Description

The invention relates to a driver connection according to the preamble of Claim 1.

Such connections are needed above all for window and door fittings, the general problem is that the frame or door thickness quite different can be predetermined. To counter this, for example, in DE-U1-1 705 743 described a pusher pin or mandrel, which is firmly connected to a handle becomes. A balance of door thickness deviations should be with a longitudinal in the Dorn / pusher pin embedded coil spring be possible by the side Slots in it is accessible. To set a counter-grip is a retaining pin across driven through the handle neck and through the spring whose turns are so dense should lie together, that the retaining pin is wedged. Because this but with his Ends are always visible and may survive, this is not aesthetically satisfying Solution; also a risk of injury can not be ruled out. In addition, the requires Mounting greater effort, and it depends on the spring design, whether the retaining pin is collectable at all and then unfolds its function.

DE-C2-197 07 836 also discloses a pusher connection with a lock nut piercing mandrel, which is designed as a square pin. He is tight with his neck a first door handle connected and carries at its other end, a second Door handle facing, pinned with the drive pin or mandrel outer sleeve. In the provided with an inner sleeve neck of the second handle is a spring-loaded Bayonet closure, which, however, does not allow mandrel length compensation.

Generally, a fitting with a stopper body, e.g. a rosette, on the Outside or profile top of a window or a door in height of an inner Gear or lock nut mounted. The arrangement of the required Mounting holes is standardized in terms of the location of a square, the nut than Interspersed. Different window profiles or door thicknesses, however, require Unequal axial distances of the nut from the stop surface. The conventional devices contribute nothing to it, the so-called Vorstehmaß the thorn or Square pin with different frame or door thicknesses the same size to always to secure the engagement in a gear or lock nut. As a result, one is previously forced to produce a variety of mandrel or pin lengths and to store, which means considerable logistical effort.

Therefore, there is a need to address the aforementioned and other disadvantages of the prior art Technology to overcome. The invention aims, with the simplest possible means a Adjusting the effective mandrel or pin length to the given windows or doors to reach an object. Here, the full functionality of the fitting be permanently guaranteed.

Main features of the invention are specified in claim 1. Embodiments are The subject matter of claims 2 to 14.

In a driver connection for window and door fittings with a stop body, e.g. a rosette, which has a bearing bush for the neck of a handle and on a stop surface of a window or a door in the amount of an inner Gear or lock nut is mounted so that a trained as a square, with an end in a square hole of the handle neck seated driving pin when plugging in the bearing bush with its other end form-fitting in a gegengleiche Recess of the nut engages, the invention provides according to claim 1, that in the handle neck square hole slidably inserted one end of the drive pin is that the other driving pin end at one point, the maximum depth corresponds to the nut, at least one notch, punching or the like. and that the latter can be latched to the nut. Regardless of different frame or Door thicknesses, the axial fixing of the driving pin is therefore through the notch, Punching or the like. always in the exact right distance to the gear or lock nut recess.

An important feature is that the driving pin regardless of the thickness or strength of the respective window frame or the respective door a fixed Length has. This is a decisive factor in terms of manufacturing and warehousing Progress achieved.

The notch, punching or the like. is advantageously arranged on an edge of the driving pin, so that a striking catch on the nut takes place. It is even better if at least two notches, punched holes or the like. at adjacent edges of the driving pin are present, which facilitates reliable latching, especially when the or each notch, punching or the like. locked on the edge of a Nutbegrenzungswand is.

An important embodiment of the invention is that the driving pin sitting under the interposition of a spring in the square hole. The spring can be a compression spring be, especially a coil spring. It causes the driving pin to continue is pressed under axial spring force to the gear or lock nut out and into it always protrudes sufficiently.

Although it is apparent from DE-U1-94 15 966 in a closure gear an operating lever, in the neck of which sits a compression spring which is provided with ball ends Clutch piece loaded axially, so that during assembly a lateral offset to a lock nut can be compensated out. An axial length compensation for different Frame or door thicknesses is not provided. This also applies to the in DE-C-35 322 proposed construction of a releasable door lock connection, the has two grip buttons. A compression spring braced here in sections with square profile provided, otherwise round pin in the one handle knob, but without one Vorstehmaß would be observed. And also with a polygonal Wechselschloßstift to DE-C2-28 31 514, wherein a lock nut engages behind by a stop end piece is, between the nut and the handle neck end is a coil spring arranged. But it only serves to compensate for tolerances of Schloßnußdicke and not for the variable length change of the square pin. The invention is over the aforementioned prior art clearly.

Advantageously, the spring has a wide end which can be clamped in the square hole, so that their function is easily secured. The other end can be so tight be designed so that it jams on a pin of the driving pin and therefore always is held reliably, which contributes positively to the functionality of the compound.

In another design, it is provided that the driving pin with intermediate position a reducing sleeve frictionally slidably seated in the square hole. The sleeve is in fitted the handle neck fed and is based on the frontal collar with a Flange axially. The inner contour of the reducing sleeve is on the cross section of the driving pin adjusted so that it is displaced by force. elastic Tabs that protrude into the sleeve interior provide some slippage and also sufficient smoothness for sure. Advantageously, the Reduzierhülse a precise dimensioned injection molded part, which is easy to assemble and the required mobility of the driver pin permanently.

