Description

From the DE 8316991 U1 is an espagnolette fitting known which has a locking pin at a closing point, which engages in the locking position of the espagnolette fitting a retaining shoulder of a striker. Upon actuation out of the locking position of the locking pin is displaced along the Flügelfalzes and hits in the gap ventilation position on a relation to the retaining shoulder falzauswärts directed, inclined bevel, which urges the locking pin falzauswärts together with the wing. Finally, the locking pin engages behind a limited movable and falzeinwärts by a spring kraftbeaufschlagte catching shoulder, which limits the maximum Ausstellweite of the locking pin. The wing pivots about a hinges forming by a vertical axis. The maximum Abstellweite results from the distance of the locking pin and the catching shoulder of the pivot axis.

A disadvantage is that the Ausstellweite is fixed and the gap ventilation position is secured only by the rear grip of the locking pin of a catching shoulder. All other locking pins must be moved out of the locking position with this concept, so that the Abstellweite can be taken without compulsion.

This approach is also the DE 3041399 A1 underlying, in which the retaining pin as a special holding element also requires a special component.

The DE 102012218887 B4 discloses a striking plate for an espagnolette in which the retaining shoulder for a closed position and the retaining shoulder for a gap ventilation position offset in the longitudinal direction of the fold. So that in the night ventilation position of the locking pin and the wings are urged out of falzauswärts, the closing slot approaches the inwardly located longitudinal edge of the striking plate, so that only a thin-walled web remains. According to the rigid spacing of the retaining shoulders, the locking pins of all remaining striking plates must be moved out of the retaining shoulders in order to avoid being forced out of the fold.

A similar structure shows the DE 19929818 A1 ,

In the DE 3043925 A1 all striker plates are identically designed to achieve a parallel Abstellweite the wing to the frame. For this purpose, the hinge elements connecting the wing to the frame are also matched to the parking movement. This requires in addition to the additional hinge elements, which have only limited capacity due to the moving components, the use of special strike plates.

From the EP 1422372 A1 is one of the DE 3043925 A1 corresponding concept known.

The EP 1582673 B1 discloses a strike plate with a rigid slotted guide, in which a locking bar is movable. The arrangement causes an adaptation of the locking bar to the Abstellbewegung the pin. However, since the slotted guide is rigid, no arrangement of several strike plates at different distances from the pivot axis of the wing can take place, since the closer to the pivot axis located strike plates cause a larger swing angle than remotely mounted strike plates.

The EP 1568833 A2 discloses strike plates, which consist of a base body, as well as a movable bar body. The locking body has a Z-shaped locking slot with two mutually offset locking shoulders, and a transverse to the rebate adjustment channel. The adjustment channel is open edge-open and associated with a wing-side adjusting element, which should reach a defined position assignment of the locking body to the locking pin when entering the adjustment channel. In addition to the elaborate design, the achievable safety is limited in this case by only one locking pin in the gap opening position.

The EP 1 568 833 A2 and the EP 1 816 292 disclose a generic espagnolette fitting according to the preamble of claim 1.

From the EP 1568833 A2 a strike plate is known, the backdrop-shaped closing slot is arranged in a plate body arranged displaceably along the fold. The sheet metal body can be aligned via a wing side mounted on an espagnolette fitting Justierzapfen, so that when closing the wing by means of the Justierzapfens a relative position correction of the closing slot and the espagnolette fitting takes place. It results from the engagement of the adjusting pin an immovable position of the sheet metal body. The to DE 8316991 U1 mentioned disadvantages also occur here and it is expensive to design all striking plates in this way.

The concept of EP 1 816 292 A2 provides a strike plate, which is movable in total perpendicular to the frame plane. As a result, the locking slot acted upon by the locking pin is also moved along in the locking position, with the result that the striking plate can not fulfill its original function of pressing the wing closely against the frame. For this reason, an actuator is provided which displaces the strike plate correspondingly for a displacement of the closing slot.

The known embodiments is so common that either only a single locking pin causes only limited secure locking, or the overall fitting must allow a parallel setting, in which the hinges must be specially equipped.

