Technical area

The present invention relates to a system and method for controlled rappelling of a person in an emergency situation from a danger area or work area.

Background of the invention

In many technical fields, for example in building construction or in the installation and maintenance of wind turbines, people have to work at high altitudes. Often, access to a workspace at these high altitudes can only be achieved through a single entry and exit. In emergency situations, such as a fire, people in the work area are in great danger, especially if the fire cuts off the only entrance and exit. For external rescue workers and others

Rescue devices, such as helicopters, usually lack a sufficient rescue time.

In order to secure the entry and exit of the work area, rescue ropes are often provided at positions spaced from the entrance and exit, so that in emergency situations, the people to be rescued can be roped along these rescue ropes. The rescue ropes must on the one hand have sufficient heat and fire resistance and on the other hand be suitable to rappel the person safely from a great height on the ground.

However, there is a contradiction, since fire resistant

Rescue ropes often unsuitable properties, such as high weight and less suitable transportability, and has little suitable Abseileigenschaften. On the other hand, lightweight and suitable for rappelling rescue ropes usually have a less good

Fire resistance on.

DE 20 2014 000 428 Ul discloses a rescue device with fireproof suspension. A person to be rescued can rescue equipment along a downhill rope from a danger area are roped off once. The person is coupled via a removal device to the waste rope.

Furthermore, the removal device is attached via a connecting means to a cable clamp. The rope clamp is also attached to the downhill rope. Furthermore, the cable clamp is attached via a safety cable to a mounting area. After rappelling the person along a safety length, the cable clamp is decoupled from the removal device by destroying a predetermined breaking point, so that the power flow is transmitted from the Abfahreinrichtung via the cable clamp on the safety cable. Due to the destruction of the predetermined breaking point, the rescue device can perform a roping only once.

Presentation of the invention

It is an object of the present invention to provide a well-operated and reusable rescue system for rescuing persons from high altitudes.

This object is achieved with a system and method for controlled rappelling of a person in an emergency situation from a working space spaced from a floor according to the independent claims. According to a first aspect of the present invention, a system (so-called rappelling escape system) for controlled rappelling of a person in an emergency situation from a ground-spaced

Workspace described. The system has a first abseiling system (so-called boarding system) for abseiling the person, which can be fastened to a fastening area in the working area, the first abseiling system having a first cable for abseiling the person. Furthermore, the system has a second abseiling system (so-called.

Evacuation system) for abseiling the person, wherein the second abseiling system comprises a second cable to which the person can be coupled (directly or indirectly eg by means of a pulley or a coupling element). Furthermore, the system has a suspension element, which can be fastened to the fastening area in the working area, wherein the second abseiling system is coupled to the suspension element such that a force-transmitting coupling between the second cable and the suspension element can be produced. The first abseiling system and the second abseiling system are configured such that the second abseiling system is coupled to the first abseiling system in a first abseiling region and the second abseiling system is coupled to the first abseiling region from the attachment region along a first abseiling system

Abseillänge abseilbar by means of the first rope and the second

Abseilsystem the person is destructively decoupled from one end of the first abseiling of the first Abseilsystem and the person is abseilbar in a second Abseilbereich along a second Abseillänge with the second rope. A weight of the person is transferable in the second Abseilbereich of the second rope on the Abhängelement on the mounting area. According to another aspect of the present invention is a

Describe a method for controlled rappelling of a person in an emergency situation from a work area spaced from a floor. According to the method, a first cable of a first abseiling system for abseiling the person at a mounting area in the

Work area attached. A suspension will be on the

Attached mounting area in the work area. A second

Abseil system is coupled to the suspension element, such that a force-transmitting coupling between a second rope of the second abseiling system for abseiling the person and the suspension element can be produced. The first abseiling system and the second abseiling system are formed such that the person is roped off the attachment area along a first abseiling length with the first rope in a first abseiling area, and the person is abutted from one end of the first abseiling area in a second abseiling area along a second abseiling length second rope is roped off, wherein a weight of the person in the second Abseilbereich of the second rope on the Abhängelement is transferable to the mounting area.

The work area defines an area spaced from a floor in which the person is operating for assembly or maintenance, for example. The work area may, for example, be a correspondingly spaced-apart area of a building, a bridge or a wind turbine. An emergency situation can arise, for example, by a fire or other damage in the

Work area arise, which block entry and exit from the floor to the work area.

The first abseiling system (or the first rope) is, for example, with a first fastening element and the suspension element is fastened to the working area, for example, with a second fastening element. The fasteners are for example bolts or

Snap hooks which can be fastened to corresponding devices (for example eyelets or a corresponding bolt) in the working area. In particular, the first fastening element and / or the second fastener formed to be releasably or replaceable to be attached to corresponding devices in the work area.

The first abseiling system defines a descending system by means of which the person can abseil from the work area along the first abseiling area. The second abseiling system defines a descending system in which the person rappels within the first abseiling

Rappelling Abseilbereichs along a second Abseilbereichs. For this purpose, the first abseiling system has a first cable along which the person can abseil from the working area in the direction of the ground along the first abseiling area. The first rope may be directly within the. By means of a first fastener, for example

Work area or indirectly, as discussed below, by means of a first pulley. The first cable may also have a free end and hang loosely from the first fastener towards the ground.

