Adjustable hinge for door frames

Description

[0001] The present invention relates to a hinge which is adjustable on three axes, for doorframes, in particular for heavy metal doorframes, that is to say, of the type which are large and, therefore, weigh more than standard interior models.

[0002] The hinges used for the above-mentioned doorframes (that is to say, for exterior doors, gates, etc.), must satisfy special safety criteria and, therefore, differ from those used for normal (interior) doorframes. These differences are of a structural nature and consist of larger dimensions, partly necessary due to the greater weight of the doorframes, and the fact that they are fixed in place using screws which must be concealed by covering them with special anti-tampering covers. Moreover, due to the particular nature of the application, these hinges require adjustment to allow optimum adjustment of the position of the mobile frame relative to that of the fixed frame, given the reduced tolerance between them.

[0003] Such hinges consist of two bodies, normally made of aluminium, which can be fixed to the mobile and fixed frames, and a steel hinge pin, which can be inserted in respective through-holes in the bodies inside a centring bushing (normally made of plastic and self-lubricating). The centre of the pin is fitted with a collar which is integral with the pin and whose diameter is greater than that of the through-holes in the bodies, to prevent the pin from exiting the seats in the bodies (see also patent IT - 1.221.237 by the Applicant).

[0004] The bodies have brackets for fixing to the doorframe, through which there pass, in a direction perpendicular to the hinge pin, strong screws whose heads are housed in respective seats in the brackets.

[0005] The latter, outside the screw heads, have guides defining seats for strong covers which slide parallel with the hinge pin. The covers conceal the screw heads completely and define a surface which makes contact with the entire cylindrical part of the hinge, in which there is the hole for the bushing, and the free end of the bracket which starts from this cylindrical part and bears the cover guides.

[0006] The above-mentioned bushings normally consist of a cylindrical element, closed at one end, and a collar located at the open end. They also have an axial hole, offset relative to the longitudinal axis of the cylindrical element, and a set of projections or teeth, normally located on the outside of the bushing and immediately below the collar for contact with the hinge body, equidistant and designed to engage with matching seats made in the holes in the hinge bodies.

[0007] The shape of the bushings allows the axis of the hinge pins to be moved on a plane parallel with the doorframe, by rotation of the pins about their axes, thus adjusting the position of the mobile frame relative to the fixed frame. This adjustment is carried out by raising the wing with the relative removal of the teeth from the seats of one or both bushings on the hinge, adjusting them in the new position, and finally re-inserting the bushings in the hinge bodies, simultaneously lowering the wing into the new position.

[0008] However, this operation is awkward not only due to the difficulties involved in its performance, but also because the wings to be raised are, as indicated, very heavy and the first axial adjustment is not always the definitive one, meaning that the adjustment process is time consuming for the fitter or fitters.

[0009] For this reason, the Applicant has designed a solution (see patent EP - 794.307) in which each bushing on the hinge consists of two separate elements, connected to one another by axial connecting means and free to rotate relative to one another. The first element is cylindrical and houses the portion of the pin, since it has a seat for holding the pin which is offset relative to a longitudinal axis of the bushing, whilst the other element defines a first collar whose diameter is greater than the diameter of the axial hole which houses the bushing. Adjustment means act upon the first element, being designed to vary its position relative to the second element by rotating the first element, with an action from outside the assembled and operating hinge body, between several stable conditions which are defined by grooves in the axial hole.

[0010] This solution makes it easier to adjust the position between the mobile frame (which no longer has to be raised for each adjustment) and the fixed frame.

[0011] However, both of the above-mentioned solutions allow adjustment of the position of the mobile frame in small steps, that is to say, according to the number of grooves on the circumference of the bushings and, respectively, in the seats of the hinge bodies, whilst the market for such products requires more precise adjustment of the doorframes, through a more continuous pin - bushing movement system able to obtain positioning which is more correct than the previous solutions.

[0012] In addition, the hinge would preferably, for the purpose of structural completeness, allow adjustment of the height of the mobile frame relative to the fixed frame. This adjustment can be obtained through a solution known for some time now, using ring-shaped spacers, that is to say, washers, which may be inserted on the pin and have the same diameter as the pin collar, thus separating the two hinge bodies.

