Description

Adjustable hinge for doors and windows

Technical Field

The present invention relates to an adjustable hinge for doors and windows.

In the field of construction, the expression "door and window" generally denotes the combination of a frame to be anchored to the building masonry and of a mobile element, generally a sash of a door or window, constrained to the frame by means of suitable hinges.

Background

The frame has a rigid and fixed perimeter structure that is fixed to the wall by polyurethane foam, screws and dowels, typically passing through the mating frame. Each frame acts as a support for one or more mobile elements, allowing opening and closing by means of the hinges described above.

To enable accurate adjustment of the door or window, the hinge is typically adjustable both longitudinally and transversely.

Such an adjustment may compensate for any deformation of the frame and/or sash and may even compensate for any inaccurate mounting of the latter.

More specifically, the longitudinal adjustment allows to adjust the mutual position of the frame and sash along the rotation axis of the hinge, whereas the transverse adjustment allows to adjust the mutual position of the frame and sash on a plane perpendicular to the rotation axis of the hinge. In particular, there are prior art hinges that can be adjusted according to three axes at right angles to each other, wherein the lateral adjustment allows to adjust the mutual position of the frame and the sash along a first direction lying on a plane perpendicular to the rotation axis of the hinge and parallel to the wall on which the sash is opened, and along a second direction lying on a plane perpendicular to the rotation axis of the hinge and at right angles to the wall on which the sash is opened.

An example of a hinge adjustable in three axes at right angles to each other is known in italian patent No. 1304490 by the same applicant. The hinge allows accurate adjustment of the door or window, but it is rather complex in terms of production and therefore high in cost, as well as in terms of assembly and subsequent adjustment.

Another prior art solution, in which the adjustment of the eccentric pin in two horizontal axes at right angles to each other is produced by an adjustment device, is described in the patent document EP1672155 of the same applicant, where the hinge part has no wings.

These adjustment means comprise a plurality of radial notches formed uniformly around the first portion of the pin and close to a circular plate for separating the two portions forming the pin.

These notches may be received in associated radial grooves formed on the upper end of the body for receiving the pin and in associated holes for receiving the pin to define, in use, a plurality of separate positions for adjusting the second portion of the pin by lifting the pin, rotating the adjustment pin and thus by a new receptacle in the body.

However, this type of regulation has several drawbacks.

The adjustment with the notch is discrete and therefore in some cases the positioning obtained is a compromise, rather than the proper and correct position of the hinge with respect to the door or window.

The adjustment operations always require lifting and then lowering the pin, making these operations tedious and laborious, since it is also necessary to remove/lift the upper, winged body of the hinge.

The notch does not always have a reference capable of displaying any maximum and minimum range of the adjustment axis, making the work of the operator difficult.

Disclosure of Invention

The object of the present invention is to provide an adjustable hinge for doors and windows that is simple in structure and therefore easy and inexpensive to manufacture, and that has a quick and precise adjustment.

Said object is fully achieved by an adjustable hinge for doors and windows, characterized in the appended claims.

Detailed Description

With reference to fig. 1, reference numeral 1 indicates as a whole an adjustable hinge for doors and windows.

The hinge 1 comprises a first cylindrical body 2 provided with a first wing 3 in cantilever form for fixing to a frame (not shown), and a second cylindrical body 4 provided with a second wing 5 in cantilever form for fixing to a movable sash (not shown).

The door or window may comprise a door or window with one or more sashes.

The cylindrical bodies 2 and 4 of the hinge are fixed to the frame and the corresponding channels of the movable sash of the door or window by means of plates 6 and screws 7.

The cylindrical bodies 2 and 4 are rotatably connected to each other by a hinge pin 8. The pin 8 may be made of different materials depending on the application.

The pin 8 has a first end section 9 located inside a first seat 10 formed in the first cylindrical body 2 and a second end section 11 inserted inside a second seat 12 formed in the second cylindrical body 4.

In the following, the first seat 10 is used to indicate the combination of the first seat 10 and an anti-friction bush 17 (described below) on which the first segment 9 of the pin 8 is housed so as to be interposed between the first segment 9 and the first seat 10.

