Description

In order to achieve light extraction from edge surface areas which guide the light under conditions of total internal reflection, it may, for example, be provided that these or other edge surface areas have a structure that disrupts total internal reflection. For example, such an edge surface area may be designed to scatter light either in sections or across its entire surface, e.g. by being matt or satin-finished. The lighting device may be powered by a power source arranged within the spacer as a further functional element, for example by at least one battery, or via an external power connection. Provision may be made to control the lighting device by means of a control device integrated into the spacer, e.g. in response to an external signal or a measured value detected by a sensor. A preferred embodiment provides that a lighting device comprises a plurality of individual light sources, in particular a plurality of individual LEDs, in particular wherein the light sources / LEDs are arranged side by side on a circuit board strip, the light sources being arranged circumferentially around an element penetrating the spacer. In a preferred embodiment, such a penetrating element may, for example, be formed by the waste water pipe and / or the flush water pipe of a toilet bowl. This embodiment has the advantage that there is no shading of the light caused by the penetrating element, as the light is effectively emitted into the spacer from the element itself. In a preferred further embodiment, the light sources are arranged on a ring emitting light radially outwards, which is situated in a recess in the spacer penetrated by the element or on the penetrating element itself. Another possible design may provide for the light sources, in particular those arranged side by side on a circuit board strip, to be seated in a groove arranged in the spacer, which groove is routed in the spacer, at least partially around at least one recessed area, in particular a single recessed area, which is provided in the spacer for the passage of fastening elements and / or pipework elements through the spacer. Preferably, the groove is formed from one of the mounting surfaces of the spacer towards the other mounting surface. A circuit board strip is preferably positioned in the groove such that the light sources / LEDs shine through outwardfacing edge surface areas of the spacer. The groove preferably has a depth that is greater than or equal to the width of the circuit board strip and less than the thickness of the spacer. Preferably, the plurality of light sources is connected by means of a cable to another functional element, in particular a power source and / or control device, with the cable preferably guided in a groove or channel in the material of the spacer. For example, a functional element may be configured as a signal generator for producing an acoustic or optical signal, in particular for generating a sequence of tones or voice output. For example, a signal perceptible to the user may be generated in this way, e.g. depending on an operating state of the object; for instance, in the case of a toilet bowl, when a user sits down and / or stands up and a sensor detects this. For example, a functional element may be provided by a sensor for measuring an operational state of the object, in particular wherein the sensor is configured as a motion detector or force sensor or vibration sensor or optical sensor (e.g. a light barrier). For example, the sensor can be used to detect the use of an object, such as a toilet bowl, when a user is sitting on it and a sensor—for example, a force sensor—measures the resulting force load. For example, it may be provided that a sensor, preferably an optical sensor, is used to detect the movement of a part of the object, in particular the opening and / or closing of a toilet seat, and, depending on this, to trigger an action via another functional element, e.g. via the signal generator. A functional element may also be constituted by a signal input, in particular for triggering an action of another functional element in response to a signal received from an external source. Such a signal received from an external source may, for example, originate from a home automation system and may be triggered, for example, when a user enters a room containing the object. The signal may, for example, originate from a motion detector in the home automation system that is external to the spacer. The signal may, for example, trigger a function of the lighting device and / or the signal generator. The signal input may, for example, be wired or implemented using radio technology. A functional element may also be configured as a control device for controlling another functional element, in particular a lighting device or a signal generator. Preferably, the control device is configured to carry out the control operation in response to a signal from another functional element, e.g. in response to a received measurement value from a sensor, in particular a sensor mentioned above, or a received signal. For example, the control device may receive the force signal from a force sensor or the signal from an optical or other sensor and, depending on this, control the lighting device and / or