Description
- The present invention relates to a wide opening simplified soft-close hinge.
- Among the many types of hinge, it must be noted that in the furniture production sector, in particular in furniture for caravans, camper vans, boats, road transport vehicles, etc., hinges are known and used for pivoting closing doors of various types of compartment around a horizontal axis. In general, this rotation axis is substantially coincident with the upper side of the door, similar to that used in wall-mounted cabinets or similar.
- Hinges of this type are useful to allow the door to rotate between a closed position of the opening of the compartment, in which it is arranged vertically or tilted towards the furniture and in any case directed downwards, and an open position, in which it is open and moved upward, rotated through an angle of 90° or even greater relative to the preceding closed position.
- In general, these hinges are composed of pairs of four-bar linkages, which on one side have a base element, such as a mounting plate to a fixed part of the structure of the cabinet in which the compartment is provided and a fastening plate to a moving door for closing said compartment. As stated, the aforesaid hinges are such as to be able to pass from a closed configuration to an open configuration in which the fastening plate of the door lies on a different plane relative to the mounting plate of fixed part of the cabinet, when passing from one position to another, due to the rotation of the door through an angle of 90°, or greater than 90°.
- In these arrangements of cabinets or furniture in general, it must be possible to maintain the weight of the rotating door in the open position and it is also necessary to guarantee a more tilted and be able to guarantee a more tilted and recessed correct vertical closed position and for this purpose specific springs are provided.
- These known hinges with opening angle greater than 90° also have some drawbacks, including the complexity of four-bar linkages, the arrangement of the springs with closing with force exerted by the springs with rapid rotation of the door and slamming and risk for the integrity of the cabinet and of the user. The presence of a slow-closing element interposed can improve operation but the complexity of the solution remains. Moreover, the presence of the four-bar linkages makes the assembly cumbersome and difficult to install.
-
JP 2009 121169 A - The general object of the present invention is to produce a wide opening slow-close hinge with a particularly simple construction and with reduced overall dimensions so as to be easy to position.
- Another object of the present invention is to produce a hinge that is capable of solving the aforesaid drawbacks of the prior art in a very simple, economical and particularly functional manner.
- Yet another object of the present invention is to produce a compact hinge, with minimum overall dimensions and which does not require large seats in the cabinet and in the door.
- The aforesaid objects are achieved by a wide opening simplified slow-close hinge according to the independent claim 1 and the following sub-claims.
- The structural and functional features of the present invention and its advantages in relation to the prior art will be even more evident from examination of the following description, referring to the accompanying schematic drawings, which show an example of embodiment of the invention.

Figs. 9, 10 and 11 show side elevation and perspective views of a cabinet with closing door in open position and a side elevation view in closed position of a compartment of the cabinet. - In the following description, to illustrate the figures identical reference numbers are used to indicate constructive elements with the same function. Moreover, for clarity of illustration, some numerical references may not have been repeated in all the figures.
- Indications such as "vertical" and "horizontal" "upper" and "lower" (in the absence of other indications) must be interpreted with reference to the assembly (or operating) conditions and with reference to the normal terminology in use in everyday language, where "vertical" indicates a direction substantially parallel to the direction of the gravitational force vector "g" and horizontal a direction perpendicular thereto.
- With reference to the figures, provided by way of nonlimiting example, these show an embodiment of a wide opening simplified slow-close hinge indicated as a whole with 11 and having an opening angle greater than 90°, as can be seen in the figures.
- The
hinge 11 comprises amounting plate 12 to a fixed part of a cabinet M, such as anupper wall 16 of an internal compartment V of the cabinet M, and afastening plate 14 to a moving part for closing the compartment, such as adoor 15. - In the use of the
hinge 11 in acupboard door 15, for example of a caravan, themounting plate 12 is connected under and inside anupper wall 16 of a fixed part of the cabinet that defines the compartment V subsequently closed by thedoor 15, and thefastening plate 14 is connected inside thedoor 15 that closes the front of the compartment (Figs. 9, 10, 11 ). A connection and fastening of this kind can take place, for example, withconventional screws 17 or other similar threaded fastening members. - Provided between the
mounting plate 12 and thefastening plate 14 are ahinge rotation pin 18 and a snap action and returnpin 19 in the hinge open position, which connect them rotationally and operate them between open and closed position relative to one another. - In particular, the
mounting plate 12 to theupper wall 16 of the fixed part of the cabinet M is provided withholes 20 that receive thefastening screws 17. Moreover, at an end facing themounting plate 12 twoextensions 21 are provided, spaced from each other and directed towards thefastening plate 14. These twoextensions 21 are provided with throughholes 22 aligned with each other to receive therotation pin 18 of the hinge and ends provided with first rounded seats orrecesses 23 to be able to house at least part of the aforesaidsecond pin 19 with hinge in open position, as will be seen below. - In the underneath part thereof, the two
extensions 21 are provided with second rounded seats orrecesses 24 to be able to house the aforesaidsecond pin 19 with hinge in closed position, as will be seen below. - In a central position between the two extensions 21 a blind circular seat 25 is also provided, obtained in the body of the
mounting plate 12, in which a soft-close cylinder 26 with related rod 27 is arranged, directed towards the inside of said seat 25. - The
