Abstract

At least one deformable or snap-off lug (45') is positioned between the driving rod (20) and its guide shoe (40), and a cross-direction ledge (19) extends at right angles to the rod length direction. When at least one end of the rod and/or cover rail (30) is extended during mounting of the fitting in the sash or frame, the lug and ledge form end fixtures providing a defined starting position for the rod with respect to the rail and enabling the rod and rail to be extended together. Movement of the rod will eventually result in the ledge deforming or breaking off the lug so that the rod is freely movable in its length direction relative to the rail. The lock fitting mounted on the sash or frame comprises a driving rod provided with a work member such as a sliding bolt and/or operating pin, which is moved in its length direction by an actuator handle. A cover rail secures the fitting to the sash or frame. A guide shoe for the rod includes a core section (41) extending through a slot (25) in the rod.

Description

The invention relates to a fitting in the preamble of Specified claim 1 type. The fitting comprises a structural unit two rod-like elements, namely one fixed on the wing or Frame to be attached cover rail and from a below the cover rail mounted push rod. The push rod is activated by pressing one Handle moved lengthways. The push rod has working links, e.g. one Control pin, which is fixed in the longitudinal movement of the push rod with Interacts with the frame or sash, e.g. one Striker.

The cover rail is not only used to attach the assembly but also to guide the push rod. A contributes to this leadership effect the guide rail arranged guide shoe, which with a The center piece engages in an elongated hole in the push rod.

When installing the unit in the window or frame, the push rod must be as the cover rail is also cut to size according to the available dimensions to match the other structural unit to be arranged next to it. You want to both elements of the assembly together from a cutting tool on the cut off the required length, it must be at a certain position between the Push rod and the cover rail are respected. That position is of it depending on which working push the handle has on the push rod and on which position the working links of the push rod in the different Must be in working positions. With a push rod, where as a working link Sliding bolt is arranged, there may be a need with a handle same type the extension movement of the slide bolt on the wing compared to one Form the bolt holder differently in the frame.

In order to take these different needs into account, the common cutting the assembly into a defined push rod Starting position can be brought opposite the cover rail, which is manual was cumbersome and time consuming. There are fixation devices (DE 42 28 132 A1) between the push rod and cover rail of a structural unit, but had to these differ accordingly for the different applications be positioned. You therefore had to do the same for the different cases provide different units, what the manufacture, storage and Processing makes laborious and expensive. The invention aims to overcome the disadvantages of avoid known fittings.

In a known fitting according to DE 32 40 452 A1, a foot plate can be rotated mounted on a guide slide, which has a locking lug. This takes effect before attaching the fitting to the sash in a recess in the push rod and thereby defines an initial position of the two parts to each other. At the Tightening this assembly, the fastening screw turns the locking plate relative to the guide plate, causing the nose to become a notch in the foot penetrates and releases the push rod. Alternatively, it is provided in one Breakthrough of the guide shoe to a hollow hub due to tear-off webs fasten which with mounting lugs in before mounting the unit on the wing engages diametrically opposite cutouts of the push rod and this with respect to the cover rail. Here too, screwing in Fixing screw in the hollow hub causes this hub to rotate, thereby the locking lugs come out of the cutouts and the push rod to Release longitudinal movement.

With a fitting it is known to have a recess in the core area of a Guide shoe to make (DE 83 23 365 U1). After the final assembly of the Assembly on the wing, a plug is inserted into this recess, which with diametrical longitudinal ribs in mutually opposite recesses in the Push rod engages and fixes them to each other in a certain position. These longitudinal ribs are then sheared off when the push rod is actuated allow longitudinal displacement.

In these known devices there is only a single defined longitudinal position secured between the push rod and the rail, even if the Guide shoe has two lugs on opposite long sides, which in engage two recesses in the drive rod. Both the dimensions of the both recesses and the location of the two lugs are identical and allow only one possible determination position.

The invention has for its object an inexpensive fitting in Preamble of claim 1 to develop the type mentioned Push rod when cutting to length in a reliable, simple manner, accordingly the respective needs, brought into different starting positions can be. This is according to the invention by the in the characteristic of Claim 1 achieved measures, the following special Importance.

