Description

The subject of the innovation is a coupling device for drive rods of Espagnolette fittings according to the preamble of claim 1.

Coupling devices of this type are already available in many embodiments known. From DE 199 13 306 A1 an espagnolette is to refer, which consists of several rods, which means Positive locking elements in the form of interlocking teeth are detachable. The drive rods have a flat rectangular or round cross-section, these at the bottom of one in the fold of the wing arranged Beschlagaufnahmenut fastened by means of fasteners and are guided longitudinally displaceable.

The drive rod is supported by a bottom side of a tooth box arranged as a spacer effective projection at the bottom of Damping up the frame, so that the serrations of the caste and the the second drive rod to be coupled in parallel with the coupling to each other and thus the tooth box something from the bottom of the Beschlagaufnahmenut remains spaced around an unwanted grinding and to avoid the associated friction. The disadvantage is that the projection in particular when mounting on wings soft framework materials such as wood can press into the bottom of the groove and thus leads to particular stiffness when in operation of the Espagnolette fitting the projection dips into the resulting trough and hooked.

From DE-U 7108480 a drive rod fitting is known, which also Fastening devices in the Beschlagaufnahmenut provides that also for Guiding the drive rod serve. This is also a buckling of the flat rectangular drive rod can be prevented. The fastening device provides essentially U-shaped locking members, which by means of a Fixing screw before mounting the drive rods in the bottom of the fitting groove be attached. The parallel to the groove side walls - perpendicular to the bottom of Beschlagaufnahmenut- protruding leg The Rastlieder are resilient and can be used to clip the drive rod be deformed elastically outward transverse to Beschieaufnahmenut. To the assembly of the drive rods, the Beschrangaufnahmenut by a Cover closed, with the attachment facing in the direction of the ground the Beschlagaufnahmenut pointing webs takes place, which the locking members on the outside, so along the groove side walls embrace. This will be a Expansion of the locking members under load of the drive rod prevents and at the same time ensures a fastening of the cover.

It is disadvantageous in these known espagnolette fittings that on the Clutch points of the drive rods already before mounting the drive rods corresponding locking members for guiding and fixing the drive rods must be provided so that the drive rods in the area of their Clutch points sufficiently against the bottom of Beschlagaufnahmenut are supported.

The coupling device known from DE 31 34 162 A1, by contrast, has a spacer, which stirs a sliding below a faceplate drive rod. The spacer supports the drive rod against the bottom of a Beschlagaufnahmenut, in which the drive rod of the spacer is penetrated in a slot. On the drive rod are coupling agent in Form of a pin provided, which serve for coupling with another drive rod and the coupling direction is also perpendicular to the bottom of the fitting receiving groove.

The disadvantage here is that the spacer only via the engagement in the slot of the drive rod A position assignment within the slot of the drive rod is not intended. Thus, the alignment of the spacer must be done manually. It is further disadvantageous that the spacer is set to a width which a widened portion below corresponds to each other assigning webs in the Beschlagaufnahmenut. The assembly the equipped with the spacer fitting part can therefore only be done by that this is inserted laterally into the fitting receiving groove. A usual assembly of Fittings perpendicular to the fold is not possible. Finally, the chosen one leaves Coupling device a length adjustment to the dimensions of the wing on the Spacer having fitting part not too.

The object of the invention is therefore to avoid the known disadvantages of the prior art and to provide a coupling device that is reliable and easy to handle Position securing of the drive rod allowed.

This object is achieved by the features of the characterizing part of Claim 1 solved.

The arrangement of the spacer on the drive rod is a Assembly of the espagnolette fitting created, which as usual is manageable. The longitudinal displacement of the spacer allows it in that the drive rod e.g. as with conventional Espagnolette fittings in the area of a form-locking coupling - e.g. one External teeth on the narrow sides or a group of holes a flat rectangular drive rod - can be cut to length, the Spacer in the direction of the remaining drive rod section is moved. At the same time but by the possibility of coupling the Spacer ensures that the spacer together with the Driving rod moves. An attachment of the spacer e.g. in the Beschlagaufnahmenut is therefore unnecessary and still a defined Location of the spacer causes.

As a result, a simple attachment of the spacer to the drive rod is possible because the Distance piece has latching means, which with the form-locking elements of the drive rod interact. This eliminates special attachments on the drive rod, the one Allow setting of the spacer.

A further development provides that the spacer the drive rod at least U-shaped and against a cover, e.g. one the Fastening groove occluding faceplate, supported. Thereby creates protection against buckling of the drive rod under load both in the direction of the bottom of the Beschrangaufnahmenut as well as in a opposite direction to it.