The

segments

8 and 9 are generally cylindrical, as are the

seats

10 and 12 and the anti-friction bushings 17.

The

end segments

9 and 11 extend longitudinally according to directions that are parallel and offset to each other and that extend at right angles to and face each other with respect to a preferably centrally located intermediate disc 13 of the pin 8.

In particular, the disc 13 has a circular shape. Furthermore, the pin 8 is preferably made in a single piece.

One of the two

end segments

9 and 11 can be locked in the

respective seat

10, 12, while the other is free to rotate in the

respective seat

12, 10.

Preferably, the end segment 11 connected to the movable sash can be locked in the respective seat 12 by means of reversible locking means 14, while the end segment 9 connected to the fixed frame can rotate freely in the respective seat 10.

In particular, as shown in fig. 3, the end section 9 has an end 15, in particular conical, longitudinally recessed, which rests on a projecting bottom seat 16 of the above-mentioned friction-reducing bush 17 positioned in the seat 10.

The contact between the end 15 and the seat 16 is limited to a circular crown. This, together with making the bushing 17 of high-tech high-molecular polymer, advantageously reduces friction and facilitates the free rotation of the pin 8 inside the bushing 17.

In particular, this combination between the longitudinal hollow end 15 and the seat 16 means that the load (i.e. the weight of the sash) is supported in this position and the particular shape reduces friction in the rotary movement by compensating for the supported load.

The bush 17, together with the pin 8, can be adjusted in height (Z-axis) along the relative longitudinal axis 17a, i.e. in the longitudinal direction of the seat 10, by means of a screw 18 positioned in contact with the bush 17 on the opposite side of the seat 16 and screwed onto the end of the body 2 facing the body 4 after assembly of the hinge 1.

In this way, the relative longitudinal position of the bodies 2 and 4 can be adjusted simply by tightening or loosening the screw 18. Such adjustment allows to adjust the height (Z axis) of the body 4 and therefore of the door or window to which it is fixed, considering that the position of the body 2 is locked on the door or window.

The screws 18 are covered by a cap 19 having a mainly aesthetic effect.

In addition to the height adjustment described above, there is a completely independent second adjustment of the relative position of the bodies 2 and 4 on a plane at right angles to the axis 17a of the bush 17 (compensation adjustment of the X and Y axes).

This second adjustment is achieved by the eccentric coupling of the bodies 2 and 4 and results from the position of the pin 8 locked within the body 4.

For this purpose, the lockable end segment 11 has a single element 20 for displaying the adjustment and limitation of the eccentricity of the pin 8.

The single element 20 projects radially from a side surface 21 of the second end segment 11 of the pin 8.

The single element 20 engages, in use, in a radial slot 22 (with horizontal extension) which forms a radial outlet in the second cylindrical body 4 towards the outside of the relative seat 12 of the second end segment 11.

The adjustment and limiting element 20 is visible to the operator in use through the radial slot 22 to allow the rotary movement of the display pin 8, i.e. of its two

segments

9 and 11, about the respective longitudinal axes, so as to keep the pin 8 fully housed within the first and

second seats

10 and 12 during its adjustment of the angular position.

In other words, the display element allows the operator to directly obtain the angular position for the (visual) adjustment of the pin 8 with respect to the locking seat 12.

Thanks to the display element, this adjustment operation can be carried out without having to lift the pin 8 from the

respective seats

10 and 12, and allows fine adjustment of the eccentricity of the pin 8.

In addition, as described below, the end of the slot 22 represents the maximum adjustment range possible in one direction or the other, so that the position of the display element 20 allows the operator to always see the position adopted by the pin 8.

The adjustment element 20 thus acts as an indicator of the eccentricity of the mutual coupling of the cylindrical bodies 2 and 4.

Elements 20 for displaying the adjustment and limiting quantities are formed radially on the side surface 21 of the end segment 11 that can be locked and facing the radial outlet 22 outside the locking seat 12.

Preferably, the display element 20 is defined by a radial projection 23 of the side surface 21 of the end segment 11 that can be locked.

