Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
202 words
In a partition, a longitudinal beam having a substantially Ushaped cross-section and comprising a transverse wall, two outer side walls and two inner side walls, each of said inner side walls being located close to a separate outer side wall, the distances of the inner side walls from their adjacent outer side walls being the same, each of said inner side walls being substantially L-shaped in cross-section and having a limb extending parallel to the adjacent outer side wall and a limb extending parallel to said transverse wall and away from the adjacent outer side wall, ribs carried by said transverse wall and forming two parallel channels and ribs carried by said outer side walls and forming two parallel channels, each of said channels having a substantially U-shaped cross-section, the two first-mentioned channels extending along opposed lateral edges of said transverse wall, the two second-mentioned channels extending along lateral edges of said outer side walls, said channels having openings directed towards the outside of said beam, ribs carried by said outer side walls being located between the outer side walls, and ribs carried by said transverse wall being located on the side of said transverse wall opposed to the outer side walls.
Claim 2
Dependent Claim
202 words
In a partition, a longitudinal beam having a substantially Ushaped cross-section and comprising a transverse wall, two outer side walls and two inner side walls, each of said inner side walls being located close to a separate outer side wall, the distances of the inner side walls from their adjacent outer side walls being the same, each of said inner side walls being substantially L-shaped in cross-section and having a limb extending parallel to the adjacent outer side wall and a limb extending parallel to said transverse wall and away from the adjacent outer side wall, ribs carried by said transverse wall and forming two parallel channels and ribs carried by said outer side walls and forming two parallel channels, each of said channels having a substantially U-shaped cross-section, the two first-mentioned channels extending along opposed lateral edges of said transverse wall, the two second-mentioned channels extending along lateral edges of said outer side walls, said channels having openings directed towards the outside of said beam, ribs carried by said outer side walls being located between the outer side walls, and ribs carried by said transverse wall being located on the side of said transverse wall opposed to the outer side walls.
Claim 3
Dependent Claim
22 words
A longitudinal beam in accordance with claim 1, wherein said ribs have chamfered edges to increase the width of the channel openings.
Claim 4
Dependent Claim
66 words
In combination with the longitudinal beam of claim 1, a partition wall, a bracket connected to said wall and extending into the space between said two inner side walls, and two L-shaped framing elements, each of said L-shaped framing elements having a limb extending into a separate one of the first-mentioned channels and another limb extending parallel to said wall and engaging a lateral surface thereof.
Claim 5
Dependent Claim
61 words
In combination with the longitudinal beam of claim 1, two L-shaped framing elements, each of said L-shaped framing elements having a limb extending into a separate one of the first-mentioned channels and another limb, a U-shaped member having side legs engaging the second-mentioned channels, and a glazed wall extending between the other limbs of said framing elements and said side walls.
