    KNOCK-DOWN BUNK BEDBACKGROUND TO THE INVENTIONTHIS invention relates to a knock-down bunk bed, and moreparticularly, but not exclusively, to a knock-down bunk bedthat is assembled using releasable clips.
    A bunk bed is a type of bed in which one bed frame islocated on top of another. The nature of bunk beds allowstwo or more people to sleep in the same room whilemaximizing available floor space. This leads to bunk bedsbeing used in places with limited floor space, such as onships, in army garrisons or in places where floor spaceneeds to be maximized, such as for example refugee camps.Bunk beds are normally supported by four poles or pillars,one at each corner of the bed. A ladder may be used toaccess the upper bed, which is normally surrounded by arailing to prevent the sleeper from falling out. Bunk bedscan be made from wood or steel, and are often sold anddelivered in a fully assembled condition.
    Ready-to-assemble furniture, also known as knock-downfurniture or flat pack furniture is a form of furniturethat requires customer assembly. The furniture componentsare typically packaged iJ1 a carton which also containsassembly instructions and necessary hardware needed for thefollow furniture itembuyer to in order to build thecorrectly. Ready-to-assemble furniture is typicallypackaged in a kit form with the pieces packaged in one ormultiple boxes. The kit may contain a number of flat parts,fasteners, and other parts that are needed to assemble thefurniture.15-Ready-to-assemble furniture is popular among consumers whowish to save money on their furniture purchases byassembling the product on their own and also by saving ondelivery cost. In addition to saving the consumer money,flat pack furniture is generally simple to assemble andrequires only the use of simple tools. Since the furnituredoes not need to be assembled in the factory, ready-to-assemble furniture is often also less expensive.
    Bunk beds are available in the marketplace in a ready-to-assemble configuration, but a few disadvantages areassociated with existing designs, especially where rapidmanufacturing, deployment and assembly is concerned. Forexample:the material used are typically selected with residentialuse in mind, and are not sufficiently robust for deploymentin a more rugged environment, for example militaryapplications and refugee camps;the bunk beds still require a significant degree of manuallabour to erect, and for example requires the use of screws,and thus the concomitant tools, screw drivers;e.g.the pillars of the bunk beds have to carry a significantload, and are therefore usually designed to have arelatively large cross-sectional surface area, which inturns renders the collapsed bunk bed relatively bulky,which is of particular concern where bunk beds have to bedistributed in large quantities;Existing ready-to-assemble bunk beds are not designed withthe view of rapid disassembly and redeployment in mind,which is a drawback in application where large scaleassembly, disassembly and redeployment is required;the mechanisms and the materials utilized_ in existingready-to-assemble bunk beds have been designed. with asingle assembly in mind, and although capable of beingdisassembled and redeployed, the securing mechanisms caneasily damage, for example because it relies on threadedfasteners that can easily be impaired. Also, the panelsused are often made from chipboard, which is structurallyweak, and which cannot used in applications where fasteningclips are used because the grooves / slots machined inchipboard. will not last long, and. will quickly' becomeunusable.
    It is accordingly an object of the invention to provide aknock-down bunk bed that will, at least partially,alleviate the above disadvantages.It is also an object of the invention to provide knock downbunk bed which will be a useful alternative to existingbunk beds.
    SUMARY OF THE INVENTIONAccording to the invention there is provided a knock-downbunk bed including:a plurality of flat panels, the panels includingcomplementary engagement formations; andfastening clips for selectively securing the panelsrelative to one another.

Further, "connected" and "coupled" are notrestricted to physical or mechanical connections orcouplings. It is noted that, as used in this specificationand the appended claims, the singular forms "a," "an," and"the," and any singular use of any word, include pluralreferents unless expressly and unequivocally limited to onethe term. “include” and. itsreferent. As used. herein,grammatical variants are intended to be non-limiting, suchthat recitation of items in a list is not to the exclusionof other like items that can be substituted or added to thelisted items.
    Referring to the drawings, in which like numerals indicatelike features, a non-limiting example of a knock down bunkbed in accordance with the invention is generally indicatedThe knock down bunk bed l0(20, 30)by reference numeral 10.includes a plurality of panels that are releasablysecurable to one another in order to form a collapsibleframe for a bunk bed, which can then in turn receive asleeping panel 40, alternatively a sleeping sheet 60. Thepanels are all substantially flat and planar, and also allof similar thickness.
    Two end panels 20 are provided, and in use oppose oneanother when the bunk bed l0 has been assembled. Each endpanel 20 is in the form of substantially flat sheet ofmaterial, and is preferably in the form of a wooden panel.
    Each end panel 20 has a lower edge, which in use abuts thesurface on which the bunk bed l0 is located, and an upperedge 22 at an opposite end of the panel 20. Moreparticularly, foot formations 21.1 extend from the loweredge, which in use abuts the surface on which the bunk bed10 is located. Each end panel 20 also has two oppositeside edges 23 that are in use orientated in a verticalorientation.
