At least one foldable support leg (38, 40) is provided on the displaceable panel (16), a leg (38, 40) being comprised of at least two sections (38.1, 38.2 and 40.1, 40.2) hingedly connected together at a hinge point (42, 44) intermediate of its two extreme ends. The one extreme end is pivotally secured (46, 48) to the displaceable panel (16) and the other extreme end is pivotally secured (50, 52, 76, 78) to a stationary part of the article. In the open position the panel (16) is supported on the foldable legs (38, 40).

Description: THIS INVENTION relates to an article of furniture. More particularly the invention relates to a versatile and utilitarian article of furniture intended to be used as a storage cabinet, desk, computer work station, book case, liquor cabinet, cabinet for a sewing machine, food processor or similar appliance, and for many other useful purposes. GB 2 222 365A discloses an article of furniture defining an enclosed space having a floor or shelf 20 and a door 22. The door 22 is hinged along a bottom edge thereof to a front edge of the shelf 20. The door is pivotal into an upright orientation to close the space, and into a horizontal orientation generally co-planar with the shelf 20 to form an extension of the shelf. The article of furniture has auxiliary legs in the form of supports 42. The supports 42 are respectively hinged to bottoms of angled sides 16. When the door 22 is closed, the supports 42 are hinged against to extend adjacent and along the angled sides 16 in an inoperative orientation. When the door 22 is opened, the supports 42 are pivoted away from the angled sides to support the door 22 on free upper ends of the supports 42. GB 2 054 354A discloses a piece of fold-away furniture. It folds against a wall in a stowed condition and unfolds to provide a table top and two benches extending alongside the table top. Each bench has a stationary, upright leg 11 fixed to the wall. A seat portion 10 of the bench is hinged at one end to a top of the fixed leg 11. Toward an opposed free end of the seat portion, a foldable leg 12 is pivoted. A rigid aluminium spar is hinged at opposed ends to the legs 11, 12. When the seat portion 10 is folded, it extends, in series, in co-planar fashion, with the fixed leg 11. The leg 12 and the spar 13 extend in flat configuration against the seat portion 10. When the seat portion 10 is unfolded, it hinges from the fixed leg 11. The spar 13 causes the leg 12 to open by pivoting relative to the seat portion 11 to support the seat portion towards its free end. According to the invention, there is provided an article of furniture including a support structure; a wall having an horizontally disposed support surface and mounted on the support structure; a displaceable panel which is hinged to be pivotal between an upright, closed condition in which it obscures the support surface and an open condition in which it extends substantially horizontally and level with the support surface; at least one support leg which is pivotal between an inoperative condition, and an operative condition in which it is arranged to support the displaceable panel when it is in its open condition, characterized in that the at least one support leg includes two sections which are hinged together toward adjacent ends of the sections, opposed extreme ends of the sections being hinged respectively to the displaceable panel toward a free end thereof and to the support structure, the arrangement of the support leg being such that when the displaceable panel is in its closed condition, the support leg extends in generally straight configuration, and when the displaceable panel is in its open condition, one section extends downwardly from the displaceable panel to support it, and the other section extends from the support structure transversely to the one section to locate it against the support structure; and in that the article of furniture includes at least one platform displaceably mounted on the support surface to be displaceable from a retracted condition over the support surface to an extended condition on the displaceable panel when the displaceable panel is in its open condition. Two laterally spaced foldable support legs may advantageously be provided to support the displaceable panel at either end when it is in its open condition. In one embodiment of the article of furniture, said at least one platform may include at least one slide track in the form of a groove in its underside, and the article of furniture may include a stop means in the form of a button on the support surface which button is arranged to co-operate with the groove to limit the extent of sliding. In another embodiment of the article of furniture, said at least one platform may be pivoted at an a-symmetric position on the support surface and may be pivotal between the retracted condition and the extended condition. Said at least one platform may be adapted to support a sewing machine. Instead, said at least one platform may be adapted to support a computer work station. When the foldable support leg is in the straightened condition it may conveniently be arranged snugly adjacent an outer face of the article, to present a neat appearance. The