Title of the invention: Device for returning a bolt for a carpentry locking system
[0001] The invention relates to a bolt return device for a locking system of a joinery.
[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 designed to fit into a frame and / or a leaf of said joinery, in particular without requiring the latter to be notched.
[0003] Window or French window type joinery generally has a frame, at least one opening leaf and, to ensure the locking / unlocking of the joinery, a system for locking the opening leaf on the frame or vice versa, most often operated by means of a manual operating means, such as a handle.
[0004] However, these operating means are generally centered on an upright, or even a crosspiece, forming the frame of the opening or the fixed frame. In the case of a window or French window with two openings, the operating means may therefore be offset from the axis of symmetry of these openings, if it is mounted on an upright of the opening, since each opening is respectively formed of an individual frame.
[0005] Devices already exist for centering the installation of these operating means substantially in the axis of symmetry of the two-leaf joinery, for example on an element of the frame of a first opening among the two openings projecting from the upright or crosspiece of the first opening and partially covering the upright or crosspiece of the frame of a second opening among the two openings. These devices make it possible to center the installation of these operating means through a mechanism inserted between the locking system and the operating means, commonly referred to as a "follower return" or the term follower return device.
[0006] These follower return devices are generally symmetrical by design, to allow them to be mounted on joinery with right-hand or left-hand fittings. In their most widespread form, follower return devices are provided with one or more gears for transmitting the force supplied by the operating means to the locking system. A first axis of rotation of a control member of the locking system, such as a toothed wheel generally called a "follower", and a second axis of rotation of a means of The carpentry maneuvers are thus offset in the main plane of the carpentry. However, these characteristics generally lead to poorly defined end-of-travel positions of the maneuvering means, for example open or closed, due to the sum of the clearances introduced by the gears and the symmetry of the follower return device, which generate clearances in both possible operating directions.
[0007] However, these poorly defined positions then cause an unsightly misalignment of the operating means in relation to the crosspieces with which it is fitted. In addition, these poorly defined positions sometimes interfere with the mechanical indexing with which certain operating means are equipped, to identify particular positions, in particular, at 90° or 180°.
[0008] In an inventive approach, it is then envisaged to produce a means for limiting the stroke of the operating means, capable of equipping such a follower return, so as to guarantee an end-of-stroke positioning of the operating means, open or closed, perfectly aligned with the crosspiece with which it is equipped. The operating means can be integrated into the follower return, or even be removable or even added a posteriori without intervention on the follower return or the operating means or the locking system.
[0009] The follower return device according to the invention is intended to equip a locking system of a joinery comprising a control member, a locking element such as a striker and a locking device such as a locking hook or such as a locking roller movable as a function of a rotation of the control member.The follower return device comprises a housing, a transmitting member housed in said housing and capable of pivoting about a first axis of rotation and a receiving member housed in said housing and capable of receiving a first part of a means for operating the joinery, said receiving member being housed in said housing so as to be capable of pivoting about a second axis of rotation, the follower return device further comprising one or more gears making it possible to transform the pivoting of the receiving member about the second axis of rotation into a pivoting of the transmitting member about the first axis of rotation.The follower return device according to the invention comprises a sheath capable of receiving a second part of the operating means and capable of pivoting around the second axis of rotation and a means for limiting the travel of the operating means and / or the sheath capable of limiting the travel of the pivoting around the second axis of rotation of the operating means and / or the sheath between a first end position of the pivoting travel and a second end position of the pivoting travel.
[0010] One aim of the invention is to guarantee that the end of travel of the operating means, whether open or closed, is perfectly aligned with the crosspiece with which it is fitted.
[0011] According to one possibility, the travel limiting means is fixed to the housing or integrated into the housing.
[0012] In the case where the travel limiting means is integrated into the housing, the travel limiting means may constitute a wall of the housing.
[0013] Preferably, the first axis of rotation is parallel to the second axis of rotation and / or not aligned with the second axis of rotation.
[0014] According to one possibility, the sheath comprises a protrusion projecting in a direction orthogonal to the second axis of rotation provided with a first stop surface. According to an alternative, the sheath comprises a recess in the shape of an arc of a circle delimited by two ends, a first stop surface being formed at a first end among the ends of the recess.
