NZ 788982 James & Wells ref: 309172 TRAMPOLINES, COMPONENTS THEREOF AND METHODS OF MANUFACTURE AND ASSEMBLY Statement of Corresponding ations This application is based on New Zealand Patent Application No. 775548, the entire contents of which are incorporated herein by reference.

Field of the Invention The present invention relates to trampolines, components thereof, and methods of manufacture and assembly.

Background to the ion Trampolines are rly used for various reasons including exercise, gymnastics, rehabilitation and entertainment. They can range in size from around 1 metre across to sizes exceeding 4 metres across.

Because of their large size, trampolines are commonly shipped in a disassembled state to reduce shipping costs. The dissembled trampoline comprises multiple components which are then led together by the purchaser.

It is desirable to be able to provide trampoline components which are simple and cost effective to manufacture while also allowing for easy ly by the purchaser into a useable line.

However, stock inventory of these components is an important consideration.

In general terms, a trampoline has a trampoline mat which is suspended from a support frame by resilient components. The support frame includes some form of structure (henceforth “a top rail”) that surrounds the line mat and legs which support the top rail above the . The top rail structure is commonly a circular or rectangular shape which is made of two or more segments which are connected together. In use, a person can stand or jump on the trampoline mat to deform the resilient ents suspending the trampoline mat. These resilient components provide a restorative force which opposes their deformation and assists the person to jump higher than they would ise be able.

There are two common types of trampolines. A standard, or sprung, trampoline uses a plurality of coiled metal s as the resilient components. Alternatively, a “spring-free” trampoline uses bendable rods, made from a composite material such as fibreglass, as the resilient elements. Either way, the resilient components suspend the mat and provide the elastic and resilient force needed to promote jumping.

Trampolines can be dangerous and there are several ways that people can be injured when using them.

Therefore, it is known to provide safety nets to e a r that stops people inadvertently falling James & Wells ref: 309172 off or being bounced or otherwise rebounded from the trampoline. These safety nets are commonly supported by net poles. The net poles attach to the support frame, either directly to the legs or to the top-rail. Common methods of connection include g and complex fastener arrangements which are tricky to assemble.

The trampoline components must be assembled er to provide the finished and complete trampoline. There are various proprietary s to assemble these components in the market and generally each manufacturer has its own such system. However, these systems each have issues which make them a less than optimal solution for a manufacturer and / or customer.

For example, many proprietary s e components, lly parts of the support frame and / or net poles, which are welded together. Welding has a number of disadvantages such as being a relatively expensive process and prone to e if done incorrectly. It can also introduce a weak point at which the frame could corrode or otherwise become structurally compromised. Additionally, any protective gs, such as painting or a powder coating, must be applied after the welding process.

That places restrictions on the order in which components can be manufactured. Furthermore, components manufactured using welding can also be difficult to package or ship due to their geometry.

Other known solutions are less desirable for the end user. For example, where components need to be joined using fasteners such as nuts and bolts, the purchaser must have the necessary tools, or the manufacturer must provide these with the trampoline further sing cost.

There are also potential safety ns with relying on the purchaser or end user to correctly assemble the trampoline. For e, failure to tighten a fastener sufficiently or to include important components such as washers can lead to the line being damaged or the fasteners inadvertently coming loose. Additionally, overtightening fasteners can cause failure such as stripping of a thread or damaging the components which are being . Thus, the structural integrity of the trampoline may be compromised.

According to another aspect of the technology, there is provided a trampoline which ses: a plurality of top rail segments that are connected to each other to form a top rail which defines a plane, a plurality of legs which in use support the top rail above the ground, James & Wells ref: 309172 wherein each of the plurality of legs has a respective first end that is connected to the top rail and a respective second end which is located distal to, and below, the plane, and further wherein at least one of the plurality of legs is orientated at an internal angle of less than 90 degrees to the plane.

Preferably, the line may se a trampoline mat. This trampoline mat may be constructed of a planar sheet of durable material. For example, the trampoline mat may comprise a fabric such as canvas or alternatively a polymer such as polypropylene. It may be advantageous for the line mat to comprise a mesh such as a woven mesh, as the mesh uction may increase the durability of the trampoline mat and / or better allow moisture to drain from the surface.

It should be understood that when the trampoline is led, the trampoline mat is suspended from the top rail. ably, at least one of the top rail and line mat may be substantially circular. Even more preferably, the top rail which has a shape that is substantially complementary to the shape of the trampoline mat. For example, the top rail may have a ring-like form and the trampoline mat may be ar.

In alternative embodiments, at least one of the top rail and trampoline mat may have a polygonal shape, i.e. the top rail and / or trampoline mat may be substantially square, rectangular, hexagonal or octagonal, or include a non-polygonal shape such as an oval, or a complex shape having any other le combination of polygonal and non-polygonal features.

It should be understood that reference herein to the trampoline and components f should be understood to encompass a kitset of parts ning same.

Preferably, the trampoline may include at least one resilient element. The resilient element may be at least one spring element in the form of an extension or tension spring(s). However, this should not be seen as limiting on the technology. F or example, the resilient element(s) may be torsion springs or flexible rods as should be known to those skilled in the art. In alternative embodiments of the technology, at least one resilient element may be the trampoline mat. For example, the trampoline mat may be constructed of a resiliently able material such as an elastomer.

The resilient element(s) of the present technology shall be referred to as spring(s). However, this should not be seen as limiting on the technology, and alternative resilient element(s) may be used within the scope of the technology.

