- the doors are also provided with fifth guide and synchronism means cooperating with said third upper support and slide means and fourth support and slide means to enable respectively said upper and lower portion of the doors to slide in a synchronized manner transversally in the depth direction of the cabinet to and from said closed and opened position of the same doors.
- the object of the present invention is to provide a support and actuation arrangement for slidable doors of wardrobes and similar cabinets, which makes use of mechanisms that are made in a manner different than those disclosed by CH 616720 A5 .
- a support and actuation arrangement for the sliding doors of wardrobe cabinets according to a preferred embodiment of the present invention, which is made and operates in the manner as described below, and which is adapted to support and slidably actuate the cabinet doors in alternate longitudinal directions into mutually co-planar positions, wherein such doors are actuated at the same time and move from a closed position, in which the doors are close to each other and aligned with each other relative to the front plane of the wardrobe cabinet, to an opened position, in which such doors are first shifted slightly forwards and then caused to slide sideways into the desired position in a parallel relation with the front plane of the wardrobe cabinet.
- each such cabinet is shown to incorporate the door support and -actuation arrangement according to the present invention, wherein each such wardrobe cabinet 5 in the illustrated example is provided with a front planar door 6 provided with two side door handles 7 and 8 for shifting the door and cause it to slide in an alternate longitudinal direction; in the above-cited illustrations, the doors 6 of all cabinets 5 are shown to be shifted into their closed position, in which they are arranged so as to lie aligned with each other, thereby forming a smooth planar front face of the cabinet assembly.
- each wardrobe cabinet 5 is delimited by a rear wall 9 extending parallel to the door 6, a planar top ceiling 10, a planar lower bottom 11, and two side walls, wherein in the example illustrated in Figures 1 to 4 there can be noticed the outer side walls 12 and 13 delimiting the two outer sides of the corresponding cabinets joined with each other, and two inner side walls 14 and 15 delimiting each cabinet in the assembly.
- one of the cabinet doors, and namely the door of the middle cabinet in the example illustrated is shown to be shifted into a half-opened position thereof in the manner as described in greater detail further on.
- the first component part is substantially formed of a metal profile section 16 (see Figures 5 and 6 ) having the same length as each door 6 and configured to include a vertical rectilinear planar portion 17, which is fixedly secured to the upper portion of each door by means of screws 18 and bent inwardly, i.e.
- first component part being further comprised of an angle metal section 21 in an elongated rectilinear shape, which has the same length as the profile section 16 and is configured to include a horizontal portion 22, which is secured to the front edge of the ceiling 10 of the cabinet, and an upwards facing short vertical portion 23, so as to be able to guide the alternate longitudinal sliding movement of the upper portion of the door 6 in the manner that shall be described in greater detail further on.
- the second component part is substantially comprised of an angle section 24 of metal or thermoplastic material (see Figures 7 and 8 ), having a rectilinear horizontal extension over a same length as the length of each door 6 and so shaped as to include a short horizontal portion 25, which is joined to the lower portion of each door 6 by means of brackets 26, and which is bent upwards to form a short vertical portion 27 acting as a guide, or runner, for the door to be able to perform the alternate longitudinal sliding movement thereof in the manner that shall be described in greater detail further on.
- the third component part is substantially comprised of a robust vertical metal profile section 28 (see Figures 9 and 10 ) having a length that is equal to the height of the cabinet, which is secured in an intermediate position against the rear wall 9 of each cabinet so as to extend all over the height of such rear wall (see also Figure 2 ), wherein the upper and lower end portions thereof are bent horizontally and configured in the manner and to the purposes that shall be described and explained in greater detail further on.
- the fourth component part is substantially comprised of an upper skid 29 (see Figure 11 and 12 ) adapted to allow the upper portion of each door 6 to perform the alternate longitudinal sliding movement thereof and substantially comprised of an elongated rectilinear metal profile section 30 having a length that is slightly shorter than the length of each door 6 and so shaped as to include a front planar edge 31 in which there are pivotally hinged, in a freely rotatable manner, various rather thin wheels 32 regularly spaced from, similar to and aligned with each other, which are adapted to slide in an alternate longitudinal direction along the corresponding groove 20 in the profile section 19 that is secured, jointly with the profile section 16, to the upper portion of each door 6.
- This elongated rectilinear metal profile section 30 is further provided with two side wheels 33, which are similar to each other and are pivotally hinged in a freely rotatable manner at the side end portions of the same profile section in an orthogonal position relative to the above-cited wheels 32; additionally, it is also provided with two further wheels 34, similar and situated close to each other, that are pivotally hinged in a freely rotatable manner in the lower planar edge 35 of the profile section with a downward-facing orientation, wherein all these wheels are provided to the purposes that shall be described in greater detail further on.
- the elongated profile section 30 of the above-described skid is further joined with a middle rectilinear transverse profile section 36 that is bent downwards so as to delimit an inner cavity opening downwards, wherein such profile section is arranged orthogonally to said elongated profile section, at the rear thereof, thereby forming a T-shaped structure, and extends over the entire depth of each cabinet; between these profile sections 30 and 36 there is further secured a reinforcement and stiffening structure formed of two inclined profile sections 37 and 38 in a mutually symmetrical arrangement.
- the free rear end portion of the transverse profile section 36 is inserted onto the corresponding bent upper end portion of the vertical profile section 28, by which it is therefore supported, and this end portion of the vertical profile section 28 is provided with an actuation mechanism that is so shaped and configured as this shall be described in greater detail further on, wherein such mechanism is adapted to cause the assembly formed by the transverse profile section 36 and the skid 29 to displace, jointly with the door 6, by just a limited extent in the alternate transversal direction of each cabinet.