The second abseiling system comprises the second rope along which the person can abseil along the second abseiling region following the first abseiling region. The person to be rescued can also be coupled relative to the second rope abseilbar / movable to the second rope or abseilbar due to a rolling of the second rope together with the second rope. The person is coupled to the second abseiling system by means of a direct coupling to the second rope or by means of an indirect coupling to a second rope pulley described below.

The first rope and the second rope are structurally separate ropes in all operating states of the system. The first rope and the second rope may have the same or different materials accordingly. The suspension element is fastened, for example, with the second fastening element within the working area. At the end of the first

Abseiling area, i. On a region of the suspension element which is at a distance from the second fastening element, the second cable is attached in a force-transmitting manner (directly or indirectly, i.e. for example by means of a coupling element described below). In particular, the second fastening element and the second cable are each attached to this force-transmitting at spaced-apart and opposite ends of the Abhängelements. The second rope can be attached to the

Abhängelement be attached either directly or by means of a coupling element described below, or by means of a pulley. The suspension element thus acts as a spacer element which separates the second cable from the working area (ie the risk area or area).

Hazardous area) spaced. The suspension element thus extends from the fastener in the work area out of the work area. Outside the work area and thus outside of the

Danger zone is attached to the second rope coupled and hangs in the direction of the ground. The attachment point of the second rope to the

Abhängelement can be fixed to one end of Abhängelements or be displaced along the Abhängelements until the

Anchor point reaches the end of the Abhängelements.

Alternatively or additionally, the first cable and / or the second cable by means of a described below in more detail pulley (or.

Cable drum), so that the abseiling device,

For example, designed as a seat belt, can be attached to the first rope and / or to the second rope without a corresponding

There is relative movement between the abseiling device and the corresponding first rope and / or second rope. Since the first rope is fastened directly in the first working area or, for example, indirectly via a first pulley or rope brake, during a rescue operation the second anchoring system with the person to be rescued is first roped off along the first rope. The second rope is attached to the abseiling device and does not receive any weight of the person during the descent within the first abseiling area. After rappelling along the first abseiling region, the abseiling device decouples automatically and non-destructively from the first rope, for example by the abseiling device sliding out of the end of the first rope, and the second rope begins to receive the person's weight force along the second abseiling region.

Non-destructive coupling is understood to mean that decoupling of the first abseiling system and the second abseiling system from each other without the destruction of coupling partners or without the provision of e.g. Predetermined breaking points is performed. Furthermore, a nondestructive decoupling means that after decoupling between the two coupling partners no power is transmitted.

For example, a force, in particular a weight force of the persons to be rescued, is transmitted in the coupled state between the first abseiling system and the second abseiling system. To

Decoupling of the first abseiling system from the second abseiling system will not transfer force between both systems. However, the first abseiling system and the second abseiling system can also have, after the decoupling of contacting elements or components, in which case no weight force is transmitted between these elements. The nondestructive decoupling can be carried out, for example, by using mechanical and / or sensor-controlled couplings or coupling elements or pulleys described below. For example, a coupling between the first abseiling system and the second abseiling system can also be implemented by means of a magnetic coupling or a mechanically or sensor-controlled switch. Due to the non-destructive decoupling of the first abseiling system from the second abseiling system, a reversible, repeatedly deployable system is provided, since no predetermined breaking point is necessary for the operation of the system according to the invention. After abseiling the person, for example, the system can be brought back into an initial state, so that another person can be roped off the work area. Thus, by repeated Abseilvorgänge a large number of people with one and the same system can be roped. This leads to an increased abseiling capacity of persons as well as to a reduction of the supply costs for such

Abseiling system, since only a system for abseiling the person must be provided to perform a variety of Abseilvorgang.

The suspension element bridges an area or the first one

Abseilbereich from the work area to about the end of the Abhängelements. After bridging the first Abseilbereichs the second rope takes over the Abseilvorgang of a crosspoint on Abhängelement to the ground. With the device according to the invention, the first cable and the second cable can be formed with a material which is preferably suitable for abseiling and has, for example, a low weight. For example, the first rope and the second rope of wire ropes, plastic fibers, Kevlar or natural fibers, especially hemp fibers are produced. For example, the first cable and / or the second cable may have an aramid sheath (or solid material) with a polyamide core. The suspension element, however, is formed with a material which has a high temperature and fire resistance.

In particular, the temperature and fire resistance of

Abhängelements higher than the temperature and fire resistance of the first rope and the second rope.

In an emergency situation, the first rope temporarily takes over the

Abseil function until the person has ridden out of the danger zone.

Subsequently, the second rope, which receives a force-transmitting coupling at a distance from the suspension element, assumes the abseiling function until the person has reached the ground. If a fire spreads quickly within the work area, the first rope is damaged quickly. However, the time in which the first rope remains resistant to the fire is sufficient to rappel the person out of the danger situation. Then the second rope takes over the abseiling function. Since the second rope is coupled to the work area by means of the fire-resistant suspension element, the second cable can have the abseiling function for a sufficiently long period of time

without being directly exposed to the fire in the danger zone. Since the suspension element does not have to extend to the ground, but only over a certain dependency area from the Arbeitsbzw. Danger zone may have a low-weight

System can be provided with good abseiling properties.

