Description

The present invention relates to a fitting arrangement comprising a first and a second fitting element for arrangement on opposite sides of a door leaf or a window sash.

Such fitting arrangements are basically known and dress, for example, locks or door handle elements, the fitting arrangements should be installed as simple as possible and especially without tools in doors and windows. Furthermore, there is a requirement to be able to provide such fitting arrangements even in a comparatively flat embodiment and without visible fasteners. In addition, complicated milled on the door should be avoided.

Fittings are, for example, rosettes or door plates, rosettes are usually designed to be smaller than door plates and cover, for example, only a lock or the area of a guide bearing a door handle. Door plates on the other hand are larger cover plates with recesses in a lock area and in the area of a guide bearing of a door handle.

To ensure easy mounting of the opposite fitting elements of a fitting arrangement, it is for example from the DE 20 2009 008 754 U 1 known to provide a connecting piece between the fitting elements, which the fitting elements by means of a Gearing mutually fixed together and thus attached to a door leaf or window sash. In order to enable a smooth assembly, known connecting elements are molded in particular from a plastic material, wherein the connecting elements have a plurality of teeth which engage with teeth of usually metallic fastening elements of the fitting elements.

A smooth installation is possible in particular by the configuration of the connecting element made of a plastic material, since the plastic material is deformable and thus allows insertion and locking of the connecting elements in the metallic fasteners with slight deformation of the connecting elements.

Disadvantageously meet hardware assemblies that comprise a formed from a plastic material connecting element, not the usual fire safety requirements. In case of fire, the plastic material would melt and thus the attachment of the hardware components are destroyed.
In addition, the connection of the fitting elements using plastic material is often not stable enough, so that the compound loosens or even loosens in an undesirable manner. Furthermore, it is disadvantageous that the latching can usually be done only once using plastic material, since the plastic material wears off during Verrastungsvorgang.

The invention has for its object to provide a particular flat fitting arrangement, which can be mounted on the one hand with little effort and ensures compliance with current fire protection requirements, a stable and permanent connection of the individual elements of the fitting arrangement.

The solution of this object is achieved by a fitting arrangement with the features of claim 1, and in particular in that the first fitting element at least one vertically projecting locking bolt with a plurality of axially successive elevations and depressions and the second fitting element a vertically projecting detent sleeve with a single, inwardly projecting Locking projection comprises, wherein the locking pin in the latching sleeve by means of the locking projection can be fixed.

The fitting arrangement according to the invention is thus characterized in that the first and the second fitting element of the fitting arrangement are fastened to a door leaf or a window sash by means of a locking sleeve cooperating with a locking bolt. The detent sleeve thereby comprises only a single detent projection which engages with the detent pin. By using a single locking projection only a cogging torque of the individual latching projection must be overcome during assembly of the fitting assembly. It is thus possible to assemble with little effort.

Advantageous embodiments of the invention are set forth in the subclaims, the description and the drawings.

The latching projection of the latching sleeve is subdivided into a plurality of partial projections in one embodiment of the fitting arrangement according to the invention, wherein all the partial projections have the same distance from the second fitting element. Consequently, the latching projection does not have to be continuous or circumferential, but may also have interruptions. This leads to a reduction of the effective length of the locking projection and thus also to a reduction in the Assembly to be overcome cogging torque. The assembly is thus further simplified by the provision of partial projections.

According to a particularly advantageous embodiment, the latching sleeve and / or the latching pin are or are formed from metal. In this way, common fire protection requirements can be met. The cogging torque to be overcome in one embodiment of metal is significantly greater in comparison with a version made of a plastic material due to the lower flexibility of the metal. As a result, in the case of fitting arrangements according to the prior art, the force to be expended during assembly would be significantly increased, which may even lead to assembly that is no longer possible at all using muscle power alone. A simple, easy and manual installation is thus only possible by the locking sleeve according to the invention, which significantly reduces the assembly force by providing only a single locking projection. In an alternative embodiment, however, the detent sleeve and the detent pin can also be made of plastic, in particular of heat-resistant plastic. It is also possible to produce one of the two parts of detent sleeve and locking pin made of plastic, in particular of heat-resistant plastic and the other metal.

