Description

FIELD OF THE INVENTION

The present invention relates to flexible furniture components and methods of making such components.

DESCRIPTION OF THE PRIOR ART

Furniture is a staple product used in domestic, working and public environments. Furniture may be used to facilitate the use of space, such as in a seat or table, or to divide space, such as in a partition. By way of example, partitions are frequently used to subdivide spaces, or to create more intimate spaces. Typically such partitions are rigid, or have rigid frames, or are formed from rigid interconnected panels and they are relatively large, heavy, and cumbersome, and therefore difficult to set-up, take down, store, and transport. Similarly other items of furniture, such as seating structures, are typically of a rigid, or permanent nature that, at most, are moveable to alternative locations.

Moreover, the inherent rigidity of such items of furniture limits the extent to which they can be dynamically resized (extended or contracted) and reshaped to suit varying spaces and requirements, or readily moved around for relocation, or storage.

Additionally, such furniture items, particularly in the form of partitions are typically formed from opaque panels which inhibit the transmission of light, therefore necessitating increased use of, or rearrangement of artificial lighting to restore adequate lighting levels.

In domestic, working, and public environments it is frequently desirable to be able to subdivide and reshape space on a temporary basis. For example, visitors may require a temporary sitting or sleeping area, office workers may need to convert an open plan area into subdivided working space or temporary meeting space, trade show participants may need to demarcate a temporary display area, and designers may need to create and shape a temporary area for an event, or a backdrop for a designed area, such as in a window display in a retail setting, in a showroom, or in a theatrical setting. For these types of applications, furniture components that are rigid, heavy, and/or cumbersome may be costly to transport, difficult to set up/take down, and may require significant storage space. Furniture in the form of a partition that is rigid will also place significant constraints on the ways in which a given space can be partitioned, limiting its functionality, and a partition that is fully opaque will severely disturb natural lighting.

It is therefore an object of the present invention to provide articles of furniture in which the above disadvantages are obviated or mitigated.

SUMMARY OF THE INVENTION

According therefore to one aspect of the present invention there is provided an article of furniture having a core formed from a plurality of laminar panels of a flexible flaccid material. Each panel has a pair of oppositely-directed major faces with faces of adjacent panels being inter-connected to provide a cellular structure upon movement of the faces away from each other. A respective one of a pair of supports is provided at opposite ends of the core and connected to respective ones of the faces. The supports are self-supporting to provide rigidity to the article of furniture and/or to provide connectivity between like articles of furniture. In this way, the supports may be moved apart to expand the cellular structure and extend the overall length of the article of furniture, and/or be used to connect any of more than one of such articles together in series.

DETAILED DESCRIPTION OF THE INVENTION

Referring therefore to FIG. 1, a partition 10 comprises a core 12 and a pair of supports 14, 16 at opposite ends of the core 12. As can best be seen from FIGS. 2 and 3, the core 12 is formed from a plurality of panels 18. The panels 18 each have a pair of oppositely-directed major faces 19, 20, and are formed from a flexible flaccid material. In the preferred embodiment, the material forming the panels 18 is standard white, flame retardant tissue paper, having a weight of approximately 13.5 lbs (500 sheets @ 24″×36″=13.5 lbs). Each panel has a major dimension or height h and a width w which may be adjusted to suit particular environments. Typically the height will be in the order of 1-2 metres but could range from 0.5-3 metres when used as a partition, or 0.1 metres to 0.5 metres when used as a seat. A seat height of 0.45 m has been found particularly beneficial. The width is typically in the order of 30 centimetres but could range from 10-100 centimetres. Adjacent panels 18 are inter-connected to one another at spaced intervals that alternate across the width of the face of the panel 18. As indicated in FIG. 2, the connection between panels 18a and 18b is through a series of parallel, laterally-spaced strips 24 on the face 19 of panel 18b. The strips 24 are defined by stripes of adhesive, which connects the panels 18a, 18b to one another, as shown in FIG. 3.

