DESCRIPTION

Locking device for a semi-fixed swing Technical sector

The present invention relates to the field of doors, windows, window doors or other types of hinges intended to close a gap.

It refers, more specifically, to a locking device for a semi-fixed leaf that cooperates with a mobile leaf to close a gap.

State of the art

By mobile swing, it is intended to designate that of the two hinges that normally opens first, when both hinges are both initially in the closed position. Normally, the mobile leaflet thus comprises gripping means intended to allow its opening, as well as a locking mechanism of the mobile leaflet on the semi-fixed leaflet and / or on the contour of the opening. Consequently, by semi-fixed leaflet it is intended to designate, the leaflet that normally only opens once the mobile leaflet is open.

Locking devices are already known for a semi-fixed leaf that cooperates with a mobile leaf to close a bay. These known devices comprise a locking element that can be unlocked once the mobile leaf is open. This unlocking is operated, for example, automatically with the help of a sliding element (see in particular patent DE 342584C or BE415068A). Otherwise, this release can be operated with the help of a handle or a small lever.

Thus, according to the latest known devices, to unlock the semi-fixed swing, when the latter is in the closed position after the opening of the mobile leaf, it is necessary to manually carry out an unlocking operation. Also, to lock the semi-fixed leaflet, it is necessary to manually perform the reverse operation before closing the mobile leaf.

These known devices have, consequently, the disadvantage of specifying the active contribution of the user to proceed to the unlocking or blocking of the semi-fixed swing, which is annoying, in particular, for a physically diminished user.

Another drawback of these known devices is that in order to remain hidden when the two hinges are closed, the blocking element and the means that allow them to be unlocked are very small, in which case their manipulation is uncomfortable, or they can be handled more easily, in which case its volume is greater, which affects the overall aesthetics of the frame equipped with these hinges.

Object of the invention

The present invention proposes to substantially remedy these inconveniences.

More particularly, in claim 1 a blocking device according to the present invention is defined.

Thanks to the present invention, a locking or unlocking operation of the semi-fixed leaflet is not carried out manually by the user, but, on the contrary, automatically by closing or opening the mobile leaflet, which allows the user to free himself from the annoying operations. necessary for the known devices described above.

More specifically, thanks to the present invention, a simple opening of the mobile leaf is enough to unlock the semi-fixed leaf. In fact, the opening of the mobile leaflet causes a rupture of the cooperation between the cam and the control body, which allows the first retention body and the control body to enter a release configuration by the pushing of the means of impulse of the blocking element. Conversely, a simple closing of the mobile leaf is enough to block the semi-fixed leaf. In fact, the closing of the mobile leaflet causes a cooperation between the cam and the control organ, which allows to overcome the impulse exerted by the impulse means on the blocking element and to force the first retention organ as well as the control organ to scroll to the lock settings.

On the other hand, thanks to the present invention, the first retention organ and the control organ are suitable for movable mounting, either on the contour of the opening or on the semi-fixed swing, so that it can move substantially parallel to the plane of the contour, when the semi-fixed swing is in its closed position. In this way, thanks to the present invention, a locking element and the cam cooperating therewith can be realized in an extremely discreet and low-volume way, which allows to preserve the general aesthetics of the frame.

It is to be understood that thus, according to this first variant, a locking device for a semi-fixed leaf that cooperates with a mobile leaf to close a bay is obtained, the mobile and semi-fixed leafs extending substantially in a plane of the contour of the bay when the two they are in the closed position, said device comprising:

a blocking element that includes a first retention organ suitable for cooperating with a second integral retention organ with the semi-fixed swing and a control organ, the first retention organ and the control organ being suitable for movable mounting on the contour of the opening in the vicinity of a meeting area of the two hinges, so that they can move substantially parallel to the plane of the contour of the opening between a locking configuration, in which the first retention organ is suitable for cooperating with the second retention organ to block the semi-fixed swing and a release configuration, in which the second retention organ can be released; means for driving the locking element towards its release configuration; and a cam destined to be integral with the mobile leaf to cooperate with the control body so as to drive the blocking element towards its blocking configuration.

Advantageously, according to a second particular variant that represents an alternative to the first variant mentioned above, the second retention organ is integral with the contour of the opening in the vicinity of a meeting area of the two hinges, while the first retention organ and The control organ is suitable for movable mounting on the semi-fixed swing.

It is to be understood that thus, according to this second variant, a locking device for a semi-fixed leaf that cooperates with a mobile leaf to close a bay is obtained, the mobile and semi-fixed leafs extending substantially in a plane of the contour of the bay when the two they are in the closed position, said device comprising:

a blocking element that includes a first retention organ suitable to cooperate with a second solidarity retention organ with the contour of the opening in the vicinity of a meeting area of the two hinges and a control organ, the first retention organ being and the control organ suitable for movable mounting on the semi-fixed swing so that, when the semi-fixed swing is in its closed position, the first retention organ and the control organ can move substantially parallel to the plane of the contour of the opening between a blocking configuration, in which the first retention organ is suitable for cooperating with the second retention organ to block the semi-fixed leaflet and a release configuration, in which the second retention organ can be released; means for driving the locking element towards its release configuration; and a cam designed to be integral with the mobile leaf to cooperate with the control body so as to drive the blocking element towards its blocking configuration, when the semi-fixed leaf is in its closed position.

Advantageously, according to a particular arrangement of this second variant, the first retention organ and / or the control organ are suitable for movable mounting in the recess of the semi-fixed leaflet. Advantageously, the first retention organ and the control organ are integral in their displacement, which simplifies the kinematics of the device.

Preferably, the first retention organ and the control organ are formed in a single piece, which allows a simplification of the device and a reduction in its manufacturing cost.

According to an advantageous alternative, the first retention organ and the control organ are not integral in their movement, but both are suitable for movement describing independent or analog paths.