A special and advantageous embodiment provides that the Detent means consists of at least one locking projection, which in an on a narrow side of the drive rod attached teeth engages. Thereby can the spacer on the one hand in the usual today Espagnolette fittings are used in which the one drive rod has a narrow rectangular cross section in the coupling region, while the other drive rod in the coupling area carries a tooth shoe, which over-, under- or surrounds the first drive rod. The drive rod with the narrow-rectangular cross-section, points to its narrow sides usually a toothing executed over a partial length for coupling with an internal toothing of a tooth shoe on.

On the other hand, the spacer can also in other places of Provide drive rod, not in the immediate coupling area of the Espagnolettes are lying. This allows the drive rod, if necessary, between the Clutch points are supported, with only a short section of the Driving rod must be provided with a toothing.

For the most accurate guidance and a defined position of the drive rod also to reach transverse to Beschlagaufnahmenut is further provided that the spacer one dimension transverse to the direction of Beschlagaufnahmenut possesses, which is approximately the measure of Beschlagaufnahmenut corresponds to their smallest clear width. there The direction across the Beschlagaufnahmenut denotes an orientation that perpendicular to the side walls.

It is further provided that the spacer of the first drive rod is assigned, which of the positive connection element of the second drive rod is taken over or around. This will mount the spacer facilitates the drive rod, which in this case only on the already on the Espagnolette fitting mounted drive rod are pushed got to.

Finally, it is still advantageous if the spacer in one End portion of the drive rod is arranged, which has a Ablängbereich for the associated espagnolette fitting component forms, as these drive rods conditional through the cut-off region over a partial length, not e.g. on a faceplate can be performed. However, for coupling with the tooth shoe is a defined position of the drive rod advantageous.

Of particular advantage is the innovation in fittings or Mounting method as these are known from DE 19602025 C2. in this connection overlap at least the attached in the corner of the wing Espagnolette fitting components are the long components that connect before connecting the Spars were attached to a frame attached to these.

To facilitate one, in particular automatic assembly, is still provided that the spacer the drive rod against the Nut side walls supported and holds in a position parallel to the faceplate.

In the assembly of the overlapping espagnolette fittings is namely ensure that the overlapped drive rod, which in this case the Has cut area, not pressed down to the bottom of the groove and the positive connection between the drive rods therefore not concluded comes.

Further advantageous embodiments will be apparent from the figures.

Fig. 1 shows a drive rod fitting 1 a first Espagnolette fitting component 2 and second espagnolette fitting component 3. The espagnolette fittings 2, 3 consist essentially of Stulpschienen 4, 5 and drive rods 6, 7. While the drive rod 6 via their entire length of the end portion 8 has a flat rectangular cross-section has, the drive rod 7 at its end 9 with a coupling shoe 10th provided, which in the direction of the drive rod 6 and the base 11 of a Beschlagaufnahmenut 12 is open. The clutch shoe 10 is in formed essentially U-shaped and has at its parallel to each other extending leg on the inside toothings, which with a toothing 13 along the narrow side 14 of the drive rod 6 positively coupled are. The teeth 13 and the toothing of the clutch shoe 10 thus form Positive locking elements over which the drive rods 6, 7 overlap and let it be coupled. The drive rods 6, 7 are in turn under the cuff rails 4, 5 guided longitudinally displaceable and are about one - not here shown - espagnolette drive displaced.

In order to adapt the drive rod fitting component 2 to the To make dimensions of a wing of a window, the Espagnolette fitting 2 - in unmounted position - accordingly cut to length. For this purpose, the faceplate 4 and the drive rod 6 by means of a Scissors, saw or the like cut to length. This will usually be done Used devices such. B. from DE 19933890 A1. The ends of the Espagnolette fitting component 2 are in openings of the DE 19933890 A1 known device introduced, the somewhat larger are as the cross section of the drive rod 6. means z. B. hydraulically driven knife, the ends of the faceplate 4 and the Drive rod 6 separated.

In order for a coupling to be possible despite this cutting to length, the end section is 8 over a large part of its length provided with the teeth 13, so that the espagnolette fitting 2 here receives a Ablängbereich, which is within the espagnolette fitting 2 according to the Requirements and dimensions of the wing.

With regard to the design of the Ablängbereiches is to DE 2515542 C3, from which such Ablängbereich is known.

When mounting the espagnolette fittings 2, 3 on the wing is First, the drive rod fitting component 2 in the fitting receiving groove 12th arranged and fastened. If a cutting of the Espagnolette fitting 2 was necessary, this has already been done, wherein a spacer 15 disposed in the end portion 8 in the direction of the remaining and to be mounted drive rod section shifted becomes.