- the upper skid 29 is laid to rest upon and fixed with the lower edge 35 thereof to the planar horizontal portion 22 of the angle section 21 and cannot displace from such position owing to the side wheels 33 thereof, which are resting against corresponding raised portions 39 of such planar horizontal portion 22 of the angle section 21, and the lower wheels 34 thereof, which engage, on both sides thereof, a middle rib 40 provided transversally on the same planar horizontal portion of the angle section, and owing also to the upper skid 29 being laterally delimited by the vertical section portion 23 and a further short vertical portion 41 of the afore-cited profile section 16 formed along the other side edge of the above-cited planar horizontal section portion 22 in a position lying parallel to said vertical section portion 23.
- the upper skid 29 is kept in this position also by means of the transverse profile section 36 joined to the same skid, the free rear end portion of which is caused to pass through a bracket 42 attached to the ceiling 10 of the cabinet, by which such profile section 36 is therefore supported, and in this bracket 42 there are pivotally hinged in a freely rotatable manner and in mutually opposing positions two vertical-axis idle wheels 43 and 44 acting from both sides against the related side surface of the transverse profile section 36, to the purpose of guiding the sliding movement of the profile section in the transversal direction of the cabinet, in the manner and to the purposes that shall be described in greater detail further on, as well as preventing the same profile section from displacing in the longitudinal direction of the cabinet.
- the longitudinal sliding movement of the door 6 in each cabinet occurs by placing the profile section 16 supporting the door 6 in a position above and corresponding to the upper skid 29, while fitting all idle wheels 32 of such skid in the groove 20 defined by the vertical profile section 19.
- this profile section 19 will then be able to slide on all above-cited idle wheels in the longitudinal direction of the cabinet, wherein it will, be guided in this sliding movement thereof by a guide plane formed of a sequence of regularly spaced guide wheels 45 provided in a mutually aligned arrangement and pivotally hinged in a freely rotatable manner in the vertical portion 23 of such angle section 21 in positions that are parallel to the ones of the wheels 32 of the upper skid.
- the skid 29-transverse profile section 36 assembly is displaced forwards in the transverse direction of the cabinet, jointly with the door 6, and shifted into the position illustrated in Figure 39 , in which the vertical profile section 19 and the related groove 20 come to be also aligned with the idle wheels 45 of the angle section 21, so that, in this position, to be engaged in the groove 20 of the vertical profile section 19 there are not solely the wheels 32 of the upper skid 29, but also the wheels 45 of the angle section 21, during the longitudinal sliding movement of the profile section 19 and, as a result, the door 6 shifted into the opened position thereof lying over the front plane of the cabinet in front thereof.
- the same door can be of course caused to slide back into the afore-described closed position thereof in the reverse sequence of the above-described movements.
- This fifth component part is substantially comprised of a lower skid 46 adapted to allow the lower portion of each door 6 to perform the alternate longitudinal sliding movement thereof and substantially comprised of an elongated angle section 47 having the same length as the door and located in a position lying under the bottom 11 of the cabinet, this elongated angle section being further shaped so as to include a planar vertical portion 48 that is bent at the upper portion thereof to form a short horizontal planar portion 49, said elongated angle section being further provided in the middle region thereof with two similar idle wheels 50 situated close to each other and pivotally hinged in a freely rotatable manner, and being joined with a transverse profile section 51 arranged orthogonally to said elongated profile section, at the rear thereof, thereby forming a T-shaped structure, and extends over the entire depth of each cabinet; as in the preceding case, between these profile sections 47 and 51 there
- the free rear end portion of the transverse profile section 51 is inserted onto the corresponding bent lower end portion of the vertical profile section 28, by which it is therefore supported, and this end portion of the vertical profile section 28 is provided with an actuation mechanism similar to the afore-considered upper one, as this shall anyway be described in greater detail further on, adapted to cause the assembly formed by the transverse profile section 51 and the lower skid 46 to displace, jointly with the door 6, by just a limited extent in the alternate transversal direction of each cabinet, synchronously with the movement of the upper assembly formed of the transverse profile section 36 and the upper skid 29.
- each such shoe is shaped so as to include a rectilinear shank 56, which is applied and appropriately secured against said front angle-section surface, as well as two short side shanks 57 similar to each other and projecting forwards from the same section, said side shanks being so spaced from each other as to form a free space therebetween, in which there is accommodated a related idle roller 58 supported by a short arm 59 secured against the angle section 47 and provided there to the purposes that shall be described in greater detail further on
- a slit 60 extending thereunder and through all such slits 60 of the shoes 54 and 55 there is fitted the vertical portion 27 of the angle section 24, which is joined against the lower portion of the door 6, so that the same door is allowed to slide in the longitudinal direction through all slits 60, which therefore
- an angle section 61 having the same length as said skid, wherein this angle section is so shaped as to include a horizontal planar portion 62, having a greater width than the horizontal portion 49 of the skid 46 thereunder, and a vertical and front planar portion 63, wherein the horizontal portion 62 of the angle section 61 is provided with side flanks 64 and 65 that are so bent as to form a respective short horizontal planar border 66 and 67; these borders are fitted onto the corresponding side end portion of the horizontal portion 49 of the lower skid 46 lying thereunder, thereby joining the angle section 61 lying thereabove and said skid 46 with each other.
