Description

[0001] The invention relates to a partition wall element for a workplace, comprising a panel designed as a sound absorber and a lighting device, wherein the lighting device is designed to illuminate the workplace, wherein the panel has an upper side on which the lighting device is arranged.

[0002] Partition wall elements are used to spatially separate workspaces. Partition wall elements are used, among other things, to improve workplace acoustics, for example, in open-plan offices and meeting rooms. Depending on the dimensions of the room and its furnishings, this can lead to unfavorable distributions of direct and reflected sound, as well as unfavorable reverberation behavior. This can result, for example, in poor speech intelligibility.

[0003] From US 3,592,288 a room acoustic element is known which is designed as a sandwich and has an elastic core.

[0004] When partition wall elements are used for workstations, the illumination of the workstation by existing installed room lighting is often disadvantageous, as it often results in unwanted reflections on workstation screens or insufficient illumination. This is also due to the fact that the arrangement of the installed room lighting often cannot be changed without considerable effort.

[0005] The invention is based on the object of providing a partition wall element for a workplace with integrated lighting and with sound-absorbing properties, which has improved usage properties.

[0006] This object is achieved by the features of claim 1. The subclaims refer to advantageous embodiments.

[0007] The partition wall element according to the invention for a workplace comprises a panel designed as a sound absorber and a lighting device, wherein the lighting device is designed to illuminate the workplace, wherein the panel has a top side on which the lighting device is arranged. The partition wall element spatially demarcates the workplace on one side from an adjacent area. The panel serves as a visual screen due to its physical extension and as sound insulation due to its sound-absorbing properties. As a result, disruptive noises generated in the adjacent area can be largely absorbed so that they do not reach the workplace or only reach it in a muffled manner. Furthermore, noises generated at the workplace, such as conversations, can also be absorbed or muffled so that they do not reach adjacent areas or at least only reach it in a muffled manner.The workstation may, in particular, include a desk with a tabletop height between 60 cm and 130 cm. The workstation may be designed as a computer workstation and include one or more monitors.

[0008] The plate can have a first main side and a second main side. The plate is dimensioned by a plate length, a plate width, and a plate thickness. The first and second main sides are preferably opposite flat sides and are preferably substantially rectangular. The distance between the first main side and the second main side can correspond to the plate thickness, whereby the plate thickness can be smaller than the plate length and / or the plate width.

[0009] The panel thickness can be between 3 cm and 20 cm. Preferably, the panel thickness is between 4 cm and 10 cm. The panel thickness is particularly preferably 5 cm.

[0010] The panel width can be between 60 cm and 150 cm. Preferably, the panel width is between 70 cm and 120 cm. The panel width is particularly preferred.

[0011] The panel length can be between 100 cm and 220 cm. Preferably, the panel length is between 120 cm and 180 cm. The panel length is particularly preferably 150 cm.

[0012] Furthermore, the panel can have a top side and a bottom side. The partition wall element is preferably arranged in a room with a floor and a ceiling, wherein the top side of the panel is assigned to the ceiling of the room and the bottom side of the panel is assigned to the floor of the room. The partition wall element can be arranged on a floor such that the partition wall element projects essentially perpendicularly from the floor. The partition wall element extends from the floor towards the ceiling. The partition wall element can have feet, via which the partition wall element can be placed on the floor. This allows the panel to be spaced from the floor. The top side of the panel can extend along a first edge of the panel from the first main side to the second main side. The bottom side can extend along a second edge of the panel opposite the first edge from the first main side to the second main side.

[0013] The panel can comprise at least one central layer, which is preferably made of an acoustically dampening yet dimensionally stable material. Such a material can, for example, comprise coconut fibers. The coconut fibers can form a coconut mat. The coconut fibers can be coated. The fibers are preferably coated with natural rubber. Each of these measures can improve the sound-absorbing properties of the partition wall element.

[0014] The panel can further comprise at least one intermediate layer, wherein the intermediate layer is a material equipped with hollow chambers. The material comprises a support structure in which hollow chambers are enclosed. The support structure serves to provide mechanical stability, while the hollow chambers enclosed by the support structure have sound-absorbing properties and reduce the weight of the intermediate layer. Such a material can, for example, have a honeycomb structure. The walls of the honeycomb structure form the support structure and enclose honeycomb-shaped hollow chambers. The honeycomb structure is particularly advantageous with regard to the mechanical stability of the intermediate layer. One embodiment of an intermediate layer with a honeycomb structure is honeycomb cardboard. In another embodiment, the intermediate layer is made of plastic and provided with a honeycomb structure.In principle, the use of metallic materials for the honeycomb structure is also conceivable. The hollow chambers can also be wave-shaped or tubular.

