Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bed equipped with a hydraulic lifting device,

An embodiment of the present invention relates to a bed capable of adjusting the angle of a back portion including a hydraulic lifting device using a pedal.

Generally, a fixed bed in which the shape and height of the bed is fixed is mainly used. However, even in the case of such a fixed bed, a bed used in a hospital or the like can be deformed into a form in which a part of the body such as a head, a leg, and a waist is inclined up and down in consideration of the condition of the patient.

The bed used for a patient or an elderly patient who is inconvenient in behavior has a structure in which the backrest portion of the user is angled upward, thereby providing convenience in use.

Therefore, a user who is inconvenienced can raise one side of the mattress to watch TV, read and relax. Such an angle adjusting structure of the mattress is made in accordance with the ascending and descending of the screw shaft by the rotation of the driving motor, and the user can control the operating time of the driving motor and adjust the angle to a desired angle.

However, since the structure that can elevate one side of the mattress using such a driving motor requires an electric and electronic control device for driving the motor, it is inevitable that the price is made expensive, It is inevitable to provide the above-mentioned bed only in the room where the expensive entrance fee is to be paid, and it is difficult to provide the bed in the multi-room which occupies the majority.

Accordingly, it is common in the multi-room to be provided with a bed capable of manually adjusting the angle of the backrest. Conventional manually operable beds allow the nurse or caregiver to manipulate the handle to move up and down. However, the handle for the operation is protruded out of the bed, so the user must operate the bed by tilting the waist to the height of the bed, and the elderly and women who are weak in arms have a lot of power and inconvenience to operate. There is also a risk of collision when the outwardly projecting handle is moving around.
