Description

The invention relates to an assembly set, an arrangement and a method for assembling a fall protection structure on a frame at an opening in an anchor base.

In order to fasten a window in an opening, the procedure is typically as follows: The window frame is brought to the correct height and leveled from below using spacer blocks. Then spacer blocks are placed on the sides of the frame to align the slope of the window (perpendicular to the floor, for example). Screws are then placed in the opening on the side. The window can then be sealed.

In certain circumstances it may be desirable to place a fall arrest system in front of a window or door to protect a person from falling out of the window or door.

DE 10 2020 003 776 A1 discloses an arrangement with a fastening device for fastening a fall protection device to hollow chamber profiles of window or door frames that are used in the openings provided for this purpose in a building wall. Such an arrangement is equipped with a fastening device. The fastening device is characterized in that the support profiles assigned to the fall protection are arranged in the window overlap of the hollow chamber profile, in which the height and the axial position are offset from one another, on the one hand at least one attachment point and on the other hand at least two load transfer points are arranged in such a way that in the /at the fastening point(s) of the support profiles, threaded fastening holes running perpendicular to the surface of the hollow chamber profile are arranged, in which fastening screws are arranged, which protrude through through holes arranged in the hollow chamber profile in the area of the window overhang, and by means of which the respective fastening element of the fall protection is fastened to the supporting profile, and that fastening components are fixed in position in the load transfer points in the supporting profile, which are rigidly connected to the building wall are. According to

DE 10 2020 003 776 A1 fastening components are fixed in position on one of the respective fastening strips in receiving bores of a respective support profile, with each fastening strip together with the associated fastening component being rigidly connected to the housing wall.

However, installing fall protection can be traditionally inflexible and therefore difficult to retrofit and lead to a high structure that can collide with a roller shutter system, for example.

It is an object of the present invention to enable a fall protection device to be installed reliably, flexibly, and in a simple manner.

This object is solved by the subject matter according to the independent patent claims. Preferred configurations result from the dependent patent claims.

According to one embodiment of the present invention, a mounting set is provided for mounting a fall protection structure, which has a first fastening device, on a frame on or in an opening in an anchoring base, the mounting set having a fastening body that has a second fastening device for fastening to the first fastening device by means of at least a first fastening element and a third fastening device for fastening the frame by means of at least one second fastening element, which has at least one first fastening element, the at least one second fastening element, and at least one frame fastener, which is designed to fasten the frame to the anchoring base without the frame fastener being connected directly to the fastening body in the assembled state is.

According to another embodiment, an arrangement is provided which has a frame, an anchoring base with an opening to which the frame is attached, and at least one assembly set with the features described above, in which the third attachment device of the attachment body is attached to the frame by means of the at least a second fastener, and wherein the at least one frame fastener secures the frame to the anchor base without the frame fastener being directly connected to the fastener body.

According to yet another embodiment of the present invention, a method for mounting a fall protection structure on a frame on or in an opening in an anchoring base, in particular by means of a mounting set with the features described above, is provided, wherein the method involves fastening a first fastening device of the fall protection structure to a second fastening device of a fastening body by means of at least one first fastening element, fastening of a third fastening device of the fastening body to the frame by means of at least one second fastening element, and fastening of the frame to the anchorage base by means of at least one frame fastener in such a way that the frame fastener is not directly connected to it in the mounted state is connected to the attachment body.

In the context of this application, the term "assembly set" can be understood in particular as a set of several components (in particular comprising a fastening body, a frame fastener and fastening elements for fastening by means of fastening devices) that are used to mount a frame on an anchoring base and to mount a fall protection structure (the may form part of the mounting kit) are formed on the frame to be functionally cooperating. Multiple mounting kits can also be used to mount a frame and fall protection structure to the anchor base.

In the context of this application, the term "fall protection structure" can be understood in particular as a protective structure that can be attached in front of a frame - and in particular in front of a window or a door that is assigned to the frame - to prevent a person from falling from a to stop buildings. For example, if a person is in danger of falling through the opening in the anchoring base and through the frame of a building with the door or window open, the fall protection structure mounted in front of the frame can protect the person from falling even if the person crashes into the fall protection structure. For example, a fall protection structure can be designed as a glass wall or as a railing with vertical and/or horizontal struts.

In the context of this application, the term "frame" can be understood in particular as a component that is rigid at least in sections and completely or partially circumferential and can be used on or in a receiving cavity delimited by an opening inner surface in an anchoring base (such as a wall). Examples of such frames are window frames or door frames.

