Description

The invention relates to a side fitting for Tilt and turn windows, doors or the like, according to Preamble of claim 1.

DE 198 11 373 A1 describes a generic type Side fitting known. It has a wing-side Band part on that at one end of an ax arm an axis of rotation is pivotally attached. In addition, the side fitting has an insert that has an elongated hole. In the slot the other end of the ax arm with one from the ax arm outgoing cones. So the ax arm is swiveling and longitudinally displaceable in the slot the insert articulated. At the back the insert can be a guide device for a drive rod may be provided. Furthermore, Side fitting a coupling part, which with the insert is connected. If a position or position of the side fitting is present in which the insert and the ax arm overlap or partially overlap each other and the length of the insert and the ax arm in substantially the same direction show, the coupling part encompasses the ax arm partially, so that this with a rotary opening movement the window is supported, reducing the weight the window is not completely at the Bearing point added between the arm and insert must become.

The well-known side fitting is for right as well can also be used for left-hinged windows. If a change from a stop page to the other stop side, the well-known Side fitting, however, is broken down into its components become. In particular, the coupling part from Insert, the wing-side hinge part of the ax arm and the coupling part is separated from the insert or dismantled. The conversion the stop side is therefore quite cumbersome. In addition, when inserting the side fitting in a circumferential groove of the window sash an installation sequence is observed. The means the individual components of the side fitting are not yet connected, and must one after the other and in a certain order the circumferential groove are introduced. It can be too Confusion comes about, making a proper one Function of the side fitting is not possible. to The individual components must correct this error can be removed again individually.

It is therefore an object of the invention, a generic Specify side fitting, which also during the change from, for example, right to Left fitting of the side fitting is not complete must be disassembled.

This task is solved with a side fitting, which shows the features of claim 1. Therefore becomes a side fitting for tilt-and-turn windows, -Doors or the like, suggested which one wing-side hinge part, an ax arm, a coupling part and has an insert. The band part is pivotable about an axis of rotation attached to one end of the ax arm. The coupling part is connected to the insert. The other End of the arm is by means of a rotating connection swiveling and longitudinally displaceable on the insert performed, this slewing ring Slot of the insert and one guided in the slot Has pin, preferably from the arm emanates. According to the invention it is provided that the coupling part is mirror-symmetrical to its transverse central axis trained and in two different, layers on the insert offset by 180 ° to each other is definable. Each layer is a stop side assigned to the window sash. By the mirror-symmetrical design of the coupling part can do this when changing the stop side remain on the insert and only has to are moved about a pivot axis so that the two Layers can be taken up by the coupling part, without disassembling the side fitting. According to the invention it is also provided that -in fixed Position of the coupling part itself Elongated hole of the slewing ring made of two, in the longitudinal direction of the pin aligned partial elongated holes composed, one of which is in the coupling part and the other arranged in the insert are. In a defined position, they overlap both partial elongated holes, so that the one mentioned above Longitudinal movement of the ax arm guaranteed is. As - as described above - the coupling part also mirror-symmetrical to its transverse central axis trained, the overlap Partial long holes of the slewing ring in both positions of the coupling part. That is, in the different Layers overlap the partial elongated hole of the coupling part and the partial long hole of the insert, so that almost a single slot, namely that of Slewing ring, is formed. The mirror symmetry the coupling part does not necessarily refer on its outer contour, but on the functionally important ones Parts.

The fact that the pin of the slewing ring through the elongated hole or through the partial elongated holes reaches through, needs for switching the stop side of the coupling part only from Insert piece are loosened so that it is about the peg can be rotated so that the two different Positions of the coupling part offset from one another by 180 ° can be taken.

According to a development of the invention, that the slewing ring as a captive of ax arm, coupling part and insert effecting rotary connection is formed. For this purpose it is preferably provided that the pin - As mentioned above - from the ax arm that Coupling part and the insert extends through and has a head at its free end, the Diameter is larger than that of the pin. With this is also known as a mushroom cone the captivity in a particularly simple manner of ax arm, coupling part and insert accomplished. When changing the stop side So only the connection between the coupling part and insert are solved so that then the coupling part in the other position can be brought.

