Description

GUIDING DEVICE WITH PIVOTING JOINT FOR A SHUTTER

The invention relates to a guiding device for rolling shutters or the like, intended to guide an apron formed of apron blades connected together in an articulated manner in the direction of deployment of the apron, comprising two guiding rails extending parallel to one another on each other. the length of which extends a guide groove for the apron blades, the guide rails having a first guide branch which can be rigidly connected to the frame of a window, and a second guide branch which can be placed in projection and attached to the first guide leg by means of a pivot joint.

In the context of the invention, the term "shutters and the like", outside the shutters, also include other devices used for shading, such as rolling doors, textile sun visors having a rollable fabric (instead of an apron made of interconnected blades), etc., which can be mounted on all kinds of building openings, such as facade or roof windows, doors , passages, as well as on roofs and glazed facades (greenhouses).

Guiding devices of this type are frequently used for roller shutters of roof windows to ensure that the window leaf can pivot about its pivot axis when the roller shutter box is mounted above the window roof. A roof window rolling shutter comprising guiding devices of this kind is known, for example, from DE 37 36 153. Al. Similar devices are described in DE 28 42 381 A1, as well as in document FR 2 588 036 A1. However, roller shutters comprising segments of guide devices, or guide branches, are also used on front windows. , pivoting, of the kind in question, as described, for example, DE 29 709 443 U l.

Faced with this fact, the invention aims to improve a guiding device of the kind in question so that it is resistant to bad weather and has a pleasant visual appearance. This problem is solved by the guide device as defined in preamble and characterized in that the pivot articulation is disposed between the plane defined by the frame of the window, on the one hand, and the plane defined by the second guide branch, on the other hand. In the context of the invention, the term "plane of the window frame" denotes a plane in which is contained the surface of the window frame which is directed towards the outside and by "plane of the guide branches". planes in each of which is contained the outer surface of the corresponding guide branch 15 which is remote from the frame of the window.

This advantageously avoids that the pivot joint protrudes above the outer surfaces of the guide branch or that it is mounted externally to the outer surfaces of the guide branch. In this way, on the one hand, the joint is better protected from the influences of bad weather, while on the other hand, one obtains a visible aesthetic surface and, as a result, a pleasant overall appearance for the window. equipped with shutters and for the entire facade, especially when the hinge is fully placed between the window frame and the outer surfaces of the guide branches which are remote from the window.

In this construction, the pivot joint is advantageously arranged, preferably integrated, in the guiding device in such a way that, at least in a coaxial, non-projection extended position of the guide branch, it is covered by the latter. In this way, the pivot joint is not visible from the outside, so that the guide device according to the invention meets the severe aesthetic requirements of modern architecture.

This result can be achieved, for example, by the fact that, in the extended position, the guide legs delimit a housing space on several sides and that the pivot joint is disposed in the accommodation space. The guide branches can then be formed by hollow profiles, in particular identical, each having a chamber, the chambers together forming the housing space. Since guiding devices are frequently constituted by profiles having a guide groove for the rolling shutter apron, it is possible to obtain an economical manufacturing without much modification of the manufacturing facilities.

The pivot joint may comprise two half-joints, in which case, on a half-joint, is formed a hinge housing which cooperates with a hinge projection belonging to an adjacent half-joint.

The pivot joint for the roller shutter guiding device of the invention is exclusively composed of at least one pair of half-joints having constitutions complementary to one another. This allows simple mounting of the guide rails. When the half-joints are furthermore advantageously constructed so that they can be connected to one another or separated from one another by a folding movement or, respectively, unfolding, the guide branches equipped with half-joints can be mounted and dismantled simply by folding and unfolding, and therefore without the pivot joint being accessible from the outside. One can thus dispense with an additional immobilization by rivets or equivalents, mounted on the side. When the half-joints made in the form of inserts are further adapted to the section of a chamber provided in the corresponding guide branch of the guide device, they can be accommodated in the housing space formed by the chambers.