Due to the generally made of metal-shaped locking sleeve according to the invention, which comprises only a single locking projection, the previously incompatible requirements for easy and simple installation, to a reliable and permanent connection of the individual elements of a flat fitting arrangement and to the fulfillment of fire protection requirements are compatible ,

According to a further embodiment, the latching sleeve is formed substantially hollow cylindrical and the latching projection circumferentially on a Inner wall of the latching sleeve, in particular in the region of a first end of the latching sleeve arranged. A provided with a plurality of axially successive projections locking pin can thus penetrate into a hollow cylindrical interior of the locking sleeve and is determined by the arranged there, with the projections of the locking bolt cooperating locking projection in the particular desired depth in the locking sleeve. By the penetration of the locking bolt in the locking sleeve of the locking pin is also aligned axially with the locking sleeve. This allows, inter alia, a corresponding orientation of the fitting elements.

If the latching projection is arranged in the region of a first end of the latching sleeve, latching takes place already when the latching pin has only penetrated into the region of the first end of the latching sleeve. This is particularly advantageous when mounting the fitting arrangement according to the invention, since the first and second fitting element are already fixed to each other when the locking pin has penetrated even slightly into the locking sleeve. In addition, due to the present invention only a locking projection of the locking sleeve - unlike the prior art - regardless of the penetration depth always generates the same cogging torque. The safety of the attachment of the fitting assembly is thus not very advantageous from the depth of penetration of the locking bolt in the latching sleeve from. Furthermore, the locking bolt material-saving just be formed so long that it extends in the assembled state, for example, in a thick door leaf only up to the locking projection in the detent sleeve.

Advantageously, the locking sleeve in a region of the locking projection, the longitudinal axis of the locking sleeve crossing slots, in particular two arranged at an angle of 90 ° slots. The slits divide the hollow cylindrical latching sleeve in the region of the latching projection in a plurality of segments. These segments make it possible for the latching projection or the partial projections of the latching projection then present during insertion of the latching bolt to be pressed more easily in the radial direction to the outside. The partial projections are thus easier to move. The cogging torque and thus the applied mounting force are thus further reduced by the slots, wherein the mounting force decreases with the length of the slots. In particular, two mutually perpendicular slots are used, which divide the locking sleeve in the region of the latching projection in four segments. This is production technology, for example, by one or more cutting operations particularly easy to effect.

Furthermore, the latching sleeve may comprise a thread which is arranged in the region of a second end opposite the latching projection such that the latching sleeve can be screwed onto a fastening bolt projecting vertically from the second fitting element. The latching sleeve can thus be fastened in a simple manner by screwing to the respective fitting element. The screw fixes at the same time the spatial orientation of the locking sleeve.

Likewise, it is possible that the latching pin in the end portion facing away from the latching sleeve comprises an extension piece with an internal thread, whereby the latching bolt can be screwed to a fastening bolt protruding perpendicularly from the first fitting element. In particular, both the locking bolt and the locking sleeve can comprise an identical internal thread, whereby locking bolt and locking sleeve can be screwed to identical fitting elements or identical fastening bolts of fitting elements. Thus, the fitting arrangement according to the invention are formed on the basis of two identical fitting elements.

According to a preferred embodiment, the fitting arrangement according to the invention comprises at least two snap-on sleeves, which can be screwed to the second fitting element by a respective fastening bolt and in each of which a latching bolt can be fixed. The use of at least two snap-on sleeves determines the spatial arrangement of the two fitting elements against each other clearly defined. A twisting of the fitting elements against each other is therefore no longer possible.

