Description

• ein Auflager zum Auflegen des Gitterrosts und
• einen Befestigungsabschnitt, welcher dazu ausgebildet ist, den Lichtschacht seitlich zu umgreifen, oder welcher dazu ausgebildet ist, in den Lichtschacht eingeschoben zu werden.

The invention relates to an attachment for holding a grate over a light shaft, comprising

• a support for laying the grid and
• a fixing portion which is adapted to laterally surround the light shaft, or which is adapted to be inserted into the light shaft.

The invention further relates to a grating, in particular as part of a light shaft arrangement. Moreover, the invention relates to a light shaft assembly with a light well and an essay and a development for producing an essay.

Light wells are often used to direct air and daylight to basement windows of buildings that are actually underground. They typically define a certain volume of air and allow through an overhead grid the incidence of daylight and the exchange of air, so that basements of buildings are not dependent solely on lighting with artificial light and can be supplied without the provision of active ventilation systems with fresh air ,

However, it has been found in practice that known light wells are often difficult to assemble, as an upper edge of the light shaft to which the grating is usually attached, should normally complete flush with a height level of a surrounding earthen dump surrounding the basement. However, this earth embankment is in typical installation situations of a light shaft in which a pit excavated and a basement wall is exposed to which the light shaft is to be attached, usually not yet determined and difficult to estimate. This is why there are always cases in which a light shaft has not been mounted at the correct height and thus elaborate reworking is necessary.

The document DE 10 2013 009 420 U1 shows an essay for a light shaft, by means of which a grate is adjustable in height. However, support elements are clamped only laterally by means of a respective screw, which leads to problems in stability, especially on the longer usual in buildings longer periods.

It is therefore an object of the invention to provide an attachment for holding a grate over a light shaft, which is a simple and reliable height compensation even after the installation of the light shaft allows. It is further an object of the invention to provide a grate as part of a light well arrangement, which is particularly advantageously used in particular with such an essay. Furthermore, it is an object of the invention to provide a light shaft arrangement with a light well and an attachment according to the invention. In addition, it is an object of the invention to provide a settlement, from which an article according to the invention can be produced.

This is inventively achieved by an essay, a light shaft arrangement and a settlement according to the respective main claims and by a grid as described below. Advantageous embodiments can be taken, for example, the respective subclaims. The content of the claims is made by express reference to the content of the description.

The invention relates to an attachment for holding a grate over a light shaft. The attachment has a support for placing the grate on. Such a support is in particular designed to determine the grating in terms of height and preferably also with respect to the horizontal position. The attachment furthermore has a fastening section, which is designed to laterally surround the light shaft, or which is designed to be inserted into the light shaft. Thus, the attachment portion allows attachment of the attachment to the light well, wherein the light well is not part of the essay, but is designed for use together with the essay.

According to the invention, provision is made for a plurality of receptacles to be formed in the attachment section, each receptacle being assigned a respective contact surface. In each of the shots is a respective support and / or attachment means for laying and / or attachable to the light well receivable, so that a plurality of heights of the grate above the light shaft is adjustable, wherein each of the bearing surfaces, which the receiving and / or fastening means receiving images are assigned to rest on the respective support and / or fasteners.

By means of the attachment according to the invention, height compensation can also be carried out easily even after installation of the light shaft on a basement wall, without the determination of the height being based solely on trapped parts. By providing support surfaces, it is rather possible to provide a support of the attachment on the support and / or attachment means, so that a lowering of the attachment is prevented by positive locking.

It should be understood that not only those heights are adjustable, in which the article rests with the bearing surfaces on the support and / or fasteners, but in principle, further heights can be adjusted, in which this is not the case and in which, for example, also a deadlock occurs. Typically, however, it is provided in the article according to the invention that even in the case of relaxation of such a deadlock, such as a nut or thumbscrew, only a small downward movement is possible and this ends at the latest when the support surface on the support and / or Fastener rests. This represents a significant improvement over the prior art also in the case of setting a height at which no support is provided.

It should be further understood that the invention also includes all embodiments described herein without the feature of Contact surface concerns. In particular, this feature can also be removed from the claims again.

According to one embodiment, the support is formed as a fold. This allows a simple design, wherein a light shaft can be placed on such a fold, so that it is fixed in terms of its height. The fold is typically also designed to fix the grate laterally, preferably circumferentially.

