Description

This invention relates to a wardrobe sliding door arrangement, and in particular to a sliding rail with a locking member for preventing the disengagement of said door from said sliding rail with automatic engagement and disengagement from the respective rail.
More in particular, this invention relates to a guide as defined above wherein the locking member for preventing the disengagement of said door from said sliding rail is easily insertable and removable from the sliding rail seat without the need of using any tools at all, and moreover is constantly kept into the most suitable position into said rail seat irrespective of the height adjustment of the wardrobe door.
Furniture provided with sliding doors is nowadays much widespread and appreciated, as it allows eliminating the obstructions due to the projection of the doors themselves in the opening step. Also from the aesthetic point of view, furniture with sliding doors has an appreciable advantage due to the lack of hinges that could remain at least partly visible and alter the linearity of the furniture itself.
Specific devices are generally used to obtain the sliding of furniture doors, which consist in small carriages comprising wheels, sliding blocks, bearings or the like; the carriages are constrained to the doors at the top edge of the same and through said rotatable members, they slide along rails or seats formed into suitably shaped metal section bars. The section bars are secured to the carrying frame of the furniture, in the proximity of the front side of the same both at the top and at the bottom, and in general they comprise two paired sliding seats for as many doors or groups of doors, internal and external. In the assembly step, the single doors provided with carriage are first hooked to the top rail whereto they remain hung but with the possibility of oscillating; immediately afterwards, the device located in the bottom side of the door is brought to insert into the corresponding seat, suitably moving the door itself.
The coupling of the internal and external doors with the arrangement of the respective carriages along the seats of the metal section bars arranged at the top is not particularly difficult; on the contrary, the subsequent attachment of a locking member for preventing the disengagement of said door from said sliding rail is very difficult due to the position of the carriages themselves close to the ceiling, it does not allow visual checks to the operator and often causes an imprecise operation. In these conditions, handling the tools required for locking the locking member for preventing the disengagement of said door from said sliding rail is further difficult. If the latter is not properly arranged onto the carriage, the risk that the door may detach from the piece of furniture and get damaged is real; considering that the doors often have a considerable weight, the accidental disengagement thereof may cause serious harm to people. The locking member for preventing the disengagement of said door from said sliding rail is difficult to apply to the carriage in the door assembly step and sometimes it is even more difficult to remove in the event of removal of the door itself.
Moreover, the non-secondary drawback related to the fact that the locking member for preventing the disengagement of said door from said sliding rail is secured to the door carriage and that the latter often requires height adjustments, should be taken into account. To this end the carriage, which is provided with adjustment slots in relation to the door, is operated but in many cases altering the correct position of the locking member for preventing the disengagement of said door from said sliding rail.
An upward or downward movement of the carriage necessarily involves also the locking member for preventing the disengagement of said door from said sliding rail, whose effects could thus be nullified, putting the door stability at a risk.
The object of this invention is to obviate the drawbacks mentioned hereinabove.
More in particular, the object of this invention is to provide a wardrobe sliding door arrangement wherein the top carriage of the doors themselves, integrating the locking member(s) for preventing the disengagement of said door from said sliding rail, is engageable or disengageable in a substantially automatic manner, without the aid of tools, from the respective sliding rail.
Further and not secondary object of the invention is to provide a wardrobe sliding door arrangement as defined above wherein the position of the locking member(s) for preventing the disengagement of said door from said sliding rail is not influenced by the movement in vertical direction of the top carriage of the door, carried out for adjusting the height of the door itself.
Last but not least, an object of the invention is to provide a wardrobe sliding door arrangement wherein the locking member for preventing the disengagement of said door from said sliding rail associated to the top carriage of the doors is automatically positioned, and without the need of tools, into the seat created in the section bar secured to the bearing frame.
A further object of the invention is to provide the users with a wardrobe sliding door arrangement suitable for ensuring high level of resistance and reliability over time, also such as to be easily and inexpensively constructed.
These and yet other objects are achieved by a wardrobe sliding door arrangement according to claim 1. Further advantageous features of the invention are described in the dependent claims.

With reference first to figures 1, 2 and 3, a wardrobe sliding door arrangement according to this invention comprises a carriage, globally indicated with 10 at figure 1 and intended for internal and external doors, composed of a shaped frame 12 having a section substantially as an upturned "U", wherein the opposite and parallel back 14 and front 16 walls have different heights. In particular, the back wall 14 of the frame 12 is intended to be secured to the wardrobe door (not shown) by conventional screws and is therefore provided with multiple through holes 18. The distance between said walls 14 and 16 is approximately comprised between 15 and 40 mm and defines, in the central-top portion of the frame 12, a cavity with rectangular profile and longitudinally extended, wherein a support 20 is arranged for a rotatable member 22, provided with central through hole 22', and for a locking member for preventing the disengagement of said door from said sliding rail 24. The support 20 defines an upturned "U" profile wherein the opposite and parallel front 26 and back 28 walls have a substantially equal height; the top connecting wall, indicated with 30, is bent downwards at 90° at least on a head of the support 20 and forms a tab 32 of smaller height than said walls 26 and 28.
