Abstract

In a mechanism for supporting and moving a door wing (1) with rotary and translating movement, the door wing (1) is engaged pivotally, around a first vertical axis of rotation (40) passing through the door wing (1), to translation means (5) which slide in a guide (2), and is pivotally restrained, around a third axis of rotation (80), to the second end (9b, 11b) of two arms (9, 11), the first end (9a, 11a) of which is pivotally engaged on the door frame to which the door wing (1) belongs on a second axis of rotation (60). The supporting mechanism comprises a first (16) and a second (16') snap-hooking device, each acting between the third means of rotation (8) and the second end (9b, 11b) of the first upper arm (9) and, respectively, of the second lower arm (11), and activated with a movement on a plane perpendicular to the third axis of rotation (80).

Description

FOR A CLOSURE ELEMENT WITH ROTARY AND TRANSLATIONAL MOTION

Technical field

The object of the present invention is a mechanism for supporting and moving a door wing, or a similar closure element, with rotary and translational motion.

Prior Art

Doors are known in which the door wing may be moved between the open position and the closed position with both a rotary and a translating motion. In supporting and moving mechanisms used for this aim, the door wing is pivotally restrained, around a first vertical axis of rotation passing through the door wing, to translation means (for example a carriage) which slide in a sliding guide. The door wing is also pivotally restrained, around a third axis of rotation, to the second end of two arms, the first end of which is, in turn, pivotally engaged on a second axis of rotation to the door frame to which the door wing belongs.

When a user pushes or pulls the door wing to open the door, the above- described mechanism determines a rotation around the first axis which immediately induces an opposite rotation of the arms around the third axis of rotation, in turn followed by a rotation, again opposite, of the arms around the second axis of rotation fastened to the door frame (in particular to a jamb). Simultaneously, the first axis translates along the sliding guide, thus accompanying and allowing the rotations of the arms around the second and third axis. This movement is inverted when the user acts to close the door again.

The movement the door is guaranteed by the mechanism of the supporting and moving mechanism structured in this manner allows reducing the volume of the space "covered" by the door wing during the opening and closing movement, with respect to the space covered by a common swing-door wing hinged directly to the doorpost of the door. In this manner, this type of door may be installed in rooms with reduced manoeuvring space and/or beside other doors where normal swing-doors would be an obstacle and interfere. Furthermore, doors equipped with the type of mechanism described above may also be installed in places where it would not be possible to install rigid sliding door wings.

Another advantage to doors with a door wing movable with both rotary and translational motion as described above is the one of being easy to adapt to an opening in both directions of the passageway. Furthermore, the distance between the user and the handle used to move the door decreases as the door wing. This makes this type of door particularly simple to use also by disabled persons or persons with reduced mobility.

A mechanism of this type for example, is illustrated in Patent Publication WO 2006 120742 Al.

The above-described mechanisms for supporting and moving a door wing, or a similar closure element, with rotary and translational motion have certain drawbacks.

In particular, the installation of a door wing provided with the supporting and moving mechanism, and/or the engagement of the door wing to the supporting and moving mechanism, may often turn out to be very complicated.

Description of the invention

The aim of the present invention is to obviate the above-described drawbacks by providing a mechanism for supporting and moving a door wing, or a similar closure element, with rotary and translational motion, which makes engaging the door wing to the mechanism itself easy and simple.

These and other aims again, which will be more apparent during the course of the description below, are achieved, in accordance with this invention, by a mechanism for supporting and moving a door wing, or a similar closure element, with rotary and translational motion having the structural and functional features in accordance with the appended independent claim, as further embodiments thereof are identified in the appended and corresponding dependent claims.