[0013] This solution, although rapid, is disadvantageous and difficult to implement, since the wings to be raised are, as indicated, very heavy and the desired measurement is not always obtained with a single spacer insertion operation, meaning that the process is time consuming for the fitter or fitters. The rings are normally of given thicknesses, therefore, the adjustment of the height of the two hinge bodies is limited, according to the number of spacers inserted and is not continuous, as is often required during assembly of such doorframes.

[0014] It is also known from document EP0467075 a hinge plate for doors and the like which comprises a hinge part presenting an elongate recess, through which a hinge pin extends. The hinge pin is surrounded by a guide part of larger diameter which has, on one side, a toothing engaging in a toothing in one flank of the recess. In the event of a displacement of the hinge pin along the recess, the guide part rolls down. The hinge pin can be moved and fixed in the assumed position by means of a transversely extending screw which engages into the hinge pin and passes from outside through the wall of the recess and the guide part and which engages into a threaded bore of the hinge pin.

[0015] The aim of the present invention is, therefore, to overcome the above-mentioned disadvantages by providing a hinge for doorframes which has a simple structure, is extremely precise and rapid in adjusting the doorframe through three movements, that is to say, on the three axes of the hinge.

[0016] Another aim of the present invention is to provide a hinge which is extremely practical and safe when assembled on the mobile and fixed doorframes.

[0017] The technical features of the present invention, in accordance with the above aims, are apparent in the claims herein, and the advantages are more clearly described in the detailed description below, with reference to the accompanying drawings, which illustrate an embodiment of the invention, without limiting the scope of its application, and in which:

[0018] With reference to the accompanying drawings, and in particular Figures 1 and 2, the hinge disclosed may be used on "heavy" doorframes, such as exterior doors, main front doors, gates, etc.

[0019] This hinge, indicated as a whole by the numeral 1, comprises a first and a second body 2 and 3, which may be attached to a mobile frame IM and to a fixed frame IF (schematically illustrated in Figure 5, being of the known type and not part of the subject matter of the present invention) by means of brackets 4 and 5 which house screw means 100 for fixing to the doorframes (described in more detail below).

[0020] The two bodies 2 and 3 are joined together by a pin 6 inserted, inside a first and a second lower and upper cylindrical bushing 7 and 8, in axial through-holes 9 and 10 in the first and second bodies 2 and 3, the holes extending along a longitudinal axis Z (which defines the vertical axis of the hinge).

[0021] Between the first bushing, which is the "upper" bushing 7, and the relative hole 9, there are first means 11 for adjusting the position of the hinge pin 6, acting between the bushing and the hole 9, in such a way as to allow the position of the pin 6 relative to the longitudinal axis Z to move radially in both directions and on a plane P parallel with the doorframe.

[0022] As illustrated in Figures 3, 4 and 5, these first means 11 for adjusting the pin 6 envisage, at least as regards the hinge body 2 defined by the upper part of the hinge 1 when assembly is complete, means 35 for rendering the bushing 7 and the portion of the pin 6 housed in it integral, so that they define a single adjustable body.

[0023] In addition, the bushing 7 has an outer radial projection 12 which can engage in a notch 13 in the inner surface of the hole 9 in the hinge body 2. The engagement of the projection 12 in the notch 13 defines a pivoting point F (see Figure 3), in the style of a cam, for the first bushing 7, allowing it to perform a pendular movement in both directions together with the portion of the pin 6 housed in it, thanks to relative means 14, which can be operated from the outside, acting between the pin 6 and the hole 9 in such a way as to allow the above-mentioned adjustment of the position of the pin 6.

[0024] Obviously, the second bushing 8 may also have adjustment means designed to allow the variation of the part of the pin 6 housed in it, in particular relative to an axis perpendicular to the plane P.

[0025] Such means are of the known type (for example, the second bushing 8 is made with an eccentric hole) and are not, therefore, described here.

[0026] More specifically, the above-mentioned connecting means 35 consist of one or a pair of opposite (in the case of a pair) flat surface sections 36 on the portion of the pin 6. These flat sections 36 connect, in such a way that they can slide, inside the bushing 7 which, in turn, has one or a pair of flat surfaces 37, allowing relative locking between the pin 6 and bushing 7. In other words, a single body is formed, which is adjustable and consists of the portion of the pin 6 and the bushing 7, upon which the pendular movement means 14 can act.

[0027] During assembly, the latter are positioned so that they are substantially transversal to the radial projection 12 and the notch 13.

