Description

[0001] The invention relates to a base plate with a base body having an upper side and a lower side pointing away from the upper side.

[0002] Furthermore, the disclosure relates to a mounting rail for installing floor panels for a surface, such as a path, wherein the mounting rail is substantially channel-shaped and is formed with a receiving opening for at least one floor panel.

[0003] Furthermore, the invention relates to a laying system with at least one base plate and optionally at least one installation rail.

[0004] Covering panels, installation rails for covering panels and installation systems with covering panels and installation rails are generally known and, for example, from DE 201 02 832 U1, RO 129 304 A0, US 2013 / 279 160 A1, DE 196 27 856 A1 DE 299 13 554 U1 and EP 0 849 525 A2. For example, covering panels are often used as floor panels for paths to provide a surface that can be walked on and / or driven over by vehicles. In particular, the top side of the floor panel can provide the surface. A path can, for example, be a footpath, a road, a parking lot, but also a train platform, an area in or near an airport terminal or in an exhibition hall. Alternatively, covering panels are used to provide wall or ceiling surfaces. The surface can be outside or inside a building.Installation rails can facilitate the positioning of paving slabs during path construction and provide space beneath the paving slab for installation of fluid lines, for example. In installation systems, the paving slabs and installation rails can be adapted to each other and to the path being constructed.

[0005] If the decking slab is laid on a floor to provide the surface of the path, the decking slab is called a floor slab. If the decking slab is attached to a wall to provide the surface of the wall, the decking slab can also be called a wall slab. If the decking slab is attached to a ceiling to provide the surface of the ceiling, the decking slab can also be called a ceiling slab.

[0006] For information or orientation, information content or orientation signs, such as text, pictograms, or arrows, are applied to surfaces. However, the information and orientation signs cannot be easily changed, so the signs cannot be modified flexibly.

[0007] The invention is therefore based on the object of providing a surface that is easy to prepare or produce by means of floor panels, whereby information or orientation instructions can be flexibly changed.

[0008] For the base plate mentioned at the outset, the object is achieved in that the underside has a receiving recess which is open in the direction away from the top side for at least partially receiving a lighting device. The base body has at least one light-permeable and at least one light-impermeable section. The at least one light-permeable section extends from the top side to the receiving recess. The base body has a lateral side connecting the top side to the underside, wherein the lateral side has an attachment element for attaching the base plate to a mounting rail. The receiving recess can also be referred to as a receiving depression or a receiving recess. The attachment element is designed as a groove extending parallel to the top side.

[0009] The formation of the base body with the at least one light-permeable and the at least one light-impermeable section as well as the formation of the lateral side with the attachment element can each be advantageous in itself and independently of one another.

[0010] The mounting rail may have a side wall adjacent to the receiving opening, wherein the side wall is provided with a counter-attachment element. The counter-attachment element protrudes from the side wall.

[0011] For the installation system mentioned at the outset, the object is achieved according to the invention in that the at least one base plate is the base plate according to the invention and the at least one installation rail is the installation rail according to the invention.

[0012] The mounting element and counter-mounting element allow the base plate to be easily attached to the recessed rail, with the counter-mounting element being able to specify the installed position of the base plate. A light source that backlights the translucent section can, for example, be switched on and off, or its light color can be changed, allowing information or orientation instructions to be changed quickly and easily.

[0013] The invention can be further improved by additional embodiments, each advantageous in itself and, unless otherwise stated, readily combinable. These further possible embodiments and their advantages are discussed below.

[0014] According to one possible embodiment, the base plate has one lateral side and another lateral side facing away from the one lateral side, as well as an additional attachment element. An advantage of this embodiment can be that the base plate can be secured against unauthorized removal from its installed position thanks to the additional attachment element, while the base plate is easy to install.

[0015] According to one possible embodiment, the additional attachment element is arranged at a distance from the first attachment element. An advantage of this embodiment may be that the base plate can be better secured against unauthorized removal from its installed position due to the distance between the attachment elements, while also being easy to install.

[0016] According to one possible embodiment, the further attachment element is arranged between the lateral sides facing away from each other.

[0017] According to a further possible embodiment, the further attachment element is arranged centrally between the two lateral sides.

[0018] According to a further possible embodiment, the further attachment element is arranged closer to one lateral side than to the other lateral side.

[0019] According to a further possible embodiment, the further attachment element is arranged closer to the further lateral side than to the one lateral side.

[0020] An advantage of this design may be that the base plate can be better adapted to the structural conditions due to the different possible positions of the additional attachment element and can be secured against unauthorized removal from the installed position, whereby the base plate is easy to install.

[0021] According to another possible embodiment, the additional attachment element is arranged on the further lateral side. An advantage of this embodiment can be that by arranging the attachment element on the further lateral side, the distance between the attachment elements can be chosen as large as possible, thus securing the base plate particularly securely against unauthorized removal from its installed position.

[0022] According to a further possible embodiment, the top side, the bottom side and the one lateral side extend along a longitudinal direction of the base plate.

[0023] According to another possible embodiment, one attachment element and the other attachment element are arranged in the same position along the longitudinal direction. An advantage of this embodiment can be that the arrangement of the attachment elements makes it particularly secure to prevent unauthorized removal from the installed position. Furthermore, the arrangement of the attachment elements can prevent the floor panel from tilting during installation.

[0024] According to one possible embodiment, at least one attachment element and, if provided, optionally also the additional attachment element, extend longitudinally along the entire length of the floor panel, and in particular along the respective lateral side. An advantage of this embodiment can be that the attachment elements can be used to secure the floor panel particularly securely against unauthorized removal from its installed position. Furthermore, the arrangement of the attachment elements can prevent the floor panel from tilting during installation.

[0025] According to another possible embodiment, the attachment elements are arranged symmetrically on the lateral sides facing away from each other. An advantage of this embodiment can be that the floor panel can be installed particularly easily, for example, in two opposite orientations.

[0026] According to one possible embodiment, the further attachment element has an opening extending from the top side to the bottom side, which runs parallel to one lateral side and optionally perpendicular to the top side and / or the bottom side. A height direction of the base plate can run perpendicular to the longitudinal direction and from the bottom side to the top side. The height direction can be aligned perpendicular to the top side. The opening can extend along the height direction. An advantage of this embodiment can be that a holding means, in particular a mechanical holding means such as a force-fitting or form-fitting holding means, can be inserted into the opening and interacts with a counter-attachment element to secure the base plate. According to possible embodiments, the holding means can be, for example, a pin with part of a bayonet catch, a rivet or a screw.The further attachment element may comprise the holding means and / or the opening.

[0027] According to one possible design, the opening opens into the receiving recess or into a separate recess formed in the underside. An advantage of this design may be that a counter-holding element can be arranged in the receiving recess or in the separate recess of the installed floor slab, so that the counter-holding element does not hinder the installation of the floor slab.

[0028] According to one possible embodiment, the floor panel has at least one channel-shaped cable groove that opens from the top side and runs parallel to one of the lateral sides and / or the longitudinal direction of the floor panel. An advantage of this embodiment may be that a cable can be arranged in the cable groove of the installed floor panel, so that the cable does not hinder the installation of the floor panel.

[0029] If the floor plate, along with the cable, is part of the installation system according to one possible design, the cable groove can be dimensioned so that the cable essentially fills the groove. One advantage of this design can be that unnecessary empty spaces are avoided, which can increase the load-bearing capacity of the floor plate.

[0030] According to one possible embodiment, the cable groove is provided by the receiving recess. An advantage of this embodiment may be that the base plate is easier to manufacture.

[0031] According to one possible embodiment, the base plate has several channel-shaped cable grooves. If the installation system according to one possible embodiment comprises this base plate and several cables of different thicknesses, each of the cable grooves can be dimensioned such that only one of the cables substantially fills the respective cable groove. An advantage of this embodiment can be that the cable can only be inserted into the cable groove intended for the respective cable, thus facilitating correct cable installation.

[0032] According to one possible embodiment of the receiving recess, the receiving recess can widen as it extends away from the upper side. For example, the receiving recess can have a clear width that extends parallel to the upper side and / or perpendicular to one lateral side and / or along the width direction of the base plate. The clear width can increase, in particular, in a conical section of the receiving recess.

[0033] According to one possible embodiment, the conical section of the receiving recess has an end facing the upper side, which is arranged at a distance from the upper side. At the end, the clear width can be one or the minimum.

[0034] According to one possible embodiment, the base plate has a through-opening that adjoins the receiving recess, in particular its conical section or its end, toward the top. The clear width of the through-opening can be smaller than the smallest clear width of the conical section. Alternatively, the smallest clear width of the through-opening can correspond to the clear width of the end of the conical section.