According to a development of the invention, that the coupling part on the insert by means at least one realizing the connection Screw connection can be determined. So this will be Loosened screw connection, so the coupling part pivoted with respect to the insert and the arm so that one or the other Location of the coupling part is ingestible. After the changeover is the coupling part again with the Screw connection can be fixed on the insert. It is also provided that the screw connection symmetrical to the transverse central axis of the coupling part lying fasteners on the coupling part and Has insert. So it can be provided that only one through hole is provided on the coupling part is and on the insert, for example Threaded hole. Thus, for the screw connection a screw through the one present on the coupling part Inserted hole and in the threaded hole of the insert are screwed tight. There at least one screw connection is provided, it is sufficient if only one fastening means on the coupling part, thus a through hole is provided is, then preferably on the insert two threaded holes or fasteners are provided. The hole respectively the fastener on the coupling part is then with respect to the transverse central axis of the coupling part so that there is a fastener in both layers, for example the threaded hole, on the insert is aligned so that the screw connection can be produced.

In a preferred embodiment it is provided that on the wing-side hinge part a locking device in two different, offset by 180 ° to each other lying layers can be fastened. This locking device interacts with a counter-locking device, which can be provided on a drive rod. Are locking devices and counter-locking devices engaged with each other, the ax arm with respect to the wing-side hinge part can not be pivoted. The side fitting is in this functional position intended for the opening of the window sash. Are not locking devices and counter-locking devices engaged with each other, so from the window sash the tilt opening position are taken in the the ax arm relative to the insert and to the band part is pivoted. The ax arm takes over the tilt opening limit, that is, it limits the tilt opening path of the wing. Because that Locking device in two different positions, 180 ° to each other staggered layers can be attached to the belt section the locking means can also be special simply switched to change the stop side become.

In a preferred embodiment it is provided that the locking means is pivotally mounted about the axis of rotation is. That is, the locking means has one Axis of rotation, which is at the end of the arm which also the band part is pivotable with respect to the Axer arm is mounted.

According to a development of the invention, that the attachment of the locking means on Belt part by means of at least one screw connection takes place, diametrically opposite of the fastening means trained to the axis of rotation on the belt part are. In other words: the locking device is on a fastener is provided, whereas on Band part two fasteners may be provided can, so that the locking means in each of the two Layers were firmly connected to the wing-side hinge part can be. The fact that the axis of rotation of the Closing means and the hinge part coincide, can also switch the stop side for these parts are relatively easy to do because only the screw connection loosened, the band part in his is to bring another situation, and then the Screw connection can be restored and such a tight coupling between the band part and Closing means is made.

A preferred embodiment stands out characterized in that on the insert and on the coupling part Locking device for pre-fixing the two by 180 ° layers offset from one another are. This means that the locking means on the insert and coupling part are present that the relative position between insert and coupling part is prefixable, so that in a simple way the connection between insert and coupling part can be carried out, that is, that Coupling part with respect to the insert in both Layers can be pre-fixed by means of the locking means, whereby in a simple way the aforementioned Screw connection between coupling part and Insert piece can be executed. In the pre-fixed Position the fasteners are in alignment on coupling part and insert.

Further refinements result from the subclaims.

The side fittings also known as side scissors of the type mentioned here in particular with arched windows or with windows used where the upper cross member is not parallel runs to the lower cross member. With these Windows are fittings that both turn and also allow a tilt opening of the wing in the Most cases cannot be attached to the upper cross member. It is therefore a turning and Fitting to enable tilt opening position a side rail of such windows attached. However, these windows are also for legal as well also intended for left-handed use.

Figure 1 shows a side fitting 1 for a turn-tilt window, door not shown here or similar. At the side fitting 1 can a drive rod 2 can be slidably guided.

The side fitting 1 has a wing-side Band part 3, an ax arm 4, also as a clutch claw designated coupling part 5 and a Insert 6 on which the drive rod 2 is displaceable can be led. The insert 6 serves to attach the side fitting 1 in a Wing of the window provided circumferential groove in the the drive rod 2 can also lie.