The invention has for its object to eliminate the disadvantages of the prior art.

The invention provides for a generic espagnolette fitting that the ramp is mounted on a mounted below a closing slot forming the cover plate and that in the gap ventilation position (III) of the retaining pin is associated with a movable relative to the closing slot locking slot portion. With the adjustable bevel an adjustable Abstellweite the affected striking plate is achieved. In this case, the ramp is formed of a below the closing slot forming cover plate mounted adjusting member, so that the strike plate consists of few parts and in the gap ventilation position of the retaining pin is associated with a locking slot relative to the locking slot portion, so that move the retaining pin falzauswärts together with the slot portion can. This makes it possible to provide a plurality of similar built-lock plates on a window or a door whose Abstellweite is set in dependence on the distance to the pivot axis of the wing. Since all these striking plates have identical switching sequences, a greater number of engaged locking pins also result in the night ventilation position, which leads to increased safety even with a gap-open wing. The design of the retaining pin as a locking pin also allows retrofitting an existing espagnolette fitting, in which the existing strike plates are replaced on the vertical and the upper horizontal frame legs by the striking plates according to the invention.

It is provided that the movable bolt slot portion is arranged in a, a fastening portion superior carriage.

In order to guide the carriage optimally, it is provided that the striking plate at the longitudinal ends of a, the closing slot and the movable carriage in the longitudinal embracing collar has, which also improves the appearance and sharp-edged projections are avoided.

In order to be able to apply a particularly high resistance, provision is made for the movable locking slot section to be arranged on a pivotable lever.

In this case, it is also provided that the lever is connected to the strike plate by means of a rivet which forms the axis of rotation and by a head rivet which passes through it radially.

In order to achieve a defined depending on the installation location setting is provided that the casserole has an adjustable in several stages relative to the stationary sheet metal pin.

The burglar resistance is maximized when the locking pin is a mushroom pin, whose waisted shaft is tuned with little play on the closing slot width in the carriage.

A equipped with a espagnolette fitting window or door provides with safety advantage that identical identical strike plates are attached to at least three side rails.

If the espagnolette fitting comprises an opening device for a tilt-and-turn switching position, then this switching position is set up as a gap-tilting position by the arrangement according to the invention, since the locking pin lies opposite the locking points in this switching position.

At the window after Fig. 1 the frame 1 and the wing 2 via a scissors bearing 3 and a corner band 4 is connected to each other. The scissor bearing 3 and the corner band 4 form a lateral vertical pivot axis 5. The scissors bearing 3 is coupled to a release device, which is not visible here. Via a hand lever 6 and a coupled drive rod drive, which is mounted in the sash, various operating conditions can be set. In the locking position I, the wing 2 is locked. In this switching position attached to the espagnolette latch pin are moved so that they occupy a first end position within a closing slot and grapple a retaining shoulder. In the rotational opening position denoted by II, the wing 2 is rotatably open and the locking pins take a mean of three possible Schlaltpositionen, so that the locking pins reach an open-edge region of the closing slot and can be moved out of the closing slot. The wing 2 can be pivoted about the vertical pivot axis 5. The third shift position is a night ventilation position III. The locking pin is moved in one of the locking position I opposite direction. In this switching position, a tilt lock is activated on the lower horizontal frame member 7 and at the same time a mounted on the upper horizontal wing spar 8 raising device, which is coupled to the scissors bearing 3, released. As far as it concerns a fog-equipped with a standard espagnolette wings, this can now be pivoted about a lower horizontal axis 9 and the pivot angle is limited by the Ausstellvorrichtung.

