EP2958636B1 - Fall arrester having damping, and damping elements for a fall protection device - Google Patents

Description

The invention relates to a fall arrester with damping and damping elements for a fall arrest system that can be installed without fastening means penetrating the roof structure, and to a fall arrest system that includes a number of fall arresters, each of which is connected to a fall arrester.

Fall protection and fall protection systems are designed to protect people working on roofs and other elevated areas. On roofs that are only accessed for installation and maintenance work or for the purpose of green roofs, permanent railings are usually not installed and fall protection is installed. For safety reasons, people working on a roof without railings must be secured by a rope attached to a fall protection device.

When setting up the fall protection on a flat roof, fastening means and fastening points that penetrate the roof surface and its insulation layers are preferably dispensed with. The elimination of the fastening points penetrating the roof structure has the great advantage that the individual layers of the roof structure are not affected. The installation of the fall protection does not affect the tightness of the roof. In the event of a fall, fall arrest systems should minimize the free fall distance and absorb the fall of the secured person with as little damping as possible.

Various safety devices that can be installed without penetrating the roof are known from the prior art, ie safety devices that can be installed without the use of fastening means penetrating the roof structure.

Document discloses for ballasted roofs DE 201 09 056 U1 a fall protection that can be installed without penetrating the roof, which consists of a flat support with a fabric structure (support surface) and loops attached to the support surface. The fall protection is positioned above the roof waterproofing level and weighed down by the green roof structure, with the loops for attaching the safety rope being routed upwards through the green roof structure.

The utility model HU 3070U relates to a fall arrest system with lightning protection function that can be installed without penetrating the roof. The holders of the fall protection each consist of a support surface lying in the plane and a post that is guided upwards in the vertical direction. A load bearing layer is disposed above the bearing surface of each fall arrest bracket. The load bearing layer is weighed down by a surcharge so that, depending on the weight of the surcharge, the sliding movement of the fall arrest device is made more difficult. The ballast can, for example, consist of a multi-layer green roof structure.

To achieve optimal damping, the holder consists of HU 3070U known fall protection essentially consists of a one-piece steel profile, which is initially formed into a plane lying arc with a circular or polygonal shape, the round steel before the arc is joined in a radial direction to the center point of the arc and from the center at right angles to vertical ones is guided upwards. At the upper end section, the vertical section has a fastening element for fastening a safety rope. With appropriate grounding, such a fall protection holder can also serve as a lightning protection system. This applies in particular to a fall protection system consisting of several of the holders described above, which are connected to one another by an electrically conductive wire rope.

document DE 103 33 113 A1 discloses a roof penetration-free installable fall protection, for roofs with roof ballast, which a Support surface and a post connected thereto and projecting over a surface of the support surface, the post having a fastening element for securing a fall load to be protected against falls in a section remote from the support surface and projecting over the roof load. The fall protection has a load-bearing layer intended as a base for at least part of the roof load. The load-bearing layer is connected to the bearing surface, so that a multi-layer structure is created in the area of the bearing surface. The load-bearing layer, which protrudes laterally beyond the supporting surface, is dimensioned in such a way that the fall protection against the roof load holds the fall load acting on the fastening element. The load-bearing layer can form one of the layers of the multi-layer green roof.

In order to avoid that the part of the panel remote from the fall load is not lifted from the ground or is only lifted to a limited extent, the post facing the off DE 103 33 113 A1 known fall protection belongs, not rigid, but has a joint or a spring. Alternatively, the post and the fastening element provided for fastening the safety rope can each be designed in such a way that they show a visible deformation after being subjected to the load of the fall, and thus bring about a damping load application. A fall is also cushioned by a certain displacement (see paragraph 14) of the fall arrest device in the direction of the falling load.

At the in DE 103 33 113 A1 device disclosed, the post is held by a post receiving element (cf. 6 Reference number 36) or by a thread (cf. 10 Reference numeral 30) is connected to the base plate, with the post not being stabilized by additional means in the area of its lateral surface in either of the two cases. The standing plate can have an upper and a lower part, with the load-bearing layer being arranged between the two, so that there is a multi-layer structure limited to the area of the standing plate.

The post, fastener or base to which the post is connected may be DE 103 33 113 A1 known fall protection consist of any weatherproof material that can withstand the relevant loads. The components mentioned are preferably made of metal. If the post is to be deformable, glass fiber reinforced plastic or hard rubber is proposed as the material for the post. Flat fiberglass reinforced material forming part of the load bearing layer and/or the base plate is in DE 103 33 113 A1 not revealed. In the DE 103 33 113 A1 disclosed device, or its components, also have no predetermined breaking points.

Out of DE 60 2004 010846 T2 ( = EP 1 803 871 A2 ) is known a safety device consisting of a floppy flap and two flange-like bodies. The flange-like bodies serving as the base of the device rest on the top and bottom of the slack flap serving as the ballast receiving element and thus have a multi-layered structure in the area of the base. The flange-like bodies are connected by a fastener. For attaching the safety cable, the attachment means has an eyelet at the top or is connected to a post. However, the post is not stabilized by the flange-like bodies in the area of its lateral surface. In a preferred embodiment, the two in DE 60 2004 010846 T2 disclosed flange-like body incisions and perforations, which cause a plastic deformation of the flange-like body in the event of a crash and can thereby dampen a crash. Flat fiberglass reinforced material forming part of the load bearing layer and/or the base plate is in DE 60 2004 010846 not revealed.

