DETAILED DESCRIPTION

Various exemplary embodiments and details are described hereinafter, with reference to the figures when relevant. It should be noted that the figures may or may not be drawn to scale and that elements of similar structures or functions are represented by like reference numerals throughout the figures. It should also be noted that the figures are only intended to facilitate the description of the embodiments. They are not intended as an exhaustive description of the disclosure or as a limitation on the scope of the disclosure. In addition, an illustrated embodiment needs not have all the aspects or advantages shown. An aspect or an advantage described in conjunction with a particular embodiment is not necessarily limited to that embodiment and can be practiced in any other embodiments even if not so illustrated, or if not so explicitly described.

The figures are schematic and simplified for clarity, and they merely show details which aid understanding the disclosure, while other details have been left out. Throughout, the same reference numerals are used for identical or corresponding parts.

In the following, whenever referring to proximal side or surface of a layer, an element, a device or part of a device, the referral is to the side closest to or the surface facing a support surface or medium (such as water and/or land), when the platform assembly, platform system, and/or inflatable assembly is in use. Likewise, whenever referring to the distal side or surface of a layer, an element, a device or part of a device, the referral is to the side furthest away from or the surface facing away from the support surface or medium, when the platform assembly and/or platform system is in use. In other words, the proximal side or surface is the side or surface closest to the support surface or medium (such as water), when the platform assembly, platform system, and/or inflatable assembly is in use and the distal side is the opposite side or surface - the side or surface furthest away from the support surface or medium (such as water and/or land or ground) in use.

Inflatable assembly and method of assembling an inflatable assembly

An inflatable assembly is provided. The inflatable assembly comprises an inflatable device comprising a first surface and one or more coupling devices including a first coupling device arranged on the first surface. The first coupling device is configured to accommodate a first coupling element optionally having a first planar surface for coupling equipment to the inflatable device.

A method of assembling an inflatable assembly comprising an inflatable device with a first coupling device is disclosed. The method comprises arranging a first coupling element having a first planar surface at the first coupling device, e.g. at or in a first pocket device, such as in a first pocket. The method comprises inflating the inflatable device to secure the first coupling element to the first coupling device. When inflating the inflatable device, the first surface may be tensioned and thereby also the first coupling device, e.g. the first pocket device, such as the first sheet and/or the second sheet. By tensioning the inflatable device, such as the first surface, the first pocket device, the first sheet and/or the second sheet the first coupling element may be secured, e.g. secured in the first pocket device. This may avoid that the first coupling element detaches and/or falls out of the first coupling device, e.g. of the first pocket device.

The inflatable device may be one of a base, e.g. as disclosed herein, a pontoon, e.g. as disclosed herein, a kayak, a boat, a raft, a dock, a canoe, dinghy, and/or a mattress. The inflatable device may be comprised in a platform assembly according to this disclosure.

Platform assembly

A platform assembly is provided. The platform assembly comprises a base and one or more pontoons including a first pontoon and/or a second pontoon. 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 water-sport 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 first surface.

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.

The platform assembly comprising a base, a first pontoon, and a second pontoon 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, and a second pontoon 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.

The platform assembly comprises a first base, e.g. a based disclosed herein, and one or more pontoons including a first pontoon. The method comprises inflating the first base, e.g. a base as disclosed herein. Inflating the first base may comprise to inflate the first base to a pressure larger than 0.1 bar or larger than 0.15 bar, such as to a pressure in the range of 0.2 bar to 3 bar. The first base may be inflated via the valve assembly of the base. The base may be inflated using one or more of a hand pump, a compressor, an electrical pump, and a foot pump.

The method optionally comprises inflating the second base, e.g. a base as disclosed herein. Inflating the second base may comprise to inflate the second base to a pressure larger than 0.1 bar or larger than 0.15 bar, such as to a pressure in the range of 0.2 bar to 3 bar. The second base may be inflated via the valve assembly of the base. The base may be inflated using one or more of a hand pump, a compressor, an electrical pump, and a foot pump.

