Description

Technical Field

[0001] This invention relates to a multi-layered waterproof rotating menu lightbox, belonging to the field of advertising sign technology. Background Technology

[0002] Existing outdoor menu lightboxes for restaurants are mostly fixed structures, making it inconvenient to change the images and difficult to adapt to the rapid image switching needs of breakfast, lunch, dinner, seasonal changes, and holiday marketing. Conventional outdoor menu lightboxes have many inherent drawbacks:

[0003] Most lightbox frames lack dedicated water channels, and the doors lack multi-level waterproofing structures. Rainwater easily seeps into the lightbox through frame gaps and door panel seams, easily causing damage to internal LED light sources and control electrical components due to moisture, resulting in high equipment failure rates and subsequent maintenance costs. Lightboxes with rotating functions on the market generally use all-metal bearing structures for their rotation transmission, which are prone to moisture and rusting, and rotational jamming during long-term outdoor use. They also lack reliable angle positioning and limiting structures, resulting in poor stability and easy deviation of the displayed image. At the same time, traditional lightboxes are mostly made by cutting, grooving, bending, and welding metal sheets, which is complicated by the production process, long production cycle, poor product assembly consistency, and difficulty in meeting the needs of enterprises for standardized mass production.

[0004] To overcome the aforementioned shortcomings, various improved lightbox structures have emerged in existing technologies, but all have significant technical limitations, only addressing isolated issues and failing to form a comprehensive solution. Waterproof lightboxes achieve basic waterproofing through a single-layer seal and simple water-blocking structure, and are mostly fixed static lightboxes, lacking the ability to rotate, limit angles, or perform modular assembly. Rotating lightboxes often use metal bearings and motors to achieve overall rotation, without multiple waterproof structures designed for outdoor scenarios. Water easily seeps into the hinge gaps, leading to significant corrosion and failure issues in the rotating mechanism, and there is a lack of precise angle limiting structures. Improved bearing components only optimize the bearing's load-bearing capacity but lack a suitable system for waterproofing the lightbox body, separate rotation, quick image changes, and modular production. Summary of the Invention

The skirt panel assembly has a square frame structure, which is wrapped by two detachable C-shaped frames and fixed to the outside of the panel assembly with screws.

[0016] Compared with the prior art, the present invention has at least one of the following beneficial effects: This invention allows for changing the image by opening the cabinet door of the cabinet assembly and replacing the drawing board or drawing paper in the gap between the bottom plate of the inner door and the transparent plate of the inner door. This adapts to the needs of rapid image switching for breakfast, lunch and dinner, seasonal changes and holiday marketing.

[0017] The enclosure assembly of this invention features water-guiding channels and double waterproof edges, effectively preventing water leakage inside the lightbox and protecting the electrical components. The water-guiding channels on the main frame allow for rapid drainage of rainwater, while the outer door frame is surrounded by waterproof supports, creating a secondary waterproofing layer. This effectively prevents rainwater from entering the enclosure assembly, protecting internal electrical components such as LED lights and preventing damage to the light source and control electronics from moisture. This reduces equipment failure rates and subsequent maintenance costs, and extends product lifespan.

[0018] The system employs upper and lower nylon bushings (top and bottom bushings) in conjunction with cylindrical rotating shafts (upper and lower shafts), ensuring smooth rotation, wear resistance, quiet operation, and rust prevention. The bottom of the housing features magnetic fixing blocks and support legs for stability, maintaining the desired angle after rotation and ensuring safe and reliable operation. This design results in a low failure rate and reduces the likelihood of jamming or malfunctions.

[0019] The main frame of the cabinet has legs at the bottom and magnetic fixing blocks on them, which enable reliable angle positioning and limiting, improve stability during use, and prevent the display screen from shifting.

[0020] The lightbox features an angled design to ensure optimal visibility for drivers and passengers. Viewers can easily see the image without looking up or shifting their posture, avoiding glare and ensuring clear visuals for safer driving. The angled design does not increase wind resistance or construction costs, is sturdy and durable, and enhances advertising effectiveness. It also optimizes rainwater drainage, reduces the impact of sunlight, slows down product aging and fading, and reduces future maintenance costs.

[0021] The lightbox assembly can be manually rotated to switch between different menu screens, meeting the needs for rapid updates in the morning, noon, evening, seasons, and holidays; the LED lights inside the assembly emit light evenly, the screen is clear and eye-catching, and the display effect is good.

