Definitions

  • the present invention in its most general aspect, relates to movement systems for sliding doors of wardrobes, mainly intended, but not exclusively, for cloth storage or for big furniture.
  • the doors slide in front of the wardrobe structure, along guides arranged at the top and bottom with respect to such structure; the doors slide on spaced apart parallel planes, such that they do not interfere with each other during the movement.
  • the sliding guides for the doors substantially are rails made by means of metal profile members, along which rollers fitted on the doors move; to this end the latter are provided at the top with brackets that essentially have a square-like configuration, with a portion projecting from the upper edge of the door, which supports a corresponding idle roller.
  • brakes can be optionally arranged at the limit stops of the doors, thereby preventing the wardrobe structure from being impacted by slowing the speed of the doors by means of springs and dampers.
  • sliding skids moving along guides arranged at the bottom of the wardrobe, performing a similar function as the upper ones.
  • the weight of the door essentially rests on the upper brackets while the lower skids mainly act for stabilizing the sliding motion, by guiding the lower part of the doors.
  • This solution is effective since it provides a device adjusting the door orientation, which balances the irregularities, if any, in the structure of the door and/or of the wardrobe caused by the assembling or by the (non flat) floor upon which it rests, the humidity that deforms the doors or other factors; however this is not always possible, since there are wardrobes with such a shape or size that do not allow the weight of the doors to be rested mainly at the top wherein upper brackets are provided, or do not allow devices adjusting the door orientation to be installed.
  • the present invention aims at overcoming such prior art; that is to say, it intends to solve the technical problem of providing a piece of furniture with sliding doors such as a wardrobe, a cloth storage or the like, with such structural and functional features to guarantee a regular smooth and precise movement of the doors, even when the wardrobe structure can have defects due to assembling, or to the irregular supporting floor or to any other reasons.
  • the idea for solving this problem is to arrange a wardrobe with a sliding system for the doors, wherein an edge of a door is guided in a balanced manner with respect to stresses acting transversaly thereto; this is particularly valid in case of stresses that tend to tilt or rotate it with respect to its ideal operating (vertical) condition, such as those caused by deformations or small failures of the wardrobe structure mentioned above, or caused by the braking force applied by the devices that slow the door at the limit stops.
  • the wardrobe has a sliding system for a door with rollers arranged in a staggered manner with respect to the sliding direction of the door.
  • the force exerted by the door braking means is preferably applied substantially in the same plane as the rollers, such to be balanced with respect thereto.
  • a sliding system for wardrobe doors is designated by I as a whole.
  • the sliding system 1 comprises a pair of upper guides 4 and lower guides 5, along which the doors 2, 3 move according to respective parallel straight directions.
  • the pair of upper guides 4 is fastened to the upper wall P (or "top") of the wardrobe and it is composed of two grooves 8, 9 defined by corresponding parallel walls 10, 11 and 12, extending from a base 13; the latter is preferably made as one piece with the walls 10, 11, 12 in a single profile member with (reversed) "E"-shaped section made of aluminium, steel or other suitable material, not necessarily metal material (e.g. the guides 4 can be made of strong plastic material with good sliding properties, such as Teflon, polycarbonate, PVC, ABS and the like).
  • the grooves 8, 9 may be made in a separate manner with respective profile members having a "C"-shaped section; moreover, as it will be better understood below, the upper guides 4 can be in the form of rails, that is a male profile member (like the one of the train rails) and therefore different from the grooves (that on the contrary have a female profile) of this example.
  • braking devices 14, 15 respectively may be housed therein which allow the travel of the doors 2, 3 to be slowed down at the limit stop points; the devices 14, 15 (equal to each other) are of the type known per se and each of them comprises a gas damping piston, with a rod (not shown in the drawings) that is connected to a bracket 20, 21 applied to a respective door 2, 3.
  • the brackets 20, 21 are fastened to the outer sliding door 2 and to the inner door 3 of the wardrobe respectively, by means of screws 22; they further have substantially a square shape, with a portion 20a, 21a projecting from the door, and a fastening portion 20b, 21 b where holes for the screws are arranged.
  • Each door is preferably supported by at least a pair of brackets 20, 21 even if in case of big wardrobes three or more brackets can be provided.
  • the brackets 20 located on the outer door 2 have greater dimensions, as regards the projecting portion 20a, which, according to a preferred embodiment, is length adjustable.
  • a roller-holder support 24 is secured, in an adjustable manner, by means of a series of holes 23 and 25 arranged on the projecting portion 20b of the bracket and on the support 24 respectively: the holes 23 and 25 are arranged in not-rectilinear patterns, such that it is possible to adjust the position of the support 24 with respect to the bracket 20 by superimposing the holes 25 of the former on those on the latter and by securing them by means of screws 26, even by changing the angle orientation of the support 24.
