Description

[0001] Profile cover assembly

[0002] The invention relates to a mounting device for attaching a cover to a profile rail according to the preamble of claim 1, as well as a corresponding method for attaching such a cover with a deformation aid.

[0003] Specifically, the invention relates to a roller specifically designed for mounting a translucent plastic cover - for example as a diffuser or as a light-guiding film - on a U-shaped lighting profile rail, in which rail illuminants such as LED strips or the like are housed or attached.

[0004] Generic lighting profiles or light rails within the meaning of the present invention are shown, for example, in WO2023 / 012507 or WO2023 / 012744. These consist of a rigid profile rail, e.g., made of metal or plastic, with a generally U-shaped or H-shaped cross-section, fitted with lamps inside. For aesthetic reasons, to protect against dirt or contact, and / or for lighting-related reasons, such lighting profiles are often provided with a cover. This cover is typically supplied as a long, straight plastic rod with the profile rail and is attached to the profile by hand after the lighting has been installed.

[0005] Handling and installing the covers is often challenging, as they consist of long, thin strips that are difficult to handle. Due to their geometry alone, the covers are often so flexible that they bend or sag during carrying, transport, and installation, or they can even break.

[0006] Attaching the cover to such lighting can be particularly difficult, as such lighting profiles are often mounted on ceilings or suspended freely, e.g., on cables.

[0007] Another difficulty is the transport-related maximum length of the cover strips of 2 m, 4 m, or 5 m – depending on the manufacturer and method of transport. This often results in joints in the cover, which are not only unsightly but also difficult to install with a clean, seamless connection. The translucent covers must also be kept clean to ensure a visually appealing appearance. This means that dirt, dust, or fingerprints should not stick to them, which is why installation should preferably be carried out with clean gloves, which increases the installation effort.

[0008] The known solutions are disadvantageous in one way or another, particularly with regard to the handling of consumables, their transport, ease of use, high levels of waste, difficulties during the assembly process, numerous joints, etc., which increases the material expenditure and the amount of waste. The object of the present invention is therefore to create a device and provide a method which does not have or minimizes the aforementioned disadvantages. In particular, an improved assembly for a profile rail cover is to be provided which leads to less waste and consistently allows for a high level of workmanship. In particular, an assembly method is to be developed which is simple and reliable to use. For this purpose, a corresponding assembly device can be provided which implements this method or facilitates its implementation.In addition to simplifying assembly, specific tasks include avoiding / reducing joints, avoiding / reducing finger contact with the cover, avoiding / reducing offcuts and waste, reusability of leftovers, reliable installation even in difficult, confined installation locations, etc.

[0009] The objects are achieved by the features of the independent claims. Advantageous developments and embodiments are set forth in the figures and in the dependent claims, as well as in the following description.

[0010] According to the invention, a profile cover mounting device is provided, which is designed for attaching a cover to a profile rail. This profile cover mounting device is also referred to below as a mounting device or roller.

[0011] In completely different technological contexts, the term "roller" is typically used for window seals that are pressed into grooves on windows. This is clearly not what is meant in this document. Also clearly not meant is a device for inserting LED strips, such as the "Roller for LED Stripes / 8mm" from kmd Industrievertretungen (www.km-decor.ch / de / produkt / einroller-fuer-led-stripes-8mm / - accessed on February 27, 2024). Therefore, the term is now being used for a new purpose and a new device.

[0012] A preferred embodiment of the invention or of the roller is designed, for example, for mounting a translucent or light-directing plastic cover on a U-shaped lighting profile rail, for example, an aluminum or plastic profile, which initially has a continuous open area along its length for light emission, which is to be closed with a cover in the form of a translucent, especially transparent, translucent, frosted glass-like plastic cover. In addition to physically sealing the profile against dust or contact, the plastic also acts in particular as an optical diffuser or light-directing unit for the light emission.

[0013] Such profile rails can have special dimensions of, for example, around 1 to 12 cm wide in cross-section and are as long as the lighting is required - usually in ranges from over one meter up to several tens of meters, whereby the profile rail can also be cut to lengths to facilitate / enable transport. For example, typical profile rails for such applications are roughly U-shaped in cross-section, or describe a rectangle or square in cross-section with one (at least partially) open side, with dimensions of, for example, 20 mm by 20 mm or 50 mm by 40 mm. In other embodiments, the profile rails can also be roughly H-shaped in cross-section, with two side walls and a central web as well as two (at least partially) open surfaces, e.g. an open front (to be covered) for the light output and an open back for mounting and / or for the power connection.In particular, these profile rails can also be formed with grooves and / or webs in cross-section. The term longitudinal grooves here includes not only an elongated depression of any shape, but also a channel formed between two raised longitudinal webs. For example, the profile rail can be formed with at least one lateral longitudinal groove in each of the raised longitudinal webs. In particular, the profile rail can be formed with longitudinal grooves or longitudinal webs in the area of ​​or on the light exit opening of the lighting profile, which are specially designed to receive the cover on both sides in a form-fitting manner. Preferably in such a way that the cover ends or closes almost or substantially flush with the opening in the profile rail. In other embodiments not currently claimed, the cover can also be force-fitting orbe attached to the profile rail with frictional engagement, in particular by elastically clamping the cover and / or the profile rail.

[0014] The cover can be an elastically bendable, specially rollable, translucent plastic strip, for example with an approximately rectangular cross-section and a width designed such that the cover can be positively received in the profile rail, especially in a cover holding formation such as longitudinal grooves or between longitudinal webs. The height of the cross-section does not necessarily have to be constant across the width and should be selected so that sufficient light transmittance, diffusion and / or a special light emission effect is achieved, for example in the range of 0.1 mm to 0.8 mm, especially about 0.15 to 0.3 mm. The length of the cover or cover strip is many meters, for example from approx. 10 to 40 meters, especially e.g. 20 meters per roll.The cover according to the invention can also be provided on large rolls with a length much greater than this and from there rewound onto the rolls of the reel according to the invention.

