Description:
ATTACHMENT ASSEMBLY FOR A PLATFORM ASSEMBLY

The present disclosure pertains to an attachment assembly for a platform assembly and in particular to an attachment assembly for an inflatable platform assembly comprising an inflatable base. Further, a platform assembly and an accessory assembly are disclosed.

BACKGROUND

Outdoor activities are gaining increased interest in the community. In particular, activities on or in the water, such as canoeing, kayaking, and playing in water seems to grow tremendously.

Known equipment for outdoor activities is typically highly customized, not easy to handle, and/or not easy to assemble in particular not for multiuser-equipment, which in turn limits the number of different applications of this equipment. For example, pool rafts suffer from lack of stability and directional tracking making them unsuitable for sailing while canoes and kayaks suffer from the lack of a stable planar surface.

SUMMARY

Accordingly, there is a need for systems, devices and related methods enabling outdoor activities in an efficient and effective way.

An attachment assembly is provided and in particular an attachment assembly for a platform assembly, such as an inflatable platform assembly, comprising a base, a first pontoon, and a second pontoon.

The attachment assembly comprises a first attachment device configured to accommodate the first pontoon, a second attachment device configured to accommodate the second pontoon, and a primary base attachment device. The primary base attachment device comprises a primary base sleeve configured to accommodate at least part of the base. The primary base attachment device optionally comprises a first primary end band, e.g. configured to accommodate a first primary part of a first end of the base.

A platform assembly is disclosed. The platform assembly may comprise a base, such as an inflatable base having opposite first (distal) and second (proximal) surfaces and extending along a primary axis of the base. The platform assembly may comprise a first pontoon extending along a first pontoon axis from a first end to a second end of the first pontoon. The platform assembly may comprise a second pontoon extending along a second pontoon axis from a first end to a second end of the second pontoon. The platform assembly comprises an attachment assembly according to the present disclosure.

An accessory assembly for a platform assembly is disclosed. The accessory assembly comprises a first pontoon accessory band configured to accommodate at least a first portion of the first pontoon; a second pontoon accessory band configured to accommodate at least a second portion of the second pontoon; and one or more accessory devices configured for attachment to the first pontoon accessory band and the second pontoon accessory band.

A kit of parts comprising an inflatable base, a first pontoon, a second pontoon, an attachment assembly, and a container is disclosed. The base, the first pontoon, the second pontoon, and optionally the attachment assembly, may be configured to be contained in the container in a deflated state.

A platform system comprising a plurality of platform assemblies according to the disclosure is disclosed.

The platform system may provide a stiff modular platform system ensuring that the bases of the platform system stay in the same plane. Further, the base disclosed herein provides a high degree of freedom in the setup of the platform system allowing multiple different setups that can be tailored to different applications. Further, pontoons and/or attachment assembly can be used as support for accessory device(a), in turn reducing the stress on the base. The pontoons can be attached to base(s) in multiple setups and e.g. allowing a pontoon to support more than one base.

Further, the platform assembly/platform system may at least in some setups provide high directional tracking and/or stability due to the base(s) being raised and/or the directionality of the pontoons/stabilizers. The platform assembly can be packed to a size and shape that is suitable for a person, e.g. enabling a single person to conveniently carry the packed and compact platform assembly.

The present disclosure provides easy, stable, and secure assembly of a platform assembly. The present disclosure also provides easy and stable coupling of accessory devices to the platform assembly and/or platform system further increasing the applications of the platform assembly and/or platform system.

Also, the present disclosure reduces the sheer stress on the base(s) of the platform assembly/platform system, which is known to be a problem with drop-stitch plates.

Further, the positioning of pontoons below or proximal to the base, i.e. on the second surface of the base, facilitates land-based applications e.g. as a platform on wet ground, for example for tents or to reside on.

Attachment assembly

An attachment assembly for a platform assembly is provided. The platform assembly may comprise a base, a first pontoon, and a second pontoon. An attachment assembly may attach, such as secure, a pontoon or a plurality of pontoons to the base and/or to the attachment assembly, e.g. at or to the second (proximal) surface of the base. The attachment assembly may substantially prevent that the pontoon and the base are moving, e.g. with respect to each other, and avoid that the pontoon detaches from the platform assembly, such as from the base. The attachment assembly(s) may provide that the pontoon(s) and the base remains in substantially the same position after being assembled with the attachment assembly. The attachment assembly may provide that the pontoon(s) remain secured and fixed to the second surface of the base. In other words, the attachment assembly may provide an attachment system for the pontoons and the base.

The attachment assembly comprises a first attachment device configured to accommodate the first pontoon or at least a part of the first pontoon. The attachment assembly comprises a second attachment device configured to accommodate the second pontoon or at least a part of the second pontoon.

