Description

The The invention relates to a door leaf for one as a completion of a building suitable front door with a door leaf frame and a sandwich panel held as a door panel, consisting of a motif plate and a cover plate and insulation material is formed in between. Such door leaves are as part of on available on the market Front doors known.

The EP 0 476 978 A1 discloses a door construction and a method of making the same. The door construction comprises a doorframe of four frame spars and a polystyrene foam sheet supported on the door frame as a door panel. In a first embodiment, on the side facing the outside, an outer skin is coplanarly adhered to both the outside of the panel and the outside of the door frame. On the inside of the plate, an inner skin is glued, which is glued to a thigh-like door stop. In addition, the outer skin lies directly on the outside of the door frame. In a second embodiment, the inner skin is coplanarly adhered to the inside of the panel and to the inside of the door frame.

The following is based on the attached here 3 - 5 a front door to an in-house state of the art described. 3 represents an approximately central vertical section and 4 a horizontal section through the front door. 5 shows a horizontal section of an edge region of a door leaf used in this door.

The total with 10 marked front door has a door frame 12 and one about door hinges 14 pivotally held door leaf 16 , The door leaf 16 is again through a door leaf frame 18 and a door panel inserted therein 20 educated.

The door frame 12 and the door leaf frame 18 are each formed from light metal profiles, in particular aluminum profiles. The individual spars of the two frames 12 . 18 are each made of two hollow sections 22 . 24 , here made of aluminum alloy, with connecting bars 26 formed in between. The connecting bridges 26 are from poor heat dissipation of the material (eg plastic) to avoid thermal bridges. That way is the front door 10 formed as an external finish for a house and has a relatively high k-value.

How best 5 can be seen, the door panel is constructed as a sandwich panel. It has a motif plate 28 , an inside plate directed to the inside of the front door - in the following cover plate 30 called - and insulation material 32 between the two plates 28 . 30 on. The insulation material 32 and the cover plate 30 are in the door leaf frame 18 used. The motif plate 28 stands over the insulation material 32 and the cover plate 30 and is on the door leaf frame 18 this partially overlapping laid. To avoid thermal bridges, as mentioned above, the door leaf frame 18 as composite profile with the two hollow profiles 22 . 24 and the connecting webs 26 formed between them. The fastening of the door panel 20 done by gluing the above motif plate 28 with the door leaf frame 18 and by a screw connection 40 on the inside.

The motif plate 28 is important for front doors, as such front doors are primarily bought because of their design. The motif plate 28 carries a certain (exterior) color or a specific pattern or is visually designed by inserts such as glass elements (which may possibly also extend through the insulation material and the cover plate) or by attached elements such as metal plates, etc .. In industrial manufacturing can be compared with equivalent door leaf frame through a whole range of available motif plates 28 a variety of very different looking front doors are created.

For the production of in 5 shown door leaf is first the door leaf frame 18 prepared. The stocked stock motif plate is cut to the appropriate size. This is the insulating material 32 and the cover plate 30 according to the inner dimension of the door leaf frame 18 tailored. This is done with play, so that the cover plate 30 and the insulation material 32 easy in the door leaf frame 18 can be inserted and costs that would be incurred at lower tolerances, can be saved. The cutting edge of the motif plate 28 is surface treated after cutting. This is done differently depending on the material used. What is common is that the cutting edges are mitigated to avoid risk of injury and optically high quality. Often also a repainting takes place.

The in 5 shown door leaf frame 18 is with an inwardly projecting edge 34 provided in order to accommodate other door panels instead of the sandwich panel shown. This wing edge 34 is before the insertion of the door panel shown here 20 with the motif plate 28 shortened. The after fixing the sandwich panel 36 resulting joints between the motif plate 28 and the door leaf frame 16 be with silicone 33 sealed. The gap between the cover plate 30 and the insulation material 32 on the one hand and the door leaf frame on the other hand is a 1.5 mm thick sheet steel 38 covered with Z-profile, what the internal screwing of the sandwich panel 36 by means of self-tapping screws 40 he follows.

outgoing It is the task of the prior art described above the invention, a door leaf and a door provided with it visually high quality yet cost effective and faster to produce with less effort.

