Insulating means and combination of a screed and an insulating means

Abstract

Insulating means to be used with a screed for a road finishing machine comprises at least one insulating element and one connection element for a releasable connection with the screed. The insulating element is designed to cause, in a state of the insulating means connected with the screed, a reduced emission of heat from the screed through the insulating element.

What is claimed is: 
     
         1 . Insulating means to be used with a screed for a road finishing machine, the insulating means comprising an insulating element and a connection element for a releasable connection with the screed, wherein the insulating element is designed to cause, in a state of the insulating means connected with the screed, a reduced emission of heat from the screed through the insulating element. 
     
     
         2 . The insulating means according to  claim 1 , wherein the insulating element comprises an insulating material on a surface facing the screed or facing away from the screed in a state of the insulating means connected with the screed. 
     
     
         3 . The insulating means according to  claim 2 , wherein the insulating material comprises one of rubber, polyurethane, composite foam. 
     
     
         4 . The insulating means according to  claim 1 , wherein the insulating means comprises an active heating element for heating the screed in a state of the insulating means connected with the screed. 
     
     
         5 . The insulating means according to  claim 4 , wherein the active heating element is integrated in the insulating element or is arranged on a side of the insulating element facing the screed in a state of the insulating means connected with the screed. 
     
     
         6 . The insulating means according to  claim 4 , wherein the active heating element comprises an electric heating element, and the insulating means comprises an accumulator which is or can be connected with the active heating element for supplying current to the active heating element. 
     
     
         7 . The insulating means according to  claim 1 , wherein the insulating element can reduce emission of heat from the screed through the insulating element by at least 25%. 
     
     
         8 . The insulating means according to  claim 1 , wherein the insulating element is configured to reduce emission of heat from the screed through the insulating element by at least 50%. 
     
     
         9 . The insulating means according to  claim 1 , wherein the insulating element is configured to reduce emission of heat from the screed through the insulating element by at least 75%. 
     
     
         10 . The insulating means according to  claim 1 , wherein the connection element is designed as part of a security system for enabling a heating process of the screed only in a connected state of the screed with the insulating means. 
     
     
         11 . The insulating means according to  claim 1 , wherein the insulating means comprises at least two of the insulating elements. 
     
     
         12 . The insulating means according to  claim 11 , wherein each insulating element weighs less than 20 kg. 
     
     
         13 . The insulating means according to  claim 12 , wherein each insulating element weighs less than 10 kg. 
     
     
         14 . A combination of a screed and the insulating means according to  claim 1 , wherein the insulating element is arranged at least at a portion of a surface of the screed, and wherein the screed comprises a heating means for heating the screed. 
     
     
         15 . The combination according to  claim 14 , wherein the screed comprises a security system which only enables an activation of the heating means if the connection element of the insulating means is connected with the security system of the screed. 
     
     
         16 . The combination according to  claim 14 , wherein the insulating means comprises at least two of the insulating elements, and the insulating elements together cover at least 50% of the surface of the screed.
