Description

Technical Field

[0001] This invention relates to the field of furniture technology, and in particular to a frame-type wardrobe lighting system. Background Technology

[0002] A wardrobe is a cabinet for storing clothes, usually made of engineered wood or natural wood panels, combined with hardware accessories. The standard structure of this type of wardrobe is a fixed panel wardrobe, which cannot be adjusted after assembly. Each storage compartment is fixed and cannot be adjusted according to the type of clothing.

[0003] In recent years, some metal wardrobes have emerged, assembled with stainless steel, aluminum alloy, tempered glass and other hardware accessories. These metal wardrobes use detachable columns and panels, which are indeed relatively environmentally friendly and allow for some adjustment of clothing storage space.

[0004] However, existing metal wardrobes lack lighting systems, requiring external lighting for proper use in poorly lit environments, thus limiting their application scenarios. The absence of a dedicated lighting system means that additional surface-mounted lighting systems pose safety hazards due to exposed wiring, are unsightly, and suffer from low assembly efficiency and inconvenient installation.

[0005] Therefore, the market urgently needs a frame-type wardrobe lighting system that can solve the problems in existing technologies, overcome the shortcomings of existing wardrobes, achieve standardized wardrobe modules, have good detachability between components, high safety and reliability, facilitate wiring and lighting, and have an overall aesthetically pleasing appearance. Summary of the Invention

[0006] To address the problems in the prior art, this invention provides a frame-type wardrobe lighting system that is beneficial for saving construction costs, improving wiring efficiency, and enhancing the aesthetics and lighting of the wardrobe.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a frame-type wardrobe lighting system, comprising a transformer fixed to the wall, a wall track fixed to the wall, wire clips that can be snapped onto the wall track and the top plate, a hollow suspended top plate support device, and a hollow column; the column has a light groove for installing LED light strips;

[0008] The wiring of the frame-type wardrobe lighting system is as follows: after passing through the transformer, the wires pass through the wall track and wire clips, through the cavity of the corresponding hollow suspended ceiling support device, and then from the suspended ceiling support device to the corresponding hollow column, where the wires are connected to the LED light strip on the corresponding column.

[0009] The wiring space for the lighting system is reserved in the wall rails, the floating support device, and the hollow columns, making the wiring more concealed, the whole wardrobe more beautiful, practical, and applicable to a wider range of situations, more convenient and safer.

[0010] In a preferred embodiment, the LED light strip is equipped with a diffuser cover, which is also embedded in the light groove of the column.

[0011] The built-in diffuser lampshade enhances the overall appearance and improves the lighting effect.

[0012] In the preferred embodiment, the wall track is L-shaped.

[0013] In a preferred embodiment, the LED light strip's light groove is formed on the non-mounting surface of the column, and the non-mounting surface of the column is curved. Mounting it on a non-mounting surface ensures it doesn't interfere with the overall installation of the wardrobe, while the curved surface also improves the wardrobe's streamlined shape, making it more aesthetically pleasing and sophisticated.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] Existing metal wardrobes lack lighting systems, requiring external lighting for proper use in poorly lit environments, thus limiting their usability. In contrast, this new frame-type wardrobe incorporates pre-installed wiring space for a lighting system in its wall-mounted rails, suspended support structure, and hollow columns. This lighting system enhances the wardrobe's aesthetics, practicality, applicability, convenience, and safety.

[0016] In summary, this frame-type wardrobe lighting system achieves standardized wardrobe modules, good disassembly between components, high efficiency in installation or adjustment, good environmental performance, high safety and reliability, good aesthetics, low cost, and helps save construction costs, improve construction efficiency, and reduce the labor intensity of lighting wiring construction.

The wardrobe leveling feet 30 also include foot positioning pieces 36, which can be locked to the ground with self-tapping screws, and can be threadedly installed and fixed with the second housing 32 (of course, in other embodiments, the foot positioning pieces can also be fixed with the second housing in other ways).