The wing-side hinge part 3 has a bearing sleeve 7, from which an arm-shaped boom 8 extends, which is made radially from the bearing sleeve 7 outgoing first section 9 and one itself adjoining second section 10, the first section 9 being approximately tangential extends from the outer surface of the bearing sleeve 7. The second section 10 forms with the first Section 9 a right angle. In each Edge area of the narrow sides of the second section 10 fastening means 11 and 12 are provided, which are realized as openings 13. About in the middle between the two fastening means 11 and 12 an axis of rotation receptacle 14 formed, which also is realized as a breakthrough.

The arm 4 is an elongated leg 15 realized, which has an offset 16 approximately in the middle. At its end 17 facing the band part 3 the arm 4 also has an axis of rotation receptacle 18 formed by a breakthrough is. At its other end 19 is a breakthrough 20 (Figure 6) provided.

The coupling part 5 is U-shaped in cross section trained so that between the two legs 21 and 22 of the U's of the arm 4 partially added can be. Are on the upper leg 21 in the picture Breakthroughs 23 provided with breakthroughs 24 (Figure 6) are aligned, which are provided on the lower leg 22 are. Breakthroughs 23 and 24 are here each formed as a row of holes, the openings 23 and 24 spaced apart form the respective row of holes. The one at the bottom Leg 22 present outer openings 24th serve as fasteners 25 and 26, whereupon is discussed below.

The two legs 21 and 22 of the coupling part 5 are spaced by the length of the base 27 of the U's and preferably parallel to each other, wherein the distance between the two legs 21 and 22 so is chosen that the ax arm 4 with preferably low Game between the two legs 21 and 22 fits.

On the lower leg 22 are outside on the narrow sides Latching means 28 provided with the insert 6 trained locking means 29 cooperate. The locking means 28 are realized as a recess, the locking means 29 as knobs or as projections.

At the lower leg 22 of the coupling part 5 is introduced a partial elongated hole 30, which is extends between the two openings 24, however does not merge into the openings 24.

The insert 6 has a base 31, the Length approximately the longitudinal extent of the coupling part 5 corresponds. In the base 31 is a partial elongated hole 32 provided, which is between fasteners 33 and 34 extends in the present Embodiment designed as threaded holes are. The locking means 29, the fasteners 33 and 34 and the partial elongated hole 32 are preferably in a row, with the outside Locking means 29 a greater distance from each other have as the fastening means 33 and 34 to each other. The partial elongated hole provided on insert 6 32 and that provided on the coupling part 5 Partial slot 30 are preferably in terms of their Length and width are identical and lie so in the coupling part 5 or insert 6 that they rest on the insert 6 Coupling part 5 are aligned or are congruent.

On the side 35 of the insert facing away from the band part 3 6, the base 31 goes into step 36 a clamping means receptacle 37. In the clamping device holder 37 are provided clamping means 38 which trained in the present example as grub screws are. They are used in the circumferential groove of the wing insert 6 with the wing to jam so that the insert 6 and so that the side fitting 1 securely in the circumferential groove being held. The insert is also located 6 - seen in cross section - such as Profile before that between the circumferential groove and insert 6 a rear grip is formed. Thereby the insert 6 is secure in the circumferential groove held, the clamping means 38 a longitudinal displacement of the insert 6 in the circumferential groove prevent.

The side fitting 1 is also a locking device 39 assigned, which as a fork-shaped receptacle 40 is formed, which is from the insert 6 opens away. At the closing means 39 is still a fastener 41 formed as a threaded hole is realized. Furthermore, the Closing means 39 has a recess that is open in some areas 42 in which the end 17 of the ax arm is insertable. In the area of the recess 42 a rotary axis recording realized as a breakthrough 43 trained.

