DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0078] Same or similar components in different figures are provided with same reference numerals. The representations in the figures are schematically.

[0079] FIG. 1 shows a system 100 for controlled roping down of a person 101 in an emergency situation out of a working area 102 that may be located at a distance to a ground. A first roping down system (or lowering system, or roping system) is provided, which may be for roping down the person 101 and which may be attachable to an attachment area in the working area 102, wherein the first roping down system may have a first rope 112 for roping down the person 101. A second roping down system for roping down the person 101 may be provided, wherein the second roping down system may have a second rope 122, to which the person 101 may be coupleable directly or indirectly. A suspension element 124 may be attachable to the attachment area in the working area 102, wherein the second roping down system may be coupled to the suspension element 124 such that a force-transmitting coupling may be producible between the second rope 122 and the suspension element 124. The first roping down system and the second roping down system may be designed such that the second roping down system can be roped down in the first roping down region 113 of the attachment area along a first roping length by means of the first rope 112, and such that the second roping down system can be roped down along a first roping length by means of the first rope 112, and such that the second roping down system (or the person) may be decoupleable non-destructively from the first roping down system from an end of the first roping down region, and such that the person 101 can be roped down in a second roping down region 123 along a second roping length by means of the second rope 122. In the second roping down region 123, a weight force of the person 101 may be transferable from the second rope 122 via the suspension element 124 to the attachment area.

[0080] The working area 102 may define an area, which may be at a distance to a ground and in which the person 101 may operate, for example, for mounting or maintenance. The working area 102 may, for example, represent an according area of a building, of a bridge or of a wind power plant, any of which may be located at a distance to the ground. An emergency situation may arise, for example, by a fire or another damage arising in the working area 102, which may block a way up and down (or a staircase and a leaving) from the ground to the working area 102.

[0081] The first roping down system may define a roping down system, by means of which the person 101 can rope down himself from the working area 102 along the first roping down region 113. The second roping down system may define a roping down system, in which the person 101 can rope down himself after the roping down along the first roping down region 113 along the second roping down region 123.

[0082] In the embodiment example in FIG. 1, the first rope 112 may hang from the working area 102 in the direction to the ground, such that the person 101 can rope down from the working area 102 along the first roping down region 113 in the direction to the ground. The first rope 112 may have a free end and may hang down loosely from a first attachment element 111 in the direction to the ground.

[0083] The second roping down system may have the second rope 122, along which the person 101 can rope down himself, following the first roping down region 113, along the second roping down region 123. The suspension element 124 may be attached within the working area 102 by means of a second attachment element 121. The second rope 122 may be attached to a region of the suspension element 124 that may be at a distance to the second attachment element 121. In particular, the second attachment element 121 and the second rope 122 may be attached, respectively, to ends of the suspension element 103, which ends may be opposite and mutually at a distance to one another. The second rope 122 may be attached via a third rope pulley 125 to the suspension element 124.

[0084] The suspension element 124 thus may function as a spacer element, which may put the second rope 122 at a distance from the working area 102. The suspension element 124 thus may run from the second attachment element 121 in the working area 102 out of the working area. Outside of the working area 102 and thus outside of the danger area, the second rope 122 may be attached and may hang in the direction to the ground.

[0085] A roping down device 103 may be coupled to the first rope 112 and to the second rope 122. Furthermore, the person 101 may be coupled, in particular releasably, to the roping down device 103, for example by means of a snap hook. The roping down device 103 may be designed to rope down the person 101 along the first rope 112 and the second rope 122.

[0086] As shown in FIG. 1, the roping down device 103 may be guided and/or roll along the first rope 113 as a controllable rolling wagon, including e.g. a controllable brake, in particular a centrifugal brake.

[0087] Furthermore, the roping down device 103 may be coupled to the second rope 122, without a corresponding relative movement existing between the roping down device 103 and the according attachment point with the second rope 122.

[0088] The roping down device 103 further may have a securing element, to which the person 101 may be attached.