These Task is through a door leaf solved with the features of claim 1.

A provided with the door leaf according to the invention front door and a manufacturing method for the door leaf are the subject of the subsidiary claims. advantageous Embodiments of the invention are the subject of the dependent claims.

According to the invention Sandwich plate not as in the above prior art partially in the door leaf frame introduced, rather, it is an execution the invention, the sandwich panel on the door leaf frame as a whole on.

• • Die Motivplatte steht nicht über, es entstehen keine Fugen und Versätze.
• • Da zwischen der als Außenabschluss der Haustür geeigneten Motivplatte und dem Türblattrahmen noch das Dämmmaterial und ggf. die Deckplatte eingefügt ist, gibt es keine Kältebrücken zwischen der Innenseite des Türblattrahmens und der Türblattaußenseite. Man kann somit auf ein Verbundprofil für den Türblattrahmen verzichten. Der Türblattrahmen kann aus einfachen (Metall-)Hohlprofilen hergestellt werden.
• • Es werden keine Glasleisten oder inneren Leisten wie z. B. das oben genannte Stahlblech benötigt;
• • Das Zuschneiden der Sandwichplatte ist wesentlich vereinfacht, da die Motivplatte kein eigenes Zuschneidemaß und keine Sonderbearbeitung mehr benötigt.
• • Dadurch kann die Herstellung kostengünstiger und wesentlich schneller erfolgen.
• • Bisher musste man im Türblattrahmen stets einen unteren Sockel vorsehen, um genügend Stabilität zu haben. Mit der Erfindung kann der Türblattrahmen als durchgängiger Rohrrahmen ausgeführt werden. Der Türblattrahmen kann vierseitig umlaufend gleichgestaltet sein.
• • Aufgrund der besonderen Konstruktion können die Motivplatte 28 und die Deckplatte 30 gleichgestaltet sein. Dies verringert die Herstellkosten für die Sandwichplatte.
• • Durch die Möglichkeit der Gleichgestaltung der Motivplatte und der Deckplatte können beide Seiten wahlweise als Motivplatte benutzt werden. Man kann so mit ein und derselben Sandwichplatte und verschiedene Muster tragenden Oberflächen auf beiden Seiten einfach durch wahlweises Verwenden einer der Platten als Motivplatte ein unterschiedliches Aussehen erzeugen.

This has the following advantages:

• • The motif plate is not over, there are no joints and offsets.
• • Since between the outside of the front door suitable motif plate and the door leaf frame, the insulating material and possibly the cover plate is inserted, there are no cold bridges between the inside of the door leaf frame and the door leaf outside. One can thus do without a composite profile for the door leaf frame. The door leaf frame can be made of simple (metal) hollow profiles.
• • There are no glazing beads or internal strips such. B. requires the above-mentioned steel sheet;
• • The cutting of the sandwich panel is considerably simplified, as the motif panel no longer requires its own cutting allowance and no special machining.
• • As a result, the production can be made cheaper and much faster.
• • So far, you always had to provide a lower base in the door leaf frame to have enough stability. With the invention, the door leaf frame can be designed as a continuous tube frame. The door leaf frame may be the same shape on four sides.
• • Due to the special construction, the motif plate can 28 and the cover plate 30 be the same. This reduces the manufacturing costs for the sandwich panel.
• • Due to the possibility of the design of the motif plate and the cover plate, both sides can optionally be used as a motif plate. It is thus possible to produce a different appearance with one and the same sandwich panel and different pattern-bearing surfaces on both sides simply by selectively using one of the panels as a motif panel.

