Description

Bed frame capable of being combined with wheelchair

Technical Field

The utility model relates to a bed frame that combines the wheelchair especially relates to a bed frame that position just can combine the wheelchair can be installed in the exchange of side frame and the portal that can fold up.

Background

Most of the conventional nursing beds are fixed mattresses, and patients with inconvenient actions or even incapacitators are not considered. Therefore, when a patient or a disabled person who is inconvenient to carry and move moves from the nursing bed to the wheelchair, physical strength of the nursing personnel can be consumed, and even the nursing personnel can be injured.

The existing nursing bed with a wheelchair combined with a bed frame can convert the wheelchair into a mattress matched with the bed frame and also can be converted into a state of a common wheelchair for transporting patients.

One prior art of a bed frame capable of being combined with a wheelchair is korean patent publication No. KR20-0208083Y1, which discloses that a tail panel of the bed frame is pivotally connected to a first side connecting portion of the bed frame and a rear end of a second side connecting portion of the bed frame, and the first side connecting portion and the second side connecting portion are pivotally connected at their middle ends by means of an intermediate joint, so that a rear half portion of the bed frame including the tail panel can be lifted upward, so that the bed frame forms an opening at the tail panel, from which the wheelchair can be moved into the bed frame. Korean patent publication No. KR20-0208083Y1 discloses that in order to lift the rear half of the bed frame including the rear panel upward, the rear half of the bed frame must be lifted up by a complicated mechanism such as a spindle lever, a secondary shaft lever, and a third shaft, which is powered by a motor device-actuator. It is apparent that the bed frame disclosed in korean patent publication No. KR20-0208083Y1 requires a motor device, and is complicated in mechanism, high in manufacturing cost, and not easy to maintain.

Another prior art that can be combined with a bed frame of a wheelchair discloses an integrated nursing bed, which comprises a bed frame and a wheelchair that can be separated from or combined with each other, as disclosed in chinese patent publication No. CN 105853099A. One side of the bed frame comprises a fixed bed frame and a movable side plate, and the side is called a movable side. The other side of the bed frame is called the fixed side. One end of the fixed bed frame is hinged with one end of the movable side plate, and the other end of the fixed bed frame is connected with one side of one end part. The other end of the movable side plate is detachably connected with the other end part. The end connected to the fixed frame is called the fixed end, and the end connected to the movable side plate is called the movable end. One end of the fixed side edge part is connected with the fixed end part, and the other end of the fixed side edge part is hinged with the movable side plate. The movable side plate is matched with the movable end part to move, so that a gap is formed. In practical application, when the wheelchair needs to be separated from the bed frame, the movable side plate needs to be turned upwards, and the movable end part needs to be turned outwards, so that a gap is formed. The wheelchair can be removed from the gap. Obviously, although the integrated nursing bed disclosed in chinese patent publication No. CN105853099A does not need to be provided with a motor device, the movable side plate must be turned upwards to form a notch, and obviously, the moment borne by the movable side plate is large, and the integrated nursing bed is easily damaged. In addition, the width of the gap is limited by the length of the fixed bed frame and the movable side plate, so that the wheelchair is not easy to enter or exit the bed frame from the narrow gap.

Another prior art that can be combined with a bed frame of a wheelchair discloses a nursing bed, which includes a bed frame and a wheelchair, in taiwan patent publication No. TW 201914557A. The head panel, the tail panel, the foldable first side connecting part and the second side connecting part of the bed frame form an accommodating space of the bed frame. A part of the foldable first side connecting part is horizontally folded relative to the head panel to form a notch. The wheelchair can move into the accommodating space through the notch. The bed frame disclosed in taiwan patent publication No. TW201914557A does not require a motor device, and the foldable first side connecting portion does not receive a large moment when the notch is formed. The width of the gap formed at the folded first side connecting part of the bed frame is also larger. The foldable first side connecting part can be provided with a support column and wheels, so that a user can save labor when folding the foldable first side connecting part. However, the bed frame disclosed in taiwan patent publication No. TW201914557A has the foldable first side connection portion installed at the left or right side of the bed frame, and the installation position of the foldable first side connection portion cannot be changed depending on the configuration of the room where the nursing bed is to be installed.
