[0031] Example 1

[0032] like Figures 5 to 8 The first embodiment of a hidden bed ladder of the utility model is shown, which includes a ladder 2 and a connecting part 7. One side of the ladder 2 can be fixed to the fixing frame 3 beside the ladder 2 through a detachable connecting structure, and the other side of the ladder 2 is hinged to the connecting part 7 through a hinge structure. When the connecting structure is disassembled, the ladder 2 can be rotated to a position parallel to the connecting part 7 through the hinge structure, and can be moved to the hidden space 11 beside the ladder 2 with the connecting part 7. This setting method can realize the push-pull, rotation, opening and closing of the ladder 2, thereby realizing the ladder 2 being hidden in the hidden space 11 or realizing the use of the ladder 2, that is, when the ladder 2 is not needed, the ladder 2 can be moved and hidden in the hidden space 11, so as to save the ground space and prevent the user from being accidentally bumped and injured when moving on the ground. Further, the connecting part 7 can be set in the cabinet 1, or in the gap beside the cabinet 1, and the hidden space 11 is the cabinet 1 placed beside the bed frame 3 or the gap beside the cabinet 1, so as to realize the hiding effect of the ladder 2 and the dustproof effect.

[0033] The ladder 2 includes a fixed portion 4, a treading portion 6 and a supporting portion 5. One end of the fixed portion 4 is detachably connected to the top of the treading portion 6, and the other end of the fixed portion 4 is detachably connected to the fixing frame 3. The treading portion 6 includes a support 61 and a step 62. The support 61 is two. The two ends of the step 62 are respectively connected to the two support 61. The step 62 and the support 61 are welded, and the top of the support 61 is plugged into the fixed portion 4. The supporting portion 5 is arranged at the bottom end of the treading portion 6 and is a U-shaped structure. The two open ends of the U-shaped structure of the supporting portion 5 are connected to the support on the hidden space 11. The upper end of the fixing part 4 is a hook-shaped structure with a hook, and the end of the fixing part 4 with a hook can be easily hung with the fixing frame 3, and the lower end thereof is a cylindrical design, which can be plugged into the pillar 61. When the fixing part 4 is not in use, it is plugged into the pillar 61. When the fixing part 4 is needed to be fixed, it only needs to be lifted up from the pillar 61 to a certain height, that is, the hook head of the hook-shaped structure is higher than the fixing frame 3, and the hook tail is lower than the fixing frame 3, and the ladder 2 is pushed to the second direction. The fixing frame 3 and the fixing part 4 overlap in the vertical direction. The fixing part 4 can be hung on the fixing frame 3 by pressing the fixing part 4 downward. In addition, the fixing part 4 can be removed from the fixing frame 3 by simply reversing the operation. By hanging, the fixing part 4 can be easily added or removed, providing flexibility in design and function without disassembling the entire ladder 2. Furthermore, the lower end of the fixing part 4 is plugged into the support 61 throughout the entire process. The use of hanging for fixing between the fixing part 4 and the fixing frame 3 in this embodiment does not mean that only hanging can be used. In addition, the fixing part 4 and the fixing frame (3) can also be fixed by a slot structure, a latch structure, etc., which should be selected according to actual conditions. The rungs 62 and the support 61 of the ladder 2 are welded, and the welding points can evenly disperse the force, so that the ladder 2 has a better bearing capacity. At the same time, there is no gap at the welding point, which can reduce the intrusion of moisture and corrosive media, making the welded ladder 2 more corrosion-resistant and wear-resistant than the ladder 2 connected by bolts. The absence of exposed bolts and nuts also makes the appearance of the ladder 2 more neat and beautiful, ensuring that the user is not easily scratched by the ladder 2 when climbing the ladder 2.The upper end of the fixing part 4 is a hook-shaped structure with a hook at one end. The end of the fixing part 4 with the hook is hung with the fixing frame 3, and the other end is inserted into the slot provided at the top of the pillar 61 or the top of the pillar 61 is inserted into the slot provided at the other end of the fixing part 4. The hanging method can achieve rapid connection or disconnection without additional tools, which is convenient for quick operation. For users, the hanging method is simple and intuitive, easy to understand and use. At the same time, the simple structure of the fixing part 4 does not require a complicated manufacturing process and has low cost; the plug-in method can allow the fixing part 4 and the pillar 61 to be partially or completely separated, so it is convenient for transportation and storage, saving space, and a properly designed plug-in method is convenient for modular design and inspection and maintenance. Each component can be manufactured or replaced independently, which is convenient for maintenance and upgrading. At the same time, the plug-in method reduces the dependence on materials such as screws and glue, and can be disassembled and reassembled many times, increasing the reusability of components.

