DESCRIPTION

The present invention relates to a hinge for doors, windows and the like.

The sector is known to use concealed hinges, which are hidden from view when the door is closed, while they are visible when the door is open or ajar.

This type of hinge is usually composed of a first portion of the hinge connected to a frame, and of a bracket made of at least a first and a second component, mutually sliding and the second of which can be connected to the door, in such a way as to allow adjustments of the door with respect to the frame.

The hinges of the known art however have a plurality of drawbacks.

In particular, during assembly, the first portion of the hinge is initially connected to the frame, while the second sliding component is fixed to the door.

In a subsequent step, the second sliding component, mounted on the door, is connected to the first sliding component.

However, this operation is usually difficult to carry out as it implies an alignment of the fastening means, for example screws, present on the sliding components.

It will be well understood how the connection of the sliding elements is made complex by the weight of the door or the window so that, especially in the case of armored or security doors, the work of more than one operator is required to complete the assembly, with a consequent increase in the time required for assembly and the number of operators to be employed.

The present invention therefore has the objective of solving the drawbacks of the known art and, in particular, the aforesaid ones.

This object is achieved by means of a hinge according to claim 1. The claims dependent on it show preferred embodiment variants.

The object of the present invention will now be described in detail, with the help of the attached tables, in which:

Figure 1 shows a sectional view of a frame-door assembly comprising a hinge object of the present invention according to a possible embodiment, in which the portions with continuous line concern a bracket in a closed configuration, while the dashed ones are relating to an opening configuration of the same;

∠Figures 2 to 4 illustrate perspective views according to different angles of a variant of the hinge, in which the bracket is arranged in the closing configuration;

- figure 5 represents a perspective view of the hinge of figure 2, in which the bracket is arranged in the opening configuration;

- figure 6 shows a view of a portion of a bracket according to the invention, according to the variant of figure 5;

∠’figure 7 shows the bracket of figure 6 partially in section along the VII-VII plane; - figure 8 represents a front view of a further portion of the bracket of figure 2. With reference to the aforementioned tables, with the reference number 1 a hinge for doors, windows and the like is distinguished in its entirety , which can be associated with a door frame 2, 17.

Preferably, the hinge object of the invention is of the concealed type, ie it is at least partially hidden from view when the bracket is arranged in a closed configuration, which will be discussed shortly.

According to the embodiment shown in Figure 1, the frame 2, 17 identifies inside it a frame compartment 3 in which the hinge 1 is at least partially contained.

According to a further variant, the frame 2, 17 has an opening 18, facing a door threshold, through which the frame compartment 3 communicates with the threshold.

The hinge 1 comprises a first hinge portion 4â € ™, 4â € connectable to the door frame 2, 17, and a second hinge portion or bracket 5, connectable to a door 16 and rotatable with respect to the first hinge portion 4â € ™ , 4â € around an axis of rotation X between a closing configuration of the door, in which the bracket 5 is preferably at least partially hidden from view, and an opening configuration.

In other words, during assembly, the first portion of hinge 4â € ™, 4â € is connected to the door frame 2, 17 so as to be integral with it, while the bracket 5 is connected to the door 16 so as to make it rotatable with respect to frame 2, 17 around the axis of rotation X.

In this way, according to an advantageous embodiment, the bracket 5 remains at least partially hidden from view when it is arranged in the closing configuration, while it is visible and accessible, for example for maintenance operations, when this is in the opening configuration. .

Advantageously, therefore, the aesthetic impact of the hinge according to the invention is considerably reduced.

According to an embodiment, when the bracket 5 is in the closed configuration it is at least partially contained in the frame compartment 3.

According to a further embodiment, when the bracket 5 is in the closing configuration it is at least partially contained in a door space (not shown) identified in the thickness of the door 16.

In other words, in the closing configuration, the bracket 5 can be contained in the frame compartment or in the door compartment, or it can be partially contained in each of the two aforesaid compartments.

Preferably, the hinge 1 comprises a pair of first hinge portions 4â € ™, 4â € spaced along the axis of rotation X so as to axially comprise the bracket 5.

Therefore, according to this embodiment, the rotation axis X and, in this case, the rotation pin 19 around which the rotation of the bracket 5 takes place, are held by the first hinge portions 4â € ™, 4â € in correspondence of two portions of axial ends of the pin 19, as shown for example in Figure 2.

In this way, advantageously, the hinge according to the invention can be used for moving doors of any weight and material, for example armored or security doors, without fear that their excessive weight may damage their functionality.

According to a preferred embodiment variant, the pair of first portions 4â € ™, 4â € is mechanically connected by means of a connecting cord 13 extending substantially parallel to the axis of rotation X.

