Description

Technical field

BACKGROUND OF THE INVENTION The invention relates to a door leaf of a ceiling or side sectional door or a centered door, in particular for garages for passenger cars or halls, of articulated interlocking planar sections having parallel hinged and reinforcing profiles running parallel to the pivot axes. molded continuous bosses which are paired together for the entire length of the continuous longitudinal hinge and unhooked for disassembly. Each box profile has at least one reinforcing bar running at approximately normal to the plane of the door leaf. In addition, bearing bushes are provided on the end faces or near them in the region of the hinge of the sections for receiving the bearing journal of laterally extending guide elements, by means of which the sections are guided in the guide rails.

BACKGROUND OF THE INVENTION

The sectional door for a private car garage usually consists of four to five sections with a height of approximately 30 to 50 cm. The sections of a single door leaf for industrial halls or garages for trucks can be even higher, approximately 60 to 70 cm. Such sections are fundamentally different from roller shutter bars for roller shutters or roller armor for doors, shop windows or garages, which are usually only 4 to 8 cm high, rarely more. At their longitudinal edges, the roller shutter rods have complementary hook-shaped longitudinal profiles which are inserted into one another from the front. The joints allow relative rotation about the longitudinal axis during winding and unwinding of the roll shutter or roll armor.

With approximately 90% of sectional door gates, the individual sections are articulated together using individual hinges. Rarely, continuous longitudinal hinges of extruded aluminum profiles are used. These profiles are made in different widths and lengths. They are never a fixed part of sections. They are always screwed onto special section frames, which are then lined with metal sheets or wooden profile bars or wooden panels. They cause further reinforcement of the door leaf, which is subjected to partially high wind loads, as well as better sealing between the sections.

For the production of the known single-walled or double-walled or even subsequently foamed sections, expensive profiling devices or rolling mills are required in order to form sections with reinforcements from a straight sheet metal sheet or a strip of metal strip unwound from the coil, which are then they only have to screw in the hinges and place the seals.

The object of the invention is to provide a door leaf of the type mentioned above in such a way that the sections do not have to be connected to each other by means of individually mounted articulated hinges and can be manufactured rationally on a modern folding press without clamping stretching with only two tools.

SUMMARY OF THE INVENTION

To accomplish this, the invention contemplates that each section consists of a single sheet of metal which is bent at each longitudinal edge to a two-layer folded tongue extending outwardly, and that the folded tongues are folded and hooked into continuous complementary articulated hooks.

Advantageously, for each section, one folded tongue in a Z-shaped cross-section, with two transverse arms extending parallel to the section surface and a connecting bar, these joining, extending obliquely to the respective section surface, is formed on the articulated hook, and narrow edge, folded to the connecting bar. Another two-layer folded tongue is hook-shaped in cross-section on a complementary articulated hook which, in contrast to the bending groove, has a Z-shaped cross-section in the Z-shaped cross-section, as well as a region extending parallel to its cross bar.

One embodiment is advantageous in which the box profiles are formed at a distance from the articulated hooks. For this purpose, a wider edge strip of the metal sheet is folded on each longitudinal edge of the sheet, and an open box profile with a projecting free edge strip is provided with the free edge strip to be inserted, fixed and closed at a distance from the formed bending edge. on the inner edge of the sheet. The outer sections are folded over the articulated hooks between the box profiles and the outer bending edges. The section with box profiles and articulated hooks is one-piece.

Two further embodiments of closed box profiles between the hook joints result from the dependent claims 5 and 6. Here, a single large box profile is formed between the hook joints, which is filled with foam, in particular foamed, or just filled with insulating material, in particular an insulating insert.

In this construction, a two-layer folded tongue is formed on each longitudinal edge of the folded sheet metal sheet, which is shaped into a hook joint by folding or extrusion. Depending on the model, the entire cabinet, half cabinet, or - when dropping from the cabinet - closes inwardly on the outer hook-in joint, or just * * · · β «► ..

