Description

The invention relates to a locking / unlocking device for window sash, door or the like, and an opening equipped with at least one such locking / unlocking device. . The invention is particularly suitable for sliding sashes, but can be installed on other types of sashes, for example hinged opening doors, swing, etc.. The openings often include a frame formed of hollow profiles (having thin walls), and are equipped with a locking fitting embedded in a mounting slot, formed through a front wall (that is to say of large size). surface) of the opening. These doors are generally provided, for their locking / unlocking, as well as to allow opening and closing maneuvers of the opening, a handle protruding from the front wall of the opening or, in the case of sliding sashes, a recessed handle cup type handle. FR 2 877 979 discloses a locking / unlocking device for hollow sliding leaf having a rotary cremone-type operating handle for moving a drive member, and transmission means mechanically connecting each drive member to at least one rod control. This handle makes it possible to lock and unlock the opening by a rotation of the handle then requires, for opening and closing maneuvers of the opening, to pull or push on the handle in a direction parallel to the direction of the door. opening / closing of the opening. This locking / unlocking device requires to provide significant efforts for the opening and closing maneuvers of the opening and is not adapted to the operation of the opening, mainly in terms of ergonomics. Traditionally, the sliding sashes are provided with hardware comprising a technical housing, comprising the components of the locking mechanism, and a finishing facing, covering the mounting light and masking the technical housing. This technical box comprises a control slider forming a cup handle type handle, that is to say comprising a notch allowing the passage of a user's fingers for opening and closing maneuvers. In addition to a limited aesthetic, this handle is also impractical to use, only the fingertips can be inserted into the notch formed. The opening and closing maneuvers of the opening, as well as the longitudinal actuation in translation of the control slide, require indeed to provide significant efforts only with the fingertips.

On swing wings, the locking / unlocking control handles are often rotatably mounted about an axis orthogonal to the main plane of the leaf. It is therefore, for a user to perform two separate movements to lock / unlock and open or close such an opening. Thus, to open such an opening, a user must first turn the handle to unlock the door, then pull or push this handle orthogonally to the opening to open by rotating it around its axis. Also, other devices have been proposed to improve the ergonomics of locking / unlocking sliding doors. For example WO 2008/033702 is known, which makes it possible to store energy intended for later locking of the device, in particular at the time of the complete closure of the door. This energy is stored in two springs during the unlocking of the device. A locking member blocks the springs as the opening is open. The contact between this locking member and a suitable wall intervening when the opening is closed, allows the springs to bring bolts in the locking position. However, such devices are not suitable for all types of sliding sashes since they must be mounted on the edge of the sash. They also have other significant disadvantages due to the wear of the locking member often made with small fragile parts.

The invention aims to overcome these disadvantages by providing a locking / unlocking device for an opening, combining aesthetics and ergonomics, allowing in particular to perform the operations of locking / unlocking and opening / closing of the opening, a only gesture, that is to say continuously, and without requiring special effort or several separate movements from a user.

It aims in particular a locking / unlocking device for automatically locking the door when fully closed. It also aims to provide a locking / unlocking device whose mechanism has a good behavior over time, and which is suitable for repeated opening and closing maneuvers. In addition, it aims to provide a device to ensure high security in terms of use and control of locked and unlocked states of the opening. It also aims to provide such a device allowing the use of any type of technical housing comprising the components of the locking mechanism and intended to equip an opening. It aims in particular to provide a device that does not present fragility to wear by shocks or the sudden breakage of locking parts during handling by a user. The invention also aims at providing such a device which can be mounted on metallic openings, in particular aluminum alloy, as well as on plastics openings, in particular made of PVC, wood, or others, including assemblies of these materials. It also aims to provide a locking / unlocking device for opening allowing to vary the aesthetics at will, at the time of the finishing steps of the building. To do this, the invention relates to a locking / unlocking device for an opening comprising: - an actuator movable relative to the opening 30 between at least one open position allowing the opening of the opening and at least a closing position allowing the closure of the opening, - a locking mechanism adapted to be fixed to the opening, and comprising: o at least one bolt, o wall detection means, activated when the locking mechanism is close to a wall with respect to which it can be locked via at least one bolt moved in locked position, o an actuator comprising at least one member, said accumulator member adapted to store mechanical energy and for restoring it, said actuator being able to drive at least partially at least one bolt from the unlocked position to the locked position by mechanical energy return stored by the accumulator member, characterized in that said locking mechanism comprises transmission means: - interposed between the operating member and at least one bolt, - adapted to move each bolt between a locked position and an unlocked position, - Having a mechanical connection with said accumulator member, adapted so that: o the displacement of the actuating member on at least one stroke portion from an open position to a successive closed position of the actuating member refilling in energy the accumulator member, o the displacement provided by said accumulator member returning stored energy is transmitted to each bolt to move between an unlocked position and a locked position. Advantageously and according to the invention, said operating member is movable between at least two positions: in at least one position, called the open position, the operating member is in a position which facilitates the opening of the opening by a user: in at least one other position, said closed position, different from at least one open position, the operating member is in a position that facilitates the closing of the door by a user. Nothing prevents that the operating member of a device according to the invention can be moved between several closed positions and several open positions in order to add opening / closing functions (for example 'between-opening) of an opening equipped with such a device. Advantageously and according to the invention, the movement of the actuating member from a closed position to an open position ensures the unlocking and allows the drive to open the opening. Similarly, the movement of the operating member from an open position to a closed position allows at least the closing of the opening. Thus, when a user makes an opening movement of an opening equipped with a device according to the invention, the operating member is moved from a closed position to an open position by unlocking the mechanism of locking. When a user closes such an opening, it acts on the operating member and moves it from an open position to a closed position by storing in the accumulator member a portion of the mechanical energy imparted by the user on the actuator. In other words, when closing the opening, the operating member does not remain in the open position until the complete closure of the opening, but instead it is moved from an open position to a closed position, either at the beginning of the closing movement of the sash, or during the closing movement of the sash. The mobility of the operating member provides a certain continuity of movement, for a user, between the unlocking and opening of the opening on the one hand, and the closing and locking of the opening on the other hand. Thus, advantageously and according to the invention, an operating member is mounted such that its movement between an open position and a closed position involves a movement of the user in continuity with the movement necessary for opening / closing of the opening. An operating member according to the invention can be mounted movably relative to the opening according to different embodiments, depending on the type of opening. In particular it can be rotatably mounted about an axis according to a pivot connection, or it can be mounted in translation in a slideway. For example, for an operating member rotatably mounted about a pivot connection, the rotation of the operating member from a closed position to an open position is around an axis and in a direction such that this rotation is accompanied by the opening of the opening. Similarly, in this configuration, the rotation of the actuating member from an open position to a closed position is in a direction such that it accompanies the closing of the opening. Thus, in the particular case of a swing leaf, the rotation of the operating member about an axis parallel to the axis about which the opening is flapping is advantageous. For a leaf opening intended to be opened by a user by pulling the leaf towards him, the unlocking of the opening is done when the actuating member moves from a closed position in which it is folded towards the opening, to an open position deployed more protruding from the opening. This configuration thus ensures a continuity of the opening and closing movement. Thus, the user pulls the operating member towards him to unlock the door, then, the operating member being in the open position (the most protruding), the user pulls the door towards him. The user actually makes only one movement: shoot. Similarly, in the case of an actuator mounted in translation in a slideway, the translation of the actuating member from a closed position to an open position is in a direction and a direction such that they accompany the opening of the opening. In this configuration, the translation of the operating member from an open position to a closed position is in a direction and a direction as they accompany the closure of the opening.