Alternatively, it is possible to form the support, for example, as an inwardly L-shaped protruding element, in which case, for example, a lateral fixation, which is performed at the fold by the upstanding outer part, for example by provided on the grid elements that with interacting with the support takes place. For this purpose, for example, also serve the bolt welded to the grid, which will be described below.

According to one embodiment, a number of rows each having a plurality of discrete locking positions are formed as receptacles in the attachment portion. In each latching position is preferably a respective support and / or attachment means for placing and / or attaching to the light shaft attachable.

In this case, in particular a support or fastening means or even a plurality of support or fastening means can be attached to one of the locking positions, wherein the locking position or the detent positions used for this purpose can be chosen such that a height level of the grating after placing the article on the light shaft exactly corresponds to the height level of a surrounding landfill. The formation of discrete detent positions allows in particular a simple assignment of the locking positions to a desired leveling and also allows for attaching multiple support and / or fastening means a simple attachment of all of these support and / or fasteners at the same distance to the support, so that the grid aligned horizontally after placing the essay on a light shaft is.

Support and / or fastening means typically have the function of at least ensuring that the attachment rests on the light shaft. In addition, fastening means are typically designed such that the attachment can thus also be rigidly connected to the light shaft at the same time. Support means are typically adapted to be placed on the light well, which attachment can then be rigidly connected to the light well, for example, by other means such as separately threaded screws or by gluing. It should be noted, however, that the invention is not limited to a rigid connection between the attachment and the light shaft.

According to one embodiment, the locking positions are formed as round holes in the mounting portion.

Preferably, in a number of holes, preferably in those with the same distance to the support, a respective extending transversely to the mounting portion tab attached as support and / or fastening means, wherein the tabs are designed to rest on the light shaft.

According to a development, each tab has a hole for the insertion of a screw, wherein the tabs are fastened to the light shaft by means of the screw. Thus, the tabs the essay not only in a defined relationship to Light shaft hold, but also contribute to the rigid fixation of this relationship.

The tabs are preferably mounted with a respective projection on the respective hole, wherein the projection is bolted to the mounting portion. This allows easy attachment of the tabs with the aid of tools, which is usually available on construction sites. For screwing, for example, a nut can be used, which can be actuated by means of a tool. It can also be used a wing nut, which in particular is actuated without tools.

According to one embodiment, the tabs extend inwardly from the mounting portion. This is particularly advantageous when the attachment portion of the attachment engages around the light shaft. Thus, in particular, an advantageous discharge of water running off the side of the attachment can be achieved, since it does not pass into the light well but laterally past it. According to an alternative embodiment, the tabs extend outwardly from the attachment portion.

According to one embodiment, the detent positions are formed as slots in the attachment portion.

Preferably, in a number of slots, preferably in those with identical distance to the support, a respective angle bracket attached as a support and / or attachment means. Each angle lug has a first leg and a second leg, wherein the first leg rests against the mounting portion and the second leg is designed to rest on the light shaft. This embodiment allows a particularly simple mounting of the angle tabs on the attachment portion, which in particular without assistance can be done by tool. The angle tabs are typically just plugged into the respective slots.

The first and the second leg of each angle lug are preferably arranged transversely to each other. This may in particular mean that they are arranged at right angles to each other. This allows a simple and expedient execution.

The second legs preferably extend inwards. This makes possible in particular an advantageous mounting of the attachment on a light shaft, when the attachment engages around the light shaft. This allows the advantages already mentioned above. Alternatively, however, the second legs may also extend outwardly.

According to one embodiment, each angle lug further comprises a third leg which is adjacent to the second leg opposite the first leg and extends from the second leg such that it engages around an edge of the light shaft when the second leg rests on it. This allows an advantageous fixation of the angle bracket and thus also the attachment to the light shaft, in particular a deflection of the attachment portion of the attachment is avoided to the outside.

The third leg preferably occupies an angle between 90 ° and 110 ° with respect to the second leg. Particularly preferably, it assumes an angle of 100 °. For example, it may also occupy angles in a range between 80 °, 85 °, 90 ° or 95 ° as the lower limit and 105 °, 110 °, 115 ° or 120 ° as the upper limit. The mentioned lower and upper limits can be combined with each other.

The third leg is preferably shorter than the first leg. More preferably, it is less than half as long as the first leg. This allows in particular a simple installation, wherein a jamming of the third leg is avoided.

