SHEET 2 HF I 1 FURNITURE UNIT r FIELD on THE INVENTION The invention relates to furniture units including a table a plurality of chairs.
SUMMARY OF THE INVENTION According to the present invention, there is provided a furniture unit including a table, and a plurality of chairs each having a seat part, the table comprising a circular table top, and a column supporting the table top, the cross-section of the column being reduced substantially at the level of the seat parts of the chairs, and each chair comprising a continuous wall defining the seat part, a back part, and a supporting parts, the height of the back part being less than the height of the table top, whereby the chairs can be accommodated beneath the table top, the upper edges of the back parts being arcuate and having a radius not larger than that of the table top, and the side edge of each chair being contained within two inclined planes, whereby the chairs can be arranged around the column and beneath the table top with the seat parts lying adjacent the reduced section of the column.
The upper edges of the back parts can be centered on the line of intersection of the plane and can have a radius substantially equal to the radius of the table top.
Each chair can have two flanges extending from the upper edge of the back part and lying on opposite sides of the seat part.
The supporting part of each chair can be formed by double curvature front and side wall portions, the front wall portions being concave in horizontal cross-section, and being located rearwardly with respectto the front edges of the seat parts. The double curvature of these wall portions serves to stiffen the continuous wall.
BRIEF DESCRIPTION OF THE DRAWINGS An embodiment of the invention will now be described, by way of example only, with reference to the accompanying schematic drawings, in which:

FIG. 5 is a plan view of the chair; FIG. 6 is a side elevation of the chair;
FIG. 7 is a plan view partially in section showing sev- Y eral chairs in position beneath the table table (three of them being visible in the cut-away'right-hand half of the table);
FIG. 8 is a section showing the arrangement of FIG. 7; and
FIG. 9 is a perspective view of the unit showing some chairs located beneath the table and one chair withdrawn from the table. I w
DESCRIPTION OF THE PREFERRE EMBODIMENT As shown in FIGS. 1 to 3, a table of the furniture unit comprises a central column 1 supporting a circular table top having a working surface 3. Externally, the column 1 has a concave profile developed so as to have a restricted section in an intermediate position substantially at the level of the seat part of a chair 5. The lower end portion of the column forms a base 1A, having a circular profile, andthe upper end portion of the column forms a rim 1B engageable against an annular abutment 3A on the underside of die table top to which the column can be firmly connected.
Along the outer surface of the column I extend tapered ribs 1C which are enlarged at their end portions to be joined with the base 1A and the rim 1B. The column, as can be seen in FIG. 3, is hollow and is fonned by a relatively thin wall, which can be reinforced by means of an intermediate partition 1E, which may be used as a container. The table top can carry a pivot for a rotatable disc-shaped tray.
The chair seatc is illustrated in detail in FIGS. 4 to 6, and is formed with a continuous wall of a substantially uniform thickness and shaped with rounded corners, projections and recesses so as to define a back part 5A with a substantially horizontal upper edge 5B, provided with an outer arcuate convex rim 58 The back part 5A is formed with a portion of large curvature joined to a seat part 5C, whose development in plan cambers, form of an are also ceere long the lie 7,c has a convex front edge portion SE of a relatively large curvature and lateral edges 5E. 79
From the edges 5E, 5E there extends a supporting and base portion of the chair, which is in the form of a continuous wall having portions of different curvature to define a front wall 5F which isslightly concave with a double curvature, corner portions 5F, flanking the front wall 5F and side walls 5F also having a double curvature and being developed continuously from the edges 5B,.
The side walls 5F carry, at their rear edges, relatively wide flanges 5H which extend to the sides of the upper edge 53 of the back part, the flanges 5H being divergent from one another and being inclined rearwardly to ensure a firm supporting polygon for the chair.
The sides of the chair are contained within inclined lateral planes 7A which intersect along a line 78. When the table is to be used with six chairs, as shown in one half of FIG. 7, where three of the chairs appear, the planes 7 are inclined at 60; the center of curvature of the rim 5B, lies along the line 78 and. the lower edge of the front wall SE is in the form of an are also cen tered along the line 7B, the radius of curvature of this latter lower edge being not less than that of the base 1A of the column 1.
Of the described structures, at least those of the column l and of the chair can be formed by means of a hot molding process, using solid or expanded synthetic resins, or by means of other techniques such as a cold molding process using a polyester resin subsequently reinforced by glass fibers. The table top can also be formed using any one of the foregoing processes, or by other processes. According to the quality of the material, the thicknesses, the chambers, the flanges and ribs can be differently accentuated. The flanges 5H also impart strength to the side walls SP The height of the back part 5A is such that it can be I wall SP is arranged to lie adjacent the edge of the base 1A. said chairs 69 Under these conditions six chairs can be accommodated under and around the table, each occupying a volume contained within the planes 7A inclined at 60, the planes 7A containing the lateral surfaces of the flanges H and the edges 5E, and extending tangentially with respect to the edge 5E.
The flanges 5H of two adjacent chairs arranged beneath the table top are thus contiguous so as to form together a rounded rib, the bottom portion of which can extend outwardly below the edge of the table top. When the chairs are accommodated under the table top, the unit occupies a space which is practically equal to the volume bounded within the table top.
What is claimed is:
1. A furniture unit comprising a table including a circular top and a substantially central column supporting the latter, and a plurality of chairs, each of said chairs having continuous wall means defining respective seats, backs and supports, said column having a reduced section substantially at the level of said seats, the height of said backs being less than that of said table top, whereby said chairs can be accommodated beneath said table top, the upper edges of said backs being arcuate and having a radius not larger than that of said table top, and the side edges of said chairs being contained within two inclined planes, whereby said chairs can be arranged around said column and beneath said table top with said seats adjacent said reduced section of the column.