To obtain the aesthetic appearance and the protection against the weather, the half-joints are preferably covered by the guide branches, at least in the extended position, but advantageously also in the projection position, by the guide branches. This can advantageously be obtained by the fact that the pivot axis of the pivoting articulation is disposed in the region of the outer edges of the guide branches which are directed toward each other and away from the frame of the window. In this way, it is possible to avoid a miter cut of a guide leg, such as would be necessary if the pivot axis was in a middle region, located between the plane of the window frame and the outer edges guide branches, as well as the opening that would then be formed in the extended position. The hinge housing and the hinge projection can be rotatably engaged with each other by means of circle-shaped contact surfaces which extend coaxially about the pivot axis, the contact surfaces extending at most over an angular sector of 180 °. In this way, all of the space required for the hinge housing and for the hinge projection may be provided between the pivot axis extending on the outer edge of the guide leg and the frame of the hinge. window. In total, the mounting of the guiding device is considerably simplified, as is explained in more detail in the following. In the context of the invention, half-articulations or complementary articulating parts, in particular half-articulations which complement one another to form a pivot joint (projection articulation).

The hinge housing preferably has two branches extending in parallel and forming, with a floor segment, a substantially U-shaped housing for the hinge projection of a neighboring hinge portion. It is also rotted to consider a configuration of double U-shaped for two projections hinge. In this case, it can be provided on the inner surfaces of the branches of the hinge housing which are directed towards each other, guiding projections extending arc-shaped or circular sectors coaxially to the pivot axis and cooperating with mutually opposite guide grooves provided on the outer surfaces of the hinge projection. However, one could also imagine to provide the guide projections on the hinge projection and the guide grooves on the hinge housing.

In a preferred embodiment, the front surfaces of the hinge housing terminate, via a radius of rounding, in a lower outer surface of the hinge half, so that they can behave like surfaces. additional guide means when the corresponding opposite surfaces of the adjacent hinge projection extend in a complementary manner with a corresponding rounding radius. This provides a particularly compact construction for the pivot joint at the same time as a great strength and a long life.

In an exemplary embodiment of the invention which is advantageous for the manufacturing technique, the half-joints are constituted by inserts that can be partially inserted into the guide branch.

Furthermore, it has proved advantageous for the manufacturing technique that the half-joints comprise bores in which fastening means can be passed, for example screws, studs or rivets, which pass through at least part of the guide branches, to ensure their axial immobilization, for example by the front side or the rear side of the guide branch considered. In this solution, one advantage is that the guiding devices need only be drilled for screwing in the region of the hinge, so that no further machining is necessary. The guiding device can thus be manufactured in a simple and economical way.

In one form of construction of the invention, it is provided that the guide legs each comprise a housing for a hinge insertion and at least one neighboring guide groove (guide channel) for the roller shutter. In this way, a particularly compact construction of the guiding device is obtained, which makes it possible to obtain, also in the folded state of the guide branches, a reliable guide for the shutter. In this case, it has proved advantageous for the manufacturing technique that the half-joints are castings and / or milled parts.

However, alternatively, one could also imagine making the half-joints in one piece with the guide branches. This solution has the advantage of not requiring fasteners for the construction of the hinge parts.

It has been found particularly advantageous that the guide branches can be releasably connected to one another. The mounting of the guide rail is preferably effected by means of a folding movement or projection of the guide branches. In other words, the coupling or uncoupling of the guide branches, for the formation of the guide device is effected respectively by a hooking or unhitching of the hinge portions of the guide branches. In a preferred embodiment, in the folding movement, the half-joints form, at least partially, a bond for safety of shape, so that a pivot joint is obtained substantially without play and a high strength.

The guiding devices can be made of metal, in the form of drawn or press-spun parts, having a high surface and shape accuracy, or they can be extruded from plastic.

In a method used to connect guiding rails of a guiding device, the hinge portions of the guide branches which are of complementary shape with respect to each other are inclined so as to preferably form an angle acute. Then, the half-joints can be folded into one another to assemble the hinge branches. In particular, the lower guide legs of the guide devices can be simply nested and separated, respectively for assembly and disassembly, by pivoting 180 °. The coupling and uncoupling of the lower guide legs of the guide device is preferably carried out without tools. The pivoting of the guide device according to the invention has proved particularly convenient for mounting.

In the context of the invention, a guide branch of a guide device can be rigidly connected to the frame of a window and the other branch can be put in projection. However, the invention is not limited to this case.

Other advantageous developments of the invention are the subject of other secondary claims.

