Abstract

The fastening system for fastening a plate (41), in particular an entire one-piece façade front, to an anchoring base (40), for example a house wall, comprises holding elements (1) and support elements (10) arranged on the anchoring base (40) and on the plate to be fastened (41) arranged anchor elements (18) and / or contact elements (19). The weight of the plate (41) is supported by the holding elements (1). For this purpose, the mushroom-like extensions (20) of the anchor elements (18) are suspended in the V-like slots (2) of the holding elements. Typically, in the lower region of the anchoring base (40) bearing elements (10) are mounted, are applied to the contact elements (19). As a result, the plate (41) everywhere the same distance from the anchoring ground (40). In the V-like slots (11) of the support elements (10) but also anchor elements (18) can be mounted. However, the combination of support element (10) and anchor element (18) does not support the weight of the plate (41), since the mushroom-like extension (20) of the anchor element (18) not on the end of the V-like slot (11) of the support element ( 10) rests. The attachment of the anchor element (18) in a support element (10) serves to secure the plate (41) against wind pressure and wind suction.

Description

The present invention relates to a device of the type specified in the preamble of claim 1 for attaching at least one plate, in particular an entire one-piece facade front, to an anchoring ground.

A fastening device for cladding panels is from the DE 10 2012 110 546 A1 known. At the plate to be fastened retaining tabs are mounted for attachment, which are locked in mounted on the anchorage bearing. The bearings consist of several components and are manufactured so that the retaining tabs fit exactly into a slot on the front, through which they must be guided to engage. In particular, if the anchoring ground is a vertical wall, depending on the weight of the panels to be fastened, it may be very difficult and expensive to hit the slots of the wall-mounted bearings with the retaining tabs attached to the panels. In particular, if the dimensions of the panels are very large, for example, if an entire one-piece façade front is to be fastened to an anchoring base, attachment with such a device can be difficult. To make matters worse, that in the in the DE 10 2012 110 546 A1 described fastening device is provided that a plate to be fastened is engaged in at least four camp. This means that when locking not only a bearing, but four bearings must be met at the same time exactly with the retaining tabs.

The object of the invention is to provide a fastening device which is as simple as possible and which allows easy mounting of plates to be fastened, even with higher weight and / or larger size of the plates.

The object is achieved by a device having the features of claim 1.

It is intended to connect the plate to be fastened and the anchoring ground via at least two anchor elements and at least two retaining elements. Both types of elements can be specified on the plate and the anchoring ground. For fixing the plate to the anchoring base, the retaining elements are fixed on the anchoring base, and the anchor elements are fixed at the same distance and in the same orientation to each other on the plate as the retaining elements on the anchoring ground. By fixing the positions of the retaining elements on the anchoring base, the positions of the anchor elements in the connected state of retaining elements and anchoring elements are clearly predefined. The holding elements each have at least one substantially V-shaped slot and are mounted on the anchoring base, that the slot has an upper and a lower end. The slot is always wider at its upper end. Advantageously, the holding elements are oriented on the anchoring ground that the longitudinal directions of the V-like slots are vertical. Further advantageously, the holding elements are shaped so that the wider, upper ends of the V-like slots are open at the top, so that the heads of the mushroom-like extensions of the anchor elements are suspended from above.

Towards their closed ends, the V-like slots taper.

The anchor elements have mushroom-like extensions. These extensions are shaped so that they fit into the V-like slots of the retaining elements and can be hung in them. The mushroom-like processes each have a head. Between the head and the beginning of the extension on the side of an anchor element is a stalk-like portion of the mushroom-like extension, which is narrower than the head. The head of the mushroom-like extension advantageously forms a circumferential projection relative to the stalk-like section. The projection does not have to be formed circumferentially. When an anchor member is suspended in a holding member, the stem-like portion of the extension rests on the lower end of the V-like slot of the holding member, and the head protrudes to the side of the holding member, which faces away from the anchor member, over the V-like slot out. Since the head is wider than the stalk-like portion of the extension, it is supported (in particular the projection of the head) at tensile load of the anchor element away from the holding element or down - for example, by the weight of the anchor plate attached to the plate - at the edge of the V-like slot from. In general, the weight force is the force that holds the connection between the anchor elements and the holding elements and thus fixes the plate to the anchoring ground.

