Description

Field of the invention

[0001] The present invention relates generally to the technical field of systems for anchoring a roller blind to a supporting structure such as a door or a window, and in particular to an anchoring profile usable with such a system. State of the art

[0002] Roller blinds are well known for their use on load-bearing structures such as walls or door or window frames. These blinds generally include a connecting profile attached to vertical and horizontal edges. Such connecting profiles are designed, for example, in the form of zippers or molded polymer profiles.

[0003] On the other hand, anchoring systems comprise elongated support profiles which are fixed to the wall or frame, for example by means of screws, which are generally U-shaped, and anchoring profiles, generally also referred to as rails, which are integrally arranged in the fixed support profile.

[0004] The roller shutter end connecting profile is therefore slidably connected to the rail to allow the shutter to slide, for example, in the case of roller shutters, to open and / or close them, while ensuring that the shutter remains attached to the support profile, i.e., to prevent pulling the shutter from disengaging the connecting profile from the rail. The rail therefore includes an elongated seat within which the roller shutter end connecting profile is slidable.

[0005] The common anchoring profiles (rails) have a complementary seat at the end of the roller blind. Therefore, each roller blind anchoring system requires a specific connecting profile and a specific anchoring profile or rail. This aspect is further emphasized by the fact that no standard exists and the market offers a large number of different connecting profiles.

[0006] Such a disadvantage is particularly regrettable given that the companies that provide curtains with connecting profiles for the roller blinds are different from the companies that manufacture the rails and support profiles, which are usually extruded aluminum profiles.

[0007] This represents a necessary limitation of the anchoring and generates increased costs both for profile manufacturers, who must be provided with specific instructions for the geometry of the profiles, and for system installers, who must ensure that the parts are all complementary to each other.

[0008] Small dimensional errors therefore cause the connecting profile to become loose, so that the anchoring of the roller blind and / or the ability to move the roller blind is not guaranteed. Summary of the invention

[0009] The invention is based on the object of at least partially overcoming the aforementioned disadvantages by providing an anchoring profile which has a high functionality and is cost-effective.

[0010] It is a further object of the invention to provide a versatile anchoring profile.

[0011] A further object of the invention is to provide an anchoring profile which has increased sliding properties.

[0012] Another object of the invention is to provide an anchoring profile that is particularly resistant.

[0013] These and other objects of the invention which will become apparent hereinafter are achieved by an anchoring profile according to claim 1 and a system according to claim 9 comprising such an anchoring profile.

Detailed description of some preferred embodiments

[0016] With reference to the figures referred to above, a protection system 1 which can be installed in an opening such as a window or a door is described below.

[0017] System 1 essentially comprises a roller blind. The system can be a sun protection system and / or a privacy protection system, depending on the configuration of roller blind 2.

[0018] The system may therefore comprise a window roller 5 for rolling up the blind 2 in a manner known per se, as shown schematically in Fig. 12 shown.

[0019] The system may further comprise a support profile 200 configured to be attached to the door or window. Preferably, the support profile 200 may be attached to a door or window in the sliding direction of the roller blind, for example, vertically.

[0020] It is clear that the system may comprise a pair of support profiles 200 to define a pair of posts.

[0021] Advantageously, at least one anchoring profile 10 can be provided. Such an anchoring profile will also be referred to below as a guide rail or rail. The anchoring profile 10 can be attached to the support profile 200. The latter can, for example, be substantially U-shaped to form a seat inside it for receiving the anchoring profile 10. The anchoring profile 10 can be connected to the support profile 200 in a manner known per se, for example by means of springs, male or female elements, or other systems.

[0022] Suitably, the anchoring profile 10 can be inserted into the support profile 200 and fastened thereto using suitable means 210, which can comprise, for example, stop surfaces and / or springs and / or other fastening systems in a known manner.

[0023] Fig. For example, Figure 10 shows the anchoring profiles 10 arranged between a pair of stop surfaces 211. Elastic means 212 may be arranged between the profile and at least one stop surface to dampen the sliding of the anchoring profile 10 along the Y axis.

[0024] The system may further comprise a connecting profile 100 connected to the end 3 of the roller blind 2. The connecting profile 100 may be configured to allow the roller blind to be used with the anchoring profile 10. Preferably, the anchoring profile 10 and the connecting profile 100 are mutually configured to allow mutual sliding along the longitudinal axis Z. For example, the fastening profile 10 may be fixed, whereas the profile 100 (and therefore also the roller blind) is movable within the anchoring profile 10 when the roller blind is collected / rolled up.