Advantageously, the first retention organ and the control organ are mounted on a common displacement guide piece, suitable for mounting either on the contour of the opening, when the first variant is implemented, or on the semi-fixed swing, when it is implemented The second variant. It is understood that thus the first retention organ and the control organ can be easily placed, since it is enough to mount these two organs on the moving guide piece and then mount this piece, either on the contour of the opening or on the semi-fixed swing This results in a gain in assembly time. In addition, the subset constituted by the first retention organ, the control organ and the moving guide piece can thus be standardized so that it can be mounted interchangeably, either on any type of contour of a bay intended to be closed by two hinges or well on any type of semi-fixed swing.

first variant

Advantageously, the cam is an independent part of the mobile leaf and is suitable for solidarity with the latter, which allows the cam to be provided in the form of a standard element that can be mounted indifferently on any type of mobile leaf.

Advantageously, the control body has a suitable ramp to cooperate with the cam.

It is understood that the realization or rupture of the cooperation between the control organ and the cam, when a movement of the mobile leaf has been started to close or open it, respectively, so that it can be carried out more progressively, which allows to improve the resistance to wear of the device and the user to resent less of the transitions of the device configurations during the closing or opening of the mobile leaf.

Advantageously, one of said first and second retention organs includes a male part suitable for fitting into a female part formed on the other retention organ, which makes it possible to improve the yields of the lock of the semi-fixed swing when the blocking element is in the configuration lock In particular, the cooperation of the first and second retention organs can thus better resist a forced opening of the semi-fixed leaflet. In addition, the functional clearance required to allow the realization or rupture of the cooperation of the first and second retention organs thus can be minimized, so that the residual mobility of the semi-fixed leaflet can be minimized when locked in the closed position.

On the other hand, according to claim 1, it is understood that the semi-fixed leaflet, when the mobile leaf is open, so that the first retention organ is in the release configuration, can be maintained despite everything in the closed position, which allows to avoid an untimely opening of the semi-fixed swing, in particular, due to the effect of the wind or its own weight when it is not plumb.

According to claim 1, the second retention organ is elastically movable to engage on the retention relief and to be released therefrom when the blocking element is in its release configuration.

It is understood that the second retention organ can thus, when the blocking element is in its release configuration, engage on the retention relief or be released therefrom by a simple pressure exerted by the user on the semi-fixed leaflet, which is practical and little annoying to the user.

The first retention organ includes a blocking relief which, in the blocking configuration, is more pronounced than the retention relief in the release configuration.

It should be understood that, in the blocking configuration, the blocking relief protrudes more than the retention relief so that the first retention organ can cooperate with the second retention organ to block the semi-fixed leaflet in the closed position. It follows that, in the locking configuration, the semi-fixed leaflet cannot be released even when the user drives its opening by exerting a pressure on it.

According to claim 1, the retention relief is formed by the blocking relief when the first retention organ is in the release configuration.

It is understood that the first retention organ, in addition to ensuring the blocking of the second retention organ when it is in the blocking configuration, can also thus ensure the retention of the second retention organ when it is in the release configuration, which allows simplifying the device.

According to an advantageous alternative, which is not according to the invention, the retention relief is fixedly fixed, either with respect to the contour of the opening, when the first variant is implemented, or to the semi-fixed swing, when the second variant is implemented.

Preferably, the first retention organ and the control organ are mounted on the common plate mentioned above and the retention relief is formed on this plate, which simplifies the device and also allows it to be easily provided in the form of standard elements.

Advantageously, the first retention organ and the control organ are suitable for pivoting mounting, either on the contour of the opening, when the first variant is implemented, or on the semi-fixed swing, when the second variant is implemented, which allows simplifying the device implementing simple movements.

According to an advantageous alternative, the first retention organ and the control organ are suitable for sliding fittings, either on the contour of the opening, when the first variant is implemented, or on the semi-fixed swing, when the second variant is implemented, which allows simplifying the device by implementing simple movements.

Detailed description of the invention

In Fig. 1, a semi-fixed leaf 2 and a mobile leaf 1 are both shown movable mounted in a frame 3 so that they can cooperate together to close a bay.

According to the illustrated example, the two hinges 1 and 2 have substantially identical dimensions.

The frame 3 is essentially composed of two uprights 6 and 7 on which the two hinges 1 and 2 have been mounted, and by two crossbars 4 and 5 perpendicular to the uprights 6 and 7.

A blocking element 10 of a blocking device according to the first variant of the present invention is mounted substantially in the middle of the recess of at least one of the two crossbars of the frame 3, for example, the crossbar 5.

Thus, since the two hinges 1 and 2 of the illustrated example are mounted in a frame 3 to close a gap, on the one hand, they have substantially identical dimensions and, on the other hand, the locking element 10 is mounted on the contour of the bay, in the immediate vicinity of a meeting area of the leaflets 1 and 2.

In the same way, according to the illustrated example, another blocking element 10 of another locking device according to the first variant of the present invention is mounted substantially in the middle of the recess of the other crossbar 4.

Thus, in the illustrated example, it is envisaged to use two locking devices according to the present invention, so that everything that will be described below, for one blocking device is equally valid for the other blocking device .

In figure 2, a blocking element 10 of a blocking device made according to a first embodiment according to the first variant of the present invention is shown.

The blocking element 10 comprises a first retaining member 14 suitable for cooperating with a second retaining member integral with the semi-fixed leaf 2 which will be described later.

The blocking element 10 also includes a control organ 16 suitable for cooperating with a cam designed to be integral with the mobile leaf 1 which will be described later.

According to the illustrated example, the blocking element 10 is presented substantially in the form of a bar, so that the first retention member 14 and the control organ 16 are formed in a single piece.

The thickness of the bar 10 varies along its length, so that it can be considered that the bar 10 is essentially constituted by three longitudinal sections 12, 14, 16 each having an average thickness that is proper to it.

The first section 12 is formed from a first longitudinal end of the bar 10 and has a lower average thickness.