[0015] The material of the intermediate layer, particularly the walls of the honeycomb structure, can be perforated to improve sound permeability. The perforations can have dimensions smaller than 10 mm. The dimensions are preferably smaller than 3 mm, particularly preferably smaller than 0.5 mm. As a result, the intermediate layer forms a sound-absorbing labyrinth, so that sound waves impinging on the intermediate layer can penetrate the intermediate layer, but only a small proportion of the absorbed sound waves leave the intermediate layer again. This can further improve the sound-absorbing properties of the panel.

[0016] It is also conceivable to form the intermediate layer from a rigid foam, in particular from a rigid plastic foam. Such an intermediate layer is lightweight and dimensionally stable. If the intermediate layer is provided with cover layers, a particularly dimensionally stable sandwich component is produced. According to a further embodiment, the intermediate layer can be formed from a fiber composite material. The fiber composite material can comprise pressed natural or polyester fibers.

[0017] The plate preferably has two intermediate layers, with the intermediate layers being arranged on either side of the central layer. It is particularly preferred if the intermediate layers are directly adjacent to the central layer.

[0018] The panel may further comprise at least one cover layer, preferably made of a textile material. In particular, the cover layer may comprise natural fibers. Materials made of wool or cotton, such as wool felt or stage felt, are particularly conceivable in this context. The cover layer improves the sound-absorbing properties of the panel.

[0019] The panel preferably has two cover layers, with the cover layers arranged on both sides of the central layer. It is particularly preferred if the cover layers are arranged on a side of the intermediate layer facing away from the central layer. The cover layers are thus the outer layers of the panel of the partition wall element. Furthermore, the panel can have multiple cover layers. The cover layers preferably cover the main sides.

[0020] The lighting device can comprise a holder and a light head, the holder connecting the light head to the plate. The holder is preferably elongated, in particular rod-shaped. A first end of the holder projects into the plate, while a second end of the holder, opposite the first end, projects from the top side of the plate. The light head is preferably arranged at the second end of the holder. The holder preferably passes through the top side of the plate so that the holder is connected to the plate at its first end. The holder is preferably hollow so that the electrical connection of the light head can be led through the holder into the plate.

[0021] Preferably, the lamp head is connected to the mount so that it can rotate around a longitudinal axis of the mount. This allows the lamp head to be aligned so that the work area to be illuminated is particularly well illuminated.

[0022] In a preferred embodiment, the holder can comprise a telescopically extendable rod whose links can be moved and fixed in guides. This allows the length of the rod to be varied in order to adjust the distance between the plate and the light head. Alternatively, the holder can be designed as a rod of constant length whose position can be moved along its longitudinal axis relative to the plate. For this purpose, the holder can be at least partially recessed into the plate. This allows the distance between the plate and the light head to be adjusted despite the constant length of the rod. The distance between the plate and the light head can be up to 150 cm. Preferably, the distance between the plate and the light head is up to 100 cm. Particularly preferably, the distance between the plate and the light head is 50 cm. This can further improve the illumination of the workplace.

[0023] The luminaire head can comprise at least one direct light source and / or at least one indirect light source. With a direct light source, a luminous flux from the direct light source enters the room to be illuminated, in particular the work area, without deflection. With an indirect light source, the luminous flux enters the room to be illuminated only via reflectors that deflect it. Indirect light sources can, in particular, create a luminance distribution in the room to be illuminated that is perceived as pleasant, producing glare-free illumination.

[0024] The partition wall element can have a support base. This allows the partition wall element to be freely set up in rooms. The support base is preferably arranged on the underside of the panel. The support base can be ring-shaped or disc-shaped. The support base is preferably elongated. The support base preferably has a set-up position and a storage position. In the set-up position, a longitudinal axis of the elongated support base is aligned perpendicular to one of the main sides. In the set-up position, the partition wall element can be arranged particularly stably. In the storage position, the longitudinal axis of the support base is aligned parallel to an edge of the underside, in particular the second edge. In the storage position, the partition wall element can be stored or transported in a particularly space-saving manner.