  • the latter is provided with two idle rollers 30 arranged in a staggered manner with respect to the plane of the door 2, that is having different distances therefrom such that when the door is fitted on the wardrobe, they slide into the groove 8 rolling on the walls 10 and 11 thereof respectively.
  • rollers 30 allow them to be kept in contact with the walls 10 and 11 of the groove 8, even in case of defects of the wardrobe or of the door 2, in case of deformations, failures or any other things that can change the orientation thereof from the normal condition with the plane of the door parallel to the sliding direction.
  • the staggered arrangement of the rollers 30 allow the clearances with the groove 8 to be recovered, keeping the door 2 in its vertical plane parallel to the sliding direction (defined by the guide 4) preventing it from rotating with respect to a vertical axis.
  • the staggered rollers 30 prevent the door 2 from being positioned in a inclined position with respect to the sliding direction, since they do not allow it to rotate as on the contrary is the case of only one roller according to what occurs in the prior art.
  • the bracket 20 is provided with an appendage 31 arranged in a position intermediate between the rollers 30; to such appendage a movable end of the damping device 14 is connected, that, as already said, is of the type known per se, for example as those produced by the same applicant of the present application which have one movable rod associated to a cylinder wherein a fluid (air or gas) is provided that viscously slows down the travel thereof.
  • a fluid air or gas
  • One end of the rod extends out from the cylinder of the device 14 and is connected to the appendage 31 upon which it exerts the braking force: since the appendage 31 is in a central position with respect to the support 24 and the rollers 30, the force applied thereon is balanced and therefore it minimizes the stresses in the several components of the bracket 20 and of the guide 4.
  • the central position of the appendage 31 is possible thanks to the rollers 30 being staggered, since should the latter be aligned the appendage would not be connectable to the braking device 14 and therefore it should be situated in a side or front area with respect to the bracket, such that the force applied by the device 14 would be inevitably unbalanced.
  • brackets 21 secured to the inner door 3 Similar considerations are also valid for the brackets 21 secured to the inner door 3: the fact that they are shorter than the previous ones (that are arranged thereon as a bridge as it can be seen in figure 3 ) does not change the essence of things.
  • brackets 21 have a square shape with a projecting portion 21a and a fastening one 21b with the holes for the screws 22; according to a preferred embodiment the bracket 21 is obtained by the support 24, where the fastening portion 21b is obtained by a moulding bending or other suitable mechanical treatment.
  • brackets 21 are provided with a pair of staggered rollers 32, with the relevant effects already explained above; the rollers 32 engage the groove 9 by rolling on the walls 11, 12 that laterally delimit it, such to assist the sliding of the inner door 3 of the wardrobe.
  • An appendage 33 is further provided on the bracket 21 to which the braking device 15 is connected, with the same results achieved by the other bracket 20 mentioned above.
  • the weight of the doors 2 and 3 rests on the pair of lower guides 5, that comprise grooves 38, 39 as well along which the rollers 40 of the carriages 41 provided at the lower edge of the doors 2 and 3 can move.
  • the carriages 41 are all equal to each other and comprise an outer structure or case 42 wherein the roller 40 is housed in an idle manner; the structure 42 of the carriage is fitted into a corresponding seat formed in the doors in a manner known per se.
  • the position of the support 24 of the brackets 20 can be adjusted by the screws 26 in the holes 23; thus also the orientation of the outer door 2 is adjusted as desired, such to eliminate possible situations of interference with the inner door 3.
  • the provision of the staggered rollers 30, 32 on the brackets 20, 21 allow the clearances along the grooves 8 and 9 to be recovered, such that the sliding of the doors is made more regular even considering that their travel is slowed down by the devices 14, 15.
  • the latter act on the appendages 31, 33 of the brackets 20, 21 that have a central position with respect thereto, such to limit the structural stresses resulting from braking forces: it results that the motion of the doors 2, 3 is more regular and reliable even over time, since the forces applied on the brackets 20, 21 are more balanced.
  • the respective pairs of staggered rollers 30, 32 of the brackets 20, 21, in addition to recovering the clearances with the guides 4 and 5 constitute also a constraint for their free end that transmits also a momentum, which opposes the one that tends to stress the brackets after the braking action.
  • the braking devices 14, 15 can be advantageously housed into the grooves 8, 9 along which the rollers 30, 32 move.
  • the number of the brackets can be different than the pair shown in the figures; even if this is the preferred solution, in principle by the presence of the staggered rollers the use of only one bracket for one door could be enough, since they allow the rotations of the door with respect to the vertical axis to be limited anyway.
  • rollers 30, 32 for a bracket 20, 21: for instance it may be possible to have three (or more) of them arranged in a staggered manner (quincunx) such to increase the stability of the support of the door in the relevant guide 4, 8, 9.
  • the guides can be configured as rails instead of grooves, and consequently even the rollers shall have a different profile (e.g. like the one of the train rails).
