Definitions
- the present invention relates to a concealed hinge for doors or windows, such as for example reinforced doors, shutters and windows.
- concealed hinges are used which, when the door or window is in the closed condition, are completely hidden inside the frame or case of the door or window and/or within the leaf thereof.
- hinges which comprise a bridge constituted by two profiles that are approximately L-shaped in plan view and are mutually connected so as to form as a whole an approximately U-shaped plan configuration, so as to form an approximately flat base from which two approximately mutually parallel arms protrude.
- One of the two arms of the bridge is fixed by means of its outer lateral surface to the lateral edge of the leaf of the door or window, while the other arm is hinged to a vertical hingeing pivot arranged within an appropriately provided seat formed in the frame or border of the door or window.
- the configuration and arrangement of the seat and of the bridge are such that the latter is completely concealed within such seat when the door or window is in the closed condition.
- this known type of hinge has a drawback: it in fact allows to turn the leaf of the door or window with respect to the frame or case by an angle that can be at the most slightly greater than 90°; therefore, this known type of hinge does not allow to arrange the leaf of the door or window parallel to the plane of arrangement of the frame or case thereof and therefore does not allow to utilize the entire space of the opening with which the door or window is associated.
- EP 1835099 discloses a hinge, particularly for a door, particularly of the reinforced type, or for a shutter, which is constituted by two or more arc-like elements that are shaped approximately like an annular sector in plan view and are mutually stacked and slidingly associated, such two or more arc-like elements having means designed to limit their mutual sliding between a closed condition, in which they are approximately exactly superimposed on each other, and an open condition, in which they are mutually offset, so as to define as a whole, in plan view, an angle that can vary from approximately 180° to approximately 360°.
- Two or more of such hinges can be associated with a door or shutter by fixing the arc-like element arranged in an upper position with respect to the other ones within an appropriately provided seat formed in one of the sides of a door or shutter that constitutes a door or window, and by fixing the arc-like element arranged in a lower position with respect to the other ones in an opening provided in a post of the frame or case of such door or window.
- the aim of the present invention is to solve the above-mentioned technical problems, eliminating the drawbacks of the cited background art, by providing an invention that allows to obtain a concealed hinge for doors or windows that allows to obtain a rotation of the leaf of a door or window even through 180° with respect to the closed condition thereof, so as to be able to utilize the entire space of the opening with which the door or window is associated.
- an object of the invention is to provide a concealed hinge for doors or windows that has a reduced cost.
- a concealed hinge for doors or windows constituted by a frame or case with which at least one leaf is rotatably associated, said hinge comprising a bridge that is approximately U-shaped in plan view so as to form a base from which a first arm and a second arm protrude which are approximately mutually parallel, characterized in that said first and second arms each interact selectively and respectively with first and second snap-acting means that are designed to guide the opening of said leaf from a closed condition to a first stable condition rotated through approximately 90°, followed by a second stable condition rotated through approximately 90° more, and vice versa.
- the reference numeral 1 designates a concealed hinge for doors or windows 2, such as for example a reinforced door, which are constituted by a box-like frame or case 3 with which at least one box-like leaf 4 is rotatably associated.
- the hinge 1 comprises a bridge 5, which is provided preferably monolithically and is approximately U-shaped in plan view, so as to form a base 6 from which a first arm 7 and a second arm 8, which are approximately mutually parallel, protrude.
- first arm 7 and the second arm 8 have approximately the same length and their ends lie on planes that are perpendicular to such first and second arms and are mutually parallel.
- the base 6 of the bridge 5 has a first portion 6a, which is inclined so as to form an acute angle, considering as positive a counterclockwise rotation with respect to the first arm 7.
- a second portion 6b which is approximately perpendicular to the second arm 8 and is connected thereto, is contiguous to such first portion.
- the end of the first arm 7 is or can be hinged about a first vertical hingeing axis that lies within an appropriately provided first seat 9 that is formed axially within a post 10 of the frame or case 3.
- the first arm 7 has, at its free end, a cylindrical tab 24, which lies at right angles to the first arm 7 for at least part of its height and protrudes below it, so that it is inserted rotatably in an appropriately provided cavity, not shown in the accompanying figures, which is formed axially with respect to a first supporting element 25 that is or can be fixed within the first seat 9 formed in the frame or case 3, so as to allow to couple rotatably the first arm 7 to the first seat 9.
- the longitudinal axis of the cylindrical tab 24 therefore constitutes the first hingeing axis with respect to which the first arm 7 of the bridge 5 is hinged.