The second section 14 is formed in the extension of the first section 12 and has an average thickness of greater

value. The second section 14 constitutes, in the illustrated example, the first retaining organ of the blocking element 10.

The third section 16 is formed in the continuity of the second section 14, extends to the second longitudinal end of the bar 10 and has an average thickness of intermediate value. The third section 16 constitutes, in the illustrated example, the control organ of the blocking element 10.

According to the illustrated example, there is a ramp 17 formed at the second longitudinal end of the bar 10. This ramp 17 is configured to cooperate with the cam that will be described later.

The bar 10 has an opening 18 that crosses its entire thickness and is formed along a part of the first section 12 and along the entire second section 14.

The second section 14 thus crossed by the opening 18 is in the form of two lugs 14A and 14B that are substantially parallel to each other and constitute the points where the bar 10 has a greater thickness. The two lugs 14A and 14B thus define a female part that is suitable to cooperate with the second retention organ that will be described later.

According to the illustrated example, the bar 10 is slidably mounted according to its longitudinal direction on a plate 20, which, according to this embodiment, constitutes a sliding guide piece, on which both the first retention organ and the organ are mounted of control.

In figure 4, the assembly of the bar 10 on the plate 20 is shown. The plate 20 has two longitudinal grooves 22, of which one is open longitudinally, which are each suitable for receiving a corresponding elongated pin 19 , which protrudes below the bar 10 so that the latter can slide according to its longitudinal direction on the plate 20 when the bar 10 is mounted on the plate 20.

The bar 10 is held on the plate 20 with the aid of a clamping piece 30 which is installed on the plate 20 being introduced through the opening 18 of the bar 10 and which is fixed on the plate 20.

The clamping piece 30 includes a base 33 that is fixed on the plate 20 by screwing and which has a notch 34 that defines a retention relief, in this case in a hollow, substantially V-shaped quite open, suitable for cooperating with the second retention body that will be described in more detail below.

The clamping piece 30 also has a joint wall 36 formed at one end of the base 33 and from which an projecting part 32 is projected. This projecting part 32 ensures a guiding role of the transfer of the bar 10 by cooperation with the two lugs 14a and 14B when the bar 10 slides on the plate 20.

The plate 20 is fixed on the recess of a cross member 5 of the frame 3 by screwing, so that the bar 10 can slide according to a direction substantially parallel to the plane of the contour of the opening.

Thus, according to the illustrated example, the plate 20 is fixed on the contour of the opening. Since the holding element 30 is fixed on the plate 20, the retention relief which is defined by the notch 34 of the base 33 of the holding element, consequently, is fixedly fixed with respect to the contour of the opening.

In addition, since in the illustrated example the first retention organ and the control organ are formed in a single piece, these two elements are integral in their displacement, so that they slide in solidarity according to a direction substantially parallel to the plane of the contour of the in vain when the bar 10 slides.

By plane of the contour of the opening, it is intended to designate the plane in which the two hinges 1, 2 substantially extend when both are in the closed position. Thus, according to the example illustrated in Figure 1, the plane of the contour of the opening also corresponds to the plane that passes through the two crossbars 4 and 5 of the frame 3, or, to the plane that passes through the uprights 6 and 7 of the frame 3.

Thus, the bar 10 on which the first retaining member 14 and the control body 16 are formed is adapted to move substantially parallel to the plane of the contour of the opening between a first position, illustrated in Figure 2, and a second position, illustrated in figure 3.

The first position is obtained when the bar 10 is in a configuration called release of the second retaining organ in which the first section 12 of the bar 10 is in front of the notch 34 of the holding piece 30. The average thickness of the first section 12, which is the smallest of the bar 10, is provided so that the edges of the notch 34 are substantially flush with the part of the opening 18 formed in the first section 12 of the bar. Thus, the relief formed by the thickness of the first section 12 and the retention relief formed by the notch 34 of the fastening element 30 does not really protrude one more than the other.

The second position is obtained when the bar 10 is in a configuration called blocking of the second retention organ, in which the two lugs 14A and 14B are presented opposite the notch 34 of the clamping piece 30. Since the two lugs 14A and 14B represent the parts of the bar 10 of greater thickness, the two lugs 14A and 14B protrude more than the notch 34. It follows that the blocking relief thus defined by the two lugs 14A and 14B is, in this configuration of blocking, more pronounced than the retention relief defined by the notch 34 of the holding element 30, it should be noted that according to the illustrated example, this retention relief is identical in the release configuration and in the blocking configuration.

The blocking device of the present invention includes means for propelling the blocking element towards its release configuration.

In the example illustrated in Figure 4, these means are presented in the form of a primary spiral spring 40 which is housed in a reinforcement formed in the lower part of the third section 16 of the bar 10 and which is suitable for cooperating, by a part, with an edge of this reinforcement and, on the other hand, with the joint wall 36 of the fastener 30.

The primary spiral spring 40 thus arranged is suitable for driving the rod 10 so that it slides into its first position illustrated in Figure 2 and described above, therefore, towards its release configuration.

As already mentioned briefly before, the first retention element of the blocking element is configured to cooperate with a second retention organ integral with the semi-fixed swing.

According to the example illustrated in Figures 5 and 6, the second retention organ is presented in the form of a rod 50 which is slidably mounted at the lower end of the recess of the stud of the semi-fixed swing 2 and which is maintained on the latter by means of a support 52 screwed onto said recess.

The rod 50 includes a hollow part 51 that is guided in translation by the support 52 and a projection 53 that is formed in the extension of the hollow part 51 and which defines a suitable male part to fit in the female part of the defined bar 10 by the two lugs 14A and 14B.

As illustrated in Figures 6 and 7, a sliding of the wand 50 in a direction approximating the wand 50 towards the traverse 5 of the frame 3, that is, towards the bar 10, is elastically driven with the help of a spring of secondary spiral 56 which is housed in the hollow part 51 of the rod 50 so as to cooperate, on the one hand, with a cylindrical pin 54 which is in solidarity with the support 52 and which crosses the hollow part 51 and, on the other hand, with an edge of the hollow part 51 of the rod 50 which is defined in a wall from which the projection 53 is formed.

