Description

DOOR AND DEVICE FOR IMPLEMENTING THE DOOR

The present invention relates to the field of doors. It is a door application in the field of building, but the invention is in fact applicable to any type of door, regardless of its application.

It relates more particularly to a door having at least one frame and at least one leaf, said leaf having a substantially rectangular shape oriented substantially vertically and being delimited at its lateral ends by vertical edges and at its upper and lower ends by horizontal edges, the leaf being movable relative to the frame between two positions: a closed position in which it closes a vertical opening made in the frame and an open position in which it is positioned substantially perpendicular to the opening. It is known from European Patent Application No. ⁰ EP 1138861, a double door comprising a frame and two leaves, each leaf having a substantially rectangular shape defined by vertical and horizontal edges and being movable relative to the frame between two positions: a closed position in which it closes a vertical opening made in the frame and an open position in which it is positioned substantially perpendicular to the opening.

The movement applied to each wing is of a particular type:

In the closed position, a proximal vertical edge of the leaf is located near a vertical post of the frame and in the open position, this proximal vertical edge is away from this vertical amount of the frame and is the other vertical edge of the frame. flapping, the distal vertical edge, which is close to the vertical jamb of the frame.

The movement applied to the wing is thus formed on the one hand of a rotation on itself along a vertical axis situated at about one third of the width of the wing in the direction of said vertical pillar and on the other hand of a rotation of the support of this vertical axis relative to the vertical amount of the frame. The main consequence of this double rotation is that the vertical edges of the wing are themselves also rotated relative to this vertical axis along two horizontal arcs of circles.

A major disadvantage of the device presented in this document consists in the fact that the two vertical end edges of the leaf "overflow" during the closing movement of the leaf in the sense that, for the distal vertical edge of the beating, the latter out of the closing plane of the door, that is to say the middle plane of the leaf in the closed position and for the proximal vertical edge of the wing, the latter out of the middle plane of the leaf in the open position.

To operate the double rotation, a horizontal rod is mounted between the frame and the flap at least in the upper part and preferably in the upper part and in the lower part of the door. It is rotatable relative to two vertical axes, one associated with the vertical upright and the other associated with the wing and positioned at about one third of its width, towards the vertical upright.

However, there is a problem of reliability in guiding this double rotational movement because the fact that the axis associated with the leaf is shifted towards a vertical edge, the proximal edge of the leaf, the application of a force near the other vertical edge, the distal edge of the leaf, generates a moment of force likely in the long run to cause a game at the rotating guide means.

In addition, the presence of the connecting rod at the bottom of the door requires a large recess to accommodate the pivot and the low link and / or forces to raise the leaf relative to the ground in such a way that the seal to the winds can no longer be ensured easily.

It is further known from European Patent Application EP ⁰ 1,754,852, a similar double leaf door with each leaf is animated by a movement of a hand rotating about a vertical axis and secondly to advanced non-rectilinear support of this axis through a curved guidance system located in the upper part of the frame of the door.

An important advantage of this device compared to the previous one is that each leaf does not protrude laterally during opening, beyond the lateral limit of the frame.

Furthermore, for reasons of reliability, it is preferable to also provide a rack system at the bottom, but then this system is in the passage of the door opening and greatly hinders.

The prior art also knows of the British Patent Application No. ⁰ GB 1560713 shower cubicle opening beating which is guided at its four corners by four horizontal guides, perpendicular in pairs, as well as possibly by an arm rotation along an axis passing through the middle of the wing. Such guidance is reliable, but is not applicable when it is desired that the passage through the opening of the door is clear of any guide element, particularly in the lower part.

In addition, when the opening is not actuated (pushed or pulled) in an exactly horizontal movement, but by exerting a force directed upwards or downwards, the elements of the opening which cooperate with the guides will come butter respectively upwards or downwards in the guides, these elements will then no longer be aligned two by two vertically and under the effect of force the door will get stuck.

This effect becomes more and more frequent as the door is used because the elements at the bottom of the opening that cooperate with the low guide also have the role of transmitting the weight of the door. game is inevitably formed and the door gets stuck more and more often.

The object of the invention is to overcome the drawbacks of the prior art by providing a door whose leaf is driven by a rotational / translational movement to move from the open position to the closed position and vice versa, but whose movement operates in a small space and in a reliable manner, without impeding the passage through the opening, particularly in the lower part of the door, and which is simple to manufacture and inexpensive.

