Definitions

  • the present disclosure relates to a trampoline, and in particular to a trampoline having a reduced gap distance between the rebounding mat and the surrounding frame assembly.
  • the modern trampoline is a well-known device having a lineage of over 80 years. Early forms arose as a training tool in gymnastics and diving, and were quickly adopted for use in schools for fighter pilots and astronauts. The use of trampolines in gymnastic competition has matured through the years, and is now a recognized Olympic sport.
  • trampoline systems Another area of concern in trampoline systems is the gap spacing between the frame and the rebounding mat.
  • Traditional trampoline systems generally incorporate a series of horizontally oriented spring elements within this gap.
  • a pad or other sheathing material is generally provided to cover the gap spacing, but such covers are prone to moving, or may displace if impacted on an angle.
  • a trampoline comprises a rebounding mat, a support frame that includes a mat- surrounding structure, and a plurality of mat support connectors, wherein each mat support connector extends between the rebounding mat and an anchor structure.
  • the mat support connector includes a flexible elongate first portion that extends in tension along a respective first axis from the rebounding mat towards the mat-surrounding structure.
  • the mat support connector changes direction at a transition surface on the mat-surrounding structure, and includes a flexible elongate second portion that extends in tension away from the transition surface along a respective second axis that is at a non-zero angle relative to the respective first axis.
  • Each mat support connector includes an elastic region at least a portion of which is outside of the first portion.
  • a trampoline includes a rebounding mat a support frame that includes a mat-surrounding structure; and a plurality of mat support connectors.
  • Each mat support connector has a first end that is connected to the rebounding mat and a second end that is connected to an anchor structure. Between the first and second ends of the mat support connector, the mat support connector engages a transition surface on the mat-surrounding structure to transition the mat support connector from extending along a first axis to extending along a second axis that is at a non-zero angle relative to the first axis.
  • the mat support connector includes an elastic region at least a portion of which is between the transition surface and the anchor structure.

  • the trampoline 10 has a plurality of mat support connectors 26 distributed around the rebounding mat 20 to support it on the support frame 22, as will be described in greater detail below.
  • the mat support connector 26 is shown in greater detail in Fig. 2.
  • the mat support connector 26 includes a flexible elongate first portion 28 that extends in tension along a first axis (shown at A1 ) from the rebounding mat 20 towards the mat- surrounding structure 24.

  • the mat support connector 26 includes an elastic region 35 at least a portion of which is outside of the first portion 28.
  • the elastic region 35 includes a compression spring 36 that drives a piston 40 away from the rebounding mat 20.
  • the piston 40 is moveable in a piston housing 34.
  • a first end of the compression spring 36 engages the piston 40 and a second end of the compression spring engages a housing stop 38 that is integrated onto the wall structure of the piston housing 34.
  • the compression spring 36 urges the piston 40 towards a limit surface on a first end cap 42 of the piston housing 34.
  • Tension in the first inelastic elongate segment 53 causes movement of the piston 40 towards the housing stop 38 to cause compression in the compression spring 36.
  • the housing stop 38 has an elongate segment pass-through aperture 56 therein to permit the pass-through of the first inelastic elongate segment 53, while preventing the pass-through of the compression spring 36.
  • the piston 40, the compression spring 36 and the piston housing 34 together make up a spring assembly 32.
  • the piston housing 34 may include a head portion 48 that serves to support the mat support connector 26 on the mat-surrounding structure 24. As shown, each piston housing 34 is securely registered in a corresponding seat, provided on the mat- surrounding structure 24. In particular, the piston housing 34 is dimensioned to fit within a shaped aperture 44, such that bearing surfaces 46a, 46b of the piston housing cap 48 are supported on an upper surface 50 of the mat-surrounding structure 24. The piston housing 34 may be secured in place using any suitable fastening means, such as one or more suitable fasteners, an adhesive or any other suitable fastening means.
  • the head portion 48 also provides a bearing pin 52 to transition the mat support connector 26 between the first and second axes at the mat-surrounding structure 24. In other words, the mat support connector 26 bends around the bearing pin 52 to transition from the first axis to the second axis.

  • the first inelastic elongate segment 53 has a first attachment end 54 that connects to the rebounding mat 20, by any suitable means, such as by forming a loop that extends around a structural peripheral cable 57 along the periphery of the rebounding mat 20. From the rebounding mat 20, the first inelastic elongate segment 53 extends along the first axis A1 in tension towards the mat-surrounding structure 24, bends around the bearing pin 52 and extends along the second axis A2 to connect at a second attachment end 58 to the piston 40.