According to the example illustrated in Figures 5, 7 and 8, the end of the projection 53 of the rod 50 has a ramp with a shape complementary to that of the retention relief defined by the notch 34 of the fastener 30, so that the retaining relief materialize a hard point of attachment of the projection 53 of the rod 50.

Thus, when the bar 10 is in its release configuration, the end of the projection 53 can be held in the retaining relief due to its complementary shape, as illustrated in Figure 7. According to the illustrated example, the attachment of the hitch of the projection 53 in the retention relief is accentuated by the impulse exerted on the rod 50 by the secondary spiral spring 56.

Furthermore, when the bar 10 is in its release configuration, it is observed that the relief formed by the thickness of the first section 12 and the retention relief do not really protrude one more than the other. It follows that the end of the projection 53 of the rod 50 can be easily released from the retention relief by a simple pressure exerted on the semi-fixed leaf 2. In fact, since the rod 50 is elastically movable mounted on the semi-fixed leaf 2 and given that the end of the projection 53 has a ramp shape, the rod 50 can pass over the retaining relief as well as over the relief formed by the thickness of the first section 12 to free itself from the hard holding point, as illustrated in the figure 8.

On the other hand, as illustrated in Figure 2, the first section 12 of the bar 10 has a slope 13, so that when the bar 10 is in the release configuration and the semi-fixed swing 2 is open, it is possible to pass easily the projection 53 of the rod 50 above the relief formed by the thickness of the first section 12 to cause the projection 53 to engage in the retention relief.

On the other hand, when the bar 10 is in its locking configuration, it is observed that the blocking relief of the bar 10 defined by the two lugs 14A and 14B is more pronounced than the retention relief defined by the notch 34 of the clamping element 30, as illustrated in Figure 9. It follows that the male part defined by the end of the projection 53 of the rod 50 is embedded in the female part defined by the two lugs 14A and 14B, which prevents the release of the rod 50 even when a pressure is exerted on the semi-fixed swing 2 and due to this fact it blocks the latter in the closed position.

The blocking device of the present invention also includes a cam designed to be integral with the mobile leaf to cooperate with the control body so that the blocking element is propelled towards its blocking configuration.

According to the example illustrated in Figures 10 to 12, the cam 60 is an independent part of the mobile leaf 1 which is fixed on the latter in the vicinity of an area of encounter with the bar 10.

The cam 60 has a useful part 62 that is suitable for cooperation, when the mobile leaf 1 is placed in

closing position, with the ramp 17 of the third section 16 of the bar 10 that defines the control organ. The cooperation between the useful part 62 of the cam 60 and the ramp 17 of the bar 10 causes the latter to slide towards its locking configuration, which allows the semi-fixed swing 2 to be locked in the closed position.

Next, a blocking device according to a second embodiment according to the first variant of the present invention is described.

According to the example illustrated in Figure 13, the locking element is substantially in the form of a jogger 100 with two ends 140 and 160, so that the first retention organ and the control organ are formed in a single piece.

In this example, the first end 140 of the jogger 100 is constituted by the first retaining member of the locking element. It is presented substantially in the form of a parallelepiped in which an opening 180 has been formed that crosses the entire thickness of the first end 140.

The first end asf crossed by the opening 180 has two abutment walls 140A, 140B which are

substantially parallel to each other and thus defining a female part, suitable for cooperating with the second

organ of retention substantially identical to that described in the first embodiment.

The second end 160 of the jogger 100 in this example is constituted by the control organ of the blocking element. It is presented substantially in the form of a prism, which allows it to define an inclined portion 162 which forms the lower part of the second end 160 and a substantially straight portion 164 which forms its upper part.

There is a perforation 110 formed in the jogger 100 at the height of the junction zone of its two ends.

According to the illustrated example, there is a ramp 170 formed at the second end 160. This ramp 170 is configured to cooperate with the cam that will be described later.

According to the illustrated example, the jogger 100 is pivotally mounted on a plate 200, which, according to this embodiment, constitutes a sliding guide piece, on which both the first retention organ and the control organ are mounted.

In figure 15, the assembly of the jogger 100 on the plate 200 is shown. The plate 200 has an axis support 220 on which a pivot axis 300 of the jogger 100 can be inserted to mount and maintain this last pivot on the plate 200.

The plate 200 includes a first projecting part, formed on the longitudinal periphery of the plate 200 and having an inclined portion 130 and a second projecting part, formed on the plate, so that it can protrude through the opening 180 of the jogger 100 when it The latter is mounted on the plate 200.

A notch 340 is formed in the second protruding part of the plate 200, thus defining an analogous retention relief to that described above for the first embodiment and which is suitable for cooperating with the second retention organ.

The plate 200 is fixed on the recess of a cross member 5 of the frame 3 by screwing, so that the jogger 100 can pivot according to a direction substantially parallel to the plane of the contour of the opening. The retention relief protruding from the plate 200 is also mounted fixed with respect to the contour of the opening.

Thus, the jogger 100 on which the first retention organ 140 and the control organ 160 are formed is adapted to move substantially parallel to the plane of the contour of the opening between a first position, illustrated in Figure 13, and a second position, illustrated in figure 14.

The first position is obtained when the jogger 100 is in a release configuration of the second retention organ in which the first end 140 of the jogger 100 is in a low position and the second end 160 of the jogger 100 is in a position high. The arrangement of the first end of the jogger 100 in a substantially parallel shape and a suitable choice of its thickness allow

that the two abutment walls 140A and 140B are substantially flush at the height of the part that most protrudes from the retaining relief formed by the notch 340. Thus, the relief formed by the two abutment walls 140A and 140B of the jogger 100 and the retention relief formed by the notch 340 of the plate 200 does not really protrude one more than the other.

