Abstract: In a balance exercise machine (1), a swing mechanism (3) that swings a seat (2) in both of an anteroposterior direction (direction X) and a widthwise direction (direction Y) is rotatably supported on a supporting unit (119 around a predetermined rotation axis (T0). A first inclination mechanism (12) that stands up or down the rotation axis (T0) is provided between the supporting unit (11) and a pedestal (4). A second inclination mechanism (20) that can compensate the posture of the seat (2) is provided between the seat (2) and the swing mechanism (3). By driving the swing mechanism (3), the first inclination mechanism (12) and the second inclination mechanism (20) independently with each other, a stroke of swing motion of the seat can be expanded or contracted. Alternatively, by driving the swing mechanism (3), the first inclination mechanism (12) and the second inclination mechanism (20) in conjunction with each other, the trace of the motion of the seat (2) can be varied.

Abstract: An electromechanical pin setter including a hydraulic drive component. The present invention includes a deck assembly holds pins in deck chutes and reciprocates vertically to spot and re-spot pins on a pin setting location on a bowling lane, a rake mechanism removes pins from the bowling lane, a pit conveyor moves pins and a bowling ball toward a pin elevator, the pin elevator in a pit area lifts pins to a cross conveyor, the cross conveyor delivers pins to a turret, the turret distributes pins to the deck chutes, and a ball elevator to lift the bowling ball to a ball return track. A hydraulic drive component having at least one of a fluid motor and a fluid drive cylinder controls an operation of at least one of the deck assembly, the rake mechanism, the pit conveyor, the pin elevator, the cross conveyor, the turret, and the ball elevator.

Abstract: A distribution indexing device (50, 60) is attachable to bowling pin-setting machines and replaces certain mechanical components within the distributing mechanism (10) that are prone to wear and require constant maintenance. The device (50, 60) includes a drive structure (50) and an electrical contact structure (60). The drive structure (50) is attachable to the distributing mechanism (10) such that a drive gear (54) engages an indexing gear (42). The contact structure (60) includes two contacts (64, 66), one (64) that is attachable to a stationary component (15) of the distributing mechanism (10) and one (66) that is attachable to a moving component (26) of the distributing mechanism (10). As a bowling pin (P) is lowered into a pin magazine (4) by trip arms (22), the arms (22) cause the movable contact (66) to engage the stationary contact (64), thus generating an electrical signal to the drive structure (50).
