Patent number: 8832874Abstract: 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.Type: GrantFiled: June 29, 2010Date of Patent: September 16, 2014Inventor: Keith Vivian Alexander

Patent number: 7854687Abstract: 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.Type: GrantFiled: December 9, 2004Date of Patent: December 21, 2010Assignee: Board & Batten Inc.Inventor: Keith Vivian Alexander