Furthermore, several people to the with the

System according to the invention, in particular on the second rope, are attached. For example, the first rope may have a length of about 2m to 20m, preferably about 10m (meter). The second rope may for example have a length of about 20m to 200m. The Abhängelement may accordingly have a length of about 2m to 20m.

According to an exemplary embodiment, the suspension element has a rail, a cable or a rope, in particular a steel cable. In addition to steel as a refractory material and aramid and / or Kevlar can be used. A rope or rod as a suspension element may have a diameter of about 5.0 mm to about 20.0 mm, preferably 10 mm (millimeters). The suspension element can also be formed by means of a refractory coating and / or with a refractory sheath. This is possible in particular, since the suspension element does not have to undertake any descent tasks.

According to an exemplary embodiment, the system comprises a rappelling device, to which the first rope and the second rope are coupled and to which the person can be coupled. The

Abseiling device is designed such that the abseiling device is movable along the first cable and / or the second cable. The abseiling device is configured to rappel along the first rope and the second rope the person. The abseiling device can either be guided along the first cable and / or the second cable as a controllable abseiling carriage (for example including a controllable brake, in particular a centrifugal brake). The abseiling device may, for example, either from the

Person himself or, for example by means of the centrifugal brake, is automatically braked.

The abseiling device may further comprise a securing element to which the person can be coupled. The fuse element

(For example, a hook, an eyelet, a closable carabiner) is designed such that the person releasably and selectively to the abseiling device can be coupled. For example, the person can move freely in the work area and quickly and easily connect to the abseiling device in the event of an emergency situation. Alternatively, the

Abseiling also be designed such that the person wearing the abseiling permanently on the body and in an emergency situation is selectively and releasably coupled to the first rope to be coupled.

In an exemplary embodiment, the abseiling device is a descending carriage, which can roll along the first cable and can be braked by the person or automatically. At the same time is the

Abseilvorrichtung fixed to the second rope, without relative movement between the attachment point on the second rope and the abseiling device itself is possible. During an abseiling process, the abseiling device thus rolls along the first rope and leaves the first rope after abseiling along the first abseiling region. For this purpose, the first rope simply have a free end, wherein the

Abseiling device in a simple manner along the free end to slide and can be decoupled non-destructively from the first cable. The length of the first cable or the position of the end of the first cable relative to the second cable is designed such that

Decoupling the abseiling device from the first rope the second rope starts transmitting the weight of the person.

With this exemplary embodiment in which the

Abseilvorrichtung along the first cable movable and thus relatively movable to the first rope and wherein the abseiling device is fixed to the attachment point on the second rope and not movably attached relative to the second rope, has the advantage that no coupling of the person after abseiling along the first abseiling area and the beginning of the second abseiling area is necessary. Thus, a so-called deadman-safe system is provided. According to a further exemplary embodiment, the first abseiling system comprises a first pulley, which by means of the first

Fastener is fastened in the work area. The first cable is coupled to the first pulley such that the first cable from the first pulley or over the first pulley is unrolled. To rappel along the first Abseilbereichs the rope is rolled, for example, to the first pulley. Furthermore, the first cable can be rolled up on the first pulley, so that during rappelling, the first rope is unrolled from the pulley.

The (first and / or second or further described second) pulley may for example have a rope brake and a

Return function (manually or by means of a return spring (eg

Spiral spring)), so that after rappelling the person the

corresponding rope can be rolled up again and thus the system can be used again.

The first rope brake can also be selectively controlled by the person. Alternatively, the first cable brake may be formed as a centrifugal brake, so that the higher the abseiling speed, the higher the braking force, so that automatically and automatically a certain speed of descent is adjustable.

According to a further exemplary embodiment, the second abseiling system has a second pulley, wherein the second pulley is coupled to the first rope such that the second pulley is abseilbar with the first rope. Furthermore, the second cable is coupled to the second pulley in such a way that the second cable can be abseilbar by means of the second pulley. The second rope pulley can be coupled directly to the first rope, in particular to a rope end of the first rope. For example, the second pulley then has no relative movement to the first rope. This means that the first rope is unwound until the second pulley has roped along the first abseiling area.

Alternatively, for example, as described below, another second pulley are coupled to the first rope, so that the second pulley is indirectly coupled to the first rope via the further second pulley.

The second pulley is coupled to the second rope, wherein the second rope is rolled up, for example, in the second pulley and is correspondingly unrolled from the second pulley.

Alternatively, the second pulley may be formed as a rope brake, so that the second pulley is threaded onto the second rope and the second rope pulley, for example, by exerting a frictional force on the second rope, the Abseilgeschwindigkeit the second rope of the second pulley itself controls. For example, the second pulley for this purpose have a centrifugal brake. Alternatively, as described below, the second cable may be attached to one end of the hanging member. In this case, the second pulley rolls along the second rope in the direction of the ground. The persons to be rescued are, for example, directly to the second

Pulley coupled.