In the context of this application, the term "anchor base" can be understood in particular as a structural body in which an opening for attaching a frame can be formed. Such an anchor base can in particular be or have a wall, more particularly a vertical wall. Materials for such an anchoring base are, in particular, wood or wooden building materials, or else concrete and masonry building materials, metal or plastic. Furthermore, such an anchoring base can also be any composite material made from several different material components. The base material may be voided or solid (i.e. free of voids).

In the context of this application, the term "opening in the anchorage base" can be understood in particular as a (for example rectangular) through-hole in the anchorage base. Such an opening can be, for example, a window opening or a door opening.

In the context of this application, the term "fastening device" can be understood in particular to mean a mechanical structure (in particular a body and/or a recess, such as a through hole, in a body) which is used for fastening in cooperation with an associated fastening element (e.g a screw (possibly in combination with a dowel), a nail, a rivet, etc.).

In the context of this application, the term "frame fastener" can be understood in particular to mean a device that can be designed to fasten a frame to an anchoring base. For example, a frame fastener can be a frame fastening screw (for example an AMO screw from Würth), which can be screwed into the anchorage through the frame and into the anchorage, particularly in combination with a dowel. However, it can be Such a frame fixing screw can also be a bolt or screw (e.g. a concrete screw) which is set into the base material without an anchor (e.g. using a chemical anchor).

In the context of this application, the term "fastening the frame to the anchoring base without the frame fastener being directly connected to the fastening body in the assembled state" can be understood to mean in particular that in the assembled state there is no direct physical contact and no form fit between the frame fastener and the Fastening body consists. In particular, a direct structural coupling between the frame fastener and the fastening body can be dispensed with. Only an indirect and mutually contact-free force coupling between the frame fastener and the fastening body can be made possible in such a way that the frame fastener can be connected to the frame (preferably with a metal profile inside the frame) and the anchoring base in a first position and the fastening body can be connected in another, second position connected to the frame (preferably at another location to the metal profile inside the frame) such that the fastener body and the frame are force coupled together only indirectly via the frame without having a direct physical connection to each other.

According to an exemplary embodiment of the invention, a mounting set for mounting a frame on or in an opening in an anchoring base is created, in which a fall protection structure can be fastened to the frame by means of a fastening body. In addition, at least one frame fastener can be provided in the assembly set, which connects the frame to an anchoring base. Threatens a person, for example, with an open window or an open door falling from a building, the fall protection structure attached to the frame and indirectly attached to the anchor base can restrain such a person even if the person impacts the fall protection structure with a significant impact force. Advantageously, a direct physical assembly connection between the frame fastener and the fastening body can be made impossible when the fall protection structure is assembled by means of the assembly set on the frame and the anchoring base. In other words, the assembly set can be configured such that the fastening body and the frame fastener can only be assembled separately from each other due to their structural configurations, and cannot be assembled to each other. For example, a merely indirect force coupling between the frame fastener and the fastening body can be achieved by the frame fastener being fastened to a first position on the frame by assembly steps that are independent of one another and the fastening body being fastened to the frame in a different, second position independently of this, as a result of which the frame fastened to the base material ensures reliable fastening of both the frame fastener and the fastener body. However, since the frame fastener and the fastening body are free of a direct mechanical connection with one another, it is possible to subsequently install the fastening body and with it a fall protection structure on a frame that has already been mounted on the anchoring base by means of a frame fastener (e.g. when plastering work has already been completed). . The assembly set is therefore also suitable for retrofitting an already assembled frame with a fall protection structure, without any restrictions in terms of reliability or operational safety. Thus, using a mounting set according to an exemplary embodiment of the invention, a subsequent installation of a fall protection structure can be made possible in a flexible manner and at the same time a high reliability can be ensured. Of course, it is also possible to assemble the fall protection structure in a joint assembly process with the assembly of the frame on the anchoring structure.

Additional exemplary embodiments of the assembly set, the arrangement and the method are described below.

According to a preferred exemplary embodiment, the at least one frame fastener and the at least one fastening body can be designed to be force-coupled to one another in the mounted state only indirectly via the frame, in particular via a shared metal profile of the frame. Correspondingly, in the method, only an indirect force coupling of the at least one frame fastener to the at least one fastening body can take place via the frame, in particular via a metal profile of the frame. The frame fastener can preferably be placed in the anchoring base through a metal profile inside the frame, for example using a corresponding frame fastening screw. In this way, a reliable connection of the frame to the anchor base can be ensured. When the same rigid metal profile (or other component of the frame) is used to anchor the fastener body to the frame elsewhere using the at least one second fastener, the fastener body is indirectly power coupled to the frame fastener anchored in the base material via the metal profile. As a result, the fastening body and consequently a fall protection structure attached thereto are also reliably fastened to the anchoring base, thereby enabling high-strength fall protection. The described double attachment to the metal profile of the frame guarantees a particularly robust attachment, whereas in other embodiments also one Double attachment of fastener body and frame fastener can be done on other components of the frame.

