Description

[0001] The invention relates to a locking system for sliding joinery of the door or window type and more particularly to such a locking system provided with a half-opening device.

[0002] The present invention will find its application in the field of building hardware and relates to locking systems for sliding joinery of the door or window type. It relates, more particularly, to such a locking system which is designed to fit into a frame and / or a leaf of said joinery, in particular without requiring the latter to be notched.

[0003] Sliding windows or French windows generally have, to ensure their locking / unlocking, a system for locking the opening on the frame or vice versa, this locking / unlocking system being controlled by the user through a control means, and allowing the opening to be locked or unlocked from the frame. These sliding windows or French windows sometimes have additional devices, here called half-openers or half-opening devices, allowing a partial opening to be set up for ventilation.

[0004] These additional devices are most often independent of the locking system, or added to it, which makes them complex to use or implement while significantly increasing costs.

[0005] In particular, document WO 2015 / 113900 A1 discloses a locking / unlocking system for windows or French windows with sliding and lifting-sliding openings, provided with a half-opening device in the form of a housing that can be fitted into the rebate of the front upright of the sliding opening. In this housing, a hook is rotatably mounted that can be actuated, using transmission means, through a rod of the locking system. This hook can occupy a retracted position in the housing or, on the contrary, a projecting position in which it emerges from the housing to cooperate with a hooking element forming a strike plate arranged correspondingly on the frame.

[0006] In an inventive approach, it is envisaged to produce a locking / unlocking system for sliding windows or patio doors equipped with a half-opening device integrated from the outset into the locking system, without significantly increasing the complexity of implementation, the cost or the complexity of use.

[0007] In an inventive approach, we are considering creating a locking system for sliding joinery, particularly for windows or French windows, which is particularly compact and fits into the opening set, ideally without notching.

[0008] The locking system according to the invention for a sliding joinery of the door or window type comprising a frame, two openings of which at least one is movable in translation relative to the frame along a sliding direction between an open position and a completely closed position. The locking system is provided with at least one control means, at least one locking element such as a striker, at least one locking device such as a locking hook or such as a locking roller and at least one half-opening device comprising a base fixed to the locking element and a movable element capable of occupying at least two distinct positions, namely, a first position in which the movable element and / or the locking element has a first anchoring point for the locking device,allowing the locking device to engage in this first anchoring point exclusively in the fully closed position of the opening leaf movable in translation, and a second position in which the movable element has a second anchoring point for the locking device, allowing the locking device to engage in this second anchoring point exclusively in a half-open position of the opening leaf movable in translation, different from the fully closed position and the open position of the opening leaf movable in translation.,

[0009] An aim of the invention is to design a locking system for sliding joinery that is able to effectively meet the constraints of known locking systems of the state of the art, which is in particular able to facilitate its use or its implementation while keeping costs low. The locking system for sliding joinery according to the invention is suitable for equipping the opening or the frame of the joinery, in particular a profile of the opening or the frame.

[0010] Alternatively, the half-opening device is integrated within the locking element, preferably within the strike plate.

[0011] Preferably, the movable element of the half-opening device is capable of being switched between the first and second positions by an operation of the control means, preferably by means of an incomplete, increased or reverse stroke of the control means.

[0012] According to one possibility, the movable element of the half-opening device is capable of being switched between the first and second positions by an independent action of the user on all or part of the movable element of the half-opening device.

[0013] According to a possible additional feature, the movable element of the half-opening device is capable of being moved between the first position and the second position by a translational movement in a direction of movement, the direction of movement preferably being parallel to the sliding direction.

[0014] According to a variant, the half-opening device further comprises at least one return means, such as a compression spring, positioned between the base and the movable element and capable of being prestressed and compressed in the direction of movement, the return means being prestressed and compressed when the movable element of the half-opening device takes the first position.