Preferably the sandwich panel is placed on the door leaf frame so that in total, with all its components more than 80%, in particular 95% -100% in the intended use outward directed surface covered the door leaf frame.

at a door leaf With the features mentioned above can be a faster and cost-effective Achieve production by one on the door leaf frame molded or fixed cover strip a cutting edge of the motif plate and / or covers an entire front side of the sandwich panel. In this way you can save reworking of the cut edges. Such finishing operations can take a few working days, just think of the time to cure Paints or the like. In this way, the front doors according to the invention could by some Days faster than before individually after becoming aware of the Customers desired Dimensions for the front door custom made and delivered.

Especially preferred is a combination of these two measures, wherein the sandwich plate only a total without especially for the motif plate measure to have to, must be cut and placed directly on the door leaf frame and is attached, in which case the cut edges by the cover strip is covered. A si chere attachment of the motif plate and / or the entire sandwich panel is achievable in that in addition to the bonding is still a profile element is provided, the at least one (side) edge, preferably several or all edges encompasses all four sides of the sandwich panel. This can be done Set the motif plate even if the Dammmäterial something softer is.

It is particularly preferred if the aforementioned cover strip is designed as such profile element. The cover strip then has both a cover function and a fastening function. The covering serves on the one hand optical reasons to cover the possibly irregularly acting cutting edges and the insulating material; On the other hand, by covering an access to the possibly sharp-edged cut edges with the resulting risk of injury is avoided. As a particularly easy to produce and mount attachment of the cover and / or the profile element is a clamp connection and in particular a locking connection or clip connection preferred. The cover strip or profile strip preferably has a U-profile. A first leg of the profile can be used to attach the strip to the door leaf frame. The second leg engages around the sandwich panel and secures it. The first Leg can be clipped, for example, in a groove on the door leaf frame. The second leg advantageously serves as a support for a door seal, which is fastened to the door frame of the door leaf provided with the door leaf according to the invention.

One embodiment The invention will be explained in more detail with reference to the accompanying drawings. The attached Drawings show in

1 a side portion of a front door according to the invention in horizontal section along the line 1-1 of 2 ;

2 an interior view of the front door according to the invention;

3 a vertical section through a previously known in an in-house state of the art door;

4 a horizontal section through the known front door of 3 ; and

5 a border area of one in the known front door of 3 and 4 used in the prior art door leaf in horizontal section;

6 a lower portion of a front door according to the invention in vertical section along the line IV-IV of 2 ,

A front door according to the invention 10 with door frame 12 and door leaf 16 is in the 1 and 2 shown. The same reference numerals are used for comparable parts as in the previously described door according to the prior art. For the basic characteristics of these parts and hereafter not mentioned features of the front door is also on the previous explanations and the graphic representation of the in the 3 - 5 referenced prior art.

The door frame 12 is also in the front door according to the invention 10 as in the prior art according to the 3 - 5 built up.

The construction of the door leaf 16 however, it is significantly different. The door leaf frame 18 is not composite profiles, but in the illustrated embodiment by spars from a one-piece hollow profile 42 made of extruded light metal, in particular an aluminum alloy. The sandwich plate 36 has with the cover plate 30 , the outside motif plate 28 and the insulation material 32 a uniform external dimension. motive plate 28 , Insulation material 32 and cover plate 30 are in a Zuschneideschnitt on the outer dimensions of the hollow section 42 of the door leaf frame 18 tailored. The inward-facing surface of the cover plate 30 , more precisely, the away from the motif plate 28 directed or the motif plate 28 opposite surfaces 44 in the area of the edges of the sandwich panel 36 are on the outward facing surface 46 of the door leaf frame 18 put on and glued on (glue 72 ). The essentially stepless limited end faces 70 the sandwich plate 36 are with a cover strip 48 covered.

The cover strip 48 is formed as a profile element and has a substantially U-shaped profile with a first leg 50 , a second leg 52 and a jetty 54 between. With the first leg 50 is the cover strip 48 in a groove 56 on the door leaf frame 18 clipped. For this purpose, the groove 56 one to a narrower insertion channel 58 subsequent extended area 60 , The first leg 50 is hen with a locking nose hen, which is the stage between the insertion channel 58 and the extended area 60 can latch behind.

