Description

SAFETY NET FOR A TRAIVIPOLINE, A TRAIVIPOLINE AND A METHOD FORARRANGING A SAFETY NET IN A TRAIVIPOLINE TECHNICAL FIELD The present disclosure relates to a safety net adapted to surround a trampoline mat of atrampoline. The disclosure further relates to a trampoline comprising such a safety netand to a method of arranging a safety net in a trampoline.

BACKGROUND A trampoline comprises a trampoline mat, a frame and at least one resilient member. Thetrampoline mat is typically circular, oval, square or rectangular. The trampoline mat maycomprise a cloth or net-shaped structure. lt may be made of a polymeric material, such aspolypropylene. The frame is normally made of metal. lt encompasses the trampoline matand typically has substantially the same shape as the trampoline mat. A circular or ovaltrampoline mat is then surrounded by a circular or oval frame having a larger diameterthan the trampoline mat, and a square or rectangular trampoline mat is surrounded by asubstantially square or rectangular frame, which however may comprise rounded-offedges.

The trampoline mat typically comprises a plurality of attachments distributed along theedge of the trampoline mat. The attachments are adapted to receive one or more resilientmembers for retaining the trampoline mat under tension. The resilient members may be aplurality of springs, e.g. helical springs, connecting the edge of the trampoline mat to theframe, thereby tensioning the trampoline mat. When a person is using the trampoline mat,i.e. jumping on it, the springs will be extended and thereafter strive to go back to theirnormal lengths. The spring may be attached to a loop, such as a D-shaped or triangle-shaped ring, comprised in the trampoline mat by means of a hook comprised in the spring.

As an alternative, the resilient member may comprise an elastic cord. Normally, the elasticcord is long enough to go back and forth between the edge of the trampoline mat and theframe a couple of times. Each portion connecting the trampoline mat to the frame then forms a segment, which correspond to a spring in the above example. The elastic cordmay be so long, that only one elastic cord is utilized for the whole trampoline mat, or aplurality of elastic cords may be used.

The trampoline mat is often surrounded by an edge pad, which is adapted to at leastpartly cover the at least one resilient member and/or the frame. The edge pad will helppreventing a user from stepping or landing between the resilient members, e.g. whenclimbing onto the trampoline mat. The edge pad may also be arranged to cover the frame,thereby dampening a possible impact with the frame in case of stepping or landing on theframe. The edge pad is often made as a number of segments, the shapes of which areadapted to the frame and the trampoline mat. For a circular or oval trampoline mat, thesegments may therefore be arc-shaped. For a square or rectangular mat, rectangularsegments may be used. lt is further known to use a safety net in order to prevent a user from falling off thetrampoline mat. The safety net is retained by a safety net retainer, e.g. a number ofsupport poles extending upwardly from the frame for carrying the safety net surroundingthe trampoline mat. The safety net may be attached to the trampoline mat. This helps toprevent the user from stepping on or between the resilient members.

However, even if using a safety net attached to the trampoline mat in a conventional way,there is still a risk that a foot or an arm of the user, e.g. if landing unfortunately in thevicinity of the edge of the trampoline mat, would slip out between the trampoline mat andthe safety net, e.g. in the interspace between two attachments of the resilient member tothe trampoline mat. lf this would occur, there is a risk of discomfort and even injury to theuser of the trampoline. ln order to reduce this risk, it has been suggested to sew the safety net to the trampolinemat in the vicinity of the edge of the trampoline mat. However sewing is quite cumber-some, especially since it is made after the trampoline has been mounted, such that thesewing can be made over the attached resilient members.

SUMMARY The object of the present disclosure is to overcome or ameliorate at least one of thedisadvantages of the prior art, or to provide a useful alternative.

The object above may be achieved by the subject-matter of claim 1. Embodiments are setforth in the appended dependent claims, in the following description and in the drawings.

Thus, the present invention relates to a safety net adapted to surround a trampoline matof a trampoline. The safety net comprises a protection portion adapted to prevent a userfrom falling off the trampoline mat and an attachment portion allowing attachment of atleast one resilient member to the trampoline mat through the attachment portion, theresilient member being adapted to retain the trampoline mat under tension. The safety netfurther comprises an edge portion and a fold zone, being adapted to be folded around anedge of the trampoline mat. The edge portion and the protection portion are located onopposite sides of the fold zone. The edge portion comprises one or more extensiondiminishing means for tightening of the edge portion.

