The present invention further relates to a furniture accessory comprising such a braking device; in particular, the present invention relates to a hinge for furniture comprising such a braking device.
In the field of hinges for furniture, the use of braking or damping devices has long been known, said devices pulling to the closing movement of the hinges, thereby braking it or slowing it, movement that is often assisted by a return spring.
In particular, rotary braking devices are known which are applied to or incorporated into the cup body of the hinges and, even more in particular, below the cup body connecting flange. Document WO2008/083417 discloses a rotary braking device according to the preamble of claim 1.

With reference to the accompanying figures, a braking device 10 for the braked movement of two parts of furniture or parts of furniture accessories is shown, which two parts are movable with respect to each other.
In particular, the braking device 10 is applicable to hinges for furniture to brake the closing travel thereof. Even more in particular and as will be described hereinafter, the braking device 10 is applicable to hinges 100 of the type comprising a cup body 101 and a wing body 102 articulated to each other by means of a leverage 103 to brake the closing travel of the wing body 102 on the cup body 101.
The braking device 10 is of the rotary type with rotation axis A.
The braking device 10 essentially serves as a shock absorber.
The braking device 10 comprises:

a first component 11 and a second component 12, which are mounted inside one another in a movable manner with respect to each other around the rotation axis A with the interposition of a viscous medium,
an actuation element 13, which is adapted to be directly or indirectly actuated by one of the two parts of furniture or furniture accessories mutually movable and which is integrally coupled in rotation to the first component 11 at least in the rotation direction of the first component 11 with respect to the second component 12, rotation direction that has to be a braked movement,
a containment body 14 that is fixable to the other one of said two parts of furniture or furniture accessories mutually movable and wherein a housing seat 15 is obtained in which the assembly comprising the second component 12 and the first component 11 mutually assembled is housed, wherein
the second component 12 is elastically yielding, is held tight on the first component 11 and is directly or indirectly coupled to the housing seat 15 in a fixed manner in rotation with respect to the rotation axis A.

