Metal table structure

Abstract

 A metal table structure comprising a polygonal panel (2) and a plurality of legs (4), characterised in that the edges of said panel are bent at 90° and form at the corners, together with brackets (12) secured to said edges against the lower surface of the panel, seats for the insertion of the upper ends of said legs, fixing means (24) being provided to simultaneously engage said brackets, said legs and an element (28) which elastically urges said bracket against said leg.

Description

[0001] This invention relates to a metal table structure.

[0002] Metal table structures are known comprising four legs, to the upper ends of which there are applied, by means of screws and/or bolts, longitudinal members and cross members to which a panel is then fixed, again by screws and/or bolts. To give the structure a certain stability, a further panel is fixed to the lower part of the legs.

[0003] However, these known table structures have certain drawbacks, and in particular:

• laborious assembly due to the presence of the various components to be fitted together,
• substantial manufacturing cost, on account of the various operations involved.

[0004] An object of the invention is to eliminate these drawbacks by providing a table structure of considerable stability which can be assembled in a simple and comfortable manner.

[0005] A further object of the invention is to provide a table structure formed from a small number of components and fixing elements.

[0006] These and further objects which will be apparent from the ensuing description are attained according to the invention by a metal table structure as described in claim 1.

[0007] The invention is described in detail hereinafter with reference to the accompanying drawings, on which:

Figure 1

Figure 2 and 3

are profile sections of the edges of the structure panel,

Figure 4

is a partial exploded perspective view of the table structure in correspondence with a leg, and

Figure 5

is a perspective view of the table structure in its assembled state.

[0008] As can be seen from the figures, the table structure of the invention comprises substantially an upper panel 2 supported by four tubular legs 4 of substantially square cross-section, and a lower panel 6 secured to the four legs.

[0009] The upper panel 2 is prepared by bending a metal sheet in a press to form a profiled bent edge defining a stepped portion 8 to which, at the corners, there is welded to its vertical surfaces 10 a W-shaped bracket 12 provided with holes 14. At the corner, the internal portions 16 of the W-shaped brackets 12 define, together with the vertical portions 10 of the panel edges, seats for the insertion of the upper ends of the legs 4. On the inside of the upper ends of the legs 4 there are welded angle pieces 18 provided with threaded holes 20 facing corresponding holes 22 provided in the legs.

[0010] To ensure stability to the structure, the panel 2 is fixed to the legs by screws which successively engage the holes 26 provided in C-shaped plates 28, the holes 14 of the brackets 12, the holes 22 of the legs 4, and the holes 20 of the angle pieces 18.

[0011] The particular C shape of the plates 28 provides a greater area for clamping the leg to the panel and a certain elasticity.

[0012] The panel 6 also has bent edges which in correspondence with each corner present a recess of right-angled isosceles triangular section having the width of its sides equal to the width of the sides of the legs so that these can be housed within said recess.

[0013] The two continuous surfaces 32 provided by the recess comprise two vertical slots 34 and are welded to W-shaped strengthening plates 36 also comprising slots 38.

[0014] This panel is fixed to the legs by firstly inserting screws through holes 42 provided in the legs, to engage via their projecting ends in bushes 44, onto which the slots 34 and 38 are then hooked to form a connection.

[0015] From the aforegoing description it is apparent that the metal table structure of the invention has considerable advantages, and in particular:

• it has considerable stability by virtue of the joint formed by the upper panel and the upper ends of the legs,
• because of the structural function of the upper panel, it enables the lower panel to be fixed by simple hooking-on.

Claims

1. A metal table structure comprising a polygonal panel (2) and a plurality of legs (4), characterised in that the edges of said panel are bent at 90° and form at the corners, together with brackets (12) secured to said edges against the lower surface of the panel, seats for the insertion of the upper ends of said legs, fixing means (24) being provided to simultaneously engage said brackets, said legs and an element (28) which elastically urges said bracket against said leg.

2. A metal structure as claimed in claim 1, characterised in that the panel is shaped as a right-angled parallelogram.

3. A metal structure as claimed in claim 1, characterised in that said bracket (12) is shaped substantially as a right-angled W.

4. A metal structure as claimed in claim 1, characterised in that said element (28) consists of a plate substantially of C-shape.

5. A table structure as claimed in claim 1, characterised in that angle pieces (18) are welded on the inside of the upper ends of the legs.

6. A metal structure as claimed in claim 1, characterised by comprising a lower panel (6) with bent edges, each corner presenting a recess of right-angled isosceles triangular section having the width of its sides equal to the width of the sides of the legs.

7. A metal structure as claimed in claim 6, characterised in that the recessed portions are provided with slots (34) for hooking onto corresponding pins (40) engaged in the legs.

8. A table structure as claimed in claim 6, characterised in that a strengthening plate (36) is welded onto the inner side of the bent edges of the recess.

9. A metal structure as claimed in claim 1, characterised in that said fixing means consist of threaded screws which pass successively through the elements (28), the bracket (12), the legs (4) and the angle pieces (18).
