The tandem pulley comprises a pair of sheaves mounted in line between first and second flanges. A gate is fitted rotating with respect to the first flange between closed and open positions. The gate comes into contact with the second flange in the closed position to close a housing. The clamp is movable in rotation on the gate between a locking position locking the gate in the closed position and an unlocking position. The clamp has a prong pressing on the first flange and the gate in the locking position. The clamp has an actuating area separated from the first flange by the gate. Rotation of the actuating area from the locking position to the unlocking position corresponds to a movement of the actuating area away from the second flange. Rotation of the actuating area results in pivoting of the prong.

The disclosure of the present invention relates to a play experience system and a physical development status acquisition method using the same, which can precisely measure physical development items of users including children and juveniles by using play-type experience devices, and can acquire experience data based physical development status by analyzing a correlation between an experience instrument itself and the physical development item.

A pulley block is disclosed. The pulley block comprises: first and second plates and a pulley sheave disposed between the plates for rotation on bearings upon a sheave axle that extends between the plates along a sheave axis. The plates are connected to the sheave axle so as to permit rotation of one plate with respect to the other about the sheave axis between a closed position of the pulley block and an open position of the pulley block. Each plate has, at a position remote from the sheave axis, a respective bollard formation, which bollard formations are disposed such that, when the plates are in the closed position, the respective bollard formations are in contact with or in close proximity to one another to form a bollard that extends between the plates. When the plates are in the open position, the respective bollard formations are spaced apart. The pulley sheave rotates on bearings upon a sheave axle assembly that extends between the plates along a sheave axis. Which assembly has a main axle that is fixed for rotation with respect to the first plate and free for rotation with respect to the second plate and an axle cap that clamps the main axle to the first plate, the axle cap being removably secured to the main axle.

A play experience system disclosed in the present invention comprises an experience device including a plurality of experience rooms and a plurality of experience instruments provided in each of the plurality of experience rooms for the user to experience the play-type; a sensor device comprising at least one or more sensors being disposed in a predetermined area of each of the plurality of experience instruments; and a processing device configured to receive body composition information and heart rate information of the user and comprehensive measurement information on physical development items of the user from the at least one or more sensors, and to obtain result information on a current level of the physical development items of the user by comparing the received comprehensive measurement information on the physical development items with pre-stored standard information on the physical development items.

A bogie configured to move along a track of an amusement ride includes two first lateral wheels, on each side of a vertical center plane of the bogie, for rolling along a run of the track. A second lateral wheel is mounted on each side of the vertical center plane and is movable perpendicular to the vertical center plane between a first position proximate the vertical plane and a second position spaced-away from the vertical plane. The bogie also includes a mechanism that provides a force to normally bias the second wheel toward the first position. The mechanism is configured such that the magnitude of the provided force increases with increasing separation between the second lateral wheel on one side of the vertical center plane and the second lateral wheel on the other side of the vertical center plane.

An automated damping system including a damping device arranged and disposed to provide variable resistance to a load. The variable resistance provides resistance values corresponding to a displacement position of the damping device. The system includes a damping profile generator that calculates a damping profile and a sensor is arranged and disposed to measure one or more damping affecting properties. The sensor provides the one or more damping affecting properties to the damping profile generator. The damping profile provides the variable resistance based upon the one or more damping affecting properties of the load.
