Description

[0001] The present invention relates to a rescue unit for wounded persons.

[0002] During military operations, and especially in combat, soldiers are typically wounded and must then be recovered and treated by the medical service. This involves a chain of steps that a wounded soldier may go through. This chain, or process, begins with initial treatment directly on the battlefield by a medic, also known as a medic soldier. Following this, the wounded soldier is recovered and transported, usually on a stretcher or on foot, to a casualty collection point, also called a casualty collection point or similar facility, away from the battlefield. From there, vehicles such as all-terrain ambulances, whether armored or unarmored, can typically be used to reach a military or civilian hospital.

[0003] The greatest danger from gunfire is therefore to wounded soldiers as long as they remain on the battlefield and during initial medical treatment there. Transport from the battlefield is similarly dangerous. This applies equally, or even more so, to the medics who treat wounded soldiers on the battlefield and recover or transport them away, especially carrying them or supporting them as they walk.

[0004] Regarding the dangers faced by medics as medical soldiers, it is important to note that, contrary to international law, which is supposed to offer them special protection, medics in the field or on the battlefield are specifically targeted and fired upon in order to undermine or destroy the morale of the opposing troops. Consequently, the medical corps suffers comparatively high casualties in action, contrary to international law.

[0005] One object of the present invention is to improve the protection of wounded personnel during evacuation from the battlefield. This should also be achieved, additionally or alternatively, for medics during the evacuation of wounded personnel from the battlefield. This should be possible in the simplest, safest, most flexible, and / or most cost-effective way. At the very least, an alternative to known methods should be provided.

[0006] The object of the invention is achieved by a recovery unit, a recovery container, a recovery attachment, a recovery assembly, and a trailer according to the independent claims. Advantageous embodiments are described in the dependent claims.

[0007] The present invention therefore relates to a recovery unit for wounded personnel. "Wounded personnel" refers to wounded soldiers. "Recovery of wounded personnel" refers to the recovery of wounded soldiers from the battlefield, i.e., from combat and thus from under fire and the like.

[0008] The recovery unit has a frame with a chassis, which allows it to move in one direction on a surface. The direction of travel corresponds to the forward movement, i.e., the movement of the recovery unit forward. It can also move backward, i.e., in the opposite direction. The direction of travel lies along the longitudinal axis, meaning it points forward along the longitudinal axis of the recovery unit.

[0009] The terrain may be particularly unpaved and uneven, especially on a battlefield. Accordingly, the chassis may preferably be designed for off-road use, which can be achieved by means of appropriate wheels and suspension and / or by means of a tracked undercarriage, and in particular by means of an armored tracked undercarriage.

[0010] The rescue unit also includes a rescue container designed to accommodate at least one wounded person, preferably several wounded persons lying horizontally side by side, or to accommodate goods using a load carrier designed to carry them. Thus, the rescue unit according to the invention also includes a container for accommodating and transporting at least one wounded person or soldier. This can preferably be done for several, in particular exactly two, wounded persons lying side by side, in order to be able to rescue more wounded persons at once and therefore more quickly. Alternatively, a load carrier can be used instead of such a rescue container to carry loads, goods, or merchandise. In any case, the wounded person can be transported using the rescue container, or the goods using the load carrier, in this manner.They can be made mobile, as will be described in more detail below. The recovery container and / or the load carrier can be armored, particularly with regard to their outward-facing surfaces such as side walls, end faces, bottom and / or roof, to increase protection.

[0011] The aforementioned frame is designed to accommodate the recovery container or load carrier along its vertical axis as a transport position. Thus, the recovery container or load carrier can be transported or moved by the frame with its chassis as a vehicle. This allows the empty recovery container to be transported to a wounded person, i.e., to the location where a wounded person is situated, so that the wounded person can be picked up from the recovery container, as will be described in more detail below. The vehicle or frame with its chassis can then move the recovery container with the wounded person inside, particularly away from the battlefield, to an ambulance, a casualty collection point, or similar location. Likewise, goods can be transported from the vehicle to a location, particularly outside the battlefield, using the load carrier.outside a danger zone, to another location, especially on the battlefield or within a danger zone, where it is handed over by the carrier or taken from the carrier by persons, and the partially or completely emptied carrier is then moved away again, back off the battlefield or out of the danger zone.

[0012] In every case, the rescue unit has a crane designed to swing perpendicular to the direction of travel over the frame in order to pivot the rescue container or load carrier back and forth between the transport position and a lowered position to the side of the frame. This allows the previously mentioned possibility of the wounded person reaching the rescue container or the goods being removed from the load carrier to be implemented.

[0013] In this context, such a crane is generally understood to be any type of movable, driven element capable of lowering a recovery container or load carrier from above onto the chassis (which together can be referred to as a vehicle or formed by a vehicle), laterally, i.e., perpendicular to the direction of travel, perpendicular to the longitudinal axis of the vehicle, or along the transverse axis of the vehicle, next to the chassis, whether directly onto the same surface on which the vehicle or the chassis of the recovery unit is moving, or which is elevated or lower than the surface, for example, in a bomb crater or a trench. The swiveling of the recovery unit's crane thus generally implies a movement of the recovery unit or load carrier from its transport position.to be understood as moving upwards from the frame, then sideways and then downwards next to the vehicle, whereby these directions of movement or this sequence of movements can also be combined, i.e. diagonally or arc-shaped.

[0014] This can preferably be accomplished using a crane similar to a skip loader, where, in this analogy, the recovery container or load carrier corresponds to a skip container. This allows the previously described movement, comparable to the placement and retrieval of a skip container using a skip loader, to preferably be arc-shaped, which can be considered a continuous pivoting motion. The crane of the recovery unit according to the invention can additionally have cables to vertically lift and lower the recovery container or load carrier, preferably with the crane stationary and pivoted above the frame. The pivoting motion of the crane can be implemented with any suitable drive, such as pneumatic or hydraulic cylinders or electric drives, which can effect the pivoting of the crane directly via rotation or indirectly via translation.

[0015] In any case, the present invention is based on the understanding that, until now, the recovery of wounded personnel from danger zones, particularly from the battlefield, has been carried out by medics or other soldiers. This has typically been done using stretchers, which require two people to carry while walking more or less upright. These individuals are thus tied up and unavailable for other tasks for the duration of the recovery operation. Furthermore, these individuals expose themselves to an increased risk of fire on the battlefield. It should be noted that, contrary to international law, medics are often targeted and therefore particularly vulnerable during recovery operations.

[0016] According to the invention, the wounded person can thus be transported out of the danger zone or off the battlefield relatively quickly using the vehicle, i.e., the frame with chassis of the rescue unit according to the invention, and, if necessary, protected by the rescue container and / or by the contour or frame of the vehicle. Furthermore, other persons, and in particular medics, i.e., medical soldiers, can be relieved of the task of rescue and instead concentrate on providing initial care to the wounded person and, if necessary, moving the wounded person into the rescue container. This can be done by the medics while lying down or kneeling, and thus relatively protected, especially by the contour of the frame with chassis of the rescue unit. Likewise, supplies can be delivered without the use of personnel.

[0017] In any case, this eliminates the need for personnel outside the recovery unit, thus relieving and protecting individuals from these tasks by keeping them off the battlefield or allowing them to remain relatively safe there. Accordingly, a person can be present as the driver or operator of the recovery unit, specifically sitting in the vehicle's cab and handling both driving and crane operation without having to leave the cab during the operation. Preferably, the recovery unit can be operated entirely without personnel by remotely controlling the vehicle as an unmanned vehicle from a safe distance or location.

[0018] Of particular preference is the possibility of designing the vehicle or vehicle component of the rescue unit according to the invention as an unmanned ground vehicle (UGV) capable of operating independently, by providing the unmanned vehicle with appropriate sensors, a control unit, and the like, in order to automatically and autonomously reach the injured person and transport them to a specific location, as will be described in more detail below. In any case, the vehicle is preferably a land vehicle.