Thus, on a sliding type door, the translation of the actuating member along a slide direction parallel to the sliding of the opening ensures this continuity of movement: for the opening of the opening, the body operating mechanism slides from a closed position to an open position in the same direction as the opening direction of the sash (in the opposite direction for closing and locking the sash). Finally nothing prevents to combine a sliding actuator to a swing leaf or a pivoting actuator member to a sliding leaf.

Thus, for example in the case of a sliding leaf and a pivoting actuating member, the actuating member is advantageously pivotally mounted about an axis parallel to the main surface of the leaf and orthogonal to the direction of movement. sliding of the opening. Parallel and orthogonal include both strictly parallel (respectively orthogonal) than substantially or generally parallel (respectively orthogonal). In this embodiment, the actuator advantageously has at least one open position in which it is folded towards the opening, and at least one closed position in which it is deployed projecting relative to the opening . Thus the opening movement of the door by a user consists of a displacement of the actuating member from a closed position to an open position in a direction and a direction similar to the sliding movement in opening of the opening. Similarly, during closure, the movement made by a user to move the sliding leaf to a closed position also moves the actuating member from an open position to a closed position. In all cases, an operating member according to the invention is adapted to be mounted on an opening so that the movement of the actuating member from a closed position to an open position ensures the unlocking and causes the opening opening in a continuous movement for a user and that the movement of the actuating member from an open position to a closed position ensures the locking 2968335 s and causes the closing of the opening in a continuous movement for a user. Furthermore, since the operating member has at least two distinct positions respectively corresponding to an open position and a closed position, the visibility of the position of this actuating member provides an effective means of controlling the state of operation. locking (or unlocking) the opening. Indeed, the locked state and the unlocked state correspond to two visually different positions of the operating handle, identifiable by a user, even from a distance, and when the user is not in front of 10 the opening. In addition, the unlocking and locking maneuvers are facilitated: the user exerts a force of unlocking and opening by a natural ergonomic movement of his arm while in some systems of the state of the art, he had to unlock the opening with a finger, by a little ergonomic movement. The displacement of the operating member makes it possible to control the locking or unlocking of the sash and, in the same way, continuously, closing or opening the sash, intuitively and ergonomically, without require significant effort and / or complex from the user of the opening. Thus, such a device does not require a user to produce two distinct movements for unlocking and opening (respectively closing and locking) of an opening equipped with a device according to the invention. Bolts of different types and numbers may be selected in accordance with the invention. In addition they can be lateral and lock a side face of the opening on the doorframe and / or they can be greater (s) and / or lower (s) and lock the faces (respectively upper and lower) of the opening on the frame in which the opening is closed, as in a lock type "cremone". Said wall detection means according to the invention can be made according to several embodiments. For example, one can choose a mechanical system in which a mechanical probe comes into contact with the door frame on which the door closes. Other mechanical means of equivalent function can be used according to the invention. Moreover, nothing prevents the realization of said wall detection means with optical and / or electronic components, or according to other technological solutions considered advantageous. Said wall detection means according to the invention remain activated as long as the opening is in the immediate vicinity of its closed position. In particular, such wall detection means are activated as soon as and as long as the bolt (s) can be locked on a latch (s) of the cooperating casing (s). with the said bolt (s). In addition, a locking mechanism according to the invention comprises an actuator. Such an actuator makes it easier to lock the opening, in particular by storing mechanical energy prior to the total closing of the opening. Such an actuator helps to lock the opening when it reaches its closed position near the doorframe. In particular, an actuator according to the invention is reset (or recharged in energy) during a movement of the user prior to the complete closure of the opening. In particular, such an actuator is automatically reloaded by the sole force exerted by the user on the operating member during a closing maneuver. An actuator according to the invention is functionally (in particular mechanically) connected to the locking bolts via said transmission means, in order to be able to move (or at least participate in the movement of) at least one locking bolt. an unlocked position at a locked position. Nothing prevents the actuator partially participates in locking the bolt (s). However, in an advantageous embodiment, an actuator according to the invention is arranged to store and restore a sufficient amount of energy to lock alone and completely all 30 bolts of the locking mechanism. An actuator according to the invention comprises at least one member, said accumulator member, capable of storing and returning mechanical energy. That is, an accumulator member according to the invention can receive mechanical energy and transform it for storage purposes in another form for retransforming and rendering it in mechanical form. An accumulator member according to the invention can be made in different ways: it can, for example, include a spring, magnets, a pneumatic cylinder, etc. Thus, the energy is not necessarily stored in mechanical form. In addition, an operating member according to the invention is advantageously mechanically connected to said actuator in order to recharge the accumulator member during a closing movement, and by this single movement. Advantageously, between an open position and a closed position, at least a portion of the movement travel of the operating member recharges the accumulator member energy. The work provided by a user during the movement of the actuator on this portion of stroke is partially stored as potential energy in the accumulator member. In particular the recharging of the accumulator member by the operating member is automatic and spontaneously results from the movement of the actuating member on the stroke portion provided for reloading the accumulator member. A displacement portion of movement of the operating member is defined as a portion of the possible movement of the actuating member between two distinct positions. Moreover, it is possible to equip devices according to the invention with locking elements of the control rod (or bolts) in the unlocked position. This blocking makes it easier to close the door when approaching the wall (door jamb) on which the door is closed and on which the locking mechanism can be locked. However, when the locking and unlocking of the control rod depends directly on the position of the control handle, and the locking element blocks the bolt (s) in the unlocked position, at least part of the forces exerted by a user on the handle to close the opening are reported on the locking element. The invention does not have this disadvantage, thanks to the actuator which makes it possible to uncouple the movement of the operating member (from an open position to a closed position) of the locking mechanism. Thus, the accumulator member accumulates the displacement energy of the operating member which is then in the ideal position for the closing maneuver, and the forces due to the push of the user to close the door are not or little reported on the blocking parts: only the energy stored by the accumulator member is exerted on these locking parts, and only during the closing time of the opening. Indeed, thanks to a device according to the invention, when closing an opening, the force exerted by a user to close said opening 15 does not tend to lock the locking / unlocking device and has the advantage of avoid: - moving the locking mechanism in a locking position, while the opening is still open (during the closing operation), which could lead to a mechanical shock between the bolt (s) of the locking mechanism and the doorframe, and - wear, at each closing maneuver, a locking element of the control rod and / or bolt (s), which remains active as the opening has not reached its closed position, said locking member being subjected to the effort exerted by a user to close the opening. Wear is all the more rapid as such locking elements are often small and fragile. A device according to the invention thus makes it possible to avoid the sudden breaking of fragile parts, and in particular of the locking pieces, but also their mechanical wear over time. In addition, storing energy in the accumulator member by a movement of the actuating member between an open position and a closed position has the advantage of not storing this energy for a long time. Indeed, instead of reloading the accumulator member upon unlocking of the opening, the invention allows to reload only when closing the opening. So that during the entire period during which the opening remains open, the accumulator member is discharged and does not exert pressure on potentially fragile parts or subject to creep. Advantageously and according to the invention, in a device according to the invention, said locking mechanism comprises locking means adapted to lock at least one bolt in the unlocked position when said wall detection means are inactivated.

