The present invention provides in a second aspect, a method of storing a portable structure according to the present invention, the method comprising: providing the portable structure in an erected condition; folding the one or more sides in half, so as to gather a top of the side and a bottom of the side together and, in so doing, folding the one or more spacing members against resistance provided by the one or more spacing members to provide a flattened structure; coiling the resilient frame(s) against resistance provided by the resilient frame(s) by folding initially and then gathering in small coils or bends the resilient frame until all of the frame is gathered together; and thereby providing the portable structure in a stored condition.

In a further aspect, the present invention provides a method of erecting a portable structure according to the present invention, the method comprising: providing the portable structure in a stored condition; uncoiling I unbending the resilient frame by expanding the coils/bends under the influence of a returning force provided by the resilient frame; unfolding the one or more sides under the influence of a returning force provided by the one or more spacing means and providing in a spaced-relationship a top of the side from the bottom of the side; and thereby providing the portable structure in an erected condition.

Preferably, the resilient frame is coiled or gathered on itself in at least two turns.

In order that the invention may be fully disclosed, embodiments will now be described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is perspective view of a portable structure, according to the present invention; Figure 2 is a perspective view of a portable structure in the form of a paddling pool, according to the invention; Figure 3 is a perspective view of a portable water container, according to the invention; Figure 4 is a perspective view of a further embodiment of portable water container, according to the invention; Figure 5 is a perspective view of a portable ball pool, according to the invention; Figure 6 is a perspective view of a further embodiment of portable structure according to the present invention; Figure 7 is a perspective view of a portable play pen according to the present invention; and Figures 8A8A to SF are schematic views showing various states of operation of the portable structure of Figure 1 between erected and stored conditions.

Figure 1 shows a portable structure in an erected condition, indicated generally by reference 1, according to the present invention. In particular, the portable structure 1 has a circular cross-section at right angles to a vertical axis, the axis being shown by reference A. The portable structure 1 is provided by a base frame 2 (first resilient frame), a top frame 3 (second resilient frame), base panel 4, and side panels 5 (one or more sides).

The portable structure 1 in its broadest sense, therefore, defines an open-topped pot or container. The side panels 5 are provided with spacers 6 which ensure that the base frame 2 and the top frame 3 are provided in a spaced-relationship, as shown in Figure 1. The base frame 2 is continuous and made from coiled spring steel. It is located within a circular pocket, provided at the interface of the base panel 4 and the side panels 5, and is formed by material of the side panels and/or the base panel 4. Preferably, the pocket fully encloses the spring steel to provide an aesthetic aiuyiuiiL and also to prevent objects intertering with the base frame 2. The top frame 3 is also continuous and made from coiled spring steel and is provided within a circular pocket provided by material which makes up the side panels 5 and is, preferably again, fully enclosed by material for aesthetic and functional purposes. Both the base frame 2 and the top frame 3 are flexible and coilable / bendable.

The base frame 2 and the top frame 3 provide a two-dimensional shape to the top or base of the erected portable structure 1. As shown in Figure 1, the two-dimensional shape is circular. Both base frame 2 and top frame 3 are resilient. Four spacers 6 (spacing members) are provided for the invention shown in Figure 1 and are operable on the side panels 5. The spacers 6 provide a depth to the erected portable structure and, therefore, volume. The spacers 6 are made from coiled spring steel and extend in a relative axial direction with respect to the base panel 4 of the portable structure 1. The spacers 6 are provided to support and maintain the side panels 5, to prevent collapsing thereof. Further, the spacers 6 are foldable, typically in half so as to allow gathering of a top edge 7 and a bottom edge 8 of the side panel 5 together during the storing operation of the portable structure 1.

Preferably, the spacers 6 are equally spaced. Further, the spacers 6 are located within a longitudinal pocket, provided by material of the side panels, and can flex within those pockets to enable folding of the side panels 5.

Advantageously, the base frame 2 and top frame 3 are bendable and the spacers 6 are foldable from the erected condition of the portable structure 1, to allow the portable structure to adopt its stored condition wherein bending of the resilient frame and/or folding of the spacing members provides energy for moving the portable structure from the stored condition to the erected condition thereof.

