Description

Wheelchair-compatible bed frame

The present invention relates to a bed frame incorporating a wheelchair, and in particular, to a bed frame that can exchange installation positions of a side frame and a collapsible door frame and can be combined with a wheelchair.

In the past, most of the nursing beds were fixed mattresses, which did not consider patients with limited mobility, or even the disabled. Therefore, when moving a patient with reduced mobility or a disabled person from a care bed to a wheelchair, the caregiver is physically exhausted and even injured.

At present, there are nursing beds with wheelchairs combined with bed frames, so that the wheelchair can be transformed into a mattress that matches the bed frame, or it can be transformed into a general wheelchair for transporting patients.

One of the prior art for a bed frame that can be combined with a wheelchair is Korean Patent Publication No. KR20-0208083Y1, which discloses that the rear panel of the bed frame is pivotally connected to the end of the first side connecting portion of the bed frame and the end of the second side connecting portion of the bed frame, In addition, the first side connecting part and the second side connecting part are pivotally connected at the middle end of themselves by means of an intermediate joint, so that the back half of the bed frame including the tail panel can be lifted up, so that the bed frame forms an opening at the tail panel, and the wheelchair can pass through the opening. into the bed frame. Korean Patent Bulletin No. KR20-0208083Y1 clearly discloses that in order to lift up the rear half of the bed frame including the tail panel, it must rely on the motor device-actuator for power supply, as well as complex mechanisms such as the main shaft lever, the secondary shaft lever, and the third shaft. To push the rear half of the bed frame up. Obviously, the bed frame disclosed in the Korean Patent Publication No. KR20-0208083Y1 needs to be equipped with a motor device, and its structure is complicated, the manufacturing cost is high, and the maintenance is not easy.

Another prior art for a bed frame that can be combined with a wheelchair is Mainland China Patent Publication No. CN105853099A, which discloses an integrated nursing bed, which includes a bed frame and a wheelchair that can be separated or combined with each other. One side part of the bed frame includes a fixed bed frame and a movable side plate, and the side part is called a movable side part. 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 is connected with one side of the one end. The other end of the movable side plate is detachably connected with the other end. The end connected with the fixed bed frame is called the fixed end, and the end connected with the movable side panel is called the movable end. One end of the fixed side portion is connected with the fixed end portion, and the other end is hinged with the movable side plate. The movable side plate cooperates with the movable end to form a gap. In practical applications, when the wheelchair and the bed frame need to be separated, the movable side plate must be turned upward, and the movable end is turned outward to form a gap. The wheelchair can be moved out of the gap. Obviously, although the integrated nursing bed disclosed in the Chinese Mainland Patent Publication No. CN105853099A does not need to be equipped with a motor device, the movable side plate must be turned upward to form a gap. Obviously, the movable side plate bears a large moment and is easily damaged. In addition, the width of the gap is limited by the length of the fixed bed frame and the movable side panel, so it is not easy for the wheelchair to enter and exit the bed frame through the narrow gap.

Another prior art for a bed frame that can be combined with a wheelchair is the Republic of China Patent Publication No. TW201914557A, which discloses a nursing bed, which includes a bed frame and a wheelchair.
