Description

Technical Field

[0001] This application relates to the technical field of medical devices, and in particular to a foldable headboard mechanism for a nursing bed. Background Technology

[0002] In modern life, mobile beds are widely used in medical, rehabilitation, and nursing fields, frequently moving between wards, elevators, examination rooms, homes, and rehabilitation centers. Traditional beds have fixed headboards. When moving these beds to different locations, especially in narrow passageways and elevators, it is often necessary to disassemble parts of the bed for easy transport and reinstallation at the new location, or to transport the bed components directly to the site for installation. With the accelerating development of a global aging society and the continuous advancement of medical and rehabilitation bed technology, higher demands are placed on bed functionality. Users not only require reliable headboard protection and safety but also expect the bed to be easier and quicker to navigate through narrow areas such as elevators and doorways, reducing unnecessary disassembly and reassembly. Therefore, there is an urgent need for a flexible and easy-to-operate bed design to address the accessibility issues of traditional beds when moving them into homes.

[0003] Regarding the aforementioned technologies, the inventors believe that existing load-bearing beds have difficulties turning in narrow aisles and entering residential building elevators. Most beds on the market are about 2 meters long, while ordinary elevators are usually about 1.5 meters deep. The design of the beds themselves has limitations, resulting in high delivery and installation costs and affecting the production efficiency of enterprises. Therefore, in order to solve the above problems, this application provides a foldable nursing bed headboard mechanism. Utility Model Content

[0004] To address the problems mentioned in the background art, this application provides a foldable nursing bed headboard mechanism.

[0005] This application provides a foldable nursing bed headboard mechanism, including a movable headboard frame, a headboard fixing hook, a Torx handle screw, a headboard board, a headboard connecting plate, a locking plate, a first pivot screw, and a second pivot screw. The movable headboard frame is a symmetrical structure welded from square steel tubes. Each side of the square tube is welded with a shaped steel sheet with a pin hole and a threaded hole, and the tail end is welded with a rectangular steel plate with two threaded holes. The headboard fixing hook has one threaded hole, one pin hole, and one mating surface A. The headboard board is made of wood, 30mm thick, and has Velcro. There are two headboard connecting plates, symmetrically arranged, with a hook mating surface B and a closed surface C below. A fixing pin is provided between mating surfaces B and C, and an installation hole is provided in the middle. The locking plate has a hook and a pin hole in the middle.

[0006] Preferably, the movable headboard frame is rotatably connected to the pin hole on the outer frame via the pin hole on the irregular steel sheet, and two second axial screws are installed in the two threaded holes on the rectangular steel plate at the tail end of the movable headboard frame.

[0007] Preferably, one end of the pin hole of the headboard fixing hook is rotatably connected to the lower threaded hole of the outer frame through the lower first shaft screw, and half of the plum blossom handle screw is screwed into one end of the threaded hole of the headboard fixing hook.

[0008] Preferably, the insertion hole of the insert locking piece is rotatably connected to the fixing pin on the headboard connecting plate, and the headboard connecting plate is fixed to the headboard by screws.

[0009] In summary, this application includes the following beneficial technical effects:

[0010] 1. Improved mobility in narrow areas, solving transfer difficulties: Compared to traditional fixed-head nursing beds, this mechanism allows the headboard to be folded up. Folding it down involves simply loosening the Torx handle screws and unlocking the locking plate, allowing the headboard to fold against the backrest, significantly shortening the overall length of the bed. This allows for easy passage through narrow aisles, apartment building elevators, and other areas, avoiding the hassle of partial or complete disassembly of traditional beds, effectively solving the mobility issues for entry and transfer.

[0011] 2. Reduce delivery and installation costs, improve enterprise efficiency, and broaden the application range of rehabilitation and medical care beds: Since the bed can be easily transferred without disassembling the headboard, it reduces the disassembly and assembly process of traditional beds during delivery and installation, reduces labor costs and component damage risks caused by disassembly and assembly, and avoids the inefficiency caused by disassembly and assembly, which helps to improve the production and operation efficiency of enterprises.

[0012] 3. Simple and efficient operation, no complicated tools required: The locking and unlocking of the mechanism relies on components such as the Torx handle screw and the locking plate. No professional tools are required during operation. Simply move the locking plate and turn the Torx handle screw to lock or unlock. The steps for folding and resetting the headboard are clear and intuitive, which users can quickly master, reducing the operational threshold during transfer and adjustment.

[0013] 4. Ensuring safety and stability during use: Under normal use, the headboard is securely fixed by multiple locking mechanisms, including the mating surface of the headboard hooks and the engagement of the shaft screws, the tightening of the Torx handle screws, and the locking plate locking the headboard. This ensures the headboard is firmly fixed and prevents loosening or shaking during use, meeting the user's needs for headboard protection and safety. When folded, the headboard is attached to the backrest with Velcro, which also ensures stability after folding. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0020] Example 1:

[0021] A foldable nursing bed headboard mechanism, as described in reference Figure 1 - Figure 4 The headboard includes a movable headboard frame 1, a fixed headboard hook 2, a Torx handle screw 3, a headboard board 4, a headboard connecting plate 5, a locking plate 6, a first pivot screw 7, and a second pivot screw 8. The movable headboard frame 1 is a symmetrical structure welded from square steel tubes. Each side of the square tube is welded with a shaped steel sheet with a pin hole and a threaded hole, and the tail end is welded with a rectangular steel plate with two threaded holes. The fixed headboard hook 2 has one threaded hole, one pin hole, and one mating surface A. The headboard board 4 is made of wood, 30mm thick, and has Velcro fasteners. There are two headboard connecting plates 5, symmetrically arranged, each with a hook mating surface B and a closed surface C below. A fixing pin is provided between mating surfaces B and C, and an installation hole is provided in the middle. The locking plate 6 has a hook and a pin hole in the middle.

[0022] Reference Figure 4 The movable headboard frame 1 is rotatably connected to the pin hole on the outer frame through the pin hole on the irregular steel sheet.