[0015] The profile cover mounting device according to the invention, or the new roller, comprises an outer housing. This housing is preferably made of plastic, a sustainable material such as bamboo, cardboard, paperboard, and / or metal and serves to hold and handle the mounting device, specifically for accommodating a roll or spool for a quasi-endless cover. It can therefore have an approximately cylindrical recess for such a roll and preferably a mounting option for the roll that can be rotated around its center. The diameter of the roll should be in the range of approximately 10 cm to 40 cm. The width of the roll or of the profile cover mounting device is accordingly somewhat wider than the width of the cover.

[0016] The cover to be installed can be wound or wound onto such a roll, which is a replaceable part of the profile cover mounting device according to the invention. The roll is inserted or wound into the outer housing. To perform the cover assembly, the roll must be inserted into the outer housing and the cover wound onto the roll. These elements can also be separated during delivery, sale, storage, etc., to form a profile cover mounting device according to the invention.

[0017] The outer housing forms at least one rail guide, with which the outer housing can be positioned against the profile rail in a defined position and moved along its longitudinal direction. The profile cover mounting device can thus be guided in or on the profile and moved along the profile. For example, it can be moved glidingly along the open side of the profile rail, with the rail guide and profile rail providing lateral guidance in a defined position relative to each other.

[0018] The rail guide is preferably also designed such that it can be clipped into the profile rail. For example, the rail guide can have recesses that engage in the lateral grooves or guides into which the cover is then mounted. The roller can thus be designed such that, when clipped in, it holds onto the profile rail, especially orthogonal to the plane of the cover. This can make overhead work or similar easier, for example, because the roller itself holds onto the profile and cannot fall down, even if it is released. In other words, the outer housing should, in a special embodiment, also be designed such that it holds itself in the profile in an overhead application, while, for example, the assembly platform on which the fitter stands while working on the ceiling can be moved or relocated, which is often the case with long lighting lengths.

[0019] In a primary embodiment, the invention thus relates to a profile cover mounting device for attaching a cover to a profile rail, specifically for mounting a preferably translucent plastic cover in lateral longitudinal grooves on a U-shaped lighting profile rail. This mounting device comprises at least one outer housing—for example, made of plastic or metal or of a sustainable material such as bamboo, cardboard, or paperboard—and a roller onto which the cover can be wound or is wound for provision, and which roller can be inserted or is inserted into the outer housing in a rotatable manner. The outer housing is designed with at least one rail guide, with which the outer housing can be placed on the profile rail in a defined position or can be clipped onto its longitudinal grooves and displaced in its longitudinal direction.According to the invention, the rail guide is designed in this embodiment such that the cover:.

[0020] - in a first position A along the longitudinal direction, in particular only, on a first side of the profile rail in its first longitudinal groove and

[0021] - in a second position B along the longitudinal direction on a second side of the profile rail into its second longitudinal groove.

[0022] The first and second positions A, B are spaced apart from each other in the longitudinal direction by a distance greater than 0 mm and 0 mm, respectively, in particular by more than 10 mm, for example, 30 mm to 50 mm. Preferably, the first and second positions in the direction of movement during insertion can be considered a sequence.

[0023] In a similar way, using the principle or device / method of the invention, an already installed cover can also be rolled out of a profile rail—i.e., disassembled. The cover can then be advantageously rewound onto the roll, preventing it from becoming dirty or damaged, for example. After the LEDs have been successfully repaired / replaced, the same cover can be reapplied using the roller.

[0024] Preferably, in position A, a lateral stop for the cover on the outer housing is formed when the rail guide is inserted, which causes a relative positioning of the cover with respect to the longitudinal groove on the first side, so that the cover comes to lie at its edge / side in the longitudinal groove.

[0025] Preferably, in the first position A, the cover is guided lower on the first side by the outer housing or its rail guide than on the second side. Height and depth refer to the position within the legs of the profile rail, for example measured on its side walls relative to the upper edges of the profile side walls at their open end. For example, in position A, the cover is guided at the height of the longitudinal groove on the first side and the height of the cover on the second side is guided outside or above the longitudinal groove or the upper edge of the profile rail. Thus, in position A, a first side of the cover is positioned or inserted in the first longitudinal groove. In the second position B, the cover is then also guided on the second side at the height of the longitudinal groove. In position B, the first side is preferably also guided at the same height of the longitudinal groove so that it remains reliably in it.This means that a second side of the cover is also positioned or inserted in the second longitudinal groove - and the cover is thus mounted. The rail guide preferably has a counter-holder below the cover, which is arranged such that the cover is guided between the outer housing and the counter-holder in a defined position, in particular height. The counter-holder is arranged - with the profile cover mounting device applied or attached to the profile rail - so that it lies in the profile rail at the lower edge or slightly below the height of the longitudinal groove. As described above, this height positioning is achieved by the counter-holder in the longitudinal grooves, specifically on the two profile or cover sides at two different positions A and B in the longitudinal direction, for example by providing lateral outlets for the cover on the rail guide, each in different longitudinal positions.This allows the cover to be inserted correctly into the longitudinal groove and cannot fall too deeply into the profile rail.

[0026] Preferably, the outer housing is formed with a recess / nose in the area of ​​or at the end of the cover insertion, which positions the cover at the height of the longitudinal grooves on the first and second profile rail sides. The cover is preferably additionally supported by the counterholder on the opposite side, so that the cover does not lie or guide too deeply into the profile rail (e.g., below the longitudinal groove).

