Definitions
- the present invention concerns a hinge of the so-called retractable type, used for doors, windows and furniture, which comprises two hinging units, articulated with respect to each other by means of a central articulation member, one able to be inserted in a seating of a fixed structure, such as for example a frame of the door, window or piece of furniture, and the other able to be inserted in a seating of a corresponding movable structure, such as for example a door, a window, a shutter or a panel of a door, window or piece of furniture.
- the hinge allows the movable structure to be opened by 180° with respect to the fixed structure, and is able to be completely inserted into the respective structures, fixed and movable, when the latter is in the closed position.
- retractable hinges In the field of doors, windows and furniture, retractable hinges are known, that is, the type that, in the closed position, all the elements of which they consist are completely inserted inside the door, window or piece of furniture on which they are applied, so that they are not visible.
- a retractable hinge which comprises two hinging bodies, suitable to be associated with the fixed and movable parts of the door or window, and a central articulation member, connected to the hinging bodies so as to allow them to rotate reciprocally by about 180° around a central axis.
- the articulation member comprises two distinct pivoting elements, different from each other and each inserted in a corresponding cavity made on each of the two hinging bodies.
- the position of one of the pivoting elements with respect to the corresponding hinging body is adjustable in a longitudinal direction by means of a threaded grub screw.
- a first pair of longitudinal guides is present to guide the pivoting element precisely and allow it to be displaced only in said longitudinal direction.
- the position of the other pivoting element is adjustable, with respect to the corresponding hinging body, in a transverse direction, by means of a cam.
- a second pair of longitudinal guides is present to guide the other pivoting element precisely and allow it to be displaced only in said transverse direction.
- the articulation member also comprises two curved arms, different from each other, each pivoted on one of the two pivoting elements and having a central pin in common, on which articulation occurs.
- the segments of the two curved arms are different from each other, which go from the central pin to the point where they are pivoted on the corresponding pivoting element.
- By means of another threaded grub screw it is possible to adjust the distance between the two curved arms, in a vertical direction.
- This known hinge has the disadvantage that all the essential elements of which it consists, like the two pivoting elements and the two curved arms of the articulation member, are different from each other, and therefore they are more expensive to make and more complicated to assemble.
- EP-A-1780357 discloses a retractable hinge which also comprises two hinging bodies, suitable to be associated with the fixed and movable parts of the door or window, and a central articulation member, connected to the hinging bodies.
- this hinge a pair of adjustment mandrels are provided, which allow to adjust the depth of the articulation member with respect to one of the two hinging bodies, and a pair of adjustment screws, which are inserted with ample play in corresponding ovalized holes made in the other of the two hinging bodies and which allow to adjust simultaneously both the height and also the lateral position of the articulation member with respect to the corresponding hinging body.
- This known hinge has the disadvantage that at least two adjustments must be made using the same adjustment screws, and therefore the adjustments are difficult to obtain with great accuracy.
- JP-A-2002-121955 discloses another retractable hinge, similar to the previous ones, in which toothed guide elements are provided on each pivoting element to define a plurality of grooves, which on one face are disposed parallel to the longitudinal pivoting axis and on the other face are disposed perpendicular to the pivoting axis, so as to allow a reciprocal sliding with other corresponding grooves, both longitudinally and transversely, so as to adjust both the height and also the lateral position of each pivoting element.
- This known hinge also has the disadvantage that the same adjustment screw is used to make two different adjustments, and therefore the adjustments are difficult to obtain with great accuracy. Furthermore, this known hinge does not provide any possibility of adjusting the depth of the pivoting elements with respect to the hinging units.
- DE-B3-102004054708 discloses another retractable hinge in which the articulation member, which acts as an articulated connection between the two hinging bodies, has a rounded shape, like a horseshoe.
- This known hinge has the disadvantage that it is complex and above all very bulky.
- One purpose of the present invention is to achieve a retractable hinge to articulate a movable structure with respect to a fixed structure, which allows to effect, autonomously one with respect to the other, different adjustments on each of the two pivoting elements.