According to an exemplary embodiment, the assembly set can have a plurality of frame fasteners which are designed to fasten the frame to the anchor base. For example, two frame fasteners can be provided on both the left and right side for fastening the frame to the anchoring base, with at least one further frame fastener also being provided on the underside and/or upper side.

According to one exemplary embodiment, several attachment bodies are also possible in order to achieve a particularly robust attachment of the fall protection structure. In particular, a fall protection structure can be attached to two opposite sides by means of a plurality of attachment bodies.

In the assembled state, none of the frame fasteners is preferably connected directly to the fastening body or bodies. In other words, all of the frame fasteners may only be force coupled to the fastener body or bodies indirectly, via the frame. According to this exemplary embodiment, none of the frame fasteners can have a direct physical connection (in particular a positive connection) to a fastening body for fastening the fall protection structure. This favors the flexible retrofitting of a fall protection structure while at the same time reliably anchoring the frame at several positions on the anchoring base.

According to one embodiment, the at least one frame fastener can be used as at least one fastening screw (in particular in combination with a mechanical dowel), as at least one fastening bolt (at least partially threaded and/or unthreaded). (Especially in combination with a chemical anchor) and/or be designed as at least one fastening rail. A fastening screw can be designed, for example, as an AMO fastening screw from the Würth company. This can be used in combination with a mechanical dowel, for example. It is also possible to use a fixing bolt in combination with a chemical anchor. A mounting rail can be designed in particular as a console corresponding to a window mounting system from Würth with item number 047973337, which allows a console to be mounted in front of a wall on a structure with an insulating material layer. More generally, such a fastening rail can have a console profile for placing on the anchoring base, at least one through-opening in the console profile for setting a fastening screw in the anchoring base, and a frame fastening screw attached to the console profile for fastening the frame. Furthermore, such a mounting rail can have an attachment that can be attached to the bracket profile.

According to an exemplary embodiment, the fall protection structure can have a wall, in particular a glass wall. Alternatively, the fall protection structure can have interconnected struts, for example a railing with a plurality of vertically and/or horizontally extending struts. All embodiments of a fall protection structure may be designed to protect a person from falling through the opening in the base to which the frame (and preferably a window or door) is mounted in the event of a person impacting.

According to one exemplary embodiment, the fall protection structure can have a fastening lug, in particular a metal lug, which is attached to the wall or to the struts, in particular glued, and which has the first fastening device. Preferably two Mounting brackets may be attached to opposite sides of the wall or railing structure, preferably running vertically. Such a fastening strap can in particular be a strip or a plate which is attached to the wall or a railing structure of the fall protection structure. As a result, the assembly set can be designed to be extremely compact in a direction orthogonal to the fall protection structure or a frame plane, or a particularly low structure can be achieved. This has the particular advantage that, in the installed state, components of the installation set are protected from an unwanted mechanical collision with a roller shutter (in particular a roller shutter guide rail) or the like optionally mounted on the frame and/or the anchoring base.

According to an exemplary embodiment, the first fastening device can have at least one through hole in the fall protection structure. Preferably, both the first fastening device in the fall protection structure and the second fastening device in the fastening body are each designed as a through hole, so that a fastening screw or the like as the first fastening element only has to be passed through the two through holes. This allows for easy assembly.

According to a preferred exemplary embodiment, the fastening body can be designed as a folded body. Such a fold body can in particular refer to a body with a fold, i.e. a shoulder, an edge or a fold. Such a folded body can also form a joint, a groove or a chamfer. For example, to form a folded body, the edge of a metal sheet can be flanged by 90° to form a standing seam.

According to a preferred embodiment, the fastening body can be an angle piece, in particular a metal angle piece. Such an angle which is preferably designed with an L-profile, is a particularly simple mechanical configuration of the fastening body, which also promotes a high degree of compactness and thus a low construction of the assembly set. In particular, such an angle piece can advantageously be designed as a metal plate bent at right angles, in which only through-holes need to be made for passing through the respective first or second fastening element. A first plate section of such a bent metal plate can then be placed flat on a fastening strap of the fall protection structure and fastened thereto. A second plate section of such a bent metal plate can be placed flat on the frame and attached thereto.

Preferably, the second fastening means can be attached to a strip of the elbow which corresponds to the short side of the L-profile. Correspondingly, the third fastening device can be attached to a strip of the angle piece which corresponds to the long side of the L-profile. As a result, account can be taken of the fact that due to the transverse forces acting in the event of a person impacting, the third fastening device is subjected to a greater load than the second fastening device, which is essentially protected from transverse forces. In order to be able to reliably absorb transverse forces that occur, more second fastening elements can be provided than first fastening elements, and sufficient space is then made available on the long side of the L profile for their accommodation.

