Description
- The present invention concerns a hinging device of the so-called concealed type, configured to hinge closing elements, in particular armored doors, with respect to a fixed element, such as a support frame or structure.
- By "concealed hinging device" we mean a device which is not visible when it is associated with the closing element to be hinged.
- According to a particular use of the hinging devices according to the present invention, each closing element is hinged on two of said hinging devices, which are configured to be disposed preferably aligned along the same vertical hinging axis and positioned one on an upper zone of the closing element and the other on a lower zone of the closing element, to cooperate respectively with an upper part of the fixed element, and the other with a lower part of the fixed element, or directly with the floor.
- Concealed hinging devices or hinges are known, for hinging closing elements, such as armored doors, with respect to corresponding fixed elements. These fixed elements comprise, for example, a very robust frame, for example metal, which defines an aperture, or gap, with a normally rectangular section. Such hinging devices comprise at least two pins, or pintles, located along the same axis of rotation or hinging, which is usually vertical.
- An armored door, for example, has a weight that is usually much greater than traditional doors, that is, it has a weight that is much higher than 80 kg.
- In particular, many concealed hinges are known, each comprising two hinging elements and a central pin on which the latter are hinged. In these types of hinges one of the hinging elements is configured to be attached on a pillar, or a jamb, of the support frame, while another of the two hinging elements of each hinge is configured to be attached on the closing element to be hinged, usually in correspondence with a lateral edge of the latter.
- These known concealed hinges have the disadvantage that they are usually rather complex and expensive and often not suitable to support very heavy closing elements, such as armored doors, or other.
- In the field of armored doors, in order to hinge them to a support frame, it is also known to install two hinging devices disposed one on an upper horizontal part of the support frame and the other on a lower part of the support frame, or directly on the floor, and each comprising a hinge pin disposed coaxial to the axis of rotation.
- Alternatively, each hinging device can be installed in a compartment made in the armored door to be hinged, at a determinate distance from a lateral edge of the latter, opposite the edge where the lock is situated. In this known solution a hinging device has the hinge pin facing upward, to cooperate with a corresponding hinging hole made on the upper horizontal part of the support frame, and another hinging device has the hinge pin facing downward, to cooperate with a corresponding hinging hole made on the lower part of the support frame, or directly on the floor.
- In the field of concealed hinging devices or hinges, in particular for hinging closing elements such as armored doors, one of the technical problems to be faced and resolved, known to all those of skill in the art, is the correct positioning of the closing element with respect to the fixed structure, especially during assembly, but also during use.
EP2208843 A2 discloses an example of such a concealed hinging device. - Therefore, one purpose of the present invention is to provide a concealed hinging device for hinging closing elements, such as armored doors, which is robust, simple to make and reliable and which, at the same time, allows an easy and convenient installation of the closing element to be hinged.
- Another purpose of the present invention is to provide a concealed hinging device for hinging closing elements, such as armored doors, which allows an easy adjustment of the position of its hinge pin with respect to the corresponding hinging hole, in at least two directions.
- The Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
- The present invention is set forth and characterized in the independent claim, while the dependent claims describe other characteristics of the invention or variants to the main inventive idea.
- In accordance with the above purposes, a concealed hinging device, according to the present invention, to hinge a closing element, in particular an armored door, with respect to a fixed element, comprises a hinging element configured to be disposed coaxially to a hinging axis and mounted on a support mean configured to be disposed in a compartment made in the closing element thereof.
- According to the present invention, the hinging device also comprises both first adjustment means configured to selectively adjust the position of the hinging element in a sliding direction, substantially perpendicular to the hinging axis, and second adjustment means configured to selectively adjust the axial position of the hinging element along the hinging axis.
- Said support mean comprises a containing box mounted slidingly on a support element configured to be disposed perpendicular to the hinging axis, so that the containing box can be selectively moved in said sliding direction.
- The containing box is disposed with ample play in a housing of the support element, and sliding means are provided to allow the containing box to freely slide in said sliding direction together with the hinging element.
- The support element comprises a fin provided with two eyelets disposed on opposite sides with respect to said housing and aligned in said sliding direction; moreover the sliding means comprise two guide pegs inserted in the two eyelets and fixed to a support plate, which in turn is removably attached to the containing box.
- In accordance with an embodiment of the present invention, the sliding means also comprise two corresponding stop elements attached to the two guide pegs, but on the opposite side of the fin and detached from the latter.
