Description

An electric bed-chair convertible bed that can be folded down and retracted with a bed board mattress for the lower legs

technical field

The utility model relates to necessities for human life, which is an electric bed-chair conversion bed with a crus position bed mattress which can be folded down and retracted. It is also an electric nursing bed, and is especially suitable for use as a hospital bed.

Background technique

For a family with a small living area, an electric bed-chair conversion bed that can be used as a bed or a chair is a convenient and practical piece of furniture. For some leisure places, an electric bed that can be converted into a comfortable chair is also a good choice.

For most patients who can sit up and walk around, it is very important to convert an electric bed and chair that can facilitate them to sit up and get out of bed, because people's normal life should be sleeping on the bed. , or the patient’s condition needs to sleep on the bed according to the doctor’s advice. Long-term bed rest will cause abnormal rest time, and often have complications such as pressure sores, hypostatic pneumonia, thrombosis, and muscle disuse atrophy. Those who get up should not stay in bed too much, and those who can stand and walk should exercise more and recover as soon as possible. An electric bed-chair conversion hospital bed that allows the patient to sit comfortably (with a backrest and feet on the ground) on the chair surface. necessary conditions.

Existing multi-functional electric hospital bed also has the function of sitting up and lowering legs. Because the bed board of the lower leg is directly lowered to form a chair, because the length of the bed board of the lower leg is generally about 650mm, the chair surface is too high from the ground, and the patient's feet cannot On the ground, the general mattress is ≥ 450mm from the ground, and it is difficult for patients to get out of bed, stand and walk directly, especially for patients who are not tall.

To solve the functional deficiencies in the existing electric bed chair and hospital bed technology, I have previously applied for five utility model patent applications: "A Kind of Electric Bed Chair Conversion Bed" (application date: June 3, 2015, application No.: 201520388606.7), "An Improved Compressible Hip and Leg Bed Board and Its Mattress" (Application Date: August 3, 2015, Application No.: 201520582510.4) and "An Electric Bed and chair conversion bed" (application date: August 24, 2015, application number: 201520641014.1), "an electric bed and chair conversion hospital bed with side beams on one side of the calf and bed mattresses that can move inward" (application date: 2015 September 2, 2015, application number: 201520694423.8), "An electric bed and chair conversion bed with lower leg bed frame that can be lowered and retracted" (application date: September 22, 2015, application number: 201520756779.X), This application is also to make corresponding improvements to the problems remaining in the design of the fifth application.

In the application of "An electric bed and chair conversion bed with a lower-leg bed frame that can be lowered and retracted", the bed frame, bed board and mattress of the lower leg position can be lowered and retracted on the buttocks and thighs (abbreviated as the breech bed board, The same below, that is, the position of the seat surface), after the bed is converted into a seat, there is no obstacle in front of it, which has solved the problem of the above-mentioned previous application for the electric bed and chair conversion bed, but found in the actual use process: the lower leg bed During the process of descending and retracting the frame, the lower legs and feet of the person on the bed cannot be placed on the bed surface. They must be lifted off the bed surface first, or retracted to the chair surface first, otherwise the bed frame for the lower legs will be retracted and slid The process will cause friction and drag on the feet, and when the bed frame is retracted into place, the feet will suddenly lose support and fall to the ground. This form of electric bed-chair conversion bed may not be a big problem for healthy people, but When using it on a patient with insufficient muscle strength of the lower limbs, or in the recovery period of lower limb fractures, he is required to leave the lower leg and foot off the bed first, and the help of a nursing staff is required, so improper use may cause harm to the patient.

Utility model content

To sum up, the design of the electric bed-chair conversion bed must meet the following requirements: 1. The mattress of the lower leg bed is folded down and retracted instead of falling and retracted. Uninterrupted support of the calf is required. 2. The folding down, retraction, lifting and reset of the calf bed mattress is a gradual process, which will not cause a sense of loss to the calf and feet, and will not cause the user to feel nervous. 3. The folding down and retracting process of the mattress on the calf position meets the requirement that the mattress (cushion) is ≤450mm from the ground, so that the feet can touch the ground when sitting.

In order to solve the above-mentioned problems in "A Electric Bed-Chair Convertible Bed with Lower Leg Bed Frame and Retractable" and achieve the set goal of the electric bed-chair convertible bed, we have designed two feasible solutions: 1. Calf The bed is composed of 2 bed board mattresses, which can be folded down, and the length is folded down from 650mm to a height of about 350mm. 2. The calf position adopts a compressible bed board and mattress, the length of which can be compressed from 650mm to about 350mm, and can be folded down. 3. Only one electric push rod is used to complete the process of compressing or folding down, retracting, lifting, and resetting of the calf bed mattress, reducing the occurrence of failure rates. 4. It is driven by a sliding frame, which ensures that the rigidity of the lower leg bed board meets the requirements.

Below in conjunction with accompanying drawing and embodiment the utility model is further described:
