Title: Recreational jumping system, inflatable wall-shaped drop stitch member, support structure, trampoline frame, and set of parts

The present disclosure relates to a recreational jumping system, comprising a trampoline having a substantially horizontally extending bounce mat, wherein the recreational jumping device further comprises a jump wall.

Such recreational jumping systems are known, and can for instance be found in indoor trampoline parks. The trampoline is then often positioned with one of its side edges along a wall or in a corner of the room such that two side edges of the trampoline are positioned along a wall. Usually, the wall, or at least a respective portion thereof that forms a jump wall surface, is then covered with resilient foam. During use of such a known recreational jumping system, a user jumping on the trampoline’s bounce mat can use the jump wall surface to perform tricks, for instance by walking up against the jump wall surface and/or taking off from said jump wall surface.

Although many people enjoy using such recreational jumping systems, these known systems cannot simply be used at home, such as for instance in one’s garden. In particular, often one has not available a dead wall along which one can position a trampoline, let alone a relatively soft dead wall or a dead wall which can be provided with resilient foam in a relatively simple manner. Further, people usually do not feel like building a brick wall in their garden in order to serve as a so-called jump wall, if only because such jump wall will block the view and should be firm enough to withstand storms and the like.

It is an object of the present disclosure to provide an alternative recreational jumping system. In particular, it can be an object of the present disclosure to provide an alternative recreational jumping system comprising a trampoline and a jump wall. More in particular, it can be an object of the present disclosure to provide a recreational jumping system comprising a trampoline and a jump wall, wherein at least one of the disadvantages of a prior art recreational jumping system comprising a trampoline and a jump wall is counteracted. Yet more in particular, the present disclosure may aim to provide a recreational jumping system comprising a trampohne and a jump wall, wherein at least one of the disadvantages mentioned above is counteracted. In embodiments, the present disclosure may aim at providing a recreational jumping system comprising a trampoline and a jump wall, which system is intended and suitable for home use, especially outdoor use at home, in particular relatively safe home use, preferably without the need of providing a brick wall or other substantially permanent and/or relatively heavy wall. In embodiments, the present disclosure may aim at providing a recreational jumping system having a jump wall which can be installed relatively easily, and/or which can be removed relatively easily, preferably in a manner facilitating that it can be reinstalled relatively easily.

Thereto, the present disclosure provides for a recreational jumping system, comprising a trampoline having a substantially horizontally extending bounce mat, wherein the recreational jumping device further comprises a jump wall having an inflatable wall-shaped drop stitch member defining a jump wall surface, said jump wall surface extending under an angle with the bounce mat, said jump wall surface being located above the bounce mat, and said jump wall surface facing substantially towards an area above said bounce mat, such that during use of the recreational jumping system a user jumping on the trampoline’s bounce mat can use the jump wall surface to perform tricks, for instance by walking up against the jump wall surface and/or taking off from said jump wall surface.

By providing a jump wall having an inflatable wall-shaped drop stitch member defining a jump wall surface, a jump wall can be provided that on the one hand, for instance when the inflatable wall-shaped drop stitch member is inflated to about 7 to 10 bar, can provide a very rigid jump wall surface due to the drop stitch material, and which jump wall on the other hand, when not in use, can be brought into a state in which, in particular when the inflatable wall-shaped drop stitch member is deflated, it can be relatively small and/or relatively light-weight, which may facilitate transport and/or storage. For example, in case of a inflatable wall-shaped drop stitch member of about 2 m x 2 m, which may for instance have a thickness of about 0.1 m, such as for instance about 8 cm, about 10 cm or about 12 cm, the weight of the wall-shaped drop stitch member may be less than 20 kg, e.g. about 10-15 kg, such as about 12 kg.

By letting the inflatable wall-shaped drop stitch member, which may have rounded edges, define a jump wall surface, the jump wall, at least at and/or near its side defining said jump wall surface, can be free of sharp edges. Additionally or alternatively, although the inflatable wall-shaped drop stitch member may be far less resilient than a resilient foam padding of a padded jump wall in an indoor trampoline park and/or far less resilient than an inflatable wall of an inflatable castle inflated to about 30 mbar, said inflatable wall-shaped drop stitch member may still be far less rigid than a brick wall or concrete wall, such that the risk that a user gets hurt or injured can still be relatively low compared to using a brick wall or the like.

