Abstract

The panel of a sectional door consists of interlinked flat sections (1) which have transverse, integrated hinge and reinforcement profiles running parallel with the swivel axes and possessing continuous ridges molded on them. The ridges are hooked into each other in pairs for forming a lengthwise hinge which is continuous over the entire length. Each section consists of a single metal sheet which, on each lengthwise side, is bent over to form an outward protruding double-layered folded lug, with inter-hooking hooks (13,14).

Description

The invention relates to a door leaf of a ceiling or side sectional door or rotary gates, especially for car garages or for halls, made of articulated flat sections, the parallel to the swivel axes, transversal integrated hinge and stiffening profiles with molded continuous beads, which to form a continuous over the entire length Longitudinal hinge are hooked into each other in pairs and for Can be disassembled. Each box profile has at least one that is approximately normal to the surface of the door leaf Stiffener on. Furthermore, at or near the End faces in the hinge area of the bearing housing sections for the admission of the journal from laterally protruding Guide elements attached with which the sections in Running rails are guided.

The door leaf of a sectional door for a private car garage usually consists of four to five sections with one Height from about 30 to 50 cm. The sections of a door leaf for Industrial halls or truck garages can also be higher, around 60 up to 70 cm. Such sections differ basically of roller shutter slats for roller shutters or roll armor for doors, shop windows or garages, which are usually only one height from 4 to 8 cm, rarely above. On their longitudinal edges the shutter slats have complementary hook-like longitudinal profiles, which are pushed together from the front. The Joints allow mutual pivoting around the longitudinal axis when winding up and unwinding the roller shutter or roller shutter.

The sections are in about 90% of the door leaves for sectional doors hinged together by means of individual hinges. Continuous longitudinal hinges are less common to find extruded aluminum profiles. These profiles are manufactured in different widths and lengths. she are never an integral part of the sections. they always will screwed to the separate frame of the sections that then with metal sheets or with wooden profile bars or wooden panels be occupied. They cause further bracing the partially large door leaf exposed to wind loads as well a better seal between the sections.

For the production of the well-known single-walled or double-walled, if necessary, foamed sections afterwards complex profiling systems or rolling mills are required, order from a flat sheet of metal or from a coil developed sheet metal strip sections with stiffeners produce, which then following the profiling first hinges screwed on and seals attached Need to become.

The invention has for its object a door leaf type mentioned so that the sections not with hinges to be installed one below the other must be connected and on a modern press brake rationally manufactured without clamping cables with only two tools can be.

To achieve this object, the invention provides that each Section consists of a single sheet of metal attached to each Long side to a double-layer protruding outwards Folded flag is bent, and that the folded flags to be continuous complementary articulated hooks folded and hooked together are.

For each section there is preferably a cross-section of a folded flag Z-shaped with two parallel to the section surface Cross legs and one connecting them, at an angle to connecting section to each section surface Articulated hook formed, and the free end cross leg has a beveled towards the connecting web narrow edge. The other double-layered flag is in the Cross-section hook-shaped to a complementary joint hook formed, compared to the cross-section in the Z-shaped bending fold two areas running parallel to its cross leg as well as a parallel to its connecting bridge in its Has wide extending area.

An embodiment is preferred in which the distance from the Articulated hook closed box profiles are formed. To is expediently on each longitudinal edge of the sheet wide edge strip of the metal sheet folded over and at a distance from the folded edge formed in the folded edge strips (Folded flag) an open box profile with protruding free edge strips for installation, fastening and closing of the box profile is formed on the inner area of the metal sheet. The outer sections are between the box profiles and folded the outer folded edges to the hinge hook. The section with the box profiles and the articulated hooks is in one piece.

Two further trainings of closed box profiles between the hook joints result from the subclaims 5 and 6. Here is a single large box profile between formed the hook joints, which are filled with foam, especially foamed, or only with insulation material, especially insulation mats.

