Fixing device for fixing an actuation device with push-push kinematics

Abstract

Fixing device for fixing an actuation device with push-push kinematics on a component of a motor vehicle, in particular a fuel filler housing, comprising an at least in sections cylindrically formed housing of the actuation device with at least one guiding element provided on the outer surface of the housing and at least one locking recess provided also on the outer surface of the housing, further comprising an opening in the component, into which opening the actuation device can be inserted with its housing, and at least one guiding element provided on the component starting from the opening in the insertion direction of the housing, wherein the guiding element of the actuation device and the guiding element of the component, upon insertion of the actuation device into the opening, cooperate such that the actuation device is guided into the opening in at least one predetermined rotational position, and further comprising at least one locking projection provided on the component starting from the opening in the insertion direction of the housing, wherein the locking projection of the component and the locking recess of the housing lock with each other upon the actuation device being inserted fully into the opening in the predetermined rotational position, and thus fix the actuation device on the component, and wherein the locking can be released again by rotating of the actuation device out of the predetermined rotational position.

1 . Fixing device for fixing an actuation device with push-push kinematics on a component of a motor vehicle, in particular a fuel filler housing,
 comprising an at least in sections cylindrically formed housing of the actuation device with at least one guiding element provided on the outer surface of the housing and at least one locking recess provided also on the outer surface of the housing,   further comprising an opening in the component, into which opening the actuation device can be inserted with its housing, and   at least one guiding element provided on the component starting from the opening in the insertion direction of the housing,   wherein the guiding element of the actuation device and the guiding element of the component, upon insertion of the actuation device into the opening cooperate such that the actuation device is guided into the opening in at least one predetermined rotational position, and   further comprising at least one locking projection provided on the component starting from the opening in the insertion direction of the housing,   wherein the locking projection of the component and the locking recess of the housing lock with each other upon the actuation device being inserted fully into the opening in the predetermined rotational position, and thus fix the actuation device on the component, and   wherein the locking can be released again by rotating of the actuation device out of the predetermined rotational position.   
     
     
         2 . Fixing device according to  claim 1 , characterized in that the at least one guiding element of the actuation device is at least one guiding projection provided on the outer surface of the housing, and that the at least one guiding element of the component is at least one guiding groove, said guiding groove extends starting from the opening in the insertion direction of the housing. 
     
     
         3 . Fixing device according to  claim 1 , characterized in that the component comprises at least two hollow cylinder sections each with at least one locking projection, and each, starting from the rim of the opening extending in the insertion direction of the housing and each being elastically resilient at least at their end facing away from the rim of the opening, and in that the actuation device comprises in each case at least two locking recesses corresponding to the locking projections of the hollow cylinder sections. 
     
     
         4 . Fixing device according to  claim 3 , characterized in that the locking projections are each provided in the area of the end of the hollow cylinder sections, which is facing away from the rim of the opening. 
     
     
         5 . Fixing device according to  claim 3 , characterized in that the hollow cylinder sections are connected with the rim of the opening and are free at their end facing away from the rim of the opening. 
     
     
         6 . Fixing device according to  claim 2 , characterized in that a hollow cylindrical guiding lug extends starting from the rim of the opening in the insertion direction of the housing, and in that starting from said hollow cylindrical guiding lug the hollow cylinder sections extend in the insertion direction of the housing and, in that the at least one guiding groove is provided in the hollow cylindrical guiding lug. 
     
     
         7 . Fixing device according to  claim 1 , characterized in that on the upper side of the housing the actuation device comprises a hood of flexible material being foldable in the axial direction and, in that the component comprises a circumferential collar at the rim of the opening, on which collar the hood circumferentially abuts in the state fixed to the component.