[0015] According to a possible additional characteristic, the travel limiting means comprises a first stop surface, the first stop surface coming to bear against the first stop surface when the operating means takes the first end-of-travel position.
[0016] According to a variant, the travel limiting means comprises a second stop surface and the protrusion is provided with a second stop surface. According to an alternative, a second stop surface is formed at a second end opposite the first end of the recess. The second stop surface bears against the second stop surface when the operating means takes the second end-of-travel position.
[0017] According to one possibility, the second stop surface may be parallel to the first stop surface and / or the second stop surface may be parallel to the first stop surface.
[0018] According to a possible additional characteristic, the second stop surface may be orthogonal to the first stop surface and / or the second stop surface may be orthogonal to the first stop surface.
[0019] According to a preferred variant of the follower return device, the travel limiting means comprises means for fixing to the housing and at least one fixing surface, said housing being provided with a front face against which the fixing surface is pressed.
[0020] Preferably, the travel limiting means comprises at least two fixing surfaces arranged on opposite faces of the travel limiting means.
[0021] According to a preferred variant, the front face and / or the fixing surface(s) extend(s) essentially in a plane which is orthogonal to the first axis of rotation and / or to the second axis of rotation.
[0022] According to a possible additional characteristic, the travel limiting means is capable of being fixed to the housing in at least two distinct fixing positions.
[0023] The invention also relates to a door or window type joinery comprising a frame, two openings, at least one of which is movable in translation and / or in rotation relative to the frame, an operating means and a locking system comprising a control member, a locking element such as a striker and a locking device such as a locking hook or such as a locking roller movable as a function of a rotation of the control member, said joinery further comprising a follower return device according to the invention.

[0038] As shown in the figures of the attached drawings, the present invention relates to a follower return device 20 for a locking system 10 of a door or window type joinery 0 as well as a door or window type joinery 0 provided with a locking system 10 provided with such a follower return device 20.
[0039] The follower return device 20 according to the present application is suitable for a locking system 10 comprising a control member 11, a locking element 14 such as a striker and a locking device 16 such as a locking hook or such as a locking roller movable as a function of a rotation of the control member 11. The follower return device 20 comprises a housing 30, a transmitting member 40 housed in said housing 30 and capable of pivoting about a first axis of rotation A1 and a receiving member 50 housed in said housing 30 and capable of receiving a first part of an operating means 12 of the joinery 0, said receiving member 50 being housed in said housing 30 so as to be capable of pivoting about a second axis of rotation A2,the follower return device 20 further comprising one or more gears 22 making it possible to transform the pivoting of the receiving member 50 around the second axis of rotation A2 into a pivoting of the transmitting member 40 around the first axis of rotation AL. The follower return device 20 further comprises a sheath 60 capable of receiving a second part of the operating means 12 and capable of pivoting around the second axis of rotation A2 and a travel limiting means 70 of the operating means and / or of the sheath 60 capable of limiting the pivoting travel around the second axis of rotation A2 of the operating means 12 and / or of the sheath 60 between a first end position of the pivoting travel and a second end position of the pivoting travel.
[0040] The operating means 12 may comprise an operating handle as well as an operating element capable of cooperating with the receiving member 50 of the follower return device 20. The first part of the operating means 12 and / or the second part of the operating means 12 may be arranged on the operating element. The operating element may have a polygonal section, preferably a square section. The operating element is often called an operating square.
[0041] The joinery 0 according to the present application comprises a frame 2, two openings 1, 1' of which at least one is movable in translation and / or in rotation relative to the frame 2, an operating means 12 and a locking system 10 comprising a control member 11, a locking element 14 such as a striker, a locking device 16 such as a locking hook or such as a locking roller movable as a function of a rotation of the control member 11, said joinery 0 further comprising a follower return device 20 according to the present application.
[0042] Each of the openings 1, 1' may comprise a frame 3 composed of several elements 4 such as an upright or a crosspiece of the frame 3.
[0043] An element 4 of the frame 3 among the elements 4 of the frame 3 of a first opening 1 among the two openings 1, 1' comprises a projecting element 5 projecting from the element 4 of the frame 3 of the first opening 1 and partially covering an element 4 of the frame 3 of a second opening 1' among the two openings 1, 1'.
[0044] The follower return device 20 makes it possible to center the installation of the operating means 12 by constituting a mechanism interposed between the locking system 10 and the operating means 12.