The method comprises arranging the first pontoon in an attachment device of the first base, e.g. in the first primary attachment device or in a third attachment device of the first base. The method being a method for assembling a platform assembly optionally comprises arranging the first pontoon in the first secondary attachment device of the first base.

The method optionally comprises arranging the first pontoon in an attachment device of the second base, e.g. the first secondary attachment device or a third attachment device of the second base.

The method comprises inflating the first pontoon to secure the first pontoon in relation to the first base and optionally the second base and/or to secure the first base in relation to the second base. The first base and the second base may be attached, e.g. via the first pontoon, such that a stiff attachment and/or connection is provided between the first base and the second base. The first pontoon may connect the first base with the second base, e.g. in a way such that the first base and the second base do substantially not move relative to each other.

In one or more example methods, the method comprises, prior to arranging the first pontoon in an attachment device of the first base, inflating the first pontoon to a first configuration. Inflating the first pontoon to a first configuration may comprise inflating the first pontoon to a first pressure, a first size or dimension, a first length, and/or a first width. The first configuration may be understood as an intermediate configuration, such as an intermediate shape, of the first pontoon. In other words, inflating the first pontoon to a first configuration may comprise to inflate the first pontoon to give the first pontoon an intermediate shape before arranging the first pontoon in the attachment device of the first base. An advantage of this, may be that the first pontoon can be partially inflated such that the first pontoon is rigid enough to be handled easily, but not so rigid that the first pontoon cannot be arranged in the attachment device afterwards.

Inflating the first pontoon to secure the first pontoon in relation to the first base and optionally the second base and/or to secure the first base in relation to the second base optionally comprises inflating the first pontoon to a second configuration. Inflating the first pontoon to a second configuration may comprise inflating the first pontoon to a second pressure, a second size or dimension, a second length, and/or a second width. The second pressure of the first pontoon may be larger than 0.1 bar or larger than 0.15 bar, such as in the range from 0.2 bar to 3 bar. The second configuration may be understood as a mounted configuration, such as a final configuration, e.g. as a mounted shape, of the first pontoon. In other words, inflating the first pontoon to a second configuration may comprise to inflate the first pontoon to provide a secure attachment of the first pontoon and/or to secure the first base in relation to the second base. The second configuration may provide the final installed shape to the first pontoon when it has been arranged in the attachment devices of the first base and/or of the second base. An advantage of this, may be that the first pontoon may achieve a tight fit in the attachment devices when the first pontoon is arranged in the attachment devices of the first base and/or the second base. The second configuration of the first pontoon may provide that the first pontoon is rigid and does substantially not move when arranged in the attachment device(s).

In one or more example methods, platform assemblies, platform systems, and/or inflatable assemblies, inflating the first pontoon to a first configuration is performed prior to arranging the first pontoon in an attachment device of the second base.

In one or more example methods, platform assemblies, platform systems, and/or inflatable assemblies, inflating the first pontoon to a second configuration is performed after arranging the first pontoon in an attachment device of the second base, e.g. to secure the first pontoon to the second base.

An advantage of inflating the first pontoon to a second configuration after arranging the first pontoon may be that a tight fit, e.g. a snug fit of the first pontoon in the attachment devices, such as a sleeve, may be achieved. For example, the attachment device(s), such as a sleeve or tube element, may have a smaller cross section than the first pontoon in inflated state. The first pontoon may thereby exert an outward force on the inner surface of tube element and/or sleeve, e.g. a wall of the first primary cavity, in an inflated state, such as a second configuration. A friction force between an outer surface of the first pontoon and the inner surface of tube element and/or sleeve, e.g. the wall of the first primary cavity may thereby be provided. This may avoid that the first base and the second base move apart from each other, e.g. when in use, for example on water. The platform system and/or platform assembly may be easier to assemble before the first pontoon is inflated. It may be more secure and easier for the user to provide one assembled platform system and/or platform assembly before using it.

In one or more example methods, the method comprises arranging a second pontoon in an attachment devices of the first base and the second base.

