Roller shutter curtain

Description

[0001] The invention relates to a roller shutter curtain, comprising a plurality of support profiles and a plurality of cover profiles, wherein a first cover profile is pivotally connected to a first support profile via a first hinge and wherein the first cover profile is pivotally connected to a second support profile via a second hinge.

[0002] A roller shutter curtain is generally known, for example, from EP 3 263 826 A1 or EP 2 039 871 A1. Regarding the feasibility and possible designs of the slats, the roller shutter curtain, or the roller shutter, reference is made to EP 2 039 871 A1.

[0003] EP 3 263 826 A1 discloses a roller shutter curtain comprising a plurality of support profiles and a plurality of panel profiles, wherein a first panel profile is pivotally connected to a first support profile via a first hinge, wherein the first hinge has a first panel hook of the first panel profile curved in the direction of the panel profile front side and a first support hook of the first support profile curved in the same direction as the first panel hook, wherein the first panel hook and the first support hook interlock, wherein the first panel hook is arranged at an upper end region of the first panel profile and the first support hook is arranged at a lower end region of the first support profile, and wherein the first panel profile is pivotally connected to a second support profile via a second hinge, wherein the second hinge has a second panel hook of the first panel profile curved in the direction of the panel profile rear side,wherein the second panel hook is arranged at an upper end region of the first panel profile. 1,

[0004] The disadvantage is that the shutter profiles can only be opened once the roller shutter curtain is fully lowered. This significantly limits their functionality, for example, as a sunshade.

[0005] It is therefore an object of the invention to provide a roller shutter curtain and a method for lowering a roller shutter curtain, which improves the functionality as a sun protection.

[0006] This problem is solved by the device and the method of the independent claims.

[0007] According to the invention, the roller shutter curtain has several support profiles and several panel profiles.

[0008] A first panel profile is pivotally connected to a first support profile via a first hinge.

[0009] The first hinge has a first panel hook of the first panel profile curved in the direction of the panel profile front side and a first support hook of the first support profile curved in the same direction as the first panel hook.

[0010] When opened, the front of the panel profile corresponds to the top of the panel profile.

[0011] The first panel profile thus has a first panel hook. The first panel hook is arranged at an upper end area of the panel profile.

[0012] The first support profile has a first support hook. The first support hook is arranged at a lower end region of the support profile.

[0013] Together, the first panel hook and the first support hook form the first hinge.

[0014] The first panel hook and the first support hook are curved in the same sense, i.e. in the same direction, e.g. clockwise or counterclockwise.

[0015] The first panel hook and the first support hook interlock. Preferably, the first panel hook and the first support hook always interlock, for example, regardless of whether the panel profile is open or closed. Preferably, the first panel hook rests on the first support hook. The support point defines, for example, a first, preferably fixed, pivot point.

[0016] The first panel profile is pivotally connected to a second support profile via a second hinge.

[0017] The second hinge has a second panel hook of the first panel profile curved in the direction of the panel profile rear side and a second support hook of the second support profile curved in the same direction as the second panel hook.

[0018] When opened, the back of the panel profile corresponds to the underside of the panel profile.

[0019] The first panel profile thus has a second panel hook. The second panel hook is located at an upper end area of the panel profile.

[0020] The second support profile has a second support hook. The second support hook is located at an upper end region of the support profile.

[0021] Preferably, the support profile can have a first and a second support hook.

[0022] Together, the second panel hook and the second support hook form the second hinge.

[0023] The second panel hook and the second support hook are curved in the same sense, i.e. in the same direction, e.g. counterclockwise or clockwise.

[0024] The first panel and support hooks are curved in the opposite direction to the second panel and support hooks.

[0025] The second panel hook and the second support hook interlock. Preferably, the second panel hook and the second support hook always interlock, for example, regardless of whether the panel profile is open or closed. Preferably, the second support hook rests on the second panel hook. The support point defines, for example, a second, preferably fixed, pivot point.

[0026] A support profile and a cover profile can each together form a louvre. For example, the first cover profile and the second support profile can be considered a louvre.

[0027] Preferably, at least two adjacent support profiles, e.g. the first support profile and the second support profile, can be constructed identically.

[0028] Alternatively or additionally, for example, at least two adjacent panel profiles can be constructed identically.

[0029] Preferably, both adjacent support profiles and adjacent panel profiles, and thus adjacent slats, are constructed identically, at least in a central area. In an upper and lower area, however, slats can be provided without adjustable panel profiles. For example, the lower and / or upper one, two, three, four, five, or more slats can be constructed without adjustable panel profiles.

