FIG. 6 is a section view of a preferred but not exclusive embodiment of the adjustingelement 110. - With reference to the above mentioned figures, the
hinge 1 can be used for the controlled rotatable movement of at least one closing element, such as a door, a shutter or the like, which may be, in a per se known way, anchored to a stationary support structure, such as a wall, a floor, a frame or the like. - As a non-limiting example, the
hinge 1 may be used for glass doors, interior doors made of wood, aluminium or PVC, shower doors or refrigerator doors. - As per se known, in the annexed figures neither the closing element nor the stationary support structure are shown. It is intended that both elements are not part of the invention claimed in the appended claims.
- Preferably, the
hinge 1 can be anchored to the stationary support structure in any way and lies above the floor level underlying the closing element. In other words, thehinge 1 is preferably not configured as a traditional floor door closer, of the type insertable in the floor through break-in works. - In a preferred but not exclusive embodiment, the
hinge 1 may include a box-shaped hinge inlet/outlet 10 which can be anchored to the closing element and apivot 20 which can be anchored to the stationary support structure. - However, it is understood that the
hinge 1 may also be free of thepivot 20, as taught for example in the international application PCT/IB2015/052183 on behalf of the same Applicant, which is referred to for consultation. In such case, the operational connection between the movable part and the fixed one of the hinge is ensured by a group of levers. - The box-
shaped hinge body 10 can be anchored to the closing element, while thepivot 20 can still be anchored to the stationary support structure as defined in the annexed claims. - The
pivot 20 and the box-shaped hinge body 10 are reciprocally coupled in order to rotate around the axis X, which, for example, may be substantially vertical. - Advantageously, the axis X can define the rotation axis of the closing element.
- The
hinge 1 includes anoperating chamber 13 defining a axis Y, which may be substantially perpendicular to the axis X, for example substantially horizontal. Within theoperating chamber 13, which may be inside the box-shaped hinge body 10, a plunger element 50 slides along the axis Y, on which counteracting elastic means 30 operates. - In such a way, the plunger element 50 can slide along the axis Y between one end-stroke position, corresponding to one of the opening position and the closing position of the
movable element 10, and a second end-stroke position, corresponding to the other position between the opening position and the closing position of themovable element 10. - Suitably, the
operating chamber 13 may include abottom wall 14 so that in the first end-stroke position, the plunger element 50 may be in a position proximal to thebottom wall 14, while in the second end-stroke position the same plunger element 50 may be in a distal position from thebottom wall 14. - In the embodiments shown in the figures, the proximal position corresponds to the closed position of the closing element, while the distal position corresponds to the open position of the opening element.
- On the other hand, the proximal position may correspond to the maximum elongation of the first counteracting elastic means 30, while the distal position may correspond to the maximum compression of the same.
- In fact, the first counteracting elastic means 30 may include one or more thrust springs, used for leading back the closing element in the closed position from the open position.
- In a preferred but not exclusive embodiment, the plunger element 50 may include a
cylindrical body 55, preferably airtight inserted in theoperating chamber 13. - The
pivot 20 and the plunger element 50 may each other be engaged so that the sliding of the latter along the axis Y between the proximal and distal positions corresponds to the rotation of the former around the axis X and, conversely, the rotation of the former around the axis X corresponds to the sliding of the second along the axis Y between the proximal and distal positions. - Such mutual engagement may be accomplished through known movement transmission means, for example through a
shaft 53 as better explained hereinafter. - For example, the
pivot 20 can include cam means 20' rotating around the axis X in order to move the plunger element 50 between the distal and proximal positions. - On the other hand, cam follower means 53" can be provided, interacting with the cam means 20' and integrally coupled with the plunger element 50, for example through the
shaft 53, in order to slide along the axis Y between the distal and proximal positions, as taught in the international patent applicationPCT/2015/052792 . - Suitably, the first counteracting elastic means 30 can operate on the plunger element 50 in order to lead it back to from the proximal position to the distal one.