- the end of the first arm 7 is arranged adjacent to a first wall 16 of the first seat 9, which, in the condition in which the leaf 4 is closed, is arranged approximately parallel to an internal lateral surface 4a of the leaf 4, the base 6 protruding outside the post 10, in the direction of a lateral surface 13 of the adjacent leaf 4, through an appropriately provided opening 16a.
- a rotation of approximately 90° with respect to the post 10 is thus allowed to the first arm 7.
- the end of the second arm 8 is or can be hinged at a second vertical hingeing axis to a pivot 14, which is arranged and coupled within a second seat 12 formed within the at least one leaf 4 in a region that is adjacent to the facing lateral surface 13, that faces, when the leaf 4 is in the closed condition, the first seat 9 of the frame or case 3.
- the pivot 14 is associated at a corner of a supporting plate 15 that is approximately U-shaped in plan view and is shaped approximately partially complementarily with respect to the second seat 12 and is fixed inside it, for example by welding or adhesive bonding.
- the pivot 14 protrudes from a second supporting element 35, which is or can be fixed to the supporting plate 15.
- An access opening 15a for the end of the second arm 8 is provided on the supporting plate 15 at the pivot 14 and is shaped advantageously so as to form an eye 8a for rotary interconnection to the pivot 14.
- the axis of the pivot 14 thus constitutes the second hingeing axis for the second arm 8 of the bridge 5.
- the end of the second arm 8 is arranged adjacent to a second wall 15b of the supporting plate 15 that is adjacent to the internal lateral surface 4a of the leaf 4, the base 6 protruding outside it through the access opening 15a formed on the supporting plate 15, and a corresponding slot, not shown in the accompanying figures, which is provided on the lateral surface 13 of the leaf 4.
- the leaf 4 is therefore allowed to rotate of approximately 90° with respect to the second arm 8.
- the first arm 7 interacts with first snap-acting means, which are adapted to block removably the rotation of the bridge 5 with respect to the first axis of rotation when a first stable condition rotated through approximately 90°, shown in Figure 5 , is reached starting from the closed condition of the leaf 4, shown in Figure 4 .
- such first snap-acting means comprise a first spring 26, conveniently of the leaf spring type, which is constituted by an elastically deformable metallic lamina that has a first wing 27 and a second wing 28, which are approximately flat, are mutually connected by an oblique portion 29, and lie, in the non-deformed condition of the first spring 26, on two planes that are approximately mutually parallel and spaced.
- the first wing 27 of the first spring 26 is fixed jointly to the first wall 16 of the first seat 9, while the second wing 28 abuts against the lateral surface of the cylindrical tab 24.
- a first slot 30 is provided on the lateral surface of the cylindrical tab 24 and has such a shape that it can accommodate at least partially inside it the second wing 28 of the first spring 26.
- the shape and arrangement of the cylindrical tab 24 of the first slot 30, and of the first spring 26 are such that starting from the closed condition of the leaf 4 and upon a rotation of the leaf 4, the second wing 28 abuts against the region of the lateral surface of the cylindrical tab 24 that is not affected by the first slot 30 and is thus deformed elastically toward the first wall 16 of the first seat 9.
- the first snap-acting means adapted to block removably the rotation of the bridge 5 with respect to the first rotation axis, upon reaching, starting from the closed condition of the leaf 4 shown in Figure 9 , a first stable condition rotated through approximately 90° shown in Figure 10 , are instead constituted by a shaft 40, which is jointly connected for rotation to the cylindrical tab 24 and protrudes axially with respect to it; in the part of the shaft 40 that is external to the tab 24, two pins 41 a, 41b protrude radially and along a diametrical axis and slide on a lateral surface 42, which is shaped according to an inclined plane that is preferably helical so as to keep the door always at the same distance from the ground, of a bush 43 that is jointly connected to the first supporting element 25 that is or can be fixed within the first seat 9 provided in the frame or case 3.
- the pins 41 a, 41b are forced to disengage the seats 44 and move on the lateral surface 42 until they again engage further seats 44 after a rotation through 90°, so as to reach a stable position.
- the second arm 8 interacts with second snap-acting means, which are adapted to block removably the rotation of the bridge 5 with respect to the second axis of rotation, starting from the closed condition of the leaf 4, shown in Figure 4 , until such first stable condition rotated through approximately 90°, shown in Figure 5 , is reached.
