Description

Title of the invention: Universal window opening control system technical field

[0001] The present invention relates to the field of equipment for openings, particularly 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] Several window opening control systems exist. These systems typically include a stay mechanism that limits the opening of the sash relative to the window frame. However, the articulation of this stay mechanism with the sash and frame cannot be achieved in the same way on all windows. Indeed, no standard requires manufacturers to integrate specific hardware components in precise positions within the window sashes or frames. Thus, when installing an opening control system on a window, the installer must adapt to the existing hardware. Not all systems are compatible with all hardware, and often, even when they are, modifications are necessary to ensure proper installation of the system.

[0004] There is therefore a need for a window opening control system that is at least partially free from this constraint. SUMMARY

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

[0006] The fact that the sliding mechanism is integrated into the body of the system and that this body is separate from the window sash allows for the universality of the system. Indeed, by means of By using suitable fasteners, the body can be attached to the sash regardless of the hardware present on the sash. Thus, the system according to the invention can be used on a very large number of windows. This greatly simplifies installation and reduces costs for the manufacturer, who is no longer required to produce as many control systems as there are types of hardware found on the sashes.

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

[0019] Before proceeding with a detailed review of embodiments of the invention, optional features that may be used in combination or alternatively are listed below:

[0020] According to one example, the body includes at least two hooks for attaching the movable head to at least one piece of hardware present on the opening. The hardware present on the opening may include, in particular, a cremone bolt and / or a corner drive.

[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 includes a stop piece housed in the slide and suitable for being placed in one of several different positions in the slide so as to modulate the stroke that can be traveled by the second end of the compass in the slide.

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

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

[0025] According to one example, the advance is configured so that, when the second end of the compass is in the housing, it prevents the second end from coming out of the housing under the effect of a thrust force from the second end on the advance below 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 includes 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. capable of cooperating 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. able to cooperate with the slide, so that when the movable head moves from the retracted position to the engaged position, and vice versa, the slide moves 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 coordinate system, preferably orthonormal, comprising the X, Y, and Z axes is shown in Figures 5A to 5C. The Z direction may be designated as the "vertical Z direction." The plane defined by the X and Z directions may be designated as the "principal XZ plane" or the "XZ window plane." The concepts of height and "top" and "bottom" of an element will be defined according to the vertical Z direction, it being understood that the height along Z is greater the further one moves from the ground of the environment in which the system is located.

[0030] The present invention can be used to equip a window or French window, for example, made of aluminum, plastic, and / or wood. The invention is particularly advantageous for casement assemblies.

[0031] System 1 according to the invention will now be described with reference to Figures 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 fixed frame 200 of the same window 10. The opening 100 is preferably also mounted to rotate relative to the fixed frame 200 about a first axis of rotation Ab

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

[0034] System 1 is configured to allow the window 10 to be opened and closed in two modes: a "classic mode" and a "ventilation mode". The operation of system 1 in each of these two modes, as well as the transition from one mode to the other, will be explained later.

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

[0036] The body 110 further comprises a movable head 160 and a slide 130. The movable head 160 and the slide 130 are connected such that a translational movement along the vertical direction Z results in a translational movement along the vertical direction Z of the slide 130. The slide 130 typically defines a cavity 131, a groove 132, and an opening 133, also referred to as the inlet 133, both of which communicate with the cavity 131. The inlet 133 is preferably located at one end of the slide 130 and the groove 132. It corresponds to the beginning of the stroke of the slide 130.

[0037] System 1 further comprises a compass 300. This compass 300 has a body 303 extending primarily 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 mobile relative to the fixed head 210 and the frame 200: it can be moved in a rotational 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 may, for example, have a first portion whose dimensions allow it to pass through the opening 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 may be designated as the 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 entrance 133 of the track 130 can be located at the top of the track 130, as shown in Figures IA, IB, 3 and 4, but also at the bottom of the track (example not shown). In other words, the track 130 can have an entrance 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 system 1 according to the invention. The following paragraphs describe these operating modes, the transition from one to another, and the position of the different elements of system 1 in each of these modes.

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

[0044] The directions X' and Z' define a plane called the opening plane X'Z', parallel to which the opening 100 extends mainly. The positions that can be taken by the handle 500 are defined in projection onto the opening plane X'Z'. The handle 500 has a longitudinal dimension forming with the vertical direction Z', in projection onto the opening plane 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 the opening angle 0. As will be shown later, the values ​​that can be taken by the opening angle 0 differ depending on the operating mode in which the system 1 is located.

[0046] Figure 5A represents a situation in which the window 10 is closed. In this situation, the sash 100 and the frame 200 of the window 10 both extend primarily in the same plane; the principal plane XZ and the plane of the sash X'Z' thus coincide. Therefore, the opening angle 0 is zero.

