Description

STAINLESS STEEL SUPPORT

The invention relates to an anchoring device on a support of a unitary assembly forming a awning; an installation equipped with such a device; as well as a method of mounting a unitary assembly forming a blind, using this device.

The technical field of the invention is therefore that of blinds, awnings, tents and the like, comprising a protective fabric, in particular against the sun and / or bad weather.

The canvas can be either wrapped at least in part around a tree so that it is retracted, or more or less unwound over a space that one wishes to cover and protect.

Among the canvas blinds, certain blinds commonly called "banner" are presented in the form of a unitary assembly.

Such an assembly includes the fabric winding shaft, the fabric itself, at least two hubs for guiding the winding shaft in rotation, and at least two articulated arms, respectively near one guide hubs.

Sometimes the unitary assembly is combined with a protective casing for the fabric and its winding arrangement, and possibly only articulated arms.

Such a blind is intended to be fixed on a support, for example a wall or a ceiling, or even a supporting structure such as a frame, a building or a frame. One and generally two anchoring devices provide this fixing.

The term "store" here designates this type of structure.

Documents US-1,943,739; FR-2,223,542; FR-95 850; ES-232 953; FR-2,562,145; EP-538,151; EP-499,777; FR-2,707,332; and EP-593 389 in particular, relate to this technical field. Their teaching is integrated here.

The structures proposed so far pose various problems.

In particular, their assembly is long, complex, and requires a large workforce.

In general, the anchoring of a blind requires after mounting the anchoring devices on the support, to engage inside a closed bearing of one of the anchoring devices, one of its ends according to the winding direction of the fabric.

Such an engagement is said to be "swelling".

It is only then that its second end is made integral, also with threading, of another anchoring device.

During assembly, adjustment and final anchoring, it is often necessary for one or more operators to support or move the blind. The same goes for anchoring devices. This is tedious, especially when adjusting the inclination, which must be determined with the canvas unrolled. In fact, it is frequent that the tilt adjustment obtained is not identical for the two ends of the blind.

Due to the swelling, it is difficult to produce "reversible" elements, which can either be used at one or the other end of a blind.

Similarly, the "modularity" of a blind is limited, namely the possibility of adding to one basic unitary assembly, one or more optional elements, as required.

In known structures, the inclination adjustment and the locking in position of the arms are ensured by common means, for example a gear or screws displaceable in holes in arcs of a circle.

However, the adjustment forces which correspond to the forces generated when the fabric is rolled up are much lower than the efforts to maintain the blind in the use position.

Also, if the same means combine these two functionalities, these means are undersized and / or the dimensions of the blind are limited.

The object of the invention is inter alia to overcome the drawbacks mentioned above.

To this end, a first object of the invention relates to an anchoring device on a support such as a wall. or ceiling, of a unitary assembly forming a blind with arms and a rollable fabric; the device comprising means for holding and locking the unitary assembly in a position chosen from a plurality of possible Dositions which each correspond to an inclination of the arms and of the unrolled fabric; and a console whose holding and locking means are integral, intended to be rigidly fixed on the support.

The holding and locking means include:

- A receiving cradle, able to be placed in an open state or in a closed state, and arranged so that in the open state is provided a radial passage for removal without threading of the unitary assembly in the receiving cradle;

- Indexing means intended to be brought into engagement with the unitary assembly in order to define the position chosen from the plurality of possible positions, as soon as it is deposited in the cradle in the open state, and during the transition to the state closed ;

- And a locking mechanism, separate from the indexing means, and provided to maintain the unitary assembly in position in the cradle in the closed state, substantially independently of the indexing means.

According to one characteristic, the locking mechanism comprises a clamping flange, able to take up the efforts of indexing and holding by friction. According to another characteristic, the locking mechanism comprises a surface of the console, the latter being generally symmetrical, with respect to a median plane perpendicular to the winding direction.

According to one example, the locking mechanism comprises at least one screw, intended to be made integral on the one hand with the console and on the other hand with a movable part of the locking mechanism. This screw is arranged so as to be reversible.

In this example, the locking mechanism and the console at least partially define the receiving cradle.

According to one embodiment, at least part of the receiving cradle is rotatably mounted on the console, between the open state and the closed state.

This part of the receiving cradle is mounted for rotation about an axis substantially perpendicular to a general plane of the cradle, for example over substantially a quarter turn between the open state and the closed state. It has a plane of symmetry perpendicular to its axis of rotation.

One can also provide that the cradle is at least partially slidably mounted on the console, between the open state and the closed state.

According to one characteristic, the console comprises at least one stop, capable of immobilizing a mobile part of the cradle and / or of the locking mechanism, in the open state. In one example, the console comprising a bearing face intended to be placed against the support, a mobile part of the cradle is articulated on the console so as to be extended substantially perpendicularly or parallel to the bearing face of the console, in the open state.

According to another characteristic, the receiving cradle comprises a movable part shaped so that in the open state, it allows the temporary support of the unitary assembly forming a blind on the device.

In one example, the receiving cradle has, in the closed state, a general interior shape of a cylinder with a substantially circular section.

cnαcpae constituent, of the device comprises at least one plane of symmetry, for example a plane substantially parallel to the radial removal passage formed in the open state, and therefore perpendicular to the winding direction, so that the device is generally reversible.

According to one characteristic, the cradle at least partly comprises the indexing means.

These indexing means are, in one example, at least partially arranged on the locking mechanism.

According to one embodiment, the indexing means are at least partially arranged on a movable part of the cradle, such as a flange. And the indexing means comprise at least one projecting and / or concave shape, such as toothing, intended to cooperate with at least one shape complementary to the unitary assembly forming the blind.

In one example, the indexing means comprise at least one graduation arranged so as to determine, when the holding means are in the open state, the inclination given to the unitary assembly forming the blind once the holding means in the closed state.

Another object of the invention relates to an installation comprising at least one anchoring device as mentioned above, and a unitary assembly forming a blind with rolling fabric and articulated arms.

