Description

[0001] ANCHORING PROFILE USABLE IN AN ANCHORING SYSTEM OF A ROLLER BLIND TO A DOOR OR WINDOW

[0002] DESCRIPTION

[0003] Field of the invention

[0004] The present invention generally relates to the technical field of system for anchoring a blind to a support structure such as door or window, and it particularly relates to an anchoring profile which can be used in such system.

[0005] State of the Art

[0006] Systems for anchoring roller blinds to load-bearing structures such as walls or frames for doors or windows are known. The blinds generally have connection profiles fixed at the vertical and horizontal end edges. Such connection profiles are for example in the form of zips or shaped polymeric profiles.

[0007] On the other hand the anchoring systems comprise a longitudinal support profile fixed to the wall or frame, for example by means of screws, generally U-shaped and an anchoring profile, generally also referred to as rail, arranged internally in the fixed support profile.

[0008] The connection profile of the end of the blind is therefore slidably connected with the rail so as to allow the sliding of the blind, for example in case of roller blinds to allow to raise / lower the blind, and at the same time ensure that the blind remains fixed to the support profile, that is prevent the pulling of the blind from promoting the disengagement of the connection profile from the rail.

[0009] To this end, the rail therefore comprises a longitudinal seat within which there slides the connection profile of the end of the blind.

[0010] The prior art anchoring profiles (rai ls have a counter-shaped seat with respect to the connection profile of the end of the blind. Therefore, each anchoring system of the blind requires a specific connection profile and a specific anchoring profile or rail.

[0011] Such aspect is amplified by the fact that no standard is provided for and the market has a high number of different connection profiles.

[0012] Such drawback is particularly burdensome given that the companies which provide the drapes of the blind with the connection profiles are different with respect to the companies which offer the rails and the support profiles, which are generally aluminium extrusions. This requires a necessary limitation of the anchoring system and entails increased costs both for producers of profiles, who must previously receive specific instructions on their geometry, and for installers of systems who must ensure that all the parts are complementary.

[0013] Minor dimensional errors cause the exit of the connection profile and therefore they not ensure the anchoring of the blind and / or difficulty in sliding the blind.

[0014] Summary of the invention

[0015] An object of the present invention is to at least partly overcome the aforementioned drawbacks, by providing an anchoring profile that is highly functional and cost-effective.

[0016] Another object of the present invention is to provide a versatile anchoring profile.

[0017] Another object of the present invention is to provide an anchoring profile that is highly slidable.

[0018] Another object of the present invention is to provide an anchoring profile that is highly resistant.

[0019] These and other objects that will be more apparent hereinafter, are attained by an anchoring profile and / or by a system comprising such anchoring profile as described and / or claimed and / or illustrated herein.

[0020] Advantageous embodiments of the invention are defined according to the dependent claims.

[0032] Detailed description of some preferred embodiments

[0033] With reference to the mentioned figures, herein described is a protection system 1 which can be installed at an opening such as a window or a door.

[0034] Essentially, the system 1 may comprise a blind 2. The system 1 may be a system for protecting from then sun and / or prying eyes depending on the configuration of the blind 2.

[0035] The system 1 may therefore comprise a winder roller 5 for rolling the blind 2 of the per se known type, for example as schematically shown in FIG. 12.

[0036] The system 1 may further comprise at least one support profile 200 designed to be fixed to the door or window. Preferably, the support profile 200 may be fixed to the door or window along the sliding direction of the blind, for example vertically.

[0037] It is clear that the system 1 may comprise a pair of support profiles 200 to form a pair of uprights.

[0038] Advantageously, there may be provided for at least one anchoring profile 10. Hereinafter, such anchoring profile may be referred to as guide rail or rail.

[0039] The anchoring profile 10 may be fixed with the support profile 200. For example, the latter may be substantially U-shaped to internally define a seat designed to house the anchoring profile 10.

[0040] The anchoring profile 10 may be fixed with the support profile 200 in a per se known manner. For example, by means of springs, male or female elements or other similar systems.

