Description

Technical Field

[0001] The present invention relates to the technical field of apartment beds, in particular to an apartment bed with high space utilization. Background Art

[0002] An apartment bed is a design that utilizes vertical space. The sleeping area is usually raised to the upper level (similar to an upper bunk), while the lower level is completely freed up for other functions. The main core is "demanding space upwards" and is suitable for small apartments with sufficient ceiling height but limited space, rental housing, student apartments or children's rooms. It is widely used in modern space design. However, current apartment bed designs mostly adopt the design of upper bed with lower desk, upper bed with lower cabinet or bunk bed. When used, the space division is fixed. Although the space utilization rate is extended compared to current conventional beds, the fixed design leads to a certain waste of space utilization. For example, the design of upper bed with lower desk: although the upper level space is utilized, the table hole position of the table is idle when the table is not in use, and it can only meet the sleeping needs of the upper bed; upper bed with lower cabinet: this also can only meet the sleeping needs of the upper level and does not have the use of a desk; bunk bed: it meets the sleeping needs of upper and lower bunks, but there is no storage space or desk and office space, resulting in poor space utilization and unable to meet the needs of storage, office and double sleeping. Summary of the Invention

[0003] In order to overcome the technical defects of the existing technology, the present invention provides an apartment bed with high space utilization, which has the effect of adjusting the lower bed and the office position up and down. When sleeping, you sleep on the bunk bed. When working, the upper bed is used as a sleeping area and the lower position can be used as an office area, which is convenient for switching the space application status and improving space utilization.

[0004] The technical solution adopted by the present invention is: an apartment bed with high space utilization rate, comprising four symmetrically installed uprights, wherein the upper ends of the uprights are fixedly installed with an upper bed board, the lower ends of the uprights are fixedly installed with a table body assembly, a cabinet is fixedly installed between the uprights on one side, and a climbing frame is fixedly installed on one side of the upper bed board at a position opposite to the cabinet, a lower bed board is slidably installed between the uprights and below the upper bed board, a lifting platform is vertically slidably installed in the middle position of the table body assembly, the lifting platform is threadedly connected to the lower bed board, an adjusting component is installed on the lower surface of the lower bed board, the driving end of the adjusting component is located inside the cabinet, and the executing end of the adjusting component is fixedly connected to the lower bed board. When in use, the overall state can be adjusted according to usage requirements. When the upper bed and lower table state is used, the lower bed board is pulled up by the adjusting component, so that the distance between the lower bed board and the upper bed board is shortened. The lifting platform is slidably mounted on the table body assembly, and the lifting platform is threadedly connected to the lower bed board, thereby enabling the lower bed board to drive the lifting platform to rise so that the upper surface of the lifting platform and the upper surface of the table body assembly are in the same plane, which is convenient for working and studying on the lifting platform and the table body assembly, and the user can climb onto the upper bed board and sleep through the climbing frame, forming a configuration of an upper bed and a lower table. When a double bed is needed for sleeping, the lower bed board is lowered by the adjusting assembly, so that the distance between the lower bed board and the upper bed board is increased, and the lifting platform is lowered as the lower bed board is lowered, so as to prevent items placed on the lifting platform from being squeezed by the lower bed board, which is convenient for switching to a bunk bed state. The user can climb onto the upper bed board and the lower bed board and sleep through the climbing frame, and the table body assembly and the cabinet not only increase the storage space, but also facilitate the installation of the driving end in the adjusting assembly.

[0005] Preferably, a guide groove is vertically opened on the front and rear sides opposite to each other of the column, and guide blocks are fixedly installed on the four corners of the lower bed board. The guide blocks are slidably engaged inside the guide grooves, and the execution end of the adjustment assembly is fixedly connected to the upper surface of the guide blocks. Through the guide grooves and the guide blocks, the lower bed board is guided when it is raised and lowered along the column, and it is convenient to hide the steel cable in the adjustment assembly to avoid exposure of the steel cable.

[0006] Preferably, the height of the cabinet is higher than the height of the upper bed board, and a storage slot is provided on one side of the cabinet above the upper bed board, and a storage cavity is provided inside the cabinet at a lower end of the storage slot, the driving end of the adjustment component is located inside the storage cavity, and a through hole is provided on the side of the cabinet at one side of the storage cavity, the execution end of the adjustment component passes through the through hole and extends to the outside of the cabinet, and a control panel is fixedly installed on the front side of the cabinet at the position of the storage cavity, through which the hoist in the adjustment component and the servo motor in the lifting platform can be easily opened and closed, thereby facilitating operation. The hoist in the adjustment component can be easily stored and fixed through the storage cavity to avoid being exposed. The steel cable in the adjustment component passes through the through hole and extends to the outside of the cabinet, thereby facilitating adjustment of the height of the lower bed board and adjusting the overall shape to suit different application requirements. In addition, the storage slot improves the storage capacity above the upper bed board and improves space utilization.