Figure 12 is a representation of the lower upper guide legs before folding. The invention is explained hereinafter with reference to a guiding device, generally designated 1, for a roller shutter associated with a window 2. However, the invention is in no way limited to roller shutters for windows but it can be used for shadow devices of all kinds, in which an apron, canvas or the like is to be guided in projection guide rails. FIG. 1 is a diagrammatic representation of the window 2 on the outside of which the guide device 1 is arranged for a rolling shutter apron (not shown). In an upper region of the window, is arranged a shutter housing not shown (roller shutter box), in which is mounted a winding shaft provided for the strip of shutters (rolling shutter apron) which can be rolled up and which is formed of rolling shutter blades. The guiding device 1 comprises two guiding rails 4, 6 extending parallel to each other, provided for the lateral guiding of the shutter strip which is wholly or partially unrolled, and which are connected to the right of an end segment. In the exemplary embodiment of the guiding device 1 which is shown, the guide rails 4, 6 are divided in the transverse direction, each time about a quarter of their length from the upper edge of a window frame 10, and they are pivotally joined by a pivot joint 12. An upper guide branch 14 of the two guide rails 4, 6 is attached to the window frame 10 while a lower guide branch 16 of the guide rails 4, 6 is pivotable with respect to the first, relative to the window frame 10, about a pivot axis 18 shown schematically, so that it is possible to adjust a pivot angle α of the lower guide branch 16 with respect to the window frame 10. The pivot axis 18 extends parallel to the plane or surface of the shutter strip or of the window 2. The guide rails 4, 6 are preferably constituted by stretched or press-spun, aluminum or plastic parts, which have a high surface and shape precision. Since the guide legs 14,16 of the left and right guide rails are likewise configured and symmetrical to one another, the description of the guide branches is valid for the two guide rails in each case.

As can be seen in particular in Figure 2, which shows the guide rail 4 in the region of the pivot joint, the inner guide branch 16 not being shown, the guide branches are connected one to the other pivotally through hinge portions 20, 22 of complementary conformations, which complement each other to form the pivot joint 12. According to Figure 2, is formed on the upper hinge portion 20 a hinge housing 42, 44, formed of two parallel branches 42, 44, which cooperates with a hinge projection 80 formed on the adjacent hinge portion 22 (the rear branch 44 is hidden in Figure 2) .

As can be seen in particular in FIG. 3, the pivoting branches 14, 16 each comprise a front bearing surface 28 and a contact surface 30 which are flatly supported against each other in the extended position, not shown, i.e. in the case of a pivot angle α of about zero degrees, so that the upper outer surfaces 31 of the guide legs form a smooth visible surface which satisfies high 15 aesthetic requirements. In an extended position, not shown, of the guide rail 4, the pivot joint is completely concealed by the guide branches 14, 16. The pivoting movement of the guide branches 14, 16 is limited towards the extended position by the arrival of the contact surface 30 on the bearing surface 28. As is explained with reference to FIG. 4, by way of example for the two guide branches 14, 16, the guide branches 14 16 which consist of hollow sections comprise a roughly C-shaped guiding groove 32 which forms a guideway intended to guide and receive the marginal region of the shutter (not shown), so that the window 2 (see Figure 1) can be closed without allowing light through the shutter. The guide branches 14, 16 each further comprise a substantially rectangular chamber or housing 34 disposed adjacent to the guide groove 32, and is intended to receive the hinge portion 22 constituted by a hinge insertion in this example embodiment of the invention. The chamber 34 and the guide groove 32 are spaced from one another by an inner wall 36 of the guide branches 14, 16. To reduce the weight while maintaining a high rigidity, the guide legs 14, 16 are provided. stiffening ribs 38 extending in the axial direction.

As can be seen in particular in Figure 5, the half-joints 20, 22 are constituted by inserts which are inserted in part in the guide legs 14, 16. To fix axially the half-joints 20, 22 in the guide branches 14, 16 may be provided with holes 45 by means of which the half-joints 20, 22 can be anchored with the guide branches 14, 16 by means of pins not shown which pass through the outer walls of the guide branches 14, 16. In the embodiment shown, there are provided in the hinge parts 20, 22 through holes 40 spaced from each other in the longitudinal direction of the guide legs 14, 16. A benefit of this solution is that the guide rails 4, 6 have to be drilled only in the region of the hinge 12 to allow screwing, so that no further machining is necessary. The guiding device 1 can thus be manufactured in a simple and economical manner.

FIGS. 6 and 7 show a representation corresponding to FIGS. 4 and 5 of half-joints 20 inserted in the upper guide branch 14. A detailed description of the half-joints 20, 22 is given below with reference to FIGS. to 11, which are isolated representations of the half-joints 20, 22.