The portable structure is preferably made from a suitable material that when used as a portable structure for the retention of liquids, the material does not allow liquid to leak. In particular, the base panel 4 and side panels may be made from numerous pieces of material.

Advantageously, the invention provides a portable structure 1 in which all of the components of the portable structure 1 are provided in both erected and stored conditions. Therefore, no assembly of the portable structure is required, merely an operating step to convert the portable structure -by uncoiling and unfolding, or coiling and folding -changes the portable structure between stored and erected conditions.

Figure 2 shows a portable structure 1 in the form of a structure 10. The pool is shown empty but may be preferably filled with water. Naturally, the materials chosen for the base panel 4 and side panels 5 are those that are both durable and waterproof. The pool is preliminarily designed for children. The pool 10 has all of the apparatus described in relation to Figure 1 and like references have been used to indicate common features.

Figure 3 shows a portable water container according to the present invention. In this form, the portable structure described in relation to Figure 1 is now provided as a portable water container 20. All of the features described in relation to Figure 1 are included and, therefore, like references have been utilised to show common features. In addition to the previous embodiments, the portable water container 20 is shown full of water 21. In particular, the portable structure 1 according to the present invention is suitable ror containing a large amount ot water up to tfle region of the top frame 3.

Figure 4 shows the embodiment of Figure 3 further including a partial cover 22. The cover 22 is provided with its own frame 23, located within a pocket provided by the material of the cover 22. The frame 23 provides a support for the material 24, creating a shade or cover for the portable water container 20. In this embodiment, the cover 22 is shown as an additional piece of apparatus. However, in some embodiments, the portable water container 20, or indeed any portable structure according to the present invention, may include an integral top or cover.

-10 -Preferably, the cover 22 may also be folded and or coiled for storage.

Figure 5 shows a further embodiment of portable structure, in this case the structure is a ball pool 30.

Again, this ball pool is based on the portable structure described in relation to Figure 1 and like references have been used to identify common features. Therefore, Figure 5 shows a portable structure of the present invention, used to form a ball pool. In particular, Figure 5 shows in more detail the pockets 6A surrounding at least part of the coiled spring steel 6B, which together provide the spacers 6. The ball pool may be filled with various balls to create a play pen or play house.

The one or more sides or side panels 5 provide depth to the container. Naturally, the depth of the container may be altered to suit the individual need of the particular use envisaged. In some contexts, it may be desirable to include a third (or subsequent) resilient frame to provide support and strength to a deeper container, or structure having highei walls as hoviu hi Liie eiubodimerit of Figure 6. In this embodiment a third resilient frame 3b is provided approximately midway between the base frame 2 and the top frame 3. The diameter of the third frame 3b is smaller than the base frame 2 and the diameter of the top frame 3 is smaller than the diameter of the third frame 3b resulting in a truncated shape to the portable structure 1. By truncating the shape of the portable structure towards a centre thereof, a more stable structure is provided, which is less likely to topple if weight is applied to the top of the side wall(s). The spacer members 6 run from the base frame 2 to the top frame 3. Each spacer member 6 may be formed from one piece of resilient material or may be formed -11 -from two pieces of resilient material joined to one another at or about the location of the third frame 3b.

Figure 7 depicts a further embodiment of portable structure according to the present invention in the form of a portable play pen 40. As with the embodiment of Figure 1, the structure comprises a base ring 2, top ring 3, side panels 4 and a base panel 4. In addition, the structure comprises a top panel 4b for forming a roof of the play pen and the side panels 5 have formed therein an entrance opening 41 allowing access for a child to enter and exit the interior of the play pen 41. The opening 41 is provided with curtains 42 which can be used to close the opening 41.

Preferably, the curtains 42 are formed from the same material as the side panels 5. The spacer members 6 are located in sewn pockets in the side panels 5. Erecting and collapsing the play pen works in the same manner as the previous embodiments.

Preferably, the structure_whether in the form of a portable water container, paddling pooi, play pen, ball OOi or similar can be manufactured fiin yitteiiCs 01 appropriate material. The segments may be welded or otherwise bonded together to form waterproof seals between respective segments. After construction of the material part of the structures, the resilient frame members and/or spacers may be inserted or otherwise connected to the material.