In one or more example methods, the method comprises inflating the second pontoon to secure the second pontoon in relation to the first base and optionally the second base and/or to secure the first base in relation to the second base. The method optionally comprises inflating the second pontoon to secure the second pontoon in relation to the first base and optionally the second base and/or to secure the first base in relation to the second base. The first base and the second base may be attached, e.g. via the second pontoon, such that a stiff attachment and/or connection is provided between the first base and the second base. The second pontoon may connect the first base with the second base, e.g. in a way such that the first base and the second base do substantially not move relative to each other.

Inflating the second pontoon to a first configuration may comprise inflating the second pontoon to a first pressure, a first size or dimension, a first length, and/or a first width. The first configuration may be understood as an intermediate configuration, such as an intermediate shape, of the second pontoon. In other words, inflating the second pontoon to a first configuration may comprise to inflate the second pontoon to give the second pontoon an intermediate shape before arranging the second pontoon in the attachment device of the first base. An advantage of this, may be that the second pontoon can be partially inflated such that the second pontoon is rigid enough to be handled easily, but not so rigid that the second pontoon cannot be arranged in the attachment device afterwards.

In one or more example methods, inflating the second pontoon to secure the second pontoon in relation to the first base and optionally the second base and/or to secure the first base in relation to the second base comprises inflating the second pontoon to a second configuration. Inflating the second pontoon to a second configuration may comprise inflating the second pontoon to a second pressure, a second size or dimension, a second length, and/or a second width. The second pressure of the second pontoon may be larger than 0.1 bar or larger than 0.15 bar, such as in the range from 0.2 bar to 3 bar. The second configuration may be understood as a mounted configuration, such as a final configuration, e.g. as a mounted shape, of the second pontoon. In other words, inflating the second pontoon to a second configuration may comprise to inflate the second pontoon to provide a secure attachment of the second pontoon and/or to secure the first base in relation to the second base. The second configuration may provide the final installed shape to the second pontoon when it has been arranged in the attachment devices of the first base and/or of the second base. An advantage of this, may be that the second pontoon may achieve a tight fit in the attachment devices when the second pontoon is arranged in the attachment devices of the first base and/or the second base. The second configuration of the second pontoon may provide that the second pontoon is rigid and does substantially not move when arranged in the attachment device(s).

In one or more example methods, inflating the first base comprises inflating the first base to a first configuration prior to arranging the first pontoon in attachment devices of the first base.

Inflating the first base to a first configuration may comprise inflating the first base to a first pressure, a first size or dimension, a first length, and/or a first width. The first pressure of the first base may be less than 0.2 bar or even less than 0.1 bar.

In other words, the first configuration may comprise to inflate the first base to give it an intermediate shape before arranging the first pontoon in the attachment device of the first base. An advantage of this, may be that the first base may be partially inflated such that the first base is rigid enough to be handled easily, but not so rigid that the first pontoon cannot be arranged in the attachment device afterwards.

In one or more example methods, inflating the first base comprises inflating the first base to a second configuration, e.g. after arranging the first pontoon in attachment devices of the second base.

Inflating the first base to a second configuration may comprise inflating the first base to a second pressure, a second size or dimension, a second length, and/or a second width.

In other words, inflating the first base to a second configuration may comprise to inflate the first base to provide a secure attachment of the first pontoon and/or to secure the first base in relation to the second base. The second configuration of the first base may provide the final installed shape to the first pontoon and/or the second pontoon when the first pontoon and/or second pontoon have been arranged in the attachment devices of the first base and/or of the second base. An advantage of this, may be that the first pontoon and/or the second pontoon may achieve a tight fit in the attachment devices when being arranged in the attachment device of the first base and/or the second base. The second configuration of the first base may provide that the first pontoon and/or the second pontoon is rigid and does substantially not move when arranged in the attachment device(s).

