Description

Swing shutter hinge device and swing shutter equipped with such a device

The invention relates to the field of shutters, in particular swing shutters, and in particular the field of devices for locking these swing shutters when the latter are in the open position.

The invention relates more specifically to a hinged shutter device for locking and unlocking swing shutters intended to equip a bay, such as a door or a window of a dwelling.

In known manner, a swing shutter is schematically composed of at least one flat panel, or leaf, often made of wood, PVC or aluminum, said panel being supported by hinges, at least two per panel.

Said hinges of the shutter are engaged, by their end node, or eye, in hinges composed of a shaft, corresponding to the base of the hinge, and a metal rod, themselves supported by fittings sealed in the wall of the dwelling.

The hinges allow, therefore, to fix the leaf to the axis of the hinge formed by the metal rod, on which the hinges of the shutter turn.

In the case of a hinged shutter intended to equip a window, this generally comprises a pair of panels, positioned on either side of the window, each of these panels being fixed by hinges.

Traditionally, the shutters are each held, when they are in the open position, by a blocking device with oscillating hooks or by a device with tilting hooks, such devices being sealed in the wall of the dwelling.

Whatever the hook device used to hold the shutters in the open position, leaf against the facade of the dwelling, said device is generally positioned at the level of half the width of the leaf shutter furthest from the window, in order to to ensure correct support of the leaf against the facade. Consequently, such devices are difficult to maneuver for a user located inside the dwelling.

It is then often preferable to leave the house in order to stand in front of these devices to operate them, rather than to lean out of the window. However, for shutters located on the floors of a dwelling, blocking the leaves from inside the dwelling remains mandatory.

In addition, the installation of blocking devices at the level of the facade of the dwelling can prove to be particularly delicate, it is particularly necessary to seal the device in the facade, which requires the intervention of a specialized person.

Attempts have been made, in the state of the art, to propose various blocking solutions for swing shutters.

We thus know, from the French patent application published under the number FR 2 481 350, a device making it possible to block, in the open position, the hinged shutters of a bay, intended to replace the pivoting latch traditionally fixed on the facade.

Such a device consists, on the one hand, of an orifice pierced diametrically through the eye of at least one hinge supporting each shutter, and through the cylindrical part, or metal rod, of the hinge on which said hinge pivots .

On the other hand, the locking device of document FR 2 481 350 consists of a pin, intended to be housed, in a removable manner, in said drilled hole at the level of the eye and of the cylindrical part, so to secure the node of the hinge to the cylindrical part of the hinge and to prevent the pivoting of the hinge around the axis of the hinge, when the leaf is in the open position.

The holes can be pierced along an axis parallel to the shutter when it is open, while the pin can be formed of a rigid cylindrical rod, retained on the shutter panel, by means of a chain, a ring being provided to be placed between the pin and the chain.

The document published under number FR 2 494 756 constitutes an additional application to the previous document, specifying that the end of the pin intended to be introduced into the hole has a conical shape.

These devices have the disadvantage of comprising a pin, constituting an added element, which must be fixed on the shutter and require the user to lean out to position or grasp it.

In addition, such a pin is not linked to the locking device, and can therefore become detached from it, and be misplaced.

Another disadvantage of the presence of such a pin is that it is likely to jam in the holes in the locking position, requiring the user to make a particular effort to be removed.

The international application published under number WO 02/088501 describes a device for locking a shutter hinge in rotation around the hinge on which it is mounted, thus making it possible to immobilize the shutter in the open or closed position.

We are looking here to replace a tilting lock system, fixed on the hinge, which is placed, at the time of locking, in a groove made at the bottom of the hinge, thus blocking the shutter. Indeed, for such a system to work properly, it is necessary that the lock and the groove of the hinge are perfectly aligned, the hinge sealed well perpendicular to the masonry.

We then propose a device comprising a grooved adapter ring, and adjustable in rotation before its fixing on the hinge, so that its groove is always perfectly aligned with respect to the plane of rotation of the lock.

The ring is therefore equipped with a groove, a hole and a groove, and is positioned on the bottom of the cylindrical part of a hinge, before being fixed there by means of a self-drilling screw.