Figures 8A to 8F show schematic views of a method of storing the portable structures of the previous embodiments and is illustrated in particular with reference to the structure of Figure 1. Figure 8A shows the portable structure 1 in an erected condition. Figure 8F shows the portable structure 1 in a stored condition. Various states -12 -of operation during the storing/erecting procedure are shown in Figures SB through to 8E. Like references have been used to identify common features with respect to those features described in Figures 1 to 7. Starting from the erected condition shown in Figure BA, the side panels 5 are folded in half, so as to gather the top edge 7 of the side panel 5 and the bottom edge 8 of the side panel 5 together and, in so doing, folding the spacer 6 against resistance provided by that spacer 6, to provide a flattened structure 9, as shown in Figure 8B. The flattened structure 9 of 8B is then, initially, folded -as shown in Figure 8C -and then gathered in small coils, against resistance provided by the base frame 2 and top frame 3, until all of the frame 2,3 is coiled together, as shown in Figure BE. The coiled portable structure of Figure 8E is then again flattened to provide the stored condition of the portable structure -as shown in Figure 8F - and identified by reference 1'.

In reverse, and starting in the stored condition shown in Figure 8F, the coiled base frame 2 and top frame 3 must be uiioiied by expaxidixiy Liie coiis uxldeL Lhe iiifiueiie of the returning force provided by the base frame 2 and top frame 3 to return to their position provided in the erected condition. Uncoiling of the portable structure 1 is indicated in Figures 8D and BE until a flattened structure 9 shown in Figure BC is provided. As the spacers 6 wish to return to their original condition, the side panels 5 are then unfolded by releasing the grip which holds the top edge 7 and bottom edge 8 of the side panel 5 together and, under the influence of the stored force provided by the spacers 6, the erected condition of the portable structure 1 is thereby provided once more.

-13 -It will be understood by those skilled in the art that various materials may be used to provide material for the one or more sides, and top or base of the portable structure. Naturally, when the structure is intended for receiving water, then the material is waterproof. The material should also be durable and strong, to prevent inadvertent tearing during normal use. It will be understood that various materials may be chosen which provide the required strength, durability and waterproof characteristics, beyond those that are provided as examples.

The shape of the portable structure is defined by its cross-sectional-shape with respect to the axis A, shown in Figure 1. Naturally, in normal use, this axis A is a vertical axis, as the base of the portable structure is intended to be placed on the floor. Even when a top instead of a base is provided, the axis is still vertical. Further, the portable structure may have any cross-sectional shape, either regular or irregular, and still work in the same manner. In particular, when the cross-sectional-shape is circular, the pottable 5LULLUL-is considered to nave one, continuous side panel, for the avoidance of doubt. However, that is not to say that the side panel need be formed from only one piece of material. Naturally, the cross-sectional-shape dictates the number of side panels required.

Needless-to-say, the side panels and base panel may be provided by a number of pieces of appropriate material.

Further, the side and/or base panels may be provided by a combination of transparent, transluscent and/or opaque segement of material.

In an alternative, the water-containing portable structures of the present invention may include one or more sides which have one or more portions of a material having a -14 -density of less than water. These one or more portions are provided to help the sides float. In particular, the one or more portions of material may be provided at an upper edge of the one or more sides, remote from the base and/or may be provided in a spaced-relationship betweeen respective upper and lower edges of the one or more sides. The one or more portions of material have the effect of raising the one or more sides of the structure above the level of water contained within the structure -which helps to prevent any loss of water during use, filling or emptying.

Portable structures in the form of pools, water containers, play pens and ball pools have been described.

These structures are all provided when the portable structure is placed on a surface and when the base panel provides a bottom to a container defined by the side panels, i.e. an upwards-facing pot or container. However, the portable structure may be used inverted, and provide a playhouse having sides and a roof -provided by the top panel without the requirement for a material base.

In all embodiments of the inenticn, the opeiaLiiiy procedure to go between stored and erected conditions is simple and quick, and preferably does not require connection or otherwise of external features.