In these constructions, the folded is on each longitudinal edge Sheet of metal formed a double-layered folded flag that is formed into a hook joint by folding or pressing. Each According to the model, the outer hook joint connects inwards a whole box, half a box or - if you don't on a box - just a flat surface, in which there are still patterns (Profiling according to wooden profile bars) embossed or pressed can be at. With boxless training can the outside must be provided with a wooden covering. It will the sections are double-walled, and expedient they are foamed. Can on the outside sheet metal along the long side the double-layer hook joints with Z-shaped Stiffening webs and folds must be edged and ready for inclusion a second, only folded on the long sides Metal sheet to be formed. The second sheet of metal is in the double-walled folding seams open to the outside with their inserted folds open inwards and closes the through the two Z-shaped webs formed, otherwise open half Box. The center bar can be at an angle of approximately 90 ° stand next to the two adjacent bridges.

This construction according to the invention has the advantage that Smaller companies are able to implement a modern, all security policy fulfilling sectional door not only economical, but also advanced in function and aesthetically both for car garages and in design can also be manufactured for industrial halls. The sections can on a modern press brake without clamping cables with only two Tools are manufactured efficiently. Large companies can also produce the sections on a modern form rolling mill and if necessary, the facing central webs of the hooks form their swivel radius in an arc shape.

The sections of a single-walled gate are made from one piece Sheet or sheet made. The sheet metal lanes are folded, folded and pressed in such a way that each section either one or two closed sides on both long sides Has box profiles for stabilization. If the top is flat, it can be covered with all types of wooden coverings, which are screwed on from the inside. To this Wise is a fire protection regulation (Austria) for wood-covered Goals met. Furthermore, the box profiles have the long sides of the bent hook joints, so that the Sections hinged effortlessly without screwing across Swivel axis interlocked and after screwing on the bearing piece with just one screw without risk of unhooking can be swiveled up to 70 °. This eliminates the Need to provide individual hinges that are aligned and have to be screwed on. There is no rotation via a hinge pin. Box profiles, infill panels and hook joint are in one piece - without bumps and Screws - and free of corrosion spots.

The sheet metal surfaces between the box profiles can be varied train and can by edging, ornaments and Embossments are further braced and designed. Because the hook joints have double material thickness, they also wear, in particular the middle bar, to stiffen the Sections at.

Eliminating hinges not only cuts costs for these themselves, but also the working hours for that Drilling the mounting holes and screwing on. At a Garage door with a width of approx. 2.5 m and a height of approx. 2.3 m with six sections, there are 15 two-part hinges, 90 mounting screws and corresponding holes as well screwing in and greasing and tapping in the hinge bolts. It can also be long between sections Plastic seals and pulling in are no longer necessary.

At least near the ends of the sections are in the only Articulated hooks projecting parallel to the level of the section, the is not retracted, positively engaging bearing pieces to accommodate roller or sliding element axles used and preferably secured against loosening on the box profile. The bearing pieces have below the retracted edge of the articulated hook a recess in which the outer edge of the Z-shaped articulated hook is pivotable and at one Boundary wall is present. With a locking lug of the bearing piece (see Fig. 5a) is a detachment and sliding of the other Articulated hook prevented.

The sliding elements mounted on a sliding element axis should be flat rectangular in cross section for engaging in flat, box-shaped, partly open on one broadside Slide rails are formed. The sliding elements are out Plastic with appropriate sliding properties and the Slide rails preferably made of aluminum, which in turn a corresponding sliding coating or sliding layer formation have on their profile inside. After removal the sections can be uncoupled from each other be what double security when door mounting offers. The bearing pieces for the axes of the guide or Sliding elements are designed so that they have a double function as a back-up counter for the connected sections take over in the event of an unwanted swivel over 70 °.

The use of flat, box-shaped aluminum tracks allows the easy production of transition arches from vertical to horizontal track sections because the Transition arches can be bent by hand over a wooden template can. This is the case with the commonly used ones Steel tracks for castors are not the case. Such approx 50 mm high sheet steel running tracks must be on a special machine be bent. The arches are usually warped and without great accuracy. They are difficult to align.

