This strap slides in the fixed frame of the window and has holding arm with hooked end. A spring-loaded (30) holding arm (28) is hinged (26) to the U-section holding member and has a hooked end (22). There is an entry gap (18) between the hooked end of the holding arm and a projection on the holding member and there is a sloping edge (20) on the holding member opposite the entry gap.

Description

The invention relates to a strike plate for windows or balcony doors, with a slide guide, in which a connected to a espagnolette of a casement lock bolt is engageable, wherein the strike plate is assigned to a frame, and wherein the slide guide has a first end portion and a second end portion, with a Entry region for the entry of the locking bolt in the slotted guide, and with a located between the inlet region and the second end region retaining web, wherein the first end region opposite to the second end region is arranged offset transversely to the longitudinal axis direction of the slotted guide.

From the DE 30 43 925 C2 a window is known in which the sash is opposite the frame in parallel shut off. The parallel Abstellbewegung is effected by striking plates whose slide guides have a plane offset. Runs a locking pin of the sash through the slotted guide, it is laterally displaced by the plane offset to its actual movement, causing the casement is pushed away from the frame.

For window profiles with low groove center position, so a small distance between the Rahmenfalzkante and the Grooved position in the closed state, there is the problem that when using strike plates with a plane offset in the slotted guides of the space in the direction of the sash override is not sufficient to accommodate the strike plate.

From the DE 100 05 055 A1 a strike plate is known in which an extendable tightening device is provided a locking pin to facilitate retraction into the strike plate.

The invention has the object of developing a strike plate of the type mentioned in such a way that it can also be used for window profiles with a low Nutmittenlage.

To achieve this object, it is provided according to the features of the preamble of claim 1, that the holding web is mounted so movable that it is movable between a first functional position and a second functional position, whereby the width of the second end portion is variable. The variable width of the second end portion has the consequence that in the closed state of the window, when the locking pin is in the first end region, the second end portion is variable so that its space requirement is reduced in the direction of the wing flashover. As a result, such a strike plate can be used for window profiles with low groove center positions, since the space required in the direction of the wing flap in the closed window position is reduced.

In a further development of the invention is provided according to claim 2, that in the first functional position of the holding web, the width of the slotted guide in the second end region is smaller than the width of the slotted guide in the first end region, and wherein in the second functional position of the holding web, the width of the slotted guide in the second end region is equal to or greater than the width of the slotted guide in the first end region. The second end area is reduced compared to the first end area in the closed window state, with the result that the space required in the direction of the wing flap for this case is also reduced.

In a further embodiment of the invention is provided according to claim 3 that in the first functional position of the retaining web, the width of the slotted guide in the second end region is less than the diameter of the locking bolt, and wherein in the second functional position of the retaining web, the width of the slotted guide in the second end region or larger than the diameter of the locking bolt. Here, too, the possibility of collision is prevented for the closed window state, in which the strike plate and the wing overlap come closest, since the space requirement of the strike plate is reduced in the direction of the wing flashover.

In a further development of the invention is provided according to claim 4 and 5, that the holding web is arranged rotatably about a rotation axis, wherein the rotation axis is located outside of the holding web and the holding web is connected via a support arm with the axis of rotation. The storage relative to a rotation axis has the advantage that with a single bearing point a simple mobility of the holding web is implemented.

In a further embodiment of the invention, it is provided according to claim 6, that the retaining web displaceable perpendicular to the direction of the guide slot longitudinal axes is stored. A displaceability of the retaining web has the advantage of a very accurate and above all parallel leadership of the retaining web against the slide guides.

In a further development of the invention is provided according to claim 7 and 8, that the holding web is biased by a spring element in the direction of the first gate section, wherein the spring element is designed as a compression spring with a spiral shape. The spring element ensures an automatic return of the retaining element in the direction of the striking plate as soon as the locking pin has left the link guide in the second end region.

In a further embodiment of the invention is provided according to claim 9 and 10, that the first end of a closed window position and the second end of a parallel parked window position is assigned, wherein the first functional position of the retaining web of the closed window position and the second functional position of the retaining web of parallel parked window position assigned. This assignment fits into the entire closing sequence and the requirements of the entire espagnolette fitting.

In a further development of the invention is provided according to claim 11 and 12 that the strike plate is mounted on a strike plate base plate, wherein the strike plate is slidably mounted relative to the Schießblech base plate parallel to the direction of the slotted guide longitudinal axes, and wherein the strike plate at least one perpendicular to Direction of the slotted guide longitudinal axes extending adjusting channel, in which an adjusting pin of the espagnolette fitting for adjustment of the strike plate is engageable. This is a simple one Adjustment of the striker against the espagnolette fitting possible, so that tolerances and stroke losses of the espagnolette fitting are compensated.

In a further embodiment of the invention is provided according to claim 13, that the retaining web is biased by a spring element in the opposite direction of the first gate section. By this alternative embodiment, the inlet of the locking bolt is facilitated in the second end region, since the movement of the retaining web is supported by the spring element. In this case, the retaining bar is pressed by the wing flap.

