Definitions
- the present invention relates to a multi-fuctional article of furniture.
- multi-fuctional articles of furniture i.e. articles of furniture which may adopt two or more configurations, each configuration adapted to use for a different respective purpose.
- futons are well-known, which may be configured either as a seat or as a bed.
- Multi-fuctional articles of furniture are also disclosed, for example, in US 4,925,245, US 5,772,101, US 6,367,874 and GB 2243543.
- the present invention aims to provide an improved multi-functional article of furniture, as elaborated below.
- an article of multi-functional furniture comprising a frame, the frame comprising: a bottom cross member; at least one upright member attached to the bottom cross member at one end thereof; at least one upright member rotatably mounted or hinged at an opposite end of the bottom cross member; and a top cross member releasably engagable with at least a portion of the rest of the frame.
- the article of furniture in accordance with the invention may be deployed in at least three different configurations: in a first configuration as a table; in a second configuration as a seat frame with a relatively horizontal seating surface and a relatively vertical backrest; and in a third configuration as a bed frame with a substantially horizontal surface of sufficient dimensions to support a human body when reclining.
- the terms "relatively horizontal” and “relatively vertical” as applied to the seating surface and backrest, respectively, of the seating configuration are intended to indicate the relative dispositions of the seating surface and backrest, rather than imply any absolute requirement that the seating surface be exactly horizontal or that the backrest be exactly vertical.
- the bed frame When arranged in the third configuration the bed frame, at least in embodiments intended for use by adults, will typically be at least 51 ⁇ 2 feet long, and preferably at least 6 feet long, and will typically be at least 2 feet wide, preferably at least about 21 ⁇ 2 feet wide.
- the top and bottom cross members will each typically be in the form of a square or rectangle, with at least first and second upright members joining the top and bottom cross members.
- at least one upright member (preferably two) is provided at one end or side of the cross members and a corresponding number of upright members is provided at the opposed end or side of the cross members.
- there four upright members arranged in two pairs, each pair being disposed towards opposed sides of the top and bottom cross members.
- the number and positioning of the bracing members will be the same for each pair of uprights.
- the upright or uprights at one end are preferably essentially fixedly attached to the bottom cross member (although in some embodiments they may be movably attached thereto) and the upright or uprights at the opposite end are rotatably mounted or hinged on the bottom cross member, so as to be allowed to rotate relative thereto to describe an arc through at least 90° and preferably through at least 170°, more preferably through at least 250° and typically through about 270°, such that in a preferred embodiment the rotatable upright or uprights can be laid substantially flat beneath the bottom cross member, or project outwards therefrom in substantially the same plane as the bottom cross member, or project upwards therefrom at an angle of approximately 90°.
- the uprights will typically be rectangular or square in section but may be, for example, triangular or right-angled in section or any other suitable shape.
- the top cross member is locatable on top of the upright members and typically releasably engages with the uprights and in such a location functions as a table top.
- the top cross member is however preferably readily releasable from such engagement, typically by a simple upward lifting movement, so as to be deployed in alternative positions, as explained elsewhere.
- an article of furniture in accordance with the invention presents a generally cube-like appearance (at least when in a table configuration).
- the frame may be comprised of wood or wood products (e.g. chipboard, plywood, fibreboard etc.), metal or synthetic plastics materials or any combination thereof.
- the bottom cross member comprises a plurality of depressions, recesses, apertures or grooves, as explained elsewhere. These may conveniently be provided by forming the bottom cross member with a plurality of slats with apertures between adjacent slats.
- the article of furniture further comprises a removable shelf member, which is preferably locatable between the upright members of the frame.
- the shelf member is locatable at a selected one of two or more different positions within the frame (e.g. at variable heights between the top and bottom cross members, so as to provide in the "table" configuration, a shelf at a variable height).
- the shelf member is preferably locatable in a storage position, so as to maximise a storage space defined within the frame between the top and bottom members and between the upright members.
- the shelf member is provided with a plurality of retaining members which releasably engage with or abut the frame.