Advantageously, said locking means are adapted to lock all the bolts in the unlocked position as long as the wall detection means are not activated, that is to say as long as the opening is at least partially open. The locking means can lock the bolt (s) in the unlocked position in a direct way, that is to say they block the bolt (s) him (them) themselves (s), or indirectly, that is to say they block the transmission means, for example a control slider, a control rod, or any other part of the locking mechanism. Advantageously, in a device according to the invention, the locking means are in the locking position as long as the opening is open and in the unlocking position as long as the door is closed. In particular, such locking means pass from an unlocking position to a locking position during unlocking of a device according to the invention. Locking the bolt (s) in the unlocked position as long as the door is open has the advantage of avoiding an impact when closing the door between the bolt (s) in the locked position and the jamb. Thus the risks of sudden rupture and / or wear of a part, and in particular of a part of the locking means, are reduced in a device according to the invention. Furthermore, the locking of the bolt (s) in the unlocked position keeps the energy stored in the actuator as the opening is not closed. Indeed, the (s) bolt (s) being locked (s) in unlocked position, the transmission chain between the actuator and the (s) bolt (s) is also blocked and the actuator is not able to restore the energy for locking bolts until the blocking means are not released, that is to say, as the wall detection means are not activated.

Such locking means can be made in different ways. For example, they advantageously comprise a part of the family of stoppers such as a pin, a key, etc ... In addition, advantageously and according to the invention, said actuator is mechanically connected to said locking mechanism, so to be able to charge said accumulator member during the movement of the actuating member from an open position to a closed position. Thus the operating member serves to unlock and open the opening during an opening movement performed by a user; and it serves for closing the door and for storing a necessary energy for its subsequent locking during a closing movement. Unlike other systems, the energy for locking being stored prior to the complete closure of the opening, the operating member can be moved from an open position to a closed position before the opening is completely closed. Indeed in such a device, it is not necessary to keep the operating member in the open position until the end of the closing movement of the opening to be able to lock the opening on the jamb by the displacement the actuating member from an open position to a closed position. This has the effect of facilitating the closing of the opening. Indeed, the closing position of the operating member is more suitable for closing the opening. By storing energy prior to the complete closure of the opening, such a device allows to uncouple the closed position of the operating member of the lock of the opening. Thus during a closing movement of an opening equipped with a device according to the invention, firstly the operating member is moved from an open position to a closed position by charging the accumulator member with energy. ; secondly the opening closes; thirdly, when the opening is closed on the doorframe, the wall detection means are activated, the locking means are deactivated (that is to say, they no longer block the bolts in the unlocked position); fourthly, the released actuator locks the bolts using the energy stored by the accumulator member. Thus, the opening and closing cycle of an opening through a device according to the invention is broken down, in the order, as follows. For opening: - a. the opening is in the closed position, the operating member is in a closed position, the locking mechanism is locked (the bolts are in the locked position), the locking means are not in the locked position (inactivated), and the wall detection means are activated, - b. the operating member is manipulated and moved in the opening direction of the opening by driving the locking mechanism to an unlocked position of each bolt, then the locking means pass to a locking position of each bolt in unlocked position, - c. the opening is open, the operating member is in an open position, the locking mechanism is unlocked (each bolt is in the unlocked position), the locking means are in a locked position (activated), the wall detection means are inactivated. For closing: - d. the operating member is manipulated and moved in the closing direction of the opening without driving the locking mechanism, and the storage member stores energy, e. the operating member is in a closed position, the opening moves in the closing direction, the bolts are in the unlocked position and the accumulator member is loaded, the locking means are activated (bolt (s) blocked ( s)) and the inactivated wall detection means 30 - f. the opening reaches the doorframe, the wall detection means are activated, the locking means pass to the unlocking position (inactivated), the actuator returns the stored energy to the locking mechanism and each bolt is locked. Moreover, many embodiments of an accumulator member according to the invention can be envisaged. For example, the accumulator member can accumulate energy and conserve stored energy regardless of the subsequent movement of the operating member (the actuator is reset). Alternatively, advantageously and according to the invention, the opening being open, said accumulator member is mechanically connected to the operating member via said transmission means, so that the accumulator member tends to return the operating member to a opening position. Also, the amount of energy stored by the accumulator member can be directly dependent on the position of the operating member. Thus, if the actuator is released before the end of the closing of the opening, that is to say, as the opening remains open and without the stored energy is used for locking the bolts , this energy can be immediately spent to make a return of the operating member in its open position (effect of a single spring) when the user releases the operating member. This second embodiment has the advantage of maintaining the relationship between the opening position of the operating member and opening (unlocked) of the door, which allows a remote user, to know if the door is locked or no. Indeed, if, in step e, the operating member is released, the actuator releases the stored energy to return the operating member in the open position.