[0025] The support foot is preferably arranged so as to be rotatable and can be transferred from the set-up position to the storage position and / or from the storage position to the set-up position by rotating the support foot. The partition wall element preferably comprises a plurality of support feet. Particularly preferably, the partition wall element comprises two support feet. A first support foot is assigned to a first end of the underside, and a second support foot is assigned to a second end of the underside opposite the first end. The first support foot is arranged at a distance from the second support foot, thereby improving the stability of the partition wall element in the set-up position.

[0026] The partition element may comprise a power connection for supplying power to the partition element. The power connection for the power supply is electrically connectable to a power source and serves to supply power to the partition element, in particular to the lighting device.

[0027] Preferably, the power connection for the power supply is located on the underside of the partition element. The partition element can also include a power connection for power consumption. The power connection for power consumption serves to connect one or more electrical devices, e.g., chargers, monitors, computers, or printers.

[0028] The power connection for power extraction is preferably assigned to the underside or one of the main sides of the partition element. The partition element preferably has more than one power connection for power extraction. Preferably, a first power connection for power extraction is arranged on the underside of the partition element, and a second power connection for power extraction is arranged on one of the main sides of the partition element.

[0029] Preferably, the second power connection for power extraction is arranged at a distance of between 60 cm and 160 cm from the underside on one of the main sides. In particular, the second power connection for power extraction can be arranged at a distance from the underside on one of the main sides that corresponds to the height of a desk. The power connection for supplying power to the partition element can be connected to a power connection for power extraction of another partition element in order to connect the partition element and the other partition element in series.

[0030] The power connection for the power supply and / or the power connection for the power consumption can be designed as a plug-in connector. The power connection for the power supply is preferably designed as a plug or a socket. In particular, the plug can be designed as a safety plug or the socket as a power socket. The power connection for the power consumption is preferably designed as a socket, in particular as a power outlet or as a USB socket.

[0031] The object underlying the invention is also achieved by a partition arrangement, wherein the partition arrangement comprises at least two partition elements. The partition elements are connected to one another by means of a connector. The partition elements thus form a unit, wherein the connectors are preferably designed such that the partition elements can be pivoted relative to one another.

[0032] The partition wall elements can be arranged at an angle to each other.

[0033] This allows a workstation to be spatially separated from an adjacent area on more than one side. In particular, the partition elements can be arranged essentially at right angles to each other, but in principle, it is conceivable to arrange the partition elements at an angle between 0° and 180°. More than two partition elements can be connected and arranged to enclose a space. The partition elements can be positioned, for example, in a rectangular or circular shape.

[0034] More than two partition elements can also be connected along an edge. This can be achieved using connectors that can accommodate more than two partition elements. This allows multiple partition elements to be arranged in a star, cross, or Y-shape. The partition elements are preferably pivotable relative to each other. This design allows, for example, several workstations to be separated—four in the case of a cross-shaped arrangement.

[0035] Some embodiments of the device according to the invention are explained in more detail below with reference to the figures. The figures show: Fig. 1 a partition wall element in a perspective view; Fig. 2 a schematic view of the partition wall element from Fig. 1 in a room; Fig. 3 a top view of the underside of the partition wall element from Fig. 1 ; Fig. 4 a section of a schematic cross-sectional view of the plate of the partition wall element from Fig. 1; Fig. 5 a schematic plan view of a partition wall with two partition wall elements.

[0036] The Fig. The partition wall element 1 shown in Figure 1 for a workplace 2 comprises a panel 3 designed as a sound absorber and a lighting device 4. The lighting device 4 is designed to illuminate the workplace 2.

[0037] The partition wall element 1 spatially separates the workstation 2 on one side from an adjacent area 5. The panel 3 serves as a visual screen due to its physical dimensions and as soundproofing due to its sound-absorbing properties.

[0038] The plate 3 is provided with a first main side 6 and a second main side 7 and with a plate length L, plate width B and plate thickness D (shown in Fig. 2 or Fig. 3). The first main side 6 and the second main side 7 are formed as opposing flat sides and are essentially rectangular. The distance from the first main side 6 to the second main side 7 corresponds to the panel thickness D, whereby the panel thickness D is smaller than the panel length L and the panel width B. The panel thickness D is 5 cm. The panel width B is 80 cm. The panel length L is 150 cm.