The bottom free end of the tab 32 is provided with a central recess 34 with vertical development, extending by about half the height of the tab itself, intended for seating a part of the stem of a screw which shall be described hereinafter. The opposite and parallel walls 26 and 28 of support 20 are provided with two parallel through slots 36, 36' of ovoid shape, diagonally orientated and obtained in a position close to the vertical edges of the same walls. Said slots 36, 36', only visible relative to the front wall 26 of the support 20, receive respective rivets 38, 38', inserted transversally into the suitably pierced shaped frame 12 and in the support 20, which is therefore connected to the same frame 12.
The support 20 is further provided, along the opposite walls 26 and 28, with a through hole 40 that receives a rivet 42 suitable for rotatably constraining the rotatable member 22 into the space comprised between the internal faces of the walls 26 and 28 of the support 20.
The locking member for preventing the disengagement of said door from said sliding rail 24 is also constrained to said support 20, which consists in a shaped plate preferably made of plastic material provided with an appendix vertically orientated with end lip 24' protruding outwards, that is, in opposite direction relative to the back wall 14 of the frame 12. The locking member for preventing the disengagement of said door from said sliding rail 24 is secured by rivets 44 or equivalent means to the front wall 26 of the support 20 and is intended for cooperating with the metal section bar that will be described hereinafter.
The carriage 10 further comprises a block 46, made of plastic or other suitable material, with substantially parallelepiped shape 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 front end with a groove 52 suitable for arranging into the recess 34 of the tab 32 of the support 20, whereas the block 46 is intended for abutting the external front of the tab itself, aligning the threaded hole 48 with the recess 34. The block 46 is provided with one or more cross through holes 54 for the fixing thereof to the frame 12 and to the support 20; such fixing is preferably obtained by pins 56 with shaped head.
Due to the presence of the through slots 36 and 36' on the support 20, through the connecting rivets 38, 38', the frame 12 and the support 20 are constrained to each other with possibility of relative motion between each other; the rotation in clockwise or counter clockwise direction of the screw 50, in fact, originates such relative movement since the groove 52 of the screw itself pushes forward or retracts the support 20 relative to the frame 12 and these forward and backward movements take place along an inclined direction, determined by the orientation of the through slots 36 and 36'. This advantageously determines the possibility of adjusting the height of the frame 12, thus the door secured thereto, on the other hand without affecting and modifying the position of the support 20 that carries the rotatable member 22 and the locking member for preventing the disengagement of said door from said sliding rail 24.
As a consequence, the latter remains constantly into the suitable position in relation to the seat arranged on the section bar comprising the sliding rails.
Figures 3 to 5 show a first embodiment of said section bar, globally indicated with 58 and provided with opposite vertical walls with top edge 60, 60' with a profile by way of an example semicircular, complementary to the recess formed along the rolling surface of the rotatable member 22. The edge 60 is referred to the carriage 12 of the internal door, whereas the edge 60' is referred to the carriage that will be described hereinafter, set up for the external door. The section bar 58 defines, between the opposite vertical walls with top edge 60 and 60', two adjacent seats extended longitudinally and placed at different heights, separated by an intermediate wall substantially shaped as an upturned "S" that thanks to two integral horizontal portions, forms as many undercuts overlapped to each other; the bottom undercut, indicated with 62, is intended for preventing the accidental lifting above a given height of the locking member for preventing the disengagement of said door from said sliding rail 24 and is overlapped to the protruding lip 24' of the device itself.
The predetermined distance between the lip 24' and the undercut 62 can be advantageously kept constant irrespective of the height adjustment of the door secured to the frame 12, thanks to the possibility of moving such frame irrespective of the support 20 provided with orientated angularly through slots 36, 36'. Moreover, thanks to the shape and position of the locking member for preventing the disengagement of said door from said sliding rail 24, the door coupled to the top portion of the wardrobe frame is easily stabilised, considering that the lip 24' of said device automatically arranges below the undercut 62. The operating step that leads to the coupling and stabilisation of the carriage 12 relative to the internal door is schematised at figures 3 and 4; wherefrom it is seen that by first inclining the door, that is, keeping the top portion thereof slightly protruding outwards, the rotatable member moves on the shaped edge 60 of the vertical wall of the section bar and the lip 24' of the locking member for preventing the disengagement of said door from said sliding rail 24 is moved underneath the undercut 62. The subsequent alignment of the door, which is constrained also at the bottom by any device to the wardrobe frame, makes the carriage 12 straighten up and moves the lip 24' to a predetermined and minimum distance from the undercut 62, thus preventing the accidental disengagement of the door.