The accumulator member thus provides a dual function: storing energy for locking the bolts at the end of closing the opening, and maintains (or return) the operating member in the open position as long as the opening is open. In addition, advantageously and according to the invention, said accumulator member comprises at least one spring adapted to store and restore mechanical energy by elastic deformation.

A spring has the advantage of being simple and inexpensive. It makes it possible to fully realize all the functions expected of an accumulator member in the context of a device according to the invention: it can store mechanical energy in elastic form, and then restore it in mechanical form. Different types of springs can be envisaged according to several embodiments of the invention: cylindrical spring, conical spring, flat spring, coil spring, scroll spring, or other. In addition, advantageously and according to the invention, said wall detection means comprise at least one mechanical probe movable between a rest position in which it protrudes with respect to the locking mechanism and a wall detection position in which it has entered the locking mechanism by contact with a wall. When the detection means are activated, the probe is at least partially retracted into the locking mechanism. Thus, when the opening passes from a closed position to an open position, the probe passes from a position in which said wall detection means are activated, to a rest position in which it protrudes with respect to the mechanism locking. On the contrary, when closing the opening on the doorframe, the protruding probe is pushed by the contact with the doorframe towards the inside of the locking mechanism, which has the effect of activating the wall detection means . Thus, advantageously, such a probe is maintained by default in the rest position, for example by a spring. It only goes into the position of detection of walls when a force is applied to it tending to get it into the locking mechanism, that is to say compressing the spring (non-restrictive embodiment example). The mechanical probe is not the only means that can be used as a wall detection means. Other mechanical systems, or optical, magnetic, etc. can also advantageously be chosen in the knowledge of their respective advantages.

Furthermore, advantageously and according to the invention, said transmission means comprise a central pusher adapted to be driven in displacement between a locking position corresponding to the locked position of at least one bolt and an unlocking position 5 corresponding to the unlocked position of at least one bolt. A central pusher according to the invention can take various forms, and for example it can be adapted to be able to drive a control slide between a locking position and an unlocking position. The central pusher may also be adapted to cooperate with a barrel of the locking mechanism, so as to drive each bolt moving between a locked position and an unlocked position. Advantageously and according to the invention, said transmission means comprise at least one control member of each bolt between a locked position and an unlocked position, adapted to be displaced by said central pusher between a locking position of each bolt and a latch. unlock position of each bolt. The control member is a part of the transmission means which forms the interface between the locking mechanism which is mounted in the opening, and the assembly integral with the operating member which is mounted on the outer part of the housing. opening. Different control members may be envisaged for various embodiments of the invention, among which, for example, a control slider, or a gun. In addition, advantageously and according to the invention, said actuating member 25 is movable about an axis according to a pivot connection, in particular about an axis at least substantially parallel to the opening and at least substantially orthogonal to a trajectory d opening of the opening. In the case of a swing leaf, such a maneuvering member may be pivotally mounted in the same direction of flap as the opening, or in a direction of flapping in opposition to that of the opening. In the case of a swing leaf, a close position close to the opening and an open position further from the opening allows for a device according to the invention in which the unlocking and opening of on the one hand, and the closing and locking on the other hand are in a continuous respective movement. In the case of a sliding leaf, the opening and closing positions depend on the direction of the beat of the pivot link. The closing and opening positions of the operating member must therefore be chosen in such a way that the pivoting of the actuating member occurs naturally during a single movement on the part of a user. Thus, for example, the user only pulls (or push) in one and the same direction to unlock (pivoting of the operating member around its pivot connection from a closed position to an open position) then open the opening. Similarly, to close and then lock the door, the user only pushes (respectively pull) in one and the same direction. The pivot connection and the opening and closing positions of the operating member are adapted for each leaf. Thus the axis of the pivot connection is advantageously orthogonal to the path of the opening to facilitate the unlocking and then the opening on the one hand and the closure and then the locking on the other hand respectively by a single and continuous movement of the door. 'user. In particular, the opening or closing role of each position is chosen according to the use of the opening: as the user must pull or push the opening to open (respectively to close). Advantageously and according to the invention, said transmission means comprise at least two cam rings. The cam rings make it possible to transform the rotational displacements of the operating member into translational movement of the central pusher. Advantageously and according to the invention, at least one ring is arranged to be driven in displacement between a charging position corresponding to a first energy charging state of the accumulator member, and a rest position corresponding to a second state. charging energy to the accumulator member, the amount of energy stored by the accumulator member being, in said second state of loading, less than the amount of energy stored by the accumulator member in said first state of loading. At least one cam ring makes it possible, by a forced translation movement, to store energy in the accumulator member. In particular the ring is moved between two positions when the operating member is itself moved between an open position and a closed position. The two positions of the ring correspond to two different levels of energy stored by the accumulator member.

