The hinge receiving groove (3) is equipped with at least one step (3A) running approximately parallel to said groove, into which the fixing screws (8B) of the first strap hinge tab (2B) can be screwed and which forms a first receiving area (3C) at the base of the groove for housing at least one section of the articulation region (2A) of the strap hinge (2) and a second receiving area (3B) on the exterior of the groove for housing said first strap hinge tab (2B). The hinge receiving grooves (3) form a third receiving area (3D) in their groove border zone, which lies opposite the step (3A), said area housing the second strap hinge tab (2C). The fixing screws (8C) of the second strap hinge tab (2C) can be screwed into the groove wall (3E) of the third receiving area (3D).

Description

The invention relates to a sectional door, consisting of articulated section panels.

In such sectional doors, a plurality of section panels are hinged together along horizontal lines. Hinge straps, which consist of a joint area and two mutually connected attachment areas (hinged hinge lugs) allow the mutual pivoting of the section panels. The adjacent in the joint zone section panel edges of such sectional doors are provided with mutually intermeshing webs and recesses, the z. B. serve as effective from the Toraußenfall Fingerklemmschutz and ensure the mutual pivoting of the section panels for a certain degree of coverage of the adjacent Toraußenseiten in the joint area. As lightweight panels for stability, but also for heat insulation reasons a considerable thickness, of z. B. 45 mm, you moved the pivot point, d. H. the pivot axis into the panels, d. H. between the outer and inner panel surface. As a result, the overlap length can be kept at tolerable designed as an external Fingerklemmschutz webs and recesses within tolerable limits.

For this purpose, one from the DE 39 38 021 C2 known sectional door on its inner door side one of adjacent section panels in the joint area together formed hinge receiving groove on (Fig. 8). This takes up the joint area of the hinge hinge. In order to be able to safely initiate the considerable forces occurring on the hinge strap tabs when moving the sectional door in the adjacent section panel edge regions and to ensure a sufficient longevity of the screw, the two hinge tabs of such a hinge strip are led out of the hinge receiving groove and extending parallel to the panel surface where Fixing screws are screwed into suitable Materialaufdopplungen for transmission of the aforementioned forces. - Such a sectional door, however, has the disadvantage that by the inwardly laying the pivot axis of the section panels, ie between the two inner and outer panel surface, the aforementioned hinge receiving groove is required. This is only on the short sections in which the hinges are filled. The remaining length portions of the hinge receiving groove remain empty and thus represent a finger trap risk when opening the door, because the groove edges move towards one another during the mutual pivoting of the section panels. This problem becomes all the clearer the larger the diameter of the hinge region of the hinge straps and the farther the hinge axis is shifted away from the inner surface of the door to the center of the panel thickness.

In the above types of section panels, it has not been possible to meet the conflicting requirements, the user safety, ease of assembly, the longevity of the hinge fasteners and - with attractive appearance - the inexpensive manufacturability.

Based on this, the invention has the object, in the above-described sectional doors, as they in particular DE 39 38 021 C2 are known to create a visually appealing security solution with little effort. Another aspect of the invention is the longevity together formed Schamieraufnahmenut on (Fig. 8). This takes up the joint area of the hinge hinge. In order to be able to safely initiate the considerable forces occurring on the hinge strap tabs when moving the sectional door in the adjacent section panel edge regions and to ensure a sufficient longevity of the screw, the two hinge tabs of such a hinge strip are led out of the hinge receiving groove and extending parallel to the panel surface where Fixing screws are screwed into suitable Materialaufdopplungen for transmission of the aforementioned forces. - Such a sectional door, however, has the disadvantage that by the inwardly laying the pivot axis of the section panels, ie between the two inner and outer panel surface, the aforementioned hinge receiving groove is required. This is only on the short sections in soft, the hinges are filled. The other lengths of the Schamieraufnahmenut remain empty and therefore represent a Fingererklemmschutzrisiko when Toröff, because the groove edges to move towards each other in the mutual pivoting of the section panels. This problem is all the clearer, the larger the diameter of the hinge region of the hinge straps and the farther the hinge axis is moved away from the Torinnenfläche away to the center of the panel thickness.

