THERE IS SLIDING SHUTTER.

FR 3 057 010 - A1 (£ /) This sliding shutter comprises a panel (6) and means for guiding said panel (6) to guide it between a closed position and an open position.

These guide means include:

- an axis (16) extending parallel to the panel (6),

- a guide rail (10) fixed to the panel (6) with an orientation substantially perpendicular to the axis (16),

- a carriage (12) slidably mounted on a guide rail (10),

- a link arm (14) fixedly mounted on the axis (16) and on a carriage (12),

- a guide path in a plane perpendicular to the panel, and

- a follower device (46.50) engaged with the guide path and connected to the panel (6).

The panel (6) in its open position is parallel to the panel in its closed position but offset from the closed position by being further from the axis (16).

The present invention relates to a sliding shutter.

The field of the present invention is thus that of shuttering a window or the like. In a building, to let in daylight, it is known to make an opening and to provide it with a window which makes it possible to close said opening in a sealed manner (air and water) while letting the light pass.

It is then known to provide such an opening with at least one external flap. The latter then has the function of providing shade and / or to opacify the opening, to protect the joinery from the wind and bad weather and also form an additional barrier against break-ins.

There are several types of shutters. There are, for example, roller shutters, pivoting shutters and sliding panel shutters.

The present invention relates more particularly to sliding shutters. Such shutters are generally slidably mounted on at least one rail which is fixed projecting on the facade of the building above and / or below the corresponding opening. The sliding shutter generally remains projecting from the front both in its closed position and its open position. Therefore, it has several drawbacks and in particular, on the one hand, that it almost always remains one day between the shutter and the opening of the facade even in the closed position of the shutter and, on the other hand, that the barrier formed by such a shutter vis-à-vis a break-in is not very dissuasive because the shutter offers a low resistance to tearing. On the other hand, the sliding shutter is generally easier to handle: it can be more easily opened and closed from inside the building. In addition, opening and closing operations are less sensitive to wind.

The present invention therefore aims to provide a sliding shutter which has the advantages of the sliding shutter and which is therefore easy to handle from inside the building but which does not have at least some drawbacks. Advantageously, a sliding shutter according to the invention will ensure a significant degree of protection against break-ins. Preferably, it will also make it possible to properly seal the corresponding opening and to greatly limit the possibility of outside light entering through this opening.

The present invention also aims to provide a sliding shutter which is easy to mount in an opening.

To this end, the present invention provides a sliding shutter comprising a panel and means for guiding said panel to guide it between a closed position and an open position.

According to the present invention, the guide means comprise:

- an axis extending parallel to the panel,

- at least one guide rail fixed to the panel with an orientation substantially perpendicular to the axis,

- a carriage mounted sliding on a guide rail,

a link arm, one end of which is fixedly mounted on the axis and the other end of which is articulated on a carriage,

a guide path extending in a plane substantially perpendicular to the panel, and

- a follower device engaged with the guide path and connected to the panel, so that the panel in its open position is parallel to the panel in its closed position but offset from the closed position by being further from the axis .

Thanks to these guide means, it is possible to fit the panel into the opening with which it is associated. In this way, it allows on the one hand to better seal the opening and on the other hand to offer less grip during an attempted break-in.

To facilitate the mounting of the sliding shutter, the axis is advantageously fixed to a lateral profile by means of bearings. It is then easier to mount the lateral profile on a vertical upright of the opening for which the shutter is intended rather than to mount the axis in said opening. For aesthetic reasons, it is then provided that a cover profile is fixed, for example by snap-fastening, to the side profile, the axis being between the side profile and the cover profile.

To facilitate the operation of the sliding shutter, in particular at the opening, it is advantageously provided that a carriage is provided with a stop preloaded by at least one spring and retractable, and that the corresponding guide rail comprises a buttress. Thus, at the opening, when the stop comes against the abutment, a resistant force is created which forces the rotation of the link arm in its correct position. In an alternative embodiment, one could for example provide that a spring is mounted coaxially on the axis and comes to prestress the link arm in its position corresponding to the open position of the panel.

According to an alternative embodiment, the link arm has for example an angled shape.