[0045] The gear(s) 22 make it possible to transform the rotation of the receiving member 50, engaged with the operating element of the operating means 12, around the second axis of rotation A2 into a rotational movement of similar direction and amplitude of the transmitting member 40, engaged with the control member 11 of the locking system 10, around the first axis of rotation AL. The gear(s) 22 may be arranged in the housing 30.
[0046] The follower return device 20 may be of symmetrical design to allow it to be mounted on joinery 0 having right-hand or left-hand fittings. The follower return device 20 makes it possible to transmit the force supplied by the operating means 12 to the locking system 10.
[0047] The angular difference between the first end position of the pivot stroke and the second end position of the pivot stroke may correspond to 90° or 180°, for example.
[0048] The travel limiting means 70 may be provided with an opening 71 in which the sheath 60 is housed.
[0049] According to the first exemplary embodiment and the second exemplary embodiment, the travel limiting means 70 may be in the form of a flange.
[0050] The travel limiting means 70 may be either fixed to the housing 30 or integrated into the housing 30. In the case where the travel limiting means 70 is integrated into the housing 30, the travel limiting means 70 may constitute a wall of the housing 30 and / or be integrated into the housing 30. According to the first exemplary embodiment, the travel limiting means 70 may be fixed to the housing 30. According to the second exemplary embodiment and the third exemplary embodiment, the travel limiting means 70 may be integrated into the housing 30.
[0051] The first axis of rotation A1 may preferably be arranged in parallel to the second axis of rotation A2 and / or be arranged so as to be non-aligned with the second axis of rotation A2.
[0052] The sheath 60 may, either, in accordance with the first exemplary embodiment and the second exemplary embodiment, comprise a protrusion 62 projecting in a direction orthogonal to the second axis of rotation A2 provided with a first stop surface 64, or, in accordance with the third exemplary embodiment, comprise a recess 61 in the shape of an arc of a circle delimited by two ends, a first stop surface 64 being formed at a first end among the ends of the recess 61.
[0053] The travel limiting means 70 may comprise a first stop surface 72, the first stop surface 64 coming to bear against the first stop surface 72 when the operating means 12 takes the first end-of-travel position.
[0054] The travel limiting means 70 may comprise a second stop surface 74 and the protrusion 62 may either be provided with a second stop surface 66 or a second stop surface 66 may be formed at a second end opposite the first end of the recess 61, the second stop surface 66 bearing against the second stop surface 74 when the operating means 12 takes the second end-of-travel position.
[0055] The first abutment surface 72 may extend in a plane that is parallel to the plane in which the second abutment surface 74 extends. Alternatively, the first abutment surface 72 may extend in a plane that is orthogonal to the plane in which the second abutment surface 74 extends.
[0056] The first stop surface 64 may extend in a plane that is parallel to the plane in which the second stop surface 66 extends. Alternatively, the first stop surface 64 may extend in a plane that is orthogonal to the plane in which the second stop surface 66 extends.
[0057] The travel limiting means 70 thus comprises reliefs, formed by the first stop surface 72 and / or the second stop surface 74 capable of angularly limiting the rotation of the sheath 60, itself equipped with corresponding reliefs, formed by the first stop surface 64 and / or the second stop surface 66, limiting the travel of the operating means 12 and / or of the receiving member 50 around the second axis of rotation.
[0058] The sheath 60 is itself driven by the operating means 12, for example, through hollow reliefs 68 interacting with the operating element equipping the operating means 12.
[0059] Thus, the operating means 12 is hindered in its rotational movement around the second axis of rotation by means of the sheath 60 and the stroke limitation means 70. Ideally, the angular limitation thus obtained is 90° or 180°, corresponding to the usual end-of-stroke positions of the operating means 12.
[0060] The travel limiting means 70 may comprise means for fixing to the housing 30 and at least one fixing surface 76, 78, said housing 30 being provided with a front face 32 against which the fixing surface 76, 78 is pressed. The fixing surface 76, 78 is pressed against the front face 32 of the housing 30 in the first exemplary embodiment and the second exemplary embodiment.
[0061] The means for fixing the travel limiting means 70 to the housing 30 can be produced in the form of holes 73 aligned with corresponding holes 33 provided in the housing 30, preferably in the front face 32 of the housing 30.
