Fastening component, in particular a spacer element

Abstract

A fastening component, a spacer element in particular, for structural components such as heat shields ( 25, 37 ) with a strip-like enclosing element ( 1 ) for application in certain sections on a heating element ( 3 ) to be shielded, has on the enclosing component ( 1 ) spring-loaded connecting components ( 21 ) by means of which the enclosing element ( 1 ) may be fastened on the heating element ( 3 ) so as to be stationary.

1 . A fastening component, in particular a spacer element, for structural components such as heat shields ( 25 ,  37 ) having a strip-like enclosing component ( 1 ) for application in certain sections to a heating element ( 3 ) to be shielded and having spring-loaded connecting points ( 21 ) provided by means of which the enclosing component ( 1 ) may be fastened on the heating element ( 3 ) so as to be stationary. 
   
   
       2 . The fastening component according to  claim 1 , characterized in that the enclosing component is in the form of a band clamp ( 1 ) the length of which is dimensioned so that it surrounds the outer circumference of the heating element ( 3 ) in part, by preference to approximately one-half the enclosing length. 
   
   
       3 . The fastening component according to  claim 2 , wherein the connecting components are in the form of flat tensioning springs ( 21 ) which extend away from the band clamp ( 1 ) as extensions of such band clamp. 
   
   
       4 . The fastening component according to  claim 3 , wherein the tensioning springs are in a form ( 21 ) such that they are applied under spring tension to the heating element ( 3 ) by way of a tensioning area ( 23 ) on the heating element ( 3 ) enclosed and wherein they are bent outward area away from the heating element ( 3 ) between the tensioning area ( 23 ) and their free end ( 33 ). 
   
   
       5 . The fastening component according to  claim 4 , wherein the band clamp ( 1 ) is shaped in partial length areas so as to follow the course of the outer circumference of the heating element ( 3 ) and in other partial length areas is provided with bending sections ( 9 ,  11 ,  17 ) for extension at a distance from the heating element ( 3 ). 
   
   
       6 . The fastening component according to  claim 5 , wherein the band clamp ( 1 ) has on both ends ( 5 ) an end bending section ( 17 ) spaced on each end thereof a distance from the heating element ( 3 ). 
   
   
       7 . The fastening component according to  claim 6 , wherein the tensioning springs ( 21 ) extend from an area ( 19 ) spaced at a distance from the heating element ( 3 ) of the end bending sections ( 17 ) to the tensioning area ( 23 ) diagonally to the outer surface of the heating element ( 3 ) enclosed. 
   
   
       8 . The fastening component according to  claim 2 , wherein the band clamp ( 1 ) has on both ends ( 5 ) an extension ( 7 ) extending from the outer circumference of the enclosed heating element ( 3 ) to the extension bent outward which forms fastening points for built-on components such as heat shields ( 25 ). 
   
   
       9 . The fastening component according to  claim 8 , wherein the fastening points on the extensions ( 7 ) are provided, for formation of a threaded joint, with a heat shield ( 25 ) having at least one screw hole, preferably with a forced-in nut ( 29 ) mounted thereon. 
   
   
       10 . The fastening component according to  claim 9 , wherein there is provided on the band clamp ( 1 ), in the area of bending sections ( 9 ,  11 ) between its ends ( 5 ), a bolting element ( 15 ) spaced a distance from the enclosed heating element ( 3 ) for fastening of a second heat shield ( 37 ). 
   
   
       11 . The fastening component according to  claim 10 , wherein each of the first and second heat shields ( 25 ,  37 ) forms at least in part an encapsulation of approximately one-half the enclosing areas of the heating element ( 3 ) diametrically opposite each other. 
   
   
       12 . The fastening component according to  claim 2 , wherein the strip-like band clamp ( 1 ) is formed to be integral with the spring-loaded connecting springs ( 21 ), by preference a band clamp of a stainless steel possessing elastic properties.