Similarly, the inter-connection between a panel 18b and 18c is through spaced parallel strips 28 on the face 19 of panel 18c which are offset from the strips 24. Each of the panels 18 is therefore alternately connected to the panel 18 on opposite sides so that, as shown in FIG. 3, upon extension of the panel in a horizontal direction, a cellular structure having voids 30 is formed within the core. The voids 30 extend vertically from top to bottom of the core 12 with the panels 18 providing a continuous transverse barrier. The lateral outer ends of each of the panels 18 are connected so as to form vertical pleats on the exterior faces of the core 12.

An end panel 18d of the core is connected to respective ones of the supports 14 and 16 over its entire width. The supports 14 and 16 are made from a self-supporting material, typically a non woven felt material, which has a degree of flexibility but also has sufficient rigidity to resist collapse of the core 12. In a typical application, the felt is a 1.95 nominal pounds per square yard felt having a thickness in the order of 3 millimetres, although other weights and thicknesses may be utilized as appropriate depending upon the overall dimensions of the partition 10. The supports 14 and 16 extend laterally beyond the core as indicated at 32 and are adhered to respective ones of the end panels 18d.

Fasteners in the form of a pair of loop and hook strips 34, such as that sold under the trade name “Velcro” are stitched to the felt supports 14 and 16, and extend vertically from one end to the other.

The core 12 is collapsible so that the major faces of adjacent panels 18 lay parallel to one another and in abutment. In this position, as shown in FIG. 4a, the partition 10 may be stored in a flat, collapsed position. When the partition 10 is required, it can be oriented vertically (FIG. 4b) and the opposite supports 14 and 16 used to manipulate the partition. The supports 14 and 16 are moved away from one another as shown in FIG. 4c to expand the core so that the cellular structure is opened within the core 12. The lateral extension of the supports 14, 16 beyond the core 12 provides marginal tabs that may be grasped to facilitate manipulation of the core without direct contact with the panels 18.

Once partially extended, the supports 14 and 16 may be folded along a vertical axis to provide enhanced rigidity at each end of the partition 12. This may be seen in more detail in FIG. 5 where it will be seen that the opposite edges of the supports 14 and 16 may be brought together so that the loop and hook strips 34 are brought into abutment. The loop and hook strips 34 engage one another and thus hold the support in a folded tubular configuration. This movement is accommodated by the flexible nature of the cellular structure which expands towards the lateral edges to accommodate the folding of the supports 14 and 16. With the supports 14 and 16 folded into a tubular support, extension of the core 12 continues as shown in view (e) of FIG. 4, until the desired overall length is reached.

With the partition 10 expanded, it has sufficient width to remain stable in a vertical position with the rigidity provided by the end supports 14 and 16. The material forming the panels 18 is preferably translucent so that a pleasing transmission of light through the panel may occur, while still providing a degree of privacy.

The extended partition as shown in FIG. 4e may be adjusted to different configurations as illustrated by the open curve shown in FIG. 1 and the wrapped curve shown in FIG. 8. The core 12 has a surprising degree of flexibility to accommodate different configurations and allow an appropriate shaped and sized partition to be installed in an otherwise open space. By varying the overall dimensions, additional functionality may be obtained. The extended partition shown in FIG. 4e may also be made with a lower height, for example 1 metre and a wider base, for example 0.5 metres so that the top surface of the partition may be used as an area to display objects. Such an arrangement is illustrated in FIG. 9. Where appropriate, the terminal portions of the voids 30 may be used as a pocket to support a container, such as a vase, or similar object. In this embodiment, the height would be between 0.5 and 1.5 metres.

The provision of the supports 14 and 16 also permits a pair of partitions 10 to be joined end-to-end as shown in FIG. 6. As may be seen from FIG. 6a, a pair of partitions 10 is erected and positioned with supports 14, 16 at opposite ends of each partition adjacent one another. The loop and hook strips 34 in adjacent supports 14, 16 are then brought into contact with one another as shown in FIG. 7 so that the partitions 10 are joined in seriatim. The additional thickness provided by the double support at the intersection enhances rigidity, with the supports 14, 16, at the free ends of the partition being folded upon themselves to provide stable support.

After use of the partition 10, it is simply necessary to reverse the procedure by moving the ends towards one another, unfolding the supports 14 and 16, and collapsing the core 12 to its minimum size. It may then be stored and used when subsequently required.