[0019] A stretcher may be used to recover the wounded, i.e., to place the wounded person on the stretcher and then move them, particularly into the rescue unit and during transport with the rescue unit. In this case, the stretcher may preferably be equipped with an air mattress or air cushion on which the wounded person can be placed for gentle transport.

[0020] According to one aspect of the invention, the crane is further designed to pivot upwards along the vertical axis above the frame and to raise and lower the recovery container or load carrier along the vertical axis relative to the frame. This can increase the movement options of the recovery unit or load carrier. This allows a sequence of movements, as previously mentioned, to be implemented by first pivoting the crane upwards, particularly from a position below the top of the received recovery container or load carrier, and especially from a position lying flat on the frame, upwards above the recovery container or load carrier, particularly along the transverse axis or perpendicular to the direction of travel or centrally to the longitudinal axis, in order, for example, to tension the cables in a straight line between the recovery container or load carrier and then to lift the recovery container or load carrier.The crane lifts the load carrier in a straight line, without any lateral pendulum or swinging movements. It can then be swivelled further to move the recovery container or load carrier laterally beyond the outline of the frame or vehicle and lower it onto the ground next to the vehicle, or to a higher or lowered position, using the cables.

[0021] Chains or similar devices can be used instead of ropes. Translational drives, such as pneumatic or hydraulic cylinders or linear actuators, can also be used to achieve the previously described relative movement between the crane and the recovery unit or load carrier.

[0022] According to a further aspect of the invention, the crane is arranged perpendicular to the direction of travel at the edge of the frame. Thus, the crane's pivot axis runs along the longitudinal axis, i.e., in the direction of travel of the vehicle, but along the transverse axis, i.e., perpendicular to the longitudinal axis, i.e., the direction of travel, offset towards the edge of the frame relative to the center. The crane can therefore reach its highest position precisely at the edge of the frame during its pivoting movement, which can simplify lifting the recovery unit or load carrier beyond the frame's contour. This can also maximize the crane's range of motion if the crane has a pair of pivoting arms as pivotable elements, as will be described in more detail below. These arms are then designed as a single piece, i.e., with a fixed length, and can reach a maximum height when pivoting without collapsing in the lowered or raised position.The item, when placed on the frame, should protrude beyond the contour of the frame on the opposite side along the transverse axis, which can improve the compactness of the recovery unit or the vehicle with crane.

[0023] According to a further aspect of the invention, the crane, preferably of a fixed length, is designed to be arranged perpendicular to the direction of travel within the dimensions of the frame in the transport position of the recovery container or load carrier. This can be done as described above and brings with it the corresponding properties and advantages.

[0024] According to a further aspect of the invention, the crane is designed to be positioned lower than the recovery container or load carrier along the vertical axis in the transport position, preferably lying flat on the frame. This can promote the compactness of the recovery unit and, in particular, ensure the flattest possible contour. This can be especially advantageous for movement in rough terrain, such as in a forest, to minimize collisions with branches and the like.

[0025] According to a further aspect of the invention, the crane has a pair of pivot arms designed to pivot together perpendicularly over the frame in the direction of travel, wherein the pivot arms and the recovery container or load carrier are designed such that the pivot arms are arranged in front of and behind the recovery container or load carrier in the direction of travel. This can represent a concrete implementation possibility, as mentioned previously. In particular, this can enable movement comparable to that of a tipper truck, as previously described.

[0026] According to a further aspect of the invention, the crane has a drum bar which connects the two swivel arms, preferably their ends furthest from the frame, in the direction of travel, wherein the drum bar has a pair of rope drums, each configured to wind and unwind a rope in order to lower and raise the recovery container or load carrier along the vertical axis, wherein the rope drums are preferably designed to be rotaryally driven. This can represent a concrete way of implementing the corresponding properties and advantages as already mentioned.

[0027] According to a further aspect of the invention, the drum rod is rotatably mounted on one of the two pivot arms by means of a rod bearing, wherein a drum drive is arranged on one of the two pivot arms and connected to the drum rod on the output side in order to drive the drum rod rotationally. This can represent a concrete implementation possibility that can be comparatively simple and robust.

[0028] According to a further aspect of the invention, the crane has a crossbeam which connects the two slewing arms, preferably their ends facing the frame, in the direction of travel, the crossbeam being rotatably connected to the frame by means of a pair of bearing elements. The crossbeam thus connects the two slewing arms, enabling them to pivot back and forth together and synchronously. Therefore, a single drive can be sufficient to move the pair of slewing arms together. The crossbeam can also improve or increase the stability of the crane.

[0029] According to a further aspect of the invention, the crane has at least, preferably exactly, a slewing drive configured to move a rack translationally perpendicular to the direction of travel, preferably by means of a ball screw drive, wherein the slewing arm, preferably at its end facing the frame, has a gear which engages with the rack of the slewing drive. This can represent a concrete way of implementing a drive to move the crane or its slewing arms.

[0030] According to a further aspect of the invention, the recovery unit also includes at least one damping element, which is arranged between the frame and one of the two swivel arms and is designed to absorb a portion of the crane's static load when the crane is swung over the frame. This can relieve the crane of this load or weight, allowing the crane's drive to be designed with a lower power output. A gas spring, preferably in pairs for the two swivel arms of the crane, can be implemented as such a damping element. The gas spring can act as a damping element directly between the frame and the crane, or indirectly by connecting the gas spring to the crane via a cable or a similarly acting element, preferably a pulley system, as will be described in more detail below.

[0031] According to a further aspect of the invention, the damping element comprises a tension element, preferably a cable, which connects the swivel arm to a gas spring in a force-transmitting manner. This can represent a concrete implementation possibility, as already mentioned.

[0032] According to a further aspect of the invention, the damping element also comprises a deflection element, preferably a deflection pulley, which is arranged perpendicular to the direction of travel, opposite the crane, preferably opposite a bearing element of the crane, on the frame, preferably at the edge of the frame. Thus, a pulley mechanism can be implemented by means of the damping element to transmit and absorb higher forces.

[0033] According to a further aspect of the invention, the recovery unit has at least, preferably exactly, an extendable counterweight, which is designed to be extended perpendicular to the direction of travel and opposite to the slewing direction of the crane beyond the frame in order to at least compensate for the weight of the empty recovery container or the empty load carrier in the lowered position. This allows the moment about the longitudinal axis of the vehicle or the frame with chassis of the recovery unit to be at least partially compensated, which is generated by the recovery container or the load carrier if it has swung beyond the contour of the frame. This can increase the stability of the recovery unit when the recovery container or the load carrier is located laterally outside the contour of the frame or the vehicle. The counterweight can preferably be continuously adjustable.The counterweight is continuously extended and retracted to such an extent that, at every point during the crane's slewing motion, the moment of the laterally projecting rescue container or load carrier around the longitudinal axis of the vehicle or the frame with the chassis of the rescue unit is balanced as precisely as possible. This can preferably also be done taking into account the additional weight of the casualty(s) held in the rescue container or the goods held by the load carrier, thereby further improving the stabilizing effect of the extendable and retractable counterweight.

[0034] According to a further aspect of the invention, the extendable counterweight comprises a weight element whose weight corresponds at least to that of the empty rescue container or the empty load carrier, wherein the weight element can be extended and retracted relative to the frame perpendicular to the direction of travel by means of at least one thrust drive. This can represent a simple yet effective way of implementing the previously described concept, since fixed values ​​or constant specifications of the loads or moments to be balanced by the counterweight can be used to determine when and how far the counterweight must be extended or retracted along the transverse axis, thus minimizing the implementation effort. This can also be sufficient to essentially achieve the desired increased stability as previously described, even if the weight of the rescue container is greater than the weight of the wounded person(s).the weight of the load carrier is greater than the weight of the goods.

