Description

The invention relates to a method for mounting a window or door fitting and also on a fitting set for one appropriate assembly as well as on an assembled in this way Fitting. In the following, for the sake of simplicity, only one Window fittings are mentioned, but door fittings are implicit are to be read.

When installing hardware sets on windows must be done regularly various fittings not only on the window sash or the Frame are attached, but also coupled to each other become. Such connections occur between different fittings Depending on the range of functions of the fitting, there must be a relatively large number of them can be manufactured quickly and effectively. In particular, each should Depending on the application, there are no-play connections, for example to power and Motion transmission, and / or capable of adjustable connections can be created. Furthermore, the fittings should be with regard to their choice of materials and shape should be as simple as possible.

The invention is therefore based on the technical problem, an improved one Assembly procedure for a window fitting (or door fitting) and one matching fitting set or a correspondingly mounted fitting specify.

The invention relates to a method for assembling a fitting for a window or a door, in which two fitting parts are connected to one another by bringing the fitting parts closer together,
characterized in that when the fitting parts approach each other, an initially flowable mass is brought to form-fit with the two fitting parts, and then the mass hardens, whereby the two parts are positively connected by the hardened mass,
as well as a fitting set for a window or a door, designed for the above assembly method, with the two fitting parts to be connected to one another and the flowable, curable compound for connecting the fitting parts, the fitting parts being designed for a connection to one another by positive locking with the hardened compound,
and finally on a fitting of a window or a door, in which the two fitting parts are connected with the assembly method described above, the fitting parts each being in positive engagement with the hardened mass connecting the fitting parts.

The basic idea of the invention is to connect between two Fitting parts with the help of a curable compound manufacture. This mass is flowable before the connection is made, is brought into a positive connection with the two parts in this state and then cured. As a result, the two fittings are together coupled. The hardened mass can only be responsible for the two fittings in an otherwise independent from her To keep positive or frictional connection with each other, but it can also Connect the two parts yourself (exclusively).

Such a connection is in terms of material and requirements Shape of the fittings is extremely simple and can also without complicated movements or other assembly steps easily made become. It is also usually free of play, which is the case with conventional ones Solutions are often not the case.  

The assembly method according to the invention is particularly simple when the movement of the two fitting parts to their approach or installation is used at the same time to each other, the positive engagement of the mass with the Manufacture fittings, if so to speak the flowable mass is pressed into the form-fit between the fittings.

The term "flowability" is to be understood in this invention in such a way that the mass with a realistic effort in the form fit manufacturing form can be brought. It can be a actual liquid, but also a viscous or viscous substance act.

To the distribution and deformation of the flowable mass between the Hardware components during assembly with as little work as possible allow, according to the invention it is particularly provided that the flowable Attach the mass in a container to one of the fittings. The Container should be designed so that it is only by the Approach movement of the other fitting part is opened. This can an opening device can be actuated by the other fitting part; at the However, it is simplest if the container is replaced by the other fitting parts itself opened, in particular crushed. To do this offer Plastic bubbles as containers, one for the storage of the flowable mass have sufficient stability, but by Press on the other fitting part burst or at predetermined breaking points rip. There can also be tips or cutting on the other Fitting part may be provided to open this container facilitate.

Since the mass emerging from the opened container is usually one When exposed to air, it lends itself to a substance, usually an appropriate plastic, to be used only by the Air contact hardens. Of course, other curing reactions can be used, for example by heat application, light irradiation  or by adding liquid. It is also possible to have two To provide components of the mass side by side, before or at the Deforming the mass come into contact with each other or at least partially mixed together so that a curing reaction can expire. A second can of course be used for this Plastic bladder or generally a second container can be provided.