According to a further exemplary embodiment, the second abseiling system has a further second pulley, wherein the further second pulley is connected to the first cable such that the further second pulley can be abseilbar along the first rope. The further second pulley is coupled to the second pulley. The further second pulley can be firmly connected, for example, to one end of the first rope, so that there is no relative movement between the other second pulley and the first rope. The first rope is then even roped off the work area, for example by means of the first pulley described above.

Alternatively, the first rope may be fixed in the attachment area, so that the further second rope reel was unrolled along the first rope until the end of the first abseiling area has been reached.

According to a further exemplary embodiment, the further second pulley is coupled to the second pulley such that the further second pulley is fixed to the second pulley and that the second rope is abseilbar by means of the second pulley. The fixation of the other second pulley to the second pulley causes between the other second pulley and the second pulley no relative

Movement takes place. The second pulley is then designed such that the second rope is either rolled up in the second pulley or threaded in the second pulley and the second rope is unrolled accordingly from the second pulley. In this case finds one

Relative movement between the second rope and the second pulley instead.

According to a further exemplary embodiment, the second cable is fastened to the further second cable pulley, wherein the second cable pulley is coupled to the further second cable pulley via the second cable and can be abseilbar along the second cable. This means that there is no direct fixation between the second pulley and the other second

Pulley is defined and the second pulley along the second rope of the other second pulley is foreseeable towards the ground. In this case, the persons to be rescued can be fastened, for example, directly to the second pulley. According to a further exemplary embodiment, the second abseiling system has a coupling element, wherein the coupling element is coupled to the first cable. The coupling element is further connected to the

Abhängelement coupled in such a way that the coupling element is displaceable within the first Abseilbereichs along the Abhängelements.

The coupling element may be formed for example as a bracket and encloses the suspension element completely or partially. An opening of the coupling element, through which the dependent element can be guided, has, for example, a smaller diameter than an end stop of the suspension element described below, so that such an end stop prevents the further displacement of the coupling element along the suspension element and a force-transmitting coupling between the suspension element and the coupling element is formed.

For example, in the exemplary embodiment of the present invention, the coupling element is attached directly to the first cable or indirectly by means of the further second cable pulley described above.

In other words, the coupling element may be attached to the further second pulley, so that the coupling element is coupled by means of the further second pulley to the first cable.

According to another exemplary embodiment, this is

Coupling element directly attached to the first rope.

According to another exemplary embodiment, this is

Coupling element attached to the second rope, wherein the second pulley is abseilbar along the second rope. According to a further exemplary embodiment, the

Abhängelement (eg the wire rope) at the transition between the first Abseilbereich and the second Abseilbereich an end stop, which is designed such that the coupling element is displaceable up to the end stop and can be blocked by means of the end stop. The coupling element is coupled, for example by means of a snap hook or by means of an eyelet on the suspension element. At a free end of the Abhängelements the end stop is formed, wherein the end stop has a larger diameter than z. B. has the eyelet of the second fastener.

According to another exemplary embodiment, the

End stop on a damping element which delays the displacement of the coupling element along the Abhängelement. The

Damping element may for example consist of a rubber band. In particular, when the coupling element strikes the end stop during a rappelling process, an abrupt blocking can be prevented by means of the rubber band and thus the abseiling process can be delayed by means of the damping element.

According to another exemplary embodiment, the second abseiling system comprises a third pulley fixed to the suspension element, the second rope being coupled to the third pulley such that the second rope is secured by means of the third pulley e.g. is unrollable. The third pulley may be formed according to the above-described first or second pulleys.

According to a further exemplary embodiment, the third cable pulley has a third cable brake which is arranged to engage

Rolling the second rope of the third pulley to control. The third rope brake may be formed according to the above-described first or second rope brake. According to a further exemplary embodiment, the system has a carrier element (eg a carrier plate, in particular a carrier plate)

triangular support plate). On the support element, the first fastening element and the second fastening element, in particular spaced from each other, fastened. The carrier element has a coupling region, which is designed such that the

Carrier element by means of the coupling region in the work area can be fastened.

The carrier element is in particular made of a temperature- and fire-resistant material, such as steel. By means of the carrier element only a connection point to the work area is necessary. This allows a faster and easier attachment of the system within the workspace. In particular, that can

Support member may be formed as a triangular support plate, wherein in a first corner region of the support plate, the first fastening element is attachable, in a second corner region of the support plate, the second fastening element is attachable and formed in a third corner region of the support plate of the coupling region of the support plate to the work area.

According to another exemplary embodiment, the system further comprises a stowage device. The first abseiling system and the second abseiling system can be arranged in the stowing device such that the first abseiling system and the second abseiling system in the staging system

Stowed storage device and that the first fastening element and the second fastening element can be fastened in the working area. The stowage device is designed in such a way that, when the abseiling device is loaded, the stowage device releases the first abseiling system and the second abseiling system. The stowage device can be designed, for example, as a bag or as a box or box. The stowage device is designed such that the first abseiling system, the second abseiling system and / or

For example, the abseiling of this are wrapped. The

Stowage device is designed such that the first

Fastener and / or the second fastener may protrude from the stowage device to be attached to the work area. Alternatively, the system may comprise the carrier element. In this case, only the coupling region of the carrier element protrudes out of the stowage device in order to be fastened to the work area. The stowage device can be covered with fire protection. Furthermore, the stowage device itself a

climate-proof packaging and / or a fireproof packaging. Furthermore, the stowage device can be sealed to remove e.g. to protect the interior from harmful deposits. Furthermore, a broken seal may indicate a use of the system.

