Abstract

Two fixture holes (8,9) are positioned on each side of a tubular neck (19). A metal reinforcement plate (21) has a hole (22) esp. in the centre of it and through which goes the neck of the round anchor plate. At least one radially protruding catch (24) on the neck grips over the edge of the hole in the reinforcement plate, in a locking position. The catch is in the form of a wedge-shaped lug protruding beyond the outer casing of the neck.

Description

The invention relates to a rosette for rotating Storage of a handle for actuating at least one Locking mechanism of a window or a door, with two arranged on both sides of a tubular neck Mounting holes and a non-rotatable metal reinforcement plate, its central one in particular Hole is penetrated by the neck of the rosette, the reinforcement plate is held in the position of use on the neck of the rosette.

Rosettes of this type are usually made of plastic manufactured and they get their increased rigidity through the use of a reinforcement plate. The word "tin" is to be understood here in the broadest sense because this component does not necessarily have to be perfectly flat, as is the case with a sheet is the case. On the other hand, it will be in everyone Usually made of sheet steel, the material seen high strength. This can be done, for example Expressions u. Like. be increased.

When making a rosette, reinforcement plate and at least one actuating handle rotatably mounted thereon the window or door fitting is in accordance with, for example, DE-A-2 250 558 first the rosette with the reinforcement plate into one Subunit summarized. Then there is the further one Assembly. The mounted fitting is then on vertical bar on the closing side of the window frame or door chipped, usually with the help of two screws screwed on.

If with another fitting, the rosette subunit and reinforcement plate before further assembly to one subsequent manufacturing station must be transported, so the problem often arises that the Reinforcement plate detaches from the rosette and the subunit delivered to the next production station in two parts becomes. As is known, the transport takes place in transport boxes u. the like

To avoid this undesired detachment of the reinforcement plate from Avoiding the rosette can be based on DE-A-2 250 558 the neck at the transition to Rosette body to be slightly enlarged in diameter. On this increase in diameter becomes the central one in particular Pressed hole of the reinforcement plate, which then both Parts are held together by friction.

The disadvantage is a difficult assembly of the Reinforcement plate on the neck of the rosette. With less favorable Tolerance, it may even be impossible to be safe To achieve a connection between the rosette neck and the reinforcement plate, rather, the reinforcement plate can be released again spring back. The reinforcement plate can spring back also occur later with the assembled unit. If the latter still has a lid to cover the Has fixing screws of the rosette, this can lead to further difficulties if, for example Disassembly of the unit is necessary.

Pressing the reinforcement plate onto the thickened neck can also lead to the fact that the The rosette neck is slightly elastic and this leads then to a stiffness of the coaxially recorded Operating handle.

An actuating handle is known from EP-A-0 460 297 become, in which a handle or its neck Cover plate, a reinforcement plate underneath and penetrates a rosette to be mounted on the frame. If those Fitting unit is fully assembled, so it can Do not detach the reinforcement plate from the rosette because it is from a bolt sleeve of a special coupling is held down. The formation of a subunit Rosette and reinforcement plate and in particular a Transport of this subunit is not provided there.

It is therefore the task of a rosette of type mentioned so that the described disadvantages do not occur and a safe, connection of rosette that no longer detaches itself and reinforcement plate is still possible.

This task is based on the preamble of claim 1 characteristic features solved.

By locking the reinforcement plate to the neck of the Rosette instead of the usual pressing, on the one hand you can achieve a secure connection between the two Components, on the other hand, a loose hold on the Reinforcement plate on the neck of the rosette, so that radial Neck constrictions are excluded and the Subunit no longer for in-house transport can fall apart.

Accordingly, there is at least one radial on the neck of the rosette protruding locking element attached, in particular molded in one piece, which in the locked position of the Reinforcing plate with the edge of the hole from above spreads. By appropriate shaping one can achieve that the locking takes place resiliently and nevertheless pushing back against the assembly direction cannot take place under the usual loads. What As far as the design is concerned, there is one thing above all Run-up slope or the like thought. It is not preferred only a radially protruding locking element is provided, but preferably at least two, around 180 ° on the neck offset locking elements used. In itself is also one conceivably kinematically reverse solution, which consists in that the central bore of the reinforcement plate at least a radially inwardly projecting nose or the like. has at assembly along the resilient neck of the Rosette slides and when an undercut is reached or circumferential groove jumps into the latter.

A development of the invention provides that Locking element as a wedge-shaped, over the outer jacket of the Neck protruding nose is formed. Such a nose automatically forms the above-mentioned slope, over which the Reinforcement plate is pushed on during assembly. In the In the final assembly position, it engages under this nose comparatively little axial play. The dimensioning the nose is in relation to the hole of the reinforcement plate to choose so that even with an unfavorable tolerance Reinforcement plate is always held securely and when the Tolerances come together unfavorably in another sense can still turn the sheet by the neck.

To improve the elastic behavior and thus also the assembly of the reinforcement plate, will be further Embodiment of the invention proposed that the Wall thickness of the neck in the area of the locking element on the Inner wall of the neck is reduced. The Wall thickness reduction can be, for example, about 50% compared to the normal constant wall thickness of the neck. Man In this way it improves the problem-free radial compression the nose when pushing the reinforcement plate onto the Neck.

A particularly preferred embodiment of the invention provides that the reduction in wall thickness over a Circumferential angle extends approximately three times Corresponds to the circumferential angle of the latching element. This improves the elastic behavior in this area the assembly of the reinforcement plate. In the longitudinal direction of the Seen throat, the reduction in wall thickness can over the area of the nose towards the free edge of the Neck a little further than the nose.

It is also seen in another direction by an inner one Wall thickness reduction achievable in very recess advantageously up to the inner rim of the mouth Neck drilling continued. This is particularly important very much on the production or molding when spraying expedient.