In one or more example methods, platform assemblies, platform systems, and/or inflatable assemblies, inflating the second base comprises inflating the second base to a first configuration, e.g. prior to arranging the first pontoon in attachment devices of the second base. Inflating the second base to a first configuration may comprise inflating the second base to a first pressure, a first size or dimension, a first length, and/or a first width. The first pressure of the second base may be less than 0.2 bar or even less than 0.1 bar. The first configuration may be understood as an intermediate configuration, such as an intermediate shape, of the second base. In other words, the first configuration may comprise to inflate the second base to give the second base an intermediate shape before arranging the first pontoon and/or the second pontoon in the attachment device(s) of the second base. An advantage of this, may be that the second base may be partially inflated such that the second base is rigid enough to be handled easily, but not so rigid that the first pontoon and/or second pontoon cannot be arranged in the attachment device afterwards.

In one or more example methods, platform assemblies, platform systems, and/or inflatable assemblies, inflating the second base comprises inflating the second base to a second configuration, e.g. after arranging the first pontoon in attachment device(s) of the second base. Inflating the second base to a second configuration may comprise inflating the second base to a second pressure, a second size or dimension, a second length, and/or a second width. The second pressure of the second base may be larger than 0.1 bar or larger than 0.15 bar, such as in the range from 0.2 bar to 3 bar.

Base

A base is disclosed. The base may be a base for a platform assembly, inflatable 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 and second 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, platform systems, and/or inflatable assemblies, the base has a thickness in the range from 2 cm to 40 cm. The thickness, also denoted T, of the base may be in the range from 5 cm to 30 cm, such as in the range from 8 to 20 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 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 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 detachably attach one or more pontoons to the second surface of the base, 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 first pontoon may be detachably attached to the base, e.g. via attachment device(s). The first pontoon may be configured to be detachably attached to the base in a first setup and optionally in a second setup. In other words, the second pontoon may be attached to one attachment device, e.g. a first primary attachment device, in a first setup and to another attachment device, e.g. a third attachment device in a second setup. In one or more example platform assemblies, platform systems, and/or inflatable 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 1.2L where L is the length of the base or a first length in the range from 0.8W to 1 ,2W 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 attachment device(s). The second pontoon may be configured to be detachably attached to the base in a first setup and optionally in a second setup. In other words, the second pontoon may be attached to one attachment device, e.g. a second primary attachment device, in a first setup and to another attachment device, e.g. a fourth, fifth, or sixth attachment device, in a second setup.

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 1.2L where L is the length of the base or a first length in the range from 0.8W to 1 ,2W 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.

Attachment devices

The base optionally comprises one or more attachment devices arranged on the second surface.

An attachment device may attach, such as secure, a pontoon or a plurality of pontoons to the base, 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 one or more 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 one or more attachment devices comprise a first set of one or more first attachment devices including a first primary attachment device and/or a first secondary attachment device, e.g. for attaching the first pontoon to the base/second surface optionally with the first pontoon axis parallel to the primary axis, e.g. in a first setup.

The first primary attachment device may be arranged at a distance of 0.1 L to 0.5L, such as 0.25L, from the first end of the base and/or at a distance of 0.1 W to 0.4W, such as 0.2W from the first side of the base. The first secondary attachment device may be arranged at a distance of 0.5L to 0.9L, such as 0.75L, from the first end of the base and/or at a distance of 0.1 W to 0.4W, such as 0.2W from the first side of the base. In one or more exemplary platform assemblies/bases, the first set of first attachment devices may be configured to attach the first pontoon with the first pontoon axis forming a first primary angle with the primary axis of the base. The first primary angle also denoted V_1_1 , may be in the range from 0 to 90°, e.g. less than 75°, such as in the range from 30° to 60°. An attachment device, such as one or more of first primary attachment device, first secondary attachment device, second primary attachment device, and second secondary attachment device may comprise one or more of a buckle, a D-ring, a grommet, an eyelet, a belt, a strap, a clip, a clamp, a harness, a fastener, a hasp, a catch, and a hook-and- loop fastener.

An attachment device, such as one or more of first primary attachment device, first secondary attachment device, second primary attachment device, and second secondary attachment device may comprise a first part and/or a second part attached to the base at the second surface. An attachment device may comprise one or more parts attached to the pontoon.