[0041] Suitably, the anchoring profile 10 may be inserted into the support profile 200 and fixed thereto using suitable means 210, which may for example comprise abutment surfaces and / or springs and / or other fixing systems of the known type.

[0042] For example, FIG. 10 shows the anchoring profile 10 interposed between a pair of abutment surfaces 211. Possibly, there may be provided for elastic means 212 interposed between the profile and at least one of the abutment surfaces 211 to dampen the sliding of the anchoring profile 10 along the axis Y.

[0043] The system may further comprise a connection profile 100 fixed to the end 3 of the blind 2.

[0044] The connection profile 100 may therefore be configured to connect the blind with the anchoring profile 10. Preferably, the anchoring profile 10 and the connection profile 100 may be mutually configured to allow the mutual sliding along the longitudinal axis Z. For example, the fixing profile 10 may be fixed, while the profile 100 (and therefore the blind 2) may slide in the anchoring profile 10 when the blind is unrolled / rolled.

[0045] The anchoring profile 10 may therefore comprise a seat 20. As better explained hereinafter, the connection profile 100 may be at least partially inserted into the seat 20 to slide therein. The fixing profile 10 may therefore define a guide rail for the connection profile 100.

[0046] According to a particular aspect of the invention, the anchoring profile 10 may be configured to house differently shaped connection profiles 100.

[0047] This characteristic may allow to provide a system 1 with an anchoring profile 10 and possibly a support profile 200 irrespective of the configuration of the connection profile 100 of the blind 2.

[0048] Advantageously this may result in the advantage in terms of costs for producing and storing systems 1, and in particular rails 10.

[0049] Furthermore, this may result in the advantage for the operator who installs the system 1 given that the operator may provide it and possibly fix it to the door or window irrespective of the configuration of the blind.

[0050] Furthermore, the same rail 10 may be adapted with blinds of different manufacturers or of different types, for example thickness, colours, hail-proof, sun-proof, or others.

[0051] Preferably, the rail 10 may be inserted into the support profile 200 to form an upright 3. For example as schematically shown in FIG. 12, the system 1 may comprise a pair of profiles 200 with a respective pair of rails 10 to form a pair of uprights 3. The blind 2 may comprise a pair of profiles 100 arranged vertically on opposite sides and slidable in the rail 10.

[0052] The rail 10 may have a longitudinal extension along an axis Z.

[0053] In use, such axis Z may for example be vertical and it may be the sliding direction of the blind 2.

[0054] The rail 10 may comprise a longitudinal seat 20. Such seat 20 may define the axis Z.

[0055] The rail 10 may have an opening 22. The opening 22 may also have a longitudinal extension along an axis parallel to the axis Z.

[0056] Such opening 22 may be configured so as to allow the passage of the blind 2 and / or of the connection profile 100 once the profile 100 is inserted into the seat20.

[0057] The rail 10 may have a substantially rectangular cross-sectional shape. The rail 10 may therefore have a cross-sectional plane X-Y substantially perpendicular to the axis Z.

[0058] Suitably, there may be provided for a pair of median planes respectively lying in the axis Y and in the axis X which extend longitudinally along Z. In other words, there may be provided for a median plane defined by the axes X-Z and a perpendicular median plane defined by the axes Y-Z.

[0059] For the sake of description simplicity, hereinafter, reference will be made to sections shown in the attached images in which the axis Y is the vertical axis and the axis X is the horizontal axis, and as a result reference will be made to the vertical plane (Y-Z) and to the horizontal plane (X-Z).

[0060] The rail 10 may therefore comprise an upper portion 11 which may include the opening 22. Suitably, the opening 22 may have a width sufficient to allow to provide the blind (and / or a part of the profile 100) in the opening.

[0061] In greater detail, the width of the opening 22 may be slightly greater than the blind 2 so as to allow the sliding of the latter in the longitudinal opening 22 upon the sliding of the blind 2.

[0062] The portion 11 may be upper with reference to FIG. 1A. However, it is clear that in use the portion 11 may be oriented in any manner. Preferably, once installed, the system 1, the portion 11 may be the one facing the blind 2 and therefore opposite to the frame of the frame of the door or window.

