Description

The present invention relates to an adjustable retractable loop.

It is known that hinges are made of specific components used to hinge two elements to each other, and, in this case, to a door (wardrobe or door leaf) to a fixed structure or a jamb (wardrobe or door leaf).

Among the hinges, those of the so-called “retractable” type are also known where the hinges are invisible when the door is closed, on the one hand, and allow the door to rotate to approximately 180 °, on the other hand. In particular, they contain two bodies that are embedded in the thickness of the door and the jamb, and are connected to each other by a pair of levers, which, of course, allow the body to rotate relative to another body, and thus the door relative to the jamb. Each of the two levers is pivotally attached to the other in the zone enclosed between the two ends, and has one end pivotally attached to one of the two bodies of the loop, and the second sliding along the other body.

Among the retractable hinges, those of an adjustable type are known, where the hinges contain two ribbed containers, or “bowls,” which are embedded in the thickness of the door and the jamb, and which form a receiving casing for the respective hinge bodies that are connected to each other via a pair of articulated levers. Loop adjustment is usually possible due to the relative mobility of each loop body within the respective bowl.

However, traditional adjustable retractable hinges are not ideal, because to adjust the distance that the two hinge bodies must be able to face each other, that is, the distance between the door and the jamb when the door is closed, you need to work with two different adjustment screws that lift each body loops or forces them to either protrude from or slide into the corresponding bowl. It is easy to understand that such an operation is quite complicated, since it requires achieving a balance of action of two different adjustment screws.

Usually, traditional hinges have a rather limited range, and therefore the cavity of the bowl casing in the door is not centered relative to its thickness, but instead is slightly offset in the direction of its outer surface. Accordingly, the door can pivotally attach only on one side of the jamb, that is, either on the right side or on the left side, but cannot pivotally attach to any of them optionally.

Currently, however, there is a need for a door whose hinges are equally convenient to install on the right or left relative to the jamb, and to achieve this, the cavity should be centered relative to the thickness of the door, that is, in a position at an equal distance between two opposite edges that define the thickness the door. However, with this installation mode, traditional hinges having a rather limited angle of rotation do not allow the door to open a full 180 ° relative to the jamb.

JP 2007177427 describes a hinge in which two bodies that are received in the enclosing bowls are made up of two separate parts, and in particular, consist of an intermediate sliding member and a support member for the hinge hinges. A large number of components (at least six) makes this design of this loop rather complicated. In addition, to adjust the assembly formed by the specified intermediate element and the support element for the articulated levers in the direction of greater or lesser depth of immersion within the corresponding enclosing bowl, it is necessary to loosen the two engagement screws located on the opposite ends of the specified support element, and only after this operations can be operated with a central adjustment screw. This slows down and complicates the adjustment, because it is necessary to work with three different elements, that is, two engagement screws and a central adjustment screw, in turn.

The objective of the invention is to create an adjustable hinge with the possibility of installation in a cavity located in a central position relative to the thickness of the door, and which at the same time allows the door to open a full 180 ° relative to the doorframe.

Another objective of the present invention is to create an adjustable loop, which is more compact and smaller than similar traditional loops.

Another objective of the present invention is to create a loop with the ability to install and adjust relative to the jamb in all directions in a simple, easy, fast and accurate way.

Another objective of the present invention is to create a loop in which it will be sufficient to work with one element to adjust the direction of its greater or lesser depth.

Another objective of the present invention is to create an adjustable loop with fewer components.

Another objective of the present invention is to create a loop that is easier and faster to assemble.

Another objective of the present invention is to create an adjustable loop, which allows a greater range in comparison with traditional ones.

Another objective of the present invention is to create an adjustable loop, which will be much cheaper than similar traditional loops.

Another objective of the present invention is to create an adjustable hinge, which will have an aesthetically pleasing appearance after installation in a jamb and in a door.

Another objective of the present invention is to create an adjustable loop, which has an alternative characteristic - both structurally and functionally in comparison with traditional loops.

These tasks, individually or in any combination thereof, as well as others arising from the following description, are solved in accordance with the present invention with the help of an improved loop having the features according to paragraph 1 of the claims.

In addition, the present invention is described by means of some preferred embodiments, given as an example, not of a restrictive nature, with reference to the accompanying drawings, in which:

Figure 1 (Fig. 1) is a top perspective view of a loop in accordance with the present invention;

Figure 2 (Fig. 2) is a top view of a loop;

Figure 3 (Fig. 3) is an exploded perspective view of a loop; and

Figure 4 (Fig. 4) is a longitudinal section along IV-IV of figure 2;

Figure 5 (Fig. 5) is a longitudinal section along V-V of figure 2, and

Figure 6 (Fig. 6) is a transverse section along the IV-IV of figure 2.

As can be seen from the figures, the loop 2, in accordance with the present invention, contains two bodies 4, 6 of the loop, taken in two enclosing casing 8, 10, both having the shape of a bowl, respectively.