The connection produced in the manner described is preferred a detachable connection. For this purpose, the positive connection should be designed so that the fittings again from the positive connection with the hardened mass can be pulled out, albeit under a certain Effort. The should be formed by the hardened mass Do not break molded part, but can be recycled. In particular, provision is made for the adhesive forces to be as low as possible allow between this molding and the two fittings, so not too great an adhesive effect of the molded part a later separation made unnecessarily difficult. For use cases where the connection should be as stable as possible or later separation is no longer essential, Of course, a strong adhesive substance can also be used especially an actual glue.

A particularly simple design of the hardware components for manufacture a positive connection consists in a through hole, for example in one Drilling through a piece of sheet metal. The flowable can flow into this through hole Mass at least partially enter and after hardening a pin in the Form through hole. Another cheap option is one Indentation, for example on a side edge of a piece of sheet metal or as a blind hole in one surface. Here, too, the flowable mass can at least partially penetrate and create a positive fit as a bolt. Both through holes and indentations are in the for Fitting parts in question manufacturing processes unproblematic and can be produced at no great additional cost.  

In a somewhat more complex embodiment, at least one of the Hardware parts a set of teeth to create a positive connection. The Teething has the advantage that after releasing the positive connection the surface remaining as a negative impression of the toothing of the molding formed by the hardened mass with a Position offset can be brought back into engagement with the toothing. This means that the connection can still be set even after the mass has hardened, namely in the toothing corresponding to relatively small steps. If only relatively large setting steps are necessary, several can be Indentations or holes for the engagement of a pin of the Forming come into consideration, fulfill this task. During the Production of the positive connection, i.e. during the flowability of the mass, an adjustability is also independent of those described above Measures usually given by the fluidity of the mass moving the two fittings against each other allowed.

If the two fitting parts to be connected to each other, outer surfaces have in the state of connection of the two fitting parts are plane-parallel to each other and could come into contact with each other, so the invention provides as a preferred embodiment, here between one Provide spacer element that prevents this system and thus a ensures sufficient material thickness of the hardened mass. In order to can the cured mass and the connection between the two Hardware components are stabilized. This spacer can be a Protrusion on one of the fitting parts or a separate element, for example an element of a plastic bladder or another Container of the curable mass. In particular, it can Spacer element should also be designed so that when opening the Plastic bubble helps by making the tip or cutting edge mentioned above having.

Similarly, in other situations it can be ensured that a sufficient material thickness for the cured mass between  the fittings remain, for example, when the end of a Espagnolette piece in one shoe on the other fitting part is recorded. It is preferable to ensure that the width the connecting rod piece between the thighs of the shoe is not so big is that between the outer edges of the drive rod and the Shoe thighs too little space remains. By appropriate Dimensioning of the drive rod width can be provided here. At the at preferred use of standard components from Espagnolette fittings (compare embodiment) can do this Drive rod width can be reduced somewhat.

A preferred application for the invention is in the coupling various driven parts of an espagnolette fitting, for example different drive rod pieces or one Espagnolette piece with the moving part of a corner drive.

Due to the particular simplicity of the assembly method according to the invention this also lends itself to automated fitting assembly, which In view of the increasing cost pressure in this area from always is more important. Assembly machines have with conventional Couplings between driven parts of espagnolette fittings, the usually done with complementary teething, having difficulties with the sufficiently careful and precise production of this intervention, so that expensive manual labor is used here.

This is already the case with this automatic assembly in particular explained feature of importance, the flowable mass in a container (or a plurality of containers) to attach to the fittings, so that already the assembly of the hardware parts or the containers opens and, if necessary, those to be brought into contact with each other Brings components together and then causes the deformation. you This saves, above all, the expenditure on equipment for a machine Introducing or applying the flowable mass. Of course that forms  Attach the container or containers to the fitting parts manual assembly is a major advantage.

As already mentioned at the beginning, the invention also relates to one for the fitting set described and a appropriately mounted window fittings.

In the following, the invention is illustrated by an embodiment explained in more detail, the features disclosed thereby also individually or in other combinations may be essential to the invention. In particular is the foregoing and the following description of the invention both in With regard to their procedural aspect as well as their device aspect interpret.