[0030] The support profile and / or the cover profile can, for example, have a height between 3 cm and 6 cm, preferably 3.7 cm. The width can, for example, be between 0.5 cm and 1.5 cm, preferably 0.8 cm. The length can be adapted to the width of a window or door. For example, lengths between 30 cm and 380 cm, preferably between 40 cm and 250 cm, are conceivable.

[0031] Preferably, the first and / or second hinge can extend over the entire length. For example, the first and / or second hinge can have a slotted guide or be designed as a slotted guide.

[0032] The two hinges, preferably the distance between them, and the orientation of the hooks result in a comparatively large lever relative to the width of the slats. At the same time, a compact design is possible.

[0033] Furthermore, the arrangement and orientation of the hinges and hooks ensures that the shutter profiles are already open when the blind is lowered. This means that the roller shutter extends from the shutter box with the shutter profiles already extended.

[0034] For example, the slats can be guided vertically by side rails.

[0035] In order to enable the panel profile to be pivoted, it can preferably have lateral recesses in the area of the side rails.

[0036] The roller shutter box can, for example, comprise or consist of an aluminum and / or plastic material, e.g. rigid foam.

[0037] The drive can be via a belt and / or crank mechanism, for example. In addition to wired motor drives, radio-controlled motor drives are also conceivable.

[0038] Preferably, the drive drives a shaft which is connected to the roller shutter curtain.

[0039] The large opening angle allows for visibility and lets light, such as daylight, in. This ensures optimal sun protection in any position.

[0040] When the end strip of the roller shutter is in place, the shutter profiles begin to close from bottom to top. This provides privacy in the lower area while allowing light and / or air to enter the upper area.

[0041] In the closed position, the roller shutter contributes to thermal insulation and provides complete privacy. The slats are extremely stable, both in the open and closed positions. This ensures weather resistance and enhances safety.

[0042] Further developments of the invention can also be found in the dependent claims, the description and the accompanying drawings.

[0043] According to one embodiment, the first panel hook always rests on the first support hook, preferably when the panel profile is open and closed.

[0044] The support point defines, for example, a first, preferably fixed, pivot point.

[0045] The first panel hook and the first support hook always touch and / or are always engaged.

[0046] According to a further embodiment, the second support hook always rests on the second panel hook, preferably when the panel profile is open and closed.

[0047] The support point defines, for example, a second, preferably fixed, pivot point.

[0048] The second panel hook and the second support hook always touch and / or are always engaged.

[0049] According to a further embodiment, the pivot point of the first hinge and the pivot point of the second hinge are arranged offset from one another in the horizontal and / or vertical direction.

[0050] Preferably, the hinges are offset from each other both horizontally and vertically.

[0051] This results in a comparatively large lever relative to the width of the slats. At the same time, a compact design is possible.

[0052] The horizontal offset also ensures safe opening and / or closing of the panel profile.

[0053] The distance in the horizontal direction between the first hinge and the second hinge is preferably larger when the panel profiles are closed than when the panel profiles are open.

[0054] Preferably, the distance in the vertical direction between the first hinge and the second hinge is smaller when the panel profiles are closed than when the panel profiles are open.

[0055] According to a further embodiment, the first hinge has a stop of the first support profile arranged on the back of the support profile.

[0056] The stop serves, for example, to limit the pivoting movement between the first panel profile and the first support profile or to prevent the panel profile and / or the support profile from accidentally detaching from the first hinge.

[0057] The support profile thus has a stop which forms part of the first hinge.

[0058] Preferably, the support profile is formed integrally with the stop.

[0059] According to a further embodiment, the second hinge has a stop of the first panel profile arranged on the rear side of the panel profile.

[0060] The stop serves, for example, to limit the pivoting movement between the first cover profile and the second support profile or to prevent the cover profile and / or the support profile from accidentally detaching from the second hinge.

[0061] The panel profile thus has a stop which forms part of the second hinge.

[0062] Preferably, the cover profile is formed in one piece with the stop.

[0063] For example, the stop may have or consist of a projection, e.g. a nose.

[0064] The stop determines the maximum opening angle between the panel profile and the support profile. This can preferably be less than 90°, 80°, 70°, 60°, or 55°. For example, the opening angle can be 50°.

[0065] According to a further embodiment, at least one panel profile is formed in one piece with a first and / or second panel hook.

[0066] For example, the first and / or second panel hook can be formed on the panel profile.

[0067] Preferably, the entire panel profile, including the first and / or second panel hook, is rigid. This ensures that the entire panel profile is always pivoted.

[0068] According to a further embodiment, at least one support profile is formed in one piece with a first and / or second support hook.

[0069] For example, the first and / or second support hook can be formed on the support profile.