A great advantage of the attachment according to the invention is that the anchor elements can be very easily hooked into the holding elements. This is especially true when the V-like slots are open at the top, so start at the edge of the holding elements. Thus, a plate to be suspended can be held over the V-like slots of the support members, that only the height position of the plate must be changed so that the mushroom-like extensions of the anchor elements hit the slots. This is particularly advantageous for heavy and large panels, especially if a crane is used for installation. An application example is the hanging of a whole provided with anchor elements according to the invention one-piece façade front in a provided with holding elements house wall. In such cases, it would be more difficult to mount the corresponding plate in a closed slot above, since the mushroom-like projections in this case by a movement of the plate would have to be passed in the horizontal direction through the V-like slots. In a connection system according to the prior art, in which tabs have to be inserted into precisely fitting bearings, the suspension operation is much more difficult. Here, the plate must be exactly aligned in all three spatial directions before passing through the tabs through the slots. This is not only very difficult to realize with a crane, but also when handing in lighter panels. When mounting plates in holding elements according to the invention, whose V-like slots are not open at the top, the required accuracy in the orientation of the plate is lower, as to be taken

Apertures, which are V-like slots, are larger. If the V-like slots of the holding elements according to an advantageous embodiment of the invention open at the top, the plate can be hung from above by a mere downward movement in the holding elements. In this case, it only has to be aligned in two spatial directions, since the height initially does not matter. In addition, the alignment in one of the two vertical directions is much easier, since the holding elements can be used as a stop for aligning the plate. If the slits are open at the top, it makes a relief that the V-like slits become wider towards the top and therefore represent a larger target for the mushroom-like extensions from the top.

Another advantage of the invention is that the parts needed to secure the plate to the base of the anchorage are easy to manufacture and assemble. Both holding element and anchoring element can each be integrally formed, which facilitates their mounting on the plate and the anchoring ground. Advantageously, both are essentially each formed from a plate, for example a metal plate. So that the head of the mushroom-like extension of the anchor element can protrude out of the slot of the retaining element on the side of the retaining element facing the anchoring base, a space must be provided in the assembled state between the slot of the retaining element and the anchoring base in which the head of the mushroom-like extension can fit , For this purpose, the holding element has a projection. This projection, which is open on two opposite sides, is advantageously achieved by repeated bending, in particular by rectangular angling, of a plate from which the holding element is produced. This advantageously creates a projection that is flat on its front side. This front-side plane of the projection of the holding element extends in the assembled state of the holding element parallel to the plane of a planar anchoring ground. The distance of this plane of the projection of the retaining element to the anchoring base is large enough that the head of the mushroom-like extension fits between the anchoring base and the projection. Advantageously, the two side parts of the projection parallel to each other and perpendicular to the plane of the projection. Advantageously, the plane of the projection is a rectangle. In the plane of the projection of the V-like slot is introduced. Advantageously, the longitudinal direction of the V-like slot is orthogonal the two side parts of the projection. Advantageously, the V-like slot is continued to its wider side in one of the two side parts of the projection. If the retaining element mounted on the anchoring base, that the longitudinal direction of the V-like slot is vertical and the slot is wider towards the top, with a correspondingly large continuation of the slot in the upper side part of the support member, the mushroom-like extension of the anchor member from above in the retaining element are mounted.