The drive rod 2 that can be assigned to the side fitting 1 points at its one, the end 17 of the ax arm adjacent At the end 44 of a counter-locking device 45, which is preferably designed as a mushroom cone which, in addition to the hat 46, also has a ring collar 47 may have, wherein the hat 46 and the ring collar 47 - seen in the axial extension of the mushroom pin Distance from each other. This distance corresponds approximately to the thickness D of the fork-shaped receptacle 40, the between the hat 46 and the Ring collar 47 present area of the mushroom pin has an outer diameter that the opening width W corresponds to the recording 40.

At a short distance from the end 44 the Driving rod 2 has an offset 48, one further offset 49 at the other end 50 of the Driving rod 2 is present. Between the two offsets 48 and 49, the drive rod has 2 guide slots 51 and 52, into the guide elements 53 (Figure 4) engage the rear 54 of the Base 31 of the insert 6 are provided.

The drive rod has at both ends 44 and 50 Coupling devices 55 with which the drive rod 2 to the rest of the drive rod gearbox (not shown) of the wing can be coupled, whereby the drive rod 2, for example, via an operating handle is drivable.

With the help of Figures 2 to 5 it is described how the components of the side fitting 1, i.e. the hinge part 3, the arm 4, the coupling part 5 and that Insert 6, are connected together and how the connecting rod 2 is articulated on the side fitting 1 is:

An axis of rotation 56 extends through the axis of rotation receptacle 43 on the locking means 39, the axis of rotation 18 at the end 17 of the arm 4 and the axis of rotation 14 on the belt part 3. The axis of rotation 56 is preferably designed and has a thru axle a stop 57 on the in the shooting. 14, 18 and 43 inserted axis of rotation 56 for example comes to rest on the closing means 39 or with a small distance to the locking device 39 lies. After the axis of rotation 56 through the Rotary axis recordings 14, 18 and 43 is inserted provided that their free, the stop 57 opposite End 58 is expanded so that a Falling out of the axis of rotation 56 is avoided. The Rotation axis 56 enables a pivoting movement of the Band part 3 with respect to the arm 4, whereby by a fastening element, not shown here, which is the fastener 11 and the fastener 41 reaches through, a firm connection made between band part 3 and locking means 39 is. Thus, the band part 3 and that Closing means 39 is pivotable with respect to the arm 4 be moved. The band part 3 and that Locking means 39 are therefore with a screw connection can be coupled together.

The coupling part 5 is at least one Screw connection can be fixed on the insert 6. The screw connection comprises a fastening element, which by one of the outside Breakthroughs 23 can be passed so that it one of the openings 24 and the fastener 33 or 34 reaches through. For pre-fixing the coupling part 5 on the insert 6 are as above mentioned - the locking means 28 on the coupling part 5 and the locking means 29 provided on the insert 6.

A pin 59 extends from the end 19 of the arm 4 (Figure 6), which is perpendicular to the longitudinal extension of the ax arm extends. The pin 59 passes through the partial elongated hole 30 in the lower leg 22 of the coupling part 5 and reaches through the other Partial slot 32 of the insert 6. At its free end, which is on the back 54 of the base 31, the pin 5 has a thickening, over the boundary edge of the partial elongated hole 32 survives. The pin 59 is also on the arm 4 kept captive. The arm 4 lies between the legs 21 and 22 of the coupling part 5. means of the pin 59 and the overlapping Partial elongated holes 30 and 32, which form an elongated hole L form, is a slewing ring X between the arm 4 and insert 6 realized so that the Ax arm with respect to the insert 6 and the coupling part 5 can be moved longitudinally and swiveled is led. The fact that the pin 59 in Ax arm 4 held captive and at its free Axer arm are thickened at the end 4, the insert 6 and the coupling part 5 captive connected with each other.

Through this rotary connection X, the arm 4 in be brought out as in Figure 3 is shown. This fold-out position of the Axer arm 4 is the tilt opening position of the wing assigned to the window. The unfolded position of the Axerarms 4 can be taken when the Driving rod 2 with its counter-closing means 45 the fork of the closing means 39 in the direction of the arrow 60 is extended, as shown in Figure 2 is, which is shown that the pin 59 rotated in the elongated hole L and the band part 3 together with the closing means 39 about the axis of rotation 56 is rotated, as indicated by arrows P. is. This creates the rigid connection between Insert piece 6 and the band part 3 canceled, wherein this rigid connection through the connecting rod 2 is realized when the counter closing means 45 in the fork of the closing means 39 engages.

