• the upper and lower elements are suitable for being connected to each other by means of a fulcrum pin, around which the leaf can be rotated.
• the pin presents a single length of constant diameter, but there are others in which this pin extends longitudinally over two coaxial or mutually eccentric lengths, with diameters different from each other.
• the pin presents a first cylindrical length surmounted by a second eccentric length of smaller diameter and capable of being enveloped by a bush which incorporates an axial bearing and is provided with an external grooved sleeve, capable of engaging a conjugate housing formed in the upper element of the hinge. The relative angular position of the bush and the upper element will determine the contact pressure between the rotatable leaf and the frame, and the centring of the leaf on the opening delimited by the frame.

Therefore, a hinge of this type is such as to represent a new and original source of economic advantage, capable of altering the current market of adjustable hinge for doors and windows.

• FIG. 6 is a view in transverse section of a third preferred embodiment of figure 2.
• no. 1 indicates an adjustable hinge for connecting a leaf 2 of a door or window to a stile 3 of a respective frame 4 rotatably around a fulcrum axis 5 which is substantially vertical in figure 1.
• hinge 1 includes a first member 10 and a second member 20 respectively connected rigidly to leaf 2 and stile 3 so as to have the former supported by the latter.
• first and second members 10 and 20 are connected to each other in axially fixed manner, by gravity which acts by thrusting the former onto the latter, and freely rotatably by virtue of a fulcrum member 30, usually, and in this case also, realized by a cylindrical pin which, for simplicity, is identified by the same reference number 30.
• the second member 20 and the fulcrum member 30 are separated axially by an axial plain bearing 50 carried at its lower end in figure 2 by a bush 52, whose function is to reduce the friction between boundary surfaces of the two members 20 and 30 in mutual contact.
• bush 52 houses pin 30 internally to a cylindrical axial hole 54 located eccentrically with respect to a corresponding external cylindrical sleeve 56.
• the eccentricity of hole 54 has the purpose of allowing the adjustment of the position of pin 30, and therefore of leaf 2, parallel and transversely to stile 3.
• pin 30 presents a free end 31 which engages bush 52 in figure 2, and an intermediate portion 32 provided with a housing 34 transverse to axis 5 and threaded, for housing a bolt 41 of determinate length L as seen in figure 2 , in which it has been represented for convenience by a head 42 with recessed hexagon, without this representing a limitation to the extension of the applicability of the idea of hinge which is being illustrated.
• pin 30 is supported by member 10 inside an axial housing 11 capable of accommodating portion 32 of pin 30, and having a squared section substantially rectangular as can be seen in figure 3, capable of constituting a transverse guide for pin 30 as will be better seen below.
• housing 11 approximates by excess the diameter of pin 30 by a fitting tolerance.
• housing 11 is occupied for its entire respective width by bolt 41, and for this reason it has a width substantially identical to the length L of bolt 41 itself, increased by a tolerance necessary for carrying out the insertion of portion 32 of pin 30 once bolt 41 has been inserted into housing 34 of pin 30 itself, transversely to housing 11 itself.
• member 10 presents, from the direction of a respective flange 70 for attaching it to leaf 2, a pair of threaded holes 14 whose axes 15 are located transversely to axis 5 and lie parallel to each other on a plane which contains axis 5 itself.
• Holes 14, furthermore, have diameters which are substantially identical to each other and which approximate by defect to a transverse diameter of head 42 of bolt 41 so as to retain it axially inside housing 11.
• these holes 14 are located symmetrically with respect to an intermediate portion of respective member 10, and therefore are respectively equidistant from upper and lower sides 13 of member 10 itself.
• the corresponding hole 14 may be occupied by a grub screw 16 capable of locking bolt 41 in rotation, and therefore of preventing accidental alteration of the position of pin 30 inside axial housing 11. Accordingly, the assembly of bolt 41, housing 34 which it occupies and the respective hole 14 constitutes an adjustment device 40 for the transverse position of axis 35 within axial housing 11.
• hinge 1 has to be used to support a leaf 2 in such a way that the latter is openable in a clockwise direction, then pin 30 must be mounted inside member 10 as in figure 2, with end 31 facing downwards, so as to occupy hole 54 in bush 52. Consequently, the hole 14 to be used for adjusting the position of axis 35, and therefore the eccentricity of the position of pin 30 inside housing 11, will have to be the hole 14 located nearest to member 20, and therefore the lower one in figure 2.