An attachment device, such as the first attachment device and the second attachment device, may attach, such as secure, a pontoon or a plurality of pontoons to the base and/or to the attachment assembly, e.g. at or to the second surface of the base. The attachment device(s) may substantially prevent that the pontoon is moving, e.g. avoid that the pontoon detaches from the platform assembly, such as from the base. The attachment device(s) may provide that the pontoon remains in substantially the same position after being attached, such as after being mounted or attached to the base. The attachment devices may provide that the pontoon(s) remain secured and fixed to the second surface of the base. In other words, the attachment device(s) may provide an attachment system for the pontoons on the second surface. Thus, the base is optionally configured to detachably attach one or more pontoons to the second surface of the base. The attachment assembly comprises a primary base attachment device. The primary base attachment device comprises a primary base sleeve configured to accommodate at least part of the base.

A base sleeve, such as the primary base sleeve and/or a secondary base sleeve, may be configured to accommodate at least a part of the base. A base sleeve, such as the primary base sleeve and/or a secondary base sleeve, may be configured to encircle the base in a direction perpendicular or parallel to the primary axis of the base. A base sleeve, such as the primary base sleeve and/or a secondary base sleeve, may have an inner circumference corresponding to the outer circumference of the base. In one or more exemplary attachment assemblies, the inner circumference of a base sleeve, such as the primary base sleeve and/or a secondary base sleeve, is in the range from 0.90 OC_B to 1 ,02 OC_B, where OC_B is the outer circumference of the base. The inner circumference of a base sleeve, such as the primary base sleeve and/or a secondary base sleeve, may be less than or equal to the outer circumference of the base. The inner circumference of a base sleeve, such as the primary base sleeve and/or a secondary base sleeve, may be adjustable, e.g. to allow the attachment assembly to be used with a variety of bases with different dimensions. A base sleeve, such as the primary base sleeve and/or a secondary base sleeve, may have a width in the range from 10 cm to 80 cm. The inner circumference of a base sleeve, such as the primary base sleeve and/or a secondary base sleeve, may be at least 1m, such as in the range from 1.5m to 6m. In one or more exemplary attachment assemblies, the inner circumference of a base sleeve, such as the primary base sleeve and/or a secondary base sleeve, is in the range from 1 ,5m to 3m or in the range from 3m to 5.5m.

A base sleeve, such as the primary base sleeve and/or a secondary base sleeve, may be configured to accommodate a part of the base perpendicular to the primary axis. In other words, a base sleeve, such as the primary base sleeve and/or a secondary base sleeve, may be configured to be arranged perpendicular to the main axis.

In one or more exemplary attachment assemblies, the primary base sleeve is configured to be arranged at a primary distance from the first end of the base, wherein the primary distance is less than 0.4 of the length of the base. In other words, a centre axis of the primary base sleeve may be configured to be arranged at a primary distance from the first end of the base, e.g. an end-to-center distance. The primary distance may be in the range from 0.05L to 0.4L, such as in the range from 0.15L to 0.25L, where L is the length of the base. The distance at which the primary base sleeve is arranged may be defined by the length of the end band, such as the length of a first primary end band and/or a first secondary end band.

The first attachment device and/or the second attachment device may be glued, stitched, welded, and/or melt-bonded to the primary base sleeve and/or the secondary base sleeve. In one or more exemplary attachment assemblies, the first attachment device and/or the second attachment device may be attached to a second part also denoted proximal part of the primary base sleeve and/or the secondary base sleeve configured to be arranged on the second surface also denoted proximal surface of base. The first attachment device may comprise one or more sleeves or tube elements (first sleeve(s), third part) as described herein with relation to the attachment device. The second attachment device may comprise one or more sleeves or tube elements (second sleeve(s), third part) as described herein with relation to the attachment device.

In an assembled state, the primary base sleeve may have a distal part arranged on the distal surface of the base, a proximal part arranged on the proximal surface of the base, and two side parts arranged on respective first and second sides of the base.

The primary base attachment device optionally comprises a first primary end band. The first primary end band may be configured to accommodate a first primary part of a first end of the base.