In the invention, the guide shoe obtains the cohesion between the cover rail and the push rod in the assembly and The guidance of the push rod in its elongated hole also creates a new one Function, namely to be a carrier for shearable end stops. This End stops are between the core of the guide shoe on the one hand and the slot of the push rod on the other hand arranged and consist of a detachable nose and one transverse to the longitudinal movement of the push rod trending shoulder. These two elements are brief below "Tear tab" and "cross shoulder" are called. As long as the tear tab is not eliminated, it creates with the cross shoulder assigned to it first pair of end stops, which have a first defined starting position the push rod in relation to the cover rail. By this determination can then both elements of the unit together to the desired Can be cut without being in the correct position between the The push rod and cover rail in the structural unit must be observed.

But if another starting position between the push rod and Cover rail is desired, then it is sufficient to use a certain limit force to move the push rod in the assembly to let the tear-off nose shear off the transverse shoulder. Then she can Push rod to be moved longitudinally past the cross shoulder and into one other, second starting position. Then again common cutting of the push rod and the cover rail in the assembly take place in the second starting position. For such a second or too several other starting positions of the push rod with respect to Cover rail can each another pair of tear tabs and Cross shoulders serve.

In this way it is possible, starting from a single unit Type, by making the right pair of Tear tabs and cross shoulders quickly and reliably different Reach the initial positions of the push rod in relation to the cover rail in order to the working links provided on the push rod into a desired one Bring starting position. The end stops created in this way keep you there defined positions that allow the push rod to be cut to length quickly allow the cover rail. Instead of tear-off tabs, protrusions could also be used be used by appropriate counter-projections when applied a certain limit force was not torn down, but still so far deformed so that they are then freely moved past each other can. It is advantageous to have such tabs or projections on the core of the guide shoe to be provided while the cross shoulders are inside the elongated holes of the push rod. The arrangement of these elements could also be a mirror image, i.e. between the core of the Guide shoe and the elongated hole of the push rod.

Only one of the fittings to be installed in a wing 11 is preassembled Assembly 10 shown, the two connected together Rod elements 20, 30, namely a push rod 20 and one Cover rail 30. The structural unit 10 shown should be in the corner region of the wing 11 be arranged and of course with connectable, not shown other units work together. According to the available Dimensions in the wing must therefore be arranged in the corner area Assembly 10, as illustrated by arrows 12 in FIGS. 1 and 2 cut a certain length. That is supposed to be through a common Cut through both rod elements 20, 30 happen.

The push rod 20 has two working members 21, 22 in the present case, namely a slide bolt 21 provided at the rod end and one axially fixed on the push rod 20 control pin 22. The push rod 20 is movable in the direction of arrow 23 in use. The Push rod 20 is structurally connected to the cover rail 30, wherein the cover rail 30, as can be seen from the installation in FIGS. 7 and 8, by fasteners 33, such as screws, for attaching the assembly 10 on wing 11 is used. So that the longitudinal movement 23 of the push rod 20th is executable, the cover rail 30 has an outlet opening 31 for the Slide bolt 21 and an elongated hole 32 for the longitudinal movement 23 of the Control pin 22. The control pin 22 is namely via one of FIGS. 1 and 2 visible rivet bolt 24 firmly connected to the push rod 20. The Elongated hole 32 of the cover rail 30 is penetrated by the rivet bolt 24 while the control pin 22 sitting thereon on the face side of the cover rail 30 comes to lie.

The cover rail 30 also serves to guide the longitudinally movable push rod 20. For this purpose, two guide means are provided, one of which comes from the already mentioned rivet bolts 24 and the elongated hole 32. The other Guide means is formed by a special guide shoe 40, 3 via a rivet bolt 44 visible from FIGS. 3, 4 and 5 on the Cover rail 30 sits. The guide shoe 40 has a core piece 41, the one essentially rectangular shaped profile with two each other has opposite longitudinal surfaces 42, 42 '. On the molded The guide shoe 40 has rivet bolts 44 on the opposite rear side a flange plate 43 which, as best seen in Fig. 5, the Push rod 20 overlaps. To carry out the core 41 has the Push rod 20 in turn an elongated hole 25 shown in FIG. 2 in a is designed to be described in more detail.

