Description

This utility model relates to a three-axis countersunk hinge for doors and / or openable furniture parts.

There are various types of hinges used to connect a door separating two rooms (or an opening piece of furniture) with an appropriate jamb, so that the specified door or piece of furniture can rotate around an imaginary axis of rotation to provide access to the space on the other side of the door (or part to be opened) furniture).

In recent years, hidden hinges have become more widespread, that is, hinges that are completely hidden from view on both sides of a door or an open piece of furniture when the latter are closed.

Essentially, these hinges contain two fasteners (one of which is recessed into a door or an open piece of furniture, for example, at its outer edge, and the other is recessed into a jamb), connected to each other by levers articulated to one degree or another and providing them moving relative to each other between two limit positions corresponding to the open and closed positions of a door or an open piece of furniture. In the closed position, the two fasteners are facing each other, and the connecting levers are pulled into the cavities made in the fasteners themselves, so that when the door or the furniture piece to be opened is closed, the hinge is completely hidden between the door or the furniture piece to be opened and the corresponding jamb.

In the first configuration, the articulated levers are made in the form of one part and have a first end pivotally articulated with one fastener and a second end that is slidably mounted in a guide made in the other fastener. These levers are also pivotally connected to each other between the ends to form a “five-point joint” (three pivoting rods, two of which are fixed and one movable, plus two rods that can slide in the guides). Due to the mechanical connection obtained in this way and the possibility that one end of the levers can slide in the interior of the corresponding fastener, these levers can rotate relative to each other and provide the complex rotary-translational movement required in the structure, in which the hinges are fully recessed and hidden from the gaze so that you can open and close the door or openable piece of furniture.

In another configuration, both ends of the levers are pivotally connected - the first to one fastener and the second to the other fastener. Another degree of freedom is ensured due to the fact that each lever contains at least two elements, which in turn are pivotally attached to each other at a common end. In addition, these levers are also pivotally connected to each other by a common axis located between the ends of one of the lever elements. This design forms a “seven-point joint” (since there are 7 pivot axes between the jointed levers and between the levers and fasteners), in which the levers can rotate relative to each other and (due to mechanical connection with each other and parts of the loop) they can provide complex rotary - translational movement necessary for opening and closing a door or an opened part of a furniture in a configuration in which the hinges are completely deepened and hidden from view. Despite the fact that the “seven-point joint” requires increased complexity of the design of the levers, nevertheless, it provides the ability to reduce the thickness of the fasteners when they are buried in the door or in the jamb, without requiring the depth required for the slide rails in the solution with "Five-point joint."

For all hinges of this type, there is a problem of adjusting the position during and after the assembly of the door or opening part of the furniture. This problem is solved in several ways, more or less complex, some of which consist in dividing at least one of the fasteners into two parts - one attached to the door and the second, moved in a different way relative to the attached part. Thus, between the attached parts of the fasteners and the corresponding movable parts, adjusting devices are arranged and distributed in various more or less complicated ways. In many cases, in order to obtain such a result (at least approximately) of adjustment along all three axes of the spatial coordinate system without burdening the production of loops by excessive costs and complications, the design of these loops is performed with grooves or slots oriented in the direction of adjustment, with a series of screws that can simply be loosened to allow manual movement of adjustable parts along slots or grooves.

However, the adjustments that can be made with these systems are laborious and sometimes inaccurate.

Thus, the purpose of this utility model is to create a countersunk hinge for doors and / or openable furniture parts, which is adjustable in three axes and which, despite the restrictive condition associated with the complexity of the hinge, allows simple and precise adjustments in all three axes with the simultaneous creation of a structure, the thickness of which, in the sense of the depth of the fastening elements, can be easily limited if necessary.

Accordingly, this utility model achieves these and other goals, which are more obvious from the following description, by means of a hidden hinge for doors and / or openable furniture parts, which is adjustable in three axes and has the structural and functional characteristics set forth in the independent claim of the utility model, and additional options for its implementation are given in dependent clauses.