The unitary assembly comprises: a fabric winding shaft, extended in a winding direction; - two hubs for guiding the winding shaft in rotation, at each of its ends in the winding direction; and

- At least two deployment arms of the fabric, respectively secured to a guide hub.

In addition, the unitary assembly comprises at least one external bearing, capable of being received, via the deposit passage, by the cradle of the anchoring device, and immobilized in a position chosen inside the cradle by the mechanism of locking; and

- At least one additional form of indexing, distinct from the scope, and capable of being engaged with the means of indexing the anchoring device, at least in the open state. According to one embodiment, at least one bearing surface is at least partially arranged on a hub.

In the case where the unitary assembly comprises a body for protecting the rolled up fabric, the external bearing of the unitary assembly is, according to one characteristic, at least partially arranged on the body, possibly at a distance from the hubs, in the direction winding.

According to one characteristic, the complementary shape intended to cooperate with the indexing means of the anchoring device is at least partly on a hub.

According to another characteristic, the complementary shape is at least partly on a body for protecting the rolled up fabric.

According to one embodiment, the complementary shape of the unitary assembly comprises a semi-circular toothing, and the indexing means of the anchoring device comprise at least one tooth, and for example less than ten neighboring teeth.

According to one embodiment, the complementary forms intended to cooperate with the indexing means of the anchoring device are extended substantially flush with the bearing surface, without projecting from it.

One embodiment comprises a unitary assembly forming a blind provided at each of its ends in the winding direction of the fabric, with a guide hub in rotation, each hub having a shape complementary, an external bearing and articulation royens of a deployment arm, on this hub.

In this example, each guide hub has symmetry with respect to a plane parallel to the winding direction and to an arm deployment plane, so as to be reversible.

According to one characteristic, the rotating guide hub is provided, on one of its faces perpendicular to the winding axis, with a housing intended for assembling this hub with a rigid casing of a body of canvas protection.

According to one embodiment, the rigid envelope comprises a basic element, generally extended along the winding direction, and having perpendicular to this direction, a section in the shape of a "J" or cap.

The rolled up canvas and the articulated arms once folded are covered by this cap.

In another example, the rigid envelope comprises, in addition to the basic "J" element, a gutter-shaped element, interengaging means extended along the winding direction, being arranged between the basic elements and in gutter, in order to obtain a rigid envelope forming a body or trunk for protecting the canvas, with a "d" section perpendicular to the winding direction.

The rolled canvas is generally surrounded by the loop of this chest. In another example, the rigid envelope comprises, in addition to the basic element in "J", an element extended in the winding direction, for protecting the tension arms of the canvas, with a section in "w" perpendicularly to the winding direction, and means of interengagement extended in this direction between the base element in "J" and the arm protection element, so that the rigid envelope forms a cassette.

And this cassette defines a front opening for extending the arms, possibly closable by an element secured to the arms, such as a load bar, once the articulated arms are folded back.

According to one characteristic, at least one element of the body of the rigid envelope is extended in the winding direction, over a distance substantially greater than that which separates the two guide hubs in rotation, within the unitary assembly.

According to another characteristic, at least one element of the rigid envelope of the body comprises an extruded aluminum profile.

According to one characteristic, the hub comprises on one of its faces perpendicular to the winding direction, coupling means for a drive system of the winding shaft.

According to one embodiment, the hub comprises coupling means on two opposite faces in the winding direction, in order to allow indifferently the coupling of a drive system on one and / or the other of its faces.

According to one embodiment, the coupling means are arranged so that the drive system is disposed towards the outside of the unitary assembly forming the blind.

According to one embodiment, the hub includes a housing in which the coupling means are provided, in order to allow the mounting of the drive system towards the interior of the unitary assembly.

In one example, the drive system is a manual system, for example a "winch" with gear returning to the winding shaft.

In another example, the drive system is a motorized system.

According to one characteristic, the motorized system comprises an electric motor.

According to one embodiment, the rotary guide hub comprises a housing opening in the winding direction, in which is at least partially arranged a motor of the drive system, and optionally, one or more limit switches some cobweb.

A third object of the invention relates to a method of mounting a unitary element forming a blind on an anchoring device. This process provides in combination for the steps of:

- place the unitary assembly so that the canvas is rolled up;

- place at least one anchoring device in the open state;

- deposit the unitary assembly in a cradle of the anchoring device in the open state, in a direction substantially perpendicular to the winding axis of the fabric; - Place the unitary assembly in a position corresponding to a chosen inclination of the fabric;

- place the anchoring device in the closed state; and

- lock the anchoring device.

Other characteristics of the invention appear from the detailed description which follows and which is given with reference to the accompanying drawings.

The unitary assembly or awning 1 comprises a canvas or awning 2 (Figure 6-8).

The fabric 2 has two lateral edges and two longitudinal edges. The longitudinal edges are intended to be extended in the longitudinal direction X, and the lateral edges in a perpendicular direction.

Unless otherwise indicated (Figures 6 to 8), the fabric 2 is described here with its lateral edges parallel to the direction Z. But this is only an example making the description clearer, and we keep to mind that depending on the case, a different inclination can be given to the canvas 2.

One of the longitudinal edges of the fabric 2 is secured to a winding shaft 3. While its other edge is made integral to a load bar 4.

Within the unitary assembly 1, the winding shaft 3 and the load bar 4 are extended in the direction X, longitudinally.

The winding shaft 3 comprises a hollow cylindrical tube 3a, and at each of its ends in the direction X, a drive end 3b. The cylindrical tube 3a is here a rolled galvanized steel profile.

The shaft 3 has a plane of symmetry intersecting its axis of rotation, and parallel to the latter. It is therefore reversible. At the outer periphery of the shaft 3 is formed a groove 3c extended in the direction X, in the plane of symmetry of the shaft 3. The groove 3c is provided for the introduction of a longitudinal end portion of the canvas 2, as well as a connecting rod (not shown).

The part of the fabric 2 is secured in a removable manner to the winding shaft 3, under the effect of its clamping between the fastening rod and the groove 3c.

At its other longitudinal edge, the fabric 2 is made integral with the load bar 4, for example in a similar manner.

The canvas 2 is windable around, and unrollable, the shaft 3.