Other fall arrest devices that can be installed without penetrating the roof are out EP 2 279 031 B1 and WO 2007/089139 A2 as well as off US2011/0005150A1 , DE 10 2006 054 408 A1 and EP 1 690 567 A2 known.

In the case of the aforementioned fall protection systems that can be installed without penetrating the roof, a limited spatial displacement of the fall protection system in the event of a fall is permitted within the framework of the safety specifications. The limited spatial displacement can be understood as a controlled sliding movement, the sliding movement advantageously causing a cushioning of the fall and thereby advantageously reducing the stress on the individual parts as well as the stress on the safety line and the safety harness as well as the stresses acting on the falling person.

From document DE 10 2008 012 232 A1 is the use of in HU 3070U described fall protection known in connection with portable ballast elements as transportable fall protection. With this transportable fall protection, the base of the respective fall protection holder is not loaded by the bulk material belonging to the green roof, but by several ballast elements that are connected to the fall protection while the fall protection is in use, ie temporarily.

At the in DE 10 2008 012 232 A1 disclosed transportable fall protection it is provided that the section of the fall protection running in the vertical direction is at least partially surrounded by an elastic material in the area or section surrounded by the ballast elements. The material, which preferably consists of a cylindrical rubber section, causes additional cushioning in the event of a load and should prevent the cable holder from buckling at right angles in the area of the upper edge of the ballast elements. Instead, the rubber section achieves a more rounded kinking of the section of the fall arrest device running in the vertical direction. Disadvantageously, in the event of a fall, the elastic material used as kink protection, which surrounds the vertical post section of the fall protection in sections, has no damping effect worth mentioning. As with the other fall arrest devices known from the prior art, the damping of the from DE 10 2008 012 232 A1 well-known fall protection in the event of a fall simply by the deformation of the spirally curved in the area of the base Post and caused by the limited displacement (controlled sliding movement) of the entire fall protection weighted by ballast elements.

However, the previously known fall arrest systems that can be installed without penetrating the roof and are suitable for performing a controlled sliding movement have no additional measures for damping a fall apart from the respective deformable posts or cable holders.

Various technical measures for cushioning falls are already known from the technical field of fall protection that cannot be installed without penetrating the roof (i.e. fall protection that is firmly connected to the roof structure).

So reveals the document EP 2 216 466 A1 a device that is to be firmly connected to the roof and cannot be installed without penetrating the roof, in which a deformable section made of sheet steel can be integrated in the base area (cf. Fig. 22). The deformable section surrounds the upwardly projecting post in the area of its lateral surface and provides additional stabilization of the post in the event of a fall. Flat fiberglass-reinforced material that forms part of the load-bearing layer and thereby contributes to improving post anchorage and/or stabilizing the post is in EP 2 216 466 A1 not revealed.

DE 103 18 322 B3 discloses a fall protection device (anchorage point) consisting of a base plate and a post connected to it (retaining rod) with a lifting eye. The anchor point is firmly (ie not without roof penetration) connected to the roof by the base plate. The lateral surface of the post is surrounded by a plastically deformable sleeve. The sleeve ensures that the post is not already deformed by the pre-tensioning of the safety ropes and that no undesirable increase in force occurs when a person falls into the safety rope. Flat glass fiber reinforced material that forms part of the load bearing layer and thereby improves the contributes to post anchorage and/or stabilizes the post is in EP 2 216 466 A1 not revealed.

GB 2 354 052 A discloses an anchor point for a fall arrest system. Each attachment point is connected to the roof by means of a fastener (bolt) without penetrating the roof and has an elastomeric element for damping in the event of a fall, which surrounds the outer surface of the post at least in sections. Flat fiberglass-reinforced material that forms part of the load-bearing layer and thereby contributes to improving post anchorage and/or stabilizing the post is in GB 2 354 052 A not revealed. None of the above prior art documents discloses the improved dampening properties of sheet fiberglass reinforced material as part of a multi-layered post anchor fall arrest system or a fall arrest system with a post stabilizer.

In particular, none of the documents discloses a multi-layered ballast element that corresponds in structure and purpose to the fall arrester according to the invention, with at least one of the layers of the fall arrester made of a composite material reinforced with glass fibers and/or carbon fibers (GRP layer and/or CFRP layer ) consists.

Accordingly, the documents mentioned also do not disclose the technical advantages that arise when the individual layers of the multi-layer section are connected to one another at least in sections in the manner of a laminate, or when the individual layers of the multi-layer section are enclosed by an outer shell made of GRP material.

Against this background, the object of the invention is to provide additional damping elements for a cable holding device, wherein the cable holding device can be used alone or in combination with several similar cable holding devices as fall protection that can be installed without penetrating the roof and has improved damping properties having. In particular, the object of the invention is to provide additional damping elements for a cable holding device, which has at least one standing element (support surface) lying in the plane and a vertical, deformable post fastened on the upper side of the standing element, as well as providing additional damping elements in one as a post anchorage serving stand element (support surface).

