According to an advantageous and preferred embodiment, the first fastening element 20 and the second fastening element 30 do not comprise the same materials.

For example, the first fastener 20 is preferably composed of a metallic material such as steel, and the second fastener 30 preferably comprises a plastic-based material. This difference in material provides many advantages because it makes it possible to take advantage of the mechanical properties of two different types of materials in the same device. Thus, the metal provides rigidity and strength to the device, while the plastic materials provide flexibility and fluidity to the present device 1.

Advantageously, at least one of the materials constituting the first fastening element 20 has a Young's modulus different from at least one of the materials composing the second fastening element 30.

Preferably, at least one of the materials constituting the first fastening element 20 has a hardness different from at least one of the materials composing the second fastening element 30.

According to one embodiment, the portion that can be fixed to the leaf 2 is fixed by means of fastening means 51a, 51b, 52a, 52b. For example, the fastening means 51a, 51b, 52a, 52b may be screws for screwing the fixable portion to the leaf 2 at the level of a post for example.

According to a particular embodiment, the first fastening element 20 comprises fastening means 51a and 51b to the leaf 2, and the second fastening element 30 comprises fastening means 52a and 52b to the leaf 2.

According to an advantageous and preferred embodiment, the first fastening element 20 and the second fastening element 30 comprise fixing means 51a, 51b, 52a, 52b to the leaf 2 common.

For example, the fastening means 51a, 51b, 52a, 52b may be screws for screwing the first fastening element 20 and / or the second fastening element 30 to the leaf 2.

As indicated above, the present invention relates to a device 1 for locking and unlocking leaves 2 according to a translational movement.

According to a preferred embodiment, it is the first part 10 of the device 1 which performs this translational movement operated by the user. In order to guide this translational movement, the first part 10 comprises at least one orifice, and advantageously two orifices 18a and 18b in order to preferably position two axes 16a and 16b integral with the translational movement.

According to an advantageous embodiment in terms of reliability of the present invention, the axes 16a and 16b comprise a threaded portion so as to be screwed respectively into the orifices 18a and 18b of the first part 10 of the device 1.

According to one embodiment, the first fixing element 20 comprises complementary guide means 21a and 21b comprising locations respectively for the two axes 16a and 16b. These additional guiding means 21a and 21b thus provide guiding and potentially the end of stroke of the first part 10, but also the joining of the first part 10 with the first fastening element 20 outside the translational movement.

According to an embodiment that may be complementary to the previous one, the second fastening element 30 comprises additional guiding means 31a and 31b comprising locations respectively for the two axes 16a and 16b. These additional guiding means 31a and 31b thus provide guiding and potentially the end of stroke of the first part 10, but also the securing of the first part 10 with the second fastening element 30 outside the translational movement.

Preferably, the complementary guide means 21a and 21b and / or the additional guide means 31a and 31b comprise oblong holes configured to receive the axes 16a and 16b.

Advantageously, the complementary guide means 21a and 21b, and the additional guide means 31a and 31b are configured to cooperate with each other. For example, and according to the embodiment illustrated in Figure 1, the complementary guide means 21a and 21b are respectively inscribed in the additional guide means 31a and 31b. Thus, for example, the location for the axis 16a, which is preferably an oblong hole, of the complementary means 21a corresponds with the location for the axis 16a, which is preferably an oblong hole, of the additional means 31a, and The location for the axis 16b, which is preferably an oblong hole, of the complementary means 21b corresponds with the location for the axis 16b, which is preferably an oblong hole, of the additional means 31b. C oblong holes may be carried by portions of the first and / or second fasteners (20, 30) in the form of flanges perpendicular to a base surface of these elements.

Thus, according to FIG. 1, the first part 10 of the device 1 moves in translation in a vertical direction and the axes 16a and 16b in cooperation with the complementary guide means 21a and 21b and the additional guide means 31a and 31b ensure that firstly the guiding of the first part 10 in its translational movement, and secondly the joining of said first part 10 with the part that can be fixed to the leaf 2 outside the translational movement thus allowing increased resistance of the device 1 to the uprooting.