- Another purpose of the present invention is to achieve a retractable hinge in which adjustments can be made not only in the three Cartesian directions but also on the parallelism or on the convergence or divergence of the pivoting elements with respect to the bodies in which they are inserted.
- Another purpose of the present invention is to achieve a retractable hinge in which the elements of which it consists are identical to each other, as much as is possible, so as to render the hinge in its entirety less costly and easier to assemble.

Description
- The present invention concerns a hinge of the so-called retractable type, used for doors, windows and furniture, which comprises two hinging units, articulated with respect to each other by means of a central articulation member, one able to be inserted in a seating of a fixed structure, such as for example a frame of the door, window or piece of furniture, and the other able to be inserted in a seating of a corresponding movable structure, such as for example a door, a window, a shutter or a panel of a door, window or piece of furniture. The hinge allows the movable structure to be opened by 180° with respect to the fixed structure, and is able to be completely inserted into the respective structures, fixed and movable, when the latter is in the closed position.
- In the field of doors, windows and furniture, retractable hinges are known, that is, the type that, in the closed position, all the elements of which they consist are completely inserted inside the door, window or piece of furniture on which they are applied, so that they are not visible.
- In particular, a retractable hinge is known which comprises two hinging bodies, suitable to be associated with the fixed and movable parts of the door or window, and a central articulation member, connected to the hinging bodies so as to allow them to rotate reciprocally by about 180° around a central axis. The articulation member comprises two distinct pivoting elements, different from each other and each inserted in a corresponding cavity made on each of the two hinging bodies. The position of one of the pivoting elements with respect to the corresponding hinging body is adjustable in a longitudinal direction by means of a threaded grub screw. A first pair of longitudinal guides is present to guide the pivoting element precisely and allow it to be displaced only in said longitudinal direction. The position of the other pivoting element is adjustable, with respect to the corresponding hinging body, in a transverse direction, by means of a cam. A second pair of longitudinal guides is present to guide the other pivoting element precisely and allow it to be displaced only in said transverse direction. The articulation member also comprises two curved arms, different from each other, each pivoted on one of the two pivoting elements and having a central pin in common, on which articulation occurs. In particular, the segments of the two curved arms are different from each other, which go from the central pin to the point where they are pivoted on the corresponding pivoting element. By means of another threaded grub screw it is possible to adjust the distance between the two curved arms, in a vertical direction.
- This known hinge has the disadvantage that all the essential elements of which it consists, like the two pivoting elements and the two curved arms of the articulation member, are different from each other, and therefore they are more expensive to make and more complicated to assemble.
- Another disadvantage of this known hinge is the limited number of adjustments possible: in fact, the two pairs of guides, one longitudinal and the other transverse, allow only one adjustment in a longitudinal direction, that is, the adjustment of one of the two pivoting elements, and only one adjustment in a transverse direction, that is, the adjustment of the other of the two pivoting elements.
- Another disadvantage of the known hinge is that in order to carry out the three adjustments, two different tools are required.
-
EP-A-1780357 discloses a retractable hinge which also comprises two hinging bodies, suitable to be associated with the fixed and movable parts of the door or window, and a central articulation member, connected to the hinging bodies. In this hinge a pair of adjustment mandrels are provided, which allow to adjust the depth of the articulation member with respect to one of the two hinging bodies, and a pair of adjustment screws, which are inserted with ample play in corresponding ovalized holes made in the other of the two hinging bodies and which allow to adjust simultaneously both the height and also the lateral position of the articulation member with respect to the corresponding hinging body.

- According to another characteristic feature of the present invention, with the four adjustment means it is possible to adjust not only the reciprocal position of the articulation member with respect to the two hinging units along the three Cartesian axes (X, Y and Z), but also to adjust the inclination of the hinging units both frontally and laterally, so as to obtain the desired parallelism, or a possible convergence or divergence, of the individual parts, depending on the specific assembly requirements of the door or window or piece of furniture.