By providing the recreation jumping system with a support structure for supporting the inflatable wall-shaped drop stitch member and by making the inflatable wall-shaped drop stitch member releasably attachable to said support structure, the jump wall can be erected and/or dismantled relatively easily, at least partly. The inflatable wall-shaped drop stitch member, which may have a very low mass compared to a conventional wall, can relatively easily be removed, even in its inflated state, for instance in order to temporarily store it indoors when a predicted storm is anticipated. However, also deflating or inflating the inflatable wall-shaped drop stitch member may be done relatively fast. For example, it has been found that inflating a inflatable wall-shaped drop stitch member of about m x 2 m, which has a thickness of about 0.1 in, can be clone in just a few minutes by means of a dual action hand pump, i.e. a hand pump which produces airflow with upward as well as downward motion.

Advantageously, the support structure may form a backing structure which during use is located substantially behind the inflatable wall-shaped drop stitch member, i.e. at a side opposite to the jump wall surface that during use substantially faces towards the area above the bounce mat. Forces exerted onto the jump wall surface, for instance due to an impact of the user kicking or pushing against said jump wall surface, may then be transmitted to support structure, which in turn may be fixed relatively well with respect to the trampoline, for instance by fixing said support structure to a frame of the trampoline.

As the inflatable wall-shaped drop stitch member can form a relatively rigid board, in particular if it is inflated to about 6 to 16 bar, it will then not be necessary to support the inflatable wall-shaped drop stitch member over an entire rear surface thereof opposite to its jump wall surface.

For instance, the support structure, which for example may comprise a substantially tubular frame, may be arranged such that it during use only supports certain portions of the inflatable wall-shaped drop stitch member.

In embodiments, the support structure may for example comprise at least two posts, which may be interconnected by means of at least one bar such as for instance at least one crossbar and/or at least one arch-shaped bar, wherein the posts and/or the at least one bar, if any, may directly and/or indirectly support the inflatable wall-shaped drop stitch member, in particular at the rear side of said inflatable wall-shaped drop stitch member.

By providing a support structure, in particular a frame-shaped support structure, which preferably is arranged to only support one or more areas of the rear side of the inflatable wall-shaped drop stitch member, a support structure can be provided that is relatively open, i.e. which covers a relatively small area with respect to the area covered by the jump wall surface. As a result, when the inflatable wall-shaped drop stitch member is temporarily uninstalled, but the support structure is not uninstalled and remains in place, the view may for instance be unblocked to a relatively large extent in comparison to when the inflatable wall-shaped drop stitch member was still in place. Not only may the jumping system, once the inflatable wall-shaped drop stitch member is temporarily uninstalled, block the view to a smaller extent, but an other advantage may for instance be that the jumping system may then catch less wind, which can counteract problems in case of heavy storms.

In embodiments, the recreation jumping system may include a support structure for supporting the inflatable wall-shaped drop stitch member, wherein said support structure then can be mounted to a frame of the trampoline, preferably in a releasable manner. For example, the support structure and/or the trampoline frame may be provided with connectors to releasably connect or mount the support structure to the trampoline frame.

Advantageously, the support structure can be releasably mounted to the trampoline frame. Thereto, the trampoline frame and/or the support structure, especially posts of said support structure, may be provided with connectors to releasably connect or mount the support structure to the trampoline frame.

For instance to counteract that the jumping system could fall over, its trampoline, in particular when the inflatable wall-shaped drop stitch member is mounted thereto, for instance indirectly via a support structure directly mounted to a frame of the trampoline, the trampoline may be fixated to the ground and/or the trampoline may be a so-called sunken trampoline or in-ground trampoline. Additionally or alternatively, in case the trampoline is an elongated trampoline, the inflatable wall-shaped drop stitch may be disposed at a head end of the trampoline, as a result of which the center of gravity of the trampoline may lie relatively far away from the jump wall surface, such that the mass of the trampoline may counteract relatively well that the jumping system could fall over even when a user exerts a relatively high impact on the wall.

The present disclosure also relates to an inflatable wall-shaped drop stitch member.

Further, the present disclosure relates to a support structure arranged for supporting an inflatable wall-shaped drop stitch member.

