The The invention relates to a maintenance cover, in particular inspection flap for reversibly closing an opening in a wall comprising a frame connectable to the wall and one for closing the opening with the Frame releasably connectable cover comprising at least a cover plate.

Under a maintenance cover, in particular access door, is a Flap understood the reversible release of openings in walls, in particular ceilings or walls on maintenance channels or shafts. This will provide access to below the ceiling or behind walls arranged electrical supply lines and / or heating and plumbing installations possible. The flap is used for service and revision work, under which as a rule control, repair or conversion work be understood, opened and, where appropriate, depending on Execution also completely from the wall respectively Ceiling removed. After the service work, the flap put back on and closed.

Such maintenance flaps are known in different versions from the prior art. Representative is here on the pamphlets DE 201 04 472 U1 and DE 2002 01 036 U1 directed. These can be used as preassembled units from a frame and a cover plate in the openings. In these, the frame for attachment to the wall and for insertion into the opening provided in the wall opening in the form of the inspection opening is formed from angle profile pieces, each of which abuts one leg on the outside of the wall and the other on the peripheral wall surface of the inspection opening. The opening formed by the frame member is closed with a cover plate, usually made of plasterboard or other preferably refractory material. There are different possibilities with regard to the construction and handling of the opening of the flap. In a frequently applicable form, the cover plate is pivotally connected to the frame member, wherein the arrangement of the joints takes place on a side surface in rectangular design of the cover plate.

at Versions with separate front and back These are about a frame element in their position to each other fixed. The frame element is preferably designed as a profile frame and may preferably be made of a metallic material, for example Aluminum or plastic. Other versions are also possible.

In terms of the arrangement and control of the individual emission sources exist a variety of ways. These will be between Built in front and back of the cover, where In addition, further functional elements can be integrated between them are, for example, light guiding structures, diffusers for uniform Light distribution and / or photoluminescent films or layers, which are suitable to change the light color, for example Light blue LED's turn into white light, which is the Access to cheaper blue LED's possible.

In In a first embodiment, the individual LEDs are over at least the area of the partial area of the cover plate, preferably arranged the entire cover plate and have regard their main beam direction to the front. In this case can on dispenses with a special light guide structure and a punctiform Radiation generated.

The individual LEDs are arranged, for example, on a printed circuit board and on this mitein other and / or connectable to an electrical supply line. In particular, the arrangement or even a single controllability of the individual LEDs allows the possibility of additional light effects, such as an emergency lighting with less LED's and / or less light output and / or a light output to form geometric shapes, such as an arrow to identify an escape route.

In A second embodiment comprises the illumination device at least one between the element forming the back side and the transparent sheet-like element arranged emission source with one or a plurality of LEDs and a light guide structure for concentration and emission of emitted by the LED's Light. This assumes the function of light bundling, Concentration and charisma as well as amplification. The light guide structure is characterized by the property, due to a stimulus emit light by irradiating light from LED's. The arrangement of LED's can be done in this case with any main emission direction. The Lichtleitstruktur may in a first variant with the at least partially transparent form element form a structural unit or is in a second variant on a separate planar transparent element executed. It can also the individual LEDs and the light guiding structure on a flat surface Element can be arranged.

According to another second, Particularly advantageous embodiment, the geometry and / or distances between the individual light guide surfaces be chosen such that over the entire surface a uniform light emission is achieved. The light intensity, viewed over the surface, is a function of dimensioning, geometrical execution, Properties and distances of the individual light guide surfaces. These are preferably as a function of sizing, geometric Form of execution of the mold element and the desired light distribution over set the surface of the mold element.

In terms of the specific design of the individual light guide surfaces exist a variety of ways. these can in the simplest case circular, oval or as a polygon be educated. Other geometries are also conceivable. Preferably However, screen-printed easily be applied structures selected. The screen printing process represents a particularly cost-effective Method is.

there is the illuminable transparent form element, preferably in one Integrated frame structure. The light-emitting diodes themselves can according to a first embodiment either be coupled directly to the mold element or attached to this. The Attachment can be positive, positive or cohesive respectively. This offers the advantage that the illuminated form element already in advance as a completely pre-assembled unit can be provided and without additional impairments integrated into a frame element, in particular a standard frame can be.

According to one second embodiment, the individual LEDs, in particular Light-emitting diode carrier, stored separately in the frame. Thereby can be on a local connection between form element and LED are omitted.

The individual LEDs may be the same or different in their main direction. The orientation and arrangement of the LEDs is preferably such that the light beam is parallel to the surface of the formula tes is shipped. However, an alignment at an angle to the surface is also conceivable. According to the desired effect to be achieved, the orientations of the individual LEDs can be the same or different. The supply takes place when arranged in the frame element thus always side of the mold element.

about a controller can then control the energy output and light intensity be adjusted by controlling the LED's. Because the LEDs are very are economical, even smaller areas are sufficient for the energy supply. In a particularly advantageous Execution are the individual LEDs either individually, in Groups or jointly controllable, so that here also different lighting effects can be achieved. The control is usually over a control device via connecting lines or wirelessly connected to the adjusting means of the emission source.

