Abstract
The present invention relates to a three-wing hinge for fixtures that comprise a first element and a second element rotating around a rotation axis. The hinge comprises a first component (21) and a second component (22) arranged to be fastened to one element (5, 7) of the elements of the fixture, and a third component (23) in intermediate position between the first (21) and the second component (22), and the first and second components are arranged to rotate relative to the third component around the rotation axis. The hinge is configured so that the first component (21) is pivoted on the third component in an axially adjustable way and the second component (22) is slidingly pivoted on said third component (23) so as to be able to axially slide relative to said third component (23) along the rotation axis. The present invention also relates to a method of making a three-wing hinge.
Description
- The present invention generally relates to a three-wing hinge to be applied to fixtures including a first stationary element and a second element arranged to rotate relative to the first element about a rotation axis.
- More particularly, the present invention relates to a three-wing hinge having, at two opposite ends, two external wings arranged to be fastened to the moving element, for instance a door, and a central wing centrally located between the external wings and arranged to be fastened to the stationary element, for instance an upright of the door.
- Three-wing hinges are generally known and are used in particular for mounting doors, and such a use is referred to hereinafter for the sake of easiness of description.
- Said prior art hinges, which have high robustness properties with respect, for instance, to two-wing hinges, generally include a central pivot configured for allowing rotation of the external wings relative to the central wing about a rotation axis passing through the central pivot.
- A problem common to the three-wing hinges with a central rotation pivot is that said hinges have a structure intrinsically hindering any adjustment in longitudinal direction of the external wings with respect to the central wing.
- Such a problem is clearly a severe limitation to the use of three-wing hinges, which hence cannot be used when an adaptation for instance of the vertical position of a door with respect to the upright is required.
- Attempts at making three-wing hinges allowing an adjustment in longitudinal direction have been made in the past. Reference is made for instance to the hinge disclosed in document
DE 299 21 555 U . - Yet, the solutions tried up to now have been proved unsatisfactory because of the manufacturing costs, of the complexity of assembling the hinge as well as of the low reliability and safety.
- The Applicant has therefore realised that, in view of the need to use three-wing hinges, for instance for reasons of increased robustness, there is the need in the art to make, with reasonable production costs and substantial warranties as to reliability and safety, three-wing hinges allowing the same adjustment operations as provided for by two-wing hinges.
- Thus, it is an object of the present invention to make a three-wing hinge that solves the intrinsic structural problems of such hinges and that has reduced production costs, is simple to be assembled and is highly reliable.
- The object is achieved by means of the three-wing hinge as claimed.
- The present invention also concerns a method for making a three-wing hinge.
- According to the invention, the three-wing hinge is configured so that:
- a first component or wing of the hinge is pivoted on a third component or wing in an axially adjustable way; and
- a second component is slidingly pivoted on the third component or wing so as to be capable of axially sliding relative to the third component along the rotation axis.
- In particular, thanks to the fact that the third component or wing has an upper cavity arranged to house a pivot for the rotatable connection with the first component or wing, and a lower cavity arranged to house a pivot for the rotatable connection with the second component or wing, which cavities are separated by a solid portion of material, the construction of the hinge according to the invention is cheap, requires a very small number of pieces, thereby allowing a very simple assembling, and ensures reliability and safety.
- In a preferred embodiment, said third component or wing is worked by turning in order to form said upper cavity and said lower cavity.
- The above and other features and advantages of the present invention will become apparent from the following description of preferred embodiments thereof, made by way of non limiting example with reference to the accompanying drawings, in which elements denoted by a same or similar numerical reference correspond to elements having the same or similar function and construction, and in which:
-
Fig. 1 is an overall view of an application of hinges according to the present invention; -
Fig. 2 is a cross-sectional view of the hinge according to the invention; and -
Fig. 3 shows a pivot for adjusting the hinge according to the invention. - Referring to
Fig. 1 , a three-wing hinge 10 according to the present invention can be applied to a fixture including a first element 7, for instance a door, and a second element, for instance an upright 5 of a frame 6. -
Hinge 10 includes first and second components (upper and lower wings) 21 and 22, respectively, arranged to be fastened for instance to the first element (door) 7, and a third component (central wing), arranged to be fastened for instance to the second element (upright) 5 of frame 6. - According to the invention,
hinge 10 also includes afirst pivot 31 configured for being introduced betweenupper wing 21 andcentral wing 23, and asecond pivot 32, coaxial to the first one and configured for being introduced betweencentral wing 23 andlower wing 22. - The first and
second pivots wings central wing 23, fastened to upright 5, about a rotation axis corresponding to the axis of the pivots. - Hinge 10 preferably also includes first and
