  • Patent number: 11763785
    Abstract: A percussion instrument pedal apparatus includes a footboard and a transmission mechanism connectable to the footboard. A beater, which is mountable to a pivot shaft, strikes a bass drum in response to pivoting of the pivot shaft. The transmission mechanism includes two adjusting mechanisms for adjusting the motion characteristics of the footboard and for adjusting the footboard angle. The transmission mechanism can be interchanged with different types, such as a chain-drive transmission mechanism and a direct-drive transmission mechanism.

  • Patent number: 11670265
    Abstract: Provided is a stand for a musical instrument, the stand including a pole in the shape of a stick extending in one direction, and a plurality of legs extending from the pole and arranged in a circumferential direction of the pole. At least one of the plurality of legs is a rotatable leg attached to the pole so as to be capable of rotating about a central axis of the pole. At least one of the plurality of legs is an offset leg held by the pole such that a longitudinal axis of the offset leg is apart from the central axis of the pole without crossing the central axis when viewed in an axial direction of the pole.

  • Patent number: 10529306
    Abstract: Pivot shaft support members, formed as component parts separate from support posts of a frame of a pedal apparatus, are mounted on respective upper ends of the support posts, and the pivot shaft support members pivotably support the opposite ends of a pivot shaft for a beater rod. A heel section is provided on a rear end portion of an under plate of the pedal apparatus, and a pair of left and right hinge support members, formed as component parts separate from the heel section, are mounted to the heel section. The hinge support members pivotably support the opposite ends of a pivot shaft of a hinge section of a foot board. Because the pivot shaft support members and the hinge support members are separate component parts from the frame, mounted positions of these support members can be adjusted finely during mounting, to the frame, of the support members.

  • Patent number: 10360881
    Abstract: A drum foot pedal apparatus includes: a coil spring imparting resilient self-returning force to a foot board; a rod member (or an adjusting bolt) supported by a support section provided on a support post member; and a tension adjustment mechanism provided between the coil spring and the rod member. The tension adjustment mechanism includes a connection position adjustment section that interconnects the lower end of the coil spring and the rod member above the support post member, and that is constructed to permit adjustment of a connection position between the lower end of the coil spring and the rod member or the adjusting bolt at a position above the support section. Thus, it is possible to effectively prevent frictional wear of component parts and generation of noise and achieve an enhanced operability in the tension adjustment, with a simple construction having a minimized number of component parts.

  • Patent number: 9691367
    Abstract: A drum foot pedal apparatus is provided which can effectively prevent, by a spike member, positional displacement of the apparatus from occurring due to depression of a foot board and permits adjustment of a projected amount of the spike member with a simple construction. The apparatus includes: a base member fixed at one end to a frame section and fixed at the other end to a heel member, thereby interconnecting the frame section and the heel member; and a spike member provided on the base member in such a manner as to be projectable downward beyond the lower surface of the base member. The spike member is disposed at a position where it does not positionally overlap the foot board, and the spike member is constructed so that the projected amount of the spike member is adjustable by an operation from above the upper surface of the foot board.

  • Patent number: 9685146
    Abstract: Disclosed are a drum beater and a drum foot pedal apparatus which are simple in construction with reduced numbers of component parts and yet allow weight adjustment of the beater to be performed promptly and reliably through a mere manual operation without using any tool, and which include: a beater head for striking a drum; a beater rod having the beater head mounted thereon; a retention member mounted on the beater rod, through a mere manual operation without using any tool, in such a manner that it is axially displaceable relative to the beater rod; a spring normally biasing the retention member toward the beater rod; and a weight member held sandwiched between the retention member and the beater head by the biasing force of the spring.

  • Publication number: 20170110098
    Abstract: Disclosed is a percussion instrument pedal apparatus where a transmission mechanism is connectable to a foot board without use of an engaging member projecting from the reverse side of the foot board. The pedal apparatus includes: a foot board; a beater mounted on a pivot shaft and capable of striking a bass drum in response to pivoting of the pivot shaft; a chain member having a pivot-shaft connected section provided on one end thereof to transmit pivoting force to the pivot shaft; and a connection member pivotably mounted at one end to the distal end of the foot board and connected at the other end to the chain member, the connection member transmitting, to the chain member, pivoting force responsive to depression of the foot board. The pivoting force transmitted to the chain member is then transmitted from the chain member to the pivot shaft.

  • Patent number: 8084676
    Abstract: The distal structure of a leg for a musical instrument stand is constituted of a spike member installed inside the storage of a case having a ground portion whose ground surface is placed on the floor, a rotor interconnected to the spike member, and a single operator projected above the case. Upon a first depression, a presser of the operator depresses a projection of the rotor downward so that the spike member protrudes from the ground surface. In the protruded state of the spike member, the projection of the rotor is engaged with a receptor formed in a stepped interior of the storage. Upon a second depression, the presser of the operator depresses the projection of the rotor again so as to release the engagement between the projection and the receptor, so that the spike member moves to retract inside the storage of the case.

  • Patent number: 7880075
    Abstract: An angle adjusting structure adapted to a high-hat stand supporting the high-hat cymbals is constituted of a receiving member supporting high-hat cymbals, a first thread attached to the receiving member, a second thread which engages with the first thread and which is revolved to move the first thread up/down so as to adjust a tilting angle of the receiving member, a support member supporting the second thread, and a revolution limiting member limiting the revolution of the second thread. The revolution limiting member includes a plurality of first engagers (e.g. recesses) which are formed on the lower end of the second thread in its circumferential direction and a second engager (e.g. a projection) which is shaped to engage with the first engager and is attached to the support member.

  • Patent number: 7875783
    Abstract: A spring holding mechanism is adapted to a foot pedal including a spring which applies a tensile force to a rotation shaft interconnected with a drum beater of a bass drum. It includes an external thread (i.e. a bolt) interconnected to one end of the spring, a support member having a hole allowing for the external thread running therethrough, and an internal thread (i.e. a fixing nut) that is engaged with the external thread so as to fix the support member in position, thus limiting the vertical movement of the external thread in an axial direction. A projection and a recess are formed in the support member and the internal thread respectively. The projection having an external slope is engaged with the recess having an internal slope so that the projection is received inside the recess when the internal thread is attached to the support member.