With reference to the drawings, the supporting and moving mechanism of a door wing, or of a similar closure element, with rotary and translational motion, comprises the following elements to be associated with a door wing 1 :

a sliding guide 2 to be associated with an upper cross member 3 of a door frame comprising the door wing 1 ;

first means of rotation 4 which form a first vertical axis of rotation 40 of the door wing 1 to be located in an intermediate position between two vertical edges 10a, 10b of the door wing 1 ;

translation means 5 positioned so as to slide in the sliding guide 2, the first means of rotation 4 pivotally restraining the door wing 1 to the translation means second means of rotation 6 which form a second axis of rotation 60 parallel to the first axis 40 to be located near a first jamb 7, or doorpost, of the door frame;

- third means of rotation 8 which form a third axis of rotation 80 parallel to the first and to the second axis 40, 60 and to be located on the door wing 1 in a position that, when the door wing 1 is in the closed position, is intermediate between the first and the second axis 40, 60;

two articulating arms 9, 1 1 , a first upper arm 9 and a second lower arm 1 1 , each pivotally restrained by means of its first end 9a, 1 1a to the second means of rotation 6 and, therefore, to the frame, and each pivotally restrained by means of its second end 9b, l ib to the third means of rotation 8 and, therefore, to the door wing 1.

The above-described structure is the one that gives the door wing 1 the characteristic combined rotation and translational motion (see in particular figures from 1 to 3).

In general, the translation means 5 comprise a sliding carriage 51. The door wing 1 is pivotally sustained by the carriage 51. Specifically, the carriage 51 comprises a support rod 51 1. First means of rotation 4 are provided at the support rod 511.

The supporting and moving mechanism according to the invention also comprises a device 12 for controlling the movement of the door wing 1 towards the closed position and the movement of the door wing 1 towards the open position. The control device 12 acts between the translation means 5 and the sliding guide 2 (or the upper cross member 3 to which the guide 2 is to be associated).

The device 12 for controlling the movement of the door wing 1 in turn comprises a device 13 for storing mechanical energy and an activating device 14, active on one another in a first final section and in a second final section of the motion of the translation means 5 along the sliding guide 2. The first final section of the motion of the translation means 5 along the sliding guide 2 is defined between a first final position, corresponding to the closed position of the door wing 1 (see figures 5 and 7), and a first engaged position located at a predetermined distance from the first final position. The second final section of the motion of the translation means 5 along the sliding guide 2 is defined between a second final position, corresponding to the open position of the door wing 1 (see figures 4 and 6), and a second engaged position located at a pre-determined distance from the second final position and intermediate between the second final position and the first engaged position. The storage device 13 and the activating device 14 are mutually disengaged between the first and the second engaged position. The storage device 13 transfers mechanical energy to the translation means 5 in the first and, respectively, in the second section (of the motion of the translation means 5 along the sliding guide 2) by means of the activating device 14 during the motion towards the first final position and, respectively, towards the second final position. The storage device 13 is instead charged by the activating device 14 in the first and, respectively, in the second section during the opposite motion towards the first engaged position and, respectively, towards the second engaged position. The storage device 13 remains in its charged state during the motion of the translation means 5 between the first and the second engaged position.

The device 12 for controlling the movement of the door wing 1 also comprises a device 15 for dampening the motion of the translation means 5 which is active on the translation means 5 to slow down their motion in the first section towards the first final position and in the second section towards the second final position.

Due to the control device 12, when the translation means 5 are either in the first or in the second section of their motion along the sliding guide 2, the door wing 1, when released by the user, is recalled respectively towards the closed position or towards the open position, but in a dampened and controlled manner, so as to avoid risks for the user and/or noisy contacts between the door wing 1 and the door jambs. Furthermore, when the user opens and/or closes the door, by moving the door wing 1 from the closed position towards the open position and/or vice versa, the storage device 13 is charged with mechanical energy which it then supplies during the inverse movement. In the passage of the translation means 5 between the first and the second engaged position, the door wing 1 is substantially free from stresses (which are not the ones exerted by the user).

The device 13 for storing mechanical energy comprises a first storage unit 130 equipped with a relative first slider 131 which is engaged with the activating device 14 in the first final section alone. The first slider 131 is movable on the first storage unit 130 parallel to the sliding guide 2 between a position of minimum charge of the first storage unit 130, which corresponds to the first final position of the translation means 5, and a position of maximum charge of the first storage unit 130, which corresponds to the first engaged position.

