Description

The invention relates to a hidden arranged in the fold fitting for turn-tilt windows or doors according to the preamble of claim 1.

Windows or doors of this type are already known, such as the EP 1 612 354 A2 . EP 0 204 267 B1 and the DE 8718109 U1 can be removed.
After EP 0 204 267 B1 the two arms have different lengths and each have a pivot joint with the corner bearing and the corner band in conjunction, in such a way that they form with these a handlebar trapezoid whose shorter member is the wing-side arm.

The connection to the frame-side pivot of the long arm with the fixed to the corner band hooks is secured by a locking ring which engages in a arranged near the free end of the hook circumferential groove. The hanging with subsequent backup against disengagement of the wing to the frame, can only be done in the rotational position.

In the embodiment according to DE 87 18 109 U1 are a total of three links arranged, with a short first arm and a second long arm are hinged to a mounting plate of the corner bearing fixed to the wing. The third link is pivotally guided in the corner bearing and like the second long arm secured to the frame-side corner band non-decoupled non-decoupled via a power storage.

It would be conceivable, even in the embodiments of DE 87 18 109 U1 appropriate construction and function either the two wing-side connecting joints or the two frame-side connecting joints for the two arms - similar to EP 0 204 267 B1 - train decoupled. However, as practical tests have shown, in both cases, in particular when mounting the wings, so far difficulties a, as the distances between the free hooks of the two links and the distances between the associated engagement openings to form the pivot and the sliding joint on the bearing rail or holding rail in no fixed relationship to each other.

It is therefore associated with considerable difficulties to bring the decoupled joint points when hanging the wing together again in proper operative connection. During the implementation of the suspension operation, namely, the functional parts of the rotary joint and the functional parts of the sliding joint have to be aligned relative to each other exactly.

It is therefore an object of the invention to overcome the above-indicated shortcomings in windows or doors of the generic type.

Therefore, the object of the invention is to provide a concealed hinged fitting for tilt and turn windows or doors, in which a simple and safe on and Aushängemöglichkeit available for the wing on the window frame while the permanently safe opening and closing function guaranteed for the wing.

The achievement of the object is achieved by the features of the characterizing part of patent claim 1. The subclaims relate to further advantageous embodiments of the invention.

The advantage of the solution principle is that the corner band can be mounted without the aid of special stop gauges on the folding surface of the wing, since the fitting part provides means for Lagejustierung in the longitudinal direction of the fold, wherein a bearing rail of the corner bearing with its free end to the upright Falzumfangsfläche of the frame almost rests and wherein at the opposite end of the free end and on the side facing away from the links side components are also attached to fix the position. The corner band is doing with an angle-shaped support rail by means of a Falzumfangsfläche the wing upright hinge for position adjustment use. With this assignment also necessary for the opening and closing of the wing, exact alignment is ensured to the frame.

In all the above-mentioned types of opening in particular in the rotated position of the fitting and tilt position of the wing 2 to the frame 1 of the window or the door, it is essential that the wing relatively easy to hang the frame and with as few and simple handles easily again hang out. This is done in an advantageous manner in that the hooks of the support arms with the holes of the retaining rail in the retracted state have the same distance dimensions and thus are in congruent position to each other.

The reliability has been optimized by the invention in that at least one hook in the bore can be clipped during assembly and thus enter a permanent, but again manually releasably fixed and immovable connection in the assembled state.

It has proved to be particularly advantageous according to the invention, when the corner bearing is coupled to the corner hinge during assembly in the retracted state of the fitting parts in a limited tiltable arrangement. In this case, the hooks can be designed so that they have at their free ends a chamfer and / or have the holes corresponding to a chamfer or taper. But also the height of the hook is adjusted accordingly. Over-designed hooks can adversely affect easy installation of the wing in tilted position. Therefore, the hooks in their height and bevel are adapted to the holes.

In order to achieve a large Ausstellweite the wing in rotational position, the bearing rail handlebars are advantageously assigned, which consist of a drehverschiebbaren control arm and a first rotatably mounted support arm, which in turn is scissor-like rotatably connected to the control arm, wherein a second support arm rotatable on the free End of the control arm is attached.

It is particularly advantageous if the hook to the hole for coupling are in alignment position and the connection is almost free of play. Especially with a narrow structure of the window or the door, it is particularly advantageous if the fitting parts are designed adapted to the wing and frame to avoid reworking the profile. An offset to each other either requires more space or weakens the component to which the hooks are hinged. With the almost backlash adjustment of the components to be coupled a quick response to control the wing is achieved in the rotational position.