[0027] Preferably, the outer housing can be formed in the region of positions A and B with a counter-holder, which is designed and arranged such that the cover can be guided between the rail guide and the counter-holder, in particular wherein the outer housing forms additional lateral guide elements for the lateral positioning of the cover in the outer housing, which are shaped to insert the cover at the respective position A, B into the respective longitudinal groove or to hold it therein.

[0028] The rail guide preferably has at least one, preferably several, clip-in formations, which are designed to clip into the lateral longitudinal grooves in the profile rail when attached to the profile rail. This can be done in particular in such a way that the mounting device automatically holds itself to the profile rail. For example, these clip-in formations can be designed in the form of elastically movable / deformable hooks or locking lugs on the counterholder located within the profile rail. For example, in the form of at least four hook lugs.

[0029] Preferably, the roller can be inserted or inserted into the outer housing in an interchangeable, rotatable manner.

[0030] Preferably, the reel or outer casing can be provided with a range indicator, which is particularly provided with a scale of values ​​for the remaining cover length on the reel. Preferably, this scale of the remaining length increases non-linearly from the outside to the inside, or, in the case of a mechanical brake on the reel, the scale increases from the inside to the outside. A braking device, particularly a mechanical one, for the reel can preferably be provided on the reel and / or on the outer casing. Specifically, this braking device prevents unwinding due to the "spring force" of the cover. By preventing unwinding by a brake or other suitable means, the remaining length indicator can be made clearly readable in any situation.

[0031] Preferably, the rail guide can be designed with at least two transverse webs or clip or holding devices arranged at a distance in the longitudinal direction of the profile in the direction of the profile width, which are shaped in such a way that they can each be placed laterally on an upper edge of the profile rail and protrude into the profile interior between them and / or rest on a partial area of ​​the sides of the profile rail outside the profile width.

[0032] The profile cover mounting device is preferably designed with a separating or cutting device or a cutting aid for the cover. For example, in the form of a blade or a guide for a blade of an external cutter or knife. Using this cutting device or cutting aid, the cover can be cut, severed, scored, or marked. This is done specifically at a defined position in the longitudinal direction, which is adapted, in particular, by a stop on the rail guide to a length of the profile rail or an end cap of the profile rail, preferably with a defined separation or cutting at a defined angle to the profile rail, for example, at 90 or 45 degrees.

[0033] In other words, an embodiment of a cover roller according to the invention can be characterized by at least one of the following aspects. The cover is wound on a roll and can be rolled directly into the profile. The contour on the underside of the cover roller is designed so that the cover can be applied directly into the profile. Because the cover is applied asymmetrically into the groove of the LED profile, smaller forces are generated than with the cambering described above. Asymmetric application means: First, the cover is pushed in on the rear side (in position A). Then the cover is pushed or pressed in on the front side (position B). The cover is supported on the underside of the roller so that there is no possibility of the cover falling through the groove into the profile. The entire roller is clipped into the profile using, for example, four clips. This enables guided rolling in.It is also possible to release the roller. This is an advantage when working on longer lengths where it is not always possible to roll the cover up underneath in one go. For example, on a ladder, especially if the ladder has to be moved while it is being rolled up. In a further embodiment, the cover can be cut straight and in the correct position using a cutting aid. The housing of the cover roller has a continuous cutting aid which guides the cutter blade and thus guarantees a straight cut of the cover. A stop can advantageously be formed on the underside of the roller, which serves to determine the end of the cover. This allows the cover to be reliably cut to length contiguously and / or parallel to the end cap. End product: profile with concluding, straight cover to end cap.

[0034] The outer housing further forms at least one insertion lug, which is shaped and arranged in such a way that – when the cover is mounted using the mounting device according to the invention – this insertion lug causes such positioning and elastic deformation of the cover. This allows the cover to be inserted into the profile rail in an area near the insertion lug. After the elastic deformation caused by the insertion lug has been relieved, the cover remains in the profile rail.

[0035] Preferably, the profile cover mounting device is designed in such a way that when it is pressed against the profile rail and moved along the profile rail, the deformed cover can be inserted in the area of ​​the insertion lug into cover holding recesses - for example in longitudinal grooves or between longitudinal webs on the profile rail - and when the elastic deformation returns outside a length range around the insertion lug which causes the deformation, the cover is positively inserted into these cover holding recesses or engages and remains positively locked in place. This allows simple and securely positioned insertion of the cover into the cover holding recesses of the profile rail by simply pulling the mounting device along the profile rail. Preferably, the cover is not clamped into the profile with force after insertion, but lies positively - for example.a perfect fit or slightly loose in the longitudinal grooves of the profile rail.

[0036] The insertion lug is preferably shaped and arranged in such a way that it causes an elastic crowning or bending of a cross-sectional area of ​​the cover. In particular, the insertion lug can form a curve that protrudes downwards into the space in the direction of the profile rail, in particular a convex curve. This allows the cover to be deformed in a defined manner so that it can be inserted optimally. In another embodiment, an inwardly recessed curve can also be formed on the insertion lug, in particular a concave curve. Advantageous geometric shapes of the insertion lug can be specifically adapted and optimized for the cover and profile rail used, for example through calculations, simulations and / or tests.

[0037] Preferably, the lowest point of the insertion lug is lower than an upper support surface of the rail guide, which is designed to rest on an upper edge of the profile rail. Thus, when the assembly tool is applied to the profile rail, the insertion lug protrudes at least partially into the interior of the profile, whereby the cover is also elastically deformed in this direction. This allows the cover to be inserted into the profile in a controlled and positioned manner by simply rolling it in using the roller. In another embodiment, the deformation could also occur in the other direction, which is analogously possible according to the invention. However, this may require more technical effort in the design of the assembly tool, particularly the design of the insertion lug, guides, holders, counterholders, etc.