[0062] According to the third embodiment, the travel limiting means 70 takes the form of a wedge provided with a stop attached to the housing 30, projecting from the follower return 10, interacting with the sheath 60 through reliefs formed by the first stop surface 64 and / or the second stop surface 66. This stop can also be integrated into a wedge attached to the housing 30. According to the three embodiments, the travel limiting means 70 and the sheath 60 can be integrated on or attached to the follower return device 10.
[0063] The stroke limiting means 70 may be capable of being fixed to the housing 30 in at least two distinct fixing positions. According to the three exemplary embodiments, the stroke limiting means 70 may be transferred from a first fixing position among the distinct fixing positions to a second fixing position among the distinct fixing positions by means of a rotation about an axis which is parallel to the first axis of rotation A1 and / or to the second axis of rotation A2, for example a rotation of 180°.
[0064] The travel limiting means 70 may comprise at least two fixing surfaces 76, 78 arranged on opposite faces of the travel limiting means 70. The travel limiting means 70 according to the first exemplary embodiment comprises two fixing surfaces 76, 78. The travel limiting means 70 according to the second exemplary embodiment and the third exemplary embodiment comprises a single fixing surface 76.
[0065] The stroke limiting means 70 comprising two fixing surfaces 76, 78 can be transferred from a fixing position, in which the stroke limiting means 70 is fixed to the housing 30 by means of a first fixing surface among the two fixing surfaces 76, 78, to a fixing position, in which the stroke limiting means 70 is fixed to the housing 30 by means of a second fixing surface among the two fixing surfaces 76, 78, by a rotation of the stroke limiting means 70 about an axis which is perpendicular to the first axis of rotation A1 and / or to the second axis of rotation A2 and / or which is horizontal relative to the position of the joinery 0, rotation for example of 180°.
[0066] The travel limiting means 70 according to the first embodiment can further comprising a third stop surface 75 and / or a fourth stop surface 77. The first stop surface 72 and / or the second stop surface 74 may be arranged to interact with the first stop surface 64 and / or the second stop surface 66 to limit the travel of the operating means 12 when the travel limiting means 70 is fixed to the housing by means of the first fixing surface 76. The third stop surface 75 and / or the fourth stop surface 77 may be arranged to interact with the first stop surface 64 and / or the second stop surface 66 to limit the travel of the operating means 12 when the travel limiting means 70 is fixed to the housing by means of the second fixing surface 78.
[0067] The travel limiting means 70 according to the first embodiment can thus comprise a total of four distinct fixing positions: two fixing positions using the first fixing surface 76 among the two fixing surfaces 76, 78 as well as two fixing positions using the second fixing surface 78 among the two fixing surfaces 76, 78.
[0068] The two distinct fixing positions using the same fixing surface 76, 78 of the stroke limiting means 70 may differ in their angular position with respect to a rotation around an axis which is parallel to the first axis of rotation A1 and / or to the second axis of rotation A2, for example a rotation of 180°.
[0069] Thus, the travel limiting means 70 can interact with the stop surfaces 64, 66 of the sheath 60 via the first stop surface 72 and / or the second stop surface 74, when the travel limiting means 70 is fixed to the housing 30 via the first fixing surface 76 and interact with the stop surfaces 64, 66 of the sheath 60 via the third stop surface 75 and / or the fourth stop surface 77, when the travel limiting means 70 is fixed to the housing 30 via the second fixing surface 78.
[0070] Thus, the first stop surface 72 may extend in a plane that is parallel to the plane in which the second stop surface 74 extends to allow an angular difference of 180° between the first end position and the second end position when the stroke limiting means 70 is fixed to the housing 30 by means of the first fixing surface 76. Furthermore, the third stop surface 75 may extend in a plane that is orthogonal to the plane in which the fourth stop surface 77 extends to allow an angular difference of 90° between the first end position and the second end position when the stroke limiting means 70 is fixed to the housing 30 by means of the second fixing surface 78.
[0071] The advantages arising from the present invention are substantial. In particular, the follower return device 20 in accordance with the present application makes it possible to guarantee an end-of-travel positioning of the operating means 12, in the open or closed position of the locking system 10, perfectly aligned with the crosspiece of the joinery 0 which it equips.
