  • the devices 1 and la are mounted or mountable to the top 7 of the wardrobe 3 and therefore are particularly disposed as a mirror-image of each other with respect to a symmetry plane of the wardrobe 3 itself, such symmetry plane particularly coinciding with the mid vertical plane of the wardrobe 3, disposed substantially normal to the doors 2 and 2a.

  • the devices 1 and la share the same guide or track 6 and, additionally, that such shared guide or track 6 is symmetric with respect to the midplane of the wardrobe 3. Therefore, such shared guide or track 6 is formed by a pair of first portions 6' connected to each other by the second portion 6", the first portions 6' being advantageously a mirror-image of each other with respect to the midplane of the wardrobe 3.
  • the guide or track 6 is made by a single profile (for example of metal material or plastic material) suitably shaped or by a plurality of profiles disposed one following the other: for example, the guide or track 6 can be obtained by arranging adjacently to each other a first profile suitable for forming the first portion 6' and a second profile suitable for forming the second portion 6".

Therefore, the intermediate portion 18 of the bracket 15 is disposed between the connecting flanges, the main purpose of said bracket 15 being holding the door 2 at a predetermined distance from the bar 4. It is important to size the intermediate portion 18 for preventing it from restricting the door 2 stroke. For example, it is important that the intermediate portion 18, when is substantially coplanar or parallel to the flange connecting the bracket 15 to the bar 4, has a depth suitably greater than the thickness of the door 2
  • the intermediate portion 18 has a width less than half the width of the door 2 (and therefore than the width of the door 2a) in order to not abut against the associated bracket of the other door 2a
  • the intermediate portion 18 is at a level greater than the maximum level reached by the door 2 (and therefore than the maximum level reached by the door 2, under the assumption the two doors 2 and 2a are installed substantially at the same height, besides of substantially having the same size), so that the door 2, during its opening movement, it does interfere with the other door 2a.
  • the movement device 1, is capable of causing the door 2 to take at least one closed position and an open position (represented in Figure 2 and in Figure 4, respectively) . Since the doors 2 and 2a are juxtaposed to each other, when the wardrobe 3 is closed, the door 2 requires to follow, during the initial opening step thereof, a trajectory such to prevent impacts against the other door 2a, wherein the displacement of the door 2 towards the opening occurs after, or is combined with, the detachment of the door 2 from the wardrobe 3.
  • the trajectory of the door 2 during its final closing step reproduces the trajectory followed by the door 2 during its initial opening step, in order to always prevent impacts against the door 2a.
