ABSTRACT OF THE DISCLOSURE
This invention relates to furniture for sitting down, made of plastics material, said furniture compri-sing a plurality of components, viz. two sides and at least one shell, connection of two components together is ensured, at the front and at the rear, by an assembly stud integral with one of the compo-nents, extending in lateral projection upwardly and cooperating by fit with an assembly housing in the other component which opens out downwardly for the penetration, by slide in a vertical plane, of the front and rear assembly studs, a screw passing upwardly through each stud and screwing in a hole in said other component.
Description
Z~ 3~i FIELD OF THE INVENTION
The present invention relates to furniture for sitting down, made of plastics material, of the type comprising two sides and at least one shell assembled and fixed to one another.
sACKGROUND OF THE INVENTION
The means for assembling and fixing such known furniture are constituted by journals projecting perpendicularly to the inner face of the sides and 10 penetrating horizontally in holes in the shell which open out on the edge thereof, such fit being completed by a fixation made inside the shell by means of a screw.
This mode of connection presents the drawback 15 of not being sufficiently rigid and of becoming loose with use, so that the furniture very quickly becomes unsound.
Furthermore, it is not suitable for joining two contiguous shells when the piece of furniture 20 is a bench. Consequently, it is necessary to provide longitudinal bars completing the structure, which bars render the furniture heavy, increase the cost price thereof and are unaesthetic.
Moreover, the mould provided for making the 25 shell is relatively complicated, being given that it must comprise mobile parts to make the holes in the edges.
In addition, assembly is inconvenient as access to the screws and manoeuvring thereof are difficult.
Finally, the shell cannot be used independently of the sides as armless seat, without the addition of mouldings on the edges to conceal the holes.
It is an object of the present invention to' overcome these drawbacks by proposing a particular 35 mode of connection whereby the rigidity of the piece 2~)~6~36 of furniture is considerably improved between shell and side, as well as between two contiguous shells without the addition of bars; whereby the manufacturing moulds are also simplified; the fixing screws are easily accessible; the shells have a finished appea-rance, and the piece of furniture is veritably modular in that the same modules are suitable whatever the length of said piece of furniture.
SUMMARY O~ THE INVENTION
To that end and in accordance with the invention, the connection of two components (sides, shells, ...) together is ensured, at the front and at the rear, by an assembly stud integral with one of the components, extending in lateral projection upwardly 15 and cooperating by fit with an assembly housing in the other co~ponent which opens out downwardly for the penetration, by slide in a substantially vertical plane, of the front and rear assembly studs, a screw passing upwardly through each stud and screwing in 20 a hole in said other component.
If the direction of unmoulding of the or each shell which extends obliquely with respect to the seat element and the backrest is considered, the front and rear assembly housings of this shell advan-25 tageously present walls inclined substantially inthe direction of unmoulding to allow fit in this direction of the conjugate assembly studs integral with the component to be added.
According to a first embodiment, the front and 30 rear assembly studs are moulded on each side and project on the inner lateral face thereof.
According to a second embodiment, each assembly stud projects on a moulded part also comprising in projection, in a perpendicular direction, a positi~ning 35 stud adapted to be fitted in a housing for receiving Z~)~693~
the component to be equipped and to be fixed therein by means of a screw, these studs being oriented with respect to one another so that, the two components to be connected being suitably disposed, the assembly stud is located opposite the corresponding assembly housing.
Whatever the embodiment chosen, two twin assembly studs are integral with each of two intermediate rear and front legs, these twin studs being adapted to be fitted and fixed in the assembly housings of two contiguous shells.
Furthermore, in order to improve rigidity, each assembly stud is connected to its support (side, added piece or intermediate leg) by a shoulder adapted to bear against the component defining the assembly housing con,ugate with this stud; each positioning stud is connected to the added part by a shoulder adapted to abut on the component defining the receiving housing conjugate with this stud; the studs have sloping faces in order to wedge in their housings.

