Definitions

• the present invention refers to a support and actuation arrangement for the sliding doors of wardrobes and similar cabinets having doors of a kind capable of sliding in an alternate longitudinal direction along upper and lower rectilinear rails, that are applied to run along the ceiling and the bottom of the related cabinet, respectively, wherein such doors are capable of being actuated at the same time to symmetrically slide, i.e. following symmetrical sliding directions, from the opened position to the closed position thereof, and vice-versa.
• the doors move from a closed position, in which they lie in a slightly recessed condition in the depth direction of the cabinet, to an opened position, in which they are first caused to- move forwards for a short length of travel and are then caused to slide sideways into the desired position, in a direction parallel to the plane of the front face of the cabinet, along rectilinear rails running parallel to each other as applied onto the ; bottom and the ceiling of the cabinet, respectively.
• the arrangements provided to support and actuate such doors are designed so as to ensure that the right side of the doors will in all cases move jointly with the left ,side of the same doors, and that such synchronism of movement is also true as far as the upper side and the lower side of such doors relative to each other is concerned.

• the door 6 is displaced at both the lower portion thereof, by means of the lower transverse profile section 51 and the lower cylindrical roller 90, and the upper portion thereof, by means of the upper transverse profile section 36 and the upper cylindrical roller 82, with a synchronized movement.
• Figure 23 solely illustrates the upper rotating pulley 86 of the upper cylindrical roller 82, in the race 96 of which there are wound several turns of a flexible steel cord 97 forming the motion transmission system to and from the upper transverse profile section 36 and the lower transverse profile section 51 , said flexible steel cord being also wound in the same manner round the other pulley 94 of the lower cylindrical roller 90.
• Shown in Figure 24 is the motion transmission system used as a motion transmission means to and from said upper and lower transverse profile sections, in a second embodiment thereof.
• the motion transmission system is comprised of a cog belt 98 wound round a corresponding rotating cog-pulley 99 co-axially coupled to the upper cylindrical roller 82, and such cog belt is also wound round the other rotating cog-pulley (not shown) that is co-axially coupled to the lower cylindrical roller 90.
• Shown in Figure 25 is the motion transmission system used as a motion transmission means to and from said upper and lower transverse profile sections, in a third embodiment thereof, wherein such motion transmission system is in this case comprised of a metal perforated strap 100 wound round a corresponding rotating cog-pulley 101 co-axially coupled to the upper cylindrical roller 82, and such perforated strap is also wound round the other rotating cog-pulley (not shown) that is co-axially coupled to the lower cylindrical roller 90.
• a metal perforated strap 100 wound round a corresponding rotating cog-pulley 101 co-axially coupled to the upper cylindrical roller 82, and such perforated strap is also wound round the other rotating cog-pulley (not shown) that is co-axially coupled to the lower cylindrical roller 90.
• FIG. 26 to 31 A further embodiment of the motion transmission system used as a motion transmission means to and from said upper and lower transverse profile sections is shown in Figures 26 to 31 , wherein such motion transmission system is in this case comprised again of a flexible steel cord 97, which is wound round the races 102 of two upper horizontal-axis pulleys 103 similar to each other and firmly joined with each other in a coaxial arrangement relative to each other, which are rotatably hinged on to the upper end portion of the vertical profile section 28 of each cabinet (see Figures 27 and 28), and said flexible steel cord is also wound round the race 104 of a vertical-axis deviation pulley 105 that is rotatably hinged on to a support bracket 106 attached to said upper end portion of the vertical profile section 28 and a securing bolt 107 that is inserted transversally in the profile section 36.
• a flexible steel cord 97 which is wound round the races 102 of two upper horizontal-axis pulleys 103 similar to each other and firmly joined with each other
• the steel cord 97 is also wound round the races 108 of two lower horizontal-axis pulleys 109 similar to each other and firmly joined with each other in a coaxial arrangement relative to each other, which are rotatably hinged on to the lower end portion of the vertical profile section 28 (see Figure 29), and also in this case said flexible steel cord is wound round the race 110 of a vertical-axis deviation pulley 111 that is rotatably hinged on to a support bracket 112 attached to said lower end portion of the vertical profile section 28, and the securing bolt 107 is inserted transversally in the transverse profile section 51.
