Definitions
- the present invention relates to an adjustable retractable hinge.
- hinges are made of particular components used for articulating two elements to each other and, in the case in hand, a door (of a wardrobe or a door leaf) to a fixed structure or jamb (of a wardrobe or a door leaf).
- hinges those of the so-called “retractable” type are also known, which hinges are invisible when the door is closed, on one hand, and allow to perform rotation movements of the door up to approximately 180°, on the other.
- they comprise two bodies which are embedded in the thickness of the door and of the jamb and are connected to each other by a pair of arms which allow indeed the rotation of a body with respect to each other, and thus of the door, with respect to the jamb.
- Each of the two arms is articulated to the other in a zone comprised between the two ends and has one end articulated to one of the two hinge bodies and the other sliding along the other body.
- those of the adjustable type are also known, which hinges comprise two flanged containers or "cups", which are embedded in the thickness of the door and of the jamb and which define an accommodating housing for the respective hinge bodies, which are connected to each other by the pair of articulated arms.
- the adjustment of the hinge is generally obtained by virtue of the relative mobility of each hinge body within the respective cup.
- the traditional adjustable retractable hinges are not fully satisfactory because in order to adjust the distance that the two hinge bodies must have in facing condition, i.e. the distance between door and jamb when the door it closed, it is necessary to operate on two different adjustment screws, which raise each hinge body or make them either protrude from or retract into the corresponding cup. It is easy to understand that such an operation is rather complicated because it requires to conveniently balance the action on two different adjustment screws.
- the traditional hinges have a rather limited range and therefore the housing cavity of the cup in the door is not centered with respect to its thickness but is instead slightly displaced towards its outer surface. Consequently, the door can be articulated only on one side of the jamb, i.e. either the right side or the left side, but cannot be articulated to either one of them as chosen.
- the hinge of which can be fitted indifferently either on the right or on the left with respect to the jamb, and in order to do this the cavity must be obtained in the center with respect to the thickness of the door, i.e. in equally distanced position between the two opposite edges which define the thickness of the door.
- the traditional hinges having a rather limited rotation range do not allow a complete 180° opening of the door with respect to the jamb.
- JP2007 177427 describes a hinge in which the two bodies which are accommodated within the containing cups consist of two separate parts, and in particular consist of an intermediate sliding element and a supporting element for the hinge articulation arms.
- the high number of components makes the construction of this hinge particularly complicated.
- This document discloses the features of the preamble of claim 1.
- the hinge 2 comprises two hinge bodies 4,6 accommodated in two containing housings 8,10, both cup-shaped, respectively.
- the second hinge body 6 is made in one piece, which is separate from the containing housing 10, within which said second body is accommodated.
- the first hinge body 4 is also made in one piece, which is separate from the containing housing 8, within which said first body is accommodated.
- the two containing housings 8,10 are intended to be embedded in a first housing recess and a second housing recess (not shown), obtained in a jamb and in the door, which must be articulated to the jamb, respectively.
- closed condition of the hinge means the condition in which the door is closed and coplanar with the jamb and the two hinge bodies 4,6, inserted in the respective containing housings 8,10, are facing each other.
- Open condition of the hinge instead, means the condition in which the door is completely open and is on a different, but parallel plane with respect to the jamb and the two hinge bodies 4,6, inserted in the respective containing housings 8,10, are facing each other.
- length means the development of the hinge body 4,6 along the direction (axis X) parallel to the articulation axis of the hinge 2
- width means the development of the hinge body along the direction (axis Y) orthogonal to the previous one and parallel to the thickness of the door or the jamb
- height/depth means the development of the hinge body along the embedding direction (axis Z) thereof in the door or jamb.
- the two containing housings 8,10 have substantially the same shape which comprises two flat end flanges 16,16' mutually separated by a substantially parallelepiped-shaped internally hollow portion 18,18'.
- guiding means 20 for the corresponding body 6 intended to be accommodated in said housing 10.
- these guiding means 20 comprise two protruding and parallel appendixes 21 which develop from the bottom 23 of the hollow portion 18' at the ends thereof.
- appendixes 21 work as guides for corresponding elongated cavities 24 obtained in other appendixes 25 of the body 6; in particular, the shape of the elongated cavities 24 and the corresponding appendixes 21 is such as to facilitate the insertion of the body 6 in the accommodation housing 10, as well as to allow the guided sliding along axis Z of said body 6 with respect to said housing 10 during the step of adjusting.