The Coupling of the cover plate with the frame can be done in various ways. All solutions are, however, characterized by a full release of the frame-restricted opening given is. The cover plate can do so with respect to the frame pivotable or completely removable from this be executed. In the case of pivoting occurs the articulation of the cover plate preferably hinged to the frame. The closure is realized via fastening means, in particular releasable closures. Preferably is a safety device especially for overhead installation provided that not complete pivoting on release allows the closures, but the cover plate spends in an intermediate position called security position. From this can when loosening the safety device the Cover plate then transferred to the fully swung-out state become. The locking mechanisms and / or the safety device can be based on form and / or adhesion. In this regard, any execution in the State of the art are used, since the locking devices and / or safety devices in a simple manner at the Rear side and / or the frame element of the lighting device are fastened.

In By analogy, these statements also apply to the possibility opening by movement perpendicular to the opening. In this case, preferably also releasable fastening means used, which allow attachment of the cover plate to the frame. Again, a safety device can be integrated. The Safety devices can in both cases implemented in a simple way via catching devices, especially fishing hooks.

The Locking mechanisms can be used in both cases preferably designed as compression spring closures become.

This includes at least one, in the sectional view in 1c illustrated emission source 10 , and at least one connection device 11 for the emission source 10 , The emission source 10 is depending on the design of the lighting device 9 either in the cover plate 8th integrated or attached to this. The connection device 11 is preferably at the opening to be closed 3 facing back 12 the cover plate 8th arranged and fastened. The one from the opening 3 groundbreaking front 13 the cover plate 8th is preferably so opposite the frame 6 can be arranged so that they are flush with the wall, depending on the desired design 4 concludes or projects in the desired manner.

The 1a illustrates a view on the back 12 the cover plate 8th in the installed state. The flush on the front on the surface of the wall 4 fitting frame 6 is illustrated with a broken line. The 1b illustrates a view on the front 13 and thus the lighting device 9 and 1c shows a sectional view AA through the maintenance cover 1 , Shown in the 1a to 1c the condition in which the maintenance cover 1 in the opening 3 covering functional position I is arranged. In this embodiment, the frame is in a particularly advantageous manner 6 for attachment to the wall 4 formed at least as L-profile, wherein the leg 14 of the L-profile the contact surface on the surface of the wall pointing away from the maintenance shaft 4 forms while the thigh 15 extends into the opening and preferably flush with the wall of the opening 3 is applied. Also indicated are means 16 for fastening the cover plate 8th at the frame 6 , These can vary depending on the desired opening mechanism for the cover 8th be executed differently. This will be in the 2a and 2 B still separately received. The attachment takes place in the illustrated case pivotable via fastening devices 26 in the form of hinge connections or pivot bearings on one side of the cover plate 8th , And for closing on at least one adjacent or opposite side arranged fastening devices, in particular closure devices 27 , preferably in the form of compression spring closures. Furthermore, it is a safety device 28 provided, which by way of example as a fishing hook 31 is executed.

The cover plate 8th is here preferably completely from the lighting device 9 educated. This includes a frame element 17 , which may be made in one piece or in several parts, preferably the frame element 17 In 1c is designed as a profile element, in the illustrated case at least U-shaped or C-shaped. The frame element 17 This includes two parallel, different lengths or the same length and over a bridge 20 interconnected profile legs 18 . 19 , where the profile leg 18 on the front side 13 and the profile leg 19 at the back 12 the cover 8th are arranged. The frame element 17 is to the contour of the inner circumference of the frame 6 adapted and serves to close the enclosed by this opening. The profile leg 18 is arranged and designed such that this in the closed state of the maintenance flap 1 preferably flush with the surface of the wall 4 concludes.

The lighting device 9 includes at least one emission source 10 , preferably in the form of individual LEDs 10.1 to 10.n , These are preferably on the frame element 17 arranged, the arrangement here at the bridge 20 which the profile legs 18 . 19 connects to each other and in installation position in the circumferential direction on the inner circumference of the opening 3 extends takes place. The arrangement takes place here on the inner circumference of the frame element 17 and based on the contour of the front 13 when projecting into a plane around its outer circumference. Other arrangements are conceivable. The arrangement of the individual LEDs 10.1 to 10.n preferably takes place with a selected main direction of illumination. This is preferably in the direction parallel to the wall 4 or to be closed opening area of the opening 3 aligned. The individual LEDs 10.1 to 10.n is at the front 13 a light guiding structure 21 assigned to the concentration and radiation of the individual LED's 10.1 to 10.n emitted or emitted light is used. In this lightweight structure 21 it may be an example in the case shown to a plate 22 or even a foil 23 act. Furthermore, in the case shown, it is preferable to use a transparent, flat form element 24 provided, which is the front 13 forms. The backside 12 is of a preferably non-transparent or only a transparent portion having flat element 25 formed, in particular a cover plate. This will ensure that over the individual LEDs 10.1 to 10.n emitted light at the front 13 is delivered. Depending on the design of the front 13 forming transparent sheet-like element 24 Here different effects can be achieved.