According to the drawings, a countersunk hinge, adjustable in three axes, for doors and / or openable furniture parts in accordance with a utility model, comprises first and second fasteners 1a, 1b, one of which can be recessed into a door or an open part of the furniture, and another may be buried in a jamb. The first and second fasteners 1a, 1b are connected to each other by several levers 2, 3 with the possibility of their relative movement, which ensures the opening and closing of the door and / or openable furniture. In the context of this description and the paragraphs of the attached utility model formula, the term “several” means the number of objects greater than or equal to 2.

Said levers 2, 3 comprise first and second levers 2, 3, each of which has first and second parts 20, 21; 30, 31.

The first part 20 of the first lever 2 has a first end 22a articulated to the first fastener 1a, and a second end 22b articulated to the first end 23a of the second part 21 of the first lever 2. The second end 23b of the second part 21 of the first lever 2 is pivotally attached to the second fastener 1b. The axes of all respective hinge rods 24a, 24b, 24c extend parallel to the vertical axis Z.

The first part 30 of the second lever 3 has a first end 32a articulated to the second fastening element 1b, and a second end 32b articulated to the first end 33a of the second part 31 of the second lever 3. The second end 33b of the second part 31 of the second lever 3 is pivotally connected to the first fastener 1a. The axes of all corresponding hinge rods 34a, 34b, 34c extend parallel to the vertical axis Z.

The second part 21 of the first lever 2 and the second part 31 of the second lever 3 are pivotally connected to each other at an intermediate point located between their ends 23a, 23b; 33a, 33b. The axis of the corresponding hinge rod 4 runs parallel to the vertical axis Z.

Thus, this loop has a seven-point joint design with three rods for each lever plus one common rod for both levers.

Even if two levers are always indicated in this description, it should be understood that all the considerations set forth herein can be easily extended to the case in which there are three or more levers, unless specific embodiments are specifically mentioned.

The first fastening element 1a on its opposite sides along the vertical axis Z has corresponding flat flanges 10a, 11a lying in the respective planes 12a, 13a that are parallel to each other and the vertical axis Z.

The flat flanges 10a, 11a of the first fastener 1a are used to fasten the first fastener 1a to the corresponding door or opening piece of furniture, or to the corresponding jamb. For this purpose, as shown, they are made with corresponding holes for the mounting screws.

The first horizontal axis X is defined as the axis perpendicular to the planes 12a, 13a in which the flanges 10a, 11a of the first element 1a lie.

The second fastening element 1b on its opposite sides along the vertical axis Z has corresponding flat flanges 10b, 11b lying in the respective planes 12b, 13b that are parallel to each other and the vertical axis Z.

The flat flanges 10b, 11b of the fastener 1b are used to fasten this element 1b to the corresponding door or opening part of the furniture, or to the corresponding jamb. For this purpose, as shown, they are made with corresponding holes for the mounting screws.

The second horizontal axis X 'is defined as the axis perpendicular to the planes 12b, 13b in which the flanges 10b, 11b of the second fastener 1b lie.

The third horizontal axis Y, in turn, is defined as the axis perpendicular to the vertical axis Z and at the same time parallel to the planes 12b, 13b, in which the flanges 10b, 11b of the second fastening element 1b lie.

Thus, for the second fastener 1b, the Cartesian coordinate system X'YZ is fully defined. To complete the determination of such a coordinate system for the first fastener 1a, an additional axis Y 'can be introduced, which in turn is defined as an axis perpendicular to the vertical Z axis and parallel to the planes 12a, 13a, in which the flanges 10a, 11a of the first fastener 1a lie. Thus, the Cartesian coordinate system XY'Z is also fully defined for the first fastener 1a. The coordinate system XY'Z of the first fastener 1a and the coordinate system X'YZ of the second fastener 1b have a common vertical axis Z.

In the accompanying drawings, the axes defined by the two coordinate systems XY'Z and X'YZ are indicated schematically. 1 and 2, planes 12a, 13a, 12b, 13b in which the flanges 10a, 11a lie; 10b, 11b of the first and second fasteners 1a, 1b are schematically indicated by dashed lines. Further, they coincide with the plane of the drawings in figure 3 and 8 or parallel to it. In addition, they are perpendicular to the plane of the drawing in figure 4, 5, 6, 9a, 9b, 10b.

The terms “closed position” and “open position” referring to a hinge are used to denote the configurations adopted by the hinge when the door or opening part of the furniture is in the closed and open position, respectively.