For attachment of the retaining element is provided that the side parts of the projection are advantageous angled once again, away from the projection, so that adjoining each of the two side panels a surface which is advantageously parallel to the projection plane. In these areas boreholes are introduced, which are provided for fastening the retaining elements on the anchoring ground with fastening means, for example with screws. Due to the V-like shape of the slots of the retaining elements, the mushroom-like extensions of the anchor elements are guided when hanging in a predefined position. With the determination of the retaining elements on the anchoring ground thus the position of the mushroom-like extensions of the anchor elements is fixed in the suspended state. The anchor elements must be set at the same distance as the distance of the holding elements on the anchoring ground and in an orientation corresponding to the orientation of the holding elements on the plate. By fixing the anchor elements on the plate so that the position of the plate is specified in relation to the anchoring reason. If certain parts of the plate, such as the openings for windows in a façade front, with certain positions of an anchoring reason, for. As the windows of a house wall match, both the retaining elements on the anchoring ground, as well as the anchor elements must be set exactly on the plate. A readjustment is not necessary with exact positioning of the holding and anchoring elements. This is a big advantage for large and heavy panels, especially for an entire one-piece façade front, since, in the case of such panels, accurate readjustment is of course very difficult. In particular, in an embodiment of the invention, in which in the suspended state of the plate to be fastened only slight play between the side parts of the recess of the Anchor member and the edges at the open sides of the plane of the projection of the retaining element, slipping of the attached plate is transversely to the longitudinal direction of the V-like slots effectively prevented.

Advantageously, the holding element is set on the anchoring reason that the longitudinal direction of the V-like slot in the holding element is vertical. In this case, the slot extends from an edge of the holding element and is wider at its edge side. By this orientation of the V-like slot of the mushroom-like extension of the anchor member when hanging due to the weight of the plate connected to the anchor element plate when hanging automatically in the predefined position, the lowest point of the V-like extension, out.

By carrying out the invention with support elements and contact elements, the number of parts to be accurately connected or exactly positioned can be reduced. If, for example, the anchoring base is a vertical wall, it is possible according to the invention to fasten the plate to be fastened with its anchoring elements only to retaining elements which are fixed in the upper region of the wall. Contact points in the lower area of the wall can be realized by support elements fixed to the wall and by contact elements fixed on the plate.

By the contact of the bearing elements on the support elements ensures that the distance between the plate to be fastened and the anchoring ground at each point of the plate is approximately the same.

In a variant of the invention, anchor elements can be used instead of the contact elements. So that the mushroom-like extensions of the anchor elements can be suspended in the support elements, the support elements have V-like slots. The V-like slots of the support members are longer than the V-like slots of the support members. With appropriate determination of all elements on the anchoring ground and the plate to be fastened, the heads of the mushroom-like extensions of the anchor elements, which cooperate with support elements, so in the support elements be mounted that the support elements do not carry the weight of the plate to be fastened, but prevent the connection of support and anchor element that the plate can be removed, for example by wind substantially from the anchoring ground, or the support elements.

An advantage of using anchor elements in combination with support elements is that both the anchor elements on the plate and the support elements on the anchoring ground do not have to be determined completely precisely. Due to the greater length of the V-like slots, and since the mushroom-like projections do not have to rest on the narrower end of the slots or should, the support elements can be set in the longitudinal direction of the slots with a certain tolerance. This facilitates the assembly of both the support and the contact elements, which can be defined as well as the support elements in the longitudinal direction of the slots of the support elements with a certain tolerance.

In the determination of holding and supporting element on the anchoring ground and anchoring elements on the plate, the distance between a holding and a support element on the anchoring ground and between two anchor elements on the plate is chosen so that the mushroom-like extension of the anchor element, with the Support element to be connected, in the mounted state of the plate does not rest on the narrower end of the V-like slot of the support element, that is not supported by this end. After attaching the anchor elements in the holding and supporting elements with a corresponding, described positioning of all elements, the assembled with the anchor elements plate is supported by the holding elements. By engaging the mushroom-like extensions of the anchor elements in the V-like slots of the support elements prevents the plate by wind pressure, which may be present between the plate and anchoring ground, or wind suction is pushed away on the anchoring base side of the plate from the anchoring ground.

