Definitions

  • the present invention belongs to the field of manufacturing mechanical mechanisms for the furniture industry.
  • the present invention relates to a unit for moving a sliding door of a piece of furniture, which may for example be a wardrobe.
  • the present invention further relates to an assembly for moving a sliding door of a piece of furniture comprising at least one movement unit according to the present invention.
  • a movement unit (commonly also referred to as a “sliding runner” or “movement runner”) comprises at least one support bracket connected to the door to be moved and at least one wheel which can slide along a guide connected to a portion of the piece of furniture.
  • a movement unit normally comprises a wheel-carrying element, operatively interposed between the wheel and the support bracket. This element has the purpose of defining the axis of rotation of the wheel and simultaneously bearing the support bracket.
  • a movement assembly which comprises two specific units.
  • a first movement unit has the purpose of moving the outer door with respect to the piece of furniture, and moves along a first guide connected to the roof of the wardrobe.
  • a second unit has the purpose of moving the inner door, and moves along a second guide parallel to the first and connected to the roof of the piece of furniture in a position further out than the position of the first guide.
  • a wardrobe having three doors comprises two coplanar doors and a door in a position further out.
  • the relevant movement assembly provides three movement units, two of which slide on an inner guide so as to move a corresponding side door. Meanwhile, the third movement unit slides on an outer guide to move the central door.
  • movement units to comprise an adjustment mechanism which makes it possible to adjust the position of the bracket with respect to the corresponding slide guide or the position of the door associated with the bracket with respect to the wardrobe. This adjustment is necessary so as to regain the perpendicular positioning of the doors with respect to the base of the wardrobe. Without the perpendicular positioning, on the one hand the doors themselves will slide poorly, and on the other hand, the doors will not be mutually parallel, meaning that one door ends up at an inclination to the other.
  • the perpendicular positioning may be lost, for example, as a result of incorrect assembly of the wardrobe, of said wardrobe resting on a floor which is not perfectly flat, or else of defects in size or shape which occur during the production of the various parts forming the wardrobe and/or during the assembly of said wardrobe.
  • Known adjustment mechanisms make it possible to vary the position of the bracket, and thus of the door associated therewith, with respect to the axis of the wheel, while said wheel is still borne stably on the slide guide.
  • These mechanisms comprise at least one activation element which can be accessed by an operator using a suitable adjustment tool which may for example be a key or a screwdriver. The movement of this adjustment element by the operator results in the adjustment mechanism being activated or in the entire bracket/door being displaced with respect to the wheel.
  • patent applications FR 2840038 and GB 2309477 disclose movement devices with what is known as "side" adjustment, in which, more specifically, the adjustment element is reached from one side by the support bracket in an access direction substantially parallel to the movement direction defined by the slide guide.
  • the adjustment mechanism for the position of the bracket comprises a movement rod, provided with rounded ends, which is interposed between the wheel-carrying element and the bracket in such a way that the ends are housed in corresponding cavities defining the rotation seats for said ends.
  • the adjustment mechanism comprises a screw which is activated at a side wall of the bracket and the head of which ends up abutting on a surface of the wheel-carrying element.
  • the aforementioned rod is interposed in an inclined position in such a way that an action carried out on the screw by an operator results in a rotation of the rod that is a lifting of the bracket with respect to the wheel-carrying element.
  • the activation element for the adjustment mechanism is a screw which is fixed with respect to the rod and which can be screwed to the wheel-carrying body.
  • the adjustment is brought about by way of a sliding coupling between a pin, which is rigidly fixed to the bracket and which can slide inside inclined grooves defined on the side walls of the wheel- carrying body.
  • An action carried out on the screws results in a lifting of the bracket with respect to the wheel-carrying body by virtue of the grooved guides which guide the displacement of the bracket.
  • the need to have two external units of different constructions requires a greater degree of attention from the operators not only during the step of installing the movement unit but also during any maintenance operations.
  • the need for two movement units of different constructions has a major negative impact on the manufacturing costs.
  • the position of the bracket/door assembly is adjusted by way of an activation element substantially from above with respect to a front view of the door. This adjustment is carried out using an adjustment tool (key or screwdriver) which is brought towards the activation element by way of a vertical downward movement from a position above the bracket to be adjusted.
  • this adjustment requires a difference in height of 30-40 centimetres between the roof of the wardrobe and the ceiling of the room in which said wardrobe is placed. Specifically, this difference in height is necessary to make it possible for the operator to intervene effectively and rapidly from above. Consequently, adjustment from above is a valid alternative to side adjustment only for wardrobes of limited height, whilst it is not in fact applicable in cases where the doors extend up to a height of a few centimetres less than the ceiling height. It can be seen that this aspect is particularly critical in so far as the requirement for wardrobes/pieces of furniture with particularly high doors is constantly growing, both because of their aesthetic quality and because of the larger containing volume they offer.
  • the primary goal of the present invention is to provide a new movement unit for a sliding door of a piece of furniture which makes it possible to overcome the aforementioned drawbacks.
  • a first object of the present invention is to provide a movement device unit which makes is possible to overcome the above-described drawbacks associated with "side" adjustment and adjustment "from above”.
  • a further object of the present invention is to provide a movement unit which can be used effectively for any installation requirement.

