Description

Title of the invention: Universal system for controlling the opening of a window Technical field

[0001] The present invention relates to the field of equipment for openings, in particular of the window or French window type, usable in the building sector. It relates to a device for controlling the degree of opening of a window or French window.

[0002] One application relates to windows or French windows comprising at least one opening mounted to rotate relative to a frame. STATE OF THE ART

[0003] There are several systems for controlling the opening of a window. These systems typically include a compass to limit the opening of the opening relative to the window frame. However, the articulation of this compass with the opening and the window frame cannot be achieved in the same way on all windows. Indeed, no standard requires manufacturers to integrate specific hardware parts in specific positions into the openings or frames of windows. Thus, when installing an opening control system on a window, the installer must adapt to the hardware parts present. Not all systems are compatible with all hardware, and very often, even when they are, adjustments are necessary to allow the system to be correctly fixed.

[0004] There is therefore a need for a system for controlling the opening of a window which at least partially overcomes this constraint. SUMMARY

[0005] To achieve this objective, a first object of the invention relates to a system for opening and closing a window opening relative to a window frame, comprising: a. A first fixed headboard capable of being fixed to the frame, b. A compass having a first end fixed to the first fixed headboard and a second end, c. A body comprising a second fixed head adapted to be fixed to the opening, the body further comprising a movable head and a slide fixed to the movable head and adapted to receive and guide in translation the second end of the compass.

[0006] The fact that the slide is integrated into the body of the system and that this body is separate from the window opening allows for universality of the system. Indeed, by means of By using suitable hooks, the body can be fixed to the opening regardless of the hardware parts on the opening. Thus, the system according to the invention can be used on a very large number of windows. This greatly facilitates the installation of the system and reduces costs for the manufacturer, who is no longer forced to produce as many control systems as there are types of hardware that can be found on the openings.

[0007] A second aspect of the invention relates to a window comprising an opening frame, a frame and a system for opening and closing said opening frame of said window relative to said frame of said window according to the present invention. BRIEF DESCRIPTION OF THE FIGURES

In particular, the dimensions are not representative of reality. DETAILED DESCRIPTION

[0019] Before beginning a detailed review of embodiments of the invention, optional features which may possibly be used in combination or alternatively are set out below:

[0020] According to one example, the body comprises at least two hooks for fixing the movable headrest to at least one piece of hardware present on the opening. The hardware present on the opening may in particular comprise a cremone bolt and / or an angle gear.

[0021] According to one example, the at least two hooks comprise at least one male hook and at least one female hook.

[0022] According to one example, the system further comprises a stop piece housed in the slide and capable of being placed in one of several different positions in the slide so as to modulate the travel that can be traveled by the second end of the compass in the slide.

[0023] According to one example, the stop piece comprises a protrusion and a locking element, the protrusion and the locking element forming a housing, the stop piece being configured so that, when the second end of the compass is against the protrusion and a pushing force is applied to the second end in the direction of the protrusion, the protrusion moves from a locking position to a passage position so that the second end of the compass passes into the housing, then, once the second end is in the housing, the protrusion moves from the passage position to the locking position.

[0024] According to one example, the locking element is configured to stop the travel of the second end of the compass in the slide.

[0025] According to one example, the projection is configured to, when the second end of the compass is in the housing, prevent the second end from exiting the housing under the effect of a thrust force of the second end on the projection less than a predetermined threshold.

[0026] According to one example, the advance is a spring whose rest position corresponds to the blocking position.

[0027] According to one example, the system further comprises clamping means, the stop piece being able to be secured to the slide in one of the different positions by said clamping means.

[0028] According to one example, the movable headrest is: a. adapted to cooperate with a window handle, so that when the window handle moves from a first position to a second position, and vice versa, the movable headrest moves from a retracted position to an engaged position, and vice versa, b. adapted to cooperate with the slide, so that when the movable headrest passes from the retracted position to the engaged position, and vice versa, the slide passes from an entangled position, in which the second end of the compass is engaged in the slide, to a free position, in which the second end of the compass is not engaged in the slide, and vice versa.

[0029] A reference frame, preferably orthonormal, comprising the axes X, Y, Z is shown in figures 5A to 5C. The Z direction may be designated “vertical direction Z”. The plane defined by the X and Z directions may be designated “main plane XZ” or “plane of the window XZ”. The notions of height and “top” and “bottom” of an element will be defined according to the vertical direction Z, it being understood that the height along Z is all the greater the further one moves away from the ground of the environment in which the system is located.

[0030] The present invention can be fitted to a window or a French window, for example made of aluminum, plastic and / or wooden joinery. The invention finds a particularly advantageous application for casement assemblies.