The 1c illustrates in a section of an axial section, the execution of the illumination device 9 , It can be seen that the lighting device 9 at least one at least partially transparent planar element 24 as well as the light guiding structure 21 includes, within the frame element 17 are arranged and fixed by this in their position. In a particularly advantageous embodiment, it is also conceivable, the Lichtleitstruktur 21 with the transparent flat element 24 as a structural unit. In this case, about the design of the Lichtleitstruktur 21 additional effects are created on the transparent sheet-like element.

The in the 1c illustrated embodiment is characterized by a sandwich-like structure in which the Lichtleitstruktur 21 between the back 12 forming element 25 and the front 13 forming transparent surface element 24 is arranged.

In the in the 1a to 1c The illustrated embodiment is the maintenance cover 1 in the form of a revision flap 2 preferably around a planar element, in particular with a rectangular or square shape. Other designs for maintenance coverage 1 are also possible. This embodiment is characterized in that the otherwise provided with conventional inspection flaps plasterboard, the opening for the purpose of maintenance 3 in the wall 4 can release, by a lighting device 9 replaced. As a result, in a particularly advantageous manner, the function of the maintenance cover 1 with the arrangement of the lighting device 9 be summarized and thus easily accessible in the living area accessible inspection areas for supply lines are created. Furthermore, at the same time lighting devices 9 be installed in a simple manner without additional ceiling suspension or protruding on a ceiling, since in a particularly advantageous manner, such access panels also ensure access to electrical supply lines.

Regarding the way of concrete connection of the cover plate 8th to the frame 6 , in particular the attachment of the opening mechanism are a variety of ways. What matters is that through the frame 6 circumferentially limited opening 3 in the wall 4 over the cover 7 reversibly closable. It can according to 2a the cover 7 , in particular the cover plate 8th in the form of the lighting device 9 either by releasable fasteners 27 be lifted vertically from the wall. In this case, the funds include 16 by way of example at least two fastening means which cover the cover 8th , in particular the lighting device 9 , detachable with the frame 6 connect. This can be done in the simplest case by appropriate pins or glands. In a particularly advantageous embodiment and for easy Händelbarkeit, especially in the case of the formation of the cover plate 8th as a lighting device 9 , this is hinged on the frame 6 stored. This is in training the cover plate 8th in rectangular form at least one side by means of fastening devices 26 , In particular in the form of hinges to form a pivot axis with the frame 6 connected. The attachment to the other sides of the cover plate 8th then takes place preferably at least by means of another fastening device 27 ,

For safety when handling the maintenance cover 1 and to ensure an interruption or a decoupling of the connection device 11 From a supply network or a supply line, it is provided that in all versions, the maintenance cover 1 , in particular the cover plate 8th , not immediately the opening 3 is completely released, but placed in a position II, in which by a craftsman or other specialist the connection with the connection device 11 can be interrupted. In this case, the cover plate 8th or the lighting device 9 first in another intermediate position 11 be brought, wherein after separation of the emission source 10 from the supply lines by decoupling the connection device 11 from these the cover plate 8th in the full open position III is spent as desired. This can be characterized in that either the entire cover plate 8th is removed or only the pivoting into another position, preferably in ceiling installation in a position at right angles to the surface of the wall 4 he follows. This functional position is exemplary in the 2 B reproduced as functional position III. The angle can vary depending on the installation position and opening direction of the inspection flap 2 , in particular by pivoting about a horizontal or vertical axis vary. The intermediate position II is by means of a safety mechanism 28 , which can be realized in different ways, adjustable.

In the simplest case, commercially available spring-pressure closures are used as releasable closure mechanisms 30 for connection between the individual cover plate 8th and the frame 6 used, the intermediate function position II via a safety gear 31 is realized, which includes in the simplest case, at least one fishing hook, the pivoting after solving the connection via the spring pressure locks 30 the cover plate 8th in the functional position II holds. This can then be solved in a simple manner by the operating personnel.