The object is achieved by a multi-layer fall arrester according to claim 1, i.e. by a fall arrester which has a post anchorage and/or a post stabilizer. The object is also achieved by a post stabilizer according to the invention, which can be used as an additional damping element in combination with a conventional fall protection device, which has at least one standing element (support surface) lying in the plane and a vertical post attached to the top of the standing element.

• ein mehrschichtiger Fangschlitten mit Pfostenstabilisator, als auch
• ein mehrschichtiger Fangschlitten mit Pfostenverankerung, sowie
• ein Pfostenstabilisator

als "zusätzliches Dämpfungselement".Thus, for the purposes of the invention, both

• a multi-layer fall arrester with post stabilizer, as well
• a multi-layer fall arrester with post anchoring, as well as
• a post stabilizer

as an "additional damping element".

The core idea of the invention consists in the at least sectionally multi-layered structure of the mentioned damping elements, with at least one of the layers consisting of a composite material (GRP layer) reinforced with glass fibers and/or carbon fibers, and the individual layers of the multi-layered section among themselves at least in sections are connected to each other in a laminate-like manner or are connected to each other by an outer shell made of GRP material. In addition, the core idea is the integration of a post stabilizer and/or a post anchorage into the multi-layer section of the fall arrester, the fall arrester having the additional function of an enlarged contact surface or the function of a load-bearing layer.

With regard to the internal structure of the contact surface or the internal structure of the load-bearing layer, the previously known fall protection systems that can be installed without penetrating the roof have no measures or features that could bring about additional damping of a fall.

In contrast, the present fall arrester causes additional damping in the event of a fall due to its multi-layer structure, at least in sections, in combination with the post stabilizer integrated into the multi-layer structure of a fall arrester, or in connection with the post anchoring integrated into the multi-layer structure of a fall arrester.

The additional damping is brought about because the multi-layered sections of the additional damping elements each have different deformation properties compared to a single-layer material.

The change in the deformation properties of the fall arrester can also be varied by combining different materials (e.g. rubber, sheet metal, materials reinforced with glass fibers) inside the multi-layered fall arrester sections.

Alternatively, the change in the deformation properties of the fall arrester can be varied in that the layers are connected to one another at least in part and/or at least in sections in the manner of a laminate. A further way of connecting the layers can also be achieved by an outer covering. Materials reinforced with glass fibers (GRP materials), which can be hardened with the addition of a hardenable polymer, have proven to be particularly useful for covering or framing the multi-layer fall arrester sections with an uppermost and a lowermost layer.

The shifting of the layers inside the multi-layered sections is made more difficult by the hardened GRP shell, so that on in this way a variation of the damping properties of the multi-layered damping elements can be achieved.

Thus, the multi-layered nature of the fall arrester relates to several aspects and advantages. On the one hand, the multiple layers allow the integration of a post stabilizer and/or a post anchorage in the multi-layer section of the fall arrester. On the other hand, the multiple layers result in improved damping of the rope holding device used in combination with the fall arrester in the event of a fall, because at least the layers on the inside of the multi-layered area are arranged in such a way that they can move against one another in the event of a fall, thereby providing damping.

The other two damping elements provided according to the invention, i.e. the post stabilizer and the post anchorage, which can optionally also have a multi-layer structure, are integrated in the fall arrester, which is multi-layer at least in sections.

"Integrated" in the context of the invention means that the fall arrester, in particular the multi-layered section of the fall arrester, is connected to the post stabilizer in the area of its underside end section (base area), or that the fall arrester, in particular the multi-layered section of the fall arrester, is connected to the post anchorage connected is.

A fixed, i.e. non-detachable connection is preferred, which is produced by connecting protruding sections of the fall arrester to protruding sections of the post stabilizer or the post anchorage by gluing, laminating or by mechanical fasteners. A common layer of GRP material is particularly preferred because this material particularly improves the damping in the event of a fall.

The advantage of the invention additional damping elements as a whole is that their use in conjunction with a rope holding device consisting of post and stand element (support surface) in the event of a fall significantly improves the damping of the fall.

The post belonging to the rope holding device can be in one piece and as in HU 3070 U or in DE 10 2008 012 232 A1 revealed to merge into the spirally curved stand element. In an alternative, the item can also be in several parts and be connected to a flat plate that serves as a standing element.

Furthermore, a post that does not have a stand element can be connected by the lock nut to a post adapter that also serves as a stand element. Instead of the lock nut 2e, a thread can also be cut into the post adapter or a threaded nut can be integrated into a multi-layer post adapter made of GRP material, so that the post can be fastened to the post adapter without a lock nut.

For safety reasons, a fall arrest device must be repositioned if it has made even a slight sliding movement. As a rule, this means that the layers of the roof structure must be completely rebuilt, at least in the area of those fall protection brackets that have moved under the load of the fall. However, the effort for the partial reconstruction of a green roof is often almost as great as a complete new installation of the green roof. For cost reasons alone, it is therefore advantageous if displacement of the fall protection can be avoided.