  • central body which is slidably inserted into the housing seat defined by said bracket, said central body comprising a pair of side walls which bear a wheel which can slide in a movement direction orthogonal to the axis of rotation thereof;
  • the movement unit according to the invention is characterised in that the activation means comprise at least one fixed or movable activation element, which rotates about a reference axis substantially parallel to the axis of rotation of the wheel; according to the invention, the bracket comprises an access opening formed in a position aligned with the reference axis; said opening defines a passage for an adjustment tool which can contact said activation element when said element is fixed in position with respect to the axis of the wheel; alternatively, said passage defines a passage for operatively positioning said activation element when said activation element is movable.
  • the particular orientation assigned to the reference axis of the activation element and the presence of the opening defined by way of the bracket which are provided by the present invention actually make it possible to implement substantially "frontal" adjustment, or adjustment in an intervention direction substantially parallel to the axis of rotation of the wheel or orthogonal to the plane in which the door is formed.
  • an operator can advantageously insert an adjustment tool through the opening defined on the door so as to contact the activation element, to induce a rotation therein which is transformed, by way of the adjustment mechanism, into a change in the position of the bracket.

  • the transverse portion 9 preferably also comprises a pair of side portions 9", arranged on opposite sides with respect to the central portion 9' and having a rounded shape.
  • Said side portions 9" have the purpose of stiffening the connection between the side walls 8', 8" or strengthening the structure of the central body 8.
  • the central body 8 is inserted into the seat 17 in such a way that the side portions 9" are constantly resting on the inner side 14B of the connection portion 14 of the bracket 12.
  • the central body 8 is free to slide with respect to the seat 17 in a direction parallel to the movement direction 100 of the wheel 5.
  • the constant bearing of the bracket 12 on the central body 8 is a highly advantageous situation in mechanical terms, since the central body 8 makes a decisive contribution towards bearing the weight of the door 51. This leads to improved stability of the mechanism and at the same time to an improved resistance to the bending stresses brought about by the weight of the door 51.
  • the mechanism for adjusting the movement unit V comprises means for guiding the movement of the bracket 12.
  • Said means comprise first guide means, which guide the relative displacement of the central body 8 with respect to the wheel 5 in a first displacement direction 105 inclined with respect to the movement direction 100. More specifically, said first direction 105 is inclined at an angle a of less than 90 degrees. Said angle is shown in the reference system set out to the right of Fig. 4.
  • the first guide means preferably comprise a first pair of rectilinear, parallel grooves 18, 18" (also referred to in the following as “first grooves 18', 18"), each of which is defined on a corresponding side wall 8', 8" of the central body 8. Said grooves 18', 18" are passed through by opposite portions of a connecting pin 16, which defines the axis of rotation 101 of the wheel. As a result of the first grooves 18', 18", the central body 8 is thus constrained to move in the first displacement direction 105 with respect to the axis of rotation 101 of the wheel 5, which forms a fixed reference during the adjustment of the position of the bracket 12, i.e. of the door associated therewith.
  • the guide means of the adjustment mechanism preferably also comprise second guide means which guide the relative displacement of the bracket 12 with respect to the wheel 5 along a second displacement direction 106 substantially orthogonal to the movement direction 100 of the device 1 .
  • the second displacement direction 106 substantially corresponds to a vertical displacement direction, i.e. parallel to the plane in which the door 51 is formed.
  • said second guide means preferably comprise a pair of mutually parallel, rectilinear grooves 19', 19" (also referred to in the following as "second grooves 19', 19"), each defined on a corresponding one of the bearing portions 13', 13" of the bracket 12 which define the housing seat 17 of the central body 8.
  • the exploded view of Fig. 4 and the sectional view of Fig. 9 make it possible to see the position provided by the second grooves 19', 19".
  • the connecting pin 16 comprises opposite ends 16', 6" which pass through the two grooves 19', 19" defined on the bearing portions 13, 13" of the bracket 12 so as to create a sliding coupling between said bracket 12 and the axis of the wheel 5. Therefore, in view of what is disclosed above, it is clear that the central body 8 and the bracket 12 are both kinematicaiiy coupled to the connecting pin 16 of the wheel 5, by way of the above-defined first grooves 18', 18" and second grooves 19', 19" respectively.