Preferably, the locking projection is formed by two mutually running bevels, the closer to a first end of the locking sleeve slope has a smaller angle with a longitudinal axis of the locking sleeve than the end of the locking sleeve farther lying slope. This means that when inserting the locking bolt into the locking sleeve, the elevations and depressions of the locking bolt along a relatively flat ramp over the locking projection are moved away, which is possible with little effort. For example, this smaller angle may be in the range of about 45 °. A - usually not required - releasing the connection of the locking sleeve of the locking bolt, however, is made more difficult by the larger angle and thus steeper ramp of the end of the detent sleeve facing away slope. Such a second and larger angle may, for example, be in the range of approximately 60 °. According to the invention it is thus possible to combine a low assembly force with a high holding power.

According to a further embodiment, the successive elevations and depressions of the locking bolt by a thread, in particular formed an M3 thread. A threaded having locking bolt is manufacturing technology particularly easy to produce.

1. a) Herstellung eines zylinderförmigen, metallischen Rohlings;
2. b) Einbringen einer mittig in axialer Richtung verlaufenden ersten Bohrung, mit einem ersten Bohrdurchmesser, welcher kleiner als der Durchmesser des Rohlings ist, wobei sich die erste Bohrung im Wesentlichen über die Länge des Rohlings erstreckt, der Rohling jedoch nicht zur Gänze durchdrungen wird;
3. c) Einbringen einer mittig in axialer Richtung verlaufenden zweiten Bohrung, mit einem zweiten Bohrdurchmesser, welcher kleiner als der erste Bohrdurchmesser ist, wobei die erste und die zweite Bohrung gemeinsam ein Durchgangsloch in axialer Richtung durch den Rohling erzeugen, welches ein auf den zweiten Bohrdurchmesser verjüngtes Ende aufweist;
4. d) Einbringen von zwei senkrecht zueinander und senkrecht zu der axialen Richtung verlaufenden Schlitzen im Bereich des verjüngten Endes;
5. e) Schneiden eines Innengewindes im Bereich eines dem verjüngten Ende gegenüberliegenden Endes;
6. f) Ansenken des verjüngten Endes des Rohlings.

The invention further comprises a method for producing a fitting latching sleeve for a door or window fitting, comprising the steps:

1. a) production of a cylindrical, metallic blank;
2. b) inserting a first bore extending centrally in the axial direction, having a first bore diameter smaller than the diameter of the blank, wherein the first bore extends substantially the length of the blank but the blank is not fully penetrated;
3. c) inserting a second axially extending second bore, with a second bore diameter, which is smaller than the first bore diameter, wherein the first and the second bore together produce a through hole in the axial direction through the blank, which is a tapered to the second bore diameter End has;
4. d) introducing two slits perpendicular to each other and perpendicular to the axial direction in the region of the tapered end;
5. e) cutting an internal thread in the region of an end opposite the tapered end;
6. f) countersinking the tapered end of the blank.

Consequently, with the method according to the invention, a latching projection is essentially created by producing a protrusion of material (the latching projection) in the region of a meeting of two holes with different diameters.

According to a further embodiment, the blank has a diameter of 5 to 9 mm, in particular 6.7 mm. The first bore diameter may be between 2 and 5 mm, in particular approximately 3.2 mm and the second bore diameter between 2 and 5 mm, in particular approximately 2.6 mm. The drilling of the first bore occurs e.g. with a point angle of greater than 90 °, preferably about 118 °, and countersinking with a point angle which is less than the point angle when drilling the first hole and in particular about 90 °.

As already described above, the locking projection preferably comprises the material projection between two holes with a bore diameter of 3.2 mm and 2.6 mm. In addition, the above-mentioned different angles of the slopes are achieved by different point angles during drilling or countersinking. By an appropriate choice of the drill or countersink, the angle of the bevels of the locking projection can be easily varied in the production process. The respective mounting or holding force can be adjusted in this way. Alternatively, the angles may be adjusted to a harder / less flexible or softer / more flexible material of the detent sleeve to achieve a constant mounting and / or holding force. Likewise, as described above, the length of the slots may be changed to accommodate the mounting and / or holding force.

It should be noted that the sequence of the method steps according to the invention is essentially freely selectable. Thus, although initially a cylindrical, metallic blank must be produced, all following steps (b to f) can then be carried out in any order on the blank.

two embodiments of the fitting assembly according to the invention in conjunction with door handle elements in three-dimensional view.