When the loop is in the closed position, the planes 12a, 13a of the flat flanges 10a, 11a of the first fastener 1a are facing the planes 12b, 13b of the corresponding flat flanges 10b, 11b of the second fastener 1b, i.e. the planes 12a, 13a of the flanges 10a, 11a of the first fastener 1a are not at an angle to the planes 12b, 13b of the flanges 10b, 11b of the second fastener 1b.

When the loop is in an intermediate position between the closed and open positions, the angle formed between the planes 12a, 13a of the flanges 10a, 11a of the first fastener 1a and the planes 12b, 13b of the corresponding flanges 10b, 11b of the second fastener 1b has a value between zero and the target maximum value corresponding to a fully open position.

When the hinge is in the closed position, the first part 20 and at least part of the second part 21 of the first lever 2, as well as at least part of the second part 31 of the second lever 3, are placed in the cavity 14a in the first fastening element 1a, while the first part 30 and at least part of the second part 31 of the second lever 3, as well as at least part of the second part 21 of the first lever 2 are placed in the cavity 14b in the second fastening element 1b. The cavity 14a in the first element 1a and the cavity 14b in the second element 1b have a corresponding open side 15a, 15b and a corresponding farthest inner side 16a, 16b, which are located one after the other when moving, respectively, along the first horizontal axis X or the second horizontal axis X 'directed inwardly into the corresponding fastener 1a, 1b.

The first and second elements 1a, 1b are solved in a structurally defined manner in order to provide adjustment in three axes (or directions) located at right angles to each other. More specifically, the following should be noted.

Each fastener 1a, 1b, first and second, comprises a corresponding outer structure 17a, 17b and a corresponding first movable structure 18a, 18b placed in the outer structure 17a, 17b, which has flat flanges 10a, 11a; 10b, 11b of the respective fasteners 1a, 1b.

The second fastening element 1b also comprises a second movable structure 19b, which, in turn, is placed in the first movable structure 18b.

On the first movable structure 18a of the first element 1a, hinge rods 24a, 34c are arranged, which respectively pivotally connect the first end 22a of the first part 20 of the first lever 2 and the second end 33b of the second part 31 of the second lever 3 to the first element 1a.

Hinge rods 34a, 24c are arranged on the second movable structure 19b of the second fastener 1b, which respectively pivotally connect the first end 32a of the first part 30 of the second lever 3 and the second end 23b of the second part 21 of the first lever 2 to the second element 1b.

This loop further comprises first means for adjusting the position of the first movable structure 18a of the first fastener 1a with respect to the fixed structure 17a of the first fastener 1a, second means for adjusting the position of the first movable structure 18b of the second fastener 1b relative to the fixed structure 17b of the second fastener 1b, third means for adjusting the position the second movable structure 19b of the second fastener 1b relative to the first movable structure 18b of the second element Enta 1b.

This solution provides the ability to adjust the loop on various axes located at right angles to each other.

In accordance with the drawings (in particular, FIGS. 1-5 and 8), the direction of translational movement of the second movable structure 19b relative to the first movable structure 18b of the second fastening element 1b is provided along the third horizontal axis Y. The third adjusting means comprise an eccentric 7, which, being located on the furthest inner side 16b of the cavity 14b in the second fastener 1b, has a pivot axis 70 extending parallel to the second horizontal axis X '. The eccentric 7 is accessible from the open side 15b of the cavity 14b when the hinge is in the open position, and this eccentric acts on the surface parts of the second movable structure 19b of the second fastener 1b and / or on the parts of the second fastener 1b other than the second movable structure 19b. Rotations of the eccentric 7 relative to the axis of rotation 70 in opposite directions determine the movements of the second movable structure 19b of the second fastener 1b in opposite directions along the third horizontal axis Y relative to the first movable structure 18b.

Preferably, the eccentric 7 of the third adjusting means has a round head 71 inserted in the socket 72, made in the farthest inner part 25b of the second movable structure 19b of the second fastener 1b, comprising at least part of the farthest inner side 16b of the cavity 14b of the second fastener 1b.