- such second snap-acting means comprise a second spring 31, conveniently of the helical type, which is inserted in an appropriately provided receptacle 32 that is formed axially with respect to an appropriately provided support 33 that is or can be fixed at least partially within the second seat 12 approximately parallel to the internal lateral surface 4a, with the free end directed toward the access opening 15a.
- a ball 34 protrudes partially from the support 33 by way of the action of the thrust applied by the second spring 31 and abuts against the lateral surface of the eye 8a provided at the free end of the second arm 8; advantageously, a second slot 36 is provided on the lateral surface of the eye 8a and has such a shape that it can at least partially accommodate inside it the ball 34.
- the shape and position of the eye 8a, of the second slot 36, of the support 33 and of the ball 34 are such that starting from the closed condition of the leaf 4 and up to the first stable condition rotated through approximately 90°, shown for example in Figure 5 , the ball 34 is kept pressed by the second spring 31 within the second slot 36, so as to prevent the rotation of the eye 8a, and therefore of the bridge 5, with respect to the support 33 and therefore with respect to the second seat 12.
- the second arm 8 is jointly connected for rotation to the leaf 4.
- the concealed hinge 1 comprises means designed to maintain alignment with one or more additional hinges 1 associated with a same door or window 2; as shown for example in Figures 7 and 8 , such means can be constituted by a straight torsion bar 20, to the lateral surface of which respectively the first arms 7 or the second arms 8 of the bridges 5 of the various hinges 1 associated with a same door or window 2 are fixed, for example by welding.
- the torsion bar 20 coincides with the eye 8a provided at the free end of the second arm 8 of the bridge 5 of various mutually connected hinges 1 (only one of which is shown in Figures 7 and 8 ).
- torsion bar 20 causes the bridges 5 of the various hinges 1 to all rotate synchronously with respect to each other, thus preventing the leaf 4 with which the hinges 1 are associated from being able to tilt abnormally.
- the torsion bar 20 can be fixed to the second arms 8 of the bridges 5 of two or more separate hinges 1 associated with a same door or window 2; in this case, the torsion bar 20 has a hollow tubular structure, so that it can accommodate, at its free ends, two pivots 14 that protrude from the two second supporting elements 35 that are or can be associated jointly within the frame or case 3, together with the torsion bar 20, so as to achieve the hingeing of the leaf 4 to the frame or case 3.
- the longitudinal axis of the torsion bar 20 constitutes the second hingeing axis of the bridges 5.
- the torsion bar 20 can be fixed to the first arms 7 of the bridges 5 of multiple separate hinges 1 associated with a same door or window 2; as an alternative, two separate torsion bars 20 can be fixed respectively to the first arms 7 and to the second arms 8 of multiple separate hinges 1 associated with a same door or window 2.
- the torsion bar 20 can be constituted by a solid rod, and it is possible to provide, for example by turning, at the ends of such rod, second pivots with which appropriately provided supports, again not illustrated, are rotatably associable, such supports being jointly associated or associable respectively within the frame or case 3 and/or within the leaf 4, depending on whether the torsion bar 20 is associated with the first and/or second arms of the bridges 5 of the connected hinges 1 of the torsion bar 20.
- the torsion bar 20 can be made of a desired material, such as for example steel, carbon fiber, the material known by the trademark KEVLAR, fiberglass.
- the second snap-acting means which are adapted to block removably the rotation of the bridge 5 with respect to the second rotation axis, starting from the closed condition of the leaf 4, shown in Figure 9 , until such first stable condition rotated through approximately 90°, shown in Figure 10 , is reached, comprise a cylinder 45, which protrudes at right angles from the end of the second arm 8 in the opposite direction with respect to the pivot 14, a diametrical slot 46 being obtained at the free end of the cylinder 45 and acting as a seat for the rotary interconnection of a wheel 47 that is pivoted to the cylinder by means of a pivot 48.
- the first spring 26, conveniently of the leaf spring type, interacts with the rolling surface of the wheel 47 and is constituted by an elastically deformable metallic lamina that has the first wing 27 and the second wing 28, which are approximately flat, are mutually connected by the oblique portion 29 and lie, in the non-deformed condition of the first spring 26, on two planes which are approximately parallel and spaced with respect to each other.
- the first wing 27 of the first spring 26 is monolithic with a U-shaped support 49, which is jointly connected at its ends to a cover 50, which in turn is jointly connected to the first wall 16 of the second seat 12, while the second wing 28 abuts against the rolling surface of the wheel 47.
