Description

Technical area

The present invention relates to an actuating device for opening and / or closing an opening relative to a frame. It also relates to a frame comprising such a device, intended to be placed in a building or on a building that is to say on the roof or facade of a building.

State of the art

In the broad sense, also known as building joinery, is meant an assembly comprising a frame and an opening which is movable relative to said frame, between a closed position and an open position, most often by pivoting.

In the field of roof windows, it is known to use jacks to lift the opening (s) relative to the frame. The figure 1 shows two embodiments of the state of the art.

The left part of the figure 1 shows a first embodiment in which the opening, illustrated by a leaf 100, is both shown in the closed position and in the open position on the same figure. The jack is placed on a cross member 102 between the longitudinal sides of the frame 101. The end of the rod 103a of the jack is rotatably mounted relative to the leaf. The body 104a of the cylinder is rotatably mounted on the crosspiece 102. The movable portion 103a of the cylinder is fixed on one of the transverse amounts of the opening. In the closed position, the jack is disposed along an axis perpendicular to the axis of rotation of the leaf. During an opening command, the rod 103a of the jack pushes the leaf that opens under the action of said rod. As the rod is deployed, the leaf pivots which also causes the body 104a of the jack to pivot relative to the cross-piece 102. The jack is thus disposed at the level of the bay surface and is therefore visible from the window. inside as well as outside. In addition, its perpendicular position directed inward forms a part both movable pivotally and a very large footprint.

The right part of the figure 1 shows a variant in which the body 104b of the jack is rotatably attached to a transverse side of the opening and the rod 103b is fixed to the frame in a position significantly downwardly shifted, forming a fairly visible triangle and which also represents a large size.

In both cases, the cylinders have the disadvantage of degrading the aesthetic appearance of roofs or facades and limit visibility because they unfold in the middle of the bay window area. In addition, this type of architecture has the disadvantage of generating significant constraints in the mechanical pivot connections between the various elements, in particular in the pivoting hinges between the opening and the frame, but also between the body of the cylinder and the frame or the crossbar, and between the rod of the cylinder and the opening. In the opening phase, the direction of the force of the cylinder rod changes so that the angle formed between the direction of the force generated by the cylinder and the tangential opening direction of the opening increases during the opening. As the leaf opens, the tangential component of the force of the jack decreases so that it becomes more and more difficult to open the leaf: the useful effort decreases with the increase of the leaf. opening angle, and the cylinder is almost parallel to the opening when it reaches the end of the race.

The classic solution is to use a more powerful jack to increase the useful effort allowing the opening. However, this increase in effort further increases the stresses applied on the pivot axes around the leaf which requires reinforcing parts to achieve the various mechanical links or even the frame and the opening.

However, it is for example desirous of lifting leaves, pivotally movable relative to dormant, having dimensions of about 700 to 1600 mm in a direction perpendicular to the axis of rotation, and about 900 to 2600 mm in a direction parallel to the axis of rotation. He is also anxious to be able to lift leaves with a mass of 70 kg per m ² and can withstand on the outside surface about 50 kg of snow per m ² .

Purpose of the invention

The object of the invention is to provide an actuating device for frame that can limit the aesthetic degradation and / or increase the visibility of the bay surface of roofs or facades equipped. Another object of the invention is to limit the mechanical stresses in the pivot axes of the various parts of the frame; to reduce the need for cylinder power and resistance of mechanical components; and make it possible to produce larger openings, in particular on roofs and for regions with heavy snow in technically simple and economical conditions.

Presentation of the invention

At least one of the aforementioned objectives is achieved with, according to a first aspect of the invention, a device for actuating a frame, which comprises a frame and an opening which is pivotally movable along a longitudinal axis relative to said frame. between a closed position and an open position.

In a frame as shown here, a longitudinal axis of pivoting of the opening is preferably close to a longitudinal side of the opening which moves towards the outside of the building during its opening movement.

