EP2146029B1 - Door frame profile with a striker plate - Google Patents

Description

The invention relates to a door frame profile with a locking strip attached to the door frame profile for a door lock with zurückdrückbarer latch, wherein the door frame profile has a front end web and a recess, wherein the locking strip is attached to the door frame profile in the region of the recess and in the closing direction behind the end web of the door frame profile , wherein the locking strip has an opening which is arranged in the assembled state in the region of the recess of the door frame profile, wherein in the opening a locking piece is arranged with a locking lug for the latch, wherein the locking piece is formed in several parts and at least one lower part and a relation to the Lower part has a displaceable upper part with the locking nose. - Closing direction means in the invention, the direction in which moves the latch of the door lock on the corresponding door frame profile and consequently on the mounted on the door frame profile closing strip. The door frame profile may be made of metal, for example aluminum and / or steel, or also of plastic. The opening in the closing strip, in which the locking piece is used, is preferably designed as an edge-open aperture, so that such a locking bar can be optionally equipped with a "conventional" locking piece or locking counterpart or with an electric door opener, wherein the electric Door opener has or contains a locking piece. In both cases, the locking piece is usually an adjustable locking piece with which assembly tolerances can be compensated. Always the case of the door lock engages in the course of its closing movement, the locking piece or the locking lug of the locking piece and thus keeps the door closed.

Such a door frame profile or such a closing strip is for example from the DE 102 15 014 A1 known. The closing strip is equipped with an electric door opener, with an opener trap and with a locking nose. In the passage opening of the closing strip at least one with a predetermined inclination of the one opening edge out angled sliding bar for the lock latch is arranged, which passes through a Fallenausnehmung in the normally closed case. At the end of the angled sliding bridge is followed by a substantially parallel to the strip front side extending web part. Optionally, the bridge part can be adjoined by a web extension led up to the other opening edge, wherein the slide web, the web part and the web extension form a structural unit with the closing strip or with the strip front part.

Furthermore, we know a closing strip with a door opener for a door lock, which is also provided with such a slide bar. The sliding bar is in this embodiment part of a flat-building trap chute, which has a central slide bar and on both sides of the slide bar openings for the locking lug of the NC trap. The trap chute further has on the front opening side a channel-like overlap for a web profile on the door frame profile (cf. DE 10 2004 012 112 B3 ).

From the DE 66 08 192 one knows a door frame profile with a closing strip mounted on it. The door frame profile also has a recess and the closing strip also has an opening, wherein the opening of the closing strip is arranged in the assembled state over the opening of the door frame profile. There is also provided a locking piece, which is designed there as a Öffnerfalle.

The GB 2 383 077 describes a closing strip on which a multi-part locking piece with lower part and upper part is mounted.

The well-known door frame profiles or closing strips, which can be optionally equipped with a simple adjustable locking counterpart or an electric door opener, have basically proven in practice, but they are capable of further development. Disturbing may be the high noise in the course of closing the door, as the latch - possibly depending on the installation situation of the locking piece - twice strikes, namely first against the end web and then against the leading edge of the locking piece. This can lead to damage to the frame profile, especially in the area of the end bar.

Incidentally, there is a general danger that these double "impact noises" cause the slightest movement already after the first impact sound creates the impression that the door is already closed. In particular, there is the danger that the lock latch between the front closing edge and the locking counterpart engages, so that the door is just not closed in this case. In particular, when closing strips are used without E-opener, they are equipped with an adjustable locking piece, the adjustment makes it possible to vary the contact pressure of the rubber seal. Consequently, installation tolerances can also be compensated with the adjustable locking piece. Such a counterpart counterpart consists of upper and lower part, which are screwed together. If one loosens the screws of the locking counterpart to adjust the contact pressure, there is always the danger that the lower part falls into the frame profile. With a built-in door then there is no possibility to get to this lost base. If, moreover, the maximum adjustability is utilized in the case of such adjustable locking counterparts, the known embodiments have the problem that a gap arises between the terminating web and the locking piece, which results a look into the inside of the profile allowed. This is undesirable from an aesthetic point of view.