The device 13 for storing mechanical energy comprises a second storage unit 130' equipped with a relative second slider 13 Γ which is engaged with the activating device 14 in the second final section alone. The second slider 13 is movable on the second storage unit 130' parallel to the sliding guide 2 between a position of minimum charge of the second storage unit 130', which corresponds to the second final position of the translation means 5, and a position of maximum charge of the second storage unit 130', which corresponds to the second engaged position.

The device 13 for storing mechanical energy also comprises means 132, 132' for stabilizing the first and the second slider 131, 13 Γ in the position of maximum charge when the first and the second slider 131, 13 are disengaged from the activating device 14.

The damper device 15 comprises:

a first damper unit 150, engaged on the first slider 131 and acting to slow down the movement of the translation means 5 towards the first final position; - a second damper unit 150', engaged on the second slider 13 and acting to slow down the movement of the translation means 5 towards the second final position.

Advantageously, the first damper unit 150 is integrated within the first storage unit 130, as the second damper unit 150' is integrated within the second storage unit 130'.

By way of non-limiting example, the first and the second storage unit 130,

130' may be made, as illustrated in particular in figure 9 which, although it refers to a specific embodiment of the invention, illustrates an example of a storage unit common to all embodiments. Specifically, the slider 131, 13 of each storage unit 130, 130' moves guided in the storage unit 130, 130' along a respective guide groove 134, 134'. The means 132, 132' for stabilizing the position of the slider 131, 13 in the position of maximum charge when the slider 131, 13 is disengaged from the activating device 14 comprise a twisted portion 135, 135' of the guide groove 134, 134' to which the slider 131, 13 is dragged by the activating device 14, thus remaining imprisoned by it until a new interaction with the activating device 14. The slider 131, 131 ' is pivotally engaged at one end of a rod 151, 151 ' of a piston and cylinder damper which is part of the damper unit 150, 150' acting on the slider 131, 131 '. The cylinder 152, 152' of the damper is fastened to a casing 136, 136' of the storage unit 130, 130'. The slider 131, 13 Γ is subjected to elastic return means 137, 137' (for example a helical spring with linear extension, as schematically indicated in figure 9, in the added detail of an element inside the storage unit 130, 130'). However, any other equivalent element which stores the mechanical energy of the storage unit 130, 130' could be used.

The slider 130, 130' has a seat 133, 133' for engaging an interfering element 140, 140a, 140b to interfere with the activating device 14.

Opportunely, the sliding carriage 51 is equipped with a hooking end 52 which will be discussed in detail below.

In one embodiment of the invention, illustrated in particular in figures 4 and 5, the first storage unit 130 is fastened to the sliding guide 2 (or to the relative upper cross member 3) at the first final position, while the second storage unit 130' is fastened to the sliding guide 2 or to the relative upper cross member 3 at the second final position. The activating device 14 comprises an interfering element 140 which is integral with the translation means 5 and intended to be engaged, each time, as a function of the position of the translation means 5 on the sliding guide 2, in the seat 133 of the first slider 132 and in the seat 133' of the second slider 132'.

Advantageously, the interfering element 140 is integral with the sliding carriage 51. In addition to the hooking end 52, the sliding carriage 51 is also equipped with a fist support 53 fastened to the hooking end 52 and intended to support the element 140 for interfering with the activating device 14. In the specific embodiment illustrated in figure 8, the interfering element 140 comprises a prong 141 that projects from a base 142, which can be fastened (for example by means of through screws 143 and relative nuts 144) to a flanged portion 530 of the first support 53. Advantageously, the first support 53 is removably fastened to the hooking end 52 of the sliding carriage 51 (in particular by means of respective through screws 531 and nuts 532).

The embodiment now described (and illustrated, in particular, in figures 1 , 2, 4, 5, 8, 12, 13 and 14) is preferably (although not exclusively) employed in doors in which the frame is made of metal section bars (preferably steel or aluminium) which are coupled to and/or are incorporated within a masonry wall or a panelled wall made of various materials, in particular plasterboard.

