  • Patent number: 8832874
    Abstract: A person moving device for moving a person of limited mobility. The device comprises a lower floor engaging frame part (1) and an upper patient carrying part (6) adapted to carry a patient by engaging the patient's torso from the front and which is mounted to the lower frame part for movement between a patient load-unload position and a patient transport position. The upper patient carrying part being mounted to the lower frame part for curvilinear movement about an axis extending across the patient and positioned so that the patient's torso moves substantially by rolling about an axis across the device and the patient and substantially about a center of mass of the patient. A handle (12) is also provided by which a user can cause the upper patient carrying 10 part to move from the load-unload position to the transport position.

  • Patent number: 8303469
    Abstract: A trampoline comprises a flexible mat, a plurality of resiliently flexible rods each having an upper end retained in the flexible mat, and a base frame arranged to retain the lower ends of the flexible rods. The base frame comprises for each rod an aperture through an upper side of the base frame into the interior of the tubular frame, and a formation into the interior of the tubular base frame from the lower side of the base frame and spaced laterally from the aperture, which may be formed by deforming material of the underside wall of the base frame into the interior of the base frame, for receiving the lower end of the flexible rod.

  • Patent number: 7854687
    Abstract: A trampoline comprising a flexible mat (3) and a plurality of springs (4) holding the mat in tension within a peripheral frame (1) of the trampoline which surrounds the mat has an enclosure system surrounding the mat. The enclosure has a lower peripheral part coupled to the mat and a plurality of resiliently flexible upright enclosure members (5) to support the barrier above the mat. The enclosure support members are free to resiliently deform away from the mat when impacted by a user against the barrier. They are also connected together at the upper ends of the enclosure support members away from their natural rest state and towards the center of the mat. When impacted by a user against the barrier on the side of the enclosure causing the barrier to resiliently deform away from the mat, the enclosure support members are resiliently deformed towards the center of the mat.

  • Patent number: 7708667
    Abstract: A trampoline has an enclosure system including a barrier of a flexible material (14) such as a net material surrounding the trampoline mat above the mat and having a lower peripheral part coupled directly or indirectly to the mat, and a plurality of resiliently flexible generally upright enclosure support members or rods (13) which are retained at or towards the lower ends of the enclosure support members and below the mat (1) by the frame (4) of the trampoline and which support the net above the mat, so that the enclosure is free to deform away from the mat when impacted by a user against an enclosure support member and/or against said barrier of flexible material.