- In accordance with an embodiment of the present invention, the first adjustment means comprise a threaded bar substantially parallel to the sliding direction and having a first end connected to the support mean, an intermediate zone screwed onto a support plate mounted in a fixed position, and a second end configured to be driven from the outside of the closing element.
- In accordance with an embodiment of the present invention, the hinging element can be screwed onto the support mean, in order to slide axially with respect to it, while remaining coaxial with the hinging axis.
- In accordance with an embodiment of the present invention, the second adjustment means comprise a cylindrical bar substantially parallel to said sliding direction and having a first end provided with a worm screw engaging with a toothed wheel coaxial with the hinging element and a second end configured to be driven from the outside of the closing element, so that a rotation of the cylindrical bar causes a corresponding rotation of the hinging element with respect to the support mean and a consequent axial displacement, along the hinging axis, of the hinging element with respect to the support mean.
- In accordance with an embodiment of the present invention the hinging element is configured to face both upward and downward, moreover the first and second adjustment means are configured to be positioned, selectively and alternatively, on one side or on the opposite side of the support mean, in said sliding direction, so that the first and the second adjustment means can be driven from the outside of the closing element both when the hinging element is facing upward, and also when the hinging element is facing downward.
- These and other characteristics of the present invention will become apparent from the following description of some embodiments, given as a non-restrictive example with reference to the attached drawings wherein:

According to some solutions, thesupport frame 11 comprises twovertical uprights upper element 19 and alower element 20, also horizontal, which according to a variant, not shown in the drawings, may coincide with the floor, or be incorporated into the floor. - According to a second embodiment, shown in
fig. 2 , theclosing element 10 is mounted specular on thesupport frame 11, so that thelock 14 is adjacent to the leftlateral edge 16 to cooperate with the vertical upright 17 of thesupport frame 11. The hinging axis X is positioned at the determinate distance D from the rightlateral edge 15 and the twohinging devices hinging device 13 on the upper zone of theclosing element 10 and thehinging device 12 on the lower zone of theclosing element 10. - The hinging device 12 (
fig. 3 ) comprises a hinging element, in this case a pin, orpintle 21 substantially cylindrical, mounted axially sliding in a support mean, in this case a containing box 22 (figs. 4 and 5 ) and configured to be disposed coaxially with the hinging axis X. - In particular, the
pin 21 has alower part 21a (fig. 5 ) threaded and screwed into a corresponding female thread (not shown in the drawings) present in the containingbox 22, so that, by rotating thepin 21 with respect to the latter, as will be described in detail below, thepin 21 can move axially with respect to the containingbox 22. - The containing
box 22, together with thepin 21, is mounted sliding in a sliding direction Y, which is horizontal in use, on afin 23 of a support element, in this case ametal sheet 24, L-shaped and configured to be attached horizontally in an upper compartment 25 (fig. 1 ) made in the upper zone of theclosing element 10. Thesheet 24 is disposed perpendicular to the hinging axis X. - In particular, the containing box 22 (
fig. 4 ) is disposed with ample play in ahousing 26, in this case rectangular, made in thesame fin 23 of thesheet 24, and is attached, by means of twoscrews 27, to anupper plate 28, which is provided with athrough hole 29 in which thepin 21 passes with slight play. - Two
stop elements 30 and 31 (fig. 3 ), shaped like a disk, are disposed in the lower part of thefin 23 of thesheet 24 and are associated with twocorresponding guide pegs pin 21 and inserted in twocorresponding guide eyelets fin 23 of thesheet 24, on opposite sides with respect to thehousing 26 and aligned in the sliding direction Y. - The guide pegs 32 and 33 are attached to the
upper plate 28 so that the latter is selectively sliding on thefin 23. The attachment of the guide pegs 32 and 33 to theupper plate 28 is such that it does not generate friction, or gripping, of thestop elements fin 23 and theupper plate 28. - The
upper plate 28, thestop elements guide pegs box 22 to slide freely in the sliding direction Y. - One