The absence of any guiding element in the lower part of the opening is important to allow the passage of people with reduced mobility, having difficulty walking and a fortiori to allow the passage of people moving in a wheelchair.

The present invention thus relates in its broadest sense to a door according to claim 1. The dependent claims have particular characteristics of the door according to the invention.

The door according to the invention comprises at least one frame and at least one leaf, said leaf having a substantially rectangular shape oriented substantially vertically and being delimited at its lateral ends by vertical edges and at its upper and lower ends by horizontal edges, the leaf being movable relative to the frame between two positions: a closed position in which it closes a vertical opening made in the frame and an open position in which it is positioned substantially perpendicular to the opening, said leaf being animated on the one hand of a double rotation movement both on itself and by relative to the frame on a vertical axis, preferably substantially central and secondly a substantially rectilinear sliding movement of at least one vertical edge in a horizontal direction by means of sliding.

Thus, thanks to the rectilinear sliding along the horizontal of the vertical edge, and the rotation of the leaf on itself and with respect to the frame, we obtain a movement of passage from the open position to the closed position or conversely which is compact, because it is done in a very restricted space, without "overflowing" beyond the means allowing the sliding.

In a particular embodiment of the invention, the bottom rail of the guide system Sl is fixed directly to the ground. It can even be integrated into the ground so that the movements of the bottom carriage operate at least partially or completely below ground level.

According to the invention, the distance d between the vertical axis of the double rotation and the amount of the frame relative to which is considered the second rotation of the wing is preferably such that: d = px 1, with 1 the width of the beating and p a number greater than 0 and less than or equal to 0.5 or p a number greater than 0 and less than 0.5.

Thus, if the vertical axis is exactly central, that is to say at exactly the distance of the two vertical edges of the leaf, the vertical edge which does not cooperate with sliding means will also undergo a rectilinear sliding movement. However, for a more reliable support of the movement, it is preferable to also provide sliding means for the other vertical edge of the leaf in another horizontal direction.

According to the invention, a proximal vertical edge of the opening leaf is guided by a guiding system in a direction substantially perpendicular to the plane of the opening, said guiding system comprising at least two rails, one at the top and the left. the other at the bottom of the door, at least one top carriage and at least one bottom carriage being fixed to said proximal vertical edge and sliding each respectively relative to each of the up and down rails.

On the other hand, according to the invention, the sliding of said at least two carriages of two different rails is synchronized using a synchronization / connection system, preferably fixed to the frame, to vertically align said carriages up and down. and to allow them to slide in the same way at the same time.

Thus, because this high carriage and this bottom carriage are at least mechanically linked by the connecting system to move together, they present at any time, regardless of the opening angle of the opening relative to the frame, the same position according to the vertical, while of course being offset along this vertical since the high carriage is at the top of this vertical and the bottom cart is at the bottom of this vertical. Therefore, even if the opening is not actuated (pushed or pulled) in an exactly horizontal movement, during opening or closing, the sliding of the carriages itself will be exactly in a horizontal direction. Thus, it is no longer possible for a truck to butte or get stuck on the rail on which it slides.

If we choose an easy sliding of the carriages on their respective rails, the handling of the door is then easy and its movement can be easily motorized; there is no need for powerful motorization means.

Of course, it is possible for several top carriages to be fixed to the sash and / or several lower carriages to be fixed to the sash and at least a portion, and preferably all carriages, to be connected to the connecting system ensuring the synchronization.

It is also possible to provide a third horizontal rail, an intermediate rail located between the high rail and the low rail on which slides at least one intermediate carriage which is also attached to said proximal vertical edge of the leaf.

By "carriage" under the present invention should be understood to any means gliding or rolling on, against or inside a rail oriented substantially horizontally ei having a vertical sectional shape jde ^'qiune to enable this bearing or this deposit.

Moreover, it is quite possible to realize the door without particular means to guide the double rotation of the wing; However, for a more reliable accompaniment of the movement, it is preferable to provide special means to guide the double rotation.

