Assembly railed formed out of at least one profile element

An assembly rail (1) comprising:

• at least one U-shaped profile element (2, 2*, 12) having a base and two parallel legs connected to the opposed ends of the base, wherein the two parallel legs each have an upper end distal from the base, respectively, wherein the upper ends are bent inwardly toward an interior of the at least one profile element (2, 2*, 12) and form support legs (4, 4′;
• 14, 14′) having free ends spaced closer together than the two parallel legs;
• a rail slot (3, 13) defined between the free ends of the support legs (4, 4′;
• 14, 14′) and extending in a longitudinal direction of the at least one profile element (2, 2*, 12);
• a hollow profile (10, 20) larger than the at least one profile element (2, 2*, 12) and having edge strips (5, 5′, 15, 15′;
• 47, 47′) arranged along at least one longitudinal side of the hollow profile (10, 20), wherein the edge strips have end faces facing one another and forming therebetween a receiving slot (6,16);
• wherein the at least one profile element (2, 2* 12) has a width measured perpendicularly to the two parallel legs matching a width of the receiving slot (6, 16) and is arranged in the receiving slot (6, 16), wherein an exterior side of the two parallel legs is connected fixedly to the end faces of the edge strips (5, 5′, 15, 15′;
• 47, 47′) of the hollow profile (10, 20);
• and
• wherein the rail slot (3, 13) of the at least one profile element (2, 2*, 12) opens outwardly.