- the hinge 1 comprises stroke limiting means for the rotation of the leaf 4 with respect to the second axis of rotation, which are constituted advantageously by an abutment element 23 that is preferably approximately L-shaped in plan view and is fixed to the edge of the leaf 4 that is contiguous to the frame or case 3 in the condition in which the leaf 4 is fully open; the abutment element 23 abuts, in the maximum allowed opening condition of the leaf 4, against the second portion 6b of the base 6 of the bridge 5, so as to stop the rotation of the leaf 4 with respect to the second rotation axis.
- an abutment element 23 that is preferably approximately L-shaped in plan view and is fixed to the edge of the leaf 4 that is contiguous to the frame or case 3 in the condition in which the leaf 4 is fully open; the abutment element 23 abuts, in the maximum allowed opening condition of the leaf 4, against the second portion 6b of the base 6 of the bridge 5, so as to stop the rotation of the leaf 4 with respect to the second rotation axis.
- first and second snap-acting means can be replaced with other mechanical means adapted to allow selective positioning among the elements.
- two or more hinges 1 can be associated with a door or window 2, so as to hinge the leaf 4 to the frame or case 3 of the latter.
- the leaf 4 By imparting a rotation to the leaf 4 in the direction for opening it, the leaf 4 rotates with respect to the first rotation axis until it reaches the first stable condition rotated through approximately a further 90°, shown in Figure 5 , and the second wing 28 of the first spring 26 enters elastically the first slot 30, thus blocking the further rotation, in the same direction, of the first arm 7 with respect to the first rotation axis.
- the leaf 4 can be turned until it is arranged in a second stable condition that is rotated through approximately a further 90°, in which it is therefore substantially parallel to the plane of arrangement of the frame or case 3, thus allowing to utilize the entire space of the opening.

Abstract
Description
- The present invention relates to a concealed hinge for doors or windows, such as for example reinforced doors, shutters and windows.
- Currently, in order to improve the overall aesthetics of doors or windows, particularly in the closed condition, and to make it more difficult to tamper with them, so-called concealed hinges are used which, when the door or window is in the closed condition, are completely hidden inside the frame or case of the door or window and/or within the leaf thereof.
- For example, hinges are known which comprise a bridge constituted by two profiles that are approximately L-shaped in plan view and are mutually connected so as to form as a whole an approximately U-shaped plan configuration, so as to form an approximately flat base from which two approximately mutually parallel arms protrude.
- One of the two arms of the bridge is fixed by means of its outer lateral surface to the lateral edge of the leaf of the door or window, while the other arm is hinged to a vertical hingeing pivot arranged within an appropriately provided seat formed in the frame or border of the door or window.
- The configuration and arrangement of the seat and of the bridge are such that the latter is completely concealed within such seat when the door or window is in the closed condition.
- However, this known type of hinge has a drawback: it in fact allows to turn the leaf of the door or window with respect to the frame or case by an angle that can be at the most slightly greater than 90°; therefore, this known type of hinge does not allow to arrange the leaf of the door or window parallel to the plane of arrangement of the frame or case thereof and therefore does not allow to utilize the entire space of the opening with which the door or window is associated.
- As a partial solution to this drawback,
EP 1835099 is also known which discloses a hinge, particularly for a door, particularly of the reinforced type, or for a shutter, which is constituted by two or more arc-like elements that are shaped approximately like an annular sector in plan view and are mutually stacked and slidingly associated, such two or more arc-like elements having means designed to limit their mutual sliding between a closed condition, in which they are approximately exactly superimposed on each other, and an open condition, in which they are mutually offset, so as to define as a whole, in plan view, an angle that can vary from approximately 180° to approximately 360°. - Two or more of such hinges can be associated with a door or shutter by fixing the arc-like element arranged in an upper position with respect to the other ones within an appropriately provided seat formed in one of the sides of a door or shutter that constitutes a door or window, and by fixing the arc-like element arranged in a lower position with respect to the other ones in an opening provided in a post of the frame or case of such door or window.
- With the door or shutter in the closed condition, all the arc-like elements are exactly mutually superimposed and the hinge is completely concealed from sight; by turning the door or shutter in the direction for opening it, the various arc-like elements slide on each other and allow to obtain a rotation of the door or shutter of even 180° with respect to when it is in the closed condition, thus allowing full utilization of the space of the opening with which such door or shutter is associated.
- Although this solution solves the drawbacks noted above, it has a high constructive complexity and a high cost.