French patent application FR 2 775 723 describes a similar device, making it possible to lock the rotation of the hinge of a shutter around the hinge on which the hinge is mounted, so as to make it possible to immobilize the shutter in the open position.

More specifically, in this device, a lock is mounted on the hinge with the aid of a pivot, and tilts around this pivot to come to be inserted, in the locking position, between the hinge and the hinge, thanks, d on the one hand, with a groove made on the top of the hinge loop and, on the other hand, with a machined flat on the top of the hinge.

In patent application FR 2 789 720 Another device for locking a shutter hinge in rotation is described.

This locking device makes it possible to immobilize the shutter in the open or closed position. It is more particularly made up of a grooved hinge, fixed on a shutter, intended to be mounted on a one-piece hinge, at the level of which two flats have been machined.

On this hinge is wound a lock formed by a spring steel wire, one of the ends of which can be placed in a housing located either on the top of the hinge, or on the bottom of it, thus locking the rotation of the hinge.

The lock surrounds the axis of the hinge, and forms two loops, one having a torsion spring effect, and the second serving as a handle. One of the ends of the steel wire engages in a housing created by the alignment of a groove, made in the hinge, and a flat, machined on the hinge, which locks the mechanism.

To unlock the mechanism, it is necessary to push on the large buckle, which will cause the release of the steel wire from the housing formed by the groove and the flat, and the release of the hinge.

A second flat, made on the hinge, allows the shutter to be locked in the closed position.

Such devices can be complex to develop, and/or require machining, to obtain grooves, flats, in the parts making up the swing shutter, machining which can also be complex to produce.

In order to respond, at least in part, to the drawbacks of the state of the art, it was imagined, in an inventive approach, to develop a device for locking a shutter, when the latter is in position. open, which is of simple design and use, while allowing the locking and unlocking of a swing shutter to be controlled, without having to leave the house, or to lean out of the window to reach it and maneuver.

Thus, the present invention relates more particularly to a hinged shutter device, comprising a hinge and a hinge, where said hinge comprises an eye and said hinge a nipple introduced into said eye to allow said shutter to pivot from one direction. so-called open position to a so-called closed position, and vice versa.

Said hinge device according to the present invention is more particularly characterized in that said hinge comprises a movable element in a direction parallel to the pivot axis of said flap, elastically returned, manually maneuverable by constraint of the elastic return means when said flap is in the so-called open position, while said hinge comprises, on the periphery of said eye, on the insertion side of said nipple, an indexing zone capable of receiving said movable element when said flap is in the open position, so as to ensure the blocking said flap in this position.

According to a particular embodiment of the present invention, said hinge of the hinge device comprises an eye and said hinge a nipple introduced into said eye to allow said flap to pivot from a so-called open position to a so-called closed position, and vice versa , and is characterized in that said hinge comprises an element movable in a direction parallel to the pivot axis of said flap, elastically returned, manually operable by constraint of the elastic return means when said flap is in the so-called open position, while said hinge comprises, on the periphery of said eye, on the insertion side of said nipple, an indexing zone capable of receiving said movable element when said flap is in the open position, so as to ensure the blocking of said flap in this position.

Most preferably, said movable element comprises a rod sliding in a groove coaxial with the pivot axis of said flap, the end of said rod external to said groove being provided with a gripping means and the opposite end of said rod, inside the groove being integral with an indexing finger able to slide, on the one hand, in said indexing zone on the periphery of the eye of the hinge and, on the other hand, in a hole arranged right through and perpendicular to the axis of said hinge.

Advantageously, said indexing pin is slidable in a first hole made right through and perpendicular to the axis of said nipple and, simultaneously, in a second hole made in an anchoring element in the masonry of a dwelling. , that comprises said hinge at the base of said nipple.

The indexing pin may consist, more particularly, of a key, while said elastic return means may consist of a spring.

The invention also relates to a swing shutter characterized in that it comprises a lower hinge device according to the invention and as described above.

