The plate 18 can be stored. Since the rails 16 and 16 are integrally formed on the floor 19, it goes without saying that the rigidity of the floor 19 can be increased.

  An ear 30 is provided at the tip of the slope plate 18, the ear 30 is suspended by a rod 31 as a connecting member, and a rotary joint 32 is provided in the middle of the rod 31, thereby enabling the rod 31 to rotate, The slope plate 18 is supported so that the upper end of the rod 31 can be moved in the direction of the front and back of the drawing by the guide means (guide groove 33) of the steering side door 17. The guide groove 33 is preferably used as the guide means, but the structure is not particularly limited as long as it is a guide rail, a guide ridge, or a similar means.

  When the vehicle 10 is operated normally with the seat arrangement shown in FIG. 1, the nut 30 a shown in FIG. 9 is loosened and removed, and the rod 31 is removed from the ear portion 30. Then, the electric motor 47 shown in FIG. 11 to be described later is not operated (for example, as shown in FIG. 1, it is detected by a sensor that the normal driver's seat 13 is in the forward position, and the electric motor 47 is based on the detection signal of this sensor. Do not operate). If it does so, only the steering side door 17 can be opened and closed, without the movement of the slope board 18 in FIG. As a result, the vehicle 10 of the present invention can be used as a normal vehicle.

  FIG. 10 is a view taken in the direction of arrow 10 in FIG. 9, and the upper horizontal guide rod 35 and the lower horizontal guide rod 36 are housed inside the steering side door 17. Then, a vertical guide rod 37 is passed to these guide rods 35 and 36 so as to be movable in the horizontal direction, and a slider 38 (see also FIG. 9) is attached to the vertical guide rod 37 so as to be movable up and down. The arm member 39 is fitted along the guide groove 33, and the upper end of the rod 31 is connected to the arm member 39. The guide groove 33 has a horizontal portion 33a and a descending portion 33b.

  The arm member 39 indicated by a solid line descends as indicated by an arrow along the guide groove 33 and reaches a position indicated by an imaginary line. As a result, the ear portion 30 indicated by the solid line descends while moving to the position indicated by the imaginary line. At this time, the vertical guide rod 31 moves to the right in the drawing while maintaining the vertical posture by the action of the two horizontal guide rods 35 and 36, and the slider 38 moves up and down along the vertical guide rod 37. The movement of the member 39 is smooth.

FIG. 11 is a view taken in the direction of arrow 11 in FIG. 9, in which the floor 19 is indicated by an imaginary line, and the slope plate 18 and the slope plate moving mechanism 40 stored under the floor 19 are indicated by solid lines.
In the present invention, the slope plate 18 is moved vertically and horizontally in the drawing. Therefore, the slope plate moving mechanism 40 includes a front horizontal guide rod 41 and a rear horizontal guide rod 42 arranged in parallel in the front-rear direction, a cross guide rod 43 passed to the guide rods 41 and 42, and the cross guide rod. The chain 44, the sprockets 45 and 46, the electric motor 47, and the control part 48 which move 43 synchronizing with the opening degree of a steering side door are comprised. The control unit 48 receives the door opening information and drives the electric motor 47.

  The configuration of the slope plate moving mechanism 40 can be changed as appropriate. In particular, the chain 44, the sprockets 45 and 46, and the electric motor 47 can be replaced with a cylinder unit (regardless of electric, hydraulic, or pneumatic). The guide rods 41, 42, 43 can be replaced with a link mechanism or the like.

  Then, the base portion of the slope plate 18 is connected to the cross guide rod 31 via hinges 49 and 49. Since the hinges 49 are used, the slope plate 18 can swing up and down (in the direction of the front and back of the drawing).

The operation of the slope plate 18 and the slope plate moving mechanism 40 having the above configuration will be described next.
12A and 12B are views for explaining the state of the slope plate when the steering side door is closed, where FIG. 12A is a plan view and FIG. 12B is a rear view.
(As shown in b, the slope plate 18 is completely stored in the storage chamber 29, and the steering side door 17 is closed.

FIGS. 13A and 13B are views for explaining the state of the slope plate when the steering side door is opened about half, where FIG. 13A is a plan view and FIG. 13B is a rear view.
As shown in (b), it shows that about half of the slope plate 18 has come out of the storage chamber 29. Due to the action of the guide groove 33, the slope plate 18 remains horizontal.
As shown to (a), the slope board 18 moves to a figure lower right.

14A and 14B are views for explaining the state of the slope plate when the steering side door is fully opened, in which FIG. 14A is a plan view and FIG. 14B is a rear view.
As shown in (b), it is shown that the tip of the slope plate 18 is lowered by the action of the guide groove 33 and is in contact with the ground 52. That is, since the tip of the slope plate 18 comes into contact with the ground 52 and the base portion remains in the storage portion 29, the slope plate 18 becomes a slope that passes between the ground 52 and the floor 19. Therefore, it is possible to get in and out of the passenger compartment by a wheelchair using such a slope plate 18.
As shown to (a), since the ear | edge part 30 and the arm member 39 are in the corner of the slope board 18, when a wheelchair gets on and off, it does not become obstructive.

The side door 17 is connected using a rod 31 as a connecting member, and the steering side door 17 is provided with a guide groove 33 including a horizontal portion 33a and a descending portion 33b as shown in FIG. When the steering seat side door 17 is closed, the slope plate 18 is stored in the storage chamber 29 (see FIG. 12B), and the slope plate 18 is moved while the steering side door 17 is being opened. Starting from the storage chamber 29 (see FIG. 13B), when the steering side door 17 is fully open or almost fully open, the tip of the slope plate 18 is the ground 5 In contact, (see FIG. 14 (b)) a rear portion of the slope plate 18 forms a slope by remaining in the storage chamber 29, to leave the fact and vehicle compartment 11 wheelchair boarding to the passenger compartment 11 via the slope plate 18 It is characterized in that it can be configured.

That is, when the steering side door 17 is fully opened, the slope plate 18 can be passed from the ground 52 to the floor 19 of the passenger compartment. Therefore, it is possible to freely get on and off the vehicle by a wheelchair using the slope plate 18. Since only the slope plate 18 is moved up and down, the wheelchair may be a normal wheelchair.
The steering side door 17 only guides the slope plate 18, and the weight of the wheelchair and the user does not act on the door. Therefore, it is not necessary to make the steering door 17 particularly strong, and the vehicle weight does not increase significantly in order to implement the present invention.

As shown in FIG. 1, the second invention is provided with rails 16, 16 extending back and forth without a rear seat just behind the normal driver's seat 13, and along the rails 16, 16. The configuration is such that the driver's seat 13 can move back and forth.

  That is, when getting into a vehicle with a wheelchair, the normal driver's seat moves backward. When a wheelchair is not used, a normal driver's seat can be arranged near the steering and operated as a normal vehicle.