According to other exemplary embodiments, the fastening body can be designed, for example, as a C profile or U profile or as a profile with a rectangular and in particular square cross section, for example if additional rigidity is desired.

According to an exemplary embodiment, the second fastening device can have at least one through hole in the fastening body. In particular, a single through-hole in the (or in the respective) fastening body can be sufficient as the second fastening device in order to effect fastening to the fall protection structure by means of a single first fastening element. This can be sufficient since the extension direction of the first fastening element is oriented parallel to the impact force when a person impacts the fall protection structure, as a result of which practically no transverse forces act on the first fastening element.

According to one exemplary embodiment, the second fastening device can have at least one reinforcing structure which annularly surrounds the at least one through-hole. In this way, the connection between the fall protection structure and the frame can be made particularly reliable and robust by means of the fastening body.

According to an exemplary embodiment, the third fastening device can have at least one through-hole in the fastening body, in particular a row of through-holes. A plurality of through-holes are preferably provided in the (or in the respective) fastening body as the third fastening device, for example two, three, four or more. If the extension direction of second fastening elements is directed perpendicularly to an impact force of a person on the fall protection structure, transverse forces can act on the second fastening elements. In order to ensure reliable protection of the person from falling even in the event of the highest impact forces, several second fastening elements can be provided.

According to an exemplary embodiment, the at least one first fastening element can have at least one metric screw. Such a metric screw can be externally threaded. The first fastening device and/or the second fastening device can preferably be equipped with a corresponding internal thread. It is also advantageous to locally thicken the fastening body in the area where the metric screw passes through, in order to create an internal thread over a larger spatial area inside the fastening body and thereby guide the metric screw particularly reliably.

According to one exemplary embodiment, the at least one second fastening element can have at least one self-tapping screw, in particular at least one self-tapping screw without pre-drilling in a metal profile of the frame. Screws can be used as self-drilling screws, which can cut both a thread and a hole themselves while being screwed in, specifically in the frame. For this purpose, the self-drilling screws can be equipped with a tip with two drill bits. The attachment body and the frame can be permanently connected with high mechanical stability using self-drilling screws. The self-drilling screws can preferably be passed through prefabricated through-holes in the fastening body and then drilled into the frame in order to ensure reliable guidance of the self-drilling screws.

According to an exemplary embodiment, the at least one frame fastener can have at least one bracket profile for passing through at least one frame fastening screw for fastening the at least one frame fastener to the frame. Further, the at least one frame fastener may include at least one reinforcing sleeve adapted for insertion into the frame and receiving an end portion of the at least one frame fastening screw is formed. Such a reinforcement sleeve, designed for example as a sleeve nut, can rest, for example, on at least one additional web of the frame and thus activate such a web to additionally support the frame fastener. Such a reinforcement sleeve can thus be used to take on loads. Tests have shown that considerable load advantages can be generated in this way.

According to one embodiment, the at least one frame attachment bolt and the at least one reinforcement sleeve may be configured for insertion into opposing side openings in the frame so as to be engaged with each other by the insertion. A user places the console on one side of the frame and inserts the frame mounting screw through the console and into the frame. From an opposite other side of the frame, the user inserts the reinforcement sleeve into the frame, causing a tip of the frame attachment screw to enter a hollow receiving chamber of the reinforcement sleeve.

According to one exemplary embodiment, the at least one frame fastening screw can be designed with an external thread and the at least one reinforcement sleeve can be designed with an internal thread that corresponds to the external thread. The frame fastening screw and the reinforcement sleeve can thus be screwed together in order to form a particularly reliable connection.

According to an exemplary embodiment, the anchoring base can be formed at least partially from a load-bearing material, in particular masonry. The connection between the frame and the anchor base using at least one frame fastener should be made in the load-bearing material.

In particular, if the frame fastener has a profile bracket, it is also possible to anchor the frame fastener in a load-bearing material of the anchoring base and to let the profile bracket extend like a cantilever into non-load-bearing material (e.g. a layer of insulating material) of the anchoring base, so that the frame can also be mounted above non-supporting material.

According to one exemplary embodiment, a metal profile of the frame can be fastened to the anchoring base by means of the at least one frame fastener in the assembled state. In addition, the same metal profile of the frame can advantageously be fastened to the fastening body by means of the at least one second fastening element. In addition, the first fastening device of the fall protection structure can be fastened to the second fastening device of the fastening body by means of the at least one first fastening element. Thus, the fastening body and consequently the fall protection structure can be fastened to the anchoring base with high strength by means of the metal profile.

Identical or similar components in different figures are provided with the same reference numbers.

