Definitions

  • the present invention relates to the field of mechanisms for displacing the doors of items of furniture, such as cupboards, shelves or the like.
  • the present invention relates to a mechanism for displacing two coplanar doors of a piece of furniture.
  • the invention also relates to a piece of furniture comprising a mechanism for the displacement of its doors according to the present invention.
  • the mechanism in this solution comprises a pair of lower guides and a pair of upper guides connected respectively to the floor and ceiling of the space inside a piece of furniture that is closed/opened by means of doors.
  • the mechanism also comprises brackets sliding on said guides with suitable sliding means.
  • the above-described pairs of guides each comprise a first straight front guide and a second rear guide consisting of a straight section, parallel to the front guide, terminating with a curved end diverging from the front guide.
  • the mechanism also comprises transversal guide elements that serve the purpose of displacing the connection brackets transversally as the brackets slide along the guides.
  • the main aim of the present invention is therefore to produce a mechanism for the displacement of coplanar doors that enables the drawbacks of the known art to be overcome.
  • one object of the present invention is to produce a displacement mechanism that consists of a limited number of components that are easy to assemble.
  • Another object is to produce a displacement mechanism that is reliable in use and easy to manufacture at competitive costs.
  • the mechanism according to the present invention comprises a first and a second displacement shoe operatively connected respectively to a first door and to a second door of a piece of furniture.
  • At least one, and preferably both of said shoes comprise a main carriage with at least a first axle and a second axle rigidly connected to a frame.
  • Said main carriage comprises a plurality of wheels that enable its displacement along a first guide and a second guide designed to be connected to a connection surface of a piece of furniture.
  • Said at least one displacement shoe comprises an attachment bracket designed to be connected to a corresponding one on said doors.
  • Said bracket is connected to the first axle and to the second axle of the main carriage by means of a first and a second slider, respectively, which enable a translation and a rotation of the bracket with respect to the main carriage.
  • the displacement mechanism also comprises guide means operatively connected to said bracket to determine said translation and said rotation during the displacement of the main carriage.
  • the movement of the attachment bracket, and therefore of the door connected thereto is determined by the combination of the movements of the main carriage along the longitudinal guides, and by the movement of the attachment bracket with respect to said carriage (a movement permitted by the two sliders and governed by the guide means operatively connected to the bracket).
  • the mechanism according to the invention achieves the displacement of the doors by means of a rather limited number of components, with obvious advantages in terms of its reliability in use and final manufacturing costs.
  • the attachment bracket guide means comprise a guide element located between the two longitudinal displacement guides and comprising a first and a second shaped grooves.
  • the guide means may comprise a first and a second guide roller respectively connected to the first and second sliders of the attachment bracket. The first guide roller is inserted pivotally in the first guide groove, while the second guide roller is inserted pivotally in the second groove.
  • the interaction between the guide rollers and the corresponding grooves in which they can slide determines the movement of the attachment bracket with respect to the main carriage.
  • the movement of the bracket is then translated into the movement of the door attached thereto.
  • the displacement mechanism may comprise elastic means operatively interposed between the main carriage and the attachment bracket so as to exert a contrasting force that opposes the displacement of the bracket with respect to the carriage.
  • the present invention also relates to a piece of furniture with coplanar doors, this term being intended to mean any article of civil or industrial furniture normally used in the domestic or working environment.
  • the piece of furniture according to the invention comprises a structure defining a containment space accessible through an opening that can be closed or opened by means of at least a first and a second door.
  • the piece of furniture comprises at least one displacement mechanism according to the present invention for moving said doors from a closed configuration to an open configuration.
  • the displacement mechanism according to the invention can be fixed to a connection surface of the piece of furniture coinciding, for instance, with the portion that serves as the ceiling of its interior.
  • the piece of furniture advantageously comprises a further displacement mechanism according to the invention fixed to a connection surface defined by the floor of said interior. In both cases, the mechanism enables the stable displacement of both of the doors by means of the attachment brackets of the two shoes connected on the same side to the corresponding doors.
  • each displacement shoe 10,20 comprises a main carriage 11, which is defined by a frame with at least a first axle 11A (hereinafter also called the "front axle” 11A) and at least a second axle 11B (hereinafter also called the "rear axle 11B", or "first rear axle 11B"), which are parallel to one another.
  • the carriage 11 also comprises a pair of longitudinal sides 13A, 13B, that rigidly connect the two axles 11A, 11B.
  • the main carriage 11 also comprises a plurality of wheels, which enable its displacement.
  • the carriage 11 preferably comprises at least one pair of front wheels 31 and at least one pair of rear wheels 32 that enable its displacement in a longitudinal direction 101 defined by a first guide 5A and a second guide 5B, which are parallel to one another and connectable to a connection surface 300 of a piece of furniture.