[0089] Because the first rope 112 may be attached directly to the working area 102, in the case of a rescue operation, the person may be roped down initially along the first rope 112. The second rope 122 may be attached to the roping down device 103 and may not take over a weight force of the person 101 during the roping operation within the first roping down region 113. After the roping down along the first roping down region 113, the roping down device 103 may decouple automatically from the first rope 112, for example by the roping down device 103 sliding out of the end of the first rope 112 and the second rope 122 beginning to take over the weight force of the person 101 along the second roping down region 123. The decoupling of the roping down device 103 from the first rope 112 may be effected, in particular non-destructively, by the roping down device 103 sliding out of the end of the first rope 112.

[0090] The suspension element 123, so to say, may bridge an area and/or partially the first roping down region 113 from the working area 102 to approximately the beginning of the second rope 122. After bridging the first roping down region 113, the second rope 122 may take over the roping operation from a coupling point and/or underneath the coupling point at the suspension element 124 down to the ground.

[0091] In an emergency situation, the first rope 112 may temporarily take over the roping down function, until the person 101 may be roped down out of the danger area. Subsequently, the second rope 122 may take over the roping down function until the person 101 may have reached the ground. If the fire expands quickly within the working area 102, then the first rope 112 may be damaged speedily. However, the time, within which the first rope 112 remains stable (or resistant) to the fire, may be sufficient to rope down the person 101 out of the dangerous situation.

[0092] Subsequently, the second rope 122 may take over the roping down function. Because the second rope 122 may be coupled to the working area 102 by means of the fire-resistant suspension element 124, the second rope 122 may take over the roping down function for a sufficiently long time duration, without being exposed directly to the fire in the danger area. Because the suspension element 124 may not need to reach down to the ground, but only may have to project out of the working and/or the danger area over a specific suspension region, a low weight system having good roping functions can be provided.

[0093] In the preferred embodiment of the system 100 in FIG. 1, the roping down device 103 may be a roping wagon, which can roll off along the first rope 112 and can be braked by the person 101 or automatically/self-actuatingly. At the same time, the roping down device 103 may be fixed to the second rope 122, without a relative movement being possible between the attachment point at the second rope 122 and the roping down device 103 itself. During a roping down operation, the roping down device 103 thus may roll off along the first rope 112 and leaves the first rope 112 after the roping down along the first roping down region 113. For this purpose, the first rope 122 may have a free end, wherein the roping down device 103 can slide over and beyond along the free end in an easy manner and can be decoupled from the first rope 112. The length of the first rope 112 and/or the position of the end of the first rope 112 relative to the second rope 122 may be designed such that, after decoupling the roping down device 103 from the first rope 112, the second rope 122 may begin to take on the weight force of the person 101. Thus, no manual coupling over of the person 101 may be necessary after the roping down along the first roping down region 113 and the beginning of the second roping down region 123.

[0094] The third rope pulley 125 may be attached to the suspension element 124, wherein the second rope may be coupled to the third rope pulley 125 such that the second rope 122 can roll off from the third rope pulley 125. The third rope pulley 125 may have a rope brake, which may be configured to control a roll off of the second rope 122 from the third rope pulley 125.

[0095] FIG. 2 shows the system 100, which comprises a stowage device 203. Furthermore, the system 100 of FIG. 2 may have a carrier element 201. The first rope 112, respectively the first attachment element 111, and the suspension element 124, respectively the second attachment element 121, may be attachable to the carrier element 201, in particular at a distance from one another. The carrier element 201 may have a coupling region 202, which may be designed such that the carrier element 201 may be attachable in the working area 102 by means of the coupling region 202.

[0096] The carrier element 201 may be formed in particular from a temperature and fire resistant material, for example steel. By means of the carrier element 201, solely one attachment point to the working area 102 may be necessary. This may enable a quicker and easier attachment (fixation) of the system 100 within the working area 102. In particular, the carrier element 201 may be formed as a triangular carrier plate, wherein the first attachment element 111 may be attachable in a first corner region of the carrier plate, the second attachment element 121 may be attachable in a second corner region of the carrier plate, and the coupling region 202 of the carrier plate to the working area 102 may be formed in a third corner region of the carrier plate.

[0097] The first roping down system and the second roping down system can be arranged in the stowage device 203 such that the first roping down system and the second roping down system may be stowed in the stowage device 203 and such that the first attachment element 111 and the second attachment element 121 may be attachable in the working area 102 (for example directly, or, as represented in FIG. 2, by means of the carrier element 201). The stowage device 203 may be formed such that, upon a load to the roping down device 103, the stowage device 203 releases the first roping down system and the second roping down system.