In a version with spring-loaded closures 30 and the safety gear 31 it is a particularly advantageous embodiment, the in cooperation with at least one hinge connection on the opposite side of the cover plate 8th causes pivoting, at the same time the requirements for the safety in terms of the operation in the execution of the cover plate 8th as a lighting device 9 by placing them in an interruption of the connection between the emission source 10 and supply line provided position can be brought. This solution represents a particularly advantageous embodiment, these being commercially available elements. Such embodiments as a closure mechanism are already being offered, wherein in a particularly advantageous manner, the solution according to the invention can be integrated in a simple manner in these solutions by the otherwise existing plasterboard completely by the lighting device 9 is replaced, the lighting device 9 in this case one the back 12 forming plate, to which the connecting elements and fastening devices 26 . 27 and 28 can be arranged in the usual way.

Regarding the concrete fastening means for fixing the cover plate 8th , in particular lighting device 9 at the frame 6 , there are a lot of possibilities. This depends in detail on the concrete geometric design of the frame 6 from, further of the desired type of possibility of lifting the cover plate 8th , The individual connection can be made positively or non-positively or by a combination of the two. It is crucial that the execution of the connection is such that it is suitable, always the intermediate position II to solve the connection between lighting device 9 and supply line.

According to one particularly advantageous development, it is provided in addition to develop the lighting device with additional elements, For example, so-called diffuser devices can be used be used.

In contrast clarifies 3 a further development, in which preferably the function of Lichtleitstruktur 21 and at least partially transparent sheet element 24 is formed by an element, for example a corresponding disc.

In a particularly advantageous embodiment in the in 3 the exploded view is the Lichtleitstruktur 21 free of mechanical and / or electrical coupling with the individual LEDs 10.1 to 10.n. The light guide structure 21 may consist of an inorganic compound comprising a matrix for applying pigments containing, for example, titanium dioxide in the range between 10 and 30 vol .-%, most preferably about 20 vol .-%. The light guide structure may be formed as a grid comprising a plurality of light guide surfaces 29 , which may be evenly distributed over the surface or different.

As a rule, the only LEDs 10.1 to 10.n in this embodiment on a so-called light-emitting diode, here with 32 designated, stored. The arrangement on the single LED holder 32 can be done differently. This depends on the desired emission to be generated over the area of the cover 7 considered from. The arrangement may in particular vary with regard to the number of individual LEDs, their type, design and characteristics, and also with regard to the selected distance between the individual LEDs. The arrangement of the light-emitting diode carrier preferably takes place with respect to the illuminable, at least partially transparent planar element 24 laterally next to it, that is, parallel to the XY plane spanned by it. The light-emitting diode carriers 32 can be free from a direct connection with the at least partially transparent sheet-like form element 24 be executed, the fixation then by the the transparent sheet-like form element 24 enclosing, not shown here frame 17 takes place or are positively and non-positively with the transparent sheet-like form element 24 connected. To be with the individual of the LED's 10.1 to 10.n emitted light rays with the appropriate intensity on the desired and the illuminable at least partially transparent sheet-like element 24 spanned level to realize a corresponding illumination, is the light guide structure 21 intended. This is according to the 1 between the at least partially transparent planar element 24 and the back 12 forming element 25 arranged or forms according to 3 with the at least partially transparent planar element 24 a structural unit. Preferably, the light guiding structure 21 in both cases free from a mechanical or direct electrical coupling with the individual LEDs or the light-emitting diode carriers 32 , However, this is illuminated and serves to amplify and distribute the light emitted via the LED emitted light over the entire surface of the transparent mold element 24 ,

The lighting device 9 can be executed in different ways. In a particularly advantageous manner, LED structures are used, which can be integrated on an endless belt and according to the design of the frame can be inserted at this. Furthermore, it is also conceivable, depending on the design, to equip planar elements with LEDs, whose emission direction is too is aligned at least in a direction component perpendicular to the front, preferably directly perpendicular to this.

The 4a and 4b illustrate in a simplified schematic representation in a view in the XZ plane of the transparent sheet-like element 24 the orientation of the individual LEDs 10.1 to 10.n a light-emitting diode carrier 32 , According to 4a are the main illumination directions of the individual LEDs 10.1 to 10.n each at the individual LED holders 32 aligned parallel to each other and in the same direction, the LEDs of each LED array are each directed to the center. Shown is the orientation with respect to a plane parallel to the XY plane. In contrast, illustrates the 4b an orientation at an angle to each other. The orientation of the individual LEDs 10.1 to 10.n is chosen such that they extend at an angle or radially to the center. It is also conceivable, as already stated, the individual lighting direction parallel to the transparent sheet-like element 24 perform. Such an embodiment is in the 4d exemplified. The angle of the orientation of the main illumination direction is denoted here by α, wherein the angle between the main illumination direction and the transparent surface element 24 spanned surface is preferably in the range of 0-45 degrees. An example of the alignment of the main illumination direction parallel to the surface is in 4c played.

Conceivable, but not shown here, is also an arrangement and orientation of the individual LEDs on one of the light-emitting diode carriers 32 with different main illumination direction, both in an XY plane and the XZ plane or the YZ plane.
