is therefore an object of the invention to provide a fitting of the type mentioned To improve that the fitting is simple and inexpensive can be mounted while a reliable locking or sealing is guaranteed.

This object is achieved in that the rails perpendicular to the circumferential groove are displaced, that the corner deflection to be fastened in the frame Housing which is integrally formed with a filler, which the Corner of the frame fills in the opening position of the wing, the Length of the rails plus the filler pieces of the two corner deflections of Length of Rahmenfalzes corresponds.

By this configuration, it is possible that the corner area in a simple way and way to seal, as the perpendicular to the circumferential groove displaceable Guided rails with their longitudinal ends on the filling pieces and against them be sealed. There are no hard to handle and To be sealed inclined surfaces and it is not necessary that mutually displaceable - mutually sealing - additional Components are provided.

A particularly simple embodiment provides that the dimensions of the filler on the one frame leg of the height of the rail and the Dimension of the filler on the other frame leg of the height of the Rail plus the closing stroke of the rail corresponds. The filler receives thereby a rectangular shape, wherein the rails in the closed position in End abut each other while in the open position - if they So lie in the circumferential groove of the frame - invest in the filler. This aligns a boundary edge of the filler with the upper edge of the the circumferential groove lying rail.

Another embodiment of the fitting provides that the corner deflection a fixed to a filler guide channel having to pressure-resistant guiding of deflecting members, e.g. Spring steel bands, serves.

Such per se known transmission facilities in the corner of the Frame or sash are in connection with the filler of particular Advantage, since there is enough space for their accommodation and coverage is available. The guide channel and the deflector are a simple and easy to manufacture transmission device.

It is further envisaged that the housing of the Eckumlenkung the Drive links overlaps. In connection with the filling results from it the possibility of the radius of the guide channel and thus the deflection movement To make as large as possible, so that the tensile and shear forces occurring Drive elements can be optimally transmitted.

To move the rails optimally in locking position, is still provided that the filler pieces which are displaceable perpendicular to the circumferential groove Run rails. The rails receive an additional grip, so that the achievable seal and the locking forces can be optimized.

Further advantageous embodiments are in the description of the figures specified.

Fig. 1 shows a wing 1, on a frame 2 via a Hinge device 3 is pivotally mounted. The wing 1 can over a Locking device 4 fixed relative to the fixed frame 2 while being sealed at the same time.

The locking device 4 consists of a frame 2 arranged longitudinally displaceable, the drive member forming, flat rectangular Drive rod 5, on the periodically böckchenartige support members. 6 are arranged.

The support members 6 carry at its upper end transverse pins 7, which are transverse to Longitudinal axis of the drive rod 5 and the drive rod 5 on both sides laterally overtop. The transverse pins 7 are integral with in the illustrated embodiment formed the support member 6. The support members 6 are provided as moldings, which are attached to the drive rod 5 made of flat material. It However, it may alternatively be provided that the support member 6 has a bore in which an additional transverse pin 7 is inserted and fixed.

The drive rod 5 is interspersed with slots 22 at regular intervals and is penetrated herein by fastening screws 23 which are in a U-shaped, the drive rod 5 cross and laterally comprehensive holding member 24 find an abutment.

The cross pin 7 also engages with its ends in inclined slots 8 in the Embodiment U-shaped running rail 9 a.

The locking or unlocking one with such Locking device 4 equipped window is done by Longitudinal displacement of the drive rod 5, which is guided below the rail 9.

The rail 9 is mounted immovably in its longitudinal axis and is therefore through the transverse to the drive rod 5 transverse pins 7 from a groove 25, which is circumferentially mounted on the frame 2, perpendicular to the starting position in displaced a counter-groove 21.

The length of the rail 9 corresponds to almost the fold length of the frame 2, so that the rail 9 extending over the entire length of the fold region Lock acts. The rail 9 is over its entire length at several Make, preferably at regular intervals, of support members. 6 under attack. This ensures effective over the entire length and secure locking. At the same time, the exact fit of the groove 25 and the counter groove 21 in conjunction with the cross section of the rail 9 a reliable sealing of the wing 1 and 2 frame allows.

The height of the rail 9 therefore corresponds to a multiple of the distance from Frame 2 and wing 1 in the region of the groove 25, but preferably the two to three times that.

