Description

FIELD OF THE INVENTION

This presentation relates to the field of openings of joinery, such as doors, windows, French windows or other types of doors intended to close an opening.

The present disclosure relates more particularly to a displacement control device for a rod for such a door leaf.

STATE OF THE PRIOR ART

The document US 2010/043504 A1 discloses a conventional moving control device for a rod as well as patents US 5,839,767 A and US 5,927,767 A .

Also known are control devices, which conventionally comprise a handle forming an operating member adapted to be operated by a user from the opening; and a control member forming a one-piece control member most often pivotally mounted on the leaf, so that a first end of said piece serves as a driving portion configured to cooperate with the rod to move this last, and that another end of said piece serves as a coupling portion configured to couple said workpiece in displacement with the handle, so that a maneuver of the handle by a user actuates the movement of the control part .

Thus, a maneuvering of the handle can allow, via the control part, the movement of the rod, for example between a locking position of the opening in the closed position and an unlocking position of this opening of the door. so that it can open. Such a locking position may for example be obtained using at least one locking assembly consisting of a bolt and an associated strike, said bolt being provided integral with the rod (or door frame) and said keeper being provided integral with the frame (or the rod) so that an engagement of the bolt and keeper with each other locks the opening in the closed position in its frame. Maneuvering the handle can then allow, by moving the rod, a disengagement of the bolt and striker relative to each other to unlock the opening and allow opening.

It is observed that the players on the market of these control devices are more numerous. So there is a pressing need for the release of a more competitive product.

PRESENTATION OF THE INVENTION

The information disclosed by the present inventors, in the context of the present description developed hereafter, is the result of their desire to arrive at a solution that best meets the aforementioned need.

This solution is to provide the control member not in one piece, as is conventionally the case, but on the contrary to separate the drive portion and the coupling portion into separate parts to be assembled together.

This solution, which at first sight may seem disadvantageous in that it complicates the manufacturing process by requiring the manufacture and assembly of at least one piece more than for conventional devices, actually opens the way for an improvement. the manufacturing process which substantially improves its efficiency compared to the conventional manufacturing process and, therefore, the competitiveness of the device thus produced. This improvement is to involve the step of assembling the driving part and the device with each other (hereinafter referred to as "step E40") later in the manufacturing process, so as to to be able to execute, during the manufacturing process, a larger sequence of successive so-called "standard" steps (ie which remain, each, unchanged from one particular model of device to another) upstream of this step E40 of the assembly of the training part, which it is chosen to firstly change from one model to another.

In addition, the exact position of step E40, within the chain of steps constituting the thus improved manufacturing method, can be freely adjusted to optimize the process more precisely, in particular according to the respective weights attributed to the various parameters of the process. specifications, in particular the overall efficiency of the process and its modularity.

For example, in some embodiments of this improved manufacturing method, it may be desirable first to optimize the overall efficiency of the process. In this case, step E40 can in particular be used at the very end of the process, so that all manufacturing steps preceding this step E40 are standard steps. Therefore, we can achieve a standard device base, which is common to the entire range of device models considered because incorporating only standard parts, which comes next, at the very end of the manufacturing process, add the piece incorporating the training part. This last piece is thus, unlike the other parts of the device forming the standard device base, a piece non-standard because deliberately configured differently from one model to another to be able to bear alone the footprint of all the distinctive characteristics of each of these models (especially dimensional), which are intended to allow their adaptation to the specificities of joinery to which they are destined respectively.

In particular, it can be provided that the shape and dimensions of the driving portion are adapted specifically for each of the models of the device, so that these models can, once incorporated into the joinery for which they are intended respectively, allow the movement of the rods respectively mounted on these windows.

In addition, in some embodiments of the manufacturing method, the overall efficiency of the process can be further optimized by going straight out of step E40 of the industrial process, in particular to allow the end user of the device to perform itself. at the moment it deems it appropriate, the assembly of the driving part and the device with each other. In this case, the product may for example be put on sale packaged in a package comprising the common base of the device and the training part not assembled with each other, so that it is the end user. which itself performs this assembly step.

Moreover, this configuration can allow the driving part to be manufactured independently of the aforementioned manufacturing process, during another, secondary process, better adapted to repeated parameter changes to pass a part model. from one training to another, which can also contribute to lower manufacturing costs. In addition, such a reduction in costs can, for example, be exploited to manufacture at lower cost a greater number of different variations of the training part, so as to expand a given range of devices by a larger number of different models, each comprising the same common base but a proper variation of the training part, to cover a wider range of different joineries each having specific dimensional characteristics (for example with regard to the location of the location of the rod relative to the location of the joinery dedicated to the incorporation of the device). Moreover, since the assembly of the driving part with the common base of the device can be carried out at any time with this configuration, this secondary method can be implemented by the same manufacturer as that executing the main manufacturing process, in parallel with this last, or by another manufacturer. In any case, an optimization of production costs can be expected.