In a preferred embodiment of the third adjusting means shown in FIGS. 2-5, and in a minor embodiment shown in FIG. 9a, the eccentric 7 of the third adjusting means comprises a round head 71, which, in turn, is a rotary disk with an offset axis 70 turns. A corresponding elongated slot 72 extends along the vertical axis Z, the width of which along the third horizontal axis Y is equal to the diameter of the round head 71.

Along the second horizontal axis X ', the thickness of the round head 71 is less than or equal to the depth of the socket 72.

Preferably, as shown, for example, in FIGS. 5 and 9, the thickness of the round head 71 is equal to the depth of the socket 72. The socket 72 may be through (as in FIG. 5). In the embodiment shown in FIG. 5, the head 71 is adjacent to the farthest inner portion 25b of the second movable structure 19b of the second fastener 1b. In the embodiment shown in FIG. 9a, the head 71 is adjacent to the farthest inner side of the socket 72 itself. Typically, the third adjusting means comprise at least one locking screw 73 acting between the second movable structure 19b of the second fastener 1b and the parts of the second fastener 1b, other than the second movable structure 19b, for securing the latter in place. The locking screw 73 is inserted into a through socket made in the eccentric 7 of the third adjusting means, securing its pivot axis 70 and, when tightened, is pressed against the round head 71. The locking screw 73 is connected to a thread made in the farthest inner part 26b of the first movable structure 18b of the second fastener 1b.

FIGS. 9b and 9c illustrate a possible embodiment of the third adjustment cam 7 in which the round head 71 of the cam 7 is inserted between the farthest inner part 25b of the second movable structure 19b of the second fastening element 1b and the surface 100 of either the corresponding first movable structure 18b or the corresponding fixed structure 17b, placed in an annular socket 72 with an equal diameter, and in the direction of the cavity 14b of the second fastener with a smaller diameter (so as to hold the head 71 in place). An eccentric element 74 extends from the head 71, which, as the head 71 rotates, acts on the inner edges of the groove 75 oriented along the Z axis.

Advantageously, as shown in FIGS. 5 and 6, a prismatic guide joint 8 is provided between the first and second movable structures 18b, 19b of the second fastener 1b along the third horizontal axis Y.

Obviously, this type of connection can also be made in the embodiment shown in FIG.

The eccentric 7 may have a hole made therein for introducing the tool used to actuate the eccentric 7. The drawings show that this hole is made in the head 71 of the eccentric 7.

In the proposed loop adjustment on two axes, and not on one third of the horizontal axis Y, can be obtained in several ways, as described below.

The first movable structure 18a of the first fastener 1a is configured to direct its translational movement relative to the corresponding outer structure 17a along the first horizontal axis X, and the first movable structure 18b of the second fastener 1a is configured to direct its translational movement relative to the corresponding external structure 17b along the vertical axis Z (as in the loop embodiment shown in FIGS. 1-7), or the first movable structure 18a of the first fastener element 1a is configured to direct its translational movement relative to the corresponding external structure 17a along the vertical axis Z, and the first movable structure 18b of the second fastening element 1b is configured to direct its translational movement relative to the corresponding external structure 17b along the second horizontal axis X '(as in the embodiment performing the loop shown in Fig.8).

Here, the first of two embodiments of a loop adjustable in two axes, and not in one third of the horizontal Y axis, is discussed, in particular, the loop embodiment shown in FIGS. 1-7.

In this embodiment, the first movable structure 18a of the first fastener 1a is configured to direct its translational movement relative to the corresponding outer structure 17a along the first horizontal axis X, and the first movable structure 18b of the second fastener 1b is configured to direct its translational movement relative to the corresponding external structure 17b along the vertical axis Z. In this case, the first adjusting means act along the first horizontal oh X-axis, and second adjusting means act along a vertical axis Z.

More specifically, preferably the second adjusting means comprise a suitable cam 6, which can be accessed at least when the loop is in the open position, which has a pivot axis 60 parallel to the second horizontal axis X 'and which acts on the surface parts of the first movable structure 18b and / or parts of the fixed structure 17b of the second fastener 1b. Rotations of the eccentric 6 about the rotation axis 60 in opposite directions define the displacements of the first movable structure 18b of the second fastener 1b in opposite directions along the vertical axis Z with respect to the corresponding fixed structure 17b.

In this way, adjustment along the vertical Z axis can be easily and accurately performed. More specifically, the eccentric 6 of the second adjustment means has a round head 61 inserted in the socket 62 formed in a portion of the first movable structure 18b of the second fastening element 1b.

Preferably, as shown in FIGS. 1-5, the eccentric 6 of the second adjusting means comprises a round head 61, which, in turn, is a rotary disk with an offset axis of rotation 60. Along the third horizontal axis Y there passes a corresponding elongated socket 62, the width of which along the vertical axis Z is equal to the diameter of the head 61.

Along the second horizontal axis X ', the thickness of the round head 61 is less than or equal to the depth of the corresponding socket 62 (preferably equal to it).

Typically, the second adjusting means comprise at least one locking screw 63 acting between the first movable structure 18b of the second fastener 1b and the parts of the fixed structure 17b of the second fastener 1b to secure the first movable structure 18b in place.

The locking screw 63 is preferably inserted into the through socket made in the eccentric 6 of the second adjusting means, with its axis of rotation 60 secured and tightened to the round head 61 when tightened. Under the socket 62 of the head 61 of the eccentric 6 of the second adjusting means, the first movable structure 18b of the second fastening element 1b made with a hole 600 extended along the vertical Z axis, thanks to which the first movable structure 18b can move along the vertical Z axis, while the shaft of the locking screw 63 does not remain odvizhnym.

The first movable structure 18b of the second fastening element 1b on its opposite sides along the vertical axis Z has corresponding flat flanges 27b, 28b located in sockets made in the corresponding fixed structure 17b. The eccentric 6 of the second adjusting means is located in one of the flanges 27b, 28b of the first movable structure 18b of the second fastening element 1b.

In general, an additional locking screw 63 'may be provided, acting between the first movable structure 18b of the second fastening element 1b and the corresponding fixed structure 17b to secure the first movable structure 18b in place. More specifically, as shown in FIGS. 1-4, additional locking screws are inserted into respective holes 600 'elongated along the vertical axis Z. When the additional locking screws are tightened, their heads are pressed against the parts of the first movable structure 18b of the second fastening element 1b. The drawings show that these parts are made by slightly expanding the elongated holes 600 'at the screw heads 63' to provide them with a supporting surface.

The eccentric 6 may have an opening therein for introducing the tool used to actuate the eccentric 6. The drawings show that this hole is made in the head 61 of the eccentric 6.

10a, 10b, and 10c illustrate a possible embodiment of the second adjusting means cam 6, in which a round head 61 of the cam 6 is inserted between a part of the first movable structure 18b of the second fastening element 1b and the surface 101 of the corresponding fixed structure 17b, placed in the annular socket 62 with equal diameter, and in the direction of the cavity 14b of the second fastener with a smaller diameter (so as to hold the head 61 in place). An eccentric element 64 extends from the head 61, which, as the head 61 rotates, acts on the inner edges of the groove 65, oriented along the vertical axis Z. If necessary, the eccentric 6 on the side opposite to the element 64 may have an additional protrusion 66 for installing the tool used to facilitate actuating the eccentric itself 6.

Regarding the adjustment of the loop along the additional axis, which differs from the adjustments along the vertical Z axis and the third horizontal Y axis, in the case of the embodiment shown in FIGS. 1-7, the first adjusting means comprise at least one adjusting screw 5, the axis of which is parallel the first horizontal axis X and which is connected by its thread to the first movable structure 18a of the first fastener 1a, and its end opposite the head is held by the fixed structure 17a of the first crepe element 1a, allowing the adjusting screw 5 to rotate about its axis to prevent it from translating along the first horizontal axis X. Rotating the adjusting screw 5 around its axis in opposite directions sets the first movable structure 18a of the first fastener 1a to move in opposite directions along the first horizontal axis X with respect to the corresponding fixed structure 17a.

The first movable structure 18a of the first fastener 1a on its opposite sides along the vertical axis Z has corresponding flat flanges 27a, 28a placed in sockets made in the corresponding fixed structure 17a.

The adjusting screw 5 of the first adjusting means is connected to one of the flanges 27a, 28a of the first movable structure 18a of the first fastening element 1a, while the first adjusting means comprise another identical adjusting screw 5, which is connected to the other of the flanges 27a, 28a of the first movable structures 18a of the first fastener 1a.

Here we discuss the second of two loop options, adjustable in two axes, and not in one third horizontal Y axis, in particular, the loop option shown in FIG.

In explaining this embodiment, if necessary, reference will also be made to FIGS. 4 and 5 in that part of the drawings, which also applies in this case.

In this embodiment, the first movable structure 18a of the first fastener 1a is configured to direct its translational movement relative to the corresponding outer structure 17a along the vertical axis Z, and the first movable structure 18b of the second fastener 1b is configured to direct its translational movement relative to the corresponding external structure 17b along the second horizontal axis X '. In this case, the first adjusting means act along the vertical axis Z, and the second adjusting means act along the second horizontal axis X '.

The first adjusting means comprise a corresponding eccentric 5a, access to which is possible at least when the loop is in the open position, which has a pivot axis 50 parallel to the first horizontal axis X, and which acts on the surface parts of the first movable structure 18a and / or parts of the fixed structure 17a of the first element 1a. Rotations of the eccentric 5a about the rotation axis 50 in opposite directions determine the displacements of the first movable structure 18a of the first fastener 1a in opposite directions along the vertical axis Z with respect to the corresponding fixed structure 17a.

The eccentric 5a of the first adjusting means has a round head 51a inserted in the socket 52a, made in part of the first movable structure 18a of the first fastening element 1a.

The eccentric 5a of the first adjusting means consists of a round head 51a, which, in turn, is a rotary disk with an offset pivot axis 50a. Corresponding socket 52a

- elongated along the additional horizontal axis Y ', which is perpendicular to the vertical axis Z and parallel to the planes 12a, 13a, in which the flanges 10a, 11a of the first fastening element 1a lie,

- equal in width along the vertical axis Z to the diameter of the head 51a.

Along the first horizontal axis X, the thickness of the round head 51a is less than or equal to the depth of the corresponding socket 52a.

The first adjusting means comprise at least one locking screw 53a acting between the first movable structure 18a and the parts of the first fixed structure 17a of the first fastener 1a for securing the first movable structure 18a in place.

The locking screw 53a is inserted into the through hole made in the eccentric 5a of the first adjusting means, providing its axis 50a of rotation and when tightened is pressed against the round head 51a.

The first movable structure 18a of the first fastener 1a, on its opposite sides along the vertical axis Z, has corresponding flat flanges 27c, 28c placed in sockets made in the corresponding fixed structure 17a. In the first embodiment, shown in solid lines in Fig. 8, the eccentric 5a of the first adjusting means is located in one of the flanges 27c, 28c. In this case, the construction of the eccentric 5a of the first adjusting means is identical to the construction of the eccentric 6 shown in the lower part of the section shown in FIG. 5, which can be considered identical to the section along the secant plane A'-A 'shown in Fig. 8 (with obvious parallels between reference numerals, which in this case refer to the structures available on the first fastener 1a, and do not apply to the structures on the second fastener 1b). Also, in this case, similarly to what is indicated at the bottom of the section shown in FIG. 5 (again with obvious parallels between the reference numbers, which in this case refer to the structures available on the first fastener 1a, and do not apply to the structures on the second fastening element 1b), under the socket 52a of the head 51a of the eccentric 5a of the first adjustment means, the first movable structure 18a of the first fastening element 1a is made with an opening elongated along the vertical axis Z, due to which the first movable structure Tions 18a may move along a vertical axis Z, while a locking screw rod 53a remains stationary.

In the second embodiment, shown by the dashed line in FIG. 8, the first adjustment means cam 5a is located on the farthest inner side 16a of the cavity 14a of the first fastener 1a so as to be accessible from the open side 15a of the cavity 14a when the loop is in the open position. In this case, a description of the cavity 14a and the corresponding open side 15a, as well as the farthest inner side 16a, is also described with reference to FIGS. 1 and 2. The construction of the eccentric is also illustrated in FIG. 11, which, as described in the description of the drawings, is a section the fragment indicated by the dashed line in Fig. 8, perpendicular to both the secant plane A'-A 'shown in Fig. 8, and the orientation axis of the hinge rods (i.e., the Z axis).