In one embodiment of the invention, illustrated in particular in figures 6 and 7, the first storage unit 130 and the second storage unit 130' are both fastened, side by side, to the translation means 5. The travels of the relative first and second slider 131, 131 ' extend parallel to the sliding guide 2 in opposite directions starting from a same area 50 of the translation means 5. The positions of minimum charge of the first and of the second slider 131, 13 are proximal to each other and the positions of maximum charge of the first and of the second slider 131, 13 Γ are distal to each other. The activating device 14 comprises a first interfering element 140a which is fastened to the sliding guide 2 (or to the relative upper cross member 3) in a position which corresponds to the position of minimum charge of the first slider 131 when the translation means 5 are in the first final position. The first interfering element 140a remains engaged in the seat 133 of the first slider 131 along the entire first final section of the motion of the translation means 5 and remains disengaged from the seat 133 of the first slider 131 in the remaining part of this motion. The activating device 14 comprises a second interfering element 140b which is fastened to the sliding guide 2 (or to the relative upper cross member 3) in a position which corresponds to the position of minimum charge of the second slider 13 when the translation means 5 are in the second final position. The second interfering element 140b remains engaged in the seat 133' of the second slider 13 along the entire second final section of the motion of the translation means 5 and remains disengaged from the seat 133' of the second slider 13 in the remaining part of this motion. As illustrated in particular in figure 9, in addition to the hooking end 52, the sliding carriage 51 is also equipped with a second support 53' which is fastened to the hooking end 52 and intended to support, on two of its sides 53 'a, 53'b, the first and the second storage unit 130, 130'. Advantageously, the second support 53' is removably fastened to the hooking end 52 of the sliding carriage 51 (in particular by means of respective through screws 53 and nuts 532').

The embodiment now described (and illustrated in particular in figures 3, 6, 7, 9, 16a and 16b) may be preferably (but not exclusively) employed in doors with a wooden frame.

Advantageously, the hooking end 52 of the sliding carriage 51 is intended to indifferently support the first or the second support 53, 53'. In this manner, it is possible to use the same sliding carriage 51 for both embodiments.

Opportunely, the damper device 15 comprises an auxiliary damper unit

150", which is fastened to the sliding guide 2 (or to the upper cross member 3 to which the guide 2 is to be associated), at the first final position of the translation means 5 and acting on them for at least a terminal part of the first final section of the motion of the translation means 5. Specifically, the auxiliary damper unit 150" comprises a piston and cylinder damper, the piston of which acts on a stop element 533, 533' obtained on the translation means 5. In particular, the stop element 533, 533' is obtained on the sliding carriage 51, preferably on the first support 53 or on the second support 53'.

To facilitate the hooking of the door wing 1 to the supporting and moving mechanism, the mechanism itself comprises a first 16 and a second 16' snap- hooking device, each acting between the third means of rotation 8 and the second end 9b, l ib of the first upper arm 9 and, respectively, of the second lower arm 11, and each activated with a movement, respectively, of the second end 9b, l ib of the first upper arm 9 and, respectively, of the second lower arm 11, relatively to the door wing 1, on a plane perpendicular to the third axis of rotation 80.

In this manner, once the door wing 1 is hooked to the sliding guide 2 in a usual manner (by inserting the translation means 5 into it, in particular the sliding carriage 51, for example by means of a enlarged inlet in the sliding guide 2) it is possible to hook the door wing 1 permanently with a simple rotary movement of the first upper arm 9 and of the second lower arm 1 1 around the second axis of rotation 60, without requiring other types of complex operations.

The specificities and features are described below of the first and of the second snap-hooking device 16, 16', with particular reference to figures 10a - 10c, 1 1a, l ib (and also 14 which, although it refers to a variant of the mechanism of the invention, is generally valid for the description of the hooking device). Although they illustrate principally the first hooking device 16, these figures are also directly applicable to the second hooking device (as made apparent by the indication of the numeric references relative to both the hooking devices).

