Fastening device for an inserting element that can be inserted into an insertion opening of a base plate

Abstract

A fastening device for an inserting element that can be inserted into an inserting opening of a base plate. The inserting element can be fastened to the base plate by at least one holding device. The holding device has a basic component ( 9 ) that can be firmly fixed to the inserting element and a hinged component designed as a U-shaped bracket. A bar of the U-shaped bracket near an upper side plate has a guide end directed toward the swivel axis of the U-shaped bracket which can mesh with flat locking grooves on the basic component. The locking grooves are arranged such that the holding device can be locked in its operating position and also in an inserting position that is swiveled from this operating position by 90°.

1 . Fastening device for an inserting element that can be inserted into an inserting opening of a base plate and lies with its free end rested on the surface of the base plate, the inserting element can be fastened to the base plate by at least one holding device that has a basic component that can be firmly affixed to the inserting element and a component that is hinged to this basic component and that underlaps the lower side of the base plate by applying a holding pressure by means of a screw, the hinged component is designed as a U-shaped bracket including upper and lower sidepieces that are penetrated by the screw and wherein the upper sidepiece is connected to the basic component by the screw, at least on one side of the lower sidepiece extends laterally an attachment that is designed as an arm underlapping the lower side of the base plate, wherein a bar of the U-shaped bracket of the hinged component of a said at least one holding device close to the upper side piece of the U-shaped bracket has an a guide end that is directed toward the swivel axis of the bar, the guide end can mesh with the flat locking grooves on the basic component that are arranged such that the holding device can be locked in its operating position and also in an inserting position that is swiveled by 90° from the operating position.  
   
   
       2 . Fastening device in accordance with  claim 1  wherein said guide end is the free end of a guide that is cut out from the bar, the guide stretches essentially parallel to the longitudinal direction of the bar and enables the guide end to protrude elastically from said flat locking grooves by applying pressure for swiveling the bar.  
   
   
       3 . Fastening device in accordance with  claim 2  wherein the hinged component that is designed as a U-shaped bracket is hinged to a flap shaped section that sticks out from the basic component, the flap-shaped section has a recess that is provided with a thread that works together with the thread of the screw.  
   
   
       4 . Fastening device in accordance with  claim 1  wherein the basic component has a section that serves for fastening to the inserting component, the flap sticks out from the lower edge of this section, and the swiveling component is hinged to the flap.