Ideally, the use of the damping elements according to the invention can even ensure that the components belonging to the cable holding device are not displaced in relation to the roof surface in the event of a fall, ie the energy released during a fall is completely absorbed by the additional damping elements according to the invention and the deformable components of the fall arrest system (deformable post and deformable cable bracket).

In any case, the use of the damping elements according to the invention ensures that the length of the sliding movement performed by a fall arrest device equipped with one or more of the damping elements to dampen the fall energy does not exceed a distance of 1.00 m. A fall arrester equipped with one of the damping elements according to the invention, in particular a fall arrester equipped with the fall arrester according to the invention, therefore meets the requirements of the EN 795 standard.

In a preferred embodiment it is provided that, in addition to the fall arrester, the post stabilizer and/or the post anchorage are also constructed in several layers, at least in sections.

The multiple layers of the post stabilizer and/or the post anchoring additionally provided in the preferred embodiment allows the connection types between the two mentioned damping components and the fall arrester to be varied. The overlapping arrangement of the layers in combination with connecting means (adhesives) and/or technical fasteners (e.g. screws or rivets) that act over a large area between the layers, which penetrate several of the layers and thus connect them to one another, determine the stability of the respective connection over a wide range . It corresponds to the core idea of the invention that the damping properties of the fall protection device can be varied overall by varying the stability of the connection in the area of the multi-layered components.

In a particularly preferred embodiment, the multi-layer section of the fall arrester has at least one layer made of a composite material reinforced with glass fibers and/or carbon fibers, the composite layer being a common layer of the multi-layer Post stabilizer and / or the multi-layer post anchor forms.

The use of composite materials reinforced with glass fibers (GRP) and/or carbon fibers (CRP) or other suitable fibers plays an important role in the multi-layer structure of the fall arrester, the post stabilizer and the post anchorage. Materials made of fiber cement or perforated metal sheets (perforated metal sheets) can also be used, at least in sections, for the construction of the fall arrester, the post stabilizer and the post anchorage.

Composite materials made from glass fiber reinforced plastics (GRP), referred to here as GRP materials, are characterized by high strength and low weight. Curable polymers are used to strengthen the fiber mats (glass fiber fabric). The usual resins, e.g.

The strength of the GRP material can be greatly influenced solely by the arrangement of the layers within the overall multi-layered GRP material. With a consistently overlapping arrangement of the glass fiber layers, a very high level of strength is achieved. In the case of a butting arrangement of individual layers, on the other hand, the strength of the multiplicity of layers arranged butting and sometimes overlapping is reduced.

In a particularly preferred embodiment of the fall arrester, the GRP layer on the upper side of the fall arrester extends beyond the edge of the fall arrester and rests on at least part of the surface of the upper side of additional ballast receiving elements, which serve to increase the surface area of the fall arrester.

Due to the full-area, ie over the entire surface extending support of the GRP layer (which itself can be multi-layered, ie can include a large number of individual GRP layers) on the additional ballast receiving elements, an overall increase in the fall arrester surface can be achieved.

An important aspect of the invention relates to the design of a post stabilizer which is intended for use in combination with a conventional cable holding device. Known cable holding devices consist of at least one vertical post which is connected to a stand element lying in the plane. Accordingly, the post stabilizer according to the invention, which is placed on the cable holding device from above, has an opening at the top in the area of its upper side and an opening at the bottom in the area of its underside for receiving the post. The post stabilizer preferably at least partially surrounds the lateral surface of the post and extends in the vertical direction up to at least one third of the total height of the post.

The stabilizing effect emanating from the post stabilizer is preferably achieved in that the post stabilizer placed on the post from above at least partially surrounds the lateral surface of the post and surrounds the post at least up to a third, but preferably at least up to half, of its total height. The post stabilizer rests directly on the post, at least with its upper end section, and thereby stabilizes it.

In a preferred embodiment, the post stabilizer integrated in the fall arrester is designed as a post shell, with the post shell having the shape of a cone or a hemisphere.

The two preferred forms are characterized in that the opening on the bottom in the area of the underside has a larger diameter than the opening on the top in the area of the top. As a result, a plurality of post stabilizers can be stacked one on top of the other and thus stored and transported in a space-saving manner.

In a particularly preferred embodiment, the post cover integrated in the fall arrester has at least one layer made of a glass fiber reinforced composite material (GRP layer), the GRP layer forming a coherent layer with the GRP layer of the multi-layer fall arrester.

Particular stability is achieved when the post stabilizer designed as a post cover has at least one layer that consists of a GRP material and at the same time forms a layer of the multi-layer fall arrester. A large number of such connected layers causes a corresponding improvement in the stability of the connection between the post stabilizer and the fall arrester.

Most preferred is an embodiment in which the post cover integrated in the fall arrester has a base lying in the plane, the base connected to the fall arrester having at least a three-layer structure, and the top layer and bottom layer of the base made of a fiberglass-reinforced material composite material (GRP layer).

The at least three-layer structure is characterized in that a GRP layer is provided as the top and bottom layer. After the hardenable polymer that is applied to the glass fiber mat during the manufacture of the post cover has hardened, the two GRP layers mentioned bring about a sandwich-like bundling of the intermediate layers.

