  • Such section bar portion 105 is joined with an enlarged end part 107 which is opportunely secured below the horizontal wing 29 of said rectilinear guide section bar 26.
  • the movable elements 32 and 33 are realized with plastic or metallic material and are shaped each one with a square form, defined respectively by an horizontal flat portion 108 and 109 having almost the same length of the portion of section bar 105, for co-operating with it as it will be described, and by a vertical flat portion 109' and 110 bent orthogonally upward from its own horizontal portion and with a size smaller than the size of said horizontal portion, and these vertical portions are bored for allowing the passage of screws, bolts or the like for fixing the same vertical portions, and therefore also the movable elements, to the vertical rear wall of the door 6, in the lower middle position of the same, as visible in the Fig. 7 , in a manner that the horizontal portion of each movable element is projected towards the wardrobe, in a position correspondent to that of the relative portion of section bar 105.
  • each of said horizontal flat portions 108 and 109 there are fixed two pairs of short supports, spaced away to each other in the longitudinal direction of the relative horizontal portion, the first pair of which is formed by the two supports of cylindrical shape 110 and 111 arranged in the front and transversal direction of the relative horizontal portion 108 and 109, which are fixed onto a short vertical edge 112 obtained by bending upward the material of the same horizontal portion, and are aligned and slightly spaced away from each other, thereby defining a short free space, and in the opposite walls of such cylindrical supports 110 and 111 it is pivoted a relative idle wheel 113 and 114, which are identical to each other and have a reduced diameter and a horizontal rotation axis, and these wheels are spaced away to each other of such extent as to be able to engage by sliding into the correspondent side sliding guide member 106 of the relative portion of section bar 105.
  • the second pair of supports is formed by the two cylindrical supports 115 and 116, identical to each other and to the previous supports 110 and 111, which are arranged and fixed in the transversal direction and almost in the central zone of the relative horizontal portion 108 and 109, with the same arrangement and size of said two previous supports, and onto the opposite walls of said cylindrical supports 115 and 116 it is also pivoted a relative idle wheel 117 and 118, which are identical to the previous ones and also spaced away to each other of the same extent, in order to be able to engage by sliding the correspondent side sliding guide member 106.
  • a first and a second sliding wheel 119 and 120 with a vertical rotation axis in positions opposite to each other and turned outwards the horizontal portion, and these wheels are spaced away to each other of such extent as to be able to be arranged on to the flat vertical wing 28 of the rectilinear guide section bar 26, and to be able to slide along the same, when the door 6 is let to slide in the alternate longitudinal direction of the wardrobe.
  • the presence of the above-described stationary and movable elements allows the sliding of each door 6 both in the depth direction of the wardrobe and in the longitudinal direction of the wardrobe, for being displaced from the one to the other one of its opened and closed positions.
  • Figs. 10, 11 and 12 shown therein is the arrangement of the vertical legs for supporting the wardrobe onto the floor, which are opportunely offset to each other to prevent interferences with the horizontal portions 108 and 109 during the sliding of the doors 6 in the wardrobe longitudinal direction.
  • the rear support legs 121, 122, 123 and 124 of the wardrobe are all arranged aligned and opportunely spaced away to each other, whereas the relative front leg 125 and 126 of the wardrobe is arranged in the side position of the same wardrobe, and that the relative intermediate leg 127 and 128 of the wardrobe is arranged in a position misaligned with such front legs 125 and 126, and does not interfere with the longitudinal sliding of the stationary elements 30 and 31 and the movable elements 32 and 33 of each door 6, when this latter is displaced into the opened position thereof. From Fig.
  • the lower stationary and movable elements of the lower component parts 14 of each door 6 are fixed to the relative door in misaligned positions symmetrical to each other, in a manner that when the two doors are overlapped to each other such stationary and movable elements aren't overlapped to each other and, therefore, being not interfering to each other, allow the sliding of the doors without obstacles.
