Hose made from an elastic material

Abstract

Hose made from an elastic material, which is designed to be fitted on a hose connection by means of a hose endpiece of the hose being pushed over the hose connection, and which is designed to be fastened on the hose connection by a hose clip to be arranged in a fitting region of the hose endpiece, wherein the hose endpiece has at least one thickened area which protrudes from the outer side of the hose, said thickeded area protruding from the outer side of the hose at least to such an extent that a hose clip suitable for fastening the hose on the hose connection is held on the hose endpiece by the thickened area, with respect to the influence of gravity when this is effective in the longitudinal direction of the hose endpiece. The invention further relates to a hose having at least two branch-off points.

1 . A hose made from an elastic material for assembly on a hose connector by pushing a hose end piece of the hose over the hose connector and for fastening on the hose connector by a hose clip to be arranged in an assembly region of the hose end piece, wherein the hose end piece comprises at least one thickened portion protruding from the outside of the hose, which protrudes from the outside of the hose at least so far that a hose clip that is suitable for fastening the hose on the hose connector is held on the hose end piece by the thickened portion against the influence of gravity, when the latter is effective in the longitudinal direction of the hose end piece. 
     
     
         2 . The hose as claimed in  claim 1 , wherein the thickened portion runs completely about the outer circumference of the hose. 
     
     
         3 . The hose as claimed in  claim 1 , wherein the thickened portion is arranged in the assembly region for the hose clip. 
     
     
         4 . The hose as claimed in  claim 1 , wherein at least two thickened portions are provided, which each run about the outer circumference of the hose and each have the same spacing from the face end of the hose end piece. 
     
     
         5 . The hose as claimed in  claim 1 , wherein the thickened portion, viewed from the face end of the hose end piece, is arranged in front of the assembly region for the hose clip. 
     
     
         6 . The hose as claimed in  claim 1 , wherein the thickened portion, viewed from the face end of the hose end piece, is arranged behind the assembly region for the hose clip. 
     
     
         7 . The hose as claimed in  claim 1 , wherein at least one first thickened portion, viewed from the face end of the hose end piece, is arranged in front of the assembly region for the hose clip, and at least one second thickened portion, viewed from the face end of the hose end piece, is arranged behind the assembly region for the hose clip, wherein the spacing between the first and the second thickened portion is equal in size or slightly larger than the width of the hose clip. 
     
     
         8 . The hose as claimed in  claim 3 , wherein the dimension by which the thickened portion protrudes from the outside of the hose decreases in the direction of the face end of the hose end piece. 
     
     
         9 . The hose as claimed in  claim 3 , wherein the sum of the outer diameter of the hose end piece and the dimension by which the thickened portion protrudes from the outside of the hose is greater than the inner diameter of the hose clip in the loose state. 
     
     
         10 . The hose as claimed in  claim 3 , wherein the thickened portion completely runs about the outer circumference of the hose, has a circular outer contour viewing the face end of the hose end piece from the top and has a diameter which is larger than the inner diameter of the hose clip in the loose state. 
     
     
         11 . The hose as claimed in  claim 3 , wherein the dimension by which the thickened portion protrudes from the outside of the hose is in the range from 1 to 4 mm. 
     
     
         12 . The hose as claimed in  claim 1 , wherein the hose comprises at least two branch-off points on each of which a hose section having in each case a hose end piece is arranged. 
     
     
         13 . A hose made from an elastic material, wherein the hose comprises at least two branch-off points, on each of which a hose section having in each case a hose end piece is arranged, which is formed for assembly on a hose connector by pushing the hose end piece over the hose connector and for fastening on the hose connector by a hose clip to be arranged in the region of the hose end piece. 
     
     
         14 . The use of a hose as claimed in  claim 13 , for transporting a coolant for cooling batteries, in particular for electric or hybrid vehicles. 
     
     
         15 . A battery arrangement for electric or hybrid vehicles with a plurality of individual battery elements, each of which comprises a coolant supply connection and a coolant discharge connection, wherein the coolant supply connections are interconnected and connected to a coolant source via a hose as claimed in any one of the preceding claims and/or the coolant discharge connections are interconnected and connected to a coolant sink via a hose.