James & Wells ref: 309172 Preferably, the spring(s) releasably attach to at least one of the trampoline mat and the top rail of the trampoline. For ce, each resilient t may have at least one fastener half which is configured to engage e.g. releasably engage, with a corresponding fastener half on the trampoline mat or top rail.

In the preferred embodiment, the spring(s) may include two fastener halves which engage with a corresponding fastener half on one of the trampoline mat and top rail.

For instance, the fastener half/halves on the spring may be a hook, loop or other structure. The er half on the trampoline mat may be an eyelet or D-ring while the fastener half on the top rail may be an aperture, e.g. a slot. However, it should be understood that the fastener half / halves may take other forms as should be known to those skilled in the art.

However, it is also envisaged that the spring(s) may be permanently ed to at least one of the trampoline mat and the top rail.

Preferably, the spring(s) may provide n to hold the ents of the top rail together e.g. the spring(s) and trampoline mat provide a tension force which pulls the top rail segments together and assists in preventing them disengaging from each other in use.

In a ularly preferred embodiment, the spring(s) may provide ntially all of the force holding the components of the top rail together. This should become clearer from the following description.

In preferred embodiments, the top rail segments may releasably connect together to form the top rail.

It is though, also envisaged that the top rail segments may not releasably connect together, e.g. they may be designed to be ently connected together.

In one ment, each top rail segment may have a male end and a female end. In these configurations, the male end may be shaped and / or dimensioned to be inserted into the female end of another top rail segment.

The male and female ends may have complementary shapes or profiles or be dimensioned so that the female end can receive the male end. For instance, the male end may have a circular cross-section while the female end may have a square cross-section. Alternatively, the male end and female end may have the same cross-sectional shape e.g. square or round, but have different ions to facilitate the male end being inserted into the female end.

However, it is also envisaged that the technology may use a separate connector to facilitate connecting any two top rail segments together to form the top rail. Accordingly, another aspect of the technology James & Wells ref: 309172 relates to a connector for use in g a top rail of a line, and a trampoline including a connector.

Preferably, each top rail segment may releasably connect with one or more connectors to form the top rail. It is though, also envisaged that the top rail segments may not releasably connect with a connector, e.g. they may be designed to be permanently connected to the connector(s).

In one ment, the connector(s) may include a first end configured to connect to a first top rail segment, and a second end ured to connect to a second top rail segment. Preferably the first end and / or second end of the connector can receive an end of the tive top rail segments. For example, the first end of the connector may be configured to receive a first end of a first top rail t, and the second end of the connector may be configured to receive a second end of a second top rail However, in alternative embodiments the first end and / or the second end of the connector may be dimensioned to insert into an end of a top rail segment.

In a yet further alternative embodiment, the tor may have a first end dimensioned to receive an end of a top rail segment and a second end dimensioned to insert into an end of another top rail segment. Preferably each of the top rail segments may be substantially identical, however this should not be seen as limiting on the scope of the technology.

The ends of the connector may have shapes complementary to the shape of the ends of the top rail segments. For instance, the male end of the top rail segment may have a circular cross-section while the female end of the connector may have a square cross-section. Alternatively, the male end and female ends may have the same cross-sectional shape, e.g. square or round, but have different dimensions to facilitate the male end being inserted into the female end.

In preferred embodiments, at least one of the first end and the second end of the connector may have a non-circular sectional shape. U se of non-circular sectional shapes may advantageously prevent or resist against rotation of the top rail segments relative to the connector in use.

The use of male and female ends should not be seen as limiting on the technology. For instance , in alternative embodiments the connector and top rail ts may connect to one another using an interference fit, threaded engagement, clamping, or any le fastener such as nuts and bolts, screws, rivets and welds.

Preferably, the connector may be constructed or otherwise formed of a durable material such as a metal, i.e. steel. However, this should not be seen as limiting on the technology and in some embodiments the James & Wells ref: 309172 connector may be constructed of a polymer such as glass filled nylon, opylene or PPS (polyphenylene sulphide) or alike.

Preferably, the connector may be constructed from substantially square box section of material. For example, the box n may be a steel box section having a wall thickness of between 2 mm and 5 mm, more preferably approximately 2.5 mm. ably this box section has an external width of between 25 mm and 52 mm, more preferably approximately 40 mm.

Preferably, the connector may have a length of between substantially 130 mm and ntially 170 mm, more preferably n 140 mm and 160 mm, more preferably substantially 150 mm.

It should be understood that the recited dimensions for the connector may be dependent on the dimensions of the top rail and / or overall trampoline size, and variances from these will be readily envisaged to those skilled in the art.

Preferably, the connector may include one or more protuberances. These protuberances may be formed by creating an indentation in one or more faces of the connector so as to form a protuberance on an opposing side of said face. However, in ative embodiments, the protuberance may be formed by ing a separate component. For e, a lug or the like may be added using welding or adhering techniques or by using a fastener.

Preferably, the protuberance may be configured to engage with a complementary channel on a top rail segment. This arrangement may facilitate easier assembly of the trampoline, e.g. by ensuring that the connector and top rail are in alignment and are connected in the correct ation.

Preferably, the top rail segments may be held in engagement with the connectors under tension. For example, by using the tension provided by the trampoline mat and / or spring(s). However, in alternative embodiments, these components may be held in engagement using fasteners or any other suitable connection mechanism.

Preferably, the aperture in the top rail is non-circular; for example, the aperture may have a rectangular or oval shaped profile. Use of non-circular apertures may assist in preventing rotation of ents such as legs or net poles which may be inserted into the aperture. In alternative embodiments the aperture(s) may be circular which could be more cost effective to manufacture than non-circular apertures.