[0034] As an embodiment of the present invention, the ladder 2 can be moved in the first direction or the second direction through the connecting portion 7, that is, the opening direction of the cabinet 1 is the first direction, and the second direction is arranged opposite to the first direction. The steps 62 on the ladder 2 include a first end and a second end opposite to each other in the first direction, that is, when the ladder 2 and the connecting portion 7 are hidden in the hidden space 11, the steps 62 include a first end close to the first direction and a second end away from the first direction; the steps 62 of the ladder 2 overlap with the mirror 71 in parallel and are embedded in the hidden space 11, which is the first state of the ladder 2, that is, the ladder 2 and the mirror 71 are both hidden states, and the hidden space 11 is the cabinet or the gap beside the cabinet. Furthermore, the connecting portion can be arranged in a separate hidden cabinet to achieve the hiding effect of the ladder 1. The hideable design allows the ladder 2 and the mirror 71 to be quickly and conveniently folded up when not in use, which not only greatly saves ground space, but also prevents dust accumulation, reduces interference with other people's activities, avoids accidental collisions of users, and thereby reduces the risk of user injury.

[0035] Example 2

[0036] like Figures 1 to 3The second embodiment of a hidden bed ladder of the utility model is shown. This embodiment is similar to the first embodiment, except that this embodiment describes the ladder 2 changing from the first state to the second state. A handle 21 for pushing and pulling is provided on the first end support 61 of the ladder 2. Pulling the handle 21 causes the ladder 2 to move along the first direction through the connecting portion 7. The ladder 2 moves to the first position, that is, the second end of the ladder 2 is located at the edge of the fixing frame 3. The second end of the ladder 2 rotates around the axis through the connecting portion 7, that is, rotates around the support 61 close to the connecting portion 7. When the ladder 2 step 62 is rotated to be parallel to the fixing frame 3, the ladder 2 step 62 is kept perpendicular to the first direction to move the ladder 2 along the second direction. When the step 62 of the ladder 2 is parallel to the fixing frame 3, which is the second position, the fixing portion 4 inserted on the pillar 61 is hung on the fixing frame 3, and the supporting portion 5 is in contact with the supporting member 101 of the hidden space 11, and the supporting member 101 is the cabinet door of the cabinet body 1, thereby achieving the fixation of the ladder 2, which is the second state of the ladder 2, that is, the use state of the ladder 2. At this time, the upper end of the ladder 2 is fixed to the fixing frame 3 by the fixing portion 4, and the lower end is supported by the supporting portion 5. The setting and use of the fixing portion 4 and the supporting portion 5 can not only reduce the risk of shaking and tilting when the user uses the ladder 2 and increase stability, but also the supporting portion 5 can prevent the ladder 2 from sliding on a smooth ground to a certain extent, thereby ensuring the safety of personnel.

[0037] The steps 62 of the ladder 2 of the present invention are provided with an anti-skid structure. The anti-skid structure increases the friction between the user's feet and the steps 62 by increasing the friction between the contact surfaces, which can reduce the risk of the user slipping and falling, especially in a humid environment or when the user's feet are wet, which helps the user to stay stable when climbing the ladder 2. In dormitories, which are scenarios where the ladder 2 needs to be used frequently, the anti-skid structure can increase the user's confidence, provide a more comfortable experience for them, and reduce the discomfort caused by foot sliding. The ladder 2 is made of iron material, which has high strength and good durability, can withstand a large weight, and is suitable for use as a load-bearing ladder. At the same time, the iron material has low cost and is affordable. It is easy to process into various shapes and sizes to meet different usage requirements. At the same time, the scrapped iron ladder can be recycled to reduce the impact on the environment. The iron ladder can be coated or plated to prevent rust. Through proper maintenance and use, the iron ladder can become a durable and economical tool. The use of iron material for the ladder 2 in this embodiment does not mean that only iron material can be used. The specific choice needs to be determined according to the budget, frequency of use, durability and other requirements as well as the requirements of the specific environment. For example, if the environment is humid, stainless steel or aluminum alloy ladders may be preferred to ensure durability and corrosion resistance. Considering portability and cost, plastic or aluminum alloy ladders can also be selected.