[0028] The pendular movement means 14 consist of a screw 15 which passes crosswise through the first bushing 7, which has coaxial countersunk openings 16. These openings 16 have initial dimensions smaller than the diameter of the screw 15, so that they are deformed during assembly with the screw 15, resulting in a self-locking action between the screw 15 and the first bushing 7. Moreover, the screw 15 is connected, in such a way that it can be screwed in and out, to the pin 6 which has a threaded through-hole 17.

[0029] The screw 15 is mounted on the bushing 7 and pin 6 before the latter are housed inside the hole 9, in such a way that the screw 15 is completely housed in the hole 9, with one of its ends in contact with an arched inner surface 18 of the hole and, the other end, partially opposite an arched slot 19, passing through the hinge body 2 and on a surface 20 opposite the above-mentioned arched surface 18. In this way, the screw can be turned in both directions and from outside the hinge body 2 (see arrow F1 in Figures 4 and 5) with a known type of tool, obtaining the pendular movement of the pin 6 - bushing 7 unit (see arrows F2 and F3 again in Figures 4 and 5) by moving, or rather, angling, the screw 15 relative to the plane P parallel with the doorframe and intersecting the longitudinal axis Z.

[0030] In the two directions, that is to say, of screwing in and unscrewing, the screw 15 cannot move forwards or backwards along its longitudinal axis and, as a result, allows the angling of the pin 6 - bushing 7 unit through a sliding motion along the surfaces 18 and 20.

[0031] As illustrated in the accompanying drawings, the inner surface 20 of the bushing 7, with the slot 19, has a groove 38 (defining a widening of the bushing hole) which extends over the entire length of the bushing 7. The groove is designed to hold at least the outer part of the head 15T of the screw 15 resting on the surface during the sliding which allows it to be housed in the bushing 7. This device may be preferable, since the head 15T of the screw 15 is normally cup-shaped and, therefore, makes contact with the cylindrical surface 20 only at one tangent point. Therefore, since the head 15T is in an open space in the moment in which it is positioned next to the slot 19, it could move back several tenths until it rests on the edges of the slot, resulting in the possibility of a small amount of play on the screw 15 in the hole 9, which could increase with an increase in the angle of the screw 15 during the pendular movement.

[0032] By giving the groove 38 a well-defined depth and a length at least equal to the length of the head 15T of the screw 15, any play on the screw 15 is eliminated when the latter is in contact with the inner surface 20 and close to the slot 19.

[0033] Instead of working the cylindrical surface 20 of the hinge body 2 in this way, a stabiliser 180 may be used (see Figure 14), inserted between the head 15T of the screw 15 and the inner surface 20.

[0034] As is clearly illustrated in Figure 14, the stabiliser 180 is a matching fit, on one side, with the suitably-shaped head 15T, and on the other, makes contact with the inner surface 20.

[0035] The stabiliser 180 also has a central through-hole 181, designed to allow operation of the screw 15 from the outside. This alternative embodiment may be preferable, since it does not require any working on the inner surface 20 of the hinge body 2 and allows rapid, safe stabilising of the screw 15 inside the hinge body.

[0036] The above-mentioned radial projection 12 has an outer cam profile, for contact with the notch 13, which is arched on three sides so that, during the pendular movement caused by the screw 15, the position of the pin 6 can be maintained along the plane P parallel with the doorframe. The cam profile allows the pin 6 to move along the plane P, since the projection 12 is raised inside the notch 13, recovering the angle α or α' given by the screw 15 to the position of the pin 6 - bushing 7 unit to obtain a relative movement T or T'.

[0037] The above-mentioned hole 9 in the hinge body 2 substantially consists of a first surface 21 in which the notch 13 is made, the above-mentioned second 18 and third 20 arched surfaces, which are opposite one another, and upon which the screw 15 acts, and a fourth, flat surface 22, opposite the first surface 21, with which the bushing 7 remains constantly in contact.

[0038] The centre of the fourth surface 22 has a second, reference notch 23, in which, when the bushing 7 is fitted, a second projection 24 on the bushing engages. The projection is designed to be deformed during the above-mentioned pendular movement. During assembly, this type of reference allows the fitter to insert the pin 6 - bushing 7 unit and screw 15 in the hole 9 more rapidly, with the elements already in the central position.

[0039] Figure 1 also illustrates how the radial projection 12, the notch 13 and the second notch 23 extend along the entire length of both the hinge body 2 and the bushing 7, whilst the second projection 24 extends only along part of the length of the first bushing 7.