In the illustrated embodiment, however, the strike plates are corresponding to the in FIGS. 2 and 3 formed locking plate 10 is formed. This has a Z-shaped profile of a closing slot 11 which is limited in the first locking position I falzauswärts in the direction of the arrow 12 and in the folding longitudinal direction 12b extending through a retaining shoulder 13. In the, in Fig. 2 indicated a locking pin in the region of a lateral opening 14. A previously captured in the closing slot 11 locking pin can pass through the opening 14 when the wing 2 is pivoted about the pivot axis 5. While in a first section 15 of the closing slot 11, this runs parallel to the fold, a section 16 is designed to be inclined. This is followed by a second falzparalleler latch slot portion 17 connects. The thus divided into three sections 15, 16 and 17 latch slot 11 consists on the one hand of the running in a cover plate 18 contour and the other from a mounted below the cover plate 18 guide rail 19. The guide rail 19 is part of a lower part 20, which in the Fig. 4 is shown as a single part. The interaction of the locking pin with the guide bar is in the EP 1208281 B1 to which reference is made in full. In accordance with the locking fitting disclosed therein, a locking pin shaped as a mushroom-headed pin is supported with respect to a waisted shaft enlarged diameter head 29 on the Führungsleiste19, so that the shaft remains initially spaced from the cover plate.

Evidently the Fig. 4 joins the section 15 of the inclined portion 16 at. The section 16 is a ramp 21 for the locking pin and is part of a setting piece 22. The adjusting piece 22 is rhombus-shaped and forms parallel to the section 15 extending latch slot portion 17 from. The adjusting piece 22 is received in a receptacle 23 of the lower part 20. The receptacle 23 is inclined with respect to the folding longitudinal direction 12b such that the narrow side 25 always runs parallel to the guide strip 19. The adjusting piece 22 is adjustable within the receptacle 23 and relative to the guide rail 19. This can be the measure 24 change, which measures the parallel offset of the guide rail 19 and the narrow side 25.

The fixation of the adjusting piece 22 takes place in the cover plate 18, as in the FIGS. 2 and 3 shown. The adjusting piece 22 engages with a pin 26 rotatably mounted therein a recess 27, which consists of a plurality of intersecting holes. The overlapping holes lead to constrictions 28 of the recess 27. The pin 26 carries a head 29, the parallel flats 30 has. The remaining cylindrical shell 31 and the flattening 30 are dimensionally matched to the recess 27 such that the cylindrical shell 31 is dimensioned larger in diameter than the clear distance between two opposite constrictions 28. At the same time the distance between the flats 30 is smaller than the clear distance two opposite constrictions 28, so that with a corresponding rotation, corresponding to the enlarged section in Fig. 3 , the pin 26 can be moved and secured within the recess 27.

In order to ensure the locking pin in the region of the locking slot portion 17 a secure locking engagement, the closing slot 11 is arranged in this area in a relative to the lower part 20 and the cover plate 18 movable carriage 32. The carriage 32 is displaceable perpendicular to the folding longitudinal direction 12b by means of two elongated holes 33 and this through-reaching guide pin 34. In the gap ventilation position III, the latch pin which is effective as a holding pin lies in the latch slot section 17 which is movable relative to the closing slot 11 or section 15.

The arrangement thus results in the following mode of action. Starting from the locking position I, the locking pin is displaced along the guide rail 19 when the drive rod fitting is actuated. Upon reaching the opening 14 of the wing 2 can be opened in rotation and pivoted about the vertical axis 5. The espagnolette fitting is in the rotational opening position II. Another shift starting from the Rotary opening position II in the direction of the night ventilation position III causes the locking pin abuts the inwardly projecting protruding ramp 35 of the adjusting piece 22. Upon further displacement of the same direction, the locking pin is pushed out of the plane of the section 15 and abuts the projecting retaining shoulder 36 of the carriage 32, which is thereby displaced in the direction of the arrow 12. The wing 2 is thereby pivoted from a surface-parallel position by an angle. As already indicated above, this can be a pivoting movement about a lower horizontal axis 9. For this purpose, a tilt lock is required on the lower horizontal frame member 7, which defines the wing 2 on the frame 1 pivotally. The opening device located on the wing spar 8 is now in ansich known manner in a Kippöffnungsschaltstellung in which the upper wing edge 37 can be released from the frame 1. A locking plate 10 mounted in the folding area 38, to which a locking pin of the opening device or a corner deflection in the corner area 39 is assigned to the vertical folding area 40, will force the upper wing edge 37 from the frame 1 in the gap ventilation position.

