The invention also relates to a sliding leaf comprising such a espagnolette.

Sliding shutters are already known comprising a gear drive device assembled to an operating lever of the opening and adapted to define extreme positions of rotation of said operating stand. The extreme positions of rotation of the operating stand are generally defined so that the operating stand can be moved between a closed position in which the stand is oriented vertically and an open position arranged at an angle of less than 45 ° by relative to said closed position. Limiting the opening position of the maneuvering stand at an angle of less than 45 ° with respect to the vertical makes it easier to manipulate a sliding leaf when moving between an open position and a closed position of the sash by relative to an open position in which the operating stand is oriented at an angle equal to 90 ° relative to the vertical.

The extreme positions of movement of the input member and the output member of said mechanism allow to define extreme positions of rotation of the operating stand.

In addition, at least one bolt is assembled integral with said bolt-holder rod.

In a drive device according to the invention, the housing comprises all the necessary elements (mechanism disposed in said inner chamber of the housing) for manipulating a bolt rod from a driving square assembled to a jack stand to the bolt carrier of the cremone bolt and to define extreme positions of rotation of the leading square and said kickstand maneuvering.

Generally, said hollow profile of the opening is a longitudinal profile of the opening disposed vertically when the opening is mounted on the frame so as to define a song of the opening.

The hollow profile also has an opening arranged to be traversed by said leading square so that the leading square can be assembled to the housing of the drive device disposed in the hollow of the hollow profile and to the operating stand placed on an outer front face. hollow profile.

In addition, the inlet opening of the housing is intended to be disposed opposite the opening of the hollow section through which the leading square so that the latter reaches the input member of said mechanism.

Furthermore, the housing is not visible by a user because it is disposed in the hollow of the profile of the opening and not on a front face of this profile.

Placing the housing in the hollow profile improves the exterior aesthetics of the opening. In addition, the costs of such a housing is reduced because it is not visible so that its appearance does not require the use of expensive material that can have expensive aesthetic finishes.

In addition, advantageously, said outlet opening is at least substantially orthogonal to said inlet opening.

Thus, said inlet opening may be parallel to the outer end face of the hollow profile and the outlet opening may be parallel to the edge of the hollow profile.

In certain advantageous embodiments and according to the invention, the mechanism is a gear comprising at least two gears, a gear first gear, said input gear, forming said input member and a second gear, said output gear, forming said output member.

Furthermore, in some advantageous embodiments and according to the invention, the input member -in particular the input gear- is guided with respect to the housing in rotation with respect to a theoretical axis of rotation passing through said opening of Entrance.

Preferably, the inlet opening extends in a plane orthogonal to said theoretical axis of rotation of the input member.

In addition, the input member -in particular the input gear-comprises a housing, said receiving housing, extending along said theoretical axis of rotation of the input member.

Said reception housing of the input member is arranged to receive a first end of the driving square. A second end of the trailing square is intended to be assembled to a sidestand of the sliding leaf. In particular, said receiving housing and said driving square have conjugate shapes.

In addition, the receiving housing of the input member is disposed on an axis of rotation of the input member.

Preferably, said receiving housing has a non-circular cross section, in particular of square cross section. Nevertheless, nothing prevents to provide a housing of circular section if assembly means are provided between the input member and said square for rotatably coupling said input member to said square.

Advantageously, the casing comprises means for fixing the casing to a sliding door cremone headrest on which said bolt-holder rod is slidably mounted. In particular, the housing comprises threads for fixing the housing to said headrest. More particularly, screws through said headrest by lights of the headrest can be screwed into said threads. Thus, a mounting of the drive device on a sliding leaf is simple and fast. In Indeed, it is sufficient only to fix the housing to said headrest of the espagnolette and assemble the square leading to said mechanism disposed in the inner enclosure of the housing.

Said bolt rod comprises at least one lumen - in particular three adjacent lumens along a longitudinal axis of the bolt rod - receiving at least one tooth of the toothing of the output pinion to be able to be driven in translation when the output gear is rotated. The translation drive of said bolt-holder rod is carried out when a tooth received in a light of the bolt-holder rod exerts a force against a border of this light of said bolt-holder rod (when the output pinion is driven in rotation).