In the above embodiments, the core has been made from a light weight paper material, although it will be apparent that alternative materials may be used that fulfil the same functional requirements. For example, it is possible to utilize a heavier weight paper material, such as Kraft paper, or a non-woven textile material such as a plastic material known as Tyvek from DuPont which is both tear and water resistant. Alternatively, a paper laminated with a plastic film to provide a composite material may be used. With such a core material, the supports 14 may be made of a felt or may be made from a material similar to the core material but with increased thickness. The felt used in the support would be sufficiently flexible to allow folding to define the tubular support structure at each end with fasteners such as the loop and hook strips 34 incorporated on the support. In some applications, the inherent stiffness of the material used in the core is such as to provide sufficient rigidity to the core when the cellular structure is expanded for the core to be self supporting when expanded. Kraft paper or plastics material has provided sufficient rigidity for this purpose. In this case the supports may be provided to permit connectivity if multiple units are to be joined end to end.

Whilst a translucent material is preferred, it will be apparent that opaque or different coloured materials may also be utilized. The dimensions of the void 30 and the number of voids in the lateral direction may be adjusted to suit particular applications. It has been found in practise that a spacing between stripes 24, 28 in the order of 5-10 centimetres (when unexpanded) is appropriate, although spacing as low as 1 cm. may be used, and that the width of the stripes 24, 28 is between 1 and 10 millimetres. This arrangement provides a flexible structure with extensive elongation to provide maximum functionality.

An alternative form of connection for articles of flexible furniture is shown in FIG. 10-12, in which like reference numerals will be used to denote like components with a prefix 1 added for clarity. In the embodiment of FIG. 10, a pair of partitions 110 are arranged to be joined end-to-end in a manner similar to that shown in FIG. 6. The end panel 118d of the core 112 is secured to supports 114, 116. The supports 114, 116 are made from a self-supporting material, which in this embodiment are preferably made from a rigid material such as a millboard. The supports 114, 116 lay within the periphery of the end panel 118d so that the end panels 118d overlap by a margin in the order of 20 millimetres around the millboard.

Each of the supports 114, 116 has a series of holes 140, best seen in FIG. 11 formed through the millboard. The holes are arranged in a regular pattern, as will be described more fully below with respect to FIG. 13, and are arranged to receive rare earth magnets 142. The magnets 142 are typically in the order of 3 millimetres thick and 25 millimetres diameter. The magnets are a tight sliding fit in the holes 140 so as to be frictionally retained by the millboard. The millboard itself is chosen to be of the same thickness as the magnet 142 so that the face of the magnet 142 is flush with the surface of the millboard.

The magnets 142 ate oriented such that a common polarity is present for all magnets on one face. Thus the magnets in the support 114 shown in FIG. 10 are oriented such that the north pole is exposed and those of the support 116 in the adjacent partition 110 are arranged such that a south pole is exposed. The exposed end face of the millboard is wrapped by a cover 144 of the same material as used to produce the core 112 for aesthetic purposes and to retain the magnets in situ. The cover 144 extends over the edges and each face of the millboard to provide self contained end supports 114, 116 to facilitate manufacture as well as enhance the aesthetics.

With the magnets in situ, the partitions 110 may be connected to one another by relying upon the magnetic attraction between the opposite poles of adjacent partition. The rare earth magnets 142 have sufficient force to retain the supports 114, 116 in abutment with one another. However the supports may be readily separated by sliding the partitions relative to one another or pulling them apart axially to release the magnets. The margin of the end panel 118d provides a flexible tab to permit manipulation of the core 112.

As can be seen in FIG. 13, the arrangement of magnets 142 on the support 114, 116 provides a grid that allows different size partitions to be connected in seriatim. The magnets 142 are arranged in two columns in rows uniformly spaced such that a relatively tall partition may be attached to a relatively small partition with the magnets 142 in alignment. The grid also allows partitions to be stacked on top of one another and connected in seriatim to a taller partition to form a continuous wall.