In the following, the term "frame" means a frame or frame fixedly connected to an inner or outer wall of a building, the frame being most often rectangular in shape and having two transverse sides and two longitudinal sides. In addition, each of the four sides respectively has a bay face, defining the bay that the opening allows to open and close, so turned to the side where the glass is, and a peripheral face opposite the bay face that is to say, moving away from her in the plane of the frame. Each opening also has two longitudinal sides and two transverse sides.

In what precedes and in the following, we call "longitudinal" any direction or orientation parallel to the axis of rotation of the opening during the opening and closing movement of the opening, and "transverse" any direction or orientation perpendicular to the longitudinal direction. In addition, it is considered that the frame separates a "weather side" outside a building when it is on an outer wall, a "sheltered side" located inside the building. The term "frontal" is used to refer to any surface of the frame or window opening towards the weathering and "back" any surface of the frame or the opening turned towards "sheltered side" located inside the building.

The device comprises at least one linear actuator having a fixed part in which translate a movable part, said movable part being provided to act at least indirectly on the opening in the direction of its opening and / or closing.

• une liaison mécanique permettant au moins une rotation et une translation avec l'ouvrant,
• au moins une liaison pivot avec la partie mobile de l'actionneur, et
• au moins une liaison pivot avec le dormant.

According to the invention, the actuation device comprises a rod arranged and configured to be at least connected by:

• a mechanical connection allowing at least one rotation and one translation with the sash,
• at least one pivot connection with the movable part of the actuator, and
• at least one pivot connection with the frame.

The mechanical links pivoting the rod are made along a longitudinal axis. The term "at least one pivot connection", one or more pivotal links.

In accordance with the scientific definition of the term, and as understood from the figures and the operation described herein, the "pivot connection" is understood as performing a guide in rotation about a fixed axis relative to the parts thus connected, leaving only one degree of freedom in rotation between them.

The pivot connection thus defined between the link and the frame is thus around an axis which remains stationary relative to the rod and relative to the frame.

The pivoting of the link relative to the frame and its mechanical action relative to the opening makes it possible to limit the mechanical actions according to components of the radial type on the axes of rotation, in particular between the opening and the frame.

The actuating device comprises translational guiding means arranged on at least one transverse side of the sash, said means receiving a hinge, said means and the hinge performing the at least one rotation and the translation between the link and opening. The device according to the invention makes it possible to limit the aesthetic impact of roofs or facades and to improve visibility and / or natural lighting through the bay surface. It makes it possible to limit the stresses in the mechanical pivoting connections, in particular the stresses in the axis of pivoting between the opening and the frame, and thus allows larger dimensions and / or a greater load on the opening .

Preferably, each rod is directly connected with the frame through the pivot connection, that is to say without other intermediate articulation in the mechanical linkage chain between the rod and the frame.

• la liaison mécanique entre la biellette et l'ouvrant comprend une combinaison d'une liaison pivot, dont l'axe de pivotement passe par un point de liaison dit point d'ouvrant, et d'une liaison glissière, c'est à dire que l'axe de la liaison pivot se déplace par rapport à l'ouvrant par l'effet de la liaison glissière,
• l'axe de pivotement de la liaison pivot entre la biellette et la partie mobile de l'actionneur passe par un point de liaison dit point d'actionneur, et
• l'axe de pivotement de la liaison pivot entre la biellette et le dormant passe par un point de liaison dit point de dormant se situant entre le point d'ouvrant et le point d'actionneur.

According to a preferred embodiment:

• the mechanical connection between the rod and the opening comprises a combination of a pivot connection, whose pivot axis passes through a connection point said opening point, and a slide connection, that is to say that the axis of the pivot connection moves relative to the opening by the effect of the sliding connection,
• the pivot axis of the pivot connection between the rod and the movable portion of the actuator passes through a connection point, said actuator point, and
• the pivot axis of the pivot connection between the rod and the frame passes through a connection point said sleeping point between the opening point and the actuator point.

This embodiment has the advantage of being able to conceal the linear actuator.

According to another embodiment, the actuator point is between the sleeping point and the opening point. This embodiment has the advantage of being compact.

