Abstract: To stimulate and engage children, especially older children, playground equipment is disclosed which provides a suitable challenge, by consisting of three columns which are arranged in a triangular cross-sectional form which tapers inwardly. The columns are assembled with connection tubes at the top and possibly also further down to provide a stable and very strong construction which supports various accessories elements such as ropes, climbing walls, cross-beams, etc. A spherical assembly bracket with through holes is mounted on a column and used in the assembly and suspension of the accessory elements.

Abstract: A recreational appliance with springs (1) is provided with a locking element (2-9) which can be inserted in an anchoring element with a receiving flange (4), whereby a recreational appliance can be locked to the fundament in such a manner that it can be removed after it has been unlocked. The lock is preferably configured to have two lock plates (5) which engage bolt retaining edges (15) in the flange (4), which is provided with a recess (14) in which the locking element (2-9) is inserted. A recreational appliance can then function in the same way as an ordinary permanently ground anchored appliance, but the locking element makes it possible to remove the appliance after it has been unlocked, for area maintenance or repairs, or to avoid damage to the recreational appliance.