Viscous medium means in particular a viscous fluid adapted to exert a braking action between the first component 11 and the second component 12; for example, the viscous fluid is of the silicone-based type known in the field.
The first component 11 and the second component 12 are mounted coaxially to the rotation axis A one inside the other: the first component 11 thus being inside the second component 12.
The first component 11 and the second component 12 comprise each a respective mutual coupling surface, respectively 11a and 12a; when the second component 12 is mounted on the first component 11 and tightened thereon, their mutual coupling surfaces 11a and 12a are facing substantially in mutual contact with interposition of the viscous medium.
At least one of the first component 11 and the second component 12 comprises at least one containment recess 16 for the accumulation therein of the viscous medium, containment recess which is open at the respective mutual coupling surface 11a and 12a.
In greater detail, the first component 11 consists of a hollow cylindrical body advantageously open at one or both axial ends thereof, at each of which it has a respective flange 11b.
The lateral outer surface of the hollow cylindrical body defines the mutual coupling surface 11a with the second component 12.
The lateral inner surface of the hollow cylindrical body, instead, defines a coupling surface 11c with the actuation element 13 by means of the unidirectional or freewheel coupling mechanism 17 described hereinafter.
The second component 12 is elastically yielding and, in particular, is made of elastically yielding material, such as an elastomer, for example a thermoplastic elastomer (TPE) or a nitrile rubber (NBR).
The second component 12 consists of an annular element made of elastically yielding material.
The lateral inner surface of this annular element defines the mutual coupling surface 12a with the mutual coupling surface 11a of the first component 11. The annular element forming the second component 12 is in fact mounted on the hollow cylindrical body that forms the first component 11.
The annular element forming the second component 12 is sized in such a way as to be contained between the two flanges 11b of the first component 11 and to be tightened or clamped on the lateral outer surface of the hollow cylindrical body forming the first component 11.
In particular, the inner diameter of the annular element forming the second component 12 is substantially equal to or, preferably, slightly smaller, for example by a few tenths of a millimetre, than the outer diameter of the hollow cylindrical body forming the first component 11 so that, in the mounting configuration of the one on the other, the second component 12 surrounds the first component 11 and their mutual coupling surfaces 12a and 11a are mutually facing and in close contact against each other.
However, the inner diameter of the annular element forming the second component 12 may be slightly greater, for example by a few tenths of a millimetre, than the outer diameter of the hollow cylindrical body forming the first component 11 so that, in the mounting configuration of the one on the other, the second component 12 surrounds the first component 11 and their mutual coupling surfaces 12a and 11a are mutually facing and substantially in contact with a possible clearance, of the order of a few tenths of a millimetre.
The mounting of the second component 12 onto the first component 11 is in any case made possible by the elasticity of the second component 12.
As shown in figure 2B, the containment recess 16 in which the viscous medium is accumulated is formed in the second component 12 and is open at the mutual coupling surface 12a thereof formed by the lateral inner surface of the annular element forming the second component 12 itself.
In the embodiment shown, the containment recess 16 consists of a circumferential groove with a wavy pattern; as is easily understood by those skilled in the art, the containment recess 16 may have different shapes than the one shown, for example being discontinuous or comprising a plurality of slits with different shape.
It is noted that the viscous medium is interposed between the whole mutual coupling surfaces 11a and 12a of the first component 11 and of the second component 12 and is not only present in the containment recess 16; the containment recess 16 in fact acts as a reservoir of the viscous medium.
The assembly comprising the second component 12, the first component 11 and the actuation element 13 mutually assembled is inserted into the housing seat 15. The direct or indirect coupling between this assembly and the housing seat 15 is configured to fasten the second component 12 onto the containment body 14, in particular to prevent the rotation thereof around the rotation axis A.
In a possible embodiment, the second component 12 and the housing seat 15 are configured and sized to be coupled directly to each other with a forced interference and/or shape coupling configured to prevent the relative rotation of the second component 12 with respect to the containment body 14 around the rotation axis A and possibly tighten (press) the second component 12 on the first component 11.
In a possible alternative embodiment, advantageously preferred, the coupling between the housing seat 15 and the second component 12 is of an "indirect" type (i.e., through a further component) and is, for example, implemented by means of an elastic gripper 18.
