    - 1 SUPPORT ASSEMBLY This invention relates to a support assembly and in particular relates to a bracket and arm assembly for use 5 with a fold down clothes line. A clothes line is a necessary yet unsightly feature of any garden. In order that the clothes line does not cause an unsightly obstruction in a garden, there are a 10 number of clothes line assemblies that can be placed in an inoperative configuration when not in use. One such assembly is a retractable clothes line in which the line is wound on a spool mounted in a housing. The line can be wound back onto the spool into the housing when in the 15 stored configuration. Another form of clothes line comprises a folding frame that in use extends perpendicularly to its support but is arranged to pivot downwardly to a folded configuration for storage. A problem with this type of foldable line assembly is the 20 mechanism that controls the installation in either the operative or inoperative positions. The mechanism is complicated and exposed thereby introducing entrapment risks. A further problem that can be encountered with this type of assembly occurs where the frame is supported 25 in its operative position by bracing members that extend beneath the frame. Clothes line frames are usually mounted above head height but the bracing members are considered to be a potentially dangerous obstruction. 30 There is also a need for a fold-down clothes line to be operable single handed. It is these issues that have brought about the present invention. 35 According to one aspect of the invention there is provided a bracket and arm assembly having one end of an 4101327_1 (GHMatters) P87635.AU.1 21/02/13 - 2 arm pivotally secured to a bracket to pivot from a folded configuration to an operative position in which the bracket supports the arm in a cantilever fashion, the bracket having an enclosure adapted to accommodate the end 5 of the arm, the enclosure having a pair of spaced slots to accommodate a pin that extends across the slots and through the arm to locate the arm in the bracket, the enclosure being profiled so that when the pin is at one end of the slots the arm can pivot to the folded 10 configuration and when the pin is at the other end of the slots the enclosure impedes pivotal movement of the arm thus supporting the arm in the cantilever fashion. The enclosure preferably comprises two parallel wall 15 portions with each wall portion defining a slot. Preferably the other end of each slot has an upturned portion whereby when the pin is located in the upturned portion the sliding motion of the pin within the slots is 20 impeded. The enclosure preferably comprises a mouth that merges into a closed end, the first end of the slots being positioned adjacent the mouth of the enclosure with the 25 other end being adjacent the closed end, the mouth of the enclosure defining sufficient space to allow the arm to pivot between the folded and operative configurations whilst the closed end of the enclosure defines an abutment that prevents movement of the arm and supports the arm in 30 the cantilever fashion. Preferably the bracket is moulded in plastics and includes flanges on either side of the enclosure facilitating mounting of the bracket to a post or wall 35 structure. Embodiments of the present invention will now be described by way of example only with reference to the 4101327_1 (GHMatters) P87635.AU.1 21/02/13 - 3 accompanying drawings in which: Figure 1 is an exploded perspective view of components of a bracket and arm assembly in accordance 5 with the first embodiment, Figure 2 is an end elevational view of the bracket and arm assembly, Figure 3 is a cross sectional view in plan of the assembly, 10 Figure 4 is a sectional side elevational view of the assembly showing an arm in an inoperative position, Figure 5 is a sectional side elevational view of the bracket showing the arm in the operative position, Figure 6 is an exploded perspective view of 15 components of a bracket and arm assembly in accordance with a second embodiment, Figure 7 is an end elevational view of the bracket and arm assembly shown in Figure 6, Figure 8 is a cross sectional view in plan of the 20 assembly, Figure 9 is a cross sectional side elevational view showing an arm in an inoperative position, Figure 10 is a cross sectional side view showing the arm in an operative position, 25 Figure 11 is a front perspective view of a typical twin framed clothes line with one frame up (operative) and the other down (inoperative), and Figure 12 is a front perspective view of the clothes line with both frames up. 30 In a first embodiment shown in Figures 1 to 5 a bracket and arm assembly 10 comprises an injection moulded plastics bracket 11 that supports an arm 12 that is formed of metal tubing of rectangular cross section. A hole 13 35 is drilled across the tubing a short distance from the inner end 14 of the tubing. 