second spacers upper wing 21 andcentral wing 23 and betweenlower wing 22 andcentral wing 23, respectively. The spacers are arranged to make the mutual rotation of the wings easier, as a skilled in the art can readily understand, to become deformed if subjected to pressure and to prevent, at the same time, penetration of dust and/or humidity intohinge 10. - In the preferred embodiment,
wings - In order to receive the
first pivot 31,upper wing 21 includes abody 24, e.g. cylindrical, having acavity 25 with cylindrical shape protected at one end, for instance, by acap 19a, preferably of rubber or plastics, in order to prevent penetration of dust and/or humidity intohinge 10. -
Cavity 25 has a substantially smooth or non-threaded internal surface in afirst zone 25a, close tocentral wing 23, and has a threadedsurface 26 in asecond zone 25b, opposite or distal with respect to thefirst zone 25a. -
Upper wing 21 also includes, in correspondence for instance of thefirst zone 25a, ahole 26a, for instance a threaded hole, preferably orthogonal to the cavity and arranged to house a locking or safety element orsafety dowel 27a, configured for locking thefirst pivot 31 in a determined position, as it will be disclosed in detail below. - In order to receive the
second pivot 21,lower wing 22 includes abody 44, e.g. cylindrical, having acavity 45 with cylindrical shape configured so as to have a substantially smooth internal surface over its whole length and protected at one end, for instance, by acap 19b, preferably of rubber or plastics, in order to prevent penetration of dust and/or humidity intohinge 10. -
Cavity 45 is arranged to receive thesecond pivot 32 and to allow, jointly with the pivot, both the rotation oflower wing 22 relative tocentral wing 23 and the axial sliding of thesecond pivot 32 incavity 45 of the lower wing, as it will be disclosed in detail below. - Always in accordance with the invention,
central wing 23 includes a body, e.g. cylindrical, having formed therein a first cavity (upper cavity) 55, configured for housing afirst end 35a of thefirst pivot 31, and asecond cavity 56, opposite the first one and configured for housing afirst end 65a of thesecond pivot 32, said first and second cavities being defined and separated from each other by a solid intermediate central partition. - Said first and
second cavities - Preferably, said
first cavity 55, and possibly also thesecond cavity 56, has a bottom that preferably is rounded and a smooth internal surface. - In the preferred embodiment, a
hole 56a, for instance a threaded hole, preferably orthogonal to thesecond cavity 56, is provided in correspondence of thesecond cavity 56. Said hole is configured for housing a retaining member or retainingdowel 57a, configured for blocking the relative sliding of thesecond pivot 32 relative tocentral wing 23, as it will be disclosed in detail below. - The
first pivot 31 has afirst end 35a with a smooth surface and preferably ends with aball 37a arranged to make relative rotation ofupper wing 21 relative tocentral wing 23 easier. At asecond end 35b, thefirst pivot 31 has athread 36 arranged to cooperate with threadedsurface 26 ofcavity 25 so as to enable the axial sliding of thefirst pivot 31 relative toupper wing 21, as a result of the screwing/unscrewing ofpivot 31. - In particular, the first pivot has, at
second end 35b, aseat 38, for instance a hexagonal seat for an Allen key (setscrew spanner), arranged to allow screwing/unscrewing pivot 31 and hence adjusting its position relative toupper wing 21. - The
second pivot 32, preferably with a smooth surface, has, atfirst end 65a housed, in use, in thesecond cavity 56 ofcentral wing 23, a circumferential cut 67a, for instance V-shaped, which is configured for being engaged in use by retainingdowel 57a, thereby preventing the axial sliding of thesecond pivot 32 relative tocentral wing 23. - The operation of three-
wing hinge 10 described above is as follows. - In order to describe the operation, it is assumed, for instance, that upper and
lower wings hinge 10 are fastened to door 7 and that the central wing is fastened to upright 5 of frame 6. - In such a condition of use, when an adjustment of the position of door 7 relative to upright 5 becomes necessary,
seat 38 of thefirst pivot 31 is operated on, for instance by means of an Allen key so as to turn it in clockwise or counterclockwise direction depending on the kind of axial adjustment to be applied to the door. - As a skilled in the art can readily understand, the screwing/unscrewing operation correspondingly entails the displacement of
upper wing 21 relative tocentral wing 23, since thefirst pivot 31 abuts, by means ofball 37a, against the bottom of thefirst cavity 55 ofcentral wing 23 and compelsupper wing 21 to axially displace. - Yet,
lower wing 22 is associated withupper wing 21, since it is fastened, for instance, to door 7, and thus it consequently moves relative tocentral wing 23. - Advantageously, the
second pivot 32 does not axially slide relative tocentral wing 23 and thus it axially slides along the axis oflower wing 22. - Once the adjustment has been completed, in order to prevent the adjustment from changing because of the rotation of door 7 relative to upright 5, it is advantageously envisaged, for instance, that
safety dowel 37a is tightened against thefirst pivot 31, thereby preventing the latter from screwing or unscrewing relative to threadedsurface 26 ofcavity 25. -
Hinge 10 as described and shown has a drop shape but, as a skilled in the art can readily understand, it may have any shape compatible with the described structure and functions. Similarly, the positions of the lower and upper wings may be mutually exchanged, without thereby departing from the scope of what has been disclosed and claimed. - Of course, obvious changes and modifications can be made to the above description in respect of size, shape, materials and components, as well as in respect of the details of the illustrated construction and the operating manner, without departing from the scope of the invention as claimed in the following claims.
