Modular member for forming composite false-ceilings

Claim 2

A module for forming composite false-ceilings comprising a grid formed by walls extending transversely to each others in a first and in a second direction, said grid forming walls having end portions forming outer sides of said grid; at least, two side walls connected to end portion of said grid forming walls, said grid forming walls and side walls having an equal height defining a module height; matching engagement means provided at said outer sides of said grid and extending towards exterior of said grid, said matching engagement means consisting of male elements and female elements provided on different outer sides of said grid, each said male element comprising a substantially conical pin extending throughout said module height and having, at a larger base thereof, a head extending substantially perpendicularly to said conical pin, said head presenting a face looking towards said conical pin and supporting at said face at least one snap means, each female element comprising a substantially cylindrical body having smaller height than said module height thereby defining a free portion, said substantially cylindrical body presenting a hole therein and a longitudinal slot extending throughout said cylindrical body height, said free portion of said wall having at least one port cooperating with said at least one snap element of adjacent modules thereby causing a snap engagement of said snap element with said port and therefore a snap engagement of adjacent modules with each other.

Claim 3

A module according to claim 1, wherein said male elements are provided on and integral with said end portion of said grid forming walls and said female elements are provided on said side walls at connection points thereof with said grid forming walls.

Claim 4

A module according to claim 1, wherein at least one of said side walls extends parallel to said first direction.

Claim 5

A module according to claim 1, wherein one side wall extends parallel to said first direction and the other side walls extend parallel to said second direction and said grid has a substantially rectangular shape.

Claim 6

A module according to claim 1, wherein said first direction and second direction are perpendicular to each other.

Claim 7

A module according to claim 1, comprising a pair of snap means, arranged at two different sides of said pin, each snap means having a lug departing from said head in a direction substantially parallel to said pin and presenting, at an end opposite to said head, an outwardly projecting tooth for engaging in said at least one port.

Claim 8

A module according to claim 1, wherein said hole presents a quadrangular cross-section, a corner whereof being defined by said slot.

Claim 9

A module according to claim 1, wherein said at least one port is defined by a recess in said side wall at said free portion and by a cross-piece extending transversely in said recess.

Claim 10

A module for forming composite false-ceiling comprising a substantially rectangular grid formed by walls extending perpendicularly to each other in a first and in a second wall extending direction, the grid forming walls having end portions forming outer sides of said rectangular grid, at least two side walls defining two first adjacent outer sides of said grid and being connected with first end portions of said walls forming said first adjacent outer sides, said grid forming walls and side walls having a height defining a module height, matching engagement means consisting of male elements and female elements extending outwardly to said grid, said male elements being integral with second end portions of said grid forming walls defining two second adjacent outer sides of said grid each opposite to a respective of said two first adjacent outer sides, said male elements comprising a substantially conical pin extending throughout said module height and having, at a larger base thereof, a head member extending substantially perpendicularly to said conical pin but substantially parallel to a respective of the second two adjacent outer sides of the grid, said head having a face looking towards said conical pin and supporting at said face two snap means arranged at two opposite sides of said pin and having each a lug departing form said head in a direction substantially parallel to said pin, said lugs presenting each, at an end opposite to said head, a tooth outwardly projecting with respect to said grid for engaging with female elements of adjacent modules, said female elements being arranged on said side walls at connection points thereof with said first end portions, each female element comprising a substantially cylindrical body having a smaller height than said side wall height thereby defining a free portion of said side wall height, said side walls presenting a recess at said free portion defining, together with a cross-piece extending transversely to said recess, an engaging port for said teeth of said snap elements, each said port being divided in two parts by a respective first end portion of said grid forming walls, said substantially cylindrical body presenting a hole therein with quadrangular cross-section and a longitudinal slot extending throughout said cylindrical body height and defining a corner of said quadrangular hole thereby allowing the introduction of said pin in said hole and an elastic deformation of said cylindrical body as well as the snap engagement of said teeth in said ports and therefore of adjacent modules with each other.

Claim 11

A module for forming composite false-ceiling comprising a substantially rectangular grid formed by walls extending perpendicularly to each other in a first and in a second wall extending direction, the grid forming walls having end portions forming outer sides of said rectangular grid, at least two side walls defining two first adjacent outer sides of said grid and being connected with first end portions of said walls forming said first adjacent outer sides, said grid forming walls and side walls having a height defining a module height, matching engagement means consisting of male elements and female elements extending outwardly to said grid, said male elements being integral with second end portions of said grid forming walls defining two second adjacent outer sides of said grid each opposite to a respective of said two first adjacent outer sides, said male elements comprising a substantially conical pin extending throughout said module height and having, at a larger base thereof, a head member extending substantially perpendicularly to said conical pin but substantially parallel to a respective of the second two adjacent outer sides of the grid, said head having a face looking towards said conical pin and supporting at said face two snap means arranged at two opposite sides of said pin and having each a lug departing form said head in a direction substantially parallel to said pin, said lugs presenting each, at an end opposite to said head, a tooth outwardly projecting with respect to said grid for engaging with female elements of adjacent modules, said female elements being arranged on said side walls at connection points thereof with said first end portions, each female element comprising a substantially cylindrical body having a smaller height than said side wall height thereby defining a free portion of said side wall height, said side walls presenting a recess at said free portion defining, together with a cross-piece extending transversely to said recess, an engaging port for said teeth of said snap elements, each said port being divided in two parts by a respective first end portion of said grid forming walls, said substantially cylindrical body presenting a hole therein with quadrangular cross-section and a longitudinal slot extending throughout said cylindrical body height and defining a corner of said quadrangular hole thereby allowing the introduction of said pin in said hole and an elastic deformation of said cylindrical body as well as the snap engagement of said teeth in said ports and therefore of adjacent modules with each other.