[0051] The quick-release connecting device 4 includes a quick-release buckle housing 41, two quick-release buckle steel hooks 42, a quick-release buckle eccentric lock 43, and a quick-release buckle shaft 44. The quick-release buckle eccentric lock 43 is rotatably mounted on the quick-release buckle housing 41 via the quick-release buckle shaft 44. The quick-release buckle housing 41 has mounting grooves 410 on both sides to accommodate the quick-release buckle steel hooks 42, and the two quick-release buckle steel hooks 42 are fixedly embedded in the mounting grooves 410 of the quick-release buckle housing 41 via the quick-release buckle shaft 44.

[0052] The storage mechanism is detachably connected to the column 1 via quick-release connecting device 4 as follows:

[0053] The connecting parts 95 of the storage mechanism (e.g., the connecting part of the clothes rod 91 is the clothes rod arm 95) are respectively provided with clearance spaces 950 for the quick-release buckle steel hooks 42 to pass through (it may also be a space or a through hole for the steel hooks 42 to pass through; for example, when the connecting part of the clothes rod 91 is the clothes rod arm 95, it is a clearance space; if it is the connecting part of a double or single movable drawer, the clearance space 950 may be a through hole); in this embodiment, the connecting parts of the storage mechanism 95 (for example, the connecting part of the clothes rod 91 is the clothes rod support arm 95) respectively have lock holes 951 that cooperate with the quick-release buckle eccentric lock 43 (the overall locking principle of the quick-release buckle eccentric lock is to use the eccentric mechanism to compress the elastic material and lock the storage mechanism through greater friction. In the preferred embodiment, the cooperation between the locking part and the lock hole is added, which is a secondary safety protection setting to prevent the storage mechanism from falling due to the failure of the elastic compression or human error).

[0054] When locking is required, the corresponding quick-release buckle steel hooks 42 pass through the clearance space 950 on the connecting part of the corresponding storage mechanism and hang on the mounting hole 104 of the steel adjusting strip 102 of the column 1. The corresponding quick-release buckle eccentric lock 43 is flipped so that the quick-release buckle eccentric lock 43 presses the connecting part of the corresponding storage mechanism, thus fixing the corresponding storage mechanism to the column 1.

[0055] When unlocking is required, flip the corresponding quick-release buckle eccentric lock 43 to disengage it from the connecting part of the corresponding storage mechanism, and remove the corresponding quick-release buckle steel hook 42 from the mounting hole 104 of the steel adjusting strip 102 of the column 1 to complete the unlocking.

[0056] The connecting component 95 of the storage mechanism has a multi-layer structure, wherein the layer closest to the column is an elastic material layer 952, and the other layers are rigid material layers 953.

[0057] The quick-release eccentric lock 43 is generally in the shape of a flat shell, with a locking part 431 at the top. This locking part is generally in the shape of an eccentric shaft, and a protruding locking part 432 is provided on the eccentric shaft 431. By rotating the quick-release eccentric lock 43, the locking part 432 can engage or disengage with the lock hole 951 on the component to be connected. (The overall locking principle of the quick-release eccentric lock is to use the eccentric mechanism to compress the elastic material, thereby locking the storage mechanism through greater friction. The addition of the locking part and the lock hole in this solution is a secondary safety protection feature, which prevents the storage mechanism from falling due to failure of the elastic compression or human error.)

[0058] In this embodiment, as Figure 26As shown, the frame-type wardrobe is equipped with a lighting system. The wiring conduit for the lighting system consists of the following components: the wall track 3 is L-shaped (the wall track 3 and transformer 302 are fixed to the wall 303), the wire clips 20 are clipped onto the top plate 2 and the L-shaped wall track 3, and the wiring 301 of the entire lighting system runs from the L-shaped wall track 3, through the wire clips 20, to the corresponding suspended top plate support device 5 (the corresponding suspended top plate support device 5 can be a hollow structure for wiring), then from the suspended top plate support device 5 to the corresponding hollow column 1, and then from the column 1 to the LED light strip 105 on the column 1. Each LED light strip 106 is equipped with a diffuser cover 106.