article may include a closable cabinet having opposed top and bottom walls and upright side walls to define an enclosed space. The bottom wall of the closable cabinet may preferably constitute the horizontally disposed support surface, and an upright wall of the cabinet, preferably the front wall of the cabinet, may constitute the displaceable panel. The front wall may thus be displaceable from an upright closed position in which it closes the cabinet, to an open position in which it is disposed in a substantially horizontal position coplanar with the support surface provided by the bottom wall. The displaceable wall may thus be mounted on the unit in such a manner that when it is in the open position, it will be disposed substantially coplanar with the support surface in the cabinet, so as to provide an extended or enlarged working surface. As indicated above, the support surface in the cabinet may be provided by the bottom wall of the cabinet. In use, the area of the extended or enlarged working surface will comprise the total of the area of the support surface and the area of the displaceable wall. The cabinet may have a six-sided rectangular configuration, in use having rectangular spaced and parallel top and bottom walls, rectangular spaced and parallel upright rear and front walls, and a pair of rectangular spaced and parallel upright side walls. As indicated above, the upright front wall may conveniently be the displaceable wall. The front wall constituting the displaceable panel may be hingedly mounted on the bottom wall along its lower edge, to permit pivotal displacement of the front wall around an axis extending substantially parallel to its lower edge, its three other sides not being secured to the side and top walls, the arrangement being such that it can be displaced pivotally from an upright closed position, in which its three unsecured edges are located adjacent the side and top walls so that it closes the cabinet, to an open position in which it is disposed substantially horizontal and coplanar with the bottom wall to constitute with the bottom wall an extended or enlarged work surface. The support structure may support the cabinet at such a height that the bottom wall thereof will be located on desktop level, and may comprise four stationary legs, one at each of the four corners of the rectangular bottom wall of the cabinet. Alternatively, the support structure may comprise side panels forming part of a secondary storage compartment located below the cabinet and having at least one closable door arranged to open and close below the displaceable panel when the latter is in the open position. The secondary compartment may be utilised for storing equipment or accessories, and may optionally be provided with one or more shelves. Two laterally spaced foldable support legs may conveniently be provided to support the displaceable panel when it is in the open position, the legs being positioned to support the said panel at unsupported edge regions thereof, eg at or near each of the two unsecured corners of the said panel. As indicated above, a foldable support leg may be comprised of two elongated sections hingedly secured together in coaxially aligned relative positions. The free end of the or each support leg connected hingedly to the displaceable panel may be connected at or near an unsecured corner of the displaceable panel. The other free end of the or a support leg connected pivotally to the support structure may be connected, such as by means of a transverse pin, to the stationary legs of the cabinet where such legs are provided, or to the side panels forming part of a secondary compartment. The said pivotal connection of the foldable legs may preferably be to points at or near the lowermost or basal part of the article, ie to be located at or near the floor when the article is used. In use, when the displaceable panel is brought to its open position, i.e a position in which it is disposed substantially horizontal and coplanar with the bottom wall of the cabinet, its forward unsupported corners will be supported by the foldable support legs, which support legs will have been supported on their hinge points. One section of either support leg, i.e. the section hingedly secured to an unsupported corner of the displaceable wall, will be the one extending downwardly substantially upright to serve as a leg, while the other section of a support leg, i.e. the section pivotally secured to the basal or lowermost part of the article, will extend between the article and the hinge point. In practice this will usually be along the ground, thus providing a stable and sturdy support structure. The article according to the invention may be made of wood, to serve as a useful piece of furniture. For example, the unit may be used as a fold-away desk, in which case the cabinet may have one or more shelves or drawers for books and other items. The unit may also be used as a fold-open book case for containing books, so that the folded-out front wall nay provide a working area where a book may be read or otherwise used. In a preferred embodiment, the unit may be used as a cabinet for a sewing machine, a food processor or the