It is advantageous according to a further feature of the invention that the hooks have at the corners facing the free ends of a chamfer, wherein at least one hook is provided at a distance below this with a circumferential groove. The chamfer has that as a result, several beneficial effects. On the one hand, the chamfer provides the necessary scope for tilting the wing for mounting and unmounting, but also for the normal tilting position, on the other hand, the chamfer allows the joining of an already spring-loaded securing member, which is mounted in the corner band in the region of a bore and finally in one of Bevel the following circumferential groove snaps. With the fixed position of the corner band to the corner bearing is the wing to the frame in the mounted position and with subsequent hanging a Ausstellschere above and by switching the fitting from the rotational position to the tilted position, the window or door in all positions and switching in each opening position captively secured and ready for use.

Structurally simple and economical to manufacture according to the invention, when the securing member consists of a seated in the corner band U-shaped spiral spring rod which is clamped at its free ends and engages tangentially in the circumferential groove of the hook.

In order to secure the securing member from falling out of the corner band, a cap on the insertion of the securing member cutout, for example by clipping, is inserted in an advantageously simple manner.

To release the fixation of the corner band from the corner bearing, i. for hanging the wing, the invention provides in an advantageous embodiment in the corner band axially parallel but laterally offset from the bore a projection which is tapered on the side surfaces, being spread by longitudinal displacement of the securing member on the side surfaces of the spiral spring rod and herausdrängbar from the circumferential groove of the hook is.

Simplified and cost-effective, the longitudinal displacement of the securing member is when the closed other end of the U-shape is spaced at a distance in a fixed position from the corner band and the closed end of the U-shape is angled to obtain a handle possibility, with Move the distance corresponding to the corner band enlarged.

An expedient, because simple and inexpensive production of the corner band is ensured when it is designed symmetrically in the assembled state to the longitudinal center plane and made by injection molding.

According to a further feature of the invention according to claim 1, the links of the corner bearing with the bearing rail are aligned almost congruent when mounting the wing to the frame. This position corresponds to the mounting position of the wing to the frame, i. the distances of the hooks of the corner bearing correspond to the distances to the holes of the corner band. At the same time, the corner bearing in the retracted position of the handlebars offers the smallest space and thus an optimum mounting state.

Further advantages will become apparent from the description and the drawings, which are described in detail with reference to several embodiments shown in the drawings.

In the FIG. 1 the drawing shows a window or a door is shown, in which the frame 1 associated in the drawing not visible fitting on an actuating handle 3 of the wing 2 is in a rotational position and the wing 2 to the frame 1 in tilt position in a pre-assembled detachable arrangement stands. In the concealed in the fold fitting for turn-tilt windows or doors, a not visible Ausstellvorrichtung is at the upper edge of the wing 4 and provided at the lower edge of the wing 5 a visible in the wing section fitting 6, which between the wing 2 and the frame. 1 is arranged, wherein the upper Ausstellvorrichtung the Kippöffnungsstellung of the wing 2 relative to the frame. 1 limited, and between the upper horizontal bars of frame 1 and wing 2 is installed. Both the upper Ausstellvorrichtung and the fitting 6 correspond to the same kinematic structure.

The fitting 6 is evidently the FIG. 2 in this case from a hinged at the wing 2 corner hinge 7 and a fixed to the frame 1 via a bearing rail 8 hinged corner bearing 9, which over at least two FIG. 5 have three links 10, which are in pivotal connection to each other, wherein the links 10 on at least one of the free ends 11,12 after FIG. 3 have a bolt-like hook 13,14. In this case, at least one of the hooks 14 on a corresponding holding means 15 for releasable fixation with the corner band 7.

In addition, the corner band 7 is mounted without the aid of special stop gauges on the rebate surface of the wing 2, since the fitting provides means 17 for Lagejustierung in the longitudinal direction of the fold, wherein at the corner bearing 9, the bearing rail 8 with the means 16 at the free end 18 at the upright Falzumfangsfläche the frame 1 almost rests and wherein at the opposite end of the free end 18 and on the side facing away from the links 10 side components are also attached to fix the position. The corner band 7 is used with an angle-shaped retaining rail 19 by means of a Falzumfangsfläche the wing 2 upright hinge 20 for position adjustment use. With this assignment, a necessary for the opening and closing operation of the wing 2, exact alignment is ensured to the frame 1 also.