- According to a different embodiment, not represented in the figures, the
shaft 53 may be not connected to the cam means 20' and /or to the cam follower means 53' and, more in general, to the transmission means of the hinge movement. - In a preferred but not exclusive embodiment, the
shaft 53 may be connected to thecylindrical body 55 through threading and counterthreading, as taught in the international applicationPCT/IB2015/052183 shaft 53 may be telescopically coupled with theabutment surface 14, in order to move jointly with thecylindrical body 55. - In another embodiment, the mechanical connection between the
cylindrical body 55 and theshaft 53 may occur in agreement with the teaching of the international applicationPCT/IB2012/051006 - The
hinge 1 also comprises damping means 40 for the reduction of the rotation speed of themovable element 10 when the plunger element 50 is in proximity of the second end-stroke position. Such damping means 40 reduce the speed of themovable element 10 used for the closure of the closing element. - In particular, depending on the configuration of such damping
means 40, as better explained hereinafter, thehinge 1 may have a damping action of the exclusively hydraulic type or hydraulic and mechanical type. - In case of mechanical hinge, in order to contrast the action of the plunger element 50, the damping
elements 40 may include second counteractingelastic means 41 interposed between the plunger element 50 and thebottom wall 14. In such case, the latter may therefore define a abutment surface for the second counteractingelastic means 41. - In particular, the second counteracting
elastic means 41 may have afirst end 42 towards the plunger element 50 and a second end 42' towards thebottom wall 14 and intended to go in beat against the same. On the other hand, the plunger element 50 may have afront portion 51 intended to go in beat with theend 42 of the second counteractingelastic means 41. - The second counteracting
elastic means 41 may pass from an unloaded position in which thefirst end 42 thereof ranges from thefront position 51 of the plunger element 50, shown for example inFIG. 1a , to a position of load start in which the latter is in contact with the first for loading the same means, shown for example inFIG. 1b . - From such position of load start, the second counteracting
elastic means 41, under the thrust of the plunger element 50 promoted by the action of the firstelastic means 30, may pass from the position of load start to a position of load end, shown for example inFIG. 1c , in which they are completely loaded in order to mechanically dampen the speed of the rotation of themovable element 10. - For example, the second elastic means 41 may include a spring, representing a
first end 42 susceptible to interact with thefront portion 51 and the opposite end 42' in beat with thebottom wall 14. - More in particular, the second counteracting
elastic means 41 may contrast the thrust of the plunger means 50 only for a section of its stroke. For example, the plunger element 50 may slide along a first section between the second end-stroke position, shown for example inFIG 1a , and an intermediate position, shown for example inFIG. 1b , corresponding to the position of load start of the second counteractingelastic means 41 without that the latter operate on the plunger element 50. - The latter, furthermore, may slide along a second section between the intermediate position here above and the first end-stroke position of the plunger element 50, shown for example in
FIG. 1c , corresponding to the position of load end of the second counteractingelastic means 41, along which the plunger element 50 itself undergoes the action of the second counteractingelastic means 41. - In other words, when the plunger element 50 advances from the intermediate position to the first end stroke position, this may correspond to the compression of the second counteracting
elastic means 41 which may be configured in order to operate a contrast action on the plunger element 50, the more compressed they are, the stronger the contrast action is. In such a way, the strongest contrast action is in correspondence with the first end-stroke position of the plunger element 50 to which the maximum compression of the second elastic means 41 may correspond. - Thanks to such features, it can mechanically checked, the closing or the opening of the closing element.