- More specifically, the articulation member comprises two pivoting elements able to be inserted slidingly, one in the first and the other in the second hinging unit. According to another characteristic feature of the present invention, the two pivoting elements are structurally identical to each other, and are assembled in the two hinging units rotated by 180° one with respect to the other.
- According to another characteristic feature of the present invention, the articulation member also comprises two comb elements, structurally identical to each other, but assembled on the two pivoting elements rotated by 180° with respect to each other and interconnected with each other. In this case, each of the two comb elements comprises a lateral stem, parallel to the central axis (Z), pivoted on one of the pivoting elements and from which two curved arms branch off cantilevered, both perpendicular to the lateral stem and each having a through hole coaxial to the central axis (Z), in which a central pin is inserted, common to both the comb elements.
- According to another characteristic feature of the present invention, each of the two lateral stems is rotatable on a lateral pin disposed in a corresponding pivoting element, parallel to the central axis, and each of the two curved arms comprises a first segment with an equal length, comprised between the through hole and the corresponding lateral pin.
- In this case, the first adjustment means comprise two first guide blocks, disposed in one of the hinging units and inserted with play in corresponding slits of one of the pivoting elements. Furthermore, the first guide blocks are each provided with an eyelet inside which a first adjustment screw is inserted, with ample play.
- The second adjustment means comprise two second guide blocks, disposed with ample play in the other hinging unit, and two second adjustment screws each cooperating with one of the second guide blocks in order to move it autonomously along the longitudinal axis (X).
- The third adjustment means comprise two third adjustment screws, each through, with ample play, in a first pair of transverse eyelets of the second pivoting element and screwed onto the first guide blocks.
- The fourth adjustment means comprise two fourth adjustment screws, each through, with ample play, in a second pair of transverse eyelets of the first pivoting element and screwed onto the second guide blocks.

- With reference to
fig. 1 , ahinge 10 of the retractable type, according to the present invention is used to articulate amovable structure 12, for example the panel of a door or window or piece of furniture, with respect to afixed structure 13, for example the frame of the door or window or piece of furniture, between a first position (fig. 2 ), in which themovable structure 12 is closed with respect to thefixed structure 13, and a second position (figs. 1 and3 ) in which themovable structure 12 is open with respect to thefixed structure 13. In the position of maximum opening (fig. 3 ), themovable structure 12 is rotated by 180° with respect to when it is in its closed position (fig. 2 ). Furthermore, in this last position, thehinge 10 is completely inside thestructures - The
hinge 10 comprises afirst hinging unit 16, able to be inserted in a hollow seating 18 (figs. 2 and 3 ) of themovable structure 12, and asecond hinging unit 17 able to be inserted in ahollow seating 19 of the fixedstructure 13. - The
hinge 10 also comprises an articulation member 20 (figs. 1 to 4 and7 to 10 ) connected to the two hingingunits figs. 1 and4 ). - Each hinging
unit figs. 4 and10 ), respectively 22, for example made of metal, provided with acavity 23, respectively 24, inside which is inserted, with play and slidingly, afirst pivoting element 25, respectively asecond pivoting element 26 of thearticulation member 20. In particular, the height of thecavity 24 is greater than that of thecavity 23. - Each
body upper fin 31, respectively 32, and alower fin 33, respectively 34, provided with flaredholes 35 in which screws 36 (fig. 1 ) are able to be disposed in order to attach thebodies structures - The two pivoting
elements 25 and 26 (figs. 4 and10 ) of thearticulation member 20 are identical to each other and each comprise a block, for example metal, provided with aninternal cavity 41, respectively 42, in which alateral pin 43 is disposed (figs. 4 ,7, 8 and 9 ), respectively 44, parallel to the central axis Z. - The
first pivoting element 25 can slide in thecavity 23 of thebody 21 both along a longitudinal axis X (figs. 1 and5 ), perpendicular to the central axis Z, and also along a transverse axis Y (figs. 1 and4 ), perpendicular to the central axis Z and to the longitudinal axis X, as will be described in more detail hereafter. - The
