Playground equipment comprising a revolving ring for standing or sitting on is according to the invention composed of ring segments (1) which are connected by means of connecting pieces (2) for forming a closed ring. The revolving ring is mounted somewhat above the base by means of legs (3) and by adapting the length of the legs, an inclined revolving plane may be obtained. The structure itself comprises a stationary ring (5, 6) on which a revolving ring (4) provided with wheels or rolls (9, 10) may roll. The revolving ring (1) fits tightly about the stationary part of the playground equipment and it is not possible to separate the parts apart once the playground equipment has been assembled and held together by means of locking rings (12).

DETAILED DESCRIPTION What is claimed is: 1.
Playground equipment comprising: a stationary circular ring mounted on supporting legs; a revolvable circular ring revolvably mounted on the stationary circular ring; at least one first wheel rotatable about a horizontal axis and at least one second wheel rotatable about a vertical axis, the first and second wheels disposed between the stationary circular ring and the revolvable circular ring to provide rolling engagement therebetween.
2.
Playground equipment according to claim 1 wherein the supporting legs have different heights for inclining the stationary circular ring and the revolvable circular ring mounted thereto.
3.
Playground equipment according to claim 1 wherein the revolvable circular ring has a deck on an upper side thereof.
4.
Playground equipment according to claim 1 wherein the stationary circular ring has a horizontally extending flange and a vertically extending flange, the support legs secured to the horizontally extending flange.
5.
Playground equipment according to claim 1 wherein the revolvable circular ring is a horizontally extending ring.
6.
Playground equipment according to claim 1 further comprising at least one wheel support mounted to an underside of the revolvable circular ring for supporting the at least one first wheel and the at least one second wheel.
7.
Playground equipment according to claim 4 wherein the at least one first wheel is in rolling engagement with the horizontally extending flange of the stationary ring and the at least one second wheel is in rolling engagement with the vertically extending flange of the stationary ring.
8.
Playground equipment according to claim 3 wherein the deck comprises an assembly of ring segments, connecting pieces connecting the ring segments together.
9.
Playground equipment according to claim 8 wherein each connecting piece surrounds a pair of mating ends of the ring segments.
10.
Playground equipment according to claim 9 further comprising locking rings for securing each connecting piece to the mated ends of the ring segments
