Description

The invention relates to a closing strip assembly for a door lock, according to the preamble of claim 1 and in particular a closing strip assembly with a fastened to a door frame closing strip with a passage opening or a case passage for a zurückdrückbare latch of a door lock arranged on a door, wherein in the region of the passage opening Fallenrast is arranged, which is engaged behind by the lock latch in the closed position and with one of the latch catch in the closing direction upstream sliding surface on or on which the latch slide slides in the course of the closing movement. - The closing strip is regularly made of metal and is also referred to as a striking plate or closing part. It may be a cross-sectionally U-shaped or L-shaped closing strip or else a flat profile. The passage opening can in principle be designed as an opening which is closed on all sides, wherein the latching catch can then also be formed by a corresponding area of the striking plate. However, in the passage opening a catch member forming a catch receptacle with latching edge or latching lug is regularly used as catch latch. In this case, the passage opening may also be formed as a recess open on one side. The closing piece can be designed as a quasi-rigid closing piece with a rigid locking edge. However, it can also be arranged a pivotable and lockable locking edge on the closing piece. Finally, the invention also includes such closing pieces, which are designed as electric door openers with electrically actuated locking edge or locking lug. Door frame means in the context of the invention, in particular those of frame profiles, which are, for example, metal hollow sections, z. B. aluminum, can act.

In practice, there is the problem that the recoilable metal latch in the course of closing initially strikes against the frame leading edge, then slides along the inside of the door frame and then strikes again against the closing edge leading edge. This is associated with a significant noise that is perceived to a considerable extent as disturbing. This applies in particular to outward-opening doors, in which the strike plate has a clear distance from the front edge of the frame. In this context, it is known in the case of outward-opening doors from practice to form the closing strips as so-called flap-closing plates with a molded sheet-metal tab which serves as a sliding surface for the latch. The problem in this context, first of all, that for inward opening doors on the one hand and outward opening doors on the other hand, two different closing strips must be made. In addition, the considerable frictional noise and, in particular, the noise development in the course of striking the latch twice on the front edge of the frame and the closing edge leading edge are still disturbing. Finally, it is disadvantageous that the door frame and in particular the front profile edge or frame front edge is subject to considerable wear due to the case friction, wherein there is the danger that an applied lacquer layer will flake off, especially in the case of high-quality powder-coated doors. The invention aims to remedy this situation.

From the DE 87 02 113 U1 One knows a conventional strike plate for door locks with a passage opening for a latch, wherein a side edge of this passage opening cooperating with the latch locking bar or latch latch. The strike plate can be designed as a flap closing plate in the form of a flat profile, which is mounted on the front side of the door frame.

In addition, a closing strip for building doors is known with a closing piece provided on the closing strip body, which forms the catch catch,
wherein a sliding surface for the case forming slider is provided on the closing strip. It may be a plastic molding, which is held on the closing bar body and / or on the closing piece (cf. DE 200 03 401 U1 ).

Moreover, from the DE 102 15 014 A1 a closing strip with an electric door opener for a door lock, in which in the passage opening with a predetermined inclination of the one opening edge angled sliding bar is arranged for the latch, said sliding bar engages through a Fallenausnehmung in the opener case. At the end of the angled sliding bridge is followed by a substantially parallel to the strip front side extending web part. Further, on the strip front side, a cover framing the passage opening is arranged with a passage corresponding opening. This cover may be configured for outward opening doors and have a side mounting plate adjacent to the aperture. The cover with the side mounting plate is placed as it were on the closing strip.

Finally, one knows from the DE 101 47 308 A1 an outer door for use as access to a garage with a movable door leaf and a frame, which has frame spars, wherein the door leaf has a latch and one of the frame spars in a closing area a trap receptacle as an abutment for the latch. The Fallenaufnahme can be designed as a cup-shaped insert, which is preceded by an angle plate as it were protective cover for the frame. This cover can be made of plastic.

The invention has for its object to provide an inexpensive closing strip assembly of the type described above, which is universal usable closing strip characterized by minimal noise during the closing movement and minimized wear.