- the upper wheels 50 of the lower skid 46 come to rest against the sides of a transverse rib 68 formed in the lower surface of the horizontal portion 62 of the angle section under the bottom 11 of the cabinet.
- each such shoe is comprised of a respective rear quadrangular plate 71 (see Figures 35 to 37 ) attached against the vertical angle-section portion 63, as well as a front moveable quadrangular plate 72, which is arranged above the rear plate 71 and supported by the latter so as to be able to slide relative thereto by a limited extent in the vertical direction, by means of a linkage system of a kind largely known as such in the art, along corresponding vertical guides 73 provided on the same rear plate, wherein both such plates are made so as to have a width enabling them to fit into the free space defined between the side shanks 57 of the respective shoes 54 and 55, and each movable front plate 72 is so shaped over the entire width thereof to include a rear and lower front recess 74 (see also Figures 32 and 33 ) and a thin projecting front
- Each front plate 72 is furthermore provided with an upper receptacle 77 adapted to receive and accommodate the end portion of a corresponding compression spring 78, the other end, portion of which is accommodated in the lower surface of the horizontal angle-section portion 62, and this movable front plate is displaceable from a lowered position thereof, as illustrated in Figures 8 , 15 and 33 , in which it is biased into such position by the spring 78 when the door 6 is shifted in the closed position thereof, to the raised position thereof shown in Figure 32 against the action of said spring 78, which is compressed, when the door 6 is shifted into the opened position thereof.
- the lower skid 46 is kept in the above-described position also by the effect of the transverse profile section 51 joined to the same skid and bent upwards to delimit an inner cavity opening upwards, and the free rear end portion of such transverse profile section 51 is caused to pass through a bracket 79, similar to and arranged symmetrically relative to the previously described bracket 42, which is attached to both the bottom 11 of the cabinet and the profile section 51, and pivotally hinged in a freely rotatable manner to such bracket 79 in mutually opposing positions there are two vertical-axis idle wheels 80 and 81 acting from both sides against the related side surface of the transverse profile section 51, and also in this case there occurs a sliding movement of the profile section by just a limited extent in the transversal direction of the cabinet, in the manner and to the purposes that shall be described in greater detail further on, while the same profile section is prevented from displacing in the longitudinal direction of the cabinet.
- FIG. 16 to 23 there is this sixth component part in a first embodiment thereof, wherein it can be noticed to be substantially comprised of a first upper horizontal-axis cylindrical roller 82 pivotally hinged in a rotatable manner between two parallel and mutually spaced shanks 83 and 84 of a metal bracket 85 attached to the upper end portion of the vertical profile section 28 of each cabinet, wherein such cylindrical roller is co-axially aligned and cooperates with the respectively opposite transverse profile section 36 attached to the cabinet, and wherein such cylindrical roller is further firmly joined with a rotating pulley 86 pivotally hinged on to the shank 84 of the bracket 85 and connected with motion transmission systems that shall be described in greater detail further on.
- the cylindrical roller is so shaped as to include a double-start helical groove 87 extending all along the peripheral surface thereof.
- the hollow transverse profile section 36 is provided with two short rectilinear pins 88 and 89, which are similar to, aligned with and slightly spaced from each other, and which are fitted transversally through the wall of the same profile section and are so sized as to ensure that they keep constantly engaging the helical groove 87 of the cylindrical roller 82 regardless of the rotational position thereof.
- the transverse profile section 36 can be displaced jointly with the door 6 in the transverse direction of the cabinet by acting on the handle of the same door and, in particular, when the door 6 is shifted backwards into its closed position, the transverse profile section 36 is displaced in the same direction, too, by sliding along the cylindrical roller 82 that rotates in a corresponding direction, jointly with the related pulley 86, with the result that also the associated motion transmission system will slide in the same direction, until the free end portion of the transverse profile section 36 comes to rest against the abutment position (see Figure 21 ), in which the door 6 is closed.
- the sixth component part of the inventive door support and actuation arrangement is further comprised of a second lower horizontal-axis cylindrical roller 90 similar to and mounted in a parallel arrangement relative to the above-described roller and, as in the case of the latter, supported by two parallel and mutually spaced shanks 91 and 92 of a metal bracket 93 attached to the lower end portion of the vertical profile section 28 of each cabinet in an overturned position as compared with the afore-described bracket 85, wherein such cylindrical roller is co-axially aligned and cooperating with the respectively opposite transverse profile section 51 attached to the cabinet, and wherein such cylindrical roller is further firmly joined with a rotating pulley 94 pivotally hinged on to the shank 92 of the bracket 93 and connected with the same motion transmission system that is connected with the upper pulley 86.
- the cylindrical roller is so shaped as to include a double-start helical groove 95 extending all along the peripheral surface thereof with the same winding pattern as the helical groove 87 of the upper roller 82.
- this lower cylindrical roller 90 is engaged by two short rectilinear pins (not shown), which are fitted through the wall of the transverse profile section 51 and are so sized as to ensure that they keep constantly engaging the helical groove 95 of the cylindrical roller 90 regardless of the rotational position thereof.
- the transverse profile section 51 is displaced in the same direction by sliding along the cylindrical roller 90 that rotates in a corresponding direction, jointly with the related pulley 94, with the result that also the associated motion transmission system will move in the same direction along with the opposite pulley 86, the upper cylindrical roller 82 and the upper transverse profile section 36.
- 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.