  • Said connection surface 300 may coincide, for instance, with the ceiling or top of a space inside a piece of furniture designed to be opened/closed by means of said doors.
  • the connection surface 300 may also be the floor of a piece of furniture, or of any other space that can be closed by means of said doors.
  • the two guides 5A,5B thus define a longitudinal translation direction 101 for the carriage 11 (see figure 4 , for instance).
  • the two guides 5A,5B define a plane of displacement or translation for the main carriage 11.
  • the two axles 11A,11B extend in a direction 102 (hereinafter also indicated as the "transversal direction 102") orthogonal to the longitudinal direction 101.
  • Each of the two shoes 10,20 comprises an attachment bracket 40 designed to be connected to one of the doors 201,202 to displace. More precisely, the bracket 40 of the first shoe 10 can be connected to a first door 201 of the piece od furniture, while the attachment bracket 40 of the second shoe 20 can be connected to a second door 202 (see figures 2 and 3 , for instance). Conventional screw fixing means may advantageously be used for said connection, or other functionally equivalent means.
  • the attachment bracket 40 is connected operatively to the main carriage 11 by means of a first slider 51 and a second slider 52 designed to translate and rotate the bracket 40 with respect to the carriage 11. More precisely, the two sliders 51,52 enable a translation of the bracket 40 in the transversal direction 102 (see figure 2 ) parallel to the axes 103,103A of the axles 11A,11B. At the same time, the two sliders 51,52 enable a rotation of the bracket 40 with respect to the carriage 11 around an axis substantially orthogonal to the plane of displacement of the carriage 11, said plane being defined by the guides 5A.5B. In practice, according to the invention, the attachment bracket 40 can rotate and translate with respect to the main carriage 11 by means of the two sliders 51,52. The latter substantially represent the kinematic interface between the attachment bracket 40 and the main carriage 11.
  • the displacement mechanism 1,1A,1B comprises guide means 9,81,82 that act on the attachment bracket 40 to induce its translation and rotation during the displacement of the main carriage 11 in the longitudinal direction 101.
  • the guide means comprise a guide element 9 located operatively between the first guide 5A and the second guide 5B (see figure 18 , for instance).
  • the guide element 9 comprises a first shaped groove 61 and a second shaped groove 62, each with a guide roller 81,82 inserted therein and connected to one of the two sliders 51,52. More precisely, a first guide roller 81 is connected to the first slider 51 and pivotally inserted in the second groove 62, while a second guide roller 82 is connected to the second slider 52 and pivotally inserted in the first groove 61.
  • the position occupied by the guide rollers 81,82 inside the corresponding grooves 61,62 determines the position of the attachment bracket 40 with respect to the corresponding main carriage 11.
  • the interaction between the rollers 81,82 and the corresponding grooves 61,62 by means of the two sliders 51,52, determines a rotation-translation of the attachment bracket 40 with respect to the main carriage 11 during the longitudinal displacement of the carriage in the longitudinal direction 101.
  • the combination of the longitudinal displacement of the main carriage 11 with the rotation-translation of the attachment bracket 40 determines the displacement of the door 201,202 connected to said bracket.
  • Figures 1 to 3 are perspective views relating to a first possible embodiment of a displacement mechanism according to the invention indicated by the numerical reference 1.
  • Each of these figures shows the mechanism 1 in a particular operative configuration.
  • figure 1 shows the mechanism 1 in a configuration according to which the two doors 201,202 are coplanar so that, in practice, they close the space inside the piece of furniture on which they are fitted.
  • Figure 2 shows the mechanism 1 during a first displacement phase in which the second door 202 is tilted with respect to the first door 201.
  • Figure 3 shows the mechanism 1 in a second displacement phase, subsequent to the first, in which the second door 202 moves parallel to the first door 201.
  • the two doors 201,202 are arranged on parallel planes so that the second door 202 can translate until it faces the first door 201. In this way, the part of the space in the piece of furniture previously closed by the second door 202 is thus opened.
  • Figures 4 and 7 are views from above relating to the configuration of the mechanism 1 shown in figure 1
  • Figures 5 and 8 are views from above relating to the configuration in figure 2
  • figures 6 and 9 are views from above relating to the configuration of the mechanism 1 in figure 3
  • figures 7 to 9 show the shape of the main guide body 9, i.e. the shape of the grooves 61,62 in which the guide rollers 81,82 connected to the two sliders 51,52 connected to the attachment bracket 40.
  • the first groove 61 has a central portion 61A substantially parallel to the longitudinal direction 101 and two shaped terminal portions 61 B that are symmetrical with respect to the central portion 61A.
  • the second groove 62 also has a straight central portion 62A parallel to that of the first groove 61A and two shaped terminal portions 62B symmetrical with respect to the central portion 62A.
