摘要： A turning seesaw which has a fulcrum unit having an upper shaft, an eccentric shaft and a lower shaft on a support. A turning lateral rod is so secured to the upper shaft of the fulcrum as to allow elevational and horizontal turning. At least one upper connecting rod is engaged at one end with a portion of the turning lateral rod intermediate the fulcrum unit and its end, and engaged at the other end with the eccentric shaft of the fulcrum unit. Two pairs of handling rods are pivotally secured to both sides of the turning lateral rod so as to rotate along the axis of the turning lateral rod in a rocking fashion. Two lower connecting rods are each pivotally secured at one end to the lower end of the handling rod and pivotally secured at the other end to the lower shaft of the fulcrum unit, and two seats are mounted at both ends of the turning lateral rod.

摘要： A carousel comprises turntable (10) mounted for rotation about a vertical axis on a frame (12, 13). The turntable (10) carries a plurality, and typically four, see-saw arrangements (11), each of which comprises an arm (43) pivoted centrally to a support (40) and carrying seats (44) at its two ends. Hydraulic rams are arranged to effect movement of the arm (43), as the turntable rotates. The movement of the arms may be linked to the rotation of the turntable. The see-saws may be aesthetically configured to add appeal to young children.

摘要： A multi-use balance beam apparatus is formed by cooperating elements which may be arranged to form a rocker, see-saw, merry-go-round, balance beam, and walking rails. A pair of balance beams, each in the form of a pair of parallel spaced apart rails are constructed to cooperate in a variety of configurations. Additional elements including a locking piece, turning pedestal, and rail retaining guide cooperate with the balance beams to achieve the different functions. The device is useful for child development exercises and a variety of recreational activities.

摘要： A rotatable seesaw device comprises a seesaw lever arm supported by an upstanding supporting structure through a pivotal arrangement in such a manner that rotating motion about the upstanding support structure can be produced as force in peripheral direction is applied and that seesaw motion can be produced by exerting force in vertical direction. The upstanding support structure is detachable and the height thereof can be adjusted to various users such as children or adults. Further, the middle portion of the seesaw lever arm is provided with a plurality of mounting holes spaced along its length and the seesaw lever arm can be supported by the upstanding support structure at selected one of the plurality of mounting holes in order to balance the loading of different weights on opposite ends of the seesaw lever arm, thus the seesaw device can be adapted to be used by persons of different weights. With such arrangement, particularly when force including components in vertical direction and in peripheral direction is applied, rotating motion and seesaw motion can be simultaneously effected to provide a complex, resultant waveform motion around the upstanding support structure, which gives satisfactory thrill and amusement to the users.