At a later assembly time, the drive rod fitting component 3 mounted, on the one hand, the faceplate 5 with a bent Section 16, the faceplate 4 overlaps at its end 17 and on the other the drive rod 6 overlapped at its end 18 of the coupling shoe 10 becomes. Thus, the toothing of the clutch shoe 10 and the teeth 13 of the Drive rod 6 can interlock, the spacer 15 supports the Drive rod 6 relative to the base 11 of the Beschrangaufnahmenut 12 from. As a result, the end 18 of the drive rod 6 in a through the spacer 15 predetermined distance to the base 11 held and prevented at the same time that the coupling shoe 10 during assembly, the end 18 down suppressed, the end 18 upon actuation of the espagnolette fitting, ie at a displacement of the drive rod 6, at the bottom 11 of Scrape the fitting groove.

As is apparent from Fig. 2, the spacer 15 supports the drive rod. 6 from the groove base 11 and that - as in connection with Fig. 1 - emerges in the joining direction of the teeth 13 of the drive rod 6 and the Teeth of the clutch shoe 10. In this case, the spacer 15 surrounds the Drive rod 6 U-shaped, wherein the legs 20, 21 parallel to the Grooved side walls 22, 23 run. At the free ends of the legs 20, 21 are in the exemplary embodiment successive facing latching hooks 24, 25th provided, which engage behind the drive rod 6. The dimension 26 of the Spacer 15 is chosen so that it is slightly less than the measure 27 of the smallest clear width of Beschlagaufnahmenut 12. Im illustrated embodiment, the fitting receiving groove 12 two from the groove side walls 22, 23 projecting strips 28, 29, which for Edition of the faceplate 4 serve and between which the minimum Setting distance. The faceplate 4 is flush with the fold 30th from the wing.

As can be seen from FIG. 2, the legs 20, 21 protrude beyond the Drive rod 6 so far in front that it almost to the face plate. 4 pass. As a result, the spacer 15 supports the drive rod 6 against Ausknickung perpendicular to Beschlagaufnahmenut 12, ie in the direction of Faceplate 4 from, since the locking hooks 24, 25 close to the face plate. 4 come close.

Fig. 3 shows a first embodiment of the spacer 15 in enlarged scale in a three-dimensional representation. The Spacer 15 has in the illustrated embodiment a window-like opening 40, in which the drive rod 6 mounted in the Condition is recorded. The toothing 13 having narrow side 14th is laterally facing each other locking projections 41 and 42nd facing, so that the locking projections 41, 42 locking means, with the Teeth 13 cooperate. In this case, the latching projections 41, 42 at longitudinally extending webs 43, 44 are arranged, which due to notches 45 are resilient.

Due to the latching projections 41, 42, the spacer 15 can be relative to set the drive rod 6, but nevertheless also a Longitudinal displacement, for example by hand, can be made.

FIGS. 4 and 5 show alternative embodiments of the spacers 15 shown. In the embodiment of Fig. 4, the locking projections 42, 43 in pairs at the ends of not directly with each other connected webs 46, 47 and 48, 49 arranged. This can be the Locking projections 41, 42 in comparison to the embodiment of FIG. 3rd deform more easily or move the spacer 15 easier. In which Embodiment of FIG. 5 are the locking projections 41, 42 at a perpendicular from the bottom 50 projecting web 51 and 52 of the up in the Area of the openings 40 protrudes.

All embodiments of the spacer 15 according to the figures 3 to 5 is common that all lying in the direction of displacement R edges with generous radii are provided so that upon contact of these edges with the base 11 of the Beschlagaufnahmenut 12 this does not scrub. At the same time the groove base 11 and the face plate 4 facing Surfaces with projections 53 (Figure 5) or troughs 54, 55 (Figures 3 and 4) provided to the contact surface and thus the possible friction too minimize.

Allen spacers 15 is also common that they are both in Longitudinal direction in the direction of displacement R, as well as across it are constructed by means of symmetrical, so that the assembly without confusion can be handled. The spacers 15 can be preferred made of an elastic material, for. As plastic, as moldings cost where appropriate, by adding another Friction reduction can be effected.

It is easy to see that the spacer is also beneficial in one Area of the drive rods can be used, in which no Clutch point is located.

Of course, the spacer 15 also frictionally engaged on the Driving rod 6 to be attached and only by overcoming a certain Resistance be relocatable.

It is useful, however, that the spacer 15 when inserted into the Cutting device according to DE 19933890 A1 either manually or by striking the spacer 15 against the edges of the cutting device is moved back, so that already hereby a defined distance to the end 17 of the drive rod 6 sets. Is the pushing back through the Ablängvorrichtung, so can by a suitable choice of the distance of the Opening to the knife at the same time a desired distance to the end the drive rod can be effected.

As is apparent from Fig. 2, the spacer 15 supports the Drive rod 6 also transverse to the direction of displacement, ie perpendicular to the Groove side walls 22, 23 from. As a result, the coupling of the toothings 13 and the toothing of the coupling leg 10 is facilitated. Especially at For an automated fitting installation, it is necessary that the Driving rods 6, 7 are aligned with each other.