[0035] According to one possible embodiment, the base plate has a mounting opening that begins in the top of the base plate and extends toward the bottom of the base plate. The mounting opening can optionally connect the receiving recess to the top in a translucent manner through the through-hole.

[0036] The clear width or opening of the mounting opening may be larger than the smallest clear width or opening of the receiving recess or the through opening.

[0037] According to one possible embodiment, the mounting opening has at least one support for a translucent closure element at its end facing away from the top, to which the through-hole or the receiving recess can be connected. When the floor panel is installed, the translucent closure element can be positioned in the mounting opening on the support.

[0038] The receiving recess and the mounting opening as well as the optional through-opening can together provide an opening that extends continuously through the base plate along the height direction.

[0039] The base plate can be formed essentially as a cylinder with a base area defined by the cross-section of the cylinder running transversely to the longitudinal direction and can have at least the cable groove and optionally the receiving recess, the through-opening, and / or the mounting opening. The base plate can thus be formed as a continuously cast body. Alternatively, the base plate can be cast using a casting mold.

[0040] Alternatively, at least the mounting opening can be limited in and / or counter to the longitudinal direction, wherein at least the mounting opening can be formed by the casting mold or subsequently introduced.

[0041] According to one possible embodiment, the installation rail has an additional counter-attachment element, wherein the additional counter-attachment element is arranged at a distance from the one counter-attachment element, at least in its installed state. An advantage of this embodiment can be that the base plate can be secured against unauthorized removal from the installed position thanks to the additional counter-attachment element, while the base plate is easy to install.

[0042] According to one possible embodiment, the installation rail has one side wall and another side wall, between which the receiving opening is arranged. An advantage of this embodiment with two side walls flanking the receiving opening can be that the receiving opening is better protected from the environment, making it easier to insert the base plate into the receiving opening.

[0043] According to one possible embodiment, the further counter-attachment element is arranged between the side walls.

[0044] According to a further possible embodiment, the further counter-attachment element is arranged centrally between the side walls.

[0045] According to a further possible embodiment, the further counter-attachment element is arranged closer to one side wall than to the other side wall.

[0046] According to a further possible embodiment, the further counter-attachment element is arranged closer to the further side wall than to the one side wall.

[0047] An advantage of this design may be that the base plate can be better adapted to the structural conditions due to the different possible positions of the additional counter-attachment element and can be secured against unauthorized removal from the installed position, whereby the base plate is easy to install.

[0048] According to one possible embodiment, the additional side wall is arranged opposite the side wall having the counter-attachment element and has the additional counter-attachment element. An advantage of this embodiment can be that by arranging the additional counter-attachment element on the additional side wall, the distance between the counter-attachment elements can be selected as large as possible, in order to particularly securely secure the base plate against unauthorized removal from its installed position.

[0049] According to one possible embodiment, the additional counter-attachment element protrudes from a base of the installation rail toward the receiving opening. An advantage of this embodiment may be that the base can be designed flat without compromising the ability to attach the base plate to the counter-attachment element.

[0050] According to one possible embodiment, the additional counter-attachment element is formed, at least in sections, as a mounting wedge that can be inserted between the additional side wall and one lateral side of the base plate inserted into the installation rail. The counter-attachment element can thus include the mounting wedge. An advantage of this embodiment can be that the additional mounting element can be easily inserted without tools.

[0051] According to one possible embodiment, the additional side wall is shorter than one side wall in a vertical direction of the installation rail running perpendicular to the floor. An advantage of this embodiment may be that the mounting wedge, when inserted, does not protrude vertically beyond one side wall and / or the base plate inserted into the installation rail.

[0052] According to one possible embodiment, the mounting wedge has two side surfaces that enclose an angle of less than 90° between them, wherein one of the side surfaces comprises the projecting or recessed part of the counter-mounting element. The angle can be an acute angle and, for example, less than 45°, 35°, 25°, 15°, or 5°. The projecting or recessed part can be arranged closer to a thicker end than to a thinner end of the mounting wedge. When the mounting wedge is inserted, the projecting or recessed part can face the receiving opening. An advantage of this embodiment can be that the mounting wedge is easy to insert and the base plate is easy to secure in its inserted position.

[0053] The projecting or recessed part can be arranged on the adjacent side of a right-angled triangle describing the attachment wedge.

[0054] According to one possible embodiment, the installation rail has a spacer projecting away from the installation rail on an outer side of one side wall and / or the other side wall. An advantage of this embodiment can be that at least one free end of one side wall and / or the other side wall can be moved away from the receiving opening when the installation rail is installed. If the one attachment element and / or the other attachment element is arranged closer to the free end than to a fixed end of the respective side wall opposite the free end, the attachment element can be easily moved away from the receiving opening together with the free end.If one attachment element and one counter-attachment element, or the further attachment element and the further counter-attachment element, engage with each other when the base plate is securely attached to the installation rail, so that the base plate is positively attached to the installation rail, i.e., fastened to it, this positive attachment can be opened by moving the respective attachment element. When the installation rail is installed, the spacer can rest against another element, such as another installation rail or a standard base plate, or against a solid floor or wall.

[0055] According to one possible embodiment, the installation rail has a longitudinal direction along which at least one side wall extends. Between one side wall and the other side wall, a width direction of the installation rail runs perpendicular to the longitudinal direction. A height direction of the installation rail runs perpendicular to the longitudinal direction and the width direction, for example, from the floor toward the receiving opening.

[0056] According to one possible embodiment, the spacer has a substantially L-shaped cutout transverse to the longitudinal direction of the installation rail, so that the spacer, together with the respective side wall, forms a U-shaped joint opening opposite to an insertion direction in which the base plate can be inserted into the installation rail.

[0057] The outer side facing away from the mounting rail, which can run parallel to the side wall, can be spaced apart from the outer side of the side wall. If the counter-attachment element is designed as a projection, the counter-attachment element has a height transverse to the longitudinal direction that extends from an inner side of the respective side wall to the free end of the counter-attachment element. If the attachment element is designed as a projection, the attachment element has a height transverse to the longitudinal direction that extends from the respective lateral side to the free end of the attachment element. According to one possible embodiment, the height is less than or equal to the distance.

[0058] According to one possible embodiment, the recessed track has a mounting device for captively accommodating a light source. Together with the base, the mounting device can have a U-shaped cross-section transverse to the longitudinal direction and open away from the base. An advantage of this embodiment can be that the light source can be easily and correctly positioned attached to the recessed track.

[0059] According to one possible embodiment, the receiving device has two opposing side legs, with a positioning projection arranged at least on the inner side of one of the side legs facing the other side leg. An advantage of this embodiment can be that full-surface contact between the inner side and the lamp is avoided. Any deformations or dirt present on the outer side of the lamp therefore do not impair the positioning of the lamp, or at least have a minor impact.

[0060] According to one possible embodiment, the installation rail has a positioning device for receiving and, if possible, captively holding a cable. Together with the base, the positioning device can have a U-shaped cross-section transverse to the longitudinal direction and open away from the base. An advantage of this embodiment can be that the cable can be easily and correctly positioned in the installation rail.

[0061] According to one possible embodiment, the positioning device is arranged at a distance from one side wall and / or from the other side wall. Alternatively, the positioning device can be formed on one side by one side wall or by the other side wall.

[0062] If the installation rail, together with a cable, is part of the installation system according to one possible design, the positioning device can be dimensioned such that the cable essentially fills the positioning device. One advantage of this design can be that unnecessary empty spaces are avoided.

[0063] According to one possible embodiment, the installation rail has multiple positioning devices. If the installation system according to one possible embodiment comprises this installation rail and several cables of different thicknesses, each of the positioning devices can be dimensioned such that only one of the cables essentially fills the respective positioning device. An advantage of this embodiment can be that the cables can only be inserted into the positioning device intended for the respective cable, thus facilitating correct cable installation.

[0064] The installation rail can be designed as a cylinder with a base defined by the cross-section of the installation rail running transversely to the longitudinal direction and having a base, a side wall with a counter-attachment element, and optionally also the other elements and fixtures. The installation rail can therefore be designed as a continuous cast body.

[0065] Possible embodiments of a further base plate according to the invention and a further installation rail according to the invention are described below. The features of this further base plate according to the invention and this further installation rail according to the invention can be combined with the features of the above-described base plate according to the invention and the above-described installation rail according to the invention, unless this is explicitly excluded.

[0066] The installation system described below may include the floor panels and installation rails described above and / or those described below. The method for providing indications on a surface may utilize the floor panels and installation rails described above and / or those described below.

