[0224] The trampoline park 10 illustrated in FIG. 1 may be considered as a trampoline system, trampoline field or trampoline park or for use in a trampoline park. The trampoline includes a frame 01 supported on a floor 02 or other foundation. Biasing means is mounted on or to said frame or other foundation and is described in more detail later. A plurality of jumping mats shown typically at 03 is connected to selected first ones of the biasing means 04 above the frame or other foundation in side by side relationship, the selected first ones of the biasing means being arranged around the periphery of the plurality of jumping mats to bias the plurality of mats outwards to tension the mats. The mats are operatively connected to each other along respective edge portions thereof shown typically at 05, and selected second ones of the biasing means are mounted on or to the frame or other foundation below said plurality of mats. Adjacent mats are connected to each other along adjacent portions by selected third ones of the biasing means and arranged to bias adjacent mats towards each other. The second ones of the biasing means are located below the connections between the mats as described in more detail in respect of FIGS. 2a to 2d. The third ones of the biasing means are illustrated in more detail in FIGS. 4a to 6.
[0225] An oblique wall 06 surrounds most of the trampoline leaving an access opening in one side. The oblique wall is formed of trampoline jumping mats supported and connected in similar arrangement to the plurality of jumping mats, but at an oblique angle extending upwards from the edge of the trampoline. A safety wall or net 07 is mounted to the upper edges of the oblique trampolines.
[0226] The first ones of the biasing means are mounted to the frame to form a trampoline support frame 20 illustrated in FIGS. 2a to 2d. The trampoline support frame includes a plurality of hoop springs shown typically at 13 spaced substantially regularly from each other along a hoop axis and also being substantially parallel to each other. The hoop springs are supported on a frame member 27, each hoop spring being fastened to the frame member by a bolt shown typically at 28.
[0227] Each hoop spring has a laterally arranged coil spring shown typically at 11 interposed between two lateral straps shown typically at 12 in FIGS. 2a and 12a in FIG. 2b, the lateral straps and lateral spring coinciding substantially with the lateral diameter of the hoop spring. The lateral straps 12 shown in FIG. 2a are oriented substantially vertically, whereas the lateral straps 12a in FIG. 2b are oriented substantially horizontally. The hoops are each covered by a sleeve of webbing material and from which the lateral straps extend diametrically inwardly, also formed from webbing material. A metal plate shown typically at 17 is encased, preferably removably, in the lateral straps 12 of FIG. 2a for attachment of the coil springs which hold the straps in their diametral disposition across the hoop. The same arrangement is provided where the trampoline mats are arranged obliquely, the support frame being tilted at the appropriate angle.
[0228] Two parallel cables 16 as shown in FIG. 2a are fastened to a cable anchor described below in relation to FIGS. 3b and 8b. In an alternative arrangement shown in FIG. 2b an elongate stiffening member 14 is attached to the outside of the hoop springs substantially at an extension of the lateral diameter of each hoop, and substantially parallel to the frame member 27. Each stiffening member is in the form of a hollow pipe in the illustration shown, but it will be appreciated that the stiffening member could be of some other form selected according to the flexure characteristics of the joint and jumping mats. The stiffening members are resiliently displaced outwards from the centre of the hoops and downward when a person jumps on the mat or on the joint, there being a cover provided thereon as described hereinunder.
[0229] The edge frame support assembly 50 shown in FIG. 3a includes a lower frame member 51 supported above the ground extending substantially parallel to the edge of a trampoline mat (not shown), a peripheral frame member 52 supported in spaced disposition from the frame member upwardly and outwardly therefrom at an elevation substantially the same as the trampoline mat and an intermediate bar 52 supported substantially above the frame member and inwardly from the peripheral frame member.
[0230] The intermediate bar is supported in its position by a plurality of leaf springs shown typically at 54 extending upwardly from the lower frame member as well as by a plurality of coil springs 55 extending between the intermediate bar and the peripheral frame member and in register with the leaf springs. A plurality of flexible webs shown typically at 56 extend inward from the intermediate bar to the mat, the flexible webs being in register with the coil and leaf springs. The intermediate bar is of a selected flexibility so that a force on the mat near one of the leaf and coil springs is transmitted to adjacent leaf and coil springs by deflection of the mat. The flexible webs provide a soft edge to the trampoline mats, offering substantially no resistance to downward displacement in and of themselves. The coil springs have a short chain 57 interposed connecting them to the peripheral frame member. The relative lengths of the chain and the coil spring may be adjusted to change the bounce characteristics of the trampoline.
[0231] A lower oblique mat support member 58 runs parallel to the lower frame member inwardly therefrom and at substantially the same elevation. A plurality of oblique coil springs shown typically at 59 resiliently connect an oblique trampoline mat 60 to the frame oblique mat support member. The coil springs are preferably encased in a sleeve.