Before exemplary embodiments are described with reference to the figures, some basic considerations should be summarized, on the basis of which exemplary embodiments of the invention were derived.

In order to absorb impact loads of, for example, 2.8 kN per attachment point, appropriate frame fasteners can be provided if a fall protection structure is to be mounted on a door or window frame. Conventionally, this leads to complex statics of the individual links of the entire power transmission chain (including attachment points, frame and fall protection structure) when a fastening body of a fall protection structure is mounted on a frame fastener. For this reason, among other things, conventional mounting sets for mounting a fall protection structure are usually only supported with test certificates, not with official approval. Furthermore, conventional approaches are often associated with a high build-up on a window frame. This makes it difficult to install a roller shutter and the like. In addition, it is conventionally only possible with extreme effort, a Fall protection structure to be retrofitted to an already assembled frame.

According to an exemplary embodiment of the invention, for (for example subsequent) mounting of a fall protection structure on a frame mounted on an opening of an anchor base, a rigid attachment body can be fastened on the one hand to the fall protection structure and on the other hand to the frame. For example, a glass pane can be mounted as a fall protection structure in front of a window or a door made of glass in an outside wall of a house, which (when the window or door is open) prevents a person from falling out of the building, for example from the first floor. It is particularly advantageous, on the one hand, to force-couple a frame fastener for fastening the frame to the anchoring base and, on the other hand, to force-couple the fastening body only indirectly via the frame (preferably via a metal profile inside the frame), but by means of direct physical contact or a direct physical contact or a positive-locking connection between the frame fastener and the fastener body. This ensures that the frame fastener and the fastener body can be mounted completely independently of each other. This in turn makes it possible to attach a fall protection structure to a frame that has already been installed (and, for example, already plastered) or to retrofit a frame that has already been installed with such a fall protection structure. In addition, exemplary embodiments of the invention offer significant approval-related advantages over conventional approaches, which applies in particular to high-precision applications.

The fastening body can preferably be designed as a folded body, which can advantageously be designed as an L-profile with fastening holes. This allows for a particularly compact configuration and promotes a low Construction. It is particularly advantageous to attach such a folded body to a flat attachment strap of the fall protection structure. A particularly low structure can then be achieved, with which any collision with a roller shutter or a roller shutter guide rail on the frame can be avoided.

In accordance with an exemplary embodiment of the invention, a window rebate assembly system is provided for accommodating a fall protection structure (particularly a site) to provide a fall protection system. Preferably, the fall protection structure is designed as a glass railing that is bonded to a metal strap or attached in some other way. Such a system can advantageously be retrofitted. In addition, a bonded glass railing only applies minimally to a window frame. This does not affect the function of a roller shutter or a roller shutter guide rail. In addition to the possibility of retrofitting, exemplary embodiments of the invention also enable a narrow and space-saving design.

According to an embodiment of the invention, a window attachment can be planned, for example using frame fasteners, in particular window fasteners, such as frame attachment screws (e.g. AMO screws from Würth) or a console profile (e.g. a window mounting system from Würth with the item number 047973337). . The position and spacing of the individual frame fasteners can be based on the static design. The position and spacing of fastening bodies, preferably designed as window rebate plates (to which a railing or the like is fastened as a fall protection structure) can also be defined on the basis of a static design. The bonded glass railing or other fall protection structure can be customized and adapted to a be delivered to the construction site. The glass railing can be installed using a window rebate plate as a fastening element. For this purpose, a fall protection structure designed as a glass railing, for example, is connected via a hole and a metric screw as the first fastening element. The fastening body, which is designed in particular as a window rebate plate, can then be screwed to a metal core of the frame (in particular a window frame) using self-drilling screws (as second fastening elements). The introduction of force into the anchoring base can be carried out indirectly via the metal core of the frame and the existing frame fasteners (particularly window fasteners). The window fastener can be selected individually. The number of window fold plates on each side can preferably be at least two. Such a system has legal advantages. Furthermore, a corresponding assembly set with a fall protection structure can be retrofitted without fearing a loss of function of an optional roller shutter.

figure 1 shows an arrangement 126 with a mounting set 100 according to an exemplary embodiment of the invention. More precisely shows figure 1 two cross-sections of a frame 104 mounted on an anchor base 108 in a plan view corresponding to two different vertical heights. For example, the top view represents according to figure 5 a cross-sectional view below that of FIG figure 5 lower view. The upper of the two representations according to figure 1 12 also shows that a fall protection structure 102 is mounted to the frame 104. FIG. According to figure 1 the anchoring base 108 (in the exemplary embodiment shown, a vertical wall in which an opening 140 is made as a window opening), the frame 104 (for example a window frame, from which in figure 1 only a vertical portion is shown) and the fall protection structure 102 (e.g., a glass wall extending from a bottom portion of the opening 140 in vertical direction extends only over part of the opening 140) perpendicular to the plane of the paper.