In particular, the bolt-holder rod can be driven in translation between a locking position in which each bolt is kept engaged in a striker of a frame on which is mounted the opening and an unlocking position in which each bolt is not in the grip of a waste of a frame.

Preferably, said input gear also comprises a through thread adapted to receive a screw, said holding screw, for maintaining said leading square in said housing of the input gear.

In order to mount the driving square after the housing is assembled to the headrest of the espagnolette, the housing has a suitable light so that a screwdriver can reach said retaining screw disposed in the tapping of the input gear. In addition, the bolt carrier and the headrest also each have a light opposite said housing light so that a screwdriver can reach the housing and said retaining screw.

Advantageously and according to the invention, the drive device is arranged to be placed in a hollow profile of the sliding leaf receiving said espagnolette. In particular, said housing has a rectangular parallelepipedal shape and has main faces of the housing having a width of less than 30 mm, more particularly less than 20 mm, in particular of the order of 16mm and side faces having a width less than 50mm, more particularly less than 40mm, in particular of the order of 30mm.

Said transmission is adapted to increase the transmission ratio between the input gear and the output gear. In other words, said transmission is adapted to allow, from a rotation on an angle α ₁ of the input gear, a rotation on an angle α ₂ of the output gear, α ₂ being greater than α ₁ . Increasing the transmission ratio between the input gear and the output gear increases the distance between the extreme translation positions of the bolt rod so that the bolt rod can reach a locking position and a position. unlocking.

In some embodiments, said transmission may be formed of a toothing of the input member-in particular the input gear- and a toothing of the output member-in particular the output gear-in gear with the teeth of the input member - in particular the input gear -. Said mechanism then comprises only an input member -in particular the input gear- and an output member -in particular the output gear-.

In some other embodiments, said transmission comprises at least one pinion coupling said input member to said output member. Thus, in some embodiments, said transmission comprises a plurality of gears. However, in some advantageous embodiments and according to the invention, said transmission comprises a single pinion, said intermediate gear, rotatably coupled to said input gear and said output gear.

Preferably, the pinion has an oblong shape having a first end engaged with the input gear and a second end engaged with the output pinion. The oblong shape of the intermediate gear makes it possible to have a sufficiently large distance between the two ends to modify a transmission ratio between the input gear and the output gear while being able to be contained entirely in said housing.

In addition, in certain advantageous embodiments and according to the invention, the stops of the driving device are formed in the inner enclosure so that the intermediate gear is in contact with these stops when it reaches its extreme positions of rotation. . Preferably the stops are formed by the wall of the housing. Nevertheless, nothing prevents the provision of studs as abutments reported on the wall of the housing in the inner enclosure of the housing.

Preferably, the output gear has a first series of teeth coupled to said transmission and a second series of teeth adapted to be engaged with said bolt carrier. More particularly, the dimensions of the output gear are adapted so that the first set of teeth is disposed in the inner enclosure of the housing and the second set of teeth at least partially passes through said housing outlet opening to be able to engage of said bolt carrier.

Thus, the output gear radius at said first set of teeth is smaller than the output gear radius at said second set of teeth. In particular, in certain embodiments and according to the invention, the output gear has a transmission ratio between said first set of teeth and said second set of teeth greater than 1.

In some embodiments and according to the invention, the radius of the output gear at said second set of teeth being greater than that at said first set of teeth, said intermediate gear comprises a groove arranged to allow the passage of said second set of teeth of the output gear. Thus, the intermediate gear comprises two parallel fingers each having a portion of said first set of teeth coupled with said output gear, the two fingers being spaced apart from each other so as to form said groove allowing the passage of said second series of teeth of the output gear.

Furthermore, the housing wall and the gears of said mechanism have conjugated assembly means. More particularly, these conjugated assembly means form a pivot connection between each pinion and the wall of the housing. These conjugated assembly means thus make it possible to define the axis of rotation of each pinion of said mechanism (in particular the input gear, the intermediate gear and the output gear).

In certain embodiments and according to the invention, said stops are arranged to limit a rotational stroke of said input gear on an angle less than or equal to 45 °, more particularly less than 30 °, more particularly of the order of 20 °.