[0068] According to one possible embodiment, the attachment element extends completely across the lateral side of the base body along a width direction parallel to the top and / or bottom. An advantage of this embodiment may be that the base plate is easier to install.

[0069] According to one possible embodiment, the base plate has a receiving tray that forms the receiving recess and is at least partially embedded in the base body. An advantage of this embodiment may be that the receiving recess can be easily prefabricated using the receiving tray.

[0070] Alternatively, according to one possible design, the receiving shell can be omitted. If the receiving shell is omitted, the receiving recess can be shaped differently and, for example, milled into a prefabricated base body. If the base body is manufactured by casting, the receiving recess can be formed during the casting process, for example, using a casting tool.

[0071] According to one possible embodiment, the base plate has a mounting shell inserted into the receiving recess. The mounting shell can be pressed into the receiving recess in such a way that it is held in place by force. Alternatively, the mounting shell can also be held in the receiving recess in a different way, for example by encapsulation, gluing, or screwing. The side of the mounting shell facing into the receiving recess can be shaped to complement the receiving recess. An advantage of these embodiments can be that the mounting shell can be easily inserted into the receiving recess and can provide a predefined mounting space for the light source.

[0072] According to one possible embodiment, the mounting shell has at least one fastening element for securing the illuminant and / or at least one other component. The other component can be an electrical or electronic component, for example, a circuit board equipped with electrical and / or electronic components.

An advantage of this embodiment can be that the illuminant or other components are easier to install.

[0073] According to one possible embodiment, the mounting shell forms a mounting recess that opens from the top to accommodate at least a portion of a light source. An advantage of this embodiment may be that the light source can be easily inserted into the mounting recess through the opening in the mounting recess or can shine into the recess through the opening in the mounting recess.

[0074] According to one possible embodiment, the mounting shell has a cover plate at its end facing the top. Depending on the orientation of the mounting shell, the cover plate can be referred to as the base or the roof of the mounting shell. The cover plate has at least one light-permeable section which is arranged such that it at least partially or even completely overlaps the at least one light-impermeable section of the base body. Overlapping can mean that a projection of the light-permeable section of the cover plate along a height direction of the base plate and / or along a lighting direction of the installed light source intersects or even penetrates the light-permeable section of the base body. An advantage of this embodiment can be that light emitted by the light source can easily reach the light-permeable section of the base body.

[0075] According to one possible embodiment, the base plate has a light source, wherein the light source and optionally the at least one other component are encapsulated in the mounting recess. An advantage of this embodiment may be that the encapsulation provides better protection for the light source and optionally the at least one other component from environmental influences, such as moisture or dust.

[0076] According to one possible embodiment, the mounting shell and the light source form a one-piece, manageable lighting module. The light source arranged in the mounting recess can be attached to the mounting shell either detachably or permanently and, for example, encapsulated with a potting compound located in the mounting recess. An advantage of this embodiment can be that the lighting module is easier to handle and install, and the light source, as part of the lighting module, can be better protected against damage and environmental influences, especially in the harsh environment of a construction site.

[0077] According to one possible embodiment, the illuminant comprises at least one LED and, for example, a plurality of LEDs or LED groups as a light source.

The installation system can comprise the external electrical or electronic components.Optionally, a cover can be provided to close the opening of the mounting recess facing away from the top of the base body. When closed, the cover can form a watertight seal against the base body and / or the mounting shell. One advantage of this design can be that the base plate is flexible, easy to manufacture, and durable.

[0078] According to one possible embodiment, the mounting shell is attached to the receiving shell, to the receiving recess and / or to a section of the base body arranged outside the receiving recess in a captive and non-destructive manner.

[0079] One advantage of this design is that the mounting tray is easily replaceable. If, for example, the light source is encapsulated in the mounting tray, it may not be easy to remove it. Consequently, if the light source needs to be replaced, the mounting tray can be swapped along with the light source.

[0080] According to one possible embodiment, the illuminant is attached to the mounting shell, for example, by means of positive or non-positive fastening elements, or by encapsulation. According to one possible embodiment, the mounting shell and the illuminant can be connected to each other in a single, manageable, integral manner. One advantage of this embodiment may be that the base plate is easier to install.

[0081] According to one possible embodiment, the receiving tray has two fastening projections, each extending away from the receiving recess. An advantage of this embodiment may be that the receiving tray is easy to attach to the base body.

[0082] According to one possible embodiment, the fastening projections may extend in opposite directions away from the receiving recess and / or be arranged on opposite sides of the receiving shell. An advantage of these embodiments may be that the fastening projections extending away from the receiving recess do not obstruct access to the receiving recess, or that the fastening projections arranged on opposite sides of the receiving shell can hold the receiving shell to the base body in such a way that the attached receiving shell does not exert any significant torque on the fastening projections.

[0083] According to one possible embodiment, at least one of the fastening projections is channel-shaped and opens away from the top side of the base plate. The channel formed by the channel-shaped fastening projection can also be provided in the base body and in particular in its underside pointing away from its top side, particularly if the receiving tray is omitted. The channel can open away from the top side and extend from the receiving recess to a lateral side of the base body connecting the top and bottom sides. Optionally, multiple channels can be provided. If multiple channels are provided, they can be arranged on different sides or on a selected side of the receiving recess. The at least one channel can open into the receiving recess.An advantage of these designs can be that connecting cables for the illuminant can be easily guided in the at least one channel without them being squeezed by the base body when the base plate is installed.

[0084] According to one possible embodiment, the fastening projections are at least partially recessed into the base body. An advantage of this embodiment can be that the underside of the base body rests flatly on the base plate when installed, and protruding fastening projections cannot cause the base plate to tip over.

[0085] According to one possible embodiment, the receiving tray has outer sides facing away from the receiving recess. At least one of the fastening projections protrudes from each of the outer sides. At least one fastening element is arranged on selected outer sides. A projection of one of the fastening elements overlaps one of the fastening projections along the vertical direction of the base body running from the top to the bottom. An advantage of this embodiment can be that the receiving tray is easy to attach to the base body.

[0086] According to one possible embodiment, at least one of the fastening elements has a screw receptacle for a fastening screw that secures the mounting shell. Optionally, and especially if the mounting shell is omitted, the base body can be provided with the screw receptacle. An advantage of this embodiment can be that the mounting shell can be easily and detachably attached.

[0087] According to one possible embodiment, a side of the base plate facing away from the attachment element is formed with a retaining projection. An advantage of this embodiment can be that the base plate is secured against unauthorized removal from its installed position on opposite sides due to the retaining projection provided on the side facing away from the attachment element.

[0088] According to one possible embodiment, the retaining projection is arranged at a distance from the top side. According to one possible embodiment, the retaining projection is flush with the underside of the base plate. An advantage of this embodiment may be that the base plate can rest on the retaining projection and one of the side walls of the mounting rail, making it easy to position.

[0089] According to one possible embodiment, the base plate and, for example, its base body have a channel-shaped cable groove that opens from the top and leads from the receiving recess to one of the lateral sides. The cable groove can be formed separately or through the aforementioned channel. An advantage of this embodiment can be that the base plate can be easily and flexibly supplied with power and / or signals for the lighting device.

[0090] According to one possible embodiment, the installation rail has a base contacting the side wall and at least one support projection extending from the base toward the receiving opening. The support projection is arranged at a distance from the counter-attachment element. An advantage of this embodiment can be that the base plate or another plate, which may be part of the path, rests on the support projection when installed and is supported by the support projection and optionally by the counter-attachment element, so that a free volume remains between the base plate or the other plate and the base of the installation rail. This free volume can be provided for the installation of connecting cables.

[0091] According to one possible embodiment, the side wall projects beyond the at least one support projection from the base plate toward the receiving opening. An advantage of this embodiment may be that the side wall defines a desired position of the base plate in a horizontal direction.

[0092] According to one possible embodiment, the installation rail has two side walls. The receiving opening is arranged between the side walls. The at least one support projection is arranged closer to one of the side walls than to the other. An advantage of this embodiment can be that the free volume can be adapted to the space requirements of the connecting cables.

[0093] According to one possible embodiment, the at least one support projection is arranged farther away from the side wall having the counter-attachment element than from the other side wall. An advantage of this embodiment may be that the locations where the base plate or the other plate is supported are further apart, thus providing even more stable support for the base plate or the other plate.

[0094] According to one possible embodiment, the at least one support projection is adjacent to one of the side walls. An advantage of this embodiment can be that the free volume is maximized and the base plate or the other plate is supported even more stably.

[0095] According to one possible embodiment, the side wall adjacent to the at least one support projection forms one side of the support projection. An advantage of this embodiment may be that a separately formed side wall can be omitted, thus saving material and installation space.

