Description
Technical Field
[0001] This utility model belongs to the technical field of in-home bathing assistance industry, and in particular relates to a manually adjustable and folding bathing bed. Background Technology
[0002] With the country's population aging rapidly and the rise of the in-home bathing service industry, the existing equipment in this industry is mainly of two types: inflatable bath tubs and split-type bathtubs. Inflatable bath tubs need to be operated while the elderly are lying in bed, requiring the user to turn over multiple times to get in and out of the tub. Water and drainage are very difficult, and storage is cumbersome, with inflation and deflation taking a long time. Split-type bathtubs are bulky and cannot be transported by car. Moving them on a ladder is very strenuous, requiring two or more people to lift the elderly into and out of the tub. The process is extremely painful and inconvenient, and there is a high risk of injury such as bumps and slips.
[0003] Current market-available structures fail to address the issues of transport volume and operational safety; their lack of convenient water and drainage, lifting functionality, and reliance on caregivers' physical strength for transfer increases the risk of secondary injury to the elderly. Utility Model Content
[0004] This utility model provides a manually adjustable and folding bath bed, the specific technical solution of which is as follows: A manually adjustable folding bath bed includes a foldable segmented bed frame, guardrails, scissor-type lifting legs, sliders, lead screws, lead screw bearing seats, stabilizer bars, stabilizer bar seats, lifting cranks, casters, folding hinges, and a matching bath tub. The foldable segmented bed frame consists of three bed boards connected by folding hinges, the bed boards including a first bed board, a second bed board and a third bed board; The guardrails are symmetrically arranged on both sides of the foldable segmented bed frame and are connected by hinges, allowing them to be rotated outwards 180°. Scissor-lift adjustable legs are located under the bed frame; The foldable segmented bed is equipped with a lead screw bearing seat and a stabilizer rod seat underneath, with the stabilizer rod seat located on both sides of the lead screw bearing seat; the stabilizer rod is inserted into the stabilizer rod seat to prevent tilting during lifting. The lead screw is fixed to the bottom of the bed by lead screw bearing seats at both ends, and its two ends are provided with reverse threads with opposite directions of rotation, which respectively engage with the two slider threads; the top of the scissor-type lifting leg is hinged to the slider; The crank handle is connected to one end of the lead screw, and the lead screw is driven to rotate by the crank handle; The bath tub can be disassembled and embedded into the unfolded foldable segmented bed frame; Multiple casters are installed at the bottom of the scissor lift legs; The first and third bed boards can be flipped 90° downwards to allow the three bed boards to be stacked in parallel. At the same time, the guardrail can be flipped 180° to be flush with the side of the bed board, together allowing the entire bath bed to be folded into a compact cuboid structure.
[0005] In a preferred embodiment of the manually adjustable folding bath bed, the lead screw has positive and negative threads at both ends. When rotated, the lead screw drives the slider to move in opposite directions, thereby unfolding or folding the scissor-type lifting legs and adjusting the height of the bed surface.
[0006] The preferred embodiment of the manually adjustable folding bath bed is that the guardrail is a segmented structure, each segment of the guardrail can be flipped upward and locked by hinges to form a safety guardrail during bathing; the upright guardrail can be flipped 180° to form a flat embedded storage; When folded, the first and third bed boards fold in opposite directions at 90° to the bed surface, which can prevent the bed surface from folding due to force on the front; the guardrails are flipped down and folded into the middle of the two sides of the bed boards, and when unfolded, they are fixed in the upright position by the limiting buckles.
[0007] The preferred embodiment of the manually adjustable folding bath bed is that the scissor-type lifting legs adopt an X-shaped cross hinge structure, with the middle part connected by a pin shaft, the bottom hinged with casters, and the top connected by a slider and a lead screw. The casters are silent swivel casters, and at least two casters have a brake locking function.
[0008] The preferred embodiment of the manually adjustable folding bath bed is that the matching bath tub is made of foldable soft waterproof material with hard edging, and is matched and fixed with the slots of the foldable segmented bed frame, forming a seamless bath tub space when unfolded; the edge of the matching bath tub is provided with a drain outlet for easy drainage after use.
[0009] The preferred embodiment of the manually adjustable folding bath bed is that the height adjustment range of the folding bath bed covers 350mm-750mm, which is suitable for the height of home beds, wheelchairs and nursing tables, and the crank is located on the side of the foot of the bed for easy operation.
[0010] The preferred embodiment of the manually adjustable folding bath bed is that the overall folding bath bed adopts an aluminum alloy frame, the key load-bearing components are reinforced, and the net weight is ≤20kg.
[0011] A method for assisting bathing with a manually adjustable and folding bath bed includes the following steps: Step 1: Unfold the folded bathing bed, adjust the bed height to be level with the elderly person's bed, and place the matching bathing tub; Step 2: Gently move the elderly person to the bathing bed using a sheet or transfer cloth; Step 3: Flip and lock the guardrail, then push the shower bed into the bathroom; Step 4: Perform the bathing procedure; Step 5: After bathing, drain the water, push the elderly person back to their original position, and then reverse the process to move the elderly person back to their original bed.
[0012] When folding, lower the bed to its lowest position, rotate the crank counterclockwise, the screw drives the slider to move outward, and the scissor-type lifting legs fold to their minimum height and fit against the bed bottom; the third bed board flips down 90°, the first bed board flips down 90°, and at the same time the guardrail flips horizontally 180° and stacks it on the side of the bed; the third bed board and the first bed board are both perpendicular to the second bed board, and the three bed boards form a parallel stack after folding. Beneficial effects
[0013] This utility model features a three-section folding bed frame and embedded guardrails for storage. When folded, it forms a rectangle measuring 750×920×200 mm, which can be placed in the trunk of a car. The aluminum alloy frame weighs ≤20kg, allowing a single person to carry it upstairs using a ladder. The bed height is adjustable from 350mm to 750mm for elderly people, facilitating easy movement with bed sheets. The guardrails have no protruding parts when folded, preventing scratches during transport. The height adjustment range covers various scenarios such as hospital beds, wheelchairs, and home care tables. The quick-release design of the washbasin allows it to be used as a medical examination bed.
[0014] This utility model systematically addresses the three major pain points of the bathing equipment industry: "cannot be transported, cannot be used properly, and is unsafe," providing a technical infrastructure-level solution for home-based elderly care. Attached Figure Description