In Fig. 2 and 3, a rail 9 is shown in section. On the U-shaped Rail 9 is above the leg 10 a circular segment elevation eleventh attached, which - as shown, made of a different material. Preferably, the elevation 11 is formed integrally with the rail 9 and is together with this, for example by extrusion, produced.

The U-legs 26 engage around the support member 6, which on the drive rod. 5 is attached. At the upper end of the support member 6, the transverse pin 7 is provided, the width of which approximately corresponds to that of the rail 9.

The elevation 11 sets in the closed state to a complementary thereto shaped groove base 20 of an outwardly open counter-groove 21. The elevation 11th causes a seal of the wing 1 relative to the frame. 2

But it can also be provided that on the rail 9 a separate, on known seal in a longitudinal, undercut groove of the Rail 9 is provided, as shown in FIG. 3 shows.

It is also appropriate that the rails 9 on each frame spar the same Have cross-section. This will make the use of the same components facilitated.

The rail 9 shown in the embodiment of FIG. 1 is so designed that a production of plastic, for example by Extrude, offers. The slanted slots 8 are replaced by an additional Operation on the unabridged rails 9, for example by punching appropriate. The rails 9 can therefore be stocked in larger lengths be kept in stock. It is, but especially for the sake of the better Sealing and power transmission, also possible that the rail 9, as the Fig. 4 shows not provided with the slanted slots 8, but on a Intermediate profile 70 is attached by means of a latching device 71, wherein the intermediate profile 70 necessary for the engagement of the transverse pin 7 - not here has -Sschräschlitze 8 shown. A significant advantage of this Embodiment is that acting as a seal rail 9 no Interruptions o. Ä. Has and also no additional post for introducing the slanted slots 8 is required. The intermediate profile 70 can For example, consist of an extruded metal profile and - with respect its longitudinal axis - be relatively short.

If the intermediate profile 70 - as shown - as a U-shaped, to the inner Contour of the rail 9 applying, U-shaped profile formed on this Way the locking additionally strengthened, since that Intermediate profile 70 acts as a metal insert of the rail 9 and also with his upper horizontal web dips into the counter groove 21. At the same time this causes Intermediate profile 70 a total of stiffening the rail. 9

It is also for the safety of such a locking device conducive that the counter-groove 21 with a likewise U-shaped reinforcement o. Ä. made of metal to strengthen the connection. This can for example, by inserting or mounting a corresponding metal profile take place on the wing 1.

It should also be noted that the rails 9 lie in one plane of the frame, which is close to the outer frame cross-section. Through the rail 9 is namely, the penetration with burglary tool in the rebate gap prevented.

As is apparent from Figs. 5 to 7, the drive members in the form of Espagnolettes 5 on the vertical and horizontal legs 31 and 32nd drive-connected via a corner drive 33. The drive rods 5 are connected to the Corner 33 arranged on each leg of the corner 33 - Not shown - interconnected coupling points. The Eckumlenkungen 33 are provided in at least three of the frame corners, so that at each Holm of the frame 2 a rail 9 is located.

In Fig. 5, the corner deflection is shown slightly schematically.

If the rail 9 moved into the unlocked position, so are the perpendicularly extending ends of the rail 9 to a filler 38, which has parallel to the frame corner formed boundary edges.

The height of the filler 38 corresponds to the height X of the rail plus of the closing stroke Y. This ensures that the rail 9 in the Locking position abut each other.

As indicated in FIGS. 5 to 7, the longitudinal edge of the horizontal Leg 32 associated rail 9 at the front edge of the vertical Leg 31 associated with rail 9 at. The mounted on the rail 9 Seal (e.g., elevation 11) causes a reliable seal the end face of the perpendicular thereto extending rail. 9

FIGS. 6 and 7 show the corner region of the frame 2 less schematically than Fig. 5. The only partially shown rails 9 are connected via a Drive mechanism 40 from the unlocking or shown in Fig. 6 Opening position shifted to the locking position shown in Fig. 7. The Rails 9 are thereby along the lateral boundary edges 41, 42 of the Filler 38 out. In the unlocking position of FIG. 6, the rail is 9th almost flush with the frame rebate 43, 44 of the vertical and horizontal Leg 31 and 32. The filler 38 also has at least one his thighs on a dimension, which is a flush on the Frame fold 43 or 44 allowed.

This will be a possibly occurring opening in the corner area both in the Opening position and prevented in the locked position. For the User results in an open wing almost completely smooth Folding surface of the frame, od of which no functional parts of the fitting. Like. Project what is of particular advantage.