However, it can also be provided in an alternative use that the pivoting movement takes place about the pivot axis 5. Here, the scissors bearing 3 and the corner band 4 are designed as hinges. A display is not required. A striking plate 10 arranged in the region of the fold region 40 here forces the wing edge 41 from the frame 1 and the wing 2 pivoted about the pivot axis 5.

Common to both versions is that further locking pin of the espagnolette fitting cooperate with striking plates 10. For this purpose, the striker plates 10 are to be arranged accordingly. The striking plates 10, which are mounted on a frame spar, which is opposite to the axis (pivot axis 5 or axis 9), receive a maximum dimension 24 of the adjusting piece 22. Striker plates 10, which are attached to frame legs, which are connected to the respective pivot axis 5 or axis. 9 are set at a smaller value 24.

In this way, all existing locking pin locking plates 10 can be assigned. It has been found in practice that when retrofitting a equipped with a display window, the existing on the lower frame member 42 tilt locks can be left. A wing converted as described above receives a secure ventilation position through the arrangement, which can only be overcome by a burglar with difficulty.

To increase the resistance of the striker plate 10 is shown in the Fig. 2 to 4 provided that the arranged in the carriage 32 movable latch slot portion 17 a Overhanging attachment section 43. The attachment portion 43 is formed flat with respect to the rest of the lower part 20 and has through holes 44 for mounting screws. The fastening screws prevent pivoting of the striking plate in a break-in attempt in which by means of high force on the wing is trying to pry the locking pin from the rear handle with the retaining shoulders 13, 36. From the Fig. 4 It can be seen that the strike plate 10 has at the longitudinal ends of a, the cover plate 18 and the movable carriage 32 in the longitudinal direction encompassing collar 45, which also causes better guidance of the carriage 32 in addition to a pleasing appearance.

The Fig. 5 shows a further embodiment. In this case, the lower part 20 is substantially identical to the in Fig. 4 shown lower part, and also the cover plate 18 and the adjusting element 22 remain functionally identical. However, the locking slot portion 17 is provided here in a lever 46 which is pivotally mounted on the cover plate 18 and the lower part 20. The pivotable arrangement is achieved in that the lever 46 is connected to the cover plate 18 via a head rivet 47 forming the axis of rotation and a head rivet 49 which extends through it radially. The gate 48 is mounted in the embodiment 46 in the lever. But it can also be provided that the lever 46 engages with a integrally formed thereon T-shaped guide lug in a corresponding backdrop on the cover plate 18. The lever 46 is shaped and the head rivet 47 is arranged so that the pivotal mounting of the lever 46 is not affected. The operation corresponds to that already described above. Upon displacement starting from the rotary opening position II in the direction of the night ventilation position III, the locking pin abuts the inwardly offset projecting ramp 35 of the adjusting piece 22. Upon further same directional displacement of the locking pin from the plane of the section 15 is caught and thereby abuts the projecting retaining shoulder 36 of the lever 46 thereby moving in the direction of Fig. 5 is pivoted counterclockwise. The locking pin is tightly displaced from the plane of the section 15 moves inward.

This in Fig. 6 shown lower part 20 for the embodiment according to Fig. 5 shows the displaceable position of the adjusting piece 22 in the receptacle 23. At the same time it can be seen that the mounting portion 43 is also formed shallower and next to the through holes 44 a bore 50 for the effective as a guide rivet head rivet 49 and a bore 51 for the axis of rotation acting head rivet 47 has. Further, a flat recess 52 is provided on the attachment portion 43, which surrounds the bore 51. In the flat trough 52, a leg spring, not shown, is received, which is supported with a leg on the lower part 20 and engages with the second leg on the lever 46, which thereby in the in Fig. 5 shown starting position is urged. As a result, an automatic reset of the lever in the rotary opening position II and the Closing position I reached. The pivotable lever adapts to the locking pin 35 along sliding latch pin thereby, if necessary, and is in the rotational opening position II not disturbing the fold before.
