More in particular, this invention relates to a guide as defined above in which the blocking member to prevent disunity of said door from said sliding rail can be easily inserted and removed from the sliding rail seat without using any tool at all and also constantly remains in the most appropriate position in said rail seat regardless of the height adjustment of the door wardrobe.

The furniture provided with sliding doors It is currently more widespread and more appreciated, as it allows the obstructions due to the projection of the own ones are eliminated doors in the opening stage, also from the point of view aesthetically, furniture with sliding doors has an advantage appreciable due to the lack of hinges that could remain at less partly visible and alter the linearity of one's own furniture.

Generally specific mechanisms are used to get the sliding of furniture doors, which consist in small cars comprising wheels, sliding blocks, bearings or the like; the cars are contracted to the doors by the upper edge thereof and, through said rolling means, they slide down the rails or seats formed in bars of metal section with appropriate shape. The section bars are secured to the frame carrying the furniture, in the vicinity from the front side of it both at the top and in the bottom and generally comprise two sliding seats paired for so many doors or groups of doors, internal and external In the assembly stage, the doors alone are provided with car hooks first to the top lane where they remain hung but with the possibility of oscillating; immediately after, the mechanism located on the lower side of the door is brought to insert into the corresponding seat, moving so appropriate the door itself.

The coupling of the internal doors and external with the device of the respective cars along the seats of the metal section bars arranged in the upper part is not particularly difficult; on the contrary, the subsequent hooking of a locking member to prevent disunity of said door of said slide rail is very difficult due to the position of the cars themselves near the roof, no allows visual checks to the operator and often causes a imprecise operation. Under these conditions, handle the tools needed to lock the blocking member to prevent disengagement of said door from said slide rail is more difficult. If the latter is not arranged in a way appropriate in the car, the risk that the door can be unhooking and damaging the furniture is real; Taking into account that the doors often have a considerable weight, the disunity accidental of them can cause serious damage to people. He blocking member to prevent disunity of said door from said sliding rail is difficult to apply on the car in the door assembly stage and sometimes it is even more difficult to remove in case of removal of the door itself.

In addition, the non-secondary inconvenience related to the fact that the blocking member to prevent disunity of said door from said Sliding rail ensures the door carriage and that this last one often needs height adjustments, for that purpose, the car, which is provided with adjustment slots in relation to the door, it works, but in many cases altering the correct position of the blocking member to prevent disunity of said door from said sliding rail

An up or down movement of the car necessarily also involves the locking member for prevent disengagement of said door from said slide rail, whose effects could therefore be canceled, risking the door stability

US2001010426 and DE202005007687 describe support and sliding systems for doors furniture they need, after mounting the door, a operator intervention with your hand or with a tool to insert the block member (s) to avoid disunity from the upper side of the door.

The object of this invention is to bypass the inconveniences cited above.

More in particular, the object of this invention is to provide a device for sliding closet door in which the upper carriage of the doors themselves, which integrates the block member (s) to prevent disunity of said door of said slide rail, it can be engaged or disengaged in a substantially automatic way, without the help of tools, of the respective sliding rail.

Another and non-secondary object of the invention is provide a device for sliding closet door as defined above in which the position of the blocking member (s) to prevent disunity of said door of said slide rail is not influenced by the vertical movement of the upper door carriage, carried out to adjust the height of the door itself.

Last but not least, an object of the invention is to provide a sliding door device of cabinet in which the locking member to prevent disunity of said door of said slide rail associated with the carriage Upper doors are automatically placed without the need for tools in the seat created in the secured section bar to the support frame.

Another object of the invention is to provide the users of a sliding cabinet door device appropriate to ensure a high level of resistance and reliability durable, also in such a way that it is built easily and cheap.

These and even other objects are achieved by a device for sliding closet door according to claim 1. Other advantageous aspects of the invention are described in the subordinate claims.

Referring to Figures 1, 2 and 3, a device for sliding closet door according to this invention comprises a carriage, indicated globally with 10 in Figure 1 and intended for internal and external doors, composed of a profiled frame 12 having a substantially inverted "U" shaped section, in which the opposite and parallel rear 14 and front 16 walls have different heights. In particular, the rear wall 14 of the frame 12 is intended to be secured to the cabinet door (not shown) by conventional screws and therefore is provided with multiple through holes 18. The distance between said walls 14 and 16 is approximately between 15 and 40 mm and defines, in the central-upper part of the frame 12, a cavity with a rectangular profile and extending longitudinally, in which a support 20 for a rolling member 22, provided with a central passage hole 22 'is provided and for a locking member to prevent disengagement of said door from said slide rail 24. The support 20 defines an inverted "U" shaped profile in which the opposite and parallel front and rear walls 28 have a substantially equal height ; the upper connecting wall, indicated with 30, is bent downwards 90 ° at least in one head of the support 20 and forms a tongue 32 of a height less than said walls
26 and 28.