4101327_1 (GHMatters) P87635.AU.1 21/02/13 - 4 The bracket 11 has mounting flanges 15 and 16 that extend outwardly from a central body 17. Each mounting flange includes a recessed hole 18 into which a suitable fastener can be located to secure the bracket 11 to a post 5 or wall surface (not shown). The bracket body 17 has two parallel wall portions 21, 22 that define an enclosure with an open mouth 23 and closed inner end 24. Each wall portion 21, 22 is furnished with elongate slot 30. A guide pin 31 with an enlarged head 32 at one end is 10 arranged to extend across the slots 30 to be a sliding fit within the slots. The guide pin 31 also extends through the hole 13 in the arm 12 and a circlip 35 locates the guide pin 31 in position across the slots 30 while supporting the end of the arm 12. A pair of side caps 36, 15 37 clip into recesses 38 on either end of the slots to close off the assembly. In a foldable clothes line two bracket and arm assemblies 10 are positioned spaced apart each defining a 20 frame of elongate rectangular construction with clothes lines extending from side to the other (see Figures 11 and 12). The arms pivot relative to the bracket so that in an inoperative position the arm is folded down to hang in a substantially vertical array as shown in Figure 4. In the 25 operative position the arm extends horizontally and operates as a clothes line that extends outwardly from the bracket 11 in a cantilever fashion. As shown in Figures 2 to 5 the enclosure defined by 30 the wall portions 21, 22 defines two parallel sides defined by the wall portions 21, 22, an open mouth 23 and a closed end 24. The roof 25 of the enclosure tapers downwardly, as shown in Figure 4 from the mouth 23 and the base 26 of the enclosure stops short of the mouth 23. 35 When the arm 12 is pivoted to the inoperative position shown in Figure 4 it rests against the lower face of the body 17 in a substantially vertical configuration. The 4101327_1 (GHMatters) P87635.AU.1 21/02/13 - 5 guide pin 31 is at the forward end of the slots 30 in each wall portion 21, 22. To lift the arm 12 to the operative position it is 5 pulled upwardly whilst the pin 31 is in the forward end of the slots 30. There is sufficient room between the end 14 of the arm 12 and the roof 25 of the enclosure to allow the pivoting motion until the arm 12 is horizontal, at which stage the pin 31 can be slid along the slot 30 to 10 the inner end. In that situation, the top and bottom of the arm 12 are in close abutting contact with the roof 25 and base 26 of the enclosure which means that the arm cannot pivot relative to the bracket see full line view in Figure 5. 15 Although not shown in the drawings the inner end of the roof 25 has a downwardly projecting small circular boss which is a close fit with a small hole in the inner end of the arm to locate the arm in the support position 20 shown in Figure 5. The bracket thus supports the arm in a cantilever fashion so that two arms and a frame constitute a clothes line to support garments and the like. The cantilever 25 support is between the arms and the brackets and not through the pins 31 that merely act as a guide. As shown in Figures 4 and 5 the inner end of the slot has a slightly upturned end portion 41 having a downturned 30 edge defining a notch 42. When the clothes line is in the operative position the pin 31 is located in the upturned wall portion 41 and the notch 42 prevents a forward sliding motion of the pin 31. Thus, to release the clothes line from the operative to the inoperative 35 position the arms 12 have to be pulled upwardly past the horizontal thereby causing the pin 31 to ride up the notch 42 on the upturned end portion 41. This upward pull on 4101327_1 (GHMatters) P87635.AU.1 21/02/13 - 6 the arm also releases the boss in the bracket roof from the hole in the arm. In this position the arm 12 can be pulled forward so that the pin 31 moves to the forward end of the slot 30 allowing the arm to pivot down to the 5 inoperative configuration shown in Figure 4. In the embodiment shown in Figures 6 to 10, a twin bracket assembly 100 is shown where the enclosure has a central web 101 and two parallel wall portions 102, 103 10 and slots 31 are provided in both the wall portions 102, 103 and the central web 101. The bracket 111 has two enclosures, thus allowing the bracket to support two arms 112, 113. 15 As shown in Figure 11, the outer arms 112 form part of a larger rectangular clothes line frame 120 and the inner arms 113 support a shorter rectangular clothes line frame 121. With both the frames 120, 121 erect as shown in Figure 12 the larger 120 frame extends out past the 20 shorter inner frame 121. Figures 11 and 12 illustrate typical foldable clothes lines without use of the support assemblies discussed above. As shown in Figures 7 and 8 the means of mounting the 25 arms to the support brackets is the same as in the first embodiment with the use of circlips on the ends of the pins. The axis can pivot between the operative and inoperative positions in the same manner as the first embodiment. 30 The support assemblies provide cantilever support for the frames without the need for obstructive braces. The clothes line can also be raised or lowered in a single handed operation. The assembly described above has been 35 specifically designed to reduce the likelihood of entrapment. The bracket shields the cantilever support of the arms. The surfaces that interact are housed within 4101327_1 (GHMatters) P87635.AU.1 21/02/13 the bracket and thus not exposed. In the claims which follow and in the preceding description of the invention, except where the context 5 requires otherwise due to express language or necessary implication, the word "comprise" or variations such as "comprises" or "comprising" is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further 10 features in various embodiments of the invention. 4101327_1 (GHMatters) P87635.AU.1 21/02/13