[0025] The anchoring profile 10 can therefore comprise a seat 20. As will be explained in more detail below, the connecting profile 100 can be at least partially inserted into the seat 20 to slide therein. The fastening profile 10 can therefore form a guide rail for the connecting profile 100.

[0026] According to a particular aspect of the invention, the anchoring profile can be designed to accommodate differently shaped connecting profiles 100. This feature makes it possible to provide a system 1 with an anchoring profile 10 and, if appropriate, with a support profile 200, regardless of the configuration of the connecting profile 100 of the roller blind 2.

[0027] Advantageously, this can lead to a cost advantage for the production and storage of the system 1 and in particular the rails 10.

[0028] Furthermore, this may be advantageous for the operator installing System 1, provided that the operator can deploy it and, if necessary, attach it to the door or window regardless of the configuration of the blind.

[0029] Furthermore, the same rail can be adapted to blinds from different manufacturers or different types, for example different thicknesses, different colors, different properties such as hail resistance, sun resistance, etc.

[0030] Preferably, the rail 10 can be inserted into the support profile 200 to form a post 3. As shown schematically in Fig. As shown in Figure 12, the system may comprise a pair of profiles 200 with a corresponding pair of rails 10 to form a pair of posts 3. The roller blind 2 may comprise a pair of profiles 100, each arranged vertically on opposite sides and slidable within the rail 10.

[0031] The rail 10 may have a longitudinal extension along the Z axis.

[0032] In use, the Z axis can extend vertically and in the direction of travel of the roller blind 2. The rail can comprise an elongated seat 20, such a seat 20 can define the Z axis. The rail 10 can have an opening 22. The opening can also have a longitudinal extension along an axis parallel to the Z axis. Such an opening can be designed to allow the passage of the roller blind 2 and / or the connecting profile 100 when the profile 100 is inserted into the seat 20. The rail can have a substantially rectangular cross-section. The rail can therefore define a cross-sectional plane XY that extends substantially perpendicular to the Z axis.

[0033] Conveniently, a pair of median planes may be provided, each extending along the Y-axis and the X-axis and longitudinally along the Z-axis. In other words, a median plane defined by the XZ axes and a perpendicular median plane defined by the YZ axes may be provided.

[0034] For convenience of description, reference is made below to the sections shown in the accompanying drawings, in which the Y-axis is the vertical axis and the X-axis is the horizontal axis, so that in effect reference is made to the vertical plane (YZ) and the horizontal plane (XZ).

[0035] The rail 10 may therefore comprise an upper part 11, which may have an opening 22. Conveniently, the opening 22 may have a width sufficient to accommodate the roller blind 2 (and / or part of the profile 100) in the opening. More specifically, the width of the opening 22 may be slightly larger than the roller blind 2 to allow the latter to slide in the opening 22 due to the sliding of the roller blind 2.

[0036] Part 11 may be Fig. 1A may be an upper one. However, it is clear that part 11 can be oriented in any conceivable manner. Preferably, the system 1 can be configured in the installed position such that part 11 faces the roller blind 2 and is therefore arranged opposite the frame or frame of the door or window.

[0037] The rail 10 may comprise a part 12 arranged opposite the part 11, for example a lower part (see Fig. 1A), the part 12 can face the frame of the door or window in the position of use. The part 12 can be inserted into the profile 200. Preferably, the entire rail 10 can be inserted into the profile 200, as shown, for example, in Fig. 10 is shown

[0038] The part 11 may comprise a pair of walls 13, 13' facing each other and spaced apart from each other. The distance d1 between the walls 13, 13' may define the width of the opening 22.

[0039] Advantageously, the walls 13, 13' can guide the roller blind 2 (and / or part of the profile 100) during the sliding of the roller blind 2. The winches 13, 13' can therefore serve as two guide rails for the roller blind 2 or for the profile 100.

[0040] The walls 13, 13' may extend substantially parallel to the Z-axis. More specifically, the walls 13, 13' may extend parallel to the vertical median plane (YZ).

[0041] The space between the walls 13, 13' can define a longitudinal groove 22', which can have guide walls. Such a longitudinal groove 22' can further comprise or define an opening 22.

[0042] The seat 20 may have an opening 22.

[0043] In other words, the part 11 may comprise a pair of elements 14, 14' facing each other. The elements 14, 14' may each comprise the wall 13, 13'. The seat 20 may comprise at least one stop region 29, 29', preferably a pair of stop regions 29, 29'. Such stop regions 29, 29' may be stop regions designed to come into contact with the connecting profile 100.