[0063] The rail 10 may comprise a portion 12 opposite to the portion 11, for example a lower portion 12 with reference to FIG. 1A. The portion 12 in use may therefore be faced to the frame of the door or window. The portion 12 may be inserted into the profile 200.

[0064] Preferably, the entire rail 10 may be inserted into the profile 200, for example as shown in FIG. 10.

[0065] The portion 11 may comprise a pair of walls 13, 13' that are faced and spaced apart. The distance dl between the walls 13, 13' may define the width of the opening 22.

[0066] Advantageously, the walls 13, 13' may guide the slide 2 (and / or a part of the profile 100) during the sliding of the blind 2. The walls 13, 13' may therefore act as two guide rails for the blind 2, or for the profile 100.

[0067] The walls 13, 13' may be substantially parallel to the axis Z. In greater detail, the walls 13, 13' may be parallel to the vertical median plane (Y-Z).

[0068] The space between the walls 13, 13' may define a longitudinal groove 22' which may comprise the guide walls 13, 13'. Such groove 22' may further comprise or define the opening 22.

[0069] The seat 20 may comprise the opening 22.

[0070] In other words, the portion 11 may comprise a pair of elements 14, 14' that are mutually facing. The elements 14, 14' may comprise the respective wall 13, 13'.

[0071] Essentially, the seat 20 may comprise at least one abutment area 29, 29', preferably a pair of abutment areas 29, 29'. Such abutment areas 29, 29' may be abutment areas designed to come into contact with the connection profile 100.

[0072] Suitably, the area 29, 29' or the areas 29, 29' may be close to the opening 22.

[0073] Thanks to this characteristic, the seat 20 may be variously sized along the axis X (width L) and along the axis Y (height H) and at the same time ensure that the connection profile 100 is retained in the seat 20, that is the profile 100 is not disengaged when pulled by the blind 2, for example due to the action of the wind.

[0074] In this manner, the seat 20 may house connection profiles 100 with different shape and / or size, and as a result the same rail 10 may house the different profiles 100.

[0075] Furthermore, upon pulling the blind 2, and therefore the sliding of the connection profile 100 along the axis Y, the contact between the latter and the areas 29, 29' may occur close to such axis Y. In other words, the distance between the traction force along the axis Y and the resistant strength along the areas 29, 29' may be minimum. This characteristic may allow to prevent the profile 100 from exiting from the seat 20 by deformation.

[0076] In greater detail, the areas 29, 29' may be mutually faced. The areas 29, 29' may be close to the opening 22. Preferably, the areas 29, 29' may be spaced apart by a substantially equal distance dl. Possibly, the interspace between the abutment areas 29, 29' may define the opening 22.

[0077] The distance dl may measure about 0.5-5 mm.

[0078] Suitably, the width L of the seat 20 may be greater or much greater than the distance dl. In this manner, as explained above, different profiles 100 may be housed in the same seat 20 without jeopardising the resistance to disengagement.

[0079] According to a particular aspect of the invention, the abutment areas 29, 29' may be substantially convex, for example curved, as shown in the attached figures, or cusp-shaped or edge-shaped. In this manner, the contact between the profile 100 and the abutment area 29, 29' may be substantially sharp-pointed maximising the action near the axis Y.

[0080] Preferably, the areas 29, 29' may be curve-shaped. This may allow to prevent the impact between the connection profile 100 from being damaged impacting with the areas 29, 29'.

[0081] Essentially, the seat 20 may comprise a pair of upper surfaces 21, 21' arranged on opposite sides with respect to the opening 22.

[0082] Such upper surfaces 21, 21' may comprise abutment areas 29, 29'.

[0083] The upper surface 21, 21' may comprise a planar area 28, 28'.

[0084] Preferably, the elements 14, 14' may include the respective surfaces 21, 21' and therefore also the convex areas 29, 29' and the planar areas 28, 28'.

[0085] According to a particular aspect of the invention, advantageously, the planar areas 28,

[0086] 28' may be inclined with respect to axis X.

