专利说明:

The invention relates to a fall-through protection for light domes and light bands, which is mounted on a suspension strip, which is preferably mounted on a curb, below the dome glazing or the continuous glass glazing, according to the preamble of claim 1.
Such fall-through are variously known, as from EP 1748120 of the applicant and the literature mentioned therein. These devices have been proven, but especially, if not exclusively, for existing skylights and rooflights a fall protection is desired, which is simple and robust and which is inexpensive and easy to compensate for larger tolerances without much effort can be mounted.
In addition to the skylights and Lichtbändem who have a curb, as in the publication mentioned, there are still roof structures with a glass roof, as they are known from DE 10 103 049. In these, a substantially flat roof of light on the horizontal surface of a masonry or a flat gridwork is provided horizontally, attached without curb. For such designs, there is also a need for crash protectors that are cheaper and as safe as those of the prior art.
It is the object and object of the invention for skylights and rooflights, especially for those who have a curb in the broadest sense of the word to provide fall-through protection.
According to the invention, these objects are achieved by a fall-through, which has the features specified in the characterizing part of claim 1. In other words, the fall-through protection consists of a plurality of elongated grid elements, which have at least one narrow side via a fastening element, preferably in the form of a tab, with which they are attached to a suspension bar, preferably on the curb, preferably suspended. Each grid element is positively connected to at least one longitudinal side by means of a Längsfalzes, but not backlash-free, thus actually only captive, connected to the neighboring element, in total they are at least approximately in an element plane. The longitudinal folds are designed so that they allow between 3 and 30 mm, preferably between 5 and 15 mm offset of the grid elements transverse to the folding longitudinal direction, without causing a deterioration of the connection.
For small widths of the light domes / light bands thus smaller lengths of the grid elements, it is sufficient if the fasteners are provided on one side, then it is the length training of the individual elements to a few centimeters tolerance possible. For larger widths elements are used, which have on both sides of such fastening straps or other fasteners.
The assembly is carried out so that the grid is made of the individual grid elements by telescoping of their longitudinal folds and that then the assembled grid is suspended in the suspension rails of the light domes / light strips. Finally, against a lifting of the grid at the attachment tabs preferably provided for fixing lugs down below the suspension bar plastically deformed and pressed so that a positive locking is achieved.
The invention will be explained in more detail below with reference to the drawing. 1 shows a schematic top view, FIG. 2 shows a perspective view purely schematically, FIG. 3 shows a schematic cross section, FIG. 4 shows detail IV of FIG. 3, FIG. 5 shows a section parallel to the longitudinal axis of the elements by a dome all together and Fig. 6 shows the view in the direction of the arrow VI of Fig. 5, purely schematically.
Fig. 1 shows a schematic plan view of a corner of a generally designated 1 dome light, for light bands, which are always included in the following, mutatis mutandis the same applies. This has a curb 2, which has at least two opposite sides of a suspension bar 3. This bar or similar strips are already present in many essay wreaths and serve as a kind of framework for the exterior of the essay wreath, if such a bar should not be present, it can easily and simply screwed inside the existing frame or otherwise to him be attached. This is particularly possible in constructions according to DE 10 103 049, in which case the assembly is of course not on the missing curb, but on the frame or in the upper part of the masonry.
There are two such suspension rails 3 at least substantially parallel to each other at opposite edges of the top ring 2 is provided. In these suspension rails 3, the front ends 11 of the one to a flat (element level 12) lattice work inserted into each fuse elements 4 are hung, as will be described in the sequel be. The elements 4 are shown in Figs. 1 and 2 clearly visible. They consist of punched or by stretching produced in the manner of an expanded metal lattice elongated elements, in the illustrated embodiment, at both narrow ends, the Stimenden 11, have straightened fastening tabs 5, with their downwardly angled free ends in the recess or the recessed gutter of the suspension bar 3 are hung.
In the illustrated embodiment, the fastening tabs 5 are provided with a V-shaped floor plan (in plan view), so that each element 4 per fastening tab 5 two angled and stuck in the suspension bar 3 ends. In the area of each Einhängendes a Fixierflügel 6 is provided, which comes to lie partially by plastic deformation under the lower edge of the suspension bar 3 and represents a positive locking against the lifting of the fastening tab 5.
The individual elements 4 have, preferably at a standardized distance, as is clearly apparent from Fig. 1, different width to fill through suitable combination as good as any longitudinal extent of the dome light or the light band gapless. To compensate for manufacturing tolerances and for residual compensation, the elements 4 are formed as follows:
The individual elements 4 have along their longitudinal edges on the particularly well recognizable from Figs 3 and 4 embodiment: A longitudinal fold 7 is (in the assembled state) directed away from the element plane 12 obliquely downwards and at its lower end in the form of a in the Mounting situation horizontal hook 8 projecting trained. The adjacent element has a mating hook 9 and this in such a way that when, as shown, the hook 8 has the free end above its continuous leg, the mating hook 9 has the free end below its continuous leg. In this way, the apparent from Fig. 4 mounting situation can be achieved. Of course, the reverse arrangement is conceivable, in any case, the left and right edges (again, depending on the viewing direction) of the element formed differently, so that there is a necessary orientation during assembly.