end 37 of a threadedbar 38 is attached, by means of a collar 36 (fig. 5 ), to the containingbox 22, and has its axis parallel to the sliding direction Y. The threadedbar 38 is screwed into a threadedhole 39 made in asupport plate 40. Thesupport plate 40 is attached in the lower part of thefin 23 of thesheet 24, perpendicular to it. - The threaded
bar 38 has another end 41 (figs. 3 and6 ) disposed in proximity to the left lateral edge 16 (figs. 1 and3 ) of theclosing element 10 and is configured to be driven by a tool, for example a screwdriver, or an Allen key, through a first aperture 42 (fig. 3 ), made in the same leftlateral edge 16 of theclosing element 10. - The threaded
bar 38 defines first adjustment means configured to adjust the position of thepin 21 in the sliding direction Y. - A
cylindrical bar 43 is mounted, axially rotatable, parallel to the threadedbar 38 and is supported by thesame support plate 40. - At one of its ends 44 (
fig. 7 ), thecylindrical bar 43 is provided with aworm screw 45 permanently engaged with a corresponding toothed wheel 46 (figs. 5 and7 ) rotatable around the hinging axis X and coupled with thepin 21 in order to make it rotate with it, but leaving it free to move axially with respect to it. Theworm screw 45 and thetoothed wheel 46 are disposed inside the containingbox 22. - The
cylindrical bar 43 has its other end 47 (fig. 3 ) disposed in proximity to the left lateral edge 16 (figs. 1 and3 ) of theclosing element 10 and is configured to be driven by a tool, for example a screwdriver, or an Allen key, through a second aperture 48 (fig. 3 ) made in the same leftlateral edge 16 of theclosing element 10. - The
cylindrical bar 43, theworm screw 45 and thetoothed wheel 46 together define second adjustment means configured to selectively adjust the axial position of thepin 21 along the hinging axis X. - The hinging
device 12, in the example provided here, is positioned in the upper compartment 25 (fig. 1 ) of theclosing element 10 so that thepin 21 is facing upward, to cooperate with a corresponding hinging hole, not shown in the drawings, made on theupper element 19 of thesupport frame 11, coaxially with the hinging axis X. - The hinging
device 12 described above allows a simple double adjustment of the position of thepin 21, that is to say, both a first adjustment in the sliding direction Y, together with the containingbox 22, with respect to thesheet 24 and therefore to theclosing element 10, and also a second adjustment along the hinging axis X, with respect to the containingbox 22 and therefore to theclosing element 10. - In fact, by screwing or unscrewing the threaded
bar 38 on thesupport plate 40, the first adjustment of thepin 21 in the sliding direction Y is made, moving it more to the right, or more to the left (figs. 1 and3 ), with respect to a central nominal position with respect to thehousing 26. - On the contrary, by rotating the cylindrical bar 43 (
fig. 6 ), in a clockwise or anti-clockwise direction, the second adjustment of thepin 21 is made, thanks to the coupling of the worm screw 45 (fig. 7 ) and thetoothed wheel 46. In fact, the rotation of the latter also causes the rotation of thepin 21, which, thanks to the threaded coupling of itslower part 21a (fig. 5 ) and the containingbox 22, ascends or descends with respect to the latter and therefore enters more or less into the corresponding hinging hole made on the upper element 19 (fig. 1 ) of thesupport frame 11. - The above two adjustments can be made both during the assembly of the
closing element 10 on thesupport frame 11, and also during the use of theclosing element 10 itself, intervening from the outside of the latter on the threadedbar 38 and/or on thecylindrical bar 43. - The hinging
device 13, shown in detail infig. 8 , is similar to thehinging device 12 described heretofore, with the difference that the position of the threadedbar 38, thesupport plate 40 and thecylindrical bar 43 is specular with respect to thepin 21 and to the containingbox 22. - In particular, in the example provided here, the hinging
device 13 is positioned in a lower compartment 49 (fig. 1 ) of theclosing element 10, so that thepin 21 is facing downward, in order to cooperate with a corresponding hinging hole, not shown in the drawings, made on thelower element 20 of thesupport frame 11, coaxially with the hinging axis X. - The hinging
device 13 also allows an easy dual adjustment of the position of itspin 21, similarly to what was described above for thehinging device 12. - In the embodiment shown in
fig. 2 , the hingingdevice 13 is disposed in theupper compartment 25, with thepin 21 facing upward, while thehinging device 12 is disposed in thelower compartment 49, with thepin 21 facing downward. - It is understood that modifications and/or additions of parts may be made to the
hinging devices - It is also clear that, although the present invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of hinging devices, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