In addition, advantageously and according to the invention, said transmission means comprise a transmission shaft adapted to receive said central pusher and said camming rings. Advantageously and according to the invention, said transmission shaft has splines parallel to each other and continuous along the longitudinal axis of said shaft. A transmission shaft according to the invention has a generally cylindrical shape of revolution, on which the grooves and other reliefs necessary for mounting and interaction of the transmission shaft in operation with other parts, are visible. Advantageously and according to the invention, said cam rings are integral in rotation with the transmission shaft and free in translation, parallel to the axis of said pivot connection of the handle, along the splines of the transmission shaft. For this purpose, the cam rings have flutes complementary to said parallel flutes of said transmission shaft. The central pusher is freely mounted in translation along the transmission shaft. Advantageously and according to the invention, the central pusher is adapted to form cam with two cam rings.

Thus, the forced rotation (by the displacement of the actuating member between a closed position and an open position, for example) of the rings along the transmission shaft has the effect of driving the central pusher in translation. along the camshaft by means of cams of at least one ring on the central pusher. Likewise, the forced rotation of the rings along the transmission shaft has the effect of compressing at least one spring (of the accumulator member) by the effect of cams of at least one ring on the central pusher, the central pusher being locked in the unlocking position via the transmission means blocked by the locking means when the door is open. In addition, advantageously and according to the invention, said central pusher comprises a connecting member adapted to be introduced into the opening and to cooperate with said control member of each bolt.

The connecting member is chosen to cooperate with the control member of the locking mechanism. Furthermore, advantageously and according to the invention, said connecting member of said central pusher is adapted to be able to drive a control slider between a locking position and an unlocking position. When the control member is a control slider, the connecting member of the central pusher has a shape complementary to the slider to be able to drive it in displacement. Similarly, advantageously and according to the invention, said connecting member of said central pusher is adapted to cooperate with a barrel so as to drive each control member in displacement between the locking and unlocking positions. When the control member is a barrel, the connecting member of the central pusher has a shape complementary to the barrel to be able to drive it in displacement. For example, if the control member is a square section gun, the connecting member is a square section piece that can be inserted into said control member. Furthermore, advantageously and according to the invention, said actuator comprises unidirectional blocking means of said accumulator member, different from the bolt locking means, adapted to be able to block the accumulator member in a loaded position and to be able to authorize the unloading of the accumulator. accumulator member upon receipt of a predetermined command. The operating member is arranged to be able to recharge the energy accumulator member during its movement. However, if the accumulator member is not kept locked in the loaded position, and if the stored energy is not released in the meantime for another use (for example for locking the door), then the energy stored is immediately released to return the actuator to its initial position.

That is, if, for example, the actuator reloads the accumulator member during its stroke from an open position to a closed position, when the user moves the actuator over this race, it charges the accumulator organ. If it releases the operating member before the end of the closure of the opening, the operating member returns to the open position under the effect of the energy accumulated in the accumulator member and the actuator. The loading of the actuator is reversible and it discharges as soon as it has the opportunity, either by locking the locking mechanism, or by bringing the operating member in the open position. However, in some applications, it is desired to avoid this effect and it is desired to conserve the energy stored during the movement of the operating member. In this case, the invention provides for the mounting of unidirectional blocking means, which conserve the energy stored in the accumulator member without it being immediately released for the return of the operating member. In this way the stored energy is retained for locking the locking mechanism at the time the opening is closed and until locking. That is to say that the loading of the actuator is irreversible: once it is loaded, it only discharges for locking the locking mechanism and nothing else. Such unidirectional locking means may comprise, for example, a stopper and in particular a snap-in device.

In addition, these unidirectional blocking means are adapted to allow the release of the energy accumulated on receipt of a predetermined command, in particular on receipt of a command corresponding to the activation of the wall detection means; the control can be of any type, in particular a mechanical control, that is to say a displacement of said unidirectional locking means. Thus, the energy stored in said accumulator member is released when the opening reaches the doorframe, to be used, as provided by the invention, for locking the locking mechanism, and only for locking the locking mechanism in this embodiment.

Furthermore, advantageously and according to the invention, the locking / unlocking device comprises a support of the operating member adapted to be attached and fixed to a front wall of the opening, facing and around a front light formed through the front wall of the opening.

Thus, a locking / unlocking device according to the invention can advantageously be mounted on an opening whose frame is in extension of the amounts of the opening, in the same alignment. Such a support of the operating member therefore allows to have the operating member on a front wall of the opening, so as to make it easily accessible. This arrangement of the actuator thus makes it possible to improve the ergonomics of a device according to the invention.

In the embodiments shown, the locking / unlocking device according to the invention is intended to equip an opening 3 door, window or the like. The opening can indifferently be type striking (swinging, oscillating, etc.), sliding, or other. In the example presented below, the device according to the invention is adapted to be mounted on a sliding leaf on a frame 4. The locking / unlocking device according to the invention comprises a locking mechanism adapted to be recessed in the within a front wall 2 of a sliding door opening 3, window or the like. This locking mechanism comprises at least one bolt 7, 34 and at least one control member 22, 30 of each bolt. Each bolt of a locking mechanism associated with a device according to the invention is for example a hook-type bolt, adapted to be moved between a locked position and an unlocked position, and vice versa, in a direction substantially orthogonal to the direction of rotation. sliding of the opening 3 and parallel to an end edge of the opening coming into contact with a song (or doorframe) with a strike cooperating with the bolt. The front wall 2 is for example a wall of a metal profile or synthetic material forming a peripheral frame opening, square or rectangular, glazed or not. The locking / unlocking device according to the invention further comprises an actuating member 10 in the form of, for example, a handle 10, a handle support 40 enabling the handle 10 to be mounted on the front wall 2 of the handle opening 3 and transmission means interposed between the handle 10 and each bolt 7, 34. The handle support 40 is advantageously formed of a plate 12 and a tubular portion 42, for example circular section, having an internal bore and being adapted to be able to contain the transmission means. The plate 12 and the tubular portion 42 are adapted to allow the passage of a connecting member 14, 19 of the central pusher 17, 18. The handle support 40 is adapted to guide the handle 10 in rotation about an axis 55 relative to the opening 3 according to a pivot connection between at least one closing position relative to the opening and at least one open position relative to the opening corresponding to the unlocked position of each bolt 7, 34.

