DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0067] FIG. 1 shows the mullion of a window in a closed condition, in particular a profile 1 of the fixed frame of the window and a profile 2 of the hingeable wing. Profiles 1 and 2 are aluminium profiles for example.

[0068] On the sides facing each other 3 the profiles 1 and 2 are provided with a fitting groove 4 which extends lengthways along x and which is defined by two upstanding ribs 5 with jaws oriented toward each other in a perpendicular way which form the flanks 6 of the fitting groove 4 and which limit the width W of this fitting groove 4.

[0069] In the fitting groove 4 of the profile 1 of the fixed frame a striker 7 according to the invention is mounted by means of a screw 8 which is screwed in the bottom 9 of the groove 4.

[0070] In the fitting groove 4 of the profile 2 of the wing a close slat 10 is provided which has been mounted slidably in the fitting groove 4 and in a known way can be slid in the fitting groove 4 by means of a handle or another control to open or shut the window.

[0071] The close slat 10 bears a locking cam 11 which in this case is hook-shaped and which by means of said handle can be hooked behind the striker 7 as shown in FIG. 1 or can be withdrawn to open the window.

[0072] An alternative locking system is known whereby the close slat 10 is blocked in the fitting groove in a setting whereby the locking cam 11 holds a fixed position between the hinges of the window opposite the striker 7, such that the locking cam 11 hooks behind the striker 7 by the turning movement of the wing when closing the window or door.

[0073] Both locking methods are possible, either with the handle or the turning movement of the wing.

[0074] In each of both these methods the locking cam 11 must press firmly against the striker 7 in the lateral direction y perpendicular to the longitudinal direction x of the fitting groove 4 to ensure proper closing.

[0075] For this it is necessary that the position of the contact zone 12 between the locking cam 11 and the striker 7 is adjustable to compensate for the manufacturing and mounting tolerances which ensure that the mutual positions of the opposite fitting grooves 4 of the fixed frame and of the wing can change in the lateral direction y and in the depth direction z by changing their mutual distance.

[0076] To this end, the striker according to the invention is adjustable in a way described below.

[0077] The striker 7 as shown in the FIGS. 3 to 5 is composed of a foot 13 and a head 14 mounted directly along one side thereon.

[0078] The foot 13 is formed as a disk with edges 15 that define a circumference in the form of a regular polygon with an even number of sides and characterised by an inscribed circle 16, indicated in FIG. 5 with a dashed line, with a centre point 17 and a diameter K, which is equal to or slightly smaller than the width W of the fitting groove 4.

[0079] The diameter K of the inscribed circle is also equal to the distance between two facing edges 15 of the foot, whereby the distance in this location determines the width of the foot 13.

[0080] In the example shown in FIGS. 1 to 5 the regular polygon is a square with width K.

[0081] Such foot thus fits between the flanks 6 of the fitting groove 4 and this in as many different positions as there are edges 15.

[0082] In the shown example with a square foot 13 the striker 7 with its foot 13 can be mounted fittingly in four different positions between the flanks 6 of the fitting groove 4 as shown in FIGS. 6 to 9.

[0083] The different positions differ from each other by a rotation of the striker 7 around a geometric axis Z-Z through a centre point of the foot 13 that coincides with the centre point 17 of the inscribed circle 16 and which in mounted condition is located in the middle of the fitting groove 4. The centre point 17 can also be determined as the intersection of the geometric centre lines of the groove which can be marked in every position on the foot 13. In FIG. 5 these centre lines are indicated by lines U-U and V-V, whereby the centre lines of each pair of positions coincide with a rotation over a half turn.

[0084] In each of these mounted positions the striker 7 is blocked between the flanks 6 of the fitting groove 4 so it cannot rotate.

[0085] The geometric axis Z-Z in the example coincides with the axis of the screw 8 which, however, does not necessarily have to be the case.

[0086] In the extreme, the foot can also be executed as a disk with a circular circumference that coincides with the inscribed circle 16. This means the regular polygon has an infinite number of sides and there are an infinite number of intermediate positions.