The hinged shutter can advantageously, in addition to the lower hinge device, comprise an upper hinge comprising, like said lower hinge, a hinge and a hinge, where said hinge comprises an eye and said hinge a nipple introduced into said eye to allow said flap to pivot from a so-called open position to a so-called closed position, and vice versa, as well as an elastic return means from the so-called open position to the so-called closed position.

It is also conceivable that said lower articulation of said hinged shutter comprises, in addition to the elements already described above, an elastic return means from the so-called open position to the so-called closed position.

In addition to the advantage provided by this device and already mentioned above, which consists in preventing the user from having to lean out of the house to block the shutters in the open position, the device of the The invention makes it possible to impel the shutter to a flap movement towards its closed position, when the latter is unlocked.

Other aims and advantages of the present invention will appear during the description which will follow relating to embodiments which are given only by way of indicative and non-limiting examples.

The understanding of this description will be facilitated by referring to the attached drawings in which:

schematically represents a perspective view of a first variant of a first embodiment of a part of the hinged shutter device according to the present invention, namely the hinge of said hinge device.

schematically represents, on the one hand, a view in longitudinal section of the hinge of the articulation device of the and, on the other hand, a view of the eye of the hinge intended to pivot around the nipple of said hinge.

schematically represents another view of an articulation device conforming to that illustrated in FIGS. 1 and 2.

schematically represents a second variant of the first embodiment of the articulation device according to the present invention.

schematically shows a second embodiment of the hinged shutter device according to the present invention, the eye of the hinge intended to pivot around the nipple of said hinge being shown cutaway.

With reference to these drawings, the present invention relates more specifically to a hinge device 1 for a swing shutter.

Such a shutter traditionally comprises, among other elements, two hinges including a lower hinge 2 and an upper hinge, not shown in the attached figures. A swing shutter further comprises a lower hinge 3, visible in Figures 2, 3 and 5 of the accompanying drawings, and an upper hinge, which equip a flat panel of the shutter.

Said lower hinge 3 is provided with an eye 4, while said lower hinge 2 comprises a nipple 5 which is intended to be introduced into said eye 4. The same is true for the upper hinge, not shown, whose nipple comes engage in the eye of the upper hinge. Thus, through these hinges and hinges, the swing shutter is able to pivot from a so-called open position, in which the shutter is folded against the masonry of a dwelling, to a so-called closed position, in which the shutter is positioned in front of a bay, and vice versa.

It should also be noted that, in addition to nipple 5, a hinged shutter hinge 2 also comprises, at the base of said nipple 5, an element 6 for anchoring said hinge 2 to the masonry of a dwelling which is intended to be equipped with said swing shutter.

According to the present invention, said hinge 2 of the hinge device 1 for a hinged shutter essentially comprises a movable element 7 in a direction parallel to the pivot axis 8 of said shutter, which corresponds to the axis of the nipple 5.

This movable element 7 is linked to an elastic return means 9 and is manually operable, by constraint of said elastic return means 9, when said flap is blocked in its so-called open position.

With regard to the hinge 3 now, which is more particularly visible in Figures 2, 3 and 5, the latter is provided, on the periphery with its eye 4, and on the side of introduction of said nipple 5 into said eye 4, of an index area 10.

This indexing zone 10 has the function of receiving said movable element 7 when said flap is in the open position, so as to ensure the blocking of said flap in this position.

Thus, in a particularly interesting manner, when the hinged shutter is in the so-called open position, with the shutter blocked, the movable element 7 is raised upwards, under the action of the elastic return means 9, and engages in the indexing zone 10 arranged in the base of the eye 4 of the hinge 3, thus preventing any rotation of the said hinge 3 around the axis 8.

In a first embodiment, which is shown in Figures 1 to 4, when the user wants the shutter to pass into the so-called closed position, in front of a window in his home, he just has to manually pull said movable element 7, in the direction opposite to the return force of the elastic means 9, in other words to constrain said elastic return means 9, so as to release the indexing zone 10 from the movable element 7, and thus authorize the rotation of the eye 4 of the hinge 3 around the axis of rotation 8.