[0098] Furthermore, the roping down device 103 may, together with a coupling region, project out of the stowage device 203, such that the person 101 can couple himself in an easy way to the system 100 and/or to the roping down device 103.

[0099] In an emergency situation, the person 101 may hang himself, for example, to the roping down device 103. Due to the weight force of the person 101, a tension may arise in the system 100, and the first roping down system and the second roping down system may leave the stowage device 203. Thereby, the stowage device 203 can be formed such that the first roping down system and the second roping down system may slide out therefrom, or such that, upon a load, the stowage device 203 may have a predetermined breaking point and/or a predetermined crack position in order to release the system 100.

[0100] FIG. 3 and FIG. 4 show a further exemplary embodiment of the system 100. The system 100 has the carrier element 201. The first attachment element 111 and the second attachment element 121 may be attached to the carrier element 201, in particular at a distance from one another. The carrier element 201 may have a coupling region 202, which may be formed such that the carrier element 201 can be attached in the working area 102, for example to a supporter in the working area 102, by means of the coupling region 202.

[0101] The suspension element 124 may be attached to the carrier element 201 by means of the second attachment element 121. The second rope 122 may be fixed, via a coupling element 306, to a region of the suspension element 124 that may be at a distance to the second attachment element 121.

[0102] Furthermore, the first rope 112 may be attached to the carrier element 201 by means of the first attachment element 111. In contrast to the exemplary embodiment of FIG. 1, there may be provided a second rope pulley 302 and a further second rope pulley 303.

[0103] The first rope 112 may be coupled to and guided by the further second rope pulley 303. The further second rope pulley 303 may have a controllable and/or self-braking rope brake, such that the further second rope pulley 303 can be rolled off with a predetermined velocity along the first rope 112 starting from the carrier element 201. For example, the further second rope pulley 303 may have a centrifugal brake, in order to roll off along the first rope 112 with a predetermined velocity.

[0104] Thereby, the first rope 112 may be able to hang down loosely or, as is represented in the exemplary embodiment in FIG. 3, may be stowed in a stowage device 307. The stowage device 307 may be fixed, for example, to the further second rope pulley 303 and may be guided therewith.

[0105] Furthermore, the second rope pulley 302 may be attached to the further second rope pulley 303 by means of a further coupling element 305. The further coupling element 305 may consist, for example, of two snap hooks that are hooked with one another. In addition or alternatively to the second rope pulley 302, further roping down systems for other rescue purposes may be coupled to the further coupling element in a modular manner.

[0106] The second rope 122 may be coupled to and guided by the second rope pulley 302. For example, the second rope pulley 302 may have a controllable and/or self-braking rope brake (e.g. a centrifugal brake), such that the second rope pulley 302 may rope down specifically the second rope 122, to which at least one person 101 to be roped down may be hooked (or hinged) to, with a predetermined velocity starting from the further second rope pulley 303.

[0107] At least the first person 101 may be attached to an end of the second rope 122. Furthermore, also a further person 301 can be fixed to the end of the second rope 122. The second rope 122 may be attached to a second rope pulley 302. Thereby, the second rope 122 may be reeled on the rope pulley 302. In the embodiment example in FIG. 3, the second rope 122 may be guided between rolls of the second rope pulley 302, wherein a section of the second rope 122, which may not be located between the persons 101, 301 to be secured and the second rope pulley 302, is stowed in a further stowage device 308, for example in a rope sack. The further stowage device 308 is fixed, for example, to the second rope pulley 302.

[0108] In the embodiment in FIG. 3, the coupling element 306 may be fixed to the further second rope pulley 303, to a further coupling element 305 or the second rope pulley 302. The coupling element 306 may, for example, a shackle (or hoop), which may enclose the suspension element 124 and which may be displaceable along the suspension element 124. An end stop 304 may be formed at a free end of the suspension element 124, wherein the end stop 304 may have a larger diameter than a pass-through-opening of the further coupling element 306, through which the suspension element 124 may be guided.