- the body 6 has a raised central zone 28 interposed between two hollow zones 29.
- this central raised zone 28 has an upper base 30 with a conformation substantially complementary to the outer surface of a central arm 52, described below, which in the closed hinge condition is intended to rest on said upper base 30 of said raised central zone 28. This makes the hinge particularly compact also when it is in the closed condition.
- an element is provided for adjusting its movements along axis Z, following the either greater or lesser insertion depth thereof in the corresponding accommodation housing 10.
- this adjustment element comprises a screw 41 which is accommodated in a flared hole 32 obtained in said central zone 28 parallel to axis Z and is prevented from performing axial movements within its housing by a pair of parallel pins 42 inserted in specific holes 34, made in the side surface of the body itself parallel to axis Y.
- the adjustment of the depth (i.e. along axis Z) of the body 6 in the accommodation housing 10 is obtained by screwing the threaded portion of the screw 41 into an appropriate threaded hole 35 obtained on the bottom 23 of the accommodation housing itself.
- the same adjustment element 41 which allows to adjust the depth of the body 6 within its accommodation housing 10, also guarantees the fixing and the coupling of the body 6 to its housing 10.
- connection between the two bodies 4 and 6 is obtained by means of three rocker-shaped arms, of which one central 52 and two outer 54, 56.
- the length of the raised central zone 28 of the body 6 is substantially equal to the lateral development of the central portion of the central arm 52 (i.e. without the two side appendixes 53), while the length of each hollow zone 29 is substantially equal to the lateral development (i.e. along axis X) of the respective central portion of the outer arm 54,56.
- the guides 67, obtained in the body 6, of the appendixes 60 of the outer arms 54, 56 have a pattern with a first stretch 70 inclined and open at the top. This is particularly advantageous because it facilitates the assembly of the hinge, in particular by facilitating the insertion of the arms 54, 56 from the upper base 30 of the body 6.
- the first stretch 70 then extends along a second stretch 72, which is laterally inclined in opposite manner with respect to the direction of development of the first.
- the first stretch 70 and the second stretch 72 are consecutive and, more in detail, as shown in fig. 6 , the direction of development of the second stretch 72 defines an obtuse angle with the direction of development of the first stretch 70.
- Such a conformation of the guides 67 is particularly advantageous because it implies that, during the step of opening and closing of the door 14, the door is subjected to a particular composite movement, which avoids the interference with the vertical edge of the jamb 12
- the height of the body 6, intended to be accommodated in the housing 10 to be applied to the door is greater than the height of the other body 4, while the width of the latter is advantageously smaller than the housing 8 which accommodates it, in order to limit the adjustment movements along direction Y within the housing itself.
- first slots 42 are obtained, which can be crossed by screws for stably fixing the body itself in the respective recess obtained in the jamb. These first slots 42 develop along direction X and allow to adjust the position of the housing 10 in the embedding cavity made in the door, and thus to adjust the door in this direction.
- Substantially circular holes 43 which can be crossed by screws for stably fixing the body itself in the respective embedding cavity made in the door, are obtained on the flange 16 of the containing housing 8 intended to be embedded in the housing.

Furthermore, a cam 76 is provided in the body 4, which cam can be accessed from the upper base of the body itself, cooperates with a corresponding cavity 79 obtained on the bottom of the containing housing 8 and with its rotation adjusts the position of said body 4 with respect to its housing 8 along direction Y.
- third slots 48 are obtained on the flange 16, 16' of both containing housings 8, 10 of the two bodies 4, 6, which slots can be engaged by corresponding appendixes obtained in covering masks 50 of the recesses for their interlocking coupling.

Description
- The present invention relates to an adjustable retractable hinge.
- It is well known that hinges are made of particular components used for articulating two elements to each other and, in the case in hand, a door (of a wardrobe or a door leaf) to a fixed structure or jamb (of a wardrobe or a door leaf).
- Among the hinges, those of the so-called "retractable" type are also known, which hinges are invisible when the door is closed, on one hand, and allow to perform rotation movements of the door up to approximately 180°, on the other. In particular, they comprise two bodies which are embedded in the thickness of the door and of the jamb and are connected to each other by a pair of arms which allow indeed the rotation of a body with respect to each other, and thus of the door, with respect to the jamb. Each of the two arms is articulated to the other in a zone comprised between the two ends and has one end articulated to one of the two hinge bodies and the other sliding along the other body.