[0038] Preferably, the outer housing forms a handling feature, such as a finger rest, a push handle, or similar. This allows the mounting device or the insertion lug to be pressed against the profile rail, making it easy to operate by hand. In particular, the handling feature is designed and arranged to apply a contact force with which the insertion lug and / or rail guide can be pressed against the profile rail—specifically, a contact force sufficiently large to cause the elastic deformation of the cover. The profile cover mounting device should also fit comfortably in the hand. Versions for right- and left-handed users can be specially offered.In another embodiment, however, a roller according to the invention can also be mechanically applied to a profile and guided along it, wherein a machine applies the contact force and carries out the guiding along, whereby the handling shaping is essentially replaced by a machine assembly shaping.

[0039] The profile cover mounting device is preferably shaped and configured such that the cover emerging from the profile cover mounting device at the insertion lug rests laterally on at least one, preferably two, edges of the profile rail or longitudinal webs during its installation. Thus, a counterforce to the contact force exerted by the profile rail on the cover is exerted at this edge or these edges, which causes the elastic deformation of the cover. In particular, the contact force acts via the insertion lug essentially centrally in the direction of the profile rail on the cover cross-section. Counterforces from the profile rail edges act laterally on the cover cross-section in the direction of the roller. This causes the cover cross-section to bend elastically in the center. The resulting bending radius reduces the overall width of the cover, which makes insertion into the profile easier or possible.

[0040] In particular, according to the invention, the cover, in a flat, stress-free state, has a cross-sectional width as wide as the inner width of the profile rail in a stress-free state. Specifically, it is approximately or exactly as wide as the interior of the cover retaining recesses into which the cover is inserted. Thus, it has a width roughly corresponding to the depth of the longitudinal grooves or the width between the longitudinal webs on the profile rail into which the cover is to be inserted. This enables the installed cover to be securely held in the profile rail.

[0041] The outer housing of the roller is preferably formed with a counterholder in the area of ​​the insertion lug. This is designed and arranged such that an inserted cover can be passed between the insertion lug and the counterholder. This allows the cover to be additionally or more precisely defined in its position. Additionally or alternatively, the counterholder in conjunction with the insertion lug can also cause an at least partial elastic deformation of the cover, so that its insertion is facilitated and / or the contact force can be reduced. Furthermore, the outer housing can additionally form at least one lateral guide element for the lateral positioning of the cover in the outer housing. This allows the lateral position of the cover relative to that of the profile rail or rail guide to be more precisely defined.For example, one side of the outer housing can be closed in the area between the unwinding of the cover from the roll and the insertion nose, and the opposite side can form a slot for inserting the cover, which slot is designed with the counterholder and / or at least one guide element.

[0042] The roll is preferably provided with at least one range indicator. This can in particular be provided with a scale of values ​​​​depicting the cover length still present on the roll. This remaining length scale of the cover preferably increases non-linearly from the outside to the inside, thus taking into account both the spiral shape and the tendency for the cover to unwind elastically on the roll when forming the scale. Preferably, a device is provided which ensures that the roll always remains wound up. For example, unwinding of the cover on the roll, which tends to occur due to the spring force of the rolled-up cover, can be prevented or reduced by securing the inserted roll with a mechanical brake or inhibiting its rotation.This ensures that the roll always remains wound up, and the remaining length scale is always clearly legible, which would not always be possible if the cover was partially unwound from the roll. This allows the installer to avoid splitting the cover, as it is always clear whether the cover on the roll is still sufficient for the current profile length. Otherwise, the roll can be replaced as a precaution. The roll with the currently too short remaining cover can then be reused later on a shorter profile rail. This avoids both waste and joints in the installed cover.

[0043] The rail guide is preferably designed with at least two transverse webs arranged at a distance from one another in the longitudinal direction of the profile in the direction of the profile width. These cross webs can, for example, be shaped such that they can each be placed laterally on an upper edge of the profile rail and partially protrude into the interior of the profile between them. Instead of or in addition to an inner lateral guide by protruding, the rail guide can also rest on a partial area of ​​the sides of the profile rail outside the profile width. This can ensure secure guidance or manual guidance of the roller and, in particular, prevent tilting due to offset or skewing. In particular, the rail guide can have clip-in formations designed to clip into the cover holding formations or lateral longitudinal grooves - especially those into which the cover is then inserted.This clipping is preferably carried out in such a way that the mounting device automatically holds itself to the profile rail.

[0044] Preferably, the roll can be inserted or inserted into the outer housing in an interchangeable manner. This makes the roller reusable. The rolls can also be optionally refilled or rewound from a large roll, which advantageously takes place while not in use. The roll can be specially designed to have a minimum inner radius, which is designed such that the cover used does not experience irreversible plastic deformation at this minimum radius. It is thus preferably curved only within the elastic range.

[0045] Preferably, the cover is unwound from the roll in the profile cover assembly device in such a way that the cover is guided at least approximately parallel to the profile rail during unwinding. Specifically, unwinding takes place in an area where the roll is closest to the profile rail, and from there, the cover is guided approximately parallel to the profile rail or slightly diagonally to it. This allows the cover to be advantageously fed onto the profile rail and initially relaxes the tension on the roll winding before the profile is inserted. Furthermore, such a flat guide in this area facilitates defined positioning of the cover using guide elements, guiding elements, and counterholders.