To solve this problem, the invention teaches a closing strip assembly for a door lock with a fastened to a door frame closing strip with a passage opening for a rückdrückbare latch of a door lock arranged on a door, wherein in the region of the passage opening a latch catch is arranged, which of the latch in the closed position is being attacked
and with a sliding surface arranged upstream of the latch in the closing direction, on or at which the latch slides along in the course of the closing movement,
wherein the sliding surfaces is formed by a separately formed sliding profile, which is arranged in the closing direction in front of the closing strip and is preferably fastened or attachable to the door frame, and
wherein the sliding profile is made in several parts, for example in two parts, and has a sliding plate and a sliding ramp adjustable relative to the sliding plate.

According to the sliding profile is a multi-part, for example, formed in two parts. It has a sliding plate on the one hand and an opposite the sliding plate adjustable sliding ramp on the other. The invention is based on the recognition that, especially in profile systems because of the not insignificant tolerances a safe door suit is ensured by the fact that the standard closing strips are provided with adjustable Fallteileinsätzen or closing pieces. The compensation of such tolerances by adjusting the strikers leads to different distances between the front frame edge on the one hand and the closing piece leading edge on the other hand,
wherein such tolerances can be compensated according to the invention by the adjustable sliding ramp, so that there is always the possibility that the slide on the one hand flush with the frame leading edge and on the other hand with the Schließstückvorderkante. Always unwanted noise and unwanted wear are reliably avoided.

Conventional closing strips are universally applicable both for inwardly opening and outward opening doors, when dispensed with an integrally formed on the closing strip sheet metal tabs and instead a separately trained sliding profile with sliding surface is used, which is substantially independent of the closing strip, for example, directly or indirectly Door frame is attached. In this respect, an additional component of cost-effective and at the same time low-friction material is made available, which is screwed into the sliding region of the trap. The sliding profile protects the frame surfaces and minimizes the noise in the course of striking the latch. This is especially true when the sliding profile is made according to a particularly preferred embodiment as a separate component or as a separate assembly made of plastic.

The case causes hardly any noise when hitting the plastic part and slides smoothly and smoothly over the slope of the sliding ramp or slide into the closing part. Ramp support and slide ramp are preferably firmly connected to each other, for example, as a one-piece component (made of plastic). Basically, however, it is also possible to manufacture the sliding profile of other material, for example of metal, since then, in any case, an effective protection against damage to the door frame is given. However, to minimize the noise development, embodiments of, for example, plastic or plastic coating are preferred. Moreover, it is expedient if the slide profile extends substantially from the frame front edge of the door frame into the region of the closing edge leading edge or the closing piece leading edge. Frame leading edge here means within the scope of the invention, the edge of the door frame against which the door or a peripheral door seal strikes in the course of closing the door. This may in particular be a profile web extending transversely to the closing direction.

Disturbing noise developments in the region of the frame leading edge as well as wear or damage are avoided in particular if the sliding profile according to a particularly preferred embodiment of the invention, the frame leading edge or the profile web in cross section or in a side view with a stop projection covers. The slide profile is thus formed in the region of the frame leading edge stepwise with a stop projection, the slide profile or its stop projection in cross-section or in the side view substantially flush or flush with the frame leading edge or the profile web. Consequently, it is not necessary for the slide profile or its stop projection to protrude beyond the frame leading edge. A further development of the invention has recognized that it is sufficient due to the shape and kinematics of the lock latch when the sliding profile or its stop projection in cross-section flush with the frame leading edge or the profile web, without causing it to contact the latch with the metallic profile frame front edge can come. In this respect, damage or functional impairment of the door seal, which rests against the door frame, are avoided without further ado.