[0087] The head 14 of the striker 7 has a circumference with straight edges 20 that are determined by the sides of a regular polygon with an inscribed circle 18 with a diameter that is greater than the width W of the fitting groove and the centre point 19 of which is excentrically located in relation to the geometric axis Z-Z through the centre point 17 of the foot 13, such that the radial normal distance of the edges 20 to the geometric axis Z-Z is different for each edge 20. Straight edges 20 here are understood to mean edges that are rectilinear between two corner points.

[0088] In the shown example, centre point 19 in relation to the centre point 17 has shifted according to two orthogonal directions X and Y and over a different distance in every direction.

[0089] Preferably, the number of straight edges of the head 14 is equal to the number of straight edges of the foot 13 and the edges 15 and 20 are parallel to each other, such that for every straight edge 15 there is a corresponding edge 20 the orthogonal distance of which to the geometric axis Z-Z is different as shown in FIG. 5 in which these distances are indicated with the letters A to D respectively and whereby in this case the distance D is the greatest, followed by the distances A and C to end with the smallest distance B.

[0090] Thanks to this difference in distances A to D you also obtain a difference in the distances A to D between the straight edges 20 of the head 14 and the corresponding straight edges 15 of the foot 13.

[0091] The distances A to D determine the position of the edge 20 that is located closest to the locking cam 11 and is parallel with the longitudinal direction x of the fitting groove 4 in relation to the centre of this fitting groove 4.

[0092] That means that these distances also determine the lateral position of this edge 20 in relation to the locking cam 11.

[0093] In this way a lateral adjustment of the locking system 7-11 is possible by a simple rotation of the mounting position of the striker 7.

[0094] FIGS. 10 to 13 show an alternative embodiment of a striker 7 according to the invention, the difference being that in this case the foot 13, on the opposite side of the head 14, is provided with a clamping piece 21 which along every edge 15 of the foot 13 extends laterally with a collar 22 in relation to the edges 15 of the foot 13.

[0095] In this case the head 14 is connected with the foot 13 by means of a connecting piece 23 with a thickness L which is equal to or greater than the thickness M of the flanks 6 of the fitting groove 4 and which at least along two non-facing edges 15 of the foot 13 indents laterally inwardly in relation to these edges 15.

[0096] Preferably, this embodiment of a striker 7 is dimensioned such that the striker 7 with the collar 22 of the clamping piece 21 can be hooked behind a flank 6 of the fitting groove 4 and can be tilted into one of said positions in a way as shown in FIG. 16.

[0097] It can be useful here that, depending on the depth of the fitting groove 4, the bottom 24 of the clamping piece 21 is bevelled narrowingly toward the edges 25 of the clamping piece 21, whereby the edges 25, or a part thereof, can also be bevelled inwardly.

[0098] In this embodiment with clamping piece 21 the striker 7 is provided with a screw thread channel 26 with internal thread and a fitting screw 27 which, when it is screwed in the screw thread channel 26, can push against the bottom 9 of the fitting groove 4 to clamp the striker 7 with the collar 22 of the clamping piece 21 tight against the flanks 6 of the fitting groove 4 as shown in the FIGS. 17 to 20 which shows the different settings of the striker 7, and this in the same way as shown in the FIGS. 6 to 9 of the first embodiment.

[0099] FIGS. 21 to 23 describe a third embodiment of a striker 7 according to the invention whereby in this case the centre point 19 in the two orthogonal directions x and y is shifted over the same distance, such that every time two adjacent edges 20 of the head 14 are located at a same distance A, respectively B, from the centre point 17 of the foot 13.

[0100] Two facing edges 20 are executed with a same thickness P, whereas the two other facing walls are executed with a different thickness Q as shown in FIGS. 22 and 23, whereby the thickness P and Q are measured according to a direction parallel with the geometric axis Z-Z of the striker 7.

[0101] In this case too, the striker 7 has four settings that are shown in FIGS. 24 to 27, whereby in this case both a lateral adjustment and a depth adjustment can be realised.

[0102] In the settings of the FIGS. 24 and 26 the edge 20 which is in contact with the locking cam 11 has the same thickness in both cases with a thickness P but by rotating the striker 7 a half turn the lateral distance of this edge 20 to the middle of the fitting groove 4 can be adjusted and because of this the lateral position of this edge 20 in relation to the locking cam 11 too.