Preferably, the aperture is configured to receive an end of a leg, for example the leg may be inserted into the aperture. In ative embodiments, the connector may instead include one or more James & Wells ref: 309172 components which facilitate connection of the leg to the top rail. For e, the components may include a protrusion, clamp or other suitable fastening arrangement.

In some embodiments at least one leg may extend through two apertures in the top rail. For example, the leg may pass through two apertures in the top rail, such that at least a portion of the leg extends above a top surface of the top rail. Preferably in these embodiments, the top rail has a top or upper surface and a bottom or lower surface and the apertures are provided to the respective surfaces.

Positioning a portion of the leg above the top surface of the top rail may facilitate the leg being locked to the top rail, for example by using a locking mechanism such as that bed in more detail below.

Preferably, the portion of the leg which extends beyond the top rail is configured to connect to a net pole. For e, an end of the leg may be ured to connect to a net pole, for example by having mating halves, such as male and female ends as described herein. This may advantageously allow the net pole of the trampoline to connect ly to a / the leg, while still being supported.

Preferably, the leg(s) may be configured to support the top rail (and thereby also the trampoline mat) above the ground. The leg(s) can bear down on the ground over which the trampoline is assembled and used. This may facilitate the trampoline being used without the trampoline mat touching the ground in Preferably, the legs may include feet. The feet in use can bear down on the ground to increase the contact e to the ground and provide additional stability to the line.

In addition, the feet may connect to two or more legs which are spaced around the perimeter of the top rail. The use of feet which join one or more spaced apart legs may provide additional bracing to the trampoline structure.

However, in alternative embodiments, feet may not be used.

Preferably, the leg(s) may include a bearing surface on which the top rail may bear down in use. This bearing surface may be in the form of a shoulder formed by compression or flaring of a portion of the leg. In alternative embodiments, the bearing e may be ed by a , or any other le protrusion.

Preferably, the leg(s) may be angled with respect to a plane defined by the top rail or mat. For example, the leg(s) may be orientated at an angle of between 5 and 15 degrees to that plane. More preferably the leg(s) may be orientated at an angle of approximately 10 degrees to the plane defined by the top rail or mat.

James & Wells ref: 309172 Preferably, the legs may be angled to locate an end of the leg(s) distal to the top rail within the perimeter of the trampoline as defined by the top rail. In alternative embodiments, the leg(s) may be orientated substantially ally so that the distal end of the leg(s) are located substantially below and inline with the perimeter of the trampoline.

Preferably the top rail may have a top or upper e and a bottom or lower surface. Preferably the bottom surface of the rail may face towards the ground when the trampoline is in use, while the top surface of the top rail may face upwardly (away from the ground) when the line is in use. ably the aperture in the top rail may be at least in the bottom surface of the top rail.

It may further be advantageous for the aperture in the bottom surface of the top rail to bear upon the g surface of the leg in use.

In embodiments where the top rail is formed from one or more hollow elongate components, these components may be extruded. I t may be advantageous for the aperture to be formed directly in the bottom surface of said hollow elongate components. In other words, it may be advantageous for the aperture to be formed ly in the top rail t(s) and / or connector(s), as opposed to having the aperture provided by a member which is attached to, and extends from, the top rail t(s) and / or connector(s). By forming the aperture directly in the hollow elongate components, it may be possible to reduce the manufacturing costs of attaching a separate or additional member to the top rail segment(s) and / or connector(s) to facilitate connecting the leg(s) to the top rail.

Preferably, the trampoline may comprise one or more net poles. These net poles may be configured to support a safety net in use.

Preferably, the net pole(s) may include a surface configured to, in use, bear down on a corresponding bearing surface on a leg. Preferably the bearing surface on the leg(s) is provided in an outer surface of the leg. For example, the bearing surface may be in the form of a shoulder formed by compression or flaring of the net pole. In alternative embodiments, the ering member may be provided by a flange, clamp or any other suitable protrusion.

Preferably, the trampoline may include at least one locking mechanism that is configured to secure at least two ents together.

In one embodiment, the locking mechanism may attach at least one top rail t to a connector.

Alternatively, or in on, the locking mechanism may connect a net pole and a leg to at least one of each other, the top rail or a connector.

James & Wells ref: 309172 In some embodiments, the locking mechanism may be configured to secure the net pole both axially and rotationally relative to the leg.

Alternatively, the locking mechanism could connect the net pole to other components of the trampoline, such as the leg and foot, or top rail segments.

In a particularly preferred ment, the locking mechanism may preferably be a spring-biased locking member, which is mounted in or to the net pole and / or leg. However, alternative locking mechanisms, such as screw fasteners, pins and clamps may be used.

Preferably, the components of the trampoline may be ured to releasably t together. This may enable the trampoline to be packed away or orted more . Preferably this releasable connection may be achieved t the use of tools such as hammers, rs or screwdrivers. For example, the components of the trampoline may be dimensioned such that they are able to releasably engage with neighbouring components using a tight slide fit tion. For e, the top rail segments may connect to one another, or to one or more connectors using a male to female connection.

Similarly, a tight slide fit connection may be used on other components of the invention such as the leg(s) and top rail, leg(s) and feet, net poles and legs etc. It should be appreciated that other methods of connection may be used as should be known to those skilled in the art.

In some embodiments, one or more components of the trampoline may be held together using a locking mechanism as described herein. In alternative embodiments, components of the trampoline may be held together by a friction fit or interference tight slide/wedge fit. In addition, tension from the spring(s) may assist to hold together the components once they fully engage each other. For example, the leg(s) may be held in engagement with the top rail using a tight slide/wedge fit, a friction fit, or atively due to biasing of these components towards each other due to gravity.