  • the shape and length of the shaped terminal portions 61 B of the first groove 61 and of the shaped portions 62B of the second groove 62 are designed so that, following the displacement of the main carriage 11, the two rollers 81,82, by means of the corresponding sliders 51,52, determine the extent and duration of the rotation-translation of the attachment bracket 40 with respect to the main carriage 11.
  • the lengths of the central portion 61A of the first groove 61 and of the central portion 62A of the second groove 62 are defined so as to enable the second door 202 to translate, after completing the rotation-translation phase, until it overlaps with the first door 201.
  • the rotation-translation of the bracket 40 comes to an end when the guide rollers 81,82 reach the central portions 61A,62A of the two grooves 61,62, which are parallel to one another. In this condition ( figures 6 and 9 ), the subsequent longitudinal displacement of the main carriage 11 determines an overlapping of the second door 202 over the first door 201. In fact, when the guide rollers 81,82 move in the central portions 61A,62A, the attachment bracket 40 maintains a fixed position with respect to the main carriage 11.
  • the mechanism 1 has a symmetrical structure with respect to an axis of symmetry X parallel to the transversal direction 102 and orthogonal to the longitudinal direction 101.
  • the two shoes 10,20 are structurally and functionally equivalent, being operatively symmetrical with respect to said axis of symmetry.
  • Figures 10 and 12 are a view from above and a perspective view, respectively, of the second shoe 20 in the operative configuration of the mechanism also shown in figures 1 , 4 and 7 .
  • Figures 13 and 14 are perspective views of the second shoe 20 in the operative configuration of the mechanism 1 shown in figures 2 , 5 , 8 and in figures 3 , 6 , 9 , respectively. From a comparison between figure 13 and figure 12 , it is clear that, when the displacement of the second shoe 20 begins, the range of transversal movement (i.e. the displacement in the direction 102) of the second slider 52 is greater than that of the first slider 51.
  • Figures from 15 to 17 are views from different observation points of a main carriage 11 of a displacement shoe 10,20.
  • the carriage 11 preferably has two pairs of front wheels 31,31A, two pairs of rear wheels 32,32B, and two pairs of intermediate wheels 33,33A located in a position midway between the front wheels 31,31A and the rear wheels 32,32A.
  • These wheels (front, rear and intermediate) are preferably of the "grooved" type.
  • the first guide 5A and the second guide 5B are in the shape of rails or tracks with a rounded cross-section (see figure 18 ) corresponding to the shape of the groove in the wheels 31,32 so that they are able to roll.
  • grooved wheels advantageously avoids any disengagement of the wheels 31,32, or loss of contact between said wheels and the guides/rails 5A,5B. It has been seen, moreover, that the number and position of the above-described wheels (front, rear, intermediate) advantageously enables the carriage to discharge the weight of the corresponding door 201,202 more evenly on the longitudinal guides 5A,5B. This aspect increases the versatility in use of the mechanism 1 in that it can be employed to move doors 201,202 with a broad range of weights.
  • the main carriage 11 preferably comprises a further axle 11C (hereinafter also called the "second rear axle 11C") in a position proximal to the first rear axle 11B. More precisely, the second rear axle 11C extends along an axis 103B parallel to the axis 103 of the front axle 11A and to the axis 103A of the first rear axle 11 B.
  • the above-described axles 11A,11B and 11C preferably have a substantially cylindrical shape and advantageously have a cross-section of the same diameter so that they can be made starting from the same cylindrical bar, for instance.
  • the main carriage 11 comprises two cross members 16A,16B that extend parallel to the first 11A, second 11B and third axle 11C.
  • Said cross members 16A,16B in the form of a pin for instance, connect the two longitudinal sides of the frame 13A,13B and, at the same time, they provide a seat for a helical spring 98A,98B, the purpose of which is described in detail later on.
  • FIG. 17 shows another particular feature of the main carriage 11, according to which the front wheels 31,31A, rear wheels 32,32A and intermediate wheels 33,33A are pivotally attached to the longitudinal sides 13A,13B of the frame so that the corresponding rotation axis T1 comes to be lower than the plane identified by the axes 103,103A,103B of the axles 11A,11B with respect to a reference plane R defined by the guides/rails 5A,5B on which the wheels of the carriage 11 rest. Thanks to this solution, the frame of the carriage 11 is relatively high with respect to the reference plane R affording the advantage of containing the height of the guides/rails 5A,5B.
  • Figure 18 is a side view of the displacement mechanism 1 in the configuration shown in figure 1 .
  • the mechanism 1 comprises a profiled body 5 that has a resting surface 55 designed to rest on a connection surface 300 of a piece of furniture, such as the portion forming the ceiling of the piece of furniture concerned, also called the top of the piece of furniture.
  • the first guide 5A and the second guide 5B extend from a surface opposite to the resting surface 55 and from mutually opposite sides of a seat in which the guide element 9 is contained.
