Kniehebel-Stulp" bereits in der Zeitschrift Baubeschlag-Magazin", 29. Jahrgang, Heft 7/1981, auf Seite 106 vorgestellt worden. Seine baulichen Einzelheiten waren zuvor durch Ausstellung auf der Veranstaltung Fensterbau 81" in Stuttgart vom 12. - 14. Juni 1981 bekannt geworden. A rebate lever gearbox to determine the underlapping sash of double-leaf windows or doors without a frame intermediate post is under the name

Toggle lever cuff "already in the magazine Baubeschlag-Magazin ", 29th year, issue 7/1981, on page 106. Its structural details had previously been shown at the event Fensterbau 81 "in Stuttgart from June 12th to 14th, 1981.

These known folding lever gears are a so-called Cuff rail drive rod fitting assigned, in which the Push rods on the back of a faceplate are guided longitudinally. With the help of the faceplate the rebate lever gears are in a stepped groove - the so-called EURO groove - on the circumferential surface of a fold Wood or plastic wing struck.

For a two-wing installation on the underlapping wing Windows or doors with no frame mullions coming out Metal and / or plastic hollow profiles with C-shaped or profiled dovetail undercuts Drive rod guide channels are provided, are suitable previously known folding lever gears not easily. There namely the C-shaped or dovetail-like undercut profiled drive rod guide channels different hollow profiles more or less different cross-sectional shape and also different Can have dimensions, at least the Stop plate of the rebate lever gear on it resulting, different installation situations will. Therefore, it has been common for the latter Purpose of folding lever gear with accordingly to produce differently designed stop plates and ready.

The aim of the invention is therefore a simple way show that makes it possible to use the same design a folding lever gear for a variety of metal and / or Plastic hollow profiles built windows or doors harness, even if they differ designed and / or sized, C-shaped or profiled dovetail undercuts Espagnolette guide channels are equipped.

• einen vor einen C-förmig oder schwalbenschwanzartig hinterschnitten profilierten und einen Öffnungsspalt aufweisenden Längskanal von Metall- und/oder Kunststoff-Hohlprofilen setzbaren sowie darin lagenfixierbaren Adapterkörper,
  und dadurch
• daß in diesen Adapterkörper die Anschlagplatte einsetzbar sowie darin zumindest über ihre beiden Enden - durch Verriegeln - festlegbar ist,
• wobei der Adapterkörper mit dem Öffnungsspalt des Längskanals der Hohlprofile zugewendeten Durchlässen für die beiden Kupplungszapfen versehen ist.

The solution proposed according to the invention for solving the aforementioned object is characterized by

• an adapter body which can be placed in front of a C-shaped or dovetail-shaped undercut and has an opening gap and has a longitudinal channel of hollow metal and / or plastic hollow profiles,
  and thereby
• that the stop plate can be inserted into this adapter body and can be fixed in it at least over its two ends by locking,
• wherein the adapter body is provided with the opening of the longitudinal channel of the hollow profiles facing passages for the two coupling pins.

According to the invention, it has proven itself if the Adapter body is designed essentially frame-like and has anchoring elements on its underside which are made by the opening gap in the undercut areas of the Longitudinal channel on the hollow profile can be engaged while he on the top carries bolt attachments, behind which on the Stop plate trained counter-bolt elements hook-like are indentable.

It is advantageous that one and the same Adapter body easily with metal and / or plastic hollow profiles can be brought into connection with more or less differently designed, C-shaped or profiled dovetail undercuts Longitudinal channels are equipped. With this adapter body on the other hand, a folding lever mechanism in operative connection brought that in a very specific way designed stop plate is provided.

The assigned to the two ends of the stop plate Latch approaches of the adapter body can be advantageous Way provided by one on its transverse edges Toothing, in particular a rectangular toothing formed be, while the counter-locking elements of the stop plate End notches are one for interlocking have complementary edge course. Here is the transverse edge toothing of the adapter body around the thickness of the adapter plate above its support or support surface for the Stop plate located and the arrangement of the transverse edge toothing on the adapter body is asymmetrical Main longitudinal plane provided, while the end notches of the Stop plate one with respect to its longitudinal median plane have a symmetrical design.

