Description

The invention relates to a stop arrangement, which does not penetrate the roof skin, for anchoring a safety harness for a person to be secured against falling from the roof of a building. Furthermore, the invention also relates to at least one stop unit each consisting of two stop arrangements designed and interacting in this way.

Stop units for installation on an almost flat surface, which surface is arranged at a distance from the ground or ground surrounding the surface in the vertical direction, are already available on the market in many different designs. Such a stop unit describe, among other things, for example AT519981 B1 , GB2353818A , AT519224A4 or the DE10333113 B3 . These anchor units are positioned at the designated location on the roof and held based on weight.

Another anchorage point based on a clamping effect for securing people is from the utility model DE202008016445U1 known. This attachment point is clamped directly to the flanged profile in the area of the flanged profile without damaging the roof skin of a flanged seam roof. For this purpose, each of the attachment points is equipped with a clamp that can be placed on the flanged profiles and clamped to them using suitable clamping devices. Clamping screws are provided as clamping elements, by means of which the clamp can be fastened to the flanged profile accommodated therein. A securing element for releasably receiving an end of a cable is also attached to the clamp, the securing element being designed as a deformable sheet-metal strap. One end of the sheet metal tab rests freely rotatably on a surface of the clamp and is screwed to it. The free end of the securing element is in the form of an eyelet and is angled upwards relative to the end resting on the clamp. This design has proven itself in principle, but had the disadvantage that damage to the flanged profile could not be ruled out in the event of a fall. In particular, this is also due to the fact that the clamping force is concentrated over a large area by means of the clamping screws.

The object of the present invention was to overcome the disadvantages of the prior art and to provide a stop assembly and a stop unit comprising two of these components, by means of which a user is able to carry out simple and secure assembly and in which a Fall load damage in the seam area of the roofing can be prevented.

This object is achieved by a stop arrangement and a stop unit formed from this according to the claims.

The stop arrangement according to the invention serves to anchor a safety harness for a person to be secured against falling from a building roof. This stop arrangement is designed to be attached to a seam of a seamed roof and to be mounted for its fuse on the seam web projecting directly from the roof. For its part, the attachment arrangement can be used directly for hanging in one end of a safety cable that can be latched in on the person. Furthermore, it would also be possible to provide several stop arrangements and use them to form a type of cable railing on the roof of the building for security purposes.

The stop assembly includes in turn

• - a clamping module with a clamping body and a clamping device, wherein the clamping body defines a receiving space at least for a flanging of the fold, and
• - At least one stop element, which is also provided
• - that the clamping body has its own left clamping body part and its own right clamping body part, which clamping body parts face each other in their initial position and also in their clamping position,
• - that each of the clamp body parts has a clamp body head part and a clamp body foot part,
• - that each clamping body head part, viewed in cross section, comprises a base web and an upper first leg and a lower second leg projecting from this in the direction of the respective other of the clamping body parts,
• - that the receiving space is defined at least for the flanging of the fold of the two clamping body head parts,
• - that when the clamping body parts are in the initial position and/or in the clamping position, the two upper first legs of each of the clamping body head parts rest against one another,
• - that the clamping device comprises at least one connecting element, but preferably comprises a plurality of connecting elements arranged one behind the other in the direction of the longitudinal extension of the clamping body parts, and the at least one connecting element passes through each of the two base webs and is separated from the connecting element gan the two clamping body head parts can be pressed against each other in the clamping position with a preload force,
• - that subsequent to each lower second leg of the clamping body head parts, a transition section is arranged in each case towards the respective clamping body foot part and each of the transition sections facing one another defines a clamping section for a fold web of the fold,
• - that the clamping body foot parts are each arranged to run in opposite directions with respect to the upper first leg of the clamping body head parts, and
• - That can be kept clamped between the clamping sections with the prestressing force built up by at least one connecting element of the fold bar of the fold outside of the fold flange.

The advantage achieved in this way is that such a defined clamping force is applied to the fold web of the fold located between the two clamping sections by means of the at least one connecting element of the clamping device. The two first legs rest against one another with their leg ends facing one another, with a type of pliers clamping being exerted or applied by means of the connecting element or elements on the clamping body sections forming the respective transition section towards the clamping body foot part.

One of the clamping sections is formed in each case by the alignment of the lower second legs running towards one another and the respectively adjoining transition section. The clamping force is not applied directly to the fold by the connecting element or elements, but rather indirectly by the clamping sections formed on the two clamping body parts onto the fold web. This achieves a more extensive distribution.