[0046] Preferably, in one embodiment, the roller is equipped with a separating or cutting device for the cover. With this, the cover can be cut, severed, scored, or marked. The roller with such an optional separating or cutting device can further simplify cover assembly. This can avoid the need for an additional tool. This separating or cutting device can preferably be formed in the area of ​​the insertion nose so that separation can take place directly during rolling and, in particular, the separation position can be easily adjusted to the profile length. In addition, this also makes it possible to always produce a clean cut - even at an angle, which can be difficult to do by hand with scissors or the like.Alternatively or additionally, a marking aid can also be provided on the roller, with which a cutting mark for cutting to length can be created on the cover - for example a line with a defined position and / or orientation, at which the cover can then be cut more easily - for example by hand with an external cutting tool.

[0047] In an analogous manner, the invention also relates to a method for mounting a cover on a profile rail, in particular a light cover on a lighting profile, with a deformation aid.

[0048] The process is characterized by its process steps and activities and is not necessarily tied to a specific hardware for it - however, it can be carried out, for example, with a profile cover mounting device or a roller, the design of which is also described here, and its design details.

[0049] In a first embodiment, the invention relates to a method for mounting a cover on a profile rail, such as a light cover on a lighting profile, which is carried out using an insertion aid. For example, a corresponding profile cover mounting device as mentioned above can be used, or another insertion aid designed to carry out the method steps according to the invention. The method provides for rolling the cover into lateral cover retaining recesses or longitudinal grooves of the profile rail, with

[0050] - guiding the cover at a first position A in the longitudinal direction of the profile rail, so that the cover is inserted into a first longitudinal groove provided for the cover on a first side of the profile rail. Specifically, this can be achieved by guiding it at the height of the first longitudinal groove. In this position A, on an opposite second side of the profile rail, the cover is outside, specifically above, a second longitudinal groove.

[0051] - guiding the cover at a second position B, spaced longitudinally from the first position A, so that the cover is inserted there on the second side of the profile rail into a second longitudinal groove provided for the cover, opposite the first. Specifically, this can be achieved by guiding it at a height of the second longitudinal groove at this position B. In this position B, the cover is also guided on the first side at the height of the first longitudinal groove of the profile rail.

[0052] In particular, the guiding can be carried out as geometric or mechanical guiding, for example by means of a mechanical stop guide of the cover in the insertion aid.

[0053] - sliding of the insertion aid along the profile rail, during which the cover inserted is unrolled from a roller.

[0054] In another embodiment, the method comprises rolling the cover into lateral cover holding formations or longitudinal grooves of the profile rail and is carried out by pressing the cover onto the profile rail by means of an insertion nose which is designed and shaped in such a way that an elastic deformation and positioning of the cover by an insertion nose takes place in such a way that an outer width of a cross-sectional area of ​​the cover is reduced by the elastic deformation in such a way that it can be introduced between the cover holding formations and a positioning between them takes place, as well as with a sliding of the pressed insertion nose along the profile rail, during which the introduced cover rolls off a roll.Due to the elasticity of the cover, the elastic deformation of the cover is reversed in an area outside the insertion nose, so that the cover remains positively locked in the cover holding formations.

[0055] Optionally, the cover can also be removed from the profile rail by moving it in the opposite direction to the rolling movement, thereby rolling the cover out of the profile rail in the opposite direction.

[0056] The invention equally relates to embodiments that include not only the profile cover mounting device or the roller itself—i.e., the outer housing and roller assembled or provided separately for this purpose—but also a cover mounting set consisting of at least one profile cover mounting device and at least one cover. In this set, the cover can preferably be wound on one or more rollers, but can also be provided simply for winding.

[0057] The invention also relates to a lighting rail set comprising at least one cover mounting set as described above and at least one profile rail. For example, a lighting profile rail with a light source that can be or has been inserted therein, in particular at least one LED strip, LED strip, or LED module.

[0058] Alternatively, a roller according to the invention or the method can also be used in an analogous manner with non-transparent covers for electrical installations, for example in cable ducts or the like.

[0070] Fig. 8 is a third partial view of the roller from Fig. 5 and subsequently viewed from the side of the profile rail.

[0071] Fig. 1 shows an example of an inventive assembly of a cover 40 of a profile rail 50 using a deformation aid. In the embodiment shown, the roller 30 designed according to the invention is used as the assembly device. This assembly device 30 is placed on the profile rail 50 and pressed against it. For example, the assembly device 30 can be designed with a finger rest 33 or a pressure handle or the like, which facilitates holding or pressing against the profile 50 without hindering rotation of the roll 31. The cover 40 is provided or dispensed from the roll 31 on which it has previously been wound. Advantageously, the roll 31 can be designed to be interchangeable, for example, to accommodate different cover variants (e.g., with different optical properties, colors, surfaces, shapes, etc.).) and / or to be able to select a roll on which a sufficient length of cover is available, so that it preferably covers the entire profile length. For example, a previously partially used leftover roll 31 can be used, with a remaining cover length that is sufficient / suitable for the current profile.

[0072] There may be designs in which the rolls 31 are provided / supplied with the cover 40 wound thereon, or in which the rolls 31 are refillable by the user, e.g., by transferring or rewinding the cover from a large roll onto the roll 31 of the roller 30. Alternatively, in another embodiment—e.g., for single-use applications—the rolls 31 with the cover may also be a non-replaceable part of the roller 30.

[0073] In order to know or make visible the remaining length of the cover 40 on a roll 31, the roll 31 and / or the housing 32 of the roller 30 can be designed with a range indicator 38 or a fill level indicator, which is designed to make it recognizable, estimable or measurable how much length of cover 40 is currently on the roll 31. The range indicator 38 is preferably designed with a length scale, from which it can be read how many running meters of cover are still available on the roll 31. The scale can preferably assume higher values ​​in the roll diameter from the outside to the inside, so that the cover under tension can develop from the roll center and adapts to the outer roll radius, thus allowing a reliable reading of the remaining length. In particular, the scale is adapted non-linearly over the radius in order to take into account the spiral winding of the cover length.

