The load carrier has frames of strip material which are folded transverse the longitudinal direction of the strip along lines in the plane of the strip. Each frame has an elongate web surface and two legs joined to the webs by folding the strip at right angles. Each frame (1,2) has two webs which, by folding the strip at right angles and towards each other, are each connected to a leg (12,13,22,23). A web (24,25) on one frame is inserted in the second frame so that this web and a second web (14,15) overlap near the legs. |
