Abstract

Abstract Modular furniture is disclosed which is made up by linking together a series of hollow, internally ribbed panel elements, which are adapted to function as walls and partitions and shelves, through elongated, rectangular joint members which are interposed between the adjacent edges of each pair of panel members; each joint member being provided with a set of fingers and fins projecting from each of its faces that borders on edge of a panel member so that such fingers and fins project, respectively, into sockets and slots formed by the internal ribbing and walls of that panel member and hold it in position. Each finger is preferably formed with two elastic prongs whose facing sides slope toward each other so that they can be spread apart by a wedge member associated with the socket in the panel which that finger enters, to force those prongs against the walls of that socket.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 86 words
Modular furniture structure comprising elements moulded in plastic slotted in to each other, including flat sections 1 linked together by means of joints 2, each of the flat sections being hollow and having two series of three internal ribs 3, each series forming two sockets or slots 4 and two intermediate internal ribs 5 which in their turn form two sockets or slots 6 and two grooves or notches running lengthwise on the upper and lower surfaces of the section itself located towards the rear side.
Claim 2
Dependent Claim 86 words
Modular furniture structure comprising elements moulded in plastic slotted in to each other, including flat sections 1 linked together by means of joints 2, each of the flat sections being hollow and having two series of three internal ribs 3, each series forming two sockets or slots 4 and two intermediate internal ribs 5 which in their turn form two sockets or slots 6 and two grooves or notches running lengthwise on the upper and lower surfaces of the section itself located towards the rear side.
Claim 3
Dependent Claim 75 words
Modular furniture structure conforming with claim 1 in which each of the joints is made up of square-shaped bar 10 on each side of which are located two pairs of elastic vanes 11 extending normally to the axis of the bar and sections of vanes running lengthwise and parallel to each other 12 projecting sideways and forming the relative ends 13 of the slots where the intermediate ribs 5 of the flat section are housed.
Claim 4
Dependent Claim 48 words
Modular furniture structure conforming to claim 2 in which the joint element presents a notch or groove 14 running around the entire perimeter of the element, located towards the end of the bar, and which corresponds to the groove which is to be found on the flat section.
Claim 5
Dependent Claim 58 words
Modular furniture structure conforming to claim 2 in which the elastic vanes 11 of the joint element 2 are elastically coordinated to the slots 4 of the flat section while the parallel vanes running lengthwise 12 are in their turn matched to the slots or sockets 6 formed by the internal intermediate ribs of the said flat section.