fastening plate 14 which, as stated, is associated with themounting plate 12, is in turn provided with a pair ofextensions 28, arranged at an end of thefastening plate 14, spaced from each other and facing themounting plate 12. Theextensions 28, which are directed towards themounting plate 12, are such as to be able to be placed side by side with theextensions 21 of themounting plate 12. Theextensions 28 are also provided with throughholes 29 suitable to be placed side by side and aligned with theholes 22 of themounting plate 12 and to receive therotation pin 18 of the hinge. - Between the two
extensions 28 the body of the mounting plate receives and houses acam element 30 for operation of the soft-close cylinder 26. In particular, thiscam element 30 has acam end 31 that faces and coacts with the soft-close cylinder 26. Thiscam element 30 is also provided with athrough hole 32 that receives therotation pin 18 of the hinge followed by a throughslot 33 in which the snap action andreturn pin 19 is arranged, so as to be able to move inside theslot 33. - This snap action and
return pin 19 is also arranged in throughslots 34 obtained on opposite sides of saidfastening plate 14 directly inside the body of thefastening plate 14 upstream of the throughholes 29 obtained in theextensions 28 of thefastening plate 14. - This
cam element 30 is positioned to be able to move forwards and backwards relative to the body of thefastening plate 14 by means of anappendage 35 thereof obtained at the opposite end relative to thecam end 31. Thisappendage 35 is also provided with aslot 36 suitable to receive afastening screw 37 to thefastening plate 14 relative to which theentire cam element 30 is free to move. - Moreover, two return and
stable positioning springs 38 are provided, arranged between theextensions 28 and thecam element 30, at the sides of thecam element 30 and on opposite sides. The twosprings 28 at a first end are housed inside twoblind seats 39 of thefastening plate 14. At the second end thereof, the twosprings 38 are arranged insidecavities 42 of a pair ofpushers 40 provided, at outer ends directed towards themounting plate 12, with rounded seats orrecesses 41, similar and complementary to theseats 23 of theextensions 21 of themounting plate 12, so that they too are able to house at least part of thesecond pin 19. - In the passage from the open configuration (
Figs. 1 to 5 ) to the closed configuration (Figs. 6 to 8 ), the elements of thehinge 11, i.e., the two plates, namely themounting plate 12 and thefastening plate 14, are able to pivot around therotation pin 18. - In the open hinge positions, as can be seen in
Figs. 1 to 5 , thesprings 38 maintain a stable position due to the fact that they thrust thepushers 40 against the snap action and returnpin 19 in the hinge open position. In fact, the rounded seats orrecesses 41 of thepushers 40 house at least one part of the snap action and returnpin 19 so that such position is stably maintained. Thepin 19 is housed at one end of the throughslot 33 and thecam element 30 with thecam end 31 thereof is arranged against, and to coact with, the soft-close cylinder 26, due to therotation pin 18 of thehinge 30. - When wishing to pass to the closed position, rotating the
hinge 11, or thefastening plate 14, around therotation pin 18, the springs exert a return action and thecam end 31 of thecam element 30 acts on the soft-close cylinder 26 which is loaded, causing the return of its rod 27 abutting in the seat 25. - Simultaneously, the snap action and return
pin 19 exits from the first rounded seats orrecesses 23 of the twoextensions 21 of themounting plate 12 and, sliding on the rounded surfaces 13 of theextensions 21, when thedoor 15 of thecabinet 15 rotates, snaps into position in the second rounded seats orrecesses 24 provided in the part underneath the twoextensions 21 of themounting plate 12 and is stably housed therein. - In this way, stable positioning of the closed position, with the
door 15 closing the compartment V of the cabinet M, is achieved. - It must be noted that the
pushers 40 resting on the snap action and returnpin 19, ensure a thrust even if the hinge is not perfectly adjusted. - In fact, on one side the rounded seats or
recesses 41 of thepushers 40 house at least a part of thepin 19 in two spaced positions at the sides of thecam element 30. - On the other side, the snap action and return
pin 19 in turn rests on the two rounded seats orrecesses 23 of the twoextensions 21 of themounting plate 12 in a first position and on the two rounded seats orrecesses 24 provided in the part underneath the twoextensions 21 of themounting plate 12. In any case, the production of a thrust between the parts to ensure optimal operation of the hinge according to the invention is always guaranteed. - This makes it possible to obtain an advantageous and useful arrangement of parts, making the hinge particularly functional, while also being of simple construction and operation.
- All this is achieved in a simple and immediate manner, without slamming, due to the presence of the soft-
close cylinder 26, which dampens the closing force of thesprings 36. - The hinge is particularly compact and simple in construction and has minimum overall dimensions, due to the presence of its two
plates - Advantageously, moreover, plastic materials are widely used to produce the hinge according to the present invention, for example in the
plates cam element 30, in thepushers 40, etc., guaranteed for a wide temperature range and therefore suitable for the specific use, for example, in particular for furniture for caravans, camper vans, boats, road transport vehicles, etc. - The particular arrangement described above allows considerably silent operation, as mentioned without slamming.
- Use with special aluminium profiles, customised for the specific use, must not be excluded.
- It has also been seen, as shown in
Figs. 9 to 11 , that a wide closing angle is possible even for tilting doors like those shown. - In fact,
Fig. 9 shows how thedoor 15 is arranged in the open position supported by the hinge of the present invention. - A minimum force must be used for opening, due to the positioning of the springs, to the shape of the cam element and to the rounded seats provided.
- The weight of this hinge is truly limited, as are its dimensions and the spaces required for its positioning.
- The object set forth in the introduction of the description is thus achieved.
- The scope of protection of the present invention is defined by the appended claims.