Specifically, advantageously the first snap-hooking device 16 comprises a first pin 81 , protruding from an upper edge 10c of the door wing 1 with an axis parallel to the third axis of rotation 80, and a first seat 90 of the first pin 81, obtained on the second end 9b of the first upper arm 9. The first seat 90 is equipped with a first inlet 91 in which the first pin 81 can be inserted with a movement perpendicular to the third axis of rotation 80. Placed in this first inlet 91 is at least one first elastically deformable element 92 which snap inserts and locks the first pin 81 in the first seat 90. Furthermore, the second snap-hooking device 16' comprises a second pin 81 ', protruding from a lower edge lOd of the door wing 1 with an axis parallel to the third axis of rotation 80, and a second seat 90' of the second pin 8 , obtained on the second end l ib of the second lower arm 11. The second seat 90' is equipped with a second inlet 91 ' in which the second pin 81 ' can be inserted with a movement perpendicular to the third axis of rotation 80. Placed in this second inlet 91 ' is at least one second elastically deformable element 92' which snap inserts and locks the second pin 8Γ in the second seat 90'. The third means of rotation 8 comprise the first pin 81, the first seat 90, the second pin 81 ' and the second seat 90' .

As illustrated in particular in the figures (11a, l ib), the first and the second elastically deformable element 92, 92' each comprise a respective tongue 93, 93' which is fastened respectively to the first and to the second inlet 91, 91 ' of the first and, respectively, of the second seat 90, 90'. This respective tongue 93, 93' is free to rotate in a direction transversal to the inlet direction of the respective first or second pin 81, 81 ' against the action of a respective elastic means 94, 94' (elastic means which may, for example, be made by means of the stem for connecting the tongue 93, 93' to the first or to the second inlet 91, 9 ). The first or second pin 81, 81 ' is locked in the respective first or second seat 90, 90' by a free end 95, 95' of the tongue 93, 93', due to the elastic return of the tongue after the passage of the pin.

Preferably:

the first seat 90 and the first elastically deformable element 92 are obtained on a first insert 96 accommodated in a respective first housing 97 on the second end 9b of the first upper arm 9;

the second seat 90' and the second elastically deformable element 92' are obtained on a second insert 96' accommodated in a respective second housing 97' on the second end 1 lb of the second lower arm 1 1.

The first and the second insert 96, 96' may also be made of plastic material, by moulding. Advantageously, by acting with a tool on the first and on the second deformable element 92, 92' (which are easily exposed and made accessible by rotating the door wing 1 as, for example, in figures 2 and 3), it is possible to free the first and the second pin 81, 81 ' and to release the door wing 1 again from the first upper arm 9 and from the second lower arm 11. In this manner, maintenance or adjustments are made easy.

As illustrated in the figures, the first and the second seat 90, 90' are shaped like through slots, which are open on the insertion side of the respective pin 81, 8 . The pin 81, 8 may be made with a cylindrical element equipped with an enlarged pull-resistant end 811, 811 ' for movements along the third axis of rotation 80.

The first inlet 91 of the first seat 90 for housing the first pin 81 and the second inlet 91 ' of the second seat 90' for housing the second pin 81 ' are placed, respectively, on a side edge 98 of the first upper arm 9 and on a side edge 1 10 of the second lower arm 11.

In a first embodiment illustrated in particular in figures 10a- 10c and 1 la, the direction for inserting the first pin 81 and the second pin 81 ' respectively into the first and into the second seat 90, 90' is transversal, preferably perpendicular, to a longitudinal axis of extension 99, 111 respectively of the first upper arm 9 and of the second lower arm 11.

In a second embodiment illustrated in particular in figure 1 lb, the direction for inserting the first pin 81 and the second pin 8 Γ respectively into the first and into the second seat 90, 90' is parallel to, preferably coinciding with, the longitudinal axis of extension 99, 11 1 respectively of the first upper arm 9 and of the second lower arm 11.

As illustrated in the figures, preferably the first upper arm 9 and the second lower arm 11 are simple or shaped planar elements; the lying plane of the second end 9b, l ib is perpendicular to the third axis of rotation 80 when the second end 9b, l ib is restrained to the third means of rotation 8.

Opportunely, the supporting and moving mechanism according to the invention comprises means for adjusting the relative distance between the second 6 and the third 8 axis of rotation.

In this manner, it is possible to adjust the position of the door wing 1 also when there are small assembly imperfections in the frame.

