Convertible drumhead

A drumhead for use in conjunction with a drum shell wherein an annular hoop is employed in stressed relation with said drumhead for use in attaching and fixedly securing said drumhead to said drum shell and tensioning the drumhead to an appropriate tonality, comprising:

• a material for constituting a drumming surface,
• a first supporting peripheral wall member having a top section, a bottom section, an inside surface and an outside surface, said first supporting peripheral wall member being integrally formed circumferentially with a drum surface with an orientation generally normal to said surface and having a plurality of spaced openings disposed generally around the bottom section, and
• a first liquid means curable to a rigid state comprising in said rigid state an annual shoulder disposed circumferentially and generally in abutting seal-tight relation against the outside surface of said first supporting peripheral wall member, said annular shoulder including means integrally formed therewith for fixedly anchoring said shoulder to said peripheral wall member to enable said shoulder to withstand the stress forces resulting from the tensioned engagement with said annular hoop.

A drumhead to be held by hand and played independently of a drum shell comprising,

• a material for constituting a drumming surface,
• a supporting peripheral wall member having a top section, a bottom section, an inside surface and an outside surface, said supporting peripheral wall member being integrally formed circumferentially of said drumming surface with an orientation generally normal to said surface and having a plurality of spaced openings disposed generally around the bottom section,
• a first means cured from a liquid to a rigid state comprising in said rigid state an annular shoulder protruding outwardly from said supporting peripheral wall member and disposed circumferentially and in abutting seal-tight relation against the outside surface of said supporting peripheral wall member, said annular shoulder including means integrally formed therewith for fixedly anchoring said annular shoulder to said supporting peripheral wall member, said annular shoulder having a horizontally extending top surface comprising an annular seat to engage and be gripped by a player's hand.

In combination with a drum shell having a circumferential side wall with a top rim and a bottom rim defined at opposite ends of said side wall, a musical instrument in the form of a convertible drumhead adapted to be installed in direction contacting engagement with or upon one or both of said rims, comprising

• a material for constituting a drumming surface having an exposed annular top rim, said drumming surface and said exposed annular top rim being aligned along a common plane.
• a peripheral wall member having a top section, a bottom section, an inside surface and an outside surface, said peripheral wall member having an orientation generally normal to the drumming surface and being integrally formed circumferentially thereof, and
• an annular shoulder disposed circumferentially and generally about the bottom section of said peripheral wall member, said annular shoulder adapted to engage a corresponding annular hoop means for use in attaching and fixedly securing said drumhead to a drum shell and tensioning the drumhead to an appropriate tonality.

A drumhead to be held by hand and played independently of a drum shell comprising,

• a material for constituting a drumming surface having an exposed annular top rim, said drumming surface and said exposed annular top rim being aligned along a common plane,
• a supporting peripheral wall member having a top section, a bottom section, an inside surface and an outside surface, said supporting peripheral wall member having an orientation generally normal to the drumming surface and being integrally formed circumferentially thereof, and
• an annular peripheral wall member protruding outwardly from said supporting peripheral wall member and disposed circumferentially and generally about the bottom section of said supporting peripheral wall member, said annular peripheral wall member having a horizontally extending top surface comprising an annular seat to engage the hand of and be held by a player.
