DETAILED DESCRIPTION OF THE INVENTION

[0041] The devices and methods discussed herein illustrate specific ways of making and using this invention and should not be interpreted as an exclusive and complete description of the technology's capabilities.

[0042] While the devices and methods are described herein with a certain degree of specificity, it should be noted that many modifications can be made to the design details and arrangement of the devices and components without departing from the spirit and scope of this disclosure. It is understood that the devices and methods are not limited to the embodiments set forth herein for purposes of illustration.

[0043] In general, the invention relates to a new, lightweight modular suspended ceiling suspension system that has an improved appearance and accommodates a variety of applications. More specifically, the system allows quickly and by utilizing a minimum number of elements to install suspended ceilings of various complexity, to level unevenness of the bearing ceiling in the buildings.

[0044] One of the advantages of the system of the invention is the ability to ensure the full and uniform functioning of a majority of the systems hidden by a suspended ceiling, including ventilation and air conditioning of the room without use of additional devices. The design of this system assumes the possibility of uniform placement of lighting systems between the decorative panels of the suspended ceiling, for example, LED equipment with or without a diffuser. The suspension system of the decorative ceiling panels allows to quickly mount and dismantle such panels. This provides an additional advantage in quick and full access to any sector of the space covered by the suspended ceiling, as well as the ability to quickly change decorative panels. The latter might occur when changing a design of a room, replacing a damaged panel, adding additional functional devices, etc.

[0045] Due to a predetermined distance (for example, 30 mm) between the installed ceiling decorative panels, a full-fledged heat and mass transfer between the air mass of the room and the space above the suspended ceiling is ensured. Further, the distribution of supply and/or cooled and heated air is improved. Thus, the system of the invention does not require the introduction of special gratings, diffusers and other elements on the surfaces of decorative panels. At the same time, the invention can provide a uniform distribution of various flows due to the system of slots between the panels. In the absence of ventilation and air conditioning systems in the space above the suspended ceiling, the system of slots between the decorative panels can be used, for example, for the location of lighting devices. In practice, however, a compromise use for both needs at the same time is more common.

[0046] When using materials with a relatively high heat capacity in the manufacturing of the ceiling decorative panels, it is possible to achieve some accumulation of heat or cold when blowing these panels with air at a given temperature. Efficient heating or cooling can also be achieved by the direct contact of the heating/cooling circuits with decorative panels having suitable characteristics for the efficient heat exchange.

[0047] Additional options can include, for example, the installation of a layer of soundproofing material as part of decorative panels. This may occur in the case of using a suspended ceiling in crowded places or in industrial premises.

[0048] Due to the sufficient rigidity of the finishing ceiling panels, it is possible to suspend a variety of devices on/from their surfaces. Such devices might include additional lamps, heaters, surveillance cameras, sprinklers and other fire-fighting devices, all kinds of sensors. antennas, small audio and video devices, fans, devices for cleaning, humidification, aromatization, ionization, UV sterilization, etc., the devices which can be relevant for the industrial and home usage.

[0049] It is possible to simplify the manufacture/assembly of the suspended ceiling according to the present invention. Most of the applicable items can be assembled in five minutes or less, keeping labor costs at a reasonable level.

[0050] Practically all parts of the modules have standard dimensions and are made with sufficient accuracy and assembled into finished products without additional fasteners.

[0051] Thus, the system of the invention provides not only a decorative partition, but also is a full-fledged element of a modern room, which not only complements the functionality of the existing systems and at the same time elevates the shortcomings of the ceiling space.

[0052] Referring now specifically to FIGS. 1-7 illustrating various features of a modular suspended ceiling assembly 10 of the invention including multiple decorative panels 25 spaced from each other and suspended from a support structure by a plurality of suspension members 22. Each panel is formed by spaced from each other first 42 and second 44 connecting walls interconnected by front 46 and rear 48 walls. First and second spaced from each other main brackets 26 extend outwardly from the first connecting wall 42. First and second separated auxiliary brackets 27 extend outwardly from the second connecting wall 44. Each main bracket 26 is formed by a connecting portion 50 connected to an inner part of the first connecting wall 42 and an engaging portion 52 extending from the connecting portion and having a hook formation 54 oriented towards an inner region of the panel. Each auxiliary bracket 27 is formed by a connecting portion 56 attached to an inner part of the second connecting wall 44 and an engaging portion 58 extending from the connecting portion and having a hook formation 60 having two hook members 62 separated by a space 61 and oriented towards an exterior of the panel. A plurality of suspension members 22, with each member including a rod 23 extending between distal and proximal ends thereof, wherein the distal end is adjustably attached to a hollow support structure 24.