[0074] The cover 40 is unwound from the roll 31 in the region of its profile support in the rolling-in device 30 in order to be mounted on the profile rail 50. According to the invention, the cover 40—optionally additionally or alternatively also the profile rail 50—is elastically shaped / deformed and positioned by the rolling-in device 30 such that the cover is attached / installed in the profile. Specifically, the cover is then held by a positive fit; for example, by inserting the cover 40 into designated retaining recesses, such as longitudinal grooves 51 of the profile rail 50 or longitudinal webs. Examples and details of such a deformation of the cover will be explained further in the following detailed views.

[0075] To install the cover, simply place the roller 30, with the cover 40 on its roller 31, onto the profile rail 50, or press or clip it into place. Initially, the cover should protrude at least slightly from the roller 30. While pressing, the roller 30 is moved or pulled—e.g., sliding—in the installation or movement direction 70, whereby the cover 40 is inserted into the profile 50. "Luxxit" is a trademark of the applicant. In the figures, this designation has no meaning, except that the devices shown are identified by this trademark.

[0076] Fig. 2a shows an overview of a roller 30 according to the invention during the attachment of the cover 40 to the profile rail 50. Specifically, a roll 31 with a cover 40 wound thereon (preferably with sufficient length for the entire profile length) is inserted into the roller 30, for example, clipped in place in a replaceable manner at the center of rotation of the roll, as shown. The cover 40 is mounted on the profile rail 50 in the area of ​​the marked circle 73 by means of the roller 30. To make this clearer, the profile rail 40 is shown in the illustration with a partial recess 71 on the side in this area - which is possible in practice, e.g., for branches, feeds, special geometric boundary conditions, etc. - but as a rule, the profile rail 40 will be continuous on both sides, without such a physical recess 71.

[0077] Fig. 2b shows the detailed view 73 marked with a circle in Fig. 2a, again enlarged. For easier recognition, the cover 40 is shown here with a pattern and - as mentioned - the profile 50 is shown graphically with a recess 71, so that the rolling-in process is more clearly visible. In the assembly device 30, the cover 40 is unwound from the roll 31 in the area of ​​the profile 50 and brought into the assembly position relative to the profile 50 with guide elements 34 and / or shaped elements 36 while the profile 50 unrolls.

[0078] Specifically, in the example shown, a cover 40 with a substantially rectangular cross-section is introduced into the profile 50. However, the invention is not necessarily limited to such a rectangular cross-sectional shape. For example, the cover 40 can also have longitudinal grooves or longitudinal webs and, for example, form a flat U-profile, the side surfaces of which are designed to be held inside or outside on the profile side walls of the profile 50, for example with appropriately designed shapes for a positive fit or under elastic tension of the material under frictional fit. The cover is at least partially translucent for lighting, preferably transparent or translucent, acting, for example, as a diffuser or light guide. Light from a lighting element 52 (not shown here) attached to the profile 50, for example via the lighting unit attachment 53, can thus be advantageously emitted.the lighting unit 52 must also be physically and / or mechanically protected.

[0079] In lighting applications, the profile rail 50 is usually an opaque lighting profile, usually made of metal or plastic, for example an extruded aluminum profile, which is essentially U-shaped. The profile width 54 and profile height 55 are usually in the range of approximately 8 mm to a few (e.g. up to 10) cm, especially in the range of 1 to 5 cm. These cross-sectional dimensions are usually considerably smaller than the profile length 56, which is usually well over 10 cm, usually a few tens of centimeters to several meters. The profile rail 50 is usually designed with a cross-sectional shape which forms holding structures, in particular longitudinal grooves 51 or longitudinal webs 51 along the longitudinal extent 56, which are designed to receive lighting elements and / or the cover 40 and hold them in a form-fitting manner in or on the profile 50.

[0080] With the insertion nose 36 shown, the cover 40 is deformed in the elastic range of the material of the cover 40, for example bent or cambered, and brought into the assembly position, in this example below the upper edge of the profile 50. Furthermore, a guide element 34 can be formed below the cover 40 on the roller 30 in order to further define the position and / or shape of the cover 40.

[0081] Fig. 3 again shows the pressing 72 of the roller 30 with a force and the movement 70 of the roller 30 along the profile 50. For this purpose, a rail guide 35 is advantageously formed on the roller 30, by means of which the roller 30 rests against the profile 50 and is guided relative to it. For example, the shape of the rail guide 35 can slide inside 57 or outside the profile 50 and be supported in a defined position relative to the profile 50 and / or extend over a certain length to also define the angular orientation.

[0082] The roller 30 can be designed in the area of ​​the profile rail 50, especially at the rail guide 35 and / or at the insertion lug 36, with a clip device or a locking formation, with which the roller 30 is held independently in the profile rail 50. This locking formation is particularly designed such that, when the roller 30 is pressed, it engages in the longitudinal grooves or cover holding formations 51 (51a and 51b), thus preventing the roller 30 from being lifted off the profile rail 50, or only being able to do so in the opposite direction with the application of external force. In the figures, this is shown concealed by the profile rail.

[0083] Due to the shape of the insertion nose 36 and the guide elements 34, 34b, and particularly under the influence of the force 72, an elastic deformation 41 is caused in the cover 40 in the longitudinal insertion area—which is shown here by the graphical recess 71—specifically a crowning or bending of the cover. This reduces the width of the curved cover 40, allowing it to be easily inserted into the longitudinal grooves 51 of the profile rail 50. Due to its elasticity, the cover 40 returns to its original shape after the insertion area, where it remains in the longitudinal grooves 51.