To ensure good guidance, the guide path preferably has two facing grooves, and the follower device comprises a roller partially housed in each of the two grooves. Thus, guidance is provided on both sides of the roller. In this embodiment, to allow the roller to freely follow the guide path, provision is made, for example, for the roller to be mounted on a rolling axis, said rolling axis being mounted on a support having at least locally a circular peripheral shape and disposed in a housing so as to be able to pivot in said housing relative to a pivot axis perpendicular to the rolling axis.

So that the panel remains in its intermediate positions substantially parallel to its open position or to its closed position, the guide path preferably has, on the side of the axis, a rectilinear shape parallel to the panel and ends on the side opposite the axis. by a curved shape having a curved shape with an inflection point.

To limit the bending forces, it is advantageously provided that the sliding shutter further comprises a panel support wheel in the open position, this support wheel being substantially in the middle position of the panel when the latter is in the open position.

According to a preferred variant, the sliding shutter as described above, to improve its security, further comprises a latch and a keeper, the latter being intended to be fixed to a fixed element external to the shutter, the lock then coming to cooperate with the keep to prevent movement in a direction perpendicular to the panel when the panel is in the closed position. In this way, an individual trying to open the shutter by acting on the panel from the outside will be prevented from acting thanks to the cooperation of the lock with the strike.

When such a locking is provided, there is advantageously a mechanism for actuating the bolt with an actuating lever extending substantially parallel to the panel and connecting means between the actuating lever making it possible to transform a movement of the lever d actuation towards the panel in a movement of withdrawal of the latch relative to the strike. Indeed, with such a mechanism, in the same movement you can act on the latch to open it and initiate the opening of the corresponding panel. These connecting means comprise, for example, a prestressed tie rod by a spring extending substantially parallel to the panel, the tie rod being connected, on the one hand, to the bolt and, on the other hand, to one end of an articulated arm having a elbow in contact with the actuating lever, the other end of said arm being mounted articulated on a fixed axis relative to the panel. Other connecting means can be envisaged, with for example toothed sectors which come to mesh. By providing the actuation lever and the lock each with a toothed sector, possibly providing one or two intermediate toothed wheels, it is also possible to retract the lock by pushing on the actuation lever.

The present invention also relates to a sliding shutter as described above and which comprises two panels arranged symmetrically so that when the panels are in the closed position, they are side by side in the same plane. In this closed position, the sliding shutter is preferably recessed and flush with the edges of the opening that said shutter comes to close.

Details and advantages of the present invention will become more apparent from the description which follows, given with reference to the appended schematic drawing in which:

FIG. 1 illustrates a portion of a facade 2 in which an opening 4 is produced, equipped for example with a window not shown. This opening 4 is also provided with a flap which has two panels 6. To better illustrate the invention, a first panel 6, on the left in the figure, is illustrated in its closed position while the second panel 6, on the right on Figure 1 is illustrated in the open position.

As shown in Figure 1, the panel 6 in the closed position is located inside the opening 4 while the panel 6 in the open position is outside the opening The two panels 6 illustrated are all the two oriented in parallel planes, which will be assumed thereafter vertical, but offset by a few centimeters (of the order of ten centimeters, that is to say for example between 5 and 30 cm, this measurement being of course carried out perpendicular to the planes of the panels 6).

We also note in Figure 1 the presence of a support roller 8 (there are two but one of them is hidden by the open panel 6) which is fixed on the front 2.

If the view of Figure 1 is considered a front view, Figure 2 is a rear view. In this view, only the sliding shutter has been illustrated, without the facade. FIG. 2 illustrates as a whole the mechanism which makes it possible to pass a panel 6 from its open position to its closed position, and vice versa.

In the preferred embodiment illustrated in the figures, each panel 6 is provided on one side, hereinafter called the rear side, with two guide rails 10 mounted parallel to one another. As mentioned above, each panel 6 is assumed to be in a vertical position. The guide rails 10 extend in horizontal direction. These guide rails 10 are for example made from an aluminum profile and here extend over the entire width of the corresponding panel 6.

