Definitions
- the invention relates to improvements to a trampoline for sporting and/or recreational use which is soft-edged relative to conventional trampolines which support the mat of the trampoline via a solid peripheral frame and exposed springs between the frame and the mat.
- the rod stiffness against bending in the range 600-900 N/m, and most preferably is about 700 N/m.
- the rod deflection is in the range 150 to 250 mm and most preferably about 220mm.
- Trampolines of the invention may be circular, square, rectangular, or of other shapes such as octagonally shaped in plan view for example.
- Figure 2 is a side view of the trampoline of Figure 1
- Figure 3 is similar to Figure 1 but of one side of the trampoline only and showing a portion of the edge of the mat of the trampoline cut away, and
- Figure 3 a is an enlarged view of the cut away edge portion of the trampoline
- Figure 4 shows the rod deflection measurement at the trampoline edge
- Figure 5 shows the range of rod stiffnesses and rod deflections that achieve the edge and mat properties required in accordance with the invention
- Figure 6 illustrates the cantilever rod notation for the equations given subsequently
- a preferred form trampoline comprises a flexible mat 1 on which users may bounce, a plurality of resiliently flexible rods 2, and a base frame 3.
- the preferred form trampoline shown is circular in shape but the trampoline could be of any other desired shape such as oval, square, rectangular or similar.
- the base frame of the preferred form trampoline comprises a circular beam 4 typically formed of steel or aluminium for example, which may be supported from the ground by legs 5.
- a number of the fittings 6 are positioned within this pocket in the peripheral edge of the mat as shown in Figures 3 and 3a in particular.
- the fittings may be loosely captured within the pocket or alternatively may be stitched to the mat within the edge pocket, or mechanically fastened to the mat via rivets for example.
- the rods in the preferred form each have a ball-shaped upper end 12 which connects to a socket cavity in the underside of one of the fittings 6.
- the fittings 6 will be formed from a plastics material, by injection moulding for example.
- the fittings may optionally include a slight dome on the body of the fitting over the socket cavity, on the underside of the fitting.
- the fittings have an outer edge which in use is closest to the outer peripheral edge of the mat, which edge is wider in the planar than in the inner edge of fittings, so that the fittings have an approximate truncated triangular shape and plan view, with concave sides, but this is non-limiting and in other forms the fitting could be alternatively shaped.
- the rods will be between about 0.5 and 1.5 metres in length, and more typically between about 0.45 and 1 metre in length.
- pultruded glass reinforced plastic rods are about 620 mm in length.
- equation 5 is plotted in Figure 7 for the range of rod stiffnesses expected, being 400N/m to 1200N/m, but nominally 700N/m. This is for glass reinforced pultruded rods. Other materials need another plot to define the length to diameter.
- Figure 7 shows the combinations of rod length and rod diameter that will give
