Abstract
A drum tensioning device is provided. The drum tensioning device can include an insert having a flange and a shank. The shank can be configured to engage a tension rod. The tensioning device can also include a casing having a mount configured to receive a connecting member to secure the casing to a shell of the drum. The casing can further include an opening formed in the casing through which the shank of the insert extends and a recess formed on an inner surface of the casing configured to retain the flange of the insert while permitting for radial and axial movement of the shank relative to the opening.
Claims20
A drum tensioning device, comprising:
- A) an insert comprising a flange and a shank, wherein the shank is configured to engage a tension rod;
- and
- B) a casing comprising
- i) a mount configured to receive a connecting member to secure the casing to a shell of the drum,
- ii) an opening formed in the casing through which the shank of the insert extends, and
- iii) a recess formed on an inner surface of the casing configured to retain the flange of the insert while permitting for radial and axial movement of the shank relative to the opening.
A drum, comprising:
- A) a shell having a first end and a second end, wherein the first end and the second end are open in the axial direction;
- B) a drum skin overlaying said first end;
- C) a hoop securing the drum skin to said first end;
- D) a tension rod coupled to said hoop;
- and
- E) a tensioning device coupled to said shell and configured to act on the hoop to provide tension to said drum skin, the tensioning device comprising
- i) an insert comprising a flange and a shank, wherein said shank receives said tension rod, and
- ii) a casing comprising
- a) a mount secured to said shell,
- b) an opening through which said shank extends;
- and
- c) a recess formed on an inner surface of said casing to retain said flange and permit radial and axial movement of said shank relative to the opening.