DETAILED DESCRIPTION OF THE DRAWINGS
Referring now to the drawings, and firstly to Figures 1 to 3, the piece of furniture for sitting down, whether it be an armchair or bench, is an assem-bly of a plurality of modular components of injected moulded plastics material. The armchair (Figure 1) comprises a shell l connected with two symmetrical sides 2 and 3. The bench (Figures 2 and 3) comprises two identical shells l joined together by an interme-- diate rear leg 4 and an intermediate front leg 5, as well as with two symmetrical sides 2 and 3.
Shell l is monolithic and comprises frame elements 6, 7 which are lateral sections between which extend substantially horizontal laths 8 to constitute the seat element, as well as crosspieces 9 joined~by upright laths l0 to form the backrest.
Sides 2 ar;d 3 present the shape of a bow of which the branches constitute a straight front leg ll and a concave rear leg 12 joined together, above the level of the seat element, by a rounded part 13 extended rearwardly by an armrest 14. Of course, sides 2 and 3 may take any other appropriate shape as aesthetically desired, as long as the connection 6~3fi _5_ means recommended hereinafter can be employed.
As shown clearly in Figures 4 to 6, the connection of each shell 1 with a side 2 or 3 is ensured by means of assembly studs 15 and 16 cooperatlng with assembly housings 17 and 18.
The assembly studs 15 and 16 are integral with legs 11 and 12 respectively, being spaced apart there-from and extending upwardly in projection on their inner face. The assembly housings 17 an~ 18 are defined 10 by partitionings of the corresponding frame element 6 or 7 of the shell.
As shown in the example illustrated in Figure 4, the axes 19 and 20 of the housings 17 and 18 are advantageously parallel to direction F of demoulding 15 of the shell, i.e. to the direction in which the two parts of the mould are spaced apart from one another to release said shell from the impression defined by said parts. In this way, the longitudinal partitions 21, 22 and 23, 24 of housings 17 and 18 20 which are in that case substantially parallel (to within the draft of demoulding or the slope of wedging which are mentioned hereinafter) to the direction F, demould easily.
In the example shown, the assembly studs 15 25 and 16 are U-sections whose cross-section may be inscribed in a square for the rear legs 12 and in a rectangle for the front legs 11, which cross-section corresponds substantially to that of the housings 17 and 18.
The longitudinal partitions 21 to 24 are therefore with flat contact parallel to axes 19, 20 and perpendi-cular to the plane defined thereby. A slope slightly greater than the draft of demoulding may be provided on these partitions which consequently, by cooperating 35 with the flanges of the studs 15, 16 in conjugate 2~ 936 slope, cause wedging thereof.
As the sides are relatively large, geometrically deformable moulded parts, the relative positioning of the studs 15 and 16 is not strictly the same for all the sides. Under these conditions, the partitions 21 to 24 are located so that only two of these parti-tions may bear against the flanges of the studs 15 and 16 when these studs are completely fitted in the housings 17 and 18, a slight clearance in that 10 case appearing between the other two partitions and said studs.
The housings are also defined by antero-posterior partitions 25 to 28 extending parallel to the plane defined by axes 19 and 20. They are sloping and spaced 15 apart so that they all bear against studs 15 and 16.
According to a first embodiment (not shown in the drawing), the studs 15 and 16 are moulded with the sides. The mould must in that case comprise mobile 20 parts to allow demoulding.
According to a second embodiment illustrated in Figures 4 to 9, studs 15 and 16 project on moulded parts 29 and 30 respectively. These parts also comprise in projection, in a perpendicular direction, positio-25 ning studs 31 and 32. The latter have a tubular shapeof rectangular section complementary to that of recei-ving housings 33 and 34 respectively defined by the corresponding side 2 or 3. These housings are very easy to obtain, being given that the sides are demoul-30 dable perpendicularly to their lateral faces andthe housings may be demoulded in the same direction, the mould half simply presenting fixed projections at the location thereof.
Studs 15 and 31 are, of course, oriented with 35 respect to one another so that, taking into account _7_ Zl~6 ~3 6 the location of the receiving housing 33 in which the conjugate positioning stud 31 must be fitted, the assembly stud 15 is perfectly aligned with the assembly housing 17. Similarly, the studs 16 and 32 are oriented to take into account the locations of housings 34 and 18.