[0035] According to a further aspect of the invention, the extendable counterweight, preferably its weight element, has armor plating, preferably being designed as armor plating. This allows the extendable counterweight to simultaneously serve as lateral protection. This can be particularly advantageous on this side of the frame with chassis or the vehicle, because the side with the extendable counterweight, during the rescue of a wounded person or when unloading goods, faces away from precisely that side of the frame with chassis or the vehicle and is thus oriented towards the direction from which fire is expected, which can be effectively deflected by the armor plating.

[0036] According to a further aspect of the invention, a deflector, preferably rising from the frame in the opposite direction of travel, is arranged in the direction of travel in front of the recovery container or the load carrier in the transport position, in order to at least partially, preferably completely, adapt the contour of the frame to the height of the recovery container or the load carrier in the transport position. Thus, the deflector is arranged on or attached to the frame or vehicle, aligned, and shaped with respect to its contour so that, when the recovery unit moves forward in the direction of travel, branches and the like can be lifted or bent by the deflector along the vertical axis to be guided over the frame or vehicle and subsequently over the recovery container or load carrier in the transport position. This can be achieved in particular by means of a deflector that is triangular in longitudinal section.

[0037] According to a further aspect of the invention, the frame has a receiving space, preferably cuboid in shape, into which the recovery container or load carrier can be lowered along the vertical axis for transport. Thus, the recovery container or load carrier can be partially or sectionally received along the vertical axis within the lateral contour of the frame or vehicle, so that only the remaining portion protrudes upwards. This reduces the height of the recovery unit with the recovery container or load carrier in place, which in turn reduces the visibility of the recovery unit on the battlefield and thus the risk of being hit by fire. Furthermore, this can increase maneuverability in the terrain by lowering the center of gravity of the recovery unit and / or by reducing the risk of collisions with branches and the like.

[0038] According to another aspect of the invention, the frame with the chassis is part of a, preferably unmanned, vehicle and the crane is part of a recovery attachment, wherein the recovery attachment has a frame which is connected to a frame of the vehicle.

[0039] In other words, the previously described recovery unit is not only a combination of frame and crane together with the recovery container or load carrier that is movable or detachable and separable relative to it, but rather the frame with chassis as a vehicle and the crane can also be designed separately and combined by the arrangement or by mounting the recovery attachment with crane on the frame of the vehicle as described above.

[0040] This separate design of the vehicle and the recovery attachment makes it possible to retrofit or further develop a known or commercially available suitable vehicle, such as an unmanned land vehicle as previously described, with a recovery attachment with a crane according to the invention, thus creating the recovery unit described above. The same recovery attachment, possibly with modifications to brackets and the like, or using adapters, can also be used on different vehicles, and especially on different unmanned land vehicles, to retrofit each of them into a recovery unit according to the invention. Furthermore, such vehicles, and especially unmanned land vehicles, can also be used in ways other than with the recovery attachment according to the invention in order to increase or expand their range of applications.The recovery attachment according to the invention can be adapted to different vehicles relatively easily and cost-effectively by making structural adjustments to the recovery attachment and, in particular, its frame.

[0041] According to a further aspect of the invention, the frame of the recovery attachment has a bracket, preferably cuboid in shape, the contour of which corresponds to the receiving space of the vehicle's frame, preferably cuboid in shape, so that the bracket of the recovery attachment frame is at least positively engaged with and held by the receiving space of the vehicle's frame. The bracket of the recovery attachment frame is designed so that the recovery container or load carrier can be lowered into the bracket of the recovery attachment frame along the vertical axis as a transport position. This can provide a way to arrange or mount the recovery attachment on the vehicle simply, quickly, and yet securely in a positively engaged manner.

[0042] Such a rectangular or cuboid shape or contour can facilitate a positive fit as a connection. Furthermore, such a rectangular or cuboid receiving space, or the corresponding interior of the recovery attachment's mounting, can accommodate the recovery container or load carrier in a space-saving manner, particularly with a corresponding rectangular or cuboid contour. This can also facilitate a positive fit of the recovery container or load carrier within the rectangular or cuboid receiving space, or the corresponding interior of the recovery attachment's mounting.

[0043] According to a further aspect of the invention, the frame of the recovery attachment is connected to the vehicle frame at least along the vertical axis by means of at least one damping element, preferably resting on the vehicle frame. Preferably, several damping elements are distributed horizontally, preferably at the corners of the recovery attachment frame. Any type of suitable vibration damper can be used as damping elements, in particular, the simplest, most robust, and / or most compact types of vibration dampers. These can preferably be rubber elements or rubber-metal elements. Hydraulic or pneumatic vibration dampers can also be used.In any case, the rescue container, especially with a wounded person inside, or the load carrier, especially with goods inside, can be transported in this way with vibration damping, especially on rough terrain such as in open country or on the battlefield, which can be particularly gentle on the wounded person inside or on the goods inside.

[0044] According to a further aspect of the invention, the rescue container has at least one hinged side wall, preferably two hinged side walls, which preferably correspond to the length of a stretcher and / or the height of a stretcher with a wounded person lying on it, wherein the side wall preferably has a window corresponding to the position of the head of a wounded person lying on a stretcher. One or two side walls can provide protection for the interior or the wounded person contained therein from external influences such as weather, in particular wind, rain, snow, and the like. Depending on the design and, if necessary, by means of armor plating, protection of the wounded person contained therein from gunfire or at least from explosions can also be achieved.

[0045] By means of the hinged side panel(s), positioned opposite each other along the transverse axis or perpendicular to the direction of travel or longitudinal axis, access to the interior of the recovery container for the wounded can be provided, allowing the wounded person, preferably lying on a stretcher, to be moved in and out again. This side access can be particularly useful on the battlefield or in the danger zone for the medic treating the wounded, enabling them to move or lift the wounded person, especially lying on a stretcher, into the interior of the recovery container.

[0046] The side wall can preferably be opened downwards onto the ground to provide a base onto which the stretcher can be moved and placed from inside the rescue container in order to move the wounded person onto the stretcher.

[0047] With regard to the height of the side wall and preferably of the rescue container as a whole, at least in its essentials, it may be advantageous if the wounded person lying on the stretcher can be moved into the rescue container by the medic without barriers in terms of height and length, so that a correspondingly high and long hinged side wall may be particularly suitable for this purpose or may make this possible.

[0048] Providing a window in the side wall, or in each side wall, where the wounded person's head is located, can allow the wounded person to look out of the rescue container, thus avoiding the oppressive impression of a closed rescue container.

[0049] According to a further aspect of the invention, the recovery container has at least one hinged end face, preferably two hinged end faces, which preferably correspond to the width of a stretcher and / or the height of a stretcher with a wounded person lying on it, wherein the end face preferably has a window corresponding at least to the position of the head of a wounded person lying on a stretcher. This can make it possible to apply the corresponding properties and advantages previously described with reference to the side wall to the end face(s) of the recovery container in a comparable manner. In particular, removal along the longitudinal axis outside the battlefield or outside the danger zone can be carried out via the end face by inserting the stretcher handles through the opening formed by the hinged or hinged end face.The folded-down front surface allows access to quickly pull the wounded person out of the rescue container.

[0050] According to a further aspect of the invention, the rescue container has a roof, wherein the roof preferably has a window corresponding to the position of the head of a wounded person lying on a stretcher, and / or wherein the roof preferably has a pair of rope attachments, preferably spaced apart from each other along the direction of travel and / or arranged in a straight line to each other along the direction of travel, which are designed to be connected to a crane rope. The roof of the rescue container can provide protection from above for the interior or for the wounded person contained therein, as previously described. A window arranged there can offer the corresponding advantages and properties, as also previously described.

[0051] Attaching the previously described ropes or similar lifting devices to the roof of the recovery container using specially designed means in the form of rope fixings can be one way to connect the ropes, and in particular their ends, to the recovery container in such a way that the recovery container can be raised and lowered using the ropes or the like. The corresponding preferred arrangements can facilitate moving, lowering, and raising the roof or the recovery container as a whole while maintaining a stable horizontal orientation.