«• ·« · A planar surface into which a pattern can still be embossed or pressed (profiling according to wooden profile bars). In the case of a cabinet-free version, the outside can be provided with wooden paneling. A double-walled section is created and is efficiently foamed. On the outside of the sheet metal, two-layer hook joints with Z-shaped reinforcing bars and grooves can be bent from the longitudinal side and formed to receive a second, only folded second sheet of metal on the longitudinal sides. The second sheet of metal is slid into the upwardly open, double-walled groove by its inwardly opened grooves, and closes the otherwise open half-cabinet formed by the two Z-shaped partition walls. The central partition may form an angle of approximately 90 ° with the two connecting partition walls.

This design according to the invention has the advantage that even smaller companies are able to produce modern, all safety regulations meeting sectional doors, not only economically but also functionally advanced and aesthetically pleasing, both for car garages and industrial halls. The sections can be manufactured rationally on a modern folding press without clamping stretching with only two tools. Large companies can also produce sections on modern forming mills and, if necessary, arcuate to create inverted center bars of the hooks equal to their turning radius.

The sections of a single-walled door are made of one-piece sheet metal or sheet metal. The sheet metal strips are bent, folded and extruded such that each section has on either longitudinal side for stabilization optionally one or two closed box profiles. If the upper side is planar, it can be lined with wooden cladding of any kind, screwed on from the inside. This complies with the fire protection regulations, eg Austrian, for wood-paneled doors. Furthermore, the box profiles have folded hooks on the longitudinal sides so that the sections can be hinged effortlessly, without the need to work with the hinged joints. By screwing, they are hinged transversely to the pivot axis, and can be rotated up to 70 ° without screwing in the bearing part after screwing in the bearing part. This eliminates the need to locate individual hinges that need to be directed and screwed on. There is no rotary movement using the hinge pins. Box profiles, filler plates and hook joints are one-piece - without joints and screws - and without forming corrosion points.

The sheet metal surfaces between the box profiles can be varied, and can be reinforced and made with edges, ornaments and pattern. Since the hinge joints have twice the thickness of the material, they additionally contribute, in particular their central crossbar, to the reinforcement of the sections.

Removing the hinges eliminates not only the cost for the hinges themselves, but also the working time required for drilling fastening holes and screwing in. With a garage door with a width of approx. 2.5 m and a height of approx. 2.3 m with six sections, 15 two-part hinges, 90 fastening screws and the corresponding hole as well as screwing and lubricating and knocking the hinge pins are eliminated. In addition, long plastic seals and their retraction may be omitted between sections.

At least close to the end ends of the sections, shaped engaging bearing parts are mounted in the articulated hook extending only parallel to the plane of the section, which is therefore not retracted, to secure the axes of the guide rollers or sliding elements, and preferably secured to the housing profile. The bearing parts have a recess below the retracted edge of the articulated hook in which the pivotable outer edge of the Z-shaped articulated hook is adjacent to the boundary wall. By means of the securing axis of the bearing part, see Fig. 5a, the second articulated hook is prevented from slipping and sliding off.

The sliding elements mounted on the sliding axis should be of rectangular cross-section in the cross-section to engage flat, on the wider side of the partially open box-like sliding rails. The sliding elements are made of plastic with corresponding sliding properties or have a sliding layer design on their profiled inner side. After the bearing parts have been removed, the sections can be disconnected from each other, providing double the safety of the door assembly. The bearing parts for the axes of the guide or sliding elements are designed to assume the double function of securing the supporting bearings of the related sections when inadvertently rotated over 70 °.

The use of flat, box-like aluminum guide rails permits the easy production of transition curves from vertical to horizontal sections of guide rails, since the transition curves can be bent by hand using a wooden template. However, this is not possible with conventional steel guide rails for guide rollers. The approximately 50 mm high sheet steel guide rails must be bent on a special machine. The arches are usually distorted and without great accuracy. They are difficult to balance.