The unitary assembly 1 also comprises two articulated arms 5. Each arm 5 generally has the shape of a compass, deformable in an area substantially perpendicular to the direction X.

One end of each arm 5 is articulated on the unitary assembly 1, near the winding shaft 3.

At the other end, each arm 5 is secured, by an articulation, to the load bar 4.

The deployment of the arms 5 causes the load bar 4 to move away from the winding shaft 3. And consequently, the unwinding of the fabric 2. Generally, a spring housed in each arm 5 tends to deploy it, and to unwind the fabric 2.

While the winding of the fabric 2, and therefore the folding of the arms 5, is caused by rotation of the shaft 3 in an appropriate direction.

Depending on the position in which the arms 5 are adjusted when the blind is used, the fabric 2 will be deployed in a plane inclined or not relative to the horizontal (direction Z).

Two guide hubs 6 are also part of the unitary assembly 1.

On each guide hub 6, one of the drive ends 3b is pivotally mounted, so as to allow the rotation of the winding shaft 3 about its geometric axis.

The guide hubs 6 each comprise lugs 7 for attachment to a movable arm 5, respectively.

In FIG. 3, it can be seen that each hub 6 comprises two lugs 7 each provided with a hole 8 opposite the hole in the other lug 7.

This allows the engagement of a hinge pin (not shown) by pivoting one end of an arm 5, and therefore its deployment and its folding.

Here, the two tabs 7 are extended projecting from the general periphery of the guide hub 6. In the position illustrated in FIG. 3 of the hub 6, each lug 7 is extended along a plane parallel to the directions X and Z.

And each hole 3 of a hub 6 is extended in a direction parallel to the direction Y.

However, if the hub 6 is rotated around the axis X, the direction of the legs 7 and of the holes 8 is changed. As well as the general inclination of the arms 5, which are articulated on the hubs 6.

For each hub 6, the two legs 7 form a part 9 of the hub 6. The hub 6 proper and the legs 7 here form a piece of molded aluminum, in one piece. Part 9 of hub 6 has, in a plane perpendicular to direction X, an inverted "U" shape.

Each branch of the "U" of the part 9 is defined by a tab 7, and the core of the "U" 9a has a shape coincident with the profile of the hub 6, here in the cylinder sector.

On either side of the part 9 along the periphery of the hub 6, a radial clearance 9b is formed.

One of the clearances 9b allows the passage of the fabric 2.

When the winding shaft 3, the fabric 2, the deployable arms 5, the load bar 4 and the two hubs guide 6 are assembled, a unitary assembly 1 is obtained.

The assembly 1 is obviously removable.

Depending on whether the fabric 2 is unrolled or rolled up, the unitary assembly 1 is either in a deployed form or in the form of a "bundle", respectively.

In the deployed unitary assembly 1, the fabric 2 is at least partially unwound from the shaft 3, the arms 5 are unfolded, and the load bar 4 is moved away in the direction Z, from the guide hubs 6 and the winding shaft 3.

For the use of the blind, the unitary assembly 1 is deployed.

When the unitary assembly 1 forms a bundle, as in FIGS. 6 to 8, the fabric 2 is wound around the shaft 3 in almost all of it.

The load bar 4 is then brought back against the folded arms 5 near the winding formed by the fabric 2 around the shaft 3.

In the bundle state, the unitary assembly 1 has a compact shape and generally elongated in the direction X.

The different constituents of the unitary element 1 are assembled so as to avoid their involuntary displacement or uncoupling. Such a form is easy to handle. And its storage, for example in winters when the blind is not used, occupies a limited space.

In FIG. 1, the reference numeral 10 designates an anchoring device.

Here, two devices 10 allow the anchoring of a unitary assembly 1 on a support S such as a wall or ceiling, for example.

In FIGS. 6 to 8, the support S is extended along a plane parallel to the directions X and Y. It is a substantially vertical face of a wall, a beam, etc.

The support S can also have a generally horizontal orientation, such as a ceiling or a building facade apron.

Or even have any inclination relative to the vertical.

Between the support S and the device 10, a positioning wedge can be provided, for example in the form of a wedge.

The anchoring device 10 comprises holding and locking means 11, and a console 12, intended to be rigidly fixed on the support S.

The console 12 includes a bearing face 17, to be placed against the support S (possibly by means of a wedge). The face 17 is here substantially extended parallel to the directions X and Y.

Holes 18, here oblong and two in number, allow the mounting perpendicular to the face 17 of anchoring means such as screws, rigid but removable fixing of the device 10 on the support S.

The holding and locking means 11 are integral with the console 12.

They are also arranged to hold the blind 1 and the device 10 together.

As well as to allow adjustment of the inclination of the unitary assembly 1 relative to the support S.

The inclination is adjusted by rotating the unitary assembly 1 around an axis parallel to the direction X, here the geometric axis of rotation of the winding shaft 3.

This rotation brings the unitary assembly

1 in a plurality of positions, each of which corresponds to an inclination of the deployable arms 5, and therefore of the unwound fabric 2.

The holding and locking means 11 therefore allow the unwound fabric 2 to be extended substantially horizontally, or with a chosen inclination relative to the horizontal. Yet another function of the means 11 is to allow the locking of the unitary assembly 1 in the chosen position, that is to say to guarantee the maintenance of the arms 5, of the load bar 4 and of the fabric 2, with the inclination -null or not chosen.

The means 11 must guarantee that the chosen position is maintained, as long as a force of a predetermined maximum value is not applied.

These holding and locking means generally comprise:

- A receiving cradle 13 of the assembly 1;

- means 14 for indexing its inclination; - as well as a locking mechanism 15 in position, therefore with the inclination chosen.

The indexing means 14 make it possible to determine and obtain a chosen inclination of the hubs 6 and therefore of the fabric 2.

The locking mechanism 15 is distinct from the indexing means 14, and makes it possible to maintain the unitary assembly 1 with the inclination determined using the indexing means 14.

Therefore, the locking mechanism 15 is provided to take up the indexing forces, that is to say the inclination adjustment.