The free bottom end of the tongue 32 is provided with a central hole 34 with vertical development, which extends for about half the height of one's own tongue, intended to seat a part of the stem of a screw that will be described later. Opposite walls and Parallel support 26 and 28 20 are provided with two slots of step 36, 36 'parallel with ovoid shape, diagonally oriented and obtained in a position near the vertical edges of the same walls. Said grooves 36, 36 ', only visible in relation with the front wall 26 of the support 20, they receive rivets 38, 38 ' respective, inserted transversely in profiled frame 12 properly perforated and in support 20, which is by consequently connected to the same frame 12.

The support 20 is further provided, along of opposite walls 26 and 28, of a passage hole 40 that receives an appropriate rivet 42 to rotatably contract the member rolling 22 in the space between the inner faces of the walls 26 and 28 of the support 20.

The blocking member to prevent disunity of said door of said slide rail 24 is also contracted to said support 20, which consists of a profiled plate preferably made of plastic material provided with an appendix vertically oriented with 24 'end edge protruding towards outside, that is, in the opposite direction in relation to the wall rear 14 of the frame 12. The locking member to prevent the disengagement of said door from said slide rail 24 is secured by rivets 44 or equivalent means to the front wall 26 of support 20 and is intended to cooperate with the bar metal section that will be described later.

The carriage 10 further comprises a block 4 6, made of plastic or other appropriate material, shaped substantially parallelepiped and provided with a threaded hole for a screw 50; said block and screw are shown in detail in figure 10. The screw 50 is provided at the end front of a groove 52 appropriate to be arranged in the recess 34 of the tongue 32 of the support 20, while the block 46 is intended to border the external front of the tongue itself, aligning threaded hole 48 with recess 34. Block 46 is provided with one or more crossing passage holes 54 for fixing thereof to frame 12 and support 20; such fixation is obtained preferably by means of pins 56 with profiled head.

Due to the presence of the passage grooves 36 and 36 'on the support 20, through the connection rivets 38, 38 ', the frame 12 and the support 20 are contracted with the possibility of relative movement among themselves; the rotation in the clockwise or counterclockwise of the screw clock 50, in fact, causes such relative movement since the groove 52 of the screw itself pushes forward or the support 20 related to the frame 12 goes back and these forward and backward movements take place along an inclined direction, determined by the orientation of the 36 and 36 'pitch slots. This advantageously determines the possibility of adjusting the height of the frame 12, therefore the door secured to it, without affecting or otherwise modifying the position of the support 20 carried out by the rolling member 22 and the blocking member to prevent disunity of said door from said sliding rail 24.

As a consequence, the latter remains constantly in an appropriate position in relation to the seat arranged in the section bar comprising the rails sliders

Figures 3 to 5 show a first embodiment of said section bar, indicated globally with 58 and provided with opposite vertical walls with upper edge 60, 60 'with a semi-circular exemplary profile, complementary with respect to the gap formed to along the rolling surface of the rolling member 22. The edge 60 refers to the carriage 12 of the inner door, while the edge 60 'refers to the carriage that will be described later, prepared for the outer door. The section bar 58 defines, between the opposite vertical walls with upper edge 60 and 60 ', two adjacent seats that extend longitudinally and placed at different heights, separator by means of an intermediate wall shaped substantially of an inverted "S" that thanks to two integral horizontal parts, it forms so many biased cuts mounted together; the lower biased cut, indicated with 62, is intended to prevent accidental elevation above the given height of the block member to prevent disengagement of said door from said slide rail 24 and is mounted on the protruding edge 24 'of the same
device.

The default distance between the edge 24 ' and the skewed cut 62 can be advantageously kept constant regardless of the height adjustment of the door secured to the frame 12, thanks to the possibility of moving such frame independently of the support 20 provided with passage grooves 36, 36 'angularly oriented. Also, thanks to the shape and position of the blocking member to prevent disunity of said door of said slide rail 24, the door coupled to the part upper cabinet frame stabilizes easily, taking note that the edge 24 'of said mechanism is arranged automatically below the skewed cut 62. The stage of operation that leads to the coupling and stabilization of the car 12 related to the internal door is schematized in the Figures 3 and 4; where it is seen that by tilting the door first, it is say, keeping the top of it sticking out a bit out, rolling members move around the edge 60 profiled vertical wall sectional bar and edge 24 'of the blocking member to prevent disunity of said door of said slide rail 24 moves below the cut skewed 62. The subsequent alignment of the door, which is also contracted at the bottom by means of any device at cabinet rack, makes the car 12 reinforce and move the 24 'edge at a predetermined minimum distance from the skewed cut 62, thus avoiding accidental disunity of the door.

