Description

Technical Field

[0001] This utility model relates to the field of bathing aids technology, and in particular to a three-fold stainless steel bathing aid. Background Technology

[0002] For bedridden or mobility-impaired elderly people, bathing is a rather complicated matter. Even with the assistance of several family members, bathing an elderly person is very time-consuming and laborious. Therefore, it is necessary to provide more convenient and helpful assistance for the cleaning of elderly people with limited mobility.

[0003] Currently, most in-home bathing services use two-piece bathtubs or two-fold bathing beds. Two-piece bathtubs have disadvantages such as being inconvenient to move and transport, and being prone to leaks. Two-fold bathing beds are inconvenient to transport and move after folding, and the use of square tubing in the main body also increases the weight of the base materials. In addition, the method of using a rotating straight rod to convert into an internal push-pull steel cable to lift the bed sheet also has the risk of being unstable and easily falling under the weight of the elderly.

[0004] Therefore, existing bathing beds need to be improved to enhance their ease of use and safety. Utility Model Content

[0005] This utility model addresses the technical problems of existing two-fold bathing beds being inconvenient to transport and move, and the sheets not being securely fixed and easily falling off, by providing a three-fold stainless steel bathing bed.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The three-fold stainless steel bathing bed includes a bed frame, a sheet, and a control box. The bed frame adopts a three-foldable main frame, supported by three arched, foldable legs on both sides and in the middle. The head of the sheet is fixed to the two corners of the head of the bed frame with carabiners, and the tail of the sheet is raised and lowered by steel cables. The control box is installed at the tail of the bed frame and includes a central spindle, a one-way anti-backlash ratchet, a pawl, a ratchet switch, and a crank. Turning the crank rotates the central spindle, causing the two steel cables to wind together on the central spindle. Turning the ratchet switch changes the relative position of the pawl and the one-way anti-backlash ratchet, thus achieving one-way anti-backlash for the raising and lowering of the steel cables.

[0008] Furthermore, the steel cable is assisted by two sets of fixed pulley bearings to achieve the two strands combined into one. One set of fixed pulley bearings is fixed in the middle of the rear of the bed, and the other set of fixed pulley bearings is fixed at the two corners of the rear of the bed. The steel cable passes through the fixed pulley bearings fixed at the two corners of the rear of the bed, passes through the steel pipe at the rear of the bed, and passes through the fixed pulley bearing fixed in the middle of the rear of the bed. The two strands are combined and wound around the central main shaft inside the control box.

[0009] Furthermore, the folding and limiting of the bed body is achieved through two double 90-degree bending elbow-shaped folding joints.

[0010] Furthermore, the bow-shaped, foldable bed legs are opened and closed and supported by L-shaped iron sheet side hinges.

[0011] Furthermore, the bow-shaped foldable bed legs located on both sides of the bed are symmetrically distributed, while the bow-shaped foldable bed leg located in the middle of the bed is a reverse convex shape that tapers towards the center.

[0012] Furthermore, the three sections of the bed are folded to unequal lengths and are folded in a Swiss roll fashion.

[0013] Furthermore, the upper surface of the bed sheet is formed with double Y-shaped reinforcing ribs.

[0014] Furthermore, the surface of the bed sheet has multiple drainage holes.

[0015] Furthermore, the control box is rotatably connected to the steel pipe at the tail of the bed.

[0016] Furthermore, the bow-shaped, foldable bed legs at the rear of the bed are equipped with fixing blocks for fixing the control box after being opened.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model provides a three-fold stainless steel bathing bed. It utilizes a unidirectional anti-backward ratchet system to wind up the steel cable, ensuring even force distribution and preventing backward movement. Two sets of fixed pulleys assist in winding up and releasing the cable, allowing for effortless and safe control of the elderly person's entry and exit from the water. This provides more assistance for bathing and cleaning disabled elderly individuals, improves the efficiency of bathing assistants, and offers better services to disabled elderly people. Furthermore, the three-fold bed can be folded in a Swiss roll fashion, facilitating transport and handling by car, making it more suitable for providing in-home bathing services.

Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] like Figure 1-8 As shown.

[0032] The three-fold stainless steel bathing bed provided by this utility model includes a bed frame, a bed sheet and a control box. The three-fold stainless steel bathing bed can be used in conjunction with an inflatable bathtub.

[0033] The bed frame 1 adopts a three-fold retractable main frame, supported by three bow-shaped, foldable bed legs 4 on both sides and in the middle. Figure 3As shown. Specifically, the main frame and the three bow-shaped foldable bed legs are all made of circular hollow stainless steel tubes, minimizing welding processes and reducing weight while increasing sturdiness. The folding and limiting of the bed body 1 are achieved through two double 90-degree bending elbow-shaped folding joints 5.

[0034] The bow-shaped, foldable bed legs 4 are opened and closed and supported by L-shaped iron sheet side hinges 6, as shown in the image. Figure 4 As shown. The arched, foldable bed legs on both sides of the bed frame 1 are symmetrically distributed, while the arched, foldable bed leg in the middle of the bed frame 1 is a reverse-convex shape that tapers inwards. The three sections of the bed frame 1 are of unequal length and can be folded together without conflict, performing a Swiss roll-like loop fold, such as... Figure 5 As shown. It facilitates car transportation and handling, and is more suitable for providing in-home bathing services.