According to one embodiment, the first leg is narrower than the second leg and / or the third leg. This can prevent slippage of the angle bracket and thus simplify the attachment.

According to one embodiment, it is provided that a number of rods extending parallel to the support are accommodated for resting on the light shaft in the latching positions. These can extend over the entire length or width of the light shaft and, accordingly, for example, be used in a much smaller light well compared to the essay.

According to one embodiment, it is provided that the receptacles are formed as parallel to the support aligned through holes, so that in each through hole a respective elongate support and / or fastening means, preferably a screw or rod, facing down for support or attachment to the light well receivable is. Thus, for example, a stepless height adjustment can be achieved, in particular by turning on a screw head or on a nut. Preference is given to a support, for example in the form of a lateral projection or a collar, provided on the support and / or fastening means, wherein the bearing surface of the receptacle rests on the respective support.

It should be noted that bearing surfaces are typically surrounded by respective upper bounding surfaces of a hole or slot, or even areas surrounding a hole can be formed. They do not necessarily have to be immediately identifiable as such.

Preferably, a grid is added in the support. Such a grate closes the essay upwards and prevents the collapse of larger objects. It can also allow you to walk on the grid or even drive on vehicles. In particular, a grid according to the invention described in this application can be used for this purpose. The grate can be considered according to an embodiment as part of the essay.

Preferably, the grate has at least one pin which extends through a respective hole in the attachment, wherein a respective securing split pin is inserted through the pin, which prevents removal of the grating from the attachment. This embodiment allows in particular a particularly simple and at the same time reliable installation of the grate on the attachment.

The latching positions are preferably arranged such that for each latching position, a number of further latching positions are assigned from other rows, which have an identical distance from the support. This allows the provision of a horizontal orientation of the grate in the usual mounted light shaft.

Preferably, the article is formed of three adjacent, arranged in plan view U-shaped plates. This allows in particular a particularly simple production, as will be described in more detail below. It also allows stable and reliable execution.

Preferably, the article has a total of four rows of locking positions. This has proven to be suitable in practice to provide a reliable support and connection between the attachment and light shaft.

The essay is formed like a frame according to a version. The article can also be U-shaped or rectangular in plan view. Such embodiments have proven to be advantageous in practice.

According to one embodiment, the attachment is designed to encompass the light shaft and has a compensation structure in order to horizontally reduce a border of the support, preferably in such a way that a grate which can be laterally fixed in the light shaft can also be laterally fixed in the support. According to an alternative embodiment, the attachment is designed to be inserted into the light shaft and has a compensation structure to expand a border of the support horizontally, and preferably such that a laterally fixable in the light shaft grid can also be fixed laterally in the support is. The terms "shrink" and "expand" relate in particular to the support in the attachment relative to a design without compensation structure. This can be achieved in particular that a grid can be used both in the support of the essay as well as in the light shaft itself, for example in a support of the light shaft. This saves variants of the grate. A lateral fixation is understood in particular to mean a horizontal fixation which largely or completely prevents a movement of the grate in the horizontal direction. Without a compensation structure, the support would typically be too large or too small for the same grate, which can also be fixed laterally in the light well.

The invention further relates to a grate, in particular as part of a light shaft arrangement according to the invention described below or as part of an article described above, wherein the grating has at least one fastening element for attachment to an attachment or to a light well. Such a grid is particularly advantageous in connection with an article of the invention or a light well arrangement according to the invention usable. By means of the fastening element, the grating can be fixed to the attachment or the light shaft or even be connected to it. This allows a particularly simple installation, because, for example, grid and attachment can be held together on the grid. It should be noted that the grid according to the invention can be used particularly advantageously together with the attachment according to the invention, in particular for producing a light shaft arrangement according to the invention.

According to one embodiment, the fastening means is a pin, preferably with a receptacle for a Sicherungssplint.

The pin can also be designed and / or designated as a bolt. The pin may be welded to the grate, but the pin may also be provided on the grate in some other way, for example by a corresponding configuration of the grate itself. The task of the pin is typically to provide a security of the grate. Another object is that the pin thereby provides laterally on the support a guide for the grating and therefore the design of the support or fold on the essay is no longer absolutely necessary.

According to one embodiment, the fastening means is a tab which has a slot or a bore. According to one In another embodiment, the fastening means is a tab which has a locking mechanism. In a slot or a hole can engage a suitable component for locking. For example, a locking mechanism may be configured to pass through a gap or bore, but can not be removed without special operation.