The first primary end band may be configured to accommodate a part, e.g. a first primary part, of the base parallel to the primary axis. In other words, the first primary end band may provide a cavity, such as an end stop for accommodating a part of the base. The first primary end band may be configured to be arranged parallel to the primary axis. The first primary end band may be attached to the primary base sleeve. The first primary end band may comprise a distal end attached to the distal part of the primary base sleeve and a proximal end attached to the proximal part of the primary base sleeve. The first primary end band may comprise an end part configured to be arranged at the first end of the base. An advantage of an end band, such as the first primary end band, may be that the base may be secured in a longitudinal direction, i.e. along the primary axis in relation to the attachment assembly. Further, an end band may ensure that the base is correctly positioned in the attachment assembly when assembling a platform assembly. The first primary end band and the primary base sleeve may be arranged perpendicular to each other. An end band, such as the first primary end band and the second primary end band may have width in the range of 5 cm to 50 cm, preferably in the range of 10 cm to 30 cm, such as 20 cm. A distance between a center axis of the first primary end band and a center axis of the first secondary end band may be in the range of 40 cm to 100 cm, preferably 50 cm to 90 cm, such as 60 cm, 70 cm or 80 cm. In other words, a center axis of the first primary end band may be configured to be arranged at a first primary distance from the first side of the base, e.g. a side-to-center distance.

In one or more exemplary attachment assemblies, the primary base attachment device comprises a first secondary end band configured to accommodate a first secondary part of the first end of the base. In other words, the first secondary end band may provide a cavity, such as an end stop for accommodating the first secondary part of the base. The first secondary end band may be configured to accommodate a part of the base parallel to the primary axis. In other words, the first secondary end band may be configured to be arranged parallel to the primary axis. The first secondary end band may be attached to the primary base sleeve. For example, the first secondary end band may be attached to the distal part of the primary base sleeve on one end (distal end) of the first secondary end band and to the proximal part of the primary base sleeve on the other end (proximal end) of the first secondary end band. In other words, a center axis of the first secondary end band may be configured to be arranged at a first secondary distance from the first side of the base, e.g. a side-to-center distance.

In one or more exemplary attachment assemblies, the first attachment device comprises a first primary pontoon sleeve or first primary attachment device attached to the primary base sleeve and being configured to position the first pontoon on a proximal side of the base. In one or more exemplary attachment assemblies, the first attachment device comprises a first secondary pontoon sleeve or first secondary attachment device attached to the primary base sleeve or to the secondary base sleeve and being configured to position the first pontoon on a proximal side of the base.

In one or more exemplary attachment assemblies, the second attachment device comprises a second primary pontoon sleeve or second primary attachment device attached to the primary base sleeve and being configured to position the second pontoon on a proximal side of the base. In one or more exemplary attachment assemblies, the second attachment device comprises a second secondary pontoon sleeve or second secondary attachment device attached to the primary base sleeve or to the secondary base sleeve and being configured to position the second pontoon on a proximal side of the base. A cavity of an attachment device, such as the first primary pontoon sleeve, the first secondary pontoon sleeve, the second primary pontoon sleeve, and/or the second secondary pontoon sleeve, may at least substantially have the shape of the pontoon being accommodated. The cavity may have a cross section smaller than the cross section of the accommodated pontoon in an inflated state. This may provide that the pontoon is securely attached to the sleeve/base and that the pontoon remains secured in a given position. The accommodated pontoon may thereby exert an outward force on the inner surface of a wall of the cavity/sleeve in an inflated state. A friction force between an outer surface of the accommodated pontoon and the inner surface of the wall of the cavity may thereby be provided.

A tube element/sleeve, such as the first primary pontoon sleeve, the first secondary pontoon sleeve, the second primary pontoon sleeve, and/or the second secondary pontoon sleeve, may comprise one or more layers, such as one or more fabric layers, being glued and/or stitched together. The tube element/sleeve may for example be made of heavy duty fabric, such as heavy duty nylon. The pontoon sleeve of an attachment device, such as the first primary pontoon sleeve, the first secondary pontoon sleeve, the second primary pontoon sleeve, and/or the second secondary pontoon sleeve may have a sleeve length also denoted SL in the range from 10 cm to 2 m, such as in the range from 15 cm to 50 cm such as 30 cm, and may form a cavity for accommodating a portion of a pontoon. In one or more example attachment assemblies, the attachment assembly comprises four pontoon sleeves.

In one or more exemplary attachment assemblies, the first primary pontoon sleeve is arranged on the first primary end band, such as attached to the first primary end band.

In one or more exemplary attachment assemblies, the first secondary pontoon sleeve is arranged on the first secondary end band, such as attached to the first secondary end band.

In one or more exemplary attachment assemblies, the second primary pontoon sleeve is arranged on the second primary end band, such as attached to the second primary end band.

In one or more exemplary attachment assemblies, the second secondary pontoon sleeve is arranged on the second secondary end band, such as attached to the second secondary end band. By having the pontoon sleeves arranged on the end bands, such as the first primary pontoon sleeve arranged on the first primary end band, the first pontoon and the second pontoon may be arranged in a direction perpendicular to the primary axis. This may be an advantage when a user wants to increase the portion of the pontoons extending further than the base or when a user wants to connect/assemble several platform assemblies together, e.g. to form a platform system.