And it collects the significant efforts to maintain the position that the unitary assembly 1 undergoes. This recovery is called "substantially independent" because as soon as the locking mechanism 15 is arranged so as to maintain the unitary assembly 1, it frees the indexing means 14 from almost any constraint.

The means 14 are then almost no longer subjected to any effort, and inactivated.

This makes it possible on the one hand to size the indexing means 14 as closely as possible, and on the other hand to conform the mechanism 15 to obtain excellent retention in position of the assembly 1.

Another feature of the invention is that the receiving cradle 13 can be placed either in an open state (Figure 1) or in a closed state (Figures 4 to 8).

In the open state, the receiving cradle 13 provides a radial passage 16, through which it is possible to deposit the unitary assembly 1, and more precisely a part intended for this purpose of the assembly 1, in the cradle 13.

The radial passage 16 of the receiving cradle in the open state therefore allows the mounting of a unitary assembly 1 on an anchoring device 10, without it being necessary to move this assembly in the longitudinal winding direction X, and therefore without threading.

In FIG. 1, arrow A illustrates an example of removal of the assembly 1 on the devices 10.

Such removal of the unitary assembly 1 in the cradle 13 in the open state is an operation which can be carried out easily and with a reduced working mass compared to known sliding structures.

When, as in FIG. 1, two devices 10 are provided to support the unitary assembly 1, it suffices that the brackets 12 are mounted on the support S at a determined distance from each other, and that the cradles

13 are open so that assembly 1 can be placed there.

Without having to move relative to the support S, one and / or the other of the anchoring devices 10, as is necessary when it is necessary to make a threading.

As soon as the unitary assembly 1 is removed from the cradle 13 in the open state, and when the latter is placed in the closed state, the indexing means 14 are engaged with the unitary assembly 1, in order to temporarily define and maintain the tilt position which has been chosen from a plurality of possible positions.

If the position obtained during removal is not the desired one, it suffices to slightly lift and turn (around its longitudinal axis) the assembly 1, until the chosen inclination is obtained.

Then to rest the assembly 1, thereby putting the indexing means 14 into engagement, which maintains this inclination against any involuntary change.

This simple operation is carried out with reduced effort. And we have seen that the indexing efforts were taken up by the mechanism 15, once it was locked, and therefore in the closed state.

In the examples, the receiving cradle 13 has in the closed state a general internal shape of a cylinder with a substantially circular section, perpendicular to the direction X.

This cylindrical shape is defined, like a "handcuff", jointly by a movable part 20 and by a fixed part 21 of the anchoring device 10. Here, the fixed part 21 is part of the console 12. And the mobile part 20 is articulated on part 21.

In FIG. 2, the mobile part 20 is in the form of a flange and has, in a transverse plane parallel to the directions Y and Z, a general shape in an arc of a circle.

Near an end of this arc, the flange or movable part 20 has a hole 22, extended in the direction X.

The hole 22 allows the mounting of a rotation axis 23 (Figures 6 to 8), also generally extended in the direction X.

The console 12 also has holes extended in the direction X, and through which the hinge pin 23 passes.

Relative to the console 12, the flange 20 is mounted on the axis 23, rotating in a general plane of the cradle 13 perpendicular to the winding direction X. The flange 20 is thus articulated along the axis X.

The rotation of the flange 20 allows the receiving cradle 13 to pass from the closed state to the open state, and vice versa.

The amplitude of the rotation is here of the order of a quarter turn between the open state and the closed state.

In general, it is sought to choose the amplitude to bring the flange 20 horizontally to the open state, whatever its position in the closed state.

In order to limit the amplitude at the opening of this rotation, the flange 20 is provided with a projecting bevel

24.

The end bevel 24 of the flange 20 is shaped to be at a distance from a stop 25 of the console 12, in the closed state of the device 10.

While in the open state, the bevel 24 and the stop

25 are in abutment against one another, which immobilizes the flange 20 in the open state relative to the console 12.

In FIG. 6, the stop 25 is extended along a plane substantially parallel to the directions X and Z, and oriented towards the outside of the console 12.

And the bevel 24 in the closed state is oriented along a plane substantially parallel to the directions X and Y, and turned towards the bearing face 17 of the console 12. Relative to the bearing face 17 of the console 12, the flange 20 of the cradle is here articulated so as to be substantially extended at right angles, in the open state.

In Figure 1 the flange 20 in the open state is generally extended in the direction Z, that is to say horizontally.

Such a position makes it possible not only to deposit the unitary assembly 1 in the cradle 13, but also to temporarily support this assembly in equilibrium.

Thus, the unitary assembly 1 is temporarily disposed and supported by the device 10, when it rests in the cradle 13 in the open state.

In the case where the support S is horizontal, it is similarly possible to mount the mobile part - flange 20 or other - so that it is horizontal in the open state, and can also serve as temporary support for the blind 1.

At the end opposite the hole 22 of the arc defined by the flange 20, the latter comprises a flat 26, substantially parallel to the directions X and Y, in the closed state of the device 10.

In this state, a clearance 27 (FIG. 6) in the direction Z, is formed between the flat 26 of the flange 20 and the console 12.

In the examples, a concavity 29 of the flange 20, generally in the cylinder sector, delimits the movable part of the cradle 13. The concavity 29 is formed between the bevel 24 and the flat 26. In the closed state of the anchoring device 10, the concavity 29 faces the console 12 and / or the support S.

While in the open state, the concavity 29 of the receiving cradle 13 is here turned upwards, and defines with the console 12 the deposit passage 16.

Although the example illustrated provides for a receiving cradle 13, the opening of which is obtained by rotation, an alternative consists in mounting at least one movable part of the cradle in translation, for example sliding, between the open state and the closed state.

The flange 20 is part of the locking mechanism 15, since it makes it possible to obtain immobilization by clamping the unitary assembly 1. Here, the locking is obtained under the effect of a resumption of forces by friction.

This friction is also obtained during locking, at the level of contact with the fixed part 21 of the cradle 13, and more precisely of a concave surface 30 of the console 12 (FIGS. 1 and 8).