According to one embodiment, the locking mechanism has a number of anchors rotatable about a respective fulcrum fixed to the lug, which are preferably provided with a return mechanism to bias them to a respective rest position. This allows a simple embodiment of a locking mechanism, wherein the anchors are preferably formed, for example, by respective oblique edges so that they automatically occupy a position in which a push-through is possible when passing through a gap or a bore. The return mechanism may be formed, for example, as a spring and may advantageously ensure that the anchor are spent after insertion in a blocking position.

According to one embodiment, the tab is welded to the grid or formed by profile bending. The tab can also be formed by punching out a profile contained in the grate, in particular a frame profile of the grate. Such designs allow easy production.

The invention further relates to a light shaft arrangement. The light shaft arrangement has a light shaft, which is preferably made of concrete. The light shaft assembly further comprises an attachment according to the invention, wherein in terms of the essay on all the described embodiments and Variants can be used. The attachment is fastened to the light shaft by means of a number of support and / or fastening means, which are accommodated in respective receptacles.

By means of the light shaft arrangement according to the invention, the advantages described above of an attachment according to the invention for a light shaft arrangement can be utilized. In particular, this allows an advantageous adaptation of the height of a grate to a level of a surrounding earth embankment.

The attachment is preferably rigidly connected to the light shaft. This allows a permanent execution.

Particularly preferably, the support and / or fastening means are rigidly connected to the light shaft.

According to one embodiment, the attachment is connected to the light well by means of a releasable locking mechanism. The locking mechanism may include a slider which engages a slot or bore of the attachment. The locking mechanism is preferably mounted on the light shaft, in particular on the inside. Particularly advantageously, the locking mechanism can only be actuated from within the light shaft. Such embodiments allow in particular an advantageous lock between the light shaft and essay, which can hold burglars example. In particular, the exclusive operability from the inside can serve this purpose.

Preferably, the light shaft assembly also includes a grate, in particular a grate according to the invention, wherein all described embodiments and variants can be used. This is the collapse of larger items prevented and possibly also provided the opportunity to commit or drive.

The grate is preferably added to the support of the essay. The grating is preferably laterally fixed both from the support of the essay as well as by a further support formed in the light shaft. This allows usability of the grate both on the tower as well as directly on the light shaft. For this purpose, in particular a compensation structure already described above can be used to adapt lateral dimensions.

The invention furthermore relates to a development from which an attachment according to the invention can be produced by folding. With regard to the essay can be used on all described versions and variants. Illustrated benefits apply accordingly.

The development according to the invention enables a particularly simple production of an attachment according to the invention, such a development being easy to produce by standard methods such as cutting, pressing or punching and, in particular, also being able to be transported to the place of use in a particularly space-saving manner. The attachment can be made by simply folding on site, which can be done for example on the site on which the attachment is to be installed.

The settlement preferably has a first bending edge and a second bending edge, which extend transversely to a longitudinal extension of the development and which are arranged between respective plates of the attachment. At such bending edges, the development can preferably be folded.

According to a preferred embodiment, the development further comprises a third bending edge and a fourth bending edge, which extend parallel to a longitudinal extension of the settlement. In this case, the third bending edge and the fourth bending edge are arranged adjacent to a side of the development extending along the longitudinal direction, so that the support or the fold is created by folding the third bending edge and the fourth bending edge. This makes it possible to provide already at the settlement corresponding bending edges for forming the support or the fold, so that the support for placing the grating can be made locally at the construction site, the settlement still remains completely flat for transport. This allows a particularly easy handling.

It can also be provided several transactions, for example, two or three developments, from which together can form an inventive essay.

In the figures, the same or corresponding elements are denoted by the same reference numerals and therefore, if not appropriate, will not be described again. The disclosures contained in the entire description are mutatis mutandis to the same parts with the same reference numerals or identical component names transferable. Also, the position information selected in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to a new position analogous to the new situation. Furthermore, individual features or combinations of features from the illustrated and described different embodiments may represent for themselves, inventive or inventive solutions.

Fig. 1a shows a light shaft assembly 10 according to a first embodiment. The light shaft arrangement 10 has a light shaft 20 and an attachment 30 mounted thereon. The attachment 30 has a fastening portion 34, with which the attachment 30 is connected to the light shaft 20. On top of the tower 30 a grate 80 is further launched. The details of the light well assembly 10 described herein will be described in more detail below with reference to the other figures.

