Description

The invention relates to a strike plate for windows or doors according to the preamble of claim 1.

Locking plates of this type are already known. From the AT 372 481 a closure for a window or a door is known, with a arranged on the casement lock body and a frame attached to the lock housing. The lock housing has an outgoing from an insertion opening and away from the frame inclined starting surface with a subsequent gap ventilation position for the sash defining the frame parallel guide surface and the guide surface on the wing side upstream catch web for the locking body. To enable a room ventilation even with closed sash of a window or a door, the sash should be placed only slightly from the frame and held in this night ventilation position. For this purpose, the catch land is displaceably mounted perpendicular to the frame plane and acted upon by a spring which presses the catch land away from the guide surface into a stop-limited, the wing-side contour surface of the lock housing superior working position. With protrusions of the catching bar on the wing-side contour surface of the lock housing, the wing in the night ventilation position can be further adjusted by the measure of the frame.

From the EP 1582673 B1 a strike plate for windows or balcony doors with a slotted guide is known, in which a espagnolette of a casement associated locking bolt is engageable, wherein the strike plate is a window frame assignable, and wherein the slotted guide has a first end portion and a second end portion, with an entry region for the entry of Locking bolt in the slotted guide and with a holding web located between the inlet region, wherein the first end region is arranged offset relative to the second end region transversely to the longitudinal axis direction of the slotted guide. In this case, the retaining web between the first functional position and a second functional position is movable.

To turn off the sash of the frame by a measure in a night ventilation position, it is from the EP 1580375 B1 It is known that a locking bolt arranged on the espagnolette fitting of a casement engages in a striking plate and engages with a retaining web via a link guide from a first end region with a first retaining web in a second end region transverse to the longitudinal axis direction of the window frame. The first end region is arranged offset relative to the second end region transversely to the longitudinal axis direction of the window frame.

A disadvantage of all the above-mentioned embodiments is that a further switching position of the espagnolette fitting is required for the night ventilation position, or a switching position, for example, a closure turn-tilt fitting is converted into a closure-Dreh- Spaltlüftungsstellungs- fitting, thus eliminating an important switching position , Furthermore, changes in the standard switching process are complicated to apply to the user. Furthermore, the known designs do not lend themselves to a rotary wing, i. with a drive rod fitting, which requires half the stroke compared to the lock-tilt and turn fitting to perform with a night ventilation.

The invention has for its object to avoid these disadvantages and to develop a strike plate of the type mentioned in such a way that this can be used for all mentioned embodiments of a standard espagnolette fitting and also in window profiles with a low Nutmittenlage feasible.

To achieve this object, according to the features of claim 1, a strike plate is provided on a window frame of a window or door, with a latching pocket into which a locking bolt connected to a drive rod fitting of a sash frame is engageable. Further, the strike plate on a kraftbeaufschlagtes sliding latch part, which is formed by a parallel to the Blendrahmenfalzkante upstream catching. In this case, the first latching pocket of the striker plate can be assigned to the frame, wherein the latching web points away from the first latching pocket and occupies an abutment-limited position which exceeds the window frame folding edge. As a result, a second latch pocket is formed into which the latch bolt is engageable, wherein the second latch pocket is arranged offset parallel to the first latch pocket. The second latch pocket is transverse in the longitudinal axis direction and perpendicular to the frame arranged in the direction of the sash to the first latch pocket and has, together with the first latch pocket on an engagement plane, wherein the closure position or the night vent position optionally, in the same position of the latch bolt on the espagnolette, starting from a rotationally open position when transferring the window or the door in the closed Window state can be controlled. The conception is to make without further changes suitable to equip both a turn window or a door or a turn-tilt window or door. Characterized in that the latch pockets are arranged offset parallel to each other and perpendicular to the frame form an engagement plane, optionally starting from the open casement when transferring to the closed window state, the closed position or the night ventilation position can be controlled because the second latch pocket during opening of the casement by Federkraftbeaufschlagung automatically is transferred into a free field of activity. The position of the actuating lever and the espagnolette fitting corresponds in a gap ventilation position of the closed position. The user can thus maintain his usual switching position.

It is further provided according to claim 2, that the distance of the contact surface of the Schliessblechs of the Blendrahmenfalzkante corresponds to at least the thickness of the catching web. The design of the Schliessblechs thus has the advantage that the strike plate does not exceed the Blendrahmenfalzkante. The possibility of collision of the Schliessblechs wing flap of the sash in the closed window state is thus prevented because the space required by the Schliessblechs is reduced in the direction of the sash and the same comes a standard Schliessblechs. An additional processing of the window or the door is thus excluded.

In a further development of the invention is provided according to claim 3, that the catching web is L-shaped, wherein a leg engages in a guide of the Schliessblechs. Particularly simple construction conditions arise when the catch land is formed from a leg of an L-shaped elbow whose other leg engages in a guide of the Schliessblechs. The guide can be formed by two elongated holes, in each of which one leg of the elbow is displaceable, which has the advantage that a possible tilting when moving the catchment is to be excluded.

In a further embodiment of the invention is provided according to claim 4, that the slidably mounted in the guide catch is force-urged by a spring, which presses the catch of the Blendrahmenfalzkante away in a Blendrahmenfalzkante superior night ventilation position. A correspondingly wide gap between the casement and the frame is the result, so that desired ventilation conditions are created. The closing of the sash of the window or the door is not hindered despite the projecting catch, because the sash against the force of the spring pushes the catch on the strike plate.