The receiving space serves to receive the flanging of the fold in order to avoid damage to the same. The clamping sections are selected or arranged in such a way that the clamping on the fold outside of the flange in the sheet metal section projecting from the roof surface—namely the fold web of the fold—is effected. Furthermore, this also facilitates assembly, since the fold beading is arranged in the receiving space during attachment and the clamping takes place only or exclusively on the projecting fold web. Since the two clamping body parts forming the clamping body also have a sufficiently long longitudinal extent in the direction of the fold, canting or tilting of the clamping body in the event of a fall load is avoided. The two clamping body foot parts form an additional support or support surface on their side facing the roof, which mostly or predominantly rests on the roof surface in the clamped assembly state.

Furthermore, it can be particularly advantageous if the two clamping body parts are each formed from a shaped sheet metal part. This means that the clamping body parts can be easily adapted to a wide variety of applications. A ferrous material, in particular a high-grade steel, can be used as the material in a wide variety of material classes.

Another embodiment is characterized in that the two upper first legs are arranged to run parallel to one another and each protrude in a normal direction from the respective base web. In this way, mutual stable support of the two clamp body parts on one another can be made possible.

A further possible embodiment has the features that the two lower second legs each protrude at an obtuse angle from the respective base web on the side facing away from the respective upper first leg. In this way, better tolerance compensation for the fold web of the fold to be accommodated and a better clamping effect can be achieved.

A further embodiment provides that, viewed in cross section, the transition section located between the lower second leg and the respective clamping body foot part is rounded. In this way, sharp-edged clamping areas can be avoided and associated damage to the metal sheet in the clamping areas can be avoided.

Another embodiment is characterized in that an additional intermediate section is provided adjoining the respective transition section towards the clamping body foot part, which intermediate section, viewed in cross section, protrudes at an obtuse angle from the respective clamping body foot part in the direction of the respective other of the clamping body parts is trained. In this way, a sharp-edged transition between the clamping body foot part and the transition section can be prevented.

A further preferred embodiment is characterized in that of each of the clamping body foot parts a predominantly planar base surface is defined on the side facing away from the respective clamping body head part and that the two form the clamping sections the transition sections, are arranged at a distance from the respective base surface. In this way, when the stop arrangement is supported and placed on the roof surface, the clamping areas can be spaced apart from the angled area of the metal sheet towards the flanging of the fold.

Furthermore, it can be advantageous if, viewed in cross section and in the starting position, the two clamping sections of the transition sections facing one another are arranged at a distance from one another in the transverse direction with the upper first legs lying against one another.

In this way, a type of clamping pincer movement of the two clamping sections can be achieved when the prestressing force is applied by the clamping device.

A preferred embodiment is characterized in that the left-hand clamping body part and the right-hand clamping body part of the clamping body are essentially identical to one another when viewed in cross section and are arranged as mirror images of one another in their initial position and/or in their clamping position. Because the cross-sectional shape is essentially the same as one another, there is no longer any need to take account of an oriented alignment when mounting the stop arrangement on the fold. This creates the possibility of being able to attach and assemble the stop arrangement in any longitudinal orientation on the fold. This is independent of the position of the beading of the fold.

Another alternative embodiment is characterized in that in the direction of the longitudinal extension of the clamping body parts and preferably in a middle section thereof, the upper first leg is designed to be interrupted in a partial section in the right clamping body part and the left clamping body part adjoining its upper first leg in its longitudinal extension has a retaining tab that is adapted to the subsection that is designed to be interrupted, which retaining tab protrudes beyond the clamping body head part of the right clamping body part in the transverse direction to its longitudinal extension. An integral connection point for the stop element on the stop arrangement can thus be created. By engaging the holding tab in the recessed section of the first upper leg, better mutual stabilization and directed application of force into the fold, in particular its fold web, can be achieved.

Furthermore, it can be advantageous if at least one material severing through the wall thickness is arranged at least in the region of the clamping sections in each of the clamping body parts. A deliberately defined weakening can thus be provided in order to be able to form a target deformation area when a fall load is introduced.

A further embodiment provides that several material cuts are provided in each of the clamping body parts and each of the material cuts forms a slot. The slits create multiple material breaks throughout the material thickness. This is particularly the case in those partial sections of the clamping body parts which have been stiffened by edging or folding.