It should be noted that, very preferably, a single and unique indexing means 10 equips the hinge 3 so that the movable element 7 can slide there only when the hinged shutter is in the so-called open position. Once the hinge 3 has been rotated, said swing shutter having passed into the so-called closed position, the movable element 7 can no longer engage in the indexing means 10, which has moved under the effect of the rotation, so as to prevent the flap from also being blocked by said movable element 7 in the so-called closed position.

The swing shutter is then held in the so-called closed position in front of a window by any type of means conventionally implemented for this purpose and known to those skilled in the art, such means being operable from inside the dwelling when the shutter is closed.

In a first embodiment variant of this first embodiment, with reference to the attached figures 1 to 3, the movable element 7 of the hinge device 1 for a swing shutter according to the invention is in particular in the form of a rod 11 sliding in a groove 12 formed, preferably, coaxially with the pivot axis 8 of said flap, corresponding to the axis of the nipple 5 of the hinge 2.

A first end of said rod 11, more particularly end 11a which is external to said groove 12, in the lower part of hinge 2, is integral with a gripping means 13, the latter advantageously consisting of a handle.

As regards the second end 11b of the rod 11, opposite the end 11a, the latter is located inside the groove 12, and it is made integral, in particular by screwing, with a finger of indexing 14.

This indexing finger 14 is in particular able to slide, to pass from one position to another, in said indexing zone 10 that comprises the hinge 3, on the periphery of its eye 4, but also in at least a first drilling provided right through and crossing perpendicularly to the axis 8 of the nipple 5 of the said hinge 2, this first drilling not being visible in the figures.

Even more preferentially, said indexing pin 14, preferably in the form of a key, slides in the first hole formed right through and perpendicular to axis 8 of said nipple 5, as mentioned above. above, and, simultaneously, in a second hole 15 which is provided in the anchoring element 6 to the masonry of a dwelling, which comprises said hinge 2 at the level of the base of said nipple 5.

Such a particularly preferred embodiment is that shown in Figures 1 to 3.

Said indexing finger 14 is thus movable between two positions, a so-called locking position in which it is engaged in the indexing zone 10 of the eye 4 of the hinge 3, and an unlocking position in which it is outside of this indexing zone 10, to allow rotation of the flap.

The passage from the locking position to the unlocking position of the indexing pin 14 is done by manual operation against the action of the elastic return means 9, preferably a spring, surrounding the rod 11 in the groove 12, said means elastic return being preferably tensioned by means of a nut 16 being fixed around the rod 11 of the movable element 7, under the anchoring element 6 of the hinge 2 to the masonry of a dwelling .

It should also be noted that said indexing pin 14, when it is in the form of a key, may comprise a machined part 17, visible on the , in order to prevent the flap from being prevented from reaching its so-called open position.

On the of the attached drawings is shown a second alternative embodiment of this first embodiment, just as advantageous, of the flap hinge device of the invention, in which the movable element 7, still in the form of a rod 11 sliding in a groove 12 arranged, this time, parallel to and offset from the pivot axis 8 of said flap.

The end 11a of the rod is integral with a handle 13 while the second end 11b of the rod 11 is integral with a key which slides in the indexing zone 10 that comprises the eye 4 of the hinge 3 and in a hole in the hinge 2, in particular the nipple 5 and the anchoring element 6 of the hinge 2.

In a second exemplary embodiment of the hinge device 1 of the hinged shutter according to the invention, which is particularly preferred and described now with reference to the , the indexing zone 10 is made in a ring 18 independent of said hinge 3 and fixedly secured thereto.

The attachment of said ring 18 to said hinge is preferably carried out by means of a needle screw 19.

Said ring 18 engages on the nipple 5 of the hinge 2 and the base 181 that this ring 18 comprises is inserted between the base 6 of the hinge 2 and the eye 4 of the hinge 3. The said base 181 of the ring 18 is surmounted by a sleeve 182, of smaller diameter than that of the base 181, said sleeve 182 filling a void between the nipple 5 of the hinge 2 and the eye 4 of the hinge 3, so as to prevent it there is play between said eye 4 and said nipple 5.

In this second embodiment, said movable element 7 still comprises a rod 11, sliding in a groove which is coaxial with the pivot axis 8 of said shutter.