Moreover, in some embodiments of the manufacturing method, it may be desirable first of all to optimize the modularity of the process. In this case, at least one step after step E40 may in particular be involved in the process, in particular at least one non-standard step so that the method comprises at least two non-standard steps during each of which the device can be diversified from one model to another for greater design freedom. In addition, the method may, despite this configuration, be more efficient than the conventional method, if the execution of step E40 occurs later in the process than conventionally, as explained above.

The fact that the user can try several different models in situ , without having to return to the store to exchange the product, can represent a significant saving of time and money for this user. In addition, given that these different models of drive part can be manufactured during a secondary process optimized for frequent passage in the production line from one model to another, the extra cost generated by the commercialization of the device with several models of training part may remain insignificant in view of the above advantages.

Moreover, the fact of allowing the user to perform himself the assembly of the training part and the device with each other can also be used for the passage to offer this user the choice between several different configurations for this assembly, which respectively allow access to several different relative positions between the training part and the carpentry, once the device incorporated in the latter.

In this example, the control device 1 is configured to move a rod 130 movable to be movably incorporated into the opening 100.

Such a rod 130 may be used to, for example, allow locking / unlocking of the opening 100 relative to the frame 120 when the rod 130 is translated along the opening (for example, along a longitudinal direction of the opening, as shown on the figure 1 . One could also expect, without going out of the present description, to provide a translation of the rod along a lateral direction of the opening) between a locking position and an unlocking position.

As it is illustrated in a more visible way on the Figures 2 and 3 , the device 1 comprises an operating member 20 adapted to be mounted movably on the opening 100 and to be operated by a user; and a control member 40 adapted to be mounted movably on the opening 100.

In this example, the device 1 further comprises a support, which is adapted to be fixedly incorporated into the opening 100, and through which the operating and control members 40 are each mounted on the opening 100.

In this example, the operating member 20 comprises a gripping portion adapted to be grasped directly by a user to operate the operating member 20. More particularly, this gripping portion forms a handle projecting from the opening 100 of in order to be more easily grasped by the user, who can, for example, close the hand around the handle to maneuver.

In this example, as shown in figure 6 , the operating member 20 comprises a base piece 22, one piece, to which are assembled two other parts 24 and 26 to form the gripping portion. These pieces 22, 24 and 26, once assembled together, form a unitary unit in displacement (which moves as a single unit, during a movement of the actuating member 20).

In this example, the operating member 20 is adapted to be pivotally mounted on the opening 100. More particularly, in this example, the operating member 20 is adapted to be pivotally mounted about a parallel pivot axis X the main plane P of the opening, when the actuating member 20 is incorporated in the opening. This main plane P is parallel to the two main faces of the opening 100 and coincides with the main plane of the joinery, when the opening 100 adopts its closed position.

In this example, the operating member 20 is configured such that, when the operating member is mounted on the opening 100, the operating member 20 is able to pivot in a pivot plane perpendicular to the main plane P of the opening 100.

In this example, the operating member 20 is adapted to be pivotally mounted on the opening 100 through the support. More particularly, in this example, the support supports an axis 5 around which the actuator 20 can pivot. Even more particularly, in this example, the base part 22 of the operating member 20 has a bore in which the axis 5 is introduced to allow the actuating member 20 to pivot.

Moreover, in this example, the control member 40 is dissociated from the operating member 20.

In this example, the control member 40 is dissociated into several parts assembled together.

More particularly, in this example, the control member 40 is dissociated into two parts to be assembled to one another. More specifically, the control member 40 comprises, in this example, a first piece 50 and a second piece 60, 60 '(which, in this example, is provided in duplicate in the device 1, as will be seen a little more away) configured to be directly assembled to each other.

In this example, the first piece 50 has a driving portion 52, which is formed in one piece with this first piece 50, and which is configured for, during a movement of the control member 40, cooperate with the rod 130 to move it between its locking positions and unlocking the opening of the opening 100.

In this example, the rod 130 comprises a bar 132 and a driver 134 (for example, a cylindrical roller as shown in FIG. figure 3 ) and the driving portion 52 is configured for, during a movement of the control member 40, cooperate directly with the trainer 134 to move the bar 132 of the rod 130.