The handle support 40 and the transmission means are arranged so that the axis 55 of the pivot connection is oriented at least substantially parallel to the opening 3 and orthogonal to the sliding direction. The support 40 can be fixed outside the front wall 2 of the opening 3, facing and around a front slot 1, 9 formed through the front wall 2 of the opening 3.

The handle 10 comprises a handle 46, intended to be taken in hand by the user for locking / unlocking operations and opening / closing of the opening 3 and two arms 44, 45, adapted to be able to connect the handle 46 of the handle 10 to the transmission means. The handle 46 extends substantially parallel to the axis 55 of the pivot connection. The arms 44, 45 of the handle 10 are similar. They are attached substantially symmetrically to the ends of the handle 46 of the handle 10. The transmission means comprise a transmission shaft 11 receiving a central pusher 17, 18 and three rings 15, 16, 61, at least two of which 15, 16 forming cams. The transmission shaft 11 is cylindrical of revolution and has splines 41 on its outer wall which are parallel to each other and continuous along the longitudinal axis of the shaft 11. The transmission shaft 11 has ends non-symmetrical of revolution, for example having two diametrically opposite lugs extending longitudinally along the transmission shaft 11. The ends of the transmission shaft 11 are adapted to correspond to their female conjugates accessible in each of the arms 44, 45 of the handle 10. In addition, the transmission means comprise a central pusher 17, 18 in the form of a ring and having a connecting member 14, 19 adapted to be introduced inside the opening 3 and to cooperate with the control member 22, 30 of each bolt 7, 34. The central pusher 17, 18 is non-integral in rotation with the transmission shaft 11 and is guided in substantially parallel translation in relation to the axis 55 of the pivot connection on the transmission shaft 11 and within the internal bore of the tubular portion 42 of the handle support 40.

In addition, the central pusher 17, 18 is fixed to the front wall of the opening 3 via its connecting member 14, 19 which is itself integral (in translation or in rotation) with the 22, 30 of the bolt 7, 34. In particular, in the embodiment of the invention shown in Figures 2, 3a, 3b and 4a, 4b, 4c, the central pusher 17 and the connecting member 14 are constituted by a single piece which transmits its translational movement along the transmission shaft 11 to the control member 22. In particular, in the embodiment of the invention shown in Figures 5a, 5b and 6a, 6b 6c, the central pusher 18 has the shape of a ring having on an outer side a rack slide 32, and the connecting member 19 is a non-symmetrical shaft of revolution, for example of square section, comprising at least one one of its ends, notches complementary to the rack 32. Thus, the translation of the Central groove 18 along the transmission shaft 11 is transformed into rotational movement of the connecting member 19 about its longitudinal direction. The two rings 15, 16 forming cams and the ring 61 are integral in rotation with the transmission shaft 11 and free in translation, parallel to the axis 55 of the pivot connection, along the splines 41 of the shaft 11. The rings 15, 16 forming cams, the ring 61 and the central pusher 17, 18 are placed around the transmission shaft 11. The bearing 50 of the ring 15 is adapted to come into contact with the mating range 51 of the pusher central 17, 18, in the locking position of the opening 3. The bearing 53 of the ring 16 is adapted to be able to come into contact with the mating surface 52 of the central pusher 17, 18, in the unlocking position of the sash 3 .

Each of the bearing surfaces 50, 51, 52 and 53 of the rings 15, 16 forming cams and the central pusher 17, 18 is non-planar and is adapted to prohibit the simultaneous contact of the bearing surfaces 51 of the central pusher 17, 18 and 50 of the ring 15. forming cam and bearing surfaces 52 of the central pusher 17, 18 and 53 of the ring 16 forming a cam.

The rings 15, 16 forming cams and the central pusher 17, 18 are placed on the transmission shaft 11 so that the central pusher 17, 18 is located between the two rings 15, 16 forming cams. The rings 15, 16 forming cams are placed in the splines 41 of the transmission shaft 11 so that they are offset from each other, that is to say, so that the spans 50 and 53 cam rings 15 and 16 may come into contact with each other, in the absence of the central pusher 17, 18. In addition, the accumulator member 60, an exemplary embodiment of which is advantageously a helical spring 60 compression, and is mounted between the ring 16 and the ring 61, that is to say below the ring 16 and above the ring 61. So that in the locking position of the body control 22,30 (and therefore the central pusher), the spring 60 is at rest (no stored elastic energy) (Figures 3a and 5a). When the control member 22, 30 is in the unlocked position and the handle 10 is in the open position, the spring 60 is also at rest (Figures 3b and Sb). But when the control member 22, 30 is in the unlocking position, the locking means being activated, and the handle 10 is not in the open position (that is to say during a closing movement opening, before reaching the doorframe), the spring is in compression (stored elastic energy non-zero) (Figures 3c and 5c). Indeed, the ring 16 is in the low position because it has been rotated by the transmission shaft 11 during the rotation of the handle 10 from an open position to a closed position, and the pusher central 17, 18 being locked in the unlocking position, said ring 16 has been driven in translation because it forms cam with said central pusher 17, 18. The assembly thus formed by the transmission shaft 11, the rings 15 , 16 forming cams, the ring 61 and the central pusher 17, 18 form a journal which is introduced into the tubular portion 42 of the support 40 of handle. The arms 44, 45 of the handle 10 can then be placed on the transmission shaft 11 so as to be positioned in the same plane. Then, the handle 46 is fixed to the arms 44, 45 of the handle 10, for example by means of clamping screws to be fixed through holes provided in each of the arms 44, 45 of the handle 10. The support 40 of handle can then be attached to the front wall 2 of the sliding door 3.

When the handle is rotated from a closed position to an open position, the upper ring rotates, driven by the splines of the transmission shaft 11, and by friction between the lower bearing surface 50 of the upper ring. 15 and the upper span 51 of the central pusher, said central pusher is moved in translation along the transmission shaft 11 from top to bottom (passage of Figure 3a to 3b (respectively 5a to 5b)). The connecting member 14 is then translated from top to bottom (respectively, the connecting member 19 is rotated). During this step, the intermediate ring 16 also rotates and allows the movement of the central pusher downwards.