Thus, according to the invention, it is possible to provide: only means for sliding the proximal vertical edge of the leaf which are offset perpendicular to the opening, but it is in fact preferable to provide: means for sliding the two vertical edges of the leaf, both lintel and perpendicularly offset or means for sliding the proximal vertical edge of the leaf and means for the double rotation of the leaf, and even it is still preferable to provide: means for sliding the two vertical edges of the leaf, the proximal vertical edge and the distal vertical edge, and means for the double rotation of the wing. However, when means are provided for the double rotation of the wing, they accompany the movement but do not transmit the bulk of the weight of the wing: it is the rails of the guide system that support essentially the weight of the wing.

In the context of the invention, the double rotation of the wing consists of a first rotation of the wing on itself of about 180 ° along its vertical axis, preferably central positioned at equal distance from the proximal vertical edge and the distal vertical edge. , and in a second rotation of the support of this central axis of about 90 ° relative to the frame which operates simultaneously with the first rotation.

In a preferred variant of the invention, the two vertical edges of the leaf are animated by a rectilinear sliding movement, by means of sliding means, in two horizontal, substantially perpendicular directions.

In this variant, the horizontal sliding directions of the vertical edges of the leaf are preferably oriented at an angle of between 80 and 100 °. The proximal vertical edge of the wing is guided by a guiding system, described as "deported" in a direction substantially perpendicular to the plane of the opening.

A distal vertical edge of the leaf can be guided by a guide system in a direction substantially in the plane of the opening. However, in this variant, the sliding means of the distal vertical edge are preferably only in the upper part of the door, in lintel above the opening and not in the lower part of the opening.

This guide system of the distal vertical edge of the wing thus preferably comprises a single rail in the upper part of the frame of the door, at least one carriage fixed to said distal vertical edge sliding relative to this rail.

It is also possible that the carriage sliding on the lintel rail is also synchronized using the synchronization / connection system fixed to the frame.

In a particular variant, the door according to the invention has no means for achieving the double rotation of the wing. However, in another variant, the double rotation is operated by rotation guiding means comprising an upper and / or lower link positioned respectively in the upper part and / or in the lower part of the door, a distal end of the connecting rod cooperating with a shaft mounted on the leaf and oriented along the vertical axis and a proximal end of the connecting rod cooperating with a base mounted on the frame and oriented vertically.

In this variant, preferably, in a first case the shaft is positioned equidistant from the proximal vertical edge of the wing and the distal vertical edge of the wing or in a second case the shaft is positioned closer to the proximal vertical edge of the wing than the distal vertical edge of the wing.

The length of the connecting rod or connecting rods is thus substantially equal to half the width of the leaf measured between the vertical edges in the first case where the length of the connecting rod or connecting rods is thus less than half the width of the measured leaf. between the vertical edges in the second case. The length of the connecting rod or rods is preferably adjustable by adjustment means, such as a screw / nut system in which the rod is in two parts, a first portion ending in a threaded rod cooperating with a second part starting with a nut.

The position of the rotation points of the rod can also be adjusted by means of supports having different housings to accommodate the two axes of rotation and thus adapt for example to different connecting rod lengths, in order to ensure the correct operation of the system.

These means make it possible to correctly adjust the position of the leaf in the closed door position and in the open door position and also offer a possibility of adjusting the kinematics of the movement with respect to the implantation of the door, in particular according to the position of the door. thickness of the opening and / or its width between its vertical edges and also optimize the volume of the swept area on both sides of the door (inside / outside).

In addition, the rotation of the upper link and the lower link are preferably synchronized using a synchronization system to turn in the same way at the same time.

In a very particular variant, the link / synchronization system is unique for the synchronization of the sliding system and for the synchronization of the rotation of the rotating guide means. The link / synchronization system may consist of, for example, at least one drive shaft and / or a plurality of pulleys and / or gears driven by at least one drive means. Belt type or chain or cable (cable with pins attached to it). In another particular variant, the door according to the invention comprises at least one drive system for driving in rotation and / or for sliding driving at least one leaf.

This motorization system may, for example, be integrated with the leaf and cooperate with at least one guidance system, such as the lintel guide system or the remote guide system, in particular via a rack.

This motorization system can also cooperate with the link / synchronization system.

The door according to the invention may comprise two movable leaves, these two wings being preferably both mobile in accordance with the invention. The present invention can thus be applied not only to the cases of one-leaf doors, but also to two-opening doors cooperating with a single frame.