Fig. 1 is a cut-away view showing a fitting set of the invention;

FIG. 2 shows a fitting according to the invention, namely the fitting set from FIG. 1 in the assembled state;

in which Figs. 1 and 2 together illustrate assembly process of the invention.

FIG. 3 shows a perspective illustration of a variant similar to FIG. 2 as a second exemplary embodiment.

In Fig. 1, the respective end pieces of two fitting parts 1 and 2 of a window fitting set are shown. These are the ends of two sections of the driven connecting rod of a rotating / tilting fitting set facing each other in the desired mounting state.

The fitting part 1 has at its end a toothed shoe which is open at the top in the sense of FIG. 1 and which has a claw-like cross section as seen transversely to the longitudinal direction of the fitting part 1 and which is numbered 3. The toothed shoe 3 has teeth 4 on the respective inner side of the legs of the claw-like cross section.

So far, a conventional drive rod piece with a conventional tooth shoe could be used. However, the coupling between the fitting part 2 and the fitting part 1 should not be carried out via a conventional external toothing of the fitting part 2 , which is also not present here, but rather through the inventive deformation of a flowable mass at the beginning of the assembly process. This mass is provided within the toothed shoe 3 on its bottom in a pillow-like plastic bladder and is designated by 5. The deformable mass 5 is enclosed in this bladder for storage, ie it does not harden as long as it has no air contact due to the inclusion in the bladder. In addition, the bladder is fastened to the bottom of the toothed shoe 3 by a drop of adhesive or by being clamped between the rows of teeth and thus forms part of the fitting part 1 with regard to the storage and transport of the fitting parts to the installation location.

During assembly itself, the fitting part 2 is now approximated to the fitting part 1 such that the (left in FIG. 1) end of the fitting part 2 can be inserted into the toothed shoe 3 . It should be noted that there is no tooth engagement because the fitting part 2 has no external teeth. Rather, through holes 6 are provided at suitable points in the fitting part 2 , which are used to produce the positive connection with the deformable mass 5 .

When the end of the fitting part 2 has been inserted into the toothed shoe 3 , the fitting part 2 can be pressed firmly against the bottom of the toothed shoe 3 by an automatic assembly machine or by manual hand pressure, so that the bubble of the mass 5 bursts and this exits. It is distributed by the pressure of the fitting part 2 on the bottom of the toothed shoe 3 within the toothed shoe 3 , flows into the through holes 6 insofar as these lie in the area of the toothed shoe 3 , and is at least partially distributed in the area of the internal teeth 4 of the toothed shoe 3 .

When the compound 5 hardens in this state, it is in positive engagement with the through holes 6 it detects with the fitting part 2 and with the internal teeth 4 with the toothed shoe 3 and in this sense with the fitting part 1 .

If the mass 5 has not risen so far beyond the upper edge of the through holes 6 that it covers this upper edge, the fitting part 2 can be released from the mass 5 after the deformable mass 5 has hardened by being pulled strongly upwards. In addition, the mass 5 can be lifted out of the shoe 3 again. It is a prerequisite that the adhesive forces between the mass 5 and the toothed shoe 3 or between the mass 5 and the fitting part 2 are not too high. In addition, the molded part formed by the mass 5 can then be detached from the fitting part on which it got stuck. This gives the possibility to carry out subsequent fine adjustments, for example by fitting the fitting part 2 instead of the outermost two through holes with the molded part from the mass 5, with the second and third through hole seen from the left in the figures. Alternatively, this molded part can be reinserted into the internal toothing 4 of the toothed shoe 3 . A combination of both options can be used to carry out a rough and fine adjustment.

In addition, the position of the coupling between the fitting parts 1 and 2 can of course be infinitely and finely adjusted before the hardening of the mass 5 in that the fitting parts 1 and 2 are displaced in their longitudinal direction against one another, the deformable mass 5 of this movement being viscous Deformation contributes.