Figures 6 and 7 refer to a car, indicated globally with 15, prepared for external doors; said carriage comprises several components already illustrated for the solution in Figures 1 and 2 and, consequently, such components are indicated with the same reference numbers used previously. The carriage 15 for external doors comprises a profiled frame 17, similar to the frame 12 of the previous solution compared to which it has a greater width, that is, a greater distance between the rear wall 14 and the front wall 16; such distance is approximately between 40 and 90 mm. According to this embodiment, the support 20 carrying the rolling member 22 and the locking member to prevent disengagement of said door from said sliding rail 24 is secured by means of rivets 38, 38 'to the inner face of the front wall 16 of the profiled frame 17 and to an opposite and parallel wall 19, visible in figures 4 and 5, secured by welding or other appropriate means to the frame 17. The wall 19 is arranged between the front and rear walls 14 of the frame 12 and it develops vertically from the internal front of the flat part that connects the walls themselves. The rivets 38, 38 'cross the inclined grooves 36, 36' made in the front and rear wall 26 of the support 20, which is provided with a block 46 with screw 50 as in the previous embodiment. The block 46 is arranged in the opposite tongue 32 (therefore not visible in Figure 6) in relation to that shown in Figure 2 and thus, is provided with a recess 34 that cooperates with the groove 52 of the screw 50 The supports 20 are actually provided with opposite tabs 32 with recess 34 for use without distinction starting from one head or the other according to the needs of
assembly

The blocking member to prevent disunity of said door of said slide rail 24 is secured, in the solution related to carriage 15 for external doors, to the rear wall 28 of the support 20 by means of rivets 44. In its whole, the frame 17 of the carriage 15 destined for the external door is sized to go beyond frame 12 of carriage 10 intended for the internal door, as can be seen in particular in the figure 5; vertical wall height of section bar 58 provided with an upper edge 60 'is therefore higher than the parallel wall with upper edge 60.

With this configuration, cars 10 and 15 and the respective racks 12 and 17 do not interfere with each other in the assembly stage and during operation.

The blocking member to prevent disunity of said door of said slide rail 24 with 24 'which protrudes outward comprises, in relation to carriage 15, a vertical and opposite appendix, indicated with 21; the second appendix 21 It is smaller than the opposite appendix with an edge protruding 24 'is therefore more elastic. In its whole, the blocking member to prevent disunity of said door of said slide rail 24 associated with carriage 15 defines, in front view, a configuration shaped substantially fork, in which the end of the second appendix 21 protrudes slightly in a direction opposite to the edge 24 'to form a limited extension plane and with final chamfer.

The blocking member to prevent disunity of said door of said slide rail thus obtained It is suitable for a section 58 bar seat extending longitudinally between the wall vertical with upper edge 60 'and the intermediate wall shaped Inverted "S" comprising the lower skewed cut 62. Said device seat 24 associated with carriage 15 is indicated with 65 in figure 5, while the seat of the carriage device 24 12 is indicated with 65 'in the same figure. Top end free of said intermediate wall of section bar 58 is folded 90º in the direction of the edge 60 'and defines accordingly a second skewed cut or upper skewed cut 64, forming a plane barrier protruding from appendix 21.

As with frame 12, the coupling and stabilization along section bar 58 is easy also for carriage 15 related to the external door, tilting the door first, then the car itself, as in Figure 4. The rear alignment of the door makes said car straightens while the locking member to avoid the disengagement of said door from said slide rail 24, the which with the edge 24 'is already in the prepared seat of the bar of section 58, it moves with the second appendix 21 itself seat; the elasticity of the second appendix 21 and the final chamfer of the protruding part of it allow it to be exceeded easily the upper skewed cut 64.

Figures 8, 9, 11, 12 and 13 refer to a alternative embodiment of the carriage for external doors, prepared to use a blocking member to avoid disunity of said door of said slide rail 24 of the type used for the carriage 10 intended for internal doors, in accordance with the Figures 1 and 2.

This embodiment also includes several components identical to those already described and illustrated above, which are therefore indicated with The same reference numbers.