In particular shows figure 1 an arrangement 126, which is formed from the frame 104, the anchoring base 108 with its opening 140 and a mounting set 100 together with a fall protection structure 102.

The frame 104 is attached to or in the opening 140 . More specifically, the frame 104 is mounted to a boundary surface 106 of the anchor base 108 defined by the opening 140 . The anchoring base 108 is at least partially formed from a load-bearing material (masonry in the exemplary embodiment shown), but can also have non-load-bearing material (such as a layer of insulating material). The frame 104 is anchored to the anchoring base 108 in load-bearing material of the anchoring base 108. To be more precise, the frame 104 is attached to the anchoring base 108 by means of a frame fastener 122, which is implemented as a fastening screw in the exemplary embodiment shown (see illustration below according to figure 1 ). It is advantageously possible to provide a plurality of frame fasteners 122 for fastening the frame 104 to the base material 108 in order to increase the reliability of the frame fastening. As in figure 1 is shown, a rigid and vertically adjustable metal profile 128 is fastened to the anchoring base 108 in an inner region of the frame 104 by means of the frame fastener 122, in that the frame fastener 122, which is designed as a frame fastening screw, is set through the frame 104 and the metal profile 128 into the anchoring base 108 . More precisely, inside the frame 104 designed as a window frame, there is the metal profile 128 with a C-shaped, U-shaped, rectangular or even square cross-section and forms a particularly stable fastening base for the Passing through the fastening screw of the frame fastener 122 into the anchoring base 108.

The according figure 1 The upper illustration shows further components of the mounting set 100 for mounting the fall protection structure 102 on the frame 104 and indirectly on the anchor base 108.

The fall protection structure 102 has a first fastening device 110 in the form of a through hole. The fall protection structure 102 is according to figure 1 be attached to the frame 104 at or in the opening 140 of the anchor base 108, to which the first attachment device 110 contributes.

Furthermore, the mounting set 100 has a fastening body 112 which is essentially L-shaped in a cross-sectional view or a side view. To put it more precisely, the fastening body 112 has two plate-shaped legs or strips which are bent at 90° to one another. For example, such a fixing body 112 can be formed by bending a metal plate.

The fastening body 112 has a second fastening device 114 designed as a through hole in the short of the two strips for fastening to the first fastening device 110 also designed as a through hole by means of a first fastening element 116 in the form of a metric screw. The through hole in the fastening body 112 that forms the second fastening device 114 can have an internal thread that can be screwed to an external thread of the metric screw. In order to be able to form this internal thread over a particularly large spatial area (in particular over several turns), the fastening body 112 can be in the area of the second Fastening device 114 have a locally thickened section 142. A metal tab 124 of the fall protection structure 102 can be attached to the attachment body 112 by screwing the first attachment element 116 through the through-holes in the form of the first attachment device 110 and the second attachment device 114 .

Furthermore, the fastening body 112 contains in the long of the two strips a third fastening device 118 for fastening to the frame 104 by means of second fastening elements 120. The third fastening device 118 is designed as an arrangement of through holes (or alternatively blind holes) in the longer strip of the fastening body 112, im illustrated embodiment as three spaced through holes. A respective drilling screw can be passed through each of these holes as a respective second fastening element 120 and drilled into the metal profile 128 of the frame 104 . Each of the self-drilling screws can be screwed into the metal profile 128 without pre-drilling and in a thread-cutting manner. By screwing the second fastening elements 120 through the through-holes in the form of the third fastening device 118 and by screwing the second fastening elements 120 into the frame 104, the fastening body 112 can be fastened to the frame 104, more precisely to the metal profile 128 of the frame 104.

Now referring to the figure below figure 1 the frame fastener 122, designed here as a frame fastening screw, fastens the frame 104 to the anchoring base 108 by screwing the frame fastener 122 through the frame 104 and in particular through the metal profile 128 of the frame 104 and screwing it into the anchoring base 108.

Although this in figure 1 is not shown, the frame mounting screw can be screwed into a dowel in a drilled hole in the anchoring base 108 . Alternatively, the For example, a frame fastening screw designed as a concrete screw or as a threaded rod can be anchored in the anchoring base 108 by means of a chemical anchor.