In the embodiment illustrated in figures l ib and 1 1c, the first insert 96 and/or the second insert 96' is movable in the respective first and/or second housing 97, 97' at least along a respective direction D, D' parallel to a longitudinal axis of extension of the respective first upper arm 9 and/or of the second lower arm 11. The supporting and moving mechanism comprises means 17, 17' for adjusting the relative position of the first insert 96 and/or of the second insert 96' with respect to the respective first and/or second housing 97, 97' along the direction D, D'. As illustrated by way of example in figure l ib, the means 17, 17' for adjusting the relative position of the first insert 96 and/or of the second insert 96' with respect to the respective first and/or second housing 97, 97' along said direction D, D' comprise slots 170, 170' elongated in said direction D, D' for the passage of screws 171, 17 for fastening the first and/or the second insert 96, 96' to the respective second end 9b, 1 lb of the first and/or second arm 9, 1 1. The elongated slots 170, 170' are illustrated on the insert 96, 96', but they could similarly be obtained on the second end 9b, l ib of the respective arm 9, 1 1.

Advantageously, the means 17, 17' for adjusting the relative position of the first insert 96 and/or of the second insert 96' with respect to the respective first and/or second housing 97, 97' along the direction D, D' comprise at least one actuator 172, 172' for controlling the adjustment, which is active between the first and/or second insert 96, 96' and the respective first and/or second housing 97, 97'. This solution is illustrated in figure 1 1c where, by pure way of example, an actuator 172, 172' is illustrated in the form of an eccentric accommodated in a seat obtained on the second end 9b, l ib of the respective arm 9, 11, acting on the insert 96, 96' and accessible from the upper side of the respective arm 9, 1 1 (for example by bringing the door wing 1 to the position in figure 2 or 3).

In an alternative embodiment not illustrated in the figures, the insert 96, 96' is inserted in a separate support element, accommodated on the second end 9b, l ib of the relative arm 9, 11 and made integral with the arm 9, 11 with relative fastening means. The housing 97, 97' is obtained on the support element. The guides for sliding the insert 96, 96' in the direction of adjustment D, D' are obtained in it. The elongated slots 170, 170' may be indifferently made either on the insert 96, 96' or on the support element. The control actuator 172, 172' acts between the insert 96, 96' and the support element, in a way similar to that already described for the action between the insert 96, 96' and the housing 97, 97'.

In the embodiment illustrated in figures 14 and 14a, for example, in conjunction with or alternatively to the above illustration, the first pin 81 or the second pin 81 ' is movable with respect to the door wing 1 along the respective upper edge 10c or lower edge lOd of the door wing 1. The supporting and moving mechanism comprises the means 18, 18' for adjusting the position of the first pin 81 or the second pin 81 ' with respect to the door wing 1 along the respective upper edge 10c or lower edge 1 Od of the door wing 1. As illustrated by way of example in figures 14, 14a, opportunely:

the first pin 81 is integral with its own first base 810 which is fastened to the upper edge, 10c of the door wing 1 ;

- alternatively or in conjunction, the second pin 81 ' is integral with its own second base 810' which is fastened to the lower edge lOd of the door wing 1.

The means 18, 18' for adjusting the position of the first pin 81 or second pin 81 ' with respect to the door wing 1 comprise screws 181, 18Γ for fastening the first or the second base 810, 810' to the upper edge 10c or to the lower edge lOd of the door wing 1 which are inserted in respective slots 180, 180' elongated in the direction of adjustment.

Advantageously, the means 18, 18' for adjusting the relative position of the first base 810 and/or of the second base 810' respectively along the upper edge 10c and/or along the lower edge lOd of the door wing 1 comprise at least one actuator 182, 182' for controlling said adjustment, which is active between the first or the second base 810, 810' and the respective upper edge 10c or lower edge lOd of the door wing 1.

This embodiment is illustrated in figure 14a where, by pure way of example, an actuator 182, 182' is illustrated in the form of an eccentric acting between one support 812, 812', accommodated on the upper edge, respectively, lower edge 10c, lOd of the door wing 1, and the base 810, 810'. The base 810, 810' is accommodated in turn, movable in a guide, in a seat obtained in the support 812, 812'. The eccentric acts on the base 810, 810' and is accessible by bringing the door wing 1 to an at least partly open condition.