like. Thus, the cabinet may be used to house a sewing machine, and if desired also an overlocking machine, provided on the displaceable platform. The platform may, for example, be rotatably secured to the bottom wall by a single rotational pin or peg, so as to be capable of being pivoted or swivelled around the pin or peg from an inoperative position on the bottom wall within the cabinet, to an operative position on the extended work surface. Alternatively, the platform may be slidably displaceable, and a slide track may be provided to control the displacement of the platform, the track having stop means to permit limited linear sliding displacement of the displaceable platform along the track from the inoperative retracted position to the operative extended position. In this manner the appliance may be brought into a more accessible position, where it is within easy reach for an operator to work on. When the appliance is not being used, it may be moved away on its platform to the inoperative position, the cabinet may be closed, and the work area will look tidy. The unit may also be used as a work station for a personal computer, word processor, typewriter or the like. If desired, the computer, word processor or typewriter may again be placed on the displaceable platform to be displaced from an inoperative position at the back of the cabinet, to an operative position in front on the extended wall. Where the appliance is a computer or a word processor having a separate keyboard, the keyboard may be mounted on the displaceable panel, conveniently on the upper surface thereof. When the panel is then moved to the closed position, the keyboard will be put away inside the cabinet, where it may for example hang suspended against the inside of the said panel. The unit according to the invention may be of any suitable dimensions, as required in use. If desired, it may be of such lateral dimensions that more than one appliance may be positioned therein, one adjacent the other. The invention and the manner in which it may be put into practice will now be described by way of example, with reference to the accompanying diagrammatic drawings. In the drawings Figure 1 is a diagrammatic three-dimensional view of an article of furniture in accordance with the invention, in the form of a cabinet for an appliance such as a sewing machine, shown in the open position; Figure 2 is a diagrammatic three-dimensional view of the cabinet of Figure 1, but shown in the closed position; and Figure 3 is a diagrammatic three-dimensional view of a different embodiment of a cabinet intended for a sewing machine, and shown in the open position. Referring to the drawings, there is provided in accordance with the invention an article of furniture in the form of a cabinet for an appliance such as a sewing machine, computer work station, etc which comprises a closed rectangular cabinet generally shown as 10, having a bottom wall 12, a top wall 14, a displaceable front wall or panel 16, a rear wall 18, and side walls 20, 22. The cabinet 10 shown in Figures 1 and 2 is supported on four stationary legs 24, 26, 28, 30 provided at the four corners of the bottom wall 12, the legs being of such a height and configuration that the bottom wall 12 of the cabinet is located on desktop level. A transverse strut 32 is provided between the two rear legs 26, 30. In the embodiment shown in Figure 3, the cabinet 10 is supported on the side panels 70, 72 the upper parts of which form the side walls 20, 22 of the cabinet 10. The lower parts of the side panels 70, 72 form part of a secondary compartment generally indicated as 74, as explained more fully further below. The front wall 16 of the cabinet is mounted on the bottom wall 12 by means of hinges 34, 35 and 36 as shown in Figures 1 and 3, to enable it to be displaced from an upright closed position, as shown in Figure 2, in which it closes the cabinet 10 and obscures its contents from view, and an open position as depicted in Figures 1 and 3, in which it is disposed substantially horizontally and level with the bottom wall 12 of the cabinet 10. It will be evident that the bottom wall 12 of the cabinet constitutes a support surface 12.1 on which appliances or other items may be supported. When the displaceable wall 16 is brought to its open position, it provides a work surface 16.1 level with the support surface, and together the two surfaces constitute an enlarged working area. Two foldable support legs generally shown as 38 and 40 are provided to support the displaceable wall 16 in its open position. Each support leg comprises two elongated sections 38.1, 38.2 and 40.1, 40.2 respectively, the two sections of a leg being secured together by means of hinges 42, 44. One free end of each support leg 38, 40 is secured near the free corners of the displaceable wall 16 by means of hinges as shown at 46, 48. The other free end of each support leg 38, 40 is pivotally connected to a stationary part of the article, preferably at a point close to the ground. Thus, in the embodiment shown in Figures 1 and 2, the foldable legs 38, 40 are secured to the front stationary legs 24, 28 of the cabinet 10, by means of transverse pins 50, 52. As shown in the