Each guide rail 10 receives a carriage 12 which is connected by a connecting arm forming a bracket 14 to a vertical axis 16 fixed on a lateral profile 18 (also vertical).

The carriage 12 has a shape adapted to that of the guide rail

10. The latter has for example a C-shaped shape. The carriage 12 has for example a U-shaped base 20 located outside of the guide rail 10 (cf. FIGS. 5 or 6 for example). The bottom of the base 20 then carries on its face opposite the branches of the U two pads 22 of shape complementary to that of the guide rail and which are then guided in the profile in C. Stops 24 ensure the end of travel of the carriage 12 relative to its guide rail 10.

The branches of the U of the base are used to connect the carriage 12 to a bracket 14. The connection between the bracket 14 and the carriage 12 is made for example using a bolt 26 which then serves as an axis of vertical pivoting between the carriage 12 and the bracket 14. The bracket 14 is oriented in a horizontal plane.

The bracket 14 is also connected to the vertical axis 16 (see for example Figure 9). The end of the bracket 14 opposite the carriage 12 is provided for this purpose with a section of tube 28 which extends vertically. The tube section 28 is for example welded to the square 14. The vertical axis 16 is a cylindrical axis (tubular or solid) and the tube section 28 is fitted on the vertical axis with an adjustment for guiding in rotation of the tube section 28 and the bracket 14.

Figures 3 and 4 show the environment of the vertical axis from below. In these figures, there is a bearing 32 which allows the fixing of the vertical axis 16 on a lateral profile 18. As illustrated in Figure 2, four bearings 32 are provided for each vertical axis 16. These bearings 32 are each time arranged above and below a section of tube 28 and thus also ensure the positioning of the brackets 14 on the vertical axis

16. Each bearing 32 has two tabs 34 which are fixed on the corresponding lateral profile 18. The latter is intended to be fixed on a vertical edge of the opening 4. It has for this purpose a flat base 36 as can be seen in FIGS. 3 and 4.

A cover profile 38 covers the vertical axis 16. It is fixed by snap-fastening on the corresponding side profile 18. While the side profile 18 is made for example of metal, preferably aluminum, the cover profile 38 can be made of synthetic material (PVC or other).

Note also in Figures 3 and 4 for each panel 6 the support roller 8. The latter is mounted on a housing 40 in which there is a bearing. When the corresponding panel 6 is in the open position (FIG. 4), the support roller 8 is located under the panel 6 substantially in the middle position relative to the panel 6.

The sliding shutter illustrated in the drawing thus comprises two lateral profiles 18 which are intended to be fixed on the lateral vertical walls of the opening 4. These two lateral profiles 18 are connected at the top by a "lintel" connecting the two ends upper side profiles 18. This lintel has two guide profiles 42 between which takes place a cassette 44. These elements form an upper guide path described in more detail below. This guide path cooperates with the panels 6 as shown in particular in FIG. 6.

Each panel 6 has on its rear face a guide arm 46 located, on the one hand at the upper edge of the corresponding panel 6 and, on the other hand, on the side of the panel 6 opposite the vertical axis 16 when the panel 6 is in its closed position. The aim of the guide arm 46 is to carry a follower device which cooperates with the guide path in order to guide the panel in cooperation with the brackets 14.

The follower device is shown in more detail in FIG. 7. This device is mounted in a recess 48 produced in the guide arm 46. It comprises a roller 50 mounted on a rolling pin 52. The latter is mounted in a support 54 kept prisoner with a degree of freedom in rotation between a lower plate 56 and an upper plate 58.

The lower plate 56 is substantially symmetrical to the upper plate (the difference lies in particular in the fact that one plate receives screw heads and the other nut). Each plate thus has two opposite outer edges 60 to come to rest on two opposite edges of the recess 48. A shoulder 62 associated with each edge allows positioning of the plate in the recess 48. Each plate also has a central shouldered hole 64 to receive the support 54. The latter has on its peripheral edge circular portions to cooperate with the shouldered central holes 64 of the lower plate 56 and of the upper plate 58. Thus, the support 54 can freely rotate about an axis perpendicular to the guide arm 46. The lower plate 56 is fixed to the upper plate 58 using two bolts 66. The assembly of parts is dimensioned so that when the whole is mounted in the recess of the arm of guide 46, the roller 50 projects beyond the outer surface of the lower plate 56 and the upper plate 58.