[0022] This invention uses a combination of various aluminum profiles and modular profile splicing to simplify the processing flow, shorten the production cycle, reduce manufacturing costs, and make the product quality more stable, making it suitable for mass production.

Detailed Implementation

[0025] To make the present invention more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0026] Example 1 This invention provides a multi-layered waterproof modular rotating menu lightbox, such as... Figure 1 , Figure 3 As shown, it includes an inner support 1, a column front panel 2, a picture frame panel assembly 3, a column back panel 4, an upper panel 5, a cap 6, an upper pivot 7, a lower pivot 8, a panel assembly 9, a skirt assembly 10, a left box assembly 11, and a right box assembly 12. The left box assembly 11 and the right box assembly 12 are rotatably mounted on the left and right sides of the inner support 1, respectively, and their upper and lower ends are rotatably connected by the upper pivot 7 and the lower pivot 8, respectively. The column front panel 2 and the column back panel 4 are respectively located at the front and rear positions of the inner support 1. The picture frame panel assembly 3 is fixed to the front surface of the column front panel 2. The panel assembly 9 is fitted onto the outer side of the bottom of the inner support 1. The column front panel 2 and the column back panel 4 are located above the panel assembly 9. The skirt assembly 10 is fitted onto the outer side of the panel assembly 9. The upper end of the inner support 1 passes through the upper panel 5 and is fixedly connected to the upper panel 5. The cap 6 is fixed to the upper surface of the upper panel 5. Among them, the left box assembly 11 and the right box assembly 12 are the same two box assemblies.

[0027] The inner support 1 includes a column 1-1, the lower end of which is welded to the center of a base plate 1-2. The base plate 1-2 is a circular plate structure, with multiple oblong holes around the column 1-1 for securing it to the ground with screws. The column 1-1 is symmetrically arranged on its left and right sides, and each side is welded to one end of two upper and lower box support rods 1-3. The other ends of the two box support rods 1-3 are rotatably connected to the middle of the upper and lower ends of a box assembly (left box assembly 11 or right box assembly 12). The upper end of the column 1-1 passes through the middle of the upper panel 5. The two sides of the upper panel 5 are fastened to the box support rods 1-3 on the upper left and right sides of the column 1-1 with screws. The upper end of the upper panel 5 is fastened to the periphery of the cap 6 with screws. The upper end of the column 1-1 is located between the upper panel 5 and the cap 6, which covers the upper surface of the upper panel 5. The front and back panels of the column 1-1 are respectively provided. The bottom of the column 1-1 is covered with a panel assembly 9 and a skirt assembly 10.

[0028] The other end of the two box support rods 1-3 is provided with a first rotating shaft hole 1-3-1 arranged longitudinally, and a second rotating shaft hole 12-1-2 is provided at the middle position of the upper and lower ends of each box assembly. The upper rotating shaft 7 and the lower rotating shaft 8 pass through the first rotating shaft hole 1-3-1 of the upper and lower box support rods 1-3 and the second rotating shaft hole 12-1-2 at the upper and lower ends of each box assembly in sequence, so that each box assembly can rotate between the upper and lower box support rods 1-3.

[0029] In this embodiment, as Figure 2 As shown, the left box assembly 11 and the right box assembly 12 form a 6° angle with the vertical plane containing the left and right directions of the column 1-1. That is, the central axes of the box support rods 1-3 on both sides of the column 1-1 are located on the same plane, and both the left box assembly 11 and the right box assembly 12 form a 6° angle with this plane.

[0030] The lightbox features a 6° tilt angle, ensuring optimal visibility for occupants standing in the center of the lightbox, allowing them to see the image directly without looking up or shifting their posture. This near-direct viewing improves image information reception efficiency. Simultaneously, by optimizing panel reflection direction, it effectively reduces sunlight reflection during the day and direct glare at night, enhancing image clarity and driver safety. The small tilt angle does not compromise the overall structural stability of the lightbox, nor does it increase wind resistance or construction costs. It extends the effective exposure time of the advertisement, increasing image dissemination. Furthermore, it optimizes rainwater drainage and reduces direct sunlight intensity, slowing down product fading and light source aging, extending product lifespan, and reducing long-term maintenance costs.