[0044] Suitably, the area 29, 29' or areas 29, 29' may be located near the opening 22. Thanks to these features, the seat 20 can be dimensioned differently along the X-axis (width L) and along the Y-axis (height H) while ensuring that the connecting profile 100 is retained in the seat 20, i.e., that the profile 100 does not detach when pulled by the roller blind 2, for example due to the action of wind.

[0045] In this way, the seat 20 can accommodate a connecting profile 100 of different shape and / or size and as a result, the same rail 10 can accommodate different profiles 100.

[0046] Furthermore, due to a pull on the roller blind 2 and the consequent sliding of the connecting profile 100 along the Y axis, contact between the latter and the areas 29, 29' near the Y axis can be ensured. In other words, the distance between the pulling force along the Y axis and the resisting force along the areas 29, 29' can be minimal. This feature prevents the profile 100 from deforming and slipping out of the seat 20.

[0047] More specifically, the regions 29, 29' can be arranged opposite one another. The regions 29, 29' can be arranged near the opening 22. Preferably, the regions 29, 29 can be spaced at an equal distance from one another. The space between the stop regions 29, 29' can define the opening.

[0048] The distance D1 can be approximately 0.5 to 5 mm.

[0049] Conveniently, the width of the seat 20 may be greater than or much greater than the distance d1. In this way, as explained above, different profiles 100 can be accommodated in the same seat 20 without compromising the resistance to disengagement.

[0050] According to a particular aspect of the invention, the stop surfaces 29, 29' can be substantially convex, for example, curved, as shown in the accompanying figures, or cup-shaped or angular. In this way, the contact between the profile 100 and the stop area 29, 29' can be suitably tapered, maximizing the effect near the Y axis.

[0051] Preferably, the regions 29, 29' are curved. This can serve to prevent the connecting profile 100 from being damaged by impact with the regions 29, 29'.

[0052] The seat 20 may include a pair of upper surfaces 21, 21' disposed on opposite sides with respect to the opening 22.

[0053] Such upper surfaces 21,21' may include stop areas 29,29'.

[0054] The upper surfaces 21,21' may comprise a flat area 28,28'.

[0055] Preferably, the elements 14,14' may comprise the respective surfaces 21,21' and therefore also the curved regions 29,29' and the flat regions 28,28'.

[0056] According to a particular aspect of the invention, the flat regions 28, 28' can be arranged inclined with respect to the X-axis.

[0057] Suitably, the flat areas 28, 28' can adjoin the convex stop areas 29, 29'. In this way, the effect on the profile 100 described above is particularly effective.

[0058] In this way, the convex areas 29,29' can be particularly effective even in the case of long profiles 100.

[0059] More precisely, the planar regions 28,28' may be arranged in an inclined plane π with respect to the plane XZ, as shown for example in Fig. 1A is shown.

[0060] Preferably, the inclination of the plane π can be between 5° and 45°. In particular, the inclination can be more than 5° to achieve high resistance efficiency, and less than 45° to limit the overall dimensions.

[0061] Preferably, the inclination can be approximately 30°. This can achieve an optimum between the properties described above.

[0062] The above can ensure that different designed connecting profiles 100 can be effectively accommodated. For example, profiles 100 with a larger width ( Fig. 5, Fig. 15 and Fig. 7), symmetrical or asymmetrical profiles 100 (for example Fig. 6, Fig. 16, Fig. 5, Fig. 15), shaped profiles 100 with inclined surfaces (for example Fig. 3, Fig. 4 Fig. 13), round profiles ( Fig. 4, Fig. 4 Fig. 14).

[0063] In fact, in any case, the regions 29, 29' may come into contact with the profile 100 to retain it. As will be explained in more detail below, the regions 29, 29' may come into contact with at least one or more stop surfaces 110, 110' of the profile 100.

[0064] The profiles can be made of a metal, for example as profiles 100 designed in the manner of a zipper, as shown in the Fig. 5, Fig. 6, Fig. 15 and Fig. 16. The profiles 100 can be formed from a polymer, preferably from an elastomeric polymer, preferably a TPE, as shown in the Fig. 3, Fig. 13, Fig. 4, Fig. 14 and Fig. 7 is shown.

[0065] The profiles 100 may include a part 120 designed to be connected to the roller blind 2. This part may be substantially planar.

[0066] The profiles 100 may comprise a shaped part 121. The latter may be inserted into the seat 20. In particular, the part 121 may have various configurations while being effectively retained in the seat 20 of the same rail 10.

[0067] The part 121 may have at least one surface 110 configured to abut against at least one of the stop regions 29, 29'. This may ensure that the part 121 disengages from the seat 20 and thus that the profile 100 disengages from the rail 10.