Fig. 1b shows a section of the light shaft assembly 10 of Fig. 1a in enlarged view. It can be seen that the attachment 30 has a fold 32 formed as a support on which the grid 80 rests. Below the fold 32 of the attachment portion 34 is arranged. In the mounting portion 34 a total of four rows 40 of receptacles in the form of detent positions 42 are formed, of which in Fig. 1b only a number 40 can be seen. The detent positions 42 of the row 40 are aligned horizontally to each other. Furthermore, the latching positions 42 are formed in the light shaft assembly 10 according to the first embodiment as round holes.

In one of the locking positions 42, a tab 50 is inserted, which rests on an edge 22 of the light shaft 20. As in particular in Fig. 1c can be seen further, the tab 50 has a projection 52 which is inserted through the receptacle formed as a round hole in the form of a locking position 42. On the outside, the tab 50 is screwed by means of a nut 54 with the mounting portion 34. Thus, the tab 50 is held rigidly in position. By the particular in Fig. 1b To be seen flat support of the tab 50 on the edge 22 of the light shaft 20, the article 30 is held above the light shaft 20 in position. In particular, slipping down is prevented, wherein by in Fig. 1b unseen Execution with a total of four tabs 50 of the grid 80 is held horizontally.

In each case a support surface 46 is formed in the respective latching position 42. If the attachment 30 slide down, this movement ends at the latest when the support surface 46 engages the tab 50. This significantly improves the long-term stability and also the resistance to loads acting on the grating 80 from above such as persons or vehicles.

As can be readily appreciated, the height of the grate 80 above the light well 20 can be adjusted by selecting a corresponding detent position 42 into which the tab 50 is inserted. Thus, different heights of the grate 80 above the light well 20 can be easily achieved. This makes it possible, in particular, first to mount the light shaft 20 on a wall, then to fill it with surrounding soil, and only then to adjust the height of the grate 80 above the light shaft 20 in accordance with the necessity imposed by the earth pile.

Fig. 1d shows the tab 50 in a single view. In particular, the projection 52 can be seen. Furthermore, it can be seen that the tab 50 has a through bore 56 which can be used to screw the tab 50 to the light well 20. For this purpose, only one screw would have to be inserted through the bore 56 and driven into the light shaft 20. This is not shown in the figures.

The Fig. 1e shows the essay 30 with the grating 80 in a single view. It can be seen in particular that the attachment 30 has a total of four rows 40 of locking positions, wherein in each row 40, a tab 50 is inserted. These are in the present case at the same height, so that during normal installation of the light shaft 20 of the grating 80 is aligned horizontally.

Fig. 1f shows a section of the combination of essay 30 and grid 80, which in Fig. 1e is shown. In particular, the connection between the grid 80 and the attachment 30 is shown.

In the attachment 30, a number of holes 35 are formed, through which a respective pin 82 of the grate 80 is inserted. The pin 82 is rigidly connected to the remainder of the grate 80 and may be referred to as a fastener. The pin 82 in turn a Sicherungssplint 84 is inserted, which prevents removal of the grating 80 of the attachment 30. Thus grid 80 and top 30 are reliably and permanently connected. By removing the pin 84, however, this connection is also detachable again, so that the grating 80 can in principle also be removed, for example for inspection purposes.

Fig. 1g shows a cross-sectional view of a portion of the cap 30 and the grid 80, in particular, it can be seen clearly that the top 30 above the mounting portion 34 forms the fold 32. For this purpose, the attachment 30 is bent over at a third bending edge 38 and a fourth bending edge 39, so that the grid 80 is held in the horizontal direction both by a laterally formed projection 33, which serves as a border, as well as resting on a support 36 and thus is held vertically in position. The pin 82 and the split pin 84 are also shown schematically.

It should be noted in particular that the fold 32 in the in Fig. 1g illustrated embodiment by two times bending over the two bending edges 38, 39 may be formed. This is a very simple process, which can also be done with on a construction site typically existing tool.

Fig. 1h shows a development 100, which can be used to produce an attachment 30 according to the first embodiment. The unwind 100 has a first plate 110, a second plate 112, and a third plate 114. Between the first and second plates 110, 112, a first bending edge 102 is formed. Between the second and third plates 112, 114, a second bending edge 104 is formed. In each of the first and third plates 110, 114, a row 40 of detent positions is formed. In the second plate 112, two rows 40 are formed by locking positions. All four rows 40 are formed parallel to each other as shown.