[0031] The system 1 according to the invention will now be described with reference to FIGS. 1 to 4.

[0032] The system 1 is intended to be installed on the one hand on an opening 100 of a window 10 and on the other hand on a frame 200 of this same window 10. The opening 100 is preferably also mounted in rotation relative to the frame 200 around a first axis of rotation Ab.

[0033] The opening 100 comprises a handle 500 mounted on the opening 100 in a pivoting manner. The handle 500 can pivot about an axis of rotation A2.

[0034] The system 1 is configured to be able to allow the opening and closing of the window 10 in two modes: a mode called “classic mode” and a mode called “ventilation mode”. The operation of the system 1 in each of these two modes as well as the transition from one mode to the other will be explained further.

[0035] The system 1 comprises a first fixed head 210 capable of being fixed to the frame 200 of the window 10 and a body 110 comprising a second fixed head 120 capable of being fixed to the opening 100 of the window 10. The body 110 is therefore itself fixed to the opening 100 by means of the second fixed head 120. The body 110 is typically fixed to the opening 100 by one or more screws.

[0036] The body 110 further comprises a movable headrest 160 and a slide 130. The movable headrest 160 and the slide 130 are connected to each other so that a translational movement in the vertical direction Z causes a translational movement in the vertical direction Z of the slide 130. The slide 130 typically defines a cavity 131 as well as a groove 132 and an opening 133, also designated inlet 133, both in communication with the cavity 131. The inlet 133 is preferably located at one end of the slide 130 and of the groove 132. It corresponds to the start of the travel of the slide 130.

[0037] The system 1 further comprises a compass 300. This compass 300 has a body 303 extending mainly along a longitudinal dimension. The compass 300 also has a first end 301 and a second end 302 located on either side of the body 303.

[0038] The first end 301 is fixed to the fixed head 210 at a fixing point 211. The compass 300 is movable relative to the fixed head 210 and to the frame 200: it can be moved in a rotating manner around the fixing point 211.

[0039] The second end 302 of the compass 300 has a shape that can be received and guided in translation by the slide 300. The second end 302 can for example have a first portion whose dimensions allow it to pass through the inlet 133 and to be housed in the cavity 131 of the slide 130, and a second portion whose dimensions allow it to be inserted and to slide in the groove 132. The second portion can be designated a narrowing.

[0040] The second end 302 of the compass 300 can thus be inserted into the slide 130 or removed from the slide 130 at will, depending on the opening mode in which the user wishes to open the window 10.

[0041] It should be noted that the inlet 133 of the slide 130 may be located at the top of the slide 130, as shown in FIGS. 1A, 1B, 3 and 4, but also at the bottom of the slide (example not shown). In other words, the slide 130 may have an inlet 133 facing the ceiling or facing the floor of the room in which the window is located.

[0042] Figures 5A to 5C illustrate the different operating modes of the system 1 according to the invention. The following paragraphs describe these operating modes, the transition from one to the other and the position of the different elements of the system 1 in each of these modes.

[0043] A mobile reference frame X'Y'Z' is defined, formed by the directions X', Y' and Z'. This reference frame is mobile relative to the XYZ reference frame and fixed relative to the opening 100. In particular, when the opening 100 undergoes a rotation around the rotation axis Ab, the mobile reference frame X'Y'Z' undergoes the same rotation around Ab. During the rotation of the mobile reference frame X'Y'Z', the axes Z and Z' remain parallel.

[0044] The directions X' and Z' define a plane called the plane of the opening X'Z', parallel to which the opening 100 mainly extends. The positions that can be taken by the handle 500 are defined in projection in the plane of the opening X'Z'. The handle 500 has a longitudinal dimension forming with the vertical direction Z', in projection in the plane of the opening X'Z', an angle called the control angle a.

[0045] The plane of the opening X'Z' and the main plane XZ together form an angle, called opening angle 0. As will appear later, the values ​​that can be taken by the opening angle 0 differ depending on the operating mode in which the system 1 is found.

[0046] [Fig.5A] shows a situation in which the window 10 is closed. In this situation, the opening 100 and the frame 200 of the window 10 both extend mainly in the same plane, the main plane XZ and the plane of the opening X'Z' are thus merged. Thus, the opening angle 0 is zero.

[0047] In this situation, the handle 500 can take different positions. In particular, it can be in a position Po allowing the opening 100 to be locked with the frame 200. Typically, when it is in the position Po, the handle 500 maintains a locking and unlocking mechanism of the window 10 in a position allowing this locking. Conventionally, when the handle 500 is in the position Po, it forms a control angle a substantially equal to 180°.