    The side panels 30 are secured to the side edges 23 of theend. panels 20 when the bunk bed. is erectedd In oneembodiment rebates 23.1, which define tongue formations23.2 therebetween, are provided in the side edges 23 of theend panels 20. The rebates 23.1 and corresponding tongueformations 23.2 are configured and dimensioned for engagingcomplementary receiving apertures 35 provided in end zones31 of the side panels 30. Downwardly' directed. forcesexerted on the side panels 30 are therefore transmitted tothe end panels 20, with the end panels 20 serving as theprimary structural supports. Apertures 25 are furthermoreprovided in the end.panels 20, and in use serves as landingsfor end lip formations 45 that extend from the sleepingpanels 40. The apertures 25 also serve as footholds forallowing' a used. to climb on to the top level of theassembled bunk bed.
    Each side panel 30 is also in the form of a substantiallyflat sheet of material, and is preferably in the form of awooden panel. Two side panels 30 are provided for eachsleeping surface required, and in this particularembodiment four spaced apart side panels 30 are provided,thus defining two vertically spaced apart sleeping areas.
    The side panels 30 are of elongate configuration andterminate in two oppositely directed end zones 31. Areceiving formation 35 is provided in each end zone 31 fordescribed. above. Eachthe purposes as side panel 30furthermore includes an operatively upper side 33 and anlloperatively lower side 32. A recessed zone 34 is providedin the operatively upper side 33, and serves as a landingfor receiving a side lip formation 44 that extends from aside of a sleeping panel 40. In addition, further receivingslots 37 are provides towards the end zones of the sidepanels, and in use receives corner lip formations 47extending from corner zones of the sleeping panel 40. Inthe embodiment shown. in Figure 3, the side panel alsoincludes a shoulder formation 38 that in use abuts againstthe end panel 20, and which improves the overall stabilityand rigidity of the bunk bed l0.
    In the embodiment of Figures l to 5, the sleeping surfaceis defined by a sleeping panel 40 on top of which a mattressor other bedding can in use be located. The sleeping panel40 is in the form of a flat sheet of material, having twoopposite ends 42 and two opposite sides 43. Side lipformations 44 extend from the sides 43 of the panel 40, andend lip formations 45 extend from the ends 42 of the panels.Corner lip formations 47 in addition extend from sides ofthe sleeping panels, towards the corners of the sleepingpanels.
    In a second. embodiment, shown in Figure 6, a pliablesleeping sheet 60 may be used instead of a rigid sleepingpanel 40. In this embodiment, the bunk bed l0 willessentially be in the form of a frame for holding hammock-like sleeping arrangements. A benefit of this design isthat no mattress will be required. This embodiment willstill include a sleeping panel 40, but in this case theinner, proximal area of the sleeping panel 40 will have anopening provided therethrough, thus only leaving astructural, annular rim that will provide rigidity to thel2frame. The pliable sleeping sheet 60 will be located insidethe opening in the proximal zone of the sleeping panel 40.
    It will be appreciated that a force exerted on the sleepingpanel 40 or the sleeping sheet 60 will be transferred ontothe end panels 20 and the side panels 30. The resultantforces exerted. on the side panels 30 will in turn. betransferred to the end panels 20, with the end panels thusforming the primary load bearing support structure.
    However, instead of using discrete pillars, as is the casewith prior art bunk beds, wide end panels 20 are used,which reduces the packed volume of the knock-down bunk bedbecause the panels can be thinner as a result of them beingwider than conventional pillars, thus retaining asufficient area and strength required to absorb therelevant loads.
    The entire assembly is kept together by way of fasteningclips 50. In one embodiment (shown in the figures) thefastening clips 50 are in the form of resilient steel clips,having end sections adapted to engage engagement slots (25,36 and 46) formed in the end panels 20, side panels 30 andsleeping panels 40 respectively. The clips 50 are commonlyused in the field of collapsible crates, and have a proventrack record insofar as strength, durability and ease ofoperation are concerned.the fastening clips mayIn another embodiment (not shown)be in the form of plastic clips, in which there is providedfor each fastening clip to include two legs extending awayfrom one another, the legs being connected at one end, witheach leg having an opposite free end that terminates in apanel engagement formation; characterized in that at leastone of the panel engagement formations is an adjustablel3engagement formation that is adjustable between a lockedposition, in which the engagement formation is adapted toengage a securing' aperture provided. in a jpanel, and. arelease position, in which. the engagement formation isadapted to be released from the securing aperture. In thisembodiment, the engagement formations are in the form ofapertures extending through the respective panels, with thefastening clips, and more particularly the engagementformation of the fastening clips, engaging the panels viathe apertures.
    The fastening clips 50 pull the various panels (20, 30 and40) together and hold them in place, but do not have toabsorb the downward forces exerted on the panels by a userof the bunk bed. Instead, those forces are taken up by theend panels 20 via the receiving apertures 35 of the sidepanels 30 and the lip formations (44, 45 and 47) of thesleeping panels 40.
    Advantageously, the configuration is such that the entireknow-down bunk bed assembly can be packed in a very smallvolume when not in use. This is because of the use of thinpanels, instead of more bulky pillars and supports as foundin the prior art. The panels typically have a thicknessof about l0 to 20mm, resulting in a small packed volume.
    The panels can furthermore be secured to one another in thepacked position using the same fastening clips used toassemble the bunk beds, thus rendering the packed unitsimple, robust and space efficient. The panels arefurthermore made from a hard wooden material, for exampleplywood, which is structurally strong and robust, and whichis also sufficiently hard for allowing engagement slots tobe machined into the panels.14It will be appreciated that the above is only one embodimentof the invention and that there may be many variationswithout departing from the spirit and/or the scope of theinvention.