In a further development of the invention, it is provided according to claim 5, that the leg of the catching web has a stop at its free end facing the strike plate, which holds the catching web in a limited position. In order to achieve a clearance-free gap ventilation position so that, for example, a possible rattling is avoided by a wind pressure, the resulting between the spring-loaded catch and the stop surface distance is adapted to the diameter of the locking bolt. With the stop can be relatively easy to manufacture and thus cost, a dimensional adjustment of the size of the distance i. the second latch pocket can be adjusted.

In order to ensure a proper entry of the latch member in the slot ventilation position provided for the latch pocket, the free end of the catch land in a further advantageous embodiment according to claim 6 on its side facing the latch pocket and on the contact surface on an inlet slope. Thus, the locking bolt, starting from the opened sash, finds the opening of the locking pocket even when the locking bolt is not positioned exactly congruent with the second locking pocket.

In the Fig. 1 and Fig. 4 a strike plate 1 is shown in a plan view of a window or a door. The strike plate 1 is connectable to a frame 5 of the window or the door and ensures with the espagnolette, not shown, or with the illustrated locking pin 4 of the sash 3 for a closeability of the window or door. In this case, the striking plate 1 has a arranged on the fold of the frame 5 latch pocket 2, into which engages the connected to the espagnolette of the sash 3 locking bolt 4 in a closed position. Furthermore, the striking plate 1 has a force-loaded latch part 6, which is formed by a catch web 8 which is arranged parallel to the window frame folding edge 7.

The catch land 8 is movable between a first functional position of the closure position and a second functional position of the rotational opening position of the casement 3 to the frame 5, whereby the width of the striker plate 1 is changeable on the side facing the casement 3 side. The side to the frame 5, however, remains constant.

In the Fig. 2 the closing plate 1 is in the second functional position of the rotary opening position of the sash frame 3. With opening of the sash 3, the force-loaded catching web 8 moves automatically in the direction of the sash frame third from the lock plate 1 associated first latching pocket 2 away in a stop-limited, the Blendrahmenfalzkante 7 superior position and forms a second latching pocket 9, in which the freely drawn locking pin 4 is engaged. The second latch pocket 9 is arranged offset parallel to the first latch pocket 2 and forms transversely in the longitudinal axis direction of the frame 5 in the direction of the casement 3 with the first latch pocket 2 an engagement plane. If the window or the door, for example, transferred from a rotationally open position in the direction of an adjacent position of the sash 3 to the frame 5, the user with actuation of an actuating handle arranged on the espagnolette locking bolt 4 optionally at the same position of the locking pin 4 on the espagnolette in the Closing position or be brought into the night ventilation position. The position of the actuating handle is the same in both switching positions. If the window or the door now occupy a parked position, the sash frame 3 is brought before concern of the frame 5 by actuation of the espagnolette by transferring the locking pin 4 of the rotary opening position in the gap ventilation position by the espagnolette fitting is switched to its closed position. The casement 3 is thus held on the frame 5 with engagement of the latch bolt 4 in the second latch pocket 9 of the striker plate 1 in a parked position.

In order to enable a proper displacement with cost-effective production of the catching web 8, the catching web is L-shaped. In the embodiment shown by Fig. 2 and Fig. 3 a leg 12 is divided and receives in a guide 13 of the striker plate 1 a controlled inlet.

In the guide 13 at the same time springs 14 are mounted, which act on the leg 12 by the one-piece design with the catch land 8 transmitting spring force. The catch 8 is after Fig. 2 and Fig. 5 pressed by the guide 13 depending on the direction kraftbeaufschlagt in the gap ventilation position or transferred when locking the sash 3 by pressure of the sash 3 itself on the catch land 8 against the force of the springs 14 in the closed position, so that the catching web 8 after Fig. 4 within the frame 5 and thus at least flush with the Blendrahmenfalzkante 7 comes to rest. For this purpose, the striking plate 1 after Fig. 1 to Fig. 5 a contact surface 11 for the catching web 8, the distance 10 corresponds to Blendrahmenfalzkante 7 at least the thickness of the catching web 8.

To avoid a larger clearance between the locking pin 4 and the resulting with the displacement of the locking bar 8 locking pocket 9, the locking pocket 9 is the diameter or the outer dimensions of the locking pin 4 in the region of engagement of the locking pocket 9 adapted by the leg 12 of the locking bar. 8 at his facing the strike plate 1 free end 15 after Fig. 3 a stop 16 has, which holds the catching bar 8 in cooperation with the locking plate 1 having retaining webs 19 in a limited position.

The inlet of the locking pin 4 is facilitated in the latching pocket 9 for the night ventilation position by a free end 17 of the catching web 8 on the side facing the latch pocket 9 and on the contact surface 11 having inlet slope 18. With a further fold 20 on the outside of the free end 17th of the catch land 8, instead of a plane-like plane, an acute angle is formed, so that a malfunction of the locking bolt 4 and, as a result, possible damage to the strike plate 1 is precluded.

In order for the strike plate 1 to be suitable for a left and a right stop for the sake of simplicity, it is symmetrical, as shown in FIG Fig. 1 to Fig. 5 is shown.

Finally, it should be noted that the illustrated embodiment shows an effective functional element. However, other functional elements of strike plates are also conceivable which cooperate in other embodiments with the same features of the invention with the locking pin 4 or similar locking parts of the sash 3 or the frame 5.