In order to fix parts 29 and 30 on corresponding' side 2 or 3, screws 35 and 36 pass through holes 37 and 38 made in the bottoms of the positioning 10 studs 31 and 32 and are screwed in holes 39 and 40 in the bo'.toms of housings 33 and 34 of the correspon-ding frame element 6 or 7 of the shell 1. Consequently, parts 29 and 30 are in1_egral with sides 2 and 3, the parts of one side being symmetrical to the parts 15 of the other side, in the same way as the sides are symmetrical with respect to one another. In this way, these sides 2 and 3 present, in projection, suitably oriented assembly studs 15 and 16.
To assemble the piece of furniture (Figures 20 1 to 3), the assembl studs 15 and 16 of each of the sides 1 and 2 are fitted in the assembly housings 17 and 18 of the corresponding frame element 6 or 7 of a shell 1. Screws 41 and 42 then pass through holes 43 and 44 made in the bottoms of the assembly 25 studs 15 and 16 and axe screwed in bushes 45 and 46 of the shell projecting in housings 17 and 18.
In order to improve rigidity of the connection of sides 2 and 3 with the shell 1, the assembly studs 15 ant~ 16 are connected to parts 29 and 30 or to 30 said sides when the latter are moulded with these studs, hy shoulders 47 and 48 (Figures 8 and 9) ensu-ring a wide bearing surface against frame elements 6 and 7 of the shell clnd thus improving the fits.
The same means may be employed for improving the 35 fixation of parts 23 and 30 on sides 2 and 3 and, -8~ 69~
to that end, the positioning studs 31 and 32 are connected to said parts 29 and 30 by shoulders 49 and 50 (Figures 8 and 9) ensuring a wide be.~ring surface against the sides and thus improving fits.
S Considering now the bench illustrated in Figure 2, it is important to recall that the two shells 1 are joined together and supported by an intermediate rear leg 4 and an intermediate front leg 5.
To ensure connection and as shown in Figures 10 10 and 11, assembly housings 17 and 18 of frame element 6 of the right-hand shell in Figure 2 and those of the frame element 7 of the left-hand shell are ~Ised to receive two assembly studs 16 integral with a cap 51 surmounting a leg 4 and, respectively, two assem-bly studs 15 integral with a c;ap 52 surmounting leg 5, fixing screws being positioned as before.
The means described heræinbefore ensure the rigid ~onnection of sides 2 and 3, possibly of inter-mediate legs 4 and 5, with the seat element 8 of shell 1.
The armrests 14 of these sides may also advanta-geously be fixed on the backrest 9, 10 of shell 1.
To that end, various means may be employed, and in particular a system incorporating studs and housings of the type mentioned above.
The present invention relates to furniture for sitting down, made of plastics material, of the type comprising two sides and at least one shell assembled and fixed to one another.
sACKGROUND OF THE INVENTION
The means for assembling and fixing such known furniture are constituted by journals projecting perpendicularly to the inner face of the sides and 10 penetrating horizontally in holes in the shell which open out on the edge thereof, such fit being completed by a fixation made inside the shell by means of a screw.
This mode of connection presents the drawback 15 of not being sufficiently rigid and of becoming loose with use, so that the furniture very quickly becomes unsound.
Furthermore, it is not suitable for joining two contiguous shells when the piece of furniture 20 is a bench. Consequently, it is necessary to provide longitudinal bars completing the structure, which bars render the furniture heavy, increase the cost price thereof and are unaesthetic.
Moreover, the mould provided for making the 25 shell is relatively complicated, being given that it must comprise mobile parts to make the holes in the edges.
In addition, assembly is inconvenient as access to the screws and manoeuvring thereof are difficult.
Finally, the shell cannot be used independently of the sides as armless seat, without the addition of mouldings on the edges to conceal the holes.
It is an object of the present invention to' overcome these drawbacks by proposing a particular 35 mode of connection whereby the rigidity of the piece 2~)~6~36 of furniture is considerably improved between shell and side, as well as between two contiguous shells without the addition of bars; whereby the manufacturing moulds are also simplified; the fixing screws are easily accessible; the shells have a finished appea-rance, and the piece of furniture is veritably modular in that the same modules are suitable whatever the length of said piece of furniture.