When the handle is rotated from an open position to a closed position, the intermediate ring 16 rotates, driven by the splines of the transmission shaft 11, and by friction between the bearing surface 53 of the intermediate ring 16. and the lower span 52 of the central pusher, said locking means 38 being in the blocking position, thus said central pusher being immobilized, said spring 60, being also immobilized downwards by the lower ring 61, is compressed by the displacement towards the bottom of the intermediate ring 16 (passage of Figure 3b to 3c (respectively 5b to 5c)). During this step, the upper ring 15 also rotates and allows the (subsequent) displacement of the central pusher upwards.

The detection of the doorframe by the feeler 38 is made because it comes into contact with the doorframe, and the sensor 38 is movable in translation on the same direction as the sliding leaf, it is moved inwardly of the locking mechanism when the opening bears against the (or near the) jamb. Thus, the probe is advantageously coupled to a return spring whose function is to maintain the protruding probe as long as no external element is pressing the probe, while allowing it to retract when an external element presses on said probe (detection of a wall in particular). The probe advantageously returns to the deactivated position (non-detection of the wall), that is to say more protruding relative to the locking mechanism through said spring when the opening is open.

When the probe 38 detects the proximity of the doorframe, the spring 60 returns to a rest position by expanding vertically upwards (always being immobilized downwards by the lower ring 61) and brings back into contact the bearing surface 50 of the upper ring 15 with the upper span 51 of the central pusher, by moving said central pusher in translation along the transmission shaft 11 from bottom to top (passage of Figure 3c to 3a (respectively 5c to 5a)). During this movement, the connecting member 14, 19 is also moved from an unlocking position to a locking position, by driving the control member and the bolts.

The arms 44, 45 of the handle 10 are adapted to be integral with the transmission shaft 11, in rotation about the axis 55 of the pivot connection of the handle 10. In the following, it is assumed that the position closing the handle 10 of the opening 3 corresponds to a position in which the arms 44, 45 and the handle 46 of the operating handle 10 are the most protruding relative to the opening 3, and that the position opening of the handle 10 of the opening 3 corresponds to a position in which the arms 44, 45 and the handle 46 of the operating handle 10 are the least protruding with respect to the opening 3. However, it it is clear that all other positions of the operating handle relative to the opening 3 corresponding to the locking and unlocking positions of the handle 10 of the opening are possible. These two positions of the handle, visually different and easily identifiable, allow a user to identify the locking state in which the opening 3 is located even when the user is away from the opening 3 and / or is not in front of the opening 3. It should be noted that the device according to the invention is adapted so that the movements of the operating handle 10, for the unlocking and opening of the opening 3, as for the closure and then the locking of the opening 3, are performed so that there is a continuity of movement communicated to the handle 10 of the opening 3 (in the same direction relative to the opening ).

For example, in the case of an opening of the opening 3, a rotation of the handle 10 to maneuver around the axis 55 of the pivot connection in a direction to unlock the opening 3 is followed by the opening opening 3 by a movement in translation in the sliding direction of the opening 3, in a direction such that this translational movement is in continuity with the rotational movement of the handle 10 around the axis 55 Similarly, in the case of a closing of the opening 3, a rotation of the operating handle 10 about the axis 55 of the pivot connection in a direction corresponding to a movement of the handle to a closed position is followed by the closing of the opening 3 by a translational movement in the sliding direction of the opening 3, in a direction such that the displacement of translation is in continuity with the rotational movement of the handle 10 maneuvering around of axis 55. This is the structure mechanical main (handle 10, transmission shaft 11, and support 40) of the locking / unlocking device, which, once the rotation (to a closed position) of the handle performed, transmits to the opening the translational movement that the user applies to the handle 10 maneuvering. Thus, the locking means of the locking mechanism in unlocking position do not take the efforts of the user for moving the door, and they wear out less quickly. There is a disengagement of the closing position of the handle and the locking position of the locking mechanism. Indeed, the locking or unlocking of the locking mechanism is no longer directly dependent on the position of the operating handle: there are situations in which the operating handle is in the closed position although the locking mechanism is in unlocking position (ie during closing maneuver by a user). It is this uncoupling which makes it possible to preserve fragile parts such as the feeler 38 from repetitive shocks, while maintaining optimum maneuverability (the closing operation of the opening is effected with an operating handle in the closed position ).

The locking / unlocking device according to the invention may be adapted to be associated with any type of locking mechanism, in particular with any locking mechanism whose actuation is done by rotation or by translation of the control member of each bolt .

In a first embodiment shown in FIGS. 3a, 3b, 3c and 4a, 4b, 4c, the locking / unlocking device according to the invention is associated with a locking mechanism of the type comprising a technical box 20 comprising a control slider. 22. The control slide 22 comprises a notch 24 allowing the passage of the connecting member 14 of the central pusher 17 for the longitudinal actuation in translation of the control slide 22 for locking or unlocking the bolt 7. The technical box 20 is intended to be mounted on the opening 3 through the front slot 1 formed through the front wall 2. The technical box 20 carries the bolt 7 and all the constituent elements of the locking mechanism is that is to say the various mechanical means allowing the control of the bolt 7 in the locked or unlocked positions of the bolt 7. The technical box 20 is adapted to see being mounted in the front light 1 and fixed in it (Figures 4a and 4b). The longitudinal direction of the front mounting light of the technical housing 20 is orthogonal to the sliding direction of the sliding door 3. The technical box 20 may for example be such as that defined in FR 2 826 994 and be provided with fastening means to the front wall 2 such as those defined in FR 2 826 994. Once the technical housing 20 fixed, the handle 10 operating device and its support 40, associated with the transmission means, are intended to be reported opposite the technical box so that the connecting member 14 of the central pusher 17 enters the notch 24 of the control slider 22. The operating handle 10 and the transmission means are put in place on the opening 3 sliding through the handle support 40 fixed to the front wall 2 of the opening 3 (Figure 4c).