It should be noted that the projection 23 is located at a position spaced from the disc 13 for separating the two

segments

9 and 11.

Preferably, the radial projection 23 is rod-shaped.

In particular, according to the embodiment shown in fig. 1 to 4, the radial projection 23, which is in the form of a rod, is a fin or vane 24 of flat shape and is integral with the pin 8. In particular, the projection 23 is preferably located substantially midway along the segment 11.

In order to be able to insert the segment 11 into the seat 12, the latter has at least one longitudinal groove 25 in which the projection 23 (for example, the fin 24) can slide.

The longitudinal groove 25 is formed at least along a portion of the cylindrical body 4 into which the segment 11 of the pin 8 is inserted during assembly (and also in the case of removal).

Referring to fig. 4 and 6, the groove 25 may be formed in different sizes.

The dimensions of the grooves 25 shown in fig. 4 are equal to the dimensions of the fins 24.

The size of the grooves 25 shown in fig. 6 is larger than the size of the fins 24.

In this aspect, the groove 25 has a circular arc shape and is larger than the fin 24.

According to the embodiment shown in fig. 5, the rod-like radial projection 23 is defined by a pin 26 fixed in a hole 27 formed in the end segment 11. The pin 26 may have a generally cylindrical shape as shown in fig. 5, or it may have a flat shape. In this case, the projection 23 is also preferably located approximately midway along the segment 11. In this case, however, the grooves 25 may not be present, as shown in fig. 5 and described in more detail below.

In both cases, the radial slot 22 faces the hollow 28 of the body 4 in which the locking seat 12 is formed. The hollow 28 is defined by an open sector of the body 4 that places the locking seat 12 in radial communication with the outside. This opening sector, obtained for example by removing material, may extend over the entire height, that is to say it may affect the body 4 completely between the two longitudinal ends of the body 4, or, as shown in detail in figures 4 and 5, may involve only the substantially central intermediate longitudinal portion of the body 4 defining the two segments of the partial separation of the cylindrical body 4.

Alternatively, the slot 22 may be formed in the uppermost or lowermost portion of the main body 4.

In any case, the hollow 28 is laterally delimited by two walls 29, each defining a respective end of travel limit for the rotation of the radial projection 23, i.e. of the pin 8 located in the seat 12.

The diagonal angle between the wall portions 29 may be 180 deg. as shown in fig. 4 and 5, or may vary depending on the adjustment range of the pin 8 to be ensured.

In fact, in other words, the hollow 28 can be engaged by the projection 23, allowing the angular adjustment of the pin 8 in the locking seat 12 between two extreme adjustment positions.

The upper free end of the segment 11 of the pin 8 can also be provided with an index scale (not shown) to assist the operator in performing the position adjustment operation of the pin 8 which is then locked in the seat 12 using the locking means 14 described above, which in this case are preferably formed in the form of a pair of grub screws 30 which are screwed into respective holes 31 of the body 4 until the end segment 11 of the pin 8 is intercepted and locked by interference.

The groove 25, if present, serves as a guide for the insertion of the pin 8 into the seat 12 in the "zero" position and as a reference for the "zero" position, for example in the solution shown in fig. 4, without the graduated scale (X and Y axes).

Adjustment can be made by rotating the segment 11 (i.e. the whole pin 8) inside the seat 12 by operating directly on the projection 23 with the pin 8 fully housed in the two

seats

10 and 12.

Alternatively, the head of the pin 8 can be operated, for example by means of an internal hexagonal wrench, engaging a cavity formed on the above-mentioned shaped upper end 32 of the segment 11.

The body 4 may be covered by a cylinder 33 having a primarily aesthetic effect. Barrel 33 may employ a bottom wall portion 34 coupled to and integrally formed with pin 8 and having a side wall portion 35 and a top end cap 36.

A hinge constructed in this way enables the preset purposes to be achieved without affecting the basic structure of the hinge by providing openings on the hinge body and projecting elements on the pin.

The possibility of making the adjustment "visually" allows to quickly obtain the desired position of the sash with respect to the frame without having to lift at least one body of the pin and the hinge during the initial installation and subsequent steps.