- 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.

- Illustrated in the above-listed Figures is a support and actuation arrangement for the sliding doors of wardrobe cabinets according to a preferred embodiment of the present invention, which is made and operates in the manner as described below, and which is adapted to support and slidably actuate the cabinet doors in alternate longitudinal directions into mutually co-planar positions, wherein such doors are actuated at the same time and move from a closed position, in which the doors are close to each other and aligned with each other relative to the front plane of the wardrobe cabinet, to an opened position, in which such doors are first shifted slightly forwards and then caused to slide sideways into the desired position in a parallel relation with the front plane of the wardrobe cabinet.
- In particular, illustrated in
Figures 1 and2 there are threesimilar wardrobe cabinets 5 in a perspective front view and a perspective rear view thereof, respectively, wherein these cabinets are joined to each other in a juxtaposed arrangement. Each such cabinet is shown to incorporate the door support and -actuation arrangement according to the present invention, wherein eachsuch wardrobe cabinet 5 in the illustrated example is provided with a frontplanar door 6 provided with twoside door handles doors 6 of allcabinets 5 are shown to be shifted into their closed position, in which they are arranged so as to lie aligned with each other, thereby forming a smooth planar front face of the cabinet assembly. In addition, eachwardrobe cabinet 5 is delimited by arear wall 9 extending parallel to thedoor 6, a planartop ceiling 10, a planarlower bottom 11, and two side walls, wherein in the example illustrated inFigures 1 to 4 there can be noticed theouter side walls inner side walls Figures 3 and4 there is the same assembly of the threesimilar wardrobe cabinets 5 illustrated inFigures 1 and2 . In this case, however, one of the cabinet doors, and namely the door of the middle cabinet in the example illustrated, is shown to be shifted into a half-opened position thereof in the manner as described in greater detail further on. In this position, such door turns out as being displaced forwards relative to the other doors lying in the closed position thereof. In this condition, it is then caused to slide sideways until the desired opened position thereof is reached. Finally, when such door has eventually to be brought again into its closed position, it is caused to slide back thereinto by following the same movements in the reverse sequence thereof. - Described in detail will now be the actual arrangement for supporting and actuating the sliding door of each wardrobe cabinet in the assembly, wherein such arrangement is substantially comprised of a first component part (see
Figures 5 and 6 ) applied on to the upper side of theplanar ceiling 10 of the cabinet; a second component part (seeFigures 7 and 8 ) applied on to theplanar bottom plate 11 of the cabinet; a third component part (seeFigures 9 and10 ) applied on to the rear wall of the cabinet; a fourth component part (seeFigures 11 and12 ) applied on to theplanar ceiling 10 of the cabinet, as well; a fifth component part (seeFigures 13 to 15 ) applied on to theplanar bottom plate 11 of the cabinet, as well; and a sixth component part (seeFigures 16 to 29 ) adapted to guide and synchronize the sliding movement of each door. - The first component part is substantially formed of a metal profile section 16 (see
Figures 5 and 6 ) having the same length as eachdoor 6 and configured to include a vertical rectilinearplanar portion 17, which is fixedly secured to the upper portion of each door by means ofscrews 18 and bent inwardly, i.e. towards the interior of the cabinet, and supporting at the end portion thereof a further verticalrectilinear profile section 19 of aluminium or thermoplastic material, which is so shaped as to have alower groove 20 formed therein and extending over the whole length thereof, such first component part being further comprised of anangle metal section 21 in an elongated rectilinear shape, which has the same length as theprofile section 16 and is configured to include ahorizontal portion 22, which is secured to the front edge of theceiling 10 of the cabinet, and an upwards facing shortvertical portion 23, so as to be able to guide the alternate longitudinal sliding movement of the upper portion of thedoor 6 in the manner that shall be described in greater detail further on. In turn, the second component part is substantially comprised of anangle section 24 of metal or thermoplastic material (seeFigures 7 and 8 ), having a rectilinear horizontal extension over a same length as the length of eachdoor 6 and so shaped as to include a shorthorizontal portion 25, which is joined to the lower portion of eachdoor 6 by means ofbrackets 26, and which is bent upwards to form a shortvertical portion 27 acting as a guide, or runner, for the door to be able to perform the alternate longitudinal sliding movement thereof in the manner that shall be described in greater detail further on. - The third component part is substantially comprised of a robust vertical metal profile section 28 (see
Figures 9 and10 ) having a length that is equal to the height of the cabinet, which is secured in an intermediate position against therear wall 9 of each cabinet so as to extend all over the height of such rear wall (see alsoFigure 2 ), wherein the upper and lower end portions thereof are bent horizontally and configured in the manner and to the purposes that shall be described and explained in greater detail further on. - The fourth component part is substantially comprised of an upper skid 29 (see
