Abstract: A joint structure for connecting two hollow frame tubes in sporting equipment. The tubes have a shell, a sleeve part, and a receiving part. The sleeve part is configured to fit into the receiving part in such a way that there is a hole running through both parts. The joint structure includes a locking arrangement having an elongated spring strip that is bent into a first wing and a second wing. The holding part includes a first connecting element and a second connecting element. The first connecting element is configured to be inserted inside of the sleeve part and the second connecting element is configured to be fixed to the first connecting element in such a way that the shell of the second tube and the shell of the first tube is between the connecting elements.

Abstract: A basketball hoop structure is described herein. The basketball hoop structure includes a frame, a rim, a backboard and a fixing arrangement having an elongated trough. The hoop structure may be fixed onto a support tube of a trampoline. The support tube includes two slits and a locking hole. The trough includes two locking plates and a locking pin. When the basketball hoop structure is fixed to the support tube, the locking plates are inside the slits of the support tube and the locking pin is inside the locking hole.

Abstract: A basketball hoop structure configured to be fixed onto a trampoline is disclosed. The basketball hoop structure includes a frame, a rim and a backboard. The rim has a horizontal position, is connected to the frame, and pivots vertically from the horizontal position. The rim includes a connection arrangement having a first branch and a second branch for connecting the rim to the frame. The basketball hoop structure further includes a first elastic arrangement and a second elastic arrangement. Parts of the first branch and the second branch are positioned between the elastic arrangements. The elastic arrangements dampen the movements of the rim and return it to the original position.