The second position is obtained when the jogger 100 is in a locking configuration of the second retention organ in which the first end 140 of the jogger 100 is in a high position and the second end 160 of the jogger 100 is in a position low. It follows that the two abutment walls 140A and 140B protrude more than the notch 340. It follows that the blocking relief thus defined by the two abutment walls 140A and 140B is, in this blocking configuration, more pronounced than the retention relief defined by notch 340 of plate 200.

The blocking device according to the second embodiment also includes means for driving the blocking element towards its release configuration.

In the example illustrated in Figure 13, these means are in the form of a leaf spring 400 of which one end rests on the plate 200 and on which the other end rests on the inclined portion 162 of the second end 160 of the jogger 100 .

The laminated spring 400, thus positioned, is suitable for propelling the pivoting jogger 100 towards its first position, illustrated in Figure 13 and described above, therefore, towards its release configuration.

As indicated above, the first organ of retention of the blocking element, according to the second embodiment, is configured to cooperate with a second organ of retention with the semi-fixed leaflet.

According to the example illustrated in Figure 16, the second retention organ is presented in the form of a rod that is substantially identical to the rod described above for the first embodiment and, consequently, will not be detailed again for the second mode. of realization.

The projection of the rod defines a male part suitable for fitting into the female part of the jogger 100 defined by the two abutment walls 140A and 140B.

According to the illustrated example, the end of the rod projection has a ramp that is complementary to that of the retention relief defined by the notch 340 of the plate 200, so that the retention relief materializes a hard point of attachment of the projection of the wand, analogous to the one described above for the first embodiment.

Thus, when the jogger 100 is in the release configuration, it is observed that the two abutment walls 140A and 140B of the jogger 100 and the retention relief formed by the notch 340 of the plate 200 do not actually protrude the one more than the other. It follows that the end of the rod projection can be easily released from the retention relief by a simple pressure exerted on the semi-fixed leaf 2.

In addition, as illustrated in Figure 13 and as mentioned above, the first protruding part of the plate 200 has an inclined portion 130. This inclined portion 130 plays the same function of facilitating the postage of the thickness as the slope 13 of the first section 12 of the bar 10 described for the first embodiment.

Finally, when the jogger 100 is in the locking configuration, it is observed that the blocking relief defined by the two abutment walls 140A and 140B protrudes more than the notch 340 of the plate 200. It follows that the defined male part by the end of the rod projection it is embedded in the female part defined by the two stop walls 140A and 140B, which prevents the release of the wand even when a pressure is exerted on the semi-fixed swing 2 and due to this fact it blocks to the latter in closing position.

The blocking device, according to the second embodiment, also includes a cam intended to be integral with the mobile leaf to cooperate with the control organ so as to drive the blocking element towards its blocking configuration.

According to the example illustrated in Figures 18 to 21, the cam 600 is an independent part of the mobile leaf 1 which is fixed on the latter in the vicinity of a meeting area with the jogger 100.

The cam 600 has a useful part 620 that is suitable for cooperation, when the mobile leaf 1 is placed in the closed position, with the ramp 170 of the second end 160 of the jogger 100 defining the control organ. The cooperation between the useful part 620 of the cam 600 and the ramp 107 of the jogger 100 causes the latter to pivot towards its locking configuration, which makes it possible to block the semi-fixed swing 2 in the closed position.

In the two embodiments described above, an implementation of the first variant has been illustrated

according to the present invention, in which the second retention organ is integral with the semi-fixed swing and in which the first retention organ and the control organ are suitable for movable mounting on the contour of the opening in the vicinity of an area of meeting of the two wings.

Next, a blocking device according to a third embodiment is described which represents an illustrative and non-limiting example of the second variant according to the present invention and which is illustrated with reference to Figures 22 to 31.

Thus, as illustrated in particular in Figure 31, according to this third embodiment, the second retention organ 50 'is integral with the contour of the opening in the vicinity of a meeting area of the two wings, while that the first retention organ 14 'and the control organ 16' are suitable for movable mounting on the semi-fixed leaf 2.

According to the illustrated example, the first retention organ 14 'and the control organ 16' are formed in a single piece that constitutes the blocking element 10 'of the blocking device.

Consequently, the first retention organ 14 'and the control organ 16' are integral in their displacement.

According to this example, it has been decided to mount the blocking element 10 'on a sliding guide piece 20' which is fixed on the semi-fixed leaf 2 and which is independent of the blocking element 10 '.

More particularly, according to this example, the sliding guide piece 20 'comprises a fixing part 22' suitable for fixing on the semi-fixed leaf 2 and a guide part 24 'on which the locking element 10' is mounted.

The displacement guide piece 20 'is generally square shaped with two wings that are substantially perpendicular to each other and form respectively the guiding part 24' and the fixing part 22 '.

The wing that forms the guiding part 24 'has a first face rotated from the side from which the wing that forms the fixing part 22' stands tall and a second face opposite the first face.

Two reinforcement ribs 25 'protrude from this first face and come to join the wing that forms the fixing part 22'.

The blocking element 10 'is mounted on the wing that forms the guiding part 24' so that it protrudes from the second face of the latter, therefore, from the side opposite to the side from which the wing forming the fixing part 22 'stands.

As illustrated in particular in Figures 22, 23 and 28, the displacement guide piece 20 'is suitable for mounting on the semi-fixed leaf 2 in the vicinity of the meeting area of one end of the 8' upright of the semi-fixed leaf 2 intended to face the mobile leaf 1 and one end of one of the two crossbars 9 'of the semi-fixed leaf 2.

In this way, the blocking element 10 'is mounted in a recess of the semi-fixed leaf 2.

More particularly, the wing that forms the fixing part 22 'is housed in a groove 7' which has this stud 8 '.

The wing that forms the guiding part 24 'is housed at least in part, for example, in all its thickness, in a

slot 4 'that has this crossbar 9' and that connects with slot 7 'of the stud 8'.