[0039] The plate 3 has a top side 8 and a bottom side 9. The top side 8 of the plate 3 extends along a first edge 10 of the plate 3 from the first main side 6 to the second main side 7.

A first end 14 of the holder 12 protrudes into the plate 3, wherein a second end 15 of the holder 12, opposite the first end 14, protrudes from the top side 8 of the plate 3. The lamp head 13 is arranged at the second end 15 of the holder 12. The holder 12 passes through the top side 8 of the plate 3, so that the holder 12 is connected to the plate 3 with its first end 14. The holder 12 is hollow so that an electrical connection of the lamp head 13 can be led through the holder 12 into the plate 3.

[0041] The lamp head 13 is connected to the holder 12 so that it can rotate about a longitudinal axis of the holder 12. This allows the lamp head 13 to be aligned so that the work area 2 to be illuminated is particularly well illuminated.

[0042] The holder 12 can be designed as a rod of constant length, the position of which can be moved along its longitudinal axis relative to the plate 3. For this purpose, the holder 12 can be at least partially recessed into the plate 3. This allows the distance between plate 3 and the lamp head 13 to be adjusted despite the constant length of the rod. The distance A_PL (shown in Fig. 2) between plate 3 and lamp head 13 is 50 cm.

[0043] The lamp head 13 comprises direct lamps 16 and indirect lamps 17.

[0044] The partition wall element 1 has two support feet 18, 19 for freely positioning the partition wall element 1 in rooms. The support feet 18, 19 are arranged on the underside 9 of the panel 3. The support feet 18, 19 are elongated.

[0045] A first support foot 18 is assigned to a first end 20 of the underside 9, and a second support foot 19 is assigned to a second end 21 of the underside 9 opposite the first end 20. The first support foot 18 is arranged at a distance from the second support foot 19, thereby improving the stability of the partition wall element 1 in the erected position.

[0046] The partition wall element 1 comprises a power connection for the power supply 22 of the partition wall element 1 (shown in Fig. 3). The power connection for the power supply 22 is electrically connectable to a power source and serves to supply power to the partition wall element 1, in particular to the lighting device 4. The power connection for the power supply 22 is assigned to the underside 9 of the partition wall element 1.

[0047] The partition wall element 1 also includes two power connections for power consumption 23, 24 (shown in Fig. 2 or Fig. 3).

[0048] The power connections for power consumption 23, 24 are used to connect an electrical consumer, in particular a monitor or a computer.

[0049] The power supply connection 22 and the two power outlet connections 23, 24 are designed as plug-in connectors, specifically as sockets. The power outlet connections 23, 24 are designed as sockets.

[0050] In Fig. 2, the partition wall element 1 shown is arranged in a room with a floor 25 and a ceiling 26, with the upper side 8 of the panel 3 being assigned to the ceiling 26 of the room and the underside 9 of the panel 3 being assigned to the floor 25 of the room. The partition wall element 1 is arranged on the floor 25 such that the partition wall element 1 protrudes substantially perpendicularly from the floor 25. The partition wall element 1 extends from the floor 25 toward the ceiling 26.

[0051] In Fig. 3, the second support foot 19 is in a setup position. In the setup position, a longitudinal axis 27 of the elongated support foot 19 is aligned perpendicular to one of the main sides 6, 7. In the setup position, the partition wall element 1 can be arranged particularly stably.

[0052] The first support foot 18 is in a storage position. In the storage position, the longitudinal axis 27 of the support foot 18 is aligned parallel to an edge of the underside 9, in particular the second edge 11. In the storage position, the partition wall element 1 can be stored or transported in a particularly space-saving manner.

[0053] The support feet 18, 19 are arranged to be rotatable and can be moved from the stand-up position to the storage position and / or from the storage position to the stand-up position by rotating the respective stand-up foot 18, 19.

[0054] Out of Fig. 4 shows that the plate 3 comprises a central layer 28 formed as a coconut mat. The coconut mat comprises fibers coated with natural rubber.

[0055] The panel 3 further comprises an intermediate layer 29, wherein the intermediate layer 29 comprises honeycomb cardboard. The honeycomb cardboard is perforated for improved sound permeability. The perforations have dimensions less than 0.1 mm. As a result, the intermediate layer 29 forms a sound-absorbing labyrinth.