From the EP 1 072 750 A2 are sectional doors made of lightweight panels known in which used folded foamed sheet material and the hinge are screwed from the inside flat on the panel outside. Because of the typical offset of the hinge region of rolled hinge bands, the section edge receiving the inwardly cranked hinge tab has a continuous receiving fold with the hinge axis in the plane of the posterior section surface.

From the non-generic EP 1 158 133 A2 a sectional door made of rolled sheet metal is known in which adjacent section edges form a trapezoidal in cross-section hinge receiving groove, wherein the hinge tabs of the hinge are screwed to the trapezoidal legs and these trapezoidal legs are reinforced by plane stiffening plates on its back.

From the also not generic WO 95/24536 the applicant is known a sectional door, in which the section edge are made of a dimensionally stable extruded profile, that has a plurality of undercut longitudinal grooves for the sliding receiving hinge bands, so that the hinge forces are already absorbed by the undercuts.

In the types of Leichtbausektionspaneelen described above, it has not yet been able to meet the conflicting requirements, the user Sicherhelt, the ease of installation, the longevity of the hinge fasteners and - with attractive appearance - the cheap manufacturability.

Based on this, the invention has the object, in the above-described sectional doors, as they in particular DE 39 38 021 C2 are known to create a visually appealing security solution with little effort. Another aspect of the invention is the longevity of the To reach the hinge joints at the same time easier and less experienced by staff with appealing result executable mountability in such sectional doors whose section panels total, ie also in the section edge region of a sandwich material, such as a foamed core, the torinnere and toräußere surface of a sufficient unbreakable surface material, such as light metal sheet or plastic plates is formed, which surface material is also used by corresponding folds to form the relatively complex section panel edges. These section panel edges have a smaller thickness in many areas than the main area of the section panels. At the same time, however, the forces which occur at the hinge bands must be introduced into the section panel edges via fastening screws in these areas.

To achieve the aforementioned object and also of the further aspect of the invention, a sectional door with the features of claim 1 is proposed.

In such a sectional door we put the whole hinge strap including the hinge strap tabs and, preferably, also including the heads of the fastening screws within a specially designed hinge receiving groove. Despite the correspondingly large in cross-section ausfallenden hinge receiving groove is achieved that on the Toraußenseite mutually interlocking webs and recesses of Sektionspaneelkanten can ensure effective external Fingerklemmschutz without a deterioration in the introduction of force from the hinge bands on the mounting screws in the Sektionpaneelkantenbereiche to buy is. For this purpose, a comparatively complex structure of the hinge receiving groove is proposed, according to which three individual but interconnected receiving spaces are created by means of a groove-parallel stage, in which the fastening screws of the one of the two hinged hinge tabs, as screwed into an integrated into the panel profile mounting base. The (second) receiving space located above this step from the outside receives the one hinge strap. The lying next to the stage, seen from the outside deeper, ie beginning at the groove bottom first receiving space takes on at least a portion of the joint region of a sufficiently large calibrated hinge band. The third receiving space serves to receive the second hinge strap flap and is located in the groove edge zone of the hinge receiving groove opposite the step, wherein the fastening screws of the second hinge strap flap can be screwed into the groove wall of the third receiving space. The mounting screws are therefore not clamped in this purpose specially designated grooves, but so, as from the DE 39 38 021 C2 known, screwed into the "meat" of the sectional panel.

In order to find similarly favorable power transmission ratios for the fastening screws for the second hinge strap, as in the first hinge strap, it is contemplated (alternatively) to provide either one of the aforementioned hinge hinge groove second stage opposite the first stage or for that second hinge strap flap , as particularly preferred, to arrange the fastening screws of the second hinge strap receiving groove wall of the third receiving space to the panel surface obliquely inclined and here, as very particularly preferred, when straight straight hinge hinge first extended to the opposite (in Torschließlage) obliquely inclined, in particular angled second hinge strap flap use. Thus, the power transmission surface of the second hinge strap tab for the mounting screws is more or less flat on the obliquely inclined groove wall of the third receiving space in the hinge receiving groove on / on.

