Flying Disk With Removable Trampoline Portion

A sports activity device adapted to be both a flying disc and a racquet-like apparatus, comprising:

• an annular outer ring having an outer surface and an annular groove in the outer surface;
• an annular inner ring detachably connectable with the outer ring and defining a central opening in the inner ring;
• and
• a flexible material secured to the inner ring and extending across the central opening of the inner ring and creating a trampoline surface that stretches across the central opening of the inner ring;
• the inner ring being received in the groove of the outer ring, to detachably connect the inner ring and thereby the flexible material to the outer ring;
• the groove having an irregular configuration defined by a series of side surfaces intersecting with each other and with the outer surface of the outer ring;
• the inner ring having an irregular configuration including a plurality of relatively movable flanges;
• the flanges having a first position relative to each other when in a free state outside the groove and, when in the first position, being spaced apart from each other by a first distance;
• the flanges having a second position relative to each other when they are partially but not fully inserted into the groove and, when in the second position, being spaced apart from each other by a second distance that is less than the first distance;
• the flanges having a third position relative to each other when they are fully inserted into the groove and, when in the third position, being spaced apart from each other by a third distance that is greater than the second distance;
• the flanges when fully inserted in the groove and when in the third position engaging at least one of the side surfaces of the groove and resisting removal of the inner ring from the groove.

A sports activity device adapted to be both a flying disc and a racquet-like apparatus, comprising:

• an annular outer ring centered on an axis and having an outer surface including an upper side surface of the outer ring, the outer ring also having an annular groove in the outer surface, the groove being centered on the axis and extending axially downward from the upper side surface of the outer ring;
• an annular inner ring centered on the axis and detachably connected with the outer ring and defining a central opening in the inner ring;
• and
• a flexible material secured to the inner ring and extending across the central opening of the inner ring and creating a trampoline surface that stretches across the central opening of the inner ring;
• the inner ring being received in the groove of the outer ring, to detachably connect the inner ring and thereby the flexible material to the outer ring;
• the groove including an undercut in the material of the outer ring that is located on the axially outer side of the groove, the undercut being located a substantially constant distance from the upper side surface of the outer ring at all points circumferentially around the axis;
• and
• the inner ring including a portion that engages in the undercut and resists removal of the inner ring from the groove.