To play in the suspended state between support and anchor element, in particular between the projection of the head relative to the stalk-like portion of the extension to eliminate the anchor member and the inside of the projection of the support element, a backup plate is provided. The backup plate advantageously has a substantially rectangular shape, wherein one of the two shorter sides has a U-shaped recess. The distance of the two parallel inner sides of this U-shaped recess is at least so large that a cross-sectional area of the stem-like portion of the extension of the anchor element fits in any orientation in the recess. The extension of the anchor element can be hung in the U-shaped recess of the backup plate. To eliminate the clearance between the support and anchor element, the securing plate is clamped from above between the projection of the head relative to the stem-like portion of the extension of the anchor member and the inside of the projection of the support element. The locking plate is so thick that the play can be eliminated. Here, the backup plate is inserted so that the stalk-like portion of the extension of the anchor element comes to rest in the U-shaped recess of the backup plate and the closed side of the U-shaped recess the stalk-like portion of the mushroom-like extension of the anchor element and / or the projection of the head the extension of the anchor element against the stalk-like portion of the extension touches. The stalk-like portion is therefore surrounded transversely to its longitudinal direction on three sides by the securing plate. As a result, the orientation of the support and the anchor element and thus also the orientation of the anchoring ground and the plate to each other is further stabilized. In particular, a movement of the anchor element or the plate in the longitudinal direction of the slot in the support element in the direction of the broader end of the slot (corresponding to described advantageous determination of the support and the anchor element corresponds to a movement upward) is hampered by a backup plate. It is important that the locking plate is so thick that it is clamped with appropriate pressure between the projection of the head against the stem-like portion of the extension of the anchor member and the inside of the projection of the support element. The biggest advantage of using the locking plate is that the anchor element is prevented from performing a described movement (upwards) and consequently the anchor element is also prevented from moving accordingly. When using the locking plate, the anchor element is not only by the weight of the plate and the held the plate elements in the holding element, but also by the clamped locking plate. It is important here that the further securing mechanism which the securing plate represents is generally based on a force acting transversely to the weight force. A similar situation is the attachment or suspension of a whole one-piece façade front on a vertical wall of the house.

Advantageously, the projection of the head of the mushroom-like extension of the anchor element relative to its stem-like portion is shaped so that the angle between the extension and the stem-like portion is more than 90 °. By this bevel of the projection of the mushroom-like extension, the clamping of the security plate between the projection of the mushroom-like extension of the anchor element and the inside of the projection of the support element is facilitated. At a smaller distance from the stem-like portion of the mushroom-like extension of the anchor member, the distance between the projection or head of the mushroom-like extension of the anchor member and the inside of the projection of the support element is smaller. If the security plate is pressed in the direction of the stem-like portion of the mushroom-like extension of the anchor member, it is clamped with a corresponding thickness and a correspondingly small distance between stalk-like portion of the mushroom-like extension of the anchor member and closed inside of the U-shaped recess.

In particular, when the anchoring ground extends in the vertical direction, that is, has an upper and a lower end, all bearing elements are advantageously set lower on the anchoring ground than the retaining elements. In particular, all holding elements are set at the same height on the anchoring ground and set all supporting elements at a same, lower level. As already mentioned, the use of support elements facilitates assembly, since the determination does not have to be as accurate as for the support elements. The weight of the plate to be fastened can rest only on the holding elements. If, with the exclusive use of retaining elements, all retaining elements are set too far down on the anchoring base, and consequently the anchor elements are too far down on the plate, there is the risk that the plate will tilt away from the anchoring ground and the anchor elements will be released from the retaining elements. Out For safety reasons, holding and anchor elements are therefore attached as far as possible.

To determine the holding and supporting elements on the anchoring base, slots are provided, in particular in the lower, adjoining the side parts of the projections of the holding and supporting elements surfaces. The longitudinal direction of these slots is advantageously oriented in the longitudinal direction of the V-like slots. Due to the elongated shape, a cross-sectionally round fastening element can be inserted at different points through the slot. As a result, a tolerance for the position at which the fastener is introduced on the anchoring ground given. This tolerance corresponds to the length of the slot minus the diameter of the round cross-section of the fastener. The fastener usually has a head. So that this head can not slip through the slot, but determines the holding or support elements on the anchoring reason, the opening of the slot must be reduced. This is done first by a sloping hole plate. In the inclined hole plate a pitch hole is inserted. Furthermore, the inclined hole plate comprises an angled edge into which no hole is embedded. Advantageously, the edge is angled at the same angle as the angle between the side part of the projection of the holding or supporting element and the adjoining this side part surfaces. Advantageously, this edge is angled at right angles.