The present invention also relates to a device for the implementation of the door according to the invention. This device comprises at least sliding means for the rectilinear sliding of at least one vertical edge of the leaf in a horizontal direction and preferably sliding means for the rectilinear sliding of the two vertical edges of the leaf in two substantially perpendicular horizontal directions. This device furthermore preferably comprises rotation guide means for guiding a double rotation movement of the wing both on itself along a substantially central vertical axis and with respect to the frame.

The present invention also relates to the use of the door according to the invention for separating an interior space from an outside space, said leaf having a maximum space of space in opening or closing V = Hx (I - (πl) / 4) where H is the height of the wing and 1 is the width of the wing.

Advantageously, the system according to the invention makes it possible to open and close the door with a very small space requirement: space necessary to move the wing to move from the closed position to the open position and vice versa is very small.

In addition, the means to allow this movement are simple and allow great reliability, without the risk of generating a mechanical game annoying in the context of normal use of the door and in compliance with standards.

Advantageously also, the system according to the invention makes it possible to achieve a satisfactory seal to the winds in the closed position.

Advantageously also, the grouting means sits deported perpendicularly to the opening may be associated with an adjacent wall, that is to say positioned against an adjacent wall when the door is formed near a wall, for example in a corridor .

Advantageously finally, the movement can be automated easily using automated means of opening / closing simple and reliable.

It is specified that in these figures the proportions between the various elements represented are not rigorously respected and the cutting elements in the background are not always represented, in order to facilitate reading.

Figure 1 illustrates the opening or closing movement of a door (1) according to the invention.

This door (1) is provided with a fixed frame (2) thus effecting a separation between an inner space (I) and an outer space (E), and a leaf (3) movable relative to this frame.

To facilitate understanding of the invention, it will be considered hereinafter that when the leaf is in the closed position (the closed leaf is referenced: 3a) it cooperates with the frame so as to close an opening (4) made in this frame and that when the leaf is in the open position (the open leaf is referenced: 3c), it does not closes the opening (4), but is positioned substantially perpendicular to this opening, in the interior space.

For ease of understanding, it is also sometimes referred to an intermediate position where the leaf (3) is half open or half closed (the leaf in the intermediate position is referenced: 3b).

The opening movement of the leaf thus consists in moving from the closed position to the open position and the closing movement thus consists in moving from the open position to the closed position.

The leaf (3) has a main face having a substantially rectangular shape and oriented substantially vertically.

The wing (3) is thus delimited at its lateral ends by vertical edges (31, 32) and at its upper and lower ends by horizontal edges (33, 34) (not visible in Figure 1).

In the figures, reference is made to the proximal vertical edge (31a, 31c) of the leaf (3) respectively in the open (3a) and closed (3c) position, and to the distal vertical edge (32a, 32c) of the leaf ( 3) respectively in the open (3a) and closed (3c) positions.

The leaf (3) is rigid and in one piece because it is not itself articulated: the distance between these vertical edges is permanently the same. In FIG. 1, it is illustrated that said leaf (3) is animated on the one hand by a double rotation movement: a first rotation R of about 180 ° on itself along a vertical axis (30) substantially central and at the same time a second rotation R 'of the support of this axis relative to the frame of about 90 ° and secondly of a sliding movement (C1, C2) rectilinear of at least one vertical edge (31 , 32) in a horizontal direction (D1, D2) by means of sliding means and preferably a sliding movement of the two vertical edges (31, 32) in two horizontal directions (D1, D2).

The directions D1 and D2 are here perpendicular and the angle α between two directions is thus 90 °, but it is possible to orient for example the direction D1 by an angle of 80 ° to 100 ° with respect to D2, even more or less than this beach. The sliding (Cl) will then be shifted accordingly.

The central vertical axis (30) is illustrated in FIG. 1 in the position it occupies when the leaf is half open or half closed. The trajectory of this axis from the open position to the closed position or vice versa is illustrated by the two arcs of circle in large dots. The radius of these arcs is substantially equal to a quarter of the width of the door.

According to the invention, rotation guiding means are preferably provided for guiding the leaf in its double rotation on itself and with respect to the frame, but these means are not strictly indispensable: this double rotation can be achieved even in the absence of rotation guiding means.

Due to the symmetry of the leaf with respect to its central axis, any force exerted near a vertical edge of the leaf will have the same effect on the guide means in sliding, and possibly in rotation, that a force of the same intensity exerted on the other vertical edge of the wing. The reliability of the sliding guide means, and rotation possible, is thus improved.

The vertical edge (31) proximal of the leaf (3) is the one that is close to the amount of the frame that supports the second part of the rotation.

FIG. 2 illustrates a view of the horizontal horizontal sectional surface of the volume V used by the leaf during the opening or closing movement (hatched surface).

This space is defined by the two extreme positions of the leaf (3): the closed position (3a) and the open position (3b), located substantially at 90 ° according to the horizontal, and a concave arcuate curve connecting the distal vertical edge (32a) of the closed leaf (3a) at the proximal vertical edge (31c) of the open leaf (3c). The radius of curvature of this arc is substantially equal to the width of the door.

The volume thus corresponds in horizontal section to the complement of the surface of a quarter circle whose radius is the width of the leaf in a square having this radius for its side, that is to say that the total volume necessary for the movement of the leaf corresponds approximately to the formula: V = Hx (l ² - (πl ² ) / 4) where H is the height of the wing and 1 = the width of the wing.

Thus, for a leaf of a width of 1 meter, the horizontal surface in horizontal section of the volume V is 0.215 m ^2, while in European Patent Application EP ⁰ 1138861, this surface is 0.48 m ² for the same width of flap of 1 meter. Figures 3 to 5 illustrate a door according to the invention provided with sliding means in each of the two directions (D1, D2) and rotation guiding means, this door being respectively in the closed position, intermediate and open.

For the sake of simplicity, it is considered hereinafter that the means for sliding and guiding in rotation are located in the interior space.

The sliding (Cl) is offset perpendicularly to the opening (4) and the sliding (C2) is lintel, above the opening (4).

Sliding (Cl) is achieved by means of sliding means comprising a high horizontal rail (20) and a low horizontal rail (23), both perpendicular to the opening (4), and supported by two vertical posts ( 21, 22) at each of their ends.

If a wall is located perpendicular to the opening (4) and close to the frame, the rails (21, 23) can be positioned against this wall and there is no need for vertical posts. The sliding (C2) is achieved by sliding means comprising a high horizontal rail positioned in lintel, substantially in the plane of the opening (4), or in any case parallel to this plane and above the opening .

Carriages or pads attached to the vertical edges (31a, 31b, 31c, 32a, 32b, 32c) of the leaf (3a, 3b, 3c) can move easily inside the rails. The double rotation R / R 'is carried out thanks to an upper connecting rod (14) positioned in the upper part of the door, a distal end of the connecting rod (14) cooperating with a shaft (not visible in FIGS. 3 to 5) mounted on the flap and oriented along the vertical axis (30) and a proximal end of the connecting rod cooperating with a base (not visible in Figures 3 to 5) mounted on the frame (2) and oriented vertically. To pass from the closed position of FIG. 3 to the open position of FIG. 5 while passing through the intermediate position of FIG. 4, it suffices to pull or push manually on the leaf (3a) inwards. . It is then observed that: the carriage associated with the vertical edge (32) distal slides in the lintel rail towards the pole (21), the carriage associated with the vertical edge (31) distal at the top portion slides in the rail (20) offset towards the post (22), the carriage associated with the vertical edge (31) distal at the bottom part slides in the rail (23) offset towards the post (22), the rod (14) rotates R '90 ° relative to the base, and the flap (3) rotates R 180 ° relative to the rod (14). As shown in Figure 4, in the variant shown, during opening or closing, no part of the leaf (3b) enters the outer space on the other side of the frame.

No part of the leaf (3b) also protrudes during the opening or closing of the plane formed by the rails (20, 23) and the posts (21, 22).

FIGS. 6 and 7 illustrate a variant of the invention in which, as in FIGS. 3 to 5, the sliding (Cl) is achieved by means of sliding means comprising a high horizontal rail (20) and a rail (23). ) horizontal, both perpendicular to the opening (4), and supported by two vertical posts (21,

22) at each of their ends, as well as by carriages, one of which, the carriage (25) high, cooperating with the high rail (20), is visible in Figure 7 and the other, the lower carriage (25 '). ), cooperating with the low rail (23) is not visible in Figure 7.