The sections can come in different widths and lengths pressed and folded a sheet metal strip with only two tools become. The hollow profiles closed along the long sides have a rectangular or square cross section. There the hook or knife joints do not rotate, only perform a pivoting movement in which the front edge of the one hook at the angle of the other hook on a line swiveling standing from 0 to 70 °, they never have to be lubricated become.

The closed box profiles can be used for further stabilization be foamed.

an embodiment similar to FIG. 9 with a flat sheet of metal inserted under the edge strips of the inwardly open box section and a finger protection foam molded section in the area of the joints.

In Fig. 1 are two adjacent sections 1 of a sectional door shown, by pressing from a flat sheet of metal the box profiles fold the longitudinal edge and fold produced by means of the folding steps shown in Fig. 2 has been. First, near the long edges Sheet 2 two box profiles 5 formed by pressing, such as this is shown in Fig. 2a. Edge strips remain 7. Next, the box profiles with a greater distance 5 each edge strip is bent or folded inwards, as shown in Fig. 2 b. This creates an outer Folded edge 9 and a double-layered edge strip 11, which then in a further folding step to that in FIGS. 1 and 2 complementary articulated hooks 13 and 14 shown folded or is pressed. In this area the is now completed Two-layer section. The articulated hooks are also reinforced as the area on both sides of the box profiles 5. The Edge strip 7 bears against the metal sheet 3 and can be opened here be fixed in a known manner, for. B. by gluing. Same thing applies to the outside of the box in the area of the articulated hook 13 and 14.

As can be seen in FIGS. 1a and 1b, the upper articulated hook is 13 Z-shaped in cross section. Along the outside is another edge 16 inward mirror image of the central web 15 bent over, while the front edge 17 of the lower, non-Z-shaped hinge hook 14 back here to the inside Box profile 5 points out and the edge strip 18 parallel to Sheet 3 and the projecting web 19 runs. The weird one Connecting web 20 runs in that shown in Fig. 1a Position of the two sections approximately parallel to the central web 15 of the articulated hook 13. In the shown in Fig. 1b angled position is the engagement of the front edge 17th of the lower articulated hook 14 in the outer base of the articulated hook 13 recognizable. The friction in this swivel or knife bearing is extremely low.

In the embodiment of FIGS. 3 and 4 Sections are the articulated hooks 13 and 14 in the middle of the box section 25 from this to the outside. To such a box profile to achieve, it is necessary, as can be seen from Fig. 4a is, in the edge region of the sheet 3 two open box profiles 26 to form half height by pressing and in next folding step, the folding in the middle of the web 28 between to make the adjacent half-box profiles 26 um, as shown in Fig. 4b, a to the sheet 3 and the projecting folded flag 30 symmetrical square closed To get box profile 25. In the last step then the folded flags 30 again to the hinge hook 13 and 14, p. Fig. 4c, reshaped to interlock them to be able to, as can be seen from FIGS. 3a and 3b. The Interlocking is similar to that of sections 1 according to Fig. 1. Between the closed box profiles can be parallel to these a usual longitudinal profile in the manner of wooden profile bars be provided, which is not shown.

3a is the path of movement of the inner bending edge 31 of the Z-shaped hinge hook 13 as a dashed arc 32 shown. It can be seen that the gap compared to the The central web 15 of the articulated hook 13 opens little, a risk of injury is not given by pinching and thus meets the requirements for adequate finger protection are. In the embodiment according to FIGS. 11 and 12, however another foam rubber profile strip 60 or 61 in the articulated hook 14 or 13 inserted, the corresponding channel-like Has longitudinal recesses 62 so that the mutual pivoting the sections are not disabled. You can go through through the Sidewalls of the kasteriprofile protruding lugs 63 one Cover plate 64 or protruding, fixed to the box profile, inserted into bending folds 65 open to the hook joints Material strips 66 be secured.