[0087] Suitably, the planar areas 28, 28' may be consecutive to the convex abutment areas 29, 29'. In this manner, the action of the latter on the profile 100 described above may be particularly effective.

[0088] In this manner, also in case of profiles 100 with great length, the convex areas 29, 29' may effectively act as described above.

[0089] In greater detail, the planar areas 28, 28' may lie in an inclined plane n with respect to the plane X-Z, for example as shown in FIG. 1A.

[0090] Preferably, the inclination of the plane n may be comprised between 5° and 45°. In particular, the inclination may be greater than 5° so as to ensure a high resistance effectiveness, and it may be less than 45° so as to limit the overall dimensions.

[0091] Preferably, the inclination may measure about 30°. This may allow for an excellent between the characteristics mentioned above.

[0092] The above may allow to effectively house the differently shaped connection profiles 100. For example, profiles 100 with great width (for example FIG. 5, FIG. 15 and FIG. 7), symmetrical or asymmetrical profiles 100 (for example FIG. 6, FIG. 16 and FIG. 5, FIG. 15), shaped profiles 100 with inclined surfaces (for example FIG. 3, FIG. 13), circular-shaped profiles 100 (FIG. 4, FIG. 14).

[0093] As a matter of fact, in any case, the areas 29, 29' may come into contact with the profile 100 to retain it. In greater detail, as better explained hereinafter, the areas 29, 29' may come into contact with at least one or more abutment surfaces 110, 110' of the profile 100.

[0094] The profiles 100 may be made of metal material, such as for example the zip-like profiles 100 shown in FIG. 5, FIG. 6, FIG. 15 and FIG. 16. The profiles 100 may be made of polymeric material, preferably elastomeric, preferably TPE, as shown in FIG. 3, FIG. 13, FIG. 4, FIG. 14, FIG. 7.

[0095] The profiles 100 may comprise a portion 120 designed to be fixed to the blind 2. Such portion 120 may be substantially planar.

[0096] The profiles 100 may comprise a shaped portion 121. The latter may be inserted into the seat 20. In particular, the portion 121 may have different configurations and it may be simultaneously effectively retained in the seat 20 of the same rail 10.

[0097] The portion 121may have at least one surface 110 designed to abut against at least one of the abutment areas 29, 29'. This may allow to prevent the disengagement of the portion 121 from the seat 20, and therefore the disengagement of the profile 100 from the rail 10.

[0098] FIG. 3 and FIG. 13 show a connection profile 100 in which the portion 121 comprises a pair of inclined surfaces 110, 110' designed to abut against the convex areas 29, 29'.

[0099] The surfaces 110, 110' may be inclined in a manner identical to the areas 28, 28'. Suitably, such portion 121 may comprise a pair of concave areas 111, 111' arranged near the portion 120.

[0100] Should the profile 100 be pulled along the axis Y, the concave areas 111, 111' may abut against the convex areas 29, 29' so that the traction resistance is particularly high.

[0101] As a matter of fact, in the event of high traction, the profile 100 may be slightly deformed until the concave areas 111, 111' abuts against the convex areas 29, 29' therefore providing a high resistance.

[0102] Such configuration may provide a particularly high tensile strength (along the axis Y) between the profile 100 and the rail 10. Therefore, this may allow to prevent the disengagement of the profile 100 from the rail 10.

[0103] FIG. 4 and FIG. 14 show a profile 100 in which the portion 121 has a substantially circular cross-sectional shape. In this case, a pair of opposite sections 110, 110' with respect to the portion 120 of the outer surface of the circular portion and it may define the abutment surfaces 110, 110'.

[0104] As a matter of fact, although in FIG. 4 the portion 121 is spaced from the upper surface 23, 23', in case of high traction, the portion 121 may be compressed and it may slide until the sections 110, 110' abut against the areas 29, 29'.

[0105] FIG. 5 and FIG. 15 show a profile 100 in which the portion 121 comprises or consists of a zip. In this case, thanks to the size of the seat 20, the zip may be left or right.