This bead 13, in addition to performing a function of structural stiffening of the hinge, further acts, for the embodiments which provide it, as a means of end-of-stroke for the bracket 5, as will be illustrated below.

According to a further preferred variant, the connecting seam 13 has, transversely to the axis of rotation X, a radially decreasing profile, for example wedge-shaped.

In the embodiment illustrated in Figure 4, the connecting cord 13 has a surface 13â € ™ facing the bracket which acts as a contact surface for the bracket 5, when this is arranged in the limit opening configuration.

The bracket 5 is made up of a first 6 and a second bracket portion 7 sliding reciprocally so as to allow adjustments of the second bracket portion 7 with respect to the first 6 in a plane parallel to the exposed surface of the door.

Therefore, in the conditions of use, since the first portion of bracket 6 is integral with the frame in a plane parallel to the exposed surface of the door, and the second portion of bracket 7 being integral with the door, the adjustment of the second portion of bracket 7 with respect to the first 6 allows you to adjust the positioning of the door with respect to the frame in a plane parallel to the surface of the door.

In other words, by adjusting the mutual positioning between the first 6 and the second portion of bracket 7, the positioning of the door with respect to the frame is adjusted, and for example to prevent it from crawling on the ground, or not adhering sufficiently to a gasket (not shown ) to avoid drafts or eddy currents in an environment.

Furthermore, the first portion of the bracket 6 is shaped in such a way as to identify a seat 8 for sliding reception of the second portion of the bracket 7.

In other words, the first portion of the bracket 6 is shaped so as to contain in the seat 8, in a translatable manner, at least a part of the second portion of the bracket 7.

This characteristic is of particular innovation with respect to the hinges of the known art, as it allows a considerable saving of time and labor during the assembly of a door to its frame.

In fact, during assembly, the second portion of bracket 7, associated with the door, is received in a stable manner in the seat 8, so that the engagement of any fastening means between the first and second bracket portion is simplified.

Preferably, the first bracket portion 6 is adapted to support the second bracket portion 7.

In other words, in the absence of further fixing means, the second bracket portion 7 is suitable for remaining contained in the seat 8, therefore supported by the first bracket portion 6.

In this way, advantageously, the assembly of the door to the frame can be carried out by a single operator even in the case of doors of considerable weight.

Preferably, the hinge 1 also comprises a retaining element 9, connected to the first portion of the bracket 6 and spaced from it in a direction orthogonal to the exposed surface of the door so as to identify, with the first portion of the bracket 6, the seat 8 for acceptance.

Even more preferably, the first portion of bracket 6 and the retaining element 9 are in one piece.

In fact, according to an advantageous embodiment, the holding element 9 is a folded part of the bracket portion 6.

In other words, according to this embodiment, the first portion of bracket 6 and the retaining element 9 are molded as a single component, after which the retaining element 9 is flexed so as to identify the seat 8 with the first portion of the bracket 6.

According to a preferred embodiment variant, the first portion of bracket 6 and the holding element 9 are connected by means of a structural lightening 10.

In other words, the first portion of the bracket 6 and the retaining element 9 are separated by the structural lightening 10, at which the thickness of the material is reduced, so that the bending operation following the molding is facilitated.

In particular, the lightening 9 looks like a folded flap.

Preferably, the hinge 1 further comprises adjustment means and means for fixing the mutual positioning of the first 6 and second bracket portion 7.

According to an embodiment, the fastening means comprise screws and / or bolts, which are tightened after the desired positioning between the first 6 and the second bracket portion 7 has been identified.

In the embodiment illustrated in figures 7 and 8 the fixing means, comprising for example a screw (not shown), engage a first fixing hole 20 of the first bracket portion 6, pass through a second fixing hole 21 of the second bracket portion bracket 7 (which is engaged in the seat 8) and a third fixing hole 22 of the first portion of the bracket 5, arranged on the retaining element 9, at the outlet of which they engage a nut screw 23.

Thus, the screw head is conveniently accessible to a user when the bracket is in the open configuration.

Advantageously, furthermore, approaching the head of the screw during fixing, the mother screw 23 pushes the retaining element 9 against the second portion of the bracket 7, increasing the contact surface with it, therefore the reliability of the fixing.

In other words, according to this embodiment, the first portion of the bracket 6 and the holding element 9 tighten the second portion of the bracket 7 to each other, in a sort of vice.

According to a further variant, the second fixing hole 21 of the second bracket portion 7 has a passage section higher than the holes 20, 22 with which it communicates, so that the screw that passes through it is freely movable in the free space of the its section, in such a way that the first and second bracket positions can assume the desired reciprocal positions.

In this way, advantageously, the movement of the second bracket portion 7 with respect to the first 6 is not impeded by the fixing means which pass through these components.