On the basis of these training measures all components and functional parts of the folding lever mechanism in one use longitudinally symmetrical design that easily installation in windows on the right as well as on the left and doors. On the other hand, the adapter body can too a transverse plane can be designed symmetrically, so that he too simply by rotating 180 ° parallel to or on its mounting level for right and left hinged Windows and doors can be used.

According to the invention it is also provided that the Stop plate between the two elongated guide holes for the coupling pin as an additional counter-locking element has bent backwards bow while on Adapter body as an associated bolt attachment one of one Tongue protruding towards the longitudinal center is located, under which the bracket can be inserted sideways. The Retaining connection between the stop plate of the rebate lever gear and the adapter body is through this Measure significantly improved.

According to the invention, there is an important further training measure also in that the passages in the adapter body one each unilaterally against the course of the elongated holes in the Stop plate have inclined edge boundary and that this Edge limitation the coupling pin for the drive rods as Control edge for a forced locking of the Stop plate is assigned to the adapter body. The order the inclined edge limits for the passages in the Adapter body has therefore been made so that Adjust the locking position for the coupling pins the connecting rods on the stop plate of the rebate lever gear through this also the forced engagement of the Locking the stop plate on the adapter body causes.

For the correct insertion of the stop plate of the rebate lever gear in this case it is in the adapter body first required, its operating lever and its Handlebar in the swung out opposite the stop plate Able to bring in so that both connecting rod coupling pins their corresponding to the unlocking position of the drive rods Relative position to the elongated holes of the stop plate. Now the stop plate with your Counter-bolt elements on the bolt attachments of the adapter body sink into the adapter body. Then be Actuating lever and handlebar of the folding lever mechanism in the Set parallel position back to the stop plate, then move the led in the elongated holes of the stop plate Coupling pins in their locking position for the Position corresponding to the driving rods. You run to the inclined edge boundaries of the passages in the adapter body along and thereby force the hook-like indentation of the Stop plate with its counter bolt elements behind the Latch approaches of the adapter body.

Adapter body and rebate lever gear can now be used together or with each other on the window or door wing in front of the C-shaped or profiled dovetail undercuts Longitudinal channel set and through its opening gap over the Coupling pin in operative connection with the drive rods to be brought. At the same time they come Anchoring elements of the adapter body through the Opening gap in the undercut areas of the Longitudinal channel for engagement and can be properly there position fix.

The invention provides that the anchoring elements of the Adapter body on the one hand from an undercut area of the longitudinal channel under the fixed hook feet are formed and on the other hand in their neighborhood adjustable pressure screws, which are made with its free, preferably pointed end - obliquely - under the other undercut area of the longitudinal channel can be placed are.

A folding lever mechanism further developed according to the invention is particularly advantageous for installation in metal and / or Plastic hollow profiles with two in different levels one above the other, C-shaped or profiled dovetail undercuts Longitudinal channels are provided, each with an opening gap have and of which the longitudinal channel in the lower level forms a drive rod guide channel. In this case it is it is important that the coupling pins for the drive rods over the back of the adapter body into the drive rod guide channel of the hollow profile and there in a coupling hole protrude into the drive rod.

In the drawing is a so-called folding lever gear 1 for the actuation of espagnolette fittings shown in the failing wing of double-leaf windows or doors installed without a frame intermediate post, i.e. with so-called French sash windows or doors are required.

Such a folding lever mechanism 1 is with two oppositely adjustable coupling pins 2 and 3 for one each longitudinally guided drive rod 32 equipped Arrangement in the hollow hollow profile 16 and mode of operation will be explained later in another place. Of the Coupling pin 2 is in a slot 4 and the Coupling pin 3 is in a slot 5 transverse to it Axially slidably guided, both elongated holes 4th and 5 at a distance from each other but rectified in one Stop plate 6 are.