SUMMARY O~ THE INVENTION
To that end and in accordance with the invention, the connection of two components (sides, shells, ...) together is ensured, at the front and at the rear, by an assembly stud integral with one of the components, extending in lateral projection upwardly 15 and cooperating by fit with an assembly housing in the other co~ponent which opens out downwardly for the penetration, by slide in a substantially vertical plane, of the front and rear assembly studs, a screw passing upwardly through each stud and screwing in 20 a hole in said other component.
If the direction of unmoulding of the or each shell which extends obliquely with respect to the seat element and the backrest is considered, the front and rear assembly housings of this shell advan-25 tageously present walls inclined substantially inthe direction of unmoulding to allow fit in this direction of the conjugate assembly studs integral with the component to be added.
According to a first embodiment, the front and 30 rear assembly studs are moulded on each side and project on the inner lateral face thereof.
According to a second embodiment, each assembly stud projects on a moulded part also comprising in projection, in a perpendicular direction, a positi~ning 35 stud adapted to be fitted in a housing for receiving Z~)~693~

DETAILED DESCRIPTION OF THE DRAWINGS
Referring now to the drawings, and firstly to Figures 1 to 3, the piece of furniture for sitting down, whether it be an armchair or bench, is an assem-bly of a plurality of modular components of injected moulded plastics material. The armchair (Figure 1) comprises a shell l connected with two symmetrical sides 2 and 3. The bench (Figures 2 and 3) comprises two identical shells l joined together by an interme-- diate rear leg 4 and an intermediate front leg 5, as well as with two symmetrical sides 2 and 3.
Shell l is monolithic and comprises frame elements 6, 7 which are lateral sections between which extend substantially horizontal laths 8 to constitute the seat element, as well as crosspieces 9 joined~by upright laths l0 to form the backrest.
Sides 2 ar;d 3 present the shape of a bow of which the branches constitute a straight front leg ll and a concave rear leg 12 joined together, above the level of the seat element, by a rounded part 13 extended rearwardly by an armrest 14. Of course, sides 2 and 3 may take any other appropriate shape as aesthetically desired, as long as the connection 6~3fi _5_ means recommended hereinafter can be employed.
As shown clearly in Figures 4 to 6, the connection of each shell 1 with a side 2 or 3 is ensured by means of assembly studs 15 and 16 cooperatlng with assembly housings 17 and 18.
The assembly studs 15 and 16 are integral with legs 11 and 12 respectively, being spaced apart there-from and extending upwardly in projection on their inner face. The assembly housings 17 an~ 18 are defined 10 by partitionings of the corresponding frame element 6 or 7 of the shell.
As shown in the example illustrated in Figure 4, the axes 19 and 20 of the housings 17 and 18 are advantageously parallel to direction F of demoulding 15 of the shell, i.e. to the direction in which the two parts of the mould are spaced apart from one another to release said shell from the impression defined by said parts. In this way, the longitudinal partitions 21, 22 and 23, 24 of housings 17 and 18 20 which are in that case substantially parallel (to within the draft of demoulding or the slope of wedging which are mentioned hereinafter) to the direction F, demould easily.
In the example shown, the assembly studs 15 25 and 16 are U-sections whose cross-section may be inscribed in a square for the rear legs 12 and in a rectangle for the front legs 11, which cross-section corresponds substantially to that of the housings 17 and 18.
The longitudinal partitions 21 to 24 are therefore with flat contact parallel to axes 19, 20 and perpendi-cular to the plane defined thereby. A slope slightly greater than the draft of demoulding may be provided on these partitions which consequently, by cooperating 35 with the flanges of the studs 15, 16 in conjugate 2~ 936 slope, cause wedging thereof.
As the sides are relatively large, geometrically deformable moulded parts, the relative positioning of the studs 15 and 16 is not strictly the same for all the sides. Under these conditions, the partitions 21 to 24 are located so that only two of these parti-tions may bear against the flanges of the studs 15 and 16 when these studs are completely fitted in the housings 17 and 18, a slight clearance in that 10 case appearing between the other two partitions and said studs.