- the retaining members comprise downwardly projecting flanges or ribs at opposed sides of the shelf, which engage or abut with a brace member provided between pairs of uprights and/or with the uprights themselves.
- a preferred optional component is a plurality of (preferably three) cushion pads, which are preferably connected or connectable by a flexible linkage.
- the flexible linkage may be reversibly rupturable e.g. comprising a zip fastening, press stud, or "Velcro" RTM or the like, or may alternatively simply comprise a flexible web of textile, fabric or the like, to form a folding cushion member.
- the cushion pads In a stowed configuration, the cushion pads may be positioned one above another and received within the storage space. Alternatively, the cushion pads may be removed from the storage space and used to provide cushion seating on the floor.
- a single, removable fabric cover may be provided for the folding cushion member, portions of which cover are engagable e.g. by means of a slide fastener, press studs or the like.
- the preferred embodiment described above may be deployed in any one of at least three configurations: table, seat, and bed.
- table table, seat, and bed.
- the arrangement of the various components in each of these configurations will now be described.
- the uprights of the frame are at substantially vertical positions, at approximate right angles to the bottom cross member, which may serve the function of a bottom or lowermost shelf of the table.
- the rotatably movable uprights are conveniently held in a substantially vertical position by releasable engaging means, such as a latch or a nut and bolt or similar.
- the top cross member provides the table top and is located on top of the uprights.
- the top cross member is removable from engagement with the frame, and the article can thus be deployed in a second table configuration, providing two separate tables: one (subsidiary) table has a top provided by the top cross member, the other (main) table may be formed by either: the remainder of the frame, with the removable shelf member in position acting as a table top; or, by inverting the remainder of the frame, such that the bottom cross member thereof becomes the top of the main table.
- the top cross member will desirably be provided with downwardly projectable legs. These may be, for example, fixed relative to the top cross member and shaped and positioned so as to abut the inner surfaces of the upright members of the frame; or may be retractably, rotatably or foldably mounted on the top cross member, being located in a retracted or folded position when the top cross member is situated on top of the uprights, but being positionable in a lowered or deployed position when the top cross member is used in its separate table function.
- a locking or retaining means is provided to lock the retractable, rotatable or foldable legs in the retracted/folded position and the same or a different locking or retaining means is provided to lock the legs in the lowered or deployed position, as desired.
- the top cross member In order to alter the configuration of the article of furniture from table to chair, the top cross member must be removed from the frame.
- the rotatably mounted uprights may then be rotated inwards through approximately 90° or, more preferably, rotated outwards through approximately 270°, such that the uprights assume a generally horizontal position essentially parallel with the bottom cross member of the frame and (preferably) located below the bottom cross member.
- the bottom cross member and/or the folded uprights (with any associated bracing members) provide a relatively horizontal seating surface.
- the other uprights and any associated bracing members may provide a relatively vertical backrest for the seat frame. More preferably, however, a further component is positioned against the other uprights, so as to provide an angled (but relatively vertical) backrest and more comfortable support.
- the further component may comprise that which is the top cross member in the table configuration.
- the top cross member is deployed in its separate subsidiary table mode, and the angled (relatively vertical) backrest is instead provided by the removable shelf member.
- a bottom edge of at least one of the downward projecting flanges or ribs engages with a depression, recess, aperture or groove provided on the bottom cross member of the frame, which engagement serves to retain the shelf member in a particular position when functioning as a backrest and/or holds the shelf member above the floor.
- a plurality of such depressions, recesses, apertures or grooves are provided on the bottom cross member, located generally parallel to, but at different distances from, the fixed uprights, such that by locating a bottom edge, flange or rib of the shelf member in a selected one of the plurality of depressions, recesses, apertures or grooves, and by resting an upper portion of the shelf member against the (preferably) fixed pair of uprights and/or a brace member provided therebetween, the rake of the backrest my be adjusted.
- the cushion pads are arranged on the seat frame.