The wing that forms the fixing part 22 'has one or more through holes, two in particular, suitable to be crossed by fixing screws (not shown) to fix the sliding guide piece 20' on the semi-fixed swing 2 .

The blocking element 10 ', once mounted on the sliding guide piece 20', protrudes at least in part from this crossbar 9 '. It follows that at least a part of the blocking element 10 'protrudes from the traverse 9' in the direction of a traverse 5 'of the frame, when the semi-fixed swing 2 is in its closed position.

Consequently, in order to prevent the blocking element 10 'from impeding the closing of the semi-fixed swing 2, it is provided that this cross-member 5' of the frame 3 'has a free space in which the projecting part of the blocking element 10 is received when the semi-fixed swing 2 is in its closed position.

More particularly, according to this example, the traverse 5 'of the frame has a lower part 3' that materializes this free space. In fact, the traverse 5 'has a step that defines this lower part 3'.

According to the illustrated example, the first retaining member 14 'and the control organ 16' are suitable for mounting sliders on the semi-fixed leaf 2.

For this, the blocking element 10 'is suitable for sliding mounting on the sliding guide piece 20'.

More particularly, one of the elements between the blocking element 10 'and the sliding guide piece 20' includes a female guiding portion 11 'suitable to cooperate with a male guiding portion 21' which includes the other of said elements so that the blocking element 10 'can slide over the sliding guide piece 20'.

According to the illustrated example, the blocking element 10 'is substantially in the form of a bar, in which, on a first face thereof, the female guiding portion 11' is formed, while the male guiding portion 21 ' it is formed on the second side of the wing that forms the guiding part 24 'of the displacement guide piece 20'.

In this way, the first face of the bar that forms the blocking element 10 'faces the wing of the sliding guide piece 20' which forms its guiding part 24 '.

According to the illustrated example, the female guiding portion 11 'consists of a groove, while the male guiding portion 21' consists of a slide whose dimensions are adapted so that it is suitable to fit into the groove and slide into the latter. .

Preferably, both the groove and the slide are T-shaped so that the blocking element 10 'can slide with respect to the sliding guide piece 20' while hindering a de-strengthening of the blocking element 10 'with respect to the sliding guide piece 20 '.

According to the illustrated example, the blocking element 10 'includes a reinforcement formed on a second face of the bar that is opposite the first face. It follows that the blocking element 10 'has two walls that are substantially parallel to the plane of the semi-fixed swing 2, with the blocking element 10' being mounted on the semi-fixed swing 2. Thus, these two walls are substantially parallel to the plane of the contour of the opening when the semi-fixed swing 2 is in its closed position.

Each of these two walls has a free space, for example, a cut-out, so as to present a portion of smaller thickness 12 'and a portion of greater thickness 14'.

As illustrated in particular in Figures 26 and 27, the control element 16 'is formed in the continuity of the two thicker portions 14' from the side closest to the upright 8 'of the semi-fixed swing 2, the locking element falling 10 'is mounted on the semi-fixed swing 2.

The two thinner portions 12 'are formed respectively in the continuity of the two thicker portions 14' on the side furthest from the stud 8 'of the semi-fixed leaf 2, with the blocking element 10' being mounted on the semi-fixed leaf 2 .

The two thicker portions 14 'form two lugs 14A' and 14B 'that are substantially parallel to each other and thus define a female part that is suitable for cooperating with the second retention organ that will be described later.

Thus, according to this particular example, these two lugs 14A 'and 14B' are both suitable to move substantially parallel to the plane of the contour of the opening, when the semi-fixed swing 2 is in its closed position.

The second side of the wing that forms the guiding part 24 'of the displacement guide piece 20' has a notch 28 'which defines a retention relief, in this case, in a hollow, with a rounded shape (or in other words , with concave shape), suitable to cooperate with the second retention body that will be described in more detail below.

Thus, according to the illustrated example, since the displacement guide piece 20 'is fixed on the semi-fixed leaf 2, the retention relief, which is defined by the notch 28' that this part presents, therefore, is mounted fixed with respect to the semi-fixed swing 2.

As illustrated in Figure 31, in order to prevent the male guiding portion 21 ', which has the wing that forms the guiding part 24', does not hinder the cooperation of this retention relief with the second retention organ , an incision is made in the male guide portion 21 'at the place where it corresponds to the notch 28', so that the male guide portion 21 'is dissociated into two sections that extend to one side and another of the notch 28 '.

The blocking element 10 'is suitable for moving substantially parallel to the plane of the semi-fixed swing 2 by translation.

When the semi-fixed swing 2 is in its closed position, the blocking element 10 'is suitable for moving substantially parallel to the plane of the contour of the opening by sliding between a first position, illustrated in Figures 23, 25 and 26, and, a second position, illustrated in particular in Figures 27, 28 and 29.

The first position is obtained when the blocking element 10 'is in a configuration called release of the second retention organ, in which the two smaller portions 12' respectively of the two walls of the blocking element 10 'are presented in front of the notch 28 'of the sliding guide piece 20'.

The thickness of the two thinner portions 12 'is adapted so that the edges of the groove 28' are substantially flush with the free edge of the two thinner portions 12 ', as illustrated in particular in Figure 23 .

It follows that the relief formed by the thickness of the smaller thickness portions 12 'and the retention relief formed by the notch 28' of the displacement guide piece 20 'does not really protrude one more than the other.

The second position is obtained when the blocking element 10 'is in a configuration called blocking of the second retention organ, in which the two lugs 14A' and 14B 'of the blocking element 10' are presented opposite the notch 28 'of the sliding guide piece 20'.

The thickness of the two lugs 14A 'and 14B' is adapted so that the latter protrude more than the notch 28 'on either side of the latter.

It follows that the blocking relief thus defined by the two lugs 14A 'and 14B' is, in this blocking configuration, more pronounced than the retention relief defined by the notch 28 'of the displacement guide piece 20'.