Limiting the rotational stroke of the input gear also limits the rotational stroke of the operating stand. The driving device (said stops and said mechanism) is adapted so that the operating stand can be moved between a closed position in which the stand is oriented vertically and an open position arranged at an angle less than 45 °, more particularly of the order of 20 °, with respect to said closed position. Limiting the opening position of the maneuvering stand at an angle of less than 45 °, more particularly of the order of 20 °, relative to the vertical makes it easier to manipulate a sliding leaf when it is moved between a open position and a closed position of the opening.

In certain preferred embodiments and according to the invention, said mechanism has a transmission ratio between said input gear and said output gear greater than or equal to 2, in particular equal to 2 when the input gear can be driven into position. rotation at an angle of 45 ° and equal to 4.5 when the input gear can be rotated at an angle of 20 °.

Furthermore, without being limiting, it is advantageous in some embodiments to provide that said intermediate gear has a bearing arranged to come into contact with a bending elastic blade assembled to said housing wall in said inner enclosure.

The mechanical strength of the elastic blade when the latter is driven in flexion improves the comfort of handling of the stand by a user.

• a spring disposed in said housing and adapted to bias the pin into said locking position from said release position.

More particularly, the spring is placed between a bottom of the housing of the locking device and an end of said pin facing the bottom of the housing.

The pin is then in a release position when the spring is retracted when a pressure is exerted on said pin towards the bottom of the housing of the locking device (particularly when the section bearing the espagnolette of the opening is placed against the frame). The pin is then in a locking position when the spring is deployed when no pressure is exerted on said pin towards the bottom of the housing of the locking device (especially when the section bearing the espagnolette of the opening is not placed against the frame bearing each strike).

Thus, the locking device allows manipulation of the bolt rod only when the sliding leaf is in a closed position, that is to say when said hollow section of the leaf is placed against the frame.

The cylindrical portion 61 of revolution of the input pinion 58 also includes a through threaded thread 64 adapted to receive a screw, said screw 65 for holding, to maintain said square 32 leading into said housing.

So as to mount the square 32 leading after the housing 41 is assembled to the headrest 27 of the espagnolette 26, the housing 41 has a slot 66 adapted for a screwdriver to reach said retaining screw 65 disposed in the tapping 64 input pinion 58. In addition, the rod 28 bolt carrier and the headrest 27 also each has a light opposite said housing light 41 so that a screwdriver can reach the housing 41 and said screw 65 holding.

The input gear 58 also comprises an arm 67 projecting from said cylindrical portion 61 of revolution of the input gear 58 and the housing 59 for receiving the input gear 58. The arm 67 comprises a distal end having two teeth 68.

The driving device 40 comprises another pinion, referred to as the intermediate pinion 69. The intermediate pinion 69 is coupled to the input pinion 58. The intermediate pinion 69 and the housing 41 have conjugated joining means forming a pivot connection about an axis 70 of rotation of said intermediate pinion 69. More particularly, the axis 70 of rotation of the intermediate pinion 69 is orthogonal to the main faces 42 of the housing 41. In particular, the housing 41 comprises a pivot, said pivot 71 intermediate, extending in the inner chamber along said axis 70 rotation of said intermediate pinion 69 and the intermediate pinion 69 comprises a bore 72 into which is inserted said intermediate pivot 71 of the housing 41 so as to form said pivot connection.

Said intermediate pinion 69 has an oblong shape. In particular, the intermediate pinion 69 comprises two arms 73a, 73b extending from said bore 72 of the intermediate gear 69 in a direction opposite to each other. A first arm 73a of the intermediate pinion 69 is coupled to said arm 67 of the input pinion 58. In particular, the first arm 73a of the intermediate pinion 69 comprises a distal end comprising three teeth 74 between which are interposed the two teeth 68 of the input pinion 58. Thus, when the input gear 58 is rotated in one direction, the intermediate gear 69 is rotated in an opposite direction. More particularly, the transmission ratio between the input pinion 58 and the intermediate pinion 69 is greater than 1.

In addition, a second arm 73b of the intermediate pinion 69 is coupled to another pinion, called the output pinion 77, of the drive device 40. The intermediate pinion 69 thus forms a transmission between the input pinion 58 and the output pinion 77. In particular, the second arm of the intermediate pinion 69 comprises a distal end having two fingers, said upper finger 75a and lower finger 75b, parallel to each other and spaced from each other by a groove 96 Each finger 75a, 75b of the distal end of the second arm of the intermediate pinion 69 has three teeth 76a, 76b.