Preferably, the fixed part of the at least one linear actuator is fixed to the frame. Preferably, the at least one linear actuator is parallel to a transverse face of the frame. For example, the at least one actuator is arranged parallel to a bay surface or a rear surface of a transverse side of the frame. These characteristics make it possible to limit the degradation of the aesthetic appearance of roofs or facades and to improve the visibility and / or natural lighting at across the bay surface. For example, the linear actuator can be inserted into a part of the frame to hide it.

• la longueur entre d'une part l'axe de pivotement entre l'ouvrant et la biellette (point d'ouvrant) et d'autre part l'axe de pivotement entre le dormant et la biellette (point de dormant), formant un bras de levier dit d'ouvrant, et
• la longueur entre d'une part l'axe de pivotement entre le dormant et la biellette (point de dormant) et d'autre part l'axe de pivotement entre la biellette et la partie mobile de l'actionneur (point d'actionneur),

est au moins égal à un, voire supérieur à deux ou trois. Ce rapport peut évoluer en fonction de l'épaisseur du dormant, de l'effort que l'actionneur linéaire peut générer et des dimensions de l'ouvrant. Ce rapport peut varier par exemple de 2 à 8. Cette caractéristique a pour avantage de pouvoir limiter l'encombrement du dispositif d'actionnement, et donc de pouvoir le dissimuler.For example, the relationship between:

• the length between, on the one hand, the pivot axis between the opening and the link (opening point) and, on the other hand, the axis of pivoting between the frame and the link (sleeping point), forming an arm lever said opening, and
• the length between, on the one hand, the axis of pivoting between the frame and the link (sleeping point) and, on the other hand, the axis of pivoting between the link and the moving part of the actuator (actuator point) ,

is at least one, or even greater than two or three. This ratio can change depending on the thickness of the frame, the effort that the linear actuator can generate and dimensions of the opening. This ratio may vary for example from 2 to 8. This feature has the advantage of being able to limit the size of the actuating device, and thus to be able to hide it.

According to a particular embodiment, the translation guiding means are placed on a rear transverse face of the opening so that said means fit into the front face of the frame when closing. This feature allows to completely hide the actuator when the opening is in the closed position relative to the frame and improves the aesthetic appearance of the frame.

According to a preferred embodiment, the actuating device comprises at least one slider which is connected to both the opening and the link to allow rotation and relative translation. The guide means comprise at least one rail, each rail receiving a slider so that it can slide in the rail performing a translation, and the link is rotatably connected to the rail via the slider. This embodiment has the advantage of being simple and compact.

For example, the at least one linear actuator is a cylinder, preferably pneumatic with several stages. According to another embodiment, the linear actuator is an electric jack.

According to a preferred embodiment, there is provided an actuating device on each transverse side of the frame.

At least one of the aforementioned objectives is achieved with, according to a second aspect of the invention, a frame comprising a frame and an opening which is pivotally movable about a longitudinal axis of pivoting so as to be able to open and or closing relative to said frame, the frame comprising an actuating device according to one or more of the features set out above, and arranged to actuate said opening.

Description of the invention

These embodiments being in no way limiting, it will be possible in particular to make variants of the invention comprising only a selection of characteristics described hereinafter, as described or generalized, isolated from the other characteristics described, if this selection of characteristics is sufficient to confer a technical advantage or to differentiate the invention from the state of the art.

According to one embodiment of the invention, the Figures 2 to 5 illustrate a frame 1 comprising a frame 2 and an opening 3 which is pivotally movable along a longitudinal axis relative to said frame 2, between a closed position and an open position. The Figures 2, 3a and 3b show the opening 3 in the closed position relative to the frame 2 and the Figures 4a and 4b show the opening 3 in the open position relative to the frame 2. According to the embodiment shown in FIG. figure 2 , the frame 1 comprises a frame 2 having the shape of a rectangular frame and on which are arranged two openings 3 arranged side by side in a transverse direction of the frame 2: an opening 3a located to the left of the figure 2 , and another symmetrical opening 3b located to the right of the figure 2 . The frame 2 has two transverse sides 20 and two longitudinal sides 19. Similarly each opening 3 has two transverse sides 30 and two longitudinal sides 29. In the representation, the frame 1 is intended to be installed on the roof, for example placed in a map horizontal, and separating a weathering side located above a sheltered side below. The frame 2 comprises in particular a bay face 21, turned towards the opening defined by the frame, a front face 23, turned towards the outside of the building, that is to say the weather side and a rear face 24 , opposite to the front face 23. The opening comprises in particular a rear face 34 opposite the weather side and facing the front face 23 of the frame. The term "frontal" refers to any surface of the frame or window opening towards the weather side and "back" any surface of the frame or the opening towards "sheltered side" located inside the building.

