Description

The present invention relates to a faceplate fitting accordingly the preamble of claim 1.

In general, faceplate fittings consist of a faceplate and one including longitudinally displaceable drive rod, which is used to actuate the Serve locking means of the door or window wing. The usual way are such cuff rail fittings in a door or Window frame incorporated groove. To attach the Forend rail fittings in the groove have been different in the past Solutions have been proposed.

With DE 197 30 600, the applicant has a faceplate fitting proposed, in which the faceplate is attached to a holder, the is W-shaped or V-shaped in cross-section, the holder being free Has leg and made of an elastically deformable material Plastic or metal is made. When introducing the Forend rail fitting in the door or window frame for this The groove provided forms a faceplate fitting up to final fastening by means of fastening elements fixing frictional engagement which is also effective for grooves with bars.

The well-known faceplate fitting only supports installation. In order to fix the faceplate fitting in a functionally reliable manner, it is necessary. other fasteners. The faceplate fitting is suitable for  automatic or semi-automatic assembly, in which in a first Step, the faceplate fittings are inserted and fixed, while the final attachment takes place in a second step. The frictional engagement caused by the holder is already when the To overcome the faceplate fitting. Provided to insert the Fittings, special devices and / or machines are used, is this additional force to be overcome for the entire process and the Interpretation of the device or the machine negative.

Another faceplate fitting is from DE 31 01 393 C2 become known in which the faceplate over an intermediate Spacer and a detachable connecting element with a holder connected is. The holder is U-shaped in cross section. The Side legs of the holder have resilient tongues, which in the Installation position in the groove in the door or window frame reach behind arranged webs.

This faceplate fitting is also relatively higher To operate tools. Furthermore, the individual components, that is U-shaped holder, the drive rod, the spacer, the faceplate and finally to handle the screw connections individually. About that is due to the given location in the drive rod arranged elongated holes a cumbersome pre-assembly of the U-shaped Holder. The positioning of the drive rods as well as that Inserting the spacers is complex. Accordingly awkward is the putting on of the faceplate and its final fastening through the connecting element.

Another holder for fastening cuff rails is from DE 297 16 501 in the form of a bracket. The part that is punched and bent manufactured bracket has an essentially U-shaped cross section, whereby resilient fastening tabs protrude on the two legs.

At the end of the legs, clamping tongues are arranged, which the  Grip the faceplate under pretension. The are supported during assembly resilient fastening tabs under tension on the walls of the Groove and dig into the soft plastic material of the Casement.

This fastening of the faceplate is done by a single component, however, the faceplate can be manipulated by external manipulation of the punching and bending Partly in the groove for safety reasons only in harmless places Application come. The assembly is also cumbersome because the holder from Must be pre-assembled by hand over the faceplate. In particular, can a subsequent correction - be it due to an assembly error or else also a repair - can no longer be made, since the Hook clamping tongues on the flanks of the groove and in the event of removal the frame material badly damaged.

Another device for fastening a faceplate in a groove in Window or door frame made of plastic or wood is from DE 30 41 500 known. One that can be positively coupled to the faceplate Holding element overlaps the faceplate on both sides of the groove. The holding element is designed as an expansion body, the anchoring arms in the Notches of the faceplate provided on the narrow sides of the faceplate intervene in the longitudinal direction. The notches point Boundary surfaces that diverge in the longitudinal direction of the faceplate. When moving the expansion body in the longitudinal direction cause diverging boundary surfaces spread the anchoring arms. On the side, the anchoring arms have drive-in tips, which are on the sides in the Penetrate the material of the window or door leaf and the faceplate on the Anchored point in the wing as soon as the holding element in Longitudinal direction of the faceplate within the notches in the direction of diverging boundary surfaces is shifted.

A disadvantage of the examples is that the force of the Driving tips and clamping tongues, especially for plastic frames  flow effects can go unnoticed. With wooden frames they lead Driving tips and clamping tongues for indentations in the wood, in the unnoticed Moisture penetrates and can greatly reduce the strength of the wood. As experience shows, both episodes occur without being outside are initially visible. Such notches also result especially with wood easily to sustainably impair the strength Cracks. The secure fixation of the faceplate is essential Prerequisite to the drive rods arranged below before manipulation to protect.