[0106] As a matter of fact, in any case, the portion 121 may comprise an upper surface 110 which may abut against one of the abutment areas 29, 29'.

[0107] FIG. 6 and FIG. 16 show a profile 100 in which the portion 121 comprises or consists of a zip. In particular, the latter may be of the symmetrical type and it may therefore comprise a pair of upper surfaces 110', 110 which may abut against the areas 29, 29'.

[0108] It is clear that the profile 100 and / or the portion 121 may have different configurations not shown in the attached figures.

[0109] The seat 20 may comprise a lower bottom surface 31.

[0110] The distance between the upper surface 21 and the surface 31 may define the height H. In greater detail, should there be inclined areas 28, 28' the distance between the convex areas 29, 29' may define the height H of the seat 20.

[0111] The seat 20 may comprise a pair of lateral surfaces 41, 41'.

[0112] The lateral surfaces 41, 41' may be substantially parallel to the plane Y-Z.

[0113] The distance between the lateral surfaces 41, 41' may substantially define the width L of the seat 20.

[0114] In the embodiments shown in FIG. 13, FIG. 14, FIG. 15 and FIG. 16 the lateral surfaces 41, 41' may be substantially continuous. Possibly, they may be slightly divergent with respect to the vertical plane Y-Z.

[0115] In this case the seat 20 may be particularly large in size and it may be adapted to house variously configured profiles 100.

[0116] The width L may be defined as the distance between the lateral surfaces 41, 41'. For example, the width L may be greater than 10 mm.

[0117] The height H may be greater than 20 mm.

[0118] Furthermore, in such embodiment the rail 10 may be particularly easy to provide. As a matter of fact, there may be provided a single extrusion which defines the rail 10 with the seat 20 and the opening 22.

[0119] According to a particular embodiment, the rail 10 may be configured to house substantially T-shaped profiles 20.

[0120] The profile 100 may comprise a s substantially planar portion 120 and a planar portion 121. Such portions 120, 121 may be substantially perpendicular so as to define the T-shape.

[0121] The portion 121 may therefore comprise a lower surface 122 and a pair of upper surfaces 123, 123' on opposite sides with respect to the portion 120. The portion 121 may further comprise a pair of end areas 124, 124'.

[0122] The distance between the end areas 124, 124' may define the width L2 of the profile

[0123] 100.

[0124] Once the portion 121 is housed in the seat 20, the upper surfaces 123, 123' may remain faced or abutting against the surfaces 21, 21'. In greater detail, at least one section 110, 110' of the upper surfaces 123, 123' may abut against the areas 29, 29'.

[0125] The section 110, 110' may be near the portion 120. This may allow to provide a high tensile strength along the axis Y.

[0126] Suitably, the seat 20 may be configured so as to define a pair of further contact areas 42, 42', for example as shown in FIG. 1A and in FIG. 2.

[0127] The contact areas 42, 42' may be spaced apart from the contact areas 29, 29' so as to define a seat 20' for the portion 121. It is clear that the seat 20 may include the seat 20'.

[0128] In particular, the contact areas 42, 42' e 29, 29' may come into contact with the portion 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'.

[0129] The lateral surfaces 41, 41' may comprise the contact areas 42, 42'. The latter may be pointed or convex areas, preferably curved, similarly to areas 29, 29'.

[0130] In this manner, the portion 121 may be effectively retained in the seat 20'. As a matter of fact, should the profile 100 be pulled along Y, the portion 121 will abut against the areas 29, 29' and it will tend to bend the ends 124, 124' so that the surface 122 comes into contact with the areas 42, 42'.

[0131] In greater detail, the lateral surface 41, 41', may comprise an area 43, 43' and an area 44, 44' arranged on opposite sides with respect to the abutment area 42, 42'.

[0132] The areas 43, 43' may be arranged facing and spaced apart by a distance d3. The areas 42, 42' may be arranged facing and spaced apart by a distance d2. Suitably, the distance d3 may be greater than the distance d2 so as to define a flat area 45, 45' interposed between the area 43, 43' and the area 42, 42'.