- By suitably choosing the features of the second counteracting
elastic means 41, it is possible to obtain a more or less intense mechanical damping action. - For example, the second counteracting
elastic means 41 may include at least a compression spring, for example a spiral spring. - In particular, the
spring 41 may also be put on theshaft 53. - Suitably, in order to house the
spring 41, thecylindrical body 55 may have anelongated adjunct 55"extending itself coaxially to theshaft 53 towards theabutment surface 14 in order to define between the same a ring-shaped seat 51'. The latter may be used to house the second counteractingelastic means 41 when the latter are in start load position, in order to guide the compression. - Suitably, the plunger element 50 may also include a
abutment surface 52 faced towards a corresponding abutment surface 14' of the operatingchamber 13 and aimed at interacting with the latter in order to define the end-stroke of the former. In particular, thesurfaces 52, 14' may be in mutual beat when the plunger element 50 is in the first end-stroke position and they may be mutually spaced when the plunger element 50 is in the second end-stroke position. - In this way, advantageously, also in case that the plunger element 50 is pushed with high force towards the
bottom wall 14, thesurfaces 52, 14' can be in mutual beat in order to preserve the counteracting means elastic 41. - Besides this, such features allow to the
hinge 1 to keep over time its exact closing position. - The operating
chamber 13 includes a working fluid, generally oil, acting on the plunger element 50 in order to contrast its action, checking hydraulically in this way the closure and/or opening of the closing element. - It is understood that also just one
portion 15 of the operatingchamber 13 can include a working fluid without departing in this way from the scope of protection of the annexed claims. - The plunger element 50 divides the operating
chamber 13 in a first and second adjustable-volume spaces - The first and second adjustable-
volume spaces elastic means 30 is placed in thefirst space 18. - Suitably, the
cylindrical body 55 can be airtight inserted in the operatingchamber 13 so that the same can be the separation element of theportion 15 in the first and second adjustable-volume spaces - In the present document, with the definition "airtight inserted cylindrical body" and related ones it is understood that the
cylindrical body 55 is inserted in the operatingchamber 13 with minimum play, so that it is allowed to slide within the same, but preventing the working fluid from leaking through the cavity between the side surface of the cylindrical body itself 55' and the internal surface of the operatingchamber 13. - At least a first
hydraulic circuit 60 for allowing the passage of the working fluid between the first andsecond compartments hydraulic circuit 70 is foreseen. - According to a particular embodiment not according to the invention, and not represented in the figures, the
hydraulic circuit 60 and thehydraulic circuit 70 can substantially coincide. - At the opening of the closing element the working fluid passes from the
first compartment 18 to thesecond compartment 19 through the firsthydraulic circuit 60, while at the closure of the closing element the working fluid passes from thesecond compartment 19 to thefirst compartment 18 through the secondhydraulic circuit 70. - In particular, both the first and second
hydraulic circuits first compartment 18 to thesecond compartment 19 and conversely in order to operate a contrast action on the plunger element 50. In particular, due to this configuration, it can be predetermined a maximum movement speed of the plunger element 50 and, therefore, a rotation speed of themovable element 10. - According to an aspect of the invention, the
hydraulic circuit 60 can at least include afirst passage 58 in order to put in fluidic communication the first andsecond compartments compartment 18 to thecompartment 19. - The
hydraulic circuit 60 can be manufactured according to the teaching of the international patent applicationPCT/IB2014/063556 PCT/IB2015/052183 - In particular, the
hydraulic circuit 60 can comprise anoperating element 56 cooperating with thecylindrical body 55 for defining avalve seat 57 inside which there is a lock 57'. - The
shaft 53, thecylindrical body 55 and the operatingelement 56 each may comprise a respective hole, therebetween fluidically connected in order to define thepassage 58. - The
valve seat 57 and the respective lock 57', besides this, may be predisposed in correspondence with thepassage 58 in order to define a non-return valve. In particular, it selectively avoids the passage of the working fluid through thesame passage 58 upon one of the opening or the closure of the closing element, by forcing in this way the passage of the working fluid through the secondhydraulic circuit 70. - As shown in the annexed figures, the non-return valve may be configured in order to allow selectively the passage of the working fluid from the
first compartment 18 to the second compartment through thepassage 58 upon the opening of the closing element, and for avoiding it upon the closure. - In a preferred but not exclusive embodiment, the non-return valve may foresee the lock forced in closure by a small spring, as taught in the international application
PCT/IB2015/052183 - According to an aspect of the invention, the damping means 40 may comprise at least one or more channels having a predetermined section in order to check the quantity of oil passing through.
- In an embodiment of the hinge not according to the invention, shown for example in the FIG. from 1a to 1c, the channel may be single, since also second counteracting
elastic means 41 are foreseen. - On the other hand, as shown for example in embodiments according to the invention of FIGS. from 5a to 5c, there may be a couple of damping channels cooperating with the second counteracting
elastic means 41. - In such a way, the damping action of the damping means 40 is both mechanical and hydraulic.
- In other preferred but not exclusive embodiments of the invention, shown for example in the FIGs. from 2a to 4c, the damping means 40 foresees two channels without any second counteracting elastic means.