The supporting and moving mechanism according to the invention comprises a first 19, a second 20 and a third 21 tubular profiled element forming, respectively, the first jamb 7, the upper cross member 3 and a second jamb 7' of the door frame comprising the door wing 1. The first, second and third tubular profiled element 19, 20, 21 all have respective cross sections perpendicular to their own longitudinal axis of extension which are the same as a common cross- section model 22 (illustrated in particular in figure 15a).

The common cross-section model 22 provides: a first side 220a intended to face towards the space in which the door wing 1 is accommodated when it is in closed position, a second side 220b opposite to the first, and a third and a fourth side 220c, 220d which are transversal to the first two. The common cross-section model 22 also provides a first space 221 structured for the passage of the carriage 51 of the translation means 5 with its resting wheels 510 on a first and a second portion 221a, 221b of the first side 220a, which are separated from each other by a third intermediate portion 221c of the first side 220a. The third portion 221c can be eliminated for the passage of the rod 511 of the support carriage 51 for the door wing 1.

The common cross-section model 22 also provides seats 223 for inserting connecting screws between profiled elements. Preferably, the insertion seats 223 are obtained in a second space 222 of the common cross-section model 22.

The second tubular profiled element 20 has the third intermediate portion 221c of the first side 220a eliminated for the passage of the carriage 51 and provides the sliding guide 2.

In this manner, it is possible to make the entire door frame with a single type of section bar, thus simplifying the production of the components.

Opportunely, plates 224 for elements 512 for stabilizing the carriage 51 are obtained on the two sides of the first space 221 which are transversal to the first side 220a and face each other. The elements 512 for stabilizing the carriage 51 comprise a transversal stabilizing wheel 513. These elements are exploited in the second tubular profiled element 20, where the carriage 51 runs.

Obtained on portions of the walls of the first space 221 that are distal from the first side 220a are seats 225 for hooking elements functional to the supporting and moving mechanism, in particular directly or indirectly active on the translation means 5. In an embodiment illustrated in the figures, the hooking seats 225 are exploited for the first and the second storage unit 130, 130' of the device 12 for controlling the movement of the door wing 1 (as illustrated, for example, in figure 13).

Advantageously, obtained on the third eliminatable intermediate portion 221c of the common cross-section model 22 is a projection 226 which projects towards the inside of the first space 221, starting from a first stem part 226a, with a second enlarged part 226b, to define a substantially "T" shape, intended to hook counter-plates and/or bodies of door locks and/or similar elements which are functional when the common cross-section model 22 is incorporated within the jambs 7, T of the frame.

In the second tubular profiled element 20, this projection 226 is removed by the elimination of the third portion 221 c.

Figure 15d illustrates an example of use of the projection 226 for hooking a door lock counter-plate, in the second jamb 7'.

These results are obtained with a section like the one illustrated in 15b. It illustrates the section of the third tubular profiled element 21, coinciding with the cross-section model 22 from which a section of the third portion 221c was completely removed along the longitudinal axis of the profiled element 21 and, at the ends of this section, a portion alone of the most outer wall of the section itself, so as to expose a portion of the projection 226 overhangingly along the longitudinal axis of the profiled element 21. In production, these results are easily obtained with a first milling process which completely removes a longitudinal section of the third portion 221c, followed by a second more superficial milling process which only removes the outer wall 229 of the common cross-section model 22.

The first side 220a of the common cross-section model 22 comprises two side extensions 227a, 227b which protrude from opposite parts of the main body of the common cross-section model 22 to each form a respective edge 228a, 228b.

Advantageously, the two side extensions 227a, 227b form two reference and/or stop elements for an outer finishing and/or for a curtain wall, the respective edges 228a, 228b being shaped and positioned defilade in the space for housing the door wing 1 in the closed condition and to make the jambs 7, 7' and cross member 3 only visible in the thickness of a wall, in which the door is installed and the superficial finishing of the wall faces, which are plastered or of another type, extends until it outlines and delimits the space.