The intermediate pinion 69 is held axially by the wall portions of the housing 41 forming said main faces 42.

The output gear 77 and the housing 41 have conjugated assembly means forming pivot connection about an axis 78 of rotation of said output gear 77, the axis 78 of rotation of the output gear 77 being orthogonal to the main faces 42 In particular, the output pinion 77 comprises a main toothed portion 79 and two pivots, said output pivots 80, extending along the axis 78 of rotation of the output pinion 77 projecting from said main portion 79. toothed in a direction opposite to each other. In addition, each main face of the housing 41 comprises a hole 81a, 81b forming a receiving bearing of a respective output pivot 80.

The main toothed portion of the output pinion 77 comprises two series 82, 83 of teeth. A first series 82 of teeth is coupled to the second arm of said intermediate pinion 69 and a second series 83 of teeth is coupled to the rod 28 bolt carrier. The distance between the second series 83 of teeth and the axis 78 of rotation of the output gear 77 (that is to say the radius of the second series 83 of teeth) is greater than the distance between the first series 82 of teeth and the axis 78 of rotation of the output pinion 77 (that is to say the radius of the first series 82 of teeth). In particular, the transmission ratio between the first series 82 of teeth and the second series 83 of teeth of the output gear 77 is greater than 1. Thus, the transmission ratio between said input gear 58 and said output gear 77 is greater than or equal to 2.

The output gear 77 is held axially by the wall portions of the housing 41 forming said main faces 42.

The first series 82 of teeth comprises four teeth 84 and is disposed on either side of the second series of teeth. In particular, two teeth, called upper teeth 84a, of the first series 82 of teeth are arranged on a first side of the second series 83 of teeth and are engaged with the teeth 76a of the upper finger 75a of the second arm 73b of the pinion 69 intermediate. Two other teeth, called lower teeth, are arranged on a second side of the second series 83 of teeth opposite to the first side. These two lower teeth are engaged with the teeth 76b of the lower finger 75b of the second arm 73b of the intermediate pinion 69. Thus, when the intermediate gear 69 is rotated in one direction, the output gear 77 is rotated in an opposite direction. The output gear 77 is rotated in the same direction as that of the input gear 58.

Said second series 83 of teeth comprises three teeth 85a, 85b, 85c. In any rotational position of the output gear 77, the outlet opening 49 of the housing 41 is traversed by at least one tooth 85a, 85b, 85c of said second series 83 of teeth so that said second series 83 of teeth is taken with the rod 28 bolt carrier. In addition, the groove 96 of the second arm 73b of the intermediate pinion 69 allows the rotation of the output pinion 77 by allowing the passage of at least a portion of the teeth 85a, 85b, 85c of the second series 83 of teeth of the pinion 77 of FIG. exit.

The rod 28 bolt carrier comprises three adjacent lights 86a, 86b, 86c for coupling the rod 28 bolt holder to pinion 77 output. A first light, called lower light 86a, has a bearing 87a, defined by a border of an upper longitudinal end of the lower light 86a, against which a first tooth 85a of said second set of teeth 83 of the output gear 77 can be disposed. This bearing 87a allows the output gear 77 to drive the rod 28 upwards from a lower position of the rod 28 bolt holder when the stand 23 is rotated in a clockwise direction so as to place the bolt 29 in a locking position.

A second light, called central light 86b, of the rod 28 bolt holder has two bearing surfaces 87b, 87c, defined by the edges of the central light 86b at the longitudinal ends of the central light 86b, against which a tooth 85b central said second 83 series of teeth of the output gear 77 can be arranged. These bearing surfaces 87b, 87c allow the output gear 77 to drive the bolt 28 rod up or down from a central position of the rod 28 bolt holder, when the stand 23 is rotated in a direction of clockwise rotation (to move the rod 28 bolt holder upwards) or in a direction of trigonometric rotation (to move the rod 28 bolt holder downwards).

A third light, called upper light 86c, of the rod 28 bolt holder has a bearing 87d, defined by a border of a lower longitudinal end of the upper lumen 86c, against which a third tooth 85c of said second series 83 teeth output pinion 77 can be arranged. This bearing 87d allows the output gear 77 to drive the rod 28 downwards from an upper position of the rod 28 bolt holder when the stand 23 is turned in a direction of trigonometric rotation so as to place the bolt 29 in an unlocked position.