In order to cooperate with the locking member located in the amount of the leaf 2, the present invention cleverly takes advantage of a pinion 14 cooperating with a square 15 passing through the fixable portion and preferably the first fastening element 20 and the second element 30. The square 15 is configured to fit on the one hand in the pinion 14 and on the other hand in the locking member of the leaf 2. Advantageously, the axis of rotation of the pinion 14 is orthogonal to the translational movement of the device 1, and preferably, the axis of rotation of the pinion 14 is orthogonal to the face of the leaf 2.

According to an advantageous embodiment, the pinion 14 passes through the first fastening element at a central hole 14a and the second fastening element 30 at a central hole 14b. Advantageously, the central hole 14b of the second fastening element 30 comprises a collar 14c configured to register in the central hole 14a of the first fastening element 20 so as to surround the pinion 14. Preferably, this collar is composed of the same material than the second fastener 30 to facilitate its production. According to this embodiment, the flange 14c ensures the rotational guidance of the pinion 14. The flange 14c serves as a guiding surface for the rotation of the pinion 14. The pinion 14 advantageously comprises at least one metallic material, steel or aluminum and can be in Zamak. Cleverly, the interaction of the pinion 14 with the flange 14c allows rotation with a very low coefficient of friction.

According to a preferred embodiment, the first part 10 of the device 1 comprises a cavity 17 containing at least one rack 12a, and preferably two racks 12a and 12b, being located opposite one another, and being positioned in to cooperate with the pinion 14. This cooperation is then possible by the presence of at least one toothed sector 13a at the pinion 14.

Advantageously, the pinion 14 comprises a toothed sector 13a and a toothed sector 13b. The toothed sector 13b makes it possible to cooperate with only one of the two racks 12a and 12b.

According to one embodiment the toothed sector 13a is less than 360 degrees, advantageously less than 270 degrees and preferably less than 180 degrees or even 90 degrees, and the toothless sector 13b is greater than 0 degrees, advantageously greater than 90 degrees and preferentially greater than 180 degrees or even 270 degrees.

Advantageously, the translation of the first portion 10 rotates the pinion 14 by means of one of the two racks 12a or 12b. This rotation of the pinion 14 then drives the square 15 with which it cooperates. This rotation of the square 15 is then transmitted to the locking member of the leaf 2 so as to lock or unlock it.

According to an advantageous embodiment and so as to create a retaining point of the first part 10 in its translational movement, the present invention provides at least one and preferably two stop elements 32a and 32b. These stop elements are advantageously part of the second fixing element 30 and passes through the first fastening element 20 respectively at openings 22a and 22b so as to come into contact with the toothed portion 13a of the pinion 14 when the first part 10 device 1 arrives at the end of the race.

Advantageously, these stop elements 32a and 32b comprise an elastically deformable material, preferably identical to the material of the second fastening element 30 in order to facilitate its production. This elastic deformation is configured to brake, preferably create a retaining point of the pinion 14 in its rotation when the first part 10 reaches the end of the race in its translational movement.

According to one embodiment, the stop elements 32a and 32b each respectively comprise a deformable element 33a and 33b comprising a blade portion 33a and 33b projecting from the second fastening element 30 so as to pass through the first fastening element 20 respectively through the openings 22a and 22b.

Advantageously, said blade portions 33a and 33b comprise a surface composed of a relief. For example, this relief can be similar to that of said racks so as to cooperate with the toothed sector 13a of the pinion 14. Due to the elastic property of these blades 33a and 33b, they can deform during their interaction with the toothed sector 13a pinion 14 so as to create a retaining point of the first portion 10 of the device 1, or to stop, preferably smoothly, the stroke of the first portion 10 of the device 1.

Advantageously, the blade portions 33a and 33b are located opposite one another so that the toothed sector 13a of the pinion 14 is positioned between each of them. Due to the presence of the toothed sector 13b of the pinion 14, it only cooperates with one of the two blade portions 33a and 33b when the translational movement of the first portion 10 reaches the end of the stroke.