It should be noted that this retention relief is identical in the release configuration and in the blocking configuration, which can be repealed without deviating from the scope of the present invention.

The blocking device according to this third embodiment also includes means for driving the blocking element 10 'towards its release configuration.

According to the illustrated example, in particular in Figure 31, these means are presented in the form of a first spiral spring 40 '.

This first spiral spring 40 'is housed, in part, in the cavity formed by the two ribs 25' of the displacement guide piece 20 'described above.

The first of the two ends of the primary spiral spring 40 'is fixed to the displacement guide piece 20', while the other end of this spring is fixed to the locking element 10 '.

The primary spiral spring 40 'asf arranged is suitable for propelling the blocking element 10' in sliding towards its first position called release, described above.

As already mentioned briefly before, the first retention organ of the blocking element 10 'is suitable for cooperating with a second retention organ that is integral with the contour of the opening in the vicinity of a meeting area of the two hinges when They are both in the closed position.

For example, the second retention organ can be positioned on the contour of the opening in the precise location in which the two hinges are when they are both in the closed position or displaced with respect to this location on the side of the semi-fixed leaf or the leaf mobile, only on condition that the position of the second retention organ is adapted to allow its cooperation with the first retention element of the blocking element 10 'when the semi-fixed leaf 2 is in its closed position.

According to the example illustrated in Figure 31, the second retention organ is presented in the form of a 50 'teton.

The useful end of the 50 'teton is rounded, while its other end is widened and rotated on the contour side of the opening.

The stud 50 'is mounted mobile in a hollow sleeve 54' fixed with respect to a support piece 52 'of the stud 50',

the sleeve 54 'being, according to the illustrated example, formed integrally with this support piece 52'.

The diameter of the sleeve 54 'is adapted so as to guide in translation the teat 50', in particular, in the direction perpendicular to the traverse 5 'of the frame.

The 50 'teton is elastically mobile.

For this, according to the illustrated example, an elastic impulse element, in particular a second spiral spring 56 ', is placed at the bottom of the hollow sleeve 54' so that it rests on the support piece 52 '.

The stud 50 'is placed in the sleeve 54' with its widened end resting on this spring 56 'so that the stud 50' is elastically driven by the latter in a sense of distance with respect to support piece 52 '.

It follows that the displacement of the stud 50 'in a sense of approximation of said stud 50' towards the semi-fixed swing 2, when the latter is in its closed position, is elastically driven by the elastic impulse element.

The free edge of the sleeve 54 'deforms once the stud 50' has been introduced into the sleeve 54 ', so that the free end of the sleeve 54' undergoes a local reduction in its diameter so that the stud 50 'is skewered it is retained by cooperation of its widened end with the deformed free edge of the sleeve 54 'and thus prevent the stud 50' from escaping from its housing due to the impulse exerted by the impulse element.

The local reduction of the diameter of the free end of the sleeve 54 'allows, in addition, to improve the guiding in translation of the pin 50' when the diameter thus reduced is adapted to cooperate with the contour of the useful part of the pin 50 ', as presented , specifically, in figure 23.

The support piece 52 'is fixed in the free space presented by the cross member 5' of the frame so that the closing of the hinges is not hindered while allowing the stud 50 'to cooperate with the locking element 10' .

More particularly, the support piece 52 'is fixed on the lower part 3' of the cross member 5 '.

The support piece 52 'has several through holes, two in particular, suitable for being traversed by fixing screws (not shown).

The useful end of the stud 50 'defines a male part that is suitable to fit in the female part of the locking element 10' defined by the two lugs 14A 'and 14B'.

On the other hand, as illustrated, in particular, in Figure 23, the curvature of the useful end of the stud 50 'is substantially the same, in particular, slightly more pronounced, than the curvature of the notch 28' of the workpiece. 20 'travel guidance. It follows that the retention relief defined by the notch 28 'materializes an example of a means that forms a hard point of attachment of the teat 50'.

Thus, when the blocking element 10 'is in the release configuration, the useful end of the teat 50' can remain engaged in the retaining relief due to its respective shapes, as illustrated in Figure 23.

Furthermore, according to the illustrated example, the attachment of this hook is advantageously accentuated by the impulse exerted by the second spiral spring 56 '.

Furthermore, when the blocking element 10 'is in the release configuration, it is observed that the relief formed by the thickness of the two sections of smaller thickness 12' and the retention relief do not really protrude one more than the other. It follows that the useful end of the stud 50 'can be easily released from the retaining relief by a simple pressure exerted on the semi-fixed swing 2. In fact, since the stud 50' is elastically mounted movable on the contour of the opening and since the end of the useful part of the stud 50 'is rounded, the stud 50' can pass over the retaining relief as well as over the relief formed by the thickness of the section of smaller thickness 12 ', which is located on the opening side of the semi-fixed swing 2, so that the stud 50 'is released from the hard holding point, as illustrated in Figure 24.

On the other hand, as illustrated in particular in Figure 24, the retention relief is housed, at least in part, in the groove 4 'of the traverse 9'.

Advantageously, this relief is adapted to substantially flush with the outer edges of the groove 4 'forming a proper edge of the traverse 9' of the semi-fixed leaf 2.

To this end, according to this example, the thickness of the two smaller portions 12 'of the blocking element 10', on the one hand and the thickness of the sliding guide piece 20 'on the other hand, are adapted so that the edge free of the two thinner portions 12 'and the edges of the notch 28' substantially flush with the outer edges of the groove 4 '.

It follows that, during a closing movement of the semi-fixed leaflet 2, the second retention organ can play the role of a suitable cam to follow a ramp portion defined by a proper edge of the crossbar 9 'of the semi-fixed leaflet 2 and by the retention relief.

It is understood, therefore, that, during a closing movement of the semi-fixed swing 2, in this way, the engagement of the second retention organ in the retention relief can be done smoothly.