[0053] A plurality of guides/rails 30 and cross members arranged in a generally rectangular grid. The guides/rails 30 pass through and supported by said hollow support structure 24 for each respective suspension member 22.

[0054] The module 12 is formed by the adjacent panels 5 supported by a single rail 30 passing through and supported by the support structure 24 through the engagement of the respective hook formations of the main and auxiliary brackets with the rail 30, wherein each hook formation 54 of the main bracket 26 of one panel is disposed within the space 61 between the hook members 62 of the auxiliary bracket 27 of the other panel. The assembly of the invention also includes a lighting (LED) profile 31, a lighting profile bracket 29 with a gap 32 between decorative modules and connecting plates 39 for connecting edges of the decorative panel.

[0055] Among essential elements of the suspension arrangement are fasteners 21 associated with the supporting structure, threaded rods/studs 23 for adjusting the elevation/height of the ceiling plane, hollow support structures or guide retainers 24 used, among other things, to adjust the position of the ceiling plane, guides or rails 30 for positioning the decorative panels 25 within the system.

[0056] A significant part of the ceilings, rooms or otherwise enclosed interior spaces defined by simple geometric shapes, in particular, they have rectangular and square shapes. In such cases, it is often not necessary to design and manufacture special decorative panels, and the task of installing a false ceiling is solved with the help of universal elements, in the extreme case, converted using relatively simple and commonly available tools at the installation site. This approach is generally applicable for rooms with more complex ceiling configuration.

[0057] According to the method of the invention, surface preparation for mounting begins with marking the surface of the ceiling (or other supporting structure) for fastening the adjustable elements of the suspended support structure for the guide or rail. In this example, the metal rods or studs 23 are utilized. This function can be performed by any other more accessible or more suitable fastener for a specific task.

[0058] In this example, the number of the rods or studs and the distance between them is determined by the materials of the suspended ceiling, its planned load, as well as the material and load-bearing capacity of the ceiling or the structure on which the suspended ceiling is mounted.

[0059] The system allows installation in a reinforced concrete floor application, made in-situ, including a concrete floor with a profiled metal sheet as a fixed formwork, or prefabricated from individual reinforced concrete slabs, in wooden beams, metal beams of various sections, channels, pipes, orthotropic slabs and other structures, with sufficient strength and bearing capacity. In the standard version, which involves the use of steel for the manufacture of the ceiling suspension system and aluminum composite with a thickness of 5 mm for the manufacture of decorative panels, the weight of the ceiling without lighting is about 13 kg/m2.

[0060] The ceiling suspension system can be made from a variety of materials such as steel pipes (coated or uncoated), aluminum (coated or uncoated), tough engineering plastics, fiberglass, or a suitable combination. If desired, you can also use some types of wood that have sufficient strength and load-bearing capacity, especially certified sustainable lumber. In the example described, it is assumed that rolled metal (steel and/or aluminum) is used to manufacture the flow suspension system. It is recommended to use a protective powder coating (for steel) or anodizing (for aluminum) when using this system in coastal, tropical or cold temperate regions. In the case of using wood, it is recommended to use protective compounds against insect pests, mold, fungi and the effects of high humidity.

[0061] The fixing of the studs for hanging the ceiling guide is carried out mainly by fasteners, threaded members or dowels 21. The design and size of the dowel is selected based on the material of the bearing surface and the expected loads. In the case of fastening to metal structures. In the case of fastening to a concrete ceiling with a profiled metal sheet, both weld nuts and dowels can be used as permanent formwork. Do not install rods or studs 23 by welding directly to the metal of the supporting structure. In the case of a wooden floor, it is recommended to use, for example, square plates with a nut welded in the center and at least four holes for suitable wood screws at an equal distance from the nut closer to the corners of the plate.

[0062] After marking the places for hanging the rods or studs 23 and installing suitable fasteners 21, the studs are mounted by screwing them into such fasteners. Usually, the rods or studs 23 are located at a distance of 600 to 1200 mm from each other. Some error in the length of the rods or studs 23 is permissible in the case of a flat or relatively flat topography of the bearing surface. In case of large irregularities, the cutting of the necessary studs should be planned in advance. Usually, the length of the rods or studs 23 is from 100 to 600 mm, however, it does not limit the use of longer studs up to 2000 mm in special cases.

