<p>Disclosed is a swing in which the seat is tilted back and forth while being sat upon so as to allow the swing to describe a reciprocating motion as the seat is moved in a seated posture by means of a kinematic design. The swing of the present invention, in which the seat is tilted back and forth while being sat upon, comprises: a rotational shaft rotatably connected across the upper parts of frames which are separated from each other; vertical bars extending downwards from both sides of the rotational shaft; a seat rotatably attached to the lower ends of the vertical bars; attachment plates which extend further downwards from the bottom sides of central parts on both sides of the seat, and, on the bottom ends of which, the vertical bars are coupled in hinged fashion; and a rear stopper and a front stopper formed projecting outwards on both sides of the seat, such that the seat flip flops while coming into engagement with the vertical rods. Here, a plurality of insertion holes are also formed in the seat behind the rear stopper, such that the rear stopper can be attached to and detached from the insertion holes.</p> |
