## Background
BACKGROUND
Large, multi-user trampolines have been adapted or entertainment and exercise purposes in the past. However, many of the designs for such systems have a number of limitations. These include complicated construction and positioning of cables and other coving components where they can wear against one another. Accordingly, there is a need for a multi-user trampoline configured to reduce wear, and provide simplified, modular design and construction to fit a pre constructed space.

DETAILED DESCRIPTION
A multi-user, multi-zone trampoline is disclosed. Referring to FIG. 1, the trampoline 10 includes a jump surface 12 at least partially enclosed about a perimeter by side panels 14 and 16. Jump surface 12 comprises multiple smaller, planar segments 18. Each segment 18 comprises a resilient fabric suitable to use in trampolines and is attached by springs to cables running under pads 20. The cables and segments 18 may be arranged in a grid-like fashion. An opening 22, is provided to allow users entry onto jump surface 12. Opening 22 is shown in a corner, but could be positioned elsewhere as well.
Jump surface 12 and side panels 14 and 16 are supported by frame 24. Frame 24 includes a variety of generally straight members coupled together. First vertical members 26 are positioned to support first horizontal members 28 about a perimeter of jump surface 12. In some embodiments, angled members 30 may be used to partially define the perimeter about jump surface 12. The segments 18 along the outside of jump surface 12 may generally be attached along one side to one or more of first horizontal members 28.
Second vertical members 32 extend from the floor to a height above jump surface 12. Second vertical members 32 are positioned to support second horizontal members 34 and angled members 36 to provide a second perimeter. The second perimeter is positioned above jump surface 12 and extends outside the perimeter of jump surface 12. The allows for the mounting of side panels 14 and 16 such that they extend at an angle
Baseplates 38 and 40 may be used to secure vertical members 26 and 32 to a floor, respectively. Various configurations of bracing members such as bracing member 42 may be used to provide a rigid frame.
Referring to FIG. 2, second vertical member 32 is shown in greater detail. Second vertical member 32 includes a main body 44 shown as a hollow rectangular tube. In other embodiments, main body 44 could be solid or of a different cross-section. Main body 44 extends vertically from a baseplate 38 to a top plate 46. Baseplate includes a plurality of apertures for anchoring into a floor. Plate 48 is provided at baseplate 38 and may be coupled to both baseplate 38 and main body 44 by welding or other appropriate means. An aperture is provided in plate 38 may be provided for anchoring one or more of the cables used to suspend jump surface 12 show in FIG. 1. Top plate 46 may be provided with apertures to facilitate fastening to horizontal members 34 and/or 36.
Referring to FIG. 3, first vertical member 26 includes main body 52 that extends from baseplate 40 to cap 50. Cap 50 is configured to allow the passage of two perpendicular steel cables, one above the other. In more detail, as shown in FIGS. 4 and 5, cap 50 includes a top cable guide 54 and a bottom cable guide 56. These components may be identical for ease of manufacture. Top cable guide 54 includes projections 58 which partially define a channel of suitable width to accommodate a cable of desired thickness. Similarly, bottom cable guide 56 includes projections 60 which partially define a channel configured to accommodate a cable of desired thickness running perpendicular to the channel partially defined by projections 58. Additionally, apertures 62 may be provided in top cable guide 54 in positions roughly corresponding to the top surfaces of projections 60 from bottom cable guide 56. These apertures may provide welding points for permanently coupling top cable guide 54 to bottom cable guide 56 to form cap 50. Alternatively, apertures 62 may allow for staking, fastening or other coupling means. As shown most clearly in FIG. 5, edges of the cable guides 54 and 56 may extend beyond one another to provide welding contacts for coupling cap 50 to main body 52. Cable guides 54 and 56 are shown as curved to allow for the guided cable to be directed downward towards an anchor point, such as the aperture in plate 38 of second vertical member 32.
The various horizontal members may be of a configuration general like that shown in FIG. 6. As with the other frame members, horizontal member 28 may include a main body 64 constructed of hollow rectangular tubing. End plates 66 may be provided for coupling horizontal member 28 to one or more vertical members, or to another horizontal member. Apertures 68 are provided for coupling springs for supporting segments 18 along one side. End plates 66 may include a flange portion 70 extending beyond the cross-sectional perimeter of main body 64. Apertures may be provided in flange portion 70 to facilitate fastening horizontal member 28 to a vertical member or another horizontal member. Alternatively, horizontal member 26 may be anchored to a vertical surface in certain embodiments.
FIGS. 7 and 8 show a constructed multi-layer trampoline. In these images, a first lower jump surface 54 is positioned below a second jump surface 12. Both jump surfaces are divided into segments. The lower surface 54 is framed by a grid of lower horizontal members 62 which are attached to the vertical members 52 via side apertures 64. As further shown, the lower level horizontal members 62 further include openings to link with a number of springs 56 which support the lower jump surface 54. Preferably, the vertical members 52 extend from baseplates anchored to the floor at each intersection and the upper horizontal members 67 and the lower horizontal members 62 are coupled thereto.
As further shown in FIGS. 7 and 8, the second jump surface 12 includes segments coupled to a grid of steel cables 58. The intersection of two perpendicular cables corresponds to a cap of a vertical member 52. This prevents rubbing of cables against one another when the trampoline is in use. Springs are used to couple the segments to the steel cables along the segment edges, and to couple the segment corners to the vertical members. Along the outermost perimeter of the second jump surface 12, springs 60 may be used to couple the segments to horizontal members. The multiple layers allow a user to gain greater height by deflecting the top layer to a point that the top layer comes into contact with the lower layer. The physical properties of the material used in the two layers may be different, such as, for example, the lower layer may be less deformable. In such cases a lesser displacement of the lower lay would correspond to a higher amount of stored energy than for the upper layer.