[0052] According to a further aspect of the invention, the recovery container has feet to stand on the ground, and / or skids to be moved across the ground. Each of these features provides stable and defined contact with the ground. The feet can serve as the point of contact, ensuring that a lowered position is maintained as securely as possible. The skids additionally allow the recovery container to be moved across the ground in one direction, preferably in the direction of travel or along the longitudinal axis of the vehicle, i.e., pulled or pushed. Furthermore, due to their comparatively large horizontal surface area, the skids can prevent or at least reduce sinking into the ground, for example, in damp or rain-soaked soil.

[0053] According to a further aspect of the invention, the rescue container has a bottom which is designed, preferably with feet or skids, to be placed on the ground along the vertical axis, wherein the bottom is designed to face away from the ground along the vertical axis, to accommodate at least the wounded person lying down, preferably several wounded persons lying down next to each other horizontally, directly and / or on a stretcher.

[0054] This allows the rescue container to be sealed at the bottom, providing additional protection as previously described. The base can also serve as a connection point for the feet and / or skids to the rest of the rescue container, as well as providing a support for the wounded person, particularly on a stretcher.

[0055] According to a further aspect of the invention, the base, along the vertical axis facing away from the ground, has at least one pair of stretcher guides, preferably one pair per stretcher, to guide the stretcher in the direction of travel and / or perpendicular to the direction of travel and to hold it in a position deviating from this direction, wherein preferably the pair of stretcher guides runs only in the direction of travel. This can enable defined guidance of the stretchers upon contact with the base of the recovery container. Implementing this preferably in the preferred directions can enable guidance of the stretchers in precisely these directions, corresponding to the previously described hinged side wall and / or front surface. In particular, the stretcher guides can be limited to guiding the stretcher along the longitudinal axis and thus in the direction of travel, which facilitates removal of the stretchers via the front surface for the removal of the wounded person outside the battlefield.can accelerate.

[0056] According to a further aspect of the invention, the rescue container has a tub element and a lid element, which are designed to jointly accommodate the wounded, preferably several wounded lying horizontally next to each other, wherein the tub element and the lid element are designed to be connectable and separable from each other, and wherein the lid element is designed to be lifted from the tub element by the crane and lowered onto the tub element.

[0057] Thus, the recovery container can also be designed in two parts, with the recovery container having and preferably consisting of a tub element and a lid element, which can be connected in order to be moved or handled as a single unit, and which can be separated without damage in order to better access the interior of the recovery container.

[0058] Accordingly, the entire rescue unit can be lowered by crane onto the ground, as previously described. Then, a paramedic on site can disconnect the tub and lid, allowing the lid to be lifted while the tub remains on the ground. The paramedic can then transfer the injured person onto the tub or a stretcher positioned there, after which the lid can be lowered back onto the tub to close the interior of the rescue container. Finally, the paramedic can reconnect the tub and lid from the outside, allowing the lid to be lifted, and thus the entire rescue container lifted from the ground and moved or swung onto the vehicle, as previously described.This can improve the possibilities of accessing the interior of the recovery container, compared to hinged side walls and / or front surfaces, as previously described.

[0059] According to another aspect of the invention, the tub element has a bottom and the lid element has a pair of side walls, a pair of end faces and a roof. This can represent a concrete way of implementing the invention as previously described.

[0060] According to a further aspect of the invention, the tub element has at least one, preferably exactly one, centering element at some, preferably all, corners, preferably at the bottom, which are designed to jointly guide the lid element when lowered onto the tub element, wherein the centering elements are preferably designed as inclined projections inclined away from the edge of the tub element. This can enable automatic alignment of the lid element with respect to the tub element standing on the base or the like when the lid element is lowered, by increasingly restricting the lateral movement of the lid element relative to the tub element in the horizontal plane as the lid element is lowered further towards the tub element, until finally the edge of the lid element rests precisely on the tub element.there, against the tub element, so that the connection between the tub element and the lid element of the recovery container can be established, as previously described.

[0061] According to a further aspect of the invention, at least one light source is arranged within the lid element, preferably oriented towards the tub element, and / or the lid element has at least one camera, preferably oriented towards the tub element. Each of these features, and particularly the combination thereof, can improve the lowering of the lid element onto the tub element, as an operator of the vehicle and crane, whether seated in the vehicle or remotely via remote control of the unmanned vehicle, can see the interior of the rescue container in the form of the lid element spaced apart from the tub element and thus lower the lid element onto the tub element more effectively and safely for the injured person inside. This can also be achieved by means of an automated control system of an unmanned, autonomously driving and operating vehicle.

[0062] The present invention also relates to a rescue container for use in a rescue unit as described above, which is designed to accommodate at least one wounded person, preferably several wounded persons, lying horizontally side by side. This provides a suitable rescue container for implementing a rescue unit as described above and for utilizing its properties and advantages.

[0063] The present invention further relates to a recovery attachment for use with a, preferably unmanned, vehicle and a recovery container as described above, as a recovery unit as described above, wherein the recovery attachment has a frame for being connected to a frame of the vehicle, and wherein the recovery attachment includes at least the crane. This makes it possible to provide a suitable recovery attachment for implementing a recovery unit as described above, i.e., to further develop a suitable vehicle, and in particular an unmanned vehicle, by means of the recovery attachment, and to utilize its features and advantages.

[0064] The present invention further relates to a recovery system comprising a recovery unit as previously described, wherein the recovery unit, preferably the frame of the recovery unit, has a trailer coupling, and a trailer which is pivotably connected in the direction of travel to the trailer coupling of the recovery unit by means of a trailer coupling, wherein the trailer is connected, preferably wirelessly, to the recovery unit, preferably to its vehicle, transmitting data, and wherein the trailer has a control unit which is configured to control the recovery unit, preferably its vehicle.

[0065] In this way, the vehicle of the previously described recovery unit can be used as a towing vehicle of a vehicle combination according to the invention, by having a trailer according to the invention with a control unit for controlling or steering the recovery unit, to which the trailer is connected like the trailer of a truck and trailer combination. This can make it possible to use the previously described recovery unit as a towing vehicle. The trailer can have at least one door, flap, and / or hatch as an access point to the interior. A wireless connection can eliminate the need for the corresponding wiring between the trailer and the vehicle of the recovery unit, which can save effort. Furthermore, a wired connection, especially in rough terrain, can be damaged or interrupted, which cannot be the case with a wireless connection. The trailer can have a frame, a chassis, or...a chassis with a running gear, preferably with wheels, to be pulled or pushed on the ground or its surface and thus moved by means of the running gear or its wheels.

[0066] According to one aspect of the invention, the trailer is designed to accommodate at least one wounded person, preferably several wounded persons lying horizontally side by side. This increases the possibilities and capacities for transporting wounded persons. The previously described options of fold-out side walls and / or end panels can also be used here to accommodate the wounded person, and in particular the wounded persons lying horizontally side by side, inside the trailer. This can be done from the rear by means of fold-out or fold-down end panels on a stretcher, preferably while the person carrying the stretcher and moving it into the interior of the trailer is standing. Accordingly, the trailer can be...The rescue team is more likely to be deployed in hazardous areas with protective buildings, in order to then travel across open terrain to a safe place for further care of the wounded.

[0067] According to a further aspect of the invention, the trailer has a lifting / lowering device designed to lower and raise the part of the trailer intended for receiving the wounded person relative to a frame, preferably with a chassis, of the trailer along the vertical axis as a vertical lifting movement. Thus, the part of the trailer that can receive the wounded person(s) can be lowered to the ground, making the interior of this part of the trailer more easily accessible to the wounded person or the paramedic providing care, particularly when the wounded person and / or the paramedic are kneeling or lying down. This can improve the protection of both the wounded person and the paramedic. The part of the trailer intended for receiving the wounded person can also be referred to as a cabin, which is positioned relative to the frame or chassis.The chassis can be raised and lowered vertically. The operator's station or driver's seat for the trailer or recovery vehicle can also be located in this cabin.