For the fastening means 33, the cover rail 30 initially has one Breakthrough 36, a conical depression for the May have screw head. So that the longitudinal movement 23 of the push rod 20 not prevented by the screw 33 passing through the opening 36 is, the push rod 20 is sufficient in this area with a dimensioned slot 26 provided. This is particularly evident from FIG. 8 detect. But there is another breakthrough 34 in the structural unit of As can best be seen from FIG. 3, not only the cover rail 30 but especially also penetrates the guide shoe 40. The cover rail 30 and the Guide shoe 40 are then together, as also shown in FIG. 8 can be seen, penetrated by the associated screw 33.

A handle, not shown, is provided on the wing, through which Actuation of the longitudinal movement 23 of the push rod, which has already been mentioned several times 20 takes place. The handle actuation causes the push rod 20 moved longitudinally by the stroke distance 16. In Fig. 1, in solid lines, one Starting position of the push rod 20 is drawn, the position of which Bolt tip 27 of the aforementioned slide bolt 21 should be determined what is illustrated by the auxiliary line 14 in FIG. 1. Dash-dotted is in Fig. 1 also the position of the slide bolt in the after the handle operation resulting end position shown, which in Fig. 1 by the Auxiliary line 15 is clarified. 1 is the starting position 14 of the push rod 20 is determined by the fact that the bolt tip 27 by one Route 28 opposite the angled cover rail end 38 is reset.

If one assumes that the resulting by operating the handle Stroke 16 is about 19mm and the aforementioned offset 28 of the Bolt tip 27 is 7mm, this results in locking in a fixed frame provided, not shown bolt holder an effective extension of 12 mm, which in FIG is made clear.

Starting from the same unit 10, as from the rest 9 to 13 can be seen, there is a need with the same door or window fitting the slide bolt 21 in one drive much greater depth into the frame-side transom mount to let. This is effective in Fig. 9 by the much larger Extension line 39 illustrated. In this second extension section 39 arrives, as shown in dash-dotted lines in Fig. 9, the latch tip 27 to to a much further away from the end of the cover rail 38 End position 18. Starting from those mentioned in connection with FIG. 1 In concrete dimensions, this means that this alternative extension route 39 of FIG. 9 is approximately 19 mm, that is to say equal to the available stroke length 16 the handle actuation.

This means that with the alternative application of the fitting 10 in 9 to 13, the latch tip 27 in the retracted position of the Slide bolt 21 essentially flush with the one already mentioned several times Cover rail end must be 38. That is in Fig. 9 and Fig. 10 by the solid position of the push rod 20 illustrates and marked by the auxiliary line 17. Because of the rivet-proof connection of the Control pin 22 with the push rod 20 takes the control pin 22 in the two starting positions of Fig. 1 on the one hand and Fig. 9 on the other hand accordingly, staggered location, which is already described Position of the bolt tip 27 results in the two cases. The offset results from the distance 28 of Fig. 1 and is 7mm for the dimensions mentioned.

In Fig. 9, the concrete stroke 16 of the push rod 20 between the solid drawn second starting position of the control pin 22 and the dashed end position of the control pin through section 16 clarified. There now exists, in analogy to that explained in FIGS. 1 and 2 Situation in the first starting position 14 there both need Rod elements 20, 30 together to the required length cut off when the push rod 20 is opposite the cover rail 30 in the aforementioned second, illustrated by the auxiliary line 17 Starting position is. This is again in Fig. 9 and 10 by a common arrow 13 illustrated for this cut.

As can be seen, the common cutting of the same structural unit 10 is at a given fitting of a uniform type and for a window same dimension in the cut in the area of the push rod 20 depends on whether it is in the desired first starting position 14 1 or in the second starting position 17 according to FIG. 9. With the identical sash dimension of the window, however, the cover rail 30 cut in the same place in both cases. Do you want that Separating cut 12 in FIG. 1 and 13 in FIG. 9 in both rod elements 20, Execute 30 together, the push rod 20 must in each associated starting positions 14 in Fig. 1 and 17 in Fig. 9 brought become. This requires not only a high level of attention from the installer but also also a lot of work for setting the respective location. This differs, according to the position of the bolt tip 27, between the 1 and 9, on the other hand, by the distance 28 shown in FIG. 1 Invention solves this problem in a very elegant and simple way by the guide shoe 40 a new "alignment function" of the push rod 20th opposite the cover rail 30 there.