To loosen the interlocked sections during operation Preventing being safer are on both ends of all hinge hooks 14, as shown in FIGS. 5, 11 and 12, Bearing pieces 40 used from plastic. These consist of a largely filling the profile of the articulated hook 14 block-like plastic part and a mounting flange 42, which is fixed to the box section 25 by means of a screw 43 is. In the swivel range of the edge 16 of the Z-shaped articulated hook 13 there is a channel-shaped recess 44, which leaves the edge 16 the necessary freedom of movement. On the other hand is the lower limit, see Fig. 5a, this recess 44 laid and designed so that in the stretched 5a, the edge 16 bears flat, whereby slipping outward through a protruding nose 46 on the bearing piece 40 is prevented.

Inside the main part of the bearing piece 40 is a bearing bore 48 provided the inclusion of a roller or Sliding element axis 50 is used. Such an axis that with a console 51 accommodates a plastic sliding element 52 shown in Fig. 6. The running rail 54 is flat and box-shaped formed as shown in Fig. 6, and encloses the sliding element or the to the required extent Sliding block 52 form-fitting and leaves a very smooth running Sliding to guide the sections. Such flat, box-shaped Runners 54 can be used for design of transition arches slightly bend over wooden stencils what is more advantageous than the still predominantly used Steel upright rails for the accommodation of castors.

For particularly simple purposes and for the application of A section can also be made of wood coverings of any type and shape single-walled with double-walled edge areas to form the Design articulated hooks 13 and 14 without box profiles, like this 7, 8 and 9. Through the toppings in Form of wooden profiled boards 22 or wooden panels 23 these sections stiffened enough. Because of that on the inside located sheet metal this gate also corresponds to the Fire regulations in place in different countries. The wooden covering is screwed on from the inside.

In the embodiment according to FIG. 10, there is a single, broadly closed one Profile box 70 between the hinge hooks 13 and 14 trained. There is a special on each longitudinal edge wide edge strip of the metal sheet folded over and at a distance from the outer folded edge 9 a Z-shaped rectangular Bridge shaped by the height of the profile as shown in Fig. 10 clarifies. The free edges facing each other are folded back on itself, the dimensions and the position is chosen such that the bending folds thus formed 71, 72 are hookable to close the profile. 10, the sheet has a left next to the folds Embossing 73 from the width of the bending fold 71 on the right Half of the box profile, around this next to the bending fold 72 to be able to place the left half of the box profile so that the Bending folds can be brought into engagement. In the left Articulated hook 13 is a sliding profile 75, sh. also detailed picture, with inwardly protruding sealing bead 76, the one enables virtually noiseless pivoting of the articulated hook and helps seal between sections.

The box profile foamed with insulating foam The embodiment according to FIG. 11 differs from that according to FIG. 10 in that the formed to the Z-profile with right angles Edge strips only a short distance inwards and am Edge folded out folds 65 into which the cover plate 64 with inward facing, to the bending folds 65 complementary bending folds 67 for closing the box section is inserted. The bending folds 67 are so wide that they form the protruding nose 63, which the Foam profile strips 60 and 61 holds under tension.

Even the closed one filled with insulation mats 68 12 is initially an open box profile like that produced according to FIG. 11. But then it will closed by a closure panel 69, which after the inner edge strips with the folding seams open to the outside 65 is introduced. In the bending fold on the left in FIG 65 the material strip 66 is inserted, the side protrudes beyond the box profile. He holds it in the hook joint 13 inserted foam profile strips 60 securely fixed by placing it under tension on its upper side. The profile strip 61 for the hook joint 14 is located only between the bearing pieces 40 which at the two ends of the Hook joint 14 are provided. These bearing pieces 40 are in the left halves of Figs. 11 and 12 not shown to the profile strips 61 lying behind become visible to let. In the same way as the profile strip 60, the profile strips introduced into the adjacent hook joint 13 61 by a material strip inserted into the bending fold 65 66 be secured. With appropriate further training of the bending fold 65 of the embodiment according to FIG. 11 this strip of material 66 could also be under the bending fold 67 the cover plate 64 can be inserted into the bending fold 65.
