Abstract: A drum rim includes inner and outer rim portions. The outer rim portion is smoothly tapered to provide comfort to the hands of the player. An inner rim portion is arranged to engage the drum skin at a position that has a diameter which is less than the central diameter of the drum wire.

Abstract: A tambourine is fabricated from a single piece frame having two hinges which divide the frame into a central section and two end sections. As assembled the frame is bent at the hinges and curved so that the two end sections can be joined by a connecting member. The jingles are preferably mounted by grooves which intersect jingle slots and are arranged on opposite sides of the frame to retain the jingle mounting pin.

Abstract: A ventilated rack case for alternatively transporting and operating a rack mountable unit of electronic equipment includes an inner rectangular frame, which is open at the front and back, shock absorbing material, e.g. foam, surrounding the frame, and an outer cover over the foam. For ventilation, cutouts are provided in the foam and frame and a protective screen is secured in the openings. The cover includes front and back flaps for selectively closing the front and back openings of the frame. A top ventilation flap is configured to cooperate with the cutouts to provide ventilation. The flaps can be closed for storing and transporting the rack, and opened for use to allow access to the control panels and proper ventilation of the electronic equipment without removal from the case.

Abstract: A percussion instrument comprises an oblong plastic block having a generally rectangular block portion with a front face and top and bottom surfaces, and a flange extending outwardly from the sides and rear. An elongated slot in the front face extends rearwardly to the rear flange, and laterally between the side flanges. The block has a raised ridge on the top face adjacent the front face for striking. In addition, landings are formed in the flanges which, together with a cooperating bracket assembly, act as a means for mounting the block.

Abstract: A portable and foldable stand for musical instruments includes a pair of spaced apart supports each including a tubular main leg having a pivot collar, a brace leg, a brace, a pin for joining one end of the brace to the brace leg, and a latch for releasably attaching the brace to the main leg. The brace leg is pivotally linked at one of its ends to the pivot collar of the main leg and is joined to one end of the brace by the pin. The other end of the brace is releasably attached to the main leg by the latch means. A pivot is joined to the main leg, and an upper segment is joined to the pivot means. At least two cross members are provided each one including a releasable clamping sleeve for releasably clamping each cross member to each support. The clamping sleeve is releasably clampable and slidable on the upper segment and the pivot, thereby linking the pair of supports.

Abstract: A clamping device for releasably mounting an instrument accessory includes a clamp member having an elongated channel formed therein, a worm shaft rotatably retained in the channel, a control device for rotating the worm shaft, a movable clamping jaw received on the shaft for reciprocal movement along the channel upon rotation of the shaft, and a fixed clamping jaw disposed adjacent to one end of the channel for cooperation with the movable clamping jaw. A support arm for supporting an instrument accessory is also provided which is mounted on the clamp member in a substantially universally-adjustable manner. The clamping device is especially intended for releasably mounting microphones and percussion accessories on the rims of drums.

Abstract: A percussion instrument includes a sound chamber having a cavity therein with at least one opening thereinto, support means secured to the chamber within the cavity, a resilient, elongated member disposed within the cavity of the chamber, one end of which is free-standing and the other end of which is coupled to the support means, a knocker secured to the free end of the resilient member, and a vibratory, elongated rod which is secured to the sound chamber. The rod includes a handgrip along one portion of its length for imparting sustained vibrations to the resilient member and, in turn, the knocker, so that the knocker will strike the walls of the sound chamber to thereby produce a percussion sound. The instrument is particularly suitable for simulating the sound of a jawbone percussion instrument, used for Latin American music.
