Description

An electric bed-chair convertible bed with a bed board mattress on the calf position that can be folded down

technical field

The utility model relates to necessities for human life, which is an electric bed-chair conversion bed with a lower leg part of the bed board mattress, which 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 most patients who can sit up and walk around, an electric bed chair that can sit comfortably (with a backrest and feet on the ground) can be converted into a hospital bed, which facilitates the patient to stand and walk on the ground, and reduces bed rest for the patient. Time, reduce the occurrence of complications to create the 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.

In order to solve the functional deficiencies in the existing electric bed chair and hospital bed technology, I have previously applied for "An electric bed chair conversion hospital bed with side beams on one side of the calf and bed mattresses that can move inward" (patent number: ZL 2015 20694423.8), "An electric bed and chair conversion bed with a calf-position mattress that can be folded down and retracted" application date: October 13, 2015, application number: 201520796240.7) and "a calf-position mattress that can be lifted The bed and chair conversion bed" (application date: October 22, 2015, application number: 201520826372.X) utility model patent. In actual use, the above-mentioned application design still has some problems. For example, in "A Kind of Electric Bed-Chair Conversion Sickbed with Inwardly Moving Calf Position Side Beam and Bed Board Mattress", the calf position side beam on one side and the The bed board mattress can be moved inward to form the lower legs to touch the ground and enter and exit the space. However, during the inward movement process, 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 or sat on the edge of the bed first. , causing inconvenience during the conversion process of the bed and chair. In "An Electric Bed and Chair Convertible Bed with Down-folding and Retractable Calf Bed Mattress", due to the limitation of the seat height and the length of the calf bed, the calf bed mattress is composed of 2 bed board mattresses It needs to be folded down and retracted to a height of about 350mm, and the structure of the bed board push frame is quite complicated. In "A Bed and Chair Conversion Bed with Liftable Bed Board Mattress for Lower Legs", the lower leg bed board mattress needs to be lifted manually when sitting up, which is difficult for patients with insufficient physical strength and requires the help of nursing staff.

Utility model content

The utility model makes corresponding improvements aiming at the remaining problems in the design of the above application, and is also a combination of "An electric bed and chair conversion bed with a lower-leg bed mattress that can be folded down and retractable" and "A kind of lower-leg bed mattress that can be lifted up." The respective advantages of the bed-chair conversion bed make it simple in structure, and the person on the bed does not need to move the body, and can complete the bed-chair conversion function only through the controller, so as to achieve the purpose of self-care.

In order to achieve the above-mentioned goals of the electric bed-chair conversion bed, we have designed a feasible solution: 1. The calf bed mattress is composed of two parts, the proximal end and the far end. They are not connected and are independent. overall. 2. Only the mattress at the proximal end of the calf can be folded down to form a space for the lower legs and the ground with a length of about 350 mm, which solves the problem that the entire calf bed cannot be folded down due to the limitation of the height of the chair surface. 3. The bed board mattress at the far end of the calf is left on the bed, with a length of about 300mm. It can also be lifted up manually to lean against the guardrail at the end of the bed to widen the space for the lower legs and the ground.

Because there is only one bed mattress at the proximal end of the calf position that is only folded down without retraction, the structure of the push rod for folding down and raising and reset becomes quite simple, and the folding down and raising and reset of the bed board mattress for the calf position It provides uninterrupted support to the calf of the person on the bed during the process, which will not cause a sense of loss to the calf and foot, and will not cause the person on the bed to feel nervous. There is still a space of about 50mm from the ground after the bed board mattress for the calf position is folded down, which also meets the requirement that the mattress (cushion) is ≤450mm from the ground, so that the feet can touch the ground when sitting.

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