[0015] According to a preferred variant of the locking system, the base has a stop surface against which a complementary surface of the movable element bears when the movable element takes the second position, the complementary surface preferably being kept in abutment against the stop surface by the return means.

[0016] Preferably, the half-opening device comprises a guided slide capable of guiding the movable element in the direction of movement.

[0017] According to a preferred variant, the movable element of the half-opening device is capable of being moved between the first position and the second position by a pivoting movement around a pivoting axis.

[0018] According to a possible additional feature, the half-opening device comprises a holding device movable between a holding position in which the holding device holds the movable element in the first position, and a release position in which the holding device allows the movable element to move from the first position to the second position, preferably under the action of the return element.

[0019] The invention also relates to sliding joinery of the door or window type comprising a frame, two openings, at least one of which is movable in translation relative to the frame along a sliding direction between an open position and a closed position and a locking system according to the invention.

[0020] Other aims and advantages of the present invention will appear during the description which follows, relating to three exemplary embodiments.

[0021] Understanding of this description will be facilitated by referring to the attached drawings in which: [ Fig.1 ] is a schematic representation of a joinery in the form of a window equipped with a locking system for a sliding joinery according to the examples of realization; [ Fig.2A], [Fig.2B ] And [ Fig.2C ] are schematic representations of the locking system according to a first exemplary embodiment; [ Fig.3A ], [ Fig.3B] et [Fig.3C ] are schematic representations of the locking system according to a second exemplary embodiment; [ Fig.4A] et [Fig.4B ] are schematic perspective representations of the locking system according to a third exemplary embodiment; and [ Fig.4C] et [Fig.4D ] are schematic representations in perspective and in section of the locking system according to the third embodiment example.

[0022] As shown in the figures of the attached drawings, the present invention relates to a locking system for sliding joinery 0 of the door or window type.

[0023] The joinery 0 generally comprises at least two openings 1, 1', at least one of which is movable in translation along a sliding direction C between at least one open position PO and a fully closed position PF, and a frame 2. The joinery is provided with a locking system 10 according to the present application capable of taking on different configurations, so as to allow the user to position the opening 1, 1' in at least two different positions relative to the frame 2, one of which is the fully closed position and the other is a half-open position.

[0024] The locking system 10 according to the present application is provided with at least one control means 20, at least one locking element 30 such as a striker, at least one locking device 40 such as a locking hook or such as a locking roller and at least one half-opening device 50 comprising a base 52 fixed to the locking element 30 and a movable element 54 capable of occupying at least two distinct positions, namely, a first position P1 in which the movable element 54 and / or the locking element 30 has a first anchoring point for the locking device 40, allowing the locking device 40 to engage in this first anchoring point exclusively in the fully closed position PF of the opening 1, 1' movable in translation, and a second position P2 in which the movable element 54 has a second anchoring point for the locking device 40,allowing the locking device 40 to engage in this second anchoring point exclusively in a half-open position PE of the opening leaf 1, 1' movable in translation, different from the fully closed position PF and the open position PO of the opening leaf 1, 1' movable in translation.,

[0025] In order to provide at least two different positions of the movable opening 1, 1', relative to the frame 2, the locking system 10 notably comprises the half-opening device 50, dependent on the locking element 30, comprising at least one fixed base 52 and one movable element 54.

[0026] This mobile element 54 is capable of taking at least the first position P1, called withdrawal, relative to its fixed base 52, while the locking element 30 has first reliefs capable of receiving the locking device 40, such as a hook, the mobile opening 1, 1' being in the closed position PF.

[0027] In another position of the movable opening 1, 1', called the half-open position PE or half-open position, the movable element 54 can take a second position P2 in which the movable element 54 has second reliefs capable of receiving the same locking device 40.

[0028] In addition, the half-open device 50 can also allow several PE half-open positions, with or without anti-burglary security, and also integrate additional functions, such as end-of-travel stops, leaf centering, closing assistance, for example.