As in Fig. 1h can be seen further, the third and fourth bending edges 38, 39 adjacent to an edge and formed parallel to a longitudinal extent of the settlement 100.

By simply folding the unwinding 100 at the two first and second bending edges 102, 104, the example in Fig. 1e to be seen U-shaped form of the essay 30 easily made. By subsequent folding of the third and fourth bending edges 38, 39, the fold 32 can be formed. Thus, the attachment 30 is already made, which can be done easily with commonly available on a construction site tools. The processing 100 allows for a very simple production by means of common machining methods, and also allows a very space-saving transport to the site.

The Fig. 2a to 2d show a light shaft assembly 10 according to a second embodiment. The second embodiment is carried out similarly to the first embodiment, which is why below only the differences will be discussed.

In contrast to the first embodiment, the locking positions in the second embodiment are not formed as round holes, but as slots. The formed as slots detent positions 44 are also arranged in a row 40. The locking positions formed as slots 44 are each aligned horizontally and further parallel to each other.

Through each slot of a respective row 40, an angle bracket 60 is inserted, which has a first leg 62 and a second leg 64. The first leg 62 is flat against the attachment portion 34. The second leg 64 is aligned transversely to the first leg 62, which is particularly in Fig. 2c good to see. As in particular in Fig. 2d is good to see, the second leg 64 is wider than the first leg 62. This prevents slipping through the corresponding locking position 44th

As in Fig. 2b can be clearly seen, the second leg 64 rests on the edge 22 of the light shaft 20. Thus, it allows in a similar manner as in the first embodiment, a reliable edition of the essay 30 on the light shaft 20. Thus, ultimately, the grating 80 is held in position over the light shaft 20. By selecting a suitable slot or corresponding slots with the same distance to the grating 80, the height of the grating 80 can be set and changed over the light shaft 20 even after mounting the light shaft 20 on a wall and changed. A rigid connection can, if desired, for example, by not shown screws or other fasteners.

The attachment 30 rests with a bearing surface 46 of the locking position 44 on the angle bracket 60, which prevents slipping down. This is especially in Fig. 2c clearly visible.

The Fig. 3a to 3d show a light shaft assembly 10 according to a third embodiment. This is similar to the second embodiment executed, which is why reference is made for the most part to the description of the second embodiment. In contrast to the second embodiment, in the light shaft assembly 10 according to the third embodiment, an angle bracket 70 is provided which not only a first leg 72 and a second leg 74, but also has a third leg 76. The third leg 76 is significantly shorter than the first leg 72 and is disposed opposite to the first leg 72 on the second leg 74. For the second leg 74, the third leg 76 assumes an angle of 100 °. The details of the formation of the angle bracket 70 are particularly in the cross-sectional view of Fig. 3c and the perspective view of Fig. 3d clearly visible.

How out Fig. 3b can be seen, the third leg 76 of the angle bracket 70 surrounds the edge 72 of the light shaft 20. This fixation of the attachment portion 34 of the attachment 30 is also achieved in the horizontal direction on the light shaft 20. This can, for example, facilitate assembly and counteract bending of the attachment 30 over time.

The Fig. 4a shows an article 30 with a grid 80, which are designed as an alternative to the previously written execution of a grid 80. Along with one in this figure and the associated one Fig. 4b and 4c not shown light shaft results in a fourth embodiment of a light shaft assembly.

The grating 80 and the attachment 30 according to Fig. 4a are in particular fastened together in an alternative manner, as described below with reference to FIGS Fig. 4b and 4c is explained in more detail.

Fig. 4b shows the grid 80 in a cross-sectional view. It can be seen in particular that the grating 80 on the outside to inside, here only schematically illustrated slats 81 has a peripheral edge 83 which is formed as a stamped and bent profile. On the edge 83, a tab 85 is formed at the bottom, which is bent so that it extends transversely to the fins 81 down. In the tab 85, a slot 86 is formed. The tab 85 may be referred to as a fastener.

Fig. 4c shows the tab 85 in a perspective view. It is the area which is in Fig. 4a marked with a circle. It can be seen in particular that the tab 85 extends through a slot 35 which is formed in a support 36 of the cap 30 downwards. The slot 86 of the tab 85 is thus exposed and can be positively held by a pin, not shown, or other locking mechanism. This allows an advantageous and, in the case of a corresponding embodiment, releasable connection between the grate 80 and the support 30.