Furthermore, the drive device 40 comprises a locking device 88 integrated in the housing 41. This locking device 88 comprises a housing 89 and a pin 90 assembled sliding at least partially in this housing 89. The pin 90 can be moved between a locking position in which the pin 90 is adapted to be able to pass through a light 91 of the headrest 27 so as to prevent the bolt 28 from sliding in the headrest 27 and a release position in which the pin 90 no longer passes through said light 91 of headrest 27 so as to allow sliding of the rod 28 bolt carrier. In addition the pin also passes through the light 86c of the rod 28 bolt holder to access the light 91 of the headrest 27.

The locking device also comprises a spring 92 disposed in said housing 89 between a bottom of the housing 89 of the locking device and an end of said pin 90 facing the bottom of the housing 89. The spring 92 is adapted to return the pin 90 in said blocking position from said release position.

The pin 90 is in a release position when the spring 92 is retracted when a pressure is exerted on said pin 90 towards the bottom of the housing 89 of the locking device (particularly when the section 20 carrying the espagnolette 26 of the opening is placed against the frame) for retracting the spring 92. The pin 90 is then in a locking position when the spring 92 is deployed when no pressure is exerted on said pin 90 towards the bottom of the housing 89 of the locking device (in particular when the section 20 bearing the espagnolette 26 of the opening is not placed against the frame bearing the latches).

Thus, the locking device allows movement of the rod 28 bolt holder only when the sliding leaf is in a closed position, that is to say when said hollow section of the opening is placed against the frame.

Furthermore, the drive device 40 comprises a resilient flexion blade 93 disposed in the interior chamber 47 of the housing 41 and said intermediate gear 69 has a bearing surface 94 arranged to come into contact with this blade 93.

The mechanical strength of the blade 93 when the latter is flexed by said bearing surface 94 of the intermediate gear 69 makes it possible to improve the handling comfort of the stand 23 by a user.

Furthermore, the driving device 40 comprises stops 95a, 95b defined in the inner enclosure 47 of the housing 41 and being adapted to define extreme positions of the gears 58, 69, 77 of the mechanism 57.

The stops 95a, 95b are formed by the wall 46 of the housing 41, in particular by the wall portions defining the lateral faces 45 of the housing 41. More particularly, the stops 95a, 95b are arranged so that the intermediate pinion 69 can abut against they define its extreme positions of rotation. The extreme positions of rotation of the intermediate gear 69 make it possible to define the extreme positions of rotation of the input gear 58 and the output gear 77. In addition, the extreme rotational positions of the input gear 58 make it possible to define extreme positions of rotation of the stand 23 of operation.

More particularly, the stops 95a, 95b of the driving device 40 are arranged so that the stand 23 can be moved between a closed position in which the stand 23 is oriented vertically and an open position arranged at a lower angle at 45 °, more particularly of the order of 20 °, with respect to said closed position. Limiting the opening position of the stand 23 at an angle of less than 45 °, more particularly of the order of 20 °, relative to the vertical makes it easier to manipulate a sliding leaf when moving it between an open position and a closed position of the opening.

In particular, the transmission ratio between said input gear 58 and said output gear 77 is chosen to be 2 when the input gear can be rotated at an angle of 45 ° and equal to 4.5. when the input gear can be rotated at an angle of 20 °

The invention can be the subject of many variants and applications other than those described above. In particular, it goes without saying that except otherwise, the various structural and functional features of each of the embodiments described above should not be considered as combined and / or closely and / or inextricably linked to each other, but rather as simple juxtapositions. In addition, the structural and / or functional characteristics of the various embodiments described above may be wholly or partly the subject of any different juxtaposition or any different combination. For example, the stops 95a, 95b defining the extreme positions of rotation of the pinions 58, 69, 77 of the mechanism 57 may be formed of studs arranged in the inner enclosure 47 of the casing 41. In addition, the mechanism 57 may comprise several pinions 69 intermediate between the input pinion 58 and the output pinion 77. Alternatively, the input gear 58 can be directly coupled to the output gear 77.

A driving device 40 according to the invention can be used to manipulate a rod 28 bolt-holder espagnolette 26 sliding leaf.