The sections can be extruded and folded in different widths and lengths from a sheet metal strip with only two tools. The hollow sections enclosed along the longitudinal sides have a rectangular or square cross section. Since the hook or knife joints do not perform any rotary movement in which the front side of one hook pivots at an angle of 0 to 70 ° at the other hook, they need never be lubricated.

Closed box profiles can be foamed for further stabilization.

DETAILED DESCRIPTION OF THE INVENTION

Fig. 1 shows two adjacent sectional door sections 1, which were made of a flat sheet metal by extruding the box profiles and folding the longitudinal edge, and folding using the folding steps shown in Fig. 2. two box profiles 5 as shown in Fig. 2a. Here, the edge strips 7 remain. As a next step, each edge stripe 7 is bent or folded inwardly at a greater distance from the box profiles 5, as shown in FIG. 2b. This results in an outer folding edge 9 and a two-layer edge strip 11, which is then folded or pressed into the complementary articulated hooks 13 and 14 shown in FIGS. 1 and 2 in a further folding step. The articulated hooks 13 and 14 are also reinforced, as is the area on both sides of the box profiles. The edge strip 7 abuts the sheet 3 and can be fixed therein in a known manner, for example by gluing. The same applies to the outside of the housing in the area of the articulated hooks 13 and 14.

As can be seen in Figures 1a and 1b, the upper articulated hook 13 is formed in a Z-shaped cross-section. Along the outside, the edge 16 is bent inwardly, mirror-like to the central bar 15, while the front side 17 of the lower articulated hook 14, which is not Z-shaped, is directed back inwardly toward the box profile 5, and the edge strip 18 extends parallel to the sheet 3 and the projecting bar 19. The inclined connecting bar 20 extends approximately parallel to the position of the two sections shown in FIG. 1b, the engagement of the leading edge 17 of the lower articulated hook 14 in the outer base of the articulated hook 13 is noticeable. The friction in this pivoting or knife bearing is extremely low.

In the exemplary embodiment of the sections shown in Figures 3 and 4, the articulated hooks 13 and 14 protrude outwardly in the middle of the box section 25. In order to achieve such a box section 25, it is necessary, as can be seen from FIG. 4a, to form two open box sections 26 at half height in the edge region of the sheet 3 by pressing and in the next folding step 4b, in order to maintain, as shown in FIG. 4b, a quadratic closed box profile 25 symmetrical to the sheet 3 and the outward folded tongue 30. In the last step, the folded tongues 30 are then reshaped into articulated hooks 13 and 14, see FIG. 4c, so that they can hook into each other, as shown in FIGS. 3a and 3b. The interlocking is here the same as the interlocking of the sections 1 according to FIG. 1. A conventional longitudinal profiling in the form of wooden profile bars, not shown here, can be arranged parallel to them between the closed box profiles 25.

In Fig. 3a, the movement path of the inner bending edge 31 of the Z-shaped articulated hook 13 is shown as a dashed arc 32. It can be seen that the gap relative to the central bar 15 of the articulated hook 13 opens slightly so that there is no risk of pinching injury. compliance with adequate finger protection requirements. In the embodiment according to FIGS. 11 and 12, however, a foam rubber profile strip 60 and 61, respectively, having respective channel-like longitudinal recesses 62 is inserted into the articulated hooks 14 and 13, respectively, so as not to hinder the relative rotation of the sections. They can be secured by protrusions 63 of the cover sheet 64 protruding over the side walls of the box profiles, or by means of overhanging strips 66 of material which are fixed to the box profile, inserted into the bending grooves 65 open to the hook joints.

