Abstract: A guitar strap 10 includes an adjuster 13 by which the length of a second belt section 17 is adjusted. The adjuster 13 includes a base 31, a lever 32 manipulated to adjust the length of the second belt section 17, and a torsion spring 38 urging the lever 32 to pivot in a first direction. The second belt section 17 is clamped by the base 31 and the lever 32 due to urging force of the torsion spring 38. The second belt section 17 is released from a state clamped by the base 31 and the lever 32 by pivoting the lever 32 in a second direction, which is different from the first direction, against the urging force of the torsion spring 38.

The fixed member and the movable member each have a notch for receiving a pressing member that presses the friction plates against the surface of the notch. Each pressing member is fixed to the fixed member or movable member in a direction substantially parallel to the axis of the bolt. The friction plates are fixed between the notch and the pressing member.

Abstract: A drum includes a cylindrical body, a cylindrical head frame, which is fitted to the outer circumference of the body, a hoop located at the outer circumference of a head, lugs located at the outer circumference of the body, lug nuts, and lug bolts. A loosening prevention structure is located between the lower surface of the head of each lug bolt and the upper surface of the hoop. Each loosening prevention structure is formed by a washer with rubber according to a preferred embodiment. The washer with rubber is formed by an annular elastic body and a bowl-shaped cover. The elastic body is made of rubber. The cover includes a cylindrical portion, which covers the outer circumference of the elastic body. The cylindrical portion is formed to be shorter than the elastic body along the axial direction of the body.

Abstract: A carrier for holding a bass drum with two first connection mechanisms and one second connection mechanism. The second connection mechanism includes a connection member, which is arranged on the bass drum, and a slide member, which is arranged on the carrier. The distal end of the slide member is engaged with the connection member. Each first connection mechanism includes a hook receptacle, which is arranged on the bass drum and open in a downward direction, and a hook, which is arranged on the carrier and inserted in the receptacle.

Abstract: In a support device for a set of marching tenor drums arrayed in an arc shape of at least four drums, the device being held on the body of a player, two or three consecutive drums of the array, form at least one group. The device includes a holding mechanism for keeping the positions of the drums in each group constant relative to drums within the same group, and a turnable linking mechanism for linking the group and drums adjoining the group to be turnable relative to each other.

Abstract: A snare drum including a drum shell having an upper head and a lower head mounted thereon and a frame for holding a plurality of snare wires. The frame arranges the snare wires to be in contact with the lower head or to be spaced from the lower head. The snare drum includes a first latched member and a second latched member respectively located at opposite ends of the frame at an outer side the drum shell. An attachment mechanism is located on the drum shell for arranging the frame on a surface of the lower head. The attachment mechanism includes a first latching member and a second latching member arranged between the drum shell and the first and second latched members for separably latching the first and second latched members, respectively.

Abstract: A pedal is switched between a normal position and a low position, which is reached by depressing the pedal downward from the normal position with toes of a foot of a user. A pedal locking unit switches the pedal between a locked state in which the pedal is locked at the low position and an unlocked state in which the pedal is released from the locked state. A lock switch plate switches the pedal locking unit to the locked state. An unlock switch plate releases the pedal from the locked state of the pedal locking means. The lock and unlock switch plates are located beside the pedal to be operable by a heel of the foot.

Abstract: A head diaphragm adjustor for adjusting tension applied to upper and lower head diaphragms of a drum. A first bolt adjusts the tension applied to the upper head diaphragm. A second bolt adjusts the tension applied to the lower head diaphragm. A first meshed portion and a second meshed portion are respectively meshed with the first bolt and the second bolt and fixed to the shell. The upper portion of a rod is inserted in the first bolt in a manner independently rotatable relative to the first bolt. The lower portion of the rod is connected to the second bolt in a manner slidable relative to the second bolt and rotated integrally with the second bolt. The rod includes a cylindrical portion having a diameter greater than that of the upper portion of the rod. The first bolt abuts against the cylindrical portion.

Abstract: A tremolo operating mechanism comprising an arm socket secured onto a base plate, a resin bushing contained in the upper part of the arm socket, a torque adjusting screw screwed into the upper part of the arm socket to press the resin bushing, and an arm receiving resin nut which is engaged with the lower part of the arm socket and is also engaged with the lower end portion of a tremolo arm. The tremolo arm rotates on the shaft thereof to change the amount of screw engagement with the arm receiving resin nut and adjust the height of the tremolo arm from the body. As the torque adjusting screw rotates, the torque of the tremolo arm is adjusted by the resin bushing. Since the tremolo arm is supported by the resin bushing and the arm receiving resin nut, it does not interfere with the arm socket to improve operability.

Abstract: A stick for beating a percussion instrument. The instrument has an elastic component. A part of the stick forms a handle used for holding the stick. The elastic component is a part of the handle.

Abstract: A drum stand includes three support arms and rubber sleeves, each of which is arranged on one of the support arms. The rubber sleeves support a drum. Each rubber sleeve includes a first portion, which faces the side portion of the drum, and a second portion, which faces the bottom of the drum. The second portions are more easily bent than the first portions.

Abstract: A tremolo block extends from the back of a base plate into a space formed in a body. The tremolo block pivots with the base plate. The tremolo block has a hook portion at its distal end. The base is located at the back of the body. Engaging sections are formed at a rear portion of the base and open rearward. A moving member is detachably located at the engaging sections. The moving member is moved between an engaging position, at which the moving member engages with the engaging sections, and a standby position, at which the moving member is separated from the engaging sections. A pair of first springs connect the base with the tremolo block to urge the tremolo block forward against the tension of the strings. The urging force of the first springs is adjustable. A pair of second spring connect the base with the moving member. The second springs urge the moving member toward the engaging position. In a normal state, the second springs hold the moving member at the engaging position.