For the following, it will be described the opening and / or closing of a single opening 3: the opening 3a.

With reference to Figures 2 to 5 , the frame 1 comprises an actuating device 4 to open and / or close the opening 3 relative to the frame 2. According to the preferred embodiment, the frame comprises two actuating devices, each device being arranged along a transverse side 20 of the frame 2. For the following, it will be described that a single actuator. With reference to the figure 2 , an actuating device is partly visible under a transverse side 20 of the frame 2.

The actuating device comprises at least one linear actuator 6 for opening and / or closing the opening 3 relative to the frame 2. Preferably, each linear actuator 6 is surrounded by a cover 7 in order to conceal it and improve the appearance aesthetics of the frame, or at least to reduce its aesthetic impact. To promote understanding, the hood surrounding the actuator 6 present substantially under the transverse side 30 is not represented on the Figures 2 to 5 . The at least one linear actuator has a fixed portion 61 in which translate a movable portion 62. Preferably, the at least one linear actuator is a pneumatic jack 6, here arranged so that the fixed part is the body of the jack and the moving part is the cylinder rod. According to the preferred embodiment and with reference to Figures 2 to 5 , the jack 6 is arranged parallel to the transverse side of the frame 2, or at a small angle and for example less than 10 ° or 15 °. Preferably, the jack 6 is placed under the transverse side 20 of the 2. In the representation, the body of the jack is fixed on a rear face 24 of the transverse side 20. The body 61 of the jack is fixed rotatably to the frame by means of a fixing support 63, having the shape of a triangular paw. Preferably, the jack is pneumatically stage to ensure a desired power. For example, according to one embodiment, the theoretical force of the cylinder, during the retraction of the rod, is 1400DaN.

The actuating device comprises a rod 5 arranged and configured to be mechanically connected to the opening 3, to the frame 2 and to the cylinder 6. With reference to FIGS. figures 3a , 3b , 4a and 4b the rod 5 is connected, at a so-called actuation end, with the rod 62 of the jack by a pivot connection along a longitudinal pivot axis passing through a connection point, said actuator point C. For example, the rod 62 of cylinder includes, at its end, an attachment fork to be mechanically connected with the actuating end of the rod. A rod, passing through both the fork and the actuating end of the rod, forms the longitudinal axis of pivoting, making the pivot connection.

The rod 5 is connected, at an end called opening, to the opening 3 on the one hand, by a pivot connection along a longitudinal pivot axis passing through a connection point said opening point A, and d ' on the other hand, by a sliding link. The pivot connection can be made as described above.

The rod 5 is connected to the frame 2 by a pivot connection along a longitudinal axis of pivoting through a connection point, said sleeping point B. According to the preferred embodiment, the sleeping point B is between the point d opening A and the actuator point C. This feature has the advantage of concealing the cylinder 6 of the sheltered side. The rod rotates about the axis of the pivot connection passing through the point of the frame B. This pivot axis of the sleeping point B is fixed relative to the frame regardless of the position of the opening relative to the frame or the movement of the opening relative to the frame. The pivot connection can be made as described above.

The length defined between the opening point A and the sleeping point B forms a so-called opening lever arm. The length defined between the point of frame B and the actuator point C forms a so-called actuator lever arm. The actuator lever arm is smaller than the sash lever arm. Preferably, the ratio between, on the one hand, the length defined between the opening point A and the sleeping point B, and, on the other hand, the length defined between the sleeping point B and the actuator point C, is at least three. This feature has the advantage of being able to limit the stroke of the rod 62 of the jack and the variation of inclination of the jack, and thus limit the size of the actuating device in operation. Thus, during its movement, the cylinder keeps a position almost parallel to the frame, for example less than 10 °.