- With reference to the figures, the
reference numeral 1 designates a concealed hinge for doors orwindows 2, such as for example a reinforced door, which are constituted by a box-like frame orcase 3 with which at least one box-like leaf 4 is rotatably associated. - The
hinge 1 comprises abridge 5, which is provided preferably monolithically and is approximately U-shaped in plan view, so as to form abase 6 from which afirst arm 7 and asecond arm 8, which are approximately mutually parallel, protrude. - Advantageously, the
first arm 7 and thesecond arm 8 have approximately the same length and their ends lie on planes that are perpendicular to such first and second arms and are mutually parallel. - The
base 6 of thebridge 5 has afirst portion 6a, which is inclined so as to form an acute angle, considering as positive a counterclockwise rotation with respect to thefirst arm 7. - A
second portion 6b, which is approximately perpendicular to thesecond arm 8 and is connected thereto, is contiguous to such first portion. - The end of the
first arm 7 is or can be hinged about a first vertical hingeing axis that lies within an appropriately providedfirst seat 9 that is formed axially within apost 10 of the frame orcase 3. - Advantageously, the
first arm 7 has, at its free end, acylindrical tab 24, which lies at right angles to thefirst arm 7 for at least part of its height and protrudes below it, so that it is inserted rotatably in an appropriately provided cavity, not shown in the accompanying figures, which is formed axially with respect to a first supportingelement 25 that is or can be fixed within thefirst seat 9 formed in the frame orcase 3, so as to allow to couple rotatably thefirst arm 7 to thefirst seat 9. - The longitudinal axis of the
cylindrical tab 24 therefore constitutes the first hingeing axis with respect to which thefirst arm 7 of thebridge 5 is hinged. - The end of the
first arm 7 is arranged adjacent to afirst wall 16 of thefirst seat 9, which, in the condition in which theleaf 4 is closed, is arranged approximately parallel to an internallateral surface 4a of theleaf 4, thebase 6 protruding outside thepost 10, in the direction of alateral surface 13 of theadjacent leaf 4, through an appropriately provided opening 16a. - A rotation of approximately 90° with respect to the
post 10 is thus allowed to thefirst arm 7. - The end of the
second arm 8 is or can be hinged at a second vertical hingeing axis to apivot 14, which is arranged and coupled within asecond seat 12 formed within the at least oneleaf 4 in a region that is adjacent to the facinglateral surface 13, that faces, when theleaf 4 is in the closed condition, thefirst seat 9 of the frame orcase 3. - The
pivot 14 is associated at a corner of a supportingplate 15 that is approximately U-shaped in plan view and is shaped approximately partially complementarily with respect to thesecond seat 12 and is fixed inside it, for example by welding or adhesive bonding. - Advantageously, the
pivot 14 protrudes from a second supportingelement 35, which is or can be fixed to the supportingplate 15. - An access opening 15a for the end of the
second arm 8 is provided on the supportingplate 15 at thepivot 14 and is shaped advantageously so as to form aneye 8a for rotary interconnection to thepivot 14. - The axis of the
pivot 14 thus constitutes the second hingeing axis for thesecond arm 8 of thebridge 5. - The end of the
second arm 8 is arranged adjacent to asecond wall 15b of the supportingplate 15 that is adjacent to the internallateral surface 4a of theleaf 4, thebase 6 protruding outside it through the access opening 15a formed on the supportingplate 15, and a corresponding slot, not shown in the accompanying figures, which is provided on thelateral surface 13 of theleaf 4. - The
leaf 4 is therefore allowed to rotate of approximately 90° with respect to thesecond arm 8. - The
first arm 7 interacts with first snap-acting means, which are adapted to block removably the rotation of thebridge 5 with respect to the first axis of rotation when a first stable condition rotated through approximately 90°, shown inFigure 5 , is reached starting from the closed condition of theleaf 4, shown inFigure 4 . - Advantageously, such first snap-acting means comprise a
first spring 26, conveniently of the leaf spring type, which is constituted by an elastically deformable metallic lamina that has afirst wing 27 and asecond wing 28, which are approximately flat, are mutually connected by anoblique portion 29, and lie, in the non-deformed condition of thefirst spring 26, on two planes that are approximately mutually parallel and spaced. - The
first wing 27 of thefirst spring 26 is fixed jointly to thefirst wall 16 of thefirst seat 9, while thesecond wing 28 abuts against the lateral surface of thecylindrical tab 24. - Advantageously, a
first slot 30 is provided on the lateral surface of thecylindrical tab 24 and has such a shape that it can accommodate at least partially inside it thesecond wing 28 of thefirst spring 26. - Advantageously, the shape and arrangement of the
cylindrical tab 24 of thefirst slot 30, and of thefirst spring 26 are such that starting from the closed condition of theleaf 4 and upon a rotation of theleaf 4, thesecond wing 28 abuts against the region of the lateral surface of thecylindrical tab 24 that is not affected by thefirst slot 30 and is thus deformed elastically toward thefirst wall 16 of thefirst seat 9. - By turning further the
leaf 4 in the direction for opening it, when the first stable condition rotated through approximately 90°, shown inFigure 5 , is reached, thefirst slot 30 is arranged at thesecond wing 28, which is pushed elastically within thefirst slot 30, blocking, starting from this condition, the further rotation of thecylindrical tab 24, and therefore of thebridge 5, with respect to the first hingeing axis. - A stable condition therefore occurs.
