Easily Installed Folded Trampoline

Abstract

This invention refers to a folded trampoline which can be installed easily. It is equipped with tubes aimed at supporting bed surface as well as feet outside the bottom of the tubes. There are folding devices between the tubes and the feet, which consist of exterior folding units, interior folding units, handle, plug pin and reset spring. The exterior folding units which are furnished with locating holes, plus the interior folding units, are connected with tubes, and the feet linked with the inner side of the exterior folding units are articulated with the interior folding units and armed with through-holes which plug pin can go through. This invention has several elastic cords corresponding to fixed units. During installation, one end of the elastic cord will be inserted into the fixed unit, and the other end will go through the ring and the tube successively. After passing through all the rings of elastic cord between two legs, the other end shall be inserted into the fixed unit of the first neighboring elastic cord to assure quick installation.