The position of the inclined plate in the direction transverse to the slot can be varied. In this case, however, always lies on the angled edge of the inclined plate on the lower side part of the projection of the holding or supporting element. The difference between the point of the oblique hole farthest from the angled edge and the point of the oblique hole closest to the angled edge corresponds to the length of the oblong hole. The oblique hole extends in one direction. If the angled edge of the inclined-hole plate lies on the lower side part of the projection of the holding or supporting element, the oblique hole runs obliquely to the longitudinal direction of the oblong hole. Advantageously, the angle between the longitudinal directions of the long and the oblique hole is then more than 45 °. The distance between the two parallel to each other extending longitudinal sides of the oblique hole is advantageously slightly larger than the distance of the mutually parallel longitudinal sides of the oblong hole. Thus, it is ensured that the inclined plate can always be positioned over the slot so that the angled edge of the inclined plate rests on the lower side part of the projection of the holding or supporting element, and at the same time oblique hole and slot define an opening which is large enough that a fastening element with a round cross-sectional diameter in the size of the distance of the mutually parallel longitudinal sides of the oblong hole can be inserted through the opening. Thus, in the context of the tolerance for the position at which the fastening element is introduced on the anchoring base, that is to say over the length of the oblong hole, the oblique hole plate can always be displaced such that the projection of the support element or retaining element is formed by the angled edge of the oblique hole plate is supported. In addition to the support of this projection, the position of the fastening element is fixed more stable on the lower surface of the support element at the same time. By supporting the angled edge on the lower side part of the projection of the holding or supporting element and the distance of the oblique hole to the angled edge, a minimum distance of the fastening element to the lower side part of the projection of the holding or supporting element is fixed. The inclined-hole plate is usually fixed by the same fastening element, which serves to fix the support or support element, with the aid of a washer, which is placed on the inclined plate. At the same time, this further reduces the opening for the fastening element. Another function of the inclined hole plate is that the voltage applied to the projection of the support or holding element angled edge of the inclined hole plate supports this projection. In the case of the retaining element at least a part of the weight of the hinged plate rests on this projection. The angled edge reinforces this projection.

In Fig. 1 is shown as an example of an anchorage 40 the house wall of a house. In the upper region of the wall of the house, preferably the holding elements 1 and preferably the supporting elements 10 are fastened in the lower region of the wall of the house. The plate 41 to be fastened is in FIG. 1 a whole one-piece façade front. At the invisible back of the façade front are corresponding to the holding elements 1 anchoring elements 18 (see. Fig. 5 ) and corresponding to the support elements 10 Investment elements 19 (see. Fig. 4 ) appropriate. The façade front can be suspended via the anchor elements 18 in the holding elements 1.

The Fig. 2a shows a front view of a fixed to the anchoring base 40 holding member 1. In a projection 4 of the support member 1, a V-like slot 2 is approximately up to half of a plane 7 of the projection 4 embedded. In the Fig. 2b It can be seen that the projection 4 has two right angles from the plane 7 angled side parts 5, in turn connect to the right angles angled surfaces 6, in which slots 8 and holes 9 are provided for mounting the support member 1 on an anchoring base 40. Fig. 2c shows the continuation of the V-like slot 2 in the upper of the two side parts 5 of the projection 4. This continuation results in an opening 3 in the upper of the two side parts. 5