Fig. 1 shows a schematic of a locking sleeve 10 according to the invention. This comprises a cylindrical, metallic base body 12 in which a first bore 14 is introduced, which extends substantially over the entire length of the base body 12, but does not penetrate the base body 12 in its entirety.

At the not penetrated by the first bore 14 end (in Fig. 1 right), the base body 12 comprises a second bore, which has a smaller diameter than the first bore 14 and which is extended by a countersink 16. In the region of the transition between the first bore 14 and the countersink 16, a circumferential latching projection 18 is arranged, which is created by the inventive design of the first bore 14 and the second bore with countersink 16.

The locking projection 18 is formed on the one hand by a slope of the countersink 16 and on the other by a slope of the first bore 14. As can be seen, the slope of the countersink 16 with a longitudinal axis of the locking sleeve 10 has a smaller angle than the slope of the first bore 14th

In the region of the detent projection 18 opposite end of the detent sleeve 10, the base body 12 includes an internal thread 20 which connects to a countersink 22.

Fig. 2 shows a schematic three-dimensional representation of the locking sleeve 10 according to the invention. In particular, it can be seen that the base body 12 comprises two arranged at an angle of 90 ° slots 24a, 24b, which intersect the longitudinal axis of the locking sleeve 10 and are arranged in a region of the locking projection 18.

The slots 24 divide the locking projection 18 into four partial projections 19, of which three in Fig. 2 are visible. The partial projections 19 have an equal distance from the ends of the main body 12 of the latching sleeve 10.

The slots 24 also divide the main body 12 in the region of the partial projections 19 into four segments 25, wherein the segments 25 allow for an action of a radially outward force on the partial projections 19, an easier retraction of the partial projections 19.

Fig. 3 schematically shows a spatial arrangement of a fitting assembly according to the invention in an exploded view. In this case, two latching sleeves 10 are arranged between a first fitting element 26 and a second fitting element 28.

The second fitting element 28 comprises two threaded bolts 30 provided with a thread and a door lever bearing 32. The snap sleeves 10 can be screwed to the threaded bolts 30 by means of their internal threads 20. After screwing the latching sleeves 10 with the threaded bolt 30, the latching sleeves 10 are perpendicular from the second fitting element 28.

The first fitting element 26 comprises, in addition to the door lever bearing 32, two locking bolts 34, which likewise have a thread and are welded to the first fitting element 26 in such a way that they protrude perpendicularly therefrom.

For mounting on a door leaf, for example, the snap-on sleeves 10 are screwed onto the threaded bolts 30, as described above. Subsequently, the second fitting element 28 is introduced with the screwed-on snap-in sleeves in prepared holes of the door leaf from one side of the door panel.

The first fitting element 26 is then inserted from an opposite side into the prepared holes of the door leaf, wherein the Stop bolt 34 meet inside the door leaf on the snap sleeves 10. If the latching pins 34 are pressed against the latching sleeves 10 by pressure on the fitting elements 26, 28, the partial projections 19 are forced outwards and allow the latching pins 34 to be inserted into the latching sleeves 10. The partial projections 19 repeatedly snap in axially during insertion successive depressions of the thread of the locking bolt 34 a.

If the fitting elements 26 and 28 are arranged correctly on the door leaf, they are held in this position by the engagement of the latching projections 18 in depressions of the thread of the latching bolts 34. Due to the larger angle of the slope of the first bore 14 of the locking projection 18 is a holding force, which holds the fitting elements 26 and 28 in position, greater than the force necessary for mounting.

Fig. 4 shows two embodiments of the fitting assembly according to the invention in an assembled state, which is present for example after mounting on a (not shown) door leaf.

Two fitting arrangements can be seen, the first and second fitting elements 26, 28 being fixed to one another in each case by the engagement of the latching bolts 34 in the latching sleeves 10.

Both embodiments are designed as rosettes. The embodiment shown in the upper area comprises door lever elements in the form of two door handles 36 and a square 38. The embodiment shown below comprises two recesses 40 for a lock cylinder.
