Abstract: This disclosure relates to tiltable trampoline frame support structures that include a front support member, a rear support member, two elongated link members and two elongated adjusting link members. The front support member and the rear support member are pivotally coupled to frame members and are pivotal about a horizontal axis perpendicular to the front line of the trampoline. The horizontal link members are pivotally coupled between the front support member and the rear support member. The upper ends of the adjusting link members are pivotally coupled to the upper ends of the front support member and the lower ends of the adjusting link members are movable coupled to the horizontal link members in a such way that the tilt angle of the rebounding mat shifts when the coupling place of the adjusting link members to the horizontal link member is adjusted.

Abstract: In this disclosure a connection arrangement for a trampoline is set out, the arrangement including a mat and a frame. The connection arrangement includes a cord and a security piece, which includes a receiving part and a cord holding part. The cord holding part is configured to receive both ends of the cord and thus forming a loop that includes the cord and the cord holding part. The receiving part receives the cord holding part and one end of the loop through an opening. The loop is configured to wrap around some horizontal part of the frame of the trampoline when the connection arrangement is fitted onto the frame.

Abstract: A trampoline frame structure that comprises multiple transverse pipes, joint sleeve structures and leg arrangements is disclosed. The joint sleeve structures serve to connect transverse pipes to form a rim structure. Leg arrangements are connected to the joint sleeve structures. At the upper end of the joint sleeve structure is an elongated headpiece, and at both of the ends of the headpiece are sockets. The cross-section of the socket is polygonal. At the ends of the transverse pipes are conical connection extensions, and the cross-sections of the extensions correspond to the cross-sections of the sockets. The assembled rim structure comprises the transverse pipes with the headpieces between them.
