DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION




In the embodiment shown in

FIG. 1

, the modular structure according to the invention has been used to provide a piece of furniture


1


formed by a composition of cabinets and shelvings composed by the base member


2


defining a shelf


22


, a base


20


and a cover


21


, supported by uprights


3


.




Preferably, all the component parts of the illustrated structure are made of plastics even though the use of other materials is not precluded.




As shown in

FIGS. 2 and 3

, the intermediate shelves


22


, the bottoms


20


and the covers


21


are constituted by the same modular member


2


having a substantially rectangular shape and provided with twin holes, respectively


5


-


6


,


7


-


8


,


9


-


10


,


11


-


12


, at its corners. The lower ends


13


and


14


of uprights


3


are inserted inside the twin holes and are constituted by pillars


15


and


16


which are joined by rigid cross links


17


in order to be parallel and spaced apart by a distance equal to the distance between each twin hole. The same pillars are provided with upper ends


18


,


19


inserted in corresponding holes in the upper shelf.




The uprights are assembled by inserting the ends inside the shelf twin holes


5


-


6


,


7


-


8


,


9


-


10


,


11


-


12


.




According to an important feature of the present invention, the pillars


15


,


16


and twin holes


5


-


12


on the modular members


2


allow to rapidly and stably superimpose and/or lay side by side different shelf members


20


,


21


,


22


as shown in

FIGS. 2 and 3

.




To this end, the modular members


2


may be coupled, on the horizontal plane, by inserting the uprights


3


across the connecting lines between the same members


2


. In this case, the pillar


15


of an upright is inserted in the outermost hole of the twin holes of a first modular member


2


, while the pillar


16


of the same upright is inserted in the outermost hole of the corresponding twin holes of the adjacent modular member. In this case, for example, the lower ends


13


,


14


of an upright


3


are inserted in holes


11


,


5


respectively, of two adjacent modular members


20


, while the upper ends


18


,


19


of the same upright


3


are inserted in the corresponding holes


11


,


5


of the upper shelves


22


(FIG.


3


)




A mutual connecting bridge is thus provided, on the horizontal plane, between adjacent modular members


2


, by using to this end the same uprights


3


that serve for expanding the piece of furniture


1


vertically.




In order to provide greater stability to the piece of furniture, the above described twin holes in the corners of the modular members


2


also allow the insertion of two pillars


3


at a same corner on the mutual connection section between two adjacent members


2


(FIG.


3


). In this manner, each modular member is anchored at eight points and is therefore extremely stable and adapted to carry a considerable weight.




The two shorter sides of the modular members


2


are laterally closed by a stiffening profile


23


which is slidingly inserted inside the members


2


and is provided with holes in the same position of the holes


5


-


12


described above. Caps


24


are provided for closing the holes that are not used for the connections between the modular members


2


. The ends of the uprights


3


are provided with a circular shoulder


25


which, once the structure is assembled, rests on the surface of the members


2


which is arranged around the holes


5


-


12


.




The modular members


2


, together with the side members


23


used for providing the above described shelving, may be used for constructing cabinets


4


of

FIGS. 1 and 4

. In this case, the mutual connection, on the horizontal plane, between adjacent modular members


2


, is provided by means of twin pins


26


having a construction similar to the above described construction of the uprights


3


with the difference that the pins are considerably shorter.




For the above reason, the twin pins


26


allow to expand the structure horizontally, according to a system similar to the system described above for the uprights


3


. These pins


26


are in fact arranged with their ends across adjacent modular members


2


and inserted in respective holes at the corners.




The vertical expansion of the cabinet


4


which is based on said pins


26


is instead achieved by means of wings


27


,


28


and


33


of the cabinet. More particularly, adjacent rear wings


28


are joined together and fastened to respective bottom modular member


20


and cover modular member


21


, at their junction line, by means of a twin pin


26


inserted on one hand into holes


29


,


30


provided on the corresponding longitudinal side of the same modular member


20


and


21


, and, on the other hand, in respective holes (not illustrated) provided at the ends of the same wings.




The ā€œLā€ shaped mutual connection between the rear fixed wings


28


and the respective side fixed wing


27


is provided by engaging a peg


31


of the twin pin


26


into the rear wing and the remaining peg


32


into the side wing. The other end of these pegs is instead arranged into holes


5


,


6


and


11


,


12


of the modular members


2


, in the manner already described with reference to

FIGS. 1 and 3

.




The side wing


27


is fastened to the member


2


also by a single pin


37


arranged, on one hand, in the hole provided on the remaining end of wing


27


and, on the other hand, into the innermost hole


7


,


10


of the respective modular member


2


.




The twin pins


26


and the single pin


37


are also provided with peripheral annular shoulder


38


having the same height of ridges


39


that function for centering the position of the fixed wings on the modular member


2


.




The mobile wings


33


are provided with closure end caps


34


that are in turn provided, on the inner side, with pegs


35


insertable in the wing. A pin


36


is provided on the outer side of caps


34


, i.e. on the side opposite to that of pegs


35


. Pin


36


is arranged in the respective outer hole


8


,


9


of modular member


20


or


21


of the cabinet thus defining a hinge for the wing acting as a door.




The pegs


35


are further locked in this wing by an elastic tang


40


projecting from their side surface and snapping inside a slot


41


formed in the wing. The wing caps


34


are also provided with hollow cylinders


42


adapted to lock on the body of the wing at corresponding cylindrical seats


43


.




A projecting tang


44


is provided on the ends of caps


34


opposite to the ends provided with the outer pegs


34


. The projecting tang


44


is adapted to snap on the closure of wing


33


in corresponding seats


45


provided on the sides of the modular members


20


and


21


where the wing closes.




Racks


46


are also provided for supporting shelves


47


of the cabinet


4


. In the embodiment shown in

FIG. 5

, pins


26


and


37


are made integral with a connecting strip


48


provided with cylinders


49


and functioning in a manner similar to that of cap


34


described above.




As shown in

FIG. 1

, the shelves of FIG.


3


and the cabinets of

FIG. 4

may be combined together to form a composition wherein the modular members


2


form the intermediate shelves


22


as well as the bottom


20


and the cover


21


of both the cabinets and of the shelving. In this embodiment, the combined engagement of the uprights


3


and of the single and twin pins


26


,


37


inside holes


5


-


12


of the modular elements


2


allow to superimpose and/or to lay side by side several cabinets


4


and shelving


22


thus obtaining a composite structure as the one shown in FIG.


1


.




The above described composite structure allows to expand the shelving both horizontally and vertically, also at different times, and by using modular components that make the assembling easy and reduce the overall production costs.




The modular structure according to the invention may be modified within the scope of the following claims. In fact, as said above, the materials may be different from plastics. Also the shape of modular members may be different from the shape illustrated and the structure mutual connecting means may be substituted with functionally equivalent connecting means.