The longitudinally displaceable guide of the drive rod 2 is achieved in that on the back 54 of the Insert 6 a guide groove 61 is provided, in which the drive rod 2 is longitudinally displaceable. In addition, the drive rod 2 through the guide elements 53 led into the guide slots 51 and 52 intervene. The leadership elements 53 are formed by ring collars 62 which their inner walls each have a thread of the fasteners 33 and 34 have. Through the guide slots, that of the guide elements 53 be penetrated, or by the Length of the guide slots 51 and 52 is also a travel limit of the drive rod is formed.

For the turning opening position of the wing, the Drive rod 2 moves in the opposite direction of arrow 60, so that the counter locking means 45 in the fork of the closing means 39 engages. Because the Driving rod on the rear 54 of the insert 6 is only kept longitudinally displaceable the aforementioned rigid connection between Insert 6 and wing-side hinge part 3 formed so that the window sash around his Rotation opening axis, which encompassed by the bearing sleeve 7 becomes flexible.

From Figure 5 it is particularly clear that the ax arm 4 between the two legs 21 and 22 of the Coupling part 5 is held with little play. The coupling part 5 is used in particular to Rotary connection X on the pin 59, which in the partial elongated holes 30 and 32 intervenes to relieve. In particular when the window sash is in the open position are with the coupling part 5 on the ax arm 4 acting bending moments intercepted by the weight of the window sash result. How can also be seen from Figure 5, does that Coupling part 5 still has the function of guiding the Axer arm 4 when moving the window sash in Tilt position.

If the side fitting 1 is on another stop side are changed as follows:

The screw connection between coupling part 5 and Insert 6 is released, causing a pivoting movement of the coupling part 5 relative to the insert 6 is possible, as shown in Figure 6 is. Starting from FIG. 2, FIG the coupling part 5 is pivoted counterclockwise as indicated by an arrow 63 is. Around the side fitting 1 for the other To prepare the stop side completely the arm 4 in alignment with the Drive rod 2 brought and then the coupling part 5 pivoted further in the direction of arrow 63, until its longitudinal extent again with the longitudinal extent of insert 6 coincides. there engage the locking means 28 and 29 again, so that the screw connection between coupling part 5 and Insert 6 can be easily carried out means that the screw of the screw connection in fasteners 25 or 26 and 33 or 34 can be introduced. For the complete switchover then on the other side still loosened the screw connection that the fasteners 11 and 41 passes through, so that the band part 3 counterclockwise (arrow 63) Can be turned 180 °. Then through the fastener 12 passed a screw again and screwed to the fastener 41, so that the fixed coupling between band part 3 and locking means 39 is restored. It can be seen, therefore, that without disassembling the Side fitting 1- a stop side change is possible, only screw connections solved, the coupling part 5 and the band part 3 one position rotated by 180 ° into its other position and then the corresponding screw connections need to be restored. It would also be conceivable that the stop page change of the side fitting 1 can then also be carried out is when the side fitting 1 is already on the casement is arranged. For example, this may be necessary be wrong if one is on Side fitting aligned to the left a sash frame intended for right hinging has been assembled.

The side fitting 1 according to the invention stands out So in that the ax arm 4 by means of Pin 59 compared to the insert 6 and the Coupling part 5 rotatably and longitudinally articulated and moreover captive to it is coupled to both parts. Also draws the side fitting 1 characterized in that the Coupling part with respect to its transverse central axis 64 is mirror-symmetrical, the Mirror symmetry especially on the fasteners 25 and 26 and on the locking means 28 and the partial elongated hole 30 relates.

From Figure 6 it can still be seen that the Driving rod 2 with counter locking means 45, the insert 6, the arm 4 and the closing means 39 mirror-symmetrical with respect to their longitudinal center axis are designed so that for a stop page switching no parts exchanged, just the band part 3 and the coupling part 5 by 180 ° have to be pivoted.
