In a spring device (2), in particular for coil spring supported playground appliances, comprising a sturdy coil spring (4) which is adapted at one end for anchoring to the ground and which is adapted at the opposite end to be connected to a playground appliance, and means arranged to limit the movements of the coil spring, the means for limiting the movements of the coil spring comprise at least one connection member (8) whose opposite ends are connected, preferably within the hollow of the coil spring, to fitting parts (6) to which opposite end parts of the coil spring (4) are intended to be connected, the connection member (8) being predominantly bend resistant at right angles to the axis of the coil spring along a mainly vertical transverse plane of the spring device (2). By these means a possibility of preventing sideways swinging movements of the coil spring is attained in a simple way, provided, of course, that the spring device as a whole is mounted correctly, that is, such that the bend resistance of the connection member acts in transverse to the forwardbackward movements of the playground appliance. |