According to one embodiment, each of the two blade portions 33a and 33b is configured to stop the translational movement of the first portion 10 respectively in the first position and in the second position. This cooperation mechanism will be detailed in the description of FIGS. 2a to 3d.

According to one embodiment, each of the two blade portions 33a and 33b is configured to create a retaining point of the first portion 10 respectively in the first position and in the second position.

As previously indicated, the present invention allows two possible configurations in the choice of locking and unlocking positions. Figures 2a to 2d illustrate a first configuration and Figures 3a to 3d illustrate a second configuration.

In the remainder of the description, we will assign the first position to the position of the first part 10 translated upwards and the second position to the position of the first part 10 translated downwards.

According to a so-called first configuration embodiment illustrated in FIGS. 2a to 2d, the first position corresponds to the unlocking of the leaf 2 and the second position corresponds to the locking of the leaf 2.

Figures 2a and 2b show a view of the pinion 14 along its axis of rotation from the leaf 2 to the handle 11 so as to visualize the cavity 17 containing the two racks 12a and 12b.

FIG. 2a represents the first position according to this first configuration, that is to say the unlocking of the leaf 2, that is to say the end-of-travel position of the first part 10 in its upward translational movement. . As illustrated by this figure, in this configuration, the toothed sector 13a of the pinion 14 cooperates with the first rack 12a, and not with the second rack 12b.

FIG. 2b illustrates, according to this same configuration, the second position of the device 1, that is to say the locking position of the leaf 2, that is to say the end-of-travel position of the first part 10 in its translational movement down. Still according to this first configuration, the toothed sector 13a of the pinion 14 cooperates with the first rack 12a.

Advantageously, the toothed sector 13b of the pinion 14 makes it possible not to cooperate with the second rack during the translational movement, which would block said movement.

FIGS. 2c and 2d show a view of the pinion 14 along its axis of rotation from the handle 11 towards the leaf 2 so as to visualize the interaction of the pinion 14 with the stop elements 32a and 32b respectively comprising the blade portions 33a and 33b.

Figure 2c shows the device 1 in the first position, position identical to Figure 2a. The first part 10 is therefore positioned upwards and has reached its end of course. The toothed sector 13a of the pinion 14 is indeed in interaction with the raised surface of the blade portion 33b. This blade portion 33b undergoes elastic deformation when a tooth of the toothed sector 13a of the pinion 14 comes into contact with it. This deformation then allows the passage of one or more teeth of the toothed sector 13a of the pinion 14 and mechanically maintains the first part 10 in the first position, preventing without a mechanical effort from the user a return of the device 1 in another position.

Figure 2d shows the device 1 in the second position, position identical to Figure 2b. The first part 10 is therefore positioned downwards and has reached its end of travel. The toothed sector 13a of the pinion 14 is indeed in interaction with the raised surface of the blade portion 33a. This blade portion undergoes elastic deformation when a tooth of the toothed sector 13a of the pinion 14 comes into contact with it. This deformation then allows the passage of one or more teeth of the toothed sector 13a of the pinion 14 and mechanically maintains the first part 10 in the second position, preventing without a mechanical effort from the user a return of the device 1 in another position.

According to a so-called second configuration embodiment illustrated in FIGS. 3a to 3d, the first position corresponds to the locking of the leaf 2 and the second position corresponds to the unlocking of the leaf 2.

Figures 3a and 3b show a view of the pinion 14 along its axis of rotation from the leaf 2 to the handle 11 so as to visualize the cavity 17 containing the two racks 12a and 12b.

FIG. 3a represents the first position according to this first configuration, that is to say the locking of the leaf 2, that is to say the end-of-travel position of the first part 10 in its upward translational movement . As illustrated by this figure, in this configuration, the toothed sector 13a of the pinion 14 cooperates with the second rack 12b, and not with the first rack 12a.

FIG. 3b illustrates, according to this same configuration, the second position of the device 1, that is to say the unlocking position of the leaf 2, that is to say the end-of-travel position of the first part 10 in its translational movement down. Still according to this first configuration, the toothed sector 13a of the pinion 14 cooperates with the second rack 12b.

