Abstract
A drum head tension control device has a mounting post, two connectors and two adjusting bolts. The mounting post is mounted on a cylindrical shell of a drum between two drum hoops having multiple mounting holes. The connectors are pivotally attached to the mounting post and have a proximal end, a distal end and a threaded hole. The proximal end is attached to the mounting post, and the threaded hole is formed coaxially in the distal end. The adjusting bolts extend respectively through mounting holes in opposite drum hoops and screw respectively into the threaded holes of the connectors to adjust tension on the drum heads.
Claims5
A drum head tension control device mounted on an outside surface of a cylindrical drum shell (40) between two drum hoops (50), the drum head tension control device comprising:
- a mounting post (10) adapted to be mounted on a cylindrical drum shell (40) and having
- a proximal end adapted to be attached to the cylindrical drum shell (40);
- and
- a distal end;
- two connectors (20) being tubular and attached pivotally to the mounting post (10), and each connector (20) having
- open distal end;
- a closed proximal end attached pivotally to the mounting post (10);
- and
- a threaded hole (22) defined coaxially through the open distal end;
- and
- two adjusting bolts (30) being threaded, adapted to be mounted respectively through holes respectively in opposite drum hoops (50) and screwing respectively into the threaded holes (22) in the connectors (20), and each adjusting bolt (30) having
- a distal end;
- a proximal end;
- a flange (31) formed around the adjusting bolt (30) near the distal end for abutting and holding the corresponding drum hoop (50).
