Abstract
Play apparatus comprising at least three beam members which are pivotally mounted a relatively short distance above the ground with adjacent end portions being interconnected by a resilient sleeve so that movement of any one of the beam members causes a corresponding movement of the other beam members. Each beam member is pivotally supported between its ends by a pivot mount.

Playground apparatus comprising:
- at least three separate elongated beam members extending in generally horizontally spaced end to end parallel aligned relationship and having opposite end portions of adjacent ones of said beam members located next adjacent one another;
- a single pivotal support means including a shaft means and a bearing means associated with each of said beam members for pivotally supporting each of said beam members at an intermediate location between said opposite end portions whereby each of said beam members are pivotally supported in vertically spaced relationship above the ground for up and down see-saw type pivotal movement of said opposite end portions of said beam members;
- and
- resilient flexible connecting means extending between adjacent ones of said opposite end portions of adjacent ones of said beam members for causing simultaneous up and down see-saw type movement of adjacent ones of said opposite end portions.