The jetty 54 covers the cut edges of the motif plate 28 and the cover plate 30 from. The jetty 54 Also covers any joints between the sandwich panel 36 and the door leaf frame 18 from. In addition, the jetty covers 54 the insulation material 32 from. The frontal wide surface 62 of the footbridge 54 is optically high-quality designed as a visible surface. The cover strip 48 or the visible surface is preferably optically to the respective motif plate 28 customized. There is an assortment of motif plates for this purpose 28 or finished sandwich panels 36 and a corresponding range of color-matched cover strips 48 ,

With the second leg 52 surrounds the cover strip 48 the motif plate 28 , Characterized in that on all four sides a corresponding shape of the door leaf frame 18 with cover strip 48 is present, is the sandwich panel 36 edged on all sides. The outward side of the second leg 52 also serves as a support for a seal 64 which on the door frame 12 at a corresponding projection 66 the outside hollow profile 22 is attached.

For the production of in 1 shown door leaf 16 The procedure is that the stocked sandwich panel 36 with motif plate 28 on the external dimension of the hollow profile 42 of the door leaf frame 18 in one step by cutting motif plate 28 , Cover plate 30 and insulation material 32 is tailored. The motif plate 28 is then on the previously completed door leaf frame 18 so laid on and glued on, that the outward directed surface 46 of the door leaf frame 18 essentially completely covered - wing-covering Ausstat -. Subsequently, the cut edges 68 through that as a cover strip 48 covering serving clip profile. This avoids reworking the motif plate and thus saves many working days.

This in 1 illustrated door leaf 16 creates a visual enhancement, as the motif plate 28 not over the sash 18 stands and no joints and misalignments arise. In the prior art, there is still a step for the seal on the outer corner edge 64 , This is inventively avoided.

This in 1 illustrated door leaf 16 is cheaper to produce, because it is sufficient a simple hollow profile 42 instead of from the hollow sections 22 . 24 and the jetties 26 formed composite profile. No glazing beads are needed and you do not need any special processing of the motif plate 28 , Simple cutting is enough. Due to the simpler production, one can make the custom-made front door according to design and dimensional specifications 10 deliver faster. A faster delivery is also due to the fact that the cut edges 68 no longer need to be surface treated.

The in 1 The section shown is representative of the two vertical and the upper horizontal side. Below is, as in the prior art according to no composite profile for the door frame 12 and a spar provided for the door leaf frame, with appropriate support of the sandwich panel and cover by the cover strip 48 ,

The lower area is in the 6 refer to. Although for the lower portion of the door leaf frame also a separate, larger, that can be used in the intended use higher rail, the same Türblattrahmenholm is used in the illustrated example as on the sides and top. This saves on production costs and storage costs through the same-part strategy. An in 1 illustrated projecting area 74 for a door seal 76 for sealing the lateral and upper joint is at the lower hollow profile 42 simply removed. A frontally provided C-shaped groove 78 serves to accommodate the lower door seal 80 , which is shown here only as an example and very schematically. The bottom door seal 80 could also be designed significantly wider and in addition to corresponding brackets on the wide surface 62 be attached to the bridge. It could also be stuck there. Otherwise, the lower door leaf area is the same as the side and the upper door leaf area.

Like from the 1 and 6 can be seen, are the motif plate 28 and the cover plate 30 each represented the same in the illustrated embodiment. The sandwich plate is so also around a parallel to its plane extending axis rotated by 180 ° usable, so that the cover plate as a motif plate and the motif plate 28 is used as a cover plate. The visible surface of the motif plate 28 has a different design than the visible surface of the cover plate 30 , So you can with one and the same sandwich plate 36 simply create different-looking house doors through optional orientation.
