Aid system, in particular for use in ice rescue

Abstract

An aid system includes a base element, an expandable tube arrangement including at least one tube portion to form a tube run extending between a base portion assigned to the base element and a head portion at a free end of the tube run, and a pressurized fluid system that fills the tube portion with pressurized fluid, wherein (i) the tube portion is guided between a tube store and the head portion by a tube guiding device with a tube guiding opening constricting a cross section of the tube portion, and (ii) at least one pressurized fluid inlet leading into the interior of the tube portion in the region of the head portion.

         2 . The aid system according to  claim 1 , wherein the tube arrangement comprises at least two tube portions arranged at a mutual distance from one another. 
     
     
         3 . The aid system according to  claim 1 , wherein the tube guiding device comprises a pair of oppositely rotatable rollers delimiting a gap serving as a tube guiding opening for the tube portion to be guided through, the rollers having parallel axes of rotation and being mounted on the base element. 
     
     
         4 . The aid system according to  claim 3 , further comprising a setting device that changes an axial distance between the rollers. 
     
     
         5 . The aid system according to  claim 1 , comprising a tube storing roller provided on a tube entry side of the tube guiding device that takes up the tube store. 
     
     
         6 . The aid system according to  claim 5 , wherein the tube arrangement comprises two tube portions arranged at a mutual distance from one another and a dedicated tube storing roller is provided for each of the tube portions, wherein the tube storing rollers are fitted in a substantially coaxially rotatable manner on the base part such that an intermediate space is formed between the tube storing rollers. 
     
     
         7 . The aid system according to  claim 1 , wherein the pressurized fluid system has at least one flexible pressurized fluid line leading from the base part to the pressurized fluid inlet on the head portion. 
     
     
         8 . The aid system according to  claim 1 , wherein the pressurized fluid system is a compressed gas system. 
     
     
         9 . The aid system according to  claim 8 , further comprising a mount provided on the base part that receives at least one exchangeable compressed gas containing. 
     
     
         10 . The aid system according to  claim 1 , further comprising a carriage that is moveable along the tube run. 
     
     
         11 . Aid system according to  claim 10 , wherein the tube arrangement comprises two tube portions arranged at a mutual distance from one another and the carriage comprises guiding devices that guide the movement on the tube portions. 
     
     
         12 . The aid system according to  claim 11 , wherein the guiding devices comprise wheels having a cross-sectionally concave running surface, the shape of which is adapted to a shape of an upper side of expanded tube portions such that the wheels roll on the expanded tube portions while being secured against sliding off sideways. 
     
     
         13 . The aid system according to  claim 1 , further comprising at least one deflecting roller fastened to the head portion. 
     
     
         14 . The aid system according to  claim 13 , further comprising an elongated, flexible pulling element, which is led from the base element to the deflecting roller and back in a direction of the base element such that an object fastened to the pulling element can be moved between the base element and the head portion by pulling on a portion of the pulling element. 
     
     
         15 . The aid system according to  claim 1 , further comprising at least one gripping element provided on the head portions. 
     
     
         16 . The aid system according to  claim 2 , wherein the tube arrangement has a flexible sheet-like element extending between the tube portions. 
     
     
         17 . The aid system according to  claim 16 , wherein the sheet-like element is detachably fastened to the tube portions. 
     
     
         18 . The aid system according to  claim 16 , wherein the sheet-like element is an elongated web-like element separate from the tube portions and has on its longitudinal sides loops for the tube portions to be led through. 
     
     
         19 . The aid system according to  claim 16 , wherein the sheet-like element is produced from water-impermeable, tension-resistant flat material. 
     
     
         20 . The aid system according to  claim 1 , which is configured for use in ice rescue.