The housings are also defined by antero-posterior partitions 25 to 28 extending parallel to the plane defined by axes 19 and 20. They are sloping and spaced 15 apart so that they all bear against studs 15 and 16.
According to a first embodiment (not shown in the drawing), the studs 15 and 16 are moulded with the sides. The mould must in that case comprise mobile 20 parts to allow demoulding.
According to a second embodiment illustrated in Figures 4 to 9, studs 15 and 16 project on moulded parts 29 and 30 respectively. These parts also comprise in projection, in a perpendicular direction, positio-25 ning studs 31 and 32. The latter have a tubular shapeof rectangular section complementary to that of recei-ving housings 33 and 34 respectively defined by the corresponding side 2 or 3. These housings are very easy to obtain, being given that the sides are demoul-30 dable perpendicularly to their lateral faces andthe housings may be demoulded in the same direction, the mould half simply presenting fixed projections at the location thereof.
Studs 15 and 31 are, of course, oriented with 35 respect to one another so that, taking into account _7_ Zl~6 ~3 6 the location of the receiving housing 33 in which the conjugate positioning stud 31 must be fitted, the assembly stud 15 is perfectly aligned with the assembly housing 17. Similarly, the studs 16 and 32 are oriented to take into account the locations of housings 34 and 18.
In order to fix parts 29 and 30 on corresponding' side 2 or 3, screws 35 and 36 pass through holes 37 and 38 made in the bottoms of the positioning 10 studs 31 and 32 and are screwed in holes 39 and 40 in the bo'.toms of housings 33 and 34 of the correspon-ding frame element 6 or 7 of the shell 1. Consequently, parts 29 and 30 are in1_egral with sides 2 and 3, the parts of one side being symmetrical to the parts 15 of the other side, in the same way as the sides are symmetrical with respect to one another. In this way, these sides 2 and 3 present, in projection, suitably oriented assembly studs 15 and 16.
To assemble the piece of furniture (Figures 20 1 to 3), the assembl studs 15 and 16 of each of the sides 1 and 2 are fitted in the assembly housings 17 and 18 of the corresponding frame element 6 or 7 of a shell 1. Screws 41 and 42 then pass through holes 43 and 44 made in the bottoms of the assembly 25 studs 15 and 16 and axe screwed in bushes 45 and 46 of the shell projecting in housings 17 and 18.
In order to improve rigidity of the connection of sides 2 and 3 with the shell 1, the assembly studs 15 ant~ 16 are connected to parts 29 and 30 or to 30 said sides when the latter are moulded with these studs, hy shoulders 47 and 48 (Figures 8 and 9) ensu-ring a wide bearing surface against frame elements 6 and 7 of the shell clnd thus improving the fits.
The same means may be employed for improving the 35 fixation of parts 23 and 30 on sides 2 and 3 and, -8~ 69~
to that end, the positioning studs 31 and 32 are connected to said parts 29 and 30 by shoulders 49 and 50 (Figures 8 and 9) ensuring a wide be.~ring surface against the sides and thus improving fits.
S Considering now the bench illustrated in Figure 2, it is important to recall that the two shells 1 are joined together and supported by an intermediate rear leg 4 and an intermediate front leg 5.
To ensure connection and as shown in Figures 10 10 and 11, assembly housings 17 and 18 of frame element 6 of the right-hand shell in Figure 2 and those of the frame element 7 of the left-hand shell are ~Ised to receive two assembly studs 16 integral with a cap 51 surmounting a leg 4 and, respectively, two assem-bly studs 15 integral with a c;ap 52 surmounting leg 5, fixing screws being positioned as before.
The means described heræinbefore ensure the rigid ~onnection of sides 2 and 3, possibly of inter-mediate legs 4 and 5, with the seat element 8 of shell 1.
The armrests 14 of these sides may also advanta-geously be fixed on the backrest 9, 10 of shell 1.
To that end, various means may be employed, and in particular a system incorporating studs and housings of the type mentioned above.