The same applies if due to cramped space in the frame profile no perfect pivotal movement of the locking counterpart of an electric door opener is possible and for this reason the end web of the door frame is milled. Even then, an ugly opening is created, which allows a view into the interior of the frame profile. Incidentally, this is also unsatisfactory from a technical point of view, since, for example, drafts can pass through the door. Furthermore, it must be taken into account that the door frame profiles are usually already supplied to the door manufacturer as profile powder-coated profile bars. Subsequent milling of the profile creates a bare, silvery surface, which also disturbs for aesthetic reasons.

The invention has for its object to provide a door frame profile with a locking strip for a door lock with rückdrückbarer latch of the type described above, wherein the locking bar is universally applicable in a simple and inexpensive construction and meets all technical and aesthetic requirements.

To solve this problem, the invention teaches in a door frame profile with closing strip for a door lock with zurückdrückbarer latch of the type described above, that the lower part of the locking piece (fitting) engages in a web section of the end web, said web section connects to the recess of the door frame profile, so in the course of the closing movement, the latch does not start against the front end bar itself. The invention is initially based on the knowledge that the door frame or the door frame profiles in any case suitably, For example, be processed with a CNS milling machine, since at least one recess is provided in the region of the closing strip to be mounted, which corresponds to an opening in the closing strip and in which recess engages, for example, an electric door opener. Such a recess is introduced into the door frame profile already in the course of production of the door frame profile, without having to determine whether this door frame profile is later equipped with a closing strip with E-opener or with a conventional adjustable locking counterpart. For these reasons, it is first of all in manufacturing terms, no additional effort to bring in the final web of the door frame profile a web section, for example, to mill. However, the aesthetic disadvantages described in the introduction are avoided in the context of the invention in that the locking piece of the locking strip according to the invention (precisely fitting) engages in the web section and consequently in the cutout of the end web. The released in the course of milling out shiny metallic surfaces are thus covered by the locking piece. Incidentally, the locking piece of the closing strip according to the invention does not already end behind the end web, but it extends into the region of the end web, namely into the region of the cutout of the end web, so that no double start-up noise when closing the door arise.

This applies first of all for a first embodiment of the invention, in which work is done without electric strike. The locking piece is in a known manner in several parts, for example, formed in two parts and has at least one lower part and a relative to the lower part displaceable upper part, wherein the upper part has the locking lug. According to the invention, the lower part now engages (with a precise fit) in the milled-off web cutout. For this purpose, it is advantageous if the lower part has a counter-locking tab projecting against the closing direction, which engages in the web section. In the assembled state, the lower part, for example, the fitting tab then flush with the front surface of the end web. This results in an aesthetically very satisfactory solution. In addition, double start-up noise - as already described - avoided. Furthermore, it may be expedient if the fitting tab is delimited laterally by projections which project in the manner of a nose and terminate flush with the surface of the terminating web. Thus, the locking piece fills with pass tab and the protrusions the milled out completely and accurately. The upper part is preferably adapted in shape to the shape of the lower part and in particular the shape of the fitting tab and projections, so that it can be properly placed on the lower part and still be moved relative to the lower part. According to a further proposal of the invention it is provided that the lower part has one or more, for example laterally projecting retaining wings, which overlap as an assembly aid, the recess of the door frame profile and rest on the door frame profile. These retaining wings prevent the lower part from falling into the recess of the door frame profile and consequently into the interior of the door frame profile during assembly, for example when the screw connections are loosened.

The lower part of the locking piece is therefore preferably mounted in a fixed predetermined position such that it fits precisely and flush with the Closing the end web of the door frame profile. The upper part can now be moved in the desired manner relative to the lower part, for example, to compensate for installation tolerances or to vary the contact pressure of the door or its rubber seal. For this purpose, the upper part in a conventional manner, the locking lug, which has the rear side, the locking edge for the latch. On the front side, the locking nose preferably has a bevelled starting edge for the lock latch. Thus, the case slides when hitting this beveled leading edge or closing edge friction and low noise and gets behind the locking lug of Sperrgegenstückes.