[0029] The first anchoring point can be either formed by the locking element 30, in particular by the first reliefs of the locking element 30, or formed by the movable element 54 or by both the locking element 30 and the movable element 54. According to a possible additional characteristic, the first anchoring point and the second anchoring point can be formed by the same notch 57 formed in the movable element 54. Thus, the first anchoring point is formed by the notch 57 when the movable element takes the first position P1 and the second anchoring point is formed by the notch 57 when the movable element takes the second position P2.

[0030] The half-opening device 50 may be integrated within the locking element 30, preferably within the strike plate. The half-opening device 50 may be an integral part of the locking element and / or fit within the volume defined by the locking element 30, preferably within the volume defined by the strike plate.

[0031] The movable element 54 of the half-opening device 50 may be capable of being switched between the first and second positions P1, P2 by an operation of the control means 20, preferably by means of an incomplete, increased or reverse stroke of the control means 20. The control element may for example be in the form of a rotary handle around an axis of rotation oriented orthogonally to a plane in which the opening 1, 1' essentially extends.

[0032] Alternatively or additionally, the movable element 54 of the half-opening device 50 may be capable of being switched between the first and second positions P1, P2 by an independent action of the user on all or part of the movable element 54 of the half-opening device 50.

[0033] The movable element 54 of the half-opening device 50 may be capable of being moved between the first position P1 and the second position P2 by a translational movement in a direction of movement D, the direction of movement D preferably being parallel to the sliding direction C. The first and second embodiments shown in the figures 2A à 3C have such a movable element 54.

[0034] The half-opening device 50 may further comprise at least one return means 56, such as a compression spring, positioned between the base 52 and the movable element 54 and capable of being prestressed and compressed in the direction of movement D, the return means 56 being prestressed and compressed when the movable element 54 of the half-opening device 50 takes the first position P1. The first and second embodiments shown in the figures 2A à 3C comprise two such return means on either side of the movable element 54.

[0035] According to the first and second embodiments, the base 52 may have a stop surface 53 against which a complementary surface 55 of the movable element 54 bears when the movable element 54 takes the second position P2, the complementary surface 55 preferably being held in abutment against the stop surface 53 by the return means 56. When the movable element 54 takes the second position P2, the return means 56 may be prestressed, preferably prestressed and compressed with a compression less significant than the compression that the return means 56 undergoes when the movable element 54 takes the first position P1.

[0036] The half-opening device 50 may further comprise a guided slide 58 capable of guiding the movable element 54 in the direction of movement D. The guided slide may comprise at least one groove and at least one protrusion of a shape complementary to the shape of the groove capable of sliding in the groove in the direction of movement D. The protrusion and the groove may extend along a direction parallel to the direction of movement D. The protrusion may be formed on the base 52 and the groove on the movable element 54 or vice versa.

[0037] The movable element 54 can be held in the second position P2, that is to say a projecting position in front of the base 52, under the action of the return means 56.

[0038] Thus, starting from an open position PO of the opening leaf 1, 1' movable in translation, the user maneuvers the opening leaf 1, 1' movable in translation until reaching the closed position PF of the opening leaf 1, 1' movable in translation, by pushing the movable element 54 towards the base 52, then actuates the control means 20 of the locking system 10 over part of its travel to engage the end of the locking device 40 in the movable element 54 without reaching the fixed base 52.

[0039] The user then opens the leaf to its half-open position PE, reached when the movable element 54 reaches the second position P2 and then completes the locking of the locking system 10 by acting on the control means 20.

[0040] The half-opening device 50 may further comprise a holding device 60 movable between a holding position PM in which the holding device 60 holds the movable element 54 in the first position P1, and a release position PL in which the holding device 60 allows the movable element 54 to move from the first position P1 to the second position P2, preferably under the action of the return element 56. The locking system 10 according to the second embodiment shown in the figures 3A à 3C comprises such a holding device 60. The holding device 60 is capable of holding the movable element 54 in the first position P1 against the action of the return means 56.