[0040] The slot 19, through which the screw 15 can be operated, is then closed with a special anti-tampering plate 30 which also covers the fixing screws on the bracket 4 of the hinge 2, and the upper part of the hinge body 2 is fitted with a relative cover 40.

[0041] Figure 1 also shows how the lower part of the hinge 1 described up to now, that is to say, the second hinge body 3, closest to a tread surface P' (visible in Figure 6), is fitted with second means 111 for adjusting the axial distance, that is to say, the distance along the axis Z between the second hinge body and the first hinge body 2. The relative axial distance between the two hinge bodies 2 and 3 is adjusted, that is to say, the centre to centre distance H (see Figure 8).

[0042] The second axial adjustment means 111 are located between the second hinge body 3 and the second bushing 8, housed in the hole 10, so that in practice they allow said axial adjustment, from the outside, of the distance between the first and second hinge bodies 2 and 3.

[0043] More specifically, as is again shown in Figure 1, the second axial adjustment means 111 consist of the second bushing 8 with an outer portion, labelled 130, which is threaded and can be screwed into the second hinge body 3 which has a matching inner thread 131.

[0044] This connection allows the second bushing 8 to be raised or lowered by simply screwing in or unscrewing the second bushing.

[0045] In a preferred embodiment, the second bushing 8 may have an outer thread 130 which extends over only part of its surface and close to an end collar 120 on the second bushing.

[0046] Again in Figure 1, the second bushing 8 has a slot 132 in its base 133, which is designed to allow the insertion of a tool U (schematically illustrated, being of the known type) for adjusting, through rotation in both directions (see arrow F4), the second bushing about the longitudinal axis Z of the hinge 1. This allows the second bushing 8 to be raised or lowered with the relative screwing in or unscrewing of the second bushing.

[0047] To lock the second bushing 8 in the desired position, the bushing has a pair of notches 134, positioned opposite one another and close to the base 133 of the second bushing 8. During use, these notches 134 engage with a pair of teeth 135 on a cover 136 for closing the second hinge body 3, so as to lock the second bushing 8. Figure 1 illustrates how the second bushing 8 has four notches 134, evenly distributed around the base 133 to facilitate and speed up insertion and locking of the cover 136 from the outside. The two teeth 135 are positioned and locked, through rotation, thanks to a set of grooves 160 inside the second hinge body 3, allowing the teeth 135 to lock the second bushing 8 and, at the same time, to be partially housed in said grooves.

[0048] Figure 10 shows a first alternative embodiment of the second axial adjustment means 111. In this embodiment, the second means 111 consist of a threaded positioning body or plate 137, which can be screwed into the base of the second hinge body 3, the latter having an inner thread 138.

[0049] The centre of the plate 137 has a through-seat 141 designed to allow the insertion of an operating tool U1 (of the known type and, therefore, only schematically illustrated) which can be used to turn the plate 137 in both directions (see arrow F5), thus, after assembly of the hinge, raising or lowering the second bushing 8 along the longitudinal axis Z.

[0050] In this specific case, the second bushing 8 has teeth 142 for locking and positioning, in rotation, distributed evenly over its outer circumference and engaging with seats 143 in the inner surface of the second hinge body 3. These teeth 142 can be used to adjust the pin 6 according to the axis Y perpendicular with the plane P, as described above.

[0051] Figure 11 illustrates another embodiment of the second adjustment means 111. This embodiment envisages the use of a third bushing 112, inserted coaxially between the second bushing 7 and the second hinge body 3 which houses the second bushing 7.

[0052] The third bushing 112 is acted upon by means 113 which move it along the above-mentioned longitudinal axis Z. These means are positioned between the third bushing and the second hinge body 3, so as to vary the position of the third bushing 112 relative to the second hinge body 3 attached to the fixed frame IF.

[0053] In order to obtain this type of movement, the third bushing 112 had a radial projection 114 (see Figures 9 and 11) along its outer circumference, extending longitudinally over a section T of the latter, and engaging in a matching radial cavity 115, longitudinally passing through, and partially opening onto the hole 10 of the second hinge body 3. The suitably threaded cavity 115 allows engagement of the screw movement means 113 (defined by a suitable grub screw 119), acting on the radial projection 114 to move the third bushing 112 away from or towards the second hinge body 3.

[0054] As illustrated in Figures 9 and 11, the radial projection 114 on the third bushing 112 and the radial cavity 115 in the second hinge body 3 have a circular cross-section.