As already explained, the closing strip can be used universally not only with adjustable locking counterpart, but also with electric door opener. The locking piece is then formed in the context of this embodiment as (electric) door opener, which has a movable Öffnerfalle with the locking lug. Furthermore, the locking piece has a latch slide which is displaceable relative to the opener latch, this latching slide forming the front starting edge for the latch latch. According to the invention, this trap piece is now provided in the case of the slide that this trap slide (precisely fitting) engages in the step cutout and consequently in the cutout of the end bar. In the context of the invention, therefore, the end web of the door frame profile can be milled, without it being established at the time of manufacture, whether the multi-part locking piece already described or the electric door opener is mounted. Always the aesthetic and functional disadvantages described are avoided because the locking piece, and in the case of the electric door opener, the trap slide, engages accurately in the web section. The trap chute or its front-side leading edge preferably ends flush with the front surface of the terminating web. The leading edge of the trap slide can also be formed chamfered in this case. Furthermore, it may be appropriate if the Leading edge of the trap slide is lowered relative to the surface of the end bar. Consequently, the trap does not impact sharp-edged milled front tread edges, but slides upon hitting the lowered and beveled leading edge of the drop chute.

The trap slide can be designed in a manner known per se with an inclined sliding web extending from the front edge in the closing direction for the lock catch, as described, for example, in US Pat DE 102 15 014 A1 is described. On the slide bar, a parallel to the strip surface extending web part can connect, which in turn can be followed by a raised to the other opening edge web extension. Then it is particularly useful if the leading edge of the trap slide has a thickening, which preferably extends into the region of the inclined sliding web. Such a thickening or raising prevents the latch between the front closing edge and the locking counterpart engages.

Overall, the disadvantages described above, which may arise in the prior art in practice, are avoided in the invention in a cost effective manner, although or precisely because the end web is provided with a web cut, which may be formed for example as a cutout , Nevertheless, the front frame profile edge is protected. It can no longer become one when the trap hits Chipping off paint or powder coatings come. The front profile opening is also nicely covered. This is particularly advantageous for designer doors. The silvery shiny surfaces released by the milling of the end bar are perfectly concealed and do not disturb. The rubber seal is otherwise close to the frame and it is also a low-noise trap inlet ensured without the risk of double start-up noise. With identical profile milling, both closing strips with or without electric door opener can be used. The door profiles can be manufactured with a single CNC program. A double storage is not required. The adjustability of the locking piece remains guaranteed. The latch snaps securely behind the locking counterpart in every locking situation and keeps the door closed. Moreover, a particularly cost-effective solution is achieved.

In the figures, a closing strip 1 is shown for a not shown door lock with zurückdrückbarer latch. The closing strip 1 is or is attached to a door frame profile 2 (see. Fig. 1 ). Such a door frame profile is made as a hollow profile of, for example, metal. The door frame profile 2 has a front end web 3. Behind this front end bar 3, the closing strip 1 is mounted in the closing direction. The closing direction is in Fig. 1 indicated by the arrow S. Closing direction S means the direction in which moves the case (not shown) in the course of closing the door on the closing strip 1. The closing strip 1 has an opening 4, which is formed in the embodiment as an open front opening. A comparative analysis of the Fig. 1 and 2 makes clear that the door frame profile 2 in the region of the opening 4 of the closing strip 1 has a recess 5, which is designed as a cutout. As will be explained below, can now, taking into account the recess 5 of the door frame profile in the opening 4 of the closing strip 1 either an adjustable locking piece without electric door opener (see. Fig. 1 to 4 ) or a locking piece with electric door opener (see. Fig. 5 and 6 ) deploy. Always a locking piece 6 is mounted in the region of the opening 4 of the closing strip, which has a locking lug 7 for the latch. The invention now provides that the end web 3 of the door frame profile 2 in the region of the recess 5 has a web cutout 8 in the form of a cutout. In this web section 8 now engages the locking piece 6 a perfect fit.