[0063] After attaching or screwing all the rods or studs 23 with one end into the fasteners 21 of the bearing surface, the retainers or support structures 24 are attached/provided for the guides/rails 30 at their opposite distal free end. In one embodiment the guide retainer or a support structure 24 can be a tubular element, for example, 20×40 mm and a length, for example, up to 50 mm, with a threaded element attached or welded to one of the narrow sides of the pipe from the outside. To expand the possibility of adjusting the height/elevation of the suspension of the guide in the section of the retainer pipe, a round through hole is drilled, located under the threaded element in such a way as to ensure the free entry of the thread stud into the retainer pipe. As the main element of the retainer or support structure 24, the use of a pipe section other than the section and/or size indicated here is not excluded. It is allowed to screw the retainers onto the studs before screwing the studs into the fasteners on the bearing surface.

[0064] After installing and adjusting to the predetermined height of all the clamps, it is possible to place the horizontally oriented rail or guide 30 of the suspended ceiling in them. In this example, a square pipe 15×15 mm is described, but this does not limit the choice of material, section profile and thickness of the guide. The pipe can in principle be inserted both longitudinally and transversely with respect to the selected room coordinate system. It is desirable that the length of the guide in this case be only slightly shorter than the distance between the walls in the room, wherein a particular guide is installed between such walls. For ease of installation, the guide 30 is cut, for example, into two separate elements with the location of the joint in the pipe of one of the guide clamps. In such cases, it is recommended to make a connecting spacer inside the guide tube to securely connect the guide. The second option for reliable fixation can be the addition of two horizontal clamping screws to the design of the latch—one at the end of each of the joined elements of the guide.

[0065] After installing all the guides 30, it is possible to directly mount the decorative panels 25. In the described embodiment square/rectangular aluminum composite panels (ACP) with a thickness of 5 mm can be utilized. However, a wide range of materials can be used for the system—metal, various plastics, wood, glass, fabrics and/or their various combinations, providing sufficient rigidity of the resulting element and allowing reliable fastening of brackets for hanging a decorative panel to it. The shape of the panel, other than square/rectangular, in the first approximation also does not play a decisive role, however, it creates a number of conditions and limitations for the described system. In the case of square/rectangular ACP, to give the finished element of the decorative panel the properties described above, for example, box-shape with smooth rib rounding radii. After that, the actual bending and final assembly of the panels is carried out, for example, by riveting small metal plates 39. Strengthening the rigidity of the panels can be achieved in other ways, for example, by increasing the thickness, the number of layers of material or by installing individual stiffeners, as well as other well-known means.

[0066] The decorative panel acquires its finished form after attaching the brackets, which in essence are a bent sheet steel product, in which it is possible to select a base for attaching to the panel and a hook for fixing the panel on a horizontal guide 4. A different design of brackets is allowed, in particular with a different engagement system, including for a guide with different dimensions and profile cross-section. Brackets can be divided into two types—main 26 and auxiliary 27. The main difference between the brackets described here is the length and number of hook formations. The auxiliary bracket 27 has two hooks 60 at a small distance/space 61 between them, and the main brackets 26 are formed with a single hook 54. This design allows, for example, to fix a number of decorative panels on one guide in the longitudinal direction relative to each other and makes it possible to obtain equal gaps between the panels by placing the hook 54 of the main bracket on one guide between the two hooks 62 of the auxiliary bracket of the other panel. A prerequisite for this is that the brackets must be positioned in the same way on all decorative ceiling panels, for example by using a suitable template.

[0067] The orientation of the hooks can be either inside the panel or outside. The type of brackets and the orientation of their hooks are determined mainly by the location of the guides relative to the walls.

[0068] The main brackets 26 are located on the opposite side of the decorative panel with respect to the auxiliary brackets 27. The number of such pairs is determined mainly by the weight of the decorative panel and the expected load on it; however, it cannot be less than two, in which case the pairs of brackets are located closer to the edges of the panel.

[0069] Suspension of decorative panels 25 is carried out in two steps: first, hooking is carried out to the first guide using auxiliary brackets with wider hooks, then final hooking is made to the second guide opposite using the main brackets. This approach allows you to position the decorative panel on the guide quickly, effortlessly and without the use of special tools.

[0070] Between the installed decorative panels 25, a certain distance of 32 is maintained, for example 30 mm. Such distance 32 can be greater, but this introduces additional requirements for the brackets of the decorative panel. In the specified gap between the decorative panels, for example, LED lamps can be mounted. In this case, it is possible to use, for example, a standard extruded aluminum profile 38 for LED lamps 31 having a strip with LEDs 34 and a light diffuser 35.

[0071] For an expedited installation, as a fixation device to the suspended ceiling a bracket 36 is used comprising a base for attachment to LED and two small hooks 37 for hanging on the guide 30.

[0072] The above-described invention results in a system containing a small number of standard elements, which can be manufactured on ubiquitous equipment without tight tolerances in terms of accuracy.