In the Fig. 3 a support element 10 is shown. The main difference between the holding element 1 from the Figures 2a, 2b and 2c and the support element 10 Fig. 3 is in this embodiment that the V-like slot 11 in the support member 10 is significantly longer than the V-like slot 2 in the support member 1. As the support member 1, the support member has a projection 12 with a plane 13 and side parts 14. At the side portions 14 close at right angles outwardly angled surfaces 15 with holes 17 or slots 16 at. The support element 10 can be used both in combination with a in Fig. 4a illustrated investment element 19 as well as in combination with a in Fig. 5a illustrated anchor element 18 can be used. For use in conjunction with an anchor element 18, an opening 38 is introduced into the upper of the two side parts 14 of the support element 10 by continuing the inserted into the plane 13 V-like slot 11. Through this opening 38 can from above the mushroom-like extension 20 of an in Fig. 5a anchor member 19 shown in the V-like slot 11 of the support element 10 are mounted. By attaching the mushroom-like extension 20 of an anchor member 18 in the V-like slot 11 of a support member 10 which is connected to the anchor member 18 plate 41 is additionally anchored to the anchoring base 40 and secured against lifting from the anchoring ground 41 by wind pressure and wind suction. The views of the retaining element 1 from the FIGS. 2b and 2c are analogous to the support element 10 Fig. 3 , with the difference that the V-like slot 11 of the support member 10 is continued deeper into the plane 13 than the V-like slot 2 in the plane 7 of the support member 1. For this reason, these views are for the support member 10 from Fig. 3 not shown again.

Advantageously, the holding elements 1 and the support elements 10 are mounted on the anchoring base 40 so that their V-like slots 2 and 11 have an upper and a lower end. The slots 2 and 11 are always wider at their upper ends. Advantageously, the holding elements 1 and the support elements 10 are oriented on the anchoring base 40 such that the longitudinal directions of the V-like slots 2 and 11 are vertical.

The Figures 4a, 4b and 4c show a possible embodiment of the contact element 19. In this embodiment, the contact element 19 is in the mounted state only on the support element 10. A protection against wind pressure or wind suction is not provided. By multiple right-angled bending a plate a recess 21 is formed in the contact element 19, the bottom of which is formed by a plane 22. The depression is bounded on two sides by two side parts 26 extending parallel to one another. To the side parts 26 close surfaces 27, are introduced into the holes 28. These surfaces 27 form right angles with the side parts 26 and are angled outwards, away from the plane 22 of the recess 21. The depth of the side members 26 is equal on both sides so that the surfaces 27 lie in one plane and can be secured on a planar anchoring ground 40 through the boreholes 28. The recess 21 of the contact element 19 can via the support element 10 made Fig. 3 be slipped and record the projection 12 of the support element 10 at least partially.

The Figures 5a, 5b and 5c show an embodiment of an anchor element 18. The anchor element 18 can be used both in conjunction with a in Fig. 2a shown holding element 1 as well as in conjunction with a in Fig. 3 illustrated support element 10 can be used. The anchor member 18 is the in the Figures 4a, 4b and 4c shown investment element 19 very similar. That in the Figures 5a, 5b and 5c illustrated Anchor element 18 differs from that in the Figures 4a, 4b and 4c shown contact element 19 characterized in that in the center of the bottom 22 of the recess 21 of the anchor member 18, a mushroom-like extension 20 is located. The mushroom-like extension 20 comprises a head 23 and a stem-like portion 24, which connects the mushroom-like extension 20 with the bottom 22 of the recess 21 of the anchor element 18. The head 23 of the mushroom-like extension 20 has over the stem-like portion 24 of the mushroom-like extension 20 has an oblique projection 25. The angle between this projection 25 and the stem-like portion 24 of the mushroom-like extension 20 is greater than 90 °.

So that the mushroom-like extension 20 of the anchor element 18 can be hooked from above into the V-like slot 2 of the holding element 1, the holding element 1 is fixed on the anchoring base 40 so that the opening 3 faces upwards.