[0084] Alternatively or additionally, especially with profile rails 50 made of sufficiently elastic material, the roller 30 can also elastically expand the area of ​​the profile rail 50 into which the cover 40 is inserted in the area of ​​the insertion 71 to facilitate or enable insertion. This can be achieved, for example, with a correspondingly widening geometric design of the rail guide 35 on the roller 30.

[0085] In another, not illustrated embodiment of the invention, the cover 40 can be deformed by the roller 30 in the opposite direction, with its belly pointing upwards - pointing away from the profile 50 - instead of the deformation shown with its belly pointing downwards - towards the profile interior 57. In the preferred embodiment, the cover returns to its original cross-sectional shape, for example, flat, after insertion and reversal of the elastic deformation. In special embodiments not currently claimed, at least part of the concave or convex deformation of the cover can be retained, for example by the cover remaining clamped in the profile with a force fit and unable to fully recover. For example, this can also be used to achieve different radiation behaviors of the light strip (with the same cover material).

[0086] The roller 30 can be designed specifically for a single or for several different profiles 50 and / or for a single or several different covers 40 - especially with regard to the shape of the rail guide 35, insertion nose 36 and / or guide elements 34.

[0087] The roller 30 can also roll several stacked films into a profile rail in one go. For example, with a roll containing an opal film 1 (inside) and a film 2 above the film 1, which film 2 is designed as a microprime film or light-directing film.

[0088] In one embodiment, the roller 30 according to the invention is also used as an “unroller” in that the cover 40 can be removed from the profile 50 onto an empty roller 31 in an analogous manner with the opposite movement 70.

[0089] Not shown here for clarity, the roller 30 can optionally also be provided with a separating or cutting device for the cover 50. This is preferably arranged in the area of ​​the insertion nose 36, for example with a blade, a knife, or scissors either on the roller 30 itself or on a guide device for external separating or cutting devices. Alternatively or additionally, a cutting marking device can also be provided. This allows the cover 40 to be cut, severed, scored, or marked to the same length as the profile when the end of the profile is reached.

[0090] Fig. 4 once again clearly shows the deformation 41 of the cover 40 with the roller 30 according to the invention in the exposed insertion area 71. This is specifically caused by the insertion nose 36, specifically by its shape and arrangement, which causes an elastic deformation of the cover in the insertion area. For example, the insertion nose 36 is deeper in the area of ​​the profile center than the lateral rail guides 35 or 35b, which rest on the profile 50, so that the cover 40 is deformed, specifically according to the shape of the insertion nose 36.The contact force 71 shown in the previous figure is supportive here, as it acts downwards via the insertion lug 35 in the central cross-sectional area of ​​the cover, whereas the lateral supports of the cover 40 on the profile 50, especially in the area of ​​the longitudinal grooves 51a, 51b, cause upward counterforces, so that the cover 40 bends elastically and becomes smaller in width due to the resulting bending radius, so that the cover 40 can be easily inserted or clipped into the longitudinal grooves 51a, 51b. In particular, the interaction of the insertion lug 36 with the guide element 34 as a counter-holder and / or the rail guide 35 as a positioning aid is advantageous, in particular for the advantageous definition of the deformation 41 and position of the cover 40 in the insertion area.

[0091] In an embodiment with a locking formation on the roller 30, which is designed to hold the roller°30 independently in the profile rail°50, the forces or counterforces for the deformation of the cover can also be caused or maintained entirely or partially by this locking connection.

[0092] Alternatively, the cover 40 can also be inserted in such a way that the cover 40 is attached indirectly in the profile in accordance with the invention - e.g., indirectly via a connection to an element that is attached in the profile, such as the lighting unit 52.

[0093] Another example of an embodiment of the invention is shown in Fig. 5a and below. The following description primarily addresses the most significant differences from the previously mentioned embodiment. Many of the variants or special features mentioned above can be applied or combined in the same or analogous manner in this embodiment, even if not all of them are explicitly shown and / or described. For better visibility of the procedure, a viewing window 71 is again cut out of the profile rail 50 in the drawing, which, of course, is usually not physically present in practice.

[0094] The roller 30 is placed against the profile rail 50. This is achieved by inserting / positioning the rail guide 35 into the profile rail 50 and pressing the roller 30 against it 72. This creates a defined position of the outer housing 32 relative to the profile rail 50. The roller 30 can be pressed against it throughout its entire use, but is preferably held against the profile rail 40 with holding elements 35c, as described further below, during its use, in particular in such a way that permanent pressing is not absolutely necessary. With the first pressing, the roller 30 in the area of ​​the outlet of the cover 40 can already be inserted into the longitudinal grooves 51 provided for this purpose and / or the holding elements 35c can be engaged. To roll the cover 40 from the roll 31 into the profile rail 50, the roller 30 is then moved in the direction 70 along the profile rail 50.The other referenced elements can be designed as usual.

[0095] Fig. 5b shows the rolling-in process of this embodiment in detail, wherein, for the sake of clarity, the roller 30 itself has been hidden, so that only an exemplary profile rail 50 and the cover 40 - and how this is guided by the roller 30 according to the invention - are shown. In this case - viewed in the direction of movement 70 of the roller - in the first position A, the cover 40 is first inserted into the longitudinal groove 51 of the first side 59a of the profile rail 50, while the other side of the cover 40 is still guided outside or above the profile rail 50 in this position A. This is achieved specifically in that the roller 30 has a corresponding geometric guide for the cover after the cover 40 has been unrolled from the roll 31. For example, with appropriately designed and shaped limits or stops or guide webs, the cover 40 can be guided as shown or in a similar manner.At a longitudinal distance d from position A, the cover 40 is then subsequently inserted into the longitudinal groove 51 of the second side 59b of the profile rail 50 at the second position B - so that the cover is now inserted into the longitudinal grooves 51 of the profile rail 50 on both sides 59a and 59b and is thus mounted.