In one or more exemplary attachment assemblies, the first primary pontoon sleeve and the first secondary pontoon sleeve are configured to attach the first pontoon with the first pontoon axis perpendicular to the primary axis.

In one or more exemplary attachment assemblies, the first primary pontoon sleeve and the first secondary pontoon sleeve are configured to attach the first pontoon with the first pontoon axis parallel to the primary axis.

In one or more exemplary attachment assemblies, the second primary pontoon sleeve and the second secondary pontoon sleeve are configured to attach the second pontoon with the second pontoon axis perpendicular to the primary axis.

In one or more exemplary attachment assemblies, the second primary pontoon sleeve and the second secondary pontoon sleeve are configured to attach the second pontoon with the second pontoon axis parallel to the primary axis.

In one or more exemplary attachment assemblies, the attachment assembly comprises a primary strap with a first end and a second end. The first end of the primary strap may be attached to the first primary pontoon sleeve and/or the second end of the primary strap may be attached to the second primary pontoon sleeve. The primary strap may extend in a direction perpendicular to the primary axis of the base and/or perpendicularly to the first pontoon axis and the second pontoon axis. The primary strap may be attached to an inner side of the first primary pontoon sleeve and/or an inner side of the second primary pontoon sleeve. The primary strap may ensure that the first pontoon and the second pontoon are kept at a substantially fixed distance from each other. Further, the primary strap may provide an increased stability to the platform assembly. The primary strap may counteract the forces exerted by the pontoons pulling away from each other. The primary strap may be made of the same material as the base sleeve. A strap, such as the primary strap and/or a secondary strap, may have a width in the range of 1 cm to 10 cm, preferably in the range of 2 cm to 8 cm, such as a width of 5 cm. A strap, such as the primary strap and a secondary strap, may be centered with respect to a pontoon sleeve. For example, the primary strap may be centered in view of the first primary pontoon sleeve and the second primary pontoon sleeve. The distance between the primary strap and the secondary strap may be in the range of 100 cm to 200 cm, preferably 120 cm to 180 cm, such as 140 cm, 150 cm or 160 cm.

In one or more exemplary attachment assemblies, the attachment assembly comprises a secondary base attachment device. The secondary base attachment device may comprise a secondary base sleeve configured to accommodate at least part of the base. The secondary base attachment device may comprise a second primary end band configured to accommodate a second primary part of a second end of the base.

In one or more exemplary attachment assemblies, the secondary base sleeve may be configured to be arranged at a secondary distance from the first end of the base, wherein the secondary distance is at least 0.6 of the length of the base. In other words, a centre axis of the secondary base sleeve may be configured to be arranged at a secondary distance from the first end of the base. The secondary distance may be in the range from 0.6L to 0.95L, such as in the range from 0.75L to 0.85L, where L is the length of the base 4. The distance at which the secondary base sleeve is arranged may be defined by the length of the end band, such as the length of a second primary end band and/or a second secondary end band. The primary base sleeve and the secondary base sleeve may be arranged at a constant distance from each other.

It is to be understood that the description of the primary base sleeve may also apply to the secondary base sleeve and vice versa.

In one or more exemplary attachment assemblies, the secondary base attachment device comprises a second secondary end band. The second secondary end band may be configured to accommodate a second secondary part of the second end of the base. The description of the first secondary end band may also apply to the second secondary end band.

In one or more exemplary attachment assemblies, the attachment assembly comprises a secondary strap with a first end and a second end. The first end may be attached to the first secondary pontoon sleeve and/or the second end may be attached to the second secondary pontoon sleeve. The secondary strap may extend in a direction perpendicular to the primary axis of the base and/or perpendicularly to the first pontoon axis and the second pontoon axis. The secondary strap may be attached to an inner side of the first secondary pontoon sleeve and/or an inner side of the second secondary pontoon sleeve. The secondary strap may ensure that the first pontoon and the second pontoon are kept at a substantially fixed distance from each other.

The sheet material may have a thickness in the range from 0.5 mm to 5 mm, such as in the range from 2 mm to 4 mm, e.g. about 3 mm.