[0068] The fact that the lifting / lowering device has at least one, preferably hydraulic, lifting cylinder to perform the vertical lifting movement can represent a concrete way of implementing the required force.

[0069] Preferably, the lifting / lowering device comprises at least one pair of lifting cylinders, preferably hydraulic, arranged opposite each other along the longitudinal or transverse axis and facing away from the part of the trailer designed to accommodate the wounded person. This allows for vertical movement on both sides of the cabin, enabling the cabin to be raised and lowered evenly and without tilting relative to the frame.

[0070] According to a further aspect of the invention, the trailer, preferably a rear wall, has at least one closable opening designed so that a stretcher with the wounded person can be pushed through the open opening into and pulled out of the trailer's interior. This can represent a concrete way of implementing this function of the trailer.

[0071] Preferably, the trailer has an extension / retraction mechanism designed to be extended, preferably along the longitudinal axis opposite to the direction of travel, from the part of the trailer intended for receiving the wounded person, in order to receive the wounded person, preferably on a stretcher. The extension / retraction mechanism can be passive, for example, comparable to a drawer mechanism, to allow movement in the respective horizontal direction, in particular to flexibly receive the stretcher, thus facilitating the loading and unloading of the wounded person, especially on a stretcher. Alternatively, the extension / retraction mechanism can be active, i.e., driven, to be operated by means of at least one drive mechanism.whose motor can be extended and retracted horizontally in the respective direction, which can relieve the wounded person and the paramedic of this effort and save time.

[0072] Preferably, the extension / retraction mechanism passes through the open passage in the rear wall. This can enable a combined use of the corresponding features and advantages of the present invention as described above.

[0073] According to another aspect of the invention, the trailer is designed to be as high along the vertical axis between a floor and a roof as a wounded person lying on a stretcher, preferably. In other words, the trailer or its cabin can be designed to be as low as possible to make it harder to see and shoot at, thus increasing protection. At the same time, the trailer or its cabin is sufficiently high to provide enough space along the vertical axis for the wounded person lying down, and possibly for their stretcher. The comparatively low height of the trailer or its cabin also reduces the weight that the trailer has to move.

[0074] According to a further aspect of the invention, the trailer has a driver's cab, preferably made of glass, which extends above the roof along the vertical axis. This allows the driver of the trailer or the recovery vehicle to sit upright in order to operate and drive the trailer or the recovery vehicle. At the same time, the driver's cab can also be designed to be as low-profile as possible to reduce visibility and make it harder to shoot at, which can also increase protection. The driver's cab can have sufficient windows, preferably in all horizontal directions, to give the driver an adequate view of the surroundings. Constructing the driver's cab entirely of glass, i.e., made of glass, can provide a continuous all-around view as well as an upward view along the vertical axis. The glass of the driver's cab can preferably be made of bullet-resistant or...The cab should be constructed with bulletproof glass to increase driver protection. It may be designed to swivel or fold to the side to allow for entry and exit.

[0075] According to a further aspect of the invention, the trailer has a roof with an opening designed to allow a person to access the interior of the trailer. The roof includes a sliding element, preferably movable along the longitudinal axis, to open and close the opening. This allows access to the interior of the trailer, or its cabin, for paramedics, the driver, or similar personnel, enabling them to reach and treat the injured person inside the cabin and to operate or drive the trailer or rescue vehicle, similar to the previously described swiveling driver's cab. Accordingly, the driver's side, including the controls, steering wheel, and other components of the trailer, can be located at or accessible from the point where the opening allows entry for the person or driver.A driver's seat or similar, preferably foldable when not in use, can also be located there. Simultaneously designing the opening to be closable by means of a sliding element can improve protection during movement or use on the battlefield.

[0076] According to a further aspect of the invention, the driver's cab, preferably made of glass, is essentially movably connected to the sliding element, and furthermore, the driver's cab, preferably made of glass, is formed by a fixed windshield on the front of the trailer. This can represent a concrete implementation option that simultaneously ensures a fixed and thus stably arranged windshield of the trailer or its driver's cab.

[0077] The present invention further relates to a trailer for use in a recovery unit as described above, which is designed to be pivotably connected in one direction of travel to a trailer coupling of a recovery unit as described above, wherein the trailer is designed to be connected, preferably wirelessly, to the recovery unit, preferably to its vehicle, and wherein the trailer has a control unit designed to control the recovery unit, preferably its vehicle. This allows a suitable trailer to be provided for implementing a recovery unit as described above and for utilizing its features and advantages.

[0080] Fig. Figure 1 shows a representation of a recovery unit 1, 2 according to the invention as an unmanned vehicle 1 with a recovery attachment 2 according to a first embodiment with the crane 21 fully folded in, with the counterweight 25 retracted and without the recovery container 3 from the front. Fig. 2 shows the representation of the Fig. 1 with crane tilted upwards 21. Fig. Figure 3 shows a recovery attachment 2 according to the invention for the recovery unit 1-3 of the Fig. 1 with crane fully folded in 21 from the front. Fig. Figure 4 shows a detailed view of a swivel drive 23 of the recovery attachment 2. Fig. 5 shows the representation of the Fig. 1 with the recovery container 3 in a transport position from the left side. Fig. Figure 6 shows a representation of the recovery attachment 2 with the raised recovery container 3 according to a first embodiment without an unmanned vehicle 1. Fig. Figure 7 shows a front view of the recovery container 3 according to the invention, based on the first embodiment.

[0081] The vehicle 1, which serves as the basis of the recovery unit 1-4 according to the invention, is, according to the considered embodiments, an all-terrain wheeled vehicle for military operations, which can move remotely controlled or autonomously on a surface 50 of a substrate 5 or ground 5. Such unmanned land vehicles 1 can also be referred to as "unmanned ground freeride vehicles (UGVs)".

[0082] The unmanned vehicle 1 has a frame 10, which can also be referred to as a chassis 10. Three axles (not labeled), each with a pair of wheels 11, are arranged on the frame 10. The unmanned vehicle 1 can travel on these wheels on the surface 50 of the ground 5 in a forward direction A and in the opposite direction, in reverse. The direction of travel A is oriented along the longitudinal axis X in the illustrations.

[0083] The unmanned vehicle 1 has sensors 12 on all four sides, i.e., front, rear, left, and right, such as cameras (including night vision and infrared sensors), laser scanners, and the like, to detect the surroundings in the horizontal X, Y planes in all directions. This enables autonomous orientation and the detection of obstacles and casualties 6 to be rescued. Lights 13 or headlights 13 are also provided, at least at the front, to illuminate the surroundings for optical detection. A ball-type coupling 16 is provided on the rear side opposite the longitudinal axis to allow, for example, the towing of a trailer 9, as shown below. Fig. 19, Fig. 20 to Fig. 21 will be described in more detail.

[0084] The unmanned vehicle 1 has a cuboid-shaped receiving space 14 projecting along the vertical axis Z onto its upper surface, or from above into the frame 10. This receiving space is a recess in the upper surface of the frame 10 of the unmanned vehicle 1. Along the transverse axis Y, the cuboid receiving space 14 is bounded by the three wheels 11 and the frame 10. Along the longitudinal axis X, the cuboid receiving space 14 is bounded at the front and rear by the frame 10. A recovery container 3, see for example [reference], can be placed in this cuboid receiving space 14. Fig. 7, approximately halfway along the vertical axis Z, to be picked up there as a transport position and held with play, see for example Fig. 5, as will be described in more detail below with regard to the recovery attachment 2.

[0085] Furthermore, a deflector 15 is detachably arranged at the front of the unmanned vehicle 1 on the frame 10, which, viewed from the side, has a triangular contour that rises in a straight line from front to back in order to guide or bend branches and the like upwards over the recovery container 3, which is in the transport position, during movement or travel in the direction of travel A.