• einem gewebten oder einem nichtgewebten Stoff, und/oder
• einem biegbaren Metall, und/oder
• einem elastischen Polymer auf.

In a further preferred embodiment, the multi-layer base of the post stabilizer connected to the fall arrester has at least one layer in addition to at least one layer of a composite material reinforced with glass fibers (GRP material).

• a woven or a non-woven fabric, and/or
• a bendable metal, and/or
• an elastic polymer.

The sandwich-like structure is characterized by the fact that the flexible metal causes a certain rigidity in the base area, while the layer of elastic polymer gives the base area the elasticity and strength required in the event of a fall. Depending on the thickness of the intermediate layers, the thickness of the top and bottom GRP layers can vary.

In a further preferred embodiment, the post stabilizer integrated in the fall arrester, which is designed as a post shell, has a lower reinforcement in the area of the base and/or an upper reinforcement in the upper end section.

The lower reinforcement in the base area and the upper reinforcement in the upper end section are connected to one another by the lateral surface of the post shell. The lateral surface of the post shell can be made comparatively thin because in the event of a fall the post shell does not tear due to the upper reinforcement, but is pressed down by the bending post. The post shell, which is pushed together under this movement, is stabilized by the lower reinforcement in the area of the base. The damping effect of the post shell in this embodiment is therefore primarily due to the change in shape of the GRP material of the lateral surface.

• ein Metallblech mit mittiger Öffnung, wobei der Randbereich der mittigen Öffnung nach oben oder nach unten umgebogen ist, und/oder
• einen Ring, der aus einem Metallprofil mit kreisrundem Querschnitt geformt ist, und/oder
• einen mehrlagigen, zumindest teilweise aus einem mit Glasfasern verstärkten Composite-Material (GFK-Material) bestehenden Ring mit kreisrundem oder polygonalem Querschnitt.

A particularly preferred embodiment of the fall arrester relates to the design of the lower reinforcement in the base area of the post stabilizer designed as a post cover. This post cover has a lower reinforcement in the area of the base, the reinforcement being formed by

• a metal sheet with a central opening, the edge area of the central opening being bent upwards or downwards, and/or
• a ring formed from a metal profile with a circular cross-section, and/or
• a multi-layer ring with a circular or polygonal cross-section, at least partially made of a composite material reinforced with glass fibers (GRP material).

With the forces acting in the event of a fall, the deflecting post can easily have a cutting effect on its surroundings. The reinforcement lying in the base area through the previously mentioned alternative options ensures that the fall arrester is not destroyed in the base area by the bending post in the event of a fall.

A second essential aspect of the invention relates to an embodiment of the fall arrester with integrated post anchoring, the fall arrester comprising a central opening serving as post anchoring for receiving a post or a post adapter and the edge area of the central opening having a reinforcement.

• ein Metallblech mit mittiger Öffnung, wobei der Randbereich der mittigen Öffnung nach oben (aufgekantet) oder nach unten umgebogen ist, und/oder
• einen Ring, der aus einem Metallprofil mit kreisrundem Querschnitt geformt ist, und/oder
• einen mehrlagigen, zumindest teilweise aus einem mit Glasfasern verstärkten Composite-Material (GFK-Material) bestehenden Ring mit kreisrundem oder polygonalem Querschnitt, wobei das GFK-Material in den mehrschichtigen Aufbau des Fangschlittens integriert ist.

The reinforcement of the post anchoring in the edge area of the central opening of the fall arrester can be formed by

• a metal sheet with a central opening, the edge area of the central opening being bent upwards (upturned) or downwards, and/or
• a ring formed from a metal profile with a circular cross-section, and/or
• a multi-layer ring with a circular or polygonal cross-section, at least partially made of a composite material reinforced with glass fibers (GRP material), the GRP material being integrated into the multi-layer structure of the fall arrester.

The reinforcement of the post anchoring brings about the advantages already mentioned above in connection with the reinforcement of the fall arrester.

A further aspect of the invention relates to the intentional insertion of predetermined breaking points in the area of the post stabilizer and/or the post anchorage. It is provided that the post stabilizer has at least one predetermined breaking point and/or the post anchorage has at least one predetermined breaking point.

Selected areas of the post stabilizer and/or the post anchorage are deliberately weakened by predetermined breaking points, whereby the device nevertheless withstands the static horizontal force of 0.7 kN prescribed by the safety regulations. The weakening can only affect individual sections or several sections, or all components of the post stabilizer or the post anchorage. For example, it is conceivable that the post stabilizer designed as a post shell is reinforced in the base area, but has a number of predetermined breaking points in the area of the lateral surface and on the top of the post shell. The predetermined breaking points can either be formed by preformed openings or incisions or can be achieved by weakening the layer thickness. A combination of both measures is also conceivable.

Accordingly, in a particularly preferred embodiment, it is provided that the post stabilizer integrated in the fall arrester has at least one predetermined breaking point in the area of the opening at the top, and/or at least one predetermined breaking point in the area of the lateral surface of the post stabilizer, and/or at least in the area of the base connected to the fall arrester has a predetermined breaking point.