The actuating device 4 comprises translation guide means 10 fixed on a transverse side 30 of the opening 3, facing the transverse side 20 of the frame. With reference to Figures 4a and 4b , the translation guiding means 10 are fixed on a rear transverse face 34 of the opening 3. According to the preferred embodiment, the translational guiding means comprise a rail 11 fixed along the rear face 34. The device actuator comprises a slider 12 arranged and configured to connect the rail 11 with the opening end of the rod 5 in a sliding connection. In this embodiment, each rail 11 receives a slider 12 so that it can slide in translation in the rail 11, which makes this slide connection. The opening end of the rod 5 is rotatably connected, via a rod serving as a longitudinal axis of pivoting, with the slider 12 which protrudes from the surface of the rail. According to another embodiment not shown, the opening end of the rod comprises a rod projecting from the opening end in a longitudinal direction of pivoting from the end of the rod, so that said rod projection cooperates directly with the rail which has a groove for receiving said rod. The rod is arranged and configured to allow both a translation and a rotation with the rail, for example a ball or cylinder trapped in the rail.

With reference to the figure 5 , the front face 23 of the frame has an opening 23a traversed by the rod 5, and possibly arranged and configured so that the translation guiding means 10 or at least the slider 12 can be inserted during closure.

The operation of the actuating device will now be described with reference to figures 3a , 3b , 4a and 4b .

In closed position (see figures 3a and 3b ), the rod 62 of the cylinder is in the extended position. When an opening command of the opening 3 relative to the frame 2, the rod 62 enters the body 61 of the cylinder. The action of the rod 62 has the effect of pulling on the actuating end and its actuation point C of the rod so as to cause the pivoting of the link 5 about the longitudinal pivot axis passing through the Sleeve point B. The link 5 makes it possible to transmit the opening force supplied by the jack. By leverage around the pivot axis at the point of dormant B (see figures 3a and 4a ), the rod 62 of the cylinder exerts on the actuating end of the rod a traction whose tangential component forms a mechanical motor action represented by the arrow Fv. This driving action causes a mechanical opening action, represented by the arrow Fb, of the opening end of the rod on the transverse side 30 of the opening. Thanks to the arrangement of the link 5 along the frame, when the opening is in the closed position, the direction of the mechanical action Fb is substantially perpendicular to the longitudinal axis of pivoting of the opening relative to the frame and therefore tangential to the path of the opening point A, at least at the beginning of the opening of the opening relative to the frame. At this time, the mechanical stresses including radial in the pivot connection between the opening and the frame are very low or nonexistent. Then during the opening (see figure 4a ), since the longitudinal axis of pivoting through the point of dormant B is shifted from the longitudinal axis of pivoting between the opening and the frame, the driving action Fb has a non-zero angle AFb with the tangential direction the trajectory of the opening point A linked to the opening 3, but which remains always low. This angle remains for example always less than 60, or even less than 45 ° or even 30 °. Even when the door is in an almost open position, this arrangement makes it possible to limit the mechanical stresses, in particular the radial stresses, in the frame and also in the hinges between the door and the door. dormant, compared to the prior art. In addition, this arrangement makes it possible to limit the mechanical stresses in the pivot and translation connection between the opening 3 and the link 5 as well as in the pivot connection between the connecting rod and the jack rod. Thus, even if the forces can be significant at the point of actuation C, at the point of frame B, and within the link 5, no significant effort is transmitted by the frame and the hinges between the opening and the cylinder .

Of course, the invention is not limited to the examples that have just been described and many adjustments can be made to these examples without departing from the scope of the invention. In addition, the various features, shapes, variants and embodiments of the invention may be associated with each other in various combinations to the extent that they are not incompatible or exclusive of each other.

The pose is possible also indoors. It is also possible with an angle varying according to the slope of the roof or the wall on which it is placed.