second pivoting element 26 slides in thecavity 24 of thebody 22 both along the central axis Z, and also along the transverse axis Y, as will be described in more detail hereafter. - Each of the two pivoting
elements fig. 4 ), through which it is possible to insert a tool to move the pivotingelement body 21, respectively 22. - As well as the two pivoting
elements articulation member 20 also comprises twocomb elements 51 and 52 (figs. 4 and10 ), identical to each other, which each comprise alateral stem 53, respectively 54, parallel to the central axis Z and pivoted on thelateral pin 43, respectively 44, of the pivotingelement 25, respectively 26. From eachlateral stem curved arms 55, respectively 56, branch off, cantilevered and perpendicular thereto, each one having a throughhole 57 respectively 58, coaxial to the central axis Z, in which a central pin 59 (fig. 4 ) is inserted, common to the twocomb elements - Each of the two
comb elements roller 61, respectively 62, mounted at the end of the twocurved arms 55, respectively 56, parallel to the central axis Z and sliding in a corresponding longitudinal seating 66 (figs. 7 to 9 ), respectively 65, made in theinternal cavity 42, respectively 41, of the corresponding pivotingelement - Each
curved arm first segment 55a (fig. 7 ), respectively 56a, comprised between the throughhole 57, respectively 58, in which thecentral pin 59, and thelateral pin 43, respectively 44, is inserted, and having a determinate distance d, which is the same for all fourarms - The two
internal cavities elements comb elements hinge 10 is in the closed position (fig. 2 ). - The
hinge 10 also comprises first adjustment means 70 (figs. 6 and10 ), which allow to adjust the reciprocal axial position, parallel to the central axis Z, of thefirst hinging unit 16 with respect to thesecond hinging unit 17. The first adjustment means 70 comprise two guide blocks 71, one disposed in the upper part 26a and the other in the lower part 26b of thecavity 24 of thebody 22 and inserted with play in twocorresponding slits 72 of thesecond pivoting element 26. The two guide blocks 71 are each provided with aneyelet 75 and are held in the two parts 26a and 26b of thecavity 24 by two closingelements 73 and by two corresponding adjustment screws 74, but can slide with respect to thecavity 24 thanks to the ample play, in the range of several millimeters, between theeyelet 75 and theadjustment screw 74. - We must point out that, while the height of the
cavity 23 is substantially the same as that of thefirst pivoting element 25, the height of thecavity 24 is greater, by some millimeters, for example 4 to 8, than the height of thesecond pivoting element 26, and therefore the latter and hence thewhole articulation member 20 can slide with respect to thesecond hinging unit 17, parallel to the central axis Z. - The
second pivoting element 26 is clamped in the desired position with respect to thebody 22 of thesecond hinging unit 17 by means of twoadjustment screws 76, each passing through a pair oftransverse eyelets 77 of the pivotingelement 26 and screwed onto thecorresponding guide block 71. The amplitude of thetransverse eyelets 77, some millimeters greater than the diameter of the adjustment screws 76, allows to adjust thesecond pivoting element 26 along the transverse axis Y with respect to thesecond hinging unit 17. - The
hinge 10 also comprises second adjustment means 80 (figs. 5 and10 ), which allow to adjust the longitudinal position of thefirst pivoting element 25, and hence of thewhole articulation member 20, with respect to thefirst hinging unit 16 along the longitudinal axis X. The second adjustment means 80 comprise two guide blocks 81, one disposed in the upper part and the other in the lower part of thecavity 23 of thebody 21. The two guide blocks 81 are housed with ample play, in the range of several millimeters, for example 4 to 8, in two slits of thecavity 23. Two adjustment screws 84 are freely rotatable in correspondinglongitudinal holes 85 of thebody 21 and are held in a longitudinal position by twotransverse pegs 86. The twoadjustment screws 84 are screwed into two corresponding threadedholes 87 each made on aguide block 81. - The two guide blocks 81 are also inserted with play into two corresponding
slits 82 of thefirst pivoting element 25. The latter is held constrained to the two guide blocks 81 by means of twoadjustment screws 88, each passing through a pair oftransverse eyelets 89, made in correspondence with theslits 82 of the pivotingelement 25 and screwed onto thecorresponding guide block 81. - In this way, by turning the two