The roller 50 is intended to come to roll in the guide path produced in the lintel of the sliding shutter. This guide path is rectilinear in the guide profile 42 which extends each time from a side profile 18 in the direction of the other side profile 18. The two guide profiles are connected by the cassette 44 in which the path guidance extends.

As can be seen in FIG. 8, each guide profile 42 has a flat upper face 68 intended to come against the upper wall of the opening 4. As illustrated, the guide profile also has two grooves 70 facing each other. opposite to form a portion of the guide path. The dimensions of the roller 50 are adapted to the distance separating the two grooves 70. The two grooves 70 are separated from each other by a lateral slot allowing the passage of the guide arm 46.

The cassette 44 is made in two parts, an upper part and a lower part. In FIG. 6, the lower part of the cassette is removed to better show the follower device. These two parts of the cassette 44 are for example made of a molded synthetic material while the guide profiles 42 may be aluminum profiles.

Within the cassette 44, the guide path extends in the form of two facing grooves, one made in the upper part of the cassette 44 and the other in the lower part of the cassette 44. This path is no longer straight but has a curved shape with an inflection point. In the guide sections 42, the guide path is on the side of the panel 6. In the cassette 44, the guide path passes from the side of the cassette close to the panel 6 to the opposite side.

The assembly formed by the lateral profiles 18, the guide profiles 42 and the cassette 44 are assembled so as to form only one coherent U-shaped assembly. This assembly forms a "self-supporting" frame which carries all the elements of the sliding shutter. To stiffen this structure before mounting in an opening 4, one can provide a connecting profile between the lower ends of the side profiles 18 so as to form a rigid frame. This frame can easily be transported with the entire sliding shutter. For mounting the shutter, simply position the frame in the opening, remove the lower connection profile and come and fix the side profiles 18 and the "lintel" on the side uprights and the upper edge of the opening .

FIG. 9 shows in more detail the elements in relation to a guide rail 10. This is here the lower guide rail 10 of a panel 6. Here we notice on the carriage 12 the presence of a housing 72 and on the guide rail 10, on the left of Figure 9, the presence of a cam 74. The housing 72 contains a mechanism which is illustrated in Figure 10. The purpose of this system is to control the orientation of the 'square 14 relative to the axis 16 and / or to the panel 6 when opening the latter.

The mechanism comprises a double lever 76 pivotally mounted about a vertical axis 78 and this double lever comprises a first arm 80 and a second arm 82. A first spring 84 acts by means of a finger 86 on the first arm 80 while a second spring 88 acts on the second arm 82.

This mechanism comes to cooperate with the cam 74. When the case 72 with this mechanism moves in one direction relative to the cam 74, the cam 74 forms a stop then allows the passage of the case while in the other direction, the case 72 comes to "slide" on the cam 74.

In FIG. 10, if the cam 74 moves relative to the mechanism in the direction indicated by the arrow 90, the cam 74 comes to bear on the second arm 82. The latter is held in position by the action of the first spring 84 on the first arm 80. When the force increases, the first spring 84 is compressed. The double lever 76 pivots until it allows the housing 72 to pass. Once the housing 72 passes in front of the cam 74, the finger 86 under the action of the first spring 84 released returns the double lever 76 to its rest position.

During a movement in the opposite direction, when the second arm 82 comes into contact with the cam 74, the double lever 76 pivots against the action of the second spring 88. The latter is a leaf spring which simply the purpose of coming to recall the double lever 76 in its rest position and which is therefore dimensioned so that the resistant force during the passage of the housing 72 in front of the cam 74 is negligible (being for example less than the friction forces during panel movement 6).

This housing 72 / cam 74 assembly constitutes a part of a preferred embodiment of the sliding shutter described here. FIG. 11 illustrates another embodiment of control means acting on the system to obtain a good positioning of the bracket 14 during an opening / closing operation of a panel 6. In this variant embodiment, a spring 30 is mounted coaxially with respect to the vertical axis 16 and comes to prestress the tube section 28 in its position illustrated in FIG. 11, that is to say that the bracket 14 connected to the tube section 28 is prestressed in its position corresponding to the open position of the corresponding panel 6. The bracket 14 then preferably comes into this position and leaves it when the guide means force it to do so.