- In the solution shown in
Figures 11 to 15 , the first snap-acting means, adapted to block removably the rotation of thebridge 5 with respect to the first rotation axis, upon reaching, starting from the closed condition of theleaf 4 shown inFigure 9 , a first stable condition rotated through approximately 90° shown inFigure 10 , are instead constituted by ashaft 40, which is jointly connected for rotation to thecylindrical tab 24 and protrudes axially with respect to it; in the part of theshaft 40 that is external to thetab 24, twopins lateral surface 42, which is shaped according to an inclined plane that is preferably helical so as to keep the door always at the same distance from the ground, of abush 43 that is jointly connected to the first supportingelement 25 that is or can be fixed within thefirst seat 9 provided in the frame orcase 3. - Four
seats 44 for temporary and stable interaction with thepins lateral surface 42 along two diametrical planes. - By therefore turning the
leaf 4 in the direction for opening it, thepins seats 44 and move on thelateral surface 42 until they again engagefurther seats 44 after a rotation through 90°, so as to reach a stable position. - The
second arm 8 interacts with second snap-acting means, which are adapted to block removably the rotation of thebridge 5 with respect to the second axis of rotation, starting from the closed condition of theleaf 4, shown inFigure 4 , until such first stable condition rotated through approximately 90°, shown inFigure 5 , is reached. - Advantageously, such second snap-acting means comprise a
second spring 31, conveniently of the helical type, which is inserted in an appropriately providedreceptacle 32 that is formed axially with respect to an appropriately providedsupport 33 that is or can be fixed at least partially within thesecond seat 12 approximately parallel to the internallateral surface 4a, with the free end directed toward the access opening 15a. - A
ball 34 protrudes partially from thesupport 33 by way of the action of the thrust applied by thesecond spring 31 and abuts against the lateral surface of theeye 8a provided at the free end of thesecond arm 8; advantageously, asecond slot 36 is provided on the lateral surface of theeye 8a and has such a shape that it can at least partially accommodate inside it theball 34. - Advantageously, the shape and position of the
eye 8a, of thesecond slot 36, of thesupport 33 and of theball 34 are such that starting from the closed condition of theleaf 4 and up to the first stable condition rotated through approximately 90°, shown for example inFigure 5 , theball 34 is kept pressed by thesecond spring 31 within thesecond slot 36, so as to prevent the rotation of theeye 8a, and therefore of thebridge 5, with respect to thesupport 33 and therefore with respect to thesecond seat 12. - During the rotation from the condition in which the
leaf 4 is closed to the condition in which theleaf 4 is rotated through approximately 90°, thesecond arm 8 is jointly connected for rotation to theleaf 4. - Advantageously, the
concealed hinge 1 comprises means designed to maintain alignment with one or moreadditional hinges 1 associated with a same door orwindow 2; as shown for example inFigures 7 and 8 , such means can be constituted by astraight torsion bar 20, to the lateral surface of which respectively thefirst arms 7 or thesecond arms 8 of thebridges 5 of thevarious hinges 1 associated with a same door orwindow 2 are fixed, for example by welding. - In the exemplary embodiment shown in
Figures 7 and 8 , thetorsion bar 20 coincides with theeye 8a provided at the free end of thesecond arm 8 of thebridge 5 of various mutually connected hinges 1 (only one of which is shown inFigures 7 and 8 ). - The presence of the
torsion bar 20 causes thebridges 5 of thevarious hinges 1 to all rotate synchronously with respect to each other, thus preventing theleaf 4 with which thehinges 1 are associated from being able to tilt abnormally. - Advantageously, the
