Definitions

• the present invention relates to a room divider for the flat design and subdivision of rooms, in particular office rooms, exhibition and living rooms, according to the preamble of claim 1, and a room divider system comprising a plurality of such room dividers.
• the known room dividers are mostly room dividers made of solid materials that stand on the floor and are screwed into their respective places or held in an upright position via legs. Room dividers are used to achieve a subdivision of the room into several sub-rooms in open-plan offices, in exhibition rooms, especially at trade fairs, and also in large living rooms, which are optically, but if possible also acoustically separated.
• a disadvantage of such room dividers is that they can only be produced at considerable costs, and are relatively difficult to assemble and disassemble or move. In addition, the mostly bare surfaces of the room dividers create an uncomfortable light atmosphere.
• room dividers such as Spanish walls and screens, which are made of stretched fabrics, for example, and are used for stage design. Although these room dividers are very light, their use in busy large rooms is not practical because they do not provide adequate sound absorption.
• the present invention is therefore based on the object of creating a room divider for the planar design and subdivision of rooms, in particular office rooms, exhibition and living rooms, which is easy to assemble and disassemble or can be moved, which blocks noise from outside as effectively as possible and with whose help also provides good room lighting.
• This object is solved by the features of claim 1.
• the room divider has at least two membranes that are attached to at least a first upper attachment point in the room or to the ceiling, and that the membranes are attached to at least two lower attachment points below the at least one first attachment point or the ceiling, and that Each membrane provides an outer wall surface on both sides of the room divider, it is ensured that the room divider has little weight and is therefore easy to assemble, disassemble and move, but that noises and conversations from nearby areas separated by the room divider are largely absorbed and also creates a pleasant sense of light.
• a particularly versatile application of the space divider according to the invention is achieved in that the membranes are connected at several points with connecting rods or ropes which are attached to the ceiling.
• the membranes are fastened to a supporting structure, preferably a frame structure, on which the membranes are stretched.
• the frame construction advantageously has additional rods, rods, ropes or small support frames, on which the membranes are at least partially fixed, so that the load on the individual fastening points decreases.
• a renewed three-dimensional deformation of the membranes at determinable points or lines within the spanned areas between the fastening points results in light scattering in many different directions.
• the membranes are formed in two or more layers, at least one layer consisting of sound-absorbing material.
• the membranes are advantageously designed to reflect light.
• the membranes are at least partially translucent and light elements are arranged on the supporting structure.
• At least two room dividers are connected to one another in a fixed or articulated manner to form a room divider system, so that any geometrical shapes of the room division are possible.
• the room dividers are connected to form a closed room, which significantly reduces background noise.
• the closed space advantageously has a base part and rollers arranged thereon, so that it can be moved as a mobile box with little effort.
• 1-3 each show a cross section through an embodiment of the room divider according to the invention
• FIG. 4a shows a cross section through a further embodiment of the room divider according to the invention with a light element
• 4b shows a cross section through a further embodiment of the room divider according to the invention with integrated storage
• 5 shows a cross section through a section of a further embodiment of the room divider according to the invention
• FIG. 6 shows a perspective view of a room divider system comprising a plurality of room dividers which are movably connected to one another;
• FIG. 7 shows a schematic cross section through an office container, formed from room dividers according to the invention.
• the room divider 1 uses two membranes 2, which are either attached directly to the ceiling or are suspended on a standing, load-bearing structure 13, as shown in FIG. 1.
• the membranes are used for sound absorption and light reflection or for light transmission.
• the term membrane is intended to encompass all webs of suitable known, at least partially sound-absorbing materials and fabrics, fabrics, foils, coated fabrics, etc. Some preferred examples are provided in the description of Figures 8 a-e.
• the two membranes 2 on both sides of the wall divider 1 are stretched relatively tightly on the supporting structure 13 between fastening points 15.
• the load-bearing structure 13 can consist, for example, of a support frame 8, additional rods, rods, ropes or small support frames within the large frame structure to which the membranes 2 can additionally be attached being advantageous.