The surface 30 is generally in the cylinder sector with its convexity oriented towards the bearing face 17 of the console 12. The sectors of the surfaces 29 and 30 are substantially complementary.

Thus, in the closed state, the cradle 13 defines a cylinder centered on the axis of rotation of the shaft 3, of a part delimited by the concavity 29, and secondly delimited by the concave surface 30.

The clamping of the flange 20 in the closed position, with the flat 26 facing the console 12, is here obtained by a screw 31 of the locking mechanism 15.

On the one hand, the screw 31 is integral with the console

12.

Here, the head of the screw 31 is integral with a pivot axis 32, which is mounted on the console 12, so as to be extended in the direction X.

This mounting allows by pivoting in a Y-Z plane, either to release the cradle 13 by releasing the screw 31, or to place the latter in the locked position (Figure 7), when the cradle 13 is closed.

In this position, the screw 31 is arranged substantially in the direction Z, so as to extend in a through groove 33 of the flange 20 (Figure 2).

The groove 33 is delimited on the one hand by the flat 26. On the other hand, the groove 33 opens into a face 34 of the flange 20, opposite the flat 26 and extended parallel to the directions X and Y.

The groove 33 also opens outwards from the flange 20, that is to say opposite the concavity 29 of the cradle 13.

The groove 33 gives the end of the flange 20 opposite the bevel 24, a form of fork or double shoe. In Figure 6, at the end of the screw 31 opposite the axis 32, is mounted a nut 35. When tightening the nut 35, it is pressed against the face 34 of the flange 20, according direction Z.

The nut 35 is retracted into a flared part of the flange 20, when it is tightened.

When tightening, the flat 26 is biased towards the console 12, so as to reduce the clearance 27 provided for this purpose.

Relative to an extended plane in the longitudinal directions (X; Y or Z) of the axis 32 and of the screw 33, respectively, these two components are symmetrical and therefore reversible.

Before returning to the unitary assembly 1, other particularities of the anchoring device 10 are described.

In the examples, the console 12 which is a single piece aluminum foundry piece comprises various walls, possibly machined, with a thickness of the order of 10 mm, generally.

The console 12 comprises a base wall 36, substantially rectangular with its longest edge oriented in the direction Y.

The base wall 36 defines the bearing face 17 and is crossed by the anchoring holes 18. Two reinforcing walls 37 and 38 are respectively provided at each end of the base wall 36, in the direction Y.

The reinforcing wall 37 is extended parallel to the directions X and Z, from the bearing face 17 to near the pivot axis 32 and the concave surface 30.

The reinforcing wall 37 and the base wall 36 together define a bend in the console 12, extended in the direction X.

The other reinforcing wall 38 is parallel to the wall 37, and is extended from the bearing face 17, as close as possible to the axis of articulation 23 of the flange 20.

It is noted that the abutment 25 for supporting the bevel 24 of the flange 20 is delimited by the face of the reinforcing wall 38 opposite the cradle 13.

The console 12 also includes two yoke walls 40, substantially identical to each other, and each extended along a plane perpendicular to the direction X.

In this direction, a yoke wall 40 is provided on the one hand, and the other yoke wall 40 is provided on the other hand of the walls 36, 37 and 38. And each wall 40 is contiguous to these three walls 36 , 37 and 38.

Perpendicular to direction X, each yoke wall 40 has the shape of a crescent whose concavity corresponds to that which the walls 36, 37 and 38 jointly define. In each yoke wall 40, the concavity of the crescent defines a semicircle, intended to be generally centered on the geometric axis of rotation of the winding shaft 3.

And, with the exception of a straight external edge which is flush with the face 17 of the base wall 36, the external edges of the yoke walls 40 project in directions Y and Z, from the defined external profile by the walls

36, 37 and 38.

We see that the ends opposite to the face 17 in the direction Z (Figures 6 to 8), crescents formed by the yoke walls 40 are flat, extended in a common plane parallel to this face 17, and arranged to be substantially intersecting with the geometric axis of rotation of the winding shaft 3.

It is near these plates that the mounting holes for the axis of rotation 23 of the flange 20 and of the pivot axis 32 of the screw 31 are formed by drilling.

The axis of rotation 23 crosses the two yoke walls 40 near a free edge of the reinforcement wall 38, opposite the bearing face 17 along Z.

Furthermore, FIGS. 4 and 5 show two legs 44, 45 which form part of the console 12. These two legs 44, 45 are extended perpendicular to the direction X, projecting from the reinforcement wall 38 towards the outside of the console 12. In direction X, the tabs -4, 45 separate three housings of similar or even identical dimensions between the two reinforcing walls 40. The external profile of the lugs 44 and 45, always perpendicular to the direction X, is substantially identical to that of the yoke walls 40, projecting from the reinforcement walls 37 and 38.

Thus, in addition to the walls 40, the axis of rotation 23 also passes through holes formed in the tabs 44 and 45.

For its part, the pivot axis 32 passes through the two yoke walls 40 near a free edge of the reinforcement wall 37 opposite the bearing face 17 along Z.

Generally, the console 12 is of an external shape inscribed in a right prism with rectangular base. This base is delimited by the common plane defined by the four flat crescents formed by the two yoke walls 40.

While internally, the console 12 includes a cavity 39, partly delimited by the fixed surface, concave and in the sector of a cylinder, mentioned above.

Like the semicircular concavity of the yoke walls 40, the surface 30 is arranged to be centered on the geometric axis of the shaft 3.

The generator of this surface is therefore parallel to the direction X.

In the example illustrated, the concave surface 30 is discontinuous. Also, this surface 30 provides at least one hollow central zone 43 (FIG. 1) for access to the base wall 36.

The access area 43 is in the form of a cross when viewed in a plane parallel to the directions X and Y. It allows the positioning and tightening of the anchoring screws mounted in the holes 18

Towards the outside and in a plane perpendicular to the direction Z, the surface 30 is delimited, in direction 4 by the reinforcing walls 37 and 38 and in direction X by the screed walls 40.

The angular opening of the sector over which the surface 30 is extended is between 90 ° and 180 °, and preferably of the order of 150 °.