- Among the retractable hinges, those of the adjustable type are also known, which hinges comprise two flanged containers or "cups", which are embedded in the thickness of the door and of the jamb and which define an accommodating housing for the respective hinge bodies, which are connected to each other by the pair of articulated arms. The adjustment of the hinge is generally obtained by virtue of the relative mobility of each hinge body within the respective cup.
- However, the traditional adjustable retractable hinges are not fully satisfactory because in order to adjust the distance that the two hinge bodies must have in facing condition, i.e. the distance between door and jamb when the door it closed, it is necessary to operate on two different adjustment screws, which raise each hinge body or make them either protrude from or retract into the corresponding cup. It is easy to understand that such an operation is rather complicated because it requires to conveniently balance the action on two different adjustment screws.
- Generally, the traditional hinges have a rather limited range and therefore the housing cavity of the cup in the door is not centered with respect to its thickness but is instead slightly displaced towards its outer surface. Consequently, the door can be articulated only on one side of the jamb, i.e. either the right side or the left side, but cannot be articulated to either one of them as chosen.
- Currently, instead, the market requires a door the hinge of which can be fitted indifferently either on the right or on the left with respect to the jamb, and in order to do this the cavity must be obtained in the center with respect to the thickness of the door, i.e. in equally distanced position between the two opposite edges which define the thickness of the door. However, in such an installation mode, the traditional hinges having a rather limited rotation range do not allow a complete 180° opening of the door with respect to the jamb.
-
JP2007 177427 - It is the object of the invention to make an adjustable hinge which may be installed in a cavity obtained in centered position with respect to the thickness of the door, and which allows a complete 180° opening of the door with respect to the jamb at the same time.
- It is another object of the invention to make an adjustable retractable hinge which is more compact and smaller than the similar traditional hinges.
- It is another object of the invention to make a hinge which can be installed and adjusted in simple, easy, quick and accurate manner with respect to the jamb in all directions.
- It is another object of the invention to make a hinge in which it is sufficient to operate on a single element to adjust the direction of its greater or lesser depth.
- It is another object of the invention to make an adjustable hinge with a reduced number of components.
- It is another object of the invention to make a hinge which is simple and rapid to assemble. It is another object of the invention to make an adjustable hinge which allows a greater range with respect to the traditional ones.
- It is another object of the invention to make an adjustable hinge of much lower cost than the similar traditional hinges.
- It is another object of the invention to make an adjustable hinge which is aesthetically pleasing when seen once installed in the jamb and in the door.
- It is another object of the invention to make an adjustable hinge which has an alternative characterization, both in construction and functional terms, with respect to the traditional hinges.
- These objects, taken individually and in any combination thereof, as well as others which will result from the following description, are achieved according to the invention by a perfected hinge having the features of claim 1.
- The present invention is further explained with some preferred embodiments given by way of non-limiting example only with reference to the accompanying drawings, in which:
- figure 1
- is a perspective view from the top of the hinge according to the invention,
- figure 2
- is a plan view thereof,
- figure 3
- is an exploded perspective view thereof, and
- figure 4
- is a longitudinal section thereof taken along IV-IV in
figure 2 , - figure 5
- is a longitudinal section thereof taken along V-V in
figure 2 , and - figure 6
- is a cross section thereof taken along IV-IV in
figure 2 . - As can be seen in the figures, the
hinge 2 according to the invention comprises twohinge bodies housings - The
second hinge body 6 is made in one piece, which is separate from the containinghousing 10, within which said second body is accommodated. Preferably, thefirst hinge body 4 is also made in one piece, which is separate from the containinghousing 8, within which said first body is accommodated. - The two containing
housings - It is worth noting that hereinafter, "closed" condition of the hinge means the condition in which the door is closed and coplanar with the jamb and the two
hinge bodies housings - "Open" condition of the hinge, instead, means the condition in which the door is completely open and is on a different, but parallel plane with respect to the jamb and the two
hinge bodies housings - Furthermore, it is worth noting that hereinafter length means the development of the