Preferably, a trampoline and components f according to the technology, may be constructed using methods other than welding. For example, the manufacturing processes used may include extrusion, bending drilling, punching, stamping and coating. By removing welding from the manufacturing processes, the manufacturing cost and / or complexity may be reduced.

Preferably, one or more components of the present technology may include a protective or aesthetic coating, e.g. they may be powder coated. However alternative coatings may be used such as galvanising, oplating, passivating, painting, plastic g, or chemically coated, such as using the AlodineTM process of Henkel e Technologies.

James & Wells ref: 309172 Preferably a method of assembling the trampoline may comprise one or more of the following steps in any order: a) Connecting the plurality/series of top rail segments to form the closed top rail shape; b) Inserting at least one leg into a ponding aperture in the top rail; c) ng a locking mechanism to prevent removal of the leg(s) from the top rail; d) Attaching feet to one or more of the legs; e) Attaching a net pole to at least one of the legs and the top rail; f) Attaching a safety net to one or more of the net poles; g) Attaching padding to the trampoline; h) Attaching a ladder to the top rail of the trampoline; i) Attaching the springs and the mat.

Advantages of the present logy should be apparent from the present disclosure, gh these may include a trampoline and components thereof which are: • easier to assemble – for example, by providing a trampoline which has fewer components, less complex components or components which lend themselves to a simpler assembly process; • sturdier – for example, by providing components which are able to engage with each other more tightly; • more reliable – for example, by removing the ial of failure due to welded components or over/under tightened fasteners; • more cost-effective to manufacture – for e, by removing welding processes, and allowing the protective coating to be applied at any part of the process; • more cost-effective to ship – for e, by ing components which have less complex geometry; and / or • more aesthetically pleasing – for example, by removing unsightly welds and ers.

Further aspects of the technology, which should be considered in all its novel aspects, will become apparent to those skilled in the art upon reading of the following ption which provides at least one example of a practical application of the technology.

Detailed Description of red Embodiment(s) Referring first to Figure 1A which shows a partially led trampoline (generally indicated by 100) according to an aspect of the present technology.

As shown, the trampoline (100) includes a trampoline mat (102) and a support frame indicated generally as (105). The support frame comprises, in general, a top rail (104) and legs (108). The trampoline mat (102) provides a surface for a user to bounce or exercise on. The trampoline mat (102) is constructed of a flexible material so that it can be easily folded and transported. The flexible material may be or e a fabric such as canvas or a polymer such as woven polypropylene. These examples however should not be seen as limiting on the technology and any other suitable material may be used. In the preferred embodiment the flexible material is ntially non-elastic, however this should also not be seen as limiting as it could also have a degree of elasticity.

James & Wells ref: 309172 The trampoline mat (102) is attached to the top rail (104) by at least one resilient element, e.g. one or more extension or coil springs, indicated as (106). The springs (106) shown in Figure 1A and 1B are positioned around the circumference of the line mat (102) and extend away from the edge of the trampoline mat (102), connecting it to the top rail (104) of the support frame (105).

Alternative resilient elements may also be used; for example torsion springs may be used or resiliently flexible rods as should be known by one skilled in the art. Attachment of the mat (102) to the t frame (105) will be discussed in more detail below.

It can be seen in Figure 1 that the top rail (104) and mat (102) have a circular shape in plan view. r, this should not be seen as limiting on the technology and other shapes for the top rail (104) and trampoline mats (102) may be used. For example, the top rail (104) and / or the trampoline mat (102) may have a ntially polygonal shape such as a square, rectangle, hexagon or octagon, or a non-polygonal shape such as an oval.

The top rail (104) is supported by the legs (108). In the embodiment of Figure 1A, the trampoline (100) has 8 legs (108), arranged in opposing pairs. However , it is also possible that other numbers of legs (108) could be provided e.g. in a larger or smaller diameter trampoline (100).

The legs (108) ensure that the trampoline mat (102) is raised above the ground over which it is positioned. However, this should not be seen as limiting on the logy, and in some configurations, such as in-ground trampolines, the top rail (104) instead may be mounted to a support structure which does not have legs.

In the embodiment of Figure 1A, the trampoline also includes feet (110). In the illustrated embodiment, the feet (110) each interconnect a pair of radially adjacent legs (108). The feet (110) may provide improved ity to the trampoline (100) by sing the surface area of the support frame (105) which is in contact with the ground. In addition, having feet (110) interconnecting radially nt legs (108) may effectively brace and r stabilise the legs (108) and the trampoline (100).

It should be appreciated that alternative feet (110) configurations may be used within the spirit and scope of the technology. For example, instead of linking adjacent pairs of legs (108) together, the feet (110) may instead link more than two legs, such as three or four legs, or alternatively all of the legs may be linked together.

Figure 1B shows a close-up view of detail ‘H’ in Figure 1A and illustrates one way to attach the top rail (104) to the trampoline mat (102) using the springs (106). In this embodiment, each spring (106) includes James & Wells ref: 309172 a first fastener half (107A) and a second fastener half (107B). In the illustrated embodiment, each fastener half (107A, 107B) is a hook formed by ation of an end of the spring (106).

The first fastener half (107A) can releasably engage a complementary er half (104A) on one of the top rail segments (118), e.g. a slot or hole in the top rail segment (118). The second fastener half (107B) can releasably engage a complementary fastener half provided on the trampoline mat (102), e.g. a D- ring (not shown in the Figures).