[0047] In this situation, the handle 500 can assume different positions. In particular, it can be in a position Po allowing the opening 100 to be locked with the frame 200. Typically, when in the Po position, the handle 500 maintains a locking and unlocking mechanism for the window 10 in a position that allows this locking. Typically, when the handle 500 is in the Po position, it forms an operating angle α of approximately 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 fixed 200. The longitudinal dimension of the body 303 of the compass 300 then extends substantially along 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 according to which the user intends to open the window 10. These positions Pi and P2 will be described in more detail with reference to Figures 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, it can form with the vertical direction Z all the angles between the two angles characterizing the two positions.

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

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

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

[0054] Moving the handle 500 to 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 an entangled position. In the entangled position, the second end 302 of the compass 300 is engaged in the slide 130 and, when the user rotates the opening 100 around the axis of rotation Ai, the second end 302 of the compass 300 moves within the slide 130.

[0055] For example, moving the handle 500 from position Po to the first position Pi can cause the movable head 160 to descend in the vertical direction Z. This This descent allows the second end 302 of the compass 300 to be leveled along the vertical Z direction with the inlet 133 of the slide 130, or even to be placed 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 transition from position Po to the first position Pi will then be configured to cause the body 110 to rise along the vertical Z direction.

[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 rotational 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 track 130, the sash 100 cannot be moved any further from the frame 200. Thus, in ventilation mode, the opening angle 0 is limited to a maximum value denoted 0max>i. As will be shown 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 allows the opening of window 10 to be limited. 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 classical mode.

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

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

[0062] Moving the handle 500 to the second position P2 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 free position. In the free position, the second end 302 of the compass 300 is not engaged in the slide 130.

[0063] For example, moving the handle 500 from position Pi to the second position P2 can cause the body 110 to descend along the vertical direction Z. This descent allows the second end 302 of the compass 300 to be positioned higher along 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). Moving the handle 500 from position Pi to the first position P2 will then be configured to cause the body 110 to rise along the vertical direction Z.

[0064] Since 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 axis of rotation Ab allows. Thus, in the classic mode, the opening angle 0 can be between 0° and 180°, typically between 0° and 150°.

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

[0066] 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 sash 100. It is included in the body 110 which itself is able to be fixed to the sash 100 by means of the second fixed faceplate 120. For this reason, the body 110 can be designated by the English term "by-pass", which can be translated as "bypass".

[0067] As illustrated in Figures 2A, 2B, and 3, the body 110 typically includes at least two hooks 140 for attaching the movable faceplate 160 to one or more hardware pieces 600 present on the opening 100. Typically, at least one hook 140 is male and at least one is female. Preferably, the hooks 140 are located on either side of the movable faceplate 160 along its longitudinal dimension.

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

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

[0070] The use of 140 hooks therefore gives 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 head 160 to the fittings 600 present on the opening 100 typically allows the movement of the handle 500 and the body 110 to be synchronized with the 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 attachment of the movable head 160 with these fittings 600. The fittings 600 advantageously include 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 includes, in particular, a projection 151 and a locking element 152. These two portions 151, 152 of the stop piece 150 together form a dwelling 153. The projection 151 defines for example a concave surface in relation to the dwelling 153.

[0075] The housing 153 is configured to accommodate an external element that initially abuts against the extension 151. Under the effect of a thrust force applied to the external element, the latter moves the extension 151 from a blocking position, in which it acted as a stop for the external element, to a passage position. When the extension 151 moves into the passage position, the external element can be inserted into the housing 153. The blocking element 152, however, has a higher resistance to deformation than the extension 151 and thus prevents the external element from continuing its movement.

[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, it is blocked on one side by the blocking element 152 and on the other side by the extension 151. To remove the external element from the housing 153, the user applies a force greater than the predetermined threshold to the external element, in the direction of the extension 151. Again, the extension 151 then moves from its blocking position to its passage position, thus allowing the external element to exit the housing 153. Once the external element has exited the housing 153, the extension 151 returns to 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 movement of the second end 302 of the compass 300 within the slide 130. It allows the second end 302 to be retained within the housing 153 as long as a force exceeding the predetermined threshold is not applied to the end of the slide 302 to force it out of the housing 153.

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

[0080] Advantageously, the stop piece 150 can be placed in different positions within the slide 130 in order to modulate this stroke. To this end, the fastening means 155 are easily engaged and disengaged so as to be positioned at different levels of the slide 130.

[0081] The ability to change the position of the stop piece 150 in the slide 130, and thus to modulate the stroke 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 sash 100 relative to the frame 100. Thus, 0max>i can be adjusted according to the requirements of the user and / or depending on the environment in which the window is located, in particular depending on the desired degree of ventilation.

[0082] For example, a small opening angle 0 may be desirable if safe ventilation is required through window 10, for instance, in the presence of children or animals, or when window 10 is located on a high floor of a building. A small opening may also be advantageous if certain components need to pass through window 10, such as the exhaust hose of an air conditioner. Low continuous ventilation may also be desirable when chemicals are used in the room containing window 10, but a strong draft would be dangerous, for example, in a chemistry laboratory. Finally, low continuous ventilation can help regulate the humidity in the room.

[0083] Through the different embodiments described above, it is clear that the invention offers 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.
