Abstract

In order to make it easier to mount for instance playground equipment comprising a tube construction which is anchored to a base the subject invention offers a simplification by incorporating a means to facilitate the longitudinal adjustment of the grooves in relation to the base. This means comprises a tube piece (2) extending in the tube (1), which tube piece is anchored to the base and which is configured with longitudinal folds for the formation of outwardly open channels (4). In these channels (4) a wedge element (3) is inserted which by means of bolts (6) through the tube (1) can tighten the wedge and due to the cross sectional shape of the grooves cause the tube piece (2) to expand so that it squeezes against the inside of the tube (1). In this manner the tube (1) can be adjusted in the longitudinal direction in connection with both the mounting and the subsequent adjustment.

Description

THE KNOWN PRIOR ART

[0001] The invention relates to a means of mounting and adjusting two tubes which can slide inside one another.

[0002] When constructing playground equipment comprising a frame of metal rods or tubes, each metal tube is normally secured to a base in order to provide a stable and safe item of playground equipment.

[0003] U.S. Pat. No. 6,095,950 discloses an example of such an item of equipment comprising three posts which at their bottom are provided with feet being secured to the base.

[0004] This construction does not permit immediate adjusting or setting and therefore requires a carefully erected base. Add to this that problems may occur in the event that the foundation subsides or the posts deform which will require the adjusting of one or more of the posts at the base. Any such adjustment will have to be performed by adjusting the actual attachment to the base.OBJECT OF THE INVENTION

[0005] It is the object of the invention to facilitate the installation of the pl...
