    FRAME SEG|/IENT FOR A MODULAR FRA|/IE SYSTEM FOR A TRA|/IPOLINE TECHNICAL FIELD The present disclosure relates to frame segment for a modular frame system for atrampoline. The disclosure further relates to a modular frame system for a trampoline and a trampoline comprising such a modular frame system.
    BACKGROUND OF THE INVENTION A trampoline comprises a trampoline mat, a frame and at least a resilient member. Thetrampoline mat is typically circular, oval, square or rectangular. The frame encompassesthe trampoline mat and typically has a similar shape as that of the trampoline mat. Acircular or oval trampoline mat is then surrounded by a circular or oval frame having alarger diameter than the trampoline mat, and a square or rectangular trampoline mat issurrounded by a substantially square or substantially rectangular frame, which however may comprise rounded-off edges.
    The trampoline mat typically comprises a plurality of attachments distributed along theedge or adjacent to the edge of the trampoline mat. The attachments are adapted toreceive one or more resilient members for connecting the edge of the trampoline mat tothe frame, thereby tensioning the trampoline mat. The trampoline mat is often surroundedby an edge pad, which is adapted to at least partly cover the at least one resilient memberand/or the frame. The edge pad will help preventing a user from stepping or landingbetween the resilient members, e.g. when climbing onto the trampoline mat. The edgepad may also be arranged to cover the frame, thereby dampening a possible impact withthe frame in case of stepping or landing on the frame. The edge pad is often made as anumber of segments, the shapes of which are adapted to the frame and the trampoline mat.
    Large trampoline mats, in particular large rectangular trampoline mats are commonly usedin sports for training and competition purposes. The length of such a large rectangular trampoline mat can be several meters, thus requiring a frame of even larger dimensions.
    Furthermore, a frame for a trampoline mat of such dimensions is required to withstandhigh loads. The frame is normally made of metal and consisting of a solid or hollowtubular member dimensioned to withstand the high loads to which it is subjected.
    This results in the frame normally being constructed from long, heavy, continuoussections. Thereby, such large trampolines are cumbersome and difficult to handle, notonly during mounting or set-up of the trampoline but especially When it comes totransportation of the trampoline, since it is complicated and expensive to transport such long or in other ways space consuming parts or sections.
    SUMMARY The object of the present disclosure is to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.
    One or more of the above objects may be achieved with a frame segment in accordancewith claim 1 or a modular frame system in accordance with any one of claims 12 to 16 ora trampoline in accordance with claim 17. Further embodiments are set out in the dependent claims, in the following description and in the drawings.
    Thus, the present invention relates to a frame segment for a modular frame system for atrampoline. The frame segment comprises a main body that has an extension in alongitudinal direction. The frame segment further comprises at least a first coupling meanslocated at or adjacent to a first end of the frame segment.
    The main body has a cross section extending in a plane defined by a first and a seconddirection. The first and second directions are perpendicular to each other and to thelongitudinal extension of the main body. A maximum extension of the cross section in thesecond direction is equal to or larger than 1.5 times, preferably 2 times, more preferably2.5 times, most preferably 3 times a maximum extension of the cross section in the first direction.
    The first direction extends in the vertical direction of the trampoline standing on flat groundand the second direction is parallel to/extends along the (horizontal) plane of thetrampoline mat. Thus the main body, that is the frame segment may be seen as lying inthe horizontal plane of the trampoline mat, having its smallest extension in the vertical (first) direction of the trampoline.
    The first couplings means is located at or adjacent to a first end of the frame segment such as within 20 cm, preferably within 10 cm from the end.
    The cross section of the main body may for example have a substantially oval orsubstantially rectangular shape. lt may also have an asymmetric shape, with the extension of the cross section in the first direction varying along the second direction.
    The extension of the cross section in the first direction may vary along the seconddirection of the cross section, wherein the cross section is asymmetric as seen in relationto a centre-line extending in said first direction. The centre-line is located at half of the cross section as seen in the second direction.
    The main body may comprise two parallel tubular members being connected to each other.
    The two parallel tubular members may be connected via one or more plates or bars located betNeen the two parallel tubular members.
    The tubular member may have a circular, elliptical, oval, square, rectangular or polygonal cross-section. lt may be hollow or solid.
    The two parallel tubular members may have different diameters, wherein the tubularmember being closest to the trampoline mat may have the larger diameter of the two tubular members.

    The flange panels as described herein may be attached perpendicular to the longitudinalextension of the main body. Thus the panel lies in a plane parallel to that of the cross section of the main body, defined by the first and second directions.
    Further, the flange panels as described herein may be have an asymmetric shape or formas seen in relation to a centre-line extending in the first direction. The centre-line islocated at half of the cross section as seen in the second direction. Thus, the flangepanels may reflect or have a corresponding asymmetry as the cross section of the main body may have.