In this manner, a particularly pleasant appearance is obtained in terms of modern minimalist indoor architecture: the so-called "flush- wall" effect, in which the door becomes an element integrated within the wall, where every solution for continuity tends to be hidden from sight. Figure 15e illustrates an example for the application in a panelled wall, for example with plasterboard. Figure 15f illustrates an example for the application in a masonry wall.

Advantageously, the supporting and moving mechanism comprises a first angular connecting element 23 a between the first tubular profiled element 19 and the second tubular profiled element 20, having a first stop face 230a for a first end 20a of the second tubular profiled element 20 and a second stop face 231a, which is orthogonal to the first, for a first end 19a of the first tubular profiled element 19. This second face 231a of the first angular element 23a faces a longitudinal section of the second tubular profiled element 20, at a pre-determined distance from the tubular profiled element 20 such as to allow the accommodation and movement of the first upper arm 9.

The supporting and moving mechanism also comprises a second angular connecting element 23b between the second tubular profiled element 20 and the third tubular profiled element 21, having a first stop face 230b for a second end 20b of the second tubular profiled element 20 and a second stop face 231b, which is orthogonal to the first, for a first end 21a of the third tubular profiled element 21.

Advantageously, the first and the second face 230a, 23 la of the first angular element 23a have, on their side edges, a shape joining the edges 228a, 228b of the first tubular profiled element 19 with the respective edges 228a, 228b of the second tubular element 20 around the seat for housing the first upper arm 9. With this embodiment (illustrated in particular in detail in figure 1), the concealment of the frame elements is even more pronounced, with an even more pleasing appearance.

Advantageously, the supporting and moving mechanism comprises a resting element 23c, which can be associated with a second end 19b of the first tubular profiled element 19 opposite to the first and defining a pre-determined distance between the lower edge lOd of the door wing 1 and the level of the floor such as to allow the accommodation and the free movement of the second lower arm 11.

Opportunely, the second means of rotation 6 comprise a tubular bar 61 inserted in the first space 221 of the cross section of the first tubular profiled element 19 to form the second axis of rotation 60. The first upper arm 9 and the second lower arm 11 are restrained respectively to a first 61a and to a second 61b end of the tubular bar 61. The second means of rotation 60 comprise a first plug 62a which is integral with the first end 9a of the first upper arm 9. This first plug 62a is inserted in the first end 61a of the tubular bar 61 and is made integral with it. The second means of rotation 60 comprise a second plug 62b which is integral with the first end 11a of the second lower arm 11. This second plug 62b is inserted in the second end 61a of the tubular bar 61 and is made integral with it.

The rigid assembly formed by the arms 9, 11, by the plugs 62a, 62b and by the tubular bar 61 is kept in position along the longitudinal axis of extension of the first tubular profiled element 19 by two end bushings 63a, 63b. The two end bushings 63a, 63b each surround a respective end 61a, 61b of the tubular bar 61 , or a respective plug 62a, 62b or both. The two end bushings 63a, 63b each provide a rotating restraint, to the first tubular profiled element 19, of a respective end 61a, 61b of the tubular bar 61, or of a respective plug 62a, 62b or of both. The two end bushings 63 a, 63b are each inserted in one of the ends 19a, 19b of the first tubular profiled element 19.

The structure thus obtained is quite compact and is self-supporting inside the first tubular profiled element 19.

The invention has significant advantages. The device for controlling movement allows for a safe system involving a low risk of injury for the user. Easy assembly is possible with the structure of the quick-hooking system, of the door wing which, when needed (for maintenance or adjustments) may be quickly released from the arms without removing it entirely from the door opening. Due to the common structure of the section of the section bars forming the frame, it is possible to obtain jambs, cross members and sliding guides from a single extruded, custom-cut section bar. A few specific processing steps then allow specific components of the frame to be made. A concealed configuration is also achieved, of the minimalist ("flush- wall") type, of the frame and its components.

The invention thus conceived is susceptible to several modifications and variants all falling within the scope of the inventive concept characterizing it. Furthermore, all the details may be replaced by other technically equivalent elements. In practice, any materials and dimensions may be employed, according to needs.
