1 CLOTHES RACK FIELD [0001] The invention concerns a clothes rack, particularly a collapsible clothes rack. BACKGROUND [0002] Clothes racks provide upright structures from which wet clothing can be hung to dry. Although a variety of clothes racks have over the years been developed a large number of those clothes racks tend to be bulky and heavy. This renders them awkward to operate, particularly for elderly or infirm operators. [0003] The construction of numerous known clothes racks is such that they are not suitable for use within the confined spaces of apartment balconies. The by-laws of most strata title developments further determine that laundry may not be dried on balconies where such drying laundry will be visible from outside the strata development. Such by-laws effectively prohibit the use of many known clothes racks. OBJECT [0004] It is the object of the present invention to substantially overcome or at least ameliorate one or more of the above disadvantages, or to provide a useful alternative. SUMMARY [0005] According to a first aspect of the present invention there is disclosed herein a clothes rack comprising: a clothes frame operatively adapted for movement between an upright orientation and a collapsed orientation; one or more frame bracket(s) to attach the clothes frame to a support surface; one or more support arm(s) to support the clothes frame in the upright orientation; and one or more arm bracket(s) to secure the support arm(s) to the support surface when the clothes frame is located in the upright orientation, (88938161):AEM 2 wherein the frame bracket(s) is adapted (i) to be clipped onto the clothes frame to attach the clothes frame to the support surface and (ii) to be unclipped from the clothes frame to remove the clothes frame from the support surface. [0006] Preferably the frame bracket(s) comprises a C-shaped clip formation. [0007] Preferably the support arm(s) is pivotally attached to the clothes frame. [0008] Preferably the support arm(s) includes a C-shaped clip operatively associated with a transverse shaft of the arm bracket(s) and adapted to clip onto the shaft when the clothes frame is located in the upright orientation. [0009] Preferably the support arm(s) comprises an elongate member and a C-shaped frame connector, wherein the frame connector is adapted for attachment to the clothes frame and the elongate member is pivotally attached to the frame connector. BRIEF DESCRIPTION OF THE DRAWINGS [0010] A preferred embodiment of the present invention will be described hereinafter, by way of an example only, with reference to the accompany drawings, wherein: [0011] Figure l is a perspective view of an embodiment clothes rack located in an upright orientation; [0012] Figure 2 is a perspective view of the clothes rack of Figure 1 in a collapsed orientation; [0013] Figure 3 is a perspective view of a portion of the clothes rack of Figure 1 showing a frame bracket; and [0014] Figure 4 is a perspective view of a portion of the clothes rack of Figure 1 showing a support arm detached from its corresponding arm bracket. (88938161):AEM 3 DESCRIPTION OF EMBODIMENT [0015] Figure 1 shows an embodiment clothes rack, generally indicated with the reference numeral 10. The clothes rack 10 comprises a clothes frame 12 operatively adapted for movement between an upright orientation, shown in Figure 1, and a collapsed orientation shown in Figure 2. The clothes frame 12 comprises a plurality of individual aluminium sections 14 that are attached to form a rectangular shape. The aluminium sections 14 of the clothes frame 12 have been anodised and powder coated for protection. [0016] A clothes line 16 is suspended between elongate sections 14 of the clothes frame 12. The clothes line 16 comprises a plastic coated metal wire. The wire has been plastic coated to deter rusting. The plastic coating further serves to strengthen the clothes line 16. [0017] The clothes rack 10 comprises two frame brackets 18 for attaching the clothes frame 12 to a support surface, typically an upright wall. Referring also to Figure 3, each frame bracket 18 comprises a base 20 having two bosses 22 which define passages 24. In use fasteners, such as screws, pass through the passages 24 to secure the base 20 to the support surface. [0018] The frame brackets 18 include a C-shaped clip formation 26. The C-shaped clip formation 26 is adapted to be clipped onto a section 14 of the clothes frame 12 when the clothes frame 12 is required to be secured to the support surface holding the frame brackets 18. To remove the clothes frame 12 form the support surface, the frame brackets 18 are adapted to be unclipped from the clothes frame 12. [0019] To secure the clothes frame 12 in the upright orientation of Figure 1, the clothes rack comprises two support arms 28. The support arms 28 each comprise an elongate member 30 having a C-shaped clip 32 at one end and a C-shaped frame connector 34 at the other end. The frame connector 34 is pivotally attached to the elongate member 30 atjoint 36. The frame connectors 34 in turn are attached to sections 14 of the clothes frame 12. [0020] The clothes rack 10 further comprises two arm brackets 38. Referring to Figure 4, each arm bracket 38 comprises a base 40 with two outwardly extending flanges 42. A transverse shaft 44 extends between the flanges 42. The C-shaped clip 32 of the support arm 28 is adapted to clip onto the shaft 44 of the arm bracket 38 when it is required to secure the clothes frame 12 (88938161):AEM 4 in the upright orientation of Figure 1. When it is required to locate the clothes frame 12 in the collapsed orientation of Figure 2, the C-shaped clip 32 is unclipped from the shaft 44. The clothes frame 12 is thereafter allowed to pivot within the frame brackets 18 so as to move under the influence of gravity to the collapsed orientation. [0021] In one particular application the clothes rack 10 can be secured to a balcony parapet. For this application the clothes frame 12 is sized so that when the clothes frame is in the upright orientation it will not protrude beyond the upper edge of the balcony parapet. The clothes frame 12 is further sized such that in the collapsed orientation the clothes frame 12 and support arms 28 will hang flush with the parapet. Those features of the clothes rack 10 provide that laundry can be dried on an apartment building but be hidden from sight. Further, when not in use the clothes rack 10 will occupy a minimal area so as not to waste space on the balcony when not in use. As the clothes rack is produced from light material, in this embodiment aluminium, it is light and its relative low installation position facilitates ease of use, particularly for elderly or infirm operators. Also, if it is desired to remove the clothes rack 10 from the parapet, for example to store indoors, the clothes frame 12 can simply be unclipped from the frame brackets 18. [0022] The clothes rack 10 can be employed during camping and caravan trips. The fact that the clothes rack 10 can be easily removed makes it possible to be removed from its domestic fitment and taken along on, for example, camping trips. [0023] The frame brackets and arm bracket are produced from a UV stable plastic material to avoid rust issues. [0024] The aluminium clothes frame can be anodised in different colours so as to blend in with different building constructions. [0025] In a non-illustrated embodiment the clothes frame is size-adjustable, for example, by providing that some of the aluminium section are telescopically coupled. [0026] In a further non-illustrated embodiment the clothes rack supports a table. Such arrangement may be particularly beneficial to optimise the limited space of an apartment balcony.
