Support element for a fan and fan equipped therewith

Abstract

The present invention relates to a support element ( 2 ) for holding a fan ( 1 ), in particular an axial fan, comprising a wall ring ( 4 ) for receiving the fan ( 1 ). The wall ring ( 4 ) has on its outer periphery a hinge ( 20 ) consisting of a first hinge part ( 22 ) that is connected to the wall ring ( 4 ) and a second hinge part ( 24 ) that can be pivoted about a hinge axis (X) relative to the first hinge part ( 22 ). The invention further relates to a fan ( 1 ) comprising such a support element ( 2 ).

         17 . The support element according to  claim 15 , characterized in that the two hinge parts ( 22 ,  24 ) have, on the one hand, flush bearing receptacles ( 28 ) in the direction of the hinge axis (X), and, on the other hand, bearing journals ( 30 ) that are joined in a joining direction that is parallel to the center axis of the wall ring ( 4 ). 
     
     
         18 . The support element according to  claim 17 , characterized in that the bearing receptacles ( 28 ) are configured as open bearing shells corresponding to the joining direction. 
     
     
         19 . The support element according to  claim 17 , characterized in that the second hinge part ( 24 ) has several journal projections ( 32 ) that extend perpendicular to the hinge axis (X) and that each have two opposing axial bearing journals ( 30 ), whereby each journal projection ( 32 ) intermeshes between two receiving projections ( 34 ) of the first hinge part ( 22 ) and, with its bearing journal ( 30 ), into opposite bearing receptacles ( 28 ) of the receiving projections ( 34 ). 
     
     
         20 . The support element according to  claim 17 , characterized in that the second hinge part ( 24 ), with bearing receptacles ( 36 ), additionally extends over axial bearing journals ( 38 ) of the first hinge part ( 22 ). 
     
     
         21 . The support element according to  claim 17 , characterized in that the joined hinge parts ( 22 ,  24 ) are secured against coming loose by latching means ( 40 ). 
     
     
         22 . The support element according to  claim 17 , characterized in that the hinge parts ( 22 ,  24 ) can only be joined and separated in a defined relative pivoted position. 
     
     
         23 . The support element according to  claim 15 , characterized in that the wall ring ( 4 ) can be attached to a mounting wall ( 10 ) in the area of a wall opening ( 12 ), for which purpose, the wall ring ( 4 ) preferably has an outer flange-like holding section ( 14 ) with mounting holes ( 16 ). 
     
     
         24 . The support element according to  claim 23 , characterized in that the second hinge part ( 24 ) is fastened to the mounting wall ( 12 ) in the area next to the wall opening ( 12 ), for which purpose the second hinge part ( 24 ) has mounting holes ( 46 ). 
     
     
         25 . The support element according to  claim 15 , characterized in that, especially in a middle area of the first hinge part ( 22 ) as seen in the circumferential direction, the wall ring ( 4 ) has at least one cable insertion opening ( 48 ).