[0035] The head sides of the bed sheet 2 are secured to the two corners of the head of the bed frame 1 via carabiners 7, and the tail sides of the bed sheet 2 are raised and lowered by steel cables 8. To improve the support of the bed sheet 2, double Y-shaped reinforcing ribs 9 are formed on the upper surface of the bed sheet 2, such as... Figure 6 As shown. To facilitate the raising and lowering of the sheet 2 in water and reduce resistance, the surface of the sheet 2 is provided with multiple drainage holes 10.

[0036] The control box 3 is installed at the rear of the bed frame 1. Preferably, the rocker arm and the entire control box 3 are foldable to save more storage space. Specifically, the control box 3 is rotatably connected to the steel tube at the rear of the bed frame 1. To facilitate the support and fixation of the control box 3 during use, the bow-shaped foldable bed leg at the rear of the bed frame 1 is provided with a fixing block 11 for fixing and supporting the control box 3 after it is opened.

[0037] Specifically, the control box 3 includes a central spindle 12, a one-way anti-reverse ratchet 13, a pawl 14, a ratchet switch 15, and a crank 16, as shown below. Figure 7 and Figure 8 As shown. By turning the crank handle 16, the central spindle 12 is rotated, and the one-way anti-reverse ratchet 13 rotates and prevents it from retracting, thereby causing the two steel cables to be wound together on the central spindle 12. By turning the ratchet switch 15, the relative position of the pawl 14 and the one-way anti-reverse ratchet 13 is switched, thereby achieving one-way anti-reverse of the raising and lowering of the steel cable 8. While ensuring the safety of the elderly, the bed sheet 2 can be lowered or raised in the bathtub.

[0038] The unidirectional anti-backward ratchet 13 winds up the steel cable 8, ensuring even force application and effectively preventing backward movement. The ratchet switch 15 operates as follows: When rotated to the L position, the opening of the switching plate inside the pawl switch or the slider controls the acute angle of the ratchet, locking it in place. At this time, only clockwise rotation is possible, while the opposite switching plate or slider is at the obtuse angle of the ratchet. Similarly, when rotated to the R position, the opening of the switching plate inside the pawl switch or the slider controls the acute angle of the ratchet, locking it in place. At this time, only counterclockwise rotation is possible, while the opposite switching plate or slider is at the obtuse angle of the ratchet. When in the intermediate position, there are no rotation restrictions in any direction. The ratchet components can be directly purchased as finished products from the market; they are standard parts in the design and manufacture of mechanical devices and do not require in-house design and production, nor are they parts requiring protection. The steering control switch, as a component of this part, only needs to be equipped with a directly connectable rotating shaft to work in conjunction with the steel cable.

[0039] By winding or releasing the steel cable, the elderly can be easily and safely controlled to enter or exit the water. The specific operation is as follows: Turn the crank 16 outside the control box 3 clockwise. The central spindle 12 inside the control box 3 rotates, winding up the two combined steel cables 8. Simultaneously, it pulls the two sides of the end of the sheet 2, raising the sheet 2 and lifting the elderly person's body to the surface as water is released from the sheet. During this process, if the ratchet switch 15 is in the clockwise position (L position), even if the crank 16 is released, it will not rotate back and cause the elderly person to suddenly fall back into the water. Conversely, by controlling the crank 16 to rotate counterclockwise, the steel cable 8 is slowly released, and the sheet 2 slowly lowers, adjusting the depth of the elderly person's body in the bathtub. When the ratchet switch 15 is in the middle position, both directions are no longer controlled by the ratchet, allowing free ascent or descent to the appropriate position. After locking the ratchet switch 15, the bathing assistance function is better completed.

[0040] Specific operating procedures: To raise the bed sheet: Set the ratchet switch 15 to the L position, hold the control handle 16 firmly, and turn it clockwise to wind up the steel cable and tighten the sheet. To lower the bed sheet: Set the ratchet switch 15 to the R position, hold the control handle 16 firmly, and turn it counterclockwise to loosen the steel cable and release the sheet. To adjust the bed sheet freely: Set the ratchet switch 15 to the middle position, and lock it after adjusting to the desired position. This design, through its mechanical self-locking feature, achieves both effortless operation and ensures the safety of the elderly during bathing.

[0041] Specifically, to save time and effort, the steel cables 8 are respectively assisted by two sets of fixed pulley bearings to achieve the two strands being wound together on the central main shaft 12 of the control box, one of which is fixed in the middle of the tail of the bed 1 (e.g. Figure 4The middle pulley 17), another set of fixed pulley bearings are fixed at the two corners of the tail of the bed 1. The steel cable 8 passes through the fixed pulley bearings fixed at the two corners of the tail of the bed, passes through the steel pipe at the tail of the bed, and passes through the fixed pulley bearing fixed in the middle of the tail of the bed. The two strands are wound together on the central main shaft 12 inside the control box.