[0096] According to one possible embodiment, the at least one support projection has at least one hollow space extending along a longitudinal direction of the mounting rail. An advantage of this embodiment may be that the weight of the mounting rail is not unnecessarily increased, making the mounting rail easier to handle.

[0097] According to one possible embodiment, the at least one support projection has two cavities extending along a longitudinal direction of the mounting rail. The cavities are separated from each other at least in sections by an inner wall. According to one possible embodiment, the cavities are arranged one behind the other perpendicular or parallel to the receiving opening. An advantage of this embodiment can be that the mounting rail can be manufactured in a weight-saving manner while still having a sufficiently stable support projection.

[0098] According to one possible embodiment, the at least one support projection has at least one interruption along its longitudinal direction. An advantage of this embodiment may be that connecting cables can be routed from one side of the support projection to the other side of the support projection.

[0099] According to one possible embodiment, the installation rail has a plurality of support projections. The support projections are arranged at a distance from one another transversely to a longitudinal direction of the installation rail. An advantage of this embodiment can be that several free volumes are available, allowing the base plate or the other plate to be supported even more stably, or allowing multiple, possibly different, base plates to be supported.

[0100] According to one possible embodiment, the base plate adjoins the side wall of the installation rail that has the counter-attachment element. A cover plate can be arranged between the base plate and the other side wall as another plate. The cover plate can be a conventional base plate with the same or different dimensions as the base plate according to the invention, but without translucent sections, or another base plate according to the invention. An advantage of this embodiment can be that the installation system is easier to install and adaptable to surrounding areas of the path.

[0101] According to one possible embodiment, the cover plate rests on the at least one support projection. An advantage of this embodiment may be that the installation system can be installed easily and with similar steps.

[0102] According to one possible embodiment, the cover plate rests on the retaining projection and / or on at least one of the support projections. An advantage of this embodiment may be that the cover plate can be installed securely with little effort.

[0103] According to one possible design, the cover plate is attached to the mounting rail. An advantage of this design is that the cover plate itself, and optionally also the base plate, are secured against accidental removal.

[0104] According to one possible embodiment, the cover plate is attached to the at least one support projection. An advantage of this embodiment may be that the attachment of the cover plate can be provided flexibly and adapted to the circumstances of the path.

[0105] According to one possible embodiment, the installation system includes a fastening element that secures the cover plate to the installation rail. The fastening element is positioned closer to a side adjacent to the base plate than to a side facing away from the base plate. An advantage of this embodiment may be that mobility of the cover plate, possibly caused by mechanical play, does not result in the base plate being inadequately secured against accidental removal due to the play.

[0106] According to one possible embodiment, the channel-shaped cable groove opens toward the at least one support projection and, for example, toward its interruption. An advantage of this embodiment may be that connecting cables for the light source are easy to install.

[0107] According to one possible embodiment, a light source is arranged in the receiving recess. Connecting cables leading to the light source run through the cable groove. An advantage of this embodiment can be that the installation system is simple and can be installed with a low overall height, with connecting cables being able to be laid at least partially or in sections within the installation system.

[0108] According to one possible embodiment, the connecting lines extend through the interruption of the at least one support projection. An advantage of this embodiment may be that connecting lines can be routed from one side of the support projection to the other side of the support projection.

[0109] According to one possible embodiment, the base plate has a plurality of illuminants and a plurality of translucent sections. According to one possible embodiment, the base plate has one illuminant per translucent section. The plurality of illuminants can have a common circuit board and / or be separately switchable. An advantage of this embodiment can be that the translucent sections can be selectively backlit.

[0110] According to one possible embodiment, the installation system comprises a control system for manually or automatically controlling the at least one light source. An advantage of this embodiment may be that no additional control systems that would have to be adapted to the installation system are required.

[0111] According to one possible embodiment, the control system is designed to operate selected or all lighting devices together and / or individual lighting devices separately. An advantage of this embodiment may be that instructions or orientation aids can be flexibly changed.

[0112] In order to be able to install the installation system easily and to provide information flexibly, the base plate has translucent sections that can be selectively backlit by at least one light source in order to make the information visible on the surface of the base plate.

[0113] Independently of or together with the floor panel, the installation rail, and / or the installation system, the invention can solve the problem by a method for providing information on a surface, in particular a path, a wall, or a ceiling, in which selected translucent sections of the floor are selectively illuminated from below in order to display information or orientation aids, for example as text, symbols, or pictograms, in a visible and flexibly changeable manner. One advantage of this solution can be that information or orientation aids can be flexibly changed. To provide the information, individual or multiple translucent sections can be selectively backlit.

[0114] For example, the floor can be designed as a platform, i.e., a footpath. Of course, the floor can also be the surface of a roadway, such as a street or a parking lot.

[0115] The installation system according to the invention can be used to carry out the method. To provide the information, the installation system can selectively backlight individual translucent sections of the floor slab or multiple floor slabs according to the invention.

[0116] For example, the routing system provides information about the location of the doors of a train that will soon stop at the platform. For example, areas of the floor where the train doors will be located are backlit. Sections where no train doors are expected may not be backlit or may be backlit differently. To guide people to the boarding areas where the doors are expected, sections of the floor and / or sections of the floor adjacent to the boarding areas can be backlit in a generally arrow-shaped manner.

[0117] The information can be position information, for example, marking the door positions of an expected train at the platform. Alternatively, the train position can be displayed as an information, for example if the train is shorter than the platform and / or if trains of different lengths are stopping at a platform. Furthermore, information about the occupancy of individual carriages or compartments of an expected train or a train already at the platform could be displayed. Warnings could also be displayed, for example if a train is about to pass the platform. The information can be designed as arrows, or as moving or changing, for example dynamic, patterns that indicate the expected stopping position of the train or the train doors.Furthermore, the warnings can be designed, for example, as different colors representing the occupancy of a carriage or compartment, for example, red for full, yellow for moderately full, and green for empty, or colors symbolizing first- and second-class compartments. A warning can be provided, for example, by at least one red and optionally pulsating or flashing cross. Multiple warnings can be provided, for example, along a platform edge, for example, when a train is about to pass through a station.

[0118] The signs can also be other warnings, for example, simulating a pedestrian crossing light on the ground, so that selected surfaces alternately display several colors, such as red, yellow, and green, or, like a classic pedestrian crossing light, several surfaces each display one of the colors red, yellow, and green. The signs can be displayed as surfaces or, for example, as lines and / or crosses or arrows that glow statically or pulsate or flash.

[0119] On a taxiway, instructions may be given as to the routes (runways) or parking positions to be used by an aircraft.

[0120] The distance to a target position, for example, the distance of an airplane or a car to its optimal parking position, can also be displayed as an indicator. Indications of different distances can be provided by different flashing frequencies.

[0121] The selective backlighting of individual sections of the floor can be adapted to specific circumstances. For example, the boarding areas can be adapted to different trains and / or trains that stop at different locations.

[0122] The train can communicate the positions of the train doors to the routing system directly or indirectly, for example by the train transmitting the distances between the train doors and the train, the routing system or an external system determining the stopping position of the train on the platform.

[0123] Alternatively, routes to destinations other than the boarding areas can be displayed. This allows for flexible display of routes for each person, for example, with a color assigned to each person or route. If a person is on one of the predefined routes, that route can be backlit in the predefined color. Other routes can be backlit differently.

[0124] For example, the person can carry a data carrier that can be read by the installation system, the data of which represents the person or the route and can be evaluated by the installation system.

[0125] The routes can, for example, be paths in a city center, at a trade fair or even in a parking garage or on a parking lot to guide vehicles to free parking spaces or to an exit, or people to their parked vehicles.

[0126] Multiple floor tiles can be combined to create larger clues or large-scale patterns. "Large" means at least larger than one floor tile.

[0127] Alerts can be triggered in a controlled manner, such as time- or event-driven. An event can be a sensor signal, the reaching of at least a predetermined weight, a predetermined number of people, the triggering of a light sensor, the triggering of a temperature sensor, etc. Sensor signals that reach different thresholds can result in different alerts.

[0129] The features of the embodiments described below can be combined independently, as already explained with regard to the embodiments.

[0130] Figure 1shows an embodiment of the base plate 1 according to the invention schematically in a top or plan view. The base plate 1 has a base body 2 with an upper side 3 pointing out of the plane of the drawing and a bottom side 4 opposite the upper side 3 and pointing into the plane of the drawing. In the embodiment shown, the base plate 1 has a substantially square shape. However, the base plate 1 can also be shaped differently and, for example, be rectangular, polygonal with exactly, more or fewer than four corners, or round, oval, or irregularly shaped. Lateral sides 5 - 8 of the base body 2 connect its upper side 3 to its underside 4. The lateral sides 5 - 8 can run perpendicular to the upper side 3. Alternatively, at least one of the lateral sides 5 - 8 can form an angle with the upper side 3 that is less than 270°.

[0131] The upper side 3 of the base body 2 can, in the installed state of the base plate 1, provide a surface of a path, for example a footpath or driveway.

[0132] The base body 2 has at least one light-permeable section and in the embodiment of the Figure 1 a total of six light-transmitting sections 9-14. The base body 2 can have more or fewer than six, and for example, two, three, four, five, seven, eight, nine, or between ten and twenty or even more light-transmitting sections.

[0133] At least one or all of the light-permeable sections 9 - 14 extend from the top side 3 through the base body 2. Preferably, one or all of the light-permeable sections 9 - 14 extend perpendicular to the top side 3 through the base body 2.

[0134] Along the upper side 3, the at least one light-permeable section 9 - 14 can be shaped as desired, for example curved. In the embodiment of the Figure 1 However, the light-transmissive sections 9 - 14 are straight and run along imaginary rays away from their common intersection point. The intersection point can be arranged at a distance from selected ones or from all of the light-transmissive sections 9 - 14. Three of the light-transmissive sections 9, 10, 11 and / or 12, 13, 14 can be arranged to run at an angle between 20° and 60° and, for example, at an angle of 45°. A central light-transmissive section 10, 13 can be flanked by two light-transmissive sections 9, 11 or 12, 14. The light-transmissive sections 9, 12 and / or 11, 14 can run at an angle to each other that is between 60° and 120° and, for example, 90°.

[0135] To connect the base plate 1 to a control system of a laying system, the embodiment of the Figure 13 Connecting cables 15, 16, 17, which extend through the lateral side 6 into the base plate 1. The number of connecting cables may be greater or less than three, depending on electrical or electronic requirements.

[0136] Figure 2 shows the embodiment of the Figure 1 in a schematic perspective view and with a light source 20.

[0137] The base plate 1 has a receiving recess 21 for the lamp 20 on its underside 4. The receiving recess 21 opens away from the top side 3. The light-permeable sections 9-14 extend from the top side 3 to the receiving recess 21.

[0138] In the example of Figure 2The receiving recess 21 is provided by a receiving shell 22 inserted into the base body 2. Alternatively, however, the receiving recess 21 can also be provided without the receiving shell 22 and in particular by the base body 2.

[0139] The illuminant 20 can be as in the embodiment of the Figure 2 and provided with a mounting tray 23. The mounting tray 23 can be inserted into the receiving recess 21 together with the illuminant 20. One side of the mounting tray 23, which faces into the receiving recess 21 when the mounting tray 23 is inserted into the receiving recess 21, can be designed to be substantially complementary to the receiving recess 21.

[0140] When inserted into the receiving recess 21, the mounting shell 23 can have a mounting recess 24 opening away from the upper side 3 of the base body 2, which in the view of the Figure 2is concealed by a cover plate 25 of the receiving shell 22. The lighting means 20 can be accommodated at least in sections in the mounting recess 24. The cover plate 25 can have at least one light-permeable section which is arranged such that it at least partially overlaps the at least one light-permeable section 9 - 14 of the base body 2. In the exemplary embodiment shown, the cover plate 25 of the mounting shell 23 has light-permeable sections 26 - 31 whose size, position and orientation essentially correspond to the light-permeable sections 9 - 14 of the base body 2. In particular, the number of light-permeable sections 26 - 31 of the mounting shell 23 can correspond to the number of light-permeable sections 9 - 14 of the base body 2.

[0141] The mounting shell 23 can be attached to the receiving shell 22 and / or the base body 2 in a captive and non-destructively detachable manner. Thus, the mounting shell 23 can have at least two fastening projections 32, 33 extending away from the mounting recess 24. The fastening projections 32, 33 can protrude from the receiving recess 21 when the mounting shell 23 is inserted into the receiving recess 21. For example, when the mounting shell 23 is inserted, the fastening projections 32, 33 can rest on an edge 34 of the underside 4 of the base body 2, which edge encircles the receiving recess 21 at least in sections.

[0142] The fastening projections 32, 33 may extend in opposite directions from the mounting recess 24 and / or be arranged on opposite sides of the mounting shell 23. Some or all of the fastening projections 32, 33 may be channel-shaped and open away from the end plate 25. In the embodiment of the Figure 2However, the fastening projections 32, 33 are bar-shaped and can be arranged at a distance from the end plate 25. For example, the fastening projections 32, 33 can be aligned with a free end, pointing away from the end plate 25, of a lateral side 35 of the mounting shell 23 that borders the end plate 25 at least on one side. The lateral side 35 can extend perpendicular to the end plate 25 and at least partially surround the end plate 25 and the mounting recess 24. Alternatively or in addition to the circumferential lateral side 35, the mounting shell 23 can have a plurality of lateral sides 35.

[0143] At least one or all of the fastening projections 32, 33 can be recessed into the base body 2 and, for example, into its edge 34. At least one of the fastening projections 32, 33 can have a through opening 36, 37 extending perpendicular to the end plate 25, which is designed to receive a fastening screw. The mounting shell 23 is fastened to the base body 2 and / or to the receiving shell 22 by means of the fastening screw or several fastening screws.

[0144] Figure 3 shows the embodiment of the previous figures schematically in another perspective view.

[0145] The end plate 25 of the mounting shell 23, like the upper side 3 of the base plate 1, essentially points into the plane of the drawing, so that the mounting recess 24 of the mounting shell 23 opens out of the plane of the drawing. The illuminant 20 is arranged in the mounting recess 24. The illuminant 20 is shown in the illustration of the Figure 3 but enclosed by a casting agent 38, so that the illuminant 20 in the Figure 3 is concealed by the encapsulating agent 38. The encapsulating agent 38 can essentially completely fill the mounting recess 24. The illuminant 20 and the mounting shell 23 can be secured to one another by the encapsulating agent 38 or otherwise, for example, in a force-fitting or form-fitting manner. If the illuminant 20 and the mounting shell 23 are secured to one another, they can together form a lighting module 39 that can be handled as a single piece.

[0146] The connecting lines 15, 16, 17 can extend through the lateral side 35 or through one of the lateral sides 35 of the mounting shell 23 into the mounting recess 24. The lateral side 35 can have an opening for each connecting line. In the exemplary embodiment shown, however, all connecting lines 15, 16, 17 run through a common opening 40 in the lateral side 35. To prevent the potting compound 38 from passing through the common opening 40 during potting, a closure plate 41 can be provided through which the connecting lines 15, 16, 17 extend. The closure plate 41 can seal off the connecting lines 15, 16, 17 and the lateral side 35, so that only insignificant amounts of the potting compound 38 can escape through the common opening 40, if any.

[0147] Figure 4shows the embodiment of the previous figures, wherein the illuminant 20 with the mounting shell 23 is inserted into the receiving recess 21 provided by the base body 2. The connecting cables 15, 16, 17 can run through a channel-shaped cable groove 42. The cable groove 42 can run through the base body 2 and in particular through its edge 34 and open away from the top side 3 of the base body 2. The cable groove 42 can extend from the receiving recess 21 to the lateral side 6 of the base body 2.

[0148] Figure 5shows the optional receiving tray 22 with the mounting tray 23, wherein the receiving tray 22 provides the receiving recess 21 and the mounting tray 23 is arranged in the receiving recess 21. The receiving recess 21 and the mounting recess 24 open in identical directions. The receiving tray 22 has receiving channels 43-45, wherein the fastening projections 32, 33 are inserted into the receiving channels 43, 44. The receiving channel 45 can be inserted into the cable groove 42 of the base body 2, and the connecting cables 15, 16, 17 can run through the receiving channel 45. The common opening 40 can be arranged between the receiving channel 45 and the mounting recess 24.

[0149] Figure 6 shows the mounting tray 23, which can be inserted into the receiving recess 21 of the base body 2 even without the receiving tray 22. Optionally, the mounting tray 23 can have the receiving channel 45 for accommodating the connecting cables 15, 16, 17.

[0150] Figure 7shows an embodiment of the installation rail 50 according to the invention in a schematic front view. The installation rail 50 can be designed for installing floor panels, and in particular floor panels 1 according to the invention, for a path. The installation rail 50 is essentially channel-shaped and formed with a receiving opening 51 for at least one floor panel 1. The installation rail 50 has a side wall 52 adjacent to the receiving opening 51. The side wall 52 is provided with a counter-attachment element 53 for the floor panel 1. In the illustrated embodiment, the counter-attachment element 53 protrudes from the side wall 52. Alternatively, the counter-attachment element 53 can be formed as a recess formed in the side wall 52, such as a groove.

[0151] The mounting rail 50 can have a base 54 contacting the side wall 52. Furthermore, the mounting rail 50 can have a support projection 55 extending from the base 54 toward the receiving opening. The support projection 55 can be arranged at a distance from the counter-attachment element 53. The side wall 52 can project beyond the at least one support projection 55 in a height direction H pointing from the base 54 into the receiving opening 51. This direction can be perpendicular to the base 54.

[0152] The mounting rail 50 can have a further side wall 56. The receiving opening 51 can extend between the side walls 52, 56. The at least one support projection 55 can be arranged closer to one of the side walls 52, 56 than to the other of the side walls 56, 52. For example, the support projection 55 is arranged farther away from the side wall 52 having the counter-attachment element 53 than from the other side wall 56.

[0153] The support projection 55 or a further support projection 57 can adjoin one of the side walls 52, 56, and in particular the side wall 56 opposite the side wall 52 having the counter-attachment element 53. The side wall 56, which is adjoined by the at least one support projection and in particular the further support projection 57, can form one side of the support projection 57. Furthermore, the side wall 56 can project beyond the at least one support projection 55, 57 in the direction away from the base 54.

[0154] In the example of Figure 7 The mounting rail 50 has several, and in particular three, support projections 55, 57, 58. Selected or all of the support projections 55, 57, 58 can have at least one cavity extending along a longitudinal direction L of the mounting rail 50. The longitudinal direction L extends in the Figure 1perpendicular to the plane of the drawing. The mounting rail 50 extends in the longitudinal direction L and can have a cross-section that is essentially constant along the longitudinal direction L, transverse to the longitudinal direction L. For example, the mounting rail 50 can be designed as an explosive body along its longitudinal direction L.

[0155] In a width direction B of the installation rail 50 running transversely to the longitudinal direction L, the support projections 55, 57, 58 can be arranged at a distance from one another.

[0156] The at least one support projection 55 or selected one or all of the support projections 55, 57, 58 can have at least one or even two cavities 59-62 extending along the longitudinal direction L of the installation rail 50. If the respective support projection 55, 57, 57 has two cavities 61, 62, these can be separated from each other at least in sections by an inner wall 63 of the support projection 55. In the embodiment of the Figure 7the cavities 61, 62 are arranged one behind the other perpendicular to the receiving opening 51 and / or to the bottom 54.

[0157] On an underside 63 of the base 54 facing away from the receiving opening 51, the installation rail 50 can have at least one spacer 64. If the installation rail 50 has a plurality of spacers 64, these can be arranged transversely to the longitudinal direction L and, for example, spaced from one another in the width direction B. For example, one spacer 64 can be aligned with one of the side walls 52, 56 perpendicular to the base 54, i.e., can be arranged directly in front of the respective side wall 52, 56 in the height direction H. Additionally or alternatively, one spacer 64 or a plurality of spacers 64 can be arranged between the side walls 52, 56. The spacers 64 can be substantially T-shaped, wherein the transverse line can be arranged at the end of the spacer 64 facing away from the top side 54.

[0158] The spacer 64 can also be designed to serve as a surface enlargement and / or additional anchoring point, for example as an undercut, for bonding and / or mounting the installation rail 50, for example in the mortar bed.

[0159] Figure 8 shows a schematic perspective view of an embodiment of the installation system 70 according to the invention. The installation system 70 is shown with the installation rail 50, with several base plates 1, and with several cover plates 71. The same reference numerals are used for elements that correspond in function and / or structure to the previous embodiments.

[0160] The floor panels 1 are arranged one behind the other along the longitudinal direction L. In the width direction B of the installation rail 50, which runs transversely to the longitudinal direction L, the floor panels 1 can be placed against the counter-attachment element 53. In order to prevent the floor panels 1 from being removed from the installation rail 50 in the height direction H, which runs transversely to the longitudinal direction L and the width direction B, the floor panels 1 have an attachment element 72 on the lateral side 8, which can be opposite the lateral side 6. The attachment element 72 can be shaped at least in sections to be complementary to the counter-attachment element 53 and can secure the position of the respective floor panel 1 in a form-fitting manner. In the Figure 8 In the embodiment shown, the attachment element 72 is designed as a parallel to the upper side 3 and / or to the Figure 8A recess extending from the non-visible underside 4 is formed in the lateral side 8. The recess is designed as a groove. The attachment element 72 and the counter-attachment element 53 can be shaped complementarily to one another.

[0161] When the base plate 1 is inserted into the installation rail 50, a width direction of the base plate 1 can run parallel to the longitudinal direction L of the installation rail 50. The attachment element 72 can extend completely over the lateral side 8 along the width direction B of the base plate 1, which runs parallel to the top side 3 and / or the bottom side 4.

[0162] On the lateral side 6 of the base plate 1 facing away from the attachment element 72, the base plate 1, and in particular its base body 2, can be formed with a retaining projection 73. The retaining projection 73 can be arranged at a distance from the upper side 3 and, for example, flush with the underside 4 of the base plate 1.

[0163] In the illustrated embodiment, the base plate 1 adjoins the side wall 52 having the counter-attachment element 53. The optional cover plate 71 can be arranged between the base plate 1 and the side wall 56, which is opposite the side wall 52 having the counter-attachment element 53.

[0164] The cover plate 71 can rest on the at least one support projection, on selected ones of the support projections, or on all of the support projections 55, 58, 57. The cover plate 71 can, in particular, be repeatedly releasably fastened to the mounting rail 50. For example, the cover plate 71 can be fastened to at least one of the support projections 55, 57, 58. For example, the support projection 58 to which the cover plate 71 is fastened can have a fastening element, such as a screw receptacle, wherein the cover plate 71 is fastened to the holding element and thus to the mounting rail 50 by means of a counter-fastening element 74, such as a screw.

[0165] The cover plate 71 can have, on its lateral side 75 facing the base plate 1, a counter-holding projection 76, which is arranged behind the holding projection 73 in the vertical direction H of the base plate 1 and, together with the counter-attachment element 53, prevents accidental removal of the base plate 1 from the installation rail 50. When the base plate is inserted, the vertical direction of the base plate 1 can run parallel to the vertical direction H of the installation rail 50 and extend from the underside 4 to the top side 3 of the base plate 1. The holding projection 73 and the counter-holding projection 75 thus overlap in the vertical direction H. In the context of this description, "overlap" means that a projection of one element in the said direction overlaps the other element.In particular, the holding projection 73 and the counter-holding projection 76 can contact each other or be spaced apart from each other when the base plate 1 and the cover plate 71 are arranged in the installation rail 50.

[0166] At least the support projection 55 arranged closest to the base plate 1 or adjacent to its lateral side 6 can have at least one interruption 77 along the longitudinal direction L. The interruption 77 can overlap the cable groove 42 of a base plate 1 inserted into the base rail 50 in the width direction B of the installation rail 50 and / or be aligned with it. The cable groove 42 can therefore open away from the side wall 52 and / or towards the support body 55 or towards its interruption 77. The support projection 55 can have a plurality of interruptions 77 which are spaced apart from one another along the longitudinal direction L of the installation rail 50 such that the cable grooves 42 of all or selected base plates 1 are each aligned with or overlap one of the interruptions 77.

[0167] The connecting lines 15, 16, 17 can extend through the cable groove 52 and the interruption 77 and extend between the at least one support projection 55 and the side wall 56 or between the support projection 55 and one of the support projections 57, 58.

[0168] Figure 9 shows the embodiment of the Figure 8 in a schematic sectional view, where the sectional plane is spanned by the width direction B and the height direction H. The longitudinal direction L points into the drawing plane.

[0169] In Figure 9 it can be clearly seen how the counter-holding projection 76 and the counter-attachment element 53 prevent the base plate 1 from being removed from the installation rail 50 along the height direction H when the cover plate 71 is fastened to the installation rail 50.

[0170] Furthermore, Figure 9 that the cavities 61, 62, in contrast to the embodiment of the Figure 7can also be arranged one behind the other along the width direction B. The inner wall 63 can therefore extend along the height direction H and the longitudinal direction L. The further features of the installation rail 50 of the embodiment of the Figures 8 and 9 can be the further features of the mounting rail 50 of the embodiment of the Figure 7 are equivalent to.

[0171] At least one support rail 78, 79, 80 can be arranged on the base 54 of the installation rail 50, wherein the at least one support rail 78, 79, 80 can project beyond the base 54 in the vertical direction H and extend along the longitudinal direction L. In the vertical direction H, the at least one support rail 78, 79, 80 can be projected beyond by the at least one support projection 55, 57, 58. The base plate 1 and in particular the edge 34 of the base body 2 can rest on the at least one support rail 78, 79, 80 when the base plate 1 is inserted into the installation rail 50.