The mounting situation shown in Fig. 4, which is an enlargement of the detail IV of Fig. 3, represents the two elements 4 in the narrowest possible arrangement seen in the horizontal direction: The outer end of the counter-hook 9 is located on the outer edge of the longitudinal fold 7 of the adjacent element. Further displacement of the right element towards the left element 4 (or vice versa) in the direction of the arrow N is not possible without deformation of at least one element 4.
If you now the two elements 4 away from each other in the opposite direction of the arrow N, so passes, depending on the design and possibly the tolerances, one of the free ends of the hook 8 or 9 to the bottom of the other hook, in most cases ideal case both at the same time. This is then the position of the two elements 4 to each other, in which a further removal in the opposite direction to the arrow N is no longer possible without causing a deformation of at least one of the components.
The dimensions of the hooks 8, 9 are chosen so that even with the greatest possible telescoping, as in the position shown in Fig. 4, there is no danger that when loading one or more adjacent elements 4 by a creaking object, For example, a person who falls through the dome lights, the connection between the individual adjacent elements 4 is released. This is also relatively easy to achieve because with a downward load, the hooks 8, 9 tend to move more closely together, so that the area in which four layers of Längsfalzes 7 are superimposed, is becoming wider. The determination of the sizes is with the knowledge of the assumed load and the material used, as well as the strength of the material and the size of the opening to be covered for the expert no problem.
Since most of a variety of elements 4 are arranged side by side, add up these possible shifts of each, as mentioned above 3 to 30 mm to a sufficient Gesamtjustierspiel, by which it is possible almost all openings of skylights or light bands gapless cover.
Fig. 5 shows a schematic section through a light strip or a dome light 1 with essay wreath 2 and suspension bar 3. Good to see the Einhängesituation of the illustrated element 4 in this suspension bar 3 and the plastic deformation by angled securing wing 6, through the a lifting of the elements 4 (these are indeed inseparably connected to each other) is prevented. The element plane 12 is projecting visible here, in the region of the obliquely downward Längsfalzes 7 4 holes are provided in the elements, on the one hand pass light, on the other hand reduce the weight of the fuse elements 4.
Fig. 6 shows in the direction of the arrow VI of Fig. 5, the hanging situation a little more detail, again, the security wings 6 are clearly visible.
As stated above, it is in particular in the case of skylights or light bands in which the length of the elements 4 is not very large, it is quite possible to alternately use elements that have at the front or the back of the attachment tabs 5, not but on the opposite side. In this way, it becomes easier in terms of tolerances, the length of the individual elements 4, this. Of course, in the selection of the elements of the different training of the hook and the counter hook account to take and always have the right combination of these interacting edge elements available.
In particular, in such cases, but not limited thereto, it is possible to attach the Längsfalze 7 only partially to the longitudinal edges of the elements 4, with such empty sections in between, that it is possible, after

Type of bayonet securing, elements to be connected 4 to be arranged in the longitudinal direction only offset by such a section length and then to push this length into each other. Although the connection strength between the connected elements is approximately halved, this is still sufficient in most cases. It is essential that in this embodiment, an unintentional longitudinal displacement is reliably prevented. As a material for inventive fall-through solid materials in question, if condensation water or the like is to be expected stainless steel, otherwise normal steel or galvanized steel, if the optics plays only a minor role, if not he case is come lacquered steels of all kinds and possibly reinforced plastic are used. In the latter case, increased care should be taken because of the UV resistance and in various applications because of the frequent dew and frost cycles. The same applies to the suspension bar 3 and the attachment means for this suspension bar. The longitudinal fold 7 together with hook 8 and hooks 9 preferably extends substantially over the entire length of each securing element 4. The connecting or separating adjacent elements is only by telescoping in the direction of the longitudinal axis of the elements 4 (normal to the plane in Figs. 3 and 4, thus normal to the arrow N and normal to the connection plane 10) possible. As a result, the best possible security of the connection of the elements 4 is achieved with each other. The invention is not limited to the illustrated and described embodiment, but can be modified variously. Thus, instead of the formation of fastening tabs 5, the front ends 11 of the elements 4 are screwed to the curb or attached there bar or the like, the advantage of the mounting tabs is the ease of assembly and disassembly, in the use of tools and loose parts in breezy Height can be waived, which is safety-advantageous. Thus, it is possible to screw instead of the plastic deformation to create the safety wing 6 screws that protrude accordingly on the outside of the front ends 11 and so take over the role of the safety wing, other elements are conceivable. In addition, it is also conceivable by screws, optionally self-tapping sheet metal screws, in the region of the folded ends of the mounting straps 5 make a multiple backup, such screws would then through the inside of the hanging loop, through the outside of the suspension bar 3 and then at least again through the outside of the Hanging tab enough. An even more extensive screwing is indeed conceivable because of the risk of damaging the inside of the curb 2 but not recommended. For the choice of material of the screw above applies to the element 4 said. It is also possible, after proper alignment of the individual elements to compensate for tolerances and residual gaps, these elements by screwing in the rebate area, especially in the hook / counter-hook to connect firmly together. The fold region may have different inclination to the element plane 12, to improve the absorption of kinetic energy by dissipation in deformation energy in case of emergency, an inclination between 30 and 70 ° to the element plane 12 is favorable. Furthermore, for the lateral edges, the elements 4 are connected only on one side with a neighboring element, special stiffeners or fasteners may be provided at the edge of the dome light or the light band. These may be tabs, angles and the like, or even specially designed elements themselves.