[0068] The Fig. 3 and Fig. 13 shows a connecting profile 100 in which the region 121 has a pair of inclined surfaces 110, 110' designed to bear against the convex regions 29, 29'. The surfaces 110, 110' can be inclined in the same manner as the regions 28, 28'. Conveniently, such a part can have a pair of concave regions 111, 111, 111' arranged near the part 120.

[0069] If the profile 100 is pulled in the direction of the Y axis, the concave areas 111,111' may strike against the convex areas 29,29', so that the resistance is particularly high.

[0070] In fact, in case of high tension, the profiles 100 can be slightly deformed until the concave areas 111, 111' abut against the convex areas 29, 29', thus generating a high resistance.

[0071] Fig. 4 and Fig. 14 shows a profile 100 in which the part 121 has a substantially circular cross-section. In this case, a pair of sections 110, 110' opposite the region 120 of the outer surface of the circular part define the stop surfaces 110, 110'.

[0072] Although the Fig. 4 is offset from the upper surface 23, 23', the part 121 can be compressed under tensile load and can slide until the areas 110, 110' strike against the areas 29, 29'.

[0073] Fig. 5 and Fig. 15 shows a profile 100 in which part 121 is designed as a zipper or includes one. In this case, the zipper can be arranged on the left or right depending on the size of the seat 20.

[0074] In any case, the part 121 may comprise an upper surface 110 which may abut against one of the stop regions 29, 29'.

[0075] Fig. 5 and Fig. 6 show a profile 100 in which part 121 comprises or consists of a zipper. In particular, the latter can be symmetrical and therefore comprise a pair of surfaces 110, 110' that can abut against the regions 29, 29'.

[0076] It is clear that the profile 100 and / or the part 121 may have different configurations not shown in the attached figures.

[0077] The seat 20 may include a lower floor surface 31.

[0078] The distance between the upper surface 21 and the surface 31 can define the height H. More precisely, if beveled areas 28, 28' are provided there, the distance between the convex areas 29, 29' can define the height H of the seat 20.

[0079] The lateral surfaces 41,41' may extend substantially parallel to the plane YZ.

[0080] The distance between the lateral surfaces 41,41' can essentially define the width L of the seat 20.

[0081] In the embodiment shown in Fig. 13, Fig. 14, Fig. 15 and Fig. As shown in Figure 16, the lateral surfaces 41, 41 can be substantially continuous. Optionally, they can extend slightly divergently with respect to the vertical plane YZ.

[0082] In this case, the seat 20 can be particularly large and adapted to accommodate profiles 100 of different configurations.

[0083] The width L can be defined as the distance between the lateral surfaces 41, 41'. For example, the width L can be greater than 10 mm.

[0084] The height H can be more than 20 mm.

[0085] Furthermore, in such an embodiment, the rail 10 can be particularly easy to provide.

[0086] In fact, this can be provided by a single extrusion defining the rail 10 and the seat 20 as well as the opening 22.

[0087] According to a particular embodiment, the rail 10 can be designed to receive substantially T-shaped profiles.

[0088] The profile 100 may include a substantially planar portion 120 and a planar portion 121. These portions 120, 121 may extend substantially perpendicular to each other to define the T-shape. Therefore, the portion 121 may include a lower surface 122 and a pair of upper surfaces 123, 123' disposed on opposite sides of the portion 120. The portion 121 may further include a pair of end portions 124, 124'.

[0089] The distance between the end areas 124,124' can define the width L2 of the profiles 100

[0090] When the part 121 is received in the seat 20, the upper surfaces 123, 123' may face or abut against the surfaces 21, 21'. More specifically, at least a portion 110, 110' of the upper surfaces 123, 123' may abut against the regions 29, 29'.

[0091] The section 110,110' can be arranged close to the part 120. This makes it possible to provide high tensile strength along the Y axis.

[0092] Conveniently, the seat may be designed to define a pair of further contact areas 42, 42', as shown, for example, in the Fig. 1A and Fig. 2 is shown.

[0093] The contact areas 42, 42' may be offset from the contact areas 29, 29' to define a seat 20' for the part 121. It is clear that the seat 20 may encompass the seat 20'.

[0094] In particular, the contact areas 42, 42' and 29, 29' can come into contact with the part 121 on opposite sides. The areas 42, 42' with the surface 122 and the areas 29, 29' with the surface 121, 121', preferably with the section 124, 124'.

[0095] The lateral surfaces 41, 41' may be the contact areas 42, 42'. The latter may have pointed or convex areas, preferably curved areas, similar to the areas 29, 29'.