Figures 6 and 7 refer to a carriage, globally indicated with 15, set up for the external doors; said carriage comprises several components already illustrated for the solution at figures 1 and 2 and therefore, such components are indicated with the same reference numerals used before. The carriage 15 for external doors comprises a shaped frame 17, similar to frame 12 of the previous solution compared to which it has a larger width, that is, a larger distance between the back wall 14 and the front wall 16; such distance is approximately comprised between 40 and 90 mm. According to this embodiment, the support 20 carrying the rotatable member 22 and the locking member for preventing the disengagement of said door from said sliding rail 24 is secured by the rivets 38, 38' to the internal face of the front wall 16 of the shaped frame 17 and to an opposite and parallel wall 19, visible at figures 4 and 5, secured by welding or other suitable means into the frame 17. The wall 19 is arranged between the front 16 and back 14 walls of the frame 12 and develops in vertical from the internal front of the flat portion that connects the walls themselves. The rivets 38, 38' cross the inclined slots 36, 36' made on the front 26 and back 28 wall of the support 20, which is provided with block 46 with screw 50 as in the previous embodiment. The block 46 is arranged at the opposite tab 32 (thus not visible at figure 6) relative to that shown at figure 2 and like that, it is provided with a recess 34 cooperating with the groove 52 of the screw 50. The supports 20 are actually provided with opposite tabs 32 with recess 34 to be used without distinction starting from one or the other head according to the assembly needs.
The locking member for preventing the disengagement of said door from said sliding rail 24 is secured, in the solution relating to the carriage 15 for external doors, to the back wall 28 of the support 20 by rivets 44. As a whole, the frame 17 of the carriage 15 intended for the external door is sized so as to go beyond the frame 12 of the carriage 10 intended for the internal door, as can be seen in particular at figure 5; the height of the vertical wall of the section bar 58 provided with top edge 60' therefore is higher than the parallel wall with top edge 60.
With this configuration, the carriages 10 and 15 and the respective frames 12 and 17 do not interfere with each other in the assembly step and in operation.
The locking member for preventing the disengagement of said door from said sliding rail 24 with 24' protruding outwards comprises, relative to the carriage 15, a second and opposite vertical appendix, indicated with 21; the second appendix 21 has a smaller width than the opposite appendix provided with protruding lip 24' therefore is more elastic. As a whole, the locking member for preventing the disengagement of said door from said sliding rail 24 associated to the carriage 15 defines, in front view, a substantially fork-wise configuration, wherein the end of the second appendix 21 is slightly protruding in a direction opposite the lip 24' for forming a limited extension plane and with end chamfer.
The locking member for preventing the disengagement of said door from said sliding rail thus obtained is suitable for arranging in a longitudinally extending seat of the section bar 58 comprised between the vertical wall with top edge 60' and the intermediate wall shaped as an upturned "S" that comprises the bottom undercut 62. Said seat of the device 24 associated to the carriage 15 is indicated with 65 at figure 5, whereas the seat of the device 24 of the carriage 12 is indicated with 65' at the same figure. The top free end of said intermediate wall of the section bar 58 is bent at 90° in the direction of the edge 60' and therefore defines a second undercut, or top undercut 64, forming a barrier for the protruding plane of the appendix 21.
As with the frame 12, the coupling and stabilisation along the section bar 58 is easy also for the carriage 15 relating to the external door, by first inclining the door, then the carriage itself, as in figure 4. The subsequent alignment of the door makes said carriage straighten up, whereas the locking member for preventing the disengagement of said door from said sliding rail 24, which with the lip 24' is already into the set up seat of the section bar 58, moves with the second appendix 21 into the seat itself; the elasticity of the second appendix 21 and the end chamfer of the protruding portion thereof allow easy surpassing of the top undercut 64.
Figures 8, 9, 11, 12 and 13 relate to an alternative embodiment of the carriage for external doors, set up for using a locking member for preventing the disengagement of said door from said sliding rail 24 of the type used for the carriage 10 intended for internal doors, as per figures 1 and 2.
Also this embodiment comprises several components identical to those already described and illustrated before, which are therefore indicated with the same reference numerals.
The carriage illustrated in detail at figures 8 and 9 is globally indicated with 25 and differs from the carriage 15 in that the locking member for preventing the disengagement of said door from said sliding rail 24 lacks the second appendix 21 and is arranged, on the shaped frame 17, in a more advanced position relative to the rotatable member 22; the latter is therefore partly covered by the device itself, similar to the solution at figures 1 and 2. Said device 24 is secured by the rivets 44 to the front wall 26 of the support 20, while the latter, as in the solution of figures 4 to 7, is arranged and constrained with the rivets 38, 38 that cross the slots 36, 36' between the front wall 16 and the wall 19 of the shaped frame 17. The rotatable member 22, coupled to the front 26 and back 28 by the rivet 42 inserted in the hole 40, is arranged into the same support 20.