• the room dividers 1 as such can either be attached to walls to prevent them from falling over, or have legs (not shown) with which they stand stably on the ground. It is also possible to create a stable room divider system 3 simply by angular connection with other room dividers, as shown in FIG. 6.
• each membrane 2 can be deformed three-dimensionally again by suitable bulge arrangements 16, as shown in FIG. 2.
• suitable bulge arrangements 16 For example, rounded pressure surfaces, which are connected to the frame structure 13 via connecting struts arranged perpendicular to the load-bearing structure 13, could push the membranes 2 outwards between the fastening points 15.
• the use of springs also serves this purpose. The membrane should not be too tight.
• the shape of the bulges of the membranes is not limited to the described embodiments, but many other geometrical arrangements are just as conceivable as a combination of different arrangements on the two wall surfaces of the room divider.
• an additional insulating layer 6, for example made of felt, can be arranged between the two membranes 2 for better sound absorption and to prevent the incidence of light, which can consist of suitable sound and / or light-retaining material , As well it is conceivable to fill sand, plastic elements, translucent glass elements or the like between the two membranes 2. Then spacers are required at short intervals, as will be explained again in detail in relation to FIGS. 8a-e.
• FIG. 6 shows a room divider system 3 comprising a plurality of room dividers 1, which are connected at an angle to one another and do not need any legs.
• the room dividers are equipped with rollers so that the entire room divider system 3 can be moved anywhere in the room. If the individual room dividers 1 are movably connected to one another, the flexibility of setting up and the geometric spatial division generated becomes even greater.
• FIG. 7 shows a section through a preferred room divider system 3.
• the individual room dividers 1 are connected to form a rectangular or circular closed room 4 which can be used, for example, as an office container. If you connect the individual room dividers 1 to a floor part 5, which stands on rollers 9, a complete office space can be moved easily since its walls have extremely little weight. In order to achieve an even better isolation from the surroundings, an additional cover, for example made of membranes, can be provided on the upper edge of the room divider 1.
• the membrane 2 consists of a fleece composite 21, in which a fleece 22 is connected, for example sewn, to a fabric 23.
• a fleece 22 is connected, for example sewn, to a fabric 23.
• felts, foams or other light materials can also be used. The lightness of the material allows all possible forms of the membrane.
• FIG. 8b shows a membrane made of two such fleece composites 21, which are sewn together as individual webs at a certain distance via connecting threads 24, air being located in the space 25 between the webs.
• Such a membrane is still very light, but advantageously already allows a clear sound absorption.
• FIG. 8c shows an embodiment of a membrane similar to that in FIG. 8b, with the difference that an additional absorbing layer 26, for example a felt insert, is located in the intermediate space 25.
• the connecting threads 24 can then be dispensed with because the nonwoven composites 21 are connected directly to the felt 26, for example sewn on.
• sand 27 or another coarse-grained material can also be filled in between the outer fleece composites 21, as shown in FIG. 8d, the connection between the fleece composites 21 then having to be made, for example, by very strongly anchored, thick threads 30, to withstand the weight of the filled material.
• thicker webs such as z-shaped ones
• the outer layer should be light-reflecting in order to provide ideal illumination of the room.
• the membranes are formed from translucent material, at least in some areas.
• fluoropolymers offer a light transmission of up to 95% in the visible range, combined with a low refractive index. The direct light rays are optimally converted into scattered light on the structure of the fabric. The result is a very evenly distributed scattered light with little shadow formation.
• a membrane can consist, for example, of two transparent material webs 28, which are connected as in FIG. 8d, and between which small transparent glass or plastic elements 29 are filled, as shown in FIG. 8e ,
• the present invention is not limited to the exemplary embodiments shown. Other combinations of the above and other suitable materials that have the required properties can be used here.
• the properties of the membranes can also be changed by coatings, for example by metallization.