hinge body hinge 2, width means the development of the hinge body along the direction (axis Y) orthogonal to the previous one and parallel to the thickness of the door or the jamb, and height/depth means the development of the hinge body along the embedding direction (axis Z) thereof in the door or jamb. - The two containing
housings flat end flanges 16,16' mutually separated by a substantially parallelepiped-shaped internallyhollow portion 18,18'. - Within the hollow portion 18' of the containing
housing 10, i.e. the hollow portion of the containing housing intended to be embedded in the door, there are provided guidingmeans 20 for thecorresponding body 6 intended to be accommodated in saidhousing 10. - More in detail, these guiding means 20 comprise two protruding and
parallel appendixes 21 which develop from thebottom 23 of the hollow portion 18' at the ends thereof. - These
appendixes 21 work as guides for correspondingelongated cavities 24 obtained inother appendixes 25 of thebody 6; in particular, the shape of theelongated cavities 24 and thecorresponding appendixes 21 is such as to facilitate the insertion of thebody 6 in theaccommodation housing 10, as well as to allow the guided sliding along axis Z ofsaid body 6 with respect to saidhousing 10 during the step of adjusting. - The
body 6 has a raisedcentral zone 28 interposed between twohollow zones 29. Conveniently, this central raisedzone 28 has anupper base 30 with a conformation substantially complementary to the outer surface of acentral arm 52, described below, which in the closed hinge condition is intended to rest on saidupper base 30 of said raisedcentral zone 28. This makes the hinge particularly compact also when it is in the closed condition. - Furthermore, in the central raised
zone 28 of thebody 6, which is intended to be constrained to the door, an element is provided for adjusting its movements along axis Z, following the either greater or lesser insertion depth thereof in thecorresponding accommodation housing 10. - In particular, this adjustment element comprises a
screw 41 which is accommodated in aflared hole 32 obtained in saidcentral zone 28 parallel to axis Z and is prevented from performing axial movements within its housing by a pair ofparallel pins 42 inserted inspecific holes 34, made in the side surface of the body itself parallel to axis Y. - The adjustment of the depth (i.e. along axis Z) of the
body 6 in theaccommodation housing 10 is obtained by screwing the threaded portion of thescrew 41 into an appropriate threadedhole 35 obtained on thebottom 23 of the accommodation housing itself. - Advantageously, the
same adjustment element 41, which allows to adjust the depth of thebody 6 within itsaccommodation housing 10, also guarantees the fixing and the coupling of thebody 6 to itshousing 10. - The connection between the two
bodies - In particular, the central arm 52:
- has a pair of
cylindrical side appendixes 53 at a first end for articulating to thebody 6 by means of apin 62; the length of eachappendix 53, excluding the part which engages in thebody 4, is substantially equal to the lateral development (i.e. along axis X) of the central portion of each of the twoouter arms - slides with the other end along a pair of facing
guides 65, obtained in thebody 4 and engaged by a pair ofend appendixes 64, provided in the arm itself, - is articulated by its central portion to the
outer arms common pin 56. - Correspondingly, the two
outer arms 54 and 56: - are articulated by an end to the
body 4 by means of apin 66, which crosses the correspondingappendixes 55 protruding laterally inwards from each arm and having overall length substantially equal to the lateral development (i.e. along axis X) of the central portion of thecentral arm 52, - slide with
appendixes 60, protruding laterally from the other end, along a pair of facing guides 67, obtained in the side walls which delimit thehollow zones 29 of thebody 6, - are articulated by the central portion to the
central arm 52 at saidcommon pin 58. - When the door rotates with respect to the jamb from the closing condition to the opening condition, the
arms hinge 2 rotate about the various articulation pins 62, 66, 58, while therespective appendixes - Conveniently, the length of the raised
central zone 28 of the body 6 (i.e. the development along axis X) is substantially equal to the lateral development of the central portion of the central arm 52 (i.e. without the two side appendixes 53), while the length of eachhollow zone 29 is substantially equal to the lateral development (i.e. along axis X) of the respective central portion of theouter arm - Preferably, the
guides 67, obtained in thebody 6, of theappendixes 60 of theouter arms first stretch 70 inclined and open at the top. This is particularly advantageous because it facilitates the assembly of the hinge, in particular by facilitating the insertion of thearms upper base 30 of thebody 6. - Advantageously, the
first stretch 70 then extends along asecond stretch 72, which is laterally inclined in opposite manner with respect to the direction of development of the first. In particular, thefirst stretch 70 and thesecond stretch 72 are consecutive and, more in detail, as shown infig. 6 , the direction of development of thesecond stretch 72 defines an obtuse angle with the direction of development of thefirst stretch 70. - Such a conformation of the