According to a preferred embodiment of the invention, it is provided that the sliding profile engages under the closing strip leading edge or the closing piece leading edge at least in some areas. Furthermore, it is expedient if the sliding profile rests against the closing edge leading edge or the closing piece leading edge at least in regions and is flush with or flush with it in cross-section. For this purpose, it may be useful if the sliding on the one hand a sliding plate and on the other hand arranged on or on the sliding plate sliding ramp having in the closing direction increasing sliding surface, wherein the sliding ramp preferably bears against the closing edge leading edge or Schließstückvorderkante and flush with this. In this embodiment, it may be expedient if the sliding plate engages under the closing strip leading edge or the closing piece leading edge at least in certain areas. In any case, a perfect sliding surface is provided by the sliding ramp, which is substantially flush or flush with the Schließstückvorderkante so that even in the closing bar or a closing piece unwanted noise is reliably avoided.

As a result of faultless function and cost-effective construction, sliding profiles are particularly suitable in which the sliding plate has an opening into which the sliding ramp arranged on a ramp support can be inserted or inserted, so that the sliding ramp, as it were, penetrates the opening from below. The ramp carrier lies against the sliding plate from below. It is expedient if the ramp carrier and / or the sliding plate have latching elements for fixing the sliding ramp in a predetermined position. It is particularly advantageous if, first of all, the ramp carrier has several latching noses on its upper side facing the sliding plate. Alternatively or additionally, the slide plate may have locking lugs on its underside facing the ramp support, which optionally correspond to the latching lugs of the ramp carrier. In any case, in the course of installation, the ramp carrier and thus also the sliding ramp can be displaced relative to the sliding plate, whereby a perfect fixing of the sliding ramp in or on the sliding plate is ensured after assembly by the interlocking locking lugs. In this case, the closing piece itself can be adjusted by means of locking lugs relative to the striking plate or door frame. Preferably, the distance between the individual locking lugs of the sliding profile and / or the ramp carrier corresponds to the distance between the latching lugs of the closing piece, so that is worked with the same screening. This allows shifts of the closing piece can be compensated exactly in a simple manner. According to a further proposal of the invention, the sliding plate is wedge-shaped in cross section with decreasing thickness in the closing direction.

If the door frame as a profile frame from at least a first hollow profile (made of metal) and at least a second hollow profile (made of metal) is formed, wherein the two hollow sections by means of at least one insulating web (made of plastic) are interconnected, the sliding profile can be placed on the insulating bar and optionally attached to the insulating bar, for example screwed. The insulating webs made of plastic care for a thermal separation between outer profile and inner profile and therefore they should ensure a good thermal coefficient. Due to the design of the sliding profile made of plastic in particular, this thermal separation is maintained particularly reliable, even if the sliding profile is fixed in the region of the insulating bar and bridges this. In addition, a particularly simple attachment of the sliding profile on the insulating web also made of plastic manages.

The sliding profile is of particular importance. It can be used together with a conventional closing strip to form a closing strip assembly according to the invention.

The particular advantages of the invention can be seen in that in particular the front frame profile edge can be reliably protected. In addition, a low-noise trap inlet is ensured and avoided occurring in the prior art two times "clunk". Nevertheless, no cold bridges are formed, since the sliding profile is completely made of plastic, for example. Standard Schließleisten can without constructive changes together with the sliding profile to form the Closing strip units according to the invention are used. The same (small) cutout can also be used for closing parts with automatic or electric door opener. Milling means here an opening or opening in the profile of the door frame, in which the electric door opener protrudes. Regarding this cutout, no changes compared to the previously used closing strips are required, regardless of whether working with or without sliding profile. Even with such electric strikes the inwardly directed closing strip can be used. Overall, the solution according to the invention is distinguished not only by its perfect function, but in particular by low manufacturing and assembly costs.

In the figures, a closing strip assembly 1 is shown for a door lock. The closing strip assembly 1 has, first of all, a closing strip 3 fastened to a door frame 2, the closing strip 3 having a passage opening 4 for a push-back latch 5 of a door lock arranged on a door or a door leaf 6. In the region of the passage opening 4, a latch catch 7 is arranged, which is engaged behind by the latch 5 in the closed position. This will be based on a comparative analysis of the Fig. 3a and 3b directed.

