Description

Technical Field

[0001] This invention relates to the field of apartment bed technology, and in particular to a steel apartment bed with a folding ladder linkage and concealed storage. Background Technology

[0002] As a comprehensive piece of furniture integrating sleep, study, and storage functions, dormitory beds are widely used in collective living scenarios such as school dormitories, corporate employee apartments, and youth hostels due to their advantages of saving space and having a neat layout. Among them, steel dormitory beds have become the mainstream choice for collective living environments due to their sturdy structure and high durability. However, existing products still have significant technical defects in terms of space utilization and functional integration, making it difficult to meet users' dual needs for convenient storage and compact space.

[0003] Traditional steel dormitory beds typically use ladders that are rigidly connected to the bed frame via welding or bolts, forming an inseparable integral structure. When not in use, these fixed ladders still obstruct the side or center of the bed, reducing the passage width of the study or activity area under the bed. This not only affects the user's freedom of movement but also creates a sense of visual congestion, making the already cramped living space feel even more cramped. While some products use folding ladders, the folding and unfolding of these ladders is not convenient enough, requiring users to spend a lot of time and effort, thus reducing the ease of use. Therefore, we propose a steel dormitory bed with a folding ladder-linked hidden storage design. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a folding ladder-linked hidden storage steel dormitory bed. This solves the problem that the climbing ladder of traditional steel dormitory beds is mostly rigidly connected to the bed body by welding or bolting, forming an inseparable integral structure. When not in use, such a fixed ladder still obstructs the side or middle space of the bed body, which reduces the passage width of the study area and activity area under the bed. This not only affects the user's freedom of movement, but also easily creates a visual sense of congestion, making the already compact living space even more cramped. Although some products adopt a folding ladder design, the folding and unfolding operation of the folding ladder is not convenient enough, requiring users to spend more time and effort, which reduces the convenience of use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a folding ladder-linked concealed storage steel dormitory bed, comprising: The steel dormitory bed and ladder mounting plate are fixedly connected to one side of the steel dormitory bed. A sliding base plate is fixedly connected to one side of the ladder mounting plate, and a folding ladder storage structure is provided on the sliding base plate.

[0022] Please see Figure 1-8 This invention provides a technical solution: a folding ladder-linked concealed storage steel apartment bed, comprising: A steel dormitory bed 1 and a ladder mounting plate 2 are fixedly connected to one side of the steel dormitory bed 1. A sliding base plate 7 is fixedly connected to one side of the ladder mounting plate 2, and a folding ladder storage structure is provided on the sliding base plate 7. The folding ladder storage structure includes storage ladder 1 (3), storage ladder 2 (4), storage ladder 3 (5), stepper motor 18, and storage ladder 4 (6). Storage ladder 4 (6) is fixedly connected to the side of the ladder mounting plate 2 near the sliding base plate 7. Storage ladder 3 (5) is slidably installed at the bottom of storage ladder 4 (6). Storage ladder 2 (4) is slidably installed at the bottom of storage ladder 3 (5). Storage ladder 1 (3) is slidably installed at the bottom of storage ladder 2 (4). Four moving wheels 25 are fixedly connected to the bottom of storage ladder 1 (3). Two sliding grooves 17 are opened at the top of the sliding base plate 7. The four moving wheels 25 are respectively rotatably connected to the inner bottom wall of the corresponding sliding groove 17. A transmission groove 23 is opened at the bottom of storage ladder 1 (3). Two fixed plates 19 are fixedly connected to the inner bottom wall of storage ladder 1 (3). Gears 20 are rotatably connected to the opposite surfaces of the two fixed plates 19. The gears 20 are located inside the transmission groove 23. Stepper motor 18 is fixedly installed on one side of the corresponding fixed plate 19. The output end of stepper motor 18 rotates through the corresponding fixed plate 19 and is fixedly connected to the gear 20.

[0023] The folding ladder storage structure also includes a toothed plate 22. A groove 21 is provided on the top of the sliding base plate 7. The toothed plate 22 is fixedly connected to the inner bottom wall of the groove 21. The gear 20 meshes with the toothed plate 22. Slide rails 15 are fixedly connected to both sides of the storage ladder 2 4, storage ladder 3 5, and storage ladder 4 6 respectively. Linkage plates 14 are fixedly connected to both sides of the storage ladder 1 3, storage ladder 2 4, and storage ladder 3 5 respectively. Sliding sliders 16 are slidably connected inside the six slide rails 15 respectively. The six sliders 16 are fixedly connected to the corresponding linkage plates 14 respectively.