It can be seen in Fig. 1 to Fig. 2b, a handle neck 12 with a centrally arranged Square hole 14 and a front collar 15. A drive pin 18 is a square formed and has at its lower end 48 a pin 19 on which a tight End 56 of a spring 52 jams. Its opposite end 54 is widened, so that it can be clamped in the square hole 14. This spring design acts as well Fall-out and transport security. The driving pin 18 has at a distance t of its upper end 58 (in Figs. 1 to 2b) a point 36, where at least one notch 50, Punching or the like. is arranged on an edge 38 and 39, respectively.

Fig. 3a to Fig. 5b show how the assembly of a handle 10 of a rosette 20th axially fixed / rotatably mounted on a frame profile 30 is going on. The latter is with holes 32 in a predetermined hole pattern (Fig. 3a) provided on the shaping the rosette 20 is tuned. This has in the middle a bearing bushing 22 (FIG. 3b) and, with respect to the abutment surface 34 of the profile 30, provided with screw holes 26 Cam 24, which can be covered by a pivotable cover plate 28.

It can be seen that the one end 48 of the driving pin 18 in the central bore 32 of the Frame profile 30 is to be inserted, wherein the cams 24 in the outer bores 32 of the Engage profile (Fig. 4b, 5b) and then with screws 27 (Fig. 5b) are determined. The anchoring takes place in threaded holes 43 of a gear insert 42, the a gearbox 40 holds. This is provided with a recess 44 (Fig. 3b), the which receives one end 48 of the driving pin 18 in a form-fitting manner.

In the preassembled state (Fig. 3b), the spring 52 is relaxed. Will now be the opposite End 48 of the square pin 18 inserted into the recess 44 of the nut 40 (Fig. 4b), so locks the or each notch 50 on the adjacent Nutußenzungswand 46. Thus, the engagement of the end 48 of the driving pin 18 in the required trough depth t guaranteed. If now the rosette 20 is struck hard, by their cams 24 driven into the holes 32 and 27 by means of screws be attached, the other end 58 pushes deeper in the square hole 14, wherein the spring 52 is compressed (Fig. 5b). This causes a constant Pressure of the driving pin 18 in the nut 40 into it.

Fig. 6 to Fig. 7b show a modified design in which the driving pin 18th is received with its one end 48 in a Reduzierhülse 60, in the Square hole 14 is fitted fully, with a flange 62 on the collar 15 of the Grip neck 12 is supported. Between the Reduzierhülse 60 and the driving pin 18th is a sliding friction fit such that the pre-assembled state (Fig. 7) further outstanding pin 18 when force with its inner end 48 deeper in the square hole 14 can be driven in (Fig. 7b). This is the Reduzierhülse 60 expediently provided with (indicated in Fig. 7a) projections, which a elastically yielding inhibition of the possible sliding movement.

The invention is not limited to one of the above-described embodiments, but variously changeable. For example, the driving pin 18 does not have to be in one piece be; it can be composed of two equal halves, if so notches 50 are present only at the defined point 36 of the longitudinal edges 38, 39 are. Also come other springs 52 as drawn into consideration. In the alternative design without axial spring in the reducing sleeve 60 inwardly directed Projections as elastic barbs, ribs or the like. be formed, the e.g. With a transverse corrugation of a driving pin end 48 interacting detent.

It should be noted that a driver connection according to the invention for window and Door fittings has a stopper body 20 having a bearing bush 22 for the neck 12th a handle 10 and on a stop surface 34 of a window frame 30 and a door in the amount of an internal gear 38 or lock nut so mountable is that a square 18 with one end 48 in a square hole 14 of the handle neck 12th slidably seated and plugged into the bearing bush 22 with his other End 58 positively engages in a gegengleiche recess 44 of the nut 40, wherein at least one notch 50, punching or the like. can be locked on the nut 40. Of the Mitnehmerstift 18 has irrespective of the frame or door thickness d a fixed Length ℓ. At least one notch 50, punching or the like. is at an edge 38; 39 the driver pin 18 is arranged and latched to a Nutbegrenzungswand 46, especially at the edge. The driving pin 18 is located in a preferred Embodiment in the square hole 14 under axial pressure of a spring 52, especially one Coil spring which is clamped therein with a wide end 54 and appropriate clamped with a narrow end 56 on a pin 19 of the driving pin 18. alternative the latter can be frictionally arranged, displaceable in one Reduction sleeve 60, which sits in the square hole 14 of the neck 12 under interference fit and is axially supported on the frontal collar 15 with a flange 62. The inner contour the e.g. made of plastic reducing sleeve 60 is on the cross section of the driver pin 18 is adjusted so that this displaced upon application of force is what the sleeve 60 may have inwardly directed resilient protrusions.

All arising from the claims, the description and the drawing Features and advantages, including design details and spatial arrangements, can be essential to the invention both for themselves and in a wide variety of combinations be.