- the cushion pads are provided as a folding cushion member, part of the cushion member is located against the backrest and the rest (typically the majority) of the cushion member is provided on the relatively horizontal seating surface.
- the removable shelf member (acting as the relatively vertical backrest) is removed and, if positioned on the floor, can act as a low-level bedside surface.
- the ribs which act as retaining members in the shelf or backrest modes, are now able to act as short legs to raise the shelf member off the floor.
- the rotatably mounted uprights are rotated to a substantially horizontal position, extending outwards from the bottom cross member.
- the top cross member is then releasably attached to the ends of the rotatably mounted uprights and/or a bracing member provided therebetween, such that the article of furniture now presents a bed frame with a substantially horizontal surface (composed of the bottom cross member; the rotatably mounted uprights rotated into a horizontal position, together with any associated bracing members; and the top cross member) of sufficient dimensions to support a human body when reclining.
- the other pair of uprights and their associated bracing members form a headboard.
- the cushion pads are placed on top of the bed frame.
- the article of furniture is provided with releasable engagement means such that, in at least one (and preferably more than one) configuration the article of furniture may be releasably engaged with at least one further article of furniture in accordance with the invention.
- the two or more articles so releasably engaged will be arranged side by side in the same configuration, but may alternatively be arranged in different configurations (e.g. one as a table and one as a chair; or one as a table between two articles in the chair configuration and so on).
- the releasable engagement means comprises one or more brackets on each side of the article.
- an aticle of furniture in accordance with the invention will typically comprise one or more male bracket members on one side of the frame (conveniently provided on the uprights) and the same number of female bracket members in a corresponding position on the other side of the frame, the male bracket members comprising a projecting pin, knob or the like receivable and retainable by the female bracket members on another article of furniture according to the invention.
- FIG. 1 A preferred embodiment of an article of furniture in accordance with the invention is shown in Figure 1 and comprises a four-sided wooden frame of generally cuboidal shape, comprising a bottom cross member 2, first 4a, b and second 6a, b pairs of uprights (only one of the first pair of uprights can be seen in Figure 1A), and a top cross member 8.
- the article In its table configuration, the article has dimensions of about 19 inches in height, 31 inches in width, and 36 inches in length.
- the bottom cross member comprises five horizontal wooden slats (one of which is denoted by reference numeral 10) joined at their opposed ends to transverse supports (one of which is denoted by reference numeral 12).
- first pair of wooden uprights 4a, b which are (preferably) rigidly fixed to the cross member 2 in a substantially vertical position.
- a pair of substantially horizontal bracing members 14, 14' is provided between the members of the first pair of uprights.
- a second pair of wooden uprights 6a, b which are rotatably mounted on the bottom cross member 2 so as to allow for rotation about the bottom cross member through an arc of at least about 250°, preferably through about 270 .
- a pair of horizontal bracing members 16, 16' is provided between the members of the second pair of uprights, at a position which corresponds to that of the bracing members 14, 14' provided between the members of the first pair of uprights.
- a hinge 15, about which upright 6b can rotate, is shown.
- the arrangement is such that the rectangular, nearly square, bottom cross member 2 is held in a generally horizontal position, a little above the floor or other supporting surface upon which the article is placed, by the two pairs of uprights, with one upright at each of the four corner regions of the bottom cross member.
- a top cross member 8 is located on top of the uprights.
- the top cross member 8 comprises a sheet of medium density fibreboard (MDF), plywood, wood, synthetic plastics material or similar, of generally similar dimensions to those of the bottom cross member 2.
- MDF medium density fibreboard
- the top cross member 8 may however easily be removed from the frame by a simple upward lifting movement. If desired, additional releasable attachment means (e.g. nuts and bolts, screws or the like) may be provided to attach the top cross member to the uprights and/or bracing members.
- a storage space indicated generally in Figure 1 by reference numeral 26.
- This may be occupied, for example, by a folding cushion member, comprising a foldable chain of three cushion pads, adjacent pads being flexibly linked together by a web of textile material.