the signal generator. For example, a functional element may also be configured to comprise at least one energy source, in particular a battery or a rechargeable battery, for supplying power to at least one other functional element. The aforementioned functional elements, listed by way of example, may be implemented individually and in any combination on or within the spacer. There may be wired and / or wireless electrical connections between different functional elements, enabling them to exchange information or signals with one another. Cables for connecting two or more functional elements may be routed through grooves and / or channels in the material of the spacer, which run between the connected functional elements. In particular, it is envisaged to combine at least one lighting device and / or a signal generator with a sensor and a control device, in particular also with a power source provided in or on the spacer or an external power source, which control device controls these depending on the sensor’s measured value. A signal input may additionally be provided. A particularly preferred embodiment provides for the spacer to be formed as a plate with a U-shaped cross-section, in particular as a plate with a U-shaped cross-section perpendicular to the direction of spacing between the object and the fixing structure. Preferably, the U-shaped plate has a base which, when installed as intended, is situated at the top of the arrangement, with a downward-extending leg having a free end arranged on each side of the base; preferably, the legs taper towards their free ends and / or are inclined towards one another, in particular, a single recess is formed between the legs and the base, through which fastening elements and / or pipework elements of the object are passed. It is further preferred that a groove for accommodating a functional element, in particular for accommodating a lighting device, preferably for accommodating a circuit board strip comprising light sources, be provided along the course of the legs, in particular also extending along the course of the base, preferably with the groove being spaced further from the outward-facing edge surface areas of the legs than from the edge surface areas of the legs facing inwards towards the single recess. The position of the groove may be selected such that fastening forces act through the spacer in the area of the legs, laterally on the outside next to the groove. It is further preferably provided here that a power source for supplying the lighting device is arranged within the single recess, in particular on the inner side of one of the legs. The invention offers the advantage of enabling object arrangements according to the invention to be produced, either originally or retrospectively, from a known object arrangement of the prior art, by inserting, for the purpose of securing an object—in particular a sanitary object—to a fixing structure, a spacer made of a transparent material, in particular an uncoloured transparent material, between the mounting surface of the object and the fixing structure. For this purpose, a plate made of a transparent material, in particular an uncoloured transparent material, preferably with clearly transparent edge areas, is used as a spacer when securing the object, in particular a sanitary object, to a fixing structure, in particular to achieve a visual effect of the object appearing to float in front of the fixing structure. The invention is explained in more detail with reference to the figures. Figures 1A and 1B show, in two different views, a first embodiment of the invention using a toilet bowl as object 1, which is secured on a wall as fixing structure 2 by means of a spacer 3 made of a transparent plastic, e.g. PMMA / acrylic glass. Both the fixing screws / threaded rods and the water supply and waste water pipes pass through the spacer 3; in Figure 1B, this is shown with a dotted line only for the waste water pipe 4. The spacer 3 has a typical thickness within the preferred range of 10 mm to 35 mm, in particular 25 mm, whereby its edge surface areas 3a, which form the visible outer periphery of the spacer 3, are preferably made to be clear and transparent, e.g. by subsequently polishing the edge surface areas 3a produced during a cutting process. In this embodiment, it can be seen that the edge surface areas 3a are oriented perpendicular to the surface of the wall 2 on which the toilet bowl 1 is secured, and also to the opposing contact surfaces of the spacer 3, across the entire circumferential periphery of the spacer 3. The spacer 3 has a uniform cross-section throughout its entire thickness, whereby the contour of the cross-section of the spacer 3 is identical in shape to, or scaled down by a factor relative to, the contour of the cross-section of the toilet bowl 1 in plane E, in which the mounting surface 1a of the toilet bowl lies, or in a plane E1 explained below; or the contours of both the spacer 3 and the toilet bowl 1a lie at least substantially on top of one another. By securing the toilet bowl 1 indirectly via the spacer 3 made of transparent material, preferably with clear, transparent edge areas, and by adapting the outer cross-section of the spacer 3 to the cross-section of the toilet