Furthermore, the present disclosure relates to a trampoline frame provided with connectors arranged for firmly mounting a support structure, which is for supporting an inflatable wall-shaped drop stitch member, to said trampoline frame.

Moreover, the present disclosure also relates to a set of parts for assembling a jumping system.

Advantageous embodiments according to the present disclosure are described in the appended claims.

By way of non-limiting examples only, embodiments of the present disclosure will now be described with reference to the accompanying figures in which:

Fig. 1 shows a schematic perspective view of a first embodiment of a recreational jumping system according to an aspect of the present disclosure; and

Fig. 2 shows a second schematic perspective view of the recreational jumping system of Fig. 1.

It is noted that the figures show merely a preferred embodiment according to the present disclosure. In the figures, the same or similar reference signs or numbers refer to equal or corresponding parts.

Figure 1 shows a recreational jumping system 1, which comprises a trampoline 2 having a substantially horizontally extending bounce mat 20 or so-called trampoline bed 20. The recreational jumping system 1 further comprises a jump wall 3. During use the recreational jumping system 1, a user 7 can jump on the trampoline 2 and may additionally use the jump wall 3 to perform tricks, for instance by walking up against the jump wall 3 and/or taking off from said jump wall 3, for instance to perform backflips or other tricks.

The recreational jumping system 1 may be intended and/or arranged for home use, for instance in one’s garden. For example, the trampoline 2 can be an outdoor trampoline intended and/or arranged for outdoor use.

In embodiments, the trampoline 2 may be of a regular type and may have a bounce mat 20, or so-called trampoline bed 20, suspended above a ground surface by means of a trampoline frame substantially placed on the ground surface, which trampoline frame than has a height sufficient for allowing that the lowest point of the bounce mat 20 can still be above the ground surface when the bounce mat is deflecting to its maximum extent during use of the trampoline. The frame of such a regular type trampoline can comprise a suspension part to which the bounce mat is attached, in particular by means of multiple springs, more in particular coiled springs. The suspension part can be formed as a circular, rectangular or polygonal ring, for instance made of circular steel pipe. Such a ring-shaped suspension part can then be held sufficiently high above the ground surface by means of support legs which can be attached to said ring and which then can extend downwards up to the ground surface.

However, the trampoline 2 of the recreational jumping system 1 may advantageously be a sunken trampoline 2 or a so-called in-ground trampoline 2, which is a trampoline of a buried type. The trampoline 2 can then be sunken or buried into the ground, at least to a substantially extent. Like a regular type trampoline, such a sunken trampoline or so-called ground-sunk trampoline can also comprise a bounce mat 20, or so-called trampoline bed 20, which then can also be suspended by means of a frame 21. However, contrary to a regular trampoline, the bounce mat 20 of a buried or sunken trampoline is suspended at a relatively low height, for instance a height slightly above the ground surface level or even lower, in particular substantially at the ground surface level. A pit 22 can be dug out below the bounce mat 20 to enable sufficient deflection of the bounce mat 20 in a downward direction. It will be appreciated that said pit 22 can thus allow that at least parts of the bounce mat 20 move down to a level below the level of the ground surface when the bounce mat 20 deflects, for instance due to the impact of a user landing on said bounce mat. Like the frame of a regular type trampoline, also the frame of a sunken trampoline can for instance comprise a circular, rectangular or polygonal ring, for instance made of a circular steel pipe. The ring may be supported by means of one or more supports, which may for example be formed by relatively low support legs or may for example be integrated in the ring, which one or more supports may for instance be placed on the ground surface, just outside the pit or may for instance extend into the pit, and can then for instance rest on a recessed skirt or ledge enclosing a central main part of the pit 22.

The jump wall 3 has an inflatable wall-shaped drop stitch member 30 which defines a jump wall surface 31. Said inflatable wall-shaped drop stitch member 30 may be arranged to stand upright, e.g. at least partly by standing on its bottom side 38, which may extend substantially horizontally. As is the case in the here shown embodiment, the inflatable wall-shaped drop stitch member 30, or at least its jump wall surface 31, may have a substantially rectangular shape. However, in alternative embodiments, the inflatable wall-shaped drop stitch member 30 may have a different shape, e.g. not having substantially straight side edges and/or not having a substantially straight top edge.