Furthermore, the abseiling device can protrude out of the stowage device with a coupling region, so that the person can couple in a simple manner to the system or the abseiling device.

In an emergency situation, for example, the person hangs on to the

Abseiling device on. Due to the weight of the person tension comes into the system and the first Abseilsystem and the second Abseilsystem leave the stowage device. The stowage device can be designed such that the first abseiling system and the second abseiling system slide out or that under load

Stowage device has a predetermined breaking point or a desired tear point to release the system.

The stowage device thus offers good transportability and protection of the system. During an inactive state the system hangs in the workspace and is used by the

Stowage device wrapped and protected. Only in an emergency does the person hang himself on the abseiling device and the stowage device releases the first abseiling system and the second abseiling system.

In all the above-described embodiments of the present invention, the connections between individual components can in particular be permanently connected to each other, so that

Incorrect attachments are avoided, which can lead to a malfunction of the entire system. Especially in panic situations, mis-attachments can often be caused. In particular, the suspension element, the second pulley, the further second pulley, the coupling element and / or the further coupling element with their

corresponding coupling partners fixed and insoluble so

coupled together to avoid such mishaps. Furthermore, all the above-mentioned components (second pulley, another second pulley, suspension element, coupling element and coupling element) and the connections with each other are designed to receive or transmit a load of more than 400N (Newton), in particular more than 600N, nondestructive. By means of the invention

Systems are no breaking points necessary to ensure the functionality. As a result, the system is also possible as an irreversible system, since the system can be carried out non-destructively.

For example, the system can perform abseiling operations several times without having to exchange elements of the system.

It should be noted that embodiments of the invention have been described with reference to different subject matters. In particular, some embodiments of the invention are with

Device claims and other embodiments of the invention with method claims described. However, it will be apparent to those skilled in the art upon reading this application that, if not explicitly stated otherwise, in addition to a combination of

Characteristics belonging to a type of subject matter, also any combination of features is possible, the

different types of invention articles belong.

Abseilsystem is coupled and the second Abseilsystem in the first Abseilbereich 113 from the attachment area along a first Abseillänge by means of the first rope 112 abseilbar and the second Abseilsystem the person 101 from one end of the first Abseilbereichs from the first Abseilsystem non-destructively decoupled and the person 101st in a second abseiling region 123 can be abseilbar along a second Abseillänge with the second cable 122. A weight of the person 101 is transferable in the second Abseilbereich 123 of the second cable 122 via the suspension element 124 on the mounting area.

The work area 102 defines an area spaced from a floor in which the person 101 operates, for example, for installation or maintenance. For example, the work area 102 may be a corresponding off-the-floor area of a building, bridge, or wind turbine. An emergency situation may arise, for example, as a result of a fire or other damage occurring in the work area 102 which blocks entry and exit from the floor to the work area 102.

The first abseiling system defines a descending system by which the person 101 moves from the work area 102 along the first

Abseiling section 113 can rappel. The second abseiling system defines a descending system in which the person 101 may abseil down the first abseiling region 113 along the second abseiling region 123 after abseiling. The first cable 112 depends in the embodiment in FIG. 1 from the working area 102 in the direction of the ground, so that the person 101 moves from the working area 102 in the direction of the ground along the first floor

Abseiling section 113 can rappel. The first cable 112 has a free end and is loosely suspended from a first fastener 111 toward the floor.

The second abseiling system has the second cable 122, along which the person 101 can abseil along the second abseiling region 123 following the first abseiling region 113. The suspension element 124 is connected to a second fastening element 121 within the

Work area 102 attached. At one of the second

Fastening element 121 spaced portion of Abhängelements 124, the second cable 122 is attached. In particular, the second

Fastener 121 and the second cable 122 are each secured to spaced apart and opposite ends of Abhängelements 103. The second cable 122 is attached via a third pulley 125 to the suspension element 124.

The suspension element 124 thus acts as a spacer element which separates the second cable 122 from the working area 102. The

Abhängelement 124 thus extends from the second fastening element 121 in the work area 102 out of the work area. Outside the working area 102 and thus outside the danger area, the second cable 122 is attached and hangs in the direction of the ground.

A descender 103 is coupled to the first cable 112 and to the second cable 122. Furthermore, the person 101 is in particular detachably coupled to the abseiling device 103, for example by means of a carabiner. The abseiling device 103 is configured to abseil the person 101 along the first rope 112 and the second rope 122. The abseiling device 103 can, as shown in FIG. 1 shown as a controllable Abseilwagen including z. B. a controllable brake, in particular a centrifugal brake, along the first cable 113 are guided along or roll.

Furthermore, the abseiling device 103 is attached to the second cable 122, without a corresponding relative movement between the

Abseilvorrichtung 103 and the corresponding Ankoppelpunt with the second cable 122 is.

The abseiling device 103 further comprises a securing element, on which the person 101 is attached.