[0086] The previously mentioned recovery attachment 2 itself has a frame 20, which can also be referred to as a frame 21. The lower part of the frame 20 of the recovery attachment 2, along the vertical axis Z, is designed as a cuboid-shaped bracket 20a, which corresponds to the inner contour of the cuboid-shaped receiving space 14 of the frame 10 of the unmanned vehicle 1 and can thus be positively engaged with the cuboid-shaped receiving space 14 of the frame 10 of the unmanned vehicle 1 and held there. This can be further improved by additional side supports 20b of the frame 20 of the recovery attachment 2, which rest on the lateral edges of the frame 10 of the unmanned vehicle 1 above the wheels 11 and can be held there by means of fastening elements 20c such as screws, clamps, straps, and the like.Furthermore, damping elements 20d in the form of rubber elements 20d or rubber blocks 20d are arranged downwards at the four lower corners of the frame 20 of the recovery attachment 2 to dampen vibrations between the frame 10 of the unmanned vehicle 1 and the frame 20 of the recovery attachment 2. The cuboid bracket 20a of the frame 20 of the recovery attachment 2 has a form-fitting contour not only on the outside towards the cuboid receiving space 14 of the frame 10 of the unmanned vehicle 1, in order to be held there, but also on the inside a suitable contour to receive the recovery container 3 and hold it with some play.

[0087] The aforementioned crane 21 is arranged on one of the lateral edges (not labelled) of the frame 20 of the recovery attachment 2 and is designed to be somewhat shorter along the transverse axis Y, i.e. perpendicular to the longitudinal axis X or perpendicular to the direction of travel A, than corresponds to the width of the vehicle 1 or its frame 10, see for example Fig. 3. The crane 21 has a crossbeam 21a extending along the longitudinal axis X and arranged parallel to the corresponding edge of the frame 20 of the recovery attachment 2, which is rotatably mounted at both ends on the corresponding side support 20b of the frame 20 of the recovery attachment 2 by means of a bearing element 21b, see for example Fig. 6. The lower or inner end of each of the two bearing elements 21b is fixedly connected to the crossbeam 21a, so that it can be pivoted together with the crossbeam 21a about the axis of rotation of the crossbeam 21a or the crane 21. A gear 21c is also arranged inside the end of the front pivot arm 21d, as viewed in the direction of travel A, and rotates with the crossbeam 21a. The function of this gear will be described in more detail below.

[0088] The opposing upper or outer ends of the swivel arms 21d of the crane 21 are connected to each other by a drum bar 21e, which is rotatably mounted at each end of one of the swivel arms 21d by means of a rod bearing 21h. The drum bar 21e of the crane 21 thus runs parallel to the crossbeam 21a of the crane 21, which also applies to its axis of rotation. An electric drum drive 21g is fixedly arranged on the swivel arm 21d that is forward when viewed in the direction of travel A, in order to drive the drum bar 21e in a rotating manner. For this purpose, two cables 22 can be wound and unwound along the vertical axis Z by means of cable drums 21f, which are fixedly arranged on the drum bar 21e at intervals along the longitudinal axis X, in order to raise and lower the recovery container 3 along the vertical axis Z, see for example. Fig. 6.

[0089] The slewing movement B of the crane 21 relative to the frame 20 of the recovery attachment 2 is made possible by a slewing drive 23 being fixedly mounted on the bracket 20a of the frame 20. The slewing drive 23 has a rack 23a extending along the transverse axis Y, which can be moved back and forth along the transverse axis Y by means of a ball screw drive 23b by means of a thrust movement B. The ball screw drive 23b is driven by an electric motor 23c. The rack 23a is engaged by means of its teeth with the aforementioned gear 21c of the front slewing arm 21d, so that the translational movement of the slewing drive 23 along the transverse axis Y can be converted into a rotary movement of the crossbeam 21a, i.e., the slewing movement A of the crane 21, by means of its rack 23a and the gear 21c of the front slewing arm 21d.

[0090] On that side of the recovery unit 1-3 or its recovery attachment 2, there is also a retractable counterweight 25, the weight of which corresponds to the weight of the recovery container 3. The counterweight 25 has a weight element 25a in the form of armor 25a, which can be extended and retracted by means of a thrust drive 25b along the transverse axis Y relative to the frame 20 of the recovery attachment 2 or relative to the frame 10 of the unmanned vehicle 1, see for example Fig. 8. This allows the moment of the recovery unit 2, which can be lowered and lifted along the transverse axis Y on the opposite side of the unmanned vehicle 1, to be balanced as much as possible.

[0091] The previously mentioned recovery container 3 is cuboid in shape and in turn has a frame 30, which is rod-shaped or cage-shaped and forms the edges and corners (not designated) of the recovery container 3.

[0092] A fixed base 31 is arranged on the frame 30 of the recovery container 3, which closes off the recovery container 3 or its interior along the vertical axis Z downwards.

[0093] Along the transverse axis Y, side walls 32 are arranged on both sides of the frame 30 of the recovery container 3. Each of these side walls can be folded laterally and downwards around its lower edge (not labeled), which runs along the longitudinal axis X, to provide access to the interior of the recovery container 3. A damping element 32a in the form of a gas spring 32a is arranged on the outer edges of each side wall 32 to compensate for its weight when the respective side wall 32 is folded open and closed (see figure). Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16 to Fig. 17. Furthermore, each side wall 32 has a window 32b where the head or face of the wounded person 6 is located during transport, so that the wounded person 6 can look out during transport in the rescue container 3, see also Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16 to Fig. 17.

[0094] Similarly, the recovery container 3 has two end faces 33, which are also arranged to be foldable or retractable on the frame 30 of the recovery container 3. The end faces 33 also have damping elements 33a in the form of gas springs 33a for this purpose; see also Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16 to Fig. 17.

[0095] Along the vertical axis Z, a roof 34 forms a fixed upper boundary for the interior of the recovery container 3. The roof 34 also has windows 34a; see also [reference]. Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16 to Fig. 17.

[0096] The recovery container 3 is armored by means of the outward-facing surfaces of its side walls 32, front surfaces 33, floor 31, and roof 34 being designed to at least withstand rifle fire. This can increase the protection of the wounded 6 inside the recovery container 3.

[0097] In order to stand securely on the substrate 5 or its surface 50, the underside (not designated) of the bottom 31 of the recovery container has four rectangularly arranged feet 36 in pairs along the longitudinal axis X and Y, equally spaced from each other along the transverse axis Y, which can also be designed as corresponding skids 36 for pulling the recovery unit 3 along the longitudinal axis X.

[0098] Fig. Figure 8 shows a representation of a recovery unit 1-2 according to the invention as an unmanned vehicle 1 with recovery attachment 2 according to a second embodiment with crane 21 folded up, with counterweight 25 retracted and without recovery container 3 from the front.

[0099] In this case, the slewing drive 23 is partially relieved by a damping element 24, which connects the upper region of the front slewing arm 21d to the frame 20 of the recovery attachment 2 or to the frame 10 of the unmanned vehicle 1, transmitting tensile force. For this purpose, a gas spring 24a of the damping element 24 is arranged along the transverse axis Y and is oriented towards the counterweight 25 or away from the side of the recovery attachment 2 on which the crane 21 or its crossbeam 21a is located. On the side of the recovery attachment 2 or its frame 20 that faces away from the side of the recovery attachment 2 on which the crane 21 or its crossbeam 21a is located, a deflection element 24c in the form of a deflection pulley 24c of the damping element 24 is arranged. A tension element 24b in the form of a rope 24b of the damping element 24 runs between the gas spring 24a and the crane 21 orwhose swivel arm 21d around the deflection pulley 24c, so that the power transmission can be carried out by means of a pulley mechanism and in a comparatively compact manner.

[0100] Fig. Figure 9 shows a representation of the recovery unit 1, 2, 4 according to the invention as an unmanned vehicle 1 with recovery attachment 2 according to the first embodiment when lowering a load carrier 4 with goods 40 into a depression 51 from the left side.