[0133] For example, the distance d2 may measure about 20-25 mm. The distance d3 may measure about 10-15 mm.

[0134] According to a particular aspect, the distance d2 may be at least 3 times greater than the distance dl. In this manner, the seat 20 may have a great width L.

[0135] The seat 20' may therefore be delimited by the area 42, 42', by the flat area 45, 45', by the flat area 43, 43' and by the upper surface 121, 121'.

[0136] In this manner, should the profile 100 be pulled along Y, also the flat area 45, 45' may define the abutment area 42, 42'.

[0137] For example, FIG. 9 schematically shows an operative step in which the profile of the blind 2 is deformed following traction. In this case, the portion 121 may be deformed. Advantageously, the areas 110, 110' near the portion 120 may abut against the areas 29, 29', while the ends 124, 124' may abut against the surface 42, 42', in particular against the surface 45, 45' which may therefore act as an abutment surface.

[0138] Preferably, the area 43, 43' may be substantially parallel to the plane Y-Z, that is substantially vertical with reference to the attached figures. Preferably, the area 45, 45' may be substantially parallel to the plane X-Z, that is substantially horizontal with reference to the attached figures.

[0139] The area 44, 44' may be substantially vertical or slightly divergent for example as shown in FIG. 1A and FIG. 2. In this manner, the seat 20 may be equally large in size so that the rail 10 can be used with the T-shaped profile 100 or with other profiles 100 as described above.

[0140] Irrespective of the configuration of the surfaces 41, 41' and in particular of the presence of abutment areas 42, 42', the rail 10 may be configured so as to be deformed upon pulling the blind 2.

[0141] In particular, upon pulling the blind, the profile 100 may abut against the rail 10 which may be configured so that the portions 29, 29' may be mutually approached.

[0142] This characteristic may further allow to prevent the profile 100 from exiting from the seat 20.

[0143] The element 14, 14' may therefore comprise a respective weakening area 16, 16' so as to act as a pin. Preferably, the area 16, 16' may be at the side wall 41, 41'.

[0144] The area 16, 16' may preferably be at the vertical wall 43, 43'.

[0145] In greater detail, the element 14, 14' may have a section with a smallerthickness which may define the weakening area 16, 16'. For example, the thickness S at the area 16, 16' may be smaller than the thickness of the wall 41, 41'.

[0146] For example with reference to FIG. 8A, the wall 41, 41' may have the area 16, 16' with low thickness at the wall 43.

[0147] On the other hand, the area 16, 16' may be arranged at a different position. For example FIG. 9 shows the wall 41, 41' with the low thickness area arranged at the wall 45.

[0148] In any case, the pulling of the blind may promote the rotation of the element 14, 14' around the area 16, 16' and as a result the mutual approaching of the abutment areas 29, 29'. In greater detail, the outward rotation of the element 14, 14' may promote the approaching of a section 15, 15' of the wall 13, 13'. Such section 15, 15' may preferably be near the areas 29, 29'. Possibly, the latter may comprise the section 15, 15'.

[0149] In this manner, the sections 15, 15' may abut against a corresponding area 115, 115' of the blind 2 and / or the portion 120 of the profile 100.

[0150] For example, FIG. 8B schematically shows the rail 10 prior to the deformation (dashed line) and after the deformation thereof in which the elements 14, 14' are rotated outwards and the areas 15, 15' are in contact with the areas 115, 115'.

[0151] Upon pulling the blind 2, and therefore the profile 100, this characteristic may allow to have a closing effect of the rail 10 on the connection profile 100. It is clear that such effect may be obtained in a different manner.

[0152] The invention is susceptible to numerous modifications and variants all falling within the inventive concept outlined in the attached claims. All details can be replaced by other technically equivalent elements, and the materials can be different depending on the needs, without departing from the scope of protection of the invention.

[0153] Even though the invention has been described with particular reference to the attached figures, the reference numbers utilised in the description and in the claims are meant for improving the intelligibility of the invention and thus do not limit the claimed scope of protection in any manner whatsoever.