The safety net has a first direction forming a height direction when mounted to thetrampoline mat and a second direction perpendicular to the first direction and forming acircumferential direction when mounted to the trampoline mat. Before mounting the safetynet to the trampoline mat, the safety net may a substantially rectangular shape. ln thatcase, the second direction could correspond to an x-direction and the first direction couldcorrespond to a y-direction, the y-direction being perpendicular to the x-direction.

When mounted in the trampoline, the protection portion of the safety net is retained by thesafety net retainer in a way common in the art, such that it extends in the first direction_The protection portion is adapted to prevent a user from falling off the trampoline mat.

The attachment portion allows attachment of the at least one resilient member to thetrampoline mat through the attachment portion. lt is common to arrange the above-mentioned attachments for the at least one resilient member at the edge of the trampolinemat, e.g. D-shaped or triangle-shaped rings, but it would also be possible to arrange theattachments for the at least one resilient member at the upper side in the vicinity of theedge or at the underside in the vicinity of the edge of the trampoline mat.

The safety net further comprises an edge portion and a fold zone. The fold zone isadapted to be folded around the edge of the trampoline mat. Hence the width w of the foldzone is preferably adapted to the thickness of the edge of the trampoline mat, whichtypically is in the range of from 1 to 10 mm, e.g. in the range of from 2 to 5 mm. Thethickness of the trampoline mat itself is typically in the range of from 0.2 mm to 1 mm,such as in the range of from 0.3 mm to 0.6 mm, or in the range of from 0.4 mm to 0. 5mm.However, the trampoline mat is usually reinforced at the edge, resulting in a higherthickness at the edge. The width w is determined in the first direction of the safety netassuming the safety net is in an untensioned state. The edge portion and the protectionportion are located on opposite sides of the fold zone.

When the safety net is mounted in the trampoline, the edge portion is located under thetrampoline mat, i.e. vertically below and laterally inside the edge of the trampoline mat.The width b of the edge portion may be in the range of 0 cm < b s 50 cm, preferably 2 cms b s 30 cm, more preferably 5 cm s b s 20 cm. The width b is determined in the firstdirection of the safety net assuming the safety net is in an untensioned state.

There may be a minimum distance d between the fold zone and the extension diminishingmeans in the range of 0 cm < d s 40 cm, preferably 1 cm s d s 20 cm, more preferably 2 cm s d s 10 cm. The minimum distance is the least distance between the fold zone andthe extension diminishing means. The minimum distance d is determined in the first direction of the safety net assuming the safety net is in an untensioned state.

When the safety net is mounted in the trampoline and if the trampoline mat is circular, theminimum distance may be determined in the radial direction of the trampoline mat. If thetrampoline mat has a non-circular shape, e.g. square or rectangular, the minimum distance may be determined perpendicularly to the edge of the trampoline mat.

As mentioned above, it is common to arrange the above-mentioned attachments for the atleast one resilient member, e.g. the D-shaped or triangle-shaped rings, at the edge of thetrampoline mat. ln that case, the order of the portions of the safety net is, when starting ata lower edge: the edge portion, the fold zone, the attachment portion and the protectionportion. ln that case, the attachment portion of the safety net adjoins the protection portionand the fold zone delimits the edge portion from the attachment portion. This would also be the order if the attachments for the at least one resilient member were located at theupper side of the trampoline mat.

As an alternative, the attachments for the at least one resilient member, e.g. the D-shapedor triangle-shaped rings, may be arranged at the underside of the trampoline mat. ln thatcase, the order of the portions of the safety net is, when starting at a lower edge: the edgeportion, the attachment portion, the fold zone and the protection portion. ln that case, theattachment portion of the safety net adjoins the edge portion and the fold zone delimitsthe protection portion from the attachment portion.

A portion of, or the whole of, the edge portion may be of another material than the rest ofthe safety net. ln that case, the edge portion may be joined to the rest of the safety net bymeans of sewing, welding and/or an adhesive. Also the fold zone and/or the attachmentportion may be of another material than the rest of the safety net. The edge portion, thefold zone and/or the attachment portion may comprise reinforcements.