An attachment device may comprise a first part attached to the second surface of the base. An attachment part may comprise a second part attached to the second surface. The first part and the second part may be attached to a common support that is attached to the second surface.

The first part optionally comprises a first attachment region and/or a second attachment region, where the first part is attached to the second surface, e.g. glued, stitched, welded, or melt-bonded to the second surface. The second part optionally comprises a first attachment region and/or a second attachment region, where the second part is attached to the second surface, e.g. glued, stitched, welded, or melt-bonded, to the second surface. The first part may comprise a first strap attached at the first attachment region at one end and at the second attachment region at another end, e.g. to the second surface or to a first support. The first strap may be glued, stitched, welded, and/or melt-bonded to the first support at first end and second end. The first support may be glued, stitched, welded, and/or melt-bonded, to the second surface. The first strap may form a first bridge section forming an opening between the bridge section and the second surface and/or the first support of the first part. The second part may comprise a second strap attached at the first attachment region at one end and at the second attachment region at another end, e.g. to the second surface or to a second support. The second strap may be glued, stitched, welded, and/or melt-bonded to the second support at first end and second end. The second support may be glued, stitched, welded, and/or melt-bonded, to the second surface. The second strap may form a second bridge section forming an opening between the bridge section and the second surface. The distance between the first attachment region and the second attachment region of a part, e.g. the first part and/or the second part, may be in the range of 1 cm to 10 cm, such as 5 cm or 6 cm. Optionally, the first part may comprise a first support and/or the second part may comprise a second support being attached to the second surface. The first strap of first part may be attached to the first support in first and second attachment regions. The second strap of second part may be attached to the second support in first and second attachment regions.

An attachment device, such as one or more of first primary attachment device, first secondary attachment device, second primary attachment device, and second secondary attachment device may comprise a part, also denoted third part, being free (such as not attached to either the base or the pontoon) in a disassembled state of the platform assembly, and which third part is attached to the first part and/or second part attached to the base in an assembled state of the platform assembly.

The third part of an attachment device may comprise a belt or strap for encircling a pontoon in assembled state. The third part optionally comprises a tube element or sleeve. When assembled, the belt or strap may encircle the tube element. The third part, e.g. tube element and/or sleeve may form a cavity, e.g. together with the second surface, for accommodating a pontoon. The belt of the attachment device optionally encircles the sleeve or tube element and the pontoon accommodated in the cavity and passes through respective openings of first part and/or second part of the attachment device to secure and attach the pontoon to the second surface of the base. A cavity formed by the third part/sleeve may have a first opening at a first end of the cavity and/or a second opening at a second end of the cavity. First and second openings in a cavity allows for a pontoon to extend on both sides of the sleeve/tube element, which may ensure that the pontoon ends are free, e.g. such that accessory device can be attached to ends of the pontoon.

The belt or strap of third part may have a width in the range from 1 cm to 10 cm, e.g. 5 cm. The belt or strap of third part may have a length in the range from 50 cm to 3 m.

A cavity of an attachment device, such as the third part, 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 base. The accommodated pontoon may thereby exert an outward force on the inner surface of a wall of the cavity 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. The tube element/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 tube element of an attachment device may have a sleeve length also denoted SL in the range from 10 cm to 2 m, such as 30 cm, and may form a cavity for accommodating a portion of a pontoon. The belt may have a width in the range from 2 cm to 10 cm and optionally encircles tube element and pontoon in assembled state. It is to be understood that the third part of attachment device comprising tube element and/or belt can be used with different types of first part and second part of attachment device, e.g. as illustrated in Fig. 9A, 9B and 9C. Further, a third part may be used for different first and second parts in different setups of platform assembly/platform system. Thus, a base may comprise fewer third parts than first parts of attachment devices. In one or more example platform assemblies, the base comprises four third parts. The third part may comprise a buckle for fastening the belt or strap around the pontoon. The buckle of the third part may be provided with a release capability configured to release when a force applied to the buckle increase above a threshold. The third part may be detachably attached to the first part and/or the second part. The third part may be detachably attached to the pontoon.