[0041] The holding device 60 may be made of folded sheet metal. The holding device 60 may extend essentially in a plane which is perpendicular to the direction of movement D and / or perpendicular to the sliding direction C. The movement of the holding device 60 between the holding position PM and the release position PL may take place in a direction perpendicular to the direction of movement D and / or perpendicular to the sliding direction C and / or parallel to the plane in which the opening 1, 1' essentially extends.

[0042] The second embodiment thus provides that the passage of the movable element 54 from the first position P1, called the retracted position, to the second position P2, called the half-open position, is done, not by a sequence of maneuvers of the locking system 10, in particular of the control means 20 of the locking system 10, but by a direct action of the user on the holding device 60, called the stop, itself holding the movable element 54 in the first position P1 against the action of the return means 56.

[0043] According to one possibility, the movable element 54 of the half-opening device 50 may be able to be moved between the first position P1 and the second position P2 by a pivoting movement around a pivot axis P. This variant is implemented in the third embodiment shown in the figures 4A à 4D .

[0044] In this third embodiment, the movable element 54 can for example be pivoted by approximately 90° to move from the first position P1 shown in the figure 4A and the figure 4C at the second position P2 shown in the figure 4B and the figure 4D .

[0045] The mobile element 54 is thus provided to be articulated in rotation around the pivot axis P on the base 52 through a bearing 51 of the half-opening device 50.

[0046] The bearing 51 may be arranged and / or the movable element 54 may have a center of gravity such that the movable element 54 is held in the first position P1 under the action of gravity.

[0047] In the figure 4A and the figure 4B , the lower part of the opening is shown on the left side of the drawing and the upper part of the opening is shown on the right side of the drawing. Conversely, in the figure 4C and the figure 4D, the lower part of the opening is shown on the right side of the drawing and the upper part of the opening is shown on the left side of the drawing.

[0048] The half-opening device 50 may further comprise a spring blade 49 capable of holding the movable element 54 in the first position P1. The movable element 54 may be provided with a notch 54'. The spring blade 49 may be provided with a shoulder 49' which is housed in the notch 54' when the movable element takes the first position P1. The spring blade 49 may be prestressed so as to hold the shoulder 49' in the notch 54'. The spring blade 49 may be manufactured from a folded sheet metal. The spring blade 49 may have a "V" or "W" shape.

[0049] In the first position P1, the first anchoring point retains the locking device 40 and the movable element 54 is prevented from pivoting around the pivot axis P because the tensile force of the locking device 40 is exerted in line with the pivot axis P.

[0050] The half-opening device 50 may further comprise a locking element 70 provided to adopt a locking position PB in which the movable element 54 is held in the second position P2, that is to say in its half-open position, if applicable, against the action of gravity acting on the movable element 54. The locking element 70 may comprise elastic return means 72 arranged and prestressed to hold the locking element 70 in the locking position PB. To allow the movable element 54 to move from the first position P1 to the second position P2 and / or from the second position P2 to the first position P1 by pivoting about the pivot axis P, where appropriate, under the effect of gravity acting on the movable element 54, the user moves the locking element 70 against the action of the elastic return means 72 to move the locking element 70 from the locking position PB to a retracted position.

[0051] According to the third embodiment, the mobile element 54 may have a first notch 57 forming the first anchoring point when the mobile element 54 takes the first position P1 and a second notch 57' forming the second anchoring point when the mobile element 54 takes the second position P2.

[0052] The half-opening device 50 may also, preferably on the base 52, have reliefs 59 and / or fixing means 59' allowing it to ensure a secure and / or reversible fixing on the profile of the opening 1, 1' or of the frame 2 of the joinery 0.

[0053] The advantages arising from the present invention are substantial. In particular, the locking system can equip an existing sliding joinery by replacing the existing locking system with a locking system 10 according to the present application.