- In this way, the damping action of the damping means 40 is exclusively hydraulic.
- In any case, the second
hydraulic circuit 70 comprises at least onefirst channel 43 and onesecond channel 45. - The
first channel 43 has afirst inlet 44 in thesecond compartment 19 and a first outlet 44' in thefirst compartment 18. - In particular, the
first inlet 44 and the first outlet 44' may be fluidically decoupled from the plunger element 50 for the whole stroke thereof. - According to a particular embodiment, the
channel 43 may comprise ahelical groove 47 formed on the inner surface 15' of the operatingchamber 13. In particular, the outer surface 55' of thecylindrical body 55 may be aimed at interacting with the inner surface 15' and with thehelical groove 47 in order to define a helical channel. - In such case, the quantity of the working fluid passing from a compartment to the other is fixed and predetermined, depending from the dimensions of the
groove 47. - As a possibility, according to a different embodiment, the
channel 43 may be realized through thehinge body 10 outside the workingchamber 13. In such case, thechannel 43 may comprise oneelement 110 for adjusting the flow of the working fluid inside thereof, in order to regulate the flow of the passing fluid through thechannel 43 and so the extent of the hydraulic damping of the rotation speed of themovable element 10. - According to an embodiment not according to the invention shown in the
FIGs. 1a, 1b and 1c , thehinge 1 may comprise the second counteractingelastic means 41, thehydraulic circuit 60 andhydraulic circuit 70. In particular, the latter may comprise at least onechannel 43 having one or more characteristics described above comprising oneelement 110 for adjusting. - In this way, the counteracting action on the plunger element 50 practiced by the damping means 40 may be at the same time of mechanical and hydraulic type in order to exploit the synergic effect of the two actions and to obtain a more effective damping.
- The
element 110 for adjusting may comprise an adjustingscrew 111 of the known type for adjusting the passage section of thechannel 43, in order to regulate the return speed of the working fluid. - For example, the regulation screw may comprise one first frustoconical operational end in correspondence of the
channel 43 and one second operational end accessible from outside by a user for adjusting the hydraulic damping of the rotation speed of themovable element 10. - According to a preferred but not exclusive aspect of the invention, the
element 110 for adjusting may comprise one adjustingscrew 115, which may be realized according to the teaching of the international patent applicationPCT/IB2014/063556 - In particular, as shown in the
FIG. 6 , thespecial adjusting screw 115 may have a first upper threaded end 116' which may be screwed in one corresponding first upper counterthreaded connecting portion 11' of thehinge body 10 and one secondlower end 116" slidably inserted in one corresponding secondlower guide portion 11" of thehinge body 10. - For this purpose, the second
lower end 116" of thespecial adjusting element 115 may have at least oneportion 117', 117" of theouter surface 118 placed in beat against at least one correspondingportion 12', 12" of theinner surface 12 of the second lower guide portion 11' of thehinge body 10. - In such a way, the vertical slide of the
special adjusting element 115 is always guided, annulling totally the danger of misalignment thereof. - Advantageously, the second
lower end 116" may include onehollow seat 119 for housing one substantiallyfrustoconical seat 120 coaxially inserted therein. - The
special adjusting element 115 may include afirst opening 121 for the inlet/outlet of the working fluid, placed preferably in correspondence with one substantially central portion thereof. - Suitably, the inner surface 122 of the
hollow seat 119 may be towards the external surface 123 of the substantiallyfrustoconical element 120 for defining an interspace fluidically connected to thefirst opening 121 and to thehydraulic circuit 70, and interposed therebetween. - In order to adjust the flow of the working fluid, the interspace may have a variable volume.