The edge portion comprises one or more extension diminishing means, which areprovided to be able to tighten the edge portion, thereby being able to obtain a desiredlocation of the edge portion in the mounted trampoline, i.e. under the trampoline mat.Thereby it is ascertained that even if a user of the trampoline accidentally would step orland at the edge of the trampoline mat, there would not be any risk that his/her foot or armwould slip out in between the safety net and the trampoline mat, since the folded positionof the edge portion results in that such a foot or arm would instead land in the safety net,probably in the fold zone. Further, since the edge portion can be tightened by means ofthe one or more extension diminishing means, it is quick and easy to obtain the desiredsafety.

The attachment portion may comprise a first plurality of apertures distributed along theattachment portion, preferably evenly distributed along the attachment portion, allowingattachment of the at least one resilient member to the trampoline mat through theapertures of the first plurality. The apertures of the first plurality are then distributed alongthe attachment portion as seen in the second direction. The first plurality of aperturesallows passage of the above-mentioned loops, e.g. D-shaped or triangle-shaped rings, forattachment of the at least one resilient member. The first plurality of apertures may beprovided by the normal openings in the safety net or may be purposely shaped apertures.

The safety net may further comprise a tightening strap and the extension diminishingmeans of the edge portion may be located along the edge portion, preferably evenlydistributed along the edge portion. The tightening strap is adapted to be connected to theextension diminishing means such that the tightening strap is adapted to tightening of theedge portion. The extension diminishing means are distributed along the edge portion asseen in the second direction. When the tightening strap is tightened, it also tightens theedge portion, thereby obtaining the desired location of the edge portion under thetrampoline mat, i.e. vertically below and laterally inside the edge of the trampoline mat.The tightening strap may be elastic. A single tightening strap may be used around thewhole circumference of the trampoline mat or a plurality of tightening straps may be used.The tightening strap may comprise a quick-lock, such that the tightening strap quickly andeasy can be locked relative to the extension diminishing means, when the edge portionhas obtained its desired position. As an alternative or a complement, the tightening strapmay be tied to itself, when the edge portion has obtained its desired position. As yet analternative the tightening strap may comprise a belt and a buckle, such that it can bebuckled up at the desired length. The tightening strap may be comprised in the safety net,e.g. being attached to it at at least one location, or the tightening strap may be a separate unit.

The extension diminishing means may comprise a second plurality of aperturesdistributed along the edge portion, preferably evenly distributed along the edge portion,the tightening strap being adapted to go through the apertures of the second plurality. Theapertures of the second plurality are distributed along the edge portion as seen in thesecond direction. The second plurality of apertures may be provided by the normalopenings in the safety net or may be purposely shaped apertures.

The number of apertures of the second plurality may be the same, less than or more thanthe number of apertures of the first plurality. Further, the positions of the apertures of thesecond plurality relative to the positions of the apertures of the first plurality as seen in thesecond direction may be the same or different. However, it has been found appropriate touse the same number of apertures for the first and second plurality and to locate thempain/vise, i.e. one aperture under the other.

As an alternative, or a complement, the extension diminishing means may comprise achannel extending along the edge portion, the tightening strap being adapted to gothrough the channel. The channel extends in the second direction. The channel maycomprise, or be constituted by a hem of the material of the safety net. Alternative, thechannel may be made in a reinforcement of the edge of the edge portion.

As yet an alternative, or a complement, the extension diminishing means may comprise ahook portion or a loop portion of a hook-and-loop attachment, a portion of a snap-inconnection or a button connection. ln that case, the trampoline mat is preferably providedwith a corresponding receiving means adapted to cooperate with the extensiondiminishing means of the edge portion. Since the edge portion thereby is attached to theunderside of the trampoline mat inside the edge of the trampoline mat, the edge portion istightened in relation to the edge of the trampoline mat. Thereby it is possible to obtain thedesired location of the edge portion in the mounted trampoline, which is under thetrampoline mat, i.e. vertically below and laterally inside the edge of the trampoline mat.

