The leg supports (2) are for a dismantlable frame (1) and work in conjunction with a holder (5) extending at an angle towards two legs (3,4) adn involving an upper flange joined to a side piece. This ensures the non-twistable connection between the frame beam and the leg supports. The two legs are pivotable relatively to one another in that they are mutually connected via a joint (6) under the holder (5). From the joint extend long lower sections of the legs downwards and short upper sections extend upwards to serve as clamp jaws to secure the beam firmly when the leg lower sections are folded away from each other. The side piece and the corresponding flange are rigidly joined to the upper sections of the first leg (3). |