In this example, the drive portion 52 has a portion of fork with two branches 57, which are configured so that, during movements of the control member 40 once the latter incorporated in the opening 100, cooperate with the driver 134 interposed between the two branches to move the bar 132 of the rod 130.

In this example, the bar 132 is adapted to be housed in a groove that has the opening, in particular rabbet, in its thickness (for example, a groove called "European").

In this example, the trainer 134 is adapted to protrude from the bar 132 in this groove.

In this example, the driving portion 52 is adapted to protrude into this groove, when the control member 40 is mounted on the opening 100, so that the cooperation between the driving portion 52 and the 134 trainer is performed in the groove. In particular, in this example, the opening 100 has an opening (not shown) opening into the groove, through which the drive portion 52 can pass to protrude into this groove.

In this example, the control member 40 is adapted to be pivotally mounted about a pivot axis parallel to the main plane P of the opening, when the control member 40 is incorporated in the opening 100.

In this example, the pivot axis of the control member 40 coincides with the pivot axis X of the operating member 20.

In this example, the control member 40 is configured such that, when the control member 40 is mounted on the opening 100, the control member 40 is able to pivot in a pivot plane perpendicular to the plane main P of the opening 100.

In this example, the drive portion 52 is flat, so that when the control member 40 is mounted on the opening 100, the plane of this portion is perpendicular to the main plane P of the opening 100 and the training part 52 can move in this plane.

In this example, the trainer 134 of the rod 130 is able to protrude from the bar 132 in a direction perpendicular to the plane of the driving portion 52, so that the fork portion of the training portion 52 can, during a movement of the control member 40, cooperate with the trainer 134 to move the bar 132.

Furthermore, in this example, the control member 40 comprises a coupling portion 61 configured to couple in displacement the control member 40 and the operating member 20 so that a maneuver of the control member actuation actuates the movement of the control member 40.

In this example, the coupling portion 61 and the operating member 20 are disassociated from one another and configured to be coupled in motion directly to each other.

More particularly, in this example, the coupling portion 61 and the actuating member 20 have respective abutment portions able to mutually cooperate to couple in translation said coupling portion 61 and said actuator 20 directly to each other. 'other.

In this example, the second part 60, 60 'incorporates the coupling part 61.

Moreover, in this example, as illustrated in Figures 9A to 9D the first part 50 and the second part 60, 60 'comprise respective assembly parts configured to cooperate directly with each other when assembling the first and second parts directly to one another.

In this example, the respective assembly parts are adapted to allow the first and second parts, once assembled to one another, to move as a single unit, during a movement of the control member. 40. In other words, the respective assembly parts allow, when mutually cooperative, to make the first and second unitary parts moving.

More particularly, in this example, the first part 50 comprises a first assembly portion 54, which has a first guide portion; a first part of clipping; and a first abutment portion.

In this example, the first assembly portion 54 has a notch 55 having edges 56 forming the first guide portion.

More particularly, in this example, the first assembly portion 54 is such that the notch 55 gives it a fork shape with two branches 57, which have respective edges 56 which are directly opposite one another , and which are parallel to each other so as to form a slide portion as a first guide portion.

In addition, in this example, the two branches 57 respectively have free ends 59 which form the first clipping part.

In addition, in this example, the notch 55 has another edge 53 which connects the aforementioned edges 56 to each other. This edge 53 forms the first abutment portion.

Furthermore, in this example, the second part 60, 60 'comprises a second assembly part, which has a second guide portion; a second part of clipping; and a second abutment portion.

In this example, the second assembly portion has a projecting portion 65 having walls 66 forming the second guide portion.

More particularly, in this example, the second assembly portion is such that the protruding portion 65 has two walls 66 which are parallel to each other so as to form a slider portion as a second guide portion.

In addition, in this example, the second assembly part has two elastic tabs 67 which form the second clipping part.

More particularly, in this example, the two elastic tabs 67 are disposed on either side of the projecting portion 65, so as to be able to move away from the latter and be biased towards the latter by elasticity. In addition, the two elastic tabs 67 have respective more protruding portions 69 formed at their respective free ends.

Furthermore, in this example, the projecting portion 65 has another wall 63 which connects the aforementioned walls 66 together. This wall forms the second abutment portion.

We will now describe in more detail a method of assembling the device according to this example.

The first step is to arrive at the assembly stage represented at Figure 9A . At this stage, all the parts of the device 1 are assembled together, with the exception of the first part 50. There are thus, at this stage, two objects completely dissociated from one another.