In this variant also, the double rotation R / R 'is achieved thanks to an upper link (14) positioned respectively in the upper part of the door, a distal end of the connecting rod (14) cooperating with a shaft (35) mounted on the beating and oriented along the vertical axis (30) and a proximal end of the connecting rod cooperating with a base (24) mounted on the frame (2) and oriented vertically.

However, in this variant, no sliding means is provided for sliding of the distal vertical edge (32).

In FIG. 7 it can be seen that this vertical edge (32) "protrudes" somewhat from the leaf (3a), that is to say, protrudes from the opening (4) in the outer space during the opening or closing of the door, but this overflow is less than one fifth of the width of the door.

Figures 8 to 10 illustrate views of this system in positions where the door is not completely closed or fully open, to better show the principle of synchronization according to the invention. The proximal edge (31) of the wing is provided with two pivots, a top pivot (36) and a bottom pivot (36 ') both of which are attached to the wing and both have a vertically oriented cylinder. Each carriage (25, 25 ') has a ring which is freely rotatably mounted on each top and bottom pivot (36, 36') so that each carriage can rotate about each pivot.

Each carriage (25, 25 ') is fixed respectively to a horizontal up and down driving means (28, 28') so that any movement of a high and low carriage (25, 25 ') causes the displacement of the horizontal drive means associated therewith, respectively up and down (28, 28 ').

The high carriage (25) slides on the high rail (20) and this sliding causes the displacement of the high horizontal drive means (28) consisting of a rotating belt on itself between a rear pulley on the one hand high (26a) fixed to the rear pole (22) and movable in free rotation along a vertical axis and a front high pulley (26b) rotatable about a vertical axis.

The low carriage (25 ') slides on the low rail (23) and this sliding causes the displacement of the low horizontal drive means (28') consisting of a moving belt in rotation on itself between on the one hand a rear low pulley (26c) fixed to the rear pole (22) and movable in free rotation along a vertical axis and a low front pulley (26d) movable in rotation along a vertical axis.

The two front pulleys (26b, 26d) are fixedly mounted on a vertical drive means (29) consisting of a vertically oriented shaft and free to rotate along a vertical axis. These two front pulleys therefore rotate in the same way at the same time simultaneously during the rotation of the vertical shaft.

The two rear pulleys (26a, 26c) also turn accordingly in the same way at the same time, under the effect of their drive by the belts.

In these FIGS. 8 to 10, the connection system making it possible to permanently keep the top and bottom carriages (25, 25 ') aligned vertically thus comprises the upper and lower horizontal drive means (28, 28') to which are respectively fixed the carriages up and down (25, 25 ') but which are movable along the horizontal and the vertical drive means (29), free to rotate along a vertical axis. This vertical drive means provides the vertical mechanical connection between the upper and lower horizontal drive means (28, 28 ') so that the vertical position of a horizontal drive means up or down (28, 28 ') is always identical to the position according to the vertical of the horizontal drive means respectively low or high (28', 28). In the illustrated configuration, the two belts rotate around the front (21) and rear (22) posts, but other configurations are also possible.

In the case where the sliding (C2) in the direction (D2) is operated using one or more rails, the upper one positioned respectively in the upper part of the opening and / or the other lower positioned in the lower part of the opening, it is preferable to coordinate the movements of the (or) carriage (s) associated with each rail, vis-à-vis the frame, to synchronize their movement using a system linkage, that is to say, to ensure that a carriage of a rail has at all times the same position relative to the frame that the corresponding carriage associated with the other rail. This sliding connection system (C2) is preferably mechanically linked to the linkage system associated with sliding (C1) in the direction (D1).

Moreover, in the case where the double rotation R / R 'is operated by two rods, one upper positioned respectively in the upper part of the door and the other lower positioned in the lower part of the door, it is preferable to coordinate the rotation R 'of the rods vis-à-vis the frame, that is to say vis-à-vis the upper and lower bases, to synchronize their movement, that is to say, to ensure that they present at all times the same angular orientation with respect to the frame. It is furthermore possible to confirm the synchronization of the rotation R 'by a synchronization of the rotation R at the flap (3), by connecting the upper and lower shafts mounted on the leaf. It must be understood here that the shafts may be partly inside the leaf and that it is possible to conceal a single shaft cooperating with the upper and lower links inside the leaf. In addition, it is possible to perform a single synchronization for the synchronization of slides and the synchronization of rotations.