The object of the present invention is therefore a fitting part to propose, on the one hand, not the disadvantages mentioned above occur and on the other hand a high degree of automation during assembly is accessible for all frame types and materials.

This object is achieved according to the invention in that the U = shaped Guide element at least one integrally molded clamping function means is assigned, which can be exerted by externally applied force into one Leg of the U-shaped guide element slightly spreading functional position can be transferred safely in order to form a faceplate fitting the holding force holding the groove.

This will also cause excessive jamming when inserting the Faceplate fitting avoided, as is the case with known Clamping devices is the case based on an elastic deformation of the Guide element based when inserting.

The holding force is achieved according to the invention by the slightly spreading Functional position of the legs secure the faceplate fitting stuck magnitude. This makes it amazingly simple both a permanently safe material and a material surrounding the groove of the door or window frame gentle semi-positive connection causes. At the same time, the assembly effort is reduced to a minimum, because  after inserting the fitting part into the groove only the integral Molded-on clamping function means using simple tools from outside applied force in his legs of the U-shaped Guide element easily spreading functional position is transferable.

According to a further feature of the invention, this is preferably Clamping function means at the district end of one of the legs of the U shaped guide element integrally formed, obliquely in the space between the U- shaped guide element facing barrier.

This eliminates the need when attaching such faceplate fittings the long manufacturing times previously required on the casement, since that Screwing in or adjusting fastening screws without replacement or at least temporarily not applicable. This has taken a lot of time so far so that even the production in automatic systems was uneconomical. In addition, the manufacture was used in such fittings Driving rods very expensive, because a lot of slots in the Punching the connecting rod was necessary to secure the screw To allow impact in the hardware groove. This in turn caused the subsequent processing of the drive rods on straightening devices, as a Torsion of the connecting rods is not permitted. Accordingly, one had to Large number of countersinks (ring countersinks) on the relevant Connection points are introduced into the frame material. This resulted all in all to an unmanageable number of different Tools and a correspondingly high reserve in extensive To store.

If, on the other hand, only provisional fixation of the fitting is provided, then can be a reliable backup by this measure in a simple manner of the faceplate fitting can be reached until the fasteners, z. B. in the form of screws, are finally attached.

Becomes a predetermined breaking point between the distal end and the barrier  provided that when the locking web is transferred into the legs spreading functional position is breakable, the guide element or the faceplate fitting can be removed if necessary.

This allows the fitting to be removed if necessary Remove the fastening screws again. Re-assembly may with fastening screws or new guide elements.

According to a further feature of the invention, the predetermined breaking point is advantageous assigned an abutment that acts as a pivot during assembly. This Abutment serves on the one hand when transferring the clamping function means into the the legs spread functional position and on the other hand to secure the Locking function, i.e. when the clamping function means is transferred to the functional position.

According to a further feature of the invention, the A predetermined rounding point distal the end of the barrier web intended. This allows the hook to slide open Barrier web, e.g. B. on the opposite of the predetermined breaking point Limb surface. This is also a highly automated production possible because disturbances when transferring the clamping function means in the Functional situation are effectively prevented.

Alternatively, according to a further feature of the invention Clamping function means as integral to at least one of the legs of the U-shaped guide element integrally formed spreading stamp formed the at the district end of the leg or the leg in a space between the legs of the guide element is arranged.

The expansion stamp also has an in the installed state on the Groove-supporting level butt plate, and on the butt plate opposite side at least one expanding saddle. It is after one  Training between spreader saddle and preferably the distal end of the leg a predetermined breaking point is provided, which when transferring the Guide element in which the leg spreading functional position is breakable.

According to a further feature according to the invention, the U- shaped guide element is provided at least one guide pin, the immersed in a guide hole arranged in the expansion punch. Further the faceplate has at least one elongated hole which the Assigned guide pin penetrates. This allows the drive rod additional guidance can be given.