Figure 11 and12 ) adapted to allow the upper portion of eachdoor 6 to perform the alternate longitudinal sliding movement thereof and substantially comprised of an elongated rectilinearmetal profile section 30 having a length that is slightly shorter than the length of eachdoor 6 and so shaped as to include a frontplanar edge 31 in which there are pivotally hinged, in a freely rotatable manner, various ratherthin wheels 32 regularly spaced from, similar to and aligned with each other, which are adapted to slide in an alternate longitudinal direction along thecorresponding groove 20 in theprofile section 19 that is secured, jointly with theprofile section 16, to the upper portion of eachdoor 6. This elongated rectilinearmetal profile section 30 is further provided with twoside wheels 33, which are similar to each other and are pivotally hinged in a freely rotatable manner at the side end portions of the same profile section in an orthogonal position relative to the above-citedwheels 32; additionally, it is also provided with twofurther wheels 34, similar and situated close to each other, that are pivotally hinged in a freely rotatable manner in the lowerplanar edge 35 of the profile section with a downward-facing orientation, wherein all these wheels are provided to the purposes that shall be described in greater detail further on. Theelongated profile section 30 of the above-described skid is further joined with a middle rectilineartransverse profile section 36 that is bent downwards so as to delimit an inner cavity opening downwards, wherein such profile section is arranged orthogonally to said elongated profile section, at the rear thereof, thereby forming a T-shaped structure, and extends over the entire depth of each cabinet; between theseprofile sections inclined profile sections transverse profile section 36 is inserted onto the corresponding bent upper end portion of thevertical profile section 28, by which it is therefore supported, and this end portion of thevertical profile section 28 is provided with an actuation mechanism that is so shaped and configured as this shall be described in greater detail further on, wherein such mechanism is adapted to cause the assembly formed by thetransverse profile section 36 and theskid 29 to displace, jointly with thedoor 6, by just a limited extent in the alternate transversal direction of each cabinet. - The
upper skid 29 is laid to rest upon and fixed with thelower edge 35 thereof to the planarhorizontal portion 22 of theangle section 21 and cannot displace from such position owing to theside wheels 33 thereof, which are resting against corresponding raisedportions 39 of such planarhorizontal portion 22 of theangle section 21, and thelower wheels 34 thereof, which engage, on both sides thereof, amiddle rib 40 provided transversally on the same planar horizontal portion of the angle section, and owing also to theupper skid 29 being laterally delimited by thevertical section portion 23 and a further shortvertical portion 41 of the afore-citedprofile section 16 formed along the other side edge of the above-cited planarhorizontal section portion 22 in a position lying parallel to saidvertical section portion 23. Theupper skid 29 is kept in this position also by means of thetransverse profile section 36 joined to the same skid, the free rear end portion of which is caused to pass through abracket 42 attached to theceiling 10 of the cabinet, by whichsuch profile section 36 is therefore supported, and in thisbracket 42 there are pivotally hinged in a freely rotatable manner and in mutually opposing positions two vertical-axisidle wheels transverse profile section 36, to the purpose of guiding the sliding movement of the profile section in the transversal direction of the cabinet, in the manner and to the purposes that shall be described in greater detail further on, as well as preventing the same profile section from displacing in the longitudinal direction of the cabinet. The longitudinal sliding movement of thedoor 6 in each cabinet occurs by placing theprofile section 16 supporting thedoor 6 in a position above and corresponding to theupper skid 29, while fitting allidle wheels 32 of such skid in thegroove 20 defined by thevertical profile section 19. In this condition, thisprofile section 19 will then be able to slide on all above-cited idle wheels in the longitudinal direction of the cabinet, wherein it will, be guided in this sliding movement thereof by a guide plane formed of a sequence of regularly spacedguide wheels 45 provided in a mutually aligned arrangement and pivotally hinged in a freely rotatable manner in thevertical portion 23 ofsuch angle section 21 in positions that are parallel to the ones of thewheels 32 of the upper skid. - In the condition in which the
door 6 of each cabinet is closed, the skid 29-transverse profile section 36 assembly is displaced rearwards in the transverse direction of the cabinet, in the position shown inFigure 38 , in which allidle wheels 32 of theupper skid 29 are engaged in thegroove 20 of thevertical profile section 19, whereas thewheels 45 of theangle section 21 are not engaged therein, so thatsuch wheels 45 solely perform as a guide plane for the longitudinal sliding movement of theprofiler section 19 and, as a result, the corresponding sliding movement of thedoor 6. In the condition in which thedoor 6 of each cabinet is open, i.e. a condition that is reached by acting on the handle of the door and pulling such door forwards, the skid 29-transverse profile section 36 assembly is displaced forwards in the transverse direction of the cabinet, jointly with thedoor 6, and shifted into the position illustrated inFigure 39 , in which thevertical profile section 19 and therelated groove 20 come to be also aligned with theidle wheels 45 of theangle section 21, so that, in this position, to be engaged in thegroove 20 of thevertical profile section 19 there are not solely thewheels 32 of theupper skid 29, but also thewheels 45 of theangle section 21, during the longitudinal sliding movement of theprofile section 19 and, as a result, thedoor 6 shifted into the opened position thereof lying over the front plane of the cabinet in front thereof. Upon having slidably displaced the door into the desired opening position in the above-described manner, the same door can be of course caused to slide back into the afore-described closed position thereof in the reverse sequence of the above-described movements. - With reference to
Figures 13-15 , the fifth component part of the door support and actuation arrangement according to a preferred embodiment of the present invention shall now be illustrated. This fifth component part is substantially comprised of alower skid 46 adapted to allow the lower portion of eachdoor 6 to perform the alternate longitudinal sliding movement thereof and substantially comprised of anelongated angle section 47 having the same length as the door and located in a position lying under the bottom 11 of the cabinet, this elongated angle section being further shaped so as to include a planarvertical portion 48 that is bent at the upper portion thereof to form a short horizontalplanar portion 49, said elongated angle section being further provided in the middle region thereof with two similaridle wheels 50 situated close to each other and pivotally hinged in a freely rotatable manner, and being joined with atransverse profile section 51 arranged orthogonally to said elongated profile section, at the rear thereof, thereby forming a T-shaped structure, and extends over the entire depth of each cabinet; as in the preceding