[0172] Figure 10 shows the embodiment of the Figures 8 and 9in a schematic perspective view and with schematically illustrated connecting lines 15, 16, 17. In the illustrated embodiment, connecting lines 15, 16, 17 running directly to one of the floor panels 1 extend from the respective floor panel 1 between the support projection 55 having the interruptions 77 and the support projection 58 following from the viewpoint of the floor panel 1. A first channel 81 for the connecting lines 15, 16, 17 extends between the support projections 55, 58. The connecting lines 15, 16, 17 can run to a distributor 83, for which the support projections 57, 58 can have an interruption. Lines running between a plurality of distributors 83 or lines 84 running from the distributor 83 to a control system can extend through a further channel 82, wherein the channel 82 can be arranged between the support projections 57, 58.The lines 15, 16, 17 and / or the distributor 83 can be part of a control system of the laying system 70.

[0173] Figures 11 and 12 show a further embodiment of the base plate 1 according to the invention with the installation rail 50 according to the invention, wherein Figure 11 a schematic perspective view and Figure 12 show a schematic sectional view. The same reference numerals are used for elements that correspond in form and / or function to elements of the previous embodiments. For the sake of brevity, only the differences from the previous embodiments are discussed below.

[0174] The floor panel 1 of the illustrated embodiment extends along its longitudinal direction L1, along which the top side 3, the bottom side 4, and one lateral side run. A width direction B1 of the floor panel 1 extends transversely to the longitudinal direction L1 and to the one lateral side 8. A height direction H1 of the floor panel 1 extends transversely to the longitudinal direction L1 and the width direction B1, as well as perpendicular to the top side 3 and pointing from the bottom side 4 to the top side 3.

[0175] The base plate 1 has one lateral side 8 and another lateral side 6, which faces away from the one lateral side 8, and another attachment element 72a. The other attachment element 72a can be arranged at a distance from the one attachment element 72, in particular along the width direction B1. In particular, the other attachment element 72a can be arranged on the other lateral side 6 and, for example, can be formed with it or molded from it.

[0176] The one attachment element 72 and, if provided, optionally also the further attachment element 72a, can extend along the longitudinal direction L1 completely along the base plate 1 and in particular along the respective lateral side 8, 6.

[0177] The attachment elements 72, 72a can be arranged symmetrically, in particular on the lateral sides 8, 6 facing away from each other. This can mean that the projection of one attachment element 72 in the width direction B1 overlaps the other attachment element 72a.

[0178] The base plate 1 can have at least one channel-shaped cable groove 85 that opens away from the top side 3 and runs parallel to the longitudinal direction L1. The base plate 1 can have a plurality of cable grooves 85 that run parallel to one another and / or can be connected to one another by at least one further cable groove or separated from one another by separating webs 86 of the base plate 1. The further cable groove can run essentially along the width direction B1 and interrupt the course of at least one separating web 86.

[0179] In the example of Figures 11 and 12 the at least one separating web 86 separates the at least one cable groove 85 from the receiving recess 21.

[0180] When the floor panel 1 is installed, at least one cable can be arranged in the at least one cable groove 85. The cable can be one of the lines 84 or another cable. If the floor panel 1, together with the cable, is part of the installation system 70, the cable groove 85 can be dimensioned such that the cable at least partially fills the cable groove 85. Transverse to the width direction B1, the cable groove 85 can have a cross-section that is substantially complementary to the cable cross-section.

[0181] If the installation system 70 has a base plate 1 with a plurality of cable grooves 85 and a plurality of cables of different thicknesses, each of the cable grooves 85 can be dimensioned such that only one of the cables substantially fills the respective cable groove 85.

[0182] The receiving recess 21 can widen as it extends away from the upper side 3. For example, the receiving recess 21 can have a clear width W that extends parallel to the upper side 3 and / or perpendicular to the one lateral side 8 and / or the longitudinal direction L1 of the base plate 1. The clear width W can increase in particular in a conical section 87 of the receiving recess 21. The conical section 87 can have an end 88 facing the upper side 3, which is arranged at a distance from the upper side 3.

[0183] The base plate 1 can have a through-opening 89, which adjoins the receiving recess 21 and in particular its conical section 87 in the direction of the upper side 3. A clear width of the through-opening 89 can be smaller than the smallest clear width W of the conical section 87. Alternatively, the smallest clear width of the through-opening 89 can correspond to the clear width of the conical section 87.

[0184] The base plate 1 can have a mounting opening 90 that begins in the top side 3 of the base plate 1 and extends toward the bottom side 4 of the base plate 1. The mounting opening 90 can optionally connect the receiving recess 21 to the top side 3 in a translucent manner through the through opening 89. A clear width of the mounting opening 90 can be larger than the smallest clear width of the receiving recess 21 or the through opening 89.

[0185] The mounting opening 90 can have at least one support 91 for a translucent closure element 92 at its end facing away from the top side 3, to which the through-opening 89 or the receiving recess 21 can be connected. When the floor panel 1 is installed, the translucent closure element 92 can be positioned in the mounting opening 90 on the support 91.

[0186] The mounting opening 90 and the optional through-opening 89, together with the receiving recess 21, can provide an opening that extends continuously from the underside 4 to the top side 3 of the base plate 1.

[0187] The base plate 1 can be formed essentially as a cylinder with a base area defined by the cross-section of the cylinder running along the longitudinal direction L1 and the width direction B1, and can have at least the cable groove 85 and optionally the receiving recess 21, the through-opening 89, and / or the mounting opening 90. The base plate 1 can thus be formed as a continuously cast body. Alternatively, the base plate 1 can be cast using a casting mold.

[0188] Furthermore, at least the mounting opening 90 can be limited in and / or counter to the longitudinal direction L1, wherein at least the mounting opening 90 can be formed by the casting mold or subsequently introduced.

[0189] The installation rail 50 of the embodiment of the Figures 11 and 12 has the longitudinal direction L, wherein at least one side wall 8 extends along the longitudinal direction L.

[0190] The installation rail 50 can have a further counter-attachment element 53a, wherein the further counter-attachment element 53a is arranged at a distance from the one counter-attachment element 53, at least in its mounted state.

[0191] The mounting rail 50 can have one side wall 52 and another side wall 56, between which the receiving opening 51 is arranged. The other side wall 56 can be arranged opposite the side wall 52 having the one counter-attachment element 53 and can have the other counter-attachment element 53a.

[0192] The further side wall 56 can be shorter than the one side wall 52 in a vertical direction H of the installation rail 50 running perpendicular to the floor. In the embodiment of the Figures 11 and 12 However, the side walls 52, 56 of the height direction H have substantially the same length or height.

[0193] The installation rail 50 can have a spacer 94, 94a projecting away from the installation rail 50 on an outer side 93, 93a of one side wall 52 and / or the further side wall 56. A free end 95, 95a of one side wall 52 and / or the further side wall 56 can thus be movable away from the receiving opening 51 when the installation rail 50 is installed. If the one counter-attachment element 53 and / or the further counter-attachment element 53a is arranged closer to the free end 95, 95a than to a fixed end of the respective side wall 52, 56 opposite the free end 95, 95a, the counter-attachment element 53, 53a can be moved away from the receiving opening 51 together with the free end 95, 95a.If the one attachment element 72 and the one counter-attachment element 53, or the further attachment element 72a and the further counter-attachment element 53a, engage with each other in a state in which the floor panel 1 is attached to the installation rail 50, so that the floor panel 1 is possibly positively attached to the installation rail 50, i.e., fastened thereto, this positive connection can be opened by the movement of the respective counter-attachment element 53, 53a. The spacer 94, 94a can rest against another element, such as another installation rail or a normal floor panel, or against a fixed or solid wall, when the installation rail 50 is installed.

[0194] The spacer 94, 94a can have a substantially L-shaped cross-section transverse to the longitudinal direction L of the installation rail 50, so that the spacer 94, 94a, together with the next side wall 52, 56, forms a U-shaped joint 96, 96a that opens opposite to an insertion direction in which the base plate 1 can be inserted into the installation rail 50. The joint 96, 96a can thus open in the height direction H of the installation rail 50.