[0048] When the handle 500 is in the Po position, the second end of the compass 300 is typically inserted into the slide 130.

[0049] When the window 10 is closed, the compass 300 is housed between the opening 100 and the frame 200. The longitudinal dimension of the body 303 of the compass 300 then extends substantially in the vertical direction Z.

[0050] The handle 500 can also be placed in a position Pi or a position P2, depending on the operating mode in which the user intends to open the window 10. These positions Pi and P2 will be described in more detail with reference to FIGS. 5B and 5C. It is understood that, to move from one position to the other, the handle 500 can take all the intermediate positions between the two positions in question, that is to say that it can form with the vertical direction Z all the angles included between the two angles characterizing the two positions.

[0051] [Fig.5B] illustrates the operation of system 1 according to ventilation mode.

[0052] To operate the system 1 in ventilation mode, the user positions the handle 500 in a first position denoted Pb

[0053] Conventionally, the first position Pi of the handle 500 is characterized by a control angle a substantially equal to 90°.

[0054] Moving the handle 500 into the first position Pi allows the body 110 - and therefore the slide 130 - to be moved relative to the opening 100 so as to place the second end 302 of the compass 300 in a so-called entangled position. In the entangled position, the second end 302 of the compass 300 is engaged in the slide 130 and, when the user moves the opening 100 in rotation around the axis of rotation Ai, the second end 302 of the compass 300 moves in the slide 130.

[0055] For example, the passage from the position Po to the first position Pi of the handle 500 can cause the descent in the vertical direction Z of the movable headrest 160. This descent thus makes it possible to level in the vertical direction Z the second end 302 of the compass 300 with the inlet 133 of the slide 130, or even to place the second end 302 in a position engaged in the groove 132. It is understood that the slide 130 can be oriented in the opposite direction to that shown in the figures (inlet 133 downwards rather than upwards). The passage from the position Po to the first position Pi will then be configured rather to cause a rise of the body 110 in the vertical direction Z.

[0056] When the second end 302 of the compass 300 is guided in translation in the slide 130, its first end 301 being fixed in a rotatable manner at the level of the fixed head 210, the compass 300 follows a rotational movement around its second end 302.

[0057] When the second end 302 of the compass 300 reaches the end of its travel in the slide 130, the opening 100 cannot be moved further away from the frame 200. Thus, in the ventilation mode, the opening angle 0 is limited to a maximum value noted 0max,i- As will be presented later, means exist for modulating the system 1 so as to modulate 0max>i. Typically, 0max>i is less than 60°, preferably less than 30°, preferably less than 20°, for example less than 10°.

[0058] Placing the system in ventilation mode makes it possible to limit the opening of the window 10. This can be particularly useful for carrying out ventilation and regulating its extent.

[0059] [Fig.5C] illustrates the operation of system 1 according to the classic mode.

[0060] To operate the system 1 in the classic mode, the user positions the handle 500 in a second position noted P2.

[0061] Conventionally, the second position P2 of the handle 500 is characterized by a control angle a substantially equal to 0°.

[0062] Moving the handle 500 into the second position P2 makes it possible to move the body 110 - and therefore the slide 130 - relative to the opening 100 so as to place the second end 302 of the compass 300 in a so-called free position. In the free position, the second end 302 of the compass 300 is not engaged in the slide 130.

[0063] For example, the transition from position Pi to the second position P2 of the handle 500 can cause the body 110 to descend in the vertical direction Z. This descent thus makes it possible to place the second end 302 of the compass 300 at a higher height in the vertical direction Z relative to the inlet 133 of the slide 130. It is understood that the slide 130 can be oriented in the opposite direction to that shown in the figures (inlet 133 downwards rather than upwards). The transition from position Pi to the first position P2 will then be configured to cause the body 110 to rise in the vertical direction Z.

[0064] The compass 300 no longer limits the movement of the opening 100, the latter can thus be moved away from the frame 200 as far as its rotation system around the rotation axis Ab allows. Thus, in the conventional mode, the opening angle 0 can be between 0° and 180°, typically between 0° and 150°.

[0065] The following paragraphs focus in particular on describing the fixing of the system 1 on the opening 100.

[0066] The system 1 has the particularity of comprising a body 110 on which the slide 130 is mounted. The slide 130 is therefore not directly integrated into the opening 100. It is included in the body 110 which itself is capable of being fixed to the opening 100 by means of the second fixed head 120. For this reason, the body 110 can be designated by the English term “by-pass”, which can be translated as “derivation”.