The carriage 25 is associated to a specific section bar 59, illustrated at figures 11, 12 and 13, which can receive also the carriage 10, provided with frame 12 and intended for the external doors.
As for section bar 58, the section bar 59 comprises two vertical walls with top edge 60, 60' with semicircular profile, complementary to the recess formed along the rolling surface of the rotatable member 22.
The locking member for preventing the disengagement of said door from said sliding rail associated to the frames 12 and 17 is in this case identical and corresponds to the device 24 with protruding lip 24' of the figures 1 and 2, as it lacks the second appendix 21.
Such locking members for preventing the disengagement of said door from said sliding rail of the frames 12 and 17 are received into respective seats, substantially identical to one another from the dimensional standpoint, made in the section bar 59 and suitably spaced from each other.
Said seats, indicated with 63 and 63', are obtained at different heights and respectively receive the locking member for preventing the disengagement of said door from said sliding rail 24 of the frame 17 and of the frame 12; on the side facing said devices, the seats 63 and 63' comprise each a bending at 90° that forms as many undercuts, bottom 66 and top 68, intended for cooperating with the protruding lip 24' of the devices themselves. Also in this embodiment, the operations for coupling and stabilising the carriages 10 for internal doors and 25 for external doors along the section bar 59 are easy and are obtained according to the methods already described before.
Figures 14 and 15 refer to a further embodiment of the wardrobe sliding door arrangement according to the invention, which in this case envisages only the use of locking member for preventing the disengagement of said door from said sliding rail 24 on a carriage for internal and external doors, globally indicated with 35. Said carriage comprises two shaped frames 37, 39, that support both the rotatable member 22 and the locking member for preventing the disengagement of said door from said sliding rail; the latter is indicated with 41 relative to the frame 37 for the external door and with 43 for the frame 39 intended for the internal door. The frame 37 is similar to the frame 17 described before, compared whereto it has, at the base of the front vertical wall indicated with 70, opposite and integral end tabs 72, bent at 90° outwards, one of which carries the locking member for preventing the disengagement of said door from said sliding rail 41 at the bottom. The same wall 70 constitutes the support for the rotatable member 22. The locking member for preventing the disengagement of said door from said sliding rail 41 is composed of a body with square or "L" profile wherein the two planes are orientated substantially at 90° relative to each other and wherein the end of the vertical plane extends outwards in an integral appendix 41', similar to lip 24' of the device 24.
The frame 39, arranged at the back of frame 37, is composed of a plate shaped as an "L" wherein the horizontal wall 74 faces the vertical wall 70 of the frame 37 and supports the locking member for preventing the disengagement of said door from said sliding rail 43 at an end; said latter, except for the more limited height, is identical to the device 41 of the frame 37 and like that, it is provided with end appendix protruding outwards and indicated with 43'. The vertical wall 76 of the frame 39 carries the rotatable member 22.
The carriage 35 is associated to a section bar, globally indicated with 78 at figure 15, wherein one of the coupling edges with a rotatable member 22, in particular that carried by the frame 37, is formed from the folding of the section bar itself; said edge is indicated with 80 and separates two identical longitudinally extended seats 82, 84, arranged on the same plane, respectively intended for receiving the locking members for preventing the disengagement of said door from said sliding rail 43 and 41. The edge wherealong the rotatable member 22 of the frame 39 slides is indicated with 80'. The seats 82 and 84 are provided with undercuts 82' and 84' intended for cooperating with the appendices 43' and 41' of said locking members for preventing the disengagement of said door from said sliding rail.
Also according to this embodiment of the wardrobe sliding door arrangement, the coupling and the stabilisation of the carriages 35 are obtained in a quick and easy manner, starting from the internal door secured to the frame 39, according to the same methods described for the previous solutions.
As can be noticed from the above, the advantages achieved by the invention are clear. In the wardrobe sliding door arrangement of this invention, all the locking members for preventing the disengagement of said door from said sliding rail are constrained beforehand to the carriage frames and are easily received into the respective seats of the section bars, provided with undercuts that prevent the accidental exit thereof.
Particularly advantageous, with reference to the solutions shown at figures 1 to 13, is the possibility of adjusting the height of the doors without influencing or modifying the position of the locking members for preventing the disengagement of said door from said sliding rail constrained to the different carriages.
Even if the invention has been described hereinbefore with particular reference to some embodiments thereof made by way of a non-limiting example only, several changes and variations will appear clear to a man skilled in the art in the light of the above description.
This invention therefore is intended to include any changes and variations thereof falling within the spirit and the scope of protection of the following claims.