The locking mechanism comprises wall detection means comprising a probe 38, arranged projecting from the edge of the opening and intended to detect the proximity of the opening with the vertical frame (door frame) on which the door is closed. . When the probe comes into contact with the frame, it moves in translation from its locking position (projecting) to its unlocking position, and it moves a blocking element of the control slide of the bolt 7 (the blocking element is part of the blocking means). The control slider is then allowed to move, with the bolt 7 with which it is associated, from an unlocking position to a locking position.

In the locked position the central pusher 17 is in the upper position, abutting against the ring 15 forming a cam. The connecting member 14, secured to the central pusher 17 is also in the up position (Figure 3a). In the unlocked position the central pusher 17 is in the low position and the connecting member 14 is also in the low position (Figure 3b and 3c). In the unlocked position, the handle 10 being in the open position, the central pusher 17 is in the lower position, abutting against the ring 16 forming a cam. In the unlocked position, the handle 10 being held by a user in the closed position, the central pusher 17 is in the lower position, but does not abut against the cam ring 16 because it has lowered by compressing the spring 60 during the rotation of the handle from an open position to a closed position and only a portion of the lower surface 52 of the central pusher 17,18 is in contact with the bearing surface 53 of the intermediate ring 16. A rotation of the operating handle 10 about the axis 55 of the pivot connection, for example a rotation of the order of 45 °, makes it possible to move from one to the other of the closed and open positions. of the opening 3 sliding. But if the opening is not returned to its locking position along the doorframe and the handle 10, in the closed position, is released by a user before the complete closure of the opening 3, the spring back the handle 10 in the open position.

In a second embodiment shown in FIGS. 2, 5a, 5b, 5c and 6a, 6b, 6c, the locking / unlocking device according to the invention is associated with a locking mechanism of "cremone" type. The locking mechanism then comprises a headrest 36 concealing a control rod adapted to be mounted and guided longitudinally sliding relative to the opening 3 sliding, parallel to a song of the opening 3 (Figures 6a and 6b). Once the headrest 36 is placed in the opening 3, the barrel 30 is adapted to be located facing the front light 9 of the front wall 2 of the opening 3. The operating handle 10 and its support 40, associated with the transmission means, are then intended to be reported facing the front wall 2 so that the connecting member 19 of the central pusher 18 can be placed in the barrel 30. The connecting member 19 allows driving the bolt 34 in translation between the locked and unlocked positions. The locking mechanism comprises wall detection means comprising a probe 38, arranged projecting from the headrest 36 and intended to detect the proximity of the opening with the vertical frame (door jamb) on which the door is closed. When the probe comes into contact with the doorframe, it moves in translation from its locking position (projecting) to its unlocking position, and releases the transmission means which are then allowed to return to the locking position, and in doing so to move the control member 30 and the bolt in the locked position, under the effect of the energy restored by the spring 60. In fact the probe allows the control rod to move in translation when its tabs are no longer in the corresponding notches of the rod, which has the effect of allowing all the transmission means between the actuator and the bolts to move from an unlocked position to a locking position. Thus, in this particular embodiment of the invention, said probe 38 is part of both wall detection means, and both blocking means. Indeed, by its displacement between a projecting position of the locking mechanism and a less projecting position (detection of a wall), it prohibits (blocks) or allows the displacement of the bolts 7, 34 between an unlocked position and a position locked.

In particular, the probe 38 directly locks the bolts in the unlocked position since it prohibits the movement of the control rod: the probe has two horizontal tongues that can slide into complementary notches of the control rod when said probe is in position blocking. The probe does not have said horizontal tabs along its entire length, in particular by near its end. Thus, when the probe is pushed inwardly of the locking mechanism, it no longer opposes the movement of the control rod (the tabs are no longer in the notches of the rod).

The central pusher 18 comprises a rack 32 along which the connecting member 19 having complementary notches to the rack 32 moves according to the rotations imposed on the handle 10 by means of the rings 15, 16, 61 and / or spring. In the unlocked position the central pusher 18 is in the high position, abutting against the ring 15, and the connecting member 19 is in the lower position on the rack 32 (Figure 5a). In the locked position the central pusher 18 is in the low position and the connecting member 19 is in the up position on the rack 32 (Figures 5b and 5c). In the unlocked position, the handle 10 being in the open position, the central pusher 17 is in the lower position, abutting against the intermediate ring 16. In the unlocked position, the handle 10 being held by a user in the closed position, the central pusher 17 is in the lower position, but does not abut against the cam ring 16 because it has lowered by compressing the spring 60 during the rotation of the handle from an open position to a closed position and only a portion of the lower surface 52 of the central pusher 17,18 is in contact with the bearing surface 53 of the intermediate ring 16. A rotation of the operating handle 10 about the axis 55 of the pivot connection, for example a rotation of the order of 45 °, makes it possible to move from a closed position to an open position of the handle 10 of the opening 3 sliding. The operating handle 10 and the transmission means are placed on the opening 3 sliding through the handle support 40 fixed to the front wall 2 of the opening 3 (Figure 6c). The locking mechanism of a locking device according to the invention may also be such as that described in FR 2 877 979. The invention may be subject to many embodiments. In particular, it applies to a device comprising one or more handles of different shapes from that shown in the figures, several control rods, any number of bolts and both lateral and vertical (top and bottom of the opening) etc. In addition, any other possible form of the handle support and the handle and arms of the operating handle is conceivable.

A device according to the invention may also have intermediate positions at the closed or open position and / or several closed or open positions. For example one can envisage a device for locking an opening 3 according to the invention in an open position, that is to say, slightly open but without the possibility of opening more opening, especially for an external user, so to avoid intrusions. Nothing prevents either, in a device according to the invention, the accumulator member is, for example, disposed above the central pusher, that is to say between the upper ring 15 and the ring 61 (then assembled from the top of the drive shaft 11).

In addition, an accumulator member according to the invention is not necessarily mechanical and may consist of two magnets repelling or attracting, or a pneumatic cylinder which stores energy by compression of a fluid, etc.