[0038] Example 3

[0039] like Figure 3 to Figure 4The third embodiment of a hidden bed ladder of the utility model is shown. This embodiment is similar to the first embodiment, except that this embodiment describes the ladder 2 changing from the second state to the third state. In the second state, the ladder 2 removes the fixing part 4 from the fixing frame 3 and puts it back on the pillars 61 at both ends of the ladder 2, so that the ladder 2 can continue to move along the first direction through the connecting part 7. The ladder 2 is connected to the connecting part 7 and moves in the first direction to expose the mirror 71 to the cabinet 1. This is the third state of the ladder 2, that is, the state of using the mirror 71; the connecting part 7 includes a mirror 71, a hinge 72, a guide rail 73, and an outer frame bracket 74, and the mirror 71 is embedded in the outer frame bracket 74. The bed ladder in the third state allows the user to stand in front of the cabinet 1 and see his or her entire body from head to toe in front of the full-length mirror, which is convenient for checking clothing and tidying up appearance, allowing the user to adjust himself or herself to a better state in a convenient way. The mirror 71 is made of acrylic, which is lighter than glass, making it easier to carry and install. At the same time, the acrylic mirror is not easy to break. Even when it is subjected to strong impact, it will show cracks rather than fragments, reducing the risk of users accidentally bumping into the mirror 71 and causing cuts. The use of acrylic material for the mirror 71 in this embodiment does not mean that the material is limited to acrylic, and various usage factors can also be weighed to make a choice.

[0040] In this embodiment, the ladder 2 and the connecting part 7 are connected by a hinge 72 to ensure that the ladder 2 can be rotated and opened and closed. The hinge 72 provides a stable connection to ensure the relative positions of the connected parts while being able to withstand long-term repeated use, allowing relative connection movement between the connected parts and providing good flexibility. In this embodiment, the ladder 2 and the connecting part 7 are connected by a hinge structure, which does not mean that only hinges can be used. The specific choice needs to be determined according to budget requirements and the requirements of the specific environment.

[0041] In this embodiment, the connection part 7 and the fixed frame 3 are connected and transmitted through the guide rail 73. The guide rail 73 can provide smooth linear motion, thereby achieving precise position control and reducing friction and vibration. At the same time, the guide rail 73 is easy to maintain and only needs regular cleaning and lubrication to maintain normal use. The use of a guide rail for the connection between the connection part 7 and the fixed frame 3 in this embodiment does not mean that it is limited to a guide rail. A slide groove, a gear rack, etc. can also be used for transmission. The specific selection can be determined by considering the specific requirements of the application, such as load capacity, range of motion, accuracy, maintenance requirements and cost.

[0042] Example 4

[0043] like Figure 1The following is an embodiment of a multifunctional combined bed of the utility model. This embodiment is similar to the embodiment 1, except that it also includes a bed body installed beside the bed ladder, including a bed frame and a bed board 8. The fixed frame 3 is the bed frame in the bed body. The hidden space 11 is a cabinet 1 placed beside the bed frame or a gap beside the cabinet 1. Two cabinets 1 are installed between the two bed bodies. The bed ladder is installed between the two cabinets 1. A desk 10 is also provided on the side of the cabinet 1 away from the connecting portion 7. The end of the desk 10 close to the ladder 2 is flush with the end of the cabinet 1 or the end of the desk 10 close to the ladder 2 is retracted from the end of the cabinet 1, so that it looks beautiful while reducing the risk of users being bumped and injured. A drawer and a storage cabinet are provided on the side of the desk 10 close to the support column 9 for easy storage in different areas and classification, management and search. The drawer design can also protect the stored items from dust and moisture to a certain extent. At the same time, the desk 10 is provided with three layers at the end in the second direction. The storage cabinet and the three-layer storage cabinet are arranged with the back against the wall. The design of the upper bed and the lower table makes full use of the vertical space and combines the functions of sleeping, studying and working. The concealable ladder 2 further saves ground space and is suitable for environments with relatively tight space. The bed is arranged on the upper part, which can also reduce the impact of ground activities on the sleeper; further, the bed frame 3 is provided with anti-fall railings 31 at the head, foot and one side of the bed board 8, that is, the railing 31 is arranged on three sides. This arrangement is suitable for beds placed against the wall, which saves space and materials while providing necessary protection to prevent users from turning over or moving violently while sleeping and accidentally falling off the bed. At the same time, it prevents bedding from falling off the bed board 8 to a certain extent, reduces the anxiety of users at night due to fear of falling, and helps to improve the sleep quality of users. The three-side setting of the railing 31 in this embodiment does not mean that it is limited to the three-side setting. The design and installation of the railing 31 should comply with local safety standards and regulations.

[0044] Example 5

[0045] like Figures 1 to 6 Shown below is the fifth embodiment of a multifunctional combination bed of the utility model. This embodiment is similar to the first embodiment. A multifunctional combination bed is an independent unit and may include several independent units. When the number of independent units is two even numbers, every two independent units form a group, and the two independent units in the group are connected on the side close to the cabinet 1, and the two single-sided support columns 9 are located at the two far ends and are arranged oppositely; when the number of independent units is three odd numbers, two of the independent units form a group, and are connected on the side close to the cabinet 1, and the two single-sided support columns 9 are located at the two far ends and are arranged oppositely, and the side of the cabinet 1 of the third independent unit is placed close to the side wall, so that the ladder 2 and the connecting part 7 can be hidden in the gap between the cabinet 1 and the wall, thereby saving space and having a neat appearance.