The coupling pin 2 is of one arm Actuating lever 7 worn and at the same time forms it extending transversely to the stop plate 6 bearing axis. At the Coupling pin 3 engages a handlebar 8 with one end on, such that the coupling pin 3 at the same time transversely to the stop plate 6 directed bearing axis. The other The end of the handlebar 8 is at a distance via a pivot pin 9 of the coupling pin 2, which also acts as a bearing axis the operating lever 7 connected. The handlebar 8 with the Coupling pin 3 and that from the coupling pin 2 to Link pin 9-reaching section of the actuating lever 7 act as carried by the stop plate 6 Toggle lever together.

If the folding lever gear 1 in its Figs. 1 and 3 of the Drawing corresponding swivel position of operating lever 7 and handlebar 8 - ie in the knee position of the toggle lever is, its two coupling pins 2 and 3 are in the area of the two mutually facing ends of the elongated holes 4 and 5 pushed in the stop plate. This setting of the folding lever gear 1 corresponds to the unlocking switch position for the coupling pins 2 and 3 longitudinally displaced drive rods 32.

Since the operating handle 7 and the handlebar 8 of the folding lever mechanism 1 - as already mentioned above - according to Art a toggle lever work together, the two Coupling pins 2 and 3 relative to the stop plate 6 in the Area of the opposite ends of both elongated holes 4 and 5 pushed when operating lever 7 and handlebar 8 out its pivoting position (FIGS. 1 and 3) into that of FIG. 5 removable parallel position can be swiveled in. It occurs thereby namely an extended position of the two Coupling pins 2 and 3 on the operating lever 7 and on the handlebar 8 and the pivot pin 9 between the actuating lever 7 and Handlebar 8 certain toggle lever relative to the stop plate 6 a.

The smallest distance 10 between those in the elongated holes 4 and 5 of the stop plate 6 guided coupling pins 2 and 3 1 to 4 of the drawing can be seen while you greatest distance 11 from one another in FIGS. 5 to 7 is.

So that the folding lever gear 1 in one and the same Execution both on the right-hinged window or Door leaves as well as on window hinges hinged on the left Lets use door leaves, his operating lever 7 is too a longitudinal center plane 12-12 is symmetrical; his handlebar 8 is to a longitudinal median plane 13-13 designed surface symmetrical and has its stop plate 6 a surface-symmetrical to a longitudinal center plane 14-14 Shape, particularly as shown in FIGS. 1 and 3 of the drawing reveal.

From the symmetrical and neutral locking switch position of the folding lever gear 1 according to FIG. 5 actuation lever 7 and handlebar 8 relative to Stop plate 6 optionally on one side or the other swing out. As a result, the folding lever gear 1 together with a window or hinged on the right Door wing as well as left together with one Use the hinged window or door sash.

The peculiarity of the folding lever mechanism explained above 1 is that its stop plate 6th cooperate with a special adapter body 15 and in Active connection can be brought. This for the purpose of Rebate lever gear 1 for such misleading wings double-leaf windows or doors without intermediate frames to make usable, made of metal and / or plastic hollow profiles 16 are built. Such metal and or Hollow plastic profiles 16 usually have the accommodation of the longitudinally sliding drive rods 32 of their Espagnolette fittings in the area of their rebate surface 17 at least one C-shaped or dovetail-like undercut profiled longitudinal channel 18a or 18b each have a longitudinal opening gap 19a and 19b on.

The purpose of the adapter body 15 is one and the same Folding lever gear 1 through its stop plate 6 assign the hollow profiles 16 without problems can if their longitudinal channels 18a and 18b and Opening gaps 19a and 19b a different or have different configurations, such as the Case is

The adapter body 15 is used as a carrier for the Stop plate 6 in front of one of the C-shaped or dovetailed undercuts and the Longitudinal channel 18a or 19b with opening gap 19a or 19b 18b set, as clearly shown in FIGS. 10 to 14 of the Drawing can be taken. The can Adapter body 15, for example, in the longitudinal channel 18a behind it Fix the opening gap 19a securely, like that again 11 to 14 of the drawing can be seen and will be explained in more detail below.