The inflatable wall-shaped drop stitch member 30 can be made of and/or comprise drop stitch material. This material is for instance known in the field of SUPs, i.e. stand up paddle boarding or stand up paddle surfing, where it is used to make inflatable SUP boards, and can be considered to be substantially weatherproof.

The inflatable wall-shaped drop stitch member 30 may have a core element or a so-called drop stitch fabric matrix, which may include two support layers, in particular fabric support layers, more in particular woven fabric support layers, which for instance may be made of polyester or another plastic material or another suitable material. The two support layers may be connected to each other by means of thousands of filaments or threads, preferably substantially evenly spaced filaments or threads, in particular applied by means of drop stitch sewing and/or a drop stitch sewing machine. The thousands of filaments or threads connecting the two support layers have a predetermined length, which can limit the distance over which the two support layers can be offset from each other when the drop stitch member 30 is inflated. The filaments or threads may be made from polyester or another plastic or another suitable material, preferably being strong, durable and having very little stretch. On the outwardly facing sides of the two support layers an air-tight layer can be provided, for instance by means of a substantially air-tight coating, such as for instance a polyurethane coating, or by means of a substantially air-tight layer, such as a sheet of PVC (polyvinyl chloride) material, which then is thus supported by means of the support layers. At the other sides of inflatable wall-shaped drop stitch member 30, e.g. the top side, the lateral sides, and the bottom side 38, a substantially air-tight sidewall material may be provided, which is attached, for instance is glued and/or heat-welded, to the material of its front side 31 and rear side 32, respectively.

Thanks to the thousands of filaments or threads and the pressure inside the inflated wall-shaped drop stitch member 30, which may for instance be at least 5, 6, 7, 8 or 10 bar, it may be facilitated that an adult user can sit on top of the said inflatable wall-shaped drop stitch member 30 or may hang on said wall-shaped drop stitch member 30, without that said drop stitch member 30 bends, sags or snaps.

Although the drop stitch member 30 can for instance comprise a single air chamber, the drop stitch member 30 may alternatively comprise multiple air chambers, for example two or more air chambers being located behind each other when seen in a direction substantially transverse to the jump wall surface 31.

The inflatable wall-shaped drop stitch member 30 may be provided with one or more valves for enabling inflation. The inflatable wall-shaped drop stitch member 30 may be deflatable by means of the same valve or by means of another releasably closable opening. Additionally or alternatively, a pressure release valve may be provided for counteracting that the pressure in the inflatable wall-shaped drop stitch member 30 exceeds a predetermined threshold level, which may for instance lie at or above 8 bar, 10 bar, 12 bar, 15 bar, 17 bar or 20 bar.

The jump wall surface 31 may be formed as a substantially flat surface. It is noted that said surface may be a relatively rough surface 31, for instance in comparison to a rear side 32, for example in order to enable that the user can have relatively good grip on the jump wall surface 31, e.g. when walking up against the jump wall 3.

The jump wall surface 31 is located above the bounce mat 20, i.e. at least a part of a side of the drop stitch member 30 which defines said jump wall surface 31 extends above said bounce mat 20. Although the inflatable wall-shaped drop stitch member 30 may, as is the case in the here shown embodiment, may substantially extend above the bounce mat 20, the inflatable wall-shaped drop stitch member 30, which may be positioned adjacent to the trampoline 2, may in embodiments extend downward to such extent that it partly extends below the bounce mat 20. However, the part then located below the bounce mat 20 will then during use not define a jump wall surface 31.

The jump wall surface 31 faces substantially towards an area above said bounce mat 20. Preferably, when seen from above, substantially the entire bounce mat 20 may be located aside of the jump wall 3, at the side of the jump wall defining its jump wall surface 31, such as for instance is the case in the here shown embodiment. However, in alternative embodiments, the jump wall 3 may be disposed alternatively, and may for example be located above the bounce mat 20 such that the bounce mat can for instance extend at two opposite sides of said jump wall 3.

The jump wall surface 31 extends under an angle with the bounce mat 20. Preferably, the drop stitch member 30, or at least its side defining the jump wall surface 31, may extend substantially transverse to the ground surface and/or to the plane in which the bounce mat 20 substantially extends, and/or may extend substantially upright, in particular substantially vertically. However, in alternative embodiments, the jump wall surface 31 may be positioned differently for instance such that the jump wall surface 31 is formed as a sloping surface, for example to ease walking up against said wall surface.

