  • Patent number: 11090570
    Abstract: The invention provides a swing for playing in standing posture which comprises a step plate defined with two long sides and two short sides, and two suspension components. The suspension components are disposed on the long sides respectively. Each suspension component includes two slings disposed at one of the long sides, and a handle assembled with the two slings and parallel to the long sides. The handle comprises two through holes for the two slings to pass through, and the two slings do not wound around the handle at any part thereof. Each sling comprises a stop sleeve and a knot. The stop sleeve moves along the sling if a force bore by the stop sleeve is greater than the friction between the stop sleeve and a surface of the sling. A position of the handle on the sling is defined by the stop sleeve and the knot.

  • Patent number: 10166422
    Abstract: A trampoline support frame comprises transversal and longitudinal branch pipes. The transversal ones are connected to form an annular frame. Each longitudinal one is provided with a fitting portion and two reinforcing portions integrally extended from the fitting portion to corresponding two side surfaces of the transversal one and then fixed to the transversal one by welding. The two reinforcing portions of each longitudinal one are extended from and integrally formed with the fitting portion, such that each transversal one is fixed to the two reinforcing portions by welding directly after the transversal one is placed between the two reinforcing portions without precision alignment, whereby the manufacturing process for the trampoline support frame is simplified, and manufacturing energy consumption is reduced to meet requirements for environment protection.

  • Patent number: 9689519
    Abstract: A trampoline support structure includes a manifold, a first annular tube, a mesh encircled tube, a second annular tube and a support tube. The manifold includes a longitudinal installation portion, a transverse installation portion and an installation hole located on the transverse installation portion. The first annular tube includes a first assembly section inserted into the transverse installation portion and an anchor hole located on the first assembly section. The mesh encircled tube includes an anchor section inserted into the installation hole, the anchor hole and the longitudinal installation portion. The second annular tube includes a second assembly section inserted into the first assembly section. The anchor section, the longitudinal installation portion and the support tube form a multi-layer structure, thus can solve the problem of inadequate structural strength occurred to the conventional techniques.
