Abstract

PROBLEM TO BE SOLVED: To impart a function to reduce a physical burden imposed on a caregiver to a device that allows an elderly person or a person having walking difficulty to be transferred mutually between a vehicle and a wheelchair.SOLUTION: A connection board is connected between the seat surface of a wheelchair and a mount, attached in advance to a seat of a vehicle, so as to allow a legless chair, having a sliding means provided on the rear of its seat surface, to be movable on the connection board. The legless chair is mounted with a means to fix it to each of the seat surface of the wheelchair and the mount of the seat. As a result, it allows the legless chair, on which a person to be cared is seated, to be slidable mutually between the vehicle and the wheelchair with a small force. In addition, the wheelchair is imparted with a foldable structure, thereby allowing the wheelchair to be stored in a trunk or the like of the vehicle when not in use. Moreover, the wheelchair is configured so that an easily disassemblable and removable handle can be attached thereto in order to allow the person to be cared to drive the wheelchair on his/her own.

Description

  The present invention relates to a device for caring for a person with a walking disability, and relates to a seat-carrying device that enables a cared person to get on and off a car while sitting on a seat. .

  Barrier-free housing and transportation are advocated. Especially in our country in recent years, the population is aging so much that it is necessary to care for elderly people and people who are unable to walk. In order to cope with this, a wheelchair having a self-propelled function and a function of assisting a user to stand up has been developed.

  In addition, since there are many opportunities to use a car for middle- and long-distance movements, not only for elderly people and people who have difficulty in walking, there is an assistance device for assisting the movement of a cared person from a wheelchair to a car. Has been developed.

  For example, in Patent Document 1, a handle and a handrail attached to a metal column, a jack that can move up and down a sliding seat around a bolt, a fixing base, a base base to which the base is attached, and a bolt An assistance assistance vehicle for transfer composed of an opening / closing arm attached to a shaft and a caster for movement is disclosed.

  Patent Document 2 discloses a wheelchair having a structure in which the seat surface can be moved up and down and turned, and the seat surface can slide backward. However, these devices require a caregiver to lift the cared person's body when the cared person is transferred to a car, and there is room for improvement from the viewpoint of reducing the burden on the caregiver.

  And in order to cope with such a subject, this inventor is disclosing the seat conveyance apparatus in Japanese Patent Application No. 2011-133698. However, while proceeding with the study to put the seat and chair conveying device according to the patent application into practical use, there is a problem that the seat inclination of the passenger car and the adjustment method thereof are various and it may be difficult to cope with it. Newly revealed.

  On the other hand, in the material drawing transport device disclosed in Japanese Patent Application No. 2011-133698, a hand rim used for a general wheelchair is not attached for the sake of overall compactness and handling of parts. Even when the caregiver's own hand was movable, it was extremely difficult to move the wheelchair by himself.

  JP 2001-037814 A   JP 2002-186648 A

  Therefore, an object of the present invention is to provide a device capable of reducing the physical burden of a caregiver to an apparatus that can transfer elderly people or people who are unable to walk to each other between an automobile and a wheelchair. Furthermore, it is to improve versatility.

  In order to solve the above problems, the present invention provides a device that can be transferred between a car seat and a wheelchair while the cared person is seated, and a change in the inclination of the cared person's seating surface. This is a result of studying the means for moving by the cared person himself to replace the conventional hand rim.

  That is, the present invention has means for fixing to a seat of an automobile and has a seat base on which a seat can be mounted, a pair of front wheels, a pair of rear wheels, and a mounting surface for the seat. The wheelchair for transporting the seating chair, and the seating chair provided with sliding means on the back side of the seating surface, and having fixing means for fixing the seating chair base and the mounting surface of the wheelchair. And a connecting plate for moving the seat chair between the seat base and the mounting surface, wherein the front wheel is a frame constituting the wheelchair. The rod-shaped member has a tubular member divided at a substantially central portion, and one end is fixed to any one of the members at the divided portion, The other end is biased by a separately provided spring on the inner peripheral side of the other tubular member A seated chair transporting device, wherein a bent portion having a rotation shaft is provided in the inserted portion, and the rod-shaped member is foldable by pulling out and bending the bent portion. It is.

  Further, the present invention is the seat chair transporting apparatus, wherein the sliding means is a free bearing.

  The connecting plate is joined to the seat base by engagement of a joining bolt provided on the seat base side and a joining hole provided on the connecting plate side, and the wheelchair. It is the said seat chair conveyance apparatus characterized by joining to the said wheelchair by engagement of the joining pipe provided in the side, and the joining rail provided in the said connection board side.

  Further, the present invention is the seat chair transporting apparatus, wherein the mounting surface is adjustable in height and angle, and the joining pipe and the joining rail have angle adjusting means.

  In the present invention, the two ends of the handle formed in a U-shape are joined by joining one end of two L-shaped rod-shaped members with a joining means that can be removed at any time. A lever for operating a brake wire in which an inner wire is inserted inside an outer cable is provided near both ends of the pair of rear wheel shafts of the wheelchair so as to be rotatable. Two are attached, and the brake wire is joined to the vicinity of the outer periphery of each of the pair of rear wheels of the handle, and is pressed against the outer periphery by operating at least one of the levers, thereby joining the handle and the outer periphery. A friction member is attached, and the handle is rotated while the friction member is in pressure contact with at least one of the outer circumferences. Rotating the at least one of the rear wheel of the pair, and wherein the movement is possible, it is said of seat transport device.

  In the present invention, the wheelchair is provided with a handle for an assistant to push the wheelchair, the handle is provided with a brake lever, and the brake lever is fixed while being attracted to the handle side. The above-mentioned seat chair transporting apparatus is characterized in that a hook is provided.

  The seat chair conveying device of the present invention uses a seat chair having a sliding device attached to the back side of the seat surface, and a seat between a seat chair base previously attached to an automobile seat and a wheelchair. The seat can be slid using the connecting plate joined to the child base and the wheelchair. For this reason, even if the cared person is seated, the seat chair can be moved in the horizontal direction with a small force, so the burden on the assisting side can be extremely reduced.

  Further, since the seat chair transporting apparatus of the present invention is provided with means for adjusting the height and angle of the mounting surface on which the seat is placed within a certain range, for example, from a light passenger car to a normal car It is possible to transfer to various car models.

  In addition, the wheelchair used in the present invention is capable of flipping up the front wheel, and when used in combination with the height and angle adjustment means of the mounting surface of the seat chair, it becomes compact when not in use, such as a car trunk And can be used on the spot after the car arrives at the destination.

  Moreover, since the wheelchair used in the present invention activates the rear wheel, it can be attached with a U-shaped handle that can be operated by the cared person himself. Is also possible.
