Description

Technical Field

[0001] This utility model relates to the field of folding bed technology, specifically to a multi-position sleeping folding bed. Background Technology

[0002] A folding bed is a compact bed that can be folded down to reduce its size significantly. It combines practicality and portability and is widely used for temporary rest, in situations with limited space, or in outdoor environments.

[0003] Existing folding beds, due to their structural limitations, can only be used horizontally as a lying bed or folded down at the waist to function as a chair. While these functions are acceptable, some users experience increased leg fatigue when lying flat because the blood and lymph fluid accumulated in the lower limbs cannot return properly. Additionally, users with varicose veins are prone to leg edema when lying flat due to slower blood return. Therefore, existing folding beds still have shortcomings in their use.

[0004] In conclusion, it is necessary to invent a folding bed with multiple sleeping positions. Utility Model Content

[0005] Therefore, this utility model provides a multi-position sleeping folding bed to solve the problem that some users experience increased leg fatigue when lying flat because the blood and lymph fluid accumulated in their lower limbs cannot flow back properly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-position sleeping folding bed, including a headrest, a lumbar support, and a leg and foot area, wherein the headrest, lumbar support, and leg and foot area are connected and fixed by a connecting mechanism;

[0007] The connecting mechanism includes a hinged connecting seat and a hinged connecting block. The headrest and the lumbar support are hinged together by the hinged connecting seat, and the lumbar support and the leg and foot support are rotatably connected by the hinged connecting block.

[0008] Preferably, the bottom of the outer wall of the headrest is provided with a first U-shaped support rod, and the front and rear sides of the outer wall of the headrest are connected to the two ends of the first U-shaped support rod through connecting clamps. The front and rear sides of the outer wall of the first U-shaped support rod are connected with folded reinforcing ribs.

[0009] Preferably, the folded reinforcing rib is hinged to one end of the first U-shaped support rod near the headrest, and the other end of the folded reinforcing rib is hinged to the corresponding positions at the front and rear ends of the outer wall of the headrest.

[0010] Preferably, the outer wall of the lumbar support is provided with a second U-shaped support rod and a third U-shaped support rod at both ends, and the upper ends of the second U-shaped support rod and the third U-shaped support rod are connected to the outer wall of the lumbar support through connecting clamps.

[0011] Preferably, a fourth U-shaped support rod is provided below the bottom of the outer wall of the leg and foot part for support, and cross rods are provided at the front and rear ends of the outer wall on the opposite side of the leg and foot part and the fourth U-shaped support rod, and the cross rods are arranged in a cross manner.

[0012] Preferably, the ends of two adjacent cross rods are fixed to the corresponding positions of the legs and the outer wall of the fourth U-shaped support rod via fixing sleeves, and the bottom end of the other cross rod is slidably connected to the outer wall of the fourth U-shaped support rod via a first movable sliding sleeve.

[0013] Preferably, a positioning rack is fixed to the bottom end of the outer wall of the leg and foot part and the side near the waist support part, and the upper end of the other cross rod and the position corresponding to the positioning rack are slidably connected to the outer wall of the leg and foot part through the second movable sliding sleeve.

[0023] See attached document Figures 1-4 This utility model provides a multi-position folding bed, including a headrest 100, a lumbar support 200, and a leg and foot area 300. The headrest 100, lumbar support 200, and leg and foot area 300 are connected and fixed by a connecting mechanism. The headrest 100, lumbar support 200, and leg and foot area 300 can respectively support the head, back, and legs of a person. The connecting mechanism includes a hinged connecting seat 220 and a hinged connecting block 240. The headrest 100 and lumbar support 200 are hinged together by the hinged connecting seat 220. The hinged connecting seat 220 is designed to allow rotation between the headrest 100 and lumbar support 200 while connecting them. The lumbar support 200 and leg and foot area 300 are rotatably connected by the hinged connecting block 240. A first U-shaped support rod 110 is provided at the bottom of the outer wall of the headrest 100. The front and rear sides of the outer wall of the headrest 100 are connected to both ends of the first U-shaped support rod 110 via connecting clamps 130. The front and rear sides of the outer wall of the first U-shaped support rod 110 are connected with folding reinforcing ribs 120. The folding reinforcing ribs 120 are hinged to one end of the first U-shaped support rod 110 near the headrest 100, and the other end of the folding reinforcing ribs 120 are hinged to the corresponding positions of the front and rear ends of the outer wall of the headrest 100. The first U-shaped support rod 110 is provided to support the bottom part of the headrest 100 when the folding bed is laid flat and unfolded. The connecting clamps 130 can connect the first U-shaped support rod 110 to the headrest 100 and also allow the first U-shaped support rod 110 to rotate and fold as needed. The folding reinforcing ribs 120 are provided to improve the connection stability between the headrest 100 and the first U-shaped support rod 110 after unfolding.