[0067] As illustrated in Figures 2A, 2B and 3, the body 110 typically comprises at least two hooks 140 allowing the attachment of the movable headrest 160 to one or more fitting parts 600 present on the opening 100. It is typically provided that at least one hook 140 is of the male type and that at least one hook is of the female type. Preferably, the hooks 140 are located on either side of the movable headrest 160 according to its longitudinal dimension.

[0068] The fitting 600 available on the opening 100 can be of all kinds. From one window to another, depending on the manufacturers and according to local standards and customs, the fitting parts found on the opening 100 are not the same.

[0069] The hooks 140 can therefore be chosen and modulated according to the fitting located on the opening 100 of the window on which the system 1 is to be installed.

[0070] The use of hooks 140 therefore gives the system 1 a universality that does not exist in no other system for controlling the opening and closing of a window.

[0071] The attachment of the movable headrest 160 to the fittings 600 present on the opening 100 typically makes it possible to synchronize the movement of the handle 500 and the body 110 with locking and unlocking mechanisms of the window 10.

[0072] These fittings 600 advantageously have secondary hooks 140' complementary to the hooks 140 of the system 1 to allow easy fixing of the mobile headrest 160 with these fittings 600. The fittings 600 advantageously comprise fittings such as angle drives, which can be described as extension fittings.

[0073] Another separable aspect of the invention relates to a stop piece 150. This stop piece 150 is illustrated, among other things, in [Fig.4].

[0074] The stop piece 150 comprises in particular a projection 151 and a blocking element 152. These two portions 151, 152 of the stop piece 150 together form a housing 153. The projection 151 defines for example a concave surface facing the housing 153.

[0075] The housing 153 is configured to be able to accommodate an external element abutting firstly against the projection 151. Under the effect of a thrust force applied to the external element, the latter causes the projection 151 to pass from a blocking position, into which it played a role of stop for the external element, at a passage position. When the advance 151 passes into the passage position, the external element can be inserted into the housing 153. The blocking element 152, itself, has a higher resistance to deformation than the advance 151 and then prevents the external element from continuing its travel.

[0076] Once the external element is in the housing 153 and as long as a reverse force greater than a predetermined threshold is not applied to the external element, the latter is blocked on the one hand by the blocking element 152 and on the other hand by the projection 151. To make the external element come out of the housing 153, the user applies a force greater than the predetermined threshold on the external element, in the direction of the projection 151. Again, the projection 151 then passes from its blocking position to its passage position, thus allowing the external element to come out of the housing 153. Once the external element has come out of the housing 153, the projection 151 repositions itself in its blocking position.

[0077] The advance 151 is typically a spring. The rest position of this spring then corresponds to the blocking position of the advance 151. The passage position corresponds to a compressed state of the spring.

[0078] The stop piece 150 can be perfectly integrated into the slide 130 of the system 1 according to the invention. In this context, the stop piece 150 is intended to stop the travel of the second end 302 of the compass 300 within the slide 130. It makes it possible to retain the second end 302 within the housing 153 as long as a force greater than the predetermined threshold is not applied to the end of the slide 302 to cause it to come out of the housing 153.

[0079] The stop piece 150 is fixed to the slide 130 by fixing means 155 such as screws.

[0080] It is advantageously provided that the stop piece 150 can be placed in different positions within the slide 130 in order to modulate this stroke. With this in mind, it is provided that the fixing means 155 are easily engaged and disengaged in order to be positioned at different levels of the slide 130.

[0081] The fact of being able to change the position of the stop piece 150 in the slide 130 and therefore being able to modulate the travel of the second end 302 of the compass makes it possible to modulate the maximum value 0max>i of the opening angle 0 of the opening 100 relative to the frame 100. Thus, 0max>i can be adjusted according to the needs of the user and / or according to the environment in which the window is located, in particular according to the desired degree of ventilation.

[0082] For example, it may be desired that the opening angle 0 be small if it is desired to achieve ventilation through the window 10 in complete safety, for example in the presence of children or animals or when the window 10 is located on a high floor of a building. A small opening may also be advantageous if it is necessary to Pass certain elements through window 10, for example, the exhaust pipe of an air conditioner. Low continuous ventilation may also be desired when chemicals are used in the room in which window 10 is located but a strong draft would be dangerous, for example in a chemistry laboratory. Finally, low continuous ventilation may provide some regulation of the humidity in the room.

[0083] Through the different embodiments described above, it appears clearly that the invention proposes a universal solution allowing the control of the opening of a window.

[0084] The invention is not limited to the embodiments previously described and extends to all embodiments covered by the invention.