[0096] After the cover 40 has been inserted, it is then preferably inserted into or between the longitudinal grooves 51 in a non-clamping manner; in particular, the cover can lie loosely in and / or between the longitudinal grooves with slight play in the assembled state. In this case, an elastic twisting or twisting of the cover 40 along the longitudinal direction 56 can occur between positions A and B. In a preferred embodiment, the cover cross-section is not deformed or is only slightly deformed (especially since this would require force), but is preferably twisted or twisted essentially only over the length of the cover (which requires less force than deformation).In particular, since a twisting of the order of magnitude of the offset of the longitudinal groove 51 relative to the upper edge of the profile is sufficient – ​​which is usually kept low, especially with essentially flush covers – the force required for insertion can be reduced or minimized compared to other solutions. In particular, in conjunction with a grinding insertion of the cover 40 over a greater length of several millimeters of the longitudinal groove edge, which occurs only on one side of the cover, while the other side of the cover is free or already inserted in the longitudinal groove 51, the force required can be further optimized.

[0097] Fig. 5c again shows a partial section of the exit area of ​​the cover 40 from the roller 30, as shown in Fig. 5a. An example of an embodiment of the previously mentioned holding elements 35c in the form of spring-loaded hooks or lugs that engage under the lower web of the longitudinal groove 51 is more clearly visible. With these, the roller 30 - once plugged onto the profile rail 50 - is held to the profile rail, preferably even overhead. For example, when installing ceiling lighting, the roller 30 does not have to be held permanently, but rather holds itself to the profile rail, which, for example, simplifies or enables the relocation of a ladder during installation. The pressure force or contact force 72 is accordingly no longer required in this embodiment from Fig. 5a to Fig. 8 - apart from a one-time clipping of the roller 30 into the profile rail 50 (i.e., for the engagement of the holding elements 34d).Accordingly, after the cover 40 has been inserted, the roller 30 can be removed or tilted from the profile rail 50 with a single effort, especially after the cover 40 has been cut to length, for changing the roller 31, etc.

[0098] Also visible is the counterholder 35 as the lower part of the rail guide 35. Between the counterholder 34 and the rest of the outer housing 32, the cover 40 is guided in the roller 30, for example in a form identical or functionally similar to that shown in Fig. 5b. Specifically, the cover 40 is guided such that it has the desired height relative to the longitudinal groove 51 at the desired position A or B on the desired side. As will be apparent to a person skilled in the art, the specific geometric design can optionally also be different and at least one of the functions of the present invention can be achieved, for example, mirror-inverted, with different spacing or design or shape of the guides.

[0099] Fig. 6a shows, using the example of the embodiment of Fig. 5a, an optional option, which can also be considered an independent invention, for simple, safe, and correct cutting of the cover 40 mounted on the profile rail 50 with the roller 30. In this case, the device 39 provides for separating, cutting, or at least scoring the cover 40 at a defined position and / or angle, for example, with an externally provided cutter knife 44 shown here.

[0100] In Fig. 6b, as a partial section of Fig. 5a and as an exemplary embodiment, the roller 30 has a device 39 for cutting to length using a separating or cutting tool. In this case, the device 39 defines, in particular, a position and preferably also an angle (e.g., 90 degrees or 45 degrees) to the profile 50. In the example shown, specifically flush and parallel to the profile rail end or to an end cap 58. In other variants, instead of the blade 45 of the knife shown, an internal blade 45, a saw blade, or scissors, etc., can also be provided or intended.

[0101] Fig. 6c shows an example of a lighting profile produced with this method, with LED strips 52 inside the profile rail 51 and the cover 50, which ends exactly with the end cap 58 - without the need for length measurements or prior or subsequent separate manual cutting.

[0102] Fig. 6d again shows a sectional view of a section around the device 39 from Fig. 6b. The roller 30 mounted on the profile rail 50 is moved along the profile until it strikes the profile end cap 58 with a stop 34b of the rail guide or the counterholder 34. Using an externally or internally provided blade 45, the device 30, which is appropriately positioned and aligned with respect to the stop 34d, can then safely and reliably cut off the cover 40 at the correct location and angle. If the roller 30 is removed after cutting, the end of the cover 40 created by the cutting process, which may not yet have been inserted into the longitudinal grooves by the roller, can be pressed into the grooves by hand to achieve the result shown in Fig. 6c.

[0103] Fig. 7 illustrates an example of one of the possible embodiments of a guide for the cover 50 in the roller 30 according to the invention. Reference is also made to Fig. 5b. Shown at the top is the first side 59a, in which the cover is inserted in position A into the corresponding first longitudinal groove 51a of this profile side. The cover 40 and its guide in the outer housing 32, or rather its counterholder 34 and / or rail guide 35, are shown in solid lines. The respective profile rail side 59a, 59b with longitudinal groove 51a, 51b and the webs that form them, as well as a side view of the corresponding profile cross-section, are shown in broken lines.

[0104] Fig. 8 shows a view of the roller 30 from below - that is, from the side that is placed on the profile rail 50 or clipped in with the holding clips 35c, for example, under the lower web of the longitudinal groove 51. Special attention is paid here to the rail guide 35 of the outer housing 32 and the counter-holder 34. In the same position as in Fig. 7 above, positions A and B and their longitudinal distance 74 can be seen here. At positions A and B, the cover 40 is not only positioned / guided vertically as shown above in Fig. 7, but also positioned / guided laterally, which can be seen at the lateral outlets in areas A and B, at which the cover first exits laterally on each side.

[0105] As will be obvious to those skilled in the art, the embodiments and approaches shown or described here in various figures can also be combined and interchanged in accordance with the invention in a manner different from that shown.