The first of these two objects is a base of the device, comprising all the parts of the device assembled together, with the exception of the first part 50. In particular, at this stage, the second part 60 is already assembled with the body maneuver 20, coupled in displacement with the latter. This base can, if desired, be a standard basis for all device models to be manufactured, incorporating only standard parts. This base can therefore be entirely manufactured and assembled during the same industrial process, and be marketed as is.

Moreover, the second of these two objects is the first piece 50. It can, if desired, be a piece whose shape and dimensions are specifically adapted for each model of the range of devices to be manufactured, in particular so that that each model is adapted for incorporation on a different model of carpentry. For example, it can be expected that the dimensions of the training portion 52 are different from one model to another, as will be seen later in this paper.

Furthermore, during this first step, it is possible to prepare the coming assembly of the first and second parts, by presenting the first and second guide parts in alignment with each other, this alignment materializing a direction assembly D.

In particular, in this example, this alignment is obtained when the edges 56 of the legs 57 of the first assembly part are parallel to the walls 66 of the projecting portion 65 of the second assembly part. In this case, the management assembly D is contained in a plane parallel to these edges 56 and walls 66 and aligned.

The second step is then to make a relative displacement of the first and second parts towards each other along the assembly direction D to arrive at the assembly stage shown in FIG. Figure 9B . At this stage, the first and second guide portions 56, 66 begin to cooperate directly with each other, while the first and second clipping portions 56, 69 are still spaced from each other (therefore disengaged from each other). On their side, the first and second abutment portions 53, 63 are further spaced from each other.

In particular, in this example, at this stage, the edges 56 and walls 66 begin to cooperate directly with each other, respectively, while the ends 59 and 69 of the first and second clipping portions are spaced from each other, respectively, of so that the elastic tabs 67 are at rest. On their side, the edge 53 and the wall 63 are spaced from each other.

The third step then consists in bringing the first and second parts closer together more relative to each other by relative movement of these two parts towards each other along the assembly direction D, so as to be able to arrive at the assembly stage represented at Figure 9C . In this example, this relative displacement is guided by the mutual cooperation of the first and second guide portions with each other. More particularly, in this example, the slide and slider portions, which are respectively formed by the edges 56 and the walls 66, slide one inside the other in the assembly direction D to achieve this guiding effect according to this direction.

Moreover, at the assembly stage represented in Figure 9C , the first and second clipping parts begin to cooperate with each other. More particularly, in this example, at this point the ends 59 and 69 come into contact with each other, without the fact that the ends 59 urge the elastic tabs 67 in displacement. On their side, the first and second abutment portions 53, 63 are less distant but still spaced from each other.

The fourth step then consists in bringing the first and second parts closer together more relative to each other by relative movement of these two parts towards each other along the assembly direction D, so as to be able to arrive at the assembly stage represented at Figure 9D . At this stage, the first and second clipping portions 59, 69 cooperate directly together by clipping effect.

More particularly, in this example, at this stage, the ends 59 cooperate with the ends 69 to urge the elastic tabs 67 towards their respective spacings with respect to the projecting portion 65.

On their side, the first and second abutment portions 53, 63 are even less distant but still spaced from each other.

The fifth step then consists in bringing the first and second parts further together relative to one another by relative movement of these two parts towards each other along the assembly direction D, until that the first and second clipping portions 59, 69 are mutually engaged to prevent any further relative displacement in a first direction which corresponds to the direction of a distance from the first and second abutment portions 53, 63 relative to the other.

More particularly, in this example, at this stage, the ends 59 have passed the ends 69, which allows the elastic tabs 67 to return to their respective initial positions at rest and thus prevent the ends 59 from crossing the ends 69 into the reverse.

On their side, the first and second abutment portions 53, 63 are now in contact with one another, which prevents any additional relative displacement in the opposite direction to the first direction (ie in the direction corresponding to the direction of further approximation of the first and second abutment portions 53, 63).

Furthermore, in this example, the device 1 comprises a pair of second parts 60 and 60 'arranged so that, when the control member 40 is incorporated in the joinery, the second parts 60 and 60' of said pair are symmetrical relative to each other in a plane of symmetry perpendicular to the main plane of the joinery.

In this example, the two second parts 60 and 60 'are identical to each other.

The first piece 50 may be assembled, optionally, any of these two second pieces 60 and 60 ', which provides a first combination of two separate assembling configurations to the user.

In addition, in this example, when the user has chosen with which of the two second pieces 60 or 60 'he will assemble the first piece 50, another combination of two distinct configurations of assembly vis-à-vis that of the two second pieces 60 or 60 'thus previously chosen.

Indeed, in this example, it is possible, by a simple reversal of the first piece 50 with respect to a plane of the latter said reversal plane, assemble said first piece 50 with the second piece 60 or 60 'previously selected according to, optionally, a first assembly configuration or a second assembly configuration distinct from the first.

