Definitions

  • the present invention relates to furniture and, in particular, chairs in which the backrest is formed from an assembly thereby permitting standard parts to be used in chairs having different appearances.
  • a backrest assembly for a chair having a seat and a backrest, said assembly comprising a quasi-annular frame having a central opening therein, said frame defining the and peripheral rim of said backrest/the perimeter of said frame being shaped to conform with the intended perimeter of said backrest, said central opening comprising a substantial portion of said backrest and being adapted to receive a decorative insert therein to substantially close said opening, said insert being located approximately flush relative to said frame, and said assembly including means to secure said insert to said frame, whereby a number of inserts each one different to the other can be assembled with a corresponding number of identical frames to provide a corresponding number of backrests each of which has a different appearance.
  • the backrest assembly of the preferred embodiment is intended for use with a chair having tubular metal legs, the rear legs being extended upwardly to provide a support for the backrest.
  • a chair is that disclosed in U.S. Patent No. 3,722,954 assigned to the assignee of the present invention.
  • the backrest itself comprises a quasi-annular frame 1 which is approximately oval in shape and has two cavities 2 which are adapted to receive the upper portion of the extensions of the rear legs of the chair.
  • the frame 1 can be secured to the rear legs (not illustrated) by means of fasteners passing through the frame 1 and into the cavities 2.
  • the frame 1 is preferably moulded in an injection moulding process using high impact polystyrene or polyproplyene.
  • the perimeter 3 of the frame 1 is shaped to conform to the periphery of the backrest and a central opening 4 is provided, the central opening 4 being adapted to receive an insert which completes the backrest.
  • the inner surface of the frame 1 is provided with a lip 5 and a plurality of spaced recesses. It will be apparent to those skilled in the art that the frame 1 illustrated in Figs. 1 and 2 is a strong member and is easily able to withstand the loads applied to it by a person sitting on a chair.
  • FIGs. 3 to 5 the first embodiment of an insert 8 suitable for location within the central opening 4 of the frame 1 is illustrated.
  • the insert 8 is again moulded from high impact polyproplyene or polystryrene in an injection moulding operation and, as seen in Fig. 3, is moulded with a cane pattern on both the outer surfaces of the insert 8.
  • the insert 8 is shaped to provide a comfortable surface for the sitter and is also shaped to co-operate with the central opening 4 to substantially fill same.
  • the insert 8 is retained within the central opening 4 by means of a plurality of tongues 9 which co-operate with recesses 6.
  • each tongue 9 carries a protrusion 10 at the free end thereof which, when the insert 8 is placed into the central opening 4,is located in the corresponding recess 6. It will also be seen that the free end of each tongue 9 abuts the lip 5 of the frame 1. It will be apparent to those skilled in the art that the insert 8 may be easily located within the central opening 4 by means of a single assembly operation and that the insert 8 cannot easily be removed from the frame 1 because of the inter-engagement of the protrusions 10 with the recesses 6.
  • Fig. 7 is a view similar to that of Fig. 6 showing the inter-engagement of an insert 12 of a second embodiment.
  • the insert 12 of Fig. 7 is intended to be upholstered and accordingly has slightly smaller overall dimensions than insert 8 so as to provide a gap 13 between the tongue 9 of the insert 12 and the frame 1. It will be appreciated by those skilled in the art that when the insert 12 is upholstered the gap 13 is substantially filled by the upholstery material. Furthermore, the insert 12 is upholstered prior to insertion into the central opening 4 of the frame 1.
  • FIG. 8 to 10 inclusive A third embodiment of the present invention is illustrated in Figs. 8 to 10 inclusive in which a further insert 15 is provided, the insert 15 being characterised by the provision of slats 16 regularly spaced across the insert 15.
  • the slats 16 provide strength for the insert 15 yet permit air to pass. from behind the backrest directly to the back of a person sitting in the chair. Again the inter-engagement between the insert 15 and slats 16 is by means of tongues 9 and recesses 6.
  • the frame 1 may be combined with any one of the inserts 8, 12 or 15 so as to produce one of three different backrests. In this way a relatively small number of mouldings may be used to produce an output having a large variety of combinations and in this way the cost of moulding for each combination is significantly reduced.
  • the tongues can be located on the frame and the recesses on the insert.