[0101] In this case, instead of the previously described recovery container 2, a load carrier 4 is used to be transported by the unmanned vehicle 1 and set down by means of its crane 21, as shown in the illustration of the Fig. 9 in a trench 51 as an example of a depression 50 in the ground 5. There, the goods 40 can be received as supplies 40 by a person in the form of a soldier 7 or removed from the load carrier 4, which can then be lifted again and swung back into the transport position on top of the unmanned vehicle 1, as previously described. This can also enable the use of the present invention for such applications.

[0102] Fig. Figure 10 shows a perspective view of the recovery unit 1-3 according to the invention as an unmanned vehicle 1 with recovery attachment 2 according to the first embodiment when picking up the recovery container 3 according to the first embodiment with wounded persons 6 in a first step.

[0103] Previously, the recovery unit 1-3 had already autonomously moved to the location where two wounded soldiers were to be recovered. A medic (not shown) was already present. Upon arrival, the unmanned vehicle 1 took up a position between the soldiers to be recovered and the direction from which fire was expected or possible, in order to protect both the soldiers and the medic, particularly by means of the extendable armor 25a of the counterweight 25. The recovery container 2 was then lowered next to the soldiers using the crane 21, while the counterweight 25a was simultaneously extended laterally to counteract the current weight of the recovery container 2 and the resulting moment around the longitudinal axis X.

[0104] Having been lowered onto the base 5, the paramedic folded down the side wall 32 facing away from the vehicle 1 along the transverse axis Y onto the base 5 in order to reach and remove two stretchers 35 located inside the rescue container 3, or to move or pull them laterally on the floor 31 and on the inside of the folded-down side wall 32. The front face 33, which can also be divided into two sections to allow individual use and keep the other part of the front face 33 closed, is shown open only to allow a view into the interior of the rescue container 3. In practice, it would be folded up and closed, as the paramedic only uses the opening of the folded-down side wall 32 to access the interior of the rescue unit 3.

[0105] Thus, the wounded soldiers to be rescued can be treated relatively safely by only one medic while lying or kneeling within the protection of the unmanned vehicle 1 or its retractable armor 35a, and moved onto a stretcher 35 each, in order to then push these stretchers 35 into the interior of the rescue unit 3, cf. Fig. 11.

[0106] Then the paramedic can fold up the lowered side wall 32 and thus close the interior of the rescue unit 3, cf. Fig. 12. The paramedic can then remain on site or leave the scene in a way that is as protected as possible, or by crawling.

[0107] In the next fourth step, according to the representation of Fig. 13 The recovery unit 3 can now be lifted in a straight line along the vertical axis Z by means of the ropes 22 from the drum drive 21g or lifted off the ground 5.

[0108] Once the recovery unit 3 has reached a height above the top of the frame 10 of the vehicle 1 along the vertical axis Z, the drum drive 21g can be stopped and the slewing drive 23 operated instead to pivot the two slewing arms 21d of the crane 21 inwards in the slewing direction B, i.e., above the vehicle 1. The extended counterweight 25, or its retractable armor 25a, can be retracted synchronously during this process to prevent any unwanted moment from being generated in the direction of the counterweight 25 (see figure). Fig. 14.

[0109] Is the crane 21 swung so far that the recovery unit 3 hangs directly above the cuboid receiving space 14 of the frame 10 of the vehicle 1 or the corresponding receiving space (not labeled) of the frame 20 of the recovery attachment 2, cf. Fig. 15, the recovery container 3 can be lowered by means of the ropes 22 from the drum drive 21g into the receiving space 14 of the frame 10 of the vehicle 1, cf. Fig. 16, to assume its transport position. Meanwhile, the extended counterweight 25 or its retractable armor 25a is already fully retracted again, cf. Fig. 15.

[0110] Finally, the crane 21 can be completely folded down by means of the swivel drive 23 to lie flat on the top of the frame 10 of the vehicle 1, cf. Fig. 17. In this state, the unmanned vehicle 1 can automatically move away from the battlefield to a safe area in order to transfer the wounded 6 it has picked up for further medical care, which can then be done by folding down the front surface 33 to reach the handles (not labelled) of the respective stretcher 35 more quickly and directly.

[0111] A corresponding situation shows Fig. 18 in the form of a representation of the rescue unit 1-3 according to the invention as an unmanned vehicle 1 with rescue attachment 2 according to the first embodiment during the transfer of a wounded person 6 to an ambulance. 8. The ambulance 8 in turn has a frame 80 or chassis 80 with wheels 81. The ambulance 8 has a rear wall 82 in the form of a pair of doors 82 at the rear, wherein the doors 82 each have a closable passage opening 82a, which is arranged along the vertical axis Z at a height to allow access to a wounded person 6 or 81.whose stretcher 35 can be removed from the recovery container 3 of the recovery unit 1-3 according to the invention in as straight a line as possible and transferred to the ambulance 8 without a person such as a paramedic 7 having to leave the ambulance 8, which can improve the protection of the paramedic 7 in this step of the recovery of wounded persons 6.

[0112] Fig. Figure 19 shows a pendant 9 according to a first embodiment, partially in section from above. Fig. Figure 20 shows the recovery unit 1-3 according to the invention as an unmanned vehicle 1 with recovery attachment 2 and recovery container 3 according to the first embodiment during the recovery of a wounded person 6 and with attached trailer 9 according to the invention. Fig. 19 while loading with another wounded man 6. Fig. 21 shows the representation of the Fig. 20 with the recovery container 3 and closed trailer 9. The recovery unit 1-3 together with the trailer 9 can be referred to as the recovery combination 1-3, 9.

[0113] The trailer 9 according to the invention has a frame 90 in the form of a frame 90 or a chassis 90 with two axles (not specified), each with a pair of wheels 91. A trailer drawbar 92 is provided extending forward along the longitudinal axis X in the direction of travel A, and has a trailer coupling 93 in the form of a coupling eye 93 at its front end, cf. Fig. 19, in order to be connected to the trailer coupling 16 with the ball coupling 16, see. Fig. 21.

[0114] On the frame 90 of the trailer 9, a box-shaped or cuboid structure (not labelled) is arranged, which encloses an interior space (not labelled) along the vertical axis Z downwards with a floor (not shown), along the longitudinal axis X forwards with a front 94 or front side 94 with windows 94a, and to the rear with a rear wall 96 or back 96 with closable passage openings 96a, along the transverse axis Y on both sides with side walls 95 with windows 95a, and at the top with a roof 98. The passage openings 96a of the rear 96 are arranged at a height along the vertical axis Z, so that a wounded person 6 on a stretcher 35 can be pushed from the outside through one of the passage openings 96a of the rear 96 into the interior space of the trailer 9, cf. Fig. 20.

[0115] The trailer 9 is unpowered but features a control unit 97 with a steering wheel (not shown) and other operating functions, enabling a person 7, acting as operator 7 or driver 7, to operate and steer the unmanned vehicle 1 of the recovery unit 1-3, thus allowing the trailer 9 to be towed by the unmanned vehicle 1. For this purpose, the trailer 9 and the unmanned vehicle 1 can be connected via a wireless connection D. The window 94a on the front 94 and the windows 95a on each side 95 of the trailer 9 are positioned to provide the driver 7 with a sufficient view of the surroundings to safely operate the recovery unit 1-3, 9.The trailer 9 is armored in that its outward-facing surfaces – the front 94, the side walls 95, the rear wall 96, the floor, and the roof 98 – are designed to at least withstand rifle fire. This can increase the protection of the wounded 6 and the driver 7 in the trailer 9.

[0116] Fig. Figure 22 shows a representation of the recovery unit 1-3 according to the invention as an unmanned vehicle 1 with recovery attachment 2 according to the first embodiment with crane 21 folded up, with counterweight 25 extended and with recovery container 3 according to a second embodiment during the recovery of wounded persons 6 from the front. Fig. 23 shows the representation of the Fig. 22 after the admission of wounded 6. Fig. Figure 24 shows a perspective view of the recovery container 2 according to the second embodiment during the intake of wounded 6. Fig. 25 shows the representation of the Fig. 24 after the admission of wounded 6.