A further possible and optionally alternative embodiment has the characteristics that the at least one connecting element is formed by a screw and nut arrangement. This means that proven standard parts can be used to enable stable clamping, which can be adjusted with the tightening torque.

However, the object of the invention is also independently achieved by an attachment unit for anchoring a safety harness for a person to be secured against falling from a building roof.

• - zwei zusammenwirkende und erfindungsgemäß ausgebildete Anschlaganordnungen, wobei weiters
• - ein Verbindungselement vorgesehen ist, welches Verbindungselement in Querrichtung bezüglich der Längserstreckung der beiden Anschlaganordnungen angeordnet ist, und
• - das Verbindungselement an jeder der beiden Anschlaganordnungen gehalten und mit diesen verbunden ist.

Such a stop unit comprises

• - Two interacting stop assemblies designed according to the invention, with further
• - a connecting element is provided, which connecting element is arranged in the transverse direction with respect to the longitudinal extension of the two stop assemblies, and
• - The connecting element is held and connected to each of the two stop assemblies.

The advantage achieved in this way is that an even more stable and secure clamping and holding device can be created. This can also reduce the introduction of the impact force in the form of a torsional moment in the fold.

Furthermore, it can be advantageous if the connecting element is connected to the respective stop arrangement by means of at least one screw connection, preferably by means of several screw connections. In this way, an easily adaptable connection option can be created.

Another embodiment is characterized in that at least one stop element is provided and the at least one stop element is arranged on the connecting element. In this way, a type of kit can be created, since existing individual components can be used in order to create an even more stable fastening option.

For a better understanding of the invention, it is explained in more detail with reference to the following figures.

The term “in particular” is understood below to mean that it can be a possible more specific design or more detailed specification of an object or a method step, but does not necessarily have to represent a mandatory, preferred embodiment of the same or a mandatory procedure.

As used herein, the terms "comprising," "comprising," "having," "includes," "including," "includes," "containing," and any variations thereof are intended to cover non-exclusive inclusion.

In the 1 until 4 an exemplary embodiment of a stop arrangement 1 is shown, which is used to anchor a safety harness for a person to be secured against falling from a building roof 2 . The building roof 2 can form a bearing surface 3 for the stop arrangement 1 .

In the present embodiment, the stop arrangement 1 is fastened to a sheet metal roof mostly formed from sheet metal at the fold 4 connecting the sheet metal webs to one another and is thus positioned in a clamping effect. Such roof coverings are referred to as so-called seamed roofs, and the seam design can be designed differently according to the known prior art. A standing seam, a double standing seam, a round seam or the like is usually used. The entire fold 4 includes the area or section of the fold flange and that fold web that rises up from the mostly flat roof surface. The fold web usually has a folded longitudinal web from each of the sheet metal webs that are located next to one another and are to be connected to one another. The folding web is predominantly formed from or includes two such longitudinal webs.

The stop arrangement 1 in turn comprises a clamping module 5 with a clamping body 6 and a clamping device 7. The clamping body 6 defines or forms a receiving space 8 at least for the flanging of the seam 4 of the seamed roof, in order to attach it to its sheet metal sections protruding from the roof surface - To be held clamped or attached - namely the Falzstegen.

In order to create a simple fastening option for the person to be secured, at least one component, generally referred to as a stop element 9, is provided. This can be an eyelet, a shackle with a suspension eyelet or a post with an eyelet to form a railing and/or rope railing or the like.

The clamping body 6 comprises its own left-hand clamping body part 10 and its own right-hand clamping body part 11. The two clamping body parts 10, 11, viewed in their cross section, are basically identical to one another and are arranged in a fold plane extending in the longitudinal direction of the fold as mirror images of one another and thus opposite one another. So that the two clamping body parts 10, 11 are in their starting point ment and facing each other in their clamping position. The two clamping body parts 10 and 11 are preferably each formed from a shaped sheet metal part. This can be done by means of folding, bending or longitudinal profile forming. The starting material is usually sheet metal made from an iron material. The material is preferably made of stainless steel, with the most varied grades of stainless steel being able to be used depending on the place of use. In order to enable the components to be better differentiated from one another, separate reference numbers have been assigned for the left and right component components.

Each of the clamping body parts 10, 11 in turn has a clamping body head part 12, 13 and a clamping body foot part 14, 15. It should be mentioned that the individual components of the left and right clamping body parts 10, 11 that are listed in each case can also be referred to as left or right. Each of the clamping body head parts 12, 13 comprises, in cross section, i.e. in a normal plane with respect to the longitudinal extent of the fold, a base web 16, 17 and, starting from this, projecting in the direction of the respective other of the clamping body parts 11, 10, an upper first leg 18, 19 and a lower second leg 20, 21. The previously described receiving space 8 for flanging the fold 4 is defined by the two clamping body head parts 12 and 13 together.