This effect is obtained even better since this edge of the traverse 9 'naturally has an inclined portion 9A', as is the case of the semi-fixed swing 2, shown in Figure 24, which facilitates the contacting of the second retention organ with the ramp portion asf defined during a closing movement of the semi-fixed swing 2.

On the other hand, when the blocking element 10 'is in the blocking configuration, it is observed that the blocking relief formed by the thickness of the two lugs 14A' and 14B 'is more pronounced than the retention relief defined by the notch 28 'of the sliding guide piece 20', as illustrated in Figure 28. It follows that the male part defined by the stud 50 'is embedded in the female part defined by the two lugs 14A' and 14B ', which prevents the release of the pin 50 ', even when a pressure is exerted on the semi-fixed leaf 2. Due to this fact, the semi-fixed leaf 2 is locked in the closed position.

The blocking device according to the third embodiment also includes a cam 60 'intended to be integral with the mobile leaf 1 to cooperate with the control organ 16' so as to drive the blocking element 10 'towards its blocking configuration, when the semi-fixed swing 2 is in its closed position.

According to the example illustrated in Figures 26 and 27, cam 60 is an independent part of the mobile leaf 1 that is suitable for fixing on the latter in the vicinity of an area of encounter with the control organ 16.

More particularly, the cam 60 'is housed, at least in part, in a groove 71' which has the amount 81 'of the mobile leaf 1 intended to face the semi-fixed leaf 2.

According to the illustrated example, the cam 60 'has a first wing housed in this groove 71' and a second wing perpendicular to the first one housed in a groove presenting the cross member of the mobile leaf 1.

According to the example illustrated in particular, in Figures 26 and 27, the cam 60 'includes a useful part 62' rounded.

The useful part 62 'is formed in the first wing of the cam 60'.

The cam 60 'is mounted on the mobile leaf 1 so that at least the useful part 62' of the cam 60 'protrudes from the pillar 81' of the mobile leaf 1, in the vicinity of one end of this pillar 81 ', by example, the lower end.

Thus, according to this example, the useful part 62 'of the cam 60' is suitable for projecting from this stud 81 'in the direction of the semi-fixed leaf 2 when the semi-fixed leaf 2 and the mobile leaf 1 are both in the closed position.

Likewise, the blocking element 10 'of the blocking device is mounted on the semi-fixed leaf 2 so that at least the control organ 16' of this locking element 10 'is suitable for projecting from the upright 8' of the semi-fixed leaf 2 intended to be in front of the mobile leaf 1, in the vicinity of one end of this stud 8 ', for example, in the lower end of this stud 8'.

Thus, according to the illustrated example, the control organ 16 'of the blocking element 10' is suitable for projecting from this stud 8 'in the direction of the mobile leaf 1 when the semi-fixed leaf 2 and the mobile leaf 1 are both in position of closing.

It follows that the control organ 16 'is suitable for cooperating with the cam 60' when the semi-fixed leaf 2 is in its closed position, on the one hand and when the mobile leaf 1 is in a closing movement until it is closed , on the other hand.

In particular, the control organ 16 'has a ramp 17' formed at the end of the retaining element 10 'intended to be in front of the mobile leaf 1, when the semi-fixed leaf 2 is in its closed position.

In this way, the ramp 17 'is configured to cooperate with the useful part 62' rounded by the cam 60 ',

when the semi-fixed leaf 2 is in its closing position, on the one hand and when the mobile leaf 1 is in a closing movement until it is closed, on the other hand.

The cooperation between the useful part 62 'of the cam 60' and the ramp 17 'of the control organ 16' causes the blocking element 10 'to slide towards its blocking configuration during the closing movement of the mobile leaf 1, which It allows to lock the semi-fixed swing 2 in the closed position.

In the third embodiment described above, a mobile leaf 1 and a semi-fixed leaf have been shown, both comprising a hollow fence formed by two crossbars and two uprights, inside which a glass is mounted.

In the third embodiment described above, a first retention organ and a control organ, suitable for sliding fittings on the semi-fixed leaflet, have been represented, so that it can be contemplated, without leaving the scope of the present invention, to provide that be pivotal. For this, it is possible, for example, to adapt the jogger, described above in the second embodiment, to mount it on the semi-fixed swing and so that the first retaining organ of this jogger is suitable for cooperating with a teton analogous to that described in the third mode of realization.

On the other hand, in the third embodiment described above, a single locking device mounted in the vicinity of the lower traverse of the contour of the opening has been represented, so that it can be contemplated, without departing from the scope of the present invention, assembling a single blocking device, analogous to the one described above, in the immediate vicinity of the upper crossbar of the contour of the bay or simultaneously mount two locking devices on the lower and upper crossbars, respectively.

It may also be contemplated, without departing from the scope of the present invention, to mount a first locking device according to any embodiment described above on one of the two crossbars (lower or upper) of the contour of the opening, as well as a second blocking device according to another of these embodiments in the other traverse.

In the three embodiments described above, a first retention organ has been represented which comprises either two lugs or two stop walls that define a suitable female part so that a male part of the second retention organ fits into it, so that it could be contemplated, without departing from the scope of the present invention, a first retention organ that only comprises a single lug or a stop wall to define said female part and that protrudes from the front part of the blocking element to block the semi-fixed swing in the closed position. In addition, in the three embodiments described above, a semi-fixed leaf and a mobile leaf have been shown which are both mounted in a frame comprising two uprights and two crossbars, so that it can be foreseen, without departing from the scope of the present invention, a different assembly of the two hinges, as long as the semi-fixed swing is suitable to cooperate with the mobile leaf to close a gap. In particular, it could be foreseen, without leaving the scope of the present invention, a semi-fixed leaf and a mobile leaf which are mounted in a fence comprising two uprights and a single crossbar, even no crossbar. In that case, a blocking element according to the present invention (when the first variant is implemented) or a second retention organ according to the present invention (when the second variant is implemented), could be mounted directly on the contour of the opening , in the immediate vicinity of a meeting area of the swinging.