In some ments of the logy, the trampoline (100) also includes net poles (112). The net poles (112) may be curved as shown in Figure 1A, substantially ht as shown in Figure 1C or be configured with both a curved section and a ht section. The net poles (112) are configured to, in use, support a safety net (114) as is shown in Figure 1C.

The safety net (114) is shown in Figure 1C as a transparent component for clarity purposes. However, the safety net (114) is typically a durable see-through fabric or mesh which acts as a barrier to prevent users falling from, or ng off, the trampoline (100).

The safety net (114) may also be attached to an upper support member (not shown in the Figure) which is connected to and supported by the net poles (112). For example, the upper support member may be a ring-like structure which is supported by upper ends of the net poles (112). In an alternative embodiment the upper support member may include a plurality of straight sections which connect n an upper end of radially adjacent net poles (112).

Also shown in Figure 1C, the line (100) es pads (116) which cover the springs (106). These pads (116) may improve the safety of the trampoline (100) by reducing or otherwise minimising exposure to the springs (106) of the trampoline. For example, it may be advantageous to limit exposure to the springs (106) or falling between the springs (106) to reduce the likelihood that a person’s hands or skin is caught in a spring (106) during use.

Referring now to Figure 1D showing an exploded view of a section of the trampoline (100) according to the embodiment of Figure 1A. In this embodiment the top rail (104) is formed from a plurality of top rail segments (118). Each top rail segment (118) includes a first end (118A) and a second end (118B). These respectively engage with connectors (122).

Figure 1D also shows that each net pole (112) has a two-part construction having a first net pole segment (120A) and a second net pole segment (120B). The first and second net pole ts (120A, 120B) are designed to releasably connect with one another to provide the net poles (112). This met hod of James & Wells ref: 309172 uction may also be used with other components of the present technology. For example, the legs (108) and / or feet (110) may also be provided by one or more leg or foot segments.

Referring now to Figures 2A to 2F which show one approach to connecting top rail segments (118) of a trampoline (200) according to the present logy. In the embodiment of Figures 2A to 2F a connector (122) ts two of the top rail segments (118) to each other. This forms a portion of the top rail (104), and once all top rail top rail segments (118) are connected together the entire top rail (104) is formed.

In on, each tor (122) can connect at least one of a leg (108) and a net pole (112) to the top rail (104).

In some embodiments of the technology not shown here, the connector (122) may not be used. In these embodiments at least one of the net poles (112) and the legs (108) may connect separately of each other to the top rail segments (118).

The connector (122) includes at least one aperture (220) configured to receive a leg (108) of the trampoline (200). The aperture (220) is preferably formed in a lower surface of the connector (220) which, when the trampoline (100) is assembled, completely or partially faces towards the ground on which the trampoline (100) is assembled.

The tor (122) of Figures 2A to 2F also es an upper aperture (221) on an upper surface. This allows the leg (108) to at least partially pass through both apertures (220, 221). This arrangement however should not be seen as limiting, for example in embodiments which do not include net poles (112), or where the net poles (112) are instead attached to a side of the leg (108), the tor (122) may not include upper aperture (221).

In the embodiment of s 2A to 2F, the aperture(s) (220, 221) are substantially ar. It should be appreciated that it may be advantageous for the aperture(s) to have a complementary shape to the leg (108) and/or net pole (112) to ensure a tight fit. It should also be appreciated that in alternative embodiments the apertures (220, 221) may be non-circular, e.g. oval or rectangle such as a square.

Providing non-circular aperture(s) may limit or prevent the leg (108) and / or net pole (112) from rotating relative to the connector (122).

As best seen in Figures 2B and 2C, the leg (108) es a bearing surface (222) in the form of a shoulder.

In use, the connector (122) bears down upon the bearing surface (222) to limit the distance that the leg (108) can travel through the aperture(s) (220, 221) in the connector (122). In the embodiment shown, the bearing surface (222) is constructed by reducing of a portion of the leg (108) at or towards an end James & Wells ref: 309172 of the leg (108). However, this should not be seen as limiting on the technology, and alternative methods of providing a bearing surface (222) as should be known to those skilled in the art are envisaged. For e, suitable methods include attaching a flange or other suitable ding member to the leg (108), bly attaching a fastener to the leg (108), a ng mechanism which attaches to the leg (108), or flaring a portion of the leg (108).

The bearing surface (222) is preferably provided on an outer surface of the leg (108). This may advantageously allow the end of the leg (108) to pass through the aperture(s) (220, 221).

As shown in Figure 2C the ends (118A, 118B) of the top rail segments (118) end include a vely short region (223) which enables the ends (118A, 118B) to be inserted into the connector (122). However, it should be iated that alternative methods of connecting the top rail segments (118) to the connector (122) may be ed within the spirit and scope of the present technology. For example, connection of the top rail segments (118) with the connector (122) may be achieved using any of the methods described above in relation to the connection of the leg (108) with the connector (122).

In addition, as shown in Figure 2C the top surfaces of the ends of the top rail segments (118) include at least one recessed channel (224) which can receive a corresponding protuberance (226) ed to an interior e on the connector (122). The protuberance (226) and channels (224) co-operate to assist with alignment of the top rail segments (118) with the connector (122) or to prevent rotation of the components relative to each other, and limit the internal travel of top rail segment 118 into 122.

Referring now to Figures 3A to 3D which rate additional features of the connector (122). It can be seen that the embodiment includes an aperture (221) in the upper (227) surface and an aperture (220) in the lower surface (229) respectively of the connector (122). The apertures (220, 221) allow for ion of the leg (108) and net pole (112) (as described in more detail below).