drawings, these ends of the foldable legs 38, 40 so connected are rounded, as shown at 54, 56, to enable the foldable legs 38, 40 to pivot relative to the stationary legs 24, 28. In the embodiment shown in Figure 3, the foldable legs 38, 40 are pivotally connected to the side panels 70, 72 by means of pins 76, 78. The end configuration of the legs is again rounded, as shown at 80, to permit pivotal movement. In use, when the displaceable wall 16 is brought to its open position, as depicted in Figures 1 and 3, the foldable legs 38, 40 are extended into supports of angular configuration, with sections 38.2 and 40.2 extending along the floor between the stationary supports 24, 28 and 70, 72 and the hinge points 42, 44, and sections 38.1 and 40.1 being positioned substantially upright to support the wall 16 in the open position. The hinge points 42, 44 rest on the ground. When the displaceable wall 16 is brought to the closed position, as depicted in Figure 2, in which it is disposed upright to form the front wall of and to close the cabinet 10, both foldable support legs 38, 40 are drawn up and straightened until they are positioned adjacent the front face of the cabinet 10. If necessary, suitable clip-in securing devices (not shown) may be provided in suitable positions on the foldable legs 38, 40 and the displaceable wall 16, to secure the legs 38, 40 against the wall 16 when the latter is in the closed position. In the embodiment shown in Figure 3, a secondary closable storage compartment 74 is provided below the cabinet 10. This compartment will serve to support the cabinet 10, and will provide additional storage space. The compartment 74 is provided with closable doors 82, 84 which open below the displaceable panel 16, and may have one or more shelves 86, as may be required in practice. The unit according to the invention may be made of wood, to serve as a versatile and useful piece of furniture. For example, the unit may be used as a fold-away desk, in which case the cabinet 10 may have one or more shelves or drawers for books and other items. The unit may also be used as a fold-open book case for containing books, so that the folded-out front wall may provide a working area where a book may be read or otherwise used. In a preferred embodiment, as illustrated in Figures 1, 2 and 3, the unit may be used as a cabinet for a sewing machine, food processor or the like. Thus, the cabinet 10 may be used to house a sewing machine (not shown). In this case, one or more special displaceable platforms 58, 59, 61 are provided on which the appliance, eg the sewing machine and/or overlocking machine (not shown), may be placed. The platforms 58, 59, 61 are placed on the bottom wall 12 of the cabinet, and are displaceable from an inoperative retracted position on the bottom wall 12 of the cabinet 10 (as shown in broken lines in Figure 2), to an operative extended position on the extended work surface 16.1 of the displaceable wall 16 (as shown in Figures 1 and 3). For example, the displaceable platform 58 shown in Figures 1 and 2 may be rotatably secured by a single upright pin or peg 60, so as to be capable of being pivoted or swivelled around the pin or peg 60 from an inoperative retracted position on the bottom wall within the cabinet (as shown in broken lines in Figure 2), to an operative extended position on the extended front wall 16, as shown in Figure 1. Alternatively, the displaceable platforms 59, 61 shown in Figure 3 may be rectilinearly slidable by way of slide tracks in the form of grooves shown in broken lines in Figure 1, and stop buttons 90, to permit linear sliding displacement of the platforms from the retracted inoperative position within the cabinet 10, to the extended operative position as depicted in Figure 3. In this manner the appliance placed on a platform may be brought into a more accessible position, where it is within easy reach for an operator to work on. When the appliance is not being used, it may be displaced on its platform to the retracted inoperative position, the cabinet 10 may be closed, and the work area will look tidy. It should be understood that further utility features may be added to the article, to improve its versatility and utility. Thus, as illustrated in Figure 3, pegs 94 may be mounted against the rear wall 18 of the cabinet 10 to hold reels of cotton (not shown) where the cabinet is to be used for housing a sewing machine. An additional drawer 96 may also be provided. The unit may also be used as a work station for a personal computer, word processor, typewriter or the like. If desired, the computer, word processor or typewriter may again be placed on the platform 58, 59 or 61 to be displaced from an inoperative retracted position at the back of the cabinet, to an operative extended position in front on the extended wall 16. Where the appliance is a computer or a word processor having a separate keyboard, the keyboard may be mounted on a specially provided shelf (not shown), or it may be mounted on the surface 16.1 of the displaceable wall 16. When the wall 16 is then moved to the closed position, the appliances will be put away inside the cabinet 10, where they will be stored in a safe and tidy manner.