[0031] In this embodiment, horizontal bars 1-5 are respectively provided below the box support rods 1-3 on the lower left and right sides of the column 1-1. One end of each horizontal bar 1-5 is welded to the column 1-1, and the other end of each horizontal bar 1-5 is welded to the vertical bar 1-4. A certain gap is provided between the upper end of the vertical bar 1-4 and the corresponding box support rod 1-3 at the lower part of the column 1-1. The vertical bar 1-4 is mainly used to fix the panel assembly 9. An angle steel 1-6 is provided at the position where each box support rod 1-3 and horizontal bar 1-5 connects to the column 1-1. The angle steel 1-6 is fastened to the box support rod 1-3, horizontal bar 1-5, and column 1-1 respectively by screws. A wire through hole is provided on the column 1-1 below the horizontal bar 1-5.

[0032] The front panel 2 of the column includes a front panel body 2-1. A first column groove 2-2 is provided at the middle position of the rear side of the front panel body 2-1. The column 1-1 is embedded in the first column groove 2-2. Both ends of the rear side of the front panel body 2-1 are provided with back panel insertion grooves 2-3 for snapping on the column back panel 4. The back panel insertion grooves 2-3 are C-shaped.

[0033] The column back panel 4 includes a back panel body 4-1, with bent edges 4-2 at both ends. The back panel body 4-1 is a flat plate structure, and the bent edges 4-2 are formed by bending the two sides of the flat plate. That is, the back panel body 4-1 and the bent edges 4-2 are integrally formed structures. Among them, the bent edges 4-2 are open-ended U-shaped structures. The bent edges 4-2 are inserted into the back panel insertion slots 2-3.

[0034] The picture frame panel assembly 3 includes a picture frame panel body 3-1, on which multiple installation windows 3-2 are provided for mounting a display screen (or touch screen) with an operating interface and speakers, etc. In this embodiment, the installation windows 3-2 are arranged vertically from top to bottom along the picture frame panel body 3-1. The display screen and speakers are all connected to a PLC controller, and the display screen, speakers, and PLC controller are all connected to a power supply. The power supply can be combined with the light box using the same power supply, or they can be separate. The PLC controller is equipped with wireless transmitters and receivers, thereby connecting to the computer host in the restaurant. By operating on the display screen, customers can view the menu and order food.

[0035] The upper panel 5 includes an upper panel body 5-1. The overall surface of the upper panel body 5-1 is a hollow cuboid structure with an open top. A central hole is provided at the center of the bottom of the upper panel body 5-1 for the column 1-1 to pass through. A first clearance groove 5-2 is provided at the bottom of the upper panel body 5-1, extending from left to right. After the column 1-1 passes through the central hole of the upper panel body 5-1, the first clearance groove 5-2 of the upper panel body 5-1 sits on the two box support rods 1-3 on the upper part of the column 1-1, and the bottom of the upper panel body 5-1 is fastened to the two box support rods 1-3 by screws. In this embodiment, the width of the first clearance groove 5-2 matches the thickness of the box assembly.

[0036] The brim 6 is a flat plate structure. The four sides of the brim 6 are fastened to the four sides of the top of the upper panel body 5-1 by screws, and the end of the post 1-1 that passes through the central hole of the upper panel body 5-1 is located in the cavity between the bottom of the upper panel body 5-1 and the brim 6.

[0037] The upper rotating shaft 7 and the lower rotating shaft 8 have the same structure. They are both composed of a flat plate and a straight rod welded or integrally formed in the middle of the flat plate. The flat plate is provided with multiple small holes around the straight rod. Screws are used to pass through the small holes in sequence and the corresponding small holes around the first rotating shaft hole 1-3-1 of the upper and lower box support rods 1-3, so as to fasten the upper rotating shaft 7 and the lower rotating shaft 8 to the upper and lower box support rods 1-3.

[0038] The panel assembly 9 includes a rear half-base 9-1 and a front half-base 9-2, which are fastened together with screws. Grooves are provided on the connecting surfaces of the rear half-base 9-1 and the front half-base 9-2. The grooves on the rear half-base 9-1 and the front half-base 9-2 combine to form a second column groove 9-4. A column 1-1 is disposed within the second column groove 9-4 and is clamped by the rear half-base 9-1 and the front half-base 9-2. A second clearance groove 9-5 is provided on the top surface of the assembled rear half-base 9-1 and the front half-base 9-2. Two box-type support rods 1-3 at the lower part of the column 1-1 rest within the second clearance groove 9-5. In this embodiment, the width of the second clearance groove 9-5 matches the thickness of the box assembly. A vertical rod hole 9-3 is provided at the connection position between the rear half base 9-1, the front half base 9-2, or the rear half base 9-1 and the front half base 9-2, so that the vertical rod 1-4 can pass through or be clamped, and is fastened to the vertical rod 1-4 by screws on the side of the rear half base 9-1 and / or the front half base 9-2.