[0070] Preferably, the entire support profile including the first and / or second support hook is rigid.

[0071] According to a further embodiment, at least one carrier profile has at least one recess.

[0072] The recess can be rectangular, oval and / or round, for example.

[0073] Preferably, the recess serves as ventilation and / or as a passage for light.

[0074] The recess can, for example, be grilled. The grille forms an integrated insect screen. For example, the grille can include or consist of a metal mesh, e.g., wire and / or stainless steel mesh.

[0075] According to a further embodiment, the support profiles and / or cover profiles comprise or consist of a metal material, preferably aluminum material.

[0076] The support profile and / or the panel profile can be designed, for example, as extruded aluminum profiles. These can preferably be extruded and / or powder-coated aluminum profiles. Roll-formed aluminum and / or wet-painted aluminum are also conceivable.

[0077] This enables cost-effective production. For example, the hook structure can also be easily pressed into place.

[0078] According to a further embodiment, a lateral stop is provided which limits a relative movement between the first panel profile and the first support profile and / or between the first panel profile and the second support profile in the horizontal direction.

[0079] For example, the support profile can have grooves, preferably oriented parallel to one another, which can extend, for example, over the entire length.

[0080] The lateral stop can preferably be inserted into these grooves. For this purpose, the lateral stop can be provided with sliding blocks, e.g., lugs.

[0081] Alternatively, or additionally, a mesh screen can be mounted in the grooves to serve as an insect screen. The mesh can be secured using the inserted lateral stop. This prevents the mesh from shifting sideways.

[0082] The lateral stop can, for example, be designed as a plastic profile.

[0083] When the roller shutter is rolled up, the side stop can, for example, prevent the slats from touching one another, which could cause scratches, abrasions, and / or damage. The side stop can therefore serve a dual function.

[0084] According to another embodiment, the panel profiles are opened when the roller shutter curtain is lowered.

[0085] The hinges, in conjunction with gravity, ensure that the panel profiles are in the upright position.

[0086] Light can thus enter through the slats.

[0087] According to a further embodiment, the roller shutter curtain is designed in such a way that the panel profiles are closed from bottom to top when a lower end stop is reached.

[0088] The cover profiles are pressed together from bottom to top.

[0089] When the end strip of the roller shutter is in place, the shutter profiles begin to close from bottom to top. This provides privacy in the lower area while allowing light and / or air to enter the upper area.

[0090] Finally, the invention relates to a method for lowering a roller shutter curtain according to the invention, in which the roller shutter curtain is lowered with the panel profiles open.

[0091] When lowered, the open louvre profiles can serve as sun protection, for example, while simultaneously allowing light and air to pass through the slats and providing visibility.

[0092] According to one embodiment, the shutter profiles are closed from bottom to top when the roller shutter has reached its lower limit stop. All shutter profiles can be closed in this way as needed.

[0093] All embodiments and components of the device described here are preferably designed to be operated according to the method described here, e.g. by means of a control device.

[0094] The invention is described below by way of example with reference to the drawings. Fig. 1 a sectional view of an embodiment of a roller shutter curtain according to the invention with open panel profiles, Fig. 2 the roller shutter curtain according to Fig. 1with closed panel profiles, Fig. 3 a sectional view of a support profile of the roller shutter curtain according to Fig. 1 , Fig. 4 a sectional view of a panel profile of the roller shutter according to Fig. 1 , Fig. 5 a sectional view of an embodiment of a roller shutter curtain according to the invention with an open panel profile, Fig. 6 a sectional view of a further embodiment of a roller shutter curtain according to the invention with an open panel profile, and Figs. 7 to 11 sectional views of an embodiment of a roller shutter curtain according to the invention in different positions.

[0095] First, it should be noted that the illustrated embodiments are purely exemplary. Individual features can be implemented not only in the combination shown, but also individually or in other technically feasible combinations. For example, the features of one embodiment can be combined with features of another embodiment in any way. The roller shutter can be designed for a left-hand roller. The number of slats is essentially arbitrary and depends on the size of the window or door. Furthermore, the grooves, grilles, and recesses shown are purely optional.

[0096] If a figure contains a reference symbol that is not explained in the immediately corresponding description, reference is made to the corresponding preceding or following explanations in the figure description. Thus, the same reference symbols are used for identical or comparable components in the figures and these are not explained again.

[0097] Fig. 1 shows a roller shutter curtain with several support profiles 10, 10', 10" as well as several raised, i.e. open, panel profiles 12, 12', 12".

[0098] A first panel profile 12' is pivotally connected to a first support profile 10 via a first hinge 14.

