Abstract: A drum pedal assembly has a base plate adapted to sit on the floor and having an outer end adapted to be juxtaposed with a drum and an opposite inner end and a pedal pivoted on the base-plate inner end. A pair of posts having upper and lower ends are releasably fixed at the base-plate outer end with the posts generally parallel and vertical. Respective bearings on the post upper ends support a shaft carrying a beater mount. Mechanism links the pedal to the shaft for rotation of the shaft on depression of the pedal.

Abstract: A drum having an annular rim is connected to a pedal assembly by a clamp having an outer clamp part engaging an outer surface of the rim only at a pair of locations axially spaced along the rim and an inner clamp part generally aligned with the outer part and engaging an inner surface of the rim only at a pair of locations axially spaced along the rim and lying between the locations of the outer clamp part. The clamp parts are pressed toward each other against the respective surfaces of the rim, and a coupling secures the clamp parts to the pedal assembly.

Abstract: The invention relates to a carrying and/or holding device for musical percussion instruments, particularly with an attachment for an instrument, such as a tom-tom drum, wherein the attachment is fastened by means of an upper bearing and a lower bearing to the kettle of a bass drum in a vibration damping manner.

Abstract: In order to simplify the design of a clamping device (1), in particular for securing an axially displaceable rod (3) in optional adjustment positions, in which a rolling body (17) is supported at a housing (5) enclosing it for clamping purposes, the rolling body (17) is arranged in a lever head (9) of a lever (6) having at its end remote of the lever head (9) a push button (11) which is guided out through the housing (5) and the rolling body (17) contacts a portion of the wall of the housing (5) constructed on its inner side as an oblique plane (19).

Abstract: A tensioning device for the skins of percussion instruments includes a plurality of bearing brackets which are provided with threads and are arranged distributed over the circumference of the instrument shell. Tensioning screws are adjustably mounted in the bearing brackets and act on a hoop for holding the skin. A clamping piece of an elastomer material which surrounds each tensioning screw serves to secure the screws automatically in each tensioning position relative to the bearing bracket or a thread in the bearing bracket. The clamping piece is mounted so as to be in positively locking engagement with a structural component of the tensioning device.

Abstract: A stand or tripod for receiving and holding objects, particularly musical instruments and/or accessories includes a center shaft and adjustable legs which are slidably mounted on the center shaft, wherein at least one of the legs can be swung about the center shaft. The legs are connected to sleeves arranged at the bottom end and at the top end of the shaft, wherein each sleeve is composed of a pair of sleeve members which are concentrically nested into one another.

Abstract: A swivel joint for an essentially rod-shaped object, such as, a tripod, a leg or a similar support or holder for devices, particularly for musical percussion instruments, includes two joint members which are movable relative to each other and can be locked by a clamping device. The clamping device is constructed in such a way that it can simultaneously be used for clamping the rod-shaped object. In an annular end face facing away from the stationary joint member, the ring has diametrically oppositely arranged prismatic radial recesses which correspond to openings in the wall of the sleeve. When the radial recesses and the wall openings are in an aligned position, the rod-shaped object can be inserted into the swivel joint, such that the rod-shaped object extends through the radial recesses of the ring and the axial wall openings of the sleeve.

Abstract: A membranophone includes a principal skin or head skin and a secondary skin as well as a skin tightening device and/or tuning device. The skin tightening and/or tuning device includes rod-shaped tightening elements at least for the head skin, wherein the tightening elements are arranged uniformly distributed over the outer circumference of the resonator shell of the membranophone, and wherein the tightening elements are supported by support members fastened to the resonator shell, on the one hand, and the tightening elements adjustably act through threaded members on the tightening hoop for the skin or skins, on the other hand. Damping members are arranged between the support members and the resonator shell or kettle. The skin or skins are held by winding hoops and can be tightened and, thus, tuned by means of the winding hoops and the tightening hoops relative to the opening rim of the resonator shell.

Abstract: A resonator body for musical drum instruments is formed by shaping and gluing together several superimposed material layers, particularly wood veneer layers or plywood layers. The resonator body has the shape of a hollow cylinder. Abutting edges of the individual material layers extend in the direction of the resonator body axis and the abutting edges of the individual material layers are offset relative to each other in circumferential direction of the hollow cylinder. In order to ensure that the abutting edges are permanently and securely held together, the abutting edges of at least the outer material layer, preferably of all material layers, have contours which are toothed and complementary relative to each other and inter-engage in circumferential direction of the hollow cylinder.