adjustment screws 84 clockwise or anticlockwise, it is possible to move thefirst pivoting element 25 along the longitudinal axis X, and hence thewhole articulation member 20, with respect to thefirst hinging unit 16. Furthermore, by adjusting autonomously each of the two adjustment screws 84 (fig. 5 ), it is also possible to incline frontally thefirst pivoting element 25, and hence thewhole articulation member 20 and the associated second hingingunit 17, with respect to thefirst hinging unit 16, so as to align it or incline it by some degrees in one direction or the other. - Furthermore, the amplitude of the
transverse eyelets 89, some millimeters greater than the diameter of the adjustment screws 88, allows to adjust the first pivoting element along the transverse axis Y with respect to thefirst hinging unit 16. - In addition, thanks to the ample play between the
transverse eyelets units 16 and 17 (fig. 4 ) with respect to the central axis Z, and/or their possible convergence or divergence. - The
hinge 10 as described heretofore is assembled and functions as follows. - First of all the
articulation member 20 is assembled, by pivoting thecomb elements elements - Then the guide blocks 71 and 81 are disposed in the upper and lower parts of the
cavities 23, respectively 24, of thebodies - Then the two pivoting
elements cavities 23, respectively 24, of thebodies slits transverse eyelets 77, respectively 89. - The
hinge 10 thus assembled is then mounted in thestructures bodies units hollow seatings units respective structures screws 36. - Then the various adjustment are made to the parts of the
hinge 10 along the axes X, Y and Z so as to modify, according to the requirements of the individual application, the position of one hingingunit 16 with respect to the other 17 and consequently the position of themovable structure 12 with respect to the fixedstructure 13. - By means of the adjustment screws 74, and thanks to the ample play between them and the eyelets 75 (
figs. 4 and 6 ) of theblocks 71, the position is thus adjusted along the central axis Z of thearticulation member 20 with respect to thesecond hinging unit 17. In other words, by means of the adjustment screws 74 it is possible to adjust the vertical position of the movable structure 12 (fig. 1 ) with respect to the fixedstructure 13. - By means of the adjustment screws 84, which are able to move each of the two guide blocks 81 in a longitudinal direction and autonomously, the position is adjusted along the longitudinal axis X of the
first pivoting element 25, and hence of thewhole articulation member 20, with respect to thefirst hinging unit 16. In other words, by means of the adjustment screws 84 it is possible to adjust the front position, in the closed position, of the movable structure 12 (fig. 2 ) with respect to the fixedstructure 13. - Furthermore, operating autonomously on each of the two
adjustment screws 84, it is also possible to correct the front parallelism of themovable structure 12 and the fixedstructure 13, inclining the first pivoting element 25 (fig. 5 ) to a greater or lesser extent with respect to the correspondingbody 21 of thefirst hinging unit 16. - By means of the adjustment screws 76 and 88 (
fig. 4 ) and thanks to the ample play between them and thetransverse eyelets 77, respectively 79, of theblocks elements corresponding hinging unit figs. 3 and4 ) with respect to the fixedstructure 13, operating both on thefirst pivoting element 25 and on thesecond pivoting element 26, and on both. Furthermore, by means of the adjustment screws 76 and 88, it is also possible to adjust the lateral parallelism, that is, with respect to the central axis Z, or the convergence or divergence from this of themovable structure 12, in the open position, with respect to the fixedstructure 13. - From the foregoing description it is clear that the
hinge 10 is provided with adjustment means that are simple, reliable and easy to use, which allow to adjust the position of the two hingingunits articulation member 20, both in a vertical direction (axis Z), in a front direction (axis X), in a horizontal or lateral direction (axis Y), with possible inclinations in a front direction (with respect to axis X) and/or in a convergent or divergent direction (with respect to axis Z). - It is understood that modifications and/or additions of parts may be made to the
hinge 10 as described heretofore, without departing from the field and scope of the present invention. - It is also clear that, although the present invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of retractable hinge for doors, windows or furniture, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