Since the first cable 112 is mounted directly in the first working area 102, in a rescue operation, the person is first rappelled along the first rope 112. The second cable 122 is attached to the abseiling device 103 and does not receive any weight of the person 101 during the abseiling operation within the first abseiling section 113. After rappelling along the first rappelling region 113, the rappelling device 103 automatically decouples from the first rope 112, for example by the rappelling device 103 sliding out of the end of the first rope 112 and the second rope 122 begins to receive the weight of the person 101 along the second rappelling region 123 , The decoupling of the abseiling device 103 from the first cable 112 takes place, in particular, in a non-destructive manner, in that the abseiling device 103 slides out of the end of the first cable 112.

The hanging element 123 bridges, as it were, an area or

partially the first Abseilbereich 113 from the work area 102 to about the beginning of the second rope 122. After bridging the first Abseilbereichs 113, the second cable 122 takes over the Abseilvorgang from a crosspoint or below the crosspoint on Abhängelement 124 to the ground.

In an emergency situation, the first cable 112 temporarily takes over the

Abseil function until the person 101 has ridden out of the danger zone. Subsequently, the second rope 122 takes over the Abseilfunktion until the person 101 has reached the ground. If a fire within the work area 102 spreads quickly, the first cable 112 is rapidly damaged. The time in which the first cable 112 remains resistant to the fire, however, is sufficient to the person 101 from the

Abseiling dangerous situation.

Subsequently, the second cable 122 assumes the abseiling function. Since the second cable 122 is coupled to the work area 102 by means of the fire-resistant suspension element 124, the second cable 122 can assume the descent function for a sufficiently long period of time without being directly exposed to the fire in the danger area. Since the Abhängelement 124 does not have to reach the ground, but only over a certain dependency from the work or

Danger zone, a low-weight system with good abseiling properties can be provided.

In the exemplary embodiment of system 100 in FIG. 1, the abseiling device 103 is a descending carriage, which can roll along the first cable 112 and can be braked by the person 101 or automatically / automatically. At the same time, the abseiling device 103 is fixed to the second cable 122 without allowing relative movement between the attachment point on the second cable 122 and the abseiling device 103 itself. During a rappel operation rolls the

Abseilvorrichtung 103 thus along the first rope 112 and leaves the first cable 112 after abseiling along the first Abseilbereichs 113. For this purpose, the first cable 122 simply has a free end, wherein the abseiling device 103 can slide in a simple manner along the free end and can be decoupled from the first cable 112. The length of the first cable 112 or the position of the end of the first cable 112 relative to the second cable 122 is such that after decoupling the abseiling device 103 from the first cable 112, the second cable 122 begins to absorb the weight of the person 101. Thus, no manual coupling of the person 101 after abseiling along the first abseiling area 113 and the beginning of the second abseiling area 123 is necessary.

The third pulley 125 is attached to the suspension element 124, wherein the second cable 122 is coupled to the third pulley 125 such that the second cable 122 is unrolled from the third pulley 125. The second pulley 125 has a rope brake which is arranged to control unwinding of the second rope 122 from the third pulley 125.

FIG. 2 shows the system 100 having a stowage device 203. Furthermore, the system 100 of FIG. 2 has a carrier element 201. On the support element 201, the first cable 112, or the first fastening element 111, and the suspension element 124, and the second fastening element 121, in particular spaced from each other, fastened. The carrier element 201 has a coupling region 202, which is designed such that the carrier element 201 can be fastened in the working region 102 by means of the coupling region 202.

The support member 201 is in particular made of a temperature and fire resistant material, such as steel. By means of the carrier element 201, only one connection point to the working area 102 is necessary. This allows a faster and easier

Attaching the system 100 within the workspace 102.

In particular, the support member 201 is formed as a triangular support plate, wherein in a first corner region of the support plate, the first Fixing element 111 can be attached, in a second corner region of the support plate, the second fastening element 121 is attachable and in a third corner region of the support plate of the coupling region 202 of the support plate is formed to the work area 102.

The first abseiling system and the second abseiling system are in the

Stowage device 203 can be arranged such that the first abseiling system and the second abseiling system are stowed in the stowage device 203 and that the first fastening element 111 and the second

Fixing element 121 in the work area 102 (for example, directly or as shown in Fig. 2 by means of the support member 201) can be fastened. The stowage device 203 is designed such that when the abseiling device 103 is loaded, the stowage device 203 releases the first abseiling system and the second abseiling system.

Furthermore, the abseiling device 103 can protrude out of the stowing device 203 with a coupling region, so that the person 101 can easily be coupled to the system 100 or the abseiling device 103.

In an emergency situation, the person 101 is attached to the abseiling device 103, for example. Due to the weight of the person 101, tension enters the system 100 and the first abseiling system and the second abseiling system leave the stowage device 203. The

Stowage device 203 may be designed such that the first abseiling system and the second abseiling system slide out or that, when loaded, the stowage device 203 has a predetermined breaking point or a predetermined tear point in order to release the system 100. FIGS. 3 and 4 show another exemplary embodiment of the system 100. The system 100 includes the support member 201. On the support member 201, the first fastening element 111 and the second fastening element 121, in particular spaced from each other, attached. The carrier element 201 has a coupling region 202, which is designed such that the carrier element 201 can be fastened by means of the coupling region 202 to the working region 102, for example to a carrier in the working region 102.