bowl 1 in the plane of its mounting surface 1a or the plane E1 described below, a visual impression is created, in which the toilet bowl appears to float in front of the wall 2, whilst being securely secured to the wall 2 and, in particular, featuring all necessary water connections. In contrast to Figures 1A and 1B, Figures 2A and 2B show, in the same views, a second embodiment in which the spacer 3 is designed such that its cross-section tapers on all sides from the contact surface against which the toilet bowl 1 rests towards the contact surface against which the wall 2 rests, tapers linearly in this example, so that all edge surface areas 3a are inclined towards the wall 2; in particular, they are no longer oriented perpendicular to the wall 2. This ensures that, when viewed by a user standing in front of the toilet bowl 1, the edge surface areas 3a are at least partially—or, depending on the angle of inclination, completely—concealed behind the edges 1b of the toilet bowl 1, which delimit the mounting surface 1a in plane E. In this embodiment, despite the tapering of the spacer 3, full-surface support of the mounting surface 1a in plane E is achieved, because the spacer 3 preferably has the same cross-section there as the toilet bowl 1. Figures 3A and 3B show, in the same views, a third embodiment in which the tapering of the adapter plate 3 is provided only in the upper edge area 3a, which a user looks directly at from above. The other edge surface areas 3a are oriented perpendicular to the surface of the wall 2 in the sectional views shown. Figure 4 shows a further variant, in which the upper edge surface area 3a of the spacer 3 comprises a groove 3b, in particular, in which the upper edge surface area 3a is designed to slope downwards towards the wall 2 in a first partial surface area, which is closer to the toilet bowl 1, and in particular slopes linearly, whilst in a second partial surface area, which is closer to the wall 2 than the first partial surface area, it features a channel 3b. The channel 3b makes it easier to collect and clean away any dirt or splash water that accumulates. The other edge surface areas 3a may, for example, be designed as shown in Figures 2b or 3b. Figure 5 shows a further variant in which the upper edge area 3a features a channel 3b across its entire thickness extending between the toilet bowl 1 and wall 2. Here too, the other edge areas 3a may, for example, be configured as shown in Figures 2b or 3b. In this embodiment, the channel 3b acts as a concave lens for light emerging from the spacer—such as that originating from fixing elements or pipework—so that these elements, insofar as they are visible, appear smaller than they actually are. This significantly reduces the visual prominence of these elements. Preferably, the two contact surfaces of the spacer 3 are shaped to correspond to the crosssection of the toilet bowl in plane E. In this design, the spacer 3 is also tapered to a maximum degree between the two contact surfaces. Figure 6A shows a further embodiment in which the upper edge surface area 3a is lowered in height below the upper edge 1b of the toilet bowl 1 in plane E, with this edge surface area 3a being oriented perpendicular to the fixing surface of the wall 2. This also causes the upper edge surface area 3a to be out of a user’s immediate field of view, or rather below this upper edge of the toilet bowl 1. Lowering the upper edge surface area 3a below the upper edge 1b corresponds to the edge surface area being set back inwards behind the edge 1b or contour. Here too, the other edge surface areas 3a may, for example, be configured as shown in Figures 2b or 3b. According to Figure 6B, however, the lateral edge surface areas 3a are also configured to recede inwards behind the contour of the toilet bowl, in the same way as the upper edge surface area 3a. Preferably, the amount by which the upper edge surface area 3a is recessed below the upper edge 1b of the toilet bowl 1, or the distance of the lateral edge surface areas from the contour, in one possible embodiment, corresponds to the thickness of the spacer 3, or in another possible embodiment, to 50% to 75% of the thickness, in particular 60% of the thickness of the spacer 3. Figure 7 illustrates that, in the case of an object 1 manufactured in accordance with specific production techniques—such as the toilet bowl 1 shown with rounded edges 1b at the transition to the mounting surface 1a, which is depicted in a highly exaggerated manner in Figure 7—it is advisable to design the cross-section or the contour of the cross-section of the spacer 3, which is not shown here, particularly at its contact surface facing the object 1 or the fixing structure 2, not to be precisely adapted to the cross-section of the object 1 at the location of plane E of the mounting surface 1a, but rather to the cross-section of the object 1 at a distance in front of the mounting surface 1a, in this case plane E1, whereby this plane E1 is at a distance from plane E which is preferably less than 15 mm, more preferably less than 10 mm, and most preferably less than 5 mm. Plane E1 should preferably be at a minimum distance from plane E such that plane E1 lies outside a manufacturing-related rounding. The use of plane E