[0117] In this case, the recovery container 3 is designed in two parts, with the bottom 31 being formed by a trough element 37, which has at each of its four corners a centering element 37a projecting upwards along the vertical axis Z in the form of an inclined projection 37a or in the form of an inclined bar 37a, which is inclined inwards and away from the edge of the bottom 31 along both the longitudinal axis X and the transverse axis Y relative to the vertical axis Z. On the upper surface of the bottom 31, pairs of support guides 31a are arranged along the longitudinal axis X, cf. Fig. 24, to receive the feet (not shown) of a stretcher 35 and to guide them movably along the longitudinal axis X.

[0118] The recovery container 3 according to its second embodiment further comprises a lid element 38, which includes the side walls 32, the end faces 33, and the roof 34 with its cable fastenings 34b. In this case, the end faces 33 also have windows 33b, cf. Fig. 24 and Fig. 25. The cover element 38 and the tub element 37 can be joined together and then permanently connected. If this connection is broken, which can be done non-destructively, for example by clamps, latches, and the like, the tub element 37 can remain on the base 5 if the cover element 38 is lifted off and thereby separated from the tub element 37, cf. Fig. 22 and Fig. 23.

[0119] The two-part rescue container 3 can thus be used in such a way that the tub element 37 and the lid element 38 are connected to each other and transported to the location for the rescue of the wounded 6 as described above, where they are initially placed together on the ground 5. The medic (not shown) can then disconnect the tub element 37 from the lid element 38 on site. The lid element 38 is then raised again as described above using the ropes 22, and the tub element 37 remains on the ground 5. Since the top of the base 31 of the tub element 37, where, as described above, two stretchers 35 for receiving the wounded 6 are located, is now freely accessible, apart from the angled bars 37a in the four corners, the medic can move the wounded 6 freely onto the stretchers 35, just as with the rescue container 3 according to the first embodiment.

[0120] The cover element 38 can then be lowered onto the tub element 37 using the ropes 22. The angled rods 37a in the four corners can be helpful in centering the cover element 38 relative to the tub element 37 during lowering. A light source (not shown) can also be located inside the cover element 38, pointing downwards, to illuminate the tub element 37 and the surrounding surface 5. This can be combined with a camera (not shown), also positioned inside the cover element 38, pointing downwards, to provide a person operating the vehicle 1 remotely with a view of the tub element 37 and the surrounding surface 5 while operating the rope drum 21f to lower the rope 22 or the cover element 38.

[0121] Once the lid element 38 has been lowered back onto the tub element 37 or positioned there, the paramedic can re-establish the connection between the tub element 37 and the lid element 38, so that the recovery container 3 can be lifted as a whole and placed in the transport position on the unmanned vehicle 1 as described above.

[0122] Fig. Figure 26 shows a side view of the trailer 9 according to a second embodiment. Fig. 27 shows the representation of the Fig. 26 during the reception of wounded 6 in the lowered state of the trailer 9.

[0123] According to its second embodiment, the trailer 9 has a lifting / lowering device 90a, which is designed to lower and raise that part of the trailer 9 which is designed to accommodate the wounded person 6 and can also be referred to as the cabin, relative to a frame 90 with chassis 91 of the trailer 9 along the vertical axis Z as a vertical lifting movement E. The area around the driver 7, including the floor, side walls 95, front 94, rear 96 and roof 98, can be considered part of the cabin for this purpose.

[0124] The lifting / lowering device 90a has four hydraulic lifting cylinders 90a arranged at the corners of the cabin, which are arranged in pairs opposite each other along the longitudinal axis X and along the transverse axis Y, i.e., located in the four corners of the cabin or frame 90. All four hydraulic lifting cylinders 90a are arranged along the vertical axis Z between the frame 90 of the trailer 9 and its cabin, in order to lower or raise the cabin along the vertical axis Z relative to the frame 90 by means of a lifting movement R.

[0125] This allows the cabin to be lowered onto the ground 5 or its surface 50, enabling the wounded 6 to be moved directly or on stretchers 35 into the trailer 9 or its cabin as level as possible. This allows the wounded 6 to reach the cabin or its interior independently, i.e., if no paramedic is present, and makes it easier for the paramedic to move the wounded 6 inside. It also improves the protection of both the wounded 6 and the paramedic by allowing them to remain as close as possible to the ground 5 during rescue and being rescued.

[0126] Furthermore, the trailer 9 according to the second embodiment is comparatively flat compared to the trailer 9 of the first embodiment, cf. Fig. 20 and Fig. 21, designed, which can also improve protection. This also allows the weight of the trailer 9 and its cabin to be kept low. According to the second embodiment, the only significant raised feature of the trailer 9 is a glass driver's cab 98a made of bulletproof glass, which projects upwards above the roof 98 along the vertical axis Z to allow the driver 7 a view in the horizontal directions X, Y around the trailer 9 and upwards along the vertical axis Z, cf. Fig. 27 and Fig. 28. To allow the driver 7 to enter the interior of the trailer 9, the driver's cab 98 can be folded down to the side, thereby releasing an entry opening (not shown) in which the driver 7 can also sit on a fold-down driver's seat (not shown) to operate the trailer 9 or to drive the recovery vehicle 1-4, 9.

[0127] The trailer 9 according to the second embodiment has two equally sized, closable passage openings 96a arranged along the transverse axis Y on its rear side 96 or rear wall 96. These openings are designed so that a stretcher 35, along with a wounded person 6, can be pushed through the open passage opening 96a of the trailer 9 into its interior and pulled out of its interior. This facilitates the loading and unloading of wounded persons 6 onto stretchers 35 and simultaneously increases protection, as the rear side 96 does not need to be opened further. This improves the handling of wounded persons 6 in both the raised and lowered positions. The removal of wounded persons 6 can typically be carried out in the raised position, which may correspond approximately to the hip height of the medics 7; cf. the loading of wounded persons 6 onto stretchers 35 of the Fig. 20.

[0128] The trailer 9 according to the second embodiment further comprises an extension / retraction mechanism 99, which is designed to be extended along the longitudinal axis X in the opposite direction of travel A from that part of the trailer 9 which is designed to accommodate the wounded person 6, i.e., from the cabin, in order to receive the wounded person 6 directly or on a stretcher 35. The extension / retraction mechanism 99 passes through the open passage opening 96a in the rear wall 96. Thus, the movement of wounded persons 6 into and out of the cabin, even while lying on a stretcher 35, can be facilitated and accelerated by allowing a self-propelled sliding mechanism, similar to a drawer, to be moved back and forth by the wounded person 6, the driver 7, or the paramedic, and thereby extended and retracted to be reached by the wounded person 6 or to transfer the wounded person 6 onto the extension / retraction mechanism 99.whose lying surface (not shown) is placed on top. The extension / retraction mechanism 99 can, however, also be driven by a motor (not shown) to relieve the wounded person 6, the driver 7 or the paramedic from carrying out this task.

[0129] Fig. Figure 28 shows a side view of the trailer 9 according to a third embodiment. Fig. 29 shows the representation of the Fig. 28 with closed opening 98c of the roof 98 of the trailer 9.

[0130] In this case, the roof 98 of the trailer 9 has an opening 98c in the front area of ​​the cabin along the longitudinal axis X or in the direction of travel A, which is designed so that a person such as the driver 7 can reach the interior of the trailer 9 through the opening 98c, i.e., enter the cabin. Thus, the driver 7 can take up or reach his position in order to operate or drive the recovery vehicle 1-4, 9.

[0131] The roof 98 features a sliding element 98b, which is movable or slidable along the longitudinal axis X to open and close the opening 98c. Accordingly, the roof 98 can be closed to protect the interior once the driver 7 is seated inside.

[0132] In this case, too, the previously described glass driver's cab 98a is present. The glass driver's cab 98a is essentially movably connected to the sliding element 98b and is otherwise formed by a fixed windscreen 94b on the front 94 of the trailer, so that a fixed and therefore stable windscreen 94b can be achieved.