torsion bar 20 can be fixed to thesecond arms 8 of thebridges 5 of two or moreseparate hinges 1 associated with a same door orwindow 2; in this case, thetorsion bar 20 has a hollow tubular structure, so that it can accommodate, at its free ends, twopivots 14 that protrude from the two second supportingelements 35 that are or can be associated jointly within the frame orcase 3, together with thetorsion bar 20, so as to achieve the hingeing of theleaf 4 to the frame orcase 3. - In this case, the longitudinal axis of the
torsion bar 20 constitutes the second hingeing axis of thebridges 5. - In a further embodiment, not shown in the accompanying figures, the
torsion bar 20 can be fixed to thefirst arms 7 of thebridges 5 of multipleseparate hinges 1 associated with a same door orwindow 2; as an alternative, twoseparate torsion bars 20 can be fixed respectively to thefirst arms 7 and to thesecond arms 8 of multipleseparate hinges 1 associated with a same door orwindow 2. - As an alternative, in a further embodiment, not shown in the accompanying figures, the
torsion bar 20 can be constituted by a solid rod, and it is possible to provide, for example by turning, at the ends of such rod, second pivots with which appropriately provided supports, again not illustrated, are rotatably associable, such supports being jointly associated or associable respectively within the frame orcase 3 and/or within theleaf 4, depending on whether thetorsion bar 20 is associated with the first and/or second arms of thebridges 5 of the connected hinges 1 of thetorsion bar 20. - Advantageously, the
torsion bar 20 can be made of a desired material, such as for example steel, carbon fiber, the material known by the trademark KEVLAR, fiberglass. - In the embodiment shown in
Figures 11 to 15 , the second snap-acting means, which are adapted to block removably the rotation of thebridge 5 with respect to the second rotation axis, starting from the closed condition of theleaf 4, shown inFigure 9 , until such first stable condition rotated through approximately 90°, shown inFigure 10 , is reached, comprise acylinder 45, which protrudes at right angles from the end of thesecond arm 8 in the opposite direction with respect to thepivot 14, adiametrical slot 46 being obtained at the free end of thecylinder 45 and acting as a seat for the rotary interconnection of awheel 47 that is pivoted to the cylinder by means of apivot 48. - The
first spring 26, conveniently of the leaf spring type, interacts with the rolling surface of thewheel 47 and is constituted by an elastically deformable metallic lamina that has thefirst wing 27 and thesecond wing 28, which are approximately flat, are mutually connected by theoblique portion 29 and lie, in the non-deformed condition of thefirst spring 26, on two planes which are approximately parallel and spaced with respect to each other. - The
first wing 27 of thefirst spring 26 is monolithic with aU-shaped support 49, which is jointly connected at its ends to acover 50, which in turn is jointly connected to thefirst wall 16 of thesecond seat 12, while thesecond wing 28 abuts against the rolling surface of thewheel 47. - Conveniently, the
hinge 1 comprises stroke limiting means for the rotation of theleaf 4 with respect to the second axis of rotation, which are constituted advantageously by anabutment element 23 that is preferably approximately L-shaped in plan view and is fixed to the edge of theleaf 4 that is contiguous to the frame orcase 3 in the condition in which theleaf 4 is fully open; theabutment element 23 abuts, in the maximum allowed opening condition of theleaf 4, against thesecond portion 6b of thebase 6 of thebridge 5, so as to stop the rotation of theleaf 4 with respect to the second rotation axis. - Advantageously, the first and second snap-acting means can be replaced with other mechanical means adapted to allow selective positioning among the elements.
- The use of the invention is as follows.
