Holder for a rope of a rope system for securing persons against falls, rope system for securing persons against falls, method for inserting a rope into such a holder, and safety device for such a holder

Description

[0001] The invention relates to a holder for a rope of a rope system for securing persons against falls, a rope system for securing persons against falls, a method for inserting a rope into such a holder and a securing element for such a holder.

[0002] Such a rope system comprises a rope, two rope end holders, and at least one rope holder. The end holders and the holder are attached to a substrate, such as a building component, particularly a roof, wall, or ceiling. The rope is clamped between the end holders at its ends. The holder is positioned between the end holders, holds the rope in a desired direction, and prevents excessive sagging. A carabiner or slider is typically guided along the rope, and a person requiring fall protection can connect their personal fall protection equipment to the carabiner or slider. In the event of a fall by the secured person, the resulting impact force is transferred to the substrate via the rope, the holders, and the end holders.

[0003] WO 2009 / 118407 A1 discloses an overhead cable system for a fall arrest system, comprising a safety cable, two end brackets for the safety cable, an intermediate bracket for the safety cable, and a runner. The intermediate bracket consists of a mounting base, a C-shaped bracket, and a guide tube. The mounting base is a U-shaped bracket with two aligned holes at the ends of the U-shaped legs. The mounting base has a hole in its center section, allowing it to be screwed to a lattice or masonry structure. The bracket has two opposing side faces or cheeks angled from a central section, with aligned holes at their upper ends. The bracket is hinged to the mounting base by means of a threaded bolt inserted through the aligned holes in the mounting base and the bracket. The cheeks of the bracket are recessed in the central section, giving them the shape of a C open to the left.The central section of the bracket is bent upwards at a 135° angle at its lower end, and the beginning of the upwardly sloping section is welded laterally to the lower ends of the cheeks, thus stiffening it. Further along, the upwardly sloping section is cantilevered, and the guide tube is welded to its end.

[0004] The guide tube is oriented parallel to the threaded bolt and has a long central section with a load-bearing cross-section and two shorter chamfers at the ends. The safety cable is free to move longitudinally within the guide tube. The inner diameter of the guide tube is larger than the diameter of the safety cable.

[0005] This well-known overhead rope system is installed by first attaching the end brackets and the intermediate bracket to the lattice or masonry structure, then threading the safety rope into the guide tube of the intermediate bracket, and finally attaching the ends of the safety rope to the end brackets. If the safety rope remains attached to the end brackets, the intermediate bracket cannot be detached from the rope without damage, nor can an additional intermediate bracket be installed.

[0006] DE 10 2012 110 659 A1 describes an intermediate support for a locking element which is rigidly attached to a locking point. The intermediate support has a holding section and a fastening section, wherein the holding section and the fastening section are connected to each other, wherein the fastening section is designed such that it can be permanently attached to the locking point, and wherein the holding section is designed such that it can subsequently be attached to the rigidly attached locking element and encloses the rigidly attached locking element.

[0007] EP 1 632 271 A1 describes an anchoring device for a safety line system, comprising a base for attachment to a supporting structure.

[0008] EP 1 122 381 A1 describes a device for fastening a rescue cable to a wall, wherein sleeves are provided.

[0009] The object of the present invention is to provide a holder for a rope of a rope system for securing persons against falls, into which the rope can be easily inserted.

[0010] Against this background, the invention proposes the subject matter of the independent claims. Advantageous embodiments of the invention are described in the dependent claims.

[0011] According to a first aspect, the invention proposes a holder for a rope of a rope system for securing persons against falls, comprising the combination of features of claim 1.

[0012] According to a second aspect, the invention proposes a rope system for securing persons against falls, comprising the combination of features of claim 5.

[0013] According to a third aspect, the invention proposes a method for inserting a rope into a holder designed according to the first aspect, with the combination of features of claim 7.

[0014] The invention proposes a locking element for or in a holder, which is designed according to the first aspect, comprising a first and a second half-tube and having a first area with an outer diameter.

[0015] The invention enables the rope to be easily inserted into the holder, and in particular, the holder to be easily attached to the rope, even after installation. This is because, unlike the overhead rope system known from WO 2009 / 118407 A1, the rope does not need to be threaded through a tubular component of the holder. Thus, with the rope system according to the invention, for example, a rope already clamped between two end holders does not need to be detached from the end holders. The invention makes it possible, in particular, to detach an already installed holder from the tensioned rope without causing damage, and to easily install a new and / or additional holder. Therefore, for example, an already installed holder can be safely replaced with another holder, since the person secured to the rope system does not need to detach the rope.

[0016] The installation of a new and / or additional holder can be carried out, for example, by first attaching the holder to the substrate and then inserting the rope into the holder according to the inventive method. Alternatively, the installation of a new and / or additional holder can also be carried out, for example, by first inserting the rope into the holder according to the inventive method and then attaching the holder with the inserted rope to the substrate. The invention also enables the installation of a rope system for securing persons against falls by, for example, first attaching end holders to the substrate, then attaching the ends of the rope to the end holders, then inserting the rope, particularly according to the inventive method, into a holder according to the inventive method, and finally attaching the holder with the inserted rope to the substrate.