In one embodiment, the protuberance (226) is formed as an indentation in the upper surface (227) of the connector (122). H owever, alternatives embodiment may include a protuberance (226) which is formed by any other process known to those skilled in the art. For example, the protuberance (226) may be a separate component which is attached to the connector by way of welding, fastening, adhesives or otherwise engaging with an aperture in the connector (122).

Similarly, while the channel (224) is illustrated as an indentation in the top rail segments (118) as per the ment of Figure 2C, alternatives configurations for the channel, such as slots, may be used without departing from the scope of the technology. In a yet further alternative, a channel may instead be provided in the tor (122) and a protuberance can be provided on the top rail segment(s) (118).

James & Wells ref: 309172 In use, for example as shown in Figure 2C, an end (108A) of the leg (108) is inserted through the apertures (220, 221) in the connector (122). An end (112A) of the net pole (112) is then inserted into the end (108A) of the leg (108). The net pole (112) is preferably held at the appropriate position within the leg (108) by way of a bearing surface (228), e.g. a shoulder, formed in the net pole (112). It should be appreciated that the bearing surface (228) of the net pole (112) may be formed using any of the methods bed in relation to the bearing surface (222) of the leg (108).

A locking ism may be used to secure the leg (108) and net pole (112) to each other. In the illustrated embodiment of Figures 2D and 5A the g mechanism is provided by a locking member (230) which can be optionally biased by a spring (233). One advantage of using a spring biased locking mechanism is that it may allow the trampoline to be assembled without the use of tools. However, this should not be seen as limiting and any suitable locking mechanism (230) may be used. For example, the locking mechanism may be a fastener such as a nut and bolt, a clamp or a pin.

The locking member (230) can take any form such as an elongate member, or a relatively small, complete or partial sphere shape to provide a detent.

As best seen in Figure 2C, the locking member (230) is configured to engage with a locking aperture (231B) in the net pole (112) and a locking aperture (231A) in the leg (108). The g mechanism may limit or t s movement of the connector (122) on the leg (108) and net pole (112). It should be appreciated that the above example should not be seen as limiting on the technology, and in alternative embodiments of the technology, the net pole (112) may be connected to the leg (108) without the use of a locking mechanism.

It should be appreciated that in embodiments where locking mechanisms are not used, the net poles (112) may be able to rotate relative to the leg. This can be rable, particularly where curved net poles (112) are used, as the curvature of the net poles (112) relative to the trampoline (100) could not be controlled. One technique for preventing this rotation is to use non-circular leg ends (108A) and net pole ends (112A).

Referring now back to Figure 2D, which shows a l cross-section of the net pole (112), leg (108), connector (122) and the locking mechanism. In this view it can be seen that the g mechanism is mounted inside the net pole (112). This process may be done during manufacture of the individual components such that the assembly process for the er is as simple as possible.

The above examples illustrate an embodiment n the end (112A) of net pole (112) is positioned within the leg (108) in use. It should however be appreciated that this arrangement should not be seen James & Wells ref: 309172 as limiting on the technology. For example, in an ative embodiment, the end (108A) of leg (108) may be inserted into the end (112A) of net pole (112) and secured in place by a corresponding g mechanism. Alternatively, the leg (108) and net pole (112) may otherwise connect with each other for e by using corresponding protuberances and ls which interlock with one another.

Figures 2E and 2F illustrate exemplary embodiments of how the springs (106) can be positioned ve to the connector (122). The springs (106) can be close to the ends of the connector (122), which can provide a number of advantages. For ce, this may assist in ing a substantially equal tension around the perimeter of the top rail (104). In addition, it may assist to pull the top rail segments (118) into engagement with the connector (122). It should be appreciated that in alternative embodiments of the technology, the springs (106) may be configured to engage with the connector (122) and / or the top rail segments (118). Engaging the springs (106) with both the top rail segments (118) and connector (122) may further ensure that the top rail segments (118) are unable to disengage from the connector (122) until the springs (106) are removed.

It may be advantageous for the connector (122) to be constructed of a durable material such as a metal, however this should not be seen as limiting on the technology and polymers may also be used. In the preferred embodiment the connector (122) is constructed of a steel extrusion such as a box-section.

This box-section preferably measures substantially 150mm long +/- 20mm and has an external width of substantially 40mm +/- 2mm with a 2.5mm +/- 0.5mm wall thickness. However, these dimensions are ed by way of e only and should not be seen as limiting on the technology.

In the preferred embodiment of the technology, one or more of the trampoline components may be provided with a protective g and / or cosmetic coating to improve the appearance and / or corrosion resistance. For example, the protective and / or cosmetic coatings may include one or more of galvanising, electroplating, ation, painting, powder coating, plastic coating, or chemical coating such as a chromate conversion coating, as occurs in the AlodineTM process of Henkel Surface Technologies.

It should be appreciated that in some embodiments it may be advantageous to combine the technology bed herein in certain regions of a trampoline while using other ment mechanisms such as welding in other regions. F or example, one embodiment of the technology may use a connector as described herein which attaches the top rail (104) to the legs (108) of the trampoline (100). This embodiment may still include one or more welded connections, for example to attach the net poles (112) of the trampoline directly to the legs (108) or the top rail (104).

James & Wells ref: 309172 Furthermore, while the present logy provides examples of how the various components and segments of the trampoline may be secured together using any suitable methods known to those skilled in the art. For example, one or more of the components may be secured using: fasteners such as nuts, bolts and , threaded connections, interference or friction fits, or locking pins or spring biased g mechanisms.