• hinge 1 must be used to connect a leaf 2 which is openable in an anticlockwise direction, to the respective stile 3, the only precaution necessary will be to set up hinge 1 with member 20, and thus also member 10, rotated through 180° with respect to the position taken in figure 2, leaving pin 30 oriented as in figure 2, but using the other hole 14, which will always be the hole 14 which ends up located lowest .
• pin 30 presents, furthermore, at least one flat 36, parallel both to axis 35 and to housing 34.
• This flat 36 which forms a locating surface for pin 30, accessible transversely to axis 5, is located at a determinate distance from housing 34, defined in such a way as to be substantially intermediate between holes 14 of member 10 when pin 30 occupies axial housing 11, as is seen in figure 2.
• Member 10 therefore presents, in a position substantially intermediate between axes 15 of the two holes 14, but also between the upper and lower surfaces 13 of member 10 itself in figure 2, a hole 18 which has been illustrated with a dotted line in figure 3, and it has an axis 19 transverse to axis 15 of holes 14 and to axis 35 of pin 30, and is substantially equidistant from sides 13 of member 10.
• An indication of axis 19 is also given in figure 2, to allow better identification of hole 18 on the basis of the description given above.
• hole 18 can be occupied by a threaded grub screw 60, which is usable for rigidly connecting together pin 30 and member 10, once the stage of adjusting the transverse position of axis 35 in housing 11 is completed, as will be better explained further on.
• holes 14 are arranged symmetrically with respect to the longitudinal axis of hole 18, in such a way that first member 10 is usable for supporting right-hand and/or left-hand leaves 2.
• the assembly including hole 18, grub screw 60 itself and flat 36 constitutes an anchoring device 61 for pin 30, which allows pin 30 to be rigidly connected longitudinally with axis 35 in a determinate transverse position, and allows a rigid connection to be guaranteed between member 10 and pin 30, independently of the preselected position of axis 35 itself.
• pin 30 presents a constant diameter substantially identical to a principal dimension of the squared housing which accommodates it in the respective member 10; pin 30 includes a through housing 34 threaded to accommodate screw 41; pin 30 including a striking element/flat 36 parallel both to axis 35 of pin 30 and to housing 34 in order to be engaged by a grub screw 60; member 10 has two transverse holes 14 in a respective wall which is lateral for the respective housing 11 for accommodating pin 30; through holes 14 are threaded to accommodate stably and selectively a grub screw 16 for locking the rotation of bolt 41; grub screw 60 engages the respective hole 18 to rigidly connect member 10 and pin 30; the distance between housing 34 and flat 36 approximates to half the spacing between holes 14, and the extension of flat 36 transversely to axis 35 allows pin 30 to be locked axially within housing 11 itself by means of grub screw 60 in any position
• hinge 1 is usable selectively for the installation of right-hand or left-hand leaves 2, keeping pin 30 oriented as in figure 2 and simply rotating members 10 and 20 through 180°.
• hinge 1 is can be freely prepared before installation on the basis of the location of the fulcrum axis of the leaf which is to be connected to the stile
• the procedure for assembling a hinge 1, and in particular that shown in figure 2 is as follows: first, choose the orientation of flange 70 on the basis of the need to use hinge 1 for the installation of a right-hand or left-hand leaf 2; next, couple together pin 30 and bolt 41, which is introduced into its respective housing 34 by screwing it in; subsequently, insert pin 30 complete with bolt 41 from the bottom, with head 42 of bolt 41 located on the same side as holes 14; once head 42 is lined up with the hole 14 which is located towards the bottom, proceed with the adjustment of the transverse position of axis 35, and insert grub screw 16 into the same hole 14 in order to lock bolt 41 axially, and also grub screw 60 into hole 18 to bring about axial locking of pin 30.
• hinge 1 set forth above presents the possibility of adjusting the position of pin 30 on two horizontal axes.
• member 20 configuring the respective end portions of the axial housing 21 with threads 23 for supports 25 consisting of externally threaded cylindrical bodies, having internally a recess for an operating key or a screwdriver. Forming a thread 23 for both end portions of housing 21 will allow member 20 to be configured selectively for left-hand or right-hand leaves, as required.
• hinge 1 it is possible very simply to make hinge 1 more secure, and therefore particularly indicated for installation in areas at high risk of break-ins.
• forming hole 18 on the side of the base of flange 70 itself, and therefore on the side on which contact is produced between flange 70 and leaf 2 makes grub screw 60 accessible only on condition that leaf 2 is open.
