Abstract
A swinging playground device includes a swing platform. The swinging playground device also includes a skirt coupled to the swinging platform and fills an area below the swinging platform as the swinging platform moves in a swinging motion.
Claims20
A playground device, comprising:
- a platform;
- an acceleration assembly operatively coupled to the platform, the acceleration assembly including:
- a plurality of linkages pivotally connected to each other, and wherein at least one of the linkages is also pivotally connected to the platform;
- a coupler attached to the platform;
- and
- a force storing component that forms at least part of a connection between the coupler and the plurality of linkages, wherein the force storing component stores potential energy when the platform is in a resting position and releases the stored potential energy to assist in initiating motion of the platform.
3 more elements
A method of operating a playground device, the method comprising:
- providing a platform;
- providing an acceleration assembly that includes a plurality of linkages pivotally connected to each other, and wherein at least one of the linkages is also pivotally connected to the platform;
- changing an angle between the first and second linkages as stored potential energy is released from a force storing component that is connected to the plurality of linkages, and
- wherein said change in the angle is proportional to a change in the force storing component.
1 more element
An acceleration assembly for a playground device, comprising:
- a plurality of linkages pivotally interconnected, wherein at least one of the linkages is also pivotally connected to a platform of the playground device;
- a coupler attached to the platform of the playground device;
- and
- a force storing component forming at least part of a connection between the coupler and the plurality of linkages, wherein the force storing component is configured to store potential energy when the platform is in a resting position and to release the stored potential energy to assist in initiating motion of the platform.
