The present invention also provides a trampoline wherein the top panel and the main body are formed as a single piece. The present invention further provides a method of manufacturing trampoline wherein the top panel is attached to the mail body by RF welding or heat sealing, or the top panel and the mail body are formed as a single piece.

Abstract: A fall protection system is provided providing all protection for all workers in building erection. The system involves an interior net, and a perimeter net if needed. The net system may be both horizontally and vertically mobile, allowing it to be easily moved as building erection continues.

Abstract: This is the embodiment of the net apparatus used in sports and in the non-sports arenas. This net's frame supports an inner net framed matrix that connects and pivots a rear frame for an adjustable triangular-shaped lean to control the trajectory of the ball or object. The net is designed to rebound balls or objects with high energy even at side angles to return the ball to the sender. The net is also designed to minimize stress to both net and frame when a ball or object contacts the net.

Abstract: A safety apparatus configured for attachment to a manlift and configured to prevent objects falling over the side of the manlift from striking objects and people beneath the manlift. One embodiment includes a frame configured to support netting that is disposed on the platform of an open-sided manlift and angled outward to intercept objects falling vertically outside the surface area of the platform. Another embodiment includes a frame that extends beyond the lip of a dosed-sided manlift and contains netting configured to catch objects falling outside of the surface area of the closed-sided manlift.

Abstract: The present disclosure relates to a perimetric protection system for buildings undergoing construction including at least two masts (1) spaced from one another and each formed by two vertical U-profiles (1); a horizontal platform (3) supported on at least two horizontal beams (300) attached to the masts by means of first attachment elements or anchors (130). The system further comprises: at least two inclined beams (100) parallel to one another, which are attached: to the masts (1) by means of at least two second attachment elements (110) forming a first angle (?); to the horizontal beams (300) by means of at least two third attachment elements (310) forming a second angle (?); and, the at least two inclined beams (100) having a free end (100a) in the third attachment elements (310), such that their height is greater than the height of the horizontal platform (2); an inclined protective panel (120) attached to said at least two inclined beams (100).

Abstract: A flexible member used as a rope in a mesh has an outer sheathing which is easy to touch and an inner core which is shrinkable so that when used in a mesh which is suspended on a frame, it pulls the frame tautly by the shrinkage of the inner cords. Also, a connection between a support member and a border can be effected using one way mechanical fasteners. Shrink nets can be further used on a frame without sheathing with a twisted cord.

Abstract: A free standing perimeter net system is disclosed. The perimeter net system is comprised of a support arm, a support cable, an uplift brace, at least one net system brace, a back plate, a pivot, a vertical support, a strut, and a pair of strut brackets. These components work together to allow a safety net system to easily be installed around a structure without directly attaching to the structure. The support arm rotates between an open and a closed position on the pivot. This configuration allows the net, which is attached to the support arm, to be deployed at various angles. When the support arm rotates, the uplift brace also adjusts and aids in securing the support arm and net in the desired position. The vertical support couples the net system to the building or structure via the back plate and strut. The net system braces are also attached to the vertical support and provide added rigidity to the net system.

Abstract: A fire escape device including a collapsible frame from which is suspended a large receptacle, preferably of net material, and support means for the frame to support the frame and receptacle in a collapsed position within the interior of a building, and permitting protraction of the frame and receptacle to an extended and open position outside the exterior wall of the building for receiving persons falling from an opening, such as a window, vertically above the receptacle.

Abstract: Rescue apparatus is described for use in the rescue of persons from high rise and other buildings, which includes a net of flexible material carried by a frame that extends outwardly from a window below the location of the person to be rescued, with portions engaged with the floor and ceiling of the room which apparatus is extensible, collapsible, foldable, and portable to provide easy assembly for use.The apparatus includes cushioning members on the frame carrying the net and a scoop inside the net to direct the rescued person inside the window.

Abstract: An elongated, normally horizontally disposed, generally rectangular base frame supported adjacent to its opposite ends by pairs of legs, and a pair of end frames each having a pair of spaced parallel posts connected adjacent one end by a cross-member and pivotally connected at their other ends to the legs at one end of the base frame for movements between operative generally vertical positions and folded generally horizontal positions overlying the base frame. An elongated top frame is detachably mounted to the end frames adjacent the cross members and, like the base frame, is provided with a body supporting sheet. An intermediate frame, similar to the top frame, is detachably mounted between the end frames, and top and intermediate frames being adapted to be horizontally disposed and held in stacked relationship between the base frame and the end frames in their folded positions.

Abstract: A catching device for a free-falling body comprising a material web which is held at opposite sides at support bars or ledges which are supported at a spacing from the floor. The support bars are held resiliently damped at a portable base frame carrying tensioning devices for stretching or tensioning the material web.