[0055] To allow precision assembly of the hinge 1, and a correct hinge starting position, the hole 10 in the second hinge body 3 for housing the third bushing 112 has an extended edge 117, designed to define a seat which makes contact with and acts as a stop for a collar 118 on the third bushing 112, when the bushing is fully inserted in the first body 2 (see Figure 7).

[0056] A hinge thus structured is assembled using conventional procedures, both on the fixed frame and the mobile frame, whilst the adjustment operations are carried out by moving the screw 15, as described above and as illustrated in Figures 3 to 5, regarding the radial position on the plane P of the upper portion of the pin 6, that is to say, by screwing in or unscrewing the screw 15 which allows the movement T or T' of the pin 6 until it reaches the desired position and is locked there.

[0057] On the second hinge body 3, it is possible to obtain both a radial adjustment on the axis Y perpendicular with the plane P, by moving the position of the second bushing 8 (eccentric), and an adjustment along the vertical axis Z by, in the first embodiment, screwing in or unscrewing the second (threaded) bushing 8 from the base. This substantially lengthens the hinge along the axis Z and raises (or lowers) the mobile frame IM relative to the fixed frame IF.

[0058] As indicated, the adjustment of the centre to centre distance H is effected in the second embodiment illustrated in Figure 10 (thanks to the operation of the plate 137), and in the third embodiment illustrated in Figure 11, thanks to operation of the grub screw 119 (see arrow F6 in Figure 11) in the radial cavity 115 using an appropriate tool and which, pressing against the cylindrical projection 114 of the third bushing 112, allows the third bushing to be raised, thus also raising or lowering the second bushing 8 and the pin 6 thanks to the contact with the collar 120 on the second bushing 8 and directly on the first bushing 7, located on opposite sides of the pin 6 collar 22 (see also arrow F7 in Figure 8). This substantially lengthens the hinge along the axis Z and raises (or lowers) the mobile frame IM relative to the fixed frame IF (see arrow F8 in Figure 6).

[0059] Upon completing all adjustments, the operator may fit the anti-tampering plates 30 and 30' on the brackets 4 and 5 of the hinge 1 to complete its assembly.

[0060] In the embodiments with axial adjustment, it is therefore possible to select continuous adjustment using the grub screw 119 or plate 137, or fixed step adjustment with the threaded bushing 8, the latter taking into account the adjustment along the axis Y which is effected by the second bushing 8.

[0061] To complete this embodiment, Figures 12 and 13 show how the locking means 100 of each of the hinge bodies 2 and 3 consist, as is known, of at least one pair of screws 150 which can be fitted into first through-seats 151 in the brackets 4 and 5. These screws 150 may be locked in second, threaded seats 152 in a corresponding dowel 153 inserted in the frames 154 of the fixed frame IF and the mobile frame IM. These frames (only partially visible) in turn have through-holes 155 for the passage of the screws 150, with a diameter D1 greater than the diameter D2 of the second seats 152.

[0062] In the specific case illustrated, the head 150T of each screw 150 has a countersunk centring profile PS, which engages with a matching countersink in the first seat 151. In addition, the central portion 156 of the shank 157 of each screw 151 has a diameter D3 substantially equal to the diameter D1 of the through-holes 155, allowing the screws to be locked, by interference, in the hole 155 when the screws 151 are screwed into the second holes 152 in the dowel 153. In other words, the portion 156 allows the elimination of the bushing which, as is known, is used for axial locking of the screw in the doorframe.

[0063] This means that one part can be eliminated from the hinge set to be assembled.

[0064] The hinge, therefore, fulfils the stated aims by means of a system for adjusting the hinge on three axes with simple adjustment movements, all effected with the hinge in use and without difficult lifting and subsequent refits.

[0065] Said adjustment is extremely precise and continuous in terms of the positions which can be reached, allowing the fitter a simple, convenient view of the positions of the various hinge adjustment elements (screw on upper hinge body, threaded grub screw or bushings on lower hinge body).

[0066] The hinge as a whole is not made too heavy by a large number of elements, whilst its safety is maintained within the optimum standards for its category.

[0067] Such possibilities for adjustment give this type of hinge a complete structure, and mean that it meets extremely high standards of assembly and performance.

[0068] The system for fixing the hinge in place is extremely practical and safe and, at the same time, has one less element, thus simplifying assembly and reducing production and storage costs.