- the folding cushion member may be removed from the storage space and use as a pouffe cushion, or in other configuration, to provide a seating area.
- the exemplified embodiment additionally comprises a removable shelf member 28, comprising a generally flattened sheet of metallic material, synthetic plastics material, wood or similar, of generally similar size and shape as the top cross member.
- the removable shelf member When the folding cushion member is located within the storage space, the removable shelf member may be stowed in a storage position (typically, resting on or just above the bottom cross member, as in Figure 1A, or on or just above the folding cushion member). However when the folding cushion member is removed, the shelf member 28 may be deployed as a shelf, the height of which may be adjusted between at least an upper and lower position. In the upper position the shelf member 28 is supported by the uppermost horizontal 14, 16 bracing members, whilst in the lower position the shelf member 28 is supported by the lowermost bracing members 14, 16.
- Figure 4 shows the article of furniture with the top cross member 2 removed and the shelf member 28 deployed in its lower shelf position.
- Figure 1B is a sectional view of the article shown in Figure 1A.
- the Figure shows the article in the table configuration with a removable shelf member in the storage position 28 and also in an alternative upper shelf position 28'.
- downward projecting ribs 30a, b 32a, b on the underside of the shelf member 28 are located in apertures between adjacent slats 10 of the bottom cross member.
- the shelf member is rotated 90° relative to the storage position.
- the shelf member rests on top of bracing members 14' and 16' and the longer ribs abut the bracing members.
- the shelf member abuts the inside of the uprights, such that the shelf member resists translational movement in the horizontal plane.
- each pair of ribs comprises one 'long' rib (30b, 32b) and one 'fat' rib (30a, 32a). The longer ribs are adjacent to, but inside, the 'fat' ribs.
- top cross member 8 may be readily removed from the rest of the frame and used as a separate, subsidiary table, e.g. as shown in Figure 6.
- the rest of the frame can continue to be used as a main table, either with the removable shelf member 28 acting as the table top, or by inverting the frame and using the under-side of the bottom cross member 2 as the table top.
- the top cross member 8 is provided with two pairs of foldable or otherwise retractable legs. These are best seen in Figures 2A-2D. As shown in Figures 2A and 2D, legs 34 a, b are attached to cross piece 36 which is hingably mounted on the underside of top cross member 8, and legs 38a, b are attached to cross piece 40 which is similarly hingably mounted on the underside of the top cross member 8.
- the pairs of legs 34a, b, 36a, b are mounted to the lower surface of the cross member 8 so as to allow for limited rotation of the legs, such that the legs may be rotated downwards through about 90 for deployment or rotated upwards out of the way, resting flush against the underside of the top cross member when it is attached to the rest of the frame.
- Four rotatable catches 42 are provided to lock the legs in their downward position when the top cross member 8 is deployed as subsidiary table, and two similar rotatable catches 44 are provided to retain the legs in their folded position when the top cross member is attached to the rest of the frame in the table configuration.
- the exemplified article of furniture in accordance with the invention may be deployed in a chair configuration, as illustrated in Figure 7.
- the procedure is as follows. Firstly the top cross member 8 must be removed from the top of the frame.
- the rotatably mounted pair of uprights 6a, b may then be rotated outwards through approximately 270°, such that the pair of uprights assume a generally horizontal position essentially parallel with the bottom cross member 2 of the frame and located below the bottom cross member.
- the bottom cross member 2 and/or the folded uprights 6a, b (with associated bracing members 16, 16') provide a relatively horizontal seating surface.
- the (preferably) fixed pair of uprights 4a, b and associated bracing members 14, 14' may be used provide a relatively vertical backrest for the seat frame. More preferably the relatively vertical (but angled) backrest is instead provided by the removable shelf member 28.
- Figure 8 is a perspective view of the rear part of the article of furniture in the chair configuration and Figure 9 is a sectional view of the same part of the chair with the cushions omitted.
- the shelf member 28 and the longer ribs 30b, 32b are received in the aperture between adjacent slats 10 of the bottom cross member 2.