The suspension element 124 is fastened to the carrier element 201 with the second fastening element 121. At one of the second

Fastening element 121 spaced portion of Abhängelements 124, the second cable 122 is attached via a coupling element 306.

Furthermore, on the carrier element 201 by means of the first

Fixing member 111, the first cable 112 attached. In contrast to the exemplary embodiment of FIG. 1, a second pulley 302 and a further second pulley 303 are provided.

The first cable 112 is coupled to the other second pulley 303 and guided. The further second pulley 303 may be a controllable or

Have self-braking rope brake, so that the other second pulley 303 can be targeted down at a predetermined speed starting from the support member 201 along the first cable 112. For example, the further second pulley 303 has a centrifugal brake to rappel along the first rope 112 at a predetermined speed.

The first cable 112 may hang loose or, as in the exemplary embodiments in FIG. 3, in a

Stowage 307 stowed. The stowage device 307 is attached, for example, to the further second pulley 303 and carried along with it. At the other second pulley 303, the second pulley 302 is further secured by means of a further coupling element 305. The further

Coupling element 305 may for example consist of two hooked hooks hooked together. To the further coupling element, in addition to or as an alternative to the second cable pulley 302, further abseiling systems can also be coupled in a modular manner for other rescue purposes.

At the second pulley 302, the second cable 122 is coupled and guided. For example, the second pulley 302 may have a controllable or self-braking cable brake (eg, a centrifugal brake), so that the second pulley 302 targeted the second rope 122, to which at least one abzuseilende person 101 is attached, with a predetermined speed starting from the other second Rope pulley 303 rappelled.

At one end of the second cable 122 at least the first person 101 is attached. Furthermore, at the end of the second cable 122, another person 301 can be attached. The second cable 122 is attached to the second pulley 302. In this case, the second cable 122 may be rolled up on the pulley 302. In the embodiment in Fig. 3, the second cable 122 is passed between rollers of the second pulley 302, wherein a portion of the second cable 122, which is not between the persons to be secured 101, 301 and the second pulley 302, in a further storage device 308, for example, in a rope bag, stowed. The further stowing device 308 is attached to the second pulley 302, for example.

The coupling element 306 is fixed in the exemplary embodiment in FIG. 3 to the further second pulley 303, to a further coupling element 305 or the second pulley 302. The coupling element 306 is for example a bracket, which encloses the suspension element 124 and along the Abhängelements 124 is displaceable. At a free end of the suspension element 304, an end stop 304 is formed, wherein the end stop 304 has a larger diameter than a passage opening of the further coupling element 306, through which the suspension element 124 is guided.

In case of emergency, the persons 101, 301 secure first at the free end of the second cable 122. Subsequently, the persons to be secured 101, 301 are roped off by the further second pulley

306ab rutted along the first rope 111. At the same time, the coupling element 306 is guided along the suspension element 124 (see FIG. 3). After the persons to be secured 101, 301 have rappelled along the entire first abseiling 113 and example, the coupling element 306 has reached the end stop 304, a force-transmitting coupling between the second pulley 302 and the suspension element 124 is created and the first cable 112 relieved. This relief of the first cable 112 corresponds to a nondestructive

Decoupling of the second abseiling system from the first abseiling system. Accordingly, the persons 101, 301 to be secured are henceforth lowered by means of the second abseiling element 302 along the second abseiling region 123. In this case, the second cable 122 is unrolled from the second pulley 302 or guided at a defined speed abseil until the persons to be secured 101, 301 are roped along the second Abseilbereichs 123 (see Fig. 4).

The suspension element 124 thus acts as an extended stop. The end stop 304 may further include a damper (ie, a spring, pneumatic, or hydraulic shock absorber) such that upon impact of the coupler 306 against the end stop 304, the speed is slowly reduced or the deceleration is damped. The damping device may further be formed in the suspension element 124 as a shock absorption to the impact of the

Coupling element 306 to dampen the end stop 304. The

Impact damping may, for example, a strip attenuator and / or a deformable metal part, which is disposed between a region of the Abhängelements 124 and the end stop 304.

The suspension element 124 may be designed, for example, as a steel cable with end and pull-through protection or as an aramid rope. The

Abhängelement 124 may for example have a diameter of about 8 millimeters.

FIG. 5 shows another exemplary embodiment of the system 100 having nearly the same features and the same

Abseilvorgang as the exemplary embodiment of FIG. 3 and FIG. 4 describes.

In contrast to the exemplary embodiment of FIG. 3 and FIG. 4, the embodiment in FIG. 5 has a second cable 123, on which one end the persons 101, 301 are secured. At an opposite end of the second cable 122, securing areas 501, 503 are formed, to which other persons can be attached for abseiling. With the abseiling system in FIG. 5, a rappelling process can be carried out several times. The second cable 122 is guided around the second pulley 302, with the respective cable ends of the second cable 122 hanging freely. In a first abseiling process, for example, the persons to be rescued 101, 301 are hung on a first rope end of the second rope 122 and rappelled (see FIG. 5). During the descent of the persons 101, 301, the second cable end of the second cable 122 is pulled in the direction of the second pulley 302. The second cable 122 is designed so long that after completion of the Abseilvorgangs the securing elements 501, 502 were used on the second pulley 302.