In order to continue to improve even extremely lightweight foamed section panels, which also have foamed Paneelsektionskantenbereiche, various folds of the sheet surface material of the section panels for receiving fastening screws, including undercut zones are provided according to claims 4 to 7, whose features of independent functional importance and independent of the Fulfillment of all features of the main claim. This also applies to panel stiffening profiles, which can be integrated into the hinge receiving grooves particularly advantageous or can be fixed in this.

An alternative stiffening possibility of the section panel edge regions for improved introduction of the forces transmitted by the hinge fastening screws is achieved by a dowel-like design according to claim 9, which are also of independent functional importance in this respect without the realization of all features of claim 1.

The aforementioned and the claimed and described in the embodiments described components according to the invention are subject to their size, shape design, material selection and technical design no special conditions of exception, so that the well-known in the field of application selection criteria can apply without restriction.

Fig. 10A / B

a fifth embodiment of a sectional door in the representation of Fig. 2A / B, wherein an additional stiffening means in Fig. 10B is shown.

In the embodiment according to FIG. 1, the section panels 1A, 1B shown in section in the region of adjacent edges consist of a sandwich construction in which sheets of light metal formed by folding form the panel body including the edge region and are foamed in a known manner, which - for clarity - only in Fig. 1 but not explicitly shown in the following figures. At the Toraußenseite A shown on the left in the drawings and subsequent drawings, a Fingerklemmschutz in the form of mutually formed on the section panels 1A, 1B and mutually interlocking webs 4A, 4B and recesses 5A / B are provided which extend over the entire panel width of the in the drawing, only a narrow strip is shown. Hinged hinges 2 on the right inside in the drawing shown inside the door I allow the mutual pivoting of the adjacent section panels, as z. B. in Fig. 2B, 4B, 6B, 9B and 10B is shown. They are housed entirely within a hinge receiving groove 3 within the Torblattdicke and consist of a hinge portion 2A, an upper hinge strap 2C and a lower hinge strap 2B, which are assigned to the higher or lower section panel 1A and 1 B.

The hinge receiving groove 3 has in its interior a groove parallel arranged stage 3A with an approximately panel-parallel contact surface for the lower hinge strap flap 2B. In this stage, fastening screws 8B are screwed in to fix the lower hinge strap lobe 2B and to transmit forces when moving the gate. Inside the stage 3A is this reinforced by a flat material reinforcement in the form of a material fold 9B, to receive the fastening screw 8B and to reinforce the step 3A. A corresponding material fold 9C is provided in the lower edge region of the higher section panel 1A for reinforcing the tightening portion of the fastening bolts 8C of the upper hinge hinge lobe 2C. Further material folds 9A and in the region of undercut zones 10A and 10B will be explained in more detail below.

Above the step 3A, that is near the groove entrance, a (second) receiving space 3B is formed in the hinge receiving groove 3, in which the one hinge strap 2B and the head of the fixing screw 8B are completely accommodated. In addition to stage 3A, a first receiving space 3C is located at the bottom of the groove, namely for accommodating at least one part (usually the inner half) of hinge area 2A of hinge band 2. In the present case, a panel-parallel root extension or limb of upper hinge band flap 2C in FIG added to this first recording room. The step 3A and the groove bottom thus define the second and first receiving spaces. A third accommodating space 3D is connected to the first accommodating space 3C on the hinge receiving groove 3C opposite to the step 3A. It is limited to the (upper) edge of the groove by a groove wall 3E inclined at an angle of approximately 45 ° to the panel surface, which serves as a contact surface of the hinge strap flap 2C accommodated in the third receiving space 3D. The fastening screw 9C is screwed through the hinge plate into this groove wall 3E and subsequently into the material fold 9C, the screw head also being completely received by the third receiving space 3D.