case, between theseprofile sections inclined profile sections transverse profile section 51 is inserted onto the corresponding bent lower end portion of thevertical profile section 28, by which it is therefore supported, and this end portion of thevertical profile section 28 is provided with an actuation mechanism similar to the afore-considered upper one, as this shall anyway be described in greater detail further on, adapted to cause the assembly formed by thetransverse profile section 51 and thelower skid 46 to displace, jointly with thedoor 6, by just a limited extent in the alternate transversal direction of each cabinet, synchronously with the movement of the upper assembly formed of thetransverse profile section 36 and theupper skid 29. Against the front surface of the verticalplanar portion 48 of theangle section 47 there are secured and supported twosimilar shoes rectilinear shank 56, which is applied and appropriately secured against said front angle-section surface, as well as twoshort side shanks 57 similar to each other and projecting forwards from the same section, said side shanks being so spaced from each other as to form a free space therebetween, in which there is accommodated a relatedidle roller 58 supported by ashort arm 59 secured against theangle section 47 and provided there to the purposes that shall be described in greater detail further on In each one of saidside shanks 57 of theshoes slit 60 extending thereunder and through allsuch slits 60 of theshoes vertical portion 27 of theangle section 24, which is joined against the lower portion of thedoor 6, so that the same door is allowed to slide in the longitudinal direction through allslits 60, which therefore perform as a support and a sliding guide for the door. Onto the horizontalplanar portion 49 of thelower skid 46 there is applied anangle section 61 having the same length as said skid, wherein this angle section is so shaped as to include a horizontalplanar portion 62, having a greater width than thehorizontal portion 49 of theskid 46 thereunder, and a vertical and frontplanar portion 63, wherein thehorizontal portion 62 of theangle section 61 is provided withside flanks planar border horizontal portion 49 of thelower skid 46 lying thereunder, thereby joining theangle section 61 lying thereabove and saidskid 46 with each other. In this condition, theupper wheels 50 of thelower skid 46 come to rest against the sides of atransverse rib 68 formed in the lower surface of thehorizontal portion 62 of the angle section under the bottom 11 of the cabinet. - In turn, laterally against the rear surface of the vertical angle-section portion 63 there are applied two vertical shoes 69 and 70 similar to each other, the purpose of which shall be described in greater detail further on; each such shoe is comprised of a respective rear quadrangular plate 71 (see
Figures 35 to 37 ) attached against the vertical angle-section portion 63, as well as a front moveable quadrangular plate 72, which is arranged above the rear plate 71 and supported by the latter so as to be able to slide relative thereto by a limited extent in the vertical direction, by means of a linkage system of a kind largely known as such in the art, along corresponding vertical guides 73 provided on the same rear plate, wherein both such plates are made so as to have a width enabling them to fit into the free space defined between the side shanks 57 of the respective shoes 54 and 55, and each movable front plate 72 is so shaped over the entire width thereof to include a rear and lower front recess 74 (see alsoFigures 32 and33 ) and a thin projecting front lug 75 provided with a wall 76 slanting with an inclination rising from the bottom upwards, which is situated in a position opposite to and coincident with the position of the idle roller 58 of the respective shoe 54, 55, so as to interact with such idle roller in a manner that shall be described in greater detail further on. Eachfront plate 72 is furthermore provided with anupper receptacle 77 adapted to receive and accommodate the end portion of acorresponding compression spring 78, the other end, portion of which is accommodated in the lower surface of the horizontal angle-section portion 62, and this movable front plate is displaceable from a lowered position thereof, as illustrated inFigures 8 ,15 and33 , in which it is biased into such position by thespring 78 when thedoor 6 is shifted in the closed position thereof, to the raised position thereof shown inFigure 32 against the action of saidspring 78, which is compressed, when thedoor 6 is shifted into the opened position thereof. Thelower skid 46 is kept in the above-described position also by the effect of thetransverse profile section 51 joined to the same skid and bent upwards to delimit an inner cavity opening upwards, and the free rear end portion of suchtransverse profile section 51 is caused to pass through abracket 79, similar to and arranged symmetrically relative to the previously describedbracket 42, which is attached to both the bottom 11 of the cabinet and theprofile section 51, and pivotally hinged in a freely rotatable manner tosuch bracket 79 in mutually opposing positions there are two vertical-axisidle wheels 80 and 81 acting from both sides against the related side surface of thetransverse profile section 51, and also in this case there occurs a sliding movement of the profile section by just a limited extent in the transversal direction of the cabinet, in the manner and to the purposes that shall be described in greater detail further on, while the same profile section is prevented from displacing in the longitudinal direction of the cabinet. - With reference to
