Device for maintaining and ejecting a compact disc on a support base

Abstract

This device comprising engaging and retaining means ( 1 b ), ( 1 c ), ( 1 d ), ( 1 e ) collaborating with the central hole in the disc, said disc engaging and retaining means being formed as an overhang over a circular central region ( 1 ) exhibited by the base ( 1 ), is notable in that the region ( 1 a ) has arrangements able, when finger pressure is applied to said means ( 1 b ), to allow them to retract in part only so as to cause simultaneous controlled tilting of the disc corresponding to its partial release from the base ( 1 ) so that it can be grasped by hand at the released part.

1 . A device for maintaining and ejecting a compact disc on a support base comprising engaging and retaining means ( 1   b ), ( 1   c ), ( 1   d ), ( 1   e ) collaborating with the central hole in the disc, said disc engaging and retaining means being formed as an overhang over a circular central region ( 1   a ) exhibited by the base ( 1 ), characterized in that the region ( 1   a ) has arrangements able, when finger pressure is applied to said means ( 1   b ), to allow them to retract in part only so as to cause simultaneous controlled tilting of the disc corresponding to its partial release from the base ( 1 ) so that it can be grasped by hand at the released part.  
     
     
         2 . The device as claimed in  claim 1 , characterized in that the base ( 1 ) has, on the side of the tilting of the disc, a bearing profile ( 11 ) able to hold said disc in a tilted position.  
     
     
         3 . The device as claimed in  claim 2 , characterized in that the bearing profile ( 11 ) consists of a substantially elliptical rim collaborating with a part of the circular edge of the disc.  
     
     
         4 . The device as claimed in  claim 3 , characterized in that the substantially elliptical rim is connected to the base ( 1 ) by a slot ( 111 ) allowing partial engagement and abutment of the corresponding circular edge of the disc.  
     
     
         5 . The device as claimed in  claim 1 , characterized in that the arrangements of the central region ( 1   a ) consist of at least one bearing and stiffening ( 1   h - 1   i ) suitably positioned with respect to cut-outs, in combination with the disc engaging and retaining means ( 1   b ), ( 1   c ), ( 1   d ) and ( 1   e ), said central region ( 1   a ) standing up above the base ( 1 ) thereby creating a circular recess so as to be deformed elastically.  
     
     
         6 . The device as claimed in claims  1  and  5 , characterized in that the disc engaging and retaining means consist of a push-button ( 1   b ) and tongues ( 1   c ), ( 1   d ) and ( 1   e ), said button ( 1   b ) is connected to a central hole ( 1   f ) of the raised region ( 1   a ) by tabs ( 1   b   1 ), ( 1   b   2 ), ( 1   b   3 ) between which are situated said tongues ( 1   c ), ( 1   d ), ( 1   e ) formed from cut-outs ( 1   g ) of said raised region ( 1   a ) so as to be elastically deformable, at least one of the tongues ( 1   c ) is rendered rigid by the bearing means ( 1   h - 1   i ) suitably positioned with respect to the cut-outs ( 1   g ).  
     
     
         7 . The device as claimed in  claim 6 , characterized in that the bearing and stiffening means, singular or plural, consist of ribs positioned in relationship with at least one of the tongues ( 1   c ) and/or part of the push-button ( 1   b ).  
     
     
         8 . The device as claimed in  claim 7 , characterized in that the bearing and stiffening rib ( 1   h ) of the tongue ( 1   c ) is formed so that it overhangs the recessed part ( 1   a   3 ) of the raised central region ( 1   a ) so that it lies in the same bearing plane as the base, said rib ( 1   h ) being directed along the central axis of symmetry of the cut-outs ( 1   g ) from which cut-outs said tongue is formed.  
     
     
         9 . The device as claimed in  claim 7 , characterized in that the bearing and stiffening rib ( 1   i ) of part of the button ( 1   b ) is formed so that it overhangs the recessed part ( 1   a   3 ) of the raised central region ( 1   a ) so that it lies in the same bearing plane as the base, said rib ( 1   i ) lying facing and near one of the connecting tabs of said button ( 1   b ), cut-outs formed in the thickness of the raised region partially surrounding said rib.  
     
     
         10 . The device as claimed in  claim 7 , characterized in that the ribs ( 1   h - 1   i ) are diametrically opposed.  
     
     
         11 . The device as claimed in  claim 6 , characterized in that the push-button ( 1   b ) has three connecting tabs ( 1   b   1 ), ( 1   b   2 ), ( 1   b   3 ) uniformly distributed around the circumference with a 120° offset, each of the tongues ( 1   c ), ( 1   d ), ( 1   e ) being arranged along the bisector of the angle delimited by two tabs so as to be uniformly distributed on a circumference with a 120° offset.