Figures 12 to 14 illustrate an optional locking system for the sliding shutter described.

The locking system comprises a locking mechanism which cooperates with a keeper 92 which can be fixed directly to a vertical lateral edge of the opening 4, between the lateral profile 18 and the panel 6. This keeper comes to cooperate with an articulated lock 94 and controlled by levers and a spring.

FIG. 12 shows in perspective the locking mechanism and a distinction is made between the keeper 92, the lock 94 which cooperates with the keeper, an actuation lever 96 and a cover 98.

Figure 13 corresponds to Figure 12, the cover 98 having been removed. We then notice a chassis comprising a bottom plate 100 and two side walls 102 extending perpendicularly to and from the bottom plate 100, the two side walls 102 being arranged in parallel opposite one of the other. The bottom plate 100 is fixed to the corresponding panel 6 and the side walls 102 are oriented perpendicular to the vertical lateral edge of the opening 4 which carries the keeper 92.

Figure 14 is a sectional view along the section line XIV-XIV of Figure 13 which illustrates the locking mechanism. The latter comprises, in addition to the parts already mentioned, in particular a tie rod 104 prestressed by a spring 106 and connected to an articulated arm 108.

The tie rod 104 is a rod slidably mounted on bearings 110 (here, three bearings 110). At one of its ends, the tie rod 104 is connected to a connecting rod 112 which is itself articulated on the bolt 94. On the side of the bearings 110 opposite the connecting rod 112, the tie rod 104 is connected to one end of the articulated arm 108. The other end of the latter is pivotally mounted on an axis 112 fixed relative to the side walls 102. Between its two ends, the articulated arm 108 forms an elbow 114 which comes to bear on an inner face of the actuating lever 96. The latter is itself pivotally mounted about another axis 116 also fixed relative to the chassis of the locking mechanism. The axis 116 is disposed substantially at the end of the actuating lever 96 opposite the latch 94. The latter is also pivotally mounted around a third axis 118 fixed relative to said chassis.

As is clear to a person skilled in the art in FIG. 14, in the rest position the locking system keeps the latch 94 in the locked position and the actuation lever 96 is in a position remote from the bottom plate 110. If a user comes to press the actuating lever 96 in the direction of the bottom plate 110 (or of the panel 6), it acts on the elbow 114 by opening the angle formed by the articulated arm. The axis 112 on which one end of the articulated arm 108 is mounted being fixed, the other end of the articulated arm 108 moves. This end being linked to the tie rod 104, it acts on the latter. By means of the connecting rod 112, the tie rod 104 then controls the pivoting of the latch 94 about its axis 118 in a direction which makes it escape from the keeper 92.

The operation of this sliding shutter is then as follows.

If the panel 6 is in the closed position, it is in the opening 4 inside of it. Advantageously, it comes to bear against the lateral profiles 18 and the lintel of the shutter.

To bring the panel to the open position, first remove it from the opening before sliding it outward beyond the opening, parallel to the front. It is therefore thus first of all necessary to release the edge of the panel located on the side of the lateral profile 18. To release it, it suffices to push it outwards, exerting a force substantially perpendicular to the plane of the panel 6.

If the panel 6 is provided with a locking device as illustrated in more detail in FIGS. 12 to 14, it is also necessary to unlock the device. In fact, the keeper 92 prevents the passage of the latch 94. The unlocking takes place in the same pressing movement perpendicular to the plane of the panel 6. In fact, it suffices to exert this pressing on the actuating lever 96 , preferably opposite the axis 116, to unlock the locking system and release the shutter out of the opening which it closes (or closed).

Under the effect of this action by the user, the brackets 14 begin to pivot around the vertical axis 16. On the opposite side of the panel, the follower device, in particular the roller 50, begins to move in the guide path . The shape of this path is such that the panel 6 always remains substantially parallel to the facade 2. Thus, by simply pushing on the panel 6, it leaves the opening and initiates a translational movement releasing it laterally outward from opening 4 (to the left or right depending on the panel in question).