In a particularly preferred embodiment, it is provided that the post stabilizer has several predetermined breaking points arranged in a row one above the other in the area of its lateral surface.

The predetermined breaking points arranged in a row one above the other have the effect of a perforation line. The tearing of the post cover along the perforation line under the influence of the bending post can be made more difficult, e.g. because the layer thickness of the post cover increases in the direction of the base. The line of perforations causes a controlled course of cushioning with regard to the location of the cushioning and the extent of the cushioning.

In a very particularly preferred embodiment, the post stabilizer designed as a post cover has in the region of the upper side central opening as a predetermined breaking point at least one outgoing from the central opening longitudinal opening.

The longitudinal opening establishes the direction of controlled rupture of the post sleeve under the action of the deflecting post.

In the most preferred embodiment of the aforementioned type of fall arrester, the post cover has at least three predetermined breaking points in the area of the opening at the top, with the predetermined breaking points designed as incisions or longitudinal openings being arranged at the same distance from one another, starting from the central opening.

The three longitudinal openings define one of the possible directions of controlled rupturing of the post cover under the action of the deflecting post.

In a special embodiment, the post stabilizer integrated in the fall arrester, or the post anchorage integrated in the fall arrester, has a recess on the underside. The size of the recess corresponds in each case to the shape and height of the stand element belonging to the fall protection.

The recess provided for receiving the post anchorage or for receiving the stand element is dimensioned such that the underside of the recess has only a very small distance to the top side of the stand element. This causes contact between the stand element and the material on the underside of the recess under the roof ballast, which presses down on the base area of the post stabilizer or the post anchorage. This contact causes an additional stabilization of the respective cable holding device.

The above-described embodiments of the fall arrester can each preferably have two or more lobe-like ballast receiving elements arranged at the same distance from one another in order to increase the bearing surface, the ballast receiving elements being on the top side and/or are connected at least in sections on the underside to a glass fiber reinforced composite material (GRP material), which is also part of the post cover or the post anchorage.

Since the connection between the ballast receiving elements and the safety carriage is flexible in each case, the ballast receiving elements can be folded down or up to save space during transport of the stackable safety carriage with a semicircular or conical cross section.

An additional aspect of the invention relates to the post stabilizer as such, which was explained above in connection with the fall arrester, since this can also be used independently

The aspects and advantages mentioned above with regard to the post stabilizer or the post stabilizer designed as a post cover also apply to the post stabilizer according to the invention as such. This applies to the damping properties explained in connection with the multi-layer structure of the post stabilizer and to the predetermined breaking points explained in connection with the post stabilizer.

Due to these advantageous properties alone, the post stabilizer, which is also multi-layered at least in sections, does not necessarily have to be used in connection with a multi-layer fall arrester, but can be used independently.

With regard to the post stabilizer as such, the object of the invention is therefore to provide a damping element for a cable holding device which has at least one standing element (support surface) lying in the plane and a vertical and deformable post fastened on the top of the standing element.

  • at least partially surrounds the lateral surface of the post, and
  • extends in the vertical direction at least one third of the total height of the post, where
• at least one of the layers of the multi-layer post skin comprises a glass fiber reinforced composite material (GRP layer).

As explained above, the advantageous properties of the post stabilizer are also based on the multi-layer nature of the post stabilizer.

A post stabilizer designed as a post cover absorbs the required static horizontal force of 0.7 kN and can therefore be used with any type of fall arrester, i.e. the post cover according to the invention can be used as an independent damping element.

In addition to its function as a damping element, a post stabilizer designed as a post cover can also fulfill a signaling function by being painted with a fluorescent paint or by installing lamps (e.g. light-emitting diodes (LED)). A scale on the lateral surface can also mark the height up to which the respective individual layers belonging to a green roof structure should reach.

In a preferred embodiment, the post stabilizer is designed as a post cover and has at least one predetermined breaking point.

• the lateral surface of the post stabilizer at least one predetermined breaking point, and/or in the area
• of the base connected to the fall arrester

at least one predetermined breaking point is arranged in each case.

In addition to the damping function, the predetermined breaking points also have an indicator function, i.e. a tear at a predetermined breaking point indicates that a fall has occurred or at least a load similar to a fall has occurred.

In a preferred embodiment, in the case of the post stabilizer designed as a post cover, at least one of the layers of the multi-layer post cover is made of a composite material reinforced with glass fibers (GRP layer).

A three-layer structure in the area of the base is very particularly preferred, with the respective top layer and bottom layer of the base consisting of a composite material (GRP layer) reinforced with glass fibers.

An essential aspect of the post stabilizer relates to the enlargement of the contact surface through additional flat or lobe-like ballast absorption elements.

• einen mehrlagigen, zumindest teilweise aus einem mit Glasfasern verstärkten Composite-Material (GFK-Material) bestehenden Ring mit kreisrundem oder polygonalem Querschnitt.

The reinforcement in the area of the base is preferably formed by

• a metal sheet with a central opening, the edge area of the central opening being bent upwards or downwards, and/or
• a ring formed from a metal profile with a circular cross-section, and/or
• a multi-layer ring with a circular or polygonal cross-section, at least partially made of a composite material reinforced with glass fibers (GRP material).