[0096] In this way, the part 121 can be effectively retained in the seat 20'. Should the profiles 100 be subjected to tensile stress in the Y-axis direction, the part 121 will strike the areas 29, 29' and will therefore tend to bend the ends 124, 124', causing the surface 122 to come into contact with the areas 42, 42'.

[0097] More specifically, the lateral surfaces 41,41' may comprise a region 43,43' and a region 44,44' arranged on opposite sides with respect to the stop region 42,42'.

[0098] The regions 43, 43' may face one another and be arranged at a distance d3. The regions 42, 42' may face one another and be arranged at a distance d2. Advantageously, the distance d3 is greater than the distance d2, so that a flat region 45, 45' is defined, which is arranged between the region 43, 43' and the region 42, 42'.

[0099] For example, the distance d2 can be between 20 and 25 mm. The distance d2 can be between 10 and 15 mm.

[0100] According to a particular aspect of the invention, the distance d2 may be at least three times greater than the distance d1. In this case, the seat 20 may have a large width L.

[0101] The seat 20' can therefore be limited by the area 42, 42', by the flat area 45, 45', by the flat area 43, 43', and by the upper surface 121, 121'. This ensures that if the profile 100 is pulled in the direction of the Y-axis, the flat area 45, 45' also defines a stop area 42, 42'.

[0102] Fig. Figure 9, for example, schematically shows the process in which the profile of the roller blind 2 is deformed due to tension. In this case, part 121 can be deformed. The regions 110, 110' can advantageously abut against the regions 29, 29' near part 120, while the ends 124, 124' can abut against the surface 42, 42, in particular against the surface 45, 45', which thus acts as a stop surface.

[0103] Preferably, the region 43, 43' may be substantially parallel to the YZ plane, which extends vertically with reference to the accompanying figures. Preferably, the region 45, 45' may extend substantially parallel to the XZ plane, which extends horizontally with reference to the accompanying figures.

[0104] The areas 44,44' may extend substantially vertically or slightly divergently, as shown, for example, in the Fig. 1A and Fig. 2. In this way, the seat 20 can be dimensioned the same size, so that the rail 10 can be used with the T-shaped profile 100 or with other profiles 100 as described above.

[0105] Regardless of the configuration of the surfaces 41, 41' and in particular of the presence of the stop areas 42, 42', the rail 10 can be configured such that it deforms due to a pull on the roller blind 2.

[0106] In particular, due to a pull on the roller blind 2, the profile 100 may strike against the rail 10, which may be configured so that the areas 29,29' may be brought closer to each other.

[0107] This feature also allows to prevent the profile 100 from coming out of the seat 20.

[0108] The element 14, 14' can therefore each have a weakened region 16, 16' to act as a pin. Preferably, the region 16, 16' can be provided in a side wall 41, 41'. The region 16, 16' can preferably be provided in a vertical wall 43, 43'.

[0109] More specifically, the element 14, 14' may include a portion having a smaller thickness and defining a weakened region 16, 16'. For example, the thickness S in the region 16, 16' may be less than the thickness of the wall 41, 41'.

[0110] For example, with reference to the Fig. 8A, the wall 41,41' may have the region 16,16' with a smaller thickness than the wall 43.

[0111] On the other hand, the area 16,16' can be arranged at a different position. Fig. 9, for example, shows the wall 41,41' with a region of reduced thickness in the wall 45.

[0112] In any case, a pull on the roller blind can cause the rotation of the element 14,14' around the area 16,16', so that the stop areas 29,29' move towards each other.

[0113] In particular, the outward rotation of the element 14, 14' can cause a portion 15, 15' of the wall 13, 13' to approach. Such a portion 15, 15' can preferably be provided near the regions 29, 29'. Optionally, the latter can encompass the portion 15, 15'.

[0114] In this way, the sections 15, 15' can abut against a corresponding area 115, 115' of the roller blind 2 and / or the part 120 of the profile 200.

[0115] For example, Fig. 8B schematically shows the rail 10 before its deformation (dashed line) and after its deformation, in which the elements 14,14' are rotated outwards and the regions 15,15' are in contact with the regions 115,115'.

[0116] Due to a pull on the roller blind 2 and thus on the profile 100, this feature allows a closing effect of the rail 10 on the connecting profile 100. It is clear that such an effect can also be achieved in other ways.

[0117] The invention can be implemented with countless modifications and variations, all of which fall within the inventive principle as set forth in the appended claims. All details may be replaced by other technically equivalent elements, and the materials may be different as needed, without departing from the scope of the invention.

[0118] Although the invention has been explained above with particular reference to the accompanying figures, the reference numerals used in the description and in the claims are intended only to improve readability and understanding of the invention and therefore do not limit the scope of the claimed invention.