To do this, in this example, the portion of the first piece 50 which incorporates the notch 55 has a first plane of symmetry corresponding to the aforementioned turnaround plane.

Moreover, in this example, said portion has a second plane of symmetry perpendicular to the first plane.

In addition, in this example, the control member 40 is configured such that, when the control member 40 is incorporated in the joinery, the turning plane is perpendicular to the main plane of the joinery.

Moreover, in this example, the second part 60, 60 'has a plane of symmetry which, when the first part 50 and the second part 60, 60' are assembled together, coincides with the second plane of symmetry of the portion of the first piece 50 which incorporates the notch 55.

In addition, in this example, the driving portion 52 of the first piece 50 also has a symmetrical shape with respect to the aforementioned second plane of symmetry.

• configuration '0' : configuration pour une menuiserie à deux ouvrants (dits respectivement de service et semi-fixe, l'ouvrant 100 précité correspondant alors à l'ouvrant de service) avec ouverture de l'ouvrant mobile sur la droite : voir les figures 10A et 10B ;

• configuration '3': configuration for a joinery to a single opening which opens on the left: see the Figures 13A and 13B .

Furthermore, in this example, as mentioned above, the device 1 comprises a support, which is adapted to be fixedly incorporated into the opening 100, and through which the actuating members 20 and control 40 are, each, mounted on the opening 100.

In this example, the support is dissociated from the opening 100 and adapted to be fixed thereto.

In addition, in this example, the support comprises a hollow housing 100 adapted to be fixed on the opening 100, inside which the operating and control members 40 are each at least partly housed.

In this example, the housing 10 has a wall 11 which is adapted to come directly opposite the opening 100, when the housing 10 is fixed on the opening 100, and which has an opening 12 through which a first portion of the first piece 50 protrudes from the wall 11 towards the outside of the casing 10, during a movement of the control member 40, allow the drive portion 52 to cooperate with the rod 130 to move it, while that another portion of the first piece 50 projects from the wall 11 towards the inside of the casing 10 to allow the assembly of the first 50 and second 60, 60 'pieces to one another.

More particularly, in this example, the opening 12 is adapted such that, from an intermediate assembly stage of the device 1 in which the second part 60, 60 'is inside the housing 10, coupled to the operating member 20, while said other portion of the first piece 50 is still outside the housing 10 because not yet assembled with the second piece 60, 60 ', said other portion can then be introduced through this opening 12 inside the housing 10 to allow the assembly of the first and second parts to one another.

Furthermore, in this example, the wall 11 of the housing is adapted to come into contact with a main face of the opening 100, in particular directly applied to one of its uprights.

In addition, in this example, the housing 10 is dissociated in addition to separate housing parts assembled together (see figure 6 ). More particularly, in this example, these housing parts together form a closed cowling, for example a hermetic cowling.

Moreover, in this example, the device 1 is such that the coupling portion 61 is configured to couple the control member 40 with play. the operating member 20, so as to allow a relative movement of the control member and the actuating member relative to each other.

In addition, in this example, the device 1 comprises a first locking member 80 adapted to be incorporated in a movable manner to the opening 100 so as to be able to move between a locking position (see FIG. Figures 14, 15A , 15B , 19A and 19B ) and an unlock position (see Figures 15C , 19C to 19F ) the displacement of the actuator 20 outside a predetermined position of said actuator.

Furthermore, in this example, the device 1 comprises a second locking member 90 dissociated from the first 80 and able to be incorporated in a movable manner to the opening 100 so as to be able to move between a locking position (see FIG. Figures 15A and 19A ) and an unlock position (see Figures 15B and 19B to 19F ) of the displacement of the first locking member 80.

Moreover, Figures 16 to 18 represent a second example of a device according to the present disclosure.

This second example differs from the aforementioned first example only in that its operating member is arranged so that it comprises a gripping portion 200 (for example a handle) that can be grasped to manipulate the operating member, and maneuvering member is adapted to move on a given displacement stroke without actuating the movement of the control member, between a first position (see FIG. figures 18 ) in which the gripping portion 200 is more easily grasped and a second position (see figure 17 ) in which the gripping portion 200 is less easily grasped.

In this second example, the device 1 is configured such that the predetermined position is the second position of the operating member 20.

Moreover, the description of the characteristics which have been described in association with the first example is omitted for this second example, for the sake of brevity of the present disclosure. However, it is obvious that this second example may incorporate one or more of these characteristics without departing from the scope of this presentation.