In one or more exemplary attachment devices, the third part comprises a first strap optionally attached to a tube element of the third part and a second strap optionally attached to the tube element. In assembled state, the first strap may be attached to the first part and the second strap may be attached to the second part. In assembled state, the first strap and/or the second strap may extend through openings of the first part and/or the second part to secure the tube element and thereby the pontoon to the second surface.

In one or more exemplary platform assemblies and/or platform systems, a third part may be used as a part in different attachment devices in different setups. For example, a third part of the first primary attachment device in a first setup may be used as a third part of a third attachment device in a second setup. Further, a third part of the second primary attachment device in a first setup may be used as a third part of a fourth attachment device in a second setup.

An attachment device or parts thereof may be packed away at the second surface, such as folded up against the second surface, when not in use. In other words, not all of the one or more attachment devices may be in use at the same time, and therefore the attachment devices that are not in use, may be packed up, e.g. to a passive state. For example, when no pontoons are attached to the base, some, most, and/or all of the one or more attachment devices may be packed up. An advantage of packing up the non-used one or more attachment devices, may be that they are not in the way, such as being of trouble, at the second surface. Further, the non-used attachment devices may not be prejudicial for e.g. the flowing of the platform assembly when on water, or get stuck to various objects.

In one or more example platform assemblies, platform systems, and/or inflatable assemblies, the first primary attachment device comprises a first part attached to or integrated into the second surface. The first primary attachment device may comprise a second part attached to or integrated into the second surface. The first part and/or the second part of the attachment device may for example be glued to, welded, and/or stitched to the second surface of the base. For example, the first part and/or second part of the attachment device may comprise a piece of fabric or PVC that is stitched, welded, and/or glued to the second surface.

The first part of an attachment device may comprise one or more first coupling elements at a distal edge of the first part. The second part of an attachment device optionally comprises one or more second coupling elements at a distal edge of the second part for coupling the distal edges of the first part and the second part. The one or more first coupling elements and/or the one or more second coupling elements may comprise one or more of a buckle, a D-ring, a grommet, an eyelet, a belt, a strap, a clip, a clamp, a harness, a fastener, a hasp, a catch, and a hook-and-loop fastener.

In one or more example platform assemblies, platform systems, and/or inflatable assemblies, the first primary attachment device comprises a third part including a tube element and/or a belt.

In general, the third part of attachment device may comprise a strap element enclosing tube element. The third part may comprise a rope. The third part may comprise an elastic belt, spring element, or spring function e.g. for uptake of sideward oscillations or forces on the pontoon. The third part of the attachment device may be a “free” part (such as not attached to either the base or the pontoon) in a disassembled state of the platform assembly. The third part may be attached to the second surface, the first part, and/or second part in an assembled state of the platform assembly, e.g. when a pontoon is attached to the base via the one or more attachment devices. The third part may be detachably arranged to the base and/or the first part and/or the second part. The third part may be attached to the base, such as the second surface, the first part and/or the second part. The third part may comprise a sleeve, such as the first primary sleeve and/or the second primary sleeve.

The one or more attachment devices may comprise a second set of one or more second attachment devices including a second primary attachment device and/or a second secondary attachment device, e.g. for attaching the second pontoon to the base optionally with the second pontoon axis parallel to the primary axis. The second primary attachment device may be arranged at a distance of 0.1 L to 0.5L, such as 0.25L, from the first end of the base and/or at a distance of 0.6W to 0.9W, such as 0.8W from the first side of the base. The second secondary attachment device may be arranged at a distance of 0.5L to 0.9L, such as 0.75L, from the first end of the base and/or at a distance of 0.6W to 0.9W, such as 0.8W from the first side of the base.

In one or more exemplary platform assemblies/bases, the second set of second attachment devices may be configured to attach the second pontoon with the second pontoon axis forming a second primary angle with the primary axis of the base. The second primary angle also denoted V_2_1, may be in the range from 0 to 90°, e.g. less than 75°, such as in the range from 30° to 60°.