As already mentioned, the two representations of figure 1 to different vertical positions of the frame 104. In other words, the attachment body 112 is attached to the frame 104 at a different position than the attachment of the frame 104 to the anchor base 108 by means of the frame fastener 122. This means that when the components of the assembly set are assembled 100, the frame fastener 122 is not directly connected to the fastener body 112. In other words, there is no direct touching contact and no direct connecting contact and no form fit between the frame fastener 122 and the fastening body 112. The fastening body 112 and the frame fastener 122 are designed in such a way that direct disassembly from one another is not possible. Instead, the frame fastener 122 is force-coupled to the fastening body 112 in the assembled state shown only indirectly via the frame 104 , more precisely via the metal profile 128 of the frame 104 . This has advantages: An opening 140 in an anchoring base 108 that is equipped with a frame 104 that has already been installed (and already plastered, for example) can easily be retrofitted with a fall protection structure 102 due to the described fastening decoupling between frame fastener 122 and fastening body 112, since this is independent of a fall protection structure 102 can be retrofitted to an already installed frame fastener 122. This can be done in that the fall protection structure 102 can be mounted on the frame 104 by means of a fastening body 112 and thereby necessarily indirectly—by means of the frame fastener 122 that has already been set—on the anchoring base 108 . This retrofit is therefore carried out without any impairment the reliability of the fall protection, since the metal profile 124 of the frame 104 provides an extremely resistant and load-resistant force coupling with the anchoring base 108 and can withstand even the highest forces.

Referring again to the illustration above figure 1 For example, the fall protection structure 102 can have a wall 172 embodied, for example, as a glass wall, to which a fastening lug 124, preferably made of metal, is glued to an adhesive surface 170. The through hole that forms the first fastening device 110 can be formed in this metal tab. The fall protection structure 102 in FIG figure 1 extremely compact in the vertical direction. Advantageously, such a fall protection structure 102 with a low thickness or low construction does not in any way collide with an optional roller shutter structure if a window made of glass is attached to the frame 104 designed as a window frame, for example, which window can be selectively closed by means of a roller shutter.

Highly advantageous in the embodiment according to figure 1 is also that the fastening body 112 is designed as a lightweight and compact metal seam body. To put it more precisely, the fastening body 112 is designed as a metal angle piece in which only through-holes for forming the second fastening device 114 and the third fastening device 118 are formed. Since such a fastening body 112 merely provides a fastening between the frame 104 and fall protection structure 102, the fastening body 112 can be designed to be extremely compact in all spatial directions. In particular, such a fastening body 112 embodied as a metallic L-profile acts synergistically with the fastening lug 124 of the fall protection structure 102 embodied as a strip-shaped plate body, in order to low construction (in particular for the free installation of a roller shutter).

To assemble the arrangement 126 according to figure 1 First, the frame 104 can be fastened to the anchor base 108, specifically using one or preferably more frame fasteners 122, which are placed through the frame 104—and preferably through the metal profile 128 of the frame 104—and into the anchor base 108. One or more attachment bodies 112 can then be attached to the fall protection structure 102, for which purpose one or more first attachment elements 116 can be used. The one or more fastening bodies 112 can then be fastened to the frame 104 at a position different from the position of the frame fasteners 122 by inserting one or preferably more second fastening elements 120 through the fastening body or bodies 112 into the frame 104, and preferably into the Metal profile 128 of the same to be set. The introduction of force from the fall protection structure 102 via the fastening body 112 into the anchoring base 108 takes place indirectly via the metal profile 128 which is anchored to the anchoring base 108 at another point by means of the frame fastener or fasteners 122 . Clearly, the fall protection structure 102 is attached to the frame 104 via the metal profile 128 or a metal rail in the frame 104 for dissipating an impact load of a person on the fall protection structure 102 and/or for absorbing wind loads.

Figure 2 to Figure 6 show different views of an arrangement 126 with a mounting set 100 according to another exemplary embodiment of the invention. figure 2 12 shows a partially exploded view of the components of the assembly 126 of anchor base 108, a perimeter frame 104 in an opening 140 in the anchoring base 108 and various components of the assembly set 100. These components include, in particular, a fall protection structure 102 with a glass wall and two perforated fastening straps 124 fastened (in particular glued) to it, a plurality of fastening bodies 112 designed as a metal L-profile, a plurality of associated first fastening elements 116 and a plurality of second fastening elements 120. The assembly set 100 also includes a plurality of frame fasteners 122, which are embodied here as frame fastening screws. figure 3 12 shows a cross-sectional view of assembly 126 in an assembled state in a vertical position with frame fasteners 126 inserted through frame 104 into anchor base 108. FIG. figure 4 shows an enlarged detail of figure 3 . figure 5 shows an enlarged detail of figure 2 after installation in a opposite figure 2 back view. figure 6 12 shows a top view of assembly 126 of FIG figure 2 after assembly is complete.