The special feature of the invention is that the guide shoe 40 with two tear-off tabs 45, 45 'is provided. Because the guide shoe 40 is firm sits on the cover rail 30, the tear-off tabs 45, 45 'define defined Place the cover rail 30. You can now use it to define end stops generate with the push rod 20 when you are in the push rod with it interacting shoulders 19, 19 'running transversely to the longitudinal movement 23 provides that are to be referred to as "transverse shoulders" in the following. The Tear tabs 45, 45 'are aligned transversely to one another and are located opposite each other, on the longitudinal surfaces already mentioned 42, 42 'from the core piece 41. The transverse shoulders 19, 19' are by a best distance from each other 49 shown in Fig. 11 apart. The Cross shoulders 19, 19 'arise due to step-like extensions 29, 29' the two opposite longitudinal edges 46, 46 'of the for guidance from the core piece 41 serving elongated hole 25 in the push rod 20. Die Cross shoulders 19, 19 'are each rear boundaries of this step-shaped Extensions 29, 29 ', which also have a front boundary 35, such as is shown at 29 in FIG.

The assembly of the structural unit 10 comes from the rod elements 20, 30 in that the guide shoe 40 with its two tear-off tabs 45, 45 'in the region of the elongated hole widenings 29 shown in FIG. 4 or 29 'is inserted and then with its bolt 44 on the cover rail 30th is riveted. Because, as shown in FIG. 6, the length 48 of the stepped extension 29 shorter than the length 48 'of opposite extension 29 'is formed, first determines the Dimensions 48 of the extension 29 with respect to the position of the push rod 20 the cover rail 30. The play of the tear-off nose 45 shown in FIG. 6 between the two level transitions 35, 19 in the extension 29 of the Length 48 is necessary to connect adjacent units serving tooth coupling between the push rod 20 with the analog to consider adjacent rod element. The push rod 20 has namely, as can be seen from FIGS. 1 and 2, suitable for this coupling Teeth 50.

A defined one is obtained which is described in connection with FIG. 1 Starting position of the push rod 20 relative to the cover rail 30 according to the auxiliary line 14 there, by, as can be seen from FIG. 6, the Tear tab 45 with its one axial end 51 on the transverse shoulder 19 Plant brings. In this position, the one already mentioned several times can then be used Cutting 12 of Fig. 1 and 2 of the unit. Around The fitter does not have to worry about position because of the tear-off nose 45 caught in the extension 29 this first Starting position 14 already exists from the start.

If the fitter explained this in connection with FIGS. 9 and 10 Cut to length at 13 in the second starting position 17 of the push rod 20 he then only needs the first tear-off tab 45 of FIG. 6 remove. This is done simply by going through a small axial Movement of the push rod 20 separates the nose 45. This is the special one Profile shape of the nose 45 useful, which with its nose flanks 52 what in 4 can be seen at the attachment point designated 47 in FIG. 6 the centerpiece longitudinal surface 42 tapers. The same applies to the Starting point 47 'of the opposite tear-off nose 45'. When a A sufficiently large axial force 53 according to FIG. 6 on the push rod 20 is exercised, the transverse shoulder 19 exercises on the trapezoidal profile Tear tab 45 on the nose end 51 a bending stress from the a crack at the weakened attachment point 47. Then it is Removed the impact at this point.

This second starting position is also determined by analog stops, as illustrated in FIG. 11. Now the cross shoulder 19 'of opposite step-shaped expansion 29 'effective. This happens, if the push rod 20 by the aforementioned distance 49 between the two transverse shoulders 19, 19 'is moved on. This distance 49 is however equal to the route 28 already explained in connection with FIG. 1, which, in comparison with FIG. 9, just the position difference of the latch tip 27 in the two starting positions 14 and 17 of the push rod 20 in FIG. 1 and Fig. 9 corresponds. So if the second tear-off tab 45 'in its from Fig. 11 apparent stop position is brought, where its axial end 51 'at the Cross shoulder 19 'is supported, so there is an exact adjustment of the second starting position according to FIGS. 9 and 10. This second 11 is automatically given without the Fitter needed to take care of this in detail. The fitter can now do that 9 and 10 to make the desired cut 13 Unit to the length corresponding to the wing 11 of FIG. 12 to cut.

After assembly using the screws 33 also shown in FIGS. 12 and 13 the push rod 20 can be moved through the above-mentioned stroke 16 again Move actuation of the handle. In the first phase of this movement by exerting a limit force illustrated in FIG. 11 by arrow 53 ' the tear-off nose 45 'separated over the shoulder 19'. At the final Longitudinal movement 23 of the push rod 20 according to FIG. 13 are therefore both Tear tabs 45, 45 'sheared off. There is a core 41 with protrusion-free Longitudinal surfaces 42, 42 'in front.