In the present exemplary embodiment, the two upper first legs 18 and 19 are arranged to run parallel to one another and each protrude in a normal direction from the respective base web 16 or 17 . The two lower second legs 20 and 21 each project at an obtuse angle onto the side of the respective base web 16 or 17 facing away from the respective upper first leg 18 or 19 . A certain resilience and resilience of this section can be achieved by this obtuse angle.

If the two clamping body parts 10, 11 are in the starting position facing one another and/or also in their clamping position, the two upper first legs 18 and 19 of each of the clamping body head parts 12, 13 are in contact with one another. This on the respective longitudinal end faces.

The clamping device 7 comprises at least one connecting element 22 which is designed to press the two clamping body parts 10, 11 against one another and thus to build up the clamping force on the fold web of the fold 4. The at least one connecting element 22 can be formed by a screw and nut arrangement, for example.

Depending on the selected longitudinal extent of the clamping body parts 10, 11 and in order to apply a more uniform clamping force, several connecting elements 22 arranged one behind the other in the direction of the longitudinal extent of the clamping body parts 10, 11 can also be provided. The connecting element 22 passes through or the connecting elements 22 pass through each of the two base webs 16 and 17 and also penetrate the receiving space 8 for the flanging of the fold 4. The arrangement of the connecting element or elements 22 is selected so that physical contact with the one in the receiving space 8 Flanging of the fold 4 is prevented. In their clamping position, the two clamping body head parts 12 and 13 are pressed against one another with a prestressing force by the connecting element 22 or by the connecting elements 22, and the clamping force is thus built up.

It is also provided that a transition section 23 , 24 towards the respective clamping body foot part 14 , 15 is arranged or formed on each lower second leg 20 , 21 of the two clamping body head parts 12 and 13 . Each of the two transition sections 23, 24 has its own clamping section 25, 26 defined. Preferably, each of the two transition sections 23, 24, viewed in cross section, is formed with a rounded longitudinal course.

In addition, it would also be possible for an additional intermediate section 27, 28 to be provided adjoining the respective transition section 23 or 24 towards the clamping body foot part 14 or 15. Each of the two intermediate sections 27 or 28 is in turn designed to rise at an obtuse angle from the respective clamping body foot part 14 or 15 in the direction of the respective other of the clamping body parts 11 or 10, viewed in cross section. Furthermore, each of the two clamping body foot parts 14 and 15 forms or defines a predominantly planar base surface on the side facing away from the respective clamping body head part 12, 13. Through each of the two intermediate sections 27, 28 projecting in the direction of the clamping body head part 12, 13, the two transition sections 23, 24 forming the clamping sections 25, 26 are also arranged at a distance from the respective base surface of each of the clamping body foot parts 14 and 15 .

The subsequent to the respective transition section 23, 24 located clamping body foot parts 14, 15 are in turn arranged to run in opposite directions with respect to the upper first leg 18, 19 of the clamping body head parts 12, 13. This means that they each extend in the opposite direction, starting from the fold area.

If the two clamping body parts 10, 11 are slipped over the fold 4 in their initial position and the pretensioning force is applied to the two clamping body parts 10, 11 by at least one connecting element 22, the stop arrangement 1 is held against the fold web of the fold 4 in the region of its interacting clamping sections 25, 26 kept clamped.

the 3 shows the pre-positioned initial position of the stop arrangement 1. If the connecting element(s) 22 is/are pretensioned and the two clamping sections 25, 26 are moved towards one another, the clamping mounting takes place on the protruding fold web of the fold 4.

Furthermore, it can be advantageous if, viewed in cross section and in the initial position, the two clamping sections 25 and 26 facing one another of the respective transition sections 23, 24 are spaced apart from one another in the transverse direction with respect to the longitudinal extent of the clamping body parts 10, 11 in the case of the upper first legs 18, 19 which are arranged adjacent to one another are spaced apart at a distance. The distance should roughly correspond to the sum of the metal thicknesses in the bottom fold area - namely the fold web.

