Description

The present invention relates to a wheelchair connecting device that allows a caregiver to connect and move two wheelchairs in a column or parallel by one person, and can also be used as a wheelchair traction device.

In recent years, while the demand for wheelchairs has increased with the increase in the number of elderly people, the shortage of caregivers has become a problem in nursing care facilities and medical sites. In particular, in the case of emergency evacuation such as in the event of a disaster, one caregiver may move multiple wheelchairs, and as one of the countermeasures, two wheelchairs are connected in parallel or in parallel and alone. A coupling device that can be moved has been proposed (Patent Document 1). Further, as a means of transportation for safely evacuating rough terrain such as sandy roads, snowy roads, and gravel roads and uphill slopes, a connected movement support tool for pulling a wheelchair has been proposed (Patent Document 2).

However, the method of connecting in tandem or in parallel described in Patent Document 1 is composed of a connecting device for connecting two wheelchairs and an elbow rest plate attached to an arm pipe of the wheelchair. It needs to be installed in a wheelchair, which requires labor and expense. Further, when the caregiver is used as a towing device for a wheelchair, there is a drawback that the caregiver faces the wheelchair and pulls and moves while looking at the traveling direction, which imposes a heavy burden on the caregiver.

Further, the wheelchair movement support tool described in Patent Document 2 is exclusively for towing a wheelchair, and it is structurally difficult to use it as a vertical or parallel connection of wheelchairs.

As described above, the following effects can be expected by using the wheelchair connecting device of the present invention.
(1) The pipes on the left and right arm pipes of the wheelchair are usually left attached and can be used by installing an intravenous drip or a table in a visible hole and can be used as a normal transport operation for a caregiver.
(2) Since the drip stick can be seen in front, the patient can always check the remaining amount of the drip.
(3) It is possible to rotate the table to the left and right outside as needed to open the front and immediately get up from the wheelchair and walk before getting up.
(4) For emergency evacuation of multiple inpatients, one nurse sits the inpatient in the wheelchair and hangs the pipe pulled out in front of it over the left and right arm pipes and prepares in the same way in advance. It is possible for two people in two wheelchairs to make an emergency escape in a short time by contacting the backrest pipe of the wheelchair.
(5) In the past, the evacuation of inpatients who were completely asleep was scheduled for emergency evacuation, in which two nurses lifted the top and bottom of the futon, lowered it to the floor, dragged the corridor in a mid-waisted position, and went to the exit. According to the present invention, one person can be placed in a wheelchair by the work of one nurse, and the pipe is hung on the left and right arm pipes so that the inpatient does not slip forward, and the pipe is fixed and can be evacuated for a short time.
(6) Two wheelchairs can be transported in parallel, and one nurse can enter between the two wheelchairs and work outdoors in hospitals and welfare facilities while watching over the left and right sides.
(7) Three of the left and right arm pipes can be extended from the pipes to the longest length, and a pin can be inserted at the overlapping position of the respective holes to grasp the tip of the pipe at the front of the wheelchair and pull forward. The front part of the wheelchair tends to be lifted, and it can be easily pulled on rough roads, climbing slopes, etc. without any trouble.
(8) From a car with casters on the front wheels that is easy to rotate with the groove of the pipe extracted under the front and rear wheels of the wheelchair facing up and the upwardly curved part at the tip of the groove at the beginning when driving on a snowy road. The foot plate of the caster car of the front wheel that is installed under the tire (large car) at the rear and the front wheel and the rear wheel are inserted into the pipe so that the large rear wheel tire can easily rotate without slipping on the snow. It is possible to move forward stably without shaking and rotating left and right and without filling the snowy road.
