Helmet holder for a vision device, in particular for a night vision device

Abstract

A holder for fixing at least one vision device, in particular a night vision device ( 2 ) on a head covering, such as a helmet ( 5 ), of a user ( 1 ), comprises a support element ( 7 ) which can be fixed indirectly or directly to the helmet ( 5 ), an arm ( 8 ) coordinated with the support element ( 7 ), a receptacle ( 9 ) for the vision device being arranged so as to be pivotable about the arm ( 8 ), with the result that a pivot movement of the vision device between an operating position and a rest position is permitted. A rotating element non-rotatably connected to the receptacle ( 9 ) is coordinated with the arm ( 8 ), a spring being arranged on the rotating element in a manner such that the receptacle ( 9 ) is under spring force both in the operating position and in the rest position. Furthermore, a stop element ( 13 ) is provided, by means of which the position of the vision device in the operating position can be set and fixed in a defined manner.

1 . A holder for fixing at least one vision device, in particular a night vision device ( 2 ), on a head covering, such as a helmet ( 5 ), of a user ( 1 ), comprising 
 a support element ( 7 ) which can be fixed indirectly or directly to the helmet ( 5 )    an arm ( 8 ) coordinated with the support element ( 7 ), a receptacle ( 9 ) for the vision device being arranged so as to be pivotable about the arm ( 8 ), thus permitting a pivot movement of the vision device between an operating position and a rest position, wherein a rotating element ( 20 ) non-rotatably connected to the receptacle ( 9 ) is coordinated with the arm ( 8 ), a spring ( 18 ) being arranged on the rotating element ( 20 ) in a manner such that the receptacle ( 9 ) is under spring force both in the operating position and in the rest position.    
   
   
       2 . The holder as claimed in  claim 1 , comprising a stop element ( 13 ) by means of which the position of the vision device can be set and fixed in a defined manner in the operating position.  
   
   
       3 . The holder as claimed in  claim 1  or  2 , wherein the spring ( 18 ) is fixed at one end to the rotating element ( 20 ) eccentrically relative to an axis ( 20   c ) of rotation about which the pivot movement takes place.  
   
   
       4 . The holder as claimed in any of the preceding claims wherein the spring is in the form of a tension, pressure or leg spring.  
   
   
       5 . The holder as claimed in  claim 3  or  4 , wherein a link-like engaging surface ( 46 ) for the spring ( 18 ) is provided on the rotating element.  
   
   
       6 . The holder for fixing at least one vision device, in particular a night vision device ( 2 ), on a head covering, such as a helmet ( 5 ), of a user ( 1 ), comprising 
 a support element ( 7 ) which can be fixed indirectly or directly to the helmet ( 5 )    an arm ( 8 ) coordinated with the support element ( 7 ), a receptacle ( 9 ) for the vision device being arranged so as to be pivotable about the arm ( 8 ), thus permitting a pivot movement of the vision device between an operating position and a rest position, in particular as claimed in any of the preceding claims, wherein the rotating element ( 20 ) non-rotatably connected to the receptacle ( 9 ) is coordinated with the arm ( 8 ), a damping element ( 28 ,  47 ,  48 ) being coordinated with the rotating element ( 20 ) in a manner such that, on movement of the vision device—at least on movement from the rest position to the operating position—the speed of movement is reduced at least over a partial range of the movement.    
   
   
       7 . The holder as claimed in  claim 6 , wherein the damping element, preferably in the form of a linear damper ( 47 ), is fixed at one end to the rotating element ( 20 ) eccentrically relative to an axis ( 20   c ) of rotation about which the pivot movement takes place.  
   
   
       8 . The holder as claimed in  claim 7 , wherein the damping element is in the form of a pneumatic spring, pneumatic cylinder or hydraulic shock absorber.  
   
   
       9 . The holder as claimed in  claim 6 , wherein the damping element ( 48 ) can be brought into operative connection with a limiting stop ( 50 ) corresponding to at least one end position of the movement of the vision device, the limiting stop ( 50 ) being arranged on the rotating element ( 20 ) eccentrically relative to an axis ( 20   c ) of rotation about which the pivot movement takes place.  
   
   
       10 . The holder as claimed in any of the preceding claims, wherein the arm ( 8 ) is arranged displaceably in the support element ( 7 ) and can be detachably fixed at any desired selectable position.  
   
   
       11 . The holder as claimed in a ny of the preceding claims, wherein the support element ( 7 ) is provided for holding two vision devices.  
   
   
       12 . The holder as claimed in any of the preceding claims, wherein the receptacle ( 9 ) for the vision device has a first adjusting element ( 10 ) for vertical positioning of the vision device relative to the position of the eye of the user ( 1 ) wearing the helmet ( 5 ) and in particular a second adjusting element ( 11 ) for the horizontal positioning of the vision device relative to the position of the eye of the user ( 1 ) wearing the helmet ( 5 ).  
   
   
       13 . The holder as claimed in  claim 12 , wherein the first adjusting element ( 10 ) is in the form of a slide—in particular a U-shaped slide—which is movable—in particular within the receptacle ( 9 )—and can be fixed in any desired position.  
   
   
       14 . The holder as claimed in  claim 13 , wherein the second adjusting element ( 11 ) is in the form of a slide which is movable—in particular movable within the first adjusting element ( 11 )—and can be fixed in any desired position.  
   
   
       15 . The holder as claimed in any of  claims 12  to  14 , wherein a coupling part ( 23 ) for the detachable fixing of the vision device is provided on one of the two adjusting elements ( 10 ,  11 ), preferably on the second adjusting element ( 11 ).