This is intended to be exemplary of a first embodiment according to Fig. 1 to 4 be explained. In this embodiment without E-opener the locking piece 6 is formed in two parts. It consists of a lower part 9 and a relative to the lower part 9 displaceable upper part 10, wherein the upper part 10 the Locking nose 7 has. In this embodiment, the lower part 9 of the locking piece 6 now engages accurately in the milled web section 8 of the front end web 3. For this purpose, the lower part 9 has an opposite to the closing direction S projecting and consequently a projection-forming fitting tab 11 which engages in this web section 8. The fitting tab 11 or the fitting projection thereby terminates flush with the front surface 12 of the end web 3. The fitting tab 11 is bounded laterally by nose-like projections 13, which run orthogonal to the fitting tab and terminate flush with the surface 14 of the end web 3. Overall, it is clear that by the combination of on the one hand the web section 8 of the front end web 3 and on the other hand the (exact) adaptation of the locking piece 6 or in the embodiment of the lower part 9 of the locking piece with fitting tab 11, a construction is created in which neither damage the frame profile are to be feared, still disturbing milling surfaces are visible.

To simplify the assembly of the locking piece 6 with upper part 10 and lower part 9, 9 two laterally projecting retaining wings 15 are provided on the lower part. These overlap the recess 5 of the door frame profile 2, so that they rest on the door frame profile 2. This prevents that the lower part 9 may fall in the course of assembly in the recess 5 and thus in the interior of the door frame profile 2. For lower part 9 and upper part 10 are fastened together by means of screws 16 and on the closing strip 1. For this purpose, the lower part 9 threaded holes 17, while the upper part 10 is provided with corresponding oblong holes 18, so that with slightly loosened screws 16, a shift from lower part 9 to upper part 10 is possible. In order to ensure a reliable fixation of lower part 9 and upper part 10 relative to one another, the upper part 10 and the lower part 9 are in a conventional manner with locking elements and locking counter-elements provided on the one hand on the upper side on the lower part and on the other hand are arranged on the lower side on the upper part.

A comparative analysis of the Fig. 1 to 4 makes clear that a latch in the course of the closing movement does not start against the front end bar 3 itself, but that this front end bar 3 has a cutout 8 in this area, which is covered by the fitting tab 11 of the locking piece 6, wherein the latch against the trap Locking nose 7 starts and this finally engages behind. The locking lug 7 consequently has, on the one hand, the (rear) blocking edge 19 and the (front) starting edge 20. The front edge 20 is bevelled to minimize the noise.

The Fig. 5 and 6 show now that the closing strip with identical door frame profile and identical recess 5 and identical ridge portion 8 can also be used with an electric door opener. In this embodiment, the locking piece 6 is thus formed as an electric door opener, which has a movable Öffnerfalle 21, which in turn is provided with the locking lug 7. Furthermore, the locking piece 6 in this embodiment has a latch slide 22 which is displaceable relative to the opener catch 21. This trap slide in turn has the front edge 20 ', against which the latch starts in the course of the closing movement. This starting edge 20 'is also chamfered in the embodiment. Also in this embodiment, now the locking piece 6 fits accurately into the cutout 8 of the profile web 3 a. In this case, the trap slide 22 engages accurately in this web section 8. The trap slide 22 thus concludes with its front edge 20 'flush with the front surface 12 of the end bar 3 from. In this case, the leading edge 20 'of the trap chute is not only bevelled with respect to the end web, but also lowered relative to the surface 14 of the end web 3.

Incidentally, it can be seen in the figures that the trap slide 22 has, in a manner known per se, an inclined slide web 23a extending from the front edge in the closing direction S for the lock latch, which is adjoined by a web part 23b extending essentially parallel to the strip surface which in turn is followed by a raised to the other opening edge web extension 23c. These web portions 23a, 23b, 23c are an integral part of the trap slide 22, that is, the trap slide with these webs is integrally formed. On both sides of the sliding webs 23a, 23b, 23c openings are arranged in the trap slide, through which the locking lug 7 of the NC latch 21 engages.

Incidentally, it can be seen in the figures that the front starting edge 20 'of the trap slide has a thickening or elevation 24, which extends from the front edge into the region of the sliding web 23a. With the help of this thickening or increase 24 is avoided that the trap between the trap slide 22 and the locking lug 7 can intervene and the impression arises as if the trap is already in the lock.