In order to more reliably prevent the release of the interlocked sections in operation, the bearing parts 40 of plastic are inserted at both ends of all the articulated hooks 14 as shown in FIGS. 5, 11 and 12. These consist of a block-shaped plastic part, which largely fills the profile of the articulated hooks 14, and a fastening flange 42 which is fastened to the box profile 25 by means of a screw 43. In the pivoting region of the Z-shaped articulated hook edge 13 there is a channel recess 44 gives the edge 16 the necessary freedom of movement. On the other hand, the lower boundary (see FIG. 5a) of this recess 44 is sized and constructed such that, in the extended pivoting position of FIG. 5a, the rim 16 abuts flat, thereby preventing slipping outwardly by the protruding protrusion 46.

A bearing bore 48 is provided within the main portion of the bearing portion 40 to accommodate the axle 50 of the guide pulley or slide. One such axis, which supports the plastic sliding element 52 by means of a bracket 51, is shown in FIG. 6. The guide rail 54 is flat and box-like, as shown in FIG. 6, and surrounds the sliding element or slide 52 in the required volume. , and allows gliding with very smooth running to guide the sections. Such flat, box-like guide rails 54 can be easily bent to form transition arches by means of wooden stencils, which is more advantageous than the still predominantly high profile steel rails for holding guide rollers.

For particularly simple purposes and to accommodate wood cladding of any kind and shape, the section for forming the articulated hooks 13 and 14 without box profiles can also be formed with a single wall, with double-walled edge regions as shown in FIG. 7, FIG. 8 and 9. By means of cladding in the form of wooden profiled boards 22 or wooden panels 23, these sections are sufficiently reinforced. With regard to the metal plate on the inside, this door also complies with the fire protection regulations in force in different countries. The wooden cladding is screwed on from the inside.

In the embodiment of FIG. 10, a single wide closed profile box 70 is formed between the articulated hooks 13 and 14. For this purpose, a particularly wide edge strip of the sheet is folded over each longitudinal edge, and a rectangular letter-shaped crossbar is formed at a distance from the outer bending edge. The height of the profile as shown in FIG. 10. The free edges facing each other are bent back to one another, the dimensions and position being chosen in such a way that the bending grooves 71, 72 thus formed are hooked together so that the profile concluded. Referring to FIG. 10, the sheet metal to the left of the bending groove width 71 on the right half of the box profile 73 has a pattern 73 so that it can be positioned next to the bending groove 72 on the left half of the box profile in such a way that the bending grooves can be engaged. A sliding profile 75 is inserted in the left articulated hooks 13, see also detail view with a sealing bead 76 protruding inwards, which allows practically noiseless pivoting of the articulated hooks and contributes to sealing between the sections.

The insulated foamed box profile of the embodiment of FIG. 11 differs from the embodiment of FIG. 10 in that the edge strip shaped at right angles to the Z-shaped profile extends only a short piece towards the inside and has an outwardly folded folding grooves 65 into which the cover sheet 64 together with the inwardly directed folding grooves 65 are inserted by complementary folding grooves 67 to close the box profile. The bending grooves 67 are so wide that they form an outwardly projecting protrusion 63 which fixes the foam strips 60 and 61 under tension.

The closed box profile of FIG. 12, filled with the insulating insert 68, is also made as shown in FIG. 12 first as an open box profile, as in FIG. 11. This is then closed by means of a closure sheet 69 which is open bending grooves 65. placed outwardly under the edge strips extending inwards. In Fig. 12 the left bending groove 65 is inserted a material strip 66 which laterally extends over the box profile. The foam profile strip 60, placed in the hook joint 13, is securely fixed by tensioning on the upper side thereof. The profile strip 61 for the hook joint 14 is located only between the bearing parts 40, which are arranged at both ends of the hook joint 14. These bearings 11 and 12 are not shown in the left halves of Figs. In the same way as the profile strip 60, the profile strip 61 located in the adjacent hook joint 13 can be secured by a material strip 66 inserted into the bending groove 65. In another embodiment of the bending groove 65 of the embodiment of FIG. inserted under the folding groove 67 of the cover sheet 64 into the folding groove 65.