The anchor member 18 is substantially formed of a plate. By multiple right-angled bending a recess 21 is formed in the anchor member 18. The bottom 22 of this opening 21, which is open on two opposite sides, forms a rectangular plane. This plane is surrounded on two sides by right angles bent, parallel to each other side parts 26. The distance between the two side parts 26 of the plane of the anchor member 18 is greater than the distance of the edges of the projection 4 of the in the Figures 2a, 2b and 2c shown retaining element 1, which are not surrounded by side parts 5. The anchor element 18 can be pushed over the retaining element 1 in such a way that the side parts 26 of the depression 21 of the anchor element 18 are oriented parallel to the open edges of the projection 4 of the retaining element 1. The mushroom-like extension 20, which extends from the bottom of the plane of the recess 21 of the anchor member 18 upwards, is fixed to the anchor member 18 that when mounting the anchor member 18 in the holding element 1, both the mushroom-like extension 20 of the anchor member 18 to the lower end of V-like slot 2 of the support member 1 can be hung in the slot 2, as well as the side portions 26 of the recess 21 of the anchor member 18 fit over the edges of the projection 4 of the support member 1, which are not limited by side parts 5. Thus, the position of the mushroom-like extension 20 of the anchor element 18 in V-like slot 2 of the support member 1 lend additional stability. A movement of the anchor member 18 in the direction of the side parts 26 of its recess 21 is possible in the hinged state of the anchor member 18 so maximum within the distances between the side members 26 of the anchor member 18 and the open edges of the projection 4 of the support member 1.

The side parts 26 of the anchor member 18 are another angled away from the recess 21 away. Thus, to each of the two side parts 26 of the recess 21 connects to a surface 27 which extends parallel to the plane of the recess 21. In these surfaces 27 bores 28 are introduced, which are provided for fastening the anchor members 18 on the plate 41 with fastening means, for example with screws. For this purpose, 41 spacers 33 are introduced between the surfaces 26 and the plate, which fill the space between the surfaces 26 and the plate 41, so that the fastening means can be introduced directly into the material of the spacers 33 and the surfaces 26 of the anchor members 18 an abutment to have.

When using the in the Figures 5a, 5b and 5c shown anchor element 18 in combination with a in the Figures 2a, 2b and 2c 1, the anchor element 18 and the holding element 1 are mounted on the plate 41 to be fastened and the anchoring base 40 so that the anchor element 18 can be suspended in the holding element 1, that the mushroom-like extension 20 on the lower end of the V-like Slot 2 of the retaining element 1 from the Figures 2a, 2b and 2c rests. In this case, the stem-like portion 24 of the mushroom-like extension 20 rests on the lower end of the inner edge of the V-like slot 2 of the retaining element 1. At the same time, the head 23 of the mushroom-like extension 20 engages in the V-like slot 2. In this case, the inclined projection 25 of the head 23 touches the inner surface of the plane 7 of the projection 4 of the retaining element 1. The weight of the plate 41 to be fastened thus rests at least in part over the mushroom-like extension 20 of the hinge hooked into the V-like slot 2 of the retaining element 1 Anchor element 18 on the holding element. 1

If the anchor element 18 from the Figures 5a, 5b and 5c however, in combination with a support element 10 Fig. 3 used, the anchor member 18 and the support member 10 are mounted on the plate 41 to be fixed and the anchoring base 40 that the anchor member 19 can be suspended in the support member 10 that the mushroom-like extension 20 on the lower end of the V-like slot 2 of the support element 10 from the Fig. 3 not lying. But as with the use of the anchor member 18 in combination with a support member 1, the oblique projection 25 of the head 23 contacts the inner surface of the plane 7 of the projection 4 of the support member 10. Thus, the weight of the plate 41 to be fastened does not rest on the support member 10 By attaching the abutment member 19 in the support member 10, the fixed plate 41 but against wind pressure and wind suction, which may occur between the fixed plate 41 and the anchoring base 40 or on the anchoring base 40 opposite side of the fixed plate 41 secured.