  • the activation means of the adjustment mechanism preferably comprise a rack 25, associated with the central body 8, and a pinion element which forms the activation element 26 of the mechanism.
  • the rack 25 is defined on the transverse portion 9 of the central body 8, more specifically at the central part 9' thereof.
  • the activation element 26 of the mechanism is defined by a pinion element which engages in the rack 25 so as to rotate about an axis of rotation (coincident with the reference axis of rotation 102) and parallel to the axis of rotation 101 of the wheel 5, as can clearly be seen for example from the side view of Fig. 3.
  • the activation element 26 will also be referred to as the "pinion 26".
  • the rotation of the pinion 26 about the reference axis 102 brings about relative sliding of the central body 8, with which the rack 25 is associated, in the movement direction 100. This sliding takes place with respect to the bracket 12, which preferably remains resting on said central body 8.
  • the pinion 26 and the rack 25 have to be shaped so as to engage in one another or in such a way that a rotation of the pinion 26 effectively corresponds to a sliding of the central body 8.
  • the pinion 26 has a formation of straight teeth
  • the rack 25 is defined by a plurality of straight, mutually parallel grooves defined on the transverse portion 9 of the central body 8. Said grooves are orientated in a direction parallel to the axis of rotation (reference axis 102) of the pinion 26 or parallel to the axis of rotation 101 of the wheel 5.
  • the pinion 26 is preferably rigidly fixed to the bracket 12 so as to be rotatable about the axis of rotation (102) thereof.
  • the pinion 26 is preferably housed in a cylindrical seat 24 defined by the second bearing portion 13" of the bracket 12 so as to engage in the rack 25 of the central body 8 above said rack.
  • the reference axis 102 of the pinion 26 is located, with respect to the axis of rotation 101 of the wheel 5, at a height greater than the height at which the central part 9' of the transverse portion 9 of the central body 8 is located.
  • the pinion element 26 comprises an end 26' (shown for example in Fig. 8 and 10) which faces the anchoring portion 12' or the access opening 46 defined by the bracket 12 above the edge 51 ' of the door 51. Said end 26' can be contacted by an adjustment tool 300, which may be a screwdriver or an Allen key, which can be inserted at the front through the opening 46 by an operator in accordance with the principles stated above. It is noted that said opening 46, aside from making the end 26' accessible, defines an advantageous reference for inserting the adjustment tool 300 and thus for easily and rapidly contacting the end 26' of the pinion 26.
  • the bracket 12 is constrained to move in the second displacement direction 106 (vertical direction), but resting constantly on the central body 8'.
  • the displacement of the central body 8, brought about by the rotation of the pinion 26 results in a lifting of the bracket 12 with respect to the axis 101 of the wheel 5 and at the same time results in the central body 8 being slid in a first sense (denoted by the reference 1 0 in Fig. 9) of the direction 100 with respect to said bracket.
  • the raising of the bracket 12, which is the desired effect in this case, is of course proportional to the angle of rotation of the pinion 26 about the reference axis 102.
  • the adjustment tool 300 would have to be rotated in the opposite direction from in the previous case, in other words clockwise. This would bring about displacement of the central body 8 in the opposite direction from in the previous case. More specifically, the first grooves 18', 18" would bring about a displacement of the central body 8 in the first direction 105 in a "lowering" sense (arrow 302 in Fig. 9). This displacement would ultimately lead to vertical lowering of the bracket 12 and sliding of the central body 8 with respect to said bracket in a second sense (denoted by the reference 111 in Fig. 9) of the movement direction 100 counter to the aforementioned first sense (110).
  • the second grooves 19', 19" thus have the effect not only of guiding the displacement of the bracket 12, but also of making it possible for said bracket to rest constantly on the central body 8 under gravity. This means that the weight of the door 51 is advantageously also supported by the central body 8. This ensures a high mechanical resistance in particular to bending stresses. It should be added that the simultaneous presence of the first grooves 18', 18" and the second grooves 19', 19" makes the adjustment mechanism particularly reliable as regards maintaining the assigned position of the bracket 12 after adjustment.
  • the second grooves 19', 19" block any undesired sliding of the central body 8 in the first direction 105 defined by the first grooves 18', 18", in practice by generating constraining and frictional conditions which hold the central body 8 and the bracket 12 stably in the respective positions which are reached at the end of the adjustment.
  • Fig. 7 is a plan view from which a further advantageous peculiarity of the movement unit 1 ' according to the present invention can be seen.