In a further special embodiment, the post stabilizer designed as a post shell has in the area of its lateral surface several predetermined breaking points arranged in a row one above the other and/or in the area of the base at least one predetermined breaking point and/or in the area of the top central opening as a predetermined breaking point at least one starting from the opening longitudinal openings.

A very particularly preferred post stabilizer is a post cover that has at least three predetermined breaking points in the area of the opening at the top, with the predetermined breaking points designed as incisions or as longitudinal openings, starting from the central opening, being arranged at the same distance from each other, i.e. in a star shape.

The aspects and special features relating to the post stabilizer as such have the corresponding effects and advantages explained above for the same features (predetermined breaking points, reinforcements, enlargement of the contact surface) in connection with the fall arrester.

Cone-shaped post shell with predetermined breaking points in the base area and in the area of the lateral surface

1 shows a cross-section of a conical post stabilizer 4 with a multi-layer structure in the base area 4d. The base area 4d is first of all distinguished in its shape by the fact that it has a recess 4p in the lower area, the shape and size of which corresponds to the stand element (not shown) of one that can be inserted into the post stabilizer Cable holding device corresponds. This allows the fall arrester 1 with the integrated cone-shaped post stabilizer 4a to be placed on the rope holding device 2 from above (as in 7 shown) without the fall arrester 1 being deformed in the area above the standing element.

The multilayer structure in the base area 4d has two further layers 4n, 4m in addition to the upper GRP layer 4e and the lower GRP layer 4f. In the example shown, the layer 4n consists of a metal sheet and the second layer 4m consists of a woven or non-woven fabric (Vilestoff). To build up the multi-layer base 4d, after the lower GRP layer 4e has been applied, a disc-shaped disc made of sheet metal 4n is placed on top of the cone. The layers 4m and 4e are then applied. The multi-layer structure has special deformation properties simply because of the encasing by the outer GRP layers 4e and 4f, which frame the multi-layer structure.

2 shows the layer structure of a post stabilizer 4, which is designed as a cone-shaped post shell 4a, in detail. A metal 4n is arranged as an additional layer between the upper layer 4e and the lower layer 4f. The metal 4n is folded up in the base area of the post shell 4a and thereby causes a reinforcement 4g of the post stabilizer 4 in the lower area, ie in the area of the base 4d of the post shell 4a. Alternatively or additionally, the layer 4n can consist of a polymer 4o instead of metal. Besides the metal 4n, a woven or non-woven fabric 4m is integrated between the upper layer 4e and the lower layer 4f. The bottom picture of 2 show the

Post shell 4a in cross section with the top opening 4b and the bottom opening 4c and the bottom recess 4p.

The cone-shaped post stabilizer 4a integrated into the fall arrester 1 has a multi-layer structure. The outer layers, i.e. the upper layer 4e and lower layer 4f, each consist of a GRP material, which at the same time forms the outside and inside of the cone belonging to the post stabilizer 4. At the same time, the two outer layers 4e, 4f protrude in the radial direction beyond the base and form the surface of the fall arrester 1 adjoining the base area 4d. I.e. in this section of the fall arrester 1, the load-bearing layer 4m is made of a woven or non-woven material from the two outer layers 4e, 4f sandwiched.

3 Figure 12 shows a conical post stabilizer 4a with a top opening 4b and a bottom opening 4c. Through the top opening 4b of the post stabilizer 4 protrudes the upper end of the post with the cable attachment 2g. The base area of the post stabilizer 4 rests on the top of the standing element and weights the same.

Figure 4a shows a cable holding device 2 consisting of a post and a stand element, which has a cable attachment 2g at the upper end, in cross section. A flat material, which can consist of a woven or non-woven fabric 1c, lies on the standing element 2b to increase the surface area. Nonwovens are very particularly preferred as sheet material. The fall arrester has a central opening which is provided for receiving the post. The connection between the conical post stabilizer 4 and the ballast receiving element 4m/1c (catcher carpet) can also be made as a detachable connection using screws or rivets. The components mentioned together make up fall protection 6.

Figure 4b shows an alternative embodiment of FIG Figure 4a shown device. At the in Figure 4b shown embodiment, the fall arrester 1 is not made of a flat material, but of a grid-like material 1d. The one provided for the green roof structure Bulk material penetrates into the interstices of the mesh fall arrester 1d and thereby increases the frictional resistance of the fall arrester 1 in the event of a fall. The components mentioned together make up fall protection 6.

Figure 4c shows an alternative embodiment of FIG Figure 4b Fall Protection 6 shown. The Fall Protection 6 in Figure 4c is characterized in that a ballast receiving element 1c made of a woven or non-woven material is additionally connected to the base 4d of the post cover 4a in addition to the grid safety slide 1d.

figure 5 shows a cone-shaped post stabilizer 4a from the top. Its upper side has a total of 4 predetermined breaking points 4i, with the predetermined breaking points 4i in the form of longitudinal openings each starting from the central opening 4b. In the event of a load, the longitudinal openings 4i allow a post to be torn in a controlled manner into the top side and the subsequent lateral surface of the post cover 4a. The designed in the form of longitudinal openings predetermined breaking points 4i are arranged at the same distance from each other in a star shape. As a result, the post 2a, which bends over in the event of a load, is guided into the nearest longitudinal opening 4i in each case.