Figures 16 to 29 , the sixth component part of the door support and actuation arrangement according to the present invention shall now be illustrated in various embodiments thereof. In particular, illustrated inFigures 16 to 23 there is this sixth component part in a first embodiment thereof, wherein it can be noticed to be substantially comprised of a first upper horizontal-axiscylindrical roller 82 pivotally hinged in a rotatable manner between two parallel and mutually spacedshanks metal bracket 85 attached to the upper end portion of thevertical profile section 28 of each cabinet, wherein such cylindrical roller is co-axially aligned and cooperates with the respectively oppositetransverse profile section 36 attached to the cabinet, and wherein such cylindrical roller is further firmly joined with a rotatingpulley 86 pivotally hinged on to theshank 84 of thebracket 85 and connected with motion transmission systems that shall be described in greater detail further on. Furthermore, the cylindrical roller is so shaped as to include a double-starthelical groove 87 extending all along the peripheral surface thereof. In turn, at the free end portion thereof facing thecylindrical roller 82, the hollowtransverse profile section 36 is provided with two shortrectilinear pins helical groove 87 of thecylindrical roller 82 regardless of the rotational position thereof. As already noted hereinbefore, thetransverse profile section 36 can be displaced jointly with thedoor 6 in the transverse direction of the cabinet by acting on the handle of the same door and, in particular, when thedoor 6 is shifted backwards into its closed position, thetransverse profile section 36 is displaced in the same direction, too, by sliding along thecylindrical roller 82 that rotates in a corresponding direction, jointly with the relatedpulley 86, with the result that also the associated motion transmission system will slide in the same direction, until the free end portion of thetransverse profile section 36 comes to rest against the abutment position (seeFigure 21 ), in which thedoor 6 is closed. On the other hand, when thedoor 6 is shifted from the closed position to the opened position thereof by first displacing the same door forwards relative to the cabinet, thetransverse profile section 36 will slide along thecylindrical roller 82 in the reverse direction, and the same roller rotates, jointly with the relatedpulley 86, in the opposite direction as compared with the previous one, with the result that also the associated motion transmission system will slide in the same direction, until the free end portion of thetransverse profile section 36 comes to rest against the other abutment position (seeFigure 22 ), in which thedoor 6 is fully open. - The sixth component part of the inventive door support and actuation arrangement is further comprised of a second lower horizontal-axis
cylindrical roller 90 similar to and mounted in a parallel arrangement relative to the above-described roller and, as in the case of the latter, supported by two parallel and mutually spacedshanks metal bracket 93 attached to the lower end portion of thevertical profile section 28 of each cabinet in an overturned position as compared with the afore-describedbracket 85, wherein such cylindrical roller is co-axially aligned and cooperating with the respectively oppositetransverse profile section 51 attached to the cabinet, and wherein such cylindrical roller is further firmly joined with a rotatingpulley 94 pivotally hinged on to theshank 92 of thebracket 93 and connected with the same motion transmission system that is connected with theupper pulley 86. Furthermore, the cylindrical roller is so shaped as to include a double-starthelical groove 95 extending all along the peripheral surface thereof with the same winding pattern as thehelical groove 87 of theupper roller 82. As in the previous case, also this lowercylindrical roller 90 is engaged by two short rectilinear pins (not shown), which are fitted through the wall of thetransverse profile section 51 and are so sized as to ensure that they keep constantly engaging thehelical groove 95 of thecylindrical roller 90 regardless of the rotational position thereof. In this manner, when thedoor 6 is shifted into either of the closed or opened positions thereof by acting on the handle of the same door, also thetransverse profile section 51 is displaced in the same direction by sliding along thecylindrical roller 90 that rotates in a corresponding direction, jointly with the relatedpulley 94, with the result that also the associated motion transmission system will move in the same direction along with theopposite pulley 86, the uppercylindrical roller 82 and the uppertransverse profile section 36. In these conditions, thedoor 6 is displaced at both the lower portion thereof, by means of the lowertransverse profile section 51 and the lowercylindrical roller 90, and the upper portion thereof, by means of the uppertransverse profile section 36 and the uppercylindrical roller 82, with a synchronized movement. -
Figure 23 solely illustrates the upperrotating pulley 86 of the uppercylindrical roller 82, in therace 96 of which there are wound several turns of aflexible steel cord 97 forming the motion transmission system to and from the uppertransverse profile section 36 and the lowertransverse profile section 51, said flexible steel cord being also wound in the same manner round theother pulley 94 of the lowercylindrical 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. In this case, the motion transmission system is comprised of acog belt 98 wound round a corresponding rotating cog-pulley 99 co-axially coupled to the uppercylindrical roller 82, and such cog belt is also wound round the other rotating cog-pulley (not shown) that is co-axially coupled to the lowercylindrical roller 90. Shown inFigure 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 metalperforated strap 100 wound round a corresponding rotating cog-pulley 101 co-axially coupled to the uppercylindrical roller 82, and such perforated strap is also wound round the other rotating cog-pulley (not shown) that is co-axially coupled to the lowercylindrical roller 90. 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 inFigures 26 to 31 , wherein such motion transmission system is in this case comprised again of aflexible steel cord 97, which is wound round theraces 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 thevertical profile section 28 of each cabinet (seeFigures 27 and 28 ), and said flexible steel cord is also wound round therace 104 of a vertical-axis deviation pulley 105 that is rotatably hinged on to asupport bracket 106 attached to said upper end portion of thevertical profile section 28 and a securingbolt 107 that is inserted transversally in theprofile section 36. Furthermore, thesteel cord 97 is also wound round theraces 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 (seeFigure 29 ), and also in this case said flexible steel cord is wound round therace 110 of a vertical-axis deviation pulley 111 that is rotatably hinged on to asupport bracket 112 attached to said lower end portion of thevertical profile section 28, and the securingbolt 107 is inserted transversally in thetransverse profile section 51.Figures 30 and 31 illustrate this motion transmission system using suchflexible steel cord 97, as installed on the upper portion of the wardrobe cabinet. It can be noticed that theflexible 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 thebracket 106, and is secured with therelated bolt 107 in the transverse direction of theupper profile section 36. so that thisprofile section 36 can still be displaced, in the afore-described manner, from the closed position of thedoor 6 inFigure 30 to the opened position of the same door inFigure 31 , and vice-versa. It can on the other hand be most readily appreciated that the motion transmission system used as a motion transmission means to and from said upper and lowertransverse profile sections - Illustrated in greater detail in