According to an embodiment, the aforesaid fastening system is devoid of a nut screw 23, the thread for the screw being made directly in the third fastening hole 22 of the retaining element 9.

According to a preferred variant, the adjustment means comprise at least a first adjustment hole or slot 11 made in the first bracket portion 6, at least a second adjustment hole or slot 12 made in the second bracket portion 7, said first 11 and second hole 12 having lumens at least partially overlapped so as to be engageable by a common tool.

In other words, during the adjustment, the first 11 and the second adjustment hole 12 are at least partially superimposed in such a way as to be engaged by a single tool, for example a screwdriver.

To carry out this adjustment, the handle end of the screwdriver is moved by a user acting as a lever for the portion of the screwdriver engaged in the adjustment holes, thus aligning / misaligning the holes according to different desired adjustments, consequently making the first portion translate of bracket than the second.

Advantageously, therefore, the adjustment means are constructed in a simple and reliable manner.

According to an embodiment, the first adjustment hole 11 has a countersunk profile in the direction of insertion of the tool.

In this way, advantageously, the first adjustment hole 11 allows the tool to reach angles higher than the use of a cylindrical hole, increasing the possibility of adjusting the adjustment means.

Preferably, the first adjustment hole 11 has a different shape and / or a different lumen section with respect to the second adjustment hole 12.

For example, in the embodiment shown in Figure 3, the first circular adjustment hole 11 has a larger section than the second adjustment hole 12, which is square instead.

Preferably, the radially innermost part of the first portion of the bracket has at least a first 6â € ™ and a second section 6â € which extend over distinct and incident surfaces, identifying between them a longitudinal line of discontinuity 14.

According to an advantageous embodiment, the angle identified between the first 6 'and the second segment 6', measured as illustrated in figure 6, is between 0.1 and 20 sexagesimal degrees and, preferably, between 1 and 10 degrees.

Advantageously, the opening angle of the bracket, between the closing configuration and the opening limit configuration, is thus further widened, so that this angle can reach angles greater than 120 sexagesimal degrees.

Even more preferably, the hinge 1 also comprises end-of-stroke means suitable to act as a stop for the bracket 5, when this is arranged in the limit opening configuration.

In fact, in the hinges known in the art, when the bracket reaches the limit opening configuration, corresponding to the maximum opening position of the door, it goes against a portion of the frame, deforming it inappropriately bump after bump.

Advantageously, however, the hinge according to the invention has end-of-stroke means suitable for absorbing the energy coming from the opening of the door, so that the condition of the frame is preserved.

Preferably, the end-of-stroke means comprise an axial portion of the first portion of the hinge 4â € ™, 4â €, which extends from this along the axis of rotation X in such a way as to act as a stop for the bracket 5, when this It is arranged in the open limit configuration.

Even more preferably, the axial portion of the first hinge portion 4â € ™, 4â € includes at least partially the connecting cord 13.

Furthermore, according to an advantageous embodiment, the stop means also comprise the longitudinal discontinuity line 14.

In fact, as illustrated in figure 5, when the bracket 5 reaches the opening limit configuration, the longitudinal line of discontinuity 14 is suitable to abut the connection bead 13.

In particular, as previously mentioned, the surface 13â € ™ of the cord 13 facing the bracket 5 is shaped in such a way as to constitute an abutment surface for the bracket 5.

Preferably, the surface 13â € ™ of the bead 13 is complementary to the conformation of the longitudinal line of discontinuity 14, so as to ensure a high support surface between the two components, and thus to be able to distribute the energy deriving from the ™ impact on a larger surface.

The present invention also relates to an assembly 15 comprising a door frame 2, 17, which identifies a frame compartment 3 facing a door threshold, and a hinge 1, according to any of the previous embodiments, connected to the frame 2, 17.

This hinge is suitable to be received in the frame compartment 3.

Lastly, the present invention relates to an assembly comprising a door identifying a door compartment facing, when this is closed, a door frame, and the hinge 1 described above, connected to the door.

Furthermore, the hinge is suitable for being placed in the doorway when the door is closed.

Innovatively, the first portion of the bracket is shaped in such a way as to identify a seat for the sliding reception of the second portion of the bracket.

In this way, the assembly of a door to its frame allows a considerable saving of time and labor since the correct positioning between the two portions of the bracket is guaranteed by the presence of a special seat.

To the embodiments of the hinge and of the aforesaid assembly, a person skilled in the art, in order to meet specific needs, could make variations or replacements of elements with other functionally equivalent ones.

These variants are also contained in the scope of protection as defined by the following claims.

Furthermore, each variant described as belonging to a possible embodiment can be made independently of the other variants described.