The cylinder sector shape of the surface 30 is defined by two pairs of foundry bosses, projecting into the cavity 39 of the console 12.

These bosses are called timing plates 41 and 42.

It can be seen in FIGS. 6 to 8 that a pair of wedging plates 41 is arranged in the part of the cavity 39 where the reinforcement wall 37 is contiguous with the base wall 36.

While the other pair of wedging plates 42 is arranged in the part of the cavity 39 where the reinforcing wall 38 is contiguous with the base wall 36. The two plates 41 or 42 of the same pair are of identical shape, and arranged in alignment with one another in the direction X.

Similarly, each plate 41 is of shape and arrangement within the console 12, symmetrical to one of the plates 42, with respect to a plane passing through the geometric axis of rotation of the winding shaft 3, and parallel to directions X and Z.

In general, each wedging plate 41 or 42 is wedge-shaped, two sides of which coincide with the reinforcement walls 37 or 38 respectively, as well as with the base wall 36.

And the third side has a profile, perpendicular to the direction X, in the form of an arc of a concave circle, which corresponds to the profile of a part of the envelope of the surface 30, delimited by a plate 41 or 42.

In the direction X, each plate 41 or 42 has a range of the order of 10 to 20 mm, and for example substantially 13.5 mm.

Each timing plate 41 or 42 of a pair is contiguous towards the outside of the console 12, at one of the yoke walls 40, perpendicular to the direction X.

With respect to a plane perpendicular to the direction X and at equal distance from the two yoke walls 40, the console 12 is generally symmetrical. Thus, a symmetrical console 12 can equally be used at one or the other of the ends of a unitary assembly forming a blind 1.

And allows, depending on the case, to articulate the flange 20 either between a yoke wall 40 and the lug 44, or between the other yoke wall 40 and the lug 45.

In the direction X, the dimension of the articulation part (hole 22) of the flange 20 is less than the corresponding dimension of the console 12, that is to say less than the space provided between the walls 40 and the legs 44, 45, to receive this part with play.

In this case, this space of the console 12 has a dimension in the direction X of the order of 20 mm. As for the corresponding dimension of the flange 20, except in its articulation part, it is of the order of 40 mm.

To allow it to change its mounting position in direction X, the flange 20 also has a plane of symmetry, perpendicular to direction X.

Once positioned on the console 12, on one "side" or the other, the flange 20 is held in position in the direction X, but is able to be pivoted about the axis 23.

To change the position of the flange 20, it is then necessary to disassemble the pin 23 to extract it from the flange 20 and the console 12, then place the flange 20 at the location of its choice, before reassembling the axis 23. With this arrangement, the flange 20 is received as desired on one side or the other of the plane of symmetry of the console 12.

More specifically opposite one or the other of the two pairs of wedging plates 41, 42 which are provided on either side of the plane of symmetry.

The console 12 is therefore designed to include two locations for receiving the flange 20, each of which allows collaboration with a longitudinal end of the assembly 1.

In each receiving position, the flange 20 is closer to the free end of the assembly 1 than the legs 7 of articulation of the corresponding arms 5.

These tabs are then located opposite the unoccupied receiving location, intended for mounting at the other free end of the assembly 1.

Back to the indexing means 14 of the anchoring device 10. Here they are provided on the movable flange 20, which partly defines the receiving cradle 13 and of which is part of the locking mechanism 15.

This although the locking mechanism 15 on the one hand, and on the other hand to the indexing means 14 are distinct, in the sense that the forces applied to the first when using the blind, are only transmitted to the second in a negligible part.

In the examples, the locking mechanism 15 takes up most of the immobilization efforts of the unitary assembly 1 by friction, and therefore by connection without obstacle.

As for the indexing means 14, in the example illustrated, they establish an obstacle connection between the unitary assembly 1 and the anchoring device 10.

Although other protruding and / or concave shapes may be provided, the indexing means 14 of the device 10 are here in the form of toothing 46.

Each tooth of the teeth 46 is extended in the direction X, on the flange 20. These are straight teeth, arranged projecting from the cylinder sector concavity 29 of the flange 20, towards the inside of the cradle of reception 13.

In direction X, the dimension of the teeth

46 is of the order of 15 mm, so that a smooth area is formed between the transverse sides of the flange 20 and the longitudinal ends of the teeth, symmetrically, on each of its sides.

The toothing 46 generally comprises less than ten teeth, and here five teeth arranged substantially midway between the flat 26 and a peripheral end.

47 of concavity 29, opposite to flat 26.

Therefore, when the unitary assembly forming blind 1 is mounted on an anchoring device 10, the teeth 46 are arranged substantially in line with the geometric axis of rotation of the winding shaft 3, in the direction

Y. The teeth 46 are arranged along the longitudinal dimension so that, whatever the position of the flange 20 relative to the console 12, these teeth are located in a common plane with a plate 41 and the corresponding plate 42, close to either of the yoke walls 40.

In other words, the flange 20 is arranged so that in one or the other of its positions in the direction X, the teeth 46 and the useful part of the surface 30 are arranged facing one another on the same diameter of the cradle. 13.

In FIG. 2, a graduation 52 is provided on the flange 20.

The graduation 52 here delimits angular deviations of 5 ° on a sector of the concavity 29. This sector defines an opening of 120 °, symmetrical with respect to a straight line of direction Z and sequent to the center of curvature of the concavity 29.

The graduation 52 is arranged so as to determine, when the flange 20 is in the open state, the inclination given to the unitary assembly 1, once the cradle 13 in the closed state.

This determination is obtained by matching an angular difference of the graduation 52 with an indexing mark 53 of the unitary assembly 1.

In the example, the graduation 52 is arranged so that by placing the mark 53 opposite the marked difference of 0 ° when the flange 20 is open, the inclination of the fabric 2 unwound after closing the flange 20, ie 0 °.

A precise inclination adjustment can thus be carried out with the invention, before the assembly 1 is locked in position and without unwinding the fabric 2.

In addition, it is easy with the invention to ensure that the two ends of the blind 1 in the direction X, are adjusted identically so that the two arms 5 are deployed symmetrically.