Platform assembly and attachment assembly

A platform assembly is provided. The platform assembly comprises a base, such as an inflatable base having opposite first and second surfaces and extending along a primary axis of the base. The platform assembly comprises one or more pontoons including a first pontoon extending along a first pontoon axis from a first end to a second end of the first pontoon and/or a second pontoon extending along a second pontoon axis from a first end to a second end of the second pontoon. The platform assembly comprises an attachment device according to this disclosure for assembling the platform assembly. Platform assembly may be understood as a platform that is configured to float on water, such as a floating platform configured to float on the sea, a lake, a pool, and/or a river. Platform assembly may be understood as a platform that is configured to lay on a substantially planar surface, such as a ground surface. The platform assembly may be configured to support one or more objects and/or one or more users (such as human persons) above a support surface. The support surface may be a water surface, e.g. a water level, such as above a sea level, a ground surface, e.g. a ground level (for example for camping purposes). The platform assembly/base may for example act as a support surface for outdoor activities, such as camping, picnic, and/or outdoor eating. In other words, the platform assembly may provide an activity area to reside on. For example, when an outdoor ground surface is wet, muddy, and/or cold, the platform assembly may provide increased comfort for the user. The platform assembly may provide a rigid, plane, and/or dry surface for the user to lay, sit, sleep, and/or stand on. The platform assembly may for example act as a stand-up paddleboard (SUP boards), a raft (such as a sea-raft), a watersport platform, a leisure platform, a dock, an island platform, a floating terrasse, and/or a fishing platform. The platform assembly may be configured such that objects and/or users may stand on the platform assembly, such as stand on the distal part of the base sleeve. The platform assembly may be provided structurally stable, such that objects and/or users may stand, sit, and/or lay on the platform assembly in a stable way. The platform assembly may be configured to carry a certain weight without compromising the platform assembly. The platform assembly may be configured to carry at least 100 kg, such as at least 150 kg. In one or more platform assemblies, the platform assembly may be configured to carry at least 200 kg. The weight carried by the platform assembly may depend on the support surface that the platform assembly is used on and the dimension and size of the platform assembly. For example, the maximum carrying weight of the platform assembly may be larger when the platform assembly is used on land than when it is used on water.

It is an important advantage of the attachment assembly that simpler bases may be used in the platform assembly. Further, the forces on the base are better distributed in turn providing reduced tear and wear on the bases, which in turn increases the lifetime of the base/platform assembly.

The platform assembly comprising a base, a first pontoon, a second pontoon, and optionally an attachment assembly may have a weight less than 30 kg, such as less than 25 kg or even less than 20 kg. The platform assembly comprising a base, a first pontoon, a second pontoon, and optionally an attachment assembly may, in a packed state, have a volume less than 500 L, such as less than 400 L, e.g. about 300 L or even less than 250 L.

In one or more exemplary platform assemblies, the first pontoon and the second pontoon have a pontoon length of at least 1 .1 times the length of the base. By having pontoons being longer than the base, an increased stability of the platform assembly may be achieved. By having pontoons being longer than the base, a greater part of the base may secure to step/stand/be on for the user without having the platform assembly tipping. The platform assembly/base may comprise a secure area, where a user may step/stand/be on securely without having the platform assembly tipping more than a certain angle with respect to the support surface, and possibly result in the user falling from the platform assembly. This may be defined as a secure area of the platform assembly. Further, the ends of the pontoons extending further than the base may be used e.g. to attach equipment to the platform assembly.

In one or more exemplary platform assemblies, a centre axis of the first pontoon is arranged at a transversal distance less than 0.2W from a first side of the base, and a centre axis of the second pontoon is arranged at a transversal distance less than 0.2W from a second side of the base, wherein W is a width of the base. In other words, a pontoon distance between the pontoons may be at least 0.8W. By having an attachment assembly as disclosed herein, the first pontoon, the second pontoon, and the base are attached such that a centre axis of the first pontoon is arranged at a transversal distance less than 0.2W from a first side of the base, and a centre axis of the second pontoon is arranged at a transversal distance less than 0.2W from a second side of the base. An advantage of having the pontoons arranged within these boundaries, is that the pontoons are configured to support the base at a proximal surface of the base while the pontoons are as separated from each other as possible and preferably not supporting on a side surface of the base. This provides an improved stability of the platform assembly and an improved buoyancy with reduced stress on the attachment assembly.

Accessory assembly

An accessory assembly for a platform assembly is disclosed. The accessory assembly comprises a first pontoon accessory band configured to accommodate at least a first portion of the first pontoon. The accessory assembly comprises a second pontoon accessory band configured to accommodate at least a second portion of the second pontoon. The accessory assembly comprises one or more accessory devices configured for attachment to the first pontoon accessory band and the second pontoon accessory band. The first pontoon accessory band may comprise a first primary accessory coupling device and/or first secondary accessory coupling device for coupling the one or more accessory devices, and the second pontoon accessory band may comprise a second primary accessory coupling device and/or second secondary accessory coupling device for coupling the one or more accessory devices. Optionally, the accessory assembly comprises attachment portions between the pontoon accessory bands, e.g. attached to the first primary accessory coupling device and/or the second primary accessory coupling device, and the accessory device.