[0017] The invention also enables the installation of a rope system to secure persons against falls, for example by first attaching end holders to the substrate, then attaching the ends of the rope to the end holders, then attaching a holder according to the invention to the substrate, and finally inserting the rope, in particular according to the method according to the invention, into the holder attached to the substrate.

[0018] The base and / or the first guide channel and / or the second guide channel can be designed in any way as required and can be made of or consist of, for example, metal, in particular steel or galvanized steel or stainless steel or non-corrosive steel.

[0034] In the following, embodiments of the invention are explained in more detail by way of example with reference to the accompanying drawings. The individual features resulting therefrom are not limited to the individual embodiments, but can be combined with individual features described above and / or with individual features of other embodiments. The details in the drawings are to be interpreted as explanatory only, not as limiting. The reference numerals contained in the claims are not intended to limit the scope of protection of the invention in any way, but merely refer to the embodiments shown in the drawings.

[0035] The drawings show in FIG. 1 a perspective view of a first embodiment of a holder for a rope of a rope system for securing persons against falls; FIG. 2 A top view of a first embodiment of a rope system for securing persons against falls, wherein the rope system includes the holder made of FIG. 1 and includes a rope which is arranged diagonally in a gap of the holder with a rope section; FIG. 3 a perspective view of a second embodiment of the rope system, wherein the rope system comprises a second embodiment of the holder and the holder comprises two securing parts that are placed on opposite rope sections of the rope that lie outside the holder; FIG. 4 the rope system made of FIG. 3 , wherein the securing elements are inserted with a first area in guide grooves of the holder.

[0036] In FIG. 1 and FIG. 2 A first embodiment of a holder 10 according to the invention for a rope 12 of a rope system 14 for securing persons against falls is shown schematically. FIG. 2 A first embodiment of a rope system 14 according to the invention for securing persons against falls is also shown schematically. In this embodiment, the rope system 14 comprises the holder 10 and a rope 12 with an outer diameter. The holder 10 comprises a substantially L-shaped base 16, a first guide channel 18 for the rope 12, which has a first longitudinal slot 20, and a second guide channel 22 for the rope 12, which has a second longitudinal slot 24. The rope 12 is guided in the guide channels 18, 22. Each longitudinal slot 20, 24 has a width that is greater than the outer diameter of the rope 12.

[0037] The base 16 includes, for example, a mounting plate 26 with a through-hole (not shown) and a first and a second retaining leg 28', 28", which are attached to the mounting plate 26. A screw 30 is guided through the through-hole and can be anchored in a substrate, such as a building component, so that the holder 10 is attached to the substrate. In this embodiment, the base 16 and the guide grooves 18, 22 are, for example, made of stainless steel. The retaining legs 28', 28" are, for example, formed in one piece or monolithically with the mounting plate 26, but can also be attached to the mounting plate 26 in other ways, for example by gluing and / or riveting and / or screwing and / or welding. FIG. 1 The base 16 is aligned such that the mounting plate 26 is arranged horizontally and the retaining legs 28', 28" are arranged parallel to each other at a distance and project upwards at right angles from the mounting plate 26.

[0038] The guide channels 18, 22 are attached to the free, upper ends of the retaining legs 28', 28" at a distance from each other, for example by welding, such that they are aligned with each other and coaxially aligned with respect to a longitudinal axis A. Thus, the guide channels 18, 22 are attached to the base 16 in alignment with respect to the longitudinal axis A such that a gap 32 is formed between the guide channels 18, 22. The gap 32 has a width that is greater than the outer diameter of the cable 12, as shown in FIG. 2 This can be seen. The first longitudinal slot 20 is rotated relative to the second longitudinal slot 24 with respect to the longitudinal axis A by an angle of approximately 90°, such that in FIG. 1 the first longitudinal slot 20 points downwards to the left and away from the base 16 and the second longitudinal slot 24 points downwards to the right and towards the base 16.

[0039] With reference to FIG. 2 und FIG. 3 A first embodiment of a method according to the invention for inserting a rope 12 into a holder 10 is described below, wherein the holder 10 is designed by way of example according to the first embodiment.

[0040] Initially, the holder 10 is attached to a substrate not shown by passing the screw 30 through the through hole of the base 16 and anchoring it in the substrate.

[0041] Subsequently, the holder 10 and the rope 12 are aligned relative to each other such that the longitudinal axis A runs obliquely to a first rope section 12' of the rope 12.

[0042] The rope section 12' is then inserted into the gap 32 between the guide channels 18, 22, as shown in FIG. 2 is shown.

[0043] Finally, the holder 12 is rotated relative to the rope section 12' towards the longitudinal axis A such that the rope section 12' with its in FIG. 2 right, lower end from below through the first longitudinal slot 20 into the first guide groove 18 and with its in FIG. 2 The left upper end is moved from above through the second longitudinal slot 24 into the second guide channel 22 and runs essentially coaxially to the longitudinal axis A. Consequently, the rope section 12' runs essentially coaxially in the guide channels 18, 22, as shown in FIG. 3 is shown.

