JP6261434B2 - Assistance for getting on and off the car - Google Patents

Description

  The present invention relates to a device that assists in getting on and off a person who cannot get on and off a car by himself such as a person who needs care, and more particularly relates to a device that assists movement between a wheelchair and a seat of a car.

  When a person who uses a wheelchair and cannot get up by himself / herself from a sitting position in a wheelchair (hereinafter referred to as a “subject”) is to get in and out of the car, A person who assists the person to be assisted (hereinafter referred to as an assistant) raises the person from the wheelchair and moves it to the car seat as it is.

  It is relatively easy for an assistant to hold a person to be supported and get up from a wheelchair. However, because the space for getting on and off a general car is small, an assistant holding the assistant cannot get on the car as it is and cannot place the assistant on the seat. Is not easy.

  In addition, even if the wheelchair is as close as possible to the car seat, a gap will be created between the wheelchair seat and the car seat, so the assistant must make the person who stands up exceed the gap between the two seats. There is also a risk that the assistant will accidentally drop the assistant in the gap.

  In order to make it easier for an assistant to get on and off, an automobile manufacturer provides a welfare vehicle having a movable seat that can be moved between the inside and outside of the vehicle. If such a welfare vehicle is used, it is only necessary to place a wheelchair next to the movable seat arranged outside the vehicle, and to allow the assistant to sit on the movable seat outside the vehicle, and then move the movable seat into the vehicle. However, welfare vehicles are more expensive than regular cars.

  Conventionally, there has been proposed an apparatus for getting a passenger to get on and off a car without using a welfare vehicle prepared by an automobile manufacturer (see, for example, Patent Document 1). It is difficult to say that the installation of the apparatus is easy and inexpensive because it is necessary to attach a mechanism for lowering to the vehicle body.

  This boarding / alighting aid is composed of a base 2 and a pedestal 4. This boarding / alighting assisting device is used by mounting the base 2 on the seating side entrance so that the seat surface 4a of the base 4 comes to the side of a seat such as the passenger seat side of the automobile.

  The shape of the base 2 is not particularly limited. However, as shown in FIGS. 4 and 5, the base 2 is arranged so as to straddle the edge 24 of the entrance 14 on the seat 16 side, and one end side is below the seat 16. The other end side is disposed outside the entrance and the pedestal 4 can be supported on the other end side. For example, a guide rail 20 for sliding the seat 16 back and forth is provided under the seat 16 such as a passenger seat, and one end of the base 2 is inserted into a gap between the guide rail 20 and the floor in the vehicle. To do.

Normally, the edge 24 of the entrance / exit is raised from the floor surface inside the vehicle body 22, and therefore, in this embodiment, two legs 8 are provided on both side edges of the lower surface of the base 2 in order to hold the raised edge 24. The concave portion 10 is provided in a portion corresponding to the edge 24 of the leg portion 8. The concave portion 10 constitutes a support portion that supports the base 2 with the inner surface upper end portion 10 a in contact with the upper surface of the edge 24.

  A support column 6 for mounting the pedestal 4 is provided on the other end side of the base 2. The shape of the column 6 may be any shape such as a prismatic shape, a cylindrical shape, or a columnar shape in addition to a rectangular tube shape. The base 4 can be attached to and detached from the support column 6. A mounting portion 4 b that holds the upper end portion of the column 6 is provided on the lower surface side of the pedestal 4. The mounting portion 4b has a concave portion 4c having a planar shape corresponding to the planar shape of the upper end portion of the column 6 on the inner side, and the upper end portion of the column 6 is fitted into the concave portion 4c for mounting. The mounting and dismounting structure of the base 4 is not limited to this, and a member provided on the lower surface side of the base 4 is fitted inside the square cylindrical or cylindrical column 6 and is attached by fastening bolts and nuts. You may do. The pedestal 4 does not necessarily need to be detachable from the base 2 and may be configured integrally with the base 2.

  When a person sits on the pedestal 4 mounted on the other end of the base 2 and a load is applied to the other end of the base 2, the base 2 has one end with the inner surface upper end 10a of the recess 10 as a fulcrum according to the principle of leverage. Although the side is lifted and tends to tilt to the other end side, the upper surface of the base 2 comes into contact with the guide rail 20 by inserting one end of the base 2 below the guide rail 20, and further tilting of the base 2 is prevented. The relationship between the height of the upper surface on one end side of the base 2 and the upper end portion of the inner side surface of the recess 10 is set so that the base 2 is in a horizontal state when the upper surface of the one end side contacts the guide rail 20.

  A stopper 12 protruding upward is provided at one end of the base 2. The stopper 12 engages with the guide rail 20 when one end side is lifted by applying a load to the other end side of the base 2, and prevents the base 2 from sliding out of the entrance / exit. In this embodiment, the stopper 12 is necessarily provided because the inner surface of the recess 10 engages with the edge 24 of the entrance 14 and serves as a stopper that prevents the base 2 from sliding in the removal direction. There is no need.