[0109] In an emergency case, the persons 101, 301 may initially secure themselves to the free end of the second rope 122. Subsequently, the persons 101, 301 to be secured may be roped down by roping down the further second rope pulley 303 along the first rope 111. Thereby, at the same time, the coupling element 306 may be guided along the suspension element 124 (see FIG. 3). After the persons 101, 301 to be secured may have roped down along the whole first roping down region 113 and, for example, the coupling element 306 may have reached the end stop 304, a force-transmitting coupling between the second rope pulley 302 and the suspension element 124 may be produced and the first rope 112 may be relieved. This relief of the first rope 112 may correspond to a non-destructive decoupling of the second roping down system from the first roping down system. Accordingly, from now on, the persons 101, 301 to be secured are roped down along the second roping down region 123 by means of the second roping element (second rope pulley) 302. Thereby, the second rope 122 may roll off from the second rope pulley 302 and/or may be guided with a defined roping velocity, until the persons 101, 301 to be secured may have roped down along the second roping down region 123 (see FIG. 4).

[0110] The suspension element 124 thus may act as a prolonged (or extended) abutment. The end stop 304 may further have a damping device (i.e. a spring-based, pneumatic-based or hydraulic-based shock absorber), such that, upon abutment of the coupling element 306 against the end stop 304, the velocity may be reduced slowly and/or the deceleration may be damped.

[0111] Furthermore, the damping device may be formed in the suspension element 124 as a load impact damping, in order to dampen the impact of the coupling element 306 on the end stop 304. The load impact damping may have, for example, a shock absorber (or band shock absorber) and/or a deformable metal part, which may be arranged between a section of the suspension element 124 and the end stop 304.

[0112] The suspension element 124 may, for example, be formed as a steel rope having an end protection and a pull-through protection (or rim hole height protection), or as an aramide rope. The suspension element 124 may have a diameter of, for example, approximately 8 millimetres.

[0113] FIG. 5 shows a further exemplary embodiment of the system 100, which has almost the same features and describes the same roping down operation as the exemplary embodiment of FIG. 3 and FIG. 4.

[0114] By contrast to the exemplary embodiment of FIG. 3 and FIG. 4, the embodiment in FIG. 5 may have a second rope 122, at an end of which the persons 101, 301 may be secured. Securing regions 501, 503 may be formed at an opposite end of the second rope 122, to which further persons to be roped down can be attached.

[0115] A roping down operation can be performed repeatedly by means of the roping down system in FIG. 5. The second rope 122 may be guided around the second rope pulley 302, wherein the respective rope ends of the second rope 122 may hang down freely.

[0116] In a first roping down operation, the persons 101, 301 to be rescued may, for example, be hanged (or hinged), for example, to a first rope end of the second rope 122, and may be roped down (see FIG. 5).

[0117] During the roping down of the persons 101, 301, the second rope end of the second rope 122 may be pulled in the direction to the second rope pulley 302. Thereby, the second rope 122 may be formed so long that, after termination of the roping operation, the securing elements 501, 502 may be pulled towards and to the second rope pulley 302.

[0118] For performing a second roping operation, the further second rope pulley 303 may be pulled along the first rope 112 in the direction to the working area 102. After the further second rope pulley 303 may have been pulled in the working area 102 and/or in the vicinity of the carrier element 201, further persons can secure themselves to the securing elements 501, 502 and rope down in the direction to the ground. Thereby, i.e. with the weight force of the persons to be roped down, the securing elements 501, 502 at the first rope end of the second rope 122 may be pulled again and anew in the direction to the second rope pulley 302.

[0119] Furthermore, the embodiment example in FIG. 5 shows exemplarily that it is also not necessary to provide a stowage device 307 and/or a further stowage device 308.

[0120] FIG. 6 shows a further exemplary embodiment of the system 100, which has almost the same features and describes the same roping down operation as the exemplary embodiments of FIG. 3 through FIG. 5.

[0121] By contrast to the systems 100 of FIG. 3 through FIG. 5, the system 100 of FIG. 6 may have a second rope pulley 302, which may rope itself down along the second rope 122 from the further second rope pulley 303 in the direction to the ground.

[0122] The second rope 122 may be coupled fixedly with one end to the further second rope pulley 303 and/or may be fixed via a further coupling element 305 to the further second rope pulley 303. In other words, there may exist no relative movement between the second rope 122 and the further second rope pulley 303.

