Definitions

  • the invention relates to the use of a rescue operation load distribution element for supporting pressure-generating rescue equipment on an accident vehicle according to the claims.
  • dimensionally stable pressure plates and sill attachments are used to support and distribute the load of rescue equipment, in particular hydraulic rescue cylinders, mechanical gear winches, spreading tools and the like, on external objects such as vehicle components, in particular dashboards, sills and door sections. Due to their rigid shape, these pressure plates and sill attachments cannot be used universally on every surface or in every operational situation, which hinders efficient and rapid operation or even impairs the functionality of the rescue equipment. For example, dimensionally stable pressure plates for support on fittings are not suitable for support on all types of sills and vice versa. In addition, emergency organizations usually carry a number of pressure plates and sill attachments of different contours and sizes in order to be able to meet the specific operational requirements.
  • pressure plates and sill attachments according to the state of the art have a high mass in order to withstand the loads and can therefore only be transported over short distances and with difficulty. Due to their bulkiness and the large number of different designs and sizes required, valuable storage space in rescue vehicles is taken up and an efficient response is hindered. Overall, this also results in a longer period of danger for all those involved in the operation.
  • Load distribution elements are DE 20 2007 016946 U1 , EN 10 2009 051255 A1 and the DE 13 22 445 U known.
  • the object of the present invention was to overcome the disadvantages of the prior art and to provide a device by means of which a user is able to achieve a simple, fast and stable load distribution between a pressure-generating rescue device and an external object, in particular an accident-damaged vehicle. This should enable rescue operations, in particular to rescue accident-damaged or injured persons, to be carried out more quickly and safely for all those involved.
  • the rescue operation load distribution element for supporting pressure-generating rescue devices, in particular hydraulic rescue cylinders, mechanical gear winches, spreading tools and the like, on an accident-damaged vehicle.
  • the rescue operation load distribution element comprises at least one load-bearing surface for introducing a support load of a rescue device and at least one load transfer surface for transferring the support load to an external object.
  • At least the load transfer surface is formed by a shape-changing boundary casing.
  • the boundary casing delimits at least one chamber, at least in sections, the chamber being at least partially filled with a flowable or overall shape-flexible filling material.
  • a rescue load distribution element has the advantage that, due to its shape flexibility, it can be used universally on different vehicle components or in many application situations and is suitable, for example, for support on dashboards as well as on sills and door sections. Furthermore, the rescue load distribution element can also be positioned under a vehicle or used for support on soft surfaces, such as wet floors. Support on trees or similar is also conceivable. This makes it possible to meet the specific application requirements better or more quickly with just one or just a few rescue load distribution elements and also to save valuable storage space in emergency vehicles. In addition, the rescue load distribution element is particularly uncomplicated to use and can therefore be used quickly.
  • Handling elements serve both to facilitate manual transport and simple positioning, while fixing elements can act as fixing or attachment points for slings, ropes, chains and the like.
  • fixing elements can act as fixing or attachment points for slings, ropes, chains and the like.
  • the handling and/or fixing elements serve, for example, to create a load triangle.
  • the handling and/or practicality of use, in particular with regard to avoiding undesirable slipping tendencies of the rescue load distribution element, can thus be further improved.
  • the at least one handling and/or fixing element can be designed as a handle, flexible loop or eyelet.
  • Handles facilitate manual transport and/or positioning in particular.
  • Flexible loops or eyelets can primarily serve as fixing or attachment points for slings, ropes, chains or the like in order to be able to safely maintain the desired position during the respective rescue operation.
  • the boundary cover may also be expedient for the boundary cover to be designed to be liquid-repellent or liquid-tight or to have a liquid-repellent or liquid-tight impregnation.
  • the rescue load distribution element can be used without any problems even during rainfall or in water without suffering any significant impairment of its functionality.
  • the rescue load distribution element can be exposed to various vehicle fluids, such as oils or fuels, without causing a significant increase in the risk of fire.