The first pontoon axis and the second pontoon axis may, e.g. in first setup and/or in second setup, be parallel. In other words, the first set of first attachment devices and the second set of second attachment devices may be configured to attach the first pontoon and the second pontoon to the second surface, respectively, such that the first pontoon axis is parallel to the second pontoon axis. In one or more exemplary platform assemblies/bases, the first set of first attachment devices and the second set of second attachment devices may be configured to attach the first pontoon and the second pontoon to the second surface with the first pontoon axis and the second pontoon axis forming a pontoon angle e.g. in the range from 0 to 90°, e.g. less than 75°, such as in the range from 30° to 60°.

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. 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, platform systems, and/or inflatable assemblies, the first pontoon comprises a first coupling device for coupling the first primary accessory device to the first pontoon, e.g. at a first end of the first pontoon. The first primary accessory device may be coupled directly to the first pontoon or via the first coupling device.

For example, the first coupling device may be the same sleeve as the sleeve for accommodating the first pontoon, e.g. the first primary sleeve being longer and/or wider such that the first primary accessory device may be accommodated in the first primary sleeve as well. The first coupling device may also comprise or be an additional sleeve or tube element attached to the second surface and/or the pontoon. The additional sleeve/tube element may for example be positioned further away from the ends of the base, i.e. towards the center of the base. This may provide an increased support of the first primary accessory device, e.g. when applying force/pressure on the primary accessory device.

In one or more example platform assemblies, platform systems, and/or inflatable assemblies, the one or more accessory devices comprise a first secondary accessory device configured to couple to the first pontoon, e.g. at a second end of the first pontoon, and/or to the second pontoon, e.g. at a second end of the second pontoon.

In one or more example platform assemblies, platform systems, and/or inflatable assemblies, the first primary accessory device comprises a ballast device and wherein the ballast device is coupled to a first end of the first pontoon. The ballast device may provide a ballast effect and/or a counterweight when the weight distribution on the platform assembly is uneven. The ballast device may comprise a bag element configured to be filled up. The bag element may be filled up with weights, such as sand and/or stones, or may when used on water, be filled up with water. The ballast device may also comprise a solid weight. The ballast device may comprise one or more steps, e.g. to be used as a ladder for the user of the platform assembly. The ballast device may comprise a first primary ballast device configured to be positioned at a first end of the first pontoon, a first secondary ballast device configured to be positioned at a second end of the first pontoon, a second primary ballast device configured to be positioned at a first end of the second pontoon, and/or a second secondary ballast device configured to be positioned at a second end of the second pontoon.

When using the platform assembly on water, the ballast device may have a portion located below the water level and a portion located above the water level when the platform assembly is tilting. The ballast device may in case of tilting of the platform assembly have a portion located above the water level, which will have an increased weight, as the portion located above the water level increases. The ballast device may therefore have a variating counterweight effect depending on the distribution of the weight on the platform assembly. Further, this may minimize the forces exerted on the platform assembly, e.g. on the first pontoon when the platform assembly has a uniform weight distribution on the first surface.

In one or more example platform assemblies, platform systems, and/or inflatable assemblies, the first primary accessory device comprises a frame element. The frame element may comprise one or more of a metal frame, a rigid polymer frame, fiber material, such as glass fiber and/or carbon fiber, e.g. reinforced fiber material, and/or a wooden frame.

Optional second layer 9 of inflatable device may overlap attachment regions 294, 296. The second sheet 293 and thus the coupling device is glued, welded, stitched, and/or melt-bonded to the first surface. The window 224 of coupling device is formed in the first sheet 292 to expose the planar surface of the coupling element removable inserted in the pocket 291. The coupling of the equipment may be performed through the first sheet, i.e. with the first sheet between the first coupling element and the equipment, e.g. via magnetic coupling.

