摘要： A fallboard arrangement for a keyboard instrument, which makes it possible to make flat the entire upper surface of a keyboard instrument in a closed state. A fallboard back section is immovably provided in a rear part of the body, in a horizontal state. A fallboard is movable between a closed position where it is forward of the fallboard back section and has an upper surface thereof made flush with that of the fallboard back section in a state closing the performance section and an open position where it is upward of the fallboard back section so as to open the performance section. A hinge connects the fallboard to the fallboard back section in a manner pivotally movable between the closed position and the open position and is disposed downward of the fallboard in the closed position and the upper surface of the fallboard back section.

摘要： A mechanism for supporting the weight of a piano lid is disclosed. One or more pneumatic cylinders and arms are used to assist a user in opening and closing the piano lid. In one embodiment, a guiding cup can be removably attached to the frame of the piano below each pneumatic cylinder. When the piano lid is open, the piston arm of the pneumatic cylinder engages the guiding cup. Because the pneumatic cylinder is not attached to the piano frame, the piano lid can be completely removed without the use of tools. Another embodiment provides a mounting bracket that fits over the rear frame of a piano, allowing the mechanism to be retrofit to any existing piano without any damage thereto.

摘要： A fallboard structure of a keyboard instrument capable of selectively shielding or opening the inside of the instrument from or toward a player. A fallboard covers a keyboard section when it is closed, and permits the keyboard section to be operated for performance when it is open. A front plate pivotally supports the fallboard and shields a space upward and rearward of the keyboard section against a player when it is in a first state. When the fallboard is made open and engaging portions of the front plate are moved along displacement guides provided at supporting portions disposed at side portions of a keybed, the front plate is moved in unison with the fallboard and changed to a second state where the space upward and rearward of the keyboard section is open toward the player.

摘要： A self-locking keyboard bracket is disclosed to include a four-bar linkage, formed of a base frame, a connecting frame, a coupling frame, and a braking mechanism, a supporting frame fastened pivotally with the coupling frame, and an angle adjustment control unit for locking the supporting frame to the coupling frame at the desired angle by means of the operation of a locking bar with a cam. The braking mechanism uses a beveled block to mach with a beveled guide block to further control friction resistance between the base frame and the connecting frame, thereby achieving self-locking of the keyboard bracket.

摘要： A fall board structure is provided for a keyboard instrument having a keyboard, in which a plurality of keys are arranged between side arms, to actualize light, comfortable and safe operations of a fall board. The fall board structure is basically constructed by arms, torque shaft units and rotation members. Herein, the arm is fixed to a side end of the fall board, so that it rotates in response to rotary movement of the fall board, while the torque shaft unit is fixed to the side arm of the keyboard, wherein it has a shaft portion which rotates in accordance with the rotary movement of the fall board. The rotation member is constructed by a clutch portion and a in lever portion, which is brought into contact with a lower edge portion of the arm at a contact point. The shaft portion of the torque shaft unit engages with the clutch portion of the rotation member equipped with a one-way clutch mechanism such that the clutch portion locks the shaft portion when the shaft portion rotates in a counterclockwise direction corresponding to a close operation direction of the fall board while the clutch portion releases the shaft portion when the shaft portion rotates in a clockwise direction corresponding to an open operation direction of the fall board. Thus, only in a close operation mode of the fall board, the torque shaft unit produces resistance force, which is transmitted to the arm via the contact point.
摘要翻译：提供了一种用于具有键盘的键盘乐器的倒板结构，其中多个键布置在侧臂之间，以实现坠落板的光线，舒适和安全的操作。坠落板结构基本上由臂，扭矩轴单元和旋转构件构成。这里，臂固定在坠落板的侧端，使其随着坠落板的旋转运动而旋转，同时扭矩轴单元被固定在键盘的侧臂上，其中它具有轴部分其根据坠落板的旋转运动而旋转。旋转构件由离合器部分和杠杆部分构成，其在接触点处与臂的下边缘部分接触。扭矩轴单元的轴部与具有单向离合器机构的旋转构件的离合器部接合，使得离合器部分在轴部沿对应于闭合操作方向的逆时针方向旋转时锁定轴部当所述轴部沿对应于所述坠落板的打开操作方向的顺时针方向旋转时，所述离合器部分释放所述轴部。因此，仅在坠落板的关闭操作模式下，扭矩轴单元产生通过接触点传递到臂的阻力。