In this case, the elastic gripper 18 and the housing seat 15 are configured and sized to be coupled directly to each other with a forced interference and/or shape coupling that is adapted to tighten (press) or hold tightened the elastic gripper 18 on the second component 12 (which is thus tightened on the first component 11) and to prevent the relative rotation of the elastic gripper 18 (and, with the latter, of the second component 12 tightened therein) with respect to the containment body 14 around the rotation axis A.
With reference to the embodiment shown in the accompanying figures, the elastic gripper 18 is mounted on the assembly comprising the second component 12, the first component 11 and the actuation element 13 assembled to each other with the interposition of the unidirectional or freewheel coupling mechanism 17.
The elastic gripper 18 comprises a disc-shaped body 19 crossed by a central hole 20 for the passage of a portion of the actuation element 13 therethrough.
A plurality of arms 21 or wings extend from the outer peripheral edge of the disc-shaped body 19 in a direction substantially parallel to the axis of the central hole 20. The arms 21 are mutually spaced apart along the outer peripheral edge of the disc-shaped body 19. The volume delimited by the disc-shaped body 19 and by the arms 21 defines a seat for the assembly comprising the second component 12, the first component 11 and the actuation element 13 assembled to each other with the interposition of the unidirectional or freewheel coupling mechanism 17. The arms 21 are shaped and arranged so as to be elastically fastened onto this assembly and in particular onto the second component 12 after the coupling of the elastic gripper 18 with the housing seat 15.
Advantageously, the arms 21 have the respective inner face arched concave.
The coupling between the elastic gripper 18 and the housing seat 15 is of a forced type by interference and/or shape configured to prevent the relative rotation around the rotation axis A of the elastic gripper 18 and of the second element 12 therewith, with respect to the containment body 14.
In the embodiment shown in the accompanying figures, the lateral wall delimiting the housing seat 15 has a plurality of lowered seats 22 each of which is adapted to receive a respective arm 21 so as to implement a prismatic coupling.
The coupling between the elastic gripper 18 and the housing seat 15 is slightly forced with a desired interference so that the elastic gripper 18 is tightened on the second component 12. The elastic gripper 18 thus tightens the second component 12 on the first component 11 and retains the second component 12 fixed in rotation with respect to the containment body 14 while the first component 11 can rotate with respect to the second component 12.
As mentioned above, the actuation element 13 is coupled to the first component 11 in a rotatable manner around the rotation axis A by means of a unidirectional or freewheel coupling mechanism 17 that is configured to block the actuation element 13 integrally in rotation to the first component 11 in the direction of the rotation of the first component 11 with respect to the second component 12, rotation direction that has to be of braked movement and to leave the actuation element 13 free to rotate with respect to the first component 11 in the opposite direction of rotation. When the rotation imposed to the actuation element 13 by one of the two parts of a furniture or a furniture accessory mutually movable takes place in the direction that must have a braked movement, the unidirectional or freewheel coupling mechanism 17 integrally couples in rotation the actuation element 13 and the first component 11. The rotation of the actuation element 13 is thus transmitted to the first component 11, which rotates in a braked manner with respect to the second component 12 which is instead fixed, via the containment body 14, to the other of the two parts of a furniture or furniture accessory mutually movable. The relative movement between the two parts of a furniture or a furniture accessory is thus braked, slowed down or dampened.
When the rotation imposed to the actuation element 13 by one of the two parts of a furniture or a furniture accessory mutually movable takes place in the direction opposite to that of the movement that must be braked, the unidirectional or freewheel coupling mechanism 17 uncouples the actuation element 13 from the first component 11, thus allowing the free rotation of the first one with respect to the second one. In this case, the rotation of the actuation element 13 is not transmitted to the first component 11, which remains stationary. The relative movement between the two parts of a furniture or a furniture accessory is thus free, i.e. not braked.
The actuation element 13 consists of a pin that is coaxially mounted to the rotation axis A. The pin 13 has a first portion 13a and a second portion 13b along its longitudinal development which are defined close to the opposite ends thereof. The first portion 13a is configured to interact directly or indirectly with one of the two parts of a furniture or furniture accessory mutually movable at least during the movement that must be braked. In particular, the first portion 13a can be integrally coupled in rotation with a lever or other actuation element on which one of the two parts of a furniture or furniture accessory mutually movable acts. Advantageously, the first portion 13a can be integrally coupled in rotation with a lever or other actuation element by means of a prismatic coupling.
The second portion 13b is instead inserted in the first component 11 with the interposition of the unidirectional or freewheel coupling mechanism 17.
The latter in particular comprises:

a first surface 17a integral with the first component 11,
a second surface 17b integral with the actuation element 13 and facing the first surface 17a so as to define an empty space therewith, and
at least one fastening element 23 which is housed in this empty space,

first surface

second surface

fastening element

actuation element

In particular, the profile of the first surface 17a and/or of the second surface 17b has a profile such as to delimit a channel which, in the direction of rotation which must have a braked movement, it is shaped to shrink to a dimension smaller than that of the fastening element 23.
With particular reference to the embodiment shown in the accompanying figures, the first surface 17a coincides with the lateral inner surface 11c of the first component 11 which is cylindrical with a circular section.
The second surface 17b is defined by the lateral outer surface of the second portion 13b of the pin that forms the actuation element 13. Such a second surface 17b has an alternation of arched portions with non-constant curvature radius along their development so as to define lobes, each of which cooperating with a respective fastening element 23 consisting of a cylindrical roller.
The cylindrical rollers forming the fastening elements 23 are held mutually spaced apart by a cage 24 coaxial to the pin forming the actuation element 13.
The containment body 14 also has attachment means 25 for attaching to one of the two mutually movable parts of a furniture or furniture accessory.
The containment body 14 is advantageously shaped so as to fit to the part on which it is to be mounted.
To those skilled in the art, the assembly and operation of the braking device 10 according to the present invention are apparent in the light of the accompanying figures and of the above description.
The second component 12 is mounted onto the first component 11 with the interposition of the viscous medium; in particular, the viscous fluid is distributed onto the lateral outer surface of the first component 11 onto which the second component 12 is then mounted.
The actuation element 13 is mounted into the first component 11 with the interposition of the unidirectional or freewheel coupling mechanism 17. The elastic gripper 18 is then mounted onto the assembly thus formed, in such a way that the first end 13a of the actuation element 13 protrudes from the central hole 20 thereof.
The assembly thus formed is inserted into the housing seat 15. The interference between the elastic gripper 18 and the housing seat 15 is such as to tighten the first on the second component 12, which is thus tightened (pressed or compressed) on the first component 11 and held fixed in rotation around the containment body 14.
The braking device 10 thus assembled forms a unified assembly that can be easily mounted onto one of the two mutually movable parts of furniture or furniture accessory.
As indicated above, the braking device 10 is of the type especially adapted to be mounted on a hinge 100 for furniture as shown in figures 4 to 7 and 10 to 12.
The hinge 100 comprises, in a known manner, a cup body 101 and a wing body 102 that are articulated to each other by means of a forming leverage 103, such as a single or a double articulated quadrilateral.
In the embodiment shown in the accompanying figures, the leverage 103 comprises a first connecting rod 104 and a second connecting rod 105, each of which has one end articulated to the wing body 102 and the opposite end articulated to the cup body 101 so as to define an articulated quadrilateral with articulation axes B1, B2, B3 and B4.
The cup body 101 can be fixed to a fixed part of a piece of furniture and the wing body 102 can be fixed to a wing of the furniture.
The braking device 10 is mounted on the hinge 100 to brake the closing travel of the wing body 102 on the cup body 101.
In particular, the braking device 10 is mounted on the cup body 101 and, advantageously, outside of it.
In greater detail, the cup body 101 comprises a bottom 106 that is joined to a lateral wall 107 which at the end opposite the bottom 106 is in turn joined to a flange 108.
The braking device 10 is arranged outside the lateral wall 107 and below the flange 108 so that the rotation axis A is parallel to the articulation axes B1-B4 of leverage 103.
The lateral wall 107 has an opening 109 through which the first portion 13a of the actuation element 13 protrudes into the cup body 101 to interfere directly or indirectly with a component of leverage 103 during the rotation of the wing body 102 with respect to the cup body 101 in the closing direction of hinge 100.
In particular, the hinge 100 comprises an actuation lever 110 which is mounted on the first portion 13a of the actuation element 13 integral thereto in rotation through a prismatic coupling. The actuation lever 110 is accommodated in the cup body 101 and has a contact portion 111 configured and arranged to interfere with the back of the second connecting rod 105 at least during the closing direction of rotation of the wing body 102 with respect to the cup body 101.
The actuation element 13 therefore interferes indirectly with the second connecting rod 105 through the actuation lever 110.
The hinge 100 further comprises a return or reset device 200 of the actuation lever 110.
The return device 200 is also mounted on the cup body 101. The return device 200 is arranged below the flange 108 and outside the lateral wall 107 opposite the braking device 10.
The return device 200 comprises a containment shell 201 that is fixable to the cup body 101 and in which a cavity 202 is formed for containing an elastic return element 203 of a rotor accommodated therein, rotatably around a rotation axis C.
The elastic return element 203 consists of a torsion helical spring that has one end attached to the containment shell 201 and the opposite end attached to the rotor.