- For such purpose, the
hollow seat 12 may have a substantially cylindrical shape, while the substantiallyfrustoconical element 120 may have the end with the smaller diameter towards thefirst opening 121. - In such a way, the reciprocal distancing/approaching of the substantially
frustoconical element 120 and of thespecial adjusting element 115, with the consequent variation of the interspace volume, corresponds to the screwing/unscrewing of the first upper end 116' of thespecial adjusting element 115 from/in the first upper connection portion 11' of thehinge body 10. - This allows to adjust the flow of the working fluid through the
hydraulic circuit 70 in a simple and rapid way, with the maximum guarantee of repeatability over time of the closing element performance during the closing and/or opening movement. - The
special adjusting element 115 allows therefore to adjust the flow of the working fluid through thehydraulic circuit 70, and more in particular in thechannel 43, in a simple and rapid way, with the maximum guarantee of repeatability over time of the closing element performance during the closing and/or opening movement. - According to a different embodiment according to the invention, the damping
elements 40 includes, in addition tochannel 43, also thesecond channel 45, which is provided with anotherinlet 46 in thesecond compartment 19 and one second outlet 46' in thefirst compartment 18. - The first 43 and the
second channel 45 are fluidically independent from each other. In particular, they can fluidically connected only through the variable volume compartments 18, 19. - One of the first and the
second inlet example inlet 44, is fluidically decoupled from the plunger element 50 for the whole stroke thereof in order to let the oil drain away through theinlet 44 itself. The other of the first and thesecond inlet example inlet 46, is fluidically decoupled from the plunger element 50 for a first section of the stroke of the plunger element in order to let the oil drain away and fluidically connected to the plunger element 50 for a second section of the stroke thereof in order to avoiding the outflow of the oil. - In particular, the outer surface 55' of the
cylindrical body 55 can be aimed at capping one of theinlets example inlet 46, to create the coupling of the piston element 50 with the latter and, therefore, in order to avoid the outflow of the oil from thecompartment 19 through thesame inlet 46. - More specifically, as shown for example in
FIGs 2a, 2b and 2c , when the plunger element 50 is in the distal position from thebottom wall 14 of the operating chamber 13 (FIG. 2a ), bothinlets channels FIG. 2c ),inlet 46 ofchannel 45 is coupled with the plunger element 50 so that the oil does not drain away through thechannel 45 itself. - In other words, the oil may drain away through
channels FIG. 2a ) to an intermediate position (FIG. 2b ), and through only one of the two 43, 45 for a second section of its stroke, namely from the intermediate position (FIG. 2b ) to the second end-stroke position (FIG. 2c ). - In this way, the counteraction of the damping
elements 40 can have a different intensity upon the advancement of the plunger element 50 and, more specifically, the counteraction can be higher when the plunger element 50 is in the second section and can be lower when it is in the first section of its stroke, by damping the counter-action itself. - Thanks to this feature, the plunger element 50, and therefore the closing element, can be better braked in the closing phase in proximity to the second end-stroke position of the plunger element itself 50, corresponding to the closed position of the closing element.
- According to a particular aspect of the invention, when the plunger element 50 is in the intermediate position, the
pivot 20 may be rotated by about 20° with respect to the Axis X, preferably about 18°. - The
second channel 45 may have one or several features of one of the above-described embodiments ofchannel 43. In other words, the first andsecond channel - For example, both
channels FIGs. 3a, 3b and 3c ,channels channels - As a possibility, the
helical hollows 47, 47' may have different depths so that the quantity of oil which drains away from therelevant channels - On the other hand, according to a different embodiment shown in
FIGs. 4a, 4b and 4c , one of the twochannels - According to another aspect of the invention, at least one of the
channels element 110 with one or more of the above-described features. - For example, as shown in the
FIGS. 2a, 2b and 2c bothchannels respective adjusting element 110 comprising one adjustingscrew 111 for the flow of the oil. - On the other hand, according to a different embodiment shown in the
FIGS. 5a, 5b and 5c , thechannels first adjusting element 110 comprising the adjustingscrew 111 and onesecond adjusting element 110 comprising thespecial adjusting element 115. - Even though not represented in the annexed figures, each of the
channels element 110, the latter may comprise thespecial regulation element 115. - From the above description, it is evident that the invention fulfils the intended objects.
- The hinge according to the invention is susceptible of numerous modifications and variations as long as they fall within the scope of the appended claims. All the details may be replaced with other technically equivalent elements, and the materials may be different according to requirements, as long as this does not depart from the scope of the invention, which is only defined by the appended claims.
- Although the hinge has been described with particular reference to the annexed figures, the reference numbers used in the description and in the claims are used to improve the intelligence of the invention and do not constitute any limitation to the scope of protection claimed.