The adapter body 15 has a receptacle 20 in which the Stop plate 6 of the folding lever gear 1 can be used. On the one hand, the receptacle 20 of the adapter body 15 has this and on the other hand the stop plate 6 of the folding lever mechanism 1 an embodiment which is a simple definition of Stop plate 6 by locking at least over their two Ends. In addition, the adapter body 15 is included the opening gap 19a of the longitudinal channel 18a facing Passages 21 provided. These allow access to the Coupling pins 2 and 3 of the rebate lever gear through the Opening gap 19a in the longitudinal channel 18a and possibly also through the opening gap 19b in the ones below Longitudinal channel 18b of the hollow profile 16 to there with the Interacting rods 32 of the connecting rod fitting.

1 of the drawing shows that the Adapter body 15 at least in the area of its receptacle 20 for the stop plate 6 of the folding lever mechanism 1 in essentially has the shape of a frame 22. Furthermore but is apparent from FIGS. 2, 4, 6 and 10 to 14 that the Adapter body 15 on its underside with special Anchoring elements 23 and 24 is provided. With their help he can through the opening gap 19a in the Undercut areas of the longitudinal channel 18a indented and then securely fixed in position there.

The adapter body 15 has the anchoring elements 23 on the one hand, fixed molded hook feet, which are under indent an undercut area of the longitudinal channel 18a to let. On the other hand, there are its anchoring elements 24 from pressure screws in the vicinity of the hook feet through the adapter body 15 inclined internal threads 25 are held. With their free, preferably pointed ends, these pressure screws, for example by turning it with a wrench, in their longitudinal direction among the others Undercut area of the longitudinal channel 18a set, such as 13 and 14 clearly shows.

The folding lever mechanism 1 can also have its stop plate 6 the adapter body 15 are brought together before this then on the one hand over his designed as hook feet Anchoring elements 23 and on the other hand via its Anchoring elements 24 formed on pressure screws Hollow profile 16 in front of the opening gap 19a of the longitudinal channel 18a is set. For this, the entire rebate lever gearbox must first be used 1 relative to the adapter body 15 in the from 3 and 4 apparent relative position are brought. For this the stop plate 6 of the folding lever mechanism 1 from above into the receptacle 20 delimited by the frame 22 of the adapter body 15 lowered until it is the one Contact surface 26 containing passages 21 meets. For that is it is important that the adapter body 15 on both transverse edges its frame 22 with at least the material thickness of the Stop plate 6 corresponding distance above the Support surface 26 bolt projections 27 carries. Behind these can formed at the two ends of the stop plate 6 Counter-locking elements 28 are brought to the holding engagement can. 1, 3 and 5 of the drawing can be seen that the locking lugs 27 of the adapter body 15 each of one provided on the transverse edges of the frame 22 Toothing, namely a rectangular toothing with two each Teeth and two tooth gaps are formed. Their arrangement is taken so that the one longitudinal limitation of the Frame 22 has a tooth gap and the other longitudinal limit of the Frame is adjacent to a tooth. The counter-locking elements 28 on the stop plate 6 are provided by End notches formed. This results in the Stop plate 6 for the transverse edge toothing of Adapter body 15 complementary edge course with two teeth and a tooth gap. While the arrangement of the as Bolt approaches 27 effective cross-edge toothing of Adapter body 15 asymmetrical to the main longitudinal plane is provided by the end notches of the Stop plate 6 one with respect to the longitudinal center plane 14-14 Get symmetrical design of the counter-bolt elements 28.