Advantageously, the narrower end of the slot 11 of the support member 10 is formed so that the two opposite edges of the slot 11 have about the same half of the slot length, starting from the narrow end of the slot 11, the same distance. This distance corresponds advantageously to the maximum cross-sectional width of the stem-like portion 24 of the mushroom-like extension 20 of the anchor member 18. In this way, head 23 and stalk-like portion 24 of the mushroom-like extension 20 of the anchor member 18 over a large area of the support member 10 so in the slot 11 of the support element 10 are hooked that the mushroom-like extension 20 can be solved only by a movement in the longitudinal direction of the slot 11 over a large part of the length of the slot 11 from the slot 11.

In Fig. 2a the narrower ends of the support member 1 are also designed so that the two opposite edges of the slot 2 of the support member 1 over approximately half of the slot length, starting from the narrow ends, the same distance from each other. This distance advantageously corresponds to the maximum cross-sectional width of the stalk-like sections 24 of the mushroom-like extensions 20 of the anchor elements 18.

Since the support element 10 essentially differs from the support element 1 only by its slot shape, the position of the mushroom-like extension 20 of the armature element 18 in the V-like slot 11 of the support element 10 by the right-angled bend in a connection of an anchor element 18 and a support element 10 the side members 26 of the anchor member 16 lend extra stability. A movement of the anchor member 18 in the direction of the side parts 26 of its recess 21 in the hinged state of the anchor member 18 in the support member 10 so maximum within the distances between the side members 26 of the anchor member 18 and the open edges of the projection 4 of the support member 10 is possible.

These mutually parallel inner sides 31 extend to the edge of the locking plate 29th

The Figures 7a, 7b and 7c show an attached in a support element 10 and secured with a locking plate 29 anchoring element 18. In the side views of FIGS. 7b and 7c some parts are also shown, which in reality could not be seen. In Fig. 7b It can be seen that the lateral surfaces 27 of the anchor member 18 are mounted on spacers 33. The spacers 33 are fixed on the plate 41, not shown, and serve as an abutment between the lateral surfaces 27 of the anchor member 18 and the surface of the plate to be fastened. As the Fig. 7c illustrates, the support member 10 is fixed with fasteners 36 through holes 17 and slots 16 on the anchoring ground 40, not shown. For this purpose, 17 washers 35 are applied to the holes. On the slots 16 inclined hole plates 34 are laid. On the inclined hole plates 34 washers 35 are applied. The fasteners 36 extend through both the washers 35 and the bevel plates 34. In the Fig. 7c the function of a backup plate 29 is easy to recognize. The backup plate 29 is between the head 23 of the mushroom-like extension 20 of the anchor member 18 and the anchoring base 40 facing side of the plane 13 of the projection 12 of the support element 10 is inserted. In this case, the securing plate 29 receives the handle-like portion 24 of the mushroom-like extension 20 of the anchor element 18. This stem-like portion 24 of the mushroom-like extension 20 of the anchor member 18 is surrounded by both sides of the U-shaped recess 30 of the backup plate 29 so that both the mutually parallel inner sides 31 of the U-shaped recess 30, and the closed side 32 of the U -shaped recess 30, the head 23 of the mushroom-like extension 20 of the anchor member 18 touch. More concretely, the head 23 is thereby touched on its bevelled projection 25. Thus, the locking plate 29 is clamped between the tapered projection 25 of the mushroom-like extension 20 of the anchor member 18 and the inside of the plane 13 of the projection 12 of the support element 10. At the same time a safeguard against a possible slipping out of the mushroom-like extension 20 of the anchor member 18 upwardly from the V-like slot 11 of the support element 10th

The position of the inclined plate 34 in the direction transverse to the slot 16 can be varied. Some possible positions are in Fig. 10 shown. However, it is always the angled edge 39 of the inclined hole plate 34 on the lower side part 14 of the projection 12 of the support element 10. However, the inclined hole plate 37 can also be used for fastening the retaining element 1, wherein the angled edge 39 rests on the side part 5 of the projection 4. In both cases, the inclined hole plate 34 fulfills two functions. On the one hand, the lower surface 15 or the lower surface 6 can be fixed with the fastening element 36 through the oblique hole 37 of the inclined hole plate 34 and the washer 35 on the anchoring base 40 become.