  • frontal adjustment which is simultaneously "central” does not require positioning of the activation element as a function of the door to be moved. This aspect is extremely advantageous in terms of production and makes both the installation operations and any subsequent replacement/maintenance operations on the movement unit 1 ' much easier.

  • Said unit 1 " is for moving the inner door 52 of the wardrobe 2, and is analogous in construction and operation to the outer unit 1 ' described in detail above.

At the same time, it is noted that the distance between the anchoring portion 12' and the first bearing portion 13' is much more compact than is provided for the outer unit 1 '.

  • the pinion 26 could be produced in a single piece with the tool 300.
  • Fig. 15 shows a particular tool, similar in construction to a screwdriver, the end of which specifically defines the pinion 26.
  • the access opening 46 makes it possible to engage the pinion 26 in the rack 25 of the central body 8, in other words to locate the pinion 26 in the operative position necessary for activating the adjustment mechanism. Said opening 46. makes it possible subsequently to extract the pinion 26 at the end of the adjustment.
  • Fig. 16 to 22 show an alternative embodiment of the outer movement unit 1 ', which differs from those shown in Fig. 3 to 10 primarily by way of a different configuration of the activation means or a different configuration of the pinion 26 and the rack 25.
  • the pinion 26 is defined by a cylindrical drum (also referred to in the following as a cylindrical body), about which an external toothing, comprising two parts 27', 27" of toothing having an involute profile, develops. Said parts 27', 27" of toothing are specular with respect to a transverse reference plane 400 orthogonal to the axis of rotation of the pinion which is coincident with the reference axis 102 defined above.
  • Fig. 19 and 21 show the engagement situation of the activation means (rack 25, pinion 26) at two possible moments during the adjustment of the movement unit 1 '.
  • the rack 25 is defined on the transverse portion 9 (also shown in the exploded view of Fig. 18) of the central body 8, and comprises a series of substantially V-shaped grooves 28', 28" orientated in the same sense.

  • the inclined lines which define each of the grooves 28', 28" are of a width in accordance with the thickness of the corresponding involute parts 27', 27" of toothing of the pinion 26 so as to make meshing/catching possible.
  • this particular formation assigned to the activation means makes greater demultiplication of the rack- and-pinion transmission possible, or a more strongly reducing transmission, than what can be obtained using the straight teeth and grooves provided in the solutions shown in Fig. 3 to 15. Said demultiplication, i.e.
  • a more strongly reducing transmission ratio advantageously leads to a reduction in the force used to actuate the actuation and simultaneously to a more precise and stable adjustment without jerking/interruption by virtue of the continuous meshing/catching between the parts.
  • the pinion 26 having involute parts 27', 27" of toothing requires a greater number of rotations, but a much smaller force (torque applied using a tool 300) than when using a pinion 26 having straight teeth. This is of course to the advantage of the operators involved in the installation and adjustment operations.
  • the detailed view of Fig. 19 shows a first step of the possible adjustment of the movement unit 1 ', that is a first engagement situation of the pinion 26 (having involute parts 27', 27") in the V-shaped grooves of the rack 25.

  • This situation of simultaneous engagement of two adjacent grooves 28', 28" is obtained by virtue of the relative position of the two grooves 28', 28" whereby the vertex of the first groove 28' is located in a position substantially aligned with the ends (denoted by the reference 29) of the inclined parts of the second groove 28".
  • Said alignment situation is shown in Fig. 21 from a sketched reference direction 311 substantially parallel to the reference axis 02 (axis of rotation of the pinion 26).
  • Fig. 20 is a prospective view, which shows, purely illustratively, just one assembly of components (the central body 8, the wheel 5 and the activation means) during an adjustment step corresponding to the one shown in Fig. 19. From Fig. 20, it can be seen that the engagement position of the pinion 26 in the groove 25 defines a first height of the central body 8 with respect to the bearing plane of the wheel 5, identified by the distance having reference 108.
  • FIG. 21 shows a second step of the adjustment of the movement unit or a second engagement situation of the pinion 26 (having involute parts 27', 27" of toothing) in the V-shaped grooves of the rack 25.

  • the pinion 26 thus comprises an end 26' which faces the access opening 46 defined by the bracket 12 so as to make it possible for an adjustment tool 300 to pass through.