Figures 8 and 9 respectively show an isolated representation of the half-joint 20 provided with a hinge housing respectively 42, 44 without and with a representation of the hidden edges. Since the half-joints 20, 22 of the left and right guide rails 4, 6 are of the same construction, the description of the articulation parts 20, 22 will be worth each time for the two guide rails 4, 6 .

According to Figures 8 and 9, the hinge housing 42, 44 of the half-joint 20 comprises two branches 42, 44 extending parallel and which form a housing opening 46 approximately U-shaped for the projection 80 (see Figure 2) of the hinge portion 22 adjacent. On inner surfaces 48, 50 of the branches 42, 44 which are directed towards each other, are formed respectively guide projections 52, 54 each extending in the form of an arc and arranged in a semicircle, which have a roughly rectangular section and which cooperate with mutually opposite guide grooves 56, 58 of the articulation projection 80 of the other half-joint 22 (see Figure 2). The guide projections 52, 54 partially delimit a substantially cylindrical recess 60 which opens towards an upper bearing surface 62 and towards the housing opening 46. The front surfaces 64, 66 of the branches 42, 44 of the hinge housing 42, 44 which are directed towards the adjacent hinge portion 22 each end approximately in the form of a quarter circle, through a radius of radius r in a perpendicularly lower outer surface 60, which belongs to the half-joint 20. Here, the end surfaces 64, 66 form arcuate guide surfaces 20 which cooperate, according to FIG. 2, with surfaces 70, 72, of corresponding shape, a hinge projection 80 of the neighboring half-joint 22. The hinge branches 42, 44 end without modification of the outer diameter, with a rectangular cross-sectional shape, in an extension 26 half-arti 20. The half-joint 20 can thus be fitted as far as desired in the chamber 34 (Figure 2) of the guide branch, the holes 40 can serve as benchmarks for mounting. When the surfaces 64, 66 (of the radius of radius r) remain visible, it is also possible to provide a precise or tightening adjustment, so that pins may be omitted for immobilization.

Figures 10 and 11 are each an isolated representation of the half-joint 22 with the hinge projection 80 complementary to the hinge housing 42, 44 missing or respectively provided with hidden edges. Here, the guide grooves 56, 58 extend in positions distant from each other, respectively in the lateral surfaces 74, 76 of the hinge projection 80 in the form of an arc of a circle, coaxially around the pivot axis 18 (Figure 1) and extend over a circle sector in the form of a semicircle. The guide grooves 56, 58 which are arranged opposite each other in the hinge projection 80 have a roughly rectangular shape and they partially delimit the hinge projection 80 of approximately half form. -cylindrical which can be engaged in the complementary recess 60 existing between the branches 42, 44 of the hinge housing 42, 44 (see Figures 8 and 9) so as to rotate, the hinge projection 80 ending here in an extension 24 with the interposition of shoulder surfaces 70, 72 ,. The front surface 82 of the hinge projection 22 terminates, with the interposition of a round radius R, in a lower outer surface 84 which extends perpendicularly to the front surface. As can be seen in particular in FIG. 2, for the formation of the guide rails 4, 6, the guiding projections 52, 54 dive, with a safety fit, into the respective guide grooves 56, 58 of an adjacent guide leg 14, 16 while in the mounted state of the guide rail 4, 6, the guide branches 14, 16 can move relative to one another between a rotated position maximum and an extended position.

The mounting of the guide device 1 is explained below with reference to FIG. 12, which shows an upper guide branch 14 and a lower guide branch 16 before folding.

The mounting or dismounting of the guide rail 4, 6 is effected by a folding or unfolding movement of the guide branches 14, 16. This means that the coupling or uncoupling takes place by a hooking or a stall respectively. half-joints 20, 22, the half-joints 20, 22 entering a connection for safety during folding. According to FIG. 12, during the assembly of the guiding device 1, the guide branches 14, 16 are inclined with the half-joints 20, 22 of complementary configurations, such that they enclose an acute angle R of about 5 to 30 °. Then, we can fit the half-joints 20, 22 one in the other to assemble the guide branches 14, 16. According to Figure 12, the folding angle is about 170 °. The folding direction corresponds to the direction of the arrow. The disassembly of the guiding device 1 is effected correspondingly in the reverse order of succession by an unfolding movement.

The guiding device according to the invention is not limited to the embodiment described which comprises guide legs 14, 16 can be separated without tools but, on the contrary, it is also possible to position the half-hinge 20 22 within the guide legs 14, 16 so that these guide branches 14, 16 can not be separated without disassembly of the hinge parts.