[0232] The joint and cover assembly illustrated in FIGS. 4a to 6 includes a frame support 20a of similar form to that illustrated in FIGS. 2a to 2d except that the elongate stiffening members or cables are absent and supplementary spring supports 18 extend from the lateral diametral points of the hoop springs to a supplementary frame member (not shown) running parallel to the frame member 27.
[0233] The adjacent jumping mats 21 are connected to each other by a plurality of mat joining springs 23 and a cover assembly is arranged to have a substantially inextensible central portion 24 interposed between two extensible strips 25, each extensible strip being interposed between an opposed edge of the central portion and a respective side strip 26. Each side strip also provides attachment to an edge of the appropriate jumping mat along a complementary attachment strip 29. The side strips and attachment strips preferably include hook and loop fastener strips, preferably all of the way along in order to provide sufficient adhesion of the cover assembly to the adjacent jumping mats.
[0234] The trampoline mat connector 30 illustrated in FIG. 7a includes a cover assembly 19 of stretchable material having one part of a hook and loop fastener 19a along each edge for engagement with the complementary part of the hook and loop fastener along the edges of the adjacent mats. A padding assembly 30 is interposed between the cover assembly and the upper portion of the hoop springs.
[0235] The padding assembly has two or three layers, a lower layer is in the form of an elongate strip extending along and between the edge of adjacent trampoline mats and having rectangular cavities (not shown) penetrating therethrough at regular intervals in register with the upper portions of the hoop springs. An upper layer 35 is bonded to the upper face of the lower layer and is provided in the form of discrete forms spaced from each other by the width of the coil springs joining the adjacent mats and having an overhang 36 at each end. The upper layer covers the rectangular penetrations in the lower layer. In the embodiment illustrated there are two coil springs between each adjacent pair of hoop springs.
[0236] The upper layer is bonded to the upper faces of the rectangular forms of the intermediate layer and is likewise composed of discrete forms, one for each of the rectangular forms of the intermediate layer, and are preferably rectangular, but more preferably having rounded or cut-off corners. The width is the same as the rectangular forms of the intermediate layer, but the length is selected to be that of the spacing between the edges of the adjacent mats of the trampoline, thereby overhanging the ends rectangular forms of the intermediate layer. Such an arrangement permits the upper layer to be displaced downward when the trampoline mat is displaced downwards under load. Preferably, each layer has the same thickness.
[0237] The alternative padding assembly 30a illustrated in FIG. 7d includes an elongate top cover pad 31 to which are bonded a plurality of pads in spaced relationship from each other along the length of the underside. In a typical arrangement, the top cover pad is of a length commensurate with the length of the edge of the trampoline mats being joined together. The springs joining the mats together are spaced alternately at wide and narrow spacings, the wide spacings being about twice the width as the narrow spacings. The filler pads are sized correspondingly, and are referred to for convenience as wide pads shown typically at 32 and narrow pads 33 shown typically at 33. The spacing between the filler pads is selected to provide good clearance from the springs passing between them. The clearance is selected to accommodate possible linear displacement of parts of the padding assembly due to displacement of the mat under load.
[0238] The cover assembly 40 illustrated in FIG. 7e has a main cover strip 41 of stretchable material having a strip of hook and loop along each edge for firm, but temporary, fastening to the edges of adjacent mats. A high visibility strip 42, also being stretchable, may be fastened atop the main cover strip if desired for indicating the joint between adjacent mats. The high visibility strip 42 is shown partly unrolled on top of the main cover strip, the remainder of the high visibility strip for that length of the joint being shown in a roll 43.
[0239] The cover strips are formed from a material which is stretchable in one direction, but substantially non-stretchable in the other direction. For locations where the joints between mats meet at a three-way or four-way intersection, the material used for the cover assembly is stretchable in both directions. Because the cover assembly is subject to frictional contact with other elements of the trampoline connector according to the invention, it is readily replaceable by virtue of the hook and loop fasteners.
[0240] The corner mounting arrangements 80 for oblique trampoline mats illustrated in FIG. 8a shows the arrangement for two oblique trampoline mats 81 extending upward from the edges of the joined trampoline mats shown generally at 21. The corner also shows two edge frame support assemblies intersecting without necessarily meeting at a right-angle corner. Two oblique frame members 82 are mounted to the floor 83. A plurality of spring and chain assemblies shown typically at 86 connect respectively to the edge each oblique trampoline mat, crossing over or under each other to keep the mats resiliently taught. The corner between the mats forms a sloping valley, the oblique trampoline mats in the corners being trapezoidal to accommodate the sloping valley.