The second body 6 of the loop is made integrally, which is separated from the enclosing casing 10, within which the specified second body. Preferably, the first body 4 of the loop is also made integrally, separately from the enclosing casing 8, within which the specified first body.

Two enclosing enclosures 8, 10 are intended to be inserted into the first cutout of the casing and the second cutout of the casing (not shown), obtained in a jamb and in a door that must be hinged to the jamb, respectively.

It should be noted that hereinafter the “closed” state of the hinge means a state in which the door is closed and lies in the same plane as the jamb, and two hinge bodies 4, 6 inserted into the corresponding enclosing casings 8, 10 are facing each other.

The “open” state of the hinge, in this case, means the state in which the door is fully open and is in a different but parallel plane relative to the jamb, and two hinge bodies 4, 6 inserted into the corresponding enclosing casings 8, 10 are facing each other to a friend.

In addition, it should be noted that hereinafter, the length means the continuation of the body 4, 6 of the loop along the direction (X axis), parallel to the axis of the hinge of loop 2, the width means the continuation of the body of the loop along the direction (Y axis) perpendicular to the previous one and parallel to the thickness of the door or door frame , and the height / depth means the continuation of the hinge body along the direction of embedding (Z axis) of those of the door or jamb.

The two enclosing casings 8, 10 have an almost identical shape, which contains two flat end flanges 16, 16 ', mutually separated by an internal hollow section 18, 18' in the form of a parallelepiped.

Within the hollow portion 18 'of the enclosing casing 10, that is, the hollow portion of the enclosing casing intended to be inserted into the door, there is a guide means 20 for the corresponding body 6, intended for adoption in the specified casing 10.

In more detail, this guide means 20 comprises two protruding parallel tides 21 that emerge from the bottom 23 of the hollow portion 18 ′ at its ends.

These tides 21 work as guides for the corresponding elongated cavities 24 present in the other tides 25 of the body 6; in particular, the shape of the elongated cavities 24 and corresponding tides 21 is such as to facilitate the introduction of the body 6 into the enclosing casing 10, and also to allow sliding along the Z axis of the specified body 6 relative to the specified casing 10 during the adjustment step.

The body 6 has a raised central zone (section) 28, with an arrangement between two hollow zones 29. Preferably, this raised central zone 28 has an upper base 30 with a structure substantially complementing the outer surface of the central lever 52, as described below, which is closed the loop should rest on the indicated upper base 30 of the indicated raised central zone 28. This makes the loop compact enough also when closed.

In addition, in the raised central zone 28 of the body 6, with the purpose of restricting the door, there is an element for adjusting its movement along the Z axis, for selecting a greater or lesser depth of insertion into the corresponding enclosing casing 10.

In particular, this adjustment element contains a screw 41, located in a milled hole 32, located in the specified Central zone 28, parallel to the Z axis, which is not allowed to move along the axis within its casing of a pair of parallel pins 42 inserted into special holes 34 in the lateral surface of the body itself, parallel to the Y axis.

The depth adjustment (that is, along the Z axis) of the body 6 in the enclosing casing 10 is carried out by screwing the threaded portion of the screw 41 into the corresponding threaded hole 35 present in the bottom 23 of the enclosing casing itself.

Preferably, the same adjustment element 41, which allows you to adjust the depth of the body 6 within its enclosing casing 10, also ensures the fastening and pairing of the body 6 and its casing 10.

The connection between the two bodies 4 and 6 is obtained by means of three hook-shaped levers, of which one central 52 and two outer 54, 56.

In particular, the central lever 52:

- has a pair of cylindrical lateral tides 53 at the first end for swiveling with the body 6 by means of a pin 62; the length of each tide 53, excluding the part that engages with the body 4, is almost equal to the lateral extension (that is, along the X axis) of the central portion of each of the two outer arms 54, 56;

- slides at its other end along a pair of front guides 65, available in the body 4, with meshing using a pair of end tides 64, available in the lever itself;

- pivotally connected by its central portion to the external levers 54, 56 by a common pin 58. [F1]

Accordingly, two external levers 54 and 56:

- pivotally connected to the body 4 by a pin 66, which intersects the corresponding tides 55, with the exit to the side inward from each lever, and with a total length practically equal to the lateral extension (that is, along the X axis) of the central portion of the central lever 52;

- slide by means of tides 60, with a lateral exit from the second end, along a pair of front guides 67 located on the side walls that define the hollow zones 29 of the body 6;

- pivotally connected through the Central section to the Central lever 52 at the specified common pin 58.

When the door rotates relative to the jamb from the closing state to the opening state, the levers 52, 54, 56 of the hinge 2 rotate relative to the various hinge pins 62, 66, 58, while the corresponding tides 60 and 64 slide along the respective rails 67 and 65.

Preferably, the length of the raised central zone 28 of the body 6 (i.e., the extension along the X axis) is almost equal to the lateral extension of the central portion of the central lever 52 (i.e., without two lateral tides 53), while the length of each hollow zone 29 is almost equal to the lateral extension (i.e. along the axis X) of the corresponding central portion of the outer arm 54, 56.