The vertical edge of the panel 6 remote from the brackets 14 is guided by the guide path and the follower device. The other vertical edge is in particular guided by the brackets 14. For good guidance of the panel 6, it is necessary to ensure that when the follower device leaves the cassette 44 to cooperate with the guide profile 42, then the square 14 is substantially in the position illustrated in FIG. 4, that is to say that it has pivoted about 90 ° relative to the closed position of the panel 6.

In an embodiment corresponding more particularly to Figures 9 and 10, the carriage 12 is blocked in its movement relative to the guide rail 10 to force the bracket 14 to pivot. As explained above, when the bracket 14 is in position, the second arm 82 which cooperates with the stop formed by the cam 74 is pivoted to retract and thus allow the translational movement of the carriage 12 relative to the rail to continue. guide 10. In this case, it is sufficient to have a single housing 72 with the mechanism illustrated in FIGS. 9 and 10 per panel 6.

In the variant of Figure 11, the springs 30 help the brackets 14 to rotate 90 ° and quickly take their position corresponding to the position of the open panel. When the brackets 14 have pivoted 90 °, the roller 50 is located substantially at the junction between the cassette 44 and the guide profile 42. It is then sufficient to push the panel 6 laterally towards the outside of the opening 4.

In one or other of the embodiments, at half-opening, the panel 6 comes to rest on the support roller 8 preventing the panel 6 from bending. The latter is then perfectly guided to its fully open position ( translational movement parallel to the corresponding facade).

Panel 6 is closed by acting in the opposite direction. The panel 6 is first of all pulled towards the inside of the opening by exerting a force substantially parallel to the facade 2. When the roller 50 arrives at the level of the cassette 44, the panel 6 initiates an inward movement of the opening 4. It is then necessary to pull the panel 6 inwards, perpendicular to the panel 6 to finish bringing it into the opening 4 and bring it into its closed position.

When the panel 6 is equipped (optional) with a locking system as illustrated in particular in FIGS. 12 to 14, then at the end of the closing, the lock 94 comes to engage under the keeper 92 without any particular action. It can be seen in particular in FIG. 14 that the latch 94 has an overall shape corresponding to a circular cylindrical sector and that it comes to cooperate with the keeper 92 by a flat surface 120 corresponding substantially to a radius of the cylinder during the reentry movement of the panel 6 in the opening 4. Thus, the latch 94 is gradually pushed in rotation about its axis 118 (in the trigonometric direction in FIG. 14) when the panel 6 moves in the direction indicated by the arrow 122. On the other hand , if the panel 6 is pushed in the opposite direction without acting on the latch 94, the rounded surface 124 abuts against a corresponding surface of the keeper 92. The angle between the surface of the keeper facing the lock and the tangent to the lock facing the strike, as illustrated in FIG. 14, is an acute angle so that if the lock is pushed (without action on the actuation lever 96) on the strike, it tends to turn ( figure 14) clockwise and thus further prevent movement.

The sliding shutter presented above makes it possible to close an opening with greater security than the sliding shutters of the prior art. Indeed, in the closed position, the panel (s) of the shutter is (are) inside the opening and offers (s) less grip for a forced entry.

The flap presented above also allows good concealment of the opening with which it is associated. It is even possible to provide a peripheral joint, at least on three sides, to limit the entry of daylight.

The proposed shutter has an open "frame" with only three sides. A fourth side can of course also be envisaged. However, as it sometimes happens that the edge of a window is inclined, the fact of not providing a lower edge to the frame of the shutter makes it easier to adapt to any type of window and therefore corresponding openings.

We also note that the assembly of the shutter is easy. All the elements being mounted on a U-shaped structure, it suffices to position the structure in the opening by wedging it before fixing the elements of the structure on the periphery of the opening. There remains just the support wheel to position and fix.

Of course, the present invention is not limited to the preferred embodiment described above and shown purely by way of non-limiting illustration in the drawing and the variants mentioned. It also relates to any variant within the reach of the skilled person in the context of the claims below.
