Abstract
A drum assembly that includes a circular frame member that defines a frame opening therein, an upper drum head member secured to the frame member and spanning the frame opening, a lower drum head member positioned below the upper drum head member, secured to the frame member and spanning the frame opening, and a threaded rod assembly extending between the upper drum head member and the lower drum head member. The threaded rod assembly includes an upper threaded member that is threadingly engaged with the upper drum head member. Rotation of the upper threaded member in a predetermined direction moves the upper drum head member away from the lower drum head member, such that tension is increased in the upper drum head member.
Claims16
A drum assembly comprising:
- a frame member that defines a frame opening therein, wherein the frame member defines a central axis, wherein the frame member defines a hoop channel that includes a ring member therein,
- an upper drum head member secured to the frame member and at least partially spanning the frame opening, wherein the upper drum head member includes an outer circumference portion,
- a lower drum head member positioned below the upper drum head member, secured to the frame member and at least partially spanning the frame opening, wherein the lower drum head member includes an outer circumference portion, wherein the outer circumference portion of the upper drum head member and the outer circumference portion of the lower drum head member are received in the hoop channel and at least partially surround the ring member, and
- a threaded rod assembly extending co-axially with the central axis between the upper drum head member and the lower drum head member, wherein the threaded rod assembly includes an upper threaded member that is threadingly engaged with the upper drum head member, and wherein rotation of the upper threaded member in a predetermined direction increases or decreases the tension in the upper drum head member.
A drum assembly comprising:
- a frame member that defines a frame opening therein,
- an upper drum head member secured to the frame member and at least partially spanning the frame opening,
- a lower drum head member positioned below the upper drum head member, secured to the frame member and at least partially spanning the frame opening, wherein the frame member includes an inner wall, a bottom wall, an outer wall and an upper wall that cooperate to at least partially define a hoop channel, wherein a gap is defined between the inner wall and the upper wall, and wherein the upper drum head member and lower drum head member extend through the gap and into the hoop channel, and
- a threaded rod assembly extending between the upper drum head member and the lower drum head member, wherein the threaded rod assembly includes an upper threaded member that is threadingly engaged with the upper drum head member, and wherein rotation of the upper threaded member in a predetermined direction increases or decreases the tension in the upper drum head member.
A drum assembly comprising:
- a frame member that defines a frame opening therein,
- an upper drum head member secured to the frame member and at least partially spanning the frame opening,
- a lower drum head member positioned below the upper drum head member, secured to the frame member and at least partially spanning the frame opening, wherein the lower drum head member includes a sleeve assembly that includes a seat portion, and
- a threaded rod assembly extending between the upper drum head member and the lower drum head member, wherein the threaded rod assembly includes an upper threaded member that is threadingly engaged with the upper drum head member, and wherein rotation of the upper threaded member in a predetermined direction increases or decreases the tension in the upper drum head member, wherein the upper threaded member is seated on the seat portion, wherein the upper threaded member is rotatable with respect to the sleeve assembly.
A drum assembly comprising:
- a frame member that defines a frame opening therein, wherein the frame member defines a central axis, wherein the frame member defines a hoop channel that includes a ring member therein,
- an upper drum head member secured to the frame member and spanning the frame opening, wherein the upper drum head member includes an outer circumference portion, wherein the outer circumference portion of the upper drum head member is received in the hoop channel and at least partially surrounds the ring member,
- a threaded rod assembly extending co-axially with the central axis that includes an upper threaded member and a lower member, wherein the upper threaded member is threadingly engaged with the upper drum head member and is rotatable with respect to the lower member,
- wherein rotation of the upper threaded member in a predetermined direction increases or decreases the tension in the upper drum head member.
A drum assembly comprising:
- a frame member that defines a frame opening therein, wherein the frame member defines a central axis, and wherein the frame member defines a hoop channel that includes a ring member therein,
- an upper drum head member secured to the frame member and spanning the frame opening, wherein the upper drum head member includes an upper threaded receiver, and wherein the upper drum head member includes an outer circumference portion,
- a lower drum head member positioned below the upper drum head member, secured to the frame member and spanning the frame opening, wherein the lower drum head member includes an outer circumference portion, wherein the outer circumference portion of the upper drum head member and the outer circumference portion of the lower drum head member are received in the hoop channel and at least partially surround the ring member, wherein the lower drum head member includes a lower threaded receiver, wherein the upper and lower threaded receivers are co-axial with the central axis and are configured to receive a threaded rod assembly that includes an upper threaded member that is threadingly engaged and co-axial with the upper threaded receiver, such that rotation of the upper threaded member in a predetermined direction moves at least a portion of the upper drum head member away from the lower drum head member to increase tension in the upper drum head member.