[0039] The skirt panel assembly 10 has a square frame structure. It is wrapped around the panel assembly 9 by two detachable C-shaped frames and the C-shaped frames are fixed to the outside of the panel assembly 9 by screws.

[0040] like Figure 4 As shown, the box assembly (left box assembly 11 or right box assembly 12) includes a main box frame 12-1, and box doors 12-2 are rotatably connected to the front and rear ends of the main box frame 12-1.

[0041] like Figure 4 , Figure 5As shown, the main frame 12-1 of the housing includes a main frame body 12-1-1. A second pivot hole 12-1-2 is provided at the middle of both the top and bottom of the main frame body 12-1-1, for rotatable connection with the upper pivot 7 and lower pivot 8, respectively. A top bushing 12-1-7 is fixed at the position of the second pivot hole 12-1-2 directly opposite the top of the inner wall of the main frame body 12-1-1. A top bushing 12-1-7 is fixed at the position of the second pivot hole 12-1-2 directly opposite the bottom of the inner wall of the main frame body 12-1-1. A bottom bushing 12-1-5 is fixed at position 1-2. The lower end of the upper rotating shaft 7 passes through the second rotating shaft hole 12-1-2 at the top and is located inside the top bushing 12-1-7. The upper end of the lower rotating shaft 8 passes through the second rotating shaft hole 12-1-2 at the bottom and is located inside the bottom bushing 12-1-5. The upper end of the lower rotating shaft 8 abuts against the top inside the bottom bushing 12-1-5 to support the box assembly. This creates a gap between the bottom of the main frame body 12-1-1 of the box and the box support rod 1-3, meaning that the two do not directly contact each other. Both the bottom bushing 12-1-5 and the top bushing 12-1-7 are made of nylon. Nylon itself has good lubrication and a low coefficient of friction, resulting in smooth rotation, uniform resistance, and resistance to jamming even after prolonged operation. (In contrast, stainless steel, due to its inherent lubrication and low coefficient of friction, exhibits smooth rotation and uniform resistance, making it less prone to jamming even after prolonged operation.) The main frame body 12-1-1 of the enclosure has water guide grooves 12-1-4 on all four sides of its front and rear ends. The water guide grooves 12-1-4 are annular grooves with their openings facing outwards (around the perimeter). The bottom of the main frame body 12-1-1 of the enclosure has a first through hole 12-1-8 and a second through hole 12-1-9. The first through hole 12-1-8 is used to install the support legs 12-1-6 with screws. There are at least two sets of the first through holes 12-1-8, with at least two in each set. The two sets of first through holes 12-1-8 are located on the left and right sides of the second pivot hole 12-1-2 at the bottom, respectively. The two support legs 12-1-6 are located on the front and rear sides of the bottom of the main frame body 12-1-1 of the enclosure, respectively, and the two support legs 12-1-6 are symmetrical about the second pivot hole 12-1-2 at the bottom. The second through hole 12-1-9 is used to pass through various wires.Each support leg 12-1-6 has a magnetic fixing block on its inner side (i.e., the side closest to the centerline of the main frame body 12-1-1). When the support leg 12-1-6 approaches the support rod 1-3, the magnetic fixing block causes the support leg 12-1-6 to adhere to the support rod 1-3, thus limiting the position of the assembly and restricting its position when not in use. The angles formed by the left and right assembly 11 and the vertical plane containing the left and right directions of the column 1-1 are determined by the position of the support leg 12-1-6 at the bottom of the main frame body 12-1-1.

[0042] like Figure 9 As shown, the back of column 1-1 is provided with a cable outlet hole 1-1-1 and a grounding terminal 1-1-2. LED lights 12-3-1 are arranged around the inner wall of the main frame 12-1 of the enclosure. Each LED light 12-3-1 is connected to one end of a wire. A grounding wire 12-3-2 is connected between the main frame 12-1 and the enclosure door 12-2. The other end of the wire and the other end of the grounding wire 12-3-2 are respectively connected to one end of a conductive slip ring (hereinafter referred to as slip ring) inside the bottom bushing 12-1-5 or the lower rotating shaft 8. The other end of the conductive slip ring is connected to another wire and another grounding wire. The other wire and the other grounding wire pass sequentially through the bottom bushing 12-1-5 and the lower rotating shaft 8, respectively, and then connect to the inside of column 1-1 through the cable inlet hole on the side of column 1-1. One grounding wire is directly grounded, and the other wire passes through the outlet hole 1-1-1 and is sequentially connected to junction box 12-3-4, switching power supply 12-3-5, switch junction box 12-3-7, and AC line junction box 12-3-8. Both the inlet and outlet ends of switch junction boxes 12-3-7 and 12-3-4 are equipped with waterproof connectors 12-3-3, through which the wires are connected. Switch junction box 12-3-7 has a crank switch 12-3-6. Junction boxes 12-3-4, switching power supply 12-3-5, switch junction box 12-3-7, and AC line junction box 12-3-8 are also connected to grounding terminal 1-1-2. This circuit structure is a conventional wiring method for existing lighting circuits and therefore will not be described in detail.