Finally, from Fig. 1, a provided in itself of a rigid material, substantially in itself flat with a hinge-like profiled edge provided cover strip 6 can be seen. This is in cooperation with the undercut 10A torparallel pivotal and covers the entire Section width, the hinge receiving groove in the illustrated Torschließlage.

In the embodiment of Fig. 2A, a peculiarity is that the material folds 9A, 9B and 9C are made by a continuous strip of flat material in the course of multiple folding, wherein a respective cavity is defined by the folding. This arrangement has a favorable effect on the power transmission and the durability of the fastening screws. A stiffening profile 7 made of extruded light metal or plastic is clamped within the second receiving space 3B on the one hand by the hinge strip flap 2B and on the other hand by the material fold 9A and allows the hinge-like articulation of an alternative to Fig. 1 cover strip 6. Its operation results in conjunction with Fig. 2B , From this it can be seen that the cover strip 6 in addition to an upper and lower marginal hinge and attachment area a flexurally elastic hinge zone 6A, z. B. vulcanized rubber material which allows buckling of the cover strip 6 from the extended position (Fig. 2A) in the pivot position (Fig. 2B).

From Fig. 2C it can be seen how the torstensten section panel 1 D despite the same lower section edge formation (like the other section panels) can be used as a bottom Torabschluß using a Torabschlußprofils. This using the same screw fastening zone in the lower panel edge area.

From Fig. 3, as already from Fig. 2A to 2C, a thermal separation of the outer and the inner panel surface can be seen. For this purpose, also in Fig. 5 use found thermal separating strips 11. Moreover, from Fig. 3 is an alternative to Fig. 2A stiffening profile 7 can be seen, which is screwed in the same fixing and possibly additionally by screws 7A in the panel. It can, for. B. as a over the panel width extending Stiffening web to be provided for deflection reduction in the hinge area.

In Fig. 4A / B, the peculiarities consist on the one hand in the other design of the material folds 9B and 9C, which has a multi-angled web for further reinforcement of the screw. In addition, additional fastening screws 8A are provided, which are screwed into the inner panel surface and also penetrate the material fold 9A. As a result, cantilevered stiffening profiles, as can be seen in FIG. 3 and later in FIGS. 8 and 10B, can be reinforcedly fastened for improved torque transmission.

In Fig. 5, there is a peculiarity in reinforcing pieces 12, which are inserted in the material folds 9B and 9C, to secure the fastening screws 8C and 8B increased grip.

In FIGS. 6A to 8, the peculiarities consist primarily in the use of anchor arrangements 13 for improved force introduction of the fastening screws into the section panels. The dowel assembly 13 is a permanent part of the section panel edge region and preferably consists of a formed approximately in the manner of a dovetail groove material fold 13 B, from the dowel core 13 A, z. B. a plastic injection molded part, in particular with a conical bore is held. This dowel core can also be subsequently pressed into the material fold 13 B at the desired location at the desired location. This is especially true for the embodiments of FIGS. 6A to 7. By screwing a screw then the dowel core 13A spreads while the screw tip pierces by its own force in the underlying sheet metal or other flat material. By appropriate design of the material fold, in particular as shown in FIG. 8, the dowel assembly can also be slightly compressed by screwing in the screw and thereby widened slightly, which is the The introduction of force and the engagement of the dowel arrangement in the section panel are further increased. In a similar manner, the anchor arrangements 13 according to FIG. 9A / B act, wherein here only one material fold is shown and, if necessary, a dowel core can be dispensed with.

The peculiarity of FIGS. 9A to 10B is that also the third receiving space 3D of the hinge receiving groove 3 is formed by a step 3A 'of the section panel edge area. In the step 3A ', which in the embodiment according to FIG. 10A / B is in turn reinforced with an inner material fold 9C, the fastening screw 8C of the hinge 2 is screwed in similarly as for the lower hinge strap 2B. Such a design of the hinge receiving groove is particularly suitable when mounting screws are used with countersunk heads or a survival of the screw heads beyond the inner door leaf surface is not critical.