[0099] The first hinge 14 has a first panel hook 16 of the first panel profile 12' that is curved in the direction of the panel profile front side.

[0100] The first panel hook 16 is curved clockwise in this sectional view.

[0101] Furthermore, the first hinge 14 comprises a first support hook 18 of the first support profile 10.

[0102] The first support hook 18 is curved in the same direction as the first panel hook 16, i.e. also clockwise in this sectional view.

[0103] The first panel hook 16 and the first support hook 18 interlock. Preferably, the first panel hook 16 rests on the first support hook 18.

[0104] For example, the first support hook 18 surrounds an outer side of the first panel hook 16 in sections.

[0105] The first hinge 14 can optionally have a stop 20 of the first support profile 10 arranged on the back of the support profile in order to limit the pivoting movement of the first panel profile 12' relative to the first support profile 10.

[0106] This prevents the support profile 10 from tilting backwards.

[0107] For example, the stop 20 surrounds an outer side of the first panel hook 16 in sections.

[0108] The first panel profile 12' is pivotally connected to a second support profile 10' via a second hinge 22.

[0109] The second hinge 22 has a second panel hook 24 of the first panel profile 12' curved in the direction of the panel profile rear side.

[0110] The second panel hook 24 is curved counterclockwise in this sectional view.

[0111] Furthermore, the second hinge 22 comprises a second support hook 26 of the second support profile 10'.

[0112] The second support hook 26 is curved in the same direction as the second panel hook 24, i.e. also counterclockwise in this sectional view.

[0113] The second panel hook 24 and the second support hook 26 interlock. Preferably, the second support hook 26 rests on the second panel hook 24.

[0114] For example, the second panel hook 24 surrounds an outer side of the second support hook 26 in sections.

[0115] The second hinge 22 can optionally have a stop 28 of the first panel profile 12' arranged on the rear side of the panel profile in order to limit the pivoting movement of the first panel profile 12' relative to the second support profile 10'.

[0116] This prevents excessive tilting of the 12' aperture profile forwards or upwards.

[0117] For example, the stop 28 surrounds an outer side of the second carrier hook 26 in sections.

[0118] In the case of flared panel profiles 12, 12', 12", the first hinge 14 and the second hinge 22 are only slightly offset from one another in the horizontal direction.

[0119] However, if the panel profiles are 12, 12', 12", as in Fig. 2 As shown, if the frame is closed, the distance increases horizontally. However, the distance decreases vertically.

[0120] Fig. 3 Shows a 10, 10', 10" support profile with an optional 30 mm cutout. This allows for a clear view to the outside and indirect daylight. Furthermore, air can be exchanged.

[0121] Two grooves 32 oriented parallel to one another can be provided on the rear side of the support profile, which can form part of a slotted guide.

[0122] In Fig. 4 a panel profile 12, 12', 12" is shown.

[0123] In the Fig. 5 and Fig. 6 A support profile 10, 10', 10" is connected to a panel profile 12, 12', 12".

[0124] As in Fig. 6As can be seen, a grid 34 can be inserted into the grooves 32. The grid 34 can prevent, for example, insects from entering the interior through the recess 30.

[0125] The Fig. 7 to Fig. 11 show different positions of the roller shutter curtain.

[0126] In Fig. 7 the roller shutter curtain is wound up, i.e. the window is open and is not covered by the roller shutter curtain.

[0127] Fig. 8 shows a half-open position. The window is half-covered.

[0128] The cover profiles 12, 12', 12" are already open when shutting down.

[0129] Even if the roller shutter is completely lowered, as shown in Fig. 9 As shown, all panel profiles 12, 12', 12" must be open.

[0130] Alternatively, the panel profiles 12, 12', 12" can be used in this position, as in Figs. 10 and 11shown, may be partially or completely closed.

[0131] The closing of the cover profiles 12, 12', 12" takes place from bottom to top.

[0132] In an upper and a lower area of the roller shutter curtain, one or more, e.g. two or three, slats 36 without adjustable cover profiles can be provided.

[0133] The roller shutter can therefore be used, for example, as sun protection, while at the same time providing a comparatively high level of stability.

[0134] In contrast to a previous roller shutter with similar functionality, the roller shutter according to the invention can be lowered even with the 12, 12', 12" cover profiles extended. In this way, the sun protection function can be used in any position of the roller shutter.

[0135] This maintains a clear view to the outside, and the indirect daylighting of the building is high. This saves energy required for artificial lighting and / or air conditioning.

[0136] With closed panel profiles 12, 12', 12" the roller shutter offers high weather resistance and thermal insulation, which can save heating energy in colder seasons. List of reference symbols