The invention further relates to a trampoline comprising a trampoline mat, a frame,adapted to encompass the trampoline mat, at least one resilient member, adapted toretain the trampoline mat under tension and being connectable between the trampolinemat and the frame, a safety net as described herein, adapted to surround the trampolinemat in order to prevent a user from falling off the trampoline mat, and a safety net retainer,adapted to retain the safety net. The at least one extension diminishing means of theedge portion of the safety net is/are adapted to retain at least a portion of the edge portionin a position wherein the fold zone of the safety net is at least partly folded around anedge of the trampoline mat. ln the trampoline according to the invention, it is possible to obtain a desired location ofthe edge portion in the mounted trampoline, which is under the trampoline mat, i.e.vertically below and laterally inside the edge of the trampoline mat.

Optionally, the trampoline comprises at least one edge pad, the edge pad being adaptedto at least partly cover the at least one resilient member and/or the frame. ln the trampoline, and when the edge portion is tightened, the safety net of the invention ismounted such that a first distance between at least one of the extension diminishing means and a centre of the trampoline mat is less than a second distance between theedge of the trampoline mat and the centre of the trampoline mat. The second distance isdetermined at a location of the edge having the least distance to the extension diminishingmeans from which the first distance is determined. lf the trampoline mat has a circuiarshape, the first and second distances are determined in the radial direction. lf thetrampoline mat has a non-circuiar shape, e.g. square or rectanguiar, the first and seconddistances may be determined perpendicularly to the edge of the trampoline mat.Preferably, the first distance is less than the second distance around the whole orsubstantially the whole circumference of the trampoline mat.

The fold zone is folded around the edge of the trampoline mat, preferably around thewhole or substantially the whole circumference of the trampoline mat. ln the fold zone, the safety net may change direction by at least 30 °, preferably at least45 °, more preferably at least 60 °, most preferably 90° or substantially 90°. ln case the safety net comprises the above-mentioned tightening strap, the tighteningstrap may be arranged to move the extension diminishing means of the edge portion ofthe safety net closer to the centre of the trampoline mat when the tightening strap istightened. The tightening strap may be comprised in the safety net or it may be a separate unit.

An underside of the trampoline mat may comprise one or more receiving means adaptedto cooperate with the extension diminishing means of the edge portion, such as theabove-mentioned hook portion or a loop portion of a hook-and-loop attachment, a portionof a snap-in connection or a button connection. Purely as an example, one of theextension diminishing means of the edge portion or one of the receiving means of thetrampoline mat may be a hook portion of a hook-and-Ioop attachment and the other a loopportion.

The invention also relates to a method of arranging a safety net as described herein in atrampoline as described herein, the method comprising - attaching the at least one resilient member betvveen the trampoline mat and the frame, such that the at least one resilient member extends through the attachment portion of thesafety net thereby retaining the trampoline mat under tension, - tightening the edge portion by means of the extension diminishing means, such that atleast a portion of the edge portion of the safety net obtains a position wherein the foldzone of the safety net is at least partly folded around an edge of the trampoline mat.

Thereby, it is possible to obtain a desired location of the edge portion in the mountedtrampoline, which is under the trampoline mat, i.e. vertically below and laterally inside theedge of the trampoline mat.

The step of tightening may be performed by means of tightening the tightening strap.

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. Detailsfrom 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 trampoline mat 3, a frame 5, a plurality of resilient members 7, illustrated ashelical springs, a safety net 9, a safety net retainer 11 and an edge pad 13. ln Figure 2,the safety net 9 and the safety net retainer 11 are removed for visibility reasons to showdetails of the trampoline mat 3, the resilient members 7 and the edge pad 13. A firstdirection D, forms a vertical direction and a second direction D2 perpendicular to the first direction D, forms a circumferential direction.

The trampoline mat 3 is intended for jumping. lt is encompassed by the frame 5. Theframe 5 comprises legs 15, such that the trampoline 1 stands on the ground via the legs15. The edge pad 13, which may be divided into segments, covers the resilient members7 and the frame 5, which is best seen in Figure 2. ln the illustrated embodiment, thetrampoline mat 3 and the surrounding frame 5 are shown as circular, but they may also bee.g. oval, square or rectangular.

The trampoline mat 3 is retained in tension by the resilient members 7. The resilientmembers 7 are attached at or adjacent to an edge 17 of the trampoline mat 3 by means ofattachments, e.g. D-shaped or triangle-shaped rings 19. When the trampoline 1 ismounted, as in Figures 1 and 2, and nobody uses it, the trampoline mat 3 is in asubstantially flat state, having an upper side 21 and an underside 23.