On the leg is according to another advantageous feature of the invention at least one oblique pressure surface in the area of the predetermined breaking point arranged. This ensures a controlled and defined sliding of the Spreading saddle causes during assembly.

According to a further feature of the invention, the faceplate forms with the U-shaped guide element is a firmly connected component.

The individual components are preferably made of frost-free steel, as a result the corrosion problem is relieved in the long term.

According to a further feature of the invention point in both Embodiments of the legs in the non-functional position Condition light a facing towards each other, so that safe and precise insertion of the invention Cuff rail fitting is guaranteed in the groove.

According to the invention, the predetermined breaking point has a further feature at least one arranged inside the U-shaped guide element Notch on, whereby the predetermined breaking point can be defined locally.

According to the invention, the one exerted by the clamping function means acts  The action of force to form a holding force preferably in the area of the groove base on the window or door frame. This will Flow tendencies and deformation of the wing or frame prevented.

According to a further feature of the invention, this has an integral molded-on clamping function means return means with which the Clamping means from its the legs of the U-shaped Guide element slightly spreading functional position in the starting position is at least temporarily retrievable. This supports the detachment of the Fitting in the groove holding clamping force.

The invention is based on two in the drawing more or less schematically illustrated embodiments.

Show it:

Fig. 1 shows a first embodiment of a Stulpschienenbeschlages according to the invention in cross-section before insertion in a frame groove with intact predetermined breaking point,

Fig. 2 shows the Face plate fitting according to FIG. 1, after insertion into the frame with dissolved breaking point in a fixed position

Fig. 3 shows a second embodiment of a faceplate fitting according to the invention in cross section with an intact predetermined breaking point and

Fig. 4 shows the predetermined breaking point of the faceplate fitting according to FIG. 3 after insertion into the frame groove with the released breaking point in a fixed position in an enlarged view.

In Fig. 1, the faceplate fitting 10 is shown with inserted drive rod 11 before insertion into a groove 12 of a window or door frame 13 made of plastic or metal. The faceplate fitting 10 comprises an essentially U-shaped guide element 14 which is fixedly connected to a faceplate 15 , the faceplate 15 projecting beyond the U-shaped guide element 14 . The U-shaped guide element 14 has legs 16 , 17 on both sides. An integrally molded clamping function means 30 in the form of a locking web 19 is assigned to one leg 16 at its distal end 42 via a predetermined breaking point 20 . The predetermined breaking point 20 between the leg 16 and the locking web 19 is embodied by a notch 21 which weakens the cross section. Above the notch 21 , an abutment 22 is arranged in the form of a locking bead 23 . A start rounding 25 is provided at the distal end 24 of the barrier web 19 . The faceplate 15 , the middle part of the U-shaped guide element 14 and the drive rod 11 have mounting openings 26 through which an assembly tool 27 can be inserted, which is indicated by dashed lines in FIG. 1.

In FIG. 2, is shown in its Face plate fitting, inserted in the groove 12 of layer 10. The faceplate 15 closes at its top 28 essentially flush with the surface of the door or window frame 13 . The legs of the U-shaped guide element 14 are embedded except for the groove base 29 of the groove 12 . The assembly tool 27 is initially placed on the locking web 19 in the direction of the arrow through the assembly openings 26 . By applying an external force F to the assembly tools 27 , the locking web 19 is broken off at the predetermined breaking point 20 and transferred into a functional position 30 , the legs 16 , 17 of the U-shaped guide element 14 , the locking web 19 being on the one hand at the distal end 24 in the region of the predetermined breaking point 20 and the other hand to an electrode disposed on the distal end 24 of the barrier web 19 Anlaufverrundung 25 verhakungsfrei first slides onto the facing lateral side surface 34 and is supported thereon in the course of Abgesenkens of the mounting tool. The abutment 22 embodied by the securing bead 23 on the leg surface 33 is clearly recognizable, which ensures that, under the pressure of the assembly tools 27 , a pivot 35 , that is to say a swivel bearing, is formed in the area of the predetermined breaking point 20 and the locking web 19 reliably assumes its functional position 30 reached. The resulting holding force preferably acts in the region of the groove base 29 on the side cheeks 47 , 48 of the groove.