The rail 9 is designed such that it is color matched to the frame 2. In this case, both the rail 9 and the rebate area of the frame by the smooth surfaces easy to clean and, if necessary, the rail 9 can even do this be removed.

The assembly of such a fitting can on the one hand take place in that First, the attachment of the Eckumlenkungen 33 in the corner of the frame. 2 he follows. The lying between the Eckumlenkungen 33 connecting rods 5 are cut to length and fixed by means of the fastening screws 23. The also be adapted to the size of the frame 2 rails 9 finally pushed or clipped onto the support members 6.

On the other hand, the assembly can also be done so that the first between the corner areas lying drive members in the form of the drive rods. 5 minus a measure of the length of the rails determined by the corner deflection be adapted to the frame and the holding members 24 by means of Fixing screws 23 (Fig. 1) are attached. The corner deflections 33 are then placed in the corner and fixed. Finally are also tuned to the Holmlängen of the frame 2 rails 9 attached to the support members 6 or the intermediate profile 70. An assembly of Fitting parts on the wing 1 is apart from the hinge device. 3 and a possibly to be arranged U-shaped reinforcement in the counter-groove 21 is not necessary.

FIG. 8 shows a schematic overview of the components of the Driving rod drive. In each frame corner is a corner 33rd intended. The filler 38 of the Eckumlenkungen 33 are doing in one preferred embodiment arranged so that the height of the filler 38th - According to the height X of the rail 9, not shown - plus the Schließhubes Y each parallel to the horizontal leg 32 of the frame. 2 runs. By this arrangement, not only causes the respectively opposite rails 9 get the same length, but also that the rails 9 with respect to the wing 2 each occupy the same position. This also ensures that each adjacent to each other Drive mechanisms 40 ', 40 "are the same design 40 'and 40 "can namely - as shown in FIGS. 6 and 7 - be formed differently. The drive mechanisms 40 ', 40 "are in the illustrated embodiment of the Eckumlenkungen 33 each in one piece to this arranged. This allows the Eckumlenkungen 33 for each frame corner use or it is only one embodiment of a Eckumlenkug 33rd necessary. This facilitates on the one hand the storage and the production of the Eckumlenkungen 33, on the other hand, but also for the assembly of Corner deflections 33 of great advantage. For smaller wing dimensions can namely arranged on between the Eckumlenkungen 33 Drive mechanisms 40 are omitted, so that the effort for attachment this and necessary couplings with the drive rods 5 is avoided.

Finally, it should be noted that the rail 9 at their respective End still with - not shown - end caps 9 'can be sealed. These end caps 9 'are for better sealing with a profile of Rail 9 adapted contour provided.

These end caps 9 'are shown in FIG. 9. Preferably, the End caps 9 'connected via a latching snap connection with the rail 9. The end face of the rail 9 is closed by the end cap 9 ', so that in adjacent rails 9 - as shown in phantom in Fig. 5 - Seal the rails 9 against each other. For this purpose, as shown in FIG. 9, the End face of the end cap 9 'complementary to the cooperating Surface of the rail 9 shaped.

Of particular advantage is that the rails 9 not at the same time be moved. As is apparent in particular from FIGS. 6 and 7, the in the drive mechanisms 40 and 40 'provided slotted guides 50' or 50 "differently formed the rail 9 along the horizontal frame leg 32 already after a short switching path of the drive rod 5 is moved. The rail 9 am vertical frame leg 31 is only at a much later date emotional. The rail 9 of the horizontal frame leg 32 is to this Time already completely moved out of the groove 25 and is - by the Drive mechanism 40 'held - fixed. The rail 9 of the vertical Frame leg 31 abuts laterally against this fixed rail 9.

By this measure prevents the rails 9 in the end rub against each other, causing damage to the rails 9 and / or the could lead to associated seals. Under certain circumstances are also optical to fear disturbing sanding marks on the rails 9.

The arrangement of the filler 38 of the Eckumlenkungen 33 of FIG. 8 illustrated embodiment can of course also rotated exactly 90 °, as shown in Fig. 5, take place. It is essential that each at the same Frame legs 31, 32 arranged Eckumlenkung 33 a same orientation the drive mechanism 40 has. The orientation of the filling pieces 38 takes place in each case a mirror image of the axes of symmetry of Frame legs 31, 32.