The safety net 9 comprises a protection portion 25 adapted to prevent a user from fallingoff the trampoline mat 3. The protection portion 25 is retained by the safety net retainer 11in a way common in the art, such that it extends in the first direction D, Figures 3-8 illustrate details of a couple of different embodiments of a safety net accordingto the invention. The details illustrate a lower portion of the safety net before the safety netis mounted in the trampoline 1. 11 The lower portion illustrated in Figures 3-7 comprises an attachment portion 27 adjoiningthe protection portion 25. The attachment portion 27 allows attachment of the resilientmembers 7 to the trampoline mat 3 through the attachment portion 27. The attachmentportion 27 is therefore provided with a first plurality of apertures 29, which are distributedalong the attachment portion 27 as seen in the second direction D2, preferably evenlydistributed. The first plurality of apertures 29 allows passage of the above-mentioned D-shaped or triangle-shaped rings 19 for attachment of the resilient members 7. The firstplurality of apertures 29 may be provided by the normal openings in the safety net 9 ormay be purposely shaped apertures as illustrated in Figures 3-7.

The safety net further comprises an edge portion 31, which is delimited from the attach-ment portion 27 by a fold zone 33. The fold zone 33 is adapted to be folded around theedge 17 of the trampoline mat 3. Hence the width w of the fold zone 33 is preferablyadapted to the thickness of the edge 17 of the trampoline mat 3, which typically is in therange of from 1 to 10 mm, e.g. in the range of from 2 to 5 mm. The thickness of thetrampoline mat itself is typically in the range of from 0.2 mm to 1 mm, such as in the rangeof from 0.3 mm to 0.6 mm, or in the range of from 0.4 mm to 0. 5mm. However, thetrampoline mat is usually reinforced at the edge, resulting in a higher thickness at theedge. The measures of the width w of the fold zone 33 given herein are determined whenthe safety net 9 is in an untensioned state.

When the safety net 9 is mounted in the trampoline 1 according to the invention, asillustrated in Figures 1 and 2, the edge portion 31 is located under the trampoline mat 3,i.e. vertically below and laterally inside the edge 17 of the trampoline mat 3. The width b ofthe edge portion 31 may be in the range of 0 cm < b s 50 cm, preferably 2 cm s b s 30cm, more preferably 5 cm s b s 20 cm. The measures of the width b of the edge portion 31 given herein are determined when the safety net 9 is in an untensioned state.

The edge portion 31 comprises one or more extension diminishing means, which areprovided to be able to tighten the edge portion 31 , thereby being able to obtain thedesired location of the edge portion 31, i.e. under the trampoline mat 3. Thereby it isascertained that even if a user of the trampoline 1 accidentally would step at the edge 17of the trampoline mat 3, there would not be any risk that his/her foot would slip out inbetween the safety net 9 and the trampoline mat 3, since the folded position of the edge 12 portion 31 results in that such a foot would instead land in the safety net 9, probably in thefold zone 33.

Figures 3-7 illustrate different variants of extension diminishing means. The illustratedembodiments of Figures 3-5 and 7 have in common that the extension diminishing meansare adapted to cooperate with a tightening strap, which is further described in conjunctionwith Figure 11. When the tightening strap is tightened, it also tightens the edge portion 31,thereby obtaining the desired location of the edge portion 31, i.e. under the trampolinemat 3. With the measures given above for the edge portion 31, there is a minimumdistance d between the fold zone 33 and the extension diminishing means being in therange of 0 cm < d s 40 cm, preferably in the range of 1 cm s d s 20 cm, more preferably in the range of 2 cm s d s 10 cm. ln the embodiments of Figures 3-5, the edge portion 31 is provided with a second pluralityof apertures 35, 37, 39, which are distributed along the edge portion 31 as seen in thesecond direction D2, preferably evenly distributed. The apertures 35, 37, 39 providepassages for the tightening strap. The number of apertures 35, 37, 39 of the secondplurality may be the same, less than or more than the number of apertures 29 of the firstplurality. Further, the positions of the apertures 35, 37, 39 of the second plurality relativeto the positions of the apertures 29 of the first plurality as seen in the second direction D2may be the same or different. However, it has been found appropriate to use the samenumber of apertures and locate them under each other, as illustrated in Figures 3 and 4.The second plurality of apertures 35, 37, 39 may be provided by the normal openings inthe safety net 9 or may be purposely shaped apertures as illustrated in Figures 3-5. ln the embodiment of Figure 6, the edge portion 31 is provided with patches 41 adapted toform a hook and loop configuration together with the underside 23 of the trampoline mat3, e.g. the patches 41 forming a hook member. The underside 23 of the trampoline mat 3may be suitable for attaching the patches 41 and/or the underside 23 of the trampolinemat 3 may be provided with mating patches, e.g. forming a loop member. As analternative, or a complement, other fastening arrangements known by the skilled personmay be provided, such as an adhesive, a button or a snap-in connection. One portion ofthe fastening arrangement may be provided on the side of the edge portion 31 facing thetrampoline mat 3 and a mating portion of the fastening arrangement may then be providedon the underside 23 of the trampoline mat 3. 13 ln the embodiment of Figure 7, the edge of the edge portion 31 is provided with a channel43 forming a passage for the tightening strap. The channel may comprise or beconstituted by a hem of the edge portion 31.