After the stop plate 12 of the folding lever gear 1 with their counter-locking elements 28 on the locking lugs 27 of the Adapter body 15 over in the receptacle 20 or the frame 22 is brought down to the contact surface 26 (see FIG. 3 and 4) it can be moved along this contact surface 26 move sideways. This will then be the bolt approaches 27 of the adapter body 15 of the counter-locking elements 28 of the Raised under the stop plate 6. Hence the Stop plate 6 in the receptacle 20 or the frame 22 of the Adapter body 15 set easily.

At this point it is pointed out that the Stop plate 6 of the folding lever gear 1 between them two guide slots 4 and 5 for the coupling pin 2 and 3 as an additional counter-locking element can have backwards bent bow 29, the can be seen in particular in FIGS. 1, 3, 4, 7 and 9. On the other hand, the adapter body 15 has an associated one Latch projection 30 one from a longitudinal edge of the frame 22 tongue protruding towards the longitudinal center, under which the bracket 29 engages sideways as soon as the stop plate 6 from the position according to FIG. 3 into the position according to FIG. 5 is moved. The engagement position of the tongue Latch 30 relative to the bracket 29 is also clearly in Fig. 9 of the drawing can be seen.

Special precautions have been taken on the adapter body 15, through which the positive engagement position of the stop plate 6 in its receptacle 20 or in its frame 22 on simple Way can be secured. Because they have the passages 21 on one side in the support surface 26 of the adapter body 15 one against the course of the elongated holes 4 and 5 in the Stop plate 6 inclined edge boundary 31 the coupling pins 2 provided on the folding lever mechanism 1 and 3 interact for the drive rods. As soon as that Folding lever gear 1 from its swung out Unlocking switch position (Fig. 1 and 3) in his pivoted locking switch position (Fig. 5) brought the inclined edge boundaries 31 of the passages act 21 as control edges with the coupling pins 2 and 3 in one Way together for a forced locking the stop plate 6 in the adapter body 15 provides. In the pivoted locking switch position of the folding lever gear 1 is the stop plate 6 of the folding lever mechanism 1 in a form-fitting manner in the adapter body 15 locked. Fold lever gear 1 and adapter body 15 can so together or as a unit for attachment to respective wing and for the coupling with the inside guided drive rods 32 are handled.

Since the coupling pins 2 and 3 of the rebate lever gear 1 each with their cross-section adapted openings in the Espagnolette 32 of the espagnolette fittings in operative connection occur, the positive locking of the Stop plate 6 of the folding lever gear 1 against unwanted Side shift relative to the adapter body 15 even then permanently ensured if the rebate lever gear 1 between its pivoted unlocking switch position and its pivoted locking switch position is switched.

In conclusion, only for the sake of completeness be noted that according to FIGS. 10 to 14 of the drawing by the adapter body 15 on a hollow profile 16 anchored rabbet lever gear 1 via its coupling pin 2 and 3 is coupled with drive rods 32, which in the lower Longitudinal channel 18b of the hollow profile 16 are guided. The coupling pins 2 and 3 therefore reach through there Opening gap 19a and the adjoining longitudinal channel 18a as well as the opening gap 19a below into the Longitudinal channel 19b into it.

Of course, you can use to define the Adapter body 15 on the rabbet surface 17 of hollow profiles 16 necessary anchoring elements 23 and 24, for example the hook feet and the pressure screws, also in places provide that are within that length range are, which by the small distance 10 between the two coupling pins 2 and 3 of the folding lever mechanism 1 is limited. Such an embodiment of the adapter body 15 then makes it possible to also use the folding lever mechanism 1 used for the construction of window and door sashes Assign hollow profiles 16, the 17 on their fold surface only are provided with a longitudinal channel 18a, which in addition to the longitudinally guided drive rods 32 also Anchoring means for the proper attachment of the Rebate lever gear 1 must take up.

From Fig. 1 of the drawing it can still be seen that it It is expedient, the adapter body 15 to a transverse plane 33-33 give symmetrical design. Out of this namely results in the advantageous possibility that the Adapter body 15 by simply turning it through 180 ° parallel to or on its mounting level for both right as well as for left hinged windows and doors lets use.