Preferably, the guides 67 present in the body 6 of the tides 60 of the outer arms 54, 56 have a circuit with a first region 70, with a slope and open at the top. This is especially convenient because it facilitates the assembly of the loop, in particular by facilitating the insertion of levers 54, 56 from the upper base 30 of the body 6.

Preferably, the first region 70 is then extended along the second region 72, which is tilted in the opposite way with respect to the direction of extension of the first. In particular, the first region 70 and the second region 72 are a continuation of each other, and, in more detail, as shown in FIG. 6, the direction of continuation of the second region 72 forms an obtuse angle with the direction of continuation of the first region 70.

This configuration of the guides 67 is particularly convenient, since it is assumed that during the opening and closing step of the door 14, the door performs a sufficiently complicated movement to avoid the vertical edge of the jamb 12.

Preferably, the height of the body 6 to be received in the casing 10 to be applied to the door is greater than the height of the other body 4, while the width of the latter is preferably less than the casing 8 that receives it to limit adjustment movements along the Y direction within the casing itself.

In addition, on the side 16 'of the enclosing casing 10 there are first slots 42, which can be tightened with screws for stable fixation of the body itself in the corresponding cutout available in the jamb. These first slots 42 extend along the X direction and allow adjustment of the position of the casing 10 in the installation cavity made in the door, and thereby the adjustment of the door in this direction.

Almost round holes 43, which can be tightened with screws for stable fixation of the body itself in the corresponding cavity for installation made in the door, are on the side 16 of the enclosing casing 8, intended for insertion into the casing.

In the body 4 there are tides 45, where there are second tide slots 46 ', which can be tightened by screws 77 to stably fix the body itself in the corresponding enclosing casing 8. In addition, there is a cam 76 in the body 4, this cam can be accessed from the upper base of the body, and it interacts with the corresponding cavity 79, available in the bottom of the enclosing casing 8, and through its rotation, regulates the position of the specified body 4 relative to its casing 8 along the Y direction.

Basically, to adjust the loop 2 along the Y axis, first the fixing screws 77 are slightly loosened, and then the cam 76 is rotated by acting on its upper accessible end until the body 4 moves into its enclosing casing 8 along the Y axis, in the necessary degrees.

In addition, the third slots 48 are on the sides 16, 16 'and the enclosing casings 8, 10, and two bodies 4, 6, these slots can be activated by the corresponding tides available in the closing masks 50 of the cuts, for their locking interface.

In an embodiment not shown here, body 4, that is, a body intended to mate in a cavity provided in a jamb, may be integrally formed with its corresponding enclosing casing 8.

It is preferable, in this case, that there are no fixing screws 77, no cam 76, and, in addition, instead of round holes 43, there are slots in the Y direction, and which allow adjustment of the position of the body 4 made integrally with its corresponding casing 8, in the installation cavity in the jamb, thereby adjusting the loop along this direction.

In the embodiment shown and described previously, the body 6 should enter the cavity provided in the door, while the body 4 should enter the cavity provided in the jamb, however, it is understood that in an alternative embodiment not shown here, the body 6 may enter the cavity available in the jamb, while the body 4 can enter the cavity available in the door. In other words, in such an alternative embodiment, the configuration is substantially inverse to that described and shown previously.

From the foregoing, it is obvious that the retractable adjustable hinge in accordance with the present invention is more preferable than traditional retractable adjustable hinges because:

- a smaller loop;

- the loop has a larger range, with the same dimensions and materials;

- the loop consists of a reduced number of components, and therefore, it is simpler and easier to use, and thus it is cheaper;

- the loop allows you to easily and quickly adjust yourself, eliminating the risk of lateral vibrations, since the adjustment of the body in its enclosing casing is achieved by acting on one point, on the central screw, and this ensures accurate and uniform movement of the body along the side rails that are on equal distance from the central screw;

- it is simple and quick to assemble;

- it has a significant range of hinge connection, thereby providing a greater distance between the corresponding enclosing housings when they are in the configuration "one opposite the other" (that is, when the door is open and rotated 180 ° relative to the jamb); in particular, this allows you to drill the installation cavity for the hinge in the door in a position that is at an equal distance from the two front surfaces, thereby allowing articulation of the door itself on both the right side of the door and the left side of the door.

In particular, the retractable adjustable loop in accordance with the present invention has the following differences from JP 2007177427:

- the corresponding bodies, which are received in the corresponding enclosing bowls, are made in one piece, and, as an advantage, this greatly simplifies the manufacture and assembly of the loop itself;

- adjusting the depth of the body within its enclosing casing is carried out exclusively by acting on the adjustment screw located in the central portion of the body itself, without any need to further loosen the fixing screws, which are not there; this allows you to speed up and greatly simplify this adjustment operation;

- adjustment of the depth of the body in its enclosing casing is carried out by means of one adjustment element, which is also the only element for attaching the specified body to the specified casing.
