Ceiling profile connection unit for light lines

Description

[0001] The utility model relates to the field of construction and can be used for the placement and installation of lighting structures, for example, LED lighting, during the installation of suspended and plasterboard ceilings.

[0002] From the field of technology, corner profiles for connecting Flexy LINE 30 ceiling profiles for installing light lines [1] (https: / / mario-potolok.ru / catalog / profili / gotovye-uzly / ugol-90-flexy-line-30-pf6838-svetovye-linii-30-mm-20-20sm / ?ysclid=mp3qe7w6mo860884807), made of aluminum, as well as their plastic (PVC) versions for installing stretch ceilings [2] (https: / / viaperfecto.ru / flexy30) are widely known.

[0003] In addition, PVC corner profiles for light lines are widely distributed and available on the market through online platforms, such as “90 degree corner for light lines” [3] (https: / / www.wildberries.ru / catalog / 283923945 / detail.aspx).

[0004] A unit is known for connecting profiles of light lines of a suspended ceiling at various angles [4] (Patent RU No. 2856894, published 02 / 25 / 2026), made with the possibility of installation between the profiles being connected and connecting with them, characterized in that at least one through hole is made in the body of the unit, providing the possibility of outputting an LED strip with connected power wires.

[0005] A common drawback of the above-mentioned analogs is the low reliability of the design during installation of lighting elements (LED backlighting), caused by the need to dismantle the structure in the event of a lighting equipment failure. The frequent failure of the lighting equipment is due to the fact that the installation of lighting in the rotary / corner units [1]-[3] is carried out by bending the LED strip (https: / / yandex.ru / video / preview / 10961391710610996369) or using a special rotary connector. This increases the risk of breakage, since the number of system elements (in the case of a connector) increases and the conductivity / operability of the connection (due to bending) of the LED backlight is impaired.To troubleshoot this issue, partial or complete dismantling of the structure is required. Products [1]-[4] lack a mechanism for securing adjacent profiles being installed. Therefore, reassembly / disassembly will result in increased freedom of movement between the connections, and if adhesives were used, complete failure and replacement of the assembly. Furthermore, the presence of at least one through-hole [4] for the LED strip with its attached power wires reduces the overall strength of the assembly and does not regulate the rotation of the lighting elements.

[0006] The technical result of the proposed utility model is to increase the reliability of the connection unit for ceiling profiles for light lines when used in conjunction with lighting equipment. This is achieved by securing adjacent profiles, allowing for safe installation / replacement (without the risk of damage and subsequent dismantling / repair) of the unit, and by reducing the risk of such a need by improving the integrity of the lighting equipment used.

[0007] The technical result is achieved in that the connection unit for ceiling profiles for light lines includes the body of the unit, characterized in that the body of the unit is provided with a recess and consists of supporting walls, wherein the recess is made cylindrical, and the supporting walls are provided with fixing elements.

[0008] The outer surface of the recess can be chamfered.

[0009] The recess can be made rectangular.

[0010] The essence of the claimed utility model is explained by the drawings, where Fig. 1 shows a cross-shaped (with an angle of 90°) example of implementing a connection unit for ceiling profiles for light lines (top view), Fig. 2 shows a cross-shaped (with an angle of 90°) example of implementing a connection unit for ceiling profiles for light lines (bottom view), Fig. 3 shows an angular example of implementing a connection unit for ceiling profiles for light lines (top view), Fig. 4 shows an angular example of implementing a connection unit for ceiling profiles for light lines (bottom view), Fig. 5 shows a cross-shaped (with an angle of 60°) example of implementing a connection unit for ceiling profiles for light lines (top view), Fig. 6 shows a cross-shaped (with an angle of 60°) example of implementing a connection unit for ceiling profiles for light lines (bottom view), Fig. 7 shows an angular example of implementing a connection unit for ceiling profiles with a fixing element of the profiles (ears).

[0011] In Fig. 1-7, the following notations are used:

[0012] 1 - supporting wall;

[0013] 2 - recess;

[0014] 3 - fixing element (ears).

[0015] The ceiling profile connection unit for light lines is made of polymer materials using 3D printing or injection molding. The material used can be PETG, ABC, PLA, or other plastics.

[0016] The connection unit for ceiling profiles for light lines (Fig. 1-7) includes the body of the unit, consisting of support walls 1, made at an angle to each other, with a recess 2 made between the support walls, and each support wall is additionally equipped with a fixing element 3 (ears).

[0017] Recess 2 is incorporated into the design of the ceiling profile connection for the light lines during the 3D printing (casting) stage or is created mechanically afterwards. Recess 2 is designed with a bottom thickness of 0.7-1 mm, with the most acceptable recess shape being cylindrical. If, for example, LED backlight wiring is needed, this wall can be easily pierced with any convenient tool, drilled with a drill, or partially (at the edge) bent, serving as a plug (screen or curtain), without significantly affecting the overall integrity of the structure. Moreover, there is no need to dismantle this plug or completely drill out (the entire surface). Making the bottom of Recess 2 less than 0.7 mm thick increases the risk of defects during the printing (casting) stage.

[0018] If a reduction is necessary, a chamfer (not shown in the figure) is applied to the outer portion of recess 2. Depending on the quality of the printing (casting), this helps eliminate additional risks caused by possible damage when installing lighting equipment.

[0019] Each support wall 1 is equipped with fixing elements 3 (one on each side). Fixing elements 3 are protrusions (ears) with holes for securing the connection between the ceiling profiles for the light lines and adjacent profiles using, for example, self-tapping screws. This connection allows for a secure and tight fixation of the final assembled structure, eliminates play, and can be disassembled / reassembled if necessary (for repairs) without damaging or altering the adhesion of the connection between the ceiling profile and the adjacent profile.

[0020] The shape of recess 2 of the ceiling profile connection node for light lines is designed to allow smooth rotation of the lighting equipment (LED strip) along its radius. Examples of this design are shown in Figs. 1, 3, and 5. Changing the shape of recess 2 to a square / rectangular shape, etc., is permissible to provide additional space for placing, rotating, or pivoting the equipment to reduce the risk of bending / kinking.