The striker assembly 1 further includes a latching surface 8 upstream of the latching catch 7 in the closing direction, on or on which the latch bolt 5 slides in the course of the closing movement. This sliding surface 8 is formed by a separately formed sliding profile 9, which is arranged in the closing direction R in front of the closing strip and secured to the door frame. In a plan view from the inside to the door frame 2, the sliding profile 9 is thus positioned next to the closing strip 3. The sliding profile 9 is made of plastic. In the exemplary embodiment, a catch member forming a latch receptacle 10 with latching edge 11 or latching lug is used as latch latch 7 in the passage opening 4. The slide profile 9 extends substantially from the frame front edge 12 of the door frame 2 into the region of the closing edge leading edge, which is formed in the exemplary embodiment of the closing piece leading edge 13. Frame front edge 12 means the door or a door seal assigned and designed as a profile web front edge 12 of the door frame 2, wherein the peripheral door seal 14 in the closed position against the front edge frame 12 and the frame front surface 15 abuts (see. Fig. 3b ). The slide 9 is formed in step-like manner in its front region associated with the frame front edge 12, wherein the slide profile 9, the frame front edge 12 in cross section with a stop projection 16 covers, in such a way that the sliding profile 9 or the stop projection 16 terminates in cross-section substantially flush with the frame leading edge 12. In this respect, a comparative analysis of the Fig. 3a and 3b clearly that the lock latch 5 in the course of the closing movement no longer abuts against the metallic frame front edge 12 but exclusively against the projecting stop projection 16 made of plastic, so that on the one hand minimizes wear and on the other hand disturbing noise is reliably prevented. Nevertheless, the operation of the seal 14 is not affected because the stopper projection 16 is flush with the frame leading edge 12 and does not protrude beyond.

It is further provided that the slide profile 9 engages under the closing piece leading edge 13. Nevertheless, it is provided that the sliding profile 9 abuts in regions against the Schließstückvorderkante 13 and thereby flush in cross-section or flush with the surface of the closing piece 10. The sliding profile 9 has, on the one hand, a sliding plate 17 engaging under the closing piece edge 13 and, on the other hand, a sliding ramp 18 arranged on or on the sliding plate 17, with a sliding surface rising in the closing direction. This slide ramp 18 is now against the Schließstückvorderkante 13 and flush with this, while the slide plate 17, the locking piece 10 optionally engages under.

According to the sliding profile 9 is a multi-part, in the embodiment substantially in two parts, formed. It consists on the one hand of the already described sliding plate 17 and on the other hand from the sliding plate 17 adjustable sliding ramp 18. The sliding plate 17 has an opening 19, in which the sliding ramp 18 is used, the sliding ramp 18 itself to a ramp support 20 (in one piece ) is attached. The slide plate 17 is in the FIGS. 5 to 7 shown while the ramp support 20 with the sliding ramp in the FIGS. 8 to 10 is shown. That from these two components Composite slide 9 is, for example, in Fig. 4 shown. The Fig. 1, 2 and 3a, 3b show the sliding profile 9 in the mounted state on a door frame 2 in the region of a closing strip. 3

Ramp support 20 on the one hand and sliding plate 17 on the other hand are each formed with locking elements 21, 22 for fixing the sliding ramp 18 in a preceding position. The ramp support 20 in this case has on its sliding plate 17 associated upper side a plurality of latching lugs 21, while the slide plate 17 on its the ramp carrier 20 associated underside also corresponding locking lugs 22 has. The slide plate 17 is wedge-shaped in cross-section with decreasing in the closing direction R thickness.

How the particular FIGS. 3a and 3b show, the door frame 2 is formed as a profile frame of a first hollow section 2a made of metal and a second hollow section 2b made of metal, wherein the two hollow sections 2a, 2b are interconnected with the interposition of insulating webs 23 and plastic insulating strips. The same applies to the illustrated door 6, which also consists of such profile frame 6a, 6b. The sliding profile 9 is placed on one of these insulating webs 23 and fastened thereto by means of screws 24. For this purpose screw openings 25 are provided in the sliding profile or on the sliding plate.