    As disclosed herein, the upper portion of the flange panel as seen in the vertical directionmay have a substantially flat surface parallel with the horizontal plane of the trampolinemat. This reduces the risk of injury if a user was to step on, or land on, the frame, as well as makes it easier to place an edge pad to cover the frame.
    Further, the flange panels may comprise one or more through-going openings adapted toreceive a respective fastening means, e.g. a screw of a screwjoint. The through openingsmay be through-going holes in the panel. Alternatively, the flange panels may compriserecesses or notches formed in the periphery of the panel adapted to receive a respectivefastening means. Further, a larger number of through-going holes may be located in theportion of the flange panel being closest to the trampoline mat, than in the portion of theflange panel facing the periphery of the trampoline. This configuration of the through-going holes and thereby the fastening means for the flange joints is adapted to Withstand the loads the flange joint is subjected to.
    As an alternative or complement, the coupling means as disclosed herein may be configured as one end of a first tubular member being inserted into an end of another tubular member, Which end has a larger diameter than the end of the first tubular member.
    The frame segment as described herein may be configured such that the flange panelsconstitutes the ends of the frame segment, thus the main body is located between and de|imited by the respective flange panels at opposite ends of the frame segment.
    The flange panel as described herein may comprise two through-going ho|escorrespondingly sized to receive a respective tubular member. The tubular members maybe partly inserted into the corresponding through-going ho|es in the flange panel and may preferably be welded to the flange panels.

    BRIEF DESCRIPTION OF THE DRAWINGS The present invention will hereinafter be further explained by means of non-limiting examples with reference to the appended drawings wherein: Fig. 1 is a perspective view of a trampoline according to the invention; Fig. 2 shows a modularframe system according to the invention; Fig. 3a shows a straight frame segment according to the invention; Fig. 3b shows a corner frame segment according to the invention; Fig. 4a shows a cross section a flange joint according to the invention; Fig. 4b shows a flange panel of a flange joint according to the invention; and Fig. 4c shows a cross section of a main body of a frame segment according to the invention. lt should be noted that the appended drawings are not necessarily drawn to scale and thatthe dimensions of some features of the present invention may have been exaggerated for the sake of clarity.
    DETAILED DESCRIPTION The invention will, in the following, be exemplified by embodiments. lt should however berealized that the embodiments are included in order to explain principles of the inventionand not to limit the scope of the invention, as defined by the appended claims. Details from two or more of the embodiments may be combined with each other.
    Figures 1 and 2 illustrate a trampoline 1 according to the invention. The trampoline 1comprises a modular frame system 2 according to the invention which encompasses atrampoline mat 3. A plurality of resilient members 4, for example helical springs, connectsthe edge of the trampoline mat 3 to the modular frame system 2, thereby tensioning thetrampoline mat 3. The trampoline mat 3 is intended forjumping. When a person is usingthe trampoline mat 3, i.e. jumping on it, the springs will be extended and thereafter striveto go back to their normal lengths. The trampoline 1 may further comprise an edge pad,which may be divided into segments, that covers the resilient members and the modularframe system 2. ln Figure 2, only a modular frame system 2 according to the inventionand a trampoline mat 3 is illustrated for visibility of the details of the modular frame system2.
    The modular frame system 2 is in Figures 1 and 2 depicted as comprising support legs 5such that the trampoline 1 stands on the ground via the support legs 5. However, themodular frame system 2 may equally well be used without support legs 5, such as in aground trampoline. ln this case, the modular frame system 2 rests on the ground with ahole below the trampoline mat 3. This has the advantage that the hole in the ground overwhich the trampoline mat 3 is positioned can be shallower towards its outer edges than inthe centre, since the hole is not required to encompass support legs 5 and the trampoline mat 3 is most suppressed at its centre. This may greatly simplify the ground work. ln Figures 1 and 2 the trampoline mat 3 and the surrounding modular frame system 2 areshown as rectangular, but they may also be for example square. Thus, the dimensions ofthe modular frame system 2 may vary. However, there are some preferred dimensions oflength and width of a rectangular trampoline, which may be regarded as standard, mainlydue to rules of competition. A modular frame system 2 according to the invention maythus be regarded as particularly advantageous since it enables the construction ofdifferently sized trampolines from a limited number of types of frame segments. Since alarge trampoline for sports and competition typically has dimensions of several metres,another advantage of the modular frame system 2 according to the invention is that of greatly facilitating and reducing costs for transport of the trampoline.
