Abstract
Abstract Metal frame constructed from sections of the same structural element. This structural element is obtained by folding a metal strip to define a substantially square or rectangular cross-section first part (14) and an L-shape cross-section second part (16) and a space is formed between an edge (18) of the metal strip and a fold (19) defining the boundary between said first and second parts so as to define a slot (20) enabling insertion of panel mounting means. Application to the manufacture of metal cabinets for industrial electrical or electronic equipment.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
123 words
Metal cabinet frame at least partly constructed from sections (12) of the same structural element comprising a substantially rectangular cross-section first part (14)and an L-shape cross-section second part (16) joined to said first part so as to define with it a channel (17), wherein sd two parts are defined by parallel folds substantially at right angles in a single metal strip, the edge (18) of one face of said first part is constituted by a longitudinal edge of said metal strip, this edge facing a fold (19) defining the boundary between said first part and said second part, there being a space between said fold and said edge so as to define a longitudinal slot (20) enabling the insertion of panel mounting means.
Claim 2
Dependent Claim
123 words
Metal cabinet frame at least partly constructed from sections (12) of the same structural element comprising a substantially rectangular cross-section first part (14)and an L-shape cross-section second part (16) joined to said first part so as to define with it a channel (17), wherein sd two parts are defined by parallel folds substantially at right angles in a single metal strip, the edge (18) of one face of said first part is constituted by a longitudinal edge of said metal strip, this edge facing a fold (19) defining the boundary between said first part and said second part, there being a space between said fold and said edge so as to define a longitudinal slot (20) enabling the insertion of panel mounting means.

Claim 4
Dependent Claim
28 words
Metal frame according to claim 1, wherein at least one outside face (14c) of said first part of a section constitutes a bearing surface for a seal (25).
Claim 5
Dependent Claim
28 words
Metal frame according to claim 1, wherein at least one face (16a) of said second part (16) of a section constitutes a bearing surface for a seal (25).
Claim 6
Dependent Claim
25 words
Metal frame according to claim 1, wherein one face of said second part is provided on its inside with a row of blind holes (45).
Claim 7
Dependent Claim
27 words
Metal frame according to claim 5, wherein said blind holes are through-boles in a marginal area (46) of said metal strip which is folded on itself longitudinally.
Claim 8
Dependent Claim
52 words
Metal frame according to claim 1, wherein said fold (19) defining the boundary between said first and second parts defines a longitudinal groove (48) along one side of the corresponding face (14d) of said first part so as to form outside the fold a rounded edge (48a) of said longitudinal slot (20).
Claim 9
Dependent Claim
39 words
Metal frame according to claim 7, which further comprises fixing blocks (50) housed in the aforementioned channels (12) of some sections, a fixing block comprising at least one screwthreaded hole (51) adapted to receive a panel fixing screw (52).
Claim 10
Dependent Claim
38 words
Metal frame according to claim 7, which further comprises fixing blocks (50) housed in the aforementioned channels (12) of some sections, said fixing blocks each comprising at least one bore (54) adapted to receive a door pivot pin.
Claim 11
Dependent Claim
120 words
Metal frame according to claim 7, wherein one face of said second part is provided on its inside with a row of blind holes (45), further comprising a fixing block having an engagement face 965) adapted to bear against a face of said channel and provided with at least one peg (66) adapted to be inserted into a said blind hole, bearing faces (67, 68) oriented to bear against the other faces of said channel and an oblique wing (70) through which is formed at least one screwthreaded hole (72) receiving a screw (73), said hole being positioned and oriented so that said screw can enter said longitudinal groove (48) in order to immobilize the fixing block in said channel.
Claim 12
Dependent Claim