[0044] In this embodiment, the rope 12 is also attached to the substrate. This is done, for example, by attaching two end brackets (not shown) to the substrate and clamping the rope 12 between the end brackets. The rope 12 can be attached, for example, before or after the bracket 10 is attached.

[0045] In FIG. 4 A second embodiment of the cable system 14 is shown schematically; this embodiment is similar to the first embodiment, so the differences will be explained in more detail below. In this embodiment, the holder 10 is designed according to a second embodiment; this embodiment is similar to the first embodiment, so the differences will be explained in more detail below.

[0046] In this embodiment, the holder 10 additionally comprises, by way of example, a first locking element 34, which includes a first and a second half-tube 36', 36". The locking element 34 has an inner diameter that corresponds to the outer diameter of the cable 12. The half-tubes 36" and 36" surround the cable 12. The locking element 34 has, by way of example, a first section 38' with an outer diameter that corresponds to an inner diameter of the first guide groove 18 and that is larger than the width of the first longitudinal slot 20. The locking element 34 is arranged with the first section 38' in the first guide groove 18. The locking element 34 also has, by way of example, a second section 38" that tapers conically away from the first section 38'.The second area 38" has an outer diameter adjacent to the first area 38' which is larger than the outer diameter of the first area 38' and corresponds to an outer diameter of the first guide groove 18.

[0047] The holder 10 additionally comprises, by way of example, a second securing element 40, which includes a first and a second half-tube 42', 42" and is designed analogously to the first securing element 34. The securing element 40 has an inner diameter that corresponds to the outer diameter of the cable 12. The half-tubes 42", 42" surround the cable 12. The securing element 40 has, by way of example, a first section 44' with an outer diameter that corresponds to an inner diameter of the second guide groove 22 and that is larger than the width of the second longitudinal slot 24. The securing element 40 is arranged with the first section 44' in the second guide groove 22. The securing element 40 also has, by way of example, a second section 44" that tapers conically away from the first section 44'.The second area 44" has an outer diameter adjacent to the first area 44' which is larger than the outer diameter of the first area 44' and corresponds to an outer diameter of the second guide groove 22.

[0048] Each half-tube 36', 36", 42', 42" is, by way of example, manufactured from stainless steel overmolded with a thermoplastic. A longitudinal edge of the 36' half-tube is pivotally connected to a longitudinal edge of the 36" half-tube by means of a film hinge (not shown). A longitudinal edge of the 42' half-tube is pivotally connected to a longitudinal edge of the 42" half-tube by means of a film hinge (not shown).

[0049] With reference to FIG. 3 and FIG. 4 A second embodiment of the method is described below, wherein the holder 10 is designed by way of example according to the second embodiment; this embodiment of the method is similar to the first embodiment, so that the differences are mainly explained in more detail below.

[0050] In this embodiment, the first securing element 34 is attached to a second rope section 12" of the rope 12, which is located outside the holder 10, namely in FIG. 3 to the left of the holder 10, placed by placing the half-tubes 36', 36" around the rope section 12" from opposite sides so that they enclose the rope 12, as shown in FIG. 3 is shown.

[0051] The safety element 34 with the first section 38' is then inserted into the first guide groove 18 by pushing the safety element 34 along the rope section 12" into the guide groove 18 until the second section 38" rests against the guide groove 18, as shown in FIG. 4 as shown. Since the outer diameter of the first area 38' is larger than the width of the first longitudinal slot 20, the rope 12 cannot slip through the longitudinal slot out of the guide channel 18 and thus detach itself from the holder 10.

[0052] The securing element 34 can be attached at a suitable time as required, for example before or after attaching the holder 10 and / or before or after aligning the holder 10 and the rope 12 and / or before or after inserting the first rope section 12' and / or before or after rotating the holder 10 relative to the first rope section 12' and / or before or after attaching the rope 12.

[0053] Furthermore, the second securing element 40 is attached analogously to the first securing element 34 to a third rope section 12* of the rope 12, which is outside the holder 10, namely in FIG. 3 to the right of the holder 10, placed by placing the half-tubes 42', 42" around the rope section 12* from opposite sides so that they enclose the rope 12, as shown in FIG. 3 is shown.

[0054] Subsequently, the safety element 40 is inserted into the second guide groove 22 analogously to the safety element 34 with the first section 44', by pushing the safety element 40 along the rope section 12* into the guide groove 22 until the second section 44" rests against the guide groove 22, as shown in FIG. 4as shown. Since the outer diameter of the first area 44' is larger than the width of the second longitudinal slot 24, the rope 12 cannot slip through the longitudinal slot 24 out of the guide channel 22 and thus detach itself from the holder 10.

[0055] The securing element 40 can be attached at a suitable time as required, for example before or after attaching the holder 10 and / or before or after aligning the holder 10 and the rope 12 and / or before or after inserting the first rope section 12' and / or before or after rotating the holder 10 relative to the first rope section 12' and / or before or after attaching the rope 12 and / or before or after or simultaneously with attaching the securing element 34 and / or before or after or simultaneously with inserting the securing element 34.