Referring now to Figure 4 which shows an exploded view of an alternative embodiment of the t logy. In this embodiment the leg (108) of the trampoline is configured to be inserted through the apertures (220, 221) of the connector (122). Optionally a straight net pole (112) may engage with the end (108A) of the leg (108) as bed in relation to the previous embodiments. However, in this embodiment it is envisaged that a locking mechanism is not required to secure the straight net pole (112) to the leg (108) and/or prevent the leg (108) from coming loose from the connector (122).

For e, it may be sufficient to rely on a friction or interference fit between the connector (122) and leg (108) or n the leg (108) and straight net pole (112). This friction or interference fit, er with gravity and/or spring tension, s the respective components of the trampoline together.

It may also be advantageous to provide the net pole (112) and or leg (108) with a gradual taper. Use of a gradual taper may advantageously increase the engagement force between the net pole (112) and leg (108) or leg (108) and connector (122) due to the aforementioned friction or interference fit.

Providing a trampoline (100, 200) and components thereof that are able to be assembled without locking may have a number of advantages, including: • A lower manufacture cost for the components; and • A faster, simpler assembly for the customer.

Referring now to Figures 5A to 5C which show yet a further alternative embodiment of the technology which does not require the separate connector (122) of the us embodiments described. s 5A and 5B are exploded and assembled views of section “C” shown in Figure 2C.In these Figures, like references refer to like components previously described. In this embodiment, it can be seen that the leg (108) is configured to connect directly to the top rail segments (518). This construction may advantageously reduce the total manufacturing costs, reduce weight and shipping costs, and provide a simpler method of manufacture.

In this embodiment the top rail ts (518) include a male tapered end portion (502) which in use is inserted into an aperture (not fully illustrated) in an end (518A) of a female open-ended portion of the James & Wells ref: 309172 adjacent top rail t (518). This method of connection however should not be seen as limiting on the invention, and ative methods of connection may be used without departing from the spirit and scope of the technology. For example, the top rail segments (518) may instead connect using a threaded engagement, friction or interference fit, clamp or any other fastener arrangement known in the art.

It should be tood that the top rail segments (518) may be held together using any of the methods described in relation to the previous embodiments. For example, the top rail segments (518) may be held together using the tension of the springs (106) together with the trampoline mat (102).

In use, the end (108A) of leg (108) is inserted through an aperture (520, 521) in a lower and upper e of the top rail segment (518). The end (108A) may also extend through an aperture (521) in an upper surface of the top rail segment (518). An optional net pole (112) may then be ed into the end (108A) and optionally secured in place, along with the leg (108) using a locking ism (230) that engages with apertures 231A and 231B. Alternatively, where a net pole (112) is not used the leg (108) may simply be d relative to the top rail segment (518) using the locking mechanism (230) and spring (233). ing now to Figure 6 which shows a yet further embodiment of the logy, wherein the components of the trampoline as assembled without the use of a locking mechanism (230) or connector (122). Removal of the locking ism may be achieved using any of the methods described in relation to Figure 4, while a connector (122) may not be required due to use of the approaches described in relation to Figures 5A to 5C.

It may be advantageous to provide a trampoline and components thereof which can be assembled t the use of locking mechanism or connectors (122). For example, removal of locking mechanisms and connectors may advantageously reduce the manufacturing cost of the trampoline and/or provide trampoline components which are easier to assemble.

In the example illustrated in Figures 1D and 2A, the net pole (112) is constructed of at least two net pole segments (120A, 120B) respectively. Use of two or more net pole segments (120A, 120B) to form the net pole (112) may advantageously allow for a compact packaging. However, this should not be seen as limiting on the technology. s 9 to 11 illustrate prior art methods of attaching a net pole (1090) to a leg (1092) of a trampoline.

In the embodiment of Figure 9 a net pole connector (1094) is welded to a side of the leg (1092) in order to receive the net pole (1090). It can also be seen that a bracing bracket (1096) has also been welded James & Wells ref: 309172 between the net pole connector (1094) and the leg (1092) in order to provide the necessary support to the welded connection in use.

The result is that the prior art legs are x and costly to manufacture. In contrast, the present technology reduces costs of manufacture and fies manufacturing requirements by solving problems in the prior art.

Additionally, the leg of Figure 9 is r to ship and more awkward to , which may complicate the assembly process. Furthermore, welding is a relatively expensive process which requires expertise to be performed correctly, and as previously mentioned, welding complicates the manufacturing order as any tive coatings must be applied post-weld.

Figure 10 provides an alternative method of attaching a net pole (1190) to a leg (1192) using a series of spacers (1196) and fasteners (1198). This approach has a number of disadvantages over the present technology including that the: • Trampoline is more complex and time consuming to assemble; • Fasteners introduce a potential failure point in the trampoline, as they may work loose during operation; • Fasteners and s introduce additional cost to the trampoline; and • That the fasteners may become damaged during installation if overtightened.

A common feature of the prior art leg arrangements and components in Figures 9 and 10 is that a connector (1095) is formed with a top portion (1290) which is welded to a lower portion (1292), as best seen in Figure 11.

The top portion (1290) is configured to t two top rail segments together, while the lower portion (1292) receives a leg (1092, 1192). However, the ement to weld the top portion (1290) and the lower n (1292) to each other has a number of disadvantages compared to the present technology, including that the prior art connector (1095): • Is more expensive to manufacture; • Is bulkier than that present technology; • Does not accommodate a net pole (1090, 1190); and • Must be welded prior to applying a protective coating.