The guide means 6 of the embodiment of Figures 3 to 5 is now described.

This hub 6 comprises, in addition to the tabs 7, an external bearing 48, designed to be deposited in the receiving cradle 13 and immobilized by the locking mechanism 15.

And an indexing form 49 (FIG. 1) of the hub 6, intended to be engaged in a complementary manner with the means 14.

In general, the hub 6 has a cylindrical external shape with a circular cross section, complementary to the interior of the receiving cradle 13.

We have seen that here the hub 6 was a single piece of aluminum casting.

Within this room, there are mainly two parts 50 and 51. Part 50 has a wall perpendicular to direction X, and in this direction, with a thickness of the order of 10 mm.

Adjoining the part 50, the part 51 comprises a generally cylindrical jacket, extended in the direction X and of diameter complementary to the radius of curvature of the surface 30.

The two radial clearances 9b are formed in this jacket of the part 51. And between these clearances 9b, the tabs 7 mentioned above project from the core 9a of the outside diameter of the cylindrical jacket.

It is this shirt of part 51 which defines the scope 48.

In the direction X, the sleeve of the part 51 has a dimension making it possible to have, with limited play, the hub 6 between the yoke walls 40, and therefore partially inside the cavity 39 of the console

12.

In this position, the jacket of the part 51 rests against the two pairs of plates 41 and 42 of the surface 30.

And as we saw above, the flange 20 presses against one mainly of these pairs of plates 41, 42, the corresponding surface of the hub 6.

This provides a large area of force recovery by the closed cradle 13, and makes it possible to obtain excellent locking in position of the blind 1. Thanks to the invention, the locking is capable of maintaining a chosen inclination under load applied to the arms 5, with a dimension or projection of the latter measured from the shaft. winding 3 to the load bar 4, of the order of 3 m.

In the example of FIG. 3, the complementary shape 49 is formed in the part 50. It comprises a hollow toothing in a semicircle, the teeth of which have their apex extended substantially flush with the external surface 48, without projecting from it.

Each tooth of this complementary shape 49 is shaped so that the neighboring teeth 46 of the indexing means 14 can enter it.

They are therefore straight teeth, the respective concave and projecting profiles of which allow mutual engagement of the hub 6 and the flange 20.

Because the complementary shape 49 is extended over a much larger sector - slightly less than the half-periphery of the second part 51 - than the indexing means 14, their mutual engagement can be obtained in a plurality of positions.

Each of these positions corresponds to a possible inclination of the awning fabric 2 when it is unrolled.

In the examples, the pitch or angular distance between two teeth of the indexing means 14 and of the shape complementary 49 corresponds to 5 ° of inclination of the unrolled fabric 2.

With the arrangement comprising the flange 20 of FIG. 2 and the guide hub 6 of FIG. 3, it is possible to obtain a maximum angular adjustment of plus or minus 60 ° relative to a central position where the reference

53 is opposite the gap marked 0 °.

The reference 53 is centered relative to the semi-circular toothing 49, and at equal distance from the two legs 7 in the direction Y. Here, it represents an arrow.

It is noted that in the position illustrated in FIG. 3, the hub 6 has a plane of symmetry perpendicular to the direction Y and intersecting with the geometric axis of rotation of the winding shaft 3.

In fact, the same hub 6 can be used at one or the other of the ends of the unitary assembly 1. It is therefore reversible.

In direction X, the hub 6 is externally delimited by two parallel transverse faces 54 and 55 (Figure 4). The face 54 also delimits the part 50.

The transverse faces 54 and 55 are respectively intended to be partly opposite a yoke wall 40 of the device 10. Thus, when it is housed in the cavity 39 of this device, the hub 6 is positioned longitudinally by the walls 40, which therefore form stops in the direction X. In the examples, the transverse face 54 is said to be external, because relative to the rest of the assembly 1, it is arranged at the end.

And the face 55 is said to be interior.

A housing 56 extended in the direction X inside the hub 6, opens to the inner face 55.

The housing 56 is substantially cylindrical with a transverse round section. And its diameter is greater than that of the shaft 3 which projects there through a longitudinal end.

The clearances 9b open on the one hand into the housing 56, on the other hand at the periphery of the bearing surface 48, and are generally extended in the direction Z (FIG. 3).

Opposite the internal face 55, the housing 56 is delimited longitudinally by a transverse wall 57 of the part 50 (FIG. 4).

In the wall 57 is provided a bearing 58, extended coaxially with the axis of rotation of the winding shaft 3. A cylindrical stud 59 is pivotally mounted in the bearing 58.

On the one hand of the wall 57, one end of the stud 59 is linked in rotation to a drive end piece 3b of the winding shaft 3. Here, the stud 59 and the end piece 3b form only one room. On the other hand, the stud 59 is connected to a drive system 60, which makes it possible to rotate the shaft 3, and therefore to wind the fabric 2.

In FIG. 4, the drive system 60 which includes an angle transmission and reduction gear 61, is of the manual type. It is provided with a ring 62 extended transversely, taken with a crank.

The manual system 60 is mounted on the hub 6 by means of coupling means 63.

The coupling means 63, here threaded bores distributed around the periphery of the bearing 58 (FIG. 3), lead to the external face 54 as well as to the transverse face of the housing 56.

The holes of the means 63 being angularly arranged at regular intervals, the system 60 can be mounted on the hub 6 in as many angular positions as there are holes, in particular according to the inclination chosen for the blind.

The fact that the hub 6 comprises coupling means 63 on two opposite faces in the direction X, indifferently allows the coupling of a drive system 60 on one and / or the other of its faces.

The means 63 allow the mounting of a system 60 outside the hub 6, as in FIG. 4. Or inside the housing 56, as in FIG. 5. The system 60 of this figure comprises a motor 67, fixed to the wall 57 and connected to the shaft 3. This motor 67 which is disposed in the housing 56, is electric.

A wire 64 connects it to a power source and / or control 65.

Also in the housing 56, at least one sensor 66 is provided, capable of triggering / interrupting (in the case of a limit switch sensor) the rotation of the shaft 3 under the effect of the motorized system 60. Here, the sensors 66 are integrated into the motor 67.