Advantageously, the trampoline 2 can be an elongate or oblong trampoline, preferably a substantially rectangular trampoline 2, which may, when seen from above, have a substantially rectangular frame 21 and/or a substantially rectangular bounce mat 20. The inflatable wall-shaped drop stitch member 30 defining the jump wall surface 31 may then be located at a head end of said elongate trampoline 2. In case of a rectangular trampoline 2, the inflatable wall-shaped drop stitch member 30 may thus be located at a short side of said rectangular trampoline. As a result, the mass of the trampoline 2 may counteract relatively well that the jumping system 1 falls over even when a user exerts a relatively high impact on the jump wall 3.

The jump wall surface 31 may preferably extend substantially parallel with a side edge, in particular a short side edge, of the trampoline. Preferably, in particular in case the jump wall surface 31 extends substantially vertically, the jump wall surface 31 may be located outside of an area of the bounce mat left free by padding 23 that can cover springs that can suspense the bounce mat 20.

Additionally or alternatively, the jump wall surface 31, at least a lower portion of said jump wall surface 31 for instance in case the jump wall surface 31 slopes, may be located relatively close to the bounce mat 20. For example, a horizontal distance between the jump wall surface 31 and the area of the bounce mat 20 that can be used, and is thus for instance not covered by padding 23, may be less than 50 cm, preferably not more than 40 cm or not more than 30 cm, such as for instance at most 25 cm or at most 20 cm.

Advantageously, the jump wall surface 31, or at least a lower portion of said jump wall surface 31, may be located substantially above padding 23, which padding 23 may cover suspension springs, in particular coiled springs, suspending the bounce mat 20 in a trampoline frame 21. It may then be counteracted that a user unintentionally lands on the trampoline frame 21 or even outside the trampoline 2.

As can be seen best in Figure 2, which shows a different view of the recreational jumping system 1 of Figure 1, the recreational jumping system 1 may further comprise a support structure 4 for supporting or backing up the inflatable wall-shaped drop stitch member 30. Said support structure may be for backing up the drop stitch member 30 at a rear side of said member 30, i.e. at a side of the drop stitch member 30 opposite to the jump wall surface 31 that during use substantially faces towards the area above the bounce mat 20.

In embodiments, the support structure 4 can comprise a substantially tubular frame 40, for instance made of metal tubes, such as steel tubes or the like.

Additionally or alternatively, the support structure 4 can comprise at least two posts 41, 42. Said posts may be for supporting or backing up the wall-shaped drop stitch member 30. The posts 41, 42 may be interconnected to each other, in particular by means of a bar 43, such as for instance a crossbar or an arch-shaped bar 43, which bar may be integrally formed with the posts 41, 42.

Preferably, the support structure 4 can be mounted to the frame 21 ofthe trampoline 2. However, in alternative embodiments, the support structure 4 may be fixated in a different manner, for instance by mounting it to the ground or floor surface.

Advantageously, the support structure 4 can be mounted to the frame 21 of the trampoline 2 in a releasable manner. For example, said support structure 4 can be arranged for releasable connection to the trampoline frame 21. In particular, the support structure 4 may comprise at least two connectors 44 arranged for connecting to the frame 21, more in particular for cooperation with respective connectors 24 provided at the trampoline frame 21.

Additionally or alternatively, the trampoline frame 21 can be provided with one or more, preferably at least two, connectors 24. The connectors 24 of the frame 21 can be preferably be arranged for cooperation with a respective connector 44 of the support structure 4 for supporting the inflatable wall-shaped drop stitch member 30.

In het shown embodiment, the connectors 24 at the trampoline frame 21 are formed as sockets 24 for receivingly engaging corresponding plug-shaped connectors 44 of the support structure 4. Alternatively, the connectors 24 at the frame may be formed as plugs for receiving there around socket-like connectors of the support structure 4, which may be formed cavities formed by the hollow interior of a tubular part, in particular a tubular post 41, 42 of the support structure 4. It will be apparent, however, that one or more of the connectors of the trampoline frame and/or one or more of the connectors of the support structure may be of a different design.

In case of an oblong or elongate rectangular trampoline frame 21, the connectors 24 at the trampoline frame 21 may preferably be arranged for fixing the support structure 4 at a head end of the frame 21.

