DESCRIPTION OF THE PREFERRED EMBODIMENTS

(12) FIG. 1 shows a device 10 according to the present invention for utilizing a surface 14, such as the surface of a floor, outside wall or roof, for a variable function. In FIG. 1 the distance 11 indicates the width of the surface, wherein the surface extends further perpendicularly of the plane of the drawing. The surface is formed here by a floor 14, but it will be apparent that the device is also suitable for application on any surface, such as the surface of an outside wall or roof, or a ground surface, a dike surface, a sloping surface etc. The device comprises a first functional element 12 consisting of a solar panel formed by a number of sub-elements 12a, 12b, 12c, each situated on respective carriers 15a, 15b, 15c. Carriers 15a, 15b and 15c are formed as tubes extending perpendicularly of the plane of the drawing and disposed rotatably around rotation shafts 16a, 16b, 16c. By means of this rotation a second functional element 13 formed by second functional sub-elements 13a, 13b, 13c can be rotated to the top side, whereby the functional element with which the surface is utilized is changed from functional element 12 to functional element 13a, 13b, 13c, 17a, 17b, 17c, 18a, 18b, 18c, wherein functional element 13a, 13b, 13c, 17a, 17b, 17c, 18a, 18b, 18c is for instance formed by any element from the group of a cold or heat storage element, a water-absorbing, collecting or buffering element, a green element such as a grass cover or moss mat or element with other growth thereon, a fine dust-binding element, an emission-binding and/or neutralizing element such as an NOx-binding and/or neutralizing or SOx-binding and/or neutralizing element, a wind energy generating element. In the shown embodiment the functional elements can extend in an activated mode parallel to each other, and in particular also parallel to floor 14, although it is also possible —for instance when solar panels 12a, 12b, 12c are activated—to place each of these in an optimum orientation relative to the incident sunlight, so that they possibly lie parallel to each other but not necessarily parallel to the surface 14 defined by the floor.

(13) Not shown are blades optionally arranged in or partially around or peripherally of the carrier for the purpose of generating wind energy. The carriers, particularly when they are not being used at least wholly for liquid storage, can also be adapted as energy storage medium, for which purpose they can be embodied as battery. Such batteries can comprise conventional battery acid but can, for instance for safety reasons, also be embodied as salt batteries. The energy storage can however also take place in the form of heat or cold storage.

(14) FIG. 2 shows a second embodiment 20 of the present invention. The second embodiment 20 largely corresponds to the first embodiment 10, except that second carrier 25b is displaceable in the direction of arrow 26. Second carrier 25b does not hereby impede first carrier 25a and third carrier 25c during rotation. In the embodiment 10 of FIG. 1 carriers 15a, 15b, 15care placed at a mutual distance 19 in order to prevent this obstruction, this having the drawback however that unused intermediate spaces 19 are present between the functional sub-elements 15a, 15b, 15c during use. This drawback is obviated by the embodiment 20 of FIG. 2, in which the broken lines 27a, 27b show how the functional sub-elements 21a, 21b, 21c abut each other in an activated mode, wherein second carrier 25b is placed between first carrier 25a and third carrier 25c. Another way of obviating the drawback of the embodiment of FIG. 1 is to make use of carriers with a triangular section, although this results in more limited possibilities for the placing of functional elements.

(15) Carriers 15a, 15b, 15c, 21a, 21b, 21c are preferably embodied as removable and easily replaceable cassettes, and are provided on each of their sides with a functional element. Their rotation points 16a, 16b, 16c, 26a, 26b, 26c are preferably also embodied as throughfeed for electric cabling or, if possible, for heat and/or cold or liquid transfer. In this latter function the device according to the present invention can be coupled to an air-conditioning system optionally already present in a building, on the roof or on the outside wall of which the device according to the present invention is placed.

(16) FIG. 3 shows a subsequent embodiment 30, wherein functional elements 31, 32, 33 are arranged on a belt 34. The functional elements can be translated by moving belt 34, which can be realized by rotating rollers 35, 36, 37, wherein one or more functional elements at a time are brought into an active mode of use. In the shown example the functional elements 32 and 34 are activated, while functional element 33 is in a rest position, wherein it is directed toward the surface.

(17) FIG. 4 shows a subsequent embodiment 40 of the device according to the present invention, wherein functional elements 41, 42, 43, 44 are likewise arranged on a belt 45. In the shown situation the functional element 44 is active. Belt 45 is incorporated in a construction with an upright 48 which is movable. The angle at which the portion of belt 45 situated between outer ends 46 and 47 of the uprights of the device lies relative to the surface can be changed by sliding upright 48 in the direction of arrow 49. An optimum angle for the active functional element can in this way be adjusted.

(18) FIG. 5 shows a schematic cross-sectional view of a carrier 50 for use in a device according to the present invention. The carrier is provided with functional elements 51, 54, 55, 56, wherein functional element 51 is embodied as a liquid-permeable cloth. Liquid such as precipitation can be collected in carrier 50 by directing the liquid-permeable cloth 51 to a side from which precipitation can fall. The carrier is embodied for this purpose as an at least partially hollow tube in which a number of elements 53 are arranged for the purpose of holding the liquid. Overflows 52 are also arranged which serve the purpose of keeping the liquid level below a predetermined maximum.

(19) FIG. 6 shows a schematic view of a section of an alternative embodiment 60 of the present invention. The device is provided with three carriers 61, 62, 63, of which at least the sides 61a, 62a, 63a are adapted to allow through rainwater. Sides 61b, 62b, 63b can be adapted for any other functionality. Carriers 62 and 63 are shown in a mode suitable for collecting rainwater, while carrier 61 is shown in a mode suitable for relinquishing rainwater. It is possible to opt to collect the rainwater with the purpose of recovering the water, but it is also possible to have collection take place with the intention of preventing overload of the water drainage or a sewer system.

(20) FIG. 7 shows a schematic view of a fifth embodiment 70 of a device according to the present invention. In this embodiment a storage unit 71 houses a plurality of carriers, of which carriers 72-78 are shown in an active mode, wherein they cover surface 79. The carriers can be placed in an active mode by means of translation parallel to surface 79 or be interchanged with other carriers (not shown) incorporated in the storage unit. Carriers 72-78 can also be placed in their active mode above a functional element which is arranged on surface 79 and which can be activated by incorporating carriers 72-78 in the storage unit.

(21) FIG. 8 shows a schematic view of a following embodiment 80, wherein the storage unit comprises a plurality of functional elements 81, 82 which can be arranged on the surface in accordance with a jukebox or carrousel principle. Many variations are possible in addition to the embodiments shown, all being deemed to fall within the scope of protection of the following claims.

(22) FIG. 9 shows a schematic view of a building 90 around which is arranged a carrier frame 91 on which the device according to the present invention is arranged.

(23) FIGS. 10a-d show a part of building 90 on which a carrier structure is arranged for containing the device for utilizing the surface according to the present invention. Shown is how a frame 92 is arranged on which are situated rotation shafts 93 which hold carriers 94 formed by cassettes for rotation about shafts 93.