Figure 34 are the two different construction members making up the structure of themetal 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 toFigures 5 and 6 and, for the matter, substantially comprised of both saidprofile section 16, as shaped in the afore-described manner and attached to the upper portion of thedoor 6, and a rectilinearvertical profile section 19 secured to saidprofile section 16 and provided with alower groove 20 for the door to slide therein, as well as anangle section 21 attached to theceiling 10 of the cabinet. As can be seen in this Figure, theprofile 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 thefront wheels 45 rotatably hinged on to theangle section 21 to be received and accommodated there in the closed condition of the door (seeFigure 38 ), as well as enabling also thefront wheels 32 of theupper skid 29 to be received and accommodated there in the opened condition of the door (seeFigures 39 to 41 ), in which saidwheels 32 move into an arrangement in which they are longitudinally aligned with thewheels 45. In turn, the rectilinearvertical profile section 19 is so shaped all along the longitudinal extension thereof as to include anupper recess 115 that is fitted into the rectilinearbent border 116 of theprofile section 16, thereby securing these profile sections to each other, and is further so shaped as to include the afore-described lower slit orgroove 20, as well as a sequence ofsemi-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 thewheels 45, so as to be able to fit onto the correspondingfront wheels 45 of theprofile 16 in the closed position of thedoor 6. - Finally, illustrated in
Figures 32 to 37 is the lower portion of thedoor 6 and the manner in which it is shifted from its closed position (seeFigure 33 ), on the front side of the wardrobe cabinet, and into its opened position (seeFigure 32 ). As can be seen in the illustration ofFigure 33 , where thedoor 6 is shown to be shifted in the closed position thereof, theangle section 24, which is secured to the lower portion of thedoor 6 by means ofbrackets 26, engages with thevertical portion 27 thereof theslits 60 in theshoes angle section 47, to thereby be firmly retained there without being able to displace. In this condition, themiddle roller 58 of each skid lies aligned with and spaced from the projectinglug 75 and the slantingwall 76 of the respective movablefront plate 72 of thevertical shoes angle section 61 attached to thelower skid 46, and suchmovable plate 72 is kept in its lowered resting position by thespring 78. When thedoor 6 is then shifted from the closed position into the opened position thereof, with a forward movement on the front side of the wardrobe cabinet, also the assembly comprised of theshoes middle roller 58 is at the same time displaced forwards gradually by the action of theangle section 24 engaging the same shoes, whereas theangle section 61 and the movablefront plate assembly 72 keep at rest, i.e. do not move. In this manner, themiddle roller 58 moves gradually closer to the projectinglug 75 and the related slantingwall 76 and, as soon as it comes to abut against the slantingwall 76, it starts sliding thereupon, so that, as theroller 58 keeps in this way sliding forwards, it causes the projectinglug 75 to gradually rise jointly with the relatedmovable plate 72, which in turn causes thespring 78 to become gradually compressed, thereby clearing the rectilinear sliding path of thebrackets 26 and theangle section 24. When thedoor 6 reaches into its opening position, in which it is fully displaced forwards (seeFigure 32 ), themovable plate 71 of thevertical shoes roller 58, so that theangle section 24 is able to freely move into the end-of-travel or abutment position thereof, in which itsvertical portion 27 fits into thelower recess 74 of the relatedmovable plate 71. In this condition, the opened door can be caused to slide sideways into the desired position, thanks to thevertical portion 27 of theangle section 24 being thus able to slide on thevertical shoes slits 60 in theshanks 57. - For the door to be then brought back into the closing position thereof, all it takes is pushing the same door towards the interior of the cabinet until it reaches such position, wherein all above-cited mechanic members will displace in the reverse order of the moving sequence.
- In the modified embodiment of the door support and actuation arrangement which does not form part of the present invention and illustrated in Figures 42 to 45, there have been omitted the metal
vertical profile section 28 of the third component part, as well as Themotion transmission members vertical profile section 28 and the upper and lowertransverse profile sections door 6. In this manner, the displacements of eachdoor 6 being actuated into closing or opening occur in this case with different movements that are no longer synchronized with each other. When each door is displaced in the closed position thereof, as shown in Figure 42, 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. the upper side in this case (see Figure 44), outwardly until the related abutment is reached, under a corresponding inclination of the door, so that, as soon as these movements are completed, the door turns out as being displaced frontwards in a parallel arrangement relative to the remaining doors of the wardrobe, in a condition in which it is ready for being shifted sideways. - Shown in Figure 45 there is finally the
door 6 in the condition in which it is fully shifted sideways, i.e. to the right side in this case, so that the inner cavity of the wardrobe cabinet is accessible. Shifting the door into its closed position is done through a reverse sequence of the above-described movements, wherein the door is first caused to slide into its closing position, in which it is displaced frontwards in front of the inner cavity of the cabinet, and then pushing inwardly first a side and then the other side of the door until the respective abutments are reached, thereby bringing the door back into the fully closed position thereof shown in Figure 42. Displacing the door into opening or closing through the sequence of the above-described movements can occur by initially displacing either of the lower or upper portions thereof and then displacing the remaining one.
