Definitions

  • the present invention relates to support bases, for instance, for chairs, tables, display stands or other free standing articles of furniture.
  • a freestanding article of furniture such as a chair or table
  • This support base may be of various forms. For instance it may comprise a central portion to hold the supporting column. Disposed radially around the central portion may b3 a plurality of leg members which are intended to distribute the weight of the central supporting column and its associated article of furniture and so to balance and hold the article of furniture in a stable position.
  • a support base has been made out of aluminium.
  • a support base comprising a single plastics moulding, said base having a hub portion for locating a column extending downwardly from a chair seat or other structure, and, extending substantially radially outwardly and downwardly from said hub portion, a plurality of leg members, said leg members being for engagement, at their ends remote from the hub portion, with the ground or with ground-contacting elements such as castors.
  • each leg member is of substantially U-shaped section. More preferably each leg member includes along its length a portion which is of substantially E-shaped section.
  • the hub portion comprises a hollow cylindrical portion. More preferably the hub portion includes an inner hollow cylindrical portion and an outer, coaxial and concentric hollow cylindrical portion, xaid portions being interconnected between adjacent upper ends thereof. Most preferably there are also inter-connecting radial ribs between the inner and outer hollow cylindrical portions.
  • the outer cylindrical portion inter-connects with the leg members by ribs extending substantially radially from the external surface of the outer cylindrical portion. More preferably some of the ribs should extend at least a part of the way along the length of each of the leg members.
  • the number of leg members is at least four. More preferably the number of leg members is five.
  • a support base 1 in accordance with the present invention is a single plastics moulding and comprises a central hub portion 3 with five leg members 5 extending substantially radially from the central hub portion 3.
  • a central region of hub portion 3 is a circular hole 7 into which a support column for an article of furniture such as a chair or table may be inserted.
  • hub portion 3 comprises an inner hollow cylindrical portion 9 and an outer hollow cylindrical portion 11. These are connected together at their respective top ends by the upper, substantially horizontal wall 12 of the support base and along their lengths by radially extending inter-connecting ribs 13. Extending radially outwardly from the outer surface of outer hollow cylindrical portions 11 are five radially extending equally spaced apart short ribs 14 which connect said outer hollow cylindrical portions 11 with portions of the plastics moulding lying between adjacent leg members 5.
  • Each leg member 5 includes a major central portion 15 of E-shaped section.with the central rib 17 extending from hub portion 3 to a position 16 located a short distance radially inwardly of the outer extremity of the leg. Rib 17 inter-connects from its end at position 16 with the outer vertical walls 18 and 20 of leg member 9 by means of short ribs 22 which are inclined at an angle with respect to the longitudinal axis of leg member 5. Somewhat similar inclined short ribs 24 extend between rib 17 of each leg member 5, from a position approximately one third of a distance along the rib from the outer surface of hollow cylindrical portion 11, to that portion of the moulding inter-connecting leg member 5 in question and an adjacent leg member.
  • Each rib 17 can be considered to extend from position 16 near the outer extremity of leg member 5 to outer cylindrical portion 11 and to continue from portion 11 through to inner hollow cylindrical portion 9 by means of an appropriate one of the inter-connecting ribs 13. Indeed, although each inter-connecting rib 13 extends vertically downwardly to the bottom 26 of cylindrical portions 9 and 11, and said cylindrical portions 9 and 11 project downwardly beyond the adjacent portions of the base as best seen in Figure 3, each rib 17 is shaped, adjacent outer hollow cylindrical portion 11 so as to curve downwardly to a position close to said bottom 26 of portions 9 and 11. These downwardly curved portions are shown at 28 in Figure 3.
  • each leg member 5 At the extreme end of each leg member 5 is a circular portion 19 in the middle of which is hole 21. Circular portion 19 projects below the bottom edge of the adjacent portion of leg member 5 and can either contact the floor directly of can have attached thereto a floor contacting element such as a castor.
  • the material used may be any suitable plastics material and construction may be by any suitable method.
  • the plastics material may be a glass fibre reinforced polypropylene resin containing approximately 30% glass-fibre.