[0103] By rotating the striker a quarter turn to the position of FIG. 27, departing from the position of FIG. 24, the lateral adjustment distance A is retained, but the locking cam 11 is now in contact with a thicker edge 20 with thickness Q.

[0104] In this way a combined lateral and depth adjustment is possible.

[0105] Alternatively, the head 14 is not shifted excentrically in relation to the foot 13 and the four edges 20 show a different thickness.

[0106] In this case the adjustment is restricted to a depth adjustment.

[0107] It is clear that the foot 13 does not necessarily have to have straight edges, but needs a form that allows the foot to be blocked in different positions in the fitting groove, which positions differ from each other by a mutual rotation of the positions around a geometric axis Z-Z through a centre point 17 that is determined as intersection of the middle lines of the fitting groove 4 which can be projected in the different positions on the foot 13. A possible example of this is shown in FIG. 28 in which the foot 13 is star-shaped with a centre point 17 in the intersection of the centre lines U-U and V-V.

[0108] It is clear that the edges of the head do not necessarily have to be straight, but that, for example, a circular head 14 can be combined with a polygonal foot 13 or a head 14 with an irregular form the edges 20 of which are located locally along the different centre lines of each pair of parallel edges of the foot 13 at a different distance A,B,C,D of the geometric axis Z-Z as in these local places the contact zone 12 with the locking cam 11 is situated. FIG. 28 is an example of this with a star-shaped head that is centred in relation to the centre point 17.

[0109] FIGS. 29 and 30 show another variant of a striker 7 according to the invention.

[0110] It is also clear that the diameter of the inscribed circle 18 can be smaller than the diameter of the inscribed circle 16. In that case the striker 7 can be mounted in the fitting groove 4 by means of an aforementioned clamping piece 21 or by screwing the striker 7 against the bottom 9 of the fitting groove 4.

[0111] A variant embodiment of a striker 7 according to the invention is shown in the FIGS. 29 to 32.

[0112] In this case the foot 13 is executed as a rectangular slat which only fits in the fitting groove in two ways, more specifically in two positions that are rotated half a turn in relation to each other around an axis Z-Z through a centre point 17 located on centre line U-U of the foot 13 corresponding with said two positions.

[0113] The head in the example is executed as a U-shaped profile which when locking the window or the door grips over a locking cam 11 in the form of a pen with this locking cam 11 between the legs 28.

[0114] In this case the contact zones 12 with the locking cam 11 are located on the edges 29 of the legs facing each other 28 of the striker 7.

[0115] The head 14 is connected with the foot such that the lengthways edges 29 are parallel with the centre line U-U of the foot 13, whereby the U-shaped end piece has excentrically shifted in relation to the centre line U-U in a direction perpendicular to the centre line U-U or at least such that the edges 29 and therefore also the contact zones 12 are located at a different distance A, respectively B, from the centre line U-U.

[0116] In this way a simple lateral adjustment is obtained in two settings by mounting the striker 7 in the one or in the other of the two possible positions in the fitting groove 4 as illustrated with the FIGS. 29 and 30 which each show one of the two settings.

[0117] In the variant embodiment of FIG. 31, the thickness of the legs 28 is additionally executed varyingly in the profile directions of the legs such that the distance of the edges 29 of the legs 28 also varies in this direction such that the width of the groove 30 between the legs 28 from each end of the U-shaped head 14 gets smaller toward the middle and this groove 30 thus narrows toward the middle.

[0118] This makes an additional lateral adjustment possible by shifting the striker in the one or in the other position in a longitudinal direction x of the fitting groove 4.

[0119] FIG. 32 shows another optional additional depth adjustment by executing the edges 29 of the legs 28 with a slope such that the width of the groove 30 becomes smaller from the opening of the groove 30 to the bottom of this groove 30 and the thickness of the edges 29 is, in other words, variable in the direction Z-Z.

[0120] This makes a depth adjustment possible by shifting the striker 7 lengthways along x of the fitting groove 4.

[0121] The present invention is by no means limited to the embodiments described as an example and shown in the drawings, but a striker according to the invention for a door or window that can be realised in all kinds of forms and dimensions, without departing from the scope of the invention.