Figure 8 illustrate an embodiment of the safety net, which is adapted for a trampoline mathaving the attachments for the at least one resilient member, e.g. the D-shaped ortriangle-shaped rings, at the underside 23 of the trampoline mat 3. ln that case, the orderof the portions is, when starting at a lower edge of the safety net: the edge portion 31, theattachment portion 27', the fold zone 33' and the protection portion 25. Any one of theextension diminishing means described for the embodiments of Figures 3-7 would workalso with the embodiment of Figure 8. Similar as for the other embodiments of the safetynet 9, the attachment portion 27' allows attachment of the resilient members 7 to thetrampoline mat 3 through the attachment portion 27”. The attachment portion 27' istherefore provided with a first plurality of apertures 29 corresponding to those described inconjunction with Figure 3.

Figures 9 and 10 illustrate a first step of a method of arranging the safety net 9 asdescribed herein in the trampoline 1 as described herein. The method comprisesattaching the at least one resilient member, here the helical springs 7, betvveen thetrampoline mat 3 and the frame 5, such that the at least one resilient member extendsthrough the attachment portion 27 of the safety net 9. The arrows in Figure 9 indicate thatthe triangle-shaped ring 19 of the trampoline mat 3 is intended to be inserted through anaperture 29 of the first plurality. See also Figure 10 illustrating that the triangle-shapedrings 19 protrude through the apertures 29 of the first plurality providing first anchor pointsfor the at least one resilient member, here the helical springs 7. The at least one resilientmember retain the trampoline mat 3 under tension. The frame 5 provides second anchorpoints 44 for the at least one resilient member.

Figure 11 illustrates a subsequent step of the method: The trampoline 1 is seen frombelow showing the underside 23 of the trampoline mat 3. The edge portion 31 is tightenedby means of the extension diminishing means. This is illustrated in Figure 10 by thetightening strap 45 going through the apertures 37 of the second plurality. Whentightening the tightening strap 45, the edge portion 31 obtains the desired location, i.e.under the trampoline mat 3. The tightening strap 45 may be elastic. The fold zone 33 is 14 folded around the edge 17 of the trampoline mat 3. Thereby the safety net 9 changesdirection by at least 30 °, preferably at least 45 °, more preferably at least 60 °, mostpreferably 90° or substantially 90° in the fold zone 33, in Figure 11 illustrated assubstantially 90 °.

As is most easily gleaned in Figure 11, the safety net 9 of the invention is mounted suchthat a first distance R, between at least one of the extension diminishing means, hereillustrated as an aperture 37 of the second plurality, and a centre C of the trampoline mat3 is less than a second distance F12 between the edge 17 of the trampoline mat 3 and thecentre C of the trampoline mat 3, see also Figure 2. The second distance Rg isdetermined at a location of the edge 17 having the least distance to the extensiondiminishing means from which the first distance R, is determined. lf the trampoline mat has a non-circular shape, e.g. square or rectangular, the first R, andsecond R2 distances may be determined perpendicularly to the edge of the trampoline mat.

Further modifications of the invention within the scope of the appended claims arefeasible. As such, the present invention should not be considered as limited by theembodiments and figures described herein. Rather, the full scope of the invention shouldbe determined by the appended claims, with reference to the description and drawings.