Whilst it is convenient that the supports 114, 116 are formed from rigid millboard to carry the magnets, it will also be apparent that a similar arrangement may be achieved using the self-supporting flexible supports 114, 116 such as the felt shown in the embodiments of FIGS. 1 through 9. The end panel 118d and the covering panel 144 secures the magnets 142 within the flexible support 114, 116 so as to be retained within the hole 140. This arrangement would also allow the end panels to be folded as shown in FIG. 5 provided that the orientation of the magnets is such that one column has a north polarity and the other column has a south polarity. A complimentary arrangement on the support of an adjacent partition will still permit the partitions to be joined to one another in seriatim as well as folded.

The embodiments are described above in the context of a partition. However, the ability to dimensionally resize the core 12 provides for its use in alternative articles of flexible furniture, such as those shown in FIGS. 14 through 17. In the embodiment of FIG. 14, a circular seat 210 is provided having a concave upper surface 211. As seen in FIG. 15, the lower surface 213 of the core 212 is planar to sit against the floor and the upper and side surfaces smoothly curved. The opposite end faces 218d of the core are secured to supports 214, 216 that carry a series of magnets 242. The magnets are wrapped by a cover 244 of the material used to form the core to provide a pleasing aesthetic as well as secure the magnets 242 within the supports 214, 216. The seat 210 may be stored in a collapsed flat position and when needed expanded into a circular array with the supports 214, 216 in abutment. The magnets 242 secure the supports 214, 216 to one another and hold the core 212 in the circular configuration presenting an upper concave surface 211. For storage, the supports are separated and the core collapsed to a flat configuration.

As shown in FIG. 14, the seat 210 is formed from three cores 212 joined end to end to make a torus. It will be apparent that the overall diameter of the seat 210 may be increased by expanding the inner diameter of the torus and thereby further expanding the cores 212. Alternatively, a single core 212 may be used with the supports 214,216 connected to one another, provided there are sufficient laminated panels to permit extension of the core over the required circumference. In this case, the diameter will be similar to that shown in FIG. 14.

A simple seat may be provided in a similar manner by having an expanded core 212 with a planar upper surface 211, arranged either in a cylindrical form with supports 214, 216 in abutment, or in the form of a bench with said supports not in abutment. In each case, multiple units may be joined end to end to increase the diameter of the cylindrical seat, or the length of the bench, which can be arranged linearly, or in an undulating manner, and which can act as a form of partition, as shown in FIGS. 1 to 9, and may be stacked one on top of the other to increase the overall height.

When used in a seating embodiment, the dimensions of the cellular structure and the stiffness of the material used is adjusted to provide an increased structural rigidity and increased weight bearing capacity, kraft paper has been found to have the requisite properties and it has been found preferable to reduce the spacing between the glue stripes to 2.5 cm so that the maximum dimension of each void 30 in a collapsed state is 5 cm.

A similar arrangement of flexible furniture is used with respect to a light as shown in FIGS. 16 and 17 in which like reference numerals will be used to denote like components with a prefix 3 for clarity. In the embodiments of FIGS. 16 and 17, a light 310 is formed with a core 312 with end panels 318d secured to respective supports 314, 316. In this arrangement the axis of the voids is radial although an axial orientation may be used if preferred. The supports, as shown in FIG. 17, carry an array of magnets 342 so that the supports may be joined to one another as described above. A bulb 350 is located within the centre chimney formed by the fanning of the core 312. The bulb 350 illuminates the core 312 to provide a pleasing effect and the heat may escape through the central aperture provided by the core. Naturally the core is formed from a fire-resistant material, or the light source produces only a small amount of heat. The light 310 may be collapsed and stored in a flat configuration and deployed as required in different locations.

It will be apparent from the various embodiments described above that the provision of the cellular structure to foam the core and the releasable fastenings provided at the end panels allow for a variety of configurations to be provided. The provision of the magnets or other fasteners in a pre-defined grid permits different components to be joined to one another to increase a variety of configurations that may be utilized. As indicated above, the dimensions of the core may be adjusted to suit particular requirements, ranging from a single row of voids to provide a thin or narrow partition, to a relatively wide cellular structure with multiple rows of voids to provide seating or table like surfaces.

Although the invention has been described with reference to certain specific embodiments, various modifications thereof will be apparent to those skilled in the art without departing from the spirit and scope of the invention as outlined in the claims appended hereto. The entire disclosures of all references recited above are incorporated herein by reference.