[0241] The underside 90 of the trampoline shown generally in FIG. 8b shows a safety net 91 secured to the underside of the obliquely mounted trampolines. Further safety nets are mounted to the underside of the horizontal trampoline mats in similar fashion. A cable anchor 92 is provided at each end of the frame member to extend through the hoops. The cables each penetrate the metal plate of each lateral strap 12 as shown in FIG. 1a. The cable anchor is provided on each oblique frame member 93 supporting the trampolines mats which are at an oblique angle. The arrangement permits part of the deflection of one hoop spring under load to be taken up by one or more adjacent hoop springs along the hoop axis and extending from either side where an adjacent hoop spring is provided. The cables may be tightened to the required tension by a turnbuckle 94 having a nut 95 threadedly engaged therewith.
[0242] The trampoline mat connector 1010 illustrated in FIG. 9 includes a connecting layer 1011 in the form of an elongate strip of substantially inextensible material. The connecting layer has a plurality of connecting tabs 1012 in regularly spaced arrangement along the underside, one of which is shown. The connecting tabs are smaller strips which are elongate in the same direction as the elongate dimension of the connecting layer. Each connecting tab is detachably connectible to one of a plurality of round springs 1013, one of which is shown. The round springs are also in regularly spaced arrangement along a frame axis which extends in the same direction as the elongate dimension of the connecting layer. The round springs are of circular form as described in our international application No. PCT/AU2015/000398 (our earlier application). The connecting tabs are formed from hook and loop fastener material. The connecting layer also has an attachment strip 1014 running along each side edge on the upper face in the form of a strip of hook material for a hook and loop fastener. The arrangements of the present invention may be applied to the trampoline described in our earlier application for both the horizontal trampoline mats and the sloping or oblique trampoline mats.
[0243] A padding layer 1015 is disposed above the connecting layer and is also in the form of an elongate strip, but the padding layer is narrower than the connecting layer by at least the width of the attachment strip. A joining layer 1016 is disposed above the padding layer and a width greater than that of the padding layer, the width being about the same as that of the connecting layer. A complementary attachment strip 1017 is provided on the lower side along each side edge for detachable attachment to the attachment strip of the connecting layer. When the attachment strip and complementary attachment strips are attached to each other, an elongate passage is provided for retaining the padding layer between the connecting layer and the joining layer.
[0244] The joining layer also has a primary retaining strip 1018 on the upper side along each side edge. A cover layer 1019 is disposed above the joining layer and has a width greater than that of the joining layer and a secondary retaining strip 1020 on the lower side along each side edge. The retaining strips are also provided in the form of the hook material for a hook and loop fastener. The joining layer is illustrated in FIG. 8 in two parts having a gap in between, but the joining layer may be a contiguous layer.
[0245] Two adjacent trampoline mats 1021 each have a complementary retaining strip on both the upper and lower faces at 1022 and 1023 respectively along at least part of the adjacent edges for engagement between the primary and secondary retaining strips of the joining and cover layers. By this arrangement, the mats may be joined to each other and connected to at least some of the springs.
[0246] The alternative trampoline connector illustrated in FIG. 14 has some of the same elements as the trampoline connector illustrated in FIGS. 9 to 11, those elements in common having the same reference numerals. However, a central strip 1024 is interposed between the two sides of the connector to permit the connector to stretch in the transverse direction, that is, in the direction substantially at right angles to the elongate axis of the connector. In the modification illustrated in FIG. 14, a first overlap strap 1025 and a second overlap strap 1026 are provided to connect the connector to the springs of the trampoline frame.
[0247] The trampoline park 1030 illustrated in FIG. 15 and in part in FIG. 16 has a plurality of trampolines arranged with their mats in edge to edge abutting or adjacent relationship, being joined to each other by the connectors of the present invention. The trampoline park has a support rail 1027 supporting the springs and being elevated by a plurality of regularly spaced frame supports 1026 as illustrated in FIGS. 18 and 19. The support rail also meets with extended uprights 1028 to support the upper edge of obliquely arranged trampolines. The obliquely arranged trampolines have their springs mounted to oblique support rails 1029 in similar fashion to those of the horizontal support rail shown at 1027.
[0248] Alternative arrangements for mounting the hoop springs are shown in FIGS. 20 and 21. At the joints between two coplanar trampolines, as illustrated in FIG. 20, the springs are inserted into the hollow passage of the support rail through a slit or slot and fastened in place by a fastener 1028. As shown in FIG. 24, there is provided a first connecting strip 1031 and a second connecting strip 1032, the first connecting strip being taken around the spring and fastened in place by the second connecting strip. The first and second connecting strips are comprised of a complementary pair of hook and loop fastening strips.