To do this, it is possible for example to provide a synchronization system ensuring that the carriages associated with the top rails (20) and bottom (23) sliding in the same way at the same time and that the upper and lower rods rotate in the same way. same time: using a plurality of pulleys (26) each movable along a horizontally oriented axis and driven by means of horizontal drives (28, 28 ') connected by a vertical drive means (29), all the drive means being of the belt, chain, cable type, ... as can be seen in FIG. 11 or with the aid of a plurality of gears (27) driven by horizontal drive means (28, 28 ') of the toothed belt or chain type connected by a vertical drive means (29) consisting of a vertical shaft, concealed for example inside the front post (21), as shown in FIG. 12.

The door according to the invention can also be automated so that there is no need to push or pull manually to open or close.

To do this, it may comprise at least one motorization system (10) for driving in rotation and / or for sliding driving at least one leaf (3).

FIG. 13 illustrates an exemplary embodiment of this automation in which the motorization system (10) is integrated with the leaf (3) and cooperates with at least one guide system (Sl) via a rack (44) positioned in the rail (23).

In a variant of the invention, illustrated in FIG. 14, the door comprises two leaves (3, 3 '), each being provided in this example, as for the leaf of FIGS. 6 and 7: a guide system (Sl Sl ') sliding means (Cl, Cl') comprising a high horizontal rail (20, 20 ') and a low horizontal rail (23, 23'), both perpendicular to the opening ( 4), and supported by two vertical posts (21, 22, 21 ', 22') at each of their ends, as well as by carriages, one of which, the top carriage, which is fixed to the proximal vertical edge of the leaf and which cooperating with the rail (20, 20 '), is visible in FIG. 11, with double rotation guide means comprising an upper connecting rod (14, 14') positioned at the top of the door, a distal end of the connecting rod ( 14, 14 ') cooperating with a shaft (35, 35') mounted on the leaf (here 3b, 3b ') and oriented along the vertical axis and a proximal end of the cooperating rod nt with a base (24, 24 ') mounted on the frame (2) and oriented vertically, and at least one linkage system for synchronizing the sliding (Cl or Cl') of the top and bottom carriages of at least one system of guidance (Sl or Sl ') or two linking systems for synchronizing respectively the sliding (Cl and Cl ') of the top and bottom carriages of the two guiding systems (Sl and Sl'), or when it is desired that the two leaves open in the same way in the same time: a single link system for synchronizing the two slides (Cl and Cl ') of the top and bottom carriages of the two guidance systems (Sl and Sl').

Considering that the width of a leaf (3) of the door according to the invention has a value 1, it is possible to produce different variants of the invention with a distance d between the vertical axis (30) of the double rotation and the amount of the frame relative to which is considered the second rotation R 'of the leaf about 90 °.

Which is such that: d = p x 1, with p a number> 0 and ≤ 0.5 or <0.5.

Figures 15 to 19 respectively illustrate the cases where p = 0.1; 0.2; 0.3; 0.4 and 0.5.

For each figure, different positions of the leaf (3) of the door which separates the interior I from the outside E are illustrated. In addition, the horizontal clearance area of the wing is shown hatched.

When p> 0.5, the area of horizontal deflection of the wing is in any case greater than the area obtained with p = 0.5, that is to say greater than (l ² - (πl ² ) / 4).

Furthermore, this distance d substantially corresponds to the length of the connecting rod (or rods) when (s) is (or are) present (s).

This system makes it possible to adapt the kinematics of the leaf to the indoor and outdoor space available; in some cases (for example when p = 0.4, figure 18), if the environment allows it, facilitate the access of persons with reduced mobility to the actuator (ex: handle), that these people arrive from outside or inside; in this case, for example, a person in a wheelchair can approach very close to the actuator of the wing when the latter is closed to open the leaf, without entering the volume of movement of the opening materialized by the hatches on the left-hand side at the bottom of figure 18. This person will be able to open the door fully without having to move his wheelchair. The door according to the invention can, of course, be provided with a handle system (s) and / or locking.

The present invention is described in the foregoing by way of example. It is understood that the skilled person is able to realize different variants of the invention without departing from the scope of the patent as defined by the claims.