[0007] Preferably, an upper guardrail is fixedly installed on one side of the upper bed board, and a plug-in slot is provided at the lower end of the upper guardrail, which is communicated with the lower end of the upper bed board. A lower guardrail is fixedly installed on one side of the lower bed board just below the plug-in slot, and the lower guardrail is consistent with the plug-in slot. The upper guardrail and the lower guardrail can be used to protect the edge positions of the upper and lower bed boards to avoid falling problems during sleep, and the lower guardrail can be plugged into the inside of the upper guardrail through the plug-in slot when the lower bed board is stored upward, thereby reducing the gap between the upper and lower bed boards and increasing the rising degree of the lower bed board.

[0008] Preferably, mattresses are placed on the upper surfaces of the upper bed board and the lower bed board, which are convenient for use during sleep. Reinforcing rods are fixedly installed in a vertical array on one side of the climbing frame. The climbing frame is in an inclined state. The other end of the reinforcing rod is fixedly connected to one of the columns. Hooks are sleeved on the reinforcing rods in an array. The reinforcing rods and the hooks improve the stability and firmness of the climbing frame, and facilitate the hanging and storage of miscellaneous items. It is convenient to utilize the gap between the climbing frame and the columns, thereby increasing space utilization.

[0009] The lifting platform is slidably connected to the sliding rails, and the lifting platform is convenient to lift and lower along the sliding rails, so that the lifting platform can be adjusted to the position of the hollow hole, and the side hollow cabinets and the storage cabinets are respectively fixedly installed on both sides of the lower surface of the table board, and the four corners of the table board, the side hollow cabinets and one side of the storage cabinet are fixedly connected to the column.

[0010] Preferably, the lifting platform includes a slide bar, which is slidably engaged with the slide rail, and an L-shaped bracket is fixedly installed between the slide bars, and a lifting plate is fixedly installed on the upper end of the bracket, and the lifting plate coincides with the hollow hole. A perforated plate is fixedly installed on one side of the upper end of the lifting plate, and a servo motor is fixedly installed below the middle position of the lifting plate, and a threaded rod is fixedly installed on the output end of the servo motor, and the upper end of the threaded rod extends above the lifting plate, and the threaded rod is located in the middle position of the rear side of the perforated plate, and the threaded rod is threadedly connected to the lower bed board, and the threaded rod is driven to rotate by the servo motor to facilitate the adjustment of the lifting plate and the lower bed. The distance between the boards increases the space for lowering the lower bed board, preventing the lifting board from touching the bottom when the lower bed board moves downward, and when the lower bed board rises to the position of the upper bed board, the servo motor is turned on in reverse to make the lifting board descend, and the upper surface of the lifting board is adjusted to the position of the table board. The upper surface of the lifting board and the table board are on the same horizontal plane, which is convenient for office work. When the lifting board is lifted or lowered, it moves along the slide rail through the slide bar, which not only improves the guidance during lifting or lowering, but also improves the load-bearing capacity of the lifting board through the bracket, and facilitates the hanging of some daily necessities through the perforated board, thereby increasing the utilization effect of space.

[0011] Preferably, an internal threaded tube is fixedly installed on the rear side of the middle position of the lower surface of the lower bed board, and the threaded rod is threadedly connected to the internal threaded tube. When the threaded rod rotates, the length of the threaded rod extending into the interior of the internal threaded tube is adjusted to facilitate adjustment of the distance between the lower bed board and the lifting plate.

[0012] Preferably, the adjustment assembly includes a steering pulley, a load-bearing pulley and a winch. The winch is fixedly installed inside the cabinet. Four steel cables are wound around the winch. One end of each of the steel cables passes through the steering pulley and the load-bearing pulley and is fixedly connected to the upper surface of the guide block. The winch reels in and unwinds the steel cables, so that the steel cables lift or lower the lower bed board. The steering pulley and the load-bearing pulley facilitate the adjustment of the direction of the steel cables, so that the lower bed board can be raised or lowered.

[0013] Preferably, the steering pulley and the load-bearing pulley are both fixedly mounted on the lower surface of the upper bed board, and the load-bearing pulley is located directly above the guide groove. Through the load-bearing pulley, the steel cable is conveniently located inside the guide groove, and the steel cable in the vertical direction is hidden to avoid exposure.

[0014] The beneficial effect of the present invention is that the height of the lower bed board is adjusted by the adjustment component. When the lower bed board is close to the lower part of the upper bed board, the lifting platform rises, and the surface of the lifting platform and the table board are on the same plane, forming a state of upper bed and lower table, and combined with the side hollow cabinets, storage cabinets and upright cabinets, a separate space distribution for sleeping, working and storage is formed.

[0015] By adjusting the components to lower the lower bed board, the lifting platform is simultaneously driven down. The lifting platform descends to the space at the lower end of the table body. The distance between the lower bed board and the upper bed board increases, forming a double-layer sleeping and storage space distribution, improving space utilization and the effect of flexible adjustment according to needs.

[0016] Through the matching perforated boards, hooks, side hollow cabinets and storage slots, the overall space has more space for storing small items, making use of small areas to form a three-dimensional space utilization effect, greatly avoiding space waste, and is suitable for use in households with sufficient ceiling height but limited area.