Fig. 1 shows a plan view of a strike plate 10 for a window. The strike plate 10 is connected to a not shown Blend of the window connected and together with the espagnolette, not shown, or locking pin of the sash ensures a closeability of the window. The striker leading edge 11 is located approximately flush with the Rahmenfalzkante of the window frame.

The central functional element of the striking plate 10 is a slotted guide 12, which has a first end region 14 and a second end region 16. The slide guide 12 has a plane offset transversely to the longitudinal axis direction of the slide guide between the first and second end regions 14, 16, recognizable by the offset edge 20. Between the inlet region 18 and the second end portion 16 is a holding web 22 which forms a portion of the walls of the slotted guide 12.

The holding web 22 is movable between a first and a second functional position, whereby the width 24 of the second end portion 16 is variable. The width 25 of the first end portion 14, however, is constant. In Fig. 1 while the first functional position is shown, whereas Fig. 2 the second functional position shows.

The holding web 22 is rotatably mounted about a rotation axis 26, wherein a holding arm 28 connects the holding web with the region of the rotation axis 26. For biasing the retaining web 22 is a spring element 30 which is formed as a spiral spring. The spring element exerts a restoring force on the holding arm 28 and thus on the holding web 22 integrally connected therewith, so that it is pressed in the direction of the striking plate and in the opposite direction of the sash overlap.

If, for example, we closed the window from a rotationally opened position, the locking pin enters the slotted guide via the entry area. For the closed window state, he will then, based on the Figures 1 and 2 , is moved to the left within the slotted guide until it is positioned in the closed position in the first end region 14. If the window is now to be brought into a parallel parked position, then the locking pin is advanced up to the right into the second end region 16 within the slotted guide. Due to the plane offset on the offset edge 20, the window is shut off in parallel.

During the transition from the inlet region 18 into the second end region 16, the locking bolt strikes against the insertion bevel 32 and, with further progression, begins the retaining web 22 in FIG Fig. 1 and 2 to move down. Since at the same time the sash frame stands out from the frame, creates the necessary space to accommodate the retaining bar 22. In a return movement of the locking bolt in the direction of the inlet region 18, the retaining web 22 is retracted by the spring element 30, so that a collision between the retaining web 22 and sash overlap is avoided.

Fig. 3 to 5 show the strike plate 10 in a three-dimensional view in three different positions. In addition to the Fig. 1 and 2 is shown in this strike plate an adjusting device 38. It gives the lock plate for the adjustment by the adjustment channel 34 degree of freedom in the direction of Längserstrekkung the strike plate. The locking pin 40 is drawn free in all representations. In the later installation situation he would be secured with the locking pin shaft 42 in the drive rod of the espagnolette fitting.

Fig. 3 shows the locking pin 40 located in the first end portion 14 of the slotted guide 12. The retaining web 22 is biased by the spring element 30 in the direction of the first link section 31. This position corresponds to the closed window position. Fig. 4 shows, in contrast, how the locking pin 40 has been moved through the slide guide 12 and is about to push away the retaining web 22 against the spring force of the spring element 30 from the first gate section 31. Im in Fig. 5 illustrated state of the locking pin is almost reached in the second end 16. This corresponds to the parallel window position. He has thus moved the retaining bar 22 almost completely against the spring force of the spring element 30. Upon a return movement of the locking pin out of the second end region 16, the retaining web 22 is retracted again by the spring element 30. This creates a solution that the retaining element 22 only when needed, namely when the window is brought into the parked position, extends. In this case, by the Abstellbewegung at the same time the space for the retaining element. In the closed window state, however, if the space is not available, since the sash fits tightly against the frame, the holding element is retracted.

In Fig. 6 an alternative embodiment of the striking plate 11 is shown. The basic function corresponds to that of the above-mentioned embodiment. In contrast, the retaining web 22 by a spring element 50 in Fig. 6 biased downwards. The spring element 50 is supported once on the support 52 connected to the strut fuselage 52 and on a with the support arm 22 connected support arm 54 from. Upon entry of the locking pin in the second end portion 16, the required forces are reduced because no force for movement of the holding member 22 and against the spring force must be expended. The retraction of the retaining element 22 is effected by the wing flap of the sash.

FIGS. 7 and 8 show a further alternative embodiment, which is based essentially on the embodiment Fig. 6 inspired. The sectional view shows a modified embodiment of the leaf spring 60. The leaf spring 60 is clamped on one side in the leaf spring bearing 62 and thus acts in the manner of a cantilevered cantilever beam. The bias of the leaf spring 60 depends, as in the embodiment according to Fig. 6 , also in Fig.7 and 8 downward. Fig. 7 shows the representation in which the locking pin is already retracted in the second end region. Fig. 8 on the other hand shows the locking pin in the first end region, wherein the holding arm 22 is pressed against the spring force of the leaf spring 60 by the wing flap of the sash frame, not shown.