In one or more exemplary accessory assemblies, the one or more accessory devices comprises a first accessory device being a ladder device attached to the first pontoon accessory band and the second pontoon accessory band. The ladder device may be attached to the first primary accessory coupling device and/or to the second primary accessory coupling device. The ladder device may be used by a user of the platform assembly to come in and out of the water when the platform assembly is on the water.

The first pontoon accessory band may comprise a first handle, and the second pontoon accessory band may comprise a second handle, e.g. such that a user can pull himself up with the handles while standing on the ladder.

In one or more exemplary accessory assemblies, the one or more accessory devices comprises a second accessory device being a frame assembly for supporting further accessory devices, such as propulsion means, e.g. as an engine. The frame assembly may comprise a first crossbar and a second crossbar, wherein the first and second crossbar are configured to be arranged perpendicularly to the primary axis. The frame assembly may comprise a first pontoon part and a second pontoon part configured to be coupled to a coupling device of the pontoon sleeve and/or an accessory coupling device of a pontoon accessory band arranged respectively on an outer side of the pontoon sleeve and the pontoon accessory band.

Equipment

The equipment/accessories to be coupled to the platform assembly and/or the attachment assembly may comprise one or more of a privacy screen, a fishing rod holder, a table, a ladder, a rack, a frame, e.g. for coupling an engine, a paddle, a chair, a tent, a table, an insect net, a pole, a canopy, a camera, and a first surface attachment device.

Accessory devices

The platform assembly may comprise one or more accessory devices including a first primary accessory device configured to couple to the first pontoon, e.g. at a first end of the first pontoon, and/or to the second pontoon, e.g. at a first end of the second pontoon. By coupling the first primary accessory device to the first pontoon and/or the second pontoon, the coupling of heavier and more cumbersome accessory devices may be allowed compared to coupling to the base. The first pontoon and/or the second pontoon may be structurally stronger than the base of the platform assembly. It may therefore be advantageous to couple accessory devices that require a stronger coupling, e.g. the first primary accessory device, to the first pontoon and/or to the second pontoon, e.g. via the attachment assembly and/or the accessory assembly. Further, the first primary accessory device may provide a stabilizing effect to the platform assembly, e.g. such as a ballast effect and/or a counterweight when the weight distribution on the platform assembly is uneven. When using the platform assembly on water, the first primary accessory device may have a portion located below the water level and a portion located above the water level. The first primary accessory device may therefore enjoy the use of the buoyancy of the water, which minimizes the forces on the platform assembly. The first primary accessory device may comprise equipment itself or may comprise intermediate equipment for coupling further equipment to it. The first primary accessory device may comprise one or more of a ballast device, a ladder, an engine, a frame element a telescopic tube, and a support structure.

In one or more example platform assemblies, the accessory device(s) is removably coupled to the first pontoon and/or the second pontoon, e.g. removably coupled via a coupling device of the first pontoon and/or a coupling device of the second pontoon.

Kit of parts

A kit of parts is disclosed. The kit of parts comprises a base being an inflatable base, a first pontoon, optionally a second pontoon, optionally one or more attachment assemblies and a container, wherein the base, the first pontoon, optionally the second pontoon, and optionally the one or more attachment assemblies are configured to be contained in the container in a deflated state and/or packed state.

In one or more example platform assemblies, the base, the first pontoon, the second pontoon, and optionally attachment assembly in a deflated state and/or a packed state, are configured to be contained in (inner volume of) a container, such as a carriable container, e.g. a bag, a duffle bag, and/or a trolley. The weight of the container containing the deflated and/or packed platform assembly may be less than 30 kg, such as less than 25 kg or even less than 20 kg. The inner volume of the container may be less than 500 L, such as less than 400 L, e.g. about 300 L or even less than 250 L.

Base

A base is disclosed. The base may be a base for a platform assembly, or platform system as disclosed herein. In the present context, the base may also be denoted a first base and/or a second base. Thus, when referring to the base, reference is also made to the first base and/or the second base and vice versa. In the present context, the base may also be denoted a third base and/or a fourth base. The base is an inflatable base having opposite first (distal) and second (proximal) surfaces and extending along a primary axis of the base. The first surface may be positioned on a distal side or be a distal surface of the platform assembly, when in use. The first surface may be substantially planar, such that the first surface may be substantially parallel with the support surface, e.g. parallel with the water level or the ground level, when in use. In other words, the first surface may in an inflated state of the platform assembly provide a flat and rigid surface for the user and/or objects to reside on. The first surface may comprise a rough surface, e.g. a structured surface, at least on part of the first surface. In other words, the first surface may comprise a non-slippery surface, e.g. non-slippery for users having bare feet and/or wearing shoes, when standing, walking and/or running on the base. The base may be an inflatable first base, an inflatable second base, and/or an inflatable third base of a platform system. The base may be an inflatable fourth base of a platform system.