The size of the inner door frame 12-2-2 is smaller than the size of the outer door frame 12-2-1, and the inner door frame 12-2-2 is fitted inside the outer door frame 12-2-1. The inner wall of the central hole in the outer door frame 12-2-1 is sealed and fixedly connected to the perimeter of the outer door transparent panel 12-2-4. The inner wall of the central hole in the inner door frame 12-2-2 is fixedly connected to the perimeter of the inner door bottom plate 12-2-5 and the perimeter of the inner door transparent panel 12-2-6, respectively. Figure 6 , Figure 7 , Figure 8 As shown, a certain gap is provided between the bottom plate 12-2-5 of the inner door and the transparent plate 12-2-6 of the inner door, for placing drawing boards or papers with different patterns. A waterproof edge 12-2-7 is provided around the rear end of the outer door frame 12-2-1 and around the outer perimeter of the inner door frame 12-2-2. When the main frame 12-1 of the box and the box door 12-2 are assembled together, the waterproof edge 12-2-7 is fitted onto the outside of the water guide channel 12-1-4, so that rainwater entering from the gap between the main frame 12-1 of the box and the box door 12-2 can slide into the water guide channel 12-1-4 along the front and rear ends of the main frame 12-1 or the outer surface of the waterproof edge 12-2-7.

[0044] like Figure 8 As shown, a leak-proof support edge 12-2-8 is provided around the inner wall of the waterproof edge 12-2-7. The leak-proof support edge 12-2-8 is located near the end of the outer door frame 12-2-1 of the box, but not on the end. The position of the leak-proof support edge 12-2-8 is located inside the water guide channel 12-1-4. The leak-proof support edge 12-2-8 prevents rainwater that has slipped in from the gaps along the outer surface of the waterproof edge 12-2-7 from continuing to move along the inner surface of the waterproof edge 12-2-7 towards the inner door frame 12-2-2 of the box. The leak-proof support edge 12-2-8 can block the rainwater and allow the rainwater to flow down along the leak-proof support edge 12-2-8 until it drips into the water guide channel 12-1-4.

[0045] The bottom of the outer door frame 12-2-1 of the enclosure is provided with a third through hole 12-2-10. The third through hole 12-2-10 is opened on the waterproof edge 12-2-7 and is located inside the waterproof support edge 12-2-8 (on the side close to the inner door frame 12-2-2 of the enclosure). The third through hole 12-2-10 is a wire through hole.

The top and bottom of one side of the outer door frame 12-2-1 of the box are fastened with screws (rivets) to a second hinge piece 12-2-9. The first hinge piece 12-1-3 on the main frame body 12-1-1 of the box and the second hinge piece 12-2-9 on the outer door frame 12-2-1 of the box are rotatably connected. The first hinge piece 12-1-3 has a rotating hole at the end of the main frame body 12-1-1 on the outside of the box, and the second hinge piece 12-2-9 has a pivot at the end of the outer door frame 12-2-1 of the box. The pivot on the second hinge piece 12-2-9 is rotatably inserted into the rotating hole on the first hinge piece 12-1-3.

[0047] The usage process of this invention is as follows: When a driver approaches in a car or a pedestrian comes to view the menu lightbox, they can directly operate it from the center. The 6° angle formed by the left and right assembly 11 and the vertical plane of the column 1-1 provides a more suitable viewing angle, allowing the user to view the information without much movement. To view information on the back of the lightbox, the assembly can be rotated. After rotation, the magnetic fixing block causes the legs 12-1-6 to adhere to the support rod 1-3, preventing the assembly from wobbling. This fixed assembly facilitates easy viewing. This menu lightbox invention makes it convenient for passersby to access information.