  • Said seat is defined by a flat surface 55B opposite to the resting surface 55, delimited laterally by two opposite longitudinal lateral containment surfaces 57.
  • a pair of portions of the containment edge 58 extend in a position opposite to the flat surface 55B, each extending from one of the lateral containment surfaces 57.
  • the structure of this seat enables the guide element 9 to maintain its operative position unchanged with respect to the profiled body 5, which is to the advantage of the reliability of operation of the mechanism 1.
  • the guide element 9 could be an integral part of the profiled body 5.
  • the profiled body 5 comprises a first longitudinal side 41 from which a first edge 41A extends that faces towards the resting surface 55. Said first edge 41A defines a third guide 5C, which extends in a position parallel and opposite to the first guide 5A.
  • the profiled body 5 also comprises a second longitudinal side 42, opposite to the first side 41, from which a second edge 42A extends that defines a fourth guide 5D parallel and opposite to the second guide 5B.
  • the profiled body 5 comprises a first pair of opposite guides/rails (the first 5A and the third 5C) that guide the wheels keyed to a longitudinal side 13A of the carriage 11 and a second pair of guides/rails (the second 5B and the fourth 5D) that guide the wheels of the carriage 11 keyed to the other longitudinal side 13B.
  • This solution further improves the operative stability of the main carriage 11 and ensures a better distribution and absorption of the loads to which said carriage is submitted.
  • the first slider 51 of the mechanism 1 is coupled to the first axle 11A so as to be slidable in a transversal direction 102 orthogonal to the direction in which the carriage 11 moves.
  • the first slider 51 is coupled to the first axle 11A so as that it can rotate around a rotation axis orthogonal to the longitudinal direction 101 and to the transversal direction 102.
  • the first slider 51 can rotate around an axis orthogonal to the plane of translation of the carriage 11.
  • the second slider 52 of the mechanism 1 is coupled to the second axle 11 B, and preferably also to the third axle 11C, so as to be slidable in the transversal direction 102 orthogonal to the longitudinal direction 101.
  • the second slider 52 has only one degree of freedom of movement along the two rear axles 11B,11C.
  • the attachment bracket 40 is integrally connected to the first slider 51 so as to strictly follow its movements, while it is connected to the second slider 52 so as to rotate with respect to the latter around a rotation axis 500 (see figure 21 ) orthogonal to the longitudinal direction 101 and to the transversal direction 102.
  • the attachment bracket 40 is connected to the second slider 52 by means of a turning kinematic coupling that defines said rotation axis 500.
  • Figures from 19 to 22 are views of the attachment bracket 40 connected to the two sliders 51,52 of the mechanism 1, while Figure 11 is another view from above of the second shoe 20, showing in more detail the structure of the various components.
  • the attachment bracket 40 comprises a main body 40B with a first terminal part 141 connected rigidly to the first slider 51 and a second terminal part 142 connected pivotally to the second slider 52.
  • the first slider 51 consists of a first portion 51A and a portion 51B, with the first terminal part 141 of the attachment bracket 40 in between (see also figure 18 ).
  • the first slider 51 comprises a first 91 and a second swivel bush 92, respectively inserted in the first portion 51A and in the second portion 51 B (see figure 11 ).
  • the two swivel bushes 91,92 comprise an external portion 91A that is integral with the corresponding portion 51A,51B of the first slider 51 and an internal portion 91B coupled to the external portion 91A by means of a substantially spherical coupling surface (see figure 19 ).
  • the corresponding internal portion 91B is slidable along the first axle 11A in the transversal direction 102 defined by the axis 103A of said axle.
  • the internal portion 91 B is also coupled with clearance to the first axle 11A so that it also retains a degree of freedom of translation in the longitudinal direction 101 (orthogonal to the direction 102).
  • the two swivel bushes 91,92 substantially define a pair of ball joints that afford a freedom of rotation for the first slider 51 (and consequently for the attachment bracket 40) with respect to the main carriage 11 (see figure 11 ).
  • the second slider 52 comprises a sliding body 52A slidably coupled to the second axle 11B and to the third axle 11C by means of a pair of bushings 53A,53B, preferably with recirculating ball bearings. More precisely, a first ball bushing 53A couples the sliding body 52A to the second axle 11B, while a second ball bushing 53B couples the sliding body 52A to the third axle 11C.
  • the coupling of the body 52A to both the rear axles 11B,11C enables the second slider 52 to slide stably in the transversal direction 102.
  • the use of the bushings 53A,53B facilitates the kinematic coupling between the parts to the advantage of the reliability and working life of the mechanism.
  • the second slider 52 is coupled to the second terminal part 142B of the body 40B of the bracket 40 by means of a kinematic coupling that defines a rotation axis 500 for said bracket 40 (see figure 21 ).