  When attaching the boarding / alighting aid to the entrance / exit 14 of the automobile, first, only the base 2 is attached to the entrance / exit 14, and then the base 4 is attached to the column 6 of the base 2, so that the installation to the entrance / exit 14 is easy. Become. When the base 2 is attached to the entrance 14, the other end side (the column 6 side) of the base 2 is lifted above the one end side and tilted so that one end is inserted under the guide rail 20 and the stopper 12 is guided by After passing under the rail 20, the other end is lowered so that the edge 24 is fitted into the recess 10. Thereby, the upper surface of the one end side of the base 2 engages with the guide rail 20, and it fixes in the state in which the upper surface of the base 2 became horizontal. Even when the stopper 12 is not provided on one end side, the mounting procedure of the base 2 is the same.

  The base 2 is made of a material that can withstand a load when a person is seated on the pedestal 4, such as steel, stainless steel, aluminum, or reinforced plastic.

  In this embodiment, the leg portion 8 is provided on the lower surface side of the base 2, but the leg portion 8 is not necessarily provided. On the lower surface of the base 2, it is only necessary that a support portion that supports the base 2 in a correct posture is provided at a position corresponding to at least the edge 24. The correct posture of the base 2 is a posture for making the seat surface of the pedestal 4 attached to the support column 6 substantially horizontal, and the base 2 itself does not need to be horizontal.

  In order to prevent the edge 24 of the entrance 14 from being damaged, an elastic member 28a such as rubber or resin may be provided on the edge of the recess 28 that holds the edge 24 as shown in FIG. . The elastic member 28a may be provided integrally with the leg portion 26 on the lower surface of the base 2a, or may be detachably attached to the edge of the recess 28 provided in the leg portion 26. . In this case, by setting the inner width of the elastic member 28a to be substantially the same as or slightly narrower than the width of the edge 24, the base 2a holds the edge 24 more stably by the elastic force of the elastic member 28a. Therefore, the position of the base 2a attached to the entrance / exit 14 is stabilized, and safety is improved.

  When the stopper 12 is provided, the base does not necessarily have to hold the edge 24 (see FIG. 4 or FIG. 5) of the entrance 14. An embodiment in which the base does not have a structure for holding the edge 24 is shown in FIGS.

  In the embodiment of FIG. 7, the leg portion 30 is provided only on the other end side (the side where the support column 6 is provided) of the lower surface of the base 2 b, and is provided on the one end side where the stopper 12 is provided. Absent. The leg 30 is provided with a notch 30 a at a position corresponding to the edge 24 of the entrance 14. The notch 30a engages with the edge 24 when the base 2b is attached to the entrance 14 and prevents the base 2b from being displaced toward the inside of the vehicle. In such a structure, since the thickness of one end side of the base 2b inserted under the seat is reduced, it is difficult to interfere with the floor surface in the vehicle when the one end is inserted under the seat, and it is easy to attach to the entrance 14. is there.

  In the embodiment of FIG. 11, leg portions 36 having a uniform thickness are provided on both side edges of the lower surface of the base 2d. Although the distance between the guide rail 20 and the edge 24 may vary depending on the vehicle type, the base 2d can be brought into contact with the upper surface of the edge 24 at any position on the lower surface of the leg portion 36. Sex is obtained.

  Further, the stopper 12 is unnecessary when a structure is provided on the lower surface side of the base that serves as a stopper that interferes with the edge 24 of the entrance 14 and prevents the base from sliding outward. An embodiment of a base not provided with the stopper 12 is shown in FIGS.

  In this embodiment, a substantially L-shaped engagement member 32 having a protruding portion 32b protruding downward on one end side is provided at a position corresponding to the edge 24 on the lower surface of the base 2c. One end of the base 2 c is inserted under the guide rail 20 and attached to the entrance 14 so that the protruding portion 32 b of the engaging member 32 is located inside the edge 24 of the entrance 14. Thereby, the protrusion part 32b of the engaging member 32 engages with the edge 24, and the sliding to the removal direction of the base 2c is prevented. Even if a load is applied to the other end of the base 2c, one end of the base 2c is engaged with the guide rail 20 to prevent the one end from being lifted, so that the protruding portion 32b passes over the edge 24 and slides outward. Never do. The engaging member 32 constitutes a support portion that supports the base 2 c with the lower surface 32 a in contact with the upper surface of the edge 24 when the base 2 c is attached to the entrance 14.

  As shown in FIG. 10, the engaging member 32 has a high versatility because its position in the base 2c can be adjusted by a position adjusting mechanism 34 made of, for example, a bolt and a nut. The function of adjusting the position of the base 4 attached to 2c can be provided.

  The boarding / alighting assistance apparatus described above is used by being attached to a boarding / alighting opening on the target seat side when a wheelchair user (subject) gets on or off the car. When the boarding / alighting aid is attached to the entrance of the automobile, the seat surface 4a of the pedestal 4 is disposed on the side of the target seat.