In the lower area, the conical post stabilizer 4a shown from the top view has four surface elements 4q made of GRP material and shaped like lobes. These surface elements 4q stabilize the base 4d and also increase the bearing surface, so that a post shell 4a equipped with the surface elements 4q is fixed even better by the load of the green roof. An additional enlargement of the contact surface is achieved by the ballast receiving element 4m.

The post shell 4a has the reinforcement 4g in the base area. In the upper end section, the post shell 4a has the upper reinforcement 4a.

6 shows the in figure 5 illustrated post stabilizer in an embodiment without the reinforcements 4g, 4h.

7 shows a cable holding device 2 with a post 2a and a stand element 2b, the post 2a having a spirally bent post section 2d in the middle section. The spiral winding in the post section 2d provides additional damping in the event of a fall. The post has a rope attachment 2g at the upper end section. In the example shown, the cable attachment 2g consists of an annular opening. Alternatively, the cable attachment can consist of a carabiner or a bayonet catch.

The post 2a of the cable holding device 2 can also be constructed in several parts and does not have to merge into the stand element 2b in one piece, but can, as in FIGS Figures 8 to 11 be connected to a post adapter.

8 shows the fall protection 6 with a multi-layer fall arrester section 3b and a post anchorage 5 under the load of the green roof 7.

The multi-layered fall arrester section 3b, the upper GRP layer 3a, the lower GRP layer 3e and the layer 3f made of a woven or non-woven fabric, which increases the fall arrester area as a ballast absorbing element.

The post anchor 5 serves as an anchor for the post adapter 2f. The post anchorage 5 has a recess 5f which corresponds in shape and size to the cross section of the upper section of the post adapter 2f. In the example shown, the post 2a is constructed in several parts, with the lower part protruding beyond the green roof 7 being formed by the adapter 2f bent in a U-shape. The post adapter 2f includes the lateral extensions lying in the plane, on the upper side of which the post anchorage 5 integrated into the fall arrester rests. The U-shaped section of the post adapter 2f protrudes through the central opening 5a of the post anchorage and is accessible from above for fastening the post 2a.

9 shows the post anchorage 5 together with the post 2a attached to the post adapter 2f. The post 2a is surrounded by a sheath. In the event of a fall, the post 2a is deflected and the shell detaches from its original position, so that the stress on the post is indicated. The post anchorage has the recess 5f on the underside. In the area of the opening 5a, the post anchorage 5 has a multilayer structure, with the upper layer 5b and the lower layer 5c being formed from a glass fiber reinforced material. The ballast receiving element 3f/1c is integrated between the layers 5b and 5c in order to increase the area of the fall arrester.

The multi-layered fall arrester section 3d is formed by reinforcement made of an elastic material 3d, the layer 3f made of a woven or non-woven fabric, and the metal reinforcement 3c, besides the outer GRP layers 3a, 3e.

10 shows the post adapter 2f, which is integrated into the opening 5a of the post anchorage, in that the lateral sections of the post adapter 2f protrude into the multi-layer fall arrester section 3 and are integrated therein. The connection between the lateral sections of the post adapter 2f and the layers of the multi-layer fall arrester 3 in the area of the opening 5a can be made either by fastening means, such as screws, or by an adhesive. Vertical, layer-penetrating openings are provided to allow the adhesive to penetrate the various layers. The post 2a is connected to the post adapter 2f by the lock nut 2e. Instead of the lock nut 2e, a thread can also be cut into the metal post adapter 2f so that the post 2a can be fastened thereto.

11 shows a multi-layer post adapter 2f whose lateral sections are integrated between the upper layer 5b and the lower layer 5c. The post adapter 2f has the reinforcement 5d in the area of the base. The reinforcement 5d provides additional stabilization of the post adapter 2f in the event of a fall and a Improvement in cushioning. The post 2a is connected to the post adapter 2f by the lock nut 2e. Instead of the lock nut 2e, a thread can also be cut into the post adapter 2f or a threaded nut can be integrated into the multi-layer post adapter 2f made of GRP material, so that the post 2a can be fastened to it without a lock nut.

12 shows a post stabilizer 4, which consists of two substantially U-shaped bent flat steel sheets, the two U-shaped bent sheets, which together form four cross braces 4l, are arranged perpendicular to one another, so that the post stabilizer 4 is opposite to a post inserted in the stabilizer , which is bent into the plane in the event of a fall, offers uniform stabilization. The top opening 4b of the stabilizer 4 is provided for the passage of the post.

13 shows a post stabilizer 4, which is designed as a post shell 4a in the shape of a cone. The special feature of the post cover 4a shown is that it has the lower reinforcement 4g in the base area 4d and the upper reinforcement 4g in the area of the upper end section of the post cover 4a. The two reinforcements 4g and 4h provide additional stabilization of the post cover in the event of a fall. In particular, the lower reinforcement 4g provides an improved connection between the post cover and the base area of the post stabilizer 4.