- With reference to the figures, two or
more hinges 1 can be associated with a door orwindow 2, so as to hinge theleaf 4 to the frame orcase 3 of the latter. - As shown for example in
Figures 4 and9 , with theleaf 4 in the closed condition, thefirst arm 7 and thesecond arm 8 of thebridge 5 of thehinges 1 are fully contained respectively in thefirst seat 9 and in thesecond seat 12, and therefore at the most only an extremely small portion of thebase 6 of thebridges 5 is visible from outside. - In the closed condition of the
leaf 4 shown inFigure 4 , theball 34 is pushed by thesecond spring 31 within thesecond slot 36, thus contrasting the rotation of thebridge 5 with respect to the second hingeing axis; in this condition, thebridge 5 is instead free to rotate with respect to the first hingeing axis. - In the closed condition of the
leaf 4 shown inFigure 9 , thefirst spring 26 keeps thecylinder 45 in position, thus contrasting the rotation of thebridge 5 with respect to the second hingeing axis. - By imparting a rotation to the
leaf 4 in the direction for opening it, theleaf 4 rotates with respect to the first rotation axis until it reaches the first stable condition rotated through approximately a further 90°, shown inFigure 5 , and thesecond wing 28 of thefirst spring 26 enters elastically thefirst slot 30, thus blocking the further rotation, in the same direction, of thefirst arm 7 with respect to the first rotation axis. - In the embodiment shown in
Figure 10 , thefirst spring 26 remains still in contact with thecylinder 45. - By continuing to impart a rotation to the
leaf 4 beyond approximately 90°, and always in the same direction, the rotary torque imparted to theleaf 4 exceeds, as shown inFigure 6 , the contrast torque generated by way of the action of the thrust of thesecond spring 31 on the ball 34: such ball thus exits from thesecond slot 36 and glides on the lateral surface of theeye 8a, thus allowing the rotation of theleaf 4 about the second hinge axis with respect to thebridge 5, which in this condition is fixed with respect to the frame orcase 3. - In the embodiment shown in
Figure 11 , the rolling surface of thewheel 47 has passed theoblique portion 29 of thefirst spring 26, thus disengaging the two components and leaving free the rotation of theleaf 4. - In this manner, the
leaf 4 can be turned until it is arranged in a second stable condition that is rotated through approximately a further 90°, in which it is therefore substantially parallel to the plane of arrangement of the frame orcase 3, thus allowing to utilize the entire space of the opening. - In order to close the
leaf 4 it is sufficient to rotate it in the opposite direction to the one described earlier; in a first step, the rotation of theleaf 4 occurs around the second rotation axis, since thefirst arm 7 of thehinge 1 is kept coupled to thefirst seat 9 thanks to the action of thefirst spring 26. - Continuing the rotation of the
leaf 4 in the direction for closing it, at a certain point theball 34 enters thesecond slot 36 and thefirst portion 6a of thebase 6 of thebridge 5 abuts against one of the side walls of thesecond seat 12, preventing the further rotation in this direction of theleaf 4 with respect to the second rotation axis. - By imparting a further rotation to the
leaf 4, when the rotary torque imparted to theleaf 4 exceeds the contrast torque applied to thefirst arm 7 by way of the action of thefirst spring 26, thesecond wing 28 of the latter exits from thefirst slot 30, allowing the rotation of thefirst arm 7, and therefore of theleaf 4, about the first hingeing axis, until the closed condition is reached. - It has thus been found that the invention has achieved the intended aim and objects, a concealed hinge having been provided which allows to achieve the rotation of the leaf of a door or window even through 180° with respect to the closed condition thereof, so as to be able to achieve, even in the open condition, the parallel arrangement of such leaf with respect to the plane of arrangement of the frame or case of the door or window and thus be able to utilize the entire space of the opening with which such door or window is associated.
- Moreover, the production costs of the hinge according to the invention remain low, since it is provided only by means of components that are easy to manufacture and/or assemble.
- The invention is of course susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.
- The materials used, as well as the dimensions that constitute the individual components of the invention, may of course be more pertinent according to specific requirements.
- The various means for performing certain different functions need not certainly coexist only in the illustrated embodiment but can be present per se in many embodiments, including ones that are not illustrated.

- The hinge according to claims 1 and 30, characterized in that four seats are provided, at said lateral surface along two diametrical planes, for temporary and stable interaction with said pins, which as a consequence of a rotation imparted to said leaf in the direction for opening it are forced to disengage said seats and slide on said lateral surface, which is shaped like an inclined plane with a preferably helical arrangement, until they engage again other seats after a 90° rotation so as to reach a further stable position.
- The hinge according to one or more of the preceding claims, characterized in that said second snap-acting means, suitable to block removably the rotation of said bridge with respect to said second rotation axis, starting from the closed condition of said leaf until said first stable condition rotated through approximately 90° is reached, comprise a cylinder that protrudes at right angles from the end of said second arm in the opposite direction with respect to said pivot, a diametrical slot being obtained at the free end of said cylinder and acting as a seat for the rotary interconnection of a wheel that is pivoted to said cylinder by means of a pivot.
- The hinge according to claims 1 and 32, characterized in that a first spring, conveniently of the leaf type, interacts with the rolling surface of said wheel and is constituted by an elastically deformable metallic lamina that has a first wing and a second wing, which are approximately flat and are mutually connected by an oblique portion and are arranged, in the non-deformed condition of said first spring, on two planes which are approximately parallel and spaced with respect to each other, said first wing of said first spring being monolithic with a U-shaped support that is joined at its ends to a cover that in turn is jointly connected to said first wall of said second seat, while said second wing abuts against the rolling surface of said wheel.