The eccentric 5a may have an opening therein for introducing a tool used to actuate the eccentric 5a. On Fig shows that this hole is made in the head 51a of the clown 5a.

10a, 10b and 10c also illustrate a possible embodiment of the first adjusting means cam 5a in which a round head 51a is inserted between a part of the first movable structure 18a of the first fastening element 1a and a surface 101 'of the corresponding fixed structure 17a, with placement in the annular socket 52a with equal diameter, and in the direction of the cavity 14a of the first fastener with a smaller diameter (so as to hold the head 51a in place). An eccentric element 54a extends from the head 51a, which, as the head 51a rotates, acts on the inner edges of the groove 55a oriented along the additional horizontal axis Y '. If necessary, the eccentric 5a on the side opposite to the element 54a may have an additional protrusion 56a for mounting the tool used to facilitate the actuation of the eccentric 5a itself.

Generally speaking, an additional locking screw 53'a may be formed, acting between the first movable structure 18a of the first fastener 1a and the corresponding fixed structure 17a to secure the first movable structure 18a in place. More specifically, as shown in FIGS. 1-4, additional locking screws are inserted into respective holes 500 'elongated along the vertical Z axis. When the additional locking screws are tightened, their heads are pressed against the parts of the first movable structure 18a of the first fastener 1a. The drawings show that these parts are made by slightly expanding the elongated holes 500 'at the heads of the additional locking screws 53a' to provide them with a supporting surface.

Regarding the adjustment of the loop along the additional axis, different from the adjustments along the vertical Z axis and the third horizontal Y axis, in the case of the embodiment shown in Figs. 8 and 11, the second adjusting means comprise at least one adjusting screw 6a, the axis of which is parallel the second horizontal axis X 'and which is connected by its thread to the first movable structure 18b of the second fastening element 1b, and its end opposite the head is held by the fixed structure 17b of the second cre of the fastener element 1b with the rotation of the adjusting screw 6a around its axis with the prevention of its translational movement along the second horizontal axis X '. Rotations of the adjusting screw 6a about its axis in opposite directions determine the movements of the first movable structure 18b of the second fastener 1b in opposite directions along the second horizontal axis X 'relative to the corresponding fixed structure 17b.

The first movable structure 18b of the second fastening element 1b on its opposite sides along the vertical axis Z has corresponding flat flanges 27d, 28d placed in sockets made in the corresponding fixed structure 17b. The adjusting screw 6a of the second adjusting means is connected to one of the flanges 27d, 28d of the second movable structure 18b of the second fastening element 1b, while the second adjusting means comprise another identical adjusting screw 6a, which is connected to the other of the second movable flanges 27d, 28d structures 18b of the second fastener 1b.

The connection structure between the fixed structure 17b of the second fastening element 1b and the corresponding first movable structure 18b (as well as the structure of the corresponding adjusting screw 6a, or the corresponding adjusting screws 6a) in the embodiment shown in Fig. 8 is identical to the design illustrated in the upper and lower parts the section shown in Fig. 4, which can be considered identical to the section along the secant plane B'-B 'shown in Fig. 8 (with obvious parallels between the reference position and that in this case relate to the structure having the second fastening member 1b, and do not belong to the structures on the first fastening element 1a).

Let us return to the hinge structure as a whole, regardless of the above embodiments, basically, the first movable structure 18a, 18b of one (or each) of the fastening elements 1a, 1b can be made in the form of two inserts located inside the corresponding fixed structures 17a, 17b on opposite sides along the vertical Z axis and attached to each other in various ways (even, for example, either by means of articulated levers, or, if possible, by means of a second movable structure 19b). Preferably, the fixed structure 17a, 17b, the first movable structure 18a, 18b, and the second movable structure 19b are all in the form of enclosed bodies. As shown in the drawings, housing data in a plane containing a first horizontal axis X and a vertical axis Z (or in a plane containing a second horizontal axis X 'and a vertical axis Z) have a substantially C-shaped cross section, which in some cases may be made with corresponding flat flanges at their ends along the vertical axis Z.

This utility model provides significant benefits.