In order to create a simple fastening option for the at least one stop element 9 described above on the stop arrangement 1, in the direction of the longitudinal extent of the clamping body parts 10, 11 and preferably in a central section thereof in the right clamping body part 11, the upper first leg 19 can be designed to be interrupted in a partial section . This means that the partial section of the upper first leg 19 has been removed or not formed and there is thus a so-called clearance or receiving slot. The left-hand clamping body part 10 has, adjoining its upper first leg 18 , a retaining tab 29 whose longitudinal extension is adapted to the part section of the upper first leg 19 which is designed to be interrupted. The retaining tab 29 protrudes beyond the right clamping body head part 13 of the right clamping body part 11 in the transverse direction to its longitudinal extension. A receiving opening for a screw connection with a ring nut or the like, which can form the stop element 9, can be formed in that protruding section of the retaining tab 29, for example.

Furthermore, in an enlarged detail 1 as well as in the 3 It is also shown that, at least in the region of the clamping sections 25 and 26 in each of the clamping body parts 10, 11, at least one material severing 32 that penetrates the wall thickness is arranged or formed. A plurality of material cuts 32 are preferably provided in each of the clamping body parts 10, 11. A material severing 32 is understood to mean a complete interruption in the material, namely the clamp body parts 10, 11, extending to a certain length. In the present exemplary embodiment, the material cuts 32 are each formed or arranged in a section of the second legs 20, 21, the transition sections 23, 24, if provided the intermediate sections 27, 28, and an immediately adjacent section of the clamping body foot parts 14, 15.

If the holding tab 29 is also provided or formed, one of the material cuts 32 can be arranged at one end of the same in an aligned normal plane with respect to the longitudinal extension of the holding tab 29 . The material cuts 32 form a target deformation area in each of the clamping body parts 10, 11 in order to achieve a certain damping effect when a fall load is introduced.

In the 5 a possible exemplary embodiment of a stop unit 30 is shown, which is also used to anchor a safety harness for a person to be secured against falling from a building roof 2 .

The stop unit 30 comprises two of the stop assemblies 1 already described in detail above, each of which is arranged on its own fold 4 and is held clamped to each of the fold webs of the folds 4 .

For mutual connection, a separate connecting element 31 is provided between the two interacting stop arrangements 1, which can also be referred to as a coupling element. The connecting element 31 is in turn arranged between the two stop arrangements 1 in the transverse direction with respect to the longitudinal extension of the latter and is also held on each of the two stop arrangements 1 and is also connected to them. The connection between one of the end regions of the connecting element 31 and one of the stop assemblies 1 can be made, for example, by means of one or more screw connections. To adjust the length to different transverse distances between two folds 4, to which one of the stop assemblies 1 is clamped, several longitudinal slots can be provided or formed in the connecting element 31 for mutual connection and adjustment of the connection length.

In order to achieve a certain inherent rigidity of the connecting element 31, the two longitudinal edge sections can each be folded up have formed reinforcement bar. A type of U-profile or C-profile is thus formed.

The connecting element 31 is preferably attached to the retaining tabs 29 described above on each of the stop assemblies 1 . For this purpose, the two retaining tabs 29 can have an arrangement directed towards one another in the assembled state. Furthermore, the two retaining tabs 29 could each be arranged so as to project in the same transverse direction. However, the two retaining tabs 29 could also each be arranged so as to protrude in a direction or side facing away from one another.

An extent from a value range with a lower limit of 250 mm, in particular 350 mm, and an upper limit of 600 mm, in particular 450 mm, can be selected as the longitudinal extension of the stop arrangement 1 .

The exemplary embodiments show possible variants, whereby it should be noted at this point that the invention is not limited to the specifically illustrated variants of the same, but rather that various combinations of the individual variants with one another are also possible and this possibility of variation is based on the teaching on technical action through the present invention in skills of the specialist working in this technical field.

The scope of protection is determined by the claims. However, the description and drawings should be used to interpret the claims. Individual features or combinations of features from the different exemplary embodiments shown and described can represent independent inventive solutions. The task on which the independent inventive solutions are based can be found in the description.

All information on value ranges in the present description is to be understood in such a way that it also includes any and all sub-ranges, e.g. the information 1 to 10 is to be understood in such a way that all sub-ranges, starting from the lower limit 1 and the upper limit 10, are also included , i.e. all subranges start with a lower limit of 1 or greater and end with an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1, or 5.5 to 10.

Finally, for the sake of clarity, it should be pointed out that some elements are shown not to scale and/or enlarged and/or reduced in size for a better understanding of the structure.