The second surface may be positioned on a proximal side or be a proximal surface of the platform assembly, when in use. The second surface may be substantially planar, such that the second surface may be substantially parallel with the support surface, e.g. parallel with the water level and/or ground level, when in use.

The base may extend along a primary axis from a first end to a second end. The primary axis may be a longitudinal axis. The primary axis may be parallel to the first surface and/or the second surface. The inflatable base may extend in a direction perpendicular to the primary axis, such as along a secondary axis, from a first side to a second side. The primary axis and/or the secondary axis may be parallel to the first surface and/or the second surface.

In one or more example platform assemblies and/or platform systems, the base has a thickness in the range from 3 cm to 20 cm. The thickness, also denoted T, of the base may be in the range from 5 cm to 20 cm, such as in the range from 8 to 18 cm, e.g. 12 cm or 15 cm. The thickness may be understood as a largest or a mean extension perpendicular to the primary axis and the secondary axis. The thickness of the base may be in an inflated state of the base.

The base may have a length, also denoted L and measured from the first end to the second end optionally along the primary axis, in the range from 80 cm to 4 m. In one or more exemplary bases, the length L is in the range from 1 m to 3 m, such as 1 .20 m, 1.8 m, or 2.4 m. The length may be understood as the largest extension of the base parallel to the first surface. The length of the attachment assembly may correspond substantially to the length of the base.

The base may have a width, also denoted W and measured from the first side to the second side, in the range from 50 cm to 4 m. In one or more exemplary bases, the width W is in the range from 0.8 m to 3 m, such as 1 .2 m, 1 .5 m, or 1.8 m. The width may be understood as the smallest extension of the base parallel to the first surface.

In one or more exemplary bases, the base may have the dimensions 15 cm (thickness) x 240 cm (length) x 120 cm (width). The ratio between the length and the width, L/W, may be in the range from 1 to 5, e.g. in the range from 1.5 to 3, such as 2, which may enable easy setup of platform system to different applications.

The base, e.g. the first surface/second surface, may be polygonal, e.g. with rounded corners. For example, the base may be rectangular, squared, pentagonal, hexagonal, or octagonal. The base may be circular, semi-circular, or oval.

In one or more example platform assemblies, platform systems, and/or inflatable assemblies, the base comprises or is made of a drop stitch fabric and optionally comprises a valve assembly for inflating and/or deflating the drop stitch fabric.

The base may comprise a first layer, such as a first plate, e.g. a first plate of drop stich material such as polyvinyl chloride, PVC. In other words, the base may comprise a dropstitch plate as a first layer. The base may comprise a second layer, such as a second plate, e.g. a second plate of foam material, such as EVA (ethylene-vinyl-acetate) foam. The second layer may be arranged on the first layer, such as attached to the first layer. The first layer may be arranged at the second surface of the base, e.g. forming the second surface. The second layer may be arranged at the first surface, e.g. forming the first surface. The first layer may have a thickness in the range of 2 cm to 40 cm. The second layer may have a thickness in the range from 0.2 cm to 10 cm. The second layer may have a thickness less than 5 mm, such as 1 mm, 2 mm, 3 mm, or 4 mm. The second layer may provide a comfortable surface for the user to stand on and/or anti-skid properties to the base. For example, the foam may be compressed by forces exerted on the first surface. The first layer may provide a stiff, rigid, and/or solid layer, in an inflated state of the base, thereby providing a rigid and uniform base, e.g. rigid and uniform first surface and/or second surface. The first layer may in a deflated state of the base provide a soft and flexible first layer, thereby providing a soft and flexible base that is suitable for packing, such as folding and/or rolling.

The base may be configured to be detachably attached to one or more pontoons with the attachment assembly, e.g. in one or a plurality of setups.