Fig. 5 shows a yet alternative embodiment of the tab 85 of the grid 80. In this case, a locking mechanism 90 at the lower end of the tab 85 is arranged. Unlike the in Fig. 4b and 4c illustrated embodiments, the tab 85 of the embodiment of Fig. 5 no slot 86 on.

The locking mechanism 90 includes a first armature 92 and a second armature 94. The first armature 92 is rotatably attached to the tab 85 about a first pivot 93. The second armature 94 is rotatably attached to the tab 85 about a second pivot 95. The two anchors 92, 94 are in particular rotatable in opposite directions to each other, as shown by the two in Fig. 5 shown parts is shown. Between the two anchors 92, 94 a return mechanism in the form of a spring 96 is formed, which the two anchors 92, 94 in the in Fig. 5 biased shown rest position. By respective bevels, the two anchors 92, 94, however, formed such that they pierce through a slot with a corresponding extent, for example, the in Fig. 4c shown slot, are rotated so that the corresponding passage is made possible. For this purpose, in particular the first armature 92 is rotated clockwise, while the second armature 94 is rotated counterclockwise. After passing through the slot, the two anchors 92, 94 again rotate in opposite directions, so that they again the in Fig. 5 take shown rest position. By each of the tab 85 laterally projecting parts of the armature 92, 94, a removal of the tab 85 is prevented in the reverse direction. For this purpose, the two anchors 92, 94 would have to be rotated manually, so that a passage through the corresponding slot is possible.

Fig. 6a shows a light shaft assembly 10 according to a fifth embodiment. In a modification of the first embodiment, the attachment 30 is not arranged outside, but inside in the light shaft 20. To set and determine the height of the tabs 50 are not inward, but outward. They are thus in the same way on the light shaft 20.

Otherwise, please refer to the above description.

Fig. 6b shows the essay 30 of FIG. 6a and the grate 80 contained therein separately.

They beads 120, 122, 124, 130, 132, 134 are formed horizontally and serve to reinforce the settlement 100 and the attachment 30 produced therefrom.

FIG. 6d shows an alternative handling 100. In contrast to the execution of Fig. 6c are the two bending edges 38, 39 formed horizontally only in the middle. Beading is not available. Furthermore, a first breakout zone 140 and a second breakaway zone 145 are provided, from which individual elements, which are shown in a rectangular shape, can be broken out and / or bent out laterally. These can, for example, additionally rest on the light shaft and thus provide additional stability. In particular, it is also possible to bend the elements of the breakaway zones 140, 145, for example in the manner of a roller shutter, and to hang them on a wall of the light shaft. Thus, an embodiment can be realized, in which a side wall of the article is located in the light shaft, while a transverse thereto side wall is located outside of the light shaft.

Fig. 6e shows a possible attachment of the grate 80 to the attachment 30. Here, a screw 150 with a screw 152nd both through the grating 80 as well as through the top 30 inserted therethrough. The grating 80 is pulled by a nut 154 to the essay 30 and secured it.

Fig. 7a shows an attachment 30 according to a sixth embodiment. This attachment 30 is formed in two parts, namely a first part 160 and a second part 170. The two parts 160, 170, when they are put together, the attachment 30, which in contrast to the previous embodiments on all four sides, ie extends in a rectangular shape in plan view.

By means of such an embodiment, in particular the depth of the attachment 30 can be adjusted by, for example, the two parts 160, 170 can be fastened together in different positional relationships.

Fig. 7b shows a development 100 for the production of the first part 160. Fig. 7c shows a processing 100 for the production of the second part 170. Regarding the details, reference is made to the above descriptions of other transactions. It should, however, be explicitly pointed out that the bending edges 38, 39 extend over three sides in the case of the first part 160, but only over one side in the case of the second part 170. Thus, the bending edges 38, 39 extend over four sides, on which ultimately also the support is formed.

Fig. 8a shows an alternative handling 100 and Fig. 8b shows another alternative processing 100. These have only two plates 110, 112 and 112, 114 respectively. For example, they may be used together to form a three-sided attachment 30.

Fig. 8c shows yet another alternative development 100 with only one plate 112, but with an additional bending edge 38a, so that a total of three bending edges 38a, 38, 39 are present. Accordingly, the fold can be formed. The bending edges 38a, 38, 39 are formed only centrally of the plate 112.