  • this design can prevent the mass of the rescue load distribution element from increasing in a disadvantageous way or its usability from changing in any other way.
  • the boundary cover has at least in sections a slip-resistant surface which is formed by a coating or at least partially consists of an anti-slip material, for example an elastomeric plastic.
  • a slip-resistant surface which is formed by a coating or at least partially consists of an anti-slip material, for example an elastomeric plastic.
  • the boundary cover can be made of non-flammable or flame-retardant material or have a non-flammable or flame-retardant coating. This can reduce the risk of fire or burns to those involved in the operation when it comes into contact with flammable substances and/or when exposed to heat. This design increases safety for all those involved in the operation and can also extend the service life of the rescue load distribution element.
  • the limiting cover is made of a flexible material with increased tear resistance, for example aramid, leather, natural fibers, carbon fibers or a combination thereof, so that the rescue load distribution element can withstand a load of more than 20 kN.
  • This is of increased importance for the rescue load distribution element to have the highest possible transverse pressure dimensional stability, which means that a wide range of applications can be covered.
  • the high level of robustness also benefits the highest possible functional reliability and service life.
  • the filling material can be made of a granular substance, for example sand, plastic, or a mixture of these components.
  • a granular filling material By using a granular filling material, the highest possible transverse pressure dimensional stability of the rescue load distribution element can be achieved.
  • granular filling materials can adapt particularly well to a wide variety of surface profiles or to strongly varying contours and thus implement the load distribution as evenly as possible. In addition, this can increase safety against abrupt, undesirable slipping movements.
  • the filling material can be made from a loose knit or structure made from fibers, for example cotton wool.
  • This design offers a great weight advantage, so that the rescue load distribution element can be transported quickly and easily even over long distances. This can reduce the duration of the operation and the risk for everyone involved.
  • the filling material is made of a liquid, particularly water, or a gel-like substance, since liquids or gels are easily moldable.
  • water in particular is usually an easily available resource during rescue operations, which facilitates simple and rapid variability of the filling level of the rescue load distribution element.
  • the chamber is divided into several at least partially separated sub-chambers, so that a minimum degree of distribution of the filling material is ensured.
  • This can ensure that the filling material is distributed sufficiently evenly between the load-bearing surface and the load-transfer surface, thus positively influencing the load distribution function.
  • this can easily prevent the filling material from accumulating on one side in relation to the boundary shell.
  • these sub-chambers achieve a minimum degree of distribution of the filling material, whereby the filling material cannot be displaced in such a way that direct contact occurs between the load-bearing surface and the load-transfer surface.
  • this measure increases the transverse pressure dimensional stability of the rescue load distribution element and improves safety in use.
  • a completely closed chamber is formed by means of the limiting casing. This ensures uncomplicated handling of the rescue load distribution element, since undesirable leakage of the filling material can be prevented.
  • the proportion of filling material in the maximum volume of the chamber may be more than 33%, in particular more than 50%, preferably in a range of at least 60% up to and including 98%.
  • a sufficiently high or balanced proportion of filling material ensures that there is no direct Contact between the load-bearing surface and the load-transfer surface would occur, which would negatively affect the transverse pressure dimensional stability of the rescue load distribution element.
  • this can ensure that the rescue load distribution element is sufficiently flexible in terms of shape.
  • this can achieve the most comprehensive possible form fit between the load-transfer surface and the external object, in particular with respect to a vehicle contour, so that the risk of the rescue load distribution element slipping can be minimized.
  • the limiting casing is designed to be airtight or has an airtight impregnation and has a valve, preferably a vacuum valve, with which a flow connection between the limiting casing, in particular the external environment of the rescue load distribution element, and the chamber can be established and prevented as required.
  • the vacuum valve can be used to at least partially evacuate the at least one chamber in the rescue load distribution element.
