Shelving and display systems and the like
BACKGROUND OF THE INVENTION 
     The present invention relates to shelving systems, display systems and the like and, more particularly, to a bracket device for use in such systems. 
     SUMMARY OF THE INVENTION 
     The invention consists in a bracket device for a shelving or display system, comprising a body having a plurality of recesses disposed in and about the periphery of the body with their axes substantially parallel, said recesses being open at both ends of the body, and a support member for supporting an element of the shelving or display system from the body comprising a body-engaging part and a projecting part, said body-engaging part being slidable into a selected recess via either one of said open ends thereof with the projecting part projecting from the periphery of the body, said body-engaging part and the body having cooperating means to retain the support member in the recess when the support member is inserted therein. 
     Preferably, each of the recesses is of generally part-circular shape and subtends an angle of more than 180° at its axis so as to have a mouth which is of restricted width at the periphery of the body. The body may, for example, have eight such recesses. The body-engaging part of the support member may be part-circular in cross-section and may be tapered to facilitate sliding it into a recess. 
     The recesses may be disposed at equally spaced positions around the body in a generally circular array. The body and/or support member may be moulded of a plastics material. 
     The invention also consists in a shelving or display system comprising uprights, one or more bracket devices as described above, and shelving or display elements mounted on the uprights by means of said bracket devices, wherein the body of the or each bracket device is secured to one of the uprights, the projecting parts of the support members are secured to or engage said elements, and the body-engaging parts of said support members are disposed in selected recesses of the bodies secured to the uprights.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to FIGS. 1 and 2 a panel display system comprises epoxy coated steel tubular uprights 1 mounted on pedestals or feet 2, and styrene display panels 3 supported between adjacent uprights 1 by means of bracket devices 4, which will hereinafter be more fully described with reference to FIG. 7. 
     In this display system each foot 2 is of a shell construction which is filled with plaster or other heavy material so that the uprights cannot easily be knocked over. 
     FIGS. 3, 4, 5 and 6 illustrate a shelving system comprising four tubular uprights 1, four shelves 10 supported by respective bracket devices 4 mounted on the uprights 1, and horizontal tubular frame members 5, 6, 7 and 8 extending between uprights 1 and adjacent to the edges of shelves 10. In this embodiment the uprights 1 are shown mounted on light plastics feet 9 which are screwed into the bottoms of the uprights. 
     Each bracket device 4, as shown in FIGS. 6 and 7, comprises a generally cylindrical body 11 and one or more support members 12. The body and support members are formed as plastics mouldings. The body 11 has eight part-circular recesses 13 disposed at equally spaced positions around the body 11 in a generally circular array. These recesses are open at opposite ends and are disposed in and about the periphery of the body with their axes substantially parallel. Each recess subtends an angle of more than 180° at its axis so that it has a mouth 14 which is of restricted width at the periphery of the body. 
     The support member 12 comprises a body-engaging part 15, and a hollow projecting part 16. The body-engaging part 15 is part-circular in cross-section and is tapered to facilitate sliding it into a selected recess 13 via one of its open ends and, when the part 15 is inserted into a recess, the projecting part 16 projects from the periphery of the body 11 through the mouth 14 of the recess. In order to prevent the body-engaging part passing through the recess the body-engaging part 15 has a shoulder 17, adjacent its larger end, which abuts a corresponding shoulder 18 provided around the wall of each recess 13 thereby to retain the body-engaging part in the recess. In the present embodiment each recess 13 has two shoulders 18, adjacent opposite open ends so that the body-engaging part 15 can be introduced into a recess via either end and be retained therein in the same manner. 
     The support member 12 also has an intermediate flange 19 between the body-engaging part 15 and the projecting part 16. Portion 19 is wider than the mouth of each recess 13 and when the body-engaging part 15 is located in a recess 13 the edges of the portion 19 abut the periphery of the body 11 on opposite sides of the mouth 14 to provide additional support. 
     The manner in which a bracket device 4 is fixed to a tubular upright is shown in FIG. 6. Each tubular upright consists of a plurality of individual tubular members only two of which 1a and 1b are shown in the Figure. The lower end of tubular member 1a is internally threaded and is screwed onto the threaded end of a stud 20 which extends into the upper end of tubular member 1b. A nut 21 is screwed onto the inner part of the threaded end of stud 20 and is located between the lower end of tubular member 1a and the upper end of tubular member 1b. The body 11 of each bracket device 4 has a central hole 22 through which tubular member 1a extends. The body 11 is supported by the nut 21 which rests in an annular recess 23 disposed in the bottom of the body 11 around the central hole 22. 
     FIG. 8 illustrates a modified form of fixing for the body. In this modification the body has a smaller diameter central hole 23 than in FIG. 6. The nut 21 is omitted and the body 11 is clamped between the lower end of tubular member 1a and the upper end of tubular member 1b so as to fix it to the tubular upright. 
     The body-engaging part 15 of a support member is shown in FIG. 5 located in one of the recesses 13. In order to support elements of a display or shelving system such as panels 3, shelves 10 or frame members 5, 6, 7 and 8, the projecting parts 16 may be secured to these elements. In FIG. 1 the projecting parts 16 of the support members 12 are secured in the side edges of the panels 3. In FIG. 5 the shelves have cut-off corner parts 10a each of which is disposed adjacent a respective bracket device 4. Here the projecting parts 16 are secured in the edges of the cut-off corner parts 10a of the shelves. In FIG. 6, the projecting part 16 of the support member 12 is inserted in and secured in the adjacent end of the tubular frame member. 
     Whilst particular embodiments have been described it will be understood that modifications can be made without departing from the scope of the invention. For example, the projecting parts 16 of the support members 12 need not be positively secured to the elements which they support, but may merely act as supports. For instance each of the cut-off corners 10a of the shelves 10 may merely rest on projecting part 16. 
     Furthermore, in a preferred modification bracket body 11 may be provided with a smaller central hole so that it may be fitted over the threaded end of stud 20 and be trapped between the upper end of lower tube 1b and the lower end of upper tube 1a into which stud 20 is screwed. The nut 21 is omitted from this position but may be used on feet 9 as a lock nut at the bottom of the tubular uprights. The nut may also be screwed onto the stud associated with the topmost bracket body on each upright to secure the body thereto.