or plane E1, as described here, to define the contour is preferably employed in all possible embodiments of the invention. Figure 8A shows an embodiment in which a lighting device 5 is integrated into the spacer 3, for example arranged in a recess in the lower edge surface region 3a. This allows light 6 to be coupled into the spacer 3, which passes through the spacer 3 and propagates within it, at least in some regions, according to the principle of total internal reflection. The light 6 can, for example, emerge from the edge surface areas on all sides. Figure 8B shows an alternative embodiment in which the lighting device 5 comprises a plurality of light sources 5a, in particular LEDs, arranged in a ringshaped configuration around the flushing water pipe 4 and / or the waste water pipe 4 of the toilet bowl 1 in the circumferential direction. As a result, the light 6 emanates from the respective pipe, so that no shadowing effect occurs through it. The annular arrangement of light sources 5a may be formed by a ring with light sources 5a emitting radially outwards, which is slid onto the respective pipe 4 and supported by it, or which is secured to or within the edge of the recess in the spacer 3 through which the respective pipe passes. The ring may, for example, be formed by a ring-shaped, curved circuit board strip with light sources. Figure 9 shows a further embodiment in which a signal generator 7, in this case preferably a sound generator 7, is arranged within the spacer 3. This can, for example, be activated in response to a measured value recorded by the sensor 8. For example, at least one sound or a voice message can be played when the sensor 8 indicates a monitored operating state, such as a user sitting down or standing up. The control device for activating the sound generator 7 in response to the measured value from the sensor 8 may be integrated into the sound generator 7 or arranged externally to it within the spacer 3. Figure 10 shows a structurally preferred embodiment of the spacer 3, in which the latter is designed as a plate with a U-shaped cross-section, in particular as a plate with a U-shaped cross-section perpendicular to the direction of the spacing between the object and the fixing structure. Object 1 and fixing structure 2 are not shown here. Here, the spacer 3 has a base 3c, which, when installed as intended, is positioned at the top of the arrangement; on each side of this base there is a downwardextending leg 3d with a free end, preferably such that the legs 3d taper towards their free - in this case lower - ends and / or are inclined towards one another. In this embodiment, only a single recess 3e is formed between the legs 3d and the base 3c, through which fastening elements 13 and / or pipework elements 4 of the object 1 are passed, which are shown here as dotted lines. Figure 10 further illustrates, in the top view, that the edge surfaces 3a of the spacer 3 are all located on the inside relative to the contour K of a toilet bowl in the region of its contact surface / mounting surface, in particular the contour in the plane E or E1, which is shown here as a dotted line on the outside of the spacer 3. Alternatively, it may also be provided that the outer edge surface region 3a follows the same contour as contour K. According to the invention, however, the crosssection of the spacer 3 does not extend beyond contour K at any point. The embodiment shown here provides for a groove 11, designed to accommodate a functional element—in particular, here to accommodate a lighting device 5, preferably to accomodate a circuit board strip 5b comprising light sources 5a—to run along the course of the legs 3d, and in particular also along the course of the base 3c. In this context, the groove 11 is preferably spaced further from the outward-facing edge surface areas 3a of the legs 3d than from the edge surface areas 3a of the legs 3d that face inwards towards the single recess 3e. The lower part of Figure 10 shows a detailed view of the groove 11 with the circuit board strip 5b and the light sources / LEDs carried by it, the light emission direction of which is directed outwards. In this embodiment, it may be preferable for all, or at least the outward-facing edge surface areas 3, to be designed to diffuse light, e.g. by matting or satin-finishing the surface. However, the edge surface areas 3a may also be polished. A power source 12 for supplying the lighting device 5 is arranged in the single recess 3e, in particular on the inner side of one of the legs 3d, and is connected to the lighting device 5 via cables. Alternatively, a power source may also be arranged externally to the spacer 3. The depiction of the power source 12 here therefore does not limit the U-shaped design of the spacer 3. Due to the U-shaped design, the single recess 3e is open at the bottom, which allows access to the recess 3e so that, if necessary, further required elements— such as the functional elements mentioned above—can be arranged between object 1 and the fixing structure 2. The specific internal configuration of the edge surfaces 3a, which delimit the single recess 3e, is irrelevant to the invention. The specific embodiment shown here is therefore not to be understood as limiting the invention.