- the 'fat' ribs 30a, 32a engage with end base slat 10 and stop the shelf member 28 sliding entirely through the aperture.
- the 'fat' ribs 30a, 32a contact the uppermost edge of bracing member 14' and therefore, in conjunction with the engagement between shelf member 28 and slats 10, hold the entire arrangement at a convenient angle to the vertical, providing a comfortable back rest.
- the cushion pads are arranged on the seat frame.
- the cushion pads are provided as a folding cushion member
- part of the cushion member is located against the backrest and the rest (typically the majority) of the cushion member is provided on the relatively horizontal seating surface.
- the shelf member 28 is positioned with the ribs 30a,b 32a,b facing forwards (i.e. towards the relatively horizontal seating surface). In this way, when a cushion is placed against the backrest, the ribs impart a degree of concave curvature to the cushion, for greater comfort, when a person sits leaning against the backrest.
- the top cross member 8 may be used in its separate table mode.
- the exemplified article of furniture in accordance with the invention may also be deployed in a bed configuration, as illustrated in Figure 10.
- the procedure is as follows: the removable shelf member 28 (acting as the relatively vertical backrest) is removed and, if positioned on the floor, can act as a low-level bedside surface.
- the rotatably mounted pair of uprights 6a, b is rotated to a substantially horizontal position, extending outwards from the bottom cross member 2, at approximately 180° to their position in the chair configuration.
- the top cross member 8 is then releasably engaged with the ends of the rotatably mounted uprights such that the article of furniture now presents a bed frame with a substantially horizontal surface (composed of the bottom cross member; the rotatably mounted uprights rotated into a horizontal position, together with any associated bracing members; and the top cross member) of sufficient dimensions to support a human body when reclining.
- the (preferably) fixed pair of uprights 4a, b and their associated bracing members 14, 14' form a headboard.
- the cushion pads are placed on top of the bed frame.
- the exemplified embodiment is shaped and dimensioned such that, in a number of configurations, all or part of the article can be releasably engaged with all or part of an identical article of furniture in accordance with the invention.
- two or more articles of furniture in the chair configuration may be releasably coupled to form an extended seating area, akin to a sofa.
- two or more articles in the chair configuration may be attached to one or more articles in the table configuration, to form a combined seating and table area.
- male and female bracket members are provided on one side of the article and one or more female bracket membes are provided on the opposite side of the article, such that identical articles of furniture in accordance with the invention may be releasably engaged side-by-side, the male bracket(s) on the side of one article engaging with the female bracket(s) on the side of an adjacent article.
- two male brackets are provided, one on a fixed upright and one on the front, rotatably mounted upright, and female brackets are provided in the corresponding position on the other side of the article.
- the male bracket will typically comprise a projecting member such as a pin, knob or the like, and the female bracket will comprise an aperture, groove, slot or similar, shaped and dimensioned to receive and retain the projecting member of the male bracket.
- the brackets will typically comprise or consist of metal and/or synthetic plastics material, especially an injection moulded plastics material.
- a typical male bracket is 40 illustrated in Figure 12.
- a typical female bracket 42 for attachment to the fixed upright is illustrated in Figure 13.
- a typical female bracket 44 for attachment to the rotatably mounted upright is illustrated in Figure 14 - the depicted brackets allow for one or both articles of furniture to be configured in any of the table, chair or bed configurations, and still be releasably engaged with an adjacent article of furniture - the front fittings of the articles may be simply disengaged, the rotatably mounted uprights rotated to their desired position, and then re-engaged via the transverse slot in the female bracket.
- the dimensions marked 'A' and 'B' essentially correspond (allowing for operating clearance) to the dimensons 'A' and 'B' denoted in Figure 14.
- the dimensions of the exemplified embodiment of the invention are amenable to limited enlargement or reduction, within reasonable bounds.
- the inventor explicitly envisages a smaller-sized version of the article, reduced in dimension by about 20 % suitable, and specifically intended, for use by children.
