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.
Claims15
A playground equipment comprising a platform for a user to sit or stand on, wherein the platform is mounted to the ground via a first shaft and a second shaft, which are connected to each other at an angle, wherein the platform is configured to rotate with the first shaft around a first rotational axis aligned with the rotational axis of the first shaft, wherein the playground equipment is configured to rotate around a second rotational axis aligned with the rotational axis of the second shaft, and wherein the first and second shafts are coupled in a gear transmission system with a gear ratio that is different from one another such that a first rotational speed of the first shaft yields a second rotational speed of the second shaft, which is different from the first rotational speed of the first shaft such that the platform is configured to rotate with the first shaft around the first rotational axis at the first rotational speed while the playground equipment rotates around the second rotational axis at the second rational speed.