The breakthrough mentioned enables the assembly of the Subunit an even better radial compression in the Reduced thickness wall area with the locking element.

Essential elements of the handle fitting of FIGS. 1 and 2 are the handle 1 with the non-rotatably connected square mandrel 2 as well as a rosette 3 and a cover 4. It is essential that the handle 1 is rotatable about the geometric axis 5 and axially immovable is mounted on the rosette 3. One in the drawing shown, but not below explained in more detail, device can possibly turn positions define, for example, starting from the position shown in Figure 1 one or two consecutive 45 ° - or 90 ° turning positions.

About the square mandrel 2 is on the window or Door fitting in the sense of locking and unlocking if necessary also to carry out further adjustment movements Hardware acted.

The rosette 3 has two cone-like in the embodiment Approaches 6 and 7, which in corresponding boreholes on closing-side, preferably vertical spar of a window or intervene in the door leaf. This way you get a good one Fixation and alignment of the rosette 3 and thus the entire handle fitting opposite the sash. The cone-like approaches 6 and 7 each have a continuous Bore 8 and 9 for a not shown Fastening screw. So that their head is not visible, is located above the rosette 3 as seen from the frame the lid 4. Its size corresponds to that of the rosette, however, it is lower. It consists of a very thin-walled material, preferably plastic. As a result, it is in the direction of arrows 10 and 11 resiliently bendable. It consists of at least one flat top wall 12 and a circumferential, the same all around high, in the embodiment rectangular cranked Edge 13. In addition, a centric, opposite edge 13 protruding nozzle 14 available, in particular molded his. According to FIG. 2, it engages in a corresponding receptacle of the handle 1.

If you have the cover 4 on its narrow sides 15 and 16 seizes and bends up in the direction of arrows 10 and 11, so you can then turn it by 90 °, for example. He will be there over a circumferential, rectangular in the embodiment Rib 17 of the rosette 3 pivoted away (Figure 4).

The circumferential recess 18 of the rosette 3 is of the type an approximately rectangular groove, which so is dimensioned in that the peripheral edge 13 of the Lid 4 finds space and the lid 4 according to Figure 2 runs flush with the rosette 3 all around.

According to FIG. 4, the rosette 3 has a tubular neck 19 equipped, possibly with the connector 14 of the cover 4 little play is included. In this case, according to Figure 2 of the nozzle 14 of the lid 4 with sufficient play into the recess 20 at the front end of the handle 1 on. A reinforcement plate is captive on the rosette 3 21 held. Both form the aforementioned Subunit, on which the operating handle 1 and if necessary, additional fitting elements can be installed.

The reinforcement plate 21 has a central bore 22 (Figure 4), the diameter taking into account a usual sliding fit the outer diameter of the neck 19th corresponds to rosette 3. That in the sense of arrow 23 of FIG. 4 latching-out latching of the reinforcement plate 21 on the neck 19 of the rosette 3 can be reached with the help of two Locking elements 24. They are attached to the outside of the neck 19, in particular molded in one piece and lie one against the other across from. They are preferably also pointed Angle to the transverse central axis 25 (Figure 3). From Figures 3 and 4 it follows that when fully assembled Reinforcing plate 21, the locking elements 24 the edge of the Overlap bore 22. That way it will Reinforcement plate 21 in the formed by the ribs 17 Recording 26 of the rosette 3 against lifting and due to the Shaping also held securely because the outer surface of the Reinforcement plate 21 approximately flush with the free edge of the Rib 17 runs. As can be seen particularly clearly from FIG. 5 results, have the locking elements 24 when Embodiment the shape of a radial over the Outer surface 27 of the tubular neck 19 protruding nose approximately triangular shape and constant thickness, whereby in the sense of arrow 28, that is, the direction of postponement Reinforcement plate 21 seen, a run-up slope formed becomes. When pushing on the reinforcement plate 21 they give way Locking elements 24 in the direction of arrow 29 resilient radially backwards.

To improve the resilient evasive movement in Arrow direction 29 is the wall thickness of the neck 19 in the area each locking element 24 reduced by approximately 50% (FIG. 5). This reduction in wall thickness is achieved by attachment a recess 31 on the inside wall 30 of the tubular neck 19. This recess 31 extends 6 over an angular range that is about three times as high is as large as the angular range over which that Latching element 24 extends. According to Figure 5 that is sufficient Indentation slightly higher up than the locking element 24. Furthermore, it is down to the mouth level 33 the bore 32 of the neck 19 performed.

At the transition from the neck 19 to the rosette body 34 is on the neck 19 in the area of each latching element 24 a radial one Breakthrough 35 attached (Figures 4 and 5). This will the elastic behavior of the locking elements 24 further improved. It extends in the circumferential direction of the Wall thickness reduction or depression 31 over a Angle that corresponds to that of the recess 31. In Viewed in the axial direction, each opening 35 extends approximately from the lower edge of the associated latching element 24 to Surface 36 of the rosette body 34 facing away from the spar. Furthermore, the rosette body 34 is in alignment with everyone Locking element 24 and in the center of the opening 35 or the Indentation 31 has a groove 37 directed radially outwards available.

Open into the central bore 22 of the reinforcement plate 21 two extending in the radial direction Center hole enlargements 38 and 39 which shape have open slits. The slot width corresponds thereby about the diameter of the extension located screw through hole 40 or 41 of the Reinforcing plate 21. Each of the two through holes 40 and 41 is located as shown in FIG a funnel-shaped protuberance 42 that formally into a adapted conical recess 43 of the rosette body 34 intervenes.

The slot width of the center hole enlargements 38 and 39 corresponds at least to the diameter of a locking bolt 44 of a lock 45 inserted in the rotary handle 1.