The car illustrated in detail in the figures 8 and 9 is indicated globally with 25 and differs from carriage 15 in which the blocking member to prevent disunity of said door of said slide rail 24 lacks second appendix 21 and it is arranged, in the profiled frame 17, in one more position advanced in relation to the rolling member 22; the latter is for consequently covered in part by the mechanism itself, similar to the solution in figures 1 and 2. Said mechanism 24 is secured by middle of the rivets 4 4 to the front wall 26 of the support 20, while the last one, as in the solution of figures 4 to 7, is arranged and contracted with the rivets 38, 38 that cross the grooves 36, 36 'between the front wall 16 and the wall 19 of the profiled frame 17. Rolling member 22, coupled to the part front 26 and rear 28 by the rivet 42 inserted in the hole 40, is arranged on the same support 20.

The carriage 25 is associated with a section bar specific 59, illustrated in figures 11, 12 and 13, which may also receive the carriage 10, provided with the frame 12 and intended for external doors

As for section bar 58, the section bar 59 comprises two vertical walls with edge upper 60, 60 'with semicircular profile, complementary to the hollow formed along the rolling surface of the rolling member 22

The blocking member to prevent disunity of said door of said slide rail associated with the frames 12 and 17 is in this case identical and corresponds to mechanism 24 with protruding edge 24 'of figures 1 and 2, already which lacks the second appendix 21.

Such members to avoid disunity of said door of said slide rail of frames 12 and 17 is receive in respective seats, substantially identical to each other from the dimensional point of view, made in section bar 59 and separated from each other appropriately.

These seats, indicated with 63 and 63 ', are they obtain at different heights and receive respectively the member blocking to prevent the disengagement of said door from said rail sliding 24 of frame 17 and frame 12; on the side against said mechanisms, seats 63 and 63 'comprise each one a 90º fold that forms so many biased cuts, lower 66 and upper 68, intended to cooperate with the protruding edge 24 ' of the mechanisms themselves. Also in this embodiment, the operations to couple and stabilize the carriages 10 for doors internal and 25 for external doors along the bar section 59 are easy and are obtained according to the procedures already described above.

Figures 14 and 15 refer to another way of realization of the device for sliding wardrobe door according to the invention, which in this case provides only for the use of a member of blocking to prevent the disengagement of said door from said lane of sliding 24 in a carriage for internal and external doors, indicated with 35. Said carriage comprises two profiled frames 37, 39, which support both the rolling member 22 and the member of blocking to prevent the disengagement of said door from said lane of glide; the latter is indicated with 41 in relation to the frame 37 for the external door and with 43 for the frame intended for the internal door. The frame 37 is similar to the frame 17 described above, compared to which it has, in the front vertical wall base indicated with 70, tabs opposite and integral ends 72, bent 90º outward, one of those worn by the blocking member to prevent disunity of said door of said slide rail 41 at the bottom. The same wall 70 constitutes the support for the rolling member 22. The blocking member to prevent disunity of said door from said sliding rail 41 is composed of a body with profile square or "L" in which two planes are oriented substantially at 90º in relation to each and in which the end of the vertical plane extends outward in an appendix integral 41 ', similar to edge 24' of mechanism 24.

The frame 39, arranged at the rear of the frame 37, it is composed of an "L" shaped plate in which the horizontal wall 74 faces the vertical wall 70 of the frame 37 and supports the locking member to avoid disengagement of said door from said slide rail 43 in a extremes; said last, except for the most limited height, is identical to the mechanism 41 of the frame 37 and in this way, it is provided with a final appendix that protrudes out and is indicated with 43 '. The vertical wall 76 of the frame 39 carries the rolling member 22.

The carriage 35 is associated with a bar of section, indicated globally with 78 in figure 15, in which it forms one of the mating edges with a rolling member 22, in particular the one that carries the frame 37, of the sheet of the own one section bar; said edge is indicated with 80 and separates two longitudinally identical extended seats 82, 84, arranged in the same plane, destined respectively to receive the blocking members to prevent disunity of said door from said sliding rail 43 and 41. The edge along which the Rolling member 22 of frame 39 is indicated 80 '. The seats 82 and 84 are provided with skewed cuts 82 'and 84' intended to cooperate with appendices 43 'and 41' of said blocking members to prevent disunity of said door from said sliding rail

Also according to this embodiment of the device for sliding closet door, coupling and stabilization of trolleys 35 is obtained in a fast and easy, starting from the inner secured door to frame 39, according to the same procedures described for the solutions previous.

As you can see from the above, the advantages achieved by the invention are clear. On the device for sliding closet doors of this invention, all blocking members to prevent disunity of said door from said sliding lane are contracted in advance with respect to the car racks and are easily received in the seats respective section bars, provided with biased cuts that prevent the accidental exit of them.
