The upright bars (3, 4) and the lower bars (1, 2) are joined by means of a folding unit (5, 6), comprising an upper house (11) fixed to an upright bar (3, 4) and a lower base (10) fixed to a lower horizontal bar (1, 2). The upper house (11) and lower base (10) comprises mating rear locking means (17a, b), mating front locking means (16a, b), and a horizontal rotation axle (12) attached to both the upper house (11) and the lower base (10), around which the upper house (11) rotates relative to the lower base (10). The upper house (11) further comprises two lateral sides and a front side providing support for the upright bar (3, 4) in a locked position and a rear side being open to allow for rearward folding of the upright bar.