In order to carry out a second abseiling process, the further second rope pulley 303 is pulled along the first rope 112 in the direction of the working area 102. After the second pulley 303 has been pulled over the working area 102 or in the vicinity of the support element 201, further persons can secure themselves to the securing elements 501, 502 and rappel in the direction of the ground. This, d .h. again with the weight of the abzuseilenden people, again

Secured elements 501, 502 at the first end of the second cable rope 122 in the direction of second pulley 302 pulled.

Furthermore, the exemplary embodiment in FIG. 5 shows by way of example that no stowage device 307 or no further stowage device 308 has to be provided.

FIG. 6 shows another exemplary embodiment of the system 100 having nearly the same features and the same rappelling operation as the exemplary embodiments of FIG. 3 to 5 describe.

In contrast to the systems 100 of FIG. 3 to 5, the system 100 of FIG. 6 has a second pulley 302 which rappels along the second rope 122 from the further second pulley 303 towards the ground. The second cable 122 is fixed at one end firmly to the further second pulley 303 or is fixed via a further coupling element 305 to the other second pulley 303. In other words, there is no relative movement between the second cable 122 and the other second pulley 303.

The second pulley 302 is attached via the second cable 122 to the further second pulley three times 3. In other words, the second pulley 302 may relatively move from the further second pulley 303. The second pulley 302 ropes, so to speak along the second rope 122 in the direction of the ground, in particular after the coupling element 306 has reached the stop 304 and the first cable 112 is relieved or the second Abseilsystem is non-destructive decoupled from the first Abseilsystem.

The persons to be rescued 101, 301 are fixed to the second pulley 302.

7 and 8 show schematic representations of a further exemplary embodiment of the system 100 according to the invention, in which the first cable 112 is fastened to a first cable pulley 701 and the second cable 122 can be lowered to a second cable pulley 302.

The support member 201 may be mounted in the work area 102. On the carrier element 101, the first cable 112 is fastened to a fastening element 111 via the first cable pulley 701. The

Abhängelement 124 is attached to the second fastening element 121. The first cable 112 is abseilbar from the first pulley 701. The first pulley 701 is fixed to the support member 101, so that no

Relative movement between the first pulley 701 and the Carrier element 101 is provided. At one end of the first cable 112, the second pulley 302 is fixed, so that no relative movement between the cable end of the first cable 112 and the second pulley 302 is provided.

On the second pulley 302, the coupling element 306 is further attached, which is slidably coupled to the suspension element 124.

The second cable 122 is rolled up on the second pulley 302 or is guided around the second pulley 302 such that the second pulley 302 can act as a rope brake for the second cable 122.

At corresponding cable ends of the second cable 122 corresponding securing elements 501, 502 are provided, so that the persons to be rescued 101, 301 can be secured or fixed to a cable end of the second cable 122.

In addition, respective stowing means 307, 308 may be provided (not shown) to stow the respective ropes 112, 122 and not to hang down.

During the abseiling process, first the second pulley 302 is lowered by means of the first rope 112 from the first pulley 701 until the first abseiling region 113 has been covered or until the

Coupling element 306 abuts against the stop 304 (see Fig. 7).

Subsequently, the second cable 122 and correspondingly the persons 101, 301 secured thereto are lowered by the second cable pulley 302 until the persons 101, 301 to be secured have reached the ground. During rappelling along the second abseiling region 123, the weight of the persons to be secured 101, 301 via the second cable 122, further on the second pulley 302, on the coupling element 306 and further transmitted via the suspension element 124 on the support plate 201. After the coupling element 106 has reached the stop 104, the second abseiling system is thus decoupled from the first abseiling system in a non-destructive manner, since no substantial weight force of the persons 101, 301 to be secured is transmitted via the first cable 112.

9 shows a schematic representation of a further exemplary embodiment in which the second cable 122 is fastened to the coupling element 306 and the second cable roller 302 is displaceable or abseilbar relative to the second cable 122. Along the first abseiling region 113, the first abseiling system is coupled to the second abseiling system. This means that the coupling element 306 and the second pulley 302 are jointly roped off by means of the first cable 112. For this purpose, the first pulley 701 can selectively rappel the first cable 112.

After reaching the end stop 304 of Abhängelements 124, the second Abseilsystem decoupled from the first Abseilsystem non-destructive, so that the weight of the persons to be secured 101, 301 is transmitted from the second cable 122 via the coupling element 306 on the Abhängelement 124 and the first cable 112th is relieved accordingly.

The coupling element 306 can with the second pulley 302, for example via a magnetic, mechanical and / or sensor-controlled

Coupling are coupled, so that a nondestructive decoupling is feasible.

Furthermore, the exemplary embodiment in FIG. 9 shows a further stowage device 308 on the second pulley 302, in which a

Area of the second cable 122 between the second pulley 302 and the further storage device 308 can be stowed. In addition, it should be noted that "encompassing" does not exclude other elements or steps, and "a" or "an" does not exclude a multitude. It should also be appreciated that features or steps described with reference to one of the above embodiments may also be used in combination with other features or steps of other embodiments described above. Reference signs in the claims are not to be considered as limiting.