Pontoon

The platform assembly and/or platform system comprises one or more pontoons including a first pontoon extending along a first pontoon axis from a first end to a second end of the first pontoon. The first pontoon may be configured to, e.g. in a first setup, extend from the first end of the base to the second end of the base. The first pontoon may be an inflatable pontoon, e.g. an inflatable polyvinyl chloride, PVC, pontoon. Other suitable pontoon materials include Hypalon®, such as chlorosulfonated polyethylene (CSPE), rubber, polyurethane (PU), and synthetic rubber (CSM). The first pontoon may be deflatable. The first pontoon may in a deflated state of the first pontoon provide a soft and flexible pontoon, thereby providing a soft and flexible pontoon that is suitable for packing, such as folding and/or rolling. The first pontoon may be substantially cylindrical in shape, e.g. having a substantially circular cross-section. The first pontoon may provide a support for the base when in use, e.g. supporting the base, e.g. the first surface of the base, above a water-level and/or a ground level. When in use, the base may thereby not be in contact with the support surface and/or the surface medium, such as water and/or land. The first pontoon and/or the second pontoon may provide the main buoyancy for the platform assembly, e.g. when using the platform assembly on water. In other words, the first pontoon and/or the second pontoon may be a main air chamber for the platform assembly. In some platform assemblies, the base may be the main air chamber. The platform assembly may be configured such that a safety factor in the range of 1 to 2.5 with the main air chamber deflated in use, e.g. in case of emergency. When the platform assembly is in use, the first pontoon and/or the second pontoon may exert an upgoing force on the base, such as on the second surface a distal direction. For example, when used on water, the first pontoon and/or the second pontoon may provide buoyancy to the platform assembly, and make the platform assembly float. The pontoon(s) may be detachably attached to the base, e.g. via the attachment assembly.

In one or more example platform assemblies, the first pontoon has a first diameter in the range from 10 cm to 80 cm, such as in the range from 20 cm to 50 cm, e.g. 30 cm. The first pontoon may have a first length in the range from 40 cm to 4 m, such as in the range from 1 m to 3 m, e.g. 2.4 m. In one or more example platform assemblies, platform systems, and/or inflatable assemblies, the first pontoon has a first length in the range from 0.8L to 1 .5L where L is the length of the base or a first length in the range from 0.8W to 1 ,5W where W is the width of the base.

The platform assembly and/or platform system optionally comprises a second pontoon extending along a second pontoon axis from a first end to a second end of the second pontoon. The second pontoon may be configured to, e.g. in a first setup, extend from the first end of the base to the second end of the base. The second pontoon may be an inflatable pontoon, e.g. an inflatable polyvinyl chloride, PVC, pontoon. Other suitable pontoon materials include Hypalon®, such as chlorosulfonated polyethylene (CSPE), rubber, polyurethane (PU), and synthetic rubber (CSM). The second pontoon may be deflatable. The second pontoon may in a deflated state of the second pontoon provide a soft and flexible pontoon, thereby providing a soft and flexible pontoon that is suitable for packing, such as folding and/or rolling. The second pontoon may be substantially cylindrical in shape, e.g. having a substantially circular cross-section. The second pontoon may provide a support for the base when in use, e.g. supporting the base, e.g. the first surface of the base, above a water-level and/or a ground level. The second pontoon may be detachably attached to the base, e.g. via the attachment assembly.

The second pontoon may have a second diameter in the range from 10 cm to 80 cm, such as in the range from 20 cm to 50 cm, e.g. 30 cm. The second pontoon may have a second length in the range from 40 cm to 4 m, such as in the range from 1 m to 3 m, e.g. 2.4 m. In one or more example platform assemblies, platform systems, and/or inflatable assemblies, the second pontoon has a second length in the range from 0.8L to 1.5L where L is the length of the base or a first length in the range from 0.8W to 1 ,5W where W is the width of the base. The second pontoon may have the same size and/or shape as the first pontoon. Differently sized and/or shaped first pontoon and second pontoon may be employed.

The first length of the first pontoon and/or the second length of the second pontoon may be in the range from 0.3L to 0.7L, such as 0.5L, where L is the length of the base.

The first pontoon and/or the second pontoon may be inflatable and/or deflatable.

A platform system is provided. The platform system comprises a plurality of platform assemblies as disclosed herein. In one or more example platform systems, the platform system comprises a plurality of bases, such as three bases, four bases, five bases, or more, e.g. ten bases, or even twenty bases etc. In one or more example platform systems, the platform system comprises a plurality of pontoons, such as a number of pontoons corresponding to the number of bases, e.g. two pontoons per base. The platform system may be said to be modular, e.g. where the number of modules, such as basis and/or platform assemblies that are combined, may be varied. The platform system may provide an increased activity area to reside compared to the platform assembly. The platform system may be arranged in various setups depending on the use of the platform. The attachment assembly may provide an increased flexibility for the platform system. For example, the user of the platform system may arrange the platform system in various setups as a result of the attachment assembly. The platform system may provide a rigid, plane, and/or dry surface for the user to lay, sit, sleep, and/or stand on. The platform system and/or platform assembly may for example act as a stand-up paddleboard (SUP boards), a raft (such as a sea-raft), a water-sport platform, a leisure platform, a dock for e.g. a boat or a jet-ski, an island platform, a floating terrasse, and/or a fishing platform. Advantageously, the platform