A major advantage of the invention is compared to, for example a conventional tooth connection in that the invention Connection is completely free of play. In addition, as I said, it is in the process of being assembled infinitely adjustable and finally for automated assembly much more suitable than tooth connections.

It is clear that instead of the internal toothing of the toothed shoe 3 , an external toothing could also be provided on the fitting part 2 . In addition, the bladder with the mass 5 could of course be viewed as a single fitting part and inserted before assembly. However, the bladder could also be glued to the end of the fitting part 2 , where, however, it would be less well protected against destruction before assembly than inside the toothed shoe 3 .

If the bladder 5 is made relatively stable, it can be difficult to open it by pressing the fitting part 2 manually. Then a tip or edge can be provided on the underside of the fitting part 2 (in the sense of FIG. 1). Such a tip or edge could also be provided within the toothed shoe 3 , positioned approximately such that it pushes into one of the through holes 6 after the fitting part 2 has been inserted. In addition, the bladder can of course also be opened manually with a screwdriver end, a knife or a nail in order to then insert the fitting part 2 .

Instead of the through holes 6 , lateral indentations can also be provided, which - depending on the material - can offer manufacturing advantages.

In this embodiment, the mass 5 is a plastic that hardens after contact with air. Two bubbles with two components of a common curing system can also be provided, or other activators can be used. Of course, light or heat can be used to support curing. However, the simple air contact as an activator is the practically simplest solution.

The person skilled in the art knows a large number of suitable materials for mass 5 . For example, all those materials that can be used are those that form sufficiently hard curing commercially available adhesives that are not well suited for the bonding of metals.

The adhesion between the mass 5 and the toothed shoe 3 or the fitting part 2 can also be reduced in that the corresponding surfaces of the fitting parts are lightly greased or otherwise coated after their manufacture.

Fig. 3 largely corresponds to Fig. 2, the perspective view having a slightly different angle. However, a second exemplary embodiment is shown here, in which the toothed shoe 3 'and the fitting part 2 ' (connecting rod piece) are modified compared to the first exemplary embodiment.

On the one hand, the fitting part 2 'is reduced in width in the area of possible engagement in the toothed shoe 3 ', specifically by a step 8 in the lateral outer edges. Here it is assumed that the fitting part 2 'is, apart from the absence of external teeth, a standard coupling piece of a connecting rod fitting, as is the toothed shoe 3 or 3 '. As a result, the width of the connecting rod piece 2 fits exactly without the width reduction, that is to say in the first exemplary embodiment in FIG. 2, between the outer legs of the toothed shoe 3 . By inserting the paragraph 8, there remains an intermediate space corresponding to the overall step height of the paragraph 8 , which ensures a correspondingly increased material thickness of the hardened mass 5 between the toothed shoe 3 'and the fitting part 2 ', regardless of the exact longitudinal position. For this purpose, step 8 is sufficiently far from the end of the fitting part 2 '.

In addition, the toothed shoe 3 'has a projection in its bottom region, that is to say on the upper outer surface of its base in the sense of the figure (not visible in FIG. 3), which also extends between the underside of the fitting part 2 ' and the upper side of this base of the toothed shoe 3 'ensures a corresponding space and thus an increased material thickness of the hardened mass 5 . The space is designated by 7, but the actual spacing element cannot be seen. This spacing element is preferably a protrusion on the toothed shoe 3 ', which is in any case formed regularly as a zinc die-cast part, and in this respect can be supplemented with such a shaped element with little effort. Alternatively, however, a projection could also be provided on the underside of the fitting part 2 'or a separate element, for example an element of the plastic bladder containing the mass 5 . A protrusion on one of the two fitting parts, for example a protuberance at the base of the toothed shoe 3 ', can be pointed or sharp at the top, so that the opening of the plastic bladder is made easier when the fitting parts 1 and 2 ' are brought together.

Otherwise, the second embodiment does not differ from that already explained first embodiment.