[0195] An outer side 97, 97a of the spacer 94, 94a, which faces away from the mounting rail 50 and can run parallel to the height direction H and the longitudinal direction L, can have a distance A, Aa from the outer side 93, 93a of the respective adjacent side wall 52, 56. If the counter-attachment element 53, 53a is designed as a projection, the counter-attachment element 53, 53a can have a height transverse to the longitudinal direction L or along the width direction B, which can extend from an inner side of the respective side wall 52, 56 to the free end of the counter-attachment element 53, 53a. If the attachment element 72, 72a is formed as a projection, the attachment element 72, 72a can have a height transverse to the longitudinal direction L1 or along the width direction B1 that can extend from the respective lateral side 8, 6 to the free end of the attachment element 72, 72a. The height can be greater than the distance or correspond to the distance.

[0196] The recessed rail 50 can have a receiving device 98 for captively receiving a lamp 20. Together with the base 54, the receiving device 98 can have a U-shaped cross-section along the longitudinal direction L and the width direction B and open away from the base 54.

[0197] The receiving device 98 can have two opposite side legs 98, 98a, wherein a positioning projection 99, 99a can be arranged at least on the inner side of one of the side legs 98, 98a facing the other side leg 98, 98a.

[0198] The mounting rail 50 can have a positioning device 100 for receiving and, if possible, captively holding at least one cable. Together with the base 54, the positioning device 100 can have a U-shaped cross-section along the longitudinal direction L and the width direction B and open away from the base 54.

[0199] If the installation system 70 comprises the installation rail 50 and a cable, the positioning device 100 can be dimensioned such that the cable substantially fills the positioning device 100 at least in the width direction B. If the installation rail 50 comprises several positioning devices 100 and the installation system 70 comprises several cables of different thicknesses, each of the positioning devices 100 can be dimensioned such that only one of the cables substantially fills the respective positioning device 100 at least in the width direction B.

[0200] The positioning device 100 can be arranged at a distance from one side wall 52 and / or from the other side wall 56. Alternatively, the positioning device 100 can be formed on one side by one side wall 52 or by the other side wall 56.

[0201] The mounting rail 50 can be designed as a cylinder with a base defined by the bottom 54, a side wall 52 with the one counter-attachment element 53, and optionally also by the other elements and fixtures and / or devices. The mounting rail 50 can thus be designed as a continuously cast body.

[0202] Figure 13 shows a further exemplary embodiment of the base plate 1 according to the invention with the installation rail 50 according to the invention in a schematic sectional view. The same reference numerals are used for elements that correspond in form and / or function to elements of the previous exemplary embodiments. For the sake of brevity, only the differences from the previous exemplary embodiments are discussed below.

[0203] The further counter-attachment element 53a can be arranged between the side walls 52, 56. For example, the further counter-attachment element 53a can be arranged closer to one side wall 52 than to the other side wall 56. In the embodiment of the Figure 13 However, the further counter-attachment element 53a is arranged closer to the further side wall 56 than to the one side wall 52.

[0204] For example, the further counter-attachment element 53a can be pressed in its assembled state between the further lateral side 6 and the further side wall 56. For example, when the base plate 1 contacts the one side wall 52, a gap or a gap can remain between the base plate and the further side wall 56, into which the further counter-attachment element 53a is inserted and, for example, pressed in its assembled state.

[0205] The further counter-attachment element 53a can have an attachment wedge 101 or can be formed at least partially as an attachment wedge 101. The attachment wedge 101 can be insertable between the further side wall 56 and a base plate 1 inserted into the installation rail 50. In its mounted state, the attachment wedge 101 can be larger than the gap or the gap, at least in sections, along the width direction B, B1.

[0206] The mounting wedge 101 can have two side surfaces 102, 103 that enclose an angle D of less than 90° between them. The angle D can be an acute angle and, for example, less than 45°, 35°, 25°, 15°, or 5°.

[0207] One of the side surfaces 102, 103 can have the projecting or recessed part of the counter-attachment element 53a. The projecting or recessed part of the counter-attachment element 53a can thus be arranged on one of the side surfaces 102, 103 or formed therefrom.

[0208] The projecting or recessed portion may be arranged closer to a thicker end than to a thinner end of the mounting wedge 101. In the inserted state of the mounting wedge 101, the projecting or recessed portion may face the receiving opening 51.

[0209] The installation rail 50 of the embodiment of the Figure 13 may optionally have at least one spacer 94, 94a.

[0210] In the height direction H, H1, the further side wall 56 can be shorter than the one side wall 52.

[0211] Figure 14shows a further exemplary embodiment of the base plate 1 according to the invention with the installation rail 50 according to the invention in a schematic sectional view. The same reference numerals are used for elements that correspond in form and / or function to elements of the previous exemplary embodiments. For the sake of brevity, only the differences from the previous exemplary embodiments are discussed below.

[0212] The further attachment element 72a can be arranged between the lateral sides 6, 8 facing away from each other. For example, the further attachment element 72a can be arranged centrally between the two lateral sides 6, 8. Furthermore, the further attachment element 72a can be arranged, for example, closer to one lateral side 52 than to the other lateral side 56. In the embodiment of the Figure 14However, the further attachment element 72a is shown as being arranged closer to the further lateral side 6 than to the one lateral side 8.

[0213] The further attachment element 72a can have an opening 104 extending from the top side 3 to the bottom side 4, into the receiving recess 21, or into a further recess that can be formed in the bottom side 4 of the base plate 1. The opening 104 can run along the height direction H1.

[0214] Furthermore, the further attachment element 72a can have a retaining means 105. The retaining means 105 can be inserted into the opening 104. The retaining means 105 can be designed to interact with the further counter-attachment element 53a in a force-fitting or form-fitting manner in order to secure the base plate 1 against unauthorized removal from the installation rail 50.

[0215] For example, the holding means 105 may be a pin with part of a bayonet lock, a rivet or a screw.

[0216] In the example of Figure 14 the receiving recess 21 forms the cable groove 85. The base plate 1 can have at least one further cable groove 85, which is separated from the receiving recess 21 as in the previous embodiments. The base plates of the previous embodiments can also have a cable groove 85 formed by the receiving recess 21 and at least one cable groove 85, which is separated from the receiving recess 21. Alternatively, the at least one cable groove 84 of the base plate 1 of the embodiment of the Figure 14 be formed separately from the receiving recess 21.

[0217] The cable groove 85 formed by the receiving recess 21 can have a substantially constant clear width or width in its course along the longitudinal direction L1 and along the width direction B1.

[0218] The further counter-attachment element 53a can be arranged between the side walls 52, 56 and, for example, centrally between the side walls 52, 56. For example, the further counter-attachment element 53a can be arranged closer to one side wall 52 than to the other side wall 56. In the embodiment of the Figure 14 the further counter-attachment element 53a is arranged closer to the further side wall 56 than to the one side wall 52.

[0219] The further counter-attachment element 53a can be arranged in the receiving recess 21 or in a separate recess which can be formed in the underside 4 of the base plate when the base plate 1 is inserted into the mounting rail 50.

[0220] The further counter-attachment element 53a can protrude in the height direction H from the bottom 54 of the installation rail 50.

[0221] The installation rail 50 of the embodiment of the Figure 14may optionally have at least one spacer 94, 94a.

[0222] Figure 15 illustrates a possible embodiment of a method for providing indications on a floor, in particular a path, in which selected sections of the floor are selectively illuminated from below.

[0223] For example, the floor 100 is depicted as a platform, i.e., a footpath. Of course, the floor 100 can also be the surface of a roadway, such as a street or a parking lot.

[0224] The installation system 70 according to the invention can be used to carry out the method. To provide the instructions, the installation system 70 can selectively backlight selected translucent sections 9-14 of all or selected floor panels 1.

[0225] For example, the laying system 70 in the embodiment of the Figure 11Instructions on where the doors of a train 101 that will soon stop at platform 101 will be located. Train 101 is in the Figure 11 already shown to explain the exemplary procedure. The instructions provided by the routing system 70 can, of course, also be displayed by the routing system 70 when the train 101 stops at the platform.

[0226] For example, translucent sections 9-14 in areas of the floor 100 where the doors of the train 101 are or will be located are backlit. Translucent sections 9-14 in areas where no train doors are expected may not be backlit or may be backlit differently. To guide people to the boarding areas where the doors are expected, translucent sections 9, 11 or 12, 14 of the floor panels 1 of areas that are spaced from the boarding areas arranged adjacent to the train doors and / or adjacent to the boarding areas may be backlit in a substantially arrow-shaped manner.

[0227] The selective backlighting of individual translucent sections of the floor 100 can be adapted to the respective circumstances. Thus, for example, the boarding areas can be adapted to different trains and / or to trains that stop at different locations. The train 101 can communicate the position of the train doors to the routing system 70 directly or indirectly, for example, by the train 101 transmitting the distances between the train doors, and the train 101, the routing system 70, or an external system determining the position of the train 101 on the platform.