The inflatable wall-shaped drop stitch member 30 and/or the jump wall surface 31 defined by said member 30 may have a certain width W30 and/or height H30. For example, said width W30 may be at least 0.5 m, preferably at least 1 in, or at least 1.5 m, such as for instance about 2 m. Additionally or alternatively, said width W30 of the drop stitch member 30 and/or the jump wall surface 31 may correspond substantially with the width W2 of the trampoline 2 and/or with the width W20 of the trampoline bed 20, or at least its part not covered by padding 23.

Additionally or alternatively, said width W30 and/or the height H30 of the drop stitch member 30 and/or the jump wall surface 31 may be larger than the width and/or height, respectively, of the support structure 4. The drop stitch member 30 can then cover the support structure 4 over its entire width and/or height. Since the drop stitch member 30, even when inflated to for instance 10 bar, can still be more than the support structure 4, which for instance may be formed at least partly from steel or the like, this may increase the safety of the recreational jumping system 1.

The height H30 of the drop stitch member 30 and/or the jump wall surface 31 may for instance be at least 1 m, preferably at least 1.2 m or at least 1.5 m, such as for instance about 2 m or even more.

Moreover, the recreational jumping system 1, in particular its trampoline frame 21 and/or its support structure 4, may be arranged for releasably locking or fixating the support structure 4 mounted to the trampoline frame 21. For instance, one or more of the connectors 44 of the support structure and/or one or more of the connectors 24 of the frame may itself be arranged for releasably fixating or locking the temporal connection between the trampoline frame 21 and the support structure 4. Alternatively or additionally, a separate lock may be provided, which can counteract that the support structure 4 can unintentionally be disconnected from the trampoline frame 21, such that accidents due to a loosening support structure 4 can be counteracted.

It is noted that the inflatable wall-shaped drop stitch member 30 can preferably be releasably attached to said support structure 4. Thereto, the support structure 4 and/or the inflatable wall-shaped drop stitch member 30, especially at its rear side 32, can be provided with one or more fasteners 5 for releasably fastening the inflatable wall-shaped drop stitch member 30 to the support structure 4.

It is noted that the inflatable wall-shaped drop stitch member 30, which preferably has a substantially straight bottom edge, may at least partly stand on its bottom side 38. In particular, the bottom side 38 of the inflatable wall-shaped drop stitch member 30 may rest on top of the trampoline 2. In particular, it 38 may rest on top of a respective part of the trampoline frame 21, directly or indirectly, such as via an intermediately disposed padding located between an upper end of the trampoline frame 21 and the bottom side 38 of said drop stitch member 30.

However, in alternative embodiments the inflatable wall-shaped drop stitch member 30 may for instance be suspended completely, e.g. by means of one of more of the fasteners 5.

Advantageously, the releasable connection between the inflatable wall-shaped drop stitch member 30 and the support structure 4 may comprise, and/or may be substantially formed as, a band, strap, cord, rope or the like for fixing the drop stitch member 30 to the support structure 4. Such band or the like, which may be provided at the drop stitch member 30, in particular at its backside 32, may for instance may be tied up to a bar 40, 41 or post of the support structure 4 or to an other part, such as an eyelet or the like, provided at, on or in the support structure 4. In embodiments, the band or the like, that for example may be provided at the drop stitch member 30 or at the support structure 4, may for example form a preformed loop, that for instance can be attached to a connector, such as cooperating hook or the like, provided at the other one of the drop stitch member 30 and the support structure 4, or provided the same one of said drop stitch member 30 and the support structure 4. For example, such loop may be fixedly provided at the rear side 32 of the drop stitch member 30 and may, after being passed over or behind a respective part 41, 42, 43 of the support structure 4, be hooked or otherwise releasably fastened to the rear side 32 of said drop stitch member 30, which thereto for instance may be provided with a hook, eyelet or other fastener part.

It is noted that for the purpose of clarity and a concise description features are described herein as part of the same or separate embodiments, however, it will be appreciated that the scope of the present disclosure may include embodiments having combinations of all or some of the features described.

Further, it is noted that the invention is not restricted to the embodiments described herein. It will be understood that many variants are possible.

Such and other variants will be apparent for the person skilled in the art and are considered to lie within the scope of the invention as formulated in the following claims.
