IMPROVED SHELVING

Abstract: A shelving structure for use on a balcony wall or railing comprises a base (2) for providing a substantially horizontal supporting surface, one side edge of the base being securable to the wall or railing by means of brackets (7). Slide members (101, 102) are slidably mounted to side members of the base for movement towards and away from said one side edge and can be secured against sliding movement at preselected locations on the base. First and second levers (9, 8) pivotally depend below the base from respective locations on the slide members with the second lever (8) being pivoted to the slide member at a location intermediate the first lever and said one side edge of the base. The first lever (9) carries a number of lugs (912, 922) which engage with the free end of the second lever (8) while the free end of the first lever bears against the balcony wall or railing and is retained there by engagement of the second lever to support the base in a substantially horizontal attitude against the balcony wall or railing.

Description: This invention relates to supporting structures for use as shelving for balcony walls or railings. People residing in apartments in general have a tendency to install shelving or the like on their balconies for supporting flower arrangements or other articles to provide decorative living surroundings. However, where such shelves are permanently installed it proves difficult and sometimes impossible for the residents to remove them without damage when the residents move to different premises. In such cases the shelves have to be left behind. Attempts have been made to solve the above problems and one known form of shelving comprises a shelf supported by a U-shaped frame which is locked in position by catches and is removably attached to the balcony enclosure or railing as is shown in Figure 10. However, this type of shelving is bulky and cumbersome for both packing and handling and is relatively expensive. Another form of shelving for a balcony is shown in CH-A-339349 upon which the pre-characterising portion of claim 1 is based. Here, a fold-down shelf is supported at each side by the arms of a U-shaped hoop, with a hook and lever mechanism being provided for the support and adjustment of the shelf. In accordance with the present invention there is provided a supporting structure for use as shelving on a balcony wall or railing, comprising base means for providing a substantially horizontal supporting surface, one side edge of said base means being securable to said wall or railing; first and second lever means pivotally depending below said base means, said second lever means being pivoted at a location intermediate said first lever means and said one side edge; and engaging means on said first lever means for retentive engagement with said second lever means whereby said first lever means serves as a lever for supporting said base means in a substantially horizontal attitude against the balcony wall or railing, characterised by slide means, slidably mounted to said base means for movement towards and away from said one side edge, said slide means having means for securing the slide means against sliding movement at preselected locations on said base means; and in that said first and second lever means are pivotally connected to said slide means, with said engaging means being enjoyable with said second lever means remote from the slide means. Preferably, each of the first and second lever means comprises a generally U-shaped member pivotally connected at or adjacent to the free ends of the legs thereof to said slide means. In a preferred embodiment, the engaging means on the first lever means comprises a plurality of equally spaced projecting lugs on which said second lever means is arranged to rest. Further preferred embodiments of the invention are defined in claims 4 to 7. The present invention is further described hereinafter, by way of example, with reference to the accompanying drawings, in which: Figure 1 is an exploded view of a support structure according to the present invention; Figure 2 is a plan view from below of a frame of the structure of Figure 1; Figure 3 is a perspective view of a modified form of supporting bracket for the structure of Figure 1; Figure 4 is a perspective view of a further form of supporting bracket for the structure of Figure 1; Figure 5 is a perspective view of the structure of Figure 1 in assembled form; Figure 6 is a side elevation of the structure of Figure 1 mounted in a first manner on a supporting wall; Figure 7 is a view similar to that of Figure 6 showing the structure mounted in a second manner on supporting wall; Figure 8 is a view similar to that of Figure 6 showing the structure of Figure 1 mounted in a third manner on a supporting wall; Figure 9 shows an example of a bipod of the structure of Figure 1; and Figure 10 is a perspective view of a known form of supporting structure. Referring to the drawings, Figure 1 shows a supporting structure in the form of shelving having a frame comprising hollow section side members 11 to 14 and corner members 3 to 6. Each corner member has two protrusions 31, 32; 41, 42; 51, 52; and 61, 62 which extend at right angles to one another and engage in open ends of the side members to form the frame. Each side member 11 to 14 is formed with an axial slot 112, 122, 132, 142 along its base into which supporting brackets 7 are slotted, the supporting brackets being retained in the slots by guide flanges 71, 72 such that the brackets 7 are slidable along the length of the side members. Each bracket has a protruding flange 73 which extends at right angles, the bracket being generally L-shaped or flat as shown in Figures 3 and 4. The inner lower portion of each side member 11 to 14 is provided with an axially extending notch, 113, 123, 133, 143 into which metal grills 21 or the like are slotted during assembly of the shelving, the grills forming a base of the shelving. A respective slide member 101, 102 is slidably located in the slot 112, 132 of opposing side members 11, 13, the slide member having a securing block 1011, 1021 extending from the bottom thereof. A bipod comprising two generally U-shaped tubular members 8, 9 has securing holes 811, 911, 821, 921 provided at the free ends of side bars 81, 91, 82, 92 of the tubular members 8, 9, and a plurality of projecting lugs 912, 922 provided as shown on the side bars 91, 92 of tubular member 9. The lugs 912, 922 are uniformly spaced along the side bars. Each tubular member may be formed from tubular sections as shown in Figure 9. When assembling the structure to the form shown in figure 5, the grills 21 are slid into the notches, 113, 123, 133, 143 in the frame side members 11 to 14 to form the base 2 and the side members 11 to 14 are joined together using the corner members 3 to 6, thus forming the body 1 of the shelving. The lower, larger diameter end 151 of a respective pillar 15 is located vertically into a co-operating hole in the upper surface of each corner member 3 to 6. Cross members 154 are then located on the other, smaller diameter ends 152 of adjacent pairs of the pillars 15 by means of through-holes 1541 adjacent the ends of the cross members such that the two cross members 154 extend parallel to one another along the longer sides of the shelving. The two cross members are supported above the side members 11 to 14 by the shoulders 153 formed on the pillars 15 at the junctions of their larger and smaller diameter portions. Further cross members 155 are located in a similar manner on adjacent pairs of pillars 15 along the shorter sides of the shelving. The guide flanges 71, 72 of two or more brackets 7 are located in the slot 122 of one frame side member 12 and are secured to the side member 12 by means of screws passing through the projecting flange 73 and engaging in holes 114, 124, 134, 144 in the side member. Slide members 101, 102 are located in the slots 112, 132 of the shorter side members 11, 13 and the free ends of the monopod 8 are threadably engaged with holes 1011 in the securing blocks 1011, 1021 of the slide members 101, 102 with the free ends of monopod 9 threadably engaged to holes 10211 in the securing blocks 1011, 1021. In use of the shelving as shown in Figure 6, the brackets 7 are fixed to the upper free edge of the balcony enclosure or railing. The monopod 8 is then located between adjacent pairs of lugs 912, 922 on the monopod 9, the particular pairs of lugs being chosen such that when the lower end of the monopod 9 bears against the balcony enclosure or railing the shelving is supported in a substantially horizontal attitude. The position of the slide members 101, 102 relative to the frame side members 11, 13, can be altered utilizing the holes 114, 134 and the engagement of the monopods 8 and 9 adjusted to take account of variations in the type of balcony enclosure or railing to maintain the shelving in a substantially horizontal attitude. In addition, with an enclosure having a window frame, the supporting brackets 7 shown in Figure 7 can be used to secure the shelving to the balcony enclosure outside the window frame. The bracket 7 illustrated in Figure 8 can be used to secure the shelving to the side of a wall.