[0249] The trampoline 810 illustrated in part in FIGS. 25 and 26 has a relatively rigid connector 860 used to connect the mats 821 as will be described in more detail later. Additionally, the two mats have an elastic edge portion 821a at their adjoining edges. The leaf springs 827 at the connecting portion of the two mats 821 are similar to the leaf springs illustrated our co-pending international application No. PCT/AU2015/000398 in that they are generally cylindrical in form, although they are not helical but instead have their free ends aligned. However, in trampoline 810, the cylindrical leaf springs 827 have their free ends secured in the centre mounting frame member 820 and the upper centre portion of each spring referenced as item 840 rests in a slot 861 provided in the connector housing 862.
[0250] The connector housing 862 is constructed of a rigid plastics material and has a longitudinally extending cavity 864 provided therein (in the direction of the edges of the mats to be connected). The cavity opens upwards towards the mat at longitudinal opening 865 to allow the two mat edge portions to be fitted therethrough. The cavity also opens to the opposite end faces 866 and 867. As can be seen in FIGS. 25 and 26, the connector includes two longitudinally extending slightly flexible but resilient tubes 871 and 872 (formed of a hardened rubber compound) which rest in the cavity 864 in slightly spaced apart relationship and the edge portions of the two mats are fitted over the respective tubes and engage in slots 871a and 872a provided therein. It will be appreciated that the outer face of the tubes engage the inner face of the cavity 864 so as to inhibit rolling of the tubes and the upper opening 865 is sized to prevent the tubes rolling out of the cavity. Notably, the tubes 871 and 872 are shaped to provide relatively sharp corners 871b and 872b to sharpen the corners of the mat thereby providing a somewhat invisible joint.
[0251] The edge portions of the mats are also respectively held in their rubber tubes by flexible fibreglass rods 873 and 874 which have slots 873a and 874a provided therein along their lengths. Notably, rods 873 and 874 extend across the full length of the adjoining mats and connect all the mat connectors 860 connecting the mats 821 together. That is to say, the fibreglass rods 873 and 874 lock the respective mat edge portions in their respective rubber tubes 871 and 872 and also hold the connectors together although the flexibility of the fibreglass rods allows some relative movement between adjacent connectors. Suitably, in the trampoline 810 illustrated, the connectors are slightly spaced apart and a connector clip 874 is fitted to the two fibreglass rods 873 and 874 to hold them together between adjacent connectors thereby assisting the connector blocks to hold the two mats together. In this case, the clip is formed of two abutting steel tubes welded together but in other forms it could be manufactured of a suitable plastics material.
[0252] Another trampoline mat connector is illustrated in FIGS. 27 and 28. However, in this example, the mats 921 and 922 are held together by spaced apart strips 973 of hook and loop fasteners such as that commonly known as VELCRO extending fully along the joint with a cover strip 977 of mat fabric thereover which in turn is secured to the respective adjoining mats along both edges by zippers 978 and stitching 979 extending fully across the adjoining mats. In this case, instead of having hoop springs as in the trampolines of FIGS. 1 to 28, the biasing means at the joint region of the two mats includes an elongate hydrostatic air bag 927 extending fully across the two trampoline mats under the joint line and the mats are secured thereto by a wide strip of hook and loop fasteners 994 such as VELCRO.
[0253] As can be seen in FIG. 28 the hydrostatic air bag is secured to the frame member 920 by leaf springs 971 spaced apart along the length of the bag which in turn are secure to the bag by strips of hook and loop fasteners 972. Advantageously the leaf springs bias the bag to the centre of the frame member 920 as the bag tends to roll from side to side under the action of persons jumping on the adjacent mats and the bag accommodates jumping at the joint area while resiliently supporting the adjoining mats upwards.
[0254] The alternate connection shown in FIG. 29 also uses the hydrostatic air bag 927 but in this case an intermediate mat 981 is connected to the bag by hook and loop fasteners 973 and the two jumping mats 921 and 922 are connected to the intermediate mat by hook and loop fasteners 982 and 983. The loops are may be formed by a strip of webbing cloth which is stitched to the mat on its underside in a broken manner to provide spaced apart sleeves for the leaf springs. This arrangement is particularly advantageous with continuous mats and is relatively simple.
[0255] In use, trampolines according to the invention may be assembled into a trampoline park, court or field. Such a trampoline park provides more versatility for games such as dodgeball or soccer because the players are not confined to bouncing, landing, walking or standing on the jumping mats themselves.
[0256] The foregoing description has been given by way of illustrative example of the invention and many modifications and variations which will be apparent to persons skilled in the art may be made without departing from the spirit and scope of the invention as claimed in the following claims.