  • valves are attached to the side of the rescue load distribution element, in particular in the casing section of the limiting casing that connects the load-bearing surface and the load-distribution surface. This can prevent damage caused by support and/or load application, which can have a positive effect on the product lifespan.
  • the boundary cover prefferably be made of airtight material or for the boundary cover to have an airtight impregnation or for the boundary cover to comprise an inner cover made of airtight material or for the boundary cover to comprise an inner cover, which inner cover has an airtight impregnation, wherein the inner cover is located between the boundary cover and the chamber.
  • Airtight material can be realized, for example, by using thermoplastic polyurethane.
  • the boundary shell and/or the inner shell has a closable opening through which the amount and/or type of filling material can be changed or replaced.
  • the rescue load distribution element to be adapted to specific operating conditions and the product lifespan to be increased.
  • the filling material is water
  • the fill level of the boundary shell can be quickly and easily adapted to the respective operating conditions using the closable opening. This is particularly true with regard to reducing the fill level starting from a comparatively high fill level. This feature also makes cleaning easier, particularly in the event of soiling during use.
  • such openings are installed on the side of the rescue load distribution element, particularly in the section of the boundary casing that connects the load-bearing surface and the load-distribution surface. This can prevent damage caused by support and/or load application, which can have a positive effect on the product's service life.
  • the chamber contains at least one comparatively dimensionally stable pressure element with a predefined support contour in addition to the flowable and/or dimensionally flexible filling material.
  • This pressure element can serve to stabilize the rescue load distribution element by predefining and/or supporting the load-bearing surface and/or the load-distribution surface. In an advantageous manner, this can also achieve partial stiffening or a predefined shape or dimensional stability of a desired shape.
  • a comparatively dimensionally stable pressure element increases the transverse pressure dimensional stability of the rescue load distribution element.
  • a comparatively dimensionally stable pressure element with a predefined outline or support contour is attached to the outside of the limiting casing, whereby the outline or support contour has the load-bearing surface. Due to its dimensionally stability, this outline or support contour is particularly advantageous for supporting a rescue cylinder on the load-bearing surface of the rescue operation load distribution element, while the support on the load-bearing side is provided by the dimensionally flexible limiting casing.
  • This embodiment combines The technical advantages of flexible and dimensionally stable support and load distribution structures can be used in a practical manner.
  • the risk of damage to the limiting shell can be kept to a minimum even if a rescue device supported on the rescue load distribution element has a relatively small support surface, as is typically the case with a hydraulic rescue cylinder.
  • a rescue device supported on the rescue load distribution element has a relatively small support surface, as is typically the case with a hydraulic rescue cylinder.
  • point loads on the load-bearing surface can be avoided.
  • undesirable sliding movements of the pressure-generating rescue device can be prevented by means of a support contour that is, for example, step-like, rung-like or wave-like.
  • the relatively dimensionally stable pressure element is made of hard rubber or plastic.
  • the shape of the relatively dimensionally stable pressure element can preferably be adapted to the shape and size of the rescue cylinder or can be larger in shape and size than the rescue cylinder. This makes it easier to apply force from the rescue cylinder to the rescue load distribution element over a large area.
  • the comparatively dimensionally stable pressure element may be connected in a fixed position to the limiting shell and/or the inner shell, so that, in particular during the positioning of the rescue load distribution element and rescue device, there are no undesirable displacements of the pressure element relative to the limiting shell and/or inner shell.
  • a coupling means that can be operated manually and/or without tools to be designed for the detachable connection of the comparatively dimensionally stable pressure element to the limiting cover and/or the inner cover as required.
  • the detachable connection can be implemented using straps, lashing straps, Velcro fasteners and/or magnets, for example.
  • the limiting cover has a coupling means that can be activated and deactivated manually, in particular a Velcro fastener, at least in sections, and that several rescue load distribution elements can be connected or stacked as required using the coupling means.
  • rescue load distribution elements can be stacked in an advantageous manner, for example, and thus on the one hand act as raised support points and on the other hand serve to create a triangle of forces.