As can also be seen from FIG. 2, a plurality of drive rods 11 can also be arranged one above the other. Furthermore, the locking web 19 has a return opening 41 , into which a return means 45 indicated in dash-dot line can be inserted and the locking web 19 can be released from its functional position 30 .

It can also be provided that the legs 16 , 17 in the unassembled position according to FIG. 1 - in contrast to the illustration made there - taper so that the guide element 14 is given a substantially trapezoidal cross section by this setting.

As a result, the opening cross section in the region of the free ends of the legs 16 , 17 is narrower than the U-web associated with the faceplate 15 and also forms an insertion aid for the faceplate fitting 10 .

It can be clearly seen that the length of the locking web 19 - between the legs 16 , 17 - is larger than the web opposite it, which is assigned to the faceplate.

An alternative embodiment is shown in FIG. 3. The faceplate 15 and the U-shaped guide element 14 , as stated above, form a component that is firmly connected to one another. Between the legs 16, 17 is the operating means 30 at the distal end 42, 43 of the legs 16, 11 of an embodied in the space between the legs of the guide element 30 in the form of an integrally formed Spreizstempels 50th This has a flat butt plate 51 which is supported on the groove base 24 in the installed state and a spreading saddle 52 on the side opposite the butt plate. A notch 21 is arranged between the upper region of the expanding saddle 52 and the distal ends 42 , 43 of the legs 16 , 17 . Towards the butt plate 51 , the expansion saddle 52 has oblique pressure surfaces 53 , to which a stop collar 54 is finally assigned, which is dimensioned such that the expansion of the legs 16 , 17 does not exceed a predetermined dimension. In this way, on the one hand, a controlled sliding of the expanding saddle 52 during assembly and, on the other hand, an implicit limitation of the holding force holding the faceplate fitting 10 in the groove 12 is generated, as is shown in detail in FIG. 4.

In the U-shaped guide member 14, a guide pin 55 is centrally arranged, which dips into a disposed in the Spreizstempel 50, centrally disposed guide bore 56th Elongated holes 57 are made in the faceplate 15 , through which the guide pin 53 passes. The length of the guide pin 53 and the dimensioning of the stop collar 54 are to be coordinated in length in such a way that the holding force which holds the faceplate fitting 10 securely in the groove 12 is not impaired in the functional position 30 which slightly spreads the legs 16 , 17 .

In order to release the holding force holding the faceplate fitting 10 in the groove 12 , a pressure force which drives them apart is to be applied from the outside between the expansion ram 50 and the faceplate 15 or the parts introduced into the U-shaped guide element, as a result of which the faceplate fitting 10 without damaging the groove is removable. The necessary engagement space can be provided in that the guide pin 55 is pulled with a puller shown in dot-dash line and a, the pressing force exerting expanding tool described solved is introduced into the released opening.

Both embodiments have in common that the legs 16 , 17 in the state not in the functional position 30 have slight offsetting towards one another. The decisive factor is that the dimension of the clear width of the distal ends 42 , 43 of the legs 16 , 17 is not wider on the outside than the U-shaped guide element 14 .

Furthermore, in both embodiments, the spreading force effective in the functional position 30 in the groove 12 can be predetermined by geometric means, on the one hand by the length of the legs 16 , 17 and in the other case by the stop collar 54 .

Finally, it should be pointed out that the predetermined breaking point 20 shown in the exemplary embodiments is not essential for the function of the guide element 14 .

However, the provision of the predetermined breaking point allows the faceplate fitting 10 and / or the guide element 14 to be easily removed from the groove 12 .

It should also be mentioned again that the fastening is carried out in addition to or instead of fastening with fastening elements such as screws. When mounting by means of a device which attaches the faceplate fitting parts from a magazine to the wing, can be by the mounting bracket of the faceplate fitting part, for. B. the assembly tool 27 are provided. Inserting and at least fixing is done by the assembly tool, which the faceplate fitting part z. B. from the magazine or the like to the wing.