    As illustrated in Figure 2 the modular frame system 2 comprises a plurality of framesegments 6 according to the invention, which will be described in more detail below. Theframe segments 6 are connected to each other via first and second coupling means 7, 8located at respective first and second ends 9, 10 of the frame segments 6 and form aclosed loop having a rectangular shape. With reference to Figures 2 and 3, a framesegment 6 is illustrated that comprises two parallel tubular members 11a, 11b being atleast partly connected to each other via a plurality of plates 12. Thus, the modular framesystem 2 may be viewed as comprising two rectangular closed loops, an inner tubularmember loop and an outer tubular member loop which are at least partly connected to each other via the coupling means 7, 8 and the plurality of plates 12.
    The frame segment 6 comprises coupling means 7, 8 located at each of the two ends 9,10 of the frame segment. ln the illustrated embodiment, the coupling means 7, 8 at eachend consists of a flange panel 13, to which the two parallel tubular members 11a, 11b arepermanently attached, for example by welding. Further, the flange panel 13 comprisesthrough-going openings 14 for fastening means, such as screws, such that two flangepanels 13 can be connected to each other and fixed by the fastening means thus forminga flange joint 15 between two frame segments 6. The advantage of having a flange jointcoupling between the frame segments as illustrated, or any other type of coupling that isformed by two parts or means having corresponding shapes will become evident and is further explained below.
    With reference to Figures 4a to 4c, a flange panel 13 of a flange joint 15 of a modularframe system 2 according to the invention is shown in detail. As disclosed, the flangepanel 13 have an asymmetric shape, thus mimicking to the cross section of the main body16 illustrated as two parallel tubular members 11a, 11b. The flange panel 13 has twothrough-going holes correspondingly sized to receive a respective tubular member 11a,11b. The tubular members are partly inserted into the corresponding holes in the flangepanel 13 and preferably welded to flange panel. Further the flange panel has a number ofthrough-going holes 14 for receiving fastening means of the flange joint 15. The holes arelocated around the position of the tubular members 11a, 11b. There are a larger numberof through-going holes surrounding the location of the tubular member 11b with thelargest diameter.
    This configuration of the through-going holes and thereby the fastening means for the flange joints reflect to loads to which the flange joint is subjected.
    The upper portion of the flange panel 13 as seen in the vertical direction has asubstantially flat surface 17 parallel with the horizontal plane of the trampoline mat. Thisreduces the risk of injury if a user were to step on or land on the frame, as well as makes it easier to place an edge pad to cover the frame.
    With reference to Figures 2 and 3, a complete rectangular modularframe system 2 isformed by connecting at least two types of frame segments 6: a first plurality of straight frame segments and a second plurality of corner frame segments. ln the embodiment illustrated in Figures 1 and 2, two types of frame segments 6 are used:a straight segment of a single length and a corner frame segment. ln the corner framesegment, the two parallel tubular members 11a, 11b comprise a respective curvedportion, which constitute a corner having a 90 degree angle. The tubular members 11a,11b thus extend in two directions perpendicular to each other, thereby forming a first anda second leg portion of the corner frame segment. The first leg portion of the corner framesegment is longer than the second leg portion of the corner frame segment. The cornerframe segment is reinforced by a cross beam 17 in the curved portion of the framesegment. The proportions between the length of the straight frame segment and thelength of respective first and second leg portions of the corner frame segment are such asto minimize the number of types of frame segments required to construct a complete rectangular modularframe. Having first and second coupling means 7, 8 that are identical, as in the case of the flange panels located at respective first and second ends 7, 8 of aframe segment 6 and constitutes the two parts of the flange joint 15 between two framesegments 6, further contributes to minimizing the number of types of frame segments 6required to complete a rectangular modularframe, since all frame segments are connectable to each other.
    With reference to Fig 3 a straight frame segment and a corner frame segment accordingto the invention are disclosed. As described above, a frame segment, whether straight orcurved comprise two parallel tubular members 11a, 11b at least partly connected to eachother. Preferably, the tubular members 11a, 11b are tubes, however, tubular memberswith a differently shaped cross-section are also feasible. The diameter differs between thetwo parallel tubular members. The tubular member 11b being closest to the trampolinemat has a larger diameter than the tubular member 11a forming the outer periphery of the frame. ln the illustrated embodiment the tubular members 11a, 11b of the straight frame segmentare connected by four plates 12 spaced apart along the longitudinal extension of theframe segment 6. Alternatively the two parallel tubular members 11a, 11b may beconnected by bars or a similar structure. The plates 12 may preferably be made of steel.The number of plates, the distance with which the plates are spaced apart taken ascentre-to-centre distance and/or the width of each plate may vary and depend foremoston the length of the frame segment and the loads the frame segment has to withstand. lnan embodiment according to the invention wherein flange panels constitute the first andsecond coupling means, the flange panels also act as a connection between the twoparallel tubular members, in addition to connecting frame segments to each other. ln analternative embodiment, the coupling means, i.e. the flange panels, may represent anadequate connection between the two parallel tubular members of the frame segmentsuch that no further connectors, e. g. plates, between the two parallel tubular members are required.