The rotor consists of a bushing 204 in which the end 205a of a pin 205 is inserted by interlocking, which pin at the opposite end is provided with a shaped portion 205b which is configured to couple to the actuation lever 110 so as to be integral thereto in rotation, for example with a prismatic coupling.
A cover 206 closes the cavity 202, thus retaining the elastic return element 203 and the rotor therein. The cover 206 is crossed by a central hole 207 through which the shaped portion 205b protrudes, shaped portion that is adapted to couple with the actuation lever 110.
A projection 208 is obtained inside the cover 206 onto which an appendage 209 of the rotor abuts to impart a desired degree of preload to the elastic return element 203.
A further opening 112 is obtained on the lateral wall 107 of the cup body 101, through which opening the shaped portion 205b protrudes into the cup body 101.
The openings 109 and 112 face each other so that the braking device 10 and the return device 200 can be mounted with the rotation axis A of the actuation element 13 and the rotation axis C of the rotor mutually coincident.
The actuation lever 110 is C- or U-shaped or the like and comprises a pair of ears 113 in each of which a shaped hole is formed, adapted to couple with a shape coupling with the first portion 13a of the actuation element 13 and with the shaped portion 205b of pin 205, respectively.
The two ears 113 are joined by a bridge 114 which defines the contact portion 111 that interferes with the back of the second connecting rod 105.
A protection body 300 is mounted on the contact portion 111 which is the object of a separate and simultaneous patent application in the name of this same applicant.
To those skilled in the art, the assembly and operation of the hinge 100 are immediately apparent in the light of the accompanying figures and of the above description.
When the hinge 100 is in open configuration, the actuation lever 110 is arranged in a first position in which the contact portion 111 thereof is spaced from the bottom 106.
During the closing step of the hinge 100, the second connecting rod 205 exerts a thrust on the actuation lever 110 such as to cause the rotation thereof around the rotation axis A/C in the direction according to that of rotation of the second connecting rod 105 itself and indicated by arrow V1 in the accompanying figures 11 and 12.
The rotation of the actuation lever 110 in direction V1 which is as the one of closing of the wing body 102 on the cup body 101 is transmitted to the braking device 10 and to the return device 200.
The braking device 10 is configured and arranged to brake and slow down the closing movement of the hinge 100. During this same movement, the elastic return element 203 of the return device 200 is instead placed under tension.
In particular, the braking device 10 is configured and arranged so that the rotation of the actuation element 13 in direction V1 which is as the direction of rotation that allows coupling the actuation element 13 integrally in rotation to the first component 11 by means of the unidirectional or freewheel coupling mechanism 17. The fastening elements 23 are interlocked between the first surface 17a and the second surface 17b, making them mutually integral.
The actuation element 13, which is set in rotation by the actuation lever 110, pulls the first component 11 in rotation with respect to the second component 12 that is instead fixed with respect to the containment body 14, in turn constrained to the cup body 101.
The viscous medium interposed between the first component 11 and the second component 12 brakes, slows down or otherwise "damps" the relative rotation thereof and thus the closing movement of the hinge.
When the hinge 100 is completely closed, the actuation lever 110 is in a second position in which the contact portion 111 thereof is close to bottom 106.
In the opposite direction of rotation to open the hinge 100 (indicated by arrow V2 in figures 11 and 12), the reset device 200 returns the actuation lever 110 to the first position, while the action of the braking device 10 is null. The unidirectional or freewheel coupling mechanism 17 in fact allows the free rotation of the actuation element 13 in the opposite direction V2.
The braking device according to the present invention has the advantage that it can be assembled quickly and easily to form a unitary body which, in turn, can be quickly and easily mounted on pieces of furniture or furniture accessories and, in particular, cabinet hinges.
The braking device according to the present invention allows introducing the viscous medium between the mutually movable components thereof during their assembly, without the need to introduce it under particular pressure or temperature conditions.
Particularly advantageous is the embodiment in which the second component made of elastically yielding material is mounted on the first component with a defined and desired clearance and only later tightened (pressed) thereon, for example by means of the elastic gripper and/or the coupling with the housing seat of the containment body. In this case, in fact, the insertion of the viscous medium is particularly simple and easy.
Even more advantageous is the embodiment that provides for the use of the elastic gripper that tightens the second component on the first component directly or after the coupling with the housing seat of the containment body. In this case, in fact, at the time of the coupling with the containment body, any sliding movements of the second component in the housing seat itself and which could destabilize its coupling on the first component, resulting in loss of viscous medium, are excluded.
In addition, the viscous medium is contained between the two mutually movable components of the braking device, held the one tightened on the other, without the need to use any special additional seals.
The braking device and the hinge for furniture comprising such a braking device thus conceived are susceptible to several changes and variations, all falling within the invention, as defined by the appended claims.