The end of said rod 11 which is outside said groove and is located at the top of nipple 5 is provided with a pressure means 20, advantageously in the form of a push button.

In this embodiment, the elastic return means 9, preferably consisting of a spring, is positioned between said pressure means 20 and the top of the nipple 5 of the hinge 2.

Most preferably, a bellows, or flap, can surround the spring to protect it. Such a means of protecting the spring is however not represented on the .

The second end of said rod 11, the one which is inside the groove and not visible on the , is secured to an indexing pin 14. The latter is capable of sliding, on the one hand, in said indexing zone 10 on the periphery of the base 181 of said ring 18 which is secured to the hinge 3 by engagement in said nipple 5. On the other hand, said indexing finger 14 slides in a bore formed right through and perpendicular to axis 8 of said hinge 2.

Even more particularly, and as illustrated in the , said indexing finger 14 is slidable in a first bore formed right through and perpendicular to the axis 8 of said nipple 5 and, simultaneously, in a second bore 15 formed in the anchoring element 6 to the masonry of a dwelling, which said hinge 2 comprises, at the base of said nipple 5.

Just as for the first embodiment, said indexing finger 14 can consist of a key.

In this embodiment, in the relaxed position, the elastic return means 9 in the form of a spring pulls the indexing finger 14 upwards, so that the latter is engaged in the indexing zone 10 formed on the periphery of base 181 of said ring 18 secured to hinge 3, thus preventing any rotation of said hinge 3 around axis 8.

When pressure is applied to said push button 20, spring 9 is compressed and indexing finger 14 is lowered.

Just as in the first embodiment described above, said indexing finger 14 is thus movable between two positions, a so-called blocking position in which it is engaged in the indexing zone 10 of the eye 4 of the hinge 3, and an unlocking position in which it is outside this indexing zone 10, to allow rotation of the shutter.

The passage from the locking position to the unlocking position of the indexing finger 14 is done here by manual operation against the action of the spring 9, surrounding the rod 11, at the top of the nipple 5 of the hinge 2.

The present invention also relates to a swing shutter comprising a lower hinge device 1 having the characteristics of the first or second embodiment which have been described above.

In an even more particular way to the invention, such a flap shutter comprises, in addition to the aforementioned lower joint, an upper joint, not shown in the figures, and comprising, like the lower joint, a hinge and a hinge .

Traditionally, at this upper joint, said hinge comprises an eye, and said hinge a nipple, intended to be introduced into said eye to allow said flap to pivot from a so-called open position to a so-called closed position, and vice versa.

According to a particular characteristic of the invention, said nipple of the upper hinge comprises an elastic return means from the so-called open position to the so-called closed position.

More particularly, said nipple of the upper hinge is surrounded by an elastic return means in the form, advantageously, of a spring, one of the ends of which is fixed in a housing formed either at the base of the nipple, or in the anchoring element of the upper hinge to the masonry of the dwelling.

The second end of the elastic return means is fixed in a housing formed in the eye of the upper hinge, so that the said elastic return means is put under tension when the hinged shutter is open.

Thus, when the lower hinge device 1, in accordance with the invention, is unlocked by the user wishing that the hinged shutter fitted with said device 1 passes from its so-called open position to its so-called closed position, the elastic return means of the upper articulation which also equips, preferably, said flapping shutter will cause an automatic flap of said flapping shutter towards its closed position.

Such elastic return means causing the flap in the closed position of the flap can also be fitted to the lower joint of the flap.

It emerges from the foregoing that the invention described above not only has the advantage of proposing a simple solution for allowing a swing shutter to be blocked in its so-called open position, easily maneuverable by a user from the inside his home, and without the risk of misplacing an added element of the device, but also the possibility of giving the shutter a flap movement when it is unlocked.

This facilitates the transition from the so-called open position of the leaf shutter to its so-called closed position, by allowing an automatic return of said shutter to its closed position.

It should also be noted that the hinge device 1 for a swing shutter according to the invention also makes it possible to adjust the position of the cylindrical part of the hinge, according to a particular angle with respect to the open shutter, which makes it possible to adapt said device 1 to facades forming an angle less or more than 180° with the window.