[0123] The second rope pulley 302 may be attached via the second rope 122 to the further second rope pulley 303. In other words, the second rope pulley 302 can move relative to (or from) the further second rope pulley 303. The second rope pulley 302 may rope down, so to say, along the second rope 122 in the direction to the ground, in particular after the coupling element 306 may have reached the abutment (or end stop) 304 and the first rope 112 may be relieved and/or the second roping down system may be decoupled non-destructively from the first roping down system.

[0124] Thereby, the persons 101, 301 to be rescued may be fixed to the second rope pulley 302.

[0125] FIG. 7 and FIG. 8 show schematic representations of a further exemplary embodiment of the system 100 according to the invention, in which the first rope 112 is attached to a first rope pulley 701 and the second rope 122 can be roped down at (or from) a second rope pulley 302.

[0126] The carrier element 201 can be fixed in the working area 102. The first rope 112 may be attached to the carrier element 101 via the first rope pulley 701 at an attachment element 111. The suspension element 124 may be attached to the second attachment element 121.

[0127] The first rope 112 can be roped down from the first rope pulley 701. The first rope pulley 701 may be fixed to the carrier element 101, such that no relative movement may be provided between the first rope pulley 701 and the carrier element 101. The second criterion 302 may be fixed to an end of the first rope 112, such that no relative movement may be provided between the rope end of the first rope 112 and the second rope pulley 302.

[0128] Furthermore, the coupling element 306, which may be coupled displaceably to the suspension element 124, may be attached to the second rope pulley 302.

[0129] The second rope 122 may be reeled on the second rope pulley 302 or may be guided around the second rope pulley 302 such that the second rope pulley 302 can act as a rope brake for the second rope 122.

[0130] Corresponding securing elements 501, 502 may be provided at corresponding rope ends of the second rope 122, such that the persons 101, 301 to be rescued can be secured and/or fixed to a rope end of the second rope 122.

[0131] In addition, corresponding stowage devices 307, 308 may be provided (not shown), in order to stow the corresponding ropes 112, 122 and do not let them hang down.

[0132] During the roping operation, the second rope pulley 302 may initially be roped down from the first rope pulley 701 by means of the first rope 112, until the first roping down region 113 may have been travelled and/or until the coupling element 306 may abut against the abutment (or end stop) 304 (see FIG. 7). Subsequently, the second rope 122 and, accordingly, the persons 101, 301 secured thereto may be roped down from the second rope pulley 302, until the persons 101, 301 to be secured may have reached the ground.

[0133] During the roping down along the second roping down region 123, the weight force of the persons 101, 301 to be secured may be transferred via the second rope 122, further via the second rope pulley 302, further via the coupling element 306 and further via the suspension element 124 to the carrier plate 201. After the coupling element 306 may have reached the abutment, the second roping down system may thus be decoupled non-destructively from the first roping down system, because no substantial significant weight force of the persons 101, 301 to be secured may be transferred via the first rope 112.

[0134] FIG. 9 shows a schematic representation of a further exemplary embodiment, in which the second rope 122 may be attached to the coupling element 306, and the second rope pulley 302 may be displaceable and/or can be roped down relatively to the second rope 122. The first roping down system may be coupled with the second roping down system along the first roping down region 113. This may mean that the coupling element 306 and the second rope pulley 302 can be roped down jointly by means of the first rope 112. To this end, the first rope pulley 701 may specifically rope down the first rope 112.

[0135] After reaching the end stop 304 of the suspension element 124, the second roping down system may decouple non-destructively from the first roping down system, such that the weight force of the persons 101, 301 to be secured may be transferred from the second rope 122 via the coupling element 306 to the suspension element 124 and, accordingly, the first rope 112 may be relieved.

[0136] The coupling element 306 can be coupled with the second rope pulley 302 for example via a magnetic, mechanical and/or sensor-controlled coupling, such that a non-destructive decoupling can be performed.

[0137] Furthermore, the exemplary embodiment in FIG. 9 shows a further stowage device 308 at the second rope pulley 302, in which a section of the second rope 122 between the second rope pulley 302 and the further stowage device 308 can be stowed.

[0138] It is to be noted supplementarily, that “having” or “comprising” does not exclude other elements or steps, and that “a” or “an” does not exclude a plurality. Furthermore, it is to be noted that features or steps, which have been described with reference to one of the embodiment examples above, may also be used in combination with other features or steps of other embodiment examples described above.
