ABSTRACT OF THE DISCLOSURE
In a frame for assembling and uniting together the component parts of a piece of furni-ture such as a chair or a table, the combination of a rib-like corner piece, an inset and a wedge which cooperate with a profiled leg in such as way that, by placing set screws and dowels in the special-ly provided seatings, a unitary structure is obtained, which not only is endowed with the required robust-ness and rigidity, but it is also easy and convenient to dismember when so required or necessary.

Description
~047~9~ ~
This invention rela~es in general to a metal-lic framing for pieces of furniture~ and more.parti.eu-larly to the mutual fastening of the component parts which are adapted to ~ake up framings of the ktnd referred to above.
The difficulty is kno~m to provide a nodal -point of a framing, which11s adapted to afford a great . stabiliity to the structure borne by said raming. This ~ :
. problem is felt particularly when manufacturing pieees :10 of furniture having a metallie structure~ when from the nodal point co-nponent parts depart which are not addition~
ally affixed to other struetures~ but are merely laid on~
for example on a flooring: thus, for example, the legs of a chair or of a table must be snugly affixed to their supporting plane not to have them negatively influencing ~ ~.
the function of the pieee of furniture concerned.
An object of the invention is to suggest a :~
metallic framing for pieces o furniture, the installa~
tion of which is easy, reliable and capable of being ~ .
easily performed without incurring the risk of obtaining an unstable or unsatisfactory stru.eture.
This object is achieved aecording to this invention : by a metallic framing~ more parti.cularly for chairs and tables~ which comprises profilecl sections adapted to make up a framing on a plane and legs to be affixed to ~
the frami.ng~ characterj.zed i~ that from every leg there :;
extencl longituclinal side str:ips which encompass two of said profiled component parts i.n the area in whieh they converge to provide an apex, said le~ beingr fastened to the apex by means of a wedge l~hich acts upon the pro-filed component parts on the s.ide away of said str:ips and through a junction corner piece the webs of whi.ch are inserted in header seats of the profllecl members ,, , ` .
~04~0~Z
wllich make up the apex~ the leg~ the corner piece and the wedge being mutually connected by set screws.
In a preferred embodiment of the invention~ the slopin~ surfaces of the wedge.have, each, a seating in which a dowel is received, which is passed through a bore of the wall of the seat oE the proflled component part which is inserted in a slot-like groove in~erted in the seating of the profiled component part.
With reference to the figures of the accompanying drawings, the invention will be better explained on the basis of a preferred embodiment thereof.
In the drawings : .
FIGURE 1 is an exploded view of a portion of a framing according to the in~ention~ and - FIGURE 2 shows a top view of the framing shown in FIGURE 1 in the position of installation. ~ -The framing according to the invention~ as shown ~:
in the drawings~ comprises proflled component parts 10 and ll, a corner piece or tab 12 for joi~ting the members 10 and ll~ a leg 13, a tightening wedge 14, a core or inset 15, set screws 16 and connection dowels 17.
Each component part 10, ll, at its end, is equip-ped with a header seating 18, which is adapted to recei~e in a slidable manner either wi.ng 19 of the corner piece 12.
The two wings 19 of the corner piece 12 are per-; pendicular to one another an~1 are extended from a central portion 20 which is a~lapted to match the edges of the .
seatings 18. The portion 20 provides a counter-wedge to the wedge 14~ which with its sloping surfaces mates the ~urfaces of the two componenl; parts 10, ll adjoining the seatlngs 18~
The wedge 14 has a trapezoidal cross-sectlonal outline and has centrally passing bores 21 which correspond , ............ . . . . . .
,~ ~ . , .
~70gZ
to hores 22 of the portion 20 ancl to bores 23 of the leg 13.
The bores 23 of the leg 13 are formed through a wall 24 of an end seating of the leg 13 adapted to receive the insev 15 which is equi.pped in its turn with tapped holes 25 in which the screws 16 are screwed.
The wall 24 is intended to mate the outer surface of the portion 20. In addition~ from the leg 13 longitu-dinal strips 32 are ex-tended~ which are mutually perpendi-cular and are adapted externally to encompass the end ~ --areas of the COmponent parts 10 and 11. .
In a bottom extension of the portion ~0~ more-over~ a bore 26 is provided, which can be put in align-ment with a bore 27 of the wall 24 and with a tapped hole 28 provided in the inset 15.
Through each sloping face of the wedge 14 a blind hole 29 is providecl whlch gives a seat to a dowel 17, the latter being adapted;to be inserted, in addition, into a bore 30 of the seat 18 and in a slot-like ~roove 31 of the wing 19.
The mutual arrangement of the bore 30 and the groove 31 is such that the dowel 17 inserted iII the bore 30 is allowed to slide within the groove 31 between a position where the wing 19 is withdrawn from the seating 18 an~1 a posi.tion where the portion 20 abuts the eclges of the seating 18.
The assemblage of a framing according to the in-vention is carried out as follows .
The wings 1~ are inserted in the seatings 18 and bring the groove 31 in correspondence with the bore 30.
The do~els 17 are then inser-ted through the bore 30 into the groove 31. The correct positioning for inserting the dowels 17 is acljusted by having the wings 19 to s:Lide the seating6 18 so that the dowels 17 are brought at a dis-:

tance wl-ich is correct just or being inserted in the blind holes 29 cf the we(lge 14. The latter is then pushed towards the members 10 and ll and cause the com-plete en-trance of the wings 19 into the seatings 18 as the sloping faces of the same wedge contact the members 10 and 11.
~ t this stage, the leg 13 with the inset 15 in the seating~ with its wall 24 poin*ing towards the portion 20 is brought with the strips 32 contacting the members 10 and ll; the bores 21~ 22~ 23 and 25 must be very cor-rectly aligned so that the screws 16 can be inserted from the side of the wedge 14 to be screwed in-to the bores 25 of the inset 15.
Simul-taneously~ also the bores 26~ 27 and 28 are aligned so that in the latter bore a screw can be tighte-ned (not shown ), which is inserted from the side of the portion ~0.
In the way just now described a stable structure is provided without having -the tightening of the legs to the frame prejudicing the stablity of same structure.
An incorrect assemblage has been rendered virtllally impos-sible~ in fact~ and so is a stress on material which would be susceptible of damaging it. Thus also the fastening system according to the invention makes possible a take~
up of the clearances which often occur between the leg and the framing and which make the supported structure unstable~ such as for example a table.
Of course, the componen-t parts and the fastening members as described above could also be differently shaped. Thus the fastening members could also connect with any corner the profiled components which make up the framing of the resting plane, rather than at right angles as described herein.
It should be noted that the assemblage of the ~ . . . . .. . .