[0024] The outer walls of the lumbar support 200 are equipped with second U-shaped support rods 210 and third U-shaped support rods 230 at both ends. The upper ends of the second U-shaped support rods 210 and 230 are connected to both ends of the outer walls of the lumbar support 200 via connecting clamps 130. The second U-shaped support rods 210 and 230 serve the same function as the first U-shaped support rod 110: to support the lumbar support 200 when the folding bed is unfolded. The sides of the second U-shaped support rods 210 and 230 are also fitted with folding clips. To enhance stability, a reinforcing rib (120) is used. A fourth U-shaped support rod (400) is installed at the bottom of the outer wall of the leg section (300). Crossbars (310) are installed at the front and rear ends of the outer wall on opposite sides of the leg section (300) and the fourth U-shaped support rod (400). These crossbars (310) are arranged in a crisscross pattern to support both the leg section (300) and the fourth U-shaped support rod (400). The fourth U-shaped support rod (400) supports the leg section (300) when extended. The height of the leg section (300) can be adjusted by changing the angle of the crossbars (310). The position is adjusted so that the leg section 300 can be raised to support the user's legs when needed. The ends of the two adjacent cross bars 310 are fixed to the corresponding positions on the outer walls of the leg section 300 and the fourth U-shaped support rod 400 via fixing sleeves. The bottom end of the other cross bar 310 is slidably connected to the outer wall of the fourth U-shaped support rod 400 via a first movable sliding sleeve. A positioning rack 330 is fixed to the bottom end of the outer wall of the leg section 300 and the side near the waist support 200. The upper end of the other cross bar 310 and the position corresponding to the positioning rack 330 are connected to the leg section 300 via a second movable sliding sleeve. The outer wall of the crossbar 310 is slidably connected, and the movable sliding sleeve is designed to allow the two crossbars 310 to slide on the outer wall of the leg part 300 and the fourth U-shaped support rod 400 at the end near the waist support 200. The second movable sliding sleeve has a sleeve shaft at the position corresponding to the serration at the bottom of the positioning rack 330. The sleeve shaft engages with the serration of the positioning rack 330. A reinforcing shaft 320 for support is provided at the center of the cross end of the crossbar 310. The sleeve shaft allows the position of the serration end of the positioning rack 330 to be adjusted up and down, which makes it convenient for personnel to adjust the cross angle of the crossbar 310.

[0025] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device according to the above description, then connect all electrical equipment to an external power supply, and control the operation of the device through an external controller. The control programs of all electrical equipment are edited by the production personnel in advance before production. This utility model does not make any technical improvements here, but only assumes that it can normally meet the needs of personnel.

[0026] Specifically, when using the chair, the headrest 100 and lumbar support 200 can be laid flat and unfolded. Then, the first U-shaped support rod 110, the second U-shaped support rod 210, and the third U-shaped support rod 230 can be unfolded to support the bottom of the headrest 100 and lumbar support 200. At the same time, the connecting ends of the first U-shaped support rod 110, the second U-shaped support rod 210, and the third U-shaped support rod 230 need to have a certain amount of friction to improve the stability of the headrest 100, lumbar support 200, first U-shaped support rod 110, second U-shaped support rod 210, and third U-shaped support rod 230 after unfolding. The user can also adjust the opening angle of the cross rod 310 so that the bottom of the fourth U-shaped support rod 400 is flush with the bottom of the second U-shaped support rod 210, so that the user can lie on the folding chair to rest.

[0027] Alternatively, the user can flip the headrest 100 upwards, which will support the user's back. At the same time, the angle of the cross bar 310 can be adjusted, causing the hinge block 240 to deform. The height of the leg support 300 can then be adjusted upwards, allowing the leg support 300 to horizontally elevate and support the user's legs. This can accelerate the return of blood and lymph fluid, thereby improving the user's comfort when lying down.

[0028] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