guides 67 is particularly advantageous because it implies that, during the step of opening and closing of the door 14, the door is subjected to a particular composite movement, which avoids the interference with the vertical edge of the jamb 12 - Preferably, the height of the
body 6, intended to be accommodated in thehousing 10 to be applied to the door, is greater than the height of theother body 4, while the width of the latter is advantageously smaller than thehousing 8 which accommodates it, in order to limit the adjustment movements along direction Y within the housing itself. - Furthermore, on the flange 16' of the containing
housing 10first slots 42 are obtained, which can be crossed by screws for stably fixing the body itself in the respective recess obtained in the jamb. Thesefirst slots 42 develop along direction X and allow to adjust the position of thehousing 10 in the embedding cavity made in the door, and thus to adjust the door in this direction. - Substantially
circular holes 43, which can be crossed by screws for stably fixing the body itself in the respective embedding cavity made in the door, are obtained on theflange 16 of the containinghousing 8 intended to be embedded in the housing. -
Appendixes 45 are conveniently defined in thebody 4, in which appendixes second slots 46' are obtained, which can be crossed byscrews 77 for stably fixing the body itself in the respective containinghousing 8. Furthermore, acam 76 is provided in thebody 4, which cam can be accessed from the upper base of the body itself, cooperates with a correspondingcavity 79 obtained on the bottom of the containinghousing 8 and with its rotation adjusts the position of saidbody 4 with respect to itshousing 8 along direction Y. - Substantially, in order to adjust
hinge 2 along axis Y, firstly the fixing screws 77 are slightly loosened and then thecam 76 is turned by operating on its upper accessible end until thebody 4 moves in its containinghousing 8 along axis Y by the desired extent. - Furthermore,
third slots 48 are obtained on theflange 16, 16' of both containinghousings bodies masks 50 of the recesses for their interlocking coupling. - In an embodiment not shown here, the
body 4, i.e. the body intended to be coupled in the cavity obtained in the jamb, may be made in one piece with its corresponding containinghousing 8. - Conveniently, in this case, there are neither the fixing screws 77 nor the
cam 76, and additionally, instead of thecircular holes 43, slots are obtained which develop along the direction Y and which allow to adjust the position of thebody 4, made in one piece with itscorresponding housing 8, in the embedding cavity made in the jamb and to thus adjust the hinge along this direction. - In the embodiment shown and described above, the
body 6 is intended to be inserted in the cavity obtained in the door, while thebody 4 is intended to be inserted in the cavity obtained in the jamb, however it is understood that, in an alternative embodiment not shown here, thebody 6 may be inserted in the cavity obtained in the jamb, while thebody 4 may be inserted in the cavity obtained in the door. In other words, in such an alternative embodiment, the configuration is substantially reversed with respect to the one described and shown above. - From the above it is apparent that the retractable adjustable hinge according to the invention is more advantageous than the traditional retractable adjustable hinges, because:
- it is smaller in size,
- it has a greater range, the dimensions and materials being equal,
- it consists of a reduced number of components and, therefore, is simpler and easier to use, and thus also less expensive,
- it allows to adjust the hinge easily and rapidly, eliminating the risk of lateral waving, because the adjustment of the body in its containing housing is obtained by operating on a single point, at a central screw, which thus causes a pure and uniform translation movement of the body itself along the side guides, which are equally distanced with respect to the central screw,
- it is simple and rapid to assemble,
- it has a considerable articulation range, thus allowing a greater distance between the respective containing housings when they are in side-by-side configuration (i.e. when the door is open and turned by 180° with respect to the jamb); in particular, this allows to mill the embedding cavity of the hinge in the door in position equally distanced from the two front surfaces, and thus allows to articulate the door itself both on the right side and on the left side of the door.
- In particular, the retractable adjustable hinge according to the invention differs from
JP2007 177427 - the respective bodies, which are accommodated within the corresponding containing cups, are made in one piece and advantageously this considerably simplifies the manufacturing and assembly of the hinge itself,
- the adjustment of the depth of the body within its containing housing is obtained exclusively by operating on the adjustment screw provided at the central portion of the body itself, without any need to loosen further fixing screws, which indeed are not provided; this allows to speed up and considerably simplify such an adjustable operation,