[0024] Storage ladder 3 5 has two long support plates 12 fixedly connected to one side of the ladder mounting plate 2, and storage ladder 2 4 has two short support plates 13 fixedly connected to one side of the ladder mounting plate 2. The bottom ends of the two long support plates 12 and the two short support plates 13 are respectively rotatably connected to rollers 24, and the four rollers 24 are respectively rotatably connected to the top of the sliding base plate 7.

[0025] A storage cavity 9 is provided on the side of the ladder mounting plate 2 near the storage ladder 3. Two long support plates 12 and two short support plates 13 are respectively adapted to the interior of the storage cavity 9. Storage doors 8 are hinged to one side of the storage ladder 3, storage ladder 4, storage ladder 5 and storage ladder 6 respectively. A partition 10 is bolted inside the storage ladder 3. A control button 11 is fixedly installed on the side of the storage ladder 3 away from the steel dormitory bed 1. The slider 16 has an "L" shaped structure. A study table is installed under the steel dormitory bed 1.

[0026] Furthermore, when using the device, pressing the control button 11 fixedly installed on the side of the storage ladder 3 away from the steel dormitory bed 1 starts the stepper motor 18. The stepper motor 18 is fixedly installed on one side of one of the two fixed plates 19 on the inner bottom wall of the storage ladder 3. Its output end rotates through the corresponding fixed plate 19 and is fixedly connected to the gear 20 located inside the transmission groove 23. The stepper motor 18 drives the gear 20 to rotate. Since the gear 20 is meshed with the toothed plate 22 fixedly connected to the bottom wall of the groove 21 at the top of the sliding base plate 7, the gear 20 will move along the toothed plate 22 during rotation, thereby driving the storage ladder 3 to roll outward in the two sliding grooves 17 opened at the top of the sliding base plate 7 through the four moving wheels 25 fixedly connected to its bottom.

[0027] When storage ladder 13 moves, the linkage plates 14 fixedly connected to both sides will drive the corresponding sliders 16 to slide inside the corresponding slide rails 15, thereby sequentially driving storage ladder 24 and storage ladder 35 to slide away from the ladder mounting plate 2. The two long support plates 12 fixedly connected to the side of storage ladder 35 near the ladder mounting plate 2 and the two short support plates 13 fixedly connected to the side of storage ladder 24 near the ladder mounting plate 2, with the rollers 24 rotatably connected to their bottom ends, will roll on the top of the sliding base plate 7 to assist in support and movement, so that the entire folding ladder slides smoothly, allowing users to climb onto the steel dormitory bed 1.

[0028] When the folding ladder needs to be stored, press the control button 11 again. The stepper motor 18 rotates in the reverse direction, driving the gear 20 to rotate in the reverse direction. The gear 20 moves in the reverse direction along the toothed plate 22, so that the storage ladder 3 moves towards the ladder mounting plate 2 through the sliding wheel 25 in the slide groove 17. During the movement of the storage ladder 3, the linkage plate 14 and the slider 16 drive the storage ladder 4 and the storage ladder 5 to slide inward in sequence and store them. Finally, the two long support plates 12 and the two short support plates 13 will be stored in the storage cavity 9 opened on the side of the ladder mounting plate 2 near the storage ladder 3, realizing the hidden storage of the folding ladder.

[0029] Storage doors 8 are hinged to one side of storage ladder 3, storage ladder 4, storage ladder 5, and storage ladder 6 respectively. Items can be stored inside by opening the storage doors 8. In addition, partitions 10 are installed inside storage ladder 3 by bolts, which can divide the internal space of storage ladder 3 into different areas, thereby isolating the transmission structure.

[0030] The stepper motor 18 drives the gear 20 and the toothed plate 22 to move the storage ladder 3, which in turn moves the storage ladder 4 and the storage ladder 5 in sequence. Finally, the two long support plates 12 and the two short support plates 13 are stored in the storage cavity 9 of the ladder mounting plate 2, realizing the hidden storage of the folding ladder. This saves space, effectively increases the passage width under the bed, enhances the openness and comfort of the living space, and avoids visual congestion.

[0031] During the unfolding and folding of the folding ladder, the storage ladder 3 rolls within the two grooves 17 of the sliding base plate 7 via four fixedly connected movable wheels 25 at the bottom. At the same time, the rollers 24 rotatably connected to the bottom ends of the support long plate 12 of the storage ladder 3 and the support short plate 13 of the storage ladder 4 roll on the top of the sliding base plate 7 to assist in support and movement, thereby reducing shaking and jamming and improving safety during use.
