Abstract: A child play structure comprising: a main plate having a max length greater than 58 cm or 80 cm and a max height greater than 58 cm or 80 cm and being arranged at an angle of less than 20 degrees to the vertical, a first side plate having a max length greater than 50 cm and a max height greater than 40 cm and being arranged at an angle of less than 20 degrees to the vertical, wherein said first side plate is fastened to the main plate in such a way that: the first side plate forms a fixed angle to the main plate of between 60 and 90 degrees and at least 30% of the max length of the first side plate extends past each side of the main plate. In this way a play structure is provided which has a very high play value and a very high stability with a low use of materials.

Abstract: The invention relates to a playground equipment comprising a platform for a user to sit or stand on and mounted to the ground via a first shaft and a second shaft. The shafts are connected to each other at an angle and coupled in a gear transmission system. Because of the gearing between the shafts a first rotational speed of the first shaft yields a second rotational speed of the second shaft different from the first rotational speed. The gear transmission system may comprise an epicyclic gear train such as a planetary gear system. The gear transmission system may yield a gear ratio in the range of 1.5-10 such as in the range of 3-7.