In all the above-mentioned types of opening, in particular in the rotated position of the fitting and tilt position of the wing 2 to the frame 1 of the window or door, it is essential that the wing 2 can be relatively easy to mount the frame 1 and with as few and simple handles , the leaves 2 hang out again easily. For this purpose, the hooks 13,14 of the handlebar 10 in the extended and retracted state have the same distance dimensions to the holes 21,22 of the retaining rail 19, wherein they are in readiness for assembly after FIG. 1 and FIG. 2 stand with retracted arms 10 in a congruent position to each other.

In order to permanently secure the connection between the wing 2 and the frame 1 in the mounted state during the course of motion, at least one connection between the hook 14 and the bore 22 can be clipped. On the other hand can the connection can only be resolved again with the help of manual actuation.

The hanging of the wing 2 in the frame 1 is also facilitated so that the arranged on the corner bearing 9 hooks 13,14 at least partially have a chamfer 23,24 and the hooks 13,14 facing holes 21,22 as necessary, an extension in Shape of a chamfer or a taper may include in order to hang in a limited tilting position of the wing 2 to the frame 1 can. As already mentioned, is in the embodiment according to FIG. 1 , according to which the wing 2 to the frame 1 shows the limited tiltable mounting position, the fitting in rotational position. However, regardless of the mounting of the wing 2 to the frame 1, the fitting may also be in tilted position, but the fitting would have to be switched due to the closure side tilting mirror component in the rotational position on the actuating handle 3.

The controllable by the handlebars 10 fitting 6, among other things from the already described corner bearing 9 after FIG. 5 formed, after which the handlebar 10 consists of a rotatable about a pivot 28 on the bearing rail 8 control arm 25 and also on the bearing rail 8 by means of a hinge 29 thereto first long rotatably mounted support arm 26, which in turn scissor-like with the control arm 25 via a hinge 30 is rotatably connected, wherein a second short support arm 27 is rotatably mounted by a hinge 31 at the free end 32 of the control arm 25. Each of the support arms 26,27 opposite ends of the hinges 29 and 31, the hooks are firmly articulated 13,14, which in turn are mounted in the mounted state in the holes 21,22 of the corner band 7.

After the FIGS. 2 to 4 the corner band 7 includes a holding means 15, which consists of a spring-loaded securing member 33. The corner band 7 has in this case in the partial region of the holding means 15 a cutout 34 which is filled by a cap 35 after assembly of the individual components of the securing member 33 most part again. The cap 35 is thereby either non-positively connected by fastening screws or positively by clipping with the corner band 7. Thus, the securing member 33 receives a secured position within the corner band 7. At the respective ends 36,37 of the cutout 34 two spaced from the longitudinal center plane 38 grooves 39,40 are provided, which in turn is a U-shaped Biegefeder rod 41 record with cross-sectionally round spring wire, in such a way that the free ends 42 are clamped and a portion 43 is guided near the end of the closed U-shape 50.

The spiral spring rod 41 is partially enclosed between the cap 35 and the corner band 7, preferably produced by injection molding, so that inadvertent displacement of the securing member 33 in the wrong direction is avoided. Thus, the spiral spring rod 41 for disengaging the support arm 27 and thus the wing 2 can be pushed out of the circumferential groove 45 of the hook 14, axially parallel but laterally offset from the bore 22,44 in the region of the cutout 34 of the corner band 7, a projection 46 is formed on its side surfaces 47,48 tapers facing the bore 22,44. On the side surfaces 47,48 is adjacent to both sides of the spiral spring rod 41 is formed, which bends with displacement in the longitudinal direction - ie at distances from the corner belt 7- in the region of the bore 22,44, so that the tangentially arranged on both sides spiral spring rod 41 from the circumferential groove 45 of Hook 14 arrives. To simplify the handling for moving the securing member 33, a distance 49 is provided from the end of the corner band 7 to the closed U-shape, which in the latched state after FIG. 3 at least finger width is and by manual operation in the direction of arrow to FIG. 4 , so without further aids, enlarged accordingly. For improved grip, the securing member 33 is angled in the region of the closed U-shape 50 about the height of the folding air, not shown, by 90 °.