Alternate net pole and leg connections James & Wells ref: 309172 Referring now to Figures 7A to 7C, in which like references refer to like components previously described, these show an alternative arrangement to connect at least one of the net poles (112) and the legs (108) to the top rail (104). In the embodiment of Figs 7A to 7C, the net poles (112) and legs (108) are secured to the connector (122). This arrangement may prevent rotation of the legs (108) and / or the net poles (112). This construction may be particularly beneficial in embodiments where the legs (108) of the trampoline (100) are not linked together by feet (110), in which case they may be able to rotate e.g. relative to one another and / or the top rail (104).

Preventing rotation of the net poles (112) relative to the top rail (104) can simplify the overall construction of the trampoline (100) and the respective components. For instance, if the net poles (112) could rotate relative to the top rail (104) would make it more difficult to attach a net to the net poles (114) or hinder the net poles (114) holding the net in a desired position. Other arrangements to prevent net pole (114) rotation include a separate ring-like structure.

Figure 7A illustrates one method of preventing on of the net poles (112). As shown, the locking member (230) is positioned and orientated to align with and extend into an re (702) in the connector (122). In this way the g member (230) links the net poles (112), legs (108) and connector (122) together to substantially prevent rotation relative to one another.

Figure 7B es an exploded view of the embodiment of Figure 7A. In this view it can be seen that the locking member (230) is attached to the interior of the net pole (112). In use, an end (108A) of the leg (108) is inserted through the apertures (220, 221) in the connector (122). The end (112A) of the net pole (112) is then inserted into an re (unnumbered) in the end (108A) of the leg (108). The locking member (230) at least partially inserted into the locking aperture (231A) in the leg (108) and the aperture (702) in the connector (122).

The top rail segments (118) are each configured to engage with the connector (122) by slidably inserting the respective ends (118A, 118B) into the ends of the connector (as described elsewhere herein).

Figure 7C provides a close-up view of the connector (122). From this view it can be seen that the aperture (702) is shown as an elongated slot. This shape may advantageously assist with ent of the locking member (230) relative to the aperture (702). This r should not be seen as limiting on the scope of the technology, and in other examples of the technology, the aperture (702) may be substantially circular or any other le shape such as rectangular.

Orientation of legs to top rail James & Wells ref: 309172 Figure 8A shows a further e of the present technology in which the leg (108) is orientated at an angle relative to the horizontal plane of the mat. As a result, the end (108B) of the leg (180) distal to the top rail (104) is located within the perimeter of the trampoline as defined by the top rail (104). This approach may provide a number of advantages, including one or more of the following: • improving the stability of the trampoline (100) compared to trampolines (100) that have vertically orientated legs; • facilitating uction of trampolines (100) of different diameter while improving foot space and clearance around the trampoline; • improving the tics of the trampoline (100).

Figure 8B shows a close-up of section “C” shown in Figure 8A. As shown, the connector (122) is configured so that a lower surface (229) in which the aperture (220) is located is inclined with respect to a horizontal axis or plane, e.g. a plane defined by the top rail (104) or the trampoline mat.

In the illustrated embodiment, connector (122) has a square cross section, and so the entire connector (122) is “twisted” to orientate the bottom surface(229) at an angle relative to the ntal axis or plane. However, it is also envisaged that the connector (112) may have a non-square cross n, e.g. a elogram or trapezoidal cross section allowing the lower surface (229) to be inclined to the horizontal.

The angle (802) is preferably between 5 and 15 degrees from vertical, or more ably approximately degrees from vertical.

Alternatively, the angle may be defined relative to a substantially ntal plane on which the top rail (104) lies in use. For example , the angle (802) may be imately 10 degrees from the horizontal plane of the top rail (104).

Figure 8C shows a close-up cross-sectional view of section “B” shown in Figure 8A. As shown, the net pole segments (120A, 120B) may be ted using a locking mechanism as described herein. Other methods of attaching net pole segments (120A, 120B) may be used without departing from the scope of the technology, such as ers or an interference fit.

Figure 8D shows one example of a top rail segment (118) in which ends (118A, 118B) are shaped to correspond to the angle (802) as described herein. This may be ed by manufacturing techniques such as crimping, or alternatively securing end caps to the top rail segment(s) (118) e.g. by welding, to provide the desired orientation for the ends (118A, 118B).

Trampoline construction James & Wells ref: 309172 It should however be appreciated that features of the technology described above may be used in combination with the features of the prior art shown in Figures 10 to 12. For example, in the embodiments of Figures 2A to 2F or Figure 4, the net poles (112) may instead be ed using the prior art arrangement shown in Figures 9 or 10 e.g. to the legs (1092, 1192).

In yet further ments, the connector-less design of Figures 5A to 5C and Figure 6, may also be modified such that the net pole (1090, 1190) is ed to the leg (1092, 1192) of the trampoline using any of the arrangements and components shown in Figures 9 or 10.

It should become apparent from the foregoing discussion that the present technology may e one or more improved method of assembly. For example, the assembly of the components described herein may involve one of more of the following steps in any order: a) Connecting the top rail segments (118) to form the top rail (104); b) Inserting at least one leg (108) into a corresponding aperture (220) in the top rail (104) or a connector (122) in the top rail (104); c) Engaging a locking mechanism so that a locking member (230) at least partially s into an aperture, to prevent removal of the leg(s) (108) from the top rail segment (118); d) Attaching feet (110) to one or more of the legs (108); e) Attaching a net pole (112) to at least one of the legs (108) and the top rail (104); f) Attaching a safety net (114) to one or more of the net poles (112); g) Attaching padding (116) to the trampoline; and h) Attaching the springs (106) to the support frame (104) and the mat (102) to the springs (102); i) Attaching accessories such as a .

It should be appreciated that variations to the assembly order may be made without departing from the spirit and scope of the technology.