As can be seen from the cross sections of FIGS. 6 and 11, there is between the core piece 41 and the longitudinal inner edges 46, 46 'of the elongated hole 25 in the Push rod 20 a side game. To the correct location of the second To ensure tear-off nose 45 'according to FIG. 11, it is therefore recommended that Profile floor 54 in the extension 29 'a management function over the To give nose bridge 55 of tear-off nose 45 '. This bridge of nose 55 is from the trapezoidal base of the trapezoidal nose profile described above. This guiding effect on the profile floor 54 can be increased if the 11 apparent depth 56 of the profile bottom 54 when approaching the there transverse shoulder 19 'reduced. This leads to a touch the opposite longitudinal surface 42 of the core piece 41 with the one there Longitudinal inner edge 46 in the slot 25 of the push rod 20. This is both the impact action as well as the desired severing of the tear-off nose 45 ' secured.

The guide shoe 40 is produced as an injection molded part and consists e.g. out Zinc pressure casting. For shaping the lugs 45, 45 'on the core piece 41 43 openings 57, 57 'are formed in the flange plate covering them. intended. These openings 57, 57 'are used for carrying out components the injection mold.

   whilst all the snap off lugs (45, 45') located at a short longitudinal distance from their transverse shoulders (19, 19') relative to the current end stop pair are deformed and sheared off by a previously limited displacement (53, 53') of the push rod (20), the distance of this displacement (49) being smaller than/the same as the longitudinal distance between the current end stop pair (45'; 19').
2. Component according to claim 1, characterised in that the working members (21, 22) of the fitting are always controllable along the same lifting path (16) by the handle but adopt an initial position (14; 17) in the fitting (10) selectively different in length from one another,
   in order to reach, after actuating (16) the fitting, corresponding end positions (15; 18) different in length from one another,
   and the respective desired initial position (14; 17) of the working members (21, 22) is defined by a pair of snap off lugs (45; 45') and transverse
   shoulders (19, 19') acting together and the respective initial position of the push rod (20) relative to the cover rail (30) is fixed by this pair.
3. Component according to claim 2, characterised in that the working members (21, 22) in the component (10) are designed to start selectively from one of two initial positions (14, 17) longitudinally separated from one another, which correspond to two different initial positions of the push rod (20) in the component (10) and the two initial positions (14, 17) are respectively defined by a pair of matching snap off lugs (45, 45') and transverse shoulders (19, 19').
4. Component according to at least one of claims 1 to 3, characterised in that a widening (29) of the longitudinal hole (25) at both respective ends has a stepped junction (19, 35) with the adjacent unwidened longitudinal edge (46, 46') of the longitudinal hole (25) and which allows an adjustment clearance of the push rod (20) in the component (10), the two stepped junctions (19, 35) defining a widening (29) with the snap off lug (45) located therebetween.
5. Component according to at least one of claims 1 to 4, characterised in that with the longitudinal movement (23) of the push rod (20) the snap off lug (45') is guided with its tip surface (55) at least partially on the profiled base (54) of the widening (29'), this guiding taking place in particular in the part of the profiled base (54) preceding the transverse shoulder (19') which has a deforming and shearing off action.
6. Component according to claim 5, characterised in that the profiled base (54) of the widening (29') has an oblique extension relative to the longitudinal direction of the push rod (20), the depth (56) of the profiled base (54) decreasing when it approaches the transverse shoulder (19') which has a deforming and shearing off action.
7. Component according to at least one of claims 1 to 6, characterised in that the snap off lug (45) comprises a nose protruding out beyond the longitudinal inner face (42) acting as a guide, of the core part (41) of the guide shoe (40).
8. Component according to claim 7, characterised in that the contour of the nose tapers to a position of the nose (47) on the core part (41) and this tapering produces undercut lug sides (52).
9. Component according to claim 8, characterised in that the guide shoe (40) has a flange plate (43) overlapping the push rod (20) and the snap off lug (45) is arranged near the flange plate (43) on the core part (41) and the flange plate (43) in the profile region of the snap off lug (45, 45') has an opening (57, 57') which exposes the snap off lug (45, 45') toward the outer face of the flange plate (43).