Advantageously, the toothed sector 13b of the pinion 14 makes it possible not to cooperate with the first rack during the translational movement, which would block said movement.

FIGS. 3c and 3d show a view of the pinion 14 along its axis of rotation from the handle 11 towards the leaf 2 so as to visualize the interaction of the pinion 14 with the stop elements 32a and 32b respectively comprising the blade portions 33a and 33b.

Similarly to Figure 2c, Figure 3c shows the device 1 in the first position, position identical to Figure 3a. The first part 10 is therefore positioned upwards and has reached its end of course. The toothed sector 13a of the pinion 14 is indeed in interaction with the raised surface of the blade portion 33b. This blade portion 33b undergoes elastic deformation when a tooth of the toothed sector 13a of the pinion 14 comes into contact with it. This deformation then allows the passage of one or more teeth of the toothed sector 13a of the pinion 14 and mechanically maintains the first part 10 in the first position, preventing without a mechanical effort from the user a return of the device 1 in another position.

In a similar manner to Figure 2d, Figure 3d shows the device 1 in the second position, position identical to Figure 3b. The first part 10 is therefore positioned downwards and has reached its end of travel. The toothed sector 13a of the pinion 14 is indeed in interaction with the raised surface of the blade portion 33a. This blade portion undergoes elastic deformation when a tooth of the toothed sector 13a of the pinion 14 comes into contact with it. This deformation then allows the passage of one or more teeth of the toothed sector 13a of the pinion 14 and mechanically maintains the first part 10 in the second position, preventing without a mechanical effort from the user a return of the device 1 in another position.

Thus the role of the stop elements 32a and 32b is similar in the first and in the second configurations since their interaction with the pinion 14 only depends on the translational movement and not on a choice of locking or unlocking position. Conversely, the choice of the rack interacting with the pinion 14 gives the present invention an important adaptability in the choice of locking and unlocking positions. Indeed, the user can choose between one of the two configurations without this requiring the change of the device, but simply the rotation of the pinion 14 so that it interacts with one or the other of the two racks 12a or 12b.

According to one embodiment, the present invention relates to a method of mounting the device 1 on a leaf 2 comprising a locking member. Said method comprises the following steps: - fitting of the first fastening element 20 with the second fastening element 30 so that the stop elements 32a and 32b pass respectively through the openings 22a and 22b of the first fastener element 20 and so that the flange 14c of the central hole 14b of the second fastening element 30 passes through the central hole 14a of the first fastening element 20. - Fastening by means of the fastening means 51a, 51b, 52a, 52b on the amount of the leaf 2 of the first and second fastening element 20 and 30 of the device 1 so that the central hole 14b coincides with the hole of the locking member for receiving the square 15, and so that the second fixing element 30 is interposed between the leaf 2 and the first fixing element; - Inserting the square 15 in the locking member; - Choice from one of two possible configurations, that is to say choosing the locking position and the unlocking position of the leaf 2 by rotation of the square 15 in the locking member; - Inserting the pinion 14 according to the configuration chosen by the user in the aligned holes 14a and 14b so that the pinion 14 is partially surrounded by the flange 14c and that the pinion 14 cooperates with the square 15, and so that the toothed sector 13a is oriented to the right or left relative to the axis of the translational movement according to the chosen configuration. - Installation of the first part 10 so as to cooperate the pinion 14 with one of the two racks 12a or 12b according to the configuration chosen by the user; - Placement of the axes 16a and 16b at the orifices 18a and 18b corresponding to the oblong holes of the complementary guide means 21a and 21b and additional guide means 31a and 31b; - Clamping of the axes in the orifices 16a and 16b.

The present method is quick and easy to implement, and once the first fastener 20 and the second fastener 30 are installed, the first part 10 can be adapted in its installation according to the configuration chosen by the user. In addition, this configuration can easily be changed at any time simply by dismantling the first part 10 of the device 1.

The present invention is not limited to the previously described embodiments and extends to all the embodiments covered by the claims.