• Figures 30 and 31 illustrate this motion transmission system using such flexible steel cord 97, as installed on the upper portion of the wardrobe cabinet.
• the flexible steel cord 97 is deviated round the two upper horizontal-axis pulleys 103 and the vertical-axis deviation pulley (not to be seen in the Figures) rotatably hinged on to the bracket 106, and is secured with the related bolt 107 in the transverse direction of the upper profile section 36. so that this profile section 36 can still be displaced, in the afore-described manner, from the closed position of the door 6 in Figure 30 to the opened position of the same door in Figure 31 , and vice-versa.
• the motion transmission system used as a motion transmission means to and from said upper and lower transverse profile sections 36, 51 may also be embodied using any other motion transmission member or means as- largely known as such in the art and differing from the ones that have been described above by mere way of illustrative example, without this meaning any departure from the scope of the present invention.
• FIG. 34 Illustrated in greater detail in Figure 34 are the two different construction members making up the structure of the metal profile section 16 that forms the first component part of the inventive door support and actuation arrangement, which has been already described hereinbefore with reference to Figures 5 and 6 and, for the matter, substantially comprised of both said profile section 16, as shaped in the afore-described manner and attached to the upper portion of the door 6, and a rectilinear vertical profile section 19 secured to said profile section 16 and provided with a lower groove 20 for the door to slide therein, as well as an angle section 21 attached to the ceiling 10 of the cabinet.
• the profile section 16 is provided with a sequence of through-apertures 114 regularly spaced from each other over the entire length of the same profile section, the purpose of which consists in enabling the front wheels 45 rotatably hinged on to the angle section 21 to be received and accommodated there in the closed condition of the door (see Figure 38), as well as enabling also the front wheels 32 of the upper skid 29 to be received and accommodated there in the opened condition of the door (see Figures 39 to 41), in which said wheels 32 move into an arrangement in which they are longitudinally aligned with the wheels 45.
• the rectilinear vertical profile section 19 is so shaped all along the longitudinal extension thereof as to include an upper recess 115 that is fitted into the rectilinear bent border 116 of the profile section 16, thereby securing these profile sections to each other, and is further so shaped as to include the afore- described lower slit or groove 20, as well as a sequence of semi-circular recesses 117 provided all along a front face of the same profile section and regularly spaced from each other with a centre-to-centre distance between them that is equal to the one between the wheels 45, so as to be able to fit onto the corresponding front wheels 45 of the profile 16 in the closed position of the door 6.
• FIGs 32 to 37 illustrated in Figures 32 to 37 is the lower portion of the door 6 and the manner in which it is shifted from its closed position (see Figure 33), on the front side of the wardrobe cabinet, and into its opened position (see Figure 32).
• the angle section 24 which is secured to the lower portion of the door 6 by means of brackets 26, engages with the vertical portion 27 thereof the slits 60 in the shoes 54 and 55, which are secured to the angle section 47, to thereby be firmly retained there without being able to displace.
• the middle roller 58 of each skid lies aligned with and spaced from the projecting lug 75 and the slanting wall 76 of the respective movable front plate 72 of the vertical shoes 69 and 70, which are applied against the angle section 61 attached to the lower skid 46, and such movable plate 72 is kept in its lowered resting position by the spring 78.
• the assembly comprised of the shoes 54 and 55 and the middle roller 58 is at the same time displaced forwards gradually by the action of the angle section 24 engaging the same shoes, whereas the angle section 61 and the movable front plate assembly 72 keep at rest, i.e.
• the middle roller 58 moves gradually closer to the projecting lug 75 and the related slanting wall 76 and, as soon as it comes to abut against the slanting wall 76, it starts sliding thereupon, so that, as the roller 58 keeps in this way sliding forwards, it causes the projecting lug 75 to gradually rise jointly with the related movable plate 72, which in turn causes the spring 78 to become gradually compressed, thereby clearing the rectilinear sliding path of the brackets 26 and the angle section 24.
• each door 6 being actuated into closing or opening occurs in this case with different ' movements that are no longer synchronized with each other.
• the door can be actuated into opening by first pulling its handle outwardly so as to first of all displace a side of the door, i.e. the lower side in the example being described (see Figure 43), until the related abutment is reached and the door is now inclined frontwards, and then pulling the remaining side of the door, i.e.