In particular, based on Figure 2 to Figure 6 It can be seen that the assembly kit 100 includes a plurality of frame fasteners 122, each configured to attach the frame 104 to the anchor base 108 at a respective location. Each of the plurality of attachment bodies 112 connects the fall protection structure 102 to the frame 104 at an associated location. None of the frame fasteners 122 are directly connected to any of the attachment bodies 112 when assembled. The assembly positions of the frame fasteners 122 on the frame 104 are thus spatially decoupled from other assembly positions of the fastening bodies 112 on the frame 104 . However, there is an indirect transmission of force from the fall protection structure 102 via the attachment body 112 and the frame 104 as well as the frame fasteners 122 to the anchoring base 108.

For example, to fully assemble a frame 104 and window 154 to a window opening (see opening 140) of base material 108, For example, at least two assembly sets 100 can be attached to the underside, at least two further assembly sets 100 to the left and at least two further assembly sets 100 to the right, with the assembly sets 100 being used together to assemble a fall protection structure 102. The top of such mounting sets 100 can remain free, for example, if a roller shutter is to be attached to the top. Otherwise, at least one assembly set 100 can also be attached to the top.

According to the view figure 4 Both a head of the frame fastener 122 designed as a frame fastening screw and a head of a second fastening element 120 designed as a drilling screw can be seen in the fastening body 112, the fastening body 112 being mounted spatially separately from the frame fastener 122. Due to the flat or low arrangement of the fastening strap 124, a roller shutter guide rail (not shown) can be attached without any problems, since the glass pane is arranged approximately in the plane of the frame.

Figure 7 to Figure 12 12 show different views of a mounting set 100 according to yet another exemplary embodiment of the invention. In particular shows figure 12 a detail of the representation of figure 7 12 to show the structure of the fastener body 112 and the frame fastener 122 in more detail.

As best in figure 12 As can be seen, each frame fastener 122 embodied as a fastening rail has a bracket profile 160 for placement on the anchoring base 108 . One or more through-openings can be formed in the bracket profile 160 in order to receive a fastening screw 162 to be set into the anchor base 108 (optionally by means of a mechanical or chemical anchor). Furthermore, a frame fastening screw 164 for fastening the frame 104 is provided on the console profile 160 . Furthermore, such a fastening rail can have an attachment part 166 embodied here as a double fastening profile, which can be fastened to the console profile 160 .

However, the embodiment differs according to Figure 13 to Figure 19 according to the embodiment Figure 7 to Figure 12 in that according to Figure 13 to Figure 19 additional measures are taken to further stabilize the attachment.

For this purpose, according to the assembly set 100 Figure 13 to Figure 19 the second fastening device 114 is provided with a reinforcing structure 190 which annularly surrounds the associated through-hole. This is best in figure 18 and figure 19 to recognize. Will this be in? Figure 13 to Figure 19 second fastener 116, not shown, is inserted into said through hole to attach the fastener body 112 to a fall arrest structure 102 via the frame 104, the ring reinforcement around the through hole stabilizes this attachment. Before the second fastener 116 in the reinforced through hole of the Fastener body 112 is inserted, this through hole is aligned with respect to a corresponding insertion hole 184 in the frame 104.

In the exemplary embodiment according to FIG Figure 13 to Figure 19 In addition, the following measure has been proven: As best in figure 15 , figure 18 and figure 19 As can be seen, the respective frame fastener 122 has a bracket profile 160 for passing through a respective frame fastening screw 164 . This serves to fasten the frame fastener 122 to the frame 104. Advantageously, a reinforcement sleeve 180 is provided for each bracket profile 160, which is designed to be inserted into the frame 104 and to receive an end section of an associated frame fastening screw 164. The frame mounting bolt 164 and its associated reinforcement sleeve 180 are inserted into opposite side openings in the frame 104 to thereby be engaged with one another. As best in figure 15 As can be seen, the frame fastening screw 164 is equipped with an external thread and the associated reinforcement sleeve 180 is equipped with an internal thread corresponding to this external thread. For assembly, the frame fastening screw 164 is inserted through a through hole in the bracket profile 160 and through a through hole in an attachment 166 and into an insertion hole in the frame 104 . The reinforcing sleeve 180 is inserted into an insertion hole 182 in the frame 104 from an opposite side of the frame 104 . Inside frame 104, the opposite end portions of frame mounting screw 164 and reinforcing sleeve 180 meet, which are then secured together by bolting them together. figure 13 FIG. 12 also shows that the add-on part 166 has through holes 186 for receiving additional fastening screws 188. FIG.

The reinforcing sleeve 180 advantageously acts as a sleeve nut in order to activate a second web of the frame 104, which is designed here as a window metal core (see Fig figure 15 , figure 18 and figure 19 ). Thus, the reinforcement sleeve 180 contributes to the absorption of loads. Tests on this have shown that considerable load advantages can be generated as a result.