Optionally, the second opening 299 may be directed towards a side and/or end of the base. Optionally, the first opening 298 and/or the second opening 299 may be at an edge of the base, e.g. a first sheet and/or a second sheet may be stitched and/or glued at an edge of the base. The first coupling element 222 shown with dashed circle and inserted in the pocket of the coupling device is a 3 mm thick metal plate having a circular shape with a diameter CD_1 and made of stainless stee, wherein the diameter CD_1 is larger than the diameter of window 224. The pocket device in Fig. 13 comprises a second sheet arranged between the first sheet 292 and the first surface 212, 10. The second sheet is attached, such as glued, welded, stitched, and/or melt-bonded, to the first sheet 292 in attachment regions 294, 296, 297A, and optionally 297B and attached, such as glued, welded, stitched, and/or melt-bonded to the first surface 212, 10. The window 224 in the first sheet 292 is configured to expose at least a portion, such as part of the planar surface, of the coupling element inserted in the pocket, e.g. the first coupling element 222 arranged or accommodated in the coupling device. By exposing a portion of the coupling element, such as the planar surface, equipment may be coupled directly to the coupling element accommodated in the coupling device. This may be an advantage, for example for exposing a smooth surface of a metal plate or of a polymer plate, e.g. for magnetic coupling and/or for suction coupling of equipment to the planar surface.

The first planar surface and window may form a first coupling area 223 for coupling equipment to the inflatable device 210, 4, e.g. to the first coupling device 220. As illustrated in Fig. 13, the first window 223 may have an area that is smaller than the first coupling element, such that the first coupling element 222 is secured in the first pocket device 290 when in use.

The first coupling element 222 may be removably attached or fixed to the first coupling device 290, e.g. via the first opening 298.

A pontoon 6, 6A, 8, 8A may optionally comprise a coupling device, such as a first coupling device 310. The first coupling device 310 of pontoon may for example comprise or be a strap element, an additional sleeve and/or a tube element attached to the second surface and/or the pontoon 6, 6A, 8, 8A.

The method 400 optionally comprises S112 arranging a second pontoon in an attachment devices of the first base and/or the second base and optionally inflating S114 the second pontoon to secure the second pontoon in relation to the first base and optionally the second base and/or to secure the first base in relation to the second base.

Further, the method 400 optionally comprises, prior to arranging S112 the second pontoon in an attachment device of the first base, inflating S111 the second pontoon to a first configuration with a first pressure, a first size or dimension, a first length, and/or a first width. In method 400, inflating S114 the second pontoon optionally comprises inflating S114A the second pontoon to a second configuration with a second pressure, a second size or dimension, a second length, and/or a second width.

Fig. 19 is a flow chart of an exemplary method according to this disclosure. The method 500 is a method of assembling an inflatable assembly comprising an inflatable device with a first coupling device, the method 500 comprising arranging S202 a first coupling element having a first planar surface at the first coupling device, e.g. at or in a first pocket device, such as in a first pocket. The method 500 comprises inflating S204 the inflatable device to secure the first coupling element to the first coupling device optionally followed by coupling S206 equipment and/or accessory device to the first coupling element.

The use of the terms “first”, “second”, “third” and “fourth”, “primary”, “secondary”, “tertiary” etc. does not imply any particular order, but are included to identify individual elements. Moreover, the use of the terms “first”, “second”, “third” and “fourth”, “primary”, “secondary”, “tertiary” etc. does not denote any order or importance, but rather the terms “first”, “second”, “third” and “fourth”, “primary”, “secondary”, “tertiary” etc. are used to distinguish one element from another. Note that the words “first”, “second”, “third” and “fourth”, “primary”, “secondary”, “tertiary” etc. are used here and elsewhere for labelling purposes only and are not intended to denote any specific spatial or temporal ordering. Furthermore, the labelling of a first element does not imply the presence of a second element and vice versa.

It is to be noted that the word "comprising" does not necessarily exclude the presence of other elements or steps than those listed.

It is to be noted that the words "a" or "an" preceding an element do not exclude the presence of a plurality of such elements. Although features have been shown and described, it will be understood that they are not intended to limit the claimed disclosure, and it will be made obvious to those skilled in the art that various changes and modifications may be made without departing from the scope of the claimed disclosure. The specification and drawings are, accordingly to be regarded in an illustrative rather than restrictive sense. The claimed disclosure is intended to cover all alternatives, modifications, and equivalents.
