Description

Technical Field

[0001] This utility model relates to the field of elevator decorative ceiling technology, and in particular to an outward-turning ultra-thin decorative ceiling structure. Background Technology

[0002] Currently, with the increasing use of elevators in various buildings, the aesthetics of elevator interiors are receiving more and more attention. Customers have increasingly higher requirements for the styles and specifications of decorative ceilings inside elevator cars. They need to meet national standards and safety requirements, while also being simple, attractive, and practical. There are also requirements for later maintenance, such as making them as thin as possible, matching safety windows, and allowing for easy replacement of light fixtures, acrylic, and moving parts. Especially for home elevators, where customers use them themselves, they pay more attention to various details. In home elevator cars, decorative ceilings can provide lighting and enhance the overall visual effect.

[0003] There are many types of decorative ceilings for home elevators. A common type involves installing lighting tubes on the car ceiling or on the ceiling frame. The decorative ceiling consists of a surrounding frame and a milky-white translucent panel. However, due to limitations imposed by the structure, height, lighting fixtures, and the distance between the lights and the translucent panel, many decorative ceilings in home elevators do not provide uniform lighting. Ordinary decorative ceilings are relatively tall (typically 100mm for home elevators and around 150mm for passenger elevators), occupying a significant portion of the car height. While LED lighting on a flat car ceiling can achieve uniform lighting, it requires specific car ceiling dimensions, is more expensive, and has limitations on the length and width of the lighting fixtures. Below are a few other examples where improvements are possible:

[0004] 1. Currently, since the ceiling frame is welded as a whole, it can only be dismantled as a whole, which limits the possibility of future disassembly and reassembly.

[0005] 2. Elevators with decorative ceilings usually have their airflow directed outwards by slanted frame panels. When there is a need for secondary decoration of the elevator later, it is difficult to judge in time whether there will be interference or obstruction, and it is not as effective as direct airflow.

[0006] 3. Currently, decorative tops are installed after the car roof is installed, which requires raising the car roof and leaving someone on the car roof to tighten the bolts. This is especially difficult when there are few people and the decorative top is heavy. Utility Model Content

[0028] As attached Figure 1-3 The diagram shows the outward-folding ultra-thin decorative roof structure of this utility model, comprising a middle plate 1, frame bodies 2, and an outer decorative roof plate 3. The middle plate 1 is made of stainless steel and is firmly bonded to the car roof. Air outlets 11 are machined on the middle plate 1, providing direct airflow. The air outlets 11 are designed with various decorative hole styles. The frame bodies 2 are laser-bent stainless steel plates. Two frame bodies 2 are installed on both sides of the middle plate 1. Bolt holes 23 are machined on the frame bodies 2, and nuts are welded to the car roof. During on-site installation, simply pass bolts through the bolt holes 23 and tighten them to install the frame bodies 2 onto the car roof.

[0029] An LED light strip 4 and a power supply box 5 are installed on the frame body 2. Inner bent plates 21 are formed on both sides of the frame body 2, closer to the middle plate 1, and outer bent plates 22 are formed away from the middle plate 1, as shown in the attached diagram. Figure 6 As shown, a nut 6 is welded onto the inner bent plate 21, as per the attached diagram. Figure 5 As shown, a stainless steel hinge 7 is installed on the outer bent plate 22. A light-transmitting plate 8 is installed on the outer decorative top plate 3 to ensure uniform light output from the LED light strip 4. The outer decorative top plate 3 is rotatably connected to the frame body 2 via the stainless steel hinge 7. The side of the outer decorative top plate 3 away from the stainless steel hinge 7 is bent to form an outer extension 31, and the outer extension 31 is machined with mounting holes corresponding to the nuts 6. The outer decorative top plate 3 includes an open state and a closed state, as shown in the attached diagram. Figure 7 As shown, when in the open state, the exterior decorative top panel 3 naturally sags under the influence of gravity, as indicated in the attached diagram. Figure 4 As shown, when in the closed state, the outer decorative top plate 3 is parallel to the frame body 2, and the outer extension 31 is parallel to the inner bent plate 21. A screw 9 connected to the nut 6 on the inner bent plate 21 is installed in the mounting hole of the outer extension 31. In this embodiment, the screw 9 is an M4 Phillips head countersunk screw, and the nut 6 is an M4 Phillips head countersunk nut.

[0030] A silicone light strip 10 is installed on the side of the outer extension 31 away from the inner bending plate 21, blocking the screw 9 on one side and making the overall appearance brighter and more beautiful. The silicone light strip 10 has a magnetic positive pole, and the outer decorative top plate 3 has a magnetic negative pole, ensuring that the positive and negative poles attract each other. Under normal conditions, the magnetic lock prevents it from moving. Only when manually operated can the silicone light strip 10 be lifted by hand to release the magnetic attraction, so that the outer decorative top plate 3 can be opened at any time to replace the LED light strip 4 and the light-transmitting plate 8, making disassembly and assembly more convenient.

[0031] When in the closed state, the distance between the top surface of the frame body 2 and the bottom surface of the outer decorative top plate 3 is 48.5mm, with only the thickness of the middle plate 1 and the glue in between. Except for the integrated flat car roof, it basically meets and is smaller than most decorative tops on the market.

[0032] When there is a need for a safety window, the middle plate 1 can be made into a middle notch plate and a safety window cover plate to meet the safety window requirements.

[0033] This utility model features an ultra-thin, outward-folding decorative roof structure that is extremely lightweight and thin. Bolt holes 23 are machined into the frame body 2, and nuts are welded onto the car roof. During on-site installation, simply pass bolts through the bolt holes 23 and tighten them to install the frame body 2 onto the car roof. Screws 9 are used to close and lock the outer decorative roof panel 3 to the frame body 2. This simple operation can be performed by one person inside the car, improving installation efficiency. It also saves significant labor costs for later maintenance, upkeep, disassembly, replacement of light fixtures, light-transmitting panels, and even replacement of the entire decorative roof. This utility model has a simple process, low cost, and convenient production and processing. Maintenance and replacement are also convenient, saving time and effort. It meets the needs of various low-height home elevator customers, offering an aesthetically pleasing and spacious appearance, while also providing direct airflow without taking up much space.
