<p>The present invention relates to a simple and easily assembled three-dimensional frame. Essentially, this consists of joint pieces that have connector means that themselves consist of bodies that can be connected to each other and are separable, the casings of which are more or less cylindrical or polyhedral. In addition, the three-dimensional frame has tubular or rod-type connector pieces that can be joined to the connector means of the joint pieces that are arranged at intervals from each other, for example by means of screw connections. The joint pieces consists of circular, concentrically arranged bodies. Each body defines a plane of connection with an equal number of connectors.</p> |
