ABSTRACT:
The hinge joint of a tom-tom holder for maintaining an adjustable angle relationship between a support bar mounted on a bass drum and a tom-tom holding arm adapted to hold a tom-tom comprises a housing connected to the support bar and a bushing connected to the tom-tom holding arm. A resilient band extends along the inner periphery of a cylinder defined in the housing and has one end fixedly secured in the cylinder inner surface and has the other end biased by a band fastening screw threaded in a threaded bore formed in the housing tangential to the cylinder bore. The annular projection of the bushing is received in the cylindrical opening formed by the resilient band. The annular projection and the cylinder bore are maintained in co-axial relationship by an aligning bolt and ring unit. By loosening the band fastening screw, the annular inner face of the disk portion of the bushing and the adjacent end face of the cylinder in the housing are maintained in slidable contact. The tom-tom holding arm can be manually adjusted to a desired angle. Thereafter, by fastening the band fastening screw, the bushing annular projection is fastened about the outer periphery thereof by the resilient band so as to secure the bushing to the housing to maintain the tom-tom holding arm at a desired and adjusted angle with respect to the support bar.