These sensors 66 also make it possible to determine, as a function of the number of detected turns of the shaft 3, the degree of winding of the fabric 2.

It is noted that the coupling means 63 are here identical for a manual or motorized system 60, inside or outside. So that the replacement of one system 60 by another, of different structure, can be carried out without modification or machining of the hub 6.

As with such a change, the hindrance of the devices 10 remains identical.

Furthermore, the housing 56 is arranged to participate in the assembly of the hub 6 with a rigid body 68 for protecting the wound fabric 2.

However, as in FIG. 1, the assembly 1 can in a so-called "standard" version, be devoid of protective body for the fabric 2. In the examples, the unitary assembly or blind 1 is provided at each of its ends in the winding direction X, with a hub 6 for guiding in rotation.

According to the three embodiments of the figures

6 to 8, the body 68 is generally extended in the winding direction X, over a distance substantially greater than that which separates the two internal faces 55 of the guide hubs 6, within the unitary assembly 1.

In fact, the body 68 projects into the housings 56. Each free end of the body 68 abuts in the direction X, against a shoulder 70. This stiffens the assembly of the body 68 and the hub 6.

Screws 71, for example two to four in number, complete the fixing of the body 68 to a hub 6. They are mounted longitudinally in holes in the wall 57, and forcibly engaged in longitudinal cells 72 of the body, so to form a tapping.

In FIG. 6, the body 68 comprises only a base element 69.

The basic element 69 is generally extended along the winding direction X, and has, perpendicular to this direction, a section in the shape of a "J" or cap.

It therefore constitutes a partial rigid envelope, the part of which corresponding to the shaft of the "J" protrudes from the housing 56 by one of the clearances 9b, called "superior". While the cylindrical part of the base element 69 is at the periphery of the fabric 2.

The projecting part of the element 69 is extended, with the same inclination as the fabric 2 relative to the horizontal, above the arms 5 and the bar 4 when the assembly 1 is in bundles.

In the example of FIG. 3, the rigid envelope comprises, in addition to the basic element 69 or cap, a gutter-shaped element 73.

The gutter element 73 is provided so that its longitudinal ends are each housed in a housing 56. These ends therefore have a shape complementary to that of the interior of the hubs 6.

Interengaging or joining means 74, extended in the direction X, are arranged between the base elements 69 and in gutter 73, in order to rigidly assemble them.

These means 74 comprise a concave rib extended along the longitudinal edge of an element of the body 68.

And a male rib on the edge of the other element. The concave and male ribs are engaged one inside the other which secures the two elements to be assembled.

In FIGS. 6 to 8, the element 69 is provided with a concave female rib of the means 74, provided at the longitudinal edge of the free end of the curvature of the "J". In FIG. 7, the gutter element 73 has a male rib of shape complementary to the female rib of the element 69, so as to be engaged therein. This assembly of elements 69 and 73 gives a body 68 with a "d" section lying, perpendicular to the direction X.

The male rib of the means 74 is offset radially towards the inside of the body 68, so that the latter has a smooth appearance on the outside.

This body 68 forms a box, the part of which corresponds to the loop of the "d" surrounding the winding of the fabric 2.

This part of the element 73 is extended between the shaft 3 and the folded articulated arms 5, to protect the fabric winding 2 from the outside.

In the example of FIG. 8, the rigid envelope of the body 68 comprises, in addition to the element 69 in "cap" and instead of the gutter 73, an element 75.

The element 75 is generally extended in the winding direction X and allows the protection of the fabric 2 as well as the folded arms 5.

It has a cross section in "w", and means of interengagement 74 similar to those of element 73.

Like the element 73, the ends of the element 75 are housed in the housings 56 of the hubs 6. Here, the body 68 forms a cassette, the transverse protruding parts of the devices 10 comprising cheeks 77.

Each end of the element 75 projects from a hub 6 towards the front and in a direction perpendicular to the direction X, through the clearance

9b lower, the upper clearance 9b being traversed by the base element in cap 69.

And this cassette defines a front opening 76 for extending the arms 5. The opening 76 here can be closed by the load bar 4.

For this purpose, the bar 4 has a raised cross section, extended between the element 69 and the element 75.

Brushes 78 mounted on elements 69 and 75 form two longitudinal barriers for closing and cleaning.

In FIGS. 6 and 7, the bar 4 is provided with a lambrequin 79.

With the elements described, the assembly 1 is modular, since certain components of the body 68 can be added or interchanged, depending on the destination and the use of the blind 1.

The illustrated shapes of the body 68 have the advantage of avoiding any friction with the fabric 2, which limits wear. And at least one element of the body 68 comprises an extruded aluminum profile, which makes it possible to obtain, at a competitive cost, a light and rigid assembly 1.

Indeed, to obtain such a body element, it suffices to cut a section of appropriate section, to a chosen length.

The invention relates to a method of mounting a unitary element 1 forming a blind on an anchoring device 10.

This process involves the combination of steps of:

- Place the unitary assembly 1 so that the fabric 2 is wound;

- placing at least one anchoring device 10 in the open state;

- Deposit (A) the unitary assembly 1 in at least one cradle 13 of the anchoring device 10 in the open state, in a direction substantially perpendicular to the winding axis X of the fabric 2;

- Place the unitary assembly 1 in a position corresponding to a chosen inclination of the fabric 2; - Place the anchoring device 10 in the closed state; and

- lock the anchoring device 10.

Conversely, for example in winter, the bundle 1 can easily be removed from the support, by opening the device (s) 10, and radially removing the blind from the cradle 13, for storage.

Other steps are described above. The invention, which also relates to a support S equipped with an anchoring device 10 and / or an installation as mentioned above, is not limited to the illustrated embodiments.

In the case where the unitary assembly comprises a rigid body for protecting the wound fabric, the external bearing surface 49 of the unitary assembly 1 can at least in part be arranged on the body 68, at a distance from the hubs 6.

The same can be true for the complementary shape 49, which is then at least partly on the